Description

[0001] This application is a divisional application of the application filed on December 29, 2018, with application number 201811647306.0 and invention title "Air outlet panel and air conditioner". Technical Field

[0002] This invention relates to the field of air conditioning, and more specifically, to a control method, a control device, and an air conditioner. Background Technology

[0003] As people's living standards improve, their demands for air conditioning have evolved from simply providing cooling and heating functions to demanding comfort. For example, in the use of existing ducted air conditioners, the limitations of the installation location and the difference in density between warm and cold air can easily lead to uneven indoor temperature distribution, resulting in a poor user experience. Furthermore, once the indoor temperature stabilizes, some users, such as the elderly and children, are particularly sensitive to drafts, especially in the hot summer. Prolonged exposure to cold air can easily cause discomfort and harm to their health, even leading to illnesses like colds. Existing air conditioning systems often fail to provide users with a comfortable draft. Summary of the Invention

[0004] The purpose of this invention is to provide a control method, control device, and air conditioner that can effectively solve the problem of uneven temperature in the air field and improve user comfort.

[0005] This application provides a control method applied to an air conditioner. The air conditioner includes an air outlet panel, which includes a front air outlet and a lower air outlet. The front air outlet is used to send air forward and is provided with a front air outlet guide vane assembly. The lower air outlet opens downward and is provided with a lower air outlet guide vane assembly. The front air outlet guide vane assembly and the lower air outlet guide vane assembly operate independently of each other. The front air outlet guide vane assembly includes an outer guide vane assembly and an inner guide vane assembly that operate independently of each other. The control method includes controlling the outer air guide plate assembly, the inner air guide plate assembly, and the lower air outlet air guide plate assembly to achieve a multi-functional air supply mode through the cooperation of the front air outlet and the lower air outlet.

[0006] This application also provides a control device, including a processor and a memory storing a computer program, wherein the processor executes the computer program to implement the steps of the control method as described in the above embodiments.

[0007] This application also provides an air conditioner, including the control device described in the above embodiments.

[0008] Through the above technical solutions, in the control method, control device, and air conditioner of the present invention, since the air outlet panel is provided with two air outlets, a front air outlet and a lower air outlet, and the air guide plates on the two air outlets are independently controlled and operated, the problem of the air conditioner's difficulty in downward airflow, especially the difficulty in conducting hot air, which makes users feel cold in their legs and feet, can be solved, and a "carpet-like" heating effect can be achieved. In particular, since hot air has a relatively low air density, the air outlet panel of the present invention, by setting a lower air outlet air guide plate assembly that can control the lower air outlet, and by adjusting the combined action of the front air outlet air guide plate assembly and the lower air outlet air guide plate assembly, can effectively conduct hot air downwards to various areas towards the ground, achieving further control over the conduction angle of hot air, thereby effectively solving the problem of uneven indoor temperature field, giving users more choices, and providing a stronger sense of comfort from the airflow reaching the user.

Detailed Implementation

[0012] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used to describe the relative positional relationships of components in relation to the directions shown in the accompanying drawings or in relation to vertical, perpendicular, or gravitational directions. "Inner" and "outer" and "front" and "rear" are relative to the user's viewing angle; the side closer to the user is "outer" or "front," and the side farther from the user is "inner" or "rear."

[0014] To address the problems of limited airflow angle and difficulty in downward airflow caused by the air guide vanes on the air outlet panels of existing air conditioners, as well as uneven temperature distribution in indoor spaces, this invention provides a novel air outlet panel. (See attached image) Figures 1 to 4 As shown, the air outlet panel 800 includes: Front air outlet 1, used for forward air delivery and equipped with front air outlet guide vane assembly 10; and The lower air outlet 2 has an opening facing downwards and is equipped with a lower air outlet guide plate assembly 3; Among them, the front air outlet guide vane assembly 10 and the lower air outlet guide vane assembly 3 operate independently of each other.

[0015] As can be seen, in the air outlet panel 800 of the present invention, since the air outlet panel 800 is provided with two air outlets, a front air outlet 1 and a lower air outlet 2, and the air guide plates on the two air outlets are independently controlled and operated, the problem of the air conditioner's difficulty in downward airflow, especially the difficulty in conducting hot air, which makes users feel cold in their legs and feet, can be solved, and a "carpet-like" heating effect can be achieved. Since hot air has a relatively low air density, the air outlet panel 800 of the present invention, by setting a lower air outlet air guide plate assembly 3 that can control the lower air outlet 2, and by adjusting the combined action of the front air outlet air guide plate assembly 10 and the lower air outlet air guide plate assembly 3, can effectively conduct hot air downwards to various areas towards the ground, achieving further control over the conduction angle of hot air, thereby effectively solving the problem of uneven indoor temperature field, giving users more choices, and providing a stronger sense of comfort from the airflow reaching the user.

