Description

[Detailed Description of the Invention] The present invention relates to a filtration device for a coffee boiler, and is particularly aimed at improving operability.

Conventionally, the coffee basket in a drip-type coffee boiler is made of synthetic resin or the like and is formed into an approximately inverted conical shape, and its inner surface has multiple ribs that guide the coffee that has passed through the paper filter to the bottom. It consists of a filter body each equipped with an outlet and a support frame surrounding the filter body, and is only placed in a container that receives the coffee filtered by the filter body, and has poor stability, such as a support frame surrounding the filter body. Sufficient care was required when installing and moving the boiler.

Furthermore, during coffee extraction and when keeping the coffee warm after coffee extraction, water droplets condensed on the back of the coffee basket were transmitted to the outer periphery of the coffee container, staining tablecloths and other rugs, and often damaging the appearance.

Furthermore, when pouring into individual coffee cups,
The coffee basket had to be removed from the coffee container and poured, which was time-consuming and undesirably lowered the temperature of the coffee.

The present invention solves the drawbacks of the conventional coffee filtration device, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 to 3, 1 is a water tank, which has a lid 2 at its upper opening and a check valve 3 at its bottom.

4 is a heating pipe, one end of which is connected to the water tank 1 through a check valve 3, and the other end connected to a discharge vibro through a water rising pipe 5.

This discharge vibro is provided with openings 6a and 6b above the coffee basket 7.

The coffee basket 7 includes a filter main body 8 having a substantially inverted conical shape,
It consists of a cylindrical support frame 9 surrounding this filter body 8, and is integrally formed of synthetic resin or the like.

A plurality of ribs are formed on the inner surface of the filter body 8, and a coffee outlet 10 is provided at the bottom.

Coffee powder 12 is stored in this filter body 8 via a paper filter 11.

Reference numeral 13 designates a coffee container on which the coffee basket 7 is placed and which receives the coffee filtered by the filter body 8. A spout 14 is formed at the upper end, and a handle 15 is attached to the outer surface. .

An annular collar 9a having a diameter slightly larger than the diameter of the support frame 9 is formed at the lower part of the support frame 9 of the coffee basket 7, and the coffee receiver engages with the upper end of the container 13 and the outer surface of the upper end.

Further, the flange portion 9a is formed with a notch portion 9b that engages with a spout 14 provided in the coffee container 13, and a handle 9C that engages with a handle 15.
However, the coffee tray is placed in engagement with the container 13 and positioned to prevent rotation.

Furthermore, an annular protrusion 9d extending from the lower end of the support frame 9 is inscribed in the upper end of the coffee container 13.

A heating element 16 for heating the coffee container 13 via a heat insulating plate 11 is provided below the coffee container 13, with a heating pipe 4 and a sheathed heater 17 installed therein.

In the above configuration, water in the water tank 1 flows into the heating pipe 4 through the check valve 3.

The check valve 3 allows the water in the water tank 1 to pass into the heating pipe 4, but does not allow it to pass in the opposite direction.
The water inside is heated by the sheathed heater 17 via the heating element 16, expands and boils repeatedly, and is discharged from the opening 6 of the vibro discharger.
The coffee powder 12 in the coffee basket 7 is ejected from the coffee cup 7a and 6b, and the coffee liquid is gradually extracted into the coffee container 13 by being filtered by the coffee basket 7.

When the extraction is completed, the temperature is automatically maintained by a thermostat (not shown) provided in the heating element 16.

In this case, water droplets condense on the back surface of the coffee basket 7, and the water droplets condensed on the back surface of the filter main body 8, which has an approximately inverted conical shape, are guided to the lower center of the filter body 8, and the coffee receiver drips into the container 13. Further, water droplets condensed on the back surface of the vertical wall of the cylindrical support frame 9 flow down to the lower end, and the coffee receiver drips into the container 13 from the protrusion 9d.

Furthermore, when pouring into each coffee cup, the coffee basket 7 has an annular brim 9 formed at its lower end.
The coffee receiver a is engaged with the outer surface of the upper end of the container 13, and the coffee receiver can also hold the handle 9C of the coffee basket 7 at the same time as holding the handle 15 of the container 13, so that the coffee basket 7 With the coffee placed on it, the coffee receiver can be poured directly from the spout 14 of the container 13 and the notch 9b of the coffee basket 7. As a result, the temperature of the coffee does not drop and its usability is improved. It will improve.

In addition, even when moving the container 13 of a coffee boiler or a coffee tray with the coffee basket 7 placed thereon, the coffee basket 7 is securely placed on the container 13.
Usability and safety can be improved.

Further, as described above, the coffee basket 7 is formed in a substantially M-shaped longitudinal section, and has an annular collar 9 on the outer periphery of the lower end.
a, the mold for molding the coffee basket 7 can be divided into two sides, which not only improves productivity, but also supports the coffee filtered in the filter body 8. The two walls of the frame 9 and the filter body 8 are isolated from the outside air, and the air layer between the support frame 9 and the filter body 8 is heated by the finished coffee in the container 13, so the coffee tray is heated by the finished coffee in the container 13, so it is insulated from the outside air. It has high heat retention and therefore enables ideal coffee filtration.

As described above, according to the present invention, a coffee basket is constructed by a filter main body having a substantially inverted conical shape and a cylindrical support frame surrounding the filter main body, and a coffee tray is provided at the lower end of the support frame. Since an annular protrusion is formed in the upper end of the container, water droplets condensed on the back side of the filter body that make up the coffee basket drip into the container along the sloped surface of the filter body. In addition, water droplets that have condensed on the back side of the support frame will flow down to the bottom edge, and drip into the coffee container from the protrusion, which will not stain the tablecloth or other rugs or spoil the appearance. There will be no loss.

Further, at the lower end of the support frame, the coffee tray further has an annular collar that engages with the upper end of the container and the outer surface of the upper end. The coffee basket can be reliably placed in a stable state on the coffee container, so even when moving the coffee filtration device, it can be moved in a stable state. The receiver can heat the back side of the filter body by the coffee in the container, and by providing a cylindrical support frame that surrounds the filter body, it becomes a two-layer wall, so it is also isolated from the outside air. As a result, insulation and heat retention become reliable, and ideal coffee filtration conditions can be created, which is a practical effect.
