Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The invention provides an air conditioner indoor unit and an air conditioner comprising the same.

Referring to fig. 1 to 5, an indoor unit of an air conditioner according to the present invention includes: the cross-flow wind wheel 40, the chassis 10a, the water pan 20 and the wind guide mechanism 30. The chassis 10a is provided with an inner cavity 101 for the cross-flow wind wheel 40 to be installed, and the inner cavity 101 has an opening 101a which extends along the length direction of the cross-flow wind wheel 40 and is used for the cross-flow wind wheel 40 to enter and exit. The water pan 20 is disposed at the opening 101a, and the water pan 20 is detachably connected to the chassis 10 a. The air guide mechanism 30 is connected with the water pan 20, and the air guide mechanism 30 is arranged at the opening 101a and detachably connected with the chassis 10 a.

It will be appreciated that the impeller 40 is removed by translation directly from the opening 101a, rather than by pulling it out from both ends. The inner cavity 101 is defined by the base plate 10a and the heat exchanger 10 b. The water pan 20 and the air guiding mechanism 30 are both detachably connected with the chassis 10a, and the air guiding mechanism 30 is provided with an air duct 31, and the air duct 31 is communicated with the inner cavity 101 so as to allow the airflow generated by the cross-flow wind wheel 40 to flow out.

Specifically, when cleaning the indoor unit of the air conditioner, the water receiving tray 20 and the air guide mechanism 30 need to be detached and cleaned. After the water pan 20 and the air guide mechanism 30 are disassembled, the opening 101a of the inner cavity 101 is free from the structural blockage, and the cross-flow wind wheel 40 can be directly taken out for cleaning. After the cross flow wind wheel 40 is taken out, the inner cavity 101 can be cleaned, and the heat exchanger 10b can be cleaned through the space of the inner cavity 101.

The water pan 20 and the air guiding mechanism 30 may be detachably connected to the bottom plate 101b in various forms, for example: snap connection, threaded connection, riveting, and the like.

According to the technical scheme, an inner cavity 101 is formed in a chassis 10a, and a cross-flow wind wheel 40 is installed; and the inner cavity 101 is provided with an opening 101a, and the cross-flow wind wheel 40 can be directly installed and detached through the opening 101 a. Furthermore, the water pan 20 and the air guiding mechanism 30 are both installed at the opening 101a and are both detachably connected to the chassis 10 a. Therefore, after the water pan 20 and the air guiding mechanism 30 are disassembled, the opening 101a of the inner cavity 101 is opened (i.e. the opening 101a is not shielded by the water pan 20 and the air guiding mechanism 30), and then the cross-flow wind wheel 40 is directly taken out through the opening 101a, so that the operation space for cleaning the indoor unit of the air conditioner is enlarged, and meanwhile, the whole indoor unit of the air conditioner can be cleaned without disassembling the heat exchanger 10 b. Therefore, the disassembly difficulty of the whole air conditioner indoor unit is greatly reduced.

In another embodiment, referring to fig. 3, the water pan 20 and the wind guiding mechanism 30 are detachably connected or integrally formed. In this embodiment, the water pan 20 and the wind guiding mechanism 30 are detachably connected in consideration of the difference of the materials used for the water pan 20 and the wind guiding mechanism 30 and the convenience of disassembling the internal structure of the whole air conditioner internal unit. Of course, the two materials can also be made of the same material, and are integrally formed by an injection molding process during production and manufacturing.

Referring to fig. 3 and 4, the indoor unit of the air conditioner has an air duct front plate 50 spliced with the bottom plate 101b of the inner cavity 101, and the air duct front plate 50 is integrally formed with the water collector 20. Specifically, the air duct front plate 50 is provided to perform a continuous air guiding function mainly in cooperation with the bottom plate 101b of the inner cavity 101. It can be understood that the air flow generated by the cross flow wind wheel 40 is guided by the bottom plate 101b of the inner cavity 101, then flows through the water receiving tray 20, and is guided out of the indoor unit of the air conditioner from the wind guiding mechanism 30. In the process of air flow diversion, if the water pan 20 is not connected with the bottom plate 101b of the inner cavity 101, air flow is shunted through gaps between the components, and all air cannot be led out from the air guide mechanism 30, thereby affecting the whole air guide effect. Therefore, in view of the above situation, the water collector 20 is provided with the air duct front plate 50 for splicing the bottom plate 101b of the inner cavity 101, so that the airflow generated by the cross-flow wind wheel 40 can be guided by the bottom plate 101b of the inner cavity 101 and then continuously guided out of the air guiding mechanism 30 by the air duct front plate 50. Wherein, the air duct front plate 50 can be integrally formed with the water pan 20; or is integrally formed with the inner cavity 101 bottom plate 101b and then is connected with the water pan 20; or a bottom plate 101b separately connected to the drip tray 20 and the inner chamber 101. In this embodiment, the air duct front plate 50 and the water-receiving tray 20 are integrally formed, and when the water-receiving tray 20 is detached, the air duct front plate 50 and the air duct front plate 50 are detached together, so that the air duct front plate 50 can be cleaned conveniently.

