Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figure 1 to Figure 3, the electric hot-water bag anti-dry electro-heat equipment of the improvement in the present embodiment comprises insulating support 1, heating pipe support 2 and heat-generating pipe 3.Wherein insulating support 1 is provided with power connector 4, temperature controller 5 and the second thermal cut-off 7, heating pipe support 2 adopts insulator and fixes with insulating support 1, insulating support 1 both can be fixed on the outside of heating pipe support 2, also can be fixed on the inner side of heating pipe support 2.Heat-generating pipe 3 and the first thermal cut-off 6, first thermal cut-off 6 are installed in the inside of heating pipe support 2 can directly contact fixing with heat-generating pipe 3 or be fixed by heat carrier and heat-generating pipe 3.
Heat-generating pipe 3 in the present embodiment adopts U-shaped, and heating pipe support 2 has the U-shaped installation portion of inserting for U-shaped heat-generating pipe 3.First thermal cut-off 6 has three and is positioned at described U-shaped installation portion, and one of them first thermal cut-off 6 is arranged on the bottom of U-shaped heat-generating pipe 3, and another two the first thermal cut-ofves 6 are arranged on the two ends of U-shaped heat-generating pipe 3 respectively.After first thermal cut-off 6 adopts above-mentioned mounting structure, in bag, liquid is less, even if heat-generating pipe run-off the straight and cause heat-generating pipe local expose liquid formed dry combustion method, also always there is corresponding the first thermal cut-off being exposed to liquid side can cut off the electricity supply in time to make hot water bag stop heating, thus improve safety in utilization.
As shown in Figure 4, microswitch 10, temperature controller 5, heat-generating pipe 3, first thermal cut-off 6, second thermal cut-off 7 are connected on the series circuit by Power supply, resistance 8 and display lamp 9 are connected mutually, resistance 8 after series connection and display lamp 9 are in series with temperature controller 5, and be in parallel with the series circuit that heat-generating pipe 3 and the first thermal cut-off 6 are formed, resistance and display lamp form indicating circuit, are used to refer to the charged state of electric hot-water bag, and microswitch 10 is used for controlling the break-make of series circuit.The minimum temperature that the ceiling temperature that temperature controller 5 sets sets lower than the first thermal cut-off 6 and the second thermal cut-off 7, as long as namely heating-up temperature is no more than the ceiling temperature that temperature controller 5 sets, temperature controller 5, first thermal cut-off 6 and the second thermal cut-off 7 all can make series circuit conducting, now, display lamp 9 is lighted, and the charging of prompting electric hot-water bag is normal.When heating-up temperature exceedes the ceiling temperature of temperature controller 5 setting; temperature controller 5 is by dump; display lamp 9 extinguishes; prompting charge fault; when heating-up temperature exceedes the ceiling temperature of temperature controller 5 setting and temperature controller 5 lost efficacy, substitute temperature controller 5 by the second thermal cut-off 7 and proceed temperature protection.
As shown in Figure 5, eliminate the second thermal cut-off 7 compared with the circuit diagram of Fig. 4, remaining circuit structure is identical, is not described in detail at this.
Operation principle of the present utility model is as follows: switch on power, by heat-generating pipe 3 to the liquid heat in bag, in this heating process, for controlling optimum temperature, a ceiling temperature is preset by temperature controller 5, when the temperature of liquid heated exceedes the ceiling temperature of temperature controller 5 setting, by temperature controller 5 by dump, no longer heat.And just in case when temperature controller 5 is malfunctioning; the heating-up temperature of electric hot-water bag then can be controlled by the second thermal cut-off 7; when heating-up temperature exceedes the design temperature of this second thermal cut-off 7; cut off the electricity supply by the second thermal cut-off 7; stop heating; thus acquisition duplicate protection, improve the safety in utilization of hot water bag.In addition, the first thermal cut-off 6 can automatically disconnect cutting off the electricity supply under heat-generating pipe dry-fire condition, thus makes safety be able to further raising.
The foregoing is only preferred implementation of the present utility model, should be understood that, for those of ordinary skills, do not departing under principle prerequisite of the present utility model, multiple remodeling or improvement can be carried out to this utility model, as long as such as the first thermal cut-off is arranged on the position keeping responding to heat-generating pipe heat with heat-generating pipe, and be not limited to the installation site that the present embodiment provides, such as the first thermal cut-off can be more than one or one, such as can also match in heat-generating pipe outer cladding shape and heat-generating pipe again and there is the water suction overcoat compared with strong absorptive energy, to improve anti-dry effect further, these are all regarded as within protection domain of the present utility model.
