Description

Technical Field

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

[0002] With rapid social development and the continuous improvement of people's living standards, people's demands for quality of life are also increasing. Air conditioners, as important electrical appliances, are gradually entering thousands of households and are widely used. Traditional air conditioners stop the compressor when the room temperature reaches the user's set temperature (i.e., they shut off when the set temperature is reached). Some air conditioners with inverter technology, while not completely shutting off, will reduce the frequency when the room temperature reaches the set temperature and increase the frequency when the temperature rises. If the room temperature fluctuates frequently, such as when the room is exposed to direct sunlight in hot weather, the air conditioner will frequently start and stop the compressor or cause the compressor to continuously increase or decrease its frequency. Frequent shutdowns or frequency adjustments at the set temperature can cause large temperature fluctuations, sudden changes in temperature, and discontinuous noise from the air conditioner, seriously affecting the compressor's lifespan and greatly reducing the air conditioner's reliability and safety. Summary of the Invention

[0003] Based on the above background, one objective of the present invention is to provide a control method for an air conditioner that at least solves some of the problems mentioned above.

[0004] Another objective of the present invention is to provide an air conditioner that solves the above-mentioned problems.

[0005] In particular, according to a first aspect of the present invention, the present invention provides a control method for an air conditioner, wherein the air conditioner includes a first air outlet column and a second air outlet column arranged horizontally at intervals, and heat exchangers are respectively disposed in the first air outlet column and the second air outlet column.

[0006] The control method for the air conditioner includes: controlling the air conditioner to start; detecting the ambient temperature of the air conditioner's operating environment; determining whether the difference between the ambient temperature and the air conditioner's set temperature is greater than a preset temperature difference threshold; if so, controlling both the first and second air outlet columns to start heat exchange and blowing out heat exchange airflow respectively; if not, controlling the first air outlet column to start heat exchange and blowing out heat exchange airflow, and controlling the second air outlet column to stop heat exchange and blow out ambient temperature airflow.

[0007] Optionally, after the step of controlling the air conditioner to start, the air conditioner control method further includes: controlling the first air outlet column to outlet air in a preset direction; and controlling the second air outlet column to swing horizontally back and forth to outlet air.

[0008] Optionally, the step of controlling the first air outlet column to outlet air in a preset direction includes: acquiring the environmental characteristics of the air conditioner's operating environment; determining the preset direction based on the environmental characteristics; adjusting the outlet direction of the first air outlet column to the preset direction, so that the heat exchange airflow blown by the first air outlet column forms an air curtain in the preset direction and separates the temperature regulation space within the air conditioner's operating environment.

[0009] Optionally, the step of determining the preset direction based on environmental characteristics includes: identifying the high-impact area with the largest temperature difference from the set temperature of the air conditioner, and the location of the side wall in the operating environment that is far from the air conditioner and adjacent to the high-impact area; setting the direction of the air outlet of the first air outlet column facing the side wall as the preset direction; or setting the direction of the air outlet of the first air outlet column towards the direction between the side wall and the high-impact area as the preset direction.

[0010] Optionally, the step of controlling the second air outlet column to swing laterally includes: controlling the second air outlet column to swing laterally and swing towards the temperature-controlled space to outlet air.

[0011] Optionally, before the step of controlling the air conditioner to start, the air conditioner control method may further include: obtaining the positioning distance between the user and the air conditioner and a preset distance threshold; determining whether the positioning distance is less than the distance threshold; if so, controlling the air conditioner to start.

[0012] Optionally, the step of obtaining the location distance between the user and the air conditioner includes: obtaining the location of the device connected to the air conditioner; and calculating the location distance based on the location of the device connected to the air conditioner.

[0013] Alternatively, devices that can be connected to the air conditioner include: a mobile phone or a smart bracelet.

[0014] Optionally, when the difference between the ambient temperature and the set temperature of the air conditioner is greater than the temperature difference threshold, the control method of the air conditioner further includes: when the difference between the ambient temperature and the set temperature is equal to the temperature difference threshold, detecting the compressor frequency of the air conditioner and obtaining a preset frequency threshold; determining whether the compressor frequency is greater than the frequency threshold; if so, controlling the compressor to reduce its frequency to the frequency threshold.

