In particular, as will be described in an embodiment described later, a liquid supply pipe configured to serve as both the surfactant supply means and the water supply means, and a gas supply pipe that constitutes the gas supply passage are supplied. It is preferable that the upper part is provided so as to surround the supply target.

Here, the amount of diluted water of the surfactant aqueous solution is usually required to be 1/100 to 1/200 depending on the degree of dirt such as oil. Moreover, the amount of dilution water of this surfactant aqueous solution is proportional to the foaming area. On the other hand, at the time of washing with water, a predetermined amount of water is required. In general, the larger the aperture, the better the washing result.
From the above, for example, as shown in FIGS. 26 and 27, the water supply means is a first communication path 101 for connecting the foaming means and a water supply source, and for water washing provided in the middle of the first communication path. An on-off valve 104a, and the surfactant supply means connects the upstream side and the downstream side of the flushing on-off valve of the first communication path, and a dilution provided on the bypass path The on-off valve 104b and the water control device 99, the second communication channel 102 that communicates the downstream side of the water control device of the bypass channel and the surfactant supply source, and is provided in the middle of the second communication channel.

The structure and arrangement of the “water supply source” are not particularly limited. Examples of the water supply source include tap water faucets and water storage tanks.
There are no particular restrictions on the type, installation form, etc. of the “first communication path”, “second communication path”, and “bypass path”. Examples of the first communication path, the second communication path, and the bypass path include a communication pipe (including a tube), a communication path, and the like.
There is no particular limitation on the structure, arrangement, etc. of the above-mentioned “water washing on-off valve” and “dilution on-off valve”. Examples of these on-off valves include electromagnetic valves.
The structure, arrangement form, etc. of the “water control device” are not particularly limited. Examples of the water control device include a flow rate adjustment valve.

The structure and arrangement of the “control means” are not particularly limited. This control means is usually configured with a CPU, a ROM, a RAM, and the like. For example, when supplying water to the supply target, this control means can turn on the flushing on-off valve 104a and can turn off the dilution on-off valve 104b and the delivery means 106.
In addition, the said structure shall be applied similarly also with the following forms.

However, in the above-described embodiment, the water control device is replaced or the discharge size of the delivery means is changed according to the number and size of the foaming means (for example, a foaming device) to match the foaming area. It was necessary to perform on-site adjustment. Therefore, the replacement work of the water control device, the delivery means, and the like is complicated, and the installation location of the parts is limited, so that the entire system has a relatively expensive and complicated structure.
Therefore, as a form for solving the above problem, for example, as shown in FIGS. 28 and 29, the water supply means includes a first communication path 111 that connects the foaming means and a water supply source, and the first communication path. An on-off valve 114 provided in the middle of the first connection path, and the surfactant supply means connects the downstream side of the on-off valve of the first connection path with the surfactant supply source, and a second connection path 112 And a delivery means 116 for delivering the surfactant aqueous solution from the surfactant supply source to the second communication path provided in the middle of the second communication path, and the foamed surfactant aqueous solution. When supplying to the supply target, it is possible to further include control means 119 for repeatedly ON / OFF controlling the on-off valve and repeatedly ON / OFF controlling the delivery means for a predetermined time. Thereby, the above-mentioned diluting on-off valve and water control device can be omitted, and the entire system can be made inexpensive and simple. Further, by changing the ratio t1 / t2 between the ON time t1 and the OFF time t2 of the on-off valve and the ratio t3 / t4 between the ON time t3 and the OFF time t4 of the delivery means, dilution of the surfactant aqueous solution The amount of water, dilution ratio, etc. can be easily adjusted.

For example, when supplying water to the supply target, the control means can perform ON control or repeated ON / OFF control of the on-off valve and OFF control of the delivery means within a predetermined time. The control means may be, for example, (1) a ratio changing means for changing a ratio between the ON time and the OFF time of the opening / closing valve and a ratio between the ON time and the OFF time of the sending means; ON / OFF time of the valve and time changing means for changing the ON time and OFF time of the sending means, (3) ON / OFF repetition number of the opening / closing valve, and ON / OFF repetition number of the sending means 1 type or 2 types or more of repeating number changing means for changing Thereby, the amount of dilution water, dilution ratio, etc. of surfactant aqueous solution can be adjusted more easily.

Moreover, it is preferable that this foaming unit main body consists of the material containing the mold prevention agent from a viewpoint of mold prevention.

