Description

Technical Field

[0001] The present invention relates to refrigeration and freezing devices, particularly to a refrigerator. Background Art

[0002] Drawer structures that open and close by pushing and ejecting are widely used in cabinet drawers or furniture drawers. Their structures are similar to the top-pressing structure of a ballpoint pen. Press once and the pen tip extends, press again and the pen tip retracts.

[0003] Some refrigerators can also adopt push-and-eject drawers. A push-and-eject component is arranged between the drawer and the box body. When the drawer is closed, the push-and-eject component locks the drawer to the box body.

[0004] When a user wants to open the drawer, press the front end plate of the drawer backward to move the drawer backward a short distance (such as 5 mm). At the same time, the push-and-eject component unlocks the drawer. The user then stops pushing the drawer backward, and the push-and-eject component will use the elastic force to spring the drawer forward a distance. Then the user can manually pull the drawer forward to open it.

[0005] When closing the drawer, the user pushes the drawer backward to move it to the rear limit position against the elastic force of the push-and-eject component. The user then releases the hand, and the drawer springs forward a short distance under the elastic force of the push-and-eject component to complete the locking of the drawer.

[0006] The particularity of the refrigerator drawer is that there is an upper cover arranged above it. When the drawer is closed, the upper cover tightly seals the upper opening of the drawer. When the drawer is pulled forward to open, the upper cover does not move forward with the drawer. During the movement of the drawer, especially in the initial stage of opening or the final stage of closing, many problems such as poor sealing between the drawer and the upper cover, resistance for the user to push, and noise caused by interference, friction, and collision between the drawer and the upper cover often occur, seriously affecting the user experience. This has also become an important obstacle to the large-scale implementation of push-and-eject drawers in refrigerators. Summary of the Invention

[0007] An object of the present invention is to provide a refrigerator to enhance the sealing performance between a push-and-eject drawer and its upper cover.

[0008] Another object of the present invention is to reduce the noise generated by the collision between the push-and-eject drawer and the upper cover during the closing and spring-back process of the drawer.

[0009] In particular, the present invention provides a refrigerator, comprising a box body and a push-pull type drawer that can be pushed and pulled back and forth inside the box body. When the drawer is closed, it is first pushed backward to a rear limit position, and then rebounds forward by a preset distance under the elastic force and is locked to the box body. The refrigerator further comprises: two slide rails, respectively arranged on the transverse inner side walls of the box body and extending forward and backward, and each slide rail is formed with at least one slope that gradually slopes upward from front to back; and an upper cover, the transverse two ends of which are respectively placed on the two slide rails to cover the upper side opening of the drawer; and during the process that the drawer is pushed backward to the rear limit position, the upper cover moves backward and upward along the slope; after the drawer rebounds forward and is locked, the upper cover moves forward and downward along the slope under its own gravity to closely abut against the drawer.

[0010] Optionally, a buffer stop block is further installed on each slide rail; and when the upper cover moves along the slope to the position of abutting against the drawer, it stops moving under the buffering and blocking of the buffer stop block.

[0011] Optionally, each slide rail has at least one concave portion that is recessed downward, and the rear surface of the concave portion constitutes the slope; and each transverse end portion of the upper cover respectively has at least one mounting post that extends transversely, and each mounting post is located in a concave portion.

[0012] Optionally, the surface of each concave portion is arc-shaped.

[0013] Optionally, each slide rail has two concave portions arranged front and back; and each end portion of the upper cover has two mounting posts arranged front and back.

[0014] Optionally, among the two slopes of each slide rail, the slope of the slope located at the rear side is greater than the slope of the slope located at the front side, so as to make the rear end of the upper cover tilt upward when the upper cover moves backward.

[0015] Optionally, the buffer stop block of each slide rail is arranged in the concave portion located at the front side, so as to be used for blocking the mounting post located at the front part of the upper cover.

[0016] Optionally, above each slide rail, there is a top plate that extends parallel to the slide rail, and each mounting post is located between the slide rail and the top plate; and the top plate is provided with gaps corresponding to the concave portions one by one, so as to make way for the mounting posts when the upper cover is taken out upward.

