[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic tea supply device capable of supplying tea to both large-capacity and small-capacity tea-receiving containers, and particularly by detecting the position of the stage on which the small-capacity tea-receiving container is placed. The present invention relates to an automatic tea supply device capable of performing only a tea supply operation suitable for the type of tea receiving container to be supplied with tea.

[0002]

[Prior art]

 Conventionally, various tea supply devices have been proposed.In these tea supply devices, a predetermined amount of tea leaves stored in a tea leaf storage tank are supplied to a tea filter, and hot water poured out from a water supply nozzle is used for the tea filter. After passing, it becomes tea water and is usually supplied to a tea-receiving container such as a teacup placed at the tea supply position. In such a tea supply device, supply of tea leaves to the tea filter, recovery of exhausted tea leaves used in the tea filter, placement of a tea-receiving container such as a teacup or pot at the tea-supplying position, and tea water from the tea-receiving container In many cases, various ideas have been devised from the viewpoint of preventing droplets from adhering to the inside of the aircraft. For example, Japanese Patent Application No. 3-109258 discloses a device capable of supplying tea to both a large tea container such as a pot and a small tea container such as a teacup with one automatic tea supply device. ing.

That is, in the same invention, the tea supply unit is formed large so that a pot or the like can be stored, and a retractable slide arm is provided on the back plate of the tea supply unit to slide the pot or the like. On the other hand, the arm is retracted. On the other hand, when placing a cup, etc., the slide arm is pulled out and the cup is placed on the cup stage formed on the slide arm. As a result, it is possible to supply tea directly from the tea supply device to the pot, etc., and prevent complicated transfer work and lowering of the hot water temperature. Further, in the tea supply device of the same invention, two water supply nozzles are provided, and by selectively using them depending on the tea-receiving container to be supplied with tea, quick tea supply to a pot or the like is possible. Here, the type of tea-receiving container to be supplied with tea is identified by the position of the slide arm. Furthermore, separate tea supply command switches for pots and teacups are provided, and the pouring time for each tea supply can be changed according to the type of tea-receiving container to be supplied with tea. Together, they are able to provide an appropriate amount of tea. This makes it possible to easily supply tea to pots and the like, and has realized an automatic tea supply device that does not stain the tea supply part due to splashes when tea is normally supplied to teacups.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional tea supply device has the following problems. That is, the slide arm and the tea supply command switch are independent of each other, the position of the slide arm determines the water supply nozzle for supplying tea, and the tea supply command switch determines the pouring time of the tea water. Therefore, even when the slide arm is pulled out and tea is supplied to the teacup, if the tea supply switch for the pot is accidentally pressed, tea is supplied according to the pouring time for the pot. At this time, the pouring tea water overflows from the teacup and flows out around the tea supply section. Therefore, there is a possibility that the operator's hand is exposed to tea water and burns. Further, the tea water that flows out is scattered around the tea supply device, which may cause a failure of the tea supply device or lead to a hygienic unfavorable state. On the other hand, even if the slide arm is retracted and tea is supplied to the pot, if the tea supply switch for the teacup is accidentally pressed, tea is supplied according to the time for which the teapot is poured, so the amount dispensed is insufficient. . After that, when the operator noticed this and pressed the tea supply switch for the pot again, the total amount of pouring out became excessive, so the tea water overflowed from the pot due to the capacity overrun.

Further, even if the slide arm is moved for some reason during tea supply, the tea supply is not stopped depending on the movement. For example, when the slide arm is pulled out while tea is being supplied to the pot, one of the two water supply nozzles that are supplying water is stopped, while the other continues supplying water. Also, if the slides arm is retracted while tea is being supplied to the teacup, the water supply nozzle that is supplying water continues to supply water. In such a case, the tea-receiving container is often removed or not in the correct position, so the tea pouring that continues to be poured out flows out around the tea-supplying part, etc., and reaches the same state as above. It was The present invention has been made to solve the above-mentioned problems of the prior art. The operator determines the number of water supply nozzles for pouring tea water and the pouring time by the position of the sliding arm. It is an object of the present invention to provide a clean automatic tea supply device that improves the safety and usability of the product, eliminates the possibility of breakdown, and improves hygiene.

