[0003] The Chinese patent application with application publication number CN109717804A, "A residue collecting structure for a cleaning machine and a cleaning machine using the residue collecting structure" (application number: CN201711052154.5), discloses a structure including a residue collecting portion arranged at the bottom of a water tank, the residue collecting portion having a residue filter cylinder for filtering and collecting residue, a residue separation unit for separating residue is arranged in the residue filter cylinder, the residue separation unit includes a residue guide cylinder located in the residue filter cylinder, the residue guide cylinder is open at both upper and lower ends, a gap is left between its bottom and the bottom wall of the residue filter cylinder, and the bottom periphery of the residue guide cylinder or the outer wall adjacent to its bottom has a convex edge extending outward, and there is a gap between the outer periphery of the convex edge and the peripheral wall of the residue filter cylinder.

[0004] Although the above structure improves the slag collection structure and improves the slag collection effect to a certain extent, it is limited by the shape of the water return area and the position at the bottom of the box, resulting in a large amount of water consumption per cleaning by the cleaning machine, which also affects the water return efficiency and cleaning effect.

[0005] Therefore, for current cleaning machines, further improvements need to be made. Summary of the invention

[0009] Preferably, the mounting plate is a metal part, the drain pipe is a plastic part, and an annular metal plate is sleeved on the outer periphery of the drain pipe, the metal plate is against the support plate, and screws pass through the support plate, the metal plate, and the positioning column to lock and connect the three. Since the mounting plate is made of metal parts and the drain pipe is made of plastic parts, the heat generated by the heating element installed at the bottom of the metal mounting plate when heated may cause damage to the support plate and the drain pipe. The above-mentioned metal plate is provided to disperse the relatively concentrated heat on the positioning column to the metal plate, reduce the heat concentration, and thus reduce the heat directly contacting the support plate and the drain pipe part, so as to avoid high-temperature deformation of the drain pipe and the support plate and protect them.

[0010] Further preferably, the outer edge of the metal plate is provided with a second edge extending vertically upward, and the second edge is arranged corresponding to the outer edge of the heating element. The metal plate and the heating element are enclosed above to form a heat preservation cavity for reducing heat loss of the heating element, and the side of the heat preservation cavity is open and communicated with the outside air. The above structure can prevent heat loss at the bottom of the heating element to improve heating efficiency, and the heat preservation cavity can also protect the heating element.

[0011] Preferably, a second sealing pad is sandwiched between the metal plate and the support plate. This structure can provide a buffer, so that the connection between the positioning column and the support plate is always locked when switching between high temperature and low temperature, thereby improving assembly compactness and reliability.

[0012] Preferably, the inner edge of the metal plate is provided with a first peripheral edge extending vertically upward, and the first peripheral edge is arranged close to the outer peripheral wall of the drain pipe. This structure further protects the drain pipe part inside the heating element to prevent it from being deformed by heat.

[0013] Preferably, the lower surface of the mounting plate is formed with an assembly edge extending downward along the drain outlet, the outer periphery of the assembly edge is sleeved with a first sealing ring tightly attached to the bottom wall of the mounting plate, and the upper end of the drain pipe is sleeved outside the assembly edge and the upper end is against the first sealing ring. This structure is conducive to improving the sealing performance of the drain outlet.

[0014] In order to facilitate installation, a mounting ring extending downward along the edge of the mounting opening is provided at the bottom of the box body, and a main body with an inverted U-shaped cross section is formed in the middle of the mounting plate, which is plugged and connected with the mounting ring.

[0015] Preferably, the assembly ring gradually extends outward in the radial direction from top to bottom. When the assembly is completed, the closed end edge of the U-shaped structure of the mounting plate is close to the upper edge of the assembly ring, and a triangular assembly gap is formed between the outer wall of the vertical part of the U-shaped structure and the inner wall of the assembly ring. A first sealing gasket that matches its shape is arranged in the assembly gap. This structure is conducive to improving the sealing performance at the mounting port.

