In the electrostatic atomization device 48 configured in this way, in the state where the water in the water storage container 56 is sucked by the water retention material 55 and supplied to the respective mist discharge pins 57, the negative power from the power supply device 52 is applied to each mist discharge pin 57. of high voltage.

At this time, electric charge concentrates on the front-end part of each mist discharge pin 57, and the energy (energy) exceeding surface tension is given to the water contained in this front-end part. As a result, the water at the tip of each mist releasing pin 57 splits (Rayleigh fission), and is released in the form of a fine mist from the tip (electrostatic atomization phenomenon).

Here, the water particles emitted in mist form are negatively charged, and contain hydroxyl radicals (hydroxyl radicals), which are antibacterial components and deodorizing components generated by the energy.

Therefore, hydroxyl radicals having a strong oxidizing effect are released together with the mist from each mist releasing pin 57, and sterilization or deodorization can be performed by the action of the hydroxyl radicals. At this time, the counter electrode corresponding to the negatively charged mist discharge pin 57 is not provided.

Therefore, the discharge itself from the mist discharge pin 57 becomes very smooth, and no corona discharge will be generated between the discharge electrode and the opposite electrode, thereby suppressing harmful gases (ozone, or ozone causing the formation of ions in the air). Nitrogen oxides produced by the oxidation of nitrogen, nitrous acid, nitric acid, etc.)

Here, the mist releasing pin 57 (mist releasing part 50) can be referred to as a sterilizing component releasing mechanism (also a deodorant component releasing mechanism) that emits a bactericidal component (also a deodorant component) of hydroxyl radicals. The device 48 can be called a degerming component generating means (deodorizing component generating means).

The mist outlet 67 for the vegetable compartment communicates with the communication port 75, and a part of the mist in the dedicated conduit 45 for mist is also supplied to the vegetable compartment through the mist outlet 67 for the vegetable compartment, the communication port 75, the V conduit 76, and the ventilation port 77. 4 (refer to arrow C2 in Figure 10).

At this time, the total opening area S1 of the mist blowing outlet 67 for vegetable compartments is set smaller than the total opening area S2 of the mist blowing outlet 65 for micro freezing compartments (S1<S2).

And in Fig. 4, the distance L1 between the mist cooling air supply port 62 and the vegetable compartment mist blowing port 67 that blows cold air into the mist dedicated duct 45 is set to be greater than the mist cooling air supply port 62 and micro Distance L2 (L1>L2) between the mist blowing outlets 65 for freezer compartments.

Furthermore, as shown in FIG. 11 , on the duct constituting member 46 of the dedicated mist duct 45 , a path narrowing wall 67 a is provided above the upstream side of the mist outlet 67 for vegetable compartment. The path narrowing wall 67a is in a form that narrows the path 67b through which the air flowing through the dedicated mist duct 45 flows to the mist outlet 67 for vegetable compartments.

On the upper portion of the mist-use duct 45, a cold air supply port 68 for a micro freezing chamber is provided above the mist discharge part 50 (see FIG. 4, FIG. 6, FIG. 8). As shown in FIGS. 6 , 8 and 9 , the cold air supply port 68 for the micro-freezing chamber is in the shape of a forward-facing cylinder that protrudes farther forward from the front surface portion of the duct constituting member 46 , and is located at the rear of the micro-freezing box 18 . The upper end of the wall is further upward (refer to FIG. 9 ).

The cold air supply port 68 for the micro-freezing chamber penetrates the heat insulating material 38 at the rear and communicates with the cooler chamber 36 for refrigeration, and the front part penetrates the dedicated mist duct 45 and communicates with the micro-freezing chamber 14 .

Therefore, a part of the cold air in the cooler chamber 36 for refrigeration is directly supplied to the slightly freezing chamber 14 through the cold air supply port 68 for the slightly freezing chamber (refer to FIGS. The temperature lower than the refrigerator compartment 3 and the vegetable compartment 4 is 0°C to 1°C. Furthermore, the heat insulating material 38 also serves as an insulating means between the cooler 24 for refrigeration and the mist discharge|release part 50.

