Description

Technical Field

[0001] This invention relates to the field of tea drying technology, and in particular to a tea drying device and its control method. Background Technology

[0002] As people's living standards improve, tea has become a daily beverage for many families. Consumers often store various types of tea at home to meet different drinking needs. However, due to the temperature and humidity fluctuations in the home storage environment, tea is very susceptible to absorbing moisture from the air and becoming damp, which affects the taste after brewing. Therefore, it is necessary to dry damp tea.

[0003] Currently, simple drying devices are commonly used in households. These devices typically employ a fixed design, meaning the container for holding the tea is permanently installed inside the drying chamber. During the drying process, the tea leaves piled up in the container cannot be heated sufficiently, resulting in uneven heating of the tea leaves in different locations. This can easily lead to localized over-drying or incomplete drying, making it difficult to ensure consistent quality of the dried tea and resulting in poor drying effects. Furthermore, because the tea container is fixed in place, users need to disassemble it after drying, which is inconvenient and negatively impacts the user experience.

[0004] Therefore, there is an urgent need for a tea drying device and its control method to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a tea drying device and its control method, which can improve the uniformity and efficiency of tea drying, ensure the drying effect of tea, simplify the tea drying operation steps, and improve the user experience.

[0009] As an optional embodiment of the tea drying device of the present invention, the support includes a support plate, and a stop structure is provided on the support plate along the circumferential direction. The stop structure surrounds a limiting area on the support plate, and the tea basket is located within the limiting area.

[0010] As an optional embodiment of the tea drying device of the present invention, the housing is provided with a first mounting cavity communicating with the drying chamber, the heating module includes a heating coil, and the drying fan and the heating coil are spaced apart in the first mounting cavity along the airflow direction; The housing is provided with a second mounting cavity. The tea drying device also includes a cooling fan and a second driving component. Both the cooling fan and the second driving component are located in the second mounting cavity. The output end of the second driving component is connected to the cooling fan and / or the drying fan. The cooling fan can discharge the gas in the second mounting cavity to the external environment.

[0011] As an optional embodiment of the tea drying device of the present invention, the tea drying device further includes an exhaust housing, which has a first inlet, a second inlet and an exhaust port. The first inlet is connected to the first mounting cavity, the second inlet is connected to the second mounting cavity, and the exhaust port is connected to the external environment.

[0012] As an optional embodiment of the tea drying device of the present invention, the housing includes an inner shell and an outer shell covering the inner shell, wherein the inner shell defines the drying chamber; One side wall of the inner housing is provided with an opening, and an air duct shell is provided at the opening, the air duct shell defining the first mounting cavity; The outer shell and the inner shell define the second mounting cavity, and the outer shell has a plurality of vent holes in the area opposite to the cooling fan.

[0013] As an optional embodiment of the tea drying device of the present invention, a protective net is provided between the first mounting cavity and the drying chamber; And / or, a mounting bracket is provided in the second mounting cavity, and the second driving component is fixed to the mounting bracket.

The drying device is then activated, activating the drying fan and heating module. Simultaneously, the support rotates the tea basket, and the drying fan generates airflow that flows through the heating module to form hot air. This hot airflow blows onto the rotating tea basket within the drying chamber and enters the basket through its vents, allowing the hot airflow to contact the tea leaves and dry them. Because the tea basket is constantly rotating during the drying process, the hot airflow can enter the basket from any vent on its outer perimeter, ensuring that tea leaves at any position within the basket are fully in contact with the hot airflow. This improves the uniformity of heating, enhances the drying uniformity and efficiency, and guarantees the drying effect and the final brewed taste of the tea.

[0021] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0024] Example 1 This embodiment provides a tea drying device that can improve the uniformity and efficiency of tea drying, ensure the drying effect of tea, simplify the tea drying operation steps, and improve the user experience.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the tea drying device includes a housing 1, a support 2, a tea basket 3, and a drying assembly 4. The housing 1 is provided with a drying chamber 111. The support 2 is rotatably disposed in the drying chamber 111. The tea basket 3 is detachably placed on the support 2 and is used to hold the tea leaves to be dried. The tea basket 3 is provided with multiple ventilation holes 31. The drying assembly 4 includes a drying fan 41 and a heating module 42. The drying fan 41 is used to introduce airflow into the drying chamber 111, and the heating module 42 is located in the flow path of the airflow generated by the drying fan 41 and is used to heat the airflow generated by the drying fan 41.

