Description

Technical Field

[0001] The invention relates to a refrigeration and freezing device, in particular to a refrigerator. Background Art

[0002] The push-to-open drawer structure is widely used in cabinet drawers or furniture drawers. Its structure is similar to the top pressing structure of a ballpoint pen. Press once to extend the pen tip, and press again to retract the pen tip.

[0003] Some refrigerators may also use a push-open drawer. A push-open component is provided between the drawer and the housing. When the drawer is closed, the push-open component locks the drawer to the housing.

[0004] When the user wants to open the drawer, he pushes the front panel of the drawer backwards, so that the drawer moves backwards a short distance (such as 5mm), and at the same time, the push-open component unlocks the drawer. The user then stops pushing the drawer backwards, and the push-open component uses elastic force to bounce the drawer forward a certain distance. Then the user can manually pull the drawer forward to open it.

[0005] When closing the drawer, the user pushes the drawer backwards, so that it overcomes the elastic force of the push-open component and moves to the rear limit position. The user then lets go, and the drawer rebounds forward a short distance under the elastic force of the push-open component, completing the locking of the drawer.

[0006] The particularity of refrigerator drawers is that there is an upper cover on top of them. 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 drawer movement process, especially at the beginning of opening or the end of closing, interference, friction, and collision with the upper cover often cause many problems such as poor sealing between the drawer and the upper cover, obstruction of user pushing, and noise, which seriously affect the user experience. In addition, the drawer is relatively heavy after storing things, and it often deforms when being pushed, which affects the normal coordination between the drawer slide rail and the box slide rail, making the sliding between the drawer and the box body not smooth, which makes the user feel laborious. The above points have become important obstacles to the large-scale implementation of push-pop drawers in refrigerators. Summary of the invention

[0007] An object of the present invention is to provide a refrigerator, which can reduce the deformation of the drawer caused by pushing when the user manually pushes the drawer to open and close, so that the drawer can move more smoothly.

[0008] Another object of the present invention is to reduce the noise generated by the push-open drawer colliding with the upper cover during the closing and rebounding process, and to enhance the sealing performance between the drawer and the upper cover.

[0009] In particular, the present invention provides a refrigerator, comprising a cabinet and a push-and-pop drawer that can be pushed and pulled forward and backward and is opened and closed inside the cabinet. When the drawer is closed, it is first pushed backward to a rear limit position, and then rebounds forward a preset distance under elastic force and is locked to the cabinet. The drawer comprises: a drawer body for storing things; a front frame that is vertically installed on the front side of the drawer body and is made of metal material; and a glass panel that is fixedly installed on the front frame so that the front frame surrounds the glass panel.

[0010] Optionally, a clamping groove is provided on the front frame for clamping and fixing the edge of the glass panel.

[0011] Optionally, the front frame and the glass panel are both square.

[0012] Optionally, the front frame includes a detachably connected "U"-shaped frame and a bottom edge; and the "U"-shaped frame includes a top edge and two side edges extending downward from both ends of the top edge, and the two ends of the bottom edge are respectively connected to the bottom ends of the two side edges.

[0013] Optionally, the front frame is made of aluminum alloy.

[0014] Optionally, the drawer body includes: a bottom plate for carrying items; two side plates extending upward from the lateral ends of the bottom plate respectively; and a back plate extending upward from the rear end of the bottom plate; and the front frame is fixedly connected to the two side plates.

[0015] Optionally, the refrigerator also includes: two slide rails, which are respectively arranged on the two lateral walls inside the box body and extend forward and backward, each slide rail forming at least one slope gradually ascending from front to back; and an upper cover, with the lateral ends respectively placed on the two slide rails to cover the upper opening of the drawer; when the drawer is pushed backward to the rear limit position, the upper cover moves backward and up along the slope; after the drawer rebounds forward and is locked, the upper cover moves forward and downward along the slope due to its own gravity to fit tightly against the drawer.

[0016] Optionally, a buffer stop block is also installed on each slide rail; and when the upper cover moves along the slope to a position close to the drawer, it stops moving due to the buffering block.

[0017] Optionally, each slide rail has at least one downwardly recessed inner recess, and the rear surface of the inner recess constitutes a slope; and each lateral end of the upper cover has at least one laterally extending mounting column, and each mounting column is located in an inner recess.

[0018] Optionally, each slide rail has two inner recesses arranged front to back; and each end of the upper cover has two mounting posts arranged front to back.

[0019] In the refrigerator of the present invention, the front end of the drawer is provided with a metal frame and a glass panel, which makes it more rigid. When the user pushes the drawer, the deformation of the drawer is very small, and the sliding between the drawer slide rail and the box slide rail will not be affected by deformation, so that the drawer can slide back and forth very smoothly, which saves the user a lot of effort.

