Detailed Description

A refrigerator according to an embodiment of the present invention is described below with reference to fig. 1 to 7. 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 refrigerator can adopt a vapor compression refrigeration cycle system for refrigeration to provide cold energy. The vapor compression refrigeration cycle system includes a compressor, a condenser, an evaporator, a throttling device, and other refrigeration accessories.

Fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. As shown in fig. 1, a refrigerator generally includes a cabinet 900 and a drawer 100. The drawer 100 is provided in the cabinet to be pushed and pulled back and forth. Of course, besides the drawer 100, the refrigerator may further include other drawers and doors, such as the drawer 700 and the door 800, which are not described in detail herein.

Fig. 2 is a schematic view illustrating a state in which a drawer in a refrigerator according to an embodiment of the present invention is closed; fig. 3 is a schematic view of the drawer of fig. 2 shown in a state of being moved forward and opened.

As shown in fig. 2 to 4, the refrigerator according to the embodiment of the present invention further includes an upper cover 400. The upper cover 400 is translatably disposed in the case 900 back and forth to cover the upper opening of the drawer 100, so that a relatively sealed storage space is formed inside the drawer 100.

In FIG. 2, the drawer 100 is inside the cabinet 900, otherwise referred to as being in a closed position. At this time, the upper cover 400 completely covers the upper opening of the drawer 100. In the embodiment of the present invention, when the drawer 100 is pulled out from the inside of the box 900 by forward movement, the upper cover 400 is driven to move forward to a stop position, the upper cover 400 is separated from the drawer 100 and stops at the stop position (in fig. 3, the upper cover 400 is in the stop position), and then the drawer 100 alone continues to move forward to continue to be opened, for example, finally moves to the complete pull-out position shown in fig. 3. However, at this time, the upper cover 400 is in a half-open state.

After the operation of accessing the article is completed, the user pushes the drawer 100 backward. Initially, the drawer 100 moves backward but the upper lid 400 does not move until the upper lid 400 completely covers the upper opening of the drawer 100, and then the drawer 100 moves backward together with the upper lid 400 until the initial closed position shown in fig. 2.

The embodiment of the utility model provides an "automatic half-open" function of drawer has been realized. After the user pulls the drawer open, the upper cover is in a half-open state, and the opening of the drawer 100 is large enough, referring to fig. 3, the requirement of the user for storing and taking articles can be basically met, and the trouble of opening the cover of the user is avoided. Moreover, the opening process of the whole drawer 100 is novel and unique, so that the refrigerator is more excellent in grade and better in user experience. Moreover, after the user pulls out the drawer 100, the upper cover 400 is also pulled out partially, and a designer can design some display and control structures on the front portion of the top surface of the upper cover 400, such as an interface for adjusting and displaying the temperature and humidity inside the drawer 100, or buttons or keys for adjusting the temperature and humidity, and the like, so as to further improve the intelligent level of the refrigerator.

Fig. 4 is an enlarged view of the structure shown in fig. 3 at a, and fig. 5 is an exploded view of the structure shown in fig. 2. In some embodiments, as shown in fig. 2-4, the refrigerator may include two slide rails 210. The two slide rails 210 are respectively disposed on two lateral sidewalls (lateral direction refers to the left and right direction marked in the figure) of the box 900 for supporting two lateral ends of the upper cover 400. The side wall of the box 900 can be directly inwards concave to form a groove, and the bottom wall of the groove forms a sliding rail. Alternatively, as shown in fig. 2, two separately machined rail members 200 may be provided, and the rail members 200 may be mounted on the lateral side walls of the cabinet 900. The rail member 200 is formed with the aforementioned slide rail 210. The box 900 is omitted from fig. 2-4 to more clearly show the other components.

Each slide rail 210 has at least one ramp surface, such as ramp surfaces 212, 214, that is gradually inclined upward from rear to front. The lid 400 is gradually moved upward along the ramp surfaces 212, 214 to disengage the drawer 100 as the drawer 100 is moved forward to the rest position.

For example, as shown in fig. 2 to 5, a plurality of slope surfaces 212 and 214 are formed on the surface of each slide rail 210. The plurality of slope surfaces can disperse and bear the gravity of the upper cover 400, so that the upper cover 400 can move more smoothly. Correspondingly, a plurality of

support legs

410 and 420 extend from each lateral side end of the upper cover 400, and the number of the

support legs

410 and 420 is the same as that of the slope surfaces 212 and 214.

All the

legs

410, 420 of each lateral side end of the upper cover 400 are matched with all the slope surfaces 212, 214 of a corresponding one of the slide rails 210 one by one. As the drawer 100 advances, each

leg

410, 420 gradually moves up along the corresponding

ramp surface

212, 214. In this embodiment, the top cover 400 is mounted to the slide rail 210 only by the extending

legs

410, 420, thereby forming a multi-point support. If the two ends of the upper cover 400 are directly connected to the two sliding rails 210, two surface supports are formed. In contrast, the multipoint support is adopted to clearly reduce the contact area between the upper cover 400 and the slide rail 210, so that the friction area between the upper cover 400 and the slide rail 210 is reduced, and the upper cover 400 can slide back and forth on the slide rail 210. Moreover, the use of

multiple legs

410, 420 in cooperation with multiple ramp surfaces 212, 214 also makes the design task simpler. Because, if the two ends of the upper cover 400 are directly connected to the two slide rails 210, it is difficult for a designer to design a structure on the upper cover 400 to match the two

slope surfaces

212 and 214 of the slide rails 210, and even if the design is complicated, the manufacturing cost is increased.

