This structure breaks through the routine and is very novel and ingenious. The non-exchanging air mixes with the exchanging air in front of the vertical air conditioner indoor unit. The non-heat exchange air flow is one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow. When the non-heat-exchanging air is indoor air, it mixes with the heat-exchanging air to form a mixed air. Compared with the heat-exchanging air, the temperature of the mixed air is closer to room temperature, with higher comfort and softer wind feeling, which also makes the air volume and The wind speed increases, and the air supply distance is longer.

The outlet air flow of the column shell or the second column shell makes the indoor air mix in a larger amount and at a faster mixing speed, forming a stronger air mixing effect. Moreover, this also speeds up the indoor cooling/heating speed, improves the energy efficiency of the air conditioner, and achieves the effect of energy saving and emission reduction.

Furthermore, the utility model adjusts the flow area of the induced air interval by setting the air door, so as to facilitate the adjustment of the mixing amount of indoor air, thereby adjusting the outlet air temperature. Of course, when the user chooses to adjust the flow area of the induced air compartment to zero, that is, to close the induced air compartment, the induced air function of the induced air compartment can be turned off.

Further, in the indoor unit of the vertical air conditioner of the present invention, the second column shell is rotatably installed on the lower column shell around the vertical axis, so that the orientation of the second air outlet can be adjusted. Moreover, the included angle between the non-heat exchange air flow and the heat exchange air flow can also be adjusted accordingly, thereby changing the intersection position of the two. Moreover, by making the second column housing rotatable as a whole, there is no need to design an air guiding structure at the second air outlet, so that the appearance of the second column housing is more concise.

The utility model provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of the split air conditioner, which is used to adjust the indoor air, such as cooling/heating, dehumidification, introducing fresh air, etc. The vertical air conditioner indoor unit can be a conventional floor-standing cabinet or a vertical wall-mounted unit.

Fig. 1 is a schematic front view of a vertical air conditioner indoor unit according to a first embodiment of the present invention, and Fig. 2 is an enlarged cross-sectional view along N-N of Fig. 1 .

As shown in FIG. 1 and FIG. 2 , the vertical air conditioner indoor unit of the first embodiment of the present invention may generally include a first column housing 10 and a second column housing 20 .

The first cylindrical shell 10 is in the shape of a vertical column, that is, a hollow cylindrical shell. The first column housing 10 is provided with a first air outlet 12 for blowing out heat exchanging air. The "heat exchange air flow" refers to the air flow that completes heat exchange with the heat exchanger 17 of the air conditioner and is used to adjust the indoor temperature. The heat exchanger 17 is connected with the compressor, the heat exchanger of the outdoor unit, the throttling device and other refrigeration components through pipelines to form a vapor compression refrigeration cycle system. When the indoor unit of the vertical air conditioner is in the cooling mode, the heat exchange airflow is cold air; when the indoor unit of the vertical air conditioner is in the heating mode, the heat exchange airflow is hot air. The heat exchange air is blown to the indoor environment through the first air outlet 12 to complete the cooling and heating of the indoor environment.

The second cylindrical shell 20 is in the shape of a vertical column, that is, a hollow cylindrical shell. The second column shell 20 defines a second air outlet 22 for blowing out non-heat exchange air. Specifically, the non-heat exchange air flow can be one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow, and its role is to assist in adjusting the indoor environment.

There are some double-column vertical air-conditioning indoor units in the air-conditioning field, but their two column shells are both used to blow out heat-exchanging airflow, and the form is very single. The vertical air conditioner indoor unit of the utility model embodiment is designed with a second column shell 20 juxtaposed with the first column shell 10 to be specially used for blowing out the non-heat exchange air flow. This structure breaks through the routine and is very novel and ingenious. In addition, since there is no need to install a heat exchanger in the second column shell 20, the second column shell 20 can be designed thinner, making it significantly thinner than the first column shell 10. It also makes the appearance of the vertical air conditioner indoor unit more novel and unique, which improves the competitiveness of the product in terms of appearance.

