[0053] Most existing modular cooking appliances are three-dimensional combinations. When working, each cooking module generates a lot of heat, which causes heat to accumulate in the enclosed space, resulting in excessively high internal temperatures and increasing the risk of overheating during use.

[0054] The main objective of this invention is to provide a cooking appliance that aims to at least solve the problem of heat buildup in modular cooking appliances in the related art.

[0055] The system comprises an electrical component 2, a second electrical component 3, an electrical control device 4, and a first fan assembly 5. The main body 1 has a heating chamber 11 and an opening that communicates with and can be opened and closed. A heating zone is located above the heating chamber 11 at the upper end of the main body 1. The heating zone and the heating chamber 11 are at least partially opposite each other in the vertical direction. An upper cavity 12 is formed within the main body 1, located between the heating zone and the heating chamber 11. A mounting cavity 13 is formed on one side of the heating chamber 11 in the horizontal direction within the main body 1. The main body 1 is provided with an air inlet 1a communicating with the mounting cavity 13 and an air outlet 1b communicating with the upper cavity 12. The first electrical component 2 includes a first heating device 21. 21 is disposed in the main body 1 for heating the food in the heating chamber 11; the second electrical component 3 is disposed in the upper cavity 12, and the second electrical component includes a second heating device 31, which is disposed in the upper cavity 12 for heating the pot placed in the heating zone; the electrical control device 4 is disposed in the mounting cavity 13, and the electrical control device 4 is electrically connected to the first electrical component 2 and the second electrical component 3; the first fan assembly 5 is disposed at the junction of the upper cavity 12 and the mounting cavity 13, and the first fan assembly 5 has a first air outlet and a first air inlet, the first air outlet is connected to the upper cavity 12 and is oriented toward the second electrical component 3, and the first air inlet is connected to the mounting cavity 13.

[0056] In the technical solution of the present invention, the first heating device 21 of the first electrical component 2 is disposed in the main body 1 to heat the food in the heating chamber 11, and the second heating device 31 of the second electrical component 3 is disposed in the upper cavity 12 to heat the pot placed in the heating zone. The electronic control device 4 used to control the first electrical component 2 and the second electrical component 3 is separately disposed in the mounting cavity 13, which can reduce the impact of the heat of the first electrical component 2 and the second electrical component 3 on the electronic control device 4. At the same time, a first fan assembly 5 is also disposed at the junction of the upper cavity 12 and the mounting cavity 13. The first air outlet of the first fan assembly 5 is connected to the upper cavity 12 and is disposed towards the second electrical component 3, and the first air inlet is connected to the mounting cavity 13. In this way, the electronic control device 4 can dissipate heat while the second electrical component 3 is dissipating heat, realizing multi-module heat dissipation and reducing heat accumulation. Furthermore, the mounting cavity 13 is located on one side of the heating chamber 11 in the horizontal direction, which can save the overall height space of the cooking appliance 100.

[0057] The working area is used to place the cookware and corresponds to the panel on the main body 1. The shape of the working area is not limited, and the specific shape depends on the needs of the cookware. If the cookware is a flat-bottomed pan, the working area can be set to a flat shape to better place the flat-bottomed pan. If the bottom of the cookware is round, the working area can be set to a concave shape to better place the round-bottomed pan.

[0058] The first heating device 21 is used to heat the food in the heating chamber 11. The first heating device 21 may be an electric heating wire, a heating tube or other types of heating elements.

[0059] The second heating device 31 can also take many different forms.

[0060] In some embodiments, the second heating device 31 employs an electromagnetic heating device. When the metal pot is placed in the heating zone, the electromagnetic field generates eddy currents at the bottom of the pot, thereby directly heating the pot. This design is suitable for efficient and rapid heating, and is appropriate for cooking methods such as boiling, stir-frying, and pan-frying. It should be noted that, depending on whether the pot is flat-bottomed or round-bottomed, the winding method of the electromagnetic heating device can also be set to a flat or concave shape, achieving a better heating effect on the pot.

[0061] In some embodiments, the second heating device 31 may also use a resistance heating element, through which the heat generated by the resistance heating element is transferred to the cookware, suitable for slow cooking, heat preservation and other operations.

[0062] In some embodiments, the second heating device 31 may also be an infrared heater, which directly heats the surface of the cookware or food by radiation, and is suitable for rapid heating and maintaining the surface temperature of food.