Next, the action of the above structure will be described. As mentioned above, when cooling the refrigerating room 3 and the vegetable room 4, the cold air cooled by the refrigerating cooler 24 is mainly passed through as shown by the hollow arrow in FIG. The cold air supply duct 37 is supplied to the refrigerator compartment 3 from a plurality of cold air supply ports 39, and a part of the cold air is directly supplied to the micro freezing chamber 14 from the cold air supply port 68 of the micro freezing chamber (with reference to the arrows in Fig. 6 and Fig. 8 ). A2).

After the cold air supplied to the refrigerator compartment 3 and the micro-freezer compartment 14 contributes to the cooling of the stored items such as food, as described above, it flows out from the vent holes 74a, 74b to the ventilator as indicated by the arrow C1 in FIG. 9 . Road 73, and flow through the air passage 73 toward the left and right, and then supply to the vegetable compartment 4 through the left and right outer surfaces of the upper box 12 of the vegetable compartment 4, and a part of the cold air in the micro-freezing compartment 14 is as follows: As indicated by the arrow C2 in FIG. 10 , it passes through the V duct 76 from the communicating port 75 and is supplied into the vegetable compartment 4 from the air vent 77 .

The cold air supplied into vegetable compartment 4 contributes to cooling of vegetables and other stored items, and then is sucked into refrigeration blower 35 through suction port 43, and is cooled again by refrigeration cooler 24, and the cycle repeats.

And when cooling the refrigerator compartment 3 and the vegetable compartment 4, a part of the cool air in the cooler compartment 36 for refrigeration is supplied from the cool air supply port 62 for mist to the dedicated duct 45 for mist, as indicated by arrow A1 in FIG. 7 . Inside. The cold air supplied into the dedicated mist duct 45 collides with the inner surface of the duct constituent member 46 to form convective flow in the dedicated mist duct 45 to diffuse.

At this time, when the electrostatic atomization device 48 is driven, a fine mist containing hydroxyl radicals as described above is released from the plurality of mist discharge pins 57 in the mist generating unit 51 .

A part of the mist emitted from the mist releasing pin 57 is shown in arrow B1 of FIG. The supply port 39 supplies into the refrigerator compartment 3 .

And, as shown in Fig. 4 and the arrow B2 of Fig. 7, a part of the mist emitted from the mist releasing pin 57 is supplied from the mist outlet 65 to the micro-freezing chamber 14, especially in the micro-freezing box 18, and As shown by arrow B3 in FIG. 4 , it is also supplied into the egg box 15 from the egg box mist outlet 66 .

Furthermore, a part of the mist released from the mist discharge pin 57 is also supplied into the vegetable compartment 4 from the mist outlet 67 for vegetable compartment at the lower right through the communication port 75 , the V duct 76 , and the ventilation port 77 .

Therefore, in this embodiment, the mist generated in the dedicated mist duct 45 can be supplied to a plurality of supply targets such as the refrigerator compartment 3, the micro-freezing compartment 14, the egg box 15, and the vegetable compartment 4, and it is expected that the mist of these supply targets will be improved. Antibacterial and deodorizing effects can also be expected for moisturizing and freshness preservation of vegetables and the like.

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

Owing to having adopted following structure, promptly, the electrostatic atomizing device 48 that constitutes the antibacterial component generation mechanism (mist releasing mechanism) is arranged on the inner part of micro-freezing chamber 14, the antibacterial component that will be produced by this electrostatic atomizing device 48 The mist of (hydroxyl radicals) is supplied to the micro-freezing compartment 14, so that the micro-freezing compartment 14 can be cooled to a temperature lower than that of the refrigerator compartment 3 and the vegetable compartment 4 by utilizing the cool air supplied from the cool air supply port 68 for the micro-freeze compartment. The temperature of the micro-freezing compartment 14 can be maintained at about 0° C., and the micro-freezing compartment 14 for storing meat or fish can be easily sterilized or deodorized, and moisturizing or freshness can also be performed.

Then, part of the air (cold air) circulated by the refrigeration blower 35 after passing through the refrigeration cooler 24 is supplied from the mist cold air supply port 62 to the mist discharge unit 50 of the electrostatic atomization device 48 ( FIG. 7 ).