In some embodiments, as shown in fig. 2 to 5, a stop groove 219 is formed on the surface of each slide rail 210. The stopper groove 219 is disposed forward of and adjacent to a slope surface. When the drawer 100 carries the upper cover 400 forward, the legs move up along the slope and then pass over the slope, and then enter the stopping groove 219. The legs are restrained from further movement within the stop slots 219, i.e., the upper cover 400 cannot be further moved. Thereby allowing the drawer 100 to be moved forward by itself. In other words, after the legs enter the stopping grooves 219, the upper cover 400 reaches the aforementioned stopping position.

The number of the stopper grooves 219 may be one or more. When there is one stop groove 219, the stop groove 219 of each slide rail 210 may be located in front of the slope surface 212 at the foremost side of the slide rail 210, as shown in fig. 5. This is because it is also necessary to disengage the legs 410 from the stopping grooves 219 when the drawer 100 is closed by moving it backward. The front position is set as far as possible to facilitate the force of the drawer 100 on the legs 410 of the upper cover 400 and to prevent the legs 410 from being caught by the catching grooves 219. Further, among the

legs

410, 420 of each side end of the upper cover 400, at least the leg 410 corresponding to the stopping groove 219 is sleeved with a roller 413. When the drawer 100 is moved rearward, the roller 413 rolls rearward in the stopping groove 219 to facilitate the leg 410 to be disengaged from the stopping groove 219. For the support legs 420 without rollers, the lower surface is preferably cambered to facilitate sliding on the sliding rails 210. Of course, the rollers can be sleeved on all the supporting

legs

410 and 420.

In addition, the transition between the stop slot 219 and the ramp surfaces 212, 214 should also be smooth enough to facilitate movement of the

legs

410, 420.

Fig. 5 illustrates an alternative configuration of the slide rail 210 that contemplates two

ramp surfaces

212, 214 and a stop slot 219. As shown in fig. 5, optionally, the surface of each slide rail 210 includes: a first horizontal segment 211; a rear-side sloped surface 214 sloped forward and upward from a front end of the first horizontal section 211, a second horizontal section 213 extending forward from the front end of the sloped surface 214, a vertical section 215 extending downward from a front end of the second horizontal section 213, a third horizontal section 216 extending forward from a front end of the vertical section 215, a front-side sloped surface 212 sloped forward and upward from a front end of the third horizontal section 216, a fourth horizontal section 217 extending forward from a rear end of the front-side sloped surface 212, and a stopper groove 219 located in front of the fourth horizontal section 217. The two adjacent sections are in round smooth transition, so that the supporting

legs

410 and 420 can move on the supporting legs more smoothly and labor-saving.

In some embodiments, since the upper cover 400 has its own weight, when the drawer 100 moves forward or backward, the upper cover 400 can move with the drawer 100 only by virtue of the static friction with the top edge of the side wall of the drawer 100. However, this makes it difficult to ensure the positional accuracy of the upper cover 400, and an unnecessary misalignment may occur during the movement.

Fig. 6 is a schematic bottom structure view of the upper cover 400. In some embodiments, as shown in fig. 5 and 6, the drawer 100 has two side walls with positioning slots 120 at the top edges of the two side walls. The bottom surface of the upper cover 400 is provided with two positioning protrusions 440. When the upper cover 400 is in a state of covering the drawer 100, each positioning protrusion 440 is located in the corresponding positioning groove 120 to allow the drawer 100 to drive the upper cover 400 to move back and forth, and to make the movement of the upper cover 400 more accurate, thereby preventing unnecessary misalignment. The detent 120 and the detent projection 440 are preferably arcuate in configuration, and the surface of the detent 120 preferably transitions with a radius from the adjacent surface of the top edge of the side wall of the drawer 100 in order to facilitate the detent projection 440 disengaging from the detent 120 more smoothly when necessary.

When the drawer 100 is in the closed position shown in fig. 2, the detent projection 440 is located within the detent 120. During the forward movement of the drawer 100 from the state of fig. 2, the

legs

410, 420 of the upper cover 400 gradually move upward along the ramp surfaces 212, 214, respectively, so that the positioning protrusion 440 gradually moves upward to disengage from the positioning slot 120, so that the upper cover 400 disengages from the drawer 100, allowing the drawer 100 to move forward alone.

Fig. 7 is a schematic view of the drawer 100 during the rearward movement closing process. As shown in fig. 7, the top edges of the two lateral side walls of the upper cover 400 start from the positioning groove 120 and extend rearward and gradually downward to form the guide slopes 130. When the drawer 100 is moved backward and closed, the guide slope 130 is gradually moved backward relative to the positioning protrusion 440 until contacting the bottom end of the positioning protrusion 440, and then the positioning protrusion 440 is introduced into the positioning groove 120 by further moving backward.

Meanwhile, during the backward movement of the drawer 100, the guide slope 130 lifts the positioning protrusion 440 upward, so that the leg 410 moves upward to be disengaged from the stopping groove 219, so that the upper cover 400 can move backward with the drawer 100.

The matching structure of the sliding rail 210, the upper cover 400 and the drawer 100 of the utility model is very ingenious, but the function is very practical. And the number of parts is less, the possibility of failure is low, and the reliability is high.

It can be understood that the refrigerator of the present invention may include a set of the above-mentioned drawer, the upper cover and the slide rail, and may also include a plurality of sets.

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.