[0020] Furthermore, the refrigerator of the present invention is provided with a push-to-open drawer, and the upper cover of the drawer is arranged 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 is locked to the box body by the elastic force, the upper cover moves forward and downward along the slope under the action of its own gravity, so as to be closely 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, so that the drawer can be better sealed. 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 backward movement of the drawer, making the user more labor-saving. The present invention has a simple structure, but is very practical in function. In addition, the number of parts is small, the possibility of failure is small, and the reliability is very high.

[0021] Furthermore, the refrigerator of the present invention is also provided with a buffer stop block. When the drawer is closed, when the upper cover moves along the slope to a position close to the drawer, it will be blocked by the buffer stop block and stop moving. The buffer stop block can buffer the impact force of the upper cover moving and reduce the impact noise.

[0022] 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, so that the rear end of the upper cover can be tilted upward when it moves backward, which can facilitate the subsequent movement forward and downward along the slope more smoothly, make it more closely attached to the drawer, and improve the sealing performance.

[0039] Refer to the following Figures 1 to 14The refrigerator of the embodiment of the present invention is described in the following. The directions or positional relationships indicated by "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. are directions or positional relationships based on the directions or positional relationships indicated in the accompanying drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention.

[0040] The embodiment of the present invention provides a refrigerator. The refrigerator of the embodiment of the present invention can use a vapor compression refrigeration cycle system for refrigeration to provide cold capacity. The vapor compression refrigeration cycle system includes a compressor, a condenser, an evaporator, a throttling device and other refrigeration accessories.

[0041] In some embodiments, Figure 1 As shown, the refrigerator includes a box body 10 and a push-pull type open and close drawer 300 which can be pushed and pulled forward and backward and is arranged inside the box body 10. A push-pull component is arranged between the drawer 300 and the box body 10. When the drawer 300 is in a closed state, the push-pull component locks the drawer 300 to the box body 10. When the user wants to open the drawer 300, he presses the front end plate of the drawer 300 backward to make the drawer 300 move backward a preset distance (such as 5mm) to overcome the elastic force of the push-pull component, and 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 will use the elastic force to rebound the drawer 300 forward a distance (such as 10cm), and then the user manually pulls the drawer 300 forward. When the user wants to close the drawer 300, he first pushes the drawer 300 backward so that it overcomes the elastic force of the push-open component and moves to a rear limit position (at the rear limit position, the drawer 300 cannot move further backward). The user then lets go, and the drawer 300 rebounds forward a preset distance (e.g., 5 mm) under the elastic force of the push-open component, thereby completing the locking of the drawer 300.

[0042] The drawer 300 of push-open type opening and closing is widely used in cabinet drawers and furniture drawers in the prior art. Therefore, the specific structure of the push-open structure is not described in detail here.

[0043] 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. Figure 2 As shown, the refrigerator may further include two slide rails 110 and an upper cover 400. The two slide rails 110 are respectively arranged on the two side walls of the interior of the box body 10 in the horizontal direction (i.e., the left and right directions marked in the figure) and extend forward and backward, and each slide rail 110 is formed with at least one slope 1121, 1141 that gradually rises from front to back. The lateral ends of the upper cover 400 are respectively placed on the two slide rails 110 to cover the upper opening of the drawer 300.

[0044] For example Figure 2Two track plates 100 and 200 may be provided. The two track plates 100 and 200 are respectively installed on the two lateral side walls inside the box body 10. Each slide rail 110 is formed on the inner surface of a track plate 100 and 200. The drawer 300 may also be installed on the two track plates 100 and 200 in a manner of being pushed and pulled forward and backward. Figure 3 and Fig. 9 The two lateral side walls of the drawer 300 respectively have first slide rails 390 extending forward and backward, and the two track plates 100 and 200 respectively have second slide rails 190 extending forward and backward. Each second slide rail 190 cooperates with a first slide rail 390 to allow the drawer 300 to be pushed and pulled forward and backward.

[0045] When the drawer 300 is pushed backward to the rear limit position, the upper cover 400 moves backward and upward along the slopes 1121 and 1141. After the drawer 300 rebounds forward and is locked 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 abut against the drawer 300. In addition, after the drawer 300 is closed, due to the action of the slopes 1121 and 1141, the upper cover 400 still has a tendency to slide forward and downward, thereby better sealing the drawer 300.

[0046] The drawer described in the embodiment of the present invention is particularly suitable for use as a drawer for partitioning between dry and wet areas. The drawers used in the dry area or the wet area have higher requirements for sealing.

