Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cleaning machine, and more particularly to a sink cleaning machine. Background Art

[0002] As people's living standards continue to improve, kitchen cleaning machines, such as dishwashers, as a kitchen appliance, are increasingly entering households. Currently, the cleaning machines on the market are generally divided into three types: desktop, cabinet, and tank. Among them, desktop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] The various forms of dishwashers mentioned above generally use a water pump to lift water and spray it onto the dishes in the cleaning space to achieve the cleaning effect. The box body of the washing chamber is provided with an overflow seat, which can be connected to an external water inlet pipe, and is also convenient for the overflow water to be discharged. For example, the Chinese utility model patent application with application number CN202022220774.9 (authorization announcement number: CN214760956U) discloses a cleaning machine, including a box body with a washing chamber, a water inlet is opened on the side wall of the box body, and a water inlet pipe connected to the water inlet is arranged on the outside of the box body, and an ultrasonic generator capable of generating bubbles in the inlet water is arranged in the water inlet pipe. The water inlet is located in the middle or upper part of the side wall of the box body and forms an overflow port. The outer side wall of the box body is provided with an overflow seat connected to the overflow port, and the overflow seat has a first opening connected to the output end of the water inlet pipe and a second opening for the overflow water to be discharged. The side wall of the overflow seat is provided with an opening corresponding to the overflow port, the overflow seat is hollow inside to form an overflow cavity, the first opening is provided on the bottom wall of the overflow seat and is connected with the water inlet and relatively isolated from the overflow cavity.

[0004] However, the washing machine in the above patent application still has certain shortcomings. The first opening on the overflow seat for water inlet is arranged on the bottom wall of the overflow seat, and the overflow port is located higher than the first opening. When the dishwasher is working normally, the water sprayed by the spray arm may splash into the overflow seat cavity, and the overflow water in the dishwasher continues to contact with the water source of the water inlet channel, which may cause water contamination.

[0005] Therefore, existing cleaning machines also need further improvement. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a cleaning machine which can effectively prevent the overflowing water in the washing chamber from contacting and being polluted by the inlet water source in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a cleaning machine, comprising:

[0008] A box body having a washing chamber, wherein a mounting opening communicating with the washing chamber is provided on a side wall of the box body;

[0009] a water inlet seat, mounted on the outer side wall of the box body and covering the mounting opening on the side wall of the box body, wherein the water inlet seat defines an overflow chamber with an open opening, a water inlet flow channel and an overflow flow channel, wherein the open opening of the overflow chamber is opposite to the mounting opening on the side wall of the box body, the overflow flow channel has an overflow port connected to the overflow chamber for discharging water in the washing chamber, and the water inlet flow channel has an inlet connected to the washing chamber for allowing external water to enter the washing chamber;

[0010] The water inlet of the water inlet flow channel is located at a position higher than the overflow port of the overflow flow channel.

[0011] The structural design that the water inlet of the water inlet channel is higher than the overflow port of the overflow channel can achieve the purpose of cutting off the connection between the washing chamber of the cleaning machine and the water inlet channel, effectively avoiding the contact and contamination of the overflow water in the washing chamber with the water source, and ensuring the cleanliness of the washing chamber.

[0012] Taking into account the amount of water in the washing chamber and the amount of overflow, the distance between the water inlet of the water inlet channel and the overflow of the overflow channel needs to be reasonably designed to ensure that the water overflowing from the washing chamber does not come into contact with the water source and is contaminated. The vertical distance between the lowest position of the water inlet of the water inlet channel and the lowest position of the overflow of the overflow channel is recorded as the first distance, and the value range of the first distance is: 2.5cm-5.5cm.

[0013] In order to simplify the structure of the water inlet seat, the overflow chamber includes left and right opposite side walls and a top wall connected between the left and right side walls. The overflow port is opened on the side wall of the overflow chamber, at least a section of the water inlet channel is formed on the top of the overflow chamber, and the water inlet is also adjacent to the top wall of the overflow chamber and faces the washing chamber.

