Optionally, a second air duct connected to the second air outlet is provided in the second column shell; the distance between the two transverse side walls of the second air duct gradually becomes smaller from back to front, forming a tapering. shape.

The vertical air conditioner indoor unit of the present invention uses the first column shell to blow out the heat exchange air flow, and uses the second column shell to blow out the non-heat exchange air flow. An air induction interval is formed between the first column shell and the second column shell. In this way, when the first column shell and/or the second column shell blow out the air, a negative pressure environment is formed at the air induction interval, which prompts the indoor air behind the vertical air conditioner indoor unit to flow forward through the air induction interval to be mixed into the first The outlet airflow of the column shell or the second column shell forms a diversion and air mixing effect. Compared with the heat exchange air flow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is farther. Moreover, the non-heat exchange air flow of the second column shell can also be mixed into the heat exchange air flow. When the second column shell blows out indoor air, a stronger air mixing effect can be achieved, making the air flow closer to room temperature. When the second column shell blows out fresh air flow and purifies When the air flow, humidified air flow or water washing air flow is adjusted, these adjusted air flows can be mixed with the heat exchange air flow earlier and more, enhancing the mixing rate and making it better spread throughout the room. 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.

In addition, the present invention makes it possible to adjust the flow area of the air induction interval by setting a damper, thereby facilitating the adjustment of the mixing amount of indoor air and thus the outlet air temperature. Of course, when the user chooses to adjust the flow area of the draft interval to zero, that is, when the draft interval is turned off, the draft function of the draft interval can be turned off.

Further, in the vertical air conditioner indoor unit of the present invention, the second column housing is rotatably installed on the lower column housing around the vertical axis, so that the direction of the second air outlet is adjustable. Moreover, the 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 guide structure at the second air outlet, making the appearance of the second column housing simpler.

Furthermore, considering that the non-heat exchange airflow enters the second column shell from the bottom of the second column shell, the air outlet volume in the middle or upper part of the second air outlet may be small. Therefore, the present invention specifically arranges a plurality of vertically arranged air guide fins in the second column shell, and the distance between the front and rear ends of the air guide fins that are located higher up is larger, so that the second air outlet is in the vertical direction. The air outflow is more even everywhere.

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

Fig. 1 is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention; Fig. 2 is an enlarged view of the N-N cross-section of Fig. 1; Fig. 3 is a diagram of the vertical air conditioner indoor unit shown in Fig. 2 when the damper is closed and the air induction interval is Schematic diagram after. Figures 2 and 3 use solid arrows to indicate the flow direction of the heat exchange air flow, and hollow arrows to indicate the flow direction of the non-heat exchange air flow.

As shown in FIGS. 1 to 3 , the vertical air conditioner indoor unit according to the embodiment of the present invention may generally include a first column housing 10 , a second column housing 20 and a damper 50 .

The first column shell 10 is in the shape of a vertical column, that is, a hollow columnar shell. A first air outlet 12 for blowing out heat exchange airflow is provided on the front side of the first column shell 10 . 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. Heat exchanger 17 and compressor, The heat exchanger, throttling device and other refrigeration components of the outdoor unit are connected 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 air flow is cold air; when the indoor unit of the vertical air conditioner is in the heating mode, the heat exchange air flow is hot air. The heat exchange air flows through the first air outlet 12 and is blown to the indoor environment to complete the cooling and heating of the indoor environment.

The second column shell 20 is in the shape of a vertical column, that is, a hollow columnar shell. A second air outlet 22 for blowing out non-heat exchange airflow is provided on the front side of the second column housing 20 . 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 function is to assist in regulating the indoor environment. Moreover, the second column shell 20 and the first column shell 10 are arranged in a transverse direction, and an air induction interval 13 is formed between them. The front and rear sides of the air induction interval 13 are connected to the indoor environment. The "horizontal" direction is marked in the figure, and the left and right directions perpendicular to the front and rear directions of the vertical air conditioner indoor unit are the "horizontal directions". When the vertical air conditioner indoor unit is running, the first column housing 10 and the second column housing 20 can be selectively turned on or the air supply can be started at the same time. When the first air outlet 12 and/or the second air outlet 22 discharges air, the negative pressure is used to drive the indoor air in the air induction interval 13 to flow forward to mix with the air outlet from the first column shell 10 or the second column shell 20 flow, forming the effect of diversion and mixed wind. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, and the comfort is higher, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is farther.

The first air outlet 12 and the second air outlet 22 can be in the shape of an integral vertical strip extending from top to bottom, or they can also be in the shape of an intermittent vertical strip composed of a plurality of vertically arranged sub-air outlets, so as to fully utilize the first air outlet 12 and the second air outlet 22 . The height space of the first column shell 10 and the second column shell 20.

The damper 50 is configured to controllably adjust the flow area of the air induction interval 13 to increase or decrease the flow area. Alternatively, the flow area can also be adjusted to zero, that is, the air induction interval 13 can be completely closed.

