[0030] See also Figure 1-3, is a schematic diagram of a refrigerator 100 provided in one embodiment of the present invention. The refrigerator 100 includes a box body 10 and a door body for opening or closing the box body 10 . The box body 10 includes a shell 11 and an inner tank 12 .

[0031] Preferably, the refrigerator 100 further includes an installation box 20 disposed between the shell 11 and the inner tank 12 and a control module 30 disposed in the installation box 20. A foaming cavity is formed between the shell 11 and the inner tank 12. In this embodiment, the installation box 20 is disposed at the front side of the foaming cavity and is disposed close to the top wall of the shell 11, thereby increasing the distance between the bottom of the installation box 20 and the inner tank 12, thereby increasing the insulation thickness between the two, thereby reducing the influence of the temperature in the box on the control module 30, and the heat generated by the control module 30 when working can also be conducted away with the help of the metal shell 11, thereby enhancing the heat dissipation effect.

[0032] More specifically, Figure 6 As shown, the installation box 20 is pre-buried in the box body 10 for the control module 30 to be inserted, and the installation box 20 includes an upper box body 22 and a lower box body 23, and an assembly space 201 for accommodating the control module 30 is provided between the upper and lower box bodies 22 and 23. The upper box body 22 is arranged to cover the top wall of the shell 11, and the lower box body 23 is downwardly spaced a distance from the inner liner 12 to ensure the heat preservation effect of the installation box 20.

[0033] Preferably, the control module 30 includes a main control component 40 and a display control component 50, which are assembled into the installation box 20 after being positioned and matched. The control module 30 is integrated into the refrigerator 100, which simplifies the installation steps, saves time and effort, and can be disassembled in one piece for subsequent maintenance. The main control component 40 is used for electrical control of various electronic components of the refrigerator 100 and / or control of LEDs, display panels, etc. The display control component 50 is used for electronic control of light-emitting LEDs, display panels, etc.

[0034] Ginseng Figure 8-10 As shown, the main control component 40 includes a main control circuit board 41 and a main control board bracket 43 for supporting the main control circuit board 41. The display control component 50 includes a display control circuit board 51 and a display control board bracket 53 for supporting the display control circuit board 51.

[0035] Preferably, the main control circuit board 41 and the display control circuit board 51 are connected by a flexible flat cable, and the two circuit boards do not need to be matched through a plug connector, which optimizes the plug-in steps and makes assembly more convenient and labor-saving. Alternatively, the display control circuit board 51 and the main control circuit board 41 are integrated into one circuit board to save costs.

[0036] Specifically, the main control board bracket 43 has a first bottom wall 431, a first end wall 432 and a first rear wall 433. The first bottom wall 431, the first end wall 432 and the first rear wall 433 are arranged to form a receiving space 430. The main control circuit board 41 is installed in the receiving space 430. The main control board bracket 43 also separates another installation space 4301 adjacent to the first end wall 432.

[0037] Preferably, the refrigerator 100 includes a wireless communication module 60 disposed on the main control board bracket 43, and the wireless communication module 60 is separately disposed on one side of the main control circuit board 41 and the display control circuit board 51 in the horizontal direction. Specifically, the wireless communication module 60 is installed in another installation space 4301, and the wireless communication module 60 does not overlap with the main control circuit board 41 and the display control circuit board 51 in the horizontal direction, and the main control circuit board 41 and the display control circuit board 51 do not block the wireless communication module 60 in the front-to-back direction, and do not affect communication.

[0038] Specifically, the refrigerator 100 integrates the wireless communication module 60 into the main control board bracket 43. Because the PCB circuit board will hinder the propagation of the wireless communication signal, in this case, there is no circuit board set in the front area of ​​the wireless communication module 60, and the front area only has a plastic structure, so that the wireless communication signal can propagate outward. In addition, after the fully embedded refrigerator is fixed to the cabinet, it is difficult to drag it out as a whole. It is necessary to remove a series of mounting parts before the refrigerator can be dragged out. The refrigerator of the prior art places the wireless communication module 60 on the top. Once damaged, the entire refrigerator needs to be dragged out before it can be repaired. The present invention integrates the wireless communication module 60 in the main control board bracket 43. Once damaged, the refrigerator can also be repaired and replaced in the cabinet, making after-sales maintenance more convenient and quick, saving time and effort.

[0039] Preferably, the display and control board bracket 53 is open to the rear, and the display and control board bracket 53 includes a second front wall 531, a second end wall 532, a second top wall 533 and a second bottom wall 534; the second front wall 531, the second end wall 532, the second top wall 533 and the second bottom wall 534 are arranged to form an installation space 530 that is open to the rear. The display and control assembly 50 includes a display color film 54 and a display mask 55 disposed on the second front wall 531, and the flexible flat cable is reserved for a certain length, so that the display and control circuit board 51 can be stretched a certain distance and installed parallel to the display and control board bracket 53 from the back to the front.

