In addition, at least one side of the reservoir space 121 is provided with a flow path guide 130 for guiding the water stored in the reservoir space 121 to be moved to the heater 150. The flow guide 130 is formed to protrude upward from a bottom of the lower case 101 by a predetermined height. The size of the reservoir space 121 may be defined by the flow path guide 130.

In detail, the flow path guide 130 includes a first guide 131 extending in one direction and a second guide 132 extending in the other direction from the first guide 131. The first guide 131 and the second guide 132 may be integrally formed. In this case, the flow guide 130 has a shape bent in a predetermined direction.

In addition, a water outlet 134 is formed between one end of the first guide 131 and the first wall surface 101a of the lower case 101 to allow the water of the reservoir space 121 to flow out. That is, an opening through which water moves may be formed between the first guide 131 and the first wall surface 101a.

On the other hand, one side of the first guide 131, the outdoor air communication unit 200 is provided so that the reservoir space 121 communicates with the outside of the reservoir 120.

The outside air communicating with the reservoir 120 may be introduced into the water tank 110 while water is supplied from the water tank 110 to the reservoir 120. When the inside of the reservoir 120 is sealed, it is limited that water is introduced from the water tank 110 by the vacuum pressure. Therefore, the reservoir 120, the outside air communicates with the atmospheric pressure needs to be maintained.

In detail, the outside air communication unit 200, the outside air tube 210, the outside air is moved from the outside, the tube connection portion 220 is coupled to the outside air tube 210 and guides the outside air to flow into the reservoir 120 And a float 240 provided below the tube connecting portion 220 and preventing the water of the reservoir 120 from flowing back to the outside. An external air discharge unit 250 coupled to the 220 and a sealing unit 225 for sealing between the tube connection unit 220 and the external air discharge unit 250 are included.

The outside air tube 210 flows outside air introduced through the supply hole 193 (see FIG. 11). In addition, the outside air tube 210 is formed to be bent in an approximately "┏" shape, the end of the outside air tube 210 is formed with a tube end 211 is coupled to the tube connecting portion 220.

The tube connecting portion 220 is formed to be bent in a substantially "┓" shape, one end of the tube connecting portion 220 is formed with a connecting end 221 is coupled to the tube end 211. The outside air flowing in the outside air tube 210 may be moved downward through the tube connection part 220.

For convenience of description, the outside air tube 210 and the tube connection portion 220 are collectively referred to as "outside air inlet".

The outside air discharge part 250 includes a receiving space 252 formed to be recessed downward, and a first discharge hole 254 formed in the receiving space 252 to allow outside air to be discharged from the outside air discharge part 250. ) And a plurality of second discharge holes 258.

The first discharge hole 254 is formed at the bottom of the accommodation space 252, and the second discharge hole 258 is formed around the side surface of the accommodation space 252. The outside air moved from the outside air tube 210 may be moved to the reservoir 120 through the first and second discharge holes 254 and 258.

The accommodation space 252 has a conical shape whose end is cut so that the float 240 can be accommodated. In addition, the float 240 has a shape corresponding to the accommodation space 252.

In addition, the outside air outlet 250 is provided with a plurality of support ribs 255 for supporting the lower side of the float 240 while the float 240 is accommodated in the outside air outlet 250. In a state in which the float 240 is supported by the support rib 255, the lower end of the float 240 may be spaced apart from the first discharge hole 254. In addition, the outside air flows through the spaced space and may be discharged to the outside of the outside air discharge unit 250.

One side of the outside air discharge unit 250 is provided with a flow path forming unit 103 to move the outside air discharged from the first and second discharge holes 254 and 258. An air flow path 216 is formed inside the flow path forming part 103.

The float 240 is provided to be movable between the outside air discharge unit 250 and the tube connection unit 220. As shown in FIG. 6, when the nozzle body 10 is in a normal position, the float 240 is arranged to be accommodated in the accommodation space 252, but when the nozzle body 10 is turned upside down. The float 240 is disposed to be in close contact with the lower side of the tube connecting portion 220. Detailed description thereof will be described later with reference to the accompanying drawings.

In addition, the steam generator 100 is provided with a blocking wall 230 extending from the outside air discharge part 250 and forming one side wall of the air flow path 216. The blocking wall 230 may be formed to be spaced apart from the first guide 131 by a predetermined distance, and may extend substantially parallel to the direction in which the first guide 131 extends.

