Abstract
Description
Technical Field
[0001] This invention relates to the field of household appliance technology, and more particularly to a method for calculating a target temperature, an air conditioner, and a computer storage medium. Background Technology
[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.
[0003] When an air conditioner is running, it needs to be precisely controlled based on the indoor temperature and the target temperature sent to it by the control device. The control device, such as a wired controller or remote control, needs to communicate with the air conditioner through a dedicated communication protocol. This dedicated communication protocol is usually a non-public protocol developed internally by the manufacturer, which limits the applicability of the control device. This means that the control device can only send simple control commands to the air conditioner based on its own control logic, such as turning on, turning off, adjusting the fan speed, and controlling the electric auxiliary heating level. However, because there is no data communication connection between the control device and the air conditioner, the air conditioner cannot read the target temperature of the control device, and therefore cannot operate according to the actual target temperature of the control device, making it difficult to adjust the indoor temperature more accurately. Summary of the Invention
[0004] The purpose of this invention is to at least solve the problem of air conditioners being unable to read the target temperature from the control device. This purpose is achieved through the following technical solution:
[0005] A first aspect of the present invention provides a method for calculating a target temperature for an air conditioner. The method for calculating the target temperature includes: acquiring a control signal from a control device after the air conditioner is started; determining a correction value based on the control signal; acquiring a first temperature of the environment where the indoor unit of the air conditioner is located at a first moment, the first moment being the same as the moment when the control signal is received; and determining the target temperature as the sum of the first temperature and the correction value.
[0006] According to the target temperature calculation method of the present invention, when the air conditioner and the control device cannot transmit data information such as the target temperature, the control signal sent by the control device to the air conditioner during the first time period after the air conditioner is started is first obtained. Based on the control signal fed back by the control device and the first temperature of the indoor unit's environment at the time the air conditioner receives the control signal, the target temperature set by the control device is calculated, so that the air conditioner can operate according to the calculated target temperature. This facilitates intelligent and precise control of the operation of each component in the air conditioner during subsequent operation, so as to respond to the user's needs in a timely and effective manner and improve the user experience.

[0025] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0026] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.
[0027] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.
[0028] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.
[0029] like Figure 1 As shown, according to an embodiment of the present invention, a method for calculating a target temperature is proposed. This method is used in air conditioners, specifically, to calculate the target temperature set by the control equipment during the operation of the air conditioner. Specifically, the method for calculating the target temperature includes the following steps:
[0030] Step S101: Obtain the control signal from the control device after the air conditioner is started;
[0031] Step S102: Determine the correction value based on the control signal;
[0032] Step S103: Obtain the first temperature of the environment where the indoor unit of the air conditioner is located at the first moment;
[0033] Step S104: Determine the target temperature as the sum of the first temperature and the correction value.
[0034] Specifically, the first moment is the same as the moment the control signal is received.
[0035] In step S101, when the air conditioner receives a start signal or a cooling mode or heating mode switching signal from the control device, the air conditioner starts operating. During the first period of operation, the air conditioner delivers lower-temperature air to the room to lower the indoor temperature and achieve a cooling function, or delivers higher-temperature air to the room to raise the indoor temperature and achieve a heating function. During this process, the indoor temperature changes as the air conditioner continuously outputs cooling or heating. When the indoor temperature changes, the control logic preset on the control device (such as a wired controller) will adjust the current indoor temperature based on the actual temperature. The control device outputs control signals to the air conditioner based on the relationship between the actual indoor temperature and the set target temperature. For example, in heating mode, if the actual indoor temperature exceeds the target temperature, the control device sends a shutdown signal to the air conditioner once the target temperature is reached. If the actual indoor temperature is much lower than the target temperature, the control device sends a signal to the air conditioner to increase the output power, such as turning on the electric auxiliary heating device. Therefore, when the relationship between the actual indoor temperature and the target temperature is different, the control device sends different control signals to the air conditioner based on its own pre-set control logic to control the operation of the air conditioner based on the target temperature and the actual indoor temperature, so as to meet the user's needs.
[0036] In step S102, it is understood that since the control signal issued by the control device is determined based on its own set control logic, and the control logic of the control device needs to refer to the relationship between the actual value of the indoor temperature and the target temperature, under the premise that the target temperature remains unchanged, different control signals represent different relationships between the actual value of the indoor temperature and the target temperature, such as the relationship between the actual value of the indoor temperature and the target temperature, and the magnitude of the difference between the target temperature and the actual value of the indoor temperature. Therefore, different correction values can be set based on different control signals of the control device.
