Detailed description of the invention
In the following description, give a large amount of concrete details to provide to understand more thoroughly the utility model.But, it will be apparent to one skilled in the art that the utility model embodiment can be implemented without the need to these details one or more.In other example, in order to avoid obscuring with the utility model embodiment, technical characteristics more well known in the art are not described.
In order to thoroughly understand the utility model embodiment, by following description, detailed structure is proposed.Obviously, the execution of the utility model embodiment is not limited to the specific details that those skilled in the art has the knack of.Better embodiment of the present utility model is described in detail as follows, but except these are described in detail, the utility model can also have other embodiments.
As shown in Figure 1, the utility model provides a kind of anti-condensation electric cabinet 1, and it can be used for frequency-variable air conditioner outdoor machine group.This anti-condensation electric cabinet 1 comprises electronic-control box 12, lamina tecti 11 and deflector 20 (not shown in Figure 1).Electronic-control box 12 comprises two side plates 123 and base plate 124, and its inside is provided with electric elements.
Lamina tecti 11 is arranged on the top of electronic-control box 12, deflector 20 is arranged between lamina tecti 11 and electronic-control box 12, deflector 20 and lamina tecti 11 interval are arranged, the both sides of deflector 20 are provided with side flanging 21, deflector 20 is connected with electronic-control box 12 by side flanging 21, the front end of deflector 20 is provided with the front end flanging 22 upwards bent, and the rear end of deflector 20 is provided with the rear end flanging 23 of bending downwards.
According to anti-condensation electric cabinet of the present utility model, for frequency-variable air conditioner outdoor machine group, can reliably by Leads to new breeze frequency-variable air conditioner outdoor machine group, can ensure that again the top of the anti-condensation electric cabinet when the extreme sleety weather of unexpected generation condensation can not occur, even if or there is a small amount of condensation, the globule also can not drop onto on electrical equipment and cause electrical safety accident.Fresh wind port structural design can not only meet the cooling requirements of anti-condensation electric cabinet but also effectively can accomplish waterproof; And only use one piece of deflector just effectively can solve condensation problem, improve the security performance of anti-condensation electric cabinet.
Deflector 20 can be made up of metal material, also can be made up of the nonmetallic materials of such as ABS plastic.
With reference to figure 3 to Fig. 5, deflector 20 and lamina tecti 11 interval are arranged, and are formed with the space of a hollow between itself and lamina tecti 11, and the height H scope in this space can be arranged as required, be such as 8-25mm, namely between deflector 20 and lamina tecti 11, interval 8-25mm is arranged.Further, the insulation material of such as heat-preservation cotton can be filled in the space of this hollow, to play the effect of insulation.
As shown in Figure 2, deflector 20 left and right sides is provided with side flanging 21, and side flanging 21 bends downwards.In the shown embodiment, two side flanging 21 settings substantially vertical with deflector 20 respectively, and be enclosed within the side plate 123 of electronic-control box 12 downwards, and be fixed on electronic-control box 12 by rivet 30 (Fig. 6), like this, electronic-control box 12 can be reinforced on the one hand, on the other hand, when having a small amount of condensation water to occur when between lamina tecti 11 and deflector 20, effectively stop that condensation water enters anti-condensation electric cabinet 1 from the left and right sides.
Described in detail by Fig. 4, deflector 20 has in the front end of anti-condensation electric cabinet 1 and is provided with one section of front end flanging 22 upwards, and this front end flanging 22 can be connected with deflector 20 is vertical, and its length of extending deflector 20 can be 7-20mm.Can certainly be other numerical value, when there being a small amount of condensation water to occur, front end flanging 22 effectively can stop that condensation water enters anti-condensation electric cabinet 1 from the front end of anti-condensation electric cabinet 1.
Continue with reference to Fig. 4, deflector 20 has rear end flanging 23 in the rear end of anti-condensation electric cabinet 1, in the shown embodiment, rear end flanging 23 is 30 ° of angles relative to the angle of inclination a of deflector 20, certainly, angle of inclination a also can be other angle, such as 25 °-35 °.
In addition, rear end flanging 23 bends distance h is downwards 10mm.The water conservancy diversion effect of rear end flanging 23 can be ensured like this.In addition, the relevant position on electronic-control box 12 also can be provided with the connecting portion 122 stretched out to casing extension, and rear end flanging 23 and this connecting portion 122 are fixed by the connector of such as self threading pin, to make the structure of rear end flanging 23 more firm.
With reference to figure 4, the rear end of electronic-control box 12 is provided with fresh wind port 120.Temperature drift in air conditioner control cabinet, affect performance and the life-span of electric components in control cabinet, rotated by outdoor unit fan (motor) and the fresh air of outdoor environment temperature introduced control cabinet via fresh wind port 120 and blows out outside air conditioner, can effectively reduce the temperature of control cabinet and reach design requirement.And the rear end flanging 23 of deflector 20 is arranged on the upper end of fresh wind port 120, the lower end of fresh wind port 120 is provided with the fresh wind port flanging 121 extended outside electronic-control box 12.Rear end flanging 23 and fresh wind port flanging 121 can form effective fresh flue, reduce windage.When having a small amount of condensation water to occur when between lamina tecti 11 and deflector 20, this flanging effectively can stop that condensation water enters anti-condensation electric cabinet 1 from electronic-control box rear end, simultaneously can effective drainage to condensed water, flow out from the downward flanging gap of deflector 20 with lamina tecti 11 rear end.
By the three-dimensional cross-over design of fresh wind port flanging 121 with rear end flanging 23, fresh wind port flanging 121 and rear end flanging 23 are in different height, preferably, and the downward distance of the bending of fresh wind port flanging 121 can be greater than the bending distance h downwards of rear end flanging 23, both are interlaced to form fan electromotor water dumping water column reflection dead angle like this.Both can ensure that the resh air requirement of unit reached the requirement of controller, and in turn ensure that in rainy situation, the run up water column that throws away of electric fan can not enter the inside of anti-condensation electric cabinet 1 by fresh wind port 120, ensure that unit safety.Simultaneously; because rear end flanging 23 and deflector 20 tilt certain angle (such as 30 °); can ensure under rainy day rain working condition; due to 30 ° of knuckles and the Action of Gravity Field of deflector 20; the electric fan water got rid of inside deflector 20 flanging that runs up can flow to outside electronic-control box 12 along flanging, guarantees unit safety.
The utility model is illustrated by above-mentioned embodiment, but should be understood that, above-mentioned embodiment just for the object of illustrating and illustrate, and is not intended to the utility model to be limited within the scope of described embodiment.In addition it will be understood by those skilled in the art that; the utility model is not limited to above-mentioned embodiment; more kinds of variants and modifications can also be made, within these variants and modifications all drop on the utility model scope required for protection according to instruction of the present utility model.
