Next, the mist generating chamber 45 will be described.

As described above, the mist generating chamber 45 houses the mist generating unit 51 therein. Thereby, the mist generated by the driving of the mist generating unit 51 easily accumulates in the mist generating chamber 45.

Therefore, even in the case where the mist generated by the mist generating unit 51 causes density unevenness due to the passage of time or the like, since the generated mist is diffused in the mist generating chamber 45, the mist in the mist generating chamber 45 is generated. The concentration tends to become substantially uniform.

The lower end portion of the mist duct 63 facing the refrigerating chamber is opened in the mist generating chamber 45 to become a mist blowing port 64 for the refrigerating chamber, and the upper end portion communicates with the cold air supply duct 37 in the cold air duct 34.

Thereby, the wind (cold air) introduced from the air supply port 62 is blown to the inner peripheral wall of the mist generating chamber 45 (the back surface of the duct constituent member 46), and the direction is changed, and a part of the wind is blown out from the mist blowing port 64.

Therefore, the mist generated by the mist generating unit 51 in the mist generating chamber 45 is easily diffused by the convection formed by the wind introduced from the air supply port 62. Thereby, the concentration of the mist in the mist generating chamber 45 is more likely to become more uniform.

In addition, a part of the convective mist formed in the mist generating chamber 45 is supplied from the cold air supply port 39 through the mist blowing port 64, the mist duct 63 facing the refrigerator compartment, and the cold air supply duct 37 together with a part of the wind introduced from the air supply port 62.

As shown in FIGS. 4 and 5, the mist blowing outlet 67 for the vegetable compartment is provided at the lower right portion of the mist generating chamber 45, in other words, at the lower right side of the air supply port 62, at a position that does not face the mist releasing pin 57, and is connected via the communication. The mouth 44 is connected to the vegetable compartment 4. In other words, the mist blowing outlet 67 for the vegetable compartment does not face the mist releasing pin 57 in the front-rear direction.

Thereby, the wind introduced from the air supply port 62 is blown to the inner peripheral wall of the mist generating chamber 45 (the back surface of the duct constituent member 46), and the direction is changed, and a part of the wind is blown out from the mist blowing port 67 for the vegetable compartment. Therefore, a part of the mist which is convectively formed in the mist generating chamber 45 is supplied to the vegetable compartment 4 via the communication port 44 from the mist outlet 67 for the vegetable compartment together with a part of the wind introduced from the air supply port 62.

At this time, the distance L1 between the air supply port 62 into which the cold air is blown into the mist generating chamber 45 and the mist blowing port 67 for the vegetable compartment is set to be larger than the distance L2 between the air supply port 62 and the mist blowing port 65 for the micro-freezing chamber. .

Located above the mist generating chamber 45 and above the mist releasing portion 50, a micro-freezer air supply duct 68 is provided (see FIGS. 4, 6, and 8). As shown in FIG. 8, the micro-freezer air supply duct 68 communicates with the refrigerating cooler chamber 36 through the heat insulating material 38 at the rear portion, and the front portion penetrates the mist generating chamber 45 to communicate with the micro-freezing chamber 14.

Therefore, a part of the wind passing through the refrigerating cooler chamber 36, that is, a part of the cold air is directly supplied to the micro-freezing chamber 14 through the air supply duct 68 of the micro-freezing chamber (the flow of the wind is as shown in Figs. 4, 6, and 8). Arrow A2). Further, the heat insulating material 38 also serves as an insulating mechanism between the refrigerating cooler 24 and the mist discharge portion 50.

In Fig. 6 and Fig. 8, in the vicinity of the refrigerating cooler 24, at this time, on the back side, the heater 70 for heating is disposed on the side of the heat insulating material 2c of the inner box 2b. The heater 70 is energized by the energization during the defrosting of the refrigerating cooler 24, and heats the refrigerating cooler 24 and its surroundings.

Fig. 17 shows a schematic configuration of a refrigeration cycle 710 in the refrigerator of the present embodiment. In the refrigeration cycle 710, the discharge portion 27a of the compressor 27 is connected to the switching valve that switches the flow path of the coolant via the condenser 720, and at this time, is connected to the inlet portion 730a of the three-way valve 730. Further, one outlet portion 730b of the three-way valve 730 is connected to the suction portion 27b of the compressor 27 via a first capillary tube 740, a freezing cooler 25, and an accumulator 750, which are decimators for freezing. Further, the other outlet portion 730c of the three-way valve 730 is connected to the suction portion 27b of the compressor 27 via the second capillary tube 760 and the refrigerating cooler 24, which are refrigerating devices.

Here, when the storage compartment (the ice making compartment 5, the small freezing compartment 6, and the freezing compartment 7) of the freezing temperature section is cooled, the compressor 27 is driven in a state where one outlet portion 730b of the three-way valve 730 is opened. . Then, the coolant discharged from the discharge portion 27a of the compressor 27 sequentially passes through the condenser 720, one outlet portion 730b of the three-way valve 730, the first capillary tube 740, the freezing cooler 25, and the accumulator 750, and is compressed. The suction portion 27b of the machine 27 is circulated as it returns to the compressor 27.

In this process, the air around the freezing cooler 25 is cooled, and the cold air is circulated by the freezing air blowing fan 31 as described above, thereby causing the storage compartment of the freezing temperature section (the ice making compartment 5, the small freezing compartment) 6. The freezer compartment 7) is cooled.

When the storage compartment (refrigeration chamber 3, vegetable compartment 4, and micro-freeze compartment 14) of the refrigerating temperature section is cooled, the compressor 27 is driven in a state where the other outlet portion 730c of the three-way valve 730 is opened.

Then, the coolant discharged from the discharge portion 27a of the compressor 27 sequentially passes through the condenser 720, the other outlet portion 730c of the three-way valve 730, the second capillary tube 760, and the refrigerating cooler 24, and from the compressor 27 The suction portion 27b is circulated so as to return to the compressor 27.

