Description
Technical Field
[0001] This application relates to the technical field of electrical appliances, and particularly to refrigeration equipment. Background Art
[0002] Taking a refrigerator as an example of refrigeration equipment, in order to facilitate pulling out the entire storage space to access food, the refrigeration equipment is usually configured with a drawer door, that is, part of the freezer or refrigerator compartment exists in the form of a drawer. The drawer door can be fully pulled out, enabling users to easily view and access all the food, especially items stored deep in the refrigerator.
[0003] Generally, the drawer door is slidably connected to the cabinet through a slide rail. The opening or closing of the drawer door is achieved by the movement of the slide rail. When the door body is closed, the door body is locked by the spring of the slide rail itself. However, since the support method of the drawer door mainly comes from the slide rail, the spring of the slide rail itself needs to overcome the load gravity of the door body and the drawer interior, the friction brought by the long-term use and wear of the slide rail, and the resistance caused by the frosting inside the metal guide rail of the slide rail after refrigeration in the freezer. Once these resistances are greater than the elastic force of the spring of the slide rail itself, the door body cannot be tightly closed. Therefore, the drawer door of the existing refrigeration equipment has the problem that the door body cannot be tightly closed after long-term use, which affects the refrigeration performance of the refrigeration equipment. Summary of the Utility Model

The cabinet includes a refrigeration space with an opening; the door body is slidably connected to the cabinet and covers the opening, and the door body is configured to be able to move relative to the cabinet on a closing path; the locking assembly includes a magnetic member and a switch magnetic absorber. The magnetic member is installed on the door body, and the switch magnetic absorber is installed on the cabinet and has a magnetic adsorption state of generating magnetic force and a shutdown state of not generating magnetic force.

[0006] In one embodiment, the switch magnetic absorber is configured to be triggered to switch to the magnetic adsorption state when the door body is at a set position on the closing path.

[0015] In the refrigeration device provided in the above solution, by providing a magnetic member on the door body and a switch magnetic attracting member with a magnetic attracting state and a shutdown state on the box body, the magnetic attracting member in the magnetic attracting state is used to attract the magnetic member in the door body, so that the magnetic force between the two drives the door body and the box body to be locked, achieving the effect of closing the door, avoiding the problem that the door body is not tightly closed and affecting the refrigeration efficiency. At the same time, the switch magnetic attracting member can also be switched to the shutdown state to avoid the magnetic force between the switch magnetic attracting member and the magnetic member from affecting the opening of the door body.

[0029] Refer to Figure 1 , Figure 1 FIG. shows a schematic structural diagram of a refrigeration device 100 in an embodiment of the present application. A refrigeration device 100 provided in an embodiment of the present application can be a refrigerator as shown in Figure 1 or other devices with refrigeration functions, without limitation. The refrigeration device 100 includes a box body 110, a door body 120, and a locking assembly 130. Among them, the box body 110 includes a refrigeration space 111 with an opening, and the refrigeration space 111 is used to hold items to be refrigerated. As shown in Figure 1 , the door body 120 is slidably connected to the box body 110 and covers the opening. The door body 120 is configured to be able to move relative to the box body 110 on opening paths and closing paths in opposite directions, so that when the door body 120 is in the open position, the opening is opened to take and place food ingredients, and when the door body 120 is in the closed position, the door body 120 and the box body 110 jointly enclose a closed refrigeration space 111.
[0030] Combined Figure 2 As shown Figure 2 As shown, a partial cross-sectional schematic diagram of a refrigeration device 100 in an embodiment of the present application is shown. The locking assembly 130 includes a magnetic member 131 and a switch magnetic attracting member 132. The magnetic member 131 is installed on the door body 120. Exemplarily, the magnetic member 131 can be a magnet, a magnetic metal, etc. The switch magnetic attracting member 132 is installed on the box body 110, and the switch magnetic attracting member 132 has a magnetic attracting state in which magnetic force is generated and a shutdown state in which no magnetic force is generated. When the switch magnetic attracting member 132 is in the magnetic attracting state, the switch magnetic attracting member 132 attracts the magnetic member 131, so that when the door body 120 is closed, a force is provided to make the door body 120 continue to move in the direction of the box body 110 to lock the door body 120 and the box body 110, thereby avoiding the problem that the door body 120 is not tightly closed.
