Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a machine for brewing beverages such as coffee.

Conventional configurations and their problems Traditionally, when making coffee at home, water was injected into an extractor such as a drip type, siphon type, or percolator, and the power switch was operated.
The extractor was heated to boiling water, and coffee was extracted using the boiling water.

For this reason, the preparation work before brewing the coffee is troublesome and the preparation time is required, and since the extractor is configured to boil cold water, the coffee extraction time is the time required to boil the water. However, when the user wants to drink coffee or for unexpected entertainment, it is not possible to brew coffee immediately and easily. In addition, the conditions for extracting flavorful and delicious coffee are generally referred to as f-high temperature (91-96% ℃) for a short period of time (3~4℃)
It is "extracting in minutes)".

However, it takes 10 to 12 minutes to extract 6 cups (660 cc of water) of coffee liquid with a power consumption of 500 W, and the extraction temperature is also slow because boiling water is discharged containing cold water. Drip type, which uses a low temperature of 80-86℃, and siphon type, which takes less than 1 minute to extract even with boiling water, effectively extract the flavorful active ingredients contained in coffee grounds. It is not something that can be extracted exactly, and the extraction time varies from the maximum cup (6 cups) to the minimum cup (1 cup).
It has not been possible to extract a stable and delicious coffee liquid by further complicating the above extraction conditions. Therefore, in order to enhance the taste and aroma of coffee, it is possible to compensate for this point by increasing the amount of coffee powder, but this will require a longer brewing time. In addition, it was uneconomical, and the coffee tended to be too strong and taste bad.

In addition, there were many problems with the structure of the aircraft, such as the operation of inserting and removing the coffee liquid storage cup when drinking coffee and cleaning up after use, and there were problems that needed to be improved.

In addition to the above-mentioned household brewing method, there is a hot water storage expulsion type coffee extractor for commercial use for the purpose of brewing a large amount of coffee.

This is heated in advance with a heater and stored in a container, and when necessary, the same amount of water as the amount to be extracted is poured from the top of the container, and the water in the container is pushed out in a sealed form. , the stored hot water is discharged by the siphon effect and poured into coffee powder prepared in a basket to extract coffee.

However, since the hot water in the container is forced out by injecting water,
When the hot water (96-98℃) is cooled by water and comes into contact with coffee grounds, 10 cups (depending on the amount of boiling water and the amount of water poured) in a regular 2.6Q container (
1 soocc) has the drawback that the temperature drops to around 88℃ when extracted, and there is a limit to the amount of water that can be extracted, and less than 3 cups (400cc) cannot be discharged, so it is limited to some commercial use and for general household use. It has not been adopted as such.

In addition, a preparatory operation for injecting water is required, and the hot water dispensing time is not constant, and the dispensing time is about twice as long for 6 cups and 10 cups, which is the 3 to 4 cup time required for brewing delicious and flavorful coffee. It is not possible to ensure a consistent brewing time, resulting in differences in the aroma and taste of the extracted coffee. In addition, since the container has a nearly airtight structure with a lid except for the injection tube of approximately 12φ, cleaning the inside of the container is not possible, and if the container is used for a long period of time, water scale, rust, and impurities may form inside the container. Sometimes they were expelled along with hot water, inhibiting the extraction of the coffee's active ingredients and making the coffee taste unpleasant.

Purpose of the Invention The present invention was made in view of the above circumstances.The purpose of the present invention is to easily extract coffee in a short time with a simple operation without having to pour water into the machine each time the coffee is extracted. It satisfies the requirements of short-time brewing at high temperatures and can be extracted as a delicious, flavorful coffee liquid. It also improves the operability of the machine, and can be easily disposed of after use, making it hygienic to use. It is an object of the present invention to provide a highly versatile beverage brewing machine that can extract coffee from a small cup to a large capacity without being limited to the amount of coffee extracted.

Structure of the Invention In order to achieve the above object, the beverage brewing machine of the present invention includes a hot water storage tank having a heat retention function that can keep hot water warm, a hot water storage case equipped with a valve function, and raw materials such as coffee powder, Further, by providing a filter case for extracting a beverage with hot water from the hot water storage case, a cup for receiving the beverage from the filter case, and a water supply device for supplying hot water from the hot water storage tank to the hot water storage case. , it is possible to constantly store hot water at a high temperature, and when you want to drink coffee, you can use the stored hot water to brew coffee without having to pour water into the machine, making it easy to operate and brew in a short time. Since high-temperature boiling water comes into contact with the coffee powder, you can drink a rich and delicious coffee liquid, and the extraction conditions can always be set the same, and the operability and post-processing after use are easy. It has various excellent features such as being easy to carry out.

1, and is made of a good thermal conductor (made of aluminum, for example) that transmits the heat from the cup heater 84 on the back side to the cup 76 from the lower bottom surface.The temperature is controlled by energizing the cup heater 84. This is done by a thermostat 86 for keeping the cup warm.

