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 an embodiment of the present invention, and the flow direction of air flow is indicated by solid arrows in fig. 2 to 5, and referring to fig. 2 to 6, the vertical air conditioning indoor unit according to an embodiment of the present invention includes a first cylindrical casing 10, a second cylindrical casing 20, and a third cylindrical casing 30.
The first cylindrical shell 10 is in a vertical column shape, and a first air outlet 11 for blowing out a first airflow is formed in the front side of the first cylindrical shell 10. The second cylindrical shell 20 is in a vertical column shape, and a second air outlet 21 for blowing out a second air flow is formed in the front side of the second cylindrical shell 20. The second cylindrical shell 20 is disposed at one lateral side of the first cylindrical shell 10, and an induced air space 16 is formed between the second cylindrical shell 20 and the first cylindrical shell 10, so that air in the induced air space 16 is driven to flow forward by a negative pressure effect when the air is discharged from the first air outlet 11 and/or the second air outlet 21. The third cylindrical shell 30 is a vertical cylinder, and a third air outlet 31 for blowing a third air flow is opened on the front side of the third cylindrical shell 30. The third column casing 30 is rotatably disposed around the first vertical axis at the rear side of the induced draft interval 16.
The vertical air conditioner indoor unit comprises a large first cylindrical shell 10, two small second cylindrical shells 20 and a third cylindrical shell 30, wherein the second cylindrical shell 20 is positioned on one side of the first cylindrical shell 10 in the transverse direction, and the third cylindrical shell 30 is positioned on the rear side of an induced air interval 16. The third cylindrical housing 30 can rotate to direct the outlet air of the third outlet 31 to different angles. The first column shell 10, the second column shell 20 and the third column shell 30 respectively have a first air outlet 11, a second air outlet 21 and a third air outlet 31 which are independent of each other. The first column shell 10, the second column shell 20 and the third column shell 30 can respectively and independently supply air, and can also supply air simultaneously, or realize diversified multi-angle air supply 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 independently blown. For another example, the air guide flap at the first air outlet 11 and the air guide flap at the second air outlet 21 swing to make the first cylindrical shell 10 and the second cylindrical shell 20 simultaneously discharge air to the front of each other, that is, in the uniform air mode, a negative pressure environment is formed at the air introduction space 16 to promote the indoor air at the rear of the indoor unit of the vertical air conditioner to flow forward through the air introduction space 16 to mix with the discharged air flow of the first cylindrical shell 10 and the second cylindrical shell 20, thereby forming a flow guide air mixing effect. The temperature of the mixed air flow is closer to the room temperature, the comfort is higher, and the wind feeling is softer, namely the soft wind. When the second cylinder 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 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. Particularly, when the first cylindrical shell 10 and the second cylindrical shell 20 are blown out forward of each other, the third cylindrical shell 30 blows out a third airflow, and as the orientation of the third air outlet 31 changes, as shown in fig. 3, the third airflow may be converged into the mixed airflow through the air-inducing interval 16, so as to enhance the mixed airflow, increase the air volume and the air speed, and further increase the air-blowing distance. As shown in fig. 4, the third air outlet 31 can also face a direction away from the first cylindrical shell 10, so that the air-mixing airflow is sent out from the vertical air-conditioning chamber, and the air supply angle is increased, thereby meeting various requirements of users on the air supply angle of the vertical air-conditioning chamber.
In some embodiments of the present invention, the ratio of the width of the second column shell 20 in the transverse direction to the width of the first column shell in the transverse direction 10 is less than 1/2. The ratio of the depth dimension of the second column housing 20 in the front-rear direction to the depth dimension of the first column housing in the front-rear direction is less than 1/2. The first outlet 11 is vertical bar shaped, and the second outlet 21 is vertical bar shaped. The first outlet 11 and the second outlet 21 are arranged in a transverse direction. The distance between the two lateral side walls of the second cylinder shell 20 becomes gradually smaller from back to front, forming a tapered shape.
