Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, air conditioners that can regulate temperature have been increasingly widely used.

[0003] The inventor has found through research that some existing air conditioners have low heating or cooling efficiency after being started. Utility Model Content

[0004] The utility model aims to provide an air conditioner which can improve the efficiency of heating or cooling.

[0005] The embodiment of the utility model is achieved as follows:

[0006] In a first aspect, the utility model provides an air conditioner, comprising:

[0007] A shell body, wherein the shell body is provided with an air outlet;

[0008] An upper diffuser section, which is arranged at the air outlet;

[0009] An upper air guide plate, which is arranged at the air outlet and is rotatably connected to the shell;

[0010] A lower air guide plate, which is arranged at the air outlet and is rotatably connected to the shell;

[0011] Among them, the lower air guide plate can be opened to a preset position. When the lower air guide plate is in the preset position, the distance between the upper end of the lower air guide plate and the upper diffuser section is 0 to 10 mm, which is used to guide the airflow blown out of the air outlet downward.

[0012] Through the above arrangement, most of the airflow can be guided downward. When heating or cooling, the cold air or the warm air can be delivered to the lower part of the room faster, accelerating the temperature change of the ground or the user's activity area, thereby improving the cooling or heating efficiency.

[0013] In an optional embodiment, when the lower air guide plate is in a preset position, the upper end of the lower air guide plate abuts against the upper diffuser section.

[0014] Through the above arrangement, more airflow can be guided downward by the lower air guide plate to further improve the efficiency of cooling or heating.

[0015] In an optional embodiment, when the lower air guide plate is in a preset position and the upper air guide plate is in a closed position, the upper air guide plate and the lower air guide plate are used to guide the airflow blown out from the air outlet to be discharged downward.

[0016] Through the above arrangement, when the upper air guide plate is in the closed position, the lower air guide plate can be rotated from the closed position to the preset position, and at this time, since the upper air guide plate is in the closed state, the airflow generated by the air conditioner will also be guided downward by the inner side of the upper air guide plate to increase the speed at which the cold or heated air can be delivered to the lower part of the room.

[0017] In an optional embodiment, the upper air guide plate has a preset open position range. When the upper air guide plate is in the preset open position range and the lower air guide plate is in the closed position, the upper air guide plate and the lower air guide plate are used to guide the airflow blown out of the air outlet upward.

[0018] Through the above settings, in cooling mode, the lower air guide plate can be controlled to close, and the upper air guide plate can be rotated within the preset opening position range to guide the airflow blown out of the air outlet upward. Since the cold air flows from top to bottom, it can form natural convection with the rising hot air in the room, which can reduce the room temperature relatively evenly.

[0019] In an optional embodiment, the end of the air outlet away from the upper air guide plate is the lower air outlet end, and the angle between the upper diffuser section along the extension direction close to the air outlet and the preset straight line passing through the lower air outlet end is α;

[0020] When the lower air guide plate is at the preset position, the angle between the direction from the upper end of the lower air guide plate to the lower end of the lower air guide plate and the preset straight line is β;

[0021] The preset straight line is parallel to the height direction of the air conditioner, and β:α is between [1 / 5, 1 / 3].

[0022] Through the above arrangement, a smaller air supply channel is provided, the static pressure formed by the diffuser section can be effectively utilized, a higher wind speed can be obtained, and the air supply distance can be increased.

[0023] In an optional embodiment, the end of the air outlet away from the upper diffuser section has a first limiting portion, and when the lower air guide plate is in a closed position, the lower end of the lower air guide plate is opposite to the first limiting portion, and the first limiting portion is used to limit the lower air guide plate from rotating counterclockwise.

[0024] Through the above arrangement, the first limiting portion can ensure that the lower air guide plate is closed in place.

[0025] In an optional embodiment, the air outlet has a second limiting portion at one end away from the lower air guide plate. When the upper air guide plate is in a closed position, the upper end of the upper air guide plate is opposite to the second limiting portion. The second limiting portion is used to limit the clockwise rotation of the upper air guide plate.

