Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, in particular to a vertical air-conditioning indoor unit. Background Art

[0002] The appearance of existing vertical air conditioner indoor units is not significantly different, and the user experience is not good based on the existing air supply method, resulting in many complaints from users. When using air conditioning for cooling, users often encounter a set of contradictory problems: the air outlet temperature is low, the wind speed is high, and the wind is uncomfortable, which is what people often say is that the wind is too "hard" and not soft enough. Combining user pain points and industry development trends, a soft wind experience feature is proposed. Research has found that if a portion of indoor air can be mixed into the cold air of the air conditioner, the temperature of the air flow after mixing will rise by 1°-3°, and the feeling of blowing on the body will also be softer and more comfortable. Existing air conditioners also have the disadvantage of a single soft wind supply.

[0003] People are increasingly concerned about health issues and are paying more attention to indoor air quality. However, the current function of air conditioners is often limited to regulating indoor temperature and does not have air conditioning functions such as purification and sterilization. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a vertical air-conditioning indoor unit that overcomes the above problems or at least partially solves the above problems, which can solve the problems of the air-conditioning blowing being too "hard" and the soft air supply being single and unable to adjust the air quality, and achieve the effect of diversifying the soft air supply and improving the indoor air quality.

[0037] The vertical air conditioner indoor unit further includes a valve configured to controllably connect one of the fresh air inlet and the indoor air inlet to the air inlet of the second air flow fan;

[0038] A functional module is provided at the air inlet of the second airflow fan, so that the air entering the air inlet of the second airflow fan first passes through the functional module;

[0039] The functional module is a purification module and / or a humidification module.

[0040] Optionally, the vertical air-conditioning indoor unit further includes a sensor for monitoring indoor air.

[0041] Optionally, the vertical air conditioner indoor unit further includes:

[0042] an air duct, the air duct being arranged in the second column housing and being connected to the second air outlet;

[0043] A plurality of guide vanes arranged vertically are provided in the air duct, each of the guide vanes extends from front to back, and the rear end is bent downward to form a guide bend portion; the upper the guide vane is, the greater the distance between the front and rear ends is.

[0044] The vertical air-conditioning indoor unit of the present invention 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. The first column shell, the second column shell and the third column shell respectively have their own 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 supply air separately or simultaneously, or the air outlet directions of the first air outlet, the second air outlet and the third air outlet can be set to achieve diversified and multi-angle air supply, thereby meeting the needs of multiple users in the same indoor space for the air supply angle of the vertical air-conditioning indoor unit. Moreover, it can accelerate indoor air circulation, improve heat exchange efficiency, and thus improve energy efficiency, with obvious energy-saving effects. In particular, when the outlet angles of the second and first air outlets are aligned, the air from the second and first air outlets can be mixed in front of the second and first air outlets before being blown out. When the outlet angles of the third air outlet are aligned with the first air outlet, the air from the third and first air outlets can be mixed in front of the third and first air outlets before being blown out. The inconsistency between the second and third airflows can solve the problem of single soft air supply.

[0045] Furthermore, the first column shell is used to blow out the heat exchange airflow, the second column shell is used to blow out the indoor air and / or fresh air flow, and the third column shell is used to blow out the indoor air. A first induced draft interval is formed between the first column shell and the second column shell, and a second induced draft interval is formed between the first column shell and the third column shell. In this way, when the first column shell and / or the third column shell discharges air, a negative pressure environment is formed at the second induced draft interval, prompting the indoor air behind the vertical air-conditioning indoor unit to flow forward through the second induced draft interval to mix with the outlet airflow of the first column shell and / or the third column shell, forming an induced mixed air effect. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, and it is more comfortable, the wind feels softer, and the air volume and wind speed are increased, and the air supply distance is longer. In addition, when the third column shell blows out the indoor air, a stronger mixed air effect can be achieved, making the airflow closer to room temperature. When the first column shell and / or the second column shell blows out air, there are similar effects as mentioned above. Moreover, when the second column shell blows out regulated airflows such as fresh air, purified airflow, humidified airflow or water-washed airflow, these regulated airflows can be mixed with the heat exchange airflow earlier and more, thereby enhancing the mixing rate and allowing it to diffuse better to various parts of the room.

