With the popularization of refrigeration equipment in daily life of people, more and more people begin to use refrigeration equipment such as refrigerators to store perishable foods such as vegetables and fish.

Taking a refrigerator as an example, the interior space of a conventional refrigerator is largely divided into a freezing chamber and a refrigerating chamber. Cold air heat-exchanged with the evaporator directly flows into the freezing chamber, and the temperature of about-18 ℃ is maintained. The cold air flowing into the freezing chamber or the cold air exchanging heat with the evaporator in the refrigerating chamber is kept at 0-7 ℃. The upper part of the evaporator is provided with a cold air circulating fan to forcibly blow the low-temperature air cooled by the evaporator into the freezing chamber.

The freezing chamber and the refrigerating chamber are divided by a partition plate portion at upper and lower sides. A freezing chamber cold air circulation passage and a refrigerating chamber cold air circulation passage are formed in the partition plate portion. The cold air, which is raised in temperature while flowing through the freezing chamber and the refrigerating chamber, flows to the evaporator through the freezing chamber cold air circulation path and the refrigerating chamber cold air circulation path, and circulates. The back of the refrigerating chamber is provided with a cold air discharge pipeline for directly discharging the refrigerant which exchanges heat with the evaporator to the refrigerating chamber. The cool air flowing into the inside of the refrigerating chamber is convected. When the cool air is convected, the cool air flows into the storage chamber to cool the storage chamber.

In order to facilitate the taking, one or more drawers are generally disposed in a storage chamber (such as a refrigerating chamber) of the refrigerator, when a user needs to take a stored article, the user can pull out the drawer and take the required stored article, and after the taking action is completed, the user can push the drawer back into the storage chamber so as to complete the whole taking process.

The cool air formed during heat exchange in the evaporator flows into the refrigerating chamber along the cool air discharging pipeline and then flows into the drawer. The cool air cools the foods such as fruits or vegetables in the drawer and then flows into the refrigerating chamber again.

In the related art, as drawers in the refrigerator are all designed in an open type, gaps are formed between the drawers and the cover plate, the tightness is poor, and cold air circulates through the gaps. At this time, the moisture of the vegetables circulates together with the cool air, so that the vegetables in the drawer cannot be kept in a closed state, the mutual smell of the stored matters in the storage chamber is easily caused, the freshness of the vegetables is reduced, bacteria breeding and bad smell growth are seriously caused, and the food sanitation is influenced.

In order to solve the above-mentioned problems, some sealing schemes have been proposed in the related art, for example, a plurality of extension springs are provided at the lower portion of the tray in a vertically downward direction, the ends of the extension springs are connected to a closing cap, the closing cap closes the open top surface of the drawer, and the extension springs elastically support the closing cap. The tray has 2 coupling parts combined to two sides, and the back of the drawer contacts with the end of the coupling part bent below the closing cover to apply pressure to the coupling part to push the coupling part. The pushed coupling member rotates due to the coupling to the hinge of the tray. The other end of the coupling member is coupled to the top surface of the closure. The closure is thus pushed downwards when the coupling part is rotated. When the vegetable preservation container is completely contained in the refrigerator, the sealing cover is closely contacted with the top surface of the drawer to seal the drawer. However, since the sealing cover is elastically supported by means of a plurality of extension springs, when the connecting part presses the sealing cover, if the stress is uneven, the elastic deformation amounts generated by the extension springs at different positions are different, so that the sealing cover is inclined, namely the sealing cover is in an unstable state, the phenomenon that the top surface part of the drawer and the sealing cover are in a gap with each other is easy to occur, and the sealing effect is poor is also caused.

Other sealing arrangements have been proposed in the related art, for example, in which a rail is provided in the case along which the cover can be moved between a closed position and an open position. Therefore, the movement track of the cover plate in the storage chamber can be limited through the track, the opening of the drawer can be accurately covered by the cover plate in the closed position, and the opening can be smoothly opened by the cover plate in the open position without affecting the movement stroke of the drawer. However, this solution is mainly pressed against and covers the opening of the drawer by the weight of the cover plate, which during movement along the rail towards the open position requires the overcoming of a greater weight, generally requiring the addition of power means. When the cover plate is closed, the drawer is pressed by the gravity of the cover plate, so that the sealing effect is poor. In addition, in order to move accurately, the track needs to be manufactured accurately, otherwise, the problem of clamping and deflection easily occurs. The scheme has the problems of complex structure and high cost due to the need of additionally adding a power device and high track manufacturing precision requirement.