During this process, the air around the refrigerating cooler 24 is cooled, and the cold air is circulated by the refrigerating air blowing fan 35 as described above, thereby causing the storage compartment of the refrigerating temperature section (refrigeration chamber 3, vegetable compartment 4, The micro-freezing chamber 14) is cooled.

When the chilling cooler 25 is defrosted, the defrosting heater (not shown) is energized while the operation of the compressor 27 is stopped, and the chilling cooler 25 is heated by the defrosting heater. Thereby, defrosting of the freezing cooler 25 is performed. The defrosted water generated by the defrosting is guided to the defrosting water evaporating dish 28 and evaporated after being taken up by the drain pipe 32 as described above.

At the time of defrosting of the freezing cooler 25, defrosting of the refrigerating cooler 24 is also performed. The defrosting of the refrigerating cooler 24 basically circulates the air of the storage compartment (refrigure compartment 3, vegetable compartment 4, and micro-freezing compartment 14) of the refrigerating temperature section through the cold air duct 34 by driving the refrigerating blower fan 35. get on. By circulating the air in the storage compartment of the refrigerating temperature section through the cold air duct 34, the temperature of the refrigerating cooler 24 becomes a plus temperature, whereby the temperature of the refrigerating cooler 24 rises and defrosting.

At the time of defrosting of the refrigerating cooler 24, a part of the defrosted water dripped from the refrigerating cooler 24 is taken up by the water storage container 56 of the electrostatic atomizing device 48 and stored, and the remaining portions are as described above. After being taken up by the defrosting water receiver 40, it is guided to the defrosting water evaporating dish 28 and evaporated.

Further, at the time of defrosting of the refrigerating cooler 24, by controlling the energization of the heater 70 provided in the vicinity of the refrigerating cooler 24, the defrosting can be performed more reliably by the heat of the heater 70.

The defrosting of the refrigerating cooler 24 is performed in addition to the defrosting of the freezing cooler 25 at the same time as the freezing cooler 25 cools the storage compartment of the freezing temperature section. At this time, the compressor 27 is driven, but by the state where the other outlet portion 730c of the three-way valve 730 is closed and the coolant does not flow through the refrigerating cooler 24, the refrigerating blower fan 35 is driven, and the heating is performed. The controller 70 performs power supply control.

Next, the action of the refrigerator having the configuration of the above-described mist generating mechanism will be described.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, the cold air cooled by the refrigerating cooler 24 passes through the wind generated by the air blowing action by the refrigerating blower fan 35, and passes mainly as shown by the hollow arrow in FIG. The cold air supply duct 37 is supplied from the plurality of cold air supply ports 39 to the refrigerating compartment 3.

Further, a part of the wind generated by the refrigerating blower fan 35 is directly supplied from the micro-freezing chamber air supply duct 68 to the micro-freezing chamber 14 (see an arrow A2 in FIGS. 4, 6, and 8). The cold air supplied to the refrigerating compartment 3 and the micro-freezing compartment 14 is converged after cooling of the stored goods such as foods, and is also supplied to the vegetable compartment 4 from the communication port 44 (see FIG. 5).

The cooling air supplied to the vegetable compartment 4 is cooled by the refrigerating air blower fan 35 from the suction port 43 and then cooled by the refrigerating cooler 24 to cool the storage of the vegetables and the like, and the circulation is repeated.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, a part of the wind that has passed through the refrigerating cooler chamber 36 is introduced from the air supply port 62 and supplied into the mist generating chamber 45 as indicated by an arrow A1 in FIG. 7 . Here, since the mist blowing ports 64, 65, 66, and 67 are provided at positions that do not directly face the air supply port 62, the air introduced from the air supply port 62 is blown to the inner peripheral wall of the mist generating chamber 45 (the back surface of the duct constituent member 46). When the direction is changed, the wind introduced from the air supply port 62 is blown out from the mist blowing ports 64, 65, 66, and 67, respectively.

At this time, when the electrostatic atomizing device 48 is driven, a fine mist containing hydroxyl radicals as described above is released from the plurality of mist discharge pins 57 of the mist generating unit 51. The released mist is accumulated in the mist generating chamber 45 and diffused in the mist generating chamber, and the concentration of the mist in the mist generating chamber 45 becomes substantially uniform.

Further, by introducing air into the mist generating chamber 45 from the air supply port 62, the mist in the mist generating chamber 45 is diffused and convection is formed, and the concentration of the mist becomes more uniform.

In addition, as shown by the arrow B1 in FIG. 4 and FIG. 7 , a part of the mist which is convective and has a substantially uniform concentration is supplied from the mist outlet 64 to the refrigerating compartment 3 via the mist duct 63 and the cold air supply duct 37 facing the refrigerating compartment. The mist blowing port 65 for the micro-freezing chamber is supplied to the micro-freezing chamber 14 as indicated by the arrow B2, and is supplied from the mist blowing outlet 66 for the egg carton to the egg carton 15 as indicated by the arrow B3, and is blown from the mist for the vegetable compartment. The outlet 67 is supplied to the vegetable compartment 4 via the communication port 44.

In the first embodiment described above, since the mist generating unit 51 is provided in the mist generating chamber 45, the mist generated by the mist generating unit 51 is easily accumulated in the mist generating chamber 45.

Thereby, even if the mist generated by the mist generating unit 51 generates density unevenness, since the mist diffuses in the mist generating chamber 45, the concentration of the mist in the mist generating chamber 45 becomes substantially uniform, so that the concentration can be obtained. The substantially uniform mist is supplied from the mist blowing ports 64, 65, 66, 67 to the storage compartment (refrigeration chamber 3, micro-freezing chamber 14, egg box 15, and vegetable compartment 4), so that sterilization or deodorization of these supply targets can be expected. The effect is also expected to maintain the moisturizing or freshness of vegetables and the like.

According to the first embodiment described above, the following effects can be obtained.

The water for atomization in the electrostatic atomization device 48 of the form of the mist generating device that constitutes the mist discharge device can be cooled by the water storage container (water storage portion) 56 that is the defrosting water accumulator. The defrosting water of the device 24 can thus automatically supply water to the water storage container 56, so that the user's replenishment of the water of the electrostatic atomizing device 48 can be eliminated.

