When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] Most existing combined cooking utensils are three-dimensional combinations. When working, each cooking module will generate a lot of heat, which will cause heat accumulation in the enclosed space, causing the internal temperature of the combined cooking utensils to be too high, increasing the risk of use.

[0054] The main purpose of the present invention is to provide a cooking utensil, which is intended to at least solve the problem of heat accumulation in the combined cooking utensil in the related art.

[0055] The main body 1 comprises an electric device 2, a second electric device 3, an electric control device 4 and a first fan assembly 5, wherein the main body 1 has a heating chamber 11 and an opening connected to the heating chamber 11 and capable of being opened and closed, the upper end of the main body 1 is provided with a heating zone located above the heating chamber 11, the heating zone and the heating chamber 11 are at least partially arranged opposite to each other in the up and down directions, an upper cavity 12 located between the heating zone and the heating chamber 11 is formed in the main body 1, an installation cavity 13 is formed in the main body 1 on one side in the horizontal direction of the heating chamber 11, the main body 1 is provided with an air inlet 1a connected to the installation cavity 13 and an air outlet 1b connected to the upper cavity 12; the first electric device 2 comprises a first heating device 21, the first heating device 21 is arranged on the main body 1, and is used to heat the food in the heating chamber 11; the second electrical component 3 is arranged on the upper cavity 12, and the second electrical component includes a second heating device 31, and the second heating device 31 is arranged in the upper cavity 12, and is used to heat the cookware placed in the heating zone; the electric control device 4 is arranged in the installation cavity 13, and the electric control device 4 is electrically connected to the first electrical component 2 and the second electrical component 3; the first fan component 5 is arranged at the junction of the upper cavity 12 and the installation cavity 13, and the first fan component 5 has a first air outlet and a first air inlet, the first air outlet is connected to the upper cavity 12, and is arranged toward the second electrical component 3, and the first air inlet is connected to the installation cavity 13.

[0056] In the technical solution of the present invention, the first heating device 21 of the first electrical device 2 is arranged on the main body 1 to heat the food in the heating chamber 11, the second heating device 31 of the second electrical device 3 is arranged in the upper cavity 12 to heat the pot placed in the heating zone, and the electric control device 4 used to control the first electrical device 2 and the second electrical device 3 is separately arranged in the installation cavity 13, which can reduce the influence of the heat of the first electrical device 2 and the second electrical device 3 on the electric control device 4, and at the same time, a first fan assembly 5 is also arranged at the junction of the upper cavity 12 and the installation cavity 13, the first air outlet of the first fan assembly 5 is communicated with the upper cavity 12 and is arranged toward the second electrical device 3, and the first air inlet is communicated with the installation cavity 13, so that when working, the electric control device 4 can be dissipated while the second electrical device 3 can also be dissipated, so as to realize multi-module heat dissipation and reduce heat accumulation; furthermore, the installation cavity 13 is located on one side of the heating cavity 11 in the horizontal direction, so that the height space of the entire cooking utensil 100 can be saved.

[0057] The working area is used to place the cookware, corresponding 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 plate 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 may also have various forms.

[0060] In some embodiments, the second heating device 31 is 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, so as to be suitable for efficient and rapid heating, and suitable for cooking methods such as boiling, stir-frying, and frying. It should be noted that, corresponding to the difference between a flat-bottomed pan and a round-bottomed pan, the winding method of the electromagnetic heating device can also be set to a flat shape and a concave shape, so as to achieve a better heating effect on the pot.

[0061] In some embodiments, the second heating device 31 may also use a resistance heating element, and the heat generated by the resistance heating element is transferred to the pot, which is 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 pot or food by radiation, and is suitable for quickly heating and maintaining the surface temperature of the food.

[0063] In this embodiment, by integrating two different heating methods into the same cooking utensil 100, the user can choose the most suitable heating mode according to specific cooking needs, which greatly improves cooking efficiency, flexibility and convenience. The user no longer needs to purchase other types of kitchen appliances to meet diverse cooking needs.

[0064] It is worth noting that the first heating device 21 and the second heating device 33 in the present invention can form a multifunctional all-in-one machine with upper and lower layers in a smaller space, such as a baking machine (i.e., a cooking utensil 100), so that in a limited kitchen space, the multifunctional all-in-one machine can integrate multiple kitchen functions (such as cooking, baking, etc.) into one device, reducing the space required for independent equipment, further improving space utilization, and making the kitchen layout more compact and efficient. Compared with traditional large-scale upper stove and lower baking kitchen equipment, which usually occupies a larger space and has relatively fixed functional areas, it is not easy to adjust according to actual needs. The multifunctional all-in-one machine with upper and lower layers is more flexible and can be adjusted according to the actual size and layout of the kitchen to meet different cooking needs. Among them, the multifunctional all-in-one machine can integrate multiple cooking functions, such as gas stoves, induction cookers, ovens, steamers, etc., which can be selected according to the actual needs of users.

