For example, a product or device including a series of components does not necessarily have to be limited to all the clearly listed components, but may include other components not clearly listed or inherent to these products or devices.

[0060] The air conditioner indoor unit provided by the implementation manners of the present application can have various implementation forms. The air conditioner indoor unit can be an air conditioner indoor unit with a fresh air function.

[0061] Such asFigure 1 As shown in the figure, an indoor air conditioner provided by the present application includes a housing 100, and the housing 100 is used to form the overall appearance of the indoor air conditioner; the housing 100 has a top and a bottom, the top of the housing 100 and the bottom of the housing 100 are opposite sides, and the direction from the top of the housing 100 to the bottom of the housing 100 is the height direction of the housing 100; the right side of the housing 100 and the left side of the housing 100 are opposite ends, and the direction from the left side of the housing 100 to the right side of the housing 100 is the length direction of the housing 100; the front side of the housing 100 and the rear side of the housing 100 are opposite sides, and the direction from the front side of the housing 100 to the rear side of the housing 100 is the thickness direction of the housing 100.

[0062] In practical applications, the housing 100 is usually arranged at the top of the room or in the upper space of the room. Among them, the rear side of the housing 100 faces the wall, and the front side of the housing 100 faces the user.

[0063] As Figure 1 and Figure 2 shown, the housing 100 includes a housing air inlet 101. The housing air inlet 101 is arranged at the top of the housing 100, and indoor air enters the interior of the housing 100 through the housing air inlet 101; the housing air inlet 101 extends along the length direction of the housing 100 to increase the air intake of the indoor air conditioner.

[0064] As Figures 3 - 6 shown, the housing 100 includes a housing air outlet 102. The housing air outlet 102 is opened on the front side of the housing 100 and is arranged close to the bottom of the housing 100, that is, the housing air outlet 102 is located at the front lower side of the housing 100; the air inside the housing 100 is output to the room through the housing air outlet 102; the housing air outlet 102 extends along the length direction of the housing 100 to increase the air output of the indoor air conditioner.

[0065] As Figures 3 - 6 shown, the housing 100 includes a fresh air outlet 103, and outdoor air is output to the room through the fresh air outlet 103. In practical applications, the fresh air outlet 103 can be opened at the top of the housing 100, or can be opened on the front side of the housing 100, or can be opened at positions such as the front bottom of the housing 100.

[0066] In the present application, the fresh air outlet 103 is opened at the bottom of the front side of the housing 100. The fresh air outlet 103 and the housing air outlet 102 are arranged along the length direction of the housing 100, and the fresh air outlet 103 is arranged close to the right side of the housing 100.

[0067] As Figure 1 and Figure 2As shown, the air conditioner indoor unit includes a wind deflector 200. The wind deflector 200 is rotatably arranged at the air outlet 102 of the casing, and is used to open or close the air outlet 102 of the casing; the rotation axis of the wind deflector 200 is arranged along the length direction of the casing 100; by adjusting the rotation angle of the wind deflector 200, the air flow output from the air outlet 102 of the casing can also be guided.

[0068] The air conditioner indoor unit is defined to form a heat exchange air duct, and the air inlet 101 of the casing and the air outlet 102 of the casing are respectively communicated with the heat exchange air duct.

[0069] As Figure 2 shown, the air conditioner indoor unit includes a heat exchanger 300. The heat exchanger 300 is located in the heat exchange air duct. The air in the heat exchange air duct contacts the heat exchanger 300 and is heat-exchanged by the heat exchanger 300 to form air-conditioning air. The air-conditioning air is output from the air outlet 102 of the casing to the room to meet the cooling or heating needs of users.

[0070] The heat exchanger 300 is arranged close to the air inlet 101 of the casing so that the heat exchanger 300 can heat-exchange the air entering the heat exchange air duct in time.

[0071] It should be noted that the air-conditioning air can be cold air, hot air, or even normal temperature air.

[0072] As Figure 2 shown, the air conditioner indoor unit includes a heat exchange fan 400. The heat exchange fan 400 is located in the heat exchange air duct. The heat exchange fan 400 is located on the leeward side of the heat exchanger 300, and the axis of the heat exchange fan 400 extends along the length direction of the casing 100.

[0073] By operating the heat exchange fan 400, the indoor air is introduced into the heat exchange air duct from the air inlet 101 of the casing. After being heat-exchanged by the heat exchanger 300 to form air-conditioning air, the air-conditioning air flows from the air outlet 102 of the casing to the room.

[0074] It should be noted that in the wall-mounted air conditioner indoor unit, the heat exchange fan 400 is usually a cross-flow fan.

[0075] The air conditioner indoor unit includes a fresh air component for introducing outdoor fresh air; the fresh air component is installed on the casing 100.

[0076] The fresh air component includes a fresh air casing. The fresh air casing is defined to form a fresh air duct. The fresh air outlet 103 is communicated with the fresh air duct. The fresh air duct is communicated with the outside, so that outdoor air can enter the fresh air duct and then be output to the room from the fresh air outlet 103; the fresh air duct and the heat exchange air duct are arranged along the length direction of the casing 100; the fresh air duct and the heat exchange air duct are independently arranged.

