The non-heat exchange air flow is mixed with the heat exchange air flow 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, humidifying air flow or washing air flow.

Therefore, when the first cylindrical shell and/or the second cylindrical shell are exhausted, a negative pressure environment is formed at the induced air interval, indoor air at the rear of the vertical air conditioner indoor unit is enabled to flow forwards through the induced air interval so as to be mixed into the air outlet flow of the first cylindrical shell or the second cylindrical shell, the mixing amount of the indoor air is larger, the mixing speed is higher, and a stronger air mixing effect is formed. In addition, the indoor refrigerating/heating speed is increased, the energy efficiency of the air conditioner is improved, and the effects of energy conservation and emission reduction are achieved.

Furthermore, the invention enables the flow area of the induced air interval to be adjustable by arranging the air door, thereby being convenient for adjusting the mixing amount of indoor air and adjusting the air outlet temperature. Of course, when the user selects to adjust the flow area of the induced air interval to zero, that is, to close the induced air interval, the induced air function of the induced air interval may be closed.

Furthermore, in the indoor unit of the vertical air conditioner, the second cylindrical shell can be rotatably arranged on the lower cylindrical shell around the vertical axis, so that the orientation of the second air outlet can be adjusted. And moreover, the included angle between the non-heat-exchange air flow and the heat-exchange air flow can be adjusted according to the adjustment, and the intersection position of the non-heat-exchange air flow and the heat-exchange air flow is further changed. Moreover, the second column shell can be integrally rotated, and a wind guide structure is not required to be designed at the second air outlet, so that the appearance of the second column shell is simpler.

The invention provides a vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner is an indoor part of a split type air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like. The vertical air conditioner indoor machine can be a conventional floor type cabinet machine or a vertical wall-mounted machine.

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

As shown in fig. 1 and 2, the indoor unit of an upright air conditioner according to the first embodiment of the present invention may generally include a first cylindrical case 10 and a second cylindrical case 20.

The first cylindrical shell 10 is in a vertical cylindrical shape, that is, a hollow cylindrical shell. The first cylindrical shell 10 is provided with a first air outlet 12 for blowing out heat exchange air flow. The "heat exchange airflow" refers to airflow that exchanges heat with the heat exchanger 17 of the air conditioner and is used for adjusting the indoor temperature. The heat exchanger 17 is connected with a compressor, a heat exchanger of an outdoor unit, a throttling device and other refrigeration elements through pipelines to form a vapor compression refrigeration cycle system. When the vertical air conditioner indoor unit is in a refrigeration mode, the heat exchange airflow is cold air; when the vertical air conditioner indoor unit is in a heating mode, the heat exchange air flow is hot air. The heat transfer gas flows through the first air outlet 12 and is blown to the indoor environment, thereby completing the refrigeration and heating of the indoor environment.

The second cylindrical shell 20 is in a vertical cylindrical shape, that is, a hollow cylindrical shell. The second cylindrical shell 20 is provided with a second air outlet 22 for blowing out non-heat-exchange airflow. Specifically, the non-heat exchange air flow may be one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow, and is used for auxiliary regulation of indoor environment.

In the field of air conditioning, some double-column vertical air conditioning indoor units exist, but two column shells of the air conditioning indoor units are used for blowing heat exchange air flows, and the form is very single. The vertical air-conditioning indoor unit of the embodiment of the invention designs the second cylindrical shell 20 which is parallel to the first cylindrical shell 10 and is specially used for blowing out non-heat-exchange airflow, and the structure breaks through the conventional structure and is very novel and ingenious. In addition, because the heat exchanger does not need to be arranged in the second cylindrical shell 20, the second cylindrical shell 20 can be designed to be thinner, so that the second cylindrical shell is obviously thinner than the first cylindrical shell 10, the asymmetric design not only meets the requirement of mixed air, but also enables the appearance of the vertical air conditioner indoor unit to be more novel and unique, and the competitiveness of the product in the aspect of appearance is improved.

As shown in fig. 1 and 2, the first outlet 12 is opened at the front side of the first casing 10, and the second outlet 22 is opened at the front side of the second casing 20, so as to allow the non-heat-exchange airflow to mix with the heat-exchange airflow in front of the indoor unit of the vertical air conditioner.

The existing vertical air conditioner indoor unit has the defects of unobvious appearance difference and poor air supply experience, so that users have many complaints. Particularly, when an air conditioner is used for refrigeration, the air outlet temperature is often low, the air speed is high, and cold air directly blows to a human body to cause discomfort, that is, the wind is hard and not soft enough.