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

[0066] The cooking appliance 100 has various forms, such as a grilling machine and a stove grill.

[0067] The grilling machine has the function of heating the upper and lower sides simultaneously, and is suitable for fast grilling of food, and is suitable for grilling steaks, hamburgers, sandwiches, vegetables and other foods.

[0068] The stove-oven is a composite kitchen appliance integrating the functions of a stove and an oven, and is suitable for performing various cooking operations such as boiling, frying, frying, and baking.

[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 equipment required and saving space.

[0070] It is understandable that when the first electrical device 2 and the second electrical device 3 are working at the same time, the first heating device 21 and the second heating device 31 will affect each other, thereby affecting the use effect. Figure 2 The cooking appliance 100 further comprises a partition 6 disposed in the main body 1, wherein the partition 6 comprises a first partition 61 for separating the heating chamber 11 from the upper cavity 12; the second heating device 31 is disposed at the upper end of the first partition 61. The first partition 61 separates the first heating device 21 and the second heating device 31 to reduce the impact, and at the same time, the first partition 61 can support the second heating device 31 and support 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, glass fiber, etc.

[0072] It can be understood that if the second heating device 31 is directly arranged on the first partition 61, although the first fan assembly 5 can take away the heat on the first partition 61, part of the heat energy on the first heating device 21 will be directly transferred to the second heating device 31 through the first partition 61. In order to better reduce the mutual influence 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 from the upper end of the first partition 61 to form a ventilation gap; the first air outlet is arranged opposite to the ventilation gap. In this way, the second heating device 31 is equivalent to being suspended on the first partition 61, and its heat can be transferred to the first heating device 21 less. At the same time, when the first fan assembly 5 is working, the first air outlet is directly facing the ventilation gap. In addition to being able to better take away the heat from the second heating device 31, it can also form a wind curtain between the ventilation gaps, blocking the heat transfer between the first heating device 21 and the second heating device 31, thereby reducing the influence between them.

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

[0074] Further, in order to reduce the amount of 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 arranged at intervals in the vertical direction to form a heat-insulating space 8. In this arrangement, the air in the heat-insulating space 8 is used as an interlayer to separate the first heating device 21 and the first partition 61, and the thermal conductivity of the air is reduced, so that the heat of the first heating device 21 can be rarely transferred to the first partition 61, thereby reducing the influence of the second heating device 31 on the first heating device 21, and also reducing the possibility of the first partition 61 being deformed by heat.

[0075] The size of the heat-insulating space 8 in the vertical direction is L. It can be understood that the larger L is, the less likely it is that the heat of the first heating device 21 will be transferred to the first partition 61, and its heat insulation capacity will be better. In order to ensure the heat insulation effect, L should not be too small, otherwise, the heat blocking effect will be very limited, that is, the size of the heat-insulating space 8 in the vertical direction is L, L ≥ 5mm, where L can be 5mm, 6mm, 7mm, etc. Of course, L should not be too large. On the basis of other dimensions remaining unchanged, the larger L is, the higher the overall height of the cooking utensil 100 will be.

[0076] In order to further improve the thermal insulation capacity of the thermal insulation space 8, in some embodiments, a thermal insulation member 82 can be arranged in the thermal insulation space 8, wherein the thermal insulation member 82 can be a silicone pad or thermal insulation cotton; in some embodiments, a phase change material can also be filled in the thermal insulation space 8 to absorb the heat from the first heating device 21 through the phase change material, thereby reducing the heat transfer.

[0077] There are many ways to set the first partition 61 on the main body 1. It can be directly suspended inside the main body 1. It is understandable that this method is relatively difficult to install, and when the first heating device 21 and the second heating device 31 are working, the first partition 61 is more susceptible to heat deformation, affecting the stability of the overall structure. Therefore, in the embodiment of the present invention, the upper end of the first heating device 21 is provided with an insulating column 81 that supports the lower end of the first partition 61; in this way, the first heating device 21 supports the first partition 61 through the insulating column 81, which can support the first partition 61 to reduce the possibility of its deformation due to heat. At the same time, the insulation of the insulating column 81 will not transfer more heat to the first partition 61, thereby improving the stability of the first partition 61.

[0078] The present design does not limit the material of the heat insulating column 81 , and the material of the heat insulating column 81 may be ceramic, or heat insulating silica gel, etc.

