Description

[Technical field]

[0001] The present disclosure relates to a multi-purpose cup washer, and more particularly to a multi-purpose cup washer capable of automatically washing cups, tumblers and accessories for multi-use cups, such as tumbler lids. [Background technology]

[0002] In order to protect the environment, there are growing calls to limit the use of disposable cups and use personal cups or tumblers.

[0003] In accordance with this atmosphere, beverage stores and the like may offer services such as points or discounts to customers who bring their own cups or tumblers and purchase beverages or coffee.

[0004] Customers may need to empty their personal cups or tumblers to refill or pour in new beverages. In this case, the cups or tumblers need to be washed. Customers have the inconvenience of having to ask the store staff to wash the cups or tumblers.

[0005] In addition to the inconvenience of always being unable to carry around a personal cup or tumbler, it is also difficult to wash them hygienically in a timely manner, which is why the use of personal cups or tumblers is currently low.

[0006] To address these issues, a multi-use cup sharing service has been put into operation.

[0007] The multi-use cup sharing service is a service in which multi-use cups with identifiers such as barcodes or QR codes (registered trademarks) are provided at beverage retailers, and a cup deposit is added to the payment for a beverage using the provided multi-use cup, and the deposit is returned when the multi-use cup is returned.

[0008] To promote this service, a method is needed to hygienically wash the cups shared by many people before use. Therefore, an automatic cup washer that automatically washes the cups would be the solution.

[0009] However, most conventional cup washers are designed to wash a large number of cups at once, and therefore take up a lot of space and are expensive.

[0010] In addition, conventional cup washers are limited to a cup washing function, making it difficult to properly wash accessories such as tumbler lids. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, preferred embodiments of the present disclosure will be described with reference to the accompanying drawings. The present disclosure will be described with reference to the embodiments shown in the drawings, which are merely examples, and the technical ideas and core configurations and operations of the present disclosure are not limited thereto.

[0021] FIG. 1 is a perspective view showing a multipurpose cup washer 1 (hereinafter simply referred to as "the washer") according to one embodiment.

[0022] 1, the washer 1 is formed in a thin and long shape so that it can be installed in a narrow space. The washer 1 is composed of an upper module 10 and a lower module 20.

[0023] The upper module 10 includes a side cover 130 that forms an internal space 131 in which an object to be washed, such as a cup, can be placed, a top cover 110 that covers the upper part of the side cover 130, and a door 120 that can open or close the internal space 131 formed by the side cover 130.

[0024] The side cover 130 and the door 120 may be made of a transparent material so that a user can check the cleaning process.

[0025] A touch screen 111 is formed on the top cover 110 to provide a user interface for allowing a user to input commands and check the cleaning status. A control device (not shown) and a communication device (not shown) are also built into the top cover 110. The control device processes input signals from the touch screen, sensors, etc., and outputs operation commands to components such as motors, valves, pumps, and lamps to control the operation of the washer 1.

[0026] According to the present embodiment, the touch screen 111 is fixed to the top cover 110, but the present invention is not limited thereto, and the washing machine 1 may have a wired or wireless communication function and may be linked to an external smart terminal such as a smartphone or tablet through wired or wireless communication. That is, a smart terminal linked to the washing machine 1 may be used as a user interface device.

[0027] FIG. 2 is a view showing the inside of the upper module 10. As shown in FIG.

[0028] An internal space 131 is defined by the side cover 130 and the top cover 110 of the upper module 10. The door 120 is connected to a motor 122 located at the bottom end of the top cover 110 through an extension bar 121 extending from the door 120 along approximately the bottom end surface of the top cover 110. As the rotation shaft of the motor 122 rotates, the extension bar 121 rotates around the rotation shaft, and the door 120 rotates sideways due to the rotation of the extension bar 121 to open or close the internal space 131. FIG. 1 shows a state in which the door 120 is closed, and FIG. 2 shows a state in which the door 120 is open.