In the embodiment of the invention, the vertical air-conditioning indoor unit blows out heat exchange airflow by using the first cylindrical shell 10 and blows out non-heat exchange airflow by using the second cylindrical shell 20, and the non-heat exchange airflow is mixed with the heat exchange airflow in front of the vertical air-conditioning indoor unit. When the non-heat exchange air flow is indoor air, the non-heat exchange air flow is mixed with the heat exchange air flow to form mixed air flow, the temperature of the mixed air flow is closer to room temperature than that of the heat exchange air flow, the comfort is higher, the wind feeling is softer, the wind quantity and the wind speed are increased, and the wind supply distance is farther. When the second cylindrical shell 20 blows out conditioning air flows such as fresh air flow, purified air flow, humidifying air flow or washing air flow, the conditioning air flows can be mixed with the heat exchange air flow more early and more, the mixing rate is enhanced, and the conditioning air flows can be better diffused to all places indoors.

Further, as shown in fig. 2, the second column casing 20 and the first column casing 10 may be arranged in the transverse direction, and an air inducing space 13 may be formed therebetween. The front and rear of the induced air interval 13 are communicated with the indoor environment. The "lateral direction" is indicated in the drawings, and the left-right direction perpendicular to the front-rear direction of the indoor unit of the floor air conditioner is the "lateral direction".

When the vertical air conditioner indoor unit of the embodiment of the invention operates, the first cylindrical shell 10 and the second cylindrical shell 20 can be opened for air supply alternatively or simultaneously. When the air flows out of the first air outlet 12 and/or the second air outlet 22, the indoor air in the induced air interval 13 is driven to flow forward by virtue of the negative pressure effect, so that the indoor air behind the vertical air conditioner indoor unit flows forward through the induced air interval 13 to be mixed with the air outlet flow of the first cylindrical shell 10 or the second cylindrical shell 20, and a flow-guiding and air-mixing effect is formed. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. Particularly, when the second cylinder case 20 also blows out the room air, the mixing amount of the room air is larger, the mixing speed is faster, a stronger air mixing effect can be achieved, and the airflow is closer to the room temperature.

As shown in fig. 2, the ratio of the width of the second column housing 20 in the lateral direction to the width of the first column housing 10 in the lateral direction may be made smaller than 1/2. The width refers to a distance between two points at which the outer wall of the second cylindrical shell 20 or the first cylindrical shell 10 is farthest in the lateral direction on both lateral sides. The ratio of the depth dimension of the second column casing 20 in the front-rear direction to the depth dimension of the first column casing 10 in the front-rear direction is less than 1/2, which means the distance between two points at which the front and rear outer walls of the second column casing 20 or the first column casing 10 are farthest in the front-rear direction. Thus, the size difference between the two is large enough to form a double-column differentiated appearance. The second outlet 22 can be flush or substantially flush with the front and back of the first outlet 12, for example, the distance between the front and back is not more than 5cm, so that the non-heat exchange air flow and the heat exchange air flow are mixed better.

As shown in fig. 2, a second air duct 25 communicated with the second air outlet 22 is disposed in the second cylindrical shell 20, so that the non-heat-exchange airflow in the second cylindrical shell 20 is guided to the second air outlet 22 more smoothly. The distance between the two lateral side walls 251, 252 of the second air duct 25 gradually decreases from back to front, forming a taper. The tapered air duct can accelerate air flow, so that non-heat-exchange air flow can be blown out of the second air outlet 22 more quickly, and negative effects on wind speed caused by the fact that no fan is arranged in the second cylinder shell 20 can be compensated to a certain extent.

As shown in fig. 2, the air inducing space 13 may be a gradually expanding shape whose lateral dimension gradually increases from back to front, so that the outlet airflows of the first outlet 12 and the second outlet 22 can better form negative pressure at the outlet area of the air inducing space 13, so that the airflow volume of the air inducing space 13 is larger.

Fig. 3 is an enlarged view of fig. 2 at a, fig. 4 is a schematic view of the indoor stand air conditioner shown in fig. 2 when switched to the left air blowing mode, and fig. 5 is a schematic view of the indoor stand air conditioner shown in fig. 2 when switched to the right air blowing mode.

As shown in fig. 2 to 5, a second wind guide member 26 for guiding the second wind outlet 22 in the transverse wind outlet direction is mounted on the second column casing 20. "directing the lateral wind direction" refers to changing the angle between the wind direction and the front-back direction, for example, blowing the wind forward right, forward left, forward right, and so on. In addition, a first air guiding component 16 for guiding the transverse air outlet direction of the first air outlet 12 is mounted on the first cylindrical shell 10.

