2. Description of the Related Art Conventionally, a restaurant kitchen or the like is easily contaminated and a large floor surface has to be cleaned by a person using a deck brush or the like, which requires a lot of labor. However, the purpose is to reduce this labor. (Japanese Utility Model Laid-Open No. 4-44856 and Japanese Utility Model Laid-Open No. 5-13344) have been proposed. In addition, various devices for foaming a liquid for some purpose, such as a foaming device used for generating artificial foam or soap bubbles in a bathroom or a foaming cleaning device for a duct, are known. Further, in these conventional apparatuses, a technique is also disclosed in which a sponge contains a cleaning agent and air is blown into the sponge to form a foam.

However, the conventional apparatus cannot supply a sufficient amount of foam unless high-pressure air is sent.
A compressor or the like is required, and the whole apparatus becomes considerably large. For example, the apparatus cannot be used or is difficult to use for washing or cleaning a relatively small place such as a kitchen or a bathroom in a home. In addition, in the conventional apparatus, after foaming with a foaming device, the foam is sent to the discharge port using a pipe, a tube, or the like. And the bubble diameter becomes non-uniform. Furthermore, the conventional device is inferior in foam control,
It is difficult to make uniform foam, it is not easy to change the foam quality, the foaming rate is low, the amount of residual liquid is large, and most of the supplied liquid and air do not contribute to foaming and the efficiency is low. It is low. In addition, when a sponge is used, durability is poor, settling is fast, and cleaning when soiled is not easy.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a pressure of at most 0.4 kg / c at normal pressure.
It is an object of the present invention to provide a small and lightweight foaming machine and a small-sized foam washing machine using the same, which can perform foaming and foam regulation at a high foaming rate by air having a low pressure of about m ² .

[0008]

In the foaming device of the present invention, the diameter of the foam to be generated can be easily adjusted by changing the size of the mesh of the mesh.
The uniformity of the foam can be freely adjusted by changing the number of nets. By doing so, the thickness of the foam changes and the weight of the foam changes, so that the flowability, the defoaming time and the like can be adjusted at the same time. Further, by appropriately changing the liquid pressure, the liquid amount, the air pressure, and the air amount, and changing the diameters of the liquid supply pipe and the air supply pipe in combination therewith, the foaming ratio, foam quality, and the like can be adjusted over a wide range. Further, by providing the air blowing portion between the first and second meshes, the foaming ratio and the residual liquid amount can be reduced as compared with the case where only the foam stabilizing portion is provided. Furthermore, in the foaming device of the present invention, the fluidity of the foam is stabilized at the time of passing through the foam stabilizing section, and at the time of passing through the foaming and foam regulating section, the foam diameter is not uniform in the foam stabilizing section, or the foam is broken. The liquid remaining as it is is passed through a foam-forming and foam-regulating section to adjust the bubble diameter, and the liquid that has become liquid is foamed again and foam-regulated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the foaming apparatus of the present invention and a foaming method using the same will be described below with reference to the drawings. Although the shape of the foaming device main body 2 is not particularly limited, a cylindrical body having a circular cross section, a triangle, a quadrangle or the like is usually used. The material may be any material that does not deteriorate with a liquid agent such as a cleaning agent to be used, and polyolefins such as polyethylene and polypropylene, synthetic resins such as polyvinyl chloride and polycarbonate, and metals such as stainless steel can be used. Further, the foaming device main body 2 only needs to have such a strength that the shape can be maintained and the foaming device main body 2 is not easily broken by an external impact.

The material of the liquid supply pipe 3 and the air supply pipe 4 is not particularly limited either. The liquid supply pipe 3 and the air supply pipe 4 may be made of a material having high rigidity such as metal as long as they are not deteriorated by the liquid used. It may be a flexible tube.
Further, as the nets 51 to 56, those made of metal are usually used. The mesh is 40-100 mesh, especially 60 mesh
Those having a size of ~ 80 mesh can be used. When a mesh having a small mesh is used, a bubble having a small average diameter is generated, and when a mesh having a large mesh is used, a bubble having a large bubble diameter is obtained. The first and second reticulated bodies are indispensable, and more than one may be attached as needed.

The space between the first and second meshes serves as an air blowing section 6, and the space between the meshes has the function of stabilizing the generated foam. Has the effect of Therefore, when the number of sheets is increased, the foam becomes more stable, about 40% or more of the supplied air contributes to foam generation, and more than 30% of the supplied liquid, often about 60% or more, and further, substantially the entire amount thereof. Is foamed, and very efficient foaming becomes possible. However, it is meaningless to use too many reticulated bodies, and foaming with sufficiently high efficiency is usually possible when about 3 to 8 sheets are used. The space between the meshes may be adjusted according to the required bubble diameter, and the larger the required bubble diameter, the larger the space volume.

The dimensions of each part of the foaming device of the present invention are not particularly limited, but specific examples include a diameter of the foaming device body 2 of 13 to 16 mm, a length of 70 to 80 mm, and a liquid. The diameter of the supply pipe 3 is 4 to 5 mm, the opening diameter of the narrowed portion 31 at the tip thereof is 1 to 2 mm, the diameter of the air supply pipe 4 is 6 to 8 mm, and the interval between the nets 51 to 56 is about 5 to 10 mm. be able to.

