Abstract

The invention relates to a multifunctional flow type electric water heater with intelligent and comprehensive protection and automatic reclosing and consists of two parts: one part comprises a tap of the electric water heater with an electric heating component and an attachment thereof and the other part comprises a comprehensive protective breaker. The protective breaker also consists of two parts: one part is an air breaker and the other part is a multifunctional protector; the protective breaker can directly and synchronously monitor a plurality of physical quantity at the same time, such as power supply voltage, load current, leakage current, thunder and light induction, temperature increasing of the electric heating component, temperature of a water outlet, temperature increasing of a wire, etc., therefore, the electric water heater, a transmission line and a power supply operate under monitoring; once malfunction comes out, the protective breaker can cut off power supply automatically, meanwhile, an insulation electric heating component starts automatically for insulation of hot water; when malfunction is eliminated, the protective breaker can supply power with automatic reclosing after timelag. The invention can conduct fine-adjustment on the temperature of the water outlet of the electric water heater and can supply hot water for shower, washroom, clothes washing, table ware washing, foot soaking, etc. at the same time; the invention has safety and reliability while the price is low.

Description

1. Technical field

[0001] The invention belongs to the field of household electric water heaters and at the same time belongs to the field of electric appliance protectors, and is a novel household appliance in which the two are cleverly combined into one. The name is intelligent all-round protection, automatic reclosing, multi-purpose flow-through (or instant heating) electric water heater (hereinafter referred to as flow-type electric water heater).

[0002] Hot water is indispensable in family life, whether you do laundry, bathe, soak your feet, wash braces, etc., you need it. Devices that supply domestic hot water are collectively referred to as domestic water heaters, which occupy an important position in modern household appliances.

[0003] In foreign countries, household water heaters have a history of decades, and the most common type is currently used. If it is divided according to the heat source: there are four categories: electric water heaters, gas water heaters...

Embodiment Construction

[0010] The present invention can be achieved through the following measures. The present invention consists of two major parts, one is an electric water heater faucet with a PTC or NTC electric heating element and its accessories, and the other is an all-round protection circuit breaker. Three PTC (or NTC) heating elements and temperature sensor Rt1 are inserted into a copper bracket to monitor the temperature rise of the heating element. The four-position plug is connected with the four-position socket on the protector, and holes are drilled in the bracket to facilitate the passage of cold water. The groove for placing the electric heating element and the temperature sensor in the bracket is sealed with waterproof and high-temperature-resistant epoxy resin. The temperature sensor Rt2 is closely attached to the outlet pipe of the faucet of the flow-type electric water heater to monitor the water temperature. The temperature sensor Rt3 is bound on the transmission line to monit...