[0015] According to another aspect of the present invention, an air conditioner is provided, comprising a first air outlet column and a second air outlet column arranged horizontally at intervals, wherein heat exchangers are respectively disposed within the first air outlet column and the second air outlet column. The air conditioner further comprises a control device, which includes a processor and a memory, wherein the memory stores a control program, and the control program, when executed by the processor, is used to implement the control method of any of the above-described air conditioners.

[0016] The air conditioner of the present invention includes a first air outlet column and a second air outlet column arranged horizontally at intervals, and heat exchangers are respectively arranged in the first and second air outlet columns, so that the first and second air outlet columns can independently discharge air without interference and the airflow can be controlled to determine whether the airflow is a heat exchange airflow. According to the control method of the air conditioner of the present invention, when the temperature difference between the ambient temperature and the set temperature of the air conditioner is large, the first and second air outlet columns simultaneously blow heat exchange airflow to reduce the temperature difference; when the temperature difference between the ambient temperature and the set temperature of the air conditioner is small, only the first air outlet column blows heat exchange airflow to provide cooling or heating, while the second air outlet column blows ambient warm airflow to increase air circulation. When the ambient temperature approaches the set temperature of the air conditioner, with the help of the cooling or heating provided by the first air outlet column and the ambient warm airflow blown by the second air outlet column, the ambient temperature can be better maintained near the set temperature of the air conditioner, and the air conditioner compressor only needs to continuously provide a certain amount of cooling or heating to the first air outlet column, without the need for frequent start-stop or continuous frequency conversion.

[0017] Furthermore, the first air outlet column is directed to a preset direction, which corresponds to the area that has a significant impact on the ambient temperature. Through the air curtain formed by the directional airflow from the first air outlet column, this area is isolated from the temperature-controlled space, thereby significantly reducing the area's influence on the temperature of the temperature-controlled space and making the temperature within the temperature-controlled space more stable.

[0018] Furthermore, the air conditioner also has an automatic start-up function.

[0019] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0031] Figure 1 This is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0032] refer to Figure 1 As shown, the air conditioner 10 in this embodiment includes a first air outlet column 12 and a second air outlet column 14 arranged horizontally at intervals. Heat exchangers are respectively provided in the first air outlet column 12 and the second air outlet column 14, so that the first air outlet column 12 and the second air outlet column 14 can independently outlet air without interfering with each other and control whether the outlet airflow is a heat exchange airflow.

[0033] exist Figure 1In the air conditioner 10 shown, the first air outlet column 12 and the second air outlet column 14 are fixed relative to the housing of the air conditioner 10, but each has a longitudinally extending air guide plate at its respective air outlet. By adjusting the rotation position of the air guide plate, the first air outlet column 12 and the second air outlet column 14 can adjust their air outlet direction. Meanwhile, in some alternative embodiments, the first air outlet column 12 and / or the second air outlet column 14 are rotatably mounted on the air conditioner 10, thereby allowing the air outlet direction to be adjusted by rotating the column. It is understood that the air outlets of the first air outlet column 12 and the second air outlet column 14 are located on their side wall surface rather than their top or bottom surface, and the air outlets are generally as follows... Figure 1 It is schematically formed along the length direction of the first air outlet column 12 and the second air outlet column 14.

[0034] Figure 2 This is a flowchart illustrating a control method for an air conditioner 10 according to an embodiment of the present invention.

[0035] refer to Figure 2 As shown, the control method of the air conditioner 10 generally includes:

[0036] Step S202: Control the air conditioner 10 to start;

[0037] Step S204: Detect the ambient temperature of the operating environment of the air conditioner 10;

[0038] Step S206: Determine whether the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than a preset temperature difference threshold.

