Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a vertical air conditioner indoor unit. Background Technology

[0002] Existing floor-standing air conditioners lack significant visual differences, and their current airflow methods result in a poor user experience, leading to numerous complaints. Users often encounter a contradictory problem when using air conditioning for cooling: low outlet temperature, high fan speed, and uncomfortable airflow – what people commonly refer to as "harsh" and not gentle enough. Based on user pain points and industry trends, a softer airflow feature is proposed. Research has found that mixing some indoor or outdoor air into the air conditioner's cool air raises the airflow temperature by 1-2 degrees Celsius, resulting in a softer and more comfortable feel. Furthermore, existing floor-standing units mostly offer a single-function airflow, failing to meet the diverse needs of users. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide a vertical air conditioner indoor unit that overcomes or at least partially solves the above problems, can solve the problems of air conditioning blowing too "hard" and single air supply function, can provide multiple soft air delivery modes, and bring users a more comfortable air supply experience.

[0004] Specifically, the present invention provides a vertical air conditioner indoor unit, comprising:

[0005] The first column shell is in the shape of a vertical column, and a first air outlet is provided on the front side of the first column shell for blowing out the first airflow.

[0006] The second column shell is in the shape of a vertical column, and a second air outlet is provided on the front side of the second column shell for blowing out a second airflow.

[0007] The third column shell is in the shape of a vertical column, and a third air outlet is provided on the front side of the third column shell for blowing out a third airflow.

[0008] The second and third columnar shells are arranged laterally on both sides of the first columnar shell, and the first, second, and third airflows are different from each other.

[0009] Optionally, the first airflow, the second airflow, and the third airflow are three of the following: heat exchange airflow, indoor air, fresh air airflow, purified airflow, humidified airflow, and water washing airflow.

[0010] Optionally, the second column shell and the first column shell form a first air-guiding interval, so that when the first air outlet and / or the second air outlet discharge air, the air in the first air-guiding interval is driven forward by the negative pressure; the third column shell and the first column shell form a second air-guiding interval, so that when the first air outlet and / or the third air outlet discharge air, the air in the second air-guiding interval is driven forward by the negative pressure.

[0011] Both the first and second air-expanding intervals are gradually expanding in lateral dimension from back to front.

[0012] Optionally, the ratio of the width of the second column shell in the lateral direction to the width of the first column shell in the lateral direction is less than 1 / 2; the ratio of the depth dimension of the second column shell in the front-to-back direction to the depth dimension of the first column shell in the front-to-back direction is less than 1 / 2; and the first air outlet and the second air outlet are arranged in the lateral direction.

[0013] The ratio of the width of the third column shell in the lateral direction to the width of the first column shell in the lateral direction is less than 1 / 2; the ratio of the depth dimension of the third column shell in the front-to-back direction to the depth dimension of the first column shell in the front-to-back direction is less than 1 / 2; and the first air outlet and the third air outlet are arranged in the lateral direction.

[0014] The first air outlet is in the shape of a vertical strip, the second air outlet is in the shape of a vertical strip, and the third air outlet is in the shape of a vertical strip.

[0015] Optionally, the rear wall of the first column shell and the rear of the two side walls are each provided with a first air inlet that communicates with the first air outlet.

[0016] The second column shell is provided with a second air inlet on the rear part of the side wall away from the first column shell and on the rear wall of the second column shell, which communicates with the second air outlet; the first air inlet is located behind the second air inlet.

[0017] The lower end of the third column housing is provided with a third air inlet that communicates with the third air outlet.

[0018] Optionally, the indoor unit of the floor-standing air conditioner also includes:

[0019] A cross-flow fan, wherein the cross-flow fan is vertically installed inside the second column shell;

[0020] The lower shell is disposed below the third columnar shell;

[0021] An exhaust fan is disposed inside the lower shell to introduce the third airflow into the third column shell; a heat exchanger and a heat exchange fan are disposed inside the first column shell to make the first airflow a heat exchange airflow.

