Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a pot body and cooking device. Background Technology

[0002] Existing cooking appliances primarily use heating plates and electromagnetic induction heating (IH). Both methods involve heating the inner metal pot first through heat conduction, then transferring the heat to the water inside the pot before cooking the food. This heat conduction method generally suffers from uneven heating of the food and low cooking efficiency. Therefore, the microwave rice cooker was invented, utilizing the principle of microwave penetration heating to directly heat the water, achieving rapid and even temperature rise.

[0003] The magnetron in a microwave rice cooker generates a lot of heat during operation, requiring a good heat dissipation system. To solve the problem of magnetron overheating, related technologies have designed an independent magnetron heat dissipation structure, using an axial fan to directly dissipate heat from the magnetron. However, this leads to increased heat at the air outlet, resulting in high air temperature and a risk of burns. Utility Model Content

[0029] Existing cooking appliances primarily use heating plates and electromagnetic induction heating (IH). Both methods involve heating the inner metal pot first through heat conduction, then transferring the heat to the water inside the pot before cooking the food. This heat conduction method generally suffers from uneven heating of the food and low cooking efficiency. Therefore, the microwave rice cooker was invented, utilizing the principle of microwave penetration heating to directly heat the water, achieving rapid and even temperature rise.

[0030] The magnetron in a microwave rice cooker generates a lot of heat during operation, requiring a good heat dissipation system. To solve the problem of magnetron overheating, related technologies have designed an independent magnetron heat dissipation structure, using an axial fan to directly dissipate heat from the magnetron. However, this leads to increased heat at the air outlet, resulting in high air temperature and a risk of burns.

[0031] In view of this, and in response to the problem that the high exhaust temperature of the independent magnetron heat dissipation structure can easily cause burns, this utility model proposes a pot body 10 and a cooking device 100, which aims to improve the problem of high exhaust temperature of the independent magnetron heat dissipation structure.

[0032] The specific structure of the pot body 10 and cooking device 100 of this utility model will be described below:

[0033] Please refer to Figures 1 to 5 This utility model proposes a pot body 10, which includes: a base 11, the base 11 having a cooking cavity 110 with a top opening, the base 11 also having a mounting cavity 111 and an air inlet 1131 and an air outlet 1132 communicating with the mounting cavity 111, the mounting cavity 111 being located below the cooking cavity 110, and the mounting cavity 111 having a partition (not shown in the figure) dividing the space within the mounting cavity 111 into a first air duct 1133 and a second air duct 1134. The mounting cavity 111 is also provided with a mixing air duct 1136. One end of the first air duct 1133 and the second air duct 1134 are connected to the air inlet 1131, and the other end is connected to the mixing air duct 1136. The end of the mixing air duct 1136 away from the first air duct 1133 is connected to the air outlet 1132. A frequency converter board 121 is disposed in the first air duct 1133. A microwave generating module 13 is disposed in the second air duct 1134.

[0034] Specifically, the cooker body 10 includes a base 11, a frequency converter 121, and a microwave generating module 13. The base 11 is used to provide a cooking cavity 110 and a mounting cavity 111. The cooking cavity 110 is used to cook food, the mounting cavity 111 is used to install and protect internal components, the frequency converter 121 is used to manage and convert electrical energy to meet the needs of other components, and the microwave generating module 13 (i.e., magnetron) is used to generate microwaves.

[0035] Since both the inverter board 121 and the microwave generator module 13 are located within the mounting cavity 111 of the base 11, a partition is provided within the mounting cavity 111 to divide the space into a first air duct 1133 and a second air duct 1134. The first air duct 1133 provides heat dissipation for the inverter board 121, and the second air duct 1134 provides heat dissipation for the microwave generator module 13. A mixing air duct 1136 is also provided within the mounting cavity 111. The mixing air duct 1136 is connected to the outlets of the first air duct 1133 and the second air duct 1134, allowing the air from the first air duct 1133 and the second air duct 1134 to be mixed and then discharged from the exhaust port 1132.

[0036] The partition can be a component installed inside the mounting cavity 111, which can be used to simply divide the mounting cavity 111 to form the first air duct 1133 and the second air duct 1134; or a partition plate or other structure can be set separately to divide the mounting cavity 111.