As shown in Figures 1 and 2, the first air outlet 12 is opened on the front side of the first column shell 10, and the second air outlet 22 is opened on the front side of the second column shell 20 to allow non-heat exchange air flow in the vertical The heat exchange air is mixed in front of the air conditioner indoor unit.

The appearance difference of the existing vertical air conditioner indoor units is not obvious, and the air supply experience is not good, causing many complaints from users. Especially when the air conditioner is cooling, it is often felt that the temperature of the air outlet is low and the wind speed is high, and the cold wind blows directly on the human body, causing the user to feel uncomfortable. That is to say, the wind is too "hard" and not soft enough.

In the embodiment of the utility model, the indoor unit of the vertical air conditioner uses the first column shell 10 to blow out the heat-exchanging air, and uses the second column shell 20 to blow out the non-heat-exchanging air, and the non-heat-exchanging air is mixed into the heat-exchanging air in front of the vertical air-conditioning indoor unit airflow. When the non-heat-exchanging air is indoor air, it mixes with the heat-exchanging air to form a mixed air. Compared with the heat-exchanging air, the temperature of the mixed air is closer to room temperature, with higher comfort and softer wind feeling, which also makes the air volume and The wind speed increases, and the air supply distance is longer. When the second column shell 20 blows out fresh air flow, purified air flow, humidified air flow or water washing air flow and other regulated airflows, these regulated airflows can be mixed with the heat exchange airflow earlier and more to enhance the mixing rate and make it more efficient. Spreads well throughout the room.

Further, as shown in FIG. 2 , the second column shell 20 and the first column shell 10 can be arranged in the transverse direction, and the air-introduction space 13 is formed between them. The front and rear of the air-introduction interval 13 are connected to the indoor environment. The "horizontal" has been marked in the figure, and the left-right direction perpendicular to the front-to-back direction of the vertical air conditioner indoor unit is the "horizontal".

When the indoor unit of the vertical air conditioner in the embodiment of the utility model is running, the first column housing 10 and the second column housing 20 can be turned on for air supply alternatively or at the same time. When the first air outlet 12 and/or the second air outlet 22 blow out the air, relying on the negative pressure to drive the indoor air in the air-introduction compartment 13 to flow forward, so that the indoor air behind the indoor unit of the vertical air conditioner passes through the air-introduction compartment 13 It flows forward to mix with the air flow out of the first column shell 10 or the second column shell 20 to form the air-drainage mixing effect. Compared with the heat exchange airflow, the temperature of the mixed airflow is closer to the room temperature, with higher comfort and softer wind feeling, which also increases the air volume and wind speed, and the air supply distance is longer. Especially when the indoor air is also blown out from the second column shell 20, the indoor air can be mixed in a larger amount and mixed in at a faster speed, which can achieve a stronger air mixing effect and make the air flow closer to the room temperature.

As shown in FIG. 2 , the ratio of the lateral width of the second cylindrical case 20 to the lateral width of the first cylindrical case 10 can be made smaller than 1/2. The width refers to the distance between two points on the outer walls of the second cylindrical shell 20 or the first cylindrical shell 10 in the lateral direction that are farthest from each other in the lateral direction. The ratio of the depth dimension of the second column case 20 along the front-to-rear direction to the depth dimension of the first column case 10 along the front-to-rear direction is less than 1/2, which refers to the front and rear sides of the second column case 20 or the first column case 10 The distance between the two furthest points of the outer wall in the front-to-back direction. In this way, the size difference between the two is large enough to form a differentiated appearance of double columns. The front and rear positions of the second air outlet 22 and the first air outlet 12 can be aligned or substantially aligned, for example, the distance between the two is not more than 5 cm, so that the non-heat exchange air flow and the heat exchange air flow can be better mixed.

