Detailed description of the present invention

Cleaning station W1 shows brightly as best among Fig. 1, and a cupboard 10 and a vertical support frame 12 are arranged.It is structural member separately that cupboard 10 and support 12 can resemble shown in the figure, perhaps can be one, and perhaps support 12 can be part of wall or the like.Simultaneously, though we preferably make cupboard 10 and vertical support frame 12 with stainless steel, it is also passable that the skilled person of this technology should be understood other material, for example when cleaning station W1 is used in the environment of restaurant.

Kitchen sink 14 is installed on the top 16 of cupboard 10, and an infrared sensor 18, one water taps 20 are installed on top 16 simultaneously, and a selector switch 22, and cupboard 10 can have handle 24 and 26, opens to allow a

door

28 and 30.

The coil paper applicator 32 of one electricity operation is installed on the vertical support frame 12.The coil paper applicator is preferably according to United States Patent (USP) the 4th, 960, No. 248 manufacturings, the disclosed content of above-mentioned patent is as with reference to being incorporated into the present invention, and its trustee also is the trustee of present patent application.Applicator 32 has an infrared sensor 34, can be the passive type Infrared Detectors, and this is different from the active infrared detection device in the sensor 18.Also show the one section paper handkerchief 36 that from applicator 32, stretches out among Fig. 1, and display 38, display 38 shows the access times of cleaning station W1.Though we preferably use paper handkerchief, if from applicator 32 dispensing one continuous length tear it down dry with material.Should not use the towel sheet, because they have and may the contacted danger of contaminated applicator.

Show brightly as Fig. 2 the best, cupboard 10 has the proper operation element of an open inner space cleaning station W1 all to be positioned at wherein.Hot water and cold water pipes 40 and 42 are to be supplied water by the common water source that is arranged in the great majority building.Manual valve-off 44 and 46 is installed on the upper end of water pipe 40 and 42.One T-type connector or joint 48 water pipe on the valve 44 extends and has a pipeline 50 to extend out from it, and its reason is explained subsequently again.The

solenoid valve

52 and 54 of electricity operation and is inserted between valve 46 and the T-type connector 56 in the water tap 20 so that be in to open or permit when flowing the position at valve 52 and/or 54 water is supplied to water tap 20 respectively between valve 44 and T-type connector 56.Valve 52 and 54 is in closed condition under usual condition, T-type connector 56 mixes mutually to reach temperature required hot and cold water.Water tap 20, such as Fig. 7 the best show brightly, a water stream channel 60 and a built-in soap circulation road 62 are arranged, it ends at ozzle 64 so that water is imported kitchen sink 14, water enters sewer or treatment system from gutter at last.

Horizontal stand 66 is installed within the cupboard 10, and supports to be installed on soap container or the bottle 68 that stresses on the device 70.Pipeline 72 extends to banding valve pump 74 from soap container 68.Pipeline 76 extends to flap valve 78 from pump 74, and pipeline 80 extends to the soap passage 62 of water tap 20 from flap valve 78.Flap valve 79 is on the pipeline 72 and between container 68 and pump 74.Soap passage 62, such as among Fig. 7 the best show brightly, have a short section pipe 82 to extend out soap is imported among the kitchen sink 14 from water tap.

Be positioned at the upstream of pipeline 50 and extend to T-type connector 86 by solenoid operated by-pass valve control 84, and then extend to banding valve pump 74 pressurized water is offered banding valve pump 74.Another outlet of T-type connector 86 extends to a control valve or limiting holes only.Pipeline 92 extends to the T-type connector 94 of pipeline 58 from control valve 90, such as Fig. 3 the best show bright.

