Description

refrigerator

technical field

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

Background technique

Drawers are very important storage structures in refrigerators. In a general refrigerator, drawers are provided in the freezer compartment, the changing room, and the refrigerator compartment. Moreover, in order to realize the isolation and airtight storage of storage items, many drawers are equipped with upper covers.

Most of the existing refrigerators require the user to pull out the drawer as a whole, and then manually open the upper cover. This form makes the user operation more complicated and the user experience is not high.

In some improved structures, when the user pulls out the drawer, the upper cover is fixed by other structures in the refrigerator and does not move forward with the drawer. In this way, the process of the user pulling out the drawer is also a process in which the upper cover gradually opens the drawer opening, so that the user does not need to manually open the upper cover. However, such a solution that the upper cover does not move makes it impossible to arrange some functional display and control structures on the upper cover, which seriously restricts the intelligent design of the drawer. At the same time, it is also difficult to design the appearance of the drawer based on the upper cover.

Utility model content

One purpose of the present utility model is to solve the above-mentioned defects in the prior art, and to provide a refrigerator whose upper cover can be automatically half-opened along with the drawer.

The further object of the present invention is to make the realization of the relevant structure of the automatic half-opening of the upper cover simple and reliable.

In particular, the utility model provides a refrigerator, which includes:

Front open box;

a drawer, which can be pushed and pulled back and forth in the box; and

The upper cover is arranged in the box so as to be able to move forward and backward, and is used to cover the upper opening of the drawer; the refrigerator is configured such that when the drawer is moved forward and pulled out from the inside of the box, the upper cover is first driven to move forward synchronously to a stop position Afterwards, disengage the top cover from the drawer and stop at the stop position, and then let the drawer continue to move forward independently.

Optionally, the refrigerator also includes two sliding rails, which are respectively disposed on the lateral two side walls of the box body for supporting the lateral ends of the upper cover, and each sliding rail has at least one slope surface that gradually slopes upward from the rear to the front. ; And the upper cover moves up along the slope surface gradually to be separated from the drawer before moving forward with the drawer to the stop position.

Optionally, each sliding rail surface forms a plurality of slope surfaces arranged in front and back; and each lateral side end of the upper cover extends a plurality of legs, and the plurality of legs are placed on the corresponding sliding rails and are in line with the plurality of slope surfaces. A match is made to gradually move each leg up along the corresponding ramp surface as the drawer moves forward.

Optionally, a stop groove is formed on the surface of each slide rail, which is disposed adjacently in front of a slope surface, so as to allow the foot passing over the slope surface to enter the stop groove, so that the upper cover reaches the stop position.

Optionally, the stop groove on each slide rail is located in front of the frontmost slope surface of the slide rail.

Optionally, among the plurality of legs on each side end of the upper cover, at least the legs corresponding to the stopper grooves are sleeved with rollers, so as to facilitate the legs to escape from the stopper grooves when the drawer moves backwards.

Optionally, each slide rail has two ramp surfaces; and each lateral side end of the upper cover has two legs.

Optionally, the surface of each slide rail includes: a first horizontal segment; a rear slope surface inclined forward and upward from the front end of the first horizontal segment; a second horizontal segment extending forward from the front end of the slope surface; A vertical section extending downward from the front end of the second horizontal section; a third horizontal section extending forward from the front end of the vertical section; a sloped surface on the front side that slopes forward and upward from the front end of the third horizontal section; a sloped surface from the front side a fourth horizontal segment extending forward from the rear end; and a stop groove located in front of the fourth horizontal segment.

Optionally, the top edges of the two lateral side walls of the drawer respectively have positioning grooves; the bottom surface of the upper cover has two positioning protrusions, and when the upper cover is in the state of covering the drawer, each positioning protrusion is located in the corresponding positioning groove. , to allow the drawer to move the top cover back and forth.

Optionally, the top edges of the two lateral side walls of the upper cover start from the positioning groove, and gradually extend backward and downward to form a guiding inclined surface, so that when the drawer is moved backward and closed, the positioning protrusion is introduced into the positioning groove by the guiding inclined surface.

Detailed ways

The refrigerator according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 7 . 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. Refrigerators can be refrigerated using a vapor compression refrigeration cycle system to provide cooling capacity. Vapor compression refrigeration cycle systems include compressors, condensers, evaporators, throttling devices, 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 box body 900 and a drawer 100 . The drawer 100 can be pushed and pulled back and forth in the box. Of course, in addition to the drawer 100, the refrigerator may also include other drawers and door bodies, such as the drawer 700 and the door body 800, which will not be described in detail herein.

FIG. 2 is a schematic diagram of the state of a drawer in a refrigerator according to an embodiment of the present invention when it is closed; FIG. 3 is a schematic diagram of the state of the drawer shown in FIG. 2 after the drawer is moved forward and opened.

