Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a coffee making machine in which a coffee bean grinding mechanism and a coffee liquid extraction mechanism are housed in a box-shaped main body.

[Technical Background of the Invention J A conventional coffee making machine has a case mounting part on the upper surface of the main body in which a motor and a hot water supply mechanism are installed, and a water tank setting part and a water tank mounting part on both upper and lower sides of the front part of the main body, for example. A case with a bottle mounting neck is provided, and a case containing coffee beans is set on the case mounting section and the motor is started to rotate the grinding body in the case to grind the coffee beans, and then the coffee beans are removed from the water tank. The water was heated to boiling water by the hot water supply mechanism and supplied into the case, and the coffee liquid that flowed out from the outlet after being filtered by the filter member of the case was stored in the bottle.

1. Problems with backfl technology] However, in conventional coffee making machines, the case is exposed, so when coffee beans are crushed at d5, they are bounced off by the crushing body and collided with the peripheral wall of the wooce. There was a problem in that the sound leaked out to the outside and the noise was loud.

[Object of the Invention] The object of 4.5 is to provide a coffee making machine that can reduce noise during grinding of coffee beans.

L Summary of the Invention] The present invention has a main body formed in a box shape with an open front, a case storage chamber partitioned by walls within the main body box, and a front opening of the case storage chamber 1iT! By opening and closing the case, the case can be placed in a closed room to prevent the banging sound generated when grinding beans from leaking directly to the outside, thereby reducing noise. A steam vent hole is formed in the door, and by arranging the case in a closed room, the steam that tends to get trapped in the room when coffee liquid is extracted can be discharged to the outside.

The front opening of the case storage chamber 8 has a door 56 for opening and closing it.
is installed at the center. This door 56 is of a horizontal type that rotates around the left end, and an iron piece 57 is attached to the right side of the door.
The structure is such that the closed state is maintained by being attracted to the The door 56 has a plurality of steam vent holes 59 formed in its upper part, and a protrusion 56a that protrudes into the case storage chamber 8 is integrally formed in its upper edge.

Next, the operation of the above configuration will be explained.

Case 3/I and water tank 26 are placed in storage chambers 8 and 1, respectively.
0, the coffee beans are stored in the case 34, and water is stored in the water tank 26. Then, the case 34 is stored in the case storage chamber 8, the door 56 is closed, and the water tank 26 is stored in the water tank storage chamber 10. When the motor 15 is started in this state, the cutter 41 rotates and grinds the coffee beans in the case 34. At this time, the coffee beans are splashed by the cutter 41 and the case body 3
Although the case 34 collides with the inner peripheral surface of the door 5 and makes a banging sound, the case 34
Since the device is housed in a case storage chamber 8 closed by 6, the hitting sound does not leak directly to the outside, so the user does not hear it as a very loud sound, resulting in low-noise operation.

After the coffee beans are ground, when the electric heater 20 is energized, the water flowing into the heating pipe 21 from the water tank 26 is heated and quenched, and is passed from the hot water supply pipe 23 to the hot water guide path 45 of the quenching diffuser 43.
supplied within. This hot water is guided by the drying guide path 45, flows into the lake diffuser 43, and flows down into the case main body 36 from the container 8044. The coffee liquid that has passed through the coffee powder and been filtered by the filter member 35 and flowed down into the receiver 37 flows out from the outlet 38 and is stored in the bottle 24. When this coffee liquid is extracted, steam leaks into the case storage chamber 8 from the gap between the hot water supply pipe 23 and the insertion port 46, or steam from the coffee liquid stored in the bottle 24 is received by the lid 25. The steam rises from the hole 25a and flows into the case storage chamber 8 through the frontage 51, but this steam is guided forward by the inclined upper surface 8a of the case storage chamber 8 and flows out through the steam vent hole 59 of the door 56. Therefore, problems such as dew condensation occurring on the inner surface of the case storage chamber 8 and subsequent cleaning becoming troublesome can be prevented as much as possible. In this case, the projection b6a of the door 56 creates a condition in which there is only a small gap with a certain length in the front-rear direction between the door 56 and the upper surface of the case storage chamber 8, making it difficult for steam to pass through. Because there are
Most of the steam will flow out from the five steam vents. Therefore, since there is almost no steam flowing out other than from the place where steam should normally escape (steam vent hole 59), there is no risk of causing the user to feel uneasy about the possibility of malfunction.

1. Effects of the Invention] As explained above, in the present invention, the case is stored in a case storage chamber that can be closed with vinegar.
It is possible to prevent the knocking sound generated when coffee beans are crushed inside the case from directly leaking outside, allowing for low-noise operation.In addition, a steam vent hole is formed in the door to prevent coffee liquid from leaking out. It has the excellent effect of being able to exhaust the steam that tends to get trapped inside the case storage chamber during extraction to the outside.