[0017] Optionally, the refrigerator further comprises: two track plates, respectively installed on the transverse inner side walls of the box body; and each slide rail is formed on the inner surface of a track plate.

[0018] Optionally, the drawer is installed on the two track plates so as to be pushed and pulled back and forth.

[0019] The refrigerator of the present invention is provided with a push-to-open drawer, and the upper cover of the drawer is provided on two slide rails, each of which has a slope that gradually rises from front to back. When the drawer is closed, the drawer is pushed backward to the rear limit position, and the upper cover is pushed backward by the drawer and moves up along the slope. After the drawer rebounds forward under the elastic force to be locked to the box body, the upper cover moves forward and downward along the slope under the action of its own weight, so as to be tightly attached to the drawer. After the drawer is closed, due to the action of the slope, the upper cover still has a tendency to slide forward and downward, thereby better sealing the drawer. In addition, since the upper cover is "movable", when the drawer is closed, the upper cover moves backward with the drawer for a distance, which can avoid the upper cover from generating additional resistance to the drawer's backward movement, making it more labor-saving for the user. The present invention has a simple structure but is very practical. In addition, the number of parts is small, the possibility of failure is small, and the reliability is very high.

[0020] Furthermore, the refrigerator of the present invention is provided with a buffer stop block. When the drawer is closed, the upper cover moves along the slope to a position against the drawer, whereupon the buffer stop block stops the upper cover from moving. The buffer stop block can cushion the impact of the upper cover moving and reduce the impact noise.

[0021] Furthermore, in the refrigerator of the present invention, the slope of the slope on the rear side is greater than the slope of the slope on the front side. The purpose is to make the rear end of the upper cover tilt upward when it moves backward. This can facilitate the subsequent movement forward and downward along the slope more smoothly, so that it can be more closely attached to the drawer and have better sealing performance.

[0038] Next, refer to Figures 1 to 14 to describe the refrigerator according to an embodiment of the present invention. Among them, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. is the orientation or positional relationship marked based on the drawings. Thus, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0039] An embodiment of the present invention provides a refrigerator. The refrigerator according to the embodiment of the present invention can use a vapor compression refrigeration cycle system for refrigeration to provide cooling capacity. The vapor compression refrigeration cycle system includes a compressor, a condenser, an evaporator, a throttling device, and other refrigeration accessories.

[0040] In some embodiments, such as Figure 1 shown, the refrigerator includes a cabinet 10 and a push-pull type drawer 300 that is disposed inside the cabinet 10 and can be pushed and pulled back and forth. A push-pull component is provided between the drawer 300 and the cabinet 10. When the drawer 300 is in the closed state, the push-pull component locks the drawer 300 to the cabinet 10. When the user wants to open the drawer 300, the front panel of the drawer 300 is pressed backward to move the drawer 300 backward a preset distance (such as 5 mm) against the elastic force of the push-pull component. At the same time, the push-pull component unlocks the drawer 300. The user then stops pushing the drawer 300 backward, and the push-pull component uses the elastic force to spring the drawer 300 forward a distance (such as 10 cm), and then the user can manually pull the drawer 300 forward to open it. When the user wants to close the drawer 300, the drawer 300 is first pushed backward to move it against the elastic force of the push-pull component to a rear limit position (at the rear limit position, the drawer 300 cannot be further moved backward). The user then releases the hand, and the drawer 300 rebounds forward a preset distance (such as 5 mm) under the elastic force of the push-pull component to complete the locking of the drawer 300.

[0041] The push-pull type drawer 300 is widely used in cabinet drawers and furniture drawers in the prior art. Therefore, the specific structure of the push-pull structure will not be described in detail here.

[0042] In addition to the drawer 300, the refrigerator may further include other drawers and door bodies, such as the drawer 40 and the door body 20, which will not be described in detail. As Figure 2 shown, the refrigerator may further include two slide rails 110 and an upper cover 400. The two slide rails 110 are respectively disposed on the inner side walls of the cabinet 10 in the horizontal direction (i.e., the left-right direction marked in the figure) and extend forward and backward. Each slide rail 110 forms at least one slope 1121, 1141 that gradually slopes upward from front to back. The horizontal ends of the upper cover 400 are respectively placed on the two slide rails 110 to cover the upper opening of the drawer 300.