Further, a tea leaf supply port 26 is opened downward from the tea leaf quantification unit 25. Here, the tea leaf quantification unit 25 is rotatably driven by a drive motor (not shown) and supplies tea leaves stored in the tea leaf storage tank 24 to the tea filter 27 through the tea leaf supply port 26 in a fixed amount. At the rear of the tea leaf storage tank 24, a guide plate 28 having a rail portion 28A formed at the bottom is arranged, and the guide plate 28 is provided with a tea filter drive device 29 driven by the drive motor. The tea filter support 30 is guided along the rail portion 28A in the left and right directions in FIG. A tea filter 27 is rotatably supported on the tea filter supporter 30 via a rotating pin 31, and the tea filter 27 is at a tea leaf exchange position on the left side of the tea supply position shown in FIG. The used tea leaves are rotated counterclockwise around the rotation pin 31 via the drive motor to discharge the used tea leaves into the tea leaf discharge container 32. Inside the tea leaf discharge container 32, a plastic bag molded from polyethylene or the like is attached, and when a certain amount of used tea leaves is accumulated in the plastic bag, it is formed on the side wall of the tea leaf discharge container 32. The tea leaf discharge container 32 is taken out of the tea supply device 1 by grasping the handle portion 32A, and used tea leaves are discarded.

Two water supply nozzles 33 and 34 are provided above the tea filter 27, and water supply valves 35 and 36 are provided above the water supply nozzles 33 and 34, respectively. Hot water is supplied to the water supply nozzles 33, 34 from a hot water tank 37 installed at the rear through a hose (not shown). The opening and closing of each of the water supply valves 35 and 36 is controlled by a control device which will be described later, and for a small tea container such as a teacup Q, only one water supply valve 35 is opened for a short time (for example, about 4 seconds). Further, for a large tea container such as the pot P, both water supply valves 35 and 36 are opened for a long time (for example, about 12 seconds). Further, a flowing water receiving tray 38 is disposed below the tea filter 27, and the flowing water receiving tray 38 is formed in a funnel shape, and the tea extracted from the tea filter 27 is attached to the lower portion. The tea is supplied from the tea nozzle 22 to the pot P or the like.

Above the water supply nozzles 33 and 34, an exhaust cylinder F having a large open bottom is provided, and the hot water is supplied from the water supply valves 33 and 34 through an exhaust fan that is driven to rotate by a fan motor. The steam generated when the tea is supplied to the tea filter 27 is exhausted to the outside of the tea supply device 1.

Further, an opening 20A is formed in the back wall plate 20 which constitutes a part of the tea supply part 21 described above, and the cup 20 and the like which can be moved forward and backward are placed through the opening 20A. A drinking cup stage 39 (see FIG. 2) is provided. Such a teacup stage 39 is moved backward so as not to disturb tea supply when tea is supplied to the pot P, while it is pulled out to a front tea supply position (see FIG. 2) when tea is supplied to the tea cup. , A cup of tea is placed. The teacup stage 39 and its surroundings will be described with reference to FIGS. 7 to 10. FIG. 7 is a side view of the slide arm 40 and the slide guide 60. Further, FIG. 8 is a plan view of the slide arm 40 having the drinking water stage 39 formed at the tip thereof. The slide arm 40 slides in the slide guide 60 in the front-rear direction, and the slide guide 60 is fixed to the back surface of the back wall plate 20 of the tea feeding portion 21. Since the slide arm 40 has a known mechanism for moving in and out, detailed description thereof will be omitted.