As shown in FIG. 2 , a second air duct 25 communicating with the second air outlet 22 is provided in the second column housing 20 to guide the non-heat exchange air flow in the second column housing 20 to the second air outlet more smoothly. 22 places. The distance between the two lateral side walls 251 and 252 of the second air channel 25 gradually decreases from the back to the front, forming a tapered shape. This tapered air duct can accelerate the air flow, so that the non-heat exchange air can be blown out of the second air outlet 22 faster, which can compensate for the lack of a fan in the second column shell 20 to give the wind speed. negative impact.

As shown in Figure 2, the air-inducing interval 13 can be made to gradually expand from the back to the front, so that the air outlet airflow of the first air outlet 12 and the second air outlet 22 can be better in the air. Negative pressure is formed in the outlet area of the air-inducing space 13, so that the air flow in the air-inducing space 13 is larger.

Figure 3 is an enlarged view of A in Figure 2, Figure 4 is a schematic diagram of the indoor unit of the vertical air conditioner shown in Figure 2 when it is switched to the left-facing air supply mode, and Figure 5 is the indoor unit of the vertical air conditioner shown in Figure 2 switched to the right Schematic diagram of air supply mode.

As shown in FIG. 2 to FIG. 5 , a second air guide member 26 for guiding the second air outlet 22 in a horizontal air outlet direction is mounted on the second column housing 20 . "Guiding the horizontal air outlet direction" refers to changing the angle between the air outlet direction and the front-to-back direction, such as making the air outlet air flow to the front, to the left front, to the right front, and so on. In addition, a first air guide member 16 for guiding the first air outlet 12 in a transverse air outlet direction is mounted on the first column housing 10 .

The vertical air conditioner indoor unit can change the angle between the non-heat exchange airflow and the heat exchange airflow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, and then change the intersection position of the two. Specifically, the larger the angle between the heat exchange airflow direction and the heat exchange airflow direction, the closer the intersection position is, that is, the closer to the vertical air conditioner indoor unit; the smaller the angle, the farther the intersection position is, that is, the farther the vertical air conditioner Air conditioner indoor unit. The indoor unit of the vertical air conditioner can adjust the above-mentioned intersection position according to the position of the human body, so as to avoid the intersection position being close to the human body and causing discomfort to the human body.

In addition, the indoor unit of the vertical air conditioner can also be configured to: use the second air guide member 26 to adjust the lateral air outlet direction of the second air outlet 22 so that the non-heat exchange air flow can flow into the heat exchange air flow of the first air outlet 12 . That is, when the first air guide member 16 changes the outlet direction of the heat exchange air flow, the second air guide member 26 is controlled to act so as to ensure that the non-heat exchange air flow can always flow into the heat exchange air flow. For example, as shown in FIG. 2 , when the first wind guiding member 16 swings forward, the second wind guiding member 26 guides the wind forward. As shown in FIG. 4 , when the first wind guiding member 16 swings to the left, the second wind guiding member 26 guides the wind to the left. As shown in FIG. 5 , when the first air guide member 16 swings to the right, the second air guide member 26 guides the wind to the right. The main control board of the air conditioner can be electrically connected with the motors of the second air guide part 26 and the first air guide part 16 at the same time, so as to control the coordinated action of the two.

As shown in FIG. 3 , the second air guiding component 26 may include a first plate body 261 and a second plate body 262 arranged at intervals in the transverse direction. Certainly, the connection between the second plate body 262 and the first plate body 261 is through other structures, which are not shown in FIG. 3 . The end of the first board 261 close to the second board 262 has a bent portion 2611 bent backward, and the air guide channel 260 is formed between the bent portion 2611 and the second board 262 and the distance from the back to the front is tapered. The second air guide member 26 is rotatably mounted on the second column housing 20 around the vertical axis x, so as to change the lateral air outlet direction of the second air outlet 22 by adjusting the relative position of the air guide channel 260 and the second air outlet 22 .

