Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a top-outlet air conditioning outdoor unit. Background Art

[0002] The top-outlet outdoor unit is a common type of air conditioner outdoor unit. In the top-outlet air conditioner outdoor unit, the casing air outlet is opened at the top of the outdoor unit, and the fan is located inside the casing and is arranged corresponding to the casing air inlet in the casing height direction, so that the air inside the casing is output from the casing air outlet to the outside of the casing through the operation of the fan. A fan cover is provided at the casing air outlet, and the fan is located below the fan cover and is usually connected to the fan cover, which undoubtedly puts high requirements on the strength of the fan cover. The fan cover needs to ensure that it is not easy to break under the action of the fan gravity to ensure the reliability of the fan operation.

[0003] In the prior art, some fan covers are manufactured by bending iron wire into a mesh structure. Not only are the processing steps relatively complicated, the processing efficiency is low, and the processing cost is high, but the fan cover itself has low strength and cannot well meet the strength requirements for the installation of the heat exchange fan. On the other hand, the fan cover and the top cover on the top of the casing mostly adopt a split structure, that is, the fan cover and the top cover are usually produced independently and then assembled together. Since the fan cover is subject to the gravity of the heat exchange fan, when the fan cover is assembled on the top cover, the assembly point of the top cover and the fan cover is easily damaged due to stress concentration, which reduces the strength of the top cover and causes the risk of the fan falling off.

[0004] In view of this, this application is filed. Utility Model Content

[0085] like Figure 1 and Figure 2 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 base. 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.

[0086] like Figure 4As 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 .

[0087] like Figure 3 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.

[0088] 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 .

[0089] In some embodiments, the heat exchange fan 400 is located below the air outlet 101 of the casing.

[0090] In some embodiments, the top cover 110 is connected to an air guide ring, which is arranged at the air outlet 101 of the casing; the interior of the air guide ring 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 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.

[0091] like Figure 5 As shown, the heat exchange fan 400 includes fan blades 410, and the fan blades 410 are used to promote air flow.

[0093] like Figure 4 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.

[0094] 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.

[0095] 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.

[0096] like Figure 1 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.

[0097] The fan cover 200 and the top cover 110 are integrally formed to increase the overall strength of the fan cover 200 so that the fan cover 200 can withstand a sufficiently large load and meet the requirement of working for a long time under harsh working conditions.

[0098] In some embodiments, the fan cover 200 and the top cover 110 are integrally formed by using a die stamping plate. The fan cover 200 and the top cover 110 are integrally formed by stamping the plate, which can simplify the production process, improve the processing efficiency, and reduce the processing cost.

[0099] In some embodiments, the dimension of the fan cover 200 along the height direction of the housing 100 is 1.5 mm.

[0100] like Figure 7 As shown, the fan cover 200 includes a connecting plate 210 , the connecting plate 210 is located in the middle part of the fan cover 200 , the heat exchange fan 400 is located below the connecting plate 210 , and the motor 420 is connected to the connecting plate 210 .

[0101] In some embodiments, the connecting plate 210 is circular.

[0102] The connecting plate 210 is detachably connected to the heat exchange fan 400 via fasteners 430, which are components such as bolts or screws; the heat exchange fan 400 is connected to the connecting plate 210 via fasteners 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.

[0103] like Fig. 9 As shown, the connecting plate 210 is provided with a connecting hole, which extends along the height direction of the housing 100 , and the fastener 430 passes through the connecting hole to be connected to the motor 420 .

[0104] In some embodiments, the number of fasteners 430 is four, and the four fasteners 430 are evenly distributed along the circumference, so that the connecting plate 210 and the motor 420 are evenly stressed, thereby increasing the firmness and reliability of the connection between the motor 420 and the connecting plate 210 .

[0105] When the number of the fasteners 430 is four, the number of the connecting holes is also correspondingly four, and the four connecting holes are evenly distributed on the connecting plate 210 along the circumference.

[0106] like Fig.12 As shown, a reinforcement portion 213 is provided on the side of the connecting plate 210 facing the accommodating cavity, the reinforcement portion 213 is arranged along the height direction of the casing 100, and the connecting hole is arranged through the reinforcement portion 213 along the height direction of the casing 100. The reinforcement portion 213 is used to increase the contact area between the fastener 430 and the connecting plate 210, thereby increasing the connection effect of the fastener 430 on the connecting plate 210 and the motor 420.

