[0039] Embodiments of the present application are described in detail below with reference to the accompanying drawings. Embodiments of the present application are described in detail below.

[0040] The following description is made with reference to the accompanying drawings, which are included to provide a thorough understanding of the application. Figures 1-12 The outdoor unit 100 according to embodiments of the present application is described below. The outdoor unit 100 can avoid the risk of short circuit of the circuit board 62 caused by rain, thereby ensuring normal operation of the outdoor unit 100 in a rainy and snowy environment.

[0041] The outdoor unit 100 according to the first aspect of the present application includes a housing 1, a partition 2, a compressor 3, a heat exchange assembly 4, an outdoor fan 5, and an electronic control box 6. The housing 1 mainly serves as an external profile structural member of the outdoor unit 100.

[0042] The indoor unit and the outdoor unit 100 are connected by a pipeline to transmit refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit 100 includes a compressor 3, a four-way valve, a heat exchange assembly 4 (an outdoor heat exchanger), an outdoor fan 5, and a throttling device. The compressor 3, the outdoor heat exchanger, the throttling device, and the indoor heat exchanger connected in sequence form a refrigerant circuit, and the refrigerant circulates in the refrigerant circuit, exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger, respectively, to realize a cooling mode or a heating mode of the air conditioner.

[0043] The compressor 3 is configured to compress the refrigerant to form high-pressure refrigerant by compressing low-pressure refrigerant.

[0044] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transmitted in the outdoor heat exchanger. For example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor 3 is condensed by dissipating heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the refrigerant after pressure reduction is evaporated by absorbing heat of the outdoor air through the outdoor heat exchanger.

[0045] The outdoor fan 5 is configured to suck outdoor air into the air conditioner outdoor unit 100 through the air inlet 12 of the air conditioner outdoor unit 100, and send the outdoor air after heat exchange with the outdoor heat exchanger out through the air outlet 13 of the air conditioner outdoor unit 100. The outdoor fan 5 provides power for the flow of outdoor air.

[0046] The throttling device is connected between the outdoor heat exchanger and the indoor heat exchanger, and the opening degree of the throttling device is adjusted to adjust the refrigerant pressure flowing through the outdoor heat exchanger and the indoor heat exchanger, so as to adjust the refrigerant flow between the outdoor heat exchanger and the indoor heat exchanger. The flow and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The throttling device can be an electronic valve. The opening degree of the electronic expansion valve is adjustable to control the flow and pressure of the refrigerant flowing through the electronic expansion valve.

[0047] The four-way valve is connected in the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit to make the air conditioner execute the cooling mode or the heating mode.

[0048] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transmitted in the indoor heat exchanger. For example, the indoor heat exchanger works as an evaporator in the cooling mode of the air conditioner, so that the refrigerant after heat dissipation through the outdoor heat exchanger is evaporated by absorbing heat of the indoor air through the indoor heat exchanger. The indoor heat exchanger works as a condenser in the heating mode of the air conditioner, so that the refrigerant after heat absorption through the outdoor heat exchanger is condensed by emitting heat to the indoor air through the indoor heat exchanger.

[0049] The air conditioner further comprises a control device. The control device is configured to control the working frequency of the compressor 3, the opening degree of the expansion valve, the rotating speed of the outdoor fan 5 and the rotating speed of the indoor fan. The control device is connected with the compressor 3, the throttling device, the outdoor fan 5 and the indoor fan through data lines to transmit communication information.

[0050] The casing 1 defines an installation cavity 11 inside, and the air inlet 12 and the air outlet 13 are formed on the casing 1.

[0051] Specifically, the air flow flows through the air inlet 12 and the air outlet 13 on the casing 1, realizing the air circulation between the outdoor air flow and the air conditioner outdoor unit 100. The outdoor fan 5 can drive the external air flow to enter the air conditioner outdoor unit 100 from the air inlet 12, and the heat exchange assembly 4 exchanges heat with the external air flow entering from the air inlet 12. The heat exchange air flow formed is blown to the outside from the air outlet 13 under the driving of the outdoor fan 5, so as to exchange the heat between the inside of the air conditioner outdoor unit 100 and the outside, and meet the user's demand for the environmental temperature.

[0052] The partition plate 2 is arranged in the casing 1, and the partition plate 2 divides the mounting cavity 11 into a compressor cavity 111 and a fan cavity 112. The compressor 3 is arranged in the compressor cavity 111, and the outdoor fan 5 is arranged in the fan cavity 112.

