[0049] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "left", "right", "front", "rear", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" 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 or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0053] See also Figure 1 and Figure 2 The present embodiment provides an air conditioner indoor unit, which includes a base 100, a body 200, a front panel and a fresh air component, the fresh air component includes a rear volute 300 and a front volute 400, and the front volute 400 and the rear volute 300 are buckled together to form a cavity structure.

[0054] The bottom of the rear volute 300 is fixed to the base 100, the bottom of the front volute 400 is detachably connected to the base 100, and the outer edge of the front volute 400 is detachably connected to the outer edge of the rear volute 300; the front panel is detachably connected to the body 200, and the front volute 400 is arranged opposite to the front panel. After the front panel is removed, an open opening will be formed, and the front volute 400 can be removed from the open opening.

[0055] The air conditioner indoor unit provided in this embodiment, when the volute inner cavity and its internal structure need to be repaired or cleaned, first remove the front panel of the air conditioner indoor unit from the body 200 to form an open opening, exposing the front volute 400 of the fresh air component in the body 200; then, the staff can remove the front volute 400 from the open opening, and take the front volute 400 out of the open opening, so that the volute inner cavity is opened, so that the volute inner cavity and its internal structure can be cleaned, and the structure located in the volute inner cavity can also be repaired. In addition, because the front volute 400 and the rear volute 300 are both connected to the base 100, the strength is good, and even if the front panel and the front volute 400 of the air conditioner are removed, the air conditioner indoor unit can maintain sufficient stability and will not shake or fall apart.

[0056] Therefore, when the air-conditioning indoor unit provided in this embodiment needs to be repaired or cleaned, it is only necessary to remove the air-conditioning front panel and the front volute 400 without completely disassembling the air-conditioning. The maintainability is good and the maintenance cost is low.

[0057] Preferably, see Figure 3-Figure 5 The rear volute 300 and the front volute 400 can be fixedly connected by the first threaded connector 500, and the head of the first threaded connector 500 is arranged opposite to the open mouth. When disassembling, the operation can be directly performed from the front side at the open mouth. A screwdriver can be used to unscrew each first threaded connector 500 to realize the detachment of the front volute 400 and the rear volute 300, which is very convenient to operate.

[0058] A plurality of first side ears 310 may be provided at the edge of the rear volute 300, and correspondingly, a plurality of second side ears 410 may be provided at the edge of the front volute 400. The first side ears 310 and the second side ears 410 are provided in one-to-one correspondence, a first through hole is provided on the first side ear 310, and a first threaded hole is provided on the second side ear 410. In this way, the first threaded connector 500 can pass through the first through hole on the first side ear 310 from the front side and be screwed into the first threaded hole on the second side ear 410 to achieve threaded matching.

[0059] It should be noted that the second side ear 410 is arranged on the rear volute 300, that is, the second side ear 410 and the rear volute 300 are an integral structure. On the basis of the fixation of the rear volute 300, the second side ear 410 is also fixed. Therefore, a first threaded hole that cooperates with the first threaded connector 500 is directly opened on the second side ear 410. Compared with the solution of additionally providing a nut, it is easier to operate and does not require manual fixing of the nut, making it more convenient to operate. In addition, the setting of the side ear prevents the first threaded connector from entering the cavity, thereby not affecting the internal cavity, thereby ensuring smooth air outlet.

[0060] The first side ears 310 are dispersedly arranged along the front end edge of the rear volute 300, and correspondingly, the second side ears 410 are dispersedly arranged along the rear end edge of the front volute 400. In this way, the connection parts between the front volute 400 and the rear volute 300 can be dispersed, so that the force applied by the front volute 400 to the rear volute 300 is more evenly distributed, which alleviates the problem of a pair of first side ears 310 and second side ears 410 being damaged due to large force, ensures good structural stability, reduces maintenance frequency, saves maintenance costs, prolongs the service life of the front volute 400 and the rear volute 300, and improves user experience.

[0061] Preferably, the rear surface of the first side ear 310 and the front surface of the second side ear 410 are arranged in contact with each other, so that the rear surface of the first side ear 310 and the front surface of the second side ear 410 can disperse the force and reduce the local pressure, thereby further extending the service life of the first side ear 310 and the second side ear 410.

