[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] As an important part of the air conditioner outdoor unit, the electric control box contains many electronic components and circuits, which will generate a lot of heat during long-term operation. In order to maintain the normal operation of these electronic components and prevent damage caused by overheating, the traditional practice is to open heat dissipation holes on the shell of the air conditioner outdoor unit, especially on the side panels or handles. These heat dissipation holes can allow external cold air to enter and take away the heat generated inside the electric control box through natural convection or forced convection, thereby achieving a heat dissipation effect.

[0044] However, the exposed design of the heat dissipation holes will directly affect the appearance of the air conditioner outdoor unit, making the overall appearance less neat and beautiful. In addition, the exposed heat dissipation holes make it easy for external substances such as dust, moisture and insects to enter the interior of the air conditioner outdoor unit through the heat dissipation holes, thereby causing potential damage to the internal electronic components and circuits, and even causing the air conditioner outdoor unit to malfunction.

[0045] To this end, some embodiments of the present invention provide a chassis 140, which is suitable for an air conditioner outdoor unit 10 having a fan 400, a compressor 500 and a middle partition 200. For the convenience of description, the air conditioner outdoor unit 10 is used as an example in the following description. Figures 1 to 9 The following is an explanation.

[0046] Reference Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the air-conditioning outdoor unit 10 includes a housing 130 and a chassis 140, wherein the housing 130 covers the chassis 140 and is detachably connected to the chassis 140. The embodiment does not limit the connection method of the housing 130 and the chassis 140. The housing 130 and the chassis 140 are connected to form the outer shell of the air-conditioning outdoor unit 10, and the interior thereof is a hollow structure, that is, a cavity 100 is provided inside the outer shell.

[0047] Reference Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the air-conditioning outdoor unit 10 further includes a middle partition 200, a fan 400, a compressor 500 and an electric control box 300. Among them, the middle partition 200 is arranged in the cavity 100 and connected to the chassis 140, and the middle partition 200 extends in the up and down direction of the air-conditioning outdoor unit 10, thereby dividing the cavity 100 into a fan cavity 101 and a compression cavity 102. The fan 400 is installed in the fan cavity 101, and the compressor 500 is installed in the compression cavity 102. It can be understood that the fan 400 and the compressor 500 are respectively connected to the chassis 140, and this embodiment does not limit the connection method between the fan 400 and the chassis 140 and the compressor 500 and the chassis 140.

[0048] It is understandable that, referring to Figure 1 and Figure 3 As shown, in the embodiment of the present invention, there is a certain gap between the upper end of the middle partition 200 and the inner wall of the shell 130, and the electric control box 300 is placed horizontally in the gap and connected to the middle partition 200. Part of the electric control box 300 is located in the fan chamber 101, and the other part of the electric control box 300 is located in the compression chamber 102. Figure 4 As shown, the electric control box 300 is provided with a heat dissipation channel 310 connecting the fan chamber 101 and the compression chamber 102. In this embodiment, the heat dissipation channel 310 can be formed by surrounding the original structure of the electric control box 300, or it can be an additional channel for airflow to pass through the electric control box 300, and this embodiment is not limited to this. The heat dissipation channel 310 is adjacent to the heat generating part of the electric control box 300, based on which, when the airflow flows through the heat dissipation channel 310, it can take away the heat generated by the electric control box 300, thereby achieving heat dissipation of the electric control box 300.

[0049] Reference Figure 5As shown, in the embodiment of the utility model, the chassis 140 includes a plate-shaped disc body 144, and the disc body 144 is provided with an air inlet 141 that penetrates the disc body 144 along the up and down direction thereof. It can be understood that when the chassis 140 is connected to the middle partition 200, a part of the disc body 144 is located in the fan chamber 101, and the other part is located in the compression chamber 102. Specifically, the part of the disc body 144 located in the fan chamber 101 is the first installation area 110, and the part of the disc body 144 located in the compression chamber 102 is the second installation area 120. Among them, the air inlet 141 is provided at the part of the disc body 144 located in the compression chamber 102. In this embodiment, since the air inlet 141 penetrates the disc body 144, the air inlet 141 communicates the external environment and the compression chamber 102, and therefore, the air inlet 141 can provide airflow from the external environment to enter the compression chamber 102 and flow to the electric control box 300, thereby dissipating heat for the electric control box 300.

