[0003] Recently, in order to prevent environmental pollution, in stores selling beverages, the provision of disposable cups to customers is being reduced. Customers visiting the store carry reusable cups such as thermos cups, and the trend of filling beverages in reusable cups is increasing.

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

[0005] Therefore, it is possible to provide convenience for users to wash their own cups by configuring a cup washer in the store that can wash cups carried by users. Such a cup washer needs to have a structure that can be easily used by anyone.

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

[0007] The cleaning process can generally be divided into a cleaning operation of spraying water onto the cup to wash the cup and a rinsing operation of spraying clean water onto the cup after washing with water to rinse the cup.

[0008] For thorough cleaning, it is necessary to mix detergent in the water for the cleaning operation and mix a rinsing agent in the water for the rinsing operation.

[0009] However, only the content of washing cups using steam is disclosed in the prior art. In particular, the content of washing cups without using detergent is disclosed in the prior art. Therefore, a cup washing method using detergent cannot be completely deduced from the prior art.

[0010] In order to thoroughly wash the cup when using a cup washer to wash the cup, it is necessary to inject detergent and a rinsing agent into the cleaning unit. Therefore, it is necessary to provide a device in the cup washer for injecting detergent and a rinsing agent into the cleaning unit.

[0011] In addition, in order to provide convenience to users, it is necessary to configure the detergent injection device and the rinsing agent injection device to inject detergent and a rinsing agent into the cleaning unit at an appropriate timing during the cleaning process without manual operation by the user.

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

[0013] Therefore, it is necessary to configure the detergent injection device and the rinsing agent injection device so that the path for injecting the detergent into the cleaning section and the path for injecting the rinsing agent into the cleaning section are separated.

[0014] In addition, in order to perform cleaning and rinsing smoothly, a structure for effectively mixing the water flowing into the cleaning water with the detergent or the rinsing agent needs to be provided in the cup washer. Summary of the Utility Model

[0048] Utility Model Effects

[0049] In the cup cleaning machine of the present utility model, the detergent injection device and the rinsing agent injection device may be separately disposed outside the tub of the cleaning unit. Through the detergent injection device and the rinsing agent injection device, the water flowing into the interior of the tub may be mixed with the detergent or the rinsing agent.

[0050] Therefore, when cleaning the cup by spraying water, the cleaning water mixed with water and detergent is sprayed onto the cup, thereby improving the cleaning efficiency of the cup. In addition, when rinsing the cup after cleaning the cup, the cleaning water mixed with water and rinsing agent is sprayed onto the cup, thereby effectively rinsing the cup.

[0051] In addition, in the cup cleaning machine of the present utility model, the detergent pump and the rinsing agent pump are connected to the control unit provided in the cup cleaning machine and operate at the time point set by the control unit to inject detergent or rinsing agent into the bucket, so that they can be mixed with water in the bucket. The management personnel can regularly supplement the detergent and the rinsing agent to the detergent storage unit and the rinsing agent storage unit.

[0052] Therefore, users who want to clean their own cups can conveniently use the detergent to improve the cleaning efficiency of the cup without additional operations for adding the detergent and the rinsing agent to water, and after cleaning the cup, use the rinsing agent to cleanly rinse the cup.

[0053] In addition, in the cup cleaning machine of the present utility model, the rinsing agent can flow into the bucket through the second connecting pipe, the three-way connecting part, the first connecting pipe and the cleaning water inlet. On the other hand, the detergent can flow in through the detergent inlet connected by an additional pipe. In addition, the time points when the detergent and the rinsing agent flow into the bucket can be different from each other.

[0054] Due to this structure, the paths for injecting the detergent and the rinsing agent into the bucket are separated, preventing the detergent and the rinsing agent from mixing with each other, thereby improving the efficiency of the cleaning operation and the rinsing operation of the cup cleaning machine.

[0055] In addition, in the cup cleaning machine of the present utility model, water and the rinsing agent can converge and flow in one pipe and flow into the bucket through the detergent inlet. Thus, water and the rinsing agent can be more evenly mixed while flowing, and the cleaning water in which water and the rinsing agent are evenly mixed is sprayed onto the cup, thereby effectively performing the rinsing operation of the cup.

[0056] In addition, in the cup cleaning machine of the present utility model, the bracket can be provided with a first flow path guiding part for guiding the flow direction of water at a position adjacent to the cleaning water inlet of the bucket. Thus, the water flowing into the bucket can be guided by the first flow path guiding part to flow toward the detergent flowing into the bucket. Therefore, the flowing water is mixed with the detergent, so that water and the detergent are smoothly mixed with each other, and the cleaning efficiency of the cup cleaning machine can be improved.

[0057] In addition to the above effects, the specific effects of the present utility model will be described together while explaining the specific content for implementing the following utility model. Description of the Drawings

These terms are only used to distinguish one component from another. Unless otherwise clearly stated, the first component may of course also be the second component.

[0082] Throughout the specification, unless otherwise clearly stated, each component may be singular or plural.

[0083] Unless otherwise clearly stated, the singular expressions used in this specification include plural expressions. In this application, terms such as "comprise" or "include" should not be construed as necessarily including all of the various components or various steps described in the specification, but should be construed as also being able to exclude some of the components or some of the steps, or further include additional components or steps.

[0084] Throughout the specification, unless otherwise clearly stated, "A and / or B" means A, B, or A and B, and unless otherwise clearly stated, "C to D" means C or more and D or less.

[0085] Throughout the specification, the "vertical direction" refers to the vertical direction of the cup washer in a state set for daily use. The "left - right direction" refers to the direction orthogonal to the vertical direction, and the front - back direction refers to the direction orthogonal to both the vertical direction and the left - right direction. The "both - side direction" or "side direction" has the meaning including the left - right direction and the front - back direction.

[0086] Figure 1 is a perspective view showing a cup washer according to an embodiment. Figure 2 is a view observed from another direction Figure 1 of it.

[0087] The cup washer of the embodiment can be installed, for example, in a store providing beverage services. The user of the cup washer can be a customer who purchases and drinks beverages. For environmental protection, recently, the provision of disposable cups to customers has been restricted in service stores, and this restricted range is gradually expanding.

[0088] Therefore, a cup washer can be installed in a service store so that users who carry reusable cups can wash and use the cups in the service store. The cups to be washed can be reusable cups such as thermos cups carried by users. Therefore, the cup washer can have a structure that is convenient for users to use.

[0089] At the upper part of the cup washer, a washing unit 130 for accommodating and washing cups can be provided. The washing unit 130 can be opened and closed by a door 150. At this time, the door 150 rotates on a hinge in the vertical direction of the cup washer, so that the washing unit 130 can be opened and closed.

[0090] Due to this structure, the user can open the door 150 by hand, place the cup into the washing unit 130, close the door 150 again, and then operate the cup washer to conveniently wash the cup without bending down.

[0091] It is necessary to appropriately adjust the height of the washing unit 130 of the cup washer to match the body of an adult so that the user can use the cup washer without bending down. In addition, in order to improve space efficiency, the cup washer needs to have a relatively small volume.

[0092] For this reason, the cup washer can have a tower - like shape with a relatively small cross - sectional area in the plane and a relatively long length in the vertical direction. Due to the tower - like shape, it is necessary to arrange the relatively large - volume components in the cup washer in the vertical direction.

[0093] In addition, due to the tower - like shape, there is a risk that the cup washer may tip over. To prevent the cup washer from tipping over, it is necessary to arrange components with a larger load at the lower part to lower the overall center of gravity.

