Description

[Technical field]

[0001] The present invention relates to a cup washer, and more particularly to a cup washer for cleaning cups carried by a user. [Background technology]

[0002] The material discussed herein is merely intended to provide background information regarding the present invention and may not constitute prior art.

[0003] In recent years, in order to prevent environmental pollution, beverage counters have refrained from providing disposable cups to customers, and there has been an increasing trend for customers visiting the counter to carry reusable cups such as tumblers and fill their beverages in the reusable cups.

[0004] In order to provide convenience to customers, i.e., users of reusable cups, it is necessary to provide a cup washer for washing the cups carried by users at the point of sale, so that the users can conveniently wash the cups they carry.

[0005] Therefore, cup washers that can wash cups carried by users can be installed in sales areas to provide users with the convenience of washing their own cups. These cup washers must have a structure that allows anyone to use them easily.

[0006] Related prior art is disclosed in Korean Patent Publication No. 10-2020-0016470.

[0007] The cleaning process can be broadly divided into a cleaning step in which water is sprayed into the cup to clean it, and a rinsing step in which clean water is sprayed into the cup after cleaning with water to rinse it.

[0008] For clean washing, it is necessary to mix detergent into water for washing, and it is necessary to mix rinse into water for rinsing.

[0009] However, the prior art only discloses a method for cleaning a cup using steam. In particular, the prior art discloses a method for cleaning a cup without using detergent. Therefore, the prior art does not suggest a method for cleaning a cup using detergent at all.

[0010] When using a cup washer to wash cups, it is necessary to inject detergent and rinse into the washing section in order to thoroughly wash the cups. Therefore, the cup washer needs to be equipped with a device for injecting detergent and rinse into the washing section.

[0011] In addition, for the convenience of the user, the detergent injection device and the rinse injection device should be provided so that the detergent and rinse are injected into the washing section at the appropriate timing as the washing process is performed, without the user having to operate them manually.

[0012] In addition, detergent is a substance used to clean foreign matter remaining in the cup, and rinse is a substance used to rinse the detergent remaining in the cup after the cup has been cleaned with detergent.

[0013] Therefore, it is necessary to provide a detergent injection device and a rinse injection device so that the path through which the detergent is injected into the washing section and the path through which the rinse is injected into the washing section are separated.

[0014] In addition, in order to ensure smooth washing and rinsing, the cup washer must be provided with a structure that allows the washing water to be effectively mixed with the detergent or rinse. Summary of the Invention [Problem to be solved by the invention]

Effect of the Invention

[0046] In the cup washer of the present invention, the washing section may include a detergent injection device and a rinse injection device disposed separately from each other outside the tub. The water flowing into the tub by the detergent injection device and the rinse injection device can be mixed with the detergent or rinse.

[0047] Therefore, when spraying water to wash a cup, the washing efficiency of the cup can be increased by spraying the washing water, which is a mixture of water and detergent, onto the cup, and when rinsing the cup after washing it, the washing water, which is a mixture of water and rinse, onto the cup, so that the cup can be effectively rinsed.

[0048] In addition, in the cup washer of the present invention, the detergent pump and the rinse pump are connected to a controller provided in the cup washer and can be operated at a time set by the controller to inject detergent or rinse into the tub so that it can be mixed with water in the tub. An administrator can periodically replenish the detergent and rinse in the detergent storage and rinse storage.

[0049] Therefore, a user who wishes to wash his / her own cup does not need to perform a separate operation to add detergent and rinse to water, and can conveniently use detergent to increase the efficiency of washing the cup, and after washing the cup, can rinse the cup thoroughly using rinse.

[0050] In the cup washer of the present invention, the rinse may flow into the tub through the second connecting pipe, the three-way connecting part, the first connecting pipe, and the wash water inlet. Meanwhile, the detergent may flow into the tub through a detergent inlet connected through a separate pipe. Also, the detergent and the rinse may flow into the tub at different times.

[0051] This structure separates the paths through which the detergent and rinse are injected into the tub, preventing the detergent and rinse from mixing with each other, thereby improving the efficiency of the washing and rinsing operations of the cup washer.

[0052] In addition, in the cup washer of the present invention, water and rinse can flow together in one pipe and flow into the tub through the detergent inlet, so that the water and rinse can be mixed more uniformly while flowing, and the washing water, which is a uniform mixture of water and rinse, can be sprayed into the cup, thereby rinsing the cup effectively.

[0053] In addition, in the cup washer of the present invention, the rack may include a first flow path guide portion for guiding the flow direction of water at a position adjacent to the wash water inlet of the tub. As a result, the water flowing into the tub can flow toward the detergent flowing into the tub by the first flow path guide portion. As a result, the flowing water mixes with the detergent, and the water and the detergent can be smoothly mixed with each other, thereby improving the washing efficiency of the cup washer.

[0054] The above-mentioned effects and specific effects of the present invention will be described in conjunction with the following description of the preferred embodiment of the invention. [Brief description of the drawings]

[0062] Fig. 1 is a perspective view of a cup washer according to an embodiment of the present invention, and Fig. 2 is a view of Fig. 1 as seen from another direction.

[0063] The cup washer according to the embodiment can be installed in a sales point that serves beverages. The user of the cup washer can be a customer who buys and drinks beverages. In recent years, in order to protect the environment, restrictions have been imposed on providing disposable cups to customers at sales points, and the scope of these restrictions is expanding.

[0064] Therefore, a cup washer may be provided at the service counter so that a user carrying a reusable cup can wash the cup at the service counter and use it. The cup to be washed may be a reusable cup such as a tumbler carried by the user. Therefore, the cup washer may have a structure that is convenient for the user to use.

[0065] A washing unit 130 for receiving and washing cups may be provided at an upper portion of the cup washer. The washing unit 130 may be opened and closed by a door 150. At this time, the door 150 may be hingedly rotated in the vertical direction of the cup washer to open and close the washing unit 130.

[0066] With this structure, a user can open the door 150 by hand without bending over, place a cup in the washing section 130, and then operate the cup washer after closing the door 150, thereby conveniently washing the cup.

[0067] The height of the washing unit 130 in the cup washer needs to be appropriately adjusted to fit the body of an adult so that a user can use the cup washer without bending over. Also, the cup washer needs to be provided with a relatively small volume to improve space efficiency.

[0068] For this reason, the cup washer may have a tower-type shape with a relatively small planar cross-sectional area and a relatively long vertical length. Due to the tower-type shape, the cup washer requires that components with a relatively large volume be arranged in the vertical direction.

[0069] In addition, due to the tower-type shape, there is a risk that the cup washer may tip over. In order to prevent the cup washer from tipping over, it is necessary to lower the overall center of gravity by arranging parts with a relatively large load at the bottom.

[0070] The structure of the cup washer will be described in more detail below with reference to the drawings. Figure 3 is a diagram showing a state in which the door 150 of the cup washer according to an embodiment is open. Figure 4 is a perspective view showing the cup washer with some parts omitted. Figure 5 is a side view of Figure 4.