In this case, the passage block is provided with various passages, which will be described later, and the foam block is provided with various passages, a foam portion, a communication path connecting the passage and the foam portion, and an adjacent foam block. A partition portion for partitioning the foaming liquid supply passage may be provided.

The “foaming part” is not particularly limited in structure, shape, size, and the like as long as the surfactant aqueous solution can be foamed. This foaming part is normally comprised by providing a foam in a foaming channel. Examples of the foam include a net (such as a wire mesh), a bundle (such as a scourer), a cotton (such as steel wool and glass wool), and a porous (such as a sponge and a porous filter). Further, for example, a plurality of the net-like bodies can be arranged in parallel at predetermined intervals along the axial direction inside the foam passage. In addition, as this mesh body, what was demonstrated in the above-mentioned Embodiment 1 is applicable, for example.
Moreover, this foaming part can have a throttle part, for example in the connection part with the gas supply path and surfactant supply path which are mentioned later. Thereby, surfactant aqueous solution, gas, water, and a foaming liquid are uniformly distributed to the foaming liquid supply channel of each foaming unit, and it can respond to a wider range of supply object. This throttle part can be, for example, a mixing passage part through which a gas and a surfactant aqueous solution are mixed.

Furthermore, in the above-described forms (1) to (3), for example, a surfactant aqueous solution as a stock solution and dilution water can be simultaneously supplied to the surfactant supply passage.

Here, from the viewpoint of dealing with a relatively wide range of supply targets, in the above-described form (1), the foaming liquid supply passages are defined in the adjacent foaming units in the unit connected body, and the gas supply to each other is made. The passage, the surfactant supply passage, and the water supply passage are preferably communicated with each other.

Here, the dilution amount of the surfactant aqueous solution usually requires 1/100 to 1/200 depending on the degree of dirt such as oil. Moreover, the amount of dilution water of this surfactant aqueous solution is proportional to the foaming area. On the other hand, at the time of washing with water, a predetermined amount of water is required. In general, the larger the aperture, the better the washing result.

The structure, arrangement form, etc. of the “water control device” are not particularly limited. Examples of the water control device include a flow rate adjustment valve.
The structure and arrangement of the “control means” are not particularly limited. This control means is usually configured with a CPU, a ROM, a RAM, and the like. For example, when supplying water to a supply target, the control means can control the ON / OFF of the flushing on / off valve and can control the dilution on / off valve and the delivery means to OFF.
In addition, the said structure shall be applied similarly also with the following forms.

However, in the above-mentioned form, it is necessary to perform on-site adjustment according to the foaming area by replacing the water control device or changing the discharge size of the delivery means according to the number and size of the foaming parts. was there. Therefore, the replacement work of the water control device, the delivery means, and the like is complicated, and the installation location of the parts is limited, so that the entire system has a relatively expensive and complicated structure.

And a control means 119 for controlling the sending means repeatedly ON / OFF. Thereby, the above-mentioned diluting on-off valve and water control device can be omitted, and the entire system can be made inexpensive and simple. Further, by changing the ratio t1 / t2 between the ON time t1 and the OFF time t2 of the on-off valve and the ratio t3 / t4 between the ON time t3 and the OFF time t4 of the delivery means, dilution of the surfactant aqueous solution The amount of water, dilution ratio, etc. can be easily adjusted.

The structure and arrangement of the “control means” are not particularly limited. This control means is usually configured with a CPU, a ROM, a RAM, and the like. For example, when supplying water to the supply target, the control means can perform ON control or repeated ON / OFF control of the on-off valve and OFF control of the delivery means within a predetermined time. The control means may be, for example, (1) a ratio changing means for changing a ratio between the ON time and the OFF time of the opening / closing valve and a ratio between the ON time and the OFF time of the sending means; ON / OFF time of the valve and interval changing means for changing the ON time and OFF time of the sending means, (3) ON / OFF repetition number of the opening / closing valve, and ON / OFF repetition number of the sending means 1 type or 2 types or more of repeating number changing means for changing Thereby, the amount of dilution water, dilution ratio, etc. of surfactant aqueous solution can be adjusted more easily.

In the case of the above configuration, for example, as shown in FIG. 30, in the middle of the first communication path 111, a storage container 120 for storing the surfactant aqueous solution downstream of the communication part with the second communication path 112.

There is no particular limitation on the structure and arrangement of the delivery means. Examples of the delivery means include a pump and a blower.
For example, when supplying water to the supply target, the control means performs ON control or repeated ON / OFF control of the on-off valve and OFF control of the delivery means during a predetermined time, and further, The gas delivery means for supplying gas to the foaming part can be controlled ON or repeatedly ON / OFF. Thereby, water is more evenly distributed to the plurality of foamed portions, and the power of washing can be increased by increasing the momentum of the water. Examples of the gas delivery means include a pump and a blower.