[0037] like Figure 3 The dashed arrows indicate the flow directions of the first air duct 1133 and the second air duct 1134. The first air duct 1133 and the second air duct 1134 share an air inlet 1131. Since the temperature of the microwave generating module 13 is high and the temperature of the inverter board 121 is low, the heat of the inverter board 121 is directly discharged to the mixing air duct 1136 through the first air duct 1133, and the microwave generating module 13 is cooled through the second air duct 1134. The air passing through the microwave generating module 13 in the second air duct 1134 will flow towards the mixing air duct 1136. At this time, the air passing through the microwave generating module 13 and the air passing through the inverter board 121 converge in the mixing air duct 1136, mix, and then are discharged from the exhaust port 1132. The air generated by the microwave generator module 13 is hot air, and the air generated by the frequency converter board 121 is cold air. After the hot air and cold air are mixed in the mixing duct 1136, the temperature decreases. At this time, it is discharged from the exhaust port 1132. The heat is reduced and the exhaust temperature is low, which reduces the occurrence of burn accidents.

[0038] It should be understood that in related technologies, an independent heat dissipation structure is designed for both the magnetron and the frequency converter board 121, resulting in two separate heat dissipation systems within the device. This layout requires a large space and is not conducive to product miniaturization. However, in this utility model, through a reasonable layout, both the microwave generating module 13 and the frequency converter board 121 are housed within the mounting cavity 111. The first air duct 1133, the second air duct 1134, and the mixed air duct 1136 are rationally designed, which not only achieves heat dissipation and reduces the outlet air temperature but also enables the miniaturization of the product.

[0039] This utility model's technical solution involves opening an air inlet 1131 and an air outlet 1132 on the base 11, and forming a first air duct 1133 and a second air duct 1134 within the mounting cavity 111 by setting a separator. Simultaneously, a mixing air duct 1136 is provided within the mounting cavity 111. The frequency converter board 121 is located in the first air duct 1133 and dissipates heat through it, while the microwave generator module 13 is located in the second air duct 1134 and dissipates heat through it. The air from the first air duct and the second air duct 1134 enter the mixing air duct 1136 and mix. Since the air passing through the microwave generating module 13 is hot air and the air passing through the frequency converter 121 is low-temperature air, the hot air passing through the microwave generating module 13 and the low-temperature air passing through the frequency converter 121 mix in the mixing air duct 1136, which can reduce the heat and discharge it from the exhaust port 1132. This can reduce the outlet air temperature of the exhaust port 1132, reduce the occurrence of burn accidents, and at the same time realize the miniaturization design of the product.

[0040] In an embodiment of this utility model, the air inlet 1131 and the air outlet 1132 are arranged opposite to each other, the first air duct 1133 is straight, and the two ends of the first air duct 1133 are respectively facing the air inlet 1131 and the air outlet 1132.

[0041] Specifically, the exact locations of the air inlet 1131 and the air outlet 1132 can be set according to actual needs; they can be staggered or correspondingly positioned. In one embodiment, as shown... Figure 3 The air inlet 1131 and the air outlet 1132 are arranged opposite each other, that is, the air inlet 1131 and the air outlet 1132 are directly opposite each other. At the same time, the first air duct 1133 is straight, with its two ends directly opposite the air inlet 1131 and the air outlet 1132, respectively. Therefore, it can reduce the bends and turns in the air flow path, reduce the air flow resistance, and allow the air to pass through the first air duct 1133 more smoothly, which helps to quickly remove the heat from the inverter board 121 and improve the heat dissipation efficiency of the inverter board 121.

[0042] In an embodiment of this utility model, the second air duct 1134 includes a heat dissipation section 1134a and a connecting section 1134b. The heat dissipation section 1134a connects to the air inlet 1131, and the connecting section 1134b connects the heat dissipation section 1134a and the air outlet 1132. The connecting section 1134b is bent and connected to the heat dissipation section 1134a. The microwave generating module 13 is disposed on the heat dissipation section 1134a. The heat dissipation section 1134a is straight, and the straight extension direction of the heat dissipation section 1134a is consistent with the straight extension direction of the first air duct 1133.