[0071] In one embodiment, the cup washer may include a base plate 110 , a reservoir 120 , a washing section 130 , a mid-plate 140 , a door 150 , and a frame 160 .

[0072] The base plate 110 is disposed at the lowest part of the cup washer and can support other parts of the cup washer. The lower part of the base plate 110 may be placed on the ground. The base plate 110 may include a first part 111 and a second part 112. The lower surface of the first part 111 may be placed on the ground and can support the second part 112.

[0073] The second part 112 may be disposed on an upper portion of the first part 111, and may have the water tank 120 disposed therein. A frame 160 may be coupled to the second part 112. For example, a front supporter 161, a rear supporter 162, and an intermediate supporter 163 may be coupled to the second part 112. Thus, the frame 160 can be supported by the second part 112.

[0074] The water tank 120 is disposed above the base plate 110 and can store water for washing cups. The water tank 120 can be connected to a city water supply via piping. Thus, water from the city water supply can flow into the water tank 120 and be stored therein. The water tank 120 can also be connected to the washing unit 130 via piping. Thus, the water from the water tank 120 can flow into the washing unit 130 and be used to wash cups accommodated in the washing unit 130.

[0075] A heating device may be provided inside the water tank 120. The water in the water tank 120 can be heated by the heating device and then flow into the cleaning unit 130. This allows the cups to be washed using the heated water, thereby improving the efficiency of washing the cups.

[0076] The water tank 120 can be filled with water. Thus, the water tank 120 when filled with water may have a relatively large load compared to other components. The water tank 120 may be placed on the base plate 110 and disposed at the bottom of the cup washer.

[0077] The overall center of gravity of the cup washer may be lowered due to the weight of the water tank 120 filled with water placed at the bottom of the cup washer, so that the cup washer, which is installed in a tower type with a relatively long vertical length, is able to maintain a stable state without easily tipping over even when subjected to external impact.

[0078] The washing unit 130 is disposed on the water tank 120 and can wash the cups contained therein. A space for accommodating the cups may be formed in the washing unit 130. The washing unit 130 may be connected to the water tank 120 by a pipe. Thus, water for washing can flow from the water tank 120 into the washing unit 130.

[0079] In another embodiment, the washing unit 130 may be directly connected to the water supply without passing through the water tank 120. Thus, the user can choose to wash the cup using water flowing from the water tank 120 or water flowing directly from the water supply.

[0080] The intermediate plate 140 is disposed between the water tank 120 and the cleaning unit 130 and can support the cleaning unit 130. The cleaning unit 130 is disposed on the intermediate plate 140 and can support a part of the load of the cleaning unit 130. The intermediate plate 140 has an approximately plate-like shape and may be coupled to the frame 160 at its edges and supported by the frame 160.

[0081] The door 150 is disposed above the washing unit 130 and can be hinged in the vertical direction to open and close the open upper portion of the washing unit 130. Referring to Fig. 3, the door 150 can be hinged in the vertical direction of the cup washer. Thus, a user can manually open the door 150, place the cup 10 inside the washing unit 130, and then close the door 150 to wash the cup 10.

[0082] A top cover 210 may be provided on the upper end of the cleaning unit 130. A part of the top cover 210 may be coupled to the upper edge portion of the cleaning unit 130, and the door 150 may be placed thereon.

[0083] An inlet cover 213 may be provided on yet another part of the top cover 210. The inlet cover 213 can open and close an inlet for detergent and rinse to be put into the cleaning unit 130, and can be provided on the top cover 210 so as to be detachable.

[0084] A user can open and close the door 150 at the top of the dishwasher to put cups in the washing section 130 or remove cups from the washing section 130. At this time, since the door 150 rotates on a hinge in the vertical direction, the user can move the door 150 conveniently without bending over.

[0085] In addition, by rotating the door 150 on a hinge, the area occupied by the cup washer when viewed from above can be kept constant even when the door 150 is open. As a result, the planar cross-sectional area of ​​the cup washer remains constant whether the door 150 is open or closed, eliminating the need for additional space to open the door 150.

[0086] In the embodiment, the cup is hinged at the top of the washing unit 130 so that it can be rotated in the vertical direction of the cup washer, allowing the user to conveniently use the cup washer by opening and closing the door 150 without bending over. In addition, this structure eliminates the need for additional space to open the door 150, improving space efficiency.

[0087] The frame 160 is supported by the base plate 110 and is coupled to the intermediate plate 140 to support the cleaning unit 130. The frame 160 defines an internal space of the cup washer, in which various components can be coupled and supported.

[0088] The frame 160 may include a front supporter 161, a rear supporter 162, a middle supporter 163, and an upper supporter 164. Each component part of the frame 160 can support the load of the washing unit 130, the door 150, and the like provided at the top of the cup washer.

[0089] The front supporters 161 may be disposed in a pair spaced apart from each other at the front of the cup washer, with their lower portions connected to the base plate 110 and their lengths disposed in the up-down direction. The pair of front supporters 161 may be disposed in front of the cup washer at positions spaced apart from each other in the lateral direction of the cup washer to form a front corner portion of the cup washer.

[0090] The front supporter 161 may have an L-shaped cross section to form a corner of the cup washer. The front supporter 161 may be connected to the base plate 110 by a connecting device such as a wood screw.

[0091] The rear supporters 162 may be arranged in a pair spaced apart from each other at the rear of the cup washer, with their lower portions connected to the base plate 110 and their lengths arranged in the up-down direction. The pair of rear supporters 162 may be arranged at positions spaced apart from each other in the lateral direction of the cup washer at the rear of the cup washer, adjacent to rear corners of the cup washer. The rear supporters 162 may be connected to the base plate 110 by a connecting device.

[0092] The intermediate supporters 163 may be arranged in a pair spaced apart from each other, between the front supporter 161 and the rear supporter 162, with their lower parts connected to the base plate 110 and their length arranged in the up-down direction. The pair of intermediate supporters 163 may be arranged in positions spaced apart from each other in the lateral direction of the cup washer in the center of the cup washer.

[0093] The middle supporter 163 can be connected to the base plate 110 by a connecting device. Also, the middle supporter 163 can be connected to the middle plate 140 and the upper supporter 164 by a connecting device to stably maintain its position and support the load of the parts of the cup washer.

[0094] The upper supporters 164 may be arranged above the intermediate supporter 163, arranged in a pair spaced apart from each other in the lateral direction, arranged in the longitudinal direction, and connected to the cleaning unit 130. The pair of upper supporters 164 may be arranged at positions spaced apart from each other in the lateral direction of the cup washer from the top of the cup washer.

[0095] The cleaning unit 130 may be coupled to the upper supporter 164 by a coupling device. Thus, the upper supporter 164 can support the weight of the cleaning unit 130.

[0096] A plurality of upper supporters 164 may be provided at a distance from each other in the vertical direction of the cup washer. Thus, in Fig. 5 and other figures, an embodiment is shown in which a pair is provided on each side of the cup washer and a pair is provided above and below the cup washer, for a total of four upper supporters. However, the number of upper supporters 164 is not limited to this.

