Description

Technical Field

[0001] This invention relates to a coffee brewing apparatus, and more particularly to an automatic rotating water dispensing coffee component and coffee machine. Background Technology

[0002] Currently, most coffee brewing equipment and water outlets on the market use either direct flow or spray flow, which affects the brewing results. Furthermore, professional coffee is made manually, a process that demands a high level of skill and can be limited by consumer preferences. To enjoy delicious coffee and achieve the same quality as manually brewed coffee, the market needs a coffee machine that can deliver the same results. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic rotating water dispensing coffee component and coffee machine. The technical problem to be solved is that it is convenient to use and simple to operate, while also simulating manual coffee brewing.

[0004] To solve the above problems, the present invention adopts the following technical solution: an automatic rotating water-dispensing coffee assembly, including a water wheel chamber, a spray chamber below the water wheel chamber, and a coffee filter cup chamber below the spray chamber. A water wheel is provided in the water wheel chamber, and a water dispenser is provided on the water wheel chamber. The water wheel includes a rotating shaft and a blade. The water wheel and the spray arm are fixedly connected by the rotating shaft. The water outlet of the water dispenser is opposite to the blade of the water wheel. Both the rotating shaft and the spray arm are hollow structures. The rotating shaft is positioned near the lower end of the blade. It is equipped with a drain hole that is connected to the inner cavity of the rotating shaft. The part of the rotating shaft located in the spray arm has a water inlet hole so that the inner cavity of the rotating shaft is connected to the inner cavity of the spray arm. There are spray holes on the lower surface of the spray arm. When the water flows out of the water outlet and sprays onto the blade, the force of the water flow drives the water wheel to rotate. At the same time, the water also flows into the spray arm through the drain hole on the rotating shaft and flows out from the spray holes. The spray arm is driven to rotate by the water wheel to form a rotating spray of water into the coffee filter cup chamber.

[0005] Furthermore, the water turbine also includes a base plate and a wheel cap. The blades are arranged in a ring on the base plate with the rotating shaft as the center. The rotating shaft passes through the base plate. The water outlet is set between two adjacent blades. The blades are fixed on the base plate. The wheel cap is located at the upper end of the rotating shaft.

[0006] Furthermore, the water turbine also includes a top plate, which is fixed to the upper end of the blade, the upper end of the rotating shaft passes through the top plate, and the wheel cap is fixed to the upper end of the rotating shaft that extends out of the top plate.

[0007] Furthermore, the bottom plate has a raised water-blocking flange on its edge so that water flows out preferentially from the spray arm.

[0008] Furthermore, the bottom of the water turbine chamber is provided with evenly distributed drainage holes so that water in the water turbine chamber can flow into the spraying chamber through the drainage holes. During the rotation of the spraying arm, the water entering the spraying chamber through the drainage holes is blocked, forming a secondary rotation spraying.

[0009] Furthermore, a fixing sleeve is provided between the rotating shaft and the bottom of the turbine chamber.

[0010] Furthermore, a washer is provided at the lower end of the water wheel, and the washer is fitted onto the rotating shaft.

[0011] Furthermore, a gap is provided between the washer and the bottom of the water turbine chamber, and a ball bearing is provided in the gap. The ball bearing is arranged in a circle around the rotating shaft, and the ball bearing contacts the washer and the bottom of the water turbine chamber respectively.

[0012] Furthermore, the fixed sleeve has a top plane around its perimeter, which abuts against the bottom of the water turbine chamber, and the ball bearings are located above and in contact with the top plane.

[0013] The present invention also provides a coffee machine, including a coffee filter cup chamber, a water tank, and the aforementioned automatic rotating water dispensing coffee component, which is disposed above the coffee filter cup chamber and the water dispenser is connected to the water dispensing component of the water tank.