[0043] For example Figure 2 two track plates 100, 200 can be provided. The two track plates 100, 200 are respectively installed on the inner side walls of the cabinet 10 in the horizontal direction on both sides. Each slide rail 110 is formed on the inner surface of one of the track plates 100, 200. The drawer 300 can also be installed on the two track plates 100, 200 so as to be pushed and pulled back and forth. As Figure 3 and Figure 9 , the horizontal side walls of the drawer 300 respectively have first slide rails 390 that extend forward and backward, and the two track plates 100, 200 respectively have second slide rails 190 that extend forward and backward. Each second slide rail 190 cooperates with one first slide rail 390 to allow the drawer 300 to be pushed and pulled back and forth.

[0044] During the process of pushing the drawer 300 backward to the rear limit position, the upper cover 400 moves backward accordingly and moves upward along the slopes 1121 and 1141. After the drawer 300 rebounds forward and locks to the box body 10, the upper cover 400 moves forward and downward along the slopes 1121 and 1141 under its own gravity to closely adhere to the drawer 300. In addition, after the drawer 300 is completely closed, due to the action of the slopes 1121 and 1141, the upper cover 400 still has a tendency to slide forward and downward, so as to better seal the drawer 300.

[0045] The drawer described in the embodiment of the present invention is particularly suitable for drawers with dry-wet partition. Drawers used in the dry area or the wet area have relatively high requirements for sealing performance.

[0046] Since the upper cover 400 is "movable", when the drawer 300 is closed, the upper cover 400 moves backward a certain distance along with the drawer 300, which can avoid the upper cover 400 generating additional resistance to the backward movement of the drawer, making it more labor-saving for the user. The structure of the present invention is simple, but the function is very practical. Moreover, the number of parts is small, the possibility of failure is small, and the reliability is very high.

[0047] In some embodiments, a buffer stop block 130 is further installed on each slide rail 110. When the upper cover 400 moves forward and downward along the slopes 1121 and 1141 to the position where it adheres to the drawer 300, it is buffered and blocked by the buffer stop block 130 and stops moving. The buffer stop block 130 can buffer the impact force of the movement of the upper cover 400 and reduce the impact noise. The buffer stop block 130 can be made of materials with relatively large elasticity such as rubber.

[0048] Figures 2 to 4 The figure shows an optional structure of the slide rail 110. Only the structure of the slide rail 110 on the left side is shown in the figure. The slide rail on the right side is symmetrically arranged with the slide rail 110 on the left side.

[0049] As Figures 2 to 4As shown, each slide rail 110 has at least one concave portion 112, 114 that is recessed downward. The rear surfaces of the concave portions 112, 114 form slopes 1121, 1141. Each lateral end portion of the upper cover 400 respectively has at least one mounting post 410, 420 that extends horizontally. The number of the mounting posts 410, 420 is the same as the number of the concave portions 112, 114, and each mounting post 410, 420 is located within one of the concave portions 112, 114. Besides forming the slopes 1121, 1141 on their rear surfaces, another function of the concave portions 112, 114 is to restrict the positions of the mounting posts 410, 420. Unless the mounting posts 410, 420 are subjected to a sufficiently large force to cross over the concave portions 112, 114, the mounting posts 410, 420 will not easily move forward. That is, when the drawer 300 moves forward, even if the upper cover 400 is subjected to the forward frictional force from the top of the drawer 300, it will not easily move forward with the drawer 300, which makes the position of the upper cover 400 relatively stable.

[0050] The surfaces of the concave portions 112, 114 are arc-shaped to facilitate design and processing. Of course, they can also be other curved surfaces. The two ends of the upper cover 400 are only connected to the slide rail 110 through the mounting posts 410, 420, making its contact area with the slide rail 110 very small, which is convenient for cooperation with the slopes 1121, 1141.

[0051] As Figures 2 to 4 shown, each slide rail 110 can have two concave portions 112, 114 arranged front and back, and each end portion of the upper cover 400 has two mounting posts 410, 420 arranged front and back. The front and back ends of the upper cover 400 are respectively supported, and the force is more evenly distributed and the position is more stable.

