Description

TECHNICAL FIELD

[0002] The appearance of the existing vertical air conditioner indoor unit is not obviously different, and the experience is not good according to the existing air supply mode, resulting in many complaints from users. When using the air conditioner to cool, users often encounter a group of contradictory problems: the air outlet temperature is low, the air speed is high, and it is not comfortable to blow on the body, that is, people often say that the wind is too "hard" and not soft enough. In combination with user pain points and industry development trends, the soft wind experience characteristics are proposed. Research has found that if a part of indoor air can be mixed into the cold air of the air conditioner, the temperature of the mixed air flow will rise by 1-3 degrees, and the feeling of blowing on the body will be more comfortable.

[0045] The indoor unit of the vertical air conditioner of the present application comprises a large first columnar shell and two small second and third columnar shells, the second and third columnar shells are located on both sides of the first columnar shell, forming a brand new three-column shell vertical air conditioner indoor unit. The first, second and third columnar shells have their own independent first, second and third air outlets respectively. The first columnar shell blows out heat exchange airflow, and the second and third columnar shells on both sides blow out indoor air or fresh air flow. The first, second and third columnar shells can send air separately, or simultaneously, or through the setting of the air outlet direction of the first, second and third air outlets, diversified multi-angle air supply can be realized. The first columnar shell and the second columnar shell form a first air induction interval, and the first columnar shell and the third columnar shell form a second air induction interval. In this way, when the first columnar shell and / or the third columnar shell blows air, a negative pressure environment is formed at the first air induction interval, prompting the indoor air behind the vertical air conditioner indoor unit to flow forward through the first air induction interval to mix into the air flow of the first columnar shell and / or the third columnar shell, forming an air induction and air mixing effect. The temperature of the mixed air flow is closer to room temperature than that of the heat exchange airflow, the comfort is higher, the wind feeling is softer, and the air volume and air speed are also increased, and the air supply distance is farther. When the first columnar shell and / or the second columnar shell blows air, the same effect as above is also achieved. In particular, when the second, third and first air outlets have the same air outlet direction, the air outlets of the second, third and first air outlets and the indoor air flowing forward in the first and second air induction intervals can be mixed in front to form mixed air. The air volume and air speed of the mixed air are increased, and the air supply distance is farther. That is, the air conditioner soft wind mixing effect is very good.

[0046] Further, the second and third columnar shells blow out fresh air flow, purification flow, humidification flow or water washing flow, etc. Adjusting airflow, so that these adjusting airflows can be more mixed with heat exchange airflow, increase the mixing rate, and make it better diffuse to various places in the room. A variety of types of soft wind can be formed, solving the problem of single type of air conditioner soft wind air supply.

[0047] Further, considering that the indoor air and / or fresh air flow enters the second and third columnar shells from the bottom of the second and third columnar shells, it may cause the air volume of the middle or upper part of the second and third air outlets to be small. Therefore, the present application specially sets a plurality of vertically arranged guide vanes in the second columnar 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.

[0065] 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, used to adjust indoor air, such as refrigeration / heating, 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.

[0066] Figure 1 is a schematic front view of the vertical air conditioner indoor unit of an embodiment of the present application, with reference to Figure 2 From 12, the vertical air conditioner indoor unit of the embodiments of the present application includes a first column shell 10, a second column shell 20 and a third column shell 30.

[0067] 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.

[0068] The second column shell 20 and the third column shell 30 are arranged on the two sides of the first column shell 10 in the transverse direction. The first air guiding interval 16 is formed between the second column shell 20 and the first column shell 10, so that the air in the first air guiding interval 16 is driven to flow forward by the negative pressure when the first air outlet 11 and / or the second air outlet 21 blows air. The second air guiding interval 26 is formed between the third column shell 30 and the first column shell 10, so that the air in the second air guiding interval 26 is driven to flow forward by the negative pressure when the first air outlet 11 and / or the third air outlet 31 blows air.

