[0033] The utility model provides a front panel.

[0034] In one embodiment of the present invention, Figures 1 to 4 As shown, the front panel includes:

[0035] A plate body 100, wherein the plate body 100 comprises a first portion 110 corresponding to a fan chamber of the outdoor unit, and the first portion 110 is provided with an air outlet 111;

[0036] An air guide ring 200 is convexly disposed on the inner side of the first portion 110 , and the periphery of the air guide ring 200 is connected to the periphery of the air outlet 111 ; and

[0037] The enclosure portion 300 is disposed around the air guide ring 200 , and the inner periphery of the enclosure portion 300 is in contact with the outer periphery of the air guide ring 200 .

[0038] In the technical solution of the present utility model, since the enclosure 300 is arranged outside the air guide ring 200, and the enclosure 300 is arranged in close contact with the air guide ring 200, the space on the inner side of the front panel located at the outer periphery of the air guide ring 200 is at least partially transformed into a solid structure, which can exclude the air on the inner side of the front panel and the outer periphery of the air guide ring 200 to a certain extent. When the fan is running, the possibility of the air around the air guide ring 200 being disturbed is reduced, and the formation of vortices around the air guide ring 200 can be suppressed to a certain extent, thereby avoiding increasing the power of the motor. At the same time, it is beneficial to reduce the operating noise of the outdoor unit and ensure the working performance of the outdoor unit.

[0039] It can be understood that the fan chamber of the outdoor unit is formed between the chassis and the top cover, and is formed by the partition, the heat exchanger and the first part 110. The plate body 100 is also connected to a first side plate, which is arranged opposite to the partition and located on one side of the fan chamber. The plate body 100 also includes four edge portions 112 arranged on the four sides of the first part 110, wherein the upper edge portion 112 is used to connect with the top cover, the lower edge portion 112 is connected to the chassis, one of the other two edge portions 112 is connected to the partition, and the other is connected to the first side plate, and is arranged opposite to the side of the heat exchanger. The enclosure portion 300 is arranged at the first part 110, which can avoid the above edge portions 112, does not affect the connection between the partition, the top cover and the chassis and the first side plate and the plate body 100, and the side of the heat exchanger can be adaptively inserted between the first side plate and the enclosure portion 300, and the enclosure portion 300 will not interfere with the heat exchanger. A second side plate is also provided on the other side of the partition, and a compressor cavity for accommodating a compressor is formed between the second side plate and the partition.

[0040] In addition, the plate body 100 may further include a second portion 120 for enclosing the press cavity, and the second portion 120 and the first portion 110 may be integrally formed or separately formed. That is, the front panel may be an integral structure having two portions corresponding to the press cavity and the fan cavity, respectively, or the front panel may be formed by combining the two portions after being independently formed.

[0041] In one embodiment, the outer periphery of the enclosure 300 is close to the edge of the first part 110, and on the side away from the first part 110, the surface of the enclosure 300 is close to the end face of the air guide ring 200, so that at least most of the air guide ring 200 is surrounded by the enclosure 300. In this way, the filling effect of the outer peripheral space of the air guide ring 200 can be further improved, thereby further improving the removal effect of the air here, and can effectively inhibit the formation of eddy currents around the air guide ring 200, and effectively reduce the operating noise of the outdoor unit, and ensure the working performance of the outdoor unit. It should be noted that the air guide ring 200 is surrounded by the enclosure, which means that in the axial direction of the air guide ring 200, the height of the air guide ring 200 surrounded by the enclosure accounts for at least 50% of the height of the air guide ring 200 protruding into the fan cavity. According to actual needs, the height ratio can be adaptively adjusted to more than 60%, more than 70%, more than 80%, more than 90%, more than 95%, etc.

[0042] In one embodiment, the outer periphery of at least one side of the enclosure 300 overlaps with the outer periphery of the first portion 110. That is, the axial projection of the enclosure 300 on the first portion 110 overlaps with the outer periphery of the first portion 110 on at least one side, so that the enclosure 300 can effectively fill the space on that side, thereby eliminating the vortex on that side. When the outer periphery of the enclosure 300 overlaps with the outer periphery of the first portion 110 everywhere, the surrounding space of the air guide ring 200 can be effectively filled by the enclosure 300, so that the vortex on the outer periphery of the air guide ring 200 can be eliminated, which is conducive to further improving the working performance of the outdoor unit.

