Description

Technical Field

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

[0002] In the related art, the cooking appliance includes an axial flow motor, a fan and a cooking body. The axial flow motor and the fan are both located on the top of the cooking body. The fume extraction flow path of the cooking appliance is not set reasonably, and the fume extraction effect is poor. In order to achieve a better air suction effect, the rotation speed of the first axial flow fan is increased, which results in a very loud operating noise of the cooking appliance, reducing the performance of the product. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, one aspect of the present application provides a cooking appliance.

[0005] In view of this, one aspect of the present application proposes a cooking appliance, comprising: an outer shell, the outer shell being provided with an air inlet and an air outlet; a stove plate, located in the outer shell, the stove plate being provided with a first opening; a cooking body, located in the outer shell, the cooking body being provided with a cooking cavity, the air inlet being located at the bottom of the cooking body, the stove plate being located between the top of the cooking body and the air outlet, the stove plate and the cooking body enclose a flow cavity, the outer shell and the cooking body enclose an oil fume duct, the oil fume duct extends from the air inlet along the side of the cooking body to the flow cavity; a first fan, located at the first opening, the first fan comprising a wind wheel, the inner circumference of the wind wheel encloses an inlet and outlet portion, the outer circumference of the wind wheel being provided with an outlet portion, the inlet portion being connected to the flow cavity, the first opening connecting the outlet portion and the air outlet, the first fan being used to drive the airflow from the oil fume duct into the inlet portion, and flowing to the air outlet through the outlet portion.

[0006] A cooking appliance provided in the present application includes a shell, a stove plate, a cooking body and a first fan.

[0007] The stove plate, the cooking body and the first fan are all arranged in the shell, and the shell serves as a mounting carrier for the stove plate, the cooking body and the first fan, and has the function of mounting and fixing the stove plate, the cooking body and the first fan, and the shell can protect the stove plate, the cooking body and the first fan. It can be understood that the shell forms the appearance of the cooking utensil.

[0008] The cooking body is provided with a cooking cavity, and ingredients can be placed in the cooking cavity and cooked in the cooking cavity to meet usage needs such as heating ingredients, baking ingredients, and micro-steaming and baking ingredients.

[0009] The outer shell is provided with an air inlet and an air outlet. The stove plate is located between the top of the cooking body and the air outlet, and the stove plate and the cooking body enclose a flow cavity. The oil fume duct connects the air inlet and the flow cavity. The outer shell and the cooking body enclose an oil fume duct, and the oil fume duct extends from the air inlet along the side of the cooking body to the flow cavity. That is, the oil fume duct connects the air inlet and the flow cavity. The first fan is arranged on the side of the stove plate away from the cooking body, and the first fan includes a wind wheel, the inner circumference of the wind wheel encloses the inlet and outlet, and the outer circumference of the wind wheel is provided with an outlet. The inlet is connected to the flow cavity, and the outlet is connected to the air outlet through the first opening of the stove plate.

[0010] The air inlet is located at the bottom of the cooking body. When the cooking utensil is placed on the stove, the operation of the first fan can drive the wind wheel to work. The rotation of the wind wheel drives the air flow from the air inlet into the oil fume duct, through the oil fume duct into the flow cavity, and then through the flow cavity to the inlet, and then through the outlet and the first opening to the air outlet, and finally discharged from the cooking utensil through the air outlet. In other words, when the cooking utensil is working, the air inlet draws air from the stove, so as to draw the water mist, smoke, etc. generated by cooking on the stove into the oil fume duct and the flow cavity, and then discharge them from the air outlet after filtering. This setting allows the gas to be discharged in a directional manner. For example, the air outlet can be set toward the window, or in a direction away from the crowd, so as to avoid the spread of water mist and oil fume in the room, thereby preventing oil stains from adhering to furniture or oil fume and odors from adhering to clothes, thereby reducing the impact on the indoor environment.

