Description

Non-electric extracting apparatus which driving at setting temperature}

The present invention relates to a non-electric extraction device operated at a set temperature.

In general, beverages such as tea (TEA) or coffee can be purchased and consumed manufactured, or purchased as tea bags or instant products and manufactured and consumed directly.

In recent years, as tea and coffee have become more popular, an increasing number of people are purchasing raw materials such as coffee bean powder or tea leaf powder to make tea or coffee, and making and drinking beverages according to their personal preferences.

Coffee can be produced by various methods, such as the hand drip method, the espresso machine method, a type of coffee machine, the French press method, and the Mocha pot method.

The hand drip method is one of the widely used coffee manufacturing methods. A cone-shaped filter paper is placed on a funnel-shaped dripper, coffee bean powder is placed in it, and then hot water is poured into the coffee bean powder and flows down into a container located below the dripper. It is a manufacturing method.

The espresso machine method, in which temperature and pressure are controlled by electricity, is a method of quickly extracting coffee from ground coffee beans using an espresso machine, and the French press method is a syringe-like method that puts ground coffee powder into a tube-shaped glass container and makes hot coffee. This refers to a method of extracting coffee by pouring water and pressurizing the coffee bean powder through a metal filter.

The conventional moka pot method is a device that extracts coffee liquid using the pressure of steam generated from heated water. It has the advantage of being able to easily and conveniently make high-quality coffee liquid depending on the type even if you are not an expert, so it has recently been used at home. This is one of the most widely used methods.

The moka pot method has the advantage that anyone can easily use it, but it also has the disadvantage that the temperature and pressure of the heated water are limited and the controllable range is narrow, so the coffee extracted is somewhat inferior in taste and aroma compared to the espresso method. In addition, since it takes time to fill the basket with ground coffee beans and wash them again, there was the inconvenience of making it difficult to reuse a cup of coffee immediately after brewing it.

Meanwhile, a capsule coffee machine is a device that stores ground coffee beans in a capsule, seals it, and then extracts coffee by passing hot water through a hole formed by drilling a hole in the sealing film when used.

Coffee beans preserved in capsules have the advantage of high freshness as they can be stored for a relatively long time, but there is no configuration that can control temperature and pressure variables like a conventional moka pot, so there is a disadvantage in producing the best coffee taste. .

The technical problem that the present invention aims to solve is that even in an environment where electricity is not provided, as long as a heat source is provided, it can be operated at a preset pressure and temperature, coffee can be extracted using a conventional capsule coffee, and it can be immediately reused without the hassle of washing. The goal is to provide a non-electric extraction device that operates at a possible set temperature.

Another technical problem that the present invention aims to solve is that even in an environment where electricity is not provided, water at the desired temperature can be easily obtained as long as a heat source is provided, so that, for example, a set temperature can be obtained to obtain tea beverages at the optimal temperature, etc. It provides a non-electrical extraction device that runs on .

In order to solve the above-described technical problem, a non-electric extraction device operated at a set temperature according to the present invention includes a water filling part that is filled with water and receives heat, leaving a predetermined gas space; A basket portion including a supply pipe and a heat-operated valve; An upper container part containing the coffee liquid that has passed through the basket part, wherein the supply pipe has a capsule containing ground coffee beans seated thereon, defines a flow path from the water filling part to the upper container part, and the heat-operated valve. is coupled to the inside of the supply pipe to open and close the flow path defined in the supply pipe by the operation of the piston. The piston has a sharp upper end, and is raised when the temperature set at the time of manufacture is higher than the temperature set at the time of the heat operation valve. Thus, the passage can be opened while penetrating the capsule.

In one embodiment of the present invention, the piston includes an opening and closing plate that opens and closes a first opening formed inside the supply pipe; and a through hole through which water rising along the opened first opening flows in from one part and is discharged from another part.

In one embodiment of the present invention, an elastic body that provides restoring force to the piston may be further included.

In one embodiment of the present invention, it further includes a cover part that covers the upper part of the supply pipe and includes a perforation part disposed adjacent to the upper part of the capsule accommodated in the upper part of the supply pipe, wherein the piston penetrates the capsule to a predetermined depth. It further includes a push plate for lifting the capsule, and when the capsule is raised by the push plate, at least a portion of its upper surface may be perforated by the perforation part.