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

91 and 92 are power terminals connected to, for example, a 1 oov single-phase AC power supply; 93 is a power switch (operation button 94 is shown in FIG. 1);
is connected to the other end power terminal 92 via a protective temperature fuse 97 (tank water boiling heater 11 and thermostat 19 connected in series to A and C), and tank heat retention heater 12 and TR320 Furthermore, a cup heat keeping switch 95 (an operation button 96 is shown in FIG. 1), a cup heat keeping heater 84, and a cup heat keeping thermostat 86 are connected in parallel.

Reference numerals 98 and 99 indicate a water boiling indicator lamp and a heat preservation indicator lamp, which are linked to heat generation and stoppage of the tank water heater 11 and indicate the water heating and heat retention status of the hot water storage tank 10, and their common contact points are connected to 8 points between the tank water heater 11 and the thermostat 19. The other contact of the boiling water indicator lamp 98 is placed at point A on the power terminal side, and the other contact of the heat retention indicator lamp 99 is placed on the power terminal 92 side (contact C side). Reference numeral 100 designates a cup heat retention indicator lamp that is turned on when the cup heat retention switch 95 is closed, and is connected between a terminal connected to the cup heat retention switch 96 and a contact C of the power supply terminal 92.

Next, the operation of the above configuration will be explained.

First, when the lid 30 is pushed up with the knob 42 by hand and the one claw 43 is disengaged from the fitting hole 44 of the upper wall recess 16, the lid 30 rotates about the protruding retaining part 40 as a fulcrum. and can be removed from fuselage 1.

Then, water is injected into the hot water storage tank 10 using a jug or other jug, but at this time there is no need to take out the inner lid 21, and even if the injection position shifts or if the inner lid 21 protrudes and splashes, The inner surface of the earthen wall part 4 and the recessed part 15 acts as a water shield to prevent the outside of the machine from getting wet. Moreover, since the inclined surface a of the injection guide plate 22 works to smoothly guide the scattered water toward the injection port 28, the user can easily and safely pour water without worrying about the water injection operation.

The amount of water injected into the hot water storage tank 10 is set to 2.2 to 3.02, and the amount of water injected is determined by the water pipe (
(not shown) is displayed on the water amount display section 101 that is visible from the outside of the machine body 1, so that the required amount of water to be injected can be confirmed. can be easily done without having to remove it each time.

After pouring water into the hot water storage tank 1o, the lid 3o is removed and assembled into the body 1 in the reverse order.

At this time, the hot water storage tank 10 is communicated with the outside only through the gap between the upper surface opening 32 and the valve body 37 of the bellows pump 34 via the inlet 28 .

Then, when the operation button 94 is operated to close the power switch 93, the tank water boiling heater 11 and the tank warming heater 12 are energized to heat the water in the hot water storage tank 10. At this time, the water boiling indicator lamp 98 to which 100 cm is applied turns on as the 1 indicator lamp, and the heat retaining indicator lamp 99 does not turn on because the lamp resistance a causes current to flow to the thermostat 19 side.

Then, due to the heat generated by the tank water boiling heater 11 and the tank heat retaining heater 12, the water temperature rises by 1-9 degrees.
If the thermostat 19 is set to operate and open at ~92°C, the thermostat 19 will automatically open when the water temperature reaches .

Then, the boiling water indicator lamp 98 and the tank water heater 11 become a parallel circuit (between A and B), and a voltage is applied to the heat retention indicator lamp 99 through the common contact B. Naturally, the lamp resistance is high (lamp resistance is 33Ω, and the tank water heater is about 100Ω) The heat retention indicator lamp is 1 to 99Ω.
A voltage close to oov is applied, and only a small voltage is applied between contacts A and B. Therefore, the kettle indicator lamp 98 does not light up, and the tank kettle heater 11 does not generate heat. The reverse pressure heat retention indicator lamp 99 lights up, and the hot water storage tank 1o is heated and kept warm only by the tank heat retention heater 12.

TR320, which controls the tank heater 12, has a differential (ON and O
Normally, the tank water heater 11 will not generate heat again, and after opening one thermostat in the hot water storage tank 1Q, the water temperature will rise further and the TR320
The heat retention state is turned on and off at around 96-98℃ by control.
L, maintain.

The body 1 is normally energized and stores hot water in this heat-retaining state.

Then, when you want to drink coffee or when you want to brew coffee immediately for unexpected customer service, coffee extraction can be completed in a short time without requiring a water pouring operation.

To do this, grasp the handle 103 of the case 61, slide the rail 58, and take out the case lid 6 from the extraction storage section 8.
4 is removed, a paper filter 60 filled with the required number of cups of coffee powder is set, the case lid 64 is broken off, and the case 61 is again inserted into the upper part of the extraction storage section 8.