[0022] Optionally, a fourth air inlet is provided on the rear side wall of the lower shell, and the fourth air inlet is connected to the air inlet of the induced draft fan;

[0023] The fourth air inlet is an outdoor fresh air inlet;

[0024] A functional module is provided between the fourth air inlet and the air inlet of the exhaust fan; the functional module is a purification module and / or a humidification module.

[0025] Optionally, the third column housing is provided with an air duct that connects to the third air outlet;

[0026] The air duct is provided with multiple guide vanes arranged vertically. Each guide vane extends from front to back and its rear end bends downward to form a guide bend. The distance between the front and rear ends of the guide vane is greater the higher the position of the bend.

[0027] Optionally, the distance between the two side walls of the second cylindrical shell gradually decreases from back to front, forming a tapering shape;

[0028] The distance between the two side walls of the third column shell gradually decreases from back to front, forming a tapering shape.

[0029] Optionally, the two sidewalls of the first column shell are symmetrically arranged about a vertically extending reference plane; the cross-sectional profiles of the second and third column shells are symmetrically arranged about the vertical reference plane, so that the first air intake interval and the second air intake interval are symmetrically arranged.

[0030] The vertical air conditioner indoor unit of this invention includes a large first column housing and two smaller second and third column housings. The second and third column housings are located on both sides of the first column housing, forming a novel three-column vertical air conditioner indoor unit. Each of the first, second, and third column housings has its own independent first, second, and third air outlets. The first, second, and third air outlets respectively blow out a first airflow, a second airflow, and a third airflow. The first, second, and third airflows can be any of the following: heat exchange airflow, indoor airflow, fresh airflow, purified airflow, humidifying airflow, and water washing airflow, and each of the first, second, and third airflows is different. For example, the first column housing blows out a heat exchange airflow, while the two second and third column housings blow out indoor air and fresh airflow respectively. The first, second, and third column housings can supply air individually or simultaneously, and the airflow direction of the first, second, and third air outlets can be configured to achieve diverse and multi-angle air supply. For example, the first, second, and third column shells supply air simultaneously, and the air outlet directions are consistent. The three airflows mix in front, the temperature of the mixed airflow is moderate, the mixed air volume and wind speed are greater, and the air is delivered further.

[0031] Furthermore, a first air-drawing interval is formed between the first and second column housings, and a second air-drawing interval is formed between the first and third column housings. Thus, when air exits from the first and / or third column housings, a negative pressure environment is created at the first air-drawing interval, causing indoor air behind the vertical air conditioner's indoor unit to flow forward through the first air-drawing interval, mixing with the airflow from the first and / or third column housings, creating a mixed airflow effect. The temperature of the mixed airflow is closer to room temperature than the heat exchange airflow, resulting in higher comfort, a gentler breeze, increased airflow volume and velocity, and a longer delivery distance. The same effect occurs when air exits from the first and / or second column housings. In particular, when the second, third, and first air outlets have the same airflow direction, the airflow from the second, third, and first air outlets, along with the forward-flowing indoor air within the first and second air-drawing intervals, can be mixed in front, forming a mixed airflow. The mixed airflow volume and velocity increase, and the delivery distance is further increased.

[0032] Furthermore, the second and third column shells blow out indoor air, fresh air, purified air, humidified air or water washing air, etc., so that these regulated airflows can mix with the heat exchange airflow earlier and more, enhance the mixing rate, and make them diffuse better to all parts of the room.

[0033] Furthermore, considering that the fresh airflow enters the third column housing from the bottom, it may cause the airflow volume in the middle or upper part of the third air outlet to be relatively small. Therefore, the present invention specifically provides multiple vertically arranged guide vanes inside the third column housing, and the distance between the front and rear ends of the guide vanes located higher up is larger, so that the airflow from the third air outlet is more uniform in all vertical directions.

[0034] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

Those skilled in the art should be able to understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] This invention provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor section of a split-type air conditioner, used to regulate indoor air, such as cooling / heating, dehumidifying, and introducing fresh air. The vertical air conditioner indoor unit can be a conventional floor-standing unit or a vertical wall-mounted unit.

