Description

refrigerator

technical field

The utility model relates to a refrigerating and freezing device, in particular to a refrigerator.

Background technique

The push-pull open and close 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 the tip to extend, and press it again to retract the tip.

Some refrigerators also have push-pull drawers. A pusher part is arranged between the drawer and the box body. When the drawer is closed, the pusher part locks the drawer to the box.

When the user wants to open the drawer, he pushes the front panel of the drawer backwards, so that the drawer moves back a small distance (eg, 5mm), and at the same time, the pusher part unlocks the drawer. The user then stops pushing the drawer back, and the pusher component will use the elastic force to bounce the drawer forward for a certain distance. Then the user can manually pull the drawer forward.

When the drawer is closed, the user pushes the drawer backward so that it moves to the rear limit position against the elastic force of the pusher. The user immediately releases the hand, and the drawer bounces forward a short distance under the elastic force of the pusher component to complete the locking of the drawer.

The peculiarity of the refrigerator drawer is that there is an upper cover above it. When the drawer is closed, the upper lid tightly seals the upper opening of the drawer. When the drawer is pulled forward, the upper cover does not move forward with the drawer. During the moving process of the drawer, especially in the early stage of opening or the end of closing, the user experience is seriously affected due to the interference, friction and collision with the upper cover, which may cause the drawer and the upper cover to be loosely sealed, the user's push is blocked, and many problems such as noise are caused. This has also become an important obstacle for the push-pull drawer to be difficult to implement on a large area of the refrigerator.

Utility model content

The refrigerator of the utility model is provided with a pusher-type open and closed drawer, and the upper cover of the drawer is arranged on two sliding rails, and each sliding rail has a slope surface that gradually ascends from the front to the back. When the drawer is closed, when the drawer is pushed back to the rear limit position, the upper cover is pushed back by the drawer and moved along the slope. After the drawer is rebounded forward by the elastic force to be locked on the box body, the upper cover moves forward and downward along the slope under the action of its own gravity, so as to closely abut against the drawer. After the drawer is closed, the upper cover still has a tendency to slide forward and downward due to the function of the slope, so that the drawer can be better sealed. Moreover, since the upper cover is "movable", when the drawer is closed, the upper cover moves backward with the drawer for a certain distance, which can avoid the additional resistance of the upper cover to the backward movement of the drawer, so that the user is more labor-saving. The structure of the utility model is simple, but the function is very practical. And the number of parts is small, the possibility of failure is small, and the reliability is high.

Detailed ways

The refrigerator according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 14 . Among them, the orientation or positional relationship indicated by "front", "rear", "top", "bottom", "top", "bottom", "inside", "outside", "horizontal", etc. are indicated based on the accompanying drawings azimuth or position relationship. As such, it is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

The embodiment of the present utility model 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. Vapor compression refrigeration cycle systems include compressors, condensers, evaporators, throttling devices, and other refrigeration accessories.

In some embodiments, as shown in FIG. 1 , the refrigerator includes a box body 10 and a drawer 300 that can be opened and closed in a push-pull manner inside the box body 10 so as to be pushed and pulled back and forth. A pusher component is disposed between the drawer 300 and the box body 10 . When the drawer 300 is in the closed state, the elastic pusher locks the drawer 300 to the box body 10 . When the user wants to open the drawer 300, the front panel of the drawer 300 is pushed backwards, so that the drawer 300 moves backward by a preset distance (eg 5mm) against the elastic force of the pusher, and at the same time the pusher unlocks the drawer 300. The user then stops pushing the drawer 300 backward, the pusher component will use the elastic force to bounce the drawer 300 forward for a certain distance (for example, 10 cm), and then the user can manually pull the drawer 300 forward. When the user wants to close the drawer 300, he first pushes the drawer 300 backward to make it move to a rear limit position against the elastic force of the pusher (at the rear limit position, the drawer 300 cannot continue to move backward). Under the action of the elastic force of the pusher component, the elastic force of the push-pull component rebounds forward by a preset distance (eg, 5 mm) to complete the locking of the drawer 300 .

The drawer 300 that can be opened and closed by a push-pull is widely used in cabinet drawers and furniture drawers in the prior art. Therefore, the specific structure of the push bomb structure will not be repeated here.

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 will not be described again. As shown in FIG. 2 , the refrigerator may further include two sliding rails 110 and an upper cover 400 . The two sliding rails 110 are respectively arranged on the two side walls of the box body 10 in the lateral direction (ie the left and right directions marked in the figure) and extend front and rear. Each sliding rail 110 is formed with at least one slope surface 1121, 1141. The two lateral ends of the upper cover 400 are respectively placed on the two sliding rails 110 to cover the upper opening of the drawer 300 .