The cup 75 is covered with a cup lid 77 and placed on the cup mounting portion 76.
Attach to. At this time, the circular bulge 78 of the cup lid 77
pushes up the cup lid abutting protrusion 74 of the operating lever 68 from below, and the lower extraction port 66 of the filter case 61 is opened.

Then, a necessary amount of hot water corresponding to the amount of coffee powder is stored in the hot water storage case 49. (At this time, the flow rate control valve 51 is closed.) This can be done by repeatedly pushing down the push plate 36 on the top of the lid body 30 by hand, and the lower surface of the push plate 35 pushes the valve body 37. , the upper surface opening 32 of the bellows pump 34 is closed with the seal ring 36, and the hot water storage tank 1 is closed.
0 has a sealed structure, and when the push plate 35 is further pushed down, the internal pressure of the tank 1o increases, and with this pressure, hot water can be spouted from the opening 47 of the discharge port 46 through the hot water pipe 26, and from the socket 48. Hot water is supplied into the hot water storage case 49.

The amount of hot water supplied is determined by the water level gauge 5 provided in the hot water storage case 49.
6 allows for visual confirmation, and the user only has to stop operating the push plate 35 after dispensing the required amount.

Thereafter, the valve knob 55 is operated to set the pouring time of 3 to 4 minutes at a position suitable for the number of brewing cups, and the valve 51 is opened.

The hot water is dispersed into the diffuser 62 of the case lid 64 through the communication hole 57, and then poured into the coffee powder in the filter case 61 from the sprinkling hole 63.

The coffee liquid is filtered by a paper filter 60, and the dripping hole 73 is energized from the lower Th outlet 65 opened, and then the coffee liquid is passed through the case lid 7.
It remains in the cup 75 through the opening hole 79 of No. 7.

By operating the operation button 96, the coffee liquid stored in the Kangua 5 is heated to a high temperature by closing the cup warming switch 95 and energizing the cup warming heater 84 to heat the cup 5 downward. It maintains the extracted coffee at an appropriate temperature for a long time, preventing the ingredients from deteriorating and preserving the taste. In addition, when the operation button 96 is operated, the cup heat retention indicator lamp 100 connected in parallel with the cup heat retention heater 84 lights up, indicating that the power is on.

The operation button 96 of this cup heat retention heater 84 can be operated as needed, and if it is not needed, the cup heat retention switch 9
6 should be opened.

When pouring coffee, if only the cup 75 is taken out from the brewing storage section 8, the resistance of the operating lever 68 to the spring 66 is released, and the spring 66 closes the brewing port p5 with the brewing valve 67, allowing the coffee liquid to flow downward. This prevents the dripping of the coffee liquid from dripping onto the body, and the coffee liquid can be used hygienically without staining the heat insulating plate 82, the outer surface of the machine body 1, or even the floor surface with the dripped coffee liquid.

After use, the coffee grounds in the filtration case 61 are thrown away together with the paper filter 60, and the inside of the filtration case 61 is simply washed with water and the cup 75 is cleaned.

The use of the hot water is not limited to brewing coffee, for example, it may be used to brew black tea or green tea, or even just to dispense hot water. In the case of only hot water supply, the valve function 51, 67) can be opened and the water can be stored in the lower cup 75, or the filter case 61 and cup 75 can be removed and the lower part of the hot water storage case 49 can be opened. Hot water may be supplied directly to the equipment used from the sprue 5o.

This hot water can be used repeatedly, and the amount of hot water in the hot water storage tank 1o can be checked on the water amount display section 101, and if water needs to be poured, it can be poured in the same manner as the above-mentioned water pouring operation. Then, the temperature inside the hot water storage tank 10 drops rapidly and reaches below the return temperature of the thermostat 19, so the thermostat 19 is energized, the heat retention indicator lamp 99 goes out, and 1 ooV is applied to the boiling water indicator lamp 98 and the tank water heater 11. , the water boiling indicator lamp 98 lights up,
The tank water boiling heater 11 generates heat and repeats the above-described water boiling and warming operation of the hot water storage tank 10.

Regarding cleaning inside the water storage tank 1o, remove the lid 30 from the aircraft body 1 and lift up the inner lid 21 to open the wide opening part of the water storage tank 10, and since there is no water supply pipe 26 etc., the water can be stored. Cleaning inside the tank 1o becomes easier.

Further, since the discharge port 45 and the hot water supply pipe 26 can be removed together from the inner lid 21, they can be easily cleaned, and parts can be easily replaced in the event of a breakdown.

