[0037] In the description of the present utility model, "a plurality" means two or more, and "several" means one or more.

[0038] The outdoor unit 1 of an air conditioner according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0039] As Figures 1 - 10 shown, the outdoor unit 1 of the air conditioner according to an embodiment of the present utility model includes a housing 100, a compressor 200, an outdoor heat exchanger 210, and a blower 220.

[0040] An air inlet is provided on the outer periphery of the housing 100, and an air outlet 160 is provided at the top. The compressor 200 is disposed inside the housing 100. The outdoor heat exchanger 210 is disposed inside the housing 100 and is used for heat exchange with outdoor air. The blower 220 is disposed inside the housing 100, and the blower 220 drives outdoor air to flow through the air inlet, the outdoor heat exchanger 210, and the air outlet 160 in sequence.

[0041] The housing 100 includes a base 110, a housing 120, and an air outlet grille. The housing 120, the compressor 200, and the outdoor heat exchanger 210 are fixed to the base 110, and the compressor 200 and the outdoor heat exchanger 210 are disposed inside the housing 120. The housing 120 is provided with an air inlet, and the air outlet grille is disposed at the top of the housing 120. The blower 220 is fixed to the air outlet grille, and the air outlet grille is provided with the air outlet 160.

[0042] Among them, there are multiple air inlets. The multiple air inlets include multiple first air inlets 130 and multiple second air inlets 140. The first air inlets 130 are located above the second air inlets 140, and the air inlet area of at least one second air inlet 140 is larger than that of the first air inlet 130.

[0043] Among them, the shape of the air inlet in the embodiment of the present utility model can be a rectangle in the drawings, but not limited thereto. For example, the shape of the air inlet can be a circle, a polygon, an ellipse, etc., as long as the air inlet area of the second air inlet 140 is larger than that of the first air inlet 130. At the same time, the shapes and sizes of the multiple second air inlets 140 can be the same or different, and the shapes and sizes of the multiple first air inlets 130 can also be the same or different.

[0044] For the outdoor unit 1 of the air conditioner according to an embodiment of the present utility model, an air inlet is provided on the outer periphery of the housing 100, and an air outlet 160 is provided at the top. The compressor 200 is disposed inside the housing 100. The outdoor heat exchanger 210 is disposed inside the housing 100 and is used for heat exchange with outdoor air. The blower 220 is disposed inside the housing 100, and the blower 220 drives outdoor air to flow through the air inlet, the outdoor heat exchanger 210, and the air outlet 160 in sequence.

[0045] In this way, when the outdoor unit 1 of the air conditioner operates, the fan 220 rotates. The fan 220 can drive outdoor air to enter the housing 100 from the air inlets around the housing 100, and flow through the outdoor heat exchanger 210. As a result, the refrigerant flowing through the outdoor heat exchanger 210 can exchange heat with the outdoor air entering the housing 100. If the air conditioner is cooling the indoor space at this time, the indoor heat exchanger of the air conditioner acts as an evaporator, and the outdoor heat exchanger 210 can act as a condenser. The refrigerant flowing through the outdoor heat exchanger 210 can release heat to the outdoor air. If the air conditioner is heating the indoor space at this time, the indoor heat exchanger of the air conditioner acts as a condenser, and the outdoor heat exchanger 210 can act as an evaporator. The refrigerant flowing through the outdoor heat exchanger 210 can absorb heat from the outdoor air. Finally, the outdoor air after heat exchange through the outdoor heat exchanger 210 is discharged from the housing 100 of the outdoor unit 1 of the air conditioner through the air outlet 160.

