Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem associated with an air cleaner for cleaning indoor air, that an operating time necessary for cleaning indoor air is unknown and is hence desired to be notified although the state of the present uncleanness of the indoor air is recognized thereby. <P>SOLUTION: The air cleaner includes an odor detection means 7 for detecting odor components present in an indoor ambience, a dust detection means 6 for detecting dust, an uncleanness-level determining means 12 for determining the level of the uncleanness of an object to be detected based on output from the detection means 6, 7, an uncleanness-level memorizing means 13 for memorizing the levels of the uncleanness in time sequence determined by the uncleanness-level determining means 12, and an operating time display 8 as a display means for estimating and displaying a remaining operating time necessary for the cleaning based on the uncleanness levels in time sequence memorized in the uncleanness-level memorizing means 13. Thus, the amount of indoor dirt can be pre-estimated by memorizing the amount of indoor dirt generated in time sequence, and the time necessary for the cleaning based on the current air flow rate can be calculated and displayed. <P>COPYRIGHT: (C)2010,JPO&INPIT

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1 to 5, the main body 1 of the air cleaner is formed in a substantially box shape, a front panel is provided on the front surface of the main body 1, and an air inlet 2 is formed on the entire side surface of the main body 1. A filter 3 for purifying air and a fan motor 4 for passing air through the filter 3 are provided in the main body 1, and a blower outlet 5 is provided on the top surface of the main body 1. By driving the fan motor 4, air is sucked from the air inlet 2, cleaned through the filter 3, and then blown out from the air outlet 5.

  A dust detection means 6 having an optical dust sensor 6a as a dirt detection means is provided on the side surface of the main body 1 as a detection means for detecting air dirt, and a gas sensor is provided on the upper surface of the main body 1 as a detection means for detecting air dirt. An odor detecting means 7 having 7a is provided.

  Further, an operation time display unit 8 provided as a display means for displaying the operation time and an operation unit 10 having a dirt display unit 9 for displaying the air dirt level by color change are provided on the front upper portion of the main body 1 and are controlled. Part 11 is provided.

  The control unit 11 stores the level determination unit 12 that determines the output signal corresponding to the contamination detected by the detection unit to a contamination level of 0 to 5, and the contamination level determined by the level determination unit 12 in time series. Level storage means 13 is provided.

  In the above configuration, when the power supply is energized, the control unit 11 receives the output signal detected by the dust detection unit 6 or the odor detection unit 7 and performs a process of converting the level determination unit 12 to a dirt level value of 0 to 5. The level storage means 13 stores the time series.

  When the operation unit 10 is set to automatic operation, the control unit 11 operates the fan motor 4 according to the current dirt level value. At this time, the amount of air blown by the fan motor 4 with respect to the dirt level detected by the dust detection means 6 or the odor detection means 7 has the relationship shown in FIG.

  Further, the control unit 11 calculates the contamination level value of the dust detection unit 6 or the contamination level value of the odor detection unit 7 stored in time series from the contamination level value and the operating air flow shown in FIG. The determined predicted operation time is displayed on the operation time display unit 8 to inform the operation time until the end of purification. Thereafter, as the dirt level value increases or decreases, the predicted operation time for the dirt level value shown in FIG. 5 is changed, and the operation time display is continued until the end of purification. Further, even when the operation air volume is changed during the operation, the change is displayed and notified at the predicted operation time determined from the dirt level value and the operation air volume shown in FIG. Here, the predicted operation time determined by each operation air volume is determined according to the ratio of the operation air volumes.

  As described above, when the level of dirt generated in the room becomes constant, the purification end time is notified from the current operation air volume, so that the purification effect can be visually recognized and the usability can be improved.

  In addition, the predicted operation time is changed and displayed every time the operation air volume is switched, but the user can easily select the display by displaying the predicted purification completion time for all the operation air volumes at the same time. be able to.

  Further, as shown in FIG. 6, the predicted operation time for the dirt level value detected by the dust detection means 6 is further reduced as the operating air volume is smaller than the predicted operation time for the dirt level value detected by the odor detection means 7. By extending the length, in the case of relatively heavy dirt such as dust, it is possible to effectively collect dust with a small air volume over time.

(Embodiment 2)
The present embodiment is different from the first embodiment only in the control method, and those having the same configuration are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 7 and 8, the operation unit 10 is provided with a human detection unit 13 for detecting infrared rays. When a person enters the room, the human detection unit 13 detects infrared rays emitted from the human body. A signal is sent to 11, and when no infrared ray is detected, no signal is sent. While a signal is output from the human detection unit 13 at this time, a person is present, so the predicted operation time is displayed on the operation time display unit 8 and the signal from the human detection unit 13 is not output. Since no person is present in the room, the predicted operation time is not displayed on the operation time display unit 8.

  As described above, the predicted operation time is displayed only while the user who cares about the operation time is in the room, so there is no inconvenience in user-friendliness, and the predicted operation time is turned off after the user leaves the room. Power can be saved.

  Further, it is possible to further improve the usability by calculating the amount of power used from the predicted operation time and the amount of operation air and displaying the amount of power used on the operation time display unit 8.

  Although the predicted operation time is displayed in the first embodiment and the second embodiment, the estimated operation time may be displayed by increasing or decreasing the number of LED lamps displayed or by color display.

  By displaying the operation time until purification for the amount of dirt to be detected, the time required to achieve the purpose of the air purifier is notified, so the arrival time to the set temperature during cooling and heating is displayed It can also be applied to air conditioner operation control.
