【発明の詳細な説明】 産業上の利用分野 本発明は風呂釜で浴槽内の水を加熱するとともに、加熱
中に水道水圧を間欠的に浴槽内に導くことにより浴槽内
を撹拌する風呂装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath device for heating water in a bathtub with a bath kettle and stirring tap water pressure by intermittently guiding tap water pressure into the bathtub during heating. It is a thing.
従来例の構成とその問題点 従来の風呂装置においては、自然循環式で加熱するもの

高温水は浴槽の水の上層部に流出して高温層を形成して

う欠点があった。Configuration of Conventional Example and Problems Thereof In many conventional bath devices, heating is performed by a natural circulation system, and two circulating pipes arranged vertically are connected to boil the bathtub and bathtub. In this case, the upper circulation pipe sends very hot water back to the bathtub, and the hot water flows out to the upper layer of the water in the bathtub to form a high temperature layer. Unless it was not, the temperature distribution was such that the upper layer was hot and the lower layer was cool. For this reason, the user needs to stir the bath water before use or using a tool, and if the average hot water temperature is higher than the desired hot water temperature, add water, and conversely, if it is lukewarm, it is necessary to perform heating operation again. . Therefore, there is a drawback that it takes time and effort to stir by hand, and how much boiling at that time cannot be confirmed unless the stirring work is performed.
また従来の別の風呂装置においては、蒸気や高温水を給
湯器でつくり、これを浴槽下部に導いて浴槽内に放出す

いうことも起る。従ってこの方式においては、湯の量が
増え過ぎて使い勝手が悪いこと及び増え過ぎると湯の無
駄という欠点を有していた。Also, in another conventional bath device, steam or high-temperature water is created by a water heater, and this is guided to the lower part of the bathtub and discharged into the bathtub to heat the bathwater while pouring the high-temperature water into the bathtub. There is one. Since this method does not have the natural circulation heating unit of the conventional example, it is necessary to continuously inject high-temperature water from the beginning to the end of heating, and the amount of water in the bath increases considerably after the end of heating. Depending on the amount and temperature of the water, the bath water may overflow from the bath after heating. Therefore, in this method, there is a drawback that the amount of hot water is too large and the usability is poor, and if the amount is too large, the hot water is wasted.

り、かつ回転部分を有するので一般的に長期間の耐久性
には信頼性が十分確保できないこと及び一般に機械式と
なるため運転音が高いという欠点を有していた。As another method, a forced circulation device (circulation pump, air pump, etc.) is installed in the middle of the natural circulation type circulation pipe.
There is a method in which high temperature water is made to have an appropriate temperature by increasing the amount of circulation by intervening with, and the bath water in the bath is also stirred by the force of the jet flow. However, this device itself has the drawbacks that it is inevitably expensive, and that it has a rotating part, so generally it is not possible to ensure sufficient reliability for long-term durability, and that it is generally mechanical and the operating noise is high. Was there.
このため安価でかつ信頼性が高く、運転音も低く、浴槽
水の増え過ぎもなく、浴槽内の湯の温度差を少なくする
方法の開発が課題であった。Therefore, the development of a method that is inexpensive and highly reliable, has a low operating noise, does not increase the bath water too much, and reduces the temperature difference of the hot water in the bath is an issue.

極めて便利性の高いものである。The operation of the above configuration will be described below. As shown in FIG. 1 and FIG. 2, the bath apparatus configured in this manner first causes the controller 14 to turn on the bath control valve 6 to ignite the natural circulation heating burner 5 for natural circulation. The heat exchanger 3 for heating is heated. Bath water 2
Circulates by natural convection as shown by the arrow in FIG. 1, and flows out again into the bathtub 1 through the circulation pipe 4. At this time, the hot water flowing out is extremely hot, and the upper layer of the bath water 2 becomes hot. When the above heating time t 1 has elapsed, as shown in FIG. 2, the controller 14 turns on the hot water supply control valve 9 to ignite the hot water supply heating burner 8 and, at the same time, turns on the hot water supply valve 11 as well. Exchanger 7
The hot water warmed by is discharged from the pipe tip 12 through the water passage 10 toward the bathtub 1 as shown by the arrow. At this time, as shown in FIG. 2, air is sucked from the communication pipe 13 to a portion having a negative pressure due to the hot water jetted from the pipe tip 12, and flows into the bathtub 1 together with the hot water flowing out. These flows agitate the inside of the bath, and the temperature difference of the hot water in the bath disappears. The state as shown in FIG. 2 is continued for time t 2, but while the bath water 2 is being heated, the bath control valve (SV 1 ) 6 of the burner 5 for natural circulation heating is continuously turned on, as shown in FIG. Hot water supply valve (SV 2 ) 11 and hot water supply control valve (SV 3 ) 9
The controller 14 performs the sequence control so as to perform the OFF operation during the time t 1 and the ON operation during the time t 2. Advantageous Effects of the Invention According to the present embodiment, the following effects are obtained. Have
It is extremely convenient.
（１） 浴槽内の湯温の温度差が少なくなり、手や道具
