Detailed Implementation

They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0023] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "support" should be interpreted broadly. For example, they can refer to fixed supports, detachable supports, or integral supports; they can refer to mechanical supports or electrical supports; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] This application provides an outdoor enclosure 11 for use in an outdoor unit 10.

[0025] This application provides an outdoor unit 10, please refer to... Figure 1 , Figures 5 to 9 The outdoor unit 10 includes an outdoor heat exchanger 12, an outdoor fan 14, a water pump 13, a motor assembly 15, and an outdoor enclosure 11 in any embodiment of this application.

[0026] This application provides an air conditioner 100. Please refer to [link / reference]. Figures 10 to 11 The air conditioner 100 includes an indoor unit and an outdoor unit 10 in any embodiment of this application. The indoor unit includes an indoor heat exchanger, and the indoor heat exchanger is in heat exchange communication with the outdoor heat exchanger 12.

[0027] It is understood that the type of air conditioner 100 in this application is not limited; for example, it can be a window air conditioner. A window air conditioner is an integrated air conditioner, that is, the outdoor unit 10 and the indoor unit are integrated into one box, thus making the structure compact and reducing the space occupied indoors.

[0028] For example, an installation opening is formed in the wall, a window can be disposed in the installation opening, and the air conditioner 100 can be installed in the installation opening. The two sides of the window are the indoor side and the outdoor side, respectively. The indoor unit is located on the indoor side of the window, and the outdoor unit 10 is located on the outdoor side of the window. Of course, the air conditioner 100 can also be installed in other locations that are roughly similar to the window.

[0029] For example, the air conditioner 100 can be a PTAC (Packaged Terminal Air Conditioner) window unit, that is, the air conditioner 100 has a fresh air function while cooling and heating, thus improving air quality.

[0030] In some embodiments, the air conditioner 100 includes a chassis 20, a housing, and a partition 30. The housing is disposed above the chassis 20, and the outdoor unit 10 and the indoor unit are disposed within the space defined by the chassis 20 and the housing. The partition 30 separates the indoor unit and the outdoor unit 10.

[0031] The chassis 20 is positioned at the bottom of the outdoor unit 10 and the indoor unit to support them. The outer casing is placed on the chassis 20. Thus, the indoor and outdoor units 10 are located within the space defined by the chassis 20 and the outer casing, providing protection for them and ensuring the overall structural stability of the air conditioner 100, facilitating its installation. The partition 30 separates the indoor and outdoor units 10; the indoor unit is located on the side of the partition 30 facing inwards, and the outdoor unit 10 is located on the side of the partition 30 facing outwards.

[0032] Understandably, without a partition, the cold air drawn in by the indoor fan may leak directly from the casing to the outdoor side, or the hot air drawn in by the outdoor fan may directly enter the indoor side, causing a decrease in the cooling and heating efficiency of the air conditioner and affecting its performance.

[0033] Therefore, the partition 30 is used to isolate indoor air from outdoor air, physically blocking the direct connection between the indoor and outdoor air ducts. This ensures that indoor air can only be drawn in by the indoor fan, heat-exchanged by the indoor heat exchanger, and then blown back indoors; outdoor air can only be drawn in by the outdoor fan 14, heat-exchanged by the outdoor heat exchanger 12, and then discharged outdoors. This allows the air conditioner 100 to efficiently complete the heat exchange process of indoor heat absorption and outdoor heat release (cooling) or "outdoor heat absorption and indoor heat release" (heating). Of course, the partition 30 also provides structural support and dust and water protection, reducing the likelihood of rainwater and dust directly entering the indoor side.

[0034] The partition 30 can be a sheet metal part, which is lightweight and high-strength, making it easy to mass-produce and thus ensuring the structural strength of the partition 30.

[0035] The outdoor heat exchanger 12 is used for heat exchange with outdoor air, and the indoor heat exchanger is used for heat exchange with indoor air. Both the indoor and outdoor heat exchangers 12 function as evaporators or condensers. The working principle of the air conditioner 100 is briefly described below.

[0036] In cooling mode, the outdoor heat exchanger 12 acts as a condenser, and the indoor heat exchanger acts as an evaporator. The compressor draws in low-temperature, low-pressure gaseous refrigerant and compresses it into high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant enters the outdoor heat exchanger 12, and the outdoor fan 14 draws in outdoor air. The high-temperature, high-pressure refrigerant exchanges heat with the outdoor air, lowering its temperature and causing it to condense from a gaseous state into a liquid state. At the same time, it releases a large amount of heat to the outdoor air. The high-pressure liquid refrigerant passes through a throttling device and becomes low-temperature, low-pressure liquid refrigerant, which then enters the indoor heat exchanger. The indoor fan draws in indoor air, and the low-temperature, low-pressure liquid refrigerant exchanges heat with the indoor air, absorbing heat from the indoor air and evaporating from a liquid state into a gaseous state. Simultaneously, it lowers the indoor air temperature, and the cooled air is blown back into the room, achieving cooling.

[0037] In heating mode, the outdoor heat exchanger 12 is used as an evaporator, and the indoor heat exchanger is used as a condenser. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas first enters the room and exchanges heat with the indoor heat exchanger. The indoor fan blows through the indoor heat exchanger, and the refrigerant releases heat to the indoor air and condenses into a liquid, thus raising the temperature of the indoor air. The high-pressure liquid refrigerant passes through a throttling device and becomes a low-temperature liquid. The low-temperature, low-pressure liquid refrigerant enters the outdoor heat exchanger 12, where it absorbs heat from the outdoor air and evaporates into a gas. In this way, heating is achieved.

[0038] Please see Figures 1 to 4 The outdoor enclosure 11 includes a panel 110 and a guide ring 111.

[0039] The panel 110 is provided with a mounting position for installing the outdoor heat exchanger 12. The panel 110 has an air inlet surface 110a and an air outlet surface 110b.