[0107] In some embodiments, one end of the fastener 430 is disposed outside the accommodating cavity, and the other end of the fastener 430 is connected to the motor 420 to achieve mutual connection between the motor 420 and the connecting plate 210 .

[0108] In order to hide the end of the fastener 430 disposed outside the accommodating cavity, as shown in FIG. Fig. 9 As shown, a sinking portion 212 is provided on the side of the connecting plate 210 away from the accommodating cavity, the sinking portion 212 is arranged corresponding to the reinforcing portion 213, the sinking portion 212 is recessed in the side of the connecting plate 210 away from the accommodating cavity, the connecting hole is arranged through the sinking portion 212 along the height direction of the casing 100, and the end of the fastener 430 away from the motor 420 is arranged in the sinking portion 212, so that the sinking portion 212 hides the end of the fastener 430 arranged outside the accommodating cavity, thereby increasing the aesthetics of the top-outlet air-conditioning outdoor unit.

[0109] Since the heat exchange fan 400 is connected to the connection plate 210 and is located below the connection plate 210 , the connection plate 210 is easily damaged under the gravity of the heat exchange fan 400 .

[0110] In order to increase the strength of the connecting plate 210, as Fig. 9 As shown, the connecting plate 210 is provided with a boss 211, and the boss 211 is arranged to protrude from the side of the connecting plate 210 away from the accommodating cavity.

[0111] In some embodiments, the boss 211 is located in the middle portion of the connecting plate 210 , and the sinking portion 212 is disposed on the boss 211 .

[0112] In some embodiments, the boss 211 is formed by the side of the connecting plate 210 facing the accommodating cavity protruding toward the top of the housing 100, and the side of the connecting plate 210 facing the accommodating cavity is provided with a recessed portion corresponding to the boss 211, and the recessed portion can increase the size of the accommodating cavity in the height direction of the housing 100. It should be noted that the reinforcing portion 213 is provided in the recessed portion.

[0113] In other embodiments, the sunken portion 212 is formed by a top surface of the boss 211 being recessed toward the accommodating cavity, a protrusion corresponding to the sunken portion 212 is formed in the recessed portion, and the reinforcing portion 213 is arranged on the protrusion, so that the connecting hole can pass through the sunken portion 212, the protrusion and the reinforcing portion 213 along the height direction of the casing 100, thereby ensuring that the fastener 430 can pass through the connecting hole and connect with the motor 420.

[0114] like Figure 8 As shown, the fan cover 200 includes a support frame 240 , one end of the support frame 240 in the length direction is connected to the connecting plate 210 , and the other end of the support frame 240 in the length direction is connected to the top cover 110 .

[0115] The connecting plate 210 and the top cover 110 are connected to each other by connecting one end of the supporting frame 240 to the connecting plate 210 and connecting the other end of the supporting frame 240 to the top plate.

[0116] like Figure 7 and Figure 8 As shown, the support frame 240 is provided with a reinforcing rib 230 , and the reinforcing rib 230 is protruding from the support frame 240 and arranged on the side away from the heat exchange blower 400 . The reinforcing rib 230 is used to increase the strength of the support frame 240 , thereby increasing the connection strength between the connecting plate 210 and the top cover 110 .

[0117] like Figure 7 As shown, the reinforcing ribs 230 extend to the connecting plate 210 along the length direction of the supporting frame 240 , and the reinforcing ribs 230 are arranged to penetrate the connecting plate 210 along the extending direction thereof, so as to increase the reinforcing effect of the reinforcing ribs 230 on the strength of the supporting frame 240 .

[0118] In some embodiments, Fig.11 As shown, the upper surface of the support frame 240 protrudes in a direction away from the accommodating cavity to form a reinforcing rib 230 , and a groove 231 corresponding to the reinforcing rib 230 is formed on the side of the support frame 240 facing the accommodating cavity.

[0119] In other embodiments, the upper surface of the support frame 240 is protruded in a direction away from the accommodating cavity by stamping to form the reinforcing rib 230. This method of producing the reinforcing rib 230 can simplify the production process of the reinforcing rib 230 and facilitate the manufacture of the reinforcing rib 230.

[0120] In some embodiments, four support frames 240 are provided, and the four support frames 240 are evenly distributed around the circumference to increase the connection strength between the connecting plate 210 and the top cover 110 .

