Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a refrigerator drawer door and a refrigerator having the same. Background Technology

[0002] Due to factors such as negative pressure, sliding rail self-locking force, door seal suction, and load weight, the opening force of a refrigerator's drawer-type freezer door is 60-70N. Although this meets the standard, it still requires a lot of effort for users, especially the elderly or women.

[0003] Among the related technologies, solutions to reduce the pressure on drawer-type freezer doors include mechanical assistance at the handle, negative pressure release at the bottom of the trim strip, negative pressure release for the door liner and door seal, and negative pressure release for the drain pipe. Although there are many solutions, the opening force is mostly above 50N, and the manufacturing cost of various labor-saving solutions is relatively high.

[0004] In view of this, it is necessary to provide a refrigerator drawer-type door to solve the above-mentioned technical problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a refrigerator drawer-type door, which includes a door liner, a door seal strip disposed circumferentially on the door liner; a first decorative strip located on both sides of the door liner along a first direction, the first decorative strip having a door liner overlapping surface, the door liner overlapping surface extending obliquely along the height direction, and the door liner fitting against the door liner overlapping surface.

[0006] As a further improvement of the present invention, the first trim strip includes a side panel, a first flange connected to the front edge of the side panel, and a second flange connected to the rear edge of the side panel, wherein the door lining overlap surface is located on the second flange.

[0007] As a further improvement of the present invention, the second flange is inclined along the height direction to form the door liner overlap surface.

[0008] As a further improvement of the present invention, the second flange has a gradually changing thickness along the height direction to form the door liner overlap surface.

[0009] As a further improvement of the present invention, the first trim strip also includes a limiting plate connecting the side plate and the second flange, and a step portion is formed between the second flange and the limiting plate.

[0010] As a further improvement of the present invention, one end of the second flange along the height direction is flush with the limiting plate, and the other end is located on the side of the limiting plate facing the first flange.

[0011] As a further improvement of the present invention, the maximum height of the step portion is 1-2 mm.

[0012] As a further improvement of the present invention, the door liner is provided with a mounting groove in the circumferential direction, and the door seal is installed in the mounting groove.

[0013] As a further improvement of the invention, it also includes handles and a second trim strip located at the top and bottom of the door liner, respectively, with the overlapping surface of the door liner extending obliquely toward the handles along the height direction.

[0014] As a further improvement of the present invention, the handle is located on the top of the door liner, and the handle includes a handle body and a gripping part, with a gripping space formed between the handle body and the gripping part.

[0015] As a further improvement of the invention, it also includes slide rails fixed to both sides of the door liner along a first direction, the slide rails being located on the side of the door liner closer to the handle.

[0016] The present invention also provides a refrigerator, which includes the drawer-type door described above.

[0017] The beneficial effects of the present invention are as follows: The present invention limits the tilt angle of the door liner by the tilt angle of the overlapping surface of the door liner, so that there is a gap difference between the door liner and the refrigerator body when the door is closed, thereby creating a difference in door sealing suction between the door liner and the refrigerator body, effectively reducing the opening force.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0039] like Figures 1 to 8 As shown, the refrigerator drawer-type door provided by the present invention includes a door liner 100, two sets of first decorative strips 200, a handle 300, a second decorative strip 400, and a front panel 600. The first decorative strips 200, the handle 300, and the second decorative strips 400 are connected to form a door frame. The front panel 600 is connected to the front side of the door frame, and the door liner 100 is connected to the rear side of the door frame. Foam is applied between the door liner 100 and the front panel 600 to form the drawer-type door. In this invention, for ease of description, the left-right direction of the refrigerator is defined as the first direction.

[0040] The door liner 100 is located on the side of the door frame facing the interior of the refrigerator. The door liner 100 has a rectangular structure and a door seal 101 is provided around its circumference. The door seal 101 is used to seal the gap between the door and the refrigerator body when the door is closed, so that the door fits tightly against the refrigerator body, thereby preventing cold air leakage. The door seal 101 is made of a soft material.

