Background
In the process of using the heating mode of the air conditioner, the running capability of the air conditioner is influenced because the condenser of the outdoor air conditioner frosts too thick, and the air conditioner is set to automatically switch to the defrosting mode when finding that the frost layer is too thick. After defrosting is finished, the indoor inner coil pipe is always in a state of low temperature, along with the operation of a heating mode, the temperature of the inner coil pipe gradually rises, the inner fan rotating speed can be controlled by the inner fan controller to be increased in stages until the temperature of the inner coil pipe reaches a high temperature, then the rotating speed of the inner fan is switched to be a normal rotating speed to blow, and the time of stopping the inner fan after defrosting and the time of low rotating speed is called as a cold air prevention stage.
In the existing cold air prevention stage, if the temperature of the inner coil pipe is too low when defrosting is finished, the temperature of the inner coil pipe rises slowly, so that the time of the whole cold air prevention stage is too long. Under the condition, the user air conditioner can not be heated for a long time in the using process, and the experience degree of the user air conditioner is influenced.

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.
It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For easy understanding, in the present invention, technical problems therein need to be elaborated.
The defrosting mode of the air conditioner is relatively similar to the cooling mode, and therefore, in order to prevent cold air from blowing from the indoor unit to the indoor environment, the operation of the inner fan is generally stopped until the defrosting mode is exited.
After the air conditioner exits from the defrosting mode, the inner coil of the indoor unit is often in a state with too low temperature, and after the air conditioner is switched to the heating mode, in order to prevent the indoor unit from blowing out cold air, the shutdown state of the inner fan is generally kept until the temperature of the inner coil is recovered to a certain degree, the rotating speed of the inner fan is controlled to be increased in stages (the lower the temperature of the inner coil is, the smaller the rotating speed of the inner fan is, so that the cold air is prevented from being blown out), until the temperature of the inner coil reaches a higher temperature, the rotating speed of the inner fan is switched to be normal rotating speed for blowing, and the shutdown and low rotating speed time of the.
The longer the air conditioner runs in the defrosting mode, the lower the temperature of the inner coil pipe is when the air conditioner exits the defrosting mode, and the longer the duration of the cold air prevention stage is; the air conditioner can not normally heat in the cold air prevention stage, the condition that the air conditioner does not heat for a long time appears in the air conditioner using process caused by the overlong cold air prevention stage time, the normal air conditioner is greatly influenced, and the comfort level and the experience degree of a user can be greatly reduced.
The disclosed embodiments provide a cold-proof wind control method, which may be performed by a cold-proof wind control device that may be integrated in an electronic apparatus such as an air conditioner. Fig. 1 is a flowchart illustrating a cold-air prevention control method according to an embodiment of the present invention; the cold air prevention control method comprises the following steps:
the inner ring temperature refers to the indoor environment temperature of the indoor unit; the temperature of the inner coil pipe refers to the temperature of the inner coil pipe of the indoor unit.
The temperature of the inner ring can be obtained by measuring by a temperature sensor in the air conditioner, or can be obtained by performing temperature compensation on a measured value after measurement; but may also be obtained by other means such as calculation and the like. It should be noted that the inner ring temperature in this application is a real-time temperature.
The temperature of the inner coil can be obtained by measuring by a temperature sensor at the side of the inner coil in the air conditioner, or can be obtained by performing temperature compensation on a measured value after measurement; but may also be obtained indirectly by other means such as calculation and the like. It should be noted that the temperature of the inner coil is a real-time temperature in this application.
wherein, the difference value between the inner ring temperature and the inner coil temperature is the value obtained by subtracting the inner coil temperature from the inner ring temperature; in the case that the inner ring temperature is greater than the inner coil temperature, the difference is a positive value; in the case where the inner ring temperature is less than the inner coil temperature, the difference is negative.
And step 40, if the difference value between the temperature of the inner ring and the temperature of the inner coil is greater than a first threshold value, controlling the inner fan to operate at a first rotating speed until the difference value between the temperature of the inner ring and the temperature of the inner coil is less than the first threshold value.
Wherein the inner ring temperature and the inner coil temperature are obtained in real time; controlling the inner fan to operate at a first rotating speed, wherein the specific operation can be that the target rotating speed of the inner fan is set to be the first rotating speed, and then the rotating speed of the inner fan is adjusted according to a preset control logic; other operations can be performed, and the actual conditions are subject to the standard.
When the difference between the inner ring temperature and the inner coil temperature is greater than a first threshold, it means that the difference between the inner ring temperature and the inner coil temperature is greater. Under this kind of condition, the operation of fan in carrying out can be so that the air of indoor hot-air and interior coil pipe department forms air cycle to carry out the heat transfer with the interior coil pipe of low temperature and the indoor hot-air of higher temperature, through this kind of heat transfer, can improve the temperature of interior coil pipe, and then shorten the time of preventing cold wind stage.
The value range of the first rotating speed is 300-800 r/min. Thus, the heat exchange between the inner coil and the indoor hot air can be improved, and the temperature of the inner coil is improved (further improved on the basis of the original temperature rising measure of the inner coil).
