Description

Technical Field

[0001] This invention relates to the technical field of air conditioning, and more specifically, to an outdoor unit for an air conditioner. Background Technology

[0002] In existing technologies, such as Figure 1 and Figure 2 As shown, the air conditioner outdoor unit has a baffle plate 103' inside its casing, which divides the space inside the casing into two chambers. One chamber is a heat exchange chamber 101', where a heat exchanger 500' and a fan 200' are located. The heat exchanger 500' is used for heat exchange between the refrigerant and the gas inside the air conditioner outdoor unit. The fan 200' drives the fan blades 400' to discharge the gas in the heat exchange chamber 101' from the air outlet grille on the front panel of the casing, thereby accelerating the gas flow inside the air conditioner outdoor unit and improving the heat exchange efficiency of the air conditioner outdoor unit. The other chamber is a compressor chamber 102', where a compressor 600' and an electrical control box are located. The compressor 600' is used to compress the refrigerant, and the electrical control box is used to control the compressor 600' and the fan 200'.

[0003] In the existing technology, the outdoor unit of an air conditioner is relatively large in size and occupies a lot of space, while the space utilization rate inside the casing is relatively low. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioner outdoor unit to solve the technical problems of large size and low internal space utilization of existing air conditioner outdoor units.

[0005] The present invention provides an air conditioner outdoor unit, comprising a housing, the housing including a front panel, the front panel including a panel portion, a guide ring portion, and an air outlet grille portion, all three being integrally formed, with the guide ring portion protruding outward from the panel portion, and the air outlet grille portion disposed at the air outlet end of the guide ring portion; a fan is disposed inside the housing, the output shaft of the fan being coaxially fixedly provided with a hub, and the hub being fixedly mounted with fan blades; the housing also includes a rear wall panel disposed opposite to the front panel, a heat exchange cavity being formed between the panel portion and the rear wall panel, the heat exchanger of the air conditioner outdoor unit being disposed within the heat exchange cavity, 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 being less than or equal to 0.4; axially, the tip of the fan blade is located within the heat exchange cavity, and the tail end is located within the guide ring portion.

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

[0007] The air conditioner outdoor unit provided by the present invention has a smaller ratio of width to length of heat exchange cavity. Compared with the prior art, with the length of the air conditioner outdoor unit remaining unchanged, the distance between the front panel and the rear wall panel of the air conditioner outdoor unit provided by the present invention is smaller. In other words, the thickness of the main body of the air conditioner outdoor unit provided by the present invention along the front-to-back direction is smaller. Therefore, the overall size of the air conditioner outdoor unit provided by the present invention is smaller, that is, the volume is smaller, and the space occupied is also smaller.

[0008] To accommodate the thinner heat exchange cavity, the air conditioner outdoor unit provided by this invention has one part of the fan blade located inside the heat exchange cavity and the other part located inside the guide ring. This arrangement not only fully utilizes the space within the heat exchange cavity and the guide ring, improving the compactness of the internal structure, the rationality of space utilization, and the efficiency of space utilization, but also allows the fan blade tip to continue accelerating and guiding the gas flow within the heat exchange cavity, while the tail end of the fan blade can better guide the flow within the guide ring. This allows the fan blade to more effectively guide the gas within the heat exchange cavity to the guide ring and ultimately blow it out from the air outlet grille, ensuring airflow and heat exchange efficiency. Furthermore, since the fan blade tip is located inside the heat exchange cavity, its size is not affected by the guide ring; that is, the fan blade tip can be further from the fan blade axis, allowing for a larger fan blade, which further accelerates the gas flow within the heat exchange cavity.

[0009] In addition, the front panel, air guide ring, and air outlet grille are integrated into one unit, which improves the overall integrity of the front panel, resulting in higher structural strength, better appearance consistency, and a more aesthetically pleasing appearance. Moreover, the integrated design allows for one-piece assembly, which greatly simplifies the assembly process and improves assembly efficiency; it also allows for one-piece disassembly.

