Description
Technical Field
The present invention relates to the field of air conditioner control, and in particular, to a heating control method for an air conditioner with a heating function, an air conditioner implementing the method, and a computer-readable storage medium.
Background
Most of existing air conditioners have cooling and heating functions, the air conditioners do not normally work for a long time no matter the air conditioners work in a cooling or heating mode, but judge whether cooling or heating conditions are met or not through detecting indoor environment temperature, if the cooling or heating conditions are met, the air conditioners start working, and if the cooling or heating conditions are not met, the air conditioners stop working, so that electric energy consumed by the air conditioners is saved.
Taking heating as an example, the air conditioner detects the indoor ambient temperature through an indoor ambient temperature sensor, and determines the relationship between the indoor ambient temperature and the temperature set by the user, and if the indoor ambient temperature is greater than the temperature set by the user and exceeds a certain threshold, the heating operation, for example, the compressor operation is stopped, and the operation of the indoor unit fan is stopped. During the period that the air conditioner stops heating operation, the air conditioner continuously detects the indoor environment temperature, and judges whether the indoor environment temperature is lower than a preset temperature value, if so, the air conditioner restarts and continues heating operation.
However, in the actual operation process of the air conditioner, the air conditioner can be restarted after stopping heating, that is, the indoor environment temperature is reduced, but the air conditioner still does not start heating in time, so that the indoor temperature is too low, and the use of a user is affected.
Disclosure of Invention
The first purpose of the invention is to provide an air conditioner heating control method which avoids that the air conditioner does not restart heating for a long time after stopping heating.
The second purpose of the invention is to provide an air conditioner for realizing the air conditioner heating control method.
A third object of the present invention is to provide a computer-readable storage medium for implementing the above-mentioned air conditioner heating control method.
In order to achieve the first object of the present invention, the air conditioner heating control method provided by the present invention comprises after entering a heating mode, determining whether a preset heating stop condition is met, if so, stopping heating; acquiring the temperature of the inner pipe and the temperature of the indoor environment, judging whether the temperature of the inner pipe is smaller than the temperature of the indoor environment, if so, taking the temperature of the inner pipe as the temperature of the temporary indoor environment, judging that the preset heating condition is restarted according to the temperature of the temporary indoor environment, and if so, restarting the air conditioner for operation.
The reason why the air conditioner cannot start heating for a long time after stopping heating is that a large amount of heat is accumulated around an ambient temperature sensor of an indoor unit of the air conditioner, and the ambient temperature sensor cannot accurately detect the indoor ambient temperature due to the accumulation of the heat, so that the air conditioner cannot be started in time. The invention adopts the temperature of the inner pipe to replace the indoor environment temperature as the temporary indoor environment temperature, and judges whether the condition of restarting heating is met or not by taking the temporary indoor environment temperature as the indoor environment temperature, thereby avoiding the problem that the air conditioner cannot be restarted for a long time due to inaccurate detection of the indoor environment temperature by the indoor environment temperature sensor.
And after the air conditioner stops operating for a period of time, the temperature of the inner pipe of the air conditioner is closer to the indoor environment temperature, so that the accuracy of restarting heating judgment can be improved by replacing the indoor environment temperature with the temperature of the inner pipe, the air conditioner can be restarted in time, and discomfort of a user caused by reduction of the indoor temperature is avoided.
In a preferred embodiment, the temporary indoor ambient temperature is not updated within a preset time after the air conditioner is turned on again.
After the air conditioner is restarted to heat, the numerical value of the temporary indoor environment temperature is kept unchanged for a period of time, so that the condition that the air conditioner stops heating immediately after being restarted due to the fact that the indoor environment temperature is switched to the actual sampling value of the indoor environment temperature sensor can be avoided, and the problems that the air conditioner is repeatedly started and stopped are solved.
