[0071] The top-outlet air-conditioning outdoor unit provided in the present application may have various implementation forms. Figure 1-Figure 15 It is a specific implementation of the top-outlet air-conditioning outdoor unit of the present application.

[0072] like Figure 1 As shown, the top-outlet air-conditioning outdoor unit provided in the present application includes a casing 100, and the casing 100 is used to form the overall appearance of the air-conditioning outdoor unit; the top of the casing 100 and the bottom of the casing 100 are opposite ends, and the height direction of the casing 100 is from the bottom of the casing 100 to the top of the casing 100; the left side of the casing 100 and the right side of the casing 100 are opposite sides, and the length direction of the casing 100 is from the left side of the casing 100 to the right side of the casing 100; the front side of the casing 100 and the rear side of the casing 100 are opposite sides, and the thickness direction of the casing 100 is from the front side of the casing 100 to the rear side of the casing 100.

[0073] The casing 100 includes a casing air outlet 101 . The casing air outlet 101 is disposed at the top of the casing 100 . The air inside the casing 100 is output to the outside through the casing air outlet 101 .

[0074] In some embodiments, the opening of the housing air outlet 101 is arranged to face upward.

[0075] The casing 100 includes a casing air inlet 102 . The casing air inlet 102 is disposed at the outer periphery of the casing 100 , and outdoor air enters the casing 100 through the casing air inlet 102 .

[0076] In some embodiments, the opening direction of the casing air inlet 102 is arranged to intersect with the opening direction of the casing air outlet 101 .

[0077] like Figure 1 and Figure 2 As shown, the housing 100 includes a top cover 110 , which is located at the top of the housing 100 , and a housing air outlet 101 is opened in the top cover 110 .

[0078] In some embodiments, the air outlet 101 of the housing is circular in opening direction and is disposed in the middle portion of the top cover 110 .

[0079] like Figure 1-Figure 3 As shown, the housing 100 includes a side panel 120 , which is connected to the top cover 110 . The side panel 120 is located below the top cover 110 , and the housing air inlet 102 is opened on the side panel 120 .

[0080] like Figure 1 As shown, the housing 100 includes a bottom plate 130, which is disposed below the side plate 120. The bottom plate 130 and the top cover 110 are disposed correspondingly along the height direction of the housing 100. The bottom plate 130, the side plate 120 and the top cover 110 define a receiving cavity together. The receiving cavity is used to receive components such as an outdoor heat exchanger 500, a compressor 600 and a heat exchange fan 400 disposed inside the housing 100; wherein the housing air inlet 102 and the housing air outlet 101 are respectively connected to the receiving cavity.

[0081] In some embodiments, the bottom plate 130 is a rectangular structure with cut corners, and the housing 100 is a substantially cubic structure.

[0082] like Figure 1 As shown, the top-outlet air-conditioning outdoor unit includes an electric control box 300, which is installed on the housing 100 and located outside the accommodating cavity. The electric control box 300 is arranged above the cut corner of the chassis 130. The electric control box 300 is provided with electrical components required for the operation of the air-conditioning outdoor unit, which belongs to the prior art in the field and will not be described in detail.

[0083] like Figure 3As shown, the top-outlet air-conditioning outdoor unit includes an outdoor heat exchanger 500 , which is disposed inside the casing 100 and is used to exchange heat for the air inside the casing 100 ; the outdoor heat exchanger 500 is disposed close to the casing air inlet 102 , and the outdoor heat exchanger 500 is installed on the chassis 130 .

[0084] like Figure 2 As shown, the top-outlet air conditioner outdoor unit includes a heat exchange fan 400, which is located in the accommodating cavity and is arranged near the housing air outlet 101. Through the operation of the heat exchange fan 400, outdoor air enters the accommodating cavity through the housing air inlet 102, contacts the outdoor heat exchanger 500, and is output to the outdoors through the housing air outlet 101.

[0085] In some embodiments, the heat exchange fan 400 is an axial flow fan, and the heat exchange fan 400 and the casing air outlet 101 are arranged correspondingly along the height direction of the casing 100 .

[0086] In some embodiments, the heat exchange fan 400 is located below the air outlet 101 of the casing.