[0014] In order to prevent the water inlet seat from protruding excessively outward from the side wall of the box body, occupying the installation space and affecting the aesthetics of the assembly, a downwardly arched enclosure extending in the front-to-back direction is provided on the top wall of the overflow chamber. The enclosure and the top wall of the overflow chamber define a section of the water inlet channel.

[0015] In order to be isolated from the overflow chamber, the end of the enclosure extends horizontally to the location of the installation opening of the box body, and forms the water inlet in the area defined by the outer peripheral edge of the installation opening.

[0016] In order to further rationally utilize the space in the overflow chamber of the water inlet seat and make the overall volume of the water inlet seat more compact, the main body of the water inlet seat is also provided with a vertically extending water inlet pipe, which extends from the bottom of the water inlet seat into the overflow chamber and is connected to the enclosure, and a water outlet is provided on the enclosure at a position corresponding to the upper end of the water inlet pipe.

[0017] In order to allow the water reaching the overflow port to be discharged smoothly through the overflow pipe, the main body of the water inlet seat is also provided with an overflow pipe, which is formed into an inverted L-shaped structure, and the end of the transverse part of the L-shaped overflow pipe is connected to the overflow port.

[0018] As an improvement, the overflow port is located higher than the bottom wall of the overflow chamber. When the cleaning machine is working normally, the water sprayed by the spray arm may splash into the overflow chamber of the water inlet seat. In order to prevent the water from flowing away from the overflow port and affecting the cleaning degree, the overflow surface of the overflow port (that is, the plane where the lowest position of the overflow port is located) is raised.

[0019] In order to conveniently install the water inlet seat on the side wall of the box body, a mounting plate covering the mounting opening is provided on the inner wall of the box body, and the outer peripheral edge of the mounting plate is limited inside the outer peripheral edge of the mounting opening of the box body. The mounting plate is partially deformed outward and protrudes through the mounting opening to be locked and connected with the water inlet seat.

[0020] In order to prevent the installation of the mounting plate from affecting the overflow process, an opening opposite to the opening of the overflow chamber is provided in the middle of the mounting plate.

[0021] In order to lock the water inlet seat and the mounting plate, the overflow chamber has a rear wall opposite to its opening and a support column extending forward from the rear wall. The outwardly protruding portion of the mounting plate abuts against the end of the support column and is connected by a connecting piece.

[0022] In order to prevent water from the washing chamber from splashing into the overflow chamber during normal operation of the cleaning machine, the machine also includes a decorative cover detachably connected to the mounting plate. The decorative cover covers the front side of the opening of the mounting plate, and the surrounding edges define a water gap with the main body of the mounting plate.

[0023] In order to simplify the connection structure between the decorative cover and the mounting plate, the decorative cover is provided with an outwardly extending plug at the outer peripheral edge, and the plug has a limit stop and a limit protrusion arranged in sequence along its length direction. A slot for the plug to be inserted into is correspondingly provided on the mounting plate. When the decorative cover is assembled in place on the mounting plate, the limit stop and the limit protrusion of the plug are respectively limited on the front and rear sides of the outer peripheral edge of the slot.

[0024] In order to prevent water from leaking or seeping out from the gap between the water inlet seat and the side wall of the box body and ensure the sealing effect, a sealing ring is provided between the water inlet seat and the outer peripheral edge of the installation opening on the side wall of the box body to seal with both.

[0025] Compared with the prior art, the advantages of the utility model are as follows: the structural design of the water inlet of the water inlet channel being higher than the overflow of the overflow channel can achieve the purpose of cutting off the connection between the washing chamber of the cleaning machine and the water inlet channel, effectively avoiding the contact and contamination of the overflow water in the washing chamber with the water inlet source, and ensuring the cleanliness of the washing chamber. In the preferred embodiment, considering that when the cleaning machine is working normally, the water sprayed by the spray arm may splash into the overflow chamber of the water inlet seat, the overflow surface of the overflow port (that is, the plane where the lowest position of the overflow port is located) is raised to prevent water from flowing away from the overflow port and thus affecting the cleaning degree.

