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 an embodiment of the present invention, and Fig. 2 is an enlarged N-N sectional view of Fig. 1 . FIG. 2 shows the flow direction of the heat-exchanging air flow with solid arrows, and the flow direction of the non-heat-exchange air flow with hollow arrows.

As shown in FIG. 1 and FIG. 2 , the vertical air conditioner indoor unit according to the embodiment of the present utility model 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. A first air outlet 12 for blowing out heat exchanging air is opened 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. 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. A second air outlet 22 for blowing out non-heat exchange air is opened on the front side of the second column shell 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 role is to assist in adjusting the indoor environment. Moreover, the second column shell 20 is arranged laterally with the first column shell 10 , and a wind-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, the indoor air in the air-inducing compartment 13 is driven to flow forward by the action of negative pressure.

The first air outlet 12 and the second air outlet 22 can be integral vertical strips extending from top to bottom, or can also be intermittent vertical strips composed of multiple sub-air outlets arranged vertically, so as to make full use of the first air outlet. The height space of the first cylindrical shell 10 and the second cylindrical shell 20.

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 present utility model, when the first column shell 10 and/or the second column shell 20 blow out the air, a negative pressure environment is formed at the air-introduction space 13, so that the indoor air behind the indoor unit of the vertical air conditioner passes through the air-induction space 13 to flow forward to mix with the air flow out of the first column shell 10 or the second column shell 20 to form the effect of drainage and air mixing. 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.

In some embodiments of the present utility model, the vertical air conditioner indoor unit is also configured to: have the heat exchange air flow blown out of the first air outlet 12 and the non-heat exchange air flow blown out of the second air outlet 22 in front of the vertical air conditioner indoor unit. Mixed mode of operation. Specifically, the normal direction of the first air outlet 12 and the second air outlet 22 can be clamped at an angle greater than 0, so that the two air outlets can mix. Of course, the air guide structure is also used to guide the air, so that the two outlet air streams can be mixed. In this way, when the indoor air is also blown out from the second column shell 20, the indoor air is mixed in a larger amount and at a faster mixing speed, thereby achieving a stronger air mixing effect and making the air flow closer to the 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 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.

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.

For example, the ratio of the width of the second cylindrical case 20 in the lateral direction to the width of the first cylindrical case 10 in the lateral direction may 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.

In some embodiments, as shown in FIG. 2 , a second air passage 25 communicating with the second air outlet 22 is provided in the second column housing 20 for the non-heat exchange air flow in the second column housing 20 to flow more smoothly. Lead to the second air outlet 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.

In some embodiments, as shown in FIG. 2 , the air-introduction interval 13 can be made into a gradually expanding shape in which the lateral dimension gradually increases from the rear to the front, so that the air flow 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 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.

In some embodiments, as shown in FIG. 2 to FIG. 5 , an air guide 26 for guiding the second air outlet 22 in a transverse 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, the first column shell 10 is installed with an air guide swing vane 16 for guiding the first air outlet 12 in a transverse air outlet direction.

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

In some embodiments, as shown in FIG. 3 , the air guiding member 26 may include a first board body 261 and a second board body 262 arranged laterally at intervals. 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 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 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 air guide member 26 is rotated counterclockwise relative to the state shown in FIG. 2 , so that the air guide channel 260 is directed to the right front, so as to guide the non-heat exchange air flow 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.

In some embodiments, as shown in FIG. 3 , a second air channel 25 communicating with the second air outlet 22 may 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 air guiding member 26 rotates to a lateral limit angle, the first plate body 261 is extended into the receiving groove 2512, so that the air guiding surface of the bent portion 2611 is flush 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 guiding channel 260 from the second air channel 25 more smoothly. Similarly, when the air guiding member 26 rotates to another lateral limit angle, the second plate body 262 is embedded in the recessed portion 2523, so that the air guiding surface of the second plate body 262 and the lateral side wall 252 of the second air channel 25 The surface 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.

In some embodiments, the second air outlet 22 can be closed by using the air guide 26 . As shown in FIG. 6 , the air guiding 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 .

In some embodiments, as shown in FIG. 7 , the vertical air conditioner indoor unit further includes a lower column shell 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 dotted lines in Figure 8, the area between the upper and middle curves is the section area, and the area below the lowermost dotted line is the section 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.

In some embodiments, 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 shell 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.
