Patent Description:
With surging demands of users on quality of life, air conditioners, which are widely used in daily life, have also been optimized accordingly. Fresh air assemblies have been introduced into indoor units of air conditioners, bring outside air into rooms and provide continuous and fresh air for closed indoor space, thus increasing the oxygen content of indoor air and eliminating air conditioner sickness.

However, a gap exists between the assembly of the fresh air assembly and the panel component. For example, the gap exists between the fresh air assembly and the face frame or between the panel and the face frame, which brings about an air leakage from the air outlet of the fresh air assembly. As such, the air output of the fresh air assembly has been reduced to some extent, and the air exchange capacity of the fresh air assembly is lowered. Further, such leakage may induce noise and condensation when the air enters the indoor unit.

The fresh air device comprises an air inlet module and a fan module communicating with the air inlet module. An air inlet cavity is defined in the air inlet module, and a pipeline connection portion communicating with the air inlet cavity is provided. The pipeline connection portion is connected to an outdoor fresh air inlet tube. An air supply fan is configured to intake, at an air inlet at the top portion of the housing, at least some of the air discharged by the centrifugal fan, and the air exchanges heat with a heat exchanger, and is then discharged via an air supply outlet at a lower portion of the housing.

The present invention provides an indoor unit of an air conditioner.

In at least one embodiment of the present invention, as shown in <FIG>, the air conditioner indoor unit <NUM> includes:.

In the present embodiment, the indoor unit of an air conditioner <NUM> may be a stand unit, a ceiling unit, a wall-mounted indoor unit, or the like. The housing <NUM> can provide a basic space for installation and a supporting structure for the indoor unit <NUM> of an air conditioner. The housing <NUM> may also include an air guiding plate, a chassis, etc. The face frame <NUM> 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 <NUM> is usually installed on the front side of the face frame <NUM> to maintain the overall consistency of the indoor unit <NUM>. The panel <NUM> can be detachably installed on the face frame <NUM> or movably connected to the face frame <NUM>. The specific structure is not limited herein, and an appropriate design can be selected according to practical requirements. The first fresh air opening <NUM> provided on the panel <NUM> may be an opening or may be of a plurality of small holes.

The fresh air assembly <NUM> is typically installed in the housing <NUM>, 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 <NUM> and the first fresh air opening <NUM> 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 <NUM> is generally provided with a cover <NUM> to form an air passage inside. The sealing component <NUM> can seal the gap between the cover <NUM> and the face frame <NUM>. The sealing component <NUM> may be consist of one or more of sealants, rubber sealing components, silica-gel sealing components, etc. The sealing component <NUM> can be a structure independent of the fresh air assembly <NUM>, the face frame <NUM>, and the panel <NUM>.

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

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

Further, referring to <FIG>, <FIG> and <FIG>, the sealing component <NUM> includes a first sealing ring <NUM> sandwiched between the face frame <NUM> and the fresh air assembly <NUM>.

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

Further, the sealing component <NUM> includes a second sealing ring <NUM> sandwiched between the face frame <NUM> and the panel <NUM>.

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

The first sealing ring <NUM> and the second sealing ring <NUM> aforementioned may be two separate parts or two sealing rings formed by one sealing member. The first sealing ring <NUM> and the second sealing ring <NUM> may be integrally formed sealing rings or may be formed by splicing several sealing strips.

Further, the sealing component <NUM> includes a first seal ring <NUM>, a second seal ring <NUM>, and a third seal ring <NUM> connecting one end of the first seal ring <NUM> and one end of the second seal ring <NUM>.

The first sealing ring <NUM>, the second sealing ring <NUM> and the third sealing ring <NUM> are enclosed to form an open groove <NUM>, and the face frame <NUM> is embedded in the open groove <NUM> corresponding to the edge of the second fresh air opening <NUM>.

The first sealing ring <NUM> is tightly attached to the fresh air assembly <NUM>, and the second sealing ring <NUM> is tightly attached to the panel <NUM>.

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

Further, one side of the first sealing ring <NUM> close to the fresh air assembly <NUM> is provided with a first installing protrusion <NUM>. The fresh air assembly <NUM> is provided with a first groove <NUM> corresponding to the first installing protrusion <NUM>, and the first installing protrusion <NUM> is embedded in the first groove <NUM>.

