Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method for an air conditioner. Background Technology

[0002] With the widespread use of air conditioning, users have increasingly higher demands for the comfort and health benefits of airflow. Traditional floor-standing air conditioners have a fixed airflow volume, blowing cold air directly at people, making "air conditioning sickness" the biggest problem for users. In the traditional floor-standing air conditioner's airflow design, due to the conflict between airflow and noise, the maximum airflow is limited to a certain range. The cold air blown out by the air conditioner is relatively low in temperature, and blowing it directly at people causes physical discomfort, affecting the user experience. Traditional solutions to address the issue of cold air blowing directly at people mainly involve the airflow at the air outlet mixing with the indoor air at the outlet. While this achieves a mixing effect of hot and cold air, the airflow volume is relatively small, and the mixing effect is not very significant. Summary of the Invention

The temperature of the mixed airflow is closer to room temperature than the heat exchange airflow, resulting in a gentler breeze and higher comfort.

[0080] The following reference Figures 1 to 10 The control method of the tuner in the embodiments of the present invention will be described.

[0081] Figure 1 This is a schematic front view of a vertical air conditioner indoor unit according to an embodiment of the present invention, with reference to... Figures 2 to 10 In the control method of the air conditioner according to an embodiment of the present invention, the air conditioner includes a first air outlet column 10 and a second air outlet column 20. The first air outlet column 10 is vertically columnar, and a first air outlet 11 for blowing out heat exchange airflow is opened on the front side of the first air outlet column 10. The second air outlet column 20 is vertically columnar, and a second air outlet 21 for blowing out non-heat exchange airflow is opened on the front side of the second air outlet column 20, and a second air guide plate 22 is provided at the second air outlet 21. The second air outlet column 20 is disposed on one side laterally of the first air outlet column 10. The second air outlet column 20 and the first air outlet column 10 are spaced apart, and the second air outlet column 20 and the first air outlet column 10 form an air intake interval 16. A third air guide plate 17 is provided at the front end of the air intake interval 16. The air conditioner has a first air supply mode, and the control method of the air conditioner includes executing the first air supply mode. Figure 9 As shown, the first air supply mode includes: rotating the front end of the second air guide plate 22 toward the first air outlet column 10 to a first preset position, so that part or all of the airflow from the second air outlet 21 is supplied in a first direction. Rotating the front end of the third air guide plate 17 toward the first air outlet column 10 to a second preset position, so that part or all of the airflow from the air intake interval is supplied in a second direction. The angle between the first direction and the vertical plane extending in the front-back direction is greater than the angle between the second direction and the vertical plane extending in the front-back direction. The first air outlet 11 supplies air according to a first preset air volume or a first preset air velocity. The second air outlet 21 supplies air according to a second preset air volume or a second preset air velocity, where the second preset air volume is less than the first preset air volume, and the air velocity corresponding to the second preset air volume is greater than the air velocity corresponding to the first preset air volume. The second preset air velocity is greater than the first preset air velocity, and the air volume corresponding to the second preset air velocity is less than the air volume corresponding to the first preset air velocity.

[0082] The dual air outlet columns significantly increase the total airflow of the air conditioner, dramatically accelerating room heat exchange. The aforementioned control method ensures that the airflow from the second air outlet 21 and the induced draft interval 16 is directed towards the first air outlet column 10. Furthermore, the airflow volume or velocity setting of the second air outlet column 20, without affecting the cooling effect, facilitates thorough mixing of the non-heat-exchange airflow from the second air outlet column 20 with the heat-exchange airflow from the first air outlet column 10. The temperature of the mixed airflow is closer to room temperature than the heat-exchange airflow, resulting in a gentler breeze and greater comfort.

[0083] Further, in some embodiments of the present invention, the first preset position is where the angle between the second air guide plate 22 and the front side of the vertical plane extending in the front-rear direction is 20° to 40°, preferably 30°. The second preset position is where the angle between the third air guide plate 17 and the front side of the vertical plane extending in the front-rear direction is 5° to 15°, preferably 10°. The first preset air volume is 500 m³ / h to 700 m³ / h, preferably 600 m³ / h. The first preset wind speed is 1.5 m / s to 1.7 m / s, preferably 1.6 m / s. The second preset air volume is 300 m³ / h to 500 m³ / h, preferably 400 m³ / h. The second preset wind speed is 3.3 m / s to 3.7 m / s, preferably 3.5 m / s. The airflow and wind speed settings described above not only ensure a certain cooling capacity but also provide user comfort.

