Abstract
The present invention relates to a drum-type washing machine. The invention settles a problem of ensuring enough washing capacity even at the states when a user performs secondary washing or immersion washing, etc. When a washing operation is started at a no-water state of a water-containing barrel (31), which is detected by a water level sensor (45), the washing operation is performed in the washing process according to the dirty degree determination result obtained from an optical sensor (72). When the washing operation is started at a water existing state, which is detected by the water level sensor, the dirty degree determination result which is obtained according to the optical sensor in the washing process is fixed to a stage with most dirt. Therefore, even when the secondary washing is performed or the washing operation is started at the water existing state in the water-containing barrel for immersion washing, sufficient washing capacity is ensured similarly with the normal operation when the washing is started from the no-water state of the water-containing barrel.

On the one side opposite, be provided with discoideus thick meat part 738 and columned electrode part 739 with the bending direction of the edge part 735,736 of terminal board 731.Terminal board 731 is connected through the base end part of thick meat part 738 with electrode part 739.The base end part of electrode part 739 chimeric O shape circle 371.Electrode part 739 is inserted in the through hole 773 on the straight sections 701 of casing 70 of draining control module 7 (with reference to Fig. 2).
Utilize setting tool that terminal board 731 is crimped on after the outside of straight sections 701, the O shape circle 371 that is installed in the base end part of electrode part 739 will be compressed.O shape is enclosed 371 resiliency and is inserted in the setting tool in the through hole 311, can make terminal board 731 produce bending moments.Sweep extends along the orientation of a pair of through hole 311, and the left and right edges of terminal board is crooked along sweep, and therefore, terminal board 731 has the high rigidity to Resisting Bend Moment.So, just can be installed in terminal board 731 outside of straight sections 701 with very strong power.So the O shape circle 371 that is arranged on the base end part of electrode part 739 is compressed by powerful, thereby can bring into play good sealing property.Therefore, just can prevent effectively that cleaning solution from leaking the situation of coming out through the through hole 773 that is opened in straight sections 701.In addition, though in this example, sweep 734 is a right angle intersection with axle Ma,, sweep 734 is not have special qualification with the intersecting angle of axle Ma.Also have, in this form of implementation, though be expressed as through hole 311 to fixed part; But; The present invention is not limited to this mode, also can use other fixedly gimmick, for example; Can be to utilize clamping device terminal board 731 being crimped onto the fixedly gimmick of the outer wall of straight sections 701, or be crimped onto terminal board 731 with enough big power the outer wall of straight sections 701 for the sealing function of bringing into play O shape circle.But, using under the situation of clamping device, is that part ofly to be played a role terminal board 731 as fixed part by what clip was clamped.
Figure 11 is the cutaway view that the straight sections 701 of terminal board 731,732 has been installed in expression.Figure 11 (a) is that expression is positioned at the terminal board 731 of upstream side and the cutaway view around the electrode part 739, and Figure 11 (b) is that expression is positioned at the terminal 732 in downstream and the cutaway view around the electrode part 739.
Figure 12 is the sketch map of the flow condition of the cleaning solution around the analog representation electrode part 739.In addition, in Figure 12, the electrode part that is arranged on upstream side indicates symbol 739a, and the electrode part that is arranged on the downstream indicates symbol 739b.
Shown in figure 12, the 739a of pair of electrodes portion, 739b are arranged side by side along the length direction of straight sections 701, spool parallel to each other by axle determined plane P and the straight sections 701 of the 739a of pair of electrodes portion, 739b.The electrode part 739a that is positioned at upstream side can be shunted along the moving cleaning solution of the axial flow of straight sections 701 along the vertical direction, so the flow that passes the cleaning solution of plane P can tail off.Therefore, for the electrical conductivity of measuring cleaning solution can descend the flowability of cleaning solution, thereby obtain the flowing velocity of the cleaning solution of suitable electrical conductivity mensuration in the interval of suitable electrode part 739a, 739b (for example below the above 30mm of 15mm).