[0040] The water pumping component 13 is connected to the periphery of the outdoor fan 14 and is used to pump liquid toward the outdoor heat exchanger 12.

[0041] The outdoor heat exchanger 12 is installed at the mounting position and is positioned opposite to the air outlet surface 110b.

[0042] Please see Figure 7 and Figure 9 The motor assembly 15 includes a motor frame 152 and a motor 151. The motor 151 is fixed to the motor frame 152 and connected to the outdoor fan 14. The motor frame 152 is rotatably connected to the outdoor enclosure 11.

[0043] Panel 110 serves as the main structure of the outdoor enclosure 11, providing support, protection, and integrated installation for the outdoor heat exchanger 12, water pump 13, outdoor fan 14, etc.

[0044] It is understood that the air inlet surface 110a is the side surface of the panel 110 located on the air inlet side of the guide ring 111 when the outdoor fan 14 is in operation, and the air outlet surface 110b is the side surface of the panel 110 located on the air outlet side of the guide ring 111. The air inlet surface 110a and the air outlet surface 110b are located on opposite sides of the guide ring 111 along the axial direction.

[0045] In this application, the air inlet surface 110a can be the front surface of the panel 110, and the air outlet surface 110b can be the rear surface of the panel 110. When the outdoor fan 14 is in operation, the airflow passes through the guide ring 111 and leaves the outdoor enclosure 11 along the direction from the air inlet surface 110a to the air outlet surface 110b, and flows to the outdoor heat exchanger 12 to achieve heat exchange.

[0046] Here, the rear side is the direction facing the outside when the air conditioner 100 is in normal use, and the front side is the direction facing the inside when the air conditioner 100 is in normal use.

[0047] The guide ring 111 forms an airflow channel 111a. The airflow channel 111a can guide the airflow, so that when the outdoor fan 14 is rotating, the airflow maintains the concentration of wind force in the flow, and blows from front to back through the guide ring 111 to the outdoor heat exchanger 12.

[0048] It is understandable that when the air conditioner 100 is working, the condensate produced by the indoor heat exchanger will flow towards the outdoor side and accumulate. When the outdoor fan 14 rotates, the water pump 13 rotates and drives the condensate upward. The condensate that is lifted drops onto the outdoor heat exchanger 12 to carry away the heat of the outdoor heat exchanger 12, thereby increasing the heat exchange efficiency of the outdoor heat exchanger 12.

[0049] It should be noted that the outdoor unit 10 includes an outdoor water collection pan located below the outdoor heat exchanger 12 to collect the condensate produced by the outdoor heat exchanger 12. The indoor unit includes an indoor water collection pan located below the indoor heat exchanger to collect the condensate produced by the indoor heat exchanger. The indoor and outdoor water collection pans can be an integrated structure or separate structures. The indoor and outdoor water collection pans can be different structures from the chassis 20 or part of the chassis 20; no restrictions are placed here. The condensate produced by the indoor heat exchanger can be guided from the indoor water collection pan to the outdoor water collection pan via a drainage structure. When the outdoor fan 14 rotates, part of the water pump 13 extends into the outdoor water collection pan to drive the condensate upward.

[0050] The outdoor heat exchanger 12 is positioned opposite the air outlet surface 110b, meaning it is located on the rear side of the panel 110. The motor assembly 15 can be positioned opposite the air inlet surface 110a, meaning it is located on the front side of the panel 110. Thus, the outdoor enclosure 11 provides support for the outdoor heat exchanger 12, motor assembly 15, outdoor fan 14, and water jetting component 13. Simultaneously, the positions of the outdoor heat exchanger 12 and motor 151 relative to the outdoor enclosure 11 are fixed, ensuring the heat exchange performance of the outdoor heat exchanger 12.

[0051] For example, the top portion of the panel 110 extends above the outdoor heat exchanger 12, so that water agitated by the water pump 13 can be thrown towards the top of the panel 110, and then the water flow falls onto the refrigerant pipe of the outdoor heat exchanger 12 below under the action of wind pressure and gravity, resulting in higher heat exchange efficiency.

[0052] The motor frame 152 is rotatably connected to the outdoor enclosure 11. Thus, after one end of the motor frame 152 is positioned and connected to the outdoor enclosure 11, the installation of the motor frame 152 can be automatically corrected by rotating the other end of the motor frame 152 relative to the outdoor enclosure 11, eliminating the need for multiple alignment adjustments and improving assembly efficiency.

[0053] The form of the outdoor fan 14 is not limited; it can be an axial flow fan, a centrifugal fan, etc.

[0054] The water-applying component 13 is located on the outer periphery of the outdoor fan 14. The water-applying component 13 can be integrally formed with the outdoor fan 14, or it can be separately formed from the outdoor fan 14 and then connected. During installation, the water-applying component 13 can be first assembled with the outdoor fan 14 to form a whole before being assembled with the motor 151.

[0055] For example, the water-discharging component 13 is annular. The water-discharging component 13 can be connected to the blades of the outdoor fan 14 without the need for additional drive components. For example, the water-discharging component 13 is located on the side of the guide ring 111 away from the indoor unit to increase the distance between the water-discharging component 13 and the indoor unit, thereby reducing the probability of condensate water agitated by the water-discharging component 13 entering the indoor unit.

[0056] Please see Figures 1 to 4 The air guide ring 111 protrudes from the air inlet surface 110a. The air guide ring 111 includes an outer ring structure 1111 and an inner ring structure 1112 that are connected to each other. The outer ring structure 1111 is connected to the panel 110. The inner ring structure 1112 encloses a first space 1112a. The first space 1112a is used to accommodate at least a portion of the water spraying component 13 and the outdoor fan 14. The first space 1112a defines at least a portion of the airflow channel 111a. The outer ring structure 1111 surrounds the outer periphery of the inner ring structure 1112, and an annular groove 111b is formed between the two. The end of the annular groove 111b near the air inlet surface 110a is closed.

