DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] An embodiment of the present application provides a HVAC device, which may include an air-conditioning outdoor unit and an air-conditioning indoor unit. The air-conditioning outdoor unit is usually installed outside the target space, and the air-conditioning indoor unit is usually installed inside the target space, and the air-conditioning indoor unit and the air-conditioning outdoor unit may form a circulating flow path to achieve joint cooperation. For example, the air-conditioning indoor unit and the air-conditioning outdoor unit may be connected via a refrigerant pipeline to achieve the functions of the HVAC equipment in cooling, heating, dehumidifying and purifying the air on the target space, thereby achieving a comfortable target space, wherein the air-conditioning outdoor unit of the HVAC device may be one, and the air-conditioning indoor unit may be multiple.

[0032] The air conditioner indoor unit is described in detail below.

[0033] See also Figure 1-Figure 2In some embodiments, the air conditioner indoor unit 1 includes a shell 10, a heat exchanger 20, a wind wheel assembly 30 and a supporting structure 40, wherein an air duct 10a is arranged inside the shell 10, and the shell 10 may include a casing 11 and a volute 12, the casing 11 and the volute 12 are detachably connected, the volute 12 is arranged in the air duct 10a, and the heat exchanger 20 is arranged in the air duct 10a. The heat exchanger 20 is a device that transfers part of the heat of the hot fluid to the cold fluid, and the heat exchanger 20 can be divided into a fixed tube plate heat exchanger, a U-shaped tube plate heat exchanger, and a plate heat exchanger according to the structural form. The embodiment of the present application does not specifically limit the structural form of the heat exchanger 20.

[0034] The wind wheel assembly 30 is arranged in the air duct 10a, and the wind wheel assembly 30 and the heat exchanger 20 are arranged at intervals in the airflow direction of the air duct 10a. The wind wheel assembly 30 includes at least two wind wheels 31. The embodiment of the present application does not specifically limit the number of wind wheel assemblies 30. For example, the number of wind wheel assemblies 30 can be two or four. The embodiment of the present application is described below with the number of wind wheel assemblies 30 being two.

[0035] See also Figure 1-Figure 4 The support structure 40 is arranged between adjacent wind wheels 31, and includes a support seat 41 and a connecting component 42. The connecting component 42 is installed on the support seat 41 and is used to connect the rotating shaft of the adjacent wind wheel 31 (not shown in the figure). The support seat 41 is connected to the shell 10, and the support seat 41 abuts against the heat exchanger 20.

[0036] Specifically, the wind wheel assembly 30 plays a role in promoting air flow transmission in the air duct 10a, the heat exchanger 20 plays a role in heat exchange, the support structure 40 is arranged between the two wind wheels 31, and the rotating shafts of the two wind wheels 31 are connected by the connecting assembly 42 to increase the length of the wind wheel assembly 30, that is, the connecting assembly 42 may include a bearing 421 and a bearing seat 422, each wind wheel 31 has a rotating shaft of the wind wheel 31 extending outward, and the connection between the two wind wheels 31 can connect the rotating shafts of the two wind wheels 31 through the bearing 421, and the bearing seat 422 has a bearing hole ( The bearing 421 is installed in the bearing hole, wherein the bearing 421 can be a rolling bearing, which can be divided into an outer ring, an inner ring and a ball disposed between the outer ring and the inner ring, the outer ring is interference fitted with the bearing hole, the rotating shaft of the wind wheel 31 is installed on the inner ring, and the air-conditioning indoor unit 1 also includes a motor 50, which is also disposed in the air duct 10a and connected to the wind wheel assembly 30. When the motor 50 is started, the wind wheel assembly 30 can be moved, and the rotational movement between the two wind wheels 31 can be realized through the rolling bearing, thereby improving the convenience of assembling the wind wheel assembly 30.

