The vertical air conditioner indoor unit provided by the invention utilizes the first cylindrical shell to blow out heat exchange airflow and utilizes the second cylindrical shell to blow out non-heat exchange airflow, and an induced air interval is formed between the first cylindrical shell and the second cylindrical shell. So, when first shell and/or second shell were out of the wind, form negative pressure environment in induced air interval department, impel the indoor air at vertical air conditioning indoor set rear to flow forward through the induced air interval to mix the air-out air current of first shell or second shell, form the drainage and mix the wind effect. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to room temperature, the comfort is higher, the wind feeling is softer, the air quantity and the air speed are increased, and the air supply distance is farther. And the non-heat exchange air flow of the second cylinder shell can be mixed into the heat exchange air flow. When the second cylinder shell blows out indoor air, a stronger air mixing effect can be achieved, and the air flow is closer to the room temperature. When the second cylinder shell 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 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.

Moreover, the second cylindrical shell can be integrally rotated, and an air guide structure is not required to be designed at the second air outlet, so that the appearance of the second cylindrical shell is simpler.
Further, considering that the non-heat exchange air flow enters the second cylindrical shell from the bottom of the second cylindrical shell, the air outlet amount of the middle part or the upper part of the second air outlet is possibly smaller. Therefore, the plurality of guide vanes which are vertically arranged are particularly arranged in the second cylinder shell, and the distances between the front end and the rear end of the guide vane which is positioned more upward are larger, so that the air outlet of the second air outlet at each vertical position is more uniform.

