Referring to fig. 4 to 5, fig. 4 is an exploded view of an embodiment of an electronic control box provided in the present application; fig. 5 is an exploded view of the electronic control box of fig. 4 from another perspective. The cover 20 includes a first opening 20a and a top cover 21 disposed opposite to each other, and in addition, the cover 20 further includes a side cover 22 surrounding a periphery of the top cover 21, wherein the top cover 21 is a top wall of the electronic control box 100, and the side cover 22 is a portion of a side wall of the electronic control box 100.

The electric control box 100 has high universality, can be produced in large scale and has low cost.

The electronic control box 100 also includes a control board 30. The control board 30 is accommodated in the accommodation chamber 100a. The control board 30 is connected to the side of the cover 20 facing the chassis 10, and the side of the control board 30 provided with the components faces the chassis 10. When the liquid flows into the accommodating cavity 100a, the liquid is not converged on the side of the control board 30 where the components are arranged based on the gravity factor, so that the control board 30 and the components on the control board 30 are prevented from being affected by the liquid to be wetted and aged, and the service life of the refrigerator 1000 is ensured.

The cover 20 and the chassis 10 are stacked in the first direction. The projection of the control board 30 in the first direction falls on the chassis 10. The cover 20 hasbase:Sub>A length H1 in the first directionbase:Sub>A-base:Sub>A. The chassis 10 hasbase:Sub>A length H2 in the first directionbase:Sub>A-base:Sub>A. The length of the control board 30 in the first directionbase:Sub>A-base:Sub>A is H0. The relationship between H1 and H2 is: h1> H2 such that the volume of the first cavity 20b is larger than the volume of the second cavity 10b. The relationship between H1 and H0 is: h1 Not less than H0/3, so that the control board 30 can be wholly or at least mostly located in the first cavity 20b, and the components of the control board 30 facing the chassis 10 side are prevented from contacting the bottom board 11, the components of the control board 30 facing the chassis 10 side are prevented from being disturbed by the liquid dropping to the bottom board 11, the control board 30 is protected, and the service life of the refrigerator 1000 is guaranteed.

The side of the top cover 21 facing the chassis 10 is provided with a plurality of mounting posts 211, and the mounting posts 211 extend from the top cover 21 toward the chassis 10 side. The mounting column 211 may be integrally formed with the top cover 21, so as to ensure structural strength of the mounting column 211 and sealability of the accommodating cavity 100a, and further ensure waterproof performance of the electronic control box 100.

The control board 30 has mounting holes 30a that mate with the mounting posts 211. The mounting posts 211 are inserted into the mounting holes 30a to connect the control board 30 with the top cover 21. The control board 30 is spaced apart from the top cover 21. The number of the mounting posts 211 of the top cover 21 corresponds to the number of the mounting holes 30a of the control board 30, so that the control board 30 and the top cover 21 can be better matched, the structural strength is improved, and a better heat dissipation effect can be achieved.

In some embodiments, the end of the mounting post 211 may be locked to the mounting hole 30a by a fixing member such that the control board 30 is spaced apart from the top cover 21, and thus, the side of the control board 30 facing the top cover 21 is not in contact with the top cover 21. The components and parts can be set up to the one side of control panel 30 towards top cap 21, and set up the length of components and parts in this side in the first direction be less than the distance between the relative surface towards each other of control panel 30 and top cap 21, avoid the components and parts of control panel 30 towards top cap 21 one side to contact top cap 21 to improve the radiating efficiency of control panel 30 and this side components and parts, guarantee the performance of control panel 30, thereby further improve refrigerator 1000's life.

