Description

Technical Field

[0001] The present application relates to the field of electrical equipment technology, and in particular to refrigeration equipment. Background Art

[0002] As consumers' demands for storage functions of refrigeration equipment, such as refrigerators, become increasingly diversified, the design of refrigeration equipment tends to provide more sophisticated storage solutions. At present, the multi-drawer design of refrigerators can adapt to the specific storage needs of different foods, such as rapid cooling, fresh-keeping functions, and multi-temperature and multi-humidity zone control to optimize the storage conditions of food, extend its freshness and shelf life, meet users' specific needs for classified storage of different foods, and improve storage efficiency and convenience. Refrigeration equipment also includes a door body, the main function of which is to isolate the heat exchange between the inside of the refrigeration equipment and the external environment, and ensure the stability of the internal refrigeration effect.

[0003] In normal use, the operation process of users storing and accessing items in the refrigerator usually includes: opening the refrigerator door, pulling out the required drawer, taking and placing items, then closing the drawer, and finally closing the refrigerator door. In this process, the frequent opening and closing of the drawer and the door will cause a large amount of cold air to exchange heat with the outside air, thereby causing the temperature inside the refrigerator to rise in a short time, which not only affects the designed refrigeration effect of the refrigerator, but may also have an adverse effect on the preservation quality of food. Taking the middle drawer of the freezer as an example, the time interval from opening the door to fully opening the drawer is about 3 seconds. In this short 3 seconds, the lower drawer of the freezer is directly exposed to the outside air. Taking a conventional freezer drawer as an example, its size is 750mm×350mm×250mm, the room temperature is set to 30℃, and the internal temperature of the drawer is maintained at -18℃. According to the heat conduction calculation formula, it can be calculated that the heat dissipation in this process is about 30 joules.

[0030] In one embodiment of the present application, a refrigeration device 100 is provided, and the refrigeration device 100 may be a refrigerator, a freezer, or other equipment with a refrigeration function. The refrigeration device 100 includes an inner liner and a door body 110, wherein the inner liner is provided with an open refrigeration space, the door body 110 is movably connected to the inner liner, and the door body 110 covers the inner liner and covers the open opening, so that when the door body 110 covers the inner liner, the door body 110 and the inner liner together enclose a closed refrigeration space.

[0031] The refrigeration device 100 further includes a linkage drawer 120 and a connection assembly 130. The linkage drawer 120 can be connected to the inner container and can move in the same direction as the door body 110 to be pushed into or pulled out of the refrigeration space. Figure 1 , Figure 1 The schematic diagram of the structure of the door body 110, the linkage drawer 120 and the connection assembly 130 in the refrigeration device 100 in one embodiment of the present application is shown. The connection assembly 130 is connected to the end surface of the door body 110 facing the refrigeration space and is used to connect the door body 110 and the linkage drawer 120 for synchronous movement.

[0032] Combination Figure 2 As shown, Figure 2 A side schematic diagram of a connection assembly 130 of a refrigeration device 100 in an embodiment of the present application is shown. The connection assembly 130 includes a first clamping member 131 and a second clamping member 132 that are rotatably connected around a rotation axis. The first clamping member 131 is connected to the end surface of the door body 110 facing the linkage drawer 120, and the second clamping member 132 rotates relative to the first clamping member 131 to rotate in a direction such as Figure 3The open state shown and Figure 4 Switch between the clamping states shown, and Figure 2 As shown, when the second clamping member 132 is in the clamping state, the second clamping member 132 abuts against the linkage drawer 120 in the moving direction of the linkage drawer 120 to make the linkage drawer 120 move synchronously with the door body 110, so that when the door body 110 is opened and closed, it can drive the linkage drawer 120 to be pulled out or pushed into the refrigerated space, thereby realizing the linkage between the door body 110 and the linkage drawer 120, simplifying the steps of pulling out the drawer after opening the door, shortening the time required to store items in the drawer, reducing the gap between opening the door and opening the drawer, and reducing the heat transfer between the freezer and the air, thereby reducing the loss of cold air in the refrigerated space and improving the preservation effect in the retrieval link of the refrigerated space.

[0033] In one embodiment, the refrigeration device 100 further includes a common drawer, which can be connected to the inner container in the same direction as the door body 110 to be pushed into or pulled out of the refrigeration space, but is not connected to the door body 110 and is independently pushed and pulled from the linkage drawer 120. In some embodiments, there is a common drawer located below the linkage drawer 120. Figure 5 As shown, when the second clamping member 132 is in the open state, the second clamping member 132 is separated from the linked drawer 120 to prevent the linked drawer 120 from being pulled out with the door body 110 and blocking the retrieval of items in the ordinary drawer below the linked drawer 120, and to prevent the linked drawer 120 from blocking the line of sight and operating space of the ordinary drawer.

[0034] In the above scheme, the drawer is detachably connected to the door body 110 through the connecting component 130 that can switch between the clamping state and the open state, so that the drawer can be driven to be pulled out synchronously when the door body 110 is opened, thereby simplifying the steps of pulling out the drawer after opening the door, shortening the time required for storing items in the drawer, reducing the loss of cold air in the refrigerated space, and improving the preservation effect in the storage and retrieval link of the refrigerated space; it can also drive the linked drawer 120 to be pushed in synchronously when the door body 110 is closed, and can also realize the connection component 130 being switched to the open state by rotating the second clamping member 132, thereby avoiding the linked drawer 120 blocking the retrieval of items in the ordinary drawer below the linked drawer 120 after being pulled out with the door body 110.

