Description

Technical Field

[0001] The invention relates to a household appliance. Background Art

[0002] For household appliances with functional inner cavities, such as dishwashers, steamers, ovens, etc., due to functional requirements, a door body that can open or cover the opening is usually provided at the opening of the box body.

[0003] As disclosed in the Chinese invention patent application with patent number CN201811595226.5 (publication number CN109620090A), "An opening and closing door structure of a dishwasher, a dishwasher having the same, and an opening and closing door method of a dishwasher", the opening and closing door structure of the dishwasher includes: a sink having an opening; and a door assembly, which is used to open and close the opening.

[0004] For this type of household appliance with a top-opening door, whether the door is open or closed, the gap between the bottom of the door and the top of the groove is very small. Over time, dust or dirt will accumulate here, and the space here is small, and it is difficult for cleaning tools to reach into it, making cleaning difficult. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a household appliance which is convenient for cleaning the gap between a door body and a slot body in view of the current status of the prior art.

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

[0007] A trough body, with a top open to form an opening;

[0008] A door body is rotatably disposed at the opening of the slot body, and the door body can open or close the opening of the slot body;

[0009] It is characterized by that it also includes

[0010] A fixed plate, fixedly arranged on the top of the trough body and located at the rear of the trough body, the fixed plate is provided with a slide groove, the slide groove comprises a vertical section and an arc section which are sequentially arranged and connected from top to bottom, the vertical section extends vertically, and the arc section is an arc structure extending forward from top to bottom and arching upward;

[0011] The installation shaft is arranged at the rear part of the door body, and the installation shaft is inserted in the slide groove and can slide along the slide groove.

[0012] The door body can be moved manually along the vertical section, but this is laborious, so the household appliance further includes a driving assembly connected to the door body, and when the mounting shaft is located at the lower end of the vertical section, the mounting shaft can move upward along the vertical section under the action of the driving assembly. The door body is driven to move upward along the vertical section by the driving assembly, and there is no need to manually lift the door body upward, which is labor-saving; when the door body does not need to be too high, the driving assembly does not work, and the door body will automatically slide downward along the vertical section under gravity.

[0013] The driving assembly can have a variety of structural forms, such as a motor, but the motor structure is complex and costly, so the driving assembly includes a first magnetic member arranged on the slot body and a second magnetic member arranged on the door body, and when the mounting shaft is located at the lower end of the vertical section, the first magnetic member can be opposite to the second magnetic member and magnetically repel each other. The driving assembly has a simple structure, and the door body slides upward along the vertical section through the repulsive force between the first magnetic member and the second magnetic member.

[0014] The installation shaft can be placed at the connection between the vertical section and the arc section. If there is no dirt between the door body and the trough body, there is no need to clean it or lift the door body. The installation shaft can be positioned at the connection between the vertical section and the arc section, that is, the lower end of the vertical section.

[0015] In order to prevent the driving assembly from working when the door body does not need to be lifted, a mounting member and a driving member connected to the mounting member are provided on the slot body. The first magnetic member is provided on the mounting member. The mounting member can move to the first position and the second position relative to the slot body under the action of the driving member. When the mounting member is in the first position and the mounting member is located at the lower end of the vertical section, the first magnetic member and the second magnetic member are opposite and magnetically repelled. When the mounting member is in the second position and the mounting member is located at the lower end of the vertical section, the first magnetic member and the second magnetic member release the magnetic cooperation. When it is necessary to clean the gap between the door body and the slot body, the mounting member is in the first position. When the mounting shaft is located at the lower end of the vertical section, under the repulsive action between the first magnetic member and the second magnetic member, the mounting circumference moves up along the vertical section, the door body moves up synchronously, and the gap between the door body and the slot body is increased, which is convenient for cleaning. When it is not necessary to clean the gap between the door body and the slot body, the mounting member is in the second position. At this time, no repulsive force is generated between the first magnetic member and the second magnetic member. The mounting shaft is located at the lower end of the vertical section, and the door body is in a lower position.

[0016] The mounting piece can be installed on the trough body in a translational manner, but this requires reserving space for the mounting piece to move on the trough body, which takes up a large space. Therefore, the mounting piece is rotatably installed on the trough body around an axis extending in the left and right directions. In this way, as long as there is space on the trough body for accommodating the mounting piece and the space can allow the mounting piece to rotate, the structure is compact.

[0017] Preferably, there are two mounting members spaced apart on the left and right sides, and correspondingly, there are two first magnetic members and two second magnetic members, and the driving member is drivingly connected to both mounting members. In this way, the door body is evenly stressed and moves smoothly.

