Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a beverage comprising a pulverizer for pulverizing raw materials such as coffee beans, a basket having a filter for receiving the pulverized raw materials, and a water heater for supplying hot water into the basket. 2H related to manufacturing machines.

The conditions for extracting delicious, flavorful coffee are to immediately pour boiling water over the coffee beans and filter them after grinding. Therefore, in order to obtain delicious coffee at home, it is necessary to have both a mill function for grinding beans and a drip function for supplying hot water immediately after grinding.

Conventionally, a coffee boiler that has both the milling function and the dripping function has a basket that has a drive motor, a grinding body that is rotated by the motor to grind beans, and a filter that receives the ground coffee powder. There was a filter that directly supplied hot water to the machine, but the filter needed to be strong because the coffee beans were ground in the same room.
Also, fine-mesh filters were essential for filtering coffee. For this reason, conventional filters have been made of strong materials such as stainless steel and have a fine mesh of about 180 mesh. However, the wire diameter of stainless steel is 1
If you grind coffee beans, etc. repeatedly, the mesh will tear and no longer function as a filter, resulting in coffee powder getting mixed into the extract, or coffee powder The boiling water was not soaked sufficiently, resulting in only a rough and bitter extract.

Furthermore, the filter itself has the disadvantage that it bends during grinding of beans, etc., and as a result, grinding cannot be carried out efficiently.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

First, a predetermined amount of water is supplied into the water storage tank 33, coffee beans as a raw material are put into the basket 6, the basket lid 26 is placed on the partition plate 16 of the container 1, and the grinding body 2o The joint 21 engages with the joint 6 attached to the motor rotating shaft 4.

Next, the opening 4o of the hot water supply pipe 39 is set so as to face the hot water tray 27, and the lid 41 of the container 1 is closed. The safety switch 47 is then opened. Furthermore, by placing the glass container 29 with the glass container lid 3o set on the heat insulating plate 35, the socket 31 of the glass container 29 is placed in the basket 6.
Pour 1] Facing 12.

Therefore, when the power switch 46 is closed and the contacts (T+T2) of the changeover switch 46 of the operation section are closed, the drive motor 3 is energized and its rotating shaft 40 rotations are rotated through the joint 6.21. It is transmitted to the crushing body 2o. The coffee beans in the basket 6 are crushed by the rotation of the crushing body 2o, and are ground to an appropriate coarseness to become coffee powder. Then, when the contacts ('r, -'r5) of the changeover switch 46 are closed, the drive motor 3 is cut off due to the opening between the contacts (T, T2), stops rotating, and the coffee powder is transferred to the filter 22. When the contact piece (T+T3) is closed, the sheath heater 36 inside the heating body 34 is energized and generates heat, thereby heating the water inside the heating pipe 3.

Therefore, the water boils and expands in the heating pipe 37, and the hot water rises to the hot water pipe 39 side by the action of the check valve 38. 27 and dripping onto the coffee powder in the basket 6 through the small hole 28, the coffee components are extracted while the hot water passes through the coffee powder and passes through the filter 22, and the coffee is poured through the spout 12. The liquid accumulates in the glass container 29.

When the sheathed heater 36 generates heat, it heats the bottom surface of the glass container 29 via the heat insulating plate 35, and when the water in the water storage tank 33 runs out, the thermostat 43 operates, keeping the coffee liquid in the glass container 29 at an appropriate temperature. be done.

As described above, according to the present embodiment, the container 1 having the water storage tank 33 is provided with the basket 6 having the grinding body 2o and the filter 22, and the water heater, and coffee beans etc. are ground by the grinding body 2o in the basket 6. After that, hot water is immediately supplied into the basket θ through the hot water supply pipe 41 to mix the coffee powder and the hot water, and the filter 22
The system is configured to extract coffee liquid by filtering it through filtration.It is possible to extract coffee with rich flavor without losing aroma, and its operation is extremely simple. moreover,
The filter 22 has a double structure of a coarse filter 22 & with a thick wire diameter on the side of the grinding body 20 and a fine filter 22b on the opposite side, so that when grinding coffee beans etc. with the grinding body 20, the filter 22 Since the collision force and pressure applied to the upper surface are absorbed by the filter 221, which has a coarse mesh and a large wire diameter, durability is greatly improved. In particular, when grinding hard objects such as coffee beans using the blade-type grinder 2o as in this embodiment, a large force is applied to the filter when cutting the coffee beans immediately after the start of grinding. Since the particle size of the particles is still similar and does not directly collide with the lower fine-mesh filter 22b, the durability of the fine-mesh filter 22b, which actually performs the filtration function, is significantly improved. In addition, since the filter 22 has a double structure, and one of the filters is a coarse filter 222L with a large wire diameter, downward deflection during crushing is reduced, and the crushing body 2o
This makes grinding more effective. In addition, conventionally, a particle size selection filter has been proposed in which 11 vanes are installed directly under the crushing body 2o, and an extraction filter is provided in a space below the vanes, but this is complicated in structure and requires a large number of parts. However, in the embodiment, the filter 22 is double layered, with a slight gap or in close contact with each other, increasing the strength of the filter itself. , easy to configure,
Cleaning will also be much easier.

As is clear from the above description, according to the present invention, the filter has a coarse-mesh filter on the pulverizing body side and a fine-mesh filter on the opposite side, thereby greatly improving the durability of the filter. This provides excellent effects such as less deformation of the filter during raw material pulverization and more efficient pulverization.
