Referring to fig. 1 to 3, an embodiment of the present invention provides an outdoor unit 100 of an air conditioner, including: a housing 200, the housing 200 having a duct 210 communicating with an external space; the fan 300, the fan 300 is set in the air duct 210; the electronic control box 400 is mounted on the housing 200, the electronic control box 400 has a containing cavity 410, and an air inlet 420 and an air outlet 430 communicated with the containing cavity 410, the air inlet 420 and the air outlet 430 are both disposed in the air duct 210, and the air inlet 420 is disposed on one side of the air outlet 430 far away from the fan 300.

It should be noted that the electrical control box 400 provided in the embodiment of the present application is particularly suitable for the top-outlet type outdoor unit 100 of the air conditioner. Accordingly, the housing 200 is generally cylindrical and hollow therein, i.e., the air duct 210, for mounting the fan 300 and the compressor. An opening is formed in at least one bottom surface of the housing 200, the fan 300 is started to drive airflow to flow along the air duct 210 and flow out of the opening, the opening is the air outlet 230, and the fan 300 is generally installed on one side of the housing 200 close to the air outlet 230; the other bottom surface and/or side surface of the case 200 is provided with an opening for sucking air from the external space, i.e., the air inlet 220. Air from the external space generally flows into the interior of the housing 200 through the air inlet 220 and out of the air outlet 230 through the air duct 210.

It should be noted that the extending direction of the central axis of the fan 300 is parallel to the first direction F1, and the direction of the airflow passing through the fan 300 is the first direction F1.

It should be noted that the electronic control box 400 may be integrally formed, or may be formed by enclosing a plurality of side plates; and a receiving cavity 410 is formed in the electronic control box 400. The housing 410 is generally configured to house an electronic control module 411, a communication module 412, etc., which is typically in communication with the fan 300 and the compressor, etc., to control and regulate the fan 300 and the compressor, etc.

The fan 300 draws an airflow from the external space into the wind tunnel 210 and flows from one end of the wind tunnel 210 far from the fan 300 to the other end. By arranging the air inlet 420 and the air outlet 430 of the electronic control box 400 in the air duct 210, the air outlet 430 is arranged closer to the fan 300; the airflow in the air duct 210 is driven to enter the accommodating cavity 410 from the air inlet 420, so that the airflow entering the accommodating cavity 410 can be increased, and the accommodating cavity 410 is pressurized to accelerate the airflow to flow out of the electronic control box 400; the air outlet 430 is affected by the fast flowing air flow, and the air outlet 430 is in a negative pressure environment, so that the air in the accommodating cavity 410 can be sucked out, and the air flow can be further accelerated to flow out of the electronic control box 400. Thus, the air flow passing through the accommodating cavity 410 can be increased, and the heat dissipation effect of the electronic control box 400 can be improved.

Preferably, the air inlet 220 and the air outlet 230 of the housing 200 are oppositely disposed on both bottom surfaces of the housing 200.

By arranging the air inlet 220 and the air outlet 230 opposite to each other, the air duct 210 can be made to be approximately cylindrical, thereby reducing the on-way loss of the air flow in the air duct 210 and improving the air volume of the outdoor unit 100. And the air flow direction in the cylindrical air duct 210 is smoother, the air flow can more smoothly enter the accommodating cavity 410 from the air inlet 420, and the air flow passing through the accommodating cavity 410 is improved.

Further, in other embodiments, the air inlet 220 of the housing 200 may also be disposed on a sidewall of the housing 200; in particular, the air inlet 220 on the sidewall may be composed of a plurality of holes arranged in an array, which is not limited herein.

In some embodiments, the electronic control box 400 is provided with a water baffle 440 at the air inlet 420.

It is understood that the outdoor unit 100 of the present invention may be of a top-discharge type, which is generally disposed in an outdoor environment. Rains often occur outdoors, so that raindrops enter the outdoor unit 100 of the air conditioner; and the air conditioner outdoor unit 100 into which microorganisms, impurities, and the like easily enter. The operation efficiency, even the operation safety of the air conditioner outdoor unit 100 is affected to some extent.

The water baffle 440 is arranged at the air inlet 420, so that the probability of water drops entering the accommodating cavity 410 can be reduced, and the influence of water on the normal operation of the components such as the electronic control module 411, the communication module 412 and the like in the electronic control box 400 can be further effectively reduced. The operation efficiency and the use reliability of the electronic control box 400 are improved.

Specifically, the extending direction of the water guard plate 440 is perpendicular to the first direction F1.

