Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and particularly to an uninterrupted continuous extraction coffee machine. Background Art

[0002] Coffee is a widely popular beverage, which is made by roasting and grinding coffee beans and then extracting them with hot water. It contains ingredients such as caffeine, has a unique aroma and taste, can refresh the mind, and is deeply loved by people all over the world. A coffee machine is an electrical appliance mainly used for making coffee. It uses infrared radiation to heat coffee beans or coffee powder, and then extracts them into fragrant coffee through high-pressure steam. The coffee machine not only simplifies the coffee-making process but also ensures that coffee with a consistent taste can be obtained each time;

[0003] Existing automatic coffee machines generally consist of five parts: 1. a bean grinder, 2. a coffee powder chuck, 3. a water tank, 4. a hot water nozzle, and 5. a steam foamer. The single-unit working mechanism makes it a single-unit automatic coffee machine;

[0004] Existing automatic coffee machines have an independent working mechanism, work individually, and do not combine with other machines. The products are monotonous and unified. Adding auxiliary ingredients such as ice cubes requires manual modulation. It is a single-unit automatic coffee machine and is not convenient for continuous coffee extraction. Therefore, new technical solutions need to be designed to solve this problem. Summary of the Invention

[0005] The purpose of the present invention is to provide an uninterrupted continuous extraction coffee machine to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An uninterrupted continuous extraction coffee machine, including a main frame, the main frame is fixedly installed on the top of a base, and a coffee bean bin is connected to the top of the main frame;

[0007] A bean grinder is fixedly connected to the bottom of one side of the main frame, the bean grinder is connected to the coffee bean bin, a brewer is arranged below the bean grinder, the brewer is fixedly installed on the top of the base, a water heating boiler is fixedly connected to one side wall of the main frame, a gear pump is communicated with the bottom of the water heating boiler, the output end of the gear pump is connected to the brewer, a coffee storage liquid pipe is arranged on one side of the brewer, the brewer and a coffee storage tank are communicated through a conduit, and a float valve is installed in the coffee storage tank.

[0008] It should be noted that the float valve, the bean grinder, the brewer, and the gear pump are all connected to an external controller, so that the control program can be set in advance for control.

[0009] By adopting the above technical solution, hot water is heated by a water heating boiler. After the hot water is heated to a specified temperature, a coffee grinder is used to grind coffee beans. When a certain amount of coffee beans are ground, the ground coffee beans enter the brewer. Then, a gear pump is used to extract the hot water in the water heating boiler into the brewer to brew coffee to form coffee liquid. Then, the coffee liquid will enter the coffee storage tank for storage. And when a certain amount of coffee liquid is stored, a float valve will send a signal to the controller, and the controller will stop the coffee grinder, brewer, and gear pump. The user can take coffee through the control valve at the end of the coffee storage tank. When the coffee liquid in the coffee storage tank decreases, the float valve will automatically send a signal to the controller, so as to start the coffee grinder, brewer, and gear pump again to work, thereby realizing continuous extraction of coffee liquid and improving the use effect.

[0010] As a preferred embodiment of the present invention, a water tank is fixedly installed on one side wall of the water heating boiler. A water pump is fixedly installed on the lower side of the water tank. One end of the water pump is communicated with a flow meter, the outer end of the flow meter is connected to the water heating boiler, and the other end of the water pump is connected to the water tank.

[0011] By adopting the above technical solution, the water pump can pump the water in the water tank into the water heating boiler, thereby realizing water replenishment for the water heating boiler. And the flow meter can measure the replenished water, thereby realizing accurate water replenishment. The flow meter and the water pump are electrically connected to the controller, so that after a certain amount of water is replenished, the controller will automatically stop the water pump.

[0012] As a preferred embodiment of the present invention, an electric heater and a temperature sensor are installed in the inner cavity of the water heating boiler.