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 an indoor unit of a floor type air conditioner according to an embodiment of the present invention; FIG. 2 is an enlarged cross-sectional view of N-N of FIG. 1; fig. 3 is a schematic view of the indoor unit of the floor type air conditioner shown in fig. 2 after the air introduction interval is closed. Fig. 2 and 3 show the flow direction of the heat exchange gas flow by solid arrows and the flow direction of the non-heat exchange gas flow by hollow arrows.
As shown in fig. 1 to 3, the indoor unit of an upright air conditioner according to an embodiment of the present invention may generally include a first cylindrical case 10, a second cylindrical case 20, and a damper 50.
The first cylindrical shell 10 is in a vertical cylindrical shape, that is, a hollow cylindrical shell. A first air outlet 12 for blowing out heat exchange air flow is opened on the front side of the first cylindrical shell 10. 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 the compressor, the heat exchanger of the outdoor unit, the 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 column shape, that is, a hollow cylindrical shell. A second air outlet 22 for blowing out non-heat exchange air flow is opened at the front side of the second cylindrical shell 20. 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. The second column casing 20 and the first column casing 10 are arranged in the lateral direction, and an air-inducing space 13 is formed therebetween. The front and rear of the induced draft space 13 are both 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 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 used for air outlet, the indoor air in the air inducing interval 13 is driven to flow forwards under the action of negative pressure so as to be mixed with the air outlet flow of the first cylindrical shell 10 or the second cylindrical shell 20, and the air inducing and 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.
The first outlet 12 and the second outlet 22 may be a whole vertical bar extending from top to bottom, or an intermittent vertical bar formed by a plurality of vertically arranged sub-outlets, so as to fully utilize the height space of the first cylindrical shell 10 and the second cylindrical shell 20.
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.
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 heat exchange air 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.
In some embodiments, the indoor unit is configured to have an operation mode in which the heat-exchange air flow from the first outlet vent 12 and the non-heat-exchange air flow from the second outlet vent 22 are mixed in front of the indoor unit. Specifically, the normal directions of the first outlet 12 and the second outlet 22 may be clamped by an angle greater than 0, so that the two outlet air flows can be mixed. Of course, the air guide structure is used for guiding air, so that the two air outlet flows can be mixed. Thus, when the indoor air is blown out from the second cylindrical shell 20, the mixing amount of the indoor air is larger, the mixing speed is higher, a stronger air mixing effect can be realized, and the airflow is closer to the room temperature. 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.
In addition, because need not to set up the heat exchanger in the second shell 20, can be thinner with the design of second shell 20 ground, make it obviously be thinner than first shell 10, this kind of asymmetric design both had satisfied the needs of mixing the wind just, made the outward appearance of vertical air conditioning indoor set novel more unique again, had promoted the competitiveness of product. For example, 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 walls of the second cylindrical shell 20 or the first cylindrical shell 10 are farthest in the lateral direction. 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 may be flush or substantially flush with the front and rear positions of the first outlet 12, for example, with a front and rear distance of not more than 5cm, so as to achieve better mixing of the non-heat exchange air flow and the heat exchange air flow.
In some embodiments, as shown in fig. 2 and 3, 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 only the motor is required to directly drive the rotating structure.
Specifically, the damper 50 may be provided at the entrance of the air induction space 13, and be in the shape of a vertically extending prism, the outer peripheral wall portion surface of which constitutes the wind shielding face 51, and the rotation axis x1 of the damper 50 is away from the wind shielding face 51 and is located rearward of the second pillar shell 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. 3; or to a closed position behind the second housing 20. In the open position, as shown in FIG. 2, the damper 50 is positioned away from the air intake path of the induced air space 13 to provide smoother intake of air. In the open position, the wind shielding surface 51 may be directed away from the first column casing 10 (for example, in fig. 2, the first column casing 10 is located on the right side of the second column casing 20, and the wind shielding surface 51 is directed to the right).
In some embodiments, as shown in fig. 1 to 3, the indoor unit of an upright air conditioner further includes a lower cylindrical case 30. The first and second column housings 10 and 20 extend upward from the top end of the lower column housing 30. The damper 50 is mounted on the lower column housing 30. The first column housing 10 and the lower column housing 30 may be formed as an integral piece, or the second column housing 20 and the lower column housing 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 conditioner 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 connected to the upper connection case 40. The first column casing 10 and the upper connecting casing 40 may be formed as an integral piece, or the second column casing 20 and the upper connecting casing 40 may be formed as an integral piece. The connecting shell 40 is arranged in the vertical air conditioner indoor unit, so that the structure of the vertical air conditioner indoor unit is more stable, and the appearance is more harmonious.
Fig. 4 is a schematic view of the indoor unit of the floor type air conditioner shown in fig. 3 after the second cylinder casing 20 is rotated toward the lateral outside;
in some embodiments, as shown in fig. 3 and 4, the second cylindrical shell 20 may be configured to be rotatably mounted to the lower cylindrical shell 30 about a vertical axis to adjust the orientation of the second air outlet 12, so as to adjust 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. 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 air guide flap 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.
In addition, an air guide swing blade 16 for guiding the transverse air outlet direction of the first air outlet 12 is mounted on the first cylindrical shell 10. Therefore, the intersection position of the indoor air blown out from the second outlet 22 and the heat exchange airflow can be adjusted by changing the air outlet direction of the first outlet 12 and/or the second outlet 22.
In some embodiments, as shown in fig. 2, a second air duct 25 communicating with the second air outlet 22 is disposed in the second cylindrical shell 20, so that the non-heat-exchange air flow 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.

As shown in fig. 5 and 6, downwind turbine 35 may include a wind wheel 351 and a volute 352, where wind wheel 351 is disposed within volute 352, and volute 352 is used to direct the wind. 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 column shell 30, and the number of the indoor air inlets 31 is two, and the two fresh air inlets are located on two lateral walls of the lower column shell 30 respectively. 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, the fresh air inlet 32 or the indoor air inlet 31 can be provided with an air door to control the opening and closing or the opening of the fresh air inlet or the indoor air inlet, so that the air inlet ratio of the fresh air flow to the indoor air is adjusted.
As shown in fig. 5 and 6, 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.
In some embodiments, if the non-heat exchange gas stream is a purge gas stream, a humidification gas stream, or a water wash gas stream, a purge module, a humidification module, or a water wash module may be disposed in the lower column housing 30.
In some embodiments, as shown in fig. 6, the second air outlet 22 is a vertical bar, a vertical bar-shaped second air duct 25 communicating with the second air outlet 22 is disposed in the second cylindrical shell 20, a plurality of flow deflectors 23 arranged along the vertical direction are disposed in the second air duct 25, each flow deflector 23 extends from front to back, and the rear end of each flow deflector 23 is bent downward to form a flow guiding bending portion 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 of changing the direction of the airflow, so that the turning of the airflow is smoother, and the wind power 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 arranged in the vertical direction 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.
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.