[0097] Each of the upper supporters 164 may be connected to the front supporter 161, the rear supporter 162, and the intermediate supporter 163. Therefore, the load of the cleaning unit 130 may be transmitted to the front supporter 161, the rear supporter 162, and the intermediate supporter 163 via the upper supporter 164, and finally transmitted to the base plate 110.

[0098] With this structure, the cup washer can stably support the cleaning unit 130 provided therein. The upper supporter 164 may be connected to the front supporter 161, the rear supporter 162, and the middle supporter 163 by a connecting device such as a wood screw.

[0099] In the embodiment, the parts provided on the upper part of the cup washer, including the washing unit 130, are supported by the frame 160, and each part can be ultimately supported by the base plate 110. With this structure, even when a relatively heavy part such as the washing unit 130 is provided on the upper part of the cup washer, each part can be stably supported by the frame 160 and the base plate 110.

[0100] The cup washer may include a front panel 170 and a rear panel 180. The front panel 170 may be disposed at the front of the cup washer and cover the water reservoir 120 and the washing section 130. The front panel 170 may be coupled to the rear supporter 162 of the frame 160 by a coupling device.

[0101] The rear panel 180 may be coupled to the frame 160 to cover the rear of the cup washer. The rear panel 180 may be provided with a first ventilation hole 181 for allowing ventilation between the inside and outside of the cup washer. Air flowing into the drying module 132 described below may flow into the inside of the cup washer through the first ventilation hole 181.

[0102] The rear panel 180 may have a handle 260 coupled thereto by which a user or administrator may pick up the cup washer for easy access to the cup washer.

[0103] The cup washer may include a display unit 190 coupled to an upper portion of the rear supporter 162 and disposed on one side of the door 150. The display unit 190 may be disposed on one side of the door 150 and protrude from the door 150.

[0104] Thus, a user can face the front of the cup washer toward the display unit 190. The display unit 190 can display various information regarding the use of the cup washer in the form of images, text, and videos.

[0105] A user can operate the cup washer or know the operating status of the cup washer by looking at the information displayed on the display unit 190. The display unit 190 may also include a command input means, for example, inputted by electrostatic touch. Thus, the user can control the operation of the cup washer using the display unit 190.

[0106] The cup washer may include a first circuit board unit 220 and a board unit supporter 230. The first circuit board unit 220 may be disposed on one side of the water tank 120 and include a control unit that controls the operation of the cup washer. The first circuit board unit 220 may be disposed on one side of the water tank 120 below the cup washer where extra space is generated due to the water tank having a relatively smaller volume than the washing unit 130.

[0107] The substrate supporter 230 may have a lower portion connected to the base plate 110, an upper portion connected to the middle plate 140, and a first circuit substrate portion 220. The substrate supporter 230 may be stably connected to the base plate 110 by a connecting device.

[0108] The board supporter 230 can be used not only to secure the first circuit board unit 220 but also to secure the piping arranged at the bottom of the cup washer.

[0109] The cup washer may include an exterior portion 250 that couples to the rear panel 180 and covers the rear supporter 162. The rear supporter 162 may have a number of fasteners coupled thereto for coupling to other components of the cup washer.

[0110] Therefore, if the rear supporter 162 fastened by the fastening device is exposed to the outside, the visual aesthetics of the cup washer may be compromised. Therefore, a structure that covers the rear supporter 162 fastened by the fastening device is required.

[0111] The exterior part 250 covers the rear supporter 162 and may have a relatively small number of fasteners attached thereto compared to the rear supporter 162. With this structure, the exterior part 250 is disposed on the outside of the cup washer at a position corresponding to the rear supporter 162, allowing the cup washer to have a clean overall appearance.

[0112] Hereinafter, a specific structure of the cleaning unit 130 will be described in detail with reference to the drawings. Figure 6 is a perspective view of the cleaning unit 130 according to an embodiment. Figure 7 is a front view of the cleaning unit 130 according to an embodiment.

[0113] Fig. 8 is a side view of the cleaning unit 130 according to an embodiment. Fig. 9 is a rear view of the cleaning unit 130 according to an embodiment. The cleaning unit 130 may include a tub 131, a drying module 132, a sump 133, a circulation pump 134, and a drain pump 135.

[0114] The tub 131 provides a space for accommodating a cup and can spray cleaning water. A rack for placing cups thereon can be provided inside the tub 131, and a spraying means for spraying water can be provided below the rack. The open upper end of the tub 131 can be opened and closed by a door 150.

[0115] The drying module 132 is disposed on one side of the tub 131 so as to be connected to the tub 131, and can inject heated air for drying into the inside of the tub 131. After the cup 10 has been washed with water, moisture remains on the surface of the cup. The drying module 132 can dry the cup by injecting heated air, i.e., hot air, onto the cup to dry the water remaining in the cup.

[0116] The drying module 132 may include a heating device for heating the air flowing into the drying module 132. The drying module 132 may also include a blower fan 1321 for forcibly causing air to flow through a flow path formed in the drying module 132.

[0117] The sump 133 is disposed below the tub 131 so as to be connected to the tub 131, and can store water to be sprayed from the tub 131. The water stored in the sump 133 can be sprayed by a spray device in the tub 131 while circulating between the tub 131 and the sump 133 by a circulation pump 134, to wash the cup 10 accommodated in the tub 131.

[0118] The circulation pump 134 is disposed below the tub 131 so as to be connected to the tub 131 and the sump 133, and is capable of circulating water between the tub 131 and the sump 133. The circulation pump 134 is capable of forcing water to flow from the sump 133 to the tub 131.

[0119] The circulation pump 134 may be connected to a spray device disposed under the tub 131. Thus, when the circulation pump 134 operates, the water stored in the sump 133 flows into the spray device and is sprayed by the spray device into the inside of the tub 131 to wash the cup.

[0120] The drain pump 135 is disposed below the tub 131 so as to be connected to the sump 133, and can discharge water from the sump 133 to the outside. When the washing of the cups with water is completed, the drain pump 135 is operated so that the water stored in the sump 133 can be discharged to the outside of the cup washer through a drain pipe connected to the drain pump 135.

[0121] The process of rinsing the cup 10 with the water stored in the water tank 120 is as follows. Water may flow from the water supply through piping into the water tank 120 and be stored therein. The water in the water tank 120 may be heated by a heating device provided in the water tank 120. The heated water in the water tank 120 may flow into the inside of the tub 131 through piping and be stored in the sump 133 disposed below the tub 131.

[0122] When the circulation pump 134 is operated to wash the cups, the hot water passes from the sump 133 through the sprayer and can be sprayed into the inside of the tub 131 to wash the cups. The hot water sprayed into the tub 131 can then flow further into the sump 133, and be further pumped by the circulation pump 134 into the sprayer, where it can be sprayed into the inside of the tub 131.