The freezer refrigerator of the present embodiment employs a double evaporator type refrigerating cycle including two coolers, a refrigerating cooler 24 and a refrigerating cooler 25. Here, the ambient temperature of the refrigerating cooler 25 of the refrigerating refrigerator using the double evaporator type refrigerating cycle or the ambient temperature of the cooler of the single-evaporator type refrigerating refrigerator as in the present embodiment is removed at the time of defrosting The frost heater is heated to a positive temperature, but it is always kept at a temperature of -20 ° C or lower except during defrosting. Assuming that the water storage container is provided on the side of the cooler, even if the water storage container receives and stores the defrosted water at the time of defrosting of the cooler, the water in the water storage container is liable to freeze and is difficult to melt. Therefore, there is a problem that it is difficult to stably supply the water to the mist discharge unit 50.

In the present embodiment, in the double-evaporator type refrigerator having the two coolers of the refrigerating cooler 24 and the refrigerating cooler 25, the water storage container 56 is provided for cooling for refrigeration. The device 24 is disposed on the side of the chilled water (for example, below the refrigerating cooler 24). In the double-evaporator type freezer, the peripheral temperature of the refrigerating cooler 24 becomes a minus temperature in the cooling operation of the refrigerating cooler 24, but is much higher than the temperature of the refrigerating cooler 25. In the cooling operation of the refrigerating cooler 25 (during cooling of the storage compartment in the freezing temperature section) or the stop of the operation of the compressor 27, the cooling air blower fan 35 is circulated to the vicinity of the refrigerating compartment 3 by the air circulation of the refrigerating air blowing fan 35. The temperature is around +3 °C. Therefore, in particular, the water in the water storage container 56 provided below the refrigerating cooler 24 is less likely to freeze, and is easily melted even if it is frozen. Therefore, the mist discharge unit 50 can be stably supplied with water.

Further, in the present embodiment, since the heater 70 is provided in the vicinity of the refrigerating cooler 24, by controlling the energization of the heater 70, it is possible to more reliably prevent the water in the water storage container 56 from freezing. The mist discharge portion 50 can be supplied with water more stably.

At this time, the inner surface side (the side of the refrigerating cooler 24) of the inner case 2b may be located in the vicinity of the heater 70, and a heat conductive member made of, for example, an aluminum sheet may be attached, and the lower end of the heat conductive member may be attached. The portion extends to the vicinity of the water storage container 56, and the water storage container 56 is heated by the heat of the heater 70 by the heat transfer member. When it is configured as such, it is possible to more reliably prevent the ice in the water storage container 56 from freezing.

The mist discharge portion 50 of the electrostatic atomization device 48 constituting the mist generating device is composed of a plurality of mist discharge pins (protrusions) 57 that protrude in different directions. With this configuration, unlike the case where the protruding direction of the projection for generating mist is only one-way, the supply direction of the mist can be set to a plurality of directions, and the supply range of the mist can be widened.

The mist releasing portion 50 is configured such that the horizontal portion 53a of the water supply portion 53 is sandwiched by the mist releasing pin (protrusion) 57 and extends upward and downward in the opposite direction, so that the mist can be released in the opposite direction from the upper side and the lower side. The supply range of the mist can be widened.

Further, the horizontal portion 53a of the water supply portion 53 and the respective mist release pins 57 are arranged along the front wall 36a so as to be parallel to the front wall 36a of the refrigerating cooler chamber 36 in the cold air duct 34. This makes it possible to achieve a thinning of the front and rear direction. By arranging the mist discharge pin (protrusion) 57 in two upper and lower sections, compactness can be achieved.

The mist releasing portion 50 is configured such that a plurality of the mist releasing pins (protrusions) 57 are arranged in a line, so that the amount of mist released can be increased, the supply range of the mist can be further widened, and the thickness can be reduced. .

A configuration is adopted in which the water supply portion 53 has a curved portion 53c, and a water storage container 56 for storing water is provided below the curved portion 53c, and water stored in the water storage container 56 can be supplied to The curved portion 53c.

Thereby, the water of the water storage container 56 can be supplied to the mist discharge pin 57 via the curved portion 53c. The power supply device 52 is disposed on the opposite side of the curved portion 53c with the mist releasing portion 50 interposed therebetween. Thereby, the power supply device 52 can be moved further away from the water storage container 56.

Further, by disposing the power source device 52 and the mist generating unit 51 in parallel with the front wall 36a of the refrigerating cooler chamber 36 in the cold air duct 34, the electrostatic atomizing device can be realized. The thickness of 48 is reduced in the depth direction.

The mist discharge pin (projection) 57 of the mist discharge unit 50 of the electrostatic atomizing device 48 is disposed along the cold air duct 34. Thereby, the depth dimension of the electrostatic atomization device 48 in the front-rear direction can be suppressed, and the thickness can be reduced. Along with this, the reduction in the volume of the refrigerator can be suppressed.

In the front portion of the cold air duct 34, a air supply port 62 for supplying cold air into the mist generating chamber 45 is provided, and the mist releasing portion 50 of the electrostatic atomizing device 48 is disposed in front of the cold air duct 34. Thereby, the cooling air supplied from the air supply port 62 to the inside of the mist generating chamber 45 can be used to float the mist discharged from the mist discharge unit 50 to a distant place.

Since the air supply port 62 and the mist releasing portion 50 (the mist releasing pin 57) are disposed at positions shifted to the left and right so as to be different from the opposing positions, the cooling air supplied from the air supply port 62 to the mist generating chamber 45 is not directly blown. Go to the mist discharge unit 50 (the mist release pin 57). Thereby, it is suppressed that the mist discharge pin 57 is directly dried by the cooling air from the air supply port 62.

The refrigerator main body 1 includes a mist generating chamber 45 that houses the electrostatic atomizing device 48 having the mist releasing portion 50, and the mist generating chamber 45 is provided with a different supply target for the mist generated by the mist releasing portion 50. Multiple fog blows out.