[0043] Specifically, such as Figure 3 The heat dissipation section 1134a and the connecting section 1134b are bent and connected. The second air duct 1134 is bent. Air enters from the air inlet 1131, passes through the heat dissipation section 1134a to dissipate heat from the microwave generator module 13, and then is guided to the mixing air duct 1136 through the connecting section 1134b so that the air passing through the microwave generator module 13 can be mixed with the air passing through the frequency converter board 121 and then discharged from the exhaust port 1132.

[0044] The straight extension direction of the heat dissipation section 1134a is consistent with the straight extension direction of the first air duct 1133, and the air can pass through the microwave generating module 13 more smoothly, which helps to quickly remove the heat of the microwave generating module 13.

[0045] This design can better meet the heat dissipation requirements of the microwave generating module 13. In the bent second air duct 1134, the heat dissipation section 1134a can quickly remove the heat from the microwave generating module 13, and the connecting section 1134b increases the contact area between the airflow and the microwave generating module 13, thus improving the overall heat dissipation effect. After the hot air from the second air duct 1134 and the low-temperature air from the first air duct 1133 are mixed in the mixing air duct 1136, the temperature of the finally discharged airflow can be more uniform, reducing the outlet air temperature.

[0046] In an embodiment of this utility model, the pot body 10 further includes a flow guiding structure 14, which is disposed inside the base 11. The flow guiding structure 14 is located at the connection between the heat dissipation section 1134a and the connecting section 1134b of the second air duct 1134, and is used to guide the airflow in the heat dissipation section 1134a to the connecting section 1134b.

[0047] It is worth noting that a flow guiding structure 14 is also provided at the connection between the heat dissipation section 1134a and the connecting section 1134b. The flow guiding structure 14 can be a structure on the base 11, such as using the side wall of the base 11 to form a flow guiding effect, or it can be a separate flow guiding structure 14. The specific method can be selected according to actual needs.

[0048] The airflow guiding structure 14 can guide the airflow through the heat dissipation section 1134a to the connecting section 1134b, ensuring that the airflow flows in the expected direction, which helps to improve the airflow efficiency, allowing the airflow to pass through the second air duct 1134 more smoothly, improving airflow efficiency and improving the heat dissipation effect on the microwave generating module 13.

[0049] In an embodiment of this utility model, the airflow guiding structure 14 includes an airflow guiding plate 141, which is arranged in an arc-shaped bend. The airflow guiding plate 141 is disposed inside the base 11 and close to the end of the microwave generating module 13 that is away from the air inlet 1131.

[0050] In detail, such as Figure 3 The airflow guiding structure 14 is configured as an arc-shaped bend guide plate 141. When heat dissipation is performed, the guide plate 141 changes the direction of the hot air passing through the microwave generating module 13, guiding the airflow to smoothly turn along the predetermined direction. The airflow in the second air duct 1134 can flow more smoothly when turning, which helps to maintain the airflow speed. This allows the hot air in the second air duct 1134 to better mix with the low-temperature air in the first air duct 1133 and be cooled before being discharged from the exhaust port 1132, improving heat dissipation efficiency and further reducing the temperature of the discharged hot air.

[0051] In an embodiment of this utility model, the air inlet 1131 includes a first air outlet 1131a that connects to the first air duct 1133 and a second air outlet 1131b that connects to the second air duct 1134; the cooker body 10 also includes two cooling fans 15, one of which is located at the first air outlet 1131a and the other is located at the second air outlet 1131b.

[0052] Specifically, such as Figure 3 Two cooling fans 15 are designed to correspond to the first air duct 1133 and the second air duct 1134 respectively. The air outlets of the cooling fans 15 deliver cold air to the microwave generating module 13 and the frequency converter board 121 respectively, which can increase the airflow speed of the first air duct 1133 and the second air duct 1134, ensuring that the microwave heating module and the frequency converter board 121 can obtain sufficient airflow for heat dissipation. The simultaneous operation of the two cooling fans 15 can increase the total airflow, thereby improving the overall heat dissipation capacity and heat dissipation efficiency.

[0053] The cooling fan 15 can be installed on the outside of the first air vent 1131a and the second air vent 1131b, or on the inside of the first air vent 1131a and the second air vent 1131b. The specific installation position can be selected according to actual needs.

