DETAILED DESCRIPTION OF THE INVENTION

[0001]

It is mixed. In the prior art, the purpose of forcibly mixing gas into the spout is mainly to save water and save energy. To explain the principle briefly, although the apparent density of water decreases by forcibly mixing gas into the water discharge, the water discharge speed increases, and depending on the conditions, the actual water discharge amount may be small. This is due to the vigorous spouting.

[0003]

In order to obtain the momentum of the water discharged from the discharge port so as not to cause any trouble in actual use, the volume of the water discharged must be equal to or larger than the volume of the actual water discharged. It is necessary to mix gas. Therefore, if the amount of water discharged increases, the size of a pump or an air compressor for mixing gas increases, and the energy such as electric power required for driving the pump or the air compressor also increases. Therefore, simply sending air to the water channel and mixing it into the water discharge may deviate from the original purpose of energy saving even if water saving is possible.

₁ (m ³ / sec), total area S ₁ (m ² ) of holes where gas and water are in direct contact in the gas-mixed section, average area S ₂ per hole
When (m ² ) is set, the power consumption required for the operation of the gas supply means when the value of the resistance coefficient K defined by K = Q ₁ / (S ₁ · S ₂ ) is variously changed. As shown in FIG. Wherein S ₁ corresponds to _{S a + S b + S c} + S d In an example shown in FIG. 4, S ₂ corresponds to _{(S a + S b + S} c + S d) ÷ 4 in the example shown in FIG. In this embodiment, air is used as the gas to be mixed. The value of K in the first embodiment is variably by changing the value of the adjustable Q ₁ by changing or gas supply means 5 of the gas mixing unit 4.

FIG. 5 shows that when the value of the resistance coefficient K exceeds 3.0 × 10 ⁸ , the amount of power consumption required for the operation of the gas supply means rapidly increases, deviating from the original purpose of energy saving. It turns out that there is a possibility. Therefore, the value of the resistance coefficient K is preferably K = 3.0 × 10 ⁸ or less.

FIG. 5 shows that the value of K is 2.0 × 10 ⁷ to 3.0 × 10 ⁸
It has been found that the power consumption is small and the gas can be efficiently mixed by setting the range. K value is 2.0 × 10 ⁷
If smaller, that is, the value for Q ₁ is smaller than the proper range in the present invention, or if the product of S ₁ and S ₂ is increased, or weakened momentum of the water discharge, water discharge flows back from the nozzle depending on the conditions Inconvenience may occur.

In this embodiment, air is used as the gas to be mixed. However, even if the air contains carbon dioxide or excess carbon dioxide, the tendency of the increase in power consumption with respect to the value of K does not change.

FIG. 7 shows that when the value of u exceeds 5 m / sec, the number of points falls below two, that is, the usability is reduced as compared with the conventional faucet. The main reason for the inconvenience is that the momentum is too strong.

It has been found that when the value of u is less than 1 m / sec, the momentum of spouting becomes too weak, and conversely, the usability drops. As a result of various experiments, it was found that 1 to 5 m / sec is desirable, but a slight difference is more desirable, but 1.2 to 3.5 m / sec or less.

If the coefficient is kept at K = 3.0 × 10 ⁸ or less, it is possible to always mix gas with less power consumption.

In FIG. 9, the on-off valve and the flow control valve are of different constructions. However, the effectiveness of the present invention is still different even if the function of the on-off valve and the flow control valve is one. Absent.

FIG. 10 shows a preferred example of the gas mixing section 4 in the present invention. In FIG. 10, the gas mixing part is a sintered porous body having a hollow pipe shape and is made of metal or resin. In the case where a sintered porous body is used for the gas mixing portion, the voids of each particle constituting the porous body correspond to the nozzle 8 shown in FIG.