Referring to fig. 6 to fig. 8, fig. 6 is a schematic perspective view of an embodiment of an electronic control box provided in the present application; fig. 7 is a schematic perspective view of another embodiment of an electronic control box provided in the present application; fig. 8 is a top view of one embodiment of an electronic control box provided herein. The side cover 22 extends from the top cover 21 toward the chassis 10 side. At least one side cover 22 has a plurality of heat dissipating ribs 221. The heat dissipating ribs 221 are located on a surface of the side cover 22 facing and/or facing away from the accommodating chamber 100a. The heat dissipation rib 221 is disposed on a surface of the side cover 22 facing the accommodating cavity 100a, and enlarges a heat absorption area of the side cover 22 to the accommodating cavity 100a. The heat dissipation rib 221 is disposed on a surface of the side cover 22 facing away from the accommodating cavity 100a, and enlarges a heat dissipation area of the side cover 22. The heat dissipation ribs 221 on the surface of the side cover 22 facing the accommodating cavity 100a are used for absorbing heat inside the accommodating cavity 100a so as to cool the control board 30, and the heat dissipation ribs 221 on the surface of the side cover 22 facing away from the accommodating cavity 100a are used for releasing the heat absorbed by the heat dissipation ribs 221 on the surface of the side cover 22 facing the accommodating cavity 100a to the external environment, so that the heat dissipation efficiency of the control board 30 is improved. The heat dissipation ribs 221 are provided to expand the heat absorption area and the heat dissipation area, so that the control board 30 achieves a rapid cooling heat dissipation effect.

In some embodiments, the heat dissipating ribs 221 may be disposed at intervals on the side cover 22, and the heat dissipating ribs 221 may be heat dissipating concave ribs. The heat dissipation ribs 221 may also serve as reinforcing ribs, thereby ensuring structural strength of the cover 20 while reducing the overall weight of the electronic control box 100. The extending direction of the heat dissipating ribs 221 may be flexibly set according to practical needs, for example, may have a transverse direction, may have a longitudinal direction, and may also have a crisscross direction.

On the premise of ensuring the waterproof performance of the electric control box 100 and ensuring that components on the control board 30 cannot contact the top cover 21, the bottom plate 11 and the side plates 12, heat dissipation ribs 221 can be arranged on one side of the top cover 21, the bottom plate 11 and the side plates 12 facing and/or facing away from the accommodating cavity 100a, so that heat dissipation in the accommodating cavity 100a is accelerated, and heat dissipation efficiency of the control board 30 is improved. Based on the above characteristics, the control board 30 is not damaged due to high heat accumulated in the accommodating chamber 100a, the safety of the control board 30 is ensured, and the service life of the control board 30 is prolonged.

Good heat dissipation effect can be achieved by arranging the heat dissipation ribs 221, so that heat dissipation holes do not need to be formed in the surface of the electric control box 100, water inflow of the electric control box 100 is prevented, and the waterproof performance and the heat dissipation performance of the electric control box 100 are considered. In addition, since the electric control box 100 has no heat dissipation holes, insects and other organisms can be prevented from entering the accommodating cavity 100a through the heat dissipation holes to damage components in the electric control box 100, so that the use safety of the electric control box 100 is improved, and faults are relieved.

In some embodiments, the end face of the side cover 22 facing away from the top cover 21 has a first flange 23. With continued reference to fig. 3, and with further reference to fig. 9, fig. 9 is a schematic perspective view of the electronic control box of fig. 3 at another view angle. The first flange 23 includes a first extension 231. The first extension 231 extends from the side cover 22 away from the accommodating chamber 100a, so that the liquid sliding from the top cover 21 or the side cover 22 flows along the first extension 231 in a direction away from the connection of the chassis 10 and the cover 20, and the liquid is relieved from penetrating into the accommodating chamber 100a. The first flange 23 further comprises a second extension 232. The second extension 232 is located at a side of the first extension 231 facing away from the side cover 22, and extends from the first extension 231 toward a side of the chassis 10. The plane of the first extension 231 may be perpendicular to the plane of the side cover 22, and the plane of the second extension 232 may be perpendicular to and parallel to the plane of the side cover 22, so that the plane of the first extension 231 may be parallel to the plane of the second extension 232.