[0037] Furthermore, the connecting assembly 42 can be installed on the support base 41, that is, the support base 41 is provided with an installation space 41a (see Figure 6 The connecting assembly 42 is installed in the installation space 41a, and there is no gap between the connecting assembly 42 and the installation space 41a, so as to ensure the smooth transmission of the wind wheel assembly 30, and the outer portion of the support seat 41 has a groove 41d (see Figure 6 As shown), the ends of the two opposite wind wheels 31 can be installed in the groove 41d to support the two wind wheels 31, and the support seat 41 is in contact with the heat exchanger 20. It can be understood that the support structure 40 can connect the two wind wheels 31 to meet the air volume requirements of the HVAC equipment while improving the convenience of assembling the wind wheel assembly 30, and the support seat 41 is arranged between the two wind wheels 31 to support the two wind wheels 31 to avoid deformation due to the long length of the two wind wheels 31. In this way, the stability of the operation of the wind wheel assembly 30 is ensured. The support structure 40 can also support the heat exchanger 20. It can be understood that since the size of the heat exchanger 20 needs to match the size of the air duct 10a, at this time, the size of the heat exchanger 20 is relatively large. The heat exchanger 20 is large, and is supported by the support seat 41, so that the heat exchanger 20 can be prevented from being deformed due to excessive span and stress concentration in the middle position due to factors such as vibration. At the same time, when the support seat 41 supports the heat exchanger 20, the support seat 41 can realize the limited fixation of the heat exchanger 20, and the heat exchanger 20 can reversely realize the supporting effect of the support seat 41. At this time, the heat exchanger 20 bears the weight of the connecting component 42. In this way, the position of the volute 12 corresponding to the support structure 40 can share the load-bearing of the connecting component 42 because of the support of the heat exchanger 20, so that the thin-walled volute 12 has the effect of not being easily deformed. That is, the support structure 40 realizes two-way support, and the support seat 41 interacts with the heat exchanger 20.

[0038] The embodiment of the present application sets a support structure 40 between adjacent wind wheels 31. The support structure 40 includes a support seat 41 and a connecting assembly 42. The support seat 41 can be used to support the ends of two opposite wind wheels 31 to ensure the smooth operation of the wind wheel assembly 30. At the same time, the connecting assembly 42 connects the rotating shafts of adjacent wind wheels to achieve the connection between two adjacent wind wheels 31. In this way, the convenience of assembling the wind wheel assembly 30 is improved. At the same time, the support seat 41 can also support the heat exchanger 20. In this way, the heat exchanger 20 can be prevented from being deformed due to excessive span and stress concentration in the middle due to factors such as vibration.

[0039] In some embodiments, the support structure 40 also includes a buffer member, which is connected to the support seat 41 and abuts against the heat exchanger 20. It can be understood that the buffer member is arranged between the support seat 41 and the heat exchanger 20. Since the support seat 41 can be used to support the heat exchanger 20, the support seat 41 adopts a material with a certain hardness to facilitate supporting the heat exchanger 20. If the support seat 41 is in direct contact and abutment with the heat exchanger 20, during the operation of the HVAC equipment, due to the vibration of the wind wheel assembly 30, the support seat 41 can transfer the vibration of the wind wheel assembly 30 to the heat exchanger 20, so that the HVAC equipment generates a large noise when working. Therefore, a buffer member can be set at the abutment between the support seat 41 and the heat exchanger 20, so that the heat exchanger 20 contacts the buffer member to reduce the large noise generated by the HVAC equipment when working.

[0040] Furthermore, in some other embodiments, the buffer member may be a sponge. It is understandable that one side of the sponge is connected to the support seat 41, and the other side of the sponge abuts against the heat exchanger 20. When the heat exchanger 20 abuts against the support seat 41, since the support seat 41 is made of a material with a certain hardness, a sponge is arranged between the support seat 41 and the heat exchanger 20 to prevent the support seat 41 from directly contacting the heat exchanger 20. In this way, the sponge plays a buffering role for the support seat 41 to support the heat exchanger 20. Moreover, since the sponge is a porous material with good water absorption, when the HVAC system is in cooling mode or dehumidification mode, the heat exchanger 20 is an evaporator. At this time, condensation water will be generated on the surface of the evaporator. The sponge can absorb the condensation water to prevent excessive condensation water from flowing into the volute 12 to cause damage to the motor. The sponge can absorb a certain amount of condensation water. In this way, more condensation water can be avoided in the volute 12, thereby ensuring the normal operation of the HVAC equipment.