[0010] Furthermore, the interior of the housing is an integral cavity, which forms the heat exchange cavity. 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. In the left-to-right direction, the heat exchanger and the fan are located on one side of the integral cavity, and the compressor of the outdoor unit of the air conditioner is located on the other side of the integral cavity.

[0011] In this technical solution, the conventionally installed air-insulating baffles inside the casing are eliminated, merging the heat exchange chamber (where the heat exchanger is located) and the compressor chamber (where the compressor is located) into one. This makes the internal chambers of the casing a single, integrated chamber, which also becomes the heat exchange chamber. Consequently, the length of the heat exchange chamber is further increased, the width-to-length ratio is further decreased, and the spatial volume of the heat exchange chamber is increased. With the increased spatial volume of the heat exchange chamber, the airflow carried by the fan and impellers will increase, thereby reducing the noise level of the outdoor unit and improving sound quality.

[0012] Furthermore, by eliminating the air-insulating panel, the installation of the compressor and other components is no longer restricted, thus maximizing the use of the installation space inside the outdoor unit and accelerating heat dissipation on the side where the compressor is located, thereby improving the stability of the outdoor unit's operation.

[0013] Furthermore, 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 greater than 0.2. With this technical solution, the thickness of the main body of the outdoor unit will not be too thin, thus effectively ensuring that the heat exchange cavity has sufficient volume, allowing the fan and fan blades to carry sufficient airflow, thereby ensuring effective heat exchange of the heat exchanger and good sound quality during the operation of the outdoor unit.

[0014] Furthermore, the protrusion length H of the guide ring relative to the outer side of the panel is in the range of 70mm to 80mm. Under this technical solution, the outward protrusion length of the guide ring is appropriate, ensuring sufficient space to accommodate the fan blades and maintain a adequate distance between the tail end and the panel, while also preventing excessive length that would prevent the air guided by the fan blades from being discharged in time, and avoiding an obtrusive appearance of the outdoor unit.

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

[0016] Furthermore, the distance X2 between the tail fin and the panel portion ranges from 44mm to 54mm, and the distance E2 between the tail fin and the air outlet grille portion ranges from 20mm to 30mm. Under this technical solution, firstly, the distance between the tail fin and the panel portion is relatively far, so the gas from the blade tip can be directly guided into the guide ring portion, thereby increasing the air volume of the outdoor unit and improving gas flow efficiency and heat exchange efficiency. Secondly, the distance between the tail fin and the air outlet grille portion is suitable; the distance between them is not too large. Therefore, the gas guided by the fan blade continues to flow forward a short distance within the guide ring portion before being promptly discharged from the air outlet grille portion. The distance within this range is also not too small, which would result in a rapid and chaotic exhaust airflow, thus also ensuring good airflow performance.

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

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

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

[0020] Furthermore, the pressure surface of the fan blades facing the air outlet grille is recessed inwards towards the interior of the housing. This arrangement facilitates the fan blades guiding the airflow forward for discharge.

[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, with the ratio of the length of the portion of the hub within the guide ring portion to the length of the guide ring portion being less than 2 / 3. In this technical solution, the fact that a portion of the hub extends into the guide ring portion indicates that the portion of the fan blades mounted on the hub within the guide ring portion is not too small, thus ensuring the guiding effect on airflow; and the fact that 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 less than 2 / 3 indicates that the length of the portion of the hub within the guide ring portion is not too long, and the space occupied is not too large, thereby controlling the wind resistance within a relatively small range and ensuring the airflow volume.

[0022] Furthermore, the front panel is a sheet metal part, and the panel part, the air guide ring part, and the air outlet grille part are integrally stamped; or, the front panel is a plastic part, and the panel part, the air guide ring part, and the air outlet grille part are integrally formed.

[0023] Under this technical solution, if the front panel is a sheet metal part, the panel part, the air guide ring part, and the air outlet grille part can be manufactured by integral 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 air guide ring part, and the air outlet grille part can be integrally formed by injection molding processes, and the front panel is relatively lightweight.