The second extension portion 232 has a plurality of fixing portions 233. The fixing portion 233 and the second extension portion 232 may be integrally formed, thereby ensuring structural strength of the fixing portion 233. Any one of the fixing portions 233 has a fixing hole 233a, and the fixing hole 233a is used to detachably connect the chassis 10 with the cover 20.

The side plate 12 of the chassis 10 surrounds the periphery of the bottom plate 11 of the chassis 10, and the side plate 12 extends toward the cover 20 side. The chassis 10 comprises a second cuff 13. The second flange 13 is located at the end face of the side plate 12 facing away from the bottom plate 11. The second flange 13 extends from the side plate 12 away from the receiving chamber 100a. The plane of the second flange 13 may be perpendicular to the plane of the side plate 12. When the chassis 10 is detachably connected with the cover 20, the plane where the second flange 13 is located may be parallel to the plane where the first extension 231 is located, and the surface of the second flange 13 facing the side of the cover 20 may be attached to the surface of the first extension 231 facing the side of the chassis 10, so that the structure is more compact, and the structural strength is improved.

In some embodiments, a seal may be provided between the second flange 13 and the first extension 231. The shape of the sealing element can be flexibly arranged according to actual needs, for example, the shape of the sealing element can be strip-shaped or square. The seal may be selected from a sealing material made of silicone, rubber or polytetrafluoroethylene. The sealing member may have a certain elasticity, and function to seal the liquid, thereby further improving the waterproof performance of the electronic control box 100.

The second flange 13 is provided with a fixing member 14 cooperating with the fixing hole 233a on a side facing away from the cover 20. The fixing member 14 is engaged with the fixing hole 233a, and a surface of the second flange 13 facing the cover 20 is attached to a surface of the first extension 231 facing the chassis 10. The end of the fixing piece 14 on the side facing away from the side plate 12 in the second direction B-B or the third direction C-C protrudes from the end of the second flange 13 on the side facing away from the side plate 12 in the second direction B-B or the third direction C-C, and the thickness of the end of the fixing piece 14 on the side gradually increases along the direction facing the side plate 12 in the second direction B-B or the third direction C-C, so that the fixing piece 14 is conveniently clamped in the fixing hole 233a, the adaptation degree is higher, the assembly efficiency is improved, and in addition, the stability of the electronic control box 100 after connection can also be improved. The surface of the fixing member 14 on the side facing the cover 20 is lower than the surface of the second flange 13 on the side facing the cover 20, and therefore, the liquid cannot infiltrate into the accommodating chamber 100a along the surface of the second flange 13 on the side facing the cover 20 through the fixing hole 233a, thereby further improving the waterproof performance of the electronic control box 100.

After the electric control box 100 is installed, the first flange 23 of the cover body 20 is the second flange 13 with two sides wrapped up on the chassis 10, when liquid is spilled to the top cover 21 or spilled to the side cover 22, based on the gravity factor and the blocking effect of the first flange 23, the liquid can drop to the bearing surface of the electric control box 100 along the first extension 231 and the second extension 232 of the first flange 23, so that the liquid is prevented from penetrating into the accommodating cavity 100a from the joint of the chassis 10 and the cover body 20, and the waterproof performance of the electric control box 100 is improved.

Referring to fig. 11 to 12, fig. 10 is a schematic cross-sectional structure of another embodiment of an electronic control box provided in the present application; fig. 11 is a perspective view illustrating another view of the electronic control box of fig. 10. The second extension portion 232 is provided with a limiting portion 234 toward the side plate 12. The limiting portion 234 is spaced apart from the first extending portion 231. The first extension 231, the second extension 232, and the limiting portion 234 define the card slot 23a. The second flange 13 is clamped in the clamping groove 23a.

