Description

A airconditioner auto cleaning system and method

The present invention relates to an automatic purifying system and method of an air conditioner, and more particularly, attaching a pollution detection sensor to an air conditioner, and detecting pollutants, odors, and moisture suspended in air through the pollution detection sensor, according to the degree of pollution. The present invention relates to a system and a method for automatically purifying an air conditioner in which an air purifier is automatically operated without a user's key input.

An air conditioner is an apparatus for keeping a room in a comfortable state and is also called a cooling device. An air conditioner controls the temperature, humidity, and airflow distribution suitable for human activities in a certain space (home, office, or workplace), and at the same time, removes dust floating in the air.

Conventional air purifiers have an input unit for controlling the operation of the air conditioner and the operation of the air conditioner through key input according to a user's selection, and electrical characteristics such as pollutants, odors, and moisture suspended in the air by the selection of the input unit. An electrostatic precipitator to purify using; It is composed of a microcomputer for controlling the electrical properties of the electrostatic precipitator and at the same time detects a signal input through the input unit to perform a corresponding function.

Referring to the operation of the conventional air purifier configured as described above with reference to the flow chart shown in FIG.

In the first step, power is supplied to the air conditioner to start the operation of the air conditioner. In the second step, it is determined whether the user presses the operation button of the air conditioner through key input at the same time as the operation of the air conditioner. See S11 and S12)

If the determination result of the second step S12 is affirmative, operation of the air purifier is performed in the third step, and if the determination result of the second step S12 is negative, the process returns to the first step S11. (See S13).

Since the operation of the air purifier is in progress, it is determined whether the stop button of the air purifier is pressed in the fourth step, and if the determination result of the fourth step is affirmative, the operation of the purifier is stopped in the fifth step and the determination result of the fourth step If is negative, the process returns to the third step S13 (see S14 and S15).

However, since the conventional air purifier is operated in such a way that the microcomputer receives the input by a key press operation by the user's selection and processes the input items, there is a problem in that the air purifier is operated by the subjective judgment of the user.

The present invention has been made in order to solve the above problems of the prior art, the object is to attach a pollution detection sensor to the air conditioner and to detect the pollutants, odors, moisture suspended in the air through the pollution detection sensor and its pollution The present invention provides an automatic purifying system and method for an air conditioner in which an air purifier is automatically operated without a user's key input.

1: Pollution Detection Sensor 2: Microcomputer

3: electric dust collector

According to a first aspect of the automatic purifying system for an air conditioner according to the present invention for solving the above problems, a pollution detection sensor for automatically detecting a pollution element floating in the air during operation of the air conditioner and applying a decontamination signal; When the decontamination signal of the contamination detection sensor is transmitted, the microcomputer generates a drive control signal instructing to turn on / off the air purification function to remove the pollutant, and the power is supplied by the drive control signal of the microcomputer to prevent the contamination. And an electrostatic precipitator which performs a function of collecting and purifying pollutants by the decontamination signal of the detection sensor.

According to a feature of the automatic purifying method of the air conditioner of the present invention, a first step of setting and determining the highest / lowest pollution level of air in order to instruct on / off of the air purifying function during operation of the air conditioner and floating during operation Monitoring the current contaminants and detecting that the air purifier is turned on when it is detected that the air pollutant is at the highest level; and when the air purifier of the second stage is reached, the level of pollution is reached. The third step is to turn off the purifying function of the air purifier.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a block diagram showing the configuration of the automatic purifying system of the air conditioner according to the present invention, referring to the pollution detection sensor for applying a decontamination signal by automatically detecting the contaminated elements in the air during operation of the air conditioner (1) and a microcomputer (2) for generating a drive control signal instructing to turn on / off the air purifying function to remove the contaminant when the decontamination signal of the contamination detection sensor (1) is transmitted, and the pollution detection It comprises an electrostatic precipitator (3) that performs the function of collecting and purifying pollutants, odors, and moisture detected by the pollution detection sensor (1) using electrical properties.

The electrostatic precipitator 3 is supplied with power by a drive control signal of the microcomputer 2 to perform a function of collecting and purifying pollutants by the decontamination signal of the contamination detection sensor 1.

The operation of the present invention configured as described above will be described with reference to the flowchart shown in FIG. 3.

In the first step, power is supplied to the air conditioner to start the operation of the air conditioner. In the second step, the microcomputer (2) is set in advance by setting the highest and lowest pollution values, which are the criteria for determining when to start and stop the operation of the air conditioner. (See S21 and S22).

In the third step, the pollution detection sensor 1 is started to operate to detect pollutants, odors, moisture, etc. suspended in the air, and in the fourth step, the pollution degree of air pollution in the pollution detection sensor 1 is determined by the second step. The monitor judges whether the maximum value set in S22 has been reached (see S23 and S24).

If the determination result of the fourth step S24 is negative, the process returns to the first step S21. If the determination result of the fourth step S24 is affirmative, in the fifth step, air is controlled through the control of the microcomputer 2. Purifier operation starts (see S25).

In the sixth step, the contamination detection sensor 1 determines whether the pollution value in the air according to the operation of the air purifier of the fifth step S25 reaches the minimum value set in the second step S22. Reference)

If the determination result of the sixth step (S26) is negative, the process returns to the fifth step (S25) and the operation of the air purifier continues, and if the determination result of the sixth step (S26) is positive, the air in the seventh step The purifier stops running (see S27).

In the eighth step, it is determined whether the stop signal of the air conditioner is detected. If the determination result of the eighth step is negative, the process returns to the first step S21 to continue the operation of the air conditioner and the determination of the eighth step. If the result is positive, the operation of the air conditioner is terminated in the ninth step (see S28 and S29).

The automatic purification system and method of the air conditioner of the present invention configured as described above attaches a pollution detection sensor to an air conditioner, and detects pollutants, odors, and moisture suspended in the air through the pollution detection sensor, and thus the degree of pollution. Accordingly, since the air purifier is automatically operated without the user's key input, there is an effect that the air purifier can be operated and stopped based on objective judgment criteria that measure the pollution level in the air rather than the subjective judgment of the user.