[0039] If so, execute step S208 to control both the first air outlet column 12 and the second air outlet column 14 to start heat exchange and blow out heat exchange airflow respectively;

[0040] If not, proceed to step S210, control the first air outlet column 12 to start heat exchange and blow out heat exchange airflow, and control the second air outlet column 14 to stop heat exchange and blow out ambient temperature airflow.

[0041] The preset temperature difference threshold can be used to define the ambient temperature when the second air outlet column 14 of the air conditioner 10 switches between blowing heat exchange airflow and blowing ambient temperature airflow. The set temperature of the air conditioner 10, as the temperature actively set by the user, often reflects the user's ideal ambient temperature for the current environment. When the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than the temperature threshold, the first air outlet column 12 and the second air outlet column 14 simultaneously blow out heat exchange airflow, for example, blowing cooling airflow in summer and heating airflow in winter, thereby efficiently adjusting the ambient temperature to be close to the set temperature of the air conditioner 10. When the difference between the ambient temperature and the set temperature of the air conditioner 10 is not greater than (equal to or less than) the temperature threshold, only the first air outlet column 12 blows out heat exchange airflow, while the second air outlet column 14 directly blows out ambient temperature airflow that is drawn in from the air inlet of the air conditioner 10 without being heat exchanged by the heat exchanger (that is, ambient temperature airflow is airflow with a temperature equal to or close to the ambient temperature). At this time, the heat exchange airflow provided by the first air outlet column 12 is used to further adjust the ambient temperature. The evaporator of the first air outlet column 12 provides cooling or heating to the environment so that the ambient temperature is closer to the set temperature of the air conditioner 10. Meanwhile, the ambient warm airflow provided by the second air outlet column 14 is used to stir the ambient air to increase the air circulation in the environment. On the one hand, it helps to distribute the cooling or heating carried by the heat exchange airflow to all places. On the other hand, it can also form an ambient wind with a suitable temperature, improve the user's comfort in the environment, and continue to reduce and control the ambient temperature without the user being directly blown by the heat exchange airflow.

[0042] Because the air conditioner 10 continuously blows heat exchange air during this period, even when the ambient temperature is very close to the set temperature of the air conditioner 10 (which can usually be understood as the ambient temperature being equal to the set temperature; for example, when the difference between the two is less than 0.5℃, it can be rounded to mean that the ambient temperature is equal to the set temperature, or that the ambient temperature is very close to the set temperature), the first air outlet column 12 continues to blow heat exchange air to continue to provide cooling or heating to the environment, and the second air outlet column 14 simultaneously blows ambient temperature air. The compressor of the air conditioner 10 does not need to frequently start and stop or continuously change frequency, but only needs to work continuously and provide a certain amount of cooling or heating.

[0043] Figure 3 This is a flowchart illustrating a control method for an air conditioner 10 according to another embodiment of the present invention.

[0044] refer to Figure 3 As shown, in some optional embodiments, the control method of the air conditioner 10 includes, in addition to the control of the outlet airflow temperature described above, the control of the outlet airflow direction. Specifically:

[0045] Step S302: Control the air conditioner 10 to start.

[0046] Step S304: Control the first air outlet column 12 to outlet air in a preset direction;

[0047] Step S306: Control the second air outlet column 14 to swing horizontally back and forth to output air.

[0048] It is understood that the above-mentioned steps for controlling the air outlet direction are executed after the air conditioner 10 is started, and can be executed simultaneously with the steps for controlling the air outlet temperature. That is to say, steps S304 to S306 can be executed before or after steps S204 to S210, or simultaneously with steps S204 to S210. In other words, the air conditioner 10 can control the air outlet direction before or after controlling the air outlet temperature, or it can control both the air outlet temperature and the air outlet direction simultaneously.

[0049] There is no specific order of execution for steps S304 to S306. That is to say, after the air conditioner 10 is started, the air outlet direction of the first air outlet column 12 and the second air outlet column 14 can be adjusted sequentially, or the air outlet direction of the first air outlet column 12 can be adjusted while the second air outlet column 14 swings to emit air.