[0079] The first electrical device 2 and the second electrical device 3 usually need to be controlled by the operating unit 7, and the operating unit 7 is usually arranged at the upper end of the main body 1 for the convenience of the user, that is, it is relatively close to the second heating device 31. In order to reduce the heat transfer from the second heating device 31 to the operating unit 7, in the embodiment of the present invention, please refer to Figure 3 , at least one wind shield 611 is provided at the upper end of the first partition 61, and the wind shield 611 is used to divide the upper cavity 12 into a first cavity 121 and a second cavity 122 in the longitudinal direction, and the first cavity 121 is connected to the first air outlet; the second heating device 31 is arranged in the first cavity 121, and the cooking appliance 100 also includes an operating part 7 arranged in the second cavity 122, and the operating part 7 is used to control the operation of at least one of the first electrical device 2 and the second electrical device 3 through the electronic control device 4. In this arrangement, the upper cavity 12 is divided into the first cavity 121 and the second cavity 122 by the wind shielding rib 611, the second heating device 31 is arranged in the first cavity 121, and the operating part 7 is arranged in the second cavity 122. The wind shielding rib 611 can block the transfer of heat and reduce the temperature of the operating part 7 during use to avoid scalding the user's hands. At the same time, it can also guide the flow direction of the wind blown by the first fan assembly 5, so as to better concentrate the heat dissipation of the second heating device 31. Furthermore, the arrangement of the operating part 7 does not need to occupy additional space, so that the overall structure of the cooking utensil 100 is more compact.

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

[0081] The operating portion 7 may be in various forms, and may be a touch button, a knob, or a combination of a touch button and a knob.

[0082] Of course, in actual use, the heat of the first heating device 21 and the second heating device 31 will inevitably be transferred to the operating part 7. In an embodiment of the present invention, a notch 6111 connecting the first chamber 121 and the second chamber 122 is provided on the wind shield 611; in this way, the first fan assembly 5 sucks cold air from the air inlet 1a into the installation chamber 13, and then dissipates the heat of the electronic control device 4. Then the airflow enters the first chamber 121. With the assistance of the wind shield 611, most of the wind is blown to the second heating device 31 and then discharged from the air outlet 1b. A small part of the wind enters the second chamber 122 from the notch 6111, dissipates the heat of the operating part 7 and then is discharged from the air outlet 1b. This ensures the heat dissipation effect of the electronic control device 4 and the second heating device 31, while also being able to appropriately reduce the temperature of the operating part 7.

[0083] Specifically, two wind shielding ribs 611 are provided, one end of the two wind shielding ribs 611 is provided corresponding to the first air outlet of the first fan assembly 5, and the other end is provided corresponding to the air outlet 1b, and the two wind shielding ribs 611 are adapted to the shape of the second heating device 31 to better guide the wind blown out of the first air outlet to dissipate heat for the second heating device 31. The notch 6111 is provided on the wind shielding rib 611 close to the operating portion 7.

[0084] The opening is a passage for food to be placed in or taken out of the heating chamber 11, and the position of the installation cavity 13 cannot affect the opening and closing of the opening, that is, when the opening direction is set in the longitudinal direction of the heating chamber 11, the installation cavity 13 can be set on one side of the heating chamber 11 in the horizontal direction, and can also 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 the convenience of operation, when the opening is usually set forward, that is, when the opening direction is set in the longitudinal direction of the heating chamber 11, if the installation chamber 13 can be set on the side of the heating chamber 11 in the transverse direction, the overall cooking utensil 100 will occupy more countertops. Therefore, in this embodiment, the installation chamber 13 is located on the side of the heating chamber 11 in the longitudinal direction; the opening is set on the side of the main body 1 away from the installation chamber 13 in the longitudinal direction; and the second chamber 122 is set adjacent to the opening in the longitudinal direction. In this way, the installation chamber 13 is set on the side of the heating chamber 11 in the longitudinal direction opposite to the opening, so that the overall cooking utensil 100 can be narrower and save more countertops.

[0086] Specifically, in an embodiment of the present invention, when the direction from the opening to the heating chamber 11 is forward, the second chamber 122 is located in the front side of the first chamber 121. During actual use, the operating part 7 and the opening are both arranged in the 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, and the opening can be opened and closed in a drawer-like manner or in a revolving door-like manner.

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

[0089] The first fan assembly 5 has various forms. It is understandable 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. At this time, the first fan assembly 5 will occupy a larger size in the up and down directions, which will cause the overall cooking appliance 100 to be higher and waste space.

[0090] In an embodiment of the present invention, the first fan assembly 5 includes a vortex fan whose rotation axis extends in the up-down direction, the first air outlet is arranged on the peripheral side of the vortex fan, and the first air inlet is arranged on the lower side of the vortex fan, so that the size occupied by the first assembly in the up-down direction is relatively smaller, saving space, and the overall space of the cooking appliance 100 is smaller.

