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] With the development of the times and the progress of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners.

[0003] Existing vertical air conditioner indoor units typically have one or more vertical air outlets on the front of the casing, which are used to oscillate up, down, left, and right through an air guide device to expand the air delivery angle.

[0004] Based on this, some existing technologies have made many improvements to the air outlet structure. However, due to the constraints of the air outlet's orientation, the air supply direction, air supply range, and air supply distance of the air conditioner are still greatly limited. In particular, the problem of cold air blowing into people during cooling is difficult to solve, affecting the user experience. Summary of the Invention

[0005] The purpose of this invention is to overcome or at least partially solve the above problems and provide a vertical air conditioner indoor unit with a better air delivery experience.

[0006] A further objective of this invention is to increase the air mixing volume of a vertical air conditioner indoor unit.

[0007] A further objective of this invention is to improve the mixing rate and diffusion of non-heat exchange gas flow.

[0008] A further objective of the present invention is to make the amount of indoor air mixed in adjustable.

[0009] Specifically, the present invention provides an indoor air conditioning unit, comprising:

[0010] The first column shell is vertically columnar and has a first air outlet for blowing out heat exchange airflow; and

[0011] The second column shell is in the shape of a vertical column and is arranged side by side with the first column shell. The second column shell has a second air outlet for blowing out non-heat exchange airflow.

[0012] Optionally, the first air outlet is located on the front side of the first column housing, and the second air outlet is located on the front side of the second column housing, so as to allow the non-heat exchange airflow to mix with the heat exchange airflow in front of the vertical air conditioner indoor unit.

[0013] Optionally, the second column shell and the first column shell are arranged laterally, and an air-guiding gap is formed between them, so that when the first air outlet and / or the second air outlet emits air, the indoor air in the air-guiding gap is driven forward by the negative pressure.

[0014] Optionally, the indoor unit of the floor-standing air conditioner also includes a lower column housing; and

[0015] The first and second cylindrical shells extend upward from the top of the lower cylindrical shell.

[0016] Optionally, the lower column shell is configured to introduce or extract the non-heat exchange gas flow, and the lower column shell is in communication with the second column shell to inject the non-heat exchange gas flow into the second column shell.

[0017] Optionally, the non-heat exchange airflow is indoor air or fresh air;

[0018] The lower column shell is equipped with a fresh air inlet and an indoor air inlet.

[0019] Optionally, the second column housing is configured to be rotatably mounted on the lower column housing about a vertical axis to adjust the orientation of the second air outlet.

[0020] Optionally, the vertical air conditioner indoor unit also includes a damper configured to controllably adjust the flow area of ​​the air intake interval.

[0021] Optionally, the non-heat exchange airflow includes indoor air;

[0022] The second column shell has a second air outlet on its front side of its peripheral wall, and second air inlets opening towards the indoor environment on other parts of its peripheral wall to introduce indoor air; and

[0023] A second fan is installed inside the second column housing to guide the indoor air inside to be blown out through the second air outlet, and then mixed with the heat exchange airflow blown out by the first air outlet.

[0024] Optionally, the second column shell and the first column shell are arranged laterally, and an air-guiding gap is formed between them, so that when the first air outlet and / or the second air outlet emits air, the indoor air in the air-guiding gap is driven forward by the negative pressure.

[0025] The vertical air conditioner indoor unit of this invention features a second column housing parallel to the first column housing, specifically designed to blow out non-heat exchange airflow. This structure breaks with convention and is novel and ingenious. The non-heat exchange airflow mixes with the heat exchange airflow at the front of the vertical air conditioner indoor unit. The non-heat exchange airflow can be one or more of indoor air, fresh air, purified airflow, humidifying airflow, or water washing airflow. When the non-heat exchange airflow is indoor air, it mixes with the heat exchange airflow to form a mixed airflow. 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 air delivery distance. When the second column housing blows out regulated airflows such as fresh air, purified air, humidifying airflow, or water washing airflow, these regulated airflows can mix with the heat exchange airflow earlier and more extensively, enhancing the mixing rate and allowing for better diffusion throughout the room.