[0040] Combination Figure 11-12As shown, the main control circuit board 41 and the display control circuit board 51 are connected by a flexible flat cable, and the main control circuit board 41 is first installed on the main control board bracket 43, and then the display control circuit board is stretched forward for a distance and installed in the installation space 530. The second front wall 531 extends into the installation space 530 with a plurality of positioning posts 5311, and the display control circuit board 51 is correspondingly provided with a plurality of positioning grooves that cooperate with the positioning posts. The second top wall 533 and the second bottom wall 534 extend into the installation space 530 with a plurality of positioning protrusions 5331, and the positioning protrusions 5331 clamp the upper edge and the lower edge of the display control circuit board 51. In this way, the display control circuit board 51 and the display control board bracket 53 are more stably combined.

[0041] Preferably, the second front wall 531 is provided with a groove 5312 for accommodating the display color film, the display color film 54 does not protrude from the second front wall 531, and the display mask 55 is snapped onto the display control board bracket 53 and completely covers the display control board bracket 53; the display color film 54 is provided with a light-transmitting character area, and the light-transmitting area provided by the display mask 55 covers the character area, so that the characters can be displayed through the display mask 55.

[0042] Specifically, refer to Figure 11-12 The display mask 55 is an in-mold injection molded part, which is transparent as a whole and coated on the front. The position where the character is displayed can be transparent to form a transparent area, and the rest of the position is not transparent. The display color film 54 is applied to the groove 5312 corresponding to the display control board bracket 53. The characters are generally set as the transparent area, and the rest are not transparent. The display mask 55 and the display control board bracket 53 are snapped together and assembled. The transparent area of ​​the display mask 55 just covers the character position of the display color film 54. When the light is on, the display characters will be lit synchronously. Of course, if the refrigerator selects a different mode, different characters will be lit.

[0043] Preferably, the display and control component 50 further includes a magnetic switch 57 and / or an ambient temperature sensor 56 installed in front of the display and control circuit board 53 .

[0044] Specifically, the magnetic switch 57 and / or the ambient temperature sensor 56 are arranged near the second end wall 532 to facilitate wiring. The magnetic switch 57 is snapped into the corresponding slot of the display and control board bracket 53. The magnetic switch 57 is mainly used to control the operation and shutdown of the internal electrical components of the refrigerator 100 after the refrigerator 100 door is opened and closed. The ambient humidity sensor 56 can also be integrated into the display and control board bracket 53, eliminating the cost of opening a separate installation embedded box for the humidity sensor 56 on the top of the box body. At the same time, the fully embedded refrigerators on the market currently do not use this ambient humidity sensor 56. The design of the present invention has an additional function compared to the fully embedded refrigerator. The ambient humidity sensor 56 is also pre-installed into the corresponding card slot of the display and control board bracket 53. The ambient humidity sensor 56 is mainly used to sense the changes in humidity and temperature outside the refrigerator 100 to better control the operation of the refrigerator 100.

[0045] The assembly method of the control module 30 of the present invention is as follows: the display color film 54 is pasted in the groove 5312 of the display control board bracket 53, the display mask 55 covers the display color film 54 and is buckled in front of the display control board bracket 53; the magnetic switch 57 and / or the ambient temperature sensor 56 are assembled into the display control board bracket 53 from back to front; the main control circuit board 41 and the display control circuit board 51 connected as one by a flexible flat cable are prepared, the main control circuit board 41 and the display control circuit board 51 are perpendicular to each other, and the main circuit board 41 is horizontally supported on The main control board bracket 43 and the display and control circuit board 51 are vertically positioned in the receiving space 430; the wireless communication module 60 is installed in another receiving space; the display and control circuit board 51 is stretched forward to fix it on the display and control board bracket 53; the cables of the magnetic switch 57 and / or the cables of the ambient humidity sensor 56 are arranged so that the cables can pass through the gap at the second end wall 532 and be pulled into the main control board bracket 43 to facilitate the subsequent connection of the cables during the assembly of the refrigerator 100; finally, the display and control board bracket 53 and the main control board bracket 43 are snapped together.

[0046] In this way, the control module 30 is assembled and supplied to the factory division as a component assembly. When it is installed on the refrigerator, it only needs to be connected to the cables and pushed into the installation box 20, and then fixed by the relevant buckles. Compared with the conventional solution, it saves operation steps, time and labor. Similarly, when disassembly is required, the control module 30 can be disassembled as a whole at the same time for easy maintenance. Figure 7-9 As shown, the clamping connection between the display and control board bracket 53 and the main control board bracket 43, and the clamping connection between the display and control board bracket 53 and the installation box 20 will be described in detail.

