Description

[Technical Field]

[0001] The present invention relates to a tumbler washing machine, and more particularly to a machine that automatically washes and rinses the cup, lid, and straw that make up a tumbler while they are separate from each other. [Background technology]

[0002] In general, coffee shops and other establishments are seeing a rapid increase in the use of personal cups, or tumblers, in order to reduce environmental pollution caused by disposable cups. Tumblers consist of a cup and a lid that covers the open part of the cup to protect the drinking water. Not only do they keep the drinking water hot or cold, but recently sets of cup and lid, complete with a tumbler straw, have become available, and many people are purchasing these sets for personal use.

[0003] Tumblers are used to store and consume various beverages, such as coffee, provided or sold in public places or specialty beverage stores, and are not disposable but must be carried around and reused while traveling, so hygiene management, along with proper cleaning, is extremely important.Tumblers generally have a narrow diameter and a deep cup shape, making them more difficult to clean than regular tableware or containers.

[0004] Conventionally, cups are simply washed in the dishwasher together with other food containers before being used, but public places or specialty beverage stores have not provided a device for simultaneously washing cups and straws including lids.

[0005] Therefore, users have to personally wash the cups one by one and then pour drinking water into them, but since tumblers have a narrow diameter and a deep cup shape, it is difficult to wash them by hand, which is inconvenient and unhygienic to manage. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to overcome these conventional drawbacks, the object of the present invention is to provide a tumbler washer that allows both washing and rinsing to be performed with the cup, lid, and straw simply attached, thereby enabling the tumbler to be used repeatedly in a hygienic manner.

[0007] Another object of the present invention is to provide a tumbler washer that can be installed in public facilities and various drinking water stores, allowing users to easily and quickly wash drinking water before pouring it into a cup, thereby providing convenience to users.

[0008] Another object of the present invention is to provide a tumbler washer that can achieve service effects and sales promotion effects through sanitation management.

[0009] Another object of the present invention is to provide a tumbler washer that is highly safe by preventing hot water remaining on the ceiling from falling on the hands when removing the tumbler after washing is completed, thereby preventing injury or inconvenience. [Means for solving the problem]

[0010] In order to achieve the above-mentioned object, the present invention provides a tumbler washer including a housing, a door connected to the front opening of the housing, a bracket attached to the inner surface of the door, a washing unit connected to the bracket and washing the cup and lid of the tumbler, respectively, and a plurality of nozzles arranged on at least a part of the upper and lower parts of the housing and spraying washing water and rinsing water toward the washing unit, respectively.

[0011] The cleaning unit preferably includes a lid chamber for accommodating a tumbler lid, and a cup holder for seating a tumbler cup.

[0012] The lid chamber and the cup setting table are preferably linked to each other by a power transmission means.

[0013] The cup setting table is preferably arranged on a support attached to the bracket so as to be rotatable along an axis in a vertical direction, and a gear is preferably formed along the periphery of the lower outer periphery of the cup setting table.

[0014] The power transmission means may include a first pulley coupled to one side of the cover chamber, a second pulley arranged on one side of the cup setting stand to be rotatable about an axis perpendicular to the rotation direction of the cup setting stand and having teeth formed on an outer circumferential surface to be gear-coupled with the gear, and a belt connected to each of the first pulley and the second pulley to transmit power.

[0015] The cleaning unit may further include a coil spring for inserting a straw, the coil spring being vertically disposed by a support connected to the bracket.

[0016] The cover chamber may include support discs arranged opposite to each other, a plurality of hinge shafts arranged between the support discs, and arc-shaped opening and closing plates that are hingedly coupled to the hinge shafts to be rotatable and have a plurality of openings formed therein so that washing water and rinsing water can be introduced therein.

[0017] Preferably, the opening and closing plate has a quadrant arc shape, the cover chamber is formed into a cylindrical shape by combining four opening and closing plates, a hinge part to be combined with the hinge shaft is formed on one side of the opening and closing plate, and a wing part to be in contact with the outer surface of the adjacent hinge shaft is integrally formed on the other side of the opening and closing plate.

[0018] The opening and closing plate is coupled to the hinge shaft so that an elastic force acts in the opening direction by a torsion spring disposed on the hinge shaft, and preferably contacts the door so as not to be opened or closed at positions other than the upper direction of the door by a plurality of guide rollers fixed to the bracket.

