Abstract

The present invention provided an automatic ice-making device which prevents entry of bacteria in the air and odor of food, suppresses noise evolved from the device, makes the quantity of water fed uniform, and enables easily checking the amount of water in a feedwater tank by means of a simple structure. To feed an ice-making dish with water, a driving mechanism is made to elevate an interlocking valve so that a fixed amount of water, which has collected in a fixed-quantity chamber in a feedwater tank, is discharged into a receiving pan and a feedwater pump thereafter forces this water up through a discharge hose to the ice-making dish.

Description

Automatic ice-making plant and be used for the tank of this device

The present invention relates to a kind of tank that can the automatic ice-making plant of ice making water is provided and be used for this device to ice-making disc.

Japanese patent application publication No. 3-137473 discloses the automatic ice-making plant of the above-mentioned type in the past, and its structure as shown in figure 42.

With reference to Figure 42, water tank 300 comprises a measuring vessel 301, a groove 302 and a cistern 303.Cistern 303 has the supply flume 308 of a band valve 304 and valve gap 305.Measuring vessel 301 comprises a motor 307 and a supply-water pump that has feed pipe 309 with impeller blade 306.

Because said structure, the water in the supply flume 308 can be flowed through valve 304 and is stored in the water tank 300, and water can be introduced in the measuring vessel 301 through valve gap 305 then.In water supply period, water is by being pumped out in the measuring vessel 301.At this moment, allow to flow through valve gap 305 owing to supply with the water of measuring vessel 301, so can reduce the flow of unit interval, therefore, the water in the measuring vessel 301 is with predetermined amount the supply system ice pan.

Though the water in the above-mentioned automatic ice-making plant can offer ice-making disc, and and whether be in vertical position irrelevantly between ice-making disc and the water supply installation, problem is because the structure of supply-water pump etc. makes totle drilling cost to reduce.Another shortcoming is to produce excessive noise.

That is to say that existing problem is that the motor 307 of supply-water pump between delivery period can produce rotational noise.What is worse, because motor 307 rotations are inhomogeneous, the error that occurs when refrigerator inclination that causes when laying refrigerator and build-up member etc. all can make measuring vessel 301 tilt.This inclination has changed water level, and the water yield that supplies water to ice-making disc is not conformed to the rules.

Structure traditional ice maker has as shown in figure 43 overcome above-mentioned shortcoming, and this device is disclosed in Japan Patent and discloses in 3-221769 number.

This automatic ice-making plant has following structure: ice-making disc 312 is arranged in the ice-making compartment 310, and water supply unit 313 is arranged in the refrigerating chamber 311, and like this, the water in the supply flume 314 can offer ice-making disc 312 from water supply unit 313.

Specifically the ice-making disc 312 in the ice-making compartment 310 is placed on the position that is lower than the water supply unit 313 in the refrigerating chamber 311, and ice-making disc 312 links to each other with water supply unit 313 by feed pipe 322.

Water supply unit 313 comprises a water container 315 and a cistern 323.In addition, supply flume 314 is arranged on the top of cistern 323.

A water inlet 317 is arranged at the top of water container 315, and water inlet 317 makes between cistern 323 and the water storage part 316 and is communicated with.In addition, a delivery port 318 is arranged at the bottom of water container 315, and this delivery port 318 makes between water storage part 316 and the feed pipe 322 and is communicated with.Water inlet 317 and delivery port 318 can be opened or close to utilization by an inlet valve 320 and an outlet valve 321 of solenoid 319 controls.

That is to say that solenoid 319 is controlled inlet valve 320 and outlet valve 321 by this way: delivery port 318 is closed when water inlet 317 is opened, and delivery port 318 is opened when water inlet 317 is closed.

Because said structure, the water of discharging from supply flume 314 temporarily is stored in the cistern 323, and subsequently, water can be introduced into water storage part 316 by water inlet 317.Outlet valve 321 cuts out owing to inlet valve 310 unlatchings at this moment, is stored in the water storage part 316 so introduce the water of water storage part 316, so just makes in the water storage part 316 to be full of water.When water was defeated by ice-making disc 312, electric coil 319 was energized, and outlet valve 321 is opened, and inlet valve 320 cuts out.Consequently have only the water in the water storage part 316 to be introduced in the ice-making disc 312, so just the water of scheduled volume can be offered ice-making disc 312 by feed pipe 322.

The automatic ice-making plant of the above-mentioned type comprises all that generally the tank that is used to detect the water supply checkout gear of whether finishing to tank water supply situation and ice making and is used to detect the situation that is provided with of supply flume is provided with checkout gear.

Figure 44 is the sectional drawing of refrigerator, and this refrigerator comprises that one has and is disclosed in the water supply checkout gear among the Japanese Utility Model publication number 2-128069 and is disclosed in the automatic ice-making plant that tank in open 1-136869 number of the Japanese Utility Model is provided with checkout gear.

With reference to Figure 44, Reference numeral 330 is represented refrigerating chamber.Supply flume 331 is arranged in this refrigerating chamber 330.Supply flume 331 is connected on the centrifugal supply-water pump 333 by a water storage dish 332.The feed pipe 334 that is connected on the ice-making disc 336 in the refrigerating chamber 335 is fixed on the supply-water pump 333.

Just, can utilize supply-water pump 333 that water is transported to ice-making disc 336 by feed pipe 334 subsequently because the structure that constitutes like this can temporarily be stored in the water storage dish 332 water in the supply flume 331.

Figure 45 is the perspective view that expression is arranged on the water supply checkout gear in the above-mentioned automatic ice-making plant.Water supply checkout gear 340 comprises that one is fixed on and is arranged in the refrigerator or the outer indicator lamp 342 of refrigerator near the temperature sensor 341 of ice-making disc 336 certain position in the refrigerating chamber 335 and one.

Temperature sensor 341 detects to ice-making disc temperature rise in the refrigerating chamber 335 between 336 delivery periods, and whether the water supply to ice-making disc 336 for confirmation is normal.

