Description

Technical Field

[0001] The utility model relates to the technical field of HVAC equipment, and particularly relates to a top cover assembly, an outdoor unit of HVAC equipment, and HVAC equipment. Background Art

[0002] In the existing outdoor unit of HVAC equipment, its top cover assembly integrates corresponding functional components (such as a fan, etc.), and the corresponding functional components operate to meet the operating requirements of the HVAC equipment. When the outdoor unit of HVAC equipment is operating, the blades rotate to achieve heat exchange between the heat exchanger and the external air flow.

[0003] In the prior art, the wind blades of the top cover component are located on the lower side of the top cover. After installation, both sides of the wind blades are easily squeezed and deformed, and it is inconvenient to repair. Moreover, the heat exchangers of the outdoor unit of HVAC equipment are mostly arranged radially outside the wind blades, so that the size of the wind blade is limited by the size of the heat exchanger, affecting the air volume of the wind blade. Summary of the Utility Model

[0004] The purpose of the utility model is to at least solve the problems that the wind blades of the existing outdoor unit of HVAC equipment are easily damaged and not easy to repair. This purpose is achieved by the following technical solutions:

[0053] As Figures 1 to 10 As shown, according to an embodiment of the present utility model, a top cover assembly 10 for an outdoor unit 100 of a heating, ventilation, and air conditioning (HVAC) device is provided. The top cover body 14 is configured to be mounted on the top of a heat exchanger 30 of the outdoor unit 100 of the HVAC device. The top cover body 14 has a first communication port 143 and a second communication port 144, and a receiving space communicating the first communication port 143 and the second communication port 144. The first communication port 143 and the second communication port 144 are located on opposite sides of the top cover body 14. The first communication port 143 is configured to be plugged and mated with the top of a cabinet 20 of the outdoor unit 100 of the HVAC device. The receiving space communicates with the outside through the second communication port 144. At this time, a mesh cover 11 is disposed on the top cover body 14 and covers the second communication port 144. Blades 13 are rotatably disposed on the mesh cover 11 and are located in the receiving space. A first distance d1 is provided between the blades 13 and the first communication port 143, and a second distance d2 is provided between the first communication port 143 and the second communication port 144, where 1 / 4d2 ≤ d1 ≤ 4 / 7d2.

[0054] As Figures 1 to 3As shown, when the top cover assembly 10 is used for the outdoor unit 100 of the HVAC equipment, the first communication port 143 of the top cover body 14 is inserted and cooperated with the top of the box body 20 of the outdoor unit 100 of the HVAC equipment. By arranging the blades 13 on the mesh cover 11 and being able to be installed and fixed with the mesh cover 11 in the accommodating space of the top cover body 14, a certain length is formed between the blades 13 and the first communication port 143. At this time, by limiting the distance between the blades 13 and the first communication port 143, the top cover body 14 and the air guide cover 15 can effectively protect the blades 13, thus avoiding the situation of deformation caused by 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 damage the blades 13 during the handling process.

[0055] It should be understood that since the air flow moves in a straight line when flowing through the top cover body 14 and has a relatively fast flow rate, by limiting the blades 13 to be arranged on the mesh cover 11 and located in the accommodating space, the top cover assembly 10 can be made into a whole component, which is not only beneficial to the packaging of the outdoor unit 100 of the HVAC equipment, but also can protect the blades, thus avoiding being squeezed during the use process or the handling process. At the same time, it can also effectively reduce the residence of the air flow at the connection between the box body 20 and the top cover assembly 10, so that the air flow can flow quickly, which helps to further reduce the occurrence of air leakage.

[0056] It should be pointed out that the top cover assembly 10 is installed on the top of the box body 20, the compressor assembly 40 is arranged in the box body 20, and the heat exchanger 30 is installed inside the box body 20 and is arranged circumferentially around the compressor assembly 40. At this time, the top cover assembly 10 is located above the heat exchanger 30. In this embodiment, the blades 13 are arranged inside the top cover assembly 10. At this time, the blades 13 are located above the heat exchanger 30. Since the blades 13 are located outside the heat exchanger 30, the inside of the box body 20 can communicate with the outside through the heat dissipation air duct on the side wall of the box body 20. The blades 13 can rotate, and the rotation of the blades 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, discharging the air flow inside the box body 20 to the outside through the top cover assembly 10.

