Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention relates to a display device for a bubble generating bathtub.

(B) Conventional technology Conventionally, as an embodiment of a bubble generating bathtub installed in a bathroom, a bathwater circulation channel including a water absorption pipe and a water supply pipe is interposed between a bathtub body and a circulation pump, The end of the water supply pipe was opened into the bathtub body to form a jet nozzle, and an air intake section was connected to the water supply pipe so as to be connected to the water supply pipe so that the bubbled bath water could be jetted into the bathtub main body from each jet nozzle. There is something.

An operation panel section is provided so that operations such as operation / stop of the bathtub and change of a hot-water jet state can be performed through the operation panel section.

(C) Problems to be Solved by the Invention However, in the above-mentioned conventional technology, since the function of displaying the state of each part of the bubble generating bath is not provided, the bath is, for example, provided with a function such as a circulating pump. If the strainer that keeps air from clogging is clogged and the bubble generating bath is operated in this state, the circulating pump will run idle, causing noise or damaging the pump. Even in a state where it is not suitable for jetting, it is impossible to take appropriate measures such as cleaning the strainer, and there is a disadvantage that the operation is started as it is.

Also, even if the bathtub water level is lower than the spout nozzle and the bathwater spouts onto the surface of the water, or if the temperature of the bathwater is too high and there is a risk of burns due to the spout bathwater, There is a danger of starting the operation without getting stuck.

(D) Means for Solving the Problems In the present invention, a bath water circulation channel is interposed between a bathtub body and a circulation pump, and an air intake unit is connected to the bathwater circulation channel so as to communicate with the bathtub. In a bubble generating bathtub capable of ejecting a bath containing air bubbles into the body, sensors for detecting the state of the bath water are provided in the bubble generating bath, and each sensor is provided on an operation panel via a control unit. Air bubbles configured to report the state of the bath water and the bubble generation bath by connecting to a display unit provided, operating the sensor when the circulating pump is not driven, and operating the display unit by the output of each sensor. It is intended to provide a display device for the generation bathtub.

(E) Function / Effect According to the present invention, the sensor that detects the state of bath water when the circulating pump is not driven is activated, and the display unit disposed on the operation panel unit is activated by the output of the sensor, so that the user The state of the bath water and the bubble generating bath is reported to the user.

Therefore, the user can grasp the state of the bath water and the bubble generating bath before driving the circulation pump, and perform an appropriate treatment at an early stage when an abnormality occurs in the bubble generating bath. Thus, it is possible to prevent an accident caused by the abnormality of the bubble generating bathtub and a failure of the bubble generating bathtub beforehand.

For example, when the circulating pump is stopped, the bathtub water level is detected by the bathwater level sensor, and when the bathwater level is lower than the position of the ejection nozzle, the fact is notified via the display unit. Promote hot water to the bathtub body,
By immersing the jet nozzle in the water, it is possible to prevent the bath water from spouting onto the surface of the water to generate noise and splash water.

In addition, a bath water temperature sensor is disposed in the circulation flow path to detect the bath water temperature, and if the bath water temperature is dangerously high, the bather is notified of this to the bather via the display unit. In addition, it is possible to prevent burns caused by the spouted hot water, and furthermore, it is possible to promote a decrease in the temperature of the hot water by immersion.

In particular, since the display section is provided on the operation panel section so that a bather can easily see the display section, the state of the bath water and the bubble generating bath can be reliably notified.