[0047] Since the upper cover 400 is "movable", when the drawer 300 is closed, the upper cover 400 moves back a distance with the drawer 300, which can avoid the upper cover 400 from generating additional resistance to the drawer's backward movement, making the user more labor-saving. The present invention has a simple structure but very practical functions. In addition, the number of parts is small, the possibility of failure is small, and the reliability is very high.

[0048] In some embodiments, a buffer stopper 130 is also installed on each slide rail 110. When the upper cover 400 moves forward and downward along the slopes 1121 and 1141 to a position close to the drawer 300, it stops moving due to the buffering and blocking of the buffer stopper 130. The buffer stopper 130 can buffer the impact force of the movement of the upper cover 400 and reduce the impact noise. The buffer stopper 130 can be made of a material with high elasticity such as rubber.

[0049] Figures 2 to 4 The figure shows an optional structure of the slide rail 110. The figure only shows the structure of the slide rail 110 on the left side. The slide rail on the right side is symmetrically arranged with the slide rail 110 on the left side.

[0050] like Figures 2 to 4As shown, each slide rail 110 has at least one downwardly recessed inner recess 112, 114, and the rear surface of the inner recess 112, 114 forms a slope 1121, 1141. Each lateral end of the upper cover 400 has at least one transversely extending mounting post 410, 420, and the number of mounting posts 410, 420 is the same as the number of the inner recess 112, 114, and each mounting post 410, 420 is located in one inner recess 112, 114. In addition to forming the slope 1121, 1141 on the rear surface of the inner recess 112, 114, another function is to constrain the position of the mounting posts 410, 420. Unless the mounting posts 410, 420 are subjected to a force large enough to cross the inner recess 112, 114, the mounting posts 410, 420 will not move forward easily. That is, when the drawer 300 moves forward, even if the upper cover 400 is subjected to the friction force of the top of the drawer 300 moving forward, it will not move forward with the drawer 300 easily, which makes the position of the upper cover 400 more stable.

[0051] The surfaces of the inner recesses 112 and 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 connected to the slide rail 110 only through the mounting posts 410 and 420, so that the contact area between the upper cover 400 and the slide rail 110 is very small, which is convenient for matching with the slopes 1121 and 1141.

[0052] like Figures 2 to 4 As shown, each slide rail 110 can have two inner recesses 112 and 114 arranged front and back, and each end of the upper cover 400 can have two mounting posts 410 and 420 arranged front and back. The front and rear ends of the upper cover 400 are supported respectively, the force is more uniform, and the position is more stable.

[0053] Furthermore, if Figures 2 to 4 As shown, the slope of the two slopes 1121 and 1141 of each slide rail 110 can be made greater than the slope of the slope 1121 at the front side. For example, when the inner recesses 112 and 114 are arc-shaped, the radius of the inner recess 114 at the rear side is made smaller than the radius of the inner recess 112 at the front side. In this way, the rear slope 1141 is steeper, and the rear end of the upper cover 400 is tilted upward when the upper cover 400 moves backward, which can facilitate the subsequent smoother movement of the upper cover 400 forward and downward along the slopes 1121 and 1141, so that the upper cover 400 is more closely attached to the drawer 300, and the sealing performance is better.

[0054] like Figure 3 As shown, the buffer stopper 130 of each slide rail 110 can be disposed in the inner recess 112 at the front side to block the mounting column 410 at the front of the upper cover 400. Since the upper cover 400 is light in weight, only one buffer stopper 130 is provided to buffer the upper cover 400, and the structure is simpler.

[0055] Below through Figures 2 to 8 The closing process of the drawer 300 in the embodiment of the present invention is introduced.

[0056] Figures 2 to 4 The drawing 300 is in an open state. At this time, the mounting post 410 is located in the inner recess 112 and is blocked from moving forward by the buffer stop block 130. The mounting post 420 is located in the inner recess 114.

[0057] Then, push the drawer 300 degrees to the limit position, that is, Figures 2 to 4 The status reached Figure 5 and Figure 6 The mounting post 410 moves up along the slope 1121, and the mounting post 420 moves up along the slope 1141. Since the slope 1141 has a greater slope than the slopes 1121 and 1141, the rear end of the upper cover 400 is tilted upward.

[0058] Finally, the user releases the drawer 300, and the drawer 300 rebounds forward to a preset distance and then locks to the box body 10. In this process, under 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 Figure 7 and Figure 8 The drawer 300 is shown in a completely closed state.

[0059] In some embodiments, Figure 2 , Figure 3 Figure 4 as well as Fig. 9 As shown, each slide rail 110 is provided with a top plate 120 extending parallel to the 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 slide groove structure to better constrain the mounting posts 410, 420. When the track plates 100, 200 are provided, the top plate 120 can also extend from the inner side surface of the track plates 100, 200.

