Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically provides an air duct component and an air conditioner indoor unit. Background Art

[0002] The indoor heat exchanger of an air conditioner's indoor unit is connected to an inlet pipe and an outlet pipe. The inlet pipe is used to flow refrigerant into the indoor heat exchanger, while the outlet pipe is used to flow refrigerant out of the indoor heat exchanger. Because the inlet and outlet pipes are prone to deformation and displacement, they need to be fixed to prevent vibration, thereby improving the stability and safety of the pipes and preventing any impact on the refrigerant flow efficiency.

[0003] In the prior art, a pipe pressing plate is usually used to press the inlet pipe and the outlet pipe onto the air duct component of the indoor unit. However, the number of parts is large, which makes disassembly and assembly inconvenient and is prone to missing parts.

[0004] Accordingly, the art requires a new air duct assembly and air conditioner indoor unit to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the above technical problem, that is, to solve the problem in the prior art that the structure of the inlet pipe and the outlet pipe of the indoor heat exchanger is inconvenient to disassemble and assemble and is easy to miss.

[0006] In a first aspect, the utility model provides an air duct assembly, which includes: a heat exchanger bracket, which is used to install a heat exchanger; an air duct component, which is used to constitute an air duct, and the air duct component and the heat exchanger bracket are arranged to form an accommodating space to constrain part of the inlet pipe and / or outlet pipe of the heat exchanger within the accommodating space.

[0007] When the above technical solution is adopted, the inlet pipe and / or outlet pipe are fixed by constraining part of the inlet pipe and / or outlet pipe within the accommodating space enclosed by the air duct component and the heat exchanger bracket. There is no need to set up a separate pipe pressure plate, which reduces the number of parts, facilitates disassembly and assembly, and avoids the problem of missing installation.

[0008] In a specific embodiment of the above-mentioned air duct assembly, a first accommodating groove is provided on the heat exchanger bracket, and the first accommodating groove and the air duct component are surrounded to form the accommodating space.

[0009] When adopting the above technical solution, since the inlet pipe and / or outlet pipe are close to the heat exchanger, the inlet pipe and / or outlet pipe are constrained in the first receiving groove on the heat exchanger bracket, which can ensure that the inlet pipe and / or outlet pipe are constrained at a position close to the heat exchanger, thereby improving the stability of the inlet pipe and / or outlet pipe.

[0010] In a specific embodiment of the above-mentioned air duct assembly, a second accommodating groove is provided on the air duct component, and the second accommodating groove and the first accommodating groove are surrounded to form the accommodating space.

[0011] When the above technical solution is adopted, the first accommodating groove and the second accommodating groove are jointly enclosed to form an accommodating space, which can improve the restraint effect on the inlet pipe and / or outlet pipe, and the size of the first accommodating groove and the second accommodating groove can also be adjusted according to the requirements of the size of the accommodating space.

[0014] In a specific embodiment of the above-mentioned air duct assembly, a reinforcing rib is provided on a side of the press-fit structure facing away from the inlet pipe and / or the outlet pipe.

[0015] When adopting the above technical solution, since the press-fitting structure presses the inlet pipe and / or outlet pipe tightly and constrains it within the accommodating space, the press-fitting structure needs to withstand the reaction force of the inlet pipe and / or outlet pipe. Therefore, the strength of the press-fitting structure can be increased by setting reinforcing ribs to avoid deformation or damage of the press-fitting structure.

[0016] In a specific embodiment of the above-mentioned air duct assembly, the air duct component further includes a connecting structure, the press-fit structure is connected to the air duct structure via the connecting structure, and a water collecting trough is provided on the top of the connecting structure.

[0017] When the above technical solution is adopted, the condensed water on the heat exchanger and the air duct structure can fall downward into the water collecting tank, so that the air duct component also has the water collecting function, further optimizing the structure.

[0018] In a specific embodiment of the above-mentioned air duct assembly, a drainage hole is provided on the bottom wall of the water collecting tank.

[0019] When the above technical solution is adopted, the water in the water collecting tank can be discharged out of the water collecting tank through the drainage hole.

[0024] In a second aspect, the present invention further provides an air-conditioning indoor unit, wherein the air-conditioning indoor unit includes the air duct assembly, and the heat exchanger is an indoor heat exchanger.

[0025] When the above technical solution is adopted, the air conditioner indoor unit does not need to be equipped with a separate pipe pressure plate, which reduces the number of parts, facilitates disassembly and assembly, and avoids the problem of missing installation.