In the above embodiment, a supporting plate 501 extends inward from an edge of the duct front plate 50 away from the air guiding mechanism 30, the duct front plate 50 is smoothly connected to the bottom plate 101b of the inner cavity 101, and the supporting plate 501 bears the bottom plate 101b of the inner cavity 101. It will be appreciated that the purpose of providing the pallet 501 is several: firstly, the bottom plate 101b of the inner cavity 101 is used for bearing, and the bottom plate 101b of the inner cavity 101 is prevented from shaking in the air guiding process; secondly, after the supporting plate 501 bears the bottom plate 101b of the inner cavity 101, the air duct front plate 50 can be smoothly connected with the bottom plate 101b of the inner cavity 101; that is to say, at this time, the side edge of the air duct front plate 50 and the side edge of the bottom plate 101b of the inner cavity 101 abut against each other, so that the air duct front plate 50 and the bottom plate 101b of the inner cavity 101 can be effectively prevented from moving relatively in the working process, and a limiting effect is further achieved.

Referring to fig. 3 and 5, in another embodiment, two first end plates 1011 for mounting the cross-flow wind wheel 40 are disposed at two ends of the inner cavity 101, a second end plate 1012 spliced with the two first end plates 1011 is disposed at two ends of the water collector 20, and a mounting hole 1013 for passing a rotating shaft of the cross-flow wind wheel 40 is disposed at a joint of the first end plate 1011 and the second end plate 1012. The second end plate 1012 is detachably connected to the first end plate 1011, for example by a snap connection or a screw connection. Further, since the first end plate 1011 and the second end plate 1012 are formed with the installation hole 1013 after being spliced, it can be understood that the installation hole 1013 may be provided in a gap of the first end plate 1011, and the gap is covered after the second end plate 1012 is spliced with the first end plate 1011. Or the two end plates are provided with half holes respectively to be formed in a matched mode. In this embodiment, the first end plate 1011 and the second end plate 1012 are symmetrically disposed in a semi-circular shape, and the installation hole 1013 is formed at the center when the two end plates are assembled. The installation hole 1013 is used for providing a through-hole for installing the rotating shaft of the wind turbine 40 to work with other structures. It should be noted that, one end of the cross flow wind wheel 40 has a shaft, and the other end has a shaft hole for installing the motor shaft. The rotating shaft of the cross flow wind wheel 40 refers to a shaft lever or a motor shaft at both ends thereof.

In another embodiment, referring to fig. 1 and 6, a motor cavity 102 for mounting the wind turbine motor 60 and a motor cover 103 for covering the motor cavity 102 are disposed on the chassis 10a, an opening 101a of the motor cavity 102 faces the water collector 20, and the motor cover 103 is detachably connected to the chassis 10 a. Specifically, the motor cover 103 is detachably attached to the chassis 10a to cover the motor chamber 102. Wherein, the motor shaft of the wind wheel motor 60 passes through the installation hole 1013 and is connected with the cross flow wind wheel 40 to drive the cross flow wind wheel 40 to rotate. Furthermore, the opening 101a of the motor cavity 102 faces the water collector 20, and it can be understood that when the wind turbine motor 60 is detached for cleaning, after the motor cover 103 is opened (the opening 101a of the motor cavity 102 is opened), since the opening 101a of the motor cavity 102 faces the water collector 20, the wind turbine motor 60 can be directly taken out for cleaning or replacement and maintenance without being blocked by the electric control box 10c, the heat exchanger 10b and other structures. It should be noted that the opening 101a of the motor cavity 102 faces the water pan 20, and the opening direction is only understood as an opposite direction, that is, as long as the wind turbine motor 60 can be directly taken out from the opening 101a of the motor cavity 102 without being blocked by any component when the motor cover 103 is detached. For example, the opening 101a of the motor cavity 102 may be disposed toward the air guiding mechanism 30, or between the water receiving tray 20 and the air guiding mechanism 30.

In another preferred embodiment, referring to fig. 6 to 8, the indoor unit of an air conditioner further includes a bearing seat 80, a clamping table 701 is disposed on a surface of the bearing seat 80, and a clamping groove 702 adapted to the clamping table 701 is disposed on the chassis 10 a.

It can be understood that the rotating shaft (not the motor shaft) of the cross flow wind wheel 40 is connected to a bearing 80 after passing through the installation hole 1013, and the bearing 80 is assembled on the bearing seat 80. The bearing seat 80 is directly clamped with the clamping groove 702 arranged on the chassis 10a through the clamping table 701, so that the connecting step of the bearing seat 80 and the chassis 10a is simplified, and the disassembling difficulty of the bearing seat 80 is greatly reduced.

In another preferred embodiment, referring to fig. 9 to 15, the indoor unit of the air conditioner has a casing 90, the casing 90 includes a middle frame 901 and a front cover 902, the middle frame 901 is connected to the chassis 10a, and the front cover 902 is detachably connected to the middle frame 901. In the process of cleaning the indoor unit of the air conditioner, the whole shell 90 is usually detached to clean the internal structure, so that the detachment step is complex and the time is long. In this embodiment, the front cover 902 and the middle frame 901 are detachably connected, so that when the indoor unit of the air conditioner is to be cleaned, the internal components can be further detached and cleaned by detaching the front cover 902, thereby further simplifying the detachment step and reducing the detachment difficulty.