[0031] In one embodiment, the switch magnetic attracting member 132 is an electromagnet. When the switch magnetic attracting member 132 is energized, it is in the magnetic attracting state, and when the switch magnetic attracting member 132 is de-energized, it is in the shutdown state. In other embodiments, the switch magnetic attracting member 132 can also adopt other structures, for example, by arranging a magnetic shielding structure outside the permanent magnet to achieve two states of magnetic attraction and non-magnetic attraction, which is not limited.
[0032] In one embodiment, the switch magnetic attracting member 132 is configured to be triggered to switch to the magnetic attracting state when the door body 120 is at a set position on the closing path. When the door body 120 is in the open state, or when the door body 120 is in the closing process but the distance between the door body 120 and the box body 110 is relatively far, the adsorption effect of the switch magnetic attracting member 132 on the magnetic member 131 is small. Triggering the switch magnetic attracting member 132 when the door body 120 is at the set position can avoid the switch magnetic attracting member 132 always remaining in the magnetic attracting state and consuming energy.
[0033] Combined Figures 2 to 5 As shown, in one embodiment, the locking assembly 130 includes a push rod 133. The push rod 133 is partially located on the closing path of the door body 120. When the door body 120 moves along the closing path until the door body 120 is at the set position, the door body 120 abuts against the push rod 133. At this time, the push rod 133 is stressed and triggers a position signal for triggering the switch magnetic attracting member 132. In some embodiments, the push rod 133 can be set as a deformable structure or material. When the push rod 133 deforms, an internal position signal is triggered, and the switch magnetic attracting member 132 is triggered by using this position signal to switch it to the magnetic attracting state.
[0034] Such as Figure 3 And Figure 4As shown, in one embodiment, the push rod 133 can extend and contract in a direction parallel to the direction of the closing path, and the telescopic path of the push rod 133 partially overlaps with the closing path of the door body 120. Specifically, as Figure 3 shown, when the push rod 133 is in the extended state, the part of the push rod 133 protruding from the cabinet 110 is located on the closing path of the door body 120, as Figure 4 shown, when the push rod 133 is in the contracted state, the push rod 133 does not protrude from the cabinet 110 and is in the extending direction of the closing path of the door body 120.
[0035] As Figure 2 shown, during the closing process of the door body 120, the push rod 133 is initially in the extended state. When the door body 120 moves along the closing path until the door body 120 is in the set position, the door body 120 abuts against the push rod 133. At this time, the door body 120 will have a thrust force to drive the push rod 133 to contract, thereby triggering the position signal for triggering the switch magnetic part 132, and the switch magnetic part 132 is configured to be triggered to switch to the magnetic adsorption state when the push rod 133 is abutted. In other embodiments, a position sensor triggered at the set position can also be provided in the slide rail assembly where the door body 120 is slidably connected to the cabinet 110, and the switch magnetic part 132 is triggered after receiving the position signal of the position sensor.
[0036] As Figures 2 to 5 shown, in one embodiment, the locking assembly 130 further includes a driving member 134. The driving member 134 is used to drive the push rod 133 to extend and contract, and the driving member 134 is configured to be triggered when the push rod 133 is stressed and drive the push rod 133 to contract. The door body 120 has a force to drive the push rod 133 to contract on the push rod 133. In this embodiment, the driving member 134 is a driving motor. At the same time, the force obtained by the driving member 134 and the driving member 134 starts to drive the push rod 133 to contract, which will give a position signal to the switch magnetic part 132, so that the switch magnetic part 132 is triggered after receiving the position signal of the position sensor. In practical applications, a control board can be set to receive the signal and control the opening or closing of the driving member 134 and the switch magnetic part 132.
[0037] As Figure 1 shown, in one embodiment, the refrigeration device 100 further includes a trigger member 140. The switch magnetic part 132 is controlled by the trigger member 140, and when the trigger member 140 is triggered, the switch magnetic part 132 switches to the shutdown state to prevent the switch magnetic part 132 from magnetically adsorbing the magnetic part 131 and affecting the opening of the door body 120.
