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 heating bases primarily heat cookware placed on them through heat conduction during operation. While the heating element inside the base generates heat to heat the cookware, it also radiates heat to other components within the base. As heat accumulates, prolonged exposure to high temperatures within the heating base will cause it to age prematurely, affecting its normal operation. Utility Model Content

[0007] This application, by setting an air outlet at the edge of the mounting surface of the cooking appliance, allows the heating device to radiate heat to the air inside the cavity and the base. Through the heat conduction of the base and the removal of heat by the hot air, the cooling speed of the cooking appliance can be increased, thereby slowing down the aging process of the base and its internal structure. Furthermore, when the cooking appliance is cooking using the heating device, the hot air flowing out of the air outlet comes into contact with the outer wall of the pot. When the temperature of the outer wall of the pot is lower than that of the hot air, the hot air will exchange heat with the outer wall of the pot, raising the temperature of the pot. When the temperature of the outer wall of the pot is not lower than that of the hot air, the hot air close to the outer wall of the pot will isolate the cold air from the pot, thereby maintaining the temperature of the outer wall of the pot, reducing heat waste, and improving the thermal efficiency of the cooking appliance.

[0018] In an optional embodiment of this application, the top surface of the partition is higher than the top of the air outlet.

[0019] In an optional embodiment of this application, the cooking appliance further includes a fan, which is disposed within the cavity and the air outlet of the fan faces the air outlet.

[0020] In an optional embodiment of this application, the cavity is configured in the shape of an hourglass, and the fan blades are higher than the narrowest point of the cavity.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Please see Figures 1-3 This application provides a cooking appliance 10, which can be used to heat a pot 20 placed on top of it, and the cooking appliance 10 does not easily accumulate heat inside the pot 20 during the heating process.

[0036] In this embodiment of the application, the cooking appliance 10 includes a base 100 and a heating device 180. The base 100 has a cavity 130 and a mounting surface 120. The mounting surface 120 is used to place the pot 20. The mounting surface 120 has an air outlet 121 that connects the outside of the base 100 and the cavity 130. The air outlet 121 is located near the edge of the mounting surface 120. The heating device 180 is installed inside the cavity 130.

[0037] The heating device 180 transfers the generated heat to the mounting surface 120 or the pot 20 placed on the mounting surface 120 by means of thermal radiation or thermal conduction. The mounting surface 120 is used to place the pot 20, so it can be understood that the mounting surface 120 is located on the top surface of the base 100.

[0038] An air outlet 121 located at the edge of the mounting surface 120 connects the cavity 130 of the seat 100 to the outside of the seat 100. When the heating device 180 radiates heat to the seat 100 and other mechanisms inside the seat 100, causing the temperature inside the cavity 130 to rise, the air inside the cavity 130 absorbs heat, its density decreases, and the hot air flows upward, eventually dissipating from the air outlet 121 to the outside of the cavity 130. In other words, the seat 100 of this application dissipates heat from its interior through the air outlet 121 located on the top surface of the seat 100, reducing the aging rate of the seat 100 and the mechanisms installed inside it. Furthermore, because the air outlet 121 is located at the edge of the mounting surface 120, when the hot air inside the cavity 130 flows outward, the hot air can maintain an upward trend for a period of time.

[0039] When the heating device 180 of the cooking appliance 10 is turned off, the heating device 180 generates heat and radiates heat to the air inside the cavity 130 and the seat 100. Through the heat conduction of the seat 100 and the removal of heat by the hot air, the cooling speed of the cooking appliance 10 can be increased, thereby slowing down the aging process of the seat 100 and its internal structure.

[0040] When the cooking appliance 10 is cooking via the heating device 180, the air inside the cavity 130 absorbs heat and forms hot air, which flows out from the air outlet 121. This hot air can come into contact with the outer wall of the pot 20 placed on the mounting surface 120. When the temperature of the outer wall of the pot 20 is lower than the temperature of the hot air, the hot air will exchange heat with the outer wall of the pot 20, and the outer wall of the pot 20 will heat up after absorbing heat. When the temperature of the outer wall of the pot 20 is not lower than the temperature of the hot air, the hot air close to the outer wall of the pot 20 can isolate the cold air from the pot 20, thereby maintaining the temperature of the outer wall of the pot 20, reducing heat waste, and improving the thermal efficiency of the cooking appliance 10.

