Description

[Detailed description of the invention] The object of the invention is to provide an easy-to-use in-bath foaming machine that generates water flow and bubbles in hot water in a bathtub and has a pine surge effect, a heating effect, and a cleaning effect.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, the main body 1 is attached to the wall of bathtub A or is used completely submerged in water, and the second
As shown in FIGS. 3 and 3, it consists of a main body 1 and a charger 2.

Inside the main body 1, a storage battery 3 is placed in a case 4 sealed by heat welding, and installed in a recess 5 with a wall 5' in a part of the main body 1.

Further, the main body 1 has a built-in electric motor 6, which is attached to a chassis 7 and sealed with a cover 8 and an O-ring 9.

A casing 10 is attached to the opposite side of the chassis 7 from the electric motor 6, and forms a spiral chamber between the casing 10 and the chassis 7.

A Hanegerman 11 is attached to the tip of the shaft of the electric motor 6, and by rotating in the center of the casing 10, the Hanegerman 11 sucks water from the bottom of the casing 10 to form a centrifugal pump.

The water flow generated in the casing 10 is guided to the Venturi tube 12.

The water flow constricted by the nozzle part 12a of the Venturi tube 12 is
The flow rate is increased and the fluid is discharged from the outlet 12b.

At that time, the intake part 12c is connected to the expandable intake pipe 13.
More air is sucked in, and a water stream and bubbles are ejected from the outlet 12b.

This water flow and air bubbles are generated by a spout 1a provided on the front of the main body 1.
More erupts.

The intake pipe 13 is formed of a plurality of pipes 13a having different diameters, has an expandable and contractible structure, and is made to protrude above the water surface in the bathtub A to suck in air.

At the bottom of the casing 10 is a filter 14 made of mesh and foam, which can be attached and detached from the outside by a filter case 15 to protect the casing 10 from foreign matter.

The filter 14 is connected to an inlet 16 at the bottom and lower side of the bathtub A communicating with the interior of the bathtub A.

Further, a coil case 18 containing a secondary coil 17 is attached to the chassis 7 in a sealed state with an O-ring 19, and extends from the bottom surface of the main body 1.

Further, a control circuit 20 containing control parts and the like is built into the upper part of the electric motor 6, and this control circuit 20 is also covered with a cover 21 which is thermally welded and has a sealed structure.

As shown in FIG. 3, only the storage battery 3 is installed in a recess 5 having a lid 5', and is kept in a separate room from the other components.

Further, the storage battery 3, the electric motor 6, the secondary coil 17, and the control circuit 20 are connected to each other by a round cord 22, and a waterproof connector 23 is used at the intermediate portion.

Further, there is a ventilation hole 24 in the upper side of the main body 1, so that when the main body 1 is lifted, the water inside can be quickly discharged through the suction hole 16.

Next, the charger 2 will be explained. An oscillation circuit 25 is installed inside the charger 2, and -
A secondary coil 26 and a core 27 are attached, and the secondary coil 26 is connected to the oscillation circuit 25.

The protrusion 2a has a structure that is fitted into a recess 18a of the coil case 18.

When main unit 1 is placed on charger 2, coil case 1
8 and the protrusion 2a of the charger 2 are fitted together, and the magnet 28 on the bottom of the main body 1 approaches the reed switch 29 of the charger 2, thereby turning on the power of the charger 2.

By causing some of the coils 26 to oscillate due to the oscillation circuit 25,
A current is induced in the secondary coil 17.

The induced current is guided to the control circuit 20 and rectified to charge the storage battery 3.

The bath foaming machine is installed by submerging the main body 1 in a bathtub A after charging the storage battery 3.

At that time, the intake pipe 13 is extended to position the tip above the water surface in the bathtub.

In this state, when the switch 30 is pressed to drive the electric motor 6, water is sucked through the suction port 16 and introduced into the Venturi tube 12.

The water is then throttled by the nozzle portion 12a to increase the flow velocity and is ejected into the bathtub from the spout 1a through the outlet 12b.

At this time, since air is being sucked in through the intake pipe 13, a water stream and air bubbles are ejected.

This increases the pine surge effect, thermal effect, and cleaning effect.

As explained above, since the bath foaming machine of the present invention has the suction port at the lower side of the main body, it has the effect of being able to absorb water even if the bottom suction port becomes blocked.

In addition, since there is a ventilation hole in the upper side of the main body, when the main body is pulled up from the bathtub, the water inside the bathtub is drained from the water intake port quickly, and the inside of the main body can be dried quickly.
