Description

Technical Field

[0001] The invention relates to a cleaning machine. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Currently, dishwashers 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] In order to avoid abnormal water inflow problems, it is usually necessary to set an overflow protection device on the cleaning machine. For example, the Chinese patent "Ventilation, overflow protection and cleaning agent addition device for sink type cleaning machine" (application number: CN201410851060.4) with authorization announcement number CN104545751B of the applicant integrates the ventilation, overflow protection and cleaning agent addition structures into one in order to save space; the Chinese patent application "A ventilation, overflow and water inlet integrated structure" (application number: CN201610622462.6) with application publication number CN106088263A of the applicant integrates the ventilation, overflow and water inlet structures into one in order to facilitate the discharge of moisture. Although the above structures effectively save assembly space and simplify the production process of the overall components, after integration, the various functions are easily affected by each other due to the relatively concentrated structure. Since the overflow structure is usually connected to the external drainage, and the external drainage pipe is connected to an odor-proof basket or S-shaped bend for odor prevention, there must be a space between the overflow structure and the drainage pump. The presence of this air section can easily affect the realization of the overflow function, which in turn affects the ventilation and other functions, affecting the normal use of the cleaning machine. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cleaning machine capable of timely discharging the air between the overflow structure and the drainage pump to ensure the normal use of the overflow and ventilation functions in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, comprising a box body with a washing chamber, a water inlet connected to the washing chamber is opened on the side wall of the box body, and a drain outlet is provided at the bottom of the box body, and a drain pump and a first drain pipe are connected to the drain outlet. It is characterized in that: an independently arranged water inlet and air permeable component and an independently arranged overflow component are provided on the side wall of the box body, the water inlet and air permeable component has a water inlet port and an air permeable port connected to the water inlet, the water inlet end and the water outlet end of the overflow component are both located below the lower edge of the water inlet, and the liquid level corresponding to the middle part of the overflow component is located between the upper edge and the lower edge of the water inlet.

[0006] In the above solution, the overflow assembly includes an overflow pipe formed into an inverted U-shaped structure, and the overflow pipe has a first port connected to the water outlet end of the first drainage pipe and a second port connected to the water inlet end of the second drainage pipe. The first port and the second port are arranged lower than the water inlet, which is conducive to not affecting the realization of water inlet and ventilation functions when the overflow assembly is started.

[0007] Preferably, the upper wall of the top of the overflow pipe is arranged horizontally to form a first horizontal wall surface, and the two ends of the first horizontal wall surface gradually extend outward from top to bottom to form a first inclined wall surface and a second inclined wall surface, and according to the direction of water flow, the first inclined wall surface is located downstream of the second inclined wall surface, and the slope of the first inclined wall surface is smaller than the slope of the second inclined wall surface, and the lower end of the first inclined wall surface is higher than the lower end of the second inclined wall surface. This structure is conducive to the smooth discharge of water flow during the overflow process.

[0008] Preferably, the lower wall at the top of the overflow pipe is arranged horizontally to form a second horizontal wall surface, and the two ends of the second horizontal wall surface gradually extend outward from top to bottom to form a third inclined wall surface and a fourth inclined wall surface. According to the direction of water flow, the third inclined wall surface is located downstream of the fourth inclined wall surface, and the lower end of the third inclined wall surface is higher than the lower end of the fourth inclined wall surface. The second horizontal wall surface and the third inclined wall surface and the fourth inclined wall surface are all smoothly transitioned. This structure is conducive to the smooth discharge of water during the overflow process.

[0009] In the above schemes, the height of the second horizontal wall is between the upper edge and the lower edge of the water inlet. The height of the first horizontal wall is not higher than the height of the upper edge of the water inlet. The above structure can not only store enough water in the washing chamber to meet the cleaning needs, but also avoid the blockage of the exhaust port, which is conducive to the discharge of water when overflowing.