[0029] The objects to be washed, such as cups, tumblers, and tumbler lids, are placed in the internal space 131 and washed.

[0030] As shown in FIG. 2, a sterilization / cleaning unit 200, a support unit 300, and a lifting unit 400 are formed in the internal space 131.

[0031] FIG. 3 shows the sterilization / cleaning unit 200 in greater detail.

[0032] As shown in Fig. 3, the sterilization / washing unit 200 is formed with a stand 201 on which a cup or tumbler is placed upside down (see Fig. 7). According to this embodiment, the washing operation process of the cup and the tumbler is substantially the same, so here, unless a cup and a tumbler are specifically distinguished, they are commonly referred to as a cup member 2. In this specification, a cup is commonly referred to as a liquid container to which no separate lid is attached, and a tumbler is commonly referred to as a liquid container intended to be sealed by attaching a separate lid.

[0033] A drain outlet may be formed in the mounting base 201, but in this embodiment, since drainage is not smooth, a sink 202 that is deeper than the mounting base 201 is formed next to the mounting base 201 in order to prevent the cleaning liquid from accumulating and contaminating the cup member 2. A drain outlet 203 is formed in the sink 202. The upper surface of the mounting base 201 may be slightly inclined toward the sink 202 so that the cleaning liquid flows toward the sink 202.

[0034] A first jet nozzle 210 is formed in the center of the mounting base 201 so as to protrude upward from the mounting base 201 .

[0035] The first injection nozzle 210 is formed in a substantially cylindrical shape. Nozzle holes 211 and 212 are formed on the top and side of the first injection nozzle 210. The nozzle holes 211 and 212 are slit-shaped with a predetermined length. Although not shown in detail in the drawings, a plurality of side nozzle holes 212 are formed on the side of the first injection nozzle 210 along the periphery of the side. The first injection nozzle 210 injects the cleaning liquid through the nozzle holes 211 and 212.

[0036] A first light germicidal lamp 240 is formed around the periphery of the first injection nozzle 210. The first light germicidal lamp 240 irradiates the inside of the cup member 2 placed upside down on the mounting base 201 with ultraviolet light to perform ultraviolet sterilization.

[0037] The mounting base 201 has a plurality of cup receiving protrusions 220 formed thereon, protruding from the upper surface of the mounting base 201 along the periphery of the first light germicidal lamp 240. The cup member 2 placed upside down on the mounting base 201 is placed on the cup receiving protrusions 220 and spaced apart from the upper surface of the mounting base 201. Even if the upper surface of the mounting base 201 is slightly inclined toward the sink 202, the upper surfaces of the plurality of cup receiving protrusions 220 are formed at the same height, preventing the cup member 2 from tilting.

[0038] The cup receiving protrusion 220 prevents the cleaning liquid sprayed into the inside of the cup member 2 through the first spray nozzle 210 from being trapped inside the cup member 2 , and allows the cleaning liquid to escape through the gap between the upper surface of the mounting base 201 and the cup member 2 .

[0039] A drop prevention protrusion 221 is formed between the mounting base 201 and the sink 202 to prevent the cup member 2 from dropping into the sink 202 .

[0040] A plurality of second spray nozzles 230 are formed on the edge of the stand 201, and two second light germicidal lamps 231 are formed adjacent to the second spray nozzles 230.

[0041] The second spray nozzle 230 is oriented to spray a cleaning liquid toward the base 201 to clean the base 201 with the cleaning liquid before or after the cleaning operation. The second light germicidal lamp 231 irradiates the base 201 with ultraviolet light simultaneously with the cleaning operation of the second spray nozzle 230 or before or after the cleaning operation to sterilize the base 201 with ultraviolet light.

[0042] FIG. 4 is a diagram showing the configuration of the lower module 20 of the washer 1 connected to the sterilization / washing unit 200. As shown in FIG.

[0043] As shown in FIG. 4, the lower module 20 includes a water tank 700 and a water purification device 800 .

