[0025] Optionally, the vertical air conditioner indoor unit further comprises:

[0026] A lower shell is arranged below the second column shell;

[0027] A second air flow fan is arranged in the lower shell, and is used to promote the second air flow to enter the second column shell from the lower end of the second column shell and flow out from the second air outlet;

[0029] Optionally, the vertical air conditioner indoor unit further comprises:

[0030] An air duct is arranged in the second column shell and is used to communicate the second air outlet;

[0031] A plurality of guide vanes are arranged in the air duct in vertical arrangement, each of the guide vanes extends from front to back, and the rear end is bent downward to form a guide bending part; the front and rear ends of the guide vanes located higher have a greater distance.

[0032] The indoor unit of the vertical air conditioner of the present application comprises a long first column shell and two short second column shells and a third column shell, the third column shell is located above the second column shell, and the first column shell, the second column shell and the third column shell respectively have independent first air outlet, second air outlet and third air outlet. The first column shell, the second column shell and the third column shell can respectively send air alone, or simultaneously send air, or through the setting of the air outlet direction of the first air outlet, the second air outlet and the third air outlet, diversified multi-angle air supply can be realized, and the demand of multiple users in the same indoor space for the air supply angle of the vertical air conditioner indoor unit is met. In particular, the second column shell is rotatably arranged, and the air outlet direction of the second air flow can be changed. The third column shell is rotatably arranged, and the air outlet direction of the third air flow can be changed. Different air outlet effects and more air outlet forms can be obtained, the individual needs of users are met, and the user experience is improved.

[0033] Further, the first column shell blows out heat exchange air flow, the second column shell blows out indoor air and / or fresh air flow, and the third column shell blows out indoor air. The first column shell and the second column shell form a first air guide interval, and the first column shell and the third column shell form a second air guide interval. In this way, when the first column shell and / or the third column shell blows air, a negative pressure environment is formed at the air guide interval, and the indoor air behind the vertical air conditioner indoor unit flows forward through the first air guide interval to mix into the air flow of the first column shell and / or the third column shell, forming a flow guide and air mixing effect. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, the comfort is higher, the wind feeling is softer, the air volume and air speed are increased, and the air supply distance is farther. Moreover, when the third column shell blows out indoor air, a stronger air mixing effect can be achieved, and the air flow is closer to room temperature. When the first column shell and / or the second column shell blows air, similar effects are also achieved. Moreover, when the second column shell blows out adjustment air flow such as fresh air flow, purification air flow, humidification air flow or water washing air flow, the adjustment air flow can be mixed with the heat exchange air flow earlier and more, the mixing rate is increased, and the adjustment air flow is better diffused to various places in the room.

[0034] Further, considering that the indoor air and / or fresh air flow enters the second column shell from the bottom of the second column shell, the air volume of the middle or upper part of the second air outlet may be small. Therefore, the present application particularly provides a plurality of vertically arranged guide vanes in the second column shell, and the front and rear ends of the guide vanes located higher are farther apart, so that the air outlet of the second air outlet is more uniform in the vertical direction.

[0035] Further, in the vertical air conditioner indoor unit of the present application, the second column shell is obviously smaller than the first column shell, so that the appearance is very unique, and the decoration property of the household air conditioner is enhanced.

[0063] The present application provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of a split air conditioner, which is used to adjust indoor air, such as refrigeration / heat, dehumidification, introduction of fresh air, etc. The vertical air conditioner indoor unit can be a conventional floor-standing cabinet machine, or a vertical wall-mounted machine.

[0064] Figure 1 is a schematic front view of the second column shell and the third column shell of the vertical air conditioner indoor unit of an embodiment of the present application blowing air forward, Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 13 、 Figure 14 、 Figure 16 and Figure 17 the flow direction of the air flow is shown by solid arrows, and the reference Figures 2 to 22As shown, the embodiment of the present application provides a vertical air conditioner indoor unit, which comprises a first column shell 10, a second column shell 20 and a third column shell 30.

