Automatic air volume control method of air purifier

Since this is an open matter, no full text was included.

1 is an automatic air flow control control circuit diagram of an air purifier according to the present invention.

2 (a) to (c) are characteristic charts of a general gas sensor.

3 is a pollution degree according to the present invention and the output value table accordingly.

Claims (4)

Initial warm-up of the gas sensor 2-1 in the automatic air volume control of the air cleaner to automatically control the air volume by driving the fan motor 9 step by step according to the pollution degree detection value of the gas sensor (2-1) set pollution level detection value which is input after a time (to) has passed a reference value (D _X), sets the reference value (D _X) step 1, the variation of the degree of contamination is applicable (ΔV), the predetermined time for contamination compared (t1) when reading the contamination level detection value which is input after the lapse (D _a) be the same as the reference value (D _X) and Comparative (da-D _X) to the reference value (D _X) and NOF an initial reference value (D _X), When the reference value D _X is large (Da <D _X ), the present value Da is reset to the reference value D _X ((Da → D _X ), and the present value Da is the base value D _X) is greater than the difference in comparison to the above step 1 variation (ΔV) is changed to show contamination and flow rate accordingly, depending on the pollution level river, approximately selection Reference, _(X D) for resetting (D _X D _X → -ΔV), (DX + ΔV _X → D), and by the control of the current value detected current value is detected, a constant value after contamination has passed a predetermined time (t2) ( When a volunteer DC), this reference value (D _X) to reset (DC → _X D) by automatic flow rate control method of the air cleaner characterized in that to the air flow automatically controlled according to the pollution level detected value. The one-step change width (ΔV) according to the pollution degree is divided by each step by dividing the total change (0-5 [V]) of the detected values of the gas sensor 2-1 into predetermined steps D1-Dn. Are classified into pollution degree (a, b, c ... E, F), and the one-stage change range (ΔV) at each pollution degree is set in the table so that the reference value (D _X ) Automatic air flow control method of the air purifier, characterized in that to read the first step change range (ΔV). The method of claim 1, wherein, when the reference value (D _X) set after the current value (Da) are read a predetermined time (t1) has passed after is greater than the reference value (D _X), the difference is step 1 in the said reference value (D _X) If it is within the change range (ΔV) (Da-ΔV≤D _X ), it keeps and returns the current pollution degree indication and air volume, and if it is more than 1 step change range (Da-ΔV> D _X ), it displays the pollution degree and air flow 1 step the control and phase variation over (Da-3ΔV> D _X) is controls the contamination indication, and the air volume control to step 3, above step 3 variation (Da-3ΔV> D _X) is 3 to contamination indication and the air volume adjusting step 2 Automatic air volume control method of the air cleaner, characterized in that to control. The method according to claim 1, wherein after the selection of the after-cleaning is selected, the present pollution degree detection value Da is stored, and the pollution degree detection value D6 and the stored detection value Da after a predetermined time t5 are stored. In comparison (D6-Da), when the stored detection value Da is large (Db <Da), the operation stops, and when the stored detection value Da is small (Db≥Da), the operation is extended for a predetermined time t6 and then controlled to stop operation. Automatic air volume control method of the air purifier, characterized in that. ※ Note: The disclosure is based on the original application.
