The invention provides an air conditioner indoor unit. The indoor unit of the air conditioner is an indoor part of the air conditioner, and is used for adjusting indoor air, such as cooling/heating, dehumidification, introducing fresh air, and the like. The present invention does not limit the style of the air conditioner indoor unit, which can be wall-mounted, vertical, ceiling, etc. Figures 1 to 18 illustrate the embodiments of the vertical air conditioner indoor unit.

It should be noted that the above three embodiments are only some preferred embodiments of the present invention, and only some of the air supply modes of the embodiments are shown in the figure, and some embodiments and some air supply modes are not clearly listed. out introduction.

The air conditioner indoor unit in the embodiment of the present invention includes a casing 10 , and the casing 10 defines at least one air duct 20 . The casing 10 described in the embodiment of the present invention includes a skeleton for constituting the basic frame of the indoor unit and body components such as a volute and a volute tongue for defining an air duct 20 . A plurality of side-by-side air supply ports are formed at the outlet of each air channel 20 for blowing the conditioned air in the casing 10 to the indoor environment. In the first embodiment, the multiple air supply ports refer to the first air supply port 11 and the second air supply port 12. In the second and third embodiments, the multiple air supply ports refer to the first air supply port 11, the second air supply port The air supply port 12 and the third air supply port 13. The regulated airflow can be the cold air produced by the indoor unit of the air conditioner in the cooling mode, or the hot air produced in the heating mode, or the fresh air introduced in the fresh air mode. The number of the air duct 20 can be one or more. An air inlet can be opened on the casing 10 for introducing indoor airflow. In some embodiments, the indoor unit of the air conditioner may be an indoor unit of the air conditioner that utilizes a vapor compression refrigeration cycle system for cooling/heating, and a heat exchanger 40 is disposed therein. Indoor air enters the casing 10 through the air inlet, and after exchanging heat with the heat exchanger 40, enters the air duct 20 under the action of the fan, and then blows to the indoor environment through the air supply port to adjust the indoor ambient air.

Each air channel 20 is defined by a first air channel wall 21 and a second air channel wall 22 arranged at intervals. That is, the space between two air duct walls constitutes an air duct 20 . The position of the outlet end of the first air channel wall 21 and/or the second air channel wall 22 can be adjusted, so that the air channel 20 can selectively communicate with one or more of the plurality of air supply ports. That is, only the position of the outlet end of the first air channel wall 21 may be adjustable, or only the position of the outlet end of the second air channel wall 22 may be adjustable, or the positions of the outlet ends of both air channel walls may be adjustable. The position of the outlet end of the air duct wall is not fixed, so that it can be adjusted to change the direction of the outlet of the air duct 20 to make it face different air supply outlets, and also change the size of the outlet of the air duct 20 to change the direction of the air delivery port. The number of vents.

This makes the air supply adjustment mode of the indoor unit of the air conditioner very rich, which is convenient for the indoor unit of the air conditioner to adjust different air supply modes according to different operating conditions and user needs, enable the corresponding air supply outlet, and disable other air supply outlets to change The overall wind direction, air volume, etc. of the indoor unit of the air conditioner, so that users can obtain a better air supply experience. For example, increase or decrease the enabled air supply outlets according to the demand for air volume, and enable specific air supply outlets according to the needs of users. The specific air supply outlets can be air supply outlets capable of micro-hole air outlet, or aggregated air supply outlets with long air supply distances , or have a special orientation of the air outlet, etc.

In some embodiments, the first air duct wall 21 can be made to include a first main body section 211 and a first adjustment section 212 (the rotation axis is x1) which are rotationally connected along the airflow direction, and/or the second air duct wall 22 can be arranged along the airflow direction. The orientation includes the rotationally connected second body section 223 and the second adjustment section 224 (axis of rotation x2). The first main body section 211 and the first adjustment section 212 connect to form a complete first air duct wall 21 , and the first main body section 211 is located at the upstream side of the airflow compared to the first adjustment section 212 . The second main body section 223 and the second adjustment section 224 are connected to form a complete second air duct wall 22 , and the second main body section 223 is located at the upstream side of the airflow compared to the second adjustment section 224 . "And/or" means: one of the two conditions can be satisfied (refer to the first embodiment), or both conditions can be satisfied (refer to the second and third embodiments). In this way, the air-conditioning indoor unit can adjust the position of the outlet end of the first air duct wall 21 and/or the second air duct wall 22 by rotating the first adjustment section 212 and/or the second adjustment section 224, so that the air duct 20 can selectively One or more of the multiple air outlets are grounded. The first air channel wall 21/second air channel wall 22 can be regarded as a flexible structure, the structure is very ingenious, and the adjustment is very convenient. Of course, the rotation of the first adjusting section 212 and the second adjusting section 224 can be driven by corresponding motors.

