Abstract

PROBLEM TO BE SOLVED: To improve sweet smell durability and effective utilization without lowering the purifying function of a filter part by connecting a jet nozzle to the hot water ejection pipe of a circulation route, sucking air containing a fragrance component from a fragrance supply source, supplying it to hot water as air bubbles and filling a fragrance inside a bathroom. SOLUTION: When a circulation pump 2 is operated, the hot water sucked through a filter 6 is purified through the filter part 3 and jetted from the jet nozzle 9 which is a fragrance adding device 8. By the ejector action of the jet nozzle 9 at the time of the jetting, the air inside the atmosphere is sucked through the fragrance supply source 10. Then, the air is turned to the air bubbles, distributed in the hot water and turned to a jet flow. Since the air is brought into contact with the fragrance raw material of a fragrance bag and contains the fragrance component, it is filled inside the bathroom. At the time, only the fine amount of the fragrance component is dissolved in the hot water and the fragrance is obtained without clogging the filter part 3 or deteriorating the purifying function.

Next, the operation of the bath tub circulating filtration device with an aroma addition device according to the present invention will be described. The basic function of the bath tub circulating filtration device 1 is that when the circulating pump 2 is operated, it is sucked through the filter 6. The hot water is supplied to the filtration unit 3
Is purified when passing through, and is jetted and circulated from a jet nozzle 9 which is an aroma addition device 8.

As described above, when the hot water is jetted from the jet nozzle 9, the air in the atmosphere is released by the ejector action of the jet nozzle 9 to the case 14 in the fragrance supply source 10.
When the air is sucked through the air supply cylinder 33 through the air flow chamber 17 inside, the air is dispersed as bubbles in warm water to form a jet stream.

The air to be sucked is in contact with the fragrance material in the fragrance bag 18 when passing through the air circulation chamber 17,
Supplied to warm water as bubbles containing volatile aroma components, even if a small amount of the aroma components dissolves into the warm water due to gas-liquid contact during the rising process of the bubbles, the remaining aroma components remain undissolved in the warm water Is mostly diffused into the atmosphere by the energy of the bursting of bubbles on the hot water surface,
Fill the bathroom.

Here, the function of the jet nozzle 9 is that the hot water flowing from the inflow cylinder 27 into the turbulence chamber 26 flows from the cylindrical inflow cylinder 27 into the large-volume, rectangular turbulence chamber 26. At the same time, it collides with and disturbs the bottom wall 24 to increase the Reynolds number to form a turbulent flow and a vortex. Since the flow path to the section 25 is a right angle, turbulent flow is promoted, and the hot water discharged from the tip opening 25 is discharged to the discharge side cylindrical body 34.
Flow from the small-diameter jet flow generating hole 39 on the inflow side of the jet flow chamber 36 having a large cross-sectional area, the flow velocity is increased, the turbulent flow state is promoted, and the Reynolds number is increased. At this time, the jet flow chamber 36 with respect to the air supply cylinder 33 at atmospheric pressure is in a negative pressure state and the Reynolds number is high, so that air is drawn from the air supply cylinder 33 and hot water is turbulent. As a result, bubbles are generated and dispersed, so that jet water is jetted out of the jet flow chamber 36 even at a depth of 50 cm in the bathtub X.

Since the fragrance supply source 10 containing 18 in the air circulation chamber 17 is connected, only a small amount of the volatile fragrance component dissolves in the warm water, so that the clogging of the filtration unit 3 does not occur and the purification function is deteriorated. Most of the fragrance components can be dispersed in the atmosphere, so that the entire bathroom can be given a pleasant scent. Since the raw material is powder and granules and packed in the fragrance bag 18, it is easy to handle, and since only the fragrance component volatilized from the fragrance raw material can be used by suction, the fragrance raw material can be used for a long time, and Aroma components Since the volatilization and diffusion can be reliably performed, the effective use of the fragrance component can be effectively used without waste. Further, the jet nozzle 9 does not require any driving force, and the volatilization amount of the fragrance component is adjusted by the flow rate of the hot water to the jet nozzle 9, The intensity of the incense is also possible.