[0052] Furthermore, as Figures 2 to 4 shown, among the two slopes 1121, 1141 of each slide rail 110, the slope of the slope 1141 located at the rear side is greater than the slope of the slope 1121 located at the front side. For example, when the concave portions 112, 114 are arc-shaped, the radius of the rear concave portion 114 is made smaller than the radius of the front concave portion 112. This makes the slope 1141 at the back steeper, and when the upper cover 400 moves backward, its rear end tilts upward, which is beneficial for it to move more smoothly forward and downward along the slopes 1121, 1141 subsequently, making it fit more closely against the drawer 300 and having better sealing performance.

[0053] As Figure 3 shown, the buffer stop block 130 of each slide rail 110 can be arranged within the front concave portion 112 to be used for blocking the front mounting post 410 of the upper cover 400. Since the upper cover 400 is relatively light in weight, only one buffer stop block 130 is needed to complete the buffering of the upper cover 400, and the structure is simpler.

[0054] The closing process of the drawer 300 in the embodiments of the present invention will be introduced below through Figures 2 to 8 to introduce the closing process of the drawer 300 in the embodiments of the present invention.

[0055] Figures 2 to 4 Figure 7 shows the open state of the drawer 300. At this time, the mounting post 410 is located within the concave portion 112 and is blocked from moving forward by the buffer stop 130. The mounting post 420 is located within the concave portion 114.

[0056] Then, push the drawer 300 backward to its extreme position, that is, from the state of Figures 2 to 4 to reach the state of Figure 5 and Figure 6 The mounting post 410 moves upward along the slope 1121, and the mounting post 420 moves upward along the slope 1141. Since the slope of the slope 1141 is greater than that of the two slopes 1121 and 1141, the rear end of the upper cover 400 is tilted upward.

[0057] Finally, the user releases the drawer 300, and the drawer 300 bounces forward a preset distance and then locks to the box body 10. During this process, under the action of the gravity of the upper cover 400, the mounting post 410 slides forward and downward along the slope 1121, and the mounting post 420 slides forward and downward along the slope 1141, and finally reaches the state where the drawer 300 shown in Figure 7 and Figure 8 is closed.

[0058] In some embodiments, as shown in Figure 2 , Figure 3 Figure 4 and Figure 9 above, a top plate 120 extending parallel to the slide rail 110 is further provided above each slide rail 110, and each mounting post 410, 420 is located between the slide rail 110 and the top plate 120. The slide rail 110 and the top plate 120 form a chute structure to better restrain the mounting posts 410, 420. When the track plates 100, 200 are provided, the top plate 120 can also extend from the inner surface of the track plates 100, 200.

[0059] The top plate 120 may be provided with gaps 121, 123 corresponding to the concave portions 112, 114 respectively, so that when the upper cover 400 is taken out upward, the gaps 121, 123 respectively give way to the mounting posts 410, 420. At the same time, it is also convenient to install the upper cover 400 from top to bottom. An opening 125 formed between the front end of the top plate 120 and the side plate enables the user to draw out the upper cover 400 from the front side of the slide rail 110.

[0060] In some embodiments, as shown in Figures 10 to 12As shown, the refrigerator further includes a sealing strip 500 extending along the transverse direction of the upper cover 400. The sealing strip 500 generally may include a mounting portion 510 and a sealing portion 530. Among them, the mounting portion 510 is used for fixing with the front end of the upper cover 400. The sealing portion 530 extends forward from the front end of the mounting portion 510, and while extending forward, the sealing portion 530 gradually bends downward, which is a one-way bend. When the drawer 300 moves backward, the sealing portion 530 is pushed backward by the front end plate of the drawer 300 and elastically deformed, so as to seal the gap between the front end of the upper cover 400 and the front end plate of the drawer 300, achieving the effect of sealing and heat insulation. In order to deform better, the sealing portion 530 can be made of a sealing material with greater elasticity.

[0061] Through multiple experimental verifications by R & D personnel, it is confirmed that this bending structure of the sealing portion 530 is more prone to elastic deformation, resulting in less resistance from the sealing strip 500 when the drawer 300 is pushed backward, making it more labor-saving for the user to press the drawer 300, and the experience is very good.