[0011] Furthermore, the air inlet is located at the bottom of the cooking body, that is, the air inlet is located at a position relatively close to the stove. In addition, the stove plate is located between the top of the cooking body and the air outlet, and the stove plate and the cooking body enclose a flow cavity, and the inlet of the first fan is connected to the flow cavity. In other words, the flow cavity connects the oil fume duct and the inlet of the first fan, and the space of the flow cavity is relatively large, and the resistance to the airflow is relatively small. In this way, more gas can flow from the air inlet to the air outlet, which is conducive to reducing the attenuation of the air volume, so that the water mist, smoke, etc. at the stove can be sucked into the cooking utensil in time, and the working efficiency of the first fan is enhanced. It can be understood that under the condition of the same oil fume absorption effect, the speed of the motor can be reduced, so that the operating noise of the cooking utensil during operation can be reduced, which is conducive to improving the product's performance and market competitiveness. At the same time, this setting allows the smoke at the stove to be effectively sucked into the oil fume duct, which can reduce the oil fume concentration and surrounding temperature around the cook, and concentrate the oil fume and hot air at the air outlet, thereby greatly improving the heat and smoke exhaust efficiency of the cooking utensils.

[0012] The cooking utensil described above in this application may also have the following additional technical features:

[0013] In some embodiments, optionally, the oil fume duct extends to the flow cavity through a side portion of the cooking body.

[0014] In this embodiment, the matching structure between the oil fume air duct and the cooking body is further defined.

[0015] The oil fume duct extends to the flow cavity through one side of the cooking body. That is, when the first fan is working, the driving airflow enters the oil fume duct from the air inlet, flows to the flow cavity through the oil fume duct on one side of the cooking body, then flows to the inlet of the first fan through the flow cavity, then flows to the air outlet through the outlet, and finally is discharged from the cooking utensil through the air outlet, so that water mist, smoke, etc. are effectively guided to the air outlet.

[0016] In some embodiments, optionally, the oil fume duct extends to the flow cavity through the side portions of at least two sides of the cooking body.

[0017] In this embodiment, the matching structure between the oil fume air duct and the cooking body is further defined.

[0018] The oil fume duct extends to the flow cavity through the side parts of at least two sides of the cooking body. For example, the oil fume duct includes a plurality of oil fume segments, each of which is located on one side of the cooking body, and each of which is connected to the air inlet and the flow cavity. This arrangement enables the airflow to converge to the flow cavity from multiple directions and multiple angles when the first fan is working, thereby increasing the flow rate of the airflow, which is beneficial to increasing the air suction capacity of the cooking appliance and improving the oil fume extraction effect of the cooking appliance.

[0019] In some embodiments, optionally, the axis of the wind wheel is arranged opposite to the middle of the furnace plate.

[0020] In this embodiment, the matching structure between the wind wheel and the furnace plate is further defined.

[0021] The axis of the wind wheel is arranged opposite to the middle of the furnace plate.

[0022] Specifically, the oil fume duct extends to the flow chamber through the side parts of at least two sides of the cooking body, and the axis of the wind wheel is arranged opposite to the middle part of the stove plate. That is, the wind wheel is installed in the middle part of the stove plate. This arrangement facilitates the reasonable layout of other components of the cooking appliance, and the position of the wind wheel is matched with the position of the oil fume duct, which can ensure the balance and consistency of the oil fume suction when the first fan is working, so that the water mist, oil fume, etc. at different positions of the stove can be effectively sucked into the cooking appliance, which can ensure the oil fume extraction effect of the cooking appliance.

[0023] In some embodiments, optionally, the outer diameter of the wind wheel is recorded as D1; ​​the width of the stove plate from the face of the cooking utensil to the back of the cooking utensil is recorded as D2;

[0024] Among them, 3 / 7≤D1 / D2≤6 / 7.

[0025] In this embodiment, the structure of the cooking appliance is further defined.