[0019] Preferably, the support disk has a circular engaging groove formed in multiple stages and spaced apart from one another so that the elastic force can be adjusted according to the engaging position of the end of the torsion spring.

[0020] The cup mounting base preferably includes a conical mounting member having a narrower diameter at the upper end than at the lower end, and a gear is formed around the lower outer periphery of the mounting member, and a plurality of drainage holes are preferably formed in the mounting member.

[0021] Preferably, a seating protrusion is formed on the outer inclined surface of the mounting member in an inclined direction, and a separation space is formed between the inclined surface and the inner surface of the tumbler cup to be seated.

[0022] Preferably, the cup setting table further includes a support rod connected to the center of the upper portion of the mounting member, and a cup holder connected to the upper end of the support rod. [Effects of the Invention]

[0023] In the present invention as described above, in particular, the unit for washing cups, lids, and straws is attached to the door and opens to the outside when the door is opened. The tumbler that has been washed is separated, and after a new tumbler that needs to be washed is installed, the door is closed and automatic washing, rinsing, removal of residual water, and sterilization are performed.

[0024] Tumbler washers with this function are installed in multiple rows on a cabinet-structured frame in public facilities or specialty drinking water stores, and can automatically clean all of the cups, lids, and straws just before the user pours in drinking water.

[0025] In particular, since the washing water and rinsing water are sprayed obliquely from directions intersecting each other, residual water is minimized by the spray water pressure, thereby enabling more hygienic washing and rinsing.

[0026] Therefore, it is possible to increase promotional and sales effects by improving service while being hygienic, and since the use of disposable cups can be eliminated, it has the effect of preventing environmental pollution and providing economic benefits.

[0027] In addition, after the cleaning process is completed, when removing the tumbler, it prevents the hot water remaining on the ceiling inside the housing from accidentally falling onto your hands, causing injury or inconvenience, and prevents any water from remaining in the cup, making it both safe and convenient.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The advantages and features of the present invention, and methods for achieving them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms. The present embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully convey the scope of the invention to those skilled in the art. The present invention is defined only by the scope of the claims. Furthermore, the terms used in this specification are for the purpose of describing the embodiments and are not intended to limit the present invention. In this specification, the singular form includes the plural form unless otherwise specified in the text. The words "comprise" and / or "having" used in this specification do not exclude the presence or addition of other elements other than the elements listed. Unless otherwise defined, all terms (including technical and scientific terms) used herein may have the meaning commonly understood by a person of ordinary skill in the art to which the present invention belongs. Hereinafter, in order to more specifically explain the present invention, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0030] 1 to 17 show the configuration of a tumbler washer according to an embodiment of the present invention. A tumbler is composed of a cup and a lid that covers the open top of the cup to protect drinking water. Recently, a cup and lid with a straw for the tumbler have been sold as a set, and many people have purchased this set and carried it with them for personal use. The tumbler washer of the present invention is installed, for example, in public facilities or specialty drinking water stores, and is a device that allows users to automatically clean the cup, lid, and straw just before pouring drinking water into the cup.

[0031] Fig. 2 shows an example of the external shape of a tumbler washing machine, Fig. 3 is a vertical cross-sectional view of the door 200 when it is closed, and Fig. 4 is a vertical cross-sectional view of the door 200 when it is opened, with the washing unit 400 attached via the bracket 300 rotating together, allowing the user to attach a cup, lid, and straw to the washing unit 400 or to remove it after washing is completed. Fig. 5 is a perspective view of the door 200 when it is fully opened from the housing 100.

[0032] The tumble washer according to one embodiment of the present invention may include a housing 100, a door 200, a bracket 300, a washing unit 400, and a nozzle 500. The housing 100 constituting the case may have a hollow rectangular shape with an open front, providing a space for washing and rinsing with various structures housed inside.

[0033] In one embodiment, a door 200 is rotatably coupled to the front opening of the housing 100 via a hinge 210. Alternatively, in another embodiment, a door (not shown) may be slidable forward and backward through the front opening of the housing. In this case, the cleaning unit may be rotated within a certain angle range by sliding the door.

[0034] The door 200 is a plate-shaped member of a certain thickness, and the center portion is made of transparent glass or acrylic material to allow the interior to be seen through, so that the washing and rinsing processes can be observed from the outside. A locking device can be installed to prevent the door 200 from being accidentally opened while it is closed for the washing and rinsing processes on the housing 100. Meanwhile, a bracket 300 is attached to the inside surface of the door 200.

