[0056] As Figures 1 to 12As shown, according to an embodiment of the present utility model, an outdoor unit 100 of a heating, ventilation and air conditioning (HVAC) device is provided. The outdoor unit 100 of the HVAC device includes a box body 20 and a top cover assembly 10.

[0057] Specifically, the top cover assembly 10 is installed on the top of the box body 20. The box body 20 includes a main body, and a heat exchanger 30 and a compressor assembly 40 disposed inside the main body. Among them, the compressor assembly 40 is disposed inside the main body, the heat exchanger 30 is installed inside the main body and is disposed circumferentially around the compressor assembly 40. At this time, the top cover assembly 10 is located above the heat exchanger 30. In this embodiment, an impeller 13 is disposed inside the top cover assembly 10. At this time, the impeller 13 is located above the heat exchanger 30. Since the impeller 13 is located outside the heat exchanger 30, the inside of the box body 20 can communicate with the outside through a heat dissipation air duct on the side wall of the box body 20. The impeller 13 can rotate, and the rotation of the impeller 13 drives the air flow, enabling the outside air flow to enter the inside of the box body 20 through the heat dissipation air duct, and at the same time, enabling the air flow inside the box body 20 to be discharged to the outside through the top cover assembly 10.

[0058] It should be understood that, in this embodiment, as Figure 1 and Figure 2 shown, the impeller 13 is disposed above the heat exchanger 30, that is, the impeller 13 is disposed outside the heat exchanger 30, so that the size of the impeller 13 is not limited by the structural size of the heat exchanger 30. By increasing the size of the impeller 13, the driving ability of the impeller 13 for the air flow is improved, which helps to reduce the occurrence of air flow stagnation areas inside the outdoor unit 100 of the HVAC device, and effectively improves the heat exchange effect of the outdoor unit 100 of the HVAC device.

[0059] It should be further understood that, as Figure 2 and Figure 3As shown, a first working surface 21 is provided at the top of the box body 20. The top cover body 14 has a first communication port 143 that is inserted and cooperates with the top of the box body 20. Moreover, an air guide cover 15 is installed in the accommodation space of the top cover body 14. A second working surface 157 is provided at one end of the air guide cover 15 located at the first communication port 143. When the top cover assembly 10 is installed on the top of the box body 20, the first working surface 21 of the box body 20 and the bottom surface of the top cover body 14 are staggered, and the side wall of the box body 20 is adhesively connected to the side wall of the top cover assembly 10, so as to effectively reduce the occurrence of air leakage. At the same time, the first working surface 21 and the second working surface 157 are adjacently arranged, and a sealing member 16 is clamped therebetween. Since the sealing member 16 has a first compressed state, it helps to further reduce the outflow of air from the connection between the box body 20 and the top cover assembly 10, improve the sealing performance of the connection between the top cover assembly 10 and the box body 20, and thus help to avoid air leakage in the outdoor unit 100 of the HVAC equipment. In addition, it can effectively simplify the installation difficulty of the top cover assembly 10, improve the convenience of assembly, and facilitate subsequent disassembly, installation and maintenance.

[0060] In this embodiment, the top cover assembly 10 includes an air guide cover 15, a top cover body 14 and an impeller 13. The top cover assembly 10 includes an air guide cover 15, an impeller 13 and a top cover body 14 having an accommodation space. The top cover body 14 is arranged outside the box body 20 and fixedly connected to the top of the box body 20. The air guide cover 15 is arranged in the accommodation space of the top cover body 14. The impeller 13 is arranged in the air guide channel 155 of the air guide cover 15 and can rotate relative to the air guide channel 155. Among them, the outside can communicate with the heat exchanger 30 through the air guide channel 155.

[0061] It should be understood that the air guide channel 155 has an air inlet and an air outlet. When the impeller 13 rotates in the air guide channel 155, it can drive the air flow, so that the air flow enters the air guide channel 155 through the air inlet, and the air flow in the air guide channel 155 is discharged from the air guide channel 155 through the air outlet.

[0062] It should be noted that in the embodiment, when the impeller 13 rotates, under the drive of the impeller 13, the flow direction of the air flow is from the heat exchanger 30 to the impeller 13, that is, the air flow at the position of the heat exchanger 30 is drawn away by the rotation of the impeller 13, so that the air flow after heat exchange with the heat exchanger 30 is drawn out and the air flow that has not undergone heat exchange flows to the position of the heat exchanger 30, so as to realize the heat exchange between the flowing air flow and the heat exchanger 30.

