Description

[0001] This invention claims priority to the provisional application with application number 63423019 and, if applicable, the provisional application with application number 63345905. Background Art

[0002] A kettle of boiling water has played an important role in civilization. Since the very beginning, humans have been constantly improving methods of controlling liquids. From a cup of tea to nuclear energy, a kettle of boiling water has transformed our daily lives.

[0003] When the inventor first saw the vacuum coffee device invented by Loeff in Berlin in the 1830s, it inspired the idea of a better solution for liquid / gas / pressure control.

[0004] In terms of the prior art, Mr. RHO YOUNG GYU from South Korea (Publication No.: KR20180036221) and Mr. WILLIAMS from the United States (Publication No.: 2022 / 147360) are the closest to this invention. Their claims propose that liquid can be controlled by opening a nozzle.

[0005] The difference between this invention and the inventions proposed by the aforementioned RHO and WILLIAMS is that when under pressure, the gas / vapor generated in the lower chamber can be controlled by the liquid flow through the same channel / opening.

[0006] In addition, the device proposed by this invention can control the amount of pressure in the pressurized chamber, which is not reflected in the prior art, especially the prior art of RHO and WILLIAMS.

[0007] There are other significant inventions related to this invention in terms of coffee brewing methods and fluid dynamics, but none of them have the ability to draw / extract liquid and / or gas through the same opening / channel.

[0008] This small adjustment is beneficial because users can pre-treat their brewing materials with steam before the hot water completely submerges the materials, thereby better extracting the brewed product and generating a pleasant aroma. In addition, contrary to liquid-dominated applications, users can use this invention as a steamer. Moreover, this invention can adjust the amount of liquid and / or gas transported through the channel, thus enabling precise control of all fluids in the device. Additionally, this invention can adjust the magnitude of the pressure generated by the device before using the pressure for its intended purpose. For example, it is difficult to make espresso without pressure. Another example is a household water heater, which can generate hot water for bathing / showering and / or switch to steam for a steam room.

[0009] In addition, the present invention proposes that the user can modify the device to utilize the extracted liquid and / or gas. In addition, the device proposed by the present invention can be compact and portable, and its components can be placed in the boiling chamber, thus facilitating personal carrying and being very suitable for camping and other extracurricular activities.

[0010] The benefits of this system are not limited to brewing. The inventor believes that it improves the way scientists conduct experiments. The inventor is not a nuclear engineer, but the inventor thinks this may help form a safety layer and / or improve the overall performance of nuclear power plants. In addition, small barrels and pressurized liquid and / or gas containers, such as gas cylinders, can also benefit from the method of the present invention. In addition, the present invention can be beneficial to carburetors because carburetors rely on the mixture of air and liquid.

[0011] Another significant difference between the present invention and the previous claims is the ability of the present invention to produce brewed products and generate electricity through a hydraulic and / or turbine generator. Therefore, a portable hydraulic and / or turbine generator can also extract brewed products. Summary of the Invention

[0012] The present invention is a method for controlling the flow of fluid in and out of a chamber. More specifically, it controls the flow of liquid and / or gas in and out of at least one opening of a pressurized container. In addition, this is a way of using a valve to change the pressure direction to move the liquid and / or gas out of or into the container through at least one opening. In addition, the container can be heated to boil the liquid inside the container, thereby pressurizing the pressurized chamber so that the liquid and / or gas is discharged from the pressurized chamber. The heated liquid can be moved and used to extract substances such as coffee. The liquid and / or gas extracted in and out of the pressurized container can be used for power generation.