[0121] like Figure 7 and Fig.10 As shown, the fan cover 200 includes an air outlet grille 220, which is arranged between the inner edge of the casing air outlet 101 and the connecting plate 210. The air outlet grille 220 defines an air outlet portion 250, and the air outlet portion 250 is connected to the casing air outlet 101. The air flowing out of the accommodating chamber from the casing air outlet 101 flows to the outdoors through the air outlet portion 250.

[0122] The air outlet grille 220 is connected to the supporting frame 240 , so that the air outlet grille 220 can be disposed between the inner edge of the air outlet 101 of the casing and the connecting plate 210 .

[0123] It should be noted that when the reinforcing ribs 230 are arranged on the upper surface of the protruding support frame 240 , the reinforcing ribs 230 can guide the airflow flowing out of the air outlet 250 , thereby reducing wind resistance and increasing air volume.

[0124] like Figure 8 As shown, the air outlet grille 220 includes a plurality of bars 221 , at least some of which are distributed along concentric circles in the same horizontal plane; an air outlet portion 250 is defined between adjacent bars 221 ; and the bars 221 are connected to the support frame 240 .

[0125] It should be noted that, since the bars 221 are distributed along concentric circles in the same horizontal plane, the length of the bars 221 close to the center of the distribution circle is shorter than the length of the bars 221 far from the center of the distribution circle.

[0126] When the connection plate 210 is circular, in some embodiments, the distribution center of the grid bars 221 and the center of the connection plate 210 are the same point.

[0127] It should be noted that the distribution center of the grid bars 221 refers to the center of the concentric circles when the grid bars 221 are distributed along the concentric circles. This is common knowledge in the art and will not be described in detail.

[0128] In some embodiments, the air outlet portion 250 is in the shape of an arc-shaped strip, which can effectively increase the air volume while ensuring the safety standards for the fingers of adults and children.

[0129] In some embodiments, the gaps between adjacent grille bars 221 are the same to ensure that the air outlet portion 250 has a larger ventilation area.

[0130] In some embodiments, the widths of the bars 221 are the same and smaller than the gaps between adjacent bars 221 to reduce the air blocking effect of the bars 221 and prevent the bars 221 from blocking air from flowing out of the air outlet 250 .

[0131] like Figure 8 and Fig. 9 As shown, a connector 222 is connected between at least some adjacent bars 221 , one end of the connector 222 is connected to the bar 221 , and the other end of the connector 222 is connected to the adjacent bar 221 . The adjacent bars 221 are connected by the connector 222 to increase the strength of the air outlet grille 220 .

[0132] The air outlet grille 220, the support frame 240, the connecting plate 210 and the top cover 110 are integrally formed to increase the strength of the fan cover 200, simplify the production process of the fan cover 200 and the top cover 110, and reduce the production cost.

[0133] like Fig.11 and Fig.12 As shown, the support frame 240 is provided with a connecting portion 241, one end of the connecting portion 241 is connected to the support frame 240, and the other end of the connecting portion 241 extends toward the heat exchange fan 400; the grid bar 221 is connected to the extended end of the connecting portion 241. It should be noted that the upper surface of the air outlet grille 220 is recessed in the upper panel of the connecting plate 210.

[0134] In some embodiments, the connecting portion 241 is formed by bending the outer edge of the support frame 240 downward. By flanging the support frame 240, the overall strength of the fan cover 200 and the top cover 110 after being integrally formed is increased, so that the fan cover 200 can still meet the working requirements of the fan cover 200 in bad weather.

[0135] In other embodiments, a connecting portion 241 is also provided at the inner edge of the casing air outlet 101 , one end of the connecting portion 241 is connected to the inner edge of the casing air outlet 101 , and the other end of the connecting portion 241 extends toward the heat exchange fan 400 .

[0136] In some other embodiments, the connection portion 241 of the inner edge of the air outlet 101 of the casing and the connection portion 241 of the supporting frame 240 are integrally formed.

[0137] like Fig. 9 and Fig.12 As shown, the fan cover 200 further includes a support member 223 , one end of the support member 223 in the length direction is connected to the connecting plate 210 , and the other end of the support member 223 in the length direction is connected to the top cover 110 ; the grille 221 is connected to the support member 223 .

[0138] By providing the support member 223 , on the one hand, the connection strength between the connecting plate 210 and the top cover 110 can be increased; on the other hand, the firmness and reliability of the setting of the grid bar 221 can be increased.