After the flow area of the induced draft interval 13 increases, the mixing amount of indoor air becomes larger, which has a greater impact on the temperature of the heat exchange air flow. That is, the temperature of the cold air flow increases more, and the temperature of the hot air flow decreases more, making the wind feel More comfortable. This adjustment can be made when the user pays special attention to comfort. After the flow area of the air induction interval 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. Users can make this adjustment when they want to be blown directly by cold/hot air to obtain a more intuitive and obvious cooling/heating experience. Of course, the air inducing function can also be completely stopped by closing the air inducing interval 13 . In short, the present invention allows the vertical air conditioner indoor unit to have more adjustment modes by making the flow area of the air induction interval 13 adjustable.

In some embodiments, the vertical air conditioner indoor unit is configured to have an operating mode in which the heat exchange airflow blown out of the first air outlet 12 and the non-heat exchange airflow blown out of the second air outlet 22 are mixed in front of the vertical air conditioner indoor unit. Specifically, the normal directions of the first air outlet 12 and the second air outlet 22 can be sandwiched. Maintain an angle greater than 0 so that the two outlet airflows can mix. Of course, the air is also guided through the air guide structure so that the two outlet airflows can be mixed. In this way, when the second column shell 20 also blows out the indoor air, the mixing amount of indoor air is larger and the mixing speed is faster, which can achieve a stronger air mixing effect and make the air flow closer to room temperature. 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 air flows, these regulated air flows can be mixed with the heat exchange air flow earlier and more, thereby enhancing the mixing rate and making it more efficient. Spreads well throughout the room.

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 to be thinner, making it significantly thinner than the first column shell 10. This asymmetric design just meets the requirement of mixed air. needs, and makes the appearance of the vertical air conditioner indoor unit more novel and unique, improving the competitiveness of the product. For example, the ratio of the width of the second column shell 20 in the transverse direction to the width of the first column shell 10 in the transverse direction can be less than 1/2. The width refers to the distance between the two farthest points of the outer walls on both sides of the second column shell 20 or the first column shell 10 in the transverse direction. The ratio of the depth dimension of the second cylindrical shell 20 along the front-rear direction to the depth dimension of the first cylindrical shell 10 along the front-rear direction is less than 1/2. This dimension refers to the front and rear sides of the second cylindrical shell 20 or the first cylindrical shell 10. The distance between the two furthest points on the outer wall in the front-to-back direction. This makes the size difference between the two large enough to form a differentiated appearance of the two 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 front and rear distance between them does not exceed 5 cm, so that the non-heat exchange air flow and the heat exchange air flow can be better mixed.

In some embodiments, as shown in FIGS. 2 and 3 , the damper 50 can be configured to rotatably adjust the flow area of the air induction interval 13 around the vertical axis x1. The design of the rotating structure is relatively simple and only needs to be directly driven by the motor.

Specifically, the damper 50 can be disposed at the entrance of the air induction compartment 13 and be in the shape of a vertically extending prism, with part of its outer peripheral wall surface forming the windshield 51, and the rotation axis x1 of the damper 50 being away from the windshield 51, and Located behind the second column housing 20 . The damper 50 is configured to: rotate to a closed position in which the wind shielding surface 51 blocks the air induction interval 13 , as shown in FIG. 3 ; or rotate to a closed position located behind the second column housing 20 . In the open position, as shown in Figure 2, the damper 50 is kept away from the air inlet path of the air induction interval 13, making the air inlet smoother. In the open position, the windshield 51 can be directed away from the first column shell 10 (for example, in Figure 2, if the first column shell 10 is located on the right side of the second column shell 20, the windshield 51 can be directed to the right) .

In some embodiments, as shown in FIGS. 1 to 3 , the vertical air conditioner indoor unit further includes a lower column housing 30 . The first column housing 10 and the second column housing 20 extend upward from the top of the lower column housing 30 . The damper 50 is installed on the lower column housing 30 . The first column shell 10 and the lower column shell 30 can be made into an integral part, or they can be The second column housing 20 and the lower column housing 30 are integrally formed. 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 present invention, the lower column shell 30 is used to support and fix the first column shell 10 and the second column shell 20, making the overall structure of the vertical air conditioner indoor unit more stable.

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

Figure 4 is a schematic diagram of the vertical air conditioner indoor unit shown in Figure 3 after the second column housing 20 is rotated laterally outward;

In some embodiments, as shown in FIGS. 3 and 4 , the second column housing 20 can be configured to be rotatably mounted on the lower column 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 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, thereby changing the intersection position of the two. Specifically, the larger the angle between the wind direction of the heat exchange air flow and the wind direction of the heat exchange air flow, the closer the intersection position is, that is, closer to the vertical air conditioner indoor unit; the smaller the angle is, the farther the intersection position is, that is, the farther away from the vertical air conditioner indoor unit. Air conditioning indoor unit. The vertical air conditioner indoor unit can adjust the aforementioned intersection position according to the position of the human body to avoid the intersection position being close to the human body and causing discomfort to the human body. In addition, when the air outlet airflows of the two column shells need to be mixed with each other, the second column shell 20 can also be configured to move with the movement of the air guide swing blades 16 to ensure that the indoor air can be mixed into the heat exchange airflow to prevent the two column shells from mixing. The air streams flow away from each other.