[0013] The present invention is a device that can control fluids in various substance states or densities through the same opening as long as the fluid is under pressure. In addition, the pressure can be generated by the change from liquid to gas (from water to steam) through a heat source or by the change from gas to liquid through condensation. The lower chamber is a container with at least one opening at the top, where a fluid control component can be placed. The fluid control component has at least one opening and a corresponding valve capable of opening and closing the opening. The opening on the fluid control component is a channel for the liquid extending into the lower chamber. The channel has a valve that opens the outlet on the channel, and the valve is in contact with the steam or above the water level line in the lower chamber. In addition, the fluid control component has at least two openings, which have their respective opening valves and respective channels, and the channels have outlets that can be adjusted on their respective channels. All the openings / outlets in the said invention can be adjusted to the open, closed, partially open, and partially closed states, so that precise control can be exerted on all the fluids in the process. Brief Description of the Drawings

[0014] Figure 1 Shows a lower chamber (1) with a handle (2), the lower chamber (1) being filled with a portion of liquid water (100), and 101 represents the water level line (101).

[0015] Figure 2 Shows a lower chamber (1) filled with a portion of water (100) and a fluid control assembly (10) firmly mounted on the opening of the lower chamber (1). The fluid control assembly (10) has two channels (11, 12), and these two channels have respective main valves (11m, 12m), outlets (11n, 12n) and respective valves (11v, 12v). The portion of the channel (12) located within the filter housings (30, 31b) is fitted with a wire mesh filter (31b) and a porous ceramic filter (31a), and the filter housings (30, 31b) are adapted to the opening (41) at the bottom of the upper chamber (40).

[0016] Figure 3 Shows the assembled device (1000) with all valves (11m, 11v, 12m, 12v) in the open position. A heat source (400) in the form of a fire (400) from a furnace heats the water (100) in the lower chamber (1) to generate steam (200), and the steam (200) is discharged from the two channels (11, 12) via the open outlets (11n, 12n), where the steam (200) is discharged from the nozzle on the channel (11) and is introduced into the upper chamber (40) through the filters (31a, 31b) in the channel (12), and in the upper chamber (40), the steam (200) meets the coffee grounds (300).

[0017] Figure 4 Shows that by adjusting the two exhaust valves (11v, 12v) to a partially open state, the device (1000) can extract liquid (100) and steam (200) from the two channels (11, 12). The positive pressure (201) in the form of steam (200) accumulates faster than its rate of escaping through the outlets (11n, 11m), thereby pushing the liquid (100) through the channels (11, 12) to be mixed with the steam (200) through the partially open outlets (11n, 12n). The mixture of steam (200) and water (100) is discharged from the channel (11) and is introduced into the upper chamber (40) in the channel (12), where the mixture meets the coffee grounds (300) in the upper chamber (40) and is brewed together to produce liquid coffee (500).

[0018] Figure 5It shows that only the liquid 100 flows into the upper chamber (40). By closing the ball valve (11m) and the exhaust valve (12v) on the channel (12), the liquid (100) flows upward along the channel (12) into the upper chamber (40), where it is brewed together with the coffee grounds (300) to produce liquid coffee (500).

[0019] Figure 6 It shows that if the exhaust valve (12v) is opened wide enough, when the coffee is being brewed ( Figure 5 ), the brew (500) can be allowed to flow back down into the lower chamber (1). Steam (200) / pressure (201) escapes from the outlet (12n) and bubbles upward through the brew in the upper chamber (40).

[0020] Figure 7 It shows another way that when brewing is in progress and the liquid is boiling in the lower chamber (1), the liquid is brought down from the upper chamber (40) to the lower chamber (1). By opening the main valve (11m) on the channel (11), the outlet (11n) is in the open state, the coffee is brewed in the upper chamber (40), and due to the reduced pressure in the lower chamber (1), the coffee grounds mixture passes downward through the filters (31a, 31b) into the lower chamber (1). Since the main valve (12m) on the channel (12) is in the open state. The brewed filtered coffee (500) returns to the lower chamber (1).

[0021] Figure 8 It shows another way that the liquid is brought down from the upper chamber (40) to the lower chamber (1) while another channel (11) is closed. When the user determines that the mixing of the hot liquid (100) and the coffee powder (300) is complete, the heat source (400) is removed. After a period of time, the water vapor / steam (200) in the lower chamber (1) begins to condense into liquid and creates a negative pressure (202) inside the lower chamber (1), thereby sucking the brew from the upper chamber (40) through the filters (31a, 31b) into the lower chamber (1) as the brewed filtered coffee.