[0035] The washing unit 400 is coupled to the bracket 300 and washes the cup and lid of the tumbler, respectively. In one embodiment, the washing unit 400 is fixedly installed using the bracket 300 attached to the inner surface of the door 200, so that the washing unit 400 can rotate within a certain angle range when the door 200 is opened or closed (FIGS. 4 and 5). This prevents injury or inconvenience caused by hot water remaining on the ceiling inside the housing 100 dripping onto hands when removing the tumbler after the washing process is completed.

[0036] The nozzle 500 is disposed in at least one of the upper and lower portions of the housing 100 and can spray washing water and rinsing water toward the cleaning unit 400. A plurality of nozzles 500 may be formed. In this case, the washing water and rinsing water sprayed from the nozzles 500 may be sprayed in an oblique direction.

[0037] The washing unit 400 accommodates the tumbler cup, lid, or straw, respectively, and allows washing and rinsing through the nozzle 500. The washing unit 400 may include a lid chamber 410 in which the tumbler lid is accommodated. The washing unit 400 may also include a cup mounting stand 420 on which the tumbler cup is mounted. The washing unit 400 may also include a lid chamber 410 in which the tumbler lid is accommodated and a cup mounting stand 420 on which the tumbler cup is mounted. In this case, the lid chamber 410 and the cup mounting stand 420 may be interconnected by a power transmission means 600.

[0038] The cleaning unit 400 may further include a straw insertion coil spring 430 that is vertically disposed by a support 431 coupled to the bracket 300. When a personal portable straw is inserted into the straw insertion coil spring 430, washing water and rinsing water sprayed from the nozzle 500 can penetrate through gaps in the coil spring 430 and come into contact with the straw, thereby enabling more effective washing and rinsing. In this case, the support 431 supports the lower end of the straw inserted into the straw insertion coil spring 430 to prevent the straw from falling.

[0039] 11, a separate holder 432 may be further installed at the bottom of the straw insertion coil spring 430 to prevent the straw from falling and shifting from the cleaning position. In this way, the holder 432 allows the straw to be positioned as far as possible at the bottom of the cleaning unit 400, allowing for further cleaning at the part that comes into contact with the user's mouth.

[0040] Fig. 6 is a perspective view of the main part of the washing unit 400, in which a plurality of nozzles 500 for spraying washing water and rinsing water are arranged at the top and bottom of the washing unit 400. Fig. 7 is a perspective view of the main part of the washing unit 400, in which the nozzles 500 are removed.

[0041] The lid chamber 410 is a container for washing the tumbler lid, and is configured by combining a plurality of opening and closing plates 411 to form a drum shape on one side of the bracket 300, i.e., inside the housing 100 (FIG. 10). The lid chamber 410 is installed in a state where it can rotate freely relative to the bracket 300 through a bearing (not shown).

[0042] Meanwhile, a driving motor M may be installed outside the housing 100. At this time, the power of the driving motor M is transmitted to a pinion 418, which is axially installed outside the cover chamber 410, via an intermediate gear 110, so that the cover chamber 410 can be rotated at a constant speed.

[0043] The drive motor M is a switch contact (not shown) that shorts electricity and stops rotation when the door 200 is opened from the housing 100, and operates as a switch contact with the interior cleaning space of the housing 100 sealed when the user rotates the door 200 in the closed state. At this time, when the lid chamber 410 rotates together with the pinion 418 in the direction in which the door 200 is opened, the pinion 418 is separated from the intermediate gear 110 as shown in Figure 4, and power is cut off. Then, when the door 200 is moved again in the closing direction, the pinion 418 and the intermediate gear 110 are gear-engaged as shown in Figure 3, and the rotational power of the drive motor M can be transmitted to the lid chamber 410.

[0044] The lid chamber 410 can be rotated by receiving power from a drive motor M installed outside the housing 100 when the housing 100 is sealed by closing the door 200. The lid chamber 410 can be rotated 360 degrees.

[0045] The cover chamber 410 according to one embodiment may include support discs 415 arranged opposite to each other, a plurality of hinge shafts 416 arranged between the support discs 415, and an arc-shaped opening / closing plate 411 that is hingedly coupled to each of the hinge shafts 416 to be rotatable and has a plurality of openings 412 formed therein so that cleaning water and rinsing water can be introduced therein. The opening / closing plate 411 may be manufactured by injection molding in a shape in which the openings are repeatedly formed.