In some embodiments, the electrical control box 400 is provided with two water baffles 440 arranged along the first direction F1, and orthographic projections of the two water baffles 440 in a plane perpendicular to the first direction F1 at least partially overlap.

It should be noted that, when the outdoor environment rains, a part of the raindrops passes through the fan 300 and enters the inside of the housing 200, and finally drops on the bottom of the housing 200. Part of the raindrops will bounce back to the electronic control box 400 after being impacted.

Therefore, by arranging the two water baffles 440 along the first direction F1, on one hand, the two water baffles 440 arranged alternately up and down can define the air inlet 420, so as to ensure that the air flow can smoothly enter the accommodating cavity 410; on the other hand, the orthographic projections of the two water baffles 440 on the plane perpendicular to the first direction F1 at least partially overlap, that is, the wind inlet 420 is formed in a shape of a circle, and the water drops bouncing upwards can be completely blocked by the two water baffles 440 one after the other. The probability of water drops entering the accommodating cavity 410 can be further reduced, and further, the influence of water on the normal operation of the components such as the electronic control module 411, the communication module 412 and the like in the electronic control box 400 can be effectively reduced. The operation efficiency and the use reliability of the electronic control box 400 are improved.

In some embodiments, the electronic control box 400 is provided with a heat sink 450 at the intake vent 420.

By arranging the heat sink 450 at the air inlet 420, on one hand, the heat dissipation effect of the electronic control box 400 can be improved; in another direction, the heat sink 450 is disposed at the air inlet 420 to define a plurality of smaller air inlet channels at the air inlet 420, so as to effectively reduce the probability of water drops and/or microorganisms entering the accommodating cavity 410, and improve the operation efficiency and the use reliability of the electronic control box 400.

Further, in other embodiments, the heat sink 450 may be installed at the air outlet 430, or any other area inside the accommodating chamber 410, etc., without being limited thereto.

Referring to fig. 2, 3-5, in some embodiments, the electronic control box 400 has two air inlets 420, and the two air inlets 420 are respectively used for guiding the air flow to different areas in the accommodating chamber 410.

It is understood that the receiving chamber 410 is installed with the heat sink 450, the electronic control module 411 and the communication module 412, which are disposed at different areas of the receiving chamber 410. The air flow enters the accommodating chamber 410 through the air inlet 420 and then flows out of the air outlet 430, and the path of the air flow is fixed and single, and passes through each component installed in the accommodating chamber 410 in sequence. Correspondingly, the temperature of the airflow rises after the airflow passes through the first component and takes away the heat of the component; thereby reducing the heat absorption capacity of the second component in other areas. By analogy, the heat dissipation effect of the components disposed near the air inlet 420 is the best, and the heat dissipation capability of the components disposed far away from the air inlet 420 and near the air outlet 430 is poorer.

By providing two air intakes 420 and directing the air flow to different areas within the receiving cavity 410, respectively. The air flow with the same temperature can be guided to different components in the electronic control box 400, and the heat dissipation efficiency of the electronic control box 400 is improved.

Preferably, two air intakes 420 may be provided to direct air flow to the area where the electronic control module 411 and the heat sink 450 are located.

The two components have more and concentrated heat accumulation, and the heat dissipation efficiency of the electronic control box 400 can be further improved.

Further, in other embodiments, the electronic control box 400 may further include 3 air inlets 420, 4 air inlets 420, etc., which are not limited herein.

In some embodiments, the electrical control box 400 defines an air outlet channel 470 at the air outlet 430, which is communicated with the accommodating cavity 410, and at least a portion of the air outlet channel 470 extends obliquely in a direction away from the fan 300 in the first direction F1.

It should be noted that the air duct 210 of the top air-out type outdoor unit 100 extends vertically upward, and raindrops may drop into the casing 200; when the fan 300 is started, the fan blades rotating at a high speed can hit a part of raindrops and form small water drops moving in all directions, namely water mist, and the phenomenon is most obvious in an area near the fan 300. The air outlet 430 is disposed close to the blower 300 relative to the air inlet 420, and small water droplets moving in all directions may enter the electronic control box 400 from the air outlet 430, thereby causing a safety hazard to the normal operation of the electronic control box 400.

By extending at least a part of the air outlet channel 470 obliquely in a direction away from the fan 300 in the first direction F1; namely, part of the wind outlet channel 470 is arranged obliquely downward. The water drops can be effectively prevented from entering the accommodating cavity 410, and the use reliability of the electric control box 400 is improved.

