Description

  The present invention relates to a liquid dispensing device, and particularly to a liquid detergent charging device mounted on an electric washing machine such as an electric washing machine, an electric dishwasher / dryer, and a local washing device for a toilet seat installed on a Western-style toilet. It is.

Conventionally, liquid detergents for electric washing machines such as electric washing machines, electric dishwashers and dryers that use liquid detergents, and local washing devices for toilet seats installed on Western-style toilets (for example, synthetic detergents for washing, synthetic surfactants) , Optical brightener, bleach, stain remover, softener, fragrance, depigmenting agent, disinfectant, detergent, deodorant, foaming agent, antifoaming agent, cleaning chemical synthesis agent, wrinkle removal agent, (Additives such as sterilizing liquid) The liquid detergent that the user puts in advance is put in a predetermined container, and the liquid detergent is electrically washed by water supply or mechanical method during the washing process of the electric washing equipment. Put it in the equipment. The amount of liquid detergent to be put into the electric cleaning equipment is determined by the user, but every time cleaning is performed, the liquid detergent must be placed in the designated container. As the detergent becomes more liquefied, the amount of liquid detergent can be automatically set according to the type of washing and the amount of washing for the convenience of the user's operation. A device that can be used for electric cleaning is required for a liquid detergent charging device mounted on an electric cleaning device.
When the electric washing machine is an electric washing machine, the washing item corresponds to the clothes to be washed, and when the electric washing machine is an electric dishwasher, the washing item corresponds to dishes such as dishes, and the toilet seat installed on the Western-style toilet bowl In the case of a local cleaning apparatus, the cleaning object corresponds to a toilet or a human body part to which dirt or the like adheres, and an accompanying function such as spraying a fragrance while cleaning.
In the present invention, unless otherwise noted, the examples in the case of an electric washing machine will be described, but in the case of an electric dishwasher, a local washing device for toilet seats installed on a Western-style toilet, etc. Can be applied as it is.

  According to the prior art investigation, for example, a technology related to a liquid detergent charging device that determines the amount of liquid detergent to be charged by opening the valve after pressurizing the liquid detergent filled in a predetermined container with a pressure pump. (For example, refer to Patent Document 1) Or, for example, by using an air pump, the air pressure in the sealed liquid detergent container is increased, and the liquid detergent in the liquid detergent container is pushed out from the liquid discharge port to be used as a washing tank of the electric washing device. A technique (for example, refer to Patent Document 2) related to a liquid detergent charging apparatus to be charged is disclosed. In these disclosed technologies, the user is required to fully fill the liquid detergent container and then completely seal the lid. However, if there is a problem in sealing the liquid detergent container, even if the liquid detergent container is pressurized with a pressure pump, the pressurized pressure may cause a leak (a pressure drop due to air leakage). Even if the pressure is the same, if the viscosity of the liquid detergent is different, the delivery speed is also different, so the amount of liquid detergent input may not be accurate. Further, the operating noise of the pressurizing pump that pressurizes the liquid detergent adversely affects the noise reduction of the entire electric cleaning device.

  In China, a liquid detergent container is provided at the bottom of the electric cleaning device, and the liquid detergent is sent to the water case at the upper part of the electric cleaning device by the extrusion pressure of the gear pump, and then mixed with water. There is also disclosed a technique related to a liquid detergent charging device that puts the liquid into a cleaning tank of an electric cleaning device. In this scheme, the gear pump is always in the liquid detergent, and when the liquid detergent is used, the liquid detergent is reduced from the liquid detergent container and drying (water evaporation, volatilization of the viscosity reducing agent, etc.) begins to occur. Phenomenon of solidification due to oxidation.If solidified by a valve or drive unit, the solidified substance is fixed and difficult to remove.) The viscosity change caused by overloading the feeding operation of the gear pump adversely affects it. There is a fear. And the noise caused by the overload operation of the gear pump adversely affects the noise reduction of the entire electric cleaning equipment. Moreover, due to variations in the viscosity of the liquid detergent, the accuracy of the amount of liquid detergent to be introduced may become a problem.

  Summarizing the above-disclosed techniques, in the pressurized delivery system using the liquid detergent pressure pump, the leakage problem caused by the lid of the liquid detergent container not being completely sealed and the change in the viscosity of the liquid detergent There are problems that affect accuracy. In the delivery system using the gear pump, there is a problem that the gear pump is clogged when the liquid detergent is solidified.

  Then, by providing a nozzle in the discharge pipe on the discharge side of the water absorption pump and providing a liquid detergent introduction pipe so as to merge immediately downstream thereof, the liquid detergent is sucked by the negative pressure generated by the water ejected from the nozzle. A technique (for example, see Patent Document 3) related to a liquid detergent charging device that is fed into an electric cleaning device while being mixed with water is also disclosed. This disclosed technology solves the problem of leakage due to incomplete sealing of the liquid detergent container in the pressurized delivery system by the pressure pump and the problem of clogging of the gear pump due to solidification of the liquid detergent in the delivery system by the gear pump. However, a water pump that can provide a constant pressure will be installed, and this cost may increase.

  Then, a negative pressure device based on the same principle as described above is used, but the technology related to the liquid detergent charging device using the negative pressure directly generated by tap water, not by the pressurization of the water absorption pump (for example, patent document) 4) is also disclosed. However, the magnitude of the negative pressure depends on the flow rate (water flow rate). When negative pressure is generated by supplying water from an electromagnetic water supply valve used in electric washing equipment, the range of variations in the generated negative pressure is large, and there is a problem that it is difficult to control the accuracy of liquid detergent charging.

  As disclosed in Example 2 of Patent Document 4, a metering case is provided between the negative pressure device and the liquid detergent container, the valve 1-1 and the valve 1-2 are closed, and the valve 1-3 and the valve 1- 4 is opened so that the inside of the measuring case is in a vacuum (negative pressure) state, and the valves 1-3 and 1-4 are closed, the valve 1-1 is opened, and the vacuum (negative pressure) of the measuring case is opened. ), The liquid detergent is allowed to flow into the measuring case, then the valve 1-1 is closed, the valve 1-2, the valve 1-3 and the valve 1-4 are opened, and the negative pressure generated by the water is used for measurement. The liquid detergent in the case is sent to the water case.

  Due to the magnitude of the water flow rate (water flow rate) disclosed in Example 1 of Patent Document 4, there is a problem in that the negative pressure generated varies and the measurement accuracy of the liquid detergent is affected. It was solved with. However, the second embodiment is a method of sucking the liquid detergent by the negative pressure remaining in the measurement case by filling the measurement case with the liquid detergent in a state where the negative pressure source and the measurement case are disconnected. . In the unlikely event that the negative pressure becomes insufficient, it becomes impossible to fill the measuring space to the full extent, resulting in a problem that the accuracy of the injection becomes out of order. Actually, when the weighing case is connected to this negative pressure source, it is impossible to create a vacuum inside the weighing case, so even if the weighing case is disconnected from the vacuum source, There is a negative pressure, but there is also a constant air pressure (ie there is a certain amount of air in the metering case). As the liquid detergent is filled, the space in the measuring case is reduced, the air in the measuring case is compressed, the negative pressure disappears, and then the liquid detergent cannot be filled. If there is a defect in the sealing of the weighing case, the problem becomes even worse. Moreover, since the liquid detergent with which the measuring case is filled is sucked into the water flow by negative pressure, when flowing from the valve to the pipe, a part of the liquid detergent remains in the pipe due to its viscosity. When these liquid detergents are solidified, the flow of the liquid detergent is hindered, and the effect of liquid detergent input is affected.

