Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for generating a large number of bubbles in a bathtub.

[Conventional technology]

Conventionally, a bubble generator installed outside the bathtub and a bubble injection body installed inside the bathtub were connected via a hose, and air was sent from the bubble generator into the hollow flat box-shaped bubble injection body with numerous injection holes. There are some that spray air bubbles into the bathtub from the injection hole.

There is also a device that integrates the bubble generator and the bubble jet and installs the entire device directly in the bathtub.

[The problem that the idea aims to solve]

The conventional bubble generator described above uses a piston-type air pump as the driving force for feeding air into the bubble injection body. However, in the case of this air pump, since the amount of air was small, it was not possible to sufficiently generate strong bubbles throughout the bathtub. For this reason, a strong vortex cannot be generated in the bathtub, making it impossible to obtain a strong pine surge feeling.

Furthermore, since the temperature of the supplied air is almost the same as room temperature, there are problems in that when the air bubbles hit the body, the body feels cold and the temperature inside the bathtub decreases.

The present invention was developed in view of the problems of the conventional technology described above, and by strongly injecting a large number of bubbles, a vortex is generated in the bathtub to enhance the pine surge effect and prevent the water temperature from decreasing. The object of the present invention is to provide a bubble generating device that does not require the use of air bubbles.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a container 1 having an air inlet 2 and an air outlet 3 with a cradle 8.
A cylindrical body 9 housing a motor 4 is fixed thereon, and a guide plate 10 having an air feed hole 13 communicating with the cylindrical body 9 is built into the pedestal 8. Below this guide plate 10, a cylindrical body 9 housing a motor 4 is fixed. The present invention is characterized in that an air supply device 6 equipped with a fan 5 rotated by a fan 5 is installed via cushioning materials 7 and 16.

[Effect]

By rotating the fan with the rotational drive of the motor, a large amount of high-pressure air that has been heated through the motor is sent to the bubble jetting body, so that bubbles are generated in a whirlpool state in the hot water temperature in the bathtub.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the drawings, reference numeral 1 denotes a sealed cylindrical container, the bottom of which has a plurality of air inlets 2, and the side surface of which has an air outlet 3 protruding.

Inside this container 1, a commutator motor 4 and a fan 5 are installed.
An air supply device 6 consisting of:
Explain in detail.

A cylindrical body 9 housing a motor 4 is erected and fixed on a fixing base 8 which is placed and fixed on a cushioning material 7 such as rubber attached annularly at the lower part of the container 1. A horizontally rotatable fan 5 is housed in a hollow portion of the fixed base 8, which has an open center portion on the lower surface. The rotating shaft 11 of the rotor 10 of the motor 4 is
It passes through the upper plate of the fixed base 8 and is directly connected to the fan 5.

A plurality of air feed holes 12 are arranged in a ring shape in the center of the upper plate of the fixed base 8. This air feed hole 12
may be either a round hole or an annular long hole.

A large number of air outflow holes 13 are formed in the upper part of the cylinder 9.

Note that the upper end of the cylindrical body 9 is also supported by a cushioning material 14.

The fan 5 is for high pressure of 1000 mm to 2200 mm water column, and is rotated by the motor 4 at 28400 rpm (50 cycles).

The present invention has the above-mentioned configuration, and the state of use will be explained next.

When in use, a bubble jet (not shown) placed in the bathtub is connected to the air outlet 3 of the container 1 with a hose. Then, the rotor 1 is driven by the motor 4.
When the fan 5, which is directly connected to the rotating shaft 11, is rotated, external air is sucked into the container 1 from the air inlet 2, and this air is fed into the cylinder 9 through the air feed hole 12 formed in the fixed base 8. be forcibly sent to.

The rotor 10 and stator 15 of the motor 4 are mounted inside the cylindrical body 9.
The heated air (when used at 1900 mm of water column, is heated to 65 to 70 degrees Celsius, and the atmospheric temperature at this time is 23 degrees Celsius and the relative humidity is 40%) is The air flows out into the container 1 from the air outlet 13,
Further, the air is supplied to a bubble injection body through a hose, and is ejected as bubbles from a number of air injection holes provided in the injection body.

As a result of the experiment, when the rated power consumption is 600W,
It had a capacity of 1058 mm of water column x 1.1 m ³ /min (atmospheric temperature 15°C, relative humidity 70%).

Incidentally, if a plurality of guide plates that are curved along the rotational direction of the fan 5 are vertically provided on the lower surface of the upper plate of the fixed base 8, and the tip of each guide plate is directed toward the air feed hole 12,
The air sent from the fan 5 can be rectified and reliably sent to the air sending hole 12.

[Effect of idea]

According to the present invention described above, a large amount of high-pressure air is strongly injected from the bubble injection body by the rotation of the fan 5, so the generated bubbles create a vortex state in the bathtub and produce an ultrasonic phenomenon, and the bubbles are transmitted to the body. This enhances the pine surge effect.

In addition, the air taken into the container 1 is heated by passing between the rotor 10 and the stator 15 of the commutator motor 4, and is injected into the bathtub as it is, so the air bubbles themselves are warm, and therefore the air inside the bathtub is heated. The water temperature will be kept constant or increased.

The rotational vibration of the motor 4 and fan 5 is absorbed by the buffer material 7.
and 14, so no noise is generated, and the commutator motor 4 can provide sufficient power even if it is small, so the entire container 1 can be made smaller.
It will not get in the way even if installed in the bathroom.
