Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air conditioner outdoor unit and an air conditioner. Background Art

[0002] A split-type air conditioner includes an indoor unit and an outdoor unit. The front panel of the outdoor unit is provided with an air outlet mesh cover. The outdoor unit is provided with a heat exchanger, a fan, a compressor, etc. The compressor is used to compress the refrigerant; the heat exchanger is used to exchange heat between the refrigerant and the gas in the outdoor unit; the output shaft of the fan is equipped with a hub, and the hub is equipped with fan blades, which can discharge the gas in the outdoor unit from the air outlet mesh cover, thereby accelerating the gas flow in the outdoor unit and improving the heat exchange efficiency of the outdoor unit.

[0003] However, in the prior art, the air output of the outdoor unit of the air conditioner is relatively small, the heat exchange efficiency is relatively low, and the noise is relatively loud, which affects the user experience. Utility Model Content

[0004] The first purpose of the present utility model is to provide an air-conditioning outdoor unit to solve the technical problems of the air-conditioning outdoor unit in the prior art, that is, the air output volume is relatively small and the noise is relatively large.

[0005] The utility model provides an air-conditioning outdoor unit, comprising a casing and a fan arranged in the casing, the casing comprising a front panel, the front panel comprising a panel portion, a guide ring portion and an air outlet mesh cover portion, the three being integrated, and the guide ring portion protruding outward from the panel portion, the air outlet mesh cover portion being arranged at the air outlet end of the guide ring portion; the output shaft of the fan is coaxially fixed with a hub, and the hub is fixedly mounted with fan blades; along the axial direction, a part of the hub is located in the guide ring portion, and the other part is located on the inner side of the panel portion.

[0006] The air conditioner outdoor unit provided by the utility model can produce the following beneficial effects:

[0007] The air-conditioning outdoor unit provided by the present invention has a portion of the hub moved outward to the guide ring portion. As the hub moves outward, the fan blades also move outward, so that the tail end of the fan blade is closer to the guide ring portion or is located inside the guide ring portion. In this way, after the fan blade guides the gas to its tail end, its tail end can cause the gas to be discharged along the guide ring portion as quickly as possible, thereby increasing the air output. The other portion of the hub is located on the inner side of the panel portion. In this way, the space occupied by the hub in the guide ring portion is relatively small, and the wind resistance generated is also relatively small, which helps to ensure the air output of the air-conditioning outdoor unit. In summary, the air-conditioning outdoor unit provided by the present invention has a relatively large air output, and the gas flow efficiency and the heat exchange efficiency of the air-conditioning outdoor unit are relatively high.

[0008] In addition, if the air output is the same, compared with the air-conditioning outdoor unit in the prior art, the air-conditioning outdoor unit provided by the utility model can control the wind speed of the fan at a lower level, thereby reducing wind noise.

[0009] Furthermore, compared with the air-conditioning outdoor unit in the prior art, the air-conditioning outdoor unit provided by the utility model has the same maximum thickness along the front-to-back direction, and the guide ring portion is arranged to bulge outward relative to the panel portion, which is actually equivalent to reducing the distance between the panel portion of the front panel and the rear wall panel of the casing. The main body thickness or average thickness of the entire air-conditioning outdoor unit is actually reduced, and it is more miniaturized, thereby reducing space occupancy and facilitating transportation and high-altitude operations.

[0010] In addition, the panel part, the guide ring part and the air outlet mesh cover part of the front panel are integrated into one, which makes the front panel more integrated, thereby having higher structural strength, better appearance consistency and more beautiful appearance. Moreover, the integrated setting of the three can also be assembled as a whole, thereby greatly simplifying the assembly process and improving assembly efficiency; when disassembling, it can also be disassembled as a whole.

[0011] Furthermore, the ratio of the length of the hub portion within the guide ring to the length of the guide ring is less than 2 / 3. With this technical solution, the hub portion within the guide ring is not excessively long, does not occupy too much space, and can keep wind resistance within a relatively small range, thereby ensuring air output.

[0012] Furthermore, a protruding length H of the guide ring portion relative to the outer side surface of the panel portion is 43 mm to 76 mm; and a distance B between the hub and the air outlet mesh cover portion is 30 mm to 55 mm.

[0013] With this technical solution, the outward protrusion of the guide ring is appropriately long, ensuring sufficient space for the hub and its blades while also minimizing the appearance of the air conditioner outdoor unit. The distance between the hub and the air outlet grille is also optimal, ensuring a suitable distance between the tail end of the hub's blades and the grille, facilitating the timely discharge of air guided by the blades.