Some optional air supply modes of the air conditioner indoor unit according to the first embodiment of the present invention will be introduced below with reference to FIG. 1 to FIG. 5 .

Fig. 1 is a schematic diagram of the air-conditioning indoor unit in the first embodiment of the present invention when both air supply ports are closed; Fig. 2 is a schematic diagram of the air-conditioning indoor unit shown in Fig. 1 when the air duct 20 is only connected to the first air supply port 11; Fig. 3 is a schematic diagram of the air-conditioning indoor unit shown in FIG. 2 after the deflector 50 is moved to enlarge the air outlet gap 201; FIG. 4 is a schematic diagram of the air-conditioning indoor unit shown in FIG. 1 when the air duct 20 is connected to two air outlets ; FIG. 5 is a schematic diagram of the air-conditioning indoor unit shown in FIG. 4 when the first air outlet 11 is opened by the deflector 50 .

As shown in Figures 1 to 5, two air supply ports are formed at the outlet of each air channel 20, namely the first air supply port 11 and the second air supply port 12, with the third air channel wall 23 as the boundary between the two. . The first air duct wall 21 includes a first body section 211 and a first adjustment section 212 which are rotatably connected along the airflow direction. The position of the outlet end of the second air channel wall 22 is not adjustable, and its outlet end is connected to the end of the first air supply port 11 away from the second air supply port 12 (shown as the left end of the first air supply port 11), so as to adjust When the end of the section 212 (constituting the outlet end of the first air duct wall 21) is connected to the end of the second air supply port 12 away from the first air supply port 11, the air duct 20 is connected to the first air supply port 11 and the second air supply port 12, As shown in Fig. 1, Fig. 4 and Fig. 5; when the end of the first regulating section 212 is connected to the third air duct wall 23, the air duct 20 is only connected to the first air supply port 11, as shown in Fig. 2 and Fig. 3 .

In some optional structures, as shown in FIGS. 1 to 5 , a deflector 50 is provided at the first air outlet 11 , and an air outlet gap is defined between the deflector 50 and the inner wall of the air duct 20 adjacent to the first air outlet 11 201, so that the air at the first air outlet 11 is blown to the indoor environment through the air outlet gap 201. It should be noted that the third air duct wall 23 is only used to separate the two air supply ports, and its size may be significantly smaller than the first air duct wall 21 and the second air duct wall 22, but it is still defined as an "air duct wall", When the end of the first regulating section 212 is connected to the third air channel wall 23, the third air channel wall 23 also has the function of defining the air channel 20, but only the short section of the air channel 20 adjacent to the first air supply port 11 is limited. . The wall surface of the third air channel wall 23 facing the deflector 50 also belongs to the aforementioned "inner wall of the air channel 20", and is also used to define the aforementioned "air outlet gap 201". The same is true for the subsequent fourth air duct wall 24 and fifth air duct wall 25 . The airflow is blown out through the air outlet gap 201, so that the airflow will not directly blow the human body with a large amount of air, making the human body feel more comfortable. The smaller the air outlet gap 201 is designed, the finer the air outlet airflow and the smaller the wind feeling.

Specifically, as shown in Figures 1 to 5, the casing 10 is extended in a vertical column, that is, the air-conditioning indoor unit is a vertical air-conditioning indoor unit, the first air supply port 11 is in the shape of a vertical bar, and the flow guide 50 is A column that extends vertically. Both sides of the flow guide 50 and the inner walls of the air duct 20 define an air outlet gap 201 , as shown in FIG. 3 . Alternatively, only one side of each flow guide 50 may define an air outlet gap 201 with one side inner wall of the air duct 20, and the other side is in close contact with the inner wall of the air duct 20, so that no air outlet gap 201 is formed, and no air outlet gap 201 can be formed. Wind, the scheme is not shown. Of course, the second air outlet 12 is also preferably in the shape of a vertical strip.

In some embodiments, as shown in FIG. 3 , the two sides of each deflector 50 and the inner walls on both sides of the air duct 20 define an air outlet gap 201 , and the inner wall of the air duct 20 adjacent to the first air supply port 11 It is tapered so that the cross section of the air duct 20 gradually becomes smaller along the airflow direction. In other words, near the first air outlet 11 , along the airflow direction, the cross section of the air duct 20 gradually becomes smaller. In this way, the airflows flowing out of the two air outlet gaps 201 are guided by the tapered part of the inner wall of the air duct 20 and aggregated into one stream outside the first air supply port 11 to form a combined air supply effect.

