[0003] In view of this, it is necessary to provide a frying and grilling utensil to address the above problems so as to improve the cooking effect.

[0004] The utility model firstly provides a grilling utensil, comprising: an upper grilling plate assembly, the upper grilling plate assembly comprising an upper grilling plate and an upper heating assembly for heating the upper grilling plate; a lower grilling plate assembly, the upper grilling plate assembly can be movably connected to the lower grilling plate assembly, the lower grilling plate assembly comprises a lower grilling plate and a lower heating assembly for heating the lower grilling plate, the upper grilling plate can cooperate with the lower grilling plate to form a closed cooking cavity; and a hot air assembly, arranged on the upper grilling plate assembly or the lower grilling plate assembly, the hot air assembly comprises a fan and an air guide duct, the air inlet of the air guide duct is connected with the fan, the air outlet of the air guide duct is connected with the cooking cavity, and the flow area of ​​the air guide duct gradually decreases in the direction from the air inlet of the air guide duct to the air outlet.

[0005] In the above-mentioned frying and grilling appliance, outside air can enter the air duct from the air inlet under the action of the fan, the upper heating component or the lower heating component or other separate heating body can heat the air duct, and heat the air flowing through the air duct to form hot air, and the hot air enters the cooking cavity, takes away the moisture in the cooking cavity, and makes the food taste crispy, and the hot air can also increase the temperature of the side of the food, improving the cooking effect of the side of the food; and, since the flow area of ​​the air duct gradually decreases in the direction from the air inlet to the air outlet, the air temperature at the air outlet is further increased when the air heat in the air duct remains unchanged, and the high-temperature hot air makes the food taste crisper, and will not affect the temperature of the cooking cavity, thereby avoiding heat loss in the cooking cavity.

[0006] In one of the embodiments, the middle portion of the air duct is provided with the air inlet connected to the outlet of the fan, and the ends of the air duct are respectively provided with an air outlet.

[0007] Such an arrangement allows the hot air in the cooking cavity to be evenly distributed, thereby improving the efficiency of discharging moisture in the cooking cavity, and also preventing the hot air from entering only one side of the cooking cavity, causing uneven heating of the food in the cooking cavity, thereby affecting the cooking effect.

[0008] In one embodiment, the flow area of ​​the air outlet is S1, and the flow area of ​​the air inlet is S2, then S1≤S2 / 8.

[0013] Such an arrangement can ensure the heating effect of the upper heating component or the lower heating component on the air in the air duct while preventing the air duct from affecting the heating effect of the upper heating component and the lower heating component on the upper baking tray and the lower baking tray.

[0014] In one of the embodiments, the bottom wall of the air guide duct is attached to the upper heating component or the lower heating component.

[0015] Such a configuration allows the air duct to fully contact the upper heating component or the lower heating component, increasing the contact area, and allows the gas inside the air duct to be heated evenly, thereby improving the heating effect of the upper heating component or the lower heating component on the air duct.

[0016] In one embodiment, the hot air assembly is arranged on the upper baking tray assembly, and the upper baking tray assembly also includes a reflective cover and a cover body, the upper heating assembly is arranged between the upper baking tray and the reflective cover, the air guide duct is arranged between the reflective cover and the cover body, and the cover body is provided with a avoidance hole connected to the inlet of the fan.

The cover body can protect components such as the hot air component and the upper heating component. Moreover, the air guide duct is arranged between the reflective cover and the cover body, so as to reasonably utilize the existing space in the upper baking pan assembly without increasing the overall volume of the frying and grilling appliance.

[0018] In one of the embodiments, the upper baking tray assembly further comprises a cover body, the cover body is provided with an air inlet connected to the inlet of the fan, and the cover body covers the avoidance hole.

[0019] With such arrangement, the cover body can prevent foreign matter such as dust and water vapor from entering into the space between the upper grill plate and the cover body or into the fan through the avoidance hole, thereby protecting various components in the grilling utensil.

[0020] In one of the embodiments, the cover body includes a top surface and a side surface, the air inlet is arranged on the side surface of the cover body, and the top surface covers the avoidance hole.