[0044] Hoses 701, 702, and 703 are connected to a water tank 700. The hose 701 is connected to a first jet nozzle 210, and the hose 702 is connected to a second jet nozzle 230. In addition, the hose 703 is connected to a water supply pipe 704 through a valve 711.

[0045] Hoses 705 and 706 are connected to the water purification device 800. The hose 701 is connected to the drain outlet 203, and the hose 706 is connected to the hose 703 and the sewer pipe 707 through a valve 712.

[0046] Fresh water supplied from a water supply is stored in the water tank 700. The water tank 700 may be provided with a water purification / sterilization system for purifying or sterilizing the stored fresh water.

[0047] When performing a cleaning operation through the first spray nozzle 210, the control device operates a pump (not shown) to supply fresh water from the water tank 700 through a hose 701 to the first spray nozzle 210 and spray it. When performing a cleaning operation through the second spray nozzle 230, the control device operates a pump (not shown) to supply fresh water from the water tank 700 through a hose 702 to the second spray nozzle 230 and spray it.

[0048] According to the present embodiment, it is intended to use the fresh water stored in the water tank 700 as the cleaning liquid, but the present invention is not limited to this. For example, a cleaning liquid tank containing detergent may be provided in the upper module 10 or the lower module 20, and the control device may cause the cleaning liquid containing the detergent to be sprayed as the cleaning liquid from the first spray nozzle 210 and the second spray nozzle 230 as necessary. That is, in this specification, the term "cleaning liquid" is a concept that includes both fresh water and / or cleaning liquid containing cleaning components such as detergent.

[0049] Hoses 701, 702 connected to the water tank 700 and a hose connected to the cleaning liquid tank are connected to the first spray nozzle 210 and the second spray nozzle 230 through valves (not shown), and the control device may selectively spray fresh water or cleaning liquid through the first spray nozzle 210 and the second spray nozzle 230 by operating the valves as necessary.

[0050] The cleaning liquid discharged through the drain outlet 203 flows into the water purification device 800 via a hose 705, and the water purification device 800 purifies and sterilizes the flowed-in cleaning liquid with clean water.

[0051] The fresh water that has been purified / sterilized by the water purification device 800 flows out through hose 706, and the control device operates valve 712 to allow the fresh water to flow into the water tank 700 through hose 703. That is, the washer 1 can reuse the used washing solution after purifying / sterilizing it in the water purification device 800. When fresh water flows from the water purification device 800 into the water tank 700, the control device may operate valve 711 to prevent fresh water from flowing in from the water supply pipe 704.

[0052] If the control device determines that the water purification device 800 has not sufficiently purified / sterilized the water, the control device may discharge the cleaning liquid through the valve 712 into the sewer pipe 707 rather than reusing the cleaning liquid.

[0053] According to the present embodiment, the configuration including the water tank 700 and the water purification device 800 has been described, but the present invention is not limited to this. The water tank 700 and the water purification device 800 may be omitted, and the water supply pipe 704 may be directly connected to the spray nozzle to supply clean water, or the washing liquid discharged into the drain 203 may be disposed of in the sewer pipe 707.

[0054] Also, the washer 1 may be formed so that the water tank 700 is removable, without being connected to the water supply pipe 704 and the sewer pipe 707. That is, the washer 1 may be installed in a place where it cannot be directly connected to water supply and sewerage pipes, and may be operated by filling the water tank 700 with fresh water, operating it a predetermined number of times, and then refilling the water tank 700 again. In this case, by reusing the washing liquid through the water purification device 800, the number of times of use can be increased even in an environment where clean water is not supplied.

[0055] 5 and 6 are diagrams for explaining the support unit 300 and the lifting unit 400. FIG.

[0056] As shown in FIGS. 5 and 6, the support unit 300 includes a support member 310 .