[0046] In addition, the housing 100 includes a base 110, a housing 120 and an air outlet grille. The housing 120, the compressor 200 and the outdoor heat exchanger 210 are fixed to the base 110, and the compressor 200 and the outdoor heat exchanger 210 are arranged inside the housing 120. The housing 120 is provided with air inlets, and the air outlet grille is arranged at the top of the housing 120. The fan 220 is fixed to the air outlet grille, and the air outlet grille is provided with an air outlet 160. Among them, the compressor 200 and the fan 220 can be arranged inside the outdoor heat exchanger 210. In this way, when the fan 220 drives outdoor air to flow into the housing 100 from the air inlets and then be discharged from the housing 100 through the air outlet 160, the outdoor air entering the housing 100 through the air inlets can first flow through the outdoor heat exchanger 210, so that the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0047] In addition, there are multiple air inlets. The multiple air inlets can include multiple first air inlets 130. In this way, outdoor air can enter the housing 100 through the multiple first air inlets 130 to ensure sufficient air volume of the outdoor air entering the housing 100, so that the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0048] The multiple air inlets can also include multiple second air inlets 140. In this way, outdoor air can enter the housing 100 through the multiple second air inlets 140 to ensure sufficient air volume of the outdoor air entering the housing 100, so that the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0049] In some specific embodiments, there are multiple air inlets, and the multiple air inlets may include multiple first air inlets 130 and multiple second air inlets 140. The first air inlets 130 are located above the second air inlets 140, and the air inlet area of at least one second air inlet 140 is larger than that of the first air inlet 130. With such a setting, outdoor air can enter the housing 100 through the multiple first air inlets 130 and the multiple second air inlets 140, and the air intake volume is more sufficient, further improving the sufficiency of the heat exchange between the outdoor heat exchanger 210 and the outdoor air.

[0050] Moreover, the fan 220 is fixed to the air outlet grille, and the air outlet grille is arranged at the top of the housing 120. That is, the fan 220 is relatively close to the first air inlet 130 and relatively far from the second air inlet 140. The air inlet area of at least one of the multiple second air inlets 140 located at the lower side is larger than that of the first air inlet 130. That is, the air inlet area of the air inlet farther from the fan 220 can be larger than that of the air inlet closer to the fan 220.

[0051] It can be understood that the air inlet speed of the first air inlet 130 closer to the fan 220 is relatively large, and the air inlet speed of the second air inlet 140 farther from the fan 220 is relatively small. By setting the air inlet area of the second air inlet 140 to be larger, the air intake volume of the second air inlet 140 can be increased, so that the air intake from the first air inlet 130 and the second air inlet 140 can be more uniform. The outdoor air entering the housing 100 from the multiple air inlets can exchange heat with the outdoor heat exchanger 210 more evenly, and the heat exchange is more uniform and sufficient, and the heat exchange effect is better.

[0052] In this way, the outdoor unit 1 of the air conditioner according to the embodiment of the present invention can increase the air intake volume at the part with a relatively small wind speed, and the air intake uniformity is better.

[0053] In some specific embodiments of the present invention, such as Figure 2 、 Figure 5 and Figure 7 shown, the multiple first air inlets 130 are arranged along the circumferential direction of the housing 120 to form a first air inlet row 131. In this way, the multiple first air inlets 130 can better cover the upper side of the housing 120 in the circumferential direction of the housing 120. That is, the coverage area of the multiple first air inlets 130 on the upper side of the housing 120 can be larger, and outdoor air can enter along the circumferential direction of the housing 120, which is beneficial to increasing the air intake volume from the multiple first air inlets 130, so that the air intake volume on the upper side of the housing 120 is sufficient, and the outdoor heat exchanger 210 can exchange heat with the outdoor air sufficiently.

[0054] In some other specific embodiments of the present invention, such as Figure 4 and Figure 7As shown, a plurality of second air inlets 140 are arranged circumferentially along the housing 120 to form a second air inlet row 141. In this way, the plurality of second air inlets 140 can better cover the lower side of the housing 120 in the circumferential direction of the housing 120, that is, the coverage area of the plurality of second air inlets 140 on the lower side of the housing 120 can be larger, and outdoor air can enter the air along the circumferential direction of the housing 120, which is beneficial to increasing the air intake volume from the plurality of second air inlets 140, so that the air intake volume on the lower side of the housing 120 is sufficient, and the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0055] In some specific embodiments of the present invention, such as Figure 2 , Figure 5 and Figure 7 As shown, there are a plurality of first air inlet rows 131, and the plurality of first air inlet rows 131 are arranged in the up and down direction. In this way, the plurality of first air inlet rows 131 can cover the upper side of the housing 120 in the up and down direction, that is, the coverage area of the plurality of first air inlet rows 131 on the upper side of the housing 120 can be larger, the air intake volume of the plurality of first air inlet rows 131 can be larger, further increasing the air intake volume on the upper side of the housing 120, and the outdoor heat exchanger 210 can fully exchange heat with more outdoor air.

