Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a ceiling air conditioner panel, an air supply structure and an air conditioner. Background Art

[0002] Currently, ceiling air conditioners have the advantage of saving space and are becoming more and more popular among household users.

[0003] The existing ceiling air conditioner panel 4 is composed of an air return opening 2, an air outlet 5, and a sweeping blade 6, as Figures 1 to 2 shown. Air flows in from the air return opening, passes through the indoor fan and the air duct, and then flows out from the air outlet after being guided by the sweeping blade.

[0004] However, the existing panel air supply scheme has the following disadvantages:

[0005] Disadvantage 1: The air supply is concentrated, the temperature difference between the air supply temperature and the ambient temperature is large, which makes people feel uncomfortable, and the air supply is difficult to mix fully with the room air, resulting in an uneven room temperature field;

[0006] Disadvantage 2: Due to the effect of the sweeping blade, the air supply is at a certain angle with the air outlet direction, resulting in the air not reaching the ground directly and unable to achieve rapid cooling or heating.

[0007] Therefore, the air supply method and working mode of the existing ceiling air conditioner panel structure cannot meet the needs of users in different regions and different states, reducing the overall user comfort. Summary of the Invention

[0008] In view of this, the present invention aims to provide a ceiling air conditioner panel, an air supply structure and an air conditioner. By improving the ceiling air conditioner panel, a first air outlet and a second air outlet surrounding the panel are provided, and the air outlet direction of the second air outlet is set to be vertically downward, so that the heat exchange air flow blown out through the second air outlet can reach the ground directly, realizing rapid cooling and heating and meeting the air flow requirements in different situations.

[0009] To achieve the above object, the technical solution of the present invention is realized as follows:

[0010] A ceiling air conditioner panel, comprising:

[0011] An air return opening, arranged at a position close to the center on the panel;

[0012] A first air outlet, arranged outside the air return opening, and a sweeping blade is arranged at the first air outlet, so that the heat exchange air flow blows out along a direction forming an angle with the first air outlet under the action of the sweeping blade;

[0013] A second air outlet, arranged outside the first air outlet, so that the heat exchange air flow blows out vertically along the second air outlet.

[0014] For the ceiling machine panel described in the present invention, by improving the air outlet structure, the requirements for the air flow in different scenarios are met, and the air outlet can better mix with the room air, resulting in a softer air supply, more uniform temperature, and improved comfort for users.

[0015] Furthermore, a wind guide plate is provided inside the panel. Under the action of a driving device, the wind guide plate can change the air outlet state of the first air outlet and / or the second air outlet.

[0016] This setting further enhances the diverse requirements for the air flow of the panel in different scenarios, realizes the diverse setting of the air outlet direction, and further improves the comfort of users.

[0017] Furthermore, the second air outlet includes a plurality of air outlet holes, and the air outlet holes are arranged around the panel.

[0018] This setting improves the panel structure to connect the second air outlet with the air duct, meets the requirements for the air flow in different scenarios, enables the air outlet to better mix with the room air, and achieves the effects of a softer air supply and more uniform temperature.

[0019] Furthermore, the second air outlet includes at least two layers of air outlet holes. At least two layers of the air outlet holes are arranged along the direction in which the first air outlet is away from the return air outlet. The air outlet hole closest to the wind guide plate is the innermost air outlet hole, and the air outlet hole farthest from the wind guide plate is the outermost air outlet hole. The diameters of the air outlet holes are arranged in an increasing manner from the inside to the outside.

[0020] This design makes the air volume of each air outlet uniform, improves the uniformity of the air outlet of each air outlet, enables the air outlet to better mix with the room air, and ensures the comfort of users.

[0021] Furthermore, four first air outlets are provided on the panel, and a sweeping blade is arranged in each of the first air outlets.

[0022] This setting enables the air outlet to better mix with the room air, resulting in a softer air supply and more uniform temperature of the air outlet, and further improves the comfort of users.

