JP2518016Y2 - Coffee extractor for microwave oven - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is used to put coffee liquid into a microwave oven and heat the water by the microwave oven to extract coffee liquid easily in a short time. The present invention relates to a coffee extractor for a microwave oven.

[Conventional technology]

In recent years, the drinking population of coffee in Japan has been increasing more and more, but because the scent of coffee itself cannot be enjoyed with conventional instant coffee even at home or at work, the plastic has upper and lower filters, and Cartridge type sandwiching ground coffee powder between filters has become popular as a coffee extractor for a small number of people who can obtain a simple drip type coffee extract.

However, in this case, there is an unsatisfactory aspect in the coffee shop because the hot water of an appropriate temperature is required and the surroundings are open so that a full-scale extraction of the coffee liquid cannot be obtained.

Therefore, in recent years, a coffee maker has been developed in the United States and Japan that can easily extract non-instant regular coffee using microwave ovens, which are indispensable in the United States and Japan with high penetration rates.

An example of such a coffee maker is Japanese Patent Laid-Open No. 1-148212.
The invention relating to a method and a device for extracting beverages for microwave ovens is known, but in this case, the water in a container with a stopper lid is heated at high frequency, and the heated water in the container is siphoned by a curved pipe. Moreover, it is arranged in parallel to the water container and intermittently guides it into the filter containing the extract to perform extraction, and is of a siphon type, and the water container and the filter are Since they are installed side by side in the microwave oven, there is a problem that the installation space for the device is taken and the installation is troublesome.

Further, other conventional coffee makers for microwave ovens are also of the siphon type or the pumping system type as described above, and there is a problem that the structure thereof is not simple.

[Issues to be solved]

The present invention has been made in order to solve the above-mentioned conventional problems, and has a compact shape, a simple structure, and a coffee drip for a microwave oven, which can easily obtain a dripped coffee extract. The problem is to provide a container.

[Means for solving the problem]

As a means for solving the above problems, a coffee extractor for a microwave oven according to the present invention comprises a water tank portion with a lid,
The filtration basket part containing the coffee powder and the container for the coffee extract are provided in three layers from top to bottom, and the hot water injection path to the filtration basket part provided in the water tank part is opened by the pressure of boiling water. It consists of a microwave oven coffee extractor using a valve disc.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a cross section of a main portion of a coffee extractor for a microwave oven according to the embodiment of the present invention.

First of all, this extractor comprises a water tank part 2 having an easily removable lid 1 on the top, a filtration basket part 5 for containing coffee powder 3 and a cup-shaped container 7 of coffee extract 6 from top to bottom. A valve body 10 is provided in the hot water pouring path 8 to the filtration basket portion 5 provided in the central bottom portion of the water tank portion 2 which is provided in three stages, and the valve body 10 is always upward by the spring 12B. Since it is energized, the hot water injection passage 8 is closed.

Therefore, when the water 13 is injected into the water tank 2 of the coffee extractor, the valve body 10 for opening and closing the hot water injection passage 8 is
The hot water pouring path 8 is closed by the valve body 10 so that the spring 12B is biased upward and the water 13 in the water tank portion 2 does not drip.

In this embodiment, the lid 1 with the safety valve 15 is screwed into the water tank 2 through the seal packing 16A, and the water tank portion 2 is fitted through the seal packing 16B.

When the coffee extractor set as shown in Fig. 1 is placed in a microwave oven and energized to heat the water 13, the water boils,
Since the internal pressure of the water tank portion 2 rises, the valve body 10 pushes down the valve body 10 against the spring force of the spring 12B by the pressure to open the valve body 10 and taps hot water toward the filtration basket portion.

Then, the hot water passes through the coffee powder 3 all at once through the diffusion plate 18 in the filtration basket portion 5, and the coffee extract 6 is extracted.

The coffee powder 3 may be packed in any method such as a pack type coffee powder.

On the other hand, the container 7 can be made of pottery, magnetism, plastic, or the like, the seal packings 16A and 16B can be made of silicon rubber, and the spring material is generally made of stainless steel.

In this coffee extractor, since the pressure due to boiling is used, a rich coffee extract 6 such as an espresso type can be obtained at a high reaction rate and the extraction efficiency can be improved.

[Effect of device]

Since the coffee extractor for microwave oven of the present invention described above does not need to be equipped with heating means in the coffee extractor itself, it can be made inexpensively and compactly, and its shape is a three-tiered stacking form. Therefore, it has an effect that it has a shape that does not occupy the installation space and can be easily installed and handled in the microwave oven.

In addition, the reaction speed is faster than that of the conventional cartridge type, the extraction efficiency of coffee is increased, and a full-scale drip type regular coffee is obtained.

A particularly noticeable effect of the present invention is that a water tank part and a filtration basket part for putting coffee powder are separately provided on the upper and lower sides, and a valve body that opens a hot water injection path only when water boils, especially in the water tank part. Because the coffee powder is not mixed in the valve body and only the water enters, the valve body is not contaminated by the coffee powder, and it is necessary to frequently remove and clean the coffee powder inside the valve body. It has the effect that it can always be used in a clean state.