Preferably, in the first direction F1, the air outlet channel 470 extends obliquely away from the fan 300. That is, the air outlet channel 470 is disposed obliquely downward. The air outlet channel 470 can be a smooth linear channel, and the air flow passing efficiency is improved. The blockage of the electric control box 400 to the fan 300 can be reduced, and the utilization rate of the space in the shell 200 can be improved.

In some embodiments, an included angle between the extending direction of the air outlet channel 470 and the first direction F1 is B, where B satisfies: b is more than or equal to 30 degrees and less than or equal to 45 degrees.

Through the experimental discovery of researcher, when air-out passageway 470 was in this angular range, not only can effectively block that the water droplet enters into automatically controlled box 400 inside, can also make the air current more smooth and easy through air-out passageway 470, improved the radiating efficiency of automatically controlled box 400.

Further, in other embodiments, B may also satisfy: b is more than or equal to 20 degrees and less than 30 degrees, or B is more than 45 degrees and less than or equal to 60 degrees, and the like, and the limitation is not excessive.

Referring to fig. 2 to 4 and fig. 6, in some embodiments, the air outlet channel 470 is provided with a plurality of baffles 480 at intervals.

By providing a plurality of baffles 480, the air outlet channel 470 can be divided into a plurality of fine flow guide channels. On one hand, the air flow can be smoother through the air outlet channel 470, so that the generation of local turbulence is avoided, and the heat dissipation efficiency of the electric control box 400 is improved; on the other hand, the cross-sectional area of the flow guide channel is much smaller than that of the air outlet channel 470, so that microorganisms and/or impurities can be effectively prevented from entering the accommodating cavity 410, and the use reliability of the electric control box 400 is improved.

Specifically, the accommodating cavity 410 in the electronic control box 400 may be formed by enclosing a plurality of side plates, the electronic control box 400 further includes an air duct cover 460, and the air duct cover 460 is covered on the side plates of the accommodating cavity 410 and forms an air outlet channel 470; the baffle 480 is disposed within the duct cover 460.

Optionally, the baffle 480 is further provided with a plurality of micro holes (not shown).

Set up a plurality of micropores on water conservancy diversion piece 480, can make the air current offset in the different water conservancy diversion passageways, and then noise abatement improves user experience.

Preferably, the shape of the micro-holes is circular.

Further, in other embodiments, the shape of the micro-holes may be rectangular, irregular, etc., and is not limited herein.

In some embodiments, a flared vent (not shown) is also provided on the side wall of the electrical control box 400.

It can be understood that, the air flow enters the accommodating cavity 410 through the air inlet 420 and then flows out of the air outlet 430, and the path of the air flow is relatively fixed; and under the influence of each side wall of the electronic control box 400, part of the air flow is easy to form a vortex in the accommodating cavity 410, and the heat dissipation effect of the electronic control box 400 is influenced.

The side wall of the electric control box 400 is provided with the vent hole, so that air flow in partial vortex can be divided, and the heat dissipation efficiency of the electric control box 400 is improved; in particular, the flared vent holes formed in the side walls can not only block water droplets from entering the electronic control box 400, but also accelerate the flow rate of the air flow, thereby further increasing the air flow passing through the electronic control box 400.

In some embodiments, a condenser (not shown) and a compressor (not shown) are further disposed in the electronic control box 400, and both the condenser and the compressor are disposed in the housing 200, and the condenser and the compressor are connected by a refrigerant pipe (not shown).

Specifically, the compressor and the condenser are electrically connected with the electric control assembly. An evaporator (not shown) in an indoor unit (not shown) transmits the high-temperature gaseous refrigerant to a compressor, and the compressor compresses the high-temperature gaseous refrigerant into a high-pressure high-temperature gaseous refrigerant and transmits the high-pressure high-temperature gaseous refrigerant to a condenser through a refrigerant pipe; the high-pressure high-temperature gaseous refrigerant is released heat in the condenser and changed into liquid refrigerant, and finally enters the evaporator again through an expansion valve (not shown), and low-temperature gaseous refrigerant is formed in the evaporator to absorb heat. Finally, the indoor temperature is reduced, so that comfortable cool wind is brought to a user, and the user experience is improved.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

The air conditioner outdoor unit 100 provided in the embodiment of the present application is described in detail above, and a specific example is applied to illustrate the principle and the implementation manner of the present application, and the description of the embodiment is only used to help understanding the technical solution and the core idea of the present application; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
