In the left-right direction X, one side is the one side X1, and the other side is the other side X2. The direction along the up-down direction of the toilet device 1 is defined as the up-down direction Z of the substrate component 9.

[0017] As shown in FIG. 3, the substrate component 9 is attached to the side surface of the front side Y1 of the cleaning tank 71 in a state where the bottom 92 (see FIG. 5) of the substrate case 91 is arranged along the side surface of the front side Y1 of the cleaning tank 71.

[0018] As shown in FIGS. 4 and 5, the substrate component 9 includes a substrate case 91, a substrate 96 arranged in the substrate case 91, and a potting material 97 (see FIG. 5) filled in the substrate case 91.

[0019] The substrate case 91 is formed in a case shape that opens toward the front side Y1 of the toilet device 1. The substrate case 91 houses a substrate 96 on which an electronic component 961 and a connector connection part 962 are mounted. The substrate case 91 includes a bottom 92, a wall part main body 93 (bottom side wall part), a step part 94, and a guard part 95.

[0020] <0者には、本発明の一部又は全部を、電子回路を用いて実現することができる。 As shown in FIG. 5, the bottom 92 is arranged along the surface of the front side Y1 of the cleaning tank 71. The substrate case 91 is attached to the side surface of the front side Y1 of the cleaning tank 71 in a state where the bottom 92 is arranged along the side surface of the front side Y1 of the cleaning tank 71.

[0021] The bottom 92 has a bottom plate 921 whose shape is rectangular when viewed from the front side Y1, and a substrate support protrusion 922 that protrudes from the bottom plate 921 toward the front side Y1. The bottom plate 921 extends in the up-down direction Z and the left-right direction X. The substrate 96 is attached to the bottom 92 in a state of being supported by the substrate support protrusion 922.

[0022] On the substrate 96, a plurality of electronic components 961 and connector connection parts 962 are provided. On the substrate 96, electronic components 961, connector connection parts 962, and other electronic components that protrude to a position higher than the height of the substrate case 91 are mounted.

[0023] The wall body 93 is formed in a wall shape that rises from the peripheral edge of the bottom 92 to the front side Y1. The wall body 93 is provided in a wall shape over the entire circumferential direction along the peripheral edge of the bottom 92.

[0024] The stepped portion 94 is provided at the end on the front side Y1 of the wall body 93 (the end on the side opposite to the bottom 92 in the wall body 93). The stepped portion 94 is provided over the entire circumferential direction of the wall body 93. The stepped portion 94 has a middle portion 941 (a side extending portion), a stepped portion side wall portion 942, and a plurality of reinforcing plates 943.

[0025] The middle portion 941 extends from the end on the front side Y1 of the wall body 93 (the end on the side opposite to the bottom 92 in the wall body 93) to the outside side of the wall body 93 with a predetermined width substantially parallel to the bottom 92. The middle portion 941 is formed over the entire circumferential direction of the end of the wall body 93 of the substrate case 91.

[0026] The stepped portion side wall portion 942 is formed in a wall shape that rises from the outer end of the middle portion 941 to the front side Y1. The stepped portion side wall portion 942 is provided in a wall shape over the entire circumferential direction along the outer peripheral edge of the middle portion 941.

[0027] The plurality of reinforcing plates 943 reinforce the stepped portion 94. The plurality of reinforcing plates 943 are formed in a plate shape connecting the middle portion 941 and the stepped portion side wall portion 942. The plurality of reinforcing plates 943 are provided at intervals in the circumferential direction.

[0028] In this embodiment, as shown in Figure 4, the stepped portion 94 includes an upper stepped portion 94a provided at the upper end of the substrate case 91, a lower stepped portion 94b provided at the lower end of the substrate case 91, a one-side stepped portion 94c provided on one side X1 in the left-right direction X, and a other-side stepped portion 94d provided on the other side X2 in the left-right direction X. The width of the middle portion 941 of the one-side stepped portion 94c and the other-side stepped portion 94d is formed to be larger than the width of the middle portion 941 of the upper stepped portion 94a and the lower stepped portion 94b.

[0029] In the circuit board case 91, a connector connection portion 962 is located inside the stepped portion 94c on one side, adjacent to the stepped portion 94c. The stepped portion 94c on one side has a middle portion 941 and a stepped portion side wall portion 942. The middle portion 941 extends from the front end Y1 of the wall body 93 (the end opposite to the bottom portion 92 of the wall body 93) to the outside of the wall body 93, approximately parallel to the bottom portion 92, with a predetermined width. The stepped portion side wall portion 942 rises from the outer end of the middle portion 941.

[0030] As a result, the stepped portion 94c on one side is provided with a middle portion 941 and a side wall portion 942 of the stepped portion, so when attaching or detaching the connector 11, the worker can position their fingers in the space S in front of the middle portion 941 Y1. Therefore, since the fingers do not come into contact with the side wall portion 942 of the stepped portion, the attachment and detachment of the connector 11 is easy.