In addition, shown in figure 12, with comprise the 739a of pair of electrodes portion, 739b the axle plane P be horizontal plane.The top, inner space that the 739a of pair of electrodes portion, 739b can not pass straight sections 701 is (in the design of draining control module 7; (for example might produce space that air accumulates; In straight sections 701 inner spaces 1/5 zone, top)) and the bottom, inner space of straight sections 701 (in the design of draining control module 7; Might pile up the space (for example, the zone of below 1/5 in straight sections 701 inner spaces) of dirt composition).Therefore, the whole face of the ledge of electrode part 739a, 739b can both contact with the cleaning solutions in the straight sections 701, just can suppress the interior air of straight sections 701 mensuration of electrical conductivity is exerted an influence.And, since electrode part 739a, 739b give prominence in the inner space of straight sections 701 above in 4/5 the zone, so just can suppress to be deposited in the interior dirt composition of straight sections 701 mensuration of electrical conductivity is exerted an influence.
Figure 13 is the sketch map of the flow condition of the cleaning solution around analog representation optical pickocff 72 and the electrode sensor 73.In Figure 13, the light-emitting component 721 of the optical pickocff 72 that combination Fig. 7 to Fig. 9 describes and the optical axis 250 of the IR between the photo detector 722 have also been represented.In addition, the same with Figure 12, the electrode part that is arranged on upstream side indicates symbol 739a, and the electrode part that is arranged on the downstream indicates symbol 739b.
For the IR that prevents to form optical axis 250 produces unnecessary refraction, the upstream-side-end 277 of formed smooth inner face 772 is swelled in other internal faces relatively on straight sections 701 internal faces.Therefore, upstream 277 can be upset flowing of cleaning solution.For this reason, accomplish rectification before, preferably it is arranged on the position of leaving optical axis 250 upstream side enough far away in order to let being flowing in of cleaning solution arrive optical axis 250.Like this, the cleaning solution that passes optical axis 250 could form appropriate current, meets the requirement of doing the cleaning solution turbidimetry of judgement according to the light quantity of the IR of the photo detector 722 of the optical pickocff 72 that arrive to combine Fig. 7 to Fig. 9 to describe.The IR of optical pickocff 72 can be to any influence of mobile generation of cleaning solution.So the mobile meeting of cleaning solution arrives electrode part 739a, 739b under the state after the rectification.
As the combination explanation that Figure 12 did, the part of the current parallel with the direction of principal axis of straight sections 701 is split into two parts up and down by the electrode part 739a of upstream side.Therefore, the mobile quilt of cleaning solution has been upset.Because the disorder that the cleaning solution that is caused by this electrode part 739a flows is to occur in the downstream that combines the optical pickocff 72 that Fig. 7 to Fig. 9 describes, so can not produce any influence to the turbidimetry that optical pickocff 72 is implemented.
As the combination explanation that Figure 12 did, be parallel to each other by the determined plane P of axle of electrode part 739a, 739b and the axle of straight sections 701.So; For example; In straight sections 701, let under the situation of cleaning solution reverse flow (direction of 311 discharge 311 (with reference to Fig. 1)) from straight sections 701 toward steel ladle; Though electrode part 739b can shunt the current of cleaning solution up and down, electrode part 739a is overlapping with electrode part 739b in the flow direction of cleaning solution, so can exceedingly not upset flowing of cleaning solution.So, even, also can go out turbidity with higher accuracy detection through the cleaning solution of optical axis 250 letting under the situation of cleaning solution reverse flow.
On the lower limb 392 on the downside border of the smooth inner face 702 of the top edge 391 of the boundary of the smooth inner face 702 of decision and decision, the cross section profile shape of straight sections 701 presents bow shape (with reference to Fig. 7).Compare other parts, the current of cleaning solution present the part generation delay of bow shape easily in this cross section profile shape.Shown in figure 13, the part in the cross section that is arranged so that electrode part 739a, 739b of electrode part 739a, 739b enters among the smooth inner face 702.Because cleaning solution rests on near the top edge 391 of electrode part 739a, 739b clamping especially easily, can obtain to measure the current of the required suitable lazy flow of cleaning solution electric conductivity.And, through letting between electrode part 739a, the 739b plane P confirmed parallel with top edge 391, the mensuration precision of step raising electrical conductivity more.
Let us describes referring to figs. 1 through Fig. 5 once more.Be provided with circulating pump 71 in the downstream of electrode sensor 73.Between the casing 70 of circulating pump 71 and draining control module 7, be provided with suction line 711, this suction line 711 comprise the end that is connected with the suction inlet of circulating pump 71, with the casing 70 of draining control module 7 on offer the other end that the 2nd peristome 771 of formation is connected.The 2nd pipeline 52 extends out from the delivery outlet of circulating pump 71.The inflow 312 of offering formation on the 2nd pipeline 52 and the steel ladle 31 is connected.