[0046] Furthermore, considering that indoor air and / or fresh air flow enters the second column housing from the bottom of the second column housing, the air flow in the middle or upper portion of the second air outlet may be smaller. Therefore, the present invention particularly provides a plurality of vertically arranged guide vanes in the second column housing, and the distance between the front and rear ends of the guide vanes located further up the column housing increases, so that the air flow at all vertical locations of the second air outlet is more uniform.

[0064] The present invention provides a vertical air conditioner indoor unit. This unit is the indoor portion of a split-type air conditioner and is used to condition the indoor air, such as for cooling / heating, dehumidification, and fresh air introduction. The vertical air conditioner indoor unit can be a conventional floor-standing cabinet unit or a vertical wall-mounted unit.

[0065] Figure 1 is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention, with reference to Figures 2 to 6 The vertical air-conditioning indoor unit of the embodiment of the present invention includes a first column housing 10, a second column housing 20 and a third column housing 30.

[0066] The first column housing 10 is in the shape of a vertical column, and a first air outlet 11 is provided on the front side of the first column housing 10 for blowing out a first air flow. The second column housing 20 is in the shape of a vertical column, and a second air outlet 21 is provided on the front side of the second column housing 20 for blowing out a second air flow. The third column housing 30 is in the shape of a vertical column, and a third air outlet 31 is provided on the front side of the third column housing 30 for blowing out a third air flow.

[0067] The third column housing 30 is located directly above the second column housing 20 , and the third air outlet 31 is located directly above the second air outlet 21 . The second column housing 20 and the first column housing 10 are arranged in a transverse direction, and the first column housing 10 is higher than the second column housing 20 .

[0068] The vertical air conditioning indoor unit of the present invention includes a long first column housing 10 and two short second column housings 20 and a third column housing 30, wherein the third column housing 30 is located above the second column housing 20. The first column housing 10, the second column housing 20, and the third column housing 30 respectively have independent first air outlets 11, second air outlets 21, and third air outlets 31. The first column housing 10, the second column housing 20, and the third column housing 30 blow out the airflow introduced into them, and the air can be discharged in multiple directions simultaneously through the setting of the air outlet directions of the first air outlet 11, the second air outlet 21, and the third air outlet 31, thereby meeting the needs of multiple users in the same indoor space for multiple air supply angles of the vertical air conditioning indoor unit. The first column housing 10, the second column housing 20, and the third column housing 30 can also independently supply air to one or two of them according to the needs of the user. In particular, when the air outlet angles of the second air outlet 21 and the first air outlet 11 are consistent, the air outlet airflows of the second air outlet 21 and the first air outlet 11 can be mixed in front of the second air outlet 21 and the first air outlet 11 and then blown out. When the air outlet angles of the third air outlet 31 and the first air outlet 11 are consistent, the air outlet airflows of the third air outlet 31 and the first air outlet 11 can be mixed in front of the third air outlet 31 and the first air outlet 11 and then blown out, thereby making the airflow blown out by the vertical air-conditioning indoor unit softer and more comfortable.

[0069] In some embodiments of the present invention, the ratio of the width of the second column housing 20 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 of the second column housing 20 in the front-to-back direction to the depth of the first column housing 10 in the front-to-back 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 shape of a vertical bar, the second air outlet 21 is in the shape of a vertical bar, and the third air outlet 31 is in the shape of a vertical bar. The above arrangement allows the second air outlet 21 and the third air outlet 31 to be flush or substantially flush with the front-to-back position of the first air outlet 11, so that the airflow from the second air outlet 21, the third air outlet 31 and the first air outlet 11 can be better mixed. The second column housing 20 and the third column housing 30 are significantly smaller than the first column housing 10, forming large and small columns spaced apart, which is very unique in appearance and enhances the decorative properties of the household air conditioner.

[0070] In some embodiments of the present invention, the cross-sectional profile of the third column housing 30 is consistent with that of the second column housing 20 , and the third column housing 30 and the second column housing 20 are integrally formed, which saves costs and facilitates installation.

[0071] In some embodiments of the present invention, the vertical air conditioner indoor unit further includes a heat exchanger 14 , a heat exchange fan 15 , a cross-flow fan 34 , a lower shell 40 , and a second airflow fan 41 .

