Except described diode 71c, resistor 71d and photo-coupler 72a, the relay abnormity detection portion 14 of present embodiment also has the transistor 72c that is connected with the outlet side of photo-coupler 72a and resistor 72b and the 72d that is connected with this transistor 72c.In the present embodiment, the photo detector of photo-coupler 72a is made of photistor, and the emitter stage of this photistor is connected with the base stage of transistor 72c via resistor 72b.And, the grounded emitter of transistor 72c, colelctor electrode is connected with the terminal of resistor 72d.The voltage (current potential) at the 72e place, company contact (node) between terminal of this resistor 72d and the colelctor electrode of transistor 72c is imported into master control part 10.And the colelctor electrode of another terminal of resistor 72d and the photistor of photo-coupler 72a is connected to positive voltage source (Vcc) together.Positive voltage source (Vcc) is made of the lead-out terminal of power circuit part 11, perhaps is connected with this lead-out terminal.
According to this structure, photistor is not receiving the light time cut-off of self-emission device, transistor 72c cut-off, the voltage of node 72e is positive voltage (Vcc), on the other hand, photistor is receiving the light time conducting of self-emission device, transistor 72c conducting, and the voltage of node 72e is earthing potential.Thus, make binary signal after the binary signal counter-rotating of the photistor output of photo-coupler 72a from node 72e output, as the relay fault detection signal.
The relay drive division 12 of present embodiment has: resistor 73a, transistor 73b, resistor 73c, transistor 73d, transistor 73e, resistor 73f, diode 73g and diode 73h.Drive signal via resistor 73a, diode 73h, transistor 73e to the base stage input relay of transistor 73b from master control part 10.And, the grounded emitter of transistor 73b, colelctor electrode is connected with a terminal of the coil 22 of each relay mechanism 20.And the base stage of transistor 73b is drawn on the resistor 73f, and is connected with the colelctor electrode of transistor 73d.The grounded emitter of transistor 73d, the rectification square of base stage and diode 73g to the downstream be connected.The rectification square of diode 73g to upstream side be connected with detection of electrical leakage section 13 via resistor 73c.The rectification square of diode 73h to the downstream be connected with the base stage of transistor 73e, upstream side is connected with master control part 10 via resistor 73a.The grounded emitter of transistor 73e, colelctor electrode is connected with the base stage of resistor 73f, transistor 73b and the colelctor electrode of transistor 73d.Another terminal of the coil 22 of each relay mechanism 20 assigns the position of relay contact 21 more to be connected near the part of attaching plug 30 sides with the ratio of main supply power path 81.
When having exported from master control part 10 coil 22 is switched on and when making the signal (hereinafter referred to as the relay connection signal) of relay contact 21 closures, transistor 73e cut-off, transistor 73b conducting, so, relay contact 21 closures.Relative therewith, when having exported the relay cut-off signal that makes relay contact 21 disconnections from master control part 10, transistor 73e conducting, transistor 73b cut-off is so relay contact 21 disconnects.
And, when producing electric leakage, produce signal from the 13 input electric leakages of detection of electrical leakage section.When transistor 73d is not transfused to electric leakage generation signal, transistor 73d cut-off, so, transistor 73b conducting, relay contact 21 closures.Relative therewith, when having electric leakage generation signal to be input to transistor 73d, transistor 73d conducting, so, transistor 73b cut-off, relay contact 21 disconnects, and carries out electrical leakage breaking.
[economize on electricity action and control thereof in the electrical leakage breaking section]
Economize on electricity action and the control thereof of the electrical leakage breaking section of present embodiment then, are described according to Fig. 3～Fig. 5.Fig. 4 is the flow chart of an example that the control of the economize on electricity action of being undertaken by master control part is shown.Fig. 5 (a) and (b) be the relay on-off action decision signal that uses in the affirmation for the cut-out of the electrical leakage breaking section that carries out following control shown in Figure 4 action, to the normal situation about opening and closing of relay with open and close in produced the curve map that unusual situation compares.
In the present embodiment, if relay drive division 12 and relay abnormity detection portion 14 have adopted the foregoing circuit structure, when then testing (the affirmation test that is the electrical leakage breaking function) in the disconnection of carrying out relay contact 21 and closed affirmation, except can judge whether relay contact 21 normally disconnects and closure, can also in the disconnection of relay contact 21 or closure, produce in the unusual situation, judge that this is which kind of is unusual unusually.
Operated the battery-conserving switch 59 that is disposed on demonstration/operating portion 52 and be set as in the situation of energy-saving mode the user, be timed to through (in the situation that present embodiment is 8 hours) during till the stipulated time from establishing, master control part 10 is carried out the control of the energy-saving mode of the following stated.
