Abstract

The utility model relates to a microwave water heater which can be rapidly and safely used for heating with high efficiency. The generation and the control of microwaves are the same as an ordinary microwave oven. The microwaves are fed in a microwave heating cavity of the water heater; a water pipe with definite length or a water tank is arranged in the cavity; materials are used for making the water pipe or the water tank, the microwaves can penetrate through the materials which do not absorb the microwaves and resists heat with temperature of higher than 100 DEG C. Both ends of the water pipe or a water inlet and a water outlet of the water tank and the bottom of the cavity wall are connected with a valve which is used for stopping microwaves from leaking and admits water to pass, and one end is connected with a spray head and the other end is connected with an outlet of a heat exchanger underfoot in series; the other end of the heat exchanger is connected with a water source. An exchanging heat source comes from warm water after the warm water is used for showering, and cold water which passes through the heat source is preheated. Therefore, the heat efficiency is improved, the heating time is shortened and the utility model can be used for sterilization.

Description

Microwave water-heater

The utility model relates to a kind of cold water heater, especially efficient Fast Heating, the microwave water-heater of degerming safe handling.

At present, known electric heater is to generate heat by heating, by heat conduction heating cold water, but, because heat conduction velocity is very slow, increased user's stand-by period, the water that is heated to the bathing temperature by conduction pattern has quite a few bacterium not eliminated in addition, is undoubtedly a kind of hidden danger the people of this opening of the pores during for bathing.

The purpose of this utility model provides a kind of microwave water-heater, and it can not only make firing rate than general electric heater fast tens times, and can also degerming, and use that can safety.

The purpose of this utility model is to realize like this, by microwave take place and control element promptly: magnetron, high-tension transformer, kenetron, high-voltage capacitance, motor, piezo-resistance, digit absobing selector, electrothermal relay, timer, be electrically connected the same with control circuit takes place with the microwave of micro-wave oven in power controllers etc., the microwave that produces is by antenna, waveguide, the microwave heating chamber of coupling mouth feed-in water heater, in microwave heating chamber, place water pipe or a water tank of certain-length, then two outlet passes of the two ends of water pipe or water tank are drawn outside the chamber by stopping the valve that microwave leakage can make water pass through again, the outlet pipe of one termination shower nozzle, one end and underfooting heat exchanger links to each other, and the water inlet of heat exchange links to each other with the water source.The top cover of heat exchanger has netted aperture, can flow into the flat commuting case that closes the shape heat exchanger to the warm water after the bathing by aperture, dish has the water pipe of certain-length in commuting case, and draws commuting case from two ends, and a termination water source one termination water inlet tube of water heater.The water that heat exchange finishes enters sewer by the overfall of bottom.Its interior garden heart of valve that stops microwave has a netted conductor, and the size of mesh is preceding extraction maximum can not leak microwave, thereby water can be flow through smoothly, and microwave is blocked in the chamber.

Owing to taked such scheme, just can carry out efficiently, the purpose of quick, heating, safe degerming use water.
