Description

Technical Field

[0001] This application belongs to the field of food processing equipment technology, specifically relating to a cooking utensil and cooking equipment. Background Technology

[0002] Conventional all-in-one air fryers typically use a fan to simply circulate air inside the fryer, promoting the transfer of heat generated by the heating element to the inside of the air fryer for food processing. However, the airflow generated by the fan is affected by the shape of the inner wall of the fryer or other structures, which can easily cause uneven heat distribution, making food processing difficult. Utility Model Content

[0003] This application aims to at least partially solve the technical problem of uneven heat distribution in current cooking appliances during food processing. To this end, this application provides a cooking appliance and cooking equipment.

[0004] In a first aspect, an embodiment of this application provides a cooking appliance, comprising: The base has a cavity and an air inlet and an air outlet communicating with the cavity; Specifically, along the direction from the air inlet to the air outlet, the cross-section of the cavity first decreases and then increases.

[0005] This application utilizes a combination of an air inlet, a cavity, and an air outlet within the base. Gas enters the cavity through the air inlet, flows through the cavity's turbulent flow, and then exits through the air outlet. The cavity's cross-section initially decreases and then increases, creating a Venturi effect within the cavity. This means that as gas enters the cavity through the air inlet, the channel gradually narrows, increasing the gas velocity. The direction of the velocity is restricted by the inner wall of the cavity. At the narrowest point of the cavity, the gas splits into multiple airflows with different directions. Therefore, regardless of whether the heating element is located near the air inlet or the air outlet, the heat generated by the heating element is absorbed by the airflow and evenly discharged through the air outlet. This results in a high degree of uniformity in both heat and airflow distribution of the discharged hot air. Consequently, food cooked directly or indirectly by the cooking appliance achieves similar doneness within a given time, reducing the frequency of user checks and stirring, and improving the user experience.

[0018] In an optional embodiment of this application, the heating element is located on the side of the cavity with the narrowest cross-section closest to the air outlet.

[0019] In an optional embodiment of this application, the cooking appliance further includes a heating element, the outer diameter of which is larger than the outer diameter of the air outlet.

[0020] Secondly, an embodiment of this application provides a cooking device, including the cooking utensil and a pot body that cooperates with the cooking utensil.

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figures 1-4 This application provides a cooking appliance 10, which is used to output a hot airflow to the outside for processing food or heating items. The cooking appliance 10 provided in this application provides a cooking appliance with uniform heat distribution and high stability. Figure 4 The direction of airflow in the implementation of this application is shown.

[0037] In this embodiment of the application, the cooking appliance 10 includes a base 100, the base 100 having a cavity 130 and an air inlet 111 and an air outlet 121 communicating with the cavity 130; wherein, along the direction from the air inlet 111 toward the air outlet 121, the cross-section of the cavity 130 first decreases and then increases.

[0038] The base 100 has a certain strength to protect other mechanisms installed inside it. As a type of cooking appliance, the base 100 is equipped with heating elements 180, negative pressure devices, and other mechanisms to enable it to output hot airflow to the outside. Specifically, gas enters the cavity 130 through the air inlet 111, and after turbulence in the cavity 130, it is discharged from the cavity 130 through the air outlet 121. The cross-section of cavity 130 first decreases and then increases. The airflow in cavity 130 will form a Venturi effect, that is, when the gas enters cavity 130 through air inlet 111, it forms an airflow. The channel it passes through gradually narrows, the airflow velocity increases, and the direction of the airflow velocity is restricted by the inner wall of cavity 130. After the gas passes through the narrowest part of cavity 130, the gas will become multiple airflows with different flow directions. So, regardless of whether the heating element 180 is located in cavity 130 near air inlet 111 or near air outlet 121, the heat generated by heating element 180 can be absorbed by the airflow and evenly discharged through air outlet 121. This results in a high degree of uniformity in both heat distribution and airflow distribution of the airflow discharged through air outlet 121.

[0039] When the cooking appliance 10 is used as an air fryer, its output airflow can cover a wider range and the heat distribution of the airflow is highly uniform. Food in all parts of the air fryer can absorb the heat in the airflow, so that the food in all parts of the air fryer is cooked to a similar degree in a unit of time, reducing the number of times the user needs to check and turn the food, and improving the user experience.

[0040] When the cooking appliance 10 is used as another cooking device 1 to heat the items, the cooking appliance 10 can still provide a wide range of airflow with uniform heat distribution to the items to be heated, so that the items are heated evenly.

