Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub heat retaining heater that is electrically connected to a bathtub faucet.

In recent years, many residents desire to provide a safe, secure, healthy, and comfortable living space, and the ancillary facilities of buildings such as houses have been considerably enhanced.
On the other hand, there are many sanitation problems associated with the hotbeds and growth of various bacteria in the piping of systems that use bath water for washing machines and reheating systems for baths that have already been commercialized.

Bath water utilization systems for washing machines on the market take out the remaining hot water directly from the reheating portion on the upstream side of the bathtub faucet or the side of the bathtub, and suck it up with a pump mounted on the washing machine.
However, since the water level in the bathtub fluctuates every time one enters and exits the bathtub when bathing, the water level in the pipe connecting the bathtub and the washing machine also fluctuates. Bacteria in the plumbing also enter and leave the bathtub, leading to contamination.

The main cause of the bacteria contamination problem is the bacteria contamination from the reheating pipe in the bath reheating system that is installed almost as standard.
In addition, it includes a jet bath system that circulates hot water and a nano (micro) bubble system, and this point is viewed as a problem. It is no exaggeration.

Based on the technical concept of the present invention, we have realized a "bathing style that does not reheat" that eliminates bacteria contamination as much as possible, and eliminates urinary tract infections (cervical cancer, etc.) caused by bacteria contamination due to bathing and does not harm health. We believe that the spread of housing equipment is important, and that it is essential to extend healthy life expectancy without getting sick and to reduce national medical expenses.

In order to solve the problem of bacterial contamination in the bathtub, we believe that the first priority is to realize a bathing style that does not require reheating.
Therefore, in order to maintain the water temperature without a bath reheating system, it is generally necessary to add hot water, or use a simple heater with an electric cord for the bath to keep the water in the bathtub at an appropriate temperature. There is a way.
However, there are concerns about burns from hot water and electric shock from simple heaters, so it is not safe for the elderly and children.

Focusing on this concern, we investigated technical information aiming for a safe and comfortable bathing style that is friendly to people and eliminates burns from hot water and electric shock accidents with simple heaters.
As a result, there was technical information about a JIS-standard high-insulation bathtub with a temperature drop of 2.5°C or less after four hours had passed.
However, I couldn't find any technical information on hot tub heaters.
In addition, <Patent Document 1> and <Patent Document 2> existed regarding a bathing style in which fresh water is used each time without reheating by using the remaining hot water. Search failed.
<Patent Document 1> Patent No. 5179778 <Patent Document 2> Patent No. 5180136

The reheating function has become standard in recent unit bath tubs and single bath tubs.
Hygiene problems have occurred due to the contamination of various bacteria derived from this reheating pipe.
In order to eliminate this problem, it is best to eliminate the "additional cooking function" that is popular in many homes.
However, if the "reheating function" is removed, even if the hot water is covered with heat insulating material, when the hot water cools down, there is no choice but to cover it with hot water or use a simple heater with an electric cord for the bath. Since it is the current situation, we would like to solve the safety and hygiene problems by providing a hot tub with a built-in electric heater with an electric heater energization system of this technology.

Therefore, we provide a hygienic new bathing style that is friendly to all people regardless of age and children, safe and hygienic, and free from contamination by bacteria.
Furthermore, by making it available for use by introducing it into the bathroom through piping from the air supply equipment for nanobubble generators and oxygen-enriched air supply equipment for medical use, it can be easily used by patients using oxygen supply cylinders for respiratory diseases. We want to provide a safe and comfortable bathroom equipment that can be used.

In order to achieve the above object, the present invention has taken the following technical measures.
First,
In a hot tub with a built-in electric heater that can maintain an appropriate temperature without a reheating function ,

Conceptual diagram of a unit bath equipped with a heated bathtub with built-in electric heater

EMBODIMENT OF THE INVENTION Hereinafter, Example 1 is described based on the conceptual diagram of FIG. 1 for embodiment of this invention.

FIG. 1 is a unit bath 1 illustrating the first and second technical means, and the structure of a hot tub 10 with a built-in electric heater is that an electric heater 12 is arranged between the bottom of the tub and a heat insulating material 19, The electric heater 12 is energized only when the electrically interlocked bathtub faucet 25 is closed and in the bathing mode, the electric heater 12 is energized to the arbitrarily set temperature within the arbitrarily set energization time setting range, and the electric heater turns ON and OFF. It is a unit bath equipped with a built-in heat-retaining bathtub 10. - 特許庁

The electric heater 12 of the thermal insulation bathtub 10 with built-in electric heater is energized only when the bathtub faucet 25 is closed, and the energization of the electric heater 12 is ON/OFF for the set temperature only within the arbitrarily set energization time setting range. By repeating this process, the hot water is kept at an appropriate temperature.

The method of maintaining the set temperature of the hot water is to turn on/off the heater temperature within the range of 2 °C using a thermostat system for any set temperature.
There is also a method of keeping the heater temperature constant with respect to an arbitrarily set temperature.

