Description

[0002] With the increasing degree of intelligence of kitchen appliances, intelligent door opening has become a trend in user interaction experience, such as the pressing automatic door opening method. When the door body is in the closed state, the door body generates an initial pressure on the pressure sensor. When the door body is pressed, a small displacement will occur, so that the pressure received by the pressure sensor is greater than the above initial pressure, thereby driving the mechanism to cooperate to achieve the purpose of pressing and opening the door.

[0003] However, in the process of kitchen appliance production and manufacturing, due to problems such as equipment, assembly or aging of the door seal, it is easy to cause the door body to generate a displacement exceeding the tolerance. In the closed state of the door, it is possible that the door body cannot touch the pressure sensor, that is, the pressure sensor does not receive pressure or the pressure received is less than the above initial pressure.

[0032] In order to make the purpose, technical solutions and advantages of the disclosure of the embodiments of the present application clearer and more understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0033] The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0034] Please refer to Figures 1-6 , a pressure sensing mechanism provided by an embodiment of the present utility model includes a pressure sensing component 1 and a magnetic member. The pressure sensing component 1 and the magnetic member are fixedly arranged on a kitchen appliance. The kitchen appliance includes a door body and a box body, and the door body and the box body are rotatably connected. The pressure sensing component 1 is arranged on a target structure 3, and the target structure 3 is any one of the door body and the box body; the magnetic member includes a first magnetic member 21 and a second magnetic member 22. The first magnetic member 21 is fixedly arranged on the pressure sensing component 1, and the second magnetic member 22 is arranged on another structure 4. The first magnetic member 21 and the second magnetic member 22 are arranged corresponding to each other, and the magnetic poles of the first magnetic member 21 and the second magnetic member 22 are the same; the other structure 4 is a structure in the door body and the box body except the target structure 3.

[0035] In a specific embodiment, as Figures 1-3 shown, taking the kitchen appliance as a refrigerator, the target structure 3 as the box body, and the other structure 4 as the door body as an example, the pressure sensing component 1 can be arranged on the top of the box body, the first magnetic member 21 is arranged inside the pressure sensing component 1, and the second magnetic member 22 is arranged on the top of the door body, opposite to the pressure sensing component 1. The pressure sensing component 1 can be a pressure sensor, and the first magnetic member 21 and the second magnetic member 22 can be magnets.

[0036] In practical applications, the kitchen appliance can open the door by pressing the door body. Since the magnetic poles of the first magnetic member 21 and the second magnetic member 22 are the same, that is, there is a repulsive force between the first magnetic member 21 and the second magnetic member 22. When the door body is in the normal closed state, the door body generates a pressure on the pressure sensing component 1. At this time, the pressure received by the pressure sensing component 1 can be equal to the sum of the door body pressure and the repulsive force. In the prior art, when the door body is not normally closed, for example, due to production and assembly problems, aging of the door body seal, etc., when the door body is closed, it cannot touch the pressure sensing component 1, and the pressure sensor does not sense the pressure or the sensed pressure is less than the sum of the door body pressure and the repulsive force. However, for the structure in this application, based on the repulsive force between the first magnetic member 21 and the second magnetic member 22, the pressure sensing component 1 can still sense the pressure, improving the pressure sensing sensitivity in various situations, and this pressure can be equal to the repulsive force. Thus, when pressing the door body, the door body generates a small displacement towards the box body direction, and when the pressure received by the pressure sensing component 1 is greater than the above-mentioned repulsive force, the door can be opened normally, avoiding insufficient pressing stroke caused by the above problems resulting in the door body not being able to be normally pressed open. At the same time, it can also improve the fault tolerance rate of the production and manufacturing of the kitchen appliance and reduce the manufacturing cost.

[0037] Optionally, as Figures 4-6As shown in the figure, the pressure sensing mechanism includes a sensing member 11. The sensing member 11 protrudes from the target surface. The first magnetic member 21 is fixedly arranged inside the sensing member 11, and the second magnetic member 22 is embedded inside another structure 4. The target surface is the surface of the target structure 3 facing the other structure 4. When the door body is in the closed state, the sensing member 11 is arranged opposite to the second magnetic member 22. Specifically, an opening is provided on one side of the target structure 3 facing the other structure 4, and the sensing member 11 passes through the opening. The sensing member 11 can be the thimble of a pressure sensor, and the pressure sensing assembly 1 can receive the pressure from the door body through the sensing member 11.

[0038] Specifically, when the door body is in the closed state, the sensing member 11 protrudes from the target surface by a first preset length. When the door body is in the closed state and in the pressed state, the sensing member 11 protrudes from the target surface by a second preset length, and the second preset length is less than the first preset length. The first preset length and the second preset length can be set according to actual application requirements. After the door body is pressed, the pressure received by the sensing member 11 is greater than the pressure received when the door body is closed and not pressed, causing the sensing member 11 to contract towards the door body direction, and the length protruding from the door body becomes shorter.