In terms of action (software),
First, when the electromagnetic water supply valve B is energized, water is passed through the suction generator, the water supply port B passes through the water supply port B, and the main water supply water is supplied to the cleaning tank of the electric cleaning device, A negative pressure is generated at the contraction port, and when the negative pressure is transmitted from the vacuum port to the constant volume chamber, the ball A moves to the valve seat D side of the link by the suction negative pressure, and the water outlet The constant volume chamber is closed and the constant volume chamber is becoming a negative pressure (vacuum). Next, when either the electromagnetic coil I or the electromagnetic coil II of the constant container is energized, the valve BI One of the valves BII is opened, and liquid detergent is sucked and filled into the constant volume chamber from either the liquid supply port BI or the liquid supply port BII, and the electromagnetic coil I and the electromagnetic coil II are filled after a specified time. When both the valve BI and the valve BII are closed, the suction filling of the liquid detergent is completed, but at the specified time due to the negative pressure. If the constant volume chamber is filled with liquid detergent within a short time, the ball C closes the valve seat C, the valve C is closed, and the liquid detergent suction is immediately stopped to complete the current filling operation (after full filling). Waiting state)

  When the electromagnetic water supply valve B is blacked out (or maintained energized) and the electromagnetic water supply valve A is energized, water passes from the water supply port to the through hole L, passes through the center orifice I of the fixed iron core I, and the guide. I passes through the inner peripheral part of I while washing the pipe of the constant volume chamber, passes through the center orifice II of the fixed iron core II, passes through the inner peripheral part of the guide II, and passes through the inner pipe of the constant volume chamber. The valve seat C is blocked by the ball C due to the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber. However, the liquid mixture of the liquid detergent and water filled with suction flows out from the outlet through the through hole F and out of the outlet, and passes through the water supply port A to wash the electric cleaning device from the opening of the water case. The tank will be supplied with a mixture of water and liquid detergent, and water from the electromagnetic water supply valve A When flows to volume chamber, a mixture of the constant volume chamber becomes reduced viscosity is diluted to a state close to the water low viscosity dilution water,

Finally, when both the electromagnetic water supply valve B and the electromagnetic water supply valve A are blacked out, the water that has been passed through the suction generator and the constant vessel is stopped and the water that has been in the constant volume chamber is suspended. When the water supply pressure from the electromagnetic water supply valve A disappears, the air enters the water outlet, the vacuum generation port, and the vacuum port in this order from the water supply B, and when the inside of the pipe is opened to the atmosphere, the valve seat C is opened. The blocked ball C moves away from the valve seat C (spontaneously falls), the atmosphere enters the constant volume chamber, and the low viscosity diluted water remaining in the constant volume chamber is discharged from the outlet. By draining and emptying the constant volume chamber, the next filling operation can be performed,
Two types of liquid detergents can be introduced by selecting the operation of either the electromagnetic coil I or the electromagnetic coil II of the constant container.

It is possible to improve the measurement accuracy of the amount of liquid detergent to be charged while eliminating the expensive pump from the liquid detergent charging device for charging the liquid detergent filled in the container into the washing tub by pump pressurization.

Consists of
FIG. 3a (or FIG. 3b) shows an overall view (perspective view) showing the configuration of the liquid detergent charging device of Example 1 of the present invention.

In Example 1 of the present invention, the electromagnetic water supply valve 1 is used for main injection of water into the washing tank (electromagnetic water supply valve B), for adding a mixture of liquid detergent and water (electromagnetic water supply valve A), Adopted dual electromagnetic water supply valve, but for cleaning water main water injection (electromagnetic water supply valve B), for adding liquid mixture of liquid detergent and water (electromagnetic water supply valve A), for rinse water rinsing water injection (tentatively electromagnetic water supply valve) C)), a triple-type electromagnetic water supply valve may be used, or for cleaning water main water injection (electromagnetic water supply valve B), for adding a mixture of liquid detergent and water (electromagnetic water supply valve A) A quadruple electromagnetic water supply valve or the like may be employed for washing water rinsing water injection (tentatively referred to as electromagnetic water supply valve C) and a minute amount (spraying) water injection (tentatively referred to as electromagnetic water supply valve D) for the drying process.

A valve, a quadruple electromagnetic water supply valve, or a five-pole electromagnetic water supply valve may be employed.
For example, when rinsing and rinsing with 5 liters of washing water per minute are desired, for example, a water outlet from which water from the water inlet 101 flows out by opening and closing the electromagnetic water supply valve C may be connected to the water case 5.
The water (water injection) from the electromagnetic water supply valve A not only creates a liquid mixture of liquid detergent and water, but also serves to clean the constant volume chamber 3013 (dilution of liquid detergent, concentration reduction).

As shown in FIGS. 4 and 5, the body 301 of the fixed container 3 according to the first embodiment of the present invention is formed of a synthetic resin molding member (for example, polypropylene resin), and has a water outlet 312 and a water inlet on the outer periphery. A body of a container body having a valve seat A30131 that is a conduit port that communicates with the water outlet 312 and a valve seat C30133 that is a conduit port that communicates with the vacuum port 3017 on the inner periphery. A3011,
Molded with a synthetic resin molding member (for example, polypropylene resin), provided with a liquid supply port 3016 on the outer surface side and a valve seat B30132 which is a conduit port communicating with the liquid supply port 3016 on the inner surface side and the density of water A lid body B3012 having a base B30121 that can accommodate the low valve ball C310;
Are combined to form.
Specifically, the body A 3011 and the body B 3012 are joined by a screw fastening method (for example, other connection methods such as press fitting, caulking, welding, welding, etc.), and in the middle of the joining portion, In order to maintain watertightness, an O-ring (for example, an elastic member such as silicon rubber) or the like is attached.
The body A3011 according to the first embodiment of the present invention is formed of two parts, that is, a part having the water outlet 312 and a part having the water supply port 313 and the vacuum port 3017. good.

Inside the body 301, a constant volume chamber 3013 is formed, which is a space (for example, a filling capacity of 20 cc) that can be filled with a liquid detergent (a predetermined usage amount) necessary for one cleaning operation.
Further, a detergent outflow on / off valve is provided inside the body 301 for supplying water from the constant volume chamber 3013 to the water case 5, and more specifically, a valve A302 for opening and closing the water outlet 312 and the constant volume chamber 3013. In addition, a detergent inflow opening / closing valve is provided for delivering the liquid detergent in the liquid detergent tank 2 to the constant volume chamber 3013. Specifically, a valve B303 for opening / closing the liquid supply port 3016 and the constant volume chamber 3013 is provided. And an open / close valve for releasing air from the constant volume chamber 3013, more specifically, a valve C304 for opening and closing the vacuum port 3017 and the constant volume chamber 3013.

The valve C304 includes the valve seat C30133, and the ball C310 provided between the base B30121 and the valve seat C30133.
The valve seat C30133 may be formed of a rubber material or a synthetic resin molded member (for example, polypropylene resin). Further, it may be a separate part from the body A3011 or an integral part with the body A3011.
The base B30121 is provided on the body B3012 so as to face the valve seat C30133.
The ball C310 was formed of a synthetic resin molding member (for example, a polyester resin) having a density lower than that of water so that it floats on water or a liquid detergent. By opening and closing the valve seat C30133 with the ball C310, the vacuum port 3017 and the constant volume chamber 3013 are opened and closed (line communication and line blockage).
The vacuum port 3017 may be in an extreme vacuum (negative pressure) state when the valve C304 is closed by filling with a liquid detergent. For this reason, it is expected that the ball C310 sticks excessively to the valve seat C30133 (in the worst case, bite occurs), and the valve opening operation due to the natural fall accompanying the release to the atmosphere is hindered. In order to prevent such a state, a check valve capable of flowing into the atmosphere in a specified extreme vacuum (negative pressure) state may be provided between the valve seat C30133 and the vacuum port 3017.

The suction generator 4 has a water supply port 401, a water discharge port 402 communicating with the water supply port 401, and a reduced and enlarged cross section in a part of the pipe between the water supply port 401 and the water supply port 402. In detail, it is good also as the shape which applied the nozzle, the orifice, the venturi pipe etc. which are used when measuring the pressure difference p1-p2 by reducing the diameter of the upstream side of the pipe and expanding the diameter of the downstream side. This is a so-called aspirator (inhaler) provided with a contraction port 403 provided with a vacuum generation port 404 communicating with the contraction port 403.
Specifically, when the fluid (water, air) passes through a portion where the flow path called the venturi is restricted, the flow velocity of the fluid increases due to the venturi effect, and the pressure decreases from the fluid pressure (the degree of decrease is understood by Bernoulli's theorem) ) The phenomenon occurs. The venturi effect is a mechanism that generates a lower pressure than the low speed portion by increasing the flow velocity by restricting the flow of fluid. The suction generator 4 applies this venturi effect, and is formed by integral molding with a synthetic resin molding member (for example, polypropylene resin).
In the first embodiment of the present invention, the suction generator 4 is formed as an independent part and connected to the water case 5, but may be a part of the water case 5.

As for the connection between the pipe openings, the pipes and the bond (adhesive / primer) may be directly coupled by a screw fastening method (for example, other connection methods such as press fitting, caulking, welding, welding, etc.). The water outlet A102 of the electromagnetic water supply valve A is connected to the water supply port 313 of the constant vessel 3 by using a binding aid (watertight retaining agent) such as a binding (hose retaining band) or the like, and the electromagnetic water supply valve The water outlet B103 of B is connected to the water supply port 401 of the suction generator 4, and the liquid supply port 3016 of the constant vessel 3 is connected to the detergent outlet 201 of the liquid detergent tank 2, and the constant vessel 3 The vacuum port 3017 is connected to the vacuum generation port 404 of the suction generator 4, the water outlet 312 of the constant vessel 3 is connected to the water supply port A 501 of the water case 5, and the suction generator 4 The water outlet 402 is the water supply port B502 of the water case 5. It is connected.
In the case of direct coupling, if necessary, an O-ring (for example, an elastic member such as silicon rubber) or the like may be attached in the middle of each connection portion in order to maintain watertightness.

