Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an improvement in a water soap supply device.

(Prior art) Conventionally, water soap is forcibly supplied via a supply pipe to a discharge nozzle installed at a location away from a tank containing water soap, and when the remaining amount of water soap in the tank is at a predetermined level. There are devices available that have the ability to display a warning light when the temperature drops to a certain level.

(Problem to be Solved by the Invention) However, in conventional water soap supply devices, the warning lamp display level in the tank is set at the time of shipment. The time from when it lights up until the remaining amount reaches 0 is short, so you may not be able to replenish the battery in time. In addition, if the warning lamp display level is set high, if the installation is installed in a place where it is not used frequently, reinforcement may be required even though there is sufficient water soap remaining, causing problems such as poor replenishment efficiency. .

It is equipped with a solenoid valve control means that operates the solenoid valve 10a when the target is reached. Furthermore, it is provided with display section control means that inputs a signal from the remaining amount detector 8 and causes the remaining amount display section 24 to turn on and blink, and a buzzer control means that makes the buzzer 25 sound.

As mentioned above, the pressurizing pump 21 is turned on when the supply port 11 is closed and turned off when it is opened, and the power is turned off when the supply port 11 is closed.
It operates when the internal pressure becomes lower than a predetermined pressure (for example, 0.4kgl/1ffl) to supply compressed air into the tank 1,
The operation is stopped when the pressure reaches a predetermined value (for example, I], 5kg1/cnf), and the remaining amount of water soap in the tank 1 reaches the lowest level of the remaining amount detector 8 (8a in the figure). It is controlled by the control unit 5 so that the power is turned off at certain times.

The solenoid valve 10a of the air vent 10 is a three-way solenoid valve that opens the air pipe 4 and closes the air vent 10 under normal conditions, and when the supply port 11 is opened as described above,
Or, it is activated when the remaining amount of water soap in the tank 1 reaches the lowest level of the remaining amount detector 8 (8a in the figure), and the air vent 1 is activated.
It is controlled by the control unit 5 to open the compressed air in the tank 1 and operate it again after a certain period of time (for example, 60 seconds) to close the air vent 10. Note that the air vent 10 can be provided separately and independently from the air piping 4, and in that case, the solenoid valve 10a is connected to the air vent 1.
Consists of an electromagnetic on-off valve that opens and closes 0.

The remaining amount display section 24 is formed by arranging light emitting diode elements 24a to 24e in a multi-stage manner corresponding to the remaining amount detector 8, and electrically connecting each of the elements 24a to 24e to the control section 5. Then, according to a command from the control unit 5, each of the elements 24a to 24e turns on when the remaining amount is detected by the corresponding contacts 8a to 8e, and the remaining amount of water soap in the tank 1 is displayed in stages. It has become. At the same time, the top element 2
4e, it blinks for a certain period of time (for example, 5 seconds) in response to a detection signal from the topmost contact 8e to warn of overflow when replenishing water soap, and then turns on.

The buzzer 25 sounds for a certain period of time (for example, 5 seconds) when the remaining amount of water soap reaches the top level (8 g in the figure) by the remaining amount detector 8, and the buzzer 25 sounds for a certain period of time (for example, 5 seconds) to stop the water soap from being refilled. It is controlled by the control unit 5 to warn of overflow.

On the other hand, the water soap supply pipe 3 taken from the tank 1
Each of the air pipes 4 is branched into a plurality of parts in the middle, and a discharge nozzle 6 is connected to each branched tip, and a check valve 6' is provided in each branched part.

The discharge nozzle 6 has a water soap inlet 6a and a compressed air inlet 6b at its base, and the water soap supply pipe 3 is connected to the former, and the air pipe 4 is connected to the latter.

Further, there is a mixing chamber 61 inside which communicates with the introduction ports 6a and 6b. A stirring chamber 62 communicating with the discharge port 6d is provided, and the mixing chamber 61 and the stirring chamber 62 are communicated via a small diameter passage 63.

The discharge nozzle 6 is provided with an on-off valve 6c, and the stirring chamber 62 is equipped with a plurality of nets 6e.

