SUMMARY OF THE INVENTION A human body local cleaning apparatus according to the present invention comprises a base, a toilet seat mounted on the base, on which a user sits, and a cleaning liquid, which is mounted on the base and jets a cleaning liquid to the user's local area, to clean the local area. In a human body local cleaning device including a shower unit for cleaning and a control device for controlling the operation of the shower unit,
The control device has a control case having a housing chamber formed therein and a resin as a base material, a mounting component made of an electronic component or an electric component housed in the housing chamber of the control case, and a control case formed of a conductive material. A conductive member having one end buried in the wall portion and electrically connected to the mounted component and having the other end electrically connected to another mounted component in the connector portion or the accommodation room. Things.

[0007] The control case is made of resin as a base material and has high electrical insulation. The resin is not particularly limited, and a known resin can be employed, and examples thereof include polyamide, polybutylene terephthalate, polypropylene, polycarbonate, ABS, PMMA, POM, and PBT. Examples of the conductive member embedded in the control case include a conductive wire, a printed circuit, and a lead wire. The material of the conductive member may be any conductive material, such as phosphor bronze,
Examples thereof include copper, aluminum, steel, stainless steel, titanium, gold, and alloys thereof. According to the human body local cleaning apparatus according to the present invention, the conductive member that is electrically connected to the electronic component or the mounted component including the electrical component housed in the housing chamber of the control case includes:
Since it is buried in the wall of the control case, moisture resistance is ensured. In order to enhance the moisture resistance, the conductive member may be buried in a completely concealed state within the thickness of the wall of the control case, or while the conductive member is buried in the wall of the control case,
The end of the conductive member may be exposed on the outer wall surface of the control case. According to the human body local cleaning device of the present invention, at least one of the following methods can be adopted.

[0008] At least a part of the conductive member may employ a system having a buried conductive portion buried in a wall of the control case and an exposed conductive portion exposed from the control case. In this case, it is advantageous to release Joule heat generated by conduction to the conductive member from the exposed conductive portion to the outside of the case. Further, it is easy to electrically connect the terminals of the mounted components in the accommodation chamber to the exposed conductive portions of the conductive members.

The leading end of the exposed conductive portion of at least a part of the conductive member may have a concave shape having a central space. Examples of the concave shape having the central space include a U shape, a Y shape, and a C shape. In this case, the lead terminals of the mounted components (including the mounted components mounted on the heat sink) housed in the housing chamber may be arranged in the central space forming the concave shape at the end of the exposed conductive portion. It is easy to electrically connect the two. It is preferable to solder at the time of connection.

[0010] As a mounting component made of an electronic component or an electrical component, a system mounted on a control board disposed in a housing room of a control case can be adopted. In this case, a plurality of control boards can be arranged in the accommodation room of the control case so as to be stacked. The control board can adopt a system having a hole electrically connected to a mounted component mounted thereon. The hole means a conductive member having an insertion hole to be soldered in a state where the mating conductive member is inserted. In this case, at least a part of the conductive member has a buried conductive part buried in the wall of the control case and an exposed conductive part exposed from the control case. Then, it is possible to adopt a method in which the tip of the exposed conductive portion of the conductive member is inserted into a hole of the control board and soldered. Thus, the conductive member buried in the wall of the control case can be electrically connected to the mounted components of the control board through the holes of the control board.

As the control case, a system having a heat radiating plate formed of a material having heat radiating properties can be adopted. In this case, the heat radiating plate may adopt a method having a buried portion integrally formed with the control case by insert molding, and an exposed portion exposed from the control case and to which the heating element is attached. Since the heat sink is integrally buried and attached to the control case in this manner, a fixture for attaching the heat sink to the control case can be eliminated. In addition, since the exposed portion of the heat sink is not embedded in the control case but is exposed from the control case, heat radiation to the outside of the accommodation room is secured. In particular, if a heat generating element having a large amount of heat is attached to the exposed portion of the heat sink, it is advantageous to release heat generated by the heat generating element. In this case, it is preferable to mount a component having a small heat value among the mounted components to the control board, and to mount a component having a large heat value among the mounted components to the heat sink.