Figure 14 is the analog representation cleaning solution flows to the mobility status of circulating pump 71 from electrode sensor 73 a plane.During with reference to Figure 14, can be in the lump with reference to Fig. 1 and Fig. 2.In Figure 14, represented suction line 711.Shown in figure 14, electrode sensor 73 is arranged on than the connecting portion 771 (in Fig. 2, being expressed as the 2nd peristome 771) of suction line 711 and draining control module 7 position at the upper reaches more.And the same with Figure 12, the electrode part that is arranged on upstream side indicates symbol 739a, and the electrode part that is arranged on the downstream indicates symbol 739b.
Formed straight stream (in Figure 14, with dashed lines is represented the boundary line of straight sections 701 and containing tube portion 702) in the straight sections 701 of the casing 70 of formation draining control module 7 and 702 views of containing tube portion.Suction line 711 and straight sections 701 are connected with containing tube portion 702 formed straight streams.711 of suction lines towards with different direction (in the structure of draining control module 7 shown in Figure 14, be the right angle orientation) extension of bearing of trend of the formed straight stream of straight sections 701 and containing tube portion 702.Along the cleaning solution of straight flow path, change flow direction after receiving the attraction of self-circulating pump 71, then flow to suction line 711.Therefore,, the cleaning solution current of symmetrical VELOCITY DISTRIBUTION Vp1 are arranged in plan view with respect to axle at the straight stream at the upper reaches, the containing tube portion 702 around connecting portion 771 with and/or the inner space of straight sections 701 have asymmetrical VELOCITY DISTRIBUTION Vp2.Asymmetrical VELOCITY DISTRIBUTION Vp2 towards the containing tube portion 702 of connecting portion 771 with and/or the inside pipe wall of straight sections 701 near a high-speed region is arranged.Electrode sensor 73 is outstanding from the inner face towards the straight sections of connecting portion 771 sides.In addition; So-called " towards the inner face of connecting portion 771 sides "; Be meant that when the longitudinal axis of straight sections 701 and containing tube portion 702 is separated straight sections 701 and containing tube portion 702 inner face from connecting portion 771 position far away is a basic point with the axle of suction line 711; As preferably, be meant to be positioned at 3 times in the upper reaches and/or downstream or 4 times inner face zone to the containing tube portion of the distance of suction line 711 internal diameters 702 and/or straight sections.Even more ideal; Be meant that axle with suction line 711 is basic point, is positioned at 3.5 times in the upper reaches and/or the downstream inner face zone to the containing tube portion of the distance of suction line 711 internal diameters 702 and/or straight sections; Even more ideal, be meant that the axle with suction line 711 is a basic point, be positioned at 3 times in the upper reaches and/or downstream inner face zone to the containing tube portion of the distance of suction line 711 internal diameters 702 and/or straight sections.Near this inner face zone, can produce high-flow area.The electrode part 739a of electrode sensor 73,739b are outstanding from this inner face zone, and cross high-flow area.
In Figure 14, expression be any 2 P1 and the P2 that crosses near the cross section C of the pipelines electrode sensor 73.Point P1 is for leaving near the arbitrfary point of connecting portion 711 a distance (just the face of connecting portion 711), and some P2 compares a P1 from connecting portion 711 arbitrfary point more nearby.On a P1, flow to the speed V1 of the cleaning solution of leading section from the base end part of electrode part 739a, 739b, bigger than the equidirectional speed V2 on a P2.Therefore, be arranged on electrode sensor 73 on the position of connecting portion 711, just can assist in removing the line bits that hang on the electrode sensor 73.