[0037] Specifically, the correction value is the difference between the indoor temperature and the target temperature at the moment the control device sends a control signal. The correction value corresponding to different control signals can be obtained according to the control logic set by the control device itself. For example, in heating mode, when the indoor temperature exceeds the target temperature by 3°C, the control device sends a temperature-reaching shutdown signal to the air conditioner. Therefore, the correction value corresponding to the temperature-reaching shutdown signal is set to -3°C.
[0038] Understandably, the specific value of the correction is related to the control logic of the control device, and no specific limitation is made here.
[0039] In steps S103 and S104, when the air conditioner receives a control signal, it obtains the first temperature of the environment where the indoor unit of the air conditioner is located at the same time as receiving the control signal. The first temperature can be the temperature at the return air vent of the indoor unit, i.e., the return air temperature of the indoor unit, or it can be the indoor temperature of the space where the indoor unit is located. The target temperature can be calculated by summing the first temperature and the correction coefficient, so that the air conditioner can operate according to the calculated target temperature. This facilitates intelligent and precise control of the operation of each component in the air conditioner in subsequent operation, so as to respond to the user's needs in a timely and effective manner and improve the user experience.
[0040] like Figure 2 As shown, according to an embodiment of the present invention, a method for calculating a target temperature is proposed, the method comprising the following steps:
[0041] Step S201: Obtain the control signal from the control device after the air conditioner is started;
[0042] Step S202: Determine whether a temperature-reaching shutdown signal is received within the first time period after the air conditioner starts. If yes, determine the correction value as the first correction value; otherwise, proceed to step S203.
[0043] Step S203: Determine whether an output conversion signal is received. If yes, determine the correction value as the second correction value; otherwise, proceed to step S204.
[0044] Step S204: Obtain the output status signal at the last moment of the first time period, and determine the correction value as the third correction value;
[0045] Step S205: Obtain the first temperature of the indoor unit of the air conditioner at the same time as receiving the control signal;
[0046] Step S206: Determine the target temperature as the sum of the first temperature and the correction value.
[0047] In this embodiment, step S201 is the same as step S101, and steps S205 to S206 are the same as steps S103 to S104, and will not be described again here.
[0048] In step S202, during the first time period after the air conditioner is started, it is first determined whether a temperature-reaching shutdown signal is received. If a temperature-reaching shutdown signal is received, it means that after the air conditioner is turned on, the indoor temperature has reached the target temperature at the time the temperature-reaching shutdown signal is received. Therefore, the first temperature of the environment where the air conditioner is located at the time of temperature-reaching shutdown is obtained, and the correction value is determined to be the first correction value corresponding to the temperature-reaching shutdown signal. The target temperature can be calculated by calculating the sum of the first temperature and the first correction value.
[0049] In detail, to avoid the air conditioner repeatedly turning on and off in a short period of time, the control equipment will generally issue a temperature-reaching shutdown command only after the indoor temperature reaches and exceeds the target temperature by a certain value.
[0050] For example, in heating mode, if the target temperature set by the control device is T1S' and the indoor temperature is T1', then when T1'-T1S'≥X (X>0, X can be set to 1℃, 2℃, 3℃, 4℃, 5℃, etc.), the control device will issue a temperature-reached shutdown command. The first correction value is set to -X. The first temperature of the environment where the air conditioner is located is T1, and the target temperature T1S=T1-X.
[0051] In cooling mode, if the target temperature set by the control device is T1S' and the indoor temperature is T1', then when T1S'-T1'≥X (X>0, X can be set to 1℃, 2℃, 3℃, 4℃, 5℃, etc.), the control device will issue a temperature-reached shutdown command. The first correction value is set to X, the first temperature of the environment where the air conditioner is located is T1, and the target temperature T1S=T1+X.
[0052] In step S203, if no temperature-reaching shutdown signal is received within the first time period, it indicates that the air conditioner has not yet reached the target indoor temperature after running for the first time period. Therefore, it is determined whether an output conversion signal is received within the first time period. Specifically, the output conversion signal is a control signal issued by the control device based on the difference between the current indoor temperature and the target temperature, which changes the cooling or heating output state of the air conditioner. For example, if the difference between the indoor temperature and the target temperature is large, it indicates that the current cooling or heating output capacity of the air conditioner is far from meeting the actual needs. Therefore, the control device will issue a control signal to increase the output power of the air conditioner to improve the cooling or heating output capacity of the air conditioner. When the indoor temperature has not reached the target temperature, but the difference between the indoor temperature and the target temperature is small, the control device will issue a control signal to reduce the output power of the air conditioner. Under the premise of ensuring that the air conditioner continues to output cooling or heating to basically meet the user's needs, the indoor temperature changes smoothly and energy is saved. Understandably, different output switching signals can determine the different differences between the indoor temperature and the target temperature. Therefore, when no temperature-reaching shutdown signal is received, the corresponding second correction value can be determined based on the output switching signal.