[0026] Through the above arrangement, the second limiting portion can ensure that the upper air guide plate is closed in place.

[0027] In an optional embodiment, the width dimension of the upper air guide plate is greater than the width dimension of the lower air guide plate.

[0028] Through the above arrangement, the upper air guide plate located on the upper side can disperse the airflow more widely, so that the air supply airflow covers a wider area. In addition, the wider upper air guide plate can reduce the wind speed to a certain extent, and can reduce the wind noise when the airflow passes through.

[0029] In an optional embodiment, a connection portion rotatably connected to the shell is provided on the inner side of the upper air guide plate, and the connection portion is located at the lower end of the upper air guide plate close to itself in the width direction of the upper air guide plate.

[0030] Through the above arrangement, the rotation axis of the upper air guide plate is relatively close to the lower end, and the center of gravity is lower. When a large air volume is output, the deformation or unstable movement of the upper air guide plate caused by its own weight can be reduced.

[0031] In an optional embodiment, a connection portion rotatably connected to the shell is provided on the inner side of the upper air guide plate, and a reinforcing rib is provided on the connection portion, and the reinforcing rib is also connected to the inner side of the upper air guide plate.

[0032] Through the above arrangement, the connection strength between the upper air guide plate and the connection portion can be strengthened by the reinforcing ribs. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The specific structure of an air conditioner provided by this embodiment and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0046] Please refer to Figure 1-Figure 4 An air conditioner 1 provided in an embodiment of the utility model includes a housing 100 , an upper diffuser section 500 , an upper air guide plate 200 and a lower air guide plate 300 .

[0047] The housing 100 is provided with an air outlet 110, an upper diffuser section 500 is provided at the air outlet 110, an upper air guide plate 200 is provided at the air outlet 110 and is rotatably connected to the housing 100, and a lower air guide plate 300 is provided at the air outlet 110 and is rotatably connected to the housing 100. The lower air guide plate 300 can be opened to a preset position, and when the lower air guide plate 300 is at the preset position, the distance between the upper end of the lower air guide plate 300 and the diffuser section is 0 to 10 mm, so as to guide the airflow of the air outlet 110 to be discharged downward.

[0048] It should be noted that the air conditioner 1 in this embodiment refers to an indoor hanging unit of the air conditioner. It can be understood that when the air conditioner 1 is hung on the wall and the lower air guide plate 300 is in the closed position, the higher end of the lower air guide plate 300 is the upper end of the lower air guide plate 300, and the lower end of the lower air guide plate 300 is the lower end of the lower air guide plate 300.

[0049] It can be understood that when the lower air guide plate 300 in this embodiment is rotated to the preset position, the distance between the upper end of the lower air guide plate 300 and the diffuser section is 0 to 10 mm. At this time, most of the airflow generated by the air conditioner 1 can be guided by the lower air guide plate 300 to discharge downward. It can be understood that since most of the airflow can be guided downward, during heating or cooling, the cold air or warm air can be delivered to the lower part of the room faster, accelerating the temperature change of the ground or the user's activity area, thereby improving the cooling or heating efficiency.

[0050] Furthermore, since the distance between the upper end of the lower air guide plate 300 and the diffuser section is in the range of 0 to 10 mm, most of the airflow generated by the air conditioner 1 can be guided by the lower air guide plate 300 to discharge downward. When the upper air guide plate 200 is closed, the airflow blowing toward the front air guide plate can be reduced, ensuring that most of the airflow flows along a predetermined path, avoiding airflow chaos, improving air supply efficiency, and also reducing noise caused by airflow chaos.