[0026] Furthermore, in the vertical air conditioner indoor unit of the present invention, an air-guiding gap is formed between the first and second column housings. Thus, when air is discharged from the first and / or second column housings, a negative pressure environment is created at the air-guiding gap, causing indoor air behind the vertical air conditioner indoor unit to flow forward through the air-guiding gap and mix with the airflow from the first or second column housings. This results in a larger volume and faster mixing of indoor air, creating a stronger air mixing effect. Furthermore, this also accelerates the indoor cooling / heating speed, improves the energy efficiency of the air conditioner, and achieves energy saving and emission reduction effects.

[0027] Furthermore, by setting a damper, the present invention makes the flow area of ​​the induced draft interval adjustable, thereby facilitating the adjustment of the amount of indoor air mixed in, and thus adjusting the outlet air temperature. Of course, when the user chooses to adjust the flow area of ​​the induced draft interval to zero, that is, to close the induced draft interval, the induced draft function of the induced draft interval can be turned off.

[0028] Furthermore, in the vertical air conditioner indoor unit of the present invention, the second column housing is rotatably mounted on the lower column housing around a vertical axis, so that the orientation of the second air outlet is adjustable. This also allows adjustment of the angle between the non-heat exchange airflow and the heat exchange airflow, thereby changing their convergence point. Moreover, by making the second column housing entirely rotatable, there is no need to design an air guide structure at the second air outlet, resulting in a simpler appearance for the second column housing.

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.

[0050] 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.

[0051] Figure 1This is a schematic front view of the vertical air conditioner indoor unit according to the first embodiment of the present invention. Figure 2 yes Figure 1 Enlarged cross-sectional view of NN.

[0052] like Figure 1 and Figure 2 As shown, the vertical air conditioner indoor unit of the first embodiment of the present invention generally includes a first column housing 10 and a second column housing 20.

[0053] The first columnar shell 10 is a vertical columnar shell, that is, a hollow columnar shell. The first columnar shell 10 has a first air outlet 12 for blowing out heat exchange airflow. The "heat exchange airflow" refers to the airflow that exchanges heat with the air conditioner's heat exchanger 17 to regulate the indoor temperature. The heat exchanger 17, along with the compressor, the outdoor unit's heat exchanger, the throttling device, and other refrigeration components, are connected via pipes to form a vapor compression refrigeration cycle system. When the indoor unit of the vertical air conditioner is in cooling mode, the heat exchange airflow is cold air; when the indoor unit is in heating mode, the heat exchange airflow is hot air. The heat exchange airflow is blown into the indoor environment through the first air outlet 12, completing the cooling or heating of the indoor environment.

[0054] The second column shell 20 is a vertical column, that is, a hollow columnar shell. The second column shell 20 has a second air outlet 22 for blowing out non-heat exchange airflow. Specifically, the non-heat exchange airflow can be one or more of indoor air, fresh air, purified airflow, humidifying airflow, or water washing airflow, and its function is to assist in regulating the indoor environment.

[0055] In the air conditioning industry, some vertical air conditioner indoor units have a dual-column design, but both columns are used to blow out heat exchange airflow, resulting in a very simplistic design. However, the vertical air conditioner indoor unit of this invention features a second column 20 parallel to the first column 10, specifically designed to blow out non-heat exchange airflow. This structure breaks with convention and is remarkably novel and ingenious. Furthermore, since no heat exchanger is needed within the second column 20, it can be designed to be significantly thinner than the first column 10. This asymmetrical design perfectly meets the air mixing requirements while also making the vertical air conditioner indoor unit more novel and unique in appearance, enhancing the product's competitiveness in terms of design.

[0056] like Figure 1 and Figure 2 As shown, the first air outlet 12 is located on the front side of the first column housing 10, and the second air outlet 22 is located on the front side of the second column housing 20, so as to allow non-heat exchange airflow to mix with heat exchange airflow in front of the vertical air conditioner indoor unit.

[0057] The appearance of existing floor-standing air conditioner indoor units is not significantly different, and the air delivery experience is poor, leading to many user complaints. In particular, when the air conditioner is cooling, users often feel that the air temperature is low and the air velocity is high, with cold air blowing directly on the body, causing discomfort. This is what people often refer to as the airflow being too "harsh" and not gentle enough.