As stated, electrode part 739a, 739b form protuberance in straight sections 701.Therefore, the line bits that comprised in the cleaning solution of inflow draining control module 7 are hung over electrode part 739a easily, 739b is last.But, because electrode part 739a, the 739b of electrode sensor 73 cross high-flow area, so hang over electrode part 739a, the bits of the line above the 739b relatively easily from electrode part 739a, 739b removal.In addition, as shown in Figure 2, owing in the containing tube portion 702 filter part 76 is housed, so the part of filter part 76 (with reference to Fig. 1) is between electrode sensor 73 and connecting portion 771.In Figure 14, roughly represented filter part 76 with the zone of drawing shade.Therefore, cleaning solution is after through the electrode sensor 73 that is positioned at filter part 76 upstream positions, and arrival is positioned at before the suction line 711 of filter part 76 downstream positions, is arranged on the filter part 76 of taking in the pipeline 702 with passing earlier.So,, can be filtered device portion 76 and catch from the line bits that electrode part 739a, 739b remove.And filter part 76 suppresses the effect that electrode part cleaning solution on every side flows for the mobile drag effect that played of cleaning solution rapidly so can also stop the back performance at circulating pump 71.
Figure 15 is the line bits are removed in explanation with circulating pump 71 and draining valve 75 a sketch map.To be the analog representation cleaning solution flow to the plane of the mobility status of circulating pump 71 from electrode sensor 73 to Figure 15 (a), and Figure 15 (b) is the analog representation cleaning solution flows to the mobility status of draining valve 75 from electrode sensor 73 a plane.During with reference to Figure 15, can be in the lump with reference to Fig. 1.In addition, the suction line 711 and the discharge pipe line 74 that forms the stream that arrives draining valve 75 of the stream that arrives circulating pump 71 in Figure 15, have also been represented to form.And the same with Figure 12, the electrode part that is arranged on upstream side indicates symbol 739a, and the electrode part that is arranged on the downstream indicates symbol 739b.In addition, Figure 15 (a) is the same with simulation drawing shown in Figure 14, also is to compare for the nowed forming with the cleaning solution shown in Figure 15 (b).
Shown in figure 15, electrode sensor 73 is preferably disposed on the upper reaches of connecting portion 771 (the 2nd peristome 771) of downstream, the suction line 711 of the connecting portion 774 (the 1st peristome 774) of discharge pipe line 74.Electrode sensor 73 is arranged on such position, and after draining valve 75 was opened, at the outstanding pipeline portions that exists of electrode part 739a, 739b, cleaning solution in the opposite direction flowed in the time of will producing with circulating pump 71 actions.Like this, hanging over the last line bits of electrode part 739a, 739b will be easy to remove from electrode part 739a, 739b.
Figure 16 is the sketch map of circulating pump 71.Figure 16 (a) is the cutaway view of expression circulating pump 71, and Figure 16 (b) is the plane of expression circulating pump 71, and Figure 16 (c) is the sketch map of the circulating pump 71 looked sideways from suction inlet of expression.

Figure 17 is the sketch map of the connecting portion structure of expression steel ladle 31 and the 2nd pipeline 52.Figure 17 (a) is the plane of the pipeline of formation connecting portion, and Figure 17 (b) is the transverse sectional view of pipeline shown in Figure 17 (a), and Figure 17 (c) is the longitudinal sectional view of pipeline shown in Figure 17 (a).
The inflow entrance 312 of steel ladle 31 is made up of the muscle 121 of the ring-type of up giving prominence to from steel ladle 31 outer walls.Inner peripheral surface along ring-type muscle 121 is equipped with O shape circle 122.O shape circle 121 is pushed down by pipeline 520.
Be equipped with swing roller 32 in the inside of steel ladle 31.Be equipped with between the top and inflow entrance 312 of swing roller 32 and stop wall 126.Stop wall 126 supporting by the connecting wall 127 that the outer wall with steel ladle 31 is connected.Stop wall 126 to form narrow stream with throttling wall 123.This narrow flow path plays the effect of arriving spraying cleaning solution the jet 129 in the washtub 3.
Through the cleaning solution after the jet 129 that forms by prevention wall 126 and throttling wall 123; Subsequently the part of the outside through constituting steel ladle 31 and and the front bulkhead 321 of throttling wall 126 front bulkhead 128 that presses O shape circle 122 jointly and swing roller 32 between the stream 281 of formation, be transported to the inside of swing roller 32.
The leading section 128 of steel ladle 31 and the leading section 321 of swing roller 32 have formed the export department 282 of ring-type.Through the cleaning solution after the stream 281,, sprayed to the rotary middle spindle of swing roller 32 through after the export department 282 of ring-type.Through the cleaning solution that export department 282 ejects, be ejected into the inboard rotary area of swing roller 32 effectively.Therefore, cleaning solution can be flowed to washings effectively, and irrelevant with the quantity of the swing roller 32 interior washings that held.
