Intelligent pour-over coffee machine with fully automatic micro-circulation temperature control system

Abstract

This utility model relates to a fully automatic micro-circulation temperature control system for an intelligent pour-over coffee machine, including a main heating chamber and an auxiliary heating chamber. The auxiliary heating chamber and the main heating chamber are connected by a pipeline. The auxiliary heating chamber is used to preheat the water in the auxiliary heating chamber, and the main heating chamber is used to perform secondary heating. The main heating chamber forms a water circulation loop. Through the water circulation loop of the main heating chamber, the water in the main heating chamber can circulate and be heated, making the water temperature more uniform and almost without deviation. At the same time, because the water is heated while circulating in the first circulation loop, the second circulation loop and the main heating chamber, this circulation process will cause the cold water stored inside the water circulation loop components to participate in the internal circulation, so that the components of the entire water circulation loop are preheated until the temperature is uniform and consistent with the set temperature.

Description

Technical Field

[0001] This utility model belongs to the field of coffee machine technology, specifically relating to a fully automatic micro-circulation temperature control system for an intelligent pour-over coffee machine. Background Technology

[0002] Currently, the simulated pour-over coffee machines on the market are mainly divided into commercial, home, and portable models. Due to structural limitations and functional requirements, the heating methods used in these machines are primarily instant heaters or storage heaters. These have some drawbacks: Instant heaters initially produce water at a low temperature, typically requiring 3-5 seconds to reach the required brewing temperature. Storage heaters have a large volume, resulting in significant and inconsistent water temperatures at different points, leading to large temperature fluctuations and inaccurate temperature control. The longer heating time required to brew a cup of coffee can waste the user's time and patience. Furthermore, when either type of heater is far from the brewing spout, the spout temperature drops considerably. These shortcomings greatly affect the water temperature, resulting in poor coffee quality and taste.

[0003] Therefore, it is necessary to further improve and perfect the technology to provide an intelligent simulated pour-over coffee machine that features short coffee processing time, easy and precise control of the outlet temperature, high level of intelligence, and a fully automatic micro-circulation temperature control system to ensure the taste and flavor of the brewed coffee. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a fully automatic micro-circulation temperature control system for an intelligent pour-over coffee machine, which adopts a dual heating mode to heat water and reduce heating time.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a fully automatic micro-circulation temperature control system for an intelligent hand-drip coffee machine, including a main heating box and a secondary heating box. The secondary heating box is connected to the main heating box through a pipeline. The secondary heating box is used to preheat the water in the secondary heating box, and the main heating box is used to perform secondary heating on the main heating box. The main heating chamber forms a water circulation loop, which includes a first circulation pipe, a second circulation pipe, a first pump body, and a solenoid valve. One end of the first circulation pipe is connected to the first water inlet of the main heating chamber, and the other end of the first circulation pipe is connected to the solenoid valve. One end of the second circulation pipe is connected to the solenoid valve, and the other end is connected to the output end of the first pump body. The water inlet of the first pump body is connected to the first water outlet of the main heating chamber. The solenoid valve is located at the water outlet of the coffee machine body. The solenoid valve is used to control the connection between the second circulation pipe and the water inlet of the coffee machine body or the connection between the second circulation pipe and the first circulation pipe.

[0006] Furthermore, the main heating box includes a first box body, which has a first water outlet, a first water inlet, a first water outlet and a first water vapor outlet. The first box body is equipped with a first temperature sensor, a first heater and a first water level controller.

[0007] Furthermore, the auxiliary heating box includes a second box body, which has a second water outlet, a second water inlet, a first drain outlet, and a second water vapor outlet. An automatic temperature controller, a second heater, and a second water level controller are installed inside the second box body.