For example, two track plates 100 , 200 may be provided in FIG. 2 . 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 side surface of one rail plate 100 , 200 . The drawer 300 can also be installed on the two track boards 100 and 200 in a forward-rearward push-pull manner. As shown in FIG. 3 and FIG. 9 , the lateral two side walls of the drawer 300 respectively have first sliding rails 390 extending front and rear, and the two rail boards 100 and 200 respectively have second sliding rails 190 extending front and rear. 190 cooperates with a first sliding rail 390 to allow the drawer 300 to be pushed and pulled back and forth.

When the drawer 300 is pushed backward to the rear limit position, the upper cover 400 then moves backward and moves upward along the slope surfaces 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, the upper cover 400 still has a tendency to slide forward and downward due to the function of the slope surfaces 1121 and 1141 , so that the drawer 300 can be better sealed.

The drawer according to the embodiment of the present invention is particularly suitable for the drawer in the dry and wet zones, and the drawer used in the dry zone or the wet zone has higher requirements on tightness.

Since the upper cover 400 is "movable", when the drawer 300 is closed, the upper cover 400 moves backward with the drawer 300 for a certain distance, which can prevent the upper cover 400 from generating additional resistance to the backward movement of the drawer and save the user's effort. The structure of the utility model is simple, but the function is very practical. And the number of parts is small, the possibility of failure is small, and the reliability is high.

In some embodiments, each slide rail 110 is further mounted with a buffer stopper 130 . When the upper cover 400 moves forward and downward along the slope surfaces 1121 and 1141 to a position abutting against the drawer 300 , the movement is stopped by the buffer block 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.

An alternative structure of the slide rail 110 is illustrated in FIGS. 2 to 4 . The figure only illustrates 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.

As shown in FIG. 2 to FIG. 4 , each slide rail 110 has at least one inner recess 112 , 114 recessed downward, and the rear surfaces of the inner recesses 112 , 114 form slopes 1121 , 1141 . Each lateral end of the upper cover 400 has at least one mounting post 410, 420 extending laterally, the number of the mounting posts 410, 420 is the same as the number of the inner recesses 112, 114, and each mounting post 410, 420 is located in one inner recess 112 and 114. In addition to forming slopes 1121, 1141 on the rear surfaces of the recesses 112, 114, another function of the recesses 112, 114 is to constrain the positions of the mounting posts 410, 420 unless the mounting posts 410, 420 are subjected to a sufficient force to pass over the recesses 112, 114. 114, otherwise 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 forward frictional force of 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.

The surfaces of the inner recesses 112 and 114 are arc-shaped, so as to facilitate design and processing. Of course, it can also be made into other curved surfaces. Both 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 small, and it is convenient to cooperate with the slope surfaces 1121 and 1141 .

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

Further, as shown in FIG. 2 to FIG. 4 , among the two slope surfaces 1121 and 1141 of each slide rail 110 , the slope of the slope surface 1141 located on the rear side is greater than that of the slope surface 1121 located on the front side, for example , when the inner recesses 112 and 114 are arc-shaped, the radius of the rear inner recess 114 is made smaller than the radius of the front inner recess 112 . This makes the rear slope 1141 steeper, and the rear end of the upper cover 400 is lifted upward when it is moved backward, which can facilitate the subsequent movement of the upper cover 400 along the slopes 1121 and 1141 more smoothly forward and downward, making it more closely Abutting on the drawer 300, the sealing performance is better.

As shown in FIG. 3 , the buffer stopper 130 of each slide rail 110 may be disposed in the inner recess 112 on the front side to block the front mounting post 410 of the upper cover 400 . Since the upper cover 400 is light in weight, only one buffer stopper 130 is provided to complete the buffering of the upper cover 400 , and the structure is simpler.

The following describes the closing process of the drawer 300 in the embodiment of the present invention with reference to FIGS. 2 to 8 .

2 to 4 illustrate the open state of the drawer 300 . At this time, the mounting post 410 is located in the inner recess 112 , and the forward movement path is blocked by the buffer stopper 130 . The mounting post 420 is located within the inner recess 114 .

Then, the rear limit position of the drawer 300 is pushed backward, that is, from the states of FIGS. 2 to 4 to the states of FIGS. 5 and 6 . The installation column 410 moves up along the slope 1121 , and the installation column 420 moves up along the slope 1141 . Because of the two slope surfaces 1121 and 1141 , the slope of the slope surface 1141 is larger, so that the rear end of the upper cover 400 is lifted upwards.

Finally, when the user releases the drawer 300 , the drawer 300 springs forward by a preset distance, and is then locked to the box body 10 . During this process, under the gravity of the upper cover 400, the mounting column 410 slides forward and downward along the slope 1121, and the mounting column 420 slides forward and downward along the slope 1141, and finally reaches the figure shown in FIG. 7 and FIG. 8 . The state in which the drawer 300 has completed being closed.

