As shown in FIGS. 1 to 5 , the vertical air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 and at least one air guide 50 .

The casing 10 extends in a vertical column shape, that is, the casing 10 is in the shape of a strip extending in the up-down direction. At least one air duct 20 is defined in the casing 10, and the casing 10 is provided with at least one vertical first air supply port 11 and at least one extended air supply portion 141 (refer to the position marked with an ellipse in FIG. 3 ) . The casing 10 described in this embodiment includes a skeleton for constituting the basic frame of the indoor unit and body parts such as a volute and a volute tongue for defining the air duct 20 . The first air outlet 11 is used to blow the airflow in the casing 10 to the room to adjust the indoor air. The aforementioned air flow can be cold air produced by the vertical air conditioner indoor unit in cooling mode, hot air produced in heating mode, or fresh air introduced in fresh air mode. The number of the air duct 20 can be one or more.

The casing 10 is provided with an air inlet 13, and the air inlet 13 can be arranged on the rear surface of the casing 10 for introducing indoor airflow. In some embodiments, the vertical air conditioner indoor unit may be an indoor unit of an air conditioner that utilizes a vapor compression refrigeration cycle system for cooling/heating, and a heat exchanger 40 is disposed therein. The indoor air enters the casing 10 through the air inlet 13, 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 first air supply port 11 to regulate the indoor ambient air.

Each air guide 50 is a column extending vertically, and each air guide 50 is arranged at a first air supply port 11 to define an air outlet gap 201 with the inner wall of the air duct 20 adjacent to the first air supply port 11 , The airflow at the first air outlet 11 is blown to the indoor environment through the air outlet gap 201 . Specifically, both sides of each air guide 50 and the inner walls of both sides 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 be limited to an air outlet gap 201 with one side inner wall of the air duct 20, and the other side may be in close contact with the inner wall of the air duct 20, so that no air outlet gap is formed and no air can be discharged. , the scheme is not shown. The airflow is blown out through the air outlet gap 201 between the air guide 50 and the inner wall of the air duct 20, so that the airflow does 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.

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 achieve faster 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 indoor unit of the vertical air conditioner is configured such that: the air duct 20 is connected to the first air supply port 11, as shown in FIG. 3; or connected to the first air supply port 11 and the extended air supply part 141, as shown in FIG. That is to say, the air outlet direction of the air duct 20 is optional, and the air conditioner can choose to enable or disable the extended air supply unit 141, thereby changing the air outlet effect and making the air supply adjustment mode of the vertical air conditioner indoor unit more diverse. As shown in Figure 3, the air duct 20 is connected to the first air supply port 11, and the air is discharged from the first air supply port 11; The tuyere 11 is closed by the deflector 50, and the air is blown by the extended air supply part 141; or, as shown in Figure 5, the air duct 20 is connected to the first air supply port 11 and the extended air supply part 141, and the first air supply port 11 is opened, and the The first air blowing port 11 and the extended air blowing portion 141 blow air at the same time.

The expanded air supply portion 141 may be composed of a plurality of air diffuser holes 141a. The air volume of the diffuse air microholes 141a is very small, so that the air flow is very fine, and the human body feels very comfortable. For example, as shown in FIG. 1 , each air-diffusing microhole 141a is a vertical hole, and each air-diffusing microhole 141a is arranged in a horizontal direction. Certainly, each air-dispersing micro-hole may also be a round hole, a square hole, an elliptical hole or holes of other shapes. In addition, the extended air supply part 141 may also be a structure such as an outlet grille or an air supply hole.

