Description

DETAILED DESCRIPTION OF THE INVENTION B. Field of Industrial Application The present invention relates to a coffee boiler that can consistently perform the process from pulverizing coffee beans to supplying hot water to the ground coffee powder.

B. Prior art In the conventional coffee boiler that extracts coffee liquid through an integrated operation from grinding to hot water supply, hot water is supplied from above the blade 4, as can be seen in JP-A-55-108333. As a result, these blades may get in the way and prevent hot water from being evenly supplied to the entire area, or hot water may enter through the attachment part of the blade 4 and have an adverse effect on the electric motor 1, or when the coffee beans are ground due to the rotation of the blade 4. However, there was a drawback that the first filter 7 was bent downward due to the pressure of the coffee beans, resulting in a reduction in the grinding ability and damage.

C. Purpose of the invention The present invention is to use a diffusion gutter to both reinforce the sieve plate placed below the cutter and diffuse hot water, and to extract flavorful coffee liquid by efficiently supplying hot water. With the goal.

○D Structure of the Invention The present invention engages an upper case which has a cutter rotatably and is provided with a sieve plate with a large number of through holes in its bottom surface, and a lower case which has a filter arranged in its bottom surface. , and a diffusion gutter to which hot water is supplied is brought into abutting engagement with the lower surface of the sieve plate.

○E Embodiment 1 of the invention 1 is a main body of a coffee boiler, and the top surface has a tank 2 for storing water and a mounting base 4 in which a motor 3 is installed.
and a placing section 6 on which the decanter 5 is placed. The placing portion 6 exposes a heater 7 so that the decanter 5 can be placed directly on the heater 7. The decanter 5 has a handle 8 attached to its outer surface and a lid 9 with a partially opened upper surface. The motor 3 has a lower joint 10 slightly protruding from the upper surface of the mounting base 4. Reference numeral 11 denotes a lower case that is detachably placed 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 has a discharge hole 18 facing the upper opening of the decanter 5 and communicates with the inside of the lower case 11. Reference numeral 14 denotes a filter that can be attached to and removed from the lower case 11, and has a cylindrical shape with an open top, and a cylindrical portion 15 that covers the protruding portion 12 from the periphery is formed approximately at the center of the bottom surface. The protrusion 1
2, and this cylindrical portion 15 is a blind portion as shown. The bottom and side surfaces of the filter 14 are mesh-shaped, and reinforcing bars 16 are provided here and there. Reference numeral 17 denotes a cylindrical upper case that can be attached to and removed from the upper surface of the lower case 11. A sieve plate 20 with a plurality of through holes 19 is provided in the bottom surface, and a suction hole 21 is formed in the opening of the upper surface. The installed cover plate 22 is detachable. The center of the sieve plate 20 is slightly bulged upward to form a bulge 23, and 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. Reference numeral 26 denotes a diffusion bucket that is attached to and detached from the lower surface of the upper case 17, and includes a circular water collecting portion 27 and four water sprinkling portions 28 extending radially from the water collecting portion 27.
It is composed of a substantially L-shaped mounting portion 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 3
6, and the two form a connecting member 37. A notch 3 is provided at the upper edge of the lower case 11 to allow the attachment portion 29 of the diffusion gutter 26 to escape.
7 is formed. The diffusion gutter 26 is connected to the upper case 1.
The sieve plate 20 facing the diffusion gutter 26 when attached to the lower surface of the sieve plate 7 is a blind portion 20a. The diffusion gutter 26 is in contact with the lower surface of the sieve plate 20. 39 has one end attached to the tank 2 via a check valve 40, the middle part wrapped around the heater 7, and the other end erected along the tank 2 to face the outside. The other end of the hot water supply pipe has a mounting portion 29 of the diffusion gutter 26 located opposite to it.

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 are dropped into the filter 14 as coffee powder through the through hole 19. 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 supply pipe 39 in a conventionally well-known drip method. . The hot water supplied to the diffusion gutter 26 is dripped from the water collection part 27 through the water sprinkling hole 32 of the water sprinkling part 28 onto the coffee powder, filtered by the filter 14, and turned into coffee liquid, which is then turned into the knob 1.
It is supplied to the decanter 5 from the discharge hole 18 of No. 3.

Effects of the invention According to this configuration, the coffee beans are ground by the cutter and the sieve plate, so the filter is not clogged with ground coffee powder as in the conventional case, and the diffusion gutter is not used for the sieve. Since it is in contact with the lower surface of the plate, this diffusion gutter acts as a reinforcing member to prevent deformation and damage of the sieve plate during grinding of coffee beans. Furthermore, since the upper surface of the lower case from which the coffee liquid is extracted is covered by the upper case, delicious coffee liquid can be supplied to the decanter without the flavor escaping.