[0077] The fresh air component includes a fresh air fan. The fresh air fan is arranged in the fresh air duct and installed in the fresh air housing. By the operation of the fresh air fan, outdoor air is introduced into the fresh air duct from the outside, and then output to the room through the fresh air outlet 103.

[0078] It should be noted that the fresh air fan is usually a centrifugal fan.

[0079] Such as Figure 3 and Figure 4 As shown, the air conditioner indoor unit includes a decorative lamp component 500. The decorative lamp component 500 is arranged close to the fresh air outlet 103 and is used to indicate the position of the fresh air outlet 103 and whether the air conditioner indoor unit starts the fresh air function, etc.

[0080] Since the size of the fresh air outlet 103 is relatively small compared to the housing air outlet 102, the position of the fresh air outlet 103 is relatively concealed and not easy to be seen. Moreover, the wind speed during fresh air outlet is small and not easy to be felt by the human body. By arranging the decorative lamp component 500 at a position close to the fresh air outlet 103 and using the decorative lamp component 500 to emit light, the visualization of fresh air is realized. For example, when the air conditioner indoor unit starts the fresh air function, the decorative lamp component 500 emits light, which can not only facilitate the user to observe the position of the fresh air outlet 103, but also convey the information that the air conditioner indoor unit starts the fresh air function to the user.

[0081] The decorative lamp component 500 is arranged inside the housing 100. On the one hand, it can ensure the aesthetics of the air conditioner indoor unit, and on the other hand, it can protect the decorative lamp component 500.

[0082] In this application, the fresh air outlet 103 is arranged at the bottom of the front side of the housing 100. The decorative lamp component 500 can be located at the outer edge above the fresh air outlet 103 or at the outer edge below the fresh air outlet 103.

[0083] Such as Figure 9 、 Figure 11 and Figure 12 As shown, the decorative lamp component 500 includes a decorative lamp 530. The decorative lamp 530 is used to emit light, and the light of the decorative lamp 530 propagates through the front side of the housing 100.

[0084] Such as Figures 9 - 13 As shown, the decorative lamp component 500 includes a display box 510. The display box 510 is used to install the decorative lamp 530; the display box 510 is installed on the housing 100. By installing the decorative lamp 530 in the display box 510 and fixing the display box 510, the installation and fixation of the decorative lamp 530 are realized, which can reduce the damage to the decorative lamp 530 during the installation process and also facilitate the installation of the decorative lamp 530.

[0085] The display box 510 is provided with a passing portion for the light of the decorative lamp 530 to pass through. After the decorative lamp 530 is installed on the display box 510, the light emitted by the decorative lamp 530 passes through the passing portion for propagation, so as to prevent the display box 510 from blocking the light.

[0086] It should be noted that the decorative lamp 530 is usually also connected with a circuit board, wires, etc. When the decorative lamp 530 is installed on the display box 510, at least some of the electrical components or circuit elements connected to the decorative lamp 530 are also installed on the display box 510. This is common knowledge in the art and will not be elaborated here.

[0087] In some embodiments, a cavity is defined inside the display box 510, and the decorative lamp 530 is disposed in the cavity. One side of the display box 510 facing the outer cover 130 is provided with a cavity opening, so that the light emitted by the decorative lamp 530 disposed in the cavity can pass through the cavity opening for propagation.

[0088] As Figure 2 shown, the housing 100 includes a base 120, and the heat exchanger 300, the heat exchange fan 400 and the fresh air housing are respectively installed on the base 120, and the heat exchange fan 400, the heat exchanger 300 and the fresh air housing are respectively arranged along the length direction of the housing 100.

[0089] As Figures 3 - 6 shown, the housing 100 includes an outer cover 130. An outer cover cavity with an opening facing the rear side of the housing 100 is defined inside the outer cover 130. The base 120 is disposed at the opening of the outer cover cavity, and the outer cover 130 covers the base 120. The outer cover 130 and the base 120 jointly define a heat exchange air duct.

[0090] It should be noted that the housing air inlet 101 is opened at the top of the outer cover 130. In this application, the fresh air outlet 103 is opened at the bottom of the front side of the outer cover 130.

[0091] The front bottom of the base 120 is provided with a base opening, and the front bottom of the outer cover 130 is provided with an outer cover opening. The base opening and the outer cover opening are correspondingly arranged to jointly define a housing air outlet 102.

[0092] As Figure 2 shown, the housing 100 includes a front panel 110. The front panel 110 is disposed on the front side of the outer cover 130, and the front panel 110 is used to cover the outer cover 130 to ensure the aesthetics of the air conditioner indoor unit. It should be noted that the outer cover 130 is usually in a mesh structure, and the user can remove the front panel 110 to repair the components inside the housing 100.