[0021] Such an arrangement can further prevent foreign matter such as dust and water vapor from entering the space between the upper baking tray and the cover body or entering the fan through the air inlet, thereby achieving better dust prevention and protection effects.

[0022] In one of the embodiments, an adapter is provided on the reflector, and the adapter connects the cooking cavity with the air outlet of the air duct.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0035] Frying and roasting appliances, such as frying and roasting machines, have become common cooking appliances in people's daily lives because of their multiple functions of frying, roasting and baking. Existing frying and roasting machines include an upper baking tray assembly and a lower baking tray assembly that can be movably connected to the upper baking tray assembly, and a cooking cavity is formed between the upper and lower baking trays to perform multiple functions such as making pancakes, frying and roasting vegetables, and cooking meat. In the frying and roasting mode with the upper and lower baking trays buckled together, excessive water vapor retained in the cooking cavity is likely to affect the taste of the food.

[0036] In order to solve the above problems, Figures 1 to 7 As shown, the utility model provides a frying and grilling utensil, which can quickly discharge moisture in the cooking cavity without affecting the temperature of the grilling plate, and can fully utilize the energy of the heating component to improve the cooking effect.

[0037] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, the frying and grilling device includes an upper grill pan assembly 10, a lower grill pan assembly 20 and a hot air assembly 30, wherein: the upper grill pan assembly 10 includes an upper grill pan 11 and an upper heating assembly (not shown) for heating the upper grill pan 11; the upper grill pan assembly 10 can be movably connected to the lower grill pan assembly 20, the lower grill pan assembly 20 includes a lower grill pan 21 and a lower heating assembly (not shown) for heating the lower grill pan 21, the upper grill pan 11 can cooperate with the lower grill pan 21 to form a closed cooking cavity; the hot air assembly 30 is arranged on the upper grill pan assembly 10, the hot air assembly 30 includes a fan 31 and an air duct 32, the air inlet 321 of the air duct 32 is connected to the fan 31, the air outlet 322 of the air duct 32 is connected to the cooking cavity, and the flow area of ​​the air duct 32 gradually decreases along the direction from the air inlet 321 of the air duct 32 to the air outlet 322.

[0038] In the grilling device provided by the embodiment of the utility model, the outside air can enter the air duct 32 from the air inlet 321 under the action of the fan 31. In addition to heating the food in the cooking cavity during operation, the upper heating assembly can also increase the temperature inside the upper baking tray assembly 10, thereby heating the air duct 32 and heating the air flowing through the air duct 32 to form hot air. The hot air enters the cooking cavity, takes away the moisture in the cooking cavity, and makes the food crispy. The hot air can also increase the temperature of the side of the food, thereby improving the cooking effect of the side of the food. In addition, since the flow area of ​​the air duct 32 gradually decreases in the direction from the air inlet 321 to the air outlet 322, the air flow area of ​​the air duct 32 gradually decreases. Therefore, when the air heat in the air duct 32 remains unchanged, the air temperature at the air outlet 322 is further increased. The high-temperature hot air makes the food taste crisper, and does not affect the temperature of the cooking cavity, thereby avoiding the loss of heat in the cooking cavity.

[0039] In another embodiment, the hot air assembly 30 may also be disposed on the lower grill assembly 20, and the air duct 32 and the air in the air duct 32 are heated by the lower grill assembly 20. Moreover, the hot air assembly 30 utilizes the original upper heating assembly or the lower heating assembly to heat the air duct 32 and the air in the air duct 32, and can fully utilize the energy of the upper heating assembly or the lower heating assembly.

[0040] Of course, in other embodiments, when the hot air assembly 30 is disposed on the upper baking tray assembly 10 or the lower baking tray assembly 20, the hot air assembly 30 may also include a separate heating element (not shown) and heat the air through the heating element air duct 32 and the air in the air duct 32.

[0041] like Figure 7 As shown, the bottom wall of the air duct 32 is attached to the upper heating assembly or the lower heating assembly, so that the air duct 32 can fully contact with the upper heating assembly or the lower heating assembly, increase the contact area between the air duct 32 and the upper heating assembly or the lower heating assembly, and after the bottom wall of the air duct 32 is heated, the gas inside the air duct 32 can be evenly heated and heated, thereby improving the heating effect of the upper heating assembly or the lower heating assembly on the air duct 32.