[0087] In some embodiments, the top cover 110 is connected to an air guide ring 111, which is disposed at the air outlet 101 of the casing; the interior of the air guide ring 111 defines a through cavity extending along the height direction of the casing 100, and at least part of the heat exchange fan 400 is located in the through cavity. The air guide ring 111 is used to guide the air flow in the accommodating cavity so that the heat exchange fan 400 can better play the role of inducing air.

[0088] like Figure 4 As shown, the heat exchange fan 400 includes fan blades 410, and the fan blades 410 are used to promote air flow.

[0089] like Figure 4 and Figure 6 As shown, the heat exchange fan 400 includes a motor 420, and the fan blades 410 are connected to the output shaft of the motor 420. The motor 420 is located below the top cover 110, and the output shaft of the motor 420 is set downward. The motor 420 is used to drive the fan blades 410 to rotate.

[0090] like Figure 3 As shown, the top-outlet air-conditioning outdoor unit includes a compressor 600, which is arranged inside the casing 100 and mounted on the chassis 130. The compressor 600 is used to compress the refrigerant in a low-temperature and low-pressure state into a high-temperature and high-pressure state. The compressor 600, the outdoor heat exchanger 500 and the indoor heat exchanger together form a refrigerant circulation loop, and the refrigerant flows in the refrigerant circulation loop to achieve cooling or heating of the indoor environment by the air conditioner.

[0091] The compressor 600 is arranged in the middle part of the chassis 130, and the outdoor heat exchanger 500 is arranged at the outer edge part of the chassis 130. The outdoor heat exchanger 500 is arranged around the outer periphery of the compressor 600. On the one hand, the area of ​​the outdoor heat exchanger 500 can be increased, and the heat exchange effect of the outdoor heat exchanger 500 can be increased; on the other hand, the outdoor heat exchanger 500 can be arranged close to the air inlet 102 of the casing, so that the air entering the casing 100 can contact the outdoor heat exchanger 500 in time, thereby increasing the heat exchange effect of the outdoor heat exchanger 500.

[0092] The compressor 600 is located below the heat exchange fan 400 so that the heat exchange fan 400 can be arranged close to the air outlet 101 of the casing.

[0093] like Figure 4 As shown, the top-outlet air-conditioning outdoor unit includes a fan cover 200, which is disposed at the air outlet 101 of the housing and connected to the top cover 110. The fan cover 200 is used to provide protection for the heat exchange fan 400 and the fan blades 410 to prevent damage to the fan or accidental injury caused by inhalation of indoor debris. The fan cover 200 can also concentrate and evenly guide the wind flow, making the air flow blown out by the fan more concentrated and even.

[0094] like Figure 4 and Figure 5 As shown, the fan cover 200 includes an air outlet grille 220, which is arranged at the casing air outlet 101. The air outlet grille 220 defines an air outlet portion, which is connected to the casing air outlet 101; the air in the accommodating chamber is output from the casing air outlet 101 through the air outlet grille 220 to the outside of the accommodating chamber.

[0095] like Figure 5 As shown, the fan cover 200 includes a connecting plate 210 , which is located in the middle part of the fan cover 200 , the connecting plate 210 is arranged on the top of the air outlet grille 220 , the heat exchange fan 400 is located below the connecting plate 210 , and the motor 420 is connected to the connecting plate 210 .

[0096] The connecting plate 210 is detachably connected to the heat exchange fan 400 via a connecting piece 430, and the connecting piece 430 is a component such as a bolt or a screw; the heat exchange fan 400 is connected to the connecting plate 210 via the connecting piece 430, so that the heat exchange fan 400 can be arranged in the accommodating cavity and located below the air outlet 101 of the casing.

[0097] The connecting plate 210 is provided with a connecting hole, which extends along the height direction of the housing 100. The connecting member 430 passes through the connecting hole and the air outlet in sequence to be connected with the heat exchange fan 400.

[0098] In some embodiments, the connection plate 210 is square.

[0099] In some embodiments, there are four connecting members 430 and four connecting holes, which are correspondingly arranged at the four corners of the connecting plate 210 so that the connecting plate 210 and the motor 420 are subjected to uniform force, thereby increasing the firmness and reliability of the connection between the motor 420 and the connecting plate 210.

[0100] Since the heat exchange fan 400 is connected to the connecting plate 210 and the connecting plate 210 is located above the air outlet grille 220 , at least part of the weight of the heat exchange fan 400 will be transferred to the air outlet grille 220 , which places higher requirements on the strength of the air outlet grille 220 .