[0026] The tea drying device provided in this embodiment allows the user to place damp tea leaves into a tea basket 3 and then place the tea basket 3 on a support 2 inside the drying chamber 111. The device is then activated, causing the drying fan 41 and heating module 42 to operate. Simultaneously, the support 2 rotates the tea basket 3, and the airflow generated by the drying fan 41 flows through the heating module 42 to form a hot airflow. This hot airflow blows onto the rotating tea basket 3 inside the drying chamber 111 and enters the basket 3 through the ventilation holes 31, allowing the hot airflow to contact the tea leaves and dry them. Because the tea basket 3 is constantly rotating during the drying process, the hot airflow can enter the basket 3 from any ventilation hole 31 on its outer periphery, ensuring that tea leaves at any position within the basket 3 are fully in contact with the hot airflow. This improves the uniformity of heating, enhances the drying uniformity and efficiency, and guarantees the drying effect and the final brewed taste of the tea.

[0027] Furthermore, since the tea basket 3 can be detachably placed on the support 2, users can directly place the tea basket 3 on or remove it from the support 2 when using the tea drying device, without the need to fix or disassemble the tea basket 3. This simplifies the tea drying process and improves the user experience.

[0028] Optionally, see Figure 4 , Figure 5 and Figure 6 The bottom of the tea basket 3 is provided with a ventilation hole 31, and the support base 2 and / or the tea basket 3 are provided with a support structure 32. The support structure 32 supports the bottom of the tea basket 3 and the support base 2, so that a preset gap 33 is maintained between the bottom of the tea basket 3 and the support base 2. This arrangement allows hot air to flow through the preset gap 33 between the bottom of the tea basket 3 and the support base 2 during the tea drying process. In turn, the hot air can enter the tea basket 3 through the ventilation hole 31 at the bottom of the tea basket 3 to come into contact with the tea leaves, further ensuring that the tea leaves in the tea basket 3 are fully in contact with the hot air, improving the uniformity of heating of the tea leaves, and enhancing the drying efficiency and drying effect of the tea leaves.

[0029] In this embodiment, the bottom of the tea basket 3 is provided with the aforementioned support structure 32. When the tea basket 3 is placed on the support seat 2, the bottom of the tea basket 3 maintains a preset gap 33 between itself and the support seat 2 through the support structure 32.

[0030] For example, the support structure 32 can be a support protrusion protruding from the bottom of the tea basket 3. Multiple support protrusions are spaced apart to ensure the stability of the tea basket 3 on the support 2. For example, three support protrusions can be provided at the bottom of the tea basket 3 to form a triangular support, which provides more stable support.

[0031] Optionally, the support protrusion can be integrally molded with the tea basket 3 for easy processing. Alternatively, the support protrusion can be installed separately at the bottom of the tea basket 3.

[0032] In other alternative embodiments, a support structure 32 may be provided on the support base 2, so that when the tea basket 3 is placed on the support base 2, it contacts the support structure 32 to form a preset gap 33. Alternatively, a support structure 32 may be provided at the bottom of both the support base 2 and the tea basket 3.

[0033] Optionally, see Figure 4 , Figure 7 and Figure 8 The tea drying device also includes a first driving component 5. The output end of the first driving component 5 is equipped with a support base 51. The support base 2 is detachably connected to the support base 51. The first driving component 5 can drive the support base 51 to rotate the support base 2 and the tea basket 3. When the tea drying device is working, the first driving component 5 drives the support base 51 to rotate the support base 2, thus ensuring that the tea basket 3 is always rotating during the drying process, guaranteeing even heating of the tea leaves inside the basket 3. Because the support base 2 is detachably connected to the support base 51, the support base 2 can be removed from the drying chamber 111 later, facilitating cleaning. For example, tea leaves debris in the tea basket 3 may fall onto the support base 2 through the vent 31; the support base 2 can be removed to clean the tea leaves debris, reducing the difficulty of cleaning and maintenance.

