Description

Technical Field

[0001] The present invention relates to the technical field of cooking utensils, and in particular to a cooking utensil. Background Art

[0002] Existing cooking appliances, such as steam-bake combination machines, are usually equipped with a fan and a heating tube on the inner pot. Under the action of the fan, a circulating airflow is formed in the inner pot, and the circulating airflow contacts the heating tube and heats up. The high-temperature airflow gradually increases the temperature in the inner pot, thereby heating the food in the inner pot.

[0003] Some steam ovens are equipped with two fans, which are respectively installed in different positions. Each of the two fans is provided with a heating pipe to heat the air discharged by the fan.

[0004] However, the structure of the heating tube and its circuit connection are more complicated and the cost is higher. Summary of the invention

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a cooking utensil is provided, which includes: an inner pot, the inner pot having a mounting wall; a fan assembly, the fan assembly including a first fan and a second fan arranged on the mounting wall, the first fan having a first air outlet area, and the second fan having a second air outlet area; a heating element, the heating element is arranged on the mounting wall, the heating element has a heating area, the heating area has at least a partial structural overlap with the first air outlet area, and the heating area has at least a partial structural overlap with the second air outlet area.

[0006] The cooking utensil provided by the present invention has a first fan and a second fan, so that the air flow efficiency formed in the inner pot is faster, the temperature field in each part of the inner pot is more uniform, and the cooking effect is better. The air outlet of the first fan and the second fan is heated and heated by the same heating element to form a high-temperature airflow flowing to the inner pot, and the cooking effect can be guaranteed. Compared with the scheme in which the heating tube and the fan are set one by one in the prior art, the cooking utensil provided by the present invention has a heating element that can heat and heat the air outlet of the first fan and the second fan at the same time, and the structural setting is simpler, and the circuit connection involved is also simpler, and the production difficulty and cost are lower.

[0007] For example, the heating element forms an enclosed area, the projection of the first fan toward the plane where the heating element is located is located in the enclosed area, and the projection of the second fan toward the plane where the heating element is located is located in the enclosed area. In this way, the space occupied by the heating element can be smaller, even if the space in the inner pot that can be used for cooking food is larger, the structural setting is more reasonable.

[0008] Exemplarily, the heating element has a first arc segment and a second arc segment, the first arc segment is arranged around the first fan, and the second arc segment is arranged around the second fan. In this way, the first arc segment and the second arc segment can heat the air outlet of the first fan and the air outlet of the second fan respectively, the distance between the wind and the heating element is closer, and the heating efficiency is higher.

[0009] Exemplarily, the first arc segment has a first end and a second end facing the second arc segment, the second arc segment has a third end and a fourth end facing the first arc segment, a connecting segment is provided between the first end and the third end, the second end is connected to a first mounting segment connected to the mounting wall, and the fourth end is connected to a second mounting segment connected to the mounting wall. The first mounting segment and the second mounting segment are connected to the mounting wall to ensure the stability of the connection between the heating element as a whole and the mounting wall. The overall structure of the heating element is simpler and the production cost is lower.

[0010] Exemplarily, a mounting bracket is provided on the mounting wall, and the mounting bracket is multiple and is mounted on one or more of the first end, the second end, the third end, the fourth end, the middle of the first arc segment, and the middle of the second arc segment. In this way, the heating element is further better fixed on the mounting wall.

[0011] Exemplarily, a cover plate is provided on the side of the mounting wall facing the interior of the inner pot, the heating element is located between the cover plate and the mounting wall, and a first air outlet hole and a second air outlet hole are provided on the cover plate, the first air outlet hole is located in the first air outlet area, and the second air outlet hole is located in the second air outlet area. The setting of the cover plate can prevent the first fan and the second fan from being directly exposed to the inner pot, thereby preventing users from being scalded. The air outlet of the first fan and the second fan enters the gap between the cover plate and the mounting wall, and the gap can increase the residence time of the air to a certain extent, so that the heating element has a better heating effect on the air outlet. The setting of the first air outlet hole and the second air outlet hole makes the air outlet position more controllable, and the heating efficiency of the cooking appliance can be improved by the reasonable setting of the first air outlet hole and the second air outlet hole.