[0016] Furthermore, the air outlet panel 800 of the present invention, through the cooperation of the front air outlet 1 and the lower air outlet 2, can further realize a multi-functional air supply mode with various effects such as "wide-angle" air supply and zoned air supply, which is conducive to meeting the actual needs of more different users, which will be described in detail below.

[0017] See Figure 1 and Figure 4 As shown, preferably, the front air outlet 1 and the lower air outlet 2 can be L-shaped and perpendicular to each other. Of course, the front air outlet 1 and the lower air outlet 2 can also be non-perpendicular to each other and can be set at a certain angle, depending on the actual installation environment.

[0018] In the air outlet panel 800 of the present invention, see Figures 2 to 5 As shown, the front air outlet guide vane assembly 10 includes an outer guide vane assembly 4 and an inner guide vane assembly 5 that operate independently of each other. Under the dual air guiding effect of the inner guide vane assembly and the outer guide vane assembly 4, the air guiding direction and air guiding effect of the front air outlet 1 are more selective, and the airflow reaching the user is gentler.

[0019] To achieve the zoned air supply effect at front air outlet 1, see [link / reference]. Figures 5 to 7 As shown, the front air outlet 1 may include a horizontal left-side zone and a horizontal right-side zone. The inner air guide plate assembly 5 includes a left air guide plate assembly 51 arranged in the horizontal left-side zone and a right air guide plate assembly 52 arranged in the horizontal right-side zone. The left air guide plate assembly 51 and the right air guide plate assembly 52 each include multiple inner vertical air guide plates 501 arranged horizontally at intervals along the front air outlet 1 and pivoting along the vertical pivot axis of the front air outlet. The left air guide plate assembly 51 and the right air guide plate assembly 52 operate independently, achieving a zoned air supply effect for the horizontal left-side zone and the horizontal right-side zone.

[0020] Specifically, in one embodiment of the present invention, such as Figures 5 to 7 As shown, both the left air guide plate assembly 51 and the right air guide plate assembly 52 can be provided with an inner air guide plate drive mechanism 503 (including a drive motor) for driving the inner vertical air guide plates 501 of their respective areas. The multiple inner vertical air guide plates 501 on the left air guide plate assembly 51 and the right air guide plate assembly 52 can be connected through the inner air guide plate connecting rod assembly 504. The inner air guide plate drive mechanism 503 is connected to the inner air guide plate connecting rod assembly 504 through the inner air guide plate connecting rod mechanism 502 to drive the inner vertical air guide plates 501 of their respective areas to pivot independently. That is, the multiple inner vertical air guide plates 501 on the left air guide plate assembly 51 and the right air guide plate assembly 52 can rotate in the same or different directions to achieve horizontal zoned air supply on the front air outlet 1.

[0021] It should be noted that in the air outlet panel 800 of the present invention, the inner vertical air guide plate 501, as the upstream of the air outlet side of the air outlet panel 800, is usually set to an open state so that the airflow flows outward through the outer air guide plate assembly 4 or the lower air outlet air guide plate assembly 3. Further, see... Figure 7 As shown, the inner vertical air guide plate 501 has multiple perforated air-diffusing micro-holes 101 extending through the plate surface. The shape and size of the air-diffusing micro-holes 101 can vary; preferably, the cross-sectional area of ​​the air-diffusing micro-holes 101 ranges from 19 square millimeters to 42 square millimeters. Therefore, even when the inner vertical air guide plate 501 is completely parallel to the front air outlet cross-section, airflow can still exit from the air-diffusing micro-holes 101 on the inner vertical air guide plate 501. In comparison, when the inner vertical air guide plate 501 rotates to... Figure 6 At the position shown, the airflow through the inner vertical guide vane 501 is at its maximum, with relatively large air volume and velocity. When the inner vertical guide vane 501 rotates to the position shown... Figure 7 At the indicated position, the airflow passes through numerous densely distributed micro-perforations 101, resulting in a slower, gentler, and more uniform airflow, providing a comfortable, draft-free experience. Therefore, users can select the appropriate airflow volume and effect according to their actual needs.

[0022] Similarly, in the outer air guide plate assembly 4 of the front air outlet 1, the front air outlet 1 includes a vertically upward partition and a vertically downward partition. The outer air guide plate assembly 4 includes an upper air guide plate assembly 41 arranged in the vertically upward partition and a lower air guide plate assembly 42 arranged in the vertically downward partition. The upper air guide plate assembly 41 and the lower air guide plate assembly 42 each include multiple outer transverse air guide plates 401 arranged vertically at intervals along the front air outlet 1 and pivoting along the transverse pivot axis of the front air outlet. Therefore, the front air outlet 1 can further realize the function of vertical partitioned air supply through the outer air guide plate assembly 4. For example, specifically, the outer air guide plate assembly 4 may include two independently controlled, horizontally arranged outer transverse air guide plates 401. The upper outer transverse air guide plate 401 and the lower outer transverse air guide plate 401 are provided with pivoting power by their respective drive motors to independently pivot and guide air.