[0053] Figure 1 This is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention, with reference to... Figure 2 Up to 13, the vertical air conditioner indoor unit of this embodiment includes a first column housing 10, a second column housing 20 and a third column housing 30.

[0054] The first column housing 10 is vertically columnar, and a first air outlet 11 for blowing out a first airflow is provided on the front side of the first column housing 10. The second column housing 20 is vertically columnar, and a second air outlet 21 for blowing out a second airflow is provided on the front side of the second column housing 20. The third column housing 30 is vertically columnar, and a third air outlet 31 for blowing out a third airflow is provided on the front side of the third column housing 30. The second column housing 20 and the third column housing 30 are arranged laterally on both sides of the first column housing 10, and the first airflow, the second airflow, and the third airflow are different from each other.

[0055] The vertical air conditioner indoor unit of the present invention includes a large first column housing 10 and two smaller second column housings 20 and a third column housing 30. The second column housings 20 and 30 are located on both sides of the first column housing 10, forming a novel three-column vertical air conditioner indoor unit with one large and two small columns. The first column housing 10, the second column housing 20, and the third column housing 30 each have their own independent first air outlet 11, second air outlet 21, and third air outlet 31. The first air outlet 11, the second air outlet 21, and the third air outlet 31 respectively blow out a first airflow, a second airflow, and a third airflow. The first airflow, the second airflow, and the third airflow can be any one of the following: heat exchange airflow, indoor airflow, fresh airflow, purified airflow, humidifying airflow, and water washing airflow, and the first airflow, the second airflow, and the third airflow are all different. For example, the first column housing 10 blows out a heat exchange airflow, while the two second column housings 20 and the third column housing 30 blow out indoor air and fresh airflow respectively. The first column housing 10, the second column housing 20, and the third column housing 30 can blow air individually or simultaneously. Furthermore, the airflow direction of the first air outlet 11, the second air outlet 21, and the third air outlet 31 can be configured to achieve diverse and multi-angle airflow. For example, when the first column housing 10, the second column housing 20, and the third column housing 30 blow air simultaneously in the same direction, the three airflows mix in front, resulting in a moderate temperature, greater airflow volume and velocity, and a longer airflow distance.

[0056] 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 air is discharged from the first air outlet 11 and / or the second air outlet 21, the air in the first air-guiding interval 16 is driven forward by the negative pressure. A second air-guiding 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-guiding interval 26 is driven forward by the negative pressure. Both the first air-guiding interval 16 and the second air-guiding interval 26 are gradually expanding in a lateral dimension that gradually increases from back to front.

[0057] Thus, when the first column housing 10 and / or the third column housing 30 discharges air, a negative pressure environment is created at the first air intake interval 16, causing the indoor air behind the vertical air conditioner indoor unit to flow forward through the first air intake interval 16, mixing with the airflow from the first column housing 10 and / or the third column housing 30, forming a mixed airflow effect. The temperature of the mixed airflow is closer to room temperature than the heat exchange airflow, resulting in higher comfort, a gentler breeze, increased air volume and velocity, and a longer delivery distance. The same effect occurs when the first column housing 10 and / or the second column housing 20 discharges air. In particular, the second air outlet 21, the third air outlet 31, and the first air outlet 11 discharge in the same direction, which can mix the airflow from the second air outlet 21, the third air outlet 31, and the first air outlet 11, as well as the forward-flowing indoor air within the first air intake interval 16 and the second air intake interval 26, forming mixed air. The mixed airflow has increased air volume and velocity, and a longer delivery distance.

[0058] In some embodiments of the present invention, the ratio of the width of the second column housing 20 in the lateral direction to the width of the first column housing 10 in the lateral 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 lateral direction. The ratio of the width of the third column housing 30 in the lateral direction to the width of the first column housing 10 in the lateral direction is less than 1 / 2. The ratio of the depth of the third column housing 30 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 third air outlet 31 are arranged in the lateral direction. The first air outlet 11, the second air outlet 21, and the third air outlet 31 are all vertical stripes.

