DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0033] like Figures 1 to 8 As shown, the refrigerator bottom plate assembly provided by the utility model includes a bottom steel 100 and a lower beam 200. The bottom steel 100 and the lower beam 200 are matched with each other, and a sealing sponge is applied at the matching position to fill and seal the gap between the bottom steel 100 and the lower beam 200, so as to prevent overflow during the foaming process of the refrigerator.

[0034] Among them, an insertion part 101 is provided on the front edge of the bottom steel 100, and the insertion part 101 is used to cooperate with the lower beam 200. The insertion part 101 is inserted into the sealing area of ​​the lower beam 200, and cooperates with the sealing sponge to fill and seal the sealing area, so as to realize the sealed connection between the bottom steel 100 and the lower beam 200, and prevent the foaming material from overflowing from the assembly gap between the bottom steel 100 and the lower beam 200 during the foaming process of the refrigerator.

[0035] Furthermore, the insertion portion 101 includes an arc-shaped portion extending upward from the front edge of the bottom steel 100 and a horizontal portion extending horizontally forward from the arc-shaped portion, the horizontal portion is used to cooperate and seal with the lower beam 200, the bottom of the horizontal portion is in contact with the lower beam 200, and a step portion is formed at the connection between the arc-shaped portion and the horizontal portion. On the one hand, the step portion can increase the structural strength of the front side of the bottom steel 100 and enhance the stability and firmness of the cooperation between the horizontal portion and the lower beam 200. On the other hand, the step portion can play a limiting role. The rear edge of the lower beam 200 abuts against the step portion to limit the insertion depth of the insertion portion 101, and at the same time can maintain the consistency of the assembly depth of the bottom steel 100 and the lower beam 200, thereby preventing the bottom steel 100 from tilting and affecting the assembly size of the refrigerator.

[0036] In this embodiment, the height of the arc portion is 1 mm-1.4 mm, preferably 1.2 mm, which may be determined according to the thickness of the lower beam 200 to ensure the flatness of the bottom of the refrigerator after the bottom steel 100 and the lower beam 200 are assembled.

[0037] The lower beam 200 includes a lower beam bottom plate 201 and a lower beam vertical plate 206. The lower beam vertical plate 206 and the lower beam bottom plate 201 are perpendicular to each other and are L-shaped to form the main structure of the lower beam 200. The lower beam 200 also includes a sealing plate 202 located on the top of the lower beam bottom plate 201. A first sealing area 203 is formed between the lower beam bottom plate 201 and the sealing plate 202. The insertion portion 101 is inserted into the first sealing area 203.

[0038] Specifically, the horizontal portion of the insertion portion 101 is inserted into the first sealing area 203, the horizontal portion is fitted with the lower beam bottom plate 201, the rear edge of the lower beam bottom plate 201 is abutted against the step portion, and a sealing sponge is applied between the horizontal portion and the sealing plate 202, thereby sealing the first sealing area 203. The sealing sponge can be pre-installed on the top of the horizontal portion in advance, so that when the horizontal portion is inserted into the first sealing area 203, the sealing sponge simultaneously fills and seals the first sealing area 203 and maintains the close contact between the horizontal portion and the lower beam bottom plate 201.

[0039] In this way, a double-layer seal can be formed in the first sealing area 203, the first layer of seal is the sealing sponge between the horizontal part and the sealing plate 202, and the second layer of seal is the horizontal part and the lower beam bottom plate 201 that are tightly fitted to each other under the compression of the sealing sponge, thereby effectively preventing overflow during the foaming process without applying aluminum foil tape; and by inserting the horizontal part into the second sealing area 203, the top and bottom surfaces of the horizontal part are limited at the same time, and the sealing sponge is confined in the first sealing area 203, so that there is no need to clamp with the help of a foaming clamp, and the bottom steel 100 and the lower beam 200 will not separate during the foaming process.

