[0034] 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.

[0035] In the description of the utility model, if there is a description of first and 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.

[0036] 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.

[0037] Reference Figures 1 to 10 The utility model discloses a heat dissipation structure of an air conditioner outdoor unit, including a shell 100, a partition assembly 200 and a valve blade 300.

[0038] The partition assembly 200 is arranged in the housing 100, and the partition assembly 200 divides the housing 100 into a fan chamber 110 and an electrical chamber 120. The fan chamber 110 is used to accommodate the fan blade 130. When the fan blade 130 rotates, a negative pressure is formed in the fan chamber 110. The electrical chamber 120 is used to accommodate the electrical component 140. The partition assembly 200 has a first heat dissipation hole 211. One end of the first heat dissipation hole 211 is connected to the electrical chamber 120, and the other end can be connected to the fan chamber 110. The valve blade 300 is arranged on the partition assembly 200, and the valve blade 300 has an open state and a closed state. When the valve blade 300 is in the open state, the electrical chamber 120 is connected with the fan chamber 110 through the first heat dissipation hole 211. When the valve blade 300 is in the closed state, the first heat dissipation hole 211 and the fan chamber 110 are isolated from each other. The valve blade 300 is configured to be switched to the open state when negative pressure is formed in the fan chamber 110 and to be switched to the closed state after the fan blade 130 stops rotating.

[0039] It is understandable that when the fan blade 130 rotates, negative pressure will be formed in the fan chamber 110. At this time, the valve blade 300 will switch to an open state, so that the electrical chamber 120 is connected to the fan chamber 110 through the first heat dissipation hole 211. The heat in the electrical chamber 120 will be drawn out of the electrical chamber 120 under the action of negative pressure. The fan blade 130 can discharge the heat to the outside of the housing 100, which plays a role in heat dissipation for the electrical components 140 in the electrical chamber 120; when the fan blade 130 stops rotating, the negative pressure in the fan chamber 110 disappears and becomes normal pressure. At this time, the valve blade 300 will switch to a closed state, so that the electrical chamber 120 is isolated from the first heat dissipation hole 211, that is, the electrical chamber 120 is isolated from the fan chamber 110, to ensure that dust and insects will not enter the electrical chamber 120. In summary, the utility model can dissipate heat for the electrical components 140 when the air conditioner is running, and block the heat dissipation holes when heat dissipation is not required to eliminate safety hazards.

[0040] like Figure 7 As described above, the upper end of the valve blade 300 is hinged to the partition assembly 200. When the fan blade 130 rotates and forms a negative pressure in the fan chamber 110, the valve blade 300 is flipped over by the negative pressure and switched to an open state. When the fan blade 130 stops rotating, the valve blade 300 falls back under its own gravity and switches to a closed state. It can be understood that the weight of the valve blade 300 in this embodiment needs to be set so that it can be sucked up and switched to an open state when a negative pressure is generated in the fan chamber 110, and can be changed back to a closed state under the action of gravity when the fan chamber 110 becomes a normal pressure. It should be noted that the upper end of the valve blade 300 can be provided with a hinge shaft 320, and the hinge shaft 320 can be inserted into the valve base 500.

[0041] It should be noted that if Fig. 9 and Fig.10 As shown, in another embodiment of the valve blade 300 of the present invention, the valve blade 300 and the valve base 500 may also be connected via a hinge 330 , and the hinge 330 is disposed at the top of the valve blade 300 .

[0042] It can be understood that in an embodiment where the valve blade 300 is not flipped under the action of negative pressure and deadweight, the valve blade 300 can also be flipped by motor control. Specifically, when the motor receives a signal that the fan blade 130 is rotating, the motor controls the valve blade 300 to rotate a certain angle so that the valve blade 300 becomes an open state, and when the motor receives a signal that the fan blade 130 stops rotating, the motor controls the valve blade 300 to rotate in the opposite direction by a certain angle so that the valve blade 300 becomes a closed state.

[0043] like Figures 1 to 3 as well as Figure 8 As shown, in one embodiment of the present utility model, it also includes a valve base 500, the partition assembly 200 includes a partition body 210, a first heat dissipation hole 211 is opened on the partition body 210, the valve base 500 is directly arranged on the partition body 210, the valve leaf 300 is located on the side of the valve base 500 away from the first heat dissipation hole 211, the upper end of the valve leaf 300 is hinged to the valve base 500, the valve base 500 is opened with a connecting hole 510, the first heat dissipation hole 211 is connected with the connecting hole 510, when the valve leaf 300 is in an open state, the valve leaf 300 opens the connecting hole 510, the electrical chamber 120 can be connected with the fan chamber 110 through the first heat dissipation hole 211 and the connecting hole 510 in sequence; when the valve leaf 300 is in a closed state, the valve leaf 300 blocks the connecting hole 510, isolates the connecting hole 510 from the fan chamber 110, and thereby isolates the electrical chamber 120 from the fan chamber 110.

