[0037] Example 1

[0038] Please see Figures 1 to 6 The present invention provides a cooking appliance 100, which includes a pot body 10, a heating plate 30, a cooling fan 40, and a control module 50.

[0039] The pot body 10 includes an installation cavity 13; an air guide 20 is disposed in the installation cavity 13, the air guide 20 surrounds and forms an installation space 21, and the two free ends of the air guide 20 surround and form an air outlet 22; a heating plate 30 is disposed on the top wall of the installation cavity 13; a cooling fan 40 is disposed below the heating plate 30 and within the installation space 21; and a control module 50 is disposed below the heating plate 30 and at the air outlet 22.

[0040] The cooking appliance 100 described above, by setting an air guide 20 in the mounting cavity 13, forms an installation space 21 for the cooling fan 40. The air guide 20 is provided with an air outlet 22, and the control module 50 is located at the air outlet 22. When the cooling fan 40 disturbs the airflow to dissipate heat from the heating plate 30 located above it, some of the airflow can flow to the air outlet 22 under the obstruction of the air guide 20. When it flows out of the air outlet 22, it can also flow through the control module 50, and simultaneously dissipate heat from the control module 50. Thus, the service life of the control module 50 is improved, and the utilization rate of the airflow is also improved.

[0041] In this embodiment, the cooking appliance 100 can be an air fryer, steamer, rice cooker, or other appliance used for cooking food. Specifically, this embodiment will be described using an air fryer as an example. The heating plate 30 is configured as an IH heating plate 30, which heats the food inside the pot 10 by generating an inductive magnetic field, offering the advantage of high heat conversion efficiency.

[0042] The pot body 10 includes an inner pot 11 and an outer pot 12 surrounding the inner pot 11, with an installation cavity 13 formed between the inner pot 11 and the outer pot 12. When installing the inner pot 11 and the outer pot 12, an overlapping platform can be provided at the opening of the outer pot 12, and an overlapping edge can be provided at the edge of the inner pot 11. By overlapping the overlapping edge onto the overlapping platform, the inner pot 11 is positioned and installed. Furthermore, the bottom of the inner pot 11 and the bottom of the outer pot 12 have a certain gap, thereby forming the installation cavity 13 between them.

[0043] In addition, the air fryer also includes a lid 60, which is used to open or close the opening of the pot body 10. Understandably, the lid 60 may also contain a heating coil of the heating element type, thereby heating the upper surface of the food. This, together with the heating plate 30 at the bottom of the pot body 10, heats both the upper and lower sides of the food, improving cooking efficiency. Simultaneously, the rapid heating of both the upper and lower sides of the food also enhances its texture. Furthermore, for easy handling, the lid 60 in this embodiment opens or closes the opening of the pot body 10 by flipping.

[0044] Understandably, please refer to Figures 1 to 3 In this embodiment, the bottom of the inner pot 11 is used to install the heating plate 30. The air fryer in this embodiment also includes an inner liner 200, which is used to hold food. It is detachably set in the inner pot 11, and the inner liner 200 is a magnetic pot body so that when the IH heating plate 30 is powered on, a magnetic field is generated to heat the food in the inner liner 200. After cooking is completed, the food can be taken out through the inner liner 200, which is convenient for the user.

[0045] It should be noted that by setting the heating plate 30 to generate a magnetic field to heat the food, after the inner pot 200 is placed inside the pot body 10, the air fryer 100 of this embodiment can also be used as a steamer. When it is necessary to steam or cook food, water can be placed in the inner pot 200, and a support frame can be attached to the inner pot 200 to support the food. When the heating plate 30 is powered on, the food can be steamed or cooked, thereby improving the practicality of the air fryer 100 of this application and providing multiple usage methods. At the same time, by directly filling the inner pot 200 with water, it is possible to avoid installing an additional water-holding device in the pot body 10, which can reduce the overall molding cost of the machine.

[0046] Please see Figures 4 to 6 The structure of the control module 50 in this embodiment includes a circuit board 51 and heat dissipation fins 52 disposed on the circuit board 51, as well as other electronic components, and is disposed at the air outlet 22. Thus, the heat dissipation fins 52 are just disposed at the air outlet 22. When the cooling fan 40 drives the airflow through the air outlet 22, it just carries away the heat of the heat dissipation fins 52, thereby reducing the temperature of the IGBT and rectifier bridge and ensuring the service life of the control module 50.

