Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispenser for providing a drinking water in which a stock solution for drinking water and a diluting water for diluting the same are poured out and mixed.

[0002]

2. Description of the Related Art Conventionally, for providing juice or coffee, a concentrated undiluted solution (hereinafter referred to as syrup) is poured into a container together with dilution water separately from a vending machine for canned juice. BACKGROUND ART Dispensers, which are drinking water supply devices that provide prepared drinking water, are widely used. Under such circumstances, a dispenser employing a multi-valve has been adopted from the viewpoint of reducing the space and simplifying the structure of the piping. Here, FIG. 4 shows a conceptual diagram of the multi-valve. Such a multi-valve includes syrup valves 101 to 101 in which syrup tanks for various drinking water are provided in the valve body 100.
Each dilution water tank that is piped to 104 and is poured as cold water or carbonated water to be discharged as dilution water is piped to a cold water valve 105 or a carbonated water valve 106.

[0003] Syrup valves 101 to 104 provided in the valve body 100 are provided in branch holes branched from one syrup supply hole formed in the center of the valve body 100, and various syrups are all provided in the syrup valve 101.
When ~ 104 are opened, they flow through the syrup supply hole and are discharged into the container 107. As a result, syrup remains in the syrup supply hole, and then the carbonated water is poured into the tributary hole located upstream of the syrup supply hole in consideration of the influence of the selected different syrup on drinking water and hygiene. Cleaning valve 108 is provided. The cleaning valve 108 is connected to a carbonated water tank similar to the carbonated water valve 106.

[0004] Therefore, in a dispenser having such a configuration, a switch for indicating desired drinking water is turned on by a purchaser.
Then, a predetermined one of the syrup valves 101 to 104 is opened, and one of the cold water valve 105 and the carbonated water valve 106 is opened according to the carbonated drinking water or the non-carbonated drinking water. Therefore, syrup and cold water or carbonated water
7 are separately poured out and mixed in the container 107 to make drinking water. And immediately after that, the cleaning valve 1
08 is opened, and a small amount of carbonated water is supplied to the upstream side of the syrup supply hole of the valve body 100. The carbonated water is washed away in the syrup supply hole of the syrup just discharged, and is discharged together with the syrup that has been rinsed into the container 107 in which the drinking water is made.

[0005]

However, in the conventional dispenser, carbonated water was used as washing water in any syrup to remove syrup remaining in the syrup supply hole, so that non-carbonated drinking water was produced. Later, carbonated water was mixed in and sometimes affected the taste. On the other hand, although carbonated water has an excellent bacteriostatic effect in the flow path, it is conceivable to use cold water used for non-carbonated drinking water for washing water in consideration of such problems. If cold water is mixed in after the preparation, the gas volume of the carbonated drinking water will be reduced, and the air will be lost. Therefore, if the washing water is limited to one of the carbonated water and the cold water, the use of a different dilution water may lead to a decrease in the product of the drinking water to be provided.

Accordingly, an object of the present invention is to provide a dispenser capable of dispensing washing water in accordance with dilution water in order to solve the above-mentioned problem.