[0008] Furthermore, the fully automatic micro-circulation temperature control system of the intelligent pour-over coffee machine is applied to the coffee machine body; The coffee machine body includes a base, a column, a water outlet arm, and a water tank. The base includes a placement area and a connection area. The column is located on the upper surface of the connection area. The water outlet arm is located above the column. The main heating box is located inside the column. The auxiliary heating box is located inside the water tank. The solenoid valve is located at the water outlet end of the water outlet arm. The water circulation loop is located inside the water outlet arm. The placement area is located below the water outlet end of the water outlet arm.

[0009] Furthermore, there are two water outlet arms, which are arranged above the column and spaced apart. There are two placement areas, each corresponding to the water outlet end of one of the two water outlet arms. The main heating box and the auxiliary heating box are in two sets, and each set of the main heating box and the auxiliary heating box is used to heat and supply water to the two water outlet arms respectively.

[0010] Furthermore, a rotating platform is provided on the placement area.

[0011] Furthermore, a lifting assembly is provided below the rotating platform, which is used to drive the rotating platform to move up and down.

[0012] Furthermore, the water tank is equipped with a tap water inlet, a bottled water inlet, and a tank outlet. The number of tank outlets corresponds to the number of auxiliary heating tanks. Either the tap water inlet or the bottled water inlet is connected to the second water inlet of the auxiliary heating tank; the tank outlet is connected to the second water outlet of the auxiliary heating tank.

[0013] Furthermore, a second pump body is provided at the inlet end of the second water inlet of the auxiliary heating box, and a third pump body is provided at the outlet end of the second water outlet. The second pump body draws water into the auxiliary heating box, and the third pump body is used to discharge the water in the auxiliary heating box to the main heating box.

[0014] Furthermore, the water tank is also equipped with a drain valve, a tap water valve, and a tank control box. The drain valve is used to control the first drain outlet on the auxiliary heating tank to drain water. The tap water valve is used to control the connection between the tap water inlet and the second water inlet. The tank control box is used to control the operation of the valves and pumps in the water tank.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Improved coffee brewing efficiency. The main and auxiliary heating chambers operate independently, with separate water temperature controls. The auxiliary heating chamber can operate simultaneously with the main heating chamber, preheating the water in its tank to a preset temperature. This ensures a higher incoming water temperature for the main heating chamber, reducing the need for further temperature increases and thus improving its efficiency, shortening brewing time. This allows those waiting for their coffee to enjoy their premium coffee more quickly.

[0016] 2. Precise control of brewing water temperature. The main heating chamber's water circulation loop ensures uniform and consistent water temperature, virtually eliminating deviations. Simultaneously, as the water circulates within the first, second, and main heating chambers while being heated, this circulation process draws in cold water stored within the circulation loop components, preheating all components until they reach the set temperature. During coffee brewing, this preheating minimizes temperature loss, maintaining consistency with the set temperature. This eliminates temperature variations, guaranteeing consistent taste for every brew of the same coffee. Attached Figure Description

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0020] like Figures 1-8 As shown, this embodiment provides a fully automatic micro-circulation temperature control system for an intelligent pour-over coffee machine, including a main heating chamber 5 and a secondary heating chamber 6.

[0021] The main heating chamber 5 is located inside the coffee machine body, and the auxiliary heating chamber 6 is located inside the water tank 4. The auxiliary heating chamber 6 and the main heating chamber 5 are connected by a pipeline. The auxiliary heating chamber 6 is used to preheat the water in the auxiliary heating chamber 6. Specifically, the auxiliary heating chamber 6 includes a second chamber, which has a second water outlet 61, a second water inlet 62, a first drain outlet 63, and a second water vapor outlet 64. The positions of the second water outlet 61, the second water inlet 62, the first drain outlet 63, and the second water vapor outlet 64 are set according to actual needs. The second chamber is equipped with an automatic temperature controller 65, a second heater 66, and a second water level controller 67.