[0057] The air guide ring 111 protrudes from the air inlet surface 110a, meaning that part of the air guide ring 111 is located on the front side of the panel 110. This facilitates guiding the airflow drawn in by the outdoor fan 14 into the airflow channel 111a, and concentrating the airflow towards the outdoor heat exchanger 12.

[0058] It is understood that the inner ring structure 1112 is closer to the center of the guide ring 111 than the outer ring structure 1111, and the diameter of the inner ring structure 1112 is smaller than the diameter of the outer ring structure 1111. For example, the outer ring structure 1111 and the inner ring structure 1112 are coaxially arranged.

[0059] The outer ring structure 1111 is connected to the panel 110. The outer ring structure 1111 is closer to the panel 110 than the inner ring structure 1112. The flow guide ring 111 is connected to the panel 110 through the outer ring structure 1111. The flow guide ring 111 can be formed in the central area of ​​the panel 110. The connection method between the outer ring structure 1111 and the panel 110 is not limited. It can be integrally formed on the panel 110 or separately formed, and then the flow guide ring 111 is installed on the panel 110. There is no limitation here.

[0060] The inner ring structure 1112 encloses the first space 1112a, meaning that at least a portion of the water pump 13 and the outdoor fan 14 are located in the hollow space defined by the inner wall of the inner ring structure 1112. Thus, when the outdoor fan 14 rotates, outdoor airflow is drawn into the first space 1112a.

[0061] The first space 1112a defines at least a portion of the airflow channel 111a. Alternatively, the first space 1112a may define the entire airflow channel 111a, and the airflow may only contact the inner ring structure 1112 during the flow through the guide ring 111. Or, the first space 1112a may define only a portion of the airflow channel 111a, and the other portion may be defined by the outer ring structure 1111. In this way, the air volume can be increased and the heat exchange efficiency of the outdoor heat exchanger 12 can be improved.

[0062] The outer ring structure 1111 surrounds the outer periphery of the inner ring structure 1112, forming a double-layer structure. An annular groove 111b is formed between the outer ring structure 1111 and the inner ring structure 1112. The end of the annular groove 111b near the air inlet surface 110a is closed, meaning that the ends of the outer ring structure 1111 and the inner ring structure 1112 near the air inlet surface 110a are connected to each other. The ends of the outer ring structure 1111 and the inner ring structure 1112 near the air outlet surface 110b are spaced apart, thus forming an annular groove 111b that opens towards the air outlet surface 110b. The annular groove 111b is a blind groove. Therefore, the end of the guide ring 111 near the air inlet surface 110a is complete without any gaps 114a. The end of the guide ring 111 near the air inlet surface 110a is thicker, providing sufficient strength and reducing the likelihood of deformation under stress. On the side of the air guide ring 111 near the air outlet surface 110b, the double-layer setting of the outer ring structure 1111 and the inner ring structure 1112 results in higher strength of the air guide ring 111, the inner ring structure 1112 can get support from the outer ring structure 1111, and the outer ring structure 1111 can get support from the panel 110, resulting in higher overall stability.

[0063] Understandably, in related technologies, the air guide ring protrudes from the outdoor enclosure and is turned outward to increase airflow. However, this part is formed as a cantilever structure and is relatively thin. During the use of the air conditioner, the air guide ring is prone to deformation due to temperature changes (such as thermal expansion and contraction, ambient temperature below -20℃) and external forces (such as vibration and installation), which affects the reliability of the air conditioner.

[0064] The outdoor enclosure 11 provided in this embodiment has a double-layer structure for the air guide ring 111. The inner ring structure 1112 is adapted to the outdoor fan 14 and the water spraying component 13, and the outer ring structure 1111 surrounds the outer periphery of the inner ring structure 1112. The two are connected to each other at the end near the air inlet surface 110a, which will not affect the air intake of the outdoor fan 14. At the same time, the air guide ring 111 has sufficient thickness at the end near the air inlet surface 110a, resulting in high structural strength and effectively guiding airflow into the air guide ring 111. The outer ring structure 1111 provides structural support for the inner ring structure 1112, increases the overall structural strength of the outdoor enclosure 11 at the air guide ring 111, and reduces the probability of deformation of the outdoor enclosure 11 due to temperature changes or external forces. Of course, the outer ring structure 1111 also helps to increase the air output of the air guide ring 111.

[0065] It should be noted that the guide ring 111 has a double-layer structure design, which also allows the guide ring 111 to be adapted to more materials. For example, in order to adapt to the use scenarios in low temperature environments such as -20℃ and -30℃, the guide ring 111 needs to be made of a low temperature resistant material such as polypropylene to reduce the probability of deformation due to the material itself in low temperature environments. However, the strength of polypropylene is not as good as ABS plastic (a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S) monomers) or high-impact polystyrene. However, the double-layer structure makes it easy for the guide ring 111 to be made of a low temperature resistant material, which is both resistant to low temperature deformation and has sufficient structural strength.

[0066] For example, in some embodiments, the outdoor enclosure 11 is a modified polypropylene structure.

[0067] Modified polypropylene structures refer to structures based on polypropylene that incorporate other components through physical or chemical methods to improve its properties. This allows the outdoor enclosure panel 11 to meet low-temperature operating conditions such as -20℃ and -30℃, possessing sufficient structural strength and a low probability of deformation.

[0068] For example, the outdoor enclosure 11 can be a multiphase composite structure of polypropylene and fiber, and the fiber can be glass fiber, which is not limited here.

[0069] In some embodiments, please refer to Figure 2 and Figure 8 The outer ring structure 1111 has a first shaft end face 1111a, and the inner ring structure 1112 has a second shaft end face 1112b. The first shaft end face 1111a is connected to the air outlet surface 110b, and the second shaft end face 1112b is spaced apart from the first shaft end face 1111a and the air outlet surface 110b.

