Description
Technical field
The invention belongs to household electrical appliance technical field, be related specifically to a kind of temperature control mechanism.
Background technology
The electric heating kettle of electric heating tube in drier dish can auto-breaking after water is boiled, has the advantage that firing rate is fast, easy to operate, safe, obtains the welcome of consumer, popularize gradually.But this kind of electric heating kettle generally only has single water boiling function, and not there is heat insulation function, if do not poured into rapidly in thermo jug after water is boiled, water so in electric heating kettle will cool, when winter, the cooling velocity of hot water is very fast, people often need again to press switch and again heat well-done water, and the degree of convenience of use is made a discount.In addition, also have some electric heating kettles to have heat insulation function, but it can only make water remain on the temperature of more than 95 DEG C, because temperature is too high, can not directly drink, and water be remained on the condition of high temperature and also can waste a large amount of electric energy.
Therefore be necessary that namely design one can realize function such as conventional heating such as grade to boil water, the temperature control mechanism at predetermined temperature range inside holding can be realized again.
Summary of the invention
The object of the invention is to propose a kind of temperature control mechanism, the holding temperature of this electric heating kettle can be set in certain temperature range, to improve degree easy to use, meets the requirement of consumer.
Temperature control mechanism of the present invention comprises the first terminal, the second terminal, kick temperature detect switch (TDS) and steam temperature detect switch (TDS), and described kick temperature detect switch (TDS) is being communicated with lower than during operating temperature, and disconnecting higher than during reset temperature, described reset temperature is higher than operating temperature; Described steam temperature detect switch (TDS) comprises main body and tappet, and described tappet is movably installed on the housing of main body, and described main body is provided with input terminal and lead-out terminal, and described main body is higher than during predetermined temperature upspringing tappet to make the separated of input terminal and lead-out terminal; The housing of described main body is also provided with insulation terminal, described insulation terminal and input terminal are all fixed on the side of tappet, described tappet is fixed with annular conductive film, and after described tappet is upspring by main body, above-mentioned annular conductive film can be communicated with insulation terminal and input terminal; One end of described kick temperature detect switch (TDS) is connected with the first terminal, and the other end is connected with the insulation terminal of steam temperature detect switch (TDS); The lead-out terminal of described steam temperature detect switch (TDS) is connected with the first terminal, and the input terminal of steam temperature detect switch (TDS) is connected with the second terminal.
The operation principle of above-mentioned temperature control mechanism is as follows:
In use, this temperature control mechanism is serially connected with between power supply and heater block, heater block generally has two power lines, as long as be serially connected with by this temperature control mechanism in a power line wherein, and the power end that another power line of heater block can be directly corresponding to civil power is connected.
Time to boil water, press tappet, the input terminal of steam temperature detect switch (TDS) is communicated with lead-out terminal, thus be communicated with power supply and heater block, electric current flows through electric heating plate, is the water heating in kettle.When poach is opened and is reached predetermined temperature, the main body action of steam temperature detect switch (TDS) and tappet of upspringing, make the separated of input terminal and lead-out terminal, be communicated with insulation terminal and input terminal simultaneously, complete water boiling function, now because water temperature is higher than reset temperature, kick temperature detect switch (TDS) is off state, therefore state is off between power supply and heater block, electric heating plate power-off.
After losing thermal source, water temperature can constantly reduce, and when water temperature is lower than operating temperature, kick temperature detect switch (TDS) transfers connected state to, and now electric heating plate is communicated with power supply by kick temperature detect switch (TDS), electric heating plate energising work, is the water heating in kettle; Water temperature raises gradually, and after water temperature is higher than reset temperature, kick temperature detect switch (TDS) transfers off-state to again, and electric heating plate power-off quits work, and goes round and begins again like this, achieves heat insulation function, and the water temperature in kettle can remain between reset temperature, operating temperature.By selecting the kick temperature detect switch (TDS) with suitable return temperature, operating temperature, the water temperature in kettle can be made to remain in required temperature range.
Compared to now the most frequently used insulating pot temperature detect switch (TDS), the tappet of above-mentioned steam temperature detect switch (TDS) is provided with annular conductive film, housing is provided with insulation terminal, and the insulating pot temperature detect switch (TDS) of structure and working principle all with now the most frequently used of above-mentioned steam temperature detect switch (TDS) main body is identical.Now the most frequently used insulating pot temperature detect switch (TDS) is generally positioned at steam channel, the water vapour produced when utilizing water to seethe with excitement makes the bi-metal plate deformed in insulating pot temperature detect switch (TDS), and utilize distortion promote tappet by lever principle and be arranged at the power switch at kettle body handle place, thus making electric kettle at the boiled rear auto-breaking of water, its power-off can not Self-resetting.There are a lot of disclosed document (as China Patent No. 00103897.4 and 200810120109.3 patent of invention) and application example about above-mentioned now the most frequently used insulating pot temperature detect switch (TDS), repeated no more herein.
Above-mentioned kick temperature detect switch (TDS) is the temperature controller of a kind of bimetal leaf as the temperature module, when electrical equipment normally works, bimetal leaf is in free state, contact is in closed/off-state, when temperature reaches operating temperature, bimetal leaf is heated and produces internal stress and rapidly action, opened/closed contact, cut off/connect circuit, thus play temperature control function.Kick switches has been widely used in, in various electrical equipment, repeating no more herein.
Further, for avoiding controlling confusion, described predetermined temperature is higher than reset temperature.
Temperature control mechanism structure of the present invention is simple, cost is low, control is reliable, after poach is opened, water temperature can be remained in suitable temperature range, such as, say in applicable temperature range of directly drinking, convenient for users, be highly suitable in the electrical equipment such as electric kettle.
