開示されたものがある。2. Description of the Related Art Conventionally, there has been known a foam generator in which a foam for washing is generated by foaming a washing liquid, and the foam is caused to flow out to a washing place.
There are those disclosed in 275678 and JP-A-8-71023.
【０００３】これらの泡発生器は、洗浄液が供給される
液体供給管のほかに、空気が供給される空気供給管とを
必要としている。[0003] These foam generators require an air supply pipe to which air is supplied in addition to a liquid supply pipe to which a cleaning liquid is supplied.

要であり、この点からもコストアップとなっている。Therefore, in order to use the conventional bubble generator, it is necessary to provide a pipe between the liquid supply pipe and the air supply pipe, so that the piping work is troublesome and the number of parts is increased. The cost has increased. Further, an air pump or a compressor for sending air is required, which also increases costs.

ことが困難になる。In the case where the cleaning liquid is caused to directly collide with the mesh body as in the compressor disclosed in Japanese Patent Application Laid-Open No. Hei 7-275678, the rate of bubbles generated by the collision is low, and sufficient bubbles are generated. To do so, a large number of meshes must be arranged towards the outlet of the foam. In addition, it is difficult to reduce the size of the bubble generator by using a large number of nets.
【０００６】そこで本発明は、空気を供給するための空

And a liquid discharge hole for squeezing the liquid supplied through the liquid supply pipe and discharging the liquid into the main body case, and a main body case for sucking air outside the main body case into the main case by the flow of the liquid discharged from the liquid discharge hole. And a perforated plate having a number of small holes formed therein, and a mesh disposed between the perforated plate and the bubble outlet. With.

できる。Therefore, when the liquid discharged from the liquid discharge hole flows through the inside of the main body case, the flow causes air outside the main body case to be sucked into the main body case from the air suction port. Therefore, by using this foam generator, it is not necessary to provide an air supply pipe, and the cost can be reduced.

くなり、泡発生器が小型化される。[0009] The liquid discharged from the liquid discharge holes collides with the perforated plate, and the film of the colliding liquid covers the small holes of the perforated plate. In each small hole, the small holes are covered by the pressure difference between the front and rear of the perforated plate. The liquid film swells and bubbles form. Therefore, by providing a perforated plate, the generation rate of bubbles increases. The bubbles generated in the perforated plate flow away from the perforated plate to the reticulated body side, and the bubbles passing through the reticulated body are set to be approximately the same as or smaller than the average diameter of the bubbles flowing through the reticulated mesh. Is made uniform and the diameter is reduced. For this reason, the number of components to be housed in the main body case to form bubbles is reduced, and the size of the foam generator is reduced.
【００１０】請求項２記載の発明は、請求項１記載の発

器が小型化される。Therefore, it is possible to generate sufficiently fine bubbles without increasing the number of stages of the mesh used, for example, even when the number of stages is two or three, and the mesh required to generate sufficiently fine bubbles can be generated. The number of bodies is reduced and the foam generator is downsized.

Can be sucked into the main body case from an air suction port formed in the main body case. Therefore, when this foam generator is used, an air supply pipe for supplying air for generating foam is provided. No longer needed
Further, an air pump for sending air is not required, and cost can be reduced. In addition, the liquid discharged from the liquid discharge holes collides with the perforated plate, and the film of the colliding liquid covers the small holes of the perforated plate. In each small hole, the liquid that covers the small holes due to a pressure difference between before and after the perforated plate. Since the film of the foam expands and bubbles are generated, the rate of foam generation can be increased by providing a perforated plate. Can be achieved. As described above, by providing the perforated plate and the mesh body in the main body case, the number of components to be housed in the main body case to form bubbles can be reduced, and the size of the foam generator can be reduced.