[0026] The outer diameter of the wind wheel is D1. The width of the stove plate from the front to the back of the cooking utensil is D2. The relationship between D1 and D2 satisfies: 3 / 7≤D1 / D2≤6 / 7.

[0027] That is to say, the matching size of the fan wheel and the stove plate is limited. This setting reasonably utilizes the installation space between the stove plate, the shell and the cooking body, and increases the outer size of the fan wheel. In this way, when the speed of the first fan is constant, the fume extraction effect of the first fan can be increased. That is to say, while ensuring the fume extraction effect of the cooking appliance, it is conducive to further reducing the speed of the first fan, thereby further reducing the operating noise of the cooking appliance when it is working.

[0028] In some embodiments, optionally, the furnace plate is provided with a volute, the inner circumferential surface of the volute forms a first opening, the volute is provided with a second opening, and the second opening is connected to the first opening and the air outlet.

[0029] In this embodiment, the structure of the cooking appliance is further defined.

[0030] The furnace plate is provided with a volute, the inner circumference of the volute forms a first opening, and the wind wheel is arranged at the first opening of the volute. That is, the volute serves as a mounting carrier of the wind wheel, has the function of mounting and fixing the wind wheel, can ensure the matching size of the wind wheel and the first opening, and provides structural support for the airflow to flow from the air inlet to the air outlet under the action of the wind wheel. The airflow flows into the outlet through the inlet, then flows into the first opening through the outlet, then flows into the second opening through the first opening, and finally flows to the air outlet.

[0031] It can be understood that the inner surface of the volute has the function of limiting the flow path of the gas, so that the gas is directed to the air outlet, thereby preventing the oil smoke from flowing to other positions of the cooking appliance.

[0032] The volute has the function of expanding pressure. The velocity of the airflow flowing into the air inlet is relatively high. The volute with a uniformly increased flow area reduces the deflection of the airflow and reduces the flow loss of the airflow, so that more energy is converted into static pressure, thereby increasing the air volume and avoiding the situation where the flow loss of the airflow is large due to excessive velocity, the aerodynamic performance is poor, and the air volume is reduced. At the same time, the volute has the function of collecting flow, reducing the frequency of airflow separation, de-flow, vortex and other phenomena, which is conducive to further reducing the operating noise of the cooking appliance and improving the fume extraction effect of the cooking appliance.

[0033] In some embodiments, optionally, a side of the stove plate facing away from the cooking body is further provided with a surrounding plate, and the surrounding plate, the first part of the outer peripheral surface of the volute and the stove plate enclose an air guide groove, and the air guide groove is connected to the second opening and the air outlet.

[0034] In this embodiment, the structure of the cooking appliance is further defined.

[0035] A surrounding plate is also provided on the side of the stove plate away from the cooking body. The surrounding plate, the outer peripheral surface of the first part of the volute and the stove plate enclose an air guide groove, and the air guide groove has the function of connecting the second opening of the volute and the air outlet. Specifically, the air guide groove is connected to the second opening, and the air guide groove is connected to the air outlet. The fan is used to drive the airflow from the air inlet into the oil fume air duct, enter the flow cavity through the oil fume air duct, flow to the inlet through the flow cavity, and then flow to the volute through the outlet, and then flow to the volute through the volute to the air guide groove, and finally flow from the air guide groove to the air outlet. It can be seen that the air guide groove is used to guide the gas in the volute to the air outlet.

[0036] It can be understood that the air guide groove has the function of guiding gas, and the air guide groove, volute and furnace plate cooperate to limit the flow path of the gas, so that the gas is directed to the air outlet, avoiding the situation where oil smoke flows to other positions of the cooking appliance, and ensuring the cleanliness and hygiene of the inside of the cooking appliance.

