The vertical air conditioner indoor unit utilizes the first column shell to blow out first air flow, utilizes the second column shell to blow out second air flow, and forms an induced air interval between the first column shell and the second column shell. Therefore, when the first column casing and the second column casing simultaneously discharge air to the front of each other, a negative pressure environment is formed at the induced air interval, so that indoor air behind the indoor unit of the vertical air conditioner forwards flows through the induced air interval to be mixed into the air-out air flow of the first column casing and the second column casing, and a drainage air mixing effect is formed. The temperature of the mixed air flow is closer to the room temperature, the comfort is higher, and the wind sense is softer, namely the so-called soft wind. And when the second shell blows out indoor air, a stronger air mixing effect can be realized, so that the airflow is closer to the room temperature. When the second shell blows out the fresh air flow, the purified air flow, the humidified air flow or the water washing air flow and other regulating air flows, the regulating air flows can be mixed with the heat exchange air flow earlier and more, the mixing rate is enhanced, and the mixing rate is better diffused to all parts in a room. In particular, by arranging the third column casing to blow out the third air flow, and along with the change of the direction of the third air outlet, the third air flow can be converged into the air mixing air flow through the induced air interval, so that the air quantity and the air speed are increased, the air supply distance is further, and the direction away from the first column casing can be also faced, thereby the air mixing air flow is blown out by the vertical air conditioner indoor unit, the air supply angle is increased, and various requirements of a user on the air supply angle of the vertical air conditioner indoor unit are met.
Further, in the indoor unit of the vertical air conditioner, the different and rotating arrangement of the air supply types of the second column casing and the third column casing enables the indoor unit of the vertical air conditioner to have various air supply modes. For example, the second column casing blows fresh air flow, the third column casing blows indoor air, the second column casing and the third column casing simultaneously supply air in different directions far away from the first column casing, and under the condition that mixed air flow is not generated, the vertical air conditioner indoor unit can supply air in multiple angles and supply different types of air.
In the vertical air conditioner indoor unit, the lower shell is used for introducing or preparing the second air flow and the third air flow, and the air inducing fans are arranged in the lower shell, so that the fans are not required to be arranged in the second shell and the third shell, the second shell and the third shell can be designed to be thinner than the first shell, the asymmetric design can just meet the air mixing requirement, the appearance of the vertical air conditioner indoor unit is novel and unique, and the competitiveness of products is improved.
The above, as well as additional objectives, advantages, and features of the present invention will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present invention when read in conjunction with the accompanying drawings.

The invention provides a vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner is an indoor portion of a split type air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, etc. The indoor unit of the vertical air conditioner can be a conventional floor cabinet or a vertical wall-mounted unit.
Fig. 1 is a schematic front view of a floor air conditioner indoor unit according to an embodiment of the present invention, in which the flow direction of air is indicated by solid arrows in fig. 2 to 5, and referring to fig. 2 to 6, the floor air conditioner indoor unit according to an embodiment of the present invention includes a first column casing 10, a second column casing 20, and a third column casing 30.
The first column casing 10 is in a vertical column shape, and a first air outlet 11 for blowing out a first air flow is formed in the front side of the first column casing 10. The second casing 20 is vertically cylindrical, and a second air outlet 21 for blowing out the second air flow is formed in the front side of the second casing 20. The second casing 20 is disposed at one lateral side of the first casing 10, and an induced air space 16 is formed between the second casing 20 and the first casing 10, so that when the first air outlet 11 and/or the second air outlet 21 outlet air, the air in the induced air space 16 is driven to flow forward by means of negative pressure. The third column casing 30 is in a vertical column shape, and a third air outlet 31 for blowing out a third air flow is formed in the front side of the third column casing 30. The third column casing 30 is rotatably disposed around the first vertical axis at the rear side of the induced air space 16.