[0139] In some embodiments, four support members 223 are arranged, and the four support members 223 are evenly distributed along the circumference to increase the connection effect of the support members 223 on the bars 221 , and the connection effect of the support members 223 on the connection plate 210 and the top cover 110 .

[0140] When the number of the supporting skeletons 240 is also four, the four supporting skeletons 240 and the four supporting members 223 are staggered, and the connecting plate 210 is connected to the top cover 110 through the four supporting members 223 and the four supporting skeletons 240 , which can increase the connection strength between the connecting plate 210 and the top cover 110 .

[0141] It should be noted that, since the same bar 221 is connected to the support member 223 and the support frame 240, in some embodiments, the support member 223 and the support frame 240 divide the same bar 221 into multiple parts, and the bars 221 of the multiple parts are distributed along the same circumference.

[0142] like Figure 7 and Fig.13 As shown, the top cover 110 is provided with a protrusion 111, which is arranged on the upper surface of the top cover 110 and is arranged at the outer edge of the air outlet 101 of the casing. The protrusion 111 can increase the strength of the top cover 110; one end of the support frame 240 away from the connecting plate 210 is connected to the protrusion 111.

[0143] In some embodiments, the upper surface of the support frame 240 is flush with the upper surface of the protrusion 111 .

[0144] In some embodiments, since the protrusion 111 is disposed protruding from the upper surface of the top cover 110 and the reinforcing rib 230 is disposed protruding from the upper surface of the supporting frame 240, Fig.14 As shown, the outer edge of the top cover 110, the raised portion 111 and the reinforcing ribs 230 together form a multi-layer boss 211 structure to increase the strength of the fan cover 200 and the top cover 110, so that the fan cover 200 can still meet the strength requirements well in severe weather.

[0145] In other embodiments, the multi-layer boss 211 structure formed by the outer edge of the top cover 110, the protrusion 111 and the reinforcing ribs 230 is formed by stamping the plate, and the stamping method can facilitate the processing to form the protrusion 111 and the reinforcing ribs 230.

[0146] It should be noted that the multi-layer boss 211 structure formed by the outer edge of the top cover 110 , the raised portion 111 and the reinforcing ribs 230 is located at one end of the support frame 240 away from the connecting plate 210 .

[0147] It should also be noted that the fan cover 200 and the top cover 110 are respectively metal plates, and the grille 221, the connecting plate 210, the support frame 240, the support member 223, the protrusion 111, the reinforcing rib 230 and other components are formed by stamping the metal plates.

[0148] The air outlet principle of the above-mentioned top-outlet air-conditioning outdoor unit is as follows: the motor 420 drives the fan blades 410 to rotate, so that air enters the accommodating cavity from the casing air inlet 102, and after heat exchange with the outdoor heat exchanger 500, it is output to the outside of the accommodating cavity through the casing air outlet 101 and after being guided by the air outlet part 250.

[0149] The above-mentioned top-air-discharging air-conditioning outdoor unit is provided with a plurality of bars 221 distributed along concentric circles in the same horizontal plane, so that the plurality of bars 221 together form an air outlet grille 220, and the adjacent bars 221 define an air outlet portion 250, so that the air outlet portion 250 is in the shape of an arc-shaped long strip, which can increase the ventilation area and improve the air volume while ensuring the finger safety standards of adults and children.

[0150] The top-outlet air-conditioning outdoor unit is provided with a support frame 240, and the support frame 240 is used to connect the connecting plate 210 and the grid bar 221 to increase the overall strength of the fan cover 200; and a reinforcing rib 230 is provided on the support frame 240 to increase the strength of the support frame 240, thereby further increasing the overall strength of the fan cover 200. The reinforcing rib 230 is provided on the upper surface of the support frame 240, which can guide the airflow, reduce the resistance of the air flow, and thus increase the air output of the fan cover 200.

[0151] The above-mentioned top-air-discharging air-conditioning outdoor unit is designed to be an integral part of the fan cover 200 and the top cover 110 to increase the overall strength after the fan cover 200 and the top cover 110 are connected, so that the fan cover 200 can withstand a larger load and meet the requirements of the fan cover 200 working for a long time under harsh working conditions; by processing the fan cover 200 by using a mold stamping sheet, the processing steps can be reduced, the production efficiency of the fan cover 200 can be improved, and the processing cost can be reduced.
