Abstract

PROBLEM TO BE SOLVED: To provide a washing device capable of preventing the detergent liquid from coming into the feed tube even if the water has flowed backward due to accidental pressure down of the water in the feed tube, without using any driving device to eject the water by utilizing the jet water flow and provide also a mixing device to mix up the jet water and the detergent liquid. SOLUTION: Ejection of a jet water 4 stops when the water flows backward due to the pressure down in a feed tube 1. Flow of the water and the detergent liquid are absolutely kept apart when the jet water 4 has stopped as a mixing device 5 is feeding the detergent liquid so as to meet it with the jet water 4 on the point it was ejected out from a nozzle 2. Thus the detergent liquid wound never come into the feed tube 1 even if the water has flowed backward.

BEST MODE FOR CARRYING OUT THE INVENTION First, in the present invention, one idea is changed. That is, according to the conventional idea, in order to obtain a jet stream of a solution, first, water and a detergent must be mixed to form a solution, and then the solution must be jetted from a nozzle to obtain a jet stream of the solution. . The present invention is based on the idea of revising the idea, first jetting water from a nozzle to create a jet stream of water, and then mixing a detergent with the jet stream of water to obtain a jet stream of a solution. is there.

Embodiment 1 1 is a block diagram of a cleaning device using a jet water flow according to a first embodiment of the present invention. In the figure, 1 is a water supply pipe, 2 is a nozzle, 3 is a hose that connects the water supply pipe 1 and the nozzle 2 and supplies water from the water supply pipe 1 to the nozzle 2, 4 is a jet water flow ejected from the nozzle 2, and 5 is This is a mixing device for mixing the jet water stream 4 and the detergent.

The mixing device 5 comprises a detergent container 6, a thin tube 7 and a space 8 through which the jet water flow 4 passes. Thin tube 7
Is connected to the inside of the detergent container 6, and the lower end of the thin tube 7 is arranged directly above the jet water flow 4. The space 8 is a space portion, and the thin tube 7 is a pipe portion.

Next, the operation will be described. When the water supply from the water supply pipe 1 is started, the water passes through the hose 3 and the nozzle 2
Is supplied to. Then, the pressure inside the nozzle 2 becomes substantially equal to the pressure in the water supply pipe 1, and the jet water flow 4 of water is ejected from the nozzle 2.

The detergent container 6 contains a liquid detergent. This detergent flows in from the upper end of the thin tube 7 connected to the interior of the detergent container 6 and drops downward from the lower end. On the other hand, the jet water flow 4 ejected from the nozzle 2 passes through the space 8. At this time, since the detergent is dripped from the lower end of the thin tube 7 arranged immediately above the downstream position of the jet water stream 4, the jet water stream 4 and the detergent merge and are mixed.

Here, since there is nothing that hinders the motion of the jet water stream 4, the kinetic energy of the jet water stream 4 is not impaired. As described above, according to the first embodiment, the jet water flow 4 of water can be mixed with the detergent to obtain the jet water flow 4 of the detergent solution. Further, it is possible to obtain the mixing device 5 for mixing the water of the jet water stream 4 and the detergent without impairing the kinetic energy of the jet water stream 4.

Next, the case where the pressure of the water supply pipe 1 is lowered and the water flows backward during the use of the cleaning device will be described. When the backflow occurs, jetting of the jet water flow 4 is stopped, and the water reaching the nozzle 2 flows into the water supply pipe 1. The detergent mixes with the water after jetting from the nozzle 2 as the jet water flow 4, so the jet water flow 4
The suspension of the water completely disconnects the detergent and the water flow. Therefore, even if the backflow of water occurs, the detergent does not flow into the water supply pipe together with the backflow of water.

As described above, according to the first embodiment, the jet water flow 4 that does not require a drive unit for ejecting the jet water flow 4 and prevents the detergent from flowing into the water supply pipe 1 is provided. The used cleaning device can be obtained.

Embodiment 2 FIG. Second Embodiment FIG. 2 is a configuration diagram of a mixing device showing a second embodiment of the present invention. In the figure, the same or corresponding parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 9 is a sprayer arranged to spray the detergent contained in the detergent container 6 toward the space 8.

Next, the operation will be described. The jet water flow 4 is passed through the space 8 while the sprayer 9 sprays the detergent contained in the detergent container 6 toward the space 8. When the jet water flow 4 passes through the space 8, it draws in the surrounding air by friction and takes it into the water flow.
The air taken in contains the sprayed detergent in the form of fine particles.

Therefore, when the jet water stream 4 passes through the space 8, the detergent is taken into the inside of the water stream, and the jet water stream 4 and the detergent are mixed. At this time, since there is nothing that hinders the movement of the jet water stream 4, the kinetic energy of the jet water stream 4 is not impaired.

Next, the operation will be described. Since the jet water flow 4 passing through the space 8 has a very high flow velocity, the internal static pressure becomes lower than the pressure of the surrounding atmosphere. Therefore, a pressure difference is generated at both ends of the detergent supply pipe 10. Due to this pressure difference, the detergent contained in the detergent container 6 passes through the detergent supply pipe 10 and flows into the jet water flow 4.
By flowing this detergent into the jet water stream 4,
Jet water stream 4 and detergent mix.

At this time, the obstacle that impedes the movement of the jet water flow is the collision plate 11.
It doesn't exist except. The collision plate 11 is an element necessary for obtaining a flat jet water flow. That is, the kinetic energy of the jet water flow is not further impaired by the detergent mixture.

As described above, according to the fourth embodiment,
It is possible to obtain the mixing device 5 for mixing the water of the jet water stream 4 and the detergent without impairing the kinetic energy of the jet water stream 4.