Weight-measuring device 70, such as in Fig. 4 and 5 the best show brightly, comprise first gripper shoe 96 of supporting by support 66, and second plate, 98, the second plates 98 that are positioned on the plate 96 are connected to first plate 96 by hinge assembly 100 in the mode of hinge.But soap container 68 is the relative lighter disposal type bottle of weight preferably, and it is supported by second plate 98.Second plate 98 has many grooves 102,104 and 106 to be formed on its surface 108, and they are separated mutually with respect to hinge assembly 100.Pressure switch 110 has a piston 112, and piston 112 can be positioned groove 102,104 selectively, in one of them of 106.Soap container 68 and wherein soap weight thereby affact on the pressure switch 110 by piston 112, thereby in order to the fullness degree of monitoring of containers 68.Electric wire 114 also passes to the quality of soap the container 68 on the central computer, from pressure switch 110 extensions as shown in Figure 12.

We have found that, certain mobility preferably is set when soap container 68 needs to change and notifies central computer.The weight of container 68 works by hinge component 70, and a masterpiece is used on the piston 112, and the distance between this power and piston 112 and the hinge component 100 is proportional.Like this, we are positioning pressure switch 110 and piston 112 thereof selectively, and pressure switch 110 can trigger and open when reaching a set point value with the quality of last soap in the convenient container 68.Like this, in its reaction time, can notify maintenance.The pressure switch that we preferably use is a kind of pressure switch of only just sending appropriate signals when triggering is opened, because it can make the load of central computer minimize.Otherwise central computer just must inquire termly that switch 110 is to determine the quality of soap last in the container 68.Because the cleaning agent in the container all is slow loss as a rule, so the most practical by the switch of pressure actuated.

Figure 4 and 5 also show continuous elasticity carrier pipe 116, and it extends through pump 74 and stretches among the soap container 68.We are provided with a seal disc 118 and spatter outside the soap preventing on the top of container 68, also connect simultaneously and has put the opening that can establish flange, and pipe 116 can insert among this opening.What be worth mentioning among Fig. 5 is that pipe 116 extends through pump 74.Also be necessary to change carrier pipe 116 when changing container.The contaminated possibility of interface or joint just reduces to minimum like this.This is particularly suitable in hospital environment, because should avoid infection as much as possible in hospital.Yet, needn't be like this in the food processing environment.

Coil paper applicator 32, such as in Fig. 2 and 3 the best show brightly, an infrared sensor 34 is arranged.No matter when the user needs paper handkerchief, and sensor 34 all can make motor 120 operations.This is suitable especially in hospital environment, because may before the user finishes a normal cleaning frequency unexpected emergency be arranged promptly sometimes.Motor 120 rotates paper towel roll 122 by one-way transmission device 124.This discharges out from the opening of applicator 32 with regard to guaranteeing paper handkerchief, and prevents that paper towel roll 122 is rolled-up.

We have found that can use many dissimilar pumps with cleaning material 126 pumps to water tap 20.For example banding valve pump (pinch valve pump) 74 has an almost indeformable cylindrical housing 128, shell 128 seals at its two ends, but two openings 130 and 132 are arranged, and opening 130 and 132 is respectively pipe 116 inlet and an outlet is provided, as shown in Figure 5.Done another opening 134 to connect water pipe 80 in a side of shell 128.

Elastic sack body 136 is positioned within the shell 128 and a central opening 138 is arranged, the continuous diameter of opening 138 corresponding with the diameter of pipe 116 in case with pipe 116 close fitting.This close fitting makes the active force of pump reach maximum.Pipe 116 can be thinner relatively simultaneously, and the selection of its thickness can be decided according to the quality of soap to be aspirated 126.The wall of pipe 116 is thick more, and the soap volume that then holds in the suction chamber is just more little.

The skilled person of this technology is appreciated that and will causes water central opening 138 to be squeezed among pipeline 80 imports the doughnut 140 that is defined by utricule 136 and shell 128, thereby pipeline 16 is caved inward.What this was unexpected caves in to the material that is held in the pipeline 116 is outwards pushed.The soap that flap valve 78 allows to be extruded flows to container 68.This extruding action is very fast and cause soap 126 from pipeline 82 ejections.