[0034] Optionally, see Figure 7 and Figure 8 One of the support base 51 and the support seat 2 is provided with a first limiting structure 23, and the other is provided with a second limiting structure 511. The support seat 2 is limited and fixed to the support base 51 by the engaging engagement of the first limiting structure 23 and the second limiting structure 511. The engaging of the first limiting structure 23 and the second limiting structure 511 allows the support seat 2 to rotate stably with the support base 51, providing a stable support base for the tea basket 3. At the same time, the engaging mechanism allows for easy assembly and disassembly of the support seat 2 without the need for tightening and loosening operations.

[0035] In this embodiment, as Figure 7As shown, the first limiting structure 23 includes a first engaging member 231 and a second engaging member 232 arranged at an angle, as... Figure 8 As shown, the second limiting structure 511 includes a first slot 5111 and a second slot 5112 arranged at an angle. A first engaging member 231 is engaged in the first slot 5111, and a second engaging member 232 is engaged in the second slot 5112. When installing the support 2, simply engage the first engaging member 231 and the second engaging member 232 with the first slot 5111 and the second slot 5112 respectively. When removing the support 2, simply lift the support 2 to disengage the first engaging member 231 and the second engaging member 232 from the first slot 5111 and the second slot 5112. The disassembly and assembly are convenient.

[0036] Meanwhile, the cooperation of the first locking component 231, the second locking component 232 with the first locking slot 5111 and the second locking slot 5112 can circumferentially limit the position of the support seat 2 on the support seat 51, so that the support seat 2 cannot rotate relative to the support seat 51, ensuring that the support seat 2 can rotate stably with the support seat 51, and providing a stable bearing foundation for the tea basket 3.

[0037] For example, the first engaging member 231 and the second engaging member 232 are cross-shaped, and correspondingly, the first slot 5111 and the second slot 5112 are also cross-shaped, which can improve the engagement stability and ensure the uniformity of force between the support 2 and the support 51. In other embodiments, the first engaging member 231 and the second engaging member 232 can also be arranged in an L-shape or a V-shape, etc., as long as the engagement connection between the support 2 and the support 51 can be achieved.

[0038] In some embodiments, the first limiting structure 23 includes a limiting groove, and the second limiting structure 511 includes a limiting protrusion. The limiting protrusion and the limiting groove are interlocked, and the cross-sections of both the limiting protrusion and the limiting groove are non-circular. The interlocking of the limiting protrusion and the limiting groove circumferentially limits the support 2 and the support base 51, preventing the support 2 from rotating relative to the support base 51 and ensuring that the support 2 can rotate stably.

[0039] For example, the cross-sectional shape of the limiting protrusion and the limiting groove can be a non-circular structure such as a rectangle or pentagon, as long as it can achieve a detachable connection between the support 2 and the support 51 and limit their relative position.

[0040] Optionally, the first drive member 5 has an output shaft, and the support base 51 is detachably fixed to the output shaft by fasteners, so that the support base 51 can rotate synchronously with the output shaft.

[0041] Optionally, see Figure 5The support 2 includes a support plate 21, and a stop structure 22 is provided along the circumferential direction of the support plate 21. The stop structure 22 surrounds a limiting area on the support plate 21, and the tea basket 3 is located within the limiting area. By setting the stop structure 22, the tea basket 3 can be limited, preventing the tea basket 3 from falling off the support 2 during rotation, thus improving the stability of the tea basket 3 on the support 2.

[0042] For example, the stop structure 22 can be a limiting flange provided on the support plate 21. For instance, the limiting flange can be integrally bent and formed on the outer edge of the support plate 21, which can simplify the processing technology of the support seat 2.

[0043] In other embodiments, the stop structure 22 may also include a plurality of stop protrusions spaced circumferentially on the support plate 21, as long as they can limit the tea basket 3, and are not limited to the specific forms of the stop structure 22 listed above.

