Description

[Detailed description of the invention] Recently, the pine surge effect due to air bubbles in the bath,
The cleaning and heating effects have begun to be reconsidered, and in-bath foaming machines have begun to be widely used for home use. The in-bath foaming machine, which uses a whirlpool pump to generate water flow and generates air bubbles in the water flow through the Ventury effect, makes the human body feel a strong water flow directly and has a large amount of air bubbles, which can be applied to various parts of the human body. It is possible to guess and is becoming increasingly popular.

The present invention is an in-bath foaming machine using such a pump that, when used submerged in water, reliably supplies air from above the water surface, generates sufficient bubbles, and can be adjusted to suit the depth of various bathtubs. This makes it possible to take in air, and also improves the storability of the intake pipe.

An embodiment of the present invention will be described below based on the accompanying drawings. The bath foaming machine has a main body 1 as shown in Figure 1.
and a charger 32, and when in the bath, only the main body 1 is submerged in the bath, as shown in FIG. 6, and is activated to generate bubbles in the bath.

The main body 1 has a motor 2 inside it and a motor cover 3.
It is housed surrounded by a motor, and is sealed and installed in the chassis 4 with a motor O-ring 5. An impeller 7 is attached to the tip of the motor shaft 6. This motor shaft 6 is sealed with an oil seal 9. The impeller 7 rotates in the casing 10, sucks up water, and sends a water stream to the foaming section 11, forming a spiral pump. In the foaming section 11, air is taken in from the air intake passage 12 above the water surface due to the Ventilly effect, and is discharged into the bath water together with the water flow as bubbles. The motor 2 is rotated by being supplied with energy by a storage battery 13, and the storage battery 13 is housed in a battery case 14 and wired to a main body control circuit 15 that controls the entire main body 1. Main body control circuit 15
is sealed by a circuit case 16. The water sucked up by the impeller 7 is filtered by a filter 18 attached to a filter case 17 to prevent dirt from entering the casing 10. The storage battery 13 has a charging secondary coil 19 provided in a coil case 20,
The charger 32 is charged from the charging primary coil 34 through the wall of the charger case 33 . A charging circuit 35 for this purpose is housed within the charger 32. Third
The figure shows the principle of foaming in water. Water sucked up from the water suction port 21 of the casing 10 enters the foaming section 11 which is connected to the casing outlet 22 through the foaming tube inlet 23, and is passed through the constriction section 25. The flow speed increases, enters the widening section 26, and exits the outlet section 27.
I'm leaving. Due to the water flow at this time, the air chamber 2
Outside air is sucked in through the intake port 24 from the air intake passage 12, which is open above the water surface, so that the pressure inside the tank 8 is reduced by the Ventury effect.
Since it is discharged along with the water stream through the outlet section 27 and the nozzle 29, it becomes bubbles and flies into the bath.

FIGS. 4 and 5 show the relationship between the foamed portion 11, the air intake passage 12, and a flexible bellows-shaped hose 38 for air intake that connects them. As shown in this figure, the air intake passage 12 is an expandable and retractable structure consisting of a fixed pipe 12a fixed to the main body 1, a first movable pipe 12b that can slide concentrically thereto, and a second movable pipe 12c. ,,
If you stretch it out, it will stay in that position. These pipes are housed in the side of the main body 1, and when the main body 1 is used submerged in a bathtub, they are extended to any position according to the depth to ensure that air can be taken in.

In addition, in order to extend the air intake passage longer in the limited space inside the main body 1 and to accommodate the depth, the flexible hose 38 connected to the fixed pipe 12a is fitted into the inner wall of the fixed pipe 12a, and the end of the hose 38 is The part 38a is used as a stopper to prevent the movable pipe 12b from falling off, and the movable pipe 1
2c has a smaller diameter than the hose 38, and the bottom part is the hose 3.
8 inside the constricted part 38 of the hose 38.
I hit point b as a stopper. Further, the first stage constricted portion 38b of the hose 38 is sandwiched between the ribs 1a provided on the main body 1, thereby eliminating the possibility of the hose coming off and ensuring a secure connection with easy assembly. Note that when the movable pipe 12c is stored, the lower end is located within the hose 38, which eliminates movement of the pipe during storage, improving product quality and usability. The lower end of the movable pipe 12c is constricted into a substantially spherical shape, and a through hole 12d is formed in the center thereof. Noise is generated when air bubbles get mixed into the water flow, and the air bubbles leak outside through the air intake passage 12. Therefore, the lower end of the movable pipe is narrowed down to block part of the air bubbles, and if the air bubbles do not flow in as it is, the lower end of the movable pipe is narrowed down. Because it is bad, a through hole is provided. Due to the presence of the through holes 12a, the foamed portion 1
It can be expected to have the effect of blocking the noise generated from 1. The spherical bottom of the pipe 12c makes it easy to enter the inside of the hose 38, and even if water enters from the top of the pipe 12c, the small through hole 12d is at the lowest position. Water does not accumulate in the pipe, making it easy to use,
Good in appearance and hygiene. Note that 39 is pipe 1
A cap provided at the upper end of 2c forms a detour for the air.

As is clear from the above embodiments, the in-bath foaming machine of the present invention obtains a pine surge effect, a heating effect, and a cleaning effect using water flow and air bubbles, and fully exhibits its original functions. The passage ensures air intake, making it usable regardless of the type of bathtub, and the provision of through holes in the movable pipe also effectively muffles noise generated by the foam section.