[0053] Specifically, the partition plate 2 can divide the mounting cavity 11 inside the casing 1, which can facilitate the effective distinction between the installation arrangement positions of the compressor 3 and the outdoor fan 5 in the casing 1, improve the arrangement regularity, and also block the water droplets on the outdoor fan 5 from splashing onto the compressor 3 and the circuit elements in the compressor cavity 111, thereby reducing the safety risk of the electrical appliance.

[0054] Further, the heat exchange assembly 4 is arranged in the fan cavity 112, so that after the airflow outside the casing 1 enters the fan cavity 112 under the negative pressure action of the outdoor fan 5, the airflow is directly blown out to the outside of the casing 1 after heat exchange through the heat exchange assembly 4, thereby facilitating the smooth realization of the heat exchange effect of the airflow by the air conditioner outdoor unit 100.

[0055] The outdoor fan 5 is used to introduce the airflow outside the casing 1 into the fan cavity 112 through the air inlet 12, and output the airflow outside through the air outlet 13 after heat exchange through the heat exchange assembly 4. The electric control box 6 is arranged in the mounting cavity 11.

[0056] Specifically, the rotation of the outdoor fan 5 can generate negative pressure on the outside of the casing 1 through the air inlet 12, so that the air outside the casing 1 is driven into the fan cavity 112 under the action of air pressure. The airflow entering the fan cavity 112 exchanges heat with the heat exchange assembly 4 in the fan cavity 112. The airflow after heat exchange is output to the outside of the casing 1 through the air outlet 13, so that the heat exchange effect of the refrigerant in the heat exchange assembly 4 and the outdoor air can be realized.

[0057] The electric control box 6 includes an electric control box body 61, a circuit board 62, a power module 65, a refrigerant bracket 63, and a refrigerant radiator 64. The electric control box body 61 spans above the partition plate 2, and the circuit board 62 is arranged in the electric control box body 61.

[0058] Specifically, the circuit board 62 is electrically connected together by electronic components (such as resistors, capacitors, transistors, integrated circuits, etc.) according to a pre-designed circuit diagram, forming a complete circuit system. For example, the circuit board 62 can be electrically connected with the outdoor fan 5 and the compressor 3, respectively.

[0059] Further, the electric control box body 61 can protect the internal structure, and the circuit board 62 can send different control instructions to the outdoor fan 5 and the compressor 3 in the form of electrical signals, thereby improving the sensitivity and accuracy of the outdoor fan 5 and the compressor 3 in the execution of the work instructions.

[0060] The power module 65 is arranged on the circuit board 62, the refrigerant support 63 is arranged in the electric control box 61, the refrigerant support 63 is located on one side of the circuit board 62, and the refrigerant support 63 is arranged adjacent to the power module 65. The refrigerant radiator 64 is in communication with the heat exchange assembly 4, and the refrigerant radiator 64 is arranged on the refrigerant support 63 and used for dissipating heat for the power module 65.

[0061] The power module 65 is mainly used for managing and optimizing the conversion and control of electric energy to support the efficient operation of the air conditioner. For example, the power module 65 can adjust the voltage and frequency of the motor of the compressor 3 to enable the compressor 3 to flexibly adjust the rotating speed according to the actual demand. The power module 65 can also realize the effect of electric energy conversion, that is, the power module 65 first converts the alternating current provided by the power grid into direct current for subsequent fine control, and then inversely converts the direct current into alternating current with adjustable frequency and amplitude for use by the motors of the air conditioning system, such as the motor of the outdoor fan 5 and the motor of the compressor 3.

[0062] The power module 65 is arranged on the circuit board 62. Such an arrangement can ensure more reliable signal transmission between the power module 65 and the control circuit on the circuit board 62, reduce electromagnetic interference (EMI) problems caused by external wiring, and facilitate the integration of a heat dissipation structure for the power module 65, which generates a large amount of heat during operation. In this way, the limited space can be maximally utilized for effective heat management.

[0063] The electric control box 61 can serve as a mounting carrier for the refrigerant support 63, and the refrigerant support 63 can support the refrigerant radiator 64. The refrigerant can flow between the refrigerant radiator 64 and the heat exchange assembly 4, which facilitates the continuous exchange of heat between the refrigerant and the circuit board 62 in the electric control box 61, thereby effectively improving the heat dissipation efficiency of the circuit board 62 and ensuring the normal operation of the outdoor unit 100 of the air conditioner.

[0064] The refrigerant support 63 is located on one side of the circuit board 62 and arranged adjacent to the power module 65, which facilitates the provision of a spatial position of the refrigerant radiator 64 closer to the power module 65, thereby providing spatial arrangement rationality and heat dissipation effect of the power module 65.