(forming the one side of stream 281) comprises inclined plane 283 and flexure plane 284 at the back side of steel ladle 31 front bulkheads 128.Inclined plane 283 reduces the sectional area downstream direction of stream 281 gradually, and therefore, the flow velocity of the cleaning solution through stream 281 will correspondingly be accelerated gradually.So, flow to flexure plane 284 while accelerate flow velocity through the cleaning solution of stream 281.The flow direction that flexure plane 284 changes cleaning solution makes it flow to the bottom of swing roller 32.So the cleaning solution that ejects from export department 282 can flow to the bottom of swing roller 32.So, just can offer washings to cleaning solution effectively.
The cover 524 of pipeline 520 can adopt simple installation constitution, forms the stream that flows to inflow entrance 312.Can utilize shape and size, the shape of connecting wall 127 and the shape and the size of size and prevention wall 126 of the cover 524 that covers inflow entrance 312, guarantee that cleaning solution flows in the swing roller 32 with suitable current.Can be through the design parameter of setting cover 524, connecting wall 127 rightly and stoping wall 126, the appropriateness of the flow width of the cleaning solution that guarantees to eject from ejiction opening 129, the numerical value of flow thickness and flowing velocity.Through such mode, just can offer washings to cleaning solution effectively, and irrelevant with the quantity of the swing roller 32 interior washings that held.
The installation constitution of the cover 524 of pipeline 520 shown in Figure 17 and connecting wall 127 and stop the structure of wall 126 all very simple both can drop to the danger that will leak minimumly, helped to reduce manufacturing cost again.
As stated, pipeline 520 utilizes second pipeline 523 to form the stream that flows to inflow entrance 312 with cover 524.As shown in Figure 1, this stream extends along the outer surface of steel ladle 31.So, be set as rectangle to second pipeline 523 with cover 524 formed pipeline cross sections, form a smooth pipeline, just can in the small gap between steel ladle 31 and the casing 2, form pipeline.In addition, through forming a smooth pipeline, just can form shape and the flow width of size and a flow of liquor of the thickness that flows with suitable jet 129.Cleaning solution can let cleaning solution obtain rectification, and flow to jet 129 through smooth pipeline.
On the front bulkhead 321 of swing roller 32, be provided with many prominent bars 322.Prominent bar 322 extends in the specific length scope of the circumferencial direction of the front bulkhead 321 of swing roller 32.Many prominent bars 322 in the position of circumferencial direction and/or the position of radial direction can be different.Prominent bar 322 makes the sectional area part of stream 281 in downstream of jet 129 diminish.Near export department 282, utilize prominent bar 322 that flow path cross sectional area is dwindled situation; Compare with leaving the situation that export department 282 a distance utilize prominent bar 322 that flow path cross sectional area is dwindled, the motion track of the cleaning solution that ejects from export department 282 is different.Therefore, the cleaning solution that ejects from export department 282 can spill cloth on a large scale in swing roller 32, just can to washings cleaning solution be provided efficiently.
The shape of prominent bar 322 is not limited to the shape shown in Figure 17.For example, prominent bar 322 both can be corrugated, also can be penniform.In a word, prominent bar 322 can adopt arbitrary shape, as long as can change from the motion track of the cleaning solution of export department's 282 discharges.In addition, prominent bar 322 can also adopt any configuration mode that can change from the motion track of the cleaning solution of export department's 282 discharges.
Stop between wall 126 and the swing roller 32 and formed space 261.When circulating pump 71 low-speed runnings (for example: 1000 rev/mins), cleaning solution is from jet 129 inflow spaces 261.Flow into cleaning solution after the space 261 along the spatial flow of 31 of swing roller 32 and steel ladles outlet 311 to steel ladle 31.
That Figure 18 representes is an embodiment of the functional configuration of control loop portion 81.
Figure 19 is the chart of expression according to the transmissivity P of the washings that output obtained of optical pickocff 72, and transmissivity P is high more, explains that the transparency of washings is high more.In addition; Figure 19 (a) is a chart of representing generally to carry out washing for the 1st time the washing process when turning round; Figure 19 (b) is expression: in the 1st time the washing running after washing process finishes, cutting off the electricity supply before the beginning draining shuts down, and from washtub, takes out the washings that washes, and once more other washings is dropped into logical again going up after the power supply in the washtub; Carry out the 2nd time washing with same cleaning solution, just the chart of the washing process under 2 washing situation.