Specifically, when in ice-making disc 336 water supply operating process as not detecting temperature rise, then judge in the supply flume 331 anhydrously, thereby indicator lamp 342 is bright, thereby urges the user to supply water in supply flume 331.In supply flume 331 again behind the water-filling, indicator lamp 342 extinguishes the user.

Figure 46 is the schematic diagram that the explanation tank is provided with checkout gear.

With reference to Figure 46, on behalf of tank, Reference numeral 350 checkout gear is set.Tank is provided with checkout gear 350 and comprises that a band exposes the bar 355 that the switch 352 of button 351 and can rotate around pivot 353, and spring 354 hauls bar 355 towards the direction of button 351.

Because said structure, if do not place supply flume 331, then spring 354 makes bar 355 rotate along the direction of arrow indication, and like this, the right-hand member of bar 355 is pushed down button 351, and switch 352 is connected.Therefore, can detect and do not place supply flume 331.Otherwise if supply flume 331 has been placed, then bar 355 rotates along the contrary spring 345 of the rightabout of arrow indication.Therefore, the right-hand member of bar 355 and button 351 break away from, and switch 352 is disconnected.So can detect supply flume has been put appropriate.

Yet, be disclosed in open 3-221769 number of the Japan Patent and the automatic ice-making plant that constitutes in a manner described can make the water that is stored in the water container 323 contact with air.In these cases, be suspended in airborne bacterium and invade in the water of cistern 323, therefore have water to be clamminess or rancid danger.

In addition, the feed water inlet of supply flume 314 is too little, can't clean supply flume 314.So, not being used for a long time if be stored in the water of 314 li of supply flumes, solenoid 319 is energized then, and with antihygienic water the supply system ice pan 312 in the supply flume 314, this is extremely harmful.

What is worse, the water in the cistern can be caught the smell of food in the refrigerating chamber 311, and this can produce the problem of odour nuisance with regard to causing the ice of making.

Comprise being disclosed in the water supply checkout gear in open 2-128069 number of the Japanese Utility Model and being disclosed in the automatic ice-making plant that tank in open 1-136869 number of the Japanese Utility Model is provided with checkout gear and arrange in the following manner: as long as relay supply flume 331 appropriate, no matter whether the water supply in supply flume 331 is finished, the indicator lamp 342 of water supply checkout gear 340 all can extinguish.Therefore, if supply flume 331 is just reapposed when not adding water mistakenly, indicator lamp 342 also is in the nonconforming state that extinguishes.Therefore, the user can't judge whether added water from icy machine outside, and can make the user obtain adding to supply flume 331 the erroneous picture of water.

Because it is very complicated aspect frame for movement that this tank is provided with checkout gear 350, so the cost of automatic ice-making plant can't reduce.Another problem is, owing to freezing that operation can't be carried out.

Use the above-mentioned automatic ice-making plant of centrifugal supply-water pump 333 can make the water of staying in the feed pipe 334 when supply-water pump 333 quits work, turn back to storage in the water storage dish 332.Like this, the president goes out algae and grows mould in the water of water storage dish 332, therefore must regularly clean water storage dish 332.This just produces the inconvenient problem of maintenance.

In order to overcome above-mentioned shortcoming, the purpose of this invention is to provide a kind of automatic ice-making plant and the supply flume that is used for this automatic ice-making plant, this device can prevent airborne bacterium intrusion, prevent that sealing is spoiled and prevent to produce noise, its output is even, and whether available simple structural confirmation supply flume has been put appropriate.

To achieve these goals, according to a part of content of the present invention, this automatic ice-making plant comprises a supply flume, a drive unit and a supply-water pump, wherein supply flume comprises a demand chamber and a valve gear, and when water flowed into demand chamber, valve gear cut out outlet valve, when water flowed out demand chamber, valve gear was opened inlet valve; Drive unit is used for the control valve device, so that water offers the water storage dish from demand chamber; Supply-water pump is used for the water of water storage dish is taken out to ice-making disc.

Because said structure, the outlet valve of valve gear cuts out when water flows into demand chamber, and inlet valve cuts out when water flows out demand chamber.Supply with the water storage dish from the water that demand chamber is discharged, and utilize supply-water pump the water the supply system ice pan in the water storage dish.Therefore, the water in the demand chamber always can offer ice-making disc by predetermined amount.Because the time that water contacts with outside air is not long, therefore can prevent in the airborne bacterium encroached water, like this, just water is clamminess and fouls.In addition, can clean and keep in repair supply flume easily.

In a kind of form of the present invention, automatic ice-making plant has an open/close control device of control draining valve, and the ON/OFF of this draining valve is used for the ON/OFF drainage channel again.When control device was opened draining valve, the water in the water storage dish entered drainage channel.Therefore, even water has been left in the water storage dish, water also can be discharged fully, so the water storage dish can not be clamminess and foul yet.

The preferred embodiments of the present invention are described below with reference to accompanying drawings.

Fig. 1 is the simple schematic diagram of refrigerator that is equipped with according to the automatic ice-making plant of first embodiment of the invention; Fig. 2 is the generalized section of expression according to the automatic ice-making plant of this embodiment; Fig. 3 is the cutaway view of this embodiment essential part of expression.

With reference to Fig. 1, refrigerator 1 has a refrigerating chamber 2 and a refrigerating chamber 3 that is arranged on this refrigerating chamber 2.Water supply cell wall angle 4 is positioned at the top of refrigerating chamber 2.And ice making wall angle 5 is positioned at the below of refrigerating chamber 3.Automatic ice-making plant is located in each water supply cell wall angle 4 and the ice making wall angle 5.

As shown in Figure 2, supply flume 10 is fixed in the water supply cell wall angle 4, has the bottom that the larger-diameter fastening port 11 that hand is put in is located at supply flume 10.In addition, demand chamber 20 is fixed on the fastening port 11.