[0059] The above arrangement allows the second air outlet 21 and the third air outlet 31 to be aligned or nearly aligned with the front and rear positions 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 shell 20 and the third column shell 30 are significantly smaller than the first column shell 10, forming a three-column shell with two smaller and one larger columns spaced apart. The appearance is stable and unique, enhancing the decorative attributes of the household air conditioner.

[0060] In some embodiments of the present invention, the rear wall and the rear portions of both side walls of the first column housing 10 are provided with a first air inlet 13 communicating with the first air outlet 11. The first air inlet 13 communicates with the indoor space. The rear portions of the side walls of the second column housing 20 away from the first column housing 10 and the rear wall of the second column housing 20 are both provided with a second air inlet 23 communicating with the second air outlet 21; the first air inlet 13 is located behind the second air inlet 23; the second air inlet 23 communicates with the indoor space. Corresponding to the relative position between the second column housing 20 and the first column housing 10, the first air inlet is located behind the second air inlet. The lower end of the third column housing is provided with a third air inlet communicating with the third air outlet.

[0061] In some embodiments of the present invention, the indoor unit of the vertical air conditioner further includes a lower casing 40, a heat exchanger 14, a heat exchange fan 15, and an exhaust fan 41.

[0062] A heat exchanger 14 and a heat exchange fan 15 are installed inside the first column shell 10. The heat exchange fan 15 forces indoor air into the first column shell 10 through the first air inlet 13, and then the indoor air flows out from the first air outlet 11 of the first column shell 10 after passing through the heat exchanger 14. A cross-flow fan 25 is installed inside the second column shell 20. The cross-flow fan 25 forces indoor air into the second column shell 20 through the second air inlet 23, and then the indoor air is blown out from the second air outlet 21 of the second column shell 20. A lower shell is located below the second column shell 20 and the third column shell 30. The lower shell serves as the foundation supporting the first column shell 10, the second column shell 20, and the third column shell 30, and also provides space for installing an exhaust fan 41. The exhaust fan 41 is located inside the lower shell 40 and is used to introduce the third airflow into the third column shell 30.

[0063] In some embodiments of the present invention, a fourth air inlet 43 is provided on the rear side wall of the lower shell 40, and the fourth air inlet 43 is connected to the air inlet of the exhaust fan 41; the fourth air inlet 43 is an outdoor fresh air inlet; a fresh air duct is connected to the fourth air inlet 43 to introduce fresh air from the outside. The exhaust fan 41 causes the fresh air to enter the third column shell 30 from bottom to top and is blown out from the third air outlet 31. In order to meet the user's various needs for fresh air introduced into the room, a functional module 42 is provided between the fourth air inlet 43 and the air inlet of the exhaust fan 41; the functional module 42 is a purification module and / or a humidification module.

[0064] In some alternative embodiments of the present invention, the fourth air inlet 43 may also be an indoor air inlet, and a functional module 42 is provided between the fourth air inlet 43 and the air inlet of the induced draft fan 41. This arrangement can be used to adjust indoor air quality without the induced draft fan 41 introducing external fresh air and reducing heat exchange between indoor and fresh air.

[0065] In some embodiments of the present invention, a vertically shaped air duct communicating with a third air outlet 31 is provided inside the third column housing 30. Multiple guide vanes 35 arranged vertically are provided inside the air duct, each guide vane 35 extending from front to back, with its rear end bent downwards to form a guide bend 351. The distance between the front and rear ends of the guide vane 35 located higher up is greater.

[0066] The airflow flows from bottom to top. Upon encountering each guide vane 35, it is guided by its guide bend 351, gradually changing from upward flow to forward flow. Therefore, the guide bend 351 changes the direction of the airflow, making the airflow change more gentle and reducing wind force loss. The guide bend 351 and the rest of the guide vane 35 are transitioned with rounded corners.

[0067] Furthermore, considering that the 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, this embodiment of the invention specifically provides multiple vertically arranged guide vanes 35 inside the third column housing 30, and the distance between the front and rear ends of the guide vanes 35 that are located higher up is larger, making the airflow from the third air outlet 31 more uniform in all vertical directions. 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 taken advantage of, as the air mixing effect on the upper side is poor, so that air can be delivered to places that require cooling, that is, to places that do not require soft air.

