Abstract

Technical Field
[0001] The utility model relates to a waterproof and ventilating structure, in particular to a waterproof and ventilating housing structure for an electrical product. Background Art
[0002] The variable frequency controller in the outdoor unit of an air conditioner is an element that is prone to damage. The main reason is its poor heat dissipation ability, and it is in the outdoor for a long time. When the weather is hot, the heat dissipation requirement for the variable frequency controller is even higher. Currently, the heat dissipation method of the variable frequency controller is to open multiple heat dissipation holes on its housing. In order to prevent rainwater from entering the variable frequency controller, at this time, the variable frequency controller needs to be installed in an installation box with a rainproof function. However, such an operation not only increases the use cost of the variable frequency controller, but also the space in the installation box is narrow, which is not conducive to heat dissipation. Therefore, there is an urgent need to develop a housing structure that has both waterproof and ventilating effects, so that the variable frequency controller or other components that need heat dissipation and waterproofing can be installed in this housing structure, reducing the user's use cost and improving the heat dissipation and waterproofing ability of the variable frequency controller or other components.

[0005] Further, the housing is a square housing, and the concave portion is provided at a corner of the lower end of the outer side of the housing.
[0006] Further, the housing includes a housing bottom surface and side surfaces surrounding the periphery of the housing bottom surface; the concave portion has a concave portion bottom surface, a first side surface and a second side surface.

[0015] As Figure 1 and Figure 3 shown, in this embodiment, the present utility model includes a housing 1. An open mouth 2 is provided at the upper end of the housing 1, a recess 3 is provided at the lower end of the housing 1, and a plurality of heat dissipation holes 4 communicating with the inside of the housing 1 are provided in the recess 3. A rain shield 5 corresponding to each of the heat dissipation holes 4 is further provided on the recess 3. In this embodiment, by providing the heat dissipation holes 4 on the recess 3 and the heat dissipation holes 4 facing downward during installation, heat can be dissipated and rainwater can be prevented from easily entering the housing 1. At the same time, with the assistance of the design of the rain shield 5, the waterproof performance of the present utility model can be further improved.
[0016] In this embodiment, the housing 1 is a square housing, and the recess 3 is provided at a corner of the lower end of the outer side of the housing 1. By providing the recess 3 at a corner of the lower end of the outer side of the housing 1, a front eaves for avoiding rainwater can be formed by using the housing 1 itself.
[0017] As Figure 2As shown, in this embodiment, the housing 1 includes a housing bottom surface 11 and a side surface 12 surrounding the periphery of the housing bottom surface 11; the recess 3 has a recess bottom surface 31, a first side surface 32, and a second side surface 33. The recess bottom surface 31 is parallel to the housing bottom surface 11, and both the first side surface 32 and the second side surface 33 are perpendicular to the recess bottom surface 31. Four of the heat dissipation holes 4 are provided on the first side surface 32. In this embodiment, the heat dissipation holes 4 are strip-shaped holes, and the length direction of the strip-shaped holes is perpendicular to the recess bottom surface 31. Through such a design, the four large strip-shaped heat dissipation holes 4 can dissipate heat well, improving the heat dissipation effect.
[0018] In this embodiment, a rain shield 5 and a water stop 6 are respectively provided on both sides of each of the strip-shaped holes. The inner ends of the rain shield 5 and the water stop 6 are both perpendicularly connected to the recess bottom surface 31. The outer ends of the rain shield 5 and the water stop 6 are both flush with the housing bottom surface 11. The lower end of the rain shield 5 is connected to the first side surface 32. The upper end of the rain shield 5 is bent and buckled on one side of the outer side surface of the water stop 6. The inner side surface of the water stop 6 is close to its corresponding strip-shaped hole. In this embodiment, through the design of the rain shield 5 and the water stop 6, rainwater can be well prevented from entering the strip-shaped holes, further improving the waterproof performance of the present utility model.
[0019] In this embodiment, there is a first ventilation gap 7 between the upper end of the rain shield 5 and the first side surface 32, and there is a second ventilation gap 8 communicating with the first ventilation gap 7 between the upper end of the rain shield 5 and the outer side surface of the water stop 6. In this embodiment, through the first ventilation gap 7 and the second ventilation gap 8, the heat dissipation amount inside the housing 1 can be well increased, providing multiple channels for heat dissipation.
[0020] In this embodiment, the upper end of the outermost rain shield 5 is hermetically connected to the first side surface 32. Since the outermost rain shield 5 is often subjected to the greatest impact of rainwater, through the above design, rainwater can be well prevented from seeping in through the outermost rain shield 5.
[0021] As Figure 4 shown, when in use, the open end 2 is buckled on the mounting base, thereby encapsulating the component a mounted on the base inside the housing 1. The component a generates a large amount of heat during operation, and can dissipate heat naturally through the heat dissipation holes 4 or by installing a heat dissipation fan. At the same time, through the design of the rain shield 5 and the water stop 6, rainwater can be well prevented from entering the housing 1, which can not only prevent water but also ventilate, with low usage cost and can effectively extend the service life of the component a.
[0022] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