Demand chamber 20 is made up of valve gap 21, middleboxes 23 and last box 25, and wherein valve gap 21 is screwed on the fastening port 11 by screw thread, and the middle body of this valve gap has an outlet 22; One inlet 24 is arranged at the top in the middleboxes 23; Last box 25 is equipped with activated carbon 26.

The interlocked valve 27 that is used for ON/OFF delivery port 22 and water inlet 24 is fixed on the delivery port 22 of valve gap 21.

Interlocked valve 27 has the outlet valve 28 and the inlet valve 29 that is used to close water inlet 24 that are used to close water outlet 22, and this interlocked valve 27 is being pushed away downwards by spring 30.That is to say that if there is not masterpiece to use on the interlocked valve 27, then interlocked valve 27 moves downward under the effect of spring 30, water inlet 24 is opened, delivery port 22 is closed.

Middleboxes 23 is fixed on the valve gap 21 by screw thread or counterpart, and a passage 23a is arranged at the top of middleboxes 23.Last box 25 is fixed to the upper surface of middleboxes 23 by screw thread or counterpart, so just by activated carbon 26 water in the supply flume 10 is introduced demand chamber 20.Water storage dish 32 is located at the below of the fastening port 11 on the fixing middleboxes 23.One downward-sloping water channel 31 is arranged in the water storage dish 32, and the driving mechanism 40 that is used as drive unit is fixed on this water channel 31.

Driving mechanism 40 comprises a solenoid, utilizes its electromagnetic action that action bars 41 is moved both vertically, and this action bars 41 has the umbrella shape or the frustoconical functional unit 42 that are fixed to its front end.Therefore, the interlocked valve 27 of demand chamber 20 is upwards pushed away by frustoconical functional unit 42.

Setting operation parts 42 are in order to prevent that functional unit 42 is fabricated from a silicon from the fastener hole 31a of the water intrusion water channel 31 of delivery port 22.

When driving mechanism 40 turns round and when action bars 41 was moved upward, interlocked valve 27 was pushed to the top in a manner described, delivery port 22 is opened, and utilized inlet valve 29 that water inlet 24 is closed.

Water storage dish 32 has supply-water pump 45 as shown in Figure 2, and driving mechanism 40 is fixed on the water storage dish 32 in a manner described.Delivery hose 46 is connected to the top of supply-water pump 45.

Delivery hose 46 extends to the ice making wall angle 5 in the refrigerating chamber 3, and the front end of delivery hose 46 can reach a certain position of ice-making disc 47 tops in the ice making wall angle 5.

Supply-water pump 45 is not a centrifugal pump, but the integrated pump.

The ruuning situation of this embodiment will be described now.

If driving mechanism 40 does not turn round, the downward thrust of just having only spring 30 is to the interlocked valve 27 of demand chamber 20.Therefore, delivery port 22 is closed, and water inlet 24 is opened by outlet valve 28.

So under above-mentioned state, the water in the supply flume is introduced into box 25 through activated carbon 26, water can flow through water inlet 24 and enter middleboxes 23.

Utilize the effect of passage 23a, make water can introduce middleboxes 23 smoothly.Because outlet valve 28 is closed delivery port 22, so be full of water in the demand chamber 20 this moment.

When driving mechanism 40 operations, action bars 41 moves upward, the lower end that makes functional unit 42 contrary spring 30 thrust directions upwards push away interlocked valve 27.Like this, delivery port 22 is opened, and water inlet 24 is closed by water inlet valve 29.So the water in the middleboxes 23 can flow to water storage dish 32 through delivery port 22.Because the running of supply-water pump 45 can offer ice-making disc 47 by delivery hose 46 with the water in the water storage dish 32.

Because this moment, water inlet 24 was closed, the water yield of introducing water storage dish 32 equates with the volume of middleboxes 32 substantially.So, the water of identical with the volume of middleboxes 23 basically scheduled volume can be offered ice-making disc 47.

Because delivery port 22 is not used in the hole of ventilation, the time that water flows out can not immobilize, and the displacement of water storage dish 32 can not be constant.But, do not stay in the water storage dish 32 so do not have water because integrated pump 45 draws water immediately.That is to say,, also do not have water and stay in the water storage dish 32, therefore water is offered ice-making disc 47 with scheduled volume even the time that water flows out is irregular.

Fig. 4 is the schematic diagram that expression is used to control the control panel of driving mechanism 40 and supply-water pump 45 runnings.Fig. 5 is the time graph of running.

Control panel 50 is located in the refrigerator 1 and with driving mechanism 40 and links to each other with supply-water pump 45.Reference numeral 51 is represented the power supply of control panel 50.

As shown in Figure 5, when control panel 50 output water supply commencing signals, driving mechanism 40 startings are also turned round in the scope at the fixed time.Time control is adjustable at driving mechanism 40 starting back t1 and second supply-water pump 45 is turned round predetermined a period of time.

Time control also can be adjusted at driving mechanism 40 starting back t2 and second supply-water pump 45 is turned round predetermined a period of time.

Because the running of driving mechanism 40, the water of storing in the water storage dish 32 are extracted out by supply-water pump 45 and made water storage dish 32 become blank panel.

The gear-box (figure is omitted) that is used for ice-making disc 47 is rotated to take out ice is arranged in the refrigerating chamber 3.Gear-box detects the ice amount that is stored in the water storage tank, if storage ice amount does not meet the requirements, then control panel 50 sends above-mentioned water supply commencing signal.To the detection of ice amount is that door at refrigerating chamber 3 is opened or closed and constantly carries out.

As mentioned above, the automatic ice-making plant of present embodiment can prevent that sealing accumulates in the water storage dish 32, but water can offer ice-making disc 47 with predetermined amount.And the supply flume 10 that seals can prevent that sealing contacts with extraneous air.Therefore, airborne bacterium can not encroached water in, so just can avoid in water, occurring bacterium.

