Description

Technical Field

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

[0002] With the development of the times and the advancement 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 are usually provided with one or more vertical strip-shaped air outlets on the front side of the housing, and an air guide device is used to achieve up and down, left and right swing air, thereby expanding the air supply angle.

[0004] On this basis, some existing technologies have made many improvements to the air outlet structure, but due to the constraints of the direction of the air outlet itself, 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 on people during cooling is difficult to solve, affecting the user experience. Summary of the Invention

[0005] The object of the present invention is to overcome the above problems or at least partially solve the above problems, and to provide a vertical air-conditioning indoor unit with better air supply experience and more diverse air supply modes.

[0006] Another object of the present invention is to increase the mixed air volume of a vertical air conditioner indoor unit.

[0007] In particular, the present invention provides an air conditioner indoor unit, comprising:

[0008] The first column housing is in the shape of a vertical column and has two first air outlets arranged in a transverse direction on its front side for blowing out heat exchange airflow;

[0009] The second column housing is in a vertical column shape and is arranged side by side with the first column housing in the transverse direction, forming an air outlet gap between the two. The front side of the second column housing is provided with a second air outlet for blowing out non-heat exchange airflow;

[0010] The vertical air conditioner indoor unit is configured to drive the indoor air in the air-inducing space to flow forward by means of negative pressure when air is discharged from at least one of the first air outlet and / or the second air outlet.

[0011] Optionally, the vertical air-conditioning indoor unit is configured to have an operating mode in which the heat exchange airflow blown out of the first air outlet and the non-heat exchange airflow blown out of the second air outlet are mixed in front of the vertical air-conditioning indoor unit; and

[0012] An air guide device is provided at each of the first air outlets for adjusting the angle between the flow directions of the heat exchange airflow and the non-heat exchange airflow.

[0013] Optionally, the wind guide device is an air guide tube, each of the air guide tubes is rotatably arranged at one of the first air outlets, and its peripheral wall includes at least two ventilation sections and one wind shielding section arranged along its circumference; and

[0014] Each of the air ducts is configured to be rotatable to a position where any one of the ventilation sections is opposite to the first air outlet, so as to allow the outlet air flow to enter the air duct through the ventilation section and then be blown out through the other ventilation sections, and to allow the direction of the ventilation section used for air outlet to be rotatably adjusted; or to be rotatable to a position where the wind shield section is opposite to the first air outlet, so as to block the first air outlet.

[0015] Optionally, each of the first air outlets is tilted in a direction laterally away from the first column housing so as to open obliquely forward; and

[0016] A movable first air guide plate is provided at each of the first air outlets to open or block the lateral air outlet path of the first air outlet; and

[0017] Each of the air guide tubes is configured to be rotatable to a position where the wind shielding section blocks other parts of the first air outlet when the first air guide plate blocks the lateral air outlet path of the first air outlet, so that the first air outlet is closed.

[0018] Optionally, each of the air guide tubes is prismatic in shape as a whole, and at least part of the side walls thereof constitute the ventilation section and the wind shielding section.

[0019] Optionally, the air guide tube is in the shape of a triangular prism as a whole, two of its three side walls constitute the two ventilation sections, and the other constitutes the wind shielding section.

[0020] Optionally, each of the ventilation sections is in the shape of a plate provided with a plurality of air dispersion holes.

[0021] Optionally, a second air inlet is provided on the peripheral wall of the second column housing and is open to the indoor environment for introducing indoor air; and

[0022] The vertical air-conditioning indoor unit further includes a second fan, which is disposed in the second column housing and is used to blow the non-heat exchange air flow out through the second air outlet.

[0023] Optionally, a second air guide plate is provided at the second air outlet, and the second air guide plate is rotatably mounted on the second column housing around a vertical axis.

[0024] Optionally, the two lateral sides of the first column housing are vertical surfaces extending forward and backward as a whole, and the back side is an outwardly convex curved surface with two sides tangent to the two side surfaces respectively; and

[0025] The two transverse side surfaces of the second column housing are vertical surfaces extending forward and backward as a whole, and the back surface is an outwardly convex curved surface with two sides respectively tangent to the two side surfaces.