[0050] In the above embodiment, the first air outlet column 12 blows heat exchange air in a predetermined direction, while the second air outlet column 14 swings laterally to blow air, switching between blowing heat exchange air or ambient warm air according to the ambient temperature. Specifically, when the difference between the ambient temperature and the set temperature of the air conditioner 10 is not greater than a preset temperature difference threshold, or when the ambient temperature is very close to the set temperature of the air conditioner 10, since the heat exchange air blown by the first air outlet column 12 is blown in a predetermined direction, and the second air outlet column 14 blows ambient warm air while swinging, the air conditioner 10 can effectively prevent users in the environment from being directly blown by the heat exchange air by adjusting the preset direction. At the same time, since the ambient air is continuously stirred by the ambient warm air blown by the swinging second air outlet column 14, the users will not feel stuffy.

[0051] Even when the ambient temperature is very close to the set temperature of the air conditioner 10, although the first air outlet column 12 still blows heat exchange airflow that creates a temperature difference with the ambient temperature, the user will not actively turn off the air conditioner 10 or adjust its set temperature because the airflow temperature felt by the user is mainly the ambient temperature airflow blown by the second air outlet column 14. The control method of the air conditioner 10 in the above embodiment not only eliminates the need for active control of frequent compressor start-stop or continuous frequency conversion, but also further avoids compressor start-stop or frequency conversion caused by user-issued control commands.

[0052] In order to further improve the control effect of air conditioner 10 on ambient temperature, in some optional embodiments, air conditioner 10 determines the preset direction in the following manner: acquiring the environmental characteristics of the operating environment of air conditioner 10; determining the preset direction according to the environmental characteristics; adjusting the air outlet direction of the first air outlet column 12 to face the preset direction, so that the heat exchange airflow blown by the first air outlet column 12 forms an air curtain in the preset direction and separates the temperature regulation space within the operating environment of air conditioner 10.

[0053] The environmental characteristics of the operating environment of the air conditioner 10 can include the environmental layout within the operating environment. For a household air conditioner 10, this usually refers to the room layout, that is, the location of the room walls and the location of the air conditioner 10 itself within the room. Environmental characteristics can also include the location of doors and windows, the location of heat sources (or cold sources), and the placement of furniture, etc.

[0054] Environmental features can be obtained in the following ways: A camera is installed on the air conditioner 10 to capture images of the surrounding environment. By identifying features such as walls, doors, windows, and furniture within the images, specific environmental features can be obtained. If the location of a heat source (or cold source) needs to be obtained, an infrared sensor can be installed. Alternatively, the user can input information on the air conditioner 10's control panel or other external devices (such as a mobile app) to allow the air conditioner 10 to acquire environmental features of the surrounding environment (e.g., which side of the room has doors or windows). It is understood that the specific methods for obtaining environmental features are not limited to the above, and will not be elaborated further here.

[0055] Based on the acquired environmental characteristics, the air conditioner 10 can identify the user's main activity space as the temperature control space, and make the first air outlet column 12 of the air conditioner 10 blow air in a preset direction to form an air curtain, using the air curtain to separate the temperature control space from other specific areas, while the second air outlet column 14 swings to blow air into the temperature control space.

[0056] Because doors and windows are significantly less effective at insulation than walls, even without opening them, heat exchange can easily occur at these points when there is a large temperature difference between indoors and outdoors. This leads to the loss of cool or warm air from indoors and the inflow of cool or warm air from outdoors. This is especially true in the hot summer, when windows or balconies exposed to direct sunlight are particularly susceptible to heat intrusion. In winter, drafts from windows or balconies can also negatively impact user comfort.

[0057] Users are accustomed to placing air conditioners 10, especially floor-standing air conditioners 10, near the corners of rooms to avoid affecting the placement of sofas and other furniture, and to ensure that the airflow radiates over a large area of ​​the room. When the air conditioner 10 in the above embodiment is placed near doors, windows, or balconies, by adjusting its preset direction, the air conditioner 10 can effectively isolate these areas from the temperature-controlled space, thereby preventing heat or cold from these areas from affecting the ambient temperature within the temperature-controlled space.