[0014] Furthermore, the protruding length H of the guide ring portion relative to the outer side surface of the panel portion is 55 mm; the distance B between the hub and the air outlet mesh cover portion is 49 mm; the length L of the hub within the guide ring portion is 1 mm, or the ratio of the length of the portion of the hub within the guide ring portion to the length of the guide ring portion is 1 / 55; the ratio of the diameter of the hub to the inner diameter of the guide ring portion is 0.22.

[0015] Furthermore, the tail wing end of the fan blade is arranged in the guide ring portion, and the distance X between the tail wing end and the outer side surface of the panel portion is 24mm~38mm, the distance E between the tail wing end and the air outlet mesh cover portion is 16mm~28mm, and the distance D between the tail wing end and the inner side surface of the guide ring portion is 3mm~15mm.

[0016] Under this technical solution, firstly, the tail end of the fan blade is arranged in the guide ring portion and is relatively far away from the panel portion. Therefore, the tail end of the fan blade can directly guide the gas from the blade tip into the guide ring portion, thereby increasing the air output of the air conditioner outdoor unit, thereby improving the gas flow efficiency and the heat exchange efficiency of the air conditioner outdoor unit. Secondly, the distance between the tail end of the fan blade and the air outlet mesh cover portion is relatively appropriate, and the distance between the two is not too large. Therefore, after the gas guided by the fan blade continues to flow forward for a short distance in the guide ring portion, it can be discharged from the air outlet mesh cover portion in a timely manner. In addition, the distance within this range is not too small to cause the discharged air flow to be relatively rapid and chaotic, so the air outlet effect is also taken into account. As for the distance between the tail end and the inner side surface of the guide ring portion, the above distances are relatively small, so that gas backflow can be effectively avoided, but not too small, so that the fan blade can be installed smoothly and the collision between the tail end of the fan blade and the guide ring portion can be effectively avoided.

[0017] Furthermore, the distance X between the tail wing end and the outer side surface of the panel portion is 49 mm, the distance E between the tail wing end and the air outlet mesh cover portion is 25 mm, and the distance D between the tail wing end and the inner side surface of the guide ring portion is 8 mm.

[0018] Furthermore, the pressure surface of the fan blade facing the air outlet mesh cover is concavely arranged inside the housing. Such an arrangement is beneficial for the fan blade to guide the airflow to be discharged forward.

[0019] Furthermore, a motor frame is provided in the casing, and the fan is provided on the motor frame; or, the fan is provided on the air outlet mesh cover.

[0020] Furthermore, the front panel is a sheet metal part, and the panel part, the guide ring part and the air outlet mesh cover part are stamped as one piece; or, the front panel is a plastic part, and the panel part, the guide ring part and the air outlet mesh cover part are molded as one piece.

[0021] Under this technical solution, if the front panel is a sheet metal part, the panel part, the guide ring part and the air outlet mesh cover part can be manufactured through integrated stamping and bending processes, and the structural strength of the sheet metal part is relatively high; if the front panel is a plastic part, the panel part, the guide ring part and the air outlet mesh cover part can be integrally formed through injection molding and other processes. At this time, the weight of the front panel is relatively light.

[0022] Furthermore, the air inlet end of the guide ring portion transitions to the panel portion in an arc shape. Under this technical solution, the air inlet and air inlet angle of the guide ring portion are both relatively large, and the wind resistance of the arc transition portion is relatively small, which facilitates the smooth entry of air in the air conditioner outdoor unit into the guide ring portion.

[0023] The second purpose of the present invention is to provide an air conditioner to solve the technical problems in the prior art that the air outlet volume of the outdoor unit of the air conditioner is relatively small and the noise is relatively loud.

[0024] The air conditioner provided by the present invention comprises the above-mentioned outdoor unit and an indoor unit, wherein the outdoor unit and the indoor unit are connected via a refrigerant pipe. The air conditioner has all the advantages of the above-mentioned outdoor unit, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] This embodiment provides an air conditioner outdoor unit, such as Figure 1 、 Figure 2 and Figure 4 As shown, the air-conditioning outdoor unit includes a casing and a fan 200 arranged in the casing, the casing includes a front panel, the front panel includes a panel portion 110, a guide ring portion 120 and an air outlet mesh cover portion 130, the three are integrated, and the guide ring portion 120 protrudes outward from the panel portion 110, and the air outlet mesh cover portion 130 is arranged at the air outlet end of the guide ring portion 120; the output shaft of the fan 200 is coaxially fixed with a hub 300, and the hub 300 is fixedly mounted with a fan blade 400; along the axial direction, a part of the hub 300 is located in the guide ring portion 120, and the other part is located on the inner side of the panel portion 110.