[0056] In some other specific embodiments of the present invention, such as Figure 4 and Figure 7 As shown, there are a plurality of second air inlet rows 141, and the plurality of second air inlet rows 141 are arranged in the up and down direction. In this way, the plurality of second air inlet rows 141 can cover the lower side of the housing 120 in the up and down direction, that is, the coverage area of the plurality of second air inlet rows 141 on the upper side of the housing 120 can be larger, the air intake volume of the plurality of second air inlet rows 141 can be larger, further increasing the air intake volume on the lower side of the housing 120, and the outdoor heat exchanger 210 can fully exchange heat with more outdoor air.

[0057] In some specific embodiments of the present invention, such as Figure 4 and Figure 7 As shown, the number of rows of the second air inlet row 141 is less than the number of rows of the first air inlet row 131.

[0058] It can be understood that during the operation of the fan 220, the air intake speed of most air inlets is relatively large, and only the air inlets near the lower side of the housing 120 are far from the fan 220, and the air intake speed of this part of the air inlets will be relatively small. By setting the air intake area of this part of the air inlets to be larger, the air intake volume of the air inlets on the lower side of the housing 120 can be increased, so as to ensure better air intake uniformity on the upper and lower sides of the housing 120.

[0059] Moreover, by setting the number of rows of the second air inlet rows 141 to be less than the number of rows of the first air inlet rows 131, it is possible to avoid an excessive number of the second air inlet rows 141, that is, to avoid an overly large area occupied by multiple second air inlets 140 in the up and down directions of the housing 120. The second air inlet rows 141 can be relatively far from the fan 220. Furthermore, it is possible to avoid an overly large air inlet area for the air inlets that are relatively close to the fan 220, so that the air intake volumes of the first air inlet 130 and the second air inlet 140 can be relatively close, ensuring the air intake uniformity of multiple air inlets and better air intake uniformity in different parts of the housing 120.

[0060] In addition, it should be noted that the number of the first air inlets 130 in multiple first air inlet rows 131 can be the same, and the number of the second air inlets 140 in multiple second air inlet rows 141 can be the same. This can ensure the uniform distribution of multiple first air inlets 130 and the uniform distribution of multiple second air inlets 140, and the air intake uniformity of multiple air inlets is better.

[0061] In some specific embodiments of the present invention, such as Figure 4 and Figure 7 as shown, along the up and down direction, the height of the second air inlet 140 is equal to the height of the first air inlet 130. With this setting, in the up and down direction, the sizes of a single first air inlet 130 and a single second air inlet 140 can be the same, which is beneficial to simplifying the structure of multiple air inlets and facilitating the arrangement of multiple air inlets in the up and down direction.

[0062] In addition, along the circumferential direction of the housing 120, the size of the second air inlet 140 is larger than the size of the first air inlet 130. Specifically, in the up and down direction, the sizes of the first air inlet 130 and the second air inlet 140 are the same, and in the circumferential direction of the housing 120, the size of the second air inlet 140 is larger than the size of the first air inlet 130. Thus, the air intake area of the second air inlet 140 can be larger than the air intake area of the first air inlet 130. When the air intake speed of the second air inlet 140 is less than the first air intake speed, by increasing the air intake area of the second air inlet 140, the air intake volume of the second air inlet 140 can be increased, so that the air intake volume of the second air inlet 140 and the air intake volume of the first air inlet 130 can be relatively close, ensuring uniform air intake in different parts of the housing 120 and more uniform heat exchange between the outdoor heat exchanger 210 and the outdoor air.

[0063] In some specific embodiments of the present invention, such as Figure 2 、 Figure 5 and Figure 7 as shown, multiple air inlets can include a third air inlet 150.

[0064] The third air inlet 150 is located between two adjacent second air inlets 140 of the second air inlet row 141, and the air inlet area of the third air inlet 150 is not less than the air inlet area of the first air inlet 130.

[0065] That is to say, the third air inlet 150 can correspond to the second air inlet 140 in the up-down direction, that is, the third air inlet 150 is also adjacent to the lower side of the housing 120. Among them, the air inlet area of the third air inlet 150 can be smaller than the air inlet area of the second air inlet 140.

[0066] For example, the air inlet area of the third air inlet 150 can be larger than the air inlet area of the first air inlet 130, so as to ensure that the air inlet volume of the third air inlet 150 can be larger, so as to increase the air inlet volume of the air inlets adjacent to the lower side of the housing 120 and ensure the uniformity of the air inlet on the upper and lower sides of the housing 120.