[0084] In some embodiments of the present invention, such as Figure 2 As shown, the control method of the air conditioner further includes: acquiring the indoor ambient temperature. When the difference between the indoor ambient temperature and the set temperature is less than or equal to a first preset difference, acquiring the temperature of the airflow at a preset distance in front of the first air outlet 11. When the temperature of the airflow at the preset distance in front of the first air outlet 11 is less than or equal to the first preset value, or when the temperature of the airflow at the preset distance in front of the first air outlet 11 is greater than or equal to a second preset value and less than or equal to the first preset value, executing a second air supply mode. The second air supply mode includes: rotating the front end of the third air guide plate 17 to a third preset position to deliver part or all of the airflow from the air intake interval forward. Delivering air from the first air outlet 11 according to a third preset air volume or a third preset air velocity to reduce the airflow of the first air outlet 11. Delivering air from the second air outlet 21 according to a fourth preset air volume or a fourth preset air velocity to reduce the airflow of the second air outlet 21. The fourth preset air volume is less than the third preset air volume. The airflow corresponding to the fourth preset air velocity is less than the airflow corresponding to the third preset air velocity.

[0085] Since the difference between the indoor ambient temperature and the set temperature is less than or equal to the first preset difference, and the temperature of the airflow at the preset distance is also kept within a certain range, reducing the air volume or wind speed of the first air outlet 11 and the second air outlet 21 can achieve gentle airflow and provide a cool but not cold user experience.

[0086] Further, in some embodiments of the present invention, the first preset difference is 1° to 3°, preferably 2°. The first preset value is 22° to 25°, preferably 23.5°. The second preset value is 21° to 24°, preferably 22.5°. The third preset position is that the third air guide plate 17 is vertically arranged along the front-to-back direction. The third preset air volume is 300 m³ / h to 500 m³ / h, preferably 400 m³ / h. The fourth preset air volume is 200 m³ / h to 400 m³ / h, preferably 300 m³ / h. The third preset wind speed is 0.75 m / s to 1.5 m / s, preferably 1 m / s. The fourth preset wind speed is 2.5 m / s to 3.5 m / s, preferably 2.6 m / s. The preset distance in front is 0.5 m to 1.5 m, preferably 1 m.

[0087] In some embodiments of the present invention, such as Figure 1 As shown, the control method for the air conditioner further includes: acquiring the indoor ambient temperature. When the difference between the indoor ambient temperature and the set temperature is less than or equal to a second preset difference, a first air supply mode is initiated. At this time, since the difference between the indoor ambient temperature and the set temperature is less than or equal to the second preset difference, the first air supply mode can deliver an airflow that is a mixture of non-heat exchange airflow and heat exchange airflow, gradually causing the indoor ambient temperature to approach the set temperature. Further, in some embodiments of the present invention, the second preset difference is 8° to 12°, preferably 10°.

[0088] In some embodiments of the present invention, such as Figure 3 As shown, when the difference between the indoor ambient temperature and the set temperature is greater than the second preset difference, the third air supply mode is executed. The third air supply mode includes only actively supplying air through the first air outlet 11. At this time, the difference between the indoor ambient temperature and the set temperature is large, and only controlling the heat exchange airflow of the first air outlet 11 to be blown out can promote the indoor ambient temperature to drop as quickly as possible, at least to meet the user's cooling needs.

[0089] Furthermore, in some embodiments of the present invention, a first air guide plate 12 is provided at the first air outlet 11. The third air supply mode further includes: rotating the front end of the first air guide plate 12 to a fourth preset position, so that the first air outlet 11 supplies air according to a fifth preset air volume or according to a fifth preset wind speed.

[0090] The fifth preset air volume is greater than the first preset air volume. The air volume corresponding to the fifth preset wind speed is greater than the air volume corresponding to the first preset wind speed. The fifth preset air volume is 1200 m³ / h to 1600 m³ / h, preferably 1400 m³ / h, and the fifth preset wind speed is 4 m / s to 5 m / s, preferably 4.5 m / s.

[0091] In this embodiment, in order to reduce the indoor ambient temperature as quickly as possible, while controlling the heat exchange airflow to be blown out only from the first air outlet 11, the air volume or air delivery speed of the first air outlet 11 is also increased.

[0092] Furthermore, in some embodiments of the present invention, such as Figure 10 As shown, the first air guide plate 12 includes a large air guide plate 121 and a small air guide plate 122 arranged laterally adjacent to each other, with the large air guide plate 121 close to the second air outlet column 20. The fourth preset position can also be that the large air guide plate 121 is vertically arranged along the front-to-back direction, and the small air guide plate 122 is arranged laterally. By reducing the air outlet area of ​​the first air outlet 11 (which can also be called the effective flow area), the air velocity is increased, thereby accelerating the reduction of the indoor ambient temperature. Alternatively, both the large air guide plate 121 and the small air guide plate 122 at the fourth preset position have a certain angle with the vertical plane extending along the front-to-back direction, so that the first air guide plate 12 partially covers the first air outlet, reducing the air outlet area and increasing the air velocity at the first air outlet. In this case, when the air volume of the first air outlet 11 is 1400 m³ / h, the air velocity can reach 6.4 m / s, resulting in a more significant cooling effect.

