[0048] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0049] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0050] In combination Figure 1 As shown, for the air conditioner outdoor unit 13 that ejects air, the air supply system 131 is arranged at the top of the outdoor unit 13. The air supply system 131 includes a motor, a fan, a wind ring, etc. The top cover of the outdoor unit 13 is provided with an air inlet 132 directly communicating with the outside, and the electrical control box 1 of the air conditioner outdoor unit 13 is arranged at the upper middle part of the outdoor unit 13, below the air supply system 131. In high humidity, rain, snow and other weather conditions, condensate water, rain and snow water will directly pour onto the electrical control box 1. If the electrical control box 1 is not well sealed, the condensate water, rain and snow water will enter the electrical control box 1, causing the electrical components in the electrical control box 1 to short circuit and burn out, and even cause the entire machine to catch fire, causing property and personnel losses. Therefore, the water guide design of the electrical control box 1 is particularly important.

[0051] The related art is mostly to guide water outside the electric control box 1, but there is no corresponding design for water entering the inside of the electric control box 1. The accumulated water in the electric control box 1 cannot be drained and can only rely on the high temperature generated by the electric components in the electric control box 1 to evaporate the water. However, the electric components work in the case of accumulated water in the box, which has safety hazards and is very easy to cause short circuit, damage or even burn of the electric components. In addition, when the accumulated water is too much, the service life of the electric components is greatly shortened.

[0052] In combination with Figure 2 The electric control box 1 provided by the embodiments of the present disclosure includes a box body 2, the box body 2 defines a mounting space 3, the bottom of the mounting space 3 is provided with a drainage channel 4, and the box body 2 is provided with a drainage port 5 in communication with the drainage channel 4. The electric control box 1 further includes electric components 6, and the electric components 6 are arranged in the mounting space 3. The electric control box 1 further includes a drainage fan 7, and the drainage fan 7 is arranged in the box body 2. The drainage fan 7 is used to drive the water in the mounting space 3 to flow out through the drainage channel 4 and the drainage port 5 in sequence.

[0053] The electric control box 1 provided by the embodiments of the present disclosure is adopted. The drainage channel 4 is arranged at the bottom of the mounting space 3, the drainage port 5 is arranged on the box body 2, the drainage port 5 is in communication with the drainage channel 4, the water entering the box body 2 of the electric control box is blown by the drainage fan 7, the water flows along the drainage channel 4 under the driving of the drainage fan 7, and flows out of the box body 2 through the drainage port 5. The drainage speed of the accumulated water in the electric control box 1 is improved, the loss of the electric components 6 is reduced, and the service life of the electric components 6 is increased.

[0054] Optionally, in combination with Figure 3 and 4 The electric control box 1 further includes a support plate 8, and the support plate 8 is located in the mounting space 3. The support plate 8 includes a first side plate 81 and a bottom plate 82 located at the bottom of the first side plate 81. The first side plate 81 divides the mounting space 3 into a first sub-mounting space 31 and a second sub-mounting space 32. The electric components 6 are arranged in the first sub-mounting space 31, and the bottom plate 82 is located in the second sub-mounting space 32 and the drainage channel 4 is arranged on the bottom plate 82.

[0055] In this way, the mounting space 3 is divided into the first sub-mounting space 31 and the second sub-mounting space 32 by the support plate 8. The electric components 6 are arranged in the first sub-mounting space 31, and the drainage channel 4 is arranged in the second sub-mounting space 32. The electric components 6 are separated from the drainage channel 4. The influence of the accumulated water in the box body 2 on the electric components 6 during the process of flowing out of the box body 2 is reduced, the loss of the electric components 6 is reduced, and the service life of the electric components 6 is increased.

[0056] Optionally, the box 2 comprises a first box side plate 21 and a second box side plate 22. The first box side plate 21 and the second box side plate 22 are oppositely arranged, the first side plate 81 is clamped between the first box side plate 21 and the second box side plate 22, and the first side plate 81 and the drainage channel 4 both extend in the direction from the first box side plate 21 to the second box side plate 22, and the drainage fan 7 is located upstream of the drainage channel 4. It can be understood that the upstream and downstream of the drainage channel 4 are named according to the flow direction of the water flow.

[0057] In this way, the drainage fan 7 blows the accumulated water in the box 2 to the downstream of the drainage channel 4 upstream of the drainage channel 4, and then to the outside of the electric control box 1 through the drainage port 5, so as to realize the drainage of the accumulated water in the electric control box 1 to the outside of the electric control box 1.

[0058] Optionally, the drainage fan 7 is arranged on the first box side plate 21, and the drainage port 5 is arranged on the second box side plate 22.