[0044] Optionally, see Figure 1 and Figure 2 The chamber 1 is equipped with a doorway, and a closable door 6 is provided at the doorway. The tea basket 3 is placed on the support 2 inside the drying chamber 111 through the doorway. During the tea drying process, the door 6 is closed to ensure the airtightness of the drying chamber 111. When taking the tea basket 3 out, the door 6 can be opened to place the tea basket 3 on the support 2, or to remove the tea basket 3 from the support 2.

[0045] In this embodiment, refer to Figure 2 The doorway is located on the front side of the box 1, which is the side of the box 1 facing the user when the tea drying device is in normal use. The user can take the tea basket 3 from the front side, making the operation more convenient.

[0046] Optionally, the door 6 is hinged to the bottom side of the doorway. The door 6 opens and closes by flipping up and down. This design allows the door 6 to be opened without occupying space on the left, right, or top sides of the cabinet 1, facilitating better space layout and saving space for the tea drying device. Furthermore, the door 6 does not interfere with the tea basket 3 during user loading and unloading, making it more convenient. Additionally, the flip-up opening mechanism prevents hot air from directly hitting the user when the door is opened, improving the safety of the tea drying device.

[0047] Furthermore, a damper is provided at the hinge between the door 6 and the housing 1, so that the door 6 can open and close slowly, improving the stability and safety of the door 6 opening and closing.

[0048] Of course, in some other embodiments, a doorway may also be provided at the top of the housing 1 or other locations.

[0049] Optionally, see Figure 3 , Figure 10 and Figure 11 The housing 1 has a first mounting cavity 151 communicating with the drying chamber 111. The heating module 42 includes a heating coil. The drying fan 41 and the heating coil are spaced apart in the first mounting cavity 151 along the airflow direction. The first mounting cavity 151 provides mounting space for the drying fan 41 and the heating coil. When the drying fan 41 rotates, the airflow generated flows through the heating coil and is heated to form a hot airflow. The hot airflow enters the drying chamber 111 and comes into contact with the tea leaves in the tea basket 3, removing the moisture from the tea leaves and achieving tea drying.

[0050] Optionally, the tea drying device also includes a control module, which is communicatively connected to both the drying fan 41 and the heating module 42, and is able to control the opening and closing of the drying fan 41 and the heating module 42.

[0051] In some embodiments, the heating module 42 may also include a heating wire or a corrugated PTC, as long as it can heat the airflow generated by the drying fan 41.

[0052] Optionally, see Figure 3 , Figure 4 and Figure 11 A protective net 13 is provided between the first mounting cavity 151 and the drying chamber 111. The protective net 13 can separate the drying component 4 from the tea basket 3, prevent the user from contacting the drying component 4 when taking out or putting in the tea basket 3, prevent safety accidents, and improve the safety of the tea drying device.

[0053] See Figure 3 , Figure 10 and Figure 11 The housing 1 includes an inner shell 11 and an outer shell 12 covering the inner shell 11. The inner shell 11 defines a drying chamber 111. One side wall of the inner shell 11 has an opening 112, and an air duct shell 15 is provided at the opening 112. The air duct shell 15 defines a first mounting cavity 151, which communicates with the drying chamber 111 through the opening 112. Specifically, the air duct shell 15 is recessed in a direction away from the drying chamber 111 to form the first mounting cavity 151, so that the first mounting cavity 151 does not occupy the space inside the drying chamber 111, providing a sufficiently large accommodating space for the tea basket 3.

[0054] In this embodiment, the aforementioned opening 112 is provided on the rear side of the inner housing 11, and the outer peripheral edge of the air duct shell 15 is connected and fixed to the opening 112 of the inner housing 11. A protective net 13 is installed at the opening 112 of the inner housing 11 to isolate the first mounting cavity 151 from the drying chamber 111.

[0055] See Figure 3The heating coil is fixed in the first mounting cavity 151 by the bracket 16. In this embodiment, the bracket 16 is fixedly connected to the air duct shell 15. The bracket 16 has a hook, and the heating coil is hung on the hook.