[0065] The first column shell 10 is vertically columnar, and the front side of the first column shell 10 is provided with a first air outlet 11 for blowing out a first air flow. The second column shell 20 is vertically columnar, and the front side of the second column shell 20 is provided with a second air outlet 21 for blowing out a second air flow. The third column shell 30 is vertically columnar, and the front side of the third column shell 30 is provided with a third air outlet 31 for blowing out a third air flow.

[0066] The third column shell 30 is above the second column shell 20, and the second column shell 20 and the first column shell 10 are arranged in a transverse direction, with the first column shell 10 being higher than the second column shell 20. The second column shell 20 and the third column shell 30 are rotatably arranged around the same vertical axis.

[0067] The vertical air conditioner indoor unit of the present application comprises a long first column shell 10 and two short second column shell 20 and third column shell 30, the third column shell 30 is above the second column shell 20, the first column shell 10, the second column shell 20 and the third column shell 30 have independent first air outlet 11, second air outlet 21 and third air outlet 31 respectively. The first column shell 10, the second column shell 20 and the third column shell 30 blow out the air flow introduced into themselves, and the air outlet direction of the first air outlet 11, the second air outlet 21 and the third air outlet 31 can be set to blow air to multiple directions at the same time, meeting the needs of multiple users in the same indoor space for multiple air supply angles of the vertical air conditioner indoor unit. The first column shell 10, the second column shell 20 and the third column shell 30 can also independently supply air according to the needs of the user. In particular, when the second air outlet 21 and the first air outlet 11 have the same air outlet angle, the air flows of the second air outlet 21 and the first air outlet 11 can be mixed and blown out in front of the second air outlet 21 and the first air outlet 11. When the third air outlet 31 and the first air outlet 11 have the same air outlet angle, the air flows of the third air outlet 31 and the first air outlet 11 can be mixed and blown out in front of the third air outlet 31 and the first air outlet 11, so that the air flow blown out by the vertical air conditioner indoor unit is softer and more comfortable. In particular, the second column shell 20 is rotatably arranged, and the air outlet direction of the second air flow can be changed. The third column shell 30 is rotatably arranged, and the air outlet direction of the third air flow can be changed, so that different air outlet effects and more air outlet forms can be obtained, meeting the individual needs of users and improving the user experience. For example, Figure 1 and Figures 4 to 17 As shown, in the case that the first air outlet 11 blows air to the left, when the second air outlet 21 and the third air outlet 31 blow air to the same direction or different directions, the first air flow, the second air flow and the third air flow converge into one air flow in front of the vertical air conditioner indoor unit.

[0068] In some embodiments of the present application, 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, and the ratio of the depth of the second column shell 20 in the front-rear direction to the depth of the first column shell 10 in the front-rear direction is less than 1 / 2. The first air outlet 11 and the second air outlet 21 are arranged in the transverse direction, and the first air outlet 11 and the third air outlet 31 are arranged in the transverse direction. The first air outlet 11 is in the form of a vertical strip, the second air outlet 21 is in the form of a vertical strip, and the third air outlet 31 is in the form of a vertical strip. The above arrangement can make the front-rear positions of the second air outlet 21 and the third air outlet 31 flush or substantially flush with the first air outlet 11, so that the air flows from the second air outlet 21, the third air outlet 31 and the first air outlet 11 can be better mixed. The second column shell 20 and the third column shell 30 are significantly smaller than the first column shell 10, forming a size column arranged at intervals, which is very distinctive in appearance and enhances the decorative properties of the household air conditioner.

[0069] In some embodiments of the present application, the third column shell 30 and the second column shell 20 have the same cross-sectional profile, and the third column shell 30 and the second column shell 20 are integrally formed, which saves cost and is convenient to install.

[0070] In some embodiments of the present application, the indoor unit of the vertical air conditioner further comprises a heat exchanger 14, a heat exchange fan 15, a cross-flow fan 34, a lower shell 40 and a second airflow fan 41.

[0071] The rear wall and the rear portions of the two side walls of the first column shell 10 are each provided with a first air inlet 13 communicating with the first air outlet 11. The first air inlet 13 communicates with the indoor space, and the first column shell 10 is provided with a heat exchanger 14 and a heat exchange fan 15. The heat exchange fan 15 promotes the indoor air to enter the first column shell 10 through the first air inlet 13, and then the indoor air flows out of the first air outlet 11 of the first column shell 10 after passing through the heat exchanger 14.