[0067] In addition, the air inlet area of the third air inlet 150 can also be equal to the air inlet area of the first air inlet 130. For example, the shape of the third air inlet 150 and the shape of the first air inlet 130 can be the same, which is beneficial to simplifying the structure of the third air inlet 150, and then can simplify the structure of the housing 120, facilitate the processing and manufacturing of the housing 120, and reduce the processing cost.

[0068] It can be understood that the second air inlet 140 has a relatively large size in the circumferential direction of the housing 120. By arranging the third air inlet 150 between two adjacent second air inlets 140, a vertical rib will be formed between the third air inlet 150 and the second air inlet 140. In this way, the vertical ribs on both sides of the third air inlet 150 can be used to support the housing 120 to strengthen the structural strength of the housing 120 and prevent the structural strength of the lower side of the housing 120 from being too low.

[0069] Furthermore, as Figure 2 、 Figure 5 and Figure 7 shown, along the length direction of the second air inlet row 141, at least one third air inlet 150 is located in the middle of the second air inlet row 141.

[0070] Specifically, when each second air inlet row 141 is provided with two second air inlets 140, the third air inlet 150 located between the two second air inlets 140 can be located in the middle of the second air inlet row 141; when each second air inlet row 141 is provided with more than two second air inlets 140, one of the multiple third air inlets 150 can be located in the middle of the second air inlet row 141. Such a setting can ensure that the structural strength of the housing 120 at the position adjacent to the middle of the second air inlet row 141 can be relatively high, which is beneficial to improving the structural strength of the housing 120 and preventing the housing 120 from deforming.

[0071] In some other specific embodiments of the present utility model, along the up-and-down direction from top to bottom, the air inlet areas of multiple air inlets gradually increase.

[0072] It can be understood that along the up-and-down direction from top to bottom, the distances between the multiple air inlets and the fan 220 gradually increase, and the air inlet wind speed of the air inlet farther away from the fan 220 is smaller. By making the air inlet areas of the multiple air inlets gradually increase in the direction from top to bottom, the air inlet area of the air inlet farther away from the fan 220 will be larger.

[0073] Thus, along the up-and-down direction from top to bottom, the air inlet wind speed of the air inlet farther away from the fan 220 is smaller and the air inlet area is larger, so that the air inlet volumes of the multiple air inlets can be made close to each other, ensuring that the air inlet volumes of the air inlets at different upper and lower parts of the housing 120 can be close to each other, and the heat exchange amounts at different parts of the heat exchanger can be close to each other, making the heat exchange more uniform.

[0074] In some specific embodiments of the present utility model, as Figure 1 and Figure 3 shown, multiple side walls of the housing 120 are each provided with an air inlet, and the outdoor heat exchanger 210 covers the air inlet. In this way, the outdoor air entering the housing 100 from the air inlet can all flow through the outdoor heat exchanger 210, and the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0075] In addition, along the up-and-down direction, the height of the outdoor heat exchanger 210 is not less than the height of the housing 120. In this way, in the up-and-down direction, the outdoor heat exchanger 210 can cover the housing 120, so that the outdoor heat exchanger 210 can cover multiple air inlets, ensuring that the outdoor air entering the housing 100 from the air inlet can all flow to the outdoor heat exchanger 210, enabling the outdoor heat exchanger 210 to fully exchange heat with the outdoor air. Moreover, the housing 120 and the outdoor heat exchanger 210 can be connected to each other to improve the connection strength of the housing 120, the outdoor heat exchanger 210, and the base 110, and the overall structural strength of the outdoor unit 1 of the air conditioner can be higher.

[0076] As Figures 1 - 10 shown, the outdoor unit 1 of the air conditioner according to an embodiment of the present utility model includes a housing 100, a compressor 200, an outdoor heat exchanger 210, and a fan 220.

[0077] The outer periphery of the housing 100 is provided with an air inlet and the top is provided with an air outlet 160. The compressor 200 is disposed inside the housing 100. The outdoor heat exchanger 210 is disposed inside the housing 100 and is used for heat exchange with outdoor air. The fan 220 is disposed inside the housing 100, and the fan 220 drives the outdoor air to sequentially flow through the air inlet, the outdoor heat exchanger 210, and the air outlet 160.