[0123] While the circulation pump 134 is operating, the hot cleaning water flows through the sump 133, the sprayer, and the tub 131 in sequence, and these flows can be repeated. Once the cups have been washed with hot water, the circulation pump 134 can be stopped and the drain pump 135 can be operated to drain the water stored in the sump 133 to the outside.

[0124] When drainage by the drain pump 135 is completed, the drying module 132 operates to inject hot air into the inside of the tub 131, and after the hot air is injected for a set time, the cup cleaning operation including the drying process can be completed.

[0125] The cup washer can perform both washing using a detergent and rinsing using a rinse. The following describes in detail the structure provided for putting the detergent and rinse into the tub.

[0126] Meanwhile, in the process of washing the cup with hot water, the washing process using detergent and the rinsing process using rinse can be separated from each other. After the process of washing the cup by mixing the detergent with hot water is completed, the water in the sump 133 contains detergent and foreign matter. Therefore, the contaminated water can be discharged to the outside by operating the drain pump 135.

[0127] After the contaminated water is discharged to the outside, warm water is introduced into the sump 133, and rinse is performed by mixing the warm water with rinse and operating the circulation pump 134. In this manner, the cleaning process using detergent and the rinsing process using rinse can be separated, thereby improving the cleaning efficiency of the cup washer.

[0128] The cleaning section 130 may include a detergent reservoir 136 , a rinse reservoir 137 , a detergent inlet 138 , a rinse inlet 139 , a detergent pump 1301 , and a rinse pump 1302 .

[0129] The detergent storage section 136 is disposed behind the tub 131 and can store a detergent. The rinse storage section 137 is disposed behind the tub 131 separately from the detergent storage section 136 and can store a rinse. Therefore, the detergent and the rinse may not be mixed with each other.

[0130] The top cover 210 may be provided with a detergent inlet 211 into which a detergent is introduced, and a rinse inlet 212 into which a rinse is introduced. The detergent inlet 211 may be connected to the detergent storage unit 136, and the rinse inlet 212 may be connected to the rinse storage unit 137. Thus, the detergent and rinse that flow into the detergent inlet 211 and the rinse inlet 212 may be stored in the detergent storage unit 136 and the rinse storage unit 137.

[0131] The detergent injector 138 may be connected to the detergent reservoir 136 and the tub 131 to inject detergent into the tub 131. An inlet of the detergent injector 138 may be connected to the detergent reservoir 136 and an outlet of the detergent injector 138 may be connected to the tub 131.

[0132] The rinse inlet 139 may be connected to the rinse reservoir 137 and the tub 131 to inject rinse into the tub 131. An inlet of the rinse inlet 139 may be connected to the rinse reservoir 137 and an outlet of the rinse inlet 139 may be connected to the tub 131.

[0133] The detergent pump 1301 is connected to the detergent injector 138 and can pump the detergent into the tub 131. The rinse pump 1302 is connected to the rinse injector 139 and can pump the rinse into the tub 131. The operations of the detergent pump 1301 and the rinse pump 1302 can be controlled by a control unit.

[0134] The control unit can operate the detergent pump 1301 in the washing process to mix the detergent with water, and can operate the rinse pump 1302 in the rinsing process to mix the rinse with water.

[0135] The water tank 120 may be connected to the tub 131 by a pipe so that the water in the water tank 120 flows into the tub 131. Thus, the water in the water tank 120 may be heated to become hot water, and then flow into the tub 131, and may be stored in the sump 133 until the circulation pump 134 starts operating.

[0136] Meanwhile, as described above, the tub 131 may also include a water supply path that is directly connected to the water supply, so that the cup can be washed or quick washed according to the user's choice.

[0137] The general cleaning uses hot water heated in the water tank 120 to clean the cup, and can use detergent and rinse to clean the cup, but can take a relatively long time.

[0138] The quick wash uses room temperature water supplied from the water supply to wash the cups and does not use detergent or rinse, so the washing time is relatively short, making it convenient for users who want to quickly wash relatively uncontaminated cups.

[0139] Fig. 10 is a diagram showing a detergent injection device and a rinse injection device according to an embodiment. Fig. 11 is a bottom view of the detergent injection device and the rinse injection device. The cup washer may include a washing unit 130 for washing the accommodated cup 10. The washing unit 130 may provide a space for accommodating the cup 10 and include a tub 131 for spraying washing water.

[0140] The cleaning unit 130 may include a detergent injection device that injects detergent into the tub 131, and an injection device that injects rinse into the tub 131. The detergent can be mixed with water and sprayed into the cup to clean the cup. The rinse can be mixed with water and sprayed into the cup to clean the cup and then rinse the cup.

[0141] Thus, after the detergent is used to clean the cup, the rinse can be used to rinse the cup. That is, the detergent and the rinse can be mixed into the water sprayed into the tub 131 at different times. The detergent and the rinse can be provided in liquid form and pumped by the detergent pump 1301 into the inside of the tub 131. The detergent injection device and the rinse injection device may be disposed outside the tub 131.

[0142] The detergent injection device may include a detergent storage unit 136, a detergent injection unit 138, and a detergent pump 1301. The detergent storage unit 136 is disposed on one side of the tub 131 and can store detergent. An administrator can periodically inject detergent into the detergent storage unit 136 to store the detergent in the detergent storage unit 136.

[0143] The detergent injector 138 is coupled to the lower part of the detergent storage part 136, and can inject the detergent in the detergent storage part 136 into the detergent pump 1301. Since the detergent injector 138 is disposed at the lower part of the detergent storage part 136, the detergent can be collected in the detergent injector 138 by gravity and injected into the detergent pump 1301.

[0144] The detergent pump 1301 is connected to the detergent injector 138 and can pump the detergent into the tub 131. The operation of the detergent pump 1301 can be controlled by a control unit provided in the dishwasher. The detergent pump 1301 operates at a set time and can pump the detergent flowing in from the detergent injector 138 into the tub 131.

[0145] The detergent pump 1301 may include a first body 611, a first connector 612, and a detergent discharge part 613. The first body 611 may include therein a motor that provides a pumping force for discharging the detergent, a gear device that connects the motor and a discharge device of the detergent discharge part 613, and the like.

[0146] The first connector 612 is coupled to the first body 611 and connected to the detergent inlet 138, so that the detergent can flow in from the detergent inlet 138. The first connector 612 can connect the detergent inlet 138 and the detergent outlet 613 to each other.

[0147] The detergent discharger 613 has one side connected to the first connector 612 and the other side connected to the tub 131, and can discharge the detergent into the tub 131. A pipe is connected to the other side of the detergent discharger 613, and the detergent discharged from the detergent discharger 613 can be injected into the tub 131 through the pipe.

[0148] The detergent discharge part 613 may include a detergent pumping part 6131 and a detergent injection nozzle 6132. The detergent pumping part 6131 is connected to the first connector 612 and can pump the detergent flowing in from the first connector 612. The detergent pumping part 6131 is driven by a driving force transmitted from a motor provided in the body, and can generate a pumping force to pump the detergent flowing in the first connector 612 to the tub 131.