[0057] It needs to be further understood that as Figure 1 and Figure 2 shown, arranging the blades 13 above the heat exchanger 30, that is, arranging the blades 13 outside the heat exchanger 30, enables the size of the blades 13 not to be limited by the structural size of the heat exchanger 30. By increasing the size of the blades 13, the driving ability of the blades 13 for the air flow is improved, which helps to reduce the situation of air flow stagnation areas in the outdoor unit 100 of the HVAC equipment, and effectively improves the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0058] Still as Figure 2 andFigure 3 As shown, a first acting surface 21 is provided at the top of the box body 20, a first communication port 143 is provided at the bottom of the top cover body 14, a second communication port 144 is provided at the top of the top cover body 14, and a receiving space communicating the first communication port 143 and the second communication port 144. A wind guide cover 15 is installed in the receiving space. A second acting surface 157 is provided at one end of the wind guide cover 15 close to the first communication port 143. When the top cover assembly 10 is installed on the top of the box body 20, the first acting surface 21 of the box body 20 is staggered with the bottom surface of the top cover body 14, and the side wall of the box body 20 is attached and connected to the side wall of the top cover assembly 10, so as to effectively reduce the occurrence of air leakage.

[0059] At this time, the first acting surface 21 and the second acting surface 157 are arranged adjacent to each other, and a sealing ring 16 is clamped therebetween. Since the sealing ring 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 helps 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 and maintenance.

[0060] It should be further understood that the blades 13 are rotatably arranged on the mesh cover 11 and are located in the receiving space. Among them, there is a first distance d1 between the blades 13 and the first communication port 143, and a second distance d2 between the first communication port 143 and the second communication port 144, where d1 = 1 / 4 - 4 / 7d2.

[0061] Specifically, since the air flow moves in a straight line when flowing through the top cover body 14 and has a relatively fast flow rate, by further limiting the length of the distance between the blades 13 and the first communication port 143, 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 blades 13 and the first communication port 143 to 1 / 4 - 4 / 7 of the distance between the first communication port 143 and the second communication port 144 can further ensure the flow effect of the air flow.

[0062] It should be understood that as Figure 6As shown, there is a first spacing d1 between the blade 13 and the second acting surface 157. At this time, the first spacing d1 is the spacing between the lowest end of the blade 13 and the second acting surface 157, and is also the spacing between the blade 13 and the first communication port 143. There is a second spacing d2 between the second acting surface 157 and the top surface. At this time, the second spacing d2 is the distance between the first communication port 143 and the second communication port 144, and is also the depth of the accommodation space or the depth of the air guiding channel 155. In this embodiment, the first spacing d1 > 0, that is, the blade 13 and the second acting surface 157 (the first communication port 143) are spaced apart. At this time, the blade 13 is accommodated in the air guiding channel 155 of the air guiding cover 15, so that it can be protected by the top cover body 14 and the air guiding cover 15, and is prevented from being deformed 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 damage the blade 13 during the carrying process.

[0063] It should be noted that since the air flow will quickly approach the blade 13 under the action of the blade 13 and flow out under the action of the blade 13, when the blade 13 and the second acting surface 157 (the first communication port 143) are spaced apart, air flow stagnation is not likely to occur inside the top cover body 14, which helps to reduce the occurrence of air leakage.

[0064] In some embodiments of the present invention, as Figure 6 and Figure 10 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, a 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 part of the body of the mesh cover 11 is accommodated 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.

[0065] Specifically, 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.

[0066] It should be noted that the mesh cover 11 is fixedly connected to the top cover body 14, and the connection and fixing methods include but are not limited to screw connection, clamping connection, snap connection, riveting, bonding, welding, etc.

[0067] In addition, the mesh cover 11 can be a metal part, and can be processed by welding or casting during processing; the mesh cover 11 can also be a non-metal part, such as plastic, and can be integrally formed by injection molding during processing.

[0068] 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.

