Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for cleaning and sterilizing the discharge nozzle of a dispenser for automatically dispensing drinks, etc. in cups.

[Conventional technology]

BACKGROUND OF THE INVENTION Recently, beverage dispensers for dispensing drinks, carbonated drinks, etc. in unmanned cups have come into widespread use due to their simplicity.

Generally, the nozzle of this dispenser is exposed to the outside air, and it cannot be said that the nozzle is always kept under sanitary conditions.

Therefore, in order to maintain the sanitary condition of the nozzle, conventionally, for example, the syrup in the syrup tank is collected, cleaning hot water is filled in the tank, and the cleaning hot water is discharged using pressurized gas such as carbon dioxide. It was cleaned and sterilized.

However, with such conventional techniques, a lot of time was required for cleaning, and moreover, a great deal of labor was required to collect the syrup.

In order to deal with such problems, for example, Japanese Utility Model Application Publication No. 53-136198 proposes an automatic cleaning and sterilization device for a drinking water outlet nozzle in a vending machine.

According to this device, the device is equipped with an injection nozzle near the drinking water outflow nozzle, and the injection nozzle automatically sprays the sterilizing liquid toward the drinking water outflow nozzle, and periodically sprays the sterilizing liquid toward the drinking water outflow nozzle. We are cleaning and sterilizing.

[The problem that the idea aims to solve]

However, in this method, the drinking water outflow nozzle is cleaned and sterilized by spraying a 75% ethyl alcohol sterilizing solution, so there is a problem that there is a lot of waste because the ethyl alcohol is consumed by evaporation during spraying. . Furthermore, since the ethyl alcohol cleaning liquid drips from the drinking water outflow nozzle, the contact time is short and the sterilizing effect is not sufficient. In addition, the inner surface of the nozzle, which requires cleaning and sterilization,
It is difficult to bring the lower end surface and the outer surface on the anti-spray side into contact with the cleaning sterilizing liquid, and even in the front of the spray, depending on the spray condition and the amount of spray, it is not always possible to contact the entire surface to be cleaned.

On the other hand, Japanese Patent Publication No. 46-9602 discloses a cleaning method for an outflow nozzle for milk dispensing in a milk vending machine;
There is a problem similar to that of Publication No. 136198.

In view of these circumstances, the present invention solves the above problems, makes it possible to reliably clean and sterilize drinking water outflow nozzles, and also cleans and sterilizes not only the outside surface of the nozzle, but also the inside surface, and even the lower end surface of the nozzle. An object of the present invention is to provide a cleaning and sterilizing device for a beverage dispenser nozzle that can be used.

[Means to solve the problem]

In order to solve the above problems, the present invention includes a cleaning and sterilizing container for storing a cleaning and sterilizing liquid to wash and sterilize a beverage dispenser nozzle, a hot water tank for storing a cleaning and sterilizing liquid to be supplied to the container, The cleaning and sterilizing device for a beverage dispenser nozzle includes a cleaning and sterilizing liquid supply mechanism for supplying a cleaning and sterilizing liquid stored in the hot water tank to a container, and the container includes a liquid receiver for retaining the cleaning and sterilizing liquid. , a weir disposed in a part of the liquid receiver to allow the cleaning sterilizing liquid to overflow, and a mounting part to be installed near the nozzle of the beverage dispenser, and continuously supplying the cleaning sterilizing liquid into the container. At the same time, a part of the cleaning sterilizing liquid is overflowed, and while exchanging the cleaning sterilizing liquid in the container, the dispenser nozzle is immersed in the cleaning sterilizing liquid retained in the container for a certain period of time, and the inside of the nozzle is The outer surface and lower end surface are configured to be cleaned and sterilized.

[Effect]

A cleaning and sterilizing container is attached to the lower side of the dispenser nozzle, and a cleaning and sterilizing liquid is continuously supplied into the container.

Then, the cleaning and sterilizing liquid flows into the liquid receiver of the cleaning and sterilizing container, and the liquid level of the cleaning and sterilizing liquid that has flowed into the liquid receiver gradually rises and reaches the lower end of the nozzle of the dispenser.

Furthermore, the liquid level rises and reaches the top of the weir of the liquid receiver, after which the old cleaning and sterilizing liquid pushed out by the freshly supplied cleaning and sterilizing liquid overflows. As a result, the cleaning and sterilizing liquid in the liquid reservoir is constantly replaced.

In this state, the inner and outer surfaces and lower end surfaces of the dispenser nozzle that require cleaning are immersed in hot water for a certain period of time to be cleaned and sterilized.