[0026] Optionally, the vertical air-conditioning indoor unit further includes a lower column shell; and the bottoms of the first column shell and the second column shell are connected to the top of the lower column shell.

[0027] The vertical air-conditioning indoor unit of the present invention utilizes the first column shell to blow out the heat exchange airflow, utilizes the second column shell to blow out the non-heat exchange airflow, and forms an induced draft interval between the first column shell and the second column shell. In this way, when the first column shell and / or the second column shell discharges air, a negative pressure environment is formed at the induced draft interval, prompting the indoor air behind the vertical air-conditioning indoor unit to flow forward through the induced draft interval to mix with the outlet airflow of the first column shell or the second column shell, thereby forming an induced draft mixed air effect. The temperature of the mixed airflow is closer to the room temperature than the heat exchange airflow, and the comfort is higher, the wind feeling is softer, and the air volume and wind speed are increased, the air supply distance is longer, and the indoor cooling / heating speed is accelerated, thereby improving the energy efficiency of the air conditioner and achieving the effect of energy saving and emission reduction.

[0028] Furthermore, the non-heat exchange airflow from the second column can also be mixed with the heat exchange airflow. When the second column blows out indoor air, it can achieve a stronger air mixing effect, bringing the airflow closer to room temperature. When the second column blows out conditioned airflow such as fresh air, purified airflow, humidified airflow, or water washing airflow, these conditioned airflows can be mixed with the heat exchange airflow earlier and more frequently, enhancing the mixing rate and allowing it to be better diffused throughout the room.

[0029] Furthermore, the vertical air-conditioning indoor unit of the present invention is designed with two first air outlets, and a rotatable air guide is provided at each first air outlet, which can realize a variety of air supply modes. The air guide has at least two ventilation sections, and the air flow from the first air outlet of the first column shell is not blown directly to the indoor environment, but first enters the air guide through a certain ventilation section, and after briefly gathering in the inner cavity of the air guide, it is blown out through other ventilation sections of the air guide. In this way, different ventilation sections can be switched to be opposite to the first air outlet by rotating the air guide, and different ventilation sections can be used to supply air to the room, ultimately achieving the purpose of changing the air supply effect. For example, different ventilation sections can be made to have different parameters such as orientation and air outlet area when in the air supply position, so that the wind direction and air volume when supplying air are different. The structure is very novel and ingenious.

[0043] The present invention provides a vertical air conditioner indoor unit. This unit is the indoor portion of the air conditioner, used to condition the indoor air, such as for cooling / heating, dehumidifying, and introducing fresh air. This unit can be a conventional floor-standing cabinet unit or a vertical wall-mounted unit.

[0044] Figure 1 is a schematic front view of a vertical air-conditioning indoor unit according to one embodiment of the present invention; Figure 2 yes Figure 1 NN cross-sectional enlarged view; Figure 3 yes Figure 2 The schematic diagram of the vertical air conditioner indoor unit shown is when it is switched to the converged air supply mode; Figure 4 yes Figure 2 The diagram shows a vertical air conditioner indoor unit switched to surround air supply. Figure 3 The solid arrows indicate the direction of the heat exchange airflow, and the hollow arrows indicate the direction of the indoor airflow.

[0045] like Figures 1 to 4 As shown, the vertical air-conditioning indoor unit according to the present invention may generally include a first column housing 10 and a second column housing 70 .

[0046] The first column housing 10 is in the shape of a vertical column, with two first air outlets 11 and 12 arranged side by side in a horizontal direction on its front side for blowing out the heat exchange airflow. "Horizontal" is indicated in the figure, and the left-right direction perpendicular to the front-to-back direction of the vertical air conditioner indoor unit is "horizontal." When the vertical air conditioner indoor unit is in cooling mode, the heat exchange airflow is cold air. When the vertical air conditioner 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 outlets 11 and 12, completing the cooling and heating of the indoor environment.

