Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention relates to a structure of an infrared transmitting section of a remote controller in a bubble generating bath.

(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 channel. 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 of the control unit can be performed by an operation panel unit provided on a bathroom side wall or a bathtub body.

(C) Problems to be Solved by the Invention However, in the case of the above-mentioned operation panel section, since the operation panel section is fixedly attached to a bathroom side wall or a bathtub body,
When operating the operation panel unit, there is a trouble that the bather must reach a position where his hand can reach the operation panel unit, and there is a problem that the operation cannot be performed in a relaxed bathing posture.

Therefore, it is conceivable to remotely control the control unit using a remote controller that uses infrared light as a carrier.However, if infrared light can be transmitted only in the forward direction in the same direction as the axis of the remote controller, signal transmission by infrared light will be reliable. May not be done.

That is, when the remote controller is operated in the bathing posture as shown in FIG. 12, the remote controller is set in the upright position so that the bather can easily perform the switch operation and the like of the remote controller. However, if infrared rays can be transmitted in the same direction as above, there is a problem that the infrared receiving section provided at the edge of the bathtub body or the like cannot reliably receive signals.

Also, when operating the remote controller in a state where it is housed in a controller case or the like provided on a bathroom side wall or the like, even though the infrared receiver is located diagonally below the remote controller, the remote controller does not operate. There is a problem in that infrared rays are transmitted upward and signal transmission is not performed.

(D) Means for Solving the Problems In the present invention, a bath water circulation channel is interposed between the bathtub body and the circulation pump, and an air intake unit is connected to the bathwater circulation channel to connect the bathtub with the bathtub. In a bubble-generating bath tub that can blow out a bath containing air bubbles into the body, an infrared transmitter is provided at one end of a portable remote controller, and a circulating pump is used with the infrared light transmitted from the transmitter as a carrier. And a signal transmission to a control unit for controlling the infrared transmission unit, a front transmission light emitting body for transmitting infrared light forward, and a side transmission light emitting body for transmitting infrared light to the side.

When the user operates the remote controller with his / her hand, the signal is transmitted mainly by infrared rays transmitted from the front transmitting illuminant, and the operation is performed with the remote controller housed in a controller case or the like provided on the side wall of the bathroom. When the user operates the mobile phone in a state of being placed on the edge of the bathtub main body, the signal is transmitted mainly by infrared rays transmitted from the side transmitting light emitting body.

At this time, a certain angle is provided on the back side of the remote controller between the axis of the forward transmission light emitter and the axis of the remote controller, and the light emitter is inclined. Even when the remote controller is in the upright state so that the switch operation and the like can be easily performed, it is possible to reliably transmit the signal to the infrared receiving unit provided at the edge of the bathtub body or the like.

Also, a certain angle is provided between the axis of the side transmitting light emitter and a horizontal line orthogonal to the axis of the remote controller on the front side and below the remote controller, and the light emitter is inclined. Even when the remote controller is operated while housed in a controller case or the like provided on a bathroom side wall or the like, even though the infrared receiver is positioned obliquely below the remote controller, the signal of the infrared receiver is not required. Transmission can be performed reliably.

In this way, the bather takes a bath while holding the remote controller in his hand, operates the remote controller with the bathing posture relaxed, controls the circulating pump through the control unit, and bathes with air bubbles. It is possible to adjust the amount of squirt according to the user's preference, and also to operate the device without holding the hand, so that the user can easily operate the remote controller according to his preference.