[0101] like Figure 6-Figure 9 As shown, the air outlet grille 220 includes a frame 223 , which is mounted on the top cover 110 and is disposed at the outer edge of the air inlet 102 of the casing.

[0102] In some other embodiments, the frame 223 is surrounded by wires to form a closed square.

[0103] like Figure 7 As shown, the air outlet grille 220 includes a first support member 221, which is connected to the frame 223; the first support member 221 is configured as a plurality of first support members 221, and at least some of the first support members 221 are distributed along a first direction; wherein the first direction is a horizontal direction.

[0104] In some embodiments, the diameter of the first support member 221 is 3 mm.

[0105] In some embodiments, the first support member 221 is an iron wire, so that the first support member 221 has a higher strength.

[0106] In some embodiments, the first support member 221 is welded to the frame 223 to increase the connection strength between the first support member 221 and the frame 223 .

[0107] There needs to be a certain gap between adjacent first support members 221 so that the air passing through the housing air outlet 101 can be output to the outside of the accommodation cavity through the gap between adjacent first support members 221. When the gap is too large, fingers can easily extend into the accommodation cavity through the gap, causing safety hazards, and the gap is too large and it is easy to reduce the strength of the air outlet grille 220; when the gap is too small, the first support member 221 has a strong blocking effect on the air, which can easily reduce the air outlet area of ​​the air outlet grille 220, thereby reducing the air outlet volume of the air outlet grille 220.

[0108] In some embodiments, the gap between adjacent first support members 221 is 9 mm to prevent the air outlet portion of a finger from extending into the accommodating cavity and to enable the air outlet grille 220 to have a larger air outlet area and air outlet volume.

[0109] In some embodiments, the lengths and diameters of the plurality of first support members 221 are the same, so as to improve the adaptability of the first support members 221 , reduce the number of processing steps during the processing, and improve the processing efficiency.

[0110] In some embodiments, the first support member 221 is disposed on a side of the frame 223 away from the accommodating cavity, so that the frame 223 supports the first support member 221 , thereby increasing the connection reliability between the first support member 221 and the frame 223 .

[0111] like Figure 9-12 As shown, the air outlet grille 220 includes a second support member 224 , which is connected to the frame 223 ; the second support member 224 and the first support member 221 are arranged to cross each other to increase the strength of the air outlet grille 220 .

[0112] The second support members 224 are configured in plurality, and at least some of the second support members 224 are distributed along the second direction; the second direction and the first direction are both horizontal directions, and the second direction intersects with the first direction.

[0113] By connecting the first support member 221 and the second support member 224 to the frame 223 respectively, the frame 223 constrains and fixes the first support member 221 and the second support member 224, so that the first support member 221 and the second support member 224 can be reliably cross-arranged with each other, thereby increasing the strength of the air outlet grille 220.

[0114] In some embodiments, the diameter of the first support member 221 is less than or equal to the diameter of the second support member 224 , so that the second support member 224 is an important supporting framework of the air outlet grille 220 .

[0115] In some embodiments, the diameter of the second support member 224 is 8.6 mm.

[0116] In some embodiments, Fig.12 As shown, in some embodiments, the number of the second support members 224 is at least five, so that the second support members 224 have a better supporting effect on the first support members 221 , thereby increasing the strength of the air outlet grille 220 .

[0117] There is a certain gap between adjacent second support members 224 so that the air passing through the casing air outlet 101 can be output to the outside of the accommodating cavity through the gap between adjacent second support members 224. If the gap is too small, the second support member 224 will block the gap between adjacent first support members 221, reducing the air outlet area and air outlet volume of the air outlet grille 220.

[0118] It should be noted that when the second support members 224 play a major supporting role for the air outlet grille 220, the number of the second support members 224 is usually less than the number of the first support members 221. When the gap between adjacent first support members 221 is 9 mm, fingers can no longer be inserted into the accommodating cavity through the gap. At this time, the gap between adjacent second support members 224 does not need to be set too much.

[0119] It should also be noted that the gap between adjacent first support members 221 and the gap between adjacent second support members 224 together define a wind outlet.

[0120] In some embodiments, the second support member 224 is an iron wire, so that the second support member 224 has a higher strength.

[0121] In some embodiments, the second support member 224 is welded to the frame 223 to increase the connection strength between the second support member 224 and the frame 223 .

