[0091] The water mixed with the additive passes through the filter unit 800 by gravity and flows into the sump 60 below the tub 100, and the circulation pump 70 pressurizes the water flowing into the sump 60 and directs it toward the first injection nozzle 310.

[0092] The first spray nozzle 310 sprays the water mixed with the additive toward the inside and outside of the cup C. Also, the circulation pump 70 supplies the water flowing into the sump 60 into the tub 100 through the cleaning water spray unit 95. The cleaning water spray unit 95 sprays the water mixed with the additive toward the cup lid Ca.

[0093] The circulation pump 70 operates for a certain period of time (set time). When the certain period of time has elapsed, the water flowing into the sump 60 moves to the discharge pipe 81 through the drain pump 80 and is discharged outside the cup washer 1000 (the normal cleaning process is completed).

[0094] The additive may include a first additive and a second additive. The first additive may be provided as a detergent. The second additive may be provided as a conditioner. In this case, the normal cleaning process may include a first normal cleaning process and a second normal cleaning process.

[0095] The first normal cleaning process may be a process of cleaning the cup C with water mixed with the first additive. The second normal cleaning process may be a process of cleaning the cup C with water mixed with the second additive. The first normal cleaning process and the second normal cleaning process may be performed sequentially (continuously).

[0096] When the normal cleaning process is completed, the drying process is performed. The drying unit 400 supplies heated air into the tub 100. In this process, the moist air in the tub 100 is discharged to the outside. The drying process is performed for a certain period of time (completion of the drying process).

[0097] The second spray nozzle 320 may be connected to the water supply pipe. The three-way valve may be introduced (installed) between the water supply pipe and the water storage unit 50. The second spray nozzle 320 may be connected to the water supply pipe via the three-way valve. The on-off valve may be introduced (installed) between the second spray nozzle 320 and the three-way valve. The controller 40 may control the three-way valve and the on-off valve.

[0098] The quick cleaning mode can include a quick cleaning process and a drying process. When the user selects the "quick cleaning mode" through the screen of the display unit 30, the second spray nozzle 320 is connected to the water supply pipe through the three-way valve. In the quick cleaning mode, the additive is not supplied into the tub 100.

[0099] The second spray nozzle 320 sprays water without the additive mixed therein into the cup C. The on-off valve opens the flow path between the water supply pipe and the second spray nozzle 320 for a certain period of time. When a certain period of time has elapsed, the water that has flowed into the sump 60 moves to the discharge pipe 81 via the discharge pump 80 and is discharged to the outside of the cup washer 1000 (completion of the quick cleaning process).

[0100] When the quick cleaning process is completed, the drying process is performed. The drying unit 400 supplies heated air into the tub 100. In this process, the moist air in the tub 100 is discharged to the outside. The drying process is performed for a certain period of time (completion of the drying process).

[0101] FIG. 8 and FIG. 9 are diagrams showing the combined state of the tub 100, the additive supply unit 600, and the drying unit 400 in the cup washer 1000 according to an embodiment of the present invention.

[0102] A cup washer 1000 according to an embodiment of the present invention includes a tab 100, a drying unit 400, and an additive supply unit 600.

[0103] The tab 100 is a component that provides (grants) a space for washing the cup C accommodated therein. When the cup C is introduced (put into) the washing space of the tab 100, water is sprayed onto the cup C and the cup C is washed.

[0104] The drying unit 400 is partially connected to and disposed behind the tab 100. In a state where the second part of the drying unit 400 is connected to the rear surface of the tab 100, heats the inflowing outside air, and supplies the heated air to the tab 100, at least a part of the drying unit 400 is positioned so as to be separated from the rear surface of the tab 100 by a first space S1.

[0105] Specifically, the drying unit 400 is configured to dry the moisture remaining on the washed cup C as described above. That is, the drying unit 400 can be configured to supply the heated air to the tab 100 and dry the washed (clean) cup C. The drying unit 400 may include a heater for heating air and a blower for forcibly blowing air.

