Problems solved by technology

[0005] However, the existing method of judging the filter replacement timing of the air purifier by calculating the driving time of the fan motor sometimes does not match the actual state of the filter being polluted by dust.
That is, if it is used in a place with a clean surrounding environment, the filter will still be clean even if the fan motor is driven for a lon

Embodiment Construction

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is an exploded schematic diagram of an air purifier provided according to the present invention.

[0022] As shown in Fig. 1, the air purifier provided by the present invention has a main body 10 with an open front end, and the open front end of the main body is combined with a front panel 11 to form a box-shaped appearance, and the front panel 11 has a plurality of long lengths along the horizontal direction. A strip-shaped suction port 12 through which indoor air flows into the interior of the main body 10 .

[0023] The rear of the front panel 11 is provided with a detachable plate-shaped pre-filter 13 installed on the main body 10. The pre-filter 13 is used to filter larger particles contained in the air sucked from the suction port 12, such as condensed dust and fluff. and other impurities.

[0024] The rear of the pre-filter 13 is provided with ...

Abstract

The present invention relates to an apparatus for displaying filter exchange time of air cleaner and method thereof, the invention is to estimate practice degree of dust accumulated on the filter according to load state of fan motor, thereby more accurate filter exchange time is achieved. Therefore, the invention provides an apparatus for displaying filter exchange time of air cleaner, the air cleaner has a filter for eliminating dust and peculiar smell in the air, and a fan motor for driving air through said filter, the displaying device comprises a current monitor unit for measuring load current through the said fan motor; a control unit for comparing measured current value and predetermined reference current value, when the measured current value is less than reference current value, control signal for displaying said filter exchange time is output.

Description

technical field [0001] The present invention relates to an air purifier filter replacement timing prompting device and method thereof, in particular to an air purifier filter replacement timing reminder for prompting the filter replacement timing by accurately monitoring the degree of dust accumulation on the filter inside the air purifier Apparatus and method thereof. Background technique [0002] Generally speaking, an air purifier is a device for removing dust, bacteria, and peculiar smell in the air to purify the air. With the operation of the exhaust fan for circulating air, the dust, peculiar smell, etc. contained in the sucked indoor air are filtered while passing through a plurality of filters, and then the purified air is exhausted into the room again to purify the indoor air. [0003] Therefore, with long-term use, dust and other pollutants will accumulate on the filter inside the air purifier and eventually cause the filter to be blocked. In this regard, Korean L...
