Description

Technical Field

[0001] This utility model relates to the field of coffee machine grinding and cooling technology, specifically to a low-temperature grinding and cooling structure for coffee machines. Background Technology

[0002] A coffee machine is an appliance or device used to make coffee. It can extract flavor compounds from coffee by bringing hot water into contact with coffee grounds through different extraction methods, and finally make various types of coffee drinks. The coffee machine first grinds and crushes the coffee beans by using a motor to drive the grinding disc to crush the coffee beans. The ground coffee powder automatically falls into the brewing head or filter cup.

[0003] When coffee is being ground, the internal grinding disc comes into contact with the coffee beans. Due to friction during grinding, the temperature inside the grinding chamber rises. Prolonged grinding leads to a high internal temperature, which can affect the ground coffee powder and the taste of the brewed coffee. Most coffee machines have poor heat dissipation, resulting in poor quality coffee after grinding. Summary of the Invention

[0004] In order to overcome the poor grinding and cooling mechanism of existing coffee machines, which affects the grinding effect of coffee, this utility model provides a low-temperature grinding and cooling structure for coffee machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-temperature grinding and cooling structure for a coffee machine, including a body, a grinding chamber fixedly installed inside the body, a heat dissipation ring adhered to the outside of the grinding chamber, a liquid storage pipe fixedly installed outside the heat dissipation ring, heat absorption plates fixedly installed at both ends of the liquid storage pipe, a fan fixedly installed on the side of the heat absorption plate by bolts, a bean storage bin fixedly installed at the top of the body, and a heat absorption rod fixedly installed inside the bean storage bin.

[0006] The aforementioned low-temperature grinding and cooling structure of the coffee machine has a control panel fixedly installed on the side of the machine body, a powder storage compartment movably installed at the lower end of the machine body, and heat dissipation vents on both sides of the machine body.

[0007] In the aforementioned low-temperature grinding and cooling structure of the coffee machine, an ice storage compartment is fixedly installed at the top of the bean storage compartment. The ice storage compartment is connected to a heat-absorbing rod, and the interior of the heat-absorbing rod is hollow.

[0008] In the aforementioned low-temperature grinding and cooling structure of the coffee machine, multiple heat-conducting rods are embedded inside the heat dissipation ring, a heat collection plate is fixedly installed at the lower end of the heat-conducting rods, and multiple heat dissipation fins are welded to the lower end of the heat collection plate.

[0009] In the aforementioned low-temperature grinding and cooling structure of the coffee machine, a motor is fixedly installed at the lower end of the grinding chamber, and the motor is fixedly installed at the bottom end of the grinding chamber via a mounting bracket.

[0010] In the aforementioned low-temperature grinding and cooling structure of the coffee machine, a rotating rod is fixedly installed at the output end of the motor, a rotating block is fixedly installed on the outside of the rotating rod, and grinding rods are symmetrically installed on both sides of the rotating block.

[0011] In the aforementioned low-temperature grinding and cooling structure of the coffee machine, a stabilizing rod is fixedly installed at the top of the motor, and one end of the stabilizing rod is movably embedded in the inner wall of the grinding chamber.

[0012] This utility model provides a low-temperature grinding and cooling structure for a coffee machine, which has the following beneficial effects:

[0013] This invention features a coffee machine grinding and cooling mechanism with improved cooling performance. The coffee machine has an internal grinding chamber with a heat dissipation ring tightly fitted to its exterior. Multiple heat dissipation rods are embedded within the heat dissipation ring, each connected to a heat collection plate at the bottom. The heat dissipation ring is made of copper sheet, effectively absorbing heat.

Deionized water has a high specific heat capacity, absorbing a large amount of heat. Both ends of the liquid storage tube are connected to heat dissipation plates inside the heat dissipation vents on both sides. Fans are installed on the sides of the heat dissipation plates to continuously dissipate heat, keeping the liquid temperature inside the storage tube low and continuously absorbing heat from the grinding chamber. A hollow heat-absorbing rod is installed inside the top storage chamber, inserted into the coffee beans to absorb heat and keep them at a low temperature. The upper end of the heat-absorbing rod is connected to an ice chamber, which stores a large amount of ice to continuously cool the coffee beans, reducing the temperature generated during grinding.

[0021] Please see Figure 1-5 This utility model provides a solution: a low-temperature grinding and cooling structure for a coffee machine, including a body 1. A grinding chamber 8 is fixedly installed inside the body 1 to grind coffee beans added inside. A heat dissipation ring 14 is adhered to the outside of the grinding chamber 8. The heat dissipation ring 14 is made of copper metal and has good heat absorption and dissipation effects. A liquid storage pipe 9 is fixedly installed outside the heat dissipation ring 14. The front part of the liquid storage pipe 9 stores deionized water and preservatives, which has a high specific heat capacity and absorbs the heat emitted by the heat dissipation ring 14. Heat absorption plates 17 are fixedly installed at both ends of the liquid storage pipe 9. The heat absorption plates 17 absorb the heat absorbed by the liquid inside the liquid storage pipe 9. A fan 16 is fixedly installed on the side of the heat absorption plate 17 by bolts. The fan 16 then dissipates the heat absorbed by the heat absorption plate 17, keeping the temperature inside the grinding chamber 8 low. A bean storage chamber 3 is fixedly installed at the top of the body 1. A heat absorption rod 7 is fixedly installed inside the bean storage chamber 3. An ice storage chamber 4 stores ice. The heat absorption rod 7 absorbs the heat from the coffee beans, and the ice cancels out the absorbed heat.

[0022] In this embodiment, a control panel 2 is fixedly installed on the side of the machine body 1 to control the operation of the machine body 1. A powder storage compartment 5 is movably installed at the lower end of the machine body 1 to store the ground coffee powder. Heat dissipation vents 6 are provided on both sides of the machine body 1 to better dissipate heat. An ice storage compartment 4 is fixedly installed at the top of the bean storage compartment 3. The ice storage compartment 4 is connected to the heat absorption rod 7. The heat absorption rod 7 is hollow inside. The ice blocks cancel out the heat of the heat absorption rod 7. At the same time, the melted ice water is stored inside the heat absorption rod 7 to absorb a certain amount of heat. Multiple heat conduction rods 15 are embedded inside the heat dissipation ring 14. A heat collection plate 10 is fixedly installed at the lower end of the heat conduction rod 15 to assist in heat absorption. The heat absorbed is then further dissipated through multiple heat dissipation fins 11 welded to the lower end of the heat collection plate 10.

[0023] In this embodiment, a motor 12 is fixedly installed at the lower end of the grinding chamber 8. The motor 12 is fixedly installed at the bottom end of the grinding chamber 8 through a mounting bracket 13. The motor 12 outputs power to drive the upper grinding rod 21 to grind the coffee beans. A rotating rod 18 is fixedly installed at the output end of the motor 12. A rotating block 19 is fixedly installed on the outside of the rotating rod 18. Grinding rods 21 are symmetrically installed on both sides of the rotating block 19 to perform linkage operation, increase the stability of the grinding rods 21 during rotation, and perform better grinding operation. A stabilizing rod 20 is fixedly installed at the top of the motor 12. One end of the stabilizing rod 20 is movably embedded in the inner wall of the grinding chamber 8. The stabilizing rod 20 increases the stability of the rotating rod 18 during rotation. Coffee beans have a certain hardness, and grinding will produce a certain vibration. The stabilizing rod 20 enhances the grinding effect.