[0039] Optionally, the pressure sensing mechanism further includes a sensing main body structure 12. The sensing main body structure 12 is fixedly arranged inside the target structure 3. The sensing member 11 is connected to the sensing main body structure 12 through an elastic member, and both ends of the elastic member are fixedly connected to the sensing member 11 and the sensing main body structure 12 respectively. Specifically, the elastic member can be a spring.

[0040] In the embodiment of this specification, when the door body is in the normal closed state, based on the repulsive force between the first magnetic member 21 and the second magnetic member 22, the sensing member 11 retracts towards the inside of the sensing main body structure 12, and the elastic member compresses and deforms. At this time, the pressure received by the pressure sensing assembly 1 can be equal to the sum of the door body pressure and the repulsive force. In the case of abnormal closing of the door body, based on the repulsive force between the first magnetic member 21 and the second magnetic member 22, it can still cause the sensing member 11 to retract towards the inside of the sensing main body structure 12, and the elastic member compresses and deforms. At this time, the pressure collected by the pressure sensing assembly 1 can be equal to the repulsive force. Thus, when pressing the door body, the door body generates a small displacement towards the box body direction, making the pressure received by the pressure sensing assembly 1 greater than the above-mentioned repulsive force, and the door can be normally pressed and opened. By embedding magnets inside the door body and the sensing member 11, the pressing tolerance is eliminated by using the repulsive force between the magnets, avoiding insufficient pressing stroke caused by the above problems and resulting in the door body being unable to be normally pressed and opened.

[0041] In some embodiments, a protruding structure (not shown) is provided on one side of the other structure 4 facing the target structure 3. The protruding structure is disposed opposite to the sensing member 11, and the second magnetic member 22 is embedded inside the protruding structure. Specifically, taking the other structure 4 as a door body as an example, the protruding structure is provided on the side of the door body facing the cabinet body, and is disposed opposite to the pressure sensing assembly 1 on the cabinet body. By providing the second magnetic member 22 inside the protruding structure, the pressure sensing of the pressure sensing assembly 1 can be made more sensitive, thereby increasing the success rate of pressing to open the door.

[0042] As can be seen from the technical solutions provided in the embodiments of this specification above, a pressure sensing mechanism in this specification includes a pressure sensing assembly and a magnetic member. The pressure sensing assembly and the magnetic member are fixedly provided on a kitchen appliance. The kitchen appliance includes a door body and a cabinet body, and the door body and the cabinet body are rotatably connected. The pressure sensing assembly is provided on a target structure, and the target structure is any one of the door body and the cabinet body; the magnetic member includes a first magnetic member and a second magnetic member. The first magnetic member is fixedly provided on the pressure sensing assembly, and the second magnetic member is provided on another structure. The first magnetic member and the second magnetic member are correspondingly arranged, and the magnetic poles of the first magnetic member and the second magnetic member are the same; the other structure is a structure other than the target structure among the door body and the cabinet body. Thus, based on the correspondingly arranged first magnetic member and second magnetic member, the pressure sensing sensitivity of the pressure sensing assembly can be improved, and situations such as the door body not fitting properly, which may cause the door body to not open normally, can be avoided, and the success rate of pressing to open the door can be increased. In addition, by means of the above pressure sensing mechanism with a magnetic member, situations where the door body cannot open normally due to the door body not fitting properly can be avoided, the error tolerance rate of electrical appliance manufacturing can be increased, and the manufacturing cost can be reduced.

[0043] The embodiment of the present application further provides an opening mechanism, which includes a driving mechanism (not shown) and the above pressure sensing mechanism. The driving mechanism is fixedly provided on the target structure, and the driving mechanism is electrically connected to the pressure sensing mechanism.

[0044] Optionally, the driving mechanism includes a driving motor, a transmission structure, and an ejecting structure. The driving motor is fixedly provided on the target structure. One end of the transmission structure is fixedly connected to the driving motor, and the other end of the transmission structure is connected to one end of the ejecting structure; when the door body is in a closed state, the other end of the ejecting structure contacts the other structure. Specifically, when the door body is in a closed state, based on the pressure data received by the pressure sensing mechanism, under the drive of the driving motor, the transmission structure is driven to move, so that the ejecting structure pushes the door body open. The specific shape and structure of the ejecting structure can be set according to actual application requirements, such as rod-shaped, block-shaped, etc.

[0045] The embodiment of the present application further provides a kitchen appliance, which includes the above opening mechanism. Specifically, the kitchen appliance can be any appliance with a door body suitable for the kitchen, such as a refrigerator, an oven, a microwave oven, etc.

[0046] Optionally, the kitchen appliance further includes a control mechanism (not shown), and the control mechanism is electrically connected to the pressure sensing mechanism and the door opening mechanism respectively. Specifically, the control mechanism receives the pressure data sent by the pressure sensing mechanism, and when the pressure data is greater than the pressure threshold, controls the door opening mechanism to perform the door opening operation. The pressure threshold can be set according to actual application requirements. For example, it can be the magnitude of the repulsive force between the first magnetic member and the second magnetic member.
