The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Shown in Fig. 1,2,3,4, the utility model comprises tank body 1 and chassis 6, tank body 1 is made for plastic material, its top seal, and the lower end is uncovered, uncovered outer, lower end is provided with flange 16, fixedly connected by screw in this flange 16 and chassis 6, the junction is provided with sealing ring 3, and a heat-generating pipe 4 is installed in described chassis 6, the tube wall of this heat-generating pipe 4 contacts with chassis 6, and the opposite side that is positioned at this contact site on the chassis 6 is installed an automatic anti-dry heating temperature controller 8.
In the present embodiment, above-mentioned tank body 1 top is respectively equipped with outlet pipe 11 and blast pipe 12, be provided with water inlet pipe 15 in the bottom of tank body 1, flange 16 is provided with limited post 17, and spacing hole 31 on limited post 17 and the sealing ring 3 and the spacing hole 63 on the chassis 6 match; For described sealing ring 3 is better located, it is provided with projection 32, can cooperate with the stopper slot 18 on the flange 16; Above described water inlet pipe 15, be provided with a groove 14, one heating temperature control device 2 is installed in this groove 14 is used for prosecution heat jar interior water temperature, these heating temperature control device 2 tops are provided with water fender 13, and current advance heating temperature control device 2 and perils such as electric leakage occur in the time of can preventing to leak; The outlet of described water inlet pipe 15 also connects an aqueduct 19 that water is flowed downward, and the cold water that enters is flowed downward, and can improve the outlet capacity that heats of heat jar.
It is pyrotoxin that the utility model adopts heat-generating pipe 4, and this heat-generating pipe 4 adopts one to enclose heat-generating pipe, and level is installed in the chassis 6, and its mouth of pipe 41 is connected with locating hole 61 on 6 sidewalls of chassis, and tube wall contacts with 6 bottoms, chassis.For the tube wall that makes heat-generating pipe 4 closely contacts and not loosening with chassis 6, so a lock bracket 5 is set, this support 5 is set on the heat-generating pipe 4, and support 5 edges and chassis 6 weld together.In heat-generating pipe 4 and 6 contacts site, chassis, the opposite side that is positioned at chassis 6 also is connected with an automatic anti-dry heating temperature controller 8, and this temperature controller 8 is installed on the chassis 6 by temperature controller support 7; In order to improve security performance, on this temperature controller support 7, also be provided with a manual anti-dry heating temperature controller 9.