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

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

Further, one side of the second sealing ring <NUM> close to the panel <NUM> is provided with a second installing protrusion <NUM>, the panel <NUM> is provided with a second groove <NUM> corresponding to the second installing protrusion <NUM>, and the second installing protrusion <NUM> is embedded in the second groove <NUM>.

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

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

Further, one side of the second sealing ring <NUM> close to the face frame <NUM> is provided with a limiting groove <NUM>, and the face frame <NUM> corresponding to the limiting groove <NUM> is provided with a limiting protrusion <NUM> which is in a limit fit with the limiting groove <NUM>.

In the present embodiment, by providing the limiting groove <NUM> on the second sealing ring <NUM> and providing the limiting protrusion <NUM> in a limit fit with the limiting groove <NUM> on the face frame <NUM>, the installation can be more stable and the second sealing ring <NUM> can be prevented from falling from the face frame <NUM>, when the second sealing ring <NUM> is installed on the face frame <NUM>. The cross-sectional shapes of the limiting protrusion <NUM> and the limiting groove <NUM> 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 <NUM> close to the face frame <NUM> is provided with a limiting protrusion <NUM>, and at the face frame <NUM> corresponding to the limiting groove <NUM> is provided with a limiting groove <NUM> which is in a limit fit with the limiting protrusion <NUM>. This may achieves a similar effect that prevents the second sealing ring <NUM> from falling from the face frame <NUM>.

Further, referring to <FIG> and <FIG>, one end of the first sealing ring <NUM> away from the third sealing ring <NUM> is provided with a guiding portion <NUM>, and the guiding portion <NUM> is inclined towards the fresh air assembly <NUM> from the direction away from the third sealing ring <NUM>.

In the present embodiment, the guiding portion <NUM> provided by the first sealing ring <NUM> can guide for the installation of the first sealing ring <NUM>, and the inclined arrangement of the guiding portion <NUM> can facilitate the installation of the first sealing ring <NUM> into the gap between the fresh air assembly <NUM> and the face frame <NUM>.

Another embodiment will now be described with reference to <FIG>, <FIG>, <FIG> and <FIG> in combination. The fresh air assembly <NUM> includes a cover <NUM>, at least one inner wall surface <NUM> of the cover <NUM> is disposed obliquely from the face frame <NUM> to the panel <NUM>, and the distance between the inner wall surface <NUM> and its opposite wall surface increases in a direction from the face frame <NUM> towards to the panel <NUM>.

The side surface <NUM> is disposed obliquely of the third sealing ring <NUM> corresponding to the inner wall surface <NUM>, and the inclined direction is consistent with that of the inner wall surface <NUM>.

In the present embodiment, the cover <NUM> 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 <NUM> may also be the inner wall surface <NUM> of the fresh air screen. If the distance between the inclined inner wall surface <NUM> and its opposite wall surface is gradually increased in a direction from the surface frame <NUM> towards the panel <NUM>, the inner wall surface <NUM> 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 <NUM> may be more than one and may be designed according to practical requirements. As long as the side surface <NUM> of the third sealing ring <NUM> corresponding to the inner wall surface <NUM> is disposed obliquely, and inclined direction of the side is consistent with that of the inner wall surface <NUM>, the side surface <NUM> of the third sealing ring <NUM> 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 <NUM> and the inner wall surface <NUM> is the same.

Further, as shown in <FIG>, the fresh air assembly <NUM> includes a cover <NUM>, a fresh air duct (not shown) and a fan (not shown) provided in the cover <NUM>. The fresh air duct (not shown) and the air passage of the air conditioner indoor unit <NUM> 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 <NUM>.

In the present embodiment, the cover <NUM> 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 <NUM> 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 <NUM> 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 <NUM> and the first fresh air opening <NUM> 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.

Further, as shown in <FIG> and <FIG>, the panel <NUM> includes a panel body <NUM> and a fresh air outlet plate <NUM> connected to the panel body <NUM>. The fresh air outlet plate <NUM> is disposed corresponding to the fresh air assembly <NUM>, and the first fresh air opening <NUM> is disposed on the fresh air outlet plate <NUM>.

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