As shown in FIG. 2 to FIG. 4 , the refrigerator according to the embodiment of the present invention further includes an upper cover 400 . The upper cover 400 is disposed in the box body 900 in a forward-backward translational manner, and is used to cover the upper opening of the drawer 100 so as to form a relatively sealed storage space inside the drawer 100 .

In FIG. 2, the drawer 100 is inside the box 900, or 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 moved forward and pulled out from the inside of the box body 900, the upper cover 400 is driven to move forward synchronously to a stop position, and then the upper cover 400 is separated from the drawer 100 and stays at the stop position (In FIG. 3 , the upper cover 400 is at the stop position), and then the drawer 100 is allowed to move forward independently to continue to open, for example, to finally move to the fully pulled-out position shown in FIG. 3 . But at this time, the upper cover 400 is in a half-open state.

After completing the operation of accessing the items, the user pushes the drawer 100 backward. Initially, the drawer 100 moves backwards but the upper cover 400 does not move. After the upper cover 400 completely covers the upper opening of the drawer 100, the drawer 100 drives the upper cover 400 to move backward together until the initial closed position shown in FIG. 2 .

The embodiment of the utility model realizes the "automatic half-opening" function of the drawer. After the user pulls out the drawer, the upper cover is in a half-open state, and the opening exposed by the drawer 100 is large enough. Referring to FIG. Moreover, the opening process of the entire drawer 100 is also very novel and unique, which makes the refrigerator more high-grade and has a better user experience. Moreover, after the user pulls out the drawer 100, the upper cover 400 is also partly pulled out, and the designer can design some display control structures on the top front of the upper cover 400, such as an interface for adjusting and displaying the temperature and humidity inside the drawer 100, or adjusting the temperature and humidity to further enhance the intelligence level of the refrigerator.

FIG. 4 is an enlarged view of part A of the structure shown in FIG. 3 , and FIG. 5 is an exploded schematic view of the structure shown in FIG. 2 . In some embodiments, as shown in FIGS. 2-4 , the refrigerator may include two slide rails 210 . The two sliding rails 210 are respectively disposed on the two lateral side walls of the box body 900 (the lateral direction refers to the left and right directions marked in the figure) for supporting the lateral ends of the upper cover 400 . The side wall of the box body 900 can be directly concave inward to form a groove, and the bottom wall of the groove can form a sliding rail. As shown in FIG. 2 , two separately processed rail members 200 may be provided, and the rail members 200 may be installed on the lateral side walls of the box body 900 . The aforementioned sliding rail 210 is formed on the rail member 200 . Figures 2-4 omit the case 900 to more clearly show other components.

Each slide rail 210 has at least one slope surface, such as slope surfaces 212 and 214 , which is gradually inclined upward from rear to front. The upper cover 400 moves up gradually along the slope surfaces 212 and 214 to be separated from the drawer 100 before the drawer 100 moves forward to the stop position.

For example, as shown in FIG. 2 to FIG. 5 , the surface of each slide rail 210 forms a plurality of slope surfaces 212 and 214 arranged in front and back. The multiple slope surfaces can dispersely bear the gravity of the upper cover 400 , so that the movement of the upper cover 400 is smoother. Correspondingly, each lateral side end of the upper cover 400 extends a plurality of support legs 410 and 420 , 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 the corresponding one of the sliding rails 210 one by one. When the drawer 100 moves forward, each support foot 410 , 420 gradually moves upward along the corresponding slope surface 212 , 214 . In this embodiment, the upper cover 400 is only mounted on the slide rail 210 through the extended legs 410 and 420 to form a multi-point support. If the two ends of the upper cover 400 are directly placed on the two slide rails 210, two surfaces are supported. In contrast, the use of multi-point support undoubtedly reduces the contact area between the small upper cover 400 and the slide rail 210 , so that the friction area between the two is reduced, which is beneficial for the upper cover 400 to slide back and forth on the slide rail 210 . Moreover, using the plurality of legs 410, 420 and the plurality of slope surfaces 212, 214 for cooperation also simplifies the design work. Because, if the two ends of the upper cover 400 are directly placed on the two sliding rails 210, it is difficult for the designer to design a structure on the upper cover 400 that cooperates with the two slope surfaces 212 and 214 of the sliding rails 210. The complex structure will also increase the processing cost.

In some embodiments, as shown in FIG. 2 to FIG. 5 , a blocking groove 219 is formed on the surface of each slide rail 210 . The stop groove 219 is disposed in front of and adjacent to a sloped face. When the drawer 100 drives the upper cover 400 to move forward, the support feet move along the slope, then cross the slope, and then enter the stop groove 219 . The support foot is restricted in the stop groove 219 and cannot continue to move, that is, the upper cover 400 cannot continue to move. Thus, the drawer 100 can be moved forward independently. In other words, after the feet enter the stopper groove 219, the upper cover 400 reaches the aforementioned stop position.