[0040] Furthermore, the sealing plate 202 includes a first extension portion 202a extending upward from the middle of the lower beam bottom plate 201, and a second extension portion 202b extending backward from a side edge of the first extension portion 202a away from the lower beam bottom plate 201, the first extension portion 202a is perpendicular to the lower beam bottom plate 201, and the first sealing area 203 is formed between the second extension portion 202b and the lower beam bottom plate 201.

[0041] Furthermore, the sealing plate 202 further includes a third extension portion 202c extending backward from the side edge of the second extension portion 202b away from the first extension portion 202a, and the third extension portion 202c extends obliquely upward. The opening of the third extension portion 202c gradually increases in the direction away from the second extension portion 202b, so as to guide the horizontal portion to be inserted into the first sealing area 203 during the assembly process, and the horizontal portion gradually enters the second sealing area 203 along the inclined surface of the third extension portion 202c. The large opening between the third extension portion 202c and the bottom plate 201 of the lower beam facilitates the alignment of the bottom steel 100 and the lower beam 200, thereby accelerating the assembly rate of the bottom steel 100 and the lower beam 200.

[0042] Preferably, the second extension portion 202b also extends upwardly at an angle, and the inclination angle of the third extension portion 202c is greater than the inclination angle of the second extension portion 202b. The third extension portion 202c is arranged to be inclined to guide the insertion of the bottom steel 100, and the second extension portion 202b is arranged to be inclined to squeeze the sealing sponge on the horizontal portion, so that the sealing sponge completely seals the first sealing area 203.

[0043] The sealing sponge is pre-applied to the top of the horizontal part. When the bottom steel 100 and the lower beam 200 are assembled, the lower beam 200 is moved toward the bottom steel 100. The insertion portion 101 at the front edge of the bottom steel 100 enters the first sealing area 203 from the opening between the third extension portion 202c and the bottom plate 201 of the lower beam. The insertion portion 101 gradually moves toward the second extension portion 202b under the guidance of the third extension portion 202c. When moving to the second extension portion 202b, the sealing sponge is squeezed by the second extension portion 202b. As the insertion portion 101 goes deeper, the sealing sponge is gradually compressed and the insertion portion 101 fits tightly with the bottom plate 201 of the lower beam, thereby completely sealing the first sealing area 203.

[0044] In this embodiment, the distance between the second extension portion 202b and the bottom plate 201 of the lower beam is 2-6 mm, and the distance between the third extension portion 202c and the bottom plate 201 of the lower beam is 6-17 mm.

[0045] The sealing plate 202 further includes a connecting portion 202d extending horizontally forward from a side edge of the first extension portion 202a away from the second extension portion 202b, and the connecting plate 202d is connected to the lower beam bottom plate 201. The connecting portion 202d is used to fix the sealing plate 202 to the top of the lower beam bottom plate 201, and the connecting portion 202d is parallel to the lower beam bottom plate 201, thereby increasing the contact area between the connecting portion 202d and the lower beam bottom plate 201, and increasing the firmness of the connection between the sealing plate 202 and the lower beam bottom plate 201.

[0046] It should be particularly noted that, due to the limitation of the step portion provided on the insertion portion 201, there is a certain distance between the end of the horizontal portion of the insertion portion 201 and the connection position between the first extension portion 202a and the connecting portion 202d, thereby preventing the horizontal portion from being inserted too deeply and damaging the connection between the connecting portion 202d and the lower beam bottom plate 201, or causing deformation of the insertion portion 201.

[0047] Furthermore, the lower beam 200 also includes reinforcing irons 204 located on both sides of the lower beam bottom plate 201 along a first direction, the first direction being the left and right direction of the refrigerator, the bottom of the reinforcing irons 204 having a first plane 204a and a second plane 204b higher than the first plane 204a, the second plane 204b being located in front of the first plane 204a, a second sealing area 205 being formed between the second plane 204b and the lower beam bottom plate 201, and the insertion portion 101 being inserted into the second sealing area 205.

