Title: Dehumidifier
Inventor: UCHIDA TSUTOMU
IPC: F24F1/02
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To enable a silent operation to be assured under a comfortable humidity in a dehumidifier in which air sucked by a blower fan is dehumidified and dry air is blown out by a method wherein a humidity sensor is arranged in an air blowing passage at a suction side and an amount of air of the air blower fan is changed over in response to a difference between a present humidity and a predetermined humidity. SOLUTION: When an operation switch is depressed, a blower fan 26 performs an enforced operation and at the same time a compressor starts to perform its operation, an evaporator 24 is cooled and a condenser 25 is heated. Then, water vapor in the air condensed to form dew in the evaporator 24 passes through a water receptor pan 23 and is collected at a water discharging tank 32. As the dehumidifying operation is continued and the humidity in a room is decreased down to a first predetermined value, the blower fan 26 is changed over to a weak air blowing operation and further as the dehumidifying operation is promoted to cause the humidity to be decreased down to a second predetermined value, the blowing fan 26 is kept as it is and the compressor is stopped in its operation.  As the humidity is started to increase gradually, the compressor is started to operate and at the same time the blowing fan 26 is changed over to a strong air blowing operation. The humidity is kept comfortable through this repetitive operation as described above.

IPC: G03B7/28
Filed: 1980-08-28
Abstract: PURPOSE:To make exposure control with photodetectors not attaining the photometric threshold yet by changing over shutter speed priority to prescribed aperture priority mode when the photodetector for monitoring the aperture control out of plural photodetectors attains the photometric threshold. CONSTITUTION:Multiphotometry is accomplished by plural photoconductors PD2... including a photodetector PD1 for monitoring aperture control in the central part, and an aperture controlling circuit 10 is controlled by a comparator 8 and the like. The aperture is controlled in such a way that the exposure of the shutter speed of an arithmetic circuit 11 corresponding to the information having been set in a setting circuit 4 is attained, whereby the exposure is controlled with a shutter speed priority mode. When the photoelectric power output of this element PD1 attains a lower limit value, the output of a photometric threshold circuit 14 inverts to a low level to close an AND gate 18, and the aperture is held at full aperture by the circuit 10. At the same time, the shutter second time is operated by an erasing circuit 16 and the circuit 11, and the exposure is controlled with an aperture priority mode. The same holds true when the upper limit photometric threshold is attained. The exposure control takes place as far as there are the photodetectors which do not attain the threshold yet.