[0149] The detergent injection nozzle 6132 may be combined with the detergent pumping part 6131 and connected to the tub 131. For example, the detergent injection nozzle 6132 may have a pipe connected to the tub 131 attached to one end thereof. The detergent injection nozzle 6132 may inject detergent into the tub 131. The detergent injection nozzle 6132 may have an inner diameter smaller than the inner diameter of the detergent pumping part 6131 and may be connected to the pipe.

[0150] Fig. 12 is a side view showing a part of the cleaning unit 130. Fig. 13 is a side view seen from the opposite direction to Fig. 12.

[0151] The rinse injection device may include a rinse reservoir 137, a rinse injection device 139, and a rinse pump 1302. With reference to Figures 10 and 11, the detergent injection device and the rinse injection device may have substantially similar external shapes, and some of the components may be arranged symmetrically to each other in the horizontal and vertical directions.

[0152] The rinse reservoir 137 is disposed on one side of the tub 131 separately from the detergent reservoir 136 and can store rinse. An administrator can periodically pour rinse into the rinse reservoir 137 and store the rinse in the rinse reservoir 137.

[0153] The rinse injector 139 is coupled to the lower part of the rinse reservoir 137, and allows the rinse in the rinse reservoir 137 to be injected by the rinse pump 1302. Since the rinse injector 139 is disposed at the lower part of the rinse reservoir 137, the rinse is collected in the rinse injector 139 by gravity, and can be injected by the rinse pump 1302.

[0154] The rinse pump 1302 is connected to the rinse inlet 139 and can pump the rinse into the tub 131. The operation of the rinse pump 1302 can be controlled by a control unit provided in the dishwasher. The rinse pump 1302 operates at a set time and can pump the rinse flowing in from the rinse inlet 139 into the tub 131.

[0155] The rinse pump 1302 may include a second body 621, a second connector 622, and a rinse discharge portion 623. The second body 621 may include therein a motor that provides a pumping force for discharging the rinse, a gear device that connects the motor to a discharge device of the rinse discharge portion 623, and the like.

[0156] The second connector 622 is coupled to the second body 621 and connected to the rinse inlet 139, so that the rinse can flow in from the rinse inlet 139. The second connector 622 can connect the rinse inlet 139 and the rinse outlet 623 to each other.

[0157] The rinse discharge part 623 has one side connected to the second connector 622 and the other side connected to the tub 131, and can discharge rinse into the inside of the tub 131. A pipe is connected to the other side of the rinse discharge part 623, and the rinse discharged from the rinse discharge part 623 can be injected into the inside of the tub 131 through the pipe.

[0158] The rinse discharge part 623 may include a rinse pumping part 6231 and a rinse injection nozzle 6232. The rinse pumping part 6231 is connected to the second connector 622 and can pump the rinse flowing in from the second connector 622. The rinse pumping part 6231 is driven by a driving force transmitted from a motor provided in the body, and can generate a pumping force to pump the rinse flowing in the second connector 622 to the tub 131.

[0159] The rinse injection nozzle 6232 may be combined with the rinse pumping unit 6231 and connected to the tub 131. For example, the rinse injection nozzle 6232 may have a pipe attached to one end thereof, which is connected to the tub 131. The rinse injection nozzle 6232 may inject rinse into the tub 131. The rinse injection nozzle 6232 may be formed with an inner diameter smaller than the inner diameter of the rinse pumping unit 6231, and may be connected to a pipe.

[0160] In an embodiment, the washing unit 130 may have a detergent injector and a rinse injector separately disposed outside the tub 131. The water flowing into the tub 131 by the detergent injector and the rinse injector may be mixed with the detergent or the rinse.

[0161] Therefore, when spraying water to wash a cup, the efficiency of washing the cup can be increased by spraying the washing water, which is a mixture of water and detergent, onto the cup. Also, when rinsing a cup after washing it, the washing water, which is a mixture of water and rinse, onto the cup can be sprayed to effectively rinse the cup.

[0162] In an embodiment, the detergent pump 1301 and the rinse pump 1302 are connected to a controller provided in the cup washer and can be operated at a time set by the controller to inject detergent or rinse into the tub 131 and mix with water in the tub 131. An administrator can periodically replenish the detergent reservoir 136 and the rinse reservoir 137 with detergent and rinse.

[0163] Therefore, a user who wishes to wash his / her own cup does not need to perform a separate operation to add detergent and rinse to water, and can conveniently use detergent to increase the efficiency of washing the cup, and after washing the cup, can rinse the cup thoroughly using rinse.

[0164] Fig. 14 is a perspective view showing the detergent injection section 138 according to an embodiment. Fig. 15 is a view of Fig. 14 seen from another direction. Fig. 16 is a view showing a part of the detergent injection device. Fig. 17 is a view showing a part of the washing section 130.

[0165] The detergent injection unit 138 may include a first lower cover 1381 and a first connection unit 1381. The first lower cover 1381 may be coupled to a lower portion of the detergent storage unit 136 to cover the open lower surface of the detergent storage unit 136. Since the first lower cover 1381 covers the lower surface of the detergent storage unit 136, the liquid detergent stored in the detergent storage unit 136 may descend by gravity and be placed on the upper surface of the first lower cover 1381.

[0166] The first connecting portion 1382 may protrude downward from the first lower cover 1381 and be coupled to the first connector 612, and may be formed with a first flow hole 1382a through which the detergent flows. The detergent placed on the upper surface of the first lower cover 1381 may flow into the first connector 612 through the first flow hole 1382a provided in the first connecting portion 1382.

[0167] First lower cover 1381 may be formed at an angle so that the height of the upper surface decreases toward first flow hole 1382a. Thus, liquid detergent placed on the upper surface of first lower cover 1381 may flow along the upper surface of first lower cover 1381 by gravity and collect at the entrance of first flow hole 1382a, which is located at the lowest position on the oblique upper surface of first lower cover 1381.

[0168] The detergent collected at the entrance of the first flow hole 1382a flows downward through the first flow hole 1382a, passes through the first connector 612, flows into the detergent discharge section 613, is pumped by the detergent pumping section 6131, and can flow into the tub 131 via the detergent injection nozzle 6132 and piping.

[0169] Fig. 18 is a perspective view showing a rinse injection unit 139 according to one embodiment. Fig. 19 is a view seen from another direction of Fig. 18. Fig. 20 is a view showing a part of the rinse injection device.

[0170] The rinse injection unit 139 may include a second lower cover 1391 and a second connection unit 1392. The second lower cover 1391 may be coupled to a lower portion of the rinse storage unit 137 to cover the open lower surface of the rinse storage unit 137. Since the second lower cover 1391 covers the lower surface of the rinse storage unit 137, the liquid rinse stored in the rinse storage unit 137 may descend by gravity and be placed on the upper surface of the second lower cover 1391.