[0069] The vertical air conditioner indoor unit of the present application comprises a large first column shell 10 and two small second column shell 20 and third column shell 30, which are arranged on the two sides of the first column shell 10, forming a large and two small new three-column shell vertical air conditioner indoor unit. The first column shell 10, the second column shell 20 and the third column shell 30 have their own independent first air outlet 11, second air outlet 21 and third air outlet 31 respectively. The first column shell 10 blows heat exchange air flow, and the two side second column shell 20 and third column shell 30 blow indoor air or fresh air flow. The first column shell 10, the second column shell 20 and the third column shell 30 can blow air separately, or can blow air at the same time, or can realize diversified and multi-angle air supply through the setting of the air outlet direction of the first air outlet 11, the second air outlet 21 and the third air outlet 31. For example, the first column shell 10 blows air alone or the second column shell 20 blows air alone or the third column shell 30 blows air alone. For another example, the first column shell 10 blows air forward, the second column shell 20 blows air left, and the third column shell 30 blows air right.

[0070] The first air guiding interval 16 is formed between the first column shell 10 and the second column shell 20, and the second air guiding interval 26 is formed between the first column shell 10 and the third column shell 30. In this way, when the first column shell 10 and / or the third column shell 30 blows air, a negative pressure environment is formed at the first air guiding interval 16, which promotes the indoor air behind the vertical air conditioner indoor unit to flow forward through the first air guiding interval 16, so as to mix into the air flow of the first column shell 10 and / or the third column shell 30, forming a guiding and mixing air effect. The temperature of the mixed air flow is closer to the room temperature than that of the heat exchange air flow, the comfort is higher, the wind feeling is more soft, and the air volume and air speed are increased, so the air supply distance is farther. When the first column shell 10 and / or the second column shell 20 blows air, the same effect as above is also achieved. In particular, the air outlet directions of the second air outlet 21, the third air outlet 31 and the first air outlet 11 are consistent, so that the air blown out of the second air outlet 21, the third air outlet 31 and the first air outlet 11 and the indoor air flowing forward in the first air guiding interval 16 and the second air guiding interval 26 are mixed in front, forming mixed air. The air volume and air speed of the mixed air are increased, and the air supply distance is farther. That is, the air conditioner soft air mixing effect is very good.

[0071] In some embodiments of the present application, the ratio of the width of the second column shell 20 in the lateral direction to the width of the first column shell 10 in the lateral direction is less than 1 / 2. The ratio of the longitudinal dimension of the second column shell 20 in the front-rear direction to the longitudinal dimension 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 lateral direction. The ratio of the width of the third column shell 30 in the lateral direction to the width of the first column shell 10 in the lateral direction is less than 1 / 2. The ratio of the longitudinal dimension of the third column shell 30 in the front-rear direction to the longitudinal dimension of the first column shell 10 in the front-rear direction is less than 1 / 2. The first air outlet 11 and the third air outlet 31 are arranged in the lateral direction.

[0072] 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 and the third air outlet 31 and the first air outlet 11 are better mixed. The second column shell 20 and the third column shell 30 are obviously smaller than the first column shell 10, forming two small and one large column shells arranged in intervals, which are stable and distinctive in appearance, and enhance the decorative properties of the household air conditioner. In some alternative embodiments of the present application, only one of the second column shell 20 and the third column shell 30 can be small.

[0073] In some embodiments of the present application, the two side walls of the first column shell 10 are symmetrically arranged about a vertical reference plane extending in the front-rear direction. The cross-sectional profiles of the second column shell 20 and the third column shell 30 are symmetrically arranged about the vertical reference plane, so that the first air induction interval 16 and the second air induction interval 26 are symmetrically arranged.

[0074] The symmetric arrangement can make the mixed air formed by the air flows from the second air outlet 21 and the third air outlet 31 and the first air outlet 11 and the indoor air flowing forward in the first air induction interval 16 and the second air induction interval 26 more uniform, and the air induction and air mixing effect is better. Moreover, the three column shells symmetrically arranged about the vertical reference plane extending in the front-rear direction also conform to the aesthetic view of Chinese people.

[0075] In some embodiments of the present application, the distance between the two side walls of the second column shell 20 gradually decreases from rear to front, forming a tapered shape. The tapered shape increases the air speed of the second air outlet 21, which is beneficial to sending air to a distance. The first air induction interval 16 is gradually expanded in the lateral direction from rear to front.

