Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for grinding raw materials such as coffee beans,
The container is equipped with a basket capable of supplying and filtering hot water using a filter or the like, and a second basket capable of filtering things other than beans that do not require grinding, such as tea or ground coffee powder, and This invention relates to a beverage manufacturing machine equipped with means for supplying hot water to both baskets.

For example, the conditions for extracting delicious, flavorful coffee are to ``immediately pour boiling water over the coffee beans and filter them after grinding.''

Therefore, in order to obtain delicious coffee at home, it is necessary to have both a mill function for grinding beans and a drip function for dispensing hot water immediately after grinding.

The present invention has both of these functions, and is also capable of extracting products other than coffee, such as black tea, and fully responds to the diversification of consumer tastes in recent years.
In addition, the purpose is to rationally arrange the functions to make the device lighter and more compact.

Conventionally, a coffee boiler that has both the milling function and the dripping function has a drive motor, and the coffee machine is directly placed in a container that has a grinding body rotated by the motor and a filter that receives the powder obtained by grinding beans. There was a container for supplying hot water, and a container for brewing coffee, which had a separate bean grinding chamber and a container for supplying hot water and filtering the powder.

In either case, there are advantages and disadvantages, and both are used.

In the former method, which involves grinding beans in the same container, supplying hot water after grinding into the same container, mixing the powder and boiling water, and filtering, it is not possible to use fine-mesh paper filters, which have excellent filtration effects, as a filtration means. Moreover, even if it were used, it had the disadvantage that it could not be matched to the standardized shape of commercially available filters.
Therefore, a mesh-like net filter is used.

With this method, the size of the filter mesh is much larger than that of a paper filter, and the grinding roughness of the ground coffee becomes larger, so it is more difficult to obtain the desired coffee density than when using a paper filter. It was uneconomical because it required more beans, and on the other hand, if the same amount was used, it would result in an American-type extract with a lower concentration.
In addition, with this method, if the grinding time is too long, fine coarse coffee powder will be generated, which will pass through the holes in the filter mesh and enter the coffee storage cup, and the coffee extract containing the powder will be released. There are some drawbacks that can easily occur. Therefore, in this case,
The coffee liquid becomes cloudy, the coffee liquid accumulated in the storage cup is visually visible and gives an unpleasant feeling, and there is also the disadvantage that the taste feels rough when drinking.

However, in the coffee extraction process, the coffee is ground in the same container and hot water is immediately supplied, so there is no need to transfer the ground powder, which is convenient.
The big advantage is that the time required to extract the coffee is shortened by the time it takes to transfer the coffee.

As for cleaning up after use, it takes effort to wash out the inside of the container.

Next, if a bean grinding room and a powder filtration container are installed together, it will take time and effort to grind the beans to an appropriate degree of coarseness in the bean grinding room, and then transfer the powder to the filtration container. Although the advantage of the former has a disadvantage in terms of performance, a commercially available paper filter can be used as a filtration means.

Therefore, compared to the former method, sufficient components can be extracted from ground coffee powder and it is more economical. With the same usage amount, a highly concentrated coffee extract can be obtained,
It has a great filtration effect and produces clear coffee liquid. When it comes to cleaning up after use, it has the advantage that you can just throw away the paper filter.

In addition, the latter method has the advantage of having boiling water and residence time for tea leaves as extraction conditions for teas other than coffee, and immersing tea leaves in hot water for a predetermined period of time, and the latter method is optimal for extracting tea leaf components. It was hot.

The present invention has been made in view of the above circumstances, and includes a container body having a drive motor, and a grinding body for crushing raw materials such as coffee beans according to the rotation of the drive motor, and the crushed powder thereof. a basket having a filter for receiving the filter;
For example, each container is provided with a substantially inverted cone-shaped basket that houses a commercially available filter, and further includes a water storage tank and a heating section for heating the water supplied in the water storage tank, so that coffee powder and black tea can be heated. The system is equipped with a hot water supply device that selects and pours hot water into one of the baskets for storing leaves, etc., and improves the usability of coffee extraction, and creates a variety of flavors by creating concentration differences due to different filtration means. Furthermore, we aim to provide a beverage making machine that has the versatility of extracting tea, etc. other than coffee, and rationally arranges these functions in the same container to make the container lighter and more compact. It is something.

22 is a container top lid that covers the grinding basket 5 and filtration basket 14 side of the upper end opening of the container 1;
3 is a water storage tank lid. A thermostat 24 for temperature control is arranged at the outer bottom of the heating element 16.