[0047] The second column housing 70 is in the shape of a vertical column and is arranged side by side with the first column housing 10 in a horizontal direction. Specifically, the second column housing 70 is arranged on the left or right side of the first column housing 10. An air outlet space 13 is formed between the first column housing 10 and the second column housing 70. A second air outlet 82 is provided on the front side of the second column housing 70 for blowing out a non-heat exchange airflow. Specifically, the non-heat exchange airflow can be one or more of indoor air, fresh air, purified airflow, humidified airflow, or water-washing airflow, and its function is to assist in regulating the indoor environment.

[0048] When the vertical air conditioner indoor unit of the embodiment of the present invention is in operation, either the first column housing 10 or the second column housing 20 is selectively or simultaneously turned on to supply air. When air is discharged from at least one of the first air outlet 12 and / or the second air outlet 22, negative pressure is applied to drive the indoor air in the air induction compartment 13 to flow forward.

[0049] The first air outlet 12 and the second air outlet 22 can be in the form of an integral vertical bar extending from top to bottom, or can be in the form of a discontinuous vertical bar consisting of a plurality of vertically arranged sub-air outlets, so as to fully utilize the height space of the first column shell 10 and the second column shell 20.

[0050] Existing vertical air conditioner indoor units have limited visual differentiation and offer a poor airflow experience, leading to numerous user complaints. This is especially true when the air conditioner is in cooling mode, where users often experience low airflow temperatures and high air speeds, with the cold air blowing directly onto their bodies, causing discomfort. This is often referred to as the air being too "hard" rather than gentle enough.

[0051] In the embodiment of the present invention, when the first column housing 10 and / or the second column housing 20 discharge air, a negative pressure environment is formed at the air induction gap 13, forcing the indoor air behind the vertical air conditioner indoor unit to flow forward through the air induction gap 13 to mix with the air flow discharged by the first column housing 10 or the second column housing 20, thereby creating a induced mixed air effect. The temperature of the mixed air flow is closer to room temperature than the heat exchange air flow, providing higher comfort and a softer wind feel. It also increases the air volume and speed, and can deliver air over a longer distance.

[0052] In some embodiments of the present invention, the vertical air-conditioning indoor unit is further configured to have an operating mode that allows the heat exchange airflow blown out of the first air outlet 12 and the non-heat exchange airflow blown out of the second air outlet 22 to mix in front of the vertical air-conditioning indoor unit. Specifically, the normal directions of the first air outlets 11, 12 and the second air outlet 22 can be made to clamp an angle greater than 0 so that multiple airflows can be mixed. Of course, the air is also guided by the air guide structure to allow multiple airflows to mix. In this way, when the second column shell 20 also blows out indoor air, the amount of indoor air mixed in is greater and the mixing speed is faster, which can achieve a stronger air mixing effect and make the airflow closer to room temperature. When the second column shell 20 blows out regulated airflows such as fresh air, purified air, humidified air or water washing air, these regulated airflows can be mixed with the heat exchange airflow earlier and more, thereby enhancing the mixing rate and allowing it to be better diffused to various parts of the room.

[0053] In addition, since there is no need to install a heat exchanger in the second column shell 20, the second column shell 20 can be designed to be thinner, making it significantly thinner than the first column shell 10. This asymmetric design not only meets the need for mixed air, but also makes the appearance of the vertical air-conditioning indoor unit more novel and unique, thereby improving the competitiveness of the product. For example, the ratio of the width of the second column shell 20 in the transverse direction to the width of the first column shell 10 in the transverse direction 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 on both sides in the transverse direction that are the farthest apart in the transverse direction. The ratio of the depth dimension of the second column shell 20 in the front-to-back direction to the depth dimension of the first column shell 10 in the front-to-back direction is less than 1 / 2. This dimension refers to the distance between the two points on the outer walls of the second column shell 20 or the first column shell 10 on both sides in the transverse direction that are the farthest apart in the transverse direction. In this way, the size difference between the two is large enough to form a differentiated appearance of the two columns. The front and rear positions of the second air outlet 22 and the first air outlet 12 can be made flush or substantially flush, for example, the front and rear distance between the two is no more than 5 cm, so that the non-heat exchange airflow and the heat exchange airflow are better mixed.

