Description

Be used to clean the device of lower part of humanbody

Technical field

The application of this division be the applicant on April 1st, 1998 submit to, application number is 98803853.6, denomination of invention is divided an application for " being used to clean the device of lower part of humanbody ".

The present invention relates to a kind of lower part of humanbody cleaning device that cleans human body with hot water.

Background technology

This traditional lower part of humanbody cleaning device is as being disclosed in shown in Figure 28 in Japanese patent gazette 5-33377 number (1993).Figure 28 is the schematic diagram that the rinse water feed system is shown, and wherein feed pipe 152 links to each other with the upstream side of pump 151, and air mixing portion 153 mixes with the downstream of pump 151.Air mixing portion 153 comprises the cylindrical suction head 154 of a pottery system, and the feasible air of sending here from compressor 155 is sneaked in the water suction head 154.By this layout, the rinse water pressurization of being supplied with from feed pipe 152 by 151 pairs of pumps also makes rinse water enter air mixing portion 153.In air mixing portion 153, the air of supplying with from compressor 155 is divided into very thin part so that flow into rinse water.Then, flowed through the rinse water of air mixing portion 153 enters heat interchanger 156.The rinse water that is heated to proper temperature by heat interchanger 156 supplies to spray nozzle device 157 so that spray to lower part of humanbody.By this function, the rinse water that sprays from spray nozzle device comprises air, so, when cleaning lower part of humanbody, obtain gentle sensation of stroking health.

But in above-mentioned traditional lower part of humanbody cleaning device, the control of the control of compressor 155 and heat interchanger 156 is not associated with each other.Therefore,, then gathered a large amount of air, so in heat interchanger 156, cause local boiling or unusual heating if the ratio of the amount of the amount of rinse water and air is inappropriate.Simultaneously, because the control of compressor 155 and the control of heat interchanger 156 are not whole control, the user should carry out a plurality of operations, and can not the traditional lower part of humanbody cleaning device of complete operation, unless the user is very skilled to operating sequence and sequential corresponding to various situations.In addition, this problem makes and can not take any measure that cuts down the consumption of energy.

Simultaneously, because air bubble merging when air mixing portion 153 enters spray nozzle device 157 mutually, so diameter becomes bigger, and the rinse water of heat spray off and on from spray nozzle device 157, therefore causes uncomfortable feeling when use or sputter clean water.In addition, can not reduce heat by the heat dissipation that reduces heat interchanger 156, this is very inconvenient.

Traditionally, the geyser that generally will be used for the lower part of humanbody cleaning device is divided into the hot type hot-water storage type and instant, the hot-water storage type be the water of in water tank, storing fixed amount, heat always and be kept at suitable temperature by heater, immediately hot type is the water that adds heat supply immediately, makes the water that is heated to proper temperature send.The geyser of hot-water storage type is as being disclosed in shown in Figure 29 in Japanese patent gazette 2-3860 (1990) number.In Figure 29, lid 163 is securely fixed in the upper open end of the hot-water storage water tank 161 of geyser 162 by the securing member (not shown).Water inlet pipe 164 is connected on the lid 163.One end of water inlet pipe 164 links to each other with the watering (not shown) by feed pipe 165, and the other end of while water inlet pipe 164 passes near the bottom that lid 163 extends to hot-water storage water tank 161.Hot water discharge section 166 is connected on the lid 163 and has hot water outlet 166a with hot-water storage water tank 161 internal communication.Be used for adding the heater 167 of hot water by lid 163 insertion hot-water storage water tanks 161.Simultaneously, the temperature pick up 168 that is used to detect the hot water temperature is installed in lid 163, makes TEMP part 168a insert in the hot-water storage water tank 161.The power supply of the temperature control heater 167 of the hot water that detects according to temperature pick up 168 makes that the hot water in the hot-water storage water tank 161 always remains on such as about 40 degrees centigrade Current Temperatures.

But, in traditional hot-water storage type geyser of above-mentioned layout,, supply with the hot water with Current Temperatures surpasses the hot water of storing up to the amount of the water of discharging amount because the amount of the hot water of storing is restricted.Yet the amount of the water of discharging surpasses the amount of the hot water of storing if this geyser uses the so long time, and the temperature of hot water begins progressively to descend.Promptly, if the amount of the water of discharging surpasses the amount of the hot water of storing, discharge from hot-water storage water tank 161 by heater 167 heating and most of hot water of being stored in the hot-water storage water tank 161, and begin to discharge the water that has flowed in the hot-water storage water tank 161 behind the hot water and also discharge.As a result, the temperature of the hot water of discharging from hot-water storage water tank 161 begins progressively to descend.This situation is because the water that has flowed in the hot-water storage water tank 161 is heated near the Current Temperatures after bringing into use hot water immediately to a certain extent, almost is not heated just and is discharged from but flow into water in the hot-water storage water tank 161 subsequently.Therefore, because the low hot water of delivery ratio Current Temperatures feels under the weather the user when cleaning health.Therefore, hot-water storage type geyser 162 has some shortcomings like this, promptly, can not clean human body satisfactorily, unless scavenging period shortens and uses geyser 162 off and on hot water with proper temperature owing to can only use geyser 162 discharging under the short situation of hot water time.