[0070] The first axial end face 1111a is the side end face of the outer ring structure 1111 that is axially away from the air inlet surface 110a, and the second axial end face 1112b is the side end face of the inner ring structure 1112 that is away from the air inlet surface 110a. The first axial end face 1111a is connected to the air outlet surface 110b. Exemplarily, the first axial end face 1111a and the air outlet surface 110b have a smooth transition.

[0071] The second shaft end face 1112b and the first shaft end face 1111a are spaced apart, and the gap between them defines the opening of the annular groove 111b.

[0072] Along the direction from the air inlet surface 110a to the air outlet surface 110b, the first shaft end face 1111a and the second shaft end face 1112b are flush, and the first space 1112a defines the airflow channel 111a.

[0073] In this embodiment, the first shaft end face 1111a does not protrude toward the air outlet surface 110b relative to the second shaft end face 1112b. The first shaft end face 1111a and the second shaft end face 1112b have no difference in axial direction. The second shaft end face 1112b can define the outlet of the airflow channel 111a. The first space 1112a defines the complete airflow channel 111a. The airflow drawn in by the outdoor fan 14 can leave the outdoor enclosure 11 and blow toward the outdoor heat exchanger 12 after passing through the first space 1112a defined by the inner ring structure 1112. This helps to improve the wind field guidance stability of the guide ring 111.

[0074] In other embodiments, please refer to Figure 2 and Figure 8 Along the direction from the air inlet surface 110a to the air outlet surface 110b, the position of the first shaft end face 1111a is higher than that of the second shaft end face 1112b, and the first space 1112a and the annular groove 111b define the airflow channel 111a.

[0075] In this embodiment, the first shaft end face 1111a protrudes towards the air outlet surface 110b relative to the second shaft end face 1112b. The first shaft end face 1111a and the second shaft end face 1112b have an axial height difference. The first shaft end face 1111a defines the outlet of the airflow channel 111a. The first space 1112a and the annular groove 111b together define the airflow channel 111a. Thus, the airflow drawn in by the outdoor fan 14 will enter the part of the outer ring structure 1111 that exceeds the inner ring structure 1112 after passing through the first space 1112a defined by the inner ring structure 1112. This facilitates the expansion of the airflow volume, improves the airflow efficiency, and thereby improves the heat exchange performance of the outdoor heat exchanger 12.

[0076] For example, the axial spacing between the first shaft end face 1111a and the second shaft end face 1112b does not exceed 1 / 3 of the axial dimension of the guide ring 111. This facilitates improving air outlet efficiency while ensuring the overall structural strength of the guide ring 111.

[0077] In some embodiments, please refer to Figure 2 and Figure 8 Along the direction from the air inlet surface 110a to the air outlet surface 110b, the positions of the first shaft end face 1111a and the second shaft end face 1112b do not extend beyond the air outlet surface 110b.

[0078] In this embodiment, neither the first shaft end face 1111a nor the second shaft end face 1112b protrudes relative to the air outlet surface 110b. That is, the outer ring structure 1111 extends from the connection point with the air outlet surface 110b towards the air inlet surface 110a. The connection point between the outer ring structure 1111 and the air outlet surface 110b is the highest position of the guide ring 111 in the direction from the air inlet surface 110a to the air outlet surface 110b. In this way, the cantilever size of the guide ring 111 is small and the overall structural strength is high, which helps to reduce the probability of deformation of the guide ring 111. Of course, it also facilitates demolding.

[0079] In some embodiments, please refer to Figure 1 and Figure 8 Along the radial direction away from the center of the guide ring 111, the air outlet surface 110b bends and extends away from the connection point with the outer ring structure 1111 in a direction away from the air inlet surface 110a. That is to say, the air outlet surface 110b has an overall structure that is concave towards the center of the guide ring 111 and on the side of the air inlet surface 110a.

[0080] Thus, when the airflow leaves the guide ring 111, the air outlet surface 110b can also play a certain role in guiding the airflow, directing the airflow to the outdoor heat exchanger 12 and reducing airflow loss.

[0081] In some embodiments, please refer to Figure 1 and Figure 2 The outdoor enclosure 11 includes multiple connecting structures 114, which are spaced apart circumferentially within the annular groove 111b. One end of each connecting structure 114 is connected to the outer ring structure 1111, and the other end is connected to the inner ring structure 1112.

[0082] The number of connection structures 114 can be two, three or more, and there is no limit here.

[0083] Multiple connecting structures 114 are arranged circumferentially within the annular groove 111b. The multiple connecting structures 114 can be arranged at equal intervals or at unequal intervals, and there is no limitation on this.

[0084] In this embodiment, the connecting structure 114 is disposed in the annular groove 111b and connects the outer ring structure 1111 and the inner ring structure 1112. In this way, the probability of deformation of the inner ring structure 1112 can be further reduced. The outer ring structure 1111 and the inner ring structure 1112 are further integrated together by the connecting structure 114. Both ends of the inner ring structure 1112 along the axial direction can be supported. The inner ring structure 1112 has almost no cantilever size, and the overall structural strength of the outdoor enclosure 11 is higher.

[0085] In some embodiments, please refer to Figure 2 The outdoor enclosure 11 includes a connecting ring 115, which connects the outer ring structure 1111 and the inner ring structure 1112 at one end near the air inlet surface 110a, and together with the outer ring structure 1111 and the inner ring structure 1112, defines an annular groove 111b.

[0086] In other words, the outer ring structure 1111 and the inner ring structure 1112 are connected at the end near the air inlet surface 110a by a connecting ring 115. Thus, the connecting ring 115 is the end of the closed ring groove 111b near the air inlet surface 110a. As a result, the guide ring 111 is thicker and stronger at the end near the air inlet surface 110a, and at the same time, it can better guide the airflow without causing air volume loss.

