The user releases his hand immediately, and the drawer rebounds forwards for a short distance under the action of the elastic force of the pushing and ejecting part to complete the locking of the drawer.

The particularity of the refrigerator drawer is that an upper cover is arranged above the refrigerator drawer. When the drawer is closed, the upper cover tightly seals the upper side opening of the drawer. When the drawer is pulled forward to be opened, the upper cover does not move forward along with the drawer. The moving process of the drawer, especially the initial opening stage or the final closing stage, often causes problems of poor sealing between the drawer and the upper cover, blocked pushing of a user, noise and the like due to interference, friction and collision between the drawer and the upper cover, and the user experience is seriously influenced. This also becomes a significant obstacle to the difficulty of implementing push-pull drawers on a large scale on a refrigerator.

A refrigerator according to an embodiment of the present invention is described below with reference to fig. 1 to 14. In the drawings, the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", and the like denote orientations and positional relationships indicated by the drawings. As such, the description is for convenience and simplicity of description only and is not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

The embodiment of the utility model provides a refrigerator. The utility model discloses refrigerator can adopt vapor compression refrigeration cycle system to refrigerate to provide cold volume. The vapor compression refrigeration cycle system includes a compressor, a condenser, an evaporator, a throttling device, and other refrigeration accessories.

In some embodiments, as shown in fig. 1, the refrigerator includes a cabinet 10 and a drawer 300 that is opened and closed in a push-and-pull type and is disposed inside the cabinet 10. An elastic pushing part is provided between the drawer 300 and the cabinet 10. When the drawer 300 is in the closed state, the urging member locks the drawer 300 to the cabinet 10. When the user wants to open the drawer 300, the user pushes the front panel of the drawer 300 backward, so that the drawer 300 moves backward by a predetermined distance (e.g., 5mm) against the elastic force of the eject member, and at the same time, the eject member unlocks the drawer 300. The user then stops pushing the drawer 300 backward, the spring member will spring the drawer 300 forward by a certain distance (e.g. 10cm), and then the user manually pulls the drawer 300 forward. When a user wants to close the drawer 300, the user pushes the drawer 300 backwards to move to a rear limit position (at the rear limit position, the drawer 300 cannot move backwards continuously) against the elastic force of the elastic pushing component, the user releases his hand immediately, and the drawer 300 rebounds forwards for a preset distance (for example, 5mm) under the elastic force of the elastic pushing component, so as to complete the locking of the drawer 300.

The drawer 300 opened and closed by pushing and ejecting is widely used in a cabinet drawer and a furniture drawer in the related art. Therefore, the detailed structure of the push spring structure is not described herein.

Besides the drawer 300, the refrigerator may further include other drawers and door bodies, such as the drawer 40 and the door body 20, which are not described in detail. As shown in fig. 2, the refrigerator may further include two slide rails 110 and an upper cover 400. The two slide rails 110 are respectively disposed on two lateral walls in the interior of the box 10 (i.e., in the left-right direction indicated in the figure) and extend forward and backward, and each slide rail 110 is formed with at least one slope 1121, 1141 that gradually slopes upward from front to back. The upper cover 400 is disposed at both lateral ends thereof on the two slide rails 110, respectively, to cover the upper opening of the drawer 300.

For example, fig. 2 may provide two track plates 100, 200. The two track plates 100 and 200 are respectively installed on two lateral walls inside the box body 10. Each of the slide rails 110 is formed on an inner side surface of one of the rail plates 100, 200. The drawer 300 can be installed on the two rail plates 100 and 200 to be pushed and pulled back and forth. Referring to fig. 3 and 9, two lateral side walls of the drawer 300 are respectively provided with a first slide rail 390 extending forward and backward, two rail plates 100 and 200 are respectively provided with a second slide rail 190 extending forward and backward, and each second slide rail 190 is matched with one first slide rail 390 to allow the drawer 300 to be pushed and pulled forward and backward.

During the process that the drawer 300 is pushed backward to the rear limit position, the upper lid 400 moves backward and moves upward along the slopes 1121, 1141. After the drawer 300 is rebounded forward and locked to the cabinet 10, the upper cover 400 moves forward and downward along the slopes 1121, 1141 by its own weight to be tightly abutted against the drawer 300. In addition, after the drawer 300 is completely closed, the upper cover 400 still has a tendency to slide forward and downward due to the slopes 1121, 1141, so that the drawer 300 can be better sealed.

The embodiment of the utility model provides a drawer specially adapted do wet subregion's drawer, dry district or wet district adopted drawer to the leakproofness requirement higher.

Because the upper cover 400 is movable, when the drawer 300 is closed, the upper cover 400 moves backwards for a certain distance along with the drawer 300, so that the phenomenon that the upper cover 400 generates extra resistance to the backward movement of the drawer can be avoided, and a user can save more labor. The utility model discloses simple structure, but the function is very practical. And the number of parts is less, the possibility of failure is low, and the reliability is high.

