Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Example 1
In preferred embodiment 1 of the present invention, there is provided an air conditioning control method which can be directly applied to various air conditioning units. In particular, fig. 1 shows an alternative flow chart of the method, which, as shown in fig. 1, comprises the following steps S102-S106:
s102: detecting the distance between a target object and a fan of an air conditioner;
s104: judging whether the distance meets a preset shutdown condition or not;
s106: if yes, controlling the fan to stop.
In the above-mentioned embodiment, through the distance between the fan that detects target object and air conditioner, control the fan and shut down when the distance satisfies preset shut down condition, it uses in relevant place to have solved among the prior art air conditioning unit, the amount of wind is too big when the user gets the thing, it is not good to directly blow to cause the travelling comfort to experience to the human body, and directly blow for a long time has the problem of frostbite injury to human skin, avoid the user to be directly blown near the fan, prevent frostbite, user's comfortable nature experience has been promoted.
Except for carrying out shutdown control on the fan, the effect of improving the comfort of a user can be realized by reducing the air outlet speed of the fan.
Before detecting the distance between the target object and the fan of the air conditioner, the method further comprises the following steps: monitoring whether the air conditioner enters a refrigeration mode; when the air conditioner enters a refrigeration mode, detecting whether a target object appears in a room where the air conditioner is located; and if the target object appears, triggering and detecting the distance between the target object and a fan of the air conditioner. The control to the fan prevents to directly blow to the human body when mainly used air conditioning unit refrigerates, can also avoid directly blowing to the human body when heating according to user's demand setting certainly, avoids directly blowing uncomfortable that hot-blast caused.
The target object at least comprises a human body; in addition to the human body, other objects such as pets can be included in the range of the target object.
Whether the target object appears in the room where the air conditioner is located or not is detected, and the method comprises the following steps: identifying whether a human body appears in a room through a human body identification sensor; if a human body is recognized, it is determined that a target object is present indoors.
In the above embodiment, the preset shutdown condition includes at least one of: the distance is smaller than the preset distance, and the change trend of the distance is smaller. And when the distance is less than the preset distance, the fan needs to be adjusted in time. When the variation trend of the distance is smaller, the fan can be adjusted in advance, and the problem that the distance between a user and the fan is close to meeting the shutdown condition before the distance is smaller than the preset distance can be solved, so that the fan is adjusted in advance.
After controlling the fan to shut down, still include: the opening degree of the electronic expansion valve is reduced, and the running frequency of the compressor is reduced. In addition, after controlling the fan to stop, the method further comprises the following steps: recording the shutdown time of the fan; and when the shutdown time exceeds the preset time, controlling the fan to restart. Through adjustment electron expansion valve opening etc. when shutting down, reduce the heat transfer volume, avoid outer machine to report the protection, and avoid interior fan to shut down and lead to the unit wrong report protection scheduling problem for a long time through the settlement time, and various states are not closed like the door when general user got the thing, cold volume runs off etc. and the stop mode of fan still is favorable to practicing thrift the electric energy.
According to the control scheme, when the unit enters a refrigeration mode, the distance sensor detects the distance between a human body and the fan in real time through the human body recognition sensor, the fan operates in a speed reduction mode until the fan stops operating in different set distances, the opening degree of the electronic expansion valve is synchronously reduced, the heat exchange quantity is reduced, unit false alarm protection is avoided, the operation time of the fan is recorded, the fan is restarted when the preset time is exceeded, the operation frequency of the compressor is reduced, and the false alarm fault of the external unit when the fan stops for a long time is avoided. The bad experience of people when the fan annex gets the thing is reached, prevents frostbite etc.. By adopting the control method and the application of the invention, the problems that when the existing unit is applied to relevant places to take objects, the experience effect of directly blowing the objects to people is not good due to overlarge air volume, and the skin of a human body can be frostbitten for a long time are solved.
Another air conditioner control method is further provided in preferred embodiment 1 of the present invention, specifically, fig. 2 shows an alternative flowchart of the method, and as shown in fig. 2, the method includes the following steps S202 to S206:
s202: the distance between the human body and the fan is identified through a human body sensor and a distance sensor;
s204: determining a control instruction of the fan according to the distance, controlling the fan to stop running, synchronously controlling the flow of the electronic expansion valve, adjusting the running frequency of the compressor, and recording the stop time of the fan;
s206: and controlling the start and stop of the fan according to the stop time.
Specifically, when the fan is applied to with commodity circulation and the relevant place of giving birth to the bright (excellent bright, give birth to bright express delivery, freezer etc.) every day, because relevant personnel need get into the freezer and frequently get the goods, and relevant goods are closer apart from the fan, the fan directly blows very cold to the people when getting goods in annex and dead ahead. The controller is additionally arranged in the unit, the position sensor and the human body recognition sensor are additionally arranged, and when the distance sensor detects that the distance between a human body and the fan is less than 3 meters, the unit gives an instruction to stop running the fan. And synchronously transmitting a signal to the external unit to turn down the electronic expansion valve, reducing the running frequency of the compressor, reducing the heat exchange quantity and recording the stop time of the fan. When the stop time of the fan exceeds 3min (generally, the time for taking goods is short, and personnel are familiar with relevant positions, and the time can be adjusted according to the system and actual conditions), the fan is restarted, the opening degree of an electronic expansion valve of an outer machine is increased, the frequency of a compressor is increased, and the condition that the fan is stopped for a long time to cause the failure reporting protection of a unit to stop is avoided. And when the distance between the human body and the fan is detected to exceed 3 meters, starting the fan and executing the original command.
In the above-mentioned embodiment, through the distance between the fan that detects target object and air conditioner, control the fan and shut down when the distance satisfies preset shut down condition, it uses in relevant place to have solved among the prior art air conditioning unit, the amount of wind is too big when the user gets the thing, it is not good to directly blow to cause the travelling comfort to experience to the human body, and directly blow for a long time has the problem of frostbite injury to human skin, avoid the user to be directly blown near the fan, prevent frostbite, user's comfortable nature experience has been promoted.
Example 2
