Abstract
A quartz glass electrical heated tube overheating protection device for a fast boiling water machine comprises a quartz glass electrical heated tube, which is externally connected with an AC power source L-electrode connecting base in one end and connected with am AC power source N-electrode connecting base in the other end. A thermal protector is arranged in the AC power source L-electrode, and a thermal fuse is provided in the AC power source N-electrode in the other end of the quartz glass tube. Overheating protection within two set temperature ranges are utilized, the thermal protector in the upper part is off when reaching the temperature within the first temperature range, and the thermal protector restarts to work if the temperature falls down for temperature protection function. If the thermal protector is not off in malfunction, the water in the heater will be dry out fast, after the temperature of the thermal tube AC power source N-electrode reaches to the temperature within the set second temperature range, the fuse in the thermal protective tube will be off so as to prevent destroy of heater or prevent fire disaster in order to achieve the overheating protection function.
Description
Technical field
The utility model relates to the electric heater overtemperature protection system, particularly a kind of overtemperature protection system of quartz glass electrothermal tube.
Background technology
The present more employing efficient energy-saving of rapid boiling water machine quartz glass electrothermal tube; but in the overtemperature protection problem of quartz glass electrothermal tube good mode preferably not also; more commonly Thermal Cutoffs is arranged near the electrothermal tube; Thermal Cutoffs receives the thermal radiation temperature of electrothermal tube; in case surpassing set temperature will cut off the electricity supply; this mode is reliable and stable not; very slow because so the insulating sleeve response speed will be overlapped in Thermal Cutoffs outside, be not suitable for doing the overtemperature protection system of the quartz glass electrothermal tube of Fast Heating boiling water.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can react fast overtemperature protection system to the quartz glass electrothermal tube, reaches that response speed is fast, temperature controlling range is accurate, simple in structure, purpose that cost is low.
The utility model solves its technical problem and takes following technical scheme to realize:
Rapid boiling water machine quartz glass electrothermal tube overtemperature protection system; it comprises the quartz glass electrothermal tube; at quartz glass tube one end external AC power supply L utmost point Connection Block, at quartz glass tube other end connection AC power N utmost point Connection Block; its feature is established a temperature protector at described AC power L utmost point Connection Block, establishes a Thermal Cutoffs at described quartz glass tube other end AC power N utmost point Connection Block.
Described quartz glass electrothermal tube comprises electric wire tube or electric heating membrane pipe.
Described quartz glass electrothermal tube comprises quartz glass electrothermal tube arranged side by side more than two or two.
Described two ends peripheral circuit Connection Block between the quartz glass electrothermal tube arranged side by side more than two or two; establish AC power L utmost point Connection Block at described two quartz glass electrothermal tube one ends; establish a temperature protector at described AC power L utmost point Connection Block; establish AC power N utmost point Connection Block at described two quartz glass electrothermal tube other ends, establish a Thermal Cutoffs at described AC power N utmost point Connection Block.
The beneficial effects of the utility model; be the temperature-sensitive protection is established respectively at quartz glass electrothermal tube two ends; adopt the overtemperature protection of two design temperature sections; boiled water machine not during lack of water owing to there is in time the dispel the heat temperature of heating tube AC power L utmost point Connection Block and heating tube AC power N utmost point Connection Block of water the phenomenon that significantly raises can not occur; in case the temperature of the upper end of heater local lack of water heating tube AC power L utmost point Connection Block will raise; the temperature protector that reaches upper end when setting the first temperature section temperature disconnects; drop in temperature can restart, and plays the temperature protection effect.If breaking down, temperature protector can not disconnect; the water of heater dryouies rapidly; fuse disconnects when the temperature of heating tube AC power N utmost point Connection Block reaches the second temperature section temperature of setting, in the temperature safety tube; prevent from burning heater or avoid fire to occur, thereby played superheat protecting function.

Fig. 2 is electrothermal membrane type quartz glass electrothermal tube overtemperature protection system structure chart.
Fig. 3 is two quartz glass electrothermal tube overtemperature protection system structure charts.
The specific embodiment
By reference to the accompanying drawings a kind of embodiment of the utility model is further described.
As shown in Figure 1; overtemperature protection system for the rapid boiling water machine quartz glass electrothermal tube of electric-heating-wire-heating comprises temperature protector 1, circuit brace 2, AC power L utmost point power line 3, AC power L utmost point Connection Block 4, quartz glass electrothermal tube 5, AC power N utmost point Connection Block 6, Thermal Cutoffs 7, Thermal Cutoffs package lead 8, fixed card 9 and Thermal Cutoffs lead 10.
Be illustrated in figure 2 as the outer Electric radiant Heating Film 12 that stick of quartz glass tube 5, with the figure difference be that heating wire 11 is replaced by Electric radiant Heating Film 12, other structures are identical with Fig. 1, needn't repeat.
As shown in Figure 3; temperature protector 1 is fixed on the AC power L utmost point Connection Block 4 of quartz glass electrothermal tube 5 upper ends; terminals of temperature protector 1 are connected on the AC power L utmost point Connection Block 4 by circuit brace 2, and another terminals connect AC power L utmost point power line 3.The shell of Thermal Cutoffs 7 is fixed on the AC power N utmost point Connection Block 6 of electrothermal tube 5 lower ends with fixed card 9, one end is that Thermal Cutoffs package lead 8 also is connected on the AC power N utmost point Connection Block 6, the other end is that Thermal Cutoffs lead 10 is connected to AC power N and extremely goes up
Present embodiment has adopted the overtemperature protection of two temperatures section; quartz glass electrothermal tube 5 is not normally during lack of water; owing to have the timely heat radiation heating tube AC power L electrode Connection Block 4 of water and the temperature of electrothermal tube AC power N utmost point Connection Block 6 the significantly phenomenon of rising can not occur; in case the temperature of the upper end of heater local lack of water electrothermal tube AC power L utmost point Connection Block 4 will raise rapidly; reach temperature protector 1 disconnection when setting the first temperature section temperature; can restart behind the drop in temperature, play the temperature protection effect.If breaking down, temperature protector 1 do not disconnect; the water of electrothermal tube 5 inside dryouies rapidly; when the temperature of electrothermal tube AC power L utmost point Connection Block 6 reaches the second temperature section temperature of setting, Thermal Cutoffs 7 permanent disconnections; Thermal Cutoffs 7 is expendable; prevent from burning heater or avoid fire to occur, thereby played superheat protecting function.
