Description

Air conditioners and their control methods Technical Field

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

[0002] When existing air conditioners are in heating mode, hot air rises automatically because it is less dense, while cold air sinks because it is denser. This results in automatic stratification of hot and cold air. However, existing air conditioners use a fixed airflow pattern and cannot compensate for the actual conditions of the room, leading to poor room temperature uniformity, especially a large temperature difference between the top and bottom of the room, which affects the user's actual experience. Summary of the Invention

[0003] In view of the above problems, the present invention is proposed to provide an air conditioner and its control method that overcome or at least partially solve the above problems, aiming to solve the problem of large temperature difference between the upper and lower parts of the room when the air conditioner is in heating mode, so as to improve the user experience.

[0013] In response to the temperature difference being greater than or equal to a preset difference, and the air outlet angles of the two air outlets not being the maximum downward angle, the air outlet angles of the two air outlets are controlled to be adjusted downward by a preset angle, and the operation is carried out for a first preset time.

[0014] Determine whether the current temperature difference is less than a preset difference;

[0015] If so, maintain the current air outlet angle;

[0016] If not, in response to the fact that the air outlet angles of the two air outlets are not the maximum downward angle, return to the step of adjusting the air outlet angles of the two air outlets downward by a preset angle and running for a first preset time until the air outlet angle is the maximum downward angle or the temperature difference is less than the preset difference, and maintain the current air outlet angle.

[0017] Optionally, the step of adjusting the air outlet angle and air volume of the two air outlets according to the temperature difference in a predetermined priority order further includes:

[0018] In response to the air outlet angle being the maximum downward angle and the temperature difference being greater than or equal to a preset difference, the position of the vertical blade assembly is obtained to obtain a first position;

[0019] In response to the first position not being in the center position, the vertical swing blade assembly is controlled to rotate from the first position to the center position to increase the air volume of the air outlet, and then run for a second preset time.

[0020] Optionally, the step of adjusting the air outlet angle and air volume of the two air outlets according to the temperature difference in a predetermined priority order further includes:

[0021] In response to the vertical blade assembly being in the center position and the current temperature difference being greater than or equal to a preset difference, the upper air outlet is closed.

[0022] Optionally, the control method further includes:

[0023] In response to the third preset time of the air conditioner's heating operation, the step of obtaining the temperature difference between the indoor temperature at the first height and the indoor temperature at the second height is performed.

[0024] Optionally, the control method further includes:

[0036] In the air conditioner control method of the present invention, the downward air outlet angle is preferentially adjusted according to the vertical temperature difference in the indoor environment. On the one hand, this can reduce the vertical temperature difference in the indoor environment, improve the uniformity of temperature throughout the room, and thus enhance the user experience.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] Figure 1 is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention. In conjunction with Figures 2-7, the present invention provides an air conditioner control method. The air conditioner includes two air outlets arranged vertically. The two air outlets are an upper air outlet and a lower air outlet; the upper air outlet is located above the lower air outlet.

[0050] As shown in Figure 1, the air conditioner is operating in heating mode, and the control method includes the following steps:

[0051] Step S11: Obtain the temperature difference between the indoor temperature at the first and second altitudes.

[0052] Step S12: Adjust the air outlet angle and / or air volume of the two air outlets according to the temperature difference value in a predetermined priority order, wherein adjusting the downward air outlet angle has a higher priority than adjusting the air volume.

[0053] Specifically, in step S11, the "temperature difference between the first and second heights of the room" represents the temperature difference between the upper and lower parts of the room. This temperature difference indicates that the greater the temperature difference between the upper and lower parts of the room, the more uneven the indoor environment. The purpose of step S12 is to reduce this temperature difference. For example, when the temperature difference between the upper and lower parts of the room is large, the downward air outlet angle is adjusted first to increase the temperature of the lower part of the room, thereby reducing the temperature difference between the upper and lower parts of the room. Based on the actual adjustment effect, it can be determined whether it is necessary to continue adjusting the airflow of the two air outlets. Adjusting the airflow includes adjusting the size of the two air outlets. The size of the air outlet refers to the ventilation area of ​​the air outlet.

[0054] In this embodiment, the air outlet angle is adjusted preferentially based on the vertical temperature difference within the indoor environment. On one hand, this reduces the vertical temperature difference, improving the uniformity of temperature throughout the room and thus enhancing the user experience. On the other hand, compared to prioritizing airflow adjustment, prioritizing airflow angle adjustment effectively avoids situations where excessive airflow leads to dry indoor air, causing discomfort such as dry skin and itchy throat, and increased indoor noise. Furthermore, the control method of this invention has the advantages of simple and easy-to-execute control procedures.