[0041] The door liner 100 has an installation groove 102 around its outer edge. The door seal 101 is installed in the installation groove 102. The door seal 101 and the installation groove 102 are interference fit, thereby ensuring the installation firmness of the door seal 101.

[0042] The first trim strip 200 is located on both sides of the door liner 100 along the first direction, that is, the two sets of the first trim strip 200 are the left trim strip and the right trim strip respectively. The left trim strip and the right trim strip have the same shape and are arranged opposite to each other. The first trim strip 200 has a door liner overlapping surface 201. The door liner 100 is attached to the door liner overlapping surface 201. The door liner overlapping surface 201 extends obliquely along the height direction. Thus, the door liner 100 attached to the door liner overlapping surface 201 also has a certain tilt angle in the height direction.

[0043] The door liner 100 has fitting areas on both sides along the first direction that fit with the door liner overlapping surface 201. By fitting the fitting areas of the door liner 100 to the door liner overlapping surface 201 of the first trim strip 200, the tilt angle of the door liner 100 is defined by the tilt angle of the door liner overlapping surface 201.

[0044] When the door liner 100 has a certain tilt angle, and the door is closed, the upper gap between the door liner 100 and the refrigerator body is large and the lower gap is small. This results in the door seal 101 located at the upper part of the door liner 100 experiencing less pressure than the door seal 101 located at the lower part of the door liner 100. In other words, the door seal 101 located at the lower part of the door liner 100 fits more tightly with the refrigerator body, and the door seal suction is stronger. Alternatively, the upper gap between the door liner 100 and the refrigerator body is small and the upper gap is large, resulting in the door seal 101 located at the upper part of the door liner 100 experiencing greater pressure than the door seal 101 located at the lower part of the door liner 101. In other words, the door seal 101 located at the upper part of the door liner 100 fits more tightly with the refrigerator body, and the door seal suction is stronger.

[0045] Thus, when the door is opened, the upper or lower side of the door (the side with the larger gap from the refrigerator body) can open first, allowing outside air to enter the refrigerator body to balance the pressure inside and outside the refrigerator body, thereby reducing the opening force when opening the lower or upper side of the door (the side with the smaller gap from the refrigerator body); at the same time, the door body is sealed and attracted to the refrigerator body on all four sides by the door seal 101, and not opening the upper and lower sides of the door body at the same time can disperse the door seal suction force to achieve the effect of reducing the opening force.

[0046] The first trim strip 200 includes a side panel 202, a first flange 203 connected to the front edge of the side panel 202, and a second flange 204 connected to the rear edge of the side panel 202. The door liner overlapping surface 201 is located on the second flange 204, and the side of the second flange 204 facing the door liner 101 is the door liner overlapping surface 201.

[0047] The first flange 203 is used to abut against the front panel 600 located on the front side of the door frame, and the first flange 203 is located on the inner side of the front panel 600. The second flange 204 is used to abut against the door liner 101 located on the rear side of the door frame. The dimension of the first flange 203 along the first direction is larger than the dimension of the second flange 204 along the first direction.

[0048] In order to set the overlapping surface 201 of the door liner 100 opposite the second flange 204 as an inclined surface, the present invention adopts, but is not limited to, the following scheme.

[0049] In one embodiment, the second flange 204 is inclined along its height to form the door liner overlap surface 201. That is, from the bottom to the top of the second flange 204, the distance between the second flange 204 and the first flange 203 gradually increases or decreases, thereby forming the inclined door liner overlap surface 201. In this case, the thickness of the second flange 204 can remain constant.

[0050] In another embodiment, the thickness of the second flange 204 gradually changes along its height to form the door liner overlap surface 201. That is, from the bottom to the top of the second flange 204, the thickness of the second flange 204 gradually increases or decreases, and the side of the second flange 204 facing the door liner 100 extends to the side of the second flange 204 away from the door liner 100 to form the door liner overlap surface 201.

[0051] The cross-sectional shape of the second flange 204 can be a triangle or a trapezoid, preferably a right triangle or a right trapezoid, with the hypotenuse of the right triangle or right trapezoid facing the door liner 100 and the right-angled side of the right triangle or right trapezoid away from the door liner 100.

