Abstract
The utility model relates to a temperature control switch for water heaters, which composed of a steam chamber, a shape memory alloy, an elastic rubber sealing ring and a contact point switch. The shape memory alloy which is a screw spring memory alloy is sheathed at the outer surface of a fixing ring column in the steam chamber and forms a vertical state with a stream flowing direction in the steam chamber; the heating area of the shape memory alloy is enlarged and heating of the shape memory alloy is uniform. The utility model is suitable for any water heater; the shape memory alloy has big heating area of and uniform heating; the utility model has the advantages of rapid reaction, high sensitivity, reliable temperature control, reasonable structure, etc.
Description
The utility model is the temperature detect switch (TDS) that a kind of electric water boiler is used.
China Patent No. is 91208257.7 " steam temp sensing type temperature detect switch (TDS) ", it is to adopt the sheet memorial alloy, and by bolt with an end of sheet memorial alloy be fixed on vapor bin above, its shortcoming is: 1, because flow direction and the sheet memorial alloy balance of steam, make the sheet memorial alloy be heated inequality and cause delay of response, action hysteresis; 2, sheet memorial alloy uniformity is poor, stroke is bigger, and reliability is low; 3, bolt gets loose easily and the sheet memorial alloy is come off or is shifted and causes temperature detect switch (TDS) malfunctioning.
The purpose of this utility model is exactly to provide a kind of reaction quick, reliable electric water boiler temperature detect switch (TDS) in order to overcome above-mentioned weak point.
The utility model is to be made of vapor bin 3, marmem 1, rubber seal bullet circle 2 and contact switch 5.Marmem 1 of the present utility model is a kind of helical spring memorial alloy, and is nested in the outside of the clamping rings post 4 of vapor bin 3 the insides.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a marmem profile schematic diagram of the present utility model.
Referring to Fig. 1, Fig. 2, marmem 1 of the present utility model when cold conditions for shrinking, being when hot to two ends prolonged expansion state, and become plumbness with flow of vapor direction in the vapor bin 3, the heating surface area of marmem 1 is increased and be heated evenly.
When using the utility model, with flexible pipe vapor bin 3 is introduced and discharged to the steam of electric water boiler, pressing contact switch 5 makes it be in conducting state, electric water boiler is started working, cold water is heated, when water boiling (water temperature reaches 100 ℃), promptly having steam to enter vapor bin 3 is heated helical spring memorial alloy 1 and to the two ends prolonged expansion, at this moment, helical spring memorial alloy 1 forces rubber seal bullet circle 2 to move up by packing ring 6 to make contact switch 5 be in off state, thereby electric water boiler is quit work and reaches temperature controlled purpose.When electric water boiler need be reworked, just can heat and can enter the temperature state of a control automatically water as long as press contact switch 5.
Characteristics of the present utility model are: be suitable for any electric water boiler and use, memory The heating surface area of alloy is big and be heated evenly, and reacts quick, highly sensitive, and temperature control can Lean on, rational in infrastructure etc.
