DETAILED DESCRIPTION

[0053] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] Please refer to Figures 1 to 20 The present invention provides a waterproof device, which is used to be installed on the side wall of an electrical box 1. A heat exchanger 2 is provided on the side wall of the electrical box 1. The waterproof device and the heat exchanger 2 are located on the same side of the electrical box 1. The waterproof device includes a guide component 3 and a waterproof component 4. The guide component 3 is used to be installed on the electrical box 1, and the guide component 3 extends along a predetermined track; at least a portion of the waterproof component 4 is installed on the guide component 3, and the waterproof component 4 is movably arranged along the extension direction of the guide component 3 so that the waterproof component 4 can switch between an initial state and a waterproof state.

[0055] Among them, when the waterproof component 4 is in a waterproof state, at least part of the waterproof component 4 is blocked on the upper side and / or lower side of the heat exchanger 2 to block the gap between the heat exchanger 2 and the electrical box 1; when the waterproof component 4 is in the initial state, the waterproof component 4 forms an avoidance channel for avoiding the airflow located on the side of the electrical box 1, so that the airflow located on the side of the electrical box 1 passes through the waterproof component 4 through the avoidance channel.

[0056] The waterproof device in the present invention includes a guide component 3 and a waterproof component 4. By setting the guide component 3 and the waterproof component 4, the waterproof component 4 can switch between the initial state and the waterproof state along the predetermined trajectory of the guide component 3; when the waterproof component 4 is in the waterproof state, the waterproof component 4 blocks the upper side and / or lower side of the gap between the heat exchanger 2 and the electrical box 1, thereby preventing water from flowing into the electrical box 1 from the gap between the heat exchanger 2 and the electrical box 1; when the waterproof component 4 is in the initial state, the airflow on the side of the electrical box 1 can flow normally through the avoidance channel, thereby solving the problem in the prior art that water is easily ingressed through the heat dissipation opening in the electrical box arranged in the air conditioner outdoor unit.

[0057] In order to enable the waterproof component 4 to switch between the initial state and the waterproof state, the guide component 3 has a guide portion, which is arranged around the heat exchanger 2. The waterproof component 4 has a baffle component 47, which cooperates with the guide portion to be movably arranged along the guide portion to enable the waterproof component 4 to switch to the initial state or the waterproof state.

[0058] Specifically, the specific structure of the guide portion in this embodiment is:

[0059] In one structure, the guide portion is a guide groove, and the baffle member 47 has an inserting portion 46 for inserting into the guide groove. Such an arrangement enables the baffle member 47 to move along the extending direction of the guide groove.

[0060] Another structure is that the guide portion is a guide protrusion, and the baffle member 47 has an insertion groove for the guide protrusion to be inserted into. Such an arrangement enables the guide protrusion to drive the baffle member to move along the extending direction of the guide portion.

[0061] like Figure 5 As shown, the guide assembly 3 in this embodiment has an inner guide groove and an outer guide groove, the inner guide groove being located inside the outer guide groove, and both the inner guide groove and the outer guide groove being arranged around the heat exchanger 2; the waterproof assembly 4 includes an inner baffle 41 and an outer baffle 42, which are movably mounted in the inner guide groove and the outer guide groove, respectively, so that the waterproof assembly 4 can be switched to an initial state or a waterproof state by adjusting the positions of the inner baffle 41 and the outer baffle 42. The inner guide groove and the outer guide groove are arranged so that the inner baffle 41 and the outer baffle 42 can move along their respective predetermined trajectories, and the movements of the inner baffle 41 and the outer baffle 42 do not interfere with each other. When the waterproof assembly 4 is in the initial state, most areas of the inner baffle 41 and the outer baffle 42 overlap, and the ends of the inner baffle 41 and the outer baffle 42 are spaced apart, so as to form upper and lower openings of the avoidance channel, thereby allowing airflow to flow in and out normally and reducing airflow obstruction.

[0062] To enhance the waterproofing and avoidance effects of the waterproof assembly 4, multiple inner baffles 41 are independently mounted within the inner guide groove; and / or multiple outer baffles 42 are independently mounted within the outer guide groove. This arrangement allows the waterproof assembly 4 to switch between multiple waterproof states.

