Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rinse device of a cup mixing type vending machine which pours hot water into a cup and melts the raw material while stirring in the cup.

Conventional technology As a cooking method for melting powdered raw material in hot water, put the raw material and hot water in a mixing bowl, stir the inside of the mixing bowl with a stirrer, and pour the sufficiently melted mixture into a cup. In addition to the traditional method, a cup mixing method is known as a hygienic cooking method that does not use a mixing bowl or a stirring device.

The cup mixing device is constructed as shown in FIG. The hot water injection system of this device, in which the raw material is charged into the cup 1 and then the hot water 2 is vigorously injected into the cup 1, is configured as follows.

The amount of hot water 2 required for one sale is supplied to the pressurized tank 4 via the valve 3, and then the valve 3 is closed to supply the pressurized air 5 to the pressurized tank 4. . The supply of the pressurized air 5 increases the internal pressure in the pressure tank 4, and the hot water supplied to the pressure tank 4 vigorously flows into the pipe 6 due to the increased internal pressure. The flow path of the pipe 6 is cheese 7.
Is divided into channels 8a and 8b by the channel 8a
Connected to a first nozzle 9 oriented directly below
The flow path 8b is connected to a second nozzle 10 which is oriented obliquely along the cup side wall 1b.

The hot water sprayed from the first nozzle 9 collides with the cup bottom 1a and becomes a turbulent flow C that rotates in the vertical direction, sufficiently agitates the mixed liquid D of the raw materials, and is sprayed from the second nozzle 10 The flow E along the cup side wall 1b serves to reduce the foaming of the mixed liquid D generated by the turbulent flow C.

The conventional rinsing device has a cup station 11 and a cup 1
Hot water 2 from the first and second nozzles 9 and 10 without discharging
When a raw material extraction device is provided inside the pressure tank 4 or in place of the pressure tank 4, for example, a raw material extraction device for forcibly filtering the raw material made by milling coffee beans is provided. The inside of the raw material extracting device is washed without being supplied to the drainage container, collected in the tray 12 and drained to the drainage bucket 14 via the hose 13.

In order to increase the cleaning efficiency of the pipe 6, the pressure of the pressurized air 5 is the same as that at the time of normal sale even in the rinse state.
The washed hot water 2 is sprayed from the first and second nozzles 9 and 10 to the cup station 11.

Problems to be Solved by the Invention With such a conventional configuration, the cleaning water sprayed from the second nozzle 10 during rinsing comes off the tray 12 to wet the inside of the vending machine.

It is an object of the present invention to provide a rinse device in which washing water does not come off from a tray and wet the inside of a vending machine when the rinse is performed.

Means for Solving the Problems The rinsing device according to claim 1 injects hot water vigorously from a first nozzle for pouring hot water toward the bottom of the cup and obliquely along the side wall of the cup. In a vending machine that uses a second nozzle to melt a raw material that has been put into a cup, a valve that opens and closes a flow path to the second nozzle and a control that detects a rinse execution instruction and closes the valve. It is characterized by having a section.

The rinsing device according to claim 2 controls the valve by discriminating between a valve that arbitrarily switches the flow rate to the second nozzle to a set flow rate and a column that is performing sales, and does not detect a rinse execution instruction. At the time of sale, when the valve is fully opened and a rinse execution instruction is detected, the valve is provided with a control unit for limiting the flow rate to the second nozzle to a specified amount.

According to the configuration of claim 1, in the rinse execution state, the control unit closes the valve provided in the flow path to the second nozzle,
Hot water is sprayed only from the nozzle.

According to the configuration of claim 2, in the rinse execution state, the control unit limits the flow rate to a specified amount by the valve provided in the flow path to the second nozzle, and the first nozzle jets vigorously, The hot water discharged from the nozzle is slowly discharged so as not to fly to a distance.

Embodiment An embodiment of the present invention will be described below with reference to FIG. In addition, what has the same effect as that of FIG.
Description will be given with the same reference numerals.

In the rinse apparatus according to the first aspect, as shown in FIG. 1, a pinch valve 15 is arranged in the flow path of the second nozzle 10. Every time the control unit 16 detects the rinse execution instruction 17, the pinch valve 15 is closed until the rinse is completed.

Due to this configuration, the first and second products are sold normally.
In a rinse state in which hot water is sprayed from the nozzles 9 and 10 of the nozzle 1 into the cup 1 to mix the cup for cooking, and the controller 16 detects the rinse execution instruction 17, the flow path 8b to the second nozzle 10 has the pinch valve 15 Is maintained in a closed state, the injection from the second nozzle 10 is prohibited, and the hot water 2 is entirely in the first nozzle 9
It is jetted toward the cup station 11 from. Therefore, the whole amount of the washed hot water 2 will not be reliably received by the tray 12 and spilled into the vending machine.

In the above-described embodiment, the flow path of the second nozzle 10 is kept closed by the pinch valve 15 for the rinse period. However, as described in claim 2, the flow to the second nozzle 10 is increased. As a valve provided in the passage, a valve whose flow rate can be arbitrarily switched to a set flow rate is used, and during the rinsing period, it is configured to be reduced by a specified amount as compared with that during normal cup mixing, so that the injection from the second nozzle 10 It is also possible to reduce the momentum so that the washed hot water 2 discharged from the second nozzle 10 is received by the saucer 12.

As described above, according to the configurations described in the claims, the rinse execution instruction is detected, and the control unit controls the valve to control the discharge amount from the second nozzle. It is possible to avoid the situation where the spillage occurs in the vending machine.
