Description

The present invention relates to a method for assembling a case of a remote controller of a bubble generating bathtub.

(B) Conventional technology Conventionally, as an embodiment of a bubble generating bath, a bath hot water circulation channel is interposed between a bathtub body and a circulation pump, and an air intake unit is connected to the bath hot water circulation flow passage. In some cases, hot water mixed with air bubbles can be ejected into the bathtub body, and the number of rotations of the hot water mixed with air bubbles can be adjusted by controlling the rotation speed of a circulation pump by a control unit.

The operation such as the adjustment of the amount of spout of the bath water can be performed by an operation panel unit fixedly mounted on the wall surface of the bathroom.

(C) Problems to be Solved by the Invention However, in the case of the above-mentioned operation panel, since the operation panel is mounted on the wall surface of the bathroom, a bather needs to touch the operation panel when operating the operation panel. However, there is a problem that it is necessary to approach the position so that the operation cannot be performed in a relaxed bathing posture.

Further, when the operation panel section is mounted on the wall surface of the bathroom, a seat for mounting the operation panel section must be provided on the wall surface, and there is a problem that workability is poor.

(D) Means for Solving the Problems Therefore, in the present invention, a case of a remote controller in which each driving unit of the bubble generating bath can be operated via a control unit is assembled from an upper case, a lower case, and a partition. Inside, a method for assembling a case that forms a sealed electric circuit section chamber and a battery chamber that communicates with the atmosphere, wherein before bonding the peripheral end surfaces of the upper case and the lower case, an air vent hole is formed in the partition. When the two cases are adhered, the electric circuit section chamber and the battery chamber are communicated through the air vent hole, and after the two cases are adhered, a plug is attached to the air vent hole from the battery chamber, and the electric power is removed. It is an object of the present invention to provide a method for assembling a case of a remote controller of a bubble generating bathtub, wherein the circuit section chamber is closed.

Before bonding the peripheral end surfaces of the upper case and the lower case, an elastic rubber body is filled in a rubber body filling hole formed in the partition wall, and air is vented into both ends of the elastic rubber body. When the two tubes are glued together,
It is also characterized in that the electric circuit section chamber and the battery chamber communicate with each other through the air bleeding tube, and after the two cases are adhered, the air bleeding tube is pulled out of the elastic rubber body from the battery chamber to close the electric circuit section chamber.

Another feature is that the remote controller is assembled under a heating condition of about 50 ° C. so that the pressure in the electric circuit room becomes lower than the atmospheric pressure at room temperature.

In addition, after the air in the electric circuit room is sucked through the air vent hole or the air bleeding tube and the pressure in the electric circuit room is made lower than the atmospheric pressure at room temperature, the electric circuit room may be sealed. Has features.

(E) Function / Effect According to the present invention, the following function / effect is produced.

That is, in the present invention, each drive unit of the bubble generating bath is
Since the portable remote controller is operable, the bather takes a bath while holding the remote controller in his hand, and operates the remote controller in a relaxed bathing posture to operate the drive unit such as the circulating pump. It can be controlled via the control unit, and the amount of the hot water mixed with air bubbles can be adjusted as desired.

When assembling the case of such a remote controller, a hole for air vent was previously drilled in a partition wall for separating and forming the electric circuit section chamber and the battery chamber inside, and the peripheral end surfaces of the upper case and the lower case were bonded. At this time, since the electric circuit section chamber and the battery chamber communicate with each other through the air vent hole, the two cases can be easily and reliably bonded.

Subsequently, a plug is attached to the air vent hole from the battery chamber to close the electric circuit section chamber, thereby sealing the electric circuit section chamber and increasing the waterproofness of the electric circuit section disposed in the electric circuit section chamber. Can be secured.

At this time, under a heating condition of about 50 ° C., for example, a case of a remote controller is placed in a heating chamber, and after the air in the electrical circuit section is thermally expanded, a plug is attached to the air vent hole, and the electrical circuit section chamber is closed. By sealing, the pressure in the electric circuit section chamber can be kept lower than the atmospheric pressure at room temperature.

Also, the air in the electric circuit room may be sucked through the air vent hole so that the pressure in the electric circuit room is lower than the atmospheric pressure at room temperature.

In this way, when the remote controller is floated in a bath with a normal temperature of 38 to 42 ° C, or when hot water is applied to the remote controller, the case of the remote controller slightly expands thermally. Since the interior of the electric circuit section is set to a negative pressure at room temperature, the expansion of the air in the electric circuit section chamber can be suppressed, and the deformation of the case due to the air expansion can be prevented.

In addition, an elastic rubber body is filled in a rubber body filling hole formed in the partition wall, and a narrow tube for air vent opening at both ends is penetrated into the elastic rubber body, and the upper case and the lower case are separated. When the peripheral end surfaces are adhered, the two cases can be easily and reliably adhered to each other even if the electric circuit section chamber and the battery chamber communicate with each other through the air vent thin tube.

Subsequently, by pulling out the air bleeding tube from the battery chamber and restoring the elastic rubber body, it is possible to seal the electric circuit section chamber and ensure the waterproofness of the electric circuit section disposed in the same electric circuit section chamber. it can.

At this time, the blockage of the electric circuit unit chamber is performed after the air in the electric circuit unit room is thermally expanded in the heating chamber, as in the case described above.
By sucking the air through the bleeding tube and keeping the interior of the electric circuit room at a negative pressure, expansion of the air in the electric circuit room can be suppressed, and the case can be prevented from being deformed due to air expansion.

(F) Example Hereinafter, an example of the present invention will be described with reference to the drawings.
