Transformer for reservation type water heater

Abstract

The invention provides a transformer for a reservation type water heater. The transformer is provided with a plurality of voltage positions; an output end of each position is connected to a corresponding heating rod; the plurality of positions can be superimposed in use; and each voltage position corresponds to a heating time range which is calculated by a central computer controller according to factors such as actual environmental temperature. Each time the water heater is reserved to heat, the water heater can automatically select one voltage position for heating according to an input preparation time, cuts off a power supply when heating to the required position, and displays a prompt for completing heating at a remote control end simultaneously; after confirmation, the transformer can cut off all heating circuits automatically; and otherwise, the water heater enters a constant temperature protection mode. The invention has the advantages of adopting a multi-level heating direct-heating transformer, connecting the tail end of the transformer to an electric heating rod directly for heating water, improving the heating efficiency, along with easy control, high speed and convenience.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer for a reserved water heater. Background technique [0002] The functions of the transformer mainly include: voltage transformation; current transformation, impedance transformation; isolation; voltage stabilization (magnetic saturation transformer); autotransformer; high-voltage transformer (dry type and oil-immersed type), etc. Transformer Commonly used iron core shapes are E type and C type iron core, XED type, ED type. Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, and box-type transformers. Electrical test transformer corner transformer. [0003] The most basic form of a transformer, consisting of two coils wound wit...

Problems solved by technology

[0005] However, water heaters have defects in varying degrees. For example, solar water heaters cannot be used in rainy and cold seasons; gas water heaters are often frightened due to fear of gas leakage, and if the indoor ventilation is poor, there is a serious hidden danger of carbon monoxide poisoning. , when the gas water heater is working, part of the heat is discharged from the chimney to the outside with the harmful flue gas, the thermal efficiency is very low, and it is not conducive to environmental protection

[0006] Generally, when using a traditional electric water heater, you need to fill the water heater with water first, and then turn it on for heating. It takes about 30 minutes to wait for each heating. The electric heating water heater has a good standby heating function, but the standby also brings a certain loss, which is undoubtedly a shortcoming for the electric water heater which consumes a lot of power.
