In the present invention, water (hot water) from a water supply source such as a boiler and carbon dioxide gas from a carbon dioxide supply source including a carbon dioxide cylinder are mixed and stirred by a cascade pump, and the number of revolutions of the cascade pump is controlled to be arbitrary.

JP 2001-293342 A JP 2013-86078 A

  The carbonated water producing apparatus proposed in Patent Document 1 does not include means for easily changing the target carbonated water concentration once it is set. In the carbonated water discharge device proposed in Patent Document 2, the carbonated water concentration can be changed. However, since the configuration uses a cascade pump, for example, the amount of water can be adjusted by a water stopcock provided in the hair washing bowl. There is a demand from users to obtain something more convenient to use. In addition, if the carbon dioxide in the cylinder becomes small, the pressure of the supplied carbon dioxide gas decreases and a fixed concentration of carbonated water cannot be obtained. There was room for improvement from the viewpoint of effective use of carbon dioxide gas.

  The present invention has been proposed in view of the above circumstances, and it is possible to adjust the amount of water by a water stop cock provided in the hair washing bowl, and to use up the carbon dioxide gas in the cylinder, so that the carbonated water discharge is extremely easy to use. An object is to provide an apparatus.

  In the carbonated water discharge device according to the present invention, the pressure of the carbon dioxide gas supplied from the carbon dioxide gas supply source is measured by a pressure sensor, and the control board determines the operation amount of the valve based on the pressure measurement value, and the valve is operated. It is characterized in that the amount of carbon dioxide mixed with the raw water is controlled.

  Further, the flow rate of the raw water adjusted through the stop cock is measured by the flow sensor, and the control board determines the operation amount of the valve based on the flow rate measurement value, moves the valve, and is thereby mixed with the raw water. The amount of carbon dioxide gas is controlled.

  The control board is configured to determine one valve operation amount based on the pressure measurement value measured by the pressure sensor and the flow measurement value measured by the flow sensor, and to move the valve based on the operation amount. Preferably there is.

  The carbon dioxide gas is more preferably configured to be injected and mixed into the raw water stream through a small-diameter hole.

  In the carbonated water discharge device according to the present invention, the control base determines the operation amount of the valve based on the measured pressure value of the carbon dioxide gas measured by the pressure sensor, and moves the valve, whereby the amount of carbon dioxide gas mixed into the raw water Is configured to be controlled. Therefore, even if the carbon dioxide gas in the cylinder is reduced and the pressure of the supplied gas is reduced, the amount of carbon dioxide gas can be mixed with the raw water while controlling the amount of carbon dioxide with a valve based on the reduced gas pressure. Concentrated carbonated water can be obtained.

  Furthermore, the flow rate of the raw water adjusted through the stop cock is measured by the flow sensor, and the control board determines the operating amount of the valve based on this flow rate measurement value, and moves the valve, thereby the carbon dioxide gas mixed into the raw water. A configuration is also provided in which the amount is controlled. Therefore, it is possible to provide a carbonated water discharge device that can adjust the amount of water with a stop cock familiar to the user and that can obtain carbonated water with a constant concentration and is extremely easy to use. Note that the water pressure of the raw water supplied to the carbonated water discharge device may be an appropriate pressure, and the type of shower head to be attached to the discharge port of the carbonated water discharge device may be appropriate, and is particularly limited. It will not be done.

  The present invention has a configuration in which the control base determines one valve operation amount based on the pressure measurement value measured by the pressure sensor and the flow measurement value measured by the flow sensor, and moves the valve based on the operation amount. It is preferable. The amount of valve operation is inversely proportional to the gas pressure and proportional to the flow rate, so the control to obtain a constant concentration of carbonated water is somewhat complicated. Since only one valve operation amount is determined and the valve is moved, the carbonated water having the target concentration can be obtained with certainty. Then, it becomes possible to provide a carbonated water discharge device that can flexibly cope with changes in the flow rate of raw water supplied from the stop cock and pressure changes in the gas supplied from the cylinder.

