Description

Technical Field

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

[0002] In the prior art, such as Figure 1 and Figure 2 As shown, a wind-blocking plate 103' is provided in the casing of the air-conditioning outdoor unit, and the wind-blocking plate 103' divides the space in the casing into two chambers, one of which is the heat exchange chamber 101', in which the heat exchanger 500' and the fan 200' are arranged, and the heat exchanger 500' is used for heat exchange between the refrigerant and the gas in the air-conditioning outdoor unit; the fan 200' is used to drive the fan blades 400' to discharge the gas in the heat exchange chamber 100' from the air outlet mesh cover on the front panel of the casing, thereby accelerating the gas flow in the air-conditioning outdoor unit and improving the heat exchange efficiency of the air-conditioning outdoor unit; the other chamber is the compressor chamber 102', in which the compressor 600' and the electronic control box are arranged, and the compressor 600' is used to compress the refrigerant, and the electronic control box is used to control the compressor 600' and the fan 200'.

[0003] In the prior art, the volume of the outdoor unit of the air conditioner is relatively large, and the space occupied is relatively large, while at the same time, the space utilization rate inside the casing is relatively low. Utility Model Content

[0004] The purpose of the utility model is to provide an air conditioner outdoor unit to solve the technical problems in the prior art that the air conditioner outdoor unit is large in size and has a relatively low internal space utilization rate.

[0005] The utility model provides an air-conditioning outdoor unit, including a casing, the casing including a front panel, the front panel including a panel portion, a guide ring portion and an air outlet mesh cover portion, the three being integrated, and the guide ring portion protrudes outward from the panel portion, and the air outlet mesh cover portion is arranged at the air outlet end of the guide ring portion; a fan is arranged in the casing, the output shaft of the fan is coaxially fixed with a hub, and the hub is fixedly installed with a fan blade; the casing also includes a rear wall plate arranged opposite to the front panel, a heat exchange cavity is formed between the panel portion and the rear wall plate, the heat exchanger of the air-conditioning outdoor unit is arranged in the heat exchange cavity, and the ratio of the width of the heat exchange cavity in the front-to-back direction to its length in the left-to-right direction is less than or equal to 0.4; along the axial direction, the tip of the fan blade is located in the heat exchange cavity, and the tail end is located in the guide ring 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 heat exchange chamber with a relatively small ratio of width to length. Compared with the prior art, when the length of the air-conditioning outdoor unit remains unchanged, the distance between the panel portion and the rear wall panel of the air-conditioning outdoor unit provided by the present invention is relatively small, or in other words, the thickness of the main body of the air-conditioning outdoor unit provided by the present invention along the front-to-back direction is relatively small. Therefore, the overall size of the air-conditioning outdoor unit provided by the present invention is relatively small, that is, the volume is relatively small, and the space occupied is also relatively small.

[0008] In order to adapt to the thinning heat exchange chamber, the air conditioner outdoor unit provided by the present invention sets a part of the fan blade in the heat exchange chamber, and the other part is set in the guide ring part. Such a setting can not only make full use of the space in the heat exchange chamber and the guide ring part, improve the compactness of the internal structure of the casing, the rationality of space utilization and the utilization rate of space, but also, the part where the blade tip is located can continue to play the role of accelerating the flow of gas in the heat exchange chamber and guiding the flow in the heat exchange chamber, and the part where the tail end of the fan blade is located can better play the role of guiding the flow in the guide ring part, so that the fan blade can more effectively guide the gas in the heat exchange chamber to the guide ring part, and finally blow it out from the air outlet mesh cover part, ensuring the air output and heat exchange efficiency. In addition, the blade tip of the fan blade is located in the heat exchange chamber, and its size is not affected by the guide ring part, that is, the blade tip of the fan blade can be farther away from the axis of the fan blade, so that the fan blade can be larger, thereby further accelerating the flow of gas in the heat exchange chamber.

[0009] 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.

[0010] Furthermore, the interior of the casing is an integrated cavity, which forms the heat exchange cavity, and the ratio of the width of the heat exchange cavity in the front-to-back direction to its length in the left-to-right direction is less than 0.3; along the left-to-right direction, the heat exchanger and the fan are located on one side of the integrated cavity, and the compressor of the air conditioner outdoor unit is located on the other side of the integrated cavity.

