DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice / water supply device for supplying ice and water for drinks to a container when a carry-out lever is pressed by a container such as a cup.

[0002]

2. Description of the Related Art Conventionally, this kind of ice and water supply apparatus is, for example, as disclosed in Japanese Utility Model Publication No. 51-14696 (F25C5 / 02), an ice making device, an ice storage container, and an electric outlet for opening and closing the ice outlet of the ice storage container. An ice making machine having an opening / closing door is provided with a water supply device including a water supply pipe, a water outlet, and a solenoid valve provided in the water supply pipe, and an open / close switch that can be pressed by a cup is provided, and the open / close switch is pressed by the cup. In this case, the electric door is opened to carry out ice into the cup, the electromagnetic valve is opened, water is supplied into the cup from the water outlet, and the cup is separated from the open / close switch to open the electric door. It is configured to close and stop water supply from the outlet.

[0003] Thus, the user can very easily store ice water in the cup simply by pressing the cup on the open / close switch.

[0004]

However, in the above-mentioned publication, since ice and water are simultaneously carried out into the cup, the ice falls when the water level in the cup rises due to the discharge of water, and water falls outside the cup. There is a problem that the splash of water splashes and the hand holding the cup and the surroundings get wet.

[0005] When the water supply pressure of the water supply device is high, water is discharged vigorously and the water level in the cup rises quickly. Some problems arise. Further, when carrying ice out of the ice storage container, an ice discharging member is provided in the ice storage container, and the ice in the ice storage container is sent to the ice outlet by rotating the ice discharging member. If the electric opening / closing door is closed while the vehicle is coming out of the vehicle, there is a risk that ice will be trapped between the ice outlet and the electric opening / closing door, so-called ice bite. If such ice bites occur, the ice outlet will not be completely closed even after the cup is released from the open / close switch, and ice will spill out from the ice outlet. For this reason, in Japanese Patent Application No. 3-55670 filed earlier by the applicant, the electric opening / closing door (door) is closed with a delay from the stop of the ice discharging member.

[0006] Here, in consideration of user's convenience, a fixed amount carrying mode in which a predetermined amount of ice is carried out by pressing an open / close switch by a glass, and a continuous carrying mode in which ice is continuously carried out while the open / close switch is pressed. When the setting is set, in the fixed quantity unloading mode, the ice is stopped before the cup is released from the open / close switch.Therefore, there is no problem even if the delay is performed, but in the continuous unloading mode, the electric opening and closing is delayed after the cup is released. The door is closed, and there is a problem that the ice being carried out spills out of the ice outlet during the delay time even after the ice discharging member is stopped.

The present invention has been made to solve the above-mentioned conventional technical problem, and supplies ice and water into a container such as a glass, and suppresses water splash from the container due to falling of ice. It is an object of the present invention to provide an ice / water supply device capable of preventing the ice / water supply. Another object of the present invention is

When the timer 42 is opened, the timer 42 is in the continuous carry-out mode.

Returning to FIG. 1, the auger motor 4 is connected to the common terminal of the switching contact 46A of the relay coil 46, and the normally closed a terminal of the switching contact 46A is connected via another normally open contact 33B of the relay coil 33. The switching contact 48A of the relay coil 48 is connected to the normally closed terminal a. The normally open b terminal of the switching contact 46A is connected between the carry-out switch 31 and the carry-out timer device 36, and the solenoid 13 is connected to the normally open b terminal of the switching contact 48A. A series circuit of a normally closed contact 51A of a relay coil 51 and a water extraction solenoid valve 25 is further connected between the carry-out switch 31 and the carry-out timer device 36, and an ice storage switch 7 and a water cutoff switch are connected to the relay coil 33. 8 are connected in series. Further, a water level switch 10 is connected in series to the ice making water supply electromagnetic valve 6.

The operation of the ice / water supply apparatus I of the present invention will be described with reference to the timing charts of FIGS. First, the ice making operation of the ice making device A will be described. When the water storage tank is empty, the water level switch 10 is closed, the water supply electromagnetic valve 6 for ice making is energized and opened, and water is supplied from the water supply pipe 9 to the water storage tank. Then, when the inside of the water storage tank rises to a predetermined water break level, the water break level switch 8 closes,
Further, when the water level rises to the ice making water level, the water level switch 10 is opened, the power supply to the ice making water supply solenoid valve 6 is cut off, and the water supply is stopped. When a predetermined amount of ice 19 is not stored in the ice storage container 5, the ice storage switch 7 is closed, thereby energizing the relay coil 33 to close the contact 33A and energizing the compressor 3 and the fan 32. Therefore, the evaporator 1 is cooled and ice making is started on the inner surface of the cylinder. Furthermore, contact 3
3B is also closed, the auger motor 4 is energized via the a terminal of the switching contact 48A and the a terminal of the switching contact 46A, and the ice making operation is started as described above, and the generated chip-like ice 19 is stored in the ice storage container 5. Going to be stored.