Under the bigger situation that the hot-water storage water tank 161 of hot-water storage type geyser 162 can not be made, in order to address the above problem, people adopted a kind of in Japanese Utility Model communique 1-42757 (1989) number disclosed instant hot type geyser, as shown in figure 30.Geyser 179 shown in Figure 30 constitutes with the hot-water storage cylinder 181 that forms hollow cylindrical by forming columniform METAL HEATING PROCESS water tank 180 with bottom.Heating water tank 180 is contained in the hot-water storage cylinder 181, makes hot-water storage part 181a be limited on the heating water tank 180.The openend of heating water tank 180 fixedly advances in the opening of hot-water storage cylinder 181, makes heating water tank 180 be communicated with hot-water storage cylinder 181 by the through hole 182 on the edge that is formed on the heating water tank 180 of being close to this openend.Then, the hollow cylindrical ceramic heater 183 that comprises the electrons heat element is communicated with the supply channel (not shown), so that the loose fit installation, by printing this electrons heat element of formation on the surface of ceramic heater 183 or between two ceramic substrates.The opening of hot-water storage cylinder 181 is near the flange of ceramic heater 183.Another opening of hot-water storage cylinder 181 makes housing 186 be communicated with hot-water storage cylinder 181 near the housing 186 that comprises drift switch 184 and vacuum switch 185.So, discharge hot water from the hot water discharge pipe 187 who is fixed on the housing 186.The temperature pick up 188 that is used to detect by the temperature of the hot water of ceramic heater 183 heating is installed in above the through hole 182 that is formed on the heating water tank 180.

In instant hot type geyser 179,, can discharge hot water for a long time with fixed temperature owing to can be heated to Current Temperatures to the water that enters heating water tank 180 interior week immediately by the electrons heat element of ceramic heater 183 by ceramic heater 183.On the other hand, be used to prevent that the line breaker of overload current is installed in the room usually.In order to prevent the tripping operation of line breaker, the wattage of heater should be set at and be no more than 1200 watts (W) when 100 volts of (V) alternating currents.Use such as have 40 degrees centigrade (℃) the situation of hot water under, consider that the water temperature of supplying with geyser winter is lower, for 40 degree that water temperature is raise, discharge rate should not surpass 400 cubic centimetres/minute (cc/min).In the instant hot type geyser of above-mentioned layout, along with the diameter of hollow cylindrical ceramic heater 183 further reduces, the production of ceramic heater 183 difficulty more that becomes, and its heat transfer zone becomes littler, like this, the diameter of ceramic heater 183 is restricted.Therefore, in aquaporin, produce the water storage part of water accumulation with heating water tank 180 corresponding to the volume of ceramic heater 183 sizes, hot-water storage cylinder 181 or the like.For example, even discharge rate approximately is 200cc/min, its heat capacity is owing to the water storage part becomes big, and water accumulates in and does not resemble not in the equally little water storage part of the discharge rate that surpasses about 400cc/min, the result, such shortcoming takes place, promptly because not only raise temperature and realize that in temperature control response needs long time, and owing to compare with above-mentioned discharge rate, the cross-sectional area of the inner periphery and the outer periphery flow path of ceramic heater 183 diminishes flow velocity greatly, the coefficient of overall heat transmission descends, thereby causes the thermal efficiency of geyser to reduce.

Simultaneously, except discharging the inconvenience that the hot water time is restricted, the lower part of humanbody cleaning device that comprises above-mentioned hot-water storage type geyser also has following shortcoming, promptly this device becomes very big owing to the hot-water storage water tank makes size, also owing to provide power supply for a long time so that this device can use at any time all day, because the energy consumption that heat dissipation produces when storing hot water has occupied the major part that whole energy consumes, so cause running cost to increase greatly.On the other hand, the lower part of humanbody cleaning device that comprises the instant hot type geyser of above-mentioned layout has following shortcoming, promptly because the volume of heating water tank becomes big owing to the size of hollow cylindrical ceramic heater, be difficult to make this device compact, and owing to, during cleaning, be difficult to the instant design temperature that changes because of the water storage part makes control response very slow.

In addition, a kind of traditional flow sensor and a kind of lower part of humanbody cleaning device that comprises flow sensor are disclosed, as shown in figure 31 in Japanese patent gazette 6-264486 (1994) number.Below with reference to Figure 31 traditional flow sensor is described.Figure 31 is the cross-section front view of flow sensor.In Figure 31, flow sensor 201 is made up of impeller 206 and an optical chopper 207 of being installed in axle 205 rotational support on the body 204 body with inflow path 202 and outflow path 203 204, one.Optical chopper is placed on and makes the position of its optical axis through side plate 208 edges of setting on impeller 206.Light is blocked by side plate 208 but by a plurality of recesses 209, recess 209 is formed on the edge of side plate 208 with the spacing that equates, can detect the revolution of impeller 206 like this.

Simultaneously, Figure 32 is the piping diagram that comprises the lower part of humanbody cleaning device of this flow sensor.In Figure 32, the hot-water storage water tank 212 that heater 211 is housed links to each other with the downstream of supply-water pump 210.Simultaneously, be used for linking to each other through the downstream of flow sensor 201 with hot-water storage water tank 212 to the washer jet 213 of lower part of humanbody jet cleaning water.Draw on the variable basis of self-flow rate sensor 201 driving voltage of controller 214 control supply-water pumps 210 at the flow velocity of representing by the revolution of impeller 206 and its.

But, in the flow sensor of known Figure 31, flow to outflow path 203 from inflow path 202 straight lines owing to be used for the rinse water of wheel rotor 206, be used for the fluid force deficiency of wheel rotor.Therefore, when lower flow velocity, impeller 206 may not rotate, perhaps adversely unstable the rotation.Simultaneously, if air bubble sticks on the impeller 206 with certain form or other form, then air bubble combines because of impeller 206 rotates the centrifugal force that produces in the center of rotation of impeller 206, just produce such problem, promptly be difficult to the vent the air overboard bubble, and it is unstable that the rotation of impeller 206 becomes, and therefore causes detecting the precise decreasing of flow velocity.

