[0002] Currently, ordinary air conditioners can only circulate indoor air. Over time, the quality of indoor air deteriorates, affecting the user experience. In response, wall-mounted air conditioners with fresh air intake systems are becoming increasingly popular among consumers, as they offer this function.

[0003] The fresh air module of a wall-mounted fresh air unit has an air inlet chamber and a centrifugal chamber. Due to the influence of the molding process of the internal structure of the fresh air housing (such as the air guide ring), the fresh air housing is currently mainly composed of three parts. For example, Chinese patent (publication number CN113137664A) discloses a scheme in which a fresh air housing is composed of a sealing cover, a volute, and a volute cover. In this scheme, the sealing cover and the volute cover are combined to form the air inlet chamber, and the volute and the volute cover are combined to form the centrifugal chamber. This results in the current fresh air housing having more components, which increases the difficulty of processing and assembly. Summary of the Invention

It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0047] This application provides a fresh air housing and an air conditioner, which will be described in detail below.

[0048] First, refer to Figure 1 , Figure 2 as well as Figure 3 , Figure 1 This paper shows an assembly diagram of a fresh air housing according to an embodiment of the present application. Figure 2 This illustration shows a schematic diagram of a disassembled structure of the fresh air bottom shell 10 and the first volute 20 in an embodiment of this application. Figure 3 The diagram shows a split structure of the fresh air base shell 10, the first volute 20, and the second volute 30 in an embodiment of this application, wherein the fresh air shell portion is integrally formed with the air conditioner base 100.

[0049] This application reduces the number of fresh air housing parts that actually need to be manufactured and processed by integrally molding a portion of the fresh air housing on the air conditioner base 100, thereby reducing the processing and assembly difficulty of the fresh air housing and helping to reduce the manufacturing cost of the air conditioner.

[0050] As an exemplary embodiment where the fresh air housing is integrally formed with the air conditioner base 100, please refer to... Figure 1 , Figure 2 as well as Figure 3 The fresh air housing includes:

[0051] Fresh air base shell 10, fresh air base shell 10 is integrally formed with air conditioner base 100;

[0052] The first volute 20 is connected to the fresh air bottom shell 10 along the first direction to form an air inlet chamber 110;

[0053] The second volute 30 is connected to the fresh air bottom shell 10 and / or the first volute 20 along the second direction to form a centrifugal chamber 120.

[0054] The first direction has at least a directional component perpendicular to the second direction.

[0055] Specifically, the air conditioner base 100 serves as the mounting base for the air conditioner, and can accommodate some components of the air conditioner, such as the evaporator, impeller, and fan. The air conditioner base 100 includes a fresh air intake shell 10, which is integrally formed with the air conditioner base 100; for example, the fresh air intake shell 10 is formed simultaneously with the air conditioner base 100 during manufacturing. As an example, such as... Figure 1 As shown, the air conditioner base 100 can be the mounting base of the wall-mounted air conditioner indoor unit. The fresh air base 10 can be located at the left or right end of the air conditioner base 100, thereby allowing the air conditioner base 100 to have more installation space to install the fan wheel and evaporator of the wall-mounted air conditioner indoor unit.

[0056] Understandably, the air conditioner base 100 can also be a part of other types of air conditioners, such as the rear panel or chassis of a cabinet air conditioner; or the fresh air base shell 10 can also be located in the middle of the air conditioner base 100.

[0057] The first volute 20 is used to dock with the fresh air bottom shell 10 to form the air intake chamber 110, such as Figure 2 As shown, the first volute 20 can dock with the fresh air base 10 along a first direction. As an example, the first volute 20 can dock with the fresh air base 10 along a length direction perpendicular to the air conditioner base 100. It is understood that the first volute 20 can also dock with the fresh air base 10 along a direction perpendicular to the width or height of the air conditioner base 100.

[0058] The second volute 30 is used to dock with the fresh air bottom shell 10 and / or the first volute 20 to form a centrifugal chamber 120, such as Figure 3 As shown, the second volute 30 can dock with the fresh air base shell 10 and / or the first volute 20 along the length of the fresh air base shell 10. It is understood that the second volute 30 can also dock with the fresh air base shell 10 and / or the first volute 20 in other directions, ensuring that the first direction has at least a component perpendicular to the second direction, so that the fresh air base shell 10 can form a cavity that docks with the first volute 20 and the second volute 30 during demolding.