At this time, the mist emitted from the mist emitting part 50 is blown out from the mist blowing port 65 for the micro freezing chamber into the micro freezing chamber 14 together with the air (cold air) supplied to the mist emitting part 50, and is blown out from the mist blowing port 67 for the vegetable compartment. The air is blown into the vegetable compartment 4 through the communicating port 44 .

Here, the opening area S1 of the mist blowing outlet 67 for the vegetable compartment is set to be smaller than the opening area S2 of the mist blowing outlet 65 for the micro-freezing compartment, so the air volume ( The amount of cold air) is less than the air volume (amount of cold air) blown from the mist outlet 65 for the micro freezing compartment into the micro freezing compartment 14 .

Therefore, the air volume (the amount of cold air) blown from the vegetable compartment mist outlet 67 to the vegetable compartment 4 side can be suppressed, and the vegetable compartment 4 can be prevented from being overcooled by the cold air passing through the refrigeration cooler 24 .

Since the distance L1 between the cool air supply port 62 for mist and the mist blowout port 67 for vegetable compartments that supplies the air that has passed through the cooler 24 for refrigeration to the mist discharge unit 50 is configured to be longer than the cool air supply port 62 for mist and the micro The distance L2 between the mist blowing outlets 65 for the freezing room, therefore, although the cold air supplied from the cold air supply port 62 for the mist to the special conduit 45 for the mist is easy to flow to the mist blowing outlet 65 for the micro freezing room, it is more difficult to flow to the mist blowing outlet 65 than the cold room. The vegetable compartment mist is blown out to the side of the outlet 67, and furthermore, it is difficult for cool air to flow to the vegetable compartment 4 side. Thereby, it is also possible to prevent the vegetable compartment 4 from being too cold due to cold air.

The mist discharge part 50 is arrange|positioned between the cool air supply port 62 for mist, and the mist blowing port 65 for vegetable compartments. Thereby, the mist discharged|emitted from the mist discharge|release part 50 flows easily to the mist outlet 65 for vegetable compartments, and mist can also be supplied to the vegetable compartment 4 favorably.

Owing to adopting the structure that the mist containing the degerming component produced by the electrostatic atomization device 48 is also supplied to the vegetable compartment 4 adjacent to the micro freezing compartment 14, it is also possible to achieve degerming or deodorization of the vegetable compartment 4, and also It is possible to keep moisture or freshness of vegetables and the like.

Since the following structure is adopted, that is, a notch 18b is formed on the rear upper part of the micro-freeze box 18, and the mist containing the sterilization component blown out from the mist outlet 65 for the micro-freeze chamber is supplied to the micro-freeze box 18 from the notch 18b. Therefore, the mist containing the antibacterial component blown out from the mist outlet 65 for the micro freezing compartment can be efficiently supplied into the micro freezing box 18 .

And since the mist outlet 65 for a micro freezing compartment is cylindrical, the mist containing a microbe removal component can be supplied satisfactorily into the micro freezing box 18 from the mist outlet 65 for a micro freezing compartment.

Owing to adopted following structure, promptly, the upper part of micro-freezing chamber 14 is blocked by the loading plate 70 that constitutes top plate part, and the front surface is blocked by the front surface wall 18a of micro-freezing box 18, so when micro-freezing box 18 is received In the state in the micro-freezing chamber 14, the mist containing the antibacterial components supplied to the micro-freezing chamber 14 is difficult to leak to the outside, so that the effect of the mist containing the anti-bacterial components can be more effectively brought into play in the micro-freezing chamber 14. effect.

In micro-freezing chamber 14, be provided with vent 74a and the communication port 75 that become the outlet of the air of micro-freezing chamber 14, the air in micro-freezing chamber 14 flows out to micro-freezing chamber 14 from vent 74a and communication port 75 respectively. Therefore, the supply of the mist containing the microbe-eliminating component into the micro-freezing compartment 14 from the mist outlet 65 for the micro-freezing compartment can be easily received.

The following structure is adopted, that is, the communication port 75 connecting the micro-freezing compartment 14 and the vegetable compartment 4 is provided at the bottom of the micro-freezing compartment 14, and the micro-freezing box 18 does not block the communicating port 75 . Thereby, even in the state in which the micro-freeze box 18 is accommodated in the micro-freeze compartment 14, the communicating port 75 can be ensured, and the flow of the air containing the mist passing through this communicating port 75 can be ensured.