[0044] like Figures 4 to 6 As shown, in another embodiment of the utility model, the partition assembly 200 includes a partition body 210 and a protective box 220, a first heat dissipation hole 211 is opened on the partition body 210, the protective box 220 is installed on the partition body 210 and corresponds to the position of the first heat dissipation hole 211, and a accommodating space 221 is formed in the protective box 220, and the accommodating space 221 is used to accommodate the inductor 400. For the air conditioner outdoor unit with a three-phase power supply, a plurality of inductors are generally included to improve the grid power supply and reduce interference to the air conditioner controller. The inductor 400 also generates heat during operation. The first heat dissipation hole 211 is connected to the accommodating space 221, and the second heat dissipation hole 222 is provided on the protective box 220. One end of the second heat dissipation hole 222 is connected to the accommodating space 221, and the other end can be connected to the fan chamber 110. The valve leaf 300 is provided on the protective box 220. When the valve leaf 300 is in a closed state, the valve leaf 300 blocks the second heat dissipation hole 222 to isolate the accommodating space 221 from the fan chamber 110. When the valve leaf 300 is in an open state, the valve leaf 300 opens the second heat dissipation hole 222 to connect the fan chamber 110 with the accommodating space 221. By providing the protective box 220, the reactor 400 can have an independent installation position. In addition, when the heat is dissipated in the electrical chamber 120 through the first heat dissipation hole 211, the heat of the reactor 400 can also be simultaneously extracted from the accommodating space 221.

[0045] like Figure 5 , Figure 6 and Figure 8 As shown, the embodiment of the utility model also includes a valve base 500, which is arranged on the protective box 220, and the valve blade 300 is located on the side of the valve base 500 away from the second heat dissipation hole 222. The upper end of the valve blade 300 is hinged to the valve base 500, and the valve base 500 is provided with a connecting hole 510, and the second heat dissipation hole 222 is connected to the connecting hole 510. When the valve blade 300 is in an open state, the valve blade 300 opens the connecting hole 510, and the electrical chamber 120 is connected to the fan chamber 110 through the first heat dissipation hole 211, the accommodating space 221, the second heat dissipation hole 222 and the connecting hole 510 in sequence; when the valve blade 300 is in a closed state, the valve blade 300 blocks the connecting hole 510, thereby isolating the fan chamber 110 from the accommodating space 221, that is, isolating the fan chamber 110 from the electrical chamber 120.

[0046] like Figure 8As shown, in the embodiment of the utility model, a buckle 520 is provided on the valve base 500, and the valve base 500 is connected to the partition assembly 200 via the buckle 520. When the valve base 500 is provided on the partition body 210, the buckle 520 can be buckled at the position of the first heat dissipation hole 211; when the valve base 500 is provided on the protective box 220, the buckle 520 can be buckled at the position of the second heat dissipation hole 222.

[0047] In addition, if Figure 8 As described above, the valve base 500 in the embodiment of the utility model is also provided with a limiting column 530, and a limiting hole is provided on the partition body 210 or the valve base 500 connected to the valve base 500. During installation, the limiting column of the valve base 500 can be inserted into the limiting hole first, and then the buckle 520 can be buckled into the corresponding first heat dissipation hole 211 or the second heat dissipation hole 222.

[0048] like Figure 3 and Figure 6 As described above, in the embodiment of the present invention, a first sealing gasket 540 is disposed between the valve base 500 and the partition assembly 200. The first sealing gasket 540 extends along the circumference of the valve base 500. The first sealing gasket 540 can avoid the connecting hole 510 of the valve base 500. Figure 3 As shown, when the valve seat 500 is disposed on the partition body 210, the first sealing gasket 540 is pressed tightly between the valve seat 500 and the partition body 210 to play a sealing role; Figure 6 As shown, when the valve base 500 is disposed on the protection box 220, the first sealing gasket 540 is pressed tightly between the valve base 500 and the protection box 220, and the first sealing gasket 540 plays a sealing role.

[0049] like Figure 6 As shown, in the embodiment of the utility model, a second sealing gasket 550 is provided on the side of the valve base 500 facing the valve blade 300, and the second sealing gasket 550 extends along the circumference of the valve base 500. When the valve blade 300 is switched to a closed state, the second sealing gasket 550 is squeezed between the valve blade 300 and the valve base 500. The second sealing gasket 550 plays a sealing role and can avoid the connecting hole 510 of the valve base 500.

[0050] like Figure 7As described, in the embodiment of the utility model, the lower end of the valve blade 300 is provided with a magnetic member 310, and the valve base 500 is made of a material that can be adsorbed by the magnetic member 310. The magnetic member 310 can be a permanent magnet or an electromagnet, and the valve base 500 can be a carbon steel sheet metal. Through magnetic adsorption, the valve blade 300 and the valve base 500 can be more tightly sealed. Of course, when negative pressure is formed in the fan chamber 110, the sum of the gravity of the valve blade 300 and the magnetic attraction force needs to be configured to be overcome by the above-mentioned negative pressure, so as to avoid the problem of the valve blade 300 not opening smoothly.

[0051] The partition assembly 200 in the embodiment of the utility model is provided with a filter (not shown in the figure) at the position of the first heat dissipation hole 211. The filter can be located at one end of the first heat dissipation hole 211 close to the electrical chamber 120. The filter can filter the gas sent out of the electrical chamber 120.

[0052] like Figure 3 and Figure 6 As shown, in the embodiment of the present utility model, two first heat dissipation holes 211 are provided, and the two first heat dissipation holes 211 are arranged in the vertical direction. Two second heat dissipation holes 222 are provided, and the two second heat dissipation holes 222 correspond to the two first heat dissipation holes 211 respectively. The axial direction of the second heat dissipation hole 222 is parallel to the axial direction of the fan blade 130, which can prevent the valve blade 300 from interfering with the fan blade 130 when flipping.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
