[0034] The present invention provides an indoor unit of an air conditioner.

[0035] In at least one embodiment of the present invention, as shown in Figs. 1 to 4, the air conditioner indoor unit 100 includes: a housing 1 which includes a face frame 11 and a panel 12. The panel 12 is provided with a first fresh air opening 121, and the face frame 11 is provided with a second fresh air opening 111 corresponding to the first fresh air opening 121; a fresh air assembly 2 installed in the housing 1, and the air passage of the fresh air assembly 2 is communicated with the second fresh air opening 111, and a sealing component 3 arranged at the second fresh air opening 111, and is configured to seal a gap between the sealing surface frame 11 and the fresh air assembly 2 and / or a gap between the sealing surface frame 11 and the panel 12.

[0036] In the present embodiment, the indoor unit of an air conditioner 100 may be a stand unit, a ceiling unit, a wall-mounted indoor unit, or the like. The housing 1 can provide a basic space for installation and a supporting structure for the indoor unit 100 of an air conditioner. The housing 1 may also include an air guiding plate, a chassis, etc. The face frame 11 can provide basic installation and support for the components installed therein, and takes typically a frame structure. The specific structure can refer to the design in the market. The panel 12 is usually installed on the front side of the face frame 11 to maintain the overall consistency of the indoor unit 100. The panel 12 can be detachably installed on the face frame 11 or movably connected to the face frame 11. The specific structure is not limited herein, and an appropriate design can be selected according to practical requirements. The first fresh air opening 121 provided on the panel 12 may be an opening or may be of a plurality of small holes.

[0037] The fresh air assembly 2 is typically installed in the housing 1, and can introduce outdoor air into the room through the air passage, and then enter the room after passing through the second fresh air opening 111 and the first fresh air opening 121 in sequence to provide continuous and fresh air for the closed indoor space, thereby increasing the oxygen content of the indoor air and eliminating air conditioner sickness. The fresh air assembly 2 is generally provided with a cover 22 to form an air passage inside. The sealing component 3 can seal the gap between the cover 22 and the face frame 11. The sealing component 3 may be consist of one or more of sealants, rubber sealing components, silica-gel sealing components, etc. The sealing component 3 can be a structure independent of the fresh air assembly 2, the face frame 11, and the panel 12.

[0038] The arrangement of the sealing component 3 at the second fresh air opening 111 is not limited herein to be mounted on the face frame 11, but only emphasizes the relative position between the sealing component 3 and the second fresh air opening 111. That is, the sealing component 3 may be mounted on the face frame 11 or other structures which is mounted at the second fresh air opening 111. When the sealing component 3 is only used to seal the gap between the face frame 11 and the fresh air assembly 2, the gap between the face frame 11 and the panel 12 can be sealed by glue, or by nature of the structure regarding the panel 12 and the face frame 11 themselves, etc. Similarly, when the sealing component 3 is only used to seal the gap between the face frame 11 and the panel 12, the gap between the fresh air assembly 2 and the face frame 11 can be sealed by glue, or by the nature of the structure of the fresh air assembly 2 and the face frame 11 themselves, etc.

[0039] According to the indoor unit 100 proposed by the present invention, the sealing component 3 is disposed at the second fresh air opening 111 of the face frame 11, and the sealing component 3 can seal the gap between the face frame 11 and the fresh air assembly 2 and / or the gap between the face frame 11 and the panel 12, so that the air outlet of the fresh air assembly 2 does not leak into the housing 1, thereby reducing the loss of the air output of the fresh air assembly 2, improving the air exchange capacity of the fresh air assembly 2, and simultaneously preventing the air from entering the interior of the indoor unit body to bring about noise and condensation.

[0040] Further, referring to Figs. 4, 7 and 8, the sealing component 3 includes a first sealing ring 31 sandwiched between the face frame 11 and the fresh air assembly 2.

