FIGS. 8 and 9 are views illustrating a coupled state of a tub 100, an additive supply part 600, and a drying part 400 in a cup washer 1000 according to an embodiment of the present disclosure.

A cup washer 1000 according to an embodiment of the present disclosure includes a tub 100, a drying part 400, and an additive supply part 600.

The tub 100 is a portion that provides a space for washing a cup C stored therein. When a cup C is put into the washing space of the tub 100, water is sprayed onto the cup C to wash the cup C.

The drying part 400 is partially connected to the rear surface of the tub 100 and is disposed so that at least a portion of the drying part 400 is spaced apart the rear of the tub 100 by a first space S1 in a state in which a second portion of the drying part 400 is connected to the rear surface of the tub 100 to heat the incoming outside air and supply the heated air to the tub 100.

Specifically, the drying part 400 may be configured to dry the water remaining in the cleaned cup C as described above. That is, the drying part 400 may supply heated air to the tub 100 to dry the cleaned cup C. This drying part 400 may be equipped with a heater for heating air and a blower for forcibly blowing air.

Meanwhile, vibration may be generated in the tub 100 during the process of spraying water into the cup C, and when such vibration is transmitted to the drying part 400, the components of the drying part 400, such as the heater and the blower, may not exhibit their intended functions properly.

Accordingly, it may be desirable to arrange the drying part 400 to be spaced apart from the rear of the tub 100 by the first space S1 to minimize transmission of vibration of the tub 100 to the drying part 400. However, in order to supply air heated in the drying part 400 to the tub 100, a portion of the drying part 400 needs to be connected to the rear surface of the tub 100.

The additive supply part 600 is disposed in the first space S1 and is coupled to the rear surface of the tub 100 to supply an additive to the tub 100.

Specifically, the additive supply part 600 may be configured to supply an additive such as detergent or rinse to the tub 100. That is, the additive supply part 600 may improve washing efficiency by supplying an additive to the tub 100 during the washing process of the cup C.

To this end, it may be desirable for the additive supply part 600 to be disposed close to the tub 100 to smoothly supply the additive to the tub 100. In addition, in order to properly arrange each component within the limited specifications of the cup washer 1000, it is necessary to consider both performance and space efficiency when arranging the tub 100, the drying part 400, and the additive supply part 600.

Therefore, it may be desirable to dispose the additive supply part 600 in the first space S1 between the tub 100 and the drying part 400 and to couple the additive supply part 600 to the rear surface of the tub 100.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the drying part 400 to be spaced apart from the rear of the tub 100 by the first space S1 and placing the additive supply part 600 in the first space S1, transmission of vibration of the tub 100 to the drying part 400 can be minimized to prevent performance degradation, and additive supply to the tub 100 can be smoothly performed.

The cup washer 1000 according to an embodiment of the present disclosure may further include a front panel 21 and a rear panel 22.

The front panel 21 is a portion that covers the front side of the tub 100, and the rear panel 22 is a portion that covers the rear side of the drying part 400. The front panel 21 and the rear panel 22 may define the exterior of the cup washer 1000. That is, the main components of the cup washer 1000 (the tub 100, the drying part 400, the additive supply part 600, and the like) may be arranged in the inside covered by the front panel 21 and rear panel 22 not to be exposed to the outside.

In this case, the rear panel 22 may be connected to an outside air inlet 401 of the drying part 400. That is, a vent 22a is provided in a portion of the rear panel 22 so that air outside the cup washer 1000 can flow into the inside of the cup washer 1000. The vent 22a may be provided in the rear panel 22 in view of the fact that it is desirable to minimize external exposure.

In addition, the air that flows into the inside of the cup washer 1000 through the vent 22a of the rear panel 22 may be introduced into the outside air inlet 401 of the drying part 400, heated, and then supplied to the tub 100.

Therefore, since the outside air inlet 401 of the drying part 400 should be placed close to the rear panel 22, it may be desirable to place the drying part 400 on the rear side of the cup washer 1000.

In addition, as described above, in view of the fact that the drying part 400 including the heater and blower requires frequent inspection and replacement, it is desirable to place the drying part 400 on the rear side of the cup washer 1000 so that the drying part 400 can be checked by removing only the rear panel 22.