At first, as step S101, master control part 10 determined whether from the affirmation of the use state of last time is finished through the stipulated time.In the situation that not yet pass through the stipulated time (step S101: no), repeatedly judge until through the stipulated time, make a series of control standby.
In the situation that reach the stipulated time or passed through in the situation of stipulated time (step S101: be), as step S102, judge whether seat device 50 is in the state that do not use.In the present embodiment, as depicted in figs. 1 and 2, seat device 50 has seat occupancy sensor 56 and human body sensor 57, so, in these sensors are during certain, do not detect the user take a seat or the situation of user's existence under, be judged to be the state that do not use that is in.Here, for energy-conservation and can will suppress to be set as for the holding state of required MIN power consumption in the situation of use state of seat device 50, also can be judged to be the state that do not use with entering into the situation that holding state rises during having passed through necessarily.In the present invention, at least use the result that detects taking a seat of situation about being seated in the toilet seat section 53 and detect in the judgement of using state, detect the result that user that the user is present in the situation in the place that arranges of seat device 50 detects and get final product, concrete decision method can be method arbitrarily.
In addition, also can with do not carry out seat device 50 toilet seat heater 42 heating when action and be judged to be the state that do not use when not carrying out the cleaning action of washer jet 45, but, in the present invention, if consider except the economize on electricity action and also will carry out electrical leakage breaking, then preferred any part with user's health does not all contact the condition judgement of seat device 50 for not using state.Therefore, in the present embodiment, more preferably, master control part 10 is used the testing result of at least either party in take a seat detection and the human detection in the judgement of the use state of seat device 50.Do not use state (being in the use state), master control part 10 to carry out standby until become not use state (step S102: no) in the situation that be judged to be not to be in.
In addition, in the situation that be judged to be in do not use state or become not use state after (step S102: be), as step S103, master control part 10 stops coil 22 energisings and relay cut-off signal that relay contact 21 is disconnected to relay drive division 12 output, as relay drive signal.
Here, in step S103, behind the output relay cut-off signal, the transistor 73b of relay drive division 12 cut-off.Start work if relay mechanism 20 is normally resolved, then the energising of coil 22 is cut off, and relay contact 21 disconnects thus.
Because coil 22 is energized before the output relay cut-off signal, so, pass into the alternating current of specified period from AC power to main supply power path 81, as mentioned above, photo-coupler 72a by relay abnormity detection portion 14 detects this alternating current, 10 inputs (by every half period reverse) binary signal corresponding with the cycle of this alternating current from node 72e to master control part is as relay on-off action decision signal.Consequently, in the situation that relay mechanism 20 normally carries out on-off action, shown in Fig. 5 (a), during the output relay connection signal (middle part among the figure), export accordingly binary signal (left side, figure middle and lower part) with the cycle of alternating current (figure middle and upper part), and this binary signal is output to master control part 10.Here, for easy, will switch on and make the relay drive signal of relay contact 21 closures be called the relay connection signal coil 22.
Therefore, when in step S103, having exported the relay cut-off signal, if relay mechanism 20 is normally to disconnect action, then relay contact 21 disconnects, so, alternating current is not passed into main supply power path 81, becomes the signal of the one party (being high level here) that is fixed as in height (H) level or low (L) level as the binary signal of relay on-off action decision signal.On the other hand, if relay contact 21 still is kept closed because thereby the closures such as welding cause when the output relay cut-off signal relay contact not disconnect, then shown in Fig. 5 (b), even switch to cut-off signal from the relay connection signal, also will continue the output binary signal corresponding with the cycle of alternating current.Below, this is called " the connection fault " of relay contact 21 unusually.
Therefore, master control part 10 obtains relay on-off action decision signal from relay abnormity detection portion 14 in step S104, in step S105, judge whether relay on-off action decision signal is corresponding with the cycle of AC power, corresponding if (step S105: be), then as mentioned above, be judged to be relay contact 21 and produced connection fault (step S106).On the other hand, if not corresponding (step S105: no), then relay contact 21 normally disconnects, so, entering step S107, master control part 10 switches to electricity-saving state with seat device 50 integral body, the beginning energy-saving mode.
Usually, lower in energy-saving mode, the energising that is warm water heater 41a, the drying heater 41b that will consume more electric power, toilet seat heater 42 etc. is cut off, and under energy-saving mode of the present invention, by relay contact 21 is disconnected, thus, not only described each heater 41a, 41b, 42 are cut off, the energising that also will drive the coil 22 of relay contact 21 is cut off.Therefore, can further improve energy-saving effect.
