Electric heater with electricity-proof wall

Abstract

The invention relates to an electric heater with electricity-protection wall, comprising water heater and two radiator and electricity-protection walls which are set between the inlet of water heater and the water outlet hole of radiator and the outlet of water heater and the water inlet hole of radiator. Thermal expansion water tank is set at the top of radiator and exhaust valve is set at the top of the thermal expansion water tank. The water heater comprises body and heater in the body. The outlet port is set near the upper end of body and the inlet port is set near the lower end of body. Heating cavity is set in the body and the heating cavity is connected with the inlet port and the outlet port. The heater is set in the heating cavity. The invention adopts water as the heat transfer medium, adopts conventional metal radiator as radiator, adopts semiconductor heater or other high-quality electro-thermal component as heating device, and adopts special electricity-protection wall structure to provide independent heating system for each group of radiator so that water is cycled naturally between the radiator and the heating system. It is provided with safety, high efficiency, energy saving and environmental protection.

Description

technical field [0001] The invention relates to an electric heater, in particular to an electric heater with an electric protection wall. Background technique [0002] Existing electric heaters can be divided into two categories, one is the electric heater with heat transfer oil as the heat transfer medium, that is, the electric heating oil heater; the other is the electric heater in which the heating element directly heats the air, such as an air conditioner, Electric heater etc. The electric heating oil heater uses heat transfer oil as the heat transfer medium. Due to the poor thermal conductivity of the heat transfer oil, it takes a long time to heat the oil in the electric heater to the working temperature, and consumes a lot of electric energy; and the viscosity of the oil is large and the circulation is slow. The thermal efficiency is low, so it has the disadvantages of slow heating rate and poor heat dissipation effect. Although air conditioners, electric heaters, e...

The electric heating oil heater uses heat transfer oil as the heat transfer medium. Due to the poor thermal conductivity of the heat transfer oil, it takes a long time to heat the oil in the electric heater to the working temperature, and consumes a lot of electric energy; and the viscosity of the oil is large and the circulation is slow. The thermal efficiency is low, so it has the disadvantages of slow heating rate and poor heat dissipation effect

Although air conditioners and electric heaters have the advantages of fast heating speed, the hot air generated is not evenly distributed indoors, and the dry hot air is directly blown to the human body, which makes people feel uncomfortable.

[0003] The above two electric heaters do not have the function of humidifying the air during use. As the indoor temperature rises, the evaporation of water in the air is accelerated, making people feel dry mouth and irritability, which is harmful to the human body's respiratory system and heart. The vascular system is affected, which is not conducive to human health

[0004] Compared with the above two electric heaters, the traditional heating system using water as the heat transfer medium and metal radiators in northern my country has obvious advantages in terms of comfort and use effect, but the traditional electric heating system in the north The central heating system of the appliance has a lot of piping work, which consumes a lot of labor and materials, and the hot water loses a lot of heat energy during the pipeline transportation process, and is not suitable for individual households.