[0069] It should be understood that in the direction from the first communication port 143 to the second communication port 144, part of the main body of the mesh cover 11 can be arranged in the groove 145, or the entire main body can be arranged in the groove 145. In this embodiment, part of the main body of the mesh cover 11 is arranged in the groove 145. At the same time, screw holes are provided on the top surface, and mounting holes 111 are formed on the mesh cover 11. The mesh cover 11 can be mounted on the top surface through screw connectors, which not only has a simple structure but also helps with the disassembly and assembly of the mesh cover 11 on the top cover body 14.

[0070] In addition, 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. By providing the groove 145 on the top surface of the top cover body 14, with the change in structure, the strength of the top cover body 14 is further enhanced, thereby further improving the overall structural strength of the top cover body 14.

[0071] It should be further understood that the mesh cover 11 is installed in the groove 145 at the top of the top cover body 14, and the installation position of the mesh cover 11 is limited by the groove 145, so that the installation position of the blade 13 can be limited, reducing the noise generated by the blade 13 during operation due to vibration and other reasons.

[0072] In some embodiments of the present invention, 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.

[0073] Furthermore, as Figure 3 and Figure 5 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 surface facing the first communication port 143, and the driving member 12 is fixedly installed on this side surface. The blade 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.

[0074] Specifically, when the outdoor unit 100 of the HVAC equipment operates, the driving member 12 rotates to drive the blade 13 to rotate. During the rotation of the blade 13, the air flow is caused to flow from the first communication port 143 to the second communication port 144, or the air flow is caused to flow from the second communication port 144 to the first communication port 143. The driving of the air flow is achieved by using the blade 13 and the driving member 12, thereby improving the heat exchange efficiency of the outdoor unit 100 of the HVAC equipment.

[0075] It should be understood that in this embodiment, the blade 13 and the driving member 12 form an axial flow fan structure, that is, the air flow enters and exits along the axial direction of the blade 13. In addition, under the drive of the blade 13 and the driving member 12, the air flow flows from one side of the first communication port 143 to one side of the second communication port 144.

[0076] It should be noted that the connection method 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 blade 13, the first communication port 143, and the second communication port 144 are coaxially arranged.

[0077] In addition, the driving member 12 includes but is not limited to an electric motor or a starting motor, etc.

[0078] Furthermore, the mesh cover 11 is arranged as a grid structure, and a connecting component 18 is arranged on the mesh cover. The connecting component 18 is fixedly connected to the driving member 12.

[0079] Specifically, by arranging the mesh cover 11 as a grid structure, it helps to improve the structural strength of the mesh cover 11, enabling it to install the driving member 12 and not easily deform. By arranging the connecting component 18 to cooperate with the structure of the mesh cover 11, not only can the connection strength between the driving member 12 and the mesh cover 11 be ensured, but also it helps to reduce the installation difficulty between the driving member 12 and the mesh cover 11 and ensure the assembly efficiency.

[0080] It should be understood that the mesh cover 11 includes a plurality of transverse plates and a plurality of longitudinal plates. Among them, the transverse plates and the longitudinal plates are cross-connected to form a grid structure. A hole-shaped installation structure is provided in the middle of the grid structure to be able to cooperate with the connecting component 18 for installation and fixation, and to make the driving member 12 coaxial with the air guiding channel 155. At the same time, on the mesh cover 11, and circumferentially along the installation hole structure, screw holes are provided. The screw holes are formed at the intersections of the transverse plates and the longitudinal plates, which not only helps to ensure the strength of the mesh cover 11 but also can ensure the connection effect between the mesh cover 11 and the top cover body 14.

[0081] It should be noted that the mesh cover 11 can also be arranged in other shapes, such as circular, square, pentagonal, hexagonal, triangular, elliptical, rhombic, etc., as long as it can ensure the ventilation of the mesh cover 11 and the installation of the connecting component 18.

[0082] Further, the connecting component 18 includes a first part 181 and a second part 182. The first part 181 and the second part 182 are respectively arranged on opposite sides of the mesh cover 11 and clamp the mesh cover 11, and the driving member 12 is fixedly connected to the second part 182.