When the slide arm 40 is moved rearward, as shown in the partial cross-sectional view of FIG. 9, the tea cup stage 39 is positioned at the retreat position X, and tea can be supplied to the pot P. When the slide arm 40 is moved forward, the teacup stage 39 is positioned at the pull-out position Y as shown in the partial sectional view of FIG. 10, and tea can be supplied to the teapot Q. A stopper 62 is attached to the slide arm 40. The stopper 62 contacts the rear surface of the back wall plate 20 of the tea feeding portion 21 when the slide arm 40 is slid forward and prevents the slide arm 40 from being pulled out excessively.

Next, the slide arm 40 and the stage position detecting means arranged around the slide arm 40 and the control means for controlling tea supply in the automatic tea supply device 1 will be described. A magnet 61 is attached to the slide arm 40. Further, a pull-out position detection switch 63 is fixedly attached to the front position of the slide guide 60. The magnet 61 moves back and forth together with the slide arm 40, and turns on the pull-out position detection switch 63 only when the teacup stage 39 of the slide arm 40 is at the pull-out position Y.

Therefore, the pull-out position detection switch 63 informs the control device that the slide arm 40 is at the front position, that is, the teacup stage 39 is at the pull-out position Y. This will be described with reference to the block diagram of FIG. FIG. 3 is a block diagram showing a hot water supply control device in the automatic tea supply device 1. That is, in this hot water supply control device, the control device 67 constitutes the main body thereof, and there is a tea supply switch SW provided on the panel switch PS as a switch pushed down by the operator, which instructs the control device 67 to start tea supply. The water supply valves 35 and 36 are driven via the control device 67. Further, the pull-out position detection switch 63 provided on the slide guide 60 notifies the control device 67 of the position of the teacup stage 39. Further, a third relay R3 is provided between the control device 67 and the water supply valve 36. The third relay R3 is turned on by a signal of a first timer TM1 described later, and cuts off or connects the drive signal to the water supply valve 36. The control device 67 has a driving means 66, a first timer TM1 and a second timer TM2, and further, a first relay R1 is provided between the first timer TM1 and the tea supply switch SW and a second timer TM2. A second relay R2 is arranged between the brown switch SW and the brown switch SW.

The driving means 66, the first timer TM1 and the second timer TM2 use known CPUs, RAMs, ROMs and the like. Here, the CPU performs various calculations based on the tea supply control program stored in the ROM, and temporarily stores necessary calculation data in the RAM. The first relay R1 or the second relay R2 connects or disconnects between the tea supply switch SW and the first timer TM1 or the second timer TM2 according to the signal from the pull-out position detection switch 63. Here, the first relay R1 is inverse to the signal from the pull-out position detection switch 63, and when the signal is off, the first timer TM1 and the tea supply switch SW are connected and the signal is turned on. At the time of, the first timer TM1 and the tea supply switch SW are disconnected from each other. On the other hand, the second relay R2 is compliant with the signal from the pull-out position detection switch 63, and when the signal is on, the second timer TM2 and the tea supply switch SW are connected and the signal is off. At times, the second timer TM2 and the tea supply switch SW are shut off.

Further, when the first timer TM1 receives a tea supply start command from the tea supply switch SW, the first timer TM1 supplies tea to the pot P via the relay R1 based on an OFF signal from the pull-out position detection switch 63. The driving means 66 and the third relay R3 are turned on for a suitable pouring time (for example, about 12 seconds). The second timer TM2 is a pouring time suitable for tea supply to the teacup Q via the relay R2 based on the ON signal from the pull-out position detection switch 63 when receiving the tea supply start command from the tea supply switch SW. The driving means 66 is turned on for (for example, about 4 seconds). In such a control device, first, a case of supplying tea to the teacup Q will be described. When the slide arm 40 is pulled out to set the teacup stage 39 to the pullout position Y in order to mount the teacup Q, the pullout position detection switch 63 is turned on, and this signal is transmitted to the first relay R1 and the second relay R2. As a result, the reverse first relay R1 is turned off, and the first timer TM1 is cut off from the tea supply switch SW. On the other hand, the forward second relay R2 is turned on and the second timer T M2 is connected to the tea supply switch SW.

