Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric liquid discharging apparatus such as an electric pot for discharging liquid in a container to the outside by an electric pump.

[0002]

Generally, as an electric liquid discharging apparatus of this kind, in an electric pot which uses an electric pump to supply hot water, drive power is supplied to the electric pump only while operating a hot water switch as an operating means. Thus, a tapping operation of discharging the hot water in the container to the outside is performed. However, in this case, there were the following problems.

When pouring hot water for a long time, such as when pouring water into a pot or the like, it is necessary to keep pressing the hot water switch during that time, and it is painful and inconvenient for the user to keep pressing the hot water switch. Also, when pouring the same amount of hot water into a coffee cup, etc., the user must press the tap switch until the cup is full and repeat this operation many times, which is inconvenient for the user. Was.

[0004] In order to cope with such a problem, there has been known a device which supplies a drive power to an electric pump for a preset time and automatically discharges hot water when a hot water switch is operated. However, hot water is discharged every time for a certain period of time,
Moreover, since this time is set regardless of the time desired by the user, it is actually inconvenient because it is longer or shorter than the desired ejection time. In addition, the weight sensor measures the amount of liquid in the container or the liquid discharged to the outside, or the flow rate sensor measures the change in the amount of liquid during discharge, and automatically sets the set amount of liquid. However, the provision of such a weight sensor or flow rate sensor itself has led to an increase in the size of a system (product), complicated control, and increased costs. .

The present invention has been made to solve the above-mentioned problem, and has a simple structure without a sensor, and discharges a desired amount of liquid every time by simply performing a liquid discharge operation. It is an object of the present invention to provide a motor-operated liquid ejection device capable of performing the above-described operations.

[0006]

In order to achieve the above object, the present invention provides an electric liquid discharging apparatus, comprising: a container for accommodating a liquid; an electric pump for discharging the liquid in the container to the outside;
A pump power supply for driving the electric pump, operating means for operating a liquid discharging operation, operating means detecting means for monitoring whether the operating means is operated, and energizing the electric power to the electric pump. Pump current control means for controlling, time-measuring means for measuring time when the operation means detecting means detects that the operating means is being operated, and storage means for storing the time measured by the time-measuring means,
When the operating unit is operated for the first time, the electric pump is operated with the pump energizing control unit in the energized state, and the time during which the operating unit is operated is measured, and the time is stored at the end of the operation. When the operating means is operated from the next time on, the control means performs continuous discharge with the pump energizing control means being in an energized state for a time stored in the storage means.

In this case, when the operating means is operated for the first time, the time for operating the operating means is counted by the time measuring means, and when the operation is completed, it is stored in the storage means. Next, when the operating means is operated, the pump energizing control means is energized this time for the time stored in the storage means, and the electric power is supplied from the pump power supply to the electric pump to perform continuous discharge. In other words, the user can automatically discharge the desired amount of liquid by first operating the operating means for a time corresponding to the desired liquid discharge amount, without having to continue operating the operating means thereafter. This is convenient when pouring the liquid for a long time, such as when pouring hot water into a pot or the like.
Further, the same amount of liquid can be continuously and easily discharged every time only by operating the operation means without providing a dedicated sensor as in the related art. Further, by changing the operation time of the first operation means, the user can arbitrarily set a favorite or necessary liquid ejection amount, so that dissatisfaction of a device that can discharge only the same amount of liquid determined each time can be solved, This is useful for pouring many cups of the same amount of liquid, such as coffee or tea. Further, since a dedicated sensor is not provided, complicated devices and controls are not required, and a system and a circuit configuration inside the device are simplified, and an increase in cost can be suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the electric liquid ejection apparatus of the present invention will be described with reference to the accompanying drawings.
The electric liquid discharging apparatus according to the present embodiment is an electric pot that discharges hot water stored in a container (not shown) to the outside. In the block diagrams of FIGS. 1 and 2, reference numeral 1 denotes control means for controlling the operation of the whole electric pot. The control means 1 is constituted by, for example, a microcomputer. Reference numeral 2 denotes an electric pump for discharging hot water heated in a container by a heating means (not shown) to the outside. A pump power supply 3 for outputting a voltage or a current necessary for driving the electric pump 2 includes: It is connected to the electric pump 2 via the first pump driving means 4 and the second pump driving means 5. The first pump driving means 4 and the second pump driving means 5 correspond to a pump power control means 6 for controlling the power supply from the pump power supply 3 to the electric pump 2.

