Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an infrared receiving sensor structure for remote control in a bubble-generating bathtub.

(B) Conventional technology Conventionally, as described in Japanese Patent Application Laid-Open No. 59-135058, a bubble-generating bathtub has a bath water suction system between the bathtub body and a circulation pump installed outside the bathtub body. A bath water circulation flow path consisting of a vibrator and a forced bath water supply pipe is provided, and an air intake part is provided in the middle of the forced bath water flow pipe, and the bath water is circulated through the bath water circulation flow path by the operation of the circulation pump. Some bathtubs are designed to eject water from a nozzle into the bathtub body, and simultaneously mix it with air sucked in from an air intake to eject bathwater mixed with bubbles.

In order to carry out such operations, it is conceivable that the operation is performed by emitting infrared rays from a remote controller, but it is necessary to make effective use of space and to integrate a receiving sensor that receives infrared rays from the remote controller with the operation panel. It is conceivable to provide it at the edge of the upper bathtub body.

(c) Problems to be Solved by the Invention However, if the infrared receiving sensor is installed flat on the edge of the bathtub body, the edge of the bathtub body will interfere even if the bather operates the remote controller from inside the bathtub. Therefore, the infrared rays may not reach the receiving sensor.

(d) Means for Solving the Problems In the present invention, a bath water circulation channel consisting of a bath water suction vibrator and a bath water forced feed vibrator is provided between a bathtub body and a circulation pump installed outside the bathtub body. A plurality of terminal ends of the bath water forcing vibrator are opened into the bathtub body to serve as jet nozzles, and an air intake part is connected to the bath water forcing vibration to communicate with the bath water forcing vibrator, so that air bubbles are mixed from the jet nozzle. In the bubble-generating bath tff configured to be able to jet bath water into the bathtub body, the bubble-generating jet is configured to be operated by emitting infrared rays from a remote controller, and an infrared receiving sensor receives infrared rays from the remote controller. The present invention aims to provide an infrared receiving sensor structure for remote control in a bubble-generating bathtub, which is formed into a hemispherical shape and is attached to the edge of the bathtub body in a downwardly sloping manner toward the inside of the bathtub. .

(e) Functions and Effects In this invention, when taking a bath in a bubble-generating bathtub, a jet of bubbles is obtained by operating an operation panel provided at the edge of the bathtub body, but on the other hand, a remote controller is used. When operating the bathtub while immersed in the bathtub, the remote controller emits infrared rays from the infrared irradiating part, and the infrared receiving sensor installed on the edge of the bathtub body receives the infrared rays to perform remote control. However, since the infrared receiving sensor is hemispherical and is installed in a downward-sloping manner toward the inside of the bathtub, even if the infrared emitting part of the remote controller is located in most places inside the bathtub, the infrared rays can be reliably detected. It has the effect of allowing accurate remote control.
