Description

Technical Field

[0001] The invention relates to the technical field of kitchen cleaning machines, in particular to a cleaning machine with a door that can automatically open and close. 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] Due to the limitation of the cabinet, the door structure of the sink-type cleaning machine is generally a flap-type structure, such as the structure disclosed in the Chinese patent application "Sink-type Cleaning Machine" (application number: CN201710939807.5) with application publication number CN108056732A, in which the cleaning machine has a sink body with a washing space and an open top, and a cover plate that can be opened or closed relative to the top opening of the sink body and is movably arranged on the top of the sink body. The edge of the cover plate is connected to the top open edge of the sink body through a damping shaft. When opening, the cover plate needs to be manually flipped back, and when closing, the user needs to press the door body by hand, which is inconvenient to use; and there may be a large amount of high-temperature steam in the sink that has just been cleaned. When the door body is opened, the hot air hits the face, which seriously affects the user's experience. In addition, the door body that is naturally pressed down by gravity has poor sealing with the top open edge of the sink body. When the water temperature in the sink is high, there is a problem of overflow, which affects the use.

[0004] Therefore, for current water tank type cleaning machine, further improvement needs to be made. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning machine which adopts a double-opening door to avoid hot air blowing on the face and is easy to operate in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, including a sink body and a door body, the sink body is hollow inside to form a washing space, the washing space has a top opening, and the door body can be opened and closed on the sink body relative to the top opening, characterized in that: the door body includes a front door panel and a rear door panel that are matched to each other, the front edge of the front door panel can be rotatably connected to the front edge of the top opening of the sink body, and the rear edge of the rear door panel can be rotatably connected to the rear edge of the top opening of the sink body, and the sink body is provided with a rotating mechanism that can make the front door panel and the rear door panel rotate relative to the top opening edge of the sink body.

[0007] In the above scheme, the rotating mechanism has a support rod capable of lifting or pulling down the front door panel and the rear door panel, and the support rod is connected to a driving mechanism capable of moving the support rod so as to lift or pull down the front door panel / rear door panel. When the support rod lifts up the front door panel / rear door panel, the door body can be opened, and when the support rod pulls down the front door panel / rear door panel, the door body can be relatively closed, providing conditions for opening or closing the door body.

[0008] Preferably, the support rod comprises a first support rod and a second support rod, the upper end of the first support rod is connected to the lower surface of the front door panel, the upper end of the second support rod is connected to the lower surface of the rear door panel, and the lower ends of the first support rod and the second support rod extend downward and are connected to the driving mechanism. With the above structure, the first support rod and the second support rod are synchronously driven by the same driving mechanism, so that the lifting or pulling down process of the front door panel and the rear door panel is carried out synchronously, which not only simplifies the overall structure, but also helps to improve the user experience.

The support rod is formed into an arc structure arched toward the middle part of the water tank body. With such a structure, the matching resistance at the connection between the support rod and the corresponding connecting rod can be reduced, the smoothness and stability of the door closing process can be improved, and the motor load can be reduced.

[0018] To facilitate assembly, the upper end of the pull rod is provided with a U-shaped groove extending from top to bottom, and the openings on both sides of the U-shaped groove are arranged corresponding to the second end of the first connecting rod and the second end of the second connecting rod respectively. The second end of the first connecting rod and the second end of the second connecting rod overlap front and back and extend into the U-shaped groove and are provided with a second assembly hole extending along the length direction of the corresponding first connecting rod / second connecting rod. The second pin shaft passes through the second assembly holes on the first connecting rod and the second connecting rod to limit the two to rotate in the U-shaped groove and allow lateral displacement.

[0019] Preferably, the width of the front door plate in the front-to-back direction is smaller than the width of the rear door plate in the front-to-back direction. This structure can use the front door plate to block hot air while facilitating users to take and put items in the water tank body.

[0020] Preferably, the front edge of the rear door panel is provided with a sealing strip arranged along the length direction, and a sealing groove is provided in the middle of the sealing strip, in which the rear edge of the front door panel can be clamped when the front door panel and the rear door panel are relatively closed.