Shown in Figure 19 (a); Be P (AIR) according to the transmissivity P that output obtained of optical pickocff 72 is very high when start of run is anhydrous state; T (1) after the washing agent in running water and washing agent accommodation section (not the illustrating) arrives the water level flood optical pickocff 72 temporarily is shown as minimum P value (MIN), but thin out along with continuation of intaking and detergent concentration; Transmissivity P can rise gradually; After being transformed into washing process from the water inlet process, when washing process initial stage t (2), be expressed as transmissivity P (2), t after washing process begins certain hour (3) is expressed as transmissivity P (3).
Figure 20 representes is to the transmissivity P according to the washings that output obtained of the set optical pickocff 72 of storage part 816, an example of the corresponding data configuration of cleaning solution degree of fouling threshold value.With reference to Figure 20, and in the lump with reference to Figure 18 and Figure 19, for example clear state in the steel ladle during according to the washing beginning utilizes the gimmick of the degree of fouling of different threshold determination cleaning solutions.
Shown in Figure 19 (a); Detection unit 814 begins the transmissivity P (2) of washing process initial stage t (2) and washing process the difference DELTA P of the transmissivity P (3) of t (3) behind the certain hour; Compare with the threshold value shown in figure 20 in the storage part 816, just can make judgement the degree of fouling of cleaning solution in the washing process such as " many ", " many slightly ", " few slightly ", " lacking " 4 grades.
On the other hand; Shown in Figure 19 (b), for example, when carrying out 2 washings; If the washings that drops into for the 2nd time is identical with primary degree of fouling; Because the transmissivity P (2 ') of washing process initial stage t (2) is very low, itself and washing process begin the difference DELTA P ' between the transmissivity P (3 ') of t (3) behind the certain hour, compare with Δ P to seem less relatively.
In this case, if detection unit 814 is still done identical comparison with Δ P ' with the threshold value shown in figure 20 in the storage part 816 with Δ P, even the washings pollution level that drops into is identical, also the decision content condition of different may appear.For example, even the 1st time identical with the washings pollution level that drops into for the 2nd time, judgement that maybe the 1st time is that " many slightly ", the 2nd time judgement but are " lack ", and the result will be absorbed in the situation that the 2nd time washing can't obtain sufficient clean effect.
At this moment, always be fixed on " many " shown in Figure 20 through judging the degree of fouling that the situation that begins to wash running under the water state is arranged in the steel ladle, so, even carried out washing for 2 times or also can fully guarantee washing (-)off properties during washing by soaking.
In addition; When 2 washings; Because the interfacial agent in 1 washing in the washing agent is consumed, causes and clean effect decline, so if the washings of in 2 washings, washing is not very dirty; Even under the state that is fixed on degree of fouling " many " shown in figure 20, wash running, can not waste the duration of runs yet and make water consumption.And; When washing by soaking, although in immersion process because the emulsification of washing agent is dissolved out greasy dirt etc., soaking the dirty washings of washing generally all contains dirts such as silt particle, dust; The inorganic foulants that these washing agent can't be removed needs abundant stirring just can remove; So likewise, even under the state that is fixed on degree of fouling " many " shown in figure 20, wash running, can not waste the duration of runs yet and make water consumption.
Though in above-mentioned explanation; The electrode sensor 73 that is used for measuring electrical conductivity is give an example as the sensor that protrudes in stream to represent; But principle of the present invention is not limited to this; The washing machine of any sensor that must directly contact with cleaning solution so long as be used for the rerum natura that detects cleaning solution can be suitable for.
Though in above-mentioned explanation, optical pickocff 72 is the turbidities that are used for measuring cleaning solution, also can be used for other and measures purpose.Principle of the present invention can either be applicable to as detecting dirt composition piles up and the optical pickocff 72 of use, also applicable to other rerum naturas or the environmental change that are fit to utilize optical pickocff 72 to measure.So optical pickocff 72 is not defined and can only be installed in the pipeline that constitutes stream, it also can be entrenched in be full of cleaning solution any space (for example: the wall portion somewhere that forms the steel ladle wall of steel ladle 31).