In some embodiments, the housing 10 includes a first air channel wall and a second air channel wall, both of which define an air channel 20 . The outlet end of the first air duct wall constitutes an end of the first air blowing port 11 away from the extended air blowing portion 141 . The second air duct wall includes a second main body section 22 and an adjustment section 25 rotatably mounted on the second main body section 22 (the rotation axis is the x-axis). In this way, the air outlet direction of the air channel 20 can be changed by rotating the adjusting section 25 . Specifically, when the adjustment section 25 is rotated so that its end is between the first air supply port 11 and the expanded air supply portion 141 , the air channel 20 is connected to the first air supply port 11 , as shown in FIG. 3 . When the adjusting section 25 is rotated to make its end close to the end of the extended air supply part 141 away from the first air supply port 11, the air channel 20 is connected to the first air supply port 11 and the extended air supply part 141, as shown in Fig. 4 and Fig. 5 . Of course, a motor can be set to drive the adjustment section 25 to make it rotate. The motor is controlled by the main control board of the vertical air conditioner indoor unit. In some embodiments, as shown in FIGS. 3 to 5 , the first air duct wall includes a first main body section 21 and an end section 23 spaced apart from each other, and the interval between the first main body section 21 and the end section 23 constitutes the second Two air supply outlets 12. The function of the second air supply port 12 is the same as that of the first air supply port 11, and is used to discharge the airflow (heat exchange airflow or fresh air flow, etc.) in the air duct 20 to the room. At least one air deflector 60 is provided at the second air supply port 12 for opening and closing the second air supply port 12 and/or guiding its air outlet direction. For example, as shown in FIGS. 1 to 4 , each second air outlet 12 may be provided with an air guide plate 60 , and the rear side of the air guide plate 60 is pivotally mounted on the rear side of the second air outlet 12 . In this way, it is convenient to guide the air supply airflow toward the front left or the front right, as shown in FIG. 4 . Certainly, it is also possible to arrange a plurality of wind deflectors 60 side by side at each second air supply port 12 to guide the wind direction through linkage rotation. In addition, an air outlet structure such as an air outlet grill or a micro-hole plate may also be provided at the second air outlet 12 . In some embodiments, as shown in FIG. 1 to FIG. 5 , there are two air ducts 20 , and the two air ducts 20 are arranged side by side along the lateral direction (horizontal direction, that is, the left-right direction) of the casing 10 . The first air supply port 11 and the extended air supply portion 141 of each air duct 20 are open to the front, and are arranged side by side along the lateral direction of the casing 10, and the extended air supply portion 141 is closer to the side of the casing 10 than the first air supply port 11. horizontal center. Specifically, for the air channel 20 on the left side, its extended air supply part 141 is located on the right side of the first air supply port 11; .

The first air supply openings 11 and the expanded air supply parts 141 of the two air ducts 20 are open to the front, and the second air supply openings 12 of the two air ducts 20 are respectively open to lateral sides. In other words, the second air outlet 12 of the air channel 20 on the left opens to the left, and the second air outlet 12 of the air channel 20 on the right opens to the right. The number of the second air supply opening 12 may be one or more, and the second air supply opening 12 may also be in the shape of a vertical bar. The second air outlet 12 is not provided with a deflector 50, so the air outlet is smoother.

In this way, the indoor unit of the vertical air conditioner performs air supply with a small air volume through the first air supply port 11 and a plurality of diffused air holes 141a, and uses the second air supply port 12 to supply air with a large air volume. The combination of the three can obtain a variety of air supply modes . In the embodiment shown in Figures 1 to 3, each air channel 20 is only provided with a first air supply port 11 and a second air supply port 12, and the first air supply port 11 and the second air supply port 12 are vertical bars shape. Of course, each air duct 20 can also be provided with multiple first air supply ports 11 or multiple second air supply ports 12 so that the multiple first air supply ports 11 or the multiple second air supply ports 12 are arranged in the vertical direction.

In this way, the two second air supply ports 12 are used to supply large air volume to the left and right sides of the casing 10, so that the cooling/heating speed is faster and the human body will not be directly blown. The two first air outlets 11 and a plurality of air diffuser holes 141a are used to blow air forward. In short, the two kinds of air supply ports cooperate to make the air supply angle larger.

In some embodiments, referring to FIGS. 3 and 4 , the enclosure 10 includes a front center panel 14 that constitutes the front appearance thereof. The two transverse end sections of the front central panel 14 are respectively shielded at the outlets of the two air ducts 20, and are provided with a plurality of diffuse air micro-holes 141a to form two expanded air supply parts 141. Moreover, two air outlet gaps 201 are formed between the two lateral ends of the front central panel 14 and the two air guides 50 respectively. Specifically, the lateral end of the front central panel 14 may have a rearward flange 142 so that the air outlet gap 201 acts on the airflow for a longer distance. In other words, the air duct 20 has an opening facing forward, the part covered by the front central panel 14 constitutes the extended air supply part 141 , and the part not covered by the front central panel 14 constitutes the first air supply port 11 . Of course, the two lateral ends of the front central panel 14 also belong to the cabinet part defining the air duct 20 .

In this embodiment, the front central panel is used to form air-diffusing micro-holes 141a, which makes the casing structure of the vertical air conditioner indoor unit simpler, and also makes the appearance more complete and beautiful.

Fig. 6 is a schematic view of the vertical air conditioner indoor unit shown in Fig. 3 when both the first air supply port 11 and the second air supply port 12 are closed.