  In addition, if carbon dioxide gas is injected and mixed into the raw water stream through a small-diameter hole, the carbon dioxide gas can be vigorously mixed into the raw water stream, so that the carbon dioxide gas is more efficiently mixed with the raw water. It can be dissolved in water and can effectively give the action of carbonated water.

  Note that since the present invention does not require a cascade pump, the configuration is simple, the size can be reduced, power consumption can be suppressed, and the cost can be reduced.

It is a block diagram explaining the schematic structure of the carbonated water discharge apparatus which concerns on this invention. It is explanatory drawing which showed typically a mode that carbon dioxide gas was stirred and mixed with raw | natural water through the orifice in the carbonated water discharge apparatus which concerns on this invention.

  Hereinafter, an embodiment of a carbonated water discharge device according to the present invention will be described with reference to the drawings. This embodiment is merely an example embodying the configuration of the present invention, and various design changes can be made to the present invention without departing from the matters described in the claims.

  As schematically shown in FIG. 1, a carbonated water discharge device X according to the present invention includes a gas path 10 of the apparatus body, a pressure sensor 1 that measures the pressure of carbon dioxide gas G supplied to the gas path 10, A water channel 20 of the apparatus main body and a flow rate sensor 2 for measuring the flow rate of the raw water L supplied to the water channel 20 from the stop cock F are provided. Furthermore, for example, a proportional control valve 3 is provided as a valve for determining the amount of carbon dioxide G to be mixed into the raw water L by an opening / closing operation. The pressure measurement value measured by the pressure sensor 1 and the flow measurement value measured by the flow sensor 2 are input, the operation amount of the proportional control valve 3 is determined based on these numerical values, and the proportional control valve 3 is output. A moving control base 4 is also provided. As shown in FIG. 1, in the carbonated water discharge device X, carbon dioxide gas G is, for example, an orifice 5 (see also FIG. 2) as a small-diameter hole in a mixing unit 30 that is a connection part between a gas channel 10 and a water channel 20. To the raw water L. As will be described later, the orifice 5 is disposed in the mixing unit 30 so that the carbon dioxide G is sufficiently stirred when the carbon dioxide G is ejected into the water stream of the raw water L, so that the carbon dioxide G is efficiently supplied to the raw water L. Can be melted.

The pressure sensor 1 is a carbon dioxide gas supplied to the gas passage 10 from a carbon dioxide gas supply source (for example, a carbon dioxide (CO ₂ ) cylinder) through a regulator for limiting the supply so as not to be supplied at a certain pressure or higher for maintenance of the apparatus. Measure the pressure of G itself. The pressure measurement value measured by the pressure sensor 1 is output to the control board 4. In addition, a well-known thing can be employ | adopted for the pressure sensor 1. FIG. The regulator may be installed either inside or outside the device.

  The flow rate sensor 2 is a flow rate of the raw water L supplied from the water (hot water) supply source (not shown) such as a boiler that discharges water and hot water to the water channel 20 after the flow rate is adjusted by the stop cock F outside the apparatus. Measure. The flow sensor 2 measures the flow rate per hour of the raw water L itself flowing through the water channel 20. The flow rate measurement value measured by the flow sensor 2 is output to the control board 4. A well-known sensor can also be used for the flow sensor 2.

  The proportional control valve 3 is a valve that can obtain a valve opening degree proportional to the intensity of the input signal (output signal from the control board 4), and quantitatively controls the amount of carbon dioxide G to be mixed with the raw water L. It can be carried out. In the present invention, in addition to the proportional control valve 3 described above, an electromagnetic valve may be employed as the valve. In this case, for example, it is possible to quantitatively control the amount of carbon dioxide gas by combining a plurality of solenoid valves.