[0010] As an improvement, the top of the overflow pipe extends upward to form an exhaust port that connects the overflow pipe to the outside atmosphere, and the exhaust port is provided with a floating component that can open the exhaust port when the liquid level is lower than the upper wall of the overflow pipe, and close the exhaust port when the liquid level is higher than the upper wall of the overflow pipe. Such a structure is conducive to quickly discharging the air between the overflow pipe and the drainage pump, avoiding malfunction of the overflow component due to air resistance.

[0011] Preferably, the floating assembly includes a mounting frame and a floating member, the mounting frame is arranged outside the overflow pipe and has a connecting column that can extend into the exhaust port from top to bottom, a gap is formed between the connecting column and the inner wall of the exhaust port, and the floating member is arranged on the connecting column so as to be movable up and down, the floating member moves downward to open the gap, and the floating member moves upward to close the gap. When the overflow water in the washing chamber enters the overflow pipe from the first drainage pipe on one side of the drainage pump, the floating member is in a falling state because it does not touch the water surface, the exhaust port is open, and the air in the drainage pipe is gradually discharged from the exhaust port. When the overflow water level reaches the top of the overflow pipe, the floating member is given buoyancy, so that the floating member moves upward to close the exhaust port, and the overflow water continues to be discharged after passing through the top of the overflow pipe, while the exhaust port is closed by the floating member, and no leakage problem occurs.

[0012] To facilitate assembly, the mounting frame has a top plate suspended above the exhaust port, with support plates on both sides of the top plate for fixing it on the overflow pipe. The connecting column is arranged on the lower wall surface of the top plate, and the lower end of the connecting column has a limit block for preventing the floating part from detaching.

[0013] In order to improve the sealing performance, the inner diameter of the top of the exhaust port is reduced to form a contracted port, and a sealing ring arranged along the circumference and capable of cooperating and sealing with the floating member when the floating member moves upward is provided on the inner wall of the port.

[0014] Compared with the prior art, the advantages of the present invention are: the present invention independently arranges the water inlet and air permeable component and the overflow component, and the two do not interfere with each other, and the water inlet end and the water outlet end of the overflow component are both located below the lower edge of the water inlet, and the liquid level corresponding to the middle of the overflow component is located between the upper edge and the lower edge of the water inlet, so that the air between the overflow structure and the drainage pump can be discharged in time, so that the overflow and air permeability functions can always maintain normal use.

[0019] The present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, the cleaning machine of this embodiment includes a box body 1 with a washing chamber, a water inlet 11 connected to the washing chamber is opened on the side wall of the box body 1, a drain outlet 12 is provided at the bottom of the box body 1, a drain pump 13 and a first drain pipe 14 are connected to the drain outlet 12, an independently arranged water inlet and air permeable component 2 and an independently arranged overflow component 3 are provided on the side wall of the box body 1, the water inlet and air permeable component 2 has a water inlet port 21 and an air port 22 connected to the water inlet 11, the water inlet end 31 and the water outlet end 32 of the overflow component 3 are both located below the lower edge of the water inlet 11, and the liquid level corresponding to the middle of the overflow component 3 is located between the upper edge and the lower edge of the water inlet 11.