[0053] For example, in heating mode, if the target temperature set by the control device is T1S' and the indoor temperature is T1', then when T1S'-T1'≥Y (Y>0, Y can be set to 1℃, 2℃, 3℃, 4℃, 5℃, etc.), the control device will send an output conversion signal, and the second correction value will be set to Y. At the same time that the control device sends the output conversion signal, the first temperature of the environment where the air conditioner is located is T1, and the target temperature T1S=T1+Y.
[0054] In cooling mode, if the target temperature set by the control device is T1S' and the indoor temperature is T1', then when T1'-T1S' ≥ Y (Y>0, Y can be set to 1℃, 2℃, 3℃, 4℃, 5℃, etc.), the control device will issue a temperature-reached shutdown command. The second correction value is set to -Y. At the same time that the control device issues the output conversion signal, the first temperature of the environment where the air conditioner is located is T1, and the target temperature T1S=T1-Y.
[0055] In step S204, if neither a temperature-reaching shutdown signal nor an output change signal is received during the first time period, it indicates that the air conditioner's cooling or heating output state remains unchanged during the first time period, and the indoor temperature has not reached the target temperature during the first time period. Therefore, the output state signal at the last moment of the first time period is obtained, and the difference between the indoor temperature and the target temperature is determined according to the different output states of the air conditioner. The greater the cooling or heating output efficiency of the air conditioner, the greater the absolute value of the third correction value.
[0056] For example, in heating mode, if the air conditioner's heat output status signal is in a high power state, it means that the air conditioner has not yet reached the target indoor temperature after operating at a high power state for the first time period. Therefore, the third correction value is set to Z1 (Z1 > 0), and the first temperature T1 of the environment where the air conditioner is located at the last moment of the first time period is obtained. Then the target temperature T1S = T1 + Z1. If the air conditioner's heat output status signal is in a low power state, it means that the air conditioner has not yet reached the target indoor temperature after operating at a low power state for the first time period. Therefore, the third correction value is set to Z2 (Z2 > 0), and the first temperature T1 of the environment where the air conditioner is located at the last moment of the first time period is obtained. Then the target temperature T1S = T1 + Z2. Where Z1 ≥ Z2.
[0057] In cooling mode, if the air conditioner's cooling output status signal is in a high power state, it means that the air conditioner has not yet reached the target indoor temperature after operating at a high power state for the first time period. Therefore, the third correction value is set to -Z3 (Z3 > 0), and the first temperature T1 of the environment where the air conditioner is located at the last moment of the first time period is obtained. Then the target temperature T1S = T1 - Z3. If the air conditioner's cooling output status signal is in a low power state, it means that the air conditioner has not yet reached the target indoor temperature after operating at a low power state for the first time period. Therefore, the third correction value is set to -Z4 (Z4 > 0), and the first temperature T1 of the environment where the air conditioner is located at the last moment of the first time period is obtained. Then the target temperature T1S = T1 - Z4. Where Z3 ≥ Z4.
[0058] In this embodiment, the value range of the first time period t is 0.1 hours to 24 hours. The first time period is related to the output capacity of the air conditioner and the volume of the building space where the air conditioner is located. The first time period t can be set to 0.1 hours, 0.2 hours, 0.5 hours, 0.8 hours, 1 hour, 1.5 hours, 2 hours, 3 hours, 4 hours, 5 hours, etc.
[0059] In some embodiments of the present invention, the output conversion signals include low-speed operation of the indoor unit fan, high-speed operation of the indoor unit fan, low-speed operation of the electric auxiliary heating device, and high-speed operation of the electric auxiliary heating device.
[0060] In detail, in cooling mode, the electric auxiliary heating device is not activated, and the indoor unit fan runs at high speed, indicating that the air conditioner has a high cooling output efficiency. If, during the first period of operation, neither a temperature-reaching shutdown signal nor an output conversion signal is received, and the air conditioner maintains the indoor unit fan at high speed for the first period of operation, and the indoor temperature still has not reached the target temperature, then the third correction value is determined to be the first sub-correction value a (a < 0 in cooling mode), and the target temperature T1S = T1 + a. If, during the first period of operation, the indoor unit fan runs at low speed, indicating that the air conditioner has a low cooling output efficiency, if neither a temperature-reaching shutdown signal nor an output conversion signal is received, and the air conditioner maintains the indoor unit fan at low speed for the first period of operation, and the indoor temperature still has not reached the target temperature, then the third correction value is determined to be the first sub-correction value b (b < 0 in cooling mode), and the target temperature T1S = T1 + b.