The electric heater 12 of the hot tub 10 with a built-in electric heater is a heat detection thermostat power ON/OFF type, and a safety excessive temperature rise prevention device is also incorporated, and power is cut off when the temperature reaches 45°C.
The electric heater 12 of the hot tub 10 with a built-in electric heater employs a thin seat heater 15 which is flexible in bending and arrangement.

The explanation is based on the bathing time zone of a general standard household.
After cleaning the bathtub and starting to fill it with hot water at 7:30 pm, the filling of hot water at a suitable temperature of approximately 40°C is completed at 8:00 pm.
When the bathing time is from 8:00 pm to 11:00 pm, the electric heater 12 is energized only for 3 hours from 8:00 pm to 11:00 pm, and the electric heater 12 is repeatedly turned ON/OFF. The water temperature is maintained at approximately 40°C, which is the optimum temperature of 10.
The setting range of the energization time of the electric heater 12 of the electric heater built-in thermal insulation bathtub 10 is designed so that the period, time zone and temperature can be arbitrarily set only during the cold winter season.

In the first embodiment, the electric heater 12 is energized and turned ON/OFF repeatedly within an arbitrarily set energization time setting range only in the bathing mode in which the electrically interlocked bathtub faucet 25 is closed. If is opened, the power supply to the electric heater 12 is cut off regardless of the power supply time setting range from 8:00 pm to 11:00 pm.

In this case, all the remaining hot water in the bathtub will be drained from the time when the bathtub faucet 25 is opened.
This is inconvenient because the remaining hot water cannot be used, so in Japanese Patent No. 5180136 and Japanese Patent Application No. 2014-057419, which are a system for using the remaining hot water in the bath, a technique that is used for the toilet bowl and the washing machine of the 80 places where the remaining hot water is used in the bathtub is proposed. Effective water saving can be planned in each household by tying.

The spread and expansion of a bathing style in which the use of leftover hot water and the hot tub 10 with a built-in electric heater are used together to allow fresh hot water to be used each time without reheating the water will help prevent urinary tract infections (cervical cancer, etc.) caused by contamination with bacteria. ) can be eliminated, health life expectancy can be extended, and national medical expenses can be reduced.
This will bring us one step closer to building a “healthy, comfortable, and environmentally friendly home” that extends healthy life expectancy, and as a result, there is a high possibility that this will lead to a reduction in national medical expenses.

The opening/closing conditions of the bathtub faucet 25 and the drain valve 35 in each mode are as follows in the technical configuration for using the remaining hot water in the bathtub for the toilet and washing machine disclosed in Japanese Patent Application No. 2014-057419.
・In bathing mode, bathtub faucet 25 is closed/drain valve 35 is closed ・In remaining hot water use mode, bathtub faucet 25 is open/drain valve 35 is closed ・In cleaning mode, bathtub faucet 25 is open/drain valve 35 is open

In the first embodiment, the electric heater built-in thermal insulation bathtub 10 is of the electric heater type, but the heat source is not limited to electricity. It may be a heat pump system that utilizes, and is not limited to an electric heater system.

Next, the hot water circulation type nanobubble system, which is sold as an option recently, also leads to contamination with various bacteria, so we would like to recommend another method, a nanobubble system using compressed air.
This nanobubble system is a method of generating nanobubbles in bath water from a nanobubble generator through a tube 56 with compressed air from a nanobubble generator air valve 55 attached to the inner wall surface of the bathroom.
A sucker is attached to the tube 56 so that the tube 56 can be attached to and removed from the inner wall of the hot tub 10 with a built-in electric heater.
The nanobubble generator has a porous ceramic component attached to the tip of the tube 56 to generate and release nanobubbles in hot water.
The porous ceramic parts are covered with a protective cover made of a soft material, except for the part that emits nanobubbles, which protects the bathtub from scratches and has a weight that allows it to be submerged in water.

In addition, there are several methods for nanobubble generators.
For example, when compressed air is passed through an ejector at high speed, hot water in the bathtub is sucked up, so many techniques have been introduced, such as a method of mixing and passing this gas-liquid fluid through a mixer to generate nanobubbles.

The medical oxygen-rich air from the medical oxygen-rich air generator is easily taken out from the medical oxygen-rich air valve 65 attached to the inner wall surface of the bathroom and used for patients suffering from respiratory system diseases.
Medical oxygen-enriched air is supplied through tubing 66 connected to medical oxygen-enriched air valve 65 .
A mask is attached to the tip of the tube 66 .

A medical oxygen-enriched air generator equipped with a membrane that separates oxygen and nitrogen from air produces oxygen-enriched air and nitrogen-enriched air, so it is efficient to use nitrogen-enriched air in a nanobubble system.
Furthermore, since it is scientifically proven that carbon dioxide gas has a high effect of warming the body even when the water temperature is as low as 39°C, carbon dioxide gas may be used in the nanobubble system.
When using nitrogen-rich air or carbon dioxide gas, ventilate the bathroom sufficiently.

You can get one step closer to building a "housing that emphasizes comfort, health and the environment".