[0051] In some optional embodiments, when the lower air guide plate 300 is in the preset position, the upper end of the lower air guide plate 300 abuts against the upper diffuser section 500, that is, at this time, the distance between the upper end of the lower air guide plate 300 and the upper diffuser section 500 is 0. It can be understood that, since the upper end of the lower air guide plate 300 abuts against the upper diffuser section 500 when the lower air guide plate 300 is in the preset position, more airflow can be further guided downward by the lower air guide plate 300 to further improve the efficiency of cooling or heating.

[0052] Furthermore, when the upper end of the lower air guide plate 300 abuts against the upper diffuser section 500, most of the airflow generated by the air conditioner 1 will be blown out from below the air outlet 110, which can also avoid the situation where the airflow directly blows onto the user.

[0053] Of course, in some other embodiments, when the lower air guide plate 300 is in the preset position, the distance between the upper end of the lower air guide plate 300 and the upper diffuser section 500 can also be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.

[0054] Optionally, when the lower air guide plate 300 is in the preset position and the upper air guide plate 200 is in the closed position, the upper air guide plate 200 and the lower air guide plate 300 are used to guide the airflow blown out of the air outlet 110 to be discharged downward. That is to say, in this embodiment, when the upper air guide plate 200 is in the closed position, the lower air guide plate 300 can be rotated from the closed position to the preset position, and at this time, since the upper air guide plate 200 is in the closed state, the airflow generated by the air conditioner 1 will also be guided downward by the inner side of the upper air guide plate 200 to improve the delivery of cold air or warm air to the lower part of the room faster.

[0055] In detail, in order to reduce the interference between the upper air guide plate 200 and the lower air guide plate 300, when the upper air guide plate 200 and the lower air guide plate 300 are in the closed position, a preset gap is provided between the upper air guide plate 200 and the lower air guide plate 300.

[0056] The upper air guide plate 200 has a preset open position range. It can be understood that the preset open position range can be understood as a collection of various positions of the upper air guide plate 200 during the process of the upper air guide plate 200 rotating from the closed position to a preset angle. When the upper air guide plate 200 is in the preset open position range and the lower air guide plate 300 is in the closed position, the upper air guide plate 200 and the lower air guide plate 300 are used to guide the airflow blown out of the air outlet 110 upward.

[0057] It can be understood that when the lower air guide plate 300 is in the closed position, the inner side of the lower air guide plate 300 will guide part of the airflow generated by the air conditioner 1 upward.

[0058] It can be understood that in the cooling mode, the lower air guide plate 300 can be controlled to close, and the upper air guide plate 200 can be rotated within a preset open position range to guide the airflow blown out of the air outlet 110 to blow upward. Since the cold air flows from top to bottom, it can form natural convection with the rising hot air in the room, which can reduce the room temperature relatively evenly.

[0059] In some optional embodiments, the end of the air outlet 110 away from the upper air guide plate 200 is the lower air outlet, the angle between the extension direction of the upper diffuser section 500 close to the air outlet 110 and the preset straight line 400 passing through the lower air outlet is α, and when the lower air guide plate 300 is in the preset position, the angle between the direction from the upper end of the lower air guide plate 300 to the lower end of the lower air guide plate 300 and the preset straight line 400 is β, and the preset straight line 400 is parallel to the height direction of the air conditioner 1, and β:α is between [1 / 5, 1 / 3]. It should be noted that the height direction of the air conditioner can be understood as the height direction of the air conditioner when it is hung on the wall and is parallel to the vertical direction.

[0060] Optionally, β:α may be 1 / 5, 1 / 4 or 1 / 3.

[0061] That is, when the lower air guide plate 300 is in the preset position, the ratio of the air outlet range through the lower air guide plate 300 to the air outlet range of the entire air outlet 110 is between 1 / 5 and 1 / 3. Therefore, when the upper air guide plate 200 is in the closed state and the lower air guide plate 300 is in the preset position, there is a smaller air supply channel, which can effectively utilize the static pressure formed by the diffuser section, and can obtain a higher wind speed, thereby increasing the air supply distance.

[0062] Of course, in some other embodiments, β:α can also be 1 / 2.