As long as valve 84 is in opening, utricule 136 will keep swelling state.Thereby in case valve closing is removed the hydraulic pressure source that comes from pipeline 88, so only need valve 90 is opened to allow water to arrive water tap 20 from flowing through therebetween, central opening 138 will reexpand like this.We preferably are supplied to water stream channel 60 to the water that discharges through valve 90.In addition, soap will be drawn into pump 74 from container 68.

Banding valve pump 142, such as among Fig. 8 the best show brightly, be similar to pump 74, its difference is to be provided with inserted link linkage 144 and 146 respectively at the entrance and exit place of pump 142.What be different from pump 74 in addition is, the pipeline 148 that extends to soap container 68 is extend past pump 142 not.Similarly, the pipeline 150 that is connected on the connector 146 extends to water tap 20.Like this, the central opening 138 of utricule 136 itself forms a soap pipeline.Certainly, all being provided with flap valve in the front and back of pump 142 flows to pump 142 and then flows to water tap 20 to guarantee soap.

Shown in Figure 8 is flap valve 152, is preferably a ball check valve, and it is that the pipeline 92 that extends to water tap supplies water.Usually solenoid 154 operations that are in closed condition are positioned at the control valve 156 of pipeline 50 discharge ends.Cable 158 transmission operating powers and control signal are so that solenoid valve 154 operations.Flap valve 152 stops water by pipeline 92 flow valves 156, and its size is done so that the water that flows out suddenly from pipeline 150 is transferred to the pump 142 fully.Flap valve 152 just serves as a hole like this, allows water to flow when solenoid 154 is closed valve 156.

Shown in Figure 6 is the rotary peristaltic pump of an electricity operation, and this pump also can be used for cleaning material 126 is drawn into water tap 20.Pump 160 has a dismountable lid 162, and it repeatedly is pressed on

support

164 and 166, and central axis 168 is by unshowned motor-driven.Axle 168 drives folder and refers to 170 along its peripolesis, so that match with the elastic pipeline 172 of supply soap.The soap pipeline 174 supply soap of pipeline 172 for extending to water tap 20.

The rotation of axle 168 makes folder refer to that 170 cooperate with pipeline 172 selectively, thereby makes part folder refer to that 170 is oppressed to lid 162.This motion is a tumbling-type, when rotation continues to carry out, tends to soap is pressed to soap pipeline 174.The backwards rotation of axle 168 will cause soap to be sucked into from pipeline 174 among the pipeline 172, so just the possibility of soap from pipeline 174 water clocks to kitchen sink 14 be dropped to minimum.

Lid 162 can be removed from its position that overlaps with respect to axle 168 and support 164 and 166, thereby soap pipeline 172 is changed when can convenient soap in container 68 having used up.This is that a minimum effective method is reduced in the pollution of interface.Should be appreciated that soap container and pipeline can be integrated elements, thereby be convenient to change.

Mention that as top button pressing selector switch 22 is installed on the upper surface 16 near the cupboard 10 of water tap 20.Above-mentioned selector switch is an on-off switch.We have found that sometimes the user only needs water, for example be used to drink.In this case, selector switch 22 can allow effectively only from water tap 20 dispensing water.As mentioned above, coil paper is owing to the effect of second sensor 34 is come out from applicator 32 dispensings at any time.When pressing button 22 was in the position of " only supplying water ", display 38 and inoperation because display 38 is operated by controller 176, and only just increased counting when soap is discharged.

The electricity control element of the control cleaning station W1 that is useful on all is installed among the

electronic controller

176, and 176 of electronic controllers are positioned within the cupboard 10.Controller 176 can be a hardware, also can be a programmable logic controller.Controller 176 promising displays 38, solenoid operated

valve

52,54,84,90 and 78 receive the function of the various required signals of telecommunication.Preferably, central controller 176 should be connected with a main frame.

That shown in Figure 9 is cleaning station W2.Cleaning station W2 should be suitable for using with the kitchen sink of conventional design.One first infrared sensor 180, preferably active, be installed on the surface 182 of kitchen sink 178 and be used to determine that user's hand appears under the water tap 20.The water tap 20 of the water tap of cleaning station W2 and cleaning station W1 is identical, so needn't further discuss it again.