[0063] In addition, the impeller 13 is arranged in the air guide channel 155 of the air guide cover 15, so that the impeller 13 can rotate in a relatively small space, so that the impeller 13 can increase the negative pressure formed during the rotation of the impeller 13 under the same rotation speed, thereby improving the driving ability of the airflow, so that the flow rate of the airflow is increased. It can also reduce the noise transmitted to the outside during the rotation of the impeller 13, so that the noise during the operation of the HVAC equipment outdoor unit 100 is effectively reduced.

[0064] Since the airflow needs to flow from the inside of the box 20 to the air guide channel 155, if there is air leakage at the connection between the top cover assembly 10 and the box 20, the flow rate of the airflow will be seriously affected, thereby affecting the heat exchange efficiency of the heat exchanger 30. In this embodiment, by staggering the first action surface 21 of the box 20 and the bottom surface of the top cover body 14, and using the installation compression seal 16 of the top cover assembly 10 and the box 20, the sealing of the connection between the top cover assembly 10 and the box 20 is enhanced, which helps to reduce the outflow of airflow from the connection between the box 20 and the top cover assembly 10, thereby helping to avoid air leakage in the outdoor unit 100 of the HVAC equipment.

[0065] Furthermore, a top surface and a first connecting port 143 are respectively provided on the top cover body 14, and the top surface is arranged away from the first connecting port 143. At this time, one end of the air guide channel 155 is connected to the first connecting port 143, and the top of the box body 20 is plugged into and matched with the first connecting port 143.

[0066] Specifically, the first communication port 143 of the top cover body 14 is plugged into the top of the box body 20 of the HVAC equipment outdoor unit 100. The plug-in matching method has a simple structure and can effectively optimize the structure, so that the manufacturing cost is effectively reduced. In addition, the plug-in matching method is easy to assemble, which can effectively improve the production efficiency and effectively reduce the production cost.

[0067] It should be pointed out that the top of the box body 20 and the first connecting port 143 are plugged in and matched, which means that the top of the box body 20 and the first connecting port 143 are plugged in each other, wherein the main body of the box body 20 with the top can be inserted into the first connecting port 143, or the first connecting port 143 can be inserted into the top of the box body. In the embodiment of the utility model, the top of the box body 20 is plugged in the first connecting port 143, and at this time, the second action surface 157 located at the top of the box body 20 is accommodated in the receiving space, and the first action surface 21 and the bottom surface of the top cover body 14 are staggered, and at the same time, the outer wall of the box body 20 is closely connected to the inner wall of the top cover body 14, thereby helping to reduce the outflow of airflow from the connection between the box body 20 and the top cover assembly 10, and ensuring the sealing of the outdoor unit 100 of the HVAC equipment.

[0068] Further, a second communication port 144 is formed on the top surface of the top cover body 14. At this time, the second communication port 144 and the first communication port 143 are located on opposite sides of the top cover body 14, and the accommodation space is communicatively connected between the second communication port 144 and the first communication port 143. The air guide cover 15 is disposed in the accommodation space of the top cover body 14. One end of the air guide channel 155 of the air guide cover 15 is communicatively connected to the first communication port 143, and the other end is communicatively connected to the outside through the second communication port 144.

[0069] Among them, the top cover assembly 10 is disposed on the top of the housing 20 of the outdoor unit 100 of the HVAC equipment. The first communication port 143 of the top cover body 14 is in plug-in fit with the top of the outdoor unit. The interior of the housing 20 is communicatively connected to the accommodation space of the top cover body 14 through the first communication hole, and is communicatively connected to the outside through the second communication port 144.

[0070] Specifically, the second communication port 144 is provided on the top cover body 14 so that the housing 20 can communicate with the outside through the first communication port 143 and the second communication port 144, thereby enabling the external air flow to exchange heat with the working components inside the housing 20, and further meeting the normal operation requirements of the outdoor unit 100 of the HVAC equipment.

[0071] It should be understood that the first communication port 143 and the second communication port 144 are opened on opposite sides of the top cover body 14, so that the air flow can flow in a straight line when flowing through the top cover body 14, reducing the influence on the air flow velocity and improving the heat exchange efficiency of the outdoor unit 100 of the HVAC equipment.

[0072] It should be noted that the top of the housing 20 of the HVAC equipment is an open structure. The first communication port 143 is communicatively connected to the open structure at the top of the housing 20. The interior of the housing 20 is communicatively connected to the outside through the first communication port 143, the accommodation space, and the second communication port 144.

