Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a shower device for bathing that generates fine bubbles.

[Background technology]

BACKGROUND ART Shower devices that have been used in the past include those that eject water straight from a shower nozzle, and foam shower devices that eject bubbly water by entraining air in shower water. The former straight type shower device has a high water pressure and a high flow rate of ejected water, so it is highly effective for cleaning and rinsing, but there is a problem in that the water that bounces back is scattered around. Furthermore, if the flow rate of the jet water is increased in order to increase the cleaning effect, there is also the drawback that the stimulation to the body becomes too strong, causing a painful sensation. On the other hand, the latter type of foam shower device has a structure that draws in air with the flow of water and discharges mixed water with bubbles, so that even if the foamy water hits the body, the water that bounces back will be scattered around the body. Although it is designed to prevent it from scattering,
There was a problem in that the flow rate of water decreased when air was drawn in, so a great cleaning effect could not be expected.

[Purpose of the invention]

The present invention was made in view of the technical background described above, and its purpose is to provide foamy water that does not slow down the water flow rate, can be expected to have a great cleaning effect, and has less scattering. An object of the present invention is to provide a shower device capable of discharging.

[Disclosure of the invention]

The shower device of the present invention is a shower device for bathing, and includes a gas dissolving device 1 for pressurizing and dissolving gas in water, and a device for reducing the pressure of water in which the gas is dissolved to discharge fine bubble water. A bubble generating nozzle 2 is connected to the air bubble generating nozzle 2 by a pressure-resistant hose 3. In the bubble generating nozzle 2, the dissolved water in which the gas has been dissolved in the gas dissolving device 1 is converted into fine bubble water and discharged, so that the discharged water scatters less and does not cause pain to the skin. It gives a moderate amount of irritation and can be expected to have a cosmetic effect, and since the water is pressurized by the gas dissolving device 1 and depressurized by the bubble generating nozzle 2, the flow rate of the discharged water does not become small, and the It can discharge water at a high flow rate and is highly effective for cleaning or rinsing.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, the shower device includes a gas dissolving device 1 directly connected to a water faucet 4, a pressure hose 3, and a bubble generating nozzle 2. The gas dissolving device 1 forcibly mixes gas (air) into water (or hot water), pressurizes this gas-liquid mixed water, and dissolves the gas in the water. In this way, the gas-dissolved water produced by the gas-dissolving device 1 is sent to the bubble-generating nozzle 2 by the pressure-resistant hose 3 without reducing the water pressure. The bubble generating nozzle 2 consists of a pressure reducing section 5 and a shower head 6, and the pressure reducing section 5 has an internal mechanism as shown in FIG. That is, an orifice 9 having a hole 8 smaller than the inner diameter of the flow path 7 is built in the flow path 7 in the pressure reducing part 5, and the pressurized water sent from the pressure hose 3 passes through this orifice 9. The pressure is now reduced. However, when pressurized water is directly discharged from the orifice 9 into atmospheric pressure, the pressure is rapidly reduced, and fine bubbles cannot be obtained because there is no nucleus for bubble generation. For this purpose, a buffer chamber 10 is provided in front of the orifice 9, and the floating body 11 is delivered with an appropriate amount of play within the buffer chamber 10, and is stopped by a mesh-like stopper 12 so that the floating body 11 does not come off. Therefore, the fast-flowing water flow coming out of the orifice 9 collides with the floating body 11 to cause cavitation, causing bubbles to be deposited. Further, the water pressure is not released all at once to atmospheric pressure, but is released in two stages by the orifice 9 and floating body 11, making it difficult for the precipitated bubbles to collect. When the pressurized water exits the stopper 12, it becomes fine bubble mixed water containing fine bubbles, and is vigorously discharged from the nozzle hole 13 of the shower head 6, ensuring the same discharge amount, discharge speed, and pressure as a normal shower nozzle. Generally, the cleaning effect of a shower is related to the speed of discharged water, and the higher the speed, the greater the cleaning power, but the shower device of the present invention does not involve the water flow entraining air midway through, but dissolves air bubbles from the beginning using the gas dissolving device 1. Because of this, the flow rate is not reduced, and a discharge rate equivalent to that of a straight type shower device can be obtained, making it possible to obtain high cleaning power. On the other hand, the physical sensation of pain and pressure is thought to be related to the density of kinetic energy, and the kinetic energy per unit volume is generally expressed as E = 1/2Mv ² (M mass per unit volume, i.e. density, v flow velocity). Therefore, at the same flow rate, aerated water has a lower density, so the kinetic energy density E is also lower, and as a result, even if the flow rate is higher than in a normal shower and the cleaning power is increased, it will not cause irritation. By using less amount, you can get a milder shower on your skin. Furthermore, it is natural that there is less water scattering compared to a straight type shower that uses only water.

In the above embodiment, the gas dissolving device 1 is directly connected to the water faucet 4, but if you want to discharge hot water containing fine bubbles from the bubble generating nozzle 2, the gas dissolving device 1 can be connected to a hot water tank, water heater, etc. can be connected to.

〔Effect of the invention〕

As described above, the present invention provides a gas dissolving device for pressurizing and dissolving gas in water, a bubble generating nozzle for reducing the pressure of water in which the gas is dissolved, and discharging fine bubble water, and a pressure resistant hose. Since the bubble generating nozzle is connected to the bubble generating nozzle, the dissolved water in which the gas is dissolved in the gas dissolving device is converted into fine bubble water and discharged, so that there is less scattering of the discharged water and it does not cause any pain to the skin. It provides a moderate amount of stimulation and can also be expected to have cosmetic effects. Moreover, since the water is pressurized by the gas dissolving device and depressurized by the bubble generating nozzle, there is no need to reduce the flow rate of the discharged water, and the water can be discharged at a high flow rate, making it highly effective for cleaning or rinsing. . In addition, since the bubble generation nozzle and the gas dissolving device are connected with a pressure-resistant hose, the pressure of the pressurized dissolved water is not reduced on the way to the bubble generation nozzle, which prevents fine bubbles from forming in the bubble generation nozzle. This has the effect of ensuring that the occurrence is caused by precipitation.