[0047] Preferably, the second end wall 532 of the display and control board bracket 53 is provided with a snap groove 5321, and the end of the main control board bracket 43 is provided with a first elastic arm 4321 corresponding to the snap groove 5321, and the first elastic arm 4321 is locked with the snap groove 5321 to prevent the display and control board bracket 53 from detaching backwards. The front end edge of the first end wall 432 is bent backwards to form the first elastic arm 4321, and there is a clearance space between the first elastic arm 4321 and the first end wall 432 for the first elastic arm 4321 to deform and make way.

[0048] Preferably, the first elastic arm 4321 abuts against the installation box 20 backwards, and when the control module 30 is assembled into the installation box 20, the control module 30 is prevented from being excessively installed backwards; the first elastic arm 4321 is provided with a guide block 4322 and a fixed block 4323, the guide block 4322 guides and abuts against the second end wall 532 of the display and control board bracket, and the fixed block 4323 abuts against the inner wall surface of the buckle groove 5321 to limit the position. The guide block 4322 is located in front of the fixed block 4323, and when the display and control board bracket 53 is buckled with the main control board bracket 43, the second end wall 532 abuts against the guide block 4322, so that the second end wall 532 deforms inwards to give way, and finally passes through the fixed block 4323, and the fixed block 4323 abuts against the inner wall surface of the buckle groove 5321 backwards, preventing the display and control board bracket 53 from loosening the main control board bracket 43.

[0049] Preferably, the first end wall 432 of the main control board bracket is further provided with an abutting arm 4320, and the abutting arm abuts the installation box 20 in the transverse direction. Specifically, the inner wall of the installation box 20 is provided with a convex bump 202, and after the main control board bracket 43 is assembled into the installation box 20, the abutting arm 4320 abuts against the convex bump 202, which is conducive to the transverse limitation of the main control board bracket 43 in the installation box 20.

[0050] Preferably, the second end wall 532 of the display and control board bracket 53 is provided with a second elastic arm 5322, and the second elastic arm 5322 is vertically arranged in parallel with the snap groove 5321; the second elastic arm 5322 has a step portion 5323 protruding toward the installation box 20; the installation box 20 is provided with a clamping portion 21 cooperating with the step portion 5323.

[0051] Specifically, the control module 30 is an integrated assembly, and the main control board bracket 43 cooperates with the display control board bracket 53 through the first elastic arm 4321, and cooperates with the installation box 20 through the abutment arm. The display control board bracket 53 cooperates with the installation box 20 through the second elastic arm 5322. Specifically, the clamping portion 21 abuts against the step portion 5323 backwards. The setting of the step portion 5323 prevents the clamping portion 21 from sliding over easily, thereby ensuring the stability of the positioning of the display control board bracket 53 and the installation box 20.

[0052] Specifically, combined Figure 4-5As shown, the display mask 55 is removed for observation. In actual operation, the display mask 55 is snap-connected with the display and control board bracket 53 and will not be removed separately first. In actual operation, the display mask 55 has a receiving groove 550 on the bottom surface of the second end wall 532 of the display and control board bracket 53 for a tool (such as a screwdriver) to enter. The screwdriver can be inserted and the screwdriver head can be used to move the second elastic arm 5322 so that the second elastic arm 5322 is deformed inwardly, and the holding portion 21 can gradually slide over the step portion 5323. The holding portion 21 is loosened from the step portion 5323, and the display and control board bracket 53 and the installation box 20 are released from the limit. At this time, the display mask 55 is pulled, and the display and control component 50 and the main control component 40 can be removed from the installation box 20, which is convenient for subsequent maintenance work. Obviously, by operating the screwdriver to move the second elastic arm 5322, the control module 30 can be disassembled as a whole, which is convenient for subsequent maintenance.

[0053] The beneficial effects of the present invention are as follows: after the display and control component 50 and the main control component 40 are assembled, they are installed into the installation box 20 together, which optimizes the plug-in steps and saves effort and time; the second elastic arm 5322 can be moved by a screwdriver, and the second elastic arm 5322 can solve the limit together with the installation box 20, and the display and control component 50 and the main control component 40 can be disassembled from the installation box 20 together, which is convenient for subsequent maintenance; the main control circuit board 41 and the display and control circuit board 51 are connected by a soft flat cable, without the need for plug-in terminals, and are convenient for assembly; the main control board bracket 43 is provided with a wireless communication module 60 on one side of the main control circuit board 41 and the display and control circuit board 51, which does not affect the wireless signal propagation of the wireless communication module 60; the display and control board bracket is integrated with a magnetic sensitive switch 57 and / or an ambient temperature sensor 56, has more functions, and improves customer experience.