[0021] Specifically, the overflow assembly 3 includes an overflow pipe 30, which is formed into an inverted U-shaped structure. The overflow pipe 30 has a first port connected to the water outlet of the first drainage pipe 14 and a second port connected to the water inlet of the second drainage pipe, wherein the second drainage pipe is connected to the external sewage discharge main pipe, and an odor-proof S-bend pipe section can be provided on the second drainage pipe. The first port is the water inlet end 31, and the second port is the water outlet end 32. The first port and the second port are arranged lower than the water inlet 11, which is conducive to not affecting the realization of water inlet and ventilation functions when the overflow assembly 3 is started. The upper wall at the top of the overflow pipe 30 is arranged horizontally to form a first horizontal wall 301. The two ends of the first horizontal wall 301 extend gradually outward from top to bottom to form a first inclined wall 302 and a second inclined wall 303. According to the direction of water flow, the first inclined wall 301 is located downstream of the second inclined wall 302, and the slope of the first inclined wall 301 is smaller than the slope of the second inclined wall 302. The lower end of the first inclined wall 301 is higher than the lower end of the second inclined wall 302. This structure is conducive to the smooth discharge of water during the overflow process. The lower wall at the top of the overflow pipe 30 is arranged horizontally to form a second horizontal wall 304. The two ends of the second horizontal wall 304 extend gradually outward from top to bottom to form a third inclined wall 305 and a fourth inclined wall 306. According to the direction of water flow, the third inclined wall 305 is located downstream of the fourth inclined wall 306, and the lower end of the third inclined wall 305 is higher than the lower end of the fourth inclined wall 306. The second horizontal wall 304 and the third inclined wall 305 and the fourth inclined wall 306 are all in smooth transition. This structure is conducive to the smooth discharge of water during overflow. The height of the second horizontal wall 304 is located between the upper edge and the lower edge of the water inlet 11. The height of the first horizontal wall 301 is not higher than the height of the upper edge of the water inlet 11. The above structure can not only store enough water in the washing chamber to meet the cleaning needs, but also avoid the blockage of the air vent, which is conducive to the discharge of water during overflow.

[0022] In this embodiment, the top of the overflow pipe 30 extends upward to form an exhaust port 307 that connects the overflow pipe 30 with the outside atmosphere. The exhaust port 307 is provided with a floating assembly 5 that can open the exhaust port 307 when the liquid level is lower than the upper wall of the overflow pipe 30, and close the exhaust port 307 when the liquid level is higher than the upper wall of the overflow pipe 30. Such a structure is conducive to quickly discharging the air between the overflow pipe 30 and the drainage pump, and avoiding the failure of the overflow assembly 3 due to air resistance. The floating assembly 5 of this embodiment includes a mounting frame 51 and a floating member 52. The mounting frame 51 is arranged outside the overflow pipe 30 and has a connecting column 511 that can extend from top to bottom into the exhaust port 307. A gap 512 is formed between the connecting column 511 and the inner wall of the exhaust port 307. The floating member 52 is arranged on the connecting column 511 so as to be movable up and down. The floating member 52 moves downward to open the gap 512, and the floating member 52 moves upward to close the gap 512. In order to facilitate assembly, the mounting frame 51 has a top plate 513 suspended above the exhaust port 307, and the top plate 513 has support plates 514 on both sides that can be fixed to the overflow pipe 30 by screws. The connecting column 511 is arranged on the lower wall surface of the top plate 513, and the lower end of the connecting column 511 has a stopper 515 that can prevent the floating member 52 from detaching. In order to improve the sealing performance, the inner diameter of the top of the exhaust port 307 is reduced to form a contracted port, and the inner wall of the port is provided with a sealing ring 309 arranged along the circumferential direction and capable of cooperating with the floating member 52 to seal when the floating member 52 moves upward.

[0023] In this embodiment, the water inlet ventilation component 2 and the overflow component 3 are independently arranged, and the two do not interfere with each other, and the water inlet end 31 and the water outlet end 32 of the overflow component 3 are both located below the lower edge of the water inlet 11, and the liquid level corresponding to the middle of the overflow component 3 is located between the upper edge and the lower edge of the water inlet 11, so that the air between the overflow structure and the drainage pump can be discharged in time. At the same time, when the overflow occurs, the overflow water in the washing chamber enters the overflow pipe 30 from the first drainage pipe 14 on the side of the drainage pump 13. Since the floating member 52 is not in contact with the water surface and is in a falling state, the exhaust port 307 is open, and the air in the drainage pipe 30 is gradually discharged from the exhaust port 307 as the liquid level rises. When the overflow liquid level reaches the top of the overflow pipe 30, the floating member 52 is given buoyancy, so that the floating member 52 moves up to close the exhaust port 307. The overflow continues to be discharged after passing through the top of the overflow pipe 30, and the exhaust port 307 is closed by the floating member, so there will be no leakage problem, so that the overflow and ventilation functions can always maintain normal use.