The vertical air conditioner indoor unit can change the included angle between the non-heat exchange air flow and the heat exchange air flow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, and further change the intersection position of the non-heat exchange air flow and the heat exchange air flow. Specifically, the larger the included angle between the wind direction of the heat exchange airflow and the wind direction of the heat exchange airflow is, the closer the intersection position is, that is, the closer to the indoor unit of the vertical air conditioner is; the smaller the included angle is, the farther the intersection position is, namely, the farther away the vertical air conditioner indoor unit is. The vertical air-conditioning indoor unit can adjust the intersection position according to the position of a human body so as to avoid the intersection position from approaching the human body and bringing discomfort to the human body.

In addition, the indoor unit of the floor air conditioner may be further configured to: the second air guiding part 26 is used for adjusting the transverse air outlet direction of the second air outlet 22, so that the non-heat exchange air flow can be converged into the heat exchange air flow of the first air outlet 12. That is, after the first air guiding component 16 changes the air outlet direction of the heat exchange airflow, the second air guiding component 26 is controlled to operate, so as to ensure that the non-heat exchange airflow can always converge into the heat exchange airflow. For example, as shown in fig. 2, when the first air guiding member 16 swings forward, the second air guiding member 26 guides the air forward. As shown in fig. 4, when the first air guiding member 16 swings left, the second air guiding member 26 guides left air. As shown in fig. 5, when the first air guiding member 16 swings right, the second air guiding member 26 guides the air to the right. The main control board of the air conditioner can be electrically connected with the motors of the second air guiding part 26 and the first air guiding part 16 at the same time so as to control the two parts to act cooperatively.

As shown in fig. 3, the second air guiding component 26 may include a first plate 261 and a second plate 262 which are arranged at a distance in the lateral direction. Of course, the second plate 262 is connected to the first plate 261 by other structures, which are not shown in fig. 3. The end of the first plate 261 close to the second plate 262 has a bent portion 2611 that bends backwards, and an air guiding channel 260 that is gradually narrowed from back to front is formed between the bent portion 2611 and the second plate 262. The second wind guiding component 26 is rotatably mounted on the second column casing 20 around the vertical axis x, so as to change the transverse wind outlet direction of the second wind outlet 22 by adjusting the relative position of the wind guiding channel 260 and the second wind outlet 22.

For example, as shown in fig. 2 and 3, when the air guiding channel 260 faces the second air outlet 22, the non-heat-exchange air flow is guided to be blown out towards the front. As shown in fig. 4, the second air guiding member 26 is rotated clockwise with respect to the state of fig. 2, so that the air guiding passage 260 is directed to the front left, and the non-heat-exchanged air flow is guided to be blown out to the front left. As shown in fig. 5, the second air guiding part 26 is rotated counterclockwise relative to the state of fig. 2, so that the air guiding channel 260 is directed to the front right, so as to guide the non-heat-exchange air flow to be blown out to the front right. The air guide piece of the embodiment has a very simple structure, occupies a small space, is particularly suitable for the narrow air outlet of the second air outlet 22, and is skillfully designed.

As shown in fig. 3, a second air duct 25 communicating with the second air outlet 22 may be disposed in the second cylindrical shell 20. One lateral side wall 251 of the second air duct 25 defines a receiving groove 2512, and the other lateral side wall 252 defines a recess 2523. When the second air guiding component 26 rotates to a transverse limit angle, the first plate 261 is extended into the receiving groove 2512, so that the air guiding surface of the bending portion 2611 is flush with the surface of the transverse side wall 251 of the second air duct 25, as shown in fig. 4, so that the air flow can enter the air guiding channel 260 more smoothly from the second air duct 25. Similarly, when the second air guiding component 26 rotates to another lateral limit angle, the second plate 262 is inserted into the recess 2523, so that the air guiding surface of the second plate 262 is flush with the surface of the lateral sidewall 252 of the second air duct 25, as shown in fig. 5.

Fig. 6 is a schematic view of the indoor stand air-conditioner shown in fig. 2 when the second outlet 22 is closed.

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

In some alternative embodiments, a conventional rotating air deflector may also be used to direct the air exiting from the second outlet 22.

Fig. 7 is a partially cut-away view of the bottom casing 30 of the indoor unit of the air conditioning stand shown in fig. 1, and only the structure below the broken line in fig. 7 is cut away.

