BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body local cleaning apparatus having a shower unit for spraying a cleaning liquid onto a local area of a user to clean the local area.

[0002]

2. Description of the Related Art A human body local cleaning device of this type has a base,
The seat includes a toilet seat that is mounted on the base and on which a user sits, a shower unit that is mounted on the base and sprays cleaning water onto the user's local area to wash the local area, and a controller that controls the operation of the shower unit. The human body local cleaning device is increasingly required to be compact in size. In particular, with the widespread use in ordinary households, there has been an increasing demand for downsizing of the entire human body local cleaning device that can be easily installed even in a small toilet room such as an apartment or a one-room apartment. In addition, since the human body local cleaning device is installed in the toilet room for a long period of time, water, urine, and moisture may enter the inside of the device. The mounted parts require moisture resistance.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 07-321472, the entire control board is put in an open type resin control case for the purpose of preventing the humidity of the control board on which the mounting components are mounted, and urethane, epoxy, etc. are used. The structure has been adopted in which mounted components such as electronic parts or electric parts mounted on the control board are covered with the control board by using the elastic sealant described above to enclose them. With this, it is possible to improve the moisture resistance of mounted components such as electronic components or electric components mounted in the control device, and it is advantageous for extending the life.

[0004]

In the above-mentioned human body local cleaning apparatus, the lead wires of the mounting parts such as electronic parts and electric parts mounted on the control board are exposed from the control board, and accordingly, Space was required, and there was a limit to the downsizing of the control case.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to make the control case of the control device compact, and to further enhance the moisture-proof property of the conductive member to intrude moisture, urine, or moisture. It is an object of the present invention to provide a human body local cleaning device that is more advantageous for suppressing the above-mentioned problems.

SUMMARY OF THE INVENTION A human body local cleaning apparatus according to the present invention comprises a base portion, a toilet seat mounted on the base portion on which a user sits, and a cleaning liquid jetted to the user's local portion mounted on the base portion to clean the local portion. A human body part cleaning device comprising a shower part for cleaning and a control device for controlling the operation of the shower part,
The control device includes a control case that has a storage chamber inside and is made of resin as a base material, a mounting component made of an electronic component or an electrical component that is stored in the storage chamber of the control case, and a wall of the control case that is formed of a conductive material. A conductive member that is embedded in the part and that has one end that is electrically connected to the mounted component and that has the other end that is electrically connected to the connector part or another mounted component in the housing chamber; and the conductive member and the end surface of the control case. And a sealant applied to the boundary of the container to enhance the moisture-proof property of the storage chamber.

According to the human body local cleaning apparatus of the present invention,
Since the conductive member that is electrically connected to the mounted component in the control case housing is embedded in the wall thickness of the resin-based control case wall, the conductive member is arranged in the control case. Space is unnecessary or reduced. Furthermore, since the conductive member electrically connected to the mounted components in the housing chamber is embedded in the wall thickness of the resin-based control case wall, the moisture resistance of the conductive member can be further improved. It is even more advantageous to prevent breakdown due to moisture, urine, and moisture.

By the way, a decompression phenomenon may occur in the accommodating chamber due to repeated heat generation by the mounted components arranged in the accommodating chamber of the control case, repeated stoppage of heat generation, and the like. In this case, a respiratory action in the control case may occur with the decompression. In this case, when the human body local cleaning device is used for a long period of time, even if the conductive member is hidden and buried in the wall thickness of the control case, the control is performed from the boundary between the conductive member and the control case. The water outside the case is very small,
There is a risk that it will gradually penetrate into the storage chamber of the control case.
Therefore, by applying a moisture-proof sealant to the boundary between the conductive member and the end surface of the control case, water permeation from the boundary between the conductive member and the control case into the storage chamber is suppressed. A resin can be used as the sealing agent, and examples thereof include a silicone resin and an epoxy resin.

According to the human body local cleaning device of the present invention,
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 such as a thermoplastic resin or a thermosetting resin can be adopted, and polybutylene terephthalate, polyamide, polypropylene, polycarbonate, polyacetal, AB can be used.
Examples include S and PMMA. 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, and examples thereof include phosphor bronze, copper, aluminum, steel, stainless steel, titanium, gold, and alloys thereof. According to the human body local area cleaning apparatus of the present invention, the conductive member that is electrically connected to the mounted component, which is an electronic component or an electrical component, accommodated in the accommodation chamber of the control case is buried in the wall of the control case. Sex is secured. In order to enhance the moisture resistance, the conductive member may be embedded in the wall thickness of the control case in a completely concealed state, or while the conductive member is embedded in the control case wall, The end may be exposed on the outer wall surface of the control case. According to the human body local area cleaning apparatus of the present invention, at least one of the following methods can be adopted.

