Summary of the invention
The technical problems to be solved in the utility model provides a kind of electric heater of anti-dry, can increase the heating surface (area) (HS of current, has than the higher efficiency of heating surface.
In order to solve the problems of the technologies described above, the electric heater of a kind of anti-dry of the present utility model, comprise upper pedestal, lower base, be arranged on, slot-shaped current electric heater between the lower base, be installed in the outlet pipe on the upper pedestal, and be arranged on the water inlet pipe of lower base bottom, the outbound course of water inlet pipe is provided with impeller, the both sides of lower base bottom are provided with the Photoelectric Detection head of measuring wheel speed, described slot-shaped current electric heater is formed by stacking by several heat-generating units, described heat-generating units comprises clamping ring, on this clamping ring supporting slice is installed, be equipped with the heating sheet on the supporting slice, described supporting slice and heating have on the sheet be bonded with each other first, second limbers, clamping ring are provided with some projectioies, have and first of this projection corresponding matching on described supporting slice and the heating sheet, second installing hole, the both sides of described slot-shaped current electric heater are respectively arranged with fastening arm, and the lower end of this fastening arm and lower base fasten, and the upper end is equipped with the screw that described upper pedestal is compressed.
As improvement of the technical scheme, the top of described upper pedestal is provided with the cushion block that described screw is formed supporting.
As further improvement in the technical proposal, exist at interval between the top outer rim of described impeller and the end face of described water inlet pipe.
The beneficial effects of the utility model are: the heat-generating units of the electric heater of this anti-dry can overcome screw and connect the problem that exists owing to adopt the combinations thereof structure, can increase the heating surface (area) (HS of current, improves the efficiency of heating surface of electric heater.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a surface structure schematic diagram of the present utility model;
Fig. 2 is a part-structure exploded view of the present utility model;
Fig. 3 is STRUCTURE DECOMPOSITION figure of the present utility model.
The specific embodiment
Referring to figs. 1 through Fig. 3, the electric heater of a kind of anti-dry of the present utility model, comprise upper pedestal 1, lower base 2, be arranged on, lower base 1, slot-shaped current electric heater 3 between 2, be installed in the outlet pipe 4 on the upper pedestal 1, and be arranged on the water inlet pipe 5 of lower base 2 bottoms, the outbound course of water inlet pipe 5 is provided with impeller 6, the both sides of lower base 2 bottoms are provided with the Photoelectric Detection 7 of measuring impeller 6 rotating speeds, described slot-shaped current electric heater 3 is formed by stacking by several heat-generating units, described heat-generating units comprises clamping ring 31, on this clamping ring 31 supporting slice 32 is installed, be equipped with heating sheet 33 on the supporting slice 32, have on described supporting slice 32 and the heating sheet 33 be bonded with each other first, second limbers 321,331, clamping ring 31 is provided with some protruding 311, have and first of this projection 311 corresponding matching on described supporting slice 32 and the heating sheet 33, second installing hole 322, the both sides of described slot-shaped current electric heater 3 are respectively arranged with fastening arm 8, the lower end of this fastening arm 8 and lower base 2 fasten, and the upper end is equipped with the screw 9 that described upper pedestal 1 is compressed.The heat-generating units of the electric heater of this anti-dry can overcome screw and connect the problem that exists owing to adopt the combinations thereof structure, can increase current and the heating surface (area) (HS that the heating sheet contacts, and improves the efficiency of heating surface of electric heater.On the other hand, because heating sheet 33 forms a flat rectangular cavity with clamping ring 31, its surface area ratio has the surface area of the circular pipe of same sectional area and wants big, so its heating surface (area) (HS is also bigger, can further improve the efficiency of heating surface of electric heater.
The top of described upper pedestal 1 is provided with the cushion block 10 that described screw 9 is formed supporting, avoids the extruding of screw that upper pedestal 1 is caused damage.
Exist between the top outer rim of described impeller 6 and the end face of described water inlet pipe 5 at interval, make the position of impeller 6 low with respect to the position in the utility model patent of first to file, adopt this structure, if there is air to enter water inlet pipe 5, air can pass through from above-mentioned interval, active force to impeller 6 is less, be difficult to promote wheel rotation, the rotating speed that the Photoelectric Detection head detects impeller is lower than to be set numerical value and just controls electric heater and stop heating, even the flow velocity of air is bigger, impeller 6 is promoted, because the refractive index difference of empty G﹠W is bigger, thereby the Photoelectric Detection head also can detect the variation control electric heater of light stops heating, prevents that dry combustion method from meeting accident.