The ratio of the width of the third cylindrical shell 30 in the lateral direction to the width of the first cylindrical shell 10 in the lateral direction is less than 1/2. The ratio of the depth dimension of the third column case 30 in the front-rear direction to the depth dimension of the first column case 10 in the front-rear direction is less than 1/2. The distance between the two side walls of the third column shell is gradually reduced from back to front to form a gradually reduced shape.
The arrangement can make the second outlet 21 flush or substantially flush with the front and rear positions of the first outlet 11, so that the air flows from the second outlet 21 and the first outlet 11 can be better mixed. The second cylindrical shell 20 and the third cylindrical shell 30 are both tapered, so that the wind speed of the second air outlet 21 and the third air outlet 31 is increased, and air supply to a far place by the second cylindrical shell 20 and the third cylindrical shell 30 is facilitated. The second cylindrical shell 20 and the third cylindrical shell 30 are obviously smaller than the first cylindrical shell 10, so that two small and one large cylindrical shells arranged at intervals are formed, the appearance is stable and unique, and the decorative attribute of the household air conditioner is enhanced.
In some embodiments of the present invention, the third column housing 30 is disposed at the rear side of the second column housing 20. The first vertical axis is located in the third cylindrical shell 30, and the first vertical axis and the third air outlet 31 are arranged at intervals. The third cylindrical shell 30 can rotate to a side of the third air outlet 31 facing the second cylindrical shell 20 and far away from the first cylindrical shell 10. Set up in one side of first column shell 10 around second column shell 20 and third column shell 30, both beautifully increased the air-out angle again, especially when second column shell 20 and third column shell 30 are out of wind towards the place ahead each other, third column shell 30 rotates to third air outlet 31 and keeps away from first column shell 10 one side towards second column shell 20, both can realize even wind function, has enlarged the air supply scope again, and the angle of blowing is wider, and user experience is better.
In some embodiments of the invention, the second column housing is rotatably disposed about a second vertical axis. The second vertical axis is located in the second cylindrical shell 20, and the second vertical axis and the second air outlet 21 are arranged at intervals. The second cylindrical housing 20 rotates to blow air so that the air outlet angle of the second cylindrical housing 20 is larger, and the air outlets of the second cylindrical housing 20 and the third cylindrical housing 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 also simultaneously blow air in one direction, and at this time, the air outlet angle is expanded from about 100 degrees to about 120 degrees when the air is separately discharged from the first column casing 10.
In some embodiments of the present invention, the distance between any point on the outer edge of the cross-sectional profile of the third column shell 30 and the first vertical axis is less than the distance between the first vertical axis and the outer edge of the cross-sectional profile of the first column shell 10 closest to the first vertical axis. The distance from any point on the outer edge of the cross-sectional profile of the third column shell 30 to the first vertical axis is less than the distance from the outer edge of the cross-sectional profile of the second column shell 20 closest to the second vertical axis. The arrangement enables the third cylindrical shell 30 to rotate 360 degrees without interference, and greatly enlarges the air supply angle of the indoor unit of the vertical air conditioner. Of course, in some alternative embodiments, the third cylinder housing 30 may also be rotated 360 degrees by non-simultaneous rotation of the second cylinder housing 20 and the third cylinder housing 30, that is, the rotation of the second cylinder housing 20 is used for abdicating, and the second cylinder housing 20 is returned after the third cylinder housing 30 is rotated, so that the structure may be more compact.
In some embodiments of the invention, the vertical air conditioning indoor unit further comprises a first through-flow fan 15 and a heat exchanger 14. A first crossflow blower 15 and a heat exchanger 14 are disposed within the first shell 10. The rear wall and the rear portions of the two side walls of the first cylindrical shell 10 are provided with first air inlets 13 communicated with the first air outlets 11.
The first air inlet 13 is communicated with indoor air, and the first through-flow fan 15 causes the indoor air to enter the first column shell 10 through the first air inlet 13 and to be blown out of the first air outlet 13 as heat exchange air after passing through the heat exchanger 14.
