Further, on described the first tooth bar 83 and the second tooth bar, be respectively equipped with a travel switch, and two travel switches are electrically connected to central processing unit respectively, are used for accurately detecting and controlling the position of tooth bar.
In the present invention, the method for utilizing motor and gear to control the cross-sectional area of hot and cold water pipe 3 is controlled temperature, and theoretical foundation is as follows:
According to law of conservation of energy: the hot water or cold water is energy identical (ignoring dissipate energy) before and after mixing
Before E+E after=E mixes
E=T * C * M (E is energy, and T is temperature, and C is specific heat capacity, and M is quality) again
And M=L * S * ρ (L is length, and S is cross-sectional area, and ρ is density)
That is: T 1* C * (μ * t * S 1* ρ)+T 2* C * (μ * t * S 2* ρ)=T * C * (μ * t * S * ρ)
(T1, S1 are hot water temperature, water-supply-pipe cross-sectional area; T2, S2 are cold water temperature, water-supply-pipe cross-sectional area; T is the time, and μ is flow velocity, and S mixes the cross-sectional area of rear water column for the hot water or cold water, and T is the transversal temperature of water-supply-pipe after cold, boiling water mixes, S=S1+S2)
Abbreviation obtains:
T=(T 1×S 1+T 2×S 2)÷(S 1+S 2);
Because of T1, T2 is known, thereby can regulate S1, and S2 (hot water or cold water's water-supply-pipe cross-sectional area) regulates the size of T.
So: as long as control S1, S2, just can control the temperature T of exporting water.
In addition, according to the linear relationship of the water outlet water yield and time, can also increase timer in housing, be used for controlling the output water yield, its theoretical foundation is:
V=S×h=S×(μ×t)=(S×μ)×t
(S is cold, the rear water column cross-sectional area of boiling water mixing, and μ is flow velocity, is constant, and t is the time, and V is directly proportional to t.
During use, input temperature and the water yield of setting by keyboard, obtain hot water or cold water's temperature by sensor, central processing unit is by formula T=(T 1* S 1+ T 2* S 2) ÷ (S 1+ S 2); , calculate S1 and the S2 of a reasonable set, then, central processing unit calculates the number of turns that the first motor and the second motor need to rotate, and drive circuit drives the first motor and the second motor rotation, arrives assigned address, meanwhile, central processing unit calculates and obtains the required time of the water yield of setting, then, the first magnetic valve and the second magnetic valve are opened, timer starts simultaneously, carries out countdown, after countdown by the time finishes, the first magnetic valve and the second closed electromagnetic valve, complete the process of whole water receiving.
In whole water receiving operating process, the ROM memory is preserved total data whole or that weigh, and guarantees that data can not lost when power down suddenly.
When motor rotation, because motor is fixed, tooth bar is movable, and tooth bar can move around on horizontal plane, reach the purpose of controlling sectional area, and, after completing a water receiving operation, all data zero clearings, the motor drive direction running, make tooth bar return to initial position.
Should be understood that; the above-mentioned description for preferred embodiment is comparatively detailed; can not therefore think the restriction to scope of patent protection of the present invention; those of ordinary skill in the art is under enlightenment of the present invention; do not breaking away from the scope situation that the claims in the present invention protect; can also make the various deformation such as replacement, simple combination, within these all fall into protection scope of the present invention, the scope of asking for protection of the present invention should be as the criterion with claims.