If the internal diameter that makes delivery hose 46 is less than predetermined value, then integrated pump 45 can all pump delivery hose 46 water interior and that be stored in feed pipe 31 and the water storage dish 32, so that supply water to ice-making disc 47.Therefore, can further prevent the generation of bacterium effectively.

In addition, can easily valve gap 21 be laid down and the heavy caliber fastening port 11 that hand stretches into supply flume 10 is come the inside part of supply flume 10 is cleaned.Because supply flume 10 and driving mechanism 40 are to constitute separately,, make maintenances such as cleaning and repairing be easy to carry out so can unload supply flume 10 at any time.

Because the functional unit 42 usefulness silicon materials of driving mechanism 40 are made, so can eliminate the impact noise of it and interlocked valve 27 basically.So just can avoid producing noise basically.

The another kind of arrangement of supply-water pump 45 will be described now.

Fig. 7 is the generalized section of first kind of modification of expression.

The modification of this layout is that supply-water pump 45 is arranged in the ice making wall angle 5 of refrigerating chamber 3, and goes into water tube hose 48 and extend downwardly into water storage dish 32 from supply-water pump 45.Going into the lower end of water tube hose 48 inserts in the groove 34 that forms in the water storage dish 32.

Preferably piston pump or the gear screw pump by the transporting water that rotatablely moves of the supply-water pump 45 of She Zhiing like this, but vavuum pump preferably.Because it does not need auxiliary equipment just water can be risen to satisfied height.

Fig. 8 is the generalized section of second kind of modification of expression.

The constituted mode of this modification is to be positioned at the position that is lower than water channel 31 and water storage dish 32 from supply-water pump 45, and delivery hose 46 is connected on the supply-water pump 45.

Fig. 9 is the generalized section of expression according to the automatic ice-making plant of second embodiment of the invention; Figure 10 is the schematic diagram that expression is applicable to the control panel of this embodiment; Figure 11 is the time graph of control panel.

The place that this embodiment is different from first embodiment is to be provided with a discharge structure, so that the water that will stay in the water storage dish 32 is drained.

The constituted mode of discharge structure as shown in Figure 9 is the below that drainage channel 35 is located at water storage dish 32, so that it is linked to each other with water storage dish 32.In addition, a scupper hose 36 is connected on the drainage channel 35.Again a draining valve 37 is fixed to the centre position of drainage channel 35.Because the situation in the ice-making disc 47 appears the water in the water storage dish 32 to be delivered in the position and the kind of supply-water pump 45 sometimes.This situation can cause water to be stayed in the water storage dish 32, and the danger of breed bacteria is arranged.

This valve of opening water discharge at any time 37 of present embodiment, enter scupper hose 36 and the structure that evaporates the water can be used to overcome above-mentioned shortcoming through drainage channel 35 with the water that will stay in the water storage dish 32.

The operation of draining valve 37, driving mechanism 40 and supply-water pump 45 is by control panel shown in Figure 10 52 controls.

That is to say, when control panel 52 by shown in Figure 11 when sending the water supply start signal, driving mechanism 40 is switched on and moves predetermined a period of time.Yet, supply-water pump 45 startings and predetermined a period of time of operation.

Because all the other structures, the method for operation is identical with first embodiment with effect, just repeats no more here.

To be expression according to the driving mechanism of third embodiment of the invention and supply-water pump in aggregates and be used for the perspective view of the black box of automatic ice-making plant for Figure 12; Figure 13 is the internal structure view of the black box of expression driving mechanism and supply-water pump; Figure 14 is that the A of Figure 13 is to view; Figure 15 is that the B of Figure 13 is to view.

The difference of this embodiment and first and second embodiment is to have used by driving mechanism 40 and supply-water pump 45 and is integral the driving mechanism that constitutes and the black box of supply-water pump.

With reference to Figure 12 and 13, the black box 60 of driving mechanism and supply-water pump has by driving mechanism 40 and supply-water pump 45 structures that constitute in aggregates.

Comprise a dual-axle motor 62 in the shell 61 of the black box 60 of driving mechanism and supply-water pump.As just leaving on the axle that the one-way clutch 63 that closes mechanism is fixed on dual-axle motor 62.In addition, supply-water pump 45 is located on the above-mentioned axle.The suction hose 64 that communicates with water storage dish 32 is connected on the end in the two ends of supply-water pump 45, and delivery hose 46 is connected on the other end.As being fixed on the one-way clutch 65 of the reverse clutch of one-way clutch 63 antiports on that remaining root axle of dual-axle motor 62.In addition, the front end of above-mentioned axle connects a reducing gear 66, and this reducing gear 66 is connected on the action bars 41 by gear 67.

Action bars 41 shown in Figure 14 and 15 has the elongated hole 41a and a plurality of rectangular opening 41b that are in extreme lower position, and action bars 41 hauls downwards by a spring 68 that is fixed on the shell 61.

Because this structure of the black box 60 of driving mechanism and supply-water pump, so when dual-axle motor 62 during with reverse rotation, one-way clutch 63 dallies.Again owing to being connected with one-way clutch 65, so the rotation of dual-axle motor 62 is passed to reducing gear 66.

Then, transmitting gear 67 makes it to cooperate with the rectangular opening 41b of action bars 41, makes the active force of the contrary springs 68 of action bars 41 and motion upward.When gear 67 further rotated and reach elongated hole 41a, gear 67 idle running made action bars 41 stop to move upward.When action bars 41 moved upward, functional unit 42 upwards pushed away interlocked valve 27.So the water in the demand chamber 20 is discharged into water storage dish 32, so that can be sent to supply-water pump 45 by suction hose 64.If power supply stops to dual-axle motor 62 power supplies under above-mentioned state, then reducing gear 66 idle running move downward action bars 41 under the effect of spring 68.Therefore, the delivery port 22 of valve gap 21 is closed by interlocked valve 27.

When dual-axle motor 62 is rotated in the forward, one-way clutch 65 idle running, and one-way clutch 63 engagements.Like this, supply-water pump 45 entrys into service make water be sucked out and deliver to delivery hose 46 through suction hose 64.