[0061] Understandably, in heating mode, when the indoor unit fan is running at high speed, the second correction value is set to a (a > 0 in heating mode), and the target temperature T1S = T1 + a; when the indoor unit fan is running at low speed, the second correction value is set to b (b > 0 in heating mode), and the target temperature T1S = T1 + b; where |a| ≥ |b|.
[0062] In heating mode, when the electric auxiliary heating device is activated, the indoor unit fan must be kept at a high speed to ensure the safe operation of the electric auxiliary heating device. Specifically, when the electric auxiliary heating device is running at a high speed, it indicates that the air conditioner has a high heat output efficiency. If, during the first period of operation, neither a temperature-reaching shutdown signal nor an output conversion signal is received, and the air conditioner maintains the electric auxiliary heating device at a high speed for the first period of time, and the indoor temperature still has not reached the target temperature, then the third correction value is determined to be the third sub-correction value a' (a' > 0 in cooling mode), and the target temperature T1S = T1 + a'. When the electric auxiliary heating device is running at a low speed, it indicates that the air conditioner has a lower heat output efficiency compared to the high speed operation. If, during the first period of operation, neither a temperature-reaching shutdown signal nor an output conversion signal is received, and the air conditioner maintains the electric auxiliary heating device at a low speed for the first period of time, and the indoor temperature still has not reached the target temperature, then the third correction value is determined to be the fourth sub-correction value b' (b' > 0 in cooling mode), and the target temperature T1S = T1 + b'. In this embodiment, |a'|≥|b'|≥|a|≥|b|.
[0063] In some embodiments of the present invention, the output conversion signals include: indoor unit fan speed up, indoor unit fan speed down, electric auxiliary heating device off, electric auxiliary heating device on, electric auxiliary heating device down, and electric auxiliary heating device up.
[0064] In cooling mode, the electric auxiliary heating device is not activated. During the first time period, when the indoor unit fan speeds up (i.e., the indoor unit fan changes from a low speed to a high speed), and the control device sends a control signal to increase the indoor unit fan speed, the difference between the actual indoor temperature and the target temperature is relatively large. Therefore, it is necessary to increase the cooling capacity output efficiency of the air conditioner to meet user needs. Thus, the second correction value is set to the first correction coefficient c (c < 0 in cooling mode) corresponding to the indoor unit fan speed increase, and the target temperature T1S = T1 + c. When the indoor unit fan speeds down (i.e., the indoor unit fan changes from a high speed to a low speed), and the control device sends a control signal to decrease the indoor unit fan speed, the difference between the actual indoor temperature and the target temperature is relatively small. This allows for a reduction in the cooling capacity output efficiency of the air conditioner to meet user needs. Therefore, the second correction value is set to the second correction coefficient d (d < 0 in cooling mode) corresponding to the indoor unit fan speed increase, and the target temperature T1S = T1 + d.
[0065] In heating mode, during the first time period, when the indoor unit fan speeds up (i.e., the indoor unit fan changes from a low speed to a high speed), and the control device sends a control signal to increase the indoor unit fan speed, the difference between the actual indoor temperature and the target temperature is relatively large. Therefore, it is necessary to increase the heat output efficiency of the air conditioner to meet user needs. Thus, the second correction value is set to the first correction coefficient c (c > 0 in heating mode) corresponding to the indoor unit fan speed increase, and the target temperature T1S = T1 + c. When the indoor unit fan speeds down (i.e., the indoor unit fan changes from a high speed to a low speed), and the control device sends a control signal to decrease the indoor unit fan speed, the difference between the actual indoor temperature and the target temperature is relatively small. This allows for a reduction in the heat output efficiency of the air conditioner to meet user needs. Therefore, the second correction value is set to the second correction coefficient d (d > 0 in heating mode) corresponding to the indoor unit fan speed increase, and the target temperature T1S = T1 + d.