Then, when the teacup Q is placed on the teacup stage 39 and the tea supply switch SW is pressed, the driving means 66 is turned on for a short time (for example, about 4 seconds) by the second timer TM2. At this time, since the third relay R3 is not turned on, the water supply valve 36 is not driven, only the water supply valve 35 is opened, and hot water is supplied from the water supply nozzle 33. Therefore, when tea is supplied to the teacup Q, overflowing hot water does not occur and it is safe. Next, the case of supplying tea to the pot P will be described. When the slide arm 40 is retracted to place the pot P on the tea supply unit 21 and the teacup stage 39 is moved to the retracted position X, the pull-out position detection switch 63 is turned off, and such a signal is transmitted to the first relay R1 and the second relay R1. Reached to relay R2.

As a result, the compliant second relay R2 is turned off, and the second timer TM2 is cut off from the tea supply switch SW. On the other hand, the reverse first relay R1 is turned on and the first timer T M1 is connected to the tea supply switch SW. Then, when the pot P is placed on the tea supply unit 21 and the tea supply switch SW is pressed, the driving means 66 is turned on for a long time (for example, about 12 seconds) by the first timer TM1. At this time, at the same time, the third relay R3 is also turned on by the first timer TM1, so that both the water supply valves 35 and 36 are opened and the hot water is supplied from the water supply nozzles 33 and 34. Therefore, tea supply for the teacup Q is not performed on the pot P.

Next, a second embodiment of the present invention will be described. The automatic tea supply device of the second embodiment is substantially the same as that of the first embodiment, except that the hot water supply control device is replaced with that shown in FIG. 4, and the retracted position is detected at the rear position of the slide guide 60. The switch 64 is fixedly attached. The retracted position detection switch 64 is turned on by the magnet 61 only when the slide arm 40 is in the rear position, and notifies the control device that the teacup stage 39 is in the retracted position X (FIGS. 7 and 8). reference). In the hot water supply control device of FIG. 4, the retracted position detection switch 64 is independently connected to the first relay R1a, and the extraction position detection switch 63 is independently connected to the second relay R2. Further, the first relay R1a is compliant like the second relay R2. Except this, the hot water supply control device in FIG. 4 is equivalent to that in FIG. Therefore, the automatic tea supply device of the second embodiment operates as follows.

First, the case of supplying tea to the teacup Q will be described. When the slide arm 40 is pulled out to set the teacup stage 39 to the pullout position Y in order to mount the teacup Q, the pullout position detection switch 63 is turned on, and this signal is transmitted to the second relay R2. As a result, the second relay R2 is turned on and the second timer TM2 is connected to the tea supply switch SW. On the other hand, at this time, since the retracted position detection switch 64 is in the off state, the first relay R1a is turned off and the first timer T M1 is cut off from the tea supply switch SW. Then, when the teacup Q is placed on the teacup stage 39 and the tea supply switch SW is pressed, the driving means 66 is turned on for a short time (for example, about 4 seconds) by the second timer TM2. At this time, since the third relay R3 is not turned on, the water supply valve 36 is not driven, only the water supply valve 35 is opened, and hot water is supplied from the water supply nozzle 33.

Next, the case of supplying tea to the pot P will be described. When the slide arm 40 is retracted to place the pot P on the tea feeding portion 21 and the teacup stage 39 is moved to the retracted position X, the retracted position detection switch 64 is turned on, and such a signal is transmitted to the first relay R1a. . As a result, the first relay R1a is turned on and the first timer TM1 is connected to the tea supply switch SW. On the other hand, at this time, since the pull-out position detection switch 63 is in the off state, the second relay R2 is turned off and the second timer TM2 is cut off from the tea supply switch SW. Then, when the pot P is placed on the tea supply unit 21 and the tea supply switch SW is pressed, the driving means 66 is turned on for a long time (for example, about 12 seconds) by the first timer TM1. At this time, at the same time, the third relay R3 is also turned on by the first timer TM1, so that both the water supply valves 35 and 36 are opened and the hot water is supplied from the water supply nozzles 33 and 34.