[0050] Specifically, it is understood that referring to Figure 3 As shown, in the embodiment of the utility model, when the fan 400 is in operation, a negative pressure area can be formed in the fan cavity 101. Based on this, since the fan cavity 101 is connected to the compression cavity 102 through the heat dissipation channel 310, the air from the external environment will be sucked into the cavity 100. Specifically, the air from the external environment flows into the compression cavity 102 through the air inlet, and then flows into the fan cavity 101 through the heat dissipation channel 310. When the airflow flows through the heat dissipation channel 310, it takes away the heat generated by the electric control box 300, thereby dissipating the heat from the electric control box 300. It should be noted that Figure 3 The dashed arrows in the figure indicate the direction of air flow.

[0051] It is understandable that, referring to Figure 2 As shown, in the embodiment of the utility model, the housing 130 is provided with an air outlet 160 connected to the fan cavity 101, and the air outlet 160 is provided on the side wall of the housing 130 located at the fan cavity 101. Therefore, the air flowing into the fan cavity 101 can flow out of the air conditioner outdoor unit 10 through the air outlet 160, avoiding the hot air that absorbs the heat generated by the electric control box 300 from accumulating in the cavity 100.

[0052] Reference Figure 1 and Figure 5As shown, in the embodiment of the utility model, the part of the chassis 140 located in the compression chamber 102 is provided with a mounting position for mounting the compressor 500. It can be understood that in order to prevent the compressor 500 from blocking the air intake of the air inlet 141, in the present embodiment, the air inlet 141 and the mounting position of the compressor 500 are arranged at intervals, thereby ensuring the air intake smoothness of the air inlet 141. In addition, the overall profile of the compressor 500 extends upward along the up-and-down direction of the air conditioner outdoor unit 10, and the airflow flowing from the air inlet 141 into the compression chamber 102 also flows upward, so that the airflow can also play a certain heat dissipation role for the compressor 500 when it flows to the heat dissipation channel 310.

[0053] It is understandable that the air inlet 141 of the embodiment of the utility model can not only meet the heat dissipation requirements of the electric control box 300, but also be hidden in the chassis 140 without being exposed, which greatly improves the concealment of the air inlet 141 and reduces the impact of the air inlet 141 on the appearance of the air-conditioning outdoor unit 10. In addition, compared with the existing air-conditioning outdoor unit 10 in which the heat dissipation holes are set on the side wall of the housing 130, the air inlet 141 is set on the disk 144, which can also effectively reduce the entry of external substances such as dust, rainwater and insects into the air-conditioning outdoor unit 10 through the air inlet 141, thereby reducing the risk of damage to the electronic components and circuits in the air-conditioning outdoor unit 10, thereby improving the reliability and stability of the air-conditioning outdoor unit 10.

[0054] In order to further improve the protection of the device in the cavity 100, refer to Figure 6 and Figure 7 As shown, in the embodiment of the utility model, a plurality of baffles 142 are provided at the air inlet 141 to prevent external substances from invading the inner cavity. Specifically, the plurality of baffles 142 are respectively connected to the disk body 144. In one example, the plurality of baffles 142 are integrally formed with the disk body 144. The plurality of baffles 142 are arranged at intervals, and separate the air inlet 141 to form a plurality of air inlet holes 143. It can be understood that the air from the external environment can enter the cavity 100 through each air inlet hole 143. In the present embodiment, each baffle 142 is arranged to tilt downward, which can prevent dust, rain and insects from entering the cavity 100 while not blocking the smooth inflow of airflow.