[0062] Of course, in some embodiments not shown in the drawings, the sealing portion 530 can also extend forward from the front end of the mounting portion 510 and gradually bend upward at the same time. This structure will not be elaborated herein.

[0063] As Figure 12 shown, the curvature of the sealing portion 530 can be gradually increased from the back to the front, which can be more conducive to the force-bearing deformation of the sealing portion 530 and make it more labor-saving to push the drawer 300 backward.

[0064] In some embodiments, the sealing strip 500 further includes a support portion 520. The support portion 520 is made of a hard material (such as hard plastic). The support portion 520 extends forward from the front end of the mounting portion 510, is located on the concave side of the sealing portion 530 and is spaced from the sealing portion 530. When the sealing portion 530 is pushed backward and its front end contacts the support portion 520, the support portion 520 supports the sealing portion 530 and forms a heat insulation cavity with the sealing portion 530.

[0065] After the sealing portion 530 is elastically deformed by the backward push of the drawer 300 to a certain extent, it is supported by the support portion 520, which can prevent the excessive elastic deformation of the sealing portion 530 from affecting its service life. Moreover, the heat insulation cavity formed between the sealing portion 530 and the support portion 520 can enhance the heat insulation performance at the sealing strip 500.

[0066] In some embodiments, as Figure 12As shown, the front end of the upper cover 400 has a front-side open slot 450. In the middle of the slot 450, there is an insertion plate 453 that divides the internal space of the slot 450 vertically. The rear end of the installation part 510 has a rear-side open groove 511. The installation part 510 is inserted into the slot 450, and the insertion plate 453 is inserted into the groove 511, so that the installation part 510 is fixed to the upper cover 400. The sealing strip 500 is fixed to the upper cover 400 by the above-mentioned plug-in method, and both installation and disassembly are very convenient.

[0067] Furthermore, elastic locking teeth 5112 that gradually slope forward can be extended from the top wall and the bottom wall of the groove 511 respectively. After the installation part 510 is inserted into the slot 450, the elastic locking teeth 5112 are elastically deformed by the extrusion of the insertion plate 453 and cling to the insertion plate 453 by virtue of the elastic force, so that the position of the installation part 510 can be more stable.

[0068] In some embodiments, as Figure 13 and Figure 14 shown, the drawer 300 includes a drawer body 310, a front frame 330, and a glass panel 320. The front frame 330 and the glass panel 320 form the front panel of the drawer.

[0069] The drawer body 310 is used for storing items. The drawer body 310 can be as Figure 13 shown, including a bottom plate 311, two side plates 312, and a back plate 313. Among them, the bottom plate 311 is used for carrying items. The two side plates 312 extend upward from the transverse two ends of the bottom plate 311 respectively. The back plate 313 extends upward from the rear end of the bottom plate 311. The front frame 330 is fixedly connected to the two side plates 312. For example, through screw holes 302 and 305, the front frame 330 and the side plates 312 can be connected by screws.

[0070] The front frame 330 is vertically installed on the front side of the drawer body 310 and is made of a metal material, such as aluminum alloy. The glass panel 320 is fixedly installed on the front frame 330 so that the front frame 330 surrounds the glass panel 320.

[0071] As Figure 14 shown, to facilitate the installation of the glass panel 320, the front frame 330 has a clamping groove 301 for clamping and fixing the edge of the glass panel 320.

[0072] Since the stiffness of the metal frame and the glass panel is relatively large, when the user pushes the drawer 300, the deformation of the drawer 300 is very small, and there will be no influence on the mutual sliding between the drawer 300 slide rail 110 and the cabinet 10 slide rail 110 due to deformation, making the forward and backward sliding of the drawer 300 very smooth and the user very labor-saving.

[0073] As Figure 13 and Figure 14As shown, the front frame 330 and the glass panel 320 are both square. For ease of manufacture, the front frame 330 can be assembled from two parts, that is, the front frame 330 includes a "U" - shaped frame 332 and a bottom edge 334 which are detachably connected. The "U" - shaped frame 332 includes a top edge 3321 and two side edges 3322 that extend downward from both ends of the top edge 3321 respectively. Both ends of the bottom edge 334 are respectively connected to the bottom ends of the two side edges 3322.

[0074] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the disclosed content of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all such other variations or modifications.