[0087] The connecting structure 114 is connected to the connecting ring 115, and extends from the connection point with the connecting ring 115 to be connected to the first shaft end face 1111a and the second shaft end face 1112b respectively.

[0088] In this embodiment, there is no gap between the connecting structure 114 and the connecting ring 115. On the one hand, the connecting structure 114 and the connecting ring 115 can be integrated together, which facilitates the overall integration of the outer ring structure 1111, the inner ring structure 1112, the connecting structure 114, and the connecting ring 115, thereby increasing the structural strength. On the other hand, it can also reduce the probability of airflow loss or turbulence due to airflow entering between the connecting ring 115 and the connecting structure 114. The connecting structure 114 extends to connect with the first shaft end face 1111a and the second shaft end face 1112b, which facilitates the formation of support for the first shaft end face 1111a and the second shaft end face 1112b, reducing the probability of the guide ring 111 deforming from the first shaft end face 1111a and the second shaft end face 1112b, and increasing the overall structural strength of the outdoor enclosure 11.

[0089] In some embodiments, please refer to Figure 2 The connecting structure 114 has a notch 114a, which penetrates the connecting structure 114 along the circumference of the guide ring 111, and the notches 114a of each connecting structure 114 are interconnected.

[0090] In this embodiment, the notch 114a is provided so that the connecting structure 114 does not divide the annular groove 111b into multiple unconnected subspaces. That is, the connecting structure 114 is provided in the annular groove 111b but does not affect the overall continuity of the annular groove 111b. This facilitates airflow, reduces airflow loss and the probability of turbulence, and ensures air outlet efficiency.

[0091] The specific construction of the connection structure 114 is not limited.

[0092] In some embodiments, please refer to Figure 2 The connecting structure 114 includes a first stiffener 1141, a second stiffener 1142, and a third stiffener 1143. The first stiffener 1141 is connected to the inner wall of the outer ring structure 1111, and the third stiffener 1143 is connected to the outer wall of the inner ring structure 1112. The second stiffener 1142 is connected to the connecting ring 115 and connects the first stiffener 1141 and the third stiffener 1143. The first stiffener 1141 and the third stiffener 1143 are spaced apart at one end near the air outlet surface 110b to define a notch 114a.

[0093] For example, along the direction from the air inlet surface 110a to the air outlet surface 110b, the end of the third stiffener 1143 near the air outlet surface 110b is lower than the end of the first stiffener 1141 near the air outlet surface 110b.

[0094] In this embodiment, the first stiffener 1141, the second stiffener 1142, and the third stiffener 1143 are generally formed in a U-shape. The first stiffener 1141 provides support for the outer ring structure 1111, the third stiffener 1143 provides support for the inner ring structure 1112, and the second stiffener 1142 connects the first stiffener 1141 and the third stiffener 1143 and is connected to the connecting ring 115 to integrate the various parts together. The overall structural strength of the outdoor enclosure 11 is high, and the structure of the connecting structure 114 is simple and easy to manufacture.

[0095] For example, the connecting structure 114 is integrally formed on the guide ring 111.

[0096] In some embodiments, please refer to Figure 1 and Figure 3 The outdoor enclosure 11 includes a plurality of first reinforcing ribs 116, which are recessed in the air inlet surface 110a and protrude from the air outlet surface 110b.

[0097] In this embodiment, the first reinforcing rib 116 is provided to increase the structural strength of the panel 110, improve the deformation resistance of the panel 110, and increase the overall structural strength of the outdoor enclosure 11.

[0098] In some embodiments, the first reinforcing rib 116 has a columnar structure, and any two adjacent first reinforcing ribs 116 are connected to each other.

[0099] Understandably, the panel needs to be used in conjunction with the outdoor heat exchanger and motor. The panel is a single-panel structure with a small thickness, which poses a risk of bending and deformation.

[0100] In this embodiment, the first reinforcing rib 116 has a columnar structure, which can significantly improve the local stiffness of the panel 110 and reduce the probability of deformation of the panel 110. At the same time, it is easy to form, and any two adjacent first reinforcing ribs 116 can be connected to each other, and each first reinforcing rib 116 can form a support network, further improving the overall strength of the panel 110.

[0101] In some embodiments, please refer to Figure 1 The plurality of first reinforcing ribs 116 include a first part and a second part, the first part and the second part are disposed on opposite sides of the guide ring 111 along a first direction, the first part and / or the second part are arranged in a matrix, wherein the first direction is perpendicular to the height direction of the outdoor enclosure 11.

[0102] For example, the first direction is the left and right direction.

[0103] In this embodiment, the guide ring 111 is provided with a plurality of first reinforcing ribs 116 on both sides of the first direction. The first reinforcing ribs 116 and / or the second reinforcing ribs are arranged in a matrix, that is, the plurality of first reinforcing ribs 116 in the first part and / or the second part are distributed in regular rows and columns to form a support grid. In this way, it can effectively resist bending, torsion and compressive loads from all directions. The matrix arrangement can distribute stress more evenly and reduce the probability of local deformation of the panel 110.

[0104] Of course, the two ends of the panel 110 along the height direction can also have reinforcing structures, which is not limited here.

[0105] In some embodiments, please refer to Figure 1 and Figure 3 The outdoor enclosure 11 includes a wiring structure 117, which is connected to the panel 110 and protrudes from the air inlet surface 110a. The wiring structure 117 has at least one wiring groove 117a through which the wire harness passes.

[0106] In this embodiment, a wiring structure 117 is formed on the front side of the panel 110. The wiring trough 117a allows the wiring harness of the power supply 151, communication harness, or other wiring harnesses to pass through. The wiring trough 117a can integrate the wiring harnesses together and constrain them, making the wiring path more fixed, reducing the probability of the wiring harnesses being messy or shifting due to vibration, and increasing the reliability of the wiring. At the same time, in this embodiment, the wiring structure 117 is formed using the outdoor enclosure 11. The wiring harness can be connected to the motor 151 through the wiring trough 117a or connected to the indoor unit through the partition 30, eliminating the need to set up the wiring structure 117 in other structures.