[0012] For example, the cover plate is further provided with a first air inlet hole and a second air inlet hole, the first air inlet hole is aligned with the first air inlet area of ​​the first fan, and the second air inlet hole is aligned with the second air inlet area of ​​the second fan. This arrangement makes the air inlet and air outlet process of the first fan and the second fan smoother, thereby ensuring the cooking efficiency of the cooking appliance.

[0013] Exemplarily, the first fan and / or the second fan are axial air inlet and radial air outlet fans. The air outlet area of ​​the first fan and / or the second fan is located at its periphery, the air outlet is more dispersed, the temperature field inside the inner pot is more balanced, and the cooking effect is better.

[0014] Exemplarily, the first air outlet and the second air outlet are arranged at opposite ends of the cover plate at intervals along a predetermined direction, so that the temperature field inside the inner pot is further balanced and the cooking effect is better.

[0015] Exemplarily, a third air outlet is also provided on the cover plate, and at least part of the structure of the third air outlet is located in the first air outlet area and at least part of the structure of the third air outlet is located in the second air outlet area. In this way, the air from the first fan and the second fan can better enter the interior of the inner tank, and the heating efficiency is higher.

[0016] For example, the projection of the third air outlet on a predetermined plane parallel to the mounting wall overlaps with the projection of the heating element on the predetermined plane. In this way, the third air outlet can discharge air on the one hand, and the heat of the heating element can partially flow out from the third air outlet through irradiation on the other hand, further improving the heating efficiency of the cooking appliance.

[0017] Exemplarily, a cover plate is provided on the side of the mounting wall facing the inside of the inner pot, the first fan includes a first impeller, a first output shaft and a first motor body, the first impeller is connected to the first motor body through the first output shaft, the second fan includes a second impeller, a second output shaft and a second motor body, the second impeller is connected to the second motor body through the second output shaft, the first impeller and the second impeller are located between the mounting wall and the cover plate, and the first motor and the second motor are arranged on the side of the mounting wall facing the outside. The rotation speed and rotation direction of the first fan and the second fan are completely independent. In this way, the air outlet effects of the first fan and the second fan can be controlled separately, and the cooking effect of the cooking appliance can be better controlled.

[0018] Exemplarily, the first impeller and the second impeller rotate in opposite directions. In this way, the air outlets of the first fan and the second fan are more dispersed, so that the temperature field inside the inner pot is more balanced and the cooking effect is better.

[0019] A series of simplified concepts are introduced in the summary of the invention, which will be further described in detail in the detailed description.

[0039] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0040] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0041] In an embodiment of the present invention, a cooking appliance is provided. The cooking appliance may be any type of cooking appliance such as a steam-bake combination machine, a steamer, an oven, an air fryer, etc. Figure 1 , 45. The cooking utensil includes an inner pot 10, a fan assembly 20 and a heating element 30. The inner pot 10 has a mounting wall 110, and the mounting wall 110 can be any side wall of the inner pot 10, such as a top wall, a rear side wall, etc. The fan assembly 20 can include a first fan 210 and a second fan 220 arranged on the mounting wall 110. The first fan 210 has a first air outlet area, and the second fan 220 has a second air outlet area. Among them, the first air outlet area can be understood as the area that the air outlet of the first fan 210 can cover, and the second air outlet area can be understood as the area that the air outlet of the second fan 220 can cover. The air outlet area is related to factors such as the type and power of the fan. For example, when the fan is radially outgoing, the air outlet area is the peripheral part of the fan. The heating element 30 can be arranged on the mounting wall 110, and the heating element 30 has a heating area. Among them, the heating area can be understood as the area where the heating element 30 can play a heating and temperature raising role. The heating area of ​​the heating element is related to factors such as its type and power. The heating element 30 may be a heating tube. Exemplarily, the heating element 30 may be a far-infrared heating tube, which has a higher heating efficiency. The heating area may have at least a partial structural overlap with the first air outlet area, and the heating area may have at least a partial structural overlap with the second air outlet area. In other words, the first fan 210 and the second fan 220 may share the same heating element 30. The heating element 30 heats and heats the air outlets of the first fan 210 and the second fan 220 at the same time. Taking the first fan 210 as an example, the first fan 210 works and discharges air, and the wind enters the first air outlet area, wherein at least part of the wind passes through the heating and temperature raising effect of the heating area to form a high-temperature airflow, and the high-temperature airflow flows into the inner liner 10, and the temperature in the inner liner 10 gradually rises and the food in the inner liner 10 is heated and cooked.