[0055] In some optional embodiments of the present invention, the control method further includes: in response to the start of the air conditioner, obtaining the operating mode of the air conditioner; in response to the operating mode of the air conditioner being a heating mode, controlling the air conditioner to operate in heating mode.

[0056] In some optional embodiments of the present invention, the preset difference is 3 to 7°C (e.g., 3°C, 4°C, 4.5°C, 4.8°C, 5°C, 5.5°C, 5.8°C, 6°C, 6.5°C, or 7°C). Preferably, the preset difference is 5°C.

[0057] In some optional embodiments of the present invention, obtaining the temperature difference between an indoor space at a first height and an indoor space at a second height includes the following steps: obtaining the temperature at the first height to obtain a first temperature; simultaneously obtaining the temperature at the second height to obtain a second temperature; and calculating the difference between the first temperature and the second temperature.

[0058] Specifically, the first height is greater than the second height. The first temperature represents the upper temperature of the indoor environment; the second temperature represents the lower temperature of the indoor environment.

[0059] As shown in Figures 5-6, in some optional embodiments of the present invention, each air outlet is provided with an air guiding device. Each air guiding device includes a vertical oscillating blade assembly 10 and a horizontal oscillating blade assembly 20.

[0060] As shown in Figure 5, the vertical oscillating blade assembly 10 extends vertically along the air outlet. The vertical oscillating blade assembly 10 is configured to rotate around a vertical axis of the air conditioner to adjust the lateral air outlet direction and air volume.

[0061] As shown in Figure 6, the horizontal louver group 20 is disposed inside the corresponding air outlet. The multiple horizontal louvers of the horizontal louver group are arranged vertically, and each horizontal louver is configured to swing up and down along the vertical direction of the air conditioner to adjust the vertical air outlet direction.

[0062] The vertical sway blade assembly 10 and the horizontal sway blade assembly 20 work together to guide the airflow, allowing the airflow to blow in any direction and achieve point-to-point air delivery.

[0063] In this embodiment, the air guiding device corresponding to each air outlet is a separate structure, and each air guiding device can be controlled independently. The horizontal oscillating blade group 20 corresponding to each air outlet is used to control the up and down airflow direction of the air outlet, and the vertical oscillating blade group 10 corresponding to each air outlet can be used to control the left and right airflow direction of the air outlet.

[0064] As shown in Figure 2, in some optional embodiments of the present invention, adjusting the air outlet angle and / or air volume of the two air outlets according to the temperature difference in a predetermined priority order includes the following steps:

[0065] Step S21: In response to the temperature difference being greater than or equal to a preset difference, and the air outlet angles of the two air outlets not being the maximum downward angle, the air outlet angles of the two air outlets are controlled to be adjusted downward by a preset angle, and the process is run for a first preset time.

[0066] Step S22: Determine whether the current temperature difference is less than a preset difference.

[0067] Step S23: If yes, maintain the current air outlet angle; if no, in response to the air outlet angle of the two air outlets not being the maximum downward angle, return to the step of controlling the air outlet angle of both air outlets to adjust downward by a preset angle and running for a first preset time until the air outlet angle is the maximum downward angle or the temperature difference is less than the preset difference, and maintain the current air outlet angle.

[0068] Specifically, to prevent excessive temperature differences between the upper and lower parts of the room, when the temperature difference is greater than or equal to a preset difference, it is determined whether the air outlet angles of the two air outlets of the air conditioner are at their maximum downward angle. If neither air outlet angle is at its maximum downward angle, the air outlet angles of both air outlets are adjusted downward by a preset angle (denoted as Δα), and this is carried out for a first preset time. Then, the current temperature difference is obtained again, and it is determined whether the current temperature difference is less than the preset difference: if the current temperature difference is less than the preset difference, it means that adjusting the preset angle Δα downwards of both air outlets has effectively solved the problem of large temperature differences between the upper and lower parts of the room, and the current air outlet angles are maintained; if the current temperature difference is still greater than or equal to the preset difference, it means that adjusting the preset angle Δα downwards of both air outlets has not solved the problem of large temperature differences between the upper and lower parts of the room, and step S21 is executed again until the air outlet angles of both air outlets are at their maximum downward angles, and the current air outlet angles of both air outlets are maintained; or, the current air outlet angles of both air outlets are maintained until the current temperature difference is less than the preset difference.

