[0014]

[Table 1]

[0015]

[Table 2]

The control operation of the water heater having the above structure will be described with reference to the flowchart of FIG. First, in step S1, the on / off states of the dip switches SW1 and SW2 are read out, and the data of the hot-water supply possible period corresponding to that state is read out from the RAM 33. In step S2, it is determined whether or not the read-out possible hot water supply period is unlimited. If it is, for example, 5 minutes here, the process proceeds from step S2 to step S3, and the bend that is output when the cup noodles are sold. Wait for the signal to be delivered. When the bend signal is supplied, the process proceeds to step S4 and the timer 35
Is started. In step S5, it is determined whether the hot water temperature is appropriate and the hot water supply enable signal is output. If the hot water supply enable signal is output, the door open / close detection switch 29 closes the open / close door 13 of the hot water supply room 12 in step S6. If it is closed, it is further determined in step S7 whether or not the cup noodle 2 is set at the predetermined hot water supply position by the cup detection switch 27, and if it is set,
If the hot water supply button 14 is turned on in step S8, the hot water valve 26 is opened and the hot water in the hot water tank 22 is supplied to the cup noodle 2. In step S10, the timer 35 is reset, and then the process returns to step S6.

As described above, since the timer 35 is cleared every time the hot water valve 26 is opened and hot water is supplied, the timer 35 does not time up during hot water supply. Therefore, even if the hot water supply is prolonged, the hot water supply is not interrupted. Even when the hot water supply enable signal is turned off during hot water supply, the hot water supply currently being performed can be continued as it is.

When the hot water supply is completed and the opening / closing door 13 is opened and the cup noodle 2 is taken out, the process proceeds from step S6 or step S7 to step S11. Since the time is up and the hot water supply state is ended by this, even if a person who has not purchased the cup noodle 2 turns on the hot water supply button 14 thereafter, hot water is not supplied.

On the other hand, if the hot water supply period is set to unlimited by the dip switches SW1 and SW2, the process proceeds from step S2 to step S12. When the door 13 is closed and the cup noodle 2 is present, the process proceeds from step S12, S13 to step S14, and while the hot water supply button 14 is on, the step S1 is performed.
At 5, the hot water valve 26 is opened to supply hot water. In this way, if the hot water supply period is unlimited, it is possible to always receive hot water without purchasing the cup noodle 2.

If only the cup noodle 2 is purchased and no hot water is supplied, the process proceeds from step S7 to step S11.
After 5 minutes, the time is up and the hot water supply ready state ends.

In the flow of FIG. 3, in order to guarantee the hot water supply for one cup, the timer 35 is cleared at the time when the hot water valve 26 is opened to delay the hot water supply period. The timer 35 may be cleared when the opening / closing door 13 is opened / closed for receiving. or,
The hot water supply device 11 has been described as being installed side by side with the cup noodle vending machine 1, but it may be incorporated into the cup noodle vending machine 1 in an integrated structure.

[0022]

As described above, according to the present invention, since hot water can be supplied only during the preset hot water supply period after the purchase of cup noodles, it is possible to prevent illegal hot water supply. If the hot water supply period elapses, hot water supply will not be possible after that, but if the hot water supply operation is performed before the hot water supply available period elapses, one cup of hot water supply is guaranteed, so it is troublesome because it is unfamiliar. However, the hot water supply will not be interrupted. If the hot water supply period is sufficiently long, it can be provided as a simple hot water supply device.