In order to solve the above-described technical problem, a non-electric extraction device operated at a set temperature according to the present invention includes a water filling part that is filled with water and receives heat, leaving a predetermined gas space; A basket portion including a supply pipe and a heat-operated valve; An upper container part containing water that has passed through the basket part; wherein the supply pipe defines a flow path from the water filling part to the upper container part, and the thermally actuated valve defines a flow path defined in the supply pipe by the operation of a piston. It is coupled inside the supply pipe to open and close, and the piston rises when the temperature of the thermally operated valve exceeds the temperature set at the time of manufacture, and the passage can be opened by the upward movement.

In one embodiment of the present invention, it further includes a receiving member that accommodates a tea bag containing tea leaves or tea powder and is coupled to the upper container portion, wherein the receiving member is formed by combining the upper and lower hemispheres in a hinged manner. A through hole can be formed through which water passes only in the upper hemisphere.

The present invention operates at a preset pressure and temperature as long as a heat source is provided even in an environment where electricity is not provided. Coffee can be extracted using a conventional capsule coffee and can be immediately reused without the hassle of washing.

The present invention provides a non-electric extraction device operated at a set temperature that can easily obtain water at the desired temperature even in an environment where electricity is not provided as long as a heat source is provided, for example, tea beverages at the optimal temperature, etc. It is provided.

Since the present invention can be modified in various ways and can have various embodiments, specific embodiments will be illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all transformations, equivalents, and substitutes included in the spirit and technical scope of the present invention.

In describing the present invention, if it is determined that a detailed description of related known technologies may obscure the gist of the present invention, the detailed description will be omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, the non-electric extraction device 1 (hereinafter simply referred to as 'extraction device 1') operated at the set temperature according to the present invention will be described in detail with reference to the attached drawings.

The heat providing unit 100 can be used as anything that can transfer heat to the water filling unit 200, such as a portable gas burner, induction, etc. However, it is preferable to use a heat providing unit 100 that can control the heat transfer temperature manually or electrically, rather than using one that continuously transfers excessively high heat.

As described above, the heat providing unit 100 can use an electric heating means, but it is different from the extraction device according to the present invention in that it does not use electricity. When using a non-electrical product as the heat providing unit 100, such as a gas burner, the present invention has the advantage of being able to be implemented even in an environment without electricity.

Referring to Figure 1, the extraction device 1 according to the first embodiment of the present invention may include a water filling part 200, a first basket part 300, and an upper container part 400.

The water filling unit 200 includes a filling container 210 and a safety valve 220.

The filling container 210 may be formed to have a certain volume so that water (W) can be filled therein. The longitudinal area of the filling container 210 may become wider as it goes downward.

The size of the filling container 210 may be determined to include a space where atmospheric pressure can be formed in addition to the amount of water for extracting coffee.

When water (W) is heated, the gas inside the filling container 210 receives the heat and the pressure increases. In this case, the water (W) inside the filling container 210 may flow out to the outside due to the pressure difference between the gas inside the filling container 210 and the external gas. The water (W) inside the filling container 210 passes sequentially through the supply pipe 310, capsule 330, and discharge pipe 420 and is provided with the force to come out through the discharge port 425. However, while the thermal operation valve 320 is closed, this flow may be partially restricted.

The top of the filling container 210 may be open. Water (W) can be filled from the top of the open filling container 210, and the filter basket unit 300 can be inserted from the open top of the filling container 210 and coupled to the filling container 210.

A handle (H) may be connected to the outer surface of the filling container 210.

The filling container 210 may be made of stainless steel or aluminum to receive heat, but is not necessarily limited thereto. For example, the filling container 210 may be made of tempered glass material that is durable against heat. However, even in this case, it is preferable that the bottom surface that transmits heat is made of a metal material. If the filling container 210 is transparent, the flow state of water (W) can be observed.

The safety valve 220 may be coupled through one side of the filling container 210.

The safety valve 220 may be coupled to communicate with the inside of the filling container 210 in a closed state.

The safety valve 220 may be opened when pressure exceeds a certain level. Therefore, the safety valve 220 can prevent the filling container 210 from being damaged due to excessive internal pressure.