[0041] See also Figure 4 In some embodiments, the outer side of the support seat 41 facing the heat exchanger 20 is formed with a support surface 411 adapted to the outer surface contour of the heat exchanger 20, and the buffer is installed on the support surface 411, that is, the support surface 411 is installed with a buffer on the side close to the heat exchanger 20. The embodiment of the present application does not specifically limit the installation form of the buffer, for example, the buffer is bonded to the support surface 411, and the embodiment of the present application does not specifically limit the shape of the support surface 411. For example, the support surface 411 can be rectangular or square. The support surface 411 is adapted to the outer surface contour of the heat exchanger 20. When the support surface 411 abuts against the heat exchanger 20 through the buffer, because the support surface 411 is adapted to the outer surface contour of the heat exchanger 20, the support surface 411 can better support the heat exchanger 20, and can prevent the heat exchanger 20 from being deformed due to stress concentration caused by factors such as vibration in the middle position, thereby improving the support effect of the support structure 40 on the heat exchanger 20.

[0042] See also Figure 5-Figure 7 In some embodiments, the support base 41 includes a first support member 412 and a second support member 413 .

[0043] The first support member 412 is connected to the shell 10, that is, the first support member 412 can be detachably connected to the shell 10, and can also be non-detachably connected to the shell 10. The embodiment of the present application does not specifically limit the connection method between the first support member 412 and the shell 10. When the first support member 412 is detachably connected to the shell 10, the first support member 412 and the shell 10 can be connected by bonding, screws, etc.

[0044] The second support member 413 can be detachably connected to the first support member 412, can be detachably connected to the shell 10, or can be detachably connected to both the first support member 412 and the shell 10. The embodiment of the present application does not make specific requirements for this, and designers can design it according to actual conditions. The second support member 413 cooperates with the first support member 412 to form an installation space 41a for installing the connecting component 42, and the outer wall surface of the second support member 413 abuts against the heat exchanger 20.

[0045] Specifically, the first support member 412 has a first mounting slot hole 412a, the second support member 413 has a second mounting slot hole 413a, and the connecting component 42 also includes a bearing seat 422, a portion of the bearing seat 422 is installed in the first mounting slot hole 412a, and another portion of the bearing seat 422 is installed in the second mounting slot hole 413a, thereby realizing the installation of the first support member 412 and the second support member 413 and the connecting component 42. In this way, the installation and disassembly of the support structure 40 are simple, and the outer wall surface of the second support member 413 abuts against the heat exchanger 20, that is, the outer wall surface of the second support member 413 is formed with a supporting surface 411 on the side close to the heat exchanger 20, and a buffer member is installed on the supporting surface 411, and the buffer member abuts against the heat exchanger 20, thereby realizing the support of the heat exchanger 20 by the second support member 413.

[0046] See also Figure 4 as well as Figure 7 In some embodiments, the air conditioner indoor unit 1 further includes a water receiving tray 60 located in the air duct 10a, the water receiving tray 60 is disposed below the heat exchanger 20, and the water receiving tray 60 is provided with a fixing portion 61, and the fixing portion 61, the first connecting portion 4132 and the first supporting member 412 are fixed together by screws.

[0047] Specifically, the water receiving tray 60 can be used to collect and discharge moisture in the air, and the water receiving tray 60 is arranged below the heat exchanger 20. When the HVAC equipment is working, the moisture in the air will be sucked into the heat exchanger 20. Under the action of the refrigerant, the heat exchanger 20 condenses the moisture in the air into water droplets, and flows into the water receiving tray 60 through the drainage hole. The design of the water receiving tray 60 allows the water droplets to flow out of the air-conditioning indoor unit 1 to ensure the dryness of the air-conditioning indoor unit 1.