[0094] Hereinafter, with reference to the accompanying drawings, the structure of the cup washer will be described in more detail. Figure 3 This is a view showing the state in which the door 150 of the cup washer according to an embodiment is open. Figure 4 This is a perspective view of the cup washer with some components omitted. Figure 5 This is Figure 4 a side view of

[0095] A cup washer according to an embodiment may include a base plate 110, a water storage tank 120, a cleaning unit 130, an intermediate plate 140, a door 150, and a frame 160.

[0096] The base plate 110 is disposed at the lowermost part of the cup washer and can support other components of the cup washer. The lower part of the base plate 110 can be placed on the ground. The base plate 110 may include a first part 111 and a second part 112. The bottom surface of the first part 111 can be placed on the ground and can support the second part 112.

[0097] The second part 112 can be disposed above the first part 111, and the water storage tank 120 can be disposed in the second part 112. The frame 160 can be coupled to the second part 112. For example, a front support member 161, a rear support member 162, and an intermediate support member 163 can be coupled to the second part 112. Therefore, the frame 160 can be supported by the second part 112.

[0098] The water storage tank 120 is disposed above the base plate 110 and can store water for cleaning the cups. The water storage tank 120 can be connected to a city water pipe using a pipe. Therefore, the water from the city water pipe can flow into and be stored in the water storage tank 120. In addition, the water storage tank 120 can be connected to the cleaning unit 130 using a pipe. Therefore, the water in the water storage tank 120 flows into the cleaning unit 130 and can be used to clean the cups accommodated in the cleaning unit 130.

[0099] A heating device can be provided inside the water storage tank 120. The water in the water storage tank 120 can be heated by the heating device and flow into the cleaning unit 130. Thus, the cups can be cleaned by using heated hot water, thereby improving the cleaning efficiency of the cups.

[0100] The water storage tank 120 can be filled with water. Therefore, compared with other components, the water storage tank 120 filled with water can have a relatively large load. The water storage tank 120 can be placed on the base plate 110 and disposed at the lower part of the cup washer.

[0101] Due to the load of the water-filled water storage tank 120 placed at the lower part of the cup washing machine, the height of the overall center of gravity of the cup washing machine can be reduced. Thus, the cup washing machine configured in a tower shape with a relatively long length in the vertical direction can maintain a stable state and is not easily overturned under external impacts.

[0102] The cleaning unit 130 is disposed above the water storage tank 120 and can clean the accommodated cups. A space for accommodating the cups can be formed in the cleaning unit 130. The cleaning unit 130 can be connected to the water storage tank 120 by a pipe. Thus, the water for cleaning can flow from the water storage tank 120 into the cleaning unit 130.

[0103] As another embodiment, the cleaning unit 130 can also be directly connected to the tap water pipe without passing through the water storage tank 120. Thus, according to the user's choice, the water flowing from the water storage tank 120 can be used to clean the cups, or the water flowing directly from the tap water pipe can be used to clean the cups.

[0104] The intermediate plate 140 is disposed between the water storage tank 120 and the cleaning unit 130 and can support the cleaning unit 130. The cleaning unit 130 is disposed above the intermediate plate 140, and the intermediate plate 140 can support a part of the load of the cleaning unit 130. The intermediate plate 140 has a substantially plate shape and is combined with a frame 160 at the edge, so that it can be supported by the frame 160.

[0105] The door 150 is disposed above the cleaning unit 130 and is hingedly rotated in the vertical direction, so that the open upper part of the cleaning unit 130 can be opened and closed. Refer to Figure 3 , the door 150 can be hingedly rotated in the vertical direction of the cup washing machine. Thus, the user can manually open the door 150 to put the cup 10 into the interior of the cleaning unit 130, and then close the door 150 again to clean the cup 10.

[0106] A top cover 210 can be provided at the upper end of the cleaning unit 130. A part of the top cover 210 can be combined with the upper end edge portion of the cleaning unit 130, and the door 150 is placed above it.

[0107] An inlet cover 213 can be provided at another part of the top cover 210. The inlet cover 213 can open and close the inlets for the detergent and the rinse agent introduced into the cleaning unit 130 and can be detachably provided on the top cover 210.

[0108] The user can put the cup into the cleaning unit 130 or take the cup out of the cleaning unit 130 by opening and closing the door 150 located at the upper end of the dishwasher. At this time, since the door 150 is hingedly rotated in the vertical direction, the user can conveniently move the door 150 without bending down.

[0109] In addition, since the door 150 rotates on its hinge, it can be arranged such that when the door 150 is open, the area occupied by the cup washer remains unchanged when viewed in a plane. Thus, regardless of whether the door 150 is open or closed, the planar cross-sectional area of the cup washer is constant, and thus no additional space is required to open the door 150.

[0110] In an embodiment, the cup is arranged to be hinge-rotatable in the up-and-down direction of the cup washer at the upper end of the cleaning unit 130, so that the user can open and close the door 150 without bending down, and thus the cup washer can be conveniently used. In addition, due to this structure, no additional space is required to open the door 150, and thus the space efficiency can be improved.

[0111] The frame 160 can be supported by the base plate 110 and is combined with the intermediate plate 140, and can support the cleaning unit 130. The frame 160 provides the internal space of the cup washer, where various components can be combined and these components can be supported.

[0112] The frame 160 can include a front support member 161, a rear support member 162, an intermediate support member 163, and an upper support member 164. Each component of the frame 160 can support the loads of the cleaning unit 130, the door 150, etc. provided at the upper part of the cup washer.

[0113] A pair of front support members 161 can be arranged at intervals from each other in front of the cup washer, with the lower part combined with the base plate 110, and the length direction is arranged in the up-and-down direction. The pair of front support members 161 can be arranged at positions spaced apart from each other in the side direction of the cup washer in front of the cup washer, forming the corner parts in front of the cup washer.

[0114] In order to form the corner parts of the cup washer, the cross-section of the front support member 161 can be formed in an L shape. The front support member 161 can be combined with the base plate 110 by a coupling mechanism such as a screw.

[0115] A pair of rear support members 162 can be arranged at intervals from each other behind the cup washer, with the lower part combined with the base plate 110, and the length direction is arranged in the up-and-down direction. The pair of rear support members 162 can be arranged at positions spaced apart from each other in the side direction of the cup washer behind the cup washer, and are arranged adjacent to the corner parts at the rear of the cup washer. The rear support member 162 can be combined with the base plate 110 by a coupling mechanism.

[0116] A pair of intermediate support members 163 can be arranged at intervals from each other, arranged between the front support member 161 and the rear support member 162, with the lower part combined with the base plate 110, and the length direction is arranged in the up-and-down direction. The pair of intermediate support members 163 can be arranged at positions spaced apart from each other in the side direction of the cup washer at the central part of the cup washer.

[0117] The intermediate support member 163 can be coupled to the base plate 110 by a coupling mechanism. Additionally, the intermediate support member 163 can be coupled to the intermediate plate 140 and the upper support member 164 by a coupling mechanism, so that the position can be stably maintained and the load of the cup washer components can be supported.

[0118] The upper support members 164 can be disposed above the intermediate support member 163, and a pair can be disposed spaced apart from each other in the lateral direction, with the longitudinal direction disposed in the front-rear direction, and the cleaning unit 130 is coupled thereto. The pair of upper support members 164 can be disposed at positions spaced apart from each other in the lateral direction of the cup washer at the upper part of the cup washer.

