Intelligent energy-saving water dispenser

Abstract

The invention discloses an intelligent energy-saving water dispenser, which comprises a capacitance step-down power circuit, as well as a microwave induction controller, a mono-stable time delay circuit, a delay, a heater and a self-checking circuit which are connected to the capacitance step-down power circuit, wherein the microwave induction controller and the mono-stable time delay circuit are connected; the delay and the mono-stable time delay circuit are connected; the delay and the heater are connected; and the self-checking circuit is connected to the delay so as to acquire voltage values at two ends of the delay and to transmit an alarm signal when the voltage values at two ends of the delay reach a preset voltage value. According to the intelligent energy-saving water dispenser disclosed by the invention, the microwave induction controller is used for detecting surrounding situations of the water dispenser, so that the circumstance of misjudgment is prevented from occurring easily, and the microwave induction controller is capable of working as being arranged at the back of a plastic panel of the water dispenser, so that the appearance of the water dispenser is not damaged. The self-checking circuit is used for conducting self-checking on the delay, so that fault in the delay, if occurring, can be automatically detected and the status of the circuit can be informed to a user timely; and the water dispenser is simple in circuit structure and low in cost.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water dispenser. Background technique [0002] When the existing water dispenser is in use, when people or moving objects enter the surroundings, it is often possible to use the water dispenser, and a pyroelectric sensor is used for detection. Since the pyroelectric sensor is particularly sensitive to heat sources, it is easy to malfunction. And it is also difficult to install the water dispenser, so a kind of intelligent water dispenser that can accurately detect the state around the water dispenser is needed. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide an intelligent water dispenser that can accurately detect the surrounding conditions of the water dispenser. [0004] The purpose of the present invention is achieved like this: [0005] The intelligent energy-saving water dispenser provide...