For example, as shown in FIG. 2 and FIG. 3 , when the air guide channel 260 is facing the second air outlet 22 , the non-heat exchange air is guided to blow straight ahead. As shown in FIG. 4 , the second air guide member 26 is rotated clockwise relative to the state shown in FIG. 2 , so that the air guide channel 260 faces to the left front, so as to guide the non-heat exchange airflow to blow out to the left front. As shown in FIG. 5 , the second air guide member 26 is rotated counterclockwise relative to the state shown in FIG. 2 , so that the air guide passage 260 is directed to the right front, so as to guide the non-heat exchange airflow to blow out to the right front. The structure of the air guide in this embodiment is very simple, and it occupies very little space, and is especially suitable for the narrow shape of the second air outlet 22 , and the design is very ingenious.

As shown in FIG. 3 , a second air passage 25 communicating with the second air outlet 22 can be provided in the second column housing 20 . One lateral sidewall 251 of the second air channel 25 defines a receiving groove 2512 , and the other lateral sidewall 252 defines a recessed portion 2523 . When the second air guide member 26 rotates to a lateral limit angle, the first plate body 261 is extended into the receiving groove 2512 so that the air guide surface of the bent portion 2611 is flat with the surface of the lateral side wall 251 of the second air duct 25 As shown in FIG. 4 , the air flow enters the air guide channel 260 from the second air channel 25 more smoothly. Similarly, when the second wind guide member 26 rotates to another lateral limit angle, the second plate body 262 is embedded in the recessed portion 2523, so that the wind guide surface of the second plate body 262 and the lateral side wall of the second air duct 25 The surface of 252 is even, as shown in Figure 5.

Fig. 6 is a schematic diagram of the vertical air conditioner indoor unit shown in Fig. 2 when the second air outlet 22 is closed.

The second air outlet 22 can be closed by using the second air guiding component 26 . As shown in FIG. 6 , the second air guide member 26 is rotated to a position where the first plate body 261 closes the second air outlet 22 , so as to close the second air outlet 22 .

In some alternative embodiments, a conventional rotating wind deflector can also be used to guide the air outlet direction of the second air outlet 22 .

Fig. 7 is a partially cutaway view of the vertical air conditioner indoor unit shown in Fig. 1 in the lower column shell 30, and only the structure below the dotted line is cut away in Fig. 7 .

As shown in FIG. 7 , the vertical air conditioner indoor unit also includes a lower column case 30 . The lower column shell 30 is used to introduce or obtain the aforementioned non-heat exchange airflow, and then discharge the non-heat exchange airflow to the second column shell 20 . The first column case 10 and the second column case 20 extend upward from the top end of the lower column case 30 . The first column case 10 and the lower column case 30 can be integrally formed as an integral part, and the second column case 20 and the lower column case 30 can also be integrally formed as an integral part. The lower column shell 30 can constitute the lower casing of the vertical air conditioner indoor unit. When the vertical air conditioner indoor unit is floor-standing, the bottom of the lower column shell 30 is placed on the ground. In the embodiment of the utility model, the lower column shell 30 is used to support and fix the first column shell 10 and the second column shell 20, so that the overall structure of the vertical air conditioner indoor unit is more stable.

In addition, as shown in FIG. 1 , the vertical air conditioner indoor unit may further include an upper connecting shell 40 , and the top ends of the first column shell 10 and the second column shell 20 are both connected to the upper connecting shell 40 . The first column case 10 and the upper connection case 40 can be integrally formed as an integral part, and the second column case 20 and the upper connection case 40 can also be formed as an integral part. By providing the upper connecting shell 40, the structure of the indoor unit of the vertical air conditioner is more stable and the appearance is more coordinated.