A method for producing a foam using the foamer 1 of the present invention will be described below. Although not shown, the liquid supply pipe 3
Is connected to a liquid supply source in which the prepared cleaning agent and the like are stored, and the air supply pipe 4 is connected to an air supply source such as a compressor and a blower. The cleaning agent is not particularly limited, but in this foam example, a process cleaner having a yellow transparent appearance (Yushilo Chemical Co., grade name "810")
F ") diluted with water to about several tens to 100 times. Foaming is first performed from the air supply pipe 4 to 0.05 to 0.4.
Air is supplied at a pressure of about atmospheric pressure, and then supply of a cleaning agent diluted about 50 to 100 times with water from the liquid supply pipe 3 is started. In this case, the volume ratio between the air amount and the liquid amount is about 15 to 30: 1. In addition, the distal end of the liquid supply pipe 3 may be narrowed down to a small diameter, and the liquid may be ejected without applying a particularly strong pressure, and the throttle 31 may be provided so as to evenly spread over the entire surface of the second mesh body 52. preferable.

The detergent adhering to the mesh of the second mesh 52 as described above is foamed by the air blown from the direction of the first mesh 51. The generated foam is the second
Is stabilized in the space between the reticulated body 52 and the next reticulated body 53, and then foamed by the reticulated body 53 and foam-regulated at the same time. Thereafter, the foams are successively reticulated 54, 55 and 56.
While moving, the mesh is stabilized between the meshes, and foaming and foaming are performed by the meshes. By performing foaming and foam control over several stages as described above, it is possible to foam substantially 100% of the supplied cleaning liquid, and the supplied air can be changed depending on operating conditions. Utilization rate [1 divided by the amount of foaming (l / min) divided by the amount of supplied air (l / min)]
The value (%) multiplied by 00] may be about 40%, but in particular, in the foaming device of the present invention, the utilization rate is substantially 100%.
% And the air utilization is very good.

In the above operation procedure, the supply of air is first started, and then the liquid agent is supplied. By doing so, a decrease in the amount of foam due to an excessive amount of liquid at startup and restart is prevented. You. When the operation is stopped, the supply of the liquid is stopped first, and then the air is stopped, contrary to the operation start.
As a result, the liquid remaining in the foaming device without foaming can be minimized, and the foam can be easily defoamed at the time of restart, and the problem that the amount of foaming is reduced is prevented. The foaming was performed using the foaming device of the present invention as described above, and the results when good foaming was possible and the respective foaming conditions are shown in Tables 1 to 3. Table 1 shows the case where the mesh of the mesh is 60 mesh and the number of used is 3 sheets.
Indicates that the mesh of the mesh is 60 mesh and the number of used is 4
Table 3 shows that the mesh of the mesh is 80 mesh, and the number of used is 3 or 4.
This is the result in the case of one sheet.

It should be noted that the present invention is not limited to the specific embodiments described above, but can be variously modified within the scope of the present invention in accordance with the purpose and application. For example, in the above-described embodiment, an example in which the cleaning agent is used with a very small foaming device has been described. However, the size of the foaming device, the foam supply capacity, and the like can be arbitrarily changed, and the foaming device of the present invention is used. For example, a single bubbler can be used as the small bubble cleaning machine of the present invention, or a plurality of such devices can be incorporated into a cleaning machine generally used for cleaning floors of public facilities and large buildings. .

In the case of the above-mentioned small bubble washer, ancillary equipment such as a blower, a liquid storage tank, and a liquid supply pump are integrally compacted, liquid and air are transferred by a tube, and an appropriately shaped nozzle is provided at the end of the tube. The attached foamer can be connected to form a washing machine. As an example of the specification, power consumption is 3.9 to 4.1 A and air volume is 15 to 20 l.
/ Min, and a liquid discharge amount of about 0.05 to 0.20 l / min. Also, in the case of a washing machine using a plurality of the above-described foamers, instead of transporting foam to a discharge port by a pipe or the like as in the related art, the foam is transported because the foamer itself exists near the discharge port. Are liquid and air,
It is much easier than transferring foam.

Further, the medicine currently used by spraying in the form of a mist can be foamed and sprayed, so that the present invention can be applied to spraying disinfectants in fields, greenhouses, golf courses and the like. In the conventional method of spraying in the form of a mist, there was a major environmental problem such as scattering of the medicine to unnecessary places or inhalation of the medicine by the operator. The effect of the foamer of the present invention is remarkable particularly in use in a closed place, for example, in the above-mentioned greenhouse, in a tank, in a duct, or the like.

In addition to the above, even in the field where a coating material such as a film coating, a rust prevention coating, a fluorine coating or the like is conventionally sprayed in the form of a liquid or a mist, the foaming operation of the present invention is carried out in the form of a foam. In addition, it can be applied to the coating of a dustproof agent, which has been conventionally considered to be non-foaming, and can be applied to various fields which originally had the concept of painting and coating. Furthermore, in the case of the conventional liquid or mist form, when sprayed on a vertical surface or the like, it becomes streaked and drips downward (so-called streak unevenness), and application unevenness easily occurs. It is preferable that a uniform film is formed on the application surface.

[0023]

The foaming device of the first invention does not require a large-scale device such as a high-pressure compressor and can be foamed by compressed air such as that of a blower. The device can be made extremely small and lightweight, and the peripheral equipment does not become large-scale. In addition, almost all of the supplied liquid and air can be used for foaming, so that a very efficient product can be manufactured. It is a foamer. Further, the diameter, hardness and the like of the foam to be generated can be arbitrarily and easily changed. Further, by adopting the liquid supply pipe structure as in the second invention, the efficiency of foaming becomes higher. Further, by setting the mesh of the net-like body in the specific range of the third invention, foaming and foam-regulating become easier. Furthermore, the fourth
According to the invention, it is possible to obtain a cleaning machine having excellent effects particularly suitable for cleaning a narrow place having the effects of the first to third inventions.
