However, as the signal transmission method of the external remote controller 62, a method different from the signal transmission method of the remote controller 11 may be used.

An example of the inspection procedure according to the inspection mode (hereinafter referred to as “the main inspection procedure”) according to the present embodiment will be described with reference to FIGS. 5 to 7. The main inspection procedure described below is performed by the CPU of the second microcomputer 20 reading and executing a predetermined inspection program stored in a storage device such as a RAM. This inspection program is a program for causing the CPU of the second microcomputer 20 which is connected to each functional unit of the second functional unit group and controls these functional units to execute this inspection procedure.

In this inspection procedure, pass / fail judgments are made for each functional part of the cover-side assembly 60 in a predetermined order, and the inspection is interrupted when a failure judgment result is obtained for the functional parts to be inspected. To. That is, the inspection is continued as long as the pass judgment result continues to be obtained for the functional part to be inspected.

As shown in FIG. 5, in this inspection procedure, first, power is supplied from the outside (S10). That is, an external power source 61 such as a commercial power source is connected to the second microcomputer 20, and power is supplied from the external power source 61 to the second microcomputer 20.

Next, an inspection signal is transmitted from the external remote controller 62 to the cover-side assembly 60 (S20). In this step, the inspection signal 63 is transmitted from the external remote controller 62 to the cover-side assembly 60 by the operator operating a predetermined operation point such as the inspection start button of the external remote controller 62.

The inspection signal 63 transmitted from the external remote controller 62 is received by the remote controller receiving unit 19 of the cover-side assembly 60 (S30). Here, when the remote control receiving unit 19 normally receives the inspection signal 63 and the remote control receiving unit 19 normally transmits the signal to the second microcomputer 20, the second microcomputer 20 enters the inspection mode (S40). In this way, the second microcomputer 20 executes the inspection mode when the remote controller receiving unit 19 receives the inspection signal 63, which is a signal for starting the inspection mode.

When the second microcomputer 20 enters the inspection mode, all the light emitting units 17a, 17b, 17c, and 17d of the display unit 17 are lit in blue, and the sound generating unit 18 generates a notification sound (buzzer). , A control signal is sent to the display unit 17 and the sound generation unit 18.

That is, when at least one of the display unit 17 and the sound generating unit 18 operates, the remote control receiving unit 19 normally receives the inspection signal 63 and the remote control receiving unit 19 normally transmits the signal to the second microcomputer 20. It is confirmed that it was done. Since the inspection signal 63 is normally received by the remote control receiving unit 19, the inspection of the remote control receiving unit 19 is passed.

Further, in step S50, each of the display unit 17 and the sound generation unit 18 is inspected depending on whether or not they operate. That is, when all the light emitting units 17a, 17b, 17c, and 17d of the display unit 17 are lit, it is confirmed that the display unit 17 is normal, and in other cases, the inspection of the display unit 17 is rejected. Become. Further, when the notification sound is generated from the sound generating unit 18, it is confirmed that the sound generating unit 18 is normal, and in other cases, the inspection of the sound generating unit 18 fails.

When the display unit 17 and the sound generating unit 18 operate normally (S50, Yes), the inspections of the remote control receiving unit 19, the display unit 17, and the sound generating unit 18 pass, and this signals the start of the inspection (S60). ). On the other hand, if either one or both of the display unit 17 and the sound generating unit 18 do not operate (S50, No), the inspection fails and the inspection is interrupted (S70). Here, when both the display unit 17 and the sound generating unit 18 do not operate, it includes a case where the remote control receiving unit 19 is not operating normally, that is, a case where the inspection of the remote control receiving unit 19 fails.

When the inspection is started in step S60, the inspection of the human body detection sensor 12 is performed first (S80). Here, it is confirmed whether or not the human body detection sensor 12 can detect a person. The second microcomputer 20 sends a signal for executing the inspection to the human body detection sensor 12. Then, by performing a predetermined detected operation on the human body detection sensor 12, the second microcomputer 20 determines whether or not the human body detection sensor 12 operates normally based on the signal received from the human body detection sensor 12. To do.