When the ice 19 in the ice storage container 5 reaches a predetermined amount, the ice storage switch 7 is opened and the relay coil 33 is de-energized, so that the contacts 33A and 33B are opened, and the compressor 3, the fan 32 and the auger motor 4 stops and shifts to the ice storage process. In this state, the mode switch 41
Is closed, and the timer time setting circuit 38 of the carry-out timer device 36 is closed.
The operation of supplying ice and water will be described with reference to FIG. When the user presses the carry-out lever 16 from the front as shown in FIG.
The carry-out switch 31 is closed (ON). As a result, the carry-out command section 37 outputs a carry-out command signal,
3 and 44 conduct the transistors 47, 49 and 52 to energize the relay coils 46, 48 and 51,
Invert 6A, 48A and 51A. As a result, the auger motor 4 is energized (ON) through the b contact of the switching contact 46A and the carry-out switch 31, and the agitator 28 rotates to send out the ice 19 in the ice storage container 5 to the ice carry-out port 11. In addition, the solenoid 13 is energized (ON) via the b terminal of the switching contact 48A, and the shutter 12 is opened.
The fed ice 19 passes through the chutes 14 and 15 and first starts being carried out into the glass 18.

The ice discharge is continued until the discharge time T1 determined by the timer time setting circuit 38 elapses. When a predetermined amount of ice 19 is supplied into the glass 18 and the discharge time T1 has elapsed, the timer 42 is reset. When the time is up and the signal is received, the timer 44 causes the transistors 47 and 52 to
Is turned off, the relay coils 46 and 51 are turned off, and the contacts 46A and 51A are inverted. As a result, the power to the auger motor 4 is cut off (OFF), and the agitator 2 is turned off.
The discharge of the ice 19 to the ice discharge port 11 by the ice 8 is stopped.
Further, when the carry-out switch 31 is closed, the water extraction solenoid valve 25 is simultaneously energized (ON) and opened.
Water supply into the cup 18 from the water outlet 21 is started. That is, since the water is supplied after the ice carry-out is stopped, it is possible to prevent the water from jumping from the glass caused by the falling of the ice into the water in the glass 18.

On the other hand, the timer 43 keeps the transistor 49 conductive for T2, which is several seconds longer than the time at which the time-up signal is output from the timer 42, and turns off the relay coil 48 after the lapse of T2. cut off. As a result, the switching contact 48A is reversed, the solenoid 13 is de-energized (OFF), and the shutter 12 is moved to the ice exit 11
Close. That is, after stopping the delivery of ice by the agitator 28, after a delay time DT of several seconds, the shutter 1
2 closes the ice outlet 11, so that ice 19, which is sandwiched between the shutter 12 and the ice outlet 11, that is, the so-called ice biting can be reliably prevented.

Thereafter, when the water in the cup 18 reaches a predetermined water level and the user releases the cup 18 from the carry-out lever 16, the carry-out switch 31 is opened, so that the power supply to the carry-out timer device 36 is cut off, and each contact is in the initial state. And the power supply to the water extraction solenoid valve 25 is also cut off (OFF), so that the water supply from the water outlet 21 is also stopped. If the cup 18 is released from the unloading lever 16 during the unloading of the ice,
Since the power supply to the carry-out timer device 36 is cut off, the agitator 28 is stopped, and the shutter 12 is immediately moved to the ice carry-out port 11.
And all operations are stopped.

Next, the mode switch 41 is opened, and
The operation of supplying ice and water when the timer 38 of the unloading timer device 36 is in the continuous unloading mode will be described with reference to FIG. The user similarly operates the carry-out switch 1 with the cup 18.
When the button 6 is pressed from the front, the carry-out switch 31 is closed (ON), so that the carry-out command section 37 outputs a carry-out command signal, and the timers 42, 43, and 44 control the transistors 47, 49.
And 52 are turned on to make the relay coils 46, 48 and 51 conductive.
And the contacts 46A, 48A and 51A are inverted. Accordingly, the auger motor 4 is similarly energized via the b contact of the switching contact 46A and the carry-out switch 31 (O
N), the agitator 28 rotates and the ice 19 in the ice storage container 5
To the ice outlet 11. In addition, b of the switching contact 48A
Electric power is supplied to the solenoid 13 via the terminal (ON), and the shutter 12 is opened, so that the sent ice 19 passes through the chutes 14 and 15 and starts being carried into the cup 18.

