LEDs 24 and 25 that light up in green are provided corresponding to the character display lamps 24 and 25, respectively. FIG. 4 is an illustrative view for explaining a change in display in the air pollution monitor area 12. The feature of this embodiment is that, as shown in FIG. 4, the display contents of the air pollution monitor area 12 are dynamically changed in accordance with the operation of the air purifier 1.

A more specific description will be given with reference to FIG.
The display mode of the air pollution monitor area 12 can be switched between a state in which the display is moving and a state in which the display is stopped by a signal from the display mode button 41 (see FIG. 3). In the state where the display is moving, the display state dynamically changes from the display on the left side to the display on the right side, and after the display at the right end, the display dynamically changes again from the display at the left end.

The display contents change from the upper display to the lower display depending on whether the air in the room is clean or the air is dirty. Whether the air is clean or the air is dirty is determined by the microcomputer 40 based on the detection signal of the air dirt detection sensor 9 described above, and which of the four-stage display shown in FIG. 4 is displayed according to the degree of air dirt. Or select.

First, when the air in the room is the most polluted, all the indicator lamp rows 21, 22, and 23 are illuminated in red. The lighting sequence is as follows. First, the leftmost indicator light column 21 consisting of four indicator lights is illuminated in red, then the central indicator light column 22 consisting of three indicator lights is illuminated in red, and then the right two indicators. The indicator light row 23 including lights is turned on in red. While the lighting of the three indicator lamp rows 21, 22, 23 is switched, the character indicator lamp 25 in a mode in which the mouth at the right end is opened is lit in green. Then, after that, the character display lamp 24 on the left side in the mode in which the mouth is closed is turned on in green.

The change in the dynamic display mode of the display columns 21, 22, 23 and the character display lamps 24, 25 indicates to the user that dirty air (red display lamp) causes an air purifier (character display lamp with open mouth). Impress the person being sucked into 25) in an easy-to-understand manner. Further, by lighting the character display lamp 24 with the mouth closed, the image of the air purifier 1 sucking in dirty air and purifying the air is given to the user.

More specifically, from the leftmost indicator lamp row 21 farthest from the character indicator lamp 25, the indicator lamp row lit toward the right changes in order. The change in lighting of the display lamp array indicates the direction in which the air purifier 1 (character display lamp 25) sucks air. Therefore, the air in the room is sucked into the character display lamp 25 which is similar to the image of the air purifier 1. It is possible to inform the user of the progress of the operation in an easy-to-understand manner.

Furthermore, the number of indicator lights in the indicator lamp array 21 far from the character indicator lamp 25 is large, and the number of indicator lamps is smaller as it is closer to the indicator lamp array 23. This represents that the air in the entire room is sucked toward the air purifier 1. Therefore, this indicator light row 21, 22,
The display change of 23 allows the user to visually realize that the air in the room is evenly sucked into the air purifier 1 and the sucked air is purified.

Next, in a state where the air in the room has been slightly purified, the display mode changes as in the second row from the bottom in FIG. That is, in the state where the character display lamp 25 with the rightmost mouth opened is turned on, the leftmost display lamp row 21 made up of four display lamps is turned on in green, and the next turned on indicator lamp row is. 22 and the indicator light array 22 is illuminated in red. Further, the indicator light row that lights up is switched,
The indicator light row 23 is illuminated in red. Then, all the indicator lights are turned off and the character indicator lights 2 with their mouths closed are displayed.
Only 4 is illuminated. Then, the manner of lighting is dynamically repeated from the beginning.

When the indicator lamp rows 21, 22, and 23 are sequentially switched on and turned on, when the indicator lamp row 21 farthest from the character indicator lamp 25 is turned on in green, the air purifier 1 slightly purifies the air in the room. You can let us know how you came. The user visually confirms that the air in the room is gradually purified by the air purifier 1 by changing the lighting color of the indicator light column 21 from red to green in the dynamic change of the display. can do.

When the air in the room is further cleaned, the lighting color of the indicator lamp row 21 and the indicator lamp row 22 becomes green and only the lighting color of the indicator lamp row 23 changes in the same dynamic display change as described above. It will be red. Furthermore, when the air in the room is sufficiently clean, in the above dynamic display change,
The lighting colors of the respective indicator lamp rows 21, 22, 23 are all made green.

As described above, the display lamp arrays 21, 22, 23
By changing the lighting color of from red to green, the user can
You can visually confirm that the air in the room has been purified. In addition, in a series of display modes, since the lighting color of the indicator light row can be dynamically switched according to the degree of contamination of air,
The user can confirm that the air purifier is functioning normally.

Further, in this embodiment, the speed of the dynamic change of the display mode is made proportional to the air volume generated by the blower fan 34 (see FIG. 3). That is, when the blower fan 44 generates a relatively large air volume, and when the intake air volume and the exhaust air volume of the air purifier 1 are large, the display change is relatively fast. Further, when the air volume by the blower fan 44 is small, the display is switched relatively slowly. Therefore, the user sees how the display changes (speed) and whether the air purifier 1 is functioning with a large air volume or a small air volume, that is, the dust collecting force of the air purifier 1 is strong. You can check

When the display state of the air pollution monitor area 12 is stopped by the display mode button 41, one of the indicator lamp rows 21, 22 and 23 is turned on in red and the character indicator lamp in the mode in which the mouth is opened is displayed. In the display mode in which 25 is turned on, or when the air is clean, only the character display lamp 24 in the mode in which the mouth is closed is turned on.

The display device can be modified as follows. That is, in the state where the display of FIG. 4 is moving, the indicator lamp rows 21, 22, and 23 are changed so that the cleaner the air is, the more the indicator lamp rows farther from the character indicator lamp 25 are lit green. On the contrary, the display lamp row close to the character display lamp 25 may be changed to light up in green.

Further, in the above-mentioned embodiment, the number of the indicator lamps is three, and the number of indicator lamps constituting each indicator lamp row is 4, 3, 2, 2.
An example is shown. However, the indicator lamp row is not limited to such an indicator lamp row, and for example, all the indicator lamp rows may be configured by the same number of indicator lamps. Further, instead of the plurality of indicator lamp rows 21, 22, 23, a plurality of one indicator lamps may be laterally arranged so as to represent the flow of air.

In the above-described embodiment, each of the indicator lamp arrays 21 and 2 is used.
Although it has been described that the LEDs 2 and 23 and the character display lamps 24 and 25 are turned on / off, the lamps may be used instead of the LEDs. Further, in the above-described embodiment, the air purifier of the type in which the dust is captured by the roll filter is taken up, but the dust of the type in which the dust is captured by the electrically charged dust collecting electrode plate It goes without saying that the display device of the present invention can also be applied to a cleaner.

The embodiment described above is a specific example of the present invention, and the present invention is not limited to such a specific example, and various different specific examples are made according to the contents of the claims. be able to.