[0026] Compared with the prior art, the beneficial effect of the air duct assembly provided by the present invention is that by constraining part of the inlet pipe and / or outlet pipe within the accommodating space enclosed by the air duct component and the heat exchanger bracket, the inlet pipe and / or outlet pipe are fixed, and there is no need to set up a separate pipe pressure plate, which reduces the number of parts, facilitates disassembly and assembly, and avoids the problem of missing installation.

In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0036] Based on the problems pointed out in the background technology that the structure of fixing the inlet pipe and outlet pipe of the indoor heat exchanger in the prior art is inconvenient to disassemble and assemble and is prone to missing installation, the invention aims to fix the inlet pipe and / or outlet pipe by constraining part of the inlet pipe and / or outlet pipe within the accommodating space enclosed by the air duct component and the heat exchanger bracket, without the need to set up a separate pipe pressure plate, reducing the number of parts, facilitating disassembly and assembly, and avoiding the problem of missing installation.

[0037] See first Figure 1 , Figure 1 The figure shows the overall structure of the air duct assembly of the present invention. Figure 1As shown, the air conditioner indoor unit of the present invention includes an air duct assembly and an indoor heat exchanger 1. The air duct assembly forms an air duct, and the indoor heat exchanger 1 is mounted on the air duct assembly. The indoor heat exchanger 1 includes a core, a first header pipe 2, and a second header pipe 3. The core can be connected to the first header pipe 2 via multiple first branch pipes and to the second header pipe 3 via multiple second branch pipes. When the indoor heat exchanger 1 is used as an evaporator, the inlet pipe is the first header pipe 2 and the outlet pipe is the second header pipe 3. When the indoor heat exchanger 1 is used as a condenser, the inlet pipe is the second header pipe 3 and the outlet pipe is the first header pipe 2. The refrigerant flows into the core through the inlet pipe and flows out of the core through the outlet pipe. The first header pipe 2 and the second header pipe 3 are typically covered with a protective cover. Optionally, the air conditioner indoor unit can be a vertical air conditioner indoor unit, a wall-mounted air conditioner indoor unit, a window air conditioner indoor unit, etc.

[0038] It will be understood by those skilled in the art that although the above Figure 1 It is described that the inlet pipe is the first main pipe 2 or the second main pipe 3, and the outlet pipe is another main pipe, but this is not restrictive. The inlet pipe can also be the first branch pipe or the second branch pipe, and the outlet pipe can be another branch pipe. As long as the refrigerant can flow into the core through the inlet pipe and flow out of the core through the outlet pipe, technical personnel in this field can make adjustments as needed.

[0039] See below Figure 1 and Figure 2 , Figure 2 The bottom view of the air duct assembly of the present invention is shown. Figure 1 and Figure 2 As shown, the air duct assembly includes a heat exchanger bracket 4 and an air duct component 5. The heat exchanger bracket 4 is used to mount the heat exchanger and is provided with a first receiving groove 41. The air duct component 5 includes an air duct structure 51, a press-fit structure 52, and a connecting structure 53. The air duct structure 51 constitutes the air duct. The press-fit structure 52 is provided with a second receiving groove 521. The second receiving groove 521 and the first receiving groove 41 enclose a receiving space. Parts of the first and second manifolds 2 and 3 are disposed within the receiving space, and the first and second manifolds 2 and 3 are constrained within the receiving space by the squeezing action of the receiving space on the protective sleeve. The press-fit structure 52 is connected to the air duct structure 51 via the connecting structure 53. By constraining parts of the first and second manifolds 2 and 3 within the receiving space enclosed by the air duct component 5 and the heat exchanger bracket 4, the first and second manifolds 2 and 3 are fixed. This eliminates the need for a separate tube clamp, reduces the number of parts, facilitates assembly and disassembly, and avoids the problem of missing components.

[0040] See below Figure 1-Figure 3 , Figure 3 Shows Figure 1 The enlarged structure of part A. Figure 1-Figure 3As shown, the side of the press-fitting structure 52 on which the second accommodating groove 521 is provided is the first side, and the side of the press-fitting structure 52 opposite to the first side is the second side. The second side is provided with a reinforcing rib 522. Since the press-fitting structure 52 presses the inlet pipe and the outlet pipe tightly and constrains them in the accommodating space, the press-fitting structure 52 needs to withstand the reaction force of the inlet pipe and the outlet pipe. Therefore, the setting of the reinforcing rib 522 can increase the strength of the press-fitting structure 52 and prevent the press-fitting structure 52 from being deformed or damaged.