Depending on the embodiment, the safety valve 220 may be installed in a structure that selectively opens and closes by the user's external force.

FIG. 2 is a cross-sectional view showing the first basket portion 300 equipped with the capsule of FIG. 1.

Referring to FIG. 2 , the first basket unit 300 may include a supply pipe 310 and a thermally actuated valve 320.

The supply pipe 310 may be formed as a whole into a pipe (PIPE) shape. The interior of the supply pipe 310 may be divided into an upper part, a middle part, and a lower part, and the middle part and the lower part may be communicated by the first opening hole 311, and the upper part and the middle part may be communicated by the second opening hole 313. there is.

The first opening hole 311 can be opened and closed by the thermally operated valve 320.

The second opening hole 313 may provide a passage through which the piston 321 passes.

A support plate 315 may be formed on the lower part of the supply pipe 310.

The support plate 315 supports the thermally actuated valve 320 from the bottom.

The support plate 315 may have holes formed through it to allow water to pass except for the parts necessary to support the thermally actuated valve 320.

The lower part of the thermally actuated valve 320 is supported by the support plate 315.

When the heat-operated valve 320 reaches a set temperature, the piston 321 rises to communicate with the lower part of the supply pipe 310 and the central flow path.

The thermally actuated valve 320 may be installed at a position such that the upper portion of the piston 321 can penetrate one surface of the capsule 330 when the piston 321 moves upward.

The elastic body 327 may be installed in a form that provides restoring force to the opening and closing plate 323.

For example, one end of the elastic body 327 may be installed to contact the lower surface of the upper partition surface (i.e., supported by the structure of the supply pipe 310), and the other end may be installed to contact the upper surface of the opening and closing plate 323.

The elastic body 327 may have the shape of, for example, a coil spring.

The thermally actuated valve 320 may contain a thermal expansion material such as paraffin therein. The thermal expansion material is coupled to the lower part of the piston 321 inside the thermally actuated valve 320, and is expanded by heat to raise the piston 321.

The temperature at which the piston 321 operates may vary depending on at least one of the type and amount of the thermal expansion material included in the thermally actuated valve 320. For example, when the temperature reaches 80°C or higher, the piston 321 receives rapid expansion pressure and moves (strokes) upward a predetermined distance. For example, when the temperature reaches 93°C or higher, the piston 321 receives rapid expansion pressure and moves (strokes) upward a predetermined distance. For example, when the temperature reaches 95°C or higher, the piston 321 receives rapid expansion pressure and moves (strokes) upward a predetermined distance. At this time, the piston 321 protrudes further outward by a predetermined distance. The thermally actuated valve 320 can be manufactured in response to the desired temperature (set temperature).

The thermally actuated valve 320 may be operated based on various temperatures as in the above-described example, and the set temperature at which the thermally actuated valve 320 operates may be determined when the thermally actuated valve 320 is manufactured. In fact, for products that are driven by heat, the customer can set the desired operating temperature within the possible range of -5℃ to 100℃, for example.

In addition, as described above, the thermally actuated valve 320 is a component that is driven by thermal factors and can operate at a set temperature without using electricity.

The opening and closing plate 323 may be coupled around the outer axis of the piston 321.

The lower surface of the opening and closing plate 323 faces or is spaced apart from the structure of the supply pipe 310 at the first opening hole 311, so that the flow path can be opened and closed at the first opening hole 311.

The opening/closing plate 323 blocks the flow path of the supply pipe 310 below the set temperature (see FIG. 5), but when the temperature exceeds the set temperature, it rises along with the rise of the piston 321 and closes the flow path at the position of the first opening hole 311. can be opened (see Figure 6).

The piston 321 may have a plurality of through holes 325 formed on its outer surface. A portion of the through hole 325 may define a passage through which elevated water flows, and another portion of the through hole 325 may define a passage through which the introduced water is discharged. The through hole 325 located in the middle of the supply pipe 310 allows water to flow in, and the through hole 325 located in the upper part of the supply pipe 310 allows water to discharge.

The upper part of the piston 321 may be inserted through one surface of the capsule 330. Therefore, the water discharged from the upper part of the piston 321 through the through hole 325 can wet the ground coffee beans (P/C) and extract the coffee liquid (E) (see FIG. 6).