[0013] By adopting the above technical solution, the temperature sensor and the electric heater are both electrically connected to the controller. Thus, the water heating boiler uses the electric heater to heat the water. And during the heating process, the temperature sensor can be used to detect the temperature. Thus, after reaching the specified temperature, the controller will send an instruction to the electric heater to stop heating.

[0014] As a preferred embodiment of the present invention, the water heating boiler further includes a liquid level gauge, and the liquid level gauge is installed through the top of the water heating boiler.

[0015] By adopting the above technical solution, the liquid level gauge is used to detect the water level in the inner cavity of the water heating boiler. And the liquid level gauge is electrically connected to the controller. Thus, when the liquid level is insufficient, a signal is sent to the controller, and the controller will start the water pump for automatic water replenishment.

[0016] As a preferred embodiment of the present invention, a high-precision weighing device is connected to the end of the coffee bean bin, and the high-precision weighing device is fixedly connected to the top of the main frame.

[0017] By adopting the above technical solution, when importing coffee beans into the coffee grinder for grinding, the high-precision weighing device can be used to weigh the remaining coffee beans in the coffee bean bin, so as to accurately control the amount of coffee beans ground.

[0018] As a preferred embodiment of the present invention, a coffee waste bin is communicated with the waste liquid outlet of the brewer.

[0019] By adopting the above technical solution, the setting of the coffee waste bin enables the collection of coffee waste liquid, which is beneficial to avoiding environmental pollution caused by the overflow of coffee waste liquid.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the present invention, the gear pump is used to fill the water heating boiler with water until the water in the water heating boiler is full. The water heating boiler heats the water and makes the water temperature reach the set temperature. After the water temperature reaches the set temperature, the coffee grinder starts to work, that is, starts to grind coffee beans. When the coffee powder is ground to the set weight, the coffee grinder stops grinding. The brewer starts to squeeze the coffee powder and stops squeezing after reaching the set pressure. Immediately afterwards, the gear pump starts to add water. The hot water in the water heating boiler flows into the brewer to extract coffee liquid. The extracted coffee liquid flows into the coffee storage tank. After the extraction is completed, the coffee residue is automatically discharged into the waste bin. By using the float valve ball arranged in the coffee storage tank, the coffee liquid can be automatically extracted again to supplement when the coffee liquid is insufficient, so as to realize continuous and uninterrupted extraction, bringing convenience to users.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "set" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The models of the electrical appliances provided in the present invention are only for reference, and different models of electrical appliances with the same function can be replaced according to the actual use situation.

[0029] Please refer to Figure 1 , the present invention provides a technical solution: an uninterrupted continuous extraction coffee machine, including a main frame 1, the main frame 1 is fixedly installed on the top of the base, and a coffee bean bin 11 is connected to the top of the main frame 1;

[0030] At the bottom of one side of the main frame 1, a grinder 3 is fixedly connected. The grinder 3 is connected to the coffee bean bin 11. A brewer 2 is arranged below the grinder 3. The brewer 2 is fixedly installed on the top of the base 1. A water heating boiler 6 is fixedly connected to one side wall of the main frame 1. A gear pump 5 is communicated with the bottom of the water heating boiler 6. The output end of the gear pump 5 is connected to the brewer 2. A coffee storage pipe 10 is arranged on one side of the brewer 2. The brewer 2 and the coffee storage tank 10 are communicated through a conduit. A float valve is installed in the coffee storage tank 10.

[0031] It should be noted that among them, the float valve, the grinder 3, the brewer 2, and the gear pump 5 are all connected to an external controller, so that the control program can be set in advance for control.

