BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. First, a schematic basic configuration will be described.

The private parts washing water inspection device 10 (hereinafter abbreviated as “inspection device 10”) is an inspection device for inspecting the water pressure of the washing water discharged from the private parts washing device 20 toward the private parts. This inspection apparatus 10 is configured to include a surface pressure detection unit 11 , a pressure distribution calculation unit 12 , and a display unit 13 . Each part has an operation configuration described below.

The surface pressure detection unit 11 applies the washing water discharged from the private washing device 20 to the matrix-shaped inspection surface 11b, and detects the water pressure of the washing water (pressure against the inspection surface 11b) for each element 11c of the matrix. Eggplant. The pressure distribution calculation unit 12 integrates the water pressure for each element 11c of the matrix for a plurality of times periodically measured by the surface pressure detection unit 11 within a predetermined time to obtain the pressure distribution. The display unit 13 operates to display the pressure distribution obtained by the pressure distribution calculation unit 12 .

Next, the detailed configuration, operation and inspection output examples of the inspection apparatus 10 will be described. FIG. 1 is a basic block diagram of a private cleansing water inspection system 1 (hereinafter abbreviated as "inspection system 1") including the basic configuration of this inspection apparatus 10 and a private cleansing apparatus 20. As shown in FIG.

This inspection apparatus 10 is configured to be operated independently by an inspector without being connected to the private parts washing apparatus 20, and can be inspected while being operated. That is, washing water discharged by operating the private washing device 20 can be received by the matrix-shaped surface pressure sensor 11a of the inspection device 10 and inspected (local manual inspection). However, in the present embodiment, an inspection system 1 (system manual, automatic, fully automatic inspection) in which the inspection device 10 and the private parts washing device 20 are connected and cooperated for inspection will be illustrated and explained.

In order to operate in such an inspection system 1, the inspection apparatus 10 includes an operation unit 15 for inputting an inspection instruction such as an instruction to discharge water to the private parts washing apparatus 20, and an operation unit 15 for inputting an inspection instruction such as a water discharge instruction to the private parts washing apparatus 20. The configuration further includes a control unit 14 that outputs an inspection signal such as a water discharge command to the supply unit 21 .

The private parts washing device 20 includes a washing water supply section 21 , an examination signal input section 22 for receiving an examination signal from the examination apparatus 10 , and a washing operation section 23 . The cleansing water supply unit 21 can discharge cleansing water at different water supply pressures. The washing operation unit 23 has various switches for starting and ending washing (spraying water), setting the water supply pressure, etc. when washing the private part. Thus, the "water supply pressure" represents the discharge strength of cleansing water in the private parts washing device 20, and is distinguished from the "water pressure" obtained by inspection in this specification.

In this inspection system 1 , the cleaning water supply unit 21 operates based on the inspection signal input by the inspection signal input unit 22 instead of the operation from the cleaning operation unit 23 of the private parts cleaning device 20 . For example, when the inspection device 10 is connected to the device, the private parts washing device 20 may determine that it is in the inspection mode and switch the input to the inspection signal input section 22 . In the case of local manual inspection without receiving instructions from the inspection device 20, the cleaning operation unit 23 receives various operations and discharges cleaning water, while the inspection device 10 performs the inspection alone. . The inspection device 10 and the private cleaning device 20 may be connected by wire or wirelessly.

The inspection apparatus 10 includes a surface pressure detection unit 11, a pressure distribution calculation unit 12, a display unit 13, a control unit 14, and an operation unit 15, as shown in FIG. Each of these units is composed of a personal computer (CPU, program, etc.).

The surface pressure detection unit 11 includes the matrix-shaped surface pressure sensor 11a described above, as well as an input/output unit 11d, an A/D converter 11e, a PLC (programmable logical controller) 11f, and the like.

The surface pressure sensor 11a is a flat panel body, and elements 11c are arranged in a matrix of rows and columns (for example, 44×44) so that pressure can be measured by each element 11c. One of the surfaces of the panel is used as an inspection surface 11b on which the discharged cleaning water hits.

The input/output unit 11d is controlled by the PLC 11f to switch rows (or columns), and sensing can be performed for each row (or column). The PLC 11f inputs the detection information for each row (or column) via the A/D converter 11e. In addition, the PLC 11f may be switched so that all rows (or columns) can be measured at a sampling period of 100 Hz, for example.

