Figure 10 is the skeleton diagram of terminal board 731.Figure 10 (a) is the side view of terminal board 731.Figure 10 (b) is the front view of terminal board 731.Simultaneously with reference to Figure 10, Fig. 3 and Fig. 6.In addition, shape and the big I in conjunction with the terminal board 732 in the downstream of Fig. 2 to Fig. 6 explanation is identical with terminal board 731.
On the face of the opposite side of the overbending direction with edge part 735,736 of terminal board 731, be formed with discoideus heavy section 738 and columned electrode portion 739.Terminal board 731 is connected with the base end part of electrode portion 739 by heavy section 738.Chimeric on the base end part of electrode portion 739 have an O type ring 371.Electrode portion 739 is inserted on the straight sections 701 of basket 70 of draining control module 7 in the formed through hole 773 (with reference to Fig. 2).
Be formed with a pair of through hole 310 on the terminal board 731.The through hole 310 of one of them is positioned at the top of electrode portion 739.Another through hole 310 is positioned at the below of electrode portion 739.A pair of through hole 310 and electrode portion 739 arrange along the vertical direction.The line parallel of the central point of folding line 734 and a pair of through hole 310 of binding.Be inserted with the fixture of bolt and so in the through hole 310.Like this, through hole 310 is installed in terminal board 731 fixed part on the outside of straight sections 701 and brings into play function as being used for.
If utilize fixture that terminal board 731 is crimped on the outside of straight sections 701, the O type ring 371 that then is installed on the base end part of electrode portion 739 is compressed.The restoring force of O type ring 371 and the fixture that inserts in the through hole 310 make terminal board 731 produce bending moment.Bend along the folding line that extends in the orientation of a pair of through hole 310 by the left and right edges that makes terminal board 731, terminal board 731 has higher rigidity with respect to bending moment.Therefore, terminal board 731 can be fixedly mounted on the outside of straight sections 701.Its result, the O type ring 371 of base end part that is arranged on electrode portion 739 is because of the effect that is subjected to stronger power is compressed, thus the performance high sealing performance.Like this, can suppress cleaning solution aptly leaks by formed through hole 773 on the straight sections 701.In addition, in the present embodiment, folding line 734 is vertical with the axle of bending moment, but the angle of reporting to the leadship after accomplishing a task of the axle of folding line 734 and bending moment is not particularly limited.In addition, in the present embodiment, through hole 310 is shown as fixed part, but also can replace, adopt and for example to utilize anchor clamps (clamp) terminal board 731 to be crimped on the fixedly gimmick of the outer wall of straight sections 701, or other fixing gimmicks that adopt the outer wall that terminal board 731 can be crimped on straight sections 701 in order to make the environment-development of O type wave sealing function with enough big power.In addition, when using anchor clamps, terminal board 731 brought into play function by the part of anchor clamps clamping as fixed part.
Figure 11 is the cutaway view that the straight sections 701 of terminal board 731,732 is installed.Figure 11 (a) is positioned at the terminal board 731 of upstream one side and the cutaway view around the electrode portion 739.Figure 11 (b) is positioned at the terminal board 732 of downstream one side and the cutaway view around the electrode portion 739.
The cleaning solution that the smooth inner face 772 of crosscut straight sections 701 is contained in the inner outstanding electrode portions 739 of straight sections 701 and straight sections 701 contacts.Apply high-frequency ac voltage by 733 pairs of terminal boards of electric wire 731,732, the electrical conductivity of existing cleaning solution between the pair of electrodes portion 739 (impedance (impedance)) is measured.
Figure 12 is the schematic diagram that flows of the cleaning solution around the electrode portion 739.In addition, among Figure 12, the electrode standard laid down by the ministries or commissions of the Central Government of upstream is annotated symbol 739a, the electrode standard laid down by the ministries or commissions of the Central Government in downstream is annotated symbol 739b.
As shown in figure 12, the 739a of pair of electrodes portion, 739b are along the length direction alignment arrangements of straight sections 701.By the plane P that defines of the 739a of pair of electrodes portion, 739b and an almost parallel of straight sections 701.The 739a of electrode portion of upstream will be along the moving cleaning solution above-below direction shunting of the axial flow of straight sections 701.The flow of the cleaning solution of therefore, crosscut plane P reduces.Its result, the space (for example space more than the 15mm and below the 30mm) between the 739a of electrode portion, the 739b of the electrical conductivity that is suitable for measuring cleaning solution, the flowability of cleaning solution reduces.Like this, can obtain to be suitable for to measure the flowing of cleaning solution of electrical conductivity.
