Description

Electric water heater
Technical Field
The utility model relates to a life electrical apparatus technical field, in particular to electric water heater.
Background
The electric water heater is a water heater which heats by taking electricity as energy. The electric water heater can be divided into a water storage type (also called a positive displacement type or a heat storage type), an instant heating type and an instant heating type (also called a semi-water storage type) according to the heating power.
Although the volume of the common quick-heating electric water heater is almost the same as that of the double-mode electric water heater, the internal structure of the common quick-heating electric water heater is greatly different from that of the double-mode electric water heater, the ratio of the quick-heating electric water heater to the water storage type electric water heater is only smaller in volume and higher in power, so that the heating speed is higher than that of the water storage type electric water heater, but the quick-heating electric water heater can not achieve instant heating in spring and autumn and also needs preheating, namely waiting is needed, and the double-mode electric water heater can use an instant heating mode in spring, summer and autumn.
The development of the electric water heater is over ten years, the technology of the water heater is continuously improved, innovative products such as an electricity-proof wall, an electricity-proof brake, 3D quick heating, frequency conversion capacity increasing and the like appear in the industry, the electric water heater is continuously improved in the aspects of safety, energy conservation, heating speed, water yield and the like, and the market sales is continuously increased all the year round. Along with the improvement of living standard in recent years, people have more and more demand on water consumption, so the marketable volume of the electric water heater is improved from about 40 liters in 2000 to about 60 liters nowadays, and the water heater is always a province of 80 liters large-volume water heaters in China such as Hubei, Hunan and Guizhou.
However, the existing electric water heater mainly has the following defects when in use:
firstly, because the electric water heater needs to heat water for a long time, the internal structure is easy to generate the danger of electric leakage in the using process, because the electric leakage can be stored in a circuit and can also be stored in the water heater, a single detection mode is easy to have deviation, and once the electric water heater is used by people in the electric leakage process, serious safety problems can be caused, and potential safety hazards exist; secondly, the electric power of the quick heating type electric water heater is large, generally 5000-7500W, the electric equipment is easy to damage, and other household electricity consumption is influenced, so that users can purchase the electric water heater without using the electric water heater, economic loss and waste are caused, and for the heat storage type electric water heater, the water tank is full of water for a long time, so that heat loss is large, the water consumption cost is increased, the water tank is large in size, and a small bathroom cannot be installed and used; meanwhile, when the traditional electric water heater heats water, a single heating mode is adopted for heating, the convection effect of the water is small, the integral heating efficiency is reduced, the use is influenced, and particularly the use experience is influenced when hot water is needed. Fifth, the electric water heater and the heating device are independent, the toilet is generally heated by the bathroom heater or the electric hot air, the heating efficiency is low, the temperature of the toilet can only be raised to 12 ℃ in winter, and the power consumption is large. Sixthly, in order to avoid electric leakage when water is used, the existing water heater can cut off heating current when hot water is used, if the water consumption for one time is large, a large-capacity water heater needs to be purchased, the large-capacity water heater causes slow heating, natural cooling is not carried out for a long time, and electric energy is wasted.
However, compared with other water heaters, the electric water heater still has the unique advantages of convenient use and no danger of gas poisoning, so the electric water heater is still worth developing, but the defects and the shortcomings of the electric water heater need to be thoroughly solved, and the electric water heater becomes a perfect electric water heater, and the utility model aims to realize the purpose.