[0022] The main heating box 5 is used for secondary heating. Specifically, the main heating box 5 includes a first box body, which has a first water outlet 51, a first water inlet 52, a first water outlet 53 and a first water vapor outlet 54. The positions of the first water outlet 51, the first water inlet 52, the first water outlet 53 and the first water vapor outlet 54 are set according to actual needs. The first box body is equipped with a first temperature sensor 55, a first heater 56 and a first water level controller 57.

[0023] The main heating chamber 5 forms a water circulation loop 7, which includes a first circulation pipe 71, a second circulation pipe 72, a first pump body 73, and a solenoid valve 74. One end of the first circulation pipe 71 is connected to the first water inlet 52 of the main heating chamber 5, and the other end of the first circulation pipe 71 is connected to the solenoid valve 74. One end of the second circulation pipe 72 is connected to the solenoid valve 74, and the other end is connected to the output end of the first pump body 73. In this embodiment, the solenoid valve 74 is a two-position three-way solenoid valve 74. The water inlet end of the first pump body 73 is connected to the first water outlet 51 of the main heating chamber 5. The solenoid valve 74 is set at the water outlet position of the coffee machine body. The solenoid valve 74 is used to control the second circulation pipe 72 to connect with the water inlet of the coffee machine body or to connect the second circulation pipe 72 with the first circulation pipe 71.

[0024] The operating control principle of the coffee making process is as follows: When the coffee machine receives the coffee making process instruction and completes the preheating process, the main heating chamber 5 continues to heat while simultaneously running a micro-circulation heating within the water circulation loop 7 of the main heating chamber 5. This ensures that the water in the main heating chamber 5 circulates and heats, making the water temperature more uniform and almost without deviation. At the same time, because the water is heated while circulating within the water circulation loop 7, it also drives the cold water stored inside the components of the water circulation loop 7 to participate in the internal circulation, causing all components within the water circulation loop 7 to be preheated until the temperature is uniform and consistent with the set temperature. When the set temperature for the coffee making process is reached, the first heater 56 is turned off to stop heating; the two-position three-way solenoid valve 74 connected to the first water inlet 52 of the main heating chamber 5 is closed, and the water outlet connected to the coffee machine body is opened to discharge hot water.

[0025] This solution also provides a coffee machine body, including a fully automatic micro-circulation temperature control system, a base 1, a column 2, two water outlet arms 3 and a water tank 4.

[0026] The base 1 includes a placement area 12 and a connecting area 11. There are two placement areas 12. The uprights 2 are located on the upper surface of the connecting area 11. Two water outlet arms 3 are located above the uprights 2 and spaced apart. The two placement areas 12 correspond to the water outlet ends of the two water outlet arms 3 respectively. There are two main heating boxes 5, which are spaced apart vertically inside the uprights 2. Two auxiliary heating boxes 6 are located inside the water tank 4. Each set of main heating boxes 5 and auxiliary heating boxes 6 is used to heat and supply water to the two water outlet arms 3 respectively.

[0027] The back of the base 1 has a left main water inlet 13, a right main water inlet 14, a power interface 15, a communication interface 16, and a main exhaust interface 17. The left main water inlet 13 and the right main water inlet 14 are respectively connected to the first water inlet 53 of the two main heating boxes 5 for adding water to the main heating boxes 5. The main exhaust interface 17 is connected to the first water and air outlet 54 of the two main heating boxes 5 for venting.

[0028] A rotating platform 121 is provided on the placement area 12. The rotating platform 121 adopts the rotating structure commonly used in the existing coffee machine placement area 12, which will not be described in detail here. A lifting component 122 is provided below the rotating platform 121. The lifting component 122 is used to drive the rotating platform 121 to move up and down. The lifting component 122 is implemented by a structure of a fixed block, a slider and a fork-type lifting arm. The slider moves closer to the fixed block, and the two support legs of the fork-type lifting arm connected to the fixed block and the slider move closer to each other to achieve the upward movement.