In addition, in terms of the overall structure of the cup washer 1000, the tub 100 is configured to allow a user to insert and remove the cup C. Therefore, it is desirable to place the tub 100 on the front side the cup washer 1000 to facilitate user access.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the tub 100 on the front side, placing the drying part 400 on the rear side, and the outside air inlet 401 of the drying part 400 is connected to the rear panel 22, outside air can be smoothly introduced into the drying part 400, and maintenance of the drying part 400 can be easily performed while facilitating user access to the tub 100.

FIGS. 10 and 11 are views illustrating the drying part 400 in the cup washer 1000 according to an embodiment of the present disclosure. FIG. 12 is a view illustrating the arrangement relationship between the tub 100 and the drying part 400 in the cup washer 1000 according to an embodiment of the present disclosure. FIG. 13 is a view illustrating the coupled state of the drying duct 420 and the tub connection pipe 430 in the cup washer 1000 according to an embodiment of the present disclosure. FIG. 14 is a view illustrating the coupled state of the rear frame 12 and the drying part 400 in the cup washer 1000 according to an embodiment of the present disclosure.

In the cup washer 1000 according to an embodiment of the present disclosure, the drying part 400 may include a blowing fan 410 and a drying duct 420.

The blowing fan 410 is configured to draw in outside air through the outside air inlet 401 and to blow the air toward the tub 100. The blowing fan 410 forcibly blows the air so that the air can be forced to flow in the dryer 400 and the tub 100.

One end of the drying duct 420 is coupled to the blowing fan 410, and an internal flow path F10 is defined along a surface parallel to the rear panel 22. That is, an internal flow path F10, which is an air movement path, is defined in the drying duct 420 so that the air forcibly sent by the blowing fan 410 can be moved to the tub 100 along the internal flow path F10.

Meanwhile, in order to supply heated air from the drying part 400 to the tub 100, it is necessary to heat the air in a portion of the internal flow path F10. Thus, the internal flow path F10 needs to have a predetermined length. In this case, when the internal flow path F10 occupies the space in the front-rear direction of the cup washer 1000, the space efficiency may deteriorate due to the structure in which the tub 100, the drying part 400, and the additive supply part 600 are arranged in the front-rear direction of the cup washer 1000.

Therefore, it may be desirable to provide the internal flow path F10 along the surface parallel to the rear panel 22 to minimize the space occupied by the internal flow path F10 in the front-rear direction of the cup washer 1000.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by forming the internal passage F10 along the surface parallel to the rear panel 22 in the drying duct 420 of the drying part 400, the internal flow path F10 can be arranged efficiently in the limited internal space of the cup washer 1000.

In the cup washer 1000 according to an embodiment of the present disclosure, the drying part 400 may further include a tub connection pipe 430 extending from the other end of the drying duct 420 and connected to the rear surface of the tub 100 through a tub connector 431 provided at the end.

As described above, in view of the fact that the additive supply part 600 is disposed in the first space S1 between the drying part 400 and the tub 100 when the internal passage F10 is defined in the drying duct 420 along the surface parallel to the rear panel 22, the drying duct 420 may be arranged to be spaced apart from the tub 100.

Therefore, in order to supply heated air from the drying part 400 to the tub 100, a component may be required to connect the internal flow path F10 of the drying duct 420 to the tub 100.

For this purpose, the tub connection pipe 430 may connect the other end of the drying duct 420 to the rear surface of the tub 100. In this case, the portion of the tub connection pipe 430 connected to the rear surface of the tub 100 may be the tub connector 431.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by connecting the tub 100 to the drying duct 420 by the tub connection pipe 430 of the drying part 400, dry air can be smoothly supplied to the tub 100 while the tub 100 and the drying duct 420 are spaced apart from each other.

In the cup washer 1000 according to an embodiment of the present disclosure, the blowing fan 410 may be placed at a relatively higher position than the tub connector 431. That is, the blowing fan 410 may be placed relatively higher than the position where the tub connection pipe 430 is connected to the tub 100.

In view of the fact that washing water is accommodated in the tub 100 when washing the cup C, the washing water may also flow into the tub connection pipe 430 connected to the tub 100 through the tub connector 431. In this case, when the blower fan 410 is placed at a lower position than the tub connector 431, there may be a relatively high possibility that the washing water flowing into the tub connection pipe 430 through the tub connector 431 will affect the blowing fan 410.

Therefore, it may be desirable to minimize the effect of the washing water on the flowing fan 410 even when the washing water in the fub 100 flows into the tub connection pipe 430 by placing the blowing fan 410 at a relatively higher position than the tub connector 431.