[0119] The cleaning unit 130 can be coupled to the upper support member 164 by a coupling mechanism. Therefore, the upper support member 164 can support the load of the cleaning unit 130.

[0120] A plurality of upper support members 164 can be provided spaced apart from each other in the vertical direction of the cup washer. Therefore, Figure 5 An embodiment is shown in which a pair is provided on both sides of the cup washer and a pair is provided in the vertical direction of the cup washer, so that a total of four are provided. However, the number of the upper support members 164 is not limited thereto.

[0121] Each upper support member 164 can be coupled to the front support member 161, the rear support member 162, and the intermediate support member 163. Therefore, the load of the cleaning unit 130 can be transmitted to the front support member 161, the rear support member 162, and the intermediate support member 163 through the upper support member 164, and finally transmitted to the base plate 110.

[0122] With this structure, the cup washer can stably support the cleaning unit 130 provided inside. The upper support member 164 can be coupled to the front support member 161, the rear support member 162, and the intermediate support member 163 by a coupling mechanism such as a screw.

[0123] In the embodiment, the components including the cleaning unit 130 provided at the upper part of the cup washer are supported by the frame 160, and each component can finally be supported by the base plate 110. Due to this structure, even in a state where a relatively heavy component such as the cleaning unit 130 is provided at the upper part of the cup washer, each component can be stably supported by the frame 160 and the base plate 110.

[0124] The cup washer can include a front panel 170 and a rear panel 180. The front panel 170 can be disposed in front of the cup washer so as to cover the water storage tank 120 and the cleaning unit 130. The front panel 170 can be coupled to the rear support member 162 of the frame 160 by a coupling mechanism.

[0125] The rear panel 180 can be coupled to the frame 160 to cover the rear of the cup washer. A first vent 181 can be provided in the rear panel 180 to ventilate the interior and exterior of the cup washer. The air flowing into the drying module 132 described below can flow into the interior of the cup washer through the first vent 181.

[0126] A handle 260 by which a user or a manager can hold the cup washer can be coupled to the rear panel 180 to facilitate the use of the cup washer.

[0127] The cup washer may include a display unit 190 which is coupled to the upper part of the rear support member 162 and is 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.

[0128] Accordingly, a user can observe the display unit 190 from the front part of the cup washer. Various information regarding the use of the cup washer can be displayed in the display unit 190 in the form of an image, text, or video.

[0129] A user can operate the cup washer or understand the operating state of the cup washer by observing the information displayed in the display unit 190. In addition, a command input device input in, for example, an electrostatic touch manner can be provided in the display unit 190. Accordingly, a user can use the display unit 190 to control the operation of the cup washer.

[0130] The cup washer may include a first circuit board unit 220 and a board unit support member 230. The first circuit board unit 220 may be disposed on one side of the water storage tank 120 and have a control unit for controlling the operation of the cup washer. Since a relatively small water storage path is configured compared to the cleaning unit 130, the first circuit board unit 220 can be disposed on one side of the water storage tank 120 in the lower part of the cup washer where a free space is generated.

[0131] The lower part of the board unit support member 230 may be coupled to the base plate 110, the upper part may be coupled to the intermediate plate 140, and the first circuit board unit 220 may be coupled thereto. The board unit support member 230 can be stably coupled to the base plate 110 by a coupling mechanism.

[0132] The board unit support member 230 can be used not only for fixing the first circuit board unit 220 but also for fixing the pipes disposed in the lower part of the cup washer.

[0133] The cup washer may include an exterior unit 250 which is coupled to the rear panel 180 and covers the rear support member 162. For coupling with other components of the cup washer, a plurality of fastening mechanisms can be coupled to the rear support member 162.

[0134] Therefore, in the case of a structure in which the rear support member 162 to which the fastening mechanism is fastened is directly exposed to the outside, the visual aesthetics of the cup washer may be degraded. Accordingly, a structure for covering the rear support member 162 to which the fastening mechanism is fastened is required.

[0135] The exterior portion 250 may cover the rear support member 162, and a relatively very small number of fastening mechanisms may be coupled compared to the rear support member 162. Due to this structure, the exterior portion 250 is disposed outside the cup washer at a position corresponding to the rear support member 162, so that the overall appearance of the cup washer may look neat.

[0136] Hereinafter, with reference to the drawings, the specific structure of the cleaning unit 130 will be described in detail. Figure 6 FIG. is a perspective view showing a cleaning unit 130 according to an embodiment. Figure 7 FIG. is a front view showing a cleaning unit 130 according to an embodiment.

[0137] Figure 8 FIG. is a side view showing a cleaning unit 130 according to an embodiment. Figure 9 FIG. is a rear view showing a 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.

[0138] The tub 131 may provide a space for accommodating a cup and spray cleaning water. A holder for placing the cup may be provided inside the tub 131, and a spraying device for spraying water may be provided at the lower portion. The open upper end of the tub 131 may be opened and closed by a door 150.

[0139] The drying module 132 may be configured to be connected to the tub 131 on one side of the tub 131 and spray heated air for drying into the tub 131. After the cup 10 is cleaned with water, water stains remain on the surface of the cup. The drying module 132 may dry the cup by blowing hot air, that is, heated air, onto the cup to blow dry the water remaining on the cup.

[0140] A heating device for heating the air flowing into the drying module 132 may be provided in the drying module 132. In addition, a blowing fan 1321 for forcibly flowing the air through a flow path formed in the drying module 132 may be provided in the drying module 132.

[0141] The sump 133 may be configured to be connected to the tub 131 below the tub 131 and store the water sprayed from the tub 131. The water stored in the sump 133 is circulated between the tub 131 and the sump 133 by the circulation pump 134 and sprayed from the tub 131 by the spraying device, thereby cleaning the cup 10 accommodated in the tub 131.

[0142] The circulation pump 134 can be configured to be connected to the lower side of the tub 131 and the tub 131 and the water collecting tank 133, so that water circulates between the tub 131 and the water collecting tank 133. The circulation pump 134 can force water to flow from the water collecting tank 133 to the tub 131.

[0143] The circulation pump 134 can be connected to a spraying device disposed at the lower part of the tub 131. Therefore, if the circulation pump 134 operates, the water stored in the water collecting tank 133 can flow into the spraying device and be sprayed into the interior of the tub 131 by the spraying device, thereby enabling the cups to be cleaned.

[0144] The drain pump 135 can be configured to be connected to the water collecting tank 133 at the lower side of the tub 131, so that water is discharged from the water collecting tank 133 to the outside. If the cups are cleaned with water, the drain pump 135 operates, so that the water stored in the water collecting tank 133 can be discharged to the outside of the cup washer through the discharge pipe connected to the drain pump 135.

[0145] The process of cleaning the cups 10 with the water stored in the water storage tank 120 is as follows. Water can flow into the water storage tank 120 from the water supply pipe through the pipe and be stored. The water in the water storage tank 120 can be heated by a heating device provided in the water storage tank 120. The heated hot water in the water storage tank 120 can flow into the interior of the tub 131 through the pipe and be stored in the water collecting tank 133 disposed at the lower part of the tub 131.

[0146] If the circulation pump 134 operates for cleaning the cups, the hot water can be sprayed from the water collecting tank 133 through the spraying device into the interior of the tub 131 and clean the cups. The hot water sprayed into the tub 131 can flow back into the water collecting tank 133 again, flow into the spraying device again by the circulation pump 134, and be sprayed into the interior of the tub 131 by the spraying device.

