Abstract
The utility model relates to a temperature control switch for an electrothermal boiling water device and solves the problem that the similar product has presently insensitive action and high cost. The utility model is characterized mainly in that the bottom part of the top cover of a container is provided with a steam hole communicated with a chamber whose interior is provided with a dual metal alloy sheet; the dual metal alloy sheet forms a concave shape under the normal temperature, and the dual metal alloy sheet forms a convex shape when the water is boiling. In addition, a driving support rod for driving contacts to change is arranged on the dual metal alloy sheet. The device has the advantages of electricity saving, heat insulation, etc.; a power supply can be switched off in the device within 30 seconds, after the water becomes boiling; simultaneously, the device has the function of auditory and visual warning. The utility model is suitable for various electrothermal boiling water devices.
Description
The utility model relates to temperature detect switch (TDS), especially a kind of electric water boiler temperature detect switch (TDS).
Present domestic have temperature detect switch (TDS) and two kinds of forms of safety type switch.
1, safety type switch: the safety type switch is to consider from protection heater itself; it has water to dryout the characteristics of back outage; its weak point: because pedestal adopts the bakelite material and connects with heater; work is the back seat body deformability for several times; move out of control; inoperative on the contrary, just outage after water is done in addition wastes energy.
2, temperature detect switch (TDS): China adopts temperature detect switch (TDS) all to have the boiling water outage basically at present, and volume is little, saves characteristics such as the energy, but its weak point:
＜1〉adopt the memorial alloy material to make the temperature control original paper at present, temperature control is inaccurate, because of the also below standard standard of China's memorial alloy.＜2〉adopt the heat conduction temp sensing type, be vulnerable to water heater wall thickness difference, factors such as element material, physical dimension, temperature controlled compartment sealing are all influential to temperature control.＜3〉adopt steam inlet pipe control temperature to exist throttle flow size, steam pipe height, installation site all to be subjected to influencing in various degree.＜4 〉, install and seal also relatively complicated because temperature detect switch (TDS) and heater are installed bottom side.＜5〉adjust the relative position of memorial alloy sheet and electric switch with micro-adjusting mechanism, structure is complicated.
The purpose of this utility model: at the problems referred to above, design a kind of simple in structure, be active in one's movements, the electric water boiler temperature detect switch (TDS) of safety durable.
The utility model purpose is to realize like this, be provided with a steam hole in the bottom of container cap, with in the cavity that this hole is communicated with a bimetallic alloy sheet that is spill is at normal temperatures arranged, and a perpendicular supported moving bar is arranged at this sheet top that is convex when boiling water.When water is boiled, steam by steam hole, utilize air pressure that spill bimetallic alloy sheet is deformed into convex, at this moment, supported moving bar on it drives corresponding contacts, cuts off the electricity supply, acousto-optic is notified simultaneously.
That this device has is simple in structure, temperature control is accurate, advantage such as safe in utilization.
Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail.
Accompanying drawing is the utility model outward appearance cut-away view.
In the accompanying drawings, 1 heating resistor, 2 container caps, 3 bimetallic alloy sheets, 4 rubber sealing films, 5 supported moving bars, 6 sheet metals, 7 buzzers, 8 indicator lights, integrated of 9 sound equipments, 10 make contact, 11 moving contacts, 12 break contacts, 13 cavitys, 14 steam holes, 15 housings, 16 supply hubs.Among this figure, in cavity 13, there is one can prevent that steam from entering rubber sealing film 4 in its cavity from steam hole 14; In addition, fix a sheet metal 6 that has moving contact 11 in the upper end of supported moving bar 5, as cutting off the electricity supply, and carry out the actuating arm that acousto-optic is notified.
In conjunction with its course of work of above-mentioned description of drawings:
This switch is positioned at the upper end of electric heater body, and bimetallic alloy sheet 3 is spill at normal temperatures, contact 11,12 closures, and as if power connection this moment, the heating resistor 1 that is in the water is started working.After water is boiled in 30 seconds, bimetallic alloy sheet 3 becomes convex by spill suddenly, moves on the supported moving bar 5 on it, and the moving contact 11 on the sheet metal 6 is disconnected with break contact 12---the loops of cutting off the electricity supply; Simultaneously moving contact 11 again with make contact 10 closures, connect the acousto-optic circuit of notifying: indicator light 8 is bright, and buzzer 7 sends melodious sound.Notify the user.
Claims (3)
1, a kind of heating resistor, break contact of comprising, the electric water boiler temperature detect switch (TDS) of housing, its feature: be provided with a steam hole 14 in the bottom of container cap 2, with have one at normal temperatures to recessed bimetallic alloy sheet 3 in the cavity 13 that this hole is communicated with, and a perpendicular supported moving bar 5 is arranged at the top of convex bimetallic alloy sheet 3 when boiling water.
2, electric water boiler temperature detect switch (TDS) according to claim 1, its feature a: rubber sealing film 4 that can prevent that steam from entering from steam hole 14 is arranged in cavity 13.
3, electric water boiler temperature detect switch (TDS) according to claim 1, its feature: fix a sheet metal 6 that has moving contact 11 in the upper end of supported moving bar 5.
