[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cooking device. Background Art

[0002] In the existing electromagnetic cooking appliances, during the working process, an alternating magnetic field is generated in the electromagnetic coil, and the magnetic field is conducted to the heating object through the electromagnetic coil to achieve cooking. The coil disk will generate heat due to its own resistance, and electronic components such as IGBT on the circuit board will also generate heat. If heat dissipation cannot be carried out in time, the temperature inside the cooking device will continue to rise, affecting the normal operation and service life of the cooking device.

[0003] In order to dissipate heat from the cooking device, an axial flow fan is usually arranged inside the cooking device. The axial flow fan sucks air from the bottom of the device and blows the sucked air along the vertical direction to the panel. Under the action of the wind pressure, the air moving to the panel then moves to the coil disk and the circuit board for heat dissipation. There is a problem that the air volume inside the cooking device is relatively small and the heat dissipation effect is not ideal.

[0004] Therefore, it is urgent to solve the technical problem that the air volume inside the cooking device is relatively small and the heat dissipation effect is not ideal. Content of the Utility Model

In addition, because the guide shell is integrally connected to the bottom shell, the guide shell and the bottom shell become an integrated part, eliminating the tedious assembly work of the guide shell, and can also improve the accuracy of the relative position of the guide shell and the bottom shell, thereby improving the production efficiency of the cooking device.

[0011] In a possible implementation, a plurality of air inlet holes are provided in the fan cover, and the air inlet holes are through holes, which not only allow airflow to pass through, but also prevent foreign objects such as insects from entering due to the smaller hole diameter, thereby avoiding affecting the normal operation of the cooking device.

[0013] In a possible implementation, the guide shell further includes a side baffle, which is integrally connected between the bottom shell and the first guide plate, and blocks the side of the air inlet cavity that is away from the heating zone. The side baffle can prevent the airflow introduced into the air inlet cavity by the fan from dispersing from the side of the air inlet cavity away from the heating zone, so that more airflow and stronger wind force are blown into the heating zone, thereby improving the heat dissipation efficiency of the heating element, effectively improving the timeliness of heat dissipation of the heating element, and preventing the heating element from overheating.

[0058] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0059] When the cooking device is working, the internal heating plate and the control board are prone to generate high temperatures. If the heat continues to accumulate and cannot be effectively dissipated, it will cause circuit aging and even safety accidents.

[0060] To accelerate heat dissipation, a heat sink is usually fixed on the top of the IGBT module provided on the top of the control board, and then in cooperation with a fan, the fan is used to accelerate the flow of air to dissipate heat for the IGBT module. In current cooking devices, the flow of air mainly uses wind pressure to blow the air introduced by the fan to the heating plate and the IGBT module. The air volume is relatively small, and the overall heat dissipation effect is poor, making it difficult to achieve high-power heating.

[0061] Therefore, the present utility model provides a cooking device. By providing a diversion housing, the diversion housing includes a first guiding plate, and the surface of the first guiding plate facing the air inlet chamber is a smoothly transitioning curved surface or inclined surface, such that the diversion housing serves to guide the airflow, thereby increasing the airflow wall attachment effect, changing the movement trajectory of the airflow, helping to guide more airflow to the heating element, improving the heat dissipation effect of the cooking device, and helping the cooking device to achieve high-power heating. In addition, since the diversion housing is integrally connected to the bottom case, the diversion housing and the bottom case become an integral part, eliminating the cumbersome assembly operation for the diversion housing, and also being able to improve the accuracy of the relative position between the diversion housing and the bottom case, and improving the production efficiency of the cooking device.

[0062] Reference Figure 1 、 Figure 2 and Figure 3 As shown in

[0063] the present utility model provides a cooking device, including: a bottom case 10 and a diversion housing 20. An accommodation cavity 11 is formed inside the bottom case 10, and a heating area 111 is provided inside the accommodation cavity 11, and a heating element is to be arranged inside the heating area 111.