[0043] In one embodiment, on the side away from the first portion 110, the axial distance between the end face of the air guide ring 200 and the surface of the enclosure 300 is less than 5 mm. That is, the height of the air guide ring 200 protruding from the inner side of the first portion 110 of the plate body 100 and the height of the enclosure 300 protruding from the inner side of the first portion 110 of the plate body 100 are substantially equal, so as to ensure the effect of eliminating the vortex while ensuring the air volume of the outdoor unit. It can be understood that if the protruding height of the enclosure 300 is much lower than the protruding height of the air guide ring 200, it is impossible to ensure that the enclosure 300 effectively fills the peripheral space of the air guide ring 200, and the area around the air guide ring 200 is still prone to vortex. If the protruding height of the enclosure 300 is much higher than the protruding height of the air guide ring 200, it will occupy too much space in the fan cavity, affecting the air volume of the outdoor unit. Of course, in other embodiments, if the performance requirements for the outdoor unit are not high, the above axial distance can also be increased to within 10 mm or within 20 mm.

[0044] In one embodiment, the enclosure 300 is integrally formed with the first portion 110. In this way, the production efficiency of the front panel can be improved, thereby improving the manufacturability of the outdoor unit. Further, the air guide ring 200 and the first portion 110 are also integrally formed, that is, the enclosure 300, the air guide ring 200 and the first portion 110 are all integrally formed, so as to further improve the production efficiency of the front panel.

[0045] Specifically, the enclosure 300, the air guide ring 200 and the first portion 110 are integrally formed by injection molding or casting. That is, the front panel can be made of metal material, and the air guide ring 200 and the enclosure 300 are integrally formed in the first portion 110 by casting, and the front panel can also be made of plastic material, and the air guide ring 200 and the enclosure 300 are integrally formed in the first portion 110 by injection molding.

[0046] In particular, if Figure 3 and Figure 4 As shown, when the raised height of the air guide ring 200 is flush with the raised height of the enclosure 300, if the air guide ring 200, the enclosure 300 and the first portion 110 are integrally formed, there will be no obvious dividing line between the three, but it can be understood that the first portion 110 extends rearward from the front side of the plate body 100, the enclosure 300 extends forward from the inside of the fan cavity, and the air guide ring 200 extends radially outward from the inner periphery of the air outlet.

[0047] In one embodiment, the enclosure 300 is independently formed and installed on the first portion 110. In this way, the original production mold of the front panel does not need to be changed, and only the enclosure 300 needs to be additionally produced and then assembled outside the air guide ring 200.

[0048] The air guide ring 200 is formed at the air outlet 111 of the first part 110 by stamping. That is, the front panel is configured as a sheet metal part, which is formed by stamping. The air guide ring 200 and the plate body 100 will be formed together during the stamping process to ensure the production efficiency of the front panel. Of course, in other embodiments, the air guide ring 200 can also be formed independently and then installed at the air outlet 111 of the first part 110.

[0049] Furthermore, the enclosure 300 is configured to be a sound-absorbing material. In this way, the enclosure 300 can effectively absorb noise while filling the space around the air guide ring 200, which is beneficial to improving the working performance of the outdoor unit. Among them, the enclosure 300 is preferably made of foam material and can be fixed to the first portion 110 by bonding. Of course, in other embodiments, the enclosure 300 can also be made of foam material. In addition, it can also be fixed to the first portion 110 by providing a groove in the enclosure 300 and interfering with the convex portion of the first portion 110.

[0050] The utility model also proposes an outdoor unit, which includes a front panel. The specific structure of the front panel refers to the above-mentioned embodiment. Since the outdoor unit adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0051] The utility model also provides an air conditioner, which includes the above-mentioned outdoor unit. Therefore, all the technical solutions of all the above-mentioned embodiments are also adopted, and at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments are possessed, which will not be described one by one here.

[0052] The above description is only an optional embodiment of the present invention, and does not limit the protection scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the protection scope of the present invention.