[0147] During the operation of the circulation pump 134, the cleaning hot water can flow through the water collecting tank 133, the spraying device, and the tub 131 in sequence, and this flow can be repeated. If the cups are cleaned with hot water, the circulation pump 134 stops and the drain pump 135 operates, so that the water stored in the water collecting tank 133 can be discharged to the outside.

[0148] If the drainage is completed by the drain pump 135, the drying module 132 operates, thereby spraying hot air into the interior of the tub 131, and after the hot air spraying is carried out for a set time, the cup cleaning operation including the drying process can be completed.

[0149] The cup washer can perform cleaning with a detergent and rinsing with a rinsing agent together. Hereinafter, the structure provided for injecting the detergent and the rinsing agent into the tub will be specifically described.

[0150] On the other hand, during the process of washing the cup with hot water, the washing process using the detergent and the rinsing process using the rinsing agent can be separated from each other. After the process of washing the cup by mixing the detergent in hot water is completed, the water in the water collecting tank 133 contains the detergent and foreign matters. Therefore, this contaminated water can be discharged to the outside by operating the drain pump 135.

[0151] After discharging the contaminated water to the outside, hot water is made to flow into the water collecting tank 133 again, the rinsing agent can be mixed in the hot water, and the rinsing operation can be performed by operating the circulation pump 134. In this way, the cleaning efficiency of the cup washer can be improved by separating the washing process using the detergent and the rinsing process using the rinsing agent.

[0152] The cleaning unit 130 may include a detergent storage unit 136, a rinsing agent storage unit 137, a detergent injection unit 138, a rinsing agent injection unit 139, a detergent pump 1301, and a rinsing agent pump 1302.

[0153] The detergent storage unit 136 may be arranged behind the tub 131 to store the detergent. The rinsing agent storage unit 137 may be separately arranged behind the tub 131 and separated from the detergent storage unit 136 to store the rinsing agent. Therefore, the detergent and the rinsing agent can be prevented from mixing with each other.

[0154] A detergent inlet 211 for putting in the detergent and a rinsing agent inlet 212 for putting in the rinsing agent may be provided on the top cover 210. The detergent inlet 211 may be connected to the detergent storage unit 136, and the rinsing agent inlet 212 may be connected to the rinsing agent storage unit 137. Therefore, the detergent flowing into the detergent inlet 211 can be stored in the detergent storage unit 136, and the rinsing agent flowing into the rinsing agent inlet 212 can be stored in the rinsing agent storage unit 137.

[0155] The detergent injection unit 138 may be connected to the detergent storage unit 136 and the tub 131, and can inject the detergent into the tub 131. The inlet of the detergent injection unit 138 may be connected to the detergent storage unit 136, and the outlet may be connected to the tub 131.

[0156] The rinsing agent injection unit 139 may be connected to the rinsing agent storage unit 137 and the tub 131, and can inject the rinsing agent into the tub 131. The inlet of the rinsing agent injection unit 139 may be connected to the rinsing agent storage unit 137, and the outlet may be connected to the tub 131.

[0157] The detergent pump 1301 is connected to the detergent injection unit 138 and can pump the detergent to the tub 131. The rinsing agent pump 1302 is connected to the rinsing agent injection unit 139 and can pump the rinsing agent to the tub 131. The operations of the detergent pump 1301 and the rinsing agent pump 1302 can be controlled by the control unit.

[0158] During the cleaning process, the control unit can mix the detergent and water by operating the detergent pump 1301, and during the rinsing process, it can mix the rinsing agent and water by operating the rinsing agent pump 1302.

[0159] The water storage tank 120 can be connected to the bucket 131 through pipes, so that the water in the water storage tank 120 can flow into the bucket 131. Therefore, after the water in the water storage tank 120 is heated to hot water, it flows into the bucket 131 and can be stored in the water collection tank 133 before the circulation pump 134 operates.

[0160] On the other hand, as mentioned above, the bucket 131 can be provided with a water supply path directly connected to the tap water pipe. Therefore, according to the user's choice, the cup can be generally cleaned or quickly cleaned.

[0161] General cleaning uses the hot water heated in the water storage tank 120 to clean the cup, and can use detergent and rinsing agent to clean the cup cleanly, but it takes a relatively long time.

[0162] Quick cleaning uses the raw water at room temperature supplied from the tap water pipe to clean the cup without using detergent and rinsing agent. Therefore, the cleaning time is relatively short, so that users who want to quickly clean cups with less pollution can use it conveniently.

[0163] Figure 10 It is a diagram showing a detergent injection device and a rinsing agent injection device according to an embodiment. Figure 11 It is a bottom view of the detergent injection device and the rinsing agent injection device. The cup washing machine can include a washing unit 130 for washing the accommodated cup 10. The washing unit 130 can include a bucket 131 that provides a space for accommodating the cup 10 and sprays washing water.

[0164] The washing unit 130 can include a detergent injection device for injecting detergent into the bucket 131 and an injection device for injecting a rinsing agent into the bucket 131. The detergent is mixed with water and sprayed onto the cup, so that the cup can be washed. The rinsing agent is mixed with water and sprayed onto the cup, so that the cup can be rinsed after washing the cup.

[0165] Therefore, after the detergent is used for washing the cup, the rinsing agent can be used for rinsing the cup. That is, the detergent and the rinsing agent can be mixed with the water sprayed into the bucket 131 at an interval time difference from each other. The detergent and the rinsing agent are in a liquid phase, so that they can be pumped by the detergent pump 1301 and flow into the interior of the bucket 131. The detergent injection device and the rinsing agent injection device can be arranged outside the bucket 131.

[0166] 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 may be disposed on one side of the tub 131 to store detergent. The management staff can regularly inject detergent into the detergent storage unit 136, so that the detergent can be stored in the detergent storage unit 136.

[0167] The detergent injection unit 138 may be coupled to the lower part of the detergent storage unit 136 to enable the detergent in the detergent storage unit 136 to be injected into the detergent pump 1301. Since the detergent injection unit 138 is disposed at the lower part of the detergent storage unit 136, the detergent can be concentrated by gravity into the detergent injection unit 138 and injected into the detergent pump 1301.

[0168] The detergent pump 1301 may be connected to the detergent injection unit 138 to pump the detergent to the tub 131. The operation of the detergent pump 1301 may be controlled by a control unit provided in the dishwasher. The detergent pump 1301 operates at a set time point, so that the detergent flowing in from the detergent injection unit 138 can be pumped to the tub 131.

[0169] The detergent pump 1301 may include a first body 611, a first connector 612, and a detergent discharge unit 613. Inside the first body 611, a motor that provides the pumping force for discharging the detergent, a gear device that connects the motor and the discharge device of the detergent discharge unit 613, etc. may be provided.

[0170] The first connector 612 may be coupled to the first body 611 and connected to the detergent injection unit 138, and the detergent may flow from the detergent injection unit 138 into the first connector 612. The first connector 612 may connect the detergent injection unit 138 and the detergent discharge unit 613 to each other.

[0171] One side of the detergent discharge unit 613 is connected to the first connector 612, and the other side is connected to the tub 131, so that the detergent can be discharged into the interior of the tub 131. A pipe is connected to the other side of the detergent discharge unit 613, and the detergent discharged from the detergent discharge unit 613 can be injected into the interior of the tub 131 through the pipe.