The indoor unit of the vertical air conditioner of the present invention includes a large first column casing 10 and two small second column casings 20 and a third column casing 30, the second column casing 20 being located at one lateral side of the first column casing 10, and the third column casing 30 being located at the rear side of the induced air space 16. The third column casing 30 may be rotated so that the air outlet of the third air outlet 31 is directed at different angles. The first, second and third column casings 10, 20 and 30 have respective independent first, second and third air outlets 11, 21 and 31. The first column casing 10, the second column casing 20 and the third column casing 30 may supply air separately, simultaneously, or in various multi-angle through the arrangement of the air outlet directions of the first air outlet 11, the second air outlet 21 and the third air outlet 31. For example, the first column casing 10, the second column casing 20, and the third column casing 30 may be supplied with air alone. For another example, the air guiding swing blades at the first air outlet 11 swing and the air guiding swing blades at the second air outlet 21 swing, so that the first column casing 10 and the second column casing 20 simultaneously discharge air to the front of each other, namely, in the air homogenizing mode, a negative pressure environment is formed at the air guiding interval 16, and indoor air behind the vertical air conditioner indoor unit is caused to flow forwards through the air guiding interval 16 so as to be mixed into air discharging air flows of the first column casing 10 and the second column casing 20, and a drainage air mixing effect is formed. The temperature of the mixed air flow is closer to the room temperature, the comfort is higher, and the wind sense is softer, namely the so-called soft wind. When the second casing 20 blows out the conditioning air flows such as fresh air flow, purified air flow, humidified air flow or water washing air flow, the conditioning air flows can be mixed with the heat exchange air flow earlier and more, the mixing rate is enhanced, and the conditioning air flows are better diffused to all parts of a room. In particular, when the first column casing 10 and the second column casing 20 are blown out in front of each other, the third column casing 30 blows out the third air flow, and as the direction of the third air outlet 31 changes, the third air flow can be converged into the air-mixing air flow through the air-introducing gap 16 as shown in fig. 3, so that the function of reinforcing the air-mixing air flow is achieved, the air quantity and the air speed are increased, and the air supply distance is longer. As shown in fig. 4, the third air outlet 31 may also face away from the first column casing 10, so that the air supply angle is increased while the air mixing air flow is sent out from the vertical air conditioning chamber, and various requirements of users on the air supply angle of the vertical air conditioning chamber are met.
In some embodiments of the invention, 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 is less than 1/2. The ratio of the depth dimension of the second column shell 20 in the front-rear direction to the depth dimension of the first column shell in the front-rear direction is less than 1/2. The first air outlet 11 is in a vertical strip shape, and the second air outlet 21 is in a vertical strip shape. The first air outlet 11 and the second air outlet 21 are arranged along the transverse direction. The interval between the two lateral side walls of the second casing 20 becomes gradually smaller from the rear to the front, and is formed in a tapered shape.
The ratio of the width of the third column housing 30 in the transverse direction to the width of the first column housing 10 in the transverse direction is less than 1/2. The ratio of the depth dimension of the third column housing 30 in the front-rear direction to the depth dimension of the first column housing 10 in the front-rear direction is less than 1/2. The distance between the two side walls of the third column casing is gradually reduced from back to front to form a tapered shape.
The above arrangement may make the front and rear positions of the second air outlet 21 and the first air outlet 11 flush or substantially flush, so that the air flows from the second air outlet 21 and the first air outlet 11 are better mixed. The second cylindrical shell 20 and the third cylindrical shell 30 are tapered, so that the wind speeds of the second air outlet 21 and the third air outlet 31 are increased, and the second cylindrical shell 20 and the third cylindrical shell 30 are favorable for blowing air to a far distance. The second column casing 20 and the third column casing 30 are obviously smaller than the first column casing 10, so that three column casings which are two small and one large are formed at intervals, the appearance is stable, heavy and unique, and the decoration property of the household air conditioner is enhanced.
In some embodiments of the present invention, the third column housing 30 is disposed on the rear side of the second column housing 20. The first vertical axis is located in the third column casing 30, and the first vertical axis is spaced from the third air outlet 31. The third cylindrical shell 30 is rotatable to a side of the third air outlet 31 facing the second cylindrical shell 20 away from the first cylindrical shell 10. The second casing 20 and the third casing 30 are arranged on one side of the first casing 10 from front to back, which is attractive and increases the air outlet angle, especially when the second casing 20 and the third casing 30 are air-out towards the front of each other, the third casing 30 rotates to the third air outlet 31 towards the second casing 20 and away from one side of the first casing 10, which can realize the air-homogenizing function, enlarge the air supply range, and has wider air-blowing angle and better user experience.
In some embodiments of the invention, the second housing is rotatably disposed about a second vertical axis. The second vertical axis is located in the second casing 20, and the second vertical axis is spaced from the second air outlet 21. The second casing 20 rotates the blowing air so that the air outlet angle of the second casing 20 is greater, and the air outlets of the second casing 20 and the third casing 30 can be matched with each other. As shown in fig. 5, the first column casing 10, the second column casing 20, and the third column casing 30 may blow air in one direction at the same time, and the air outlet angle may be enlarged from about 100 degrees to about 120 degrees when the first column casing 10 alone is air-discharged.