[0072] The rear portion of the side wall of the third column shell 30 away from the first column shell 10 and the rear wall of the third column shell 30 are each provided with a third air inlet 33 communicating with the third air outlet 31. The first air inlet 13 is located at the rear side of the third air inlet 33. The third air inlet 33 communicates with the indoor space, and the third column shell 30 is provided with a cross-flow fan 34. The cross-flow fan 34 promotes the indoor air to enter the third column shell 30 through the third air inlet 33, and promotes the indoor air to flow out of the third air outlet 31 of the third column shell 30.

[0073] The lower end of the second column shell 20 is provided with an air inlet communicating with the second air outlet 21. The lower shell 40 is arranged below the second column shell 20, and the air inlet at the lower end of the second column shell 20 communicates with the air outlet of the second airflow fan 41 arranged in the lower shell 40. The second airflow fan 41 is used to promote the second airflow to enter the second column shell 20 and flow out of the second air outlet.

[0074] In some embodiments of the present invention, a first air-guiding interval 16 is formed between the second column shell 20 and the first column shell 10, so that when the first air outlet 11 and / or the second air outlet 21 emit air, the negative pressure will drive the air in the first air-guiding interval 16 to flow forward, so as to mix with the airflow emitted by the second column shell 20 and / or the first column shell 10, forming a ducting and mixing effect. The mixed airflow is more comfortable, the wind feels softer, and the air volume and wind speed are increased, and the air delivery distance is longer.

[0075] The third column housing 30 and the first column housing 10 form a second air-guiding interval 26, so that when the first air outlet 11 and / or the third air outlet 31 emit air, the negative pressure will drive the air in the second air-guiding interval 26 to flow forward, so as to mix with the airflow from the third column housing 30 and / or the first column housing 10, forming a ducting and mixing effect. The mixed airflow is more comfortable, the wind feels softer, and the air volume and speed are increased, and the air delivery distance is longer.

[0076] like Figure 1 and Figures 4 to 17 As shown, when the first air outlet 11 blows air to the left, the airflow direction within the first air intake interval 16 and the airflow direction within the second air intake interval 26 changes when the second air outlet 21 and the third air outlet 31 blow air in the same direction or in different directions.

[0077] The distance between the two side walls of the second column shell 20 gradually decreases from back to front, forming a tapered shape, which increases the outlet air velocity of the second air outlet 21, facilitating air delivery to distant locations. Similarly, the distance between the two side walls of the third column shell 30 gradually decreases from back to front, forming a tapered shape, which increases the outlet air velocity of the third air outlet 31, facilitating air delivery to distant locations. Both the first air intake interval 16 and the second air intake interval 26 are tapered shapes, with their lateral dimensions gradually increasing from back to front.

[0078] In some embodiments of the present invention, such as Figure 18 As shown, the side wall of the lower casing 40 has a fresh air inlet 43 that communicates with the air inlet of the second airflow fan 41 and at least one indoor air inlet. The vertical air conditioner indoor unit also includes a valve configured to controllably communicate one of the fresh air inlet 43 and the indoor air inlet with the air inlet of the second airflow fan 41.

[0079] The above arrangement enables the second air flow fan 41 to draw in fresh air and / or indoor air in a controlled manner. The fresh air inlet 43 is connected to a fresh air duct to draw in fresh air from outside. The fresh air inlet 43 is located on the rear wall of the lower shell 40, and the indoor air inlets are two in number and located on the lateral side walls of the lower shell 40. This arrangement enables the second air flow fan 41 to draw in both fresh air and indoor air, achieving a one-stroke two-effect result. In addition, a valve can be arranged at the fresh air inlet 43 or the indoor air inlets to control the opening and closing or opening degree thereof, thereby adjusting the air intake ratio of fresh air and indoor air.

