摘要： PURPOSE:To clean air in a room by detecting rapid rising of output of a gas sensor and operating an electric blower at maximum blowing capacity in a prescribed period. CONSTITUTION:An output of a gas sensor 13 is stored as a reference value and the rotating speed of an electric blower 2 is controlled depending on the difference between the reference value and an output value of the gas sensor 12 corresponding to the atmospheric condition. In the case the output of the gas sensor 12 rises rapidly, the electric blower is operated the maximum blowing capacity in a prescribed period. As a result, air in a room is cleaned rapidly and performance of the apparatus is thus improved remarkably.

摘要： PURPOSE:To inhibit the dispersion of the ON-timing of load minimally by starting charging with a delay of a fixed time from a zero cross point. CONSTITUTION:A zero cross detecting means 1 detects the zero cross point of a commercial power supply 9, and outputs pulses. A control means 4 starts the operation of a timer means 2 when pulses are output from the zero cross detecting means 1, and sets a reference voltage 5 corresponding to the controlled variable of a load when the timing the completed. A charging means 3 is reset simultaneously. A comparison means 6 outputs a signal when the charging voltage of a charging means 3 exceeds the reference voltage 5. A load control means 7 turns a load 8 ON when the signal is output from the comparison means 6. Accordingly, the dispersion of the ON-timing of a load can be reduced.

摘要： PURPOSE:To efficiently purify air by a method wherein the saturation of the output of a gas sensor is detected and a reference value is raised at every predetermined time from a staturation time to make the rising width of the reference value smaller than a saturation value and the intensity of a blower is determined on the basis of the difference between said output and the reference value. CONSTITUTION:The contamination of a room is detected by a gas sensor 12 and the output thereof is sent to a control circuit through a detection circuit 16 and, at the point of time when the output is judged to be saturated, a reference value is raised at every predetermined time and the rising width of said reference value is made smaller than a saturation value and argorithm determining the intensity of an electromotive blower 2 on the basis of the difference between the output of the sensor and the reference value is incorporated. When the output of the gas sensor 12 reaches a definite value or more, the number of rotations of the blower 2 can be also controlled on the basis of the absolute value output of the sensor.

摘要： PURPOSE: To make it possible to perform a control with a strong power when a power nozzle is turned on, by connecting photo-coupler in series to a motor, changing over the amplified signal of a magnetic sensing element into its divided signal or vice versa using the output of the photo-coupler, and varying the level of the power control. CONSTITUTION: When an at-hand switch 31 is shortcircuited, current flows in a motor 70 of a power nozzle 73, and a potential is generated at the two ends of a resistance 33, and a current flows in a photo-coupler 36 and another photo-coupler 37 is turned on. The potential of a capacitor 38 rises, and a transistor 39 is turned on. The collector of the transistor 39 is put at Low level, and the input terminal E of a switcher 45 is put at Low level. In actuation of the switcher 45, the input to a difference sensing circuit 50 becomes the potential at Z1 and X1 , and because the potential at Z1 lies at a point decided by dividing X1 and Z1 by resistances 26 and 27, it is naturally conditioned so that X1 -Zo > X1 -Z1 , and the input difference to the difference sensing curcuit lessens, to result in enlargement of the power of a motor-driven blower concerned 53. Thus a strong power of blower can be available by turning on the power nozzle.

摘要： PURPOSE: To perform proper power control of a blower by amplifying the output from a magnetic sensing element installed opposing to a magnet of a valve element using two steps of differential amplifiers, and changing over the signal due to a variable resistor into the amplified signal of the magnetic sensing element and vice versa. CONSTITUTION: The valve element 40 having a magnet 41 fitted to it is installed in an air flow path in a motor-drive blower 53, and a magnetic sensing element 42 is installed opposing to the magnetic 41. When the valve body 40 is shut and the distance between the magnet 41 and sensor elements 42 becomes the shortest, the output of the sensor element 42 maximizes, and the potential difference between the point A and reference point D becomes maximum owing to differential amplification of the first stage amplifier 12. If at this time, a variable resistor 15 is adjusted to make the potential at the point B equal to the point A, the input to the next stage amplifier 21 becomes equal, so that the output X1 becomes equal to the potential at the reference point Y1, and the power of the blower 53 decided by a difference sensing circuit 50 and a phase control circuit 51 becomes maximum. In case, for example a carpet, etc., is to be cleaned, therefore, a strong power of blower 53 can be available when an at-hand switch 31 is changed over by a switcher 45 to turn on the power nozzle.

摘要： PURPOSE:To enable the practical operation of the title cleaner with high profitability by carrying out the automatic operation in the operational patterns following a combination of plural set air volumes based on the output of a gas sensor in a control circuit, and appropriately controlling the operation in accordance with the progress in the contamination of air. CONSTITUTION:The cleaner is automatically operated by the control circuit 16 based on the output of the gas sensor 12 for detecting the air contamination degree in a room in the operational patterns following a combination of plural set air volumes. Namely, plural set levels determined by adding a specified value to the set reference level are set in the control circuit 16. When the air contamination degree progress, the cleaner is operated in the operational pattern following the preset air volume whenever the output of the gas sensor 12 exceeds the set level. When the air contamination degree decreases, the operation is continued without changing the operational pattern in the predetermined pattern even when the output exceeds the set level except when the output exceeds the maximum set level, and the operation is stopped after a specified time.

摘要： PURPOSE:To minimize the malfunctions of the title cleaner by detecting the change in the output of a gas sensor to discriminate even the case when a main body functions by the breathing of a user upon the gas sensor from the case when the main body functions due to the contamination of air. CONSTITUTION:The gas sensor 26 for detecting the degree of the contamination in a room and a control circuit 28 for automatically operating the main body in accordance with the output of the gas sensor 26 are provided. When the output of the gas sensor 26 exceeds the set reference level plus a specified value, the operation of the main body is started by a timer means 30, and time counting is started when the output of the gas sensor 26 again decreases lower than the reference level. Furthermore, whether the operation of the main body is continued or not when a specified time is counted by the timer means 30 is determined by the output of the gas sensor 26 in a judging means 34. As a result, an air cleaner hardly malfunctioning can be obtained.