On surface 182 second sensor 184 is installed also simultaneously, it also is active.Sensor 184 is upwards surveyed, and sensor 180 is then surveyed to horizontal direction.Like this, the detection eye of sensor 180 just is considered to be in to be operated on the horizontal plane, and the detection eye of sensor 184 is then operated on a vertical plane, and the direction that extend on this plane and the plane of sensor 180 roughly are crosscuts mutually.This relation has been avoided because the inaccurate location of user's hand is caused obscuring of controller 176.

Cleaning station W2 has manual

feed water valve

186 and 188, and the water of its pressurized is supplied to cleaning station W2.Usually solenoid 190 operation control valves 192 that are in closed condition are so that water flows to T-type connector 194 by pipeline 196 selectively.Similarly, be in solenoid 198 operation control valves 200 of closed condition usually so that water flows to T-type connector 194 by pipeline 202.Pipeline 204 extends to control valve 206 from manual valve 188.Valve 206 is to be operated by the solenoid 208 that is in closed condition usually.Flap valve 210 is that pipeline 212 supplies water, and pipeline 212 is communicated with pipeline 202 by T-type connector.Pump 213 is identical with the pump 218 among Fig. 8, and it has a soap supply line 215 that extends out from soap container 216.Soap pipeline 218 extends to pipeline 80 from the outlet of pump 142.Generally,

flap valve

217 and 219 can be a ball check valve, is installed between container 216 and the water tap 20 so that the suction of control soap.

Control cabinet 220 is installed on gutter 222 vertical support frame afterwards.Electric wire extends to each parts of equipment from control cabinet 220, and preferably electric wire should have can alleviate stress plug-in package 224 to reduce the aging of cable as far as possible.

We have found that sensor 184 is more preferred than pressing button 22, particularly under hospital environment.Sensor 184 is upwards surveyed, thus just needn't contact by the user, thus make the possibility that causes infecting because contacting the left infective agent of contact more early drop to minimum.For control cabinet 220 can be changed " washing one's hands " pattern of cleaning station W2 and " only supplying water " pattern, the user only needs handle to be placed on to reach the sufficiently long time on the sensor 184.We have found that about 3 seconds sensitive time is promptly enough, so just avoided when hand promptly passes through the scanning area of sensor 184, unexpectedly triggering sensor 184.Equally, when sensor 184 was set in cleaning model to cleaning station, preferably needing could actuation sensor 180 through the induction of selected time.So just can further guarantee to operate unintentionally unlikely generation.In other words, at first make cleaning station be in " washing one's hands " pattern, and then handle is put under the water tap.

Shown in Figure 12 is a conceptual scheme, is connected on central computer or the main frame by this conceptual scheme cleaning station W1 and W2.Control device, corresponding to the controller 176 of cleaning station W1, operation display 38 and soap weight-measuring device 70.Simultaneously, control device is supplied to central computer to relevant operation information, and if necessary, central computer promptly can be notified to be needed the corresponding cleaning station is safeguarded.Might need display 38 is linked to each other with central computer by controller 176 with soap weight-measuring device 70, this just allows central computer to inquire that periodically display and soap weight detector are so that the use of monitoring cleaning station.

Figure 10 and shown in Figure 11 be the circuit connection diagram that makes up cleaning station W1 and W2.The skilled person of this technology should be understood the circuit connection diagram of Figure 10 and 11 and can be assembled by hardware, perhaps also can for example realize with a programmable controller by software control.

Framework " normally " indication is all normal residing state of cleaning station W1 and W2, only discharges water under this pattern.Under normal mode, to relay or output X1 power supply.