When a predetermined time T3 has elapsed from the generation of the carry-out command signal, the timer 44 turns off the transistor 52, so that the relay coil 51 is turned off and the contact 51A is inverted. Therefore, when the carry-out switch 31 is closed, the water extraction solenoid valve 25 is energized (O
N) Then, since the water is opened, water supply from the water outlet 21 into the cup 18 is started. That is, since water supply is started after the ice 19 has been carried out to the glass 18 to some extent, carrying out of the ice 19 is prioritized. Therefore, even when a large amount of water is discharged, it is possible to eliminate the occurrence of the ice shortage as in the related art. it can. Also, by appropriately setting the delay time T3 from the removal of ice to the start of water supply, the proportion of the amount of ice 19 and water in the cup 18 can be arbitrarily selected. Furthermore, since only the ice 19 is initially carried out, it is possible to suppress the splash of water from the glass caused by the ice falling into the water in the glass 18.

Thereafter, when the water in the cup 18 reaches a predetermined water level and the user releases the cup 18 from the carry-out lever 16, the carry-out switch 31 is opened, so that the power supply to the carry-out timer device 36 is cut off, and each contact is in the initial state. And the power supply to the water extraction solenoid valve 25 is also cut off (OFF), so that the water supply from the water outlet 21 is also stopped. As a result, the relay coils 46 and 48 are de-energized, and the contacts 46A and 48
Since A is reversed, the power supply to the auger motor 4 is cut off (OFF), the discharge of the ice 19 to the ice discharge port 11 by the agitator 28 is stopped, and at the same time, the solenoid 13 is de-energized (OFF) to release the shutter. 12 is the ice exit 11
Close. That is, in the continuous unloading mode, the unloading of the ice 19 is continued until the cup 18 is released from the unloading lever 16. Therefore, when the agitator 28 stops, the cup 18 does not exist below the chute 15. If the shutter 12 is closed with a delay in such a state, the amount of the ice 19 spilling out of the ice discharge port 11 increases, but in the present invention, the delay time DT is eliminated in the continuous discharge mode, and the stop of the agitator 28 is stopped. At the same time, since the shutter 12 is closed, the spilling and falling of the ice 19 can be suppressed or prevented.

If the shutter 12 is closed without delay from the stop of the agitator 28 as described above, there is a danger that ice will be generated at the ice outlet 11; By closing the shutter 12 with a delay time shorter than the delay time DT, it is possible to prevent ice 19 from spilling and to prevent the ice 19 from falling off.

[0030]

As described above in detail, according to the first aspect of the present invention, a predetermined amount of ice is carried out into the container by pressing the carry-out lever with a container such as a cup, and after the ice carrying-out is completed. Since water is supplied until the container is released from the carry-out lever, a predetermined amount of ice water can be easily stored in the container. In particular, since water is supplied after a predetermined amount of ice has been carried out first, the occurrence of ice shortage can be reliably prevented, and water supply will be started after ice has been carried out, so that ice may fall into the water. This can eliminate water splashing from the container.

According to the second aspect of the present invention, the ice is first carried out into the container by pressing the carry-out lever with a container such as a glass, and after a lapse of a predetermined time from the start of carrying out the ice, the water is discharged. Is supplied and water is supplied until the container is released from the carry-out lever, so that ice water can be easily stored in the container. In particular, since water is supplied late from the removal of ice, ice is supplied in preference to water,
Since the shortage of ice can be solved, and water is discharged after the ice has been carried out to some extent, it is possible to suppress water splashing from the container due to the falling of ice into the water.

Further, according to the third aspect of the present invention, the user can arbitrarily select between a fixed quantity carrying mode in which a predetermined amount of ice is carried out and a continuous carrying mode in which ice is carried out while the carrying lever is pressed. Therefore, in addition to being highly convenient, the shutter is closed after the ice discharging member is stopped in the constant-rate discharging mode, so that ice can be prevented from being caught between the shutter and the ice discharging port. In the continuous discharge mode, the shutter close delay time was shortened, or the shutter was closed simultaneously with the stop of the ice discharging member.Therefore, the amount of ice spilling out of the ice discharge port after the container such as a cup was separated from the discharge lever. And the spilling of ice can be prevented.