[0022] Figure 9 is Figure 8 a continuation of, showing that if there is sufficient negative pressure, the atmosphere (205) is sucked into the lower chamber (1) until the pressure in the lower chamber (1) is very close to atmospheric pressure.

[0023] Figure 10It shows that the brewed filtered coffee (500) in the lower chamber (1) is heated (400), the channel (12) is closed by the valve (12m), the channel (11) is in the open state, and the outlet (11n) on the channel (11) is closed, so that the brewed filtered coffee (500) flows out through the channel (11), and thus can be served in a cup for drinking.

[0024] Figure 11 It shows that the liquid (100) for brewing liquid coffee (500) circulates by entering the channel (11) from the lower chamber (1). The channel (11) has an elongated spout that guides the liquid to the top of the upper chamber (40). The liquid meets the coffee grounds in the upper chamber (40) and finally enters the lower chamber (1) downward. Among them, the above situation occurs due to the partial opening restriction of the valve (12m).

[0025] Figure 12 It shows that the heat source (400) can magnify or focus (452) the sunlight (451). The sun (450) projects the light (451) into the magnifying glass (453), thereby focusing the light (452) on the lower chamber (1). In addition, the reflective material (454) is arc-shaped, focusing the sunlight (451) onto the bottom of the lower chamber (1), so that the liquid (100) in the lower chamber (1) is heated and steam (200) is generated. Part of the steam (200) is restricted by the exhaust valves (11v, 12v), and the liquid (100) and steam (200) are discharged from the two channels (11, 12). A generator (80) is installed in the channel (11), and the mixture of steam and liquid (200, 100) rotates the turbine (81), thereby rotating the rotor (82) in the stator (83), and the current is connected to the light bulb (85) through a set of wires (84) to light up the light bulb (85). Therefore, the present invention can be a portable hydraulic and / or turbine generator capable of generating renewable energy.

[0026] Figure 13 It shows the channels (11, 12) and their related components. The related components are disassembled and placed in the lower chamber (1). The upper chamber (40) is placed upside down in the lower chamber (1), and the disassembled fluid control assembly (10) is used as a lid to hold all the above components in the lower chamber (1). This is to illustrate that the device (1000) and the present invention can accommodate all the components of the device in the lower chamber (1) to form a compact and portable device that can even be held in the hand. It should be noted that if it is not for portability, the present invention can be of any size. Figure 13 It represents a smaller device (1000) of a compact and portable coffee machine and a hydraulic and / or turbine generator. Detailed Description

[0027] The present invention is a method for guiding liquid and / or gas to enter and exit a container from at least one opening when the fluid is under pressure. The pressure can come from a liquid substance in a heated and pressurized chamber. The liquid that turns into steam accumulates to exert pressure on the liquid in the pressurized chamber. The valve attached to the bottom / pressurized chamber opening can be adjusted to:

[0028] The device has a lower chamber having at least two openings extending into the lower chamber, and these openings can be open, closed, or partially open or closed. A portion of the liquid is boiled, and the outlet with the corresponding valve can be opened, closed, or partially open or closed so as to interact with the water vapor / steam in the lower chamber. The first channel extends out of the lower chamber in the form of a nozzle, and the second channel extends into the upper chamber through a set of filters.

[0029] In the device of this embodiment, a set of channels / openings and valves connected to the lower chamber as a lid refer to the fluid control assembly.

[0030] The boiling chamber / lower chamber can be provided with a safety outlet that releases the pressure in the container if the pressure reaches the release threshold of the safety outlet. Since the safety outlet does not interfere with the function of the device and its method of use, it will not be mentioned further below.

[0031] Throughout the description of the present invention, when describing water, it should be understood that liquids, etc. should be interchangeable with water or fluids with a higher density. In addition, when describing steam, it should be understood that gases, water vapor, etc. should be interchangeable with steam or fluids with a lower density.