[0063] In this embodiment, by integrating two different heating methods in the same cooking appliance 100, users can choose the most suitable heating mode according to their specific cooking needs, which greatly improves cooking efficiency, flexibility and convenience. Users do not need to purchase other types of kitchen appliances, thus meeting diverse cooking needs.

[0064] It is worth noting that the first heating device 21 and the second heating device 33 in this invention can form a multi-functional integrated machine with staggered upper and lower levels in a relatively small space, such as an oven-integrated machine (i.e., cooking appliance 100). This allows multiple kitchen functions (such as cooking and baking) to be integrated into one device within a limited kitchen space, reducing the space required for individual devices, further improving space utilization, and making the kitchen layout more compact and efficient. Traditional large-scale kitchen appliances with stovetops and ovens typically occupy a large space, and their functional areas are relatively fixed and not easily adjustable according to actual needs. The staggered upper and lower levels multi-functional integrated machine is more flexible and can be adjusted according to the actual size and layout of the kitchen to meet different cooking needs. The multi-functional integrated machine can integrate multiple cooking functions, such as gas stoves, induction cookers, ovens, and steamers, which can be selected according to the user's actual needs.

[0065] Specifically, in one embodiment, the height of the main body 1 is 70mm to 150mm. This design reduces the overall volume, making the product more compact and lightweight, and easier for users to use and store in different environments. The lower height not only optimizes space utilization but is also particularly suitable for environments with limited space, such as kitchen countertops. Furthermore, in one embodiment, the installation height of the second heating device 31 within the main body 1 can be set to 20mm to 30mm. Therefore, the installation height of the first heating device 22 within the main body 1 is adapted to the thickness of the food in the heating chamber 11. For example, when the food is a pancake, the installation height of the first heating device 21 within the main body 1 can be 40mm to 50mm; when the food is a sweet potato, the installation height of the first heating device 21 within the main body 1 can be 120mm to 130mm.

[0066] The cooking appliance 100 comes in various forms, such as a grill and a stovetop.

[0067] The grill is designed for simultaneous heating on both the top and bottom, making it suitable for quickly grilling food. It is suitable for grilling various foods such as steaks, hamburgers, sandwiches, and vegetables.

[0068] The aforementioned stove-oven is a composite kitchen appliance that integrates the functions of a stove and an oven. It is suitable for various cooking operations such as boiling, stir-frying, pan-frying, and grilling.

[0069] By integrating different types of heating methods into one device, users can choose the most suitable heating mode according to their specific cooking needs, saving time and space, while also improving the overall cooking experience and significantly reducing the number of devices required, thus saving space.

[0070] It is understandable that when the first electrical device 2 and the second electrical device 3 are working simultaneously, the first heating device 21 and the second heating device 31 will affect each other, thereby affecting the performance. Therefore, in the embodiments of the present invention, please refer to... Figure 2 The cooking appliance 100 further includes a partition 6 disposed within the main body 1. The partition 6 includes a first partition portion 61 for separating the heating chamber 11 and the upper cavity 12; the second heating device 31 is disposed at the upper end of the first partition portion 61. The first partition portion 61 separates the first heating device 21 and the second heating device 31 to reduce interference. At the same time, the first partition portion 61 can support the second heating device 31, supporting the second heating device 31 on the main body 1.

[0071] The material of the separator 6 should be a material with good heat insulation effect, such as polypropylene or glass fiber.

[0072] It is understandable that if the second heating device 31 is directly mounted on the first partition 61, although the first fan assembly 5 can remove the heat from the first partition 61, some of the heat energy from the first heating device 21 will be directly transferred to the second heating device 31 through the first partition 61. To better reduce the mutual interference between the first heating device 21 and the second heating device 31, in this embodiment, please refer to... Figure 3 The lower side of the second heating device 31 is spaced apart from the upper end of the first partition 61 to form a ventilation gap; the first air outlet is positioned opposite the ventilation gap. With this arrangement, the second heating device 31 is essentially suspended on the first partition 61, allowing less heat to be transferred to the first heating device 21. Simultaneously, when the first fan assembly 5 is operating, the first air outlet faces the ventilation gap, which not only better removes heat from the second heating device 31 but also forms an air curtain between the ventilation gap, blocking heat transfer between the first heating device 21 and the second heating device 31, thereby reducing their mutual interference.

[0073] It should be noted that the support structure suspending the second heating device 31 on the first partition 61 can be integrally formed with the first partition 61 or it can be a separate component. When the support structure and the first partition 61 are separate components, it is preferable to use a support structure made of heat-insulating material, such as a ceramic column.

