Description

[Detailed Description of the Invention] The present invention relates to a drip-type coffee boiler that keeps a coffee liquid storage bottle molded from plastic or other resin warm.

To explain the conventional drip type coffee boiler from the side view in Fig. 1, the drip type coffee boiler whose side surface is approximately U-shaped has a water tank 2 on one side of the base 1. A water pipe 3 is arranged from the bottom of the tank 2 into the base 1, and this water pipe 3
The other end is connected to a hot plate 4 in the base 1 which is provided with a heater and a hot water conduit 5, which extends upward from the hot plate 4 and is placed on the base 1 for a coffee liquid reservoir. It is bent at the upper blade of the bottle 6.

The bottle 6 also has a filter 7 for storing coffee powder and a hot water diffusion lid 8 on the filter 7, and the hot water discharge port 9 of the hot water conduit 5 is located above the hot water diffusion lid 8. be.

In the above-mentioned drip type coffee boiler, the hot water in the hot water conduit 5 heated by the heater of the hot plate 4 is heated by the hot water conduit 5 because a check valve is interposed between the water tank 2 and the water conduit 3. The sitz bath discharged from the discharge port 9 is diffused by a hot water diffusion M8, passes through a filter 7 containing coffee powder, and stores coffee liquid in a bottle 6.

As shown in FIG. 2, the hot plate 4 has a heater 10 and a hot water conduit 5 fixed to a metal plate such as an aluminum plate by casting or crimping, as in a sheathed heater, and as shown in FIG. 3, a side sectional view of the base part. A heat insulating plate 12 made of an aluminum plate is provided from the inside of the base 1 through a waterproof packing 11 such as a silicon packing so as to close the opening on the top surface of the base 1, and a heat plate 4 is placed on the surface of this heat insulating plate 12. In addition, the metal fittings 14 are fixed to appropriately selected locations on the base 1 with screws 13 via the metal fittings 14 so as to press the hot plate 4 toward the upper surface of the base 1.

In the conventional example shown in FIG. 3, the heater 10 and the hot water conduit 5 are shown molded by casting.

As described above, in the conventional drip coffee boiler, since the bottle 6 is made of glass or porcelain, it is possible to keep warm by the heat transmitted from the heating plate 4 to the heat insulating plate 12. However, the bottle 6 is made of plastic or paper. When using the hot plate 4, since the heat transmitted from the hot plate 4 is high temperature, at least the bottom surface of the bottle 6 in contact with the heat retaining plate 12 is deformed and discolored.

In addition, a waterproof packing 11 is required to prevent insulation deterioration due to water intrusion or seepage into the interior, which, along with glass or porcelain bottles, is expensive and the manufacturing process is complicated.

The present invention relates to a drip-type coffee boiler devised in view of the above points, and uses a bottle 6 made of inexpensive resin such as plastic to simplify the manufacturing process of the drip-type coffee boiler.

The present invention will be explained below based on examples.

Fig. 4 is a sectional view of the base side of a drip coffee boiler similar to the conventional example, and the same elements as those shown in Figs. 1 to 3 will be explained using the same numerals. Then, a bottle positioning part 15 is provided on the top surface of the base 1 in which the bottom surface of the resin bottle 6 is positioned, and the base 1 bottle positioning part 15 in the base 1 is provided.
A hot plate 4 is provided at the portion with a heat insulating material 16 in between.

As the heat insulating material 16, for example, a mica plate or glass wool is used.

The hot plate 4 equipped with the heater 10 and the hot water conduit 5 has a metal fitting 14
is pressed against the top surface of the base 1, and one end of the metal fitting 14 is pressed against the top surface of the base 1.
It is fixed with screw 13 to the continuous feeding point.

As described above, the drip-type coffee boiler of the present invention limits the conduction heat from the hot plate 4 so as to maintain the surface temperature of the base 1 at around 120°C to 130°C, thereby heating the resin bottle 6. It can be kept warm and is cheaper than a glass or porcelain bottle 6.
1 is no longer required, and the assembly man-hours can be simplified.
