Description
Technical field
The invention belongs to a kind of method of water boiling of electric kettle, relate to the control of this process water boiling to boil water, especially finger is a kind of is suitable for the control of Different Altitude Regions water boiling and solves in institute's employing scheme having the problem of conflict, so that can cut off feed circuit exactly automatically when water seethes with excitement.
Background technology
At present, electric kettle uses in family or office space widely.Adopt this water boiling of electric kettle, when water seethed with excitement, control circuit also can cut off feed circuit automatically, stopped heating.Usually, people are that way by continuous C.T. and water boiling point realizes.But this needs producer that the temperature of each local water boiling is measured and set in circuit, makes its manufacturing have no small trouble.
Nonetheless, also cannot stop people and take it to another place from a place, bring bigger problem therefrom, for example, when the boiling point of new local water is higher, the phenomenon that heats then can appear just stopping when water does not seethe with excitement, and for example, and when the boiling point of new local water is low, then can occur water seethe with excitement always but fail to cut off feed circuit stop the heating, until dry combustion method occurring, this not only wastes electric energy, and dangerous.
In addition, the electricity kettle also exists the user to add the problem of water simultaneously in process to boil water, what temperature always constantly rose in process to boil water on the one hand, owing to add the problem that the lower cold water of temperature then can cause temperature to descend on the contrary, this can cause interference for control on the other hand.
Moreover, area in cold, when temperature≤0 ℃, also there is heat absorption on one side in the water of electric kettle the inside in process to boil water, Yi Bian maintain 0 ℃ or less than 0 ℃ situation, because during temperature≤0 ℃, water also is in icing state, and it is mobile poor, and this will be along with the process of heating, the temperature of electric heating body is constantly soaring, finally causes the problem of himself burning.
Summary of the invention
The object of the present invention is to provide a kind ofly can automatically be suitable for the different water boiling point of Different Altitude Regions, utilize the characteristics of heating process to boil water, the control method of the water boiling of electric kettle that power supply stops to heat is cut off in boiling automatically to water.
Its purpose is realized by following scheme:
A kind of control method of water boiling of electric kettle is characterized in:
(1), power to electric heating body, by control circuit control feed circuit by electric heating body to the evolution of heat of kettle body;
(2), survey the Current Temperatures of water in the kettle body by the temp probe of control circuit;
(3), if within a certain period of time, the Current Temperatures that temp probe records no longer descends, and has several times to remain unchanged, then control circuit cuts off feed circuit and stops to the electric heating body power supply and withdraw from.
Like this,,, and there is the several times temperature to keep identical, can thinks that then water seethes with excitement,, withdraw from control so just stop heating if the Current Temperatures of temp probe no longer descends in the different moment.The benefit of this method is only can get rid of just must recomputate the deficiency of number of times constantly indivedual because the appearance of certain special circumstances causes a temperature identical, and this can be adapted to complicated weather situation better.
Its purpose also can be realized by following scheme:
A kind of control method of water boiling of electric kettle is characterized in:
(1), power to electric heating body, by control circuit control feed circuit by electric heating body to the evolution of heat of kettle body;
(2), survey the Current Temperatures of water in the kettle body by the temp probe of control circuit;
(3), if within a certain period of time, it is constant continuously that several times appear in the Current Temperatures that temp probe records, then control circuit cuts off feed circuit and stops to the electric heating body power supply and withdraw from.
Like this,,, can think also that then water seethes with excitement,, withdraw from control so just stop heating if the Current Temperatures of temp probe has several times to keep identical continuously in the different moment.The advantage of this method is the different moment in the same time, and the temperature that temp probe records water is all identical, thinks therefore and seethe with excitement that this judgement will be more accurate.
The control method of thus obtained water boiling of electric kettle can be suitable for the different water boiling point of Different Altitude Regions, solved the trouble that producer need measure and be set in circuit when making electric kettle the temperature of each local water boiling.