[0106] On the other hand, in the process of spraying water onto the cup C, vibration may occur in the tab 100. If this vibration is transmitted to the drying unit 400, components of the drying unit 400, such as the heater and the blower, may not be able to perform their original functions.

[0107] Therefore, it is desirable to minimize the transmission of the vibration of the tab 100 to the drying unit 400 by disposing the drying unit 400 at a position separated from the rear surface of the tab 100 by only the first space S1. However, in order to supply the air heated by the drying unit 400 to the tab 100, it is necessary to connect a part of the drying unit 400 to the rear surface of the tab 100.

[0108] The additive supply unit 600 is disposed in the first space S1, coupled to the rear surface of the tab 100, and supplies an additive to the tab 100.

[0109] Specifically, the additive supply unit 600 may be configured to supply additives such as detergents and rinses to the tab 100. That is, the additive supply unit 600 can improve the cleaning efficiency by supplying an additive to the tab 100 during the cleaning process of the cup C.

[0110] For this reason, it is desirable that the additive supply unit 600 be disposed near the tab 100 in order to smoothly supply the additive to the tab 100. Also, in order to appropriately 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 tab 100, the drying unit 400, and the additive supply unit 600.

[0111] It is desirable to dispose the additive supply unit 600 in the first space S1 between the tab 100 and the drying unit 400, and couple the additive supply unit 600 to the rear surface of the tab 100.

[0112] Thus, in the cup washer 1000 according to an embodiment of the present invention, by disposing the drying unit 400 at a position separated from the tab 100 by only the first space S1 from the rear, and disposing the additive supply unit 600 within the first space S1, transmission of the vibration of the tab 100 to the drying unit 400 is minimized, effectively preventing performance degradation, and at the same time, the additive supply to the tab 100 can be performed smoothly.

[0113] The cup washer 1000 according to an embodiment of the present invention may further include a front panel 21 and a rear panel 22.

[0114] The front panel 21 is a part that covers the front side of the tab 100, and the rear panel 22 is a part that covers the rear side of the drying section 400. The front panel 21 and the rear panel 22 define the exterior of the cup washer 1000. That is, the main components of the cup washer 1000 (such as the tab 100, the drying section 400, the additive supply section 600, etc.) can be arranged inside and covered by the front panel 21 and the rear panel 22 so as not to be exposed to the outside.

[0115] In this case, the rear panel 22 may be connected to the outside air inlet 401 of the drying section 400. That is, the vent 22a is provided as a part of the rear panel 22, and the air outside the cup washer 1000 can flow into the inside of the cup washer 1000. The vent 22a may be provided on the rear panel 22 from the viewpoint of minimizing exposure to the outside.

[0116] Also, the air that has flowed into the inside of the cup washer 1000 from the vent 22a of the rear panel 22 is introduced into the outside air inlet 401 of the drying section 400, heated, and then supplied to the tab 100.

[0117] Therefore, since the outside air inlet 401 of the drying section 400 needs to be arranged near the rear panel 22, it is desirable to arrange the drying section 400 at the rear side of the cup washer 1000.

[0118] Also, as described above, the drying section 400 equipped with a heater and a blower is preferably arranged at the rear side of the cup washer 1000 from the viewpoint that frequent inspections and replacements are required, and the drying section 400 can be inspected by simply removing only the rear panel 22.

[0119] Also, in terms of the overall structure of the cup washer 1000, the tab 100 is configured so that the user can insert or remove the cup C. Therefore, it is desirable to arrange the tab 100 at the front side of the cup washer 1000 so that the user can easily access it.

[0120] Thus, in the cup washer 1000 according to an embodiment of the present invention, the tab 100 is disposed on the front side, the drying unit 400 is disposed on the rear side, and by connecting the outside air inlet 401 of the drying unit 400 to the rear panel 22, outside air can be smoothly introduced into the drying unit 400, facilitating user access to the tab 100 while also facilitating the maintenance of the drying unit 400.