[0069] In summary, in this embodiment, during the heating operation of the air conditioner, when there is a large temperature difference between the upper and lower parts of the room, a method of gradually increasing the downward air outlet angle is preferentially adopted to reduce the temperature difference between the upper and lower parts of the indoor environment. This control method is simple and easy to operate, and can improve the uniformity of the temperature throughout the room, thereby improving the user experience. During the adjustment of the air outlet angle, when the temperature difference is less than the preset difference, it indicates that the temperature difference between the upper and lower parts of the room is small, and the current air outlet angle can be maintained; or, when the air outlet angles of both air outlets are adjusted to the maximum downward angle, the current air outlet angle is also maintained. In addition, compared with the method of directly adjusting the air outlet angles of both air outlets to the maximum downward angle, the method of gradually increasing the downward air outlet angle adopted by this invention can further prevent excessive adjustment of the temperature difference between the upper and lower parts of the room, that is, it can further avoid the occurrence of the lower part of the room being warmer than the upper part.

[0070] As shown in Figure 3, in some optional embodiments of the present invention, the step of adjusting the air outlet angle and air volume of the two air outlets according to the temperature difference value in a predetermined priority order further includes the following steps:

[0071] Step S31: In response to the air outlet angle being the maximum downward angle and the temperature difference being greater than or equal to a preset difference, the position of the vertical blade assembly is obtained to obtain the first position.

[0072] Step S32: In response to the first position not being in the center position, control the vertical swing blade assembly to rotate from the first position to the center position to increase the air volume of the air outlet, and run for a second preset time.

[0073] In this embodiment, when the air outlet angles of the two air outlets are at their maximum downward angles, if the temperature difference is still greater than or equal to a preset difference, then while maintaining the maximum downward angles, the two vertical sway blade groups 10 are adjusted to a centered position to increase the airflow from the air outlets, causing the lower part of the indoor environment to heat up rapidly, thereby reducing the temperature difference. Specifically, when the vertical sway blade groups are in the centered position, the air outlet opening is at its maximum, meaning the air outlet ventilation area is at its maximum. In other words, by adjusting the two vertical sway blade groups 10 to a centered position, the air outlet ventilation area of ​​the two air outlets is adjusted to its maximum value.

[0074] Furthermore, the control method further includes the following step: maintaining the first position in response to the first position being in the center position.

[0075] In some optional embodiments of the present invention, the step of adjusting the air outlet angle and air volume of the two air outlets according to the temperature difference in a predetermined priority order further includes the following steps: in response to the vertical blade group being in the center position and the current temperature difference being greater than or equal to a preset difference, closing the upper air outlet.

[0076] Specifically, through the above steps, the air volume of the lower air outlet can be made greater than that of the upper air outlet.

[0077] In this embodiment, after the step of "controlling the vertical sway blade group to rotate from the first position to the central position and running for a second preset time", it is determined whether the current temperature difference is less than the preset difference. If the current temperature difference is still greater than or equal to the preset difference, it indicates that the above-mentioned measures of "adjusting the downward air outlet angle and increasing the air outlet volume" (both horizontal sway blade groups are rotated to the maximum downward angle and both vertical sway blade groups are in the central position) cannot effectively solve the problem of large temperature difference between the upper and lower parts of the indoor environment. At this time, the air outlet at the upper part is closed, and only the air outlet at the lower part is opened, so that the air volume at the upper part of the room is very small and the air volume at the lower part is very large, and the air volume is concentrated downward, so as to further avoid direct air supply to the upper environment, thereby effectively solving the problem of large temperature difference between the upper and lower parts of the indoor environment.

[0078] As shown in Figure 4, in some optional embodiments of the present invention, the control method further includes the following steps:

[0079] Step S41: In response to the closure of the upper air outlet, after a fourth preset time, the current temperature difference value is obtained.

[0080] Step S42: Determine whether the temperature difference is less than the preset difference.

[0081] Step S43: If so, open the air outlet located at the top.

[0082] In some optional embodiments of the present invention, the control method further includes the following steps: in response to a third preset time of heating operation of the air conditioner, performing the step of obtaining the temperature difference between the indoor temperature at a first height and the indoor temperature at a second height.

[0083] Specifically, since the indoor temperature is relatively uniform when the air conditioner first starts running, it is not necessary to obtain the temperature difference value at this time. Therefore, the temperature difference value is only obtained after the third preset heating time has elapsed.