[0171] The second connecting part 1392 may protrude downward from the second lower cover 1391 and be coupled to the second connector 622 to form a second flow hole 1392a through which the rinse flows. The rinse placed on the upper surface of the second lower cover 1391 may flow into the second connector 622 through the second flow hole 1392a provided in the second connecting part 1392.

[0172] The second lower cover 1391 may be formed at an angle such that the height of the upper surface decreases toward the second flow hole 1392a. Thus, the liquid rinse placed on the upper surface of the second lower cover 1391 may flow along the upper surface of the second lower cover 1391 by gravity and collect at the entrance of the second flow hole 1392a, which is located at the lowest position on the inclined upper surface of the second lower cover 1391.

[0173] The rinse that collects at the entrance of the second flow hole 1392a flows downward through the second flow hole 1392a, passes through the second connector 622 and flows into the rinse discharge section 623, is pumped by the rinse pumping section 6231, and can flow into the tub 131 via the rinse injection nozzle 6232 and piping.

[0174] 9, the tub 131 may include a detergent inlet 1312 and a wash water inlet 1315. The detergent inlet 1312 is connected to a detergent injection nozzle 6132 by a pipe, so that the detergent can flow into the tub 131 from the detergent injection nozzle 6132. The detergent discharged from the detergent discharge part 613 can flow into the inside of the tub 131 through the detergent inlet 1312.

[0175] The cleaning water inlet 1315 is disposed above the detergent inlet 1312, allowing water to flow into the tub 131. The cleaning water inlet 1315 is connected to the water tank 120 via a pipe, allowing hot water to flow from the water tank 120 into the tub 131 through the cleaning water inlet 1315.

[0176] Also, rinse can flow into the tub 131 through the cleaning water inlet 1315. This will be described in detail below. Figure 21 is a diagram showing a structure in which piping is connected to the cleaning unit 130.

[0177] The cup washer may include a water tank 120, a first connecting pipe 631, a second connecting pipe 632, and a three-way connecting unit 633. The water tank 120 is disposed below the washing unit 130 and can store water for washing cups.

[0178] The first connecting pipe 631 may connect the cleaning water inlet 1315 and the water tank 120. The water in the water tank 120 may be heated by a heating device and flow into the tub 131 through the first connecting pipe 631 and the cleaning water inlet 1315.

[0179] The second connecting pipe 632 can connect the rinse injection nozzle 6232 and the first connecting pipe 631. The three-way connecting part 633 may be attached to the first connecting pipe 631, and one end of the second connecting pipe 632 may be attached thereto. Thus, the rinse discharged from the rinse injection nozzle 6232 mixes with the water flowing through the first connecting pipe 631 in the three-way connecting part 633, and the water mixed with the rinse can flow into the inside of the tub 131 through the cleaning water inlet 1315.

[0180] With this structure, the rinse discharged from the rinse injection nozzle 6232 flows from the second connecting pipe 632 into the first connecting pipe 631, mixes with the water flowing through the first connecting pipe 631, and can flow into the inside of the tub 131.

[0181] When performing the rinsing operation, first, the water containing the dirt and detergent stored in the sump 133 can be drained to the outside of the cup washer using the drain pump 135. After that, further warm water from the water tank 120 can flow into the tub 131 through the wash water inlet 1315 and be stored in the sump 133 below the tub 131.

[0182] Water stored in sump 133 can be circulated between tub 131 and sump 133 using circulation pump 134 while the water is sprayed into a cup housed inside tub 131 to rinse the cup. When performing these rinsing operations, the water can be mixed with a rinse.

[0183] When water is flowed from the water tank 120 into the tub 131 to fill the sump 133 for rinsing, rinse can be pumped at the same time that water flows into the first connecting pipe 631. At this time, the second connecting pipe 632 through which the rinse flows is connected to the first connecting pipe 631 via the three-way connecting part 633, so that the rinse can mix with the water and flow into the inside of the tub 131.

[0184] The water and rinse in the three-way connection 633 mix and flow together, and as they continue to flow and are stored in the sump 133, the water and rinse may further mix together, resulting in a uniform mixture of water and rinse in the sump 133.

[0185] Meanwhile, the rinse can be used for rinsing the rinse remaining on the surface of the cup after the cleaning operation using the detergent, so the detergent and the rinse must be kept separate and not mixed with each other during the entire process of cleaning the cup.

[0186] Therefore, the tub 131 is formed with a detergent inlet 1312 separate from the cleaning water inlet 1315, and the detergent injection nozzle 6132 and the detergent inlet 1312 may be connected by a separate pipe other than the first connecting pipe 631 or the second connecting pipe 632.

[0187] In the embodiment, the rinse may flow into the tub 131 through the second connecting pipe 632, the three-way connecting part 633, the first connecting pipe 631, and the cleaning water inlet 1315. Meanwhile, the detergent may flow into the tub 131 through the detergent inlet 1312 connected through a separate pipe. Also, the detergent and the rinse may flow into the tub 131 at different times.

[0188] This structure separates the paths through which the detergent and rinse are injected into the tub 131, preventing the detergent and rinse from mixing with each other, thereby improving the efficiency of the washing and rinsing operations of the cup washer.

[0189] In the embodiment, the water and rinse may flow together in one pipe and enter the tub 131 through the detergent inlet 1312. This allows the water and rinse to be mixed more uniformly while flowing, and the washing water, which is a uniform mixture of water and rinse, can be sprayed into the cup to effectively rinse the cup.

[0190] As described above, the cup washer may include the drying module 132, the sump 133, the circulation pump 134, and the drain pump 135. The drying module 132 is disposed at a side portion of the tub 131 so as to be connected to the tub 131, and can inject heated air into the inside of the tub 131. After the above-mentioned cleaning and rinsing operations are performed, the drying module 132 can be operated to dry water remaining on the surface of the cup contained in the tub 131.

[0191] The sump 133 is disposed below the tub 131 so as to be connected to the tub 131, and can store water to be sprayed by the tub 131. The circulation pump 134 is disposed below the tub 131 so as to be connected to the tub 131 and the sump 133, and can circulate water between the tub 131 and the sump 133. By operating the circulation pump 134, water can be circulated and sprayed into the tub 131 to wash or rinse a cup accommodated in the tub 131.

[0192] The drain pump 135 is disposed below the tub 131 so as to be connected to the sump 133, and can discharge water from the sump 133 to the outside. After the washing or rinsing operation is completed, the water stored in the sump 133 can be discharged to the outside of the cup washer via the drain pump 135.

[0193] 15 and 16, the detergent injection part 138 may include a 1-1 cover coupling protrusion 1383, a 1-2 cover coupling protrusion 1384, and a 1-3 cover coupling protrusion 1385. The 1-1 cover coupling protrusion 1383 may protrude from the first lower cover 1381 and be coupled to the tab 131. A coupling protrusion protrudes from the tab 131 at a position corresponding to the 1-1 cover coupling protrusion 1383, and the 1-1 cover coupling protrusion 1383 and the coupling protrusion of the tab 131 may be coupled to each other by a coupling tool such as a wood screw.