[0064] The present utility model provides a cooking device. By providing a diversion housing 20, the diversion housing 20 includes a first guiding plate 22, and the surface of the first guiding plate 22 facing the air inlet chamber 21 is a smoothly transitioning curved surface or inclined surface, such that the diversion housing 20 serves to guide the airflow, thereby increasing the airflow wall attachment effect, changing the movement trajectory of the airflow, helping to guide more airflow to the heating element, improving the heat dissipation effect of the cooking device, and helping the cooking device to achieve high-power heating. In addition, since the diversion housing 20 is integrally connected to the bottom case 10, the diversion housing 20 and the bottom case 10 become an integral part, eliminating the cumbersome assembly operation for the diversion housing 20, and also being able to improve the accuracy of the relative position between the diversion housing 20 and the bottom case 10, and improving the production efficiency of the cooking device.

[0065] Under the action of the fan 30, the external air flow enters from the bottom of the air inlet cavity 21 and moves upward. Under the guiding action of the first guiding plate 22, after the air flow collides with the first guiding plate 22, it moves along the inner wall surface of the first guiding plate 22. Since the surface of the first guiding plate 22 facing the air inlet cavity 21 is a smoothly transitioning curved surface or inclined surface, the flow direction of the air flow is changed, and the air flow changes from moving vertically upward to moving towards the flow-through channel 24, which is beneficial for more air flow to move towards the heating element and improves the heat dissipation efficiency.

[0066] In this embodiment, the surface of the first guiding plate 22 facing the air inlet cavity 21 is a smoothly transitioning curved surface or inclined surface. Compared with the case where the surface of the first guiding plate 22 facing the air inlet cavity 21 has a sharp corner transition, such as a right-angle transition, the resistance of the air flow can be reduced, and the attenuation of the air flow velocity can be reduced, thereby helping to guide the air flow to the heating element and improving the heat dissipation effect of the cooking device.

[0067] The posture of the diversion shell 20 becomes a posture that guides the air flow entering the air inlet cavity 21, changes the movement direction, and then leaves the air inlet cavity 21 from the flow-through channel 24, improving the utilization rate of the air flow.

[0068] Under the action of the diversion shell 20, the air flow will flow along the inner surface of the diversion shell 20 during the flow. Since there is friction and viscous force between the air flow and the inner surface of the diversion shell 20, the flow velocity of the air flow near the inner surface of the diversion shell 20 slows down, while the air flow velocity far from the inner surface of the diversion shell 20 is faster. This velocity difference causes the air flow to be pulled towards the inner surface of the diversion shell 20 under the action of the viscous force, thereby changing the movement trajectory of the air flow, helping to guide the air flow to the heating element, improving the heat dissipation effect of the cooking device, and helping to achieve high-power cooking.

[0069] In a possible implementation manner, the surface of the first guiding plate 22 facing the air inlet cavity 21 is a smoothly transitioning curved surface, that is, the surface of the first guiding plate 22 facing the air inlet cavity 21 is a smooth arc surface, and the first guiding plate 22 can be an arc-shaped plate. The cross-section of the first guiding plate 22 cut along the transverse direction or the longitudinal direction is in an arc shape.

[0070] In a possible implementation manner, the surface of the first guide plate 22 facing the air inlet cavity 21 is a bevel with a smooth transition. For example, at least part of the surface of the first guide plate 22 facing the air inlet cavity 21 can be multiple bevels with a smooth transition connection. The multiple bevels can be sequentially connected along the edge of the air inlet cavity 21, so that the cross-sectional shape of at least part of the first guide plate 22 along the transverse direction is in a broken line shape, and the angle between two adjacent cross-sections is greater than 90°. In addition, the multiple bevels can also be sequentially connected along the axial direction of the fan 30, so that the cross-sectional shape of at least part of the first guide plate 22 along the longitudinal direction is in a broken line shape, and the angle between two adjacent cross-sections is greater than 90°.

[0071] In a possible implementation manner, the first guide plate 22 is located on the side of the air inlet cavity 21 away from the heat generating area 111. On the one hand, it can block the air flow from flowing out of the side of the air inlet cavity 21 away from the heat generating area 111. On the other hand, it can change the movement track of the air flow, so that more air flow enters the heat generating area 111 to dissipate heat for the heating element arranged in the heat generating area 111.

