Description

  The present invention relates to a bathtub, a bathtub stopper, and a remaining hot water utilization system that make it possible to easily and easily use the remaining hot water in a bathtub by combining the remaining hot water utilization means and the remaining hot water transfer means.

In recent years, many of the residents have hoped to provide safe, secure, healthy and comfortable living spaces, and the incidental facilities of buildings such as houses have been considerably enhanced.
In particular, only human beings continue to consume a lot of energy such as huge amounts of oil, coal, and natural gas for heating and cooling in order to obtain comfortable living.
This is the destruction of the global environment by so-called mass consumption of finite energy.
Considering the maintenance of an environment friendly to the earth with few natural disasters, if we continue to consume oil, coal, and natural gas, which are valuable resources that cannot be regenerated, air pollution will increase and global warming will accelerate. .

  By the way, in recent years, it is said that the possibility of being hit by a natural disaster accompanying abnormal weather such as deadly wind and flood damage and desertification due to global warming is greatly increased, and this abnormal weather further accelerates the problem of water shortage.

Therefore, we focused on the use of the remaining hot water in the bathtub that everyone can use to prevent the destruction of the global environment.
In each household, the use of the remaining hot water in the bathtub is considerably advanced as the use of middle water for washing water.
However, the number of launderings has decreased as the nuclear family has progressed, and as a result, the remaining hot water has not been fully used and it has been thrown away directly into drainage, and the amount of water has increased significantly.
Various solutions such as attaching a 24-hour purification device are sold as a solution to this, but it is expensive and requires maintenance costs. Furthermore, it is difficult to manage the 24-hour purification device, and it is reported that there are many problems such as bacterial contamination in the bathtub. Yes.
In addition, according to technical information on the use of remaining hot water, most of the technical information that is used for flush toilets after collecting the intermediate water in the water tank and the technical disclosure that purifies and reuses the intermediate water are available. It is complicated and large and unsuitable for ordinary households in terms of equipment costs.
Also, there was no simple method or technical information for using the bathtub instead of the water tank and using the intermediate water for purposes other than the washing machine.

Next, Yokohama City has set out the target values for the global warming countermeasures regional promotion plan as follows.
<< Reduce greenhouse gas emissions per person in FY2010 by 6% or more compared to FY1990. >>
"As an energy-saving action that can be done right now at home", published in March 2007