  Based on the pressure measurement value measured by the pressure sensor 1, the control board 4 determines the amount of operation of the proportional control valve 3 based on the difference from the preset pressure value, moves it, and is mixed with the raw water L. The amount of carbon dioxide G is controlled. That is, when the carbon dioxide gas G in the cylinder becomes a little remaining and the gas pressure of the carbon dioxide gas G supplied to the gas passage 20 decreases, the difference from the preset pressure is increased due to this decrease. Then, the operation amount of the proportional control valve 3 is determined, for example, the proportional control valve 3 is moved so that the opening degree is relatively large, and the carbonated water to be produced has a concentration as set in advance. The amount of carbon dioxide G in the gas passage 10 after passing through the proportional control valve 3 is controlled. Thereby, the carbonated water discharge device X always produces carbonated water having a predetermined concentration set in advance.

  Further, the control board 4 determines and moves the operation amount of the proportional control valve 3 from the difference from the preset flow rate value based on the flow rate measurement value measured by the flow sensor 2. To control the amount of carbon dioxide G to be mixed. That is, for example, a flow rate when the stop cock F is fully opened is set in advance, and the set flow rate and a flow rate that is a value of the flow rate adjusted by the stop cock F actually measured by the flow sensor 2. From the difference from the measured value, the operation amount of the proportional control valve 3 is determined correspondingly. For example, the proportional control valve 3 is moved so that the opening degree is relatively small, and the carbonated water to be manufactured is preset. The amount of carbon dioxide G in the gas passage 10 after passing through the proportional control valve 3 is controlled so that the concentration is as it is. Also by this, carbonated water discharge apparatus X always produces carbonated water having a predetermined concentration set in advance.

  In particular, in the present invention, the control board 4 calculates and calculates the difference between the pressure and the flow rate based on the two variables of the pressure measurement value measured by the pressure sensor 1 and the flow rate measurement value measured by the flow sensor 2. As a solution, one operation amount of the proportional control valve 3 is determined. And it is the structure which moves the proportional control valve 3 based on this determined one operation amount. That is, the opening degree of the proportional control valve 3 is flexibly controlled with respect to the change in the gas pressure of the carbon dioxide G supplied to the gas passage 10 and the change in the flow rate of the raw water L in the water passage 20 due to the stop cock F. Carbonated water can be produced at a concentration as set in advance. As a result, carbonated water having a predetermined concentration set in advance is reliably produced in the carbonated water discharge device X. The carbon dioxide gas G can be used without waste until the cylinder is exhausted. The practitioner can provide a service using carbonated water to the practitioner while flexibly adjusting the flow rate by adjusting the stop cock F.

  In the present invention, as another embodiment, a proportional control valve is prepared for each of pressure and flow, and the control base is a proportional control valve for pressure based on the pressure measurement value measured by the pressure sensor. The control base determines the amount of operation of the proportional control valve for flow rate based on the flow rate measurement value measured by the flow sensor and moves it to control the amount of carbon dioxide gas As a result of these controls, a configuration may be adopted in which carbonated water having a predetermined concentration is produced by introducing the carbon dioxide gas G to a predetermined amount in the mixing unit. Even with such a carbonated water discharge device, carbonated water having a predetermined concentration can be produced.

  Here, as shown in FIG. 2, in the carbonated water discharge device X in the present embodiment, the connection between the gas passage 10 and the water passage 20, that is, the carbon dioxide G whose amount is controlled by the proportional control valve 3 is the raw water. In the mixing part 30 mixed with L, it is preferable that a plurality of orifices 5 which are small-diameter holes are arranged. Since the plurality of orifices 5 are arranged, the carbon dioxide gas G is vigorously jetted into the water flow of the raw water L through the orifice 5 and sufficiently stirred, so that the carbon dioxide gas G can be efficiently dissolved in the raw water L. is there. In particular, as shown in FIG. 2, in the configuration example in which the orifices 5 are eccentrically opposed and provided at two locations, the carbon dioxide gas G is sufficiently agitated by forming a vortex W in the flow of the raw water L. It will dissolve efficiently in L. Further, in the mixing portion, three or more orifices may be provided so as to face each other eccentrically. In addition, even in the configuration example in which one orifice is provided in the mixing unit, for example, by arranging the orifice so as to be ejected in a direction along the circumferential direction of the wall surface of the water channel, carbon dioxide gas can be applied to the wall surface of the water channel. As a result, a vortex is formed and sufficiently agitated, which is a preferred form of the present invention.