In addition, as shown in figure 12, the plane P that comprises the axle of the 739a of pair of electrodes portion, 739b is a horizontal plane.Comparatively it is desirable to, all (space that air trapping might take place because of the design reasons of draining control module 7 (for example on the top, inner space of not crosscut straight sections 701 for the 739a of pair of electrodes portion, 739b, and the bottom, inner space of straight sections 701 (might pile up the space (for example, the zone of the downside 1/5 in the inner space of straight sections 701) of dirty composition because of the design reasons of draining control module 7) zone of the upside 1/5 in the inner space of straight sections 701)).Its result, whole of the ledge of the 739a of electrode portion, 739b contacts with cleaning solution in the straight sections 701.Therefore, the air in the straight sections 701 is inhibited to the influence of the measurement of electrical conductivity.In addition, when giving prominence in the zone of the 739a of electrode portion, the 739b upside 4/5 in the inner space of straight sections 701, the dirty compositions of piling up in the straight sections 701 can be inhibited to the influence of the measurement of electrical conductivity.
Figure 13 schematically shows flowing of optical sensor 72 and electrode sensor 73 cleaning solution on every side.Shown in Figure 13 is the light-emitting component 721 of the optical sensor 72 that illustrates in conjunction with Fig. 7 to Fig. 9 and the light path 250 of the IR between the photo detector 722.In addition, identical with Figure 12, the electrode standard laid down by the ministries or commissions of the Central Government that is arranged at upstream one side is annotated symbol 739a, the electrode standard laid down by the ministries or commissions of the Central Government that is arranged at downstream one side is annotated symbol 739b.
The upstream-side-end 277 of the smooth inner face 772 that forms at the internal face of straight sections 701 for the unnecessary refraction of the IR that prevents to form light path 250 is from other internal face protuberance.Therefore, upstream-side-end 277 confuses flow of liquor.Therefore, entirely arrive light path 250 in order to make flow of liquor, upstream-side-end 277 is formed on fully away from the position of upstream one side of light path 250 comparatively desirable.At this moment, the cleaning solution of crosscut light path 250 becomes the liquid stream of the measurement of the turbidity that is suitable for cleaning solution, and wherein, the turbidity of cleaning solution is according to the light quantity of the IR of the photo detector 722 that arrives the optical sensor 72 that illustrates in conjunction with Fig. 7 to Fig. 9 and estimative.The IR of optical sensor 72 can not bring any influence to cleaning solution mobile.Therefore, the flow of liquor after the rectification arrives the electrode 739a of portion, 739b.
As illustrated, shunt up and down by the part of liquid stream that the 739a of electrode portion of upstream will be parallel with the direction of principal axis of straight sections 701 in conjunction with Figure 12.Its result, flow of liquor is disturbed.By the confusion of the caused flow of liquor of the 739a of electrode portion is to produce in the downstream of the optical sensor 72 that illustrates in conjunction with Fig. 7 to a Fig. 9 side, therefore can bring influence to the measurement of the turbidity of optical sensor 72 hardly.
As illustrated, by the plane P that defines of the 739a of electrode portion, 739b and an almost parallel of straight sections 701 in conjunction with Figure 12.Therefore, for example, when making cleaning solution in straight sections 701, reflux (from the direction of straight sections 701) towards the outlet 311 (with reference to Fig. 1) of tank 31, though the 739b of electrode portion shunts flow of liquor up and down, but owing to the 739a of electrode portion overlaps with the 739b of electrode portion on the flow direction of cleaning solution, so can not confuse to transition flow of liquor.Therefore, even when cleaning solution refluxes, also can be to pass through the turbidity of the cleaning solution of light path 250 than higher accuracy detection.
