[0025] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection regulations of the country where the device is located, and with the authorization given by the owner of the corresponding device.

[0027] As shown in Figure 1 The present disclosure exemplarily provides an electric control box, which is optionally adapted to be arranged inside an air conditioner outdoor unit. The electric control box provided by the present disclosure specifically comprises a box 1 and an insect repelling module 2. The box 1 is provided with a heat dissipation grid 111, and the insect repelling module 2 is arranged at a position adjacent to the heat dissipation grid 111 of the box 1. The insect repelling module 2 can be detachably arranged on the box 1, or fixedly arranged on the box 1.

[0028] The box 1 is internally formed with a cavity to accommodate circuit boards and electronic components. The electronic components are heat generating components, which will generate heat during operation. The box 1 is usually provided with a heat dissipation grid 111 at the convection position of the heat sink. Taking the application of the electric control box in the air conditioner outdoor unit as an example, the air conditioner outdoor unit is usually directly exposed to the outdoor environment, and there is a risk that small mosquitoes will enter the interior of the electric control box through the heat dissipation grid 111. Especially in winter, the heat generated by the electronic components is easy to attract more mosquitoes to enter.

[0029] Although the heat dissipation grid 111 itself can play a certain anti-insect role, for example, the width θ of the heat dissipation port of the heat dissipation grid 111 can be configured to be less than 3㎜, the heat dissipation grid 111 in this range can block most mosquitoes from entering, and has little effect on the heat dissipation effect, but it is inevitable that mosquitoes with smaller volume can pass through the heat dissipation grid 111. In addition, the size of the outlet of the electric control box of the air conditioner outdoor unit, the air inlet hole of the compressor cavity, the air inlet hole of the handle, and the air inlet hole of the side plate louver can also be configured to be less than 3㎜.

[0030] To solve the technical problem, the electric control box provided by the present disclosure is also provided with a pest repelling module 2 for repelling mosquitoes near the electric control box. The pest repelling module 2 can use chemical repelling or physical repelling, where the chemical repelling can be a pest repellent, and the physical repelling can be ultrasonic waves. The pest repelling module 2 is arranged adjacent to the heat dissipation grille 111, so that the effective range of the pest repelling module 2 can cover the heat dissipation grille 111, which is conducive to enhancing the anti-insect effect at the heat dissipation grille. That is, the electric control box provided by the present disclosure can use the double anti-insect solutions of the heat dissipation grille 111 and the pest repelling module 2 to prevent mosquitoes from entering the inside of the electric control box through the heat dissipation grille 111, thereby improving the safety performance of the electric control box during operation.

[0031] The pest repelling module 2 can be arranged at a specific position according to the actual shape of the box body 1. For example, Figure 1 and Figure 2 As shown in some embodiments, the box body 1 can include a first wall surface 11 and a second wall surface 12 located at the side of the first wall surface 11, where the heat dissipation grille 111 is arranged along the first direction on the first wall surface 11. The first wall surface 11 and the second wall surface 12 are both provided with a pest repelling module 2, and the two pest repelling modules 2 are respectively located at the two ends of the heat dissipation grille 111 along the first direction. That is, more pest repelling modules 2 can be added according to actual needs to improve the reliability of the pest repelling effect.

[0032] For example, Figure 1 shows the first wall surface 11 of the box body 1, where the heat dissipation grille 111 is arranged in the extending direction from the left side to the right side of the drawing, and a space is reserved on the right side for installing the first pest repelling module 2. Referring to Figure 2 , the second wall surface 12 located at the left side of the box body 1 is shown, and the second pest repelling module 2 is arranged at the position of the second wall surface 12 close to the heat dissipation grille 111. In this way, the pest repelling modules 2 are arranged on the left side and the right side of the heat dissipation grille 111, so that the effective range of the pest repelling modules 2 can cover the heat dissipation grille 111 to the greatest extent.