[0073] In addition, the orifice shape of the first communication port 143 includes but is not limited to circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc., as long as it can be adaptively plugged into the top of the housing 20; similarly, the orifice shape of the second communication port 144 includes but is not limited to circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc.

[0074] In addition, the area of the flow cross-section of the first communication port 143 and the area of the flow cross-section of the second communication port 144 may be equal or unequal.

[0075] In some embodiments of the present utility model, in the top cover assembly 10, a mesh cover 11 is further included and installed on the top cover body 14. Among them, the second communication port 144 on the top cover body 14 is blocked by the mesh cover 11. By providing the mesh cover 11 at the second communication port 144, while enabling air flow exchange between the second communication port 144 and the outside, the second communication port 144 is blocked, thereby reducing the situation where external foreign objects fall into the interior of the top cover body 14 and the interior of the box body 20 through the second communication port 144.

[0076] It should be understood that the mesh cover 11 is fixedly connected to the top cover body 14, and the connection and fixation methods include but are not limited to screw connection, snap connection, buckle connection, riveting, bonding, welding, etc. In this embodiment, the mesh cover 11 is fixed on the top surface by screwing. Specifically, as Figure 7 shown, the side of the top cover body 14 facing away from the first communication port 143 is the top surface, and a groove 145 is formed on the top surface. Among them, the second communication port 144 is formed on the bottom surface of the groove 145. At the same time, the first communication port 143 and the second communication port 144 are arranged opposite to each other. At least a part of the body of the mesh cover 11 is received in the groove 145 in the direction from the first communication port 143 to the second communication port 144 and abuts against the bottom surface of the groove 145.

[0077] Among them, the shape of the groove 145 is adapted to the shape of the mesh cover 11. By providing the groove 145, the mesh cover 11 is limited by the groove 145, realizing the positioning and installation of the mesh cover 11, thereby improving the installation accuracy of the mesh cover 11. At the same time, in the direction from the first communication port 143 to the second communication port 144, part of the body of the mesh cover 11 can be arranged in the groove 145, or the entire body of the mesh cover 11 can be arranged in the groove 145.

[0078] It should be noted that by providing the groove 145 on the top surface of the top cover body 14, through the structural change, the strength of the top cover body 14 is further enhanced, thereby further improving the overall structural strength of the top cover body 14.

[0079] In addition, the mesh cover 11 has mesh holes, and the shapes of the mesh holes include but are not limited to circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc. Moreover, the mesh cover 11 can be a metal part or a non-metal part, and no further restrictions are imposed here.

[0080] It should be noted that connecting ribs 1422 are provided on the bottom surface of the groove 145. By using the connecting ribs 1422, the strength of the bottom surface can be increased, and the overall strength of the top cover assembly 10 is increased. In addition, the connecting ribs 1422 include but are not limited to rib plates, protruding structures or recessed structures, etc.

[0081] Still as Figure 2 andFigure 6 As shown, the top cover assembly 10 further includes a driving member 12. Among them, the mesh cover 11 of the top cover assembly 10 has a side face facing the second communication port 144, and the driving member 12 is fixedly installed on this side face. The impeller 13 is connected to the driving shaft of the driving member 12 and is rotatably arranged in the air guiding channel 155 of the air guiding cover 15.

[0082] Specifically, when the outdoor unit 100 of the heating and ventilation equipment operates, the driving member 12 rotates and drives the impeller 13 to rotate. During the rotation of the impeller 13, the air flow makes the air flow from the first communication port 143 to the second communication port 144, or makes the air flow from the second communication port 144 to the first communication port 143. The driving of the air flow is realized by using the impeller 13 and the driving member 12, thereby improving the heat exchange efficiency of the outdoor unit 100 of the heating and ventilation equipment.

[0083] It should be noted that, in this embodiment, the connection manner between the driving member 12 and the mesh cover 11 includes but is not limited to screw connection, snap connection, bonding, welding, riveting, etc. At the same time, the impeller 13, the first communication port 143, and the second communication port 144 are coaxially arranged. In addition, the driving member 12 includes but is not limited to a motor or a starting motor, etc.

[0084] Furthermore, there is a first distance d1 between the impeller 13 and the second acting surface 157, and there is a second distance d2 between the second acting surface 157 and the top surface, where 1 / 4d2 ≤ d1 ≤ 4 / 7d2.