[0054] In some embodiments, each first air outlet 11, 12 is provided with an air guide device to change the angle between the flow directions of the heat exchange airflow and the non-heat exchange airflow. Figure 2 and Figure 3 As shown, the air guide device is an air guide tube 50. Each air guide tube 50 is rotatably arranged at the first air outlet 11 or the first air outlet 12. The peripheral wall of each air guide tube 50 includes at least two ventilation sections 52, 53 and a wind shielding section 51 arranged along its circumference. The air guide tube 50 is a hollow structure with a cavity inside. For example Figure 2 As shown, the air duct 50 can have only two ventilation sections 52 and 53. Of course, more ventilation sections can also be provided. The ventilation sections 52 and 53 refer to sections through which air can enter and exit the air duct 50, and the wind-blocking section 51 refers to a solid section through which air cannot pass.

[0055] Each air duct 50 is configured to be rotatable to a position where any ventilation section 52, 53 is opposite to the first air outlet 11, 12, so as to allow the outlet air flow to enter the air duct 50 through the ventilation section 52, 53, and then be blown out through other ventilation sections, and then blown to the indoor environment, and the air duct 50 is allowed to rotatably adjust the orientation of the ventilation sections 52, 53 used for air outlet to change the outlet direction. It should be noted that "any ventilation section" is not a specific ventilation section. In this embodiment, all or at least part (at least two) of the ventilation sections 52, 53 can be used to be opposite to the first air outlet 11, 12, and which ventilation section 52, 53 is specifically enabled to be opposite to the first air outlet 11, 12 is optional. Alternatively, the air duct 50 can also be rotated to a position where the windshield section 51 is opposite to the first air outlet 11, 12 to block the first air outlet 11, 12, such as Figure 2 .

[0056] In this way, the airflow from the first air outlets 11 and 12 is not blown directly into the indoor environment. Instead, it first enters the air duct 50 through a certain ventilation section 52 or 53, briefly gathers within the interior of the air duct 50, and then is blown outward through other ventilation sections 52 or 53 of the air duct 50. In this way, by rotating the air duct 50, different ventilation sections 52 or 53 can be switched to face the first air outlets 11 or 12, and different ventilation sections 52 or 53 can be used to deliver air into the room, ultimately achieving the purpose of changing the air supply effect. For example, different ventilation sections 52 or 53 can have different parameters such as orientation and air outlet area when in the air supply position, so that the wind direction and air volume when delivering air are different. This structure is very novel and ingenious.

[0057] In some embodiments, as Figure 2 and Figure 3 As shown, each ventilation section 52, 53 is a plate-shaped plate provided with a plurality of air dispersion holes 502. Figure 3 When the vertical air conditioner is in operation, the heat exchange airflow first enters the air duct 50 through one ventilation section 52 and then exits through another ventilation section 53. During this process, the outgoing airflow passes through the ventilation sections twice, undergoes two breaks, and swirls around inside the air duct 50, further enhancing its softness, reducing airflow noise and creating a softer feel. This creates a quiet and comfortable air supply environment for the vertical air conditioner, enhancing human comfort.

[0058] Specifically, each air dispersion hole 502 can be an elongated hole with its length parallel to the length of the air duct 50, and the air dispersion holes 502 can be spaced apart along the circumference of the air duct 50. Compared to circular or square holes arranged in a matrix, these elongated holes provide a larger ventilation area, thus avoiding the problem of poor air flow due to a small ventilation area, which could affect the cooling / heating efficiency of the vertical air conditioner indoor unit. The ends of each air dispersion hole 502 can extend to positions adjacent to the ends of the air duct 50, so that its length covers the entire length of the air outlet.

[0059] In some embodiments, the width of any air diffusion hole 502 can be m, and the width of the solid portion separating it from any adjacent air diffusion hole 502 can be n, satisfying the following: 2 ≤ m / n ≤ 4. Preferably, 2.5 ≤ m / n ≤ 3.5, for example, m / n = 3. This achieves a balance between smooth and gentle airflow. The width m of each air diffusion hole 502 can be the same or different. The width n of each solid portion can be the same or different. Preferably, the width m of each air diffusion hole 502 is the same, and the width n of each solid portion is the same.