[0072] The rear wall and rear portions of both side walls of the first column housing 10 are each provided with a first air inlet 13 that communicates with the first air outlet 11. The first air inlet 13 communicates with the indoor space. A heat exchanger 14 and a heat exchange fan 15 are provided within the first column housing 10. The heat exchange fan 15 encourages indoor air to enter the first column housing 10 through the first air inlet 13. The indoor air then flows through the heat exchanger 14 and out of the first air outlet 11 of the first column housing 10.

[0073] A third air inlet 33, which communicates with the third air outlet 31, is provided on both the rear portion of the sidewall of the third column housing 30, away from the first column housing 10, and on the rear wall of the third column housing 30. The first air inlet 13 is located behind the third air inlet 33. The third air inlet 33 communicates with the indoor space, and a crossflow fan 34 is provided within the third column housing 30. The crossflow fan 34 encourages indoor air to enter the third column housing 10 through the third air inlet 33 and to flow out of the first air outlet 11 of the first column housing 10.

[0074] The lower end of the second column housing 20 is provided with a second air inlet 23 that communicates with the second air outlet 21. The lower housing 40 is provided below the second column housing 20. The second air inlet 23 communicates with the air outlet of a second air flow fan 41 provided in the lower housing 40. The second air flow fan 41 is used to force the second air flow into the second column housing 20 and out of the second air outlet.

[0075] In some embodiments of the present invention, a first air induction gap 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 discharges air, the air in the first air induction gap 16 is driven forward by the negative pressure to mix with the outlet air flow of the second column shell 20 and / or the first column shell 10, forming an induction mixed air effect. The mixed air flow is more comfortable, the wind feels softer, and the air volume and wind speed are increased, and the air supply distance is longer.

[0076] A second air-inducing interval 26 is formed between the third column shell 30 and the first column shell 10, so that when air is discharged from the first air outlet 11 and / or the third air outlet 31, the air in the second air-inducing interval 26 is driven forward by the negative pressure to mix with the outlet air flow of the third column shell 30 and / or the first column shell 10, forming an air-inducing mixed air effect. The mixed air flow is more comfortable, the wind feels softer, the air volume and wind speed are increased, and the air supply distance is longer.

[0077] The distance between the two sidewalls of the second column housing 20 gradually decreases from back to front, forming a tapered shape, thereby increasing the wind speed out of the second air outlet 21 and facilitating air delivery to distant locations. The distance between the two sidewalls of the third column housing 30 gradually decreases from back to front, forming a tapered shape, thereby increasing the wind speed out of the third air outlet 31 and facilitating air delivery to distant locations. Both the first air induction gap 16 and the second air induction gap 26 have a gradually expanding shape, with the lateral dimension gradually increasing from back to front.

[0078] In some embodiments of the present invention, the first air outlet 11, the second air outlet 21, and the third air outlet 31 are all vertical strips. The vertical air conditioner indoor unit further includes: two first air guide plate groups, a second air guide plate group, and a third air guide plate group.

[0079] Two first air deflector groups are arranged sequentially from top to bottom at the first air outlet 11. Each first air deflector group includes multiple first air deflectors 12. The multiple first air deflectors 12 are arranged sequentially along the horizontal direction of the first air outlet 11, and each first air deflector 12 is rotatable about a vertical axis. The two air deflector groups divide the first air outlet 11 into two upper and lower air outlet sections. The two air deflector groups can rotate only in the same direction or can be configured to rotate independently. In other words, the two air outlet sections can blow air in only one direction at a time or discharge air in two directions separately.

[0080] The second air deflector group is disposed at the second air outlet 21. The second air deflector group includes a plurality of second air deflectors 22. The plurality of second air deflectors 22 are sequentially disposed horizontally along the second air outlet 21. Each second air deflector 22 is rotatably disposed about a vertical axis. The second air deflectors 22 are used to guide wind laterally. The third air deflector group is disposed at the third air outlet 31. The third air deflector group includes a plurality of third air deflectors 32. The plurality of third air deflectors 32 are sequentially disposed horizontally along the third air outlet 31. Each third air deflector 32 is rotatably disposed about a vertical axis. The third air deflectors 32 are used to guide wind laterally. The first air deflector group on the lower side corresponds to the second air deflector group in the vertical direction. The first air deflector group on the upper side corresponds to the third air deflector group in the vertical direction.