[0066] When the electric auxiliary heating device is started, the indoor unit fan must be kept at the high setting to ensure the safe operation of the electric auxiliary heating device. When the electric auxiliary heating device is turned off (i.e., the electric auxiliary heating device changes from the low setting to the off state), the second correction value is determined to be the third correction coefficient g1 (g1 > 0), and the target temperature T1S = T1 + g1. When the electric auxiliary heating device is turned on (i.e., the electric auxiliary heating device changes from the off state to the low setting), the second correction value is determined to be the fourth correction coefficient g2 (g2 > 0), and the target temperature T1S = T1 + g1. 2. When the electric auxiliary heating device downshifts (i.e., changes from high-level operation to low-level operation), the second correction value is determined to be the fifth correction coefficient g3 (g3 > 0), and the target temperature T1S = T1 + g3. When the electric auxiliary heating device upshifts (i.e., changes from low-level operation to high-level operation), the second correction value is determined to be the sixth correction coefficient g4 (g4 > 0), and the target temperature T1S = T1 + g4. In this embodiment, |g4| ≥ |g3| ≥ |g2| ≥ |g1| ≥ |c| ≥ |d|.
[0067] like Figure 3 As shown, in some embodiments of the present invention, the method for calculating the target temperature includes the following steps:
[0068] Step S301: Control the air conditioner to start and operate in the preset mode according to the power-on command or mode switching command.
[0069] Step S302: Obtain the control signal from the control device after the air conditioner is started;
[0070] Step S303: Determine the correction value based on the control signal;
[0071] Step S303: Obtain the first temperature of the environment where the indoor unit of the air conditioner is located at the first moment. Step S305: Determine the target temperature as the sum of the first temperature and the correction value.
[0072] In this embodiment, steps S302 to S305 are the same as steps S101 to S104, and will not be described again here.
[0073] In step S301, the air conditioner starts according to the start command issued by the control device and operates in a preset mode. By operating the air conditioner in the preset mode, without obtaining the target temperature data, it is ensured that the air conditioner can operate stably and output cooling or heating to the room stably. On the one hand, it meets the user's cooling or heating needs. On the other hand, by continuously supplying cooling or heating to the room, the indoor temperature is quickly brought to the target temperature. The control device sends a control signal to the air conditioner based on the change in indoor temperature, which is conducive to quickly calculating the target temperature based on the control signal issued by the control device and the first temperature of the current indoor unit of the air conditioner.
[0074] In some implementations, controlling the air conditioner to operate in a preset mode includes: controlling the indoor unit fan to start at a high speed and controlling the output power of the compressor 30 to be adjusted to the upper limit, so that the air conditioner can maintain the maximum cooling or heating output efficiency, shorten the calculation cycle of the target temperature, and achieve the purpose of quickly calculating the target temperature.

[0076] In this embodiment, the control device 10 is a wired controller. A temperature sensor 50 is provided at the return air vent of the indoor unit of the air conditioner. The temperature sensor 50 is used to detect the first temperature at the return air vent of the indoor unit. The control device 60 is electrically connected to the temperature sensor 50. The control device 60 receives the control signal sent by the control device 10 and determines the correction value corresponding to the control signal. The control device calculates the target temperature by calculating the sum of the first temperature and the correction value.
[0077] After calculating the target temperature, the control device controls the operation of other components in the air conditioner, such as the indoor unit fan 20, the outdoor unit fan, the electric auxiliary heating device 40, and the compressor 30, based on the target temperature.
[0078] The control device 60 includes a memory 61 and at least one processor 62. The memory 61 stores a program or instructions that can be executed on the processor 62. When the processor 62 executes the program or instructions, it implements the steps of the method for calculating the target temperature of the air conditioner in this application.
[0079] In an exemplary embodiment, the control device 10 can send Y1, Y2, W1, W2 signals to the control unit 60, wherein the Y1 signal indicates that the indoor unit fan is running at a low speed, the Y1+Y2 signal indicates that the indoor unit fan is running at a high speed, when the Y1 signal changes to the Y1+Y2 signal, it indicates that the control device sends a signal to increase the indoor unit fan speed, and when the Y1+Y2 signal changes back to the Y1 signal, it indicates that the control device sends a signal to decrease the indoor unit fan speed.
[0080] The W1 signal indicates that the electric auxiliary heating device is operating at a low speed, and the W1+W2 signal indicates that the electric auxiliary heating device is operating at a high speed. When the signal changes from Y1+Y2+W1 to Y1+Y2+W1+W2, it indicates that the control equipment sends a signal to increase the speed of the electric auxiliary heating device. When the signal changes from Y1+Y2+W1+W2 to Y1+Y2+W1, it indicates that the control equipment sends a signal to decrease the speed of the electric auxiliary heating device.
[0081] When the signal changes from Y1+Y2 to Y1+Y2+W1, it indicates that the control device has issued a signal to turn on the electric auxiliary heating device. When the signal changes from Y1+Y2+W1 to Y1+Y2, it indicates that the control device has issued a signal to turn off the electric auxiliary heating device.