That is, the piston 321 rises to a position where the lower part of the capsule 330 penetrates, and at the same time, the flow path at the position of the first opening hole 311 can be opened. When the flow path is opened, water rising along the supply pipe may flow into the capsule 330 through the through hole 325.

Meanwhile, in the first embodiment of the present invention, the piston 321 is illustrated as having a sharp upper portion, but is not necessarily limited to this embodiment. For example, the piston 321 may include a plurality of needles (not shown) aligned upward. These needles can form holes on the bottom of the capsule 330, like commercially available capsule machines. In this case, of course, the diameter of the second opening hole may be longer than that in the first embodiment.

The water flowing into the capsule 330 may be converted into coffee liquid (E) and flow into the discharge pipe 420.

The coffee liquid (E) flowing through the discharge pipe 420 may be discharged through the discharge port 425 and collected in the upper container 410.

A basket-shaped space may be provided at the top of the supply pipe 310.

A capsule 330 containing ground coffee beans (P/C) may be inserted into the upper part of the supply pipe 310 by the user.

As seen in the drawing, water flows in from the bottom of the capsule 330 and becomes coffee liquid (E) and is discharged to the top.

The flow path below the capsule 330 may be formed by the piston 321.

The flow path at the top of the capsule 330 can be formed in various ways. For example, the flow path in the upper part of the capsule 330 may be manufactured in a pre-formed state. That is, the upper part of the capsule 330 may have a plurality of through holes formed in advance.

The passage at the top of the capsule 330 may be formed using the upward force of the piston 321. For this purpose, a perforation portion 345 may be placed on the capsule 330.

The upper part of the supply pipe 310 may be manufactured to be openable and closed by the cover part 340.

Referring to FIG. 3, the cover portion 340 may include an upper plate 341, a flow path 343, and a perforation portion 345.

The upper plate 341 may be formed in the shape of a disk.

The upper plate 341 may be formed with a flow path 343 through which the coffee liquid (E) can flow. For example, a flow path 343 having a smaller diameter than the upper plate 341 may be formed in the center of the upper plate 341.

The flow path 343 may be formed such that the lower diameter corresponds to the outer diameter of the perforated portion 345. Accordingly, the perforated portion 345 can be fitted into the upper plate 341 through the flow path 343. The perforation part 345 may not necessarily be a necessary component when using a product in which a flow path is already formed in the upper part of the capsule 330.

The upper part of the upper plate 341 may include a pipe (PIPE) shape that protrudes upward from the flow path 343. The outer diameter of the upper part of the upper plate 341 may correspond to the inner diameter of the discharge pipe 420. Therefore, the upper part of the upper plate 341 can be fitted into the discharge pipe 420.

The perforation part 345 may include a plurality of needles 347.

A plurality of needles 347 may be arranged radially from the center (P) of the lower surface of the perforation portion 346.

Each of the needles 347 is formed in the shape of a small diameter pipe (PIPE), and the lower part may be formed in a sharp shape like an injection needle.

The needle 347 may be inserted through the upper part of the capsule 330 and may form a passage leading to the discharge pipe 420.

The needle 347 does not necessarily have to be formed in a tubular shape, and may be formed in a shape with a closed inner diameter. This is because if the upper part of the capsule 330 is penetrated by the needle 347, a gap large enough for water to flow may be created.

Meanwhile, in order for the above-described plurality of needles 347 to be inserted through the capsule 330, a process is required in which the capsule 330 is lifted upward in accordance with the rise of the piston 321. For this, the piston ( 321) A push plate 329 may be further formed on the outer surface.

The push plate 329 is formed approximately in the shape of a disk and can pass through the second opening hole 313.

When the push plate 329 rises, it comes into contact with the lower surface of the capsule 330 and lifts the capsule to a predetermined height (H1). At this time, the needle 347 may be inserted from the top of the capsule 330 to a predetermined depth (H2). Although H2=H1 is shown in the first embodiment of the present invention, it is not necessarily limited thereto.

The upper container portion 400 may provide a space to accommodate the coffee liquid (E) extracted through the first basket portion (330).

The upper container portion 400 may include an upper container 410 and a discharge pipe 420.