[0060] The top plate 120 may be provided with notches 121 and 123 corresponding to the inner recesses 112 and 114, so that when the upper cover 400 is taken out upward, the notches 121 and 123 respectively make way for the mounting posts 410 and 420. At the same time, it is also convenient to mount the upper cover 400 from top to bottom. The opening 125 formed between the top plate 120 and the front end of the side plate allows the user to pull out the upper cover 400 from the front side of the slide rail 110.

[0061] In some embodiments, Figures 10 to 12As shown, the refrigerator also includes a sealing strip 500 extending in the transverse direction of the upper cover 400. The sealing strip 500 generally includes a mounting portion 510 and a sealing portion 530. Among them, the mounting portion 510 is used to be fixed to the front end of the upper cover 400. The sealing portion 530 extends forward from the front end of the mounting portion 510, and the sealing portion 530 gradually bends downward while extending forward, which is a one-way bend. When the drawer 300 moves backward, the sealing portion 530 is pushed back by the front end plate of the drawer 300 and elastically deforms, thereby sealing the gap between the front end of the upper cover 400 and the front end plate of the drawer 300, and 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.

[0062] The R&D personnel have verified through many experiments that this curved structure of the sealing part 530 is easier to deform elastically, so that the drawer 300 encounters less resistance from the sealing strip 500 when pushed back, and the user can press the drawer 300 more effortlessly, providing a very good experience.

[0063] Of course, in some embodiments not shown in the drawings, the sealing portion 530 may also extend forward from the front end of the mounting portion 510 and gradually bend upward at the same time, and this structure will not be described in detail herein.

[0064] like Fig.12 As 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 stress deformation of the sealing portion 530 and make it more labor-saving to push the drawer 300 backward.

[0065] In some embodiments, the sealing strip 500 further includes a support portion 520. The support portion 520 is made of a hard material (e.g., 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 apart from the sealing portion 530. When the sealing portion 530 is pushed back so that its front end contacts the support portion 520, the support portion 520 supports the sealing portion 530 and forms a heat-insulating cavity with the sealing portion 530.

[0066] After the sealing part 530 is pushed back by the drawer 300 and elastically deformed to a certain extent, it is supported by the support part 520, which can prevent the sealing part 530 from elastically deforming too much and affecting its service life. In addition, the heat-insulating cavity formed between the sealing part 530 and the support part 520 can enhance the heat-insulating performance of the sealing strip 500.

[0067] In some embodiments, Fig.12As shown, the front end of the upper cover 400 has a slot 450 with an open front side. The middle of the slot 450 has an insert plate 453 that divides the internal space of the slot 450 up and down. The rear end of the mounting portion 510 has a groove 511 that is open to the rear. The mounting portion 510 is inserted into the slot 450, and the insert plate 453 is inserted into the groove 511, so that the mounting portion 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 removal are very convenient.

[0068] Furthermore, the top wall and the bottom wall of the groove 511 can extend respectively with elastic teeth 5112 which are gradually inclined forward. After the mounting portion 510 is inserted into the slot 450, the elastic teeth 5112 are elastically deformed by the compression of the plug plate 453 and are tightly attached to the plug plate 453 by elastic force, so that the position of the mounting portion 510 can be more stable.

[0069] In some embodiments, Fig.13 and Fig.14 As 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 constitute a front panel of the drawer.

[0070] The drawer body 310 is used for storing items. Fig.13 As shown, the front frame 330 includes a bottom plate 311, two side plates 312 and a back plate 313. The bottom plate 311 is used to carry articles. The two side plates 312 extend upward from the lateral 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, the front frame 330 and the side plates 312 can be connected by screws through the screw holes 302 and the screw holes 305.

[0071] The front frame 330 is vertically mounted 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 mounted on the front frame 330 so that the front frame 330 surrounds the glass panel 320 .

[0072] like Fig.14 As shown, in order to install the glass panel 320 , a clamping groove 301 is provided on the front frame 330 for clamping and fixing the edge of the glass panel 320 .

[0073] Due to the greater rigidity of the metal frame and the glass panel, when the user pushes the drawer 300, the deformation of the drawer 300 is very small, and the sliding rails 110 of the drawer 300 and the sliding rails 110 of the box 10 will not be affected by deformation, making the drawer 300 slide back and forth very smoothly, and the user saves a lot of effort.

[0074] like Fig.13 and Fig.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 detachably connected "U"-shaped frame 332 and a bottom edge 334. The "U"-shaped frame 332 includes a top edge 3321 and two side edges 3322 extending downward from both ends of the top edge 3321. The two ends of the bottom edge 334 are respectively connected to the bottom ends of the two side edges 3322.

[0075] 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 based on the content disclosed in 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 recognized as covering all these other variations or modifications.