[0014] Compared with existing technologies, this invention, by setting a water wheel in the water wheel chamber and connecting the water wheel to the spray arm in the spraying chamber via a rotating shaft, uses the force of the water flow to drive the water wheel to rotate, thereby rotating and blocking the water flowing out of the water leakage hole in the water wheel chamber to create a rotating spraying effect, simulating the brewing process of hand-drip coffee. It is not only convenient to operate but also has a simple structure. Since no manual brewing is required, it avoids the problem of coffee powder coagulation caused by manual operation. By simulating manual coffee brewing through the spray arm, no electricity is required, thus saving costs and energy. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 6 As shown, this invention discloses an automatic rotating water-dispensing coffee assembly, including a water wheel chamber 1 and a spraying chamber 2 disposed below the water wheel chamber 1. The water wheel chamber 1 contains a water wheel 102, and the bottom of the water wheel chamber 1 has a drain hole 111. A water dispenser 506 is disposed on the peripheral wall of the water wheel chamber 1. A spraying arm 201 is disposed in the spraying chamber 2. The water wheel 102 includes a rotating shaft 103 and a blade 109. The lower end of the rotating shaft 103 passes through a shaft hole at the bottom of the water wheel chamber 1 and connects to the spraying arm 201. The water wheel 102 is located in the middle of the water wheel chamber 1. The water dispenser 506 passes through the side wall of the water wheel chamber 1 and is opposite to the blade 109 of the water wheel 102. Both the rotating shaft 103 and the spraying arm 201 are hollow structures. A drain hole 108 is provided near the lower end of the blade 109 on the rotating shaft 103. More precisely, the drain hole 108 is located on the circular plate near the lower end. The drain hole 108 communicates with the inner cavity of the rotating shaft 103. A water inlet hole 2012 is provided on the part of the rotating shaft 103 located in the spray arm 201 so that the inner cavity of the rotating shaft 103 communicates with the inner cavity of the spray arm 201. A spray hole 2011 is provided on the surface of the end of the spray arm 201 away from the water wheel chamber 1 so that after part of the water flows into the inner cavity of the rotating shaft 103 through the drain hole 108, it flows into the inner cavity of the spray arm 201 through the water inlet hole 2012 and flows out from the spray hole 2011 during the rotation of the spray arm 201, forming a rotating spray. When water flows out of the water outlet 506 and sprays onto the blades 109 of the water wheel 102, the force of the water flow drives the water wheel 102 to rotate. The rotation of the water wheel 102 drives the spray arm 201 to rotate. At the same time, during the rotation, the spray arm 201 blocks the water entering the spray chamber 2 through the drain hole 111. Because the spray arm 201 blocks the water, a secondary rotational spray is formed when it rotates.

[0023] like Figure 1-5 As shown, in one embodiment of the present invention, the waterwheel 102 is circular and also includes a base plate 101. The blades 109 are arranged in a ring on the base plate 101 with the rotating shaft 103 as the center. The rotating shaft 103 passes through the base plate 101. The drain hole 108 is provided between two adjacent blades 109. The blades 109 are fixed on the base plate 101. The wheel cap 1031 is provided at the upper end of the rotating shaft 103.

[0024] like Figure 6 As shown, in another embodiment of the present invention, based on the above-mentioned water turbine 102, the water turbine 102 further includes a top plate 112, the top plate 112 is fixed to the upper end of the blade plate 109, the upper end of the rotating shaft 103 passes through the top plate 112, and the wheel cap 1031 is fixed to the upper end of the rotating shaft 103 that passes through the top plate 112.

[0025] like Figure 4 and Figure 6 As shown, based on the two embodiments described above, a water-blocking flange 113 is provided on the edge of the circumferential end face of the base plate 101 so that water flows out preferentially from the spray arm 201.

[0026] In the two embodiments described above, the blade 109 can also be an arc-shaped plate.

[0027] like Figure 1 As shown, the water spraying chamber 2 is a hollow shell with openings at both the top and bottom, and the water spraying chamber 2 has the function of preventing water from splashing.

[0028] like Figure 1 and Figure 2 As shown, the water turbine chamber 1 is a hollow cylinder with a closed lower end and an openable water turbine chamber cover 104 at the upper end, so as to enable cleaning of the water turbine chamber 1.

[0029] like Figure 1 and Figure 3 As shown, the spray arm 201 is rectangular, and its center is connected to the rotating shaft 103. The spray holes 2011 are evenly spaced along the length of the spray arm 201.

[0030] like Figure 5 As shown, based on the above structure, a fixing sleeve 106 is provided between the rotating shaft 103 and the bottom shaft hole of the water turbine chamber 1 to achieve a seal between the rotating shaft 103 and the bottom shaft hole of the water turbine chamber 1.