[0055] In the embodiment of the utility model, along the front-to-back direction of the air-conditioning outdoor unit 10, the inclination angle of the baffle 142 can be gradually softened, so that the air inlet is more inclined toward the front side or the rear side of the air-conditioning outdoor unit 10, thereby further reducing the risk of dust, rainwater and insects entering the cavity 100, especially rainwater that drops on the ground and bounces upward. In one example, along the front-to-back direction of the air-conditioning outdoor unit 10, a plurality of baffles 142 are arranged toward the rear side of the air-conditioning outdoor unit 10 and tilted downward.

[0056] In order to ensure the smoothness of air intake of the air inlet 141 and to achieve sufficient shielding of the air inlet 141 by multiple baffles 142, refer to Figure 7 As shown, in the embodiment of the present invention, along the up-down direction of the disk body 144, the projections of two adjacent baffles 142 on the upper end surface of the disk body 144 are overlapped or staggered. It can be understood that this can ensure that the effective shielding area formed by the multiple baffles 142 can cover the entire air inlet, and the external foreign matter below the air inlet will be blocked by the effective shielding area formed by the multiple baffles 142 if it moves directly upward, thereby further reducing the possibility of external foreign matter entering the cavity 100.

[0057] For the convenience of description, any two adjacent baffles 142 among the multiple baffles 142 are taken as an example in the following description.

[0058] Reference Figure 8 As shown, in the embodiment of the utility model, along the front-to-back direction of the air conditioner outdoor unit 10, one of the two adjacent baffles 142 located at the relatively front side is a first baffle 1421, and the other located at the relatively rear side is a second baffle 1422. Among them, an air inlet hole 143 connecting the external environment and the cavity 100 is formed between the first baffle 1421 and the second baffle 1422, and the air inlet hole 143 faces the rear side. The inlet of the air inlet hole 143 is located between the upper end of the first baffle 1421 and the upper end of the second baffle 1422, and the outlet is between the upper end of the first baffle 1421 and the upper end of the second baffle 1422.

[0059] In one example, a plurality of baffles 142 are arranged seamlessly along the front-to-back direction of the air conditioner outdoor unit 10, so that the rear end of the first baffle 1421 and the front end of the second baffle 1422 are located on the same vertical plane, and the rear end of the first baffle 1421 is located below the front end of the second baffle 1422. The entrance of the air inlet 143 is formed by the upper end surface of the rear end of the first baffle 1421 and the lower end surface of the front end of the second baffle 1422.

[0060] It is understandable that the inventors learned during the experiment that if the minimum width of the air inlet hole 143 is too small, the flow rate and flow rate of the air from the external environment into the cavity 100 will be difficult to meet the heat dissipation requirements of the electric control box 300, and if the minimum width of the air inlet hole 143 is too large, foreign matter from the outside will easily enter the cavity 100 through the air inlet hole 143. Figure 8 As shown, in the embodiment of the utility model, the minimum width of the air inlet hole 143 is L, which satisfies: 1mm (millimeter) ≤ L ≤ 2mm (millimeter), thereby ensuring that the air volume and wind speed flowing into the air inlet hole 143 meet the requirements while reducing the risk of external foreign matter intrusion.

[0061] It is understandable that, according to the actual installation requirements of the air conditioner outdoor unit 10, the air conditioner outdoor unit 10 can be installed on the ground or suspended. When the air conditioner outdoor unit 10 is installed on the ground, in order to prevent the ground from covering the air inlet and making it difficult for the air from the external environment to enter the cavity 100 to dissipate heat for the electric control box 300, refer to Figure 5 and Figure 6 As shown, in the embodiment of the utility model, the bottom surface of the disk body 144 is provided with a base 150. It should be noted that the base 150 can be integrally formed with the disk body 144 and protrude from the bottom surface of the disk body 144, or can be detachably connected to the disk body 144, which is not limited in this embodiment.

[0062] Specifically, in the embodiment of the utility model, along the up-down direction of the plate body 144, the air inlet 141 is higher than the bottom end of the foot 150. It can be understood that the air inlet 141 is higher than the bottom end of the foot 150, which means that the foot 150 can effectively raise the chassis 140, ensuring that the air inlet is kept at a sufficient distance from the ground, thereby ensuring that the air in the external environment can smoothly flow into the cavity 100, providing sufficient heat dissipation air for the electric control box 300.