[0037] It can be understood that the present application makes reasonable use of the structure of the volute, so that the inner circumferential surface of the volute forms a first opening, and the first part of the outer circumferential surface of the volute also forms a part of the groove wall of the air guide groove. In this way, while ensuring the effectiveness and reliability of the air guide, the material input of the cooking appliance is reduced, which is conducive to reducing the production cost of the cooking appliance.

[0038] In some embodiments, optionally, the furnace plate, the volute and the enclosure are integrally connected.

[0039] In this embodiment, the matching structure of the furnace plate, the volute and the enclosure is further defined.

[0040] Specifically, the furnace plate, the volute and the enclosure are connected in one piece. This structural arrangement simplifies the molding process of the furnace plate, the volute and the enclosure because the assembly process of the furnace plate, the volute and the enclosure is omitted, which is conducive to improving the processing efficiency of the product. In addition, the furnace plate, the volute and the enclosure are connected in one piece to ensure the dimensional accuracy of the product.

[0041] In some embodiments, optionally, the outer circumference of the outer shell, the furnace plate and the second part of the volute encloses an air guide duct, the wind wheel is located between the air guide groove and the air guide duct, and the air guide duct is connected to the air outlet; the cooking appliance also includes a magnetron and a second fan, and the magnetron and the second fan are both located in the air guide duct.

[0042] In this embodiment, the structure of the cooking appliance is further defined.

[0043] The outer shell, the furnace plate and the outer peripheral surface of the second part of the volute enclose a guide air duct, the wind wheel is located between the guide groove and the guide air duct, and the guide air duct is connected to the air outlet.

[0044] The cooking appliance further comprises a magnetron and a second fan. The magnetron is located in the air guide passage, and the second fan is located in the air guide passage.

[0045] When the second fan is working, it can drive the air flow from the air outlet into the guide air duct, and can dissipate heat for the magnetron located in the guide air duct to reduce the working temperature of the magnetron, which is beneficial to prolonging the service life of the magnetron.

[0046] In addition, the outer shell, the furnace plate and the second part of the outer circumference of the volute enclose an air guide duct. The present application reasonably utilizes the structure of the volute so that the inner circumference of the volute forms a first opening, the first part of the outer circumference of the volute also forms a part of the groove wall of the air guide groove, and the second part of the outer circumference of the volute forms a part of the duct wall of the air guide duct. In this way, while ensuring the effectiveness and reliability of the air guide, the material input of the cooking appliance is reduced, which is conducive to reducing the production cost of the cooking appliance.

[0047] It can be understood that the wind wheel is located between the wind guide groove and the guide air duct. The wind wheel is used to separate the wind guide groove and the guide air duct, which can avoid mutual interference between the airflows in the wind guide groove and the guide air duct, and can ensure the effectiveness and feasibility of magnetron heat dissipation.

[0048] In some embodiments, optionally, the cooking appliance further includes: a waveguide located between the shell and the cooking body, the waveguide connecting the magnetron and the cooking cavity.

[0049] In this embodiment, the structure of the cooking appliance is further defined.

[0050] The cooking appliance further comprises a waveguide which communicates the magnetron and the cooking cavity.

[0051] The cooking appliance comprises a microwave generator, and the microwave generator comprises a waveguide, a magnetron, a microwave antenna and a microwave motor.

[0052] In addition, a waveguide is provided between the housing and the cooking body, and the waveguide connects the magnetron and the cooking cavity. The magnetron feeds microwaves into the cooking cavity through the waveguide, and the microwave motor drives the microwave antenna to rotate to achieve the effect of stirring the microwaves, so that the microwaves can be distributed more evenly, improving the uniformity of microwave input into the cooking cavity, and being able to fully heat the food with microwaves, so that the food is evenly heated.

[0053] In some embodiments, optionally, the shell further includes a grille, the grille is located on the top of the cooking body, the grille forms an air outlet, and the grille is connected to the air guide groove.

[0054] In this embodiment, the structure of the housing is further defined.