One water supply pipe 45 may be provided in the vicinity of 6d, and water may be sprayed from the water supply pipe 45 to the floor surface without passing through the divided pipes 6a to 6d.

  Moreover, in the said Example 1, although each foamer 2a-2d was attached to the upper end part of each piping 29 for liquid supply, it is not limited to this, For example, as shown with a virtual line in FIG. The foamers 2 a to 2 d may be provided at the lower end of each liquid supply pipe 29.

  Then, after a predetermined time has elapsed, water is supplied to the connecting unit 51 from one end side thereof, and the water is supplied to each foaming unit U substantially evenly. Then, water is sprayed and sprayed from the many supply holes 65 onto the floor surface F through the water supply path 63 c of the passage block 53.

As shown in FIG. 18, adjacent foaming units U are connected to the corner portions via a substantially L-shaped connection block 66 in which communication passages (not shown) are appropriately formed. From the viewpoint of fluidity of fluid, the connecting block 66 is preferably curved.

(2) Operation of Floor Surface Cleaning System Next, the operation of the floor surface cleaning system 50 ′ configured as described above will be described. First, at the time of cleaning, as shown in FIG. 18, air and cleaning liquid are supplied from one end side to the unit connecting body 51A, and these air and cleaning liquid are supplied to each foaming unit U ′ substantially evenly. Then, in the foam block 52A of each foam unit U ′, the cleaning liquid is foamed while being mixed with air. Then, the foamed cleaning liquid is sprayed and sprayed from the large number of supply holes 64 to the floor surface F through the foaming liquid supply path 63d of the passage block 53A, and left in the sprayed state for a while.

  Then, after a predetermined time has elapsed, water is supplied to the connecting unit 51A from one end side thereof, and the water is supplied to each foaming unit U 'substantially evenly. Then, water is sprayed and sprayed from the large number of supply holes 65 onto the floor surface F through the foaming liquid supply path 63d of the passage block 53A.

Here, in the third embodiment, as shown in FIG. 24, the cleaning liquid supply path 63b is used in combination as a water supply path at the time of water washing, but the discharged water is the throttle part (the communication path 57d and the mixing path). 57e), most of the water reaches the foaming unit U ′ far away from the foaming unit U ′ close to the main body side (water supply source etc.) and supplies the foaming liquid to each foaming unit U ′. Water is uniformly drained from the path 63d.
Further, as shown in FIG. 25, when water is supplied to the cleaning liquid supply path 63b and air is supplied to the air supply path 63a at the same time, high pressure is applied to the air supply path 63a. Therefore, the water does not flow back to the air supply path 63a, the water can easily enter the foaming liquid supply path 63d, and the discharge of water comes out vigorously.

(Other examples)
Next, the forms (1) to (4) shown below will be described as supply forms of the cleaning agent and water in the foaming systems of Examples 1 to 3 described above. In addition, the same code | symbol is attached | subjected to the same component as the said Examples 1-3, and detailed description is abbreviate | omitted.

In the said form (1), as shown in FIG. 26, the foaming part (or foamer) and the water supply source (for example, tap water etc.) are connected by the 1st communication path 101. As shown in FIG. In the middle of the first communication path 101, a washing electromagnetic valve 104a is provided. Further, the upstream side and the downstream side of the electromagnetic valve 104 a for washing in the first communication path 101 are connected by a bypass path 105. In the middle of the bypass passage 105, a dilution electromagnetic valve 104b and a water control device 99 are provided. Further, the second communication path 102 communicates the downstream side of the water control device 99 in the bypass path 105 and the tank 10 storing the cleaning liquid. A T-shaped joint pipe 108 is provided at a connecting portion between the bypass path 105 and the second connecting path 102. In the middle of the second communication path 102, a liquid pump 106 for sending the cleaning liquid from the tank 10 is provided. Further, the foaming part (or the foamer) and the air pump 107 are communicated with each other through the third communication path 103. Further, a control circuit 109 for driving and controlling the washing electromagnetic valve 104a, the dilution electromagnetic valve 104b, the liquid pump 106, and the air pump 107 is provided.
In addition, as said "foaming part", the washing | cleaning liquid inflow path 55b of the foaming blocks 52 and 52A in Example 2, 3 can be illustrated, for example. Moreover, as said "foamer", the foamer 2 in Example 1 can be illustrated, for example.