[0072] In a possible implementation manner, referring to Figure 4 、 Figure 5 and Figure 6 As shown, the bottom shell 10 includes a bottom shell main body 12 and a fan blade cover 14. An installation opening 121 is formed in the bottom shell main body 12. The fan blade cover 14 is detachably arranged in the installation opening 121, and the fan blade cover 14 is configured as the bottom wall of the air inlet cavity 21. This is because the size of the flow-through channel 24 is limited, and it is difficult to install and disassemble the fan 30 from the flow-through channel 24. Therefore, an installation opening 121 is formed in the bottom shell main body 12, and it is more convenient to install and disassemble the fan 30 through the installation opening 121, reducing the difficulty of assembling the fan 30.

[0073] In a possible implementation manner, the fan blade cover 14 can be connected to the installation opening 121 by means of screw connection or snap connection.

[0074] In a possible implementation manner, the shape of the installation opening 121 includes but is not limited to being circular, polygonal, etc., so that the fan 30 can be installed or disassembled through the installation opening 121.

[0075] In a possible implementation manner, the flow guide shell 20 and the bottom shell main body 12 can be an integrally injection-molded integral structure. There is no need to separately install the flow guide shell 20, and it can also avoid the problem of the flow guide shell 20 not being installed in place, simplifying the assembly process of the cooking device and helping to improve the assembly efficiency of the cooking device.

[0076] In a possible implementation manner, a plurality of air inlet holes 141 are formed in the fan blade cover 14, and the air inlet holes 141 are through holes. The air inlet holes 141 can be circular holes, oval holes, polygonal holes, waist-shaped holes, etc. The number of the air inlet holes 141 can be multiple and arranged at intervals, which can not only allow air flow to pass through, but also smaller hole diameters can prevent foreign objects such as insects in the outside world from entering, avoiding affecting the normal operation of the cooking device.

[0077] The fan blade cover 14 functions to protect the fan 30 and prevent dust, impurities, insects, etc. in the external environment from entering the fan 30.

[0078] In a possible implementation manner, the flow guide shell 20 further includes a second guide plate 23. The second guide plate 23 is connected to the first guide plate 22. The second guide plate 23 is located at the top of the air inlet cavity 21, and the surface of the second guide plate 23 facing the air inlet cavity 21 is a flat surface or an inclined surface.

[0079] The second guide plate 23 is connected to one end of the first guide plate 22 far from the bottom shell 10. The second guide plate 23 can prevent the air flow from diffusing upward in the air inlet cavity 21. The second guide plate 23 is beneficial to guiding the air flow toward the heating element in the heating area 111, so that more air flow enters the heating area 111.

[0080] In a possible implementation manner, the flow guide shell 20 further includes a side baffle 25. The side baffle 25 is integrally connected between the bottom shell 10 and the first guide plate 22, and the side baffle 25 shields the side of the air inlet cavity 21 facing away from the heating area 111.

[0081] The side baffle 25 can prevent the air flow introduced into the air inlet cavity 21 by the fan 30 from dispersing from the side of the air inlet cavity 21 away from the heating area 111, so that more air flow blows toward the heating area 111 and the wind force is stronger, improving the heat dissipation efficiency of the heating element, effectively improving the timeliness of heat dissipation of the heating element, and preventing the heating element from overheating.

[0082] In a possible implementation manner, the air inlet cavity 21 is a circular area, and the side baffle 25 can be arranged along the edge of the air inlet cavity 21. The side baffle 25 is integrally connected to the inner bottom wall of the bottom shell 10, which is beneficial to improving the stability of the fixed connection between the flow guide shell 20 and the bottom shell 10.

[0083] In a possible implementation, in order to improve the stability of the fixed connection between the flow guide housing 20 and the bottom housing 10, a reinforcing rib can be provided between the side facing away from the air inlet cavity 21 of the side baffle 25 and the inner bottom wall of the bottom housing 10. The reinforcing rib can be, for example, triangular or quadrilateral. Two adjacent sides of the reinforcing rib are respectively connected to the side facing away from the air inlet cavity 21 of the side baffle 25 and the inner bottom wall of the bottom housing 10, preventing the problem of insufficient self-supporting strength of the flow guide housing 20 caused by the relatively thin wall thickness of the flow guide housing 20, and improving the stability of the connection between the flow guide housing 20 and the bottom housing 10.

