Description

Microwave water-heater

The utility model relates to a kind of water heater.

Water heater in the market mainly contains gas heater, electric heater and solar water heater etc.But all there is weak point in these water heaters.The gas heater security is relatively poor, and oxygen consumption is big, and intoxication accident easily meets accident.Electric heater is long heat time heating time, uses inconvenient.And the solar water thermal efficiency is low, is subjected to the influence of ambient weather factor bigger, uses also inconvenient.

The purpose of this utility model is exactly in order to address the above problem, and a kind of thermal efficiency height is provided, heating is fast, security is good and can not be subjected to the microwave water-heater of such environmental effects.

Technical solution of the present utility model:

The utility model adopts the microwave magnetron mode of heating, and water is directly heated, and is full and uniform and constantly water is heated in moment.Its thermal efficiency height, the instant outflow of the instant heating in water source confessed hot water continuously, and be very easy to use.The utility model is simple in structure, and cost is low, and firing rate is fast, is not subjected to any Effect of Environmental, and security is definitely reliable, the anything unexpected accident can not occur, has vast market prospect.

Fig. 2 is a decomposition texture schematic diagram of the present utility model;

Fig. 3 is the structural representation of the water-cooled magnetron of wooden utility model;

Fig. 4 is a helical form aqueduct schematic diagram of the present utility model.

As Fig. 1,2, the utility model is made up of magnetron 1 metal heated sealed chamber 2 and nonmetal aqueduct 3, the microwave energy follower 4 of magnetron 1 is connected with 2 sealings of metal heated sealed chamber by waveguide 5, nonmetal aqueduct 3 is arranged in the metal heated sealed chamber 2, its end is connected with the water source, and the other end is a hot water outlet.

Magnetron 1 of the present utility model can adopt existing like product, and as the magnetron in the micro-wave oven, it is made up of negative electrode, anode, permanent magnet, fin and microwave energy follower, and it adopts the blower fan type of cooling usually.

In the utility model, magnetron 1 preferably adopts water-cooled magnetron, as Fig. 3, closely be connected with insulation tube 7 at parcel cylindrical shape negative electrode and anode 6 peripheries, insulation tube 7 has the characteristics of high temperature resistance and good heat conductive performance, this is used for preventing the magnetron electric leakage, insulation tube 7 peripheries closely are connected with heat radiation sleeve pipe 8 again, they are an integral body, and on them, the lower end is equipped with permanent magnet 9, and integral body is arranged in the sealing shell 10, on the outer wall of radiating tube 8, be connected with a plurality of slot type fin 11 from top to bottom, each fin 11 can be the rectangle cell body, one through hole that matches with heat radiation sleeve pipe 8 external diameters is arranged on its bottom surface, make each fin 11 be fixed in successively from top to bottom on the outer wall of heat radiation sleeve pipe 8, and each slot type fin 11 is staggered successively to be installed, the right-hand member of a slice fin 11 stretches out promptly, and left indent, following a slice fin 11 is right indent and left end stretches out then, so alternately stagger and be installed on the heat radiation sleeve pipe 8, thereby form the mobile conducting shell of a cooling circulating water on heat radiation sleeve pipe 8 outer walls in sealing shell 10, two fin 11 topmost and bottom an end of two fin 11 connect respectively to stretch water inlet 12 and delivery port 13 arranged, the pipeline 16 and water source water inlet pipe 17 of water inlet 12 by being provided with control valve 14 and magnetic valve 15, be communicated with and connect, delivery port 13 links to each other with the import of nonmetal aqueduct 3 by pipeline 18, electromagnetism 15 and magnetron 1 are by electric controller 19 controls, sealing shell 10 end openings of magnetron 1 and 5 suitable for reading connections of waveguide, the end opening of waveguide 5 is connected with the center side wall in cylindricality metal heated sealed chamber 2, and the microwave energy follower 4 of magnetron 1 is positioned at waveguide 5.Nonmetal aqueduct 3 in the cylindricality metal heated sealed chamber 2 should be helical form, as Fig. 4, its outstanding solid centre in metal heated sealed chamber 2, length in the spiral part 20 of this aqueduct 3 and the heating chamber 2 is identical, length in its spiral part 20 and the heating chamber 2 is identical, the tail end of its spiral part 20 curved around after be connected with long straight tube 21 and pass heating chamber 2, the head end of the spiral part 20 of aqueduct 3 is connected with the delivery port 13 of fin 11 bottom by pipeline 18, and the termination of the straight tube 21 of aqueduct 3 is just as hot water outlet of the present utility model.

The utility model course of work is as follows; open the gauge tap of electric controller 19 earlier; make magnetic valve 15 and magnetron 1 energising work; then the water source flows into the mobile conducting shell of being made up of each fin 11 of cooling circulating water of magnetrons 1 through the water inlet 12 of magnetron 1 by pipeline 16 from water inlet pipe 17; its flow of inlet water is regulated control by control valve 14; the magnetron 1 that water in the above-mentioned fin 11 that flows to magnetron 1 produces high temperature during just to work carries out water cooling; the heat that the magnetron of water absorption simultaneously 1 produces has carried out preheating to water again; water after the preheating is from the nonmetal aqueduct 3 of delivery port 13 in pipeline 18 flows to cylindricality metal heated sealed chamber worker of magnetron 1 bottom fin 11; because aqueduct 3 has one section spiral part 20; then water just travels forward along hand of spiral rotation after entering this spiral part 20; the high-frequency microwave that this moment, magnetron 1 produced is sent through waveguide 5 and is positioned at the waveguide protective cover 22 of waveguide exit position (it leaks and is sprayed onto magnetron 1 when being used for preventing aqueduct 3 crackings to lead protective cover 22, causes its damage from its microwave energy follower 4.) send in the cylindricality metal heated sealed chamber 2, the water that flows in aqueduct 3 spiral parts 20 is carried out heating full and uniformly, and then again the water of the straight tube 21 of the aqueduct 3 that is positioned at heating chamber 2 centers is proceeded heating, be hot water from what straight tube 21 termination hot water outlets flowed out at last for user's use.So continuously work, just confess hot water continuously from hot water outlet, very easy to use.
