Abstract
Description
Technical Field
[0001] This utility model relates to a heat dissipation structure for a coffee roaster. Background Technology
[0002] A coffee roaster is a device used to roast coffee beans. During the roasting process, the roaster generates a lot of heat, which radiates outward through the roasting chamber. Since the roasting chamber is enclosed by the casing, ventilation structures and cooling fans need to be installed on the casing for heat dissipation. The roasting process also requires exhaust fans to remove smoke. Therefore, a roaster must be equipped with at least a cooling fan and an exhaust fan, which leads to problems such as high production costs and the occupation of internal space in the roaster.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes a heat dissipation structure for a coffee roaster, which can effectively reduce the production cost of the roaster.
[0005] This utility model proposes a heat dissipation structure for a coffee roaster, which includes an inner shell located inside the machine body, forming a roasting cavity. An installation area is formed between the back of the inner shell and the back of the machine body. A circuit board module is located in the installation area. A ventilation structure is provided on the machine body to connect the installation area with the outside. The ventilation structure corresponds to the circuit board module. The installation area is provided with a smoke exhaust mechanism, which includes a smoke exhaust pipe, a smoke guide pipe, and a fan. The smoke exhaust pipe is connected to the roasting cavity. The smoke guide pipe is arranged around the periphery of the smoke exhaust pipe, and the output end of the smoke guide pipe extends out of the installation area. An air passage is formed between the smoke guide pipe and the smoke exhaust pipe. The air outlet of the fan is connected to the air passage, and the air inlet of the fan is located in the installation area.
[0006] In one or more embodiments, the smoke guide pipe is provided with an air duct that connects to an air passage, and the fan is installed on the air inlet end of the air duct.
[0007] In one or more embodiments, the exterior of the body is provided with a smoke collection shell, the top of the smoke collection shell is provided with a smoke exhaust port, and the smoke guide pipe is connected to the smoke collection shell.
[0008] In one or more embodiments, an air purifier is connected to the exhaust port.
[0009] In one or more embodiments, the baking cavity is provided with a baking cage, and the installation area is provided with a drive device for driving the baking cage to rotate.
[0010] In one or more embodiments, the ventilation structure is a ventilation grille.
[0011] Compared with existing technologies, this solution has the following advantages: the heat dissipation structure can eliminate the need for a cooling fan, and the exhaust mechanism can draw away the hot air in the installation area while working, allowing the outside cold air to enter through the ventilation structure to dissipate heat from the circuit board module. At the same time, the exhaust mechanism can also exhaust smoke from the baking chamber. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of the baking machine of this utility model;
[0013] Figure 2 This is a schematic diagram of the installation area of this utility model. Detailed Implementation
[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0015] Please refer to the appendix. Figure 1-2 This utility model provides a heat dissipation structure for a coffee roaster, comprising an inner shell 2 located inside a body 1, forming a roasting cavity. An installation area is formed between the back of the inner shell 2 and the back of the body, and a circuit board module 3 is located within the installation area. A ventilation structure 4, corresponding to the circuit board module 3, is provided on the body 1, connecting the installation area to the outside. The installation area is equipped with a smoke exhaust mechanism, which includes a smoke exhaust pipe 5, a smoke guide pipe 6, and a fan 7. The smoke exhaust pipe 5 communicates with the roasting cavity, and the smoke guide pipe 6 surrounds the periphery of the smoke exhaust pipe 5, with its output end extending out of the installation area. An air passage is formed between the smoke guide pipe 6 and the smoke exhaust pipe 5. The fan 7... The fan 7 has an air inlet located in the installation area, and its outlet is connected to the air duct. When the fan blows air through the air duct, the air pressure in the air duct decreases, while the air pressure in the exhaust pipe is higher. Under this pressure difference, the air inside the baking chamber connected to the exhaust pipe is discharged outward from the exhaust pipe, thus guiding and discharging the smoke. In addition, since the fan's air inlet is located in the installation area, it can draw away the hot air from the installation area, while cold air from the outside is input through the ventilation structure and blown toward the circuit board module, thereby cooling the circuit board module. The ventilation structure is preferably a ventilation grille.
[0016] The smoke guide pipe 6 is equipped with an air duct 8, which is connected to the air passage. The fan 7 is installed on the air inlet end of the air duct 8. Since the smoke guide pipe is connected to the baking chamber, the smoke guide pipe has a certain temperature. By setting the air duct to install the fan, the fan can be prevented from being affected by high temperature.
[0017] The outer surface of the body 1 is equipped with a smoke collection shell 9, and the top of the smoke collection shell 9 is equipped with a smoke exhaust port 10. The smoke guide pipe 6 is connected to the smoke collection shell 9. Since the flue gas carries bean husks, dust, etc., the smoke collection shell can collect bean husks and dust. The smoke exhaust port is used to connect to the smoke exhaust pipe. In order to purify the flue gas, an air purifier is connected to the smoke exhaust port. The air purifier can use activated carbon to purify the air.
[0018] The baking chamber is equipped with a baking cage, and the installation area is equipped with a drive device 11 for driving the baking cage to rotate. The baking cage is equipped with a heating tube for heating, and the drive device specifically includes a motor and a gearbox.
[0019] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
