[Industrial application] This invention filters hot water in a bathtub with a filter to keep it clear, keeps the hot water at a constant temperature, and uses fumes to set innumerable bubbles. The present invention relates to a bathtub device capable of jetting.

[0002]

2. Description of the Related Art Circulating hot water to keep it clear,
A bathtub device has been developed which can be kept at a constant temperature for 24 hours. This device keeps the temperature of the hot water constant by the heating means. A filter is also provided to clarify the warm water. Since this device continuously filters hot water to remove foreign matters such as dust and keeps it clean, it is not necessary to replace the hot water in the bathtub. For this reason, it is a water-saving device that allows you to take a bath at any time of day and at any time.

This hot water circulating bath apparatus removes large dust such as hair contained in hot water with a primary filter. 1
The hot water filtered by the next filter uses a natural stone filter to remove fine foreign substances and sterilize.
The primary filter is removably attached to the inlet of the bathtub, and the natural stone filter is built into the casing.

Porous stones are used for natural stone filters. For example, "bourneishi" or granular stone obtained by crushing stones such as barleystone and sintering them into a porous state is also used. This natural stone filter has an excellent effect of efficiently removing ammonia (sweat), protein (dust) and the like that are emitted from the human body. This is because the warm water is clarified under the following conditions. That is, a natural stone filter that circulates warm water provides a comfortable environment for aerobic bacteria to propagate, and bacteria inhabit there. Bacteria
Eat ammonia or protein contained in warm water as food to decompose it. Therefore, sweat and dirt in warm water are effectively removed by the natural stone filter.

The natural stone filter that clarifies the warm water in this state keeps the warm water extremely clear, unlike a filter that simply mechanically removes foreign substances. However, in order for the natural stone filter to effectively clarify the warm water, it is important to keep the habitat of the aerobic bacteria inhabiting comfortably. This is because bacteria clarify warm water. For example, if the operation of the circulation pump is stopped in order to reduce the running cost at midnight when the bath is not bathed, the warm water becomes cloudy and cannot be kept clear. that is,
This is because it is not possible to supply oxygen sufficiently to aerobic bacteria that inhabit the natural stone filter. It is recommended to dissolve a large amount of oxygen in warm water to make the natural stone filter bacteria habitat comfortable.

To achieve this, a large number of bubbles may be jetted into the bath. This is because bubbles of oxygen are dissolved in warm water. To inject bubbles, a fumes is placed at the bottom of the bath. Use a fumarolic material that has fine voids. When pressurized air is supplied to the fumarolic material, when air is ejected from the fine voids, countless small bubbles are ejected in warm water. Further, preferably, the bubbles injected into the warm water also have the effect of generating ultrasonic waves and massaging the human body when bursting in the water. Therefore, not only can the body be massaged by the bubbles, but also the habitat of the bacteria that inhabit the natural stone filter can be improved by using the device that sprays bubbles into the warm water and the device that circulates the warm water and keeps it clear for 24 hours. A synergistic effect can be expected.

[0007]

However, if both a bubble device for injecting bubbles and a circulation device for clarifying hot water are installed inside the bathroom, there is a drawback that the bathroom becomes narrow.
In order to avoid this drawback, the present inventor has developed a structure in which the bubble device is placed on the circulation device. This device
Since the two devices are stacked in two layers, the installation place can be reduced. Therefore, it has a feature that it can be conveniently used by being installed in a small bathroom.

However, although this kind of device can be used very conveniently, since the circulation pump is operated continuously for 24 hours, noise at midnight becomes a problem. The noise level of the circulation pump is quite low, so it is not a problem during the daytime, but in a quiet environment at midnight, extremely low level noise is noticeable. Particularly in a house where the bathroom is adjacent to the bedroom, how to reduce the noise level of the circulation pump is very important. In particular, the noise generated from the circulation pump has a relatively low frequency.
Noise with a relatively low frequency is difficult to be easily insulated like noise with a high frequency. High frequency noise can be isolated with a light sound insulation material such as glass wool. However, low-frequency noise is very heavy, such as lead and concrete, and cannot be reduced unless the sound is shielded.

