Description

cup washer

[0001] The present invention relates to a cup washer, and more particularly, to a cup washer that washes a cup by spraying water.

[0002] A cup washer is a device that sprays water to clean cups. Recently, as awareness of carbon neutrality has spread throughout society, the number of people carrying personal or reusable cups has increased. Consequently, more and more government offices, companies, and stores are installing cup washer machines to ensure hygiene and convenience for their customers (and employees).

[0003] With regard to technology for washing dishes such as cups, Korean Patent Publication No. 2012-0107225 (hereinafter referred to as "Prior Document 1") discloses a "Rack of Dishwashing Machine," wherein the rack of the dishwashing machine includes a distance-adjusting member whose length can be adjusted. The distance-adjusting member has a plurality of support members. The distance-adjusting member adjusts the distance between the support members, and an object to be washed is placed between the support members.

[0004] The distance adjustment member is provided with a movable distance fixing member. It also includes a fixing bar that can fix the position of the distance fixing member. The user can adjust the distance between the supports by moving the distance fixing member to suitably adjust the distance between the supports, and then fix the position of the distance fixing member to adjust the distance between each support.

[0005] According to the above prior art document 1, since the distance between each support is adjusted to simply accommodate objects of various sizes and shapes between the supports, there is a limit to preventing objects to be washed placed on the rack from tipping over during the washing process. Furthermore, since the rack is designed to only perform the function of simply placing objects to be washed, such as dishes, the usability of the rack is limited.

[0006] Regarding technology utilizing a rack (basket), Korean Patent Publication No. 2014-0064119 (hereinafter referred to as "Prior Document 2") discloses a "dishwasher." The dishwasher comprises a washing tank, a basket, a frame, a catch, and a control unit. The washing tank forms a space in which dishes are washed. The frame is positioned within the washing tank and accommodates a basket. The control unit is positioned on the side of the frame and adjusts the height of the basket.

[0007] According to the above prior art document 2, the capacity of the upper space of the basket can be adjusted by adjusting the height of the basket according to the user's needs, so that a vertically long tumbler or cup can be placed in the basket. However, since the basket is made of a simple mesh net, there is a limit to preventing the items to be washed placed on the rack from falling over during the washing process. In addition, according to the above prior art document 2, the position of the placed cup or other tableware cannot be fixed, so the sprayed water may not reach the entire inner and outer surfaces of the cup or other tableware.

[0008] The present invention aims to solve the above problems of a cup washing machine that washes a cup by spraying water.

[0009] Specifically, the purpose is to provide a cup washer that diversifies the functions of the rack, prevents the cup from tipping over, allows the cup lid to be placed, and enhances the mixing of water and additives while the rack is seated within the tub.

[0010] In addition, the present invention aims to provide a cup washer in which the tub and rack are custom designed to prevent misassembly of the rack within the tub.

[0011] In addition, the present invention aims to provide a cup washer in which washing water can be accurately sprayed onto a cup and a cup lid while the rack is seated within the tub by optimizing the position of the washing water spray within the tub.

[0012]

[0185] Fig. 11 is a perspective view of a rack (200) according to an embodiment of the present invention.

[0186] Fig. 12 is a plan view of the washing space inside the tub (100) of Fig. 6 as viewed from above, and is a drawing showing a state in which the rack (200) is pulled out from within the tub (100).

[0187] The internal space of the tub (100) may form a three-dimensional shape. For example, the internal space of the tub (100) may form an approximately hexahedral shape. In this case, the inner wall surface (110) of the tub (100) may include a first inner wall surface (111), a second inner wall surface (112), a third inner wall surface (113), and a fourth inner wall surface (114).

[0188] And the inner wall surface of the tub (100) may include a first corner surface (115), a second corner surface (116), a third corner surface (117), and a fourth corner surface (118). The first corner surface (115) may refer to a wall surface connecting the first inner wall surface (111) and the second inner wall surface (112). The second corner surface (116) may refer to a wall surface connecting the second inner wall surface (112) and the third inner wall surface (113). The third corner surface (117) may refer to a wall surface connecting the third inner wall surface (113) and the fourth inner wall surface (114). The fourth corner surface (118) may refer to a wall surface connecting the fourth inner wall surface (114) and the first inner wall surface (111).

[0189] A step portion (106) may be formed along the horizontal direction on the inner wall surface (110) of the tub (100). The step portion (106) may be formed along the first inner wall surface (111), the second inner wall surface (112), the third inner wall surface (113), and the fourth inner wall surface (114). The step portion (106) may be formed on some or all of the first corner surface (115), the second corner surface (116), the third corner surface (117), and the fourth corner surface (118).