[0046] According to one embodiment, the opening / closing plate 411 has a quadrant arc shape, and the cover chamber 410 may be formed into a cylindrical shape by combining four opening / closing plates 411. A hinge portion 413 coupled to a hinge shaft 416 may be formed on one side of the opening / closing plate 411. A wing portion 419 contacting the outer surface of the adjacent hinge shaft 416 may be integrally formed on the other side of the opening / closing plate 411.

[0047] The cover chamber 410 is configured in a cylindrical (drum) shape by connecting a plurality of opening and closing plates 411 to each other, and each opening and closing plate 411 is connected between opposing support disks 415 so as to be rotatable about a hinge shaft 416 .

[0048] A unit opening / closing plate 411 constituting the cylindrical lid chamber 410 is subjected to an elastic force in the direction of opening by a torsion spring 414. The opening / closing plate 411 is coupled to the hinge shaft 416 so that an elastic force is applied in the direction of opening by the torsion spring 414 disposed on the hinge shaft 416, but a plurality of guide rollers 417 fixed to the bracket 300 may come into contact with the door 200 at positions other than the upper side thereof to prevent the door 200 from opening or closing.

[0049] 9 and 11 show a state in which a plurality of guide rollers 417 fixed to the bracket 300 are arranged around the lid chamber 410. As shown in the drawings, a plurality of guide rollers 417 are arranged around both sides and the bottom of the lid chamber 410, excluding the top. Therefore, when the opening / closing plate 411 is positioned at the top during the process of rotating the lid chamber 410 by the power of the drive motor M, the upper opening / closing plate 411 is automatically opened (opened) by the elastic force of the torsion spring 414 since no guide rollers 417 are arranged around it (FIG. 11). Then, as the lid chamber 410 is further rotated, the opened upper opening / closing plate 411 is pressed by the guide rollers 417 and closed (closed).

[0050] In addition, the support disk 415 may have locking grooves 415a formed in multiple stages and spaced apart from one another in a circular pattern so that the elastic force can be adjusted according to the locking position of the end of the torsion spring 414. Therefore, when assembling the opening / closing plate 411 or after prolonged use, if the elastic force of the torsion spring 414 decreases and smooth opening and closing operations are impaired, the magnitude of the elastic force can be adjusted by changing the locking position of the end of the torsion spring 414 to an appropriate position in the multi-staged locking grooves 415a.

[0051] A tumbler lid is inserted into the lid chamber 410. At this time, washing water and rinsing water are sprayed at a predetermined pressure through nozzles 500 disposed at the top and bottom of the housing 100, thereby performing washing and rinsing (FIG. 14). The washing water and rinsing water can flow into the lid chamber 410 through a plurality of openings 412 formed in the opening / closing plate 411. The washing water and rinsing water sprayed from the nozzles 500 are collected at the bottom of the housing 100 and are discharged to the outside through the drain pipe 120.

[0052] A cup mounting stand 420 is disposed on one side of the lid chamber 410. The cup mounting stand 420 serves as a mounting stand for mounting a tumbler cup to be washed and rinsed, and may be attached to the bracket 300 so as to rotate together with the door 200 when it is opened, just like the lid chamber 410.

[0053] Cup mounting base 420 includes a cone-shaped mounting member 421 with a narrower diameter at the top end than at the bottom end. Cup mounting base 420 can be arranged to be rotatable vertically on a support 423 attached to bracket 300. Support 423 is formed by combining a horizontal plate and a vertical plate in a " " shape, for example. Cup mounting base 420 can be arranged vertically on the horizontal plate.

[0054] In addition, a gear 424 may be formed around the lower outer periphery of the cup setting stand 420. Specifically, the gear 424 may be formed around the lower outer periphery of the mounting member 421, and a plurality of drainage holes 422 may be formed in the mounting member 421. The drainage holes 422 are for smooth drainage and removal of residual water. In addition, a seating protrusion 425 may be formed on the outer inclined surface of the mounting member 421 in the inclined direction, so that a separation space may be formed between the inclined surface and the inner surface of the tumbler cup to be seated. A plurality of seating protrusions 425 may be formed along the inclined surface.

[0055] The power transmission means 600 may include a first pulley 610 coupled to one side of the cover chamber 410, a second pulley 620 arranged on one side of the cup mounting stand 420 so as to be rotatable about an axis perpendicular to the rotation direction of the cup mounting stand 420, and having teeth 621 formed on its outer surface to be gear-coupled with the gear 424, and a belt 630 connected to the first pulley 610 and the second pulley 620, respectively, to transmit power.