The plane of the limiting portion 234 may be parallel to the plane of the first extending portion 231 and perpendicular to the plane of the second extending portion 232. The limiting portion 234 and the first extending portion 231 are disposed opposite to each other in the first directionbase:Sub>A-base:Sub>A, and displacement of the second flange 13 in the first directionbase:Sub>A-base:Sub>A is limited bybase:Sub>A combined action of the limiting portion 234 and the first extending portion 231. At least a portion of the second extension 232 is connected between the first extension 231 and the stopper 234 to limit displacement of the second flange 13 in the second direction B-B or the third direction C-C. The displacement of the second flange 13 in the first directionbase:Sub>A-base:Sub>A and the second direction B-B, or the displacement in the first directionbase:Sub>A-base:Sub>A and the third direction C-C is restricted by the cooperation of the first extension 231, the second extension 232, and the stopper 234. The width of the clamping groove 23base:Sub>A in the first directionbase:Sub>A-base:Sub>A may be slightly larger than the thickness of the second flange 13 in the first directionbase:Sub>A-base:Sub>A, so that the second flange 13 is conveniently clamped in the clamping groove 23base:Sub>A.

In some embodiments, a sealing member may be disposed between the inner wall of the clamping groove 23a and the second flange 13, and the sealing member may function to seal the liquid, thereby further improving the waterproof performance of the electronic control box 100. When the chassis 10 and the cover 20 are mounted, the first flange 23 of the cover 20 wraps the second flange 13 of the chassis 10 on three sides, so that the liquid can slide along the first extension portion 231 and the second extension portion 232 to the receiving surface of the electronic control box 100, and cannot enter the accommodating cavity 100a, thereby improving the waterproof performance of the electronic control box 100.

The limiting portion 234 is disposed on a plane of the second extending portion 232 facing the side plate 12, rather than disposed on an end portion of the second extending portion 232, the second extending portion 232 may guide the liquid to drop onto the bearing surface of the electronic control box 100, so as to prevent the liquid from penetrating into the accommodating cavity 100a along the inner wall of the clamping groove 23a, thereby further improving the waterproof effect of the electronic control box 100.

The electric control box 100 has a wire outlet hole 100b, and the wire outlet hole 100b is opened in the side plate 12 and/or the side cover 22. The wire outlet hole 100b may be completely opened in the side plate 12 of the chassis 10; the side cover 22 may be entirely opened on the cover 20; the side plate 12 may be partially opened on the chassis 10, and the side cover 22 may be partially opened on the cover 20. The provision of the wire outlet hole 100b facilitates connection of the control board 30 with an external power source, and simultaneously facilitates electrical connection of other components inside the refrigerator 1000 with the control board 30.

Referring to fig. 12 to 13, fig. 12 is an exploded view of one embodiment of a refrigerator provided in the present application; fig. 13 is a schematic cross-sectional structure of an embodiment of a refrigerator provided herein; fig. 14 is a schematic cross-sectional structure of another embodiment of a refrigerator provided herein. The present application also provides a refrigerator 1000. The refrigerator 1000 includes a cabinet 500, an air duct cover 40, and the electronic control box 100 as previously described. The air duct cover 40 covers the top of the case 500 to form the air duct chamber 50. The electronic control box 100 is accommodated in the duct chamber 50. The duct cover 40 has an air return opening 40a and an air outlet opening 40b disposed opposite to each other. The air duct cover 40 includes air duct plates 41 disposed opposite to the air duct chamber 50, and the air return openings 40a and the air outlet openings 40b are formed in the air duct plates 41. The refrigerator 1000 further includes a radiator 51 and a fan 52, and the electronic control box 100, the radiator 51 and the fan 52 are sequentially arranged from the return air inlet 40a toward the air outlet 40b.

In some embodiments, the duct cover 40 further includes a top plate 42 connected between the duct plates 41. The return air inlet 40a includes a first return air inlet 401a and a second return air inlet 402a. The first return air inlet 401a is arranged on the air duct plate 41 on one side of the air duct cover 40, and the second return air inlet 402a is arranged on the air duct plate 41 on the other side of the air duct cover 40.

The air inlet surface of the fan 52 faces the radiator 51, and the air outlet surface faces the air outlet 40b.