[0060] In some embodiments, as Figure 2 As shown, each first air outlet 11, 12 can be tilted in a direction laterally away from the first column housing 10 so as to open obliquely forward. That is, the first air outlet 11 on the left is opened toward the left front, and the first air outlet 12 on the right is opened toward the right front. In addition, a movable first air guide plate 60 is provided at each first air outlet 11, 12 for opening or blocking the lateral air outlet path of the first air outlet 11, 12. For example, for the first air outlet 11 on the left, blocking the air outlet path of the first air outlet 11 means blocking the first air guide plate 60 on the left side of the first air outlet 11, preventing air from being discharged to the left. Opening the lateral air outlet path of the air outlet 11 means opening the first air guide plate 60 on the left side of the first air outlet 11, allowing air to be discharged normally to the left. Accordingly, the air conditioner can control whether the first air outlets 11, 12 discharge air horizontally by controlling the first air guide plate 60. The first air guide plate 60 can be driven to move forward and backward by a motor and a gear rack structure.

[0061] When the first air guide plate 60 blocks the lateral air outlet path of the first air outlets 11 and 12, the air guide tube 50 can be rotated to a position where the wind shielding section 51 blocks other parts of the first air outlets 11 and 12, so that the first air outlets 11 and 12 are closed. Figure 2 That is, the embodiment of the present invention can use the first air guide plate 60 and the air guide tube 50 to jointly close the first air outlets 11 and 12.

[0062] like Figure 2 and Figure 4As shown, each first air guide plate 60 can be installed on the first column housing 10 so as to be movable forward and backward, so as to be retracted into the interior of the first column housing 10 to open the lateral air outlet path of the first air outlet 11, 12, as shown in FIG. Figure 4 Or extend the first column housing 10 forward to block the lateral air outlet path of the first air outlet 11, 12, such as Figure 2 .

[0063] In some embodiments, each air guide 50 may be prism-shaped as a whole, with at least some of its multiple side walls constituting ventilation sections 52, 53 and wind shielding section 51. A prism has multiple side walls and two axial end walls. For example, a triangular prism has three side walls, and a quadrangular prism has four side walls. At least some of its multiple side walls constitute ventilation sections 52, 53. Figures 1 to 4 As shown, the air duct 50 can be shaped as a triangular prism, with two of its three side walls (i.e., the three sides of the triangular prism) forming two ventilation sections 52 and 53, and the other forming a windshield section 51. In alternative embodiments, the air duct 50 can also be a quadrangular prism, a pentagonal prism, or other multi-prism to design more ventilation sections. Alternatively, the air duct 50 can be shaped as a cylinder, an elliptical cylinder, or other irregular shapes.

[0064] In some embodiments, the air guide tube 50 is made into a regular triangular prism shape as a whole, that is, the angle between any two adjacent side walls is 60°, and its rotation axes x1 and x2 are parallel to the central axis of the triangular prism, so that when the air guide tube 50 rotates around a fixed axis, each of its side walls can rotate to a position that closes the first air outlets 11 and 12.

[0065] It will be appreciated that the embodiments of the present invention do not require the air duct 50 to be a strictly geometrically defined triangular prism. In actual design and fabrication, its edges may be rounded, and its sides may be non-planar, such as curved surfaces. Of course, the air duct 50 may also be in the shape of a quadrangular prism or a pentagonal prism. Furthermore, the air duct 50 may also be in the shape of a cylinder or an elliptical cylinder. Such modifications are readily understood and implementable by those skilled in the art and will not be elaborated upon here.

[0066] Figure 5 yes Figure 2 The diagram shows a vertical air conditioner indoor unit switched to surround breeze mode; Figure 6 yes Figure 2 The diagram shows a vertical air conditioner indoor unit switched to front air supply mode; Figure 7 yes Figure 2 The diagram shows a vertical air conditioner indoor unit switched to left air supply mode; Figure 8 yes Figure 2 The diagram shows a vertical air conditioner indoor unit switched to right air supply mode.

[0067] The embodiment of the present invention achieves multiple air supply modes by providing two first air outlets 11 and 12 and two air guide tubes 50 .

[0068] When the indoor unit of the vertical air conditioner is turned off, Figure 2 As shown, the two first air guide plates 60 and the second air guide plates 90 are both in a closed state, and the wind shielding sections 51 of the two air guide tubes 50 respectively block the front of the first air outlets 11 and 12, so that the first air outlets 11 and 12 and the second air outlet 82 are all closed.

