Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, especially to an air duct assembly of an electric control box and an air conditioner. BACKGROUND

[0002] Air conditioner is an indispensable electrical equipment in people's daily life, which has various structural forms. The outdoor unit of the air conditioner is often provided with an electric control box. The heat dissipation inside the electric control box is often achieved by arranging heat dissipation fins, which results in relatively low heat dissipation efficiency. Therefore, the prior art proposes to arrange an air duct in the electric control box to utilize the flow of air to make the high-temperature gas in the electric control box flow out of the electric control box to dissipate heat.

[0003] However, for individual large outdoor units, such as the outdoor unit of an energy storage air conditioner, they are often arranged outdoors. On the one hand, they are subjected to the impact of rainwater, which can easily cause rainwater to enter the electric control box from the air duct, causing safety hazards. On the other hand, the entire electric control box often needs to be moved to facilitate the daily maintenance and repair of other parts of the outdoor unit. If the existing electric control box air duct structure is directly used, it will often affect the movement of the entire electric control box. SUMMARY

[0004] Therefore, the present application aims to provide an air duct assembly of an electric control box and an air conditioner to solve the problems in the prior art that rainwater easily enters the electric control box from the air duct and the conventional air duct structure easily affects the movement of the entire electric control box.

[0005] To achieve the above-mentioned purpose, the technical solution of the present application is as follows:

[0006] An air duct assembly of an electric control box comprises a first air duct and a second air duct. The first air duct and the second air duct can be detached and separated. The first inlet of the first air duct is connected to the electric control box. The first outlet of the first air duct can be in communication with the second inlet of the second air duct. The lowest point of the second inlet of the second air duct is higher than the highest point of the second outlet of the second air duct. When the entire electric control box needs to be moved, the entire electric control box can be directly moved, and at the same time, the first air duct and the second air duct are separated, which will not interfere with the movement of the electric control box, facilitating the daily maintenance and repair of the outdoor unit. In addition, the second outlet of the second air duct is the overall air outlet of the air duct assembly, and the highest point of the second outlet is lower than the lowest point of the second inlet. Therefore, after the rainwater enters the air duct assembly from the second outlet, it will not continue to flow to the first air duct, and will not flow into the electric control box, which can effectively prevent rainwater from easily entering the electric control box from the air duct.

[0007] Further, the electric control box is provided with an air outlet, the first inlet is communicated with the air outlet, and the second outlet is arranged at the air suction side of the fan part of the air conditioner outdoor unit. Thus, with rotation of the fan part, negative pressure is formed at the second outlet, and the high-temperature gas in the electric control box can be extracted from the air duct assembly.

[0008] Further, the second air duct comprises a first pipe section, a second pipe section and a third pipe section communicated in sequence, the second pipe section extends downwardly and obliquely, so that the lowest point of the second inlet is higher than the highest point of the second outlet, thereby effectively avoiding rainwater from entering the electric control box from the air duct.

[0009] Further, the first pipe section is parallel to the third pipe section, and the included angle B between the first pipe section and the second pipe section is 90-150°, which facilitates production and processing of the second air duct and enables the gas to flow more smoothly in the second air duct.

[0010] Further, the second outlet is arranged below the fan part, the end face of the second outlet is inclined upwardly, and the included angle C between the end face of the second outlet and the lower pipe wall of the third pipe section is 45-75°, so that the negative pressure generated by the fan part can directly act on the second outlet, and the gas can flow more smoothly to the fan part.

[0011] Further, the air duct assembly comprises a support, the support is connected with the frame of the air conditioner outdoor unit or the shell assembly of the air conditioner outdoor unit, and the second air duct is connected with the support, so that after the first air duct is separated from the second air duct, the support can provide fixed support for the second air duct, thereby avoiding deviation of the second air duct and ensuring that the first air duct can be communicated with the second air duct again.

[0012] Further, the support is provided with a communication port, one side of the communication port is communicated with the second inlet, and the other side of the communication port is communicated with the first outlet, and the first air duct can be detached from the communication port. Thus, on the basis that the second air duct is fixed and the first air duct moves with the electric control box, the first outlet can be aligned and attached to the communication port, thereby ensuring communication and detachment of the first air duct from the second air duct.

[0013] Further, the support is provided with a communication port, the second inlet penetrates through the communication port, and the first outlet and the second inlet can be detached from each other. Thus, on the basis that the second air duct is fixed and the first air duct moves with the electric control box, the first outlet can be aligned and attached to the second inlet, thereby ensuring communication and detachment of the first air duct from the second air duct.

