The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Referring to Fig. 1-Figure 24, the blowdown apparatus of this toilet, comprise the water tank 9 being arranged on toilet 4, be arranged on the blow-off pipe in toilet 4, paper-breaking device 8 is serially connected in blow-off pipe, drainage switch 1 and tank lid 2 are arranged on water tank 9, drainage switch 1 joins with the draining valve 3 being arranged in water tank 9, on drainage switch 1, be provided with flood button 1.1 and little water button 1.2, blow-off pipe is two pass blow-off pipe 6, this two pass blow-off pipe comprises second blow-off pipe 6.2 that need to carry out the first blow-off pipe 6.1 of break process and not need to carry out break process, the head end of the head end of the first blow-off pipe 6.1 and the second blow-off pipe 6.2 is merged into same opening, in this opening, be provided with the switching mechanism 5 of whether opening for switching the head end of the first blow-off pipe 6.1 or the head end of the second blow-off pipe 6.2, the tail end of the tail end of the first blow-off pipe 6.1 and the second blow-off pipe 6.2 is merged into same outlet, wherein, the internal diameter of the first blow-off pipe 6.1 is larger than the internal diameter of the second blow-off pipe 6.2, and paper-breaking device 8 is serially connected in the first blow-off pipe 6.1.
In the present embodiment, described switching mechanism 5 comprises the switch boards 10 that is arranged in opening and for driving the motor 5.1 of switch boards 10 rotatings, this motor 5.1 joins with master controller 7.
The output shaft of motor 5.1 joins by gear pair and driving shaft 5.2, and driving shaft 5.2 joins with the rotating shaft 10.1 of switch boards 10.After a plurality of gears of gear pair in Figure 14 are intermeshing, form.Under the instruction that switching mechanism 5 sends at master controller 7, by controlling motor, drive switch boards 10 rotatings, realize the head end of the first blow-off pipe 8.1 or whether the head end of the second blow-off pipe 8.2 is opened.
For switching mechanism, can application reference number be 2013102012884 Chinese patent literature, just repeat no more herein.When master controller send enabling signal to switching mechanism after, electromagnetic clutch in switching mechanism is closed, motor starts to rotate, the moment of torsion of motor is by after step-by-step variable gear, drive output shaft rotation, output shaft drives switch boards to rotate, and realizes blowdown channel is switched.
On drainage switch 1, be provided with corresponding with flood button 1.1 and little water button 1.2 respectively the first travel switch and the second travel switch, this first travel switch and the second travel switch be or wired connection wireless with master controller 7 respectively.In other words, flood button, little water button have respectively the first relative travel switch and the second travel switch; Between control circuit on drainage switch 1 and master controller 7, contact employing wireless mode; When pressing flood button, when it touches the first corresponding travel switch, the control circuit on drainage switch 1 is to the signal of master controller 7 row's of transmission flood; When pressing little water button, when it touches the second corresponding travel switch, the control circuit on drainage switch 1 is to the signal of the master controller 7 little water of the row of transmission.
On drainage switch 1, be also provided with the changeover switch 1.3 whether starting for controlling paper-breaking device 8, this changeover switch 1.3 is wireless or wired connection with master controller 7.Changeover switch 1.3 can send wireless signal to master controller 7 by the control circuit being arranged on drainage switch 1.
During operation, press changeover switch 1.3, changeover switch 1.3 touches the travel switch corresponding with it, and the control circuit on drainage switch 1 sends the signal that paper-breaking device 8 can start to master controller.
Changeover switch 1.3 is arranged on flood button 1.1.This changeover switch 1.3 can be set to together with flood button 1.1 servo-actuated.Certainly, changeover switch 1.3 is arranged on separately to drainage switch 1 and is also fine, now, changeover switch 1.3 is all irrelevant with flood button 1.1 and little water button 1.2.
Drainage switch 1 is arranged in tank lid 2.
In the present embodiment, the first blow-off pipe 6.1 is siphon-type blow-off pipe.The second blow-off pipe 6.2 is siphon-type blow-off pipe.
Master controller 7 is arranged in toilet 4; Or master controller 7 is arranged on toilet 4 outsides.
During use, when changeover switch 1.3 is not pressed, that is to say and be not activated paper-breaking device 8, user presses flood button 1.1 or little water button 1.2, the first blow-off pipe 6.1 or the second blow-off pipe 6.2 are opened, the corresponding water yield, is rinsed toilet discharged to toilet from water tank, and booty is sent into sewer pipe along the first blow-off pipe 6.1 or the second blow-off pipe 6.2.
When changeover switch 1.3 is pressed, that is to say and start paper-breaking device 8, user presses flood button 1.1, enters the dirty pipe 6.1 of first row the water flush toilet of discharging in water tank, and dirt enters sewer pipe with swiftly flowing water after by paper-breaking device 8 fragmentations in the first blow-off pipe 6.1.
Switching mechanism can guarantee switch boards position in bowel movement when normality, in other words, when there is no electricity, normally bowel movement.
Its principle is: 1) when electromagnetic clutch disconnects, the spring on output shaft is always unfolds state, can guarantee that switch boards is in predetermined location; 2) when needs commutate, electromagnetic clutch is closed, electric motor starting, the torsion of motor is by electromagnetic clutch, gear pair and output shaft, Compress Spring, the commutation of drive switch boards, after having commutated, motor stops, and electromagnetic clutch unclamps, compressed spring self needs release pressure, and spring makes switch boards revert to desired location under the elastic force effect of himself.