Since the following structure is adopted, that is, the electrostatic atomization device 48 has a water storage container 56 that receives and stores the defrosting water of the cooler 24 for refrigeration, atomizes the water in the water storage container 56, and The mist of the bacterial component is supplied to the micro-freezing chamber 14. Therefore, as described above, the mist containing the micro-freezing component (hydroxyl radical) can be supplied to the micro-freezing chamber 14, so that the micro-freezing chamber 14 can be sterilized or deodorized. And also can realize moisturizing or keeping fresh.

Moreover, the water used in the electrostatic atomization device 48 is the defrosted water that utilizes the refrigerating cooler 24 stored in the water storage container 56, so the water supply to the water storage container 56 can be automatically performed, thereby saving the user (user) work to perform water supply.

Since the cooler 24 for refrigeration is arranged behind the micro-freezing chamber 14 , the defrosted water of the cooler 24 for refrigeration near the micro-freezing chamber 14 can be used as the water used in the electrostatic atomization device 48 .

The freezing refrigerator of the present embodiment employs a double evaporator (evaporator) type refrigeration cycle including two coolers, ie, a cooling cooler 24 and a freezing cooler 25 .

Here, the peripheral temperature of the cooling cooler 25 of the freezing refrigerator adopting the refrigerating cycle of the double evaporator system or the peripheral temperature of the cooler of the freezing refrigerator of the single evaporator system will be affected by defrosting during defrosting. The temperature becomes positive when heated by the frost heater, but the temperature is always kept below -20°C except during defrosting.

Assuming that a water storage container is provided under these coolers, even if the water storage container is used to receive and store defrosted water during defrosting of the coolers, the water in the water storage container is likely to freeze and is difficult to melt.

Therefore, there is a problem that it is difficult to stably supply water to the mist discharge part 50 .

Regarding this point, in this embodiment, in the double evaporator type freezing refrigerator provided with two coolers, the cooler 24 for refrigeration and the cooler 25 for freezing, the water storage container 56 is installed in the cooler for refrigeration. The structure below the device 24.

In the double evaporator type freezing refrigerator, although the peripheral temperature of the cooler 24 for refrigeration becomes a negative (minus) temperature during the cooling operation of the cooler 24 for refrigeration, it is still much higher than the temperature of the cooler 25 for freezing. , And, in the cooling operation of the cooler 25 for freezing (cooling of the storage room in the freezing temperature range) or during the stoppage of the compressor 27, the air circulation of the air blower 35 for refrigeration will rise to the level close to the refrigerator compartment 3. The temperature is around +3°C.

Therefore, the water in the water storage container 56 provided below the cooler 24 for refrigeration hardly freezes, and even if it freezes, it is easy to melt, so that the water can be stably supplied to the mist discharge unit 50 .

The mist discharge unit 50 of the electrostatic atomization device 48 is constituted by a plurality of mist discharge pins (protrusions) 57 protruding in different directions. With this structure, unlike the case where the projection direction of the mist generating protrusion is only unidirectional, 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 discharge part 50 is configured to extend upward and downward in opposite directions by sandwiching the horizontal part 53a of the water supply part 53 with the mist discharge pin (protrusion) 57, so that the mist can also be discharged in opposite directions upward and downward. The supply range of mist can be widened.

Further, the horizontal portion 53a of the water supply unit 53 and the mist release pins 57 are arranged along the front wall 36a of the cooler chamber 36 for refrigeration in the cold air duct 34 so as to be parallel to the front wall 36a. This enables thinning in the front-back direction. Compactness can be achieved by arranging the mist release pin (protrusion) 57 in two stages up and down.

The mist emitting part 50 adopts a structure in which a plurality of the mist emitting pins (protrusions) 57 are arranged in a row, so that the amount of mist released can be increased, thereby further widening the supply range of the mist, and furthermore, a thin profile can be realized. change.

The water supply unit 53 has a curved portion 53c, a water storage container 56 for storing water is provided below the curved portion 53c, and the water stored in the water storage container 56 can be supplied to the curved portion 53c. Thereby, the water in the water storage container 56 can be supplied to the mist discharge pin 57 via the bent part 53c.