A modification of present embodiment will be described now.

Figure 16 is the generalized section of this modification of expression; Figure 17 is that the A of Figure 16 is to view.

The arrangement of this modification is: replace gear 67 with the cam 70 with helical spring 71.

Like this, when the b point of cam 70 in Figure 17 when the c point rotates, action bars 41 moves upward.If dual-axle motor 62 stalls or the outage situation under, helical spring 71 makes cam 70 rotate from the c point towards the b point.Therefore, action bars 41 moves downward.That is to say that when dual-axle motor 62 was pressed counter-rotating shown in Figure 180, the functional unit 42 that is located at action bars 41 front ends was pushed away and movement one predetermined angular up.When dual-axle motor 62 again during backward rotation, supply-water pump 45 entrys into service.

Because identical among remaining structure, mode of operation and effect and first and second embodiment is so just repeat no more here.

Figure 19 is the part enlarged drawing according to the water supply cell wall angle 4 that is added with a light emitting diode that automatic ice-making plant was suitable for of fourth embodiment of the invention.Figure 20 is the time response figure of delayed luminescence diode.

The present embodiment and first to the 3rd embodiment difference are, on the water supply cell wall angle 4 of refrigerator 1 water supply light emitting diode 80 and delayed luminescence diode 81 are housed.

Water supply light emitting diode 80 be widely used on the civilian automatic ice-making plant and be the light emitting diode of known technology.That is to say that if the water in the supply flume 10 is used up, the water supply light emitting diode is bright, urge the user is supplied water.When water has infeeded in the supply flume 10 and supply flume 10 has set, the light emitting diode 80 that then supplies water extinguishes.

After beginning a scheduled time (for example, a week) from setting supply flume 10, delayed luminescence diode 81 is luminous immediately, and makes driving mechanism 40 shut-down operations.When supply flume 10 was removed, 81 of this delayed luminescence diodes were not shinny.

Just, delayed luminescence diode 81 (as shown in figure 20) is provided with beginning t from supply flume 10 ₄Be switched on after hour, and when supply flume 10 is removed, extinguish.

Because this structure although the water in the supply flume 10 is easy to go bad, will stop to supply water in scheduled time supply flume 10 later.Therefore, though also can be relieved on the not ice making user psychology.

The relative position that water supply light emitting diode 80 and delayed luminescence diode 81 are installed is not limited to shown in Figure 19.

Figure 21 is the cutaway view according to the automatic ice-making plant of the 5th embodiment of the present invention.

Automatic ice-making plant according to this embodiment comprises the supply flume 90 that a valve cell 93 is housed, 100, one of a driving mechanism is placed on water storage dish 110 and supply-water pump 120 that the water in the water storage dish 110 is fed to ice-making disc 149 by

scupper hose

141 and 142 of supply flume 90 belows.

Supply flume 90 is fixed on the water supply cell wall angle, and fixing port 91 is positioned at the bottom of supply flume 90, and it has the major diameter part that a hand can stretch into.

Valve cell 93 is fixed on one and is installed on the cap 95 on the fixing port 91 by screw, and there is an outlet 94 in the centre of this cap.The top of the bar 97 in the through hole 96 that inserts cap 95 is fixed with a valve 98, and bar 97 by the effect of spring 99 downwards.That is to say that when bar 97 moves up, valve 98 is opened delivery port 94, the water in supply flume 90 can inject water storage dish 110.In addition, the lower surface at cap 95 stretches out the gauge line that draws water.

By screw, driving mechanism 100 is installed on the water storage dish 110, and action bars 101 is moved both vertically under the electromagnetic action of the solenoid that is placed on this place, with the cap 102 on the top by placing action bars 101 and the bar 97 of valve cell 93 is pushed away up.

More particularly, cap 102 is made by silicon rubber or similar material and is become a bag shape, and the inner surface of cap 102 is fixed on the top of action bars 101.Cap 102 is contained among the hole 110a of water storage dish 110 in the mode of liquid sealing, and its underpart installs to one as on the pad 103 of ventilation member simultaneously.

Therefore, when action bars 101 moved up, the upper surface of cap 102 was pulled on the bar 97.Because the upper surface of cap 102 pushes away up, make bar 97 overcome the power of spring 99 and move up, valve 98 is opened delivery port 94.When action bars 101 moved down, the upper surface of spring compressor 102 moved down, because the effect of the power of spring 99 moves down bar 97.Valve 98 has cut out delivery port 94 as a result.

Shown in Figure 22 and 23, pad 103 is cylindrical, and it has a hollow space 104, and action bars 101 is inserted into this hollow space, and pad 103 has a flange section 106, forms a plurality of grooves 105 that communicate with hollow space 104 on it.

As a result, when action bars 101 moved up and down, the air in the cap 102 can flow in the hollow space 104 by groove 105, or discharged from this part.Therefore, driving mechanism 100 can operate as normal so that the upper surface of cap 102 can move up or down exactly.

As shown in figure 21, a groove 111 is arranged at the bottom of being equipped with as the water storage dish 110 of the driving mechanism 100 of above-mentioned layout.The side surface of water storage dish 110 and basal surface tilt to groove 111, in addition, are placed with a removable granular membrane 112 in the inside of water storage dish 110.

The profile of filter 112 as shown in figure 24, it is shaped as the interior shape of the water storage dish 110 of putting into filter 112 parts.The core of filter 112 has a hole 112a, and formed hole 112a is used to admit cap 102.

By unloading cap 102 from action bars 101 and unloading filter 112, can remove the exotic that is attached on the filter 112 easily from take-up reel 110.

As shown in figure 21, the volume of water storage dish 110 should be defined as making when the water surface curve Z in the water storage dish 110 draws water the lower end of gauge line 95a, be full of water in the ice-making disc 149.