[0172] The detergent discharge unit 613 may include a detergent pumping unit 6131 and a detergent injection nozzle 6132. The detergent pumping unit 6131 may be connected to the first connector 612 to pump the detergent flowing in from the first connector 612. The detergent pumping unit 6131 may receive driving force from a motor provided in the body and be driven thereby to generate a pumping force to pump the detergent flowing into the first connector 612 to the tub 131.

[0173] The detergent injection nozzle 6132 can be combined with the detergent pumping unit 6131 and connected to the tub 131. For example, the detergent injection nozzle 6132 can have a pipe connected to the tub 131 installed at one end. The detergent injection nozzle 6132 can inject detergent into the tub 131. The inner diameter of the detergent injection nozzle 6132 is formed to be smaller than the inner diameter of the detergent pumping unit 6131 and can be connected with a pipe.

[0174] Figure 12 It is a side view showing a part of the cleaning unit 130. Figure 13 Viewed from the opposite direction Figure 12 Side view.

[0175] The rinse agent injection device can include a rinse agent storage unit 137, a rinse agent injection unit 139, and a rinse agent pump 1302. Referring to Figure 10 And Figure 11 , the detergent injection device and the rinse agent injection device can have substantially similar outer shapes, and some components can be arranged symmetrically with each other in the horizontal and vertical directions.

[0176] * The rinse agent storage unit 137 can be separately arranged on one side of the tub 131 from the detergent storage unit 136 and store the rinse agent. The management staff can regularly inject the rinse agent into the rinse agent storage unit 137, so that the rinse agent can be stored in the rinse agent storage unit 137.

[0177] The rinse agent injection unit 139 is combined with the lower part of the rinse agent storage unit 137 and can inject the rinse agent in the rinse agent storage unit 137 into the rinse agent pump 1302. Since the rinse agent injection unit 139 is arranged at the lower part of the rinse agent storage unit 137, the rinse agent can be concentrated by gravity to the rinse agent injection unit 139 and injected into the rinse agent pump 1302.

[0178] The rinse agent pump 1302 can be connected to the rinse agent injection unit 139 and pump the rinse agent to the tub 131. The operation of the rinse agent pump 1302 can be controlled by the control unit provided in the dishwasher. The rinse agent pump 1302 operates at a set time point, so that the rinse agent flowing in from the rinse agent injection unit 139 can be pumped to the tub 131.

[0179] The rinse agent pump 1302 can include a second main body 621, a second connector 622, and a rinse agent discharge part 623. Inside the second main body 621, a motor that provides the pumping force for discharging the rinse agent, a gear device that connects the motor and the discharge device of the rinse agent discharge part 623, etc. can be provided.

[0180] The second connector 622 is coupled to the second body 621 and connected to the rinse agent injection unit 139. The rinse agent can flow from the rinse agent injection unit 139 into the second connector 622. The second connector 622 can connect the rinse agent injection unit 139 and the rinse agent discharge unit 623 to each other.

[0181] One side of the rinse agent discharge unit 623 is connected to the second connector 622, and the other side is connected to the tub 131, so that the rinse agent can be discharged into the interior of the tub 131. A pipe is connected to the other side of the rinse agent discharge unit 623, and the rinse agent discharged from the rinse agent discharge unit 623 can be injected into the interior of the tub 131 through the pipe.

[0182] The rinse agent discharge unit 623 may include a rinse agent pumping unit 6231 and a rinse agent injection nozzle 6232. The rinse agent pumping unit 6231 can be connected to the second connector 622 so as to pump the rinse agent flowing in from the second connector 622. The rinse agent pumping unit 6231 can receive driving force from a motor provided in the main body and be driven thereby to generate a pumping force to pump the rinse agent flowing into the second connector 622 into the tub 131.

[0183] The rinse agent injection nozzle 6232 can be coupled to the rinse agent pumping unit 6231 and connected to the tub 131. For example, the rinse agent injection nozzle 6232 can have a pipe connected to the tub 131 installed at one end portion. The rinse agent injection nozzle 6232 can inject the rinse agent into the tub 131. The inner diameter of the rinse agent injection nozzle 6232 is formed to be smaller than the inner diameter of the rinse agent pumping unit 6231, and a pipe can be connected thereto.

[0184] In an embodiment, the detergent injection device and the rinse agent injection device can be separately arranged outside the tub 131 of the cleaning unit 130. Due to the detergent injection device and the rinse agent injection device, the water flowing into the interior of the tub 131 can be mixed with the detergent or the rinse agent.

[0185] Therefore, when cleaning the cup by spraying water, the cleaning water in which water and detergent are mixed is sprayed onto the cup, thereby improving the cleaning efficiency of the cup. In addition, when rinsing the cup after cleaning the cup, the cleaning water in which water and rinse agent are mixed is sprayed onto the cup, thereby effectively rinsing the cup.

[0186] In an embodiment, the detergent pump 1301 and the rinse agent pump 1302 are connected to a control unit provided in the cup washer and operate at a time point set by the control unit, so that the detergent or the rinse agent can be injected into the tub 131 and mixed with water in the tub 131. The management staff can regularly replenish the detergent and the rinse agent into the detergent storage unit 136 and the rinse agent storage unit 137.

[0187] Therefore, users who want to clean their cups can conveniently use detergent to improve the cleaning efficiency of the cups without the need for additional operations to add detergent and rinsing agent to the water, and after cleaning the cups, use the rinsing agent to cleanly rinse the cups.

[0188] Figure 14 It is a perspective view showing the detergent injection part 138 of an embodiment. Figure 15 It is viewed from another direction Figure 14 of the figure. Figure 16 It is a view showing a part of the detergent injection device. Figure 17 It is a view showing a part of the cleaning part 130.

[0189] The detergent injection part 138 may include a first lower cover 1381 and a first connection part 1382. The first lower cover 1381 is coupled to the lower part of the detergent storage part 136 and can cover the open bottom surface of the detergent storage part 136. Since the first lower cover 1381 covers the bottom surface of the detergent storage part 136, the liquid-phase detergent stored in the detergent storage part 136 drops due to gravity and can be placed on the top surface of the first lower cover 1381.

[0190] The first connection part 1382 may protrude downward from the first lower cover 1381 and be coupled to the first connector 612, and a first flow hole 1382a for the detergent to flow is formed. The detergent placed on the top surface of the first lower cover 1381 can flow into the first connector 612 through the first flow hole 1382a provided in the first connection part 1382.

[0191] The first lower cover 1381 may be formed inclined such that the height of the top surface decreases as it gets closer to the first flow hole 1382a. Therefore, the liquid-phase detergent placed on the top surface of the first lower cover 1381 can flow along the top surface of the first lower cover 1381 due to gravity and concentrate at the entrance of the first flow hole 1382a, which is at the lowest position on the inclined top surface of the first lower cover 1381.

[0192] The detergent concentrated at the entrance of the first flow hole 1382a can descend through the first flow hole 1382a, flow into the detergent discharge part 613 through the first connector 612, and be pumped from the detergent pumping part 6131 and flow into the tub 131 through the detergent injection nozzle 6132 and the pipe.

[0193] Figure 18 It is a perspective view showing the rinsing agent injection part 139 of an embodiment. Figure 19 It is viewed from another direction Figure 18 of the figure. Figure 20 It is a view showing a part of the rinsing agent injection device.