[0033] In some embodiments, the electric control box provided by the present disclosure further comprises a heat sink 3, which can be a heat dissipation fin or a heat dissipation fin, for example. The heat sink 3 can be connected to the circuit board in the electric control box through a heat dissipation bracket or the like, thereby dissipating heat for the circuit board and the devices thereon. The heat sink 3 is arranged opposite and spaced apart from the first wall surface 11, and the projection of the heat sink 3 on the first wall surface 11 at least covers the heat dissipation grille 111. Taking the inverted transverse electric control box as an example, the electric control box spans the fan cavity and the compressor cavity of the outdoor unit of the air conditioner, wherein the heat dissipation grille 111 of the electric control box is located in the fan cavity. The negative pressure generated by the operation of the fan causes the air in the compressor cavity to flow into the electric control box, and then flows out from the heat dissipation grille 111 and dissipates heat to the heat sink 3, and finally enters the fan cavity. The projection of the heat sink 3 on the first wall surface 11 at least partially covering the heat dissipation grille 111 is beneficial to the full contact of the convection air with the heat sink 3 and the full heat dissipation of the heat sink 3.

[0034] The insect repelling module 2 is a consumable part. For example, the insect repelling agent will lose its effectiveness after a long period of use or even become ineffective. Therefore, the insect repelling module 2 needs to be replaced conveniently. In some embodiments, the outer wall surface of the box body 1 is provided with a mounting groove 112, and the insect repelling module 2 is at least partially embedded in the mounting groove 112. This embedded manner, for example, can cause the insect repelling module 2 to be slightly deformed during the process of mounting the insect repelling module 2 to the mounting groove 112, and the structure is simple and the operation is convenient. Alternatively, the insect repelling module 2 can be a combination of an insect repelling agent and a high polymer material, such as PP or ABS, which can provide a slight deformation capability.

[0035] As shown in Figure 3 and Figure 4 , in some embodiments, the inner side wall surface of the mounting groove 112 is configured as a slope that gradually expands in the direction from the outside to the inside of the box body 1, and the outer peripheral wall of the insect repelling module 2 is provided with a mounting slope 23 that can cooperate with the shape of the inner side wall surface of the mounting groove 112. In this way, the insect repelling module 2 can be embedded in the mounting groove 112 in an inverted manner, thereby restraining the insect repelling module 2 and preventing it from being removed from the mounting groove 112 without external force, thereby improving the reliability of the installation of the insect repelling module 2. In other embodiments, as shown in Figure 4 and Figure 6 , the angle α between the mounting slope 23 of the insect repelling module 2 and the plate surface of the insect repelling module 2 facing the mounting groove 112 is greater than 30°. This is beneficial to ensuring installation reliability while avoiding the problem of being difficult to install due to too small angle. In order to further improve the reliability of the installation of the insect repelling module 2, the plate surface of the insect repelling module 2 facing the mounting groove 112 can also be provided with an adhesive.

[0036] In consideration of the convenience of assembly and replacement of the insect repelling module 2, in some embodiments, as shown in Figure 1As shown, the outer wall of the box 1 is also provided with a handle groove 113 for fingers to insert. The handle groove 113 is connected to the mounting groove 112, and the handle groove 113 is recessed in the direction away from the mounting groove 112. This allows a portion of the insect repellent module to be contacted after a finger is inserted into the handle groove 113, thereby enabling the insect repellent module 2 to be pulled outward. For example, the handle groove 113 can be constructed as a crescent shape that is recessed in the direction away from the mounting groove 112.

[0037] like Figure 3 As shown, in order to maximize the insect-repelling effect of the insect-repelling module 2, in some embodiments, the insect-repelling module 2 can partially protrude from the outer wall of the box body 1, and the thickness H of the portion of the insect-repelling module 2 protruding from the outer wall of the box body 1 is greater than 1 mm. (Continue to refer to...) Figure 5 The overall thickness W of the insect repellent module 2 can be, for example, 2 mm. This ensures that the portion of the insect repellent module 2 protruding from the outer wall is thick enough to fully exert its insect repellent effect, while still having enough portion inside the mounting slot 112 to ensure the reliability of the installation of the insect repellent module 2.

[0038] According to a second aspect of the present disclosure, an air conditioner outdoor unit is also provided, which includes the electrical control box of any of the above-mentioned items and has all of its beneficial effects, which will not be repeated here.

[0039] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation.