[0041] In the present embodiment, in order to improve the sealing effect, the shape of the first sealing ring 31 is preferably similar to that of the second fresh air opening 111. For example, when the second fresh air opening 111 is arranged rectangular, the first sealing ring 31 can be also arranged rectangle, and the hollow part of the first sealing ring 31 is also rectangular, which is disposed corresponding to the second fresh air opening 111 to minimize shielding and facilitate a better outflow of fresh air. It can be appreciated that the first sealing ring 31 is sandwiched between the face frame 11 and the fresh air assembly 2, which means that the first sealing ring 31 is sandwiched between the edge of the face frame 11 near the second fresh air opening 111 and the outer wall surface of the fresh air assembly 2 near the second fresh air opening 111. The first sealing ring 31 can seal the gap between the face frame 11 and the fresh air assembly 2, so that when outdoor air enters the room through the fresh air assembly 2, the air can be prevented from flowing into the housing 1 from the gap between the face frame 11 and the fresh air assembly 2, thereby reducing the air output loss from the fresh air assembly 2, improving the air exchange capacity of the fresh air assembly 2, and simultaneously preventing the air from entering the interior of the indoor unit body to bring about noise and condensation.

[0042] Further, the sealing component 3 includes a second sealing ring 32 sandwiched between the face frame 11 and the panel 12.

[0043] In the present embodiment, in order to make the sealing effect better, the shape of the second sealing ring 32 is preferably similar to the shape of the second fresh air opening 111. For example, when the second fresh air opening 111 is arranged rectangular, the second sealing ring 32 can be also arranged rectangle, and the hollow part of the second sealing ring 32 is also rectangular, which is disposed corresponding to the second fresh air opening 111 to minimize shielding and facilitate a better outflow of fresh air. It can be appreciated that the second sealing ring 32 is sandwiched between the face frame 11 and the panel 12, which means that the second sealing ring 32 is sandwiched between the edge of the face frame 11 close to the second fresh air opening 111, and the edge of the panel 12 close to the first fresh air opening 121. The second sealing ring 32 can seal the gap between the face frame 11 and the panel 12, so that when outdoor air enters the room through the fresh air assembly 2, the air can be prevented from flowing into the housing 1 from the gap between the face frame 11 and the panel 12, thereby reducing the air output loss from the fresh air assembly 2, improving the air exchange capacity of the fresh air assembly 2, and simultaneously preventing the air from entering the interior of the indoor unit body to bring about noise and condensation.

[0044] The first sealing ring 31 and the second sealing ring 32 aforementioned may be two separate parts or two sealing rings formed by one sealing member. The first sealing ring 31 and the second sealing ring 32 may be integrally formed sealing rings or may be formed by splicing several sealing strips.

[0045] Further, the sealing component 3 includes a first seal ring 31, a second seal ring 32, and a third seal ring 33 connecting one end of the first seal ring 31 and one end of the second seal ring 32.

[0046] The first sealing ring 31, the second sealing ring 32 and the third sealing ring 33 are enclosed to form an open groove 34, and the face frame 11 is embedded in the open groove 34 corresponding to the edge of the second fresh air opening 111.

[0047] The first sealing ring 31 is tightly attached to the fresh air assembly 2, and the second sealing ring 32 is tightly attached to the panel 12.

[0048] In the present embodiment, it can be appreciated that the shape of the open groove 34 formed by enclosing the first sealing ring 31, the second sealing ring 32 and the third sealing ring 33 is mated to the shape of the edge of the face frame 11 corresponding to the second fresh air opening 111. The groove height of the open groove 34 may be equal to or slightly smaller than the edge thickness of the face frame 11 corresponding to the second fresh air opening 111 . By embedding the edge of the face frame 11 corresponding to the second fresh air opening 111 into the open groove 34, the gap between the face frame 11 and the panel 12 and the gap between the fresh air assembly 2 and the face frame 11 can be sealed at the same time, and the third sealing ring 33 enables the overall sealing effect better. The first sealing ring 31, the second sealing ring 32 and the third sealing ring 33 can be integrally formed, so that the installation of the sealing component 3 can be facilitated. During installation, only the edge of the face frame 11 corresponding to the second fresh air opening 111 needs to be embedded into the open groove 34, and the gap between the face frame 11 and the panel 12 and the gap between the face frame 11 and the fresh air assembly 2 can be sealed at the same time.

[0049] Further, one side of the first sealing ring 31 close to the fresh air assembly 2 is provided with a first installing protrusion 311. The fresh air assembly 2 is provided with a first groove 21 corresponding to the first installing protrusion 311, and the first installing protrusion 311 is embedded in the first groove 21.