[0083] Specifically, by setting the connecting component 18 as the first part 181 and the second part 182, and the two cooperate and are capable of clamping the mesh cover 11, not only can the fixing effect of the connecting component 18 on the mesh cover 11 be effectively guaranteed, but also it helps to cooperate with the installation structure to ensure the coaxiality of the driving member 12 and the air guiding channel 155. The structure is simple, the operation is convenient, and it is convenient for the disassembly and assembly of the driving member 12 and the blades 13.

[0084] It should be understood that the first part 181 and the second part 182 are fixedly installed through a screwing member. At the same time, the first part 181 passes through the installation structure of the mesh cover 11 and extends to the side of the mesh cover 11 close to the air guiding channel 155, so as to ensure that the axis of the driving member 12 and the axis of the air guiding channel 155 are on the same straight line. The installation is simple and easy to operate, and the accuracy is good.

[0085] It should be noted that the connection method between the first part 181 and the second part 182 can also adopt snap connection, buckle connection, riveting, bonding, welding, etc. in addition to screwing.

[0086] In addition, in addition to adopting the cooperation structure in which the first part 181 passes through the mesh cover 11, it can also be set that the second part 182 passes through the mesh cover 11 to cooperate with the first part 181. Through the installation structure of the mesh cover 11, it cooperates with the first part 181 or the second part 182 for installation. On the one hand, it can be beneficial for the driving shaft of the driving member 12 and the air guiding channel 155 to be on the same axis, and it is also convenient for the installation of the connecting component 18 and the installation of the driving member 12. It is simple and fast, and the assembly effect is good.

[0087] In addition, a marking structure can be formed on the first part 181 on the side of the mesh cover 11 facing away from the air guiding cover 15. The marking structure can be a disassembly marking, a warning or a product marking. Of course, the marking structure can also be other components such as an instruction manual.

[0088] Further, the top cover assembly 10 further includes an air guiding cover 15. The top cover body 14 is arranged outside the box body 20 and is fixedly connected to the top of the box body 20. The air guiding cover 15 is arranged in the receiving space of the top cover body 14. The blades 13 are arranged in the air guiding channel 155 of the air guiding cover 15 and can rotate relative to the air guiding channel 155. Among them, the outside can be communicated with the heat exchanger 30 through the air guiding channel 155.

[0089] It should be understood that the air guide channel 155 has an air inlet and an air outlet. When the blade 13 rotates in the air guide channel 155, it can drive the airflow so that the airflow enters the air guide channel 155 through the air inlet, and the airflow in the air guide channel 155 is discharged from the air guide channel 155 through the air outlet.

[0090] It should be pointed out that, in the embodiment, when the blades 13 rotate, driven by the blades 13, the flow direction of the airflow is from the heat exchanger 30 to the blades 13, that is, the airflow at the position of the heat exchanger 30 is extracted by the rotation of the blades 13, so that the airflow after heat exchange with the heat exchanger 30 is extracted and the airflow that has not undergone heat exchange flows to the position of the heat exchanger 30, so as to realize heat exchange between the flowing airflow and the heat exchanger 30.

[0091] In addition, by arranging the blade 13 in the air guide channel 155 of the air guide cover 15, the blade 13 can rotate in a relatively small space, so that the blade 13 can increase the negative pressure formed during the rotation of the blade 13 under the same rotation speed condition, 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 blade 13, so that the noise during the operation of the HVAC equipment outdoor unit 100 is effectively reduced.

[0092] 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 ring 16 of the top cover assembly 10 and the box 20, the sealing performance 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.

[0093] It needs to be further understood that 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.

[0094] 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.

[0095] It should be noted that the top of the box body 20 being inserted and fitted with the first communication port 143 means that the top of the box body 20 and the first communication port 143 are inserted into each other. Among them, it can be that the main body of the top of the box body 20 is inserted into the first communication port 143, or the first communication port 143 is inserted into the top of the box body. In the embodiment of the present utility model, the top of the box body 20 is inserted into the first communication port 143. At this time, the second acting surface 157 located at the top of the box body 20 is accommodated in the receiving space, and the first acting surface 21 and the bottom surface of the top cover body 14 are arranged in a staggered manner. At the same time, the outer side wall of the box body 20 is in close connection with the inner side wall of the top cover body 14, which helps to reduce the outflow of air from the connection between the box body 20 and the top cover assembly 10 and ensures the sealing performance of the outdoor unit 100 of the HVAC equipment.