[0052] Of course, the two implementation methods described above can also be used simultaneously. That is, while the thickness of the second flange 204 gradually changes, the second flange 204 is tilted so that the tilt angles of the two are superimposed, thereby reducing the thickness change rate and tilt angle of the second flange 204 at the same time.

[0053] The first flange 203 has screw holes at both its top and bottom, which are used to fix it to the handle 300 and the second trim strip 400, respectively. A bend is provided at the connection point between the first flange 203 and the side plate 202, which is used to strengthen the structural strength of the first flange 203.

[0054] Furthermore, the side plate 202 also includes a limiting plate 205 connected between the side plate 202 and the second flange 204, and a step portion 206 is formed between the second flange 204 and the limiting plate 205.

[0055] The limiting plate 205 is connected between the side plate 202 and the second flange 204. The limiting plate 205 is perpendicular to the side plate 202. The dimension of the limiting plate 205 along the height direction is the same as the dimension of the second flange 204 along the height direction. Since the side of the second flange 204 opposite to the door liner 100 (i.e., the door liner overlap surface 201) is a slope, the side of the second flange 204 opposite to the door liner 100 is misaligned with the side of the limiting plate 205 opposite to the door liner 100 in the front-back direction. The step portion 206 is formed at the connection between the second flange 204 and the limiting plate 205.

[0056] Preferably, one end of the second flange 204 along the height direction is flush with the limiting plate 205, and the other end is located on the side of the limiting plate 205 facing the first flange 203. The following description takes the example where the bottom end of the second flange 204 is flush with the bottom end of the limiting plate 205.

[0057] When the second flange 204 is inclined, the second flange 204 is inclined towards the first flange 203 from bottom to top, that is, the door liner overlapping surface 201 extends inclined towards the first flange 203 from bottom to top. At this time, the bottom of the door liner overlapping surface 201 and the side of the limiting plate 205 opposite to the door liner 100 are flush, and the top of the door liner overlapping surface 201 and the side of the limiting plate 205 opposite to the door liner 100 are misaligned. The height of the step portion 206 gradually increases from bottom to top.

[0058] As the thickness of the second flange 204 gradually changes, the thickness of the second flange 204 gradually decreases from bottom to top. The side of the second flange 204 facing the door liner 100 extends from bottom to top toward the side of the second flange 204 away from the door liner 100 to form the door liner overlapping surface 201. At this time, the bottom of the door liner overlapping surface 201 and the side of the limiting plate 205 opposite to the door liner 100 are flush, while the top of the door liner overlapping surface 201 and the side of the limiting plate 205 opposite to the door liner 100 are misaligned. The height of the step portion 206 gradually increases from bottom to top.

[0059] The step portion 206 firstly strengthens the structural strength of the second flange 204, preventing the second flange 204 from deforming under pressure; secondly, the step portion 206 defines the installation position of the door liner 100, with the edge of the door liner 100 abutting against the step portion 206, while also preventing the first trim strip 200 from tilting, causing assembly errors in the door body; finally, the step portion 206 can hide the edge of the door liner 100, improving the aesthetics of the door body.

[0060] In this embodiment, the maximum height of the step portion 206 is 1-2 mm, meaning the maximum distance between the door liner overlapping surface 201 and the opposite side of the limiting plate 205 and the door liner 100 in the front-to-back direction is 1-2 mm. If the maximum height of the step portion 206 is too small, there cannot be a significant gap difference between the door and the refrigerator body when the door is closed, thus failing to effectively reduce the opening force; if the maximum height of the step portion 206 is too large, the gap between the door and the refrigerator body when the door is closed will be too large, affecting the sealing effect.

[0061] The handle 300 is located at the top or bottom of the door liner 100 and is used to open the door. The handle 300 includes a handle body 301 and a grip portion 302, and a gripping space is formed between the handle body 301 and the grip portion 302.

[0062] The handle body 301 includes a top plate, a vertical plate extending downward from one side of the top plate, and a bottom plate extending away from the top plate from the side of the vertical plate away from the top plate. The bottom plate and the top plate are parallel. The grip portion 302 is connected to the side of the bottom plate away from the vertical plate, and the grip portion 302 extends vertically upward and is parallel to the vertical plate.