In some embodiments of the present invention, any point of the outer edge of the cross-sectional profile of the third column housing 30 is less distant from the first vertical axis than the first vertical axis is distant from the outer edge of the cross-sectional profile of the first column housing 10 closest to the first vertical axis. Any point of the outer edge of the cross-sectional profile of the third column housing 30 is less distant from the first vertical axis than the first vertical axis is distant from the outer edge of the cross-sectional profile of the second column housing 20 closest to the second vertical axis. The arrangement ensures that the third column casing 30 can rotate 360 degrees without interference, and greatly enlarges the air supply angle of the vertical air conditioner indoor unit. Of course, in some alternative embodiments, the rotation of the third column casing 30 by 360 degrees can be achieved by non-simultaneous rotation of the second column casing 20 and the third column casing 30, that is, the rotation of the second column casing 20 is used for yielding, and the second column casing 20 is returned after the rotation of the third column casing 30, so that the structure is more compact.
In some embodiments of the present invention, the floor air conditioner indoor unit further includes a first through-flow fan 15 and a heat exchanger 14. The first through-flow fan 15 and the heat exchanger 14 are disposed within the first column casing 10. The rear wall and the rear portions of both side walls of the first column casing 10 are provided with first air inlets 13 communicating with the first air outlets 11.
The first air inlet 13 is communicated with indoor air, and the first through-flow fan 15 promotes the indoor air to enter the first column casing 10 through the first air inlet 13 and become heat exchange air flow after passing through the heat exchanger 14 to be blown out from the first air outlet 13.
In some embodiments of the present invention, the stand air conditioner indoor unit further includes a second cross flow fan 24 and a third cross flow fan 34. The second cross flow fan 24 is vertically disposed inside the second casing 20. The second cross-flow fan 24 is coaxial with the second vertical axis. This arrangement eliminates the need for the second cross flow fan 24 to follow the rotation during the rotation of the second casing 20, thereby simplifying the rotation structure of the second casing 20.
The third cross flow fan 34 is vertically disposed inside the third column casing 30. The third cross-flow fan 34 is coaxial with the first vertical axis. This arrangement makes the third cross flow fan 34 not required to follow rotation during rotation of the third column casing 30, thereby making the rotation structure of the third column casing 30 simple.
A second air inlet 23 communicating with the second air outlet 21 is provided on both the rear of the side wall of the second cylindrical shell 20 remote from the first cylindrical shell 10 and the rear wall of the second cylindrical shell 20. The second air inlet 23 is communicated with indoor air, and the second cross flow fan 24 promotes the indoor air to enter the second casing 20 through the second air inlet 23 and blow out from the second air outlet 21.
A third air inlet 33 communicating with the third air outlet 31 is provided on both the rear portion of the side wall of the third column casing 30, which is far from the first column casing 10, and the rear wall of the third column casing 30. The third air inlet 33 is communicated with indoor air, and the third cross flow fan 34 promotes the indoor air to enter the third column casing 30 through the third air inlet 33 and blow out from the third air outlet 31.
In the above case, the first column casing 10 blows out the heat exchange air flow, and the second column casing 20 and the third column casing 30 blow out the indoor air. In the air-homogenizing mode, when the second column casing 20 and the third column casing 30 blow out indoor air, a stronger air-mixing effect can be achieved, so that the air flow is closer to room temperature.
In some embodiments of the present invention, the lower end of the second casing 20 is provided with an air inlet communicating with the second air outlet 21. The lower end of the third column casing 30 is provided with an air inlet communicating with the third air outlet 31. The vertical air conditioner indoor unit further comprises a lower case 40 and a third induced air fan 41. The lower case 40 is disposed under the second and third column cases 20 and 30. A third induced draft fan 41 is provided in the lower case 40 for introducing the second and third airflows into the second and third column cases 20 and 30. The back side wall of the lower shell 40 is provided with an outdoor fresh air inlet 43 and/or an indoor air inlet, the outdoor fresh air inlet 43 and/or the indoor air inlet are communicated with the air inlet of the third induced draft fan 41, and the front of the air inlet of the third induced draft fan 41 is provided with a functional module 42. The functional module 42 is a purification module and/or a humidification module.
In the above arrangement, the third induced draft fan 41 is disposed in the lower casing 40, so that the fans do not need to be disposed inside the second casing 20 and the third casing 30, and the second casing 20 and the third casing 30 can be thinner in appearance and unique in shape. The air inlet of the second casing 20 and the air inlet of the third casing 30 are arranged at the respective lower ends, the outdoor fresh air inlet 41 and/or the indoor air inlet are communicated with the air inlet of the third induced air fan 41, and the third induced air fan 41 promotes fresh air and/or indoor air entering from the outdoor fresh air inlet 43 and/or the indoor air inlet to enter the inside of the second casing 20 and the third casing 30 from the air inlet of the second casing 20 and the air inlet of the third casing 30 and blow out from the second air outlet 21 and the third air outlet 31. This arrangement allows the third induced draft fan 41 to draw in both fresh air flow and indoor air, achieving a two-sided effect. The air flows from different sources enable the indoor unit of the vertical air conditioner to have various air outlet types. Meanwhile, in order to meet the needs of the diversity of users, a functional module 42 may be provided in front of the air inlet of the third induced draft fan, where the functional module 42 may be a purifying module and/or a humidifying module, that is, the second air flow is one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water-washing air flow, and the third air flow is one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water-washing air flow.