At the top edge 391 on the border of the upside of the smooth inner face 772 of regulation, and lower limb 392 places on the border of the downside of the smooth inner face 772 of regulation, straight sections 701 forms the cross section profile shape (with reference to Fig. 7) that is bent into concavity.Compare the easier part that forms this curved cross section contour shape that is trapped in of flow of liquor with other parts.As shown in figure 13, the 739a of electrode portion, the 739b part that is configured to its cross section enters in the smooth inner face 772.Near the top edge 391 that is clipped in the middle by the 739a of electrode portion, 739b, cleaning solution is detained especially easily, and the liquid of lazy flow that therefore can obtain to be suitable for to measure the electric conductivity of cleaning solution flows.In addition, plane P of stipulating between the 739a of electrode portion, 739b and top edge 391 almost parallels further improve the certainty of measurement of electrical conductivity thus.

According to said structure, by the electrical conductivity of sensor measurement cleaning solution, the concentration of the kind of contained washing agent or washing agent is detected in the cleaning solution.In addition, as mentioned above,, therefore reduced the influence of velveteen to the measurement of electrical conductivity owing to promoted to remove velveteen from sensor.In addition, be accompanied by removing of promotion velveteen, utilize the electrode portion that protrudes in significantly in the cleaning solution to realize the measurement of the electrical conductivity of degree of precision.
In said structure, comparatively it is desirable to, described sensor be set at be subjected to from described outlet towards described aspiration first-class to flow of liquor and with this first-class position to reverse second flow of liquor that flows to.
According to said structure because sensor is subjected to second cleaning solution that flows to, therefore remove easily first-class to cleaning solution in the velveteen that is difficult to remove.
In said structure, comparatively it is desirable to, also comprise the discharge pipe line that is connected and discharges described cleaning solution with described pipeline to the outside, this discharge pipe line compare with the described connecting portion of described aspiration be positioned at described first-class to the upstream, described sensor compare with described connecting portion be positioned at described first-class to the upstream, but compare with the connecting portion of described pipeline and described discharge pipe line be positioned at described first-class to the downstream.
According to said structure, from discharge pipe line to the outside discharge cleaning solution during sensor around flow of liquor, for the flow device duration of work first-class to the second reverse flow of liquor that flows to of flow of liquor.Therefore, by discharging cleaning solution via discharge line, the velveteen that is hooked on the sensor is removed easily.
In said structure, comparatively it is desirable to, also comprise the filter house of removing dirty composition contained in the described cleaning solution, this filter house be set at described sensor near.
According to said structure, the velveteen of removing from protuberance is captured by filter house.Because the filter house performance is blocked in the effect of the flow of liquor that flows in the pipeline, therefore after flow device stops, can in the relatively shorter time, reducing the liquidity of cleaning solution.Therefore, even when sensor is subjected to influencing of flow of liquor easily to the measurement of the physical characteristic of cleaning solution, also can be in the relatively shorter time and with the physical characteristic of higher precision measure cleaning solution.
In said structure, comparatively it is desirable to, at least a portion of described filter house is present between the described connecting portion of described sensor and described aspiration.
According to said structure, filter house is being brought into play the effect that stops flow of liquor between the connecting portion of sensor and aspiration.Therefore, the influence from flow device by the cleaning solution transmission obtains relaxing.Like this, even when sensor is subjected to influencing of flow of liquor easily to the measurement of the physical characteristic of cleaning solution, the physical characteristic of precision measure cleaning solution that also can be higher.
In said structure, comparatively it is desirable to, described pipeline comprises straight sections that described sensor is outstanding and the receipts filling tube part that is connected and accommodates described filter house with this straight sections and described aspiration, and described receipts filling tube part tilts upward with respect to described straight sections.
According to said structure, the bubble that flows into straight sections is flushed to the receipts filling tube part and is difficult to and returns from the receipts filling tube part.Therefore, bubble is difficult to be trapped in straight sections, though sensor to the measurement of the physical characteristic of cleaning solution be subjected to easily that bubble exists in the pipeline influence the time, also can be in the relatively shorter time and with the electrical conductivity of higher precision measure cleaning solution.In addition, because receiving the head of the cleaning solution in the filling tube part is suppressed at the signal that flow device is stopped and sends the unnecessary flow of liquor that the back produces because of the inertia motion of flow device, therefore even when sensor is subjected to influencing of flow of liquor easily to the measurement of the physical characteristic of cleaning solution, the physical characteristic of precision measure cleaning solution that also can be higher.