[0011] This technical solution eliminates the conventional windshield panels inside the casing, merging the heat exchange chamber (where the heat exchanger is located) and the compressor chamber (where the compressor is located) into one. This creates a single, integrated chamber within the casing, which also serves as the heat exchange chamber. This further increases the length of the heat exchange chamber, further reducing the width-to-length ratio, and increasing its volume. As the volume of the heat exchange chamber increases, the fan and impellers carry more air, reducing noise and improving sound quality during operation of the air conditioner's outdoor unit.

[0012] In addition, the wind-blocking vertical plate has been removed, and the setting of the compressor, etc. is no longer restricted by it, so that the installation space inside the air-conditioning outdoor unit can be utilized to the maximum extent. At the same time, the heat dissipation on the side where the compressor, etc. are located can also be accelerated, thereby improving the stability of the operation of the air-conditioning outdoor unit.

[0013] Furthermore, the ratio of the heat exchange cavity's width in the front-to-back direction to its length in the left-to-right direction is greater than 0.2. This technical solution prevents the thickness of the air conditioner's outdoor unit from being too thin, effectively ensuring that the heat exchange cavity has sufficient volume, allowing the fan and blades to carry sufficient airflow, ensuring effective heat exchange in the heat exchanger and good sound quality during operation of the air conditioner's outdoor unit.

[0014] Furthermore, the protrusion length H of the guide ring relative to the outer surface of the panel portion is in the range of 70 mm to 80 mm. Under this technical solution, the outward protrusion length of the guide ring portion is relatively appropriate, ensuring sufficient space to accommodate the fan blades and a sufficient distance between the tail end and the panel portion, while not being too long to prevent the timely discharge of the air guided by the fan blades, and also not making the appearance of the outdoor unit look unobtrusive.

[0015] Furthermore, the distance X1 between the blade tip and the panel portion ranges from 70mm to 85mm, and the distance E1 from the air outlet mesh portion ranges from 140mm to 165mm. With this technical solution, the portion of the blade located within the heat exchange chamber is relatively large, effectively improving the flow efficiency of the gas within the heat exchange chamber.

[0016] Furthermore, the distance X2 between the tail wing end and the panel portion is in the range of 44mm to 54mm, and the distance E2 between the tail wing end and the air outlet mesh cover portion is in the range of 20mm to 30mm. Under this technical solution, firstly, the tail wing end of the fan blade is relatively far away from the panel portion, so the gas from the tip of the fan blade can be directly guided into the guide ring portion, which is beneficial to increase the air output of the air conditioner outdoor unit, and further improve the gas flow efficiency and heat exchange efficiency; secondly, the distance between the tail wing 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; the distance within this distance range will not be too small to cause the discharged air flow to be relatively rapid and chaotic, so the air outlet effect is also taken into account.

[0017] Furthermore, the protruding length H of the guide ring portion relative to the outer side surface of the panel portion is 75 mm; the distance X1 between the tip of the blade and the panel portion is 78.5 mm, and the distance E1 from the air outlet mesh cover portion is 153.5 mm; the distance X2 between the tail wing end and the panel portion is 49 mm, and the distance E2 from the air outlet mesh cover portion is 25 mm.

[0018] Furthermore, the distance D between the tail fin end and the inner surface of the guide ring portion ranges from 6 to 10 mm; the distance between the blade tip and the axis of the blade is d1, and the distance between the tail fin end and the axis of the blade is d2, where 0 mm < d1 - d2 ≤ 2 mm. With this technical solution, the radius of the blade at the tip is larger than that at the tail fin end, thereby further accelerating the flow of gas within the heat exchange chamber and ensuring the effective guidance of the airflow.

[0019] Furthermore, the distance D between the tail wing end and the inner side surface of the guide ring portion is 8 mm, and d1-d2=0.9 mm.

[0020] 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.