[0074] Furthermore, in order to reduce the heat transferred from the first heating device 21 to the second heating device 31 through the first partition 61, in an embodiment of the present invention, please refer to... Figure 2 and Figure 5 The first heating device 21 and the first partition 61 are spaced apart in the vertical direction to form a heat-insulating space 8. This arrangement uses the air within the heat-insulating space 8 as a sandwich layer to separate the first heating device 21 and the first partition 61. The low thermal conductivity of air means that very little heat from the first heating device 21 is transferred to the first partition 61, thereby reducing the impact of the second heating device 31 on the first heating device 21. It also reduces the possibility of the first partition 61 deforming due to heat.

[0075] The vertical dimension of the heat-insulating space 8 is L. It can be understood that the larger L is, the less likely the heat from the first heating device 21 will be transferred to the first partition 61, resulting in better heat insulation. To ensure the heat insulation effect, L should not be too small; otherwise, the heat-blocking effect will be very limited. Therefore, the vertical dimension of the heat-insulating space 8 is L, where L ≥ 5mm, and L can be 5mm, 6mm, 7mm, etc. Of course, L should also not be too large. With other dimensions remaining constant, the larger L is, the higher the overall height of the cooking appliance 100 will be.

[0076] To further improve the heat insulation capacity of the heat insulation space 8, in some embodiments, a heat insulation component 82 can be provided in the heat insulation space 8, wherein the heat insulation component 82 can be a silicone pad or a heat insulation cotton; in some embodiments, a phase change material can also be filled in the heat insulation space 8, so as to absorb the heat from the first heating device 21 and thereby reduce the heat transfer.

[0077] There are several ways to install the first partition 61 on the main body 1. It can be directly suspended inside the main body 1. However, this method is relatively difficult to install, and the first partition 61 is more prone to thermal deformation when the first heating device 21 and the second heating device 31 are working, affecting the stability of the overall structure. Therefore, in this embodiment of the invention, the upper end of the first heating device 21 is provided with a heat-insulating column 81 to support the lower end of the first partition 61. With this configuration, the first heating device 21 supports the first partition 61 through the heat-insulating column 81, which can support the first partition 61, reducing the possibility of thermal deformation. At the same time, the heat insulation of the heat-insulating column 81 will not transfer more heat to the first partition 61, thereby improving the stability of the first partition 61.

[0078] This design does not limit the material of the heat insulation column 81. The material of the heat insulation column 81 can be ceramic or heat insulation silicone, etc.

[0079] The first electrical component 2 and the second electrical component 3 are typically controlled by an operating unit 7. This operating unit 7, for user operation, is usually located at the upper part of the main body 1, relatively close to the second heating device 31. To reduce the heat transfer from the second heating device 31 to the operating unit 7, in an embodiment of the present invention, please refer to... Figure 3 The upper end of the first partition 61 is provided with at least one wind baffle 611, which is used to divide the upper cavity 12 into a first chamber 121 and a second chamber 122 in the longitudinal direction. The first chamber 121 is connected to the first air outlet. The second heating device 31 is disposed in the first chamber 121. The cooking appliance 100 also includes an operation part 7 disposed in the second chamber 122. The operation part 7 is used to control at least one of the first electrical device 2 and the second electrical device 3 to work through the electronic control device 4. This configuration, with the wind baffle 611 dividing the upper cavity 12 into the first chamber 121 and the second chamber 122, with the second heating device 31 located in the first chamber 121 and the operating part 7 located in the second chamber 122, can block heat transfer through the wind baffle 611, reducing the temperature of the operating part 7 during use to prevent burns to the user's hands. At the same time, it can also guide the airflow blown by the first fan assembly 5, thereby better concentrating heat dissipation on the second heating device 31. Furthermore, the operating part 7 does not require additional space, making the overall structure of the cooking appliance 100 more compact.

[0080] It should be noted that the operation unit 7 can control the first electrical device 2 to work through the electronic control device 4, or it can control the second electrical device 3 to work through the electronic control device 4, or it can control both the first electrical device 2 and the second electrical device 3 to work through the electronic control device 4.

[0081] The operating unit 7 can take many forms, including touch buttons, knobs, or a combination of touch buttons and knobs.