As shown in fig. 7, the indoor unit of a vertical air conditioner further includes a lower column casing 30. The lower shell 30 is adapted to introduce or produce the aforementioned non-heat exchange gas stream and then to discharge the non-heat exchange gas stream toward the second shell 20. The first and second column housings 10 and 20 extend upward from the top end of the lower column housing 30. The first column shell 10 and the lower column shell 30 may be formed as an integral piece, or the second column shell 20 and the lower column shell 30 may be formed as an integral piece. The lower cylindrical casing 30 can be made to constitute a lower casing of the indoor unit of a floor type air conditioner, and when the indoor unit of a floor type air conditioner is a floor type air conditioner, the bottom of the lower cylindrical casing 30 is placed on the ground. In the embodiment of the invention, the lower cylindrical shell 30 is used for supporting and fixing the first cylindrical shell 10 and the second cylindrical shell 20, so that the integral structure of the vertical air-conditioning indoor unit is firmer.

In addition, as shown in fig. 1, the vertical air conditioning indoor unit may further include an upper connection case 40, and the top ends of the first and second column cases 10 and 20 are both connected to the upper connection case 40. The first cylindrical shell 10 and the upper connecting shell 40 may be formed as an integral piece, or the second cylindrical shell 20 and the upper connecting shell 40 may be formed as an integral piece. By arranging the upper connecting shell 40, the structure of the vertical air conditioner indoor unit is more stable, and the appearance is more harmonious.

A heat exchanger 17 and a first fan 14 are arranged in the first column shell 10 for generating a heat exchange air flow. More specifically, the rear side or the two lateral sides of the first cylindrical shell 10 may be provided with an air inlet 11, a first air duct 15 is provided in the first cylindrical shell 10, the first air duct 15 is communicated with the first air outlet 12, and the first fan 14 is a cross-flow fan and is disposed at an inlet of the first air duct 15. Under the action of the first fan 14, indoor airflow enters the first cylindrical shell 10 through the air inlet 11, exchanges heat with the heat exchanger 17 to form heat exchange airflow, then enters the first air duct 15, and is guided to the first air outlet 12 through the first air duct 15, as shown in fig. 2.

As shown in fig. 7, a lower fan 35 is provided in the lower column casing 30 for feeding the non-heat-exchange air flow to the second column casing 20. Thus, the fan can be prevented from being provided in the second cylindrical shell 20, so that the second cylindrical shell 20 can be designed to be thinner, and the space of the lower cylindrical shell 30 can be more fully utilized.

Fig. 8 is a left side view of the indoor unit of an upright air conditioner shown in fig. 1, in which portions of the lower cylindrical casing 30 and the second cylindrical casing 20 are cut away. In fig. 8, there are 3 curved dotted lines in total, and the area between the two curves at the upper and middle positions is a cut area, and the area below the dotted line at the lowermost position is a cut area.

As shown in fig. 7 and 8, the lower fan 35 may include a wind wheel 351 and a scroll 352, the wind wheel 351 being disposed within the scroll 352, the scroll 352 serving to guide a wind direction. The exhaust side of the volute 352 communicates with the second column housing 20 to discharge the non-heat exchange gas stream toward the second column housing 20. In addition, the lower column casing 30 is provided with a fresh air inlet 32 and at least one indoor air inlet 31 both communicating with the suction side of the scroll 352. The fresh air inlet 32 is connected with a fresh air pipe 36 so as to introduce fresh air flow from the outside. The fresh air inlets 32 are located on the rear wall of the lower cylindrical shell 30, and the number of the indoor air inlets 31 is two, and the two indoor air inlets are respectively located on two lateral walls of the lower cylindrical shell 30. This embodiment makes down fan 35 can inhale new trend air current, can inhale indoor air again, reaches the effect of killing two birds with one stone. In addition, an air door can be arranged at the fresh air inlet 32 or the indoor air inlet 31 to control the opening and closing or the opening degree of the fresh air inlet or the indoor air inlet, so that the air inlet ratio of fresh air flow to indoor air is adjusted.

As shown in fig. 7 and 8, the lower fan 35 may further include a filter screen 353 disposed within the scroll 352 for filtering the fresh airflow and the indoor air.

If the non-heat exchange air flow is a purified air flow, a humidified air flow or a water washing air flow, a purification module, a humidified module or a water washing module may be disposed in the lower column housing 30.

