Abstract
Abstract A foot bath including a bath body for containing hot water, in which a foot is to be inserted, the bath body having a cover having an opening therein. A ceramic layer and a heater are provided in the cover so that the heater heats the ceramic layer to produce far infrared rays to irradiate the foot and hot water in the bath body. A structure is provided beneath the bath body for providing vibration to the foot. A pump is connected to the vibration structure so as to be driven thereby and an air transferring pipe is connected between the pump and the bottom of the bath body to transfer air therethrough while the air is heated by the far infrared radiation. A nozzle is provided in the bath body to mix the heated air and hot water and to eject the mixture of heated air and hot water at the surface of the hot water in a jet water stream.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
209 words
A foot bath comprising: a bath body for containing hot water, which a foot is to enter, said bath body having a cover having an opening therein; far infrared ray radiating means, provided in said cover, for radiating far infrared rays to the foot and the hot water, said radiating means including a ceramic layer in the cover and heating means for heating said ceramic layer to produce said far infrared rays; vibrating means, provided under said bath body, for providing vibration to the foot in said bath body; and means for generating a jet water stream in said bath body, said generating means, including a pump connected to said vibrating means so as to be driven by said vibrating means, an air transferring pipe connecting said pump and the bottom of said bath body to transfer air from said pump to the bottom of said bath body while the air is being heated by said infrared rays, and a nozzle provided in said bath body to mix the air heated by said infrared rays with the hot water in said bath body to eject the jet water stream as a mixture of heated air and hot water at the surface of the hot water in said bath body.
Claim 2
Dependent Claim
209 words
A foot bath comprising: a bath body for containing hot water, which a foot is to enter, said bath body having a cover having an opening therein; far infrared ray radiating means, provided in said cover, for radiating far infrared rays to the foot and the hot water, said radiating means including a ceramic layer in the cover and heating means for heating said ceramic layer to produce said far infrared rays; vibrating means, provided under said bath body, for providing vibration to the foot in said bath body; and means for generating a jet water stream in said bath body, said generating means, including a pump connected to said vibrating means so as to be driven by said vibrating means, an air transferring pipe connecting said pump and the bottom of said bath body to transfer air from said pump to the bottom of said bath body while the air is being heated by said infrared rays, and a nozzle provided in said bath body to mix the air heated by said infrared rays with the hot water in said bath body to eject the jet water stream as a mixture of heated air and hot water at the surface of the hot water in said bath body.