[0121] FIGS. 10 and 11 are diagrams showing the drying unit 400 in the cup washer 1000 according to an embodiment of the present invention. FIG. 12 is a diagram showing the arrangement relationship between the tab 100 and the drying unit 400 in the cup washer 1000 according to an embodiment of the present invention. FIG. 13 is a diagram showing the coupling state of the drying duct 420 and the tab connection pipe 430 in the cup washer 1000 according to an embodiment of the present invention. FIG. 14 is a diagram showing the coupling state of the rear frame 12 and the drying unit 400 in the cup washer 1000 according to an embodiment of the present invention.

[0122] In the cup washer 1000 according to an embodiment of the present invention, the drying unit 400 may include a blower fan 410 and a drying duct 420.

[0123] The blower fan 410 is configured to suck outside air from the outside air inlet 401 and blow the outside air toward the tab 100. The blower fan 410 forcibly blows air, and the air can be forcibly introduced into the dryer 400 and the tab 100.

[0124] One end of the drying duct 420 is coupled to the blower fan 410, and the internal flow path F10 is defined along a plane parallel to the rear panel 22. That is, the internal flow path F10, which is the air movement path, is defined in the drying duct 420, and the air forcibly blown by the blower fan 410 can move along the internal flow path F10 to the tab 100.

[0125] On the one hand, in order to supply the air heated in the drying section 400 to the tab 100, it is necessary to heat the air in a part of the internal flow path F10. Therefore, the internal flow path F10 needs to have a predetermined length. In this case, if the internal flow path F10 occupies space in the front-rear direction of the cup washer 1000, the space efficiency may decrease due to the structure in which the tab 100, the drying section 400, and the additive supply section 600 are arranged in the front-rear direction of the cup washer 1000.

[0126] Therefore, it is desirable to provide the internal flow path F10 along a plane parallel to the rear panel 22 and minimize the space occupied by the internal flow path F10 in the front-rear direction of the cup washer 1000.

[0127] Thus, in the cup washer 1000 according to an embodiment of the present invention, in the drying duct 420 of the drying section 400, by forming the internal flow path F10 along a plane parallel to the rear panel 22, the internal flow path F10 can be efficiently arranged within the limited internal space of the cup washer 1000.

[0128] In the cup washer 1000 according to an embodiment of the present invention, the drying section 400 may further include a tab connection pipe 430 that extends from the other end of the drying duct 420 and is connected to the rear surface of the tab 100 via a tab connector 431 provided at the end.

[0129] As described above, in view of the fact that when the internal passage F10 is defined (specified) in the drying duct 420 along a plane parallel to the rear panel 22, the additive supply section 600 is arranged in the first space S1 between the drying section 400 and the tab 100, the drying duct 420 may be arranged at a position separated from the tab 100.

[0130] Therefore, in order to supply the air heated from the drying section 400 to the tab 100, components for connecting the internal flow path F10 of the drying duct 420 to the tab 100 are required.

[0131] Therefore, the tab connection pipe 430 can connect the other end of the drying duct 420 to the rear surface of the tab 100. In this case, the portion of the tab connection pipe 430 connected to the rear surface of the tab 100 becomes the tab connector 431.

[0132] Thus, in the cup washer 1000 according to an embodiment of the present invention, by connecting the tab 100 to the drying duct 420 through the tab connection pipe 430 of the drying unit 400, the tab 100 and the drying duct 420 are located at positions separated from each other, so that dry air can be smoothly supplied to the tab 100.

[0133] In the cup washer 1000 according to an embodiment of the present invention, the blower fan 410 is disposed at a position relatively higher than the tab connector 431. That is, the blower fan 410 is disposed at a position relatively higher than the position where the tab connection pipe 430 is connected to the tab 100.