[0016] Preferably, the mounting plate is provided with a support edge extending radially outward from the edge of the opening end of the U-shaped structure, the cross section of the first sealing gasket is an L-shaped structure, the vertical portion of the L-shaped structure is inserted into the assembly gap, the transverse portion of the L-shaped structure is supported on the support edge, and the outer periphery of the assembly ring is also sleeved with a locking sleeve, the bottom edge of the locking sleeve is pressed against the transverse portion of the L-shaped structure and is locked and connected with the support edge. With such a structure, under the extrusion of the assembly ring, the vertical portion of the L-shaped structure tends to be extruded from bottom to top into the assembly gap to improve the sealing performance.

[0017] Preferably, the upper part of the locking sleeve is formed into a conical sleeve structure with a small upper end and a large lower end that matches the shape of the assembly ring, and the lower part of the locking sleeve is provided with a clamping edge that extends radially outward and presses against the transverse part of the L-shaped structure, and the clamping edge is connected to the supporting edge screw. This structure is conducive to improving assembly reliability and sealing.

[0018] A cleaning machine comprises a water pumping mechanism, a slag collecting basket and the above-mentioned integrated mounting structure, wherein a concave water return area is arranged at the bottom of the box body, and the top of the water return area is covered with a filter plate, the water pumping mechanism and the slag collecting basket are arranged in the water return area, the water pumping mechanism is used to pump water in the water return area to above the filter plate, the slag collecting basket is arranged in the water return area and has a slag collecting port exposed from the filter plate and a drainage part arranged through the drainage port.

[0019] In the present invention, the bottom of the box is square, the return water area is elliptical and arranged along the diagonal of the box, the first end of the return water area is arranged near the first corner of the box, and the second end is arranged corresponding to the middle of the box, the pump mechanism is close to the second end of the return water area and arranged in the center relative to the bottom of the box, and the slag collection basket is located between the pump mechanism and the first corner of the box. In the prior art, due to the limitations of the shape of the return water area and the position of the bottom of the box, the cleaning machine consumes a lot of water for a single cleaning, which also affects the return water efficiency and cleaning effect. The elliptical return water area of ​​the present invention is arranged along the diagonal of the box and offset at a corner of the box, so that the pump mechanism is installed in the center relative to the box by using the second end of the elliptical return water area, and the slag collection basket can be arranged closer to the pump mechanism. Such an arrangement greatly reduces the overall volume of the return water area, thereby reducing the water consumption of a single cleaning, which can not only effectively improve the return water effect and the cleaning effect, but also save the space at the bottom of the box for installing other functional components, thereby improving space utilization.

[0020] Preferably, the length of the diagonal line of the bottom of the box is L1, and the distance between the two vertices of the elliptical water return area in the direction of its major axis is L2, L2 = (0.52 ~ 0.65) L1. More preferably, the distance between the two vertices of the elliptical water return area in the direction of its minor axis is L3, L3 = (0.6 ~ 0.75) L2. The above structure makes the arrangement of the water return area relative to the bottom of the box more reasonable, while reducing the volume of the water return area, improving the water return effect and reducing energy consumption.

[0021] Preferably, the water pump mechanism includes a pump housing, an impeller, a spray arm and a motor. The pump housing is arranged in the water return area and has a water inlet at the bottom and a water outlet at the top. The top of the pump housing is exposed above the filter plate. The spray arm is arranged above the filter plate and the water inlet is connected to the water outlet of the pump housing. The impeller is rotatably arranged in the pump housing. The motor is arranged at the outer bottom of the box body and the output shaft passes through the bottom wall of the box body and the water inlet is connected to the impeller. This structure facilitates pumping water from the water return area to the filter plate and washing the tableware by spraying water upward.

[0022] Preferably, the bottom wall of the box corresponding to the water return area has an upwardly protruding installation step, the installation step is provided with a motor installation port, and the top of the motor is provided with an upper cover plugged with the installation port, the upper cover is arranged corresponding to the water suction port of the pump housing and a water suction gap is formed between the two. The above structure is not only convenient for installing the motor, but also reduces the height of the water suction gap, and on the basis of ensuring high water absorption efficiency, avoids gas from being sucked in, so as to increase the water flow pressure and lift.