Simultaneously, in traditional lower part of humanbody cleaning device shown in Figure 32,, just cause the loss of energy consumption by heat dissipation owing to always provide power supply to heater 211 for the temperature that remains on the rinse water in the hot-water storage water tank 21.In addition, owing to the air in the water that is dissolved in the hot-water storage water tank 212 may occur with air bubble when heating, and air bubble inflow flow sensor 201, the flow speed value of detection is owing to the problems referred to above produce very big error.

The specific embodiment

Most preferred embodiment of the present invention is described below with reference to accompanying drawings.

(first embodiment)

Fig. 1 shows the lower part of humanbody cleaning device according to first embodiment of the invention.In Fig. 1, the water of supplying with from feed pipe 8 is used to regulate that the motor-driven flow control valve 10 of amount of rinse water and one are used to detect the flow of rinse water and the flow sensor 11 as flow detector of flow velocity enters an instant hot type geyser 12 (that is the heater that can heat water continuously Current Temperatures in water flows process described in " background technology ") by a main solenoid valve 9, one.Main solenoid valve 9 and flow control valve 10 are all as water supply control apparatus.Be provided with one in the geyser 12 in case detect the temperature anomalies of geyser 12 itself and raise just directly to cut off the high limit switch 13 of the power supply of geyser 12 and one are used for detecting the air detection the thermistor 14 whether water of geyser 12 exists.The hot-water line 15 in proximity thermal hydrophone 12 exits is provided with the hot water thermistor 16 that is used to detect the hot water temperature.Washer jet unit 18 links to each other with the end of hot-water line 15, and the end of washer jet unit 18 is provided with the washer jet 17 as discharger.By stretching of an Electric Machine Control washer jet 17.Between washer jet 17 and geyser 12, air is sneaked in the rinse water by air hose 20 as the motor-driven air pump 21 of air mixing device by one.Be used to clean the lower part of the body that is sitting in the user on the toilet seat from the water of washer jet 17 ejections.Toilet seat 22 is provided with a seat attitude switch 23 that is used to detect the seat attitude of the user on the toilet seat 22.

Send the order that is used to realize infeeding rinse water from washer jet 17 from remote control unit 24.Remote control unit 24 has adjusting part 28 that shutdown switch 27, one that bidet cleaning switch 26, one that an anus cleaning switch 25, one be used to clean female genitalia be used to stop rinse water be used to regulate flow velocity and rinse water temperature and one and is used for an adjusting of regulating part 28 is converted to the temperature of rinse water or the changeover switch 29 of flow velocity.Anus cleaning switch 25 and bidet cleaning switch 26 each all as cleaning setting device and selecting arrangement, and shutdown switch 27 is as cleaning setting devices, and also as being used for the flow monitor that the indirect detection rinse water flows and stops.Simultaneously, in Fig. 1, only show the cleaning nozzle device 18 that is used for the anus cleaning, also be provided with the cleaning nozzle device that is used for the bidet cleaning, but do not show with similar structures.

Simultaneously, controller 32 receives from remote control unit 24 radio signals, and each element of linking to each other with controller 32 of control, and is shown in dotted line.Controller 32 has an air blending ratio controller 30 that is used to control air and rinse water blending ratio and one and is used for based on the flow speed controller 31 of realizing control from the signal of flow sensor 11.Controller 32 is provided with a preheating switch 33, is used for selecting heating at geyser 12 when water or hot water do not flow.

Fig. 2 shows the thin portion of geyser 12.The ceramic heater 34 that is used to carry out electrons heat is clamped between copper coin 35 and 36, and each resin-case 38 and 39 that all has interior flow diameter is arranged on copper coin 35 and 36 outsides.These housings 38 and 39 are pressed against on copper coin 35 and 36 by sealing medium 40.Simultaneously, high limit switch 13 links to each other with the surface of copper coin 35, and air detection thermistor 14 is fixed on the top of housing 38.

Fig. 3 and Fig. 4 show the thin portion of washer jet 17.Fig. 3 is the vertical view that the washer jet of seeing from above 17 is shown, and Fig. 4 is the partial cut away side views of washer jet 17.The cross-sectional area of the flow path in washer jet 17 reduces to the flow path 42 and 43 the washer jet 17 gradually from the flow path 41 of washer jet unit 18, then, extend to amplifier section 46 through parallel portion 45, the width of amplifier section 46 increases gradually to spray nozzle part 44.By this layout, when infeeding the hot water that is mixed with air, rinse water is discharged to lower part of humanbody, simultaneously because swing in the scope that acts on a relative broad of effect that air mixes and amplifier section 46.That is, when hot water when parallel portion 45 enters amplifier section 46, hot water is attached on the relative wall, this is the Coanda phenomenon, the air that this Coanda phenomenon is subjected to sneaking in the hot water disturbs arbitrarily, makes the current teeter that infeeds.When stopping in hot water entrained air, because the effect of parallel portion 45 is discharged hot water straight line in the scope of relative narrower.By utilizing this phenomenon whether to select entrained air in hot water, can infeed the cleaning current by conversion between oscillating motion and rectilinear motion.

Fig. 5 shows the thin portion of air detection thermistor 14.Around the bead 47 of protection tube 48 protection thermistors, between bead 47 and protection tube 48, insert filler 49 and seal.By anchor clamps fixedly protection tube 48 make it to stretch in the flow path of hot-water line 15.It is as follows that sky in this air detection thermistor 14 detects principle.At first, measured temperature in advance after, to air detection thermistor 14 supply of electrical energy own with heating air detection thermistor 14.One through the scheduled time, just measures temperature once more and compares with temperature before the heating.When air detection thermistor 14 was surrounded by water (hot water), the heat dissipation after the heating was relatively large, and therefore, the temperature difference before and after the heating is very little.If air detection thermistor 14 is surrounded by air, then the heat dissipation after the heating is less relatively, and therefore, the temperature difference before and after the heating is very big.On the basis of this temperature difference, judge whether air detection thermistor 14 is surrounded by water (hot water) or air.In order in a series of controls, to judge accurately,, be set to heat time heating time long or short along with the height of temperature before the heating.Simultaneously, the decision of whether being surrounded by water or air about air detection thermistor 14 is to carry out on the basis of the temperature difference before and after the heating, so that reduce the influence of ambient temperature.

