In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but 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 application.
Before introducing the embodiments of the present application, an application context of the embodiments of the present application is explained first:
in daily life, the use of air conditioners is becoming more and more popular. In the air conditioner heating process, because the hot air can rise automatically, the situation that the hot air is gathered at the upper part of a room can occur in the automatic up-and-down swinging process of an air conditioner air deflector, and a hang-up air conditioner is generally hung at a higher position, so that the hot air can circulate at the upper part of the room all the time, the air inlet temperature of the air conditioner is high, and the air outlet temperature is higher. Such circulation may cause the hot air to circulate in the upper part of the room as shown in fig. 1, and the user may not experience the heating effect. Moreover, the normal use of the air conditioner is affected by the over-high temperature of the indoor unit of the air conditioner.
In the prior art, when the temperature of an evaporator in an indoor unit is detected to reach a set temperature, the frequency of a compressor can be reduced, so that the normal use of an air conditioner cannot be influenced by overhigh temperature of the indoor unit.
However, in this way, the heating effect is further affected.
In view of the above problems, the inventive concept of the present application is as follows: after the temperature of the evaporator is detected to reach the set temperature, the rotating speed of the fan and the mode of the air guide plate are adjusted, so that hot air blown out of the air conditioner and indoor cold air can exchange heat better, and the heating effect of the air conditioner can be improved to a certain extent. Then, the temperature of the evaporator is collected, and when the temperature reaches the set temperature, the overheating protection mechanism is started. The application provides an overheating protection control method capable of improving the thermal effect of air modulation to a certain extent.
Hereinafter, the technical means of the present application will be described in detail by specific examples.
It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a control method for overheat protection of an air conditioner according to an embodiment of the present application. As shown in fig. 2, the control method of the air conditioner overheating protection may include the steps of:
The method provided by the application can be executed by an air conditioner. The air conditioner can be an air conditioner hanging machine or a vertical air conditioner with a transverse air deflector. The air conditioner can obtain a first temperature of a current evaporator in an indoor unit, a first mode of a current air deflector in the indoor unit and a first rotating speed of a current fan in the indoor unit.
Specifically, an average value of the surface temperature of the evaporator may be collected by a temperature sensor in the evaporator, and the average value may be used as the first temperature of the evaporator.
One or two strip-shaped injection molding parts are arranged at the air outlet of the indoor unit of the air conditioner and are air deflectors. The air deflector can be used for controlling the air outlet angle and setting high-low air sweeping. There are generally five modes of wind deflectors, including: the upper blow mode (controlling wind to blow upwards), the lower blow mode (controlling wind to blow downwards), the middle mode (controlling wind to blow towards the middle), the upper middle mode (controlling wind to blow towards the obliquely upper direction) and the lower middle mode (controlling wind to blow towards the obliquely lower direction).
Specifically, in the air-conditioning heating mode, hot air around the evaporator can be blown to the indoor through a fan in the indoor unit, so that forced convection is carried out, the indoor temperature is raised, and the purpose of adjusting the indoor air temperature is achieved. Wherein, the faster the rotational speed of fan, the more the amount of wind that produces just is big, and under the same condition, indoor temperature just also is fast that rises just more.
The preset threshold is a temperature value preset according to actual conditions, and may be set to 58 degrees celsius, for example.
Specifically, if it is determined that the first temperature of the currently-collected evaporator is greater than or equal to the preset threshold, the mode of the air deflector and the rotating speed of the fan can be adjusted through the first mode of the currently-collected air deflector and the first rotating speed of the currently-collected fan, so that the purpose of strengthening indoor air circulation is achieved, hot air circulates on the upper portion of a room, the whole room meets the heating requirement as much as possible, and the heating effect of the air conditioner is improved.
Specifically, because the hot air can automatically rise upwards, the air can be blown downwards through the lower blow molding mode of the air deflector, so that the indoor air circulation is enhanced; the rotating speed of the fan can be increased to provide heat circulation supplement air, and further indoor air circulation is enhanced.