Meanwhile, in order to ensure that more air volume is supplied to the tub 100 when air is forcibly sent through the blower fan 410, it may be advantageous for the internal flow path F10 between the tub 100 and the blower fan 410 to be shorter. In addition, it may be advantageous to place the blowing fan 410 at a high portion to forcibly blow air toward the tub 100 to a certain downward portion.

Therefore, it may be desirable to cause the air forcibly sent by the blowing fan 410 to move to a certain downward portion by placing the blowing fan 410 at a relatively higher position than the tub connector 431.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the tub connection pipe 430 at a relatively higher position than the position where the tub connection pipe 430 is connected to the tub 100, the movement path of the air blown from the blowing fan 410 to the tub 100 can be efficiently formed while the washing water contained in the tub 100 does not affect the blowing fan 410 during the washing process.

In the cup washer 1000 according to an embodiment of the present disclosure, the drying part 400 may further include an air heater 440. In this case, the internal flow path F10 may include a first section F10a, a second section F10b, and a third section F10c.

Specifically, the air heater 440 is disposed in the drying duct 420 to heat the air passing through the internal flow path F10, and may heat air through heat exchange with relatively low temperature air that comes into contact with the air heater.

The first section F10a is a portion of the internal flow path F10 that extends upward from the blowing fan 410, and the air flowing into the drying part 400 through the outside air inlet 401 may be moved upward along the first section F10a within the drying duct 420 via the blowing fan 410.

The second section F10b is a portion which extends laterally from the first section F10a and in which the air heater 440 is disposed. That is, the air moved upward along the first section F10a within the drying duct 420 may be moved laterally along the second section F10b. Then, the air passing through the second section F10b may be heated by the air heater 440 disposed in the second section F10b.

The third section F10c is a portion extending downward from the second section F10b to the tub connection pipe 430. The air moved laterally along the second section F10b inside the drying duct 420 can be moved downward along the third section F10c and supplied to the tub 100 through the tub connection pipe 430.

As described above, the internal flow path F10 may generally have a ∩ shape or an upside-down “u” shape, and the air heater 440 may be disposed in the upper portion of the internal flow path F10. Accordingly, even if the washing water in the tub 100 flows into the tub connection pipe 430, the impact of the washing water on the air heater 440 can be minimized.

Meanwhile, in order to ensure that the heated air is supplied into the tub 100 with the least amount of heat loss, it may be desirable to place the air heater 440 relatively close to the tub 100.

For this purpose, it may be desirable to place the air heater 440 in the third section F10c of the drying duct 420, but when the air heater 440 is placed excessively close to the tub connector 431, there may be a high risk that the air heater 440 will be affected by washing water flowing into the tub connection pipe 430.

Accordingly, in order to minimize heat loss of heated air and to minimize the influence of washing water, the air heater 440 may be placed at the upper end portion of the third section F10c of the drying duct 420.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the air heater 440 of the drying part 400 in the upper end portion of the internal flow path F10, the washing water contained in the tub 100 can be prevented from affecting the air heater 440 during the washing process.

In the cup washer 1000 according to an embodiment of the present disclosure, the tub connection pipe 430 may have a shape of which the height relative to the base decreases toward the tub connector 431. That is, the tub connection pipe 430 may be configured to have a structure inclined downward toward the tub 100.

As described above, when washing the cup C, the washing water in the tub 100 may flow into the tub connection pipe 430. Accordingly, it may be desirable to form the tub connection pipe 430 in a structure inclined downward toward the tub 100 such that the washing water flowing into the tub connection pipe 430 is returned to the tub 100.

In addition, when the blower fan 410 is placed at a relatively higher position than the tub connector 431 as described above, so that the air pressured by the blower fan 410 moves to a certain downward portion, it may be desirable to form the tub connection pipe 430 to have a structure inclined downward toward the tub 100 in terms of air direction.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by forming the tub connection pipe 430 in a structure inclined downward toward the tub 100, the washing water can be returned to the tub 100 and the air blown from the blowing fan 410 placed relatively high can be blown more smoothly toward the tub 100, even when the washing water contained in the tub 100 flows into the tub connection pipe 430 during the washing process.

In the cup washer 1000 according to an embodiment of the present disclosure, the drying duct 420 may include a first assembly 421 and a second assembly 422. In this case, the tub connection pipe 430 may be inserted and coupled to the coupled ends of the first assembly 421 and the second assembly 422.