[0059] Because the first box side plate 21 and the second box side plate 22 are oppositely arranged, the drainage fan 7 is arranged opposite to the drainage port 5, and because the drainage channel 4 is arranged in the direction from the first box side plate 21 to the second box side plate 22, the air of the drainage fan 7 blows directly to the drainage channel 4 and the drainage port 5. In this way, the drainage fan 7 blows directly, which can obtain the maximum air speed and the minimum air loss, accelerate the speed of the accumulated water to drain out of the box 2, and reduce the safety hidden danger caused by the long-term soaking of the water in the electric control box 2.

[0060] Optionally, the support plate 8 further comprises a second side plate 83 and a third side plate 84. The second side plate 83 and the third side plate 84 are oppositely arranged, the first side plate 81 is clamped between the second side plate 83 and the third side plate 84 and extends in the direction from the second side plate 83 to the third side plate 84, and the drainage channel extends in the direction from the second side plate 83 to the third side plate 84.

[0061] Optionally, the second side plate 83 is arranged on the inner side of the first box side plate 21 and is attached to the first box side plate 21, so as to reduce the gap between the second side plate 83 and the first box side plate 21 and avoid rainwater flowing into the installation space from the gap above.

[0062] The third side plate 84 is arranged on the inner side of the second box side plate 22 and is attached to the second box side plate 22, so as to reduce the gap between the third side plate 84 and the second box side plate 22 and avoid rainwater flowing into the installation space from the gap above.

[0063] Optionally, the drainage fan 7 is arranged on the second side plate 83.

[0064] In this way, the drainage fan 7 is arranged on the support plate 8 instead of the box body 2, so that the sealing performance of the electric control box 1 is improved, and rain and snow water cannot enter the electric control box 2 through the installation position of the drainage fan 7, so that the electric components 6 are prevented from being damaged.

[0065] Optionally, the third side plate 84 is connected with the bottom plate 82, and a drainage channel 85 is formed at the connection position.

[0066] In this way, the water in the box body 2 flows out of the electric control box 2 through the drainage channel 4, the drainage channel 85 and the drainage port 5 in sequence, and the water in the electric control box 2 is drained.

[0067] Optionally, as shown in Figure 4 the bottom plate 82 includes a first bottom plate 821 and a second bottom plate 822. The first bottom plate 821 and the second bottom plate 822 are arranged in sequence in the direction from the first sub-mounting space 31 to the second sub-mounting space 32, and the first bottom plate 821 is higher than the second bottom plate 822. The upper surface of the first bottom plate 821 forms a first sub-drainage channel 41, and the upper surface of the second bottom plate 822 forms a second sub-drainage channel 42. The first sub-drainage channel 41 and the second sub-drainage channel 42 are connected in communication, and the drainage channel 4 includes the first sub-drainage channel 41 and the second sub-drainage channel 42.

[0068] The first sub-drainage channel 41 and the second sub-drainage channel 42 are connected in communication, and the first sub-drainage channel 41 is higher than the second sub-drainage channel 42. In this way, the water in the first sub-drainage channel 41 can flow to the second sub-drainage channel 42 under the action of gravity, and then flow out of the electric control box 2 through the drainage channel 85 and the drainage port 5 in sequence, so that the water in the first sub-drainage channel 41 is prevented from being accumulated.

[0069] Optionally, the electric control box 1 further includes a water immersion detection device 14 arranged in the second sub-mounting space 32 and configured to detect the water accumulation in the second sub-mounting space 32.

[0070] Optionally, the water immersion detection device 14 is a water immersion sensor.

[0071] The working principle of the water immersion sensor is as follows: the water immersion sensor is based on the liquid conductivity principle. The electrode is used to detect whether there is water. When water is present, the two sensing lines of the cable are short-circuited, so that the current changes. According to the proportional relationship between the resistance and the length of the conductor, the specific leakage position is given through the controller, and an alarm information is sent at the same time.

[0072] Optionally, the water immersion sensor includes a double-point detection needle structure.

[0073] In this way, based on the principle of liquid conduction, when water enters the second sub-mounting space 32, the double-point detection needle is connected, the water immersion sensor is started and sends a signal to the corresponding device through the connecting line.

[0074] Optionally, the water immersion sensor is a contact type water immersion sensor.

[0075] The contact type water immersion sensor detects by direct contact between the sensor and the liquid. The basic principle of the contact type water immersion sensor is that the sensor is placed at the position to be detected. When the sensor comes into contact with the liquid, the circuit in the sensor detects the change of the resistance value, and then triggers the alarm device to issue an alarm information. The contact type water immersion sensor has the characteristics of high detection accuracy and fast alarm time.