The operation of the lower part of humanbody cleaning device of this embodiment is described with reference to Fig. 6.When in step S1, connecting power supply and anus cleaning switch 25 when step S2 is operated, sit the attitude switches if connect by barrel seat ring 22 of riding a horse by the user at step S3, program circuit proceeds to the step S4 of the temperature decision of hot water thermistor 16.Controller 32 is lower than or is not less than 50 degrees centigrade of judgements of predetermined temperature according to the temperature that is detected by hot water thermistor 16 is danger or safe.When judgement was in danger, next step did not just discharge rinse water to human body.By this judgement, prevent from high-temperature-hot-water is discharged from washer jet 17 to human body.Therefore, guaranteed to prevent any dangerous safety that takes place.Simultaneously, in use, if owing to the temperature control system of geyser 12 breaks down or the amount of rinse water descends suddenly and makes the temperature of hot water be not less than 50 degrees centigrade, hot water thermistor 16 detects these, stops to supply with hot water by main solenoid valve 9 immediately.Then, start air pump 21, open main solenoid valve 9, progressively stretch out washer jet 17 at step S7 at step S6 at step S5.For the refluence of anti-sealing,, also to earlier start air pump 21 even air pump 21 inspection bodies own break down.By this function, can prevent when use starting because air pump is advanced in the refluence of water or hot water makes performance descend or break down.

Then, soon, in the value of step S8 reading flow speed sensors 11.If surpass 0.2 liter/minute at step S9 flow velocity, controller 32 is judged has water to flow, and begins to geyser 12 supply of electrical energy at step S10 like this, by the hot heated wash water of ceramic heater 34 generations., at step S11 read in flow speed value that remote control unit 24 set, and control flow control valve 10 by this setting value is compared with the value that is detected by flow sensor 11, so that obtain the flow velocity of setting value at step S12 thereafter.

Then, control imposes on the voltage of air pump 21 on the basis of flow sensor 11 read values, so that make the ratio of the amount of the amount of sneaking into the air in the rinse water and current rinse water be assumed to be a predetermined value at step S13.The revolution of the motor of air pump 21 is along with voltage change, thus from the air capacity of the discharge of air pump 21 also along with voltage change.The amount of rinse water has been shown among Fig. 7 and has sneaked into the relation of the amount of the air in the rinse water.Under the situation of cleaning anus, the air blending ratio increases along with the minimizing of the amount of rinse water.If the air blending ratio increases, owing to following reason, the diameter of air bubble is easy to increase along with the minimizing of the amount of rinse water.That is, by the flow velocity of flow control valve 10 in cleaning water inlet restriction rinse water.Therefore, if the flow velocity of rinse water reduces, in the interior drops of the rinse water at washer jet 17 places, like this, even sneak into rinse water with the air of the same amount of the air that is used for a large amount of rinse water, it is bigger that the diameter of air bubble also may become.

Usually, increase, stimulate the sensation of health to strengthen, and cleansing power also strengthens if having the amount of large diameter air bubble.But, if the quantity of air bubble sharply increases, being easy to spray off and on, a lot of users dislike.In anus cleans,, pay the utmost attention to cleansing power and control, make the air blending ratio along with the minimizing of the amount of rinse water suitably increases for this situation.In bidet cleaned, a lot of users tended to estimate that the moistening sensation of the lower part of the body is stronger than the cleaning performance of rinse water itself.Therefore, in bidet cleans, control and make the air blending ratio reduce along with the minimizing of cleaning the water yield.In a word, automatically change because the amount of sneaking into the air in the rinse water can respond the control of rinse water flow velocity, the user needn't carry out a plurality of operations, operating sequence and sequential under also needn't on top of various situations, like this, even also can following one's bent, old man and child use this device.

Thereafter, for the temperature of the rinse water that obtains to need, the temperature that controller 32 is set remote control unit 24 and the temperature of hot water thermistor 16 relatively so that regulate the heat that adds of geyser 12 at step S14.Under the situation of the design temperature that will change rinse water, being used in remote control unit 24 realizes that between flow velocity and temperature the changeover switch 29 of conversion is transformed into temperature, so that regulating part 28 adjusting temperature.Simultaneously, will change under the setting flow rate conditions, changeover switch 29 is transformed into flow velocity, so that regulating part 28 adjusting flow velocitys.Be changed if set flow velocity, the amount of sneaking into the air in the rinse water responds the flow velocity of aforesaid rinse water and changes.Therefore, can prevent, and cause rinse water to be advanced in the air pump 21, and make the temperature anomaly of ceramic heater raise to refluence owing to air pump 21 does not rotate owing to the rapid refluence of sneaking into the air in the geyser 12 that descends and cause of the amount of air.Simultaneously, body sense and cleansing power are adapted, and the user can accurately use this device and need not carry out a plurality of operations.

