Abstract
The utility model discloses a dry burning-resistant temperature controller assembly structure for an internal heating type tubular electric heating element. The dry burning-resistant temperature controller assembly structure mainly comprises a shell 1, the tubular electric heating element 2, a limiting ring 3, a screw sealing ring 4, a screw, a temperature controller 6 and a temperature controller sealing ring 7, wherein the temperature controller 6 controls the surface temperature of the tubular electric heating element 2 within a set range, thereby ensuring using safety in a dry burning or abnormal state. The dry burning-resistant temperature controller assembly structure for the internal heating type tubular electric heating element has a compact and simple structure, and cost is minimized.
Description
Technical field
The utility model relates to the electrothermal tube anti-dry temperature control assembly structure of internal heat type, and this anti-dry temperature control assembly structure is applicable on the Instant heating type boiling water heater.
Background technology
For prevent that Instant heating type boiling water heater from continuing to be heated under anhydrous state, cause accident, the electric heater unit that is used for Instant heating type boiling water heater all needs the anti-dry function.General Instant heating type heating products all is an internal heat type, and electrothermal tube directly is installed in the water, does not generally all have anti-dry burning device or the anti-dry temperature control is installed on a support or the conducting strip, can not accurately and timely measure the actual temperature on electrothermal tube surface.
To existing Instant heating type water-heating device, its most of product does not all have the anti-dry structure, when this hot-water heating system generation dry combustion method; Housing does not have residual water, and electrothermal tube is in dry-fire condition, and surface temperature sharply heats up; Potential safety hazards such as the blast of meeting generation electrothermal tube, other parts burn out.
Summary of the invention
The utility model is according to the weak point of above-mentioned prior art, propose a kind of simple in structure, guarantee housing under anhydrous or abnormal condition, the electrothermal tube anti-dry temperature control assembly structure of the internal heat type that can not work on.
The utility model purpose is realized by following technical scheme:
The described anti-dry temperature control of the utility model assembly structure is characterized in that; This assembly structure is made up of housing 1, electrothermal tube 2, spacing collar 3, screw sealing ring 4, screw 5, temperature control 6, temperature control sealing ring 7; Temperature control 6 is arranged at housing 1 one sides, and the temperature control bottom directly contacts with electrothermal tube 2 surfaces, is added with screw 5 at temperature control 6 two ends and fixes; Screw 5 is placed in the spacing collar 3; Spacing collar 3 can make electrothermal tube 2 keep certain distance with housing 1 and prevent that effectively screw 5 from directly contacting with electrothermal tube 2 surfaces, is with temperature control sealing ring 7 and screw sealing ring 4 respectively at temperature control 6 and screw 5, can prevent that effectively sealing flows out from the gap; Be under dry combustion method or the abnormal condition at electrothermal tube, the electrothermal tube surface temperature can sharply rise, and when the electrothermal tube surface temperature reached certain value, temperature control was started working, and temperature control will be broken off, and electrothermal tube quits work.
The utility model has the advantages that: the putting position of appropriate design temperature control, make that when the electrothermal tube surface temperature surpassed preset temperature, the anti-dry temperature control began action, circuit breaks off, and electrothermal tube quits work.The utility model device, compact conformation and simple can be realized minimization of cost, guarantees the security of using.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model structural representation;
Among the figure, 1-housing, 2-electrothermal tube, 3-spacing collar, 4-screw sealing ring, 5-screw, 6-temperature control, 7-temperature control sealing ring.
The specific embodiment
Like accompanying drawing 1 signal; The electrothermal tube anti-dry temperature control assembly structure of the described internal heat type of the utility model mainly is made up of housing 1, electrothermal tube 2, spacing collar 3, screw sealing ring 4, screw 5, temperature control 6, temperature control sealing ring 7, it is characterized in that in housing one side the anti-dry temperature control being installed; The temperature control bottom directly contacts with electrothermal tube; Be added with screw 5 at temperature control 6 two ends fixing, and screw 5 is placed in the spacing collar 3, and spacing collar 3 can make electrothermal tube 2 keep certain distance with housing 1 and prevent that effectively screw 5 from directly contacting with electrothermal tube 2 surfaces; Be with temperature control sealing ring 7 and screw sealing ring 4 respectively at temperature control 6 and screw 5, can prevent that effectively sealing flows out from the gap.The electrothermal tube of this internal heat type occurs under dry combustion method or the abnormal condition in use, and the surface temperature of electrothermal tube will sharply rise, and when the electrothermal tube surface temperature reached certain value, temperature control will be broken off, thereby has avoided the various adverse consequences that cause therefrom.
The course of work of the utility model device is; Through anti-dry temperature control 6 being installed in Instant heating type boiling water heater housing one side; Temperature control 6 bottoms are installed on the surface of electrothermal tube 2, and the bottom directly contacts with electrothermal tube, is provided with two hold-down screws 5 at temperature control 6 two ends; Temperature control and screw are with temperature control sealing ring 7 and screw sealing ring 4 respectively, can in water heating process, from the gap, flow out by anti-effectively sealing.This anti-dry temperature control 6 is in normal heating water process, and temperature control cuts little ice, but electrothermal tube 2 occurs under dry combustion method or abnormal condition; Temperature control 6 is started working and can be cut off circuit in dry combustion method in 10 seconds; Electrothermal tube 2 stops heating, reduces to just often when pipe table temperature, and electrothermal tube begins normal heating work; So circulation, the purpose that can protect electrothermal tube and other parts not to be damaged effectively.
Though below design and instance according to the utility model purpose have been done to elaborate with reference to accompanying drawing; But those of ordinary skills can recognize; Under the precondition that does not break away from the claim limited range; Still can make various improvement and conversion to the utility model, and this improvement and conversion still should belong to the protection domain of the utility model.