[0134] In view of the fact that the washing water is contained in the tab 100 when washing the cup C, the washing water can also flow into the tab connection pipe 430 connected to the tab 100 through the tab connector 431. In this case, if the blower fan 410 is disposed at a position lower than the tab connector 431, there is a relatively high possibility that the washing water flowing into the tab connection pipe 430 through the tab connector 431 will affect the blower fan 410.

[0135] Therefore, for example, by disposing the blower fan 410 at a position relatively higher than the tab connector 431, even when the washing water in the tab 100 flows into the tab connection pipe 430, it is desirable to minimize the influence of the washing water on the blower fan 410.

[0136] On the other hand, when forcibly sending air through the blower fan 410, in order to supply a larger air volume to the tab 100, it is advantageous to shorten the internal flow path F10 between the tab 100 and the blower fan 410. Also, it is advantageous to dispose the blower fan 410 at a high position and forcibly send air downward at a certain angle toward the tab 100.

[0137] Therefore, by arranging the blower fan 410 at a position relatively higher than the tab connector 431, it is desirable to move the air forcibly sent out by the blower fan 410 to a certain lower part.

[0138] Thus, in the cup washer 1000 according to one embodiment of the present invention, by arranging the tab connection pipe 430 at a position relatively higher than the position where it is connected to the tab 100, the cleaning water contained in the tab 100 during the cleaning process does not affect the blower fan 410, and an efficient movement path of the air blown from the blower fan 410 to the tab 100 can be formed.

[0139] In the cup washer 1000 according to one embodiment of the present invention, the drying unit 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.

[0140] Specifically, the air heater 440 is provided in the drying duct 420, heats the air passing through the internal flow path F10, and can heat the air by heat exchange with the relatively low-temperature air in contact with the air heater.

[0141] The first section F10a is a part of the internal flow path F10 extending upward from the blower fan 410, and the air flowing into the drying unit 400 from the outside air inlet 401 moves upward along the first section F10a in the drying duct 420 via the blower fan 410.

[0142] The second section F10b is a portion extending horizontally from the first section F10a, and the air heater 440 is arranged therein. That is, the air that has moved upward along the first section F10a in the drying duct 420 can move horizontally along the second section F10b. And the air passing through the second section F10b is heated by the air heater 440 arranged in the second section F10b.

[0143] The third section F10c is a portion that extends downward from the second section F10b to the tab connection pipe 430. The air that has moved horizontally along the second section F10b within the drying duct 420 moves downward along the third section F10c and is supplied to the tab 100 via the tab connection pipe 430.

[0144] As described above, the internal flow path F10 generally has an n - shape or an inverted "U" shape, and the air heater 440 may be disposed at the upper part of the internal flow path F10. Thereby, even if the washing water in the tab 100 flows into the tab connection pipe 430, the influence of the washing water on the air heater 440 can be minimized.

[0145] On the other hand, in order to supply the heated air into the tab 100 with minimal heat loss, it is desirable to dispose the air heater 440 relatively close to the tab 100.

[0146] For this reason, it is desirable to dispose the air heater 440 in the third section F10c of the drying duct 420. However, if the air heater 440 is disposed too close to the tab connector 431, the risk that the air heater 440 is affected by the washing water flowing into the tab connection pipe 430 becomes high.

[0147] Therefore, in order to minimize the heat loss of the heated air and to minimize the influence of the washing water, the air heater 440 may be disposed at the upper end of the third section F10c of the drying duct 420.

[0148] Thus, in the cup washer 1000 according to an embodiment of the present invention, by disposing the air heater 440 of the drying unit 400 at the upper end of the internal flow path F10, it is possible to prevent the washing water contained in the tab 100 from affecting the air heater 440 during the washing process.

[0149] In the cup washer 1000 according to an embodiment of the present invention, the tab connection pipe 430 can be configured to have a shape in which the height with respect to the base decreases toward the tab connector 431. That is, the tab connection pipe 430 can be configured to have a structure that slopes downward toward the tab 100.

