Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0054] The following is combined Figures 1-8 The present invention describes an air supply control method, apparatus, and air conditioner for an air conditioner.

[0055] According to one embodiment of the present invention, referring to Figures 1-5 As shown, the indoor unit of the air conditioner provided by the present invention can be a cabinet unit, and the indoor unit mainly includes components such as a casing 100 and an air duct assembly 200.

[0056] The casing 100 is provided with a first air outlet 101, which can be circular in shape. When the first air outlet 101 is opened, the air that has been heated inside the casing 100 can be discharged through the first air outlet 101.

[0057] The air duct assembly 200 includes: a first cylinder 201 and a second cylinder 202. The first cylinder 201 and the second cylinder 202 can be cylindrical. The first cylinder 201 is disposed inside the housing 100 and is located at the first air outlet 101. The center of the first air outlet 101 can be located on the central axis of the first cylinder 201.

[0058] The second cylinder 202 is slidably fitted onto the outer wall of the first cylinder 201, meaning the second cylinder 202 can slide relative to the first cylinder 201 to extend and retract at the first air outlet 101. A second air inlet 203 is provided in the middle of the second cylinder 202, and the first cylinder 201 is adapted to open and close the second air inlet 203. When the second air inlet 203 is open, the air that has undergone heat exchange inside the casing 100 can enter the first cylinder 201 through the second air inlet 203. Specifically, when the second cylinder 202 extends out of the casing 100 through the first air outlet 101, the wall of the first cylinder 201 blocks the second air inlet 203, thus closing the second air inlet 203. When the second cylinder 202 retracts into the casing 100 through the first air outlet 101, the wall of the first cylinder 201 is misaligned with the second air inlet 203, thus opening the second air inlet 203.

[0059] The outer end of the second cylinder 202 is provided with a second air outlet 204, and the edge of the second air outlet 204 is provided with a damper 205. The damper 205 is a flanged structure integrally formed on the second cylinder 202, and the damper 205 is suitable for opening and closing the first air outlet 101. Specifically, when the second cylinder 202 extends out of the housing 100 through the first air outlet 101, the damper 205 moves away from the first air outlet 101, thereby opening the first air outlet 101; when the second cylinder 202 retracts into the housing 100 through the first air outlet 101, the damper 205 approaches the first air outlet 101 and blocks and seals it, thereby closing the first air outlet 101.

[0060] The following is a general description of the air supply modes of the indoor unit of the air conditioner provided in the embodiments of the present invention, which mainly include: short-distance air supply mode, long-distance air supply mode and uniform air supply mode.

[0061] Near-field air supply mode: such as Figure 3 and Figure 4 As shown, the second cylinder 202 extends forward from the housing 100 through the first air outlet 101. The wall of the first cylinder 201 completely blocks the second air inlet 203, and the second air inlet 203 is closed. At the same time, the damper 205 moves away from the first air outlet 101, thereby opening the first air outlet 101. The air that has been heated inside the housing 100 is discharged circumferentially through the first air outlet 101, achieving a close-range and gentle air supply effect.

[0062] Long-distance air supply mode: such as Figure 2 and Figure 5 As shown, the second cylinder 202 retracts into the housing 100 through the first air outlet 101. The wall of the first cylinder 201 is misaligned with the second air inlet 203, and the second air inlet 203 is opened. At this time, the damper 205 approaches the first air outlet 101 and blocks and seals it, thereby closing the first air outlet 101. The air that has been heated in the housing 100 enters the first cylinder 201 through the second air inlet 203 and is discharged forward axially through the second air outlet 204 of the second cylinder 202, achieving a long-distance air supply effect.

[0063] It is understandable that when the air conditioner is turned off, the second cylinder 202 retracts into the casing 100 through the first air outlet 101.

[0064] Uniform air supply mode: The second cylinder 202 extends forward from the casing 100 through the first air outlet 101, and the extension distance is less than the extension distance in the close-range air supply mode. The wall of the first cylinder 201 partially blocks the second air inlet 203, and the second air inlet 203 is not fully opened. At the same time, the damper 205 moves away from the first air outlet 101, thereby opening the first air outlet 101. The air that has been heated inside the casing 100 is discharged simultaneously through the first air outlet 101 and the second air outlet 204, realizing simultaneous air supply in multiple directions such as axial and circumferential, thereby improving the uniformity of indoor temperature.

[0065] Therefore, the indoor unit of the air conditioner provided in this embodiment of the invention can adjust the air supply direction and air supply distance to realize multiple air supply modes, thereby meeting the needs of different users, improving the user experience, and has the characteristics of simple structure, stability and reliability.

[0066] According to one embodiment of the present invention, the air duct assembly further includes: a driver, which is disposed inside the housing 100 and is located on the opposite side of the first air outlet 101. For example, when the first air outlet 101 is located on the front side of the housing 100, the driver is located on the rear side of the housing 100; the driving end of the driver is drivenly connected to the second cylinder 202 for driving the second cylinder 202 to move telescopically.