Specifically, the first assembly 421 is a portion that covers the front side of the internal flow path F10, and the second assembly 422 is a portion that is coupled to the first assembly 421 to cover the rear side of the internal flow path F10.

That is, the internal space provided by coupling the first assembly 421 and the second assembly 422 may define the internal flow path F10 of the drying duct 420. Then, the drying duct 420 and the tub connection pipe 430 may be coupled by inserting the tub connection pipe 430 into the coupled ends of the first assembly 421 and the second assembly 422.

In view of the fact that the air heater 440 is disposed in the internal flow path F10 (particularly, the second section F10b) of the drying duct 420, assembly of the drying duct 420 and the air heater 440 may be difficult. Therefore, it may be desirable to separately manufacture the drying duct 420 as the first assembly 421 and the second assembly 422 and then to assemble the first assembly 421 and the second assembly 422 in the state in which the air heater 440 is disposed.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by forming the drying conduct 420 by coupling the first assembly 421 and the second assembly 422, the drying part 400 can be easily assembled.

In the cup washer 1000 according to an embodiment of the present disclosure, the tub connection pipe 430 may be formed in an integrated tubular shape and extend from the other end of the drying duct 420. That is, unlike the separately manufactured drying duct 420, the tub connection pipe 430 may be made of an integrated tubular member.

As described above, in view of the fact that the washing water in the tub 100 may flow into the tub connection pipe 430 when washing the cup C, it may be desirable to make the tub connection pipe 430 as an integral member to minimize water leakage.

In particular, in view of the fact that the tub connection pipe 430 is the part that most directly receives the vibration of the tub 100, it needs to be formed integrally to have a predetermined rigidity so that its original function can be properly performed.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by forming the tub connection pipe 430 in an integrated tubular shape, leakage can be minimized when the washing water contained in the tub 100 flows into the tub connection pipe 430 during the washing process.

In the cup washer 1000 according to an embodiment of the present disclosure, the tub connection pipe 430 may be fitted and coupled to the other end of the drying duct 420. That is, the coupled portion between the tub connection pipe 430 and the drying duct 420 may be simply fitted without forming a separate airtight structure.

As described above, when washing the cup C, the washing water in the tub 100 may flow into the tub connection pipe 430, but in an unintended abnormal situation, the washing water may flow into the drying duct 420 beyond the tub connection pipe 430.

In this case, in view of the fact that the washing water may damage the air heater 440 or the blowing fan 410 and may reduce the performance of the air heater or the blowing fan, it may be less disadvantageous for the washing water to be discharged to the outside of the tub connection pipe 430 and the drying duct 420 rather than flowing into the drying duct 420.

Therefore, it may be desirable to fit the drying duct 420 and the tub connection pipe 430 to each other by fitting such that washing water is discharged through the coupled portion of the tub connection pipe 430 and the drying duct 420 before the washing water flows beyond the tub connection pipe 430 into the drying duct 420.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by coupling the drying duct 420 and the tub connection pipe 430 in a fitting manner, it is possible to minimize washing water flowing into the drying duct 420 by being discharged through the connection portion of the drying duct 420 and the tub connection pipe 430, which is not completely sealed, even when the washing water flows into a position higher than the hub connection pipe 430 in an unintended situation.

In the cup washer 1000 according to an embodiment of the present disclosure, the other end of the drying duct 420 may be placed at a position relatively higher than the maximum water level of the tub 100. That is, the location where the drying duct 420 and the tub connection pipe 430 are coupled may be placed to be higher than the maximum water level of the tub 100.

As described above, since the tub 100 and the tub connection pipe 430 are connected through the tub connector 431, washing water may flow into the tub connection pipe 430 as high as the water level in the tub 100.

In this case, since it is necessary to prevent washing water from flowing into the drying duct 420 beyond the tub connection pipe 430, it may be desirable to place the location where the drying duct 420 and the tub connection pipe 430 are connected to be higher than the maximum water level in the tub 100.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the location where the drying duct 420 and the tub connection pipe 430 are coupled to be relatively higher than the maximum water level in the tub 100, it is possible to minimize the washing water flowing into the drying duct 420 at the maximum water level in the tub 100.

In the cup washer 1000 according to an embodiment of the present disclosure, the other end of the drying duct 420 may be placed at a relatively lower position than the outside air inlet 401. That is, the location where the drying duct 420 and the tub connection pipe 430 are coupled may be placed to be lower than the outside air inlet 401.

