  The present invention has been invented in view of the above-described conventional problems, and the object of the present invention is to provide a foam detergent discharge device capable of producing a foam detergent having a high cleaning effect and preventing leakage of the detergent. It is to provide.

  In order to solve the above-mentioned problems, the invention according to claim 1 is characterized by the following configuration.

  A detergent supply path 4 to which the detergent A from the detergent tank 2 is supplied to the main body 3 to which the detergent tank 2 is mounted, and an ejector for generating foam detergent B by mixing air into the detergent A in the detergent supply path 4 It is a foam detergent discharge device provided with a part 6 and a pump 8 that pressurizes the foam detergent B and sends it to the washing nozzle 7 side. A detergent outlet 9 is provided at the bottom of the detergent tank 2 in which the liquid detergent A is stored. A tank air layer 11 for collecting air taken into the detergent tank 2 from the outside and a tank air outlet 10 for taking out air from the tank air layer 11 are provided at the upper part of the detergent tank 2. On the side of the main body 3 to which the detergent tank 2 is detachably attached, a main body detergent receiving port 12 that communicates with the detergent supply path 4 and a main body air receiving port 13 that communicates with the air supply path 5 of the ejector unit 6 are provided. When the detergent tank 2 is attached to the main body 3, the detergent outlet 9 and the main body detergent receiving port 12 are connected, and at the same time, the tank air outlet 10 and the main body air receiving port 13 are connected.

  By adopting such a configuration, it is possible to supply detergent from the detergent outlet 9 into the detergent supply path 4 and supply air from the tank air outlet 10 into the air supply path 5 only by the mounting operation of the detergent tank 2. Thus, the foam detergent B having a high cleaning effect can be generated in the ejector portion 6 of the main body 3. Even if the detergent A flows backward from the ejector section 6 into the air supply path 5 when the cleaning nozzle 7 is closed, the detergent A circulates from the main body air receiving port 13 into the detergent tank 2 through the tank air outlet 10. Therefore, the detergent A that has flowed back does not leak from the main body air receiving port 13.

  In addition, the tank air layer 11 and the tank air outlet 10 are connected via an air pipe 14, and the air pipe 14 is lower than the top end level L of the tank air layer 11 and from the tank air outlet 10. In this case, when the detergent A is excessively put into the detergent tank 2, an excess of the detergent A is connected to the tank air layer 11 and the tank air outlet 10. Since it overflows from the tank air outlet 10, the inside of the detergent tank 2 does not become full. That is, the tank air outlet 10 becomes a full water indication line, and a tank air layer 11 having a constant capacity can be secured in the upper part of the detergent tank 2, so that air can be continuously supplied from the tank air layer 11 to the main body air receiving port 13. .

  In addition, a sub tank 15 for storing a certain amount of detergent A is provided in the detergent supply path 4 between the main body detergent receiving port 12 and the ejector unit 6, and an air supply path between the main body air receiving port 13 and the ejector unit 6. It is preferable that the branch pipe 16 branched from the inside of the sub tank 15 communicates with the inside of the sub tank 15. In this case, the sub tank 15 puts the detergent A into the detergent tank 2 in addition to the role of compensating for the lack of detergent in the detergent tank 2. If excessive, the excess detergent A overflowing from the tank air outlet 10 is supplied from the main body air receiving port 13 to the inside of the sub tank 15 through the branch pipe 16 of the air supply path 5. It serves to prevent leakage due to.

  The present invention makes it possible to produce a foam detergent having a high cleaning effect in the ejector portion of the main body only by attaching the detergent tank to the main body, and even when the detergent flows back into the air supply path when the cleaning nozzle is closed, etc. It is possible to reliably prevent leakage.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 is a schematic configuration diagram of the entire foam detergent ejection device 1 according to the present embodiment, FIG. 2 is an explanatory diagram of a state where the detergent tank 2 is removed from the main body 3, and FIG. 3 is an explanatory diagram of the internal structure of the ejector unit 6. FIG.

  A detergent outlet 9 with a check valve is provided at the bottom of the detergent tank 2 in which the liquid detergent A is stored. When the detergent outlet 9 with a check valve is connected to the main body detergent receiving port 12, the check valve opens and the detergent can be supplied from the detergent outlet 9, while the detergent tank 2 is removed from the main body 3. Has a structure in which the check valve is closed and the detergent A does not leak from the detergent outlet 9. In addition, as liquid detergent A, what was obtained by diluting the detergent stock solution containing surfactant 5 to 10 times with water is used, for example. Of course, the type of detergent A does not matter.