[0041] Please see Figure 1 In some embodiments, the air outlet 121 is arranged around the mounting surface 120.

[0042] By setting air vents 121 around the installation, on the one hand, the area of ​​the air vents 121 can be increased, accelerating the outflow of hot air from the cavity 130; on the other hand, when the hot air flows out from the annular air vents 121, the hot air will also form a ring. When the cooking appliance 10 is cooking through the heating device 180, the pot 20 can be surrounded by hot air. At this time, the hot air plays a supplementary cooking effect, that is, it can continuously heat the bottom or side walls of the pot 20 or reduce the heat loss of the pot 20.

[0043] Please see Figure 1In some embodiments, the air outlet 121 has a plurality of sub-air outlets 121a, which are spaced apart around the mounting surface 120.

[0044] By setting multiple sub-air outlets 121a, the multiple sub-air outlets 121a are arranged to form a ring-shaped air outlet 121. Structural components are provided between the sub-air outlets 121a to avoid reducing the load-bearing capacity of the mounting surface 120. In order to improve the efficiency of hot air exhaust while ensuring the strength of the mounting surface 120, grilles 122 can also be set on the multiple sub-air outlets 121a. The grille 122 holes can guide the hot air, and the grille 122 can also block external impurities or food residue generated during cooking from entering the cavity 130, reducing the probability of damage to the various mechanisms inside the cavity 130.

[0045] Please see Figure 1 In some embodiments, the edge of the mounting surface 120 is provided with a guide 124, which surrounds the air outlet 121.

[0046] Considering that the size and bottom shape of different cookware 20 will affect the flow direction of hot air from the air outlet 121, for example, if the bottom of the cookware 20 covers most of the air outlet 121, the hot air can only flow out from the small gap between the air outlet 121 and the cookware 20. At this time, the air pressure in the cavity 130 increases, which will cause the hot air flowing out of the gap to have a radial velocity towards the seat 100, resulting in poor hot air supplementing the cooking effect of the cookware 20. Therefore, a guide 124 is provided at the edge of the mounting surface 120. The guide 124 changes the flow direction of the hot air towards the side wall of the mounting surface 120, so that the hot air can get as close as possible to the cookware 20 to supplement the cooking effect on the outer wall of the cookware 20.

[0047] Please see Figure 1 In some embodiments, a positioning element 123 is provided on the edge of the mounting surface 120, and one end of the positioning element 123 is located at the air outlet 121.

[0048] The positioning component 123 is a structural component used to limit the position of the cookware 20 on the mounting surface 120. It has a certain strength. When the cookware 20 is placed on the mounting surface 120 and the side wall of the cookware 20 is in contact with the end of the positioning component 123 facing the center of the mounting surface 120, there will be at least a gap between the cookware 20 and the air outlet 121 for the hot air to flow out. This can ensure the heat dissipation function of the cooking appliance 10 and the operation of the supplementary cooking function of the cooking appliance 10 for the cookware 20.

[0049] Of course, in some embodiments, the positioning element 123 includes at least three positioning blocks, one end of each positioning block is disposed at the edge of the mounting surface 120, and one end of each positioning block is located at the air outlet 121. When the bottom diameter of the pot 20 is small, the bottom of the pot 20 can be located between the three positioning blocks. In this case, hot air can flow out from all sides of the air outlet 121 to supplement the cooking of the pot 20. When the bottom diameter of the pot 20 is large, the pot 20 can be directly mounted on the top of multiple positioning blocks, thereby creating a gap between the air outlet 121 and the bottom of the pot 20 for hot air to flow out. In this case, the hot air can supplement the cooking of the bottom and side walls of the pot 20.