A heat exchanger 17 and a first blower 14 are arranged inside the first column shell 10 for producing heat exchange airflow. More specifically, an air inlet 11 may be provided on the rear side or lateral sides of the first column housing 10, and a first air channel 15 is provided in the first column housing 10, and the first air channel 15 communicates with the first air outlet 12. A fan 14 is a cross-flow fan, which is arranged at the entrance of the first air duct 15 . Under the action of the first fan 14, the indoor air enters the first column shell 10 through the air inlet 11, exchanges heat with the heat exchanger 17 to form a heat exchange air flow, and then enters the first air duct 15, and the first air duct 15 Guide to the first air outlet 12, as shown in Figure 2.

As shown in FIG. 7 , a lower blower fan 35 is disposed in the lower column housing 30 for delivering the non-heat exchange airflow to the second column housing 20 . In this way, a fan can be avoided in the second column casing 20 , so that the second column casing 20 can be designed to be thinner, and the space of the lower column casing 30 can be more fully utilized.

FIG. 8 is a left side view of the vertical air conditioner indoor unit shown in FIG. 1 when the lower column housing 30 and the second column housing 20 are partly cut away. There are three curved dashed lines in Figure 8, the area between the two curves at the upper and middle positions is the cutting area, and the area below the lowermost dotted line is the cutting area.

As shown in FIG. 7 and FIG. 8 , the lower fan 35 may include a wind wheel 351 and a volute 352 , the wind wheel 351 is disposed in the volute 352 , and the volute 352 is used to guide the wind direction. The exhaust side of the volute 352 communicates with the second column casing 20 so as to discharge the non-heat exchange airflow to the second column casing 20 . Moreover, the lower column casing 30 is provided with a fresh air inlet 32 and at least one indoor air inlet 31 , both of which communicate with the suction side of the volute 352 . The fresh air inlet 32 is connected with a fresh air pipe 36 so as to introduce fresh air from the outside. The fresh air inlet 32 is located on the rear wall of the lower column housing 30 , and the number of indoor air inlets 31 is two, which are respectively located on the lateral side walls of the lower column housing 30 . In this embodiment, the lower blower fan 35 can not only inhale fresh air, but also inhale indoor air, so as to achieve the effect of killing two birds with one stone. In addition, a damper can be set at the fresh air inlet 32 or the indoor air inlet 31 to control its opening and closing or opening, thereby adjusting the intake ratio of the fresh air flow and the indoor air.

As shown in FIG. 7 and FIG. 8 , the lower fan 35 may further include a filter 353 disposed in the volute 352 for filtering fresh air and indoor air.

If the aforesaid non-heat exchange airflow is a purified airflow, a humidified airflow or a water washing airflow, a purification module, a humidification module or a water washing module may be provided in the lower column casing 30 .

In some embodiments, as shown in FIG. 8 , the second air outlet 22 is in the shape of a vertical bar. The second column shell 20 is provided with a vertical strip-shaped second air duct 25 communicating with the second air outlet 22, and a plurality of vertically arranged guide vanes 23 are arranged in the second air duct 25, each guide vane 23 extends from front to back, and the rear end is bent downward to form a flow guide bending portion 231 . The non-heat exchange airflow flows from bottom to top, and after encountering each guide vane 23, it is guided by its guide bending portion 231, and gradually changes from upward flow to forward flow. Therefore, the air guide bending portion 231 plays a role in changing the direction of the airflow, so that the airflow turns more gently and the wind loss is smaller. The transition between the guide bending portion 231 and the rest of the guide vane 23 is rounded.

Further, considering that the non-heat-exchange air flow enters the second column housing 20 from the bottom of the second column housing 20 , it may cause the air volume at the middle or upper part of the second air outlet 22 to be relatively small. Therefore, in the embodiment of the present utility model, a plurality of guide vanes 23 arranged vertically are arranged in the second column shell 20, and the distance between the front and rear ends of the guide vanes 23 that are positioned higher is greater, so that the second outlet The air outlets of the tuyere 22 are more evenly distributed everywhere in the vertical direction.

