Description

[Detailed description of the invention] The present invention uses a mixing means to appropriately mix the beverage raw materials and diluent that are delivered to the mixing means in response to a delivery signal, etc. to obtain the desired drinking water, and then place the drink in a receiving port or the like in advance. This invention relates to a mixing device for an automatic beverage dispenser that supplies beverages to cups and the like that are being sold.

Looking at this type of conventional device, as shown in FIGS. 1 and 2, the beverage raw material discharged from the raw material container 1 is transferred from a liquid tank (not shown) by a mixing ball 3 in a mixing means 2. After being mixed in advance with the supplied diluted liquid such as hot water, it is subjected to the mixing action of the mixing blade 41 in the mixing case 4 of the mixing means 2, and is supplied onto the cup 6 from the supply nozzle 5. .

However, in this conventional device, the supply port 42 between the mixing case 4 and the supply nozzle 5 is always open, so that part of the beverage raw material and diluent being mixed in the mixing case 4 is If the mixture is not mixed sufficiently, it will flow down into the cup 6 through the supply nozzle 5, spoiling the taste.

The present invention was devised in view of the shortcomings of the conventional devices, and the purpose is to provide a mixing device in which the beverage raw materials and diluent that are being mixed do not flow down into the cup through the supply nozzle. Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In Fig. 3, 11 is the main body of the feeder, 13 is the soup,
It is a raw material container that stores beverage raw materials (powder) such as coffee, and is installed on a shelf board 12 provided in the main body 11, and is provided at the bottom of the push button switch 15 whenever an unloading signal is issued in response to the operation. The unloading port 14 is opened by the operation of the unloading mechanism (not shown).
Beverage raw materials are transported through the facility.

16 is a mixing means, and as shown in FIGS. 4 and 5, a mixing bowl 18 receives the beverage raw materials and the diluent.
It has a carry-in port 19a at the top and a supply port 21 at the bottom, and furthermore, a mixing blade 20 rotated by a mixing motor (not shown) is provided on the horizontal axis inside. Consisting of a mixing case 19 and a supply nozzle, a mixing ball 18 is attached to a loading port 19a provided at the top of the mixing case 19, and a supply nozzle 24 is attached to a supply port 21 provided at the bottom. It is being

Further, a cylindrical body 22 having an outflow hole 23 cut out from the upper end is attached to the supply port 21 portion provided at the lower part so as to protrude into the case 19, as shown in FIG.

The present invention is constructed in a diagonal manner, and its operation will be explained below.

Now, when the pushbutton switch 15 is turned on, the mixing motor (mixing vane 20) starts to drive, and the liquid supply valve (not shown) and the delivery mechanism operate to drain the diluted liquid from the liquid tank. The beverage raw materials in the raw material container 13 are supplied to the mixing bowl 18 through the water supply pipe 17 and are also supplied to the mixing bowl 18 through the outlet 14.
It will be transported to

The beverage raw materials put into the mixing bowl 18 are somewhat decomposed into the diluent in the mixing bowl 18 and become drinking water, and then flow down into the mixing case 19 at the bottom and are mixed. Feather 2
0 mixing effect.

Inside this mixing case 19, the mixing blade 20 is rotating at a high speed in the direction of arrow A, so that the drinking water flowing inside the mixing case 19 due to the rotation of the mixing blade 20 reaches the bottom of the mixing case 19.
It collides with the upper end of the cylindrical body 22 and flows along arrow B as shown in the figure.

Therefore, at the bottom of this mixing case 19, the cylindrical body 2
A cavity C is formed at the periphery of the cylindrical body 22, and the drinking water does not flow down from the upper end opening 22' of the cylindrical body 22 toward the supply port 21 (even if it does, the amount is extremely small), but all of the water flows inside the mixing case 19. , subjected to mixing action.

When the desired drinking water is completed after a predetermined period of time, the mixing blade 20 stops rotating, and the drinking water is supplied from the opening 22' of the cylindrical body 22 to the supply port 2.
1 and is poured through a supply nozzle 24 into a cup 25 placed on a saucer 11' of the main body 11.

At the end, the drinking water present at the bottom of the mixing case 19 flows down through the outflow hole 23 of the cylindrical body 22, and all the drinking water in the mixing case flows out.

The present invention has a cylindrical body extending inward from the mixing case around the periphery of the supply port provided at the bottom of the mixing case, as shown in the above figure. Since the water does not flow down toward the supply port, the beverage raw materials and diluent are completely mixed, and this is an excellent device that can provide delicious drinking water.