[0076] The distance between the two side walls of the third column shell 30 gradually decreases from rear to front, forming a tapered shape. The tapered shape increases the air speed of the second air outlet 21, which is beneficial to sending air to a distance. The second air induction interval 26 is gradually expanded in the lateral direction from rear to front.

[0077] In some embodiments of the present application, the indoor unit of the upright air conditioner further comprises a lower shell 40, a heat exchanger 14, a heat exchanger fan 15, an air induction mechanism 41, and a valve.

[0078] The rear wall and the rear portions of the two side walls of the first column shell 10 are provided with a first air inlet 13 which is in communication with the first air outlet 11. The first air inlet 13 is in communication with the indoor space. A heat exchanger 14 and a heat exchanger fan 15 are arranged in the first column shell 10. The heat exchanger 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. The first air inlet 13 is integrally formed with the first column shell 10, which saves installation space and also makes the manufacturing cost of the indoor unit of the vertical air conditioner lower. The lower shell is arranged below the second column shell 20 and the third column shell 30. The lower shell serves as the foundation for supporting the second column shell 20 and the third column shell 30, and also provides space for arranging the air guide mechanism 41.

[0079] The air guide mechanism 41 arranged in the lower shell 40 is used to transport non-heat exchange air flow to the second column shell 20 and the third column shell 30.

[0080] The lower shell side wall is provided with a fresh air inlet 43 and at least one indoor air inlet 44 which are in communication with the air inlet of the air guide mechanism 41. The fresh air inlet 43 is connected with a fresh air pipe to introduce fresh air flow from the outdoor. The fresh air inlet 43 is located on the rear wall of the lower shell 40, and the number of indoor air inlets 44 is two, which are respectively located on the two side walls of the lower shell 40. The air guide mechanism 41 introduces fresh air and indoor air through the fresh air inlet 43 and the indoor air inlet 44 respectively. This arrangement enables the air guide mechanism 41 to suck in fresh air flow and indoor air, achieving a one-stroke two-effect. The air outlet of the air guide mechanism 41 is in communication with the second air inlet 23 arranged at the lower end of the second column shell 20 and the third air inlet 33 arranged at the lower end of the third column shell 30 through a "Y"-shaped flow distribution mechanism. The second column shell 20 and the third column shell 30 blow out the fresh air and / or indoor air entering them from their corresponding second air outlet 21 and third air outlet 31 under the action of the air guide mechanism 41 arranged below. Of course, valves can be arranged between the fresh air inlet 43 and the air inlet of the air guide mechanism 41 and between the indoor air inlet 44 of the lower shell 40 and the air inlet of the air guide mechanism 41. The valves are configured to controllably communicate the fresh air inlet 43 or all the indoor air inlets 44 with the air inlet of the air guide mechanism 41. This arrangement enables the second column shell 20 and the third column shell 30 to controllably blow out fresh air and / or indoor air.

[0081] In some embodiments of the present application, in order to detect the indoor air quality, sensors are arranged at appropriate positions inside the vertical air conditioner indoor unit which are in contact with indoor air to monitor the indoor air quality in real time. When the sensors detect that the oxygen content of the indoor air is low, the second column shell 20 can selectively introduce clean fresh air, and when the sensors detect that the humidity of the indoor air is low, the second column shell 20 can selectively introduce humidified indoor air. In order to meet the requirements of users for indoor air quality, a functional module 42 is arranged at the air inlet of the air induction mechanism 41, so that the air entering the air inlet of the air induction mechanism 41 first passes through the functional module 42. This functional module 42 can be a purification module and / or a humidification module.

[0082] In some embodiments of the present application, the first air outlet is in the shape of a vertical strip. The second air outlet 21 is in the shape of a vertical strip, and the second column shell 20 is provided with a vertical strip-shaped first air duct 28 communicating with the second air outlet 21. The airflow entering the first air duct 28 is the first airflow.

[0083] The first air duct 28 is provided with a plurality of first guide vanes 25 arranged in the vertical direction. Each first guide vane 25 extends from front to back, and the rear end is bent downward to form a first guide bending portion 251. The distance between the front and rear ends of the first guide vane 25 located higher is greater.