More specifically, as shown in FIG. 2, the surface pressure sensor 11a includes two films 11aa, and silver electrodes 11ab in rows and columns are wired respectively. A pressure-sensitive conductive ink 11ac is coated on the silver electrode 11ab. The intersection of the row and the column becomes a sensing point, and when pressure is applied, the upper and lower pressure-sensitive conductive inks 11ac come into contact with each other and the electrical resistance value changes. In the case of this inspection apparatus 10, washing water hits the inspection surface 11b from the direction of the white arrow in FIG. comes into contact.

The intersections between the upper and lower pressure-sensitive conductive inks 11ac are the matrix elements 11c (see FIG. 1). The electric resistance value is converted into a digital value by an A/D converter and read into a personal computer. Note that the pressure value applied to the surface pressure sensor 11a and the electrical resistance value are in an inversely proportional relationship.

When inspecting, the center of the surface pressure sensor 11a should be placed in an appropriate position so as not to shift left and right when viewed from the nozzle position of the cleansing water supply unit 21 of the private washing device 20 incorporated in the toilet bowl device (not shown). It is desirable that it be placed in the center position, ie, the center position of the buttocks when a person sits correctly on the toilet seat.

In this inspection system 1, the washing water discharged from the private washing device 20 hits one surface (inspection surface 11b) of the surface pressure sensor 11a, and pressure is applied to the hit portion (one or a plurality of elements 11c). It is configured to detect water pressure by changing the resistance value.

In this way, the water pressure value (unit: Kgf/cm 2 ) of the washing water discharged from the private parts washing device 20 is measured for each element 11c of the matrix.

As described above, since the surface pressure sensor 11a is of a resistance type, the water pressure value can be obtained from the electric resistance value, and the inspection apparatus 10 can be configured which can easily measure the water pressure at the same position as the inspection surface 11b. can be done.

This inspection apparatus 10 obtains the water pressure for each element 11c by integrating pressure values over a predetermined period of time. This predetermined time is, for example, one to several seconds, and the measurement may be performed, for example, 30 to 300 times during that time. This predetermined time is determined by the control unit 14 issuing a start command to the private washing device 20 and an operation instruction for the time until the end by operating the operation unit 15 of the inspection device 10 to start discharging cleansing water. good. In this manner, the control unit 14 outputs various water discharge commands to the private parts washing device 20 .

FIG. 3 is a time chart of water pressure measurement. When the surface pressure sensor 11a (inspection surface 11b) is being sprayed with cleansing water from the private washing device 20, when the surface pressure detection unit 11 receives a measurement start command, within a predetermined period of time, A pressure value (water pressure value) is measured at each periodic measurement timing, and the water pressure value is integrated by the pressure distribution calculation unit 12 . This is done for each element 11c. This measurement timing may be measured on either the surface pressure detection unit 11 (PLC 11f) side or the personal computer side. Needless to say, a clock (timer) is necessary for this purpose.

As shown in FIG. 3, washing water is discharged from the private washing device 20 at a generally constant water supply pressure (no pulsation) for a predetermined period of time, or the water supply pressure changes in a constant cycle. (There is pulsation). As for water supply with pulsation, it is desirable that the predetermined time spans over a plurality of cycles, as shown in the figure.

In order to carry out the water pressure test for a predetermined time, it is necessary to output a water discharge command (measurement start command and measurement time or measurement end command) from the control unit 14 to the private washing device 20 according to an instruction from the operation unit 15. Just do it.

As described above, in this embodiment, the water pressure value is accumulated by sampling multiple times during a predetermined time, and the strength of the water pressure for each element 11c is determined based on the total value. Therefore, even if the wash water collides with the surface pressure sensor 11a and bounces off, and the rebounding water collides with the spouted wash water and changes its direction or water pressure, the measurements are averaged a plurality of times. , strength can be determined appropriately. Also, even in the case of cleaning with pulsation, by measuring and integrating over a plurality of cycles, the water pressure can be appropriately determined without zero integration occurring within the timing when cleaning water is not discharged.

The water pressure value integrated for each element 11c by the pressure distribution calculation unit 12 in this way is displayed on the display unit 13 in various formats. For example, three-dimensional graphs as shown in FIGS. 4A and 4C and two-dimensional graphs as shown in FIGS. 4B and 4D may be displayed. The three-dimensional graph may be displayed in different colors depending on the water pressure strength, that is, the height of the graph. Since it can be graphed in this way, the state of water pressure can be expressed numerically and left.

