The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-4, the present invention provides an electrical box, which includes a body 1 and a box cover 2 that can be fastened to the body 1, where the body 1 is used to install electrical components necessary for air conditioner operation, including a driving board, a control board, a filter board, a reactor, a terminal strip, and the like; the box cover 2 is used for being buckled on the body 1, and a containing space capable of containing the electric parts is formed after the box cover 2 and the body 1 are buckled. The bottom of lid 2 is provided with air inlet 21, the top of body 1 is provided with gas outlet 11. The electric box adopts the heat dissipation mode from bottom to top, helps with the electric part heat dissipation of electric box inside more complete.
As shown in fig. 2 and fig. 3, a heat dissipation channel 13 is formed at the air outlet 11 of the body 1 according to the present invention, the heat dissipation channel 13 is a hollow channel formed by the top of the body 1 protruding from the body 1 and extending toward the back of the body 1, and a wind deflector 3 is disposed on the body 1 corresponding to the bottom of the opening of the heat dissipation channel 13.
According to the arrangement of the middle heat dissipation channel, the return bend from the outside of the electric box or from rainwater or insects to the inside of the electric box is increased, so that the resistance to rainwater and insects is increased; in addition, the baffle capable of changing the air flow direction is arranged at the outlet of the heat dissipation channel, so that the air flow in the air conditioner body is prevented from flowing backwards into the air box, and the heat dissipation efficiency is improved; meanwhile, the flowing backward air flow is prevented from carrying rainwater into the electric box, and a waterproof effect is achieved. Through the cooperation setting of above-mentioned heat dissipation channel and deep bead, further avoided rainwater and insect to get into the probability to electric box inside to the life of electric spare has been prolonged.
Specifically, the body 1 includes a back plate vertically disposed, and an upper cover disposed on the top of the back plate, the heat dissipation channel is a hollow space formed between the top of the back plate and the upper cover, and the back plate and the upper cover are preferably connected by spot welding.
In order to further prevent water from entering the heat dissipation channel and spreading to the cavity of the electrical box, at least one rib 12 is arranged at the top of the body 1 corresponding to the heat dissipation channel 13. The convex ribs 12 are higher than the top of the body 1, transversely arranged in the heat dissipation channel 13 and formed into a barrier belt in the heat dissipation channel, so that secondary rainwater blocking is realized.
Since the air flow channel of the electrical box of the present invention is from bottom to top, preferably, the transverse width of the wind deflector 3 is greater than the opening width of the heat dissipation channel 13, so as to prevent air outside the electrical box from entering the heat dissipation channel.
As shown in fig. 4, the box cover 2 of the present invention is provided with an elastic pad 5 capable of sealing the wire 4 corresponding to the air inlet 21. Because of the wire of electric box from air inlet department with external connection, consequently, the hole of accessible wire need be reserved to the air inlet department of electric box, but because of the existence in this hole, easily lead to the entering of rainwater or insect, consequently, set up elastic cushion on the one hand and can not cause the damage to the wire, on the other hand can play sealed effect.
As shown in fig. 3, it is preferable that the height of the front surface of the body 1 is greater than the height of the rear surface of the body 1. Therefore, the heat dissipation channel is in an inclined state, and the resistance of rainwater is larger when the rainwater enters the heat dissipation channel.
Preferably, the air inlets 21 are a plurality of holes formed in the box cover 2. The air outlets 11 are a plurality of holes formed in the body 1. The diameter of the hole of the air inlet 21 and/or the hole of the air outlet 11 is less than 3 mm. The small-hole-shaped air inlet and the small-hole-shaped air outlet can prevent ladybug insects from entering the electric box to cause short circuit of an electric part.
As shown in fig. 5, the present invention further provides an air conditioner, which includes an indoor unit and an outdoor unit, wherein the electrical box according to any of the above embodiments is disposed in the outdoor unit. Therefore, the detailed description is omitted here.
Further, the outdoor unit comprises a heat exchanger 7 arranged on the side of the outdoor unit and a fan 6 arranged on the top of the outdoor unit, and the electrical box is vertically arranged on the inner side wall of the outdoor unit.
The air conditioner comprises the electric box with the wind shield and the heat dissipation channel, and when the top fan is started, airflow enters the heat dissipation channel through the air outlet at the top of the electric box and flows backwards after reaching the upper part of the electric box, and flows downwards along the heat dissipation channel. And the arrangement of the wind shield prevents the air outlet of the electric box from generating opposite impact with the total air flow in the air conditioner outdoor unit, and enhances the air outlet flow.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
