Description

Air conditioner protection operation method and air conditioner
Technical Field
The invention relates to the field of air conditioning equipment, in particular to an air conditioner protection operation method and an air conditioner.
Background
With the popularization of air conditioners, the air conditioners have entered every family and become indispensable household electrical appliances in people's lives.
However, the air outlet of the indoor unit of the existing air conditioner is not provided with a protective device such as a protective net, and the fan blade rotates very fast in the running process of the air conditioner, so that if a user cleans components such as an air duct and an air outlet of the air conditioner, or a user such as a child inserts fingers into the air inlet and the air outlet by mistake, the fan blade is easily damaged or damaged by the fan blade.
The present application is proposed to solve the above technical problems.
Disclosure of Invention
The invention designs an air conditioner protective operation method and an air conditioner, which aim to overcome the problem that a fan blade hurts a user or is damaged by foreign matters easily in the operation process of the conventional air conditioner.
In order to solve the problems, the invention discloses an air conditioner protection operation method, which comprises the following steps:
p1, starting the air conditioner to run;
p2, detecting the distance S between the foreign body and the air outlet;
p3, determining whether the value of S satisfies: s > a first preset threshold S1? If so, the air conditioner normally operates; if not, go on to step P4;
p4, determining whether the value of S satisfies: the first preset threshold S1 ≧ S > the second preset threshold S2? If so, reducing the opening angle of the left air deflector and the right air deflector; if not, go on to step P5;
p5, the opening angle of the upper and lower air deflectors is reduced, and the fan speed is reduced.
According to the method, the distance S between the foreign matters at the air outlet and the air outlet is detected in the starting state of the air conditioner, and different regulation measures are taken according to the value of S and the relative size between the first preset threshold value S1 and the second preset threshold value S2, so that on one hand, when the foreign matters are close to the air outlet, the air outlet can be closed in time, and the foreign matters are prevented from being inserted into the air outlet and damaging objects inserted into the air outlet and blades inside the air conditioner; on the other hand, the air conditioner can run as stably as possible on the premise of safety, and the frequency of sudden start and stop of the air conditioner is reduced.
Further, the method comprises the following steps:
p1, starting the air conditioner to run;
p2, detecting the distance S between the foreign body and the air outlet;
p3, judging whether the value of S continuously satisfies the following conditions within the time of t 1: s > a first preset threshold S1? If so, the air conditioner normally operates; if not, go on to step P4;
p4, judging whether the value of S continuously satisfies the following conditions within the time of t 2: the first preset threshold S1 ≧ S > the second preset threshold S2? If so, reducing the opening angle of the left air deflector and the right air deflector; if not, go on to step P5;
p5, judging whether the value of S continuously satisfies the following conditions within the time of t 3: s is less than or equal to a second preset threshold value S2, if yes, the opening angle of the upper air deflector and the lower air deflector and the rotating speed of the fan are reduced; if not, keeping the running state of the current air conditioner unchanged.
Through the limitation of t1, t2 and t3, the air conditioner is prevented from making corresponding protection actions when people or pets and the like near the air conditioner pass through the air conditioner transiently, the accuracy of the protection actions made by the air conditioner can be improved, and the stable operation of the air conditioner can be guaranteed.
Further, the value range of the first preset threshold S1 is 8-15 cm, the value range of the second preset threshold S2 is 3-7 cm, and the value range of t1 is 5-15S; the value range of t2 is 20-40 s; the value range of t3 is 10-30 s.
The accuracy of air conditioner protection can be improved and the regulation and control frequency can be reduced through optimizing the value ranges of the first preset threshold S1, the second preset threshold S2, the t1, the t2 and the t 3.
Further, in the step P4, if the value of S continuously satisfies: if the first preset threshold value S1 is larger than or equal to S and larger than the second preset threshold value S2, the left air deflector and the right air deflector are rotated to the leftmost side or the rightmost side of the air conditioner, and the opening angle of the left air deflector and the right air deflector is reduced to be zero or close to zero. During this time, the compressor and the fan of the air conditioner are normally operated. Therefore, the purpose of quickly shielding the air outlet can be realized through the rotation of the left air deflector and the right air deflector, and the foreign matters are prevented from being inserted into the air outlet when being further close to the air outlet.