Usually the contact-making switch 226 that is in the timer T6 of opening must be closed so that electric current can be supplied to timer T1 by the contact 228 that relay R 4 is in closed condition usually.So just provide one to reset function, when making system enter auto state with box lunch one potential user, the user must finish some actions in the visual field of sensor 18 in the time of selecting that timer T1 sets.Do not take place if whatever in one 40 seconds period, then timer T1 timing stops, thereby control system is reset to normal mode.Only under automatic mode, just need reset.

Usually the contact 230 that is in the relay R 1 of opening is closed at timer T1 timer, thereby provides one to hold and stay the loop because the contact 232 of timer T1 is in normal closed condition, and the contact 234 of relay R 4 also is like this.Contact 230 is positioned at the inside of relay R 1, and causes applying a successive control signal, because when the set time has been consumed, timer T1 will only provide a control signal.

Usually the contact 236 that is in the relay X2 of opening causes timer T6 to obtain operation.Timer T6 is used for determining whether handle is placed on the one sufficiently long period that reaches on the sensor to the user.We have found that about 3 seconds time has been enough to promptly determine that the user wishes cleaning station is transformed into automatic mode.

Usually be in the contact 238 of the relay R 1 of opening, the contact 240 of relay X1, the operation of the contact 242 control timer T2 of timer T0.Timer T0 provides the time-out in one 1 second, and this is that to allow the user have the time enough handle to be put under the water tap 20 necessary.In case timer T0 timing finishes, promptly by operated

valve

52 and 54, perhaps

valve

192 and 198 discharged water water tap 20 0.1 second to timer T2, used those valves to depend on employed cleaning station.The above-mentioned water of emitting foot is got wet in handle.

Usually the contact 244 that is in opening is positioned at the inside of relay T2.Contact 244 extends to the contact 246 that is in opening usually, and contact 246 is positioned at the inside of relay X1.The contact 248 that normally is in closed condition is linked in contact 246, and contact 248 is positioned at the inside of timer T3.The contact 250 that normally is in closed condition is received in contact 248, and contact 250 is positioned at the inside of the relay Y2 that is used to operate.Relay Y2 is pump 160 power supplies, perhaps makes

pump solenoid

84 or 206 operations.

Usually the contact 254 that is in opening is positioned at the inside of relay Y2 and links on the timer T3.Timer T3 preferably sets about 4 seconds time so that pump can be supplied the soap of capacity.If use banding valve pump 74 or 142, then the time of She Dinging needn't reach 4 seconds.

Usually the contact 256 that is in opening is positioned at the inside of relay Y2.Similarly, the contact 258 that is in opening usually is positioned at the inside of relay R 2.The contact 260 that is in closed condition is usually received in contact 256 and 258, and contact 260 is positioned at the inside of timer T4.Contact 260 is received on the relay R 2 and is provided one to hold and stay the loop during timer T3 timing.

Usually the contact 262 that is in opening is positioned at the inside of relay R 2 and receives on the contact 264 that is in closed condition usually, and contact 264 is positioned at the inside of relay Y2.Receive on timer T4 and time-delay relay (hold-in) R3 contact 264.We have found that timer T4 should set the time in about 15 seconds, it is even that this will make the user have the sufficient time that soap is rubbed with the hands after the soap dispensing.At this loitering phase, do not permit water to flow to water tap 20.Usually the contact 260 that is in opening is positioned at the inside of relay T4, and receives on the timer T5.Similarly, the contact 270 that is in closed condition usually is positioned at the inside of timer T5.Timer T5 actuate and delay circuit that relay R 4 is provided makes water discharge from water tap 20 to come out to reach 5 seconds.We have found that

solenoid valve

52 and 54, perhaps 192 and 198, the time of moving for 5 seconds can be wiped even soap to the user on hand and be cleaned.

Usually the contact 272 that is in opening is positioned at the inside of relay R 4, and receives on the relay Y1, relay Y1 control

water solenoid valve

52 and 54, perhaps 192 and 198.Similarly, the contact 274 that is in closed condition usually is positioned at the inside of relay R 1, and receives on the contact 276 of the relay X1 that is in opening usually.Receive on the contact 278 of the relay R 3 that is in closed condition usually contact 276.Usually receive on the contact 282 of the timer T0 that is in opening usually the contact 280 that is in the timer T2 of closed condition.Receive on the contact 284 of the relay R 1 that is in opening usually contact 282.