[0085] Specifically, since the air flow moves in a straight line when flowing in the top cover body 14 and has a relatively fast flow rate, by further limiting the distance length between the impeller 13 and the second acting surface 157, the residence of the air flow at the connection between the box body 20 and the top cover assembly 10 can be effectively reduced, so that the air flow can flow quickly, which helps to further reduce the occurrence of air leakage. At the same time, limiting the distance between the impeller 13 and the second acting surface 157 to 1 / 4 - 4 / 7 of the distance between the second acting surface 157 and the top surface can further ensure the air flow effect.

[0086] It should be understood that, as Figure 6As shown, the first spacing d1 between the impeller 13 and the second acting surface 157 is the spacing between the lowest end of the impeller 13 and the second acting surface 157. At this time, the first spacing d1 is also the spacing between the impeller 13 and the first communication port 143. The second spacing d2 between the second acting surface 157 and the top surface is the depth of the accommodation space and also the depth of the air guiding channel 155. In this embodiment, the first spacing d1 > 0, that is, the impeller 13 is spaced from the second acting surface 157 (the first communication port 143). At this time, the air flow will quickly approach the impeller 13 under the action of the impeller 13 and flow out under the action of the impeller 13, and it is not easy to have the situation of air flow retention, which helps to reduce the occurrence of air leakage.

[0087] It should be noted that the impeller 13 is accommodated in the air guiding channel 155 of the air guiding cover 15. Since the air guiding cover 15 is arranged in the accommodation space of the top cover body 14, at this time, the top cover body 14 and the air guiding cover 15 can effectively protect the impeller 13, thereby avoiding the situation of deformation due to extrusion. At the same time, it can also make the top cover assembly 10 be carried as a whole component, and it is not easy to cause damage to the impeller 13 during the carrying process.

[0088] In some embodiments of the present utility model, as Figure 10 shown, the top cover body 14 is of a split structure, including side plates 142 and corner plates 141. Among them, the number of side plates 142 is at least one, and the number of corner plates 141 is at least one. The side plates 142 with the number of at least one enclose a cylindrical structure. Both ends of the cylindrical structure are open. One of the two openings of the cylindrical structure is the first communication port 143. The corner plates 141 are installed at the transition position of the other opening of the cylindrical structure and form the top surface, and the corner plates 141 and the side plates 142 enclose to form the second communication port 144.

[0089] By splitting the top cover body 14 into two parts, namely side plates 142 and corner plates 141, the processing difficulty can be reduced, thereby reducing the manufacturing cost, and at the same time, the yield rate of the top cover body 14 can be improved.

[0090] It should be noted that the corner plate 141 is a bent part, and the bending direction is towards the inner side of the top cover body 14. After the corner plate 141 is installed on the side plates 142 of the cylindrical structure, the bending position of the corner plate 141 constitutes a part of the groove 145 for accommodating the mesh cover 11.

[0091] When the number of side plates 142 is one, the side plate 142 is bent, and the two free ends after bending are connected and fixed by bonding or welding to form a cylindrical structure.

[0092] When the number of side plates 142 is more than one (two or more), by assembling all the side plates 142 (the connection methods at the assembly positions include but are not limited to screw connection, bonding, riveting, snap connection or welding, etc.), a cylindrical structure is formed. Setting multiple side plates 142 can further disassemble the structure, further reducing the difficulty in the manufacturing process.

[0093] In addition, when the number of corner plates 141 is one, the corner plate 141 is provided only at one corner position of the other opening (the opening facing away from the first communication port 143) of the cylindrical structure.

[0094] When the number of corner plates 141 is more than one (two or more), a corner plate 141 is provided at each corner position of the other opening (the opening facing away from the first communication port 143) of the cylindrical structure.

[0095] In this embodiment, the side plates 142 of the top cover body 14 enclose a cylindrical structure. The cylindrical structure has two opposite openings, one of which constitutes the first communication port 143 of the top cover body 14, and a flanging 1423 is provided at the other opening. The corner plate 141 of the top cover body 14 is provided at the corner position of the other opening of the cylindrical structure and is connected and fixed to the flanging 1423. By providing the flanging 1423, the contact area between the side plate 142 and the corner plate 141 is increased, enhancing the connection strength between the corner plate 141 and the side plate 142, and further improving the overall structural strength of the top cover body 14.