In some embodiments, a buffer stop 130 is further mounted on each slide rail 110. When the upper cover 400 moves forward and downward along the slopes 1121, 1141 to a position abutting against the drawer 300, the movement is stopped by the buffer stop 130. The buffering stopper 130 can buffer the impact force of the movement of the upper cover 400, and reduce the impact noise. The buffering stopper 130 may be made of a material having a large elasticity, such as rubber.

An alternative configuration of the slide rail 110 is illustrated in fig. 2-4. Only the structure of the slide rail 110 on the left side is illustrated in the drawing. The slide rail located on the right side is arranged symmetrically to the slide rail 110 located on the left side.

As shown in fig. 2 to 4, each slide rail 110 has at least one concave portion 112, 114 depressed downward, and rear surfaces of the concave portions 112, 114 form sloping surfaces 1121, 1141. Each lateral end of the upper cover 400 has at least one mounting post 410, 420 extending laterally, respectively, the number of mounting posts 410, 420 being the same as the number of the internal recesses 112, 114, each mounting post 410, 420 being located within one of the internal recesses 112, 114. In addition to forming the rear surfaces of the inner recesses 112, 114 with the ramped surfaces 1121, 1141, another function of the inner recesses 112, 114 is to constrain the position of the mounting posts 410, 420 so that the mounting posts 410, 420 do not easily advance unless the mounting posts 410, 420 are subjected to a sufficient force to clear the inner recesses 112, 114. That is, when the drawer 300 is moved forward, even if the upper cover 400 is subjected to a frictional force of the drawer 300 at the top thereof, it does not easily move forward along with the drawer 300, which makes the position of the upper cover 400 stable.

The surfaces of the concave portions 112, 114 are rounded to facilitate design and machining. Of course, other curved surfaces may be used. The two ends of the upper cover 400 are connected to the sliding rail 110 only through the mounting posts 410 and 420, so that the contact area between the upper cover and the sliding rail 110 is small, and the upper cover is convenient to be matched with the slopes 1121 and 1141.

As shown in fig. 2 to 4, each slide rail 110 may have two inner recesses 112, 114 arranged in tandem, and each end of the upper cover 400 may have two mounting posts 410, 420 arranged in tandem. The front end and the rear end of the upper cover 400 are respectively supported, so that the stress is more uniform, and the position is more stable.

Further, as shown in fig. 2 to 4, of the two slope surfaces 1121, 1141 of each slide rail 110, the slope surface 1141 located at the rear side has a slope larger than that of the slope surface 1121 located at the front side, for example, when the inner concave portions 112, 114 are arc-shaped, the radius of the inner concave portion 114 at the rear side is smaller than that of the inner concave portion 112 at the front side. Therefore, the slope 1141 of the rear surface is steeper, and the rear end of the upper cover 400 is tilted upward when the upper cover is moved backward, which facilitates the subsequent movement of the upper cover along the slopes 1121, 1141 more smoothly and forward and downward, so that the upper cover is more tightly attached to the drawer 300, and the sealing performance is better.

As shown in fig. 3, the buffering stopper 130 of each slide rail 110 may be disposed in the inner recess 112 at the front side for blocking the mounting post 410 at the front of the upper cover 400. Since the upper cover 400 is light in weight, the buffering of the upper cover 400 can be completed only by arranging one buffering stopper 130, and the structure is simpler.

The closing process of the drawer 300 according to the embodiment of the present invention is described below with reference to fig. 2 to 8.

Fig. 2 to 4 illustrate an opened state of the drawer 300. At this point, the mounting post 410 is positioned within the interior recess 112 and is blocked from the forward path by the bumper stop 130. The mounting post 420 is located within the interior recess 114.

Then, the rear limit position of the drawer 300 is pushed rearward, i.e., the state of fig. 5 and 6 is reached from the state of fig. 2 to 4. The mounting post 410 moves up along the sloping surface 1121 and the mounting post 420 moves up along the sloping surface 1141. The slope surface 1141 has a larger slope among the two slope surfaces 1121, 1141, so that the rear end of the upper cover 400 is tilted upward.

Finally, the user releases the drawer 300, and the drawer 300 is bounced forward by a predetermined distance and then locked to the cabinet 10. In the 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, so as to finally achieve the state of the drawer 300 shown in fig. 7 and 8 being completely closed.

In some embodiments, as shown in fig. 2, 3, 4 and 9, each of the sliding rails 110 further has a top plate 120 extending parallel to the sliding rail 110 above the sliding rail 110, and each of the mounting posts 410, 420 is located between the sliding rail 110 and the top plate 120. The sliding rail 110 and the top plate 120 form a sliding slot structure to better constrain the mounting posts 410, 420. When the track plates 100 and 200 are provided, the top plate 120 may be extended from the inner surfaces of the track plates 100 and 200.

The top plate 120 may have notches 121 and 123 corresponding to the inner recesses 112 and 114, respectively, so that when the top cover 400 is taken out upward, the notches 121 and 123 may give way for the mounting posts 410 and 420, respectively. At the same time, it is also convenient to install the upper cover 400 from top to bottom. An opening 125 is formed between the top plate 120 and the front ends of the side plates so that the user can draw the upper cover 400 from the front side of the slide rail 110.