[0042] The cooking utensil provided by the present invention is provided with the first fan 210 and the second fan 220, so that the air flow efficiency formed in the inner pot 10 is faster, the temperature field in each part of the inner pot 10 is more uniform, and the cooking effect is better. The air outlet of the first fan 210 and the second fan 220 is heated and heated by the same heating element 30 to form a high-temperature airflow flowing to the inner pot 10, and the cooking effect can be guaranteed. Compared with the scheme in which the heating tube and the fan are arranged one by one in the prior art, the cooking utensil provided by the present invention, the heating element 30 can heat and heat the air outlet of the first fan 210 and the second fan 220 at the same time, the structural arrangement is simpler, the circuit connection involved is also simpler, and the production difficulty and cost are lower.

[0043] For example, refer to Figure 4 and 11, the heating element 30 can form an enclosed area 301. The projection of the first fan 210 toward the plane where the heating element 30 is located can be located in the enclosed area 301, and the projection of the second fan 220 toward the plane where the heating element 30 is located can be located in the enclosed area 301. In other words, the heating element 30 can surround the first fan 210 and the second fan 220. The heating element 30 can be located at the periphery of the first fan 210 and the second fan 220. In the direction perpendicular to the mounting wall 110, the heating element 30 can have an overlapping portion with the first fan 210 and / or the second fan 220 to avoid the heating element 30 occupying too much space. With this arrangement, the space occupied by the heating element 30 can be smaller, even if the space available for cooking food in the inner pot 10 is larger, the structural arrangement is more reasonable. It can be understood that the enclosed area 301 can be understood as the area enclosed by the heating element 30 entity. In some embodiments, the projection of the first fan and / or the second fan toward the plane where the heating element is located may be located outside the enclosed area, and may be staggered with the heating element in a direction perpendicular to the installation wall.

[0044] For example, continue to refer to Figure 4 and 11 , the heating element 30 may have a first arc segment 310 and a second arc segment 320. The first arc segment 310 is arranged around the first fan 210, and the second arc segment 320 is arranged around the second fan 220. In this way, the first arc segment 310 and the second arc segment 320 can heat and raise the temperature of the outlet air of the first fan 210 and the outlet air of the second fan 220 respectively, and the distance between the wind and the heating element 30 is closer, and the heating efficiency is higher. In an embodiment in which the projection of the first fan 210 and the second fan 220 toward the plane where the heating element 30 is located is located within the enclosed area, the heating element 30 surrounds the outer ring of the first fan 210 and the second fan 220. Exemplarily, the first arc segment 310 may be an arc, the center of the arc coincides with the rotation axis of the first fan 210, and the radius of the arc is greater than the radius of the first fan 210. The second arc segment 320 may be an arc-shaped structure, the center of the arc-shaped structure coincides with the rotation axis of the second fan 220, and the radius of the arc is greater than the radius of the second fan 220. Of course, the shape of the heating element 30 may be any other setting according to the use requirements. For example, the heating element may be a roughly rectangular ring structure, and the first fan and the second fan are located in the rectangular ring structure.

