By the way, the above-mentioned method of supplying water with a cassette-type water storage tank differs from the method of supplying water by connecting directly to the water supply because the drinking water stored in the cassette-type water storage tank remains stored for a long time. , water quality control is strictly regulated under the Food Sanitation Law, and for this reason, as shown in the figure, the water supply pipe is usually equipped with a sterilizing filter 5 to sterilize drinking water before it is sold. has been adopted. The sterilizing filter 5 is made of, for example, a filter cloth bound with activated carbon powder that removes limescale contained in water and a chemical powder having a sterilizing and disinfecting action.

くなる。 However, in such a water supply circuit that supplies water by interposing a sterilizing filter in the water supply pipe, the following problems occur. In other words, during the initial water supply immediately after setting a new sterilizing filter, the unstable powders that have adhered to the filter cloth of the sterilizing filter are separated from the filter cloth by the water supply pressure of the water pump, and the drinking water is released. This may cause problems such as contamination. Note that the outflow of this powder will no longer occur and will become stable once water is passed through it to a certain extent. Furthermore, when sanitizing the beverage circuit, particularly the cold beverage line, on a regular basis, it is difficult to inject a sterilizing chemical into the beverage line with the conventional circuit configuration. In other words, when the sanitation liquid, which is a medicinal solution, is injected from the starting end of the water supply pipe 2 shown in FIG. As a result, the chemical components in the sanitation liquid are adsorbed by the activated carbon of the sterilization filter, reducing the sanitation effect on the beverage line. For this purpose, the conventional method has been to remove the sterilizing filter and inject sanitation liquid from the end of the pipe, but this method is time-consuming and extremely difficult to service.

It is an object of the present invention to provide a water supply circuit that allows direct injection of a sanitation chemical solution into external drainage and a drinking line.

とになる。 Next, the structure and usage of the three-way switching valve 25 described above will be explained with reference to FIGS. 2 to 4. The three-way switching valve 26 has ports a, b and a branch port c that opens outside the system. It is configured to selectively communicate between two ports, and ports a and b are connected to the sterilizing filter 5 side and the beverage line side, respectively, as shown in the figure. During normal beverage sales, the three-way switching valve 26 is set at a position where ports a and b are electrically connected, as shown in FIG. Water is supplied to a beverage line 7 or a cold beverage line 8. In this state, branch port c is closed. On the other hand, when replacing the sterilizing filter 5 with a new one, first switch the three-way switching valve 26 to the port a-c conduction position as shown in FIG. I do. Therefore, fine powder such as activated carbon that has separated from the sterilizing filter 5 and flowed out during this initial water flow process is drained to the drainage bucket 30 outside the system through the branch port c of the three-way switching valve 26 together with the discharged water. Thereby, it is possible to prevent defective drinking water from flowing into the drinking lines 7 and 8 and mixing with the drinks. After this initial water flow has been carried out for a suitable period of time, the three-way switching valve 26 is again switched to the position shown in FIG. 2 and the sales operation begins. In addition, when regularly sanitizing the beverage line, especially the cold beverage line 8 that requires sanitation (sanitation can be omitted for hot beverage lines as they are sterilized by heating with hot water), the three-way switching valve 26 is switched to the position shown in Fig. 4 to establish continuity between ports b and c, and in this state, connect the chemical liquid tank 31 to the branch port c, and connect it to the drinking water line 24 on the downstream cold drinking line 8 side through the three-way switching valve. Inject sanitation fluid.
Therefore, the sanitation liquid can be directly injected into the beverage line without passing through the sterilization filter 5, and its sterilization and disinfection effects can be fully exhibited.
なおこの考案は第１図の実施例に限らず、第５

はもちろんである。 Note that this invention is not limited to the embodiment shown in Fig. 1;
It goes without saying that the present invention can be implemented in a similar manner not only in the beverage circuit shown in the figure, but also in a machine exclusively for cold beverages.

As described above, according to this invention, a three-way switching valve having a branch port opened to the outside of the system is connected to the outlet side of the sterilizing filter, and during normal sales, the branch port of the three-way switching valve is closed and the line is connected to the beverage line. During the initial water flow after replacing the sterilizing filter,
And when sanitizing the beverage line, the branch port is opened to drain the defective water flowing through the sterilizing filter, and to inject the sanitation liquid into the beverage line. This makes it possible to easily drain water and inject sanitation liquid when sanitizing the beverage line using the walk-through switching valve, thus improving serviceability in terms of maintenance and management of the vending machine.
