Description

Efficient fast water heater

The utility model relates to a kind of water heater, particularly a kind of efficiently water heater fast.

Water heater is an indispensable sanitary ware in the Modern Family, and people have carried out diversified design and research in order to make water heater energy savings, economy, material benefit, safety.The water heating there are two kinds of methods: the one, direct heating, the 2nd, indirect.Directly two electrodes are promptly drawn in heating in water, do heater with water, and this method heating is fast, and the efficient height is simple in structure, but is absolutely unsafe.The method of indirect has a variety of, comprising electrothermal tube heating, electric furnace heating, boiler heating, coal gas heating etc.

Existing water heater mainly contains two kinds of electrothermal heater and gas heaters.Though gas heater is simple in structure, cheap, has major safety problems, combustion gas produces a large amount of carbon monoxide in burning, human life is caused a significant threat; The electrothermal heater utilizes heating to the water container indirect, existing protection against electric shock effect is electrothermal heater's heater preferably, though all adopted the tubular electrothermal element that directly links to each other with electrical network, the outside of this element is a metal-back, inside is resistance wire, the insulating materials of falling heat-transfer better performances between the two, this heater mainly guarantees user's safety by the insulating properties of insulating materials, but insulating materials is after a period of time uses, understand aged deterioration, also be prone to the generation of electric shock accidents.In addition, water storage is limited in big, the water tank of low, the power consumption of electrothermal heater's thermal efficiency, the heating-up time is long.

The purpose of this utility model is that to overcome in the prior art gas heater dangerous; The shortcoming that electrothermal heater's power consumption is big, the heating-up time is long, the thermal efficiency is low provides a kind of thermal efficiency height, rapid, the little easy to use and safe and reliable again water heater of power consumption of intensification.

The inventive point of realizing the utility model purpose is: change in the prior art water heater by a coal gas with utilize the mode of heating to the water indirect, big according to the loss factor of water, can absorb microwave well and be translated into the principle of heat energy, adopt microwave heating equipment to water carry out efficiently, Fast Heating.Concrete structure is: efficient fast water heater, comprise microwave power source, microwave applicator and water inlet pipe and water outlet pipe, it is characterized in that: microwave applicator is the waveguide type microwave applicator, and the output port of waveguide type microwave applicator and microwave power source connects, and inlet tube and outlet tube is bound up on the microwave applicator.Said waveguide can be dielectric loaded waveguide or composited waveguide.Microwave applicator is arranged to have the length of several wavelength on E, H face both direction, thereby the waveguide type microwave applicator is expanded to the multimode stove wave heater that declines, and such multimode stove formula heater will be kept large numbers of modes of resonance on given frequency range.Said microwave applicator is provided with little mesh, and water inlet pipe and water outlet pipe and little mesh connect.Be provided with the water pipe that the low-loss material of transmissive microwave is made in the said microwave applicator, water pipe is arranged in the microwave applicator with the meander-like structure, and two ends of water pipe connect with water inlet pipe and water outlet pipe respectively.The microwave input system is made up of microwave power source that fits together and waveguide feeder system, microwave energy is input in the heater by the waveguide mouth, microwave applicator can adopt many mouthfuls of irradiations to improve heating uniformity, microwave applicator also can be by the input of several microwave power sources, each microwave source by coupling aperture separately in the microwave energy input heater.The intake-outlet of microwave applicator is provided with microwave and leaks energy TVS and absorbing material.

Because heating using microwave is different from general being heated by radiation conduction-type from outward appearance to inner essence by external heat source, but the volume that water causes because of dielectric loss in electromagnetic field heating, the loss factor of water is very big, it can absorb microwave well and be translated into heat energy, and the advantage of this heating is tangible.The utility model is owing to adopted the closed waveguide structure, microwave power can not leak, easy to use and safety, there is not the threat of electric shock, there is not the danger of exhaust emission and anthracemia yet, the utility model had both overcome the danger that the generation waste gas personnel that cause poisoned when gas heater used, the danger and the power consumption that have overcome electrothermal heater's electric shock again are big, heating-up time is long, the shortcoming that the thermal efficiency is low, realized safety to water, efficient and Fast Heating, the thermal efficiency of the present utility model can reach more than 70% and firing rate fast, immediately hot water can be gone out, four seasons hot-water supply can be satisfied substantially.

Now be described further with embodiment in conjunction with the accompanying drawings.