[0082] Of course, in actual use, the heat from the first heating device 21 and the second heating device 31 will inevitably be transferred to the operating part 7. In the embodiment of the present invention, the wind baffle 611 is provided with a notch 6111 that connects the first chamber 121 and the second chamber 122. With this configuration, after the first fan assembly 5 draws cold air into the mounting cavity 13 through the air inlet 1a, it dissipates heat from the electronic control device 4. Then, the airflow enters the first chamber 121. With the assistance of the wind baffle 611, most of the air blows towards the second heating device 31 and is discharged from the air outlet 1b. A small portion of the air enters the second chamber 122 through the notch 6111, dissipates heat from the operating part 7, and is discharged from the air outlet 1b. This ensures the heat dissipation effect on the electronic control device 4 and the second heating device 31, while also appropriately reducing the temperature of the operating part 7.

[0083] Specifically, two wind deflectors 611 are provided. One end of each wind deflector 611 corresponds to the first air outlet of the first fan assembly 5, and the other end corresponds to the air outlet 1b. The two wind deflectors 611 are adapted to the shape of the second heating device 31 to better guide the air blown out of the first air outlet to dissipate heat from the second heating device 31. The notch 6111 is provided on the wind deflector 611 near the operating part 7.

[0084] The opening is a channel for food to be placed into or removed from the heating chamber 11. The position of the mounting cavity 13 should not affect the opening and closing of the opening. That is, when the opening is set in the longitudinal direction of the heating chamber 11, the mounting cavity 13 can be set on one side of the heating chamber 11 in the transverse direction, or it can be set on the side of the heating chamber 11 in the longitudinal direction opposite to the opening.

[0085] It is understandable that in actual use, for ease of operation, the opening is usually positioned facing forward, i.e., when the opening is oriented longitudinally in the heating chamber 11. If the mounting cavity 13 could be located on one side of the heating chamber 11 in the transverse direction, the entire cooking appliance 100 would occupy more countertop space. Therefore, in this embodiment, the mounting cavity 13 is located on one side of the heating chamber 11 in the longitudinal direction; the opening is located on the side of the main body 1 that is longitudinally away from the mounting cavity 13; and the second chamber 122 is located longitudinally adjacent to the opening. With this arrangement, the mounting cavity 13 is located on the side of the heating chamber 11 opposite to the opening in the longitudinal direction, making the entire cooking appliance 100 narrower and saving more countertop space.

[0086] Specifically, in an embodiment of the present invention, if the direction from the opening to the heating chamber 11 is forward, then the second chamber 122 is located in front of the first chamber 121. In actual use, both the operation part 7 and the opening are located in front, which conforms to the user's operating habits.

[0087] It should be noted that there are multiple ways to open and close the opening, such as a drawer or a revolving door.

[0088] Specifically, in an embodiment of the present invention, the first electrical device 2 further includes a baking tray for holding food, and the baking tray can slide into or out of the heating chamber 11 from the opening.

[0089] There are various forms of the first fan assembly 5. It is understood that when the first fan assembly 5 adopts an axial flow fan, in order to make the first air outlet of the first fan assembly 5 face the second heating device 31, the rotation axis of the axial flow fan needs to be placed in the horizontal direction. This will result in the first fan assembly 5 occupying a larger size in the vertical direction, which will lead to the overall cooking appliance 100 being taller and wasting space.

[0090] In an embodiment of the present invention, the first fan assembly 5 includes a vortex fan with a rotation axis extending in the vertical direction, the first air outlet is disposed on the periphery of the vortex fan, and the first air inlet is disposed on the lower side of the vortex fan. In this way, the first assembly occupies a relatively smaller size in the vertical direction, saving space, and the overall space of the cooking appliance 100 is smaller.

[0091] As described above, the first electrical component 2, the second electrical component 3, and the electronic control device 4 all generate heat during use. The accumulated heat can be substantial, and in practical applications, a single first fan assembly 5 is insufficient to meet the heat dissipation requirements unless the first fan assembly 5 is made very large. However, this would increase costs and require a larger size. Therefore, in this embodiment, please refer to... Figure 3 The cooking appliance 100 further includes a second fan assembly 9 disposed at the lower end of the main body 1. The second fan assembly 9 has a second air outlet and a second air inlet. The second air inlet is correspondingly disposed to the air inlet 1a, and the second air outlet communicates with the mounting cavity 13. Thus, by additionally using the second fan assembly 9, the second air inlet of the second fan assembly 9 draws in cold outside air through the air inlet 1a, and then sends it into the mounting cavity 13 through the second air outlet to dissipate heat from the electronic control device 4. The first air inlet of the first fan assembly 5 further accelerates the air in the mounting cavity 13, and then sends it into the upper cavity 12 through the second air inlet, driving the heat from the second heating device 31, and finally expelling it from the air outlet 1b. By using the two fan assemblies in series, heat dissipation performance is ensured, and the two fan assemblies do not need to be too large, saving cost and space.