Next, a third embodiment of the present invention will be described. The automatic tea supply device of the third embodiment is substantially the same as that of the first embodiment, and the hot water supply control device is replaced with that shown in FIG. 5, and the panel switch PS is used for starting tea supply. As the switches, a pot switch SW1 dedicated to pot tea supply and a teacup switch SW2 dedicated to teacup tea supply are provided. In the hot water supply control device of FIG. 5, the pot switch SW1 is connected to the first timer TM1 via the first relay R1, and the teacup switch SW2 is connected to the second timer TM2 via the second relay R2. Except this, the hot water supply control device of FIG. 5 is equivalent to that of FIG. Therefore, the automatic tea supply device of the third embodiment operates as follows. First, when the slide arm 40 is pulled out to set the tea cup stage 39 to the pull-out position Y in order to mount the tea cup Q, the pull-out position detection switch 63 is turned on, and the relevant signal is transmitted to the first relay R1 and the second relay R2. Be transmitted to. As a result, the reverse first relay R1 is turned off, and the first timer TM1 is cut off from the pot switch SW1. On the other hand, the forward second relay R2 is turned on and the second timer TM2 is connected to the teacup switch SW2. Then, when the teacup Q is placed on the teacup stage 39 and the teacup switch SW2 is pressed, the driving means 66 is turned on for a short time (for example, about 4 seconds) by the second timer TM2. At this time, since the third relay R3 is not turned on, the water supply valve 36 is not driven, only the water supply valve 35 is opened, and hot water is supplied from the water supply nozzle 33. Even if the pot switch SW1 is depressed at this time, the tea supply operation for the pot by the first timer TM1 is not performed.

Next, when the slide arm 40 is retracted to place the pot P on the tea feeding portion 21 and the drinking cup stage 39 is moved to the retracted position X, the pull-out position detection switch 63 is turned off, and such a signal is output. It is transmitted to the first relay R1 and the second relay R2. As a result, the forward second relay R1 is turned off, and the second timer TM2 is cut off from the tea supply switch SW. On the other hand, the reverse first relay R2 is turned on and the first timer T M1 is connected to the tea supply switch SW. When the pot P is placed on the tea supply unit 21 and the pot switch SW1 is pressed, the driving means 66 is turned on for a long time (for example, about 12 seconds) by the first timer TM1. At this time, at the same time, the third relay R3 is also turned on by the first timer TM1, so that both the water supply valves 35 and 36 are opened and the hot water is supplied from the water supply nozzles 33 and 34. Even if the teacup switch SW2 is pressed at this time, the tea supply operation for the teacup by the second timer TM2 is not performed. Therefore, in the automatic tea supply device according to the second or third embodiment, the tea supply for the teapot Q is not performed for the pot P, or the tea supply for the pot P is provided for the teacup Q. Tea is never done. As shown in FIG. 6, the hot water supply control apparatus according to the fourth embodiment has a panel switch PS provided with a pot switch SW1 and a tea cup switch SW2, and a slide guide 60 provided with a pull-out position detection switch 63 and a retracted position. The position detection switch 64 may be provided. Also in this case, the tea supply operation similar to that of the automatic tea supply device of each of the above-described embodiments is performed.

As described in detail above, the automatic tea supply device 1 according to each of the embodiments has the detection switches 63 and 64 for detecting the position of the slide arm 40, and the signals from the detection switches 63 and 64 cause Since only tea supply suitable for the placed tea-receiving container is provided, an incorrect amount of tea is supplied due to an erroneous operation, which does not lead to overflowing hot water. Further, when the slide arm 40 is moved, the tea supply is stopped even during the tea supply, so that the tea water may fall on the operator's hand or the tea supply may flow out to the tea supply unit 21, the floor, or the like. Absent. Therefore, it is possible to realize an automatic tea supply device which is extremely safe, less likely to break down, and excellent in hygiene. It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various improvements and modifications can be made without departing from the gist of the present invention.