  As shown in FIG. 27, when supplying the cleaning liquid to the supply target, the washing electromagnetic valve 104a is closed (OFF control) by the control circuit 109, and the dilution electromagnetic valve 104b is always opened for a predetermined time ( Further, the liquid pump 106 is always driven (ON control) for a predetermined time. Further, the air pump 107 is constantly driven (ON control) for a predetermined time by the control circuit 109. Then, the diluting water whose flow rate is reduced by the water control device 99 is supplied to the bypass passage 105. Further, the cleaning liquid is sent to the second communication path 102 by the liquid pump 106, and the cleaning liquid is mixed with the dilution water and diluted by the T-shaped joint pipe 108, and the diluted cleaning liquid is the foaming part (or foamer). To be supplied. In addition, air is supplied to the foaming section (or foamer) by the action of the air pump 107. As a result, in the foaming part (or foamer), the diluted cleaning liquid is mixed with air and foamed, and then the foamed cleaning liquid is supplied to the supply target.

  On the other hand, when supplying water to the supply target, the electromagnetic solenoid 104b for dilution is closed (OFF control) by the control circuit 109, and the liquid pump 106 and the air pump 107 are stopped (OFF control). The electromagnetic valve 104a is always opened (ON control) for a predetermined time. Then, water will be supplied to a foaming part (or foamer) via the 1st communication path 101, and will be supplied to a supply object after that.

  Here, in the above-described form (1), the water control device 99 is replaced or the discharge size of the liquid pump 106 is changed according to the number and size of the foaming portions, so as to match the foaming area. It was necessary to carry out field adjustments. Therefore, the replacement work of the water control device 99, the liquid pump 106, and the like is complicated, and the installation location of the parts is limited, so that the entire system becomes a relatively expensive and complicated structure.

Therefore, the mode (2) for solving the above problem will be described.
In the said form (2), as shown in FIG. 28, the foaming part (or foamer) and the water supply source (for example, tap water etc.) are connected by the 1st communication path 111. As shown in FIG. An electromagnetic valve 114 is provided in the middle of the first communication path 111. Further, the downstream side of the electromagnetic valve 114 of the first communication path 111 and the tank 10 storing the cleaning liquid are connected by the second communication path 112. A T-joint pipe 118 is provided at a connecting portion between the first connecting path 111 and the second connecting path 112. A liquid pump 116 for sending the cleaning liquid from the tank 10 is provided in the middle of the second communication path 112. Further, the foaming part (or foamer) and the air pump 117 are connected by a third communication path 113. Furthermore, a control circuit 119 for driving and controlling the electromagnetic valve 114, the liquid pump 116, and the air pump 117 is provided.

  The control circuit 119 can repeat ON / OFF control of the solenoid valve 114 and the liquid pump 116 by a pulse signal. Further, the control circuit 119 has a ratio between the ON time and the OFF time (t1 / t2, t3 / t4; see FIG. 29), ON time (t1, t3), and OFF time (t2) in the repeated ON / OFF control. , T4), and the number of repetitions (in FIG. 29, 7 times the electromagnetic valve, 5 times the liquid pump) and the like, and each value stored in the storage unit 119a is appropriately input means (for example, adjustment) A change unit 119b that changes via a knob or the like.

  As shown in FIG. 29, when supplying the cleaning liquid to the supply target, the control circuit 119 repeatedly opens and closes the electromagnetic valve 114 (ON / OFF control), and the liquid pump 116 is repeatedly driven and stopped ( ON / OFF control). Further, the air pump 117 is constantly driven (ON control) for a predetermined time by the control circuit 119. Then, a predetermined amount of dilution water is supplied to the first communication path 111. In addition, a predetermined amount of cleaning liquid is sent to the second communication path 112 by the action of the liquid pump 116, and the cleaning liquid is mixed and diluted with dilution water in the T-shaped joint pipe 118, and the diluted cleaning liquid Is supplied to the foaming section (or foamer). Air is supplied to the foaming part (or foamer) by the action of the air pump 117. As a result, in the foaming part (or foamer), the diluted cleaning liquid is mixed with air and foamed, and then the foamed cleaning liquid is supplied to the supply target.

On the other hand, when supplying water to the supply target, the liquid pump 116 and the air pump 117 are stopped (OFF control) by the control circuit 119, and the electromagnetic valve 114 is always opened (ON control) for a predetermined time. Then, water will be supplied to a foaming part (or foamer) via the 1st communication path 111, and will be supplied to a supply object after that.
In the above embodiment, when supplying water to the supply target, the electromagnetic valve 114 is always opened. However, the present invention is not limited to this. For example, the number, size, etc., of the foaming parts (or foamers) Accordingly, the electromagnetic valve 114 may be repeatedly opened and closed (ON / OFF control).