[0092] The first fan assembly 5 and the second fan assembly 9 can be staggered or arranged opposite each other. When staggered, the overall structure becomes more complex and requires more space for installation. Therefore, in this embodiment, the second air outlet is arranged opposite to the first air inlet, which is equivalent to the first fan assembly 5 and the second fan assembly 9 being arranged opposite each other, resulting in a simpler overall structure.

[0093] The electronic control device 4 includes a power board 41. It is understood that the power board 41 also houses many electrical components, resulting in varying heat distribution across different locations on the power board 41. To ensure effective heat dissipation for the power board 41 by the first fan assembly 5 and the second fan assembly 9, in some embodiments, the electronic control device 4 includes a power board 41 extending vertically. The power board 41 has a high-heat element 411 disposed on one side of its thickness direction, located between the second air outlet and the first air inlet. This arrangement places the high-heat element 411, i.e., the element with higher heat generation, between the second air outlet and the first air inlet, allowing for better heat dissipation from the power board 41 and ensuring effective heat dissipation.

[0094] There are several ways to place the power board 41 within the mounting cavity 13. In some embodiments, the power board 41 can be placed horizontally within the mounting cavity 13. However, since the high-heat element 411 on the power board 41 needs to be located between the second air outlet and the first air inlet, horizontal placement would obstruct airflow and affect heat dissipation. In some embodiments, the cooking appliance 100 further includes a partition 6 disposed within the main body 1. The partition 6 includes a second partition 62 for separating the heating chamber 11 and the mounting cavity 13; the power board 41 is mounted on the second partition 62 on its other side in the thickness direction. With this configuration, the power board 41 extends vertically, meaning its thickness is horizontal. This results in the power board 41 occupying a relatively small horizontal dimension, thus the mounting cavity 13 does not need to be large horizontally, reducing the horizontal dimension of the cooking appliance 100. Furthermore, since the mounting cavity 13 is located on one side of the heating chamber 11 in the horizontal direction, it has sufficient vertical space for the power board 41 to be installed. Therefore, this installation will not affect the vertical dimension of the cooking appliance 100.

[0095] The high-heat element 411 includes a heat sink and / or an insulated gate bipolar transistor.

[0096] The second fan assembly 9 can be an axial flow fan or a vortex fan. As can be seen from the above, under the same size, the air volume and air speed of the axial flow fan are greater than those of the vortex fan. Therefore, the second fan assembly 9 includes an axial flow fan whose rotation axis extends in the vertical direction, which can provide a greater air volume and air speed.

[0097] Furthermore, when the second air outlet and the first air inlet are arranged opposite each other, the electronic control device 4 includes a power board 41 extending vertically. The power board 41 has a high-heat element 411 disposed on one side of its thickness direction. When the high-heat element 411 is located between the second air outlet and the first air inlet, if the second fan assembly 9 adopts a vortex fan, it will occupy more space in the vertical direction, which may result in insufficient space in the vertical direction of the mounting cavity 13, thus requiring an increase in the overall size of the cooking appliance 100 in the vertical direction. However, when the second fan assembly 9 adopts the axial fan, the corresponding air inlet is located at the lower end of the main body 1, and the size occupied by the second fan assembly 9 in the vertical direction will be very small.

[0098] Furthermore, the second fan assembly 9 can be directly installed inside the air inlet, further reducing the space it occupies.

[0099] Specifically, in this embodiment, the second fan assembly 9 includes an axial flow fan with its rotation axis extending vertically, and the first fan assembly 5 includes a vortex fan with its rotation axis extending vertically. The rotation axis of the first fan assembly 5 is opposite to the rotation axis of the second fan assembly 9. During operation, the axial flow fan is placed horizontally and blows cold air from the air inlet 1a into the mounting cavity 13 to dissipate heat from the electronic control device 4. Then, the air is drawn in by the vortex fan and accelerated a second time before being blown towards the upper cavity 12 to dissipate heat from the second heating device 31. Finally, the air is discharged from the air outlet 1b, carrying away the heat.