[0031] As shown in Figures 4 and 6, the guard portion 95 is provided at the lower end of the substrate case 91. The guard portion 95 is formed to protrude outward from the lower part of the substrate case 91. The guard portion 95 protects harnesses (wiring), etc., from coming into contact with, for example, the head 811 (metal part) of a screw 81, which is a component of the lifting device 8. The guard portion 95 is provided, for example, above the head 811 of a screw 81 located at the top of the lifting device 8.

[0032] The guard portion 95 has a lateral projection plate 951 that protrudes laterally from the front side Y1, and a downward projection plate 952 that protrudes downward from the tip of the lateral projection plate 951. The guard portion 95 protects the upper and front sides of the head 811 (metal part) of the screw 81, which is a component of the lifting device 8, thereby preventing harnesses (wiring) and the like from coming into contact with the head 811 (metal part) of the screw 81.

[0033] As shown in Figure 5, the potting material 97 is filled from the bottom 92 of the substrate case 91 up to the height of the wall body 93. The potting material 97, being a resin material, is filled in a solution state and hardens to fix the substrate 96 to the substrate case 91. The potting material 97 fills the area from the bottom 92 of the substrate case 91 up to the height of the wall body 93, and fixes the substrate 96, electronic components 961 and connector connection part 962. The potting material 97 is not filled in the stepped portion 94.

[0034] In the above-described circuit board component 9, a stepped portion 94 is provided at the front end Y1 of the wall body 93 of the circuit board case 91. The middle portion 941 of the stepped portion 94 provides space S for the worker's fingers to be positioned when attaching or detaching the connector 11 to the connector connection portion 962. Therefore, the connector 11 can be easily attached to and detached from the connector connection portion 962.

[0035] Here, in order to facilitate the attachment and detachment of the connector 11 to the connector connection portion 962, it is conceivable to create a space to the side of the connector connection portion 962 by moving the position of the wall body 93 outward without providing the stepped portion 94. In this case, if the wall body 93 is moved outward, the area of ​​the bottom portion 92 of the substrate case 91 will increase by the amount that the position of the wall body 93 has been moved outward. This will increase the amount of potting material 97 used. In contrast, in this disclosure, by providing the stepped portion 94 without moving the wall body 93 outward, it is not necessary to fill the stepped portion 94 with potting material 97. This allows the amount of potting material 97 used to be suppressed while making it easy to attach and detach the connector 11 to the connector connection portion 962.

[0036] The toilet device 1 of this embodiment, as described above, provides the following effects.

[0037] The toilet device 1 of this embodiment comprises a circuit board 96 on which electronic components 961 and a connector connection portion 962 are provided, and a circuit board case 91 that houses the circuit board 96. The circuit board case 91 has a bottom portion 92 on which the circuit board 96 is placed, a wall portion body 93 rising from the edge of the bottom portion 92, and a stepped portion 94 provided at the end of the wall portion body 93 opposite to the bottom portion 92. The stepped portion 94 has a middle portion 941 extending outward from the end of the bottom side wall portion 93 opposite to the bottom portion 92, and a stepped portion side wall portion 942 rising from the outer end of the middle portion 941. By providing the stepped portion 94, the amount of potting material 97 used can be reduced, and the connector 11 can be easily attached to and detached from the connector connection portion 962.

[0038] In this embodiment, the stepped portion 94 is provided with multiple reinforcing plates 943. This allows the stepped portion 94 to be reinforced by the multiple reinforcing plates 943, thereby improving its strength.

[0039] In this embodiment, the substrate case 91 is attached to the side of the cleaning tank 71 with its bottom portion 92 positioned along the side of the cleaning tank 71. This allows the connector 11 to be easily attached to and detached from the connector connection portion 962 while suppressing the amount of potting material 97 used by the stepped portion 94 when the substrate case 91 is mounted vertically along the side of the cleaning tank 71.

[0040] In this embodiment, the presence of a guard portion 95 in the substrate case 91 prevents the harness (wiring) and the like from coming into contact with the head 811 (metal part) of the screw 81, which is a component of the lifting device 8.

[0041] Preferred embodiments of the present disclosure have been described above. The present disclosure is not limited to the embodiments described above and can be modified as appropriate.

[0042] In the above embodiment, the stepped portion 94 was provided over the entire periphery of the substrate case 91. However, it is not limited to this. The stepped portion 94 may be provided on a part of the edge of the substrate case 91.

[0043] In the above embodiment, the substrate case 91 was positioned vertically along the side of the cleaning tank 71. However, it is not limited to this. The substrate case 91 may also be positioned horizontally. [Explanation of symbols]