[0023] The present invention also discloses a ceiling machine air supply structure, which includes the ceiling machine panel and the ceiling machine housing as described above. The panel is assembled and connected to the ceiling machine housing. An air supply channel is provided between the panel and the ceiling machine housing. One end of the air supply channel is communicated with the return air outlet, and the other end of the air supply channel is communicated with the first air outlet and the second air outlet. A wind guide plate is arranged in the air supply channel, and the wind guide plate is used to change the air outlet state of the first air outlet and / or the second air outlet.

[0024] This setting discloses an air supply structure for a ceiling-mounted air conditioner. By improving the panel structure, it can meet the air flow requirements in different situations.

[0025] Further, an exhaust cavity is provided at one end of the ceiling-mounted air conditioner housing close to the panel. The exhaust cavity is formed above the second air outlet. The air deflector is arranged on the panel between the first air outlet and the second air outlet. Under the action of the driving device, the air deflector can close the first air outlet or the inlet of the exhaust cavity.

[0026] This setting, through the improvement of the panel structure and the ceiling-mounted air conditioner housing structure, enables the air supply structure of the present invention to more accurately, quickly, and reliably meet the diverse air flow requirements in different scenarios.

[0027] Further, the range of the rotation angle of the air deflector is [0°, 90°].

[0028] This setting ensures the stability and reliability of the air supply at the first air outlet and the second air outlet, enables the air flow in different scenarios and working modes to be accurately controlled, and can control the air volume distribution between the first air outlet and the second air outlet, ensuring the comfort of users.

[0029] Further, a wind wheel is arranged in the air supply channel. The wind wheel is used to flow the air entering from the return air outlet out from the first air outlet and / or the second air outlet after heat exchange by the heat exchanger.

[0030] The present invention also discloses an air conditioner, including the ceiling-mounted air conditioner panel as described above, or the ceiling-mounted air conditioner air supply structure as described above.

[0031] Compared with the prior art, the ceiling-mounted air conditioner panel, air supply structure, and air conditioner of the present invention have the following advantages:

[0032] (1) For the ceiling-mounted air conditioner panel, air supply structure, and air conditioner of the present invention, by improving the panel, a second air outlet is added around the panel, which is composed of many air outlet holes. The diameter of the air outlet holes designed farther away from the air deflector is larger, and the direction is vertically downward, reaching the ground directly, so as to achieve rapid cooling and heating.

[0033] (2) For the ceiling-mounted air conditioner panel, air supply structure, and air conditioner of the present invention, through the air deflector in the air supply channel, the air deflector can be rotated 90° from the first position (perpendicular to the air outlet direction) to the second position (parallel to the air outlet direction) by motor control, which can control the air volume distribution between the first air outlet and the second air outlet, enabling the air supply to better mix with the room air, the air supply to be softer, the temperature to be more uniform, and improving the comfort of users.

[0034] (3) The ceiling air conditioner panel, air supply structure and air conditioner according to the present invention are improved by improving the panel, and a return air outlet, a deflector, a first air outlet, a second air outlet and a sweeping blade are provided on the panel.

[0044] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention will be described in detail below with reference to specific drawings.

[0045] Embodiment 1

[0046] As Figures 3 to 6 shown, the present invention discloses a ceiling air conditioner panel, including:

[0047] A return air outlet 2 is provided at a position close to the center on the panel 4.

[0048] The first air outlet 5 is arranged outside the air return outlet 2. Sweeping blades 6 are arranged at the first air outlet 5, so that the heat exchange air flow blows out along a direction forming an angle with the first air outlet 5 under the action of the sweeping blades 6.

[0049] The second air outlet 8 is arranged around the first air outlet 5, so that the heat exchange air flow blows out vertically along the second air outlet 8.

[0050] Specifically, through the improvement of the existing technology panel 4, in addition to setting the first air outlet 5 and the sweeping blades 6 on the panel 4 for the normal air outlet of the ceiling air conditioner, a second air outlet 8 is arranged on the outer periphery of the first air outlet 5, so that the heat exchange air flow can blow vertically towards the ground through the second air outlet, realizing the requirements of rapid cooling and heating, and meeting the requirements of the air outlet air flow in different scenarios.

[0051] The ceiling air conditioner panel described in the present invention realizes the requirements of the air outlet air flow in different scenarios through the improvement of the air outlet structure, and enables the air outlet to better mix with the room air, the air supply to be softer, the temperature to be more uniform, and the comfort of the user to be improved.