The conductive member may be one that electrically connects the mounted component inside the accommodation chamber of the control case and the connector, or one that electrically connects the mounted components inside the accommodation chamber of the control case. In the latter case, the mounting component mounted on the mounting surface of the control board disposed in the control chamber housing and the mounting component mounted on the heat dissipation plate provided in the control case are electrically connected. But good. Alternatively, the mounting components mounted on the mounting surface of the control board arranged in the accommodation chamber of the control case may be electrically connected to each other.

At least a part of the conductive member may adopt a system having an embedded conductive portion embedded in the wall of the control case and an exposed conductive portion exposed from the control case. In this case, it is advantageous for the Joule heat generated by the conduction to the conductive member to escape from the exposed conductive portion to the outside of the case. Further, it is easy to electrically connect the terminal of the mounted component in the accommodation chamber to the exposed conductive portion of the conductive member.

At least a part of the exposed conductive portion 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, a C shape and the like. In this case, by arranging the lead terminals of the mounting components (including the mounting components mounted on the heat sink) housed in the housing chamber in the central space forming the concave shape of the tip of the exposed conductive portion, , It becomes easy to electrically connect the both. It is preferable to solder at the time of connection.

As a mounting component composed of an electronic component or an electric component, a system mounted on a mounting surface of a control board arranged in a storage chamber of a control case can be adopted. In this case, the plurality of control boards are arranged in the accommodating chamber of the control case so as to be stacked at a predetermined interval. As the control board, for example, the size may be substantially the same as the inner size of the accommodation chamber of the control case, or may be slightly smaller. The control board may employ a method having holes such as through holes electrically connected to the mounted components mounted on the control board. The hole means a conductive member having a hole to be soldered while the mating conductive member is inserted.

At least a part of the conductive member has a buried conductive portion buried in the wall of the control case and an exposed conductive portion 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 such as a through hole of the control board and soldered. As a result, the conductive member embedded in the wall of the control case can be electrically connected to the mounted component of the control board through the hole such as the through hole of the control board.

The control case may adopt a system having a storage recess for storing the sealant at the root of the conductive member where the conductive member is exposed from the control case. 1
It is preferable that many conductive members are exposed in one storage recess. In this case, a large number of conductive members can be collectively sealed by injecting a sealing agent into one storage recess and solidifying it, which is advantageous in enhancing moisture resistance. It is preferable that the bottom surface of the storage recess be inclined so as to become deeper as it goes away from the storage chamber. It is possible to prevent the sealant stored in the storage recess from flowing out to the accommodation chamber side.

The mounted component is mounted on a control board arranged in the accommodation chamber of the control case, and the control board has a notch facing the storage recess and enhancing the injection of the sealant into the storage recess. The existing method can be adopted. The notch improves the injection property of the sealant into the storage recess.

As the control case, it is possible to adopt a system provided with a heat dissipation plate made of a material having heat dissipation properties. In this case, the heat radiating plate may employ a method having an embedded portion integrally insert-molded in the control case and an exposed portion that is exposed from the control case and to which the heating element is attached. Since the heat sink is integrally embedded and attached to the control case as described above, the fixture for attaching the heat sink to the control case can be eliminated. Further, since the exposed portion of the heat dissipation plate is not buried in the control case but is exposed from the control case, heat dissipation to the outside of the storage chamber is secured. In particular, it is advantageous to dissipate the heat generated by the heat-generating element if the heat-generating element that generates a large amount of heat is attached to the exposed portion of the heat dissipation plate. In this case, it is preferable that the mounted component that generates less heat is attached to the control board and the mounted component that generates more heat is attached to the heat dissipation plate.

The control case may be provided with an opening, and the exposed part of the heat dissipation plate may close the opening of the control case. In this case, since the exposed portion of the heat dissipation plate closes the opening of the control case, that is, the storage chamber, it is advantageous to use the heat dissipation plate to seal or nearly seal the storage chamber of the control case. The moisture-proof property for the storage chamber can be enhanced. Further, 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 ensuring the volume of the control case, which can contribute to cost reduction. The shape of the heat dissipation plate is not particularly limited, and at least one of an L-shaped section, a U-shaped section, an I-shaped section, a C-shaped section and the like can be adopted. It is preferable that the material of the heat radiation plate has a good heat radiation property, and in general, examples of the metal that can be used include metals such as aluminum, steel, stainless steel, copper, titanium and alloys thereof.