[0041] Please see Figure 4 In some embodiments, the seat 100 includes a housing 140 and an air guide 150, the air guide 150 being disposed within the housing 140, and the middle portion of the air guide 150 protruding toward the center of the seat 100 to form a cavity 130.

[0042] The outer casing 140 is a structural component supporting the air guide 150 and other mechanisms. It has a certain load-bearing capacity to protect the mechanisms installed inside or on the outer casing 140. The middle part of the air guide 150 protrudes towards the center of the base 100. At this time, the space inside the outer casing 140 is changed by the air guide 150, forming a space whose cross-section first decreases and then increases, which is the cavity 130. Even when the air guide 150 is only provided on one side of the inner wall of the outer casing 140, the space between the inner wall of the outer casing 140 and the protruding side wall of the air guide 150 still exhibits a state of first decreasing and then increasing.

[0043] Therefore, in some embodiments, the guide may include two guide plates, which are arranged opposite to each other. The middle part of both guide plates protrudes towards the center of the seat 100. The space enclosed between the inner wall of the outer shell 140 and the protruding side walls of the two guide plates is still the cavity 130 that has become larger after being reduced in size. At this time, the cavity 130 is waist-shaped. The airflow can still have good uniformity after passing through the waist-shaped cavity 130.

[0044] Please participate Figure 4 In some embodiments, the air guide 150 is arranged around the inner annular wall of the housing 140 to make the cavity 130 hourglass-shaped.

[0045] Understandably, after the gas passes through the hourglass-shaped cavity 130, regardless of the setting of the air inlet 111, the gas velocity will be greatly increased when it passes through the smallest cross-section of the cavity 130. When it flows out from the smallest cross-section of the cavity 130, the airflow will also become multiple branch airflows with different directions. The uniformity of heat distribution and flow velocity of the airflow flowing out from the air outlet 121 will be greatly improved.

[0046] Please see Figure 4 In some embodiments, the air guide 150 has an air guide surface 151, which is an arc surface.

[0047] The air guide surface 151 is the surface on the air guide 150 that comes into contact with the airflow. When the airflow passes through the smallest cross-section of the cavity 130, part of the airflow direction is tangent to the air guide surface 151. This can prevent most of the airflow from flowing out along the air guide surface 151, which would result in a lower airflow velocity in the middle of the air outlet 121. This makes the airflow flowing out from the smallest cross-section of the cavity 130 more uniform, improves the uniformity of heat distribution and flow velocity of the airflow flowing out from the air outlet 121, and makes the airflow near the center of the shell and the airflow near the edge of the shell have similar flow velocity and heat.

[0048] Please see Figure 4 In some embodiments, an insulation cavity 160 is provided between the air guide 150 and the housing 140.

[0049] The air guide 150 protrudes towards the center of the base 100. By making the sidewall of the outer shell 140 flat, cylindrical, or making the diameter of the outer shell 140 larger than the air guide 150, a cavity can be formed between the air guide 150 and the outer shell 140. By using other structural components to prevent the cavity between the air guide 150 and the outer shell 140 from communicating with the cavity 130, or by making the air guide 150 have only a gap for air intake, the airflow within the cavity between the air guide 150 and the outer shell 140 is difficult to move, thus forming a heat-insulating cavity 160 with a heat-insulating effect. The airflow within the cavity is not easily heat-exchanged with the gas inside the heat-insulating cavity 160, nor is it easily heat-exchanged with the outside airflow. Heat exchange occurs between the gas outside the shell 140 and the gas inside the insulation cavity 160. The temperature of the gas inside the insulation cavity is not easily lost. After the part of the air guide 150 near the heating element 180 absorbs the heat radiation from the heating element 180 or the gas, the temperature of the part of the air guide 150 near the air inlet 111 will also rise. The gas entering the cavity from the air inlet 111 can absorb the heat radiation from the air guide 150, thereby preheating it. On the one hand, this can reduce heat loss and make reasonable use of the heat energy generated by the heating element 180, saving energy. On the other hand, after the gas is preheated, the temperature difference between the gas at different locations becomes smaller, and the heat distribution of the airflow flowing out from the air outlet 121 will be more uniform.

[0050] Please see Figure 1 and Figure 4 In some embodiments, the cross-section of the housing 140 first decreases and then increases along the direction from the air inlet 111 toward the air outlet 121.