[0045] For example, in conjunction with reference Fig.11 and 13, the first arc segment 310 may have a first end 3101 and a second end 3102 facing the second arc segment 320. The second arc segment 320 may have a third end 3201 and a fourth end 3202 facing the first arc segment 310. A connecting section 330 may be provided between the first end 3101 and the third end 3201. The second end 3102 may be connected to a first mounting section 340 connected to the mounting wall 110, and the fourth end 3202 may be connected to a second mounting section 350 connected to the mounting wall 110. The first mounting section 340 may be located below the first fan 210, and the second mounting section 350 may be located below the second fan 220. The connecting section 330 is arranged opposite to the first mounting section 340 and the second mounting section 350, and is located above the first fan 210 and the second fan 220. The first mounting section 340 and the second mounting section 350 are connected to the mounting wall 110 to ensure the stability of the connection between the heating element 30 as a whole and the mounting wall 110. The first installation section 340, the first arc section 310, the connection section 330, the second arc section 320, and the second installation section 350 are connected in sequence, and the overall structure of the heating element 30 is simpler and the production cost is lower. The heating element 30 can be roughly in a runway-shaped structure, with a larger heating and irradiation area and better thermal efficiency. For example, in combination with reference Figure 13-15 The first mounting section 340 and the second mounting section 350 may have a bent structure bent toward the mounting wall 110. The circuit connection structure of the heating element 30, such as the wiring terminal, is located on the first mounting section 340 and the second mounting section 350. Since the air outlet of the first fan 210 and the second fan 220 is heated by the same heating element 30, the wiring terminal structure involved in the heating element 30 can be simpler in structure and circuit setting compared with the technical solution of multiple heating tubes.

[0046] For example, in conjunction with reference Figure 11-13 , a mounting frame 120 may be provided on the mounting wall 110, and the mounting frame 120 may be multiple and may be installed on one or more of the first end 3101, the second end 3102, the third end 3201, the fourth end 3202, the middle of the first arc segment 310, and the middle of the second arc segment 320. In this way, the heating element 30 is further better fixed on the mounting wall 110. Of course, the mounting frame may be provided at any other position. Furthermore, in an embodiment in which a cover plate 40 is provided, the cover plate 40 may be mounted to the mounting wall 110 by a cover plate mounting frame 130. The cover plate mounting frame 130 may be provided integrally with a portion of the mounting frame 120.

[0047] For example, in conjunction with reference Figure 1-5, a cover plate 40 may be provided on the side of the mounting wall 110 facing the inside of the inner pot 10, the heating element 30 is located between the cover plate 40 and the mounting wall 110, and a first air outlet hole 410 and a second air outlet hole 420 are provided on the cover plate 40, the first air outlet hole 410 is located in the first air outlet area, and the second air outlet hole 420 is located in the second air outlet area. The setting of the cover plate 40 can prevent the first fan 210 and the second fan 220 from being directly exposed to the inner pot 10, thereby preventing users from being scalded. The air outlet of the first fan 210 and the second fan 220 enters the gap between the cover plate 40 and the mounting wall 110, and the gap can increase the residence time of the air to a certain extent, and the heating element 30 has a better heating effect on the air outlet. The setting of the first air outlet hole 410 and the second air outlet hole 420 makes the air outlet position more controllable, and the heating efficiency of the cooking appliance can be improved by the reasonable setting of the first air outlet hole 410 and the second air outlet hole 420.

[0048] Exemplarily, the cover plate 40 is further provided with a first air inlet hole 440 and a second air inlet hole 450, wherein the first air inlet hole 440 is aligned with the first air inlet area of ​​the first fan 210, and the second air inlet hole 450 is aligned with the second air inlet area of ​​the second fan 220. The first air inlet area is the area through which the wind entering the first fan 210 needs to flow. In the embodiment in which the first fan 210 is axially inlet and radially outlet, the first air inlet area is the area within a certain range near the rotation axis of the first fan 210. The second air inlet area is the same. The air discharged by the first fan 210 enters the first air outlet area, is heated by the heating element 30, and enters the cooking space of the inner pot 10 through the first air outlet hole 410. The food in the cooking space is cooked, and enters the corresponding air inlet area through the first air inlet hole 440 and / or the second air inlet hole 450, and the cycle repeats. The air discharge of the second fan 220 is the same. This arrangement makes the air intake and air discharge process of the first fan 210 and the second fan 220 smoother, so as to ensure the cooking efficiency of the cooking appliance. Exemplarily, the first air intake area is correspondingly provided with a first air intake panel, the first air intake panel can be in a disc shape, and the first air intake holes 440 are arranged on the first air intake panel. The second air intake area is correspondingly provided with a second air intake panel, the second air intake panel can be in a disc shape, and the second air intake holes 450 are arranged on the second air intake panel.