[0059] Generally, to increase the volume of the centrifugal chamber 120 to improve the air delivery efficiency of the air conditioner's fresh air module, refer to... Figure 3The second volute 30 simultaneously connects to the sides of both the fresh air bottom shell 10 and the first volute 20, meaning that the sides of the fresh air bottom shell 10 and the first volute 20 serve as part of the inner wall surface of the centrifuge chamber 120. Together with the second volute 30, this forms a centrifuge chamber 120 with a larger volume. It is understandable that the second volute 30 can also connect independently to either the fresh air bottom shell 10 or the first volute 20 to form the centrifuge chamber 120; for example, the second volute 30 can connect independently to the side of the first volute 20 to enclose and form the centrifuge chamber 120.

[0060] Since the first volute 20 connects with the fresh air base shell 10 along the first direction to form the air inlet chamber 110, and the second volute 30 connects with the fresh air base shell 10 and / or the first volute 20 along the second direction to form the centrifugal chamber 120, when manufacturing the fresh air base shell 10 and the first volute 20, they can be demolded along the first direction, thus forming the internal spaces of the fresh air base shell 10 and the first volute 20 corresponding to the centrifugal chamber 120 respectively. When manufacturing the second volute 30, demolding along the second direction forms a portion of the space corresponding to the centrifugal chamber 120.

[0061] This application provides an integrated fresh air base shell 10 on the air conditioner base 100, and a first volute 20 is connected to the fresh air base shell 10 along a first direction to form an air inlet chamber 110. A second volute 30 is connected to the fresh air base shell 10 and / or the first volute 20 along a second direction to form a centrifugal chamber 120. Since the fresh air base shell 10 can be molded in one go during the processing of the air conditioner base 100, the actual number of fresh air shell parts that need to be manufactured and processed is reduced to two, thereby reducing the processing difficulty and assembly difficulty of the fresh air shell.

[0062] In some embodiments of this application, in order to reduce the air resistance as air flows from the air inlet chamber 110 into the centrifuge chamber 120, see [reference needed]. Figure 1 And 4, Figure 4 The diagram shows a structural schematic of a fresh air bottom shell 10 and a first volute 20 docking in an embodiment of this application. The fresh air bottom shell 10 has a first flow guide ring 11 and the first volute 20 has a second flow guide ring 21. The first flow guide ring 11 and the second flow guide ring 21 are docked along a first direction to form an annular flow guide ring 50. The sum of the central angles of the corresponding circles of the first flow guide ring 11 and the second flow guide ring 21 is greater than or equal to 360°.

[0063] When the first volute 20 is connected to the fresh air bottom shell 10, the first guide ring 11 and the second guide ring 21 are connected to form the entire guide ring 50. When air flows from the air inlet chamber 110 into the centrifugal chamber 120, the guide ring with a smaller inner diameter can guide the air to the axis of the centrifugal chamber 120. The air is then thrown to the inner wall of the centrifugal chamber 120 by the rotation of the centrifugal impeller, thereby accelerating the air flow rate and ultimately reducing the wind loss of air flowing from the air inlet chamber 110 into the centrifugal chamber 120.

[0064] Generally, the central angles of the first guide ring 11 and the second guide ring 21 can each be 180° to form a 360° annular guide ring 50. Understandably, the central angles of the first guide ring 11 and the second guide ring 21 can each be greater than 180° to allow for the provision of a connecting sealing structure at the edges of the first guide ring 11 and the second guide ring 21, such as a sealing step at the edges of the first guide ring 11 and the second guide ring 21.

[0065] Furthermore, to facilitate the docking of the fresh air bottom shell 10, the first volute 20, and the second volute 30 to form the air inlet chamber 110 and the centrifugal chamber 120, see [reference needed]. Figure 2 as well as Figure 5 , Figure 5 The diagram shows a structural schematic of a fresh air bottom shell 10 in an embodiment of this application. The fresh air bottom shell 10 has a first docking groove 111 and a first docking sub-groove 112 on opposite sides of the first flow guide ring 11. The first volute 20 has a second docking groove 211 and a second docking sub-groove 212 on opposite sides of the second flow guide ring 21. The second volute 30 has a third docking groove 311 on the side facing the first volute 20. The first docking groove 111 and the second docking groove 211 are combined to form an air inlet chamber 110. The first docking sub-groove 112 docks with the second docking groove 212 and is combined with the third docking groove 311 to form a centrifugal chamber 120.