The present invention was developed to solve this drawback, and the important purpose of the bathtub apparatus of the present invention is to have an extremely simple structure, reduce the noise level, and be comfortable in a clear environment at midnight. Another object of the present invention is to provide a bathtub device that can be used in any of the above, and sprays bubbles into the bathtub to keep the warm water clear.

[0010]

The bathtub device of the present invention is
In order to achieve the above-mentioned object, the following configurations are provided. The bathtub device is connected to the bathtub 1 via the circulation path 2 to forcibly circulate the hot water in the bathtub 1, and the circulation path 2 of the hot water circulated by the circulation pump 3 to connect the hot water to the hot water.
A filter 5 for holding the fining, the heating means 4 for warming the hot water of the bathtub 1 to a predetermined temperature, and pressurized to jet member 9 disposed in the bath tank 1 a jet fan 6 for injecting air Prepare

Furthermore, bathtub apparatus of this invention accommodates the circulation pump 3 and the full Iruta 5 in the hot water circulation casing 7. The blower fan 6 is housed in a blower casing 8 which is a separate case from the hot water circulation casing 7. Also,
The hot water circulation casing 7 is mounted on the fumarolic casing 8. That is, in the bathtub device of the present invention, the fumarolic casing 8 containing the fumarolic fan 6 is also used as a mounting table for reducing the noise level.

[0012]

In the bath apparatus of the present invention, the hot water circulation casing 7 containing the circulation pump 3 is placed on the fusible casing 8. The fumes casing 8 on which the hot water circulation casing 7 is mounted incorporates the fumes fan 6 driven by a large motor. The blower fan 6 is driven by a motor having a considerably large value of 100 to several 100 W. This is because a large amount of pressurized air is supplied to the fumarolic material 9. Therefore, the motor of the blower fan 6 is considerably heavy, and in order to vibrate it,
Requires a lot of energy. In other words, by vibrating this, the energy of vibration of the circulation pump 3 is well absorbed. The hot water circulation casing 7 containing the circulation pump 3 is mounted on the fumarolic casing 8. In this state, the vibration of the circulation pump 3 is transmitted to the floor of the bathroom via the fumes casing 8. When the vibration of the blower casing 8 is reduced by the built-in blower fan 6, the vibration of the circulation pump 3 is reduced by the blower fan 6 and is transmitted to the floor.
Therefore, the bathtub device for injecting air bubbles into the bathtub 1 of the present invention to keep the warm water clear is the noise level due to the vibration, especially the unpleasant vibration transmitted to the floor of the bathroom, by the air blower casing 8 having the blower fan 6 built therein. Can be reduced. Further, the bath device of the present invention does not use any special member in order to reduce the noise level due to the vibration of the circulation pump 3. Effectively using some of the parts used together,
Reduce noise level. Therefore, no extra cost is required to reduce the noise level.

EFFECTS OF THE INVENTION The bath device of the present invention, which sprays air bubbles into the bath to keep the warm water clear, supplies a large amount of oxygen to the warm water to allow bacteria inhabiting the filter to live in a comfortable environment. The warm water, which contains a large amount of oxygen, effectively keeps the filter water clean. Also,
Bubbles sprayed into warm water massage the human body.

[0024] Further noteworthy features of this invention is, thus, utilizes a jet fan that injected into the hot water, and a jet casing incorporating this into the sound insulating member, the depth
It is to reduce the noise level of the circulation pump that operates even at night . The circulation pump for forcibly circulating hot water is continuously operated for 24 hours in order to supply oxygen to aerobic bacteria and keep the hot water clear. For this reason,
Even if the circulation pump is designed with a considerably reduced noise level, it vibrates the floor of the bathroom at midnight when the surroundings are extremely quiet, and this is transmitted to the bedroom and becomes annoying noise. If the circulation pump can be stopped at midnight, this is not a problem. This is because the noise level of the circulation pump can be reduced to the extent that it is not disturbing during the daytime. However, when stopping the operation of the circulation pump in the middle of the night, oxygen is not supplied to the bacteria aerobic inhabiting filter. When the habitat of bacteria deteriorates, they cannot effectively clarify the warm water. Then, the warm water becomes cloudy white and cannot be kept clear in a short time. Unfortunately, if warm water becomes cloudy, it takes a very long time to clarify it. This is because the filter does not physically filter the warm water to clarify it. The warm water becomes cloudy because the bacteria that inhabit the filter have died and the fining effect has disappeared, so it takes a considerable number of days before it breeds. Therefore, in the bathtub device that keeps the warm water clear, the circulation pump must be continuously operated even in the quiet midnight.