As mentioned above, timer T0 is set for we so that the user has the time enough handle to be put under the water tap 20.Timer T0 is controlled by the contact 286 of the relay R 1 that is in opening usually, and it also is subjected to the control of the contact 290 of the contact 288 of relay X1 and timer T0.

Usually the contact 292 that is in the relay R 62 of opening makes the running of relay Y0.The operation of the motor 120 of relay Y0 control coil paper applicator 32.This just guarantees to discharge at any time no matter cleaning station is being carried out that a kind of other function paper handkerchief.

Usually be in the contact 294 operational relay R60 of the relay X1 of opening, with guarantee when be in normal mode and user handle after sensor 34 is removed, discharge the paper.We have found that sometimes some article or other things actuation sensor 34 mistakenly.If allow the motor operation after handle has moved apart sensor 34 " people " that detect, above-mentioned situation can be avoided.Otherwise,, then do not discharge paper handkerchief if hand is not removed.

Usually receive on the contact 298 of the relay R 62 that is in closed condition usually the contact 296 that is in the relay R 60 of opening.Similarly, receive on the contact 298 contact 300 that is in the relay R 61 of opening usually.

Usually receive on the contact 304 of the relay R 60 that is in closure state usually the contact 302 that is in the relay R 61 of opening.Receive on the contact 306 of the relay R 4 that is in closure state usually contact 304.Receive on relay R 62 and the timer T7 contact 306.Similarly, receive on the contact 310 of the timer T7 that is in closed condition usually the contact 308 that is in the relay R 62 of opening usually.Receive on the contact 306 contact 310.This has just guaranteed that applicator 32 can discharge the set paper handkerchief of a segment length, because the time of motor 120 operations is set.

The operation of W1 and W2 embodiment

Because

use sensor

18 and 180 and

selector switch

22 and 184, so the operation of cleaning station W1 and W2 is automation fully.The user only need walk close to cleaning station, does desired action then, no matter the user need wash one's hands, water intaking perhaps only needs paper handkerchief, all is automation.

Cleaning station W1 and W2 are in " water dispensing " pattern usually, this means to have only as the user water is placed under the water tap 20, and when being positioned at the detecting area of

sensor

18 or 180, the user just can make water come out from water tap 20 dispensings.Under above situation, how long water or other article as water pitcher, are placed under the water tap, and how long contact 274,276 and 278 just guarantees the water dispensing.If the user removes hand, then contact 280,282 and 284 and timer make water after hand is removed, continue the dispensing 1 second.We find that this delay function is desirable because sometimes the user by mistake handle move apart the detecting area of sensor 18 or 180.Like this, the time-delay stage stops

control valve

52 and 54, perhaps 192 and 198 quick conversion.Need not waste a lot of water like this and can reduce to minimum to the loss of system.

If the user needs in the applicator 32 dispensing paper, then he (she) only needs be placed on a hand before the sensor 34 and this hand is moved.This has just started motor 120, and motor will move the time by timer T7 setting.The minimizing of the paper length that causes because of paper roll 122 diameter variation is very little.

If the user need wash one's hands with cleaning station, then can finish at an easy rate, only need this moment subdue pushing button 22, perhaps handle is placed on and reaches a required time on the sensor 184 and get final product.In case the user is put in the required time that reaches on the sensor 184 to hand, then controller 176 is arranged at automatic mode to cleaning station or the pattern of washing one's hands.

In case be in automatic mode, then the user needs handle to be placed under the water tap 20 and is in this section of detecting area period of

sensor

18 or 180, and the above-mentioned time is set by timer T1.So just having determined that the user is provided with leaves cleaning station after being in automatic mode.If he (she) has left, then in a single day timer T1 timing stops, and promptly system is reseted in normal mode.