[0056] In another embodiment, the mounting member may be formed to have steps like stairs.

[0057] Therefore, cups manufactured in various sizes and shapes by the manufacturer can be fitted into the conical mounting member 421 and secured, and cleaning and rinsing can be performed through multiple nozzles 500 installed on the top and bottom of the housing 100.

[0058] Cup setting stand 420 may further include a support rod 426 coupled to the center of the top of mounting member 421, and a cup holder 427 coupled to the upper end of support rod 426. When washing water and rinsing water are sprayed at high pressure from nozzles 500 arranged around cup holder 420 with the cups seated in a cross shape, cup holder 427 can prevent the cups from shaking violently or coming off mounting member 421 due to the water pressure.

[0059] Washing water is supplied from a container 4 containing a cleaning solution through a supply pipe 6 via a pump 5, and rinsing water is sprayed through a nozzle 500 at a constant water pressure via the pump and supply pipe 6 while being directly connected to a water supply or stored in a separate rinsing water container. The washing and rinsing effects are enhanced when hot water is used for the washing water and rinsing water. Meanwhile, the area around the cup holder 420 is the area that the user mainly comes into contact with when consuming beverages, and therefore requires particularly thorough cleaning compared to other areas.

[0060] Therefore, nozzles 500 for spraying cleaning liquid and rinsing water in a diagonal direction (oblique direction) intersecting each other may be further disposed around the inlet of the cup placed on the cup placing stand 420. The rotational force of the driving motor M is transmitted to the power transmission means 600 to rotate the cup placing stand 420 at a constant speed, thereby evenly cleaning foreign matter that may be attached around the cup (FIGS. 12 and 13).

[0061] The second pulley 620 has teeth 621 that are coupled with a gear 424 formed around the cup mounting stand 420, and when the cover chamber 410 is rotated by the drive motor M, the teeth 621 of the second pulley 620 are rotated while meshing with the gear 424 of the cup mounting stand 420 through the power transmission means 600, thereby rotating the cup mounting stand 420 at a constant speed.

[0062] After the washing and rinsing process is completed for the cups, lids, and straws attached to the washing unit 400, it is preferable to further perform a residual water removal process in which the drive motor M is further operated for a certain period of time to rotate the lid chamber 410 and the cup mounting stand 420 at a certain speed, thereby shaking off and removing the water adhering around the cups and lids.

[0063] Therefore, even in the case of a product in which a recessed groove is formed in the cup, the residual water removal process and the structure in which the nozzles 500 spray in mutually intersecting directions will leave almost no residual water, so the cup can be immediately used as a container for putting drinking water in.

[0064] Meanwhile, a sterilization lamp L, consisting of ultraviolet light or an LED, for sterilizing the cups, lids, and straws during the washing and rinsing process may be further installed inside the housing 100. The sterilization lamp L is turned on while the cups, lids, and straws are washed and rinsed through the nozzle 500 with the opening of the housing 100 sealed by the door 200, thereby sterilizing them. In addition, the sterilization lamp L can be turned off by short-circuiting the switch when the door 200 is opened to replace the tumbler after the washing and rinsing are completed.

[0065] At least one housing 100 may be installed in a cabinet-structured multi-layer frame 1. A sink bowl 2 may be further installed on one side of the frame 1 for disposing of contents remaining in the cup or washing hands.

[0066] In the present invention, when the door 200 is opened, the lid chamber 410, the cup mounting base 420, and the straw insertion coil spring 430 are all rotated in the opening direction, allowing for replacement or installation of the tumbler, and the moment the door 200 is closed, a sensor or switch automatically performs cleaning, rinsing, sterilization, and draining of residual water, all in a rapid and stepwise manner.

[0067] Therefore, the cup, lid, and straw can all be automatically cleaned just before the user pours in drinking water, ensuring that drinking water is always in a clean and hygienic state.

[0068] Meanwhile, it is preferable that water trays are installed below the lid chamber 410, the cup mounting stand 420, and the straw insertion coil spring 430 of the cleaning unit 400 to prevent water from falling.

[0069] As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only for the purpose of explaining the invention, and a person having ordinary knowledge in the technical field to which the present invention belongs can make various modifications or equivalent embodiments from the detailed description of the invention.