[0029] The water tank 4 is equipped with a tap water inlet 41, a bottled water inlet 42, and a tank outlet 43. The number of tank outlets 43 corresponds to the number of auxiliary heating tanks 6. In this scheme, there are two auxiliary heating tanks 6. Either the tap water inlet 41 or the bottled water inlet 42 is connected to the second water inlet 62 of the auxiliary heating tank 6. The tank outlet 43 is connected to the second water outlet 61 of the auxiliary heating tank 6. Specifically, the inlet end of the second water inlet 62 of the auxiliary heating tank 6 is equipped with a second pump body 47, and the outlet end of the second water outlet 61 is equipped with a third pump body 48. The second pump body 47 draws water into the auxiliary heating tank 6, and the third pump body 48 is used to discharge the water in the auxiliary heating tank 6 to the main heating tank 5.

[0030] The water tank 4 is also equipped with a drain valve 44, a tap water valve 45 and a tank control box 46. The drain valve 44 is used to control the first drain port 63 on the auxiliary heating box 4 to drain water. The tap water valve 45 is used to control the connection between the tap water inlet 41 and the second water inlet 62. The tank control box 46 is used to control the operation of the valve body, pump body and other components in the water tank 4.

[0031] Main component piping distribution and operation control method: The auxiliary heating box 6 is installed in the water tank 4. The water source (bottled water or tap water) is connected to the corresponding interface (tap water inlet 41 or bottled water inlet 42) of the water tank 4. The tap water inlet 41 or bottled water inlet 42 is connected to the corresponding second pump body 47 and third pump body 48 for bottled water (tap water is connected to the corresponding tap water valve 45). The second water inlet 62 of the auxiliary heating box 6 is connected to the second pump body 47. The second water outlet 61 of the auxiliary heating box 6 is connected to the third pump body 48. The third pump body 48 is connected to the tank outlet 43. The main heating box 5 is installed on the main unit. The corresponding water outlet 43 of the box is connected to the corresponding water inlet of the main unit (left main water inlet 13, right main water inlet 14). The corresponding water inlet of the main unit (left main water inlet 13, right main water inlet 14) is connected to the first water inlet 53 of the main heating box 5. The first water outlet 51 of the main heating box 5 is connected to the corresponding first pump body 73. The first pump body 73 is connected to the corresponding two-position three-way solenoid valve 74 through the second circulation pipe 72. The two-position three-way solenoid valve 74 is connected to the first water outlet 51 through the first circulation pipe 71. The other passage of the two-position three-way solenoid valve 74 is connected to the water outlet of the coffee machine. The main components of the fully automatic micro-circulation temperature control system are connected and distributed.

[0032] Preheating Operation Control: After the coffee machine is installed and powered on, it enters the preheating state. Taking bottled water as an example, the fully automatic micro-circulation temperature control system operates as follows: When the main heating tank 5 and the auxiliary heating tank 6 detect a water shortage, the second pump 47 is activated. Bottled water is drawn into the second pump 47 through the corresponding bottled water inlet 42 of the water tank 4, and then pumped into the auxiliary heating tank 6 through the second inlet 62. When the second water level controller 67 of the auxiliary heating tank 6 detects water (the set water volume for the auxiliary heating tank 6), it provides a signal to the control system. The third pump 48 is then activated to pump water through the second outlet 61 of the auxiliary heating tank 6, allowing the water to flow to the corresponding tank outlet 43 of the water tank 4. Water is supplied to the main heating tank 5 via the main inlet pipe (left main inlet 13, right main inlet 14) from the first inlet 53. The first water level controller 57 of the main heating tank 5 detects water (the set water volume of the main heating tank 5) and provides a signal to the control system. The third pump 48 of the auxiliary heating tank 6 is closed, stopping the water supply to the main heating tank 5. While supplying water to the main heating tank 5, the second pump 47 continuously replenishes water to the auxiliary heating tank 6 until the second water level controller 67 of the auxiliary heating tank 6 continuously detects water and provides a signal to the control system. The second pump 47 is then closed, stopping the water supply to the auxiliary heating tank 6. When the first water level controller 57 of the main heating tank 5 detects water, the first heater 56 of the main heating tank 5 is activated, and the first pump 73 of the main heating tank 5 is activated. The two-position three-way solenoid valve 74 connected to the coffee machine's outlet valve is closed, and the second circulation pipe 72 connected to the main heating tank 5 is opened, forming a water circulation loop 7. This allows the water in the main heating tank 5 to circulate and heat, resulting in a more uniform and consistent water temperature with almost no deviation. Meanwhile, as the water is heated on one side and circulated in the water circulation loop 7, it also drives the cold water stored inside the components of the water circulation loop 7 to participate in the internal circulation, causing the components in the entire brewing pipeline system to be preheated until the temperature is the same and consistent with the setting.