[0084] In another alternative embodiment of the invention, the control method further includes the step of: in response to the start of the air conditioner, starting to acquire the temperature difference value.

[0085] In some optional embodiments of the present invention, obtaining the temperature difference between an indoor space at a first height and a second height includes the following steps:

[0086] Step S51: Obtain the temperature of multiple temperature measuring points at the first height in the room and calculate the first average temperature; and obtain the temperature of multiple temperature measuring points at the second height in the room and calculate the second average temperature.

[0087] Step S52: Calculate the temperature difference between the first average temperature and the second average temperature.

[0088] In this embodiment, a first average temperature (i.e., the first temperature) is obtained based on the temperatures of multiple temperature measuring points at a first altitude. This first average temperature reflects the overall temperature state of the indoor environment at the first altitude. Similarly, a second average temperature (i.e., the second temperature) is obtained based on the temperatures of multiple temperature measuring points at a second altitude. This second average temperature reflects the overall temperature state of the indoor environment at the second altitude. Therefore, this embodiment can obtain the true temperature difference between the first and second altitudes in the indoor environment. In other words, it reflects the true temperature difference between the upper and lower altitudes of the indoor environment. Based on this true temperature difference, misjudgments can be avoided, making it more conducive to precise control of the air conditioner.

[0089] Preferably, the second height is 0.2m above the indoor ground, and the first height is 2m above the indoor ground, that is, the difference between the first height and the second height is 1.8m.

[0090] In some optional embodiments of the present invention, there are three temperature measuring points both at the first and second indoor heights.

[0091] As shown in Figure 7, the three temperature measuring points at the first altitude indoors are A1, B1, and C1. The three temperature measuring points at the second altitude indoors are A2, B2, and C2.

[0092] Specifically, there are a total of 6 temperature measurement points indoors, namely:

[0093] Temperature measurement point A1 is located on the left side of the air conditioner and at the first height.

[0094] Temperature measuring point B1 is located on the front side of the air conditioner and at the first height.

[0095] Temperature measuring point C1 is located to the right of the air conditioner and at the first height.

[0096] Temperature measurement point A2 is located on the left side of the air conditioner and at the second height.

[0097] Temperature measurement point B2 is located on the front side of the air conditioner and at the second height.

[0098] Temperature measurement point C2 is located to the right of the air conditioner and at the second height.

[0099] For example, the second height is 0.2m from the indoor ground, and the first height is 2m from the indoor ground. That is to say, the difference between the first height and the second height is 1.8m.

[0100] In some alternative embodiments of the present invention, obtaining the temperature difference between an indoor space at a first height and an indoor space at a second height includes the following steps: obtaining the temperature of a temperature measuring point at the first height to obtain a first temperature; obtaining the temperature of a temperature measuring point at the second height to obtain a second temperature; and calculating the temperature difference between the first temperature and the second temperature.

[0101] In some alternative embodiments of the present invention, obtaining the temperature difference between the indoor temperature at a first height and the indoor temperature at a second height includes the following steps: obtaining the temperature of four temperature measuring points at the first height to obtain a first average temperature; obtaining the temperature of four temperature measuring points at the second height to obtain a second average temperature; and calculating the temperature difference between the first average temperature and the second average temperature.

[0102] In some optional embodiments of the present invention, the temperature difference between the indoor temperature at the first altitude and the temperature at the second altitude is acquired every 3 minutes.

[0103] In some optional embodiments of the present invention, an infrared temperature sensor 30 is provided on the front side of the air conditioner to obtain the temperature of multiple temperature measuring points in the room.

[0104] Preferably, the infrared temperature sensor 30 is installed on the upper part of the air conditioner housing and is located above the air outlet.

[0105] In existing technologies, air conditioning parameter acquisition is generally achieved through automatic control using ambient temperature sensors at the air inlet and sensors on the inner coils of the indoor heat exchanger. However, the ambient temperature sensors, which collect the air temperature parameters entering the air conditioner, are limited by the airflow area and can only reflect the air temperature near the air conditioner. They cannot accurately reflect the overall air temperature distribution throughout the room. Even with temperature compensation in the control scheme, it remains a fixed mode, and its accuracy is difficult to achieve due to factors such as room shape and area.

[0106] In this embodiment, by setting an infrared temperature sensor 30 on the front of the air outlet, the temperature of different temperature measurement points throughout the house is scanned, and directional air is delivered, which can ensure the uniformity of the temperature throughout the house and improve the user's air conditioning experience.