[0107] In some embodiments, please refer to Figure 7 and Figure 9 The outdoor enclosure 11 includes a motor mounting part 118, which is connected to the panel 110 and protrudes from the air inlet surface 110a. The motor mounting part 118 has a snap-fit ​​structure for rotating with the motor frame 152.

[0108] It is understood that the snap-fit ​​structure can be a hook or a slot, and there are no restrictions on this.

[0109] Specifically, after one end of the motor frame 152 is positioned in conjunction with the snap-fit ​​structure along the height direction, the other end of the motor frame 152 along the height direction can rotate around the connection between the motor frame 152 and the snap-fit ​​structure until it mates with the panel 110. Then, the other end of the motor frame 152 is connected to the panel 110 by screws or other fasteners. In this way, during the installation of the motor frame 152, there is no need for multi-point positioning, reducing the time for manual alignment correction and increasing installation efficiency.

[0110] In some embodiments, the outdoor enclosure 11 is an integral structure.

[0111] For example, the outdoor enclosure 11 is a one-piece injection-molded structure.

[0112] In this embodiment, the outdoor enclosure 11 is integrally formed, which has a simple structure, fast production speed, and reduces assembly processes. At the same time, there are no splicing installation marks on the outdoor enclosure 11, which makes it easier to ensure the overall strength.

[0113] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6 The outdoor enclosure 11 includes a first water guide 112 and a second water guide 113 connected to each other. The first water guide 112 and the second water guide 113 protrude from the side of the guide ring 111 near the air inlet surface 110a. The first water guide 112 has a first flow channel 112a, at least a portion of which is located on the rotation path of the outdoor fan 14. The second water guide 113 has a second flow channel 113a, one end of which is connected to the first flow channel 112a along the axial direction, and the other end is connected to the first space 1112a, so as to guide the liquid agitated by the outdoor fan 14 through the first flow channel 112a to the water agitator 13.

[0114] In other words, the first water guide 112 protrudes from the front side of the guide ring 111, that is, the end closer to the indoor side.

[0115] The first flow channel 112a is a channel for liquid flow defined by the shape of the first water guide 112. At least a portion of the first flow channel 112a is located on the rotation path of the outdoor fan 14, that is, at least a portion of the first flow channel 112a is on the rotation trajectory of the outdoor fan 14. During the rotation of the outdoor fan 14, the outdoor fan 14 will come into contact with the first water guide 112, so that the water agitated by the outdoor fan 14 can be contained within the first flow channel 112a without splashing outwards.

[0116] The second water guide 113 protrudes from the front side of the guide ring 111. The second water guide 113 is connected and fitted with the first water guide 112 along the circumferential direction of the guide ring 111, and the second water guide 113 is located downstream of the first water guide 112 along the fluid flow direction.

[0117] The second flow channel 113a is a channel for liquid flow defined by the shape of the second water guide 113. One end of the second flow channel 113a is connected to the first flow channel 112a along the axial direction, and the other end is connected to the second flow channel 113a along the axial direction. That is, the water agitated by the outdoor fan 14 flows along the rotation path in the first flow channel 112a and can flow to the second flow channel 113a under the action of the wind. Under the action of the second flow channel 113a, it flows back to the airflow channel 111a along the axial direction. For example, it flows to the inner wall surface of the guide ring 111 and is received by the water agitator 13. The water agitator 13 then pushes the condensate to the outdoor heat exchanger 12 to achieve heat exchange.

[0118] It is understandable that the water-discharging component is a closed ring, and the condensate water it discharging has a small diffusion range and is not easy to splash. However, the outdoor fan discharging condensate water relies on the fan blades. In related technologies, some of the condensate water discharging by the water-discharging component is received by the outdoor fan, or when the condensate water accumulation is high, the outdoor fan directly discharging the condensate water. The condensate water will splash under the action of the outdoor fan, which is not conducive to the heat exchange efficiency of the outdoor heat exchanger and is prone to creating safety hazards.

[0119] The outdoor enclosure 11 provided in this embodiment has a first flow channel 112a adapted to the rotation path of the outdoor fan 14, which guides the condensate water stirred up by the outdoor fan 14, reducing the probability of the water stirred up by the outdoor fan 14 splashing outwards. At the same time, under the action of the wind force of the outdoor fan 14, the condensate water stirred up by the outdoor fan 14 flows through the first flow channel 112a to the second flow channel 113a, and flows back to the water spraying component 13 axially from the second flow channel 113a. In this way, the water stirred up by the outdoor fan 14 will not splash outwards, and can return to the guide ring 111 to be used by the water spraying component 13 and sprayed towards the outdoor heat exchanger 12, reducing the probability of condensate water waste and increasing the heat exchange performance of the outdoor heat exchanger 12. Of course, the size of the first water guide 112 and the second water guide 113 can also be small. The first water guide 112 and the second water guide 113 can be set only in the bottom area of ​​the guide ring 111. When the outdoor fan 14 starts to generate condensate, it receives the condensate and guides it to the guide ring 111, reducing the impact on the efficiency of the air duct.

[0120] The size of the first water guide 112 only needs to be adapted to the blade of one of the outdoor fans 14, without forming an integral structure that wraps around the blade, thus reducing the impact on the duct efficiency of the guide ring 111.

[0121] In some embodiments, please refer to Figure 3 and Figure 6 The first flow channel 112a extends circumferentially along the guide ring 111.

[0122] In other words, the first flow channel 112a can be formed as an annular groove extending circumferentially along the guide ring 111. The entire first flow channel 112a is located on the rotation path of the outdoor fan 14. When the outdoor fan 14 rotates, each fan blade will pass through the first flow channel 112a to cut into the first flow channel 112a, and the condensate water that is stirred up will flow along the first flow channel 112a to the second flow channel 113a.