  A tank air layer 11 for collecting air taken into the detergent tank 2 from the outside is provided in the upper part of the detergent tank 2, and the air in the tank air layer 11 is discharged to one side of the upper part of the detergent tank 2. A tank air outlet 10 is opened downward.

  The tank air layer 11 and the tank air outlet 10 are connected via an air pipe 14. The air pipe 14 is formed in an inverted U shape when viewed from the side, and is positioned lower than the top end level L of the top surface portion 2a of the tank air layer 11 and higher than the tank air outlet 10. When the inside of the detergent tank 2 becomes full due to excessive filling, the excess detergent A overflows from the tank air outlet 10 through the air pipe 14. That is, in addition to the role of guiding the air of the tank air layer 11 to the tank air outlet 10, the air duct 14 has a role of always ensuring a fixed volume of the tank air layer 11 in the upper part of the detergent tank 2, as will be described later. In addition, it serves to prevent the detergent A from being excessively added.

  The top surface 2 a of the detergent tank 2 is provided with an air intake port 19 with a check valve for taking in air from outside into the tank air layer 11. This air intake port 19 with a check valve prevents the leakage of the detergent A from the air intake port 19, and when the air pressure in the tank air layer 11 decreases due to the decrease in the detergent A, the check valve opens to open the air intake port. The external air from 19 can be taken in. Further, one half of the top surface portion 2a of the detergent tank 2 is a stepped portion 2b, and a detergent inlet 20 that is opened and closed by a cap 18 is provided in the stepped portion 2b, and dust and the like are collected below the portion. A strainer 21 is disposed.

  On the other hand, the main body 3 to which the detergent tank 2 is detachably attached is portable and includes a detergent supply path 4, an ejector section 6, a pump 8, and the like. In FIG. 1, 22 is an operation unit, 23 is a control unit, 24 is an AC adapter (switching power supply), 25 is a plug, and 26a, 26b, and 26c are electrical wirings.

  As shown in FIG. 2, the main body 3 is provided with a mounting recess 27 in which the detergent tank 2 is mounted. The mounting recess 27 is open upward in this example, the main body detergent receiving port 12 is opened upward on the bottom surface of the mounting recess 27, and the main body air receiving port 13 is opened upward on the side surface of the mounting recess 27. Yes. The main body detergent receiving port 12 constitutes the upstream end of the detergent supply path 4, and the main body air receiving port 13 constitutes the upstream end of the air supply path 5 of the ejector unit 6. The main body air receiving port 13 is provided with a check valve (not shown). When the detergent tank 2 is mounted on the main body 3 and the tank air outlet 10 is connected to the main body air receiving port 13 as will be described later. When the check valve is pushed open, air can be supplied from the tank air outlet 10. On the other hand, when the detergent tank 2 is removed from the main body 3, the check valve is closed so that the portable main body 3 is Even when it falls, the detergent A does not leak from the main body air receiving port 13. The method for attaching and detaching the detergent tank 2 is not limited to the vertical direction, and may be from the horizontal direction or the oblique direction.

  As shown in FIG. 1, the detergent supply path 4 inside the main body 3 hangs downward from the main body detergent receiving port 12, and a sub tank 15 and an ejector section 6 which will be described later are provided in the middle of the detergent supply path 4. The downstream end of the detergent supply path 4 is connected to the suction side of the pump 8.

  The air supply path 5 inside the main body 3 hangs downward from the main body air receiving port 13, and a branch pipe 16 connected to a sub tank 15, which will be described later, branches in the middle of the air supply path 5. The downstream end 5 a of the path 5 communicates with the ejector portion 6.

  Here, when the detergent tank 2 is mounted in the mounting recess 27 of the main body 3, the detergent outlet 9 and the main body detergent receiving port 12 are connected, and at the same time, the tank air outlet 10 and the main body air receiving port 13 are connected. It has become. Accordingly, the detergent A from the detergent outlet 9 is supplied into the detergent supply path 4 via the main body detergent receiving port 12, and the air from the tank air outlet 10 is supplied from the main body air receiving port 13 to the air supply path. The foam detergent B is produced by the air being mixed into the detergent A that is sucked into the ejector section 6 through the interior 5 and passes through the ejector section 6.