[0067] The specific type of the actuator in this invention is not particularly limited, as long as it can drive the second cylinder 202 to move linearly. For example, the actuator can be a linear motor, an electric push rod, or other linear drive device.

[0068] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the outer wall of the second cylinder 202 is provided with a connecting seat 206, and the driving end of the driver is connected to the connecting seat 206.

[0069] According to one embodiment of the present invention, referring to Figure 4 As shown, the air duct assembly 200 further includes: a third cylinder 207, which may be cylindrical in shape. The third cylinder 207 is disposed inside the housing 100 and is located on the opposite side of the first air outlet 101. For example, when the first air outlet 101 is located on the front side of the housing 100, the third cylinder 207 is located on the rear side of the housing 100, and the third cylinder 207 is spaced from the first cylinder 201 for flow passage; the inner end of the second cylinder 202 is slidably sleeved on the outer wall of the third cylinder 207 for guiding the second cylinder 202 and improving the movement stability of the second cylinder 202.

[0070] According to one embodiment of the present invention, a plurality of actuators are arranged around the outer side of the third cylinder 207, and correspondingly, a plurality of connecting seats 206 are arranged around the outer wall of the second cylinder 202, which can effectively improve the movement stability of the second cylinder 202.

[0071] According to one embodiment of the present invention, referring to Figure 2 As shown, the second cylinder 202 is provided with multiple annular second air inlets 203, which can increase the air intake volume.

[0072] According to one embodiment of the present invention, referring to Figure 1 As shown, the outer diameter of the second cylinder 202 is smaller than the diameter of the first air outlet 101, so that when the first air outlet 101 is opened, the air that has undergone heat exchange inside the casing 100 can be discharged through the first air outlet 101.

[0073] According to one embodiment of the present invention, a first air outlet 101 is provided on the upper front side of the housing 100, and a first air inlet 102 is provided on the lower left and right sides of the housing 100.

[0074] Furthermore, referring to Figure 4 and Figure 5 As shown, the housing 100 is equipped with a fan 103 and a heat exchanger 104. The fan 103 is located at the first air inlet 102, and the heat exchanger 104 is located between the fan 103 and the air duct assembly 200.

[0075] Specifically, when the fan 103 rotates, it draws indoor air into the casing 100 through the first air inlet 102 and exchanges heat through the heat exchanger 104. The air after heat exchange can be discharged according to actual needs. For details, please refer to the aforementioned air supply mode. It will not be elaborated here.

[0076] According to one embodiment of the present invention, the heat exchanger 104 is V-shaped, with the open end of the heat exchanger 104 facing the air outlet side of the fan 103. This design can effectively improve the heat exchange effect.

[0077] The specific type of the fan 103 of the present invention is not particularly limited; for example, it can be a centrifugal fan.

[0078] In addition, the air conditioner also includes an outdoor unit, which mainly includes components such as a compressor and an outdoor heat exchanger. The connection method between the outdoor unit and the indoor unit is a conventional technology in this field and will not be described in detail here.

[0079] The air supply control method of the air conditioner according to the above embodiments of the present invention will be described below.

[0080] According to one embodiment of the present invention, referring to Figure 6 As shown, the present invention provides an air supply control method for an air conditioner, which mainly includes the following steps:

[0081] S100. Obtain the indoor temperature while the air conditioner is running.

[0082] Specifically, when the air conditioner is turned on, the indoor temperature can be obtained in real time through a temperature sensor.

[0083] S200: Based on the difference between the indoor temperature and the target set temperature, control the extension and retraction of the second cylinder 202 to adjust the opening and closing of the first air outlet 101 and the second air inlet 203.

[0084] Specifically, when the difference between the indoor temperature and the target set temperature is greater than or equal to the set value, it indicates that the temperature difference is large. At this time, the second cylinder 202 is retracted into the casing 100 to open the second air inlet 203 and close the first air outlet 101. The air that has been heated in the casing 100 enters the first cylinder 201 through the second air inlet 203 and is directly discharged forward through the second air outlet 204 of the second cylinder 202, realizing long-distance air delivery and achieving the effect of rapid cooling.

[0085] When the difference between the indoor temperature and the target set temperature is less than the set value, it indicates that the temperature difference is small. At this time, the second cylinder 202 is controlled to extend out of the casing 100 to simultaneously open the second air inlet 203 and the first air outlet 101. The air that has undergone heat exchange in the casing 100 is discharged simultaneously through the first air outlet 101 and the second air outlet 204 to ensure the uniformity of the indoor temperature.

[0086] Furthermore, when it is determined that the difference between the indoor temperature and the target set temperature is less than the set value, the fan speed 103 inside the casing 100 can be reduced to the target set speed, and / or the compressor frequency of the outdoor unit of the air conditioner can be reduced to the target set frequency, thereby reducing the operating energy consumption of the air conditioner while maintaining a stable indoor ambient temperature.

[0087] Therefore, the air supply control method for the air conditioner provided in this embodiment of the invention can adjust the opening and closing of the first air outlet 101 and the second air inlet 203 by controlling the extension and retraction of the second cylinder 202, thereby adjusting the air supply direction and air supply distance, realizing multiple air supply modes, meeting different heat exchange needs, and effectively improving the user experience.