[0057] The support member 310 includes four lateral ribs, a first lateral rib 301, a second lateral rib 302, a third lateral rib 303, and a fourth lateral rib 304, which are arranged in sequence and spaced apart from one another, and a plurality of vertical ribs 305 connecting the first lateral rib 301 to the fourth lateral rib 304. According to this embodiment, the ribs 301 to 305 are thin, rod-shaped iron members, and the lateral ribs 301 to 304 and the vertical rib 305 are fixed together by welding.

[0058] The first lateral rib 301 is formed in a closed semicircular shape, the second lateral rib 302 and the third lateral rib 303 are formed in a circular shape, and the fourth lateral rib 304 is formed in an open semicircular shape.

[0059] If the semicircle formed by the first lateral rib 301 and the fourth lateral rib 304 is assumed to be a perfect circle, the area of ​​the circle formed by each rib increases from the first lateral rib 301 to the fourth lateral rib 304.

[0060] That is, according to this embodiment, the support member 310 is formed with thin rod-like members 301 to 305 as a skeleton, and has a basket shape with a cross-sectional area that narrows downward.

[0061] Therefore, the support member 310 is formed with a recessed mounting portion 312 suitable for mounting the tumbler lid 3 thereon (see FIG. 8). More specifically, since the support member 310 has a shape in which the cross-sectional area narrows downward, a threaded portion having a smaller diameter than the body formed at the lower end of the tumbler lid 3 can be appropriately mounted on the mounting portion 312 of the support member 310. Furthermore, by forming the fourth lateral rib 304, which has the largest diameter, into an open semicircular shape, tumbler lids 3 of various shapes can be easily mounted on the support member 310.

[0062] Meanwhile, since the support member 310 is formed using a thin rod-shaped member as a skeleton, wide cleaning liquid passing holes 311 are formed between the ribs. The ribs 301-305 forming the support member 310 support the tumbler lid 3 while allowing the cleaning liquid sprayed from the first spray nozzle 210 to pass through the support member 310 via the cleaning liquid passing holes 311 to clean the tumbler lid 3. In addition, ultraviolet light irradiated from the first light germicidal lamp 240 reaches the tumbler lid 3 via the cleaning liquid passing holes 311, enabling light sterilization.

[0063] The support unit 400 includes a lifting device 410 for lifting and lowering the support member 310 .

[0064] The lifting device 410 includes a support plate 404 extending upward from the mounting base 201, a screw shaft 402 fixed to the support plate 404 so as to extend in the vertical direction, a motor 401 that rotates the screw shaft 402, and a guide shaft 403 that extends in the same direction as the screw shaft 402.

[0065] A nut member 406 having a spiral formed on its inner surface that meshes with the spiral on the outer surface of the screw shaft 402 is fastened to the screw shaft 402, and a guide shaft 403 passes through and is coupled to the nut member 406.

[0066] A moving block 405 is connected to the nut member 406 so as to extend in the direction of the support member 310 .

[0067] An extension member 320 having a predetermined length is welded and fixed to the support member 310 so as to extend toward the moving block 405. The extension member 320 is fixed to the moving block 405 by a fastening means.

[0068] 2, the lifting device 410 is hidden from the sterilization / cleaning unit 200 by a shielding plate 420. Slits 421 are formed at the top and bottom of the shielding plate 420, and the moving block 405 extends through the slits 421 toward the internal space 131. A support member 310 is fixed to the end of the moving block 405 exposed to the internal space 131.

[0069] 5 and 6 again, when the screw shaft 402 is rotated by the motor 401, the nut member 406 is prevented from rotating together with the screw shaft 402 by the guide shaft 403, and moves up and down along the screw shaft 402. As the nut member 406 moves up and down, the moving block 405 moves up and down, and the extension member 320 and the support member 310 fixed to the moving block 405 can move up and down.

[0070] A flange 408 is formed on the upper end of the support plate 404, and a limit switch 500 is formed on the upper surface of the moving block 405. The limit switch 500 includes a main body 501 and a switch member 502 that is hinged to the main body.