Specifically, the plurality of mist blowing outlets are a mist blowing outlet 64 for a refrigerating compartment, a mist blowing outlet 65 for a micro-freezing chamber, a mist blowing outlet 66 for an egg box, and a mist blowing outlet 67 for a vegetable compartment. Thereby, the mist generated in the mist generating chamber 45 can be supplied to the four supply targets of the refrigerating compartment 3, the micro-freezing compartment 14, the egg box 15, and the vegetable compartment 4, and the supply range of the mist can be widened, and the effect of the mist can be enlarged. range.

The micro-freezing chamber 14, the egg box 15, and the vegetable compartment 4 in the mist supply target have a micro-freezing box 18, an egg box 15, and a vegetable box (the lower box 11 and the upper box 12), respectively, and the mist can be favorably supplied to these boxes. Inside.

At this time, the plurality of mist blowing outlets (the refrigerator outlets 64, the micro-frozen mist outlets 65, the egg box mist outlets 66, and the vegetable compartment mist outlets 67) are disposed around the mist discharge unit 50. Therefore, the mist discharged from the mist discharge unit 50 can be favorably supplied to each of the mist blowing outlets.

The mist generating unit 51 has a mist discharge pin (protrusion) 57, and a plurality of mist blowing outlets (a refrigerator chamber mist outlet 63a, a micro-freezer mist outlet 65, an egg box mist outlet 66, and a vegetable compartment). The mist blowing port 67) is disposed at a position different from the position facing the mist releasing pin 57, and even if fingers or foreign matter are inserted into the mist generating chamber 45 from these mist blowing outlets, they can be prevented from directly contacting the mist. The pin 57 is released to ensure safety.

Further, since the duct constituent member 46 forming the mist generating chamber 45 is detachable, maintenance of the mist generating unit 51 and the like can be easily performed.

(Second embodiment)

The second embodiment will be described with reference to Figs. 10 to 12 .

As shown in FIG. 11, the refrigerator main body 1 of the second embodiment has a first path member 71 that forms a cooling path 71a and a second path member 72 that forms a non-cooling path 72a.

The cooling path 71a is a space in which the refrigerating cooler 24 is housed in the refrigerating cooler chamber 36. The air (wind) passing through the cooling path 71a is cooled by the refrigerating cooler 24. At this time, the first path member 71 is a rear portion of the inner case 2b that forms the refrigerating cooler chamber 36 and the heat insulating material 73 to be described later.

The non-cooling path 72a is a space for the wind generated by the air blowing action of the refrigerating blower fan 35 to be sent to the mist generating chamber 45 without passing through the refrigerating cooler 24, and is not stored in the refrigerating cooler chamber 36. Use the space of the cooler 24.

Since the air (wind) passing through the non-cooling path 72a does not accommodate the refrigerating cooler 24, it is not directly cooled by the refrigerating cooler 24. At this time, the second path member 72 is the front portion 36a and the front portion of the heat insulating material 73.

The heat insulating material 73 corresponds to the heat insulating material 38 of the first embodiment. The heat insulating material 73 extends to the lower side of the heat insulating material 38 of the first embodiment, that is, extends further below the refrigerator cooler 24 . Further, the heat insulating material 73 is formed with a slit in a portion on the side of the mist generating chamber 45 in the thickness direction, that is, in a portion of the front portion.

The shape of the slit is for forming the non-cooling path 72a, and extends longitudinally from the lower end of the heat insulating material 73 to the vicinity of the upper end portion of the mist discharge pin 57 located at the uppermost side (refer to FIG. 11).

Further, the size of the slit in the left-right direction is arbitrary, but it is preferably equal to or larger than the range of the lateral direction in which all of the plurality of mist discharge pins 57 are accommodated.

The mist generating chamber 45 has the same first air supply port and second air supply port 74 as the air supply port 62 of the first embodiment (see FIGS. 10 to 12). The second air supply port 74 is an opening for introducing the wind generated by the air blowing action of the refrigerating blower fan 35 into the mist generating chamber 45 by the wind passing through the non-cooling path 72a (the flow of the wind is indicated by arrows C1 and C2 in FIG. 11). , C3 shows).

The second air supply port 74 is provided at a position facing the mist discharge pin 57 of the mist discharge portion 50 in the front wall portion 36a.

In other words, in the second embodiment, the second air supply port 74 is provided at the upper and lower positions (the second air supply port on the upper side is indicated as 74a, and the second air supply port on the lower side is indicated as 74b), and one second air supply port 74a is located. The second air supply port 74b is disposed behind the mist release pin 57 above the horizontal portion 53a, and the other second air supply port 74b is located behind the mist release pin 57 provided below the horizontal portion 53a.

In other words, the refrigerator main body 1 is viewed from the entire surface, and the upper second air supply port 74a is located at a position where the mist release pin 57 provided above the horizontal portion 53a is overlapped, and the lower second air supply port 74b is provided below the horizontal portion 53a. The mist release pin 57 is located at the coincident position.

According to the configuration of the second embodiment, the wind passing through the cooling path 71a in the wind generated by the air blowing action of the refrigerating blower fan 35 is cooled by the refrigerating cooler 24 in the cooling path 71a. A part of this cooled wind is introduced into the mist generating chamber 45 from the first air supply port (air supply port 62).

Since the air supply port 62 and the mist releasing portion 50 (the mist releasing pin 57) are located at positions that do not face each other, the cooling air supplied from the air supply port 62 to the mist generating chamber 45 is not directly blown to the mist releasing portion 50 (the mist releasing pin 57) ).

Thereby, the mist discharge pin 57 can be directly dried by the cooling air from the air supply port 62, and the freezing can be suppressed.

Further, unlike the case where the protruding direction of the projection for generating mist is only one-way, the supply direction of the mist can be set to a plurality of directions, so that the supply range of the mist can be widened.

The wind passing through the non-cooling path 72a in the wind (cold air) generated by the air blowing action of the refrigerating air blowing fan 35 is not cooled by the refrigerating cooler 24, but is introduced from the second air supply port 74 (74a, 74b). The mist is generated in the chamber 45. Then, the wind introduced from the second air supply port 74 is blown to the mist discharge pin 57.