[0035] In the air-conditioning outdoor unit provided by this embodiment, a portion of the hub 300 moves outward into the guide ring portion 120. As the hub 300 moves outward, the fan blade 400 also moves outward, so that the tail end 410 (the end with the largest diameter of the trailing edge) of the fan blade 400 is relatively close to the guide ring portion 120 or is located inside the guide ring portion 120. In this way, after the fan blade 400 guides the gas to its tail end 410, its tail end 410 can cause the gas to be discharged along the guide ring portion 120 as quickly as possible, thereby increasing the air output. Another portion of the hub 300 is located on the inner side of the panel portion 110. In this way, the hub 300 occupies a relatively small space in the guide ring portion 120, and the wind resistance generated is also relatively small, which helps to ensure the air output of the air-conditioning outdoor unit. In summary, the air-conditioning outdoor unit provided by this embodiment has a relatively large air output, and the gas flow efficiency and heat exchange efficiency of the air-conditioning outdoor unit are relatively high.

[0036] In addition, if the air output volume is the same, compared with the air-conditioning outdoor unit in the prior art, the air-conditioning outdoor unit provided in this embodiment can control the wind speed of the fan 200 at a lower level, thereby reducing wind noise.

[0037] Furthermore, compared with the air-conditioning outdoor unit in the prior art, when the maximum thickness of the air-conditioning outdoor unit along the front-to-back direction is consistent, the air-conditioning outdoor unit provided in this embodiment has the guide ring portion 120 protruding relative to the panel portion 110, which is actually equivalent to reducing the distance between the panel portion 110 of the front panel and the rear wall panel of the casing. The main body thickness or average thickness of the entire air-conditioning outdoor unit is actually reduced, and it is more miniaturized, thereby reducing space occupancy and facilitating transportation and high-altitude operations.

[0038] In addition, the panel portion 110, the guide ring portion 120 and the air outlet mesh cover portion 130 of the front panel are integrated into one, which makes the front panel more integrated, thereby having higher structural strength, better appearance consistency and more beautiful appearance. Moreover, the integrated arrangement of the three can also be assembled in an integrated manner, thereby greatly simplifying the assembly process and improving assembly efficiency; when disassembling, it can also be disassembled in an integrated manner.

[0039] Specifically, in this embodiment, Figure 3 and Figure 4 As shown, the ratio of the length of the hub 300 within the guide ring portion 120 to the length of the guide ring portion 120 is less than 2 / 3. With this configuration, the length of the hub 300 within the guide ring portion 120 is not excessive, the space occupied is not excessive, and wind resistance can be kept within a relatively small range, thereby ensuring air output.

[0040] Specifically, in this embodiment, continue as Figure 3 and Figure 4As shown, the protruding length H of the guide ring portion 120 relative to the outer side surface of the panel portion 110 is 43mm to 76mm; the distance B between the hub 300 and the air outlet mesh portion 130 is 30mm to 55mm. The length H of the guide ring portion 120 includes part of the thickness of the air outlet mesh portion 130, because in this embodiment, a portion of the air outlet mesh portion 130 along the axial direction is located inside the guide ring portion 120, and the other portion is located outside the guide ring portion 120. For example, the thickness of the air outlet mesh portion 130 is 10mm, 5mm is inside the guide ring portion 120, and 5mm is outside the guide ring portion 120. At this time, if H is 55mm, the distance from the panel portion 110 to the inner side surface of the air outlet mesh portion 130 is 50mm. Furthermore, the protruding length H of the guide ring portion 120 relative to the outer side surface of the panel portion 110 can be 55 mm; the distance B between the hub 300 and the air outlet mesh cover portion 130 can be 49 mm; in this case, the length L of the hub 300 within the guide ring portion 120 is 1 mm, or the ratio of the length of the portion of the hub 300 within the guide ring portion 120 to the length of the guide ring portion 120 is 1 / 55; the ratio of the diameter of the hub 300 to the inner diameter of the guide ring portion 120 is 0.22. For example, the diameter of the hub 300 is 100 mm, and the inner diameter of the guide ring portion 120 is 456 mm. Under this configuration, the outward protrusion length of the guide ring portion 120 is relatively appropriate, ensuring sufficient space to accommodate the hub 300 and the fan blades 400 on the hub 300, while also reducing the appearance of the air conditioner outdoor unit from being too obtrusive. The distance between the hub 300 and the air outlet mesh portion 130 is also relatively suitable, and thus the distance between the tail end 410 of the fan blade 400 on the hub 300 and the air outlet mesh portion 130 is also relatively suitable, which facilitates the timely discharge of the air guided by the fan blade 400. In addition, the hub 300 occupies relatively little space within the guide ring portion 120, both axially and radially, resulting in relatively low wind resistance, which helps to ensure the air output.