After having determined that the user is placed on hand within the detecting area of

sensor

18 or 180,, perhaps 192 and 198 just bring into operation and get wet with the water handle of supply capacity by the

valve

52 and 54 of nut ring manipulation.Most of cleaning agent is water miscible, so for the process of washing one's hands normally, to get wet be desirable to handle before coating liquid soap.This does not need too many water, as long as can get wet just enough by handle.

In case hand is got wet, then control the 176 any one runnings of passing through pump 74,142 or 160 soap is aspirated up.We can be by regulating pump 74 or 142 the thickness of pipe of central opening 136, perhaps regulate the suction time of peristaltic pump 160, control the aspiration of soap.The skilled person of this technology should be appreciated that, amount of soap is not enough or excessive all be not conform with demand.So it is the suitable method of guaranteeing that capacity soap is discharged that draw volume is regulated, above-mentioned amount of soap is according to concrete purposes and fixed.

In case soap is sucked, within a period of time, do not allow water from water tap 20, to flow out, the above-mentioned time is set by timer T4.We have found that be enough to handle 15 seconds for common user and wiped evenly, in case that soap has been wiped is even, i.e. timer T4 timing finishes, then timer T5 makes 5 seconds time of water dispensing, and foot soap rinsing on handle is clean for this.

The

solenoid valve

52 and 54 that carries out in order to discharge washings, perhaps 192 and 198 operation is energized relay R 6, thereby actuates timer T7, and paper handkerchief is promptly discharged out and is reached a seclected time like this.The user can dry with handle tearing it down from applicator 32 in the paper.Like this, the user does not need to contact any one position of cleaning station W1 or W2 after hand rinsing is clean.Like this, the propagation of infection is reduced to minimum level, because cleaning station W1 and W2 have guaranteed the suitable cleaning of hand.

Cleaning station W3 shown in Figure 13 and the cleaning station W1 shown in Fig. 1 are similar.Because its similitude, so similarly number is indicated similar elements.The main distinction of cleaning station W3 and cleaning station W1 is that W3 has a soap jet pipe independently, its by one independently sensor triggered, and W3 also has the button of pushing so that can make water time-delay dispensing.In addition, also be provided with an alphameric display so that provide information for the user.

Such as Figure 13 the best show brightly, soap jet pipe 312 is close to water tap 20 and is secured on the top 16.Jet pipe 312 has a nozzle 314, and nozzle 314 is put on kitchen sink 14, soap, and bactericide, or suitable antimicrobial reagent can discharge out by nozzle.Soap can described from here any pump, and perhaps other any pumps are supplied to nozzle 314.Preferred pump is the peristaltic pump of type as shown in Figure 6.

Within jet pipe 312, be provided with an active infra-red sensing system to actuate pump so that soap is discharged.Lens 316 and 318 are set up respectively in order to transmit the signal that infrared signal and reception are reflected.Thereby when having only the user to be placed on operative position shake-up sensor-based system by handle, soap is just discharged, and above-mentioned operative position shows that by reflection of light the user need discharge soap.So as long as user's one straight grip is placed under the water tap 20, water is dispensing continuously just, and before the sensor of jet pipe 312 was excited, cleaning station W3 did not enter " washing one's hands " pattern.

Sometimes the user needs water from water tap 20 time-delay dispensing so that for example water pitcher or wash pond 14 topped up with water clearly.Yet in this case, the user does not wish or can't handle remains on suitable position with respect to sensor 18 to keep current.Push button 320 to keep current so be provided with, pushing the optional position of button is to be installed on the paper handkerchief applicator 32.Pushing button can be any suitable press button, locks as keeping before pushing again, and perhaps the time is controlled, or the like, like this as long as button 320 is in the shake-up state, water is sustainable from water tap 20 outflows.