As the detected operation for the human body detection sensor 12, an operation that imitates the movement of the human body detected by the human body detection sensor 12 in the toilet device 1 is performed. Specifically, for example, a detection target for inspection is within the detection range of the human body detection sensor 12 so that the positional relationship is similar to the positional relationship between the human body detection sensor 12 in the toilet device 1 and the human body detected by the sensor 12. By positioning the object, the detection operation of the human body detection sensor 12 is confirmed.

In step S80, when the second microcomputer 20 determines that the human body detection sensor 12 is normal (S80, Yes), the first light emitting unit 17a as the LED 1 is lit in green as shown in FIG. 7 (b). Then, the green display 17G is performed (S90). In this case, the inspection of the human body detection sensor 12 passes.

On the other hand, in step S80, when the second microcomputer 20 determines that the human body detection sensor 12 is not normal (S80, No), the first light emitting unit 17a is turned on in red as shown in FIG. 7 (c). Red display 17R is performed (S100). In this case, the inspection of the human body detection sensor 12 fails, and the main inspection procedure is interrupted (S110).

After the green display 17G of the first light emitting unit 17a is performed by the display unit 17 in step S90, the seating detection sensor 13 is inspected as shown in FIG. 6 (S120). Here, it is confirmed whether or not the seating detection sensor 13 can detect the seating. The second microcomputer 20 sends a signal for executing the inspection to the seating detection sensor 13. Then, by performing a predetermined detected operation on the seating detection sensor 13, the second microcomputer 20 determines whether or not the seating detection sensor 13 operates normally based on the signal received from the seating detection sensor 13. To do.

As the detected operation for the seating detection sensor 13, an operation that imitates the movement of the human body detected by the seating detection sensor 13 in the toilet device 1 is performed. Specifically, for example, in the toilet device 1, when the user sits on the toilet seat 6, a load similar to the load detected by the seat detection sensor 13 is applied to the seat detection sensor 13, thereby causing the seat detection sensor 13. The detection operation of 13 is confirmed.

In step S120, when the second microcomputer 20 determines that the seating detection sensor 13 is normal (S120, Yes), the second light emitting unit 17b as the LED 2 is lit in green as shown in FIG. 7 (d). Then, the green display 17G is performed (S130). In this case, the inspection of the seating detection sensor 13 passes.

On the other hand, in step S120, when the second microcomputer 20 determines that the seating detection sensor 13 is not normal (S120, No), the second light emitting unit 17b is turned on in red as shown in FIG. 7 (e). Red display 17R is performed (S140). In this case, the inspection of the seating detection sensor 13 fails, and the main inspection procedure is interrupted (S150).

After the display unit 17 performs the green display 17G of the second light emitting unit 17b in step S130, the electric opening / closing unit 50 is inspected (S160). Here, the operation of the electric opening / closing unit 50A for the toilet seat and the electric opening / closing unit 50B for the toilet lid is confirmed. The second microcomputer 20 sends a predetermined control signal to the toilet seat opening / closing motor 51 and the toilet lid opening / closing motor 52 of each electric opening / closing unit 50, and the electric opening / closing unit 50 is based on the signals received from these motors. To determine if it works properly.

The second microcomputer 20 determines that the two electric opening / closing units 50 are normal only when both the toilet seat opening / closing motor 51 and the toilet lid opening / closing motor 52 operate normally. That is, the second microcomputer 20 does not determine that the electric opening / closing unit 50 is normal when at least one of the toilet seat opening / closing motor 51 and the toilet lid opening / closing motor 52 does not operate normally.

In step S160, when the second microcomputer 20 determines that the electric opening / closing unit 50 is normal (S160, Yes), the third light emitting unit 17c as the LED 3 is lit in green as shown in FIG. 7 (f). Then, the green display 17G is performed (S170). In this case, the inspection of the electric opening / closing unit 50 passes.

On the other hand, in step S160, when the second microcomputer 20 determines that the electric opening / closing unit 50 is not normal (S160, No), the third light emitting unit 17c is turned on in red as shown in FIG. 7 (g). Red display 17R is performed (S180). In this case, the inspection of the electric opening / closing unit 50 fails, and the main inspection procedure is interrupted (S190).

Here, the temperature detection by the toilet seat thermistor 16 is confirmed. The second microcomputer 20 sends a signal to the toilet seat thermistor 16 to execute the inspection. Then, by setting the toilet seat thermistor 16 to a predetermined detected temperature state, whether or not the toilet seat thermistor 16 operates normally in relation to a predetermined threshold value based on the signal received from the toilet seat thermistor 16 by the second microcomputer 20. To judge.