[0058] Specifically, the steps for determining the preset direction based on environmental characteristics include: identifying the high-impact area with the largest temperature difference from the set temperature of the air conditioner 10, and the side wall position in the operating environment that is far from the air conditioner 10 and adjacent to the high-impact area; setting the direction of the air outlet of the first air outlet column 12 facing the side wall as the preset direction; or setting the direction of the air outlet of the first air outlet column 12 towards the area between the side wall and the high-impact area as the preset direction.

[0059] Figure 4 This is a schematic diagram of the operating environment of an air conditioner 10 according to an embodiment of the present invention.

[0060] Figure 4 Arrows indicate the airflow direction of the first air outlet column 12 and the second air outlet column 14. The first air outlet column 12 is close to the high-influence area B and forms an air curtain separating the high-influence area B from the temperature control space A with the blown heat exchange airflow, while the second air outlet column 14 swings back and forth towards the temperature control space A to release air.

[0061] refer to Figure 4 As shown, since areas such as doors, windows, and balconies tend to exchange heat more with the outdoor environment, high-impact area B usually corresponds to the area where the doors, windows, or balconies are located. After confirming the location of high-impact area B, confirm the location of the side wall that is far away from the air conditioner 10 and adjacent to high-impact area B. This is usually the opposite side wall of the side wall near the air conditioner 10.

[0062] The preset direction of the first air outlet column 12 can be as follows: Figure 4 The location shown is set directly opposite this side wall, or towards this side wall and between the high-impact area B such as doors, windows, and balconies, so that the air curtain blown by the first air outlet column 12 in this fixed direction can separate the high-impact area B from the temperature-controlled space A, preventing the heat or cold energy entering the room from the high-impact area B from affecting the temperature-controlled space A which is being cooled or heated.

[0063] Furthermore, since the first air outlet column 12 continuously blows heat exchange airflow, for example, in summer, the first air outlet column 12 blows cooling airflow, and the heat from the outside environment entering the room from the high-impact area B is neutralized by the cooling capacity carried by the air curtain formed by the first air outlet column 12. As long as the wind speed and cooling capacity carried by the first air outlet column 12 are properly adjusted, the heat entering the room from the high-impact area B will not affect the temperature-controlled space A on the other side of the air curtain at all. In winter, the first air outlet column 12 blows heating airflow, which can neutralize the cooling capacity entering the room from the high-impact area B.

[0064] Specifically, in some optional embodiments, the airflow direction of the second air outlet column 14 is set to not intersect with the preset direction of the first air outlet column 12. That is, during the swinging process of the second air outlet column 14 towards the first air outlet column 12, the farthest position it can swing to is a position where the airflow direction is parallel to the preset direction of the first air outlet column 12. In this way, the airflow from the second air outlet column 14 during its reciprocating swing will not interfere with the air curtain formed by the first air outlet column 12.

[0065] It is understood that in the above embodiments, the definitions of the first air outlet column 12 and the second air outlet column 14 are based on the environmental characteristics of the operating environment of the air conditioner 10, rather than the relative positional relationship of the first air outlet column 12 and the second air outlet column 14 on the air conditioner 10. That is, the first air outlet column 12 is relatively closer to the high-impact area B, while the second air outlet column 14 is directed towards the temperature-controlled space A during the swinging air outlet process (it does not need to pass through the air curtain formed by the first air outlet column 12). Therefore, depending on the specific location of the air conditioner 10 in the environment and the different environmental characteristics of the operating environment of the air conditioner 10, the first air outlet column 12 and the second air outlet column 14 of the same air conditioner 10 may also change.

[0066] Figure 5 This is a schematic flowchart of a control method for an air conditioner 10 according to another embodiment of the present invention.

[0067] To make the air conditioner 10 more intelligent and to turn it on in advance to lower the ambient temperature and prevent the user from being directly blasted by the heat exchange airflow, in some optional implementations, the air conditioner 10 is started based on the following control method:

[0068] Step S502: Obtain the positioning distance between the user and the air conditioner 10 and the preset distance threshold;

[0069] Step S504: Determine whether the positioning distance is less than the distance threshold;

[0070] If so, proceed to step S506 to start the air conditioner 10.