[0035] like Figures 2 to 4 As shown, in one embodiment, the connecting component 130 also includes a mounting plate 135, one side of which is connected to the first clamping member 131, and the other side is attached to the end surface of the door body 110 facing the linked drawer 120, so as to facilitate the installation of the connecting component 130 on the door body 110.

[0036] like Figures 2 to 4As shown, in one embodiment, the connecting assembly 130 also includes an elastic member 133, which is coaxially arranged with the rotation axis. The elastic member 133 is connected and acts between the first clamping member 131 and the second clamping member 132, and has a tendency to drive the second clamping member 132 to remain in a clamping state, so that during the opening and closing process of the door body 110, the linked drawer 120 can maintain synchronous movement with the door body 110.

[0037] like Figures 2 to 4 As shown, in one embodiment, the elastic member 133 is a torsion spring, one end of which is fixedly connected to the first clamping member 131, and the other end of which is fixedly connected to the second clamping member 132, so that the first clamping member 131 and the second clamping member 132 are kept in a clamping state. Figure 1 The clamping state shown changes as follows Figure 3 In the open state shown, an external force greater than the elastic force of the elastic member 133 needs to be applied. In other embodiments, the elastic member 133 may be an elastic cord with two ends connected to the first clamping member 131 and the second clamping member 132.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the second clamping member 132 and the first clamping member 131 are both provided with an inclined surface 134 at one end away from the linkage drawer 120, and the two inclined surfaces 134 extend away from each other from the rotation axis to a direction away from the linkage drawer 120, and as shown in FIG. Figure 3 As shown, when the second clamping member 132 is in an open state, the two inclined surfaces 134 are in contact with each other, and the inclination angle of the inclined surface 134 determines the rotatable angle of the first clamping member 131 and the second clamping member 132 relative to each other. In this embodiment, the relative rotation angle of the first clamping member 131 and the second clamping member 132 is 15°-30°. In other embodiments, the angle can be selected according to the required angle when the second clamping member 132 disengages from the abutment groove 121 described below.

[0039] like Figures 2 to 4 As shown, the connecting component 130 is in the shape of a clamp. In other embodiments, the connecting component 130 may also include two rods that can rotate relative to each other, and the rotation axes of the two rods are perpendicular to the end surface of the door body 110 facing the linked drawer 120. The toggle rod is rotated to switch to the clamping state and the open state.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the linkage drawer 120 is provided with an abutment groove 121 with an open top, the abutment groove 121 is located at one end of the top surface of the linkage drawer 120 facing the door body 110, and the connection assembly 130 is located above the linkage drawer 120. Figure 2As shown, when the second clamping member 132 is in the clamping state, the second clamping member 132 can be partially inserted into the abutting groove 121 to abut against the groove wall of the abutting groove 121, so that when the door body 110 and the connecting assembly 130 move synchronously, the linkage drawer 120 can be driven to move accordingly, so that the linkage drawer 120 can be pulled out when the door is opened. Figure 5 As shown, when the second clamping member 132 is in the open state, the second clamping member 132 can be completely moved out of the abutment groove 121, so that the linkage drawer 120 can be separated from the door body 110 and pushed into the refrigerated space without affecting the retrieval of items in the ordinary drawer located below the linkage drawer 120.

[0041] like Figure 2 As shown, in one embodiment, the side wall height h of the abutting groove 121 close to the door body 110 is lower than the side wall height H of the abutting groove 121 away from the door body 110 , so as to facilitate the second clamping member 132 to enter and move out of the abutting groove 121 .

[0042] like Figures 2 to 4 As shown, in one embodiment, the second clamping member 132 includes a clamping portion 1321 having the same length as the first clamping member 131 and an abutting portion 1322 protruding from the clamping portion 1321, and the abutting portion 1322 extends toward the bottom of the abutting groove 121, so that when the second clamping member 132 is in a clamping state, the abutting portion 1322 can be partially inserted into the abutting groove 121 and abut against the groove wall of the abutting groove 121, thereby realizing the abutment of the second clamping member 132 with the linkage drawer 120 and synchronous movement.

[0043] like Figure 2 As shown, in one embodiment, the side wall height h of the abutment groove 121 close to the door body 110 is smaller than the length L of the abutment portion 1322 protruding from the clamping portion 1321, so as to avoid uneven force when the end surface of the linked drawer 120 toward the door body 110 abuts against the first clamping member 131 when the door body 110 moves toward the inner tank to close.

[0044] like Figure 2 As shown, in one embodiment, the distance between the abutment groove 121 and the side wall of the door body 110 and the end face of the linkage drawer 120 facing the door body 110 is A, and the maximum distance between the second clamping member 132 and the end face of the door body 110 facing the linkage drawer 120 is a, wherein A≥a, so that when the door body 110 moves toward the inner tank to close, the end face of the door body 110 facing the linkage drawer 120 abuts against the linkage drawer 120 and drives the linkage drawer 120 to be pushed into the refrigerated space, so that the abutment area between the two during the pushing process is large.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