Reference numeral 11 denotes operating means for controlling the discharge operation of hot water as a liquid. In this embodiment, as shown in FIG. 2, a common terminal COM is always connected to one end, and a normally open terminal NO or a normally closed terminal is connected. The hot water outlet switch 12 is composed of a microswitch having a movable contact 12A for connecting the other end to one of the contacts NC. This hot water switch 12 not only supplies or shuts off the drive power from the pump power supply 3 to the electric pump 2,
It also has the function of operating means detecting means 13 for monitoring the operating position of operating means 11. Reference numeral 14 denotes time counting means for counting the time when the tapping switch 12 is pressed based on the monitoring signal from the operating means detecting means 13. Is recognized, the time measured by the time measuring means 14 is stored in the storage means 15. Reference numeral 16 denotes a notification lamp (not shown) for notifying operations such as water heating and heat retention, in addition to a continuous display lamp 17 for displaying that it is a continuous hot water supply.
The display means comprises:

[0010] As shown in FIG.
Connects one end of the pump power supply 3 to the common terminal COM, connects the normally closed terminal NC to the input port PI1 of the control means 1, and connects the normally open terminal NO to the PNP constituting the first pump driving means 4. It is connected to the emitter of the type transistor 31. The collector of the transistor 31 is connected to one end of the electric pump 2, and the other end of the electric pump 2 is connected to a pump power supply 3.
To form a closed circuit from pump power supply 3 → water tap switch 12 → transistor 31 → electric pump 2 → pump power supply 3. The monitoring signal line of the operating means detecting means 13 from the normally closed terminal NC of the tapping switch 12 to the input port PI1 of the control means 1 is grounded via a resistor 21. Thus, when the tap switch 12 is pressed, the movable contact 12A is connected to the normally open terminal NO side, and the operating means detecting means 13
Is at the L (low) level, which is the same potential as the ground line, and the transistor 31 of the first pump driving means 4
Only when is ON, the driving power from the pump power supply 3 is supplied to the electric pump 2 from the hot water switch 12 via the transistor 31. When the finger is released from the tap switch 12, the movable contact 12A self-recovers and connects to the normally closed terminal NC, and the monitoring signal of the operating means detecting means 13 is H (H) having the same potential as the driving power from the pump power supply 3. High) level, the supply of drive power from the pump power supply 3 to the electric pump 2 is cut off.

The first pump driving means 4 operates at an operating voltage VC.
Voltage dividing resistors 32 and 33 are connected in series between the terminal and the output port PO1 of the control means 1, and the connection point of the resistors 32 and 33 is connected to the base of the transistor 31.
When the tap switch 12 is pressed for the first time, the output port PO1 of the control means 1 is switched from the H level to the L level only while the tap switch 12 is pressed, and the transistor 31 is turned on, that is, the pump energization control means. 6 is energized, and the drive power from the pump power supply 3 is supplied to the electric pump 2. At the same time, the control means 1 starts time measurement by the time measurement means 14. After that, when the finger is released from the hot water switch 12 and the operation of the operation means 11 is completed,
The time measured by the timer 14 is stored in the storage 15.