[0063] like Figures 5 to 10 As shown, to provide inner and outer guide grooves, the guide assembly 3 in this embodiment includes an annular frame 33 and a guide rail component 34. The annular frame 33 has a mounting groove that surrounds the heat exchanger 2, and the guide rail component 34 is disposed within the mounting groove. The mounting groove has an inner groove wall and an outer groove wall that are disposed opposite each other. The inner groove wall and the outer groove wall both surround the heat exchanger 2. The inner guide groove is formed between the guide rail component 34 and the inner groove wall, and the outer guide groove is formed between the guide rail component 34 and the outer groove wall. This arrangement prevents the inner and outer guide grooves from interfering with each other, effectively utilizes space, and reduces production costs.

[0064] In order to drive the waterproof component 4 to move on the guide component 3, the waterproof component 4 includes a baffle component 47, which is movably mounted on the guide component 3. The waterproof device also includes a driving component 7, which is drivingly connected to the baffle component 47 to drive the baffle component 47 to move along the extension direction of the guide component 3, so that the waterproof component 4 moves to an initial state or a waterproof state.

[0065] Furthermore, since there can be multiple baffle components 47, each baffle component 47 can be movably mounted on the guide assembly 3; in order to drive each baffle component 47 to move independently without interfering with each other, there are multiple drive components 7, and multiple drive components 7 are arranged one-to-one corresponding to multiple baffle components 47 to drive each baffle component 47 to move independently, so that each baffle component 47 can move to a different position.

[0066] Preferably, the drive assembly 7 in this embodiment includes a drive motor and a transmission component, the drive motor is connected to the transmission component, and the transmission component is in transmission connection with the baffle component 47, so that the drive motor drives the baffle component 47 to move through the transmission component. Specifically, the drive motor has a drive body and an output shaft, and the output shaft is connected to the transmission component, so that the movement of the output shaft drives the transmission component to drive the baffle component 47 to move.

[0067] Among them, in order to install the drive assembly 7 and prevent the drive assembly 7 from being exposed to the external environment, the waterproof device also includes a mounting base 10, which is installed on the side wall of the electrical box 1. The mounting base 10 includes a mounting protrusion 11 and an avoidance cavity 12. The inner wall of the avoidance cavity 12 is arranged around the heat exchanger 2 so that the heat exchanger 2 passes through the avoidance cavity 12; the interior of the mounting protrusion 11 has a mounting cavity, and the drive motor is arranged in the mounting cavity. Specifically, the drive body is arranged in the mounting cavity, and the side of the mounting protrusion 11 facing the baffle component 47 is provided with an opening, and the output shaft of the drive motor extends from this opening to connect with the transmission component. Such a setting facilitates the disassembly of the drive motor while protecting the drive motor, thereby extending the service life of the drive assembly 7.

[0068] Specifically, in order to drive the baffle component 47 to move through the drive assembly 7, the transmission component in this embodiment includes a transmission chain 71 and a transmission sprocket 72, and the transmission chain 71 is connected to the baffle component 47; the output shaft of the drive motor is connected to the transmission sprocket 72, and the transmission sprocket 72 is connected to the transmission chain 71, so that the drive motor drives the transmission chain 71 to rotate.

[0069] like Figure 13 and Figure 14 As shown, the baffle component 47 in this embodiment moves in the V direction driven by the transmission chain 71.

[0070] Furthermore, in order to realize different states of the waterproof component 4, the guide component 3 includes a guide rail component 34, a plurality of baffle components 47, a plurality of transmission chains 71 and a plurality of transmission sprockets 72, the plurality of transmission chains 71 are arranged in a one-to-one correspondence with the plurality of transmission sprockets 72, and the plurality of baffle components 47 are arranged in a one-to-one correspondence with the plurality of transmission chains 71. The specific implementation of the guide rail component 34 in this embodiment is as follows:

[0071] A first specific structural form of the guide assembly 3 is as follows: two guide rail components 34 are arranged around the heat exchanger 2, and each guide rail component 34 is provided with at least one transmission chain 71. This arrangement makes the guide rail components 34 independent and non-interfering with each other, thereby achieving independent driving of the multiple baffle components 47.

