Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a coffee maker for brewing coffee in a drip style using a microwave oven.

(Prior Art) The popularity of microwave ovens has been remarkable in recent years, and a wide variety of microwave foods and microwave cookers are now on the market, but there is no device for directly brewing coffee using a microwave oven. , it is simply used to reheat already brewed coffee. What's more, when you do this, the flavor is significantly impaired compared to when it's freshly brewed.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to provide a microwave coffee maker that can easily extract a certain amount of delicious coffee using a microwave oven.

(Means for solving the problem) In this invention, in order to solve the above problem,
A cup 1 that receives extracted coffee, a metal dripper 3 that accommodates coffee powder C and is placed on the cup 1, and a metal water separator that covers the top of the dripper 3 and blocks microwaves. The water heater 4 includes a microwave shielding member such as 5 and a non-metallic water heater 4 that stores a certain amount of water and is placed on the dripper 3. An outflow pipe 4c, which is located slightly above the water surface and whose lower end outlet is located below the bottom of the water heater 4, is installed so as to vertically penetrate the bottom plate. A cap 6 is inserted leaving a water flow gap between the bottom of the boiler 4 and the outer periphery of the outflow pipe 4c, and a small space S is formed above the outflow pipe 4c inside the cap 6. A microwave coffee maker was configured as described above.

(Function) When making coffee using the microwave coffee maker of the present invention, put coffee powder C into the dripper 3 equipped with the filter F,
A water heater 4 containing a certain amount of water is placed on top of it. Note that the outflow pipe 4c in the water heater 4 is covered with a cap, and a microwave shielding member such as a metal water divider 5 is attached to the lower part of the water heater 4. Then, place these on top of the cup and heat in the microwave. At this time, since the metal water separator 5 and the metal dripper 3 shield microwaves, the coffee powder C is not heated, and therefore the flavor is not impaired. When the water in the water heater 4 boils due to microwave irradiation, the outflow pipe 4
Boiling water splashes into c or water vapor condenses, blocking the outflow pipe 4 and water-shielding the inside thereof. By stopping the microwave irradiation, the space S
When the temperature drops slightly, the water vapor inside condenses, creating negative pressure. Then, the hot water in the cap 6 rises into the space S and flows into the outflow pipe 4c,
Using the principle of a siphon tube, the water flows down to the water divider 5 at once, where it is divided in all directions and further dripped into the dripper 3. Coffee is extracted by the dripper 3 and stored in the cup 1.

In FIG. 1, 1 is a heat-resistant glass cup with a handle. Cup 1 is placed on cork tray 2 when drinking. A metal dripper 3 is placed on top of the cup 1.

As shown in FIGS. 3A and 3B, the dripper 3 is
It is a nearly cup-shaped metal container, and the lower part thereof is provided with a small diameter portion 3a that is reduced in steps. Then, this small diameter portion 3a can be fitted into the cup. The bottom surface of the dripper 3 is inclined slightly downward toward the central drip hole 3b, and has numerous protrusions 3c over its entire surface.
is provided. An annular handle 3d made of synthetic resin is attached to the upper outer periphery of the dripper 3.

As shown in FIGS. 4A and 4B, the water heater 4 is also a substantially cup-shaped container made of synthetic resin, and is provided with a reduced diameter portion 4a formed in steps at the bottom. This small diameter portion 4a can be fitted into the dripper 3. An engaging protrusion 4b for screwing the water divider 5 is provided on the outer periphery of the small diameter portion 4a. The bottom of the water heater 4 is sloped slightly downward toward the center.
An outflow pipe 4c is integrally installed in the center. The lower end of the outflow pipe 4c slightly protrudes downward from the lower surface of the water heater 4, and the upper end is located slightly above a reference water level line 4d provided on the upper inner peripheral surface of the water heater 4. Three receiving seats 4e for supporting the cap 6 are provided at intervals on the lower outer periphery of the outflow pipe 4c.

