Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved invention for a vending machine combined with a cooking device.

Generally, in such vending machines, the user puts the refrigerated or frozen food taken out into a cooking device such as a microwave oven and cooks it. If the operation is enabled automatically for a certain amount of time, if the next selling operation is performed while the previously sold food is still being cooked in the cooking device, i.e.
When continuous sales occur, it is necessary to operate the control timer that is already running so that the food that is subsequently taken out can also be cooked, but conventional products do not take this into account. There wasn't.

The present invention was invented in view of such problems, and when the food that has been taken out first is being cooked,
When food is taken out in the next vending operation, the present invention aims to provide a vending machine that can also cook the latter food following the heating of the light food.

Hereinafter, one embodiment will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a vending machine according to the present invention. A microwave oven 2 as a cooking device is placed on the top surface of the vending machine 1, and is electrically connected with a lead wire 10. FIG.

One of the vending machines 1 stores food products by type in refrigerated or frozen storage, and when a predetermined coin is inserted into a coin slot 3, a selection button 4 is pressed. When an operation is performed, the food corresponding to the selection operation is taken out to the outlet 5.

In addition, the other microwave oven 2 is energized while the control timer T (to be described in detail later) provided in the vending machine 1 is in operation, and is enabled to operate, and the door 6 is opened while it is enabled for vending. When the food taken out from the machine 1 is put in and the cooking switch 7 is operated, the built-in cooking timer (not shown) is activated.
It is configured such that the food can be heated in a set time of .

The above is an overview of the vending machine.Next, the operating circuit will be explained.

The circuit shown in FIG. 2 is its operating circuit, and as is clear from the figure, the first relay X1 and the control timer T second relay X2 are inserted in parallel to each side of the AC power source A-C. , and a third relay X3, which operates the drive circuit (including the timer, magnetron, etc.) 9 of the microwave oven 2 as a load.

When the carry-out detection circuit 8 inserted in series detects the movement of food quantity in the carry-out device 10 and outputs a carry-out detection signal, the first relay X1 outputs a carry-out detection signal as shown in the waveform diagram of FIG. It is a relay that operates for a time period, and its normally open relay contact X1-1a is inserted in series with the second relay X2, and its normally closed relay contact X1-1b is inserted in series with the timer T. .

The second relay X2 operates when the relay contact X□-1a is turned on based on the operation of the first relay X1 and is energized via the normally closed contact T-1b of the control timer T, The normally open contact X2-2a is turned on to form a self-holding circuit, and the control timer T and the third relay
This is a relay that turns on the normally open relay contacts X2-1a and X2-3a inserted in series with No.3.

Furthermore, when the relay contact X2-1a is turned ON and energization is started via the relay contact X1-1b, the control timer T is activated for a predetermined period of time (see Fig. 3).
This is a timer that operates for a time T1) shown in the waveform, and at the same time as the operation ends, that is, time-up, the normally closed timer contact T-1b is turned OFF to cut off the self-holding of the second relay X2, and the relay contact X2 -1a OF
It is configured so that its own electric circuit is also cut off by F.

Further, when the relay contact X2-3a is turned on by the operation of the second relay X2, the third relay X3 is energized and operates, and the third relay Open relay contact X3-1 a, X3-2
This is a relay that turns on a.

The present invention is constructed as described above, and its operation will be explained below.

Note that the above-mentioned vending machine can be considered to perform a single vending operation or to vend several times in succession, but first, the single vending operation will be explained.

Now, when the user inserts a predetermined coin into the coin slot 3 of the vending machine 1 and operates the selection button 4 to perform a so-called purchase operation, the desired food is delivered by the appropriate operation of the delivery mechanism. They are carried out one by one to the outlet 5.

On the other hand, when the food is carried out, the carrying out detection circuit 8 outputs a carrying out detection signal and supplies it to the first relay When X□-1a is turned on, relay contact X1
-1b is turned off once.

Then, in conjunction with this relay contact X1-1a turning on, the second relay contact ONL control timer T for X2-1a
Enables energization to.

Immediately after this, the operation of the first relay X□ is completed and the relay contact X1-1b is turned ON again, and the control timer T starts operating from the ON of the contact X1-1b (see Fig. 3). (see waveform).

In addition, in conjunction with the operation of the second relay X2, another relay contact X2-3a is turned ON, and the third relay X3 is operated to turn on the relay contact X31atx32a, thereby connecting the lead wire 10 to the microwave oven drive circuit 9. The microwave oven 2 is made ready for operation by the drive circuit 9 (see the waveforms in FIG. 3 and 5).

In this way, the operation circuit operates in conjunction with the operation of taking out the food, and electricity starts to be supplied to the microwave oven 2, making it ready for operation. Since the settings have already been made when the food is taken out, the food can be heated by simply turning on the cooking switch 7 after the user places the food in the microwave oven 2 and closes the door 6.

