Intelligent type omnibearing protection, auto-reclosing, multipurpose flowing water type electric water heater

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...

AI Technical Summary

Problems solved by technology

[0008] For nearly half a century, due to the depletion of oil and gas resources and the rising prices, coupled with the pollution of the atmosphere caused by the use of such energy, people have been seeking to quickly produce products suitable for showers, toilets, foot baths and toilets. The method of using hot water for braces, etc., and manufactured electric water heaters. In order to improve thermal efficiency, some manufacturers have produced so-called flow-type electric water heaters in recent years. In fact, they are mostly storage-type electric water heaters, and their shortcomings have been mentioned in the previous section. In addition, most of the hot water produced by this kind of water heater can’t be used up, which is wasted in vain. The huge water tank makes the installation space too large and the installation cost increases, so that the cost of the hot water produced is increased, the price is expensive, and the cost performance is greatly reduced. , not recognized by most families

In recent years, some products claim to be [currently the world's most advanced high-tech "××" technology manufacturing, which is a replacement product for faucet water heaters] but the reason is that the NTC heating element is sealed and soaked in the faucet without any protection. facilities, and there is no automatic control of water temperature, so the water temperature is sometimes high enough to scald people, and sometimes low enough to freeze people. In addition, the NTC electric heating element cannot be dry-burned. When there is a lack of water or water, the electric heating element will be blown. Spark discharge will burn through the insulation, and a life-threatening leakage voltage will be generated. The entire shower device and the water flowing out will have a leakage current. People who take a shower will get an electric shock, and in severe cases, they will die due to an electric shock

All in all, there is still no real cheap, safe and reliable flow-type (or instant) electric water heater used in the shower at present.