[0041] Specifically, in this embodiment, Figure 2 and Figure 4 As shown, the tail end 410 of the fan blade 400 is disposed within the guide ring portion 120, and the distance X between the tail end 410 and the outer side surface of the panel portion 110 is 24 mm to 38 mm, the distance E between the tail end 410 and the air outlet mesh portion 130 is 16 mm to 28 mm, and the distance D between the tail end 410 and the inner side surface of the guide ring portion 120 is 3 mm to 15 mm. Furthermore, the distance X between the tail end 410 and the outer side surface of the panel portion 110 can be 30 mm, the distance E between the tail end 410 and the air outlet mesh portion 130 can be 20 mm, and the distance D between the tail end 410 and the inner side surface of the guide ring portion 120 can be 8 mm.

[0042] Under the above arrangement, firstly, the tail end 410 of the fan blade 400 is disposed within the guide ring portion 120 and is relatively far from the panel portion 110. Therefore, the tail end 410 of the fan blade 400 can directly guide the gas from the blade tip 420 into the guide ring portion 120, thereby facilitating an increase in the air output of the air conditioner outdoor unit, thereby improving the gas flow efficiency and the heat exchange efficiency of the air conditioner outdoor unit. Furthermore, the distance between the tail end 410 of the fan blade 400 and the air outlet mesh portion 130 is relatively suitable, and the distance between the two is not too large. Therefore, after the gas guided by the fan blade 400 continues to flow forward for a short distance within the guide ring portion 120, it can be promptly discharged from the air outlet mesh portion 130. Furthermore, the distance within this range is not too small to cause the discharged airflow to be too rapid or chaotic, thus also taking into account the air outlet effect. As for the distance between the tail wing end 410 and the inner side surface of the guide ring portion 120, the above distance is relatively small, so it can effectively avoid gas backflow, but it is not too small, so it can ensure the smooth installation of the fan blade 400 and effectively avoid the collision between the tail wing end 410 of the fan blade 400 and the guide ring portion 120.

[0043] Specifically, in this embodiment, Figure 2 and Figure 4 As shown, the blade tip 420 of the fan blade 400 is arranged in the casing. Such arrangement is conducive to the cooperation between the blade tip 420 and the tail end 410 of the fan blade 400 to guide the gas in the casing into the guide ring part 120.

[0044] Specifically, in this embodiment, the fan blades 400 are arranged to be concave toward the interior of the housing, facing the pressure surface 401 of the air outlet mesh cover 130. This arrangement is beneficial for the fan blades 400 to guide the airflow to be discharged forward.

[0045] Specifically, in this embodiment, a motor rack is provided within the housing, and the fan 200 is disposed on the motor rack. However, it should be noted that in other embodiments of the present application, the placement of the fan 200 is not limited to the motor rack within the housing. For example, the fan 200 may also be disposed on the air outlet grille portion 130.

[0046] Specifically, in this embodiment, the front panel is a sheet metal component, and the panel portion 110, the air guide ring portion 120, and the air outlet mesh portion 130 are manufactured through integrated stamping and bending processes, resulting in a relatively high structural strength of the sheet metal component. Optionally, in other embodiments of the present application, the front panel can also be a plastic component, and the panel portion 110, the air guide ring portion 120, and the air outlet mesh portion 130 can be integrally formed through injection molding or other processes. In this case, the front panel is relatively lightweight.

[0047] Specifically, in this embodiment, the air inlet end of the guide ring portion 120 forms an arc transition with the panel portion 110. With this arrangement, the air inlet opening and air inlet angle of the guide ring portion 120 are both relatively large, and the wind resistance at the arc transition portion is relatively low, which facilitates the smooth entry of air from the air conditioner's outdoor unit into the guide ring portion 120.

[0048] This embodiment also provides an air conditioner, which includes the above-mentioned outdoor unit and an indoor unit, wherein the outdoor unit and the indoor unit are connected via a refrigerant pipe. The air conditioner has all the advantages of the above-mentioned outdoor unit, which will not be repeated here.

[0049] Finally, it should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0050] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