[0050] Please see Figure 2 In some embodiments, the seat 100 also has a support surface 110 disposed opposite to the mounting surface 120, and the support surface 110 and / or the side of the seat 100 near the support surface 110 is provided with an air inlet 111 communicating with the outside of the seat 100 and the cavity 130.

[0051] The support surface 110 is positioned opposite the mounting surface 120, which is used to place the cookware 20. The support surface 110 is the end of the base 100 closest to the countertop, tabletop, or other surface where the cooking appliance 10 is placed. The support surface 110 can directly contact the surface, or support feet can be provided on the support surface 110 to create a gap between it and the surface where the cooking appliance 10 is placed. An air inlet 111 is provided on the side of the support surface 110 and / or the base 100 near the support surface 110, meaning the height of the air inlet 111 is lower than the height of the air outlet 121. When the heating device 180 is running, the air temperature outside the base 100 is lower than the air temperature inside the cavity 130. The cold air outside the base 100 rises due to its lower density, and enters the cavity 130 through the air inlet 111, absorbing heat from other components within the cavity 130, and ultimately dissipates as hot air from the air outlet 121. Understandably, the cold air outside the base 100 can continuously enter the cavity 130, keeping the cavity 130 at a lower temperature and slowing down the high-temperature aging of other components inside the base 100. Furthermore, when the cold air enters the cavity 130 from the air inlet 111, it pushes the hot air upwards, improving the efficiency of hot air exhaust and thus enhancing the efficiency of reheating the cookware 20.

[0052] Please see Figure 2 In some embodiments, the support surface 110 has a boss 112 in the middle, and the air inlet 111 is arranged around the boss 112 so that the air inlet 111 is arranged opposite to the air outlet 121.

[0053] By providing a boss 112 on the support surface 110, a gap is created between the support surface 110 and the plane. The air inlet 111 and the air outlet 121 are arranged opposite each other, shortening the movement path of air from entering the cavity 130 to exiting from the air outlet 121. This allows the air to move more rapidly within the cavity 130, significantly improving the heat dissipation efficiency of the base 100.

[0054] In some embodiments, the support surface 110 has a slope 113 inclined towards the mounting surface 120 on the side near the boss 112, and the air inlet 111 is disposed on the slope 113. By setting the slope 113, the area of ​​the air inlet 111 is increased, improving the efficiency of cold air entering the cavity 130. Furthermore, the air inlet 111 and the air outlet 121 are arranged opposite each other. When impurities or food residue fall into the cavity 130 from the air inlet 111, they easily accumulate at the air inlet 111 under the influence of gravity. Users can then easily remove the impurities or food residue by gently brushing the air inlet 111 with a brush, making cleaning convenient and providing a better user experience.

[0055] Please see Figure 3 In some embodiments, the heating device 180 is positioned near the air outlet 121.

[0056] The heating device 180 is positioned close to the air outlet 121. Therefore, the heat radiation from the heating device 180 to the air outlet 121 is greater than the heat radiation from the heating device 180 to the air inlet 111. This not only helps the heating device 180 heat the pot 20 on the mounting surface 120 and reduces heat loss, but also reduces the aging effect of the heat generated by the heating device 180 on other components in the cavity 130.

[0057] In some embodiments, a partition 125 is also provided in the middle of the mounting surface 120. The partition 125 is used to conduct or radiate part of the heat generated by the heating device 180 to one side of the partition 125; the air outlet 121 is arranged around the partition 125.

[0058] The partition 125 can be a metal plate. When the heating device 180 inside the cavity 130 is in operation, it transfers heat to the partition 125, and then to the cookware 20 through the partition 125. In some embodiments, the partition 125 is a light-transmitting element. When the heating device 180 inside the cavity 130 is in operation, the heat it generates can be directly transferred to the cookware 20 through the light-transmitting plate by thermal radiation.

[0059] In some embodiments, the top surface of the partition 125 is higher than the top of the air outlet 121.