The water case 5 is formed of a synthetic resin molded member (for example, polypropylene resin), but can be separated into one part of a cleaning tank of an electric cleaning device.
In the opening of the water case 5, a drawer case that can store a powder detergent or a consumer-friendly softener can be placed.
By pouring water flowing out from the water supply port B502 into the drawer case, the powder detergent, the softener preferred by the consumer, and the like are dissolved, and the mixed solution is supplied to the cleaning tank of the electric cleaning device.

As shown in FIGS. 9 and 11, if the electromagnetic water supply valve A is weakly blocked due to the low water pressure of tap water, a check valve 6 may be provided at the water supply port 313.
The check valve 6 is provided with a base 604 and a valve core 601. The base 604 includes a small ring 6043 surrounded by the ring 6041 and the ring 6041. A fluid through hole 6042 is provided between the small ring 6043 and the ring 6041. A guide for the valve core 601 is in the small ring 6043, a spring 602 is provided outside the guide for the valve core 601, and an O-ring 603 is provided on the valve core 601.
Further, as shown in FIGS. 10 and 11, when the electromagnetic water supply valve B is weakly blocked due to the low water pressure of tap water, a check valve 6 may be provided at the water supply port 401.

The operation (software) of the liquid detergent charging device according to the first embodiment of the present invention will be described.
When a user uses an electric washing apparatus (for example, an electric washing machine) equipped with the liquid detergent charging device according to the first embodiment of the present invention, an amount of liquid detergent (for example, a laundry detergent, It is necessary to put the detergent for washing with softener in the liquid detergent tank 2.
In this state, first, when the electromagnetic water supply valve B is energized, water is passed through the suction generator 4, water passes through the water supply port B 502, and the water is supplied from the open port 503 of the water case 5 to the cleaning tank of the electric cleaning device. Main water supply is performed.
At this time, the state of each valve at the initial stage before adding the liquid detergent is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve Constant volume chamber valve A: Opened Constant volume chamber valve B: Closed Constant volume chamber valve C: Opened Constant volume chamber Since there is no water in 3013, the ball C310 falls to the base B30121 due to its own weight, and the valve C304 is opened.
Although negative pressure is generated at the contraction port 403 by passing water through the suction generator 4 and the atmosphere (air) in the constant container 3013 is sucked through the valve C304, the valve A302 is opened. Therefore, nothing happens because the water outlet 312 and the water supply port A501 of the water case 5 are connected to the atmosphere. Further, since the valve B303 is in a closed state, the liquid detergent in the liquid detergent tank 2 does not flow into the constant volume chamber 3013.

Next, when the valve B303 is opened and the valve A302 is closed, the constant volume chamber 3013 is depressurized (toward the vacuum) from the vacuum port 3017 due to the negative pressure generated at the contraction port 403. Then, liquid detergent is sucked and filled into the constant volume chamber 3013 from the liquid supply port 3016.
The state of each valve when filling with liquid detergent is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Open valve Constant volume chamber valve A: Closed Constant volume chamber valve B: Open constant volume chamber valve C: Open valve For details, open valve B303 Then, since the liquid supply port 3016 and the constant volume chamber 3013 are communicated with each other, the liquid detergent in the liquid detergent tank 2 can flow into the constant volume chamber 3013.
When the valve A302 is closed, the water supply port 313 is closed by the electromagnetic water supply valve A, so that the conduit between the water outlet 312 and the constant volume chamber 3013 is closed and at the same time the fixed water supply port 313 is closed. The inside of the chamber 3013 becomes negative pressure (vacuum), and the liquid detergent in the liquid detergent tank 2 is sucked into the constant volume chamber 3013 from the liquid supply port 3016 due to the negative pressure.

When the valve B303 is closed and the valve A302 is opened after a specified time (for example, 18 seconds), the liquid detergent suction is forcibly terminated, but the specified time (for example, 18 If the constant volume chamber 3013 is filled with liquid detergent within a second), the ball C310 closes the valve seat C30133 and the valve C304 is closed, and the liquid detergent suction is immediately stopped, The operation is complete. (Transfers to the standby state after full before the forced filling of the liquid detergent suction.)
The state of each valve in the standby state after full at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Open valve with constant volume chamber A: Closed valve Valve with constant volume chamber B: Open valve with constant volume chamber C: Valve closed

The state of each valve when the suction of liquid detergent is forcibly terminated before it is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Open valve Constant volume chamber valve A: Closed Constant volume chamber valve B: Closed Constant volume chamber valve C: Opened

Figure 1 shows the relationship between water pressure and negative pressure. Fig. 2 shows the relationship between the filling time and the filling amount of liquid detergent that can be filled in the constant container 3013 under different negative pressures. P1 in FIG. 2 is a negative pressure at a high water pressure (for example, 1.0 MPa), and P2 is a negative pressure at a low water pressure (for example, 0.02 MPa).
Due to variations in the water pressure of tap water, the speed at which the water flows changes, the negative pressure generated by the suction generator 4 also changes significantly, and the speed at which the liquid detergent flows into the constant volume chamber 3013 also changes. For example, in the case of the constant volume chamber 3013 having a filling capacity of 20 cc, when the water pressure reaches, for example, 0.02 MPa (low water pressure), it takes about 20 seconds to fill the constant volume chamber 3013. When 1.0 MPa (high water pressure) is reached, it takes about 5 seconds to fill the constant volume chamber 3013.
When the time from closing to opening of the valve A302 is set to the worst 20 seconds, when the water pressure becomes, for example, 1.0 MPa, the first five chambers are set to a negative pressure (vacuum). Although the valve C is open for 2 seconds, when the constant volume chamber 3013 becomes negative pressure (vacuum), the liquid detergent is filled up in 5 seconds, and the buoyancy of the liquid detergent Since C is closed and negative pressure does not affect the constant volume chamber 3013, the liquid detergent in the liquid detergent tank 2 cannot enter the constant volume chamber 3013.

Then, when the electromagnetic water supply valve B is blacked out (non-energized) or kept energized, and the electromagnetic water supply valve A is energized, water is supplied (injected) into the constant volume chamber 3013, and the constant volume chamber 3013 is filled with water. The mixture of the liquid detergent and water filled with suction is maintained while the valve C30133 is closed by the ball C310 (forced closing when the valve is opened) by the water flow pressure from the electromagnetic water supply valve A applied. The mixture of water and liquid detergent is supplied from the opening 503 of the water case 5 to the washing tank of the electric washing device through the water supply port A501 through the water outlet 312.
Further, when water from the electromagnetic water supply valve A flows into the constant volume chamber 3013, the liquid mixture in the constant volume chamber 3013 is diluted to a state close to water, the viscosity decreases, and low-viscosity diluted water (finally tap water). Thus, the inside of the constant volume chamber 3013 and the valve A302 are cleaned cleanly.
The state of each valve in the water injection state at this time is as follows.
Electromagnetic water supply valve A: Open valve Electromagnetic water supply valve B: Closed or open valve Constant volume chamber valve A: Open constant volume chamber valve B: Closed Constant volume chamber valve C: Closed valve

Finally, when both the electromagnetic water supply valve B and the electromagnetic water supply valve A are powered off (no power supply), the water that has been passed through the suction generator 4 and the constant vessel 3 stops. When the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber 3013 disappears, the atmosphere enters the water outlet 402, the vacuum generation port 404, and the vacuum port 3017 in order from the water supply port B502. When the inside of the pipe is opened to the atmosphere, the ball C310 that has blocked the valve seat C30133 naturally falls and leaves the valve seat C30133, and the atmosphere enters the constant volume chamber 3013, and the constant volume chamber 3013 is released. The low-viscosity diluted water remaining in the volume chamber 3013 is drained from the water outlet 312 and the inside of the constant volume chamber 3013 becomes empty (empty).
Then, the next filling operation can be performed.
The state of each valve during drainage of the constant volume chamber 3013 at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Closed valve Constant volume chamber valve A: Open constant volume chamber valve B: Closed Constant volume chamber valve C: Open valve

Although the expression that the inside of the constant volume chamber 3013 is empty (empty) due to drainage is taken, actually, depending on the position of the water supply port A501 of the water case 5 and the position of the water outlet 312 of the constant volume chamber 3013. In some cases, the water supply port A501 and the water outlet 312 are not completely emptied because of the pipe connection.
As shown in FIG. 8a, when the water supply port A501 is at a horizontal position with the water outlet 312 or lower than the position, the water supply port A501 is often almost empty.
If the water supply port A501 is higher than the water outlet 312 as shown in FIG. 8b, it may not be completely empty. Reference numeral 30135 represents the actual filling capacity or the amount of water that can be drained.

