Description

Technical Field

[0001] The invention relates to the technical field of refrigerator components, and in particular to an assembling method of a refrigerator heat-insulating back plate and a refrigerator back plate heat-insulating component. Background Art

[0002] A refrigerator generally includes a refrigerator body, a refrigerator door and a refrigeration system. The refrigerator body includes a refrigerator body, a side panel and a back panel. The refrigeration system is usually arranged in the refrigerator body. In order to ensure the refrigeration effect of the refrigeration system and reduce the leakage of cold air, a foaming agent is filled between the refrigerator body and the back panel to form an insulation layer. To fill the foaming agent, the back of the refrigerator body is recessed to form a chamber, and a plurality of holes are opened in the chamber. In order to prevent the foaming agent from overflowing through the holes, the holes need to be sealed before filling the foaming agent. In the prior art, the holes are sealed by tape.

[0003] In actual application, the applicant found that the insulation layer and the cavity on the back of the refrigerator body could not be tightly connected, which affected the insulation performance. The reason was that the back of the conventional tape was smooth, and the material used for insulation was usually a foaming agent. The foaming agent could not bond to the back of the tape, and the holes in the cavity were relatively scattered, causing the tape that closed the holes to be scattered, resulting in the cavity being unable to be firmly connected to the insulation layer, affecting the insulation. Summary of the invention

[0004] One of the purposes of the present invention is to provide an assembly method for a refrigerator insulation back panel to solve the technical problem in the prior art that the insulation layer cannot be firmly connected to the back chamber of the refrigerator body due to the closed holes, thereby affecting the thermal insulation performance.

[0005] The present invention provides a basic solution 1: a method for assembling a refrigerator heat insulation back plate, comprising the following contents:

[0006] Sealing step: the back of the refrigerator body to be filled has a cavity, the bottom of the cavity has a plurality of holes, the holes are sealed by a sealing tape, the sealing tape is bonded to the bottom of the cavity, and the side of the sealing tape away from the closed holes has a plurality of capillaries;

[0007] Filling step: filling the chamber with a heat insulating material, wherein the heat insulating material is bonded to the side of the sealing tape, the bottom and the side wall of the chamber;

[0008] Covering steps: install the refrigerator back cover on the mouth of the chamber, the refrigerator back cover closes the chamber, and the insulation material is bonded to the refrigerator back cover.

[0009] Furthermore, it also includes:

[0010] Pretreatment step: coating one side of the sealing tape with glue, the coated side being used to bond the chamber to close the holes; roughening the other side of the sealing tape, the roughened side having a plurality of capillaries.

[0011] Furthermore, the preprocessing step also includes the following:

[0012] The roughened side of the sealing tape is coated with isolation oil, and the isolation oil fills the capillaries; the sealing tape coated with the isolation oil is wound into a roll.

[0013] Furthermore, the isolation oil is silicone oil.

[0014] Furthermore, the heat insulating material is foam glue, which is used to bond the bottom, side walls and rear cover of the chamber, and the foam glue is used to bond the sealing tape.

[0015] Beneficial effects of basic solution 1:

[0016] The sealing step is set up, and the holes on the chamber are sealed with a specially treated sealing tape. The side of the sealing tape away from the sealed holes has a number of capillaries, and the roughness of the back of the sealing tape is increased through the capillaries, which is convenient for subsequent bonding with the thermal insulation material. The filling step is set up, and the thermal insulation material is filled with the back of the sealing tape. Due to the presence of capillaries, the roughness of the back of the sealing tape is increased, thereby increasing the bonding stability of the thermal insulation material and the back of the sealing tape, so that the thermal insulation material and the sealing tape are firmly connected. The buckle cover step is set up, and the chamber is sealed with the back cover of the refrigerator, and at the same time, it is bonded with the thermal insulation material, so that the back cover of the refrigerator, the thermal insulation material, the sealing tape, and the chamber are an integral structure, which improves the structural integrity of the back of the refrigerator. In the application process, the order of the filling step and the buckle cover step can be interchanged. The chamber can be filled with thermal insulation material after the back cover of the refrigerator closes the chamber. The technicians in the field determine it according to the actual structure of the refrigerator.

[0017] The pretreatment step is to roughen the back of the sealing tape. The roughening treatment can effectively increase the roughness of the back of the sealing tape, thereby increasing the bonding stability between the sealing tape and the thermal insulation material (i.e., foam rubber) and improving the thermal insulation of the thermal insulation material. The roughened sealing tape needs to be stored, so the sealing tape is wound into a roll. First, the storage area of ​​the sealing tape is reduced, which is easy to store and transport. Second, the rolled sealing tape can be stretched, cut and pasted by a machine to achieve automated operation, improve production efficiency and reduce labor costs.

[0018] The sealing tape is coated with isolation oil, and the isolation oil fills the capillaries. When winding into a roll, the side of the sealing tape after being coated with glue and the side after being roughened are separated. The tape is rolled up by the winding force. When used, the sealing tape can be separated and can be bonded to the chamber. When filling the isolation material, the isolation material is foam glue, which can decompose the isolation oil. After decomposition, the foam glue contacts the capillaries, thereby realizing a stable connection between the foam glue and the sealing tape.

[0019] The adoption of this solution can solve the technical problem in the prior art that the insulation layer cannot be firmly connected to the back cavity of the refrigerator body due to the closed holes, thereby affecting the thermal insulation performance.

[0020] A second object of the present invention is to provide a refrigerator back plate insulation assembly.

[0021] The present invention provides basic solution 2: a refrigerator back plate insulation component, which is applied to the assembly method of the above-mentioned refrigerator insulation back plate.