[0072] The second specific structural form of the guide assembly 3 is: Figures 8 to 10As shown, the guide rail component 34 includes an inner guide rail portion 31 and an outer guide rail portion 32. The inner guide rail portion 31 and the outer guide rail portion 32 are both arranged around the heat exchanger 2. The inner guide rail portion 31 is located on the inner side of the outer guide rail portion 32. A transmission chain 71 is respectively arranged around the outer side of the inner guide rail portion 31 and the outer guide rail portion 32. The inner guide rail portion 31 is arranged to protrude from the outer guide rail portion 32 in a direction away from the electrical box 1, so that the transmission sprocket 72 arranged around the inner guide rail portion 31 is connected to the corresponding transmission sprocket 72. This arrangement not only ensures that each transmission sprocket 72 can be driven and connected to each transmission chain 71 in a one-to-one correspondence, but also improves space utilization.

[0073] First embodiment:

[0074] like Figure 16 As shown, the guide assembly 3 extends along a circular track, and the guide assembly 3 includes an inner guide portion and an outer guide portion. The inner guide portion and the outer guide portion are both arranged around the heat exchanger 2, and the outer guide portion is located outside the inner guide portion. The waterproof state includes a first waterproof state.

[0075] Specifically, waterproof assembly 4 includes a first inner baffle 411 and a first outer baffle 421. The first inner baffle 411 cooperates with the inner guide portion to move along the inner guide portion, while the first outer baffle 421 cooperates with the outer guide portion to move along the outer guide portion. When waterproof assembly 4 is in the first waterproof state, the upper ends of the first inner baffle 411 and the upper ends of the first outer baffle 421 overlap in the radial direction of guide assembly 3, while the lower ends of the first inner baffle 411 and the lower ends of the first outer baffle 421 are spaced apart in the circumferential direction of guide assembly 3 to block liquid above heat exchanger 2. When waterproof assembly 4 is in the first waterproof state, water is prevented from flowing from above heat exchanger 2 into the gap between heat exchanger 2 and electrical box 1.

[0076] Furthermore, in order to reduce the interference with the airflow flowing on the side of the electrical box 1, the waterproof component 4 also includes a second inner baffle 412 and a second outer baffle 422. The second inner baffle 412 cooperates with the inner guide portion to move along the inner guide portion, and the second outer baffle 422 cooperates with the outer guide portion to move along the outer guide portion.

[0077] When waterproof assembly 4 is in the first waterproof state, second inner baffle 412 and second outer baffle 422 are located on opposite sides of heat exchanger 2, with the upper ends of second inner baffle 412 and second outer baffle 422 spaced apart along the circumferential direction of guide assembly 3. The lower ends of second inner baffle 412 and second outer baffle 422 are spaced apart along the circumferential direction of guide assembly 3 to form an air inlet opening for the avoidance channel. This arrangement allows airflow from the sides of electrical box 1 to flow from the air inlet opening into the avoidance channel.

[0078] Since the airflow circulating on the side of the electrical box 1 flows vertically from the bottom to the top, the water flow may be drawn into the gap between the heat exchanger 2 and the electrical box 1 from the bottom of the heat exchanger 2 by the airflow. The guide assembly 3 extends along a circular trajectory, and the waterproof assembly 4 includes multiple baffle components 47. The waterproof state also includes a second waterproof state; when the waterproof device is in the second waterproof state, multiple baffle components 47 are arranged around the heat exchanger 2, and the ends of two adjacent baffle components 47 are overlapped along the radial direction of the guide assembly 3.

[0079] Specifically, if Figure 17 As shown, the guide assembly 3 extends along a circular track, and the waterproof state also includes a second waterproof state; the guide assembly 3 includes an inner guide portion and an outer guide portion, both of which are arranged around the heat exchanger 2, and the outer guide portion is located outside the inner guide portion.

[0080] Furthermore, in order to fully block the gap between the heat exchanger 2 and the electrical box 1, the waterproof component 4 includes a first inner baffle 411, a first outer baffle 421, a second inner baffle 412 and a second outer baffle 422. The first inner baffle 411 and the second inner baffle 412 can be slidably installed on the inner guide part, and the first outer baffle 421 and the second outer baffle 422 can be slidably installed on the outer guide part.

[0081] In which, when the waterproof device is in the second waterproof state, the upper end of the first inner baffle 411 and the upper end of the first outer baffle 421 are overlapped along the radial direction of the guide assembly 3, the lower end of the first inner baffle 411 and the upper end of the second outer baffle 422 are overlapped along the radial direction of the guide assembly 3, the lower end of the second outer baffle 422 and the lower end of the second inner baffle 412 are overlapped along the radial direction of the guide assembly 3, and the lower end of the first outer baffle 421 and the upper end of the second inner baffle 412 are overlapped along the radial direction of the guide assembly 3.