[0014] Further, the first outlet is provided with a sealing ring, and the first outlet is sealed with the sealing ring and the communication port or the second inlet, so as to improve the air tightness of the air duct assembly.

[0015] The application discloses an air conditioner, which comprises an electric control box, a fan part and an air duct assembly of the electric control box.

[0016] Compared with the prior art, the air conditioner and the air duct assembly of the electric control box have the following advantages:

[0017] The air conditioner and the air duct assembly of the electric control box can directly move the whole electric control box when the whole electric control box needs to be moved, and meanwhile, the first air duct and the second air duct are separated, so that the movement of the electric control box is not interfered, and daily maintenance and repair of the outdoor unit are facilitated; in addition, the second outlet of the second air duct is the whole air outlet of the air duct assembly, and the highest point of the second outlet is lower than the lowest point of the second inlet, so that rainwater entering the air duct assembly from the second outlet cannot continue to flow to the first air duct, and cannot flow into the electric control box, and rainwater can be effectively prevented from easily entering the electric control box from the air duct.

[0026] The application concepts of the present disclosure will be described below using terms that are commonly used by those skilled in the art to convey the substance of their work to other skilled artisans in the art. However, these application concepts can be embodied in many different forms, and therefore should not be considered limited to the embodiments described herein.

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0028] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0029] In the prior art, an air duct is often arranged in the electric control box of the air conditioner, and the high-temperature gas in the electric control box is caused to flow out from the inside of the electric control box by the flow of the air current to perform heat dissipation and cooling. However, for individual large outdoor units, such as the outdoor unit of an energy storage air conditioner, which are often arranged outdoors, on the one hand, they are prone to being impacted by rainwater, which can cause the rainwater to enter the inside of the electric control box from the air duct, thereby causing a safety hazard, and on the other hand, the entire electric control box often needs to be moved to facilitate the daily inspection and maintenance of other components of the outdoor unit. If the existing arrangement of the air duct structure of the electric control box is directly used, it will often affect the movement of the entire electric control box.

[0030] To solve the problems in the prior art that rainwater is prone to entering the inside of the electric control box from the air duct and the conventional air duct structure is prone to affecting the movement of the entire electric control box, the present embodiment proposes an air duct assembly of an electric control box, as shown in Figures 1-5 The air duct assembly 2 includes a first air duct 21 and a second air duct 22, the first air duct 21 and the second air duct 22 can be detached and separated, a first inlet 211 of the first air duct 21 is connected with the electric control box 1, a first outlet 212 of the first air duct 21 can be in communication with a second inlet 221 of the second air duct 22, and the lowest point of the second inlet 221 of the second air duct 22 is higher than the highest point of a second outlet 222 of the second air duct 22.

[0031] Therefore, by arranging the air duct assembly 2 in the electric control box 1, when the entire electric control box 1 needs to be moved, the entire electric control box 1 can be directly moved, and at the same time, the first air duct 21 and the second air duct 22 are separated, which will not interfere with the movement of the electric control box 1, thereby facilitating the daily inspection and maintenance of the outdoor unit. In addition, the second outlet 222 of the second air duct 22 is the overall air outlet of the air duct assembly 2, and the highest point thereof is lower than the lowest point of the second inlet 221, so that after the rainwater enters the air duct assembly 2 from the second outlet 222, it will not continue to flow to the first air duct 21, and will not flow into the inside of the electric control box 1, thereby effectively avoiding the rainwater from easily entering the inside of the electric control box from the air duct.

[0032] For the gas flow, the gas in the electric control box 1 can be caused to flow out by setting an additional fan in the air duct or the electric control box 1, or the fan part 3 of the outdoor unit can be used to form a negative pressure at the second outlet 222 so that the gas in the electric control box 1 flows out. As a preferred solution of the present application, the air outlet 13 is arranged on the side wall of the electric control box 1 close to the fan part 3, the first inlet 211 of the first air duct 21 communicates with the air outlet 13, the first air duct 21 extends towards the fan part 3 and communicates with the second inlet 221 of the second air duct 22, and the second outlet 222 of the second air duct 22 is arranged on the air suction side of the fan part 3. Thus, with the rotation of the fan part 3, a negative pressure is formed at the second outlet 222, and the high-temperature gas in the electric control box 1 can be extracted from the air duct assembly 2.

[0033] The second air duct 22 comprises a first pipe section 223, a second pipe section 224 and a third pipe section 225 which communicate in sequence, and the second pipe section 224 extends downwardly obliquely so that the lowest point of the second inlet 221 is higher than the highest point of the second outlet 222, thereby effectively preventing rainwater from entering the electric control box from the air duct.