The further scheme is that after the preset time passes, the current indoor environment temperature is obtained, the temperature value of the indoor environment temperature is updated by applying the current indoor environment temperature, and the working state of the air conditioner is determined according to the current indoor environment temperature.
After the air conditioner restarts heating operation for a period of time, the actual temperature value acquired by the indoor environment temperature sensor is used as the indoor environment temperature, so that the actual condition of the current indoor environment temperature can be more accurately reflected, and the control on the subsequent operation state of the air conditioner is facilitated, such as judging whether the condition of stopping heating is met.
The further scheme is that if the temperature of the inner pipe is not less than the indoor environment temperature, whether the heating condition is restarted is judged, and if the heating condition is restarted, the air conditioner is restarted to operate.
Therefore, when the temperature of the inner pipe is lower, the temperature of the inner pipe is not used to replace the indoor environment temperature as the temporary indoor environment temperature, and a normal control flow is executed, for example, whether the heating condition is restarted is judged.
In a further scheme, when the preset heating stopping condition is met and heating is stopped, the compressor of the air conditioner and the fan of the indoor unit are stopped.
Therefore, under the condition of stopping heating, the compressor and the indoor fan of the air conditioner stop running, and the purpose of saving electric energy is achieved.
The further scheme is that the judging whether the preset heating stopping condition is met comprises the following steps: and judging whether the indoor environment temperature reaches a preset temperature value, if so, further judging whether the inner pipe temperature is greater than the indoor environment temperature and the difference value between the inner pipe temperature and the indoor environment temperature is greater than a first preset threshold value, and if so, confirming that a preset heating stopping condition is met.
Therefore, after the temperature of the inner pipe exceeds the indoor environment temperature and reaches a first preset threshold value, the operation of the fan is stopped, and cold air blown out by the air conditioner can be avoided.
According to a further scheme, after the indoor environment temperature reaches the preset temperature value and before the preset heating stopping condition is met, the compressor of the air conditioner stops running, and the indoor unit fan runs at a low wind speed.
After the compressor stops operating, the air-conditioning indoor unit still retains certain heat, and the fan operates at low wind speed to blow out the heat retained by the air-conditioning indoor unit, so that cold air can be prevented from being blown out, and the heat retained in the indoor unit can be fully utilized.
An optional scheme is that when the preset restart condition is not met according to the temporary indoor environment temperature, the indoor unit fan operates at a low wind speed.
Further, the judging that the preset restart heating condition is met according to the temporary indoor environment temperature comprises: and judging whether the temporary indoor environment temperature is less than the set temperature or not and the difference value between the temporary indoor environment temperature and the set temperature is greater than a second preset threshold value.
Therefore, when the temporary indoor environment temperature is higher than the temperature value set by the user, heating is not stopped immediately, heating is stopped only after the temporary indoor environment temperature is lower than the second preset threshold of the set temperature, and the situation that the air conditioner is easily started and stopped repeatedly is avoided.
In order to achieve the second object, the air conditioner provided by the present invention has a housing, a circuit board is disposed in the housing, a processor and a memory are disposed on the circuit board, the memory stores a computer program, and the computer program implements the steps of the air conditioner heating control method when executed by the processor.
To achieve the third objective, the present invention provides a computer-readable storage medium having a computer program stored thereon, where the computer program is executed by a processor to implement the steps of the air conditioner heating control method.

Detailed Description
The air conditioner heating control method of the present invention is applied to an air conditioner having a heating function, and preferably, the air conditioner has an indoor unit, and the indoor unit is provided with an inner pipe temperature sensor and an indoor environment temperature sensor for detecting an inner pipe temperature and an indoor environment temperature. The indoor unit of the air conditioner is further provided with a processor and a memory, the memory stores a computer program, and the processor executes the computer program to realize the air conditioner heating control method.