[0055] The housing further comprises a grille, which forms an air outlet and is connected to the air guide groove, so that the airflow passing through the air guide groove can flow out of the cooking appliance through the grille.

[0056] The grille has the function of limiting the flow path of the airflow, so that the filtered gas can diffuse out of the cooking utensil, thereby accelerating the flow of the airflow.

[0057] In some embodiments, optionally, the housing includes: a top plate, the top plate is provided with a third opening, the third opening is connected to the second opening; and a cover plate, which is openably connected to the top plate, and the cover plate is used to open or close the third opening.

[0058] In this embodiment, the structure of the housing is further defined.

[0059] The housing includes a top plate and a cover plate. The top plate is provided with a third opening, and the third opening is communicated with the second opening. Specifically, the third opening and the second opening are arranged opposite to each other.

[0060] The cover plate is connected to the top plate in an openable and closable manner, and the cover plate is used to open or close the third opening.

[0061] When the cooking appliance is in the external circulation mode, the third opening is opened through the cover plate, and the second opening is connected to the external environment through the third opening. The gas in the volute can flow out of the cooking appliance through the second opening and the third opening.

[0062] When the cooking appliance is in the internal circulation mode, the third opening is closed by the cover plate, and the cover plate blocks the communication between the second opening and the external environment. The gas in the volute cannot flow out of the cooking appliance through the third opening.

[0063] This setting can meet diverse usage needs and is conducive to improving product performance and market competitiveness.

[0064] In some embodiments, optionally, the cooking appliance further includes: a first filter element, disposed at the air inlet; and / or a second filter element, disposed at the air outlet.

[0065] In this embodiment, the structure of the cooking appliance is further defined.

[0066] The cooking appliance further comprises a first filter element. The first filter element is arranged at the air inlet.

[0067] The first filter element has the function of filtering water mist and oil smoke in the air flow to ensure the cleanliness of the gas discharged from the cooking utensil and reduce the pollution to the environment.

[0068] Optionally, the first filter element comprises a metal mesh.

[0069] The cooking appliance also includes a second filter element. The second filter element is arranged at the air outlet.

[0071] Optionally, the filter element comprises a graphite element.

[0072] That is to say, the first filter element and the second filter element cooperate to filter out water mist, oil smoke and smell in the air flow, thereby ensuring the cleanliness and hygiene of the gas flowing out of the cooking utensil and reducing pollution to the environment.

That is, when the cooking appliance 10 is working, the air inlet 110 draws air from the stove, so as to draw the water mist, smoke, etc. generated by cooking on the stove into the oil fume duct 500 and the flow cavity 400, and then discharges it from the air outlet 120 after filtering. This arrangement allows the gas to be discharged in a directional manner, such as by facing the window or away from people, to prevent mist and fumes from spreading indoors, thereby preventing oil stains from adhering to furniture or fumes and odors from adhering to clothing, thereby reducing the impact on the indoor environment.

[0110] Furthermore, the air inlet 110 is located at the bottom 310 of the cooking body, that is, the air inlet 110 is located closer to the stove. In addition, the stove plate 200 is located between the top 320 of the cooking body and the air outlet 120, the stove plate 200 and the cooking body 300 enclose a flow cavity 400, and the inlet 612 of the first fan 600 is connected to the flow cavity 400. That is to say, the flow chamber 400 is connected to the oil fume duct 500 and the inlet 612 of the first fan 600. The space of the flow chamber 400 is large, and the resistance to the air flow is small. In this way, more gas can flow from the air inlet 110 to the air outlet 120, which is conducive to reducing the attenuation of the air volume, so that the water mist, smoke, etc. at the stove can be sucked into the cooking utensil 10 in time, and the working efficiency of the first fan 600 is enhanced. It can be understood that under the condition of the same oil fume absorbing effect, the speed of the motor 620 can be reduced. In this way, the operating noise of the cooking utensil 10 can be reduced when working, which is conducive to improving the product's performance and market competitiveness. At the same time, this setting enables the smoke at the stove to be effectively sucked into the oil fume duct 500, which can reduce the oil fume concentration and surrounding temperature around the cook, and concentrate the oil fume and hot air at the air outlet 120, thereby greatly improving the efficiency of heat and smoke exhaust of the cooking utensil 10.

