Above housing 20, panel is installed, referring to Fig. 6, the top of panel 55 be provided with show control area 56, controller be positioned at show control area 56 under.Show that control area 56 is provided with a LED display 60, be used to show the water temperature of current setting.And, showing that also being provided with a plurality of temperature on the control area 56 sets button 57, temperature is set button 57 and is electrically connected with controller, and sends signal to controller.The user sets button 57 through temperature and sets safe water temperature, avoids water temperature too high and cause personnel to scald.In addition, show on the control area 56 also to be provided with temperature regulation button 61, be used for the temperature of setting is regulated.Nearby be provided with power button 62 at temperature regulation button 61.
In addition, near temperature is set button 57, also be provided with safe mode button 58, be used for sending signal to controller.When constant-temperature water faucet was worked, the controller acquiescence got into safe mode, promptly sets a water temperature upper limit threshold by the user, and when the user regulated water temperature above this water temperature upper limit threshold, safe mode started, and forbids that water temperature surpasses this water temperature upper limit threshold.At this moment, if the user need use the higher hot water of water temperature, need the long safe mode button of pressing to remove safe mode, the user promptly can heighten water temperature.
On panel 55, the below of safe mode button 58 is provided with two LED lights that are electrically connected with controller 59, is used to indicate current user mode.
The middle part of panel 55 also is provided with through hole 63,64, mixing valve 26 be positioned at through hole 63 under, and motor 75 be installed in through hole 64 under.
Referring to Fig. 7, be set with driving gear 77 in the rotating shaft 76 of motor 75, be set with driven gear 74 on the mandrel 73 of mixing valve 26, driving gear 77 and driven gear 74 engagements.During motor 75 work, rotating shaft 76 rotations also drive driving gear 77 rotations, are driven the rotation of driven gear 74 again by driving gear 77, and then drive mixing valve 26 rotations.Mandrel 73 outer ends at mixing valve 26 are provided with spline 72.
Present embodiment also has a manual adjustment rod 70, and it has knob 71, and the middle part can be passed the through hole 63 on the panel 55 and cooperate with the spline 72 of mixing valve 26, drives mixing valves 26 rotations through rotary knob 71.Therefore, when motor 75 breaks down, can come rotary mixing valve 26, thereby realize the manual tune of water temperature through manual adjustment rod 70.
Second embodiment:
Referring to Fig. 8, present embodiment has housing 80, is provided with cooling water inlet 81 and hot water inlet 83 at the two ends of housing 80, and in housing 80, is provided with mixing valve 85, and mixing valve 85 is provided with cold water hole 86, hot water hole 87 and water outlet 88.Cooling water inlet 81 is communicated with cold water hole 86 through cold water channel 82, and hot water inlet 83 is communicated with hot water hole 87 through hot water channel 84, and osculum 88 is communicated with exhalant canal 89, and exhalant canal 89 is communicated with water outlet 91, and mixed warm water flows out from water outlet 91.
Visible from Fig. 8, cooling water inlet 81, mixing valve 85 and hot water inlet 83 are arranged in straight line, can make things convenient for the installation of constant-temperature water faucet like this, also help the layout of constant-temperature water faucet interior conduit.
Be arranged on the right-hand member of housing 80 as the angle valve 92 of Flow valve, just be positioned at the outside of hot water inlet 83, make things convenient for user's use like this, meet general user's use habit.Certainly, Flow valve also can be arranged on the high order end of housing 80, just is positioned at the outside of cooling water inlet 81, and this moment, exhalant canal 89 should be designed to from extending to the left end of housing 80.Angle valve 92 is used for the water flow in the exhalant canal 89 of flowing through is controlled.
Temperature transducer 90 is installed in exhalant canal 89; Be used for the temperature of the current in the exhalant canal 89 of flowing through is detected; And the signal that detects transferred to controller (Fig. 8 does not show), the temperature that temperature that controller is set according to the user and temperature transducer 90 detect is controlled mixing valve 85.Certainly, present embodiment also is provided with motor (Fig. 8 does not show), and controller is through driving the rotating shaft rotation of motor to motor output signal, and rotating shaft drives the mandrel rotation of mixing valve through driving mechanism.
Certainly; Present embodiment also is provided with one-way valve on cooling water inlet 81, hot water inlet 83; And above housing 80, be provided with panel, panel is provided with temperature and sets button, safe mode button etc., and can carry out manual tune through using manual tune pole pair mixing valve; These are identical with first embodiment, repeat no more.
In addition, present embodiment can also have different embodiment, for example uses flexible pipe to connect cooling water inlet and hot water inlet; Flow valve separates with housing; The part of exhalant canal extends to outside the housing through flexible pipe, and Flow valve is positioned at outside, and control flows is through the water flow of exhalant canal.Again for example, panel is not installed in the top of housing, but the setting that is separated with housing, the circuit on the panel can be through the motor transmission signal of electric connection line to housing.Perhaps, constant-temperature water faucet is provided with remote controller, sends signal through remote controller to single-chip microcomputer, also can realize the purpose of the utility model.
The 3rd embodiment:
Referring to Fig. 9; Present embodiment has housing 100; Be respectively equipped with cooling water inlet 101 and hot water inlet 103 at the two ends of housing 100, be provided with mixing valve 105 at the middle part of housing 100, cooling water inlet 101, mixing valve 105 and hot water inlet 103 are arranged in straight line.
A temperature transducer 110 is installed in exhalant canal 109; Be used to detect the current temperature of exhalant canal 109 of flowing through; And the signal that detects is sent to controller (Figure 10 does not show); Controller drives mixing valve 105 rotations through drive motor (Figure 10 does not show), and then realizes the adjusting to water temperature.
Certainly; Present embodiment also is provided with one-way valve on cooling water inlet 101, hot water inlet 103; And above housing 100, be provided with panel, panel is provided with the temperature that is electrically connected with controller and sets button, safe mode button etc., and can carry out manual tune through using manual tune pole pair mixing valve; These are identical with first embodiment, repeat no more.