[0063] The handle 300 further includes connectors 303 located on both sides of the handle body 301 along a first direction. The connectors 303 are used to connect the handle body 301 and the grip portion 302. The connectors 303 have a first connecting portion connected to the handle body 301 and a second connecting portion connected to the grip portion 302. The first connecting portion and the second connecting portion are provided with screw holes to connect the handle body 301 and the grip portion 302. The second connecting portion is also used to connect the first trim strip 200. The second connecting portion is provided with screw holes that are compatible with the screw holes provided on the first flange 203.

[0064] It should be noted that the door liner overlapping surface 201 extends obliquely towards the handle 300 along the height direction. That is, the door liner 100, which is in contact with the door liner overlapping surface 201, is obliquely arranged towards the handle 300 along the height direction. This results in a larger gap between the door body on the side of the handle 300 and the refrigerator body, and a smaller gap between the door body on the side of the second trim strip 400 and the refrigerator body. Therefore, when opening the door through the handle 300, it can be ensured that the side of the door with the smaller gap from the refrigerator body is opened first, thereby effectively reducing the opening force.

[0065] The second trim strip 400 is disposed on the side of the door liner 100 opposite to the handle 300, and the second trim strip 400 is connected to the first trim strip 200.

[0066] In this embodiment, the handle 300 is located at the top of the door liner 100, and the second decorative strip 400 is located at the bottom of the door liner 100. The two sets of first decorative strips 200, the handle 300, and the second decorative strip 400 together form a door frame. The top end of the first decorative strip 200 is fixedly connected to the connector 303 of the handle 300 by screws, and the bottom end of the first decorative strip 200 is fixedly connected to the second decorative strip 400 by screws. The overlapping surface 201 of the door liner extends obliquely from bottom to top toward the handle 300.

[0067] Furthermore, the door also includes slide rails 500 fixed to both sides of the door liner 100 along the first direction. The slide rails 500 are used to connect with the refrigerator body, thereby sliding the door body into the refrigerator body. The slide rails 500 are located on the side of the door liner 100 near the handle 300, thereby facilitating the opening of the door.

[0068] The inclined door liner overlapping surface 201 gives the door liner 100 a certain tilt angle, resulting in a gap difference between the door and the refrigerator body when the door is closed. This creates a difference in suction between the door and the refrigerator body. The suction difference caused by the gap makes the door act as a lever. When opening the door, the handle 300 is used as the point of force application, and the lower side of the door is used as the fulcrum, which can further reduce the opening force so that the upper part of the door can be opened first.

[0069] Compared to traditional negative pressure release solutions, which require time (at least a minute between closing and reopening the door), and require significant force to open immediately after closing the freezer door, assisted opening requires mechanical handles and other components, increasing costs and potentially damaging the appearance over time due to the mechanical structure pressing against the U-shell or center beam. This invention eliminates the need for a manual handle, avoids adding a ventilation and negative pressure release structure, and minimizes manufacturing costs. Furthermore, it reduces the opening force of the large freezer door without compromising aesthetics, thus improving the user's opening experience.

[0070] In summary, the present invention limits the inclination angle of the door liner 100 by the inclination angle of the overlapping surface 201 of the door liner, thereby creating a gap difference between the door liner 100 and the refrigerator body when the door is closed. This results in a difference in door sealing suction between the door liner 100 and the refrigerator body. Thus, when the door is opened, the upper or lower side of the door (the side with the larger gap from the refrigerator body) can open first, allowing external air to enter the refrigerator body to balance the internal and external pressure, thereby reducing the opening force when opening the lower or upper side of the door (the side with the smaller gap from the refrigerator body). At the same time, the door body is sealed and attracted to the refrigerator body on all four sides by the door seal strip 101. Not opening the upper and lower sides of the door body at the same time can disperse the door sealing suction to achieve the effect of reducing the opening force, which can be reduced to 40N.

[0071] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0072] The detailed descriptions listed above are merely specific illustrations of feasible embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