In the second embodiment, the wind introduced from the second air supply port 74a (see an arrow C2 shown in FIG. 10 and FIG. 11) is easily blown to the mist release pin 57 provided above the horizontal portion 53a of the mist release pin 57. The mist outlets 64, 65, and 66 located near the mist discharge pin 57 are supplied to the respective storage compartments.

Further, the wind introduced from the second air supply port 74b (see an arrow C3 shown in FIG. 10 and FIG. 11) is easily blown to the mist discharge pin 57 provided below the horizontal portion 53a of the mist release pin 57, and is located there. The mist blowing outlet 67 near the mist discharge pin 57 is supplied to each storage compartment.

Thereby, the mist having a high concentration which is generated by the mist release pin 57 and existing in the vicinity of the mist discharge pin 57 can be easily convected, and the concentration of the mist in the mist generation chamber 45 can be easily distributed in a high state. The mist having a high concentration and a substantially uniform concentration can be supplied from the mist outlets 64, 65, 66, 67 to the storage compartment.

The wind blown to the mist discharge pin 57 is supplied to each storage compartment from the mist blowing outlets 64, 65, 66, 67 in the vicinity of the mist discharge pin 57. Thereby, the mist in the mist generation chamber 45 can be efficiently supplied to each storage compartment.

Since the wind is introduced into the mist generating chamber 45 from the plurality of different air supply ports (the first air supply port (air supply port 62) and the second air supply port 74a, 74b in the second embodiment), the wind in the mist generating chamber 45 is generated. The flow is easily complicated, so that the concentration of the mist in the mist generating chamber is more uniform.

In addition, the second embodiment has the same operational effects as those of the first embodiment.

(Third embodiment)

The third embodiment will be described with reference to Figs. 13 to 15 .

As shown in FIG. 14, the refrigerator main body 1 of the third embodiment has a first path member 71 that forms a cooling path 71a similar to that of the second embodiment, and a non-cooling path 72a that is formed in the second embodiment (see FIG. 11). The second path member 82 of the non-cooling path 82a of a different shape.

The non-cooling path 82a is a space for the wind generated by the refrigerating blower fan 35 to be sent to the mist generating chamber 45 without passing through the refrigerating cooler 24, and is a refrigerating cooler 24 that is not housed in the refrigerating cooler chamber 36. Space.

Since the air (wind) passing through the non-cooling path 82a does not accommodate the refrigerating cooler 24, it is not directly cooled by the refrigerating cooler 24. The second path member 82 is a front wall 36a and a heat insulating material 83.

The heat insulating material 83 corresponds to the heat insulating material 73 of the second embodiment. The heat insulating material 83 extends to the lower side of the refrigerating cooler 24 in the same manner as the heat insulating material 73. Further, the heat insulating material 83 is formed with a slit in a part of the mist generating chamber 45 side in the thickness direction. The shape of the slit is for forming the non-cooling path 82a, and the longitudinal direction extends from the lower end of the heat insulating material 73 to the vicinity of the rear of the horizontal portion 53a (see Fig. 14).

Further, the size of the slit in the left-right direction is arbitrary, but it is preferably equal to or larger than the range of the lateral direction in which all of the plurality of mist discharge pins 57 are accommodated.

The mist generating chamber 45 has the same first air supply port and second air supply port 84 as the air supply port 62 of the first embodiment (see FIGS. 13 to 15). The second air supply port 84 is an opening for introducing the wind passing through the non-cooling path 82a into the mist generating chamber 45 by the wind generated by the refrigerating air blowing fan 35. (The flow of the wind is indicated by arrows D1, D2, and D3 in Fig. 14 Show).

The second air supply port 84 is provided at a position facing the mist discharge pin 57 of the mist discharge portion 50 in the front wall portion 36a.

Further, the mist generating chamber 45 has a guide member 85 that guides the wind introduced from the second air supply port 84 to the plurality of mist discharge pins 57. The guide member 85 of the third embodiment is provided on the back side (back side) of the horizontal portion 53a of the mist generating unit 51, and is a triangular prism that extends in parallel along the horizontal portion 53a.

When the guide member 85 is viewed from the side surface direction of the refrigerator main body 1, one of the apex angles of the triangular shape of the guide member 85 extends to the vicinity of the center of the second air supply port 84 in the vertical direction.

According to the configuration of the third embodiment, as in the case of the second embodiment, unlike the case where the protruding direction of the projection for generating mist is only one direction, the supply direction of the mist can be set to a plurality of directions, so that it is possible to add The supply range of wide fog.

In addition, the wind passing through the non-cooling path 82a in the wind generated by the air blowing action of the refrigerating air blowing fan 35 is cooled by the cooler 24 and is introduced into the mist generating chamber 45 from the second air supply port 84.

The wind introduced from the second air supply port 84 is blown to the guide member 85 to be vertically separated.

The situation will be described later.

In addition, the defrosting of the refrigerating cooler 24 is the same as the defrosting of the refrigerating cooler 25, and the defrosting heater 70 for the refrigerating cooler 24 is heated to adhere the surface of the refrigerating cooler 24. The frost is melted and removed, and the water generated after the melting of the frost is defrosting water, which is dripped from the refrigerating cooler 24 and dropped.

Further, in the present embodiment, the front surface portion (outside the refrigerating cooler chamber 129) which is the front side of the refrigerating cooler chamber 129 is provided with an electrostatic atomizing device 135 as a mist discharging mechanism, and the electrostatic atomizing device 135 It is used to generate a mist that exerts a sterilization or deodorization effect and is supplied to the refrigerating compartment 3 and the vegetable compartment 4.

As shown in FIG. 22, the mist generating unit 136 is attached to the refrigerating cooler chamber 129 by a suitable mounting mechanism (not shown), which is disposed in front of the refrigerating cooler 24, and is cooled further toward the front than the blowing duct 37. The chamber front wall portion 129d. As shown in FIG. 23, the mist generating unit 136 includes a plurality of, for example, seven mist releasing pins 138, one water absorbing pin 139, a conductive sheet 140, and a water retaining material in a box 137 made of a ring-shaped insulating material. 141 is formed by an electrode pin or the like (not shown).

