Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a Yunaka foaming machine that generates water flow and bubbles in a wound in a bathtub, thereby producing a massage effect, a heating effect, and a cleaning effect.

Embodiments of the present invention will be described below with reference to the drawings. 1st
As shown in the figure, the main body 1 is attached to the wall of bathtub A or is used completely submerged in water;
As shown in FIG. 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 which has a sealed structure by thermal welding, and is installed in a part of the main body 1. Further, an electric motor 6 is built into the main body 1, and the dewing machine 6 is attached to a chassis 7 and sealed with a cover 8 and sealing materials 9, 9. The cover 8 has a substantially triangular planar shape, and wires are connected in three spaces between the cover 8 and the electric motor 6, eliminating gaps in the pond part to increase the strength of the cover 8, and at the same time increase the amount of air inside. Care has been taken to minimize the expansion and contraction so that the sealing performance does not deteriorate.
A casing 10 is provided on the opposite side of the chassis 7 from the electric motor 6.
is attached to form a spiral chamber between it and the chassis 7. A honeycomb 11 is attached to the tip of the shaft of the electric motor 6, and the honeycomb 11 rotates in the center of the casing 10 to suck water from the bottom of the casing 10 to form a spiral pump. The water flow generated in the casing 10 is guided to the Venturi tube 12. The water flow constricted by the nozzle portion 12a of the Venturi tube 12 increases its flow velocity and is discharged from the outlet 12b. At that time, air is sucked in from the intake part 12c connected to the intake pipe 13,
A water stream and air bubbles are ejected from the outlet 12b. The water stream and air bubbles are ejected from the spout la provided on the front surface of the main body 1.The intake pipe 13 is formed of a plurality of pipes 13a with different diameters and has a structure that can be expanded and contracted. Make it stick out and 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 the suction rows 6 at the bottom and sides communicating with the inside 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. Also,
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. Next, the charger 2 will be explained. An oscillation circuit 25 is installed inside the charger 2, and a primary coil 26 and a core 27 are installed inside a part of the charger 2 that has a flared projection 2a. Coil 26 is connected to oscillation circuit 25.

The protrusion 2a has a structure that is fitted into a recess 18a of the coil case 18. The shapes of the protrusion 2a and the recess 18a are designed so that they fit together in a tapered manner. Main body 1
When set on the charger 2, the coil 2 case 18 and the protrusion 2a of the charger 2 are iron-coupled, and the magnet 28 on the inner bottom of the main body approaches the lead switch 29 inside the charger 2, so that the charger 2 The power is turned on.

When the primary coil 26 oscillates by the oscillation circuit 25, "
Three currents are induced in the secondary coil 17. The yield current is led through the control circuit 201 to charge the storage battery 3 which is rectified. The bath foaming machine is installed by submerging the main body 1 in the 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 operated to drive the electric motor 6, water is sucked in through the suction port 16 and guided into the Venturi pipe 12.Then, the water is throttled by the nozzle portion 12a, increasing the flow velocity, and passing through the outlet 12b into the bathtub from the spout la. At this time, since air is sucked in through the intake pipe 13, a water stream and air bubbles are ejected.This provides a massage effect, a heating effect, and a cleaning effect.As explained above, the present invention The Yunaka Foaming Machine consists of the main unit and a charger, so when you use it, you can take just the main unit into the bathroom, and since the main unit is powered by a storage battery, there is no need for a power cord, making it easy to use. It has an unprecedented effect.

In addition, the charger does not receive input unless it is in competition with the main unit, does not consume unnecessary power, and is safe. There is also no switch on the surface of the charger, which eliminates the negative effects of water, making it extremely easy to use. there is.