[0023] Preferably, a concave slag collecting area is provided at the bottom of the water return area, the edge of which is arranged close to the edge of the installation step, a drainage port is provided at the bottom of the slag collecting area, and the lower end of the slag collecting basket is plugged and connected with the drainage port. With the above structure, the raised installation step cooperates with the lowered slag collecting area, which is conducive to improving the water return efficiency; at the same time, the slag collecting area is located at the lowest point of the water return area, which is conducive to improving the drainage efficiency and achieving no residual water in the water return area.

[0024] Compared with the prior art, the advantages of the present invention are: the present invention integrates the heating element and the drainage assembly together, and only needs to open an installation port at the bottom of the box to assemble the integrated whole. It is not only convenient to assemble, but also the arrangement of functional components is more reasonable, which greatly improves the utilization rate of the bottom space of the box, makes the bottom of the return water area smoother, which is beneficial to improving the return water efficiency and heating efficiency, and avoids the accumulation of fine residues.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 6 As shown, the integrated installation structure of the cleaning machine of this embodiment includes a box body 1, a heating element 4 and a drainage assembly 5. A concave water return area 11 is provided at the bottom of the box body 1, and a filter plate 12 is covered on the top of the water return area 11.

[0033] The heating element 4 and the drainage component 5 are integrated on a mounting plate 6 to form an integrated whole A. A mounting opening 10 is provided at the bottom of the return water area 11. The mounting plate 6 can detachably cover the mounting opening 10. The heating element 4 and the drainage component 5 are both connected to the lower surface of the mounting plate 6. A drainage port 61 is provided on the mounting plate 6 to connect the return water area 11 with the drainage component 5.

[0034] Specifically, the drain port 61 is opened in the central part of the mounting plate 6, the heating element 4 is annular and arranged around the periphery of the drain port 61, and the drain assembly 5 includes a drain pipe 50 arranged under the mounting plate 6 and connected to the drain port 61. This structure makes the integrated structure of the heating element 4 and the drain assembly 5 more reasonable to save assembly space, and since the lower end of the slag collecting basket 3 is arranged corresponding to the drain port 61, during the water return process, most of the return water flows into the return water area 11 through the slag collecting basket 3, and the annular heating element 4 arranged around the drain port 61 can not only greatly improve the heating efficiency, but also disinfect the slag collecting basket 3.

[0035] The heating element 4 is welded to the mounting plate 6, and a positioning column 41 extending downward is provided on the lower surface of the heating element 4. Accordingly, a supporting plate 52 is provided on the outer peripheral wall of the drain pipe 50, and the positioning column 41 is detachably locked and connected to the supporting plate 52. This structure facilitates the integration of the drain pipe 50 and the mounting plate 6.

[0036] The mounting plate 6 of this embodiment is a metal part, and the drain pipe 50 is a plastic part. An annular metal plate 7 is sleeved on the outer periphery of the drain pipe 50, and the metal plate 7 is against the support plate 52. The screws pass through the support plate 52, the metal plate 7, and the positioning column 41 to lock and connect the three. Since the mounting plate 6 is made of metal parts and the drain pipe 50 is made of plastic parts, the heat generated by the heating element 4 installed at the bottom of the metal mounting plate 6 when heated may cause damage to the support plate 52 and the drain pipe 50. The above-mentioned metal plate 7 is provided to disperse the relatively concentrated heat on the positioning column 41 on the metal plate 7, reduce the heat concentration, and thus reduce the heat that is in direct contact with the support plate 52 and the drain pipe 50, so as to avoid high-temperature deformation of the drain pipe 50 and the support plate 52 and protect them. The outer edge of the metal plate 7 is provided with a second peripheral edge 72 extending vertically upward, and the second peripheral edge 72 is arranged corresponding to the outer edge of the heating element 4. The upper part of the metal plate 7 and the lower part of the heating element 4 enclose a heat preservation cavity 40 for reducing the heat loss of the heating element 4. The side of the heat preservation cavity 40 is open and communicated with the outside air. With the above structure, the heat loss at the bottom of the heating element 4 can be prevented to improve the heating efficiency. At the same time, the heat preservation cavity 40 can also protect the heating element 4.