The control case is provided with an opening, and a system in which the exposed portion of the heat sink closes the opening of the control case can be adopted. In this case, since the exposed portion of the heat sink closes the opening of the control case, that is, the accommodation room, it is advantageous to make the accommodation room of the control case hermetically or almost hermetically utilizing the heat sink, It is possible to enhance the moisture resistance of the accommodation room. Furthermore, since the heat radiating plate is embedded in the control case, it is advantageous to reduce the amount of resin required for forming the control case while securing the volume of the control case, which can contribute to cost reduction. The shape of the heat sink is not particularly limited, and may be at least one of an L-shaped cross section, a U-shaped cross section, an I-shaped cross section, and a C-shaped cross section. The heat radiating plate is preferably made of a material having good heat radiating properties. In general, metals that can be employed include aluminum, steel, stainless steel, copper, titanium, and alloys thereof.

In the control case, the wall portion near the heat radiating plate can adopt a system having a positioning portion for positioning the heating element. This facilitates the mounting of the heating element. It is preferable that the heat radiating plate has a mounting portion for mounting the heating element. Examples of the attachment portion include at least one of a female screw, a male screw, and a concave-convex engagement.

The control case may be of a type including a connector portion provided on the outer wall surface side of the control case and electrically connected to a mating connector portion. The connector part has a connector housing part which is fitted with the mating connector part and is formed integrally with the control case, and adopts a method in which at least a part of the exposed conductive part of the conductive member is provided in the connector housing part. can do. In this case, it is possible to adopt a method in which the bottom surface of the housing portion of the connector portion is closer to the accommodation room side of the control case than the outer wall surface of the control case. This is advantageous in reducing the size of the entire control device.

It is possible to adopt a system in which a wall portion that can increase the distance connecting the adjacent lead terminals is formed integrally with the control case between the adjacent lead terminals of the heating element. In this case, the creepage distance between the adjacent lead terminals can be increased. This is advantageous for preventing discharge between the lead terminals of the heating element.

According to the present embodiment, as shown in FIGS. 11 and 12, the upper case 21 is integrally formed with a projection wall 69 which can function as a storage space forming means. The surface of the first control board 51 is positioned in contact with the projection wall 69 of the upper case 21. Projection wall 6
9, a storage space 69p having a shallow bottom surface is formed in the wall of the upper case 21. A sealing agent 6 made of resin is injected into the storage space 69p, solidified, and sealed. Thereby, the sealing property at the boundary between the upper case 21 and the first lead wire 3 embedded therein is enhanced, and the moisture proof property is enhanced.
The sealant 6 in the storage space 69p is prevented from flowing out of the storage space 69p by the projection wall 69, and the sealing property of the sealant 6 is maintained.

Further, according to the present embodiment, as shown in FIG. 13, the storage space 69 of the first control board 51 is provided.
A notch group 80 including a large number of notches 82 having a concave shape is formed at the p-side edge by retreating between adjacent through holes 51c in the direction of arrow S1. in this case,

Further, according to the present embodiment, as shown in FIG. 14, a small confirmation window 21i is formed in the upper case 21 near the seal groove. Since the presence or absence of the seal member 21p in the seal groove 21n can be visually recognized from the confirmation window 21i, it is possible to confirm that the seal member 21p has been left unattached, and in this sense, it is possible to enhance the moisture-proof property in the storage chamber 2x. Therefore, the confirmation window 21i can function as a seal member confirmation unit that confirms the presence or absence of the seal member 21p.