The liquid detergent corresponding to the volume of the constant volume chamber 3013 (the volume of the substantial filling capacity 30135, for example, 20 cc) can be charged by a single operation. The liquid detergent of n times the volume (n = 2, 3, 4,..., Integer) can be added by two additional operations.
Further, the volume of the constant volume chamber 3013 can be changed. For example, when it is set to 10 cc, 10 cc or n times (n = 2, 3, 4,..., Integer) liquid detergent can be introduced.

  In the liquid detergent charging apparatus of Example 1 of the present invention, the state of each valve in each process of liquid detergent charging is shown in Table 1 below.

In the liquid detergent charging apparatus of Example 1 of the present invention, the constant volume chamber regardless of whether the tap water has a minimum value (for example, 0.02 MPa) or a maximum value (for example, 1.0 MPa). It is characterized in that a liquid detergent n times the volume of 3013 (n = 2, 3, 4,..., Integer) can be accurately charged.
Further, the present invention can be applied not only to the addition of liquid detergent but also to the addition of other liquid agents (for example, bleaching agents, softening agents, sterilizing liquids, etc.)

Details of a further configuration (hardware) of the constant container 3 of the liquid detergent charging device according to the first embodiment of the present invention will be described with reference to FIGS.
In order to drive the valve A302 and the valve B303 in an interlocking manner and drive them with electromagnetic force, a guide 3018 is provided on the outer periphery of the body 301 as a conduit communicating with the water outlet 312 and communicating with the valve seat A30131. An electromagnetic coil 305 having a yoke is provided on the outer peripheral portion of the guide 3018. A fixed iron core 306 coupled to the yoke is provided on the inner peripheral portion of the guide 3018, and the valve seat B30132 passes through the valve seat A30131. A movable iron core 307 that has a contraction portion 3071 that is an extension rod extending to the guide 3018 and that can move within the guide 3018; and a spring 309 between the fixed iron core 306 and the movable iron core 307; An amateur seat 308 that is a valve body is provided at an end of the portion 3071.
The first embodiment of the present invention has a so-called direct acting valve type three-way valve configuration.

Specifically, the water outlet 312 is installed between the guide 3018 and the valve seat A 30131 which is a conduit port of the guide 3018, and the valve seat B 30132 which is a conduit port communicating with the liquid supply port 3016 is It installed so that it might oppose seat A30131, and the armature seat 308 was installed between this valve seat B30132 and this valve seat A30131.
The valve B303 is opened and closed when the front end 3081 of the armature seat 308 moves toward and away from the valve seat B30132.
The valve A302 is opened and closed when the rear end 3082 of the amateur seat 308 moves away from and contacts the valve seat A30131.
The opening and closing of the valve B and the opening and closing of the valve A are interlocked as follows.
When the valve B (one) is opened, the valve A (the other) is closed, and when the valve B (one) is closed, the valve A (the other) is opened.
Alternatively, when the valve A (one) is opened, the valve B (the other) is closed, and when the valve A (one) is closed, the valve B (the other) is opened.

These actions (software) will be described.
At the time of a power failure (non-energization) of the electromagnetic coil 305, since the spring 309 is extended between the fixed iron core 306 and the movable iron core 307, the armature seat 308 closes the valve seat B30132. The valve B303 is closed to close the liquid supply port 3016 and the constant volume chamber 3013.
In conjunction with this, the armature seat 308 is separated from the valve seat A30131, so that the valve A302 is opened, and the water outlet 312 and the constant volume chamber 3013 are in communication with each other.

When the movable iron core 307 moves to the fixed iron core 306 side by the attractive force generated by energization of the electromagnetic coil 305, the spring 309 between the fixed iron core 306 and the movable iron core 307 is contracted. The seat 308 is separated from the valve seat B30132, and the valve B303 is opened, so that the liquid supply port 3016 and the constant volume chamber 3013 communicate with each other through a pipe line.
In conjunction with this, the armature seat 308 closes the valve seat A30131 and closes the valve A302 to close the water outlet 312 and the constant volume chamber 3013.

Are combined to form.
Specifically, the body AI 30111 and the body BI 30122, the body AI 30111 and the connecting body, the body AI 30111 and the link 311, the link 311 and the lid 315 are screwed (for example, press-fitting) Other connection methods such as caulking, welding, welding, etc. may be used.) In the middle of each connecting portion, an O-ring (for example, an elastic member such as silicon rubber) is used to maintain watertightness. Is attached.

A constant volume chamber 3013 is formed in the body 301. The constant volume chamber 3013 is a space (for example, a filling capacity of 20 cc) that can be filled with a liquid detergent (predetermined amount of use) necessary for one washing (or rinsing, finishing) operation. The
Further, a detergent outflow on / off valve is provided inside the body 301 to feed water from the constant volume chamber 3013 to the water case 5, and more specifically, a valve A 302 that opens and closes the water outlet 312 and the constant volume chamber 3013. In addition, a detergent I inflow opening / closing valve is provided to send the liquid detergent I in the liquid detergent tank 2 to the constant volume chamber 3013. Specifically, the liquid supply port BI3016A and the constant volume chamber 3013 are opened and closed. A valve BI is provided, and a detergent II inflow opening / closing valve is provided to send the liquid detergent II of the liquid detergent tank 2 to the constant volume chamber 3013. Specifically, the liquid supply port BII3016B and the constant volume chamber 3013 are provided. A valve BII for opening and closing is provided, and an open / close valve for releasing air from the constant volume chamber 3013 is provided. Specifically, a valve C304 for opening and closing the vacuum port 3017 and the constant volume chamber 3013 is provided. ing.

The valve A302 includes a ball A314 of a valve body placed in a concave space of the link 311 and a valve seat D3112 on which a valve body housed in a space in which the valve seat D3112 of the link 311 can be accommodated.
The valve seat D3112 may be formed of a rubber material or a synthetic resin molded member (for example, polypropylene resin).
The ball A314 was formed of a synthetic resin molded member (for example, polyester resin) having a density lower than that of water so that it floats on water or liquid detergent.
By opening and closing the valve seat D3112 with the ball A314, the constant volume chamber 3013 is opened and closed (communication and closing) via the water outlet 312 and the through hole F3151.

The valve C304 includes the valve seat C30133, and a valve body ball C310 provided between the valve seat C30133 and a base A30113 in which the ball valve body can be accommodated.
The valve seat C30133 may be formed of a rubber material or a synthetic resin molded member (for example, polypropylene resin). The connecting body may be a separate part or the connecting body and an integral part.
A base A30113 that can accommodate the ball valve body is provided on the body AI30111 so as to face the valve seat C30133.
The ball C310 was formed of a synthetic resin molding member (for example, a polyester resin) having a density lower than that of water so that it floats on water or a liquid detergent. By opening and closing the valve seat C30133 with the ball C310, the vacuum port 3017 and the constant volume chamber 3013 are opened and closed (line communication and line blockage).
The vacuum port 3017 may be in an extreme vacuum (negative pressure) state when the valve C304 is closed by filling with a liquid detergent. For this reason, it is expected that the ball C310 sticks excessively to the valve seat C30133 (in the worst case, bite occurs), and the valve opening operation due to the natural fall accompanying the release to the atmosphere is hindered. In order to prevent such a state, a check valve capable of flowing into the atmosphere in a specified extreme vacuum (negative pressure) state may be provided between the valve seat C30133 and the vacuum port 3017.

The suction generator 4 has a water supply port 401, a water discharge port 402 communicating with the water supply port 401, and a reduced and enlarged cross section in a part of the pipe between the water supply port 401 and the water supply port 402. In detail, it is good also as the shape which applied the nozzle, the orifice, the venturi pipe etc. which are used when measuring the pressure difference p1-p2 by reducing the diameter of the upstream side of the pipe and expanding the diameter of the downstream side. This is a so-called aspirator (inhaler) provided with a contraction port 403 provided with a vacuum generation port 404 communicating with the contraction port 403.
Specifically, when the fluid (water, air) passes through a portion where the flow path called the venturi is restricted, the flow velocity of the fluid increases due to the venturi effect, and the pressure decreases from the fluid pressure (the degree of decrease is understood by Bernoulli's theorem) ) The phenomenon occurs. The venturi effect is a mechanism that generates a lower pressure than the low speed portion by increasing the flow velocity by restricting the flow of fluid. The suction generator 4 applies this venturi effect, and is formed by integral molding with a synthetic resin molding member (for example, polypropylene resin).
In the second embodiment of the present invention, the suction generator 4 is formed as an independent part and connected to the water case 5, but it may be a part of the water case 5.