The second pump driving means 5 includes a pump power supply 3
Is connected to one end of the PNP transistor 41,
The collector of the transistor 41 is connected to one end of the electric pump 2, and resistors 42 and 43 for voltage division are connected in series between the operating voltage VC terminal and the output port PO2 of the control means 1. The transistor 41 is connected to the connection point 43.
The base is connected. As a result, another closed circuit from the pump power supply 3 → the transistor 41 → the electric pump 2 → the pump power supply 3 is formed. Then, when the tap switch 12 is pressed after the second time, the time during which the tap switch 12 is pressed for the first time is read out from the storage means 15, and the output port PO2 of the control means 1 is changed from the H level to the L level for this time. By switching, the drive power from the pump power supply 3 is supplied to the electric pump 2.

Next, the operation of the above configuration will be described with reference to the flowchart of FIG. 3 and the waveform diagram of FIG. FIG. 4 shows the operation timing of each part when the tap switch 12 is operated. The top row shows the operation time of the tap switch 12, and the tap switch 12, the transistor 31, the transistor 41, and the Each operation of the pump 2 and tapping is shown.

In the flow chart of FIG. 3, while the tap switch 12 is off (step S1), the output ports PO1 and PO2 of the control means 1 are at the H level.
Transistor 31 forming first pump driving means 4 and transistor 41 forming second pump driving means 5
Are both turned off. Therefore, the power supply from the pump power supply 3 to the electric pump 2 is cut off, and the operation of the electric pump 2 and, consequently, the tapping operation is also turned off. At this time, the display means 16
Is turned off, that is, turned off (step S2).

In step 3, the tap switch 12 is depressed, and the contact of the movable contact 12A is switched from the normally closed terminal NC side to the normally open terminal NO side. When the control unit 1 recognizes the ON state of the tapping switch 12, the control unit 1 determines whether the tapping switch 12 has been operated for the first time (step S4). This determination is made based on whether or not the time during which the tap switch 12 has been pressed has already been stored in the storage means 15. If the time during which the tapping switch 12 has been pressed is not stored in the storage means 15, it is determined that the tapping switch 12 has been operated for the first time, and the process proceeds to step S5. This step S5
Then, the timer (time) of the clock means 14 is cleared, and in the next step S6, the output port PO1
Is switched to the L level, the transistor 31 constituting the first pump driving means 4 is turned on, and the driving power from the pump power supply 3 is supplied from the hot water switch 12 to the electric pump 2 via the transistor 31. Thereby, the electric pump 2 operates and the operation of tapping water starts. At the same time, the timer 14 also starts counting by the timer (step S
7). Hot water tapping operation in step S6 and step S7
The count of the timer of the timer means 14 is continued unless the finger is released from the hot water switch 12 and turned off (step S8).

In step S8, operation means detecting means
When the control means 1 recognizes that the finger has been released from the tapping switch 12 based on the monitoring signal of 13, the count time of the clocking means 14 that was counting while the tapping switch 12 was being pressed is stored in the storage means 15 ( Step S9). Further, the control means 1 switches the output port PO1 to the H level, turns off both the transistors 31 and 41, stops the supply of drive power from the pump power supply 3 to the electric pump 2, and turns off or ends the tapping operation. (Step S10). Then, the procedure returns to the procedure of step S1 described above.

On the other hand, in step S4, if the time during which the tapping switch 12 has been pressed has already been stored in the storage means 15, the control means 1 executes the tapping switch after the second time.
It is determined that the user has operated No. 12, and the procedure moves to the procedure after step S11. In step S11, it is determined based on the monitoring signal from the operating means detecting means 13 whether or not the tap switch 12 has been pressed for a predetermined time, for example, one second or more. Here, if the time during which the tapping switch 12 is pressed is shorter than 1 second, the tapping operation is stopped immediately after the finger is released from the tapping switch 12 without the continuous tapping operation corresponding to the continuous discharge operation described later. Then, the procedure returns to the procedure of step S1 described above. On the other hand, in step S11, when the tapping switch 12 is kept pressed for 1 second or longer, the procedure shifts to the procedure of the continuous tapping operation after step S12.