In particular, the noise of the circulation pump is eliminated
It is low frequency sound that is difficult to reproduce. High frequency
Noise is the sound insulation of plastic foam, glass wool, etc.
Effective sound insulation with wood. However, low frequency noise
The sound is almost muted even if such a sound insulation material is used.
Absent. The noise level increases as the frequency decreases.
If the energy is the same, the amplitude will increase.
It High-frequency noise causes amplitude even if the energy is large.
Is small and the number of vibrations per second is large. Fast with small amplitude
High frequency noise that vibrates frequently
Can be effectively silenced with sound insulation materials such as. However, low laps
It is extremely important that the noise of wave number is effectively transmitted through the sound insulation material.
Very difficult. The circulation pump operated at midnight vibrates,
Generates low frequency noise. Low frequency vibrations in the bathroom
It is transmitted to the bedroom through the floor of the house, and it feels like a quiet midnight
It makes a lot of noise. To effectively insulate low frequency noise
Requires the use of very heavy sound insulation such as lead.
It Heavy sound insulation uses a lot of energy to vibrate
Since it is necessary, it effectively shields low frequency noise. This
Therefore, it is not comparable to sound insulation materials such as plastic foam.
In order to be sufficiently expensive, and to insulate sound sufficiently
Needs to use a large amount of heavy sound insulation,
There is a drawback that the weight becomes extremely heavy.

The bath device of the present invention has a circulation pump built-in.
Do not install the hot water circulation casing directly on the floor,
The fumarolic casing containing the fan
It has a unique structure that is installed on the floor of the bathroom to improve the noise level.
Reduce significantly. Especially, it effectively shields low frequency noise.
Make a sound. When the bathtub of this structure is installed, in order for the circulation pump to vibrate the floor of the bathroom, it is necessary to vibrate the fumarolic casing, which is a mounting table. The fumarolic casing contains a large capacity and heavy fumarolic fan. Therefore, vibration is prevented in the fumarolic casing by the built-in fumarolic fan. This is because a large amount of energy is required to vibrate the heavy blower fan. That is, in the bathtub device of the present invention, the vibration of the circulation pump is effectively absorbed by the fusible casing containing the heavy fusible fan to reduce the noise level. The fumarolic fan is not built into the fumarolic casing to absorb vibrations. It is a necessary component to generate bubbles in warm water. Further, the fumarolic fan does not continuously rotate. Only drive when you need to take a bath. For this reason, the noise of the jet fan is not really care. The bathtub device of the present invention massages the human body, and also uses a fumarolic fan that supplies oxygen to aerobic bacteria that inhabit the filter, and a fumarolic casing that incorporates it into the vibration absorbing member of the circulation pump,
Reduce noise level.

By the way, in the experiment conducted by the present inventor, the noise level could be reduced by 2.8 dB as described below by placing the hot water circulation casing on the fusible casing. This can be reduced by 48% in terms of vibration energy. However, noise was measured under the following conditions. The background noise was set to an environment of 30 dB or less, and a sound level meter having a measurement range of A range was installed at a position 1 m away from the apparatus for measurement. The bathtub device operated the circulation pump to circulate the hot water, and the operation of the fumarolic fan was stopped. Place the hot water circulation casing directly on the floor ………………………………………………………………………………………………………………………………………………………………. … 64.3 dB

As described above, the bathtub device of the present invention has an extremely simple structure in which the fuming casing containing the fuming fan is also used as the mounting table, and the noise level of the circulation pump can be halved, and it can be used comfortably in a quiet midnight. Achieve the features you can.