[0062] In addition, a plurality of columns 110 may be provided on the top of the base 100 , and the columns 110 and the front volute 400 may be fixed in a detachable connection manner, thereby facilitating the fixing and disassembly of the columns 110 and the front volute 400 .

[0063] Specifically, a groove 421 is provided at the bottom of the front volute 400 , the column 110 is inserted into the groove 421 , and the column 110 is connected to the front wall of the groove 421 in a detachable manner.

[0064] Preferably, the column 110 can be fixedly connected to the front groove wall of the groove 421 through the second threaded connector 600. When disassembling, it is only necessary to unscrew each second threaded connector 600 from the front side with a screwdriver to achieve the detachment of the front volute 400 and the base 100, which is very convenient to operate.

[0065] Specifically, a second through hole can be opened on the front side groove wall of the groove 421, and a second threaded hole can be opened on the column 110. In this way, the second threaded connector 600 can pass through the second through hole on the front side groove wall of the groove 421 from the front side and be screwed into the second threaded hole on the column 110 to achieve threaded matching.

[0066] It should be noted that the column 110 is arranged on the base 100, that is, the column 110 and the base 100 are an integral structure. On the basis of the base 100 being fixed, the column 110 is also fixed. Therefore, directly opening a second threaded hole on the column 110 to cooperate with the second threaded connector 600 is more convenient to operate than the solution of additionally providing a nut, and there is no need to manually fix the nut.

[0067] Preferably, see Figure 5 and Figure 6The notch of the groove 421 is set to an L-shaped notch facing the bottom and the rear side, so that when the front volute 400 is pulled out from the front side, the column 110 will not form an obstacle to the front volute 400, and the front volute 400 can be pulled out smoothly.

[0068] A boss 420 may be provided on the outer side of the cavity wall of the front volute 400 so that the groove 421 can be opened on the boss 420 . Thus, the groove 421 will not affect the inner contour of the cavity, thus ensuring smooth air discharge.

[0069] Preferably, the left and right side groove walls of the groove 421 are respectively matched with the left and right side walls of the column 110, so that the column 110 can be used to limit the left and right shaking of the front volute 400. Therefore, when the front volute 400 has a tendency to shake left and right, the column 110 will bear part of the force, thereby dispersing the force at the matching point of the second threaded connector 600 and reducing the local pressure, thereby enhancing the structural stability of the connection between the front volute 400 and the base 100.

[0070] Preferably, see Figure 4 and Figure 5 At least two columns 110 are set, and the columns 110 are arranged at intervals in the left and right directions. In this way, the balance of the front volute 400 can be improved, so that the front volute 400 is not prone to the running tendency of shaking left and right, and the force on the connection between the front volute 400, the rear volute 300 and the base 100 is reduced, so that the connection is not easily damaged.

[0071] Specifically, the bottom surfaces of the rear volute 300 and the front volute 400 are both fitted and pressed against the top surface of the base 100. In this way, the top surface of the base 100 can lift the rear volute 300 and the front volute 400, which not only greatly reduces the stress at each connection between the front volute 400 and the rear volute 300 and the base 100, but also makes the bottom of the rear volute 300 and the front volute 400 more solid and less likely to shake, thereby ensuring the structural stability.

[0072] See also Figure 2 In the specific structure of the fresh air component, a fan blade 700 and a motor 800 are also provided, and the fan blade 700 and the motor 800 are detachably connected to the front volute 400. Therefore, after the front volute 400 is removed, the fan blade 700 and the motor 800 will be removed along with the front volute 400. Compared with removing the fan blade 700 and the motor 800 from the rear volute 300 that is still fixed in the body 200, it is much easier to remove the fan blade 700 and the motor 800 from the front volute 400 that is separated from the body 200. In this way, the disassembly efficiency of the fan blade 700 and the motor 800 can be improved.

[0073] In summary, the embodiment of the present invention discloses an air conditioner indoor unit, which overcomes many technical defects of the conventional air conditioner indoor unit with fresh air function. The air conditioner indoor unit with fresh air function provided by the embodiment of the present invention only needs to remove the front panel and the front volute of the air conditioner when the volute inner cavity and its internal structure need to be repaired or cleaned, without completely disassembling the air conditioner, so the maintainability is good and the maintenance cost is low.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