[0058] In this embodiment of the invention, the vertical air conditioner indoor unit uses a first column housing 10 to blow out heat exchange airflow and a second column housing 20 to blow out non-heat exchange airflow. The non-heat exchange airflow mixes with the heat exchange airflow in front of the vertical air conditioner indoor unit. When the non-heat exchange airflow is indoor air, it mixes with the heat exchange airflow to form a mixed airflow. 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 air delivery distance. When the second column housing 20 blows out regulated airflows such as fresh airflow, purified airflow, humidified airflow, or water washing airflow, these regulated airflows can mix with the heat exchange airflow earlier and more extensively, enhancing the mixing rate and allowing it to diffuse better throughout the room.

[0059] Furthermore, such as Figure 2 As shown, the second column housing 20 and the first column housing 10 can be arranged laterally, and an air-guiding interval 13 is formed between them. The air-guiding interval 13 is connected to the indoor environment at both the front and back. "Lateral" is marked in the figure, and the left and right direction perpendicular to the front and back direction of the vertical air conditioner indoor unit is "latency".

[0060] When the indoor unit of the vertical air conditioner in this embodiment of the invention is running, the first column housing 10 and the second column housing 20 can be selectively or simultaneously activated to supply air. When air is discharged from the first air outlet 12 and / or the second air outlet 22, the indoor air within the air-guiding interval 13 is driven forward by the negative pressure, causing the indoor air behind the vertical air conditioner indoor unit to flow forward through the air-guiding interval 13, mixing with the airflow from the first column housing 10 or the second column housing 20, forming a induced air mixing effect. The temperature of the mixed airflow is closer to room temperature than the heat exchange airflow, resulting in higher comfort, a softer airflow, increased air volume and speed, and a longer air delivery distance. Especially when the second column housing 20 also blows out indoor air, this results in a larger amount of indoor air mixed in and a faster mixing speed, achieving a stronger air mixing effect and making the airflow even closer to room temperature.

[0061] like Figure 2As shown, 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 can be less than 1 / 2. This width refers to the distance between the two points on the outer walls of the second column shell 20 or the first column shell 10 that are furthest apart in the lateral direction. The ratio of the depth of the second column shell 20 in the front-to-back direction to the depth of the first column shell 10 in the front-to-back direction is also less than 1 / 2. This depth refers to the distance between the two points on the outer walls of the second column shell 20 or the first column shell 10 that are furthest apart in the front-to-back direction. This makes the size difference between the two sufficiently large, creating a differentiated appearance for the two columns. The front-to-back positions of the second air outlet 22 and the first air outlet 12 can be aligned or substantially aligned, for example, the front-to-back distance between them can not exceed 5 cm, so that the non-heat exchange airflow and the heat exchange airflow can be better mixed.

[0062] like Figure 2 As shown, a second air duct 25 is provided inside the second cylindrical shell 20, connecting to the second air outlet 22, to guide the non-heat exchange airflow inside the second cylindrical shell 20 more smoothly to the second air outlet 22. The distance between the two transverse sidewalls 251 and 252 of the second air duct 25 gradually decreases from back to front, forming a tapering shape. This tapering air duct can accelerate the airflow, allowing the non-heat exchange airflow to be blown out of the second air outlet 22 more quickly, which can, to some extent, compensate for the negative impact of not having a fan inside the second cylindrical shell 20 on the air velocity.

[0063] like Figure 2 As shown, the air intake interval 13 can be made into a gradually expanding shape with the lateral dimension gradually increasing from back to front, so that the airflow from the first air outlet 12 and the second air outlet 22 can better form a negative pressure in the outlet area of ​​the air intake interval 13, resulting in a larger airflow rate in the air intake interval 13.

[0064] Figure 3 yes Figure 2 Enlarged view of point A, Figure 4 yes Figure 2 The diagram shown illustrates the indoor unit of a vertical air conditioner when switched to left-facing airflow mode. Figure 5 yes Figure 2 The diagram shows the indoor unit of a vertical air conditioner switched to right-facing airflow mode.

[0065] like Figures 2 to 5 As shown, a second air guide component 26 is installed on the second column housing 20 to guide the lateral airflow direction of the second air outlet 22. "Guiding the lateral airflow direction" refers to changing the angle between the airflow direction and the front-to-back direction, such as directing the airflow towards the front, left front, right front, etc. In addition, a first air guide component 16 is installed on the first column housing 10 to guide the lateral airflow direction of the first air outlet 12.

