Abstract

The utility model discloses a heating device of a microwave water heater, which uses microwaves as energy. The utility model has the structure that the heating device of a microwave water heater comprises a waveguide tube; a central water pipe is arranged in the waveguide tube; a magnetron is installed on the tube wall of the waveguide tube; the outer side of the central water tube is sheathed with an auxiliary water tube; an upper end of the central water tube and the lower end of the central water tube respectively are provided with a small hole which is communicated with an inner cavity of the auxiliary water tube. Because of the arrangement of the auxiliary water tube, the temperature of water in the central water tube can rise under the direct action of the microwaves, and besides, the temperature of the water in the central water tube can quickly rise by the heat conduction of water in the auxiliary water tube to the water in the central water tube; the utilization efficiency of microwave energy is improved.

Description

The heater of microwave water-heater

It is the water heater of the energy with the microwave that the utility model relates to a kind of, relates in particular to the heater of microwave water-heater.

The heater of microwave water-heater mainly comprises: waveguide, be provided with the center water pipe in the waveguide, and magnetron is installed on the tube wall of waveguide; During work, make magnetron send microwave by a cover control device, microwave reflects back and forth in waveguide, reflects, and reaches the purpose that the water in the centering edema with the heart involved pipe heats; In actual use, the heat exchange efficiency of such heater is not high.

The purpose of this utility model is to provide the heater of the higher microwave water-heater of a kind of heat exchange efficiency.

For realizing above-mentioned purpose, the technical solution adopted in the utility model is: the heater of described microwave water-heater mainly comprises: waveguide, be provided with the center water pipe in the waveguide, and magnetron is installed on the tube wall of waveguide; Also be set with auxiliary water tube outside the water pipe of center, the upper and lower end of center water pipe offers aperture respectively and communicates with the inner chamber of auxiliary water tube.

Further technical scheme of the present utility model is: be respectively installed with cooling jacket on magnetron and magnetron dedicated transformer.

The utility model has the advantages that: one, owing to be provided with auxiliary water tube, under the effect of microwave, water in the auxiliary water tube also constantly heats up until thermal balance, like this, water in the water pipe of center is not only under the direct effect of microwave and heat up, and being subjected to water in the auxiliary water tube again to its heat conduction, it is faster that water in the water pipe of center is heated up, and improved the utilization ratio of microwave energy greatly; Two, when operate as normal, magnetron and magnetron dedicated transformer all can heating ups, usually with fan they are forced cooling, and the utility model has been set with cooling jacket on magnetron and magnetron dedicated transformer, like this, not only can make full use of the energy to carrying out preheating earlier through the water in the cooling jacket, and saved the fan in order to cool off originally, and make control circuit simpler.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the profile of the waveguide part among Fig. 1.

As shown in Figure 1 and Figure 2, the heater of microwave water-heater described in the utility model mainly comprises: waveguide 2, be provided with center water pipe 11 in the waveguide 2, and magnetron 4 is installed on the tube wall of waveguide 2; Also be set with auxiliary water tube 9 outside center water pipe 11, the upper and lower end of center water pipe 11 offers aperture 10 respectively and communicates with the inner chamber of auxiliary water tube 9.In the present embodiment, on magnetron 4 and magnetron dedicated transformer 5, be respectively installed with cooling jacket 3 and 6.

During work, cold water enters through water inlet 7, successively by cooling jacket 6 on the magnetron dedicated transformer 5 and the cooling jacket 3 on the magnetron 4, enter into center water pipe 11 through water inlet pipe 8 again, water in the center water pipe 11 also enters into auxiliary water tube 9 simultaneously through aperture 10, after outlet pipe 1 outflow.Like this, water is through cooling jacket 6 and cooling jacket 3 time, at first accept the heat that magnetron dedicated transformer 5 and magnetron 4 come out and carry out preheating, also magnetron dedicated transformer 5 and magnetron 4 are cooled off simultaneously, to guarantee their operate as normal; Water after preheating enters into center water pipe 11 and auxiliary water tube 9, be subjected to the effect of the microwave that magnetron 4 sends and heat up, because center water pipe 11 only communicates by aperture 10 with auxiliary water tube 9, so although the water velocity in the center water pipe 11 is very fast, and the water velocity in the auxiliary water tube 9 is very slow, like this through after very fast a period of time, water in the auxiliary water tube 9 just is warmed up to peak---a kind of thermal equilibrium state rapidly, therefore, water in the center water pipe 11 just not only is subjected to the effect of microwave, and be subjected to water in the auxiliary water tube 9 to its conduction of heat, speed when programming rate compares without auxiliary water tube 9 is faster, has improved heat exchange efficiency greatly.