[0080] In some embodiments of the present application, in order to detect the indoor air quality, a sensor is arranged at a suitable position inside the indoor unit of the vertical air conditioner and in contact with indoor air to monitor the indoor air quality in real time. When the sensor detects that the oxygen content of the indoor air is low, the second column shell 20 needs to draw in clean fresh air, and when the sensor detects that the humidity of the indoor air is low, the second column shell 20 needs to draw in humidified indoor air. In order to meet the user's requirements for indoor air quality, a functional module 42 is arranged at the air inlet of the second air flow fan 41, so that the air entering the air inlet of the second air flow fan 41 first passes through the functional module 42. The functional module 42 can be a purification module and / or a humidification module.

[0081] In some embodiments of the present application, as shown in Figure 18 The second column shell 20 is provided with a vertical strip-shaped air duct 28 communicating with the second air outlet 21, and the lower end of the air duct 28 is the air inlet thereof. The air duct 28 is provided with a plurality of guide vanes 25 arranged in the vertical direction, each guide vane 25 extends from front to back, and the rear end is bent downward to form a guide bending part 251. The second air flow flows from bottom to top, and after encountering each guide vane 25, it is guided by the guide bending part 251 and gradually changes from upward flow to forward flow. The guide bending part 251 plays a role in changing the direction of the air flow, making the turning of the air flow more gentle and the wind power loss smaller. The guide bending part 251 and the rest of the guide vane 25 are transitioned with a round corner.

[0082] Further, considering that the second air flow enters the second column shell 20 from the bottom of the second column shell 20, it is possible that the air outlet in the middle or upper part of the second air outlet 21 is smaller. Therefore, the embodiments of the present application are particularly provided with a plurality of guide vanes 25 arranged in the vertical direction in the second column shell 20, and the distance between the front end and the rear end of the guide vane 25 located higher is greater, so that the air outlet of the second air outlet 21 is more uniform in the vertical direction. Of course, the problem that the air outlet in the middle or upper part of the second air outlet 21 is smaller can also be fully utilized, so that the mixing effect of the upper side is poor, and the air can be sent to the place where cold energy is needed, i.e. to the place where soft air is not needed.

[0083] In some embodiments of the present invention, the lower end of the second column housing 20 is connected to the upper end of the third column housing 30. A vertical axis passes through the second column housing 20 and the third column housing 30, and is spaced apart from the second air outlet 21 and the third air outlet 31. A second air inlet 23 communicating with the second air outlet 21 is provided on the rear part of the side wall of the second column housing 20 away from the first column housing 10 and on the rear wall of the second column housing 20; the first air inlet is located behind the second air inlet.

[0084] Furthermore, in some embodiments of the present invention, the vertical air conditioner indoor unit further includes a cross-flow fan. The cross-flow fan is disposed within the second column housing 20 and the third column housing 30, and is used to facilitate the entry of a second airflow into the second column housing 20 and its exit from the second air outlet 21, and to facilitate the entry of a third airflow into the third column housing and its exit from the third air outlet. The vertical axis is coaxial with the cross-flow fan. In other embodiments of the present invention, there are two cross-flow fans: one cross-flow fan 24 is used to facilitate the entry of the second airflow into the second column housing and its exit from the second air outlet, and the other cross-flow fan 34 is used to facilitate the entry of the third airflow into the third column housing and its exit from the third air outlet. The two cross-flow fans are coaxial. The vertical axis is coaxial with the cross-flow fans. Of course, in this embodiment, the internal spaces of the second column housing 20 and the third column housing 30 are independent of each other.

[0085] In some embodiments of the present invention, at least one of the first airflow, the second airflow, and the third airflow is different from the others. Preferably, the second airflow and the third airflow are different. The first airflow and the third airflow may be the same or different. The first airflow and the second airflow may be the same or different. The first airflow is a heat exchange airflow. The second airflow is indoor air, fresh air, purified air, humidified air, or water washing airflow. The third airflow is indoor air, fresh air, purified air, humidified air, or water washing airflow. The inconsistency between the second and third airflows can solve the problem of a single soft air supply.

[0086] In some embodiments of the present invention, the second column housing 20 and / or the third column housing 30 are equipped with air guides for guiding the lateral airflow direction of the second air outlet 21 and / or the third air outlet 31. "Guiding the lateral airflow direction" refers to changing the angle between the airflow direction and the front-back direction, for example, directing the airflow towards the front, left front, right front, etc. Furthermore, the first column housing 10 is equipped with a first air guide plate 12 for guiding the lateral airflow direction of the first air outlet 11.

