Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, and in particular to a water supply structure that simulates hand-drip coffee. Background Technology

[0002] In current technology, most coffee machines have a drainage system where hot water drips from a fixed point onto the coffee grounds. As the hot water passes through the coffee grounds, the grounds mix and dissolve, carrying away some of the soluble substances, thus completing the coffee extraction. However, because the hot water flows through only one point, the soluble substances at that point are not replenished, and the soluble substances at other points are not effectively utilized, thus affecting the coffee extraction rate. Summary of the Invention

[0003] To address the problems with the drainage structure of existing coffee machines, this invention provides a drainage structure that simulates pour-over coffee, which can mimic the effect of pour-over coffee and improve the extraction rate of coffee.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A water supply structure simulating pour-over coffee, comprising:

[0006] A tray is provided with a water outlet, a turntable is provided on the tray, a tray cover is provided on the tray, and a water inlet is provided on the tray cover;

[0007] A water storage component is disposed on the turntable, and the water storage component is connected to the water inlet and the water outlet respectively;

[0008] A first drive component is disposed on the tray cover and is used to drive the water storage component to perform linear reciprocating motion;

[0009] The second drive assembly is disposed on the tray and is used to drive the turntable to rotate.

[0010] When hot water flows into the water storage component through the outlet, the first drive component drives the water storage component to perform linear reciprocating motion, while the second drive component drives the turntable to rotate, thereby simulating the effect of hand-washing.

[0011] As described above, the simulated pour-over coffee water supply structure further includes a water storage assembly comprising a water storage tank support, which is mounted on the turntable. The water storage tank support has a water storage tank, and the inlet and outlet are respectively connected to the water storage tank via pipes. The water storage tank support is provided with a guide rail, and the water storage tank is provided with a guide groove, which is adapted to the guide rail.

[0012] As described above, the simulated pour-over coffee water supply structure further includes a first drive component comprising a first motor, an output end of the first motor being provided with a first gear, a rack being provided on the water storage bracket, the rack being arranged along the length direction of the water storage tank, and the first gear being connected to the rack via a connecting member.

[0013] As described above, the water supply structure for simulating pour-over coffee further includes a double-row gear, which is connected to a first bearing located inside the tray cover. The double-row gear includes an upper gear and a lower gear, with the upper gear meshing with the first gear and the lower gear meshing with the rack.

[0014] As described above, the simulated pour-over coffee pouring structure further includes a receiving cavity on the tray cover, a double-row gear inside the receiving cavity, a top cover on the receiving cavity, and a water inlet on the top cover.

[0015] In the simulated pour-over coffee pouring structure described above, the second drive component further includes a second motor, the output end of which is provided with a second gear, and the turntable is provided with serrations, the second gear meshing with the serrations.

[0016] In addition to the water supply structure for simulating pour-over coffee as described above, a water-blocking cap is further provided on the water storage tank support.

[0017] In addition to the water supply structure for simulating pour-over coffee as described above, the turntable is further provided with a second bearing or ball bearing.

[0018] Compared with the prior art, the advantages of this invention are as follows:

[0019] 1. This invention uses dual motors to drive the water storage component to simultaneously complete linear reciprocating motion and constant-speed rotational motion, thereby simulating the professional pouring technique of a professional pour-over coffee maker, which involves pouring water in a circular motion "from the inside out and from the center to the edge". This overcomes the problem of fixed-point water pouring in traditional coffee machines, greatly improving the extraction rate of coffee and resulting in coffee with a richer and fuller flavor profile. It is suitable for the high-precision extraction scenarios of fully automatic coffee machines.

[0020] 2. This invention uses a bearing or ball bearing structure inside the turntable to reduce rotational friction resistance, ensuring smooth and stable operation of the entire machine. At the same time, the transmission components such as the double-row gears and the first bearing are sealed in the closed cavity of the tray cover, effectively isolating moisture erosion and coffee residue contamination. Combined with the water baffle cap on the top of the water tank support to prevent water splashing, the water filling process is always concentrated and controllable, greatly extending the long-term service life of the entire machine.

[0031] Example:

[0032] This invention provides a water supply structure simulating pour-over coffee, relating to the field of coffee machine technology. It includes a tray 1, a water storage component, a first drive component, and a second drive component. The water storage component is supported by a turntable 2 on the tray 1. Hot water is continuously injected through an inlet 18 on the tray cover 3, flowing through a pipe into a water storage tank 5 and then out through an outlet 19. A rack 8 is provided on the inner wall of the water storage tank 5. A first motor 6 in the first drive component drives a first gear 7, which, through the transmission of a double-row gear 9 (the upper gear of the double-row gear 9 meshes with the first gear 7, and the lower gear of the double-row gear 9 meshes with the rack 8), causes the water storage tank 5 to reciprocate linearly on a water storage tank support 4. Simultaneously, a second motor 11 in the second drive component, through a second gear 12 at its output end, meshes with the serrations 13 on the edge of the turntable 2, driving the entire turntable 2 to rotate at a constant angular velocity, thus causing the movement trajectory of the water storage component to spread in a spiral pattern. The turntable 2 is equipped with a second bearing 15 or a ball bearing structure, which can effectively reduce rotational friction resistance and make the turntable 2 operate more smoothly. The water deflector 14 on the top of the water storage tank bracket 4 can prevent water from splashing and maintain the concentrated flow of water.

[0033] In addition, in this embodiment, the first motor 6 is a stepper motor, and the second motor 11 is a geared motor. The first motor 6, being a stepper motor, ensures that the linear reciprocating motion of the water tank 5 is constant in speed and precise in position control. The second motor 11, being a geared motor, can stably output large torque, thereby maintaining the turntable 2 rotating smoothly at a constant low angular velocity. The coordinated operation of the two motors allows the spiral diffusion motion trajectory of the water storage component to be uniform and controllable, accurately replicating the water pouring effect of hand-drip coffee.

[0034] The entire water inlet structure is integrated into the interior of the coffee machine. The tray cover 3 has a receiving cavity 16, which is sealed by the top cover 17. The double-row gears 9 and the first bearing 10 are both sealed within the receiving cavity 16 to prevent moisture corrosion and coffee residue contamination, ensuring long-term operational reliability. During operation, hot water enters the water storage component through the inlet 18. Driven by both the first motor 6 and the second motor 11, the hot water simultaneously moves in a straight line and rotates within the water inlet structure, simulating the circular pouring technique of a professional pour-over coffee maker, moving the water "from the inside out and from the center to the edge." Compared to the traditional fixed-point water inlet method of coffee machines, this water inlet structure significantly improves the coffee extraction rate, resulting in coffee with a richer flavor profile. Furthermore, it requires no manual intervention and is suitable for the high-precision extraction scenarios of fully automatic coffee machines.