[0018] In order to facilitate the magnetic cooperation between the first magnetic part and the second magnetic part, a groove is provided at the bottom of the front wall of the door body, a mounting block is provided in the groove, the second magnetic part is arranged on the mounting block, and the door body is also provided with a torsion spring acting on the mounting block. Under the action of the torsion spring, the mounting block maintains a tendency to move out of the groove and directly above the mounting part, so as to facilitate the cooperation between the first magnetic part and the second magnetic part. When the door body is closed, the mounting block is located in the groove and will not affect the closing of the door body.

[0019] In order to prevent hard interference between the rear of the door body and the slot body and damage to components during the door opening process, the door body is provided with a roller that can rotate around an axis extending in the left and right directions. When the mounting shaft slides in the arc segment, the roller is pressed against the top wall of the slot body and rotates. The setting of the roller reduces the friction between the rear of the door body and the slot body, and also makes the opening of the door body smoother and easier.

[0020] In order to facilitate opening the door body, a support block is provided on the door body or the slot body. When the door body is closed, the support block is supported between the door body and the slot body. In this way, when the door body is closed, there is a gap between the door body and the slot body, which is convenient for the user to reach into the gap to open the door body.

[0021] Preferably, there are two fixing plates spaced apart on the left and right sides, and correspondingly, there are two mounting shafts, so that the force is evenly applied to the door body during opening and closing, making the door opening and closing smooth.

[0022] The household appliance may be a disinfection cabinet, a steamer, etc., and the household appliance is a washing machine capable of washing tableware and / or fruits and vegetables.

[0023] Compared with the prior art, the advantages of the present invention are as follows: the present invention arranges a fixed plate on the trough body, and a slide groove is arranged on the fixed plate, and the slide groove includes a vertical section and an arc section. During normal use, the door body is opened until the installation shaft moves to the upper end of the arc section. After the door body of the present invention is opened until the installation shaft moves to the upper end of the arc section, the installation shaft moves upward along the vertical section, lifting the door body and increasing the gap between the door body and the trough body for easy cleaning.

[0036] The present invention is further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 12 As shown, the household appliance of this preferred embodiment includes a tank body 1, a door body 2, a fixing plate 3, a mounting shaft 21 and a driving assembly.

[0038] The top of the tank body 1 is open to form an opening 11, and the door body 2 is rotatably arranged at the opening 11 of the tank body 1, and the door body 2 can open or close the opening 11 of the tank body 1. When the door body 2 opens the tank body 1, the door body 2 is in a vertically extended state, and when the door body 2 closes the tank body 1, the door body 2 is in a horizontally extended state.

[0039] A support block 12 is provided on the door body 2 or the slot body 1. When the door body 2 is closed, the support block 12 is supported between the door body 2 and the slot body 1. In this way, when the door body 2 is closed, there is a gap between the door body 2 and the slot body 1, which is convenient for the user to reach into the gap to open the door body 2.

[0040] The fixed plate 3 is fixedly arranged on the top of the trough body 1 and is located at the rear of the trough body 1. A slide groove 31 is provided on the fixed plate 3. The slide groove 31 includes a vertical section 311 and an arc section 312 which are arranged and connected in sequence from top to bottom. The vertical section 311 extends vertically, and the arc section 312 is an arc structure extending forward from top to bottom and arching upward. The installation shaft 21 is arranged at the rear of the door body 2. The installation shaft 21 is inserted into the slide groove 31 and can slide along the slide groove 31.

[0041] In normal use, the door body 2 is opened until the mounting shaft 21 moves to the upper end of the arc segment 312 (such as Fig.11 , 12 If the gap between the door body 2 and the tank body 1 needs to be cleaned, the door body 2 is opened until the mounting shaft 21 moves to the upper end of the arc segment 312, so that the mounting shaft 21 moves upward along the vertical segment 311, the door body 2 is lifted, and the gap between the door body 2 and the tank body 1 is increased (such as Figure 2 , 3 The state shown in the figure) is used to facilitate cleaning the gap between the door body 2 and the tank body 1. When the door body 2 is closed, the mounting shaft 21 is located at the lower end of the arc segment 312.

[0042] The driving assembly is connected to the door body 2. When the installation shaft 21 is located at the lower end of the vertical section 311, the installation shaft 21 can move upward along the vertical section 311 under the action of the driving assembly. The door body 2 is driven to move upward along the vertical section 311 by the driving assembly. There is no need to lift the door body 2 upward manually, which is more labor-saving. When there is no need to lift the door body 2, the driving assembly does not work, and the door body 2 will move to the lower end of the vertical section 311 where the installation shaft 21 is located under gravity.