Between the first guide 131 and the blocking wall 230, a water flow path 136 is formed in which water in the reservoir 120 is moved to the heating part 150. The water flow path 136 may be formed along the outer sides of the first guide 131 and the second guide 132.

In detail, the water stored in the reservoir 120 is moved in the a direction (the first direction) along the first wall surface 101a. Here, the flow path formed along the a direction is referred to as "first flow path". In addition, the flow of water flowing along the first flow path may have a direction opposite to the flow direction of water flowing through the connection flow path 180.

The water moved along the first flow path is bent and then moved in the b direction (second direction) along the space between the first guide 131 and the blocking wall 230. Here, the flow path formed along the b direction is referred to as "second flow path". In addition, the flow of water flowing along the second flow path may form a direction perpendicular to the flow direction of water flowing through the connection flow path 180.

The water moved along the second flow path is bent and then moved in the c direction (third direction) along the space between the second guide 132 and the second wall surface 101b. Here, the flow path formed along the c direction is referred to as "third flow path". Water passing through the third flow path may flow into the heating part 150 through the connection flow path 180.

In summary, the water flowing out of the reservoir space 121 may change in two directions, that is, at least one time, until the water flows into the heating part 150.

As described above, the water stored in the reservoir 120 has a flow that is bent in a plurality of directions before entering the connection passage 180. That is, the water stored in the reservoir space 121 does not flow out directly toward the heating part 150, but is bent out in various directions by the flow guide 130 so that only a small amount of water flows out of the heating part 150. ) Can be introduced into. In addition, even when the nozzle 1 is inclined toward the heating part 150, the water of the water storage part 124 does not flow into the heating part 150 at a time.

As a result, since only a small amount of water stored in the reservoir 120 flows into the heating unit 150, the steam generation time in the heating unit 150 may be shortened.

In addition, even if the water fluctuates while the nozzle 1 is shaken or upside down, the flow path guide 130 may act as a barrier to prevent leakage of water to the outside of the nozzle.

Although the first and second guides 131 and 132 are included in the flow guide 130 in the drawing, alternatively, a larger number of guides may be included. The guides 131 and 132 may be arranged not only in a direction perpendicular to each other but also at various angles.

On the other hand, since the outdoor communication unit 200 and the reservoir 120 are partitioned from each other by the blocking wall 230, in the process of the water of the reservoir 120 is moved in the a direction and b direction, the The movement to the outside air communication unit 200 side can be prevented.

Therefore, even if the nozzle is shaken or upside down, the water of the reservoir is less likely to be moved into the outside air communication unit 200, that is, the outside air outlet 250. As a result, the outflow of water to the outside can be minimized.

In addition, the connection flow path 180 may be inclined downward from the reservoir 120 toward the heating part 150, whereby water may be easily flowed to the heating part 150 side. .

In addition, an air flow path 216 through which air flows is formed between the blocking wall 230 and one edge of the lower case 101 (f direction). In addition, an opening end 235 is formed between one end of the blocking wall 230 and the second wall surface 101b of the lower case 101 to form a flow space of air. Air passing through the external air communication unit 200 may flow toward the storage space 121 through the air flow path 216 and the opening end 235.

Here, the second wall surface 101b is formed at a position facing the first wall surface 101a. That is, since the water outlet 134 and the opening end 235 are formed adjacent to the facing surfaces of the lower case 101, water flowing out through the water outlet 134 is the opening end 235. It becomes less likely to flow into the air flow path 216 directly through).

In summary, the water flow passage 136 and the air flow passage 216 may be divided around the blocking wall 230. In addition, the water flowing out of the reservoir 120 is blocked by the blocking wall 230 and cannot be moved to the air flow path 216. Accordingly, even when the nozzle is shaken or flipped, the external air communication unit 200 It will be less likely to overflow to the side.

In addition, the upper case 102 is formed with a water inlet 104 to allow water to flow from the water tank 110 to the storage space 121 side. Water in the water tank 110 is introduced into the reservoir space 121 through the water inlet 104.

The heater 150 includes a heater 151 for generating heat and a steam discharger 155 for discharging steam generated by the heater 151. The heater 151 may include a sheath heater, a PTC heater, a ceramic heater, and the like. At least a portion of the heater 151 is accommodated between the lower case 101 and the upper case 102, and the other portion protrudes out of the upper and lower cases 101 and 102.