The mist discharge pin 138 and the water absorbing pin 139 are formed by mixing and mixing a polyester fiber with a carbon fiber as a conductive material to form a pin shape (rod shape), have water retention property and water absorption property, and have electrical conductivity. The mist discharge pin 138 and the water absorption pin 139 also carry a platinum nano colloid. The platinum nanoparticle colloid can be carried, for example, by immersing the mist discharge pin 138 in a treatment liquid containing a platinum nano colloid and calcining it.

Further, the mist discharge pin 138 and the water absorbing pin 139 are radially arranged at eight intervals formed on the peripheral wall of the casing 137 at equal intervals.

The water absorbing pin 139 is directed substantially straight downward, and the water absorbing pin 139 is longer than the mist releasing pin 138, and the length of all the mist releasing pins 138 is substantially the same. It will be understood from the above that the water absorbing pin 139 is obtained by lengthening one of the mist discharge pins 138.

The conductive sheet 140 is formed, for example, by mixing a polyester fiber with a carbon fiber as a conductive material to form a nonwoven fabric, and has water retention property and conductivity. The conductive sheet 140 is disposed in an annular shape along the inner peripheral surface of the cartridge 37, and is in contact (electrically connected) with the mist discharge pin 138 and the bottom end side of the water absorbing pin 139. Further, although not shown, the tip end of the electrode pin is electrically connected to the conductive sheet 140.

The water-repellent material 141 is formed into a disk shape by, for example, a urethane sponge having excellent water retention properties and water absorption properties, and is tightly housed inside the conductive sheet 140 in the case 137, so that the mist discharge pin 138 and the water absorbing material The pin 139 indirectly contacts the water retaining material 141 via the conductive sheet 140.

Here, the defrosting water receiver 40 and the defrosting water accumulator 56 will be described in detail.

As shown in Fig. 22, the defrosting water receiver 40 is attached to the inner wall of the heat insulating box 2, and is fixed so as to protrude forward from the inside (the inside of the vegetable compartment 4), and the defrosting water accumulator 56 is attached to the refrigerator. The inner wall of the cooler chamber 129 is fixed so as to protrude rearward (in a direction opposite to the inner direction of the vegetable compartment 4). Thus, these defrosting water receptacles 40 are opposite to the protruding direction of the defrosting water accumulator 56.

Further, in order to dispose the defrosting water receiver 40 and the defrosting water accumulator 56, the refrigerating cooler chamber 129 has an expansion in which the space of the arrangement portion is expanded more forward than the other portions. Part 129e.

The expansion portion 129e protrudes further forward than the refrigerating chamber front wall portion 129d, and the defroster water receiver 40 and the defrosting water accumulator 56 are disposed in the expansion portion 129e.

The expansion portion 129e preferably extends from the refrigerating cooler chamber front wall portion 129d toward the partition wall 10. Further, a gap g is provided between the defrosting water accumulator 56 and the inner wall of the heat insulating box 2 to isolate them, in particular, the separation distance is at least the inner wall of the defrosting water accumulator 56 and the heat insulating box 2. The size is not more than the extent to which the water droplets are connected.

Further, both the defrosting water receiver 40 and the defrosting water accumulator 56 are formed of plastic which is an electrically insulating material.

Further, the defrosting water accumulator 56 has a container-shaped water storage portion 56b which is lower than the attachment portion 56a on the rear side of the front attachment portion 56a, and accumulates in the water storage portion 56b as indicated by W The defrosting water dropped by the cooler 24 is refrigerated.

On the other hand, the water absorbing pin 139 of the mist generating unit 136 passes through the upper wall portion 129c of the expanded portion of the refrigerating cooler chamber 129 from the upper side to the lower side (in the refrigerating cooler chamber 129), and the lower end portion is accumulated in the defrosted water. The inside of the water storage portion 56b of the device 56 is located near the bottom.

Here, the expansion unit 129e is provided in the refrigerating cooler chamber 129, and the defrosting water accumulator 56 is disposed in the expansion unit 129e. Therefore, the refrigerating cooler 24 is located at the rear of the vegetable compartment 4 and The mist generating unit 136 is disposed in parallel with the refrigerating cooler chamber front wall portion 129d at the rear of the micro-freezing chamber 14, so that the mist can be efficiently released into the micro-freezing chamber 14, and the micro-freezing chamber 14 can also be enlarged. Volume.

Further, the suction port 132 of the suction duct 131 is located in front of the portion of the refrigerating cooler chamber 129 through which the water absorbing pin 139 penetrates, in particular, directly in front.

In this way, the defrosted water accumulated in the water storage portion 56b of the defrosting water accumulator 56 is sucked by the water absorbing pin 139 and held by the conductive sheet 140, and further sucked and held by the water retaining material 141 from the conductive sheet 140, and The water retaining material 141 is supplied to the mist discharge pin 138 via the conductive sheet 140, respectively.

Therefore, the water absorbing pin 139 functions as a water supply mechanism that supplies the defrosted water accumulated in the defrosting water accumulator 56 to the electrostatic atomization device 135, and the defrosting water accumulator 56 functions as the electrostatic atomization device 135. The water storage unit functions to set the defrosting water accumulator 56 as a water storage unit of the electrostatic atomizing device 135 which is a mist discharge mechanism.

FIG. 21 shows the relationship between the details of the refrigerating cooler 24 and the defrosted water accumulator 56 and the defrosting water receiver 40. The refrigerating cooler 24 has a coolant flow pipe 142 through which a coolant flows in a refrigeration cycle as a main body, and the coolant flow pipe 142 is folded back as shown by each of the folded portions 142a.

At this time, for example, it is formed in a meandering shape in the front and rear two rows (only the previous row is shown in FIG. 21), and a plurality of heat transfer fans 143 are attached to the coolant flow pipe 142. Further, the heat transfer fan 143 is attached to the other straight portion 142b in addition to the folded portion 142a of the coolant flow pipe 142.