[0096] It should be further understood that by providing the second communication port 144 on the top cover body 14, the box body 20 can communicate with the outside through the first communication port 143 and the second communication port 144, so that the external air flow can exchange heat with the working components inside the box body 20, thereby meeting the normal operation requirements of the outdoor unit 100 of the HVAC equipment. At the same time, 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 on 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.

[0097] It should be noted that the top of the box body 20 of the HVAC equipment is an open structure, the first communication port 143 is connected to the open structure of the top of the box body 20, and the inside of the box body 20 communicates with the outside through the first communication port 143, the receiving space, and the second communication port 144.

[0098] 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 inserted with the top of the box body 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.

[0099] 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 can be equal or unequal.

[0100] In some embodiments of the present utility model, such as Figure 8As shown, the top cover body 14 is a split structure, including a side panel 142 and a corner panel 141, wherein the number of the side panel 142 is at least one, the number of the corner panel 141 is at least one, and the at least one side panel 142 forms a cylindrical structure with openings at both ends of the cylindrical structure, one of the two openings of the cylindrical structure is a first connecting port 143, the corner panel 141 is installed at the transition position of the other opening of the cylindrical structure and forms a top surface, and the corner panel 141 and the side panel 142 together form a second connecting port 144.

[0101] By splitting the top cover body 14 into two parts, namely the side plate 142 and the angle plate 141 , the difficulty of processing 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.

[0102] It should be pointed out that the corner plate 141 is a bent part, and the bending direction is bent toward the inner side of the top cover body 14 . After the corner plate 141 is installed on the side plate 142 of the cylindrical structure, the bent position of the corner plate 141 constitutes a part of the groove 145 for accommodating the mesh cover 11 .

[0103] When the number of the side plate 142 is one, the side plate 142 is bent and the two free ends after the bending are connected and fixed by bonding or welding, so as to form a cylindrical structure.

[0104] When there are multiple side panels 142 (two or more), a cylindrical structure is formed by assembling all side panels 142 (the connection methods of the assembly positions include but are not limited to screw connection, bonding, riveting, snap connection or welding, etc.). Providing multiple side panels 142 can further split the structure, so that the difficulty of the manufacturing process is further reduced.

[0105] Furthermore, when the number of the angle plate 141 is one, the angle plate 141 is provided only at one corner position of the other opening of the cylindrical structure (the opening facing away from the first communication port 143 ).

[0106] When there are multiple (two or more) angle plates 141 , one angle plate 141 is provided at each corner position of the other opening of the cylindrical structure (the opening away from the first communication port 143 ).

[0107] 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 is provided on the other opening. The gusset plates 141 of the top cover body 14 are arranged at the corner positions of the other opening of the cylindrical structure and are connected and fixed to the flanging. By providing the flanging, the contact area between the side plates 142 and the gusset plates 141 is increased, so that the connection strength between the gusset plates 141 and the side plates 142 is enhanced, and the overall structural strength of the top cover body 14 is further improved.

[0108] 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 arranged in a cylindrical structure, and the 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, and the shielding portion 152 is correspondingly arranged at the corner positions of the top cover body 14 of the cylindrical structure, and a shielding portion 152 is respectively arranged 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.

[0109] Specifically, the top cover body 14 is in a cylindrical structure, and the radial cross-section of the 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 of the cylindrical structure, and each corner of the top cover body 14 is correspondingly provided with a shielding portion 152. By providing the shielding portion 152, the space between the top cover body 14 of the cylindrical structure and the main body portion 151 can be shielded, and the situation of air flow entering between the top cover body 14 and the air guide cover 15 (the air flow entering between the two is prone to stagnation) can be reduced, so that the situation of air flow stagnation areas in the outdoor unit 100 of the heating and ventilation equipment is reduced, and the heat exchange effect of the outdoor unit 100 of the heating and ventilation equipment is improved.

[0110] 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 means of bonding, screw connection, welding, riveting or clamping.

[0111] 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 can be 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 guiding cover 15 reaches the optimal effect, reducing the situation that the air guiding cover 15 shakes due to the rotation of the blades 13.