[0037] A second sealing gasket 300 is also sandwiched between the metal plate 7 and the support plate 52. This structure can provide a buffer, so that the connection between the positioning column 41 and the support plate 52 is always locked when switching between high temperature and low temperature, thereby improving the compactness and reliability of assembly. The inner edge of the metal plate 7 is provided with a first peripheral edge 71 extending vertically upward, and the first peripheral edge 71 is arranged close to the outer peripheral wall of the drain pipe 50. This structure further protects the drain pipe part inside the heating element 4 to prevent it from being deformed by heat.

[0038] The lower surface of the mounting plate 6 is formed with a mounting edge 62 extending downward along the drain port 61, and the outer periphery of the mounting edge 62 is sleeved with a first sealing ring 100 that is tightly attached to the bottom wall of the mounting plate 6, and the upper end of the drain pipe 50 is sleeved outside the mounting edge 62 and the upper end is against the first sealing ring 100. This structure is conducive to improving the sealing performance of the drain port.

[0039] For ease of installation, a mounting ring 101 extending downward along the edge of the mounting opening 10 is provided at the bottom of the box body 1 , and a main body with an inverted U-shaped cross section is formed in the middle of the mounting plate 6 , which is plugged and connected to the mounting ring 101 .

[0040] The assembly ring 101 gradually extends outward in the radial direction from top to bottom. When the assembly is completed, the closed end edge of the U-shaped structure of the mounting plate 6 is close to the upper edge of the assembly ring 101, and a triangular assembly gap 102 is formed between the outer wall of the vertical part of the U-shaped structure and the inner wall of the assembly ring 101. A first sealing gasket 200 matching its shape is arranged in the assembly gap 102. This structure is conducive to improving the sealing performance at the mounting port.

[0041] The mounting plate 6 is provided with a support edge 63 extending radially outward from the edge of the opening end of the U-shaped structure. The cross section of the first sealing gasket 200 is an L-shaped structure. The vertical portion 201 of the L-shaped structure is inserted into the assembly gap 102. The transverse portion 202 of the L-shaped structure is supported on the support edge 63. The outer periphery of the assembly ring 101 is also sleeved with a locking sleeve 103. The bottom edge of the locking sleeve 103 presses against the transverse portion of the L-shaped structure and is locked and connected with the support edge 63. With such a structure, under the extrusion of the assembly ring 101, the vertical portion of the L-shaped structure tends to be extruded from bottom to top into the assembly gap 102 to improve the sealing performance.

[0042] The upper part of the locking sleeve 103 is formed into a tapered sleeve structure 1031 with a small upper end and a large lower end that matches the shape of the assembly ring 101. The lower part of the locking sleeve 103 is provided with a pressing edge 1032 that extends radially outward and presses against the transverse part of the L-shaped structure. The pressing edge 1032 is screwed to the supporting edge 63. This structure is conducive to improving assembly reliability and sealing.

[0043] The cleaning machine of this embodiment includes a water pumping mechanism 2, a slag collecting basket 3 and the above-mentioned integrated installation structure. The water pumping mechanism 2 and the slag collecting basket 3 are arranged in the return water area 11. The water pumping mechanism 2 is used to pump water in the return water area 11 to above the filter plate 12. The slag collecting basket 3 is arranged in the return water area 11 and has a slag collecting port 31 exposed from the filter plate 12 and a drainage part 32 arranged through the drainage port 61.

[0044] In this embodiment, the bottom of the box body 1 is square, the return water area 11 is elliptical and arranged along the diagonal of the box body 1, the first end of the return water area 11 is arranged near the first corner 1a of the box body 1, and the second end is arranged corresponding to the middle of the box body 1, that is, there is a large distance between the second end of the return water area 11 and the second corner 1b of the box body 1 arranged opposite to the first corner 1a. The water pumping mechanism 2 is arranged near the second end of the return water area 11 and centered relative to the bottom of the box body 1, and the slag collecting basket 3 is located between the water pumping mechanism 2 and the first corner 1a of the box body 1.

