Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a hot flash prevention device in a bathroom or the like.

(Exposure) Conventional technology In the past, an air pressure channel was interposed between the bathtub body and a compressor installed outside the bathtub body, and air was forced into the bathtub through the air pressure channel. There are bubble-generating bathtubs designed to eject and mix air bubbles into the body's bath.

Such bubbles can generate ultrasonic waves to stimulate the bather's body and provide a massage effect.

Focusing on this man-lige effect, various types of bubble-generating bathtubs have been developed, and one form of this is that the capacity of the compressor drive motor is made variable. There are some that allow the amount of air bubbles mixed into the tank to be adjusted.

However, such bubble-generating bathtubs still have the following problems to be solved.

That is, the body of the bather is significantly activated by the massage effect of the bubbles described above, but if the bather is an elderly person or a child, or if the bather is not in good physical condition, You may feel hot in the changing room afterwards.

In particular, if such hot flashes occur while taking a bath, it can be life-threatening.

Therefore, in recent years, devices have been proposed for blowing air toward the face of a bather in a bathroom to prevent hot flashes.

(c) Problems to be Solved by the Invention However, such hot flash prevention devices still have the following problems to be solved.

In other words, the drive device used in the hot flash prevention device described in section 2 has a constant air volume or can be switched between two or three stages, so it supplies the bather with the optimal air volume that suits the bather. Therefore, it was not possible to achieve a sufficient Nobose effect.

Furthermore, since the air volume is constant, the nature of the wind is simple and artificial, and it is not possible to create a natural breeze such as a so-called breeze, and it is not possible to provide bathers with a refreshing or refreshing feeling.

An object of the present invention is to provide a hot flash prevention device for a bathroom or the like that can solve the above problems.

(2) Means for Solving the Problems The present invention provides an air outlet capable of ejecting air toward the human body in a bathroom, etc., and connects the air outlet to a compressor to drive the compressor. Embodiments The present invention will be specifically described below based on embodiments shown in the accompanying drawings.

In FIGS. 1 and 2, A indicates a bubble-generating bathtub according to the present invention, and the bubble-generating bathtub A is disposed near the bathtub body 1, and the inside of the bathtub body 1 blows out air to create bubbles. The compressor 2 is equipped with a compressor 2 that generates .

In this structure, two foot-side jet nozzles 3, two dorsal-side jet nozzles 4, and two ventral-side jet nozzles 5 are attached to the front wall, rear wall, and side wall of the bathtub body 1, respectively.

7 and 8 are collectively connected to a main air pipe 9, and the main air pipe 9 is further connected to the compressor 2.

Further, the compressor sofa 2 is connected to be drivable by a compressor driving motor H.

Accordingly, we have developed a method for preventing hot flashes in bathrooms, etc., which is characterized in that the number of revolutions of the motor for driving the compressor is controlled by frequency conversion using an in-hark, and the amount of air hitting the human body can be adjusted. It is related to the device.

(E) Actions and Effects Bathers operate the compressor drive motor ○
When N is selected, the rotation speed of the compressor driving motor can be changed steplessly from low speed to high speed by the action of the inverter having a frequency conversion function.

Therefore, the rotation speed of the compressor drive motor can be varied steplessly and periodically, creating a natural breeze such as a gentle breeze, giving bathers a refreshing or refreshing feeling. .

In addition, since the rotation speed of the compressor drive motor can be changed steplessly, the view and strength of the wind for bathers can be subtly adjusted, and the air volume can be changed smoothly. Therefore, it is possible to provide detailed hot flash prevention effects tailored to the gender, age, physical condition, etc. of the bather.

4 When the tassel l1 is driven, the compressor 2 is activated and compressed air can be ejected into the bath within the bathtub body 1, generating air bubbles.
By applying the bubbles to desired parts of the bather's body, such as the feet, back, abdomen, etc., the manosage effect can be achieved.

In addition, as shown in FIGS. 1 and 2, the bathtub body l has
Hot flash prevention device B is installed.

That is, in this embodiment, such a hot flash prevention device B,

Next, the operation of the bubble generating bathtub 8 having the configuration described in section 2 will be described, particularly the control of the amount of hot flash air and the amount of bubbles ejected by controlling the compressor drive motor 11.

The bather first operates the mode switching switch provided on the operation panel 15 to change the main air pipe 9 to the branch air pipes 6 and 7.
・After that, turn the operating switch of the compressor drive motor 1L on the operation panel 15 to 0.
When N is selected, the rotational speed of the compressor sole drive motor 11 of the compressor 7 can be changed steplessly from low speed to high speed by the action of the in-hark 12 having a frequency conversion function.

Therefore, by steplessly and periodically changing the rotation speed of the compressor drive motor 11, it is possible to create a natural breeze such as a breeze, giving a refreshing or refreshing feeling to bathers. I can do it.

Further, since the rotation speed of the compressor drive motor 11 can be changed steplessly, the amount and strength of the airflow to the bather can be finely adjusted, and the airflow amount can be changed smoothly.
