Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a coffee vending machine (hereinafter referred to as a vending machine) that is capable of dispensing standard coffee and light coffee that is thinner than standard coffee. This type of light coffee is usually called American coffee, so the following explanation will also be referred to as American coffee.

2. Description of the Related Art Coffee vending machines that are capable of dispensing standard coffee and American coffee according to one's choice have been known.

However, in conventional coffee vending machines of this type, the supply times for coffee raw materials, sugar, and cream are set independently of the three timers that set the supply times for coffee raw materials, sugar, and cream for standard coffee. A total of three timers are provided for American coffee, and when American coffee is selected, fewer coffee ingredients and selections are available than for standard coffee, according to the supply time set by the timer for American coffee. Since the system was designed to supply cream and sugar, the structure was complex, and it also had the disadvantage of being inefficient from a functional standpoint.

The present invention was made in view of this problem, and basically, a standard coffee vending machine is provided with an American button for specifying American coffee, and when the American button is operated, the coffee raw material and the selection are available. By reducing the amount of cream and sugar at a predetermined ratio compared to standard coffee,
The purpose of the present invention is to provide a coffee vending machine with a button for light coffee that can dispense American coffee.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In FIG. 1, 1 is a control circuit for a coffee vending machine constituted by a microcomputer, 2 is a coin selector, and 3 is a selection switch that is selectively operated by a standard coffee selection button and an American coffee selection button. device, 4
5 is a group of loads driven for the output time set by control circuit 1, such as motors M ₁ , M ₂ and M ₃ for supplying coffee powder, sugar and cream, and hot water valve SV ₁ ; 5 is for standard coffee; , output time setting digital switches DS ₁ , DS ₂ , ... that set output times for load groups such as coffee supply motor M ₁ , sugar supply motor M ₂ , cream supply motor M ₃ , hot water valve SV ₁ , etc. It is equipped with an output time setting section.

As shown in FIG. 2, the selection buttons for operating the selection device 3 include a selection button S 1 for standard coffee set to a normal coffee concentration, a black coffee selection button S _{1 for adding no sugar or cream, and a selection button S 1} for coffee with sugar, which adds only sugar. Selection button S ₂ , Coffee with cream selection button that only adds cream S ₃ , Coffee selection button with sugar and cream that adds sugar and cream
S ₄ , Black coffee selection button for American coffee with a coffee concentration lighter than standard coffee A ₁ , Sugar-sweetened coffee selection button
_A2 , etc., so that the customer can press any one selection button according to his/her preference.

The control circuit 1 controls the coffee supply motor M1, the sugar supply motor _{M2 ,} and the hot water valve when any one selection button for standard coffee, for example, the sugar-added coffee selection button _S2 is pressed.
Each predetermined output time is outputted to the SV ₁ by the output time setting section 5, and standard coffee containing sugar is prepared.

On the other hand, the selection buttons A ₁ , A ₂ for American coffee
etc., the control circuit 1 causes the coffee supply motor _M1 , sugar supply motor _M2, etc. to output an output time t preset by the output time setting section 5. ₁ , t ₂ , . . . output times t ₁ ′, t ₂ ′, .

The above output time for standard coffee t ₁ , t ₂ ,
Output time t ₁ ′ for American coffee for …
Ratio of t' ₂ ,... r ₁ , r ₂ ,... (r ₁ = t' ₁ /t ₁ , r ₂ = t' ₂ /t ₂
,
The weight loss rates r ₁ , r ₂ , ... given as (...) may be incorporated in advance as a program in the control circuit 1, and as shown in FIG. 4, the output time setting section 5
2 to set these weight loss rates r ₁ , r ₂ ,...
Digital switches DA ₁ , DA ₂ , etc. are provided to set the weight loss rate of coffee to 80%, the weight loss rate of sugar to 50%, and the weight loss rate of cream to 70% according to your preference. It may be possible to do so.

In addition, as shown in FIG. 3, in addition to the standard coffee selection buttons S ₁ , S ₂ , ..., a single selection button A for American coffee selection is provided, and the American coffee selection button A and the standard coffee selection button A desired type of American coffee may be prepared by operating the selection buttons S ₁ , S ₂ , . . . in combination.

That is, for example, American coffee selection button A
When the standard coffee with sugar selection button S ₂ is pressed, the control circuit 1 causes the coffee supply motor M ₁ and the sugar supply motor M ₂ to output the output time t ₁ ′ shortened by a predetermined reduction rate, respectively. , t ₂ ′ and prepare American coffee with sugar.

As is clear from the above description, the present invention provides at least one method for selecting American coffee.
In addition, when the American button is pressed, coffee and sugar are added at a predetermined reduction rate relative to the amount of coffee, sugar, cream, etc. in the case of standard coffee. The present invention provides an American coffee vending machine with a button, characterized in that it is provided with a control circuit for controlling each supply means so as to supply cream and/or cream.

According to the coffee vending machine with an American button according to the present invention, by shortening the preset supply time of each ingredient of standard coffee by a predetermined ratio and calculating the supply time of each ingredient of American coffee, Therefore, by simply adding at least one American button, standard coffee and American coffee can be blended arbitrarily and without complicated control.