[0112] In addition, the shielding portion 152 and the inner wall of the top cover body 14 (the inner surface of the receiving space) can be connected or not connected to each other. When they are connected, the shielding portion 152 is arranged in close fit 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 close fit 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.

[0113] 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. 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 ring 16, thereby improving the sealing effect of the outdoor unit 100 of the heating and ventilation equipment and preventing air flow from flowing out from the connection between the box body 20 and

[0114] the top cover assembly 10, so as to avoid the situation of air leakage and contribute to improving the heat exchange effect of the outdoor unit 100 of the heating and ventilation equipment.

[0115] It should be understood that the sealing ring 16 is an elastic member, which can be a common rubber sealing ring 16 or can also use sponge as the sealing ring 16, so that it can be clamped by the first acting surface 21 and the second acting surface 157 and undergo compressive deformation when the box body 20 and the top cover assembly 10 are installed and fixed.

[0116] In some embodiments of the utility model, as Figure 9 shown, a wire passing hole 156 for passing the connecting wire of the driving member 12 is provided on the air guiding cover 15. By providing the wire passing hole 156, it is convenient to lead out the connecting wire of the driving member 12, improving the convenience of assembly, and thus effectively improving the assembly efficiency. Moreover, the wire passing hole 156 is opened on the side wall of the air guiding cover 15 and is arranged close to the driving member 12 to reduce the length of the connecting wire in the air guiding channel 155 of the air guiding cover 15 and reduce the influence of the connecting wire on the air guiding channel 155.

[0117] 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.

[0118] In some embodiments of the present invention, Figure 9 and Figure 10 As shown, the air guide cover 15 also includes a connecting portion 153 connected to the outer peripheral surface of the main body 151, and the shielding portion 152 and the connecting portion 153 are arranged at intervals along the axial direction of the cylindrical structure. The connection method 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.

[0119] Specifically, a connecting portion 153 is provided, and the connecting portion 153 is used to connect and fix the air guide cover 15 and the top cover body 14, so that the two become an integral structure, thereby improving the overall strength and reducing the shaking of the blade 13 during rotation due to the difference in structural strength, thereby improving the stability of the operation of the blade 13, and further effectively improving the heat exchange effect of the HVAC equipment outdoor unit 100.

[0120] In addition, by setting the connection method between the connection part 153 and the top cover body 14, the connection method between the two can be set according to specific needs, thereby improving the flexibility of assembly. As a specific implementation, the connection part 153 includes a first matching structure 1531 and a second matching structure 1532, wherein the first matching structure 1531 is arranged on the outer peripheral surface of the main body 151 and close to the side where the main body 151 is connected to the shielding part 152, and the first matching structure 1531 is used to be fixedly connected to the side wall of the top cover body 14. The second matching structure 1532 is arranged on the side of the main body 151 away from the shielding part 152, so as to be fixedly connected to the top surface of the top plate body.

[0121] It should be understood that the connection portion 153 and the main body 151 can be an integral structure or a split structure. When the connection portion 153 and the main body 151 are an integral structure, they can be processed and manufactured by an integral molding method. When the connection portion 153 and the main body 151 are split structures, they are first processed separately, and then the two are connected and fixed by bonding, screw connection, welding, riveting or clamping. Preferably, the first matching structure 1531 is integrally formed with the screw connection hole on the main body to match the following mounting hole for connection. The second matching structure 1532 is connected to the main body in a split manner, and is first processed separately, and then the two are connected and fixed by bonding, screw connection, welding, riveting or clamping.

[0122] 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. At the same time, 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.

[0123] Furthermore, a reinforcing structure 1421 is further provided on the top cover body 14, and the reinforcing structure 1421 is provided between the top surface and the first communication port 143.

[0124] Specifically, the reinforcing structure 1421 is provided between the top surface and the first communication port 143. Among them, 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 inserted and cooperated 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 near 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.

[0125] It should be understood that the top of the box body 20 is inserted and cooperated 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.

[0126] In addition, the reinforcing structure 1421 refers to a structure formed on the top cover body 14. 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.

[0127] It should be noted that by providing the strengthening 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.

[0128] In some embodiments of the present utility model, such as Figure 2 , Figure 3 and Figure 6 shown, the strengthening structure 1421 is provided on the side plate 142 of the top cover body 14, and the strengthening structure 1421 is provided as a concave structure.

