[0002]

2. Description of the Related Art A beverage dispensing apparatus is known as an apparatus for diluting a concentrated stock solution such as juice with cooling water for drinking. If the basic structure of the beverage dispensing apparatus is described as an example, a pump is provided inside a refrigerator that stores a container storing the concentrated undiluted solution, and the pump is driven in a state where the concentrated undiluted solution container is connected to a suction port of the pump. Thereby, a required amount of the undiluted solution is supplied to the nozzle connected to the discharge port of the pump. Further, in a liquid tank in which an evaporator derived from the refrigeration mechanism is disposed, a cooling liquid for immersing the evaporator is stored, and a refrigerant is circulated to the evaporator to cool the evaporator. A part of the cooling liquid is frozen around the evaporator. Further, in this liquid tank, a beverage cooling pipe is disposed so as to be immersed in a cooling liquid while being separated from the evaporator by a predetermined distance, and one end of the beverage cooling pipe is connected to and connected to an external water supply system, The other end is connected to the nozzle via an on-off valve. That is, the tap water supplied to the beverage cooling pipe from the external water supply system is cooled by heat exchange with the cooling liquid when passing through the portion provided in the liquid tank. Then, a required amount of the stock solution in the concentrated stock solution container is supplied to the nozzle portion via a pump, and cooling water is supplied to the nozzle portion via a beverage cooling pipe. It is poured out from the department and served for drinking.

[0003] The concentrated stock solution container is in an inverted state in which a discharge port provided in the container is directed downward, and the discharge port is detachably connected to a suction port of the pump. It is constituted so that it can be removed from. In addition, a valve element that opens when the discharge port is connected to the suction port of the pump is disposed at the discharge port of the container, and is set so that the concentrated stock solution container communicates with the suction port of the pump. Thus, when the impeller-type impeller provided in the pump chamber of the pump is rotated, the concentrated stock solution sucked from the suction port can be discharged from the discharge port to the nozzle portion through the pump chamber.

Here, when the concentrated undiluted solution container and the pump are connected, the concentrated undiluted solution in the container always flows into the pump side. In order to prevent leakage from the discharge port, the impeller provided in the pump chamber is made of rubber, and the impeller is always in contact with the inner wall of the pump chamber. Accordingly, the portion communicating with the suction port and the portion communicating with the discharge port in the pump chamber are blocked by the impeller, and leakage of the concentrated undiluted solution from the discharge port is prevented.

[0005]

In the above-described structure for preventing the concentrated undiluted solution from leaking, when the impeller is rotated, the impeller moves while always in contact with the inner wall of the pump. As a result, there is a problem that the sealing performance is reduced. Also, the pump chamber is not perfectly round due to the location of the suction port and discharge port, etc., and the frictional resistance between each impeller and the pump chamber wall becomes uneven, which causes the impeller to twist and seal. And the concentrated stock solution leaks from the discharge port.

Further, in the structure in which the discharge port of the concentrated undiluted liquid container is directly connected to the suction port of the pump, it is necessary to remove the container from the pump for maintenance such as disassembly and cleaning of the pump, which makes maintenance difficult. Is done.
In addition, when the concentrated stock solution container is connected to the pump that has been disassembled and cleaned, the air remaining in the pump chamber and the suction port enters the container and mixes with the concentrated stock solution, resulting in unsanitary problems. is there.

[0007]

SUMMARY OF THE INVENTION In view of the above-mentioned problems inherent in the prior art, the present invention has been proposed to solve the problem suitably, and it is intended to surely prevent the leakage of the liquid and to prevent the liquid from being leaked. An object of the present invention is to provide a connection structure for a liquid container that can be kept hygienic at all times.

[0018]

Next, the operation of the connection structure of the concentrated stock solution container in the beverage dispensing apparatus according to the embodiment will be described below. As shown in FIG. 4, when a discharge port 43 of the concentrated stock solution container 21 is connected to a joint 42 connected to a suction port 38b of the pump 38, a check valve 46 disposed at the discharge port 43 is operated to release the discharge. The outlet 43 is opened. At this time, since the tapered through-hole 62 a of the check valve 60 fitted in the joint 42 is closed by the valve body 68 provided therein, the concentrated undiluted solution flowing from the concentrated undiluted solution container 21 into the joint 42 is checked by the check valve 60. Suction port 3 of pump 38
8b is blocked.

In this state, if the impeller 41 of the pump 38 is rotated in a predetermined direction by the geared motor 40, a required suction force is generated in the pump chamber 38a and the suction port 38b. As a result, the valve element 68 of the check valve 60 moves in a direction to open the tapered through hole 62a against the elasticity of the compression spring 72 as shown in FIG. As a result, the concentrated stock solution stored in the concentrated stock solution container 21 is supplied to the joint 42, the check valve 60, and the suction port 38.
The fluid is sucked into the pump chamber 38a through the valve b. Next, the undiluted solution is supplied from the pump chamber 38a to the discharge nozzle 24 via the discharge port 38c and the joint 55. The cooling water cooled by the cooling device 28 is supplied to the discharge nozzle 24 through the hose 57 and the joint 55 by opening the water valve 32, where the concentrated stock solution is diluted and discharged to the outside. It is.

When the geared motor 40 is stopped by supplying a required amount of concentrated undiluted solution from the concentrated undiluted solution container 21 to the discharge nozzle 24, the valve 6 of the check valve 60 is stopped.
8 moves upward by the elastic force of the compression spring 72, and closes the tapered through hole 62a by the tapered portion 68b. Therefore, new inflow of the concentrated stock solution stored in the concentrated stock solution container 21 into the suction port 38b of the pump 38 is prevented. When the impeller 41 is stopped, the suction port 38b and the discharge port 38c are spatially shut off in the pump chamber 38a by the impeller 41, so that the impeller 41 remains in the suction port 38b and a part of the pump chamber 38a. Leakage of the concentrated undiluted solution from the discharge port 38c is prevented. Even when the impeller 41 impairs the sealing performance, the concentrated stock solution container 21 and the suction port 38b of the pump 38 are spatially shut off by the check valve 60 provided in the joint 42. , Suction port 3
Although the concentrated raw material remaining in 8b and a part of the pump chamber 38a leaks, the outflow of the undiluted solution from the concentrated undiluted solution container 21 can be surely prevented.

Since the inside of the pump 38 becomes dirty with time, if it is left as it is, it promotes the growth of various bacteria and becomes unsanitary. Therefore, it is necessary to periodically clean the pump.
In the case of the embodiment, the check valve 60 of the joint 42 is used.
Since the concentrated stock solution container 21 and the pump 38 are spatially isolated from each other, the pump 38 can be removed from the apparatus 10 and disassembled and cleaned while the container 21 is connected to the joint 42. In addition, the pump 38 after the disassembly and cleaning has been completed.
Is mounted on the device 10, the pump chamber 3 of the pump 38
It is possible to prevent the air remaining in the concentrated liquid 8a and the suction port 38b from entering the concentrated raw liquid container 21 by the check valve 60, so that the concentrated raw liquid in the container 21 can be always kept hygienic.

[0022]

As described above, according to the connection structure of the liquid container in the liquid dispensing apparatus according to the present invention, it is possible to disassemble and clean only the pump from the apparatus main body while the liquid container is connected to the joint. And maintenance work can be easily performed. In addition, since the liquid container is held in a non-communication state with the outside by the closing means inserted into the joint, when the pump that has been completely disassembled and cleaned is connected, the air remaining inside the pump remains in the liquid container. It can prevent entry and keep the liquid always sanitary.