[0038] As Figure 1As shown, in one embodiment, the refrigeration device 100 further includes a trigger member 140. The driving member 134 is controlled by the trigger member 140. When the trigger member 140 is triggered, the driving member 134 drives the push rod 133 to extend, so as to push the door body 120 to move on the opening path through the push rod 133, thereby realizing the boosting effect during the opening process.
[0039] As Figure 1 shown, other doors that are usually on the same plane as the outer end surface of the door body 120 are usually provided in the refrigeration device 100. For the aesthetic appearance of the refrigeration device 100, there is usually only a small gap between the door body 120 and the other doors, such as Figure 1 and Figure 2 shown, in one embodiment, a handle groove 121 is opened at the top or bottom end of the door body 120. It can be understood that when the other door is above the door body 120, the handle groove 121 is opened at the top end of the door body 120, and when the other door is below the door body 120, the handle groove 121 can also be opened at the bottom end of the door body 120. As Figure 2 shown, when the push rod 133 is in the extended state, the moving distance of the door body 120 is not less than the minimum distance between the handle groove 121 and the end surface of the door body 120 facing away from the cabinet 110, so as to facilitate the user to open the door body 120 through the handle groove 121. Preferably, when the telescopic rod is in the extended state, most or completely of the opening of the handle groove 121 protrudes from the plane of the outer end surface when the door body 120 is in the closed state, so as to stagger the other doors above and below the door body 120, and facilitate the user to pull the door body 120 through the handle groove 121.
[0040] In one embodiment, the trigger member 140 is connected to the cabinet 110 and is arranged facing the door body 120, and the trigger member 140 is configured to be triggered when the door body 120 continues to move towards the cabinet 110 in the extension direction of the closing path. It can be understood that when the door body 120 is in the fully closed state, due to the sealing ring for sealing the gap between the door body 120 and the cabinet 110, when an external force is applied to the door body 120, the door body 120 still has the possibility of continuing to move a small distance towards the cabinet 110 in the extension direction of the closing path, and it compresses the sealing ring to realize the movement of the door body 120, but it does not affect the fact that the door body 120 is in the fully closed state before moving. In actual use, only by adjusting the trigger sensitivity of the trigger member 140 to be triggered when the door body 120 moves a small distance due to an external force, the opening requirement of the user can be known through the trigger member 140.
[0041] For the refrigeration device 100 provided in the above solution, when in use:
[0042] When the door body 120 needs to be closed: The user pushes the door body 120 along the closing path. When the door body 120 reaches the set position, the door body 120 abuts against the push rod 133 and applies a force to drive the push rod 133 to shorten. This force will cause effects such as load changes on the driving member 134. The driving member 134 itself will recognize this change and automatically start to drive the push rod 133 to shorten. At the same time, it will feedback a signal to the switch magnetic part 132 to switch it to the magnetic adsorption state that generates magnetism, so as to lock the door body 120 and the box body 110 through the magnetism between the switch magnetic part 132 and the magnetic part 131, achieving the door closing effect.
[0043] When the door body 120 needs to be opened: The user presses the door body 120, so that the door body 120 continues to move towards the box body 110 in the extending direction of the closing path, and triggers the trigger part 140 arranged towards the door body 120. After receiving the electrical signal of the trigger part 140, the driving member 134 starts to drive the telescopic rod to extend. At the same time, it will feedback a signal to the switch magnetic part 132 to switch it to the shutdown state where no magnetism is generated. As the telescopic rod extends, the opening of the handle groove 121 provided on the door body 120 mostly or completely protrudes from the plane of the outer end surface when the door body 120 is in the closed state, so as to stagger with other doors above and below the door body 120, facilitating the user to pull the door body 120 through the handle groove 121.
[0044] In the refrigeration device 100 provided in the above solution, by arranging the magnetic part 131 on the door body 120 and arranging the switch magnetic part 132 with a magnetic adsorption state and a shutdown state on the box body 110, the switch magnetic part 132 in the magnetic adsorption state is used to adsorb the magnetic part 131 inside the door body 120, so that the magnetism between the two drives the door body 120 and the box body 110 to be locked, achieving the door closing effect, avoiding the problem that the door body 120 is not tightly closed and affecting the refrigeration efficiency. At the same time, the switch magnetic part 132 can also be switched to the shutdown state to avoid the magnetism between the switch magnetic part 132 and the magnetic part 131 from affecting the opening of the door body 120.
[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0046] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