In some embodiments, as shown in fig. 8, the second outlet 22 is vertical. A second air duct 25 in a vertical bar shape is arranged in the second cylindrical shell 20 and communicated with the second air outlet 22, a plurality of guide vanes 23 arranged vertically are arranged in the second air duct 25, each guide vane 23 extends from front to back, and the rear end of each guide vane is bent downwards to form a guide bending part 231. The non-heat-exchange air flow flows from bottom to top, and after meeting each guide vane 23, the non-heat-exchange air flow is guided by the guide bending part 231 thereof, and gradually changes from top to front. Therefore, the diversion bending part 231 plays a role in changing the direction of the airflow, so that the turning of the airflow is smoother, and the wind loss is smaller. The diversion bent part 231 is in round transition with the rest of the diversion sheet 23.

Further, considering that the non-heat-exchange airflow enters the second column casing 20 from the bottom of the second column casing 20, the air outlet amount at the middle or upper part of the second air outlet 22 may be smaller. Therefore, in the embodiment of the present invention, especially, the plurality of flow deflectors 23 vertically arranged are disposed in the second column shell 20, and the distance between the front end and the rear end of the flow deflector 23 located above the second column shell is larger, so that the air outlet of the second air outlet 22 at each vertical position is more uniform.

Fig. 9 is a schematic front view of a vertical air conditioner indoor unit according to a second embodiment of the present invention; FIG. 10 is a schematic left side view of FIG. 9; FIG. 11 is an enlarged cross-sectional view M-M of FIG. 9; fig. 12 is a schematic view of the floor air conditioning indoor unit shown in fig. 9, when both the first air guide member and the second air guide member are facing the front air guide.

As shown in fig. 9 to 12, the second embodiment of the present invention is different from the first embodiment mainly in that the non-heat-exchange air stream includes indoor air. A second air outlet 22 is opened on the front side of the peripheral wall of the second cylindrical shell 20. The second cylinder 20 has a second air inlet 21 opened to the indoor environment at other portions of the circumferential wall thereof to introduce indoor air. The second fan 24 is disposed in the second casing 20, and the second fan 24 is configured to cause the indoor air in the second casing 20 to be blown out through the second air outlet 22 and then mixed with the heat exchange airflow blown out by the first air outlet 12, so as to form an air mixing effect.

The second cylindrical shell 20 and the first cylindrical shell 10 are arranged at a spacing in the transverse direction so as to form an induced draft space 13 therebetween. The front and rear of the induced draft space 13 are both communicated with the indoor environment. Therefore, when the air is discharged from the first air outlet 12 and/or the second air outlet 22, the indoor air in the air inducing interval 13 is driven to flow forwards under the action of negative pressure.

When the vertical air conditioner indoor unit of the embodiment of the invention operates, the first cylindrical shell 10 and the second cylindrical shell 20 can be opened for air supply alternatively or simultaneously. When the first air outlet 12 and/or the second air outlet 22 are/is exhausted, the indoor air in the induced draft interval 13 is driven to flow forward under the action of negative pressure, and a flow-guiding and air-mixing effect is formed. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. As shown in fig. 9 to 12, the second air inlet 22 may penetrate through the lateral side wall and the rear wall of the second cylindrical shell 20 away from the first cylindrical shell 10, so that the second air inlet 21 opens rearward and laterally away from the second cylindrical shell 20, thereby increasing the air inlet range and increasing the air inlet amount.

As shown in fig. 11 and 12, the second fan 24 may be a cross-flow fan having an axis parallel to the longitudinal direction of the second casing 20. The cross-flow fan arranged vertically is suitable for the second air outlet 22 in the shape of a vertical bar. For example, the second outlet 22 may be an integral vertical bar extending from top to bottom, or an intermittent vertical bar formed by a plurality of vertically arranged sub-outlets. In order to match with the cross-flow fan, the operation efficiency of the cross-flow fan is higher, and the wind resistance is smaller, as shown in fig. 11, a second air duct 25 may be formed in the second cylindrical housing 20, the second air duct 25 is a cross-flow air duct, an outlet of the second air duct is communicated with the second air outlet 22, and the second fan 24 is disposed in the second air duct 25. Of course, the second fan may also be an axial flow fan or a centrifugal fan, or a fan of other form, or a cross-flow fan with its axis horizontally disposed, and these fans are widely used in the air conditioning field and are not described herein again.

