摘要： PURPOSE:To suitably control the control timing by providing correcting means for response delay of a humidity sensor against the change of temperature in the set space of the humidity sensor, and preventing the absolute humidity signal and the dew point temperature signal from changing when only the temperature in the set space changes. CONSTITUTION:A humidity sensor 1 outputs the voltage Vr in response to the resistance value which changes corresponding to humidity conditions within a car room. On the other hand, a temperature sensor 4 is set on the surface of sensing the humidity of the sensor 1, and it detects the temperature changes of the sensor 1 itself to output the voltage Vt in response to the detected value. And relative humidity is determined by an operating means 5 form the voltages Vr, Vt, and a characteristic chart which is composed of the relative humidity using the temperature of the portion to be detected in humidity as a parameter and the resisting value of the humidity sensor is substituted to a characteristic chart which is composed of a voltage signal corresponding to the resistance value and relative humidity, and when relative humidity RHf is determined, the relative humidity represents relative humidity on the surface sensing the humidity of the temperature sensor. The absolute humidity and the dew point temperature are determined by operating the means 3 on the basis of a humidity-air diagram from the humidity RHf and the output Vt, and when signals KH, KT are outputted the humidity and the temperature within the car room are represented.

摘要： PURPOSE:To provide a water supply tank of a humidifier for an automobile having same effects even if freezing and thawing are repeated by ensuring the substantial capacity of the water supply tank to the maximum limit while preventing the water supply tank from breaking in freezing the humidifying water. CONSTITUTION:A water supply tank 1 is a double structure consisting of an inner shell 1d and outer shell 1c. The inner shell 1d is molded by expansible synthetic resin integrally with an opening part 1a molded with hard synthetic resin, and the outer shell 1c is molded with hard synthetic resin. The inner and outer shells 1d, 1c are spaced by a gap C from each other over the whole periphery and jointed with each other in the opening part 1a. Then, the volume of the inner shell 1d is set to not more than 0.9 times the volume of the outer shell 1c. Thus, since the inner shell is expanded or contracted according to a change in the volume of water frozen and thawed in the water supply tank, an effect of preventing the water supply tank from breakage is repetitively fulfilled.

摘要： PURPOSE:To sufficiently heat-exchange a liquid refrigerant with air to evaporate so as to prevent the outflow of the refrigerant by allowing a refrigerant to meander to flow toward the flow direction of air. CONSTITUTION:A liquid refrigerant allowed to flow in from an introduction pipe 8 is allowed to flow in first refrigerant passages 4-4c connected transversely and meander to flow in the direction shown by arrow marks in second refrigerant passages 6-6c a plurality of times to always become a counterflow to the flow of air. Accordingly, the refrigerant is allowed to meander to flow in the refrigerant passages 6-6c to evaporate and is gradually phase-changed from liquid to gas to increase a specific volume. Thereby the whole refrigerant is evaporated so as to prevent the outflow of the liquid refrigerant.

摘要： PURPOSE:To keep indoor humidity accurately in a comfortable condition and prevent moisture condensation on a window glass by providing a suction air temperature sensor and a fog temperature sensor in a duct and a glass temperature sensor on the inside surface of a window glass and comparing by calculation signals from those sensors to control as oscillation circuit. CONSTITUTION:Two sensors, a suction air temperature sensor 7 installed in the air channel where air at the downstream of a fan enclosed by the dot line A which does not contain fog is flowing and a fog temperature sensor 8 installed in the air channel where fog-containing air is flowing and which is enclosed by the dot line B are used as humidity detection sensors. The inside surface temperature of a window glass is detected by a glass temperature sensor 10 which is installed on the window glass 12 and by connecting the main body of a humidifier to the glass temperature sensor 10 with an extension cord 11. Output signals S1, S2, and S3 from the sucked air temperature sensor 7, fog temperature sensor 8, and glass temperature sensor 10 are inputted to a comparison calculator through a signal converter, and an oscillation circuit is controlled by the results of the calculation. With this arrangement the accuracy of the indoor humidity detection section, its response and durability can be improved.

摘要： PURPOSE:To make improvements in accuracy, responsiveness and durability, by covering the cab space side of a heat transfer member being made to stick fast to an inner surface of a car body with a heat insulating material but a part, setting an uncovered part down to a cloud generating surface, and installing a sensor there, while constituting it so as to predict a cloud with output of the sensor. CONSTITUTION:A heat transfer member 1 is attached, by suction, to a car body via the suction surface coated with a contact heat transfer accelerator 15 of silicone grease or the like. And, when temperature inside a car becomes lower than outside temperature and the specified temperature difference is produced, the part of temperature on a mirror 5 of the heat transfer member 1 becomes lower than that of inner surface of a windowpane, whereby a cloud appears on the mirror 5 of the heat transfer member 1 before the inner surface of the windowpane 12 is clouded. A light receiving part of a light detector 9 detects this cloudy state with a reflection factor variation in light, and transfers it to a discrimination device (unillustrated herein). This discriminating device discriminates the cloudy state from a signal to be inputted, commanding a cloud removal motion. Thus, accuracy and responsiveness are improved.

摘要： PURPOSE:To permit the use of the title structure for automobile, by a method wherein the main body of a humidifier is provided with a leaf spring and a feed water tank is provided with a spring receptor respectively so that the leaf spring is retained automatically to the spring receptor upon mounting the feed water tank, in the mounting structure of the title feed water tank of cartridge type. CONSTITUTION:When a feed water tank 1 is mounted to the main body case 5 of an ultrasonic humidifier orthogonally to the surface of paper, a spring receptor 2, having L-shape section, is engaged with the chevron type bent part of a leaf spring 5a and the leaf spring is fixed by the deflecting force thereof. The attaching and detaching forces of the leaf spring are determined by the angle of chevron shape bent part of the spring 5. a contact angle between the spring and the receptor 2 and the deflecting force of the leaf spring 5a. When water in the tank 1 freezes and floats up, the floatation is absorbed by the bent part whereby the fixed condition of the tank may be maintained. According to this constitution, the title structure may be mounted on an automobile and may cope with the freezing of water in the tank.

摘要： PURPOSE:To make it possible to cut off power supply to an oscillation circuit driving a vibrator and to prevent an electrode of the vibrator in contact with water being corroded in water and damaged by detecting the water by a water level detection circuit when the voltage of the detection electrode becomes below a difined value. CONSTITUTION:A detection voltage corresponding to a current flowing to a detection electrode 20 from an auxiliary electrode 19 in accordance with a level of water 9 by an detection electrode 20 provided at a water level detecting position of the water 9 within an atomizing tank 4 is inputted into a water level detection circuit 13, where by, when the voltage of the detection electrode 20 has reached a defined value, it is detected that the water level has been lowered, and the power supply to an oscilla tion circuit 8 is interrupted by the relay 15 of the water level detection circuit 13, and when the water level is restored, the power supply is again applied. When a power supply switch 12 is turned off, a current from a battery 6 is completely inter rupted because a normally open contact 16 is opened and a current to the detection electrode 20 from the auxiliary electrode 19 of the atomizing electrode 19 is also cut off. Therefore, the galvanic corrosion of the auxiliary electrode 19 is produced only when the power supply switch 12 is turned on, and the corrosion of the electrode 19 is reduced.
