Abstract
A heating cup with water inlet and outlet bidirectional electricity-proof wall comprises a cup cover, a cup body, a heating wire component, a cup base and a temperature sensor. The upper end of the cup cover is provided with a water outlet earth terminal, the cup cover and the cup base are fixed at upper and lower sides of the cup body by screw nails, nut pads and square flanges. An upper seal ring is provided between the cup cover and the cup body, a lower seal ring is provided between the cup base and the cup body. The cup body is composed of a plurality of cavities and comprises a heating wire cavity, a water inlet electricity-proof wall cavity, a water outlet electricity-proof wall cavity, a water inlet cavity and a water outlet cavity. A baffle is packaged outside the heating wire component, the upper end of the baffle is embedded with a ceramic chip, the heating wire component is positioned in the heating wire cavity, a temperature sensor is fixed on the cup base. The utility model has advantages that not only the pressing resistance and seal abilities of an electric water heater can be ensured by heating the integral arranging of an inner container and the electricity-proof wall, but also the skill design of heating a plurality of cavities of the inner container and naked wire heating elements as heating wires can greatly improve the heating efficiency and safety performance.
Description
Technical field: the utility model relates to a kind of water heater heating cup, and especially a kind of heating cup of bringing the water outlet two-way anti-electric shock wall into is mainly used in the water heater industry.
Background technology: the heating cup is the core component of water heater, but often exists electric leakage hidden danger.
Summary of the invention: at above-mentioned the deficiencies in the prior art, the utility model provides the anti-creeping heating cup of bringing the water outlet two-way anti-electric shock wall into.
For achieving the above object, the technical solution adopted in the utility model is: bring the heating cup of water outlet two-way anti-electric shock wall into, comprise bowl cover, cup body, heating wire assembly, cup and temperature sensor.The upper end of bowl cover is provided with the delivery port ground terminal, and bowl cover and cup are fixed on the both sides up and down of glass body by screw, nut shim and square flange.Be provided with sealing ring between bowl cover and cup body.Be provided with lower seal between cup and cup body.The cup body is made up of a plurality of cavitys, comprises the heating wire chamber, and electric wall chamber is prevented in entry, and electric wall chamber is prevented in water outlet, goes into water cavity and water chamber.The heating wire assembly is wrapped with dividing plate.The upper end of dividing plate is embedded with potsherd.The heating wire assembly is in the heating wire chamber.Temperature sensor is fixed on the cup.Cup is provided with thermal cut-off on one's body.
Advantage of the present utility model is to heat inner bag and prevents being wholely set of electric wall, not only guaranteed the withstand voltage and sealability of this electric heater, and heating inner bag a plurality of cavitys, naked silk heating element heater the efficiency of heating surface and security performance have been improved greatly as the ingenious design of heater strip.

The specific embodiment:
As shown in Figure 1-Figure 3: bring the heating cup of water outlet two-way anti-electric shock wall into, comprise bowl cover 2, cup body 4, heating wire assembly 5, cup 9.The upper end of bowl cover 2 is provided with delivery port ground terminal 1, and bowl cover 2 and cup 9 are fixed on the both sides up and down of glass body 4 by screw 11, nut shim 12 and square flange 13.Bowl cover 2 and 4 of bodies of cup are provided with sealing ring 3.Cup 9 and 4 of bodies of cup are provided with lower seal 8.Cup body 4 is made up of a plurality of cavitys, comprises heating wire chamber 14, and electric wall chamber 15 is prevented in entry, and electric wall chamber 16 is prevented in water outlet, goes into water cavity 17 and water chamber 18.Heating wire assembly 5 is wrapped with dividing plate 7.The upper end of dividing plate 7 is embedded with potsherd 6.Heating wire assembly 5 is in the heating wire chamber 14.Temperature sensor 10 is fixed on the cup 9.Cup is provided with thermal cut-off 30, and when the heating wire dry combustion method, thermal cut-off 30 detects surface temperature, and defencive function has fused.
As shown in Figure 4: the water pipe of anti-electric wall is made up of anti-electric wall water pipe 19 of water inlet and the anti-electric wall water pipe 20 of water outlet.
As shown in Figure 5: bowl cover 2 upper ends are provided with delivery port 21, and the cup lower end is provided with water inlet 22.Cup body 4 is provided with tapping screw 23, fixes with the water heater drain pan.
Operation principle: anti-electric wall module (being water resistance decay isolation method) is exactly the resistance that utilized water itself to be had (should be no more than 1300 Ω .cm as GB regulation running water resistivity 15 ℃ the time), the conductive path of material (insulating materials), caliber and restriction water by anti-electric wall module carries out the Leakage Current decay, forms the anti-electric wall of safety.When electric heater energising work, even the water of heating cup has, also can isolate in water route by anti-electric wall module, the atomic weak current (national standard is 0.25mA/kw) that maximum voltage (being equivalent to 12V) that makes the water heater water side reach human body to bear and 0.02mA/kw are following is guaranteed the safety of the person.