By the way, the pressure reduction phenomenon may occur in the accommodation room 2x due to the heat generated by the heating element 57 arranged in the accommodation room 2x of the control case 2 and the repeated stop of the heat generation. In this case, a respiratory action in the control case 2 may occur with the decompression. In this case, if the use period of the human body local cleaning device is long, the first lead wire 3 and the second lead wire 4 are concealed and embedded in the thickness of the upper case 21, but the first lead wire 3 and the second lead wire 4 are buried. Although the water outside the control case 2 is minute from the boundary between the upper case 21 and the second lead wire 4 and the boundary between the upper case 21, there is a possibility that the water permeates into the storage chamber 2 x of the control case 2. Therefore, as shown in FIG. 8, a small escape hole 26 t that connects the inside and the outside of the storage chamber 2 x is formed in the lower case 26. The escape hole 26t always suppresses the differential pressure between the inside and the outside of the accommodation room 2x, and thus suppresses the above-mentioned respiratory action, so that the inside of the accommodation room 2x extends from the boundary between the first lead wire 3, the second lead wire 4 and the upper case 21. It suppresses the penetration of moisture into water. Also in this sense, the moisture-proof property of the accommodation room 2x is ensured. As shown in FIG. 8, the escape hole 26t is shielded by a heat radiating plate 29, so that dust, moisture and the like do not enter the accommodation room 2x. The escape hole 26t may be formed in the upper case 21 or the heat sink 29.

According to the present embodiment, as a procedure for assembling the control case 2, the first control board 51 is attached to the upper case 21, the second control board 55 is further attached, and then the lower case is attached to the upper case 21. The case 26 can be assembled so as to be connected.

As described above, according to the present embodiment,
The first lead wire 3, which functions as a conductive member electrically connected to the mounting components 52, 56 of the control device 150,
Since the second lead wire 4 is buried in the thickness of the wall of the resin control case 2, a space for disposing the first lead wire 3 and the second lead wire 4 in the accommodation room 2x becomes unnecessary. This is advantageous in reducing the size of the control case 2 according to the control device 150.

Further, according to the present embodiment, as described above, the first lead wire 3 and the second lead wire 4 are embedded in the thickness of the control case 2 made of resin. , The moisture resistance of the second lead wire 4 can be further enhanced, moisture, urine, and moisture can be suppressed from entering the accommodation room 2x, which is further advantageous for suppressing failure caused by moisture, urine, and moisture. .

1, but may be buried in the lower case 26 instead of the upper case 21 and the lower case 2 and the lower case 2.
6 may be buried in both. The first in the accommodation room 2x
The control board 51 and the second control board 55 are stacked at a predetermined interval, but the present invention is not limited to this, and the number of control boards may be one, three, or more. Further, according to the above-described embodiment, the first lead wire 3 and the second lead wire 4 made of metal are embedded in the thickness of the upper case 21. However, the present invention is not limited to this, and the metal member is covered with the insulating film. The conductive member may be embedded in the thickness of the upper case 21 made of resin.

According to the human body local cleaning apparatus of the present invention, the conductive member electrically connected to the mounted components in the accommodation room of the control case is formed of a resin-based control case having a thick wall. Since the conductive member is buried in the control case, a space for disposing the conductive member in the control case is unnecessary or reduced, which is advantageous in reducing the size of the control case related to the control device. Further, since the conductive member electrically connected to the mounted components in the accommodation chamber is embedded in the wall thickness of the resin-based control case, the moisture resistance of the conductive member can be further improved, and It is even more advantageous for suppressing failure due to urination and moisture.

When the heat radiating plate for mounting the heat generating element is buried in the control case, a fixture for mounting the heat radiating plate to the control case can be eliminated. Further, since the exposed portion of the heat sink is not embedded in the control case but is exposed from the control case, heat radiation from the exposed portion of the heat sink to the outside of the accommodation room of the control case is ensured. In particular,
When a heating element having a large amount of heat is attached to the exposed portion of the heat radiating plate, it is advantageous to emit heat from the heating element.
