[0002] The sink-type dishwasher adopts an upward-turning door body, and the switch assembly of the dishwasher is usually installed on the door body to facilitate user operation. For example, Chinese utility model patent ZL 202022830835.3 "A door body installation structure of a sink-type dishwasher" discloses a sink-type dishwasher including a door body structure.

[0003] In the above-mentioned existing dishwashers, the adhesive bracket of the switch assembly is usually fastened to the door frame by screws, the door glass is bonded to the adhesive bracket and the door frame, and the switch assembly is located in the interlayer between the door frame and the door glass. The damping shaft of the door body is installed at the rear end of the door body frame, and the door body rotates around the center of the shaft in the sink of the trough panel to open and close.

[0004] For sink dishwashers that use a sunken door, it is inevitable that there will be a gap between the rear edge of the door and the sunken groove when the door is closed. The existence of this gap is not only unsightly, but also difficult to clean if small objects get into the gap. Since there is often water accumulation in the sunken groove, mold and bacteria will grow over time. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine capable of covering the gaps in a closed state to prevent debris from entering and bacteria from growing, in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A cleaning machine comprises a water tank and a door body, wherein the rear edge of the door body is rotatably connected to the rear edge of the top opening of the water tank, and a sinking groove is arranged at the periphery of the top opening of the water tank. In a closed state, the door body is located in the sinking groove, and a gap is formed between the rear edge of the door body and the rear side wall of the sinking groove. A flap that can be flipped up and down relative to the door body is arranged at the rear edge of the door body. In a closed state, the flap is flipped to be flush with the upper surface of the door body and covers the gap. In the process of opening the door, the flap is folded and flipped relative to the upper surface of the door body to form an anti-interference structure for opening the door.

[0008] Preferably, the front edge of the flap is provided with a rotating shaft, and correspondingly, the rear edge of the door body is provided with a clamping groove, in which the rotating shaft can be rotatably clamped. With such a structure, a compact rotating connection between the flap and the rear edge of the door body can be achieved in a very small space.

[0009] Preferably, the clamping groove is formed into a bowl-shaped structure with an opening facing inward, and the rear part of the clamping arm forming the clamping groove is located outside the rear edge of the door body, and the flap is provided with a notch for the rear part of the clamping arm to pass through. With the above structure, the flap and the rear edge of the door body are assembled compactly, and the flip angle of the flap can be easily controlled.

[0010] Preferably, the outer peripheral surface of the rear part of the clamp arm is an arc structure, and accordingly, the notch forms an arc surface corresponding to the side wall of the arc structure to rotate with it. This structure is not only convenient for making the notch gap as small as possible, but also convenient for controlling the flip angle of the flap.

[0011] Preferably, the clamping groove and the rotating shaft matching structure are two groups and are arranged at intervals on the rear edge of the door body. An elastic member is arranged between the two groups of the clamping groove and the rotating shaft matching structure to enable the flap to always keep the tendency to flip to be flush with the upper surface of the door body. The above structure is provided to improve the flipping stability of the flap.

[0012] In the utility model, an elastic member is arranged between the flap and the rear edge of the door body, which can keep the flap always turning over to be flush with the upper surface of the door body. With such a structure, the flap can automatically turn over to cover the gap when the door is closed.

[0013] Preferably, the elastic member is a torsion spring, the middle part of which is a torsion spring sleeve sleeved outside the rotating shaft, the torsion spring sleeve is provided with a first torsion arm extending backward and constrained on the lower surface of the flap, and the torsion spring is provided with a second torsion arm extending forward and constrained on the lower surface of the door body. The above structure is adopted to provide a torsion force for the flap to flip, and during the opening process, when the flap interferes with the rear side wall of the sink groove, the flap overcomes the torsion force of the torsion spring and automatically folds.

[0014] In order to facilitate the installation of the torsion spring, a first slot for inserting the first torsion arm is provided on the lower surface of the flap, and the opening of the first slot is arranged forward; a second slot for inserting the second torsion arm is provided on the rear edge of the door body.

[0015] Compared with the prior art, the advantages of the present invention are: a flip-up flap is provided at the rear edge of the door body. When the door is closed, the flap flips to be flush with the upper surface of the door body and covers the gap to prevent debris from entering and bacteria from breeding; during the door opening process, the flap folds and flips relative to the upper surface of the door body to form an anti-interference structure for door opening, which greatly improves the user experience.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown in Figure 4, the cleaning machine of this embodiment includes a water tank 1 and a door body 2. The rear edge of the door body 2 is rotatably connected to the rear edge of the top opening 11 of the water tank 1. A sink groove 12 is arranged on the periphery of the top opening 11 of the water tank 1. In the closed state, the door body 2 is located in the sink groove 12, and a gap 10 is formed between the rear edge of the door body 2 and the rear side wall of the sink groove 12. A flap 3 that can be flipped up and down relative to the door body 2 is arranged at the rear edge of the door body 2. In the closed state, the flap 3 flips to be flush with the upper surface of the door body 2 and covers the gap 10. In the process of opening the door, the flap 3 is folded and flipped relative to the upper surface of the door body 2 to form an anti-interference structure for opening the door.

[0022] The front edge of the flap 3 is provided with a rotating shaft 31, and correspondingly, the rear edge of the door body 2 is provided with a clamping groove 21, and the rotating shaft 31 can be rotatably clamped in the clamping groove 21. With such a structure, a compact rotating connection between the flap and the rear edge of the door body can be realized in a very small space.

[0023] The clamping groove 21 is formed into a bowl-shaped structure with an opening facing in the direction, and the rear part of the clamping arm 211 forming the clamping groove 21 is located outside the rear edge of the door body 2, and the flap 3 is provided with a notch 32 for the rear part of the clamping arm 211 to pass through.