[0063] Optionally, the air outlet 110 has a first limiting portion 111 at one end away from the diffuser section. When the lower air guide plate 300 is in the closed position, the lower end of the lower air guide plate 300 is opposite to the first limiting portion 111, and the first limiting portion 111 is used to limit the lower air guide plate 300 from rotating counterclockwise.

[0064] In detail, in this embodiment, the first limiting portion 111 is the lower air outlet end mentioned above. It can be understood that the lower air guide plate 300 can be ensured to be closed in place by setting the first limiting portion 111.

[0065] Optionally, the air outlet 110 has a second limiter 112 at one end away from the lower air guide plate 300. When the upper air guide plate 200 is in the closed position, the upper end of the upper air guide plate 200 is opposite to the second limiter 112. The second limiter 112 is used to limit the clockwise rotation of the upper air guide plate 200. Similarly, the second limiter 112 can ensure that the upper air guide plate 200 is closed in place.

[0066] It can be understood that when the upper air guide plate 200 in this embodiment is opened from the closed position, the opening direction is counterclockwise, and when the lower air guide plate 300 is opened from the closed position, the opening direction is clockwise.

[0067] Optionally, the width of the upper air guide plate 200 is greater than the width of the lower air guide plate 300. The upper air guide plate located on the upper side can disperse the airflow more widely, so that the air supply airflow covers a wider area. In addition, the wider upper air guide plate can reduce the wind speed to a certain extent, and can reduce the wind noise when the airflow passes through.

[0068] In detail, a connection portion 210 rotatably connected to the housing 100 is disposed on the inner side of the upper air guide plate 200 . In the width direction of the upper air guide plate 200 , the connection portion 210 is located at the lower end of the upper air guide plate 200 close to itself.

[0069] It should be noted that the inner side of the upper air guide plate 200 can be understood as the side close to the air outlet 110 when the upper air guide plate 200 is in a closed state, that is, the side opposite to the outer surface of the upper air guide plate 200 .

[0070] It should be noted that the lower end of the connecting portion 210 close to itself can be understood as the connecting portion 210 being closer to the lower end of the upper air guide plate 200 relative to the upper end of the upper air guide plate 200, and should not be understood as being arranged at the lower end of the upper air guide plate 200. Since the connecting portion 210 is located at the lower end of the upper air guide plate 200 close to itself, the rotation axis of the upper air guide plate 200 is relatively close to the lower end and the center of gravity is lower. When the air volume is large, the deformation or unstable movement of the upper air guide plate caused by its own weight can be reduced.

[0071] Of course, in some other embodiments, the connection portion 210 may also be disposed at other locations inside the upper air guide plate 200 .

[0072] Optionally, in order to improve the connection strength between the connection portion 210 and the upper air guide plate 200 , a reinforcing rib 220 is provided on the connection portion 210 , and the reinforcing rib 220 is also connected to the inner side of the upper air guide plate 200 .

[0073] In summary, the embodiment of the utility model provides an air conditioner 1, which includes a housing 100, an upper pressure diffuser 500, an upper air guide plate 200 and a lower air guide plate 300. The housing 100 is provided with an air outlet 110, the upper pressure diffuser 500 is provided at the air outlet 110, the upper air guide plate 200 is provided at the air outlet 110 and is rotatably connected to the housing 100, and the lower air guide plate 300 is provided at the air outlet 110 and is rotatably connected to the housing 100. The lower air guide plate 300 can be opened to a preset position, and when the lower air guide plate 300 is in the preset position, the distance between the upper end of the lower air guide plate 300 and the pressure diffuser is 0 to 10 mm, which is used to guide the airflow of the air outlet 110 to discharge downward. Since most of the airflow can be guided downward to discharge air, when heating or cooling, the cold air or the warm air can be delivered to the lower part of the room faster, accelerating the temperature change of the ground or the user's activity area, thereby improving the cooling or heating efficiency.

[0074] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