The potential user that the place is set of cleaning station disclosed herein has different backgrounds usually, and suffered training is also different.Should make these people correctly use cleaning station so that the greatest benefit of performance cleaning station.For this reason, be provided with an alphanumeric display 322 so that provide for example instruction of information for the user.Display 322 can be arranged within the paper handkerchief applicator 32, perhaps can be positioned other positions.The user can observe the alphanumeric display at any time like this, and the alphanumeric display is except providing indicative information, also can provide other information, as showing the time of having used, next step time, or the like, this can help to make the user not leave cleaning station W3 before finishing the cycle of washing one's hands.In addition, display 322 also can be hospital information is provided, for example, about using total degree, the total degree of suitable use, or otherwise information so as to make hospital can determine cleaning station W3 by correct use with and frequency of utilization.

Shown in Figure 14 is the control system of cleaning station W3.As shown in FIG., a controller, it can be a microprocessor or programmable logic controller, and the water sensor of coming from 18 is arranged, soap sensor 316,318, and the incoming line of paper handkerchief applicator sensor 34.In this embodiment, preferred paper handkerchief applicator sensor is an active sensor.The outlet line of controller is received valve, as valve 52 and/or 54, and pump, as peristaltic pump 160, and paper handkerchief applicator 32.

A common user can go to cleaning station W3 and handle is put under the water tap 20, so just allows sensor 18 to detect user's existence.Consequently controller makes that the valve of linking on the water tap 20 is operated, and makes water flow to water tap.As long as sensor 18 detects user's existence always, water will continue dispensing.Perhaps, as long as press button 320 is operated, water just continues dispensing.

If the user need wash one's hands, then should be earlier with the wet hand of hand.This can be placed under the water tap 20 and be within the opereating specification of sensor 18 and be achieved by handle.Then the user executes at least one hand under the jet pipe 314 and is positioned within the opereating specification of sensor, and the sensor scioptics 316 and 318 act on.The soap sensor of actuating in this way carries a signal to give controller, and this information notification controller should normally residing from it " water dispensing " pattern be transformed into second or " washing one's hands " pattern.This order thereby be different from aforesaid order, in aforementioned order, cleaning station at first is placed in " washing one's hands " pattern, and then discharges the water of a controlled quentity controlled variable.So cleaning station W3 is the comparison close friend to the user.Then discharge soap, the dispensing of soap is converted to controller " washing one's hands " pattern.

In case be in " washing one's hands " pattern, then the control of water and soap is promptly based on the order of above-mentioned programmed in advance.Like this, pump is actuated and discharges soap by nozzle 314, and this moment, water no longer flowed out from water tap 20.In case it is even that hand has time enough to rub with the hands, then discharges water once more by water tap 20.In case discharged the water of capacity, then penstock is closed, discharge paper handkerchiefs 36 by the effect of motor from applicator 36 then.

Alphanumeric display device 322, it can be the CRT screen, LCD or the like is also actuated by controller so that provide information for the user.Like this, for example, display can initially be set up and show that to the user cleaning station W3 is in " only supplying water " pattern.Make the water dispensing in case be converted into the controller of " washing one's hands " pattern, then display can be notified the user next procedure apart from carrying out last time of next procedure and similar information.

Some, alphanumeric display device also can provide the information of other types, so that the user does not leave cleaning station W3 before finishing a cycle of washing one's hands except above-mentioned.The people is perhaps not very willing one by one obtains information from cleaning station W3, and perhaps he (she) can be impatient in the process of order of washing one's hands.Like this, display 322 for example can provide the information about the frequency of washing one's hands, about the general objects information of the importance of washing one's hands, perhaps more about the general information of recent event etc.Its objective is and make the user not leave cleaning station W3 so that the order of washing one's hands is finished satisfactorily.

Though being described as, the present invention has a decision design, should be appreciated that the present invention can further be used, revise and/or adjust, as known in the technology of institute of the present invention subordinate, perhaps common use general, as be applied to the above-described central characteristics, and these use, and revise and/or adapt within the restriction of the claim that all belongs to scope of the present invention and augment.