[0071] When the moving block 405 rises to its maximum position, the switch member 502 comes into contact with the flange 408 and is pressed. The control device can detect that the moving block 405 has reached its maximum position (i.e., the support member 310 has reached its maximum position) through a change in resistance within the body 501 when the switch member 502 is pressed. Of course, the control device can calculate the up and down positions of the moving block 405 through the rotation angle or number of rotations (i.e., the rotation state) of the motor 401. At this time, when the limit switch 500 is activated, the corresponding moment is reset as the rotation state of the motor 401 at the maximum position of the moving block 405, and position measurement errors occurring during operation can be corrected.

[0072] According to this embodiment, whether or not the moving block 405 has reached the lowest position (i.e., when the support member 310 is at its maximum position) is detected by the rotation state of the motor 401, but a configuration similar to the limit switch 500 may also be arranged at the lower end of the support plate 404 for detection.

[0073] 6, a socket 407 is formed on the upper surface of a moving block 405 to serve as a support point for supporting an extension member 320, and a pressure detection sensor 600 is formed on the opposite side of the socket 407 to the support member 310.

[0074] A through hole is formed in the extension member 320, and the bolt 408 is inserted through the through hole and fastened to the socket 407. The extension member 320 extends from the support member 310, and is formed such that an end of the extension member 320 extends beyond the socket 407.

[0075] The diameter of the through hole of the extension member 320 is slightly larger than the outer diameter of the bolt 408. In this case, in order to prevent the extension member 320 from swinging relative to the bolt 408, two elastic bodies 331, 332 are fitted between the extension member 320 and the bolt 408, one above the other. According to this embodiment, the elastic bodies 331, 332 are O-rings that fit onto the bolt 408.

[0076] The elastic bodies 331 and 332 are positioned above and below the through-hole of the extension member 320, and the bolt 408 is inserted into the through-hole of the extension member 320 and firmly tightened. As a result, the extension member 320 is fixed to the moving block 405 via the elastic bodies 331 and 332.

[0077] As long as no external force is applied, the elastic bodies 331 and 332 have sufficient rigidity to withstand the load of the support member 310. Therefore, in the process in which the support member 310 is raised and lowered by the moving block 405, the extension member 320 does not swing or tilt with respect to the socket 407, which is the support point.

[0078] On the other hand, when a force sufficient to elastically deform the elastic bodies 331 and 332 is applied, the elastic bodies 331 and 332 are elastically deformed, allowing the extension member 320 to perform a kind of seesaw motion based on the support point. In other words, when a force sufficient to elastically deform the elastic bodies 331 and 332 is applied, the support member 310 and the extension member 320 are allowed to tilt with respect to the moving block 405.

[0079] More specifically, as described below, when cleaning the cup member 2, the control device lowers the support member 310 and presses the underside of the cup member 2 placed upside down against the support member 310, thereby preventing the cup member 2 from falling over or shaking due to the pressure of the cleaning liquid.

[0080] After the support member 310 descends and the lower surface of the support member 310 comes into contact with the cup member 2, the moving block 405 continues to descend due to the motor 401 for a short moment.

[0081] Therefore, in response to the force with which the support member 310 presses down on the cup member 2, a reaction force is applied from the cup member 2 to the support member 310, whereby the cup member 2 presses up on the support member 310.

[0082] If the extension member 320 fixed to the support member 310 is rigidly fixed to the moving block 405, there is a risk that the extension member 320 may bend or break. However, according to this embodiment, the extension member 320 is fixed to the moving block 405 via elastic bodies 331 and 332.

[0083] Therefore, when a force acts to lift the support member 310 upward in reaction to the force of the support member 310 pressing down on the bottom surface of the cup member 2, a force acts to tilt the extension member 320, compressing the elastic bodies 331 and 332. When a sufficient force acts, the elastic bodies 331 and 332 elastically deform, allowing the extension member 320 to make a seesaw motion based on the support point without bending or breaking. In other words, the elastic bodies 331 and 332 elastically deform, allowing the support member 310 and the extension member 320 to tilt relative to the moving block 405.