[0069] like Figure 3 As shown, the vertical air conditioner indoor unit is configured to allow the air outlet directions of the ventilation sections 53 of the two air guide tubes 50 to form an acute angle, so that the two heat exchange air flows blown out of the two first air outlets 11 and 12 converge in front of the first column housing 10, as shown in FIG. Figure 3 That is, the air outlet directions of the two first air outlets 11 and 12 are gradually brought closer to each other during the forward flow, so that the two air flows converge into one, making the wind force very strong and the air supply distance longer, meeting the air conditioner indoor unit's requirements for long-distance and strong air supply. The vertical air conditioner indoor unit can be equipped with a human body sensor. When the human body sensor detects that a person is far away from the vertical air conditioner indoor unit, the two air guide tubes 50 can be rotated to operate the convergent air supply mode. At this time, the second air guide plate 90 can guide the outlet air flow of the second air outlet 82 in a direction close to the first column housing 10 so as to merge into the heat exchange air flow.

[0070] like Figure 4 As shown, the two first air guide plates 60 can be opened, and the two air guide tubes 50 can be rotated so that the ventilation sections 52 for air discharge are oriented horizontally, so that the left first air outlet 11 discharges air to the left, and the right first air outlet 12 discharges air to the right, thereby forming an encircling air supply pattern. At this time, the second air guide plates 90 can be used to guide the airflow from the second air outlet 82 away from the first column housing 10 so that it can merge with the heat exchange airflow.

[0071] like Figure 5 As shown, compared Figure 4 , so that the two wind-shielding sections 51 face straight ahead, and the ventilation section 52 for air outlet faces obliquely rearward, so that after the heat exchange airflow is blown out, the wind sensation on the human body is weaker, forming an embracing breeze mode.

[0072] like Figure 6 As shown, the two ventilation sections 53 for discharging air are directed forward so as to discharge air forward, thereby forming a front air supply mode. Figure 7 As shown, the two ventilation sections 53 for discharging air are directed toward the left front so as to discharge air toward the left front, forming a left air supply mode. Figure 8As shown, the two ventilation sections 53 for discharging air are directed toward the right front so as to discharge air toward the right front, thereby forming a right air supply mode.

[0073] It should be noted that the above only illustrates some optional air supply modes of the present invention, and some air supply modes are not explicitly listed and introduced.

[0074] In some embodiments, sensors may be used to detect the position and state of the human body, and the controller may adjust the air supply mode accordingly.

[0075] For example, if a person is detected approaching a floor-standing air conditioner indoor unit, the front air supply mode can be activated. If a person is detected directly in front of the floor-standing air conditioner indoor unit, the surround air supply mode can be activated. Air flows from both sides, with only heat exchange air on the left side and a mixture of heat exchange air and indoor drainage air on the right side. This helps to enhance air flow efficiency in the space and improve occupant comfort.

[0076] When a person is detected in front of the left or right side of the vertical air conditioner indoor unit, the system enters left air supply mode or right air supply mode, with air flowing in the left or right front direction. When a person is detected as sleeping or quiet, the system enters surround breeze mode, with low wind speed, low noise, and a soft breeze, with air flowing gently from both sides, creating a quiet and comfortable environment for the user.

[0077] In some embodiments, as Figure 1 and Figure 2 As shown, the vertical air-conditioning indoor unit further includes a lower column housing 100. The lower column housing 100 constitutes the lower structure of the vertical air-conditioning indoor unit, and some other components of the air-conditioning, such as purification components, etc., may be arranged therein. When the vertical air-conditioning indoor unit is a floor-standing type, the bottom of the lower column housing 100 is placed on the ground. The bottoms of the first column housing 10 and the second column housing 70 are connected to the top of the lower column housing 100. The first column housing 10 and / or the second column housing 70 can be integrally formed with the lower column housing 100. In some embodiments.