[0050] In the present embodiment, the first installing protrusion 311 may be only one projection, a plurality of projections spaced circumferentially alike the first sealing ring 31, or a protruding ribs circumferentially around the first sealing ring 31. The number of the first installing protrusions 311 or the first grooves 21 may be more than one, and an appropriate number of the first installing protrusions 311 and the first grooves 21 may be designed according to the width of the first sealing ring 31 as well as the practical requirements. Correspondingly, the first groove 21 may be a plurality of spaced grooves or an annular groove. By arranging the first installing protrusion 311 on the first sealing ring 31, when the first sealing ring 31 is installed between the fresh air assembly 2 and the face frame 11, the first installing protrusion 311 is firstly fit in the first groove 21, and then the first sealing ring 31 and the fresh air assembly 2 are abutted against each other through pressure. As such, the installation of the first sealing ring 31 and the fresh air assembly 2 can be facilitated, the attachment is more tightly, and the dislocation and displacement can be prevented between the first sealing ring 31 and the fresh air assembly 2 in the meantime.

[0051] Further, the first installing protrusion 311 can be disposed obliquely. The inclination of the first installing protrusion 311 may be in any direction. When the first installing protrusion 311 is an installing protruded ribs disposed around the first sealing ring 31, the inclined position of the first installing protrusion 311 may be towards to or away from the third sealing ring 33. Therefore, the first installing protrusion 311 is obliquely arranged, which is not only convenient for molding and manufacturing, but also convenient for installing the first sealing ring 31 and provides a certain tolerance in installing deformation.

[0052] Further, one side of the second sealing ring 32 close to the panel 12 is provided with a second installing protrusion 321, the panel 12 is provided with a second groove 122 corresponding to the second installing protrusion 321, and the second installing protrusion 321 is embedded in the second groove 122.

[0053] In the present embodiment, the second installing protrusion 321 may be only one projection, a plurality of projections spaced circumferentially alike the second sealing ring 32, or a protruding ribs circumferentially around the second sealing ring 32. The number of the second installing protrusions 321 or the second grooves 122 may be more than one, and an appropriate number of the second installing protrusions 321 and the second grooves 122 may be designed according to the width of the second sealing ring 32 as well as the practical requirements. Correspondingly, the second groove 122 may be a plurality of spaced grooves or an annular groove. By arranging the second installing protrusion 321 on the second sealing ring 32, when the second sealing ring 32 is installed between the face frame 11 and the panel 12, the second installing protrusion 321 can be firstly installed in the second groove 122, and then the second sealing ring 32 is abutted against the panel 12 by pressure. Thus, the installation of the second sealing ring 32 and the panel 12 can be facilitated, and the attachment is more tightly, and the dislocation and displacement can also be prevented between the second sealing ring 32 and the panel 12.

[0054] Further, the second installing protrusion 321 is disposed obliquely. The inclination of the second installing protrusion 321 may be in any direction. When the second installing protrusion 321 is an installing protruded ribs disposed around the second sealing ring 31, the inclined position of the second installing protrusion 321 may be towards to or away from the third sealing ring 33. Therefore, the second installing protrusion 321 is obliquely arranged, which is not only convenient for molding and manufacturing, but also convenient for installing the second sealing ring 32 and provides a certain tolerance in installing deformation.

[0055] Further, one side of the second sealing ring 32 close to the face frame 11 is provided with a limiting groove 322, and the face frame 11 corresponding to the limiting groove 322 is provided with a limiting protrusion 112 which is in a limit fit with the limiting groove 322.

[0056] In the present embodiment, by providing the limiting groove 322 on the second sealing ring 32 and providing the limiting protrusion 112 in a limit fit with the limiting groove 322 on the face frame 11, the installation can be more stable and the second sealing ring 32 can be prevented from falling from the face frame 11, when the second sealing ring 32 is installed on the face frame 11. The cross-sectional shapes of the limiting protrusion 112 and the limiting groove 322 can be rectangular, dovetail-shaped, V-shaped, etc. They can be designed according to practical requirements, which are not specifically limited herein. In some other embodiments, one side of the second sealing ring 32 close to the face frame 11 is provided with a limiting protrusion 112, and at the face frame 11 corresponding to the limiting groove 322 is provided with a limiting groove 322 which is in a limit fit with the limiting protrusion 112. This may achieves a similar effect that prevents the second sealing ring 32 from falling from the face frame 11.