[0194] The 1-2 cover coupling protrusion 1384 may protrude from the first lower cover 1381 and be coupled to the first connector 612. The 1-3 cover coupling protrusion 1385 may protrude from the first lower cover 1381 and may have a first insertion groove 1385a formed therein.

[0195] Correspondingly, the first connector 612 may include a first fastening portion 6121 and a first coupling hook 6122. The first fastening portion 6121 may be formed to protrude laterally from the first connector 612 so as to be fastened to the 1-2 cover coupling protrusion 1384.

[0196] The first-second cover coupling protrusion 1384 may include a first large diameter portion 1384a having a relatively large outer diameter, and a first small diameter portion 1384b protruding from the first large diameter portion 1384a and having a relatively small outer diameter. The first large diameter portion 1384a and the first small diameter portion 1384b may have holes formed therein for fastening a coupling device.

[0197] The first fastening portion 6121 of the first connector 612 has a hole formed therein, and the first small diameter portion 1384b of the 1-2 cover coupling protrusion 1384 can be inserted into the hole of the first fastening portion 6121. With the first small diameter portion 1384b inserted into the first fastening portion 6121, the 1-2 cover coupling protrusion 1384 and the first fastening portion 6121 can be coupled to each other by a coupling tool.

[0198] The first coupling hook 6122 can be inserted into the first insertion groove 1385a and coupled with the 1-3 cover coupling protrusion 1385. The first insertion groove 1385a may be formed to have a predetermined length in the vertical direction of the detergent injection part 138. The first coupling hook 6122 can move in the length direction of the first insertion groove 1385a, that is, in the vertical direction of the detergent injection part 138, and be inserted into the first insertion groove 1385a.

[0199] The first coupling hook 6122 may be formed so as not to easily come off the first insertion groove 1385a when facing downward while being inserted into the first insertion groove 1385a. Therefore, the 1-3 cover coupling protrusion 1385 may stably maintain a state coupled to the first connector 612 without a fastening device.

[0200] 17, the detergent pump 1301 may be coupled to the drying module 132. To this end, the first body 611 of the detergent pump 1301 may be provided with a 1-1 module fastening portion 6111, and the drying module 132 may be provided with a 1-2 module fastening portion 132a.

[0201] The 1-1 module fastening portion 6111 may be formed to protrude in a lateral direction of the first body 611 and be fastened to the drying module 132. Correspondingly, the 1-2 module fastening portion 132a may protrude from the drying module 132 toward the 1-1 module fastening portion 6111 and be fastened to the 1-1 module fastening portion 6111. The 1-1 module fastening portion 6111 and the 1-1 module fastening portion 6111 may be coupled to each other by a coupling device.

[0202] Thus, a portion of the detergent injection device can be coupled to the tub 131, and another portion can be coupled to the drying module 132. With such a structure, the drying module 132 is disposed between the tub 131 and the detergent injection device, and the drying module 132 and the detergent injection device may be disposed so as to at least partially overlap each other.

[0203] This reduces the space required for arranging the drying module 132 and the detergent injection device, thereby improving the space efficiency of the cup washer. In addition, since the detergent injection device is coupled to both the drying module 132 and the tub 131, the coupling between the detergent injection device, the drying module 132 and the tub 131 can be made firm.

[0204] 19 and 20, the rinse injection part 139 may include a 2-1 cover coupling protrusion 1393, a 2-2 cover coupling protrusion 1394, and a 2-3 cover coupling protrusion 1395. The 2-1 cover coupling protrusion 1393 may protrude from the second lower cover 1391 and be coupled to the tab 131. A coupling protrusion protrudes from the tab 131 at a position corresponding to the 2-1 cover coupling protrusion 1393, and the 2-1 cover coupling protrusion 1393 and the coupling protrusion of the tab 131 may be coupled to each other by a coupling tool such as a wood screw.

[0205] The 2-2 cover coupling protrusion 1394 may protrude from the second lower cover 1391 and be coupled to the second connector 622. The 2-3 cover coupling protrusion 1395 may protrude from the second lower cover 1391 and may have a second insertion groove 1395a formed therein.

[0206] Correspondingly, the second connector 622 may include a second fastening portion 6221 and a second coupling hook 6222. The second fastening portion 6221 may be formed to protrude laterally from the second connector 622 so as to be fastened to the cover coupling protrusion 1394 of 2-2.

[0207] The 2-2 cover coupling protrusion 1394 may include a second large diameter portion 1394a having a relatively large outer diameter, and a second small diameter portion 1394b protruding from the second large diameter portion 1394a and having a relatively small outer diameter. The second large diameter portion 1394a and the second small diameter portion 1394b may have holes formed therein for fastening a coupling device.

[0208] The second fastening portion 6221 of the second connector 622 has a hole formed therein, and the second small diameter portion 1394b of the 2-2 cover coupling protrusion 1394 can be inserted into the hole of the second fastening portion 6221. With the second small diameter portion 1394b inserted into the second fastening portion 6221, the 2-2 cover coupling protrusion 1394 and the second fastening portion 6221 can be coupled to each other by a coupling tool.

[0209] The second coupling hook 6222 can be inserted into the second insertion groove 1395a and coupled to the 2-3 cover coupling protrusion 1395. The second insertion groove 1395a may be formed to have a predetermined length in the vertical direction of the rinse injection part 139. The second coupling hook 6222 can move in the length direction of the second insertion groove 1395a, that is, in the vertical direction of the rinse injection part 139, and be inserted into the second insertion groove 1395a.

[0210] The second coupling hook 6222 may be formed so as not to easily come off the second insertion groove 1395a when facing downward while inserted into the second insertion groove 1395a. Therefore, the 2-3 cover coupling protrusion 1395 may stably maintain a state coupled to the second connector 622 without a fastening tool.

[0211] 17, the rinse pump 1302 may be coupled to the drying module 132. To this end, the second body 621 of the rinse pump 1302 may be provided with a 2-1 module fastening portion 6211, and the drying module 132 may be provided with a 2-2 module fastening portion 132b.

[0212] The 2-1 module fastening portion 6211 is formed to protrude in a lateral direction of the second body 621 and can be fastened to the drying module 132. Correspondingly, the 2-2 module fastening portion 132b may protrude from the drying module 132 toward the 2-1 module fastening portion 6211 and be fastened to the 2-1 module fastening portion 6211. The 2-1 module fastening portion 6211 and the 2-1 module fastening portion 6211 can be coupled to each other by a coupling device.

[0213] Thus, a portion of the rinse injection device can be coupled to the tub 131, and another portion can be coupled to the drying module 132. With such a structure, the drying module 132 is disposed between the tub 131 and the rinse injection device, and the drying module 132 and the rinse injection device may be disposed such that they at least partially overlap each other.

[0214] This reduces the space required for arranging the drying module 132 and the rinse injection device, thereby improving the space efficiency of the cup washer. Also, since the rinse injection device is coupled to both the drying module 132 and the tub 131, the coupling between the rinse injection device, the drying module 132, and the tub 131 can be made firm.