As for the connection between the pipe openings, the pipes and the bond (adhesive / primer) may be directly coupled by a screw fastening method (for example, other connection methods such as press fitting, caulking, welding, welding, etc.). The water outlet A102 of the electromagnetic water supply valve A is connected to the water supply port 313 of the constant vessel 3 by using a binding aid (watertight retaining agent) such as a binding (hose retaining band) or the like, and the electromagnetic water supply valve The water outlet B103 of B is connected to the water supply port 401 of the suction generator 4, and the liquid supply port I3016A of the constant vessel 3 is connected to the detergent I outlet 202 of the liquid detergent tank 2, and the constant vessel 3 is connected to the detergent II outlet 203 of the liquid detergent tank 2, and the vacuum port 3017 of the constant container 3 is connected to the vacuum generation port 404 of the suction generator 4. The water outlet 312 of the container 3 is the water supply of the water case 5. The water outlet 402 of the suction generator 4 is connected to the water supply port B 502 of the water case 5.
In the case of direct coupling, if necessary, an O-ring (for example, an elastic member such as silicon rubber) or the like may be attached in the middle of each connection portion in order to maintain watertightness.

The water case 5 is formed of a synthetic resin molded member (for example, polypropylene resin), but can be separated into one part of a cleaning tank of an electric cleaning device.
In the opening 503 of the water case 5, a drawer case that can store a powder detergent or a consumer-friendly softener can be placed.
By pouring water flowing out from the water supply port B502 into the drawer case, the powder detergent, the softener preferred by the consumer, and the like are dissolved, and the mixed solution is supplied to the cleaning tank of the electric cleaning device.

As shown in FIGS. 9 and 11, if the electromagnetic water supply valve A is weakly blocked due to the low water pressure of tap water, a check valve 6 may be provided at the water supply port 313.
The check valve 6 is provided with a base 604 and a valve core 601. The base 604 includes a small ring 6043 surrounded by the ring 6041 and the ring 6041. A fluid through hole 6042 is provided between the small ring 6043 and the ring 6041. A guide for the valve core 601 is in the small ring 6043, a spring 602 is provided outside the guide for the valve core 601, and an O-ring 603 is provided on the valve core 601.
Further, as shown in FIGS. 10 and 11, when the electromagnetic water supply valve B is weakly blocked due to the low water pressure of tap water, a check valve 6 may be provided at the water supply port 401.

The operation (software) of the liquid detergent charging device according to the second embodiment of the present invention will be described.
When a user uses an electric cleaning device (for example, an electric washing machine) equipped with the liquid detergent charging device according to the second embodiment of the present invention, an amount of liquid detergent I (for example, a laundry detergent) that can be washed several times in advance is used. ) And an amount of liquid detergent II (for example, bleach, softener) that can be rinsed (finished) several times in advance must be placed in the liquid detergent tank 2.
In this state, first, when the electromagnetic water supply valve B is energized, water is passed through the suction generator 4, water passes through the water supply port B 502, and the water is supplied from the open port 503 of the water case 5 to the cleaning tank of the electric cleaning device. Main water supply is performed.
At this time, the state of each valve at the initial stage before adding the liquid detergent is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Opened Constant volume chamber valve BI: Closed Constant volume chamber valve BII: Closed Constant volume chamber valve C: Opened Since there is no water in the constant volume chamber 3013 of the constant container 3, the ball C310 falls to the base A30113 in which the ball valve body can be stored due to its own weight, and the valve C304 is opened.
When negative pressure is generated at the contraction port 403 due to water flow in the suction generator 4 and the atmosphere (air) in the constant container 3013 is sucked from the vacuum port 3017 via the valve C304, The ball A314 is moved to the valve seat D3112 side of the link 311 by negative pressure due to negative pressure, the valve A302 is closed, the water outlet 312 and the constant volume chamber 3013 are closed, and the constant vessel The pressure inside 3013 is reduced to a negative pressure (vacuum). However, since the valve BI is in the closed state, the liquid detergent I in the liquid detergent tank 2 does not flow into the constant volume chamber 3013. Similarly, the liquid detergent II in the liquid detergent tank 2 does not flow into the constant volume chamber 3013 because the valve BII is in a closed state.

Next, an operation when the liquid detergent I is charged in the washing process will be described.
When the electromagnetic coil I305A of the constant container 3 is energized, the valve BI is opened, and the liquid detergent I is supplied from the liquid supply port BI3016A to the constant volume due to the negative pressure (vacuum) in the constant volume chamber 3013. The chamber 3013 is filled with suction.
The state of each valve at the time of filling liquid detergent I at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed constant volume chamber valve BI: Opened Constant volume chamber valve BII: Closed constant volume chamber valve C: Opened

When both the electromagnetic coil I305A and the electromagnetic coil II305B are blacked out after a specified time (for example, 19 seconds) and both the valve BI and the valve BII are closed, the suction filling of the liquid detergent I is forcibly terminated. When the constant volume chamber 3013 is filled with the liquid detergent I within the specified time (for example, 19 seconds) due to the pressure, the ball C310 closes the valve seat C30133 and the valve C304 is closed. Suction is immediately stopped and the current filling operation is completed. (Transfer to standby state after liquid detergent I is full before forced termination of suction filling with liquid detergent I.)
The state of each valve in the standby state after the liquid detergent I is full at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed constant volume chamber valve BI: Opened Constant volume chamber valve BII: Closed constant volume chamber valve C: Closed valve

The state of each valve when the suction of liquid detergent I is forcibly terminated before it is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Closed valve Valve of constant volume chamber C: Opened valve

Here, the operation in the case of performing the charging operation of the liquid detergent II in the rinsing (finishing) step will be described.
When the electromagnetic coil II 305B of the constant container 3 is energized, the valve BII is opened, and the liquid detergent II is supplied from the liquid supply port BII 3016B to the constant volume due to the negative pressure (vacuum) in the constant volume chamber 3013. The chamber 3013 is filled with suction.
The state of each valve at the time of filling liquid detergent II at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Opened valve Valve of constant volume chamber C: Opened valve

When both the electromagnetic coil I305A and the electromagnetic coil II305B are blacked out after a specified time (for example, 19 seconds) and both the valve BI and the valve BII are closed, the suction filling of the liquid detergent II is forcibly terminated. When the constant volume chamber 3013 is filled with the liquid detergent II within the specified time (for example, 19 seconds) due to pressure, the ball C310 closes the valve seat C30133 and the valve C304 is closed, thereby liquid detergent II. Suction is immediately stopped and the current filling operation is completed. (Transfer to standby state after liquid detergent II is full before forced termination of liquid detergent II suction filling.)
The status of each valve in the standby state after the liquid detergent II is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed Constant volume chamber valve BI: Closed Constant volume chamber valve BII: Opened Constant volume chamber valve C: Closed valve

The state of each valve when the suction filling of Liquid Detergent II is forcibly terminated before it is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Closed valve Valve of constant volume chamber C: Opened valve

Then, when the electromagnetic water supply valve B is blacked out (non-energized) or maintained energized and the electromagnetic water supply valve A is energized, water is passed (injected) into the constant volume chamber 3013 and applied to the constant volume chamber 3013. While the valve seat C30133 is kept closed by the ball C310 due to the water flow pressure from the electromagnetic water supply valve A (forced closing when the valve is open), the liquid mixture of the suction-filled liquid detergent and water flows in the flow. The mixture of water and liquid detergent is supplied from the outlet 3014 through the through hole F3151 and out of the water outlet 312 through the water supply port A501 to the cleaning tank of the electric cleaning device from the opening 503 of the water case 5. Is called.
Further, when water from the electromagnetic water supply valve A flows into the constant volume chamber 3013, the liquid mixture in the constant volume chamber 3013 is diluted to a state close to water, the viscosity decreases, and low-viscosity diluted water (finally tap water). Through the center orifice I3061 of the fixed iron core I306A, through the through hole L3111, through the through hole F3151, through the valve A302, and through the valve A302. It is possible to prevent the liquid detergent from solidifying by flowing out from the water port 312.
Further, it passes through the inner peripheral part of the guide II 3018B, passes through the center orifice II 3062 of the fixed iron core II 306B, passes through the through hole L3111, passes through the through hole F3151, passes through the valve A302, and flows out from the water outlet 312. Solidification of the liquid detergent can be prevented.
The state of each valve in the water injection state at this time is as follows.
Electromagnetic water supply valve A: Open valve Electromagnetic water supply valve B: Valve closed or open Constant volume chamber valve A: Open valve Constant volume valve BI: Closed Constant volume chamber valve BII: Closed constant volume chamber valve C : Valve closed