  That is, as shown in FIG. 3, the ejector portion 6 is formed with a tapered cylindrical throttle portion 30 whose diameter decreases toward the downstream side (the pump 8 side). An annular space 31 is formed between the inner peripheral surface of the ejector portion 6. A downstream end 5 a of the air supply path 5 is connected to the lower surface portion of the ejector portion 6. When the pump 8 is driven, a negative pressure is generated in the vicinity of the tip of the throttle portion 30 due to the flow of the detergent A in the ejector portion 6, and the air in the tank air layer 11 is supplied from the tank air outlet 10 to the air supply path 5 by this negative pressure. When the tank air layer 11 becomes negative pressure at this time, external air is taken in from the air intake port 19 of the detergent tank 2 so that the tank air layer 11 is always replenished with air. The Thereby, air C is continuously mixed in the detergent A flowing in the ejector section 6 to generate the foam detergent B. The foam detergent B is pressurized by the pump 8 and connected to the discharge side of the pump 8. It is sent from the discharge hose 32 to the cleaning nozzle 7. The foam detergent B discharged from the cleaning nozzle 7 is preferably in the form of microbubbles having a bubble diameter of 10 to 100 μm and a void ratio of 50 to 80%, for example.

  Further, in this example, a sub tank 15 for temporarily storing the detergent A from the detergent tank 2 is provided in the middle of the detergent supply path 4 between the main body detergent receiving port 12 and the ejector section 6. By storing a certain amount of detergent A in the sub-tank 15, for example, even when the detergent tank 2 is removed for replenishing the detergent, the detergent supply from the sub-tank 15 to the detergent supply path 4 can be performed without stopping the supply of the detergent A. You can continue to do it. Further, a branch pipe 16 branched from the air supply path 5 between the main body air receiving port 13 and the ejector unit 6 is connected to the sub tank 15, so that the sub tank 15 can prevent the detergent in the detergent tank 2 from being insufficient. It serves to prevent harmful effects caused by the excessive addition of the detergent A.

  Thus, according to the above configuration, when the detergent tank 2 is mounted on the main body 3, the connection between the detergent outlet 9 and the main body detergent receiving port 12 and the connection between the tank air outlet 10 and the main body air receiving port 13 are simultaneously performed. Therefore, the detergent supply from the detergent outlet 9 into the detergent supply path 4 and the air supply from the tank air outlet 10 into the air supply path 5 can be performed only by the mounting operation of the detergent tank 2, thereby the ejector of the main body 3. In part 6, foam detergent B having a high cleaning effect can be generated. In addition, since the main body air receiving port 13 is connected to the tank air outlet 10, even if the detergent A flows backward from the air supply path 5 when the cleaning nozzle 7 is closed, the detergent A that has flowed back from the main body air receiving port 13 Since it circulates in the detergent tank 2 through the air pipe 14 at the outlet 10, it is possible to prevent the detergent A that has flowed back from leaking outside from the main body air receiving port 13, and to insulate the pump 8 and the control unit 23 inside the main body 3 There is an advantage that unsafe phenomena such as deterioration can be eliminated.

  Further, when the detergent A is put in the detergent tank 2 excessively, the excess detergent A overflows from the tank air outlet 10 through the air pipe 14, so that the detergent tank 2 is not filled with water. In other words, the tank air outlet 10 becomes a full water indicator line, and a certain volume of the tank air layer 11 can be surely secured in the upper part of the detergent tank 2, so that air supply from the tank air layer 11 to the main body air receiving port 13 can be continuously performed. become. Further, if the detergent A is excessively added when the detergent A is supplied into the detergent tank 2 with the detergent tank 2 attached to the main body 3, the excess detergent A overflowing from the tank air outlet 10 is removed from the main body air. Since it is supplied into the sub tank 15 through the branch line 16 of the air supply path 5 from the receiving port 13, the overflowing detergent A will not leak. In addition, since the sub tank 15 communicates with the main body air inlet 13 via the branch pipe 16, a constant capacity air layer 17 is secured also in the upper part of the sub tank 15. The detergent A overflowing from 16 can be received in the sub tank 15.

  In this example, since the check valve is also provided in the main body air receiving port 13, when the detergent tank 2 is removed, the check valve can be closed to prevent the reverse flow of the detergent A, and the portable main body 3 is temporarily assumed. There is also an advantage that the detergent A can be prevented from overflowing from the main body air receiving port 13 to the outside even if it falls.

  In the above-described embodiment, the main body 3 is portable and can be carried. However, the main body 3 is not limited to the portable type, and may be a stationary type that is fixed at one place.

It is a schematic side view explaining the foam detergent discharge device of one embodiment of the present invention. It is a schematic side view of the state which removed the same detergent tank from the main body. It is sectional drawing explaining the ejector part same as the above.
