Description

[Detailed Description of the Invention] The present invention relates to a drip type coffee brewer in which a filter cup can be attached and detached in the vertical direction, and more particularly to a coffee brewer in which the structure of the hot water supply pipe is simplified and the filter cup can be easily attached and detached.

Conventionally, in coffee brewers, a hot water supply pipe is generally installed from the heating section along a funnel-shaped or bottomed cylindrical filter cup, and a hot water supply port is located at the upper end of the hot water pipe, facing the top of the filter cup. The hot water supply pipe is constructed so that the hot water supply port can be rotated horizontally or vertically so as not to interfere with the vertical attachment and detachment of the filter cup.

For this reason, the coffee extractor has the drawback that, in addition to the complicated structure of the hot water supply pipe, hot water may leak from the rotating joint of the hot water supply pipe.

This invention was devised to eliminate the above-mentioned drawbacks,
The purpose of this is to simplify the structure by molding the hot water supply pipe with a flexible material, so that hot water can be reliably supplied to the hot water supply part of the filter cup without any leakage, and the hot water supply pipe can be moved when the filter cup is attached or removed. To provide a coffee extractor that is easy to operate and can be manufactured at low cost.

A preferred embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a drip type coffee extractor having a drip function and a mill function, and this coffee extractor 1 has a water storage tank 2 above and a filter cup storage chamber 3 arranged in parallel with the water storage tank 2.

The filter cup storage chamber 3 has a coffee liquid outflow hole 3a on the bottom wall.
is formed, and integrally has a motor chamber 4 below.

A vertical shaft motor (not shown) is provided in the motor chamber 4,
The rotation shaft 5 of this vertical axis motor penetrates the bottom wall of the filter cup storage chamber 3 in a liquid-tight manner and projects into the filter cup storage chamber 3.

Inside the filter cup storage chamber 3, there is a cylindrical filter cup 6 with a bottom, and the rotation shaft 5 of the vertical axis motor is attached to the center of the bottom wall of the filter cup 6.
The filter cup storage chamber 3 is removably housed in the upper end opening of the filter cup storage chamber 3 by loosely fitting and protruding therefrom.

The filter cup 6 has a bottom wall having a plurality of through holes 7 and a filter 8 stretched thereon, and a support piece 6a for supporting the filter cup in the filter cup storage chamber 3 is integrally formed on the outer peripheral wall.

Further, a filter cover 10 having a hot water pan 9 is detachably attached to the upper opening of the filter cup, and a mill cutter 11 is attached to the rotary shaft 5 protruding from the center of the bottom wall.

A heating chamber 12, which is a heating section, is provided in the lower part of the motor chamber 4, and a coffee cup 14 is placed on a coffee cup mounting table 13 of this heating chamber 12 with its opening positioned in the coffee outflow hole 3a. It is placed.

A heater 15 is disposed inside the heating chamber 12, which warms the coffee cup, heats water led from the water storage tank 2 through a water conduit (not shown), and sends the heated hot water to the hot water base pipe 16. is configured to do so.

The hot water supply base pipe 16 is connected from the heating chamber 12 to the filter cup storage chamber 3.
It is erected near the bottom wall, and a hot water supply pipe 17 made of a flexible member is connected to its upper end.

This hot water pipe 17 is connected to a gap S formed between an inner wall 2a of the water storage tank 2 and an inner wall 3b of the filter cup storage chamber 3.
1 and is erected along the filter cup 6.

That is, the upper end of the hot water supply pipe 17 is bent so as to face the hot water receiver 9 of the filter cup 6 and forms a hot water supply nozzle part 18, and the hot water supply pipe 17 is spaced outward from the filter cup 6 at the bent part. An operating knob 19 is integrally formed therein.

Further, the outer part of the hot water supply pipe 19 is connected to the inner wall 2a of the water storage tank 2.
The hot water supply nozzle portion 18 is urged in the direction of the hot water receiving portion 9 of the filter cup 6 by being pressed by a leaf spring 20 which is a biasing means provided in the filter cup 6 .

Note that 21 in the figure is an upper lid that covers the water storage tank 2 and the filter cup storage chamber 3.

The operation of the present invention having the above configuration will be described.

From the water storage tank 2 to the heating chamber 12 via a water pipe (not shown)
The water is heated by the heater 15, and the hot water rises along the hot water base pipe 16 and the hot water pipe 17, and flows from the hot water nozzle part 18 to the filter cover 1 in the filter cup 6.
The hot water is spouted to the hot water receiving part 9 of 0.

When such hot water is injected, the hot water supply pipe 17 has an integral pipe structure, so there is no possibility of hot water leaking.

Moreover, since the hot water supply pipe 17 is formed of a flexible member,
When attaching and detaching the filter cup 6, the hot water supply nozzle portion 18 of the hot water supply pipe 17 can be moved outward from the filter cup 6 using the operation knob 19, thereby making it possible to easily attach and detach the filter cup 6.

Furthermore, the hot water supply pipe 17 is equipped with a plate spring 20 on the outside for heat resistance in the direction of the filter cup, so once the filter cup 6 is installed, if the operating knob 19 is released, the force of the plate spring 20 will automatically release the filter cup 6. A hot water nozzle portion 18 of the hot water supply pipe 17 faces the hot water receiving portion 9 of the filter cover 10 in the filter cup 6.

This ensures that coffee brewing errors due to forgetting to operate the hot water pipe never occur.

In the above embodiment, the present invention is applied to a device having a drip function and a mill function, but it is of course applicable to a device having only a drip function.

In summary, the present invention provides the following effects.

■ Since the hot water supply pipe and the hot water supply nozzle are generally made of flexible materials, there is no leakage of hot water at all.

(2) Moreover, the hot water supply pipe can be easily moved when attaching and detaching the filter cup.

■ It has a simple structure and can be provided at a low price.