The embodiment of the air conditioner heating control method comprises the following steps:
referring to fig. 1, the air conditioner heating control method of the present embodiment is applied to an air conditioner with a heating function, for example, the air conditioner has an indoor unit 10, an inner pipe temperature sensor 11 and an indoor environment temperature sensor 12 are disposed in the indoor unit 10, and the inner pipe temperature sensor 11 is disposed at the periphery of a coil of the indoor unit and is used for detecting the temperature of the coil.
The following describes the flow of the air conditioner heating control method with reference to fig. 2 and 3. First, step S21 is executed, the air conditioner enters into a heating mode after being powered on according to an instruction sent by a user, for example, the indoor unit receives an instruction sent by a remote controller, the compressor starts to operate, and the indoor unit fan starts to operate, so that the air conditioner blows hot air into the room.
Then, step S22 is executed to obtain the indoor environment temperature, and it is determined whether the indoor environment temperature reaches a preset temperature value, if so, step S23 is executed, otherwise, the indoor environment temperature continues to be detected. As the air conditioner heats and the indoor ambient temperature rises, the air conditioner stops heating when the indoor ambient temperature reaches a certain temperature, so a temperature value is usually set, and once the indoor ambient temperature is higher than the preset temperature value, the air conditioner heating operation needs to be stopped. Typically, the preset temperature value is a higher temperature value than the temperature value set by the user, for example, the user sets the air-conditioning heating temperature to be 28 ℃, and the preset temperature value may be 29 ℃.
If the judgment result of the step S22 is yes, the step S23 is executed to stop the operation of the compressor of the air conditioner, but the indoor unit fan does not stop the operation immediately, but continues the operation in the low wind speed mode. Because the air conditioner produces the hot-air under the heating mode indoor set, after the compressor stops working, a large amount of hot-air still remains in the indoor set, if the compressor stops working the indoor set fan also stops working, the hot-air that the air conditioner indoor set was left will be unable in time to get rid of the indoor set, leads to thermal waste.
Then, step S24 is executed to obtain the temperature of the inner pipe, and determine whether the temperature of the inner pipe is greater than the indoor ambient temperature by a first preset threshold, if yes, step S25 is executed, otherwise, step S23 is executed again, i.e. the compressor is kept in the stopped state, but the indoor unit fan is kept operating in the low wind speed mode.
In step S24, the temperature of the inner pipe is obtained by the inner pipe temperature sensor 21, and compared with the indoor environment temperature, if the temperature of the inner pipe is greater than the indoor environment temperature, and the difference between the temperature of the inner pipe and the temperature of the indoor environment is greater than the first preset threshold, the judgment result in step S24 is yes, step S25 is executed, and the operation of the indoor unit fan is stopped. Preferably, the first preset threshold is 2 ℃.
If the compressor stops running, the indoor unit fan stops running immediately, which easily causes the air conditioner to blow out cold air, therefore, the operation of the indoor unit fan is not stopped immediately after the compressor stops running, but the indoor unit continues running for a period of time at a low wind speed. Because the condition that the operation of the fan of the indoor unit is stopped is that the temperature of the inner pipe is higher than the temperature of the indoor environment, the temperature of the inner pipe is higher than the temperature of the indoor environment before the operation of the fan of the indoor unit is stopped, cold air which is lower than the temperature of the indoor environment can be prevented from being blown out from an air conditioner, and users can be prevented from feeling uncomfortable.
After the indoor unit fan stops operating, step S26 is executed to determine whether the temperature of the inner pipe is lower than the indoor ambient temperature. Specifically, the inner tube temperature of the indoor unit is acquired by the inner tube temperature sensor 11, and the indoor ambient temperature is acquired by the indoor ambient temperature sensor 12, and the inner tube temperature and the indoor ambient temperature are compared, the inner tube temperature and the indoor ambient temperature are compared in magnitude, if the inner tube temperature is less than the indoor ambient temperature, step S27 is executed, otherwise, step S28 is executed.
