Description

TECHNICAL FIELD

[0001] The present application relates to a household appliance. BACKGROUND

[0002] For household appliances with functional inner cavities, such as dishwashers, steam ovens, ovens, etc., due to functional requirements, a door body capable of opening or covering the opening of the cabinet is usually provided at the opening of the cabinet.

[0003] As disclosed in the Chinese patent application for invention with patent number CN201811595226.5 (publication number CN109620090A), the opening and closing door structure of the dishwasher comprises a sink with an opening, and a door assembly for opening and closing the opening.

[0004] For such a top opening and closing door type household appliance, the gap between the bottom of the door body and the top of the sink is very small whether the door body is in an open or closed state. Over time, dust and dirt will accumulate in this small space, making it difficult to clean. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a household appliance that facilitates cleaning the gap between the door body and the sink.

[0006] The technical solution adopted by the present application to solve the above technical problem is: a household appliance, comprising

[0007] a sink with an open top forming an opening;

[0008] a door body rotatably arranged at the opening of the sink, the door body being capable of opening or closing the opening of the sink;

[0009] characterized in that it further comprises

[0010] a fixed plate fixedly arranged at the top of the sink and located at the rear of the sink, the fixed plate being provided with a sliding groove, the sliding groove comprising a vertical segment and an arc segment arranged in sequence from top to bottom and connected, the vertical segment extending vertically, and the arc segment being an arc structure extending forward from top to bottom and arching upward;

[0011] a mounting shaft arranged at the rear of the door body, the mounting shaft being inserted into the sliding groove and capable of sliding along the sliding groove.

[0012] The door body can be manually moved along the vertical segment, but it is laborious, so the household appliance further comprises a driving assembly connected with the door body, and the mounting shaft can be moved upward along the vertical segment under the action of the driving assembly in the state that the mounting shaft is located at the lower end of the vertical segment. The door body is driven by the driving assembly to move upward along the vertical segment, without manually lifting the door body upward, which is more labor-saving. When the door body does not need to be too high, the driving assembly is not in operation, and the door body automatically slides downward along the vertical segment under the action of gravity.

[0013] The driving assembly can have various structural forms, such as a motor, but the motor structure is complex and high in cost, so the driving assembly comprises a first magnetic member arranged on the groove body and a second magnetic member arranged on the door body, and the first magnetic member can be opposite to the second magnetic member and magnetically repel each other in the state that the mounting shaft is located at the lower end of the vertical segment. The driving assembly has a simple structure, and the door body is moved upward along the vertical segment by the repulsion force between the first magnetic member and the second magnetic member.

[0014] The mounting shaft can be placed at the connection between the vertical segment and the arc segment, and if there is no dirt between the door body and the groove body, the door body does not need to be lifted and the mounting shaft is positioned at the lower end of the vertical segment.

[0015] In order to make the driving assembly not work when the door body does not need to be lifted, the groove body is provided with a mounting member and a driving member connected with the driving assembly, the first magnetic member is arranged on the mounting member, and the mounting member can be moved to a first position and a second position relative to the groove body under the action of the driving member. In the state that the mounting member is located at the lower end of the vertical segment and the mounting member is in the first position, the first magnetic member is opposite to the second magnetic member and magnetically repels each other. In the state that the mounting member is located at the lower end of the vertical segment and the mounting member is in the second position, the first magnetic member and the second magnetic member are disengaged. When the gap between the door body and the groove body needs to be cleaned, the mounting member is in the first position, and under the repulsion between the first magnetic member and the second magnetic member, the mounting shaft moves upward along the vertical segment, the door body moves upward synchronously, and the gap between the door body and the groove body is increased, which is convenient for cleaning. When the gap between the door body and the groove body does not need to be cleaned, the mounting member is in the second position, and the first magnetic member and the second magnetic member will not generate repulsion force, the mounting shaft is located at the lower end of the vertical segment, and the door body is in a lower position.

[0016] The mounting member can be installed on the groove body in a translational manner, but it needs to reserve a moving space for the mounting member on the groove body, which occupies a large space, so the mounting member is rotatably installed on the groove body around an axis extending in the left-right direction. In this way, the groove body only needs to have a space for accommodating the mounting member, and the space can be used for rotating the mounting member, which is compact in structure.

[0017] Preferably, the two mounting members are arranged left and right, and the first magnetic member and the second magnetic member are each provided with two corresponding mounting members, and the driving member is drivingly connected to the two mounting members. In this way, the door body is uniformly stressed and moves smoothly.

[0018] In order to facilitate the magnetic cooperation of the first magnetic member and the second magnetic member, the bottom of the front wall surface of the door body is provided with a groove, the groove is provided with a mounting block, the second magnetic member is arranged on the mounting block, and the door body is further provided with a torsional spring acting on the mounting block. The mounting block is kept moving out of the groove and above the mounting member under the action of the torsional spring, facilitating the cooperation of the first magnetic member and the second magnetic member. In the closed state of the door body, the mounting block is located in the groove and does not affect the closing of the door body.

[0019] In order to prevent hard interference between the rear part of the door body and the groove body during the opening of the door body, damage to the components, the door body is provided with a roller that can rotate around an axis extending in the left and right directions. In the state that the mounting shaft slides in the arc-shaped section, the roller is pressed against the top wall of the groove body and rotates. The arrangement of the roller reduces the friction between the rear part of the door body and the groove body, and also makes the opening of the door body more smooth and easy.

[0020] In order to facilitate the opening of the door body, the door body or the groove body is provided with a supporting block. In the closed state of the door body, the supporting block is supported between the door body and the groove body. In this way, there is a gap between the door body and the groove body in the closed state of the door body, facilitating the user to stretch his hand into the gap to open the door body.

[0021] Preferably, the two mounting members are arranged left and right, and the first magnetic member and the second magnetic member are each provided with two corresponding mounting members, and the driving member is drivingly connected to the two mounting members. In this way, the door body is uniformly stressed and moves smoothly.

[0022] The household appliance can be a sterilization cabinet, a steamer, etc. The household appliance is a cleaning machine capable of cleaning tableware and / or fruits and vegetables.

[0023] Compared with the prior art, the advantages of the present application are as follows: the present application provides a fixed plate on the groove body, a sliding groove on the fixed plate, and the sliding groove includes a vertical section and an arc-shaped section. In normal use, the door body is opened to the upper end of the arc-shaped section of the mounting shaft. After the door body of the present application is opened to the upper end of the arc-shaped section of the mounting shaft, the mounting shaft moves upward along the vertical section, the door body is lifted, the gap between the door body and the groove body is increased, and cleaning is facilitated.