[0150] As described above, when washing the cup C, the washing water in the tab 100 may flow into the tab connection pipe 430. Therefore, it is desirable to form the tab connection pipe 430 in a structure that slopes downward toward the tab 100 so that the washing water flowing into the tab connection pipe 430 returns to the tab 100.

[0151] Also, as described above, when the blower fan 410 is disposed at a position relatively higher than the tab connection pipe 431, the air pressurized by the blower fan 410 moves to a certain lower portion, and it is desirable to form the tab connection pipe 430 so as to have a structure that slopes downward toward the tab 100 when viewed from the direction of the air.

[0152] Thus, in the cup washer 1000 according to an embodiment of the present invention, by forming the tab connection pipe 430 in a structure that slopes downward toward the tab 100, for example, during the washing process, even if the washing water contained in the tab 100 flows into the tab connection pipe 430, the washing water can still return to the tab 100, and the air blown (ventilated) from the blower fan 410 disposed at a relatively high position can be blown toward the tab 100 more smoothly.

[0153] In the cup washer 1000 according to an embodiment of the present invention, the drying duct 420 can include a first assembly 421 and a second assembly 422. In this case, the tab connection pipe 430 can be inserted and coupled to the coupling end of the first assembly 421 and the second assembly 422.

[0154] 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 and covers the rear side of the internal flow path F10.

[0155] That is, the internal space provided by coupling the first assembly 421 and the second assembly 422 can define the internal flow path F10 of the drying duct 420. And the drying duct 420 and the tab connection pipe 430 can be coupled by inserting the tab connection pipe 430 into the coupling end of the first assembly 421 and the second assembly 422.

[0156] Considering that the air heater 440 is disposed in the internal flow path F10 (particularly, the second section F10b) of the drying duct 420, the assembly of the drying duct 420 and the air heater 440 may be difficult. Therefore, it is desirable to separately manufacture the drying duct 420 into the first assembly 421 and the second assembly 422, and then assemble the first assembly 421 and the second assembly 422 with the air heater 440 disposed.

[0157] Thus, in the cup washer 1000 according to an embodiment of the present invention, by coupling the first assembly 421 and the second assembly 422 to form the drying passage 420, the drying unit 400 can be easily assembled.

[0158] In the cup washer 1000 according to an embodiment of the present invention, the tab connection pipe 430 is formed in an integrated tubular form (tubular body) and extends from the other end of the drying duct 420. That is, unlike the drying duct 420 manufactured separately, the tab connection pipe 430 may be composed of an integrated pipe member.

[0159] As described above, considering that the washing water in the tab 100 may flow into the tab connection pipe 430 when washing the cup C, it is desirable to configure the tab connection pipe 430 as an integrated member to minimize water leakage (water leakage).

[0160] In particular, since the tab connection pipe 430 is the part that most directly receives the vibration of the tab 100, it is necessary to integrally mold it to have a predetermined rigidity so that its original function can be properly exerted.

[0161] Thus, in the cup washer 1000 according to an embodiment of the present invention, by forming the tab connection pipe 430 into an integrated tube form (tubular body), when the cleaning water contained in the tab 100 flows into the tab connection pipe 430 during the cleaning process, leakage can be minimized.

[0162] In the cup washer 1000 according to an embodiment of the present invention, the tab connection pipe 430 can be fixed (inserted, fixed, connected) to the other end of the drying duct 420 and joined. That is, the joint portion between the tab connection pipe 430 and the drying duct 420 can be simply fixed (inserted, fixed, connected) without forming a separate airtight structure.

[0163] As described above, when cleaning the cup C, the cleaning water in the tab 100 may flow into the tab connection pipe 430. However, if an unintended abnormal situation occurs, the cleaning water may flow into the drying duct 420 beyond the tab connection pipe 430.

[0164] Considering that in this case, the cleaning water may damage the air heater 440 or the blower fan 410 and may reduce the performance of the air heater or the blower fan, it is considered that it is less disadvantageous for the cleaning water to be discharged outside the tab connection pipe 430 and the drying duct 420 rather than flowing into the drying duct 420.