[0093] The display box 510 is disposed within the outer cover cavity and is mounted on the outer cover 130; one side of the display box 510 where the through portion is provided is in contact with the inner wall of the front side of the outer cover 130, so as to reduce the distance between the decorative lamp 530 and the front panel 110, and avoid the situation that the light emitted by the decorative lamp 530 cannot be projected onto the front panel 110 or the projection effect of the light emitted by the decorative lamp 530 onto the front panel 110 is reduced due to the excessive distance between the decorative lamp 530 and the front panel 110.

[0094] As Figure 10 shown, a first mating surface 511 is defined on one side of the display box 510 where the through portion is provided, and the first mating surface 511 is correspondingly arranged and cooperates with the inner wall of the front side of the outer cover 130.

[0095] As Figure 7 shown, a second mating surface 132 is defined on the inner wall of the outer cover 130, and the second mating surface 132 is correspondingly arranged and cooperates with the first mating surface 511.

[0096] If the shape adaptability between the first mating surface 511 and the second mating surface 132 is relatively low, when the first mating surface 511 and the second mating surface 132 are in contact with each other, there will be at least partial large mating gaps between at least part of the first mating surface 511 and at least part of the second mating surface 132. On the one hand, the mating gaps may cause light leakage of the decorative lamp 530 and reduce the penetration of the decorative lamp 530. On the other hand, it may reduce the firmness of the connection between the display box 510 and the outer cover 130, and water vapor may contact the decorative lamp 530 through the mating gaps and the through portion, affecting the normal operation of the decorative lamp 530. Therefore, the first mating surface 511 usually makes full contact with the second mating surface 132 to reduce the mating gaps between the two.

[0097] Since the side of the outer cover 130 opposite to the outer cover opening is usually a curved surface with a curvature, correspondingly, the second mating surface 132 is usually a curved surface with a curvature. The first mating surface 511 usually needs to be designed as a curved surface with a curvature adapted to the second mating surface 132 to ensure the adaptability between the first mating surface 511 and the second mating surface 132, so that the first mating surface 511 can make full contact with the second mating surface 132. This will increase the production difficulty of the display box 510, and the curved surface shapes of the outer covers 130 in different specifications of air conditioner indoor units are different, which also makes the display box 510 can only be installed on a specific outer cover 130, reducing the versatility of the display box 510.

[0098] Based on this, in the present application, a flexible member 520 is provided between the first mating surface 511 and the second mating surface 132, such that the first mating surface 511 and the second mating surface 132 are in contact with each other through the flexible member 520, so that the flexible member 520 can fill and block the mating gap, preventing the curved surface shape of the first mating surface 511 from being unable to adapt to the curved surface shape of the second mating surface 132.

[0099] Specifically, the flexible member 520 is disposed on the first mating surface 511 and can be compressed and deformed. When the display box 510 is installed in the outer cover 130, at least a part of the flexible member 520 is compressed and deformed, so that the first mating surface 511 is in full contact with the second mating surface 132 through the flexible member 520, thereby enabling the display box 510 to be adapted to outer covers 130 of different specifications and increasing the versatility of the display box 510.

[0100] The flexible member 520 can fill and block the mating gap, and can also prevent water vapor from coming into contact with the decorative lamp 530 through the mating gap, increasing the reliability of the operation of the decorative lamp 530, and can also increase the firmness of the connection between the display box 510 and the outer cover 130.

[0101] In some embodiments, the flexible member 520 is a compressible and deformable component such as foam.

[0102] In some embodiments, the flexible member 520 is adhered to the first mating surface 511 with glue.

[0103] In different air conditioner indoor units, the thickness of the flexible member 520 is not fixed. The thickness of the flexible member 520 is selected according to the size of the mating gap. Selecting the thickness of the flexible member 520 according to the mating gap belongs to the well-known common sense technology in the art and will not be elaborated herein.

[0104] Since the front panel 110 is provided on the front side of the outer cover 130, in order to reduce the blocking effect of the outer cover 130 on light, an avoidance portion 131 is provided on the front side wall of the outer cover 130. The avoidance portion 131 is arranged corresponding to the through portion, so that the light of the decorative lamp 530 can pass through the avoidance portion 131 and be projected onto the front panel 110 and transmitted through the front panel 110.

[0105] It should be noted that a logo can be engraved at the position of the front panel 110 corresponding to the avoidance portion 131. When the light is projected onto the front panel 110, the logo can be displayed, increasing the aesthetics or indicating the manufacturer of the air conditioner indoor unit, etc. The method of engraving the logo on the front panel 110 belongs to the conventional technical means in the art and will not be elaborated herein.

[0106] It should also be noted that the front panel 110 is usually a plastic part. When the thickness of the front panel 110 is within a certain range, light can pass through the front panel 110 for display. This belongs to the well-known common sense technology in the art and will not be elaborated herein.

[0107] In some embodiments, the avoidance portion 131 is provided at the opening of the outer cover 130; the second mating surface 132 is provided at the outer edge of the avoidance portion 131.