Now, the electric circuit will be explained with reference to FIG.

31 and 32 are power terminals connected to, for example, a 100V single-phase AC power supply; 33 is a power switch;
4 is a changeover switch as an operation part, with a movable contact piece.
It has T ₁ and fixed contact pieces T ₂ and T ₃ .

35 is a safety switch, which is closed when, for example, the crushing basket 5 in the container 1 is assembled and the top lid 22 is securely closed.

A series circuit consisting of a power switch 33, contact pieces T ₁ and T ₂ of a changeover switch 34, a drive motor 3, and a safety switch 35 is connected between the power supply terminals 31 and 32. 34
The fixed contact piece _T3 connects the safety switch 35 through the sheathed heater 18 and thermostat 24 in series.
and the power supply terminal 32 are connected to a common connection point.

Next, the operation of this embodiment having the above configuration will be described. When grinding coffee beans and extracting coffee liquid (when performing extraction from grinding all the way without transferring coffee grounds), first, a predetermined amount of water is supplied into the water storage tank 26, and the grinding basket is Coffee beans as a raw material are put into the grinding basket 5, and the lid 10 is placed on the grinding basket 5 incorporating the mounting stand 8, and the substantially annular joint of the grinding body 6 is fitted into the rotating shaft of the drive motor 3. The hot water supply pipe 21 is set in the container 1 with the open end p of the hot water supply pipe 21 facing the heat diffusion part j, and the upper lid 22 is closed. Thus, the safety switch 35 is closed.

Further, by placing the glass container 12 with the lid 13 set on the heat insulating plate 17, the socket k of the glass container 12 faces the spout 11 of the grinding basket 5.

Therefore, the power switch 33 is closed, and further,
When the contact piece T ₁ -T ₂ of the changeover switch 34 of the operating section is closed, the drive motor 3 is energized, and the rotation of the rotating shaft 4 is transmitted to the crushing body 6 via the joint 9.

The coffee beans in the grinding basket 5 are crushed by the rotation of the grinding body 6, and are ground to an appropriate coarseness to become coffee powder.

Thereafter, when all the coffee beans have been ground to a suitable coarseness, the switch T ₁ -
When T ₃ is closed, the drive motor 3 is cut off due to the opening between contact piece T ₁ and _{T 3} and stops rotating.
By closing between T ₁ and T ₂ , the sheath heater 18 in the heating body 16 is energized and generates heat, and the heating pipe 19
Heat the water inside. Therefore, the water is heated in the heating pipe 19
The boiling water, that is, hot water, rises to the hot water supply pipe 21 side, drips from the opening end p of the pipe toward the grinding basket lid 10, is further diffused by the hot water diffusion part j, and flows into the hole i. By dripping the hot water onto the coffee powder in the basket 5, coffee components are extracted while the hot water passes through the coffee powder and passes through the filter 7, and the coffee liquid remains in the glass container 12 through the spout 11. .

Note that when the sheathed heater 18 generates heat, the lower surface of the glass container 12 is also heated via the heat insulating plate 17.

Furthermore, when the water is heated and boiled within the heating pipe 19, this boiling water tends to flow back toward the water storage tank 26, but this is prevented by the check valve 20 closing. Note that water is replenished into the heating pipe 19 based on the effect that the hot water in the heating pipe 19 is sent to the hot water supply pipe 21 side due to boiling pressure, and when the inside of the heating pipe 19 becomes negative pressure, the check valve 2
0 is opened, and the water in the water storage tank 26 is replenished into the heating pipe 19. In the same manner, all the water in the water storage tank 26 is continuously fed into the grinding basket 5 through the hot water supply pipe 21. The hot water is supplied as hot water, passes through the filter 7, and is stored in the glass container 12 through the spout 11 as coffee liquid.
Further, as long as the glass container 12 is placed on the heat insulating plate 17, the extracted coffee liquid receives power from the heating section 16 and is kept at an appropriate temperature by the thermostat 24.

Next, the case where the second filtration basket 14 is used will be explained.

After the coffee beans are ground in the grinding basket 5, the coffee powder is taken out and transferred to the second filtration basket 14.

The procedure is the same as described above, except that a predetermined amount of water and coffee beans are poured into the container 1, and the coffee beans are ground to an appropriate coarseness. After crushing the beans, turn off the power switch 33, close the contact piece of the changeover switch 34 to T ₁ - T ₃ , and close the top lid 22.
By opening the drive motor 3, the power is cut off and rotation stops. Thereafter, the coffee powder in the grinding basket 5 is transferred to a filtration basket 14 containing a paper filter 15 therein. This step is less operable than the extraction means described above.