[0165] Therefore, it is desirable to fix (insert, fix, connect) the drying duct 420 and the tab connection pipe 430 before the cleaning water flows into the drying duct 420 beyond the tab connection pipe 430 so that the cleaning water is discharged from the joint portion between the tab connection pipe 430 and the drying duct 420.

[0166] Thus, in the cup washer 1000 according to one embodiment of the present invention, by coupling the drying duct 420 and the tab connection pipe 430 by a fixing (inserting, fixing, connecting) method, even if an unintended situation occurs, for example, when washing water flows into a position higher than the tab connection pipe 430, the washing water flowing into the drying duct 420 can be minimized by being discharged from the connection portion between the drying duct 420 and the tab connection pipe 430, which is not completely sealed.

[0167] In the cup washer 1000 according to one embodiment of the present invention, the other end of the drying duct 420 is disposed at a position relatively higher than the maximum water level of the tab 100. That is, the position where the drying duct 420 and the tab connection pipe 430 are coupled is disposed at a position higher than the maximum water level of the tab 100.

[0168] As described above, since the tab 100 and the tab connection pipe 430 are connected via the tab connector 431, it is possible for the washing water to flow into the tab connection pipe 430 up to the same height as the water level in the tab 100.

[0169] In this case, since it is necessary to suppress the washing water from flowing into the drying duct 420 beyond the tab connection pipe 430, it is desirable that the position where the drying duct 420 and the tab connection pipe 430 are connected be disposed at a position higher than the maximum water level in the tab 100.

[0170] Thus, in the cup washer 1000 according to one embodiment of the present invention, by disposing the position where the drying duct 420 and the tab connection pipe 430 are coupled at a position relatively higher than the maximum water level in the tab 100, the washing water flowing into the drying duct 420 at the maximum water level in the tab 100 can be minimized.

[0171] In the cup washer 1000 according to one embodiment of the present invention, the other end of the drying duct 420 can be disposed at a position relatively lower than the outside air inlet 401. That is, the position where the drying duct 420 and the tab connection pipe 430 are coupled can be disposed at a position lower than the outside air inlet 401.

[0172] As described above, when an unintended abnormal situation occurs, since the washing water may be discharged from the connection portion between the drying duct 420 and the tab connection pipe 430, there is a possibility that the washing water discharged in this way may flow into the outside air inlet 401.

[0173] In this case, since problems such as damage or performance degradation of the blower fan 410 may occur due to the washing water, it is necessary to suppress the washing water discharged from the connection portion between the drying duct 420 and the tab connection pipe 430 from flowing into the outside air inlet 401.

[0174] Therefore, for example, even if the washing water is discharged to the corresponding part, it is desirable to arrange the position where the drying duct 420 and the tab connection pipe 430 are joined at a position lower than the outside air inlet 401 to minimize the inflow of the washing water into the outside air inlet 401.

[0175] Thus, in the cup washer 1000 according to an embodiment of the present invention, by arranging the position where the drying duct 420 and the tab connection pipe 430 are joined at a position relatively lower than the outside air inlet 401, in an unintended situation, when the washing water is discharged from the connection portion between the drying duct 420 and the tab connection pipe 430, the inflow of the washing water into the outside air inlet 401 can be minimized.

[0176] The cup washer 1000 according to an embodiment of the present invention may further include a front frame 11 and a rear frame 12.

[0177] The front frame 11 is disposed on the front side of the tab 100, supports the front panel 21, and the rear frame 12 is disposed on the rear side of the drying unit 400 and supports the rear panel 22.

[0178] That is, the front frame 11 and the rear frame 12 form the framework of the cup washer 1000, and the main components of the cup washer 1000 can be supported by the front frame 11 and the rear frame 12.