As described above, since the washing water may be discharged through the connection portion of the drying duct 420 and the tub connection pipe 430 in an unintentional abnormal situation, the washing water discharged in this way may flow into the outside air inlet 401.

In this case, since problems such as damage to the blowing fan 410 or deterioration of performance may occur due to the washing water, it is necessary to prevent washing water discharged through the connection portion of the drying duct 420 and the tub connection pipe 430 from flowing into the outside air inlet 401.

Therefore, it may be desirable to place the location where the drying duct 420 and the tub connection pipe 430 are coupled to be lower than the outside air inlet 401 to minimize washing water flowing into the outside air inlet 401 even when the washing water is discharged to the corresponding portion.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the location where the drying duct 420 and the tub connection pipe 430 are coupled to be relatively lower than the outside air inlet 401, it is possible to minimize washing water flowing into the outside air inlet 401 when the washing water is discharged through the connection portion of the drying duct 420 and the tub connection pipe 430 in an unintended situation.

The cup washer 1000 according to an embodiment of the present disclosure may further include a front frame 11 and a rear frame 12.

The front frame 11 is disposed on the front side of the tub 100 and supports the front panel 21, and the rear frame 12 is disposed on the rear side of the drying part 400 and supports the rear panel 22.

That is, the front frame 11 and the rear frame 12 form the framework of the cup washer 1000 so that the main components of the cup washer 1000 can be supported by the front frame 11 and the rear frame 12.

In this case, the front frames 11 may be arranged as a pair on the front side of the tub 100, and the rear frames 12 may be arranged as a pair on the rear side of the drying part 400. In addition, the front frame 11 and the rear frame 12 may be coupled to a separate frame structure to distribute and transmit a load applied thereto.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by causing the front frame 11 to support the front panel 21 and the rear frame 12 to support the rear panel 22, the cup washer 1000 can be maintained in a stable state with a certain rigidity.

In the cup washer 1000 according to an embodiment of the present disclosure, the drying part 400 may be supported by being coupled to the rear frame 12. That is, the drying part 400 may be supported on the rear frame 12 rather than on the tub 100.

As described above, since vibration is generated in the tub 100 during the washing process, it is necessary to minimize the transmission of such vibration to the drying part 400. In this case, when the drying part 400 is supported on the tub 100, it may be undesirable in that the vibration of the tub 100 is transmitted to the drying part 400 to a relatively large extent.

Therefore, it may be desirable to minimize the effect of vibration of the tub 100 on the drying part 400 by allowing the drying part 400 disposed on the rear side of the tub 100 to be supported by the rear frame 12 which supports the rear panel 22.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by coupling the drying part 400 to be supported by the rear frame 12, the drying part 400 can be maintained in a stable state even if vibration of the tub 100 is transmitted thereto.

In the cup washer 1000 according to an embodiment of the present disclosure, the second assembly 422 may be coupled by being fastened to the rear frame 12. That is, the drying part 400 may be coupled to the rear frame 12 by fastening the second assembly 422 disposed on the rear side of the drying duct 420 to the rear frame 12.

As described above, in view of the fact that the drying part 400 requires frequent inspection and replacement, since the drying part 400 is placed on the rear side of the cup washer 1000, the drying part 400 can be checked by only removing the rear panel 22.

In this case, by fastening the second assembly 422 of the drying duct 420 to the rear frame 12, the drying duct 420 and the rear frame 12 can be easily assembled and disassembled when necessary, and the drying duct 420 including the first assembly 421 and the second assembly 422 can also be easily assembled and disassembled.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by fastening the second assembly 422 to the rear frame 12, the drying part 400 and the rear frame 12 can be easily assembled and disassembled.

FIGS. 15 and 16 are views illustrating an air discharge part 700 in the cup washer 1000 according to an embodiment of the present disclosure. FIG. 17 is a cross-sectional view of the air discharge part 700 illustrated in FIG. 16.

The cup washer 1000 according to an embodiment of the present disclosure may further include an air discharge part 700 installed at the upper end of the tub 100 so that the air inside the tub is discharged.

As described above, when a cup C is dried by supplying heated air from the drying part 400 to the tub 100, it is necessary to discharge air that has been used for drying and is at a relatively low temperature to the outside of the tub 100.

In this case, since it is not desirable to discharge the washing water remaining inside the tub 100 together with the discharged air, it may be desirable to provide a structure in which only the air is discharged while preventing the washing water from being discharged.