[0066] The indoor unit of a floor-standing air conditioner can change the angle between the non-heat exchange airflow and the heat exchange airflow by adjusting the airflow direction of the first air outlet 12 and / or the second air outlet 22, thereby changing their convergence point. Specifically, the larger the angle between the airflow directions of the heat exchange airflow and the non-heat exchange airflow, the closer the convergence point is, i.e., closer to the floor-standing air conditioner indoor unit; the smaller the angle, the farther the convergence point is, i.e., farther away from the floor-standing air conditioner indoor unit. The floor-standing air conditioner indoor unit can adjust the aforementioned convergence point according to the human body position to avoid the convergence point being too close to the human body and causing discomfort.

[0067] Furthermore, the indoor unit of the vertical air conditioner can also be configured to: use the second air guide component 26 to adjust the lateral airflow direction of the second air outlet 22, so that the non-heat exchange airflow can merge into the heat exchange airflow of the first air outlet 12. That is, when the first air guide component 16 changes the airflow direction of the heat exchange airflow, it controls the second air guide component 26 to operate, ensuring that the non-heat exchange airflow can always merge into the heat exchange airflow. For example Figure 2 As shown, when the first air guide component 16 swings forward, it causes the second air guide component 26 to guide the air forward. Figure 4 As shown, when the first air guide component 16 swings to the left, it causes the second air guide component 26 to guide the air to the left. Figure 5 As shown, when the first air guide component 16 swings to the right, it causes the second air guide component 26 to guide air to the right. The main control board of the air conditioner can be electrically connected to the motors of both the second air guide component 26 and the first air guide component 16 to control their coordinated operation.

[0068] like Figure 3 As shown, the second air guide component 26 may include a first plate 261 and a second plate 262 arranged laterally at intervals. Of course, the second plate 262 and the first plate 261 are connected by other structures. Figure 3 Not shown in the diagram. The end of the first plate 261 near the second plate 262 has a backward-curved bend 2611, and the bend 2611 and the second plate 262 form an air guide channel 260 with a gradually decreasing distance from back to front. The second air guide component 26 is rotatably mounted on the second cylindrical shell 20 about the vertical axis x, so that the lateral air outlet direction of the second air outlet 22 can be changed by adjusting the relative position of the air guide channel 260 and the second air outlet 22.

[0069] For example Figure 2 and Figure 3 As shown, when the air guide channel 260 is directly opposite the second air outlet 22, it guides the non-heat exchange airflow to blow straight forward. Figure 4 As shown, the second air guide component 26 is positioned relative to... Figure 2 The position should be rotated clockwise so that the air guide channel 260 faces the left front, in order to guide the non-heat exchange airflow to blow out to the left front. Figure 5 As shown, the second air guide component 26 is positioned relative to... Figure 2The state is to rotate counterclockwise so that the air guide channel 260 faces the right front, so as to guide the non-heat exchange airflow to blow out to the right front. The structure of this air guide in this embodiment is very simple and occupies very little space, making it particularly suitable for narrow air outlets such as the second air outlet 22, and the design is very ingenious.

[0070] like Figure 3 As shown, a second air duct 25 communicating with the second air outlet 22 can be provided inside the second column housing 20. One transverse sidewall 251 of the second air duct 25 has a receiving groove 2512, and the other transverse sidewall 252 has a recess 2523. When the second air guide component 26 rotates to a transverse limit angle, the first plate 261 extends into the receiving groove 2512, so that the air guide surface of the bent portion 2611 is flush with the surface of the transverse sidewall 251 of the second air duct 25. Figure 4 This allows airflow to enter the air guide channel 260 more smoothly from the second air duct 25. Similarly, when the second air guide component 26 rotates to another lateral limit angle, the second plate 262 is embedded in the recess 2523 so that the air guide surface of the second plate 262 is flush with the surface of the lateral sidewall 252 of the second air duct 25, such as... Figure 5 .

[0071] Figure 6 yes Figure 2 The diagram shows the indoor unit of the vertical air conditioner when the second air outlet 22 is closed.

[0072] The second air outlet 22 can be closed using the second air guide component 26. For example... Figure 6 As shown, the second air guide component 26 is rotated to a position where the first plate 261 closes the second air outlet 22, thereby closing the second air outlet 22.

[0073] In some alternative embodiments, a conventional rotating air guide can also be used to guide the airflow direction of the second air outlet 22.

