In the above scheme, in order to adapt to the open water pump structure, the drain plate is arranged into three parts that can be spliced ​​with each other. The first part is very small in size, which is convenient for assembling it with the water supply pipe. The first part is constrained to the bottom of the box body by the water supply pipe when leaving the factory as a fixed part. The second and third parts cover the main range of the drain area. The second part is locked on the box body. When the drain area needs to be cleaned, only the third part needs to be removed, which is convenient to operate.

[0004] Although the above structure can remove the third part of the drain plate, the second part of the drain plate covers the water pump. If the water pump needs to be repaired, the second part also needs to be removed. The second part is locked to the bottom of the water cup by screws, and disassembly and assembly is very troublesome, which brings inconvenience to the maintenance of the functional parts of the water pump.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 6 As shown, the cleaning machine of this embodiment includes a box body 1 and a filter plate 2. A concave water return area 11 is provided at the bottom of the box body 1. The filter plate 2 covers the top of the water return area 11. A support 12 is formed on the outer periphery of the open top of the water return area 11. The edge of the filter plate 2 rests on the support 12. The lower surface of the filter plate 2 and the inner side wall of the water return area 11 are correspondingly provided with a snap structure that can detachably restrain the filter plate 2 at the bottom of the box body 1.

[0030] The relative support structure and snap-fit ​​structure between the support platform 12 and the edge of the filter plate 2 form an elastic positioning structure that can constrain the filter plate 2 at the bottom of the box body 1. This structure is conducive to improving the reliability and stability of the filter plate installation.

[0031] Specifically, the edge of the filter plate 2 is provided with a support edge 21 extending downward, and the support edge 21 abuts against the support platform 12. This structure is conducive to further improving the installation stability of the filter plate 2.

[0032] The outer edge of the support 12 is provided with an upwardly extending peripheral edge 13, and the supporting edge 21 is arranged close to the peripheral edge 13 with a sealing ring 3 sandwiched therebetween. This structure can improve the sealing performance between the filter plate 2 and the top edge of the return water area 11, and prevent residue from entering the return water area 11 without being filtered.

[0033] The lower surface of the filter plate 2 is provided with a buckle 22 extending downward, and correspondingly, the inner side wall of the water return area 11 is provided with a slot 14 arranged near its top edge, and the buckle 22 is detachably connected with the slot 14. This structure facilitates the detachable connection between the lower surface of the filter plate 2 and the inner side wall of the water return area.

[0034] The buckle 22 includes a connecting arm 221 extending upward and downward and a clamping foot 222 bent outward from the lower end of the connecting arm 221. A limiting rib 141 is formed in the middle of the clamping slot 14 to be clamped and limited with the upper edge of the clamping foot 222. This structure is conducive to improving the clamping and limiting stability of the filter plate 2.

[0035] The slot 14 extends downward from the top edge of the water return area 11 to form a notch 142 for the pin 222 to be inserted into. The inner wall surface of the lower part of the slot 14 forms an inclined surface 143 that gradually tilts outward from bottom to top. The upper edge of the inclined surface 143 and the lower edge of the notch 142 form a limiting rib 141. The above structure facilitates the buckle 22 of the filter plate 2 to be buckled into the slot 14 during installation, and improves the limiting stability after buckling.

[0036] The lower part of the connecting arm 221 gradually tilts from top to bottom toward the card slot 14 to form a limiting portion 2211 that can elastically cooperate with the card slot 14, and the card foot 222 is provided at the lower end of the limiting portion 2211. This structure is conducive to improving the elasticity of the lower part of the buckle 22, thereby further improving the convenience of disassembly and assembly, and preventing the buckle from being damaged due to extrusion.

[0037] The buckle structures of this embodiment are in two groups and are arranged at intervals in the circumferential direction of the filter plate 2.

[0038] In this embodiment, a water pump is provided in the water return area 11, and the filter plate 2 includes a main body 201 and an auxiliary part 202 for installing a water outlet pipe of the water pump. The main body 201 is detachably restrained at the bottom of the box body 1 by a snap-fit ​​structure, and the auxiliary part 202 is detachably connected to the main body 201 and locked at the bottom of the box body 1. The area of ​​the auxiliary part 202 is very small, and it is only used to position the water outlet pipe of the water pump, and will not block the maintenance of the water pump in the up and down directions. The auxiliary part 202 is locked to the bottom of the box body 1 by screws, which can improve the positioning stability of the water outlet pipe, and the main body 201 and the auxiliary part 202 are detachably connected so as not to affect the disassembly and assembly of the main body 201.

[0039] The main part 201 is provided with a convex card 23 on the side wall corresponding to the auxiliary part 202, and correspondingly, the side wall of the auxiliary part 202 is provided with a bayonet 24 extending from bottom to top and for the convex card 23 to be clamped therein. This structure facilitates the upper and lower limit of the main part 201 and the auxiliary part 202 to prevent the main part 201 from tilting up, and when disassembling the main part 201, the other edge of the main part 201 can be opened to cancel the limit of the convex card 23 and the bayonet 24, which is convenient for operation.

[0040] The edge where the auxiliary part 202 is connected to the main part 201 is provided with a slag guide groove 25 hidden at the bottom of the main part 201. The slag guide groove 25 is U-shaped and partially partitioned in the horizontal direction to form a guide port 251. This structure can guide away the residue at the gap between the main part 201 and the auxiliary part 202 in time to avoid the accumulation of residue and the breeding of bacteria.

[0041] The upper surface of the filter plate 2 of this embodiment is provided with legs 26 for lifting the filter plate 2, and there are two legs 26 arranged at intervals. This structure facilitates lifting the filter plate 2 when disassembling it, and is convenient for operation.

[0042] The edge of the filter plate 2 of this embodiment is supported on a support 12 outside the return water area 11, and the lower surface of the filter plate 2 is detachably connected to the inner side of the support 12 and the inner wall of the return water area 11 under the support 12 near the edge through a snap structure. The supporting force on the edge of the filter plate 2 and the snap force on the lower surface of the filter plate 2 are balanced with each other, thereby achieving stable installation of the filter plate 2. The filter plate 2 is limited to the bottom of the box body 1 only by the snap structure, which is convenient for disassembly and assembly, and brings convenience to the maintenance of functional parts in the return water area 11.

[0043] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