[0052] As a preferred example of the present invention, a wind guiding plate 7 is arranged inside the panel 4. The inside of the panel 4 refers to the side where the panel and the machine body are assembled to form an accommodating space. The wind guiding plate 7 can change the air outlet state of the first air outlet 5 and / or the second air outlet 8 under the action of a driving device.

[0053] Preferably, the driving device includes a motor. The wind guiding plate 7 rotates to a first position under the driving action of the motor. In this position, the wind guiding plate 7 can close the first air outlet. At this time, the heat exchange air flow can only blow out from the second air outlet 8. At this time, all the air outlets are vertically downward, which can quickly reach the ground directly, realizing the rapid cooling and heating function of the ceiling air conditioner, especially the rapid cooling and heating in the just-started state. When the room temperature reaches the set temperature, or according to the user setting, the wind guiding plate 7 can be gradually rotated to make both the first air outlet 5 and the second air outlet 8 have air outlets, so as to improve the diversity of the air outlet direction, make the air outlet better mix with the room air, the air supply to be softer, and the temperature to be more uniform. When the wind guiding plate moves to the second position, the second air outlet 8 stops blowing air, and all the heat exchange air flows to the first air outlet 5. The heat exchange air flow can be guided by the sweeping blades 6 to realize a wider angle and a farther distance of air supply.

[0054] This setting further improves the diverse requirements of the panel for the air outlet air flow in different scenarios, realizes the diversity of the air outlet direction, and further improves the comfort of the user.

[0055] As a preferred example of the present invention, the second air outlet 8 includes a plurality of air outlet holes 801 which are arranged around the panel 4, and the diameters of the air outlet holes 801 are arranged in an increasing manner from the inside to the outside.

[0056] As an example of the present invention, the inner side of the panel 4 is the side of the panel 4 close to the air return port 2, and the outer side of the panel 4 is the side opposite to the inner side of the panel and close to the outer edge of the panel 4.

[0057] Preferably, the air outlet holes 801 are arranged in an array on the panel 4.

[0058] As an example of the present invention, four first air outlets 5 are provided and are respectively arranged in the front, back, left and right directions of the air return port 2, and a sweeping blade 6 is arranged in each of the first air outlets 5.

[0059] The second air outlet 8 includes not less than two layers of air outlet holes 801, and at least two layers of the air outlet holes 801 are arranged along the direction in which the first air outlet 5 is away from the air return port 2. The air outlet holes 801 close to the air deflector 7 are the innermost layer of air outlet holes 801, and the air outlet holes 801 away from the air deflector 7 are the outermost layer of air outlet holes 801. The diameter of the innermost layer of air outlet holes 801 is the smallest, and the diameter of the outermost layer of air outlet holes 801 is the largest. For the air outlet holes 801 between the innermost layer of air outlet holes 801 and the outermost layer of air outlet holes 801, the diameters of the air outlet holes 801 are arranged in an increasing manner from the inside to the outside. Preferably, the second air outlet 8 includes three layers of air outlet holes 801.

[0060] As an example of the present invention, the air outlet holes 801 of each layer are distributed in a rectangular shape around the panel 4. Since the air resistance is greater when the ceiling air conditioner is in use and the distance from the air deflector 7 is farther, the aperture of the air outlet 801 farther from the air deflector 7 is designed to be larger to achieve uniform air volume at each air outlet. This design makes the air volume at each air outlet uniform, improves the uniformity of the air outlet at each air outlet, enables the air outlet to better mix with the room air, and ensures the comfort of the user.

[0061] Embodiment 2

[0062] The present invention discloses an air supply structure of a ceiling air conditioner, which includes: the panel 4 as described in Embodiment 1, and further includes a ceiling air conditioner housing 1. The panel 4 is arranged on the lower surface of the ceiling air conditioner housing 1. An air supply channel is arranged between the panel 4 and the ceiling air conditioner housing 1. One end of the air supply channel is communicated with the air return port 2, and the other end of the air supply channel is communicated with the first air outlet 5 and the second air outlet 8. An air deflector 7 is arranged in the air supply channel, and the air deflector 7 is used to change the air outlet state of the first air outlet 5 and / or the second air outlet 8.