Be adjusted to by flow control valve 10 and set flow velocity and to enter washer jet unit 18 by the hot water that geyser 12 is adjusted to design temperature.In washer jet unit 18, sneak in the hot water by the air of supplying with from the air hose 20 of air pump 21, then, hot water is discharged into lower part of humanbody from washer jet 17.Cleaning under the situation of lower part of humanbody with the hot water that is mixed with air, because the function of washer jet 17, hot water is swung in the scope of a relative broad of lower part of humanbody and is cleaned lower part of humanbody.Compare with the conventional situation of only cleaning with hot water, can clean with half flow velocity that is not higher than under the conventional situation, cleansing power and user's somatosensory can not descend yet.This is also verified by experiment.

Simultaneously, owing to adopted instant hot type geyser 12, eliminate the loss that causes owing to heat dissipation during the hot-water storage in traditional hot-water storage type heater, made energy consumption can be half of traditional heating device.Also, significantly reduced energy consumption because flow velocity can be half the feature under the conventional situation.If consider to supply with the lower season of temperature of water, instant hot type geyser requires the rated value of about 2.5 kilowatts (25 amperes) usually, because general household plug outlet socket is restricted to 15 amperes, is difficult to use geyser.But, in the present invention,, can use general plugs and sockets because geyser 12 only requires 1.2 kilowatts.Simultaneously,, can prevent that air is retained in the geyser 12, therefore, can prevent local boiling and unusual heating in geyser 12 because the air pump 21 that air is sneaked in the hot water is arranged between geyser 12 and the washer jet 17.

Continue by geyser 12 heated wash water and by air pump 21 entrained airs at step S15, up to operation shutdown switch 27.Sending by shutdown switch 27 under the situation of ceasing and desisting order, at step S16, stop to be fed to the power supply of geyser 12, so that cut off the electric energy that is fed to ceramic heater 34.In this shut-down operation, flow sensor 11 do not reach predetermined 0.18 liter/minute stop to cut off the power supply that is fed to ceramic heater 34 according to ceasing and desisting order of shutdown switch 27 before the value, guaranteed safety like this.That is, when beginning to flow, controller 32 begins supply of electrical energy above predetermined value by detecting a signal from flow sensor 11.Simultaneously, flowing when stopping, controller 32 promotes shutdown switch 27 and stops power supply by detecting.As a result, controller 32 not only begins energy supply after water flows to ceramic heater 34 really, and stops energy supply before water stops to flow.In this case, shutdown switch 27 is as indirect flow monitor.In addition, compare from the situation that the signal of flow sensor 11 stops to be fed to the electric energy of ceramic heater 34 with response, ceramic heater 34 can be earlier stopped, and because the order influence that stops to flow, the delay heating that waste heat causes can be reduced and the temperature that produces raises.

Then, flow after the delay heating that the scheduled times have prevented that waste heat from causing by geyser 12, stop main solenoid valve 9 at step S17 by making water.Then, stop, and washer jet unit 18 is when having lost cleansing power, in 17 withdrawals of step S18 washer jet when flow sensor 11 detects the rinse water of supplying with washer jet unit 18.After having stopped main solenoid valve 9, operation 21 scheduled times of air pump,, then, stop air pump 21 at step S19 so that discharge the high-temperature-hot-water of the delay heating generation that causes by waste heat.In use because under the situation that conveying is mixed with the water of a large amount of air or the time-out water that supplies water has stopped flowing, flow sensor 11 detects flow velocity not above 0.18 liter/minute, so that stop being fed to the electric energy of ceramic heater 34, thereby avoid under anhydrous situation, heating and the temperature anomaly rising.Simultaneously, under situation about raising owing to the controller 32 invalid hot water temperatures of making, high limit switch 13 is set in 60 degrees centigrade, and its function is the main power source that cuts off normal type main solenoid valve 9, so that close main solenoid valve 9, thereby stops to supply with hot water.

Under the situation of preheating heat hydrophone 12, whether the air that is detected in the geyser 12 by air detection thermistor 14 exists at first when not supplying with hot water.If air detection thermistor 14 is surrounded by air, then not when geyser 12 is supplied with water, not to geyser 12 energy supplies.Simultaneously, when not opening preheating switch 33,34 pairs of geysers 12 of ceramic heater do not carry out preheating.Reach 40 degrees centigrade predetermined temperature up to the temperature that detects by hot water thermistor 16, just carry out preheating, be rapidly heated so that when operating again, realize.

Promote bidet cleaning switch 26 and supply with, so repeat no more with to stop hot water identical with the mode that above-mentioned anus cleans.As previously mentioned, the bidet feature of cleaning is that the minimizing with the amount of rinse water of control blending ratio formula reduces.

In this embodiment, adopt an example of the instant hot type geyser of geyser 12 conducts that comprises ceramic heater 34.This heater also can be by replacing such as sheathed heater and heating tape other electronic heating apparatus by the isolated heater of mica.Simultaneously, also can use the combustion heat to replace electrons heat.

Simultaneously, near the hot water thermistor 16 that is provided with geyser 12 outlets is as a near example of the temperature-detecting device the heater.Temperature-detecting device can be arranged in the interior flow diameter of geyser 12 or be installed on copper coin 35 or 36.Simultaneously, except thermistor, also can adopt any other temperature-detecting device such as thermocouple and metallic resistance.

Simultaneously, adopt main solenoid valve 9 and flow control valve 10 as an example of water apparatus for controlling of supply, also can adopt an independent main solenoid valve, flow control valve or water pump with independent setting of water hold function also can be used as the water apparatus for controlling of supply.

Simultaneously, adopt the washer jet 17 of hot water, but the non-oscillatory washer jet of hot water or the shower of only discharging the hot water of entrained air also can be used as discharger along with the air swing of sneaking into.

Simultaneously, adopt the example of air pump 21, replace but also can or be arranged on compressed air hair-dryer at a distance by compressor, blast fan with centralized system as air mixing device.