In step S200, when the second microcomputer 20 determines that the toilet seat thermistor 16 is normal (S200, Yes), as shown in FIG. 7 (h), the fourth light emitting unit 17d as the LED 4 is turned on in green. The green display 17G is performed (S210). In this case, the inspection of the toilet seat thermistor 16 passes.

On the other hand, in step S200, when the second microcomputer 20 determines that the toilet seat thermistor 16 is not normal (S200, No), as shown in FIG. 7 (i), the fourth light emitting unit 17d is turned on in red to be red. Display 17R is performed (S220). In this case, the inspection of the toilet seat thermistor 16 fails, and the main inspection procedure is interrupted (S230).

Regarding the inspection of the electric opening / closing unit 50, since the operation of the toilet seat opening / closing motor 51 and the toilet lid opening / closing motor 52 can be visually confirmed by the operator, the inspection result is displayed by the display unit 17. Can be omitted. As a process in this case, for example, when the second microcomputer 20 determines that the electric opening / closing unit 50 is normal in step S160, the second microcomputer 20 goes to the inspection (S200) of the toilet seat thermistor 16 without displaying the display on the display unit 17. If it is not determined in step S160 that the electric opening / closing unit 50 is normal, the process is interrupted.

After the display unit 17 performs the green display 17G of the fourth light emitting unit 17d in step S210, the second microcomputer 20 lights all the light emitting units 17a, 17b, 17c, and 17d of the display unit 17 in red and red. Display 17R is performed, and a predetermined notification sound is generated by the sound generation unit 18 (S240). As a result, the inspection of the cover-side assembly 60 to be inspected by this inspection procedure is passed (S250). That is, the display by the display unit 17 and the generation of the notification sound by the sound generation unit 18 in step S240 are signals for passing all inspections for the functional units to be inspected in the second functional unit group. This completes the main inspection procedure.

That is, in this inspection procedure, as the inspection result of the remote control receiving unit 19, the display unit 17 is lit and the sound generating unit 18 is notified by sound. Further, as the inspection results of the human body detection sensor 12, the seating detection sensor 13, the electric opening / closing unit 50, and the toilet seat thermistor 16, notification is performed by lighting the display unit 17. Further, as a signal of passing all the inspections, the display unit 17 is lit and the sound generation unit 18 is notified by sound.

As described above, in the sanitary cleaning device 2 of the present embodiment, the second functional unit group has a notification unit 65 for notifying the inspection result in the inspection mode, and the notification unit 65 is a display unit provided on the case cover 5b. 17 and a sound generating unit 18.

According to the sanitary cleaning device 2 according to the present embodiment having the above configuration, it is possible to improve the efficiency of the inspection process of the device / device built in the casing 5 of the device main body 4.

In the sanitary cleaning device 2 of the present embodiment, the case plate 5a is provided with the first functional unit group and the first microcomputer 10 for controlling these functional units, and the case cover 5b is provided with the second functional unit group and these. It is provided with a configuration provided with a second microcomputer 20 for controlling the functional unit of the above. That is, the second microcomputer 20 capable of controlling and driving all the functional units provided on the case cover 5b side is provided on the case cover 5b side.

According to such a configuration, in the manufacturing process of the sanitary cleaning device, before the cover side assembly 60 is combined with the plate side assembly 70, each functional unit is normally performed only on the cover side assembly 60 side. Since it is possible to inspect whether or not it operates, it is possible to improve the inspection efficiency. It will be described with reference to FIGS. 8 and 9 that such an effect can be obtained.

Here, as a configuration of a comparative example with respect to the sanitary cleaning device 2 according to the present embodiment, as shown in FIG. 9, only the operation of the electric opening / closing unit 50 is controlled instead of the second microcomputer 20 installed on the case cover 5b. A configuration including a cover-side assembly 60X having a control unit 20X for the electric opening / closing unit 50 on which the control circuit is mounted is used. That is, in the cover-side assembly 60X having the configuration of the comparative example, the control unit 20X controls only the electric opening / closing unit 50A for the toilet seat and the electric opening / closing unit 50B for the toilet lid, and the human body detection sensor 12, the seating detection sensor 13, and the like are used. , It is not connected to the functional units other than the electric opening / closing unit 50, and the control of these functional units is performed by the main control unit provided on the case plate 5a side.