[0081] The above arrangement enables the vertical air conditioner indoor unit to have a more diverse and multi-angle air supply. The first air outlet 11, the second air outlet 21, and the third air outlet 31 can each supply air at different angles, or can cooperate to supply air in one or two directions. For example, the air outlet section on the upper side of the first air outlet 11 discharges air to the left, the air outlet section on the lower side of the first air outlet 11 discharges air to the right, the second air outlet 21 can discharge air at various angles in the left, front, and right directions, and the third air outlet 31 can discharge air at various angles in the left, front, and right directions. For another example, the air outlet section of the upper first air outlet 11 discharges air to the left, the air outlet section of the lower first air outlet 11 discharges air to the right, the second air outlet 21 can discharge air to the left, and the third air outlet 31 can discharge air to the right.

[0082] In some embodiments of the present invention, Figure 2 and Figure 4As shown, the side wall of the lower housing 40 is provided with a fresh air inlet 43 and at least one indoor air inlet 44, which are connected to the air inlet of the second air flow fan 41. The vertical air conditioner indoor unit also includes a valve configured to controllably connect one of the fresh air inlet 43 and the indoor air inlet 44 to the air inlet of the second air flow fan 41.

[0083] The above arrangement enables the second air flow blower 41 to introduce fresh air and / or indoor air in a controlled manner. A fresh air duct is connected to the fresh air inlet 43 to introduce fresh air from the outside. The fresh air inlet 43 is located on the rear wall of the lower shell 40, and there are two indoor air inlets 44, one on each of the two lateral walls of the lower shell 40. This arrangement enables the second air flow blower 41 to draw in both fresh air and indoor air, achieving a two-pronged effect. Furthermore, a valve can be provided at the fresh air inlet 43 or the indoor air inlet 44 to control its opening or opening degree, thereby adjusting the intake ratio of the fresh air flow to the indoor air.

[0084] In some embodiments of the present invention, in order to detect the indoor air quality, a sensor is set at a suitable position inside the indoor unit of the vertical air conditioner that is in contact with the 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 housing 20 needs to introduce clean fresh air. When the sensor measures that the humidity of the indoor air is low, the second column housing 20 needs to introduce humidified indoor air. In order to meet the user's requirements for indoor air quality, a functional module 42 is provided 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. This functional module 42 can be a purification module and / or a humidification module.

[0085] In some embodiments of the present invention, Figure 4 As shown, a vertical strip-shaped air duct connected to the second air outlet 21 is provided in the second column housing 20, and the lower end of the air duct is its air inlet. A plurality of guide vanes 25 arranged vertically are provided in the air duct. Each guide vane 25 extends from front to back, and the rear end is bent downward to form a guide bend 251. The closer the guide vane 25 is to the top, the greater the distance between the front and rear ends. The second airflow flows from bottom to top, and after encountering each guide vane 25, it is guided by its guide bend 251, gradually changing from upward flow to forward flow. The guide bend 251 plays the role of changing the direction of the airflow, making the turning of the airflow smoother and the wind loss smaller. The guide bend 251 and the rest of the guide vane 25 are transitioned with a rounded corner.

[0086] Furthermore, considering that the second airflow enters the second column housing 20 from the bottom of the second column housing 20, this may result in a smaller airflow volume in the middle or upper portion of the second air outlet 21. Therefore, the embodiment of the present invention specifically provides a plurality of vertically arranged guide vanes 25 within the second column housing 20, and the guide vanes 25 positioned higher up have a greater distance between their front and rear ends, thereby making the airflow from the second air outlet 21 more uniform vertically. Of course, the smaller airflow volume in the middle or upper portion of the second air outlet 21 can also be fully utilized to reduce the air mixing effect on the upper side, thereby delivering air to areas where cooling is required, i.e., to areas where soft air is not required.

[0087] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, to expand the air supply angle of the vertical air conditioner indoor unit, the second column housing 20 and the third column housing 30 are configured to rotate independently. The second column housing 20 rotates about a first rotation axis vertically disposed therein. The third column housing 30 rotates about a second rotation axis vertically disposed therein. The first and second rotation axes are coaxial. The second and third column housings 20 and 30 rotate independently, allowing for a wide rotation angle, allowing the vertical air conditioner indoor unit to meet air supply requirements for all areas of the room.

