Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a mechanism for sterilizing hot water in a bathtub, and more specifically, the present invention relates to a mechanism for sterilizing hot water in a bathtub, and more specifically, to sterilize hot water in a bathtub through a hot water boiler or an electric water heater using gas or oil as a heat source. This invention relates to improvements to enable sterilization.

[Conventional technology]

In general, bathtubs come in a variety of shapes, from large bathtubs installed in public baths used by an unspecified number of people to small ones for general household use, and are made of various materials such as tile, rock, synthetic resin, stainless steel, enamel, and wood. materials are used. In addition, hot water for these bathtubs can be directly heated in attached pots, or can be supplied with hot water boiled in a hot water boiler or the like.

[The problem that the idea aims to solve]

However, in bathtubs such as those mentioned above, dirt and waste matter adhere to the side walls and bottom wall surface, and various kinds of bacteria and pathogens breed, so when the bathtub is filled with hot water, these dirt and waste matter are removed. Microscopic objects, bacteria, pathogens, etc. will float in the water. Therefore, in public baths, the hot water in the bathtub is guided to a filter installed outside and circulated through the filter and returned to the bathtub to purify the water. In the case of the purification method using a vessel, it is only possible to remove microscopic substances such as dirt and waste products, and bacteria and pathogens return to the bathtub without being sterilized. It is also possible to mix sterilizing chemicals into hot water, but this cannot be used in large quantities because it may harm the eyes and skin, and a strong sterilizing effect cannot be obtained. On the other hand, in the case of ordinary home baths, the reality is that no consideration is given to sterilizing the water in the bathtub.

The present invention is an attempt to improve the above-mentioned problems, and the problem of the present invention is to heat the hot water in the bathtub regardless of the size of the bathtub, such as a public bath or a home bath. The point is to make it possible to sterilize and improve its cleanliness.

That is, the present invention is characterized in that sterilization can be carried out by heating the water in the bathtub to a high temperature using the thermal power or water temperature of a hot water boiler, etc. The specific means and effects are as follows.

[Means to solve the problem]

A water supply pipe is installed from the bathtub via a pump to the sterilizing pot placed in correspondence with the burner in the hot water boiler or the heat collection pipe placed in the water chamber (hot water storage room) of the hot water boiler or electric water heater. A water pipe extending from the hot water discharge side of the sterilizing pot or the heat collecting pipe body is connected to the cooler, or a water pipe extending from the heat collecting pipe body is passed through the bottom of the water chamber (hot water storage room). After that, connect the water pipe to the bathtub.

[Effect]

When using a hot water boiler, while the burner is ignited, hot water from the bathtub is pumped through a pump to a sterilizing pot placed in correspondence with the burner, and the hot water is heated and sterilized in the sterilizing pot. After that, it can be cooled to an appropriate temperature using a cooler and then circulated back into the bathtub.However, when extinguishing the burner or using an electric water heater, the water chamber (hot water storage chamber)
The temperature of the hot water in the bathtub is sent to the heat collecting pipe placed inside.
The heat collecting pipe can be heated and sterilized using hot water in the water chamber (hot water storage chamber).

Next, its effect will be explained.

When the water chamber (hot water storage chamber) 3 of the hot water boiler A is filled with water and the bathtub A is filled with water so that the water level is slightly higher than the opening of the water pipe 19, when the burner 5 is ignited, its combustion flame While the sterilizing pot 6 is heated by this, the combustion flame and combustion heat rise in the smoke chamber 7 and heat the heat absorption pipes 9 horizontally placed in the smoke chamber 7. By heating the heat-absorbing tube 9 in this way, the water in the heat-absorbing tube 9 is gradually heated to become hot water, and the hot water moves inside the heat-absorbing tube 9 toward the upper end and reaches the manifold pipe 10. However, since the heat absorption tube 9 is communicated with the manifold tube 10 through the throttle hole 11, the amount of flow into the manifold tube 10 is restricted by the throttle hole 11, and the heat absorption tube The residence time of the hot water in 9 becomes longer, and the effect of heating the water to a higher temperature can be obtained. The hot water heated in this way and sent to the manifold pipe 10 has a temperature difference depending on the length of each heat absorption pipe 9 and its horizontal position, but each hot water is mixed within the manifold pipe 10 and is uniform. temperature, and is discharged into the water chamber (hot water storage chamber) 3 from the relief hole 12 opening in the manifold pipe 10, and the water is discharged into the water chamber (hot water storage chamber) 3.
The effect of increasing the temperature of water can be obtained. The hot water raised in temperature in the water chamber (hot water storage chamber) 3 in this way is fed to the hot water tap 36.
Hot water is supplied to bathtub B through the opening operation.