[0051] Understandably, the outer casing 140 is recessed in the middle, which can be a waist-shaped or hourglass structure, making it easy for the user to hold the outer casing 140 and move the base 100. Of course, the waist-shaped or hourglass structure of the outer casing 140 has an upward-sloping surface, which can be used to install an operation panel to control the opening, closing, or functions of the cooking appliance 10. The tilt angle of the operation panel can be set according to the tilt angle of the outer casing 140, making it easy for the user to observe or click. Furthermore, the operation panel is located in the recess of the outer casing 140, making it less susceptible to scratches or impacts. When the cooking appliance 10 heats the pot body 20 and cooks food through the pot body 20, any overflow of soup or liquid from the pot body 20 is less likely to spill onto the control panel, thus preventing damage to the control panel.

[0052] In some embodiments, the outer wall of the housing 140 is provided with a handle structure 141, which is located at the minimum cross-section of the housing 140.

[0053] Please see Figures 1-3 By adding handles, the ease of operation of the cooking appliance 10 is further improved, enhancing the user experience. Specifically, two handles can be set on the outer wall of the outer shell 140. The edges of the handles do not need to extend beyond the edge of the shell to improve the aesthetics of the outer shell 140.

[0054] Please see Figures 1-3 In some embodiments, the air outlet 121 is disposed on the first end face 120 of the base 100, and the air inlet 111 is disposed on the second end face 110 of the base 100, with the second end face 110 being disposed opposite to the first end face 120.

[0055] The first end face 120 and the second end face 110 are arranged opposite each other, that is, the air inlet 111 and the air outlet 121 are arranged opposite each other. Then the airflow direction at the air inlet 111 is roughly towards the air outlet 121, which shortens the path of the airflow, reduces the loss of airflow velocity, and helps to improve the uniformity of airflow velocity at the air outlet. Of course, the higher the uniformity of airflow velocity, the higher the uniformity of heat distribution of the airflow.

[0056] In other embodiments, the air inlet 111 may be disposed on the outer ring wall of the outer casing 140 near the first end face 120. When the cooking appliance 10 is used to heat the pot body 20 and cook food through the pot body 20, the air outlet 121 of the cooking appliance 10 is facing away from the ground or tabletop. By disposing of the air inlet 111 on the outer ring wall of the outer casing 140 near the first end face 120, the uniformity of airflow velocity and heat distribution of the airflow is maintained, while ensuring that gas can enter the cavity 130 from the outside of the outer casing 140.

[0057] Please see Figure 2 In some embodiments, the air outlet 121 is disposed along the edge of the first end face 120.

[0058] Considering the air outlet 121, the diameter of the narrowest part of the cavity 130 will not be less than half the diameter of the widest part of the cavity 130. At this time, there is less airflow near the middle of the first end face 120. Therefore, the air outlet 121 is set along the edge of the first end face 120, that is, the middle of the first end face 120 is not provided with a through hole to serve as the air outlet 121, thereby making the airflow velocity discharged from the air outlet 121 more uniform.

[0059] When the cooking appliance 10 is used as part of an air fryer, the airflow from the air outlet 121 located at the edge of the second end face 110 will be guided by the side walls around the pot body 20 and gather towards the center of the pot body 20. That is, the food near the center of the pot body 20 can absorb the heat from the airflow in multiple directions, thereby enabling the food at the inner edge of the pot body 20 and the food in the center of the pot body 20 to achieve good cooking results.

[0060] Please see Figure 2 In some embodiments, the air outlet 121 is provided with a plurality of air outlet grilles 122, which are symmetrical about the center of the first end face 120.

[0061] Each air outlet grille 122 includes evenly spaced grille strips. On the one hand, the air outlet grille 122 can further improve the uniformity of the airflow velocity discharged from the air outlet 121 to a certain extent. On the other hand, the air outlet grille 122 can also block external impurities or food residues from entering the cavity 130, reducing the probability of damage to various mechanisms inside the cavity 130.

[0062] In some embodiments, each grille bar is inclined in the vertical direction, that is, there is an air guide channel between adjacent grille bars that is set at an angle to the axial direction of the cavity 130. Multiple air outlet grilles 122 are symmetrical about the center of the first end face 120. At this time, multiple airflows discharged from the air outlet 121 can form a spiral wind, that is, the airflow discharged from the air outlet 121 can have a good cooking effect on the side wall of the food, meeting the cooking needs of different foods.

[0063] Please see Figure 4 In some embodiments, the fan 170 is disposed between the air inlet 111 and the air outlet 121.