[0021] Furthermore, along the axial direction, a portion of the hub is located within the guide ring portion, and another portion is located inside the panel portion, and the ratio of the length of the hub within the guide ring portion to the length of the guide ring portion is less than 2 / 3. Under this technical solution, a portion of the hub extends into the guide ring portion, indicating that the portion of the fan blades mounted on the hub located within the guide ring portion is not too small, thereby ensuring the airflow guidance effect; and the ratio of the length of the hub within the guide ring portion to the length of the guide ring portion is less than 2 / 3, indicating that the length of the hub within the guide ring portion is not too long, and the space occupied is not too large, thereby being able to control wind resistance within a relatively small range, thereby ensuring air output.

[0022] 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.

[0023] 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.

[0024] Furthermore, the electric control box of the air conditioner outdoor unit is fixedly mounted on the side panel of the casing and is located on the same side of the integrated cavity as the compressor. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 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.

[0041] This embodiment provides an air conditioner outdoor unit, such as Figures 3 to 8 As shown, the air conditioner outdoor unit includes a casing, which includes a front panel 100. The front panel 100 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. The air outlet mesh cover portion 130 is arranged at the air outlet end of the guide ring portion 120; a fan 200 is arranged in the casing, and the output shaft of the fan 200 is coaxially fixed with a hub 300, and the hub 300 is fixedly installed with a fan blade 400; the casing also includes a rear wall panel 180 arranged opposite to the front panel 100, a heat exchange cavity 101 is formed between the panel portion 110 and the rear wall panel 180, and the heat exchanger 500 of the air conditioner outdoor unit is arranged in the heat exchange cavity 101, and the ratio of the width of the heat exchange cavity 101 along the front-to-back direction to the length thereof along the left-to-right direction is less than or equal to 0.4; along the axial direction, the blade tip 420 of the fan blade 400 is located in the heat exchange cavity 101, and the tail wing end 410 is located in the guide ring portion 120.

[0042] The air-conditioning outdoor unit provided in this embodiment has a relatively small ratio of the width to the length of its heat exchange chamber 101. Compared with the prior art, when the length of the air-conditioning outdoor unit remains unchanged, the distance between the panel portion 110 and the rear wall panel 180 of the air-conditioning outdoor unit provided in this embodiment is relatively small. The thickness of the main body of the air-conditioning outdoor unit provided by the present invention along the front-to-back direction is relatively small. Therefore, the overall size of the air-conditioning outdoor unit provided by the present invention is relatively small, that is, the volume is relatively small, and the space occupied is also relatively small.

[0043] In order to adapt to the thinning heat exchange chamber 101, the air conditioner outdoor unit provided by the present invention arranges a part of the fan blade 400 in the heat exchange chamber 101, and the other part is arranged in the guide ring part 120. Such an arrangement can not only make full use of the space in the heat exchange chamber 101 and the guide ring part 120, but also improve the compactness of the internal structure of the casing, the rationality of space utilization and the utilization rate of space. Moreover, the part where the tip end 420 of the fan blade 400 is located can continue to play the role of accelerating the flow of gas in the heat exchange chamber 101 and guiding the flow, and the part where the tail end 410 of the fan blade 400 is located can better play the guiding role in the guide ring part 120, so that the fan blade 400 can more effectively guide the gas in the heat exchange chamber 101 to the guide ring part 120, and finally blow it out from the air outlet mesh cover part 130, thereby ensuring the air output and heat exchange efficiency. Furthermore, the blade tip 420 of the fan blade 400 is located within the heat exchange chamber 101, and its size is not affected by the guide ring portion 120. That is, the blade tip 420 of the fan blade 400 can be further away from the axis of the fan blade 400, so that the fan blade 400 can be larger, thereby further accelerating the flow of gas within the heat exchange chamber 101. Of course, in other embodiments of the present application, the fan blade 400 can also be completely located within the heat exchange chamber 101 and only be coaxially arranged with the guide ring portion 120.

[0044] In addition, the panel portion 110, the guide ring portion 120 and the air outlet mesh cover portion 130 of the front panel 100 are integrated into one, so that the integrity of the front panel 100 is better, 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.