[0047] Understandably, the exhaust direction of the cooling fan 40 and the extension direction of the heat dissipation fins 52 are set at an angle. For example, the angle can be set between 0° and 90°. For instance, when the angle between the exhaust direction and the extension direction of the heat dissipation fins 52 is 0°, the airflow carries away the heat from the surface of the heat dissipation fins 52 along the extension direction of the heat dissipation fins 52. When the angle between the exhaust direction and the extension direction of the heat dissipation fins 52 is 90°, the airflow hits the heat dissipation fins 52, changes its flow direction by the heat dissipation fins 52, and flows along the surface of the heat dissipation fins 52, thereby carrying away the surface heat of the heat dissipation fins 52.

[0048] Furthermore, to improve the heat dissipation effect, the control module 50 of this embodiment includes multiple heat dissipation fins 52, which are arranged in parallel and spaced apart. In order to achieve simultaneous heat dissipation of multiple heat dissipation fins 52, when the cooling fan 40 drives the airflow outward, the extension direction of the heat dissipation fins 52 is located in the outward direction of the airflow. That is, the cooling fan 40 can drive the airflow to the gap between adjacent heat dissipation fins 52, so as to remove the heat from the surface of each heat dissipation fin 52 and ensure the heat dissipation effect of each heat dissipation fin 52.

[0049] Please see Figure 6In this embodiment, when the air guide 20 is installed, the air guide 20 includes an enclosure 23, a first air guide 24 and a second air guide 25 disposed at both ends of the enclosure 23. The enclosure 23 is provided with an installation space 21. An air outlet 22 is formed between the first air guide 24 and the second air guide 25. The first air guide 24 and the second air guide 25 are disposed on both sides of the heat dissipation fins 52. In this way, when the cooling fan 40 drives the airflow out, it is blocked by the first air guide 24 or the second air guide 25, which can gather the airflow and make it flow in the direction of the heat dissipation fins 52, thereby realizing the heat dissipation of the heat dissipation fins 52.

[0050] Specifically, the first air guide 24 extends along the tangential direction to the corresponding end of the enclosure 23 and can be located to the side of the central axis of the heating plate 30, thereby avoiding the placement of the heating plate 30. The second air guide 25 is arranged at an acute angle to the tangential direction of its corresponding end and is arranged in a direction away from the first air guide 24, thereby avoiding the end of the control module 50. Specifically, it avoids the placement of the heat dissipation fins 52, so that the first air guide 24 and the second air guide 25 can surround both sides of the heat dissipation fins 52.

[0051] Specifically, when the cooling fan 40 drives the airflow out, that is, when it rotates counterclockwise, the airflow, blocked by the first air guide 24, flows towards the cooling fins 52 in a direction roughly parallel to the extension direction of the cooling fins 52, thereby achieving the heat dissipation effect on the cooling fins 52.

[0052] Furthermore, when setting the cooling fan 40, the projection of the rotation center of the cooling fan 40 onto the reference plane in the vertical direction is located outside the projection surface of the heating plate 30 onto the reference plane in the vertical direction. The projection surface of the cooling fan 40 on the reference plane and the projection surface of the heating plate 30 on the reference plane partially overlap. The area of ​​the overlapping part of the projection surface of the heating plate 30 and the projection surface of the cooling fan 40 is 1 / 5 to 3 / 10 of the area of ​​the projection surface of the heating plate 30. This ensures that the overlapping part of the heating plate 30 and the cooling fan 40 is not too small, which would weaken the cooling effect of the airflow driven by the cooling fan 40 on the heating plate 30. It also avoids the overlapping part being too large. When the overlapping part is too large, the outer edge of the cooling fan 40 may touch the plug, and the cooling fan 40 may interfere with the plug, affecting the rotation of the cooling fan 40.

[0053] In some embodiments, the area of ​​the overlapping portion of the projection surface of the heating plate 30 and the projection surface of the cooling fan 40 is 1 / 5, 1 / 4 or 3 / 10 of the area of ​​the projection surface of the heating plate 30, and is not limited here.

[0054] Further, please refer to Figure 6The second air guide 25 is attached to the side wall of the outer pot 12, and the first air guide 24 is set close to the circuit board 51, so that the airflow driven by the cooling fan 40 is gathered and flowed out through the flow channel formed between the first air guide 24 and the second air guide 25 as much as possible; furthermore, connecting the second air guide 25 to the inner wall of the outer shell can not only improve the air guiding effect, but also increase the structural strength of the outer pot 12.