On the basal surface of the fixed form of going into water tube hose 119 for the groove 111 that its end 119a is pressed in water storage dish 110.End 119a should be mounted to and make the end form opening, and the basal surface of groove 111 can not be sealed above-mentioned opening.By making its end 119a favour the basal surface of groove 111, or by oblique section block end 119a or on the 119a of end, form a hole, the edge that makes its end separates with the basal surface of groove 111.

Water in the water storage dish 110 can be drawn onto the supply-water pump 120 from the bottom by soft suction hose 119 effectively as a result.

Supply-water pump 120 is placed in than on the also high position, the top of water storage dish 110, so that the water in the water storage dish is upwards inhaled.

As shown in figure 25, supply-water pump 120 comprises a motor 121, and a gear 122 is housed on its rotating shaft, and the

gear screw rod

124 and 125 that also rotates when gear 123 rotates with gear 122 engagements.When

gear screw rod

124 and 125 whens rotation, the water by soft suction hose 119 (as shown in figure 26) sucking-off is sent in the scupper hose 141.

The diameter D of soft suction hose 119 that is connected to supply-water pump 120 is very little, for example, is the vacuum that improves in the soft suction hose 119, and its diameter is about 6mm.The result can make the function of supply-water pump 120 be brought into play satisfactorily.

As shown in figure 26, on soft suction hose 119, can adorn a granular membrane 113.

Supply-water pump 120 can be contained in the water storage dish 110, and is admitted by shock-resistant member 130 shown in Figure 27 and 28.That is to say that the outlet 126 that links to each other with soft suction hose 119 is contained on two notch portion 131 of shock-resistant member 130, and make between the discharge outlet (not shown) of the outlet 132 that links to each other with delivery hose 141 and supply-water pump 120 and link to each other.In afore-mentioned, supply-water pump 120 recommended being placed in the shock-resistant member 130 are so that can be fallen by the shock absorbing that supply-water pump 120 is passed to driving mechanism 100.

As shown in figure 21, the drain hose 141 that links to each other with the discharge outlet of supply-water pump 120 extends on the intermediate wall portion 143 that the water supply cell wall angle 4 with the ice making wall angle 5 of refrigerating chamber 3 and refrigerator 1 separates.Drain hose 141 links to each other with the drain hose 142 at ice making wall angle 5.

More particularly, tube connector 150 is fixed on as shown in figure 29 the pars intermedia bulkhead 143, and the fore-end of delivery hose 141 is connected on the lower end connecting portion 151 of tube connector 150.Also have, the major diameter that the top of delivery hose 142 is inserted in the upper part of tube connector 150 is inserted in the section 152, admits by being placed on a seal 153 that inserts in the section 152.

Seal 153 is made by silicon rubber or other material that similarly can prevent air and seepage, and a plurality of circular protrusions 154 are arranged on its outer surface, and a plurality of sharp-pointed projectioies 155 are arranged on the surface within it.

As a result, the lower part of drain hose 142 is because the elasticity of seal 153 and fastened, therefore eliminated the danger that drain hose 142 and tube connector 150 separate.If fault has taken place in water supply cell wall angle 4 or ice making wall angle 5, as long as take off just can place under repair for the

drain hose

141 or 142 at that wall angle that will go out.

As shown in figure 21, so the drain hose 142 that connects is extended ice-making disc 149 places, at the front end of this drain hose 142 as shown in figure 30 a hat splashproof spare 145 is arranged.Therefore can prevent to splash, and can infeed water in the ice-making disc 149 by the water that drain hose 142 is discharged.It should be noted that label 146 is represented a sieve shape Flow-rate adjustment part of regulating current in the drain hose 142 in Figure 30.Though expressed aforesaid Flow-rate adjustment part 146 among Figure 30,, then can save it if added splashproof parts 145.If the front end at drain hose 146 is equipped with the Flow-rate adjustment part, then splashproof parts 145 just can save.

By the operation of the supply-water pump 120 of a control section 160 control and driving mechanism 100 as shown in figure 31.

Control section 160 confirms whether the water supply timing begins (the step S shown in Figure 32 ₁If) judge that the water supply timing does not begin, then driving mechanism 100 and supply-water pump 120 be inoperative state (as among Figure 31 at S ₁In be judged to be NO and then enter step S ₂And S ₃).

When the water supply timing began, then the valve 98 of driving mechanism 100 drive valve unit 93 moved up, as shown in figure 21, outlet 94 was opened for 7 seconds (later on this time is called T ₁) (if at step S ₁Middle judgement is YES, then enters step S ₄And S ₅).

Because outlet 94 continues to open as shown in figure 21, water can be flow in the water storage dish 110 by supply flume 90.When water surface curve Z had reached the bottom of the gauge line 95a that draws water, the air that enters the metering 95a that draws water was ended, and makes the water in the supply flume 90 stop to flow to 110.That is to say that 110 water fillings of water storage dish (claim that later on this time is T 5 seconds after the operation of driving mechanism 100 begins ₂).And, by T ₁To T ₂Time in, be full of in the ice-making disc 149 for the used water yield of ice-making disc 149.

" driving mechanism action " (the DRIVE MECHA-NISM ON) that describes among Figure 32 and 33 refers to that valve 98 has moved up so the state of delivery port 94 when having opened.T in addition ₁And T ₂Be not necessarily limited to 7 seconds and 5 seconds.That is to say, as long as T ₂Time be the time that water surface curve Z reaches the lower end of the gauge line 95a that draws water, and T ₁Compare T ₂Length just.

Then, at T ₁Second in the past rear drive mechanism 100 quits work, and supply-water pump 120 runnings are (as shown in Figure 32, as at step S ₅In be defined as YES and then enter step S ₆).Describe among Figure 32 and 33 " driving mechanism stops action (DRIVE MECH-ANISM OFF) and means that valve 98 has moved down, and delivery port 94 has been closed.