[0043] In this embodiment, the driving assembly includes a first magnetic component 41 arranged on the slot body 1 and a second magnetic component 42 arranged on the door body 2. When the mounting shaft 21 is located at the lower end of the vertical section 311 (i.e., the upper end of the arc section 312), the first magnetic component 41 can be relative to and magnetically repel the second magnetic component 42. Through the repulsive force between the first magnetic component 41 and the second magnetic component 42, the door body 2 automatically slides upward along the vertical section 311.

[0044] In this embodiment, the installation shaft 21 can be placed at the connection between the vertical section 311 and the arc section 312. If there is no dirt between the door body 2 and the trough body 1, there is no need to clean it or lift the door body 2. The installation shaft 21 can be positioned at the connection between the vertical section 311 and the arc section 312, that is, the lower end of the vertical section 311 and the upper end of the arc section 312.

[0045] The tank body 1 is provided with a mounting member 5 and a driving member 6 connected to the mounting member 5. The first magnetic member 41 is provided on the mounting member 5. The mounting member 5 can move to a first position and a second position relative to the tank body 1 under the action of the driving member 6. When the mounting member 5 is in the first position and the mounting member 21 is located at the lower end of the vertical section 311, as shown in FIG. Figure 5 As shown, the first magnetic member 41 and the second magnetic member 42 are opposite to each other and magnetically repel each other; when the mounting member 5 is in the second position and the mounting shaft 21 is located at the lower end of the vertical section 311, as shown Fig.12 As shown, the first magnetic member 41 and the second magnetic member 42 are released from magnetic cooperation.

[0046] When it is necessary to clean the gap between the door body 2 and the slot body 1, the mounting member 5 is in the first position, and when the mounting shaft 21 is located at the lower end of the vertical section 311, under the repulsive action between the first magnetic member 41 and the second magnetic member 42, the mounting shaft 21 moves up along the vertical section 311, and the door body 2 moves up synchronously, and the gap between the door body 2 and the slot body 1 is increased to facilitate cleaning; when it is not necessary to clean the gap between the door body 2 and the slot body 1, the mounting member 5 is in the second position, at this time, no repulsive force is generated between the first magnetic member 41 and the second magnetic member 42, the mounting shaft 21 is located at the lower end of the vertical section 311, and the door body 2 is in a lower position.

[0047] like Fig.10 , 12 As shown, the mounting member 5 is rotatably mounted on the trough body 1 around an axis extending in the left-right direction, and there are two mounting members 5 spaced apart from each other. Correspondingly, there are two first magnetic members 41 and two second magnetic members 42, and the driving member 6 is connected to the two mounting members 5 by a driving rod 61. In this way, the door body 2 is evenly stressed and moves smoothly. The driving member 6 can be a motor.

[0048] like Figure 5 As shown, a groove 22 is provided at the bottom of the front wall of the door body 2, a mounting block 7 is provided in the groove 22, a second magnetic member 42 is provided on the mounting block 7, and a torsion spring 71 acting on the mounting block 7 is also provided on the door body 2. Under the action of the torsion spring 71, the mounting block 7 maintains a tendency to move outside the groove 22 and directly above the mounting member 5.

[0049] In this embodiment, the elastic member is a torsion spring 71, one end of which is connected to the wall surface of the groove 22, and the other end is connected to the mounting block 7. When the mounting block 7 is moved to the outside of the groove 22, the mounting block 7 partially abuts against the top wall surface of the groove 22 to limit the mounting block 7. When the door body 2 is opened, the mounting block 7 moves to the outside of the door body 2 under the action of the torsion spring 71, so that the first magnetic member 41 and the second magnetic member 42 cooperate. When the door body 2 is closed, the mounting block 7 is located in the groove 22.

[0050] like Fig. 9 As shown, the door body 2 is provided with a roller 8 which can rotate around an axis extending in the left and right directions. When the mounting shaft 21 slides in the arc segment 312, the roller 8 presses against the top wall of the slot body 1 and rotates. The setting of the roller 8 reduces the friction between the rear of the door body 2 and the slot body 1, and also makes the opening of the door body 2 smoother and easier.

[0051] In this embodiment, there are two fixing plates 3 spaced apart on the left and right sides, and correspondingly, there are two mounting shafts 21, which are respectively arranged on the left and right side walls of the door body. In this way, the door body 2 is subjected to uniform force during opening and closing, so that the door can be opened and closed smoothly.

[0052] The household appliance may be a disinfection cabinet, a steamer, etc. The household appliance in this embodiment is a washing machine capable of washing tableware and / or fruits and vegetables.
