Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a coffee boiler that automatically performs the process of grinding coffee beans and supplying hot water to the ground coffee powder.

(b) Prior Art There has not been a structure in the past in which a sieve plate is disposed below a cutter and a diffusion gutter is attached to the lower surface of the sieve plate using a locking claw as in the present invention.

However, when engaging the locking pawl of the diffusion gutter with the locking hole formed in the sieve plate, if this locking hole is formed below the cutter, the locking pawl will also fit into the cutter. When coffee beans are ground by the cutter located below, the coffee beans being rotatably ground collide with the protruding locking pawl, which has the disadvantage of causing wear or damage to the locking pawl.

C. Purpose of the invention Therefore, the present invention aims to prevent wear and damage of the locking claw by locating the locking claw of the diffusion gutter as centrally as possible so that the locking claw does not exist below the cutter. With the goal.

D. Structure of the invention The structure of the invention includes an upper case equipped with a cutter for crushing coffee beans and a sieve plate for causing the crushed powder to fall downward, and a case that is engaged with the lower surface of the upper case and has an open upper surface. comprising a lower case in which a filter is disposed inside, a diffusion gutter that abuts and engages with the lower surface of the sieve plate, a motor that drives the cutter, and a water heater that supplies hot water to the diffusion gutter;
A locking hole is formed in the center of the sieve plate, and a locking claw formed on the upper surface of the diffusion gutter is projected and engaged with the locking hole, and is particularly suitable for the diffusion gutter. This is intended to prevent the formed locking pawl from being damaged due to rotation of the coffee beans by the cutter.

Example 1 of the invention 1 is a main body of a coffee boiler, with a tank 2 for storing water on the top surface and a mounting base 4 in which a motor 3 is installed.
and a mounting table 6 on which the decanter 5 is mounted. The placing portion 6 exposes the heater 7 so that the decanter 5 can be directly placed on the heater 7. The decanter 5 has a handle 8 attached to its outer surface and a lid 9 at its upper opening.
has been established. The motor 3 has a lower joint 10 slightly protruding from the upper surface of the mounting base 4. 1
Reference numeral 1 denotes a lower case which is detachably arranged on the upper surface of the mounting base 4, and has an open upper surface, a cylindrical protrusion 12 rising up from approximately the center of the bottom surface, and a knob 13 formed on one side of the bottom surface. . The knob 13 is hollow, and forms a discharge hole 18 facing the upper opening of the decanter 5, and also forms a discharge hole 18 facing the upper opening of the decanter 5.
It communicates with the inside of 1. 14 is the lower case 1
1, the filter has a cylindrical shape as a whole, and has a rising cylindrical part 15 approximately in the center of the bottom surface that covers the protruding part 12 from the periphery.
The upper end surface is formed lower than the protruding portion 12, and the cylindrical portion 15 is a blind portion as shown. The bottom and side surfaces of the filter 14 are mesh-shaped, and bars 16 are provided here and there. 1
Reference numeral 7 denotes a cylindrical upper case that is attached to and detached from the upper surface of the lower case 11, and has a plurality of through holes 19 in the bottom surface.
A sieve plate 20 is provided, and a cover plate 22 having suction holes 21 is attached to and removed from the upper opening thereof.
The center of the sieve plate 20 is slightly bulged upward to form a bulge 23, an insertion hole 24 is bored in the center, and a plurality of locking holes 25 are bored around the insertion hole 24. are doing. That is, the locking hole 25 is located at the center of the sieve plate 20. Reference numeral 26 denotes a diffusion gutter that is attached to and detached from the lower surface of the upper case 17, and includes a circular water collecting part 27, four water sprinkling parts 28 extending radially from the water collecting part 27, and a substantially L-shaped mounting part. It consists of 29. A cylindrical mounting portion 30 is formed in the water collecting portion 27, and four locking pawls 31 are formed at the upper end of the mounting cylinder portion 30 to engage with the locking hole 25.
A water sprinkling hole 32 is bored in the water sprinkling section 28 .
The mounting cylindrical portion 30 forms a through hole 33 . Reference numeral 34 denotes a cutter that is rotatably disposed within the upper case 17, and its mounting base 35 is formed larger than the position where the locking hole 25 is disposed, and has a long length that is vertically connected to the mounting base 35. An elongated upper joint 36 is rotatably attached to the bulge 23. The lower joint 10 and the upper joint 36 are detachable and form a connecting member 37. A notch 37 is formed on the upper edge of the lower case 11 to allow the attachment portion 29 of the diffusion gutter 26 to escape. With the diffusion gutter 26 attached to the lower surface of the upper case 17, the sieve plate 20 facing the diffusion gutter 26 serves as a blind portion 20a. 39
The hot water supply has one end attached to the tank 2 via a check valve 40, a middle part wrapped around the heater 7, and the other end erected along the tank 2 to face the outside. It is a pipe, and the attachment part 29 of the diffusion gutter 26 is detachably attached to the other end of the pipe. To explain the operation of this configuration, water is stored in the tank 2, coffee beans are stored in the upper case 17, a timer switch (not shown) is operated, and the motor 3 is first energized to drive the cutter 34. The coffee beans are crushed by the rotation of the cutter 34 and the sieve plate 20, and become coffee powder through the through hole 19, which passes through the filter 1.
It will fall within 4. When the time has elapsed for the coffee beans to be almost completely ground, the power to the motor 3 is stopped, and then the heater 7 is powered to supply hot water to the diffusion gutter 26 through the hot water pipe 39 in a conventionally well-known drip method. . The hot water supplied to the diffusion gutter 26 is dripped onto the coffee powder from the water collection part 27 through the water sprinkling hole 32 of the water sprinkling part 28, and is passed through the filter 14.
The coffee liquid is filtered and supplied to the decanter 5 from the discharge hole 18 of the knob 13.

When the coffee beans are ground by the cutter 34, a force is applied to the coffee beans due to rotational centrifugal force so that they fly to the outer periphery instead of concentrating in the center.
The rotary crushed coffee beans do not collide with the locking pawl 31 of the diffusion gutter 26 that is protruding from the center of the sieve plate 20, thereby preventing the locking pawl 31 from being worn or damaged. can.

F. Effect of the invention Since the invention is constructed as described above,
It is possible to prevent the locking claws of the diffusion gutter attached to the lower surface of the sieve plate from being worn out or damaged.