[0096] Furthermore, the air guide cover 15 includes a main body portion 151 and a shielding portion 152. Among them, the main body portion 151 is configured as a cylindrical structure, and an air guide channel 155 is opened along the axial direction of the cylindrical structure, and the air guide channel 155 is communicated with the opposite ends of the cylindrical structure. The shielding portion 152 is connected to the outer peripheral surface of the main body portion 151. The shielding portion 152 is correspondingly arranged corresponding to the corner positions of the top cover body 14 of the cylindrical structure, and a shielding portion 152 is provided at each corner position. The space between the top cover body 14 of the cylindrical structure and the main body portion 151 is shielded by the shielding portion 152. At the same time, the second acting surface 21 includes the side surface of the shielding portion 152 facing the box body 20.

[0097] Specifically, the top cover body 14 has a cylindrical structure, and the radial cross-section of this cylindrical structure is a rectangular structure, so that the structural strength and stability of the top cover body 14 can be improved. In this embodiment, since the top cover body 14 has four corners, the number of the shielding portions 152 is also four. The four shielding portions 152 are arranged at intervals along the circumferential direction of the outer peripheral surface of the main body portion 151 which is a cylindrical structure, and each corner of the top cover body 14 is correspondingly provided with a shielding portion 152. By providing the shielding portions 152, the space between the top cover body 14 which is a cylindrical structure and the main body portion 151 can be shielded, reducing the situation where air flow enters between the top cover body 14 and the air guide cover 15 (the air flow entering between the two is prone to stagnation), thereby reducing the situation where there are air flow stagnation areas in the outdoor unit 100 of the heating and ventilation equipment, and improving the heat exchange effect of the outdoor unit 100 of the heating and ventilation equipment.

[0098] It should be understood that the shielding portion 152 and the main body portion 151 can be an integral structure or a split structure. When the shielding portion 152 and the main body portion 151 are an integral structure, they can be processed and manufactured by an integral molding method. When the shielding portion 152 and the main body portion 151 are a split structure, they are first processed separately, and then the two are connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0099] It should be noted that along the axial direction of the main body portion 151 which is a cylindrical structure, all the shielding portions 152 can be located on the same circumferential surface or arranged at intervals. In the embodiment of the present utility model, all the shielding portions 152 are located on the same circumferential surface, so that the structural stability of the air guide cover 15 reaches the optimal effect, reducing the situation where the air guide cover 15 shakes due to the rotation of the impeller 13.

[0100] In addition, the shielding portion 152 can be connected or not connected to the inner wall of the top cover body 14 (the inner surface of the accommodation space). When they are connected, the shielding portion 152 is arranged in a fitting manner with the inner wall of the top cover body 14 and is connected by bonding, screw connection, welding, riveting or clamping. When they are not connected, the shielding portion 152 is arranged in a fitting manner with the inner wall of the top cover body 14. At the same time, the shape of the shielding portion 152 is adapted to the shape of the inner wall of the top cover body 14, thereby improving the shielding effect.

[0101] In addition, the above-mentioned second acting surface 157 can be the side surface of the main body portion 151 facing the box body 20, or can be composed of the side surface of the main body portion 151 facing the box body 20 and the side surface of the shielding portion 152 facing the box body 20, or can also be the side surface of the shielding portion 152 facing the box body 20. The setting of the second acting surface 157 can cooperate with the first acting surface 21 of the box body 20 to clamp the sealing member 16, thereby improving the sealing effect of the outdoor unit 100 of the heating and ventilation equipment, avoiding the air flow from flowing out at the connection between the box body 20 and the top cover assembly 10, thus preventing air leakage, and helping to improve the heat exchange effect of the outdoor unit 100 of the heating and ventilation equipment.

[0102] It should be noted that since the heat exchanger 30 is installed inside the main body and is arranged circumferentially around the compressor assembly 40, the top surface of the heat exchanger 30 and the top surface of the main body are located in the same plane and jointly form the first acting surface 21 of the box body 20. At this time, the above-mentioned sealing member 16 can be clamped between the main body and the air guide cover 15, or can also be arranged between the top surface of the heat exchanger 30 and the air guide cover 15. In this embodiment, the sealing member 16 is arranged between the top surface of the heat exchanger 30 and the air guide cover 15.

[0103] It should be further understood that the sealing member 16 is an elastic member, which can be a common rubber member 16, or sponge can also be used as the sealing member 16, so that when the box body 20 and the top cover assembly 10 are installed and fixed, it can be clamped by the first acting surface 21 and the second acting surface 157 and undergo compressive deformation. In this embodiment, the sealing member 16 is sponge and is compressed and arranged between the top of the heat exchanger 30 and the shielding portion 152 of the air guide cover 15.