Finally, when both the electromagnetic water supply valve B and the electromagnetic water supply valve A are powered off (no power supply), the water that has been passed through the suction generator 4 and the constant vessel 3 stops. When the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber 3013 disappears, the atmosphere enters the water outlet 402, the vacuum generation port 404, and the vacuum port 3017 in order from the water supply port B502. When the inside of the pipe is opened to the atmosphere, the ball C310 that has blocked the valve seat C30133 naturally falls and leaves the valve seat C30133, and the atmosphere enters the constant volume chamber 3013, and the constant volume chamber 3013 is released. The low-viscosity diluted water remaining in the volume chamber 3013 is drained from the water outlet 312 and the inside of the constant volume chamber 3013 becomes empty (empty).
Then, the next filling operation can be performed.
The state of each valve during drainage of the constant volume chamber 3013 at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Closed valve Constant volume chamber valve A: Open constant volume chamber valve BI: Closed Constant volume chamber valve BII: Closed constant volume chamber valve C: Opened valve Thus, two types of liquid detergents (liquid detergent I and liquid detergent II) can be charged by selecting the operation of either the electromagnetic coil I305A or the electromagnetic coil II305B of the fixed container 3.
In the liquid detergent charging device according to the second embodiment of the present invention, the switching mechanism of the two types of liquid detergent is a direct acting valve type electromagnetic three-way valve. For example, even if the configuration of a direct acting valve type electromagnetic two way valve is used. The drive system of the valve is not particularly limited to an electromagnetic type, an electric type, a manual type, or the like.
In addition, for example, two or more independent constant containers equipped with one direct acting valve type electromagnetic two-way valve may be combined, and a plurality of valves B can be mounted on the constant container 3. It is good also as a fixed container carrying the switching mechanism of three or more types of liquid detergents.

Although the expression that the inside of the constant volume chamber 3013 is empty (empty) due to drainage is taken, actually, depending on the position of the water supply port A501 of the water case 5 and the position of the water outlet 312 of the constant volume chamber 3013. In some cases, the water supply port A501 and the water outlet 312 are not completely emptied because of the pipe connection.
As shown in FIG. 8a, when the water supply port A501 is at a horizontal position with the water outlet 312 or lower than the position, the water supply port A501 is often almost empty.
If the water supply port A501 is higher than the water outlet 312 as shown in FIG. 8b, it may not be completely empty. Reference numeral 30135 represents the actual filling capacity or the amount of water that can be drained.

  Liquid detergent (liquid detergent I and liquid detergent II) corresponding to the volume of the constant volume chamber 3013 (for example, 20 cc in the volume of the substantial filling capacity 30135) can be charged in one operation. When the liquid detergent I is to be charged, the liquid detergent I having a volume n times (n = 2, 3, 4,..., An integer) can be charged by two, three,. Similarly, when a large amount of liquid detergent II is to be added, the volume is increased by n times (n = 2, 3, 4,..., An integer) by adding once, twice,. Liquid detergent II can be added.

  In the liquid detergent charging device of Example 2 of the present invention, the state of each valve in each process of charging the first type of liquid detergent I is as shown in Table 2 below.

  In the liquid detergent charging device of Example 2 of the present invention, the state of each valve in each step of charging the second type of liquid detergent II is as shown in Table 3 below.

  Next, a part of the configuration of the liquid detergent charging device (particularly the fixed container 3) of the second embodiment of the present invention is changed, and two types of liquid detergent charging operation can be performed in the cleaning (washing) process. A liquid detergent charging device for an electric cleaning device in Example 3 will be described.

Specifically, the body AII 30112 and the body BII30123, the body AII30112 and the connecting body, the body AII30112 and the link 311, the link 311 and the lid 315 are screwed (for example, press-fitting) Other connection methods such as caulking, welding, welding, etc. may be used.) In the middle of each connecting portion, an O-ring (for example, an elastic member such as silicon rubber) is used to maintain watertightness. Is attached.

A constant volume chamber 3013 is formed in the body 301. The constant volume chamber 3013 is a space (for example, a filling capacity of 20 cc) that can be filled with a liquid detergent (predetermined amount of use) necessary for one washing (or rinsing, finishing) operation. The
Further, a detergent outflow on / off valve is provided inside the body 301 to feed water from the constant volume chamber 3013 to the water case 5, and more specifically, a valve A 302 that opens and closes the water outlet 312 and the constant volume chamber 3013. In addition, a detergent I inflow opening / closing valve is provided to send the liquid detergent I in the liquid detergent tank 2 to the constant volume chamber 3013. Specifically, the liquid supply port BI3016A and the constant volume chamber 3013 are opened and closed. A valve BI is provided, and a detergent II inflow opening / closing valve is provided to send the liquid detergent II of the liquid detergent tank 2 to the constant volume chamber 3013. Specifically, the liquid supply port BII3016B and the constant volume chamber 3013 are provided. A valve BII for opening and closing is provided, and an open / close valve for releasing air from the constant volume chamber 3013 is provided. Specifically, a valve C304 for opening and closing the vacuum port 3017 and the constant volume chamber 3013 is provided. ing.

The valve A302 includes a ball A314 of a valve body placed in a concave space of the link 311 and a valve seat D3112 housed in a space in which the valve seat D3112 of the link 311 can be accommodated.
The valve seat D3112 may be formed of a rubber material or a synthetic resin molded member (for example, polypropylene resin).
The ball A314 was formed of a synthetic resin molded member (for example, polyester resin) having a density lower than that of water so that it floats on water or liquid detergent.
By opening and closing the valve seat D3112 with the ball A314, the constant volume chamber 3013 is opened and closed (communication and closing) via the water outlet 312 and the through hole F3151.

The valve C304 includes the valve seat C30133, and a valve body ball C310 provided between the valve seat C30133 and a base A30113 in which the ball valve body can be accommodated.
The valve seat C30133 may be formed of a rubber material or a synthetic resin molded member (for example, polypropylene resin). The connecting body may be a separate part or the connecting body and an integral part.
A base A30113 that can accommodate the ball valve body is provided on the body AII 30112 so as to face the valve seat C30133.
The ball C310 was formed of a synthetic resin molding member (for example, a polyester resin) having a density lower than that of water so that it floats on water or a liquid detergent. By opening and closing the valve seat C30133 with the ball C310, the vacuum port 3017 and the constant volume chamber 3013 are opened and closed (line communication and line blockage).
The vacuum port 3017 may be in an extreme vacuum (negative pressure) state when the valve C304 is closed by filling with a liquid detergent. For this reason, it is expected that the ball C310 sticks excessively to the valve seat C30133 (in the worst case, bite occurs), and the valve opening operation due to the natural fall accompanying the release to the atmosphere is hindered. In order to prevent such a state, a check valve capable of flowing into the atmosphere in a specified extreme vacuum (negative pressure) state may be provided between the valve seat C30133 and the vacuum port 3017.

The suction generator 4 has a water supply port 401, a water discharge port 402 communicating with the water supply port 401, and a reduced and enlarged cross section in a part of the pipe between the water supply port 401 and the water supply port 402. In detail, it is good also as the shape which applied the nozzle, the orifice, the venturi pipe etc. which are used when measuring the pressure difference p1-p2 by reducing the diameter of the upstream side of the pipe and expanding the diameter of the downstream side. This is a so-called aspirator (inhaler) provided with a contraction port 403 provided with a vacuum generation port 404 communicating with the contraction port 403.
Specifically, when the fluid (water, air) passes through a portion where the flow path called the venturi is restricted, the flow velocity of the fluid increases due to the venturi effect, and the pressure decreases from the fluid pressure (the degree of decrease is understood by Bernoulli's theorem) ) The phenomenon occurs. The venturi effect is a mechanism that generates a lower pressure than the low speed portion by increasing the flow velocity by restricting the flow of fluid. The suction generator 4 applies this venturi effect, and is formed by integral molding with a synthetic resin molding member (for example, polypropylene resin).
In the third embodiment of the present invention, the suction generator 4 is formed as an independent part and connected to the water case 5, but may be a part of the water case 5.