When drawer 201 advances to the close-up position of refrigerated compartment 103, drawer 201 comes into contact with push plate 205, such that as drawer 201 moves, push plate 205 moves cover 203 together, and cover 203 moves downward and rearward until it reaches the closed position, as cover 203 is restrained by the linkage assembly.

Referring to fig. 2 to 4, it will be appreciated that the drawer 201 is provided with a protrusion 206, the protrusion 206 being located at one end of the drawer 201 near the push plate 205, the protrusion 206 protruding from a side wall of the drawer 201 for abutting the push plate 205. By providing the protruding portion 206, the drawer 201 is facilitated to be engaged with the push plate 205, and accuracy of engagement is improved.

Referring to fig. 4, it can be understood that the protruding portion 206 surrounds the left, right and rear side walls of the drawer 201, thereby having an effect of reinforcing the strength of the side walls of the drawer 201, so that the drawer 201 is not easily deformed, thereby making the opening edge of the drawer 201 closely contact with the cover plate 203, preventing a gap from being easily formed, and improving the sealing effect.

Referring to fig. 4 to 7, it will be appreciated that each unit assembly 410 includes a first link 402 and a second link 403, the first link 402 and the second link 403 being rotatably coupled, the first link 402 being rotatably coupled to the mounting plate 202, the second link 403 being rotatably coupled to the cover plate 203. Each unit assembly 410 includes a first link 402 and a second link 403, and under the cooperation of the reset member, more degrees of freedom of movement can be achieved, so that the cover 203 in the opened state of the drawer 201 is in a relatively stable state, and the cover 203 in the opened and closed state of the drawer 201 is also in a relatively stable state. That is, the link assembly of the embodiment of the present invention can achieve bistable state, can improve stability in the opened and closed state of the drawer 201, and can reduce friction of the cover 203 applied to the drawer 201 when the drawer 201 is opened, compared to a monostable structure having only a single link.

It will be appreciated that pushing the drawer 201 into the refrigerated compartment 103 from the refrigerator, the rear end of the drawer 201 begins to abut against the push plate 205, and as the drawer 201 continues to slide backward, the push plate 205 drives the cover 203 to move, the plurality of first links 402 and the second links 403 of the link assembly begin to rotate following the cover 203, the restoring member begins to elastically deform, and the restoring member generates an upward force on the second links 403 at the front side of the second links 403. When the cover 203 moves downward to close the opening of the drawer 201, the restoring member generates a force on the second link 403 at the rear side of the second link 403, so that the link assembly can press the cover 203, thereby maintaining the cover 203 in a closed state.

It will be appreciated that the unit assembly 410, by having the first link 402 and the second link 403, the first link 402 and the second link 403 have three hinge points, so that the link assembly has a critical state in which the force generated by the restoring member is converted to a transitional state in which the force acts on the front side of the second link 403 is converted to act on the rear side of the second link 403. The bistable state of the link assembly is switched by switching the direction of the force of the return element on the second link 403.

Referring to fig. 4 to 7, it can be appreciated that one implementation of the link assembly is to change the direction of the force applied to the second link 403 by the elastic member. That is, the restoring member includes a first elastic member 408 and a second elastic member 409, the first connecting rod 402 is connected to the mounting plate 202 through a first shaft 501, the first connecting rod 402 is connected to the second connecting rod 403 through a second shaft 502, the first elastic member 408 is sleeved on the first shaft 501, and the second elastic member 409 is sleeved on the second shaft 502.

Referring to fig. 5, it can be understood that the drawer 201 is initially contacted with the push plate 205, and the first and second links 402 and 403 are maintained in a state of being inclined toward the front lower angle by the gravity of the cover 203, the elastic force of the first and second elastic members 408 and 409, so that the cover 203 is in a relatively stable state. Wherein the direction of the force applied to the cover 203 by the second link 403 is upward.