On the other hand, while the sterilizing pot 6 is being heated by the combustion flame of the burner 5 as described above, the bathtub A is filled with water so that the water level is slightly higher than the opening of the water pipe 19. As a result, when the pump 17 is operated, the water in the bathtub B is sent to the filter 18, where fine particles such as dirt and waste are removed, and then the water is transferred to the heating chamber 13 of the sterilization pot 6. will be pumped to.
The temperature is then raised to a high temperature in the heating chamber 13, and a part of it enters the heating chambers 14, 14, and the U
The temperature is raised to a higher temperature in the character-shaped heating branch pipe 15. The hot water heated to this high temperature is heated through the heating pipe 1.
Return to the heating chamber 13 again from 4 and 14, and return to the heating chamber 1.
It is mixed with the hot water in 3. By raising the temperature of the hot water to a high temperature in this way, the effect of sterilizing bacteria, pathogens, etc. in the bath water is obtained. Also, since the water from the bathtub B is sequentially sent to the heating chamber 13 by the pump 17, the high temperature hot water sterilized as described above is sent out from the water pipe 21 and is sent to the water chamber 23 in the cooler 20.
Enter a. Then, from the same water chamber 23a, the heat radiation pipe 24...
The water is cooled to an appropriate temperature by the water in the water tank 22 while passing through the water chamber 23b, and returns to the bathtub B via the water pipe 25.

Also, the temperature of the water in the water tank 22 will be raised by cooling the heat radiation pipes 24, and this heated water will flow through the water pipe 2 that communicates with the water supply.
It is sent into the water storage tank 27 by the water pressure of 6. Water is supplied from the water storage tank 27 to the water chamber 3 of the hot water boiler A via a water pipe 29, or the water pipe 2 is connected to an arbitrary location via a switching valve 30.
9' is supplied with water.

On the other hand, when the water in the water chamber 3 of the hot water boiler A is heated to a high temperature, the burner 5 is extinguished, and the heating effect of the sterilizing pot 6 by the combustion flame of the burner 5 is no longer obtained. is the switching valve 3
When the water in the bathtub B is sent to the heat collecting pipe body 34 disposed in the water chamber (hot water storage room) 3 through the switching operation in step 2, the water pumped through the pump 17 flows through the base constituting the heat collecting pipe body 34. While passing through the tubes 34a, 34a and the heat collection thin tube 34b, it is heated by the high temperature hot water in the water chamber (hot water storage chamber) 3, thereby achieving a sterilizing effect on bacteria and pathogens. The heated and sterilized hot water is then sent from the heat collecting pipe body 34 to the cooler 20 via the water pipe 35,
After being cooled down to an appropriate temperature by the cooler 20, it returns to the bathtub B.

In addition, when using an electric water heater, since it does not have a built-in burner, the heat collecting pipe 34 is placed in the water chamber (hot water storage room) of the electric water heater. On the other hand, pump 17 is connected to bathtub B.
The water pipes 19 and 33 extending further are communicated with each other, and the water pipe 35 extending from the discharge side of the heat collecting pipe body 34 is communicated with the cooler 20. If the water pipe 25 is connected to the bathtub B, the same sterilizing effect as described above can be obtained. In this case, since there is a temperature difference between the hot water temperature at the top and bottom of the water chamber (hot water storage chamber), the water pipe 35 extending from the hot water discharge side of the heat collecting pipe body 34 is connected to the bottom of the water chamber (hot water storage chamber). If it is guided, the water pipe 35 can be cooled to an appropriate temperature by the low-temperature water in the same section, and the cooler 20 is no longer necessary, making it possible to reduce its manufacturing cost.

The present invention is constructed as described above.
As mentioned above, hot water from the bathtub is supplied via a pump to the sterilizing pot placed in correspondence with the burner in the hot water boiler or to the heat collecting pipe placed in the water chamber (hot water storage chamber) of the hot water boiler or electric water heater. The cleanliness of the hot water in the bathtub can be improved by circulating the hot water by heating it in a sterilizing pot or heat collecting pipe, sterilizing it, cooling it to an appropriate temperature, and returning it to the bathtub. It came to this.