[0056] Optionally, see Figure 10 and Figure 11 The housing 1 is provided with a second mounting cavity 14. The tea drying device also includes a cooling fan 7 and a second drive component 8. Both the cooling fan 7 and the second drive component 8 are located inside the second mounting cavity 14. The output end of the second drive component 8 is connected to the cooling fan 7 and / or the drying fan 41. The cooling fan 7 can exhaust the gas inside the second mounting cavity 14 to the external environment. When the cooling fan 7 is working, it causes thermal convection between the gas inside the second mounting cavity 14 and the external environment, thereby reducing the temperature inside the second mounting cavity 14 and dissipating heat for the second drive component 8, ensuring that the operating environment temperature of the second drive component 8 is suitable.

[0057] In this embodiment, the output end of the second driving component 8 is connected to both the drying fan 41 and the cooling fan 7, which reduces the number of driving components and simplifies the structural design of the tea drying device. The second driving component 8 drives the drying fan 41 and the cooling fan 7 to rotate simultaneously, so that while the drying fan 41 and the heating module 42 cooperate to provide hot airflow to the drying chamber 111, the cooling fan 7 dissipates heat from the second mounting cavity 14, ensuring the working stability of the second driving component 8.

[0058] Of course, in other embodiments, driving components can be configured for the drying fan 41 and the cooling fan 7 respectively to drive the drying fan 41 and the cooling fan 7 to rotate.

[0059] Optionally, see Figure 9 , Figure 10 and Figure 11 The tea drying device also includes an exhaust housing 9, which has a first inlet 91, a second inlet 92, and an exhaust port 93. The first inlet 91 is connected to the first mounting cavity 151, the second inlet 92 is connected to the second mounting cavity 14, and the exhaust port 93 is connected to the external environment. The drying fan 41 blows hot air into the drying chamber 111. The hot airflow comes into contact with the tea leaves in the tea basket 3, generating a gas containing moisture. This gas is then discharged to the external environment through the drying chamber 111, the first mounting cavity 151, the first inlet 91 of the exhaust housing 9, and the exhaust port 93. This allows the gas in the drying chamber 111 to continuously circulate to the external environment, improving the airflow circulation efficiency and thus improving the tea drying efficiency and uniformity.

[0060] At the same time, under the action of the cooling fan 7, the gas in the second mounting cavity 14 can be discharged to the external environment through the second inlet 92 and the exhaust port 93 of the exhaust housing 9, so that the hot gas in the second mounting cavity 14 can be discharged in time, reducing the temperature in the second mounting cavity 14 and ensuring good heat dissipation effect.

[0061] The exhaust housing 9 allows the humid gas in the drying chamber 111 and the hot gas in the second mounting chamber 14 to be discharged through the same exhaust port 93, thereby simplifying the structural design of the airflow circulation channel, making the structural layout inside the housing 1 more compact and reasonable, and helping to reduce the overall volume of the tea drying device.

[0062] See Figure 11 The air duct housing 15 is provided with a connecting port 152. The first inlet 91 of the exhaust housing 9 is connected to the first mounting cavity 151 through the connecting port 152. The outer housing 12 is provided with a mounting hole 1212. One end of the exhaust housing 9 with an exhaust port 93 is inserted into the mounting hole 1212 so that the exhaust port 93 is connected to the external environment.

[0063] Optionally, see Figure 10 and Figure 11 The enclosure 1 includes an inner shell 11 and an outer shell 12 covering the inner shell 11. A second mounting cavity 14 is defined between the outer shell 12 and the inner shell 11. The outer shell 12 has multiple vent holes 1211 in the area opposite to the cooling fan 7. When the cooling fan 7 is working, air from the external environment can enter the second mounting cavity 14 through the multiple vent holes 1211, while air in the second mounting cavity 14 is continuously discharged from the exhaust port 93 of the exhaust housing 9, allowing the air in the second mounting cavity 14 to circulate continuously, thereby ensuring the heat dissipation effect. By designing the enclosure 1 as a structure of inner shell 11 and outer shell 12, the cooling fan 7 and the second drive unit 8 can be completely hidden between the outer shell 12 and the inner shell 11, ensuring the aesthetic appearance of the enclosure 1.