[0055] Please see Figures 1 to 5 In one embodiment of this utility model, in order to detect the temperature of food in real time, the cooking appliance 100 also includes a temperature probe 70. The temperature probe 70 is inserted into the bottom of the inner pot 11 and is arranged coaxially with the heating plate 30. Since the central axis of the heating plate 30 is located in the air outlet direction of the air outlet 22, by arranging the temperature probe 70 and the heating plate 30 coaxially, it is convenient to set up the cooling fan 40 and the control module 50, avoiding occupying the setting space of the cooling fan 40 and the control module 50.

[0056] Specifically, in this embodiment, the temperature probe 70 also includes a mounting sleeve 80 and an elastic element 90. The inner wall of the outer pot 12 is provided with a mounting post 121. The temperature probe 70 is slidably mounted on the mounting post 121. The elastic element 90 is sleeved on the outside of the mounting post 121, and its two ends abut against the mounting sleeve 80 and the inner bottom wall of the outer pot 12, respectively. The heating plate 30 is connected to the outer bottom wall of the inner pot 11, which can realize the installation limit of the temperature probe 70. When the inner pot is placed in the inner pot 11, it touches the temperature probe 70 and compresses the elastic element 90. The elastic element 90 applies an upward elastic force to the temperature probe 70 so that the temperature probe 70 can always contact the outer bottom wall of the inner pot 200, thereby monitoring the temperature in real time.

[0057] Further, please refer to Figure 3 In order to guide the movement of the elastic member 90, the mounting sleeve 80 includes a support plate 81 and a sleeve 82. The sleeve 82 is located on the side of the support plate 81 facing the elastic member 90 and is located circumferentially on the edge of the support plate 81. In this way, the sleeve 82 can guide the movement of the elastic member 90 and limit the movement of the elastic member 90.

[0058] Specifically, in order to achieve a compact structure for the entire cooking appliance 100, the control module 50 is provided with a clearance notch 53, and the temperature probe 70 is located in the clearance notch 53. Specifically, the circuit board 51 is provided with a clearance notch 53, so that the installation of the temperature probe 70 can be avoided by setting the clearance notch 53, thereby achieving a compact structure and miniaturizing the entire cooking appliance 100.

[0059] During installation, the heating plate 30 is provided with mounting ears 31. Correspondingly, a connecting post can be provided at the bottom of the inner pot 11. The connecting post and the mounting ears 31 are connected by bolts to realize the installation of the heating plate 30. After the heating plate 30 is installed, since the mounting sleeve 80 is fitted on the temperature probe 70, it cannot slide off relative to the heating plate 30, thus limiting the installation of the temperature probe 70 and preventing the temperature probe 70 from falling off relative to the inner pot 11 and the outer pot 12.

[0060] Specifically, the heat dissipation method of the cooking appliance 100 in this embodiment is as follows: the outer pot 12 is provided with an air inlet 14 and an air outlet 15. The air inlet 14 is located below the cooling fan 40. Driven by the cooling fan 40, the airflow flows upward to the heating plate 30 to dissipate heat from the heating plate 30. When the airflow touches the bottom of the inner pot 11, the airflow changes direction and flows out from the air outlet 15 provided on the outer periphery of the outer pot 12. At the same time, under the blocking effect of the air guide rib 20, part of the airflow driven by the cooling fan 40 is guided to the control module 50, thereby achieving heat dissipation of the control module 50, and finally also flows out through the air outlet 15.

[0061] The aforementioned cooking appliance 100, by setting a heating plate 30 on the pot body 10, can work together with the heating coil on the lid 60 to heat food. Both the top and bottom sides of the food can quickly receive heat, which not only improves cooking efficiency but also enhances the taste of the food. Furthermore, by setting the heating plate 30 as an IH heating plate, water can be directly placed in the inner pot 200 made of magnetic material, thereby steaming or boiling the food placed in the inner pot 200. This avoids the need for a separate steam generator in the whole machine, reducing the assembly cost and improving the practicality of the whole machine. By setting the lid 60 to open or close the pot body 10 by flipping it, the inner pot 200 can be taken out and put in the pot body 10 by moving up and down, avoiding the large frictional force between the inner pot and the temperature probe 50 that would cause damage when taking it out in a drawer-style manner.

[0062] The above provides a detailed description of a fresh air module and a fresh air conditioner disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the fresh air module and fresh air conditioner of this utility model and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