As shown in FIGS. 5A and 5B, the water separator 5 is a metal dish-shaped container. At the center of the bottom of the water separator 5,
A water reservoir recess 5a is provided, and a large number of water diversion holes 5b are provided over the entire bottom surface. Further, on the inner periphery of the water divider 5, an engaging protrusion 5c for screwing into the small diameter portion 4 of the water heater 4 is provided. When screwed into the lower part of the water heater 4, the lower end of the outflow pipe 4c enters the water reservoir recess 5a.

As shown in FIGS. 6A and 6B, the cap 6 includes a cylindrical main body 6a with a closed upper end, and three radially extending parts on the outside of the main body 6a at a mutual interval of 120 degrees.
and two partition plates 6b. This partition plate 6b is attached to the water heater 4 when it is installed inside the container 4.
Divide the inside into three. The cap 6 has a length such that a space S is formed between it and the upper end of the outflow pipe 4c when the cap 6 is placed on the receiving seat 4e.

The lid 7 is placed over the water heater 4 when not in use, and also serves as a receiving tray for the dripper 3 after use.

Next, the operation of the above embodiment will be explained. To extract coffee with this coffee maker, first place a circular filter F on the bottom of the dripper 3.
Add an appropriate amount of coffee powder C on top of it, and with the cap 6 attached to the outflow pipe 4c in the water heater 4 and the water divider 5 attached to its lower part, add water up to the reference water level line 4d. Set as shown in FIG. Then, put it in the microwave and heat it by irradiating it with microwaves. During heating, the metal water separator 5 and dripper 3 shield microwaves, so the coffee powder C inside is not heated, and only the water in the water heater 4 is heated. Due to the action of the partition plate 6b, the temperature increasing portions within the water heater 4 are dispersed, so that uneven heating does not occur and the entire water heater is heated in a short time. When the water in the water heater 4 boils due to microwave irradiation, the boiling water splashes into the outflow pipe 4c.
The water vapor condenses and blocks the outflow pipe 4, thereby water-shielding the inside thereof. When the temperature of the space S inside the cap drops slightly due to the stop of microwave irradiation, the water vapor inside the cap condenses, creating a negative pressure, and hot water rises inside the space S. Then, the hot water in the cap 6 flows into the outflow pipe 4c and falls all at once to the water divider 5 according to the principle of a siphon pipe, where it is divided in all directions and further dripped into the dripper 3. Coffee is extracted by the dripper 3 and stored in the cup 1. The lower end of the outflow pipe 4 is
Since the water droplet is located in the water reservoir recess 5a of the water divider 5, when water droplets initially formed in the outflow pipe 4c flow down, they accumulate in the water reservoir recess 5a and block the lower end of the outflow pipe 4. Therefore, the outflow pipe 4 is reliably water shielded. If the inner diameter of the outflow pipe 4c is too large, the water shield phenomenon will not occur. Therefore, it is necessary to select an appropriate amount within a range that does not interfere with the water shield phenomenon.

Although not shown, a dripper 3, a water divider 5
can be made of synthetic resin with a microwave-impermeable metal coating, and a separate microwave shielding member can be provided instead of the water divider 5 to cover the dripper 3. can. Further, the cap 6 may be constructed integrally with the water heater 4.

(Effects of the invention) As described above, the invention includes a cup 1 that receives extracted coffee, a metal dripper 3 that accommodates coffee powder C and is placed on the cup 1, and a metal dripper 3 that accommodates coffee powder C and is placed on the cup 1. It is equipped with a microwave shielding member such as a metal water divider 5 that covers the top and blocks microwaves, and a non-metallic water heater 4 that stores a certain amount of water and is placed on the dripper 3. ,
Inside the water heater 4, an outflow pipe 4c having an inlet at the upper end located slightly above the water surface and an outlet at the lower end located below the bottom of the water heater 4 vertically penetrates the bottom plate. A cap 6 is inserted into the outflow pipe 4c, leaving a water flow gap between the bottom of the water heater 4 and the outer periphery of the outflow pipe 4c. Since the microwave coffee maker is configured such that a small space S is formed in the upper part of the pipe 4c, coffee can be easily extracted in a microwave oven without spoiling the flavor. has.