Specifically, the mode of the air deflector is adjusted, and the second temperature of the evaporator can be acquired after the rotating speed of the fan is adjusted for a period of time.
In step 203, if it is determined that the second temperature is greater than or equal to the preset threshold, a preset overheat protection mechanism is started.
The preset overheat protection mechanism is a preset overheat protection mechanism for the indoor unit of the air conditioner. The preset overheat protection mechanism is to ensure that the normal use of the air conditioner is not influenced by the overhigh temperature of the indoor unit through some mechanisms. For example, the mechanism may be to reduce the frequency of the compressor in the air conditioner, and specifically, the preset overheat protection mechanism is not limited in this embodiment. Specifically, the frequency of the compressor is reduced, so that the temperature of the evaporator can be reduced, and the normal use of the air conditioner cannot be influenced by overhigh temperature of the indoor unit.
Specifically, after the mode of the air deflector and the rotating speed of the fan are adjusted for a period of time, the acquired second temperature of the evaporator can be compared with a preset threshold, and if the second temperature is determined to be greater than or equal to the preset threshold, a preset overheat protection mechanism is started.
Further, if it is determined that the second temperature is less than the preset threshold, the preset overheat protection mechanism is not started, and step 201 is continuously executed.
The application provides a control method for air conditioner overheat protection, which comprises the following steps: the method comprises the steps of obtaining a first temperature of an evaporator in an indoor unit of the air conditioner, a first mode of an air deflector in the indoor unit and a first rotating speed of a fan in the indoor unit; if the first temperature is determined to be greater than or equal to the preset threshold, adjusting the mode of the air deflector and the rotating speed of the fan according to the first mode and the first rotating speed, and acquiring a second temperature of the evaporator; and if the second temperature is determined to be greater than or equal to the preset threshold value, starting a preset overheat protection mechanism. According to the method provided by the scheme, after the temperature of the evaporator is detected to reach the set temperature, the rotating speed of the fan and the mode of the air guide plate are adjusted, so that hot air blown out by the air conditioner and indoor cold air can be better subjected to heat exchange, and the heating effect of the air conditioner can be improved to a certain extent. Then, the temperature of the evaporator is collected, and when the temperature reaches the set temperature, the overheat protection mechanism is started. The scheme provides an overheating protection control method capable of improving the thermal effect of the air modulation to a certain extent.
Fig. 3 is a flowchart illustrating a second control method for overheat protection of an air conditioner according to an embodiment of the present application. As shown in fig. 3, the control method of the air conditioner overheating protection may include the steps of:
Specifically, the principle and implementation of step 301 are similar to those of step 201, and are not described again.
Specifically, after step 301, step 302A may be executed, and step 302B may also be executed.
The preset maximum rotating speed is the maximum rotating speed of the fan preset according to actual conditions.
The first time is a time length value preset according to actual conditions.
Specifically, if it is determined that the first temperature is greater than or equal to the preset threshold and the first rotating speed is less than the preset maximum rotating speed of the fan, the rotating speed of the fan may be adjusted first, and the current first rotating speed of the fan is adjusted to the preset maximum rotating speed, so as to increase the air volume and strengthen the indoor air circulation. And acquiring a third temperature of the evaporator after the first time.
The second time is a time length value preset according to actual conditions.
Specifically, the third temperature of the evaporator is compared with a preset threshold, and if the third temperature is determined to be lower than the preset threshold, the rotating speed of the fan is adjusted from the preset maximum rotating speed to the original first rotating speed. Then, step 301 is continued.
Or if the third temperature is determined to be greater than or equal to the preset threshold value and the first mode is determined not to be the down-blowing mode, then adjusting the mode of the air deflector, and adjusting the mode of the air deflector from the current first mode to the down-blowing mode; thereby blowing the wind downward to enhance the indoor air circulation. And acquiring a fourth temperature of the evaporator after the second time elapses.
Specifically, the fourth temperature of the evaporator is compared with a preset threshold, and if the fourth temperature is determined to be lower than the preset threshold, the mode of the air deflector is restored from the lower blow-molding mode to the original first mode.