In some embodiments of the present invention, the indoor stand air conditioner further includes a second crossflow blower 24 and a third crossflow blower 34. The second crossflow blower 24 is vertically disposed inside the second casing 20. The second crossflow blower 24 is coaxial with the second vertical axis. This arrangement eliminates the need for the second crossflow blower 24 to follow the rotation during the rotation of the second casing 20, thereby making the rotation structure of the second casing 20 simple.
A third crossflow blower 34 is vertically disposed inside the third casing 30. The third crossflow blower 34 is coaxial with the first vertical axis. This arrangement eliminates the need for the third crossflow blower 34 to follow the rotation during the rotation of the third casing 30, thereby making the rotation structure of the third casing 30 simple.
The rear part of the side wall of the second cylindrical shell 20 far away from the first cylindrical shell 10 and the rear wall of the second cylindrical shell 20 are both provided with a second air inlet 23 communicated with the second air outlet 21. The second air inlet 23 is communicated with the indoor air, and the second cross-flow fan 24 causes the indoor air to enter the second cylindrical shell 20 through the second air inlet 23 and to be blown out from the second air outlet 21.
The rear part of the side wall of the third cylindrical shell 30 far away from the first cylindrical shell 10 and the rear wall of the third cylindrical shell 30 are both provided with a third air inlet 33 communicated with the third air outlet 31. The third air inlet 33 is communicated with the indoor air, and the third cross flow fan 34 causes the indoor air to enter the third cylindrical shell 30 through the third air inlet 33 and to be blown 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 and third column casings 20 and 30 blow out the indoor air. In the uniform air mode, when the second cylindrical shell 20 and the third cylindrical shell 30 blow out indoor air, a stronger air mixing effect can be achieved, so that the air flow is closer to the room temperature.
In some embodiments of the present invention, the lower end of the second cylindrical housing 20 is provided with an air inlet communicated with the second air outlet 21. The lower end of the third cylindrical shell 30 is provided with an air inlet communicated with the third air outlet 31. The indoor unit of a floor type air conditioner further includes a lower case 40 and a third induced air fan 41. The lower case 40 is disposed below the second and third column cases 20 and 30. The third induced draft fan 41 is disposed in the lower case 40 for introducing the second and third airflows into the second and third column cases 20 and 30. The rear 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 is communicated with an air inlet of the third induced draft fan 41, and a functional module 42 is arranged in front of the air inlet of the third induced draft fan 41. The functional module 42 is a purification module and/or a humidification module.
In the above arrangement, the third induced air fan 41 is disposed in the lower shell 40, so that the fans do not need to be disposed inside the second cylindrical shell 20 and the third cylindrical shell 30, and the second cylindrical shell 20 and the third cylindrical shell 30 can be thinner in appearance and unique in shape. The air inlet of the second cylindrical shell 20 and the air inlet of the third cylindrical shell 30 are disposed at 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 causes fresh air and/or indoor air entering from the outdoor fresh air inlet 43 and/or the indoor air inlet to enter the second cylindrical shell 20 and the third cylindrical shell 30 from the air inlet of the second cylindrical shell 20 and the air inlet of the third cylindrical shell 30 and to be blown out from the second air outlet 21 and the third air outlet 31. The arrangement enables the third induced draft fan 41 to suck fresh air flow and indoor air, and achieves the effect of killing two birds with one stone. The air flows from different sources enable the vertical air conditioner indoor unit to have various air outlet types. Simultaneously for satisfying user's diversified demand, can be provided with functional module 42 in third induced air fan's air intake the place ahead, functional module 42 can be for purifying module and/or humidification module, and the second air current is one or more in room air, new trend air current, purification air current, humidification air current or the washing air current promptly, and the third air current is one or more in room air, new trend air current, purification air current, humidification air current or the washing air current.