[0022] Furthermore, it includes a sealing belt and a heat insulating member arranged in a refrigerator body, a cavity is opened at the back of the refrigerator body, and a plurality of holes are opened at the bottom of the cavity;

[0023] The sealing tape is bonded to the bottom of the chamber, and the sealing tape is used to seal the hole at the bottom of the chamber;

[0024] The heat insulation is bonded to the sealing tape, the chamber bottom, and the chamber sidewall;

[0025] The refrigerator also includes a refrigerator back cover for sealing the chamber. The refrigerator back cover is bonded to a side of the heat insulating member away from the sealing belt, and the refrigerator back cover is detachably connected to the back of the refrigerator body.

[0026] Furthermore, a plurality of capillary holes are formed on the side of the sealing belt away from the closed hole, and the heat insulating member is in contact with the capillary holes.

[0027] Furthermore, the material of the heat insulation element is foamed rubber.

[0028] Beneficial effects of basic solution 2:

[0029] The setting of the heat insulation piece is used to reduce the leakage of cold air and improve the heat preservation. The setting of the capillary pores can effectively increase the roughness of the back of the sealing belt. The heat insulation piece is bonded to the capillary pores, which effectively improves the bonding stability between the heat insulation piece and the back cavity of the refrigerator body, thereby improving the connection stability of the heat insulation piece and the heat preservation of the heat insulation piece.

[0034] Example

[0035] A method for assembling a refrigerator heat insulation back plate, as shown in the following Figure 1 As shown, including the following:

[0036] Pretreatment step: glue is applied to one side of the sealing tape 3, and the glue-coated side is used to bond the cavity closed hole 2; the other side of the sealing tape 3 is roughened, and the roughened side has a plurality of capillaries. Separation oil is applied to the roughened side of the sealing tape 3, and the separation oil fills the capillaries, and the sealing tape 3 coated with the separation oil is wound into a roll. In this embodiment, the separation oil is silicone oil.

[0037] The sealing tape 3 is coated with isolation oil so that the isolation oil fills the capillaries. When the sealing tape 3 is wound into a roll, the side of the sealing tape 3 after being coated with glue and the side of the sealing tape 3 after being roughened are separated. The sealing tape 3 is wound by the winding force, and the isolation oil is not easily transferred. When the sealing tape 3 is used, the sealing tape 3 can still be separated, and the side of the sealing tape 3 coated with glue is still sticky and can be adhered to the cavity to achieve the sealing of the hole 2.

[0038] By winding the sealing tape 3 into a roll, firstly, the storage area of ​​the sealing tape 3 is reduced, making it easy to store and transport; secondly, the rolled sealing tape 3 can be stretched, cut and pasted by a machine to achieve automated operation, improve production efficiency and reduce labor costs.

[0039] Sealing step: The back of the refrigerator body 1 to be filled has a cavity, and the bottom of the cavity has a plurality of holes 2, and the holes 2 are sealed by a sealing tape 3, the sealing tape 3 is bonded to the bottom of the cavity, and the side of the sealing tape 3 away from the closed holes 2 has a plurality of capillaries.

[0040] Filling step: fill the chamber with insulation material, the insulation material is bonded to the sides of the sealing tape 3, the bottom and side walls of the chamber. Specifically, in this embodiment, the insulation material is foam glue, the foam glue is filled in the chamber, and the foam glue is used to bond the bottom, side walls and the back cover 5 of the chamber, as well as the sealing tape 3.

[0041] When the insulating material is filled, the insulating material is foamed rubber, which can decompose the insulating oil. After decomposition, the foamed rubber contacts the capillaries, increasing the contact area between the foamed rubber and the sealing tape 3, thereby achieving a stable connection between the foamed rubber and the sealing tape 3.

[0042] Covering step: the refrigerator back cover 5 is installed at the mouth of the chamber, the refrigerator back cover 5 closes the chamber, and the heat insulation material is bonded to the refrigerator back cover 5. Specifically, the foam glue is bonded to the refrigerator back cover 5, and the refrigerator back cover 5 is detachably connected to the back of the refrigerator body 1 by screws.

[0043] During the application process, the order of the filling step and the covering step can be interchanged. After the chamber is closed by the refrigerator rear cover 5, the chamber can be filled with insulation material, which is determined by technical personnel in the field based on the actual structure of the refrigerator.

[0044] A refrigerator back plate insulation assembly is used in the assembly method of the refrigerator insulation back plate. Figure 2 As shown, it includes a sealing belt 3 and a heat insulating member 4 arranged in a refrigerator body 1, a cavity is opened at the back of the refrigerator body 1, and a plurality of holes 2 are opened at the bottom of the cavity.

[0045] The sealing tape 3 is bonded to the bottom of the chamber, and is used to seal the hole 2 at the bottom of the chamber; a plurality of capillaries are formed on the side of the sealing tape 3 away from the sealed hole 2. The capillaries are formed by the roughening treatment of the sealing tape 3, and in the initial state, the side of the sealing tape 3 with the capillaries is coated with isolation oil.

Specifically, the refrigerator back cover 5 is detachably connected to the back of the refrigerator body 1 by screws, and the heat insulating member 4 formed by foam glue is bonded to the chamber, the sealing belt 3, and the refrigerator back cover 5.

[0048] The setting of the heat insulating member 4 is used to reduce the leakage of cold air and improve the heat preservation. The setting of the capillary pores can effectively increase the roughness of the back of the sealing belt 3. The heat insulating member 4 is bonded to the capillary pores, which effectively improves the bonding stability between the heat insulating member 4 and the back chamber of the refrigerator body 1, thereby improving the connection stability of the heat insulating member 4 and the heat preservation of the heat insulating member 4.