[0033] When the water temperature reaches the preheating set temperature (e.g., 85 degrees Celsius), the first temperature sensor 55 sends a signal to the control system to shut off the first heater 56 and stop heating, while simultaneously shutting off the first pump 73 to stop water circulation. When the first temperature sensor 55 detects that the water temperature is 1 degree Celsius lower than the preheating set temperature, the first heater 56 is automatically turned on to heat the water, and the first pump 73 is started to begin water circulation. When the water temperature reaches the preheating set temperature (e.g., 85 degrees Celsius), the first temperature sensor 55 sends a signal to the control system to shut off the first heater 56 and stop heating and water circulation; this cycle continues indefinitely to maintain the automatic heat preservation state. When the second water level controller 67 of the auxiliary heating tank 6 detects water, and the second pump body 47 and the third pump body 48 are closed, the second heater 66 of the auxiliary heating tank 6 is activated to heat the water. When the water reaches the set temperature (e.g., 60 degrees Celsius), the automatic thermostat 65 disconnects the second heater 66 to stop heating. When the water temperature in the auxiliary heating tank 6 falls below the set temperature (e.g., 60 degrees Celsius), the automatic thermostat 65 automatically resets, and the second heater 66 of the auxiliary heating tank 6 continues to heat the water. When the water reaches the set temperature (e.g., 60 degrees Celsius), the automatic thermostat 65 disconnects, and the second heater 66 of the auxiliary heating tank 6 stops heating. This cycle continues until the automatic temperature is maintained. At this point, the coffee machine has preheated and is ready to brew coffee.

[0034] The coffee machine body provided in this solution features a heating system where the main heating chamber 5 and the auxiliary heating chamber 6 can be controlled independently. When the second water level controller 67 of the auxiliary heating chamber 6 detects water and the second pump 47 and the third pump 48 are off, the second heater 66 of the auxiliary heating chamber 6 automatically starts heating. When the water temperature reaches the set temperature (e.g., 60 degrees Celsius), the automatic thermostat 65 disconnects the second heater 66 to stop heating. When the water temperature in the auxiliary heating chamber 6 falls below the set temperature (e.g., 60 degrees Celsius), the automatic thermostat 65 automatically resets, and the second heater 66 of the auxiliary heating chamber 6 continues heating. When the water temperature reaches the set temperature (60 degrees Celsius), the automatic thermostat 65 disconnects, and the second heating element of the auxiliary heating chamber 6 stops heating. This cycle continues indefinitely, maintaining an automatic temperature control. This does not conflict with whether the main heating chamber 5 is running the coffee-making process. Therefore, the coffee machine body can preheat the water temperature in the auxiliary heating chamber 6 while the coffee-making process is running, improving the efficiency of coffee making.

[0035] Another embodiment, such as Figures 1-3 and Figure 9 As shown, the coffee machine body in this solution can also be used for a single water outlet arm 3. Similarly, it can also be used for a coffee machine body with multiple water outlet arms 3. It is only necessary to make corresponding adjustments according to the number of water outlet arms 3.

[0036] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