[0064] This allows hot gas to be quickly discharged from the air outlet 121, accelerating the airflow and reducing the heat radiation from the heating element 180 to other structures in the seat 100 near the air inlet 111. This not only reduces the hotness of the outer wall of the seat 100 and reduces heat waste, but also improves the cooking efficiency of the cooking appliance 10.

[0065] In some embodiments, the cooking appliance 10 also has a heating element 180 disposed between the fan 170 and the air outlet 121.

[0066] By placing the heating element 180 between the fan 170 and the air outlet 121, even if the heating element 180 radiates heat to other mechanisms within the base 100, the heat absorbed by these other mechanisms is more easily carried away by the cooler air entering the cavity 130 through the air inlet 111, thereby reducing heat waste and improving the cooking efficiency of the cooking appliance 10.

[0067] Please see Figure 4 In some embodiments, the cooking appliance 10 further includes a heating element 180, which is disposed between the air inlet 111 and the air outlet 121, with the heating element 180 positioned closer to the air outlet 121. Because the heating element 180 is positioned closer to the air outlet 121, the heat radiation from the heating element 180 to the air outlet 121 is greater than the heat radiation from the heating element 180 to the air inlet 111, thereby reducing heat loss.

[0068] Considering that the heights of the two sides of the narrowest part of the cavity 130 may be different, in some embodiments, the heating element 180 is located on the side of the narrowest part of the cavity 130 closer to the air outlet 121. Therefore, the heat radiated by the heating element 180 will be absorbed by the side wall of the narrowest part of the cavity 130, and since the airflow speed at the narrowest part of the cavity 130 is the highest within the cavity 130, the heat absorbed by the side wall of the narrowest part of the cavity 130 will also be quickly absorbed and carried away by the airflow, reducing heat loss and improving the cooking efficiency of the cooking appliance 10.

[0069] In some embodiments, the cooking appliance 10 also has a heating element 180, the outer diameter of which is larger than the outer diameter of the air outlet 121.

[0070] The heating element 180 is often selected as a heating wire arranged in a circle, so that the outer diameter of the heating element 180 is larger than the outer diameter of the air outlet 121. The airflow near the edge of the air outlet 121 can also come into contact with the heating element 180 and absorb the heat radiated by the heating element 180, which can improve the uniformity of heat distribution of the airflow discharged from the air outlet 121 of the cooking appliance 10.

[0071] Please see Figures 5-7 Based on the same inventive concept, a second aspect of this embodiment provides a cooking device 1, including a cooking utensil 10 and a pot body 20 that cooperates with the cooking utensil 10. The pot body 20 is a structural component for cooking food.

[0072] Please see Figure 6 In some embodiments, the pot body 20 has a cooking space and an opening 210. The opening 210 of the pot body 20 is detachably connected to the cooking appliance 10. The cavity 130 of the base 100 is connected to the cooking space of the pot body 20 through an air outlet 121 so that the airflow generated by the cooking appliance 10 enters the cooking space of the pot body 20. Figure 6 The direction of airflow in the implementation of this application is shown.

[0073] Understandably, the cooking appliance 10 is used as a component of an air fryer, which cooks food directly with high-temperature gas. The cooking appliance 10 can output a wider airflow with high heat distribution. Food in all parts of the pot 20 can absorb the heat from the airflow, making the food in the air fryer more evenly cooked within a unit of time. This reduces the number of times the user needs to check and turn the food, thus improving the user experience.

[0074] Please see Figure 7 In some embodiments, the air outlet 121 of the cooking appliance 10 is located on the top wall of the base 100, and the pot body 20 is mounted on top of the base 100, so that the airflow generated by the cooking appliance 10 can contact the side wall and / or bottom of the pot body 20. Figure 7The direction of airflow in the implementation of this application is shown.

[0075] The heat from the airflow comes into contact with the outer wall of the pot body 20, and heats the pot body 20 through heat conduction, thereby cooking the food inside the pot. The pot body 20 is heated evenly, which allows the food inside the pot to receive even heating. It is especially suitable for cooking methods that require high heat distribution, such as frying.

[0076] Of course, in some embodiments, by making the opening 210 of the pot body 20 detachably connected to the air outlet 121 of the cooking appliance 10, and by making the bottom of the pot body 20 gapped with the air outlet 121 of the cooking appliance, for example, by providing multiple first protrusions 123 at the air outlet 121 of the cooking appliance 10, or by providing multiple second protrusions 220 on the bottom surface of the pot body 20, the pot body 20 can be adapted to the cooking appliance 10 to have multiple functions, expand various cooking scenarios, and improve user satisfaction.