[0076] Optionally, the contact type water immersion sensor adopts a double power supply mode, which includes self-storage battery power supply and whole machine weak power supply. In the case of whole machine weak power supply, the self-storage battery of the contact type water immersion sensor is charged. After the capacity of the self-storage battery is saturated, the whole machine weak power supply is still used preferentially. In the case of whole machine power failure, the contact type water immersion sensor will work by self-storage battery power supply.

[0077] Optionally, the first sub-drainage channel 41 is provided with a first contact type water immersion sensor 141, and the second sub-drainage channel 42 is provided with a second contact type water immersion sensor 142. The water immersion detection device 14 includes the first contact type water immersion sensor 141 and the second contact type water immersion sensor 142.

[0078] In this way, the first contact type water immersion sensor 141 can detect the water accumulation condition of the first sub-drainage channel 41, and the second contact type water immersion sensor 142 can detect the water accumulation condition of the second sub-drainage channel 42.

[0079] Optionally, the upper surfaces of the first bottom plate 821 and the second bottom plate 822 are inclined downward in the direction from the first sub-mounting space 31 to the second sub-mounting space 32.

[0080] Because the upper surface of the first bottom plate 821 forms the first sub-drainage channel 41, and the upper surface of the second bottom plate 822 forms the second sub-drainage channel 42, the upper surfaces of the first bottom plate 821 and the second bottom plate 822 are inclined downward in the direction from the first sub-mounting space 31 to the second sub-mounting space 32. Therefore, the first sub-drainage channel 41 and the second sub-drainage channel 42 are inclined downward in the direction from the first sub-mounting space 31 to the second sub-mounting space 32. In this way, the downwardly inclined drainage channel 4 is conducive to drainage and facilitates the flow of water away from the first sub-mounting space 31, i.e., the water in the first sub-drainage channel 41 flows to the second sub-drainage channel 42, reducing the risk of water penetration from the second sub-mounting space 32 to the first sub-mounting space 31, and better protecting the electrical components 6 and the electrical safety of the whole machine.

[0081] Optionally, the box 2 comprises a third box side plate 23, the third box side plate 23 is arranged opposite to the first side plate 81, and the bottom plate 82 is located between the third box side plate 23 and the first side plate 81. As shown in Figure 4 The electric control box 1 further comprises a duct cover plate 9 arranged above the bottom plate, the duct cover plate 9 is provided with a through hole 91, wherein the duct cover plate 9, the bottom plate 82, the third box side plate 23 and the first side plate 81 jointly define a duct 92, and the drainage channel 4 is located in the duct 92.

[0082] The drainage channel 4 is located in the duct 92, and the air outlet of the drainage fan 7 is opposite to the duct 92, so that the positive wind generated by the drainage fan 7 blows and drains the accumulated water on the drainage channel 4, and the accumulated water is drained to the drainage channel 85 away from the electrical element 6, and then is discharged from the box 2 through the drain 5, so that the amount of accumulated water in the box 2 is reduced, and the risk of soaking the electrical element 6 is reduced.

[0083] Optionally, the through hole 91 is located on the side of the duct cover plate 9 close to the first side plate 81.

[0084] Optionally, as shown in Figure 5 The electric control box 1 further comprises an electric control processor 15, and at least one of a warning device 16, a linkage device 17, a drainage device 18 and a cloud service module 19. The at least one of the warning device 16, the linkage device 17, the drainage device 18 and the cloud service module 19 is connected with the electric control processor 15. The electric control box 1 detects the accumulated water in the box 2 through the water immersion detection device 14, transmits information to the electric control processor 15, and after logical analysis and judgment according to predetermined parameters, issues an instruction to the warning device 16 and / or the linkage device 17, and sends information to the cloud service module 19. The warning device 16 makes corresponding warning reminders to remind the user of the accumulated water, and the linkage device 17 executes the starting of the drainage device 18 and / or the power-off action of the whole machine according to the pre-set logic, to ensure the safety and stability of the electric control box 1 of the air conditioner outdoor unit 13 during operation. The drainage device 18 comprises the drainage fan 7, the duct 92 and the drainage channel 85, and the electric control processor 15 is a system composed of multiple components.

[0085] Optionally, the linkage device 17 is an electric control device, an air switch, a circuit breaker or other components that can perform electric control. After receiving the instruction issued by the electric control processor 15, the linkage device 17 executes the corresponding starting of the drainage fan 7 and / or the power-off action of the whole machine (air conditioner) according to the pre-set logic.