[0082] In order to achieve the separate driving of the first inner baffle 411, the first outer baffle 421, the second inner baffle 412 and the second outer baffle 422, the inner guide rail portion 31 includes a first inner guide rail 311 and a second inner guide rail 312, and the two ends of the first inner guide rail 311 are connected to the two ends of the second inner guide rail 312; the outer guide rail portion 32 includes a first outer guide rail 321 and a second outer guide rail 322, and the two ends of the first outer guide rail 321 are connected to the two ends of the second outer guide rail 322.

[0083] Among them, the first inner baffle 411 is connected to the transmission chain 71 set on the first inner guide rail 311, and moves along the extension direction of the first inner guide rail 311; the second inner baffle 412 is connected to the transmission chain 71 set on the second inner guide rail 312, and moves along the extension direction of the second inner guide rail 312; the first outer baffle 421 is connected to the transmission chain 71 set on the second outer guide rail 322, and moves along the extension direction of the second outer guide rail 322; the second outer baffle 422 is connected to the transmission chain 71 set on the first outer guide rail 321, and moves along the extension direction of the first outer guide rail 321.

[0084] Since the two ends of the first inner guide rail 311 are butted against the two ends of the second inner guide rail 312, and the first inner guide rail 311 and the first outer guide rail 321 are a whole, and the second inner guide rail 312 and the second outer guide rail 322 are a whole, when the waterproof component 4 is in the second waterproof state, in order to achieve the overlapping arrangement of the ends of the two adjacent baffle components 47 along the radial direction of the guide component 3, the waterproof component also includes two first extended baffles 43 and two second extended baffles 44, each first extended baffle 43 is seamlessly connected to the two ends of the inner baffle 41, and the side of the first extended baffle 43 close to the inner guide rail portion 31 is higher than the end face of the inner guide rail portion 31, and fits with the end face of the inner guide rail portion 31; each second extended baffle 44 is seamlessly connected to the two ends of the outer baffle 42, and the side of the second extended baffle 44 close to the outer guide rail portion 32 is higher than the end face of the outer guide rail portion 32, and fits with the end face of the outer guide rail portion 32. When the waterproof assembly 4 is in the second waterproof state, the second extended baffle 44 moves to the outside of the first extended baffle 43 so that the ends of two adjacent baffle components 47 are overlapped in the radial direction of the guide assembly 3 .

[0085] like Figure 15 As shown, the waterproof assembly 4 includes two groups of baffle parts 47, each group of baffle parts 47 includes an inner baffle 41 and an outer baffle 42, and the inner baffle 41 is located on the side of the outer baffle 42 close to the heat exchanger 2; when the waterproof device is in the initial state, the lower ends of the two groups of baffle parts 47 are spaced apart to form an air inlet opening of the avoidance channel, and the upper ends of the two groups of baffle parts 47 are spaced apart to form an air outlet opening of the avoidance channel, so that the airflow on the side of the electrical box 1 enters the avoidance channel from the air inlet opening and then flows out from the air outlet opening, thereby reducing the impact on the airflow circulation and reducing the attenuation of the wind volume.

[0086] In the first embodiment, the waterproof component 4 is always located outside the electrical box 1 , and the waterproof component 4 moves around the circumferential direction of the heat exchanger 2 .

[0087] Second embodiment:

[0088] The electrical box 1 includes a accommodating cavity and an extension opening, which is arranged on the side wall of the electrical box 1 and surrounds the heat exchanger 2; the guide assembly 3 is arranged in the accommodating cavity, and the guide assembly 3 extends along a straight track and is perpendicular to the side wall of the electrical box 1; the waterproof assembly 4 includes a baffle component 47, and a baffle component 47 is provided on the upper side and / or lower side of the heat exchanger 2. The baffle component 47 is movably installed on the guide assembly 3 along the extension direction of the guide assembly 3, so that the baffle component 47 can be extended or retracted through the extension opening to block or avoid the heat exchanger 2; wherein, when the waterproof assembly 4 is in the initial state, the waterproof assembly 4 is located in the accommodating cavity.