[0048] Furthermore, the water receiving tray 60 is provided with a fixing portion 61, and the fixing portion 61 can be arranged on a side away from the heat exchanger 20, so that the fixing portion 61, the first connecting portion 4132 and the first supporting member 412 are fixed together by screws, that is, the fixing portion 61, the first connecting portion 4132 and the first supporting member 412 share the same slot hole, and the fixing portion 61, the first connecting portion 4132 and the first supporting member 412 are connected together by screws, thereby saving the preparation cost of the HVAC equipment.

[0049] Please continue reading Figure 4 as well as Figure 7 Since the first mounting slot 412a is nested in a part of the bearing seat 422, the second support member 413 is detachably connected to the first support member 412. Therefore, when the wind wheel assembly 30 needs to be repaired or replaced, the water tray 60 can be removed first, and then the second support member 413 can be pulled out, so as to realize the removal of the second support member 413 and the first support member 412, and the sponge on the support surface 411 can form a buffer space with the heat exchanger 20, so the wind wheel assembly 30 can be repaired or replaced without disassembling the heat exchanger 20, so that the disassembly of the wind wheel assembly 30 is convenient.

[0050] In some embodiments, based on the fact that the first support member 412 and the second support member 413 are detachably connected, the connection between the first support member 412 and the second support member 413 has an interface (not shown in the figure), and the bearing seat 422 can have an axis line (not shown in the figure) along the horizontal direction CC of the air-conditioning indoor unit 1. When projected along the cross-sectional plane AA, the interface may pass through the axis line or may not pass through the axis line. The embodiment of the present application does not specifically limit whether the interface passes through the axis line.

[0051] Exemplarily, when the interface passes through the axis line, the first mounting slot 412a on the first support member 412 and the second mounting slot 413a on the second support member 413 are evenly installed with the bearing seat 422, so that the first support member 412 and the second support member 413 can be easily removed from the bearing 422 seat.

[0052] Exemplarily, when the interface does not pass through the axis, at this time, the first mounting slot 412a on the first support member 412 and the second mounting slot 413a on the second support member 413 are not evenly mounted with the bearing seat 422, that is, the depth of the first mounting slot 412a is greater than the depth of the second mounting slot 413a, or the depth of the second mounting slot 413a is greater than the depth of the first mounting slot 412a. The embodiment of the present application does not specifically limit this. For example, when the depth of the second mounting slot 413a is greater than the depth of the first mounting slot When the depth of the mounting slot 412a is large, the portion of the support seat 41 wrapped by the second mounting slot 413a is larger than the portion of the support seat 41 wrapped by the first mounting slot 412a, and the first mounting slot 412a and the second mounting slot 413a are installed seamlessly with the bearing seat 422. When the second support member 413 needs to be disassembled, a technician needs to manually shake them to disassemble the second support member 413 and the bearing seat 422. In this way, the stability of the installation of the second support member 413 and the bearing seat 422 is improved.

[0053] It should be noted that when the interface does not pass through the axial centerline, the distance from the interface to the axial centerline is no more than 0.5 times the maximum diameter of the bearing seat 422, so that the bearing seat 422 can be installed in the first mounting slot 412a or the second mounting slot 413a. If the distance from the interface to the axial centerline is greater than 0.5 times the maximum diameter of the bearing seat 422, when the bearing seat 422 is installed in the first mounting slot 412a or the second mounting slot 413a, it is easy to be blocked by the outer wall of the first support member 412 or the second support member 413, which makes it difficult to install the bearing seat 422 in the first mounting slot 412a or the second mounting slot 413a.

[0054] See also Figure 7 In some embodiments, the first support member 412 and the shell 10 are an integral structure, that is, the first support member 412 is non-detachably connected to the shell 10, wherein the shell 10 may include a volute 12, the volute 12 is arranged in the air duct 10a and is non-detachably connected to the first support member 412, and the volute 12 can be used to increase the airflow speed of the wind wheel assembly 30, wherein the volute 12 and the first support member 412 are integrally formed, so that the volute 12 does not need to be connected to the first support member 412 by screws, which is convenient for technicians to install the first support member 412 and the volute 12. In this way, not only the convenience of installation of HVAC equipment is improved, but also the material preparation cost of HVAC equipment is saved.