The power supply device 52 is disposed on the opposite side of the curved portion 53c with the mist emission portion 50 interposed therebetween. Thereby, the power supply unit 52 can be further separated from the water storage container 56 .

Furthermore, by arranging the power supply device 52 and the mist generating unit 51 along the front wall 36a of the cooler compartment 36 for refrigeration in the cold air duct 34 in parallel with the front wall 36a, electrostatic atomization can be realized. Thinning of the device 48 in the depth direction.

The mist discharge pin (projection) 57 in the mist discharge part 50 of the electrostatic atomization device 48 is arrange|positioned so that it may run along the cool air duct 34. As shown in FIG. Thereby, the depth dimension of the front-back direction of the electrostatic atomization device 48 can be suppressed, and thickness reduction can be achieved. Along with this, the reduction of the internal volume of a refrigerator can be suppressed.

In front of the cool air duct 34 is provided a mist cool air supply port 62 for supplying cool air into the mist dedicated duct 45 , and the mist discharge unit 50 of the electrostatic atomization device 48 is arranged in front of the cool air duct 34 .

Thereby, the mist emitted from the mist emission part 50 can be diffused far away by the cooling air supplied from the cool air supply port 62 for mist into the dedicated duct 45 for mist.

The cold air supply port 62 for mist and the mist discharge part 50 (mist discharge pin 57) are arranged in a position deviated from the left and right in a manner different from the opposing position (not directly facing each other). The cooling air supplied into the dedicated mist duct 45 does not directly blow to the mist releasing part 50 (mist releasing pin 57).

Thereby, the phenomenon that the mist discharge pin 57 directly receives the cooling air from the cool air supply port 62 for mist and dries can be suppressed.

In the refrigerator body 1, the mist dedicated duct 45 containing the electrostatic atomization device 48 having the mist emitting part 50 is included, and in the mist dedicated duct 45, a supply destination of the mist generated by the mist emitting part 50 is provided. Different multiple fog blowing outlets.

The plurality of mist outlets specifically refer to the mist outlet 63a for the refrigerator, the mist outlet 65 for the freezer, the mist outlet 66 for the egg box, and the mist outlet 67 for the vegetable room.

As a result, the mist generated in the dedicated mist duct 45 can be supplied to the four supply destinations of the refrigerator 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, so that the mist can be expanded. range of effects.

The microfreeze compartment 14, the egg box 15, and the vegetable compartment 4 among the mist supply destinations have the microfreeze box 18, the egg box 15, and the vegetable box (the lower box 11 and the upper box 12), respectively, and the mist can be supplied to these boxes satisfactorily. Inside.

At this time, a plurality of mist blowing outlets (the mist blowing outlet 63a for the refrigerator compartment, the mist blowing outlet 65 for the slightly freezing room, the mist blowing outlet 66 for the egg box, and the mist blowing outlet 67 for the vegetable compartment) are arranged in the mist emitting part 50. Since it is the periphery of the center, the mist released from the mist discharge part 50 can be supplied to each mist outlet well.

The mist generating unit 51 has a mist releasing pin (protrusion) 57, a plurality of mist blowing outlets (the mist blowing outlet 63a for the refrigerator compartment, the mist blowing outlet 65 for the micro freezing room, and the mist blowing outlet 66 for the egg box) of the dedicated conduit 45 for the mist. and the vegetable compartment mist outlet 67) are arranged in a position different from the position facing the mist release pin 57 (a position not directly facing each other), so even if a finger or a foreign object is inserted from the mist outlet In the conduit 45, they can also be prevented from directly contacting the mist discharge pin 57, thereby ensuring safety.

Furthermore, since the duct constituting member 46 forming the dedicated duct 45 for mist is detachable, maintenance of the mist generating unit 51 and the like can be easily performed.

The cold air duct 34 has a front wall 36a (first protrusion) in which the cooler compartment 36 for refrigeration of the cooler 24 for refrigeration is arranged, and a lower protrusion 36c ( 2nd protruding part), the cool air supply port 62 for mist which supplies wind (cooling air) into the dedicated duct 45 for mist is provided in the front part wall 36a which becomes a 1st protruding part.

