  The present invention relates to a hot water bath provided with two different bathtubs filled with warm water and used to warm a forearm and a foot from the hand of a human body by placing them in the bathtub.

  Conventionally, many foot baths that have been put in a water tank filled with warm water and warmed with warm water have already been proposed. In many cases, the water in the water tank is warmed by a heater attached to the outside of the water tank of a size that can fit the feet, and the feet are put in the water tank for a warm bath. In this type of water bath, for example, a heater is arranged on the bottom back of a water tank of a size that can fit feet together, and is heated from the outside of the water tank, and a footrest is arranged in this water tank. There is one in which feet are warmed by convection of warm water (Patent Document 1). In order to further improve functionality, a heater is placed around the outer periphery of the hot water tank to heat it, and the hot water is jetted out as a jet jet, or a water channel switching device is added for drainage. Is known (Patent Document 2).

  In addition to this, two warm water tanks 101 and 102 as shown in FIG. 6 are arranged up and down as a warm bath 100 for the limbs which warms the hands and forearms using warm water in addition to warming the feet with warm water. The thing of the structure which is made is known. This warm bath 100 is provided with a warm water tank 101 of a size that can accept both feet on the lower side, and a person who intends to warm bath on the upper position can put the forearm portion and hand while sitting on a separate chair. The hot water tank 102 is configured to be integrally supported by the support legs 103. Then, one electric pump 104 is arranged so that the hot water supplied to the lower hot water tank 101 is also sent to the upper hot water tank 102, and the electric pump 104 circulates the hot water both in the upper and lower directions so that it can be heated.

Further, when performing replacement or cleaning, the filter can be removed and treated, so that it can be handled easily. Moreover, since these filters 23A and 33A are located in the groove parts 5a and 11a formed in the bathtub, at the time of use of a warm bath, the upper side of the groove part is covered with the protection plates 46 and 47 so that the bather H Can be used without touching. Further, if the filter is provided in front of the water inlet (or in the water absorption pipe), after the jet jet ejected with bubbles from the hot water outlet in the hot tub comes into contact with the user's hot bath portion. When sucked into the circulation pump from the water suction port, bubbles are prevented from being directly sucked into the pump, thereby preventing cavitation.

  As described above, the warm bath 1 (1A) of the present embodiment adjusts the temperature setting of the warm bath water to be handled by configuring the upper and lower hot tubs and the respective warm bath water circulation systems as separate systems. In addition to improving the effect, in addition to coping with the generation of waste products from different parts of the bath, it can be kept hygienically good, and the bathing effect can be kept mentally effective for the bather There is an effect.

  In the said embodiment, although a stationary bath may be sufficient, if it is set as the structure which attached the caster to the part provided with a lower hot tub as needed, it can move to arbitrary positions and can be used. Further, in the present invention, since the warm bath water circulation means is separated into the upper and lower systems, if a mechanism capable of adjusting the height is incorporated in the support column part, a flexible pipe is interposed in a part of the drain pipe. Thus, it is possible to change the height position of the upper hot tub according to the physique of the person to be bathed.