[0048] The sealing plate 202 is located between the two groups of reinforcing irons 204, and the reinforcing irons 204 are also L-shaped to connect with the lower beam bottom plate 201 and the lower beam vertical plate 206. The first plane 204a at the bottom of the reinforcing iron 204 is used to connect with the lower beam bottom plate 201, and a gap is formed between the second plane 204b higher than the first plane 204a and the lower beam bottom plate 201 to form the second sealing area 205. The inserting part 101 is inserted into the first sealing area 203 and the second sealing area 205 at the same time, and the sealing sponge pre-installed on the horizontal part fills and seals the second sealing area 205 at the same time. The second plane 204b can be formed by stamping or injection molding.

[0049] When the horizontal part is inserted into the second sealing area 205, the sealing sponge simultaneously fills and seals the second sealing area 205 and maintains the close contact between the horizontal part and the lower beam bottom plate 201. In this way, a double-layer seal is formed in the second sealing area 205, the first layer of seal is the sealing sponge between the horizontal part and the second plane 204b, and the second layer of seal is the horizontal part and the lower beam bottom plate 201 that are closely attached to each other under the pressure of the sealing sponge, so that overflow can be effectively prevented during the foaming process without applying aluminum foil tape.

[0050] In this embodiment, the distance between the second plane 204 b and the bottom plate 201 of the lower beam is 2-3 mm, which is consistent with the minimum distance between the second extension portion 202 b and the bottom plate 201 of the lower beam.

[0051] The reinforcing iron 204 also includes a guide portion 204c located at the rear edge thereof, and the guide portion 204c extends upwardly and obliquely in a direction away from the second plane 204b. The opening of the guide portion 204c gradually increases in a direction away from the second plane 204b, which can guide the insertion portion 101 to be inserted into the second sealing area 205 on the one hand, and can squeeze the sealing sponge on the horizontal portion during the guiding process to completely seal the second sealing area on the other hand. The inclination angle of the guide portion 204c is the same as the inclination angle of the second extension portion 202b.

[0052] The bottom steel 100 is assembled onto the lower beam 200, and the lower beam 200 is moved toward the bottom steel 100. Under the guidance of the third extension portion 202c, the insertion portion 101 at the front edge of the bottom steel 100 is inserted into the first sealing area 203 between the second extension portion 202b and the bottom plate 201 of the lower beam, and inserted into the second sealing area 205 between the second plane 203b and the bottom plate 201 of the lower beam. The sealing sponge preset at the top of the horizontal portion is squeezed by the second extension portion 202b and the guide portion 204c to completely seal the first sealing area 203 and the second sealing area 205. The water The bottom of the flat portion fits tightly with the bottom plate 201 of the lower beam, thereby forming a double-layer seal at the top and bottom surfaces of the horizontal portion. Without the need for external aluminum foil tape, it is possible to effectively prevent overflow during the foaming process, saving manpower and material resources. By inserting the insertion portion 101 of the bottom steel 100 into the first sealing area 203 and the second sealing area 205, under the action of the second extension portion 202b and the second plane 204b, there is no need to rely on the foaming clamp to clamp, the sealing sponge can achieve the sealing purpose under extrusion, and there is no need to worry about the bottom steel 100 and the lower beam 200 being separated from each other up and down due to the pressure of foaming during the subsequent foaming process.

[0053] The utility model also provides a refrigerator, which includes the above-mentioned refrigerator bottom plate assembly. The above-mentioned sealing scheme is adopted to ensure that the bottom of the refrigerator body is clean and flat during the foaming process and after the foaming, and there is no overflow at the bottom of the body; and the process of sticking a sealing aluminum foil tape on the bottom of the refrigerator is omitted, thereby reducing the manufacturing cost of the refrigerator and speeding up the operation process of the refrigerator.

[0054] In summary, the utility model arranges the sealing plate 202 on the top of the lower beam bottom plate 201 to form a first sealing area 203 between the lower beam bottom plate 201 and the sealing plate 202, and inserts the insertion portion 101 of the bottom steel 100 into the first sealing area 203, and fills the sealing sponge between the insertion portion 101 and the sealing plate 202 to achieve double sealing of the first sealing area 203 without external aluminum foil tape; and the sealing purpose can be achieved by extruding the sealing plate 202 without the aid of a foaming clamp.
