Abstract
The utility model relates to an electric water heater, which uses silicon nitride ceramic materials as a heater. The electric water heater comprises an outer shell, a bottom board, a heating container, a temperature adjusting switch, and an intermediate relay. The electric water heater is characterized in that the heating container is provided with two to five sheets of silicon nitride heating boards which are installed in the staggered mode up and down. The heating container is divided into a plurality of heating zones by the heating boards. Cold water flows into the heating zones from water inlet pipes, becomes hot water after revolving and heating through each heating zone in sequence, and flows out from water outlet pipes k. The utility model has the advantages of quick heating, high energy efficiency, compact structure, small size, safety, etc.
Description
The utility model relates to continuous flow heater, promptly only produces the heater of heat when water flows, especially a kind of silicon nitride electric heater.
At present, the electric heater that occurs on the market has two kinds: (1). storage-type electric water heater, the characteristics of this water heater are that volume is big, generally adopt metal material to do heater, and it is slow to heat up, capacity usage ratio is the highest about 80%, useful life is not long, and moisture storage capacity is limited, must heat earlier, afterwards be incubated, also need heat again after the water that stores uses up, can not use continuously.(2). immediately heating water heater, this water heater also are to adopt the metal heater element, though be Instant heating type, also need wait one fen behind the half hot water to be arranged, and in view of the limitation of metallic heating body, complex structure, the capacity usage ratio of product are lower.
The purpose of this utility model is exactly to provide a kind of employing silicon nitride ceramic material as heater in order to overcome the deficiency that above-mentioned prior art exists, and has the immediately heating water heater of quick heating, capacity usage ratio height, long service life, rational in infrastructure, characteristics such as volume is little.
The purpose of this utility model can realize in the following manner:
It comprises shell, base plate, heating container, temperature regulating switch, auxiliary relay, it is characterized in that: heating container is provided with the silicon nitride heating board of 2～5 upper and lower staggered installations, heating board is separated into several thermals treatment zone with heating container, cold water flows into from water inlet pipe, become hot water after turning round heating through each thermal treatment zone successively, flow out from outlet pipe.
The porch of above-mentioned heating container is provided with water-control switch.
The inwall of above-mentioned heating container is provided with temperature detect switch (TDS).
Above-mentioned temperature regulating switch adopts many grades of change over switches.
Also be provided with electromotion pilot lamp and relay indicating light on the above-mentioned shell.
Also be provided with earth leakage circuit-breaker on the above-mentioned base plate.
Compared with prior art, the utility model has been broken the tradition that adopts metal sleeve to do heater element, has a following distinct advantages:
(1). heating is fast, efficiency is high: the utility model adopts the high-performance silicon nitride ceramic material as heater, can guarantee in 5 seconds, to go out hot water, also can use continuously, need preheating, existing immediately heating water heater to go out long deficiency of hot water time thereby remedied traditional storage-type electric water heater.In addition, measure according to related detection department, capacity usage ratio of the present utility model has substantially exceeded the level of like product more than 95%.
(2) compact conformation, volume are small and exquisite: the heating board in the utility model heating container adopts upper and lower staggered mounting means, current unidirectional revolution in heating container is fully heated, and heating plate adopts silicon nitride ceramic material, its heat-transfer area is big, rate of heat transfer is exceedingly fast, make current in short flow process, can obtain a large amount of heats, therefore, volume of the present utility model can design very for a short time, generally speaking, its volume have only present heat storage type water heater 1/20, immediately heating water heater about 1/5.
(3) safe and reliable: heating board of the present utility model has high temperature resistant, corrosion-resistant, non-conductive, non-scaling, advantages such as long-life, high strength, and it also is provided with water-control switch, temperature detect switch (TDS), earth leakage circuit-breaker, makes the utility model more safe and reliable.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cutaway view of the present utility model.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model comprises panel 1, base plate 2, heating container 3, temperature regulating switch 4, auxiliary relay 5, and after the electric heater energising, the yellow indicator lamp 6A that is installed on the shell 1 is earlier bright, informs the on of user's power supply.The tube valve of fetching boiling water, current flow into from water inlet pipe 3C, and water-control switch 3E opens automatically.Water-control switch is connected auxiliary relay 5, and the red led 6B on the shell 1 is bright, and silicon nitride heat generating body 3A begins heating.Heating board revolution, the heating in each thermal treatment zone 3B successively of the upper and lower staggered installation that current are provided with in the container along heating, heat up, flow out from outlet pipe 3D.General leaving water temperature can be at former basic water temperature rising 45 degree, and too high in order to prevent water temperature, this product is provided with temperature detect switch (TDS) 3F, and water temperature is controlled in the design temperature scope effectively, has stopped the danger that the too high generation of water temperature is scalded.For adapt to throughout the year climate change and the weather conditions of different regions, 4: the first grades of the temperature regulating switch that the utility model is provided with three kinds of temperature heat up 15 ℃ 1700～2000W, second retaining heats up 30 ℃, 3000～3500W, third gear heats up 45 ℃, 5000W.In order to prevent to cause the heating board dry combustion method because of cutting off the water supply, the accident that meets accident, the novel water-control switch 3E that also has been equipped with of the utility model, the automatic energized of water flowing is cut off the water supply and is cut off the electricity supply automatically.In addition, the utility model also is provided with earth leakage circuit-breaker 7, and it can guarantee to cut off the electricity supply immediately when any one parts breaks down the electric leakage of generation trace, has guaranteed the security reliability of electric heater.