[0071] For commuters who leave early and return late, the air conditioner 10 needs to be turned off while away from home to save electricity. However, if the air conditioner 10 is turned on after arriving home, the ambient temperature takes some time to adjust to the ideal temperature. During this time, the user has to endure uncomfortably low ambient temperature and direct airflow. To improve user comfort at home, the control method of the air conditioner 10 also includes obtaining the location distance between the user and the air conditioner 10. By comparing this distance with a preset distance threshold, it can be determined whether the user is on their way home. For example, for a user whose workplace is 10 kilometers away from home, the distance threshold is preset to 5 kilometers. When the user enters this range from outside 5 kilometers, it usually means that the user is on their way home. At this time, the air conditioner 10 is turned on, and it can adjust the indoor ambient temperature in advance. When the user arrives home, the air conditioner 10 has usually already adjusted the ambient temperature to a level where the difference between the ambient temperature and the set temperature of the air conditioner 10 is less than the preset temperature difference threshold. At this time, the airflow from the second air outlet column 14 is also ambient temperature airflow, so the user will not be directly blasted by the heat exchange airflow.

[0072] The distance threshold can be set by the user based on the distance between their workplace or frequently visited location and their home, with a relatively flexible parameter range. The air conditioner's preset temperature difference threshold can also be set by the user; the default temperature difference threshold parameter can be set to 3℃.

[0073] The location distance between the user and the air conditioner 10 can be obtained through a device that can be connected to the air conditioner 10. For example, if the user binds the air conditioner 10 to a mobile app, the location distance between the user and the air conditioner 10 can be obtained using the phone's location function. Alternatively, devices such as smart bracelets can also be connected to the air conditioner 10, and this is not a limitation.

[0074] When the heat exchanger of the second air outlet column 14 stops, that is, when the second air outlet column 14 switches from blowing heat exchange airflow to blowing ambient temperature airflow, the air conditioner 10's demand for cooling or heating also decreases accordingly. Therefore, in some optional embodiments, when the difference between the ambient temperature and the set temperature of the air conditioner 10 is greater than a temperature difference threshold, the control method of the air conditioner 10 further includes: when the difference between the ambient temperature and the set temperature is equal to the temperature difference threshold, detecting the compressor frequency of the air conditioner 10 and obtaining a preset frequency threshold; determining whether the compressor frequency is greater than the frequency threshold; if so, controlling the compressor to reduce its frequency to the frequency threshold.

[0075] The preset frequency threshold is equal to the temperature difference threshold between the ambient temperature and the set temperature of the air conditioner 10, and corresponds only to the optimal compressor frequency when the heat exchanger of the first air outlet column 12 starts. That is to say, if the ambient temperature reaches the above conditions, and the compressor frequency is higher than the frequency threshold at the same time as the heat exchanger of the second air outlet column 14 stops, then the compressor frequency will be reduced to the frequency threshold so that the compressor of the air conditioner 10 does not generate excess cooling or heating.

[0076] Based on this, in some optional embodiments, the frequency of the compressor can be further reduced as the difference between the ambient temperature and the set temperature of the air conditioner 10 decreases.

[0077] In some alternative implementations, the operating power of the air conditioner 10 can be adjusted more finely when the ambient temperature is stable, thereby better maintaining the ambient temperature near the set temperature of the air conditioner 10. Specifically, when the ambient temperature is very close to the set temperature of the air conditioner 10, the compressor frequency is adjusted according to the difference between the average temperature of the high-influence area and the set temperature; that is, the greater the difference between the average temperature of the high-influence area and the set temperature, the higher the compressor frequency. Through the above embodiments, the air curtain formed by the first air outlet column 12 can better offset the heat or cold in the high-influence area.

[0078] Figure 6 This is a schematic block diagram of an air conditioner 10 according to an embodiment of the present invention.