[0179] In this case, the front frame 11 may be arranged as a pair on the front side of the tab 100, and the rear frame 12 may be arranged as a pair on the rear side of the drying part 400. Further, the front frame 11 and the rear frame 12 are coupled to separate frame structures, and the loads applied to each can be dispersed and transmitted.

[0180] Thus, in the cup washer 1000 according to an embodiment of the present invention, by the front frame 11 supporting the front panel 21 and the rear frame 12 supporting the rear panel 22, the cup washer 1000 can be maintained in a stable state with a certain rigidity.

[0181] In the cup washer 1000 according to an embodiment of the present invention, the drying part 400 may be supported by being coupled to the rear frame 12. That is, the drying part 400 may be supported by the rear frame 12 instead of the tab 100.

[0182] As described above, during the washing process, vibrations occur in the washing tab 100, so it is necessary to minimize the transmission of such vibrations to the drying part 400. In this case, when the drying part 400 is supported by the washing tab 100, it is not preferable in that the vibrations of the tab 100 are transmitted to the drying part 400 relatively largely.

[0183] Therefore, it is desirable to minimize the influence of the vibrations of the tab 100 on the drying part 400 by making it possible to support the drying part 400 arranged on the rear side of the tab 100 by the rear frame 12 that supports the rear panel 22.

[0184] Thus, in the cup washer 1000 according to an embodiment of the present invention, by connecting the drying unit 400 to be supported by the rear frame 12, even if the vibration of the tab 100 is transmitted, the drying unit 400 can be maintained in a stable state.

[0185] In the cup washer 1000 according to an embodiment of the present invention, the second assembly 422 is fixed and coupled to the rear frame 12. That is, the drying unit 400 is coupled to the rear frame 12 by fixing the second assembly 422 disposed on the rear side of the drying duct 420 to the rear frame 12.

[0186] As described above, in view of the fact that the drying unit 400 requires frequent inspection and replacement, the drying unit 400 is disposed on the rear side of the cup washer 1000, so that the drying unit 400 can be inspected simply by removing the rear panel 22.

[0187] In this case, by fixing 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 as required, and the drying duct 420 including the first assembly 421 and the second assembly 422 can also be easily assembled and disassembled.

[0188] Thus, in the cup washer 1000 according to an embodiment of the present invention, by fixing the second assembly 422 to the rear frame 12, the drying unit 400 and the rear frame 12 can be easily assembled and disassembled.

[0189] FIGS. 15 and 16 are views showing the air discharge unit 700 in the cup washer 1000 according to an embodiment of the present invention. FIG. 17 is a cross-sectional view of the air discharge unit 700 shown in FIG. 16.

[0190] The cup washer 1000 according to an embodiment of the present invention further includes an air discharge unit 700 installed at the upper end of the tab 100 to discharge the air in the tab 100.

[0191] As described above, when drying the cup C by supplying the air heated from the drying unit 400 to the tab 100, it is necessary to discharge the air that is used for drying and has a relatively low temperature to the outside of the tab 100.

[0192] In this case, since it is not preferable to discharge the washing water remaining in the tab 100 together with the discharged air, it is desirable to adopt a structure that discharges only the air while suppressing the discharge of the washing water.

[0193] Therefore, by providing the air discharge portion 700 at the upper end of the tab 100 and discharging the air at a position above the highest water level in the tab 100, it is possible to discharge only the air without discharging the washing water.

[0194] Thus, in the cup washer 1000 according to an embodiment of the present invention, by discharging the air in the tab 100 through the air discharge portion 700 provided at the upper end of the tab 100, it is possible to discharge the air without being affected by the washing water in the tab 100.

[0195] In the cup washer 1000 according to an embodiment of the present invention, the air discharge portion 700 is connected between the rear surface of the tab 100 and the rear panel 22. That is, an air discharge port 22b is provided in a part of the rear panel 22, and the air in the tab 100 is discharged to the outside of the cup washer 1000.