[0045] Specifically, in this embodiment, Figure 5 and Figure 7 As shown, the interior of the housing is a one-piece cavity, forming a heat exchange cavity 101. The ratio of the width of the heat exchange cavity 101 in the front-to-back direction to its length in the left-to-right direction is less than 0.3. Along the left-to-right direction, the heat exchanger 500 and fan 200 are located on one side of the one-piece cavity, while the compressor 600 of the air conditioner outdoor unit is located on the other side. This configuration eliminates the conventional windshield panels within the housing, merging the heat exchange cavity and the compressor cavity, as is conventional practice. As a result, the interior of the housing becomes a single, integrated cavity, which also serves as the heat exchange cavity 101. This further increases the length of the heat exchange cavity 101, further reducing its width-to-length ratio and increasing its volume. As the volume of the heat exchange cavity 101 increases, the air volume carried by the fan 200 and impellers 400 increases, reducing noise and improving the sound quality of the outdoor unit during operation.

[0046] In addition, the wind-blocking plate is removed, and the arrangement of the compressor 600 and the like is no longer restricted by it, thereby making it possible to maximize the use of the installation space inside the air-conditioning outdoor unit. At the same time, it can also accelerate the heat dissipation on the side where the compressor 600 and the like are located, thereby improving the stability of the operation of the air-conditioning outdoor unit.

[0047] Specifically, in this embodiment, the ratio of the width of the heat exchange chamber 101 in the front-to-back direction to its length in the left-to-right direction is greater than 0.2. This configuration prevents the thickness of the air conditioner's main body from being too thin, effectively ensuring that the heat exchange chamber 101 has sufficient volume, allowing the fan 200 and blades 400 to carry sufficient airflow, ensuring effective heat exchange in the heat exchanger 500 and good sound quality during operation of the air conditioner.

[0048] like Figure 2 As shown, the cross section of the heat exchange cavity of the air conditioner outdoor unit in the prior art can be regarded as a trapezoid, and its average length is taken as the length L1 of the heat exchange cavity, then L1 = (C1 + C2) / 2, the cross-sectional area S1 = L1 * W1, and the ratio of its width to length is W1 / L1. In this embodiment, as Figure 7 As shown, the cross-sectional area of ​​the heat exchange cavity 101 is S2=L2*W2. Obviously, L2>L1, W2<W1, so W1 / L1>W2 / L2, that is, the ratio of the width to the length of the heat exchange cavity 101 of the air-conditioning outdoor unit in this embodiment is smaller, and by controlling the width of the heat exchange cavity 101 represented by W2, S2>S1 can be made, thereby ensuring that the air-conditioning outdoor unit has a sufficiently large heat exchange cavity 101.

[0049] Specifically, in this embodiment, Figure 9 As shown, the protrusion length H of the guide ring portion 120 relative to the outer surface of the panel portion 110 ranges from 70 mm to 80 mm. In this configuration, the outward protrusion length of the guide ring portion 120 is suitable, ensuring sufficient space to accommodate the fan blades 400 and a sufficient distance between the tail end 410 and the panel portion 110, while not being too long to prevent the air guided by the fan blades 400 from being discharged in a timely manner, and the appearance of the outdoor unit is not too abrupt.

[0050] In this embodiment, Figure 7 As shown, the distance X1 between the blade tip 420 and the panel portion 110 ranges from 70 mm to 85 mm, and the distance E1 from the outlet grille portion 130 ranges from 140 mm to 165 mm. With this configuration, the portion of the blade 400 located within the heat exchange chamber 101 is relatively large, effectively improving the flow efficiency of the gas within the heat exchange chamber 101.

[0051] In this embodiment, Figure 9As shown, the distance X2 between the tail wing end 410 and the panel portion 110 ranges from 44 mm to 54 mm, and the distance E2 between the tail wing end 410 and the air outlet grille portion 130 ranges from 20 mm to 30 mm. Under this arrangement, firstly, the tail wing end 410 of the fan blade 400 is relatively far from the panel portion 110, so that the air from the tip 420 of the fan blade 400 can be directly directed into the guide ring portion 120, thereby increasing the air output of the air conditioner outdoor unit, thereby improving the air flow efficiency and heat exchange efficiency. Secondly, the distance between the tail wing end 410 of the fan blade 400 and the air outlet grille portion 130 is relatively suitable, and the distance between the two is not too large. Therefore, after the air guided by the fan blade 400 continues to flow forward for a short distance in the guide ring portion 120, it can be discharged from the air outlet grille portion 130 in a timely manner. The distance within this range is not too small to cause the discharged air flow to be too fast or chaotic, so the air outlet effect is also taken into account.

