Abstract
The utility model relates to a water heating device, in particular to a safe quick water heater used for bathing, comprising a water tank shell and an electric heater inside the water tank shell, wherein, the electric heater is covered inside a metal hood, is full of water and is separated from the metal hood; water flows through an over flow channel between the metal hood and the water tank shell; insulating oil heated by the electric heater transfers heat to the water in the over flow channel via the metal hood, so as to realize water heating. The utility model is characterized in electric leakage prevention, dry burning prevention, safety and reliability.
Description
Technical field: the utility model relates to a kind of electric heater unit of water, promptly is used to produce the water heater safely and fast of hot water, bath water.
Technical background: in prior art, present fast water heater mainly by bring into, the tank shell of delivery port, the electric heater in the housing constitute.Electric heater directly places heated water, once electric leakage, then housing is charged, causes the user to get an electric shock, and safety can not get guaranteeing.In addition, forget water flowing as various reasons in the use, can burn electric heater when producing dry combustion method, and cause getting an electric shock.
The utility model content: the utility model purpose provides water heater safely and fast anticreep, anti-dry
Technical solution of the present utility model is: safely and fast water heater comprise bring into, the tank shell of delivery port, the electric heater in the housing.Electric heater is fixed on the insulation board, metal cap on the outer mask, and sealing is full of heat conductive insulating liquid is arranged between metal cap and the electric heater, forms water jacket between metal cap and the tank shell.After the energising, electric heater heats iknsulating liquid in it, and heat is delivered to the flowing water of crossing between metal cap and the tank shell by metal cap, reaches heating purposes.
The utility model has the advantages that: anticreep, anti-dry combustion method, safe and reliable.Electric heater is among the iknsulating liquid, and is isolated with metal cap, and as adopting transformer oil, its breakdown voltage is more than 30,000 volts, and the voltage that this electrical equipment normally uses only is 220V, can never leak electricity.In the use, even anhydrous in the water tank, dry combustion method takes place, iknsulating liquid is heated to 100 degrees centigrade also wants a few minutes, temperature detect switch (TDS) outage automatically when high again can prevent to damage electric heater because of dry combustion method.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Description of drawings: Fig. 1 is a structure diagram of the present utility model.
The specific embodiment: referring to Fig. 1, the electric heater of water heater is fixed on the plastic insulation plate 2 safely and fast.Metal cap 3 also is fixed on the insulation board 2, and with electric heater 1 sealing within it, between be full of the also transformer oil 4 (also available machine oil) of heat conduction of insulation.Tank shell 5 is installed in the outside of metal cap 3, forms water jacket 6 in tank shell 5 and between the metal cap 3.Water flows out from delivery port 8 through water jacket 6 from water inlet 7.For ease of transformer oil 4 expanded by heating, communicate with a space 9 outside the oil sump at the oil sump of containing thermal conductive insulator.Electric heater 1 is a flat box body shape, and the nickel filament 10 of many different capacities is installed in it.
The logical running water of going up during use, water flows into from water inlet 7, flows out from delivery port 8 through water jacket 6.Energising back electric heater 1 is with transformer oil 4 heating, and heat is delivered to water jacket 6 through metal cap 3, and with water heating in it, hot water flows out from delivery port 8.For water jacket 6 inner cold waters of flowing through are fully heated, make rough and uneven in surfacely at metal cap appearance and water contact surface, or have fin, or form back-shaped curve runner, or convex-concave runner (all not drawing among the figure), water longshore current road is flowed in order, guarantee even water temperature.
Regulate water temperature by power switch 11,12,13,14 controls.In the transformer oil 4 meeting inflow spaces 9 that expand during heating.Oil in the oil sump can be observed from oily window 15, can in time discover if any oil seepage phenomena, replenishes oil plant.The utility model adopts iknsulating liquid sealed electrical heater technology, can prevent to get an electric shock because of the electric heater electric leakage, thereby safe and reliable, adopt this principle, can be made into various water heaters, shower, electric heater.
Claims (4)