In following step S108, judge whether seat device 50 is in the use state.That is, master control part 10 determines whether and continues to keep the economize on electricity action.Namely, if seat device 50 is not in the use state, then master control part 10 is judged as not use state lasting, the guard relay cut-off signal, proceed economize on electricity action (step S108: no), if seat device 50 is in the use state or seat device 50 becomes use state (step S108: be) and be judged to be, then enter step S109, in order to switch to normal mode from energy-saving mode.
In step S109, master control part 10 switches to above-mentioned relay connection signal with the relay cut-off signal, and it is outputed to relay drive division 12.
Here, after in step S109, having exported the relay connection signal, in the situation that relay mechanism 20 normally carries out on-off action, relay contact 21 closures, so alternating current is passed into main supply power path 81, as mentioned above, export accordingly binary signal as relay on-off action decision signal with the cycle of alternating current, and this binary signal is output to master control part 10.On the other hand, in the on-off action of relay mechanism 20, produced in the unusual situation, even output relay connection signal, relay contact 21 can be not closed and will still remain open state yet, so, alternating current can not be passed into main supply power path 81, becomes the state that does not generate the binary signal corresponding with the cycle of AC power.Therefore, for example shown in Fig. 5 (a), binary signal becomes the signal (right side, figure middle and lower part) that is fixed as mentioned above high level.Below, this is called " open failure " of relay contact 21 unusually.
Therefore, master control part 10 obtains relay on-off action decision signal (step S110), judges this relay on-off action decision signal of obtaining whether corresponding with the cycle of alternating current (step S111).The cycle of relay on-off action decision signal and AC power that is judged to be when master control part 10 is to seasonable (step S111: be), enter step S112, because relay contact 21 disconnects according to the relay cut-off signal and according to the relay connection signal and closure, so, master control part 10 finishes energy-saving mode, switches to normal mode.Then, master control part 10 finishes this control.
On the other hand, when be judged to be relay on-off action decision signal not with cycle of AC power to seasonable (step S111: no), enter step S113, be judged to be relay contact 21 and produced open failure.Master control part 10 enters step S114 after step S106 and step S113, reported the electrical leakage breaking function generation unusual in demonstration/operating portion 52.The concrete grammar that carries out this report is not particularly limited, and for example, as described above, reports with LED or liquid crystal display part etc. to get final product.Particularly, can be used as LED of lighting when unusual etc. and report, also can in liquid crystal display part, report that in the mode of Word message or image information there is unusual situation in the electrical leakage breaking function.And, also can send alarm sound or warning message as acoustic information.Namely, in the on-off action of relay mechanism 20, produced in the unusual situation, as long as master control part 10 can report that to the user there is unusual situation in the electrical leakage breaking function by the report device, report that then the structure of device and method for reporting can use known arbitrary structures and method.Then, master control part 10 finishes this control.
In addition, master control part 10 control that also can stop at the molar behavior that receives the electrical leakage breaking function and produce the unusual laggard enforcement seat device 50 of this judgement.That is, also can in the result of validation test in the switching of relay mechanism 20, detecting unusual or master control part 10 has produced control when unusual, stop the molar behavior of seat device 50.Thus, can further improve user's security.
Like this, according to the present invention, by cutting down the power consumption of never cutting down up to now the electrical leakage breaking section of object as stand-by electric, can further realize energy-saving effect thus.
Can use seat device of the present invention is all seat devices with electrical leakage breaking section of said structure, particularly preferably is applied to " moment formula " clean washing apparatus.So-called " moment formula " clean washing apparatus refers to have above-mentioned " moment supplying hot water " and the clean washing apparatus of " transient heating toilet seat ", and it is power consumption just in use only, thus, can reduce electric power consumption, the raising energy saving.In this " moment formula " clean washing apparatus, although fully cut down stand-by electric,, by using the present invention, can save the power consumption of electrical leakage breaking section, so, energy-saving effect can further be obtained.
For example, when for the applicant's seat device in the past with used seat device of the present invention, when carrying out the estimation of fractional energy savings (energy-conservation realization benchmark) in 2012 years of in electric toilet seat field, being formulated by Japan's Economy, Trade and Industry Ministery, the fractional energy savings of seat device in the past is 167%, relative therewith, the fractional energy savings of seat device of the present invention brings up to 175%.In addition, energy-conservation realization rate is to utilize " the energy-conservation a reference value of energy consumption efficiency ÷ of this product * 100 " this calculating formula to calculate.Therefore, if realized the energy consumption efficiency identical with energy-conservation a reference value, then energy-conservation realization rate is 100%, if surpass energy-conservation a reference value, then energy-conservation realization rate surpasses 100%.
Utilizability on the industry
As mentioned above, according to the present invention, can further improve the energy saving of seat device.Therefore, the present invention can be fit to be applied to heat the field that toilet seat, warm water clean the various seat devices such as toilet seat and clean washing apparatus very much.