As for the connection between the pipe openings, the pipes and the bond (adhesive / primer) may be directly coupled by a screw fastening method (for example, other connection methods such as press fitting, caulking, welding, welding, etc.). The water outlet A102 of the electromagnetic water supply valve A is connected to the water supply port 313 of the constant vessel 3 by using a binding aid (watertight retaining agent) such as a binding (hose retaining band) or the like, and the electromagnetic water supply valve The water outlet B103 of B is connected to the water supply port 401 of the suction generator 4, and the liquid supply port I3016A of the constant vessel 3 is connected to the detergent I outlet 202 of the liquid detergent tank 2, and the constant vessel 3 is connected to the detergent II outlet 203 of the liquid detergent tank 2, and the vacuum port 3017 of the constant container 3 is connected to the vacuum generation port 404 of the suction generator 4. The water outlet 312 of the container 3 is the water supply of the water case 5. The water outlet 402 of the suction generator 4 is connected to the water supply port B 502 of the water case 5.
In the case of direct coupling, if necessary, an O-ring (for example, an elastic member such as silicon rubber) or the like may be attached in the middle of each connection portion in order to maintain watertightness.

The water case 5 is formed of a synthetic resin molded member (for example, polypropylene resin), but can be separated into one part of a cleaning tank of an electric cleaning device.
In the opening 503 of the water case 5, a drawer case that can store a powder detergent or a consumer-friendly softener can be placed.
By pouring water flowing out from the water supply port B502 into the drawer case, the powder detergent, the softener preferred by the consumer, and the like are dissolved, and the mixed solution is supplied to the cleaning tank of the electric cleaning device.

  An electromagnetic coil I305A having a yoke (a magnetic circuit forming fixed iron core) is provided on the outer periphery of the guide I3018A, and a fixed iron core I306A having a center orifice I3061 coupled to the yoke on the inner periphery of the guide I3018A; A movable iron core I307A (amateur) having a contracted portion I3071A provided with an armature seat I308A of a valve body at an end, and a spring I309A provided between the fixed iron core I306A and the movable iron core I307A are accommodated, and the valve BI The armature seat I308A is opened and closed by moving the valve seat BI30132A apart.

As shown in FIGS. 9 and 11, if the electromagnetic water supply valve A is weakly blocked due to the low water pressure of tap water, a check valve 6 may be provided at the water supply port 313.
The check valve 6 is provided with a base 604 and a valve core 601. The base 604 includes a small ring 6043 surrounded by the ring 6041 and the ring 6041. A fluid through hole 6042 is provided between the small ring 6043 and the ring 6041. A guide for the valve core 601 is in the small ring 6043, a spring 602 is provided outside the guide for the valve core 601, and an O-ring 603 is provided on the valve core 601.

The operation (software) of the liquid detergent charging device according to the third embodiment of the present invention will be described.
When a user uses an electric cleaning device (for example, an electric washing machine) equipped with the liquid detergent charging device according to the third embodiment of the present invention, an amount of liquid detergent I (for example, a laundry detergent) that can be washed several times in advance is used. ) And an amount of liquid detergent II (for example, bleach, softener) that can be rinsed (finished) several times in advance must be placed in the liquid detergent tank 2.
In this state, first, when the electromagnetic water supply valve B is energized, water is passed through the suction generator 4, water passes through the water supply port B 502, and the water is supplied from the open port 503 of the water case 5 to the cleaning tank of the electric cleaning device. Main water supply is performed.
At this time, the state of each valve at the initial stage before adding the liquid detergent is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Opened Constant volume chamber valve BI: Closed Constant volume chamber valve BII: Closed Constant volume chamber valve C: Opened Since there is no water in the constant volume chamber 3013 of the constant container 3, the ball C310 falls to the base A30113 in which the ball valve body can be stored due to its own weight, and the valve C304 is opened.
When negative pressure is generated at the contraction port 403 by water passing through the suction generator 4 and the atmosphere (air) in the constant container 3013 is sucked from the vacuum port 3017 via the valve C304, the negative pressure is generated. The ball A314 is moved to the valve seat D3112 side of the link 311 by the suction negative pressure due to pressure, the valve A302 is closed, the water outlet 312 and the constant volume chamber 3013 are closed, and the constant vessel 3013 is closed. The inside is depressurized and becomes negative pressure (vacuum). However, since the valve BI is in the closed state, the liquid detergent I in the liquid detergent tank 2 does not flow into the constant volume chamber 3013. Similarly, the liquid detergent II in the liquid detergent tank 2 does not flow into the constant volume chamber 3013 because the valve BII is in a closed state.

Next, an operation when the liquid detergent I is charged in the washing process will be described.
When the electromagnetic coil I305A of the constant container 3 is energized, the valve BI is opened, and the liquid detergent I is supplied from the liquid supply port BI3016A to the constant volume due to the negative pressure (vacuum) in the constant volume chamber 3013. The chamber 3013 is filled with suction.
The state of each valve at the time of filling liquid detergent I at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed constant volume chamber valve BI: Opened Constant volume chamber valve BII: Closed constant volume chamber valve C: Opened

When both the electromagnetic coil I305A and the electromagnetic coil II305B are blacked out after a specified time (for example, 20 seconds) and both the valve BI and the valve BII are closed, the suction filling of the liquid detergent I is forcibly terminated. When the constant volume chamber 3013 is filled with the liquid detergent I within the specified time (for example, 20 seconds) due to pressure, the ball C310 closes the valve seat C30133 and the valve C304 is closed, thereby liquid detergent I. Suction is immediately stopped and the current filling operation is completed. (Transfer to standby state after liquid detergent I is full before forced termination of suction filling with liquid detergent I.)
The state of each valve in the standby state after the liquid detergent I is full at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed constant volume chamber valve BI: Opened Constant volume chamber valve BII: Closed constant volume chamber valve C: Closed valve

The state of each valve when the suction of liquid detergent I is forcibly terminated before it is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Closed valve Valve of constant volume chamber C: Opened valve

Here, the operation in the case of performing the charging operation of the liquid detergent II in the rinsing (finishing) step will be described.
When the electromagnetic coil II 305B of the constant container 3 is energized, the valve BII is opened, and the liquid detergent II is supplied from the liquid supply port BII 3016B to the constant volume due to the negative pressure (vacuum) in the constant volume chamber 3013. The chamber 3013 is filled with suction.
The state of each valve at the time of filling liquid detergent II at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Opened valve Valve of constant volume chamber C: Opened valve

When both the electromagnetic coil I305A and the electromagnetic coil II305B are cut off after a specified time (for example, 20 seconds) and both the valve BI and the valve BII are closed, the suction filling of the liquid detergent II is forcibly terminated. When the constant volume chamber 3013 is filled with the liquid detergent II within the specified time (for example, 20 seconds) due to pressure, the ball C310 closes the valve seat C30133 and the valve C304 is closed, thereby liquid detergent II. Suction is immediately stopped and the current filling operation is completed. (Transfer to standby state after liquid detergent II is full before forced termination of liquid detergent II suction filling.)
The status of each valve in the standby state after the liquid detergent II is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened Constant volume chamber valve A: Closed Constant volume chamber valve BI: Closed Constant volume chamber valve BII: Opened Constant volume chamber valve C: Closed valve

The state of each valve when the suction filling of Liquid Detergent II is forcibly terminated before it is full is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Opened valve of constant volume chamber A: Closed valve Valve of constant volume chamber BI: Closed Valve of constant volume chamber BII: Closed valve Valve of constant volume chamber C: Opened valve

Then, when the electromagnetic water supply valve B is blacked out (not energized) or energized and the electromagnetic water supply valve A is energized, water passes from the water supply port 313 to the through hole L3111 and passes through the center orifice I3061 of the fixed iron core I306A. The constant volume chamber passes through the inner peripheral portion of the guide I3018A while cleaning the pipe of the constant volume chamber 3013, passes through the center orifice II3062 of the fixed iron core II306B, passes through the inner peripheral portion of the guide II3018B, and passes through the inner periphery of the guide II3018B. Water is passed through the constant volume chamber 3013 (water injection) through the pipe 3013 while being washed, and the ball C310 is caused by the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber 3013. While maintaining the closing of the valve seat C30133 (forced closing when the valve is opened), the liquid mixture of the suction-filled liquid detergent and water flows from the outlet 3014 to the through hole F3151. As a result, the mixed solution of water and liquid detergent is supplied from the opening 503 of the water case 5 to the cleaning tank of the electric cleaning device through the valve A302, out of the water outlet 312 and through the water supply port A501. .
Further, when water from the electromagnetic water supply valve A flows into the constant volume chamber 3013, the liquid mixture in the constant volume chamber 3013 is diluted to a state close to water, the viscosity decreases, and low-viscosity diluted water (finally tap water). Since the valve A302 always passes through the cleaning, it is possible to prevent the valve from being solidified by the liquid detergent.
The state of each valve in the water injection state at this time is as follows.
Electromagnetic water supply valve A: Open valve Electromagnetic water supply valve B: Valve closed or open Constant volume chamber valve A: Open valve Constant volume valve BI: Closed Constant volume chamber valve BII: Closed constant volume chamber valve C : Valve closed