[0089] Specifically, the waterproof state includes a first waterproof state; the guide assembly 3 includes a first guide groove and a second guide groove; the waterproof assembly 4 includes a first baffle, one end of the first baffle is inserted in the first guide groove, and the other end of the first baffle is inserted in the second guide groove, and the first baffle is arranged on the upper side of the heat exchanger 2; when the waterproof assembly 4 is in the first waterproof state, the first baffle extends through the extension opening and blocks the upper side of the heat exchanger 2.

[0090] Furthermore, the waterproof state includes a second waterproof state; the guide assembly 3 includes a third guide groove and a fourth guide groove; the waterproof assembly 4 includes a second baffle, one end of the second baffle is inserted in the third guide groove, and the other end of the second baffle is inserted in the fourth guide groove, and the second baffle is arranged on other sides except the upper side of the heat exchanger 2; when the waterproof assembly 4 is in the second waterproof position, the first baffle and the second baffle both extend through the extension opening and surround the heat exchanger 2.

[0091] In the second embodiment, the waterproof component 4 is located inside the electrical box 1 in the initial state. When in the waterproof state, the waterproof component 4 extends from the inside of the electrical box 1 to shield the heat exchanger 2 .

[0092] like Figure 11 As shown, in order to reduce the impact of the waterproof component 4 on the airflow on the side of the electrical box 1, the waterproof component 4 also includes a baffle component 47, which is provided with multiple ventilation holes 45. The multiple ventilation holes 45 are arranged in sequence along the extension direction of the baffle component 47.

[0093] Further, if Figure 12 As shown, in order to allow air flow to pass through while preventing water flow from passing through, the ventilation hole 45 is a strip hole, and the ventilation hole 45 extends along the width direction of the baffle part 47; a first angle is formed between the depth direction of the ventilation hole 45 and the thickness direction of the baffle part 47, and the first angle is greater than 0° and less than 90°.

[0094] Preferably, if Figure 15As shown, in order to control the start and stop of the driving component 7, the waterproof state includes a first waterproof state and a second waterproof state; the waterproof device also includes a sensing component 8, which is arranged on one side of the waterproof component and is communicatively connected to the driving component 7, including a first sensing component 81, a second sensing component 83 and a third sensing component 82.

[0095] Among them, the first sensing component 81 is located above the heat exchanger 2 to detect whether there are water droplets dripping above the heat exchanger 2; the second sensing component 83 is located on the horizontal side of the heat exchanger 2 to detect whether there are water droplets on the side of the heat exchanger 2; the third sensing component 82 is located below the heat exchanger 2 to detect whether there are water droplets below the heat exchanger 2.

[0096] like Figure 1 As shown, the present invention also provides an air-conditioning outdoor unit, which includes an electrical box 1. The air-conditioning outdoor unit also includes the above-mentioned waterproof device and a condenser 9. The waterproof device is installed on the side wall of the electrical box 1; the condenser 9 includes a mounting shell, the mounting shell has a ventilation cavity 91, the heat exchanger 2 is arranged in the ventilation cavity 91, and the electrical box 1 is arranged on the outside of the mounting shell.

[0097] like Figure 20 As shown, the present invention also provides a waterproof control method, which is applicable to the above-mentioned waterproof device. The waterproof control method also includes starting the waterproof device and controlling the waterproof component 4 of the waterproof device to be in the initial state of the waterproof device; detecting whether there are water droplets on the circumferential outer side of the heat exchanger 2, so as to control the waterproof component 4 to be in the waterproof state of the waterproof device according to the detection result.

[0098] Furthermore, the waterproof control method also includes controlling the waterproof component 4 of the waterproof device to be in an initial state when it is detected that there are no water droplets on the circumferential outer side of the heat exchanger 2; otherwise, controlling the waterproof component 4 to block the upper side of the heat exchanger 2 and making the waterproof component 4 avoid the bottom of the heat exchanger 2 so that the waterproof component 4 is in a first waterproof state.

[0099] Specifically, after controlling the waterproof component 4 to be in the first waterproof state, the waterproof control method also includes continuing to detect whether there are water droplets on the circumferential outer side of the heat exchanger 2; when it is detected that there are no water droplets on the circumferential outer side of the heat exchanger 2, controlling the waterproof component 4 to be in the initial state; otherwise, continuing to detect whether there are water droplets on the lower side of the heat exchanger 2; when there are water droplets on the lower side of the heat exchanger 2, controlling the waterproof component 4 to cover both the upper and lower sides of the heat exchanger 2, so that the waterproof device is in the second waterproof state.