[0084] Therefore, by allowing the support member 310 and the extension member 320 to tilt with respect to the moving block 405, it is possible to prevent the multi-use cup made of a thin plastic material from being pushed by the support member 310 and damaged.

[0085] Furthermore, according to this embodiment, the support member 310 and the extension member 320 are supported using an elastic body, and the pressing state of the support member 310 against the cup member 2 is detected using a structure that allows tilting relative to the moving block 405 under specified conditions.

[0086] According to this embodiment, a pressing member 330 is coupled to the lower surface of the end of the extension member 320 extending on the opposite side to the support member 310, and a pressing detection sensor 600 is disposed below the pressing member 330. The pressing detection sensor 600 is a sensor that detects the pressing state of the support member 310 against the cup member 2.

[0087] According to this embodiment, the pressure detection sensor 600 is a switch-type sensor, and includes a main body 601 and a switch 602 protruding from the upper end of the main body 601 .

[0088] When the support member 310 comes into contact with the cup member 2 and presses down the cup member 2, the elastic bodies 331, 332 are elastically deformed, as described above, and the support member 310 and the extension member 320 become inclined relative to the moving block 405.

[0089] As a result, the end of the extension member 320 descends, and the pressing member 330 comes into contact with the switch 602 and presses down the switch 602. The control device detects the change in resistance inside the main body 601 as the switch 602 is pressed, and detects the pressing state of the support member 310 and the cup member 2.

[0090] According to the present embodiment, the pressure detection sensor 600 is exemplified as a switch type sensor that is activated when the switch is pressed down while the extension member 320 is tilted, but is not limited thereto. For example, an image sensor may be used to detect that the extension member 320 has come closer to the sensor than a predetermined distance, and thus it may be detected that the support member 310 has pressed down the cup member 2 and tilted it.

[0091] However, using a mechanically actuated switch type sensor can reduce manufacturing costs.

[0092] Also, a switch-type sensor can be disposed at the lower end of the support member 310, and when the support member 310 comes into contact with the cup member 2, the switch can be directly pressed by the cup member 2 to detect the pressed state. However, according to this embodiment, by providing the pressure detection sensor 600 in a portion hidden by the shielding plate 420, it is possible to prevent the sensor from malfunctioning due to the cleaning liquid, and to prevent the cleaning liquid and ultraviolet rays from reaching the tumbler lid 3 due to the sensor hiding the lower end of the support member 310.

[0093] Hereinafter, the operation of the washer 1 will be described with reference to FIGS.

[0094] FIG. 7 is a diagram for explaining the cleaning mode of the cup member 2, and FIG. 8 is a diagram for explaining the cleaning mode of the tumbler lid 3.

[0095] The control device displays a virtual switch for selecting the start of cleaning on the touch screen 111 and waits. At this time, the support member 310 is placed at the top. With the limit switch 500 in operation, this position is set as the reference position for the highest position of the motor 401.

[0096] When the control device detects that the user has touched the virtual switch to start washing, the control device displays virtual switches on the touch screen 111 for selecting the "cup washing mode," "tumbler washing mode," and "lid washing mode."

[0097] Since the cup washing mode and the tumbler washing mode have substantially the same washing operation, the cup washing mode and the tumbler washing mode may not be distinguished from each other and may simply be integrated into the cup member washing mode for display.

[0098] However, since a multiple-use cup is generally less rigid than a tumbler, the control device may control the motor 401 more precisely in the cup washing mode than in the tumbler washing mode to prevent the multiple-use cup from being damaged by the support member 310.

[0099] When the user selects one of the cup washing mode, the tumbler washing mode, and the lid washing mode, for example, the control device displays virtual switches for selecting a "washing process," a "washing and rinsing process," a "sterilization process," and an "integrated process." The "washing process" is a process of washing using clean water, the "washing and rinsing process" is a process of washing using a cleaning solution containing detergent and rinsing with clean water in sequence, the "sterilization process" is a process of sterilization using the first light sterilization lamp 240, and the "integrated process" is a process of washing, washing, and sterilization all performed.