In this embodiment, the vertical air conditioner indoor unit selects different air supply modes according to different working conditions. For example, when the vertical air conditioner indoor unit is in the cooling mode, the first air supply port 11 can be selected to output air, and the second air supply port 12 and the air-dispersing micro-hole 141a will not supply air, so as to achieve a cool air supply experience without cold wind and avoid cold wind. Large air flow out makes the human body uncomfortable, as shown in Figure 3; or make the first air supply port 11 and a plurality of diffuse air microholes 141a supply air, so that the second air supply port 12 is closed to achieve a breeze effect with a larger air volume, as shown in Figure 5. In the heating mode, the first air supply port 11 can make no air flow or a small amount of air flow, so that a plurality of air-dispersing micro-holes 141a can emit air (but the air volume is small), and the air is mainly supplied by the second air supply port 12 on both sides. , so that the airflow on both sides blows to the left and right sides of the vertical air conditioner indoor unit respectively, and then turns forward after meeting the wall, forming a 180° enveloping air supply effect, so that users can feel stronger warmth and more comfort. Figure 4. When the indoor unit of the vertical air conditioner is in the shutdown state, the first air supply port 11 and the second air supply port 12 are both in the closed state, and the adjustment section 25 is rotated to a state not in communication with the diffused air microhole 141a, so that the casing 10 The various air supply channels are closed, as shown in Figure 6. Of course, it should be understood that the air supply modes selected above for the two working conditions are only some preferred solutions. The second air supply port 12 can also be selected for air supply when the air conditioner is cooling, and the first air supply port 11 can also be selected for heating. For air supply, the present invention does not make any limitation on the combination of air conditioner operating conditions and air supply modes. In addition, in the embodiments shown in FIG. 3 to FIG. 5 , the air supply modes of the left and right air ducts are the same, but this is not limited in the present invention, and the air supply modes of the left and right air ducts can also be set to be different.

As shown in Figure 3, for the embodiment in which two air ducts 20 are arranged, a vertically arranged cross-flow fan 80 can be provided at the entrance of each air duct 20, and a heat exchanger is arranged behind the two air ducts 20 40. Specifically, the heat exchanger 40 can be made U-shaped with an opening facing forward, so that the two cross-flow fans 80 are enclosed on the rear side and lateral sides, so as to make full use of the air volume of the two cross-flow fans 80 and make the heat exchanger 40 The heat exchange efficiency of the heater 40 is higher. Of course, the heat exchanger 40 can also be flat or in other shapes.

In some alternative embodiments, the vertical air conditioner indoor unit may only include one cross-flow fan 80 or other types of fans, and the one fan blows into the two air ducts 20 .

In some alternative embodiments, the indoor unit of the vertical air conditioner may also include two heat exchangers, so that each heat exchanger is arranged in one air duct 20 .

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

The end section 23 of the first air duct wall and the flange 142 at the end of the front central panel 14 constitute the aforementioned tapered section of the air duct 20 . Specifically, the flange 142 extends straight from the rear to the front, and the end section 23 gradually extends obliquely toward the flange 142 from the rear to the front, so that the distance between them becomes closer and closer to form a tapered section. When the adjustment section 25 of the second air channel wall is rotated to a position between the first air outlet 11 and the expanded air supply part 141 , the end of the adjustment section 25 is made to abut against the flange 142 . It is also possible to make the adjustment section 25 gradually away from the lateral center of the casing 10 from the rear to the front, so that the air passage section defined by the adjustment section 25 and the end section 23 of the first air passage wall is also a tapered section.

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 toward the center of the air flow during the outward flow process, and converges into one stream, making the wind force very strong and the air supply distance longer, which meets the needs of indoor units of vertical air conditioners. The demand for long-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.

In the embodiment of the present invention, the air guide 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 toward the air outlet gap 201, so as to force the airflow to accept the air duct. The aggregation guide of the tapered inner wall of 20 forms the final aggregation 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. Another 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 contribute to the two Aggregation of air streams.

In some embodiments, 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 . 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.

As shown in FIG. 7 , the deflector 50 is installed on the casing 10 through a rack and pinion mechanism. Specifically, the rack and pinion structure includes a motor 71 , a gear 72 and a rack 73 . The motor 71 drives the gear 72 to rotate. The gear 72 meshes with the rack 73 , and the rack 73 is fixed on the bottom of the deflector 50 . In some embodiments, each deflector 50 may be a hollow structure. In this way, the weight of the flow guiding member 50 is lighter, which facilitates its translation.