[0086] Optionally, the warning device 16 comprises a loudspeaker and an indicator light, and after receiving the instruction issued by the electric control processor 15, the warning device 16 executes the whistling and flashing of the indicator light, to play a warning role.

[0087] Optionally, the cloud service module 19 is connected with the electric control processor 15, for receiving instructions of the electric control processor 15, and / or issuing instructions to the electric control processor 15. For example, the cloud service platform module 19 comprises a wireless unit module connected with the electric control processor 15, which can communicate with the internal and external machines, and can also communicate information and instructions through the Internet and servers, cloud service platforms, APPs of maintenance personnel terminals, etc., to realize bidirectional intercommunication, i.e., the data collected by the product front end can be transmitted to the terminal, and the instructions issued by the terminal can be transmitted to the product processor system, so as to complete the operation corresponding to the instructions.

[0110] In the embodiments of the present disclosure, the second contact type water immersion sensor 142 is located relatively low in the box body 2, and thus when the electric control processor 15 determines that there is a water immersion problem, it is considered that the water inlet condition of the electric control box 1 is generally solved by the cooperation of the drainage device 18 and the water outlet 5 in the box body, and the positive wind generated by the drainage fan 7 blows and drains the accumulated water on the water drainage channel 4 along the air duct 92 to the water drainage channel 85 away from the electrical element 6, and then the water is discharged from the box body 2 through the water outlet 5, so that the amount of accumulated water in the box body 2 is reduced, and the risk of immersion into the electrical element 6 is reduced.

[0111] Optionally, as shown in Figure 3 The electric control box 1 further comprises a water guide plate 11, and the water guide plate 11 is arranged above the first sub-mounting space 31; wherein the water guide plate 11 is arranged in an inclined manner, and the water guide plate 11 is inclined downward along the direction from the first sub-mounting space 31 to the second sub-mounting space 32.

[0112] In this way, by using the inclination angle of the water guide plate 11, as shown by the water drainage slope A shown in Figure 3 , the condensed water, rain and snow water and the like falling on the water guide plate 11 can be made to flow into the second sub-mounting space 32, so that the water is away from the first sub-mounting space 31 where the electrical element 6 is located, and the safety of electricity use is ensured.

[0113] In the foregoing embodiments, the air duct cover plate 9 is provided with a through hole 91, so that the water inlet at the top of the electric control box 1 enters the water drainage channel 4 in sequence through the water guide plate 11 and the through hole 91, and then cooperates with the drainage fan 7 and the air duct 92 to discharge the water falling into the water drainage channel 4 from the box body 2 through the water drainage channel 85 and the water outlet 5. The water guide plate 11 is designed as a water guide at the top of the electric control box 1, and the water drainage channel 4 is designed as a water guide in the internal mounting space 3 of the electric control box 1, and the two are cooperated to better guide the water in the electric control box 1, reduce the risk of condensed water, rain and snow water and the like contacting the electrical element 6, and reduce the damage risk of the electric control box 1 during operation. In addition, the cooperation of the drainage fan 7 can improve the drainage speed of the accumulated water in the electric control box 1.

[0114] Optionally, the upper surface of the water guide plate 11 is provided with a water drainage groove 111, and the water drainage groove 111 extends along the direction from the first sub-mounting space 31 to the second sub-mounting space 32.

[0115] The inner wall surface of the water drainage groove 111 forms the lowest surface of the upper surface of the water guide plate 11.

[0116] The water drainage groove 111 is arranged on the upper surface of the water guide plate 11, and the inner wall surface of the water drainage groove 111 is the lowest surface of the upper surface of the water guide plate 11, so that the condensed water, rain and snow water and the like falling on the water guide plate 11 are easily collected in the water drainage groove 111 and flow to the second sub-mounting space 32 through the water drainage groove 111, and the drainage position is relatively fixed, which is convenient for control.

[0117] Optionally, as shown inFigure 3 As shown, the water guide plate 11 includes a water guide plate body 112 and a plug plate 113. The plug plate 113 is arranged adjacent to the water guide plate body 112. The plug plate 113 is inserted into the second sub-installation space 32 and abuts against the first side plate 81 of the support plate 8. The drainage groove 111 is provided on the water guide plate body 112.

[0118] By setting the plug plate 113, water in the drain trough 111 flows down along the first side plate 81, preventing splashing onto the electrical components 6.

[0119] Optionally, the electrical control box 1 also includes a cover plate 12, which covers the first sub-installation space 31 and the second sub-installation space 32, and is located above the water guide plate 11.