[0122] In some embodiments, the first support member 221 is disposed on the top of the second support member 224 , so that the second support member 224 supports the first support member 221 .

[0123] In some embodiments, the second support member 224 is disposed in the frame 223 to increase the connection strength between the second support member 224 and the frame 223 .

[0124] In some embodiments, the lengths and diameters of the plurality of second support members 224 are the same, so as to improve the adaptability of the second support members 224 , reduce the number of processing steps during the processing, and improve the processing efficiency.

[0125] In order to increase the connection strength between the connecting plate 210 and the air outlet grille 220, the connecting plate 210 is arranged above at least part of the intersection of the first support plate and the second support plate, so that the first support plate and the second support plate can support the connecting plate 210, so that the gravity of the heat exchange fan 400 can be shared by the first support plate and the second support plate, thereby increasing the connection strength between the connecting plate 210 and the air outlet grille 220.

[0126] like Fig.11 and Fig.12 As shown, the air outlet grille 220 includes a reinforcement member 222 , which is connected to a frame 223 to increase the strength of the air outlet grille 220 .

[0127] In some embodiments, at least one reinforcement member 222 is provided to increase the strength enhancement effect of the reinforcement member 222 on the air outlet grille 220 .

[0128] When there is one reinforcement member 222, the reinforcement member 222 is arranged at the middle part of the frame 223 along the first direction, so that the reinforcement member 222 can have a better reinforcement effect on the air outlet grille 220; when there are multiple reinforcement members 222, the multiple reinforcement members 222 are distributed along the first direction.

[0129] In some embodiments, the reinforcement member 222 is disposed on a side of the air outlet grille 220 facing the accommodating cavity to further increase the strength of the air outlet grille 220 .

[0130] It should be noted that since the first support member 221 and the reinforcement member 222 are respectively arranged on opposite sides of the frame 223, the reinforcement member 222 may be arranged corresponding to the gap between two adjacent first support members 221, thereby blocking the air. In order to solve this problem, in some embodiments, there is a larger gap between two adjacent first support members 221, and the reinforcement member 222 is arranged between two adjacent first support members 221 to prevent the reinforcement member 222 from blocking the gap between the two adjacent first support members 221 in the height direction of the casing 100.

[0131] In some embodiments, the reinforcement member 222 is a wire.

[0132] In some embodiments, the length direction of the reinforcement member 222 is set along the second direction, the length direction of the first support member 221 is set along the second direction, and the length direction of the second support member 224 is set along the first direction, so that the reinforcement member 222 and the first support member 221 are respectively cross-arranged with the second support member 224.

[0133] like Fig.13 As shown, the top cover 110 is provided with a sunken portion 112, which is recessed in the upper surface of the casing 100; the casing air outlet 101 is arranged through the sunken portion 112 along the height direction of the casing 100, and the air outlet grille 220 is located in the sunken portion 112, so that the sunken portion 112 hides the air outlet grille 220, thereby increasing the aesthetics of the outdoor unit.

[0134] In this embodiment, the air outlet grille 220 is roughly quadrilateral, and the four corners of the air outlet grille 220 are respectively provided with a first connecting portion 2241, and the sinking portion 112 is provided with a second connecting portion 113, and the second connecting portion 113 is arranged corresponding to the first connecting portion 2241; the first connecting portion 2241 and the second connecting portion 113 are connected with the same fastener to connect the air outlet grille 220 and the top cover 110 to each other.

[0135] It should be noted that the fasteners are components such as bolts or screws.

[0136] In some embodiments, the first connection part 2241 is provided with a first connection hole, the second connection part 113 is provided with a second connection hole, the second connection hole is arranged corresponding to the first connection hole, and the fastener is simultaneously arranged in the first connection hole and the second connection hole to connect the air outlet grille 220 and the top cover 110 to each other.

[0137] In some embodiments, the size of the sinking portion 112 in the horizontal plane is larger than the opening size of the casing air outlet 101 in the horizontal plane. When the second connecting portion 113 and the first connecting portion 2241 are connected to each other through fasteners, the sinking portion 112 supports the outer edge of the air outlet grille 220 to increase the connection strength between the air outlet grille 220 and the top cover 110.

[0138] like Fig. 9 As shown, the first connection portion 2241 is disposed on the second support member 224 , and the second connection portion 113 is disposed on the outer edge of the air outlet 101 of the casing.