[0049] For example, the first fan 210 and / or the second fan 220 may be axial air inlet and radial air outlet fans. The air outlet area of ​​the first fan 210 and / or the second fan 220 is located at its periphery, the air outlet is more dispersed, the temperature field inside the inner pot 10 is more balanced, and the cooking effect is better.

[0050] For example, in conjunction with reference Figure 6 and 11, the first air outlet 410 and the second air outlet 420 are arranged at opposite ends of the cover plate 40 at intervals along the predetermined direction AA. In this way, the temperature field inside the inner pot 10 is further balanced, and the cooking effect is better. Among them, there can be multiple first air outlets 410, and a part of the multiple first air outlets 410 can be located above the first fan 210 and another part can be located below the first fan 210. There can be multiple second air outlets 420, and a part of the multiple second air outlets 420 can be located above the second fan 220 and another part can be located below the second fan 220. In other words, the air outlets can be distributed at the four corners of the cover plate 40, and the distribution is more uniform. The heating element can be located between the fan and the corresponding air outlet to ensure that the wind flowing out of the air outlet is fully heated and has a higher temperature. Exemplarily, the first fan 210 and the second fan 220 can be arranged at intervals along the predetermined direction AA. The predetermined direction AA may be the length direction of the inner liner 10 as in the illustrated embodiment, and may also be the width direction of the inner liner, or a diagonal direction, etc. in some embodiments.

[0051] For example, in conjunction with reference Figure 8 and 11 The cover plate 40 is also provided with a third air outlet 430, at least part of the structure of the third air outlet 430 is located in the first air outlet area and at least part of the structure of the third air outlet 430 is located in the second air outlet area. The third air outlet 430 can be extended in a long strip shape. The third air outlet 430 can be located between the first fan 210 and the second fan 220. In this way, the air from the first fan 210 and the second fan 220 can better enter the interior of the inner liner 10, and the heating efficiency is higher.

[0052] For example, continue to combine with reference Figure 8 and 11 , the projection of the third air outlet 430 on the predetermined plane parallel to the installation wall 110 and the projection of the heating element 30 on the predetermined plane have an overlapping portion. In this way, the third air outlet 430 can discharge air on the one hand, and on the other hand, the heat of the heating element 30 can partially flow out from the third air outlet 430 through irradiation, further improving the heating efficiency of the cooking appliance. Exemplarily, the connecting section 330 can extend along a predetermined direction, and accordingly, the third air outlet 430 can be a long strip through hole extending along the predetermined direction AA.

[0053] For example, in conjunction with reference Figure 5 and 7, a cover plate 40 is provided on one side of the mounting wall 110 facing the inside of the inner pot 10. The first fan 210 may include a first impeller 2101, a first output shaft 2102 and a first motor body 2103. The first impeller 2101 is connected to the first motor body 2103 through the first output shaft 2102. The second fan 220 may include a second impeller, a second output shaft and a second motor body. The second impeller is connected to the second motor body through the second output shaft. The first impeller 2101 and the second impeller may be located between the mounting wall 110 and the cover plate 40, and the first motor body 2103 and the second motor body are arranged on the side of the mounting wall 110 facing the outside. The rotation speed and rotation direction of the first fan 210 and the second fan 220 are completely independent. In this way, the air outlet effects of the first fan 210 and the second fan 220 can be controlled respectively, and the cooking effect of the cooking utensil can be better controlled. In some embodiments, the first fan and the second fan may be connected to the same motor.

[0054] For example, the first impeller 2101 and the second impeller rotate in opposite directions. In this way, the air output of the first fan 210 and the second fan 220 is more dispersed, so that the temperature field inside the inner pot 10 is more balanced and the cooking effect is better. Fig.11 Taking the illustrated embodiment as an example, the first fan 210 can rotate in a counterclockwise direction, and the second fan 220 can rotate in a clockwise direction, so that the air can better contact with the heating element 30 and heat up, thereby further ensuring the cooking effect.
