Abstract

The utility model relates to an electric water heater, which comprises a water inlet heating chamber, a water outlet heating chamber, a temperature controller, and a gear switch. The utility model is characterized in that the water inlet heating chamber and the water outlet heating chamber are connected through a water flow temperature adjuster, the temperature controller and the gear switch are both positioned between the water inlet heating chambers and the water outlet heating chamber, the temperature controller and the gear switch are electrically and respectively connected with a heating tube in the water inlet heating chamber and the water outlet heating chamber, and a water-electricity isolating switch is arranged between the lower parts of the water inlet heating chamber and the water outlet heating chamber. The utility model has the advantages that the electric water heater can replace the prior similar products by adopting the above technical proposal, the electric water heater is powered on as soon as water is filled, the electricity is cut off as soon as water is stopped, the boiling without water is prevented, the electronic controlling circuit is completely omitted, the size is smaller, and the cost is lower.

Description

Electric heater

Technical field:

The utility model relates to technical field of water heaters, refers in particular to a kind of electric heater.

Background technology:

Existing electric heater on the market is various owing to electronic circuit, and cost is higher, the fault rate height, and bulky, be difficult for installing.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of volume is little, cost is low, the electric heater of anti-dry.

For achieving the above object, the technical scheme that the utility model provides is: include into water heating storehouse and water outlet heating storehouse, temperature controller, driving switch, it is characterized in that: water inlet heating storehouse is connected by the current thermosistor with water outlet heating storehouse is middle, temperature controller and driving switch are all between two heating storehouses, temperature controller and driving switch are electrically connected with the heat-generating pipe of two heatings in the storehouses respectively, and two generate heat is equipped with the water power isolating switch between the bottom in storehouses.

The utility model can replace existing like product after adopting technique scheme, and it can accomplish that water flowing then switches on, and the then outage of cutting off the water prevents dry combustion method, omit electronic control circuit fully, and volume is less, and cost is lower.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further, see shown in the accompanying drawing 1, preferred embodiment of the present utility model mainly includes into water heating storehouse 1 and water outlet heating storehouse 2, temperature controller 3, driving switch 5, water inlet heating storehouse 1 is connected by current thermosistor 4 with 2 centres, water outlet heating storehouse, temperature controller 3 and driving switch 5 are all between two heating storehouses, temperature controller 3 and driving switch 5 are electrically connected with the heat-generating pipe of two heatings in the storehouses respectively, and two generate heat is equipped with water power isolating switch 6 between the bottom in storehouses.

Operation principle of the present utility model is: when water flows out from water power isolating switch 6 with the pressure more than the 0.002Mpa, hot water just produces hot water by driving switch 5 selected power, adjust accurate water temperature with current thermosistor 4, when the water heating of certain gear surpasses 65 ℃, the switch of temperature controller 3 will open circuit and make these shelves stop heating, temperature detect switch (TDS) conducting more again when water temperature drops to a certain degree recovers heating work, accomplishes anti-overtemperature and anti-dry function thus.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
