Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the material of the detection part in a hygrometer used to measure air humidity such as humidity, and to a hygrometer that whitens the switch element of an electric circuit. It is used for humidity measurement and humidity control in air conditioning systems and air cleaning equipment in each home.

[Prior art] The hygrometer and the detection part were also front-mounted with glass, which had drawbacks such as being easily damaged. Furthermore, since the display was based on the swelling of a liquid such as alcohol, it was difficult to connect it to an electric circuit and it was difficult to control it electromechanically. On the other hand, in electric circuits, due to the use of bimetals, etc., switches that open and close based on temperature differences, which constitute switching elements, have not been able to be controlled in minute units. As a high-performance device, a thermocouple wire type meter that uses a thermocouple wire to detect minute temperature changes and controls the temperature by applying the flow of electrons in the detection section is expensive.

[The problem to be solved by the invention 2] This invention theoretically requires that a humidity measuring device be attached to the temperature measuring device and the scale be changed to humidity, but the detection part of the hygrometer is It uses a shape memory alloy, and takes advantage of the smooth reaction of the alloy to control humidity changes. This hygrometer has an electric circuit that uses a superconducting thermocouple wire type thermostat for precise humidity changes.

[Means for Solving the Problems] The present invention will be explained based on the drawings. In FIG. 1, there is a knob error of about 10° C. below the panel of the outer box 1 of the temperature meter, and the temperature is set. The scale 3 where the upper pointer is visible is the correction temperature unit for the lower set temperature. As shown in FIG. 2, the movable part of the pointer 7 is a rotational moment driven by the rotational torque of a motor. Knob 4
There is a scale 5, and in conjunction with this operation knob, the set temperature 6 can be determined freely using the pointer 7 on the upper panel.By energizing, the coil LIO of the rotating part is formed between the iron core 9 and the outside. Received by concentric type 12, bearing 11
Support. Torque is generated according to Fleming's left hand rule, and the pointer 7 moves. A metal memory alloy 8 is used for the brake spring of the pointer 7. Fig. 3 shows an electric circuit.The circuit is turned OFF by receiving the moving pointer 7 by the switching element 13, and then turned ON by the switching element 14 via the starting operation self-holding circuit M1B, and the pointer This is a control circuit that controls with the transfer of 7. High output can be obtained by providing an additional output circuit. In FIG. 4, the coils L for generating rotational torque are made of metal memory alloys RK1 and RK2, but the operating characteristics of the metal memory alloys are additive. Humidity is input to the metal memory alloy through a moisture contact A in the electrical circuit, which represents the point of contact with the moisture in the air. Figure 5 shows an enlarged view of the humidity setting knob 4 and scale 5. Figure 6 shows a thermometer based on a similar principle.

[Function] The aim is not to physically control the spring for controlling the pointer of a meter, but to use a metal memory alloy to obtain movable torque as well as braking, and the rotational moment is used as a switching element. improves the performance of Similarly, the sensor of a high-performance hygrometer uses superconducting thermocouple wire to ensure the flow of electrons as a conductor with zero electrical resistance, regardless of the presence of an electrical path for moisture.

[Example Fig. 7 shows a hygrometer with water tank I7 attached and water tank 17]
It is a thermometer without a hole, and has holes 18 in the outer box to improve ventilation. FIG. 8 shows the contact point A between the metal memory alloy and moisture. In FIG. 10, a humidity contact A is attached to a thermocouple wire 20 to serve as a humidity detection section.

17 is a water tank. FIG. 11 shows a conductor a using a superconducting material with zero electrical resistance. A conductor is a pair of stranded wires. Figure 12 shows a thermocouple in the form of a concentric cable, in which the conductor 21 and the superconducting wire a are connected at a connection point 22, and the conductor has an elongated shape.
The conductor and the conductor are made of the same material and are screwed together to form a joint 23, which is connected to the red membrane wire 24. 2B is an insulator and is fixed with a stopper 24. The hygrometer configured as described above has mechanical strength unlike a glass tube filled with alcohol or the like. Moreover, since it is connected to an electric circuit, it is easy to control electrically.

For the reasons mentioned above, measuring and controlling atmospheric humidity varies in accuracy depending on the economic cost, but it is not just an instrument for measuring humidity, but is also an instrument for controlling humidity.

[Effects of the Invention] As explained above, the present invention has a simple structure in which a humidity ∆-1 measuring device is attached to a thermometer, and allows easy control of atmospheric humidity using electrical equipment. This has the effect of making it possible to control humidity and systematize comfortable air conditioning.