After supply-water pump 120 turned round for 14 seconds, supply-water pump 120 shut down (as shown in Figure 32 as at step S ₈In be judged to be YES and then enter step S ₉).As a result, supply-water pump 120 drew water from water storage dish 110 12 seconds, and during 12 seconds to 14 seconds, the water of being inhaled is supplied in the ice-making disc 149 as shown in figure 33.

So though be decided to be 14 seconds because the water in the water storage dish 110 must all be fed to the operating time of supply-water pump 120 in the ice-making disc 149, the present invention is to this not restriction.The operating time of supply-water pump 120 can be set up to the length with

drain hose

141 and 142 and be adapted.

The door of fixed or refrigerator 1 is opened and by having depressed Test Switchboard (omitting among the figure), the characteristic of supply-water pump 120 causes water to be stayed in soft suction hose 119 and

drain hose

141 and 142 if control section 160 is undesirably reseted.Therefore, in this state, if when supply-water pump 120 reruns, water that stays and the water in water storage dish 110 will be fed in the ice-making disc 149, and this does not wish to occur.In this case, just can not in ice-making disc 149, infeed the water of scheduled volume.Therefore, when control section 160 is reset or has pushed Test Switchboard, preferably allow supply-water pump 120 rotate a scheduled time without any exception, discharging at the water in soft suction hose 119 and

drain hose

141 and 142.

To the total operation according to the automatic icing equipment of present embodiment be described below.

Because action bars 101 do not moved downward when driving mechanism 100 moves, bar 97 overcomes the elastic force of spring 99 and moves downward, and therefore exports 94 and is closed by valve 98.

When driving mechanism 100 actions action bars 101 being moved upward, the upper surface of cap 102 moves up valve 98 and opens delivery port 94 to upper push-rod 97.The result flows in the water storage dish 110 from supply-water pump 120 by delivery port 94 water and is deposited in the water storage dish 110.Since sometimes the water yield of discharging from supply flume 90 slightly big flood will splash out by the diapire and the sidewall of water storage dish 110, so supply-water pump 120 will be placed on than on the high position of water storage dish 110, splash on the supply-water pump 120 to prevent water.

When water surface curve Z had gone up long lower end to the gauge line 95a that draws water, the air termination entered in the gauge line that draws water.Therefore supply flume 90 is ended to water storage dish 110 discharge waters.Thus, even driving mechanism 100 operations, water storage dish 110 also can continue to preserve and the corresponding water yield of ice-making disc 149 volumes.Therefore, even inhomogeneous, can not produce bad influence, so water storage dish 110 can continue to retain and the corresponding water yield of ice-making disc 149 volumes when the water flow velocity that the timing of driving mechanism 100 is broken down or delivery port 94 flows out.As previously mentioned, be full of water in the water storage dish 110, water is entered in the driving mechanism 100 irrelevantly, still,, driving mechanism 100 has been sealed fully, thereby prevented that water is introduced into driving mechanism 100 because cap 102 is arranged.

In this case, if driving mechanism 100 quits work, action bars 101 moves down and contacts with cap 102.At this moment,, therefore promote action bars 101 upwards, move downward to it and bring interference because the air in the cap 102 can produce the buoyance lift effect.But the air that can make in the cap that moves downward of action bars 101 is discharged by the groove 105 of pad 103.As a result, cap 102 shrinks immediately and makes driving mechanism 100 can have fabulous response characteristic.

As a result, the bar 97 of valve cell 93 in view of the above, cuts out outlet 94 by valve 98 owing to the active force of spring 99 moves downward, and supply flume 90 stops discharge water.

When almost stopping with driving mechanism 100 operations, supply-water pump 120 begins to move by soft suction hose 119 water in the water storage dish 110 is upwards inhaled.

Because the front end 119a of soft suction hose 119 is contained on the diapire of water storage dish 110 with pressing, and this moment soft suction hose the edge of front end 119a and the basal surface of groove 111 be skewed, so the water in the water storage dish 110 can be sucked out fully and effectively from the bottom surface.And the inside diameter D of soft suction hose 119 is less, is about 6mm improving the vacuum of soft suction hose 119, and makes the function of supply-water pump 120 more can be satisfactory.

Therefore, the water that is discharged in the water storage dish 110 by supply flume 90 can be drunk up immediately, and water in water storage dish 110 and the contacted time of air in the refrigerator 1 are shortened greatly.The smell that the result is spread out of by food in the refrigerator 1 and make ice problem odorous also obtain preventing.And, eliminated the rough sledding that the bacterium that suspends in the air is invaded basically, make water be unlikely to be clamminess and to foul.

Since water in water storage dish 110 by soft suction hose 119 from its upwards sucking-off of bottom, therefore owing to drop accidentally some pot foods such as crumbs etc. of user can be blocked by the upper surface of filter 112.So, owing to pot foods are fallen into the phenomenon that supply-water pump 120 damages the engagement between gear screw rod 124 and 1255 and just can be avoided.Can remove these chips by filter 112 being taken off and it being cleaned from water storage dish 110.

By the gear screw rod 124 of supply-

water pump

120 and 125 rotation, the water that sucks in the soft suction hose 119 is sent in the delivery hose 141.

If when producing vibrations owing to the rotation of the engagement of

gear screw rod

124 and 125 and motor 121, because supply-water pump 120 is fixed on the water storage dish 110, supply-water pump is contained in (shown in Figure 27 and 28) in the shock-resistant member 130 simultaneously, has therefore prevented the propagation of vibrating noise.

Water in the drain hose 141 upwards flows in the drain hose 142 that links to each other by tube connector 150.

Because drain hose 142 is by by silicon rubber or similarly can prevent seal member 153 clampings that material that the sky G﹠W infiltrates is made, the vacuum between

drain hose

141 and 142 can meet the demands.The result has prevented from bleeding unwelcome air and supply water owing to water bleeds to influence effectively to ice-making disc 149 from tube connector 150 between

drain hose

141 and 142.