[0139] Since the first connection portion 2241 is disposed on the second support member 224, and the second support member 224 is disposed at the bottom of the first support member 221, the first support member 221 may interfere with the first connection portion 2241. Fig. 9 As shown, the first support member 221 is provided with an avoidance portion 2211, and the avoidance portion 2211 is arranged corresponding to the first connection portion 2241. The fastener passes through the avoidance portion 2211 and is arranged at the first connection portion 2241 to prevent the first support member 221 from interfering with the fastener connecting the air outlet grille 220 and the top cover 110.

[0140] It should be noted that when there are multiple second support members 224, not all second support members 224 need to be provided with the first connection portion 2241, and the first connection portion 2241 is only provided on the second support member 224 corresponding to the corner of the air outlet grille 220 to meet the installation requirements of the air outlet grille 220. Similarly, not all first support members 221 need to be provided with the avoidance portion 2211, and the avoidance portion 2211 is only provided on the first support member 221 corresponding to the first connection portion 2241 to meet the requirements.

[0141] In some embodiments, the avoiding portion 2211 is formed by bending the first supporting member 221 close to the first connecting portion 2241 along the first direction toward a direction away from the first connecting portion 2241 .

[0142] The working principle of the above-mentioned top-outlet air-conditioning outdoor unit is as follows: by operating the heat exchange fan 400, outdoor air is introduced into the accommodating cavity through the casing air inlet 102, and after heat exchange through the outdoor heat exchanger 500, it is output to the outside of the accommodating cavity through the casing air outlet 101 through the air outlet grille 220.

[0143] The above-mentioned top-air-discharging air-conditioning outdoor unit is configured by cross-arranging the first support member 221 and the second support member 224, and using the frame 223 to constrain and fix the first support member 221 and the second support member 224, so that the first support member 221, the second support member 224 and the frame 223 are connected to each other to form an air outlet grille 220; by arranging the first support member 221 at the top of the frame 223, so that the frame 223 supports the first support member 221, thereby increasing the reliability and firmness of the connection between the first support member 221 and the frame 223, thereby increasing the strength of the air outlet grille 220.

[0144] The above-mentioned top-outlet air-conditioning outdoor unit is provided with a reinforcement member 222, and the reinforcement member 222 is connected to the frame 223 to increase the strength of the frame 223; the reinforcement member 222 and the first support member 221 are arranged on opposite sides of the frame 223, and the gap between the two first support members 221 arranged corresponding to the reinforcement member 222 is increased, so that the reinforcement member 222 is arranged between the two first support members 221, so as to prevent the reinforcement member 222 from affecting the air outlet effect.

[0145] The top-outlet air-conditioning outdoor unit can prevent fingers from being inserted into the accommodating cavity through the gap by setting the gap between two adjacent first support members 221 to 9 mm, while ensuring that the air outlet grille 220 has a large air outlet area and air outlet volume.

[0146] The above-mentioned top-air outlet air-conditioning outdoor unit arranges the connecting plate 210 at the partial intersection of the first support member 221 and the second support member 224 so that the first support member 221 and the second support member 224 can share the weight of the heat exchange fan 400 on the connecting plate 210, thereby increasing the supporting effect of the air outlet grille 220 on the connecting plate 210.

[0147] The top-outlet air-conditioning outdoor unit is designed such that the diameters and lengths of the plurality of first support members 221 are designed to be the same size, and the diameters and lengths of the plurality of second support members 224 are designed to be the same size, so as to improve the adaptability between the first support members 221 and between the second support members 224, reduce the processing steps in the processing, and improve the processing efficiency.

[0148] The above-mentioned top-air-discharging air-conditioning outdoor unit is provided with a sinking portion 112 on the top cover 110 so that the air outlet grille 220 is arranged in the sinking portion 112, thereby preventing the air outlet grille 220 from protruding from the top of the top cover 110, thereby ensuring the aesthetics of the air-conditioning outdoor unit; and a first connecting portion 2241 is provided at the four corners of the air outlet grille 220, and a second connecting portion 113 is provided at the corresponding position of the sinking portion 112, so that the fasteners are sequentially provided in the first connecting portion 2241 and the second connecting portion 113, so that the air outlet grille 220 is installed on the top cover 110, thereby reducing the hidden danger of deformation caused by the small contact area between the air outlet grille 220 and the top cover 110.