[0063] Reference Figure 1 and Figure 2 As shown, some embodiments of the utility model provide an air-conditioning outdoor unit 10, comprising a chassis 140, a shell 130, a middle partition 200, a fan 400, a compressor 500 and an electric control box 300 of the above-mentioned embodiments, wherein the shell 130 is covered on the chassis 140 and is surrounded by the chassis 140 to form a cavity 100; the middle partition 200 is arranged in the cavity 100 and connected to the upper end surface of the disk body 144, and the middle partition 200 is used to divide the cavity 100 into a fan cavity 101 and a compression cavity 102; the fan 400 is installed in the fan cavity 101; the compressor 500 is installed in the compression cavity 102; the electric control box 300 is arranged in the cavity 100 and is located at the upper end of the middle partition 200, and the electric control box 300 is provided with a heat dissipation channel 310 connecting the fan cavity 101 and the compression cavity 102.

[0064] The air conditioner outdoor unit 10 of this embodiment adopts the chassis 140 of the above embodiment, and the air inlet 141 is set in the compression chamber 102 of the chassis 144. The fan 400 is installed in the fan chamber 101, and the electric control box 300 is set on the upper side of the middle partition 200. The electric control box 300 is provided with a heat dissipation channel 310 connecting the fan chamber 101 and the compression chamber 102. When the fan 400 is running, a negative pressure area can be formed in the fan chamber 101, and cold air from the external environment can enter through the air inlet 141 of the chassis 140. The air flows through the compression chamber 102 and passes through the heat dissipation channel 310, thereby realizing the heat dissipation of the electronic control box 300. Not only does the air inlet 141 meet the heat dissipation demand, but the air inlet 141 can also be hidden in the chassis 140 without being exposed, which greatly improves the concealment of the air inlet 141 and reduces the impact of the air inlet 141 on the appearance of the air-conditioning outdoor unit 10; the air inlet 141 is arranged on the disk 144, which can also effectively reduce external foreign objects such as dust, rainwater and insects from entering the air-conditioning outdoor unit 10 through the air inlet 141.

[0065] Since the air-conditioning outdoor unit 10 adopts all the technical solutions of the chassis 140 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0066] Reference Figure 4 and Fig. 9 As shown, in an embodiment of the utility model, the electric control box 300 is provided with an air inlet 320 and an air outlet 330, wherein the air inlet 320 can be used as the entrance of the heat dissipation channel 310 and is arranged in the part of the electric control box 300 located in the compression chamber 102, and the air outlet 330 can be used as the exit of the heat dissipation channel 310 and is arranged in the part of the electric control box 300 located in the fan chamber 101.

[0067] Reference Figure 4 and Fig. 9 As shown, in the embodiment of the utility model, the portion of the electric control box 300 located in the fan cavity 101 is provided with an air guide plate 340, which is arranged on one side of the air outlet 330 and extends downward. Based on this, the hot air flowing out of the air outlet 330 can flow downward under the guiding effect of the air guide plate 340, thereby reducing the possibility of hot air accumulating in the upper part of the fan cavity 101.

[0068] Some embodiments of the present invention provide an air conditioner (not shown in the figures), comprising the air conditioner outdoor unit 10 of the above embodiment.

[0069] The air conditioner of the present embodiment adopts the air conditioning outdoor unit 10 of the above-mentioned embodiment, and by arranging an air inlet 141 on the chassis 140 of the air conditioning outdoor unit 10, the concealment of the air inlet 141 is greatly improved, and the influence of the air inlet 141 on the appearance of the air conditioning outdoor unit 10 is greatly reduced, so that the appearance of the air conditioner is neat and beautiful; in addition, the air inlet 141 is arranged on the chassis 140, which can effectively reduce the external foreign matter such as dust, rainwater and insects from entering the air conditioning outdoor unit 10 through the air inlet 141, thereby reducing the risk of damage to the electronic components and circuits in the air conditioning outdoor unit 10, thereby improving the reliability and stability of the air conditioner.