[0194] The rinsing agent injection unit 139 may include a second lower cover 1391 and a second connection part 1392. The second lower cover 1391 may be coupled to the lower part of the rinsing agent storage unit 137 and may cover the open bottom surface of the rinsing agent storage unit 137. Since the second lower cover 1391 covers the bottom surface of the rinsing agent storage unit 137, the liquid-phase rinsing agent stored in the rinsing agent storage unit 137 may drop due to gravity and thus may be placed on the top surface of the second lower cover 1391.

[0195] The second connection part 1392 may protrude downward from the second lower cover 1391, be coupled to the second connector 622, and may have a second flow hole 1392a through which the rinsing agent flows. The rinsing agent placed on the top surface of the second lower cover 1391 may flow into the second connector 622 through the second flow hole 1392a provided in the second connection part 1392.

[0196] The second lower cover 1391 may be formed to be inclined such that the height of the top surface decreases as it gets closer to the second flow hole 1392a. Accordingly, the liquid-phase rinsing agent placed on the top surface of the second lower cover 1391 may flow along the top surface of the second lower cover 1391 due to gravity and may be concentrated at the entrance of the second flow hole 1392a, which is at the lowest position in the inclined top surface of the second lower cover 1391.

[0197] The rinsing agent concentrated at the entrance of the second flow hole 1392a may drop through the second flow hole 1392a, flow into the rinsing agent discharge part 623 through the second connector 622, be pumped by the rinsing agent pumping part 6231, and flow into the tub 131 through the rinsing agent injection nozzle 6232 and a pipe.

[0198] On the other hand, as Figure 9 shown, the tub 131 may include a detergent inlet 1312 and a cleaning water inlet 1315. The detergent inlet 1312 may be connected to the detergent injection nozzle 6132 using a pipe, and the detergent may flow into the tub 131 from the detergent injection nozzle 6132. The detergent discharged from the detergent discharge part 613 may flow into the inside of the tub 131 through the detergent inlet 1312.

[0199] The cleaning water inlet 1315 may be disposed above the detergent inlet 1312 so that water may flow into the tub 131. The cleaning water inlet 1315 may be connected to the water storage tank 120 using a pipe, and hot water may flow into the inside of the tub 131 from the water storage tank 120 through the cleaning water inlet 1315.

[0200] In addition, the rinsing agent may flow into the inside of the tub 131 through the cleaning water inlet 1315. A detailed description thereof will be given below. Figure 21 It is a view showing a structure in which pipes are connected to the cleaning unit 130.

[0201] The cup washer may include a water storage tank 120, a first connection pipe 631, a second connection pipe 632, and a tee connection part 633. The water storage tank 120 may be disposed below the cleaning part 130 to store water for cleaning cups.

[0202] The first connection pipe 631 may connect the cleaning water inlet 1315 and the water storage tank 120. The water in the water storage tank 120 may be heated by a heating device, and thus may flow into the tub 131 through the first connection pipe 631 and the cleaning water inlet 1315.

[0203] The second connection pipe 632 may connect the rinse agent injection nozzle 6232 and the first connection pipe 631. The tee connection part 633 may be installed on the first connection pipe 631, and one end of the second connection pipe 632 may be installed on the tee connection part 633. Therefore, the rinse agent discharged from the rinse agent injection nozzle 6232 may be mixed with the water flowing in the first connection pipe 631 at the tee connection part 633, and the water mixed with the rinse agent may flow into the interior of the tub 131 through the cleaning water inlet 1315.

[0204] Due to this structure, the rinse agent discharged from the rinse agent injection nozzle 6232 may flow into the first connection pipe 631 from the second connection pipe 632, and may be mixed with the water flowing in the first connection pipe 631 and flow into the interior of the tub 131.

[0205] In the case of performing a rinsing operation, first, the water mixed with the contaminants and detergent stored in the water collection tank 133 may be discharged to the outside of the cup washer by the drain pump 135. Then, hot water may flow into the tub 131 again from the water storage tank 120 through the cleaning water inlet 1315 and be stored in the water collection tank 133 at the lower part of the tub 131.

[0206] The water stored in the water collection tank 133 may be circulated between the tub 131 and the water collection tank 133 by the circulation pump 134, so that the cups accommodated inside the tub 131 may be rinsed by spraying water. In the case of performing such a rinsing operation, a rinse agent may be mixed in the water.

[0207] For the rinsing operation, when the water flows from the water storage tank 120 into the tub 131 and fills the water collection tank 133, the rinse agent may be pumped simultaneously at the time point when the water flows in the first connection pipe 631. At this time, since the second connection pipe 632 through which the rinse agent flows is connected to the first connection pipe 631 through the tee connection part 633, the rinse agent may be mixed with the water and flow into the interior of the tub 131.

[0208] Water and the rinsing agent are mixed and flow together at the three-way connection part 633. When they continue to flow and are stored in the water collecting tank 133, the water and the rinsing agent are further mixed, so that the water collecting tank 133 can be in a state where the water and the rinsing agent are evenly mixed.

[0209] On the other hand, after the cleaning operation using the detergent, the rinsing agent can be used for the rinsing operation to wash off the rinsing agent remaining on the surface of the cup. Therefore, it is necessary to separate the detergent and the rinsing agent from each other and not to mix them during the entire process of the cup cleaning operation.

[0210] Therefore, a detergent inlet 1312 separated from the cleaning water inlet 1315 can be formed in the bucket 131, and the detergent injection nozzle 6132 and the detergent inlet 1312 can be connected to the first connection pipe 631 or the second connection pipe 632 using other additional pipes.

[0211] In the embodiment, the rinsing agent can flow into the bucket 131 through the second connection pipe 632, the three-way connection part 633, the first connection pipe 631, and the cleaning water inlet 1315. On the other hand, the detergent can flow in through the detergent inlet 1312 connected by an additional pipe. In addition, the time points when the detergent and the rinsing agent flow into the bucket 131 can be different from each other.

[0212] Due to this structure, the paths for injecting the detergent and the rinsing agent into the bucket 131 are separated, preventing the detergent and the rinsing agent from mixing with each other, thereby improving the efficiency of the cleaning operation and the rinsing operation of the cup washer.

[0213] In the embodiment, water and the rinsing agent can converge and flow in one pipe and flow into the bucket 131 through the detergent inlet 1312. Thereby, water and the rinsing agent can be more evenly mixed while flowing, and the cleaning water in which water and the rinsing agent are evenly mixed is sprayed onto the cup, so that the rinsing operation of the cup can be effectively carried out.

[0214] As described above, the cup washer can include a drying module 132, a water collecting tank 133, a circulation pump 134, and a drainage pump 135. The drying module 132 is configured to be connected to the bucket 131 at the side part of the bucket 131 and can spray heated air into the interior of the bucket 131. After performing the foregoing cleaning operation and rinsing operation, the drying module 132 is operated, whereby the water remaining on the surface of the cup accommodated in the bucket 131 can be dried.

[0215] The water collecting tank 133 can be configured to be connected to the lower side of the bucket 131 and store the water sprayed from the bucket 131. The circulation pump 134 is configured to be connected to the bucket 131 and the water collecting tank 133 at the lower side of the bucket 131, and can circulate water between the bucket 131 and the water collecting tank 133. By operating the circulation pump 134 to circulate the water and spray it into the bucket 131, the cups accommodated in the bucket 131 can be cleaned or rinsed.

