Description

[Detailed description of the invention] The present invention provides coffee without additives (black coffee).
, coffee with cream, coffee with additives such as sugar, etc. can be selected using a selection switch, and when coffee with additives is selected, the amount added can be increased by one level by pressing the increase switch corresponding to the additive. A coffee vending machine with a refill function (hereinafter referred to as a vending machine).

). As a matter of fact, the above-mentioned coffee rice machine with a capacity increasing function is well known.

However, with conventional coffee rice machines with an increase function,
For example, if you select coffee with cream, you can only increase the amount of cream, and even if you press the increase switch for sugar, which is not specified as an additive, sugar will not be added. There was a problem that it was impossible to realize.

The present invention has been made in view of such problems, and includes:
Using the increase switch, for example, when you select coffee with cream, if you press the increase switch for something other than cream, such as the sugar increase switch, you can add less sugar than the usual amount to match the cream. The purpose of the present invention is to provide a coffee rice machine with an intermediate increaser.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments. In FIG. 1, 1 is a control device that controls the entire coffee rice machine, 2 is a coin machine, and 3 is coffee without cream or sugar (hereinafter referred to as black coffee).

), coffee to which only cream is added (hereinafter referred to as coffee with cream), coffee to which only sugar is added (hereinafter referred to as coffee with sugar), coffee to which both cream and sugar are added (hereinafter referred to as stand coffee). ) is a selection device equipped with selection switches 4, 5, 6, and 7 for selecting a total of four types of coffee; 8 is a raw material motor for supplying coffee and necessary additives to the cup based on commands from the control device 1; , the load on the supply system such as the solenoid of the solenoid valve, 9 a cream volume increase switch, 10 a sugar volume increase switch, 11 a mode changeover switch for switching between a mode in which intermediate volume increase is possible and a normal volume increase only mode, which will be described later. This is a two-digit digital switch that sets the intermediate increase rate. The control device 1 receives the output signal from the coin mech 2, and when any one selection switch is pressed, if the pressed selection switch is, for example, coffee with cream, a certain amount of coffee is supplied to the control device 1. a selection switch response control circuit 13 that outputs a necessary command signal to supply a certain amount of cream; and increase switches 9 and 1;
A quantity increase control circuit 14 that outputs an additive quantity increase command signal when at least one of 0 is pressed, and a quantity increase control circuit 14 that outputs an additive quantity increase command signal when at least one of It has a built-in timer circuit 15 that sets the output time, and when only one of the selection switches is pressed and the increase switches 9 and 10 are not pressed at all, a fixed amount of coffee and the selected selection switch are produced. For example, in the case of coffee containing cream, the usual control is to supply a certain amount of cream to the set cup.

As the increase control circuit 14, for example, a logic circuit as shown in FIG. 2 can be used.

In FIG. 2, as mentioned above, 4, 5, 6, and 7 are selection switches corresponding to black coffee, coffee with cream, coffee with sugar, and standard coffee, respectively, and 9 and 10 are cream increase switches and sugar increase switches, respectively. For each selection switch, each pair of AND gates 40, 41, 50, 51, 60, 61,
70 and 71, and a total of four OR gates 16 and 17, each pair of AND gates outputting the same type of gate output signal, for example, the output signals of 40 and 60 as input signals.
, 18 and 19 are provided to constitute the increase control circuit 14. One input terminal of each pair of AND gates, for example 40 and 41, is connected to the black coffee selection switch 4, and the other input terminal of the AND gate 40 is connected to the cream increase switch 9, and the other input terminal of the AND gate 41 is connected to the black coffee selection switch 4. The terminals are regularly connected to the corresponding selection switch and either the cream increase switch 9 or the sugar increase switch 10, such that the sugar increase switch 1 is connected.

Taking the black coffee selection switch as an example, if you press the black coffee selection switch 4 and then press the cream increase switch 9, for example, the output of the AND gate 40 rises, and the cream increases through the OR gate 16. An intermediate increase signal Cm is output.

Therefore, in this case, for example, the ratio to the normal cream addition amount set by the intermediate increase ratio setting digital switch 12 (for example, as shown in FIG. 1,
40%) cream can be added to black coffee. Further, when the sugar increasing switch 10 is pressed after the cream increasing switch 9 or without pressing the cream increasing switch 9, the output of the AND gate 41 rises and the intermediate sugar increasing signal S is sent via the OR gate 17.
m is output and thus black coffee with a small amount of sugar is prepared. Further, for example, if the cream added coffee selection switch 5 is pressed and then the cream increase switch 9 is pressed, the output of the AND gate 50 rises, and a certain amount is added to the normal amount of cream added via the OR gate 18. , a so-called cream IJ cream normal increase signal Ci is output, and the cream is normally increased. In addition, when the sugar increase switch 10 that is not specified by the selection switch 5 is pressed, the AND gate 51 rises and the intermediate sugar increase signal Sm is outputted via the OR gate 17. teeth,
A small amount of sugar will be added.

Incidentally, when one of the selection switches 4 to 7 is pressed but the increase switches 9 and 10 are not pressed, the increase signal C
Since m, Sm, Ci, and Si are not output, it goes without saying that the additive specified by the selection switch pressed is controlled to be added to a certain amount of coffee in the usual amount (standard amount). Nor.

That is, when selection switch 5 is pressed, cream is added in the normal amount, when selection switch 6 is pressed, sugar is added in the usual amount, and when selection switch 7 is pressed, cream and sugar are added. Sugar is added in the usual amount, and nothing is added when the selection switch 4 is pressed. The above-mentioned increase control methods are summarized in the following table. Table As is clear from this table, in the present invention, selection switches 4 to 7 can be used to increase the amount of additives that are not specified, such as cream and sugar for black coffee, sugar for coffee with cream, etc. When pressed, a small amount of the additive corresponding to the increase switch can be added together with the designated additive (intermediate increase).

Therefore, whereas in the past, only four normal increases could be performed, the present invention can perform eight ways of increase control including intermediate increases, making it possible to better adapt to customer preferences.

In the above embodiment, the increase control circuit 14 using logic elements has been described, but in a coffee vending machine incorporating a microcomputer, the increase control shown in the table above may be performed by a program.

Further, it goes without saying that the mode changeover switch 11 and the intermediate increase ratio setting switch 12 can be omitted depending on the case.

As is clear from the above explanation, in the coffee making machine according to the present invention, by pressing the corresponding increase switch, it is possible to add a certain amount of additives that were not specified by the selection switch, and the operation is simple. This provides the advantage of being able to mix additives according to one's preferences without complication.