According to this structure, the water storage container 56 is arranged in the cool air duct 34, and the cold air (wind) supplied from the mist cool air supply port 62 into the mist dedicated duct 45 is not supplied to the water storage container 56, so the inside of the water storage container 56 The stored water is difficult to evaporate, so that water for mist can be well secured.

The lower protruding portion 36c serving as the second protruding portion is provided so as to protrude farther forward toward the front wall 36a serving as the first protruding portion. The water retaining material 55 that is transferred to the mist emitting part 50 extends from the lower protrusion 36c into the mist dedicated duct 45 outside the cool air duct 34, and the mist emitting part 50 is arranged in front of the front wall 36a.

According to this structure, the cool air supply port 62 for mist that supplies wind (cool air) into the duct 45 dedicated for mist is formed on the front wall 36a, and the wind supplied to the duct 45 dedicated for mist from the cool air supply port 62 for mist is formed. Can not blow to the bottom of the water-retaining material 55 that absorbs the water of the water storage container 56, therefore, especially can prevent: the bottom of the water-retaining material 55 becomes dry because of the wind from the mist cold air supply port 62, thereby can make the water storage container 56 The water is well supplied to the mist discharge unit 50 . Furthermore, since the water retaining material 55 is covered by the case 54, even if the case 54 receives wind, the water retaining material 55 is less likely to dry out.

(second embodiment)

Fig. 12 shows a second embodiment. In this second embodiment, the structure of the mist generating unit 86 in the electrostatic atomization device 85 constituting the microbe-eliminating component generating means is different from that of the first embodiment.

The mist releasing part 87 is comprised from the several mist releasing pins 57 which respectively comprise a protrusion. The mist discharge pins 57 are radially provided on the outer peripheral portion of the circular portion 88a.

Therefore, the mist discharge part 87 is comprised with the some mist discharge pin 57 (protrusion part) which protruded in different directions. The bottom end of each mist release pin 57 penetrates the case 89 and contacts the water retaining material 90 .

Each mist release pin 57 is also arranged along the front wall 36 a of the cooler compartment 36 for refrigeration in the cold air duct 34 so as to be parallel to the front wall 36 a.

In the left part of the circular part 88a in the water supply part 88, a protruding part 88c protruding to the left side is provided, and the power receiving pin 58 is provided in a state protruding to the left on the protruding part 88c. The power receiving pin 58 is connected to the power supply terminal 61 on the side of the power supply device 52 .

In this structure, the water stored in the water storage container 56 is sucked by the water retention material 90 by capillary action, and supplied to each mist discharge pin 57 . Then, a negative high voltage from power supply unit 52 is applied to each mist discharge pin 57 via water content of water retention material 90 from power receiving pin 58 , and based on this, fine mist is released from each mist discharge pin 57 .

The mist emitted from each mist discharge pin 57 is the same as the first embodiment, through a plurality of mist outlets (the mist outlet 63a for the refrigerator compartment, the mist outlet 65 for the micro freezing room, the mist outlet 66 and the mist outlet for the egg box). The vegetable compartment mist outlet (67) is supplied to a plurality of supply destinations such as the refrigerator compartment 3, the micro-freezing compartment 14, the egg box 15, and the vegetable compartment 4.

In such a second embodiment, since the mist releasing pins 57 are arranged radially, there is an advantage that mist can be released in more directions than in the case of the first embodiment.

(third embodiment)

Fig. 13 shows a third embodiment. This third embodiment differs from the first embodiment in the following points.

On the passage narrowing wall 67a which narrows the upstream passage 67b of the mist blowing outlet 67 for vegetable compartments, the wind direction board 81 is provided in the fixed state. The wind direction plate 81 further narrows the passage 67b.

By providing the wind direction plate 81, the amount of cold air blown from the vegetable compartment mist outlet 67 to the vegetable compartment 4 can be further reduced, thereby preventing the vegetable compartment 4 from being overcooled.

(fourth embodiment)

Fig. 14 shows a fourth embodiment. This fourth embodiment differs from the third embodiment in the following points.

A wind direction plate 82 is rotatably provided in the passage narrowing wall 67a instead of the wind direction plate 81 in a fixed state. The opening area of the passage 67b can be changed by the turning position of the wind direction plate 82 .

