BACKGROUND OF THE INVENTION This invention is to automatically supply tea by pressing a tea supply button to energize and open a water valve and supply hot water to a tea strainer containing tea leaves. It relates to a dispenser.

[0002]

2. Description of the Related Art Conventionally, as an automatic tea dispenser which is a dispenser, for example, an automatic tea dispenser body and a cup feeder are integrated, and a cup feed button of the cup feeder is pressed to make a cup at a cup outlet. It is known that tea is supplied, the cup is placed on the tea outlet, and the tea is pressed into the cup by pressing the tea supply button.

[0003]

In the automatic tea dispenser configured as described above, even if the tea leaves in the tea canal are lost, the user cannot know the fact, and therefore the tea supply Even if the button is pressed, only hot water comes out, which causes inconvenience to the user.
The purpose of this invention is to provide a dispenser in which there is no raw material in the raw material container 13 and the drive motor M is stopped at that time.

[0004]

DISCLOSURE OF THE INVENTION A dispenser according to the present invention comprises a counter C electrically connected to a drive motor M for counting the number of times the drive motor M is driven, and a counter C electrically connected to the counter C. When the driving frequency of the driving motor M reaches the number of times when the raw material in the raw material container is exhausted, the driving motor M is energized and excited, and after excitation for a predetermined time, the driving motor M is deenergized to drive the driving motor M. A protective timer TM to be stopped, and a display section electrically connected to the protective timer TM and energized at the same time when the drive motor M is stopped to be lit to display that there is no raw material in the raw material container 13.
It is equipped with 11 and.

[0005]

According to the present invention, the protection timer TM cuts off the power supply to the drive motor TM after a predetermined time elapses after the number of times the drive motor M is driven reaches the number of times when the raw material in the raw material container is exhausted. Then, the driving of the driving motor M is stopped, and at the same time when the driving motor M is stopped,
11 is energized and lit, and it is displayed that there is no raw material in the raw material container 13.

In the automatic tea dispenser 5 thus constructed, the cup is supplied to the cup outlet 23 by pressing the cup discharge button (not shown) of the cup supply device 7. Then, the user desires tea and presses a tea button (not shown) on the operation board 30 to electrically connect the fourth terminal T ₄ and the first terminal T ₁ on the control board PCB. Connected, the first water valve W
V ₁ and the first relay X ₁ are excited, the first water valve WV ₁ is opened, the hot water in the hot tank 18 passes through the tea strainer 15 to become tea, and the tea is poured into a cup. Normally, the cup is filled with tea in a few seconds,
If the first water valve WV ₁ continues to be excited and released due to some abnormality, the first relay X ₁ also continues to be excited and the normally open contact X ₁₁ of the first relay X ₁ continues to close, resulting in protection. The timer TM for use also continues to be excited. When the protection timer TM has passed a preset time, the normally open contact TM _a is closed, the display unit 11 is energized and lit, and the abnormality of the water valve WV ₁ is displayed. At the same time, the normally closed contact TM _b opens, and as a result, the first water valve W
The power supply to V ₁ , the second water valve WV ₂ , the drive motor M and the fan 22 is cut off and the function as a dispenser is stopped. In addition, when the user desires hot water and presses the hot water button (not shown) on the operation board 30,
4th terminal T ₄ and 2nd on control board PCB
Is electrically connected to the terminal T ₂ of the same, the second water valve WV ₂ and the second relay X ₂ are excited, the second water valve WV ₂ is opened, and the hot water in the hot tank 18 is Pour into cup through ₂ water valve WV ₂ .

Normally, the cup is filled with hot water within a few seconds, but if the second water valve WV ₂ continues to be excited and released due to some abnormality, the second relay X ₂ also continues to be excited, and The normally open contact X ₂₁ of the _second relay X ₂ continues to be closed, and as a result, the protection timer TM also continues to be excited. Then, when the protection timer TM has passed a preset time, the normally open contact TM _a of the protection timer TM is closed, the display unit 11 is energized and lit, and the abnormality of the water valve WV ₂ is displayed. At the same time, the normally closed contact TM _b of the protection timer TM
Are opened, and as a result, the first water valve WV ₁ , the second water valve WV ₂ , the drive motor M and the fan 22 are opened.
The power supply to the device is cut off and the function as a dispenser is stopped.

Further, normally, when it comes time to exchange tea leaves, the fourth terminal T ₄ and the third terminal on the control board PCB
Is electrically connected to the terminal T _{3 of} the driving motor M and the third relay X ₃ is energized and excited, the driving motor M is driven, and the tea leaves in the tea strainer 15 are in the tea barrel 13. Will be exchanged for tea leaves. However, if the drive motor M is driven due to some abnormality and the third relay X ₃ continues to be excited, the normally open contact X ₃₁ of the third relay X ₃ continues to close, and as a result, the protection timer TM also. Continue to excite. When the protective timer TM has elapsed the predetermined time, it closed normally open contact TM _a protective timer TM, the display unit 11 lights are energized, the abnormality of the drive motor M is displayed. At the same time, it opens the normally closed contact TM _b of the protection timer TM,
As a result, the power supply to the first water valve WV ₁ , the second water valve WV ₂ , the drive motor M and the fan 22 is cut off, and the function as a dispenser is stopped.

Furthermore, depending on the amount of tea leaves that enter the tea barrel 13,
The number of tea exchanges can be decided, but that number has been reached
When the tea leaves in 13 run out, the function as a dispenser stops. That is, each time the drive motor M is energized and driven, the normally open contact X ₃₁ of the third relay X ₃ is closed, and the counter C is connected to the counter C through the fifth terminal C ₅ and the sixth terminal C _6. Enter the number of tea leaf exchanges. When the preset number of tea leaf exchanges is reached, the second terminal C ₂ of the counter C is reached.
And the third terminal C ₃ are electrically connected, and the protection timer TM is energized. Then, when the protection timer TM has passed a preset time, the normally-open contact TM _a of the protection timer TM is closed, and the display unit 11 is energized and lit,
It is displayed that there are no tea leaves in the tea barrel 13. At the same time, opened normally closed contacts TM _b of the protective timer TM, as a result the first water valve WV _1, second water valve WV _2, as is blocked dispenser energization of the driving motor M and fan 22 Will stop functioning. In addition, although the automatic tea dispenser has been described as the dispenser in the above embodiment, the present invention can be applied to an automatic tea machine, an automatic coffee machine, and the like. Further, in the above embodiment, the automatic tea dispenser 5 and the cup supply device 7 are separated, but the dispenser and the cup supply device are integrated to directly supply the cup to the tea outlet. The device can be applied.

[0012]

As described above, in the dispenser of the present invention, the display timer 11 is energized by the protective timer TM after the number of times the driving motor M is driven reaches the number of times when the raw material in the raw material feeding portion 13 is exhausted. Is turned on, and the drive of the drive motor M is stopped.
The drive motor M of the raw material exchange mechanism does not operate when the raw material is empty, and the user knows from the display unit 11 that the raw material in the raw material container 13 is empty. You can