As described above, according to this embodiment, the hot water storage tank 1o capable of keeping high-temperature hot water is provided in the body 1, and has the function of maintaining the hot water in a usable state as needed, and the hot water storage tank 1o having a flow rate control valve function. Since it is configured to include a case 49,
The hot water is kept at a temperature of 96 to 98 degrees Celsius, and the temperature at which it comes into contact with the coffee is as high as 94 to 96 degrees Celsius. This fully satisfies the basic extraction condition of ``complete extraction within minutes''.

To effectively extract the active ingredients contained in coffee powder, suppress the contamination of defective ingredients, fully bring out the flavor of coffee, and obtain a flavorful and delicious coffee liquid.

In addition, this extraction condition is based on the valve knob 65 of the water storage case 49.
If you adjust it according to the number of cups, the opening area of the pouring hole will change. If there are many cups, the opening area will increase, and if there are few cups, the opening area will decrease and the pouring will take 3 to 4 minutes. With this device, you can extract all the cups of coffee you want to brew under ideal extraction conditions that bring out the full flavor of the coffee. This is possible with a simple operation of knob 55).

In addition, this 3 to 4 minute extraction completion time is the minimum time required to extract delicious coffee liquid, and the time required for preparation, which is the time required to supply hot water to the hot water storage case 49, also ensures that the user can feel at ease and have a stable operation time. As a result, the time required for pouring water and wasted time for heating cold water as in the conventional method is eliminated, resulting in the shortest preparation time. Therefore, when you want to drink coffee, brew coffee, or extract coffee for unexpected customer service, you can easily and deliciously prepare it.

In addition, the amount of extraction can be made from one cup, and there is no restriction on the amount of extraction, and it can be widely adopted, and can be used not only for general household use but also for commercial use with a large number of cups.

In addition, since the hot water storage case 49 is configured to be removably attached to the body 1, only the hot water storage case 49 can be removed from the body 1 and washed with water.
The inside of the hot water storage case storage section 9 can be cleaned more easily, and can be used hygienically.

In addition, the water temperature in the hot water storage tank 10 is controlled by the tank heat retention heater 1.
2 and TBS20 can efficiently keep the coffee at a high temperature for a long period of time, so it is configured so that delicious coffee liquid can always be extracted and drunk at a high temperature as needed.

In addition, the operation of supplying hot water from the hot water storage tank 1o into the hot water storage case 49 is possible by pushing down the bellows pump 34 with the push plate 35, and the operation is easily and reliably performed by the user with a simple suppressing action. Since it does not require a complicated configuration using a motor or the like, it can be manufactured with a simple configuration.

The coffee liquid that has been extracted and remains in the cup 75 is removed by controlling the energization of the cup warming heater 84.
It is possible to keep delicious coffee liquid at an appropriate temperature for a long time, and it is possible to preserve the delicious taste of coffee until you want to drink it.

In addition, this operation can be operated by the user at will, and if you drink it immediately after brewing and do not need the heat retention function, you can turn on the power switch 93.
It is easy to use and economical because it can be operated separately to turn off the power.

In addition, the cup 75 can also be taken out independently of the filtration case 61, and the extraction port 65 at the bottom of the filtration case 61 is provided with a valve function that is linked to the operation of putting in and taking out the cup 75. Easy to pour coffee,
In addition, dripping of coffee liquid from the filter case 61 can be reliably prevented with a simple configuration, and the coffee liquid does not stain the heat insulating plate 82, the floor surface, etc., and is sanitary.

Also, hot water storage case 49. a case 61 and cup 7
Since the operation for putting in and taking out the cup can be limited to one direction (possible in three directions for the cup), it can be installed in a corner next to a wall, etc., without unnecessary operations, making it convenient to use. It also makes the installation space wider and more convenient.

The operation of pouring water into the shattered hot water storage tank 10 can be easily performed by removing the lid 30 and leaving the inner lid 21 attached to the upper part of the hot water storage tank 10. The injection guide plate 22 and the four earthen walls 15 that stand up around the outer periphery of the inner lid 21 prevent the injected water from scattering outside the machine and allow it to flow smoothly into the hot water storage tank 10. Therefore, water can be poured reliably.

Furthermore, the inside of the hot water storage tank 10 can be easily cleaned by removing the inner lid 21, making it simple and sanitary.

Coffee can always be extracted using boiling water with few impurities, so you can always drink delicious coffee.

In addition, the hot water storage tank 10 and the hot water storage case 49 are provided with a visually visible water level display section 101 and a water level gauge 56, so that the user can check and operate the water level gauge 56, and the operation can be performed reliably and easily. obtain.

In addition, since hot water can be boiled and kept warm for a long time, it can be installed in locations farther away than tap water, increasing its installation location and range of use, making it highly valuable.

Further, FIG. 6 shows an improved version of the above embodiment for hot water supply, in which a discharge port 45 is provided projecting above the eaves 5, one end is fitted into a water pipe bushing 46, and the other end opening 47 is fixed. The water pipe bushing 46 is centered around the water pipe 26.
