Device for sensing and alarming absence of water in a home machine for manufacturing soybean milk, watery bean curd, and bean curd

Abstract

Disclosed is a device for sensing and alarming absence of water in a home machine for manufacturing soybean milk, watery bean curd, and bean curd, which allows the home manufacturing machine to be operated only when the home manufacturing machine contains water, so as to prevent the machine from being operated by a user without water, thereby preventing the machine from getting damaged. The apparatus includes a plurality of components installed in a body. The device includes: a ground electrode and a signal electrode electrically connected to two selected in the plurality of the components, respectively; a resistor connected to the signal electrode; a switching transistor connected to the resistor; a controller connected to the switching transistor for outputting a control signal for an alarm when the absence of the water is sensed; a resistor connected to the controller; a switching transistor connected to the resistor; and a buzzer connected to the switching transistor.

Dependencies are inferred from the claim text.