[0190] A rack (200) on which a cup (C) and a cup lid (Ca) are placed may be provided in the washing space. The rack (200) may be inserted into or taken out of the washing space through a cup inlet. The cup (C) and the cup lid (Ca) may be spaced apart from the inner surface of the tub (100) while placed on the rack (200). The cup (C) may be placed on the rack (200) in an upside-down state. The rack (200) may include a first cell (210), a second cell (220), a third cell (230), and a fourth cell (240).

[0191] The first cell (210) can be mounted on the inner wall (110) of the tub (100). The first cell (210) can be formed in a wire shape that is bent horizontally so as to be mounted on the step portion (106). The first cell (210) can be formed in a closed loop shape that is bent horizontally multiple times.

[0192] For example, when the slit portion (106) is formed along the first inner wall surface (111), the second inner wall surface (112), the third inner wall surface (113), and the fourth inner wall surface (114), the first cell (210) can form a closed loop shape that is bent four times in the horizontal direction. That is, the first cell (210) can include four bent portions (hereinafter, 'bent portions').

[0193] The bending portion may include a first bending portion (211) bent with a first radius (r1), and a second bending portion (212) bent with a second radius (r2) greater than the first radius (r1). The first bending portion (211) may be positioned on each of the rear sides of the first cell (210), and the second bending portion (212) may be positioned on each of the front sides of the first cell (210).

[0194] The second cell (220) can be coupled to the first cell (210). The second cells (220) can be provided in multiple numbers.

The second cells (220) can include a cup mounting portion (221) on which the opening of the cup (C) is mounted, and a cup support portion (222) that supports the side of the cup (C). The cup mounting portion (221) can form a downward slope toward the front. The cup support portion (222) can form an upward slope toward the front. Therefore, the cup (C) can be placed in a forwardly tilted state (see FIG. 6).

[0195] The third cell (230) may be coupled to the first cell (210). The third cell (230) may include a third a cell (231) and a third b cell (232). The third a cell (231) and the third b cell (232) may form a space between them in which a cup lid (Ca) is placed. The washing water spray port (105) may be formed on the fourth inner wall (114). The third cell (230) may place the cup lid (Ca) forward of the spray direction of the washing water spray port (105). The cup lid (Ca) may be placed on the rack (200) right in front of the washing water spray port (105) (see FIG. 6). Therefore, the cup lid (Ca) placed on the rack (200) may be cleanly washed by the washing water supplied from the washing water supply unit (90).

[0196] The fourth cell (240) can reinforce the structural rigidity of the rack (200) by connecting the second cells (220) and the third cell (230).

[0197] Fig. 13 is a partial perspective view of the inner wall surface (110) of the tub (100) of Fig. 12, showing the wall protrusion (107).

[0198] Fig. 14 is a plan view of the washing space inside the tub (100) of Fig. 6 as viewed from above, and is a drawing showing a state in which a rack (200) is installed inside the tub (100).

[0199] A wall protrusion (107) protruding into the tub (100) may be formed on the inner wall (110) of the tub (100). The wall protrusion (107) may be formed in a shape extending upwards from the step (106) by a certain height. The wall protrusion (107) may protrude into the tub (100) from a corner surface. For example, the wall protrusion (107) may protrude into the tub (100) from a first corner surface (115) and a second corner surface (116).

[0200] When the rack (200) is placed in the tub (100) in a correct posture, the second bent portion (212) bent with a second radius (r2) larger than the first radius (r1) may not be caught on the wall protrusion (107). Accordingly, the first cell (210) may be placed in a correct posture on the step portion (106). Accordingly, the cup lid (Ca) may be placed on the rack (200) right in front of the washing water spray port (105) (see FIG. 6). Accordingly, the cup lid (Ca) placed on the rack (200) may be cleaned by the washing water supplied from the washing water supply unit (90).

[0201] However, when the rack (200) is placed in the tub (100) in a position other than the upright position, the first cell (210) may be caught on the wall protrusion (107) and spaced apart from the step (106). For example, when the rack (200) is placed in the tub (100) in a position rotated 180 degrees around the Z-axis, the first bent portion (211) bent with a first radius (r1) smaller than the second radius (r2) may be caught on the wall protrusion (107) and spaced apart from the step (106). Therefore, the user can easily recognize that the rack (200) is placed in the tub (100) in a position other than the upright position.

[0202] Fig. 15 is a partial perspective view of the rack (200) of Fig. 11, showing the cup holder portion (280).

[0203] A cup washer (1000) according to an embodiment of the present invention may include a cup gripping part (280) that grips an opening of a cup (C).

[0204] The grip body (281) can be detachably coupled to the rack (200). The grip body (281) can be detachably coupled to the second cells (220). The grip body (281) can include a first grip portion (281a) into which the cup support portion (222) is detachably fitted, and a second grip portion (281b) into which the cup mounting portion (221) is detachably fitted. The grip body (281) can be detachably coupled to the second cells (220) at a portion where the cup mounting portion (221) and the cup support portion (222) are connected.