[0084] In a possible implementation, the number of the reinforcing ribs can be 1, 2, 3 or more. The multiple reinforcing ribs can be arranged at intervals along the edge of the side baffle 25, preventing the problem of the flow guide housing 20 shaking or even deforming, and ensuring the flow guiding effect of the flow guide housing 20.

[0085] In a possible implementation, referring to Figure 5 and Figure 6 as shown, the inner wall surface of the side baffle 25, the inner wall surface of the first guiding plate 22, and the inner wall surface of the second guiding plate 23 are smoothly transitioned, making the flow of the air along the inner wall surface of the flow guide housing 20 smoother. The inner wall surface of the flow guide housing 20 is the side facing the air inlet cavity 21 of the flow guide housing 20.

[0086] Referring to Figure 4 and Figure 5 the direction indicated by the dotted arrow in, the air flow introduced into the air inlet cavity 21 by the fan 30 moves upward. After the air flow collides with the first guiding plate 22, it moves along the inner wall surface of the first guiding plate 22 to the upper side of the air inlet cavity 21. Under the guiding action of the first guiding plate 22, the movement direction of the air flow changes, and then it moves along the second guiding plate 23 from the flow-through channel 24 to the heat generating area 111 to dissipate heat from the heat generating component arranged in the heat generating area 111.

[0087] In a possible implementation, referring to Figure 1 and Figure 3 as shown, the flow guide housing 20 further has a notch 26. The top of the fan 30 has a fixing frame 31. Two ends of the fixing frame 31 respectively extend into the notch 26, and at least part of the fixing frame 31 is blocked by the second guiding plate 23. Preventing the flow guide housing 20 from affecting the installation and fixation of the fan 30, the fixing frame 31 is used to fix the fan 30, and fixing holes 311 and positioning holes 312 are respectively opened at both ends of the fixing frame 31.

[0088] In a possible implementation manner, the inner bottom wall of the bottom case 10 is provided with fixing posts 15 and positioning posts 16. Both ends of the fixing bracket 31 are respectively abutted against the two fixing posts 15, and the positioning post 16 extends into the positioning hole 312. Fasteners such as screws or bolts are passed through the fixing hole 311 and the fixing post 15 to realize the connection between the fixing bracket 31 and the fixing post 15, so that the fan 30 is stably fixed in the air inlet cavity 21.

[0089] In a possible implementation manner, along the thickness direction of the cooking device, the projection of the diversion shell 20 coincides with the projection of at least half of the fan 30, which helps to ensure the effective diversion effect of the diversion shell 20, so that more air volume enters the heating area 111 to dissipate heat for the heating element. In this example, the fixing bracket 31 extends along the radial direction of the fan 30, and one end of the second guiding plate 23 away from the first guiding plate 22 is located above the fixing bracket 31.

[0090] In a possible implementation manner, there is a gap between the second guiding plate 23 and the fan 30, and the gap between the second guiding plate 23 and the fan 30 is configured as an air flow passage 24. The air flow passage 24 becomes the passage for the air flow in the air inlet cavity 21 to flow into the heating area 111.

[0091] In a possible implementation manner, referring to Figure 2 and Figure 3 As shown, the bottom case 10 further includes a wind blocking rib 13. The wind blocking rib 13 is connected to the bottom wall of the accommodating cavity 11. The wind blocking rib 13 blocks between the air inlet cavity 21 and the heating area 111, which helps the air flow to pass through the upper surface of the heating element, improves the utilization rate of the air flow, and improves the heat dissipation effect.

[0092] In a possible implementation manner, referring to Figure 1 and Figure 2 As shown, the cooking device provided by the present utility model further includes a heating element disposed in the heating area 111. The heating element includes a heating plate 40 and a control board 50. The air flow passage 24 faces the heating element, so that the cold air blown out from the air flow passage 24 blows directly against the heating element, thereby effectively ensuring the heat dissipation effect on the heating element.

[0093] The control board 50 is a printed circuit board (Printed Circuit Board, abbreviated as PCB). An insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, abbreviated as IGBT) module is installed on the control board 50. Since the IGBT module 51 is prone to overheat and damage when the cooking device is in use, in this application, by guiding the cold air to the control board 50, it helps to dissipate heat and cool down the IGBT module 51, ensures the normal operation of the IGBT module 51, and prevents the problem that the control board 50 is damaged due to excessive temperature.