[0078] The housing 100 includes a base 110, a casing 120, and an air outlet grille. The casing 120, the compressor 200, and the outdoor heat exchanger 210 are fixed to the base 110, and the compressor 200 and the outdoor heat exchanger 210 are disposed inside the casing 120. The casing 120 is provided with an air inlet, and the air outlet grille is disposed at the top of the casing 120. The fan 220 is fixed to the air outlet grille, and the air outlet grille is provided with an air outlet 160.

[0079] Among them, there are multiple air inlets, and the multiple air inlets include multiple first air inlets 130 and multiple second air inlets 140. The first air inlets 130 are located above the second air inlets 140, and the air inlet area of at least one second air inlet 140 is larger than that of the first air inlet 130.

[0080] According to the air conditioner outdoor unit 1 of the embodiment of the present utility model, the outer periphery of the housing 100 is provided with an air inlet and the top is provided with an air outlet 160. The compressor 200 is disposed inside the housing 100, the outdoor heat exchanger 210 is disposed inside the housing 100 and is used for heat exchange with outdoor air, and the fan 220 is disposed inside the housing 100. The fan 220 drives the outdoor air to flow through the air inlet, the outdoor heat exchanger 210, and the air outlet 160 in sequence.

[0081] In this way, when the air conditioner outdoor unit 1 is working, the fan 220 operates. The fan 220 can drive the outdoor air to enter the housing 100 from the air inlets around the housing 100 and flow through the outdoor heat exchanger 210. Furthermore, the refrigerant flowing through the outdoor heat exchanger 210 can exchange heat with the outdoor air entering the housing 100. If the air conditioner is cooling the indoor space at this time, the indoor heat exchanger of the air conditioner acts as an evaporator, and the outdoor heat exchanger 210 can act as a condenser. The refrigerant flowing through the outdoor heat exchanger 210 can release heat to the outdoor air. If the air conditioner is heating the indoor space at this time, the indoor heat exchanger of the air conditioner acts as a condenser, and the outdoor heat exchanger 210 can act as an evaporator. The refrigerant flowing through the outdoor heat exchanger 210 can absorb heat from the outdoor air. Finally, the outdoor air after heat exchange through the outdoor heat exchanger 210 is discharged from the housing 100 of the air conditioner outdoor unit 1 through the air outlet 160.

[0082] In addition, the housing 100 includes a base 110, a casing 120, and an air outlet grille. The casing 120, the compressor 200, and the outdoor heat exchanger 210 are fixed to the base 110, and the compressor 200 and the outdoor heat exchanger 210 are disposed inside the casing 120. The casing 120 is provided with an air inlet, the air outlet grille is disposed at the top of the casing 120, the blower 220 is fixed to the air outlet grille, and the air outlet grille is provided with an air outlet 160. Among them, the compressor 200 and the blower 220 can be disposed inside the outdoor heat exchanger 210. In this way, when the blower 220 drives the outdoor air to flow into the housing 100 from the air inlet and then be discharged from the housing 100 through the air outlet 160, the outdoor air entering the housing 100 through the air inlet can first flow through the outdoor heat exchanger 210, so that the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0083] In addition, there are multiple air inlets arranged in the up-and-down direction. In this way, the outdoor air can enter the housing 100 through the multiple air inlets to ensure sufficient air volume of the outdoor air entering the housing 100, and the outdoor heat exchanger 210 can fully exchange heat with the outdoor air.

[0084] Moreover, the air inlet areas of the multiple air inlets are not equal, that is, the air inlet areas of the air inlets at different positions can be unequal, and the air inlet areas of the air inlets at different distances from the blower 220 can be different. For example, the air inlet area of the air inlet farther from the blower 220 can be larger, so as to increase the air intake of the air inlet farther from the blower 220, that is, to increase the air intake of the air inlet with a smaller air intake speed, so as to ensure that the air intakes of the multiple air inlets can be close to each other, the air intakes of the multiple air inlets are more uniform, and the heat exchange of the heat exchanger is more uniform.

[0085] The outdoor unit 1 of the air conditioner according to the embodiment of the present invention can increase the air intake at the part with a smaller wind speed, and the air intake uniformity is better.

[0086] The other components and operations of the outdoor unit 1 of the air conditioner according to the embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0087] The outdoor unit 1 of the air conditioner in the present invention performs the refrigeration cycle of the air conditioner by using a compressor 200, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0088] The compressor 200 compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0089] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 200. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled by utilizing the latent heat of evaporation of the refrigerant. During the whole cycle, the indoor unit of the air conditioner can adjust the temperature and humidity of the indoor space.
