DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view showing the structure of the apparatus, FIG. 2 is an enlarged sectional view of a cleaning liquid supply means, and FIG. 3 is an enlarged sectional view of a water flow pump means.

In FIG. 1, reference numeral 10 denotes, for example, a tap for water supply as a water source for supplying running water at an appropriate water pressure. Numeral 20 denotes a water jet pump means, which jets the water from the water source (faucet) 10 and mixes a washing liquid 31 described later into the jet water by suction.
It is sent to a delivery pipe 40 described later. This water flow pump means 2
At 0, at the stage when the cleaning liquid 31 is mixed with the flowing water to be jetted, at least a part of the flowing water (hereinafter also referred to as cleaning flowing water) mixed with the detergent as the cleaning liquid 31 becomes foamy. Hereinafter, foaming the washing water using the mechanism and action (suction force) in the water jet pump means 20 is also referred to as first foaming means. The reference numeral 11
Is a pipe as a supply connection pipe for appropriately connecting the faucet 10 as a water source and the water flow pump 20, and is provided with a commercially available connection member.

Reference numeral 30 denotes cleaning liquid supply means for supplying the cleaning liquid 31 to the water flow pump means 20. From the cleaning liquid supply means 30, the cleaning liquid 31 is sucked into the water flow pump means 20 according to the suction force by the negative pressure generated by receiving the supply of the running water by the water flow pump means 20. This suction power increases as the flow rate and volume increase. Cleaning liquid 31
May be a solution depending on the application. For example, an appropriate detergent solution is used for cleaning purposes.

In FIG. 2, a cleaning liquid supply means 30 includes a container 30 having a vent 32 communicating with the atmosphere, a cleaning liquid 31 in the container 30, one end of which is immersed in the cleaning liquid 31, and the other end of which has a suction port 21 of the water pump 20. And a supply pipe 33 as a cleaning liquid supply pipe connected to the cleaning liquid supply pipe. In the middle of the supply pipe 33 serving as the cleaning liquid supply pipe, an intake hole 51 (hereinafter, referred to as a first port) serving as an air mixing means for mixing air into the cleaning liquid 31 sucked by the suction force of the water flow pump means 20.
(Also referred to as air mixing means). in this way,
By mixing air into the cleaning liquid 31 before mixing the cleaning liquid 31 into the jetted water of the water jet pump means 20, foaming can also be performed when the cleaning liquid 31 is jetted in the water jet pump means 20. Can be.

The intake hole 5 as the first air mixing means
1 is, for example, one having the same mechanism and operation as the above-mentioned water flow pump means 20, and
The outside air, that is, the air may be sucked from the suction hole 51 corresponding to the suction port 21 of the above, and may be mixed with the washing liquid 21 being sucked up. The intake hole 5 shown in this embodiment
1 is provided in the container 30, but is not limited to this.
It may be provided at an appropriate position of the supply pipe 33 outside the container 30. However, if the cleaning liquid 31 flows backward due to a decrease in suction force by being provided in the middle of the supply pipe 33 extending into the container 30, for example, when the cleaning liquid 31 in the supply pipe 33 is sucked in at the end of the detergent spraying operation, etc. Even if leaking from the hole 51, the container 3
0 can be collected.

Referring again to FIG.
A delivery pipe 40 of an appropriate length is connected to the downstream side of.
In the delivery pipe 40, at appropriate intervals from the upstream side to the downstream side, an intake hole 52 as a second air mixing means,
An intake hole 53 as third air mixing means, a mesh passage section 60 as second foaming means, and a mesh passage section 70 as third foaming means are sequentially arranged. Less than,
In FIG. 3, an intake hole 5 as a second air mixing means is shown.
Second, the intake hole 53 as a third air mixing means will be described.

The suction holes 52 and 53 serving as the second and third air mixing means are provided on the side wall of the delivery pipe 40 as appropriate and provided as an air passage for sucking outside air, that is, air into the pipe. These suction holes 52 and 53 are provided in the water flow pump means 20.
A negative pressure in the pipe caused by a strong water flow spouted vigorously from the pipe causes air outside the pipe to be sucked, so that the air suction force by the negative pressure acts on the side close to the water pump means 20, ie, the delivery pipe. It is arranged upstream of 40.

Although not shown, a belt-like ring is fitted to the intake holes 52 and 53 as an air-conditioning means capable of appropriately adjusting the amount of air to be sucked. By shifting the position of the band-shaped ring, the number of air-permeable intake holes may be increased or decreased.
In the first embodiment, since the water source 10 is a water supply in which the maximum flowing water amount and the water pressure are almost constant, the water flow pump means 20 and the first to third air according to the flowing water amount and the tap water pressure of the water source 10 are used. Adopts mixing means. For example,
The diameter of the hole is formed. Therefore, the air adjusting means as described above is not always necessary.

Referring to FIGS. 1 and 3, mesh passing portions 60 and 70 as second and third foaming means will be described. Mesh passing portions 60 and 7 as second and third foaming means
0 is already the first to third air supply means 51, 52,
This is a means for foaming by passing a mesh, that is, a mesh, into the air / washing water in which air is mixed in and partially foamed by 53.

In the mesh passage section 60 as the second foaming means shown in the figure, a small-diameter cylinder 61 is disposed in the delivery pipe 40, and a mesh or net is formed inside and outside the cylinder of the small-diameter cylinder 61. The configuration has been applied. When the air / washing water passes through the nets inside and around the small-diameter cylindrical body 61, the mixed air and the washing liquid 21 promote foaming. In this example, by using the small-diameter cylindrical body 61, not only the washing running water is allowed to pass through the net, but the air
The efficiency of the foaming action is improved. However, it is of course also possible to simply adopt, for example, a configuration of passing through a multi-layered net.

Mesh passing portion 7 as third foaming means
Numeral 0 is disposed on the downstream end side of the delivery pipe 40, and is configured to simply allow the air / washing water to pass through the net 72. Using a finer mesh than the mesh of the mesh 62 of 60, the foam air-washing water generated and flowing down in the mesh passage section 60 as the second foaming means is converted to finer foam. It is a means to send out. In this embodiment, the second and third foaming means using a mesh are used. However, a plurality of foaming means (not shown) each having a gradually smaller mesh may be appropriately disposed.

Since the cleaning liquid foaming apparatus of this embodiment is configured as described above, after air is mixed into the cleaning water mixed with the cleaning liquid, the cleaning water mixed with the air, that is, the air / washing water is mixed. Can be efficiently and sufficiently foamed. In addition, by using water supply as running water supplied at an appropriate water pressure, foaming washing running water can be obtained extremely easily.

[0026]

According to each of the first to tenth aspects of the present invention, it is possible to efficiently and sufficiently bubbling the washing water containing air, that is, the air / washing water. In addition, by using tap water as running water supplied at an appropriate water pressure, it is possible to obtain a desired foaming and washing running water by simply adjusting a faucet, for example, by turning the faucet to a maximum water pressure. It is not necessary to provide adjustment equipment, the number of components is small, the structure and operation are simple,
An inexpensive cleaning liquid foaming apparatus can be provided.