[0084] The first airflow flows from bottom to top, and after encountering each first guide vane 25, it is guided by the first guide bending portion 251 and gradually changes from upward flow to forward flow. Therefore, the first guide bending portion 251 changes the direction of the airflow, making the turning of the airflow more gentle and the wind power loss smaller. The first guide bending portion 251 and the rest of the first guide vane 25 are connected by a rounded corner.

[0085] Further, considering that the first airflow enters the second column shell 20 from the bottom of the second column shell 20, it can cause the air outlet of the middle or upper part of the second air outlet 21 to be smaller. Therefore, the embodiments of the present application are particularly provided with a plurality of first guide vanes 25 arranged in the vertical direction in the second column shell 20, and the distance between the front and rear ends of the first 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 of the middle or upper part of the second air outlet 21 is smaller can also be fully utilized, so that the air mixing effect on the upper side is poor, and the air can be sent to the place where cold air is needed, i.e. to the place where soft air is not needed.

[0086] The third air outlet 31 is vertically shaped, and a vertically shaped second air duct is provided inside the third column housing 30, connecting to the third air outlet 31. The airflow entering the second air duct is called the second airflow. Multiple second guide vanes are arranged vertically within the second air duct. Each second guide vane extends from front to back, with its rear end bent downwards to form a second guide bend. The distance between the front and rear ends of the second guide vane located higher up is greater. The second airflow flows from bottom to top, and upon encountering each second guide vane, it is guided by its second guide bend, gradually changing from upward flow to forward flow. Therefore, the second guide bend changes the direction of the airflow, making the airflow change more gently and reducing wind loss. The second guide bend transitions to the rest of the second guide vane with a rounded corner.

[0087] Furthermore, considering that the second airflow enters the third column housing 30 from the bottom, it may cause the airflow volume in the middle or upper part of the third air outlet 31 to be relatively small. Therefore, in this embodiment of the invention, multiple vertically arranged second guide vanes are specifically provided inside the third column housing 30, and the distance between the front and rear ends of the second guide vanes located higher up is larger, making the airflow from the third air outlet 31 more uniform in all vertical locations. Of course, the problem of the relatively small airflow volume in the middle or upper part of the third air outlet 31 can also be fully utilized, resulting in poor air mixing effect on the upper side, so that air can be delivered to places that require cooling, that is, to places that do not require soft air.

[0088] 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.

[0089] like Figures 7 to 10 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 first airflow to converge into the heat exchange airflow of the first air outlet 11. That is, when the first air guide plate 12 changes the airflow direction of the heat exchange airflow, the air guide 27 is controlled to operate, ensuring that the first airflow always converges into the heat exchange airflow. For example... Figure 7 As shown, when the first air guide plate 12 swings forward, it causes the air guide component 27 to guide the air forward. Figure 9 As shown, when the first air guide plate 12 swings to the left, it causes the air guide component 27 to guide the air to the left. Figure 10 As shown, when the first air guide plate 12 swings to the right, it causes the air guide component 27 to guide the air to the right. The main control board of the air conditioner can be electrically connected to the motors of both the air guide component 27 and the first air guide plate 12 to control their coordinated operation.

Figure 8 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 guiding passage 270 with a gradually decreasing distance from rear to front. The air guiding member 27 is rotatably installed around a vertical axis on the second columnar shell 20, so as to change the transverse air outlet direction of the second air outlet 21 by adjusting the relative position between the air guiding passage 270 and the second air outlet 21. Figure 8 As shown in the figure, when the air guiding passage 270 is opposite to the second air outlet 21, the first air flow is guided to blow forward. As shown in the figure, the air guiding member 27 is rotated clockwise relative to the

[0091] As shown in the figure, the air guiding member 27 is rotated counterclockwise relative to the Figure 7 state, so that the air guiding passage 270 is directed to the left front, so as to guide the second air flow to blow to the right front. The structure of the air guiding member 27 of the present embodiment is very simple, and occupies a very small space, and is particularly suitable for the second air outlet 21 with a thin and narrow shape, and is very ingenious in design.