In the manufacturing process of the sanitary cleaning device, the assembly on the case plate side for assembling the device / equipment to the case plate 5a and the assembly on the case cover side for assembling the device / equipment to the case cover 5b are mutually exclusive. It is done on separate lines. In the examples shown in FIGS. 8 and 9, the manufacturing line shown in the lower row is the main line 81 for assembling the case plate 5a side, and the manufacturing line shown in the upper row is the sub line for assembling the case cover 5b side. 82. FIG. 8 is an explanatory diagram of the inspection process of the sanitary cleaning device 2 according to the present embodiment, and FIG. 9 is an explanatory diagram of the inspection process in the case of the configuration of the comparative example. In the configuration of the comparative example, the configuration on the case plate 5a side to be combined with the cover side assembly 60X is referred to as the plate side assembly 70X.

As shown in FIG. 9, in the case of the configuration of the comparative example, in the main line 81, after the plate-side assembly 70X is assembled, an inspection step 83 for inspecting the plate-side assembly 70X is performed. In the inspection step 83, each functional part of the plate-side assembly 70X is inspected.

Similarly, in the case of the configuration of the comparative example, the cover-side assembly 60X assembled in the sub-line 82 is inspected for each functional part in a state of being combined with the plate-side assembly 70X that has passed the inspection in the inspection step 83. Receive. That is, the functional parts of the cover-side assembly 60X other than the electric opening / closing unit 50 are assembled on the plate side in the assembly 80 in the device state in which the cover-side assembly 60X and the plate-side assembly 70X are combined. It is inspected in the final inspection step 84 in a state of being connected to the main control unit of the body 70X. In the final inspection step 84, in addition to the inspection of the functional portion of the cover-side assembly 60X, an inspection before shipment in the product state such as power measurement is performed.

As described above, in the case of the configuration of the comparative example, for the functional parts other than the electric opening / closing unit 50 of the cover side assembly 60X, the cover side assembly 60X and the plate side assembly 70X are combined to form the plate side. It cannot be operated unless it is connected to the control unit of the assembly 70X. Therefore, in order to confirm the operation of each functional part of the cover side assembly 60X, that is, to inspect each functional part, the cover side assembly 60X and the plate side assembly are to be inspected. It is necessary to combine the 70X and connect the functional part of the cover side assembly 60 to the control part of the plate side assembly 70X.

Therefore, for example, in the final inspection step 84, when a defect such as a disconnection, an assembly error, or a malfunction is found in the functional part of the cover side assembly 60X, that is, when an abnormality is detected and the inspection fails. In order to identify, analyze, and correct the cause of the defect, it is necessary to disassemble the product, for example, disassembling the assembly 80 into the cover side assembly 60X and the plate side assembly 70X (FIG. 9, arrow B1). reference).

As a result, in the inspection process, so-called rework of returning to the previous stage and redoing the work occurs, and the inspection efficiency is lowered. Further, if the inspection in the final inspection step 84 is unsuccessful, the main line 81 itself is stopped, which has a great influence on the manufacturing process of the sanitary cleaning apparatus.

Further, according to the configuration of the comparative example, the connection targets of various devices / devices built in the casing 5 are concentrated on the main control unit provided on the case plate 5a side. For this reason, it takes time to insert and remove the connector for connecting the device / equipment to the control unit and to arrange the cable, and when an abnormality is found in the inspection process, the product must be disassembled and reassembled. It will be a heavy burden for the worker.

On the other hand, as shown in FIG. 8, according to the sanitary cleaning device 2 of the present embodiment, the plate-side assembly 70 is inspected after the plate-side assembly 70 is assembled in the main line 81. The inspection step 85 is performed. In the inspection step 85, the first microcomputer 10 connected to the power supply board 45 is used, and the operation of each functional unit of the first functional unit group of the plate-side assembly 70 is confirmed, that is, the first microcomputer 10 is connected to the first microcomputer 10. Each functional part is inspected.