Simultaneously, be used for directly detecting the example of the flow sensor 11 of flow velocity, but also can replace by the indirect flow monitor of the signal of the revolution of opening degree that detects flow control valve or supply-water pump as flow monitor.

Simultaneously, employing is used for directly detecting the flow sensor 11 that water flows and is used for shutdown switch 27 that indirect detection water a flows example as the flow monitor that is used to detect water or hot water flow, but the flow monitor such as flow rate switch or pressure switch also can be used as flow monitor.

Simultaneously, adopt the example of air detection thermistor 14, but the method that also can be existed by method, the method that detects composition of air and the light detection air that horizontal plane is detected by electrode or buoy replaces as the air detection device.

Simultaneously, employing is arranged on shutdown switch 27 on the remote control unit 24, anus cleaning switch 25 and bidet cleaning switch 26 as an example that cleans setting devices, but the switch valve that directly opens and closes the flow path of feed pipe and hot-water line also can be used as the cleaning setting device.

Simultaneously, adopt anus cleaning switch 25 and bidet cleaning switch 26 a example as selecting arrangement, but selecting arrangement can be installed to can selecting the position of the lower part of the body according to disease or any air blending ratio of selecting the same position of the lower part of the body of health status.

(second embodiment)

Fig. 8, Fig. 9 and Figure 10 are respectively phantom drawing, drawing in side sectional elevation and the longitudinal sectional drawings according to the geyser that adopts in the lower part of humanbody cleaning device of second embodiment of the invention.In Fig. 8-10, geyser main body 61 is by constituting as plate heater and the ceramic heater 62 and the pair of metal heat exchange section 64 that are substantially disposed in core.On a surface of the heat exchange section 64 that contacts with ceramic heater 62, apply silicone agent 63,, make ceramic heater 62 be clamped between the heat exchange section 64 so that improve heat conductivity therebetween.In ceramic heater 62, the metallic heating element 65 that produces Joule heat by supply of electrical energy is clamped between a pair of rectangular ceramic plate of being made by alumina or similar item 66, whole then calcining.Lead 67 links to each other with the opposite end of heating element 65.Simultaneously, in each heat exchange section 64, tortuous aquaporin 69 with a plurality of sweeps 68 is formed in the cross section at the basic center parallel with ceramic heater 62, and is communicated with water inlet 70 and the hot water outlet 71 that is opened on an end surfaces of each heat exchange section 64.The hot water outlet 71 of a heat exchange section 64 links to each other by a pipe 72 with the water inlet 70 of another heat exchange section 64.

By above-mentioned device, when water is introduced into the water inlet 70 of a heat exchange section 64 and by lead 67 during to ceramic heater 62 supply of electrical energy, the heat that is produced by heating element 65 is passed to heat exchange section 64 by ceramic wafer 66 and silicone agent 63, flows to water the geyser so that be sent to from water inlet 70.Because when water is heated when the 72 tortuous aquaporins 69 from a heat exchange section 64 in series flow to the tortuous aquaporin 68 of another heat exchange section 64 by managing, water is converted into hot water in the short time of geyser main body 61 of flowing through, like this, hot water is discharged from hot water outlet 71.

Therefore, because geyser main body 61 is instant hot type geysers, the water of supplying with continuously from water inlet 70 is heated immediately, and the hot water with fixed temperature can flow out continuously for a long time.Simultaneously,, can guarantee very big area of heat transfer, and can increase the flow velocity of water, make heat transfer rate increase by the cross-sectional area that reduces tortuous aquaporin along the length of wall because the wall of tortuous aquaporin 6 is heat transfer surface.Therefore, geyser can reach higher load, and is simple in structure compacter, thermal efficiency height.In addition, owing to there is not the water storage part, the heat capacity of water is very little, from bringing into use geyser very high to the temperature rising speed the actual outflow of the hot water with proper temperature, providing controller so that the user is changed under the situation of the temperature of hot water and flow velocity etc., the control reaction also is improved.

By said apparatus, when water is introduced into water inlet 70 and during to ceramic heater 62 supply of electrical energy, ceramic heater 62 is made by alumina, and alumina is a kind of electrical insulator and has big heat conductivity that the programming rate of heater itself is very fast.As a result, owing to can heat up and respond the temperature control of hot water at short notice, and tortuous aquaporin 69, directly contact with ceramic heater 62 from the water that water inlet 70 flows to geyser.Therefore, programming rate and response can be further improved, also the thermal efficiency can be improved.At this moment, because water and heating element 65 are electric insulations, geyser can be worked under the situation of leakproof and short circuit.

(the 4th embodiment)

Figure 12 and 13 is respectively phantom drawing and the horizontal sectional drawing according to the geyser that adopts in the lower part of humanbody cleaning device of fourth embodiment of the invention.Corresponding with the element among the element that has same numeral among Fig. 8-10 and Fig. 8-10, therefore save detailed description.In Figure 12 and 13, catalytic combustion burner 74 is as plate heater and by cartridge 75, volume part 76, flat fuel channel 78, catalytic combustion part 79, form with exhaust opening 80, cartridge 75 is used for supplying with such as propane, the hydrocarbon fuels of butane and methyl alcohol and so on, volume part 76 is used to make the fuel of supplying with from cartridge 75 evenly to flow, flat fuel channel 78 comprises that two crooked become the metal sheet 77 that protrudes upward in the tabular mode as corrugated sheet and the volume part 76 below being positioned at catalytic combustion burner 74, form each catalytic combustion part 79 on the metal sheet 77 by the catalyzer (not shown) is applied to, exhaust opening 80 is used to discharge burnt gas.Pair of metal heat exchange section 64 is bonded to respectively on the opposite flank of fuel channel 78, so that the easier fuel channel 78 that transfers heat to obtains geyser thus.

