Layered type electric water heater

Abstract

The invention discloses a layered type electric water heater. The layered type electric water heater comprises an inner container, the inner container is internally provided with a cold water box, a heating storage water box and a hot water box, a cold water communicating pipeline is arranged between the cold water box and the heating storage water box, a hot water communicating pipeline is arranged between the hot water box and the heating storage water box, the upper end of the cold water box is connected with a water inlet pipeline, the cold water communicating pipeline, the hot water communicating pipeline and the water inlet pipeline are all provided with water level adjustment and control valves, the lower end of the cold water box is connected with a cold water outlet pipeline, thelower end of the hot water box is connected with a hot water outlet pipeline, the cold water box is internally provided with a first water level sensor, the hot water box is internally provided with asecond water level sensor, and the heating storage water box is internally provided with a temperature sensor, a third water level sensor and a plurality of electric heating pipes. The layered type electric water heater is simple in structure and easy and convenient to operate, the function of heating water rapidly and efficiently can be realized, the different requirements for the water use quantity of users are met, and waste of energy sources is avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a layered electric water heater. Background technique [0002] In the prior art, electric water heaters are becoming more and more popular among consumers due to their convenient use and fast heating process. Electric water heaters refer to water heaters that use electricity as energy for heating. One of the water heaters. At present, the electric water heaters on the market are mainly composed of an inner tank, an insulation layer, a heating element and a shell. The inner tank is the core component of the electric water heater. The tube heating principle is used to heat the cold water in the inner tank as a whole. This method has the following defects: [0003] (1) The heating is slow. If you want to heat quickly, you must increase the power of the electric heater, which will increase the power load per unit time. The general household and commercial circuits need ...

AI Technical Summary

Problems solved by technology

[0003] (1) The heating is slow. If you want to heat quickly, you must increase the power of the electric heater, which will increase the power load per unit time. The general household and commercial circuits need to be modified to adapt to high-power water heaters, causing unnecessary trouble and waste;

[0004] (2) If you use less hot water at one time, such as washing your face, brushing your teeth, washing dishes, etc., it will cause waste to heat the entire water storage tank to the required temperature. , the small water storage tank cannot supply hot water immediately

[0005] Therefore, the existing electric water heaters cannot meet the needs of various users, causing serious waste of electric energy (the hot water in the inner tank will gradually cool if the heat preservation function is not turned on), which does not match the development trend of energy conservation and environmental protection , still needs to be further improved