[0032] The valves in this specification are separate and independent of each other, but it should be understood that these valves can be combined or can affect each other. For the purpose of illustrating the method of the present invention, these valves are shown in a rough manner.

[0033] The pressure of the device in this specification will focus on the pressure generated by heating / cooling the fluid in the pressurized chamber. However, it should be noted that the pressure mentioned in this specification can be generated in any way. Therefore, heating is a means of generating a pressure difference between the pressurized chamber and the atmospheric pressure or outside the pressurized chamber. For example, the pressure difference can include, but is not limited to, a chemical reaction of the liquid in the pressurized chamber, a pump applied to one opening of the pressurized chamber, or air moving at high speed outside the device.

[0034] Throughout the specification, the description of the lower chamber that boils the liquid can also be replaced with the bottom chamber, the pressurized chamber, the boiling chamber, or the pot.

[0035] The heat source or heating element in the specification refers to an open flame, such as a stove top burner. However, the heat source can be any type of heat source; a heat source such as concentrated solar energy, magnified solar energy, geothermal ventilation, or an electric kettle.

[0036] The processes and functions in the description can also be programmed into the electric kettle to select and time the openings and valves in the device, so as to direct the flow of liquid and / or gaseous fluids according to the user's needs.

[0037] In this specification, when extracting materials for brewing, brewing coffee is mainly used as an example. However, it should be noted that the material can be any material that can be extracted or benefited from according to the method of the present invention.

[0038] In this application, the connections between the components of the device should be secure threaded connections. The connections between the components of the device can be any secure connection considered appropriate by the world / user. The drawings are only rough schematic diagrams according to the principle, rather than technical drawings of the product.

[0039] Unless otherwise specified, the materials of the present invention should be considered stainless steel. However, it should be noted that any material that can hold liquids and control valves without affecting the seal can be used. Preferably, the lower chamber and the upper chamber are made of glass, but this may be dangerous.

[0040] The present invention can be better understood by referring to the drawings of this application and reading the following content.

