Problems solved by technology

[0003] However, with the device disclosed in Laid-Open Japanese Patent No. 2001-145676, since the gas is simply supplied to the liquid to be supplied to the bath through the air flow tube, sufficient gas cannot be mixed.
If not enough gas is mixed, the gas from the liquid being mixed in the bath will flow out immediately and not enough warming effect will be obtained

Embodiment 1

[0150]A bath mixing apparatus for supplying a mixed liquid including a gas-mixed liquid to a bath, said bath mixing apparatus having: (i) a first mixing chamber having a supply line through which the mixed liquid passes a supply line is fed for storing the mixed liquid at the bottom and having a first internal pressure maintained at a level above atmospheric pressure; (ii) a second mixing chamber having a supply line through which the mixed liquid passes A supply line is supplied for storing liquid at the bottom, and has a second internal pressure maintained at a level equal to or higher than atmospheric pressure but lower than the first pressure in the first mixing chamber; (iii) for The mixed liquid is circulated in the order of the first mixing chamber and the second mixing chamber through the chamber, and then it is returned to the bath; (iv) a liquid supply part for supplying the liquid to a tank comprising the corresponding bath, the first mixing chamber and the second mi...

Embodiment 2

[0152] The bath mixing apparatus according to Embodiment 1, further comprising: (I) a gas supply line that connects the first and second mixing chambers to the gas supply part via a valve; (II) a sensor that measures pressure in the chamber; (III) a control part that controls the opening / closing of the valve based on the pressure value detected by the sensor.

Embodiment 3

[0154] The bath mixing device according to embodiment 1 or 2, wherein the metering valve or the choke valve is arranged between the first mixing chamber and the second mixing chamber, and between the second mixing chamber and the bath.

Abstract

A fluid mixing apparatus configured to be connected to a tub, a liquid supply, and a gas supply, includes: a 1st pressurable liquid-storing chamber for storing liquid and mixing gas into liquid; a 2nd pressurable liquid-storing chamber for storing liquid and mixing gas into liquid; and a connection path connecting the 1st and 2nd liquid-storing chamber for supplying liquid from the 1st liquid-storing chamber to the 2nd liquid-storing chamber where the pressure inside the 2nd liquid-storing chamber is lower than the pressure inside the 1st liquid-storing chamber. The 2nd liquid-storing chamber is disposed downstream of the 1st liquid-storing chamber with respect to liquid flow.

Description

technical field [0001] The present invention generally relates to a fluid mixing device for a bath that mixes gas and liquid for supply to the bath. Background technique [0002] The device in Laid-Open Japanese Patent No. 2001-145676 is known as a device for mixing liquid with gas to supply such a bath. The apparatus disclosed in Laid-Open Japanese Patent No. 2001-145676 provides a bath, a nozzle injecting a jet into the bath, and an air inlet connected to the nozzle through an air flow tube. Thus, according to the device disclosed in Laid-Open Japanese Patent No. 2001-145676, the liquid that has been mixed with the gas in the bath can be supplied, and the effect of the warm bath can be enhanced. [0003] However, with the device disclosed in Laid-Open Japanese Patent No. 2001-145676, since the gas is simply supplied to the liquid to be supplied to the bath through the air flow tube, sufficient gas cannot be mixed. If not enough gas is mixed, the gas from the liquid being...