As shown in fig. 11 to 12, a first air guiding component 16 for guiding the first air outlet 12 in the transverse air outlet direction is mounted on the first cylindrical shell 10, specifically, the first air guiding component 16 may respectively include an air guiding vane set with an axis extending vertically, and each vane is driven by a motor to synchronously swing and rotate so as to change the wind direction. The second cylindrical shell 20 is provided with an air guide swing blade 27 for guiding the second air outlet 22 in the transverse air outlet direction. In addition, the first air guiding part 16 can be used for closing the first air outlet 12, and the air guiding swing blade 27 can be used for closing the second air outlet 22, as shown in fig. 11.

Fig. 13 is a schematic front view of a floor air conditioning indoor unit according to a third embodiment of the present invention; FIG. 14 is an enlarged cross-sectional view C-C of FIG. 13; fig. 15 is a schematic view of the indoor unit of the stand type air conditioner of fig. 14 after the air door is closed for an induced air interval; fig. 16 is a schematic view of the indoor unit of a stand type air conditioner shown in fig. 15 after the second column casing has been rotated outward in the lateral direction.

As shown in fig. 13 to 16, the third embodiment of the present invention is mainly improved over the first embodiment in that the vertical air conditioning indoor unit further includes a damper 50, and the damper 50 is configured to controllably adjust the flow area of the induced air space 13 to increase or decrease the flow area. Alternatively, the flow area can also be set to zero, i.e. the wind gap 13 is completely closed. Specifically, the damper 50 may be mounted on the lower column case 30.

After the flow area of the induced air interval 13 is increased, the mixing amount of indoor air is increased, the temperature influence on the hot air exchanging flow is larger, namely, the temperature of the cold air flow is increased more, the temperature of the hot air flow is reduced more, and the wind sensation is more comfortable. This adjustment can be made when the user is particularly concerned about comfort. When the flow area of the induced air space 13 is reduced, the amount of the mixed indoor air is reduced, and the influence on the temperature of the heat exchange airflow is weakened. The user can make this adjustment when he wants to be directly blown by cold/hot air to obtain a more intuitive and obvious cooling/heating feeling. It is of course also possible to stop its draught function completely by closing the draught space 13. In a word, the invention enables the vertical air conditioner indoor unit to have more adjusting modes by enabling the flow area of the air inducing interval 13 to be adjustable.

The damper 50 may be configured to rotatably adjust the flow area of the induced air space 13 about the vertical axis x 1. The design of the rotating structure is simple, and the rotating structure can be directly driven by only a motor. Specifically, the damper 50 may be provided at the entrance of the induced air space 13, and may have a vertically extending prism shape, an outer peripheral wall portion surface of which constitutes the wind shielding surface 51, and the rotation axis x1 of the damper 50 is away from the wind shielding surface 51 and located rearward of the second column housing 20. The damper 50 is configured to: can be rotated to a closed position in which the wind-guiding space 13 is shielded by the wind-shielding surface 51, as shown in fig. 15; or to a closed position behind the second housing 20. In the open position, as shown in fig. 14, this positions the damper 50 away from the air intake path of the induced air space 13, making the intake of air smoother. In the open position, the wind shielding surface 51 may be directed away from the first column housing 10 (for example, in fig. 14, the first column housing 10 is located on the right side of the second column housing 20, and the wind shielding surface 51 is directed to the right).

Further, as shown in fig. 15 and 16, the second cylindrical housing 20 may be configured to be rotatably mounted to the lower cylindrical housing 30 about a vertical axis to adjust the orientation of the second air outlet 12, thereby adjusting the air outlet direction of the second air outlet 12. The vertical air conditioner indoor unit can change the included 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 further change the intersection position of the non-heat exchange air flow and the heat exchange air flow. Specifically, the larger the included angle between the wind direction of the heat exchange airflow and the wind direction of the heat exchange airflow is, the closer the intersection position is, that is, the closer to the indoor unit of the vertical air conditioner is; the smaller the included angle is, the farther the intersection position is, namely, the farther away the vertical air conditioner indoor unit is. The vertical air-conditioning indoor unit can adjust the intersection position according to the position of a human body so as to avoid the intersection position from approaching the human body and bringing discomfort to the human body. In addition, when the outlet air flows of the two column casings need to be mixed with each other, the second column casing 20 may be configured to operate in accordance with the operation of the first air guiding member 16, so as to ensure that the indoor air can be mixed into the heat exchange air flow, and to prevent the two air flows from flowing away from each other.

This embodiment is through making the whole rotatable of second shell 20, need not to design extra wind-guiding structure again in second air outlet 22 department, makes second shell 20's outward appearance more succinct.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