[0129] Specifically, the strengthening structure 1421 in the form of a concave structure is formed on the side wall of the top cover body 14. Among them, the strengthening 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.

[0130] In addition, the strengthening structure 1421 in the form of a concave structure is provided 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 strengthening 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.

[0131] Furthermore, when the outer surface of the top cover body 14 has a groove 145 structure or has a convex structure 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.

[0132] It should be noted that the strengthening structure 1421 can also be provided as a convex structure in addition to being provided as a concave structure. When it is provided as a convex structure, its construction method can refer to the form of the concave structure, and details will not be elaborated here. At the same time, setting the strengthening structure 1421 as a convex structure is more convenient for handling.

[0133] It needs to be further understood that, such as Figure 6As shown, the top cover body 14 further includes a mounting member 17, and the mounting member 17 is mounted on the recessed structure and is screwed to the first mating structure 1531 of the air guide cover 15.

[0134] Specifically, by arranging the mounting member 17 on the recessed 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, reduce the shaking of the blade 13 caused by poor structural strength during rotation or handling, thereby improving the running stability of the blade 13, and further effectively enhancing the heat exchange effect of the outdoor unit 100 of the HVAC equipment.

[0135] It should be understood that, as Figures 7 to 9 shown, on the side wall of the top plate body, that is, on the side plate 142, a recessed structure is provided, and a mounting hole is provided on the bottom surface of the recessed structure, and the axial direction of the mounting hole 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 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 of 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 is provided on the bottom surface of the recessed 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.

[0136] In some embodiments of the present invention, the number of the reinforcing structures 1421 provided on the top cover body 14 is one, and one reinforcing structure 1421 is arranged along the circumference of the first communication port 143, and one reinforcing 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.

[0137] In some embodiments of the present invention, as Figures 7 to 9 shown, a plurality of reinforcing structures 1421 are provided on the top cover body 14, and all the reinforcing structures 1421 are arranged at intervals along the circumference of the top cover body 14.

[0138] Specifically, in this embodiment, the number of the reinforcing structures 1421 is set to be multiple, so that the reinforcing structures 1421 can be arranged according to the 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 reinforcing structures 1421.

[0139] It should be noted that a plurality of reinforcing structures 1421 are arranged at intervals along the circumferential direction of the top cover body 14, and the circumferential direction of the top cover body 14 is the same as that of the first communication port 143. Among them, the plurality of reinforcing structures 1421 can cover a part of the circumferential direction of the first communication port 143 or can cover the entire circumferential direction of the first communication port 143.

[0140] As Figure 1 shown, a second aspect of the present invention proposes an outdoor unit 100 of a heating and ventilation device. The outdoor unit 100 of the heating and ventilation device includes the top cover assembly 10 and the box body 20 as described above. The top cover assembly 10 is installed and fixed on the top of the box body 20, and at the same time, the top of the box body 20 is in plug-in fit with the top cover body 14 of the top cover assembly 10.

[0141] For the outdoor unit 100 of the heating and ventilation device described in the present invention, when the top cover assembly 10 is used for the outdoor unit 100 of the heating and ventilation device, the blades 13, the mesh cover 11 and the top cover body 14 can be assembled into an integral component and are connected and fixed to the box body 20 of the outdoor unit 100 of the heating and ventilation device. Since the blades 13 are arranged in the receiving space of the top cover body 14 and the blades 13 are arranged at intervals from the first communication port 143, it is possible to effectively reduce the damage to the blades by the external environment before and after the installation of the top cover assembly 10, so that the blades are not squeezed, thereby ensuring the use effect of the blades. In addition, when the top cover assembly 10 is used for the outdoor unit 100 of the heating and ventilation device, the blades 13 are arranged outside the heat exchanger 30 and are not affected by the size of the heat exchanger 30, and the size of the blades 13 can be increased, thereby improving the driving ability of the blades 13 for the air flow and effectively improving the heat exchange effect of the outdoor unit 100 of the heating and ventilation device.

[0142] A third aspect of the present invention further proposes a heating and ventilation device, including the outdoor unit 100 of the heating and ventilation device described in the present invention.