[0054] Furthermore, the air inlet 1131 also includes two side air inlets 1131c. A side air inlet 1131c is provided on the side of the first air inlet 1131a away from the second air inlet 1131b, and another side air inlet 1131c is provided on the side of the second air inlet 1131b away from the first air inlet 1131a. This design can increase the total air intake area, allowing more air to enter the interior of the base 11. The airflow can enter the base 11 from different positions, and more airflow can cover a wider area, making the internal airflow more uniform and improving the overall ventilation effect, thereby improving the air intake efficiency and heat dissipation effect.

[0055] In addition, the cook body 10 also includes a fixed bracket 16, which is located inside the base 11. The two cooling fans 15 and the frequency converter 121 are all mounted on the fixed bracket 16, and the cooling fans 15 and the frequency converter 121 are supported and fixed by the fixed bracket 16.

[0056] In an embodiment of this utility model, the air inlet 1131 includes a plurality of circular through holes, the diameter of which ranges from Φ2mm to Φ12mm; and / or, the total area S1 of the air inlet 1131 and the projected area S2 of the fan blades of the cooling fan 15 satisfy 0.4≤S1 / S2≤2.

[0057] Specifically, the air inlet 1131 is designed as a circular through-hole with smooth edges to reduce airflow resistance at the inlet. This facilitates continuous and stable airflow, improving efficiency, and the circular through-hole is also easy to manufacture. Simultaneously, the circular through-hole serves to provide microwave shielding while meeting heat dissipation requirements. In particular, limiting the diameter of the circular through-hole to Φ2mm~Φ12mm ensures no microwave leakage. Since the frequency converter board 121 and microwave generator module 13 within the mounting cavity 111 are susceptible to microwave leakage, the air inlet 1131 is designed with multiple circular through-holes, and the diameter is limited to prevent microwave shielding.

[0058] Furthermore, air inlets 1131 with different diameters can adapt to different heat dissipation requirements. Larger diameters can provide greater airflow and higher heat dissipation capacity, while smaller diameters can reduce airflow speed and control airflow. In this embodiment, the diameter range of the air inlets 1131 is set to Φ2mm~Φ12mm, which can more precisely control the airflow. Multiple small-diameter air inlets 1131 can disperse the airflow, making the airflow distribution more uniform and improving the overall performance of the heat dissipation system.

[0059] Furthermore, to ensure effective air intake, the total area S1 of the air inlet 1131 and the projected area S2 of the fan blades of the cooling fan 15 satisfy: 0.4 ≤ S1 / S2 ≤ 2, resulting in a large distribution and coverage area. The total area S1 of the air inlet 1131 refers to the total air intake area. This design allows for a more even distribution of airflow within the base 11, better covering the areas requiring heat dissipation. By increasing the total air intake area, sufficient cool air can be introduced for heat dissipation, thereby improving the overall system's heat dissipation capacity.

[0060] In an embodiment of this utility model, the base 11 includes a housing 112 and a shielding cover 113. The shielding cover 113 is disposed inside the housing 112, and the space enclosed inside the shielding cover 113 is the mounting cavity 111. The frequency converter board 121 and the microwave generating module 13 are both disposed inside the shielding cover 113. The shielding cover 113 is provided with an air inlet 1131 and an air outlet 1132. The housing 112 is provided with an opening 1121 that connects the air inlet 1131 and the air outlet 1132.

[0061] In detail, such as Figure 2 The outer casing 112 has an opening 1121 for air to enter or exit. The shield 113 effectively blocks microwaves, while the design of the air inlet 1131 and exhaust vent 1132 allows for airflow. The space enclosed within the shield 113 is the mounting cavity 111, where the microwave generating module 13 and other devices that may generate microwaves are placed, thus improving safety. By designing the air inlet 1131 and exhaust vent 1132 on the shield 113 and opening the opening 1121 on the outer casing 112, a good airflow channel can be formed. Air can enter from the opening 1121, flow through the first air duct 1133, the second air duct 1134, and the mixing air duct, cooling the frequency converter board 121 and the microwave generating module 13, and mixing the hot air passing through the microwave generating module 13 with the low-temperature air passing through the frequency converter board 121, finally exiting from the exhaust vent 1132, ensuring effective heat dissipation of the internal components.

