Description

[Detailed Description of the Invention] The present invention relates to a coffee extractor in which a case containing coffee powder is taken in and out through an opening on the top surface of the container.

In conventional coffee makers, coffee beans are placed in a case, ground by a cutter, and then hot water is supplied to the ground coffee in the case to extract the coffee liquid. In order to take in and out the hot water, a horizontally rotatable hot water supply arm is provided at the upper end of the hot water supply pipe from the hot water supply mechanism, and a hot water outlet is provided at the tip of the hot water supply arm. However, since the hot water supply arm is rotated every time the case is taken in and out, the connection between the hot water supply arm and the hot water supply pipe wears out, causing hot water to leak. Since the lid is provided, when removing the case, the hot water supply arm must be rotated after opening the lid, which is cumbersome to operate.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to create a coffee machine with excellent operability, in which there is no risk of hot water leaking from the connection part, and the case can be taken out immediately after opening the lid. There is an extractor to provide.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a container body, and a storage recess 4 for removably storing a water tank 2 and a case 3 from above is arranged in parallel in the upper half of the container body. A lid 5 covering the upper side of the case 3 is pivoted via a hinge 6 so as to be able to rotate upward. Reference numeral 7 denotes a motor disposed within the container body 1 directly below the case 3, and is used to drive the cutter 8 disposed within the case 3. Reference numeral 9 denotes a base portion formed at the bottom of the vessel body 1 directly below the water tank 2, and where the water tank 2 is placed.
A drip mechanism 10 is provided as a hot water supply mechanism that heats water from the tank to make it hot water. The drip mechanism 10 has a heating tube 12 to which water is supplied from a water tank 2 and a sheathed heater 13 arranged in a meandering manner in parallel on the lower surface of a heating plate 11. oriented upwards.
On the other hand, reference numeral 14 denotes a diffuser detachably attached to the upper surface of the case 3, which has a protrusion 15 protruding from the center of the upper surface, and flowing grooves 16a formed at equal intervals around the protrusion 15. A circular protruding strip 16 is provided, and a plurality of water holes 17 are bored in the peripheral portion. 18 is a bendable bellows part 18 in the middle part
A connecting pipe with heat resistance and elasticity having a
One end of this is inserted into the container 1 through an opening 1b provided near the hinge 6 on the upper surface 1a of the container 1 and connected to the outlet end 12a of the heating tube 12 by fitting, and the other end is It is held in contact with the inner surface of the lid 5 by ribs 19, 19 and 20, 20 protruding from the inner surface of the lid 5, and the bellows portion 18a at the middle portion corresponds to the hinge 6. Reference numeral 21 denotes a substantially L-shaped hot water supply spout connected to the other end of the connecting pipe 18 by fitting, and a valve body 22 serving as a valve device that closes by its own elastic force is provided at the outlet of this spout. and,
The outlet portion of the hot water supply spout body 21 is positioned such that when the lid 5 is closed, a convex portion 15 protruding from the diffuser 14 enters the inside, and the upper end of the convex portion 15 pushes the valve body 22. The valve body 22 is opened by raising the valve body 22 against its own elastic force. In addition, 23
2 is a switch that selectively energizes the motor 7 and the sheathed heater 13.Although not shown, a lid switch that turns off when the lid 5 is opened is provided, and this switch 23 and the lid switch are connected in series. The sheathed heater 13 is energized. Further, 24 is a bottle placed on the heating plate 11.

Next, the operation of this embodiment configured as above will be explained. After putting coffee beans in the case 3 and attaching the diffuser 14, and putting water in the water tank 2 and closing the lid 5, when the motor 7 is energized by operating the switch 23, the coffee beans are dispersed by the cutter 8. is crushed. Next, when the sheathed heater 13 is energized by operating the switch 23, the water supplied from the water tank 2 is heated in the heating pipe 12 of the drip mechanism 10 and becomes boiling water, which rises in the connecting pipe 18 due to its boiling pressure. from the hot water supply port body 21 to the diffuser 1
4. Then, it is diffused and supplied to the surroundings from the flow channel 16a of the diffuser 14, enters the case 3 through the water inlet 17, passes through the coffee powder in the case 3, becomes coffee liquid, and is stored in the bottle 24. On the other hand, when the lid 5 is opened after extracting the coffee liquid, the power supply to the sheathed heater 13 is cut off by a lid switch (not shown), and the hot water supply spout body 21 is rotated upward together with the lid 5 to be separated from the diffuser 14. Then, the valve body 22 separates from the convex portion 15 and is closed by its own elastic force. When the lid 5 is opened in this manner, the hot water supply spout body 21 is rotated upward and separated from above the case 3, so that the case 3 can be immediately taken out and cleaned.

As described above, according to this embodiment, since the hot water supply spout body 21 attached to the lid 5 and the drip mechanism 10 are connected by the connecting pipe 18 having the bendable bellows part 18a, the connecting part does not wear out unlike the conventional structure. This prevents hot water from leaking, and the case can be taken out immediately after opening the lid 5, providing excellent operability. Further, since the valve body 22 is closed at the same time as the lid 5 is opened, even if hot water is generated by the residual heat of the heating plate 11 after the sheathed heater 12 is turned off, the hot water will not be discharged from the hot water supply opening body 21. Moreover, since the sheathed heater 12 is also cut off when the valve body 22 is closed, there is no danger that the pressure in the heating tube 12 and the connecting tube 18 will rise abnormally.

Incidentally, since the entire connecting pipe 18 has heat resistance and elasticity and can be bent sufficiently, the bellows portion 18a may be provided as necessary, and the cutter 8 in the case 3 and this cutter 8 can be Drive motor 7
may be provided as necessary.

As is clear from the embodiment described above, the present invention has no risk of hot water leaking from the connection part.
Moreover, the case can be taken out immediately after opening the lid, and a coffee brewer with excellent operability can be provided.