[0034] The first pipe section 223 is parallel to the third pipe section 225, and the included angle B between the first pipe section 223 and the second pipe section 224 is 90°-150°, which facilitates the production and processing of the second air duct 22 and enables the gas to flow more smoothly in the second air duct 22.

[0035] For a conventional large air conditioner outdoor unit, the fan part 3 is usually arranged at the top of the outdoor unit, the second outlet 222 is arranged below the fan part 3, the end face of the second outlet 222 is inclined upwardly, and the included angle C between the end face of the second outlet 222 and the lower pipe wall of the third pipe section 225 is 45°-75°, so that the negative pressure generated by the fan part 3 can directly act on the second outlet 222 and the gas can flow more smoothly to the fan part 3.

[0036] Correspondingly, the air outlet 13 is arranged on the top plate of the electric control box 1, and the first air duct 21 extends upwardly and towards the second inlet 221 of the second air duct 22. In the drawings of the present application, the first air duct 21 extends in a bent manner, and of course, according to the position of the second inlet 221, the first air duct 21 can also extend in other forms.

[0037] As a preferred solution of the present application, the first pipe section 223 and the third pipe section 225 are both arranged horizontally, or the third pipe section 225 is arranged slightly obliquely downwardly so that the rainwater entering the third pipe section 225 can flow out, thereby avoiding the accumulation of rainwater in the third pipe section 225 as much as possible. Correspondingly, the first air duct 21 extends in a bent manner by about 90°, i.e. the first air duct 21 first extends upwardly and then extends horizontally until it communicates with the second inlet 221.

[0038] The air duct assembly 2 comprises a support 23 connected with the frame 4 or the shell assembly, and the second air duct 22 is connected with the support 23, so that the support 23 can provide fixed support for the second air duct 22 after the first air duct 21 is separated from the second air duct 22, avoiding deviation of the second air duct 22 and ensuring that the first air duct 21 can be communicated with the second air duct 22 again.

[0039] Specifically, for the communication and disassembly of the first air duct 21 and the second air duct 22, at least two forms can be provided:

[0040] Form one, the support 23 is provided with a communication port 231, one side of the communication port 231 is communicated with the second inlet 221 of the second air duct 22, and the other side is communicated with the first outlet 212 of the first air duct 21, and the first air duct 21 can be disassembled from the communication port 231.

[0041] Form two, the support 23 is provided with a communication port 231, the second inlet 221 of the second air duct 22 penetrates the communication port 231, and the first outlet 212 of the first air duct 21 and the second inlet 221 of the second air duct 22 can be disassembled.

[0042] Since the second air duct 22 is fixed, the first air duct 21 moves with the electric control box 1, in order to facilitate operation, on the basis of form one or form two, it can be considered that the first outlet 212 can be aligned and attached with the communication port 231, or the first outlet 212 is aligned and attached with the second inlet 221. At the same time, considering the sealing problem, the first outlet 212 is provided with a sealing ring 24, and the first outlet 212 is sealed with the communication port 231 or the second inlet 221 through the sealing ring 24, so as to improve the air tightness of the air duct assembly 2. Correspondingly, the sealing ring 24 can also be arranged on the communication port 231 or the second inlet 221, which will not be described in detail. The sealing ring 24 is a rubber ring or a cotton sealing ring.

[0043] For the movement of the electric control box 1, as a preferred scheme of the present application, one side of the electric control box 1 is provided with a hinge 14, and the electric control box 1 is connected with the frame 4 or the shell of the outdoor unit through the hinge 14, so that the whole electric control box 1 can rotate along the hinge shaft, facilitating people to maintain the interior of the outdoor unit. When the electric control box 1 rotates along the hinge shaft, the first air duct 21 can directly rotate with the electric control box 1 and separate from the second air duct 22.

[0044] In addition to the air duct assembly 2, the electric control box 1 is also provided with a heat dissipation fin 11 and a heat dissipation fan 12 to dissipate heat for the control panel. Since the technology of dissipating heat through fins for the electric control box 1 is relatively common, the present application will not be described in detail.

[0045] In the present application, for any air conditioner, including the electric control box 1, fan part 3, the air duct assembly 2 described in the embodiment, one end of the air duct assembly 2 is connected with the electric control box 1, and the other end extends to the air suction side of the fan part 3. Of course, the electric control box 1 can be in a fixed form, or the entire electric control box can be in a movable form.

[0046] In addition, the air conditioner also includes the conventional components of the air conditioner outdoor unit, such as heat exchange coil, compressor, etc.; similarly, the air conditioner also includes the air conditioner indoor unit and related components; since it is prior art, it is not described here.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