The number of the blocking grooves 219 may be one or multiple. When there is one stopper groove 219 , the stopper groove 219 on each slide rail 210 can be located in front of the frontmost slope surface 212 of the slide rail 210 , as shown in FIG. 5 . This is because when the drawer 100 is moved backward to close the drawer 100 , the support feet 410 also need to be disengaged from the stop grooves 219 . The purpose of setting the position as far forward as possible is to facilitate the force applied by the drawer 100 to the legs 410 of the upper cover 400 and prevent the legs 410 from being caught by the blocking grooves 219 . Further, among the plurality of legs 410 and 420 on each side end of the upper cover 400 , at least the legs 410 corresponding to the stop grooves 219 are sleeved with rollers 413 . When the drawer 100 moves backwards, the rollers 413 roll backwards in the stopper groove 219 , which can facilitate the support feet 410 to escape from the stopper groove 219 . For the support feet 420 without rollers, it is preferable to make the lower surface of the support feet 420 to be curved, so as to facilitate the sliding on the sliding rails 210 . Of course, all the supporting feet 410 and 420 can also be sleeved with rollers.

In addition, the transition between the stop groove 219 and the ramp surfaces 212 and 214 should also be smooth enough to facilitate the movement of the feet 410 and 420 .

FIG. 5 illustrates an alternative structure of the slide rail 210 with two ramp surfaces 212 , 214 and a stop groove 219 . As shown in FIG. 5 , optionally, the surface of each slide rail 210 includes: a first horizontal section 211 ; a rear slope surface 214 inclined forward and upward from the front end of the first horizontal section 211 , and a slope surface 214 from the slope surface 214 The front end of the second horizontal section 213 extends forward, the vertical section 215 extends downward from the front end of the second horizontal section 213, and the third horizontal section 216 extends forward from the front end of the vertical section 215. 216 A front slope 212 whose front end slopes forward and upward, a fourth horizontal section 217 extending forward from the rear end of the front slope 212 , and a stop groove 219 located in front of the fourth horizontal section 217 . Rounded corners are used for smooth transition between each two adjacent sections, so that the movement of the support feet 410 and 420 thereon is smoother and labor-saving.

In some embodiments, due to the gravity of the upper cover 400 itself, when the drawer 100 moves forward or backward, the upper cover 400 can move with the drawer 100 only by the static friction force with the top edge of the side wall of the drawer 100 . However, it is difficult to guarantee the accuracy of the position of the upper cover 400, and unnecessary dislocation may occur during the movement.

FIG. 6 is a schematic diagram of the bottom structure of the upper cover 400 . In some embodiments, as shown in FIG. 5 and FIG. 6 , the top edges of the two lateral side walls of the drawer 100 are provided with positioning grooves 120 respectively. The bottom surface of the upper cover 400 has two positioning protrusions 440 . When the upper cover 400 is in the state of covering the drawer 100, each positioning protrusion 440 is located in the corresponding positioning groove 120, so as to allow the drawer 100 to drive the upper cover 400 to move back and forth, and make the movement of the upper cover 400 more accurate, preventing the Unnecessary misalignment. Both the positioning groove 120 and the positioning protrusion 440 are preferably arc-shaped structures, and the surface of the positioning groove 120 and the adjacent surface of the top edge of the side wall of the drawer 100 are preferably rounded transitions. The purpose of this setting is to facilitate the positioning protrusion 440 when necessary. The positioning groove 120 is removed smoothly.

When the drawer 100 is in the closed position shown in FIG. 2 , the positioning protrusion 440 is located in the positioning groove 120 . During the forward movement of the drawer 100 from the state shown in FIG. 2 , the legs 410 and 420 of the upper cover 400 are gradually moved upward along the slope surfaces 212 and 214 respectively, so that the positioning protrusion 440 is gradually moved upward to disengage from the positioning groove 120 , so that the upper cover 400 is moved upward gradually. The drawer 100 is disengaged to allow the drawer 100 to move forward on its own.

FIG. 7 is a state diagram of the drawer 100 in the process of moving backward and closing. 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 gradually extend backward and downward to form a guide slope 130 . When the drawer 100 is moved backward and closed, the guide slope 130 gradually moves backward relative to the positioning protrusion 440 until it contacts the bottom end of the positioning protrusion 440 , and then continues to move backward to introduce the positioning protrusion 440 into the positioning groove 120 .

At the same time, during the backward movement of the drawer 100 , the guide slope 130 lifts the positioning protrusion 440 upward, so that the support feet 410 move upward to disengage from the stop 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 present invention is very ingenious, but the function is very practical. And the number of parts is small, the possibility of failure is small, and the reliability is high.

It can be understood that the refrigerator of the present invention may include one set of the above-mentioned drawers, upper covers and sliding rails, and may also include multiple sets.

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.