[0091] As can be seen from the above, the first electrical device 2, the second electrical device 3 and the electric control device 4 will generate heat during use, and the accumulated heat will be very large. In actual use, it is difficult to meet the heat dissipation requirements by only using the first fan assembly 5, unless the first fan assembly 5 is set very large, but this will lead to high costs and 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 disposed corresponding to the air inlet 1a, and the second air outlet is connected to the installation cavity 13. In this way, the second fan assembly 9 is additionally used. The second air inlet of the second fan assembly 9 sucks in the cold air from the outside through the air inlet 1a, and then sends it into the installation cavity 13 through the second air outlet to dissipate the heat of the electronic control device 4. The first air inlet of the first fan assembly 5 accelerates the air in the installation cavity 13 for a second time, and then sends it into the upper cavity 12 through the second air inlet, driving the heat on the second heating device 31, and finally discharging it from the air outlet 1b. By using the two fan assemblies in series, the heat dissipation performance is guaranteed, 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 arranged in a staggered manner or in a relative manner. When the staggered arrangement is adopted, the overall structure will be more complicated and more space will be required for installation. Therefore, in this embodiment, the second air outlet is arranged in a relative manner to the first air inlet, which is equivalent to the first fan assembly 5 and the second fan assembly 9 being arranged in a relative manner, and the overall structure will be simpler.

[0093] The electric control device 4 includes a power board 41. It is understandable that many electrical components are also arranged on the power board 41, so that the heat at various positions on the power board 41 will be different. In order to ensure the heat dissipation effect of the first fan assembly 5 and the second fan assembly 9 on the power board 41, in some embodiments, the electric control device 4 includes a power board 41 extending in the up and down directions, and the power board 41 has a high-heat element 411 arranged on one side of the thickness direction thereof, and the high-heat element 411 is located between the second air outlet and the first air inlet. In this arrangement, the high-heat element 411 on the power board 41, that is, the element with higher heat generation, is arranged between the second air outlet and the first air inlet, so that the heat on the power board 41 can be better taken away, ensuring the heat dissipation effect.

[0094] There are many ways to place the power board 41 in the installation cavity 13. In some embodiments, the power board 41 can be placed horizontally in the installation cavity 13, but 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, if it is placed horizontally, the power board 41 will hinder the flow of airflow, affecting the heat dissipation effect. In some embodiments, the cooking appliance 100 also includes a partition 6 disposed in the main body 1, and the partition 6 includes a second partition 62 for separating the heating chamber 11 and the installation cavity 13; the power board 41 is installed on the second partition 62 on the other side of the power board 41 in the thickness direction. With such arrangement, the power board 41 extends in the up-down direction, that is, its thickness direction is in the horizontal direction, which will result in that the size occupied by the power board 41 in the horizontal direction will not be very large, that is, the size of the installation cavity 13 in the horizontal direction does not need to be set very large, thereby reducing the size of the cooking utensil 100 in the horizontal direction. At the same time, since the installation cavity 13 is arranged on one side of the heating chamber 11 in the horizontal direction, the installation cavity 13 itself has enough space in the up-down direction for the power board 41 to be installed, that is, such installation will not affect the size of the cooking utensil 100 in the up-down direction.

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

[0096] The second fan assembly 9 can adopt an axial flow fan or a vortex fan. It can be seen from the above that, under the same size, the air volume and wind 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 with a rotation axis extending in the up and down directions, which can provide a larger air volume and wind speed.

[0097] Moreover, when the second air outlet is arranged opposite to the first air inlet, the electronic control device 4 includes a power board 41 extending in the up and down directions, the power board 41 has a high-heat element 411 arranged on one side in the thickness direction thereof, and 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 dimensions in the up and down directions, which may cause insufficient space in the installation cavity 13 in the up and down directions, and thus it is necessary to increase the overall dimensions of the cooking utensil 100 in the up and down directions. When the second fan assembly 9 adopts the axial flow fan, the corresponding air inlet hole is arranged at the lower end of the main body 1, and the dimension occupied by the second fan assembly 9 in the up and down directions will be very small.

[0098] Furthermore, the second fan assembly 9 can be directly arranged in the air inlet hole to further reduce the occupied space.

[0099] Specifically, in this embodiment, the second fan assembly 9 includes an axial fan with a rotation axis extending in the up-down direction, the first fan assembly 5 includes a vortex fan with a rotation axis extending in the up-down direction, and the rotation axis of the first fan assembly 5 is arranged opposite to the rotation axis of the second fan assembly 9. When working, the axial fan is placed horizontally to blow cold air upward from the air inlet 1a into the installation cavity 13 to dissipate heat for the electronic control device 4, and then the air is sucked in by the vortex fan for secondary acceleration, and then blown toward the upper cavity 12 to dissipate heat for the second heating device 31, and finally discharged from the air outlet 1b to take away the heat.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