[0100] When the waterproof component 4 is in the initial state: in this state, the waterproof component 4 has little effect on the airflow on the side of the electrical box 1 and the airflow can dissipate heat to the heat exchanger 2, and the applicable environment is an external environment without rain.

[0101] When the waterproof assembly 4 is in the first waterproof state: In this state, the waterproof assembly 4 has a certain slight impact on the airflow on the side of the electrical box 1, but the airflow entering the escape channel can also escape through the vents 45, and the airflow can dissipate heat to the heat exchanger 2. The applicable environment is rainy, but the water flow is not affected by the airflow and rolled up.

[0102] When the waterproof component 4 is in the second waterproof state: in this state, the waterproof component 4 has a certain slight impact on the airflow on the side of the electrical box 1. The airflow passes through both sides of the baffle component 47 and does not enter the escape channel. The applicable environment is rainy and the water flow is affected by the airflow and rolls up.

[0103] like Figure 20 As shown, the specific implementation of the waterproof control method in this embodiment is as follows:

[0104] 1) When the waterproof component 4 is started, it is in the initial state. In this state, the waterproof component 4 has little effect on the airflow on the side of the electrical box 1 and the airflow can dissipate heat for the heat exchanger 2.

[0105] 2) Determine whether the first sensing component 81, the second sensing component 83 or the third sensing component 82 is triggered. If not, the waterproof component 4 is in the initial state; if yes, the external environment is in a rainy state, so the waterproof component 4 switches to the first waterproof state.

[0106] 3) Determine whether the first sensing component 81, the second sensing component 83 or the third sensing component 82 is triggered. If not, the waterproof component 4 switches to the initial state; if yes, the external environment is in a rainy state at this time, and proceed to the next step of determination.

[0107] 4) Determine whether the third sensing component 82 is triggered. If yes, the external environment is in a rainy state and the water flow is rolled up by the air flow, and the waterproof component 4 switches to the second waterproof state; if no, the waterproof component 4 switches to the first waterproof state.

[0108] 5) After the waterproof component 4 is in the second waterproof state, it enters a stage of three simultaneous judgments, and the effects achieved are: first aspect: when the first sensing component 81, the second sensing component 83 or the third sensing component 82 is not triggered, the external environment is in a non-raining state, and the waterproof component 4 switches to the initial state; second aspect: when the first sensing component 81 or the second sensing component 83 is triggered, but the third sensing component 82 is not triggered, the external environment is in a rainy state but the water flow is not affected by the airflow and rolled up, and the waterproof component switches to the first waterproof state; third aspect: when the first sensing component 81, the second sensing component 83 and the third sensing component 82 are triggered, the external environment is in a rainy state and the water flow is affected by the airflow and rolled up, and the waterproof component 4 switches to the second waterproof state.

[0109] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0110] The air conditioner outdoor unit of the present invention includes a waterproof device. The waterproof control method of the present invention is applicable to the waterproof device. The waterproof device of the present invention includes a guide assembly 3 and a waterproof assembly 4. The guide assembly 3 is mounted on the electrical box 1 and extends along a predetermined path. At least a portion of the waterproof assembly 4 is mounted on the guide assembly 3 and is movable along the extension direction of the guide assembly 3. The guide assembly 3 and the waterproof assembly 4 are arranged so that the waterproof assembly 4 can switch between an initial state and a waterproof state along the predetermined path of the guide assembly 3. When the waterproof assembly 4 is in the waterproof state, at least a portion of the waterproof assembly 4 blocks the upper side and / or lower side of the heat exchanger 2 to block the gap between the heat exchanger 2 and the electrical box 1. When the waterproof assembly 4 is in the initial state, the waterproof assembly 4 forms an escape channel for avoiding airflow to the side of the electrical box 1, so that airflow to the side of the electrical box 1 passes through the escape channel and the waterproof assembly 4. This solves the problem of water easily entering the electrical box of the air conditioner outdoor unit through the heat dissipation opening in the prior art, thereby extending the service life of the electrical box and the air conditioner outdoor unit.
