Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is explained in detail.
As Fig. 1 and shown in Figure 3, the utility model is provided with power supply unit 10, lamp switch 20, lighting burner 30, relay 40, ventilating fan 50, control unit 60 and power supply changeover device 70 in the bathroom, wherein:
This power supply unit 10 is used to provide the utility model required power supply when using.
This lamp switch 20 is connected with power supply unit 10 with lighting burner 30, and lamp switch 20 is in order to the work of control lighting burner 30.
This ventilating fan 50 is connected with relay 40, and relay 40, ventilating fan 50 are and lamp switch 20, lighting burner 30 form shape in parallel, and relay 40 forms with lamp switch 20 down in non-action status and electrically connects, and relay 40 in operating state down with power supply unit 10 formation electric connections.
This control unit 60 is connected in relay 40, and control unit 60 is used for the action of control relay 40.
This power supply changeover device 70 is used for power supply is converted to can be for the power supply of control unit 60 uses.
Extremely shown in Figure 6 as Fig. 1, find out by knowing among Fig. 1 and Fig. 2, when lamp switch 20 is not switched to the state of conducting lighting burner 30 by the user, relay 40 is not operating state, therefore ventilating fan 50 also can't be by the required power supply of relay 40 acquisition work, make lighting burner 30 and ventilating fan 50 all be the state of not working, and when the user is switched lamp switch 20 and is made the power turn-on lighting burner 30 of power supply unit 10, as shown in Figures 3 and 4, relay 40 is also obtained the power supply of power supply unit 10 simultaneously by lamp switch 20 places, and then ventilating fan 50 is worked, and being supplied to control unit 60 after this power supply is changed via power supply changeover device 70 uses, make control unit 60 work, and whether circuit for detecting that control unit 60 is connected 61 can continue detecting the power supply lighting burner 30 of flowing through, see also Fig. 5 and shown in Figure 6, when detecting power supply, circuit for detecting 61 flows through behind the lighting burner 30, control unit 60 can be behind certain hour, drive the drive circuit 41 of relay 40, make relay 40 actions and the electric connection of cut-out and lamp switch 20, and form electric connection with power supply unit 10, continue the required power supply of supply ventilating fan 50 and control unit 60, and cut off lamp switch 20 when lighting burner 30 is quit work as the user, because this moment, relay 40 actions kept being electric connection with power supply unit 10, therefore ventilating fan 50 still can continuous firing after lighting burner 30 quits work, yet when lighting burner 30 quits work, circuit for detecting 61 can detect the non-transformer lighting burner 30 of flowing through simultaneously, this moment, control unit 60 meetings stop to drive drive circuit 41 behind certain hour, make relay 40 actions and the electric connection of cut-out and power supply unit 10, as shown in Figures 1 and 2, ventilating fan 50 is quit work.Loop with power supply changeover device 70 is connected to lamp switch 20 simultaneously, and because of lamp switch 20 has disconnected, entire circuit is in not electric consumption of off-position, replys the original state of Fig. 1 Fig. 2.
As above, after user's conducting lamp switch 20 enters the bathroom, lighting burner 30 and ventilating fan 50 meeting continuous firings, when the user leaves the bathroom and cuts off lamp switch 20, lighting burner 30 can quit work, and 50 meeting continuous firing a period of times of ventilating fan are discharged a large amount of steam in the residual bathroom, quit work again, use to make things convenient for the user.
See also Figure 1 and Figure 2 again, control unit 60 of the present utility model can be a microcontroller, utilize circuit for detecting 61 to detect the voltage level of the lighting burner 30 of flowing through, make control unit 60 drive drive circuit 41 actions, allowing drive circuit 41 utilize power supply to make the coil motion of relay 40, and then the electric connection of switching power supply 10 and lamp switch 20, and after relay 40 stops to move, ventilating fan 50 is flowed through with the control unit 60 neither power supplys that have, with the electric energy that avoids waste.
Moreover, because the suitable weak point of switch motion time of relay 40, and the machinery inertial of ventilating fan 50, therefore in ventilating fan 50 runnings, make relay 40 actions, can the running of ventilating fan 50 not exerted an influence.
Therefore, the utility model is for can solve the deficiencies in the prior art, its key technology is, the utility model utilizes control unit 60 ventilating fan 50 of delaying time to quit work, allow the user cut off the work of lighting burner 30 after, ventilating fan 50 can continuous firing a period of times with the bathroom residual steam discharge, the user is convenient to be used to allow, and ventilating fan 50 is after quitting work, the power supply control unit 60 of also can not flowing through, therefore the loss that can not produce electric energy is to avoid waste of energy.
Should be appreciated that the foregoing description only to be used to the utility model is described and be not used in the restriction scope of the present utility model.In addition, should be appreciated that after having read content of the present utility model, those skilled in the art can make various changes or modifications invention, these equivalent form of values fall into protection domain of the present utility model equally.