For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0035] Figure 1-Figure 7 A preferred embodiment of the cleaning machine of the utility model is shown. A cleaning machine comprises a box 10 having a washing chamber 100, a spray arm rotatably arranged in the washing chamber 100, and a water inlet seat 20 arranged on the outer wall of the box 10. A water pumping mechanism for pumping water from the bottom of the box 10 to the spray arm is also provided at the bottom of the box 10. The water pumping mechanism and the spray arm are the same as those of the applicant's prior application 201320889945.4, and are not described in detail here.

[0036] See also Figure 3 The side wall of the box body 10 is provided with an installation opening 11 which is connected with the washing chamber 100. The water inlet seat 20 is installed on the outer side wall of the box body 10 and covers the installation opening 11 on the side wall of the box body 10. The water inlet seat 20 defines an overflow chamber 200 with an open opening, a water inlet channel 210 and an overflow channel 220.

[0037] A mounting plate 30 covering the mounting opening 11 is provided on the inner side wall of the box body 10. The mounting plate 30 can be connected to the water inlet seat 20, so that the water inlet seat 20 is locked and connected to the side wall of the box body 10. Specifically, the overall size of the mounting plate 30 is slightly larger than the mounting opening 11, wherein the outer peripheral edge of the mounting plate 30 can be limited to the inner side of the outer peripheral edge of the mounting opening 11 of the box body 10. The overflow chamber 200 has a rear wall opposite to its opening, two side walls opposite to the left and right, and a top and bottom wall opposite to the top and bottom. The rear wall of the overflow chamber 200 has a support column 23 extending forward, and the support column 23 has two support columns 23 arranged at intervals on the left and right. The local outward deformation of the mounting plate 30 protrudes through the mounting opening 11 and abuts against the ends of the two support columns 23 of the water inlet seat 20. A connecting hole 300 is opened at a position opposite to the two support columns 23 on the mounting plate 30, and a screw passes through the above-mentioned connecting hole 300 to connect with the ends of the support columns 23. After the screws are locked in place, the outer edge of the mounting plate 30 abuts against the inner side of the outer edge of the mounting opening 11 of the box body 10, and the main body of the water inlet seat 20 abuts against the inner side of the outer edge of the mounting opening 11 of the box body 10. After the water inlet seat 20 is installed in place, the opening of the overflow chamber 200 is opposite to the mounting opening 11 on the side wall of the box body 10, and a sealing ring 24 is provided between the outer periphery of the opening of the water inlet seat 20 and the outer periphery of the mounting opening 11 on the side wall of the box body 10 to seal the two. The sealing ring 24 can prevent water from leaking or seeping out from the gap between the water inlet seat 20 and the side wall of the box body 10, thereby ensuring the sealing effect. In order to prevent the installation of the mounting plate 30 from affecting the overflow process, an opening 31 opposite to the opening of the overflow chamber 200 is provided in the middle of the mounting plate 30, and the water in the washing chamber 100 can enter the overflow chamber 200 of the water inlet seat 20 through the opening 31 of the mounting plate 30.

[0038] The main body of the water inlet seat 20 also has a vertically extending water inlet pipe 21 and an inverted L-shaped overflow pipe 22. The water inlet pipe 21 and the overflow pipe 22 are designed as an integral part of the main body of the water inlet seat 20. The water inlet pipe 21 can be used to connect to an external water supply pipe. The overflow pipe 22 can be used to connect to an external wastewater discharge pipeline. More specifically, in order to further rationally utilize the space in the overflow chamber of the water inlet seat 20 and make the overall volume of the water inlet seat 20 more compact, the water inlet seat 20 is a flat structure as a whole, and the L-shaped overflow pipe 22 is located on the right side of the main body of the water inlet seat 20. The end of the transverse part of the L-shaped overflow pipe 22 passes through the right side wall of the overflow chamber, that is, the right side wall of the overflow chamber is provided with an overflow port 221 for the water supply flow to enter the overflow pipe 22. When the cleaning machine is working normally, the water sprayed by the spray arm may splash into the overflow chamber of the water inlet seat 20. In order to prevent the water from flowing away from the overflow port 221 and thus affecting the cleaning degree, the water inlet seat 20 of this embodiment adopts a design of raising the overflow surface of the overflow port 221 (that is, the plane where the lowest position of the overflow port 221 is located). Specifically, Figure 4As shown, the overflow port 221 is located higher than the bottom wall of the overflow chamber 200, and the distance between the lowest position of the overflow port 221 and the bottom wall of the overflow chamber is recorded as the second distance.