The rotational position of the wind direction plate 82 is preferably controlled by a motor (not shown). Thereby, the same effect as that of the third embodiment can be obtained.

(fifth embodiment)

Fig. 15 shows a fifth embodiment. This fifth embodiment differs from the first embodiment in the following points.

The heater 83 which consists of an electric heater is provided in the passage 67b above the mist outlet 67 for vegetable compartments. By heating the air (cold air) passing through the passage 67 b by the heater 83 , the temperature of the air blown out from the mist outlet 67 for vegetable compartment can be increased, and overcooling of the vegetable compartment 4 can be more reliably prevented.

(sixth embodiment)

Fig. 16 shows a sixth embodiment. This sixth embodiment differs from the first embodiment in the following points.

In the partition plate 10 which partitions between the refrigerator compartment 3 and the vegetable compartment 4, the extension duct 185 (duct) extended to the front-back direction (left-right direction in FIG. 16) is provided. The extension duct 185 is two upper and lower sections of the upper duct 185a and the lower duct 185b, and the upper duct 185a and the lower duct 185b communicate with each other through the communicating portion 185c at the front.

Among them, the rear upper portion of the upper duct 185 a communicates with the mist outlet 67 for vegetable compartments through the communication port 75 . On the lower surface of the lower duct 185b, a plurality of air outlets 186 opening to the upper portion of the vegetable compartment 4 are provided.

In the above structure, the air and mist convected in the dedicated mist duct 45 are supplied to the upper duct 185 a of the extension duct 185 through the mist outlet 67 for vegetable compartment and the communication port 75 . The air and mist supplied to the upper duct 185a flow forward in the upper duct 185a as shown by the arrow C in FIG. Then, the air is blown out into the vegetable compartment 4 from a plurality of outlets 186 .

In the above-described embodiment, the temperature of the air and mist blown out from the vegetable compartment mist outlet 67 gradually increases while passing through the extension duct 185, so that the vegetable compartment 4 is supplied with relatively high-temperature air, thereby enabling Overcooling of the vegetable compartment 4 is prevented.

(Other implementations)

The antimicrobial component generation mechanism is not limited to the above-mentioned electrostatic atomization device. For example, a structure may be adopted in which ions are generated by applying a high voltage to the discharge electrode, and the ions are combined with moisture in the air. The resulting components are released as antibacterial components. Furthermore, a structure may be employed in which ozone is generated by corona discharge or the like, and ozone is released as a microbe-eliminating component.

Furthermore, an ultrasonic atomization device may be used, which atomizes the water stored in the water storage part and discharges the mist by ultrasonic vibration of the ultrasonic vibration element. Moreover, the mist blowing port 63a for refrigerator compartments and the mist blowing port 66 for egg boxes may not be provided as a mist blowing port for blowing off the mist discharged|emitted from a mist releasing means.

As described above, according to the refrigerator of the present embodiment, the following structure is adopted, that is, the antibacterial component generating mechanism that generates mist is provided in the inner part of the microfreezing chamber, and the hydroxyl radicals generated by the antibacterial component generating mechanism Since a micro-freezing component such as ozone or ozone is supplied to the micro-freezing compartment, the micro-freezing compartment for storing meat, fish, etc. can be easily sterilized or deodorized.

And, according to the refrigerator of the present embodiment, in the refrigerator in which the mist released from the mist discharge part is supplied to the microfreezing compartment and the vegetable compartment by utilizing the cold air after passing through the cooler, the opening area of the mist blowing outlet for the vegetable compartment is set It is smaller than the opening area of the mist blowing outlet for the micro-freezing chamber.

Thereby, the air volume (amount of cold air) blown from the mist outlet for vegetable compartment to the vegetable compartment side becomes smaller than the air volume (amount of cool air) blown into the micro freezing chamber from the mist outlet for micro freezing compartment.

Therefore, the air volume (the amount of cool air) blown from the vegetable compartment mist outlet to the vegetable compartment 4 side can be suppressed, and the vegetable compartment can be prevented from being overcooled by the cool air passing through the cooler.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this field Those skilled in the art, without departing from the scope of the technical solution of the present invention, may use the structure and technical content disclosed above to make some changes or modifications to equivalent embodiments with equivalent changes, but any content that does not depart from the technical solution of the present invention, Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