[0042] like Figure 7 As shown, the air duct 32 is attached to the side of the upper heating assembly facing away from the upper grill pan 11 or to the side of the lower heating assembly facing away from the lower grill pan 21. Thus, while ensuring the heating effect of the upper heating assembly or the lower heating assembly on the air duct 32 and the air in the air duct 32, the air duct 32 is prevented from affecting the heating effect of the upper heating assembly or the lower heating assembly on the upper grill pan 11 and the lower grill pan 21.

[0043] like Figure 1 and Figure 5 As shown, in one embodiment, the hot air assembly 30 is arranged on the lower grill assembly 20, and the lower grill assembly 20 also includes a base 22, and the lower heating assembly is located between the lower grill 21 and the base 22. The lower grill assembly 20 also includes a lower reflector (not shown), and the lower heating assembly is arranged between the lower grill 21 and the lower reflector, and the lower reflector can reflect the heat radiated from the lower heating assembly toward the lower reflector to the lower grill 21. The air duct 32 is arranged between the lower reflector and the base 22, and because the lower reflector will heat up under the action of the lower heating assembly, the air duct 32 can be heated by the lower reflector.

[0044] In order to further improve the heating effect, the air duct 32 can be attached to the lower reflector so that the lower reflector and the air duct 32 can directly transfer heat to heat the air in the lower reflector, that is, the air duct 32 is indirectly in contact with the lower heating assembly through the lower reflector to ensure heating efficiency. In addition, the lower reflector and the air duct 32 can also be made of metal, so that metal heat transfer can be achieved between the lower heating assembly, the lower reflector and the air duct 32 to heat the air in the air duct 32, ensuring heating efficiency and improving the heating effect.

[0045] like Figure 1 and Figure 5As shown, in the illustrated embodiment, the hot air assembly 30 is arranged on the upper grill assembly 10, and the upper grill assembly 10 further includes a reflector 12 and a cover 13, the upper heating assembly is arranged between the upper grill 11 and the reflector 12, the air duct 32 is arranged between the reflector 12 and the cover 13, and the cover 13 is provided with an escape hole 131 connected to the inlet 311 of the fan 31. The cover 13 can protect the hot air assembly 30, the upper heating assembly and other components inside the upper grill assembly 10. Since other components such as the upper heating assembly need to be installed in the upper grill assembly 10, there is usually a large space between the upper grill 11 and the cover 13. The reflector 12 and the air duct 32 are arranged between the upper grill 11 and the cover 13, which can reasonably utilize the existing space in the upper grill assembly 10 without increasing the overall volume of the grilling utensil. The avoidance hole 131 allows outside air to enter the space between the upper baking pan 11 and the cover 13, and the fan 31 can introduce the cold air from the outside into the air duct 32 through the avoidance hole 131. The reflector 12 can reflect the heat radiated from the upper heating assembly toward the reflector 12 to the upper baking pan 11, so as to improve the heating efficiency of the heating tube and avoid heat loss. At the same time, since the reflector 12 will heat up under the action of the heating tube, the air duct 32 can be heated by the reflector 12.

[0046] In order to further improve the heating effect, the air duct 32 can be attached to the reflector 12, so that the reflector 12 and the air duct 32 can directly transfer heat to heat the air in the air duct 32, that is, the air duct 32 is indirectly in contact with the upper heating component through the reflector 12, so as to ensure the heating efficiency. In addition, the reflector 12 and the air duct 32 can also be made of metal, so that metal heat transfer can be achieved between the upper heating component, the reflector 12 and the air duct 32 to heat the air in the air duct 32, so as to ensure the heating efficiency and improve the heating effect.

[0047] Of course, in other embodiments, the air duct 32 may also be in direct contact with the side of the upper heating component facing away from the upper baking tray 11 or the side of the lower heating component facing away from the lower baking tray 21 to ensure the heat transfer effect between the upper heating component or the lower heating component and the air duct 32.