[0062] It should be noted that the shielding cover 113 can be a device made of a material capable of shielding microwaves, such as a metal cover. The air inlet on the shielding cover 113 is designed to include multiple circular through holes, the diameter of which ranges from Φ2mm to Φ12mm, so as to meet the heat dissipation requirements while also providing shielding functionality.

[0063] In addition, in one embodiment, the cooling fan 15 is disposed inside the shield 113 and near the air inlet 1131 to ensure the air intake effect.

[0064] In an embodiment of this utility model, the outer shell 112 and the shield 113 are spaced apart and form an auxiliary air duct 1122 communicating with the air inlet 1131 or the air outlet 1132; the passage 1121 includes a first passage 1121a and a second passage 1121b, the first passage 1121a is disposed directly opposite the air inlet 1131, and the second passage 1121b is disposed directly opposite the air outlet 1132.

[0065] In some embodiments, the housing 112 is further provided with a heat dissipation vent 1123, which is in communication with the mounting cavity 111.

[0066] In some embodiments, the cooker body 10 further includes a circuit board 122, which is disposed between the outer shell 112 and the shield 113, and the circuit board 122 is located outside the first air duct 1133. The portion of the shield 113 used to form the first air duct 1133 is provided with an auxiliary air vent 1135, and the air blown from the auxiliary air vent 1135 blows toward the circuit board 122.

[0067] It is worth noting that the design of the vent 1121 allows for smoother airflow. The first vent 1121a is directly opposite the air inlet 1131 of the shield 113, and the second vent 1121b is directly opposite the air outlet 1132 of the shield 113. Since the outer shell 112 and the shield 113 are spaced apart, an auxiliary air duct 1122 is formed between them. The auxiliary air duct 1122 can be located at the air inlet 1131 and connected to it; it can also be located at the air outlet 1132 and connected to it; or it can be located at both the air inlet 1131 and the air outlet 1132; or it can be a circumferentially connected auxiliary air duct 1122 formed between the outer shell 112 and the shield 113, which is connected to both the air inlet 1131 and the air outlet 1132. The auxiliary air duct 1122 can optimize the airflow path, allowing air to be distributed more evenly in the area that needs cooling.

[0068] The design of the auxiliary air duct 1122 can increase the contact area between the airflow and the components, thereby improving heat exchange efficiency. The space between the outer casing 112 and the shield 113 can be effectively utilized as part of the auxiliary air duct 1122. This makes full use of the limited space and achieves a more efficient heat dissipation design.

[0069] Furthermore, additional heat dissipation vents 1123 are provided on the outer casing 112, such as... Figure 2The first passage 1121a and the second passage 1121b are located on two opposite side walls of the outer casing 112, while the heat dissipation vent 1123 is located on the bottom wall of the outer casing 112. The additional heat dissipation vent 1123 at the bottom can increase the heat dissipation area, enhance the ventilation effect, provide more heat dissipation paths for hot air to be discharged, thereby improving the overall heat dissipation efficiency.

[0070] Furthermore, such as Figure 3 and Figure 5 The circuit board 122 is positioned between the shielding cover 113 and the outer shell 112. Part of the airflow is introduced into the space between the shielding cover 113 and the outer shell 112 through the auxiliary air vent 1135 to dissipate heat from the circuit board 122. The airflow then flows from the space between the shielding cover 113 and the outer shell 112 to the exhaust vent 1132 and is discharged from the exhaust vent 1132. This design provides more heat dissipation paths, can better manage the internal temperature, improve the overall efficiency of the heat dissipation system, and increase the utilization rate of the cooling fan 15. At the same time, there is no need to add a separate heat dissipation structure to the circuit board 122, further reducing the overall size of the product.

[0071] This utility model also provides a cooking device 100, including a cover 20 and a pot body 10 as described above. The cover 20 is connected to the pot body 10 and is closable and covers the top opening of the cooking cavity 100.

[0072] Specifically, such as Figure 1 The lid 20 is closable and is located at the top opening of the cooking cavity 100. The lid 20 can be opened by a button.