[0045] The length of the diagonal line at the bottom of the box 1 is L1, and the distance between the two vertices of the elliptical water return area 11 in the direction of its long axis is L2, L2 = (0.52 ~ 0.65) L1. The distance between the two vertices of the elliptical water return area 11 in the direction of its short axis is L3, L3 = (0.6 ~ 0.75) L2. The above structure makes the arrangement of the water return area 11 relative to the bottom of the box 1 more reasonable, while reducing the volume of the water return area 11, improving the water return effect and reducing energy consumption.

[0046] The water pump mechanism 2 includes a pump housing 21, an impeller 22, a spray arm 23 and a motor 24. The pump housing 21 is arranged in the water return area 11 and has a water suction port 211 at the bottom and a water outlet 212 at the top. The top of the pump housing 21 is exposed above the filter plate 12. The spray arm 23 is arranged above the filter plate 12 and the water inlet is connected to the water outlet 212 of the pump housing 21. The impeller 22 is rotatably arranged in the pump housing 21. The motor 24 is arranged at the outer bottom of the box body 1 and the output shaft passes through the bottom wall of the box body 1 and is connected to the water suction port 211 and the impeller 22. This structure facilitates the water pump from the water return area 11 to the filter plate 12, and the tableware is rinsed by spraying water upward.

[0047] The bottom wall of the box body 1 corresponding to the return water area 11 has an upwardly protruding installation step 13, and a motor installation port 131 is opened on the installation step 13. The top of the motor 24 is provided with an upper cover 241 that is plugged into the installation port 131. The upper cover 241 is arranged corresponding to the water suction port 211 of the pump housing 21 and a water suction gap 001 is formed between the two. The above structure is not only convenient for installing the motor 24, but also reduces the height of the water suction gap 100, and on the basis of ensuring high water suction efficiency, it prevents gas from being sucked in, so as to increase the water flow pressure and lift.

[0048] A concave slag collecting area 14 is provided at the bottom of the water return area 11, the edge of which is arranged close to the edge of the mounting step 13, a drainage port 15 is provided at the bottom of the slag collecting area 14, and the lower end of the slag collecting basket 3 is plugged and connected with the drainage port 15. With the above structure, the raised mounting step 13 cooperates with the lowered slag collecting area 14, which is conducive to improving the water return efficiency; at the same time, the slag collecting area 14 is located at the lowest point of the water return area 11, which is conducive to improving the drainage efficiency and achieving no residual water in the water return area 11.

[0049] The present embodiment integrates the heating element 4 and the drainage assembly 5 together, and only needs to open an installation opening 10 at the bottom of the box body 1 to assemble the integrated whole. It is not only convenient to assemble, but also more reasonable to arrange the functional components, greatly improving the utilization rate of the bottom space of the box body, making the bottom of the return water area more flat, which is beneficial to improving the return water efficiency and heating efficiency, and avoiding the accumulation of fine residues; an elliptical return water area 11 structure adapted to the square box body 1 is designed, and the elliptical return water area 11 is arranged along the diagonal of the box body 1 and offset at a corner of the box body 1, so that the water pumping mechanism 2 is installed in the center relative to the box body 1 by using the second end of the elliptical return water area 11, and the slag collecting basket 3 is arranged closer to the water pumping mechanism 2. Such an arrangement method greatly reduces the overall volume of the return water area 11, thereby reducing the water consumption of a single cleaning, which can not only effectively improve the return water effect and the cleaning effect, but also save the bottom space of the box body 1 for installing other functional components, thereby improving the space utilization rate. Compared with the existing water return area structure and the corresponding water pump mechanism installation method, the structure of this embodiment reduces the volume of the water return area by about 40% and the water consumption for a single cleaning by about 20%.