The defrosting water accumulator 56 is disposed between the refrigerating cooler 24 and the defrosting water receiver 40 as described above with respect to the refrigerating cooler chamber 129, but is particularly disposed in the refrigerating cooler 24 Between the portion 142a and the defrosting water receiver 40, in particular, the water storage portion 56b is located directly below the folded portion 142a of the refrigerating cooler 24.

Therefore, the defrosting water accumulator 56 is disposed at two sides corresponding to the both side portions of the folded portion 142a of the refrigerating cooler 24, and each of the defrosting water accumulators 56 receives and accumulates from the folded portion 142a by the water storage portion 56b. Falling defrosting water.

Further, below the portion other than the folded portion 142a of the refrigerating cooler 24, that is, below the straight portion 142b to which the heat transfer fan 143 is attached, the defrosting water accumulator 56 is not disposed, and the two defrosting water accumulators are provided. The position of the lower portion (directly below) of the straight portion 142b to which the heat transfer fan 143 is attached is communicated by a communication portion (not shown).

In other words, the defrosting water accumulator 56 is disposed at a position away from the central portion of the refrigerating cooler 24 and below the folded portion 142a, but may be attached to a portion other than the folded portion 142a, that is, the straight portion 142b. The portions of the heat transfer fan 143 are disposed in a slightly overlapping manner.

On the other hand, the defrosting water receiver 40 is located below the entire straight portion 142b of the refrigerating cooler 24 including the folded portion 142a and below the two defrosting water accumulators 56, thereby receiving the cooler for refrigerating 24 drops of defrosting water.

The negative high voltage from the high voltage power supply device is applied to the mist discharge pin 138 via the electrode pin and the conductive sheet 140, respectively, and each mist discharge pin 138 is negatively charged.

However, in the electrostatic atomizing device 135 which is a mist discharge mechanism configured in this manner, a negative high voltage pair is applied in a state where the defrosted water in the defrosting water accumulator 56 is supplied to each of the mist discharge pins 138. Each mist releases the application of the pin 138. At this time, electric charges are concentrated on the tip end portion of each of the mist discharge pins 138, and energy exceeding the surface tension is applied to the water contained in the tip end portion. As a result, the water at the tip end portion of each of the mist release pins 138 is split (Rayleigh split), and is discharged by the tip end portion in a mist form (electrostatic atomization phenomenon).

Therefore, the hydroxyl radical having a strong oxidizing action is released together with the mist from the respective mist releasing pins 138, so that sterilization or deodorization can be performed by the action of hydroxyl radicals.

Next, the action and effect of the above structure will be described.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, the refrigerating blower 30 is driven as described above. Thereby, the air of the refrigerating compartment 3 and the vegetable compartment 4 is circulated on the one hand in contact with the refrigerating cooler 19, and the cooling of the refrigerating compartment 3 and the vegetable compartment 4 is performed as described above.

Further, as the refrigerator compartment 3 and the vegetable compartment 4 are cooled, the frost adheres to the surface of the refrigerating cooler 24, but the frost is used for defrosting when the cooling of the refrigerating compartment 3 and the vegetable compartment 4 is stopped. The heater 70 is heated and melted and removed, and the defrosted water generated after the frost is melted is dropped from the refrigerating cooler 24 and dropped, and is received by the defrosting water accumulator 56 and the defrosting water receiver 40.

Here, the defrosted water received by the defrosting water receiver 40 is not accumulated in the defrosting water receiver 40, but is guided to the defrosting water evaporating dish 28 in the machine room 26 through a water conduit (not shown). The defrosted water received by the defrosting water accumulator 56 is accumulated in the defrosting water accumulator 56.

The defrosted water accumulated in the defrosting water accumulator 56 is supplied to the mist generating unit 136 through the water absorbing pin 139 of the electrostatic atomizing device 135, and is atomized and discharged by the mist generating unit 136 as described above.

In addition, the mist that has been discharged is supplied to the refrigerating compartment 3 and the vegetable compartment 4 by being transported by the air in the refrigerating compartment 3 and the vegetable compartment 4 that are circulated by the cooling of the refrigerating compartment 3 and the vegetable compartment 4 during cooling. In this way, sterilization or deodorization of the refrigerating compartment 3, the vegetable compartment 4, and the micro-freezing compartment 14 can be achieved, and the freshness of the stored product (vegetables, etc.) can be expected to be maintained.

At this time, the defrosted water from the refrigerating cooler 24 is automatically supplied from the defrosting water accumulator 56 to the mist generating unit 136 of the electrostatic atomizing device 135, so that the user's water supply operation to the electrostatic atomizing device 135 can be eliminated.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, the air in the refrigerating compartment 3 and the vegetable compartment 4 that are circulated by the driving of the refrigerating blower 35 become cold air during the contact with the refrigerating cooler 24, and the cold air is supplied. It is supplied to the refrigerating compartment 3 and the vegetable compartment 4.

The water storage unit of the electrostatic atomizing device 135 is a defrosting water accumulator 56 disposed between the defrosting water receiver 40 and the folded portion 142a of the coolant flow pipe 142 of the refrigerating cooler 24, and In the defrosting water accumulator 56, the passage of the cold air in the refrigerating cooler 24 (see the hollow arrow in FIG. 21) is not hindered, so that the flow of the cold air in the refrigerating cooler 24 can be satisfactorily ensured, and the chilled water accumulator 56 can be satisfactorily secured. The cooling performance of the refrigerating compartment 3 and the vegetable compartment 4 is ensured.

Further, the defrosting water accumulator 56 disposed between the defrosting water receiver 40 and the folded portion 142a of the refrigerating cooler 24 is closer to the cooler than the defrosting water receiver 40, and can be at such a short distance Since the defrosted water is supplied to the electrostatic atomization device 135, the water supply to the electrostatic atomization device 135 can be efficiently performed. In addition, in this case, the water absorbing pin 139 which is a water supply means of the electrostatic atomizing device 135 which is a mist discharging means can be made shorter than the defrosting water accumulator 56. Therefore, the water absorbing pin 139 can be made inexpensive.