  Carbonated water produced at a preset concentration is discharged to the outside of the apparatus (face wash bowl, etc.) through this shower head etc., for example, since a carbonated water discharge part of the carbonated water discharge device X is equipped with a shower head. can do. Then, the practitioner can provide services such as shampooing to the practitioner with the carbonated water having the flow rate adjusted by the water stopcock F.

  Hereinafter, using the carbonated water discharge device X according to the present invention, a practitioner will briefly describe how to perform a shampoo by setting the concentration of carbonated water according to the dirt of the hair or scalp, etc. .

  The control base 4 of the carbonated water discharge device X includes a CPU, a ROM for storing software for operating the proportional control valve 3, a RAM for writing new information, and the like. In addition, a pressure sensor 1, a flow rate sensor 2, a switch provided on an operation panel for setting the concentration of carbonated water, and the like are connected to the input terminal of the control board 4. Connected to the output terminal of the control board 4 are a proportional control valve 3 and a group of light emitting diodes for displaying a value set by a switch on the operation panel.

  First, when the practitioner operates a selection switch for washing hair with carbonated water installed on the operation panel, the carbonated water discharge device X is turned on, and the pressure sensor 1, the flow sensor 2 and the like are activated and selected. A carbonated water indicator lamp, which is provided near the switch and is energized when carbonated water is selected with the selection switch, is turned on. Subsequently, the practitioner operates a concentration switch for setting the concentration of carbonated water to be generated. The concentration setting of the carbonated water by the concentration switch is, for example, in three steps. When the practitioner selects the third step (the highest concentration), the concentration indicator lamp provided near the concentration switch is 3 The fact that it is a tier is displayed. The density setting is not limited to three levels. Up to this point, the stop cock F is in a closed state.

  Next, the practitioner supplies water (hot water) from the supply source to the carbonated water discharge device X while adjusting the flow rate with the stop cock F. In the carbonated water discharge device X, the flow rate sensor 2 measures the flow rate through the water channel 20, and the flow rate measurement value is output from the flow rate sensor 2 and sent to the control board 4. At the same time, since carbon dioxide G is supplied from the carbon dioxide supply source to the gas passage 10 through the regulator, the gas pressure is measured by the pressure sensor 1, and the pressure measurement value is output from the pressure sensor 1 and sent to the control board 4. The

  In the control board 4, the difference between the pressure and the flow rate is obtained and calculated based on the two variables of the pressure measurement value measured by the pressure sensor 1 and the flow measurement value measured by the flow sensor 2, and the calculation is performed. One operation amount of the proportional control valve 3 having the carbonated water concentration (third stage concentration) set as a solution is determined, and the proportional control valve 3 is moved to an appropriate opening degree by the output. Then, the amount of carbon dioxide G flowing through the proportional control valve 3 after passing through the proportional control valve 3 whose opening degree is controlled is an amount of carbon dioxide having a preset concentration (third stage concentration). This is the amount of water produced.

  Carbon dioxide gas G, which is the amount by which carbonated water having a preset concentration is produced, is mixed with raw water L having a flow rate of water (hot water) adjusted by stop cock F through mixing unit 30, and stirred. It melts into carbonated water and is supplied to the shower head from its outlet. Thereby, the practitioner can perform hair washing with carbonated water.

