FIG. 14 is a block diagram of the cleaning property evaluation apparatus of the third embodiment of the present invention. The cleaning property evaluation device 60 is a device that transmits light to the cleaning property evaluation jigs 21 and 40 cleaned by the cleaning device 10 and measures the residual oil amount by the transmitted light.

The cleaning property evaluation device 60 is composed of the cleaning property evaluation jig 2
1 or a stand 65 on which the cleaning property evaluation jig 40 is placed, a light source lamp 61 for irradiating the cleaning property evaluation jigs 21, 40 with light, and a light receiving element module for receiving the light transmitted through the cleaning property evaluation tools 21, 40 ( A light receiving unit 62, a control unit (control unit) 63 that measures the residual oil amount, and a display unit (display unit) 64 that displays the residual oil amount and the like are provided. FIG. 14 shows an example in which the cleaning property evaluation jig 21 is placed on the stand 65.

When the cleaning performance evaluation jig 21 is used, the cleaning performance evaluation jig 21 which is cleaned by the cleaning device 10 after filling the tap holes 22 with oil is placed on the stand 65 of the light source lamp 61. It is placed in accordance with the irradiation position and the position of the light receiving portion of the light receiving element module 62. At this time, as shown in FIG. 14, the washability evaluation jig 21 is placed so that the tapped holes 22 extend in the vertical direction (KL direction in FIG. 14).

When the cleaning property evaluation jig 40 is used, the cleaning device 1 is installed on the stand 65 after filling the gap 51 with oil.
The cleaning property evaluation jig 40 cleaned with 0 is the light source lamp 61.
And the light receiving part of the light receiving element module 62. At this time, for example, the mounting table 65 is so arranged that the clip 44 extends in the vertical direction (KL direction in FIG. 14).
It is mounted on top of the transparent acrylic plates 41 and 42 so that the irradiation light from the light source lamp 61 passes vertically through the transparent acrylic plates 41 and 42.

The light source lamp 61 is turned on by the controller 63, and irradiates the portion of the cleaning property evaluation jigs 21 and 40 for measuring the residual oil content with light.

As the cleaning property evaluation jig, the cleaning property evaluation jig 40 was used.
When the light is transmitted by mounting it on the stand 65, a measurement area including the vicinity of the centers of the transparent acrylic plates 41, 42 where residual oil is generated is set, and the transmitted light in this measurement area is received by the light receiving element module 62. Receive light. Therefore, the light source lamp 61
Is capable of irradiating light to the entire measurement area.

The light-receiving element module 62 is composed of, for example, a photodiode array and has a light-receiving portion spreading in a plane. The light receiving portion of the light receiving element module 62 has an area capable of receiving all the transmitted light in the measurement region of the cleaning property evaluation jig 40.

The light-receiving element module 62 generates a light-reception signal corresponding to the amount of light received for each photodiode of the light-reception section and supplies it to the control section 63.

The control unit 63 controls ON / OFF of the light source lamp 61 in accordance with the operation of an operation switch (not shown),
When the light source lamp 61 is turned on, the amount of residual oil in the cleaning property evaluation jig 21 or the cleaning property evaluation jig 40 is calculated based on the light reception signal supplied from the light receiving element module 62.

When the cleaning property evaluation jig 21 is used, a light reception signal corresponding to the amount of light received of the transmitted light through any one of the tap holes 22 to be measured can be obtained. When there is no residual oil 36, the amount of received light is the largest and the received light signal is large. As the amount of residual oil 36 is larger, the amount of received light is smaller and the received light signal is smaller. The control unit 63 uses the received light receiving signal,

Switch to. With this setting, the control unit 63 selects only the light reception signal of the diode array that receives the transmitted light of the tap hole 22 to be measured, out of all the diode arrays that form the light reception unit, and uses it for the calculation of the residual oil content. . As a result, the influence of light transmitted through the other tap holes 22 can be eliminated.

When the cleaning property evaluation jig 40 is used, a light reception signal corresponding to the received light amount of the transmitted light transmitted through the measurement area including the vicinity of the centers of the transparent acrylic plates 41 and 42 can be obtained. When there is no residual oil content 56, the amount of received light is the largest, the received light signal is large, and as the amount of residual oil 56 increases and the area in the measurement region is wider, the amount of received light is smaller and the received light signal is smaller. The control unit 63 uses the received light receiving signal,
For example, what percentage of the area of the measurement region the residual oil content 56 is is calculated, and the calculation result data is supplied to the display unit 64.

The display unit 64 displays the calculation result of the residual oil content supplied from the control unit 63 as the measurement result of the residual oil content. As the display unit 64, for example, a configuration in which a number is displayed by a multi-digit number display, a configuration in which a number is displayed on a display such as a CRT, or a percentage of the residual oil content of the measurement result is used.
It is possible to have a configuration in which a plurality of lamps provided corresponding to the above are turned on.

The correspondence between the amount of residual oil and the cleaning performance evaluation value of the cleaning device is stored in the control unit 63 in advance as data, and the control unit 63 determines the cleaning performance of the cleaning device from the residual oil content. It is also possible to calculate the evaluation value of 1 and display the cleaning performance evaluation value on the display unit 64.

As described above, in the cleaning property evaluation apparatus 60 of this embodiment, the cleaning property evaluation jig 2 cleaned by the cleaning device 10 is used.
Only by setting 1, 40, it is possible to automatically measure an accurate residual oil amount, and to evaluate the cleaning performance of the cleaning device 10 more easily and accurately than in the case of visual evaluation. be able to.