[0032] It should be understood that hot water is heated by the water heating boiler 6. After the hot water is heated to the specified temperature, the coffee grinder 3 is used to grind coffee beans. When a certain amount of coffee beans is ground, the ground coffee beans enter the brewer 2. Then, the gear pump 5 is used to extract the hot water in the water heating boiler 6 into the brewer 2 to brew coffee to form coffee liquid. Then, the coffee liquid will enter the coffee storage tank 10 for storage. And after storing a certain amount, the float valve will send a signal to the controller, and the controller will stop the coffee grinder 3, the brewer 2 and the gear pump 5 from working. The user can take coffee through the control valve at the end of the coffee storage tank 10. When the coffee liquid in the coffee storage tank 10 decreases, the float valve will automatically send a signal to the controller, so as to start the coffee grinder 3, the brewer 2 and the gear pump 5 to work again, thus realizing continuous extraction of coffee liquid and improving the use effect.

[0033] Further, a coffee waste bin 7 is connected to the waste liquid outlet of the brewer 2. The setting of the coffee waste bin 7 enables the collection of coffee waste liquid, which is conducive to avoiding environmental pollution caused by the overflow of coffee waste liquid.

[0034] As Figure 1 shown; a water tank 9 is fixedly installed on one side wall of the water heating boiler 6. A water pump 8 is fixedly installed on the lower side of the water tank 9. One end of the water pump 8 is connected to a flow meter 4. The outer end of the flow meter 4 is connected to the water heating boiler 6, and the other end of the water pump 8 is connected to the water tank 9;

[0035] It should be understood that the water pump 8 can pump the water in the water tank 9 into the water heating boiler 6 to realize water replenishment for the water heating boiler 6. And the flow meter 4 can measure the replenished water, so as to realize accurate water replenishment. The flow meter 4 and the water pump 8 are electrically connected to the controller, so that after replenishing a certain amount of water, the controller will automatically stop the water pump 8 from working.

[0036] As Figure 1 shown; an electric heater and a temperature sensor are installed in the inner cavity of the water heating boiler 6;

[0037] It should be understood that the temperature sensor and the electric heater are both electrically connected to the controller. Thus, the water heating boiler 6 uses the electric heater to heat the water. And during the heating process, the temperature sensor can be used to detect the temperature. So after reaching the specified temperature, the controller will send an instruction to the electric heater to stop heating.

[0038] As Figure 1 shown; the water heating boiler 6 further includes a liquid level gauge, and the liquid level gauge is installed through the top of the water heating boiler 6;

[0039] It should be understood that the liquid level gauge is used to detect the water level in the inner cavity of the water heating boiler 6. And the liquid level gauge is electrically connected to the controller. Thus, when the liquid level is insufficient, a signal is sent to the controller, and the controller will start the water pump 8 to automatically replenish water.

[0040] As shown Figure 1 in the figure, a high-precision weighing device is connected to the tail end of the coffee bean bin 11, and the high-precision weighing device is fixedly connected to the top of the main frame 1. Thus, when the coffee beans are imported into the coffee grinder 3 for grinding, the remaining coffee beans in the coffee bean bin 11 can be weighed by the high-precision weighing device, so as to accurately control the amount of ground coffee beans.

[0041] The working principle is as follows: First, start the work through the controller, and perform grinding treatment through the coffee grinder 3. During the grinding process, the high-precision weighing sensor will weigh the remaining coffee beans, so as to control the amount entering the coffee grinder 3. The ground coffee powder enters the brewer 2, and then the electric heater in the water heating boiler 6 heats the water, and the temperature sensor can detect the temperature. When the temperature reaches the required value, the gear pump 5 will extract hot water and import it into the brewer 2 for brewing coffee liquid, and the extracted coffee liquid will be imported into the coffee storage tank 10 for storage. When the liquid volume in the coffee storage tank 10 reaches a certain level, the float valve will lift, and thus the controller will receive a signal and automatically stop the coffee grinder 3, the brewer 2, and the gear pump 5. The user can take coffee through the control valve at the tail end of the coffee storage tank 10. When the coffee liquid in the coffee storage tank 10 decreases, the float valve will automatically feedback a signal to the controller, and then the coffee grinder 3, the brewer 2, and the gear pump 5 will be restarted to work, so as to continuously extract coffee liquid and improve the use effect.