  In the present invention, even when the carbon dioxide gas G in the cylinder becomes a little remaining and the gas pressure of the carbon dioxide gas G supplied to the gas passage 20 is lowered, even if the carbonated water discharge device X is operated, the control base 4 The amount of operation of the proportional control valve 3 corresponding to the decreased gas pressure is determined, and specifically, the proportional control valve 3 is moved so that the opening degree is relatively large, and the concentration of the preset concentration is set. Carbonated water can be produced. In addition, when the treatment person desires to wash the hair with a gentle flow rate, for example, when the stop cock F is squeezed, the operation amount of the proportional control valve 3 corresponding to this is determined, and specifically, Can move the proportional control valve 3 so that the opening degree becomes relatively small to produce carbonated water having a concentration as set in advance.

  In particular, based on two variables, a pressure measurement value measured by the pressure sensor 1 and a flow measurement value measured by the flow sensor 2, a difference between the pressure and the flow is obtained and calculated, and a proportional control valve is obtained as a solution. 3 is determined, and the proportional control valve 3 is moved based on the operation amount. Therefore, the change in the gas pressure of the carbon dioxide G supplied from the cylinder, the flow rate adjusted by the stop cock F In response to this change, carbonated water is supplied to the shower head from the outlet at a concentration as set in advance, and services such as shampooing can be provided.

  The carbonated water discharge device X according to the present invention can automatically stop its operation by a timer, for example, by adding a function for setting a set time to the control board 4 by a timer or the like. Thereafter, if the practitioner closes the stop cock F, the hair washing operation can be completed. If the patient wishes to wash with water (hot water) instead of carbonated water, the normal water washing is selected with the selection switch so that the carbonated water discharge device X is turned off without operating the flow sensor 2 or the like. In addition, normal hair washing can be performed using the water channel 20 of the carbonated water discharge device X, that is, without removing the carbonated water discharge device X from the stop cock F. Further, the concentration of carbonated water can be newly set through the operation panel in addition to a plurality of concentrations stored in advance in the control board 4. Since the practitioner sets the flow rate of the raw water L through the stop cock F, it is not necessary to set anything on the operation panel.

  Therefore, the carbonated water discharge device X according to the present invention can obtain a predetermined concentration of carbonated water even if the pressure of the gas to be supplied decreases as the carbon dioxide gas G in the cylinder becomes small, and the cylinder is discharged. The carbon dioxide G inside can be used effectively without waste. Furthermore, since the amount of carbon dioxide G mixed in the raw water L is controlled in accordance with the flow rate adjusted through the stop cock F, the flow rate of the carbonated water with a constant concentration is adjusted with the stop cock F that the user is familiar with. It becomes possible to provide it. That is, the present invention can flexibly cope with a change in the flow rate of the raw water L supplied from the stop cock and a change in the pressure of the carbon dioxide gas G supplied from the cylinder, and can provide an extremely convenient carbonated water discharge device. It becomes like this.

  Further, since the carbon dioxide G is injected through the orifice 5 arranged so as to be sufficiently stirred in the flow of the raw water L in the mixing section 30 of the carbonated water discharge device X, the carbon dioxide G is efficiently converted into the raw water L. It can be dissolved in water and can effectively give the action of carbonated water. Since the carbonated water discharge device X of the present invention does not require a cascade pump, the configuration is simple, the size can be reduced, the power consumption can be suppressed, and the introduction and running costs can be reduced. .

  Although one embodiment of the present invention has been described above as an example, the present invention can be modified in various ways without departing from the scope of the claims. For example, as described above, the carbonated water discharge device according to the present invention is provided with proportional control valves for pressure and flow rate, respectively, and the control base is proportional to the operation amount and flow rate of the proportional control valve for pressure. A configuration is possible in which the operation amount of each control valve is determined and moved to control the amount of carbon dioxide mixed in the raw water. This is because it is possible to produce carbonated water having a predetermined concentration that is set in advance by guiding the pressure to a predetermined amount of carbon dioxide gas through the proportional control valves for flow rate and flow rate. In addition, as for the small-diameter holes that allow the carbon dioxide gas to be mixed with the raw water in the mixing section, as long as sufficient stirring of the carbon dioxide gas is obtained, one or more small-diameter holes other than those described above can be used. It can be arranged in a form.
