[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller for a bathroom having a watertight structure for operating the bathroom function from inside a bathtub or the like in a bathroom having a bathroom function such as a bubble generating mechanism.

[0002]

2. Description of the Related Art Conventionally, there is known a bubble-generating bath having a mechanism for generating bubbles by taking out hot water supplied from the bath to the outside of the bath, mixing it with air and injecting it into the bath for reflux. ing. In the bathroom provided with the bubble generating bath, the generation state of bubbles in the bubble generating bath by transmitting an infrared signal to the main control device provided on the wall of the bathroom,
A remote controller is used that is capable of controlling functions such as the jetting direction and the strength of the jetted water flow. Such a remote controller generally has a high humidity in the bathroom and has a watertight structure so that it can be operated from the bathtub.

An example of the remote controller having the watertight structure is disclosed in Japanese Utility Model Laid-Open No. 3-98847. The remote controller described in the above publication is composed of a case body and a lid body that are vertically divided by a flat rectangular parallelepiped outer periphery, and a light emitting diode and the operation panel of the operation panel are provided in a case having an operation panel on the outer surface. A control device that causes a light emitting diode to emit light by an operation and a battery chamber that houses a battery that supplies power to the control device are watertightly housed. The light emitting diode is disposed on the side surface of the case so as to face an infrared transmitting window provided between the case body and the lid body, and is capable of projecting infrared rays to the outside of the case.

In the remote controller described in the above publication, the control device is housed on the back surface of the operation panel inside the case body, and a plurality of operation switches operated from the operation panel and input from the operation switch are input. And a CPU that outputs a predetermined serial code signal to the light emitting diode according to a signal. Further, the battery chamber is separated from a compartment in which the control device is accommodated by a partition wall and is defined independently, and communicates with an opening provided on a side surface of the lid. Two AA dry batteries are inserted into the battery chamber through the opening, and the opening is water-tightly closed by a battery chamber lid having packing on the outer circumference. ing.

The light emitting diode and the terminals provided on the battery chamber and the battery chamber lid are connected to the printed circuit board of the control device by conducting wires covered with flexible tubes.

In the remote controller having the above structure, the case body, the lid, and the infrared transmitting window are integrally formed by engaging each other with a sealing agent, and the battery chamber lid is provided with the packing through the packing. The watertightness of the case is ensured by being screwed onto the lid.
Further, the remote controller is provided with buoyancy by the air sealed in the case and can be floated in the bath water supplied in the bathtub.

However, since the case is heated to about 40 to 50 ° C. by the bath water when taking a bath, the air sealed in the space in the case expands, and when it is not used, it is cooled to about room temperature. Since the air contracts, the case is deformed by repeated expansion and contraction of the air during long-term use, and the watertightness between the case body and the lid tends to be reduced. is there.
When the watertightness is reduced, water may enter the inside of the case and cause malfunction of the control device.Therefore, each electric function necessary for operating the remote controller such as the light emitting diode, the control device, and the terminal in the case. It is necessary to waterproof the parts.

Therefore, in the remote controller described in the above publication, the electrically exposed portion of the control device and the conductor wire covered with the flexible tube connected to the control device is made of urethane resin or epoxy resin in the case body. Waterproofing is performed by filling a potting liquid made of a thermosetting resin and embedding it in a resin layer formed by solidifying. According to the description of the publication, by doing so, even if the watertightness of the case is reduced, the electrically exposed portion of the conductor covered with the transmission control means and the flexible tube is formed from the potting liquid. Since it is covered with the resin layer, watertightness is surely ensured, and since a gap is secured between the portion covered with the resin layer and the lid body, buoyancy is generated by the air sealed in the gap. It is supposed to be obtained.

However, in the remote controller described in the above publication, while the light emitting diode and the control device are housed in the case body, one of the terminals connected to the battery is a battery screwed to the lid side. Since the potting liquid is filled in the chamber lid, the terminals provided in the battery chamber lid are connected to the control device, and the infrared transmitting window is connected to the case body and the lid. It can be performed only after it is engaged so as to be sandwiched between and. That is, the potting liquid is filled with the case body closed by the lid.

For this reason, it is difficult to confirm the coating state of the electrically exposed portion with the potting liquid, and there is a fear that sufficient watertightness may not be obtained. Further, if the potting solution is excessively filled to ensure sufficient water tightness, the potting solution is opaque and thus the light emitting diode is covered so that the infrared signal cannot be transmitted or flows to an unnecessary portion. Then, the space between the lid and the lid is lost and the buoyancy is reduced.