[0039] A downwardly arched enclosure 212 is provided on the top wall of the overflow chamber 200. The enclosure 212 extends in the front-to-back direction, and the front end portion extends forward to the position of the mounting port 11 of the housing 10, and forms a water inlet 211 connected to the washing chamber 100 in the area defined by the outer peripheral edge of the mounting port 11. The water inlet pipe 21 extends vertically, specifically, from the bottom of the water inlet seat 20 into the overflow chamber 200, and the top of the water inlet pipe 21 is connected to the enclosure 212, and a water outlet 2120 is correspondingly provided on the enclosure 212 at a position connected to the upper end of the water inlet pipe 21, thereby, the inner cavity of the water inlet pipe 21 and a section enclosed between the enclosure 212 and the top wall of the overflow chamber 200 together constitute the water inlet flow channel 210 of the water inlet seat 20. By offsetting the overflow pipe 22 to the side of the water inlet seat 20 body and vertically passing the water inlet pipe 21 into the overflow cavity, the water inlet seat 20 can be effectively prevented from excessively protruding outward from the side wall of the box body 10 and occupying the installation space, making the water inlet seat 20 more compact as a whole.

[0040] pass Figure 7 It can be seen that the position of the water inlet 211 of the water inlet channel 210 is higher than the position of the overflow port 221 of the overflow channel 220. Considering the amount of water in the washing chamber 100 and the amount of overflow, the distance between the water inlet 211 of the water inlet channel 210 and the overflow port 221 of the overflow channel 220 needs to be reasonably designed, so as to ensure that the overflowing water in the washing chamber does not contact and pollute the water source of the water inlet. The vertical distance between the lowest position of the water inlet 211 of the water inlet channel 210 and the lowest position of the overflow port 221 of the overflow channel 220 is recorded as the first distance L1, and the value range of the first distance L1 is: 2.5cm-5.5cm. The structural design that the water inlet 211 of the water inlet channel 210 is higher than the overflow port 221 of the overflow channel 220 can achieve the purpose of cutting off the connection between the washing chamber 100 of the cleaning machine and the water inlet channel 210, effectively avoiding the contact and contamination of the overflow water in the washing chamber with the water source, and ensuring the cleanliness of the washing chamber 100.

[0041] In order to prevent the water flow of the washing chamber 100 from splashing into the overflow chamber 200 during the normal operation of the cleaning machine, a decorative cover 40 is also connected to the mounting plate 30. The decorative cover 40 is square, and has plugs 41 extending outward at its four corners. Each plug 41 has a limit stop 411 and a limit protrusion 412 arranged in sequence along its length direction. The limit stop 411 is relatively close to the main body of the decorative cover 40, and the limit protrusion 412 is far away from the main body of the decorative cover 40. The mounting plate 30 is correspondingly provided with a slot 32 for the plug 41 to be inserted therein, and the slot 32 is a strip groove adapted to the plug 41. The limit protrusion 412 on the plug 41 is an arc-shaped protrusion protruding outward relative to the wall surface of the plug 41. The arc-shaped protrusion can pass through the slot 32 of the mounting plate 30 and extend into the overflow chamber 200 of the water inlet seat 20. When the decorative cover 40 is assembled on the mounting plate 30, the decorative cover 40 covers the front side of the opening 31 of the mounting plate 30, the limiting protrusion 412 on the inserting piece 41 is limited to the side of the outer peripheral edge of the slot 32 on the mounting plate 30 facing the overflow chamber 200, and the limiting stopper 411 of the inserting piece 41 is correspondingly limited to the side of the outer peripheral edge of the slot 32 on the mounting plate 30 away from the overflow chamber 200. The limiting stopper 411 of the inserting piece 41 is at a certain distance from the main body of the decorative cover 40, so that the four peripheral edges of the decorative cover 40 and the main body of the mounting plate 30 reserve space for the water flow in the washing chamber 100 to enter the water-passing gap 50 in the overflow chamber 200.