The upper container 410 may be made of stainless steel or aluminum, but is not necessarily limited thereto. For example, the upper container 410 may be made of tempered glass material that is durable against heat. When the upper container 410 is transparent, the flow state of water (W) can be observed.

The upper container 410 can be manufactured to fit the shape so that it can be detached from the upper part of the supply pipe 310 and maintain airtightness.

A handle (H) may be provided on the outer surface of the upper container 410.

The discharge pipe 420 may be formed in the shape of a pipe (PIPE) having a vertical length.

The lower portion of the discharge pipe 420 may be formed to communicate with the flow path defined by the supply pipe 310. The discharge pipe 420 may have an discharge port 425 formed at the top. The outlet 425 may define an outlet through which the coffee liquid (E) can be discharged into the upper container.

A cap 421 may be formed at the top of the discharge pipe 420 to guide the coffee liquid (E) to the lower part of the upper container 410.

Hereinafter, the method of using and operation of the extraction device 1 according to the first embodiment of the present invention will be described in detail with reference to the attached drawings. Prior to explanation, it is assumed that the water filling part 200, the first basket part 300, and the upper container part 400 are coupled to each other in such a way that airtightness is maintained, and the water filling part 200 contains water (W ) will be described starting from the state in which the capsule 330 is inserted into the chamber 310.

As shown in FIG. 4, when the water filling unit 200 containing water (W) is placed on the heat providing unit 100 and heated, the temperature of the air inside the water filling unit 200 increases. According to the law of thermodynamics (PV = nRT), the pressure increase is proportional to the temperature increase, so the pressure of the air inside the water filling unit 200 increases and pushes the water (W) toward the supply pipe 310.

The water (W) rises along the inside of the supply pipe 320 and rises around the thermal operation valve 320 to transfer heat to the thermal operation valve 320.

Meanwhile, the air pressure inside the water filling unit 200 gradually increases and rises until the thermally operated valve 320 operates and a flow path is formed. At this time, the maximum atmospheric pressure can be determined by determining the volume excluding the water (W) to be filled in the water filling unit 200. In other words, the higher the desired maximum atmospheric pressure, the smaller the remaining volume of the water filling unit 200 (volume of space excluding water) can be determined to design the water filling unit 200. This design takes into account the law of thermodynamics (PV=nRT), where volume is inversely proportional to pressure.

If possible, the maximum pressure can be designed as close to 9 bar. According to another embodiment, the maximum pressure may be set higher than 9 bar. This is in consideration of the fact that as the filled water (W) increases, the gas volume inside the water filling unit 200 increases and the pressure gradually decreases, and this is intended to bring the average pressure during the extraction process close to 9 bar.

When the heat operation valve 320 reaches the set temperature, the passage at the first opening hole 311 is simultaneously opened by the upward movement of the piston 321. Accordingly, the heated water W may continue to rise along the supply pipe 310.

The set temperature of the thermally actuated valve 320 is preferably 93°C. Meanwhile, the set temperature at which the thermal operation valve 320 is opened may be set lower than 93°C. Because it may take time for the water (W) and the thermally actuated valve 320 to reach thermal equilibrium, the thermally actuated valve 320 can be designed to open at a lower temperature when the water (W) reaches 93°C. Because there is.

Water (W) flows into the capsule 330 through a plurality of holes 325 formed in the piston 321. The introduced water (W) is mixed with ground coffee beans (P/C) to form coffee liquid (E).

The coffee liquid (E) continues to rise along the flow path defined by the discharge pipe 410 and may be discharged to the discharge port 425.

When extraction of coffee is completed, the user can stop heating by the heat providing unit 100.

The flow path within the supply pipe 310, which was opened by the upward movement of the piston 321, is closed as the thermally operated valve 320 cools. In this process, the elastic body 327 assists the internal structure of the supply pipe 310 and the opening/closing plate 323 to press each other through restoring force so that the flow path can be closed again.

By using the above method, the user can pour out the coffee liquid (E) from the upper container 410 and enjoy it.

According to an embodiment of the present invention, the coffee liquid (E) can taste the same as or very close to espresso.

The present invention adopts the advantages of the moka pot as is and includes a heat-operated valve 320 to determine the extraction temperature and the volume inside the water filling unit 200 to determine the maximum pressure, so that the extraction conditions are the same as those of commercial espresso. It has the effect of providing conditions very similar to these.