Above the protruding portion of the heater 151, a temperature sensor 154 is provided to sense the amount of heat generated by the heater 151. The temperature sensor 154 has a sensor terminal portion 159, and a sensor fixing portion 156 is provided above the temperature sensor 154 to fix the temperature sensor 154 to the heater 151 side. . In addition, the temperature sensor 154 may have a substantially cylindrical shape, and may be in close contact with the upper side of the heater 151 by the sensor fixing part 156.

In addition, an outer side of the heater 151 is provided with an absorbing member 153 to allow the heat of the heater 151 to be easily transferred to the water. Since the absorbing member 153 receives heat in a state in which water in the heating unit 150 is absorbed, the heat transfer area is increased, thereby improving steam generation efficiency.

In addition, by the absorbing member 153, there is also an effect that can prevent the heat of the heater 151 from being transmitted directly to the lower case 101 or the upper case 102.

In addition, the lower case 101 is provided with a heater seat 158 on which the heater 151 is seated. Here, the steam outlet 155 may be located closer to the reservoir 120 than the heater seat 158. That is, the reservoir 120, the steam outlet 155 and the heater seating portion 158 may be arranged in the order.

On the other hand, between the lower case 101 and the upper case 102, a sealing member 160 for preventing water leakage is interposed. The sealing member 160 is formed to substantially correspond to the shape of the lower case 101. At least a portion of the sealing member 160 is formed to surround the outer circumferential surface of the heater 151.

In the lower case 101, an insertion groove 106 into which the sealing member 160 is inserted is formed. The insertion groove 106 is formed along the edge of the lower case 101.

As shown in FIG. 7, the sealing member 160 is disposed to surround the water reservoir 120 and the heating unit 150 as one member. Therefore, since the sealing may be made over all the portions in which the lower case 101 and the upper case 102 are coupled to each other, there is an effect that the phenomenon of overflowing water in the steam generator 100 may be prevented.

Air introduced through the air suction unit 197 may be moved to the cleaner body (not shown) through the connection unit 30.

The steam discharge part 191 is formed to protrude downwardly from the bottom part 190, and a plurality of steam discharge holes 192 through which steam is discharged are formed on the bottom surface of the steam discharge part 191.

In addition, the lower plate 170, the pressing plate 171 that the user can press to facilitate the separation of the lower plate 170 from the nozzle body 10 and the steam discharge unit 191 A discharge counterpart 171 which is vertically opened to be inserted is included. The discharge counterpart 171 may have a shape and size corresponding to the steam discharge unit 191.

In a state where the lower plate 170 is coupled to the bottom surface 190, the bottom surface of the steam outlet 191 forms a plane substantially the same as the bottom surface of the bottom plate 170. A mop plate is attached to the lower side of the lower plate 170, and the steam discharged from the steam discharge hole 192 may be absorbed by the mop plate.

The lower plate 170 has a corresponding cutout 173 provided at a position corresponding to the supply hole 193. The outside air may be moved to the supply hole 193 through the corresponding cutout 173, and then moved to the inside of the nozzle body 10.

Hereinafter, the operation of the steam generating device 100 according to the embodiment of the present invention will be briefly described.

When the user fills the water tank 110 with water and seats the seating portion 21, the pressure protrusion 125 opens the valve member 142 of the tank cap 140, and the water tank 110. ) May be introduced into the reservoir (120).

Water in the reservoir 120 is moved to the heating unit 150 along the flow path guide 130, and changes from the heating unit 150 to steam to the steam discharge unit 155 and the steam discharge hole 192 Can be discharged to outside. At this time, the water is effectively guided by the flow path guide 130 can be moved to the heating unit 150 by only a small amount.

On the other hand, outside air introduced into the nozzle body 10 through the supply hole 193 may be introduced into the reservoir 120 through the outside air communication unit 200. Accordingly, the reservoir 120 may be maintained at atmospheric pressure, and the water of the water tank 110 may be easily introduced into the reservoir 120.

On the other hand, when the nozzle body 10 is upside down, since the float 240 of the external air communication unit 200 shields the tube connecting portion 220, the water of the reservoir 120 is nozzle body 10 Outflow to the outside can be prevented.

According to the above configuration, while the outside air can be easily communicated to the inside of the steam generating device, there is an effect that the outflow of water from the steam generating device can be prevented.

According to the above embodiment, the external air communication unit is provided in the steam generating device, so that the outside air communicates with the reservoir while water does not pass, so that the pressure inside the reservoir is maintained at atmospheric pressure and the water in the reservoir is not leaked to the outside. As such, industrial applicability is remarkable.