More specifically, in step S12, the timer (time) of the time counting means 14 is cleared, and in the next step S13, the control means 1 sets the output port P
O2 is switched to L level. Thereby, the transistor 41 constituting the second pump driving means 5 is turned on, and the driving power from the pump power supply 3 is supplied to the electric pump 2 via the transistor 41. Step S1
In 4, the continuous hot-water lamp 17 of the display means 16 is turned on, and in step S15, the timer of the timer means 14 starts counting. The tapping operation in step S13, the lighting of the continuous tapping lamp 17 in step S14, and the count of the timer of the timer 14 in step S15 are performed until the time when the tap switch 12 is pressed for the first time stored in the storage unit 15. , Regardless of the operation of the tap switch 12. That is, if the tapping switch 12 is kept pressed for at least one second after the second time, the same amount of continuous discharge as when the tapping switch 12 is pressed the first time is performed.
Thereafter, in step S16, when the time stored in the storage means 15 has elapsed, the control means 1 outputs the output port PO2
Is switched to the H level, the transistors 31 and 41 are both turned off, the supply of drive power from the pump power supply 3 to the electric pump 2 is stopped, and the tapping operation is turned off, ie, terminated (step S17). Further, the continuous tapping lamp 17 of the display means 16
Is also turned off, that is, turned off (step S18). And
The procedure returns to step S1.

In this series of operations, the operation timing of each unit is as shown in FIG. When the tap switch 12 is turned on by pressing the hot water switch 12 for the first time, the output port PO1 of the control means 1 is switched from H level to L level, and the transistor 31 constituting the first pump driving means 4 is turned on, and the electric pump is turned on. 2 works. At this time, the output port PO2 of the control means 1 remains at the L level, and the transistor 41 constituting the second pump driving means 5 is off. Then, when the finger is released from the tapping switch 12 after the tapping switch 12 is continuously pressed for 10 seconds, for example, the power supply from the pump power supply 3 to the electric pump 2 is cut off and the output port of the control means 1 is turned off. PO1 switches from the L level to the H level, and the transistor 31 is also turned off. That is, in this case, a normal tapping operation in which the electric pump 2 is turned on only while the tapping switch 12 is pressed is performed.
The time (10 seconds) when the hot water switch 12 was pressed is measured
This time is counted by 14, and at the same time when the tapping switch 12 is turned off, this time is stored in the storage means 15.

When the tap switch 12 is pressed after the second time, if the tap switch 12 is kept pressed for one second or longer, a continuous tapping operation is performed. In this case, when the tap switch 12 is pressed for one second or longer, the output ports PO1 and PO2 of the control means 1 store the time (10 seconds) stored in the storage means 15 even if the finger is released from the tap switch 12 thereafter. With the level maintained, the transistors 31 and 41 remain on, and the operation of the electric pump 2 continues. Then, when 10 seconds, which is the time stored in the storage means 15, has elapsed, the transistors 31 and 41 are both turned off, and the pump power supply 3
Then, the supply of the drive power to the electric pump 2 is shut off, and the tapping operation is stopped. When the tap switch 12 is pressed again for one second or more, the continuous tapping operation is performed for 10 seconds. However, within one second after pressing the tap switch 12 (for example, 0.
When the finger is released at 5 seconds), the transistors 31 and 41 are both turned off at that point, and the tapping operation is immediately stopped without the continuous tapping operation.

Further, after the tap switch 12 is pressed for one second or more after the second time, once the finger is released from the tap switch 12 and the tap switch 12 is pressed again during continuous tapping (for 10 seconds), at that time, Transistors 31 and 41 are both turned off,
The operation of the electric pump 2 is stopped, and the continuous tapping operation is stopped halfway. In this way, the continuous tapping operation can be stopped halfway by the single tapping switch 12. Until the continuous tapping operation is stopped, if the tapping switch 12 is first pressed and turned on for at least one second, the continuous tapping operation for 10 seconds is repeated.