In some embodiments, as shown in fig. 10 to 12, the refrigerator further includes a sealing strip 500 extending in a transverse direction of the upper cover 400. The sealing strip 500 may generally include a mounting portion 510 and a sealing portion 530. The mounting portion 510 is fixed to the front end of the upper cover 400. The sealing part 530 extends forward from the front end of the mounting part 510, and the sealing part 530 is gradually bent downward as it extends forward, being a unidirectional bend. When the drawer 300 moves backward, the sealing part 530 is pushed backward by the front end plate of the drawer 300 and is elastically deformed, thereby sealing a gap between the front end of the upper cover 400 and the front end plate of the drawer 300, and achieving an effect of sealing and insulating heat. For better deformation, the sealing part 530 may be made of a sealing material having a greater elasticity.

The research and development personnel verify through experiments for a plurality of times that the bending structure of the sealing part 530 is easier to elastically deform, so that the resistance of the sealing strip 500 when the drawer 300 is pushed backwards is smaller, the user can press the drawer 300 more laborsavingly, and the experience is very good.

Of course, in some embodiments not illustrated in the drawings, the sealing portion 530 may extend forward from the front end of the mounting portion 510 and gradually curve upward, and the description of such a structure will not be repeated.

As shown in fig. 12, the curvature of the sealing portion 530 may be gradually increased from the rear to the front, which may further facilitate the forced deformation of the sealing portion 530, and further save the effort of pushing the drawer 300 backwards.

In some embodiments, seal strip 500 further includes a support portion 520. The support 520 is made of a hard material (e.g., hard plastic). The supporting portion 520 extends forward from the front end of the mounting portion 510, is positioned at a concave side of the sealing portion 530, and is spaced apart from the sealing portion 530. When the sealing part 530 is pushed backward so that the front end thereof contacts the supporting part 520, the supporting part 520 supports the sealing part 530 and forms an insulating cavity together with the sealing part 530.

The sealing part 530 is supported by the supporting part 520 after being elastically deformed to a certain extent by the rear pushing of the drawer 300, so that the influence of the excessive elastic deformation of the sealing part 530 on the service life thereof can be avoided. Also, an insulation cavity is further formed between the sealing portion 530 and the supporting portion 520 to enhance the insulation performance at the weather strip 500.

In some embodiments, as shown in fig. 12, the front end of the upper cover 400 has a slot 450 with an open front side. The middle portion of the insertion groove 450 has an insertion plate 453 that partitions the inner space of the insertion groove 450 up and down. The rear end of the mounting part 510 has a recess 511 opened rearward, the mounting part 510 is inserted into the insertion groove 450, and the insert plate 453 is inserted into the recess 511, so that the mounting part 510 is fixed to the upper cover 400. The sealing strip 500 is fixed on the upper cover 400 in the above-mentioned inserting manner, and the installation and the detachment are very convenient.

Further, the top and bottom walls of the groove 511 may be extended with elastic latches 5112 inclined gradually forward, respectively. After the mounting part 510 is inserted into the insertion groove 450, the elastic latch 5112 is elastically deformed by the pressing force of the insertion plate 453 and is closely attached to the insertion plate 453 by the elastic force, so that the position of the mounting part 510 can be more stable.

In some embodiments, as shown in fig. 13 and 14, the drawer 300 includes a drawer body 310, a front frame 330, and a glass panel 320. The front bezel 330 and the glass panel 320 constitute a front panel of the drawer.

The drawer body 310 serves to store articles. The drawer body 310 may include a bottom plate 311, two side plates 312, and a back plate 313, as shown in fig. 13. Wherein the bottom panel 311 is used for carrying an article. The two side plates 312 extend upward from both lateral ends of the bottom plate 311, respectively. A 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, front bezel 330 and side plate 312 may be connected by screws through screw holes 302 and 305.

The front bezel 330 is mounted upright 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 to the front bezel 330 such that the front bezel 330 surrounds the glass panel 320.

As shown in FIG. 14, in order to mount the glass panel 320, the front frame 330 has a clamping groove 301 for clamping and fixing the edge of the glass panel 320.

Because the rigidity of the metal frame and the glass panel is higher, when a user pushes the drawer 300, the deformation of the drawer 300 is very small, and the sliding between the sliding rail 110 of the drawer 300 and the sliding rail 110 of the box body 10 cannot be influenced by the deformation, so that the drawer 300 slides forwards and backwards very smoothly, and the user saves labor.

As shown in fig. 13 and 14, the front bezel 330 and the glass panel 320 are both square. For ease of manufacture, the front frame 330 may be assembled from two parts, i.e., the front frame 330 includes a removably attached "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 downwardly from each end of the top edge 3321. The bottom edge 334 is connected at its ends to the bottom ends of the two side edges 3322.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