Further, in the step P5, if the value of S continuously satisfies: and S is less than or equal to a second preset threshold value S2, the opening angle of the upper air deflector and the lower air deflector and the rotating speed of the fan are reduced according to the change of the distance S between the foreign matters and the air outlet.
And the accuracy and timeliness of the air conditioner protection action can be improved by reducing the opening angle of the upper air deflector and the lower air deflector and the rotating speed of the fan according to the change of the distance S between the foreign matter and the air outlet.
Further, when the value of the distance S between the foreign matter and the air outlet is reduced by 1cm, the opening angle of the upper air deflector and the lower air deflector is reduced by alpha until the upper air deflector and the lower air deflector are completely closed, wherein the value range of the alpha is 10-15 degrees.
The mode that the adjusting means of the opening angles of the upper and lower air deflectors is set to be reduced along with the reduction of the value of the distance S between the foreign matters and the air outlet can warn people at the accessories of the air outlet on one hand, and on the other hand, the upper and lower air deflectors cannot be suddenly closed, so that the running stability of the air conditioner is improved.
Further, when the value of the distance S between the foreign matter and the air outlet is reduced by 1cm, the rotating speed of an inner fan in the air conditioner is reduced by K1rpm, the rotating speed of an outer fan in the air conditioner is reduced by K2rpm until the inner fan, the outer fan or a compressor in the air conditioner stops running, wherein the value range of K1 is 100-300 rpm, and the value range of K2 is 50-200 rpm.
The adjusting means of the rotating speeds of the inner fan and the outer fan is set to be a mode of reducing along with the reduction of the value of the distance S between the foreign matter and the air outlet, on one hand, the inner fan and the outer fan can be prevented from being suddenly closed, the stability of the air conditioner in operation is improved, and the service life of the air conditioner is prolonged. On the other hand, the rotating speeds of the inner fan and the outer fan are matched with the air outlet area of the air outlet, and the adaptive capacity of the whole air conditioner in the operation process is improved.
Further, in the step P4, after the left and right air deflectors are rotated to the leftmost side or the rightmost side of the air conditioner, the value of the distance S between the foreign object and the outlet is continuously detected, and if the value of S continuously satisfies the following condition within the time t 1: s is larger than a first preset threshold value S1, the left air deflector and the right air deflector are restored to the initial positions; if the value of S is continuously satisfied for time t 3: and S is less than or equal to a second preset threshold value S2, the opening angle of the upper air deflector and the lower air deflector and the rotating speed of the fan are reduced.
In the protection operation process of the air conditioner, the protection state of the air conditioner can be updated in time by continuously detecting the value of the distance S between the foreign matter and the air outlet, so that the air conditioner can adapt to the change of the environment spontaneously.
Further, in the step P5, after the operation of the inner fan, the outer fan or the compressor in the air conditioner is stopped, the value of the distance S between the foreign object and the air outlet needs to be continuously detected, and if the value of S continuously satisfies the following condition within the time t 1: s is larger than a first preset threshold value S1, the air conditioner is recovered to be operated in an initial state, and if the value of S is continuously satisfied within the time t 2: and if the first preset threshold value S1 is more than or equal to S and more than a second preset threshold value S2, rotating the upper air deflector and the lower air deflector to the initial position, and simultaneously starting an inner fan, an outer fan and a compressor in the air conditioner to keep the states of the left air deflector and the right air deflector unchanged.
In the protection operation process of the air conditioner, the protection state of the air conditioner can be updated in time by continuously detecting the value of the distance S between the foreign matter and the air outlet, so that the air conditioner can adapt to the change of the environment spontaneously.
The air conditioner comprises an air outlet, wherein the air outlet is provided with an upper air deflector, a lower air deflector, a left air deflector, a right air deflector and a sensor, and the sensor can measure the distance S between a foreign body near the air outlet and the air outlet.