In step S27, the temperature of the inner tube collected by the inner tube temperature sensor is used to replace the indoor ambient temperature as a temporary indoor ambient temperature, that is, a temporary indoor ambient temperature is set, and the temporary indoor ambient temperature is the temperature of the inner tube collected by the inner tube temperature sensor. Because the temperature of the inner pipe is closer to the temperature of the indoor environment under the condition that the temperature of the inner pipe is lower, and because the inner pipe temperature sensor is arranged at the periphery of the coil pipe of the indoor unit, a large amount of gathered heat is not easy to generate at the periphery of the coil pipe, namely the inner pipe temperature sensor is not easy to be influenced by heat gathering, the collected temperature can accurately reflect the actual temperature of the inner pipe, and the actual temperature of the indoor environment is more accurately reflected. Therefore, step S27 using the inner tube temperature as the temporary indoor environment temperature can provide more accurate data for the subsequent determination of whether the restart heating condition is satisfied.
After the step S27 is executed, the step S29 is executed to determine whether the preset restart heating condition is satisfied. Specifically, the temporary indoor environment temperature set in step S27 is used as a judgment basis, for example, the temporary indoor environment temperature is compared with a temperature value set by a user, and whether the temporary indoor environment temperature is less than the temperature set by the user is judged, and a difference between the temporary indoor environment temperature and the temperature set by the user is greater than a second preset threshold.
For example, if the temporary indoor ambient temperature set at step S27 is 26 ℃, the user-set temperature is 28 ℃, it may be confirmed that the temporary indoor ambient temperature is less than the user-set temperature, and the difference between the temporary indoor ambient temperature and the user-set temperature is 2 ℃. At this time, it is also necessary to determine whether the difference is greater than the second preset threshold in step S29, and if the second preset threshold is 1 ℃, it may be determined that the difference is greater than the second preset threshold, and the determination result in step S29 is yes. If the temporary indoor ambient temperature is not less than the temperature set by the user, the judgment result of step S29 is no. Alternatively, if the temporary indoor ambient temperature is less than the temperature set by the user, but the difference between the temporary indoor ambient temperature and the temperature set by the user is not greater than the second preset threshold, the result of the determination in step S29 is no.
If it is determined that the restart heating condition is not satisfied using the temporary indoor ambient temperature as a basis, the process returns to step S23, the compressor of the air conditioner continues to be maintained in a stopped state, and the indoor unit fan is operated in a low wind speed mode. If it is confirmed that the re-turn-on heating condition is satisfied using the temporary indoor ambient temperature as a basis, step S30 is performed, the air conditioner is turned on again and enters the heating mode after being turned on, and furthermore, the air conditioner does not update the temporary indoor ambient temperature for a preset time. For example, after the air conditioner is turned on again, the compressor and the indoor unit fan operate normally, and the air conditioner enters a heating mode, and the air conditioner blows out hot air. In addition, the temporary indoor environment temperature is not updated within a period of time, for example, within 3 minutes, that is, the inner tube temperature is not collected within the preset time, and the inner tube temperature is not updated, so that the temporary indoor environment temperature is not updated.
The purpose of not updating the temporary indoor environment temperature within the preset time is to avoid the situation that the air conditioner is repeatedly started and stopped because the air conditioner reaches the condition of stopping heating immediately after the air conditioner restarts heating operation. Specifically, if the temporary indoor environment temperature is not set within the preset time and is not updated, that is, the temperature value acquired by the indoor environment temperature sensor is directly adopted as the indoor environment temperature and the judgment of whether the preset heating stop condition is met is performed, then because the temperature value acquired by the indoor environment temperature sensor is higher, the judgment result will be that the preset heating stop condition is met, the condition of stopping heating is immediately judged to be met after the air conditioner restarts to heat, the operation time of the air conditioner after restarting is extremely short, and the air conditioner cannot effectively heat.