[0196] Similar to the aforementioned vent 22a, it is desirable to minimize the exposure of the air outlet 22b to the outside, and considering that the air discharged from the cup washer 1000 may give discomfort to the user when it comes into contact with the user, the air outlet 22b may be provided in the rear panel 22.

[0197] Therefore, since the air discharge portion 700 is connected between the rear surface of the tab 100 and the rear panel 22, the air in the tab 100 can be discharged to the rear side of the cup washer 1000 through the rear panel 22.

[0198] Thus, in the cup washer 1000 according to one embodiment of the present invention, by connecting the air discharge portion 700 between the rear surface of the tab 100 and the rear panel 22, it is possible to minimize the exposure of the discharged air to the user.

[0199] In the cup washer 1000 according to one embodiment of the present invention, the portion of the air discharge portion 700 connected to the tab 100 can be disposed at a relatively lower position than the portion connected to the rear panel 22.

[0200] As described above, for example, even when the discharge portion 700 is disposed at the upper end of the tab 100 so that the washing water is not discharged to the discharge portion 700, in some cases, in situations such as water splash, the washing water may flow into the discharge portion 700.

[0201] The portion where the discharge portion 700 is connected to the tab 100 is provided at a relatively lower position than the portion where the discharge portion 700 is connected to the rear panel 22, and it is desirable that the washing water flowing into the discharge portion 700 is returned to the tab 100 again.

[0202] Thus, in the cup washer 1000 according to one embodiment of the present invention, by disposing the position where the air discharge portion 700 is connected to the tab 100 at a relatively lower position than the position where the air discharge portion 700 is connected to the rear panel 22, for example, even if the washing water flows into the air discharge portion 700, the washing water in the tab 100 can be returned to the tab 100.

[0203] In the cup washer 1000 according to one embodiment of the present invention, the air discharge portion 700 may include a water barrier 710 formed along a direction intersecting the longitudinal direction.

[0204] As described above, for example, even if the cleaning water flowing into the air discharge section 700 is recovered by varying the heights at both ends of the air discharge section 700, there still remains a risk that a certain amount of cleaning water will be discharged to the outside through the air discharge section 700.

[0205] Therefore, it is desirable to form a step such as the water barrier 710 in the longitudinal direction of the air discharge section 700 to prevent the cleaning water flowing into the air discharge section 700 from being blocked by the water barrier 710 and discharged to the outside.

[0206] Thus, in the cup washer 1000 according to an embodiment of the present invention, by forming the water barrier 710 on the air discharge path of the air discharge section 700, it is possible to minimize the discharge of the cleaning water flowing into the air discharge section 700 to the outside.

[0207] The cup washer 1000 according to an embodiment of the present invention can include the tab 100 and the drying section 400. In this case, the drying section 400 can include a blower fan 410, a drying duct 420, and a tab connection pipe 430.

[0208] Specifically, the tab 100 may include a space for cleaning the cup C accommodated therein.

[0209] The drying section 400 can be arranged behind the tab 100 in a state where a part of it is connected to the rear surface of the tab 100, and can heat the incoming outside air and supply it into the tab 100.

[0210] The blower fan 410 can suck the outside air from the outside air inlet 401 and blow the outside air toward the tab 100.

[0211] The drying duct 420 may include a first assembly 421 having one end coupled to the blower fan 410 and covering the front side of the internal flow path F10, and a second assembly 422 coupled to the first assembly 421 and covering the rear side of the internal flow path F10.

[0212] The tab connection pipe 430 may be provided with an integrated tubular form (tubular body) extending from the other end of the drying duct 420 and may be connected to the rear surface of the tab 100 via a tab connector 431 provided at its end.

[0213] As described above, a specific embodiment of the present invention has been described and illustrated. However, the present invention is not limited to the described embodiment, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the technical idea and scope of the present invention. Therefore, such modifications or changes should not be individually understood from the technical concept and perspective of the present invention, and the modifications and changes should be regarded as being included in the scope of the claims of the present invention.