If fault has taken place at ice making wall angle 5, just can repair easily as long as take off drain hose 142.Because what protrude to form on the outer surface of seal 153 a plurality of protruding 154 is circular, and the surface forms a plurality of pointed protrudingly 155 within it, and above-mentioned pointed projection can embed drain hose 142, so drain hose 142 can move smoothly.In addition, seal 153 is connected on the drain hose 142 when unloading scupper hose 142, so desirable lower seal.And when assembling parts once more,, scupper hose 142 is linked to each other at an easy rate with scupper hose 141 as long as with seal 153 simple insertions in the insertion parts 152.

Upwards be pressed into water in

drain hose

141 and 142 and can reach the end of drain hose 142.

By the internal diameter of

drain hose

141 and 142 being reduced under the predetermined value and improving the vacuum of

drain hose

141 and 142, can prevent that sealing undesirably stays in supply-water pump 120 and

drain hose

141 and 142, water all can be fed in the ice-making disc 149 again.Thereby prevented because resident water and the problem of breed bacteria in supply-water pump 120 and

drain hose

141 and 142.

By the opening that forms on drain hose 142 ends, the water that enters in the drain hose 142 can be discharged in the ice-making disc 149.

Because hat splashproof parts 145 as shown in figure 30 are housed in the end of drain hose 142, prevented that the water of discharging in the discharge pipe 142 from splashing and water is infeeded in the ice-making disc 149.If flow regulating part 146 is placed on the position of splashproof parts 145, water is slowed down by flow regulating part 146 and infeeds in the ice-making disc 149 again, also can prevent to cause to splash.

Figure 34 is the sectional view according to the automatic ice-making plant of sixth embodiment of the invention.

Present embodiment is that ice-making disc is placed on than on the low position of supply flume with the 5th embodiment difference.In the following description, with the 5th embodiment in identical parts represent with identical label.

Temperature sensor 211 is placed near ice-making disc 210 places, and it is used to judge whether water has supplied with ice-making disc 210.

Specifically, if the control of control panel 50 by being used for automatic ice-making plant among the first and the 5th embodiment and control section 160 is after ice-making disc supplies water, temperature does not rise yet, just judge and do not have water (omitting among the figure) in the supply flume, and send operation signal E by temperature sensor 211 to indicator lamp 212 immediately, switch 213 is connected indicator lamp 212, and indicator lamp is bright.

For example, temperature sensor 211 and switch 213 can be made of thermostat.

The effect of switch 213 is after it receives signal E, makes to realize between power supply 214 and the door open-close discriminating unit 220 being electrically connected, and actuating doors ON/OFF discriminating unit 220.

Door open-close discriminating unit 220 for example can be made of a microcomputer, and comprise that a transmission has the timer of the clock signal K of a preset frequency, one is sent the expression count signal N of gate time and the counter of computing time 222 according to clock signal K, and a processing section 223 of finishing predetermined process according to count signal N.

Predetermined fiducial time of the T that is stored in the memory 223 is read in processing section 223, and to fiducial time T and count signal N make comparisons.If the time ratio time T of being represented by count signal N is long, the signal V of the operation that stops to supply water is sent to the water supply control section that comprises control panel 50 and control section 160 etc. in the processing section, and it is used part in the automatic ice-making plant among first embodiment or the 5th embodiment that above-mentioned control panel and control part grade.Then, reset signal R is sent to counter 222 in the processing section.Processing section 223 is connected with the door open-close sensor of installing near the door 7 of refrigerator 1 230.

The ON/OFF of door open-close sensor 230 reflection doors 7 is the detection signal P that open or close to send reflection door 7 to the processing section.When processing section 223 receives detection signal P, just send water supply operation signal W, so that the water supply control section is finished the operation of supplying water.Then, stop signal S is sent in processing section 223 ₁, to close door open-close discriminating unit 220 and deenergization 214, a shutdown signal S is also sent in processing section 223 ₂, to close indicator lamp 212.

Operation to water supply detecting unit with this structure describes below.

If the user has by mistake placed an empty supply flume, then the operation that water is fed to ice-making disc 210 will can not make environment temperature raise.

Therefore, under aforesaid state, temperature sensor 211 sends an operation signal E to indicator lamp 212 and switch 213, so that lamp 212 lights and make switch 213 to connect, and makes 220 operations of door open-close discriminating unit.

Then, 220 beginnings of door open-close discriminating unit are sent clock signal K to counter 222, and therefore, counter 222 will send processing section 223 to according to clock signal K count signal N that calculate and that reflect the time.

Processing section 223 is by reading T fiducial time in the memory 224, and fiducial time T and count signal N make comparisons.If time ratio T fiducial time by count signal N reflection is long, just, if after enabling gate ON/OFF discriminating unit 220 through T fiducial time, then judging does not have water in the supply flume.Therefore, stop signal V is sent to the water supply control section in processing section 223, to stop the operation of supplying water.With the above-mentioned processing while, reset signal is sent to counter 222 in processing section 223, so that its reclocking.Aforesaid operations is repeated in processing section 223 behind the interval of T fiducial time.

If within fiducial time T, door 7 is ON/OFF, and as shown in figure 41, the open/close door open-close sensor 230 of reflection door 7 sends detection signal P to processing section 223.As a result, water supply operation signal W is sent to the water supply control section in processing section 223, to be finished the operation of supplying water by this water supply control section.Then, stop signal S is sent to switch 213 and indicator lamp 212 in processing section 223 ₁With shutdown signal S ₂, turning off door open-close discriminating unit 220 and power supply 214, and turn off indicator lamp 212.

As mentioned above, even setting is the sky supply flume, the automatic ice-making plant with above-mentioned water supply detecting unit has only the operation of just supplying water when supply flume is water-filled.Therefore, prevented owing to supply flume is the empty problem that ice can be made of not having.And the water supply detecting unit can be made of the microprocessor simple in structure of an electricity.Therefore, the supply flume that has complex mechanical construction that can omit as shown in figure 46 is provided with detecting unit.
