Embodiment
Below in conjunction with accompanying drawing embodiment invention is described in further detail.
Fig. 1 to Fig. 3 shows a mode of execution of numerical control temperature adjustment automatic faucet of the present invention; It comprises the faucet body 1 of a band cold water inlet 11 and water inlet of hot water 12.
Cold water inlet 11 connects the cold water ceramic valve core 55 of cold water numerical control electric valve 53 (or stepper motor) control of a band cold water drive motor 51; Water inlet of hot water 12 connects the hot water ceramic valve core 56 of hot water numerical control electric valve 54 (or stepper motor) control of a band hot water drive motor 52; As shown in Figure 1.
The middle part of faucet body 1 is provided with one and mixes water cavity 9, mixes water cavity 9 and is connected with cold water inlet 11, water inlet of hot water 12; As shown in Figure 2.The bottom of faucet body 1 connects the constant-temperature effluent frame 2 of a band constant temperature upper water-out mouth 21 and constant temperature lower outlet 22.Constant temperature upper water-out mouth 21 is the top water outlets that are used for sanitary bath equipment, for example from the top spraying head water outlet of bathtub; Constant temperature lower outlet 22 is the bottom water outlets that are used for sanitary bath equipment, for example nearby directly discharging water from bathtub.
Mixing water cavity 9 is connected with constant temperature upper water-out mouth 21, constant temperature lower outlet 22; As shown in Figure 2.Mix being provided with upper water-out switching solenoid valve 41 between water cavity 9 and the constant temperature upper water-out mouth 21, mix being provided with down water outlet switching solenoid valve 42 between water cavity 9 and the constant temperature lower outlet 22; As shown in Figure 3.
Mix in the water cavity 9 that a temperature transducer 7 being set, temperature transducer must place the water outlet of the good mixing water cavity 9 of temperature regulation.Temperature transducer 7 connects the single-chip microcomputer 3 as drive controller of a band power supply 10; Temperature indicating device 13 is set to liquid crystal digital display; What liquid crystal digital display was shown is that temperature is the water temperature in the mixing water cavity that regulates.Shown in Fig. 1,3.
The working principle of numerical control temperature adjustment automatic faucet of the present invention is to utilize single-chip microcomputer 3 to control numerical control electric valve 53,54, realizes constant temperature by numerical control electric valve 53,54 control hot water or cold waters' inflow.Power supply 10 is to use 6V, 4.5V or 3V DC power supply.
About the ceramic valve core 55,56 of two band numerical control electric valves 53,54 (China Patent No. that the inventor has authorized is ZL200420090744.9) of drive motor 51,52 or step motor control be contained in cold water inlet 11 and water inlet of hot water 12 places respectively.The user imports setting temperature, and single-chip microcomputer 3 is started working, and sends signal and gives numerical control electric valve 53,54 and control ceramic valve core 55,56, under the control of computer program, opens the hot water or cold water, and rotation is got up.Then, true temperature that computer is sensed according to temperature transducer 7 and the difference between the setting temperature, give the drive system signal constantly, make by the ceramic valve core 55,56 of numerical control electric valve (or stepper motor) control and ceaselessly regulating, stop operating in user's range of set temperature the time until coolant-temperature gage is constant.In washing process, computer control centre can constantly regulate ceramic valve core 55,56 automatically according to the variation of hydraulic pressure, and the inflow of control hot and cold water makes it constant in the temperature range that the user is provided with.
In addition, the present invention also is provided with the large, medium and small three last water outs and following water out that keep off the water yield and control respectively by upper water-out switching solenoid valve 41 and following water outlet switching solenoid valve 42.Very easy to use.
When numerical control temperature adjustment automatic faucet of the present invention uses, at first press power supply 10 switches on the panel or press the power switch of remote controller 14, at this moment the numerical control temperature adjusting water tap enters working state, goes up water out or lower outlet water outlet; The user is again from keeping away the control device or from the operation keyboard input temperature being set; Setting completed, and single board computer 3 promptly enters the temperature adjustment program state.In 5~10 seconds, constant-temperature water faucet flows out coolant-temperature gage and just can remain within user's range of set temperature, and in washing process, the temperature adjusting water tap coolant-temperature gage can remain in the temperature constant scope of user's setting later on; Its error is about ± 1 ℃.Simultaneously, can select large, medium and small three dash stream according to user preferences.Except above those functions, control panel also is provided with upper water-out and following water outlet computer control knob.With finishing, close by the power cutoff button or by the power supply of remote controller button and to get final product.
Numerical control temperature adjustment automatic faucet of the present invention can be avoided with the manually operation of rotation hot water combustion taps adjusting water temperature when family or hotel use; On liquid crystal digital display, demonstrate simultaneously the water-exit temperature that regulates; So it is very efficient and convenient to regulate the water temperature process.