Moreover, owing to no matter be in heating process, to add cold water etc., still in the rapid decline that meets with outside air temperature, at one time, the possibility of the heat that appearance water absorbs and the heat equivalent of its release is very little, thereby if the several times water temperature occurring does not change, can think that then water seethes with excitement.Therefore, the control method of water boiling of electric kettle of the present invention, the effect that also has the external interference of preventing can be got rid of temperature-resistant " false boiling " phenomenon of bringing of a certain moment that may occur, thereby improve the accuracy of boiling control in heating process.
The boiling point of considering sea level place water is 100 ℃, for adaptation is higher than most of places on sea level and for to preventing the consideration of dry combustion method, 100 ℃ can be limited as a ceiling temperature, and propose following two kinds of solutions again.
Wherein, a kind of scheme is:
A kind of control method of water boiling of electric kettle is characterized in:
(1), power to electric heating body, by control circuit control feed circuit by electric heating body to the evolution of heat of kettle body;
(2), survey the Current Temperatures of water in the kettle body by the temp probe of control circuit, the Current Temperatures of temp probe and 100 ℃ are compared, when Current Temperatures 〉=100 of temp probe ℃, then control circuit cuts off feed circuit and stops to the electric heating body power supply and withdraw from;
(3), when Current Temperatures＜100 of temp probe ℃, if in the regular hour, the Current Temperatures of temp probe no longer descends, and there are several times to remain unchanged, then control circuit cut-out feed circuit stop to the electric heating body power supply and withdraw from, otherwise, repeating step (2).
Another kind of scheme is:
A kind of control method of water boiling of electric kettle is characterized in:
(1), power to electric heating body, by control circuit control feed circuit by electric heating body to the evolution of heat of kettle body;
(2), survey the Current Temperatures of water in the kettle body by the temp probe of control circuit, the Current Temperatures of temp probe and 100 ℃ are compared, when Current Temperatures 〉=100 of temp probe ℃, then control circuit cuts off feed circuit and stops to the electric heating body power supply and withdraw from;
(3), when Current Temperatures＜100 of temp probe ℃, if in the regular hour, it is constant that continuous several times appear in the Current Temperatures of temp probe, then control circuit cuts off feed circuit and stops to the electric heating body power supply and withdraw from, otherwise, repeating step (2).
Like this,, then no matter think all that for any area water seethes with excitement,, withdraw from control so just stop heating when Current Temperatures 〉=100 of temp probe ℃; When Current Temperatures＜100 of temp probe ℃, then in the different moment, if the Current Temperatures of temp probe no longer descends, and have the several times temperature to keep identical, perhaps the several times temperature is identical continuously, can think that then water seethes with excitement, so just stop heating, withdraw from control.
It is desirable to, in the said method, step (1) changes into as follows:
(1), survey the Current Temperatures of water in the kettle body, the Current Temperatures of temp probe is compared with 0 ℃, when Current Temperatures≤0 of temp probe ℃, then control circuit control feed circuit do not heat and withdraw to electric heating body by the temp probe of control circuit; When Current Temperatures＞0 of temp probe ℃, power to electric heating body by control circuit control feed circuit, by the electric heating body evolution of heat.
Like this, also monitor in the situation below 0 ℃ or 0 ℃ for temperature, because under this situation, the temperature of water also exists to raise or remain unchanged and continues possibility of heat absorption, but still is in icing state and does not melt, and continues heating and will cause constantly riseing of electric heating body temperature, and then may there be the problem that electric heating body is burnt, therefore, this method has to be handled this situation, avoids the appearance of this situation.
The control method of water boiling of electric kettle of the present invention, compare with existing control method, area with the Different Altitude of being suitable for use in, be used for the control that boiling stops to heat to water, and the accuracy that boiling is judged to water has more high-precision advantage, can get rid of adding the various disturbed conditions that may occur in the heat control, and to temperature maintenance 〉=100 ℃ situation or≤0 ℃ situation handles especially, helps preventing the phenomenon of dry combustion method.