[0063] This setting discloses an air supply structure of a ceiling-mounted air conditioner, which meets the air flow requirements in different situations through the improvement of the panel structure.

[0064] Preferably, a wind wheel 3 is arranged in the air supply channel, and the wind wheel 3 is used to discharge the air flow entering from the air return port 2 through the heat exchanger and the air outlet.

[0065] As a preferred example of the present invention, an exhaust cavity 9 is arranged at one end of the ceiling-mounted air conditioner housing 1 close to the panel 4. The exhaust cavity 9 is formed above the second air outlet 8. The air deflector 7 is arranged on the panel 4 between the first air outlet 5 and the second air outlet 8. The air deflector 7 can close the first air outlet 5 or the inlet of the exhaust cavity 9 under the action of the driving device.

[0066] Through the improvement of the panel structure and the structure of the ceiling-mounted air conditioner housing 1, this setting enables the air supply structure of the present invention to more accurately, quickly and reliably meet the diverse requirements of the air flow in different scenarios.

[0067] As a preferred example of the present invention, the value range of the rotation angle of the air deflector 7 is [0°, 90°].

[0068] This setting ensures the stability and reliability of the air supply of the first air outlet 5 and the second air outlet 8, enables the air flow in different scenarios and working modes to be accurately controlled, and can control the air volume distribution of the air supply at the first air outlet 5 and the second air outlet 8.

[0069] When the air deflector 7 is in the horizontal state, that is, as shown in Figure 4 the air deflector 7 is in the first position. The setting direction of the air deflector is perpendicular to the air outlet direction of the air outlet. At this time, the air deflector 7 closes the first air outlet 5, and all the heat exchange air flows out through the second air outlet 8. The air deflector can be controlled by a motor to rotate 90° from the first position (perpendicular to the air outlet direction) to the second position (parallel to the air outlet direction). At this time, the exhaust cavity 9 and the air supply channel are separated by the air deflector 7, that is, the second air outlet 8 is equivalent to being closed. At this time, all the heat exchange air flows to the first air outlet 5, and the heat exchange air flow can be guided by the sweeping blades 6 to achieve a wider angle and a farther distance of air supply. When the air deflector 7 is at a certain position between the first position and the second position, there will be heat exchange air flow out of the first air outlet 5 and the second air outlet 8. The air outlet directions of the air flowing through the first air outlet 5 and the second air outlet 8 are different, realizing the diversity design of the air outlet direction, making the air supply better mixed with the room air, the air supply softer and the temperature more uniform.

[0070] Embodiment 3

[0071] The present invention also discloses a control method for a ceiling air conditioner, including the ceiling air conditioner panel described in Embodiment 1 or the air supply structure described in Embodiment 2, and its control method includes the following steps:

[0072] S1: In the state when the air conditioner just starts running or the control mode is the rapid cooling and heating mode;

[0073] S2: The air deflector 7 rotates to the first position, the first air outlet 5 is blocked, and the heat exchange air flow exits from the second air outlet 8;

[0074] S3: When the room temperature reaches the set temperature, the air deflector can be gradually rotated. The air deflector 7 rotates to any preset position between the first position and the second position under the action of the driving device according to the control module instruction or preset conditions;

[0075] S4: When the control mode is controlled to the wide-angle blowing state, the air deflector 7 rotates to the second position under the action of the driving device, the second air outlet 8 is blocked, and the heat exchange air flow exits from the first air outlet 5.

[0076] The control method for the ceiling air conditioner disclosed by the present invention meets the air flow requirements for different situations. For example, when the air conditioner just starts running, the air deflector 7 is turned to the first position to close the first air outlet 5. At this time, all the air outlets are vertically downward, which can improve the direct reach to the ground and achieve rapid cooling and heating. When the room temperature reaches the set temperature, the air deflector 7 can be gradually rotated so that both the first air outlet 5 and the second air outlet 8 have air flow, meeting the diverse requirements for the air outlet direction, making the air flow better mixed with the room air, and achieving a softer air supply and more uniform temperature effect.