The actual heating time for this food is not the operating time T1 of the control timer T (operable time T2 of the microwave oven 2), but the time H set by the cooking timer built into the microwave oven 2 (see Fig. 3, 6). (see waveform).

Therefore, when the time H has elapsed, even though the control timer T is in operation and the microwave oven 2 is ready for operation, the heating of the food is finished and a notification to that effect is sent to the alarm. .

After confirming the notification from the alarm, the user should open the door 6 and take out the food.

Thereafter, when the operating time of the control timer T elapses, that is, when the timer T times out, the timer T turns off the timer contact T-1b and the second
The self-holding circuit of relay X2 is cut off, the second relay X2 is made inactive, and the relay contacts X2-1 a, X2
-2a and X2-3a are respectively turned off.

Therefore, with the non-operation of the second relay X2, the electric circuits of the control timer T and the third relay X3 are cut off, and the third relay X3 turns off its relay contacts X31a and Cut off the electrical circuit to microwave oven 2.
is in a non-operable state.

The above is a one-time sales operation, and next, continuous sales will be explained with reference to the waveform diagram in FIG. 4.

Now, when the first food is carried out to the take-out port 5 by the user's purchase operation, the first relay X1 is operated by the operation of the carry-out detection circuit 8 as explained above, and the second relay X2, The third relay X3 operates together to make the microwave oven 2 ready for operation, and the control timer T starts its operation.

Therefore, when the user puts the first food into the microwave oven 2 and turns on the cooking switch 7, the food is heated as described above.

Now, while the first food is being heated in this way (when the timer T has not yet passed the time t1 since the start of operation, that is, when the relationship tl<T1), the user performs the next purchase operation. When the second food is carried out to the takeout port 5, the carry-out detection circuit 8 is activated again and the first relay X1 is operated again. In response to this, 1b temporarily cuts off the electric circuit of the control timer T (0 part in the waveform diagram in FIG. 4), returns the timer T to its original starting point, in short, to the beginning (for example, sets the count to 0), Stop that operation.

During this time, both the second relay X2 and the third relay X3 are in operation, so the microwave oven 2 continues to be in operation.

Therefore, when the operation of the first relay X1 is completed,
Since the relay contact X knee 1b is turned on again, the control timer T starts operating and starts counting again from the beginning.

While the operation circuit is operating in this way or after that, when the first heating of the food is completed (see Figure 4, 6), the alarm will notify you of this, and the user will be informed accordingly. Then, by removing the first food from the microwave oven, putting the second food into the microwave oven 2, and turning on the cooking switch 7 again, the second food can be cooked successively.

Furthermore, while the food is being heated for the second time in this way (when only time t2 has elapsed since the start of the second operation of timer T, provided that t2<T□), the user When the purchase operation is performed again and the food is taken out for the third time, the first relay As shown in the 0 part of the waveform diagram, the electric circuit is cut off and the operation stops, and it returns to the original starting point (initial).
Wait until relay X1 becomes inactive.

Of course, during this time, both the second relay X2 and the third relay X3 are in operation, keeping the microwave oven 2 in operation and heating the food for the second time.

When the operation of the first relay X1 is completed, the relay contact X1-1b is turned ON again, so the control timer T starts operating and starts counting again from the beginning.

When the operation circuit is operating in this way or after that, the alarm will notify you again when the second food heating is completed, and the user will then be able to electronically heat the food for the second time. By removing the food from the microwave, putting the third food into the microwave oven 2, and turning on the cooking switch 7 again, the third food can be cooked successively.

When the third heating of the food is completed, the alarm is activated again to notify the user of this fact, and the user only has to remove the food from the microwave oven 2.

Thereafter, when the operating time of the control timer T has elapsed, the control timer T turns off the timer contact T-1b.

Therefore, with the non-operation of the second relay X2, the control timer T and the third relay X3 are disconnected from each other, and the third relay X3 has its relay contacts
A is turned off to cut off the electric path to the drive circuit 9 and put the microwave oven into a non-operable state.

The present invention electrically connects a cooking device that operates for the time set by a cooking timer by operating a cooking switch, and when a purchase operation is performed, the stored food is taken out, and at the same time, the control timer is activated. In the vending machine that operates the cooking device to enable operation for a predetermined period of time, the control timer is configured to start operating from the beginning every time food is taken out, and the control timer is configured to start operating from the beginning every time food is taken out, and the control timer is configured to operate the cooking device when the control timer starts operating. Since the device is designed to remain operational until the control timer times up, even if the next food is brought out while the previously taken out food is being put into the cooking device and cooked, the This is an excellent invention that allows food to be carried out at a later date to be cooked after the food is cooked.
