Technical Field

The utility model belongs to the technical field of hot water heating technique and specifically relates to indicate a difficult incrustation scale and energy-conserving portable hot water electric fan heater that produces.

Background

The common heating equipment in our daily life is respectively provided with an air conditioner, an electric heater and a wall-mounted furnace, and the common heating equipment has the following characteristics:

the air conditioner heating is mainly commonly used in southern areas, and is less applied in northern areas, firstly, the central heating is performed in northern areas, secondly, the temperature in northern areas is generally low, the heating capacity of the air conditioner at 5 ℃ is greatly reduced, so that the air conditioner heating system is not greatly suitable for northern areas, and the air conditioner heating cost is higher, except the purchase and installation cost, the power consumption is very high in the subsequent use process.

The electric heater is a very convenient heating device, the heat dissipation principle is that surface materials are utilized to radiate and diffuse, or heat is generated according to the convection heat transfer principle, indoor air is directly heated, and the purpose of improving the room temperature is achieved.

The wall-mounted boiler comprises an electric wall-mounted boiler and a gas wall-mounted boiler, wherein two heating modes of the electric wall-mounted boiler are generally adopted, one mode is a device for converting electric energy into heat energy, the principle is simple, the electric wall-mounted boiler is a pure resistance type electric appliance, the other mode is an electromagnetic heating mode, molecules of a metal water pipe generate high-speed irregular motion through electromagnetism and collide and rub with each other to generate heat energy, however, electromagnetic interference can be generated through a plurality of heating devices utilizing electromagnetic heating at present, EMC authentication can not be passed, the gas wall-mounted boiler takes natural gas, artificial gas or liquefied gas as fuel, the fuel is output through a burner, after being combusted in a combustion chamber, the heat is absorbed by a heat exchanger to be heated, circulating water in a system passes through the heat exchanger, is heated in a reciprocating mode, so that the heat is continuously output to a building, a heat source is provided for the building, no matter the electric wall-mounted boiler or the gas wall-mounted boiler, the wall-mounted stove is installed in a more limited way, the wall-mounted stove is preferably installed synchronously with decoration, otherwise, the problem that radiating fins and circulating pipelines are exposed exists, the integral attractiveness of a living room is affected, the purchase, installation and maintenance costs are high, and the gas-fired wall-mounted stove needs to be installed in places with good ventilation, such as balconies, kitchens and the like; when the water heater is used, water is heated by the electric wall-mounted boiler, hot water is sent to an indoor room by the water pump for heat dissipation, the water returns to the electric wall-mounted boiler for heating after heat dissipation, the water capacity of the whole circulating pipeline is about 100 liters, and for convenience, the water in the circulating pipeline is generally tap water, however, due to the water quality problem, after the water heater is used for a period of time, scale can be generated on the inner wall of the circulating pipeline, more than 90% of the generated scale can be concentrated at a heating position, which can affect heat exchange or cause dry burning, certainly, the scale problem can be relieved by using purified water or distilled water, but the price of the purified water and the distilled water is high, the cost of a user can be increased by using a large amount, and the tap water is not convenient in use; in addition, when heating is stopped, the water temperature of a circulating pipeline is slowly reduced, the circulating water temperature must be kept above 5 ℃ to prevent the pipeline from freezing, the energy loss of temperature reduction and heat preservation is above 6KW, when heating is started, the water temperature of the pipeline is increased from 5 ℃ to above 55 ℃, a wall-mounted furnace with 1 ten-thousand watts needs to consume more than 35 minutes, the power consumption is about 6KW, and when a family goes to work, heating is not used in the daytime, and electric energy above 12KW is wasted in the starting and stopping actions; the key shortcoming of hanging stove is exactly need to use a large amount of circulating water, except the wait of heating time, also extravagant heating and the energy of cooling process to use to produce the incrustation scale after a period of time easily, cause inconvenience for the user's heating in the north.
