Description
Technical field
The utility model relates to water heater, more specifically, relates to the spiral shell hair style heating tube that is arranged in the water heater.
Background technology
In the present water heater that spiral shell hair style heating tube is installed, mainly be provided with magnesium rod and stainless heating tube in the enamel inner container of water heater.The connected mode of heating tube and enamel inner container mainly contains two kinds.A kind of connected mode be heating tube with enamel inner container between on-insulated the connection, in this connected mode, the magnesium rod directly is fixed on the inner bag, so is complete conducting between magnesium rod and the heating tube.Because the stainless steel body of heating tube directly exposes in the water of enamel inner container; And because the bare area of heating tube body is bigger; Magnesium rod meeting priority protection heating tube; This causes the magnesium rod too fast because of electrochemical reaction consumes, and has shortened the useful life of magnesium rod, causes the magnesium rod can not well protect enamel inner container.Another kind of connected mode be heating tube with inner bag between fully insulation be connected; Though this connected mode has prolonged the useful life of magnesium rod; But because the stainless steel body does not have the protection of magnesium rod, phenomenons such as spot corrosion take place in its stainless steel surfaces easily, cause the heating tube corrosion to be leaked.
Therefore, need a kind of water heater, can either protect the heating tube body, can protect enamel inner container effectively again.
The utility model content
To the one or more problems that exist in the correlation technique, the purpose of the utility model is a kind of spiral shell hair style heating tube is provided and the water heater that is provided with this spiral shell hair style heating tube.Through this spiral shell hair style heating tube is set in water heater, can either protect the heating tube body not to be corroded, can prolong the useful life of magnesium rod again.
For realizing above-mentioned purpose, according to an aspect of the utility model, a kind of spiral shell hair style heating tube is provided, the resistance that it comprises spiral shell head, body and is connected spiral shell head and body, wherein:
The spiral shell headgear is located at the lead end of heating tube, and is provided with insulating part between spiral shell head and the body.
Preferably, resistance is embedded in the insulating part between spiral shell head and the body.
Preferably, resistance is 500-600 ohm.
According to the utility model on the other hand, a kind of water heater is provided, this water heater comprises above-mentioned any spiral shell hair style heating tube.
Preferably, water heater also comprises magnesium rod and enamel inner container, wherein the magnesium rod be arranged in the enamel inner container and with its conducting, the spiral shell head of spiral shell hair style heating tube be connected with enamel inner container and with its conducting, and body is arranged in the enamel inner container.
Preferably, between the spiral shell head of spiral shell hair style heating tube and enamel inner container, be provided with holder, holder connects spiral shell head and enamel inner container, and the spiral shell head passes through the holder conducting with enamel inner container.
Preferably, be provided with at least two magnesium rods and spiral shell hair style heating tube in the enamel inner container.
Through above-mentioned at least one technical scheme,, make both not exclusively insulation, not exclusively conductings again between spiral shell head and the body between the spiral shell head of heating tube and body through the resistance of certain resistance is set according to the spiral shell hair style heating tube of the utility model.Because spiral shell head and enamel inner container conducting, thereby make both not exclusively insulation between heating tube and the enamel inner container, also incomplete conducting, but the resistance conducting through certain resistance.This can reduce the current sinking of magnesium rod, reduces the depletion rate of magnesium rod, prolongs the useful life of magnesium rod, thereby effectively protects enamel inner container.Can make the certain electric current of maintenance between heating tube and the enamel inner container again, thereby effectively protect heating tube.Therefore, spiral shell hair style heating tube according to the present invention can prolong the useful life of magnesium rod, protects the enamel inner container of water heater effectively, can realize protection to a certain degree to heating tube again.
