Next, the operation of the above configuration will be explained. To extract coffee liquid from the state shown in FIG. 3, the case 18 is first removed from the case storage chamber 5 and coffee beans are placed inside. To remove the case 18,
Lift the case 18 upwards and remove the annular rib 23 from the annular protrusion 22 (at this time, remove the hot water pan 42
(will be pushed into the case 18 side against the elastic force of the coil spring 51), then just pull it out toward you. After adding coffee beans, case 1
After covering the upper surface of the case 18 with the pouring cap 33 and the lid 38, the case 18 is placed in the case storage chamber 5 as follows. First, the guide portion 45 of the hot water receiving portion 42
is brought into contact with the lower surface of the ceiling 13 of the case storage chamber 5, and in this state, by lifting the case 18 and pushing it to the back side, the hot water receiving part 42 is moved against the elastic force of the coil spring 51 to open the case. 18 side (lower side), the guide part 45 is gradually slid to the lower side of the hot water supply part 35, and the lower end of the receiver 20 is placed on the annular convex part 22 (see FIG. 4). Thereafter, when the annular rib 23 is aligned with the annular convex part 22 by pushing the case 18 further into the back, the upper end of the hot water pan 42 is aligned with the shoulder of the hot water supply part 35, and at the same time, the case 18 is pressed against the coil spring. The annular rib 23 is lowered by the elastic force 51 and its own weight, and the annular rib 23 fits into the annular protrusion 22, and the case 18 is placed in the case storage chamber 5. In this state,
The hot water pan 42 is held in elastic contact with the hot water supply section 35 by the elastic force of the coil spring 51, that is, the central portion of the guide section 45 of the hot water pan 42 is held in close contact with the flange 37 of the hot water supply section 35. , the hot water receiving part 42 is the hot water supply part 3
5 is now watertightly connected. Then, after taking out the water tank 8 and injecting water into the inside, the water tank 8 is reinstalled in the water tank storage chamber 6, and then,
When the motor 16 is started, the grinding body 28 rotates and the coffee beans in the case 18 are ground. When the electric heater 11 of the hot water supply mechanism 10 is energized after pulverization, the water flowing from the water tank 8 into the heating pipe 12 is sequentially turned into hot water, and this hot water is pushed up inside the hot water pipe 14 by boiling pressure, and the hot water is heated to the hot water supply section. It reaches 35.
Since a hot water pan 42 is watertightly connected to the outflow side end of the hot water supply section 35, hot water flows from the hot water supply section 35 to the hot water pan 42, and from the lower end of the hot water pan 42 is poured into the case 18. Recessed portion 34 of hot water cap 33
Squirt on top. In this case, between the hot water supply part 35 and the case 18, there is provided a lid 38 of the case 18, and a coil spring 5 inserted and supported by the insertion hole 41 of the lid 38.
1, the hot water receiving part 4 is held in elastic contact with the hot water supply part 35.
2, this hot water pan 42 and the insertion hole 4 of the lid 38
1, the hot water vapor ejected from the hot water receiving part 42 through the hot water supply part 35 is confined within the case 18 and is not leaked to the outside. Therefore, the vapor will not wet the ceiling 13 of the case storage chamber 5, etc. In addition, the sound of hot water emitted from the outlet of the hot water pan 42 is also suppressed by the lid 38 and the sealing member 4.
Since the sound is emitted within the case 18, which is closed by 6, this jetting sound does not leak directly to the outside. Therefore, the user does not hear the jetting sound as a very loud sound, and the noise during hot water supply is reduced. is small. On the other hand, the hot water spouted onto the concave portion 34 is temporarily stored in the concave portion 34 and diffused to the surrounding area through the gap between the ribs 34b, drips onto the coffee powder from the pouring hole 33a, and is then filtered by the filter body 26. This becomes coffee liquid and is stored in the bottle 15.

Further, in this embodiment, the sealing member 46 is configured to be brought into pressure contact with the lid 38 by the elastic force of the coil spring 51, so that the sealing member 46 does not need to be fixed to the lid 38 by a fixing means such as adhesive.
and the lid 38 can be improved,
This is more convenient for maintaining airtightness between the hot water pan 42 and the lid 38.

When the coffee beans are ground in the case 18 as in this embodiment, the coil is used to prevent the lid 38 from being lifted from the top surface of the case 18 due to vibrations and splashing of coffee grains when the coffee beans are ground. Since this can be prevented by the elastic force of the spring 51, an additional effect of reliably preventing the coffee powder from flying out of the case 18 can be obtained.

[Effect of idea]

As is clear from the above description, the present invention allows the hot water supply unit and the top surface of the case to be airtightly connected through the hot water pan, the lid, and the sealing member, thereby preventing hot water vapor from being released to the outside. There is no risk of the ceiling of the case storage room being wetted by steam, and the sound of gushing hot water can be prevented from directly leaking outside, resulting in an excellent effect of reducing noise during hot water supply. .