[0031] like Figure 5 As shown, a washer 105 is provided at the lower end of the water turbine 102, and the washer 105 is fitted onto the rotating shaft 103. Furthermore, a gap is provided between the washer 105 and the bottom of the water turbine chamber 1, and a ball bearing 107 is provided in the gap. The ball bearing 107 is arranged in a circle around the rotating shaft 103, and the ball bearing 107 contacts both the washer 105 and the bottom of the water turbine chamber 1 to improve the smoothness of the rotation of the water turbine 102.

[0032] Preferably, such as Figure 5 As shown, the fixed sleeve 106 has a top plane 1061 around its perimeter. The top plane 1061 abuts against the edge of the bottom shaft hole of the water turbine chamber 1. The ball bearing 107 is located above the top plane 1061 and in contact with the top plane 1061.

[0033] like Figure 1As shown, the present invention also discloses a coffee machine, including a base 5 and a water tank 6. The water tank 6 is disposed on the base 5. On one side of the base 5 (left side in the figure), a coffee cup 4 and a coffee filter cup 3 are arranged sequentially from bottom to top. Above the coffee filter cup 3, the aforementioned automatic rotating water dispensing coffee assembly is disposed. A water spraying chamber 2 is disposed directly above the coffee filter cup 3. A coffee filter cup 301 is disposed in the coffee filter cup 3. The water spraying chamber 2 and the water wheel chamber 1 are fixed on the base 5. The coffee cup 4 can be removed at any time. The base 5 has a receiving cavity 501, in which a water pump 503 and a heater 505 are disposed. The water outlet of the water pump 503 is connected to... The water inlet of the heater 505 is connected to the second water pipe 504. The outlet of the heater 505 is connected to the inlet of the water dispenser 506 via the third water pipe 507. The inlet of the water pump 503 is connected to the water guide seat 508 on the base 5 via the first water pipe 502. A water outlet switch 601 is provided at the bottom of the water tank 6. The water outlet switch 601 is a water valve. A water tank cover 602 that can be opened is provided at the top of the water tank 6 for adding clean water. The coffee machine also includes a power supply and a control board (not shown in the figure). The control board is equipped with function buttons. The control board is connected to control the water pump 503, the heater 505, etc. In this invention, the water dispenser 506 is a pipe.

[0034] The working principle of this invention is as follows:

[0035] After the coffee machine is powered on, pressing the "Start / Stop" button on the function keys activates the water pump 503, which begins pumping water. Water from the water tank 6 enters the water guide seat 508 on the base 5 through the water outlet switch 601 at the bottom of the water tank 6. The water then passes through the water guide seat 508 and the first water pipe 502 into the water pump 503. The water is then pumped by the water pump 503 through the second water pipe 504 into the heater 505. The heated water from the heater 505 enters the water outlet 506 through the third water pipe 507, and flows out through the water outlet 506. The water dispenser 506 is opposite to the impeller 109 of the water wheel 102. Hot water is sprayed onto the impeller 109, and the force of the hot water drives the water wheel 102 to rotate. As the water continuously hits the impeller 109, it flows into the inner cavity of the rotating shaft 103 through the drain hole 108 located at the center of the water wheel. The water flows downward along the inner cavity of the rotating shaft 103 and flows into the spray arm 201 from the inlet hole 2012. The hot water entering the spray arm 201 flows out through the spray hole 2011 and sprays onto the coffee grounds on the coffee filter cup 301 below the spray chamber 2. Since the water wheel 102 rotates continuously under the drive of the hot water, the spray arm 201 also rotates. Therefore, the water sprayed from the spray arm 201 is sprayed onto the coffee grounds in the coffee filter cup 301 in a rotating manner. At the same time, during the rotation, the spray arm 201 blocks the water entering the spray chamber 2 through the drain hole 111, forming a secondary rotating spray. This completes the entire coffee brewing process of the automatic rotating water dispenser. If you need to stop the process, simply press the start / stop button.

[0036] This invention can avoid the situation where the coffee powder solidifies during brewing due to human operation, thus affecting the brewing effect and failing to meet consumer needs; at the same time, it also has the advantages of convenient and professional operation, safety, low cost of use, and high reliability.