  From the above, according to the above (2) form, the electromagnetic solenoid 104b for dilution and the water control device 99 can be omitted as compared with the above (1) form, and the system as a whole has a low cost and simple structure. Can do. Further, the ratio of ON / OFF of the electromagnetic valve 114 and the liquid pump 116, each time interval, depending on the foaming area to be supplied (that is, the number and size of foaming parts and foamers), the degree of dirt such as oil, etc. The number of repetitions and the like can be set and changed as appropriate, and the amount of dilution water and the dilution ratio of the aqueous surfactant solution can be easily changed and handled. Furthermore, even if the power supply frequency is different in Kansai, Kanto, etc., it is not necessary to adjust the liquid amount (discharge amount) by the liquid pump 116 (the number of rotations of the motor).

Here, it is assumed that the pipe diameter of the first communication path 111 is ½ mm, a water amount of about 30 L / min is obtained, and the discharge capacity of the liquid pump 116 is 100 cc / min. And the case where the dilution ratio of surfactant is set to 1/100 and the amount of dilution water is set to 5 L / min is demonstrated.
In order to obtain the dilution water amount 5 L / min, the ratio of the ON time t1 and the OFF time t2 of the solenoid valve 114 may be 5 L / 30 L, that is, the OFF time 6 with respect to the ON time 1.
In order to obtain a dilution ratio of 1/100, it is necessary to send out 1/100 of a dilution water amount of 5 L / min, that is, a cleaning liquid of 50 cc / min. Therefore, if the ratio of the pump ON time t3 to the OFF time t3 is halved, a pump capacity of 50 cc / min can be obtained.

Note that when the ON / OFF interval of the electromagnetic valve 114 and the liquid pump 116 is extended, even if the amount of dilution water and the dilution ratio of the surfactant aqueous solution are the same, unevenness may occur in them.
Therefore, if the ON / OFF ratio is kept constant and the ON / OFF repetition number is increased, the result is almost the same as that operated continuously, and there is no unevenness in the amount of dilution water and the dilution ratio.
However, extremely increasing the number of ON / OFF repetitions particularly affects the life of the electromagnetic valve 114, and therefore, an appropriate number of ON / OFF repetitions is required.

Here, a mode (3) that can reduce unevenness in the amount of dilution water and the dilution ratio of the surfactant aqueous solution without extremely increasing the number of ON / OFF repetitions will be described.
The said form (3) is a structure substantially the same as the said form (2), attaches | subjects the same code | symbol to the same structural part, and abbreviate | omits detailed description. And the difference between the said form (3) and the said form (2) is, as shown in FIG. 30, in the middle of the 1st connection path 111, the washing | cleaning liquid in the downstream of the connection part with the 2nd connection path 112. Is that a storage container 120 for storing the water is provided. As a result, the cleaning liquid is mixed with the dilution water, temporarily stored in the storage container 120, and after the unevenness of the amount of dilution water and the dilution ratio is reduced, the cleaning liquid is supplied to the foaming section (or the foaming device). . The storage container 120 can be constituted by, for example, a pipe having a pipe diameter larger than the pipe constituting the first communication path 111 and having a predetermined length.
In addition, as shown with the virtual line in FIG. 30, the storage container 121 which stores air can also be provided in the middle of the 3rd connection path 113. FIG.

  Next, when dividing a plurality of foaming parts (or foamers) into an A circuit and a B circuit, for example, as shown in FIG. 17, a plurality of foaming parts (or foamers) arranged on the left side of the supply target ) Is an A circuit, and the above-described form (4), which is preferable when a plurality of foaming portions (or foamers) disposed on the right side of the supply target is a B circuit, will be described.

  The configuration (4) has substantially the same configuration as the configuration (2), and the same components are denoted by the same reference numerals and detailed description thereof is omitted. And the difference between the said form (4) and the said form (2) is, as shown in FIG. 31, the downstream of the 1st connection path 111 is made into the bifurcated branch path 111a, 111b, and each branch path 111a , 111b are provided with respective solenoid valves 122, 123, and the downstream side of the third communication path 113 is formed into a bifurcated branch path 113a, 113b, and the respective solenoid valves 124, 125 are provided in the respective branch paths 113a, 113b. It is in the point provided.