[0216] The drain pump 135 can be configured to be connected to the water collecting tank 133 at the lower side of the bucket 131 and discharge the water from the water collecting tank 133 to the outside. After the cleaning operation or rinsing operation is completed, the water stored in the water collecting tank 133 can be discharged to the outside of the cup washer through the drain pump 135.

[0217] As Figure 15 and Figure 16 shown, the detergent injection part 138 can include a first-1 lid coupling projection 1383, a first-2 lid coupling projection 1384, and a first-3 lid coupling projection 1385. The first-1 lid coupling projection 1383 can protrude from the first lower lid 1381 and be coupled to the bucket 131. At a position corresponding to the first-1 lid coupling projection 1383 in the bucket 131, a coupling projection protrudes, and the first-1 lid coupling projection 1383 and the coupling projection of the bucket 131 can be coupled to each other by a coupling mechanism such as a screw.

[0218] The first-2 lid coupling projection 1384 can protrude from the first lower lid 1381 and be coupled to the first connector 612. The first-3 lid coupling projection 1385 can protrude from the first lower lid 1381 and form a first insertion groove 1385a.

[0219] Correspondingly, the first connector 612 can include a first fastening part 6121 and a first coupling hook 6122. The first fastening part 6121 can protrude from the first connector 612 in a lateral direction to be fastened to the first-2 lid coupling projection 1384.

[0220] The first-2 lid coupling projection 1384 can include: a first large-diameter part 1384a having a relatively large outer diameter; and a first small-diameter part 1384b protruding from the first large-diameter part 1384a and having a relatively small outer diameter. Holes for fastening the coupling mechanism can be formed in the first large-diameter part 1384a and the first small-diameter part 1384b.

[0221] The first fastening portion 6121 of the first connector 612 may be formed with a hole, and the first small-diameter portion 1384b of the first cover coupling projection 1384 may be inserted into the hole of the first fastening portion 6121. In a state where the first small-diameter portion 1384b is inserted into the first fastening portion 6121, the first cover coupling projection 1384 and the first fastening portion 6121 may be coupled to each other by a coupling mechanism.

[0222] The first coupling hook 6122 may be inserted into the first insertion groove 1385a to be coupled to the first cover coupling projection 1385 of the 1-3rd cover. The first insertion groove 1385a may be formed to have a predetermined length in the vertical direction of the detergent injection portion 138. The first coupling hook 6122 may move in the length direction of the first insertion groove 1385a, that is, in the vertical direction of the detergent injection portion 138, and be inserted into the first insertion groove 1385a.

[0223] The first coupling hook 6122 may be formed such that it is not easily detached from the first insertion groove 1385a when moving downward in a state of being inserted into the first insertion groove 1385a. Therefore, the first cover coupling projection 1385 of the 1-3rd cover may be stably held in a state of being coupled to the first connector 612 without a fastening mechanism.

[0224] As Figure 17 shown, the detergent pump 1301 may be coupled to the drying module 132. For this purpose, a first module fastening portion 6111 may be provided on the first main body 611 of the detergent pump 1301, and a first module fastening portion 132a may be provided on the drying module 132.

[0225] The first module fastening portion 6111 may be formed to protrude toward the side direction of the first main body 611 and be fastened to the drying module 132. Correspondingly, the first module fastening portion 132a may protrude from the drying module 132 toward the first module fastening portion 6111, and the first module fastening portion 6111 may be fastened to the first module fastening portion 132a. The first module fastening portion 6111 and the first module fastening portion 6111 may be coupled to each other by a coupling mechanism.

[0226] Therefore, a part of the detergent injection device may be coupled to the tub 131, and another part may be coupled to the drying module 132. Due to this structure, the drying module 132 may be disposed between the tub 131 and the detergent injection device, and the drying module 132 and the detergent injection device may overlap at least a part of each other.

[0227] Accordingly, the space efficiency of the cup washer can be improved by reducing the space for arranging the drying module 132 and the detergent injection device. In addition, since the detergent injection device is coupled to 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.

[0228] As Figure 19 and Figure 20 shown, the rinse agent injection unit 139 may include a second-1 lid coupling protrusion 1393, a second-2 lid coupling protrusion 1394, and a second-3 lid coupling protrusion 1395. The second-1 lid coupling protrusion 1393 may protrude from the second lower lid 1391 and be coupled to the tub 131. At a position corresponding to the second-1 lid coupling protrusion 1393 in the tub 131, a coupling protrusion protrudes, and the second-1 lid coupling protrusion 1393 and the coupling protrusion of the tub 131 may be coupled to each other by a coupling mechanism such as a screw.

[0229] The second-2 lid coupling protrusion 1394 may protrude from the second lower lid 1391 and be coupled to the second connector 622. The second-3 lid coupling protrusion 1395 may protrude from the second lower lid 1391 and a second insertion groove 1395a is formed.

[0230] Correspondingly, the second connector 622 may include a second fastening portion 6221 and a second coupling hook 6222. The second fastening portion 6221 may protrude from the second connector 622 in a lateral direction to be fastened to the second-2 lid coupling protrusion 1394.

[0231] The second-2 lid 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. Holes for fastening by a coupling mechanism may be formed in the second large-diameter portion 1394a and the second small-diameter portion 1394b.

[0232] A hole may be formed in the second fastening portion 6221 of the second connector 622, and the second small-diameter portion 1394b of the second-2 lid coupling protrusion 1394 may be inserted into the hole of the second fastening portion 6221. In a state where the second small-diameter portion 1394b is inserted into the second fastening portion 6221, the second-2 lid coupling protrusion 1394 and the second fastening portion 6221 may be coupled to each other by a coupling mechanism.

[0233] The second coupling hook 6222 can be inserted into the second insertion groove 1395a to be coupled to the 2-3 lid coupling protrusion 1395. The second insertion groove 1395a can be formed to have a predetermined length in the vertical direction of the rinse agent injection unit 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 agent injection unit 139, and be inserted into the second insertion groove 1395a.

[0234] The second coupling hook 6222 can be formed such that it is not easily detached from the second insertion groove 1395a when moving downward in the state of being inserted into the second insertion groove 1395a. Therefore, the 2-3 lid coupling protrusion 1395 can be stably maintained in a state of being coupled to the second connector 622 without a fastening mechanism.

[0235] As Figure 17 shown, the rinse agent pump 1302 can be coupled to the drying module 132. For this purpose, a 2-1 module fastening part 6211 can be provided on the second main body 621 of the rinse agent pump 1302, and a 2-2 module fastening part 132b can be provided on the drying module 132.

[0236] The 2-1 module fastening part 62,11 can be formed to protrude toward the side direction of the second main body 621 and be fastened to the drying module 132. Correspondingly, the 2-2 module fastening part 132b can protrude from the drying module 132 toward the 2-1 module fastening part 6211, and the 2-1 module fastening part 6211 can be fastened to the 2-2 module fastening part 132b. The 2-1 module fastening part 6211 and the 2-1 module fastening part 6211 can be coupled to each other by a coupling mechanism.

[0237] Therefore, a part of the rinse agent injection device can be coupled to the tub 131. Another part can be coupled to the drying module 132. Due to this structure, the drying module 132 can be disposed between the tub 131 and the rinse agent injection device, and the drying module 132 and the rinse agent injection device can overlap at least a part of each other.