The above-mentioned on-off valve 6c may be an electric or electromagnetic type that opens for a certain period of time based on hand detection by a human sensor such as a photoelectric sensor or an electric signal based on the press operation of a touch switch, or it may be operated mechanically by pressing a push button. It may be a manual type that opens while the button is pressed or for a certain period of time, but the illustrated example shows a manual type opening/closing valve 6c that is operated by a push button 6C.

In the discharge nozzle 6, when the push button 6c is pressed, compressed air and water soap are mixed in the mixing chamber 61 and stirred by the net 6e.

Therefore, the water soap is discharged in a mousse state.

Dispensing water soap in the form of a mousse in this way not only prevents the water soap from splattering or running off when it hits your hands due to the force of the water soap being discharged due to the pressurized pressure, but also makes it possible to efficiently dispense small amounts of water soap. It is also effective in saving water and soap.

Note that a honeycomb structure is used instead of the net body 6e described above.

By installing a flow regulator having a star-shaped cross section, a spiral shape, a perforated plate shape, or the like, the same effect as when using the above-mentioned net body 6e can be obtained.

In addition, by making the size of the mesh of the mesh body 6e or the through holes defined inside the fluid regulator of various shapes arbitrary, the mixing state of air and water soap can be changed, and the mousse can be made smoother. The fineness of the water soap can be arbitrarily selected.

Furthermore, by appropriately changing the diameter of the discharge 06d, the force at which the water soap is discharged can be arbitrarily selected.

According to the above configuration, the remaining amount of water soap in the tank 1 is higher than the lowest level 8a of the remaining amount detector 8, and
is closed, the pressurizing pump 21 is operated so that the pressure inside the tank 1 is maintained within a certain range (for example, 0.3 to 0.5 kg1/ci), and each discharge nozzle 6 is filled with water soap and compressed air. supply air. At the same time, the remaining amount of water soap in the tank 1 is displayed in stages on the remaining amount display section 24.

Also, when the remaining amount of soap in the tank 1 reaches the lowest level 8a of the remaining amount detector 8, the pressure pump 21 is turned off and the air vent 10 is opened to bleed out the air in the tank 1. This prevents the residual amount of water soap from becoming lower than the take-out part of the supply pipe line 3, thereby preventing the risk of air entering the supply pipe line 3 and solidifying the water soap remaining in the pipe.

Furthermore, when the lid 13 is operated in the direction of opening the tank 1 to replenish the water soap, the pressure pump 21 is turned off and the air vent 10 is opened to evacuate the air inside the tank 1. The lid 13 flies off due to internal pressure a.
To eliminate the risk of danger and to safely open and close a supply port 11.

Furthermore, when the remaining amount of water soap in the tank l increases to the vicinity of the replenishment port 11 by replenishing the water soap, the buzzer 2
5 sounds and the topmost element 24e of the remaining amount display section 24 flashes to warn of overflow of water soap.

The above-mentioned control section 5 is configured to stop the operation of the pressurizing pump 21 in the cases of ■ to ■ described below, open the air vent 10 for a certain period of time by operating the solenoid valve t(la), and display the remaining amount on the remaining amount display section. It is optional to add an emergency stop means that causes all of the 24 elements 24a to 24[ to blink to notify the occurrence of an abnormality in the apparatus.

■ If the pressure inside the tank l is below (1.3 kgf/cff!) even after a certain period of time (for example, 5 minutes) has passed since the command to operate the pressure pump 21 is issued from the control unit 5, If the pressure inside the tank 1 is 0.3 kg1/cff1 or more even after a certain period of time (for example, 10 seconds) has passed since the command to operate the solenoid valve 10a of the outlet 10 is issued, the remaining amount detector 8 detects that the remaining amount is When the remaining amount of water soap is detected at a level other than the liquid level (effect of the invention) Since the water soap supply device of the present invention is configured as explained above, the remaining amount of water soap in the tank can be checked step by step. I can,
Therefore, water soap can be efficiently replenished according to the frequency of use of the place where the device is installed.