[0104] In some embodiments of the utility model, as Figure 11 shown, a wire passing hole 156 for passing the connection wire of the driving member 12 is provided on the air guide cover 15. By providing the wire passing hole 156, it is convenient to lead out the connection wire of the driving member 12, improving the assembly convenience, and thus effectively improving the assembly efficiency. Moreover, the wire passing hole 156 is opened on the side wall of the air guide cover 15 and is arranged close to the driving member 12 to reduce the length of the connection wire in the air guiding channel 155 of the air guide cover 15, so as to reduce the influence of the connection wire on the air guiding channel 155.

[0105] It should be noted that the wire passing hole 156 includes but is not limited to round holes, square holes, diamond holes, triangular holes, oval holes, pentagonal holes or hexagonal holes, etc.

[0106] In some embodiments of the present utility model, as Figure 11 and Figure 12As shown in the figure, the air guide cover 15 further includes a connecting portion 153 connected to the outer peripheral surface of the main body portion 151. The shielding portion 152 and the connecting portion 153 are arranged at intervals along the axial direction of the cylindrical structure. The connection mode between the top cover body 14 of the cylindrical structure and the inner wall of the connecting portion 153 includes welding, bonding, clamping, riveting or screw connection.

[0107] Specifically, the connecting portion 153 is provided to connect and fix the air guide cover 15 and the top cover body 14 by using the connecting portion 153, so that the two become an integral structure, thereby improving the overall strength and reducing the shaking of the impeller 13 caused by poor structural strength during rotation, thereby improving the running stability of the impeller 13, and further effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0108] In addition, by setting the connection mode between the connecting portion 153 and the top cover body 14, the connection mode between the two can be set according to specific requirements, improving the flexibility of assembly. As a specific implementation manner, the connecting portion 153 includes a first fitting structure 1531 and a second fitting structure 1532. Among them, the first fitting structure 1531 is arranged on the outer peripheral surface of the main body portion 151 and is close to the side where the main body portion 151 is connected to the shielding portion 152. The first fitting structure 1531 is used for fixedly connecting with the side wall of the top cover body 14. The second fitting structure 1532 is arranged on the side of the main body portion 151 facing away from the shielding portion 152 for fixedly connecting with the top surface of the top plate body.

[0109] It should be understood that the connecting portion 153 and the main body portion 151 can be an integral structure or a split structure. When the connecting portion 153 and the main body portion 151 are an integral structure, they can be processed and manufactured by an integral molding method. When the connecting portion 153 and the main body portion 151 are a split structure, they are first processed separately and then connected and fixed by bonding, screw connection, welding, riveting or clamping. Preferably, the first fitting structure 1531 is a screw hole integrally formed on the main body to cooperate with the following mounting hole 1424 for connection. The second fitting structure 1532 is connected to the main body in a split manner, first processed separately, and then connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0110] In addition, in the embodiment, reinforcing portions 154 are provided at each of the shielding portion 152, the connecting portion 153, the main body portion 151, the connection position between the main body portion 151 and the connecting portion 153, and the connection position between the main body portion 151 and the shielding portion 152, so as to overall improve the structural strength of the air deflector 15. Meanwhile, the reinforcing portions 154 are dispersedly arranged on the air deflector 15, so that the structure of the air deflector 15 can be further made uniform, and the overall structural strength of the air deflector 15 can be further improved. Preferably, the reinforcing portion 154 includes at least one of a groove 145, a convex hull, and a rib plate.

[0111] Furthermore, a reinforcing structure 1421 is further provided on the top cover body 14, and the reinforcing structure 1421 is arranged between the top surface and the first communication port 143.

[0112] Specifically, the reinforcing structure 1421 is arranged between the top surface and the first communication port 143, wherein the distance between the reinforcing structure 1421 and the top surface is greater than the distance between the reinforcing structure 1421 and the first communication port 143. The first communication port 143 of the top cover body 14 is in plug-in fit with the top of the box body 20 of the outdoor unit 100 of the heating and ventilation equipment. By providing the reinforcing structure 1421 close to the first communication port 143 on the top cover body 14, the overall structural strength of the top cover assembly 10 is enhanced, thereby improving the structural strength of the connection position between the first communication port 143 and the box body 20, and further reducing the situation that the operation of the outdoor unit 100 of the heating and ventilation equipment is adversely affected due to the insufficient structural strength of the top cover assembly 10.