[0123] In this embodiment, the first flow channel 112a extends circumferentially along the guide ring 111, so that the condensate water generated by the outdoor fan 14 falls into the first flow channel 112a, and at the same time, flows stably along the first flow channel 112a to the second flow channel 113a.

[0124] In some embodiments, please refer to Figure 3 and Figure 6 The second flow channel 113a extends along the axial direction of the guide ring 111.

[0125] In this embodiment, the second flow channel 113a is formed as a channel extending axially along the guide ring 111. Thus, one end of the second flow channel 113a along the axial direction receives condensate from the first flow channel 112a. Then, under the action of the wind force of the outdoor fan 14, the condensate flows axially towards the air inlet side of the guide ring 111, is received by the water spraying component 13, and sprays towards the outdoor heat exchanger 12. The structure is simple.

[0126] In some embodiments, please refer to Figure 3 and Figure 6 Along the radial direction close to the center of the guide ring 111, no part of the second water guide 113 extends beyond the inner wall surface of the guide ring 111, that is, it does not extend beyond the inner wall surface of the inner ring structure 1112.

[0127] It is understandable that the center of the guide ring 111 is the geometric center of the airflow channel 111a.

[0128] In this embodiment, in the radial direction close to the center of the guide ring 111, the highest surface of the second water guide 113 will not exceed the plane where the guide ring 111 is located. No part of the second water guide 113 will block the guide ring 111. Thus, the second water guide 113 can guide the condensate back to the water pump 13 without blocking the airflow channel 111a. That is, it does not affect the gap between the guide ring 111 and the blades of the outdoor fan 14. The second water guide 113 does not affect the air intake of the outdoor fan 14, reducing the impact on the efficiency of the air duct.

[0129] In some embodiments, please refer to Figure 3 and Figure 6 The second water guide 113 has a first end face 113b and a second end face 113c along the circumferential direction. A second flow channel 113a is defined between the first end face 113b and the second end face 113c. The first end face 113b is connected to the first water guide 112.

[0130] The first end face 113b is the side end face of the second water guide 113 that is close to the first water guide 112 along the circumferential direction, and the second end face 113c is the side end face of the second water guide 113 that is far away from the first water guide 112 along the circumferential direction. The first end face 113b and the second end face 113c are spaced apart along the circumferential direction, and the space between them defines the second flow channel 113a.

[0131] Please see Figure 3 and Figure 6 Along the radial direction close to the center of the guide ring 111, the first end face 113b and the second end face 113c are the highest surfaces of the second water guide 113.

[0132] In other words, in the radial direction toward the center of the guide ring 111, the first end face 113b and the second end face 113c are the parts of the second water guide 113 closest to the center of the guide ring 111. The parts of the second water guide 113 other than the first end face 113b and the second end face 113c are lower than the first end face 113b and the second end face 113c. Thus, in the radial direction toward the center of the guide ring 111, the second water guide 113 can be roughly formed into a structure that is high at both ends and low in the middle. In this way, the condensate water agitated by the outdoor fan 14 flows circumferentially in the first flow channel 112a, and can change direction in the second flow channel 113a, flowing back to the guide ring 111 axially.

[0133] In some embodiments, please refer to Figure 3 and Figure 6 The position of the first end face 113b is flush with the inner wall surface of the guide ring 111.

[0134] In this embodiment, the first end face 113b will not protrude or be recessed radially relative to the inner wall surface of the guide ring 111. The first end face 113b can smoothly transition with the inner wall surface of the guide ring 111. This facilitates the reception of condensate from the first flow channel 112a and facilitates the return of condensate to the guide ring 111, reducing resistance and increasing the smoothness of condensate flow. Of course, it will not affect the air intake efficiency of the guide ring 111.

[0135] In some embodiments, please refer to Figure 3 and Figure 6 The position of the second end face 113c is flush with the inner wall surface of the guide ring 111.

[0136] In this embodiment, the second end face 113c will not protrude or be recessed radially relative to the inner wall surface of the guide ring 111. The second end face 113c can smoothly transition with the inner wall surface of the guide ring 111. This facilitates the reception of condensate from the first flow channel 112a and facilitates the return of condensate to the guide ring 111, reducing resistance and increasing the smoothness of condensate flow. Of course, it will not affect the air intake efficiency of the guide ring 111.

[0137] In some embodiments, please refer to Figure 3 and Figure 6 The end face of the second water guide 113 that is axially away from the guide ring 111 does not extend beyond the end face of the first water guide 112 that is axially away from the guide ring 111.

[0138] For example, the side end face of the second water guide 113 away from the guide ring 111 along the axial direction is flush with the side end face of the first water guide 112 away from the guide ring 111 along the axial direction.

[0139] In this embodiment, along the direction from the air outlet side to the air inlet side of the guide ring 111, the end face of the second water guide 113 will not exceed the end face of the first water guide 112. The second flow channel 113a can be located within the wind force range of the outdoor fan 14, which facilitates the second water guide 113 receiving the condensate from the first flow channel 112a and flowing it towards the air inlet side of the guide ring 111 under the action of the wind force, guiding the condensate back to the guide ring 111, reducing the probability of condensate dripping to the outside through the second flow channel 113a, and increasing the reliability of water guiding.

[0140] In some embodiments, please refer to Figure 3 and Figure 6 The sum of the circumferential dimensions of the first water guide 112 and the second water guide 113 does not exceed 1 / 4 of the circumferential dimension of the guide ring 111. For example, the sum of the circumferential dimensions of the first water guide 112 and the second water guide 113 is 1 / 4, 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, etc. of the circumferential dimension of the guide ring 111.

[0141] In this embodiment, the first water guide 112 and the second water guide 113 have small circumferential dimensions in the guide ring 111. On the one hand, it is not necessary to form an integral wrapping of the outdoor fan 14, which reduces the impact on the air intake efficiency of the outdoor fan 14. On the other hand, the first water guide 112 and the second water guide 113 occupy little space, which can also reduce production costs.

