Description

  The present invention relates to a drainage device for temporarily storing washing wastewater or the like in a beverage supply device, and in particular, a beverage supply provided with a detachable drainage storage container and a detection unit that is disposed in the container and detects its full water state. The present invention relates to a drainage device.

As such a conventional drainage device, a device as described in JP-A-10-188126 is known. This device is installed in beverage vending machines that supply and sell beverages in cups, such as washing waste water in the machine, excess water in the storage tank (overflow water), beverages that spilled when pouring beverages into the cups, etc. A drainage bucket (drainage container) for collecting and temporarily storing the wastewater is provided. When the drainage bucket becomes full, the full level is detected by detecting the water level when the drain is full by a float (detection unit) disposed therein. Here, when this full water condition is detected, the manager or the like takes out the float by hand from the drainage bucket in a timely manner, removes the drainage bucket from the installation position, and discards the drainage inside. In addition, when returning an empty drain bucket, the float is manually returned to the interior after the drain bucket is installed.

Detects rotation to a preset position And a setting switch 91 and the like that. Here, the float 81 is configured to always hang down from a predetermined position with respect to the rotating plate 86 by a guide roller 92 that guides the string portion 82. The full water detection device 80 is attached to the body of a beverage dispenser (not shown) via a base 95.

In the beverage dispenser configured as described above, the beverage cooking unit 47 for cooking the beverage is automatically washed as necessary, and the washing drainage is supplied to the drainage bucket 71 via the water collecting tray 58 provided at the lower part of the bend stage 57. Temporarily stored. Further, hot water and cold water overflowing from the hot water tank 9 and the cold water tank 8 are drained into the drainage bucket 71 through the hot water discharge pipe 34 and the cold water discharge pipe 28, respectively. Further, when the hot water tank 9 and the cold water tank 8 are inspected and cleaned, residual water in these tanks 8 and 9 is opened by the hot water drain valve 37 and the cold water discharge valve 21, respectively. It is drained into the drain bucket 71 through the drain pipe 22.
In addition, when a beverage is poured out from the beverage cooking unit 47 into the cup 48, or when the cup 48 is taken out from the bend stage 57 by the customer, the beverage spills out of the cup 48 and soils the surrounding bend stage 57 and the like. is there. The dirty bend stage 57 and the like are cleaned by a service person who manages the bend stage 57, for example, by operating a flexible hose 38a connected to the hot water drain pipe 38 via the hot water discharge valve 37. Then, the cleaning waste water is also stored in the drain bucket 71 via the water collecting tray 58.

By the way, the waste water is collected as described above in the drain bucket 71 (see FIG. 2A) installed at a predetermined installation position in the machine, and the water level of the waste water stored therein rises and reaches the predetermined water level. Then, as shown by a broken line in the figure, the float 81 suspended by the string portion 82 is floated and pushed up on the water surface of the drainage, and the string portion 82 connecting the tip of the actuator 85b and the float 81 is loosened. That is, the dead weight of the float 81 does not act on the tip of the actuator 85b, whereby the tip of the actuator 85b is rotated upward, the limit switch 85 is operated, and the full state of the drain bucket 71 is detected. Further, when a full water state is detected by the limit switch 85, the supply of beverage by the beverage dispenser is stopped by a control means (not shown).
Then, when a serviceman or the like confirms that the drainage bucket 71 of the beverage dispenser is in such a full state, the drainage bucket 71 is removed from a predetermined installation position, and the wastewater inside thereof is discharged and discarded. Here, when the drainage bucket 71 is removed from the predetermined installation position, the full water detection device 80 is pressed by the front end of the drainage bucket (the right side of the drainage bucket shown in FIGS. 2A and 2B). The portion 88 is biased by the coil spring 90 about the support shaft 87 together with the rotating plate 86 in accordance with the removal operation of the drain bucket 71 (movement of the drain bucket in the direction of arrow A in FIG. 2B). It rotates in the direction of removing the drain bucket 71. At this time, the float 81 that is inside the drain bucket 71 and is connected to the rotating plate 86 via the string portion 82 is pulled up upward in conjunction with the rotation of the rotating plate 86 and is moved to the outside of the drain bucket 71. Moving. When the rotating plate 86 is rotated to a predetermined position, the rotating plate 86 is locked by the locking member 89, and the locked state is maintained.

  In addition, when returning the empty drain bucket 71 from which the drainage has been discharged to a predetermined installation position, the pressing portion is moved along with the mounting operation of the drain bucket 71 (movement of the drain bucket in the direction of arrow B in FIG. 2B). 88 is pressed by the front end portion of the drainage bucket 71, and rotates together with the rotating plate 86 around the support shaft 87 against the bias of the coil spring 90. At this time, the float 81 that is above the drain bucket 71 and is suspended by the rotating plate 86 via the string portion 82 moves downwardly in conjunction with the rotation of the rotating plate 86 and moves to the drain bucket. 71 is hung at a predetermined position where the water level in the full state can be detected. When the drain bucket 71 is mounted at a predetermined installation position, the rotating plate 86 rotates to a predetermined position corresponding to the draining bucket 71, and a setting pin 92 provided on the rotating plate 86 is provided on the base 95. When the actuator 91b of the bucket setting switch 91 is pressed, the bucket setting switch 91 is operated, and it is detected that the drain bucket 71 is set at the installation position. Furthermore, when the setting to the installation position of the drainage bucket 71 is detected by the bucket setting switch 91, the beverage dispenser is in a state in which the beverage can be supplied by a control means (not shown).

As described above, according to the drainage device 70 of the beverage dispenser of the present embodiment, the float 81 is reliably put in and out of the drainage bucket 71 without manual operation, linked to the operation of mounting and removing the drainage bucket 71. Therefore, it is possible to easily attach and detach the drain bucket 71, and to prevent damage to the device caused by a mistake in entering and leaving the drain bucket 71 of the float 81 and detection leakage of a full water state. Therefore, the operability and reliability of the apparatus can be improved.
The full water detection device 80 is rotatably supported by a float 81 that detects the water level of the drain bucket 71, a limit switch 85 that detects a full state of the drain bucket 71 based on the detected water level of the float 81, and a support shaft 87. A rotating plate 86 provided with a pressing portion 88 against which the float 81 and the drain bucket 71 that are suspended via the string portion 82 abut, a coil spring 90 that urges the rotating plate 86 to turn to one side, and a rotating plate Since the locking member 89 that locks the 86 at a predetermined position is provided and is simply configured, the drainage device 70 of the beverage dispenser with less failure and low cost can be provided.

The present invention is not limited to the apparatus shown in the present embodiment. For example, the full water detecting means for detecting the full water state by detecting the water level in the drainage bucket is not limited to the limit switch, and may be light or ultrasonic. Of course, a system using an electrode or the like may be used. Further, the portion of the drainage bucket 71 that abuts against and presses the pressing portion 88 is not limited to the front end portion, and may be the left and right side portions or the rear portion. That is, the application of the embodiment of the present invention can be changed within the scope of the gist.
In addition, the drainage device of the beverage supply device of the present invention can be widely applied to cup-type vending machines, tea machines, and the like.