[0024] Furthermore, the electrical control box of the outdoor unit of the air conditioner is fixedly installed on the side plate of the housing, and is located on the same side of the integrated cavity as the compressor. Attached Figure Description

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0041] This embodiment provides an outdoor unit for an air conditioner, such as... Figures 3 to 8 As shown, the outdoor unit of the air conditioner includes a housing, which includes a front panel 100. The front panel 100 includes a panel portion 110, a guide ring portion 120, and an air outlet grille portion 130, all three being integrated into one unit. The guide ring portion 120 protrudes outward from the panel portion 110, and the air outlet grille portion 130 is located at the air outlet end of the guide ring portion 120. A fan 200 is installed inside the housing, and a hub 300 is coaxially fixed to the output shaft of the fan 200. Fan blades are fixedly mounted on the hub 300. 400; The housing also includes a rear wall panel 180 disposed opposite to the front panel 100, a heat exchange cavity 101 is formed between the front panel 110 and the rear wall panel 180, the heat exchanger 500 of the outdoor unit of the air conditioner is disposed in the 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 or equal to 0.4; along the axial direction, the tip 420 of the fan blade 400 is located in the heat exchange cavity 101, and the tail end 410 is located in the guide ring portion 120.

[0042] The air conditioner outdoor unit provided in this embodiment has a relatively small ratio of width to length of heat exchange cavity 101. Compared with the prior art, with the length of the air conditioner outdoor unit remaining unchanged, the distance between the panel 110 and the rear wall panel 180 of the air conditioner outdoor unit provided in this embodiment is relatively small. The thickness of the main body of the air conditioner outdoor unit provided by the present invention along the front-to-back direction is relatively small. Therefore, the overall size of the air conditioner 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] To accommodate the thinner heat exchange cavity 101, the air conditioner outdoor unit provided by the present invention has a portion of the fan blade 400 disposed within the heat exchange cavity 101, while another portion is disposed within the guide ring portion 120. This arrangement not only fully utilizes the space within the heat exchange cavity 101 and the guide ring portion 120, improving the compactness of the internal structure of the casing, the rationality of space utilization, and the efficiency of space utilization, but also allows the blade tip 420 of the fan blade 400 to continue to accelerate and guide the gas flow within the heat exchange cavity 101, while the tail end 410 of the fan blade 400 can better guide the flow within the guide ring portion 120. Thus, the fan blade 400 can more effectively guide the gas within the heat exchange cavity 101 to the guide ring portion 120, and finally blow it out from the air outlet mesh portion 130, ensuring air volume and heat exchange efficiency. Furthermore, the blade tip 420 of the fan blade 400 is located within the heat exchange cavity 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 farther from the axis of the fan blade 400, thereby allowing the fan blade 400 to be larger, which further accelerates the gas flow within the heat exchange cavity 101. Of course, in other embodiments of this application, the fan blade 400 can also be entirely located within the heat exchange cavity 101, and only coaxially arranged with the guide ring portion 120.

[0044] In addition, the front panel 100's panel portion 110, air guide ring portion 120, and air outlet grille portion 130 are integrated into one unit, which makes the front panel 100 more integrated, resulting in higher structural strength, better appearance consistency, and a more aesthetically pleasing appearance. Moreover, the integrated design of the three units also allows for integrated assembly, which greatly simplifies the assembly process and improves assembly efficiency; it also allows for integrated disassembly.

[0045] Specifically, in this embodiment, as Figure 5 and Figure 7 As shown, the interior of the casing is a single-piece cavity, forming a heat exchange chamber 101. 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 less than 0.3. In the left-to-right direction, the heat exchanger 500 and the fan 200 are located on one side of the single-piece cavity, while the compressor 600 of the outdoor unit is located on the other side. With this configuration, the conventionally installed baffle plate inside the casing is eliminated, merging the heat exchange chamber where the heat exchanger is located and the compressor chamber where the compressor is located into one. Thus, the entire interior of the casing becomes a single, single-piece cavity, which also becomes the heat exchange chamber 101. This further increases the length of the heat exchange chamber 101 and decreases the width-to-length ratio, increasing its volume. As the volume of the heat exchange chamber 101 increases, the airflow carried by the fan 200 and the fan blades 400 increases, thereby reducing the noise and improving the sound quality of the outdoor unit.