[0074] Figure 7 yes Figure 1 The diagram shown is a partial cut-out of the lower column casing 30 of a vertical air conditioner indoor unit. Figure 7 Only the structure below the dotted line is cut open.

[0075] like Figure 7As shown, the vertical air conditioner indoor unit also includes a lower column housing 30. The lower column housing 30 is used to introduce or draw in the aforementioned non-heat exchange airflow, and then discharge the non-heat exchange airflow to the second column housing 20. The first column housing 10 and the second column housing 20 extend upward from the top of the lower column housing 30. The first column housing 10 and the lower column housing 30 can be integrally formed, or the second column housing 20 and the lower column housing 30 can be integrally formed. The lower column housing 30 can constitute the lower casing of the vertical air conditioner indoor unit. When the vertical air conditioner indoor unit is floor-standing, the bottom of the lower column housing 30 is placed on the ground. In this embodiment of the invention, the lower column housing 30 is used to support and fix the first column housing 10 and the second column housing 20, making the overall structure of the vertical air conditioner indoor unit more stable.

[0076] In addition, such as Figure 1 As shown, the vertical air conditioner indoor unit may also include an upper connecting shell 40, with the top ends of both the first column shell 10 and the second column shell 20 connected to the upper connecting shell 40. The first column shell 10 and the upper connecting shell 40 can be integrally formed, or the second column shell 20 and the upper connecting shell 40 can be integrally formed. By providing the upper connecting shell 40, the structure of the vertical air conditioner indoor unit becomes more stable, and its appearance more harmonious.

[0077] A heat exchanger 17 and a first fan 14 are installed inside the first column housing 10 to generate heat exchange airflow. More specifically, air inlets 11 may be provided on the rear side or both lateral sides of the first column housing 10, and a first air duct 15 is provided inside the first column housing 10, connecting to a first air outlet 12. The first fan 14 is a cross-flow fan, which is located at the inlet of the first air duct 15. Under the action of the first fan 14, the indoor airflow enters the first column housing 10 through the air inlets 11, exchanges heat with the heat exchanger 17 to form a heat exchange airflow, and then enters the first air duct 15, which guides it to the first air outlet 12. Figure 2 .

[0078] like Figure 7 As shown, a lower fan 35 is installed inside the lower column shell 30 to transport non-heat exchange airflow to the second column shell 20. In this way, it is not necessary to install a fan inside the second column shell 20, so that the second column shell 20 can be designed to be thinner, and the space of the lower column shell 30 can be made more fully utilized.

[0079] Figure 8 yes Figure 1 The left view of the vertical air conditioner indoor unit shown is shown when the lower column housing 30 and the second column housing 20 are partially cut open. Figure 8 There are three curved dashed lines in total. The area between the upper and middle curves is the sectioning area, and the area below the lowest dashed line is the sectioning area.

[0080] like Figure 7 and Figure 8As shown, the downdraft fan 35 may include a impeller 351 and a volute 352. The impeller 351 is disposed inside the volute 352, which guides the airflow. The exhaust side of the volute 352 is connected to the second column housing 20 to discharge non-heat exchange airflow to the second column housing 20. Furthermore, the lower column housing 30 has a fresh air inlet 32 ​​and at least one indoor air inlet 31, both connected to the intake side of the volute 352. A fresh air duct 36 is connected to the fresh air inlet 32 ​​to introduce fresh airflow from the outside. The fresh air inlet 32 ​​is located on the rear wall of the lower column housing 30, and there are two indoor air inlets 31, located on the two transverse side walls of the lower column housing 30, respectively. This embodiment allows the downdraft fan 35 to draw in both fresh airflow and indoor air, achieving a dual effect. In addition, dampers can be installed at the fresh air inlet 32 ​​or the indoor air inlet 31 to control their opening and closing or their degree of opening, thereby adjusting the intake ratio of fresh airflow and indoor air.

[0081] like Figure 7 and Figure 8 As shown, the down fan 35 may also include a filter 353 disposed within the volute 352 for filtering the fresh air flow and indoor air.

[0082] If the aforementioned non-heat exchange airflow is a purification airflow, humidification airflow, or water washing airflow, a purification module, humidification module, or water washing module can be installed inside the lower column shell 30.