[0238] Thereby, the space efficiency of the cup washer can be improved by reducing the space for disposing the drying module 132 and the rinse agent injection device. In addition, by coupling the rinse agent injection device to the drying module 132 and the tub 131, the coupling between the rinse agent injection device, the drying module 132, and the tub 131 can be made firm.

[0239] Figure 22FIG. 0 is a side view of a part of a bracket 400 showing an embodiment. The cleaning water inlet 1315 is arranged at a position separated from the detergent inlet 1312 and may be arranged on the upper side of the detergent inlet 1312. Therefore, the water flowing into the cleaning water inlet 1315 does not converge with the detergent flowing into the tub 131. The water flows into the water collecting trough 133 located at the lower part of the tub 131. Similarly, after the detergent also flows into the water collecting trough 133, the detergent and the water can be mixed with each other.

[0240] When water is stored in the water collecting trough 133, the flow of the water is not very active. Therefore, when the water and the detergent are mixed in the water collecting trough 133, the water may not be well mixed with the detergent.

[0241] Therefore, in order to improve the mixing efficiency, it is necessary to mix the water and the detergent with each other near the respective inlets where the water and the detergent flow into the tub 131. The flow of the water is particularly active at the inlet of the tub 131. Therefore, when the mixing occurs near the respective inlets of the tub 131, the mixing of the detergent and the water can proceed smoothly. The following describes such a structure.

[0242] 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 the rear part of the tub 131. The detergent inlet 1312 may be formed to penetrate through one side of the tub 131 and may be a passage for the detergent to flow into the tub 131. The cleaning water inlet 1315 may be arranged on the upper side of the detergent inlet 1312 and may be a passage for the water to flow into the tub 131.

[0243] The cleaning section 130 may include a bracket 400. The bracket 400 may be arranged inside the tub 13 and is for placing cups and may be formed by binding a plurality of steel wires to each other. For example, cups, lids of cups, straws, etc. may be placed on the bracket 400.

[0244] At this time, the cup may be placed upside down on the bracket 400. That is, the open inlet of the cup is placed at the lower part of the bracket 400, and the bottom of the cup may be placed at the upper part of the bracket 400. Thus, the water sprayed upward from the lower side to the upper side of the bracket 400 can smoothly flow into the inside of the cup and clean the inside of the cup.

[0245] The entire bracket 400 may be formed by binding steel wires to each other to form a three-dimensional mesh structure. Due to this shape, cups and the like can be easily placed on the bracket 400, and the sprayed water can easily clean the cups and the like placed on the bracket 400 through the lower part of the bracket 400.

[0246] The bracket 400 may include a bottom 410. The bottom 410 is disposed at the bottom of the tub 131 and can support the cup placed on the bracket 400 from the lower side. In order to stably support the cup and the like, the bottom 410 may have a shape that spreads relatively wide in the front, back, left, and right directions along the side direction of the tub 131.

[0247] The bottom 410 may include an edge portion 411, a first inclined portion 412, and a first bent portion 413. The edge portion 411 forms the edge of the bottom 410 and may be formed such that a part of it protrudes upward from both sides toward the tub 131.

[0248] The first inclined portion 412 may be configured such that its longitudinal direction is inclined with respect to the side direction of the tub 131. There may be a plurality of first inclined portions 412, which are respectively disposed at positions spaced apart from each other. Thus, the plurality of first inclined portions 412 may form the bottom surface of the bracket 400 for placing the cup and the like.

[0249] Since the plurality of first inclined portions 412 are inclined, the cup placed on the first inclined portion 412 can be placed on the bracket 400 inclined as a whole with respect to the up and down direction of the tub 131.

[0250] The first bent portion 413 may be bent from the first inclined portion 412 and joined to the edge portion 411. In order to make the first inclined portion 412 have an inclined structure, the first bent portion 413 may be formed at one end of the first inclined portion 412.

[0251] There may be a plurality of first bent portions 413, and the respective first bent portions 413 are spaced apart from each other, and each first bent portion 413 may extend from its respective first inclined portion 412.

[0252] The bracket 400 may include a first flow path guiding portion 440. The first flow path guiding portion 440 is combined with the bottom 410 and faces the cleaning water inlet 1315, so that the water flowing in from the cleaning water inlet 1315 can be directed toward the detergent flowing into the detergent inlet 1312.

[0253] The first flow path guiding portion 440 may be disposed at the rear portion of the tub 131 and at a position adjacent to the cleaning water inlet 1315. Therefore, the water flowing into the cleaning water inlet 1315 and falling into the interior of the tub 131 can collide with the first flow path guiding portion 440, thereby changing the flow path.

[0254] The first flow path guiding portion 440 may include a base portion 441 and a first pad 442. The base portion 441 may be combined with the bottom 410. The base portion 441 may be formed to protrude rearward from the bottom 410 and is formed by bending a wire as a whole.

[0255] The first cushion 442 is coupled to the base portion 441 and is disposed at a position corresponding to the washing water inlet 1315, so that the flow direction of the water flowing into the tub 131 can be changed. The cross-section of the first cushion 442 is formed in a curved shape, so that the water can be guided to flow downward in the tub 131.

[0256] The first cushion 442 can be disposed to directly face the washing water inlet 1315. Therefore, the water flowing into the washing water inlet 1315 can be jetted toward the first cushion 442, and while colliding with the first cushion 442, the flow direction is changed toward the lower side of the tub 131.

[0257] The cross-section of the first cushion 442 can be formed in a curve, and the first cushion 442 can have a curved surface from the lower end portion toward the washing water inlet 1315. Therefore, the water colliding with the first cushion 442 can approach the wall surface of the tub 131 while flowing downward under the action of gravity.

[0258] On the other hand, the detergent inlet 1312 can be disposed below the washing water inlet 1315. Since the viscosity of the detergent flowing into the detergent inlet 1312 is high, it can flow down along the wall surface of the tub 131.

[0259] The water colliding with the first cushion 442 can approach the wall surface of the tub 131 while flowing downward, so that it can converge with the detergent flowing down along the wall surface of the tub 131. Therefore, the water flowing inside the tub 131 can converge with the detergent.

[0260] Due to this structure, the water flowing at a position before flowing into the water collecting tank 133 converges with the liquid-phase detergent. Therefore, compared with the case where the detergent is mixed in the water staying in the water collecting tank 133, the water can be smoothly mixed with the detergent.

[0261] During the cleaning process, the control unit provided in the cup washer can control the operation of the detergent pump 1301 so that the detergent flows into the tub 131 at the time when the water flows into the tub 131 through the washing water inlet 1315. Thus, the flowing water and the detergent are mixed with each other, so that the water can be smoothly mixed with the detergent.

[0262] In an embodiment, the bracket 400 can be provided with a first flow path guiding portion 440 for guiding the flow direction of the water at a position adjacent to the washing water inlet 1315 of the tub 131. Thus, the water flowing into the tub 131 can be guided by the first flow path guiding portion 440 to flow toward the detergent flowing into the tub 131. Therefore, the flowing water is mixed with the detergent, so that the water and the detergent are smoothly mixed with each other, and the cleaning efficiency of the cup washer can be improved.

[0263] As described above, the present utility model has been illustrated with reference to the exemplary drawings. However, the present utility model is not limited to the embodiments and drawings described in this specification. Obviously, those of ordinary skill in the art can make various changes within the scope of the technical idea of the present utility model. In addition, even if the functions and effects of the components of the present utility model are not explicitly described in the embodiments of the present utility model described above, the effects that can be predicted by the components should of course be recognized.