When the air conditioner indoor unit is cleaned, first, the front cover 902 is removed to expose the internal components (the water receiving tray 20, the air guide mechanism 30, the base plate 10a, and the like) of the air conditioner indoor unit. Next, the water receiving tray 20 and the air guide mechanism 30 are detached from the chassis 10a, and the cross flow wind wheel 40, the bearing housing 80, the motor cover 103, and the like are further exposed. Subsequently, the bearing seat 80, the motor cover 103 and the wind wheel motor 60 are removed, and then the cross flow wind wheel 40 is directly taken out of the inner cavity 101. After the cross flow wind wheel 40 is removed, the heat exchanger 10b and the like can be cleaned through the space provided in the inner cavity 101. Finally, after cleaning, all the parts are installed back again in the reverse order. Therefore, the disassembly steps of the indoor unit of the air conditioner are greatly simplified.

On the basis of the above embodiments, the present embodiment provides a specific implementation manner in which the middle frame 901 and the front cover 902 are detachable. One surface of the middle frame 901 facing the chassis 10a is convexly provided with a first clamping table 903, one end of the front cover 902 far away from the chassis 10a is provided with a fixing buckle 904 corresponding to the first clamping table 903 in position, the fixing buckle 904 comprises an elastic part 904a extending towards the middle frame 901, a second clamping table 904b is arranged on the elastic part 904a, the middle frame 901 and the front cover 902 are buckled with the second clamping table 904b through the first clamping table 903, and one end of the front cover 902 close to the chassis 10a is limited and installed on the middle frame 901. Specifically, when the front cover 902 is installed, one end close to the chassis 10a is limited and installed on the middle frame 901, and then a pressure is applied to one end of the front cover 902 far from the chassis 10 a. Accordingly, the elastic portion 904a of the fixing buckle 904 is elastically deformed under pressure, so that the second clamping platform 904b can be buckled with the first clamping platform 903, thereby completing the buckling of the whole front cover 902 to the middle frame 901. Similarly, when detaching, a force opposite to the aforementioned force is applied to separate the second clamping platform 904b from the first clamping platform 903.

Different from the previous embodiment, this embodiment provides another specific way of detachably connecting the middle frame 901 with the front frame 902. A clasp 905 is arranged at one end of the front cover 902 close to the chassis 10a, a buckle hole 906 corresponding to the clasp 905 is arranged on the middle frame 901, the clasp 905 is inserted into the buckle hole 906 to limit the front cover 902 to be installed on the middle frame 901, and one end of the front cover 902 far from the chassis 10a is limited to be installed on the middle frame 901. Specifically, the end of the front cover 902 far from the chassis 10a is limited and mounted on the middle frame 901, and the end close to the chassis 10a is directly fastened to the fastening hole 906 on the middle frame 901 through a fastening hook 905, so that the connection mode between the front cover 902 and the middle frame 901 is greatly simplified, and the mounting and dismounting of the front cover 902 and the middle frame 901 are facilitated.

In order to make the middle frame 901 and the front cover 902 more stably fit, in this embodiment, the middle frame 901 has two side plates along the length direction thereof, an abutting strip 907 abutting against the front cover 902 is convexly disposed on the inner side of one end of the side plates facing the front cover 902, a limit opening 907a is disposed on the abutting strip 907, and a limit portion 908 inserted into the limit opening 907a is disposed on the front cover 902. It can be understood that the abutting strips 907 are cut off at the middle part in the length direction, and one end of one abutting strip 907 at the separated part is bent towards the inside of the air conditioner indoor unit, so that an angle difference exists between the abutting strip 907 and the other abutting strip 907 to form a limiting opening 907a for the limiting part 908 arranged on the front cover 902 to be inserted into to limit the front cover 902.

Furthermore, the position-limiting portion 908 elastically abuts against the abutting strip 907 corresponding to the periphery of the position-limiting opening 907 a. It is understood that the abutting strip 907 corresponding to the periphery of the limiting opening 907a is the aforementioned one portion of the abutting strip 907 with the bending arrangement. Wherein, the two elastic contact can be understood as: the position-limiting part 908 is elastically abutted against the abutting strip 907; alternatively, the abutting strip 907 is provided with elasticity to elastically abut against the limiting part 908; furthermore, the position-limiting portion 908 and the abutting bar 907 are both elastic to perform elastic abutting.

In the present embodiment, the abutment strip 907 is provided with elasticity. When the limit part 908 is inserted into the limit opening 907a, the limit part 908 presses the abutting strip 907 to elastically deform, and after the limit part 908 and the abutting strip 907 are matched, the abutting strip 907 is given a abdication position by the limit part 908, so that the abutting strip 907 recovers the original shape to abut against the limit part 908 for abutting.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
