(Embodiment 1)
FIG. 1 is a diagram showing a configuration of an air cleaner in an embodiment of the present invention. In FIG. 1, an air inlet 2 for sucking indoor air is provided in the air cleaner body 1, a filter 3 is provided as a cleaning means for purifying the air sucked from the air inlet, and a means for ventilating the filter 3 is provided. A fan 4 is provided, an exhaust port 5 for blowing out clean air is provided, a gas sensor 6 is provided as a means for detecting gas components in the air, and a dust sensor 7 is provided as a means for detecting particle components in the air. A display unit 8 for displaying the result, a microcomputer 9 for controlling the fan 4, the gas sensor 6 and the dust sensor 7 in response to the measurement result of dirt, and an automatic mode 10 for controlling the fan 4 according to the dirt level. Provide and configure.

  When the air is not dirty, energization of the fan 4 and the gas sensor 6 or the dust sensor 7 is stopped.

  FIG. 2 shows a flowchart of microcomputer control until the energization is stopped.

  The microcomputer 9 provides dirt levels for the gas sensor 6 and the dust sensor 7. When dirt is detected, each sensor determines the dirt level and cleans it. Then, when the air is cleaned, the sensor that has been detected immediately before the air is not contaminated is energized, and the energization of the other sensor is stopped.

  For example, the dirt level of the gas sensor 6 and the dust sensor 7 is set to level 0 when the dirt level of the gas sensor 6 and the dust sensor 7 are not dirty, and level 5 is set to the level of dirt most. Assume that the gas sensor 6 detects dirt and becomes level 3 during operation in the automatic mode, and the dust sensor 7 also detects dirt and reaches level 4. It is assumed that the air is cleaned and the dust sensor finally reaches level 0 and then the gas sensor reaches level 0. In that case, it is determined that there are more odor components than particle components in the current use environment, and the gas sensor continues to be energized and the dust sensor is de-energized. Further, when the air is not contaminated, the display unit 8 is turned off.

  The air purifier main body 1 configured as described above is installed indoors, and the fan 4 is stopped and one of the sensors is stopped, so that power consumption can be suppressed and dirt can be detected efficiently.

(Embodiment 2)
The present embodiment is different from the first embodiment only in the control method, and the same components are given the same reference numerals and detailed description thereof is omitted.

  FIG. 3 shows a microcomputer control flowchart until the predetermined time for stopping energization is changed.

  When the air is not dirty, that is, when the fan 4 is stopped and the energization of one sensor is stopped, the fan 4 is periodically operated and the energization of the sensor that has been de-energized is started. To do. The microcomputer 9 controls the time for stopping the fan 4 and the sensor.

  For example, here, if the state in which the fan 4 and the sensor are stopped continues for one hour, the fan 4 and the sensor that has been de-energized are energized, run for 15 minutes, and if no dirt is detected, either the fan 4 or If the sensor is stopped and dirt is detected, the operation according to the degree of dirt is started.

  If no fouling is detected after 15 minutes of operation, the fan is stopped and energization of one sensor is stopped, but the stop time is changed from 1 hour to 1 hour 20 minutes. When dirt is detected, after the air is cleaned, the time for stopping the fan 4 and one of the sensors is changed from 1 hour to 50 minutes.

  The air cleaner main body 1 configured as described above is installed indoors, and the power consumption can be suppressed by stopping the fan 4 and the sensor in accordance with the indoor dirty environment.

(Embodiment 3)

  When the air is not contaminated, that is, when the fan 4 is stopped and the energization of one sensor is stopped, the energization of the sensor that has been de-energized is started and the fan 4 is operated for a certain period of time. . The microcomputer 9 controls the time for energizing the fan 4 and the sensor.

  For example, if the state in which the fan 4 and the sensor are stopped continues for one hour, the fan 4 and the sensor that has been de-energized are energized, run for 30 minutes, and if no dirt is detected, either the fan 4 or If one sensor is stopped and dirt is detected, an operation corresponding to the degree of dirt is started. When dirt is not detected in the operation for 30 minutes, the one-hour fan 4 and one of the sensor operations are stopped, and the next operation time is changed to 30 minutes or 20 minutes. When the dirt is detected, after the air is cleaned, the one-hour fan 4 and the sensor operation are stopped, and the operation time is changed from 30 minutes to 40 minutes.

  For example, here, if the state in which the fan 4 and the sensor are stopped continues for 1 hour, the fan 4 is operated with the air volume 2 and the sensor that has been de-energized is energized and operated for 30 minutes. If no dirt is detected, either the fan 4 or one of the sensors is stopped. If dirt is detected, an operation corresponding to the degree of dirt is started. Here, the air volume is 0 to 5 steps, and the maximum air volume is 5.

  If no dirt is detected in the operation for 30 minutes, the one-hour fan 4 and one of the sensor operations are stopped, the air volume is changed from 2 to 1, and the operation is performed for 30 minutes. If dirt is detected, after the air is cleaned, the operation of the fan 4 or one of the sensors is stopped for 1 hour, the air volume is changed from 2 to 3, and the operation is continued for 30 minutes.

  The microcomputer control flowchart figure until it changes the sensor stopped by the dirt memorize | stored in FIG. 6 is shown.

  The contamination detected for a predetermined time by the microcomputer 9 is stored. For example, when the result of detecting dirt for 5 hours is stored here, the result detected by the gas sensor 6 and the dust sensor 7 for 5 hours is compared to determine the type of dirt that is often in the air. For example, if the gas sensor reaches 7 times in 5 hours and the dust sensor reaches 3 times in 5 hours, the microcomputer 9 determines that the dirt in the air has a lot of odor components and air. When the sensor is cleaned and the energization of the sensor is stopped, the gas sensor with a large detection result is energized and the dust sensor with a small detection result is stopped.