[0113] It should be understood that the top of the box body 20 is in plug-in fit with the top cover body 14. If the reinforcing structure 1421 is not provided on the top cover body 14, the self-strength of the top cover body 14 is relatively low, especially the connection position between the top cover body 14 and the box body 20. Therefore, the reinforcing structure 1421 is provided on the top cover body 14 and the position of the reinforcing structure 1421 is close to the first communication port 143, so as to improve the strength and stability of the connection position between the top cover body 14 and the box body 20.

[0114] In addition, the reinforcing structure 1421 refers to a structure formed on the top cover body 14, and this structure can be integrally formed with the top cover body 14 or can be separately processed and then installed and fixed on the top cover body 14. In the embodiment of the present utility model, the reinforcing structure 1421 is integrally formed with the top cover body 14, so as to reduce the processing procedures and effectively improve the production efficiency.

[0115] It should be noted that by providing a reinforcing structure 1421 on the top cover body 14, the air guide cover 15 can be made not to participate in weighing. At this time, the material of the air guide cover 15 can be optimized, which can not only reduce the mass of the air guide cover 15, but also effectively reduce the manufacturing cost of the air guide cover 15. For example, in the present utility model, the air guide cover 15 can be provided as a component formed of plastic or foam material.

[0116] In some embodiments of the present utility model, such as Figure 2 , Figure 3 and Figure 6 shown, the reinforcing structure 1421 is provided on the side plate 142 of the top cover body 14, and the reinforcing structure 1421 is provided as a concave structure.

[0117] Specifically, the reinforcing structure 1421 in the form of a concave structure is formed on the side wall of the top cover body 14. Among them, the reinforcing structure 1421 in the form of a concave structure is formed on the outer surface or the inner surface of the top cover body 14. When the concave structure is formed on the outer surface of the top cover body 14, it can be a groove 145 structure formed on the outer surface of the top cover body 14, or a concave structure formed by recessing from the outer surface of the top cover body 14 towards the inner surface; when the convex structure is formed on the inner surface of the top cover body 14, it can be a groove 145 structure formed on the inner surface of the top cover body 14, or a concave structure formed by recessing from the inner surface of the top cover body 14 towards the outer surface.

[0118] In addition, the reinforcing structure 1421 in the form of a concave structure is arranged close to the first communication port 143 of the top cover body 14. Among them, when the concave structure is formed by recessing, a structure adapted to the concave structure is provided at the position of the top of the box body 20 corresponding to the reinforcing structure 1421 for concave-convex cooperation, thereby increasing the contact area between the top cover assembly 10 and the box body 20, and further increasing the connection strength and stability between the top cover assembly 10 and the box body 20.

[0119] In addition, when the outer surface of the top cover body 14 has a groove 145 structure or a convex structure is formed on the outer surface due to the formation of a concave structure on the inner surface, when installing the top cover assembly 10, the assembler can hold the convex structure or dig at the position of the concave structure, which improves the convenience of lifting the top cover assembly 10 during assembly and effectively improves the assembly efficiency.

[0120] It should be noted that the reinforcing structure 1421 can be provided not only as a concave structure, but also as a convex structure. When provided as a convex structure, its construction method can refer to the form of the concave structure and will not be elaborated here. At the same time, setting the reinforcing structure 1421 as a convex structure is more convenient for handling.

[0121] It should be understood that since the reinforcing structure 1421 is set as a concave structure or a convex structure, it enables the operator to hold or pick it with the hand. At this time, while increasing the structural strength of the top cover body 14, the reinforcing structure 1421 can also be used as a handle, thereby improving the convenience of the top cover assembly 10.

[0122] At this time, it should be noted that the handle is arranged on the outer side wall of the top cover body 14. In addition to being a concave structure or a convex structure formed on the top plate body 14, it can also be a split structure with the top cover body 14. At this time, the handle and the top cover body can be connected and fixed by means such as bonding, screw connection, welding, riveting or clamping, and no more restrictions are imposed here.

[0123] It should be pointed out that when the handle and the top cover body 14 are of a split structure, the shape of the handle can adopt existing common structures, and no more restrictions are imposed here. At the same time, the number of handles can also be set to multiple to facilitate the convenience of disassembly and assembly. The position of the handle is optimally set so as not to affect the structural strength of the top cover body 14 and the convenience of disassembly and assembly.

[0124] It should be further understood that as Figure 6 shown, the top cover body 14 further includes a mounting member 17, and the mounting member 17 is mounted on the concave structure and is screwed to the first mating structure 1531 of the air guide cover 15.