Finally, when both the electromagnetic water supply valve B and the electromagnetic water supply valve A are powered off (no power supply), the water that has been passed through the suction generator 4 and the constant vessel 3 stops. When the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber 3013 disappears, the atmosphere enters the water outlet 402, the vacuum generation port 404, and the vacuum port 3017 in order from the water supply port B502. When the inside of the pipe is opened to the atmosphere, the ball C310 that has blocked the valve seat C30133 naturally falls and leaves the valve seat C30133, and the atmosphere enters the constant volume chamber 3013, and the constant volume chamber 3013 is released. The low-viscosity diluted water remaining in the volume chamber 3013 is drained from the water outlet 312 and the inside of the constant volume chamber 3013 becomes empty (empty).
Then, the next filling operation can be performed.
The state of each valve during drainage of the constant volume chamber 3013 at this time is as follows.
Electromagnetic water supply valve A: Closed valve Electromagnetic water supply valve B: Closed valve Constant volume chamber valve A: Open constant volume chamber valve BI: Closed Constant volume chamber valve BII: Closed constant volume chamber valve C: Opened valve Thus, two types of liquid detergents (liquid detergent I and liquid detergent II) can be charged by selecting the operation of either the electromagnetic coil I305A or the electromagnetic coil II305B of the fixed container 3.
In the liquid detergent charging device according to the third embodiment of the present invention, the switching mechanism of the two types of liquid detergent is a direct acting valve type three-way valve. The drive system of the valve is not particularly limited to an electromagnetic type, an electric type, a manual type, or the like.
In addition, for example, two or more independent constant containers equipped with one direct acting valve type electromagnetic two-way valve may be combined, and a plurality of valves B can be mounted on the constant container 3. It is good also as a fixed container carrying the switching mechanism of three or more types of liquid detergents.

Although the expression that the inside of the constant volume chamber 3013 is empty (empty) due to drainage is taken, actually, depending on the position of the water supply port A501 of the water case 5 and the position of the water outlet 312 of the constant volume chamber 3013. In some cases, the water supply port A501 and the water outlet 312 are not completely emptied because of the pipe connection.
As shown in FIG. 8a, when the water supply port A501 is at a horizontal position with the water outlet 312 or lower than the position, the water supply port A501 is often almost empty.
If the water supply port A501 is higher than the water outlet 312 as shown in FIG. 8b, it may not be completely empty. Reference numeral 30135 represents the actual filling capacity or the amount of water that can be drained.

  Liquid detergent (liquid detergent I and liquid detergent II) corresponding to the volume of the constant volume chamber 3013 (for example, 20 cc in the volume of the substantial filling capacity 30135) can be charged in one operation. In this case, n times the volume (n = 2, 3, 4,..., Integer) of the liquid detergent I can be added by an additional operation once, twice,. Similarly, when a large amount of liquid detergent II is to be added, the volume is increased by n times (n = 2, 3, 4,..., An integer) by adding once, twice,. Liquid detergent II can be added.

  In the liquid detergent charging apparatus of Example 3 of the present invention, the state of each valve in each process of charging the first type of liquid detergent I is also as shown in Table 2 above. Similarly, the state of each valve in each process of introducing the second type of Liquid Detergent II is as shown in Table 3 above.

  As mentioned above, although various combinations etc. were described about the preferred embodiment of this invention, this invention is not limited to embodiment mentioned above, Many combinations and modification | change are within the range which does not deviate from the mind of invention. Of course, etc. can be given.

For example, the fixed container 3 may not be a part separated from the water case 5 but may be integrally formed with the water case 5.
For example, the suction generator 4 may be provided on the upper part of the fixed container 3 and connected to the water case 5 without being connected to the upper part of the water case 5.
For example, the water case 5 may serve as the inner lid of the washing machine, or may be incorporated as a part of the upper operation panel of the washing machine.
The configuration and operation may be modified according to the demands and specifications of the manufacturer of the electric cleaning device.

If it is an electric washing device that involves the introduction of a liquid detergent, it will wash not only washing machines that wash clothing, but also water grains 5 etc. according to the shape and specifications to wash grains and vegetables such as potatoes. Liquids such as food washing machines, dishwashers that wash dishes, toilet bowl local washing equipment that is placed on a Western-style toilet and sprays fragrance while washing the toilet or other parts of the body where filth adheres It can also be applied to a detergent charging device.
The present invention can be applied not only to the addition of liquid detergents but also to the addition of other liquid agents (for example, bleaching agents, softening agents, sterilizing liquids).
Then, the supplied liquid detergent (particularly the fragrance) may be undiluted or diluted, and for example, atomized with an ultrasonic vibrator and sprayed.

II (306B), a movable core II (307B) having a contraction portion II (3071B) provided with an armature seat II (308B) at the end, a fixed core II (306B), and a movable core II ( 307B) is housed, and the valve BII is opened and closed by moving the armature seat II (308B) apart from the valve seat BII (30132B).
In operation, first, when the electromagnetic water supply valve B is energized, water passes through the suction generator (4), passes through the water supply port B (502), and from the open port (503) of the water case (5). The main water supply water is supplied to the washing tank of the electric washing device, a negative pressure is generated at the contraction port (403), and the negative pressure is supplied from the vacuum port (3017) to the constant volume chamber (3013). When transmitted, the ball A (314) is moved to the valve seat D (3112) side of the link (311) by suction negative pressure, and the water outlet (312) and the constant volume chamber (3013) are blocked. When the inside of the constant volume chamber (3013) is becoming a negative pressure, when either the electromagnetic coil I (305A) or the electromagnetic coil II (305B) of the constant container (3) is energized, the valve BI And the valve BII are opened, the liquid supply port BI (3016A) and the liquid supply port BII (301 B) Liquid detergent is sucked and filled into the constant volume chamber (3013) from either one of the above, and after a specified time, both the electromagnetic coil I (305A) and the electromagnetic coil II (305B) are blacked out, and the valve BI and the valve When both of the BIIs are closed, the suction filling of the liquid detergent is forcibly terminated, but when the constant volume chamber (3013) is filled with the liquid detergent within the specified time due to the negative pressure, the ball C (310) The valve seat C (30133) is closed, the valve C (304) is closed, the liquid detergent suction is immediately stopped, and the current filling operation is completed (standby state after full).
When the electromagnetic water supply valve B is blacked out (or maintained energized) and the electromagnetic water supply valve A is energized, water passes from the water supply port (313) to the through hole L (3111), and the fixed iron core I (306A ) Through the center orifice I (3061), through the inner periphery of the guide I (3018A), and through the conduit of the constant volume chamber (3013), and through the center of the fixed core II (306B). Water passes through the orifice II (3062), the inner periphery of the guide II (3018B) and the pipe of the constant volume chamber (3013) while being washed, and water is passed through the constant volume chamber (3013). The liquid detergent filled with suction while maintaining the closing of the valve seat C (30133) by the ball C (310) by the water flow pressure from the electromagnetic water supply valve A applied to the constant volume chamber (3013) A mixture of water is discharged from the outlet (3014). Water and liquid flow out of the water outlet (312) through the through hole F (3151), through the water supply port A (501), and from the opening (503) of the water case (5) to the washing tank of the electric cleaning device. When the liquid mixture with the detergent is supplied and water from the electromagnetic water supply valve A flows into the constant volume chamber (3013), the mixed liquid in the constant volume chamber (3013) is close to water. Diluted to a low viscosity viscosity water.
Finally, when both the electromagnetic water supply valve B and the electromagnetic water supply valve A are cut off, the water passed through the suction generator (4) and the constant vessel (3) is stopped, and the constant volume When the water flow pressure from the electromagnetic water supply valve A applied to the chamber (3013) disappears, the air flows in order from the water supply port B (502) to the water discharge port (402), the vacuum generation port (404), the vacuum When the air enters the mouth (3017) and is released to the atmosphere, the ball C (310) that has blocked the valve seat C (30133) is separated from the valve seat C (30133), and the atmosphere is supplied to the constant volume chamber (3013). The low-viscosity dilution water remaining in the constant volume chamber (3013) is drained from the outlet (312) and the constant volume chamber (3013) is emptied, so that the next filling operation is performed. Will be able to
2. A liquid detergent charging device characterized in that two types of liquid detergent can be charged by selecting an operation of either the electromagnetic coil I (305A) or the electromagnetic coil II (305B) of the fixed container (3).