Further, in the sub line 82, after the cover side assembly 60 is assembled, an inspection step 86 for inspecting the cover side assembly 60 is performed. In the inspection step 86, the inspection procedure in the inspection mode as described with reference to the flow charts shown in FIGS. 5 and 6 is executed.

Then, the plate-side assembly 70 that has passed the inspection in the inspection step 85 on the main line 81 and the cover-side assembly 60 that has passed the inspection step 86 on the sub-line 82 are combined, and in the final inspection step 87. , The assembly 90 in the device state is inspected before shipment in the product state such as power measurement.

As described above, according to the sanitary cleaning device 2 of the present embodiment, a second microcomputer 20 capable of controlling a plurality of functional units provided for the case cover 5b is provided on the case cover 5b side. Therefore, before assembling the cover-side assembly 60 and the plate-side assembly 70, the inspection can be performed only on the case cover 5b side under the operation control by the second microcomputer 20. That is, since the second microcomputer 20 that integrates the load control on the case cover 5b side is mounted on the case cover 5b side, the cover side assembly body 60 separated from the plate side assembly body 70 is in a single state. It becomes possible to inspect each functional part of the second functional part group.

Therefore, it is possible to detect a defect in the functional portion in the casing, particularly a defect in the functional portion provided on the case cover 5b side at an early stage. Further, even if the inspection of the cover side assembly 60 fails, the work of disassembling the product such as disassembling the assembly 90 into the cover side assembly 60 and the plate side assembly 70 does not occur. (See FIG. 8, arrow B2).

Therefore, it is possible to suppress the occurrence of rework, so that the burden on the operator can be reduced, the time loss can be reduced, and the inspection efficiency can be improved. Further, even if the inspection of the cover side assembly 60 fails, it is not necessary to stop the main line 81, so that the failure of the inspection of the cover side assembly 60 is included in the manufacturing process of the sanitary cleaning device 2. The impact can be reduced or eliminated. Further, in the final inspection step 87, the inspection of each functional part of the cover side assembly 60 has already been performed in the inspection step 86 in the sub line 82, so that the inspection content in the final inspection step 87 is greatly simplified. It becomes possible. As described above, according to the sanitary cleaning device 2 according to the present embodiment, the inspection process can be simplified.

Further, according to the sanitary cleaning device 2 according to the present embodiment, the connection target of each functional unit of the functional unit in the casing is distributed to the first microcomputer 10 and the second microcomputer 20. Therefore, in comparison with the configuration of the comparative example in which the connection target of the functional unit is concentrated on the first microcomputer 10, the number of electric wires forming the wire harness 30 connecting the first microcomputer 10 and the second microcomputer 20 (connector poles). Number) can be reduced. As a result, the space required for wiring the wire harness 30 in the casing 5 can be reduced, so that the casing 5 can be miniaturized and reduced in height.

Further, in the sanitary cleaning device 2 according to the present embodiment, the second microcomputer 20 automatically sets the operation mode to the normal use mode in which each functional unit is operated when the sanitary cleaning device 2 is used, and the second functional unit group. It has an inspection mode for performing a series of inspection operations.

According to such a configuration, it is possible to improve the inspection efficiency of the second functional unit group of the cover side assembly 60 as compared with the case where the second microcomputer 20 has only the normal use mode as the operation mode. .. That is, if the second microcomputer 20 has only the normal use mode, in the inspection process of the second functional unit group, each functional unit of the second functional unit group is individually driven by using the remote controller 11 or the like. Therefore, it is difficult to improve the inspection efficiency. On the other hand, since the second microcomputer 20 has an inspection mode for performing the inspection, the inspection signal 63 is transmitted once to the cover side assembly 60, so that the second functional unit group can be set. It can be operated automatically, and efficient inspection can be performed.

Further, in the sanitary cleaning device 2 according to the present embodiment, the second functional unit group includes the remote controller receiving unit 19, and the second microcomputer 20 receives the inspection signal 63 transmitted from the external remote controller 62 by the remote controller receiving unit 19. The inspection mode is executed when the signal is received.

According to such a configuration, it is possible to instruct the second microcomputer 20 to shift to the inspection mode by operating an external device such as the external remote controller 62. As a result, it is possible to inspect whether or not each functional unit of the second functional unit group is normally driven by remote control in the manufacturing process of the sanitary cleaning device 2, so that the inspection efficiency can be improved.