Fig. 9 is a schematic front view of a vertical air conditioner indoor unit according to the second embodiment of the present invention; Fig. 10 is a schematic left view of Fig. 9; Fig. 11 is an enlarged cross-sectional view of M-M in Fig. 9; Fig. 12 is a schematic view of Fig. 9 The vertical air conditioner indoor unit shown is a schematic diagram when both the first air guide part and the second air guide part guide the air forward.

As shown in FIGS. 9 to 12 , the main difference between the second embodiment of the present invention and the first embodiment is that the non-heat exchange air flow includes indoor air. A second air outlet 22 is defined on the front side of the peripheral wall of the second column shell 20 . Other parts of the peripheral wall of the second column shell 20 are provided with a second air inlet 21 open to the indoor environment to introduce indoor air. The second column housing 20 is provided with a second fan 24, and the second fan 24 is used to promote the indoor air in the second column housing 20 to be blown out through the second air outlet 22, and then mixed into the heat exchange air flow blown out by the first air outlet 12 , forming a mixed wind effect.

The second column shell 20 and the first column shell 10 are arranged at intervals along the transverse direction, so that the air-inducing space 13 is formed therebetween. The front and rear of the air-introduction interval 13 are connected to the indoor environment. In this way, when the first air outlet 12 and/or the second air outlet 22 blow out air, the indoor air in the air-inducing compartment 13 is driven to flow forward by means of negative pressure.

When the indoor unit of the vertical air conditioner in the embodiment of the utility model is running, the first column housing 10 and the second column housing 20 can be turned on for air supply alternatively or at the same time. When the first air outlet 12 and/or the second air outlet 22 blow out the air, the indoor air in the air-inducing compartment 13 is driven to flow forward by relying on the effect of negative pressure, forming the air-draining and mixing effect. Compared with the heat exchange airflow, the temperature of the mixed airflow is closer to the room temperature, with higher comfort and softer wind feeling, which also increases the air volume and wind speed, and the air supply distance is longer. As shown in FIGS. 9 to 12 , the second air inlet 22 can pass through the lateral side wall and rear wall of the second column housing 20 away from the first column housing 10 , so that the second air inlet 21 faces backward and away from the lateral direction. The direction of the second column shell 20 is opened to increase the air intake range and increase the intake air volume.

As shown in FIGS. 11 and 12 , the second fan 24 can be a cross-flow fan whose axis is parallel to the length direction of the second column shell 20 . This vertically arranged cross-flow fan is suitable for the second vertical air outlet 22 . For example, the second air outlet 22 may be in the shape of an integral vertical bar extending from top to bottom, or may also be in the shape of an intermittent vertical bar formed by a plurality of sub-air outlets arranged vertically. In order to match with the cross-flow fan and make the operation efficiency of the cross-flow fan higher and the wind resistance smaller, as shown in FIG. The outlet of the air flow channel communicates with the second air outlet 22 , and the second fan 24 is arranged in the second air channel 25 . Of course, the second fan can also be an axial fan or a centrifugal fan, or another type of fan, or a cross-flow fan arranged horizontally on the axis. These fans are widely used in the field of air conditioning, and will not be repeated here.

As shown in Figures 11 to 12, the first column housing 10 is equipped with first air guide components 16 for guiding the first air outlet 12 in the horizontal direction of the wind. The straight-extending wind guide swing vane group is driven by a motor to make each swing vane rotate synchronously to change the wind direction. The second column shell 20 is installed with an air guiding swing vane 27 for guiding the second air outlet 22 in a transverse air outlet direction. In addition, the first air outlet 12 can also be closed by the first air guide member 16 , and the second air outlet 22 can be closed by the air guide swing vane 27 , as shown in FIG. 11 .

Fig. 13 is a schematic front view of the vertical air conditioner indoor unit according to the third embodiment of the present invention; Fig. 14 is a C-C sectional enlarged view of Fig. 13; Fig. 15 is a vertical air conditioner indoor unit shown in Fig. 14 when the damper is closed Schematic diagram after wind separation; FIG. 16 is a schematic diagram of the indoor unit of the vertical air conditioner shown in FIG. 15 after the second column shell is turned laterally outward.