[0088] In some embodiments of the present invention, at least one of the first, second, and third airflows is different from the others. Preferably, the second and third airflows are different; the first and third airflows are the same or different; or the first and second airflows are the same or different. The first airflow is a heat exchange airflow; the second airflow is indoor air, fresh air, purified air, humidified airflow, or water-washed airflow; and the third airflow is indoor air, fresh air, purified air, humidified airflow, or water-washed airflow. The inconsistency between the second and third airflows can resolve the issue of single soft air supply.

[0089] In some embodiments of the present invention, the second column housing 20 and / or the third column housing 30 are mounted with air guides for directing the lateral outflow direction of the second air outlet 21 and / or the third air outlet 31. "Directing the lateral outflow direction" refers to changing the angle between the outflow direction and the front-to-back direction, for example, directing the outflow toward the front, left, or right. Furthermore, the first column housing 10 is mounted with a first air guide plate 12 for directing the lateral outflow direction of the first air outlet 11.

[0090] like Figures 9 to 12 As shown, taking the second column housing 20 as an example, the vertical air conditioner indoor unit can be configured as follows: the wind guide 27 is used to adjust the horizontal air flow direction of the second air outlet 21 so that the second air flow can merge into the first air flow of the first air outlet 11. That is, when the first air guide plate 12 changes the air flow direction of the first air flow, the wind guide 27 is controlled to operate to ensure that the second air flow can always merge into the heat exchange air flow. Figure 9As shown, when the first wind guide plate 12 swings forward, the wind guide member 27 guides the wind forward. Figure 11 As shown, when the first wind guide plate 12 swings to the left, the wind guide member 27 guides the wind to the left. Figure 12 As shown, when the first air guide plate 12 swings to the right, the air guide member 27 is directed to the right. The main control board of the air conditioner can be electrically connected to the motors of the air guide member 27 and the first air guide plate 12 at the same time to control the coordinated action of the two.

[0091] In some embodiments of the present invention, a first clearance groove 2812 and a first slide groove 2811 communicating with the first clearance groove 2812 are provided on one side wall 281 of the air duct, a second clearance groove 2821 is provided on the other side wall 282 of the air duct, and the first plate 271 is slidably mounted on the first slide groove 2811. Figure 10 As shown, the air guide 27 may include a first plate 271 and a second plate 272 arranged in a transversely spaced arrangement. Of course, the second plate 272 and the first plate 271 are connected by other structures. Figure 10 The first plate 271 has a rearwardly bent portion 2711 at its end near the second plate 272. The bent portion 2711 and the second plate 272 define an air guide channel 270 with a gradually decreasing spacing from rear to front. The air guide 27 is rotatably mounted on the second column housing 20 about a vertical axis, allowing the lateral airflow direction of the second air outlet 21 to be varied by adjusting the relative position of the air guide channel 270 and the second air outlet 21.

[0092] For example Figure 9 and Figure 10 As shown, when the air guide channel 270 faces the second air outlet 21, the non-heat exchange air flow is guided to blow out toward the front. Figure 11 As shown, the air guide 27 is relatively Figure 9 The state is rotated clockwise so that the air guide channel 270 faces the left front, so as to guide the second air flow to blow out toward the left front. Figure 12 As shown, the air guide 27 is relatively Figure 9 The structure of the air guide member 27 of this embodiment is very simple and occupies very little space, and is particularly suitable for narrow air outlets such as the second air outlet 21. The design is very clever.

[0093] In some embodiments of the present invention, the air guide 27 can be rotated to a first position and a second position. When the air guide 27 is in the first position, the first bent portion 2711 is embedded in the first clearance groove 2812, and the air guide surface of the bent portion 2711 of the air guide 27 is located on a plane formed by the rear edge of the opening of the first clearance groove 2812 and the vertical edge of the second air outlet 21 adjacent to the first clearance groove 2812. Figure 11 shown.

[0094] When the air guide 27 is in the second position, the second plate 272 is embedded in the second clearance groove 2821, and the air guide surface of the second plate 272 is located on the plane formed by the rear edge of the opening of the second clearance groove 2821 and the vertical edge of the second air outlet 21 adjacent to the second clearance groove 2821. Figure 12 shown.

[0095] In some embodiments of the present invention, the second air outlet 21 can be closed by an air guide 27. Similarly, a similar air guide 27 can also be provided at the third air outlet.

[0096] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