Here, the induced draft fan 41 may be a centrifugal fan or an axial flow fan, and introduces fresh air and/or indoor air to the second column casing 20 and the third column casing 30 through a wind dividing mechanism. In some embodiments of the present invention, valves may be provided between the outdoor fresh air intake 43 and the intake of the third induced draft fan and between the indoor air intake and the intake of the third induced draft fan. The valve is configured to controllably communicate one of the outdoor fresh air inlet 43 and the indoor air inlet with the air intake of the third induced draft fan. This arrangement allows the second and third housings 20, 30 to blow fresh air or room air in a controlled manner.
In some embodiments of the invention, the inlet air to the second column housing and the inlet air to the third column housing are separate fans. Specifically, the vertical air conditioner indoor unit further comprises a first induced air fan and a second induced air fan, the second casing 20 is subjected to air intake from the air inlet at the lower end of the second casing through the first induced air fan, and the third casing 30 is subjected to air intake from the air inlet at the lower end of the third casing through the second induced air fan.
In some embodiments of the present invention, the second casing 20 is fed from the air inlet at the lower end of the second casing by the first induced draft fan, and the third casing 30 is fed from the rear of the third casing by the third through-flow fan. In this embodiment, the air intake of the second column casing and the air intake of the third column casing adopt different air intake modes.
In some embodiments of the present invention, as shown in fig. 6, a first air duct 28 in a vertical bar shape is disposed in the second casing 20 and is connected to the second air outlet 21, and the air flow entering the first air duct 28 is the first air flow. A plurality of first guide vanes 25 are arranged in the first air duct 28 in a vertical manner, each first guide vane 25 extends from front to back, the rear end of each first guide vane 25 is bent downwards to form a first guide bent part 251, and the distance between the front end and the rear end of the first guide vane 25 which is positioned higher is greater.
The first air flow flows from bottom to top, and after encountering each first guide vane 25, is guided by the first guide bent portion 251 thereof, and gradually changes from upward flow to forward flow. Therefore, the first guiding bending part 251 plays a role of changing the direction of the air flow, so that the direction of the air flow is more gentle and the wind loss is smaller. The first guide bent portion 251 makes a rounded transition with the rest of the first guide vane 25.
Further, considering that the first air flow enters the second casing 20 from the bottom of the second casing 20, the air output in the middle or upper portion of the second air outlet 21 may be smaller. Therefore, in the embodiment of the present invention, the plurality of first deflectors 25 are disposed in the second casing 20, and the distance between the front end and the rear end of the first deflector 25 located above the first deflector is greater, so that the air outlet of the second air outlet 21 is more uniform in all vertical positions. Of course, the problem of small air output in the middle or upper part of the second air outlet 21 can be fully utilized, so that the air mixing effect on the upper side is poor, and the air can be supplied to the place where the cooling capacity is needed, namely, the place where the soft air is not needed.
In some embodiments of the present invention, a second air duct in a vertical bar shape is disposed in the third column casing 30 and is connected to the third air outlet 31, and the air flow entering the second air duct is the second air flow. A plurality of second guide vanes are arranged in the second air duct along the vertical direction, each second guide vane extends from front to back, the rear end of each second guide vane is bent downwards to form a second guide bent part, and the distance between the front end and the rear end of each second guide vane which is positioned higher is greater.
The second air flow flows from bottom to top, and after encountering each second guide vane, is guided by the second guide bending part of the second air flow, and gradually changes from upward flow to forward flow. Therefore, the second diversion bending part plays a role in changing the airflow direction, so that the airflow steering is more gentle and the wind loss is smaller. The second flow guiding bending part and the rest part of the second flow guiding sheet are in round corner transition.
Further, considering that the second air flow enters the third column casing 30 from the bottom of the third column casing 30, the air output in the middle or upper portion of the third air outlet 31 may be smaller. Therefore, in the embodiment of the present invention, a plurality of vertically arranged second guide vanes are particularly disposed in the third column casing 30, and the distance between the front end and the rear end of the second guide vane located further upward is greater, so that the air outlet of the third air outlet 31 in each vertical position is more uniform.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