In the eighth embodiment, the eighth embodiment and the tenth embodiment of the present invention are denoted by the same reference numerals, and the description thereof will be omitted, and only the different portions will be described.

Further, the inclined portion 151 may not be attached to the folded portion 142a, but this may be arbitrary or may be attached thereto.

In this way, the folded portion 142a of the refrigerating cooler 24 is attached with the inclination 151 toward the defrosting water accumulator 56 side (downward), so that the defrosted water of the straight portion 142b or the inclined portion 151 easily flows down the inclined portion 151 and is concentrated.

As a result, the defrosted water is easily dropped from the folded portion 142a, and the amount of defrosted water stored in the defrosting water accumulator 56 can be increased, and the amount of defrosting water supplied to the electrostatic atomizing device 135 can be increased. Let the release of the mist become sufficient. Further, it is preferable that the lowermost portion of the inclination 151 is located above the defrosting water accumulator 56.

The folded portion 142a or the corresponding portion of the coolant flow pipe 42 may be expanded to integrally form the projections 161.

In the embodiment in which the water-removing protrusion 161 is provided in the folded portion 142a of the refrigerating cooler 24, the defrosted water is also easily dropped from the protrusion 161, and the defrosting in the defrosting water accumulator 56 can be increased. The amount of water stored can further increase the amount of defrosting water supplied to the electrostatic atomizing device 135, so that the release of mist can be made sufficient.

Further, the inclined portion 151 of the eighth embodiment can be provided in the folded portion 142a of the refrigerating cooler 24, whereby the defrosted water can be more easily dropped.

Thus, in the embodiment in which the defrosting water receiver 40 is provided with the protruding portion 40a capable of receiving the overflow water from the defrosting water accumulator 56, it is possible to prevent the overflow from the defrosting water accumulator 56 from falling to the defrosting water. The lower portion of the device 40, in particular, is dropped to the portion of the refrigerating blower 35.

Further, the protrusion 40a can be used to block the flow of the air that is to pass through the portion of the folded portion 142a of the refrigerating cooler 24 from below the defrosting water receiver 40, so that the air is cooled as much as possible by the refrigerating cooler 24. Since the portion of the heat-conductive fan 143 having high effect is excellent in cooling efficiency of the air for the refrigerating cooler 24, the cooling efficiency of the refrigerating chamber 3 and the vegetable compartment 4 can be improved.

In addition, either or both of the inclined portion 151 of the eighth embodiment and the protruding portion 161 of the ninth embodiment may be provided in the folded portion 142a of the refrigerating cooler 24.

The defrosting water accumulator 235 has a rectangular container shape as a whole, and the front wall 243 is formed at the same height as the left and right side walls 244, 245. The rear wall 246 is formed with a cutout portion 246a at the upper portion, and the height of the rear wall 246 is formed to be lower than the other three (front, left and right) walls. In the present embodiment, the cutout portion 246a is an overflow portion.

By fixing the attachment portion 243a of the front wall 243 of the defrosting water accumulator 235 to the inner surface of the cold air duct 229, the defrosting water accumulator 235 is fixed by cantilever support. The water storage portion 35a of the defrosting water accumulator 235 receives and accumulates the defrosted water dripped from the refrigerating cooler 24, and gradually stores the defrosted water from the concave portion 235c, when the water level of the defrosted water reaches the upper end of the rear wall 246. The notch portion 246a serves as an overflow portion through which the defrosted water overflows.

The rear wall 246 is provided with a projection 246b whose lower end portion protrudes downward from the rear end portion of the bottom surface portion 235b. The rear end portions (front end portions) of the left and right side walls 244 and 245 are provided with left and right side extension portions 244a and 245a which are formed to protrude rearward (frontward) from the rear wall 246.

In this way, the defrosted water accumulated in the water storage portion 235a of the defrosting water accumulator 235 is sucked by the water absorbing pin 240 and supplied to the mist discharge pin 239 in the same manner as described above.

Therefore, the water absorbing pin 240 functions as a water supply mechanism that supplies the defrosted water accumulated in the defrosting water accumulator 235 to the electrostatic atomizing device 236, and the defrosting water accumulator 235 functions as the electrostatic atomizing device 236. The water storage unit functions to set the defrosting water accumulator 235 to a water storage unit of the electrostatic atomizing device 236 which is a mist discharge mechanism.

Fig. 30 is a view of the defrosted water accumulator 235 and the defrosting water receiver 234 in the cold air duct 229 as seen from above. The defrosting water accumulator 235 protrudes rearward from the front side of the cold air duct 229, and the defrosting water receiver 234 located below the defrosting water accumulator 235 protrudes forward from the rear side of the cold air duct 229. The rear wall 246 of the defrosting water accumulator 235 is located within the range of the defrosting water receiver 234 as viewed from above. Therefore, the notch portion 246a, the protrusion portion 246b of the rear wall 246 of the overflow portion of the defrosting water accumulator 235, and the left and right side extension portions 244a, 245a of the left and right side walls 244, 245 are also located in the defrosting when viewed from above. Within the scope of the water receptacle 34.

Next, the action and effect of the above-described structural embodiment will be described.

As the refrigerator compartment 3 and the vegetable compartment 4 are cooled, the frost adheres to the surface of the refrigerating cooler 24, but when the frost stops the cooling of the refrigerating compartment 3 and the vegetable compartment 4, the frost is removed as described above. The frost is heated and melted and removed by the heater, and the defrosted water generated after the frost is melted is dripped from the refrigerating cooler 24, and is received by the defrosting water accumulator 235 and the defrosting water receiver 234.

Here, the defrosted water received by the defrosting water receiver 234 is not accumulated in the defrosting water receiver 234, but is guided to the defrosting water evaporating dish 28 in the machine room 26 by a water conduit (not shown) and evaporated. However, the defrosted water received by the defrosting water accumulator 235 is accumulated in the defrosting water accumulator 235.