[0064] In this embodiment, as Figure 9 river Figure 10 As shown, an installation port is provided on the rear side of the outer casing 12, and a rear cover 121 is detachably installed at the installation port. The rear cover 121, the rear side of the inner casing 11, and the air duct casing 15 form a second installation cavity 14. The rear cover 121 is provided with a plurality of ventilation holes 1211 as described above. The second drive component 8, the cooling fan 7, and other components in the second installation cavity 14 can be maintained through the installation port.

[0065] Furthermore, a limiting protrusion 1213 is provided on the back cover 121. When the tea drying device is placed, the limiting protrusion 1213 can maintain a certain distance between the back cover 121 and the external structure (such as the wall, cabinet surface, etc.) to ensure heat dissipation.

[0066] Optionally, see Figure 10 and Figure 11 A mounting bracket 10 is provided inside the second mounting cavity 14, and the second driving component 8 is fixed to the mounting bracket 10. The mounting bracket 10 provides a mounting base for the second driving component 8, enabling the second driving component 8 to stably drive the drying fan 41 and the cooling fan 7. In this embodiment, the mounting bracket 10 is fixed to the side of the air duct shell 15 facing away from the first mounting cavity 151, the cooling fan 7 is located between the mounting bracket 10 and the air duct shell 15, and the drying fan 41 and the cooling fan 7 are coaxially mounted on the output shaft of the second driving component 8.

[0067] See Figure 10 A fixing frame 101 is provided on the mounting bracket 10, which surrounds the communication port 152 of the air duct shell 15. One end of the exhaust shell 9, which has a first inlet 91 and a second inlet 92, is inserted into the fixing frame 101 to connect the first inlet 91 to the communication port 152 and the second inlet 92 to the second mounting cavity 14. Furthermore, the exhaust shell 9 and the fixing frame 101 are fixed together by a snap-fit ​​structure for easy assembly.

[0068] In this embodiment, as Figure 10 As shown, the fixing frame 101 and the mounting bracket 10 are integrally formed. When the mounting bracket 10 is fixed to the air duct shell 15, the fixing frame 101 is attached to the air duct shell 15 and surrounds the periphery of the communication opening 152. In other embodiments, the fixing frame 101 can also be set separately to fix the exhaust shell 9.

[0069] Optionally, see Figure 4 and Figure 10 A third mounting cavity 17 is formed between the inner top of the outer shell 12 and the outer top of the inner shell 11. The control module of the tea drying device is installed in the third mounting cavity 17. The control module includes a control circuit board 20. The third mounting cavity 17 is connected to the second mounting cavity 14. When the cooling fan 7 is working, it can simultaneously exhaust the gas in the third mounting cavity 17 to the external environment, thereby dissipating heat for the control circuit board 20 and ensuring the working stability of the control module.

[0070] Optionally, see Figure 4 and Figure 10 A fourth mounting cavity 18 is formed between the inner bottom of the outer shell 12 and the outer bottom of the inner shell 11. The fourth mounting cavity 18 is connected to the second mounting cavity 14. The first driving component 5 is located in the fourth mounting cavity 18. When the cooling fan 7 is working, it can simultaneously exhaust the gas in the fourth mounting cavity 18 to the external environment to dissipate heat from the first driving component 5 and ensure the working stability of the first driving component 5.

[0071] For example, both the first driving member 5 and the second driving member 8 can be a rotary motor or the like.

[0072] Example 2 This embodiment provides a control method for a tea drying device, used to control the tea drying device as described above. The tea drying device has multiple drying modes, and the control method includes the following steps: S1, Select the drying mode; S2. Control the drying component 4 to work according to the drying mode, and control the support seat 2 to drive the tea basket 3 to rotate.

[0073] The tea drying device control method provided in this embodiment allows the user to place damp tea leaves into a tea basket 3 and then place the tea basket 3 on a support 2 inside the drying chamber 111. The user then starts the tea drying device and selects a suitable drying mode, for example, selecting the appropriate drying mode based on the type of tea to be dried. After the drying mode is determined, the user controls the drying component 4 to operate and controls the support 2 to rotate the tea basket 3, causing the generated hot airflow to blow onto the rotating tea basket 3 inside the drying chamber 111 and enter the tea basket 3 through the vent 31, thus drying the tea leaves.