As described above, in the present embodiment, the electric pump 2 for discharging the liquid to the outside, the pump power supply 3 for driving the electric pump 2, the operating means 11 for operating the liquid discharging operation, An operating means detecting means 13 for monitoring whether or not the operating means 11 is operated; a pump energizing control means 6 for controlling energization of a drive power supply to the electric pump 2;
Is operated, the operation means detection means 13 detects the time when the operation means detection means 13 is time, the storage means 15 for storing the time measured by the time measurement means 14, the first time the operation means 11 When operated, the electric pump 2 is operated while the pump energization control means 6 is energized, and
The time during which the operation means 11 is operated is measured, and the time is stored in the storage means 15 at the end of the operation, and when the operation means 11 is operated after the next time, the pump energization control is performed for the time stored in the storage means 15. And control means 1 for performing continuous discharge with the means 6 in an energized state.

In this case, when the operating means 11 is operated for the first time, the time during which the operating means 11 is operated is timed by the time measuring means 14, and when the operation is completed, it is stored in the storage means 15.
Next, when the operating means 11 is operated, the pump energizing control means 6 is energized only for the time stored in the storage means 15 and the driving power is supplied from the pump power supply 3 to the electric pump 2 to perform continuous discharge. In other words, if the user continues to operate the operating means 11 for a time commensurate with the desired liquid discharge amount at the beginning, the user automatically discharges the desired amount of liquid without continuing to operate the operating means 11 in the same manner thereafter. Can be
This is particularly useful when pouring the liquid for a long time, such as when pouring hot water into a pot or the like. Further, the same amount of liquid can be continuously and easily discharged every time only by operating the operation unit 11 without providing a dedicated sensor as in the related art. Furthermore, by changing the operation time of the first operation means 11,
The user can arbitrarily set the desired or required liquid discharge amount, eliminating the dissatisfaction of the device that can discharge only the same amount of liquid determined each time, and pouring the same amount of liquid such as coffee or tea It is convenient. Further, since a dedicated sensor is not provided, complicated devices and controls are not required, and a system and a circuit configuration inside the device are simplified, and an increase in cost can be suppressed.

Other examples of the modification of this embodiment are listed below.
In the present embodiment, the electric pot for heating the hot water in the container by the heating means has been described. However, the present invention can be applied to any electric liquid ejecting apparatus having no heating means. Further, the setting of each time shown in FIG. 4 may be changed as appropriate.

The circuit configuration of the pump energization control means 6 is shown in FIG.
As shown in the figure, the collector of the transistor 41 constituting the second pump driving means 5 is connected to the normally open terminal NO of the hot water switch 12.
To the emitter of the transistor 31. In this case, the control unit 1 is operated in the second and subsequent operations.
The drive power is supplied from the pump power supply 3 to the electric pump 2 only when each of the output ports PO1 and PO2 becomes L level. Further, if the operating means 11 and the pump energization control means 6 are made circuit independent, and the pump energization control means 6 is constituted by a single pump driving means, the circuit can be further simplified.

Although the tap switch 12 of this embodiment uses the single movable contact 12A for both the operating means 11 and the operating means detecting means 13, the functions are independent by a pair of interlocking open / close contacts. Or a plurality of contacts may be provided. A large number of tap switches 12 and first and second pump driving means 4 and 5 constituting the operating means 11 may be provided.

In the present embodiment, the first operation for setting the liquid discharge amount and the second and subsequent operations for continuously discharging the same amount are performed by the tap switch 12, which is a common switch means. The configuration of the switch unit is simplified. However, the operations related to the second and subsequent consecutive ejection operations
It may be performed by a dedicated switch means different from the hot water switch 12. In this way, the user can easily distinguish which switch means should be used for setting the liquid discharge amount and performing the continuous discharge operation, and confusion during the operation hardly occurs.