[0065] Further, the refrigerant support 63 includes a support body 631 and a plurality of support legs 632. The refrigerant radiator 64 is arranged on the support body 631, and the plurality of support legs 632 are arranged at intervals on the support body 631 and supported on the bottom wall of the electric control box 61.

[0066] It can be understood that the bracket body 631 is mainly used for mounting the refrigerant radiator 64, and the plurality of feet 632 are arranged on the bracket body 631 in a spaced manner, so that a plurality of stress transmission channels are formed between the bracket body 631 and the bottom wall of the electric control box 61, which is beneficial to improve the stress uniformity of the bracket body 631, reduce the risk of stress concentration, and thus ensure the structural stability of the refrigerant bracket 63.

[0067] In particular, since the feet 632 and the bottom wall of the electric control box 61 are usually provided with holes for connecting the feet 632, along the space range of the press cavity 111 in the vertical direction, the plurality of feet 632 are located in the press cavity 111, so that the holes of the feet 632 can be away from the action range of the outdoor fan 5 (in the embodiment of the case, the risk of rain can be avoided in the rain test, wherein the rain test is to spray water outside the grille of the air conditioner outdoor unit, and the outdoor fan is rotated forward and reversely, and the water will be stirred in the casing by the fan, and it is checked whether the water can be splashed to the circuit board), thereby avoiding that the outdoor fan 5 accidentally splashes water drops to the circuit board 62 through the holes of the feet 632 during rotation, and improving the rainproof effect of the circuit board 62.

[0068] Compared with the conventional arrangement of at least one foot of the refrigerant bracket on the side of the partition plate close to the fan cavity, the outdoor fan is easy to splash water droplets on the control board through the hole of the above-mentioned foot, and the embodiment of the case can avoid the risk of rain on the circuit board 62, thereby improving the safety of the circuit board 62 and ensuring that the circuit board 62 can work normally in rainy and snowy days.

[0069] Therefore, by arranging the air conditioner outdoor unit 100, the risk of short circuit of the circuit board 62 caused by rain can be avoided, thereby ensuring the normal operation of the air conditioner outdoor unit 100 in the rainy and snowy environment.

[0070] According to some optional embodiments of the present application, as shown in Figure 5 and Figure 8 It is shown that the bracket body 631 has a first end 6311 close to the partition plate 2 and a second end 6312 away from the partition plate 2 in the length direction thereof, and the plurality of feet 632 are arranged in a spaced manner with the first end 6311 of the bracket body 631.

[0071] The first end 6311 of the support body 631 is close to the partition plate 2 along the length direction of the support body 631, the second end 6312 of the support body 631 is away from the partition plate 2 in a direction away from the fan cavity 112, and the plurality of legs 632 are away from the first end 6311 of the support body 631 by a certain distance. In this way, the legs 632 are farther away from the side of the electric control box body 61 close to the outdoor fan 5, thereby reducing the probability that the water droplets in the fan cavity 112 are splashed to the circuit board 62 through the hole on the electric control box body 61 communicated with the legs 632 by the outdoor fan 5, and thereby avoiding the risk that the electronic components in the electric control box 6 are rained on.

[0072] Specifically, as shown in Figure 4 、 Figure 5 、 Figures 7-9 , the distance from the closest leg 632 of the plurality of legs 632 to the first end 6311 is greater than the distance from the leg 632 to the midpoint of the length direction of the support body 631.

[0073] That is, along the length direction of the support body 631, the closest leg 632 to the first end 6311 deviates as far as possible to the side away from the outdoor fan 5. In this way, the rain risk of the circuit board 62 due to the hole on the electric control box body 61 for connecting the legs 632 can be avoided to the greatest extent while meeting the support demand of the legs 632 to the refrigerant support 63.

[0074] Further, as shown in Figure 4 、 Figure 5 、 Figure 8 and Figure 9 , the plurality of legs 632 are three, and the plurality of legs 632 include a first leg 6321, a second leg 6322 and a third leg 6323. The distance from the first leg 6321 to the first end 6311 is greater than the distance from the first leg 6321 to the midpoint of the length direction of the support body 631. The second leg 6322 and the third leg 6323 are both located between the first leg 6321 and the second end 6312, and the second leg 6322 and the third leg 6323 are spaced apart in the width direction of the support body 631.