[0087] like Figure 19 As shown, taking the second column housing 20 as an example, the vertical air conditioner indoor unit can be configured such that the air guide 27 adjusts the lateral airflow direction of the second air outlet 21, allowing the second airflow to merge into the first airflow at the first air outlet 11. That is, when the first air guide plate 12 changes the airflow direction of the first airflow, the air guide 27 is activated to ensure that the second airflow always merges into the heat exchange airflow. For example...Figure 19 As shown, when the first air deflector 12 is set to blow air forward, the air deflector 27 is set to blow air forward as well. As shown, Figure 21 As shown, when the first air deflector 12 is set to blow air leftward, the air deflector 27 is set to blow air leftward as well. As shown, Figure 22 As shown, when the first air deflector 12 is set to blow air rightward, the air deflector 27 is set to blow air rightward as well. The main control board of the air conditioner can be electrically connected to the motors of the air deflector 27 and the first air deflector 12 at the same time so as to control the two to move in coordination.

[0088] In some embodiments of the present application, one side wall 281 of the air duct 28 is provided with a first clearance slot 2812 and a first sliding slot 2811 communicating with the first clearance slot 2812, and the other side wall 282 of the air duct 28 is provided with a second clearance slot 2821, and the first plate body 271 is slidingly installed in the first sliding slot 2811. As shown, Figure 20 As shown, the air deflector 27 can include the first plate body 271 and the second plate body 272 arranged transversely and spaced apart. Of course, the second plate body 272 is connected to the first plate body 271 through other structures, which are not shown in Figure 20 The end of the first plate body 271 close to the second plate body 272 has a bent portion 2711 bent rearward, and the bent portion 2711 and the second plate body 272 form an air deflection passage 270 with a gradually decreasing distance from rear to front. The air deflector 27 is rotatably installed about a vertical axis on the second columnar shell 20 so as to change the transverse air blowing direction of the second air outlet 21 by adjusting the relative position of the air deflection passage 270 and the second air outlet 21.

[0089] For example Figure 19 and Figure 20 As shown, when the air deflection passage 270 is opposite to the second air outlet 21, the non-heat-exchanged air flow is guided to blow out straight forward. As shown, Figure 21 As shown, the air deflector 27 is rotated clockwise relative to Figure 19 the state to make the air deflection passage 270 face left front so as to guide the second air flow to blow out left front. As shown, Figure 22 As shown, the air deflector 27 is rotated counterclockwise relative to Figure 19 the state to make the air deflection passage 270 face right front so as to guide the second air flow to blow out right front. The structure of the air deflector 27 of the present embodiment is very simple and occupies very small space, and is particularly suitable for the second air outlet 21 which is a thin and narrow air outlet, and is very ingenious in design.

[0090] In some embodiments of the present application, the air deflector 27 can be rotated to a first position and a second position. When the air deflector 27 is in the first position, the first bent portion 2711 is embedded in the first clearance slot 2812, and the air deflection surface of the bent portion 2711 of the air deflector 27 is on the plane formed by the rear edge of the opening of the first clearance slot 2812 and the vertical edge of the second air outlet 21 adjacent to the first clearance slot 2812. As shown,Figure 21 as shown.

[0091] When the air guide 27 is in the second position, the second plate body 272 is embedded in the second accommodation slot 2821, and the air guide surface of the second plate body 272 is on the plane formed by the rear edge of the opening of the second accommodation slot 2821 and the vertical edge of the second air outlet 21 adjacent to the second accommodation slot 2821. As shown. Figure 22

[0092] In some embodiments of the present application, the air guide 27 can be used to close the second air outlet 21. Similarly, the same air guide 27 can also be provided at the third air outlet.

[0093] Thus, those skilled in the art will recognize that the present application has been well- illustrated and described, but that various modifications can be made without departing from the spirit or scope of the present application. Accordingly, it is not intended that the present application be limited, except as by the appended claims.​