Thereafter, the open end p of the hot water supply pipe is positioned and set toward the filtration basket 14 side, and the upper lid 2 is closed.

Next, when the power switch 33 is closed, the sheathed heater 18 is energized and generates heat, and the heating pipe 1
Heat the water in 9. The following steps are the same as the extraction method described above. However, the difference is that the hot water discharged from the hot water supply pipe 21 drips onto the coffee grounds in the filtration basket 14, passes through the basket small hole l, and accumulates in the glass container 12 from the socket n.

With the above method, although it takes time to transfer the coffee powder once, the coffee powder and hot water are filtered by the paper filter 15, so as mentioned above, the coffee powder and hot water are separated well, resulting in a clear and delicious coffee. It becomes a liquid. Moreover, it is convenient to clean up after use by simply discharging the used coffee powder together with the paper filter 15. In addition, it is also possible for the user to extract coffee using purchased coffee powder, but in this case, there is no need to grind it, and the coffee can be directly stored in the filter basket 14 and dripped.

Next, the case of extracting tea other than coffee will be described.

The conditions for black tea extraction are 3-4 tea leaves in boiling water.
It is said that unless the tea is steeped for a certain amount of time, the ingredients, aroma, and color of the black tea cannot be fully extracted. Actually, after putting the tea leaves into the grinding basket 5, turn on the power switch 33.
By closing contacts T ₁ - _{T 3} of the changeover switch 34 and dripping, hot water will not accumulate in the basket 5, the tea leaves will not be immersed in the hot water, and only black tea with a weak aroma can be extracted. . Therefore, it has been impossible to share coffee, tea, etc. extraction only with the same configuration using the grinding basket 5.

However, the present invention provides that the second filtration basket 14
If you brew black tea or the like, it can be handled by appropriately setting the diameter l of the small hole in the basket.

In other words, by allowing enough time for soaking tea leaves such as black tea in the hot water in the basket 14, the components of black tea etc. can be sufficiently extracted (fragrance, color, taste).

For the operation of brewing black tea, put only the required amount into the second filtration basket, put a predetermined amount of water into the water storage tank 26, rotate the hot water pipe tip p toward the second filtration basket 14, and turn on the power switch 33. , and then close the contact piece of the changeover switch 34.
When T ₁ to T ₃ are closed, the sheathed heater 18 is energized and generates heat, and the water in the water storage tank 26 is heated and poured into the filtration basket 14 through the hot water supply pipe 21. Black tea leaves, etc. are immersed in boiling water in the filter basket 14, which is set to allow the water to stay there for a required period of time, and the tea leaf components are sufficiently extracted.The aroma, color, and components are precipitated and then passed into the glass container 12 through the small hole L on the bottom surface. It accumulates in

Next, the arrangement will be explained. A pulverizing basket having a pulverizing body and a filtration basket storing a paper filter are arranged, and a basket is provided so that hot water can be poured into either basket by selection. In this method, hot water is poured from above both baskets, and the hot water supply pipe of the other rotating arm, which is attached at one end, is located directly above both baskets, which does not complicate the process.
The glass container is located close to the drive motor and below the filtration basket, and the glass container socket is near (directly below) the spout provided on the periphery of the crushing basket.
The other socket was also brought close to just below the filtration basket. Each is arranged in a compressed form on the same plane to simplify and compact the extraction configuration, and the water storage tank is placed on the opposite side of the filtration basket to the drive motor, so that its depth can be adjusted manually. It has a shape that extends in the longitudinal direction so that it can be carried around, and the water storage tank and tank lid are separated from the bean grinding section and the powder filtration basket section, so that it is easy to pour water into the water storage tank, preventing powder from getting into the water storage tank. It has a structure that can prevent it.

As described above, the present invention has a configuration that prevents the complication and enlargement of the vessel body in various configurations and makes it more compact and compact, and provides more beverage extraction functions in the same vessel, thereby making it easier for the user. The purpose of this invention is to provide a container that allows you to fully enjoy its ease of use and the fun of extracting it at your discretion.The effects of the present invention are listed below, and it is possible to achieve a more compact structure.

Considering operability, it is possible to extract by selecting either the convenience up to the extraction time or the ease of cleaning after use.

With the same amount of coffee used, thin and strong brewing functions are possible.

It is possible to extract tea leaves such as black tea.