[0125] Specifically, by arranging the mounting member 17 on the concave structure and screwing it to the first mating structure 1531 of the air guide cover 15, the fixed connection between the top plate body and the air guide cover 15 on the side can be effectively ensured, and the two are made into an integral structure, which helps to improve the overall strength and reduce the shaking of the impeller 13 caused by poor structural strength during rotation or handling, thereby improving the running stability of the impeller 13, and further effectively improving the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0126] It should be understood that as Figure 8 and Figure 9 shown, on the side wall of the top plate body, that is, on the side plate 142, a concave structure is provided, and a mounting hole 1424 is provided on the bottom surface of the concave structure. The axial direction of the mounting hole 1424 is perpendicular to the axial direction of the cylindrical structure. At the same time, the above-mentioned mounting member 17 is set as a screw or a bolt, and the mounting member 17 passes through the mounting hole 1424 and is screwed to the first mating structure 1531. At this time, the first mating structure 1531 is a screw hole formed on the main body portion 151. Such a setting helps to simplify the installation difficulty between the top plate body and the air guide cover 15 and ensure the connection strength between the top plate body and the air guide cover 15. At the same time, since the mounting hole 1424 is provided on the bottom surface of the concave structure, the aesthetics of the outdoor unit 100 of the HVAC equipment is effectively improved while ensuring the structural strength of the top plate body.

[0127] In some embodiments of the present utility model, the number of the strengthening structures 1421 provided on the top cover body 14 is one. One strengthening structure 1421 is arranged along the circumference of the first communication port 143, and one strengthening structure 1421 can cover a part of the circumference of the first communication port 143 or can cover the entire circumference of the first communication port 143.

[0128] In some embodiments of the present utility model, as Figures 7 to 10 shown, a plurality of strengthening structures 1421 are provided on the top cover body 14. Along the circumference of the top cover body 14, all the strengthening structures 1421 are arranged at intervals.

[0129] Specifically, in this embodiment, the number of the strengthening structures 1421 is set to be a plurality, so that the strengthening structures 1421 can be arranged according to different structural shapes of the top cover body 14, and the overall structural strength of the top cover body 14 can be effectively enhanced by the strengthening structures 1421.

[0130] It should be noted that a plurality of strengthening structures 1421 are arranged at intervals along the circumference of the top cover body 14, and the circumference of the top cover body 14 is the same as the circumference of the first communication port 143. Among them, a plurality of strengthening structures 1421 can cover a part of the circumference of the first communication port 143 or can cover the entire circumference of the first communication port 143.

[0131] As Figures 1 to 12 shown, a second aspect of the present utility model provides a heating and ventilation device, and the heating and ventilation device includes the outdoor unit 100 of the heating and ventilation device as above.

[0132] For the heating and ventilation device according to the present utility model, the top cover body 14 of the outdoor unit 100 of the heating and ventilation device is arranged on the top of the box body 20, the heat exchanger 30 is arranged inside the box body 20. At this time, the top cover body 14 is located outside the heat exchanger 30, the air guide cover 15 is arranged in the receiving space of the top cover body 14, and the heat exchanger 30 can communicate with the outside through the air guide cover 15. At this time, the impeller 13 can be arranged outside the heat exchanger 30, so that the size of the impeller 13 is not limited by the structural size of the heat exchanger 30, thereby improving the driving ability of the impeller 13 for the air flow, and thus reducing the problem of the air flow stagnation area in the outdoor unit 100 of the heating and ventilation device.

[0133] Meanwhile, the first communication port 143 of the top cover body 14 is inserted and cooperated with the top of the box body 20, so that the first working surface 21 of the box body 20 and the first communication port 143 of the top cover body 14 are staggered, and the side wall of the box body 20 is attached and connected to the side wall of the top cover assembly 10, which not only helps to reduce the difficulty of disassembly and assembly, but also can effectively reduce the occurrence of air leakage. At the same time, a seal 16 is clamped between the second working surface 157 of the air guide cover and the first working surface 21 of the box body 20, so as to further reduce the outflow of air from the connection between the box body 20 and the top cover assembly 10, improve the sealing performance of the connection between the top cover assembly 10 and the box body 20, and thus help to further avoid the occurrence of air leakage in the outdoor unit 100 of the HVAC equipment.

[0134] In some embodiments of the present invention, the above-mentioned HVAC equipment is an air conditioner (in other embodiments of the present invention, the HVAC equipment includes, but is not limited to, multi-connected units, heat pumps, water heaters, pool machines, etc.). For the structures of other parts of the air conditioner, please refer to the prior art, and details will not be described herein.

[0135] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