[0075] It can be understood that the first leg 6321 and the second leg 6322 are spaced apart from the third leg 6323 in the length direction of the bracket body 631, and the second leg 6322 is further spaced apart from the third leg 6323 in the width direction of the bracket body 631, so that the three legs 632 can jointly form a support effect in different directions of the refrigerant bracket 63, thereby improving the stress stability of the refrigerant bracket 63. Moreover, the three legs 632 can effectively reduce the number of legs 632 and reduce material consumption under the premise of supporting the refrigerant bracket 63 stably, thereby reducing the manufacturing cost.

[0076] Specifically, the first leg 6321 is located at the middle of the width direction of the bracket body 631, so that the arrangement can be beneficial to realize uniform distribution of stress and reduce distortion or deformation caused by eccentric load; and the second leg 6322 and the third leg 6323 are further located at both sides of the width direction of the bracket body 631, respectively, so that the first leg 6321 can jointly form a stable triangular support structure, which can effectively resist lateral force and prevent the refrigerant bracket 63 from tilting or overturning, and can make the weight of the refrigerant bracket 63 more evenly distributed on three points, thereby reducing the pressure borne by a single leg 632 and improving the stability and carrying capacity of the overall structure.

[0077] Further, the second leg 6322 and the third leg 6323 are the same distance from the first leg 6321, so that the arrangement of the three legs 632 can be more regular and standardized, which is beneficial to simplify the production process and improve the manufacturing efficiency.

[0078] According to some optional embodiments of the present application, as shown in Figure 11 and Figure 12 The electric control box 61 is provided with a clamping hole 614, and the leg 632 is provided with a clamping hook 6324, the leg 632 is inserted into the clamping hole 614, and the clamping hook 6324 is clamped on one side of the clamping hole 614.

[0079] The clamping hook 6324 of the leg 632 is inserted into the clamping hole 614 on the electric control box 61, and as the refrigerant bracket 63 and the electric control box 61 are installed and fastened (for example, as the fastener is tightened to fasten the refrigerant bracket 63 and the electric control box 61, the clamping hook 6324 rises with the refrigerant bracket 63), when the refrigerant bracket 63 and the electric control box 61 are fastened in place, the refrigerant bracket 63 and the electric control box 61 are pressed in the vertical direction. The refrigerant radiator 64. Moreover, the clamping hook 6324 and the clamping hole 614 are clamped and matched, so that the movement of the refrigerant bracket 63 can be limited, and the risk of accidental falling of the refrigerant bracket 63 from the electric control box 61 can be prevented.

[0080] According to some optional embodiments of the present application, as shown in Figure 8And Figure 9 As shown in the figure, the first leg 6321 is located on the center line of the width direction of the bracket body 631, and the centers of the first leg 6321, the second leg 6322 and the third leg 6323 are sequentially connected to form an isosceles triangle.

[0081] Among them, since the first leg 6321 is located on the center line of the width direction of the bracket body 631, such arrangement is conducive to achieving uniform distribution of stress, reducing distortion or deformation caused by eccentric load; it can also more effectively absorb and disperse mechanical vibration, reduce vibration transmission and noise level generated during equipment operation; it can also simplify the installation alignment process and improve processing efficiency and assembly efficiency.

[0082] In addition, the centers of the first leg 6321, the second leg 6322 and the third leg 6323 are sequentially connected to form a closed isosceles triangle, which can maximize the simplification of the support structure while ensuring the structural stability of the refrigerant bracket 63. Moreover, the above arrangement can make the arrangement of the three legs 632 more regular and standardized, which is conducive to simplifying the production process and improving manufacturing efficiency.

[0083] Specifically, in combination with Figure 8 And Figure 9 As shown in the figure, the bracket body 631 includes a bottom plate 6313 and a top plate 6314, the refrigerant radiator 64 is arranged on the bottom plate 6313, the plurality of legs 632 are arranged on the bottom plate 6313, and the top plate 6314 is arranged above the bottom plate 6313 and the refrigerant radiator 64. The top plate 6314 is arranged below the circuit board 62 and the power module 65 to conduct heat between the circuit board 62 and the refrigerant radiator 64.

[0084] It can be understood that in the up-down direction, the circuit board 62 is located above the top plate 6314, and the refrigerant radiator 64 and the bottom plate 6313 are arranged below the top plate 6314. The refrigerant radiator 64 is installed and placed on the bottom plate 6313, the legs 632 are supported below the bottom plate 6313, and the top plate 6314 can conduct heat between the power module 65 and the refrigerant radiator 64, thereby achieving the effect of heat exchange of the circuit board 62, and further ensuring the normal operation of the circuit board 62.

[0085] Further, in combination with Figure 8 And Figure 10 As shown in the figure, the top plate 6314 is provided with a first mounting hole 6315, and the top wall of the electric control box body 61 is provided with a second mounting hole 611.