[0094] In a possible implementation, the fan 30 is an axial flow fan. The axial flow fan has the advantages of large air volume and small volume, and can save the space occupied in the accommodation cavity 11. The axial flow fan makes a large amount of air move along the same direction as the fan axis, enabling more air flow to enter the air inlet cavity 21, which helps to improve the heat dissipation efficiency of the cooking device.

[0095] A plurality of feet are connected to the bottom of the bottom shell 10, for example, 4 feet, and the 4 feet are respectively connected to the 4 corner positions of the bottom shell 10 to improve the stability of the placement of the cooking device. In addition, the feet also keep a certain distance between the bottom shell 10 of the cooking device and the tabletop on which the cooking device is placed, which is beneficial for air flow to enter the air inlet cavity 21 through the air inlet holes 141 opened in the fan blade cover 14 on the bottom surface of the bottom shell 10. A plurality of heat dissipation holes 17 are opened on the side wall of the bottom shell 10, and the air flow taking away the heat of the heating element flows out of the cooking device through the heat dissipation holes 17 to realize heat dissipation for the cooking device.

[0096] A cooking device provided by the present utility model includes, but is not limited to, an induction cooker, and may also be other electromagnetic heating devices, etc.

[0097] In the case where a cooking device provided by an embodiment of the present utility model is an induction cooker, the heating plate 40 is a coil disc, and the heating plate 40 includes a coil disc frame 41 and a coil 42. The coil 42 is wound and arranged on the upper surface of the coil disc frame 41. Specifically, a plurality of wiring grooves are provided on the upper surface of the coil disc frame 41, and the coil 42 is arranged in the wiring grooves.

[0098] In a possible implementation, referring to Figure 5 and Figure 6 as shown, the cooking device further includes an upper cover 60. The upper cover 60 is buckled with the bottom shell 10, and a panel 70 is provided at the top end of the upper cover 60. The panel 70 includes, but is not limited to, a heat-resistant ceramic or a glass-ceramic panel 70.

[0099] During cooking, a cooking container such as a pot is placed on the panel 70, and an alternating current is passed through the heating plate 40 to generate an alternating magnetic field. The magnetic force lines of the alternating magnetic field pass through the bottom of the metal pot, generating a large amount of eddy currents at the bottom of the pot, thereby generating the heat required for cooking.

[0100] Referring to Figure 1 and Figure 5As shown in the figure, the cooking device further includes a lamp panel disposed in the accommodation cavity 11 and a temperature measuring element disposed at the center of the heating plate 40. Among them, the fan 30, the heating plate 40, the lamp panel, and the temperature measuring element are all electrically connected to the control board 50. The heating plate 40 heats cookware and the like placed on the cooking device. The control board 50 adjusts the power of the heating plate 40 according to the temperature detected by the temperature measuring element. The fan 30 is used to accelerate the convection speed of the air in the accommodation cavity 11 and the outside air, playing a role in heat dissipation and temperature reduction. The lamp panel can be provided with control devices such as buttons and indicator lights and / or display devices. The upper cover 60 has an operation area corresponding to the lamp panel, facilitating the user to perform control operations.

[0101] For a cooking device provided by the present utility model, the air flow trajectory can be changed through the diversion shell 20, enabling more air flow to enter the heating area 111 to dissipate heat for the heating element, improving the heat dissipation effect, reducing the temperature rise of the heating element, and enabling long-term high-fire heating.

[0102] For a cooking device provided by the present utility model, since the diversion shell 20 is integrally connected to the bottom shell 10, there is no need to separately produce, transport, and assemble the diversion shell 20, simplifying the production and assembly operations. It can also improve the accuracy of the relative position between the diversion shell 20 and the bottom shell 10, improving the production efficiency of the cooking device and helping to save costs.

[0103] For a cooking device provided by the present utility model, different from the prior art where the cold air is made to flow to the heating area by wind pressure, under the guiding action of the diversion shell 20, the wall attachment effect of the air flow is utilized to change the movement trajectory of the air flow. Therefore, the problem of insufficient wind pressure affecting the heat dissipation effect can be solved, and more air flow can be guided into the heating area to dissipate heat for the heating element, thereby improving the heat dissipation effect of the cooking device.
