Technical background
Continuous development along with the closed electrical water heater industry, the closed electrical water heater product is constantly weeded out the old and bring forth the new, and is also more and more higher to the requirement of electric heater, requires not only that electric heater capacity is big, volume is little, and require the shape of electric heater changeable, can adapt to the demand of special closed electrical water heater.Some closed electrical water heater small product size are done littler and littler, and electric heater not only comprises the electric heating function element, and also need possess the necessary structure of closed electrical water heater product, as bring structures such as water pipe and drainpipe into.The water inlet pipe of conventional electric heating device and outlet pipe all are mounted on the inner bag, water inlet pipe is installed in the bottom of inner bag, mounting flange in the middle of the inner bag bottom, electrothermal tube is installed on the flange, the temperature-detecting device of control water temperature is installed in the inner bag and is positioned on the electrothermal tube, the electric heater of this structure, when the less but electrothermal tube power of inner bag volume is big again, in order to reduce the surface thermal load of electrothermal tube, improve the service life of electrothermal tube, just must improve the surface area of electrothermal tube, but because the sectional area of inner bag is fixed, when water inlet pipe is installed in the bottom of inner bag, will dwindle the area of flange, make the electrothermal tube limited amount that is installed on the flange, the length that can only increase electrothermal tube reduces the surface thermal load of electrothermal tube, so, the hot water volume in the inner bag will be reduced on the upper side in the installation site of temperature-detecting device.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of requirement that reduces production technology is provided, and can guarantee the electric heater of the new structure in electrothermal tube service life again.
The technical solution of the utility model is: a kind of electric heater of new structure, comprise inner bag (1), be installed in water inlet pipe (2) on the inner bag (1), the temperature-detecting device (6) of drainpipe (3), flange (4), electrothermal tube (5) and control water temperature, flange (4) sealing is installed in the bottom of inner bag (1), electrothermal tube (5) is installed on the flange (4), temperature-detecting device (6) is installed on the inner bag (1) of electrothermal tube (5) top, it is characterized in that: described water inlet pipe (2) sealing is installed on the flange (4).
Described electrothermal tube (5), water inlet pipe (2) are welded on the flange (4).
Described inner bag (1) has more than two, and the bottom of each inner bag 1 and top interconnect by communicating pipe (8) respectively.
Described drainpipe (3) is installed on the flange (4), and the inner extends up to the upper end of inner bag (1).
Described drainpipe (3) is installed in the top of inner bag.
The outer end of described water inlet pipe (2), drainpipe (3) is provided with pipe joint (7) respectively.
Described electrothermal tube (5) is the electrothermal tube of stainless steel casing.
Good effect of the present utility model: the water inlet pipe sealing is installed on the flange, be installed in the bottom of inner bag with respect to water inlet pipe, can increase the area of flange, thereby the span that so just can set up electrothermal tube quantity or increase electrothermal tube on flange increases the length of electrothermal tube, realize the heating element heater of same power, the requirement that the unit are thermic load reduces makes the electrothermal tube longer service life.And water inlet pipe changes into and being installed on the flange by being installed in inner bag bottom, simplified product structure design, thereby improved production technology can reduce production costs effectively.