[0052] More specifically, in this embodiment, the protruding length H of the guide ring portion 120 relative to the outer side surface of the panel portion 110 can be 75 mm; the distance X1 between the blade tip 420 and the panel portion 110 can be 78.5 mm, and the distance E1 from the air outlet mesh cover portion 130 can be 153.5 mm; the distance X2 between the tail wing end 410 and the panel portion 110 can be 49 mm, and the distance E2 from the air outlet mesh cover portion 130 can be 25 mm.

[0053] Specifically, in this embodiment, Figure 9 As shown, the distance D between the tail fin end 410 and the inner side surface of the guide ring portion 120 ranges from 6 to 10 mm. In this arrangement, the distance between the tail fin end 410 and the inner side surface of the guide ring portion 120 is relatively small, effectively preventing gas backflow, but not too small to ensure smooth installation of the fan blade 400 and effectively prevent collision between the tail fin end 410 of the fan blade 400 and the guide ring portion 120.

[0054] In this embodiment, the distance between the blade tip 420 and the axis of the blade 400 is d1, and the distance between the trailing fin end 410 and the axis of the blade 400 is d2, where 0 mm < d1 - d2 ≤ 2 mm. In this configuration, the radius of the blade 400 at the blade tip 420 is larger than that at the trailing fin end 410, thereby further accelerating the flow of gas within the heat exchange chamber 101 and ensuring effective airflow guidance.

[0055] More specifically, in this embodiment, the distance D between the tail fin end 410 and the inner side surface of the guide ring portion 120 is 8 mm, d1-d2=0.9 mm. The value of D is relatively moderate and can better take into account both the effects of avoiding backflow and avoiding collision.

[0056] 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.

[0057] Specifically, in this embodiment, Figure 8 As shown, along the axial direction, a portion of the hub 300 is located within the guide ring portion 120, and another portion is located inside the panel portion 110. Furthermore, 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 less than 2 / 3. In this configuration, a portion of the hub 300 extends into the guide ring portion 120, indicating that the portion of the fan blades 400 mounted on the hub 300 located within the guide ring portion 120 is not too small, thereby ensuring the airflow guidance effect. Furthermore, 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 less than 2 / 3, indicating that the length of the portion of the hub 300 within the guide ring portion 120 is not too long, and the space occupied is not too large, thereby keeping the wind resistance within a relatively small range and ensuring the air output.

[0058] Specifically, in this embodiment, the front panel 100 is a sheet metal component, and the panel portion 110, the air guide ring portion 120, and the air outlet mesh cover 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 100 can also be a plastic component, and the panel portion 110, the air guide ring portion 120, and the air outlet mesh cover portion 130 can be integrally formed through injection molding or other processes. In this case, the front panel 100 is relatively lightweight.

[0059] Specifically, in this embodiment, Figure 5 As shown, the electric control box 700 of the air conditioner outdoor unit is fixedly mounted on the side panel of the housing and is located on the same side of the integrated cavity as the compressor 600. More specifically, in this embodiment, the heat exchanger 500 and fan 200 of the air conditioner outdoor unit are located on the left side of the integrated cavity, while the compressor 600 and the electric control box 700 of the air conditioner outdoor unit are located on the right side of the integrated cavity. The electric control box 700 is disposed on the right side panel 190 of the housing side panel and is fixedly connected to the inner wall of the right side panel 190. Of course, in other embodiments of the present application, the heat exchanger 500 and fan 200 of the air conditioner outdoor unit may also be located on the right side of the integrated cavity, while the compressor 600 and the electric control box 700 are located on the left side of the integrated cavity, and the electric control box 700 is disposed on the left side panel of the housing side panel and is fixedly connected to the inner wall of the left side panel.