[0055] See also Figure 7-Figure 8In some embodiments, the second support member 413 includes a support body 4131, a first connection portion 4132 and a second connection portion 4133, wherein the first connection portion 4132 is connected to the support body 4131 and is detachably connected to the first support member 412, and the second connection portion 4133 is connected to the support body 4131 and is detachably connected to the first support member 412, that is, the first connection portion 4132 and the second connection portion 4133 are both detachably connected to the first support member 412, for example, the first connection portion 4132 and the second connection portion 4133 can be connected to the first support member 412 by screwing.

[0056] Please continue reading Figure 7-Figure 8 Further, in some embodiments, the first connection portion 4132 is connected to the side of the support body 4131 away from the heat exchanger 20, and the first connection portion 4132 is detachably connected to the first support member 412, and the second connection portion 4133 is connected to the side of the support body 4131 facing the heat exchanger 20 and is clamped with the first support member 412. It can be understood that the first connection portion 4132 and the second connection portion 4133 are both connected to the first support member 412, and the first connection portion 4132 is detachably connected to the first support member 412, and the second connection portion 4133 is clamped with the first support member 412, that is, the second support member 413 and the first support member 412 have two connection forms, thereby improving the stability of the connection between the second support member 413 and the first support member 412.

[0058] Specifically, the wind wheel assembly 30 can be arranged near the air outlet so that the airflow formed by the wind wheel assembly 30 flows into the room through the air outlet, wherein the first connecting portion 4132 and the first support member 412 are detachably connected, that is, the connection form between the first connecting portion 4132 and the first support member 412 can be a threaded connection or a clamping connection. When the connection form between the first connecting portion 4132 and the first support member 412 is a threaded connection, the technician can disassemble the panel. Since the projection of the first connecting portion 4132 toward the bottom falls within the area of ​​the air outlet, the technician can observe the screws threadedly connecting the first connecting portion 4132 and the first support member 412 after disassembling the panel. In this way, it is convenient to disassemble the second support member 413 from the wind wheel assembly 30.

[0059] See also Figure 7-Figure 8Furthermore, in some embodiments, the second connection portion 4133 is one of the hook 41b and the slot 41c provided on the support body 4131, and the first support member 412 is provided with the other of the hook 41b and the slot 41c, that is, when the second connection portion 4133 is the hook 41b, the first support member 412 is provided with the slot 41c adapted to the hook 41b of the second connection portion 4133, and when the first support member 412 is provided with the hook 41b, the second connection portion 4133 is provided with the slot 41c adapted to the hook 41b of the first support member 412, and the virtual line in the direction in which the hook 41b is detached from the slot hole of the slot 41c passes through the air outlet.

[0060] Exemplarily, when the second connecting portion 4133 is a hook 41b and the first support member 412 is provided with a slot 41c that is compatible with the hook 41b of the second connecting portion 4133, on the basis of disassembling the first connecting portion 4132 and the first support member 412, since the connection form between the second connecting portion 4133 and the first support member 412 is snap-fit, and the virtual line in the direction in which the hook 41b is detached from the slot hole of the slot 41c passes through the air outlet, that is, when the second support member 413 and the first support member 412 are disassembled, the second support member 413 can be detached from the first support member 412 along the direction of the air outlet, thereby facilitating the disassembly of the second support member 413 and the first support member 412.

[0061] At the same time, since the second support member 413 is separated from the first support member 412 along the direction of the air outlet, it can be understood that the second support member 413 is separated from the first support member 412 along the direction of the air outlet on the side away from the heat exchanger 20. When the wind wheel assembly 30 needs to be repaired or replaced, since the disassembly direction of the second support member 413 is away from the heat exchanger 20, and the outer wall surface of the second support member 413 is in contact with the heat exchanger 20, the wind wheel assembly 30 can be repaired or replaced without disassembling the heat exchanger 20. In this way, the efficiency of the assembly of the wind wheel assembly 30 is improved.
