The specific embodiment
(example 1)
Below, with reference to Fig. 1～Fig. 5 the example 1 of toilet apparatus of the present invention is described.
Among Fig. 1, the supply line 1 of feedwater branches out water service pipe 2 towards warm water cleaning device by right angle tap 1a from water-supply source towards closet, feed water to sealing electromagnetic valve 4 by flap valve 3, for unnecessary clean water being released into closet from sealing electromagnetic valve 4, by being provided with the release path 5 of safety valve 6, to formula heat interchanger 7 feedwater of the moment of the heater 8 that is built-in with the rated power about 1.0～1.5kW, this formula heat interchanger outlet of 7 is by having the fluidised form transfer valve 9 of flow regulating function and stream switching mechanism moment, and has that buttocks is cleaned nozzle 11 and lady's ablution nozzle 12 and to these clean nozzles 11, the nozzle unit 10 that 12 nozzles of cleaning are cleaned path 13 connects.
Fluidised form transfer valve 9 comprises: clean the clean mouthful 9b of buttocks that nozzle 11 is connected with water inlet 9a, buttocks; A mouthful 9c is cleaned in the lady's ablution that is connected with lady's ablution nozzle 12; Clean the clean mouthful 9d of nozzle that path 13 is connected with nozzle, by motor 9e the position of rotation of valve body (not shown) is controlled, with the switching and the Flow-rate adjustment of carrying out docking port 9b～9d.
The 14th, closet, the 15th, toilet seat is provided with on toilet seat 15 and detects the take a seat checkout gear 16 of taking a seat of situation of people.In addition, near moment formula heat interchanger 7 outlet, be provided with the temperature-detecting device 17 that the temperature of cleaning water is detected.The 18th, control part, the detection signal of take a seat checkout gear 16 and temperature-detecting device 17, thereby the motor 9e of control sealing electromagnetic valve 4, heater 8, fluidised form transfer valve 9.
In the above structure, when the user takes a seat toilet seat 15, as shown in Figure 2, from the checkout gear 16 of taking a seat to control part 18 detection signal of taking a seat, control part 18 is opened sealing electromagnetic valve 4, fluidised form transfer valve 9 is switched to nozzle clean a mouthful 9d, makes to clean the clean path 13 of current direction nozzle, read the detected temperatures of temperature-detecting device 17 after stipulated time, can detect inflow temperature.
Then, as shown in Figure 3, open sealing electromagnetic valve 4, fluidised form transfer valve 9 is switched to nozzle clean a mouthful 9d, make under the state of cleaning the clean path 13 of current direction nozzle, heater 8 is imported at the appointed time the electric power below 1/2 of rated power, rise to the degree of damaged with temperature under the situation that does not have water in the heating channel of avoiding contingency moment formula heat interchanger 7, for example, for the electric power about the specified input electric power heater 8 input 100W～500W that are 1.0～1.5kW, detect by the variation of 17 pairs of detected temperatures of temperature-detecting device.
Here, when clean water flows, as shown in Figure 3, detected temperatures sharply rises when the adding the clean water of hot flow path after by heater 8 heating and flow to the position of temperature-detecting device 17 of formula heat interchanger 7 moment, so detected temperatures of temperature-detecting device 17, its input life period that rises for heater 8 postpones, and when the input to heater 8 stops, the detected temperatures life period lingeringly sharply descends.Thus, can detect clean water moment formula heat interchanger 7 add this situation that flows in the hot flow path, and can calculate the flow of cleaning water from this time lag D.
According to above-mentioned detected inflow temperature and the flow of calculating, input electric power to heater 8 is controlled, thereby can carry out FEEDFORWARD CONTROL to the temperature that the clean water of nozzle 11,12 is cleaned in initial supply, correctly control from cleaning the temperature of the clean water that nozzle 11,12 discharges.In addition, according to the controlling value of fluidised form transfer valve 9 and the flow-control parameter of the flow change setting fluidised form transfer valve 9 of calculating, thereby can guarantee high-precision flow set.
On the other hand, clean in the mobile absence of water, as shown in Figure 4, even to heater 8 input electric power, heat also can not be passed to the position of temperature-detecting device 17 hastily, and the detected temperatures of temperature-detecting device 17 just changes extremely lentamente, even after this stop the input to heater 8, temperature also continues to rise, thereby can detect the such situation of water of not cleaning reliably.Like this, when clean water does not flow,, can prevent that moment formula heat interchanger 7 sky from burning by forbidding input to heater 8.Do not clean water when detecting, then stop all actions of warm water cleaning device, give the alarm, notice does not have the situation of feedwater.
More than in the explanation, as shown in Figure 3, represented that to the electric power of heater 8 input only carries out 1 time example, but also can be as shown in Figure 5, heater 8 is repeatedly imported on power pulse shape ground, like this, even also having or not of water can be different from noise and detection reliably, when rising, the temperature of inhibition moment formula heat interchanger 7 can prevent empty the burning reliably with respect to the input of heater 8 is little.
(example 2)
Below, with reference to Fig. 6, Fig. 7 the example 2 of toilet apparatus of the present invention is described.But, the composition member identical with above-mentioned example 1 put on same reference marks, and omits its explanation, only difference described.
In this example, near moment formula heat interchanger 7 outlet, the 1st temperature-detecting device 19 that leaving water temperature is detected is set, the pars intermedia that adds heat passage in moment formula heat interchanger 7 is to being provided with the 2nd temperature-detecting device 20, with its detection signal input control part 18 near the import.
In the above structure, in the feedwater control action with respect to nozzle unit, as shown in Figure 7, every reasonable time at interval, electric power by 18 pairs of input heaters 8 of control part changes step-likely, detected temperatures to the 1st and the 2nd temperature-detecting device 19,20 monitors, obtain the time lag d of the variation of detected temperatures, calculate the flow of cleaning water from this time lag d, compare with at that time flow-control value by detecting flow, come the controlling parameter of change setting fluidised form transfer valve 9 with respect to fluidised form transfer valve 9.
Adopt this example, although be the structure that the cheapness of flow transmitter is not set, even but under the situation that the hydraulic pressure change of water-supply source etc. change, also can pass through the controlling parameter of the Flow-rate adjustment of change setting fluidised form transfer valve 9 automatically, required flow is kept all the time accurately.
In this example, use the situation of fluidised form transfer valve 9, supply with in the example of the pump of cleaning water, also can play this effect but be equally applicable to use to nozzle unit 10 as having given the water controller illustration.
In the nozzle unit 10 of above-mentioned example, illustration have nozzle and clean path 13, the situation that water is cleaned is cleaned in the leading section outside ejection of cleaning nozzle 11,12, but also can apply the present invention to have the structure of the sluicing path of drain water in closet 14 merely, obviously can play identical effect.
