Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic flow chart of a method for controlling reliable operation of electric heating of an air conditioner according to an embodiment of the present invention, the method including:
and S102, starting electric heating and acquiring the temperature rising rate of the inner disc.
Before the electric heating is started, the air guide door, the compressor and the indoor fan need to be controlled to be opened.
And under the heating mode, opening the air guide door, opening the compressor, opening the indoor fan after the cold air prevention mode is finished, detecting whether the electric heating opening condition is met, and opening the electric heating when the electric heating opening condition is met. Optionally, if the temperature of the inner disc is lower than a preset temperature threshold, it is determined that the electric heating starting condition is met and the electric heating is started. Under the condition that above-mentioned inner disc temperature is less than preset temperature threshold value, interior machine air-out temperature is lower, blows cold wind phenomenon promptly, and user's experience is poor, need to open the electrical heating and supply the heating capacity.
And after the electric heating is started, detecting the temperature value of the inner disc in real time, and calculating the temperature rising rate of the inner disc. Specifically, the timing may be started from the time when the electric heating is turned on, the inner tray temperature values are detected every other period (e.g., 1 second), and the temperature values are stored, and the temperature increase rate may be obtained by dividing the difference between two adjacent inner tray temperature values by the period duration, for example, the temperature increase rate may be calculated according to the following formula:
Velectrical heating＝(TCurrent period of time－TLast cycle) Period/cycle
And S104, comparing whether the temperature rising rate is greater than or equal to a preset rate threshold value.
If the air guide door is not normally opened, including the air guide door is not completely opened or is in a half-open state, or the inner fan is not normally operated, the heat of electric heating is accumulated in the inner fan, the temperature rising rate is obviously higher than the normal temperature rising rate, and finally overheating deformation or fire danger is caused.
In order to prevent the above danger, the temperature rising rate may be compared with a preset rate threshold, and if the temperature rising rate is greater than or equal to the rate threshold, it indicates that the air guide door is not normally opened and/or the inner fan is not normally operated, and at this time, the electric heating needs to be turned off. If the air guide door and the inner fan are not normally opened, the temperature of the inner disc can be rapidly increased due to the fact that the inner fan is electrically heated and operated in a relatively closed space, and the speed threshold value can be determined according to the corresponding temperature increase speed when the maximum power of electric heating is started under the condition that the minimum opening gear of the air guide door and the minimum rotating speed gear of the inner fan are used.
In the existing scheme of controlling whether the electric heating is closed or not by comparing the size relationship between the temperature of the inner disc and the preset temperature, when the air guide door is normally opened, the electric heating is closed when the temperature of the inner disc rises to a certain temperature; however, when the damper is not normally opened, the temperature of the inner panel may not rise to the electric heating off temperature, but the temperature of the electric heating part may be too high, or when the temperature of the inner panel rises to the electric heating off temperature, the absolute temperature of the electric heating part may be very high, and thus deformation and fire hazard due to overheating of electric heating may occur more easily.
In this embodiment, whether the electric heating is turned off or not is controlled by comparing the temperature increase rate with the preset rate threshold, which can be found and processed at the initial stage of the abnormal rapid temperature increase, and at this time, the absolute temperature at the electric heating part is not yet increased to a dangerous degree, that is, the overheating danger is found and processed in advance.
And S106, if so, controlling the electric heating to be closed.
If the temperature rising rate is larger than or equal to a preset rate threshold value, controlling the electric heating to be closed; and if the temperature rising rate is smaller than the rate threshold value, controlling the electric heating to continue running.
According to the method provided by the embodiment, the temperature rising rate of the inner disc is obtained after the electric heating is started, and the electric heating is controlled to be closed under the condition that the temperature rising rate is greater than or equal to the rate threshold value, so that the high-temperature deformation and fire danger of the plastic part caused by electric heating dry burning under the condition that the air guide door is not normally opened or the inner fan is not normally operated are avoided.
Considering that the interior of the indoor unit is still in a high-temperature state after the electric heating is turned off, the inner fan needs to be controlled to continuously operate at the highest rotating speed for the first time period and then stop so as to dissipate the heat in the interior of the indoor unit to the indoor space as soon as possible. The first time period may take a value of 3-5 min.
In order to improve the accuracy of detecting the electric heating fault, the steps of obtaining and comparing the temperature rising rate can be repeatedly executed for multiple times, and when the execution results of the multiple continuous times are all the control electric heating to be turned off, namely the results of the repeated execution of the steps are all the control electric heating to be turned off, and the execution result of controlling the electric heating to continue to operate does not appear, the electric heating fault is determined to appear. Based on this, the above method further comprises: repeatedly executing the steps of starting electrical heating, obtaining the temperature rising rate and comparing whether the temperature rising rate is greater than or equal to the rate threshold value; and if the electric heating is controlled to be closed for N times continuously, the compressor is controlled to stop, and the inner fan continuously operates at the highest rotating speed for a second time and then stops. N can take the value of 3-6.
In the above-mentioned process of obtaining and comparing many times, the wind-guiding door may have opened normally or the interior fan has operated normally, under this situation, after opening the electric heating, the temperature rising rate of the inner disc is the normal value, and it is less than the speed threshold value that presets, therefore need not to control the electric heating again and close. If the air guide door is still not normally opened or the inner fan is still not normally operated, the continuous multiple execution results are that the electric heating is controlled to be closed, and the situation that the electric heating is controlled to continue to operate does not occur, and at the moment, the electric heating fault is determined to occur, the electric heating is not only required to be kept closed, but also the compressor is required to be controlled to stop, and the inner fan is required to be continuously operated at the highest rotating speed for the second time and then is stopped. The second duration may take on the value of 1-2 min.
After the electric heating is controlled to be closed, the compressor is stopped and the inner fan continuously operates at the highest rotating speed for the second time and then stops, an electric heating fault code can be displayed or electric heating fault alarm can be carried out so as to prompt a user to check whether the air conditioner is abnormal in operation state, and the operation state of the air guide door and the operation state of the inner fan are mainly checked.

and S201, starting a heating mode.
S202, opening a guide air door and opening a compressor to operate
And S203, starting the indoor fan after the cold air prevention stage is finished.
Because the temperature of the evaporator is low when the heating mode is started, if the indoor fan blows air immediately at the moment, cold air is blown out, and therefore a cold air prevention stage is arranged. After the heating is started, firstly, air is not blown temporarily, when the temperature of the evaporator rises to a certain value, the fan is started to blow air, and at the moment, the blown air is hot air.
And S204, judging whether the electric heating starting condition is met. If yes, go to S205; if not, the process is ended.
And S205, turning on electric heating.

S208, continuously operating the inner fan at the highest rotating speed t1And stopping running after the time is long.
The above steps S203 to S208 are repeatedly performed.
S209, judging whether to continuously turn off the electric heating for N times. If yes, go to S210; if not, the process is ended.
S210, stopping the compressor, and operating the inner fan at the highest rotating speed t2And stopping the operation after the time is long.
S211, displaying a fault code, giving a buzzer alarm, and reminding a user to check whether the running state of the air conditioner is abnormal.
According to the embodiment, the temperature of the inner disc is detected in real time after the electric heating is started, so that the high-temperature deformation and even the fire danger of the plastic part caused by the electric heating dry burning due to the fact that the air guide door is not normally opened are avoided; when the temperature of the inner disc is detected to be abnormally and rapidly increased, fault reminding is carried out, and a user is reminded of abnormal detection.