[0107] In some optional embodiments of the present invention, adjusting the air outlet angle and air volume of the two air outlets according to the temperature difference value in a predetermined priority order includes the following steps:

[0108] Step S61: In response to the temperature difference being greater than or equal to a preset difference, and the air outlet angles of the two air outlets not being the maximum downward angle, the air outlet angles of the two air outlets are adjusted to the maximum downward angle, and the process is run for a first preset time.

[0109] Step S62: Determine whether the current temperature difference is greater than or equal to a preset difference.

[0110] Step S63: If yes, in response to the fact that the vertical sway blades of the two air outlets are not in the centered position, control the vertical sway blades of the two air outlets to rotate to the centered position to increase the air volume of the air outlets; if no, maintain the current air outlet angle.

[0111] Figure 5 is a schematic diagram of the structure of an air conditioner according to an embodiment of the present invention. Referring to Figure 6, the present invention also provides an air conditioner including a control device. The control device includes a memory and a processor. The memory stores a control program, which, when executed by the processor, is used to implement the control method of the air conditioner as described in any of the above embodiments.

[0112] In this embodiment, the air conditioner can prioritize adjusting the air outlet angle according to the temperature difference between the upper and lower parts of the indoor environment, thereby reducing the temperature difference between the upper and lower parts of the indoor environment, improving the uniformity of the temperature throughout the room, and thus enhancing the user experience.

[0113] Furthermore, the air conditioner is a cabinet-type air conditioner, that is, a floor-standing cabinet unit.

[0114] In some alternative embodiments of the invention, the air conditioner includes a housing. Two vertically arranged air outlets are provided on the front side of the housing.

[0115] In some optional embodiments of the present invention, each of the air outlets is provided with an air guiding device.

[0116] Each of the aforementioned air guide devices includes a vertical oscillating blade assembly 10 and a horizontal oscillating blade assembly 20.

[0117] As shown in Figure 5, the vertical oscillating blade assembly 10 extends vertically along the air outlet. The vertical oscillating blade assembly 10 is configured to rotate around a vertical axis of the air conditioner to adjust the lateral air outlet direction and air volume.

[0118] As shown in Figure 6, the horizontal louver group 20 is disposed inside the corresponding air outlet. The multiple horizontal louvers of the horizontal louver group are arranged vertically, and each horizontal louver is configured to swing up and down along the vertical direction of the air conditioner to adjust the vertical air outlet direction.

[0119] The vertical sway blade assembly 10 and the horizontal sway blade assembly 20 work together to guide the airflow, allowing the airflow to blow in any direction and achieve point-to-point air delivery.

[0120] In this embodiment, the air guiding device corresponding to each air outlet is a separate structure, and each air guiding device can be controlled independently. The horizontal oscillating blade group 20 corresponding to each air outlet is used to control the up and down airflow direction of the air outlet, and the vertical oscillating blade group 10 corresponding to each air outlet can be used to control the left and right airflow direction of the air outlet.

[0121] In some optional embodiments of the present invention, an infrared temperature sensor 30 is provided on the front side of the air conditioner to obtain the temperature of multiple temperature measuring points in the room.

[0122] Preferably, the infrared temperature sensor 30 is installed on the upper part of the air conditioner housing and is located above the air outlet.

[0123] In some alternative embodiments of the invention, the infrared temperature sensor 30 is mounted on the lower part of the front side of the air conditioner housing.

[0124] In some alternative embodiments of the invention, the infrared temperature sensor 30 is mounted at the center of the front side of the air conditioner housing.

[0125] In existing technologies, air conditioning parameter acquisition is generally achieved through automatic control using ambient temperature sensors at the air inlet and sensors on the inner coils of the indoor heat exchanger. The ambient temperature sensors, which collect the air temperature parameters entering the air conditioner, are limited by the airflow area and can only reflect the air temperature near the air conditioner, making it difficult to assess the overall room temperature distribution. Even with temperature compensation in the control scheme, it remains a fixed mode, and its accuracy is limited by factors such as room shape and area. In this embodiment, however, by placing an infrared temperature sensor 30 on the front of the air outlet, which scans the temperature at different measurement points throughout the room and directs airflow in a directional manner, uniform temperature throughout the room can be ensured, improving the user's air conditioning experience.

[0126] When the remote control is set to the whole-house uniform temperature mode: the vertical oscillating blade assembly 10 and the horizontal oscillating blade assembly 20 can be directed to enhance the airflow to areas with insufficient temperature, ensuring the uniformity of temperature throughout the house.

[0127] 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.
