Quick timing controller of mechanical electric water heater

Abstract

The invention relates to a quick timing controller for a mechanical version of an electric water heater, which is characterized in that it includes: a 220V AC power supply, a long-delay charging circuit, a monostable circuit, a mechanical version of an electric water heater control circuit, a working state indicating circuit, and a 12V half-wave rectification filter Stabilized power supply; the model adopted by the time base circuit IC1 in the monostable circuit is NE555. The mechanical version of the quick timing controller for the electric water heater of the present invention only adds a few common components to the delay circuit of the typical time base circuit, which realizes the purpose of the ultra-long delay circuit made with the time base circuit. This not only solves the problem that the mechanical version of the electric water heater cannot be timed, but also solves the problem of wasting energy due to repeated heating after the mechanical version of the electric water heater is powered on. On the basis of not changing the typical delay circuit made by using the time base circuit, it effectively solves the technical problem that has not broken through the ultra-long delay of the time base circuit for a long time.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a mechanical version of a quick timing controller for an electric water heater. Background technique [0002] Time-base circuits are widely used in delay automatic control, but for a long time, using time-base circuits to make circuit design and production technology with a delay of more than 30 minutes is a bottleneck that is difficult to break through, which greatly limits the delay of time-base circuits. range of use. In order to effectively solve the technical problem that has not broken through the ultra-long time delay of the time base circuit for a long time, on the basis of not changing the typical time delay circuit made by the time base circuit, the mechanical version of the electric water heater quick timing controller described in the present invention is only in the typical Adding several common components to the delay circuit of the time base circuit reali...