In some embodiments, as shown in FIG. 2 , FIG. 3 , FIG. 4 and FIG. 9 , each slide rail 110 also has a top plate 120 extending parallel to the slide rail 110 above each slide rail 110 , and each mounting post 410 , 420 is located on the slide rail 110 . and the top plate 120. The sliding rail 110 and the top plate 120 form a sliding groove structure to better constrain the mounting posts 410 and 420 . When the rail plates 100 and 200 are provided, the top plate 120 may be extended from the inner surface of the rail plates 100 and 200 .

Notches 121 and 123 corresponding to the concave parts 112 and 114 can be formed on the top plate 120 , so that when the upper cover 400 is taken out upward, the notches 121 and 123 make room 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. The opening 125 formed between the top plate 120 and the front end of the side plate enables the user to pull out the upper cover 400 from the front side of the slide rail 110 .

In some embodiments, as shown in FIGS. 10 to 12 , the refrigerator further includes a sealing strip 500 extending along the lateral direction of the upper cover 400 . The weather strip 500 may generally include a mounting portion 510 and a sealing portion 530 . 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 the sealing portion 530 is gradually bent downward while extending forward, which is a one-way bending. When the drawer 300 is moved backward, the sealing portion 530 is pushed back by the front panel of the drawer 300 and elastically deformed, thereby sealing the gap between the front end of the upper cover 400 and the front panel of the drawer 300 , thereby achieving the effect of sealing and heat insulation. For better deformation, the sealing portion 530 may be made of a sealing material with greater elasticity.

The research and development personnel have verified through many experiments that the curved structure of the sealing portion 530 is easier to elastically deform, so that when the drawer 300 is pushed back, the resistance of the sealing strip 500 is less, and the user presses the drawer 300 more effortlessly, and the experience is very good.

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 bend upward gradually at the same time, and this structure will not be repeated herein.

As shown in FIG. 12 , the curvature of the sealing portion 530 can be gradually increased from the rear to the front, which can be more conducive to the stress deformation of the sealing portion 530 , so that pushing the drawer 300 backward is more labor-saving.

In some embodiments, the weather strip 500 further includes a support portion 520 . The support portion 520 is made of a hard material (eg, 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 part 530 is pushed back so that its front end contacts the supporting part 520 , the supporting part 520 supports the sealing part 530 , and forms a heat-insulating cavity with the sealing part 530 .

After the sealing portion 530 is elastically deformed to a certain degree by the pusher 300 , the sealing portion 530 is supported by the supporting portion 520 , which can prevent the elastic deformation of the sealing portion 530 from being too large and affecting its service life. In addition, the thermal insulation cavity formed between the sealing part 530 and the supporting part 520 can enhance the thermal insulation performance of the sealing strip 500 .

In some embodiments, as shown in FIG. 12 , the front end of the upper cover 400 has a slot 450 whose front side is open. In the middle of the slot 450 there is a plug board 453 which separates the inner space of the slot 450 up and down. The rear end of the mounting portion 510 has a rearward opening groove 511 , the mounting portion 510 is inserted into the slot 450 , and the insertion 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 manner, which is very convenient for installation and removal.

Further, the top wall and the bottom wall of the groove 511 can respectively extend out elastic locking teeth 5112 which are gradually inclined forward. After the mounting portion 510 is inserted into the slot 450 , the elastic locking teeth 5112 are elastically deformed by the insertion plate 453 , and adhere to the insertion plate 453 by the elastic force, thereby making the position of the mounting portion 510 more stable.

In some embodiments, as shown in FIGS. 13 and 14 , 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 the front panel of the drawer.

The drawer body 310 is used for storage. As shown in FIG. 13 , the drawer body 310 includes a bottom plate 311 , two side plates 312 and a back plate 313 . Wherein, the bottom plate 311 is used for carrying articles. The two side plates 312 extend upward from both 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 with the two side panels 312 . For example, the front frame 330 and the side plate 312 can be connected by screws through the screw holes 302 and the screw holes 305 .

The front frame 330 is vertically installed on the front side of the drawer body 310 and is made of 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 .

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

Due to the relatively high rigidity of the metal frame and the glass panel, when the user pushes the drawer 300, the drawer 300 will be deformed very little, and the sliding rail 110 of the drawer 300 and the sliding rail 110 of the box body 10 will not be affected by the deformation due to the mutual sliding. The drawer 300 is made to slide back and forth smoothly, and the user is very labor-saving.

As shown in FIG. 13 and FIG. 14 , both the front frame 330 and the glass panel 320 are 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 that are detachably connected. 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 , respectively. Two ends of the bottom edge 334 are connected to the bottom ends of the two side edges 3322 respectively.

By now, those skilled in the art will recognize that although various exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, Numerous other variations or modifications consistent with the principles of the present invention are directly identified or derived from the disclosure of the present invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