[0083] In some embodiments, such as Figure 8 As shown, the second air outlet 22 is vertically shaped. A vertically shaped second air duct 25, connecting to the second air outlet 22, is provided inside the second column housing 20. Multiple guide vanes 23 are arranged vertically within the second air duct 25. Each guide vane 23 extends from front to back, with its rear end bent downwards to form a guide bend 231. Non-heat exchange airflow flows from bottom to top. Upon encountering each guide vane 23, it is guided by its guide bend 231, gradually changing from upward flow to forward flow. Therefore, the guide bend 231 changes the airflow direction, making the airflow direction smoother and reducing wind speed loss. The guide bend 231 transitions to the rest of the guide vane 23 with a rounded corner.

[0084] Furthermore, considering that the non-heat exchange airflow enters the second column housing 20 from the bottom, it may cause the airflow volume in the middle or upper part of the second air outlet 22 to be relatively small. Therefore, in this embodiment of the invention, a plurality of vertically arranged guide vanes 23 are provided inside the second column housing 20, and the distance between the front and rear ends of the guide vanes 23 that are located higher is larger, so that the airflow from the second air outlet 22 is more uniform in all vertical positions.

[0085] Figure 9 This is a schematic front view of a vertical air conditioner indoor unit according to a second embodiment of the present invention; Figure 10 yes Figure 9A schematic left view; Figure 11 yes Figure 9 MM cross-sectional enlarged view; Figure 12 yes Figure 9 The diagram shown is a schematic of a vertical air conditioner indoor unit when both the first and second air guide components are directed forward.

[0086] like Figures 9 to 12 As shown, the main difference between the second embodiment and the first embodiment of the present invention is that the non-heat exchange airflow includes indoor air. A second air outlet 22 is provided on the front side of the peripheral wall of the second column shell 20. Second air inlets 21, which open towards the indoor environment, are provided on other parts of the peripheral wall of the second column shell 20 to introduce indoor air. A second fan 24 is provided inside the second column shell 20. The second fan 24 is used to cause the indoor air inside the second column shell 20 to be blown out through the second air outlet 22, and then mixed with the heat exchange airflow blown out by the first air outlet 12 to form a mixed air effect.

[0087] The second column housing 20 and the first column housing 10 are arranged laterally at intervals to form an air-guiding interval 13. The air-guiding interval 13 is open to the indoor environment at both ends. This allows the indoor air within the air-guiding interval 13 to flow forward due to negative pressure when air is discharged from the first air outlet 12 and / or the second air outlet 22.

[0088] When the indoor unit of the vertical air conditioner in this embodiment of the invention is running, the first column housing 10 and the second column housing 20 can be selectively or simultaneously activated to supply air. When air is discharged from the first air outlet 12 and / or the second air outlet 22, the negative pressure forces the indoor air within the air-drawing interval 13 to flow forward, 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 softer breeze, increased air volume and velocity, and a longer air delivery distance. Figures 9 to 12 As shown, the second air inlet 22 can penetrate the lateral side wall and rear wall of the second column housing 20 away from the first column housing 10, so that the second air inlet 21 opens backward and laterally away from the second column housing 20, thereby increasing the air intake range and increasing the air intake volume.

[0089] like Figure 11 and Figure 12 As shown, the second fan 24 can be a cross-flow fan with its axis parallel to the length direction of the second cylindrical casing 20. This vertically arranged cross-flow fan is suitable for the vertically shaped second air outlet 22. For example, the second air outlet 22 can be a continuous vertical strip extending from top to bottom, or it can be composed of multiple vertically arranged sub-outlets forming a discontinuous vertical strip. To match the cross-flow fan and improve its operating efficiency and reduce air resistance, such as... Figure 11As shown, a second air duct 25 can be formed inside the second cylindrical shell 20. The second air duct 25 is a cross-flow air duct, and its outlet is connected to the second air outlet 22. The second fan 24 is installed inside the second air duct 25. Of course, the second fan can also be an axial fan or a centrifugal fan, or other types of fans, or a cross-flow fan with a horizontally arranged axis. These fans are widely used in the air conditioning field and will not be described in detail here.

[0090] like Figures 11 to 12 As shown, a first air guide component 16 is installed on the first column housing 10 to guide the lateral airflow of the first air outlet 12. Specifically, each of the first air guide components 16 may include a group of air guide vanes extending vertically along their axis. Driven by a motor, each vane rotates synchronously to change the airflow direction. An air guide vane 27 is installed on the second column housing 20 to guide the lateral airflow of the second air outlet 22. Furthermore, the first air guide component 16 can be used to close the first air outlet 12, and the air guide vane 27 can be used to close the second air outlet 22, such as... Figure 11 .

