Description

Microwave water-heater

The utility model relates to a kind of hot water apparatus that heats cold water, especially can be efficiently, Fast Heating cold water, and the microwave water-heater of degerming, safe handling hot water.

At present, known electric heater is pyrotoxin with the electrothermal device all, heats cold water by heat conducting mode.But, owing at first need heater element itself, just be restricted like this so conduct firing rate to high thermal source place far away slowly again.Secondly, have quite a few bacterium not eliminate by heat conduction heating under the bathing water temperature, the open people of skin pore is undoubtedly a kind of threat during for bathing.Once more, the thermal efficiency is not ideal enough, and this certainly will give using and bring many inconvenience and hidden danger.

The purpose of this utility model provides a kind of microwave water-heater.It can not only heat cold water expeditiously, and than general electrical heating fast tens times, and can also sterilizing, safe handling.

The purpose of this utility model is achieved in that microwave takes place and control device is similar to common microwave stove, promptly be electrically connected by high-tension transformer, magnetron, high-voltage diode, high-voltage capacitor, piezo-resistance, digit absobing selector, electrothermal relay, timer or power controller, timing or power control switching, master switch, the microwave of generation is by in the microwave heating chamber of antenna by waveguide and coupling mouth input microwave water-heater.Place one section water pipe or a water tank in microwave heating chamber, water pipe or water tank be all by the transmissive microwave, and do not absorb microwave and have plastics or other non-conductive material of heatproof more than 100 ℃ and make.Make water pipe or water tank be fixed in suitable position by filled thermal insulation materials heating chamber then with same performance, also fill insulant material outside heating chamber and between the shell, then two outlet passes of water pipe two ends or water tank be connected to can stop on the heating chamber wall that microwave leakage again can the mesh mouth of a river of water flowing on, this mouth of a river is to form the little porose area in circle territory earlier by punching press on the wall of METAL HEATING PROCESS chamber, its aperture is can stop that microwave leakage is the preceding maximum of extracting, and then form one deck plastic insulating layer water power is separated fully by being injection-moulded in metal naked hole inwall and end face thereof, plastic eyelet in the roundlet zone, center is a through hole, and the hole in the outer collar region is that plastics are annotated real core hole and the roundlet zone and the center of circle coincidence of large circle zone of filling.Mesh mouth of a river one side outwardly can tap into outlet pipe, and a water receiving pipe in the heating chamber also can link to each other with the water tank mouth of a river or the bottom is injected into one.Magnetron and high-tension transformer all are equipped with water jacket, and they and water inlet pipe and water outlet pipe are connected or connected respectively just can make water preheat or concurrent heating, contacts with water inlet pipe and water outlet pipe then.Like this when water through water jacket, enter water pipe in the microwave heating chamber of microwave water-heater or water tank by the mesh mouth of a river again when another mesh mouth of a river and outlet pipe flow out, microwave in the heat radiation of high-tension transformer, magnetron and the feed-in microwave heating chamber just carries out efficient Fast Heating to water, and reaches degerming safe handling purpose.

Owing to taked such scheme, just can be efficient to water, Fast Heating, degerming safe handling, heating target is the water in mobile or the water tank simultaneously, the uniformity to the microwave coupling is less demanding, so it is simple in structure, temperature range is little in addition adopts the water jacket cooling both to simplify circuit structure with magnetron and high-tension transformer, has increased the degree of safety of element again, has also saved electric energy simultaneously.