[0078] In some embodiments, as Figure 2 and Figure 3 As shown, the peripheral wall of the second column housing 70 can be provided with a second air inlet 81 open to the indoor environment for introducing indoor air. The vertical air conditioner indoor unit also includes a second fan 42, which is disposed within the second column housing 70 and is configured to blow the non-heat exchange airflow through the second air outlet 22. The second fan 42 can be a crossflow fan, forming a second air duct 80 within the second column housing 70. The second air duct 80 is a crossflow duct, with the inlet and outlet of the second air duct 80 connected to the second air inlet 81 and the second air outlet 82, respectively. The provision of a dedicated crossflow duct can reduce airflow resistance.

[0079] In addition, if Figure 2 and Figure 3As shown, a second air guide plate 90 may be provided at the second air outlet 82 , and the second air guide plate 90 may be rotatably mounted on the second column housing 70 around a vertical axis to open and close the second air outlet 82 and to guide the air outlet direction of the second air outlet 82 .

[0080] In some alternative embodiments, the air inlet of the second column housing 70 may be connected to the lower column housing 100 so as to introduce one or more conditioned airflows, such as indoor air, purified airflow, humidified airflow, and fresh airflow, from the lower column housing 100. Alternatively, the second column housing 70 itself may be provided with a fresh air module, a purification module, or a humidification module so as to produce purified airflow, humidified airflow, and fresh airflow.

[0081] In some embodiments, as Figure 2 and Figure 3 As shown, the vertical air-conditioning indoor unit further includes at least one first fan 41. The number of the first fan 41 can be one or more. Figure 2 As shown, the number of first fans 41 can be one. First fan 41 is disposed within first column housing 10 to deliver the heat exchange airflow to first air outlets 11 and 12. Furthermore, the ratio of the rated air volume of second fan 42 to the rated air volume of first fan 41 can be between 0.35 and 0.45, inclusive, preferably between 0.39 and 0.41, for example, 0.4. In this embodiment, second fan 42 is designed to be smaller to reduce its power and avoid excessive indoor air circulation that could cause discomfort to the human body due to excessive wind force.

[0082] In some embodiments, as Figure 4 As shown, the ratio of the width B2 of the second column housing 70 in the transverse direction to the width B1 of the first column housing 10 in the transverse direction is between 0.2 and 0.25, inclusive, and preferably between 0.22 and 0.24. This asymmetric design not only meets the need for air mixing, but also makes the appearance of the vertical air conditioner indoor unit more novel and unique, enhancing the product's competitiveness.

[0083] In some embodiments, as Figure 4 As shown, the two lateral sides 18 of the first column housing 10 can be configured as vertical surfaces extending forward and backward, while the back surface 19 is a convex curved surface with two sides tangent to the two side surfaces 18. Similarly, the two lateral sides 78 of the second column housing 70 can be configured as vertical surfaces extending forward and backward, while the back surface 79 is a convex curved surface with two sides tangent to the two side surfaces 78. This rounded shape allows indoor air to enter the air outlet compartment 13 more smoothly, enhancing the air mixing effect.

[0084] like Figure 2As shown, a first air duct 20 can be further provided in the first column housing 10, with the front side of the opening of the first air duct 20 open to connect the two first air outlets 11 and 12. There is also one first fan 41, which is provided at the inlet of the first air duct 20. The first fan 41 can be a cross-flow fan, and the first air duct 20 is correspondingly a cross-flow air duct. The first column housing 10 includes a partition 15 located between the first air outlet 11 and the first air outlet 12 to guide the outlet airflow of the first air duct 20 to the two first air outlets 11 and 12. The partition 15 can be a columnar structure with a rear convex curved surface and a flat front surface.

[0085] A heat exchanger 30 may be disposed within the first column housing 10. The first column housing 10 may be provided with an air inlet. The heat exchanger 30 and a throttling device are connected via pipelines to the compressor, condenser, and other refrigeration components within the air conditioner's outdoor unit, forming a vapor compression refrigeration cycle. Driven by the first fan, indoor air enters the first column housing 10 through the air inlet. After completing forced convection heat exchange with the heat exchanger 30, it forms a heat exchange airflow and enters the first air duct 20. The heat exchange air is then blown into the room through the first air outlets 11 and 12 of the first column housing 10.

[0086] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