[0066] In the above embodiments, the first docking groove 111 of the fresh air bottom shell 10 and the second docking groove 211 of the first volute 20 can be formed by demolding along the first direction during processing, while the first docking sub-groove 112 of the fresh air bottom shell 10, the second docking sub-groove 212 of the first volute 20, and the third docking groove 311 of the second volute 30 can be formed by demolding along the second direction during processing, so that the first docking groove 111 and the second docking groove 211 can be combined along the first direction to form the air inlet chamber 110, while the third docking groove 311, the first docking sub-groove 112, and the second docking sub-groove 212 can be combined along the second direction to form the centrifugal chamber 120, and finally form a fresh air shell separated by the first guide ring 11 and the second guide ring 21.

[0067] As an example only, the first docking groove 111 and the second docking groove 211 can be square grooves or circular grooves, respectively. The first docking sub-groove 112 and the second docking sub-groove 212 can be semi-circular grooves, and the third docking groove 311 can be a circular groove, so that the first docking sub-groove 112 and the second docking sub-groove 212 can be combined to form a circular docking groove. After the circular docking groove is docked with the third docking groove 311, a centrifuge chamber is finally formed.

[0068] In some embodiments of this application, such as an embodiment where the fresh air base shell 10 has a first guide ring 11 and the first volute 20 has a second guide ring 21, see the following reference. Figure 2 The air inlet chamber 110 is also equipped with a filter screen adjacent to the first guide ring 11 and the second guide ring 21. The filter screen covers the channel formed by the first guide ring 11 and the second guide ring 21. When air enters the air inlet chamber 110, it is purified and filtered by the filter screen and then accelerated by the centrifugal chamber 120 before being blown into the room.

[0069] Furthermore, to facilitate the installation and removal of the filter, the first volute 20 is provided with an opening 40 for the filter to enter and exit; and / or the fresh air base shell 10 is provided with an opening 40 for the filter to enter and exit. As an example, see [reference needed]. Figure 2 An opening 40 for the filter screen to enter and exit can be provided in the first housing. When the filter screen is installed, it is inserted into the air inlet chamber 110 through the opening 40. Conversely, when the filter screen is disassembled, it can be taken out through the opening 40. Generally, in order to facilitate the fixing of the filter screen, the fresh air bottom housing 10 can be provided with a filter screen fixing structure, such as a slot, to improve the stability of the filter screen installation.

[0070] It is understandable that an opening 40 can be set separately at the fresh air bottom shell 10, and a filter fixing structure can be set inside the first volute 20; or an opening 40 can be set at the same time in the fresh air bottom shell 10 and the second volute 30. When the first volute 20 is connected to the fresh air bottom shell 10, the openings 40 of the fresh air bottom shell 10 and the second volute 30 together form a channel for the filter to enter and exit.

[0071] In some embodiments of this application, to facilitate air intake and exhaust from the fresh air housing, the fresh air housing also has an air inlet 12 and an air outlet 22. As an example, see [reference needed]. Figure 2 The fresh air bottom shell 10 is provided with an air inlet 12 that communicates with the air inlet chamber 110, and the first volute 20 is provided with an air outlet 22 that communicates with the centrifugal chamber 120. Outside air enters the air inlet chamber 110 through the air inlet 12, then flows into the centrifugal chamber 120, and finally is discharged into the room through the air outlet 22.

[0072] It is worth noting that the above-mentioned air inlet 12 and air outlet 22 are only examples. The fresh air inlet and air outlet 22 can also have a variety of configurations. For example, the first volute 20 can be provided with an air inlet 12 communicating with the air inlet chamber 110, and the fresh air bottom shell 10 can be provided with an air outlet 22 communicating with the centrifugal chamber 120. Another example is that the fresh air bottom shell 10 can be provided with an air inlet 12 communicating with the centrifugal chamber 120, and the second volute 30 can be provided with an air outlet 22.

