Abstract

PURPOSE:To correctly install the bathtub by executing the control so that the bubble generating bathtub becomes inoperable, when a water level head in an installation job site is outside of a range set in advance, based on the water level head stored in a programmable ROM. CONSTITUTION:When hydraulic pressure is applied to a pressure sensor Sp and a construction completion confirming button is pressed, the pressure sensor Sp detects hydraulic pressure, and this detection value is converted to a water level and stored as a reference water level in a programmable ROM of a control part C. To a bathtub main body B whose installation work is ended in an installation job site, water for test working is poured to a reference line, and by pushing the construction completion confirming button, the pressure sensor Sp is allowed to detect hydraulic pressure, a water level conversion value of the pressure detection value and the reference water level are compared, and unless a difference of the water level conversion value and the reference water level exists within an allowable range, a display of normal position installation uncompletion is executed, and an inoperable state is held. In such a way, the bubble generating bathtub can be installed correctly.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to reference water level determination control during construction in a bubble-generating bathtub.

(b) Conventional technology Conventionally, bubble-generating bathtubs have a water pipe installed between the bathtub body and a bathwater circulation pump installed separately, and air is circulated while the bathwater is circulated by the operation of the pump. It is configured to inhale and spout bubble bath water from a jet nozzle (Japanese Patent Application Laid-open No. 59-135058).

The water level in the bathtub is constantly detected, and the system is configured to perform various controls by comparing this water level with a standard water level.This water level detection is extremely important in terms of safety and functionality. Therefore, this water level needs to be detected accurately.

(c) Problems to be solved by the invention However, even if the manufacturer sets a standard water level before shipping and sets the bubble-generating bathtub to operate normally based on the standard water level, the problem that occurs at the user's home, etc. If the relative vertical position of the bathtub body and the bath water circulation pump is different from the normal position due to an error in the installation work, the control of the bubble-generating bathtub will be disturbed and it will not operate normally, and the If the bath water circulation pump is operated with the water level still at the same level, problems such as seizure of the pump's mechanical seal and other shaft seals may occur.

(d) Means for solving the problem In this invention, a bath water circulation flow path is interposed between a bathtub body and a bath water circulation pump installed separately from the bathtub body,
In a bubble-generating bathtub, the bath water mixed with bubbles can be jetted out from a plurality of jetting nozzles provided in the bathtub body while sucking air through an air intake section connected to the flow path.
A programmable ROM is installed in the control unit of the bubble-generating bathtub, and the bathtub body and the circulation pump are installed in a specified relative position, and the bathtub body is operated on the bath water circulation pump when the bathtub body is filled with water to a specified water level. The water level head is stored in the programmable ROM, and at the installation site of the bubble generating bathtub, after the installation is completed, the bathtub body is filled with water up to the specified water level, and the water level head at the installation site and the water level head stored in the programmable ROM are set. When the water level head at the installation site is outside a preset range based on the water level head stored in the programmable ROM, the bubble generating bathtub is controlled to become inoperable. The purpose of the present invention is to provide a method for determining the quality of the installation position in a bathtub.

(e) Function/Effect In this invention, when the manufacturer installs the bathtub body and the circulation pump in a specified relative position before shipping and fills the bathtub body with water to a specified water level, the suction side of the bathwater circulation pump The head when the bathtub body and the circulation pump are installed in a specified relative position can be stored in the programmable ROM of the control unit.

At the installation site of the bubble-generating bathtub, after the installation is completed, the bathtub body is filled with water up to the specified water level, and the water level head at the installation site is compared with the water level head stored in the programmable ROM, and the water level at the installation site is determined. The head is
If the water level is higher (lower) than the water level head stored in the programmable ROM, it means that the bath water circulation pump is lower (higher) than the bathtub body, and it is easy to determine whether the installation position of the bathtub body and the bath water circulation pump is good or bad. can make judgments,
Based on this determination, the relative installation position of the bathtub body and the bath water circulation pump can be corrected.

In addition, since the water level head stored in the programmable ROM is an actual value measured when the bathtub body and the circulation pump are installed in a specified relative position, individual differences in the pressure sensor etc. for detecting the water level head may be considered. has been erased, allowing for accurate installation work of the bubble-generating bathtub.