By above-mentioned device, the fuel of supplying with from cartridge 75 enters the fuel channel 78 by volume part 76, and fuel channel 78 is clamped between a pair of heat exchange section 64.The fuel that enters in the fuel channel 78 directly contacts with catalytic combustion part 79, and the gap between the metal sheet 77 of flowing through simultaneously, and under the effect of catalyzer generates heat by the oxidation reaction of carrying out with airborne oxygen, discharges burnt gas from exhaust opening 80.At this moment, introduce heat exchange section 64 in the heat that catalytic combustion part 79 generates by the wall surface of metal sheet 77 and fuel channel 78, and be delivered to from the water that water inlet 70 is introduced the geyser, simultaneously, the tortuous aquaporin 69 that current form through the basic core at each heat exchange section 64, make water be converted to have the hot water of proper temperature, like this, discharge hot water from hot water outlet 71.As a result, can make the geyser of the compactness of instant hot type, wherein use the fuel such as hydrocarbon with simple structure.Simultaneously, owing to utilize catalytic combustion, needn't carry out oxidation reaction under very high temperature, can not produce at high temperature nitrogen oxide etc., therefore, geyser is discharged the waste gas of cleaning.

(the 5th embodiment)

Figure 14, Figure 15 and Figure 16 are respectively phantom drawing, drawing in side sectional elevation and the longitudinal sectional drawings according to the geyser that adopts in the lower part of humanbody cleaning device of fifth embodiment of the invention.Corresponding with the element among the element that has same numeral among Fig. 8-13 and Fig. 8-13, therefore save detailed description.In the drawings, the watering (not shown) of a pair of resin heat exchange section 64 links to each other with the feed pipe 82 with component 81 with each water inlet 70, and two hot water outlets 71 with have the hot water discharge pipe 84 who converges part 83 and link to each other.In each heat exchange section 64, water inlet 70 and hot water outlet 71 are adjacent to each other, tortuous aquaporin 69 is communicated with water inlet 70, hot water outlet 71 is opened on the surface with the heat exchange section 64 of ceramic heater 62 adjacency, and inflow path 85 is near water inlet 70, outflow path 86 is near hot water outlet 71, and they are located adjacent one another and parallel, and are connected to each other by sweep 68.As the copper coin 87 of heat transfer plate by O shape ring 73 by overall fixed on heat exchange section 64, and seal the tortuous aquaporin 69 of this opening, make the situation that water leaks from tortuous aquaporin 69 can not take place.A pair of each integral body is provided with the heat exchange section 64 of copper coin 87, by having the TR thin rubber sheet 88 of good heat conductivity, touches less than ceramic heater 62 pressures of tortuous aquaporin 69 with area.

By said apparatus, make the water that supplies to feed pipe 82 from component 81 branch substantially equally, to flow to two water inlets 70.By ceramic heater 62 water is heated to be hot water, water flow through simultaneously inflow path 85 and a plurality of sweep 68.Since this hot water also with the inflow path 85 of the outflow path 86 of contiguous tortuous aquaporin 69 in water carry out interchange of heat, the water that enters tortuous aquaporin 69 is heated rapidly, therefore the temperature difference in tortuous aquaporin 69 reduces.Copper coin 87 with big heat conductivity is also by having reduced the temperature difference of this minimizing in tortuous aquaporin 69 in the diffusion on the cross-sectional direction of copper coin 87.As a result, because temperature becomes evenly in the lip-deep diffusion of ceramic heater 62, can prevent breaking of the ceramic heater 62 that causes owing to hot tensile strength.Immediately be formed up to the edge of ceramic heater 62 when heating element 65, also will form tortuous aquaporin 69, so that cover ceramic heater 62 with the area bigger than the area of heating element 65 as the heating part of ceramic heater 62.Therefore, because hot-fluid is delivered on the element such as the geyser of heat exchange section 64 grades that do not absorbed by water, can prevents that part such as end of geyser from reaching unusual high temperature, so improve the thermal efficiency and safety.In addition, because the water of supplying with can substantially equally be supplied with a pair of heat exchange section 64 to water from component 81 branches as the feed pipe 82 of the upstream of tortuous aquaporin 69, make the hot state of opposite face of ceramic heater 62 become mutually the same.Therefore, owing between the opposite face of ceramic heater 62, do not produce temperature gradient, can prevent because the breaking of the ceramic heater 62 that hot tensile strength causes, so reliability is improved.Simultaneously, under the situation that adopts metal catalytic combustion burner 74 conducts plate heater as shown in figure 12, heater is warpage because hot tensile strength becomes, and also can prevent hot tensile strength in this embodiment.

(the 6th embodiment)

Figure 17, Figure 18 and Figure 19 are respectively according to the phantom drawing of the geyser that adopts in the lower part of humanbody cleaning device of sixth embodiment of the invention, horizontal sectional drawing and sectional elevation figure.Corresponding with the element among the element that has same numeral among Fig. 8-16 and Fig. 8-16, therefore save detailed description.In the drawings, geyser main body 61 has the resin heat exchange section 64 of a water inlet 70 and a hot water outlet 71 by one and forms as the ceramic heater 62 of plate heater.The basic center that ceramic heater 62 inserts heat exchange section 64 in the mode of water-stop, making only has an end of the ceramic heater 62 that has lead 67 to stretch out from heat exchange section 64.