[0215] 22 is a side view of a portion of a rack 400 according to an embodiment. The wash water inlet 1315 may be disposed at a position spaced apart from the detergent inlet 1312 and disposed above the detergent inlet 1312. Thus, the water flowing into the wash water inlet 1315 does not mix with the detergent flowing into the tub 131, and the water flows into the sump 133 below the tub 131. Similarly, after the detergent flows into the sump 133, the detergent and water may be mixed together.

[0216] Since the flow of water stored in sump 133 is somewhat sluggish, when the water and detergent mix in sump 133, the water may not mix well with the detergent.

[0217] Therefore, in order to improve the mixing efficiency, it is necessary to make the water and detergent mix with each other near the inlets through which the water and detergent flow into the tub 131. At the inlet of the tub 131, the water flows particularly vigorously, so if the water and detergent are mixed near the inlets of the tub 131, the detergent can be mixed with the water smoothly. Such a structure will be described below.

[0218] The tub 131 may include a cleaning water inlet 1315 and a detergent inlet 1312. The cleaning water inlet 1315 and the detergent inlet 1312 may be formed at a rear portion of the tub 131. The detergent inlet 1312 may be formed to penetrate one side of the tub 131 and serve as a passage through which detergent flows into the tub 131. The cleaning water inlet 1315 may be disposed above the detergent inlet 1312 and serve as a passage through which water flows into the tub 131.

[0219] The cleaning unit 130 may include a rack 400. The rack 400 is provided inside the tub 131, and may be formed by mounting cups thereon and connecting the rack 400 with a plurality of wires. For example, cups, cup lids, straws, etc. may be placed on the rack 400.

[0220] At this time, the cup may be placed upside down on the rack 400. That is, the open inlet of the cup may be placed at the bottom of the rack 400, and the bottom of the cup may be placed at the top of the rack 400. In this way, water sprayed from the bottom of the rack 400 in an upward direction can smoothly flow into the inside of the cup to clean the inside of the cup.

[0221] The rack 400 may be generally connected to each other with wires to form a three-dimensional mesh structure. Due to this shape, cups and the like can be easily placed on the rack 400, and the sprayed water passes through the bottom of the rack 400, making it easy to wash the cups and the like placed on the rack 400.

[0222] The rack 400 may include a bottom 410. The bottom 410 is seated on the bottom of the tub 131 and can support the cups seated on the rack 400 from below. In order to stably support the cups, the bottom 410 may be provided in a shape that is widely open in the front, back, left and right directions of the tub 131.

[0223] The bottom 410 may include an edge 411, a first inclined portion 412, and a first bent portion 413. The edge 411 forms an edge of the bottom 410, and may be formed such that a portion of the edge 411 protrudes upward from the tab 131 on both sides.

[0224] The length direction of the first inclined portion 412 may be arranged at an angle to the side direction of the tab 131. A plurality of first inclined portions 412 may be provided and arranged at positions spaced apart from each other. In this way, the plurality of first inclined portions 412 can form the bottom surface of the rack 400 on which cups or the like are placed.

[0225] Since the first inclined portions 412 are inclined, the cups placed on the first inclined portions 412 can be placed on the rack 400 generally at an angle to the up-down direction of the tubs 131 .

[0226] The first bent portion 413 may be bent from the first inclined portion 412 and coupled to the edge portion 411. Since the first inclined portion 412 has a structure having an incline, the first bent portion 413 may be formed at one end of the first inclined portion 412.

[0227] A plurality of first bent portions 413 may be provided, and each of the first bent portions 413 may be arranged to be spaced apart from each other. Each of the first bent portions 413 may extend from each of the first inclined portions 412.

[0228] The rack 400 may include a first flow path guide portion 440. The first flow path guide portion 440 may be coupled to the bottom portion 410 and arranged to direct the cleaning water inlet 1315 so that the water flowing in from the cleaning water inlet 1315 is directed toward the detergent flowing in the detergent inlet 1312.

[0229] The first flow path guide portion 440 may be disposed at a rear portion of the tub 131, adjacent to the cleaning water inlet 1315. Thus, the water that flows into the cleaning water inlet 1315 and pours into the inside of the tub 131 may change its flow path as it collides with the first flow path guide portion 440.

[0230] The first flow path guide portion 440 may include a base portion 441 and a first pad 442. The base portion 441 may be coupled to the bottom portion 410. The base portion 441 may be formed to protrude rearward from the bottom portion 410, and may be formed by bending a wire as a whole.

[0231] The first pad 442 is coupled to the base portion 441 and disposed at a position corresponding to the cleaning water inlet 1315, and is capable of changing the flow direction of the water flowing into the tub 131. The first pad 442 is formed in a curved shape when viewed in cross section, and is capable of guiding the water to flow in a downward direction of the tub 131.

[0232] The first pad 442 may be positioned to face directly toward the wash water inlet 1315. Thus, water entering the wash water inlet 1315 may be sprayed toward the first pad 442, where it may impact the first pad 442 and change direction of flow toward the underside of the tub 131.

[0233] First pad 442 may have a cross section formed by a curve, and first pad 442 may have a curved surface extending from the lower end toward cleaning water inlet 1315. Therefore, water that hits first pad 442 can approach the wall surface of tub 131 while flowing downward due to gravity.

[0234] On the other hand, the detergent inlet 1312 may be disposed below the wash water inlet 1315. The detergent that flows into the detergent inlet 1312 may flow down along the wall surface of the tub 131 because it has a relatively high viscosity.

[0235] The water that hits first pad 442 approaches the wall surface of tub 131 while flowing downward, and therefore meets with the detergent flowing down along the wall surface of tub 131. Therefore, the water flowing inside tub 131 meets with the detergent.

[0236] With this structure, the water flowing before entering the sump 133 mixes with the liquid detergent, so that the water can mix with the detergent more smoothly than if the detergent were to mix with the water stored in the sump 133.

[0237] During the washing process, the control unit provided in the cup washer can control the operation of the detergent pump 1301 so that detergent flows into the tub 131 when water flows into the tub 131 through the washing water inlet 1315. As a result, the flowing water and detergent mix with each other, so that the water can be smoothly mixed with the detergent.

[0238] In the embodiment, the rack 400 may include a first flow path guide unit 440 for guiding the flow direction of water at a position adjacent to the washing water inlet 1315 of the tub 131. Thus, the water flowing into the tub 131 may flow toward the detergent flowing into the tub 131 by the first flow path guide unit 440. As a result, the flowing water mixes with the detergent, and the water and the detergent may be smoothly mixed with each other, thereby improving the washing efficiency of the cup washer.

[0239] Although the present invention has been described above with reference to the illustrative drawings, the present invention is not limited to the embodiments and drawings disclosed in this specification, and it is clear that various modifications can be made by those skilled in the art within the scope of the technical concept of the present invention. Furthermore, even if the effects of the configuration of the present invention are not explicitly described and explained while describing the embodiments of the present invention, it is natural that the effects that can be predicted by the configuration should also be recognized.