4A and 4B are graphs for low water supply pressure, and FIGS. 4C and 4D are graphs for high water supply pressure. In order to display such a graph, it is necessary to determine a reference level, and the reference level can be determined by performing no-load measurement in which washing water is not discharged.

Comparing the case of low water supply pressure and the case of high water supply pressure, the part that hits the low water supply pressure wash water is in front of the high water supply pressure, and the water pressure of the low water supply pressure wash water is high water supply pressure. is displayed smaller (lower height) than

In the example of this embodiment, as shown in FIG. 4, the measured water pressure has a large integrated amount in the center and a small integrated amount in the surrounding area. A proper splash distribution of the wash water can be determined, not too dispersed. In particular, when the water supply pressure is high, the spread between the front and back of the wash water is small, and it can be judged from the graph that the target is pinpointed.

According to the three-dimensional graphs of FIGS. 4(a) and 4(c), whether or not the water pressure is appropriate can be determined for each part based on the height. Also, according to the two-dimensional graph, it can be determined whether or not the cleansing water is being discharged to an appropriate position. Also, as shown in FIGS. 4(b) and 4(d), the position where the wash water hits due to the low water supply pressure and the high water supply pressure is shifted back and forth. can be determined by In addition, the color-coded display makes it possible to determine the appropriate water pressure for each stage in the portion that is strongly hit by the washing water.

Next, automatic system inspection by the inspection system 1 will be described.

In the water pressure value measurement described above, if the water pressure is set by the operation unit 15 of the inspection device 20 and then water discharge is started, the system can be manually inspected so that the total value of the water pressure value at that water pressure can be calculated. ing. If you change the water supply pressure and measure it, you can repeat the system manual test.

However, in order to perform inspections more efficiently, the inspection system 1 can perform automatic inspections and fully automatic inspections. In either case, the automatic switch or full-automatic switch can be started from the operation unit 15 of the inspection apparatus 10 . In addition, in these execution modes, since a plurality of water supply pressure inspections are continuously performed, it is sufficient to allow the setting of the water supply pressure to be changed and the interval between different water supply pressure inspections to be set.

In the case of automatic inspection, as shown in FIG. 5, inspection is first performed without water supply (no load) (S101, S102), then inspection is performed for cleaning with low water supply pressure according to the set value (S103, S104), and then the set value. Accordingly, an inspection is performed for washing with high water supply pressure (S105, S106). Finally, the low water supply pressure and the high water supply pressure are displayed graphically (S107).

That is, the control unit 14 is configured to output to the private washing device 20 a pressure-changed water discharge command that is a combination of a water supply pressure setting change and a water discharge command after the setting change. In the case of the system manual inspection, the pressure-changed water discharge command is output once, but in the case of the automatic inspection of FIG. A continuous check for low water supply pressure and high water supply pressure is performed.

In the case of the fully automatic inspection, the inspection is repeated twice for washing the buttocks and washing the bidet. At the first time, the nozzle of the cleansing water supply unit is moved to the bottom position (S201, S202), and inspections are sequentially performed for no water supply, low water supply pressure, and high water supply pressure (S205 to S210). In the second time, the nozzle of the cleansing water supply unit is moved to the bidet position (S201, S203, S204), and inspections are sequentially performed for no water supply, low water supply pressure, and high water supply pressure (S205 to S210). After the two inspections are completed, graphs are displayed for both the buttocks and the bidet (S211).

In the case of the fully automatic inspection of FIG. 6 as well, the controller 14 repeatedly outputs the pressure change water discharge command twice at regular time intervals, so that the continuous inspection of low water supply pressure and high water supply pressure is performed. In the fully automatic case, the continuous operation is repeated twice.

In addition, in the automatic and fully automatic inspection, the example of changing two stages of low water supply pressure and high water supply pressure was shown above, but according to the number of stages of water supply pressure of the private washing device 20, It is also possible to perform an inspection in which the water supply pressure is changed three or more times.

If the inspection is performed automatically or fully automatically as described above, results can be efficiently obtained in a short time. In the fully automatic inspection, the inspection may be performed by combining the buttocks washing and the bidet washing with no pulsation and with pulsation. It goes without saying that various other inspection combinations can be applied.