In this step, the inner fan is controlled to operate at the first rotation speed as long as the difference is greater than the first threshold, and the control is stopped only after the difference is less than the first threshold. The specific implementation logic of this step may be: acquiring a difference value between the temperature of the inner ring and the temperature of the inner coil in real time, controlling the inner fan to operate at a first rotating speed when the difference value is greater than a first threshold value, and then judging the relation between the difference value and the first threshold value again to form a judgment and execution cycle; other logic may be used as long as the above object can be achieved, and other modifications may be made in addition to the above object.
It should be noted that in this step, after the difference is no longer greater than the first threshold, step 30 is executed again, and the difference is determined according to the real-time inner ring temperature and the inner coil temperature.
Optionally, the value range of the first threshold is 15 ℃ to 25 ℃. Through the setting of the first threshold value, the temperature of the inner coil can be increased through heat exchange under the condition that the temperature of the inner ring and the temperature of the inner coil have a larger difference; so on the one hand can improve the efficiency of heat exchange, on the other hand can also avoid blowing under the not high condition of heat exchange efficiency, and then prevents to reduce user's comfort level owing to blowing.
Like this, through step 20 ~ 40, can be when the temperature difference of inner ring temperature and interior coil pipe temperature is great, through the temperature of coil pipe in the heat exchange improvement to shorten the time of preventing cold wind stage, improve user's comfort level and experience.
Optionally, as shown in fig. 2, the step 20 includes, after the air conditioner defrosting mode is finished and before the inner ring temperature and the inner coil temperature are obtained:
and step 10, after the air conditioner enters a defrosting mode, adjusting the angle of an air guide door of the air conditioner.
It should be noted that the comfort level of the user is reduced by blowing cold air from the air conditioner, mainly because the cold air blown from the air conditioner causes a sense of temperature drop; in fact, the influence of the cold air blown out from the air conditioner on the inner loop temperature (especially in a short time) is small, so that the comfort of the user is reduced, and the cold air blown out from the air conditioner is generally blown to the user.
In this step, the angle of the air guide door is adjusted to prevent the blown cold air from blowing to the user.
Therefore, by adjusting the angle of the air guide door, the situation that the comfort level is reduced when cold air blown out by the indoor unit blows to a user can be avoided.
It should be noted that, after an instruction for adjusting the angle of the air guiding door is sent to the air conditioner, the air conditioner adjusts the angle of the air guiding door with a certain hysteresis, and the angle of the air guiding door is adjusted directly after the air conditioner enters the defrosting mode, instead of adjusting the angle of the air guiding door after the defrosting mode is finished, so that the condition that the angle of the air guiding door is not adjusted yet when the inner fan is operated is avoided, and cold air blows people is avoided; and the fan is in the shutdown state during the defrosting, and the angle adjustment of the air guide door does not bring influence to actual air outlet during the defrosting, so that the comfort of the air conditioner can be better ensured before the defrosting is finished.
Optionally, the angle of the air conditioner air guide door is adjusted to be reduced by 15 to 25 degrees.
Like this through the angle that reduces the air guide door, can be so that the direction of blowing of air guide door upwards adjusts to avoid cold wind direct-blow user.
Optionally, the angle of the air guide door is reduced by 15-25 degrees based on the default angle of the air guide door, so that cold air can be prevented from being blown directly.
Optionally, the angle of the air guide door of the air conditioner is adjusted to be a preset angle. Can directly confirm the angle that can avoid cold wind direct-blowing like this according to actual conditions, as this angle of predetermineeing, avoid because the influence that the difference of acquiescence angle brought for final effect (when acquiescence angle is too big, the wind-guiding door after reducing still probably blows the user).
Optionally, whether the defrosting mode of the air conditioner is finished is judged according to the running condition of the compressor, the air conditioner stops the compressor when the defrosting is finished, therefore, whether the compressor is stopped is judged in the defrosting mode, if the compressor is stopped, the defrosting of the air conditioner enters an end stage (in control, in order to control the air conditioner accurately, the end and the switching of the defrosting mode can be carried out after the compressor is stopped for a period of time, and the time of a cold air prevention stage can be increased).
Optionally, as shown in fig. 3, in step 10, after the air conditioner enters the defrosting mode, adjusting the angle of the air guide door of the air conditioner includes:
and step 12, adjusting the angle of the air guide door of the air conditioner after the defrosting time is longer than a first preset time.
By recording the defrosting time, the angle of the air guide door can be adjusted after the air conditioner enters the defrosting mode for a period of time (first preset time); on one hand, the unstable state of the air conditioner in a short time when the air conditioner enters the defrosting mode can be avoided; in addition, on the one hand, the angle of the air guide door can be adjusted in the defrosting mode, so that the condition that cold air blows people due to the fact that the angle of the air guide door is not adjusted when the inner fan operates is avoided.
The angle adjustment of the air guide door during the defrosting process can ensure that cold air at the air outlet blows upwards after the defrosting stage is finished and does not blow users directly.