[0041] Pour a certain amount of liquid (100) into the lower chamber (1)( Figure 1 ). The lower chamber (1) is a container that can hold liquid and has an open top. Then, a fluid control assembly (10) with two openings (11, 12) / channels (11, 12) is installed on the opening of the lower chamber (1), and the openings (11, 12) / channels (11, 12) have respective valves (11m, 12m) for opening, closing, partially opening, and partially closing the openings / channels (11, 12), and the respective outlets (11n, 12n) on each channel (11, 12) are controlled by valves (11v, 12v) for opening, closing, partially opening, and partially closing the outlets (11n, 12n)( Figure 2 ) The channels (11, 12) extend into the lower chamber (1) and are in contact with the liquid (100) inside the lower chamber (1)( Figure 2-3 ) The first channel (11) is equipped with a nozzle, and the second channel (12) is equipped with a filter (31a, 31b) inside a filter housing (30, 31b), and the filter housing (30, 31b) is assembled in the bottom opening (41) of the upper chamber (40)( Figure 2-3 ) A heat source (400) is used to boil a certain amount of liquid (100) in the lower chamber (1) to generate steam (200), and the steam (200) escapes through the two openings (11, 12) via the respective open outlets (11n, 12n)( Figure 3) The steam (200) discharged from the device (1000) via the first channel (11) can steam the milk in different containers (cups) (not shown), while the steam (200) discharged through the second channel (12) enters the upper chamber (40) from the lower chamber (1) through a set of filters (31a, 31b), meets the coffee grounds (300) already placed in the upper chamber (40) in the upper chamber (40), and steams the coffee grounds (300)( Figure 3 )。Both exhaust valves (11v, 12v) are adjusted to be partially open to limit some of the pressure (201) generated by the steam (200) accumulating in the lower chamber (1), so that some liquid (100) and some steam (200) are discharged through the first and second channels (11, 12)( Figure 3 )。The mixture of liquid and steam (100, 200) leaves the first channel (11) through the nozzle. At the same time, the mixture of liquid and steam (100, 200) meets the coffee grounds (300) in the upper chamber (40) through the second channel (12), causing the hot liquid (100) to accumulate in the upper chamber (40) and start brewing with the coffee grounds (300) in the upper chamber (40)( Figure 4 )。By closing the first channel (11) through the valve (11m) and closing the opening (12n) through the exhaust valve (12v) on the second channel (12), only the liquid (100) enters the upper chamber (40) through the second channel (12), meets the coffee grounds (300) in the upper chamber (40) and brews together inside the upper chamber (40), producing liquid coffee (500)( Figure 5 )。The liquid coffee (500) mixture (300, 100) in the upper chamber (40) can be sent back down to the lower chamber (1) through the filters (31b, 31a). The heat source (400) is still used to heat the lower chamber (1). By opening any one or a combination of the valve (12v) and / or opening the valve (11v), opening the valve (11m), the pressure (201) inside the lower chamber (1) can be released so that the liquid coffee (500) flows back down to the lower chamber (1) by gravity( Figure 6-7 )。An alternative way to make the liquid coffee (500) enter the lower chamber (1) is to remove the heat source (400). After removing the heat source (400) for a period of time, a negative pressure (202) is generated inside the lower chamber (1) through the condensation of the steam (200) into the liquid (100), so as to suck the liquid coffee (500) into the lower chamber (1) through the filter. The filter allows the liquid (100) and the gas (200) to pass through, but does not allow the solid (300) to pass through( Figure 8)。If there is sufficient negative pressure (202) in the lower chamber (1), after all the liquid coffee (500) has been sucked out of the upper chamber (40), the lower chamber (1) inhales the atmosphere (205) until the pressure in the lower chamber (1) is equal to the atmospheric pressure or the pressure outside the lower chamber (1). Figure 9 )。After the brewed filtered liquid coffee (500) is collected in the lower chamber (1), the user can tilt the device (1000) towards the outlet nozzle of the first channel (11) (not shown) to pour out the liquid coffee (500) from the device (1000). The second channel (12) remains open, or the second opening / channel (12) is closed by a valve (12m), the first channel (11) is opened by a valve (11m), and the outlet (11n) is closed. The heat source (400) is used to generate pressure (201) through steam (200) such that pressure (201) is generated on the water level line (101) in the lower chamber (1), causing the brewed filtered liquid coffee (500) to flow out of the first channel (11) and thus into a selected cup or container. Figure 10 )。The device (1000) can be configured such that the first channel (11) leads to an opening at the top of the upper chamber (40), allowing fluid to pass through from the lower chamber (1) and leave the first channel (11) to enter the upper chamber (40), and then return downward through filters (31a, 31b) to the lower chamber (1) for circulation. The above circulation can be achieved because the valve (12m) on the second channel (12) is partially opened while the valve (11m) on the first channel (11) is fully opened, and the fluid tends to flow along the path of least resistance. Figure 11 )。So far, the heating element (400) has been an open flame, but it can be any heat source, such as concentrating (452) or magnifying (452) sunlight (451), where the sunlight (451) from the sun (450) is guided and focused through a magnifying glass (453) and / or a reflective material (454) to heat the lower chamber (1). The lower chamber (1) pressurizes the fluid (100, 200) such that the fluid can be guided through the first opening / channel (11), and the nozzle of the first opening / channel (11) is connected to a generator to rotate the turbine (81), which in turn rotates the rotor (82) in the stator (83), thereby powering the light bulb (85) through the wire (84). Figure 12 )。When the user has finished using the device (1000), the components of the device, including the upper chamber (40), can be assembled into the lower chamber (1), and the remaining part of the fluid control assembly acts as a lid to confine the components in the lower chamber (1), thus obtaining a portable coffee device capable of generating electricity using hydropower and / or a turbine.