Further, in the sanitary cleaning device 2 according to the present embodiment, the second functional unit group has a notification unit 65 for notifying the inspection result in the inspection mode. According to such a configuration, the inspection result obtained by the inspection in the inspection mode of the second microcomputer 20 can be notified to the operator by the notification unit 65, so that the operator can easily recognize the inspection result. It will be possible.

In particular, the sanitary cleaning device 2 according to the present embodiment has a display unit 17 provided on the case cover 5b as a notification unit 65. According to such a configuration, the operator can visually confirm whether or not each functional unit of the second functional unit group is functioning normally, so that the inspection result can be recognized accurately and easily. Can be done.

Further, the sanitary cleaning device 2 according to the present embodiment has a sound generating unit 18 provided on the case cover 5b as a notification unit 65. According to such a configuration, the operator can confirm by sound whether or not each functional unit of the second functional unit group is functioning normally, so that the cover side assembly 60 to be inspected can be used. The test result can be recognized even from a distant position. Therefore, the inspection result can be recognized accurately and easily, and the inspection efficiency can be improved.

Further, in the sanitary cleaning device 2 according to the present embodiment, the device main body 4 includes a power supply board 45 for supplying electric power to the first microcomputer 10 and the second microcomputer 20 on the case plate 5a side. That is, in the device main body 4, the power supply board 45 as the power supply unit is not provided on the case cover 5b side, but is provided only on the case plate 5a side.

According to such a configuration, since the power supply unit is not provided on the case cover 5b side, the casing 5 is downsized as compared with the configuration in which the power supply unit is provided on both the case plate 5a side and the case cover 5b side. Can be planned. When inspecting each functional part of the second functional part group, the cover side assembly 60 and the plate side assembly 70 are not combined by using the external power supply 61 for inspection, that is, the case plate 5a. The inspection can be performed without using the power supply unit on the side. In this way, according to the configuration in which the power supply unit is integrated on the case plate 5a side, it is possible to prevent the equipment configuration required only in the inspection process of the second functional unit group from remaining in the final product, and the equipment in the final product. The size of the main body 4 can be reduced.

Further, in the sanitary cleaning device 2 according to the present embodiment, the second functional unit group includes a human body detection sensor 12, a seating detection sensor 13, a toilet seat thermistor 16, a display unit 17, a sound generating unit 18, a remote control receiving unit 19, and an electric motor. It consists of an opening / closing unit 50.

According to such a configuration, each functional unit of the second functional unit group provided on the case cover 5b side becomes a functional unit that can be inspected relatively easily. That is, sensors such as the human body detection sensor 12 can be inspected based on the signals returned from each sensor to the second microcomputer 20, and the display unit 17 and the electric opening / closing unit 50 visually recognize the display mode or operation. The inspection can be performed by checking the sound, and the sound generating unit 18 can be inspected by checking the sound.

In this way, by configuring the second functional unit group with functional units that are relatively easy to inspect, for example, a plurality of functional units can be inspected at once, and inspection efficiency can be improved. .. That is, the inspection of the second functional unit group can be easily performed in a relatively short time by using the second microcomputer 20, and the efficient inspection can be performed.

It is not limited to the configuration. In the inspection in the inspection mode, a receiving unit dedicated to the inspection for receiving the inspection signal 63 may be provided separately from the remote control receiving unit 19. However, from the viewpoint of making the device compact and reducing costs, it is preferable that the remote controller receiver 19 is also used as the receiver for the inspection signal 63.

Further, in the above-described embodiment, the external remote controller 62 dedicated to the inspection is used in the inspection in the inspection mode, but the remote controller 11 may be used instead of the external remote controller 62. That is, the remote controller 11 may be configured as a remote controller for transmitting the inspection signal 63 to the remote controller receiving unit 19.

Further, in the above-described embodiment, the external power supply 61 is used as a configuration for supplying electric power to the second microcomputer 20 in the inspection in the inspection mode, but in the cover side assembly 60, the second microcomputer 20 is used. It may be configured to provide a power supply device for supplying electric power. However, from the viewpoint of miniaturization of the device main body 4, it is preferable that the power supply unit is integrated on the case plate 5a side and the external power supply 61 is used in the inspection in the inspection mode as in the above-described embodiment.