[0048] like Figure 1 and Figure 3 As shown, the reflector 12 is provided with an adapter 121, which connects the cooking cavity with the air outlet 322 of the air duct 32. The adapter 121 is used to introduce the hot air in the air duct 32 into the cooking cavity. When the air duct 32 is damaged or needs to be replaced, it is only necessary to disconnect the air duct 32 from the adapter 121, which will not affect the normal use of the reflector 12, so that the air duct 32 can be easily disassembled or replaced.

[0049] like Figure 1 and Figure 3As shown, the upper baking tray 11 is provided with an air inlet channel 111 connected to the adapter 121, and the cooking cavity is connected to the adapter 121 through the air inlet channel 111. The hot air in the air duct 32 can enter the cooking cavity through the air outlet 322, the adapter 121 and the air inlet channel 111 in sequence.

[0050] In the illustrated embodiment, the back of the upper baking tray 11 is provided with an air inlet passage 111 formed by a hollow boss 112, and the boss 112 and the air duct 32 are respectively sleeved at the two ends of the adapter 121. In this way, the reliability and sealing of the connection between the air duct 32, the adapter 121 and the boss 112 can be ensured. Along the flow direction of the hot air, the air duct 32, the adapter 121 and the boss 112 can form a closed space, so that the hot air in the air duct 32 can all enter the cooking cavity through the air inlet passage 111, thereby avoiding the loss of heat and improving the utilization rate of energy; at the same time, it can also avoid the hot air in the air duct 32 from leaking into other areas between the upper baking tray 11 and the cover 13 to affect the normal operation of other components in the upper baking tray assembly 10.

[0051] Of course, in other embodiments, the end of the adapter 121 away from the air outlet 322 of the air duct 32 can also be directly extended into the air inlet channel 111 or into the cooking cavity through the air inlet channel 111, as long as the hot air in the air duct 32 can be discharged into the cooking cavity through the adapter 121 and the air inlet channel 111.

[0052] like Figure 1 and Figure 4 As shown, in order to facilitate cleaning, maintenance or disassembly of other components such as the fan 31, the size of the avoidance hole 131 may be relatively large, but this will cause foreign matter such as dust and water vapor from the outside to enter the space between the upper grill 11 and the cover 13 or enter the fan 31 through the avoidance hole 131, thereby affecting the normal use of the grilling utensil. Therefore, the upper grilling utensil assembly 10 also includes a cover 14, on which an air inlet 1421 connected to the inlet 311 of the fan 31 is opened, and the cover 14 is covered on the avoidance hole 131. The size of the air inlet 1421 can be relatively small, as long as it is ensured that the outside air can enter the fan 31 through the air inlet 1421. The cover 14 can prevent foreign matter such as dust and water vapor from the outside from entering the space between the upper grill 11 and the cover 13 or entering the fan 31 through the avoidance hole 131, thereby protecting the various components in the grilling utensil, and the fan 31 will not be exposed, ensuring a neat appearance.

[0053] The cover body 14 and the lid body 13 can be detachably connected by means of snap-fit, screw connection, plug-in connection, etc., which ensures the stability and reliability of the connection between the cover body 14 and the lid body 13 while facilitating the user to disassemble and assemble the cover body 14.

[0054] like Figures 4 to 6As shown, the cover body 14 includes a top surface 141 and a side surface 142, and an air inlet 1421 is arranged on the side surface 142 of the cover body 14. Since foreign matter such as dust and water vapor from the outside usually falls to the top surface 141 of the cover body 14 under the action of gravity, the air inlet 1421 is arranged on the side surface 142 of the cover body 14 to further prevent foreign matter such as dust and water vapor from the outside from entering the space between the upper baking tray 11 and the cover body 13 or entering the fan 31 through the air inlet 1421, and the dustproof and protective effects are better. Among them, the number of air inlets 1421 can be one, two or more, and the multiple air inlets 1421 are arranged at intervals along the circumference of the side surface 142 to ensure that sufficient air enters the space between the upper baking tray 11 and the cover body 13 through the air inlet 1421.