When the refrigerator 1000 is placed in a wet area such as a bathroom, a swimming pool, and a fresh market, liquid may enter the air duct chamber 50 from the return air inlet 40a or from the outlet 40b. Since the accommodating chamber 100a of the electronic control box 100 is isolated from the external environment, the liquid cannot enter the accommodating chamber 100a, thereby protecting the control board 30 and guaranteeing the service life of the refrigerator 1000.

As the service life of the refrigerator 1000 increases, the waterproof sealant at the wire outlet hole 100b of the electronic control box 100 may fail, and the liquid may enter the accommodating cavity 100base:Sub>A along the wires and eventually drop to the bottom plate 11 of the chassis 10, because the control board 30 is disposed on the cover 20, and the relationship between the length H1 of the cover 20 in the first directionbase:Sub>A-base:Sub>A and the length H2 of the chassis 10 in the first directionbase:Sub>A-base:Sub>A is: h1> H2, the relationship between the length H1 of the cover 20 in the first directionbase:Sub>A-base:Sub>A and the length H0 of the control board 30 in the first directionbase:Sub>A-base:Sub>A is: h1 Not less than H0/3, and therefore, the control board 30 is spaced from the bottom plate 11 by a certain distance, and the control board 30 is not affected by liquid, thereby protecting the control board 30 and prolonging the service life of the refrigerator 1000.

The refrigerator 1000 further includes a semiconductor refrigerator 53 and a heat conductive member 54. The semiconductor refrigerator 53 includes a high temperature end and a low temperature end which are disposed opposite to each other, wherein the high temperature end is connected to the heat sink 51, and the low temperature end is connected to the heat conductive member 54. A heat conductive material is provided between the high temperature end of the semiconductor refrigerator 53 and the heat sink 51 and between the low temperature end and the heat conductive member 54. The heat conducting material can be heat conducting silica gel, heat conducting silicone grease or soft silica gel heat conducting pad and other products with high heat conductivity coefficient.

The refrigerator 1000 further includes a partition 55, the partition 55 having a first through hole 55a, the semiconductor refrigerator 53 being accommodated in the first through hole 55a, a surface of the semiconductor refrigerator 53 being flush with a surface of the partition 55.

The inner container 61 is spaced apart from the outer cover 62 to form a third cavity 62a between the inner container 61 and the outer cover 62. A thermal insulation material may be filled in the third cavity 62a to enhance thermal insulation performance of the storage chamber 60.

The housing 62 includes a top cover 621, the top cover 621 being located at the top of the case 500. The top cover 621 has a second through hole 621a corresponding to the first through hole 55 a. The second through hole 621a has a flange 621b facing the third cavity 62a, and the heat conducting member 54 abuts against the inner container 61 through the second through hole 621a and the flange 621 b. The heat-conducting member 54 should extend completely into the flange 621b such that the surface of the side of the heat-conducting member 54 facing away from the semiconductor refrigerator 53 is flush with the end face of the flange 621 b. The end surface of the heat conducting member 54 facing away from the semiconductor refrigerator 53 and the end surface of the flange 621b are abutted against the inner container 61, so that the loss of cold energy is avoided, and the energy consumption is reduced.

When the refrigerator 1000 is in an operating state, the low temperature end of the semiconductor refrigerator 53 exchanges heat with air in the storage chamber 60 through the heat conductive member 54 to absorb heat in the storage chamber 60. By supplying continuous current to the semiconductor refrigerator 53, the internal environment of the storage chamber 60 can be controlled to a low temperature, thereby realizing cooling.

In the operation process of the refrigerator 1000, condensed water may be generated on the side of the top cover 621 away from the third cavity 62a, and by disposing the control board 30 in the accommodating cavity 100a of the electronic control box 100, leakage caused by contact between the control board 30 and the condensed water can be avoided, thereby improving safety.

The refrigerator 1000 further includes a bottom case 71, and the bottom case 71 is covered on the bottom of the case 500 to form a collection chamber 70.