Due to the addition of the air guide 50, the flow cross section of the air outlet gap 201 must be smaller than the original flow cross section of the air duct 20, which makes the air flow faster. Under the guidance of the tapered inner wall of the air duct 20, the high-speed air flow gradually converges towards the center of the air flow during the outward flow process, and converges into one strand, making the wind force very strong and the air supply distance longer, which meets the requirements of the indoor unit of the air conditioner. The demand for distance air supply and strong air supply also makes the air supply range larger, making the cooling/heating speed more uniform throughout the indoor space, and making the human body feel more comfortable. The deflector 50 not only defines the air outlet gap 201 with the inner wall of the air duct 20, which plays a role in increasing the wind speed, but also just can force the airflow to flow towards the air outlet gap 201, so as to force the airflow to accept the tapered inner wall of the air duct 20. The aggregated guide forms the final aggregated air supply effect.

In some embodiments, as shown in FIG. 3 , the cross-sectional outer profile of each deflector 50 can be olive-shaped or elliptical, and its two tips are respectively facing the inner walls of the two sides of the air duct 20 . Both the olive shape and the ellipse are composed of two convex curved surfaces as a whole, and the connection between the two large curved surfaces forms two tips. A convex curved surface faces the inside of the air duct 20 , and the airflow is smoothly distributed to the two horizontal tips of the air guide 50 , that is, the two air outlet gaps 201 , by using the convex curved surface. The other convex curved surface faces the first air supply port 11, and the airflow can guide the airflow at the two air outlet gaps 201 to flow along the surface of the convex curved surface toward its center under the effect of the Coanda effect, and help the two Aggregation of air streams.

Further, the position of each deflector 50 can be changed (including translation, rotation or compound movement) to adjust the size of the air outlet gap 201 to change its flow area (including adjusting the flow area to 0, such as FIG. 4 , make the deflector 50 close the first air outlet 11 ), so as to adjust the wind force of the first air outlet 11 . Specifically, the wind force can be increased by increasing the air outlet gap 201 to cool/heat more quickly; the wind force can be reduced by reducing the air outlet gap 201 (from the state shown in Figure 2 to the state shown in Figure 3) to simulate natural wind, Make airflow comfort even higher.

Specifically, for example, as shown in FIGS. 1 to 5 , each deflector 50 is translatably mounted on the casing 10 to approach or move away from the first air outlet 11 in translation, so as to adjust the air volume of the air outlet gap 201 . Specifically, the deflector 50 can be installed on the casing 10 through a motor+rack and pinion mechanism, so as to drive it to translate. Adjusting the air volume of the air outlet gap 201 includes adjusting the air outlet gap 201 to zero. Specifically, the air guide 50 is located behind the first air supply port 11. Since the flow cross section of the air duct 20 at the first air supply port 11 is tapered, when the air guide 50 is moved backward, the air guide 50 and the wind The distance between the inner walls of the channel 20 becomes larger, so that the air outlet gap 201 becomes larger. When the deflector 50 is moved forward, the distance between the deflector 50 and the inner wall of the air duct 20 becomes smaller, so that the air outlet gap 201 becomes smaller. When the deflector 50 is moved forward so that its lateral ends abut against the inner wall of the air duct 20 , the air outlet gap 201 disappears, and the first air outlet 11 is closed. The wind force can be increased by increasing the air outlet gap 201 to achieve rapid cooling/heating; the wind force can be reduced by reducing the air outlet gap 201 to simulate natural wind and make the air flow more comfortable. The air conditioner operates in cooling mode, and when there are elderly people, children, pregnant women and other people who cannot withstand forced cooling in the room, you can choose to reduce the wind power to operate.

The second air supply port 12 may be provided with an air guiding swing vane 60 for opening and closing the second air supply port 12 and/or guiding its air outlet direction. Both the first air supply port 11 and the second air supply port 12 can be opened forward, so that the wind guide vane 60 guides the air to blow forward, left or right. Of course, the orientations of the first air outlet 11 and the second air outlet 12 can also be different, such as one facing forward and the other facing left (or right), and details will not be repeated here. In addition, an air outlet structure such as an air outlet grille or a micro-hole plate may also be provided at the second air supply port 12 to replace the air guide swing vane 60 .

To sum up, the air-conditioning indoor unit of the first embodiment of the present invention uses the first air supply port 11 as a collective air supply port, and uses the second air supply port 12 as a conventional air outlet. Air conditioner indoor units can choose different air supply modes according to different working conditions. For example, you can choose to let the air out from the first air supply port 11, and the second air supply port 12 does not supply air, as shown in Figure 2; or further translate the deflector 50 to make the air outlet gap 201 smaller, so as to reduce the air volume, as shown in Figure 3 or make the air passage 20 communicate with two air supply ports, but make the first air supply port 11 closed by the deflector 50, so that only the second air supply port 12 is discharged, as shown in Figure 4; or, make the air passage 20 communicate with two The air supply port, but the first air supply port 11 is closed by the deflector 50, so that both the first air supply port 11 and the second air supply port 12 are used for air supply.
