Description

Technical Field

[0001] The invention belongs to the field of dishwashers, and in particular relates to a dishwasher with an electromagnetic suction type upper cover and a method for controlling the opening and closing of the upper cover. Background Art

[0002] At present, most of the doors of undercounter dishwashers on the market generally use buckles as locking mechanisms. When closing the door, the side door is closed by the buckle, but the buckle mechanism has a complex structure and a high failure rate, and is not easy to use frequently.

[0003] The Chinese patent application number CN201120484676.4 discloses a side door suction device for a dishwasher, comprising a side door body and a side plate connected to the outer peripheral surface of the side door body, the side plates on the left and right sides of the side door body are connected to the water retaining plate through the door lining, the bottom of the water retaining plate on both sides is provided with a door shaft for connecting with the dishwasher body, and the surface of the side plate at the upper end of the side door body is provided with a magnet for sucking the side door body and the dishwasher body. However, due to the fixed position of the magnet, the structure makes the fitting attraction between the side door body and the dishwasher body constant. If the position is close, the magnetic force is large, which affects the opening of the side door body and requires a large force to open it. If the position is far away, the magnetic force is small, which affects the closing of the side door body, which is inconvenient for users to use.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dishwasher with an electromagnetic suction type upper cover and an upper cover opening and closing control method, which adopts an electromagnet as a locking mechanism, has a simple structure, is easy to operate and has a low failure rate.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dishwasher with an electromagnetic suction type upper cover, including a dishwasher body, an upper cover fixed on the dishwasher body at one side and rotatable to open and close the dishwasher, a permanent magnet is provided on the upper cover, an electromagnet is provided at a position corresponding to the permanent magnet on the dishwasher body, and an elastic structure that can pop open the upper cover is also provided on the dishwasher body or the upper cover.

[0007] The elastic structure is located on the lower surface of the upper cover in contact with the dishwasher body, and a sink groove is provided on the dishwasher body at a position corresponding to the elastic structure. When the electromagnet is energized, the upper cover and the dishwasher body are closed, and the elastic structure on the upper cover is squeezed and compressed into the sink groove on the dishwasher body, so that there is no gap between the upper cover and the dishwasher body; when the electromagnet is not energized, the compression force on the elastic structure disappears, the elastic structure instantly pops open, and returns to a naturally stretched state, and the upper cover is popped open.

[0008] The elastic structure is located on the upper surface where the dishwasher body contacts the upper cover, and a sink groove is provided at the corresponding position of the upper cover and the elastic structure. When the electromagnet is energized, the upper cover and the dishwasher body are closed, and the elastic structure on the dishwasher body is squeezed and compressed into the sink groove of the upper cover, so that there is no gap between the upper cover and the dishwasher body; when the electromagnet is not energized, the compression force on the elastic structure disappears, the elastic structure instantly pops open, and returns to a naturally stretched state, and the upper cover is popped open.

[0009] The inner cavity of the sink is larger than the outer shape of the elastic structure, and the depth of the sink is larger than the length of the elastic structure when it is fully compressed and smaller than the length of the elastic structure in a naturally stretched state. The inner cavity of the sink is larger than the outer shape of the elastic structure, so that the elastic structure does not interfere with the inner cavity of the sink when it enters the sink under compression; the depth of the sink is larger than the length of the elastic structure when it is fully compressed, so that the elastic structure can be completely immersed in the sink when it is compressed, and will not interfere with the upper cover or the main body of the dishwashing body; the depth of the sink is smaller than the length of the elastic structure in a naturally stretched state, so that the elastic structure is in a compressed state when immersed in the sink, and when the electromagnet is not energized, the compression force on the elastic structure disappears, and it recovers from the compressed state to the naturally stretched state, and the upper cover is popped open.

[0010] The elastic structure is a spring. Springs are commonly used in life and are widely used. The elastic structure can achieve the desired purpose and reduce costs by using the spring.

[0011] The connection between the dishwasher body and the upper cover is provided with a damping device for controlling the static angle of the upper cover. By adjusting the damper, the tension of the damper and the gravity of the upper cover will be balanced at a position between α∝0°, and the upper cover will be static at a position with an angle α to the horizontal direction.

[0012] The elastic structure is fixed on the dishwasher body or the upper cover by bonding or mechanical fixing.

[0013] The permanent magnet is located between the upper and lower interlayers of the upper cover and is fixed by bonding or mechanical fixing, which prevents the permanent magnet from moving and colliding with the upper cover when the upper cover is opened or closed, thereby extending the service life of the permanent magnet.

[0014] The electromagnet is located in a groove at a position corresponding to the permanent magnet on the dishwasher body and is fixed by bonding or mechanical fixing. The electromagnet is located in the groove and does not protrude from the dishwasher body, ensuring that the upper cover and the dishwasher body can be completely closed. The electromagnet is fixed by bonding or mechanical fixing, which prevents the electromagnet from moving and colliding with the dishwasher body, thereby extending the service life of the electromagnet.

[0015] A method for controlling the opening and closing of the upper cover of a dishwasher with an electromagnetic suction type upper cover is provided. When the electromagnet is powered on, the permanent magnet and the electromagnet are attracted together, and the upper cover is closed; when the electromagnet is powered off, the magnetic attraction between the permanent magnet and the electromagnet disappears, and the elastic force of the elastic mechanism causes the upper cover to open.

[0016] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0017] 1. An elastic mechanism is provided on the dishwasher body or upper cover. When the electromagnet is not energized, the compression force on the elastic structure disappears, the elastic structure instantly pops open, and returns to its natural elongated state, and the upper cover pops open;

[0018] 2. A sink groove is provided at the corresponding position of the elastic structure. When the electromagnet is energized, the upper cover and the dishwasher body are closed, and the elastic structure is squeezed and compressed into the sink groove, so that there is no gap between the upper cover and the dishwasher body;

[0019] 3. The inner cavity of the sink is larger than the outer shape of the elastic structure, so that the elastic structure does not interfere with the inner cavity of the sink when it is compressed into the sink;

[0020] 4. The depth of the sink is greater than the length of the elastic structure when it is fully compressed, so that the elastic structure can be completely immersed in the sink when compressed without interfering with the upper cover or the main body of the dishwashing body;

[0021] 5. The depth of the sink is smaller than the length of the elastic structure in the natural extension state, so that the elastic structure is in a compressed state when immersed in the sink. When the electromagnet is not energized, the compression force on the elastic structure disappears, and the elastic structure recovers from the compressed state to the natural extension state, and the upper cover is popped open;

[0022] 6. The elastic structure is a spring. Springs are commonly used in life and are widely used. The elastic structure can achieve the desired purpose and reduce costs by using springs;

[0023] 7. A damping device for controlling the static angle of the upper cover is provided at the connection between the dishwasher body and the upper cover. By adjusting the damper, the tension of the damper and the gravity of the upper cover will be balanced at a position between α∝0°, and the upper cover will be static at a position with an angle of α to the horizontal direction;

[0024] 8. The permanent magnet is located between the upper and lower layers of the upper cover and is fixed by bonding or mechanical fixing, which prevents the permanent magnet from moving and colliding with the upper cover when the upper cover is opened or closed, thereby extending the service life of the permanent magnet;

[0025] 9. The electromagnet is located in a groove on the dishwasher body at a position corresponding to the permanent magnet, and is fixed by bonding or mechanically. The electromagnet is located in the groove and does not protrude from the dishwasher body, ensuring that the upper cover and the dishwasher body can be completely closed. The electromagnet is fixed by bonding or mechanically, which avoids the movement of the electromagnet and the collision with the dishwasher body, thereby extending the service life of the electromagnet.