Optionally, the value range of the first preset time is 2-4 min. Therefore, on one hand, the air conditioner can stably run in a defrosting mode, on the other hand, the time for adjusting the angle can be controlled in the defrosting mode, and the condition that the angle of the air guide door is not adjusted when the inner fan operates due to the fact that the defrosting time of the air conditioner is too short is avoided.
Optionally, as shown in fig. 4, after the step 30 of determining a difference between the inner ring temperature and the inner coil temperature according to the inner ring temperature and the inner coil temperature, the method includes:
and step 50, if the difference value between the temperature of the inner ring and the temperature of the inner coil is greater than zero and smaller than the first threshold value, controlling the inner fan to operate or stop operating at a second rotating speed until the difference value between the temperature of the inner ring and the temperature of the inner coil is smaller than zero.
The method comprises the following steps of controlling an inner fan to operate at a second rotating speed, wherein the specific operation can be that the target rotating speed of the inner fan is set to be the second rotating speed, and then the rotating speed of the inner fan is adjusted according to a preset control logic; other operations can be performed, and the actual conditions are subject to the standard.
In this step, the inner fan is controlled to operate at the second rotation speed as long as the difference is smaller than the first threshold and larger than zero, and the control is stopped only after the difference is smaller than zero. The specific implementation logic of this step may be: acquiring a difference value between the temperature of the inner ring and the temperature of the inner coil in real time, controlling the inner fan to operate at a first rotating speed when the difference value is larger than zero and smaller than a first threshold value, and then judging the relation between the difference value and zero again to form a judgment and execution cycle; other logic may be used as long as the above object can be achieved, and other modifications may be made in addition to the above object.
Optionally, the second rotational speed is lower than the first rotational speed.
When the difference between the inner ring temperature and the inner coil temperature is less than a first threshold, it means that the difference between the inner ring temperature and the inner coil temperature is small. Under this kind of condition, the operation of fan in carrying out for the air of indoor hot-air and interior coil pipe department forms air cycle, and what this kind of air circulated, brought is the flow of air, and the air flow itself can produce the body of cooling and feel (to the user), still can influence the programming rate of temperature of interior coil pipe, consequently, compares the interior fan of first rotational speed operation, and the rotational speed of fan in need reducing reduces, reduces the speed that the air flows, thereby the influence of less air flow to interior coil pipe programming rate.
In addition, when the difference value of the temperatures is reduced to a certain range, the rotating speed of the inner fan is subjected to second rotating speed or stop control, so that the temperature rise condition of the inner coil pipe can be prevented from being influenced; the rotating speed of the inner fan is reduced to the second rotating speed, so that the low wind speed condition is maintained, and the noise influence is small in the subsequent rotating speed switching and changing process of the inner fan; through shutting down interior fan, because interior fan is bloied when the difference of temperature is less and is lower to the heat transfer effect influence, avoids causing the influence for interior coil pipe rate of rising temperature when interior coil pipe temperature surpasss interior ring temperature simultaneously, guarantees to reach the interior coil pipe temperature of target in the shortest time for air guide door adjustment back air-out temperature is suitable temperature promptly.
It should be noted that in this step, after the difference is no longer greater than the other, step 30 is executed again, and the difference is determined according to the real-time inner ring temperature and the inner coil temperature.
Optionally, the value range of the second rotation speed is 200-400 r/min. Therefore, the noise influence in the subsequent inner fan rotating speed switching change process is small.
Optionally, as shown in fig. 5, after the step 30 of determining a difference between the inner ring temperature and the inner coil temperature according to the inner ring temperature and the inner coil temperature, the method includes:
and step 60, if the difference value between the inner ring temperature and the inner coil temperature is less than zero, switching the air conditioner to a preset control mode.
Wherein, the inner ring temperature with the difference of interior coil pipe temperature is less than zero, means that can't carry out the heat exchange through indoor hot-air and interior coil pipe and improve the temperature of interior coil pipe, under this condition, can withdraw from the control method of this application, and then take original defrosting operation logic: the inner machine controller can control the rotating speed of the inner fan to be increased in stages until the temperature of the inner coil pipe reaches a higher temperature, and then the rotating speed of the inner fan is switched to be the normal rotating speed to blow air. The temperature of the inner coil is controlled to be raised.
The preset control mode is the existing defrosting control logic (i.e. the control logic for restoring the heat recovery mode after the defrosting mode is finished in the prior art), and the control logic of the preset control mode can be adjusted according to the actual situation.
Therefore, after the difference value is smaller than zero, the original preset control mode is switched to, the temperature rise control of the temperature of the inner coil can be carried out, and the normal operation of the air conditioner is ensured.
Optionally, the switching the air conditioner to the preset control mode further includes:
and adjusting the angle of the air guide door to be a default angle. In this way, the damper angle can be restored, thereby avoiding interference with normal heating and defrost operating logic.
The embodiment of the present disclosure provides a cold air prevention control device for performing the cold air prevention control method according to the above aspects of the present disclosure, and the cold air prevention control device is described in detail below.