[0068] In some embodiments of the present invention, the distance between the two side walls of the second columnar shell 20 gradually decreases from back to front, forming a tapered shape; the distance between the two side walls of the third columnar shell 30 gradually decreases from back to front, forming a tapered shape.

[0069] In some embodiments of the present invention, the two sidewalls of the first column shell 10 are symmetrically arranged about a vertically extending reference plane; 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 intake interval 16 and the second air intake interval 26 are symmetrically arranged.

[0070] The symmetrical arrangement allows for a more uniform and consistent mixing of the airflow from the second air outlet 21, the third air outlet 31, and the first air outlet 11, as well as the indoor air flowing forward within the first air intake interval 16 and the second air intake interval 26, resulting in a better airflow mixing effect. Furthermore, the symmetrical arrangement of the three column shells with respect to the vertical reference planes extending forward and backward aligns with Chinese aesthetic preferences.

[0071] 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-to-back direction, for example, directing the airflow towards the front, left front, right front, etc. Furthermore, the first column housing 10 is equipped with an air guide plate 12 for guiding the lateral airflow direction of the first air outlet 11.

[0072] like Figures 8 to 11 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 air guide plate 12 changes the airflow direction of the heat exchange airflow, it controls the air guide 27 to operate, ensuring that the second airflow always merges into the first airflow. For example... Figure 8 As shown, when the air guide plate 12 swings forward, it causes the air guide component 27 to guide the air forward. Figure 10 As shown, when the air guide plate 12 swings to the left, it causes the air guide component 27 to guide the air to the left. Figure 11 As shown, when the 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 air guide plate 12 to control their coordinated operation.

[0073] like Figure 9 As shown, one side wall 281 of the air duct 28 inside the second column housing has a first clearance groove 2812 and a first sliding groove 2811 communicating with the first clearance groove 2812, and the other side wall 282 of the air duct 28 has a second clearance groove 2821. The first plate 271 is slidably installed in the first sliding groove 2811. Figure 9 As shown, the air guide 27 may include a first plate 271 and a second plate 272 arranged laterally at intervals. Of course, the second plate 272 and the first plate 271 are connected by other structures. Figure 9 Not shown in the diagram. The end of the first plate 271 near the second plate 272 has a backward-curved bend 2711, which forms an air guide channel 270 with a gradually decreasing distance from back to front between the bend 2711 and the second plate 272. The air guide 27 is rotatably mounted on the second column housing 20 about a vertical axis so that the lateral air outlet 21 can be changed by adjusting the relative position of the air guide channel 270 and the second air outlet 21.

[0074] like Figure 8 As shown, when the air guide channel 270 is directly opposite the second air outlet 21, it guides the non-heat exchange airflow to blow straight forward. Figure 10 As shown, the air guide 27 is positioned relative to... Figure 8 The position should be rotated clockwise so that the air guide channel 270 faces the left front, in order to guide the first airflow to blow out to the left front. Figure 11 As shown, the air guide 27 is positioned relative to... Figure 8 The state is to rotate counterclockwise so that the air guide channel 270 faces the right front, so as to guide the second airflow to blow out to the right front. Of course, the air guide 27 can be used to close the second air outlet 21. The structure of this air guide 27 in this embodiment is very simple and occupies very little space, making it particularly suitable for the narrow shape of the second air outlet 21, and the design is very ingenious.

[0075] In some alternative embodiments of the present invention, conventional rotating air guides can also be used to guide the airflow direction of the second air outlet 21 and the third air outlet 31.

[0076] In some embodiments of the present invention, in order 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.

[0077] The second and third column housings 20 and 30 rotate independently with a large rotation angle, allowing the vertical air conditioner indoor unit to meet the air supply needs of all indoor areas. For example... Figure 12 and Figure 13 As shown, taking the rotation of the second column housing 20 as an example, the second column housing 20 can rotate to the left or to the right, resulting in a larger air supply range.

[0078] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