Therefore, by installing the air discharge part 700 at the upper end of the tub 100 to discharge air at a location above the maximum water level in the tub 100, only air can be discharged without washing water being discharged.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by causing the air inside the tub 100 to be discharged through the air discharge part 700 installed at the upper end of the tub 100, the air can be discharged without being affected by the washing water inside the tub 100.

In the cup washer 1000 according to an embodiment of the present disclosure, the air discharge part 700 may be connected between the rear surface of the tub 100 and the rear panel 22. That is, an air outlet 22b is provided in a portion of the rear panel 22 so that the air inside the tub 100 can be discharged to the outside of the cup washer 1000.

Like the above-described vent 22a, it is desirable to minimize external exposure of the air outlet 22b, and in view of the fact that the air discharged from the cup washer 1000 may cause discomfort or the like to the user when the air comes into contact with the user, the air outlet 22b may be provided in the rear panel 22.

Accordingly, since the air discharge part 700 is connected between the rear surface of the tub 100 and the rear panel 22, the air inside the tub 100 can be discharged to the rear side of the cup washer 1000 through the rear panel 22.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by connecting the air discharge part 700 between the rear surface of the tub 100 and the rear panel 22, it is possible to minimize exposure of the discharged air to the user.

In the cup washer 1000 according to an embodiment of the present disclosure, the portion of the air discharge part 700 connected to the tub 100 may be placed at a relatively lower position than the portion connected to the rear panel 22.

As described above, even when the air discharge part 700 is placed at the upper end of the tub 100 so that the washing water is not discharged to the air discharge part 700, in some cases, the washing water may flow into the air discharge part 700 in situations such as splashing.

Accordingly, it may be desirable to provide the portion where the air discharge part 700 is connected to the tub 100 to be relatively lower than the portion where the air discharge part 700 is connected to the rear panel 22 so that the washing water flowing into the air discharge part 700 can be returned again into the tub 100.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by placing the location where the air discharge part 700 is connected to the tub 100 to be relatively lower than the location where the air discharge part 700 is connected to the rear panel 22, the washing water inside the tub 100 can be returned to the tub 100 even when the washing water flows into the air discharge part 700.

In the cup washer 1000 according to an embodiment of the present disclosure, the air discharge part 700 may have a water barrier 710 formed along a direction intersecting the longitudinal direction.

As described above, even when the washing water flowing into the air discharge part 700 is recovered by varying the height of both ends of the air discharge part 700, there is still a risk that a certain amount of the washing water may be discharged to the outside through the air discharge part 700.

Therefore, it may be desirable to form a step such as the water barrier 710 in the longitudinal direction of the air discharge part 700 so that the washing water flowing into the air discharge part 700 is blocked by the water barrier 710 and is prevented from being discharged to the outside.

In this way, in the cup washer 1000 according to an embodiment of the present disclosure, by forming the water barrier 710 is on the air discharge path of the air discharge part 700, it is possible to minimize the discharge of washing water flowing into the air discharge part 700 to the outside.

The cup washer 1000 according to an embodiment of the present disclosure may include a tub 100 and a drying part 400. In this case, the drying part 400 may include a blowing fan 410, a drying duct 420, and a tub connection pipe 430.

Specifically, the tub 100 may provide a space where a cup C accommodated therein is washed.

The drying part 400 may be placed on the rear side of the tub 100 in a state in which a portion thereof is connected to the rear surface of the tub 100 to heat incoming outside air and then to supply the heated air to the tub 100.

The blowing fan 410 can suction outside air through the outside air inlet 401 and blow the air toward the tub 100.

The drying duct 420 may include a first assembly 421, one end of which is coupled to the blowing fan 410 to cover the front side of the internal flow path F10, and a second assembly 422 which is coupled to the first assembly 421 to cover the rear side of the internal flow path F10.

The tub connection pipe 430 may have an integrated tubular shape extending from the other end of the drying duct 420, and may be connected to the rear surface of the tub 100 through the tub connector 431 provided at the end thereof.

Although specific embodiments of the present disclosure have been described and illustrated above, it is evident to a person ordinarily skilled in the art that the present disclosure is not limited to the described embodiments, and various changes and modifications can be made without departing from the technical idea and scope of the present disclosure. Accordingly, such modifications or variations should not be understood individually from the technical spirit and viewpoint of the present disclosure, and the modifications and variations should be deemed to fall within the scope of the claims of the present disclosure.