[0205] The flip part (282) can be extended from the grip body (281). The opening of the cup (C) can be fitted between the grip body (281) and the flip part (282). The flip part (282) can be elastically deformed and grip the opening of the cup (C) together with the grip body (281). Therefore, the cup (C) can be firmly maintained in a state where it is tilted forward (see Fig. 6).

[0206] Fig. 16 is a partial perspective view of the rack (200) of Fig. 11, showing a mixing guide (270).

[0207] Figure 17 is a partial enlarged view of Figure 6, showing a washing water inlet pipe, an additive transfer pipe (640), and a mixing guide (270).

[0208] Fig. 18 is a drawing of a mixing guide (270) viewed from the first area of ​​the inner wall (110) of the tub (100).

[0209] A cup washer (1000) according to an embodiment of the present invention may include a mixing guide (270) that guides water introduced into the tub (100) through the washing water inlet (102) toward the additive inlet (103).

[0210] The mixing guide (270) can be detachably coupled to the rack (200). The mixing guide (270) can be detachably coupled to the second cells (220). The mixing guide (270) can include a pair of guide grip portions (273) into which the second cells (220) are detachably fitted. In a state where the second cells (220) are fitted to the pair of guide grip portions (273), the lower portion of the mixing guide (270) can be brought into close contact with the first cell (210) or the fourth cell (240). Therefore, the mixing guide (270) can be firmly maintained in a detachably coupled state to the rack (200).

[0211] The mixing guide (270) can form a mixing space (270a) through which water moves between the first region (104) and is mixed with the additive (Ag). The mixing space (270a) can be formed in front of the first region (104). The mixing guide (270) can include a front guide (271) and a side guide (272).

[0212] In a state where the first cell (210) is positioned on the step portion (106), the front guide (271) can be spaced apart from the first region (104) by a certain distance. The front guide (271) can form a surface facing the first region (104) with the mixing space (270a) therebetween.

[0213] In a state where the first cell (210) is secured to the step portion (106), the side guide (272) can form a shape that surrounds the first region (104) from the upper and side sides of the first region (104). Accordingly, the mixing space (270a) can be opened downward within the tub (100). Accordingly, the mixing guide (270) can guide water that has flowed into the tub (100) through the washing water inlet (102) toward the additive inlet (103).

[0214] Water discharged from the washing water inlet (102) can pass through the first region (104) and fall into the tub (100) from the lower portion of the mixing guide (270). The water discharged from the washing water inlet (102) can form a constant flow rate in the mixing space (270a). Therefore, the additive discharged into the tub (100) from the additive inlet (103) can be quickly mixed into the water discharged from the washing water inlet (102) in the mixing space (270a).

[0215] Fig. 19 is a perspective view of a rack (200) according to an embodiment of the present invention.

[0220] The second cell (220) can be coupled to the first cell (210). The second cells (220) can be provided in multiple numbers. The multiple second cells (220) can be positioned above the first cell (210). The second cells (220) can include a cup mounting portion (221) on which the opening of the cup (C) is mounted, and a cup support portion (222) that supports the side surface of the cup (C). The cup mounting portion (221) can form a downward slope toward the front. The cup support portion (222) can form an upward slope toward the front. Therefore, the cup (C) can be placed in a state of being tilted forward.

[0221] The third cell (230) can be coupled to the first cell (210). The third cell (230) can include a third a cell (231) and a third b cell (232). The third a cell (231) and the third b cell (232) can form a space between them in which a cup lid (Ca) is placed. The third a cell (231) and the third b cell (232) can be somewhat elastically bent and firmly maintain the state in which the cup lid (Ca) is placed.

[0222] The fourth cell (240) can reinforce the structural rigidity of the rack (200) by connecting the second cells (220) and the third cell (230).

[0225] The flip portion (282) can be extended from the grip body (281). The opening of the cup (C) can be fitted between the grip body (281) and the flip portion (282). The flip portion (282) can be elastically deformed and grip the opening of the cup (C) together with the grip body (281). Therefore, the cup (C) can be firmly maintained in a state in which it is placed while tilted forward.

[0226] A cup washer (1000) according to an embodiment of the present invention may include a mixing guide (270) that guides water introduced into the tub (100) through the washing water inlet (102) toward the additive inlet (103).

[0227] The mixing guide (270) can be detachably coupled to the rack (200). The mixing guide (270) can be detachably coupled to the second cells (220). The mixing guide (270) can include a pair of guide grip portions (273) into which the second cells (220) are detachably fitted. In a state where the second cells (220) are fitted to the pair of guide grip portions (273), the lower portion of the mixing guide (270) can be brought into close contact with the first cell (210) or the fourth cell (240). Therefore, the mixing guide (270) can be firmly maintained in a detachably coupled state to the rack (200).

[0228] The mixing guide (270) can form a mixing space (270a) between the first region (104) and the mixing space (270a) through which water moves and mixes with the additive.
