As shown in fig. 1 to 5, the present embodiment provides an electronic control box 100 for controlling an operation of an external air conditioner unit, wherein a middle partition 300 is disposed in the external air conditioner unit, the middle partition 300 can separate a space for placing the electronic control box 100 in the external air conditioner unit, and has a protection and waterproof effect on the electronic control box 100, and at least one side of the electronic control box 100 can be supported on the middle partition 300, that is, the middle partition 300 can support and position the electronic control box 100 in the external air conditioner unit.

The electric control box 100 comprises an enclosure 110 and a circuit assembly 120, a containing cavity is formed inside the enclosure 110, the circuit assembly 120 can be arranged in the containing cavity, the enclosure 110 can improve the installation structure of the circuit assembly 120, and the enclosure 110 can protect the circuit assembly 120 to prevent rainwater or dust outside the electric control box 100 from entering the electric control box 100.

It can be understood that the top of the enclosure 110 may be provided with a first waterproof folded edge 113, the first waterproof folded edge 113 is located on one side of the enclosure 110 facing the middle partition 300, when the enclosure 110 is matched with the middle partition 300, the first waterproof folded edge 113 at least partially wraps the top edge of the middle partition 300, so that when the electronic control box 100 is installed in an air conditioner external unit, rainwater may be prevented from entering the installation space of the electronic control box 100 from the top of the middle partition 300 and contacting the electronic control box 100, thereby preventing external rainwater from entering the electronic control box 100, and ensuring that the circuit assembly 120 in the electronic control box 100 has a dry and clean working environment.

It should be noted that, since the first waterproof fold 113 is in contact with the top of the middle partition 300 and the top of the middle partition 300 is in a half-wrapped state, if rainwater enters from the top of the middle partition 300, the rainwater needs to bypass the first waterproof fold 113, and therefore the first waterproof fold 113 prolongs the rainwater entering path.

In addition, the circuit assembly 120 inside the electronic control box 100 may be directly installed on the inner wall of the accommodating cavity, or may be installed in the accommodating cavity through a bracket or other installation component, and the circuit assembly 120 may include electronic elements such as a control board, a reactor, a wire holder, a filter board, and the like, and specifically, the control function that can be realized according to actual needs is selected and arranged, which is not specifically limited in the embodiment of the present application.

First, the specific structure of the first waterproof fold 113 will be described in detail.

With continued reference to fig. 1 to 5, as a possible implementation manner, the first waterproof flap 113 may include a first extension 1131 and a second extension 1132, and the first extension 1131 and the second extension 1132 may respectively face different positions of the top of the middle partition 300, so as to form a half-wrapped structure.

The first end of the first extension 1131 may be connected to the top edge of the enclosure 110, and the second end of the first extension 1131 may extend toward the outside of the enclosure 110, and the enclosure 110 is matched with the middle partition 300, the first extension 1131 is located above the top of the middle partition 300, the second extension 1132 may be connected to the second end of the first extension 1131, and the second extension 1132 may extend toward the bottom of the enclosure 110, that is, the second extension 1132 is a side edge blocking the top of the middle partition 300.

It can be understood that, when the electrical control box 100 is applied to an outdoor unit of an air conditioner and is located in an outdoor environment, external rainwater or vapor may contact the outer wall of the enclosure 110 by first bypassing the second extension 1132 from the end of the second extension 1132 and then upward bypassing the middle partition 300 through the first extension 1131, so that the overall water seepage path is longer, and in this process, water drops need to flow upward against gravity, which makes the difficulty greater, so that the electrical control box 100 has a better waterproof effect in the outdoor unit of the air conditioner.

In addition, the end of the second extension 1132 may be provided with a first bending portion 1133, and the first bending portion 1133 may be bent away from the direction of the enclosure 110 relative to the second extension 1132, i.e. the first bending portion 1133 may be deflected towards the outside of the enclosure 110, so as to increase the water blocking area of the first waterproof fold 113, and further improve the waterproof effect.

It should be noted that the first bending portion 1133 may be formed by bending the end of the second extension 1132, and the bending angle of the second extension 1132 may be smaller than or equal to 90 °, for example, 10 °, 30 °, 50 °, 70 °, 90 °, and the like, so as to form a structure extending obliquely downward to the outside of the enclosure 110, and accordingly, the covered waterproof region may also extend obliquely downward, and thus, the waterproof region may have a wider waterproof region.

It can be understood by those skilled in the art that the air in the accommodating chamber can flow by arranging a driving unit in the accommodating chamber, or by using a driving unit outside the electronic control box 100, so that the air in the accommodating chamber forms positive pressure or negative pressure, and thus the air flow is driven to flow under the action of the difference between internal pressure and external pressure, and when the temperature of the flowing air flow is lower than the working temperature of the circuit assembly 120, the flowing air flow can exchange heat with the circuit assembly 120, absorb the heat of the circuit assembly 120, and achieve the heat dissipation effect. The driving unit may be a fan, and the specific heat dissipation manner is not limited in this embodiment.

Since the ventilation opening 1111 is provided, external rainwater and dust may be introduced into the receiving chamber from the ventilation opening 1111, and therefore, the waterproof cover 130 may be provided outside the ventilation opening 1111, and the waterproof cover 130 may be blocked on the ventilation opening 1111 and cover the ventilation opening 1111, which may be effective together.