[0142] In some embodiments, please refer to Figure 3 and Figure 6 The first water guide 112 and the second water guide 113 are arranged along the height direction of the outdoor enclosure 11. That is, the first water guide 112 and the second water guide 113 have no overlap in the height direction. The first water guide 112 is located below the second water guide 113. When the outdoor fan 14 pumps condensate from below, it flows upward along the first water guide 112 to the second water guide 113. The second water guide 113 guides the condensate back to the guide ring 111 along the axis. In this way, the first water guide 112 is located in the bottom area of ​​the outdoor enclosure 11, which facilitates the rapid collection of condensate when the outdoor fan 14 pumps condensate, further reducing the chance of splashing.

[0143] The specific structure of the first water guide component 112 is not limited.

[0144] In some embodiments, please refer to Figure 3 and Figure 6The first water guide 112 includes a connecting plate 1121 and a baffle plate 1122. The second water guide 113 is connected to the periphery of the connecting plate 1121. One end of the connecting plate 1121 along the axial direction is connected to the flow guide ring 111, and the other end is connected to the baffle plate 1122. The baffle plate 1122 extends from the connection point with the connecting plate 1121 toward the direction close to the flow guide ring 111. The space between the baffle plate 1122 and the connecting plate 1121 defines the first flow channel 112a.

[0145] When the outdoor fan 14 rotates, the blades of the outdoor fan 14 can contact the baffle plate 1122, and the baffle plate 1122 can catch the condensate water stirred up by the outdoor fan 14 and keep it in the first flow channel 112a.

[0146] In this embodiment, the connecting plate 1121 connects the guide ring 111 and the baffle plate 1122 to reduce the impact on the outdoor fan 14. The baffle plate 1122 extends from the connection point with the connecting plate 1121 towards the guide ring 111, which can shield the condensate water and prevent the condensate water from splashing outward, thus achieving a good water blocking effect.

[0147] In some embodiments, please refer to Figure 3 and Figure 6 The inner wall surface of the connecting plate 1121 and the guide ring 111 are smoothly transitioned.

[0148] In this embodiment, the connecting plate 1121 will not protrude or be recessed relative to the guide ring 111, which can reduce the impact on the air intake efficiency of the outdoor fan 14. At the same time, it is also convenient to form a smooth structure for the flow of condensate water and smoothly connect with the second water guide 113, reducing flow resistance. Of course, it can also reduce manufacturing difficulty.

[0149] In some embodiments, please refer to Figure 3 and Figure 6 The baffle plate 1122 is formed into an arc-shaped structure, and the arc-shaped opening of the arc structure faces the air inlet side of the guide ring 111.

[0150] In this embodiment, the baffle plate 1122 is formed into an arc-shaped structure, which is convenient to adapt to the structure of the blades of the outdoor fan 14, reduce the rotational resistance of the outdoor fan 14, increase the smoothness of the rotation of the outdoor fan 14, and at the same time, reduce the flow resistance of condensate water, making it easier for condensate water to flow to the second water guide 113.

[0151] The specific structure of the second water guide 113 is not limited.

[0152] In some embodiments, please refer to Figure 3 and Figure 6The second water guide 113 includes a first plate 1131 and a second plate 1132. The first plate 1131 is connected to the first water guide 112 and the second plate 1132. One end of the first plate 1131 and the second plate 1132 along the axial direction is connected to the flow guide ring 111, and the other end of the first plate 1131 and the second plate 1132 along the axial direction extends away from the air inlet side of the flow guide ring 111. The space between the first plate 1131 and the second plate 1132 defines the second flow channel 113a. The first plate 1131 and the second plate 1132 are arranged at an angle.

[0153] Specifically, the first end face 113b is formed on the side end face of the first plate 1131 that is circumferentially away from the second plate 1132, and the second end face 113c is formed on the side end face of the second plate 1132 that is circumferentially away from the first plate 1131.

[0154] In this embodiment, the first plate 1131 and the second plate 1132 are arranged at an angle. On the one hand, this facilitates the avoidance of the outdoor fan 14 and guides the condensate to flow through the guide ring 111 under the action of the outdoor fan 14. On the other hand, it also facilitates the change of the flow direction of the condensate, reducing the probability of condensate splashing in the second flow channel 113a. At the same time, it facilitates the flow of condensate through the guide ring 111.

[0155] For example, please refer to Figure 3 and Figure 6 The plane of the first plate 1131 is perpendicular to the height direction of the outdoor enclosure 11, and the second plate 1132 is perpendicular to the first plate 1131. This makes it easier to change the flow direction of the condensate when the first plate 1131 receives the condensate from the first flow channel 112a, and to keep the condensate flowing approximately horizontally, further reducing the chance of splashing. At the same time, the condensate flows back to the guide ring 111 along the second plate 1132.

[0156] In some embodiments, please refer to Figure 3 and Figure 6 The first plate 1131 extends from the connection point with the first water guide 112 in a direction away from the center of the guide ring 111, and the second plate 1132 extends from the connection point with the first plate 1131 in a direction closer to the center of the guide ring 111.

[0157] Thus, the condensate flows from the first water guide 112 to the first plate 1131, flows at the first plate 1131 in a direction away from the center of the guide ring 111 to the second plate 1132, and then extends at the second plate 1132 in a direction closer to the center of the guide ring 111 to flow back to the guide ring 111.

[0158] In this embodiment, the first plate 1131 can smoothly receive condensate while keeping it away from the outdoor fan 14. The second plate 1132 can guide the condensate back to the guide ring 111 under the wind force of the outdoor fan 14. Thus, the water guiding efficiency is high, and no additional auxiliary structure is required. Of course, the structure of the first plate 1131 and the second plate 1132 is relatively simple and easy to form.