[0055] like Figure 2 and Figure 7 As shown, in the illustrated embodiment, an air inlet 321 communicating with the outlet 312 of the fan 31 is provided in the middle of the air duct 32, and an air outlet 322 is provided at each end of the air duct 32. The fan 31 can introduce outside air into the air duct 32 through the air inlet 321, and the air entering the air duct 32 will flow toward both sides of the air duct 32, and enter the cooking cavity from both sides of the cooking cavity through the air outlets 322 at both ends of the air duct 32, so that the hot air in the cooking cavity is evenly distributed, thereby improving the efficiency of discharging moisture in the cooking cavity, and also preventing the hot air from entering only one side of the cooking cavity, causing uneven heating of the food in the cooking cavity, thereby affecting the cooking effect.

[0056] Of course, in other embodiments, the air duct 32 may be provided with only one air outlet 322, or multiple air outlets 322 may be provided on the air duct 32. For example, the air duct 32 may be provided with multiple branches, and an air outlet 322 may be opened on each branch. As long as the air duct 32 can discharge hot air into the cooking cavity, the embodiments of the utility model are not specifically limited here.

[0057] The number and arrangement positions of the adapters 121 and the bosses 112 are arranged correspondingly to the air outlets 322 of the air duct 32 .

[0058] like Figure 2 and Figure 7 As shown, the flow area of ​​the air outlet 322 is S1, and the flow area of ​​the air inlet 321 is S2, then S1≤S2 / 8. It can be understood that since the air inlet 321 of the air duct 32 needs to be sealed and connected to the outlet 312 of the fan 31, the flow area of ​​the air inlet 321 is the same as the flow area of ​​the outlet 312 of the fan 31, that is, both are S2. Figure 2The figure shows the flow area S2 of the outlet 312 of the fan 31. The ratio S1 / S2 of S1 to S2 can be any value less than or equal to 1 / 8, such as 1 / 8, 1 / 9, 1 / 10, 1 / 11, etc. When the flow area S1 of the air outlet 322 and the flow area S2 of the air inlet 321 satisfy the above relationship, the temperature of the air in the air duct 32 can rise rapidly when it flows from the air inlet 321 to the air outlet 322, thereby further improving the heating efficiency of the air in the air duct 32, increasing the temperature of the air flowing from the air outlet 322 to the cooking cavity, and ensuring the cooking effect.

[0059] When the cross section of the air outlet 322 is a circle as shown in the figure, the flow area S1 of the air outlet 322 is the area of ​​the circle; when the cross section of the air inlet 321 is a rectangle as shown in the figure, the flow area S2 of the air inlet 321 is the area of ​​the rectangle. Of course, the cross section of the air outlet 322 and the cross section of the air inlet 321 can also be other regular or irregular shapes, and the embodiment of the utility model does not make specific restrictions here.

[0060] like Figure 2 As shown, the air duct 32 has an air outlet end surface 323, and the air outlet 322 is opened on the air outlet end surface 323. The cross-sectional area of ​​the air outlet end surface 323 is S3, then S3≤S2 / 4. Among them, the ratio S3 to S2 S3 / S2 can be 1 / 4, 1 / 5, 1 / 6, 1 / 7, etc., any value less than or equal to 1 / 4 and greater than or equal to 1 / 8. It can be understood that when the cross-sectional area S3 of the air outlet end surface 323 is reduced, the contact area between the air duct 32 and the upper heating component or the lower heating component will also be reduced. Therefore, when the cross-sectional area S3 of the air outlet end surface 323 and the flow area S2 of the air inlet 321 satisfy the above relationship, it can ensure that the temperature of the air in the air duct 32 can rise quickly when it flows from the air inlet 321 to the air outlet 322, and it can also ensure the heating effect of the upper heating component or the lower heating component on the air duct 32 and the air in the air duct; at the same time, it can also ensure that there is enough space on the air outlet end surface 323 to open the air outlet 322. Among them, the air outlet end surface 323 is the end surface of the air duct 32 that is farthest from the air inlet 321, and the cross section of the air outlet end surface 323 is a cross section perpendicular to the air flow direction in the air duct 32.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