[0100] However, this is merely an example, and if there is no cleaning liquid injection function, the "Cleaning Process", "Sterilization Process" and "Integration Process" may be selected, or the cleaning (cleaning and washing) and sterilization processes may be performed without fail, and the process selection operation may be omitted.

[0101] For example, when the user selects the cup cleaning mode and the integration process, the control device guides the user to open the door 120, turn the cup member 2 upside down, and place the cup member 2 into the internal space 131 so that the first spray nozzle 210 is located inside. The guidance may be given by voice or may be displayed as a visual graphic through the touch screen 111.

[0102] When the user positions the cup member 2 and touches the start button displayed on the touch screen 111 , the controller closes the door 120 .

[0103] As shown in FIG. 7, when the door 120 is closed, the control device lowers the support member 310 so that the support member 310 presses against the lower surface of the cup member 2 to fix it in place.

[0104] The control device first injects the cleaning liquid through the first injection nozzle 210, and when the cleaning liquid injection process for a predetermined time is completed, it injects clean water to wash the surface. After the clean water rinsing is completed or while the clean water rinsing is in progress, the first light sterilization lamp 240 is operated to perform the sterilization process.

[0105] The controller may display a virtual image corresponding to each step through the touch screen 111 while the step is being performed.

[0106] When the process is completed, the control device raises the support member 310 to the top and guides the user to retrieve the cup member 2 after opening the door 120.

[0107] When the user withdraws the cup member 2, the control device closes the door 120 and activates the second spray nozzle 230 and the second light germicidal lamp 231 to sterilize / clean the mounting base 201 and the internal space 131.

[0108] For example, when the user selects the lid washing mode and the integration process, the control device lowers the support member 310 to the lowest position so that the first injection nozzle 210 and the support member 310 are positioned closest to each other, as shown in FIG.

[0109] The control device then guides the user to open the door 120 and place the lid 3 upright on the support member 310. The guidance may be provided by voice or by displaying visual graphics via the touch screen 111.

[0110] When the user places the lid 3 in position and touches the start button displayed on the touch screen 111, the controller closes the door 120.

[0111] The control device first injects the cleaning liquid through the first injection nozzle 210, and when the cleaning liquid injection process for a predetermined time is completed, clean water is injected to wash the surface.

[0112] According to this embodiment, the top injection hole 211 and the side injection hole 212 of the first injection nozzle 210 can be selectively activated through a valve (not shown), and in the lid cleaning mode, only the top injection hole 211 may be activated to spray cleaning liquid.

[0113] After the fresh water rinsing is completed or while the fresh water rinsing is in progress, the first light sterilizing lamp 240 is operated to perform the sterilization process.

[0114] The controller may display a virtual image corresponding to each step through the touch screen 111 while the step is being performed.

[0115] Once the entire process is completed, the control device will open the door 120 and guide the user to retrieve the lid 3 .

[0116] When the user removes the lid 3, the control device closes the door 120, raises the support member 310 to the top, and activates the second spray nozzle 230 and the second light germicidal lamp 231 to sterilize / clean the mounting base 201 and the internal space 131.

[0117] The washing machine 1 according to this embodiment is capable of automatically washing cups, tumblers, tumbler lids and other cups, and is highly usable as a multi-purpose washing machine.

[0118] Furthermore, when the cup member 2 is pressed through the support member 310, the support member 310 is permitted to tilt slightly, so that the cup member 2 can be prevented from being damaged by the pressure of the support member 310.

[0119] Furthermore, since the pressure detection sensor is operated using a configuration that allows the support member 310 to be tilted, the contact and pressing state of the support member 310 against the cup member 2 can be detected with a simple configuration, and the washer 1 can be effectively controlled.