In heat exchange section 64, the inflow path 85 that is provided from water inlet 70 along ceramic heater a side of 62 extend, component 81 is used to be implemented to the branch of the aquaporin of ceramic heater 64, it is as the downstream of inflow path 85, a pair of tortuous aquaporin 69 is positioned at the opposite face place of ceramic heater 62 and is opened on ceramic heater 62, so that water is directly contacted with ceramic heater 62, converging part 83 is used for two tortuous aquaporins 69 are converged in their end, outflow path 86 is used for hot water is introduced hot water outlet 71 from converging part 83, it is positioned at the opposite side of ceramic heater 62, and is relative with inflow path 85.Simultaneously, stationary heat hydrophone main body 61 makes ceramic heater 62 vertical substantially.Water inlet 70 is positioned at the bottom of ceramic heater 62, and inflow path 85, component 81, tortuous aquaporin 69, converge part 83 and outflow path 86 progressively makes progress in this order on updrift side, therefore, hot water outlet 71 is positioned at the top of ceramic heater 62.Tortuous aquaporin 69 also is set to flow downward with the downstream that prevents tortuous aquaporin 69.

Pass through said apparatus, because the programming rate of ceramic heater 62 is very high, and make by alumina, alumina is a kind of electrical insulator and has the big heat conductivity that transfers heat to water, and directly contact with water, can heat up and respond the temperature control of hot water at short notice, and improve the thermal efficiency.Simultaneously and since current by tortuous aquaporin 69 from water inlet 70 to hot water outlet 71 orders upwards the air bubble that the oxygen that dissolves in the water is separated produce takes discharge in the hot water outlet 71 to by buoyancy because water temperature raises.Therefore, owing in discharging the flowing of hot water, do not produce the turbulent flow that occurs because of air bubble, can make the work of water heater safety ground by the stable discharge that keeps hot water.And, can prevent to descend owing to the air bubble in heat exchange section 64 makes the coefficient of overall heat transmission and the thermal efficiency.In addition, because having eliminated the large diameter air bubble of whole formation is retained in the localized heat vibration that causes in the tortuous aquaporin 69 coefficient of overall heat transmission is descended suddenly, can prevent because it breaks significantly reduced the application life of ceramic heater 62, so improved the reliability of plate heater.In addition,, do not produce temperature gradient, like this, can prevent because the breaking of the ceramic heater 62 that hot tensile strength causes, so improved the reliability of plate heater at the opposite face of ceramic heater 62 because water is along the parallel inflow of the opposite face of ceramic heater 62.

(the 7th embodiment)

Figure 20 and Figure 21 are respectively phantom drawing and the schematic diagrames according to the geyser that adopts in the lower part of humanbody cleaning device of seventh embodiment of the invention.Corresponding with the element among the element that has same numeral among Fig. 8-19 and Fig. 8-19, therefore save detailed description.In the drawings, each water inlet 70 of watering (not shown) and a pair of resin heat exchange section 64 links to each other with the feed pipe 82 with component 81, and two hot water outlets 71 with have the hot water discharge pipe 84 who converges part 83 and link to each other.The thermistor 89 that is used for detecting the temperature of discharging hot water is arranged on the part of the downstream heat water discharge pipe 84 that converges part 83.Stationary heat hydrophone main body 61 makes ceramic heater 62 vertical substantially.Owing to form the tortuous aquaporin 69 that is communicated with the water inlet 70 and the hot water outlet 71 of each heat exchange section 64,71 orders upwards from water inlet 70 to hot water outlet, water inlet 70 is positioned at the nethermost substantially position of geyser main body 61, and hot water outlet 71 is positioned at the uppermost substantially position of geyser main body 61.As the heating element in the ceramic heater 62, form heating element 90a and 90b by two circuit with a basic identical power and in parallel electric heater.One end of each in two circuit links to each other with shared lead 91.Simultaneously, the other end in one of two circuit links to each other with lead 92a, and another the other end in two circuit links to each other with lead 92b.Common wire 91 links to each other with controller 93 with 92b with lead 92a, is respectively applied for the electrical power factor that heating element 90a and 90b are supplied with in control.

By said apparatus, 71 orders extend upward tortuous aquaporin 69 from water inlet 70 to hot water outlet.Therefore, even produce air bubble, air bubble also is brought in the hot water outlet 71 and discharges.Therefore, not only can make the work of water heater safety ground by the stable discharge that keeps hot water, and, also can prevent to descend owing to the air bubble in heat exchange section 64 makes the coefficient of overall heat transmission and the thermal efficiency.Simultaneously, owing to eliminated the localized heat vibration that the large diameter air bubble of whole formation causes, can prevent breaking of ceramic heater 62, so improved the reliability of plate heater.In addition, because water is along the parallel inflow of the opposite face of ceramic heater 62, can prevent because the breaking of the ceramic heater 62 that hot tensile strength causes, so improved the reliability of plate heater.In addition, owing to form heating element 90a and 90b by two circuit of the electric heater with a basic identical power and parallel connection, the power of the electric heater of a circuit reduces with respect to the ratio of desired general power with the number opposite with the number of circuit.As a result, be controlled, improved control sensitivity greatly, can carry out precise dose control, reduced thermal vibration, prolonged the application life of electric heater, so improved reliability owing to supply to each electrical power factor with very low power circuit.Simultaneously, under the situation of circulation controlling means, wherein cycle-index obtains adjusting in the control method of scheduled period, and supply with the electrical power factor of electric heater by repeating this control method control, capable of circulation switching on and off has very low power each electric heater, makes the change of voltage of power line be limited very for a short time.As a result, can prevent flashing of illuminating lamp etc., and restriction is to the uncomfortable temperature change of geyser user.

Simultaneously, in this embodiment, in two circuit, be provided with electric heater with equal-wattage.But the number of ifs circuit further increases, and has further improved control sensitivity, can obtain identical effect.Simultaneously, even electric heater does not have essentially identical power, also can obtain similar effects apparently by control method.