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 and third cylindrical casings 20 and 30 through a wind dividing mechanism. In some embodiments of the present invention, a valve may be disposed between the outdoor fresh air inlet 43 and the air inlet of the third induced air blower, and between the indoor air inlet and the air inlet of the third induced air blower. A valve is provided to controllably communicate one of the outdoor fresh air inlet 43 and the indoor air inlet with the air inlet of the third induced draft fan. This arrangement allows the second 20 and third 30 housings to controllably blow fresh or room air.
In some embodiments of the invention, separate fans are used for the intake air of the second column shell and the intake air of the third column shell. Specifically, the vertical air conditioner indoor unit further comprises a first induced air fan and a second induced air fan, the second cylindrical shell 20 enters air from an air inlet at the lower end of the second cylindrical shell through the first induced air fan, and the third cylindrical shell 30 enters air from an air inlet at the lower end of the third cylindrical shell through the second induced air fan.
In some embodiments of the present invention, the second cylindrical shell 20 is supplied with air from an air inlet at the lower end of the second cylindrical shell by a first induced draft fan, and the third cylindrical shell 30 is supplied with air from the rear of the third cylindrical shell by a third cross flow fan. In this embodiment, the inlet air of the second cylindrical shell and the inlet air of the third cylindrical shell adopt different inlet air modes.
In some embodiments of the present invention, as shown in fig. 6, a vertical bar-shaped first air duct 28 communicating with the second air outlet 21 is disposed in the second cylindrical shell 20, and the air flow entering the first air duct 28 is a first air flow. A plurality of first flow deflectors 25 arranged vertically are arranged in the first air duct 28, each first flow deflector 25 extends from front to back, the rear end of each first flow deflector 25 is bent downwards to form a first flow guiding bent part 251, and the distance between the front end and the rear end of the first flow deflector 25 which is closer to the position is larger.
The first air flow flows from bottom to top, and after encountering each first flow deflector 25, is guided by the first flow guiding bending part 251 thereof, and gradually changes from top to front. Therefore, the first diversion bent part 251 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 first guide bending part 251 and the rest of the first guide vane 25 are in rounded transition.
Further, considering that the first air flow enters the second casing 20 from the bottom of the second casing 20, the air outlet amount at the middle or upper part of the second air outlet 21 may be small. Therefore, in the embodiment of the present invention, particularly, the plurality of first baffles 25 vertically arranged are disposed in the second column shell 20, and the distance between the front end and the rear end of the first baffle 25 located above is larger, so that the air outlet of the second air outlet 21 at each vertical position is more uniform. Of course, the problem of small air output quantity 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 air can be supplied to places needing cold quantity, namely places needing no soft air.
In some embodiments of the present invention, a second vertical air duct is disposed in the third cylindrical shell 30 and is communicated with the third air outlet 31, and the air flow entering the second air duct is a second air flow. A plurality of second flow deflectors vertically arranged are arranged in the second air duct, each second flow deflector extends from the front to the back, the rear end of each second flow deflector bends downwards to form a second flow deflector bending part, and the distance between the front end and the rear end of each second flow deflector, which is closer to the position, is larger.
The second airflow flows from bottom to top, is guided by the second flow guide bending part after meeting each second flow guide piece, and gradually changes from top to front. Therefore, the second diversion bent part plays a role in changing the direction of the airflow, so that the airflow is more gradually turned and the wind power loss is less. The second flow guide bending part and the rest parts of the second flow guide sheet are in round angle transition.
Further, considering that the second air flow enters the third cylindrical shell 30 from the bottom of the third cylindrical shell 30, the air output at the middle or upper part of the third air outlet 31 may be slightly smaller. Therefore, in the embodiment of the present invention, a plurality of second flow deflectors which are vertically arranged are particularly arranged in the third cylindrical shell 30, and the distance between the front end and the rear end of the second flow deflector which is positioned on the upper side is larger, so that the air outlet of the third air outlet 31 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. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