[0088] According to one embodiment of the present invention, after determining that the difference between the indoor temperature and the target set temperature is less than the set value, reducing the speed of the fan 103 inside the casing 100 to the target set speed, and / or reducing the compressor frequency of the outdoor unit of the air conditioner to the target set frequency, the method further includes: obtaining the location of the indoor user; and controlling the telescopic movement of the second cylinder 202 according to the location of the indoor user.

[0089] Specifically, after determining that the difference between the indoor temperature and the target set temperature is less than the set value, the fan speed 103 inside the casing 100 is reduced to the target set speed, and / or the compressor frequency of the outdoor unit of the air conditioner is reduced to the target set frequency and operated for a preset time, the indoor temperature is in a state that is close to and uniformly stable with respect to the target set temperature. At this time, the location of the indoor user can be detected by an infrared sensor.

[0090] When it is determined that the distance between the indoor user and the indoor unit is less than or equal to a preset distance and outside the preset air outlet angle range of the indoor unit, it indicates that the indoor user is close to the indoor unit and outside the air outlet radiation range of the indoor unit. At this time, the second cylinder 202 is retracted into the casing 100 to open the second air inlet 203 and close the first air outlet 101, achieving a long-distance air supply without a draft. The preset air outlet angle range can be the maximum air outlet radiation range of the indoor unit.

[0091] When it is determined that the distance between the indoor user and the indoor unit is greater than the preset distance, it means that the indoor user is far away from the indoor unit. At this time, the second cylinder 202 is controlled to extend out of the casing 100 to close the second air inlet 203 and open the first air outlet 101, so as to achieve the effect of close-range air supply without wind.

[0092] Therefore, embodiments of the present invention can achieve a windless effect when the indoor temperature is close to and uniformly stable with respect to the target set temperature, thus avoiding the phenomenon of wind blowing on people and effectively improving the user experience.

[0093] According to an embodiment of the present invention, the air supply control method further includes: determining that the distance between the indoor user and the indoor unit is less than or equal to a preset distance and within the preset air outlet angle range of the indoor unit, indicating that the indoor user is close to the indoor unit and within the air outlet radiation range of the indoor unit, and sending a wind sensing request command to the user terminal of the indoor user; and controlling the telescopic movement of the second cylinder 202 according to the wind sensing feedback command sent by the user terminal.

[0094] Specifically, if a user terminal sends a no-wind instruction, a request instruction to leave the preset air outlet angle range is sent to the user terminal. Upon receiving a confirmation instruction from the user terminal, indicating that the user has left the air outlet radiation range of the indoor unit, the second cylinder 202 is retracted into the casing 100 to open the second air inlet 203 and close the first air outlet 101, thereby achieving the effect of long-distance air supply without wind.

[0095] If a user feedback indicates that there is a wind sensation, the second cylinder 202 can be extended out of the casing 100 to close the second air inlet 203 and open the first air outlet 101, thereby achieving a gentle, close-range air delivery effect.

[0096] Therefore, the air supply control method for air conditioners provided in this embodiment of the invention can enable interaction between the user and the air conditioner, and adjust the air supply mode according to the user's independent needs, thereby meeting the user's airflow requirements and effectively improving the user experience.

[0097] According to one embodiment of the present invention, the air supply control method of the present invention further includes: controlling the second cylinder 202 to retract into the housing 100 when the air conditioner is turned off.

[0098] The air supply control device for an air conditioner provided by the present invention is described below. The air supply control device for an air conditioner described below can be referred to in correspondence with the air supply control method for an air conditioner described above.

[0099] According to one embodiment of the present invention, referring to Figure 7 As shown, the present invention also provides an air supply control device for an air conditioner according to the above embodiment, mainly comprising: an acquisition module 710 and a control module 720. The acquisition module 710 is used to acquire the indoor temperature when the air conditioner is turned on and running; the control module 720 is used to control the extension and retraction of the second cylinder 202 according to the difference between the indoor temperature and the target set temperature, so as to adjust the opening and closing of the first air outlet 101 and the second air inlet 203.

[0100] The air supply control device for air conditioners provided by this invention can adjust the air supply direction and distance of the indoor unit of the air conditioner, realize multiple air supply modes, meet different heat exchange needs, and effectively improve the user experience.

Figure 8 As shown, the air conditioner may include a processor 810, a communication interface 820, a memory 830, and a communication bus 840. The processor 810, communication interface 820, and memory 830 communicate with each other via the communication bus 840. The processor 810 can call logic instructions in the memory 830 to execute an air supply control method for the air conditioner. This method includes: acquiring the indoor temperature when the air conditioner is running; and controlling the extension and retraction of the second cylinder based on the difference between the indoor temperature and the target set temperature to adjust the opening and closing of the first air outlet and the second air inlet.

[0102] Furthermore, the logical instructions in the aforementioned memory 830 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, essentially, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.