[0091] Figure 13 This is a schematic front view of a vertical air conditioner indoor unit according to a third embodiment of the present invention; Figure 14 yes Figure 13 Enlarged cross-sectional view of CC; Figure 15 yes Figure 14 The diagram shows the indoor unit of a vertical air conditioner after the air damper is closed and the air intake interval is reached. Figure 16 yes Figure 15 The diagram shows the indoor unit of a vertical air conditioner after the second column casing has been rotated laterally outward.

[0092] like Figures 13 to 16 As shown, the main improvement of the third embodiment of the present invention compared with the first embodiment is that the vertical air conditioner indoor unit further includes a damper 50, which is configured to controllably adjust the flow area of ​​the air intake interval 13, thereby increasing or decreasing the flow area. Alternatively, the flow area can be adjusted to zero, that is, the air intake interval 13 can be completely closed. Specifically, the damper 50 can be installed on the lower column housing 30.

[0093] Increasing the flow area of ​​the air intake interval 13 increases the amount of indoor air mixed in, thus having a greater impact on the temperature of the heat exchange airflow. This means that the temperature of the cold airflow rises more significantly, while the temperature of the hot airflow drops more, resulting in a more comfortable airflow. Users who prioritize comfort can adjust this setting. Conversely, decreasing the flow area of ​​the air intake interval 13 reduces the amount of indoor air mixed in, weakening its impact on the temperature of the heat exchange airflow. Users who want to be directly exposed to cold / hot air for a more direct and noticeable cooling / heating experience can adjust this setting. Of course, the air intake interval 13 can also be closed to completely stop its air intake function. In summary, this invention, by making the flow area of ​​the air intake interval 13 adjustable, provides the indoor unit of the vertical air conditioner with more adjustment modes.

[0094] The damper 50 can be configured to rotatably adjust the flow area of ​​the air intake interval 13 about a vertical axis x1. The design of the rotating structure is relatively simple and can be directly driven by a motor. Specifically, the damper 50 can be located at the inlet of the air intake interval 13 and is a vertically extending prism, with its outer peripheral wall surface forming a windproof surface 51. The rotation axis x1 of the damper 50 is away from the windproof surface 51 and located behind the second column housing 20. The damper 50 is configured to rotate to a closed position where the windproof surface 51 blocks the air intake interval 13, such as... Figure 15 Or rotate to the closed position located behind the second column housing 20. In the open position, as... Figure 14 This allows the damper 50 to be positioned away from the air intake path of the induced draft interval 13, resulting in smoother air intake. In the open position, the baffle surface 51 can be positioned away from the first column housing 10 (e.g., Figure 14 In the middle, the first column shell 10 is located to the right of the second column shell 20, so that the windproof surface 51 faces to the right.

[0095] Furthermore, such as Figure 15 and Figure 16 As shown, the second column housing 20 can be configured to be rotatably mounted on the lower column housing 30 around a vertical axis to adjust the orientation of the second air outlet 12, thereby adjusting the air outlet direction of the second air outlet 12. The vertical air conditioner indoor unit can change the angle between the non-heat exchange airflow and the heat exchange airflow by adjusting the air outlet direction of the second air outlet 12, thereby changing the convergence position of the two. Specifically, the larger the angle between the airflow direction of the heat exchange airflow and the airflow direction of the heat exchange airflow, the closer the convergence position is, that is, closer to the vertical air conditioner indoor unit; the smaller the angle, the farther the convergence position is, that is, farther away from the vertical air conditioner indoor unit. The vertical air conditioner indoor unit can adjust the aforementioned convergence position according to the position of the human body to avoid the convergence position being close to the human body and causing discomfort. In addition, when it is necessary to mix the airflow from the two column housings, the second column housing 20 can also be configured to move with the movement of the first air guide component 16 to ensure that indoor air can be mixed with the heat exchange airflow and to prevent the two airflows from flowing away from each other.

[0096] This embodiment makes the second column shell 20 rotatable as a whole, eliminating the need for an additional air guiding structure at the second air outlet 22, thus making the appearance of the second column shell 20 more concise.

[0097] 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.