[0041] A water collecting trough 531 is provided on the top of the connecting structure 53, and a drainage hole is provided on the bottom wall of the water collecting trough 531. The condensed water on the heat exchanger and the air duct structure 51 can fall downward into the water collecting trough 531, so that the air duct component 5 has a water collecting function, further optimizing the structure. The water in the water collecting trough 531 is discharged to the outside of the water collecting trough 531 through the drainage hole.

[0042] The heat exchanger bracket 4 is provided with a positioning post 42, and the press-fit structure 52 is provided with a positioning hole 523. The positioning post 42 is inserted into the positioning hole 523. The arrangement of the positioning post 42 and the positioning hole 523 facilitates the positioning of the press-fit structure 52, and also facilitates the installation of the air duct component 5. Optionally, the positioning hole 523 is arranged around the second accommodating groove 521 on the press-fit structure 52 to ensure that the second accommodating groove 521 and the first accommodating groove 41 can be better aligned to form an accommodating space. In addition, the top of the air duct structure 51 can also be provided with a positioning hole 523. Correspondingly, the top of the heat exchanger bracket 4 is also provided with a positioning post 42. The arrangement of the positioning post 42 and the positioning hole 523 also facilitates the positioning of the air duct structure 51, and further facilitates the installation of the air duct component 5. Possibly, a plurality of reinforcing ribs are provided on the positioning post 42 to increase the strength of the positioning post 42.

[0043] The heat exchanger bracket 4 is connected to the press-fit structure 52 via fasteners. A first mounting hole is provided on the heat exchanger bracket 4, and a second mounting hole 524 is provided on the press-fit structure 52. Bolts pass through the first and second mounting holes 524 to secure the heat exchanger bracket 4 to the press-fit structure 52. Optionally, at least two second mounting holes 524 are provided around the second accommodating slot 521 to enhance the connection strength between the press-fit structure 52 and the heat exchanger bracket 4 and ensure that the first and second manifolds 2 and 3 are confined within the accommodating space. Furthermore, the air duct structure 51 may also be provided with second mounting holes 524 to secure the heat exchanger bracket 4 to the air duct structure 51. The heat exchanger bracket 4 and the air duct structure 51 may also be connected via a snap-fit structure.

[0044] During assembly, first install the indoor heat exchanger 1 on the heat exchanger bracket 4, place the first main pipe 2 and the second main pipe 3 in the first accommodating groove 41, and then install the air duct component 5. When installing the air duct component 5, first align the positioning holes 523 on the air duct structure 51 and the positioning holes 523 on the press-fit structure 52 with the positioning columns 42 on the heat exchanger bracket 4, and then install the air duct structure 51 and the press-fit structure 52 to the heat exchanger bracket 4 respectively through fasteners.

[0045] Optionally, the press-fit structure 52, the connection structure 53, and the air duct structure 51 are integrally formed, which can simplify the manufacturing process and use a set of molds, and can also facilitate assembly and disassembly.

[0046] Those skilled in the art will appreciate that, although it is described above that the first accommodating groove 41 and the second accommodating groove 521 are jointly arranged to form an accommodating space, and parts of the first main pipe 2 and the second main pipe 3 are constrained within the accommodating space, this is not restrictive, and the second accommodating groove 521 may not be provided on the air duct component 5, and the first side surface of the air duct component 5 and the first accommodating groove 41 may be arranged to form an accommodating space, as long as parts of the inlet pipe and the outlet pipe can be constrained within the accommodating space; only one of the first main pipe 2 and the second main pipe 3 may be constrained within the accommodating space; those skilled in the art may make adjustments as needed, without departing from the principles of the present invention and within the scope of protection of the present invention.

[0047] In addition, although it is described above that the top of the connection structure 53 is provided with a water collecting tank 531, this is not restrictive. The connection structure 53 may not be provided with a water collecting tank 531, and those skilled in the art may make adjustments as needed.

[0048] It should be noted that the duct assembly can be applied to the indoor unit of the air conditioner or to the outdoor unit of the air conditioner. Accordingly, when the duct assembly is applied to the indoor unit of the air conditioner, the heat exchanger is the indoor heat exchanger 1, and when the duct assembly is applied to the outdoor unit of the air conditioner, the heat exchanger is the outdoor heat exchanger.

[0049] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned embodiments so that the present invention can be applied to more specific application scenarios.

[0050] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