[0093] In some embodiments of the present invention, the third air supply mode further includes: obtaining whether there is a person within a preset distance in front of the first air outlet 11; when there is a person within a preset distance in front of the first air outlet 11, rotating the front end of the first air guide plate 12 to a fifth preset position to expand the air outlet area of ​​the first air outlet 11, thereby reducing the air supply speed of the first air outlet 11.

[0094] The fifth preset position is where the first air guide plate 12 is set vertically along the front-to-back direction. Compared with the fourth preset position, this can increase the air outlet area of ​​the first air outlet 11, reduce the wind speed, and minimize the direct airflow to people.

[0095] In some embodiments of the present invention, after executing the first air supply mode, the method further includes: first, bringing the indoor ambient temperature to a set temperature, and then acquiring the temperature of the airflow at a preset distance in front of the first air outlet 11. When the temperature of the airflow at the preset distance in front of the first air outlet 11 is less than or equal to a first preset value, or when the temperature of the airflow at the preset distance in front of the first air outlet 11 is greater than or equal to a second preset value and less than or equal to the first preset value, the second air supply mode is executed. Then, the acquisition of the indoor ambient temperature is repeated cyclically. When the difference between the indoor ambient temperature and the set temperature is less than or equal to a first preset difference, the temperature of the airflow at the preset distance in front of the first air outlet 11 is acquired. When the temperature of the airflow at the preset distance in front of the first air outlet 11 is less than or equal to the first preset value, or when the temperature of the airflow at the preset distance in front of the first air outlet 11 is greater than or equal to the second preset value and less than or equal to the first preset value, the second air supply mode is executed.

[0096] In other embodiments of the present invention, after executing the first air supply mode, the system directly enters a state where the difference between the indoor ambient temperature and the set temperature is less than or equal to a first preset difference, and obtains the temperature of the airflow at a preset distance in front of the first air outlet 11. The second air supply mode is executed when the temperature of the airflow at the preset distance in front of the first air outlet 11 is less than or equal to a first preset value, or when the temperature of the airflow at the preset distance in front of the first air outlet 11 is greater than or equal to a second preset value and less than or equal to the first preset value.

[0097] In some embodiments of the invention, when the temperature of the airflow at a preset distance in front of the first air outlet 11 is less than or equal to a first preset value, the system enters a first air supply mode or a third air supply mode based on the relationship between the difference between the indoor ambient temperature and the set temperature and a second preset difference. When the difference between the indoor ambient temperature and the set temperature is greater than the first preset difference, the system enters a first air supply mode or a third air supply mode based on the relationship between the difference between the indoor ambient temperature and the set temperature and a second preset difference.

[0098] In some embodiments of the present invention, the second air supply mode further includes: acquiring indoor environmental quality. Based on a received user's fresh air demand activation command or based on environmental quality, the air conditioner is controlled to blow out fresh air by ensuring that the airflow from the second air outlet 21 consists entirely or partially of fresh air. When indoor environmental quality is poor, the second air outlet 21 can be controlled to blow out fresh air to improve indoor environmental quality. Of course, in some embodiments, fresh air can be continuously supplied.

[0099] In some embodiments of the present invention, such as Figure 4 , Figure 5As shown, a first air inlet 13 communicating with a first air outlet 11 is provided on the peripheral wall of the first air outlet column 10, such as on the side wall and rear wall of the first air outlet column 10. A heat exchanger 15 and a heat exchange fan 14 are provided inside the first air outlet column 10. The heat exchange fan 14 guides indoor air into the first air inlet 13, passes through the heat exchanger 15, and is blown out from the first air outlet 11. A second air inlet 23 communicating with a second air outlet 21 is provided on the peripheral wall of the second air outlet column 20, such as on the side wall of the second air outlet column 20. A cross-flow fan 24 is provided inside the second air outlet column 20, and a third air inlet 32 ​​communicating with the second air outlet 21 is opened at the lower end of the second air outlet column 20. The air conditioner also includes a lower casing 30, with the first air outlet column 10 and the second air outlet column 20 located at the top of the lower casing 30. The lower shell 30 has a fresh air inlet and a fresh air outlet on its perimeter wall. The fresh air inlet is connected to the third air inlet 32 ​​or the fresh air outlet via a diversion device. A fan is installed inside the lower shell 30 to drive fresh air from the fresh air inlet through the third air inlet into the second air outlet or the fresh air outlet. A damper is installed at the second air inlet 21, the third air inlet 32, or the fresh air inlet. The diversion device can adjust the ratio of fresh air entering the fresh air outlet and the third air inlet 32. It should be noted that the second air outlet is prioritized to output the maximum amount of fresh air. When the required fresh air volume is greater than the current maximum required air volume of the second air outlet, the fresh air outlet can be used to output fresh air. In this case, the second air inlet 21 can be closed, and the second air outlet is only used for fresh air output. Of course, in some embodiments, a separate fresh air outlet is not provided. During the entire control process, the amount of fresh air entering cannot exceed the current maximum required air volume of the second air outlet. For example, in some embodiments, a constant fresh air volume is input.

[0100] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