After the step S30 is executed, step S31 is executed to determine whether a preset time is reached, that is, whether a preset time has elapsed since the air conditioner restarts heating, for example, whether 3 minutes has elapsed since the air conditioner restarts heating, if not, the waiting is continued, and if yes, step S32 is executed to obtain the current indoor ambient temperature and update the temperature value of the indoor ambient temperature by using the current indoor ambient temperature. Since the step S27 uses the inner tube temperature instead of the indoor ambient temperature to determine whether the condition for restarting the heating is satisfied, the determinations in the steps S29 to S31 are all based on the temporary indoor ambient temperature. After the preset time has elapsed, the indoor ambient temperature needs to be updated, and at this time, the temperature data collected by the indoor ambient temperature sensor 12 is used, and the temperature data collected by the indoor ambient temperature sensor 12 is used as the current indoor ambient temperature, and the current indoor ambient temperature is used as the actual indoor ambient temperature.
And finally, executing step S33 to determine whether a shutdown command sent by the remote controller is received, if the shutdown command is not received, the air conditioner needs to continue to operate, at this time, returning to step S21, the air conditioner maintains the heating mode to operate, and executing step S22 to determine whether the indoor ambient temperature reaches a preset temperature value. Since the indoor ambient temperature is updated in step S32, the determination target in step S22 is the indoor ambient temperature updated in step S32, that is, the data collected by the indoor ambient temperature sensor.
After the preset time, whether the indoor environment temperature meets the preset heating stopping condition or not is determined by adopting the data collected by the indoor environment temperature sensor, so that the judgment of the heating stopping condition of the air conditioner is more accurate, the air conditioner stops working when meeting the preset condition, the electric energy consumed by the air conditioner is saved, and the long-time working of the air conditioner is avoided.
If the judgment result in the step S33 is yes, the indoor unit of the air conditioner receives the instruction of stopping the operation sent by the remote controller, and the air conditioner is turned off.
If the result of the judgment in the step S26 is no, the air conditioner restarts and enters a heating mode when the air conditioner satisfies a preset restart heating condition in execution of the step S28. Since the data collected by the indoor environment temperature sensor is not replaced by the inner tube temperature before the step S26 to be the temporary indoor environment temperature, the step S28 uses the data collected by the indoor environment temperature sensor to determine whether the preset condition for restarting heating is satisfied, that is, whether the indoor environment temperature is lower than the temperature set by the user, and the difference between the indoor environment temperature and the temperature set by the user is greater than the second preset threshold, if the above condition is satisfied, it is determined that the current state satisfies the condition for restarting heating, and the air conditioner restarts to operate and enters the heating mode.
Subsequently, step S32 is executed to acquire a temperature value collected by the indoor environment temperature sensor, and update the indoor environment temperature with the temperature value collected by the indoor environment temperature sensor. Therefore, the air conditioner does not set the temporary indoor environment temperature, but directly adopts the data collected by the indoor environment temperature sensor to judge whether the air conditioner meets the conditions of restarting heating and stopping heating.
The inventor finds that the reason that the existing air conditioner cannot be started for a long time after heating is stopped is that a large amount of heat exists around the indoor environment temperature sensor, namely, the heat is accumulated, so that the temperature value detected by the indoor environment temperature sensor is inaccurate, and further, whether the temperature value is restarted or not is influenced.
The condition of whether this embodiment adopts the inner tube temperature to satisfy restart heating as interim indoor ambient temperature to the air conditioner judges, because the peripheral heat that is difficult to gather of inner tube temperature sensor, can effectively avoid leading to the inaccurate problem that leads to the long-time unable restart of air conditioner because of the temperature data that the heat gathering leads to temperature sensor to gather. And because the temperature of the inner pipe is closer to the indoor environment temperature under a certain condition, the temperature of the inner pipe is adopted to replace the indoor environment temperature to judge whether the air conditioner needs to be restarted or not, the air conditioner can be accurately and timely restarted and heated, and the condition that the user is uncomfortable because the air conditioner cannot be restarted for a long time is avoided.