[0060] When the cookware 20 is placed on the partition 125, the partition 125 can create a gap between the cookware 20 and the air outlet 121, so that the hot air discharged from the air outlet 121 can gradually move along the bottom wall of the cookware 20 to the periphery of the cookware 20, isolating the cold air from the cookware 20, thereby maintaining the temperature of the outer wall of the cookware 20, reducing heat energy waste, and improving the thermal efficiency of the cooking appliance 10.

[0061] In some embodiments, the cooking appliance 10 also includes a fan 170 disposed within the cavity 130, with the fan 170 venting towards the air outlet 121.

[0062] The rotating fan 170 accelerates the movement of air in the cavity 130 from the air inlet 111 to the air outlet 121, carrying away a large amount of heat in a short time, improving cooling efficiency and reducing the aging rate of the mechanism in the seat 100.

[0063] Please see Figure 3 In some embodiments, the cavity 130 is arranged in an hourglass shape, and the fan blades of the fan 170 are higher than the narrowest part of the cavity 130.

[0064] The hourglass-shaped cavity 130 has a cross-section that first decreases and then increases. Hot air within the cavity 130 will experience a Venturi effect; that is, as the gas enters the cavity 130 through the inlet 111, the channel it traverses gradually narrows, increasing the gas velocity. Furthermore, the direction of the velocity is restricted by the inner wall of the cavity 130. After passing through the narrowest point of the cavity 130, the gas will split into multiple streams flowing in different directions. Therefore, regardless of whether the heating device 180 is located near the inlet 111 or the outlet 121 within the cavity 130, the heat generated by the heating device 180 can be absorbed by the cold air. The air is evenly discharged from the outlet 121, and the hourglass-shaped cavity 130 ensures that, regardless of the arrangement of the air inlet 111, the air velocity will be greatly increased when the air passes through the smallest cross-section of the cavity 130. This allows the fan blades of the fan 170 to be higher than the narrowest part of the cavity 130, which is beneficial for further increasing the velocity of the hot air. When the hot air flows out from the smallest cross-section of the cavity 130, the hot air will also become multiple branches of hot air flowing in different directions. The uniformity of heat distribution and flow velocity of the hot air flowing out from the outlet 121 will be greatly improved, thereby making the hot air more evenly applied to the cookware 20.

[0065] Please see Figure 4Based on the same inventive concept, in a second aspect, an embodiment of this application provides a cooking device 1, including a cooking utensil 10 and a pot 20 that cooperates with the cooking utensil 10. When the pot 20 is disposed on a mounting surface 120, at least a portion of the air outlet 121 has a gap between it and the outer wall of the pot 20. This allows hot air inside the cavity 130 to be smoothly discharged from the air outlet 121 and to continue cooking the pot 20.

[0066] In some embodiments, a partition 125 for placing the cookware 20 is further provided in the center of the mounting surface 120. An air outlet 121 is arranged around the partition 125. The diameter of the bottom surface of the cookware 20 is larger than the maximum width of the partition 125, and smaller than the maximum width of the air outlet 121. The partition 125 can be a metal plate. When the heating device 180 in the cavity 130 is operating, it transfers heat to the partition 125, and then to the cookware 20 through the partition 125. The partition 125 can also be a light-transmitting element. When the heating device 180 in the cavity 130 is operating, the heat it generates can be directly transferred to the cookware 20 through the light-transmitting plate via thermal radiation. Therefore, in order to maximize the heat generated by the heating device 180, the bottom diameter of the cookware 20 is larger than the maximum width of the partition 125 to obtain heat through heat conduction or thermal radiation via the partition 125.

[0067] Of course, by setting a gap between the cookware 20 and the air outlet 121, the bottom and side walls of the cookware 20 can both receive hot air supplementation, thereby improving the cooking efficiency and effect of the cookware 20.

[0068] In some embodiments, a guide 124 is provided at the edge of the mounting surface 120, surrounding the air outlet 121. When the cookware 20 is mounted on the mounting surface 120, there is a gap between the outer wall of the cookware 20 and the guide 124. By guiding the guide 124 toward the side wall of the mounting surface 120, the flow direction of hot air is changed, allowing the hot air to get as close as possible to the cookware 20 to supplement the cooking of the outer wall of the cookware 20.