[0057] Further, referring to Figs. 8 and 10, one end of the first sealing ring 31 away from the third sealing ring 33 is provided with a guiding portion 312, and the guiding portion 312 is inclined towards the fresh air assembly 2 from the direction away from the third sealing ring 33.

[0058] In the present embodiment, the guiding portion 312 provided by the first sealing ring 31 can guide for the installation of the first sealing ring 31, and the inclined arrangement of the guiding portion 312 can facilitate the installation of the first sealing ring 31 into the gap between the fresh air assembly 2 and the face frame 11.

[0059] Another embodiment will now be described with reference to Fig. 5, Fig. 6, Fig. 9 and Fig. 10 in combination. The fresh air assembly 2 includes a cover 22, at least one inner wall surface 221 of the cover 22 is disposed obliquely from the face frame 11 to the panel 12, and the distance between the inner wall surface 221 and its opposite wall surface increases in a direction from the face frame 11 towards to the panel 12.

[0060] The side surface 331 is disposed obliquely of the third sealing ring 33 corresponding to the inner wall surface 221, and the inclined direction is consistent with that of the inner wall surface 221.

[0061] In the present embodiment, the cover 22 may include a fresh air screen, which plays a role in dust prevention and dust filtration. The fresh air screen is typically installed at the air outlet of the air passage, then the inclined inner wall surface 221 may also be the inner wall surface 221 of the fresh air screen. If the distance between the inclined inner wall surface 221 and its opposite wall surface is gradually increased in a direction from the surface frame 11 towards the panel 12, the inner wall surface 221 can play a role in guiding the air after flowing out of the air outlet, thereby enabling the flowing of the fresh air more smoothly. The inner wall surface 221 may be more than one and may be designed according to practical requirements. As long as the side surface 331 of the third sealing ring 33 corresponding to the inner wall surface 221 is disposed obliquely, and inclined direction of the side is consistent with that of the inner wall surface 221, the side surface 331 of the third sealing ring 33 may not hinder but guide the outflow of fresh air. In order to achieve a better air guiding effect and make the overall more uniform and aesthetic, it is preferable that the inclination angle of the side surface 331 and the inner wall surface 221 is the same.

[0062] Further, as shown in Fig. 3, the fresh air assembly 2 includes a cover 22, a fresh air duct (not shown) and a fan (not shown) provided in the cover 22. The fresh air duct (not shown) and the air passage of the air conditioner indoor unit 100 are arranged independently of each other. The fresh air duct (not shown) includes an air inlet (not shown) and an air outlet (not shown), the air inlet (not shown) is communicated with the outside, and the air outlet (not shown) is communicated with the second fresh air opening 111.

[0063] In the present embodiment, the cover 22 provides a fundamental room for installing a fan (not shown) placed therein, and in the meanwhile a fresh air duct (not shown) forms inside, which usually includes a scroll tongue and a scroll housing. The fresh air duct (not shown) and the air passage of the air conditioner indoor unit 100 are arranged independently of each other, so the fresh air introduced by the fresh air duct (not shown) will not affect the air with heat-exchanged in the indoor unit 100 of the air conditioner. The air inlet of the fresh air duct (not shown) can be communicated with the outdoor through the air passage to introduce outdoor fresh air into the fresh air duct (not shown). Outdoor fresh air is introduced into the air passage through the action of fans (not shown), and then flows into the room through the air outlet, the second fresh air opening 111 and the first fresh air opening 121 in sequence to complete the fresh air introduction. The fan (not shown) may be a centrifugal fan (not shown), a cross-flow fan (not shown), an axial flow fan (not shown), or the like, and is not specifically limited herein.

[0064] Further, as shown in Figs. 1 and 5, the panel 12 includes a panel body 123 and a fresh air outlet plate 124 connected to the panel body 123. The fresh air outlet plate 124 is disposed corresponding to the fresh air assembly 2, and the first fresh air opening 121 is disposed on the fresh air outlet plate 124.

[0065] In the present embodiment, the panel 12 is composed of a panel body 123 and a fresh air outlet plate 124, and the panel body 123 may be connected or spliced with the fresh air outlet plate 124 to form the panel 12. The fresh air outlet plate 124 may be rotatably mounted on the panel body 123, may be detachably connected to the panel body 123, or may be provided with an adjustable structure to realize the joint with the panel body 123, and the connection is not specifically limited herein.