The present invention simultaneously achieves the opening of the supply pipe 310 and the formation of a flow path into the capsule 330 (including the operation of the piston 321 rising and stabbing) by using the piston 321 of the heat-operated valve 320. There are important technical effects that can be achieved.

In addition, the present invention can extract coffee at a set temperature and pressure even in environments where electricity is not available, such as remote areas, and uses existing types of coffee capsules to remove coffee powder remaining in the basket after use, cleaning, etc. It has the effect of allowing you to brew the next coffee right away without it.

Figure 8 is a diagram showing a non-electric extraction mechanism 2 (hereinafter simply referred to as 'extraction mechanism 2') operated at a set temperature according to a second embodiment of the present invention. If the concept of the present invention is more generalized, it can be said to be an extraction device that obtains water at a desired temperature, and the second embodiment of the present invention embodies this technical idea.

Referring to Figure 8, the extraction device 2 according to the second embodiment of the present invention may include a water filling part 200, a second basket part 500, and an upper container part 400.

Since the water filling unit 200 is the same as in the first embodiment of the present invention, its detailed description will be omitted.

The second basket unit 500 may include a supply pipe 510 and a thermally actuated valve 520.

The supply pipe 510 is divided into an upper and lower part, and a heat-operated valve 520 may be placed in the lower part.

The thermally actuated valve 520 is supported by a support plate 515, and the structure, coupling relationship and shape of the support plate 515 with the thermally actuated valve 520 are the same as those of the support plate 315 of the first embodiment of the present invention.

The thermally actuated valve 520 may be coupled to a piston 521 so that it protrudes upward from the inside. The piston 521 is coupled to the thermally actuated valve 520 so that it protrudes when the set temperature is reached by the thermal expansion material inside the thermally actuated valve 520.

The piston 521 may be coupled with an opening and closing plate 523 at the top.

The opening/closing plate 523 may open or close the passage in conjunction with the upward or downward movement of the piston 521 in the same manner as the opening/closing plate 323 in the first embodiment. At this time, the elastic body 527 assists the downward movement of the piston 521 when the thermally operated valve 520 cools, thereby assisting in closing the passage.

Since the upper container portion 400 is the same as described in the first embodiment, repeated description will be omitted, and the receiving member 600, which is an additional component compared to the first embodiment, will be described.

The receiving member 600 may be able to open and close by hingedly combining two hemispheres.

The receiving member 600 may be made of a metal material.

The receiving member 600 can have a tea bag (T/B) inserted therein with leaves or tea powder (P/T) for tea extraction.

While no through holes are formed in the lower hemisphere of the receiving member 600, a plurality of through holes 620 may be formed in at least a portion of the upper hemisphere.

The receiving member 600 may be connected to the upper part of the upper container 410 by a connecting means 610 such as a chain having a predetermined length.

The technical purpose of the extraction device 2 of the second embodiment of the present invention is to accurately obtain water at a desired temperature without special manipulation. This is to ensure that water of the appropriate temperature for extraction of each beverage can be easily obtained since the optimal extraction temperature may vary depending on the type of beverage desired. Meanwhile, the thermally actuated valve 520 can be designed to be replaceable depending on the combination type. If the heat-operated valve 520 is installed to be replaceable, water of different temperatures can be obtained depending on the set temperature of the heat-operated valve 520.

Water at the desired temperature can be immediately poured into a separate container and used for tasks such as brewing tea, but tea can also be brewed directly in the upper container 410 using the receiving member 600.

For example, when the receiving member 600 is placed inside the upper container 410 filled with water at a desired temperature, the water penetrates into the receiving member 600 and the tea bag (T/B) inside the inserted tea bag (T/B) As the dissolution of T) progresses, the T solution (T) can be extracted.

When the T solution (T) is formed as desired, the user can remove the receiving member 600 from the upper container 410 and place it on the outer surface of the upper container 410. At this time, the T solution (T) can be prevented from flowing from the receiving member 600 by lightly wiping off the moisture on the lower part of the receiving member 600. This is because the through hole 620 is not formed in the lower hemisphere of the receiving member 600.