As shown in Figures 13 to 16, compared with the first embodiment, the third embodiment of the utility model has the main improvement point that the vertical air conditioner indoor unit also includes a damper 50, and the damper 50 is configured to controlly adjust the induced wind The flow area of interval 13 makes the flow area larger or smaller. Alternatively, the flow area can also be adjusted to zero, that is, the air-introducing compartment 13 is completely closed. Specifically, the damper 50 may be installed on the lower column case 30 .

After the flow area of the air induction compartment 13 is increased, the mixing amount of indoor air becomes larger, which has a greater influence on the temperature of the heat exchange air flow, even if the temperature of the cold air flow increases more, the temperature of the hot air flow decreases more, making the wind feeling more comfortable. This adjustment can be made when the user places particular emphasis on comfort. After the flow area of the air induction compartment 13 is reduced, the mixing amount of indoor air becomes smaller, and the influence on the temperature of the heat exchange air flow is weakened. This adjustment can be performed when the user wants to be directly blown by cold/hot air to obtain a more intuitive and obvious cooling/heating experience. Of course, it is also possible to completely stop its air-inducing function by closing the air-inducing compartment 13 . In a word, the utility model enables the indoor unit of the vertical air conditioner to have more adjustment modes by making the flow area of the induced air compartment 13 adjustable.

The damper 50 can be configured to be rotatable around the vertical axis x1 to adjust the flow area of the air-inducing compartment 13 . The design of the rotating structure is relatively simple, and it only needs to be directly driven by the motor. Specifically, the damper 50 can be arranged at the entrance of the air-inducing compartment 13, and it is a vertically extending prism, and the surface of its outer peripheral wall part constitutes the wind-shielding surface 51, and the rotation axis x1 of the damper 50 is far away from the wind-shielding surface 51, and Located behind the second column shell 20 . The damper 50 is configured to: be rotatable to a closed position where the wind-inducing compartment 13 is shielded by the windshield surface 51 , as shown in FIG. 15 ; or to be rotatable to a closed position located behind the second column housing 20 . In the open position, as shown in FIG. 14 , the damper 50 is kept away from the air intake path of the air introduction compartment 13 , so that the air intake is smoother. When in the open position, the windshield surface 51 can face away from the direction of the first column case 10 (for example, in FIG. 14, the first column case 10 is located on the right side of the second column case 20, so the windshield surface 51 faces to the right) .

Further, as shown in FIGS. 15 and 16 , the second column housing 20 can be configured to be rotatably mounted on the lower column housing 30 around a vertical axis to adjust the direction of the second air outlet 12 , thereby adjusting the second air outlet. The air outlet direction of the tuyere 12. The vertical air conditioner indoor unit can change the angle between the non-heat exchange air flow and the heat exchange air flow by adjusting the air outlet direction of the second air outlet 12, and then change the intersection position of the two. Specifically, the larger the angle between the heat exchange airflow direction and the heat exchange airflow direction, the closer the intersection position is, that is, the closer to the vertical air conditioner indoor unit; the smaller the angle, the farther the intersection position is, that is, the farther the vertical air conditioner Air conditioner indoor unit. The indoor unit of the vertical air conditioner can adjust the above-mentioned intersection position according to the position of the human body, so as to avoid the intersection position being close to the human body and causing discomfort to the human body. In addition, when it is necessary to mix the outlet airflows of the two column housings, the second column housing 20 can also be configured to move with the action of the first air guide member 16, so as to ensure that the indoor air can be mixed into the heat exchange airflow to avoid The two air streams flow away from each other.

In this embodiment, by making the second column housing 20 rotatable as a whole, there is no need to design an additional air guide structure at the second air outlet 22 , so that the appearance of the second column housing 20 is more concise.