[0046] Furthermore, the removal of the air-insulating panel eliminates the restriction on the installation of compressors such as the 600, allowing for maximum utilization of the installation space inside the outdoor unit and accelerating heat dissipation on the side where the compressors such as the 600 are located, thereby improving the stability of the outdoor unit's operation.

[0047] Specifically, in this embodiment, 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 greater than 0.2. With this configuration, the thickness of the main body of the outdoor unit of the air conditioner will not be too thin, thereby effectively ensuring that the heat exchange cavity 101 has sufficient space volume so that the fan 200 and the fan blades 400 can carry sufficient air volume to ensure effective heat exchange of the heat exchanger 500 and good sound quality during the operation of the outdoor unit of the air conditioner.

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

[0049] Specifically, in this embodiment, as Figure 9 As shown, the protrusion length H of the guide ring portion 120 relative to the outer side of the panel portion 110 ranges from 70mm to 80mm. In this configuration, the outward protrusion length of the guide ring portion 120 is appropriate, ensuring sufficient space to accommodate the fan blade 400 and maintain a sufficient distance between its tail end 410 and the panel portion 110, while also avoiding excessive length that would prevent the air guided by the fan blade 400 from being discharged in time, and also preventing the outdoor unit from appearing obtrusive.

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

[0051] In this embodiment, as Figure 9As shown, the distance X2 between the tail fin tip 410 and the panel portion 110 ranges from 44mm to 54mm, and the distance E2 between the tail fin tip 410 and the air outlet grille portion 130 ranges from 20mm to 30mm. With this configuration, firstly, the distance between the tail fin tip 410 of the fan blade 400 and the panel portion 110 is relatively far, allowing the air from the blade tip 420 of the fan blade 400 to be directly guided into the guide ring portion 120, thereby increasing the air volume of the outdoor unit and improving gas flow efficiency and heat exchange efficiency. Secondly, the distance between the tail fin tip 410 of the fan blade 400 and the air outlet grille portion 130 is suitable; the distance between them is not too large. Therefore, the air guided by the fan blade 400 continues to flow forward a short distance within the guide ring portion 120 before being promptly discharged from the air outlet grille portion 130. This distance range is also not too small, which would result in a rapid and chaotic exhaust airflow, thus also ensuring good airflow performance.

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

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

[0054] In this embodiment, the distance from the blade tip 420 to the axis of the fan blade 400 is d1, and the distance from the tail fin end 410 to the axis of the fan blade 400 is d2, where 0mm < d1 - d2 ≤ 2mm. With this configuration, the radius of the fan blade 400 at the blade tip 420 is larger than the radius at the tail fin end 410, thus 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 of the guide ring portion 120 is 8mm, and d1-d2=0.9mm. The value of D is relatively moderate, which can better balance the effects of avoiding backflow and avoiding collision.

[0056] Specifically, in this embodiment, the pressure surface 401 of the fan blade 400 facing the air outlet grille 130 is recessed into the housing. This arrangement helps the fan blade 400 guide the airflow forward for discharge.

[0057] Specifically, in this embodiment, as 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. 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, the fact that a portion of the hub 300 extends into the guide ring portion 120 indicates that the portion of the fan blade 400 mounted on the hub 300 within the guide ring portion 120 is not too small, thus ensuring proper airflow guidance. 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 excessive, resulting in minimal space occupation. This allows for control of wind resistance within a relatively small range, thereby ensuring sufficient airflow.

[0058] Specifically, in this embodiment, the front panel 100 is a sheet metal part. The panel portion 110, the air guide ring portion 120, and the air outlet grille portion 130 are manufactured by integral stamping and bending processes, resulting in high structural strength for the sheet metal part. Optionally, in other embodiments of this application, the front panel 100 can also be a plastic part. The panel portion 110, the air guide ring portion 120, and the air outlet grille portion 130 can be integrally formed by injection molding or other processes. In this case, the front panel 100 is relatively lightweight.

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