In this embodiment, the pump energization control means 6
The control means 1 is configured so that, when the operation means 11 is operated again while the continuous discharge is being performed with the power supply being in the energized state, the continuous discharge is stopped halfway. Thereby, for example, when the liquid is likely to overflow from the container during the continuous discharging operation, the liquid discharge can be stopped halfway by simply operating the operating means 11 again, and the problem that the liquid is discharged more than necessary can be prevented. Can be eliminated. In this case, the switch for stopping the continuous discharge in the middle is also performed by a dedicated switch (for example, a stop switch) different from the hot water switch 12 of the operation unit 11 so that the user can easily understand the operation immediately. May be.

Alternatively, the continuous discharge time may be limited so that the continuous discharge is stopped after a predetermined time has elapsed. In this way, it is possible to prevent the liquid from being ejected for a long time when the continuous ejection operation is mistakenly performed.
Further, a configuration may be adopted in which the time stored in the storage unit 15 is limited.

As in the present embodiment, when the continuous discharge operation is not performed for a predetermined time or more, the continuous discharge operation may be canceled. In this case, the data of the time stored in the storage means 15 may be deleted, or the display means 16 may be switched to a display other than the continuous ejection operation. In this case, there is an advantage that an unintended continuous discharge operation is not performed even when the user forgets to set the continuous discharge operation and performs the operation again or when another person who does not understand the continuous discharge operation uses the continuous discharge operation. .

In the present embodiment, the hot water switch 12
The control means 1 may be configured so that if the user continues to operate for a predetermined time or more, the time stored in the storage means 15 can be reset. For example, when the time of the continuous discharge operation is set and the tapping switch 12 is pressed for one second after the second time, the continuous discharge operation is performed according to the time stored in the storage means 15, while the tapping switch 12 is pressed for three seconds or more. In such a case, the continuous discharge time stored in the storage means 15 can be reset according to the time during which the tap switch 12 is pressed. In this case, if the time of the continuous discharge operation is set to 10 seconds and the tapping switch 12 is pressed, for example, for 5 seconds, the time of the continuous discharge operation is reset to 5 seconds. In this case, the time of the continuous discharge operation can be easily changed only by operating the operation means 11, and the usability is improved.

Further, the duration of the continuous discharge operation may be set only when the operation means 11 has been operated for a predetermined time or more. For example, if the time of the continuous discharge operation is set when the tapping switch 12 is kept pressed for 5 seconds or more, there is an advantage that the continuous tapping operation is not erroneously set.

In this embodiment, a switching means for switching whether or not to perform the continuous discharge operation may be separately provided. With this configuration, the actual continuous discharge operation is performed only when the setting is made to perform the continuous discharge operation by the switching unit, and the usability is improved.

The time stored in the storage means 15 may be the operating time of the electric pump 2 instead of the time during which the tapping switch 12 is pressed.

In this embodiment, a backup means may be provided for retaining the data stored in the storage means 15 even if a power failure occurs, so that a continuous ejection operation for the same time as before the power failure after recovery from the power failure may be performed. Thus, even if there is a power failure, it is not necessary to reset the time of the continuous ejection operation. Further, if the electric pump 2 can be driven even during a power failure by this backup means, liquid can be discharged even during a power failure. If a non-volatile storage element such as an external storage means such as an EEPROM is used as the backup means, the data in the storage means 15 can be retained even if a power failure occurs, and the continuous ejection operation can be performed for the same time after the power failure recovery as before the power failure. Will be possible.

The conditions for resetting the continuous discharge operation include, as described above, a case where the continuous discharge operation is not performed for a predetermined time or more, and a case where the tapping switch 12 of the operating means 11 is continuously operated for a predetermined time or more. Alternatively, for example, a cancel switch may be provided, and when the cancel switch is pressed, the operation may be returned to the first operation of the operation unit 11.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made.