In this embodiment, by making the entire second column housing 20 rotatable, there is no need to design an additional air guide structure at the second air outlet 22 , making the appearance of the second column housing 20 simpler.

In addition, an air guide swing vane 16 is installed on the first column housing 10 for guiding the transverse air outlet direction of the first air outlet 12 . In this way, the intersection position of the indoor air blown out by the second air outlet 22 and the heat exchange air flow can be adjusted by changing the air outlet direction of the first air outlet 12 and/or the second air outlet 22 .

In some embodiments, as shown in FIG. 2 , a second air channel 25 connected to the second air outlet 22 is provided in the second column shell 20 to allow the non-heat exchange air flow in the second column shell 20 to flow more smoothly. Guide it to the second air outlet 22. The distance between the two transverse side walls 251 and 252 of the second air duct 25 gradually becomes smaller 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 flow can blow out of the second air outlet 22 faster, which can make up for the lack of space in the second column housing 20 to a certain extent. The negative impact of fan installation on wind speed.

In some embodiments, as shown in FIG. 2 , the air-inducing interval 13 can be made into a gradually expanding shape with a lateral dimension gradually increasing from the back to the front, so as to increase the airflow of the first air outlet 12 and the second air outlet 22 . Both can better form a negative pressure in the outlet area of the air-inducing interval 13, so that the air flow rate of the air-inducing interval 13 is larger.

A downdraft fan 35 is provided in the lower column shell 30 for transporting non-heat exchange airflow to the second column shell 20 . In this way, the installation of a fan in the second column housing 20 can be avoided, so that the second column housing 20 can be designed to be thinner, and the space of the lower column housing 30 can be more fully utilized.

A heat exchanger 17 and a first fan 14 are provided in the first column shell 10 for producing heat exchange airflow. More specifically, an air inlet 11 may be provided on the rear side and/or both lateral sides of the first column housing 10 , and a first air duct 15 is provided in the first column housing 10 . The first air duct 15 is connected to the first air outlet 12 , the first 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 airflow enters the first column shell 10 through the air inlet 11, exchanges heat with the heat exchanger 17, forms a heat exchange airflow, and then enters the first air duct 15. Guide it to the first air outlet 12, as shown in Figure 2.

FIG. 6 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 partially cut away. There are three curved dotted lines in Figure 6. The area between the two curves at the upper and middle positions is the sectioning area, and the area below the dotted line at the lowest position is the sectioning area.

As shown in Figures 5 and 6, the downwind fan 35 may include a wind wheel 351 and a volute 352. The wind wheel 351 is arranged in the volute 352, and the volute 352 is used to guide the wind direction. The exhaust side of the volute 352 is connected to the second cylinder housing 20 to discharge the non-heat exchange airflow to the second cylinder housing 20 . Moreover, the lower column shell 30 is provided with a fresh air inlet 32 and at least one indoor air inlet 31 that are both connected to the suction side of the volute 352 . The fresh air inlet 32 is connected to a fresh air duct 36 to introduce fresh air flow from the outdoors. 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 located on both transverse side walls of the lower column housing 30 . This embodiment allows the downdraft fan 35 to inhale both fresh air flow and indoor air, achieving the effect of killing two birds with one stone. In addition, a damper can be provided at the fresh air inlet 32 or the indoor air inlet 31 to control its opening and closing, thereby adjusting the intake ratio of fresh air flow and indoor air.

As shown in Figures 5 and 6, the downdraft fan 35 may also include a filter 353, which is disposed in the volute 352 to filter the fresh air flow and indoor air.

In some embodiments, if the aforementioned non-heat exchange air flow is a purification air flow, a humidification air flow or a water washing air flow, a purification module, a humidification module or a water washing module may be provided in the lower column housing 30 .

A plurality of guide fins 23 are arranged vertically in the channel 25 . Each guide fin 23 extends from front to back, and its rear end is bent downward to form a guide bend 231 . The non-heat exchange airflow flows from bottom to top. After encountering each guide plate 23, it is guided by its guide bending portion 231 and gradually changes from upward flow to forward flow. Therefore, the flow guide and bending portion 231 plays a role in changing the direction of the airflow, making the airflow turn more gentle and the wind loss smaller. There is a rounded transition between the flow guide bending portion 231 and the remaining portion of the flow guide plate 23 .

Furthermore, considering that the non-heat exchange airflow enters the second column housing 20 from the bottom of the second column housing 20 , the air outlet volume in the middle or upper part of the second air outlet 22 may be small. Therefore, in the embodiment of the present invention, a plurality of vertically arranged guide fins 23 are specially provided in the second column housing 20 , and the distance between the front and rear ends of the upper guide fins 23 is larger, so that the second air outlet 22The air outlet is more uniform in all vertical directions.
