Title:
WATER DRYING-UP SENSING AND WARNING DEVICE FOR HOUSEHOLD PRODUCTION UNIT OF SOYBEAN MILK, BEAN CURD, AND WATER-RICH BEAN CURD
Document Type and Number:
Japanese Patent JP2003219828
Kind Code:
A
Abstract:

To provide a water drying-up sensing and warning device for a household production unit of soybean milk, bean curd, and water-rich bean curd, capable of preventing the production unit from being damaged, even when a user operates the unit without feeding water thereinto, by making the production unit not operated unless the water is fed into a main body of the unit.

This water drying-up sensing and warning device is composed of a grounding electrode E1, a signal electrode E2, an electrical resistance R24, a switching transistor Q9, a controller I.C 1, another electrical resistance R21, another switching transistor Q5, and a buzzer BUZ, wherein the grounding electrode E1 and the signal electrode E2 are each joined to two members selected from components mounted on the main body (1), the electrical resistance R24 is connected to the signal electrode E2, the switching transistor Q9 is connected to the electrical resistance R24, the controller I.C 1 is connected to the switching transistor Q9 and outputs a control signal for warning nonexistence of the water when the water is not fed, the electrical resistance R21 is connected to the controller I.C 1, the switching transistor Q5 is connected to the electrical resistance R21, and the buzzer BUZ is connected to the switching transistor Q5.