[0074] Because the tea basket 3 is always rotating during the drying process, hot air can enter the tea basket 3 from any ventilation hole 31 on the outer periphery of the tea basket 3. This allows tea leaves in any position in the tea basket 3 to fully contact the hot air, thereby improving the uniformity of heating of the tea leaves, enhancing the uniformity and efficiency of drying, and ensuring the drying effect and the taste of the tea leaves after brewing.

[0075] Optionally, such as Figure 4 and Figure 8 As shown, the tea drying device also includes a first driving component 5. A support base 51 is provided at the output end of the first driving component 5. The support base 2 is detachably connected to the support base 51. The first driving component 5 can drive the support base 51 to rotate the support base 2 and the tea basket 3. In step S2, after the drying mode is determined, the first driving component 5 controls the support base 51 to rotate the support base 2, thereby ensuring that the tea basket 3 remains in a rotating state during the drying process, guaranteeing that the tea leaves in the tea basket 3 are heated evenly.

[0076] For example, the rotational speed of the first driving component 5 (the rotational speed of the support 2) ranges from 2 rpm to 8 rpm. This speed is relatively low, so the tea basket 3 will not move or tip over arbitrarily during the rotation of the support 2. For example, the rotational speed of the first driving component 5 can be 3 rpm. In other embodiments, the rotational speed of the first driving component 5 can also be 2 rpm, 4 rpm, 5 rpm, 6 rpm, 7 rpm, 8 rpm, etc., but is not limited to the specific values ​​listed above.

[0077] In some embodiments, the rotation speed of the support 2 can be preset according to different drying modes. After the drying mode is determined, the rotation speed of the support 2 is controlled according to the set rotation speed.

[0078] In some embodiments, the wind speed of the drying fan 41 and the heating temperature of the heating module 42 can be preset according to different drying modes. When the drying component 4 is working, the drying fan 41 and the heating module 42 are controlled to operate according to the wind speed and heating temperature corresponding to the current drying mode, so that the heating temperature and wind speed match the type of tea to be dried, and ensure the brewing taste of the dried tea.

[0079] In some embodiments, the drying time can be preset according to different drying modes. When the drying time reaches the set drying time, the drying component 4 is controlled to stop working, and the support seat 2 is controlled to stop rotating, so as to ensure that the drying time is appropriate and avoid over-drying or under-drying of the tea.

[0080] Optionally, such as Figure 1 As shown, the cabinet 1 is equipped with a control panel 30, which includes a power switch 301, a mode selection button, and a temperature / time adjustment button. Users can select a suitable drying mode or adjust the drying temperature and time as needed.

[0081] Optionally, the tea drying device control method further includes the following steps: S3. In the current drying mode, control the support seat 2 to drive the tea basket 3 to rotate periodically and alternately along the first direction and the second direction; wherein, the first direction is opposite to the second direction.

[0082] That is, during the drying process, the support seat 2 is controlled to drive the tea basket 3 to rotate alternately in both directions, so that the hot airflow generated by the drying component 4 can convect more fully in the tea basket 3, thereby making the tea in the tea basket 3 heat more evenly, and further improving the drying uniformity and drying efficiency of the tea.

[0083] Optionally, the first driving component 5 can be a rotary motor capable of alternating forward and reverse rotation. By controlling the first driving component 5 to periodically alternate forward and reverse rotation, the tea basket 3 can be made to rotate alternately in the drying chamber 111.

[0084] For example, the support 2 can drive the tea basket 3 to change its rotation direction every 1 to 3 minutes. For example, the rotation direction can be changed every 1 minute, 2 minutes or 3 minutes, but is not limited to the specific values ​​listed above.

[0085] Optionally, the forward and reverse rotation cycle of the first drive unit 5 can be set according to different drying modes. When the user selects the corresponding drying mode, the first drive unit 5 is controlled to run according to the set forward and reverse rotation cycle.