[0023] Furthermore, in the air outlet panel 800 of the present invention, the outer transverse air guide plate 401 of the outer air guide plate assembly 4 pivots around the transverse pivot axis of the front air outlet between the closed position and the extreme open position of the outer air guide plate. In the closed position, the outer transverse air guide plate 401 is parallel to the front air outlet cross-section of the front air outlet 1. In the extreme open position, the angle between the outer transverse air guide plate 401 and the front air outlet cross-section in the opening pivot direction from the closed position to the extreme open position is not less than 120°. Typically, in the air outlet panel 800 of the present invention, the movement range of the outer transverse air guide plate 401 is 0° to 120°, and the working range is 35° to 120°. See [reference needed]. Figure 8 and Figure 9 As shown. Furthermore, the pivot axis of the outer transverse air guide plate 401 can be set on the central axis in the width direction of the plate surface, allowing the outer transverse air guide plate 401 to pivot upwards or downwards in either the forward or reverse direction. Because the outer transverse air guide plate 401 has a wider and more adjustable angle, it can achieve a "wide-angle" air delivery effect, further making the temperature field of the indoor space more uniform. Since cold air has a higher density and tends to sink quickly, timely upward conduction of cold air is beneficial to the uniformity of cold air in the room, achieving a "waterfall-like" cooling effect and improving the user's comfort experience.

[0024] At the same time, multiple air-diffusing micro-holes 101 penetrating the surface of the outer horizontal air guide plate 401 can also be provided to further improve the "windless" effect of the air outlet.

[0025] In the air outlet panel 800 of the present invention, preferably, the lower air outlet guide plate assembly 3 is configured to selectively deliver air to the front or rear. Specifically, the pivot axis of the lower air outlet guide plate 301 can be located at the central axis, which coincides with or is parallel to the horizontal line connecting the midpoints of the wide sides of the lower air outlet guide plate 301 and is located vertically above this horizontal line. This enables multi-directional airflow guidance, making it particularly suitable for larger indoor spaces, thus providing greater selectivity in the airflow direction of the lower air outlet guide plate 301. Alternatively, the pivot axis of the lower air outlet guide plate 301 of the lower air outlet guide plate assembly 3 can also be located on the rear edge of the lower air outlet guide plate 301.

[0026] Specifically, the lower air outlet guide plate assembly 3 includes a lower air outlet guide plate 301 that pivots around a lateral pivot axis of the lower air outlet. The lower air outlet guide plate 301 pivots around the lateral pivot axis of the lower air outlet between a closed position and a maximum open position. In the closed position, the lower air outlet guide plate 301 is parallel to the lower air outlet cross-section of the lower air outlet 2. In the maximum open position, the angle between the lower air outlet guide plate 301 and the lower air outlet cross-section is no greater than 90° in the opening pivot direction from the closed position to the maximum open position, thus achieving the effect of front-to-back air guidance by the lower air outlet guide plate 301. (See also...) Figure 11 and Figure 12 As shown, the lower air outlet guide vane 301 can guide air towards the front side of the air outlet panel 800 or towards the rear side of the air outlet panel 800. The lower air outlet guide vane 301 has a movement range of 0° to 180° and an operating angle of 30° to 90°. In some specific embodiments of the air outlet panel 800 of the present invention, such as... Figures 8 to 14 As shown in the drawings, various air guiding methods are illustrated by combining the lower air outlet guide plate 301 and the outer horizontal guide plate 401.

[0027] Meanwhile, the lower air outlet 2 includes a horizontal front section and a horizontal rear section. The lower air outlet guide vane assembly 3 includes a front guide vane assembly arranged in the horizontal front section and a rear guide vane assembly arranged in the horizontal rear section. Both the front and rear guide vane assemblies include a lower air outlet guide vane 301 that pivots along the horizontal pivot axis of the lower air outlet. The lower air outlet guide vane 301 in the front and rear guide vane assemblies can be a single piece, or both the front and rear guide vane assemblies can include multiple lower air outlet guide vanes 301 arranged at horizontal intervals along the lower air outlet 2, to achieve the function of front and rear section air supply from the lower air outlet 2.

[0028] Furthermore, the lower air outlet guide plate assembly 3 may also include one lower air outlet guide plate 301 pivoting along the lateral pivot axis of the lower air outlet, or multiple lower air outlet guide plates 301 arranged at lateral intervals along the lower air outlet 2. The lateral pivot axis of the lower air outlet guide plate 301 is parallel to the rear long side of the lower air outlet guide plate 301. This lateral pivot axis of the lower air outlet is generally parallel to the rear long side located at the rear, or coincides with the rear long side.

[0029] Preferably, the lower air outlet guide plate 301 may be provided with multiple air dissipation micro-holes 101 that penetrate the plate surface.

[0030] In addition, the present invention also provides an air conditioner, see [link to relevant documentation]. Figure 1 As shown, the air conditioner includes the aforementioned air outlet panel 800, and therefore also includes all the advantages of the aforementioned air outlet panel 800, which will not be elaborated further.