[0073] For easier connection of the fresh air base shell 10, the first volute 20, and the second volute 30, please refer to [link / reference needed]. Figure 6 , Figure 6 A partial structural diagram of the docking of the fresh air bottom shell 10 and the first volute 20 in an embodiment of this application is shown. The fresh air bottom shell 10 has a first pair of interfaces 13 facing a first direction and a first docking notch 14 facing a second direction. The first volute 20 has a second pair of interfaces 23 docking with the first pair of interfaces 13 and a second docking notch 24 combined with the first docking notch 14. The second volute 30 has a third pair of interfaces 31 docking with the first docking notch 14 and the second docking notch 24.

[0074] In the above embodiment, the first pair of interfaces 13 and the second pair of interfaces 23 are connected along the first direction. After the first docking notch 14 and the second docking notch 24 are set in the setting direction to form a complete interface, the complete interface is connected with the third pair of interfaces 31, thereby realizing the purpose of docking between the fresh air housing, the first volute 20 and the second volute 30.

[0075] Furthermore, to ensure the airtightness of the connection between the fresh air base shell 10, the first volute 20, and the second volute 30, please refer to [further details omitted]. Figure 6 The fresh air base shell 10 has a first slot 15 at the edge of the first pair of interfaces 13, and the first volute 20 has a first insert 25 that mates with the first slot 15 at the edge of the second pair of interfaces 23; the fresh air base shell 10 has a first sub-slot 16 at the edge of the first docking notch 14, the first volute 20 has a second sub-slot 26 at the edge of the second docking notch 24, and the second volute 30 has a second insert 32 that mates with the first sub-slot 16 and the second sub-slot 26 at the edge of the third pair of interfaces 31.

[0076] In the above embodiment, the first slot 15 cooperates with the first insert block 25 to realize the docking of the fresh air bottom shell 10 and the first volute 20, while ensuring the sealing of the edges of the first pair of interfaces 13 and the second pair of interfaces 23. After the fresh air bottom shell 10 docks with the first volute 20, the first sub-slot 16 and the second sub-slot 26 combine to form a complete slot. After the second volute 30 docks with the fresh air bottom shell 10 and the first volute 20, the second slot cooperates with both the first sub-slot 16 and the second sub-slot 26, thereby ensuring the sealing of the docking edges of the third pair of interfaces 31 with the first docking notch 14 and the second docking notch 24.

[0077] Furthermore, to ensure the stability of the connection between the fresh air base shell 10, the first volute 20, and the second volute 30, please refer to section 3 and... Figure 6The fresh air base shell 10 has a first threaded connecting post 17 arranged along a first direction and a second threaded connecting post 18 arranged along a second direction. The first volute 20 is provided with a first connecting hole 27 corresponding to the first threaded connecting post 17, and the second volute 30 is provided with a second connecting hole 33 corresponding to the second threaded connecting post 18. When the first volute 20 is connected to the fresh air base shell 10, the screw passes through the first connecting hole 27 and engages with the threaded hole on the first threaded connecting post 17. When the second volute 30 is connected to both the first volute 20 and the fresh air base shell 10, the screw passes through the second connecting hole 33 and engages with the threaded hole on the second threaded connecting post 18, thus achieving the connection between the fresh air base shell 10, the first volute 20, and the second volute 30.

[0078] It is understandable that the fresh air base shell 10, the first volute 20, and the second volute 30 can be connected in other ways or have other types of connection structures. For example, the fresh air base shell 10, the first volute 20, and the second volute 30 can be connected by welding or adhesive bonding. Alternatively, the fresh air base shell 10, the first volute 20, and the second volute 30 can also be connected by buckles and slots.

[0079] It is worth noting that the above description of the fresh air housing is only for clearly illustrating the verification process of this application. Under the guidance of this application, those skilled in the art can make equivalent modifications to the above-mentioned fresh air housing. For example, the second volute 30 can be connected to the fresh air bottom shell 10 first, and then the first volute 20 can be connected to form the fresh air housing.

[0080] Furthermore, to better implement the fresh air housing in the embodiments of this application, an air conditioner is also provided based on the fresh air housing. The air conditioner includes the fresh air housing as described in any of the above embodiments. Because the air conditioner in the embodiments of this application is equipped with the fresh air housing described above, it possesses all the beneficial effects of the aforementioned fresh air housing, which will not be elaborated further here.