Referring to fig. 6, it can be understood that the drawer 201 pushes the push plate 205 to move, the first link 402 and the second link 403 rotate clockwise as shown by the cover 203, and the first link 402 is inclined toward the front lower corner due to the gravity of the cover 203 and the elastic force of the first elastic member 408 and the second elastic member 409. The angle of rotation of the second link 403 in the clockwise direction is greater than the angle of rotation of the first link 402, that is, the angle of rotation of the end of the second link 403 near the cover plate 203 is greater than the angle of rotation of the end near the first link 402, so that the end of the second link 403 near the cover plate 203 can rotate from the front side to the rear side at the end of the first link 402 of the second link 403, thereby realizing bistable switching.

Referring to fig. 7, it will be appreciated that the fresh keeping assembly 102 is in a closed state, and the cover 203 is crimped to the drawer 201 to close the opening of the drawer 201. After the second link 403 rotates to a certain setting position, the drawer 201 continues to slide backward, the first link 402 rotates around the first rotation shaft 501 and compresses the first elastic member 408, and the action of closing the drawer 201 is completed after the drawer 201 reaches the stop position, at this time, both the first elastic member 408 and the second elastic member 409 are in a compressed state. The included angle A1 between the connection line of the two rotation center points of the first link 402 and the upper surface of the drawer 201 is smaller than 90 °, that is, the included angle A1 between the connection line of the two rotation center points of the first link 402 and the drawer 201 toward the front side direction is smaller than 90 °, and at this time, the first link 402 is inclined toward the rear lower corner. An included angle A2 between a line connecting two rotation center points of the first link 402 and a line connecting two rotation center points of the second link 403 is smaller than 180 °, that is, an included angle between the first link 402 and the second link 403 faces in a rear side direction, and at this time, the second link 403 is inclined toward a rear lower angle. Since the first elastic member 408 and the second elastic member 409 are both in a compressed state, the second link 403 is caused to rotate counterclockwise, thereby pressing the cover 203 downward, and the cover 203 maintains a relatively stable state under the force of the drawer 201.

It will be appreciated that when drawer 201 is withdrawn, cover 203 is subject to the force of the linkage assembly and the static friction of drawer 201, and starts to move from the position shown in fig. 7 to the position shown in fig. 6, and when A2 is greater than 180 °, cover 203 moves upward under the action of first elastic member 408 and second elastic member 409, cover 203 is separated from the edge of the opening on drawer 201, and cover 203 and drawer 201 do not generate any friction, so that they do not scratch each other. The first elastic member 408 and the second elastic member 409 rotate the first link 402 and the second link 403 and move the cover 203 upward until the cover 203 reaches a defined position to stop the movement.

It will be appreciated that the mounting plate 202 is provided with a first stop (not shown) for stopping the first link 402, i.e. the first stop is adapted to prevent the first link 402 from rotating under the action of the first elastic member 408, so that the first link 402 is maintained in a relatively stable state.

It will be appreciated that the mounting plate 202 is provided with a second stop (not shown) for stopping the second link 403, i.e. the second stop is adapted to prevent the second link 403 from rotating under the action of the second elastic member 409, so that the second link 403 is maintained in a relatively stable state.

Referring to fig. 2 and 3, it can be understood that the drawer 201 is provided with a supporting portion 207, the supporting portion 207 is used for supporting the cover plate 203, and the supporting portion 207 is provided at an end of the drawer 201 remote from the push plate 205 and above the accommodating chamber 204. By providing the support portion 207, the contact area with the cover plate 203 is increased, so that the stress is more uniform, and the deformation resistance of the drawer 201 is enhanced.

Referring to fig. 4, it can be understood that the middle part of the cover plate 203 is provided with an upward boss 407, the boss 407 forms a concave and convex structure, that is, the lower side of the boss 407 is concave upward, the upper side of the boss 407 is convex upward, food in the drawer 201 can be avoided by providing the boss 407, and the boss 407 can also enhance the strength of the cover plate 203, so that the cover plate 203 is not easy to deform, and the sealing performance is improved.
