A shaft joint 20 connected to the shaft joint 20 is fixed. Reference numeral 21 is an extraction port provided in the bottom frame 15 corresponding to the lowest part of the bottom plate portion 15a, and 22 is a valve plate that opens and closes the extraction port 21 from the bottom side. The valve plate 22 is provided in the vicinity of the extraction port 21 of the bottom frame 15 via a pin 23 so as to be able to open and close, for example, to rotate.The valve plate 22 has an operating arm 22a directed downward. It is integrally protruded.

Reference numeral 24 denotes a torsion coil spring wound around the bottle 23, which always biases the valve plate 22 in the direction of the arrow claw, which is the closing direction. 26' is a cup stored in the cup storage part 3 and placed on the upper surface of the heating plate 7. A bulging part 25a is provided on the upper edge of the cup 26', and the cup 25 is placed in the extraction liquid receiving position, i.e. When correctly placed on the heating plate 7, the operating arm 22a is rotated in the direction opposite to the arrow by the swollen portion 25a against the elastic force of the torsion coil spring 24, and the valve plate is rotated. 22 opens the extraction port 21.

26 is a lid that removably closes the upper surface of the case portion 14;
A pouring hole 26a facing the outlet 9a of the hot water pipe 9 is provided in the center of this, and a diffusion plate 27 facing below the pouring hole 26a is integrally molded with the lid 26 via legs 27a. ing.

Next, the operation of this embodiment configured as above will be explained. First, a predetermined amount of coffee beans is stored in the filter case 13, a predetermined amount of water is supplied in advance into the water storage tank 5, and when the motor 11 is energized, the blades 19 are rotationally driven via the shaft coupling 12.20. Coffee beans are ground into powder with a predetermined coarseness. When the grinding of the coffee beans is completed, the motor 11 is turned off and the sheathed heater (not shown) of the heater 7 is energized instead.
Water supplied into the heater 7 by the water supply pipe 8 is heated to boiling water, moves up the water supply vibrator 9, and is discharged from the outlet portion 9a. This hot water passes through the pouring hole 26a to the diffusion plate 27.
As a result, the coffee is dispersed and dripped around the inner circumference of the filter case 13, mixed with the coffee powder stored on the filter 16, and filtered by the filter 16, thereby extracting coffee. The extracted coffee flows down into the extraction port 21 along the bottom plate part 15a, and is poured from the extraction port 21 into a cup.
It is dripped and stored in the tube 25. By placing the cup 25 on the heater 7, it is appropriately preheated and kept warm. Now, when all of the water in the water storage tank 5 is heated to boiling water by the heater 7, the supply of hot water into the filter case 13 ends, and after a predetermined period of time has passed, the filter 16
Extraction of coffee from the above coffee powder is also completed. Then, when the supply of hot water is finished, the power supply to the sheathed heater (not shown) of the heater 7 is cut off, the cup 25 is removed from the cup storage section 3, and the coffee stored in the cup 25 is transferred to the coffee cup and consumed. It is provided to

Further, the filter case 13 is removed from the filter case housing 4, carried to a sink, the coffee grounds remaining in the filter case 13 are thrown away, and the inside is cleaned in preparation for the next use. Therefore, when the cup 25 is removed from the cup storage part 3 and the filter case 13 is removed from the filter case storage part 4,
In either case when removed from the cup 25, the bulge 2
5a is separated from the operating arm 22a of the valve plate 22, the valve plate 22 is rotated in the direction of the arrow claw by the spring force of the torsion coil spring 24, and the extraction port 21 is closed by the valve plate 22 from the lower surface side.

By the way, for example, if the valve plate 22 is not provided, the coffee that adheres to the inner surface of the filter case 13 or remains contained in the coffee powder on the filter 16 may flow downward from the extraction port 21 over time. If the coffee grounds are irregularly dripped onto the substrate 2 of the cup storage section 3 after the cup 25 is taken out, it may stain the top surface of the substrate 2 and the top surface of the heater 7. Therefore, when the filter case 13 is removed from the substrate 1 and carried to a sink or the like, there is a problem that the coffee that drips irregularly from the extraction port 21 stains the floor, clothes, etc.

However, according to the above configuration, the extraction port 21 is blocked by the valve plate 22 both when the cup 25 is removed from the cup storage section 3 and when the filter case 13 is removed from the filter case storage section 4. From, cup 25
The upper surface of the substrate 2 and the upper surface of the heater 7 after being taken out will not get dirty, nor will the floor, clothing, etc. get dirty when the filter case 13 is carried to a sink or the like.

In addition, in the above configuration, the extraction port 21 is closed from the bottom side by the valve plate 22, so compared to, for example, a structure in which the valve plate is provided at the bottom of the filter case at the upper end of the extraction port.
Coffee powder gets caught between the extraction port 21 and the valve plate 22,
Therefore, the extraction port will not be completely blocked due to caught coffee powder, and even if it gets caught, it can be easily removed without being obstructed by the filter 16, perforated plate 17, etc. This has the effect of making it easy to clean the valve mechanism as it can be removed by washing with water.Furthermore, with the above configuration, assembly is easy and manufacturability is improved, and replacement in the event of valve plate failure is also easy. can.

In the above embodiment, since the valve plate 22 is opened by directly pushing the operating arm 22a with the bulge 25a of the cup 25, the bulge 25a of the cup 25 is connected to the extraction port 21.
The extraction port 21 is opened only when the cup 25 is placed directly under the heating plate 7, and the extracted coffee is poured into the cup 25.
Although it has the effect of ensuring that the drips drip into the cup 25 without dripping outside, the cup 2 is made by omitting the bulging portion 25a.
The operating arm 22a may be pushed by the upper peripheral wall of 5.
Alternatively, a heat radiation prevention lid or the like may be attached to the top surface of the cup 25, and the actuating arm 22a may be pushed by the lid. In other words, when the cup is placed facing the extraction port, the lower surface of the extraction port The valve plate may be configured to be moved in the opening direction.

In addition, in the above embodiment, there is a blade 1 inside the filter case 13.
9 is provided to immediately pour hot water onto the ground coffee powder after grinding the coffee beans, resulting in coffee with good flavor. Needless to say, the present invention can be applied to a so-called coffee extractor in which coffee powder is stored in the filter case 13 and hot water is poured into the filter case 13, and it is also possible to extract beverages other than coffee.

As explained above, when the cup is removed from below the brewing spout after brewing a beverage, or when the filter case is carried for cleaning after brewing, the remaining liquid attached to the inner surface of the filter case is extracted. It is possible to reliably prevent dripping from the mouth and not to contaminate the floor, clothes, equipment, etc., and the extraction port is closed from the bottom side with a valve plate to prevent coffee powder from adhering to the valve plate. It is possible to provide a beverage maker which has excellent effects in that the extraction port can be reliably blocked without being difficult to clean, and the valve mechanism thereof can be easily cleaned.