[0111] In some embodiments, optionally, the oil smoke air duct 500 extends to the flow cavity 400 through a side portion of the cooking body 300 .

[0112] In this embodiment, the matching structure between the oil smoke air duct 500 and the cooking body 300 is further defined.

[0113] The oil fume duct 500 extends to the flow cavity 400 through one side of the cooking body 300. That is, when the first fan 600 is working, the driving airflow enters the oil fume duct 500 from the air inlet 110, flows to the flow cavity 400 through the oil fume duct 500 on one side of the cooking body 300, and then flows to the inlet 612 of the first fan 600 through the flow cavity 400, and then flows to the air outlet 120 through the outlet 614, and finally discharges the cooking appliance 10 through the air outlet 120, so that the water mist, smoke, etc. are effectively guided to the air outlet 120.

[0114] In some embodiments, optionally, the oil smoke air duct 500 extends to the flow cavity 400 through at least two sides of the cooking body 300 .

[0115] In this embodiment, the matching structure between the oil smoke air duct 500 and the cooking body 300 is further defined.

[0116] The oil fume duct 500 extends to the flow chamber 400 through the side portions of at least two sides of the cooking body 300. For example, the oil fume duct 500 includes a plurality of oil fume segments, each of which is located on one side of the cooking body 300, and each of which is connected to the air inlet 110 and the flow chamber 400. This arrangement enables the airflow to converge to the flow chamber 400 from multiple directions and multiple angles when the first fan 600 is working, thereby increasing the flow rate of the airflow, which is beneficial to increasing the air suction capacity of the cooking appliance 10 and improving the oil fume extraction effect of the cooking appliance 10.

[0117] Optionally, when the oil fume duct 500 extends to the flow chamber 400 through the sides of the cooking body 300, the oil fume duct 500 includes a first oil fume section and a second oil fume section, the first oil fume section is located on the first side of the cooking body 300, and the second oil fume section is located on the second side of the cooking body 300. The first oil fume section connects the air inlet 110 and the flow chamber 400, and the second oil fume section connects the air inlet 110 and the flow chamber 400. The first side of the cooking body 300 and the second side of the cooking body 300 are arranged opposite to each other. Alternatively, the first side of the cooking body 300 and the second side of the cooking body 300 are arranged adjacent to each other.

[0118] In some embodiments, optionally, Figure 6 As shown, the axis of the wind wheel 610 is arranged opposite to the middle part 220 of the furnace plate.

[0119] In this embodiment, the matching structure between the wind wheel 610 and the furnace plate 200 is further defined.

[0120] The axis of the wind wheel 610 is arranged opposite to the middle portion 220 of the furnace plate.

[0121] Specifically, the oil fume duct 500 extends to the flow chamber 400 through the side portions of at least two sides of the cooking body 300, and the axis of the wind wheel 610 is arranged opposite to the middle portion 220 of the stove plate. That is, the wind wheel 610 is installed in the middle portion 220 of the stove plate. This arrangement facilitates the reasonable layout of other components of the cooking utensil 10, and the position of the wind wheel 610 is matched with the position of the oil fume duct 500, which can ensure the balance and consistency of the oil fume suction when the first fan 600 is working, so that the water mist, oil fume, etc. at different positions of the stove can be effectively sucked into the cooking utensil 10, which can ensure the oil fume extraction effect of the cooking utensil 10.

[0122] In some embodiments, optionally, Figure 7 As shown, the outer diameter of the wind wheel 610 is denoted as D1.

[0123] The width of the stovetop 200 from the face 12 of the cooker to the back 14 of the cooker is denoted as D2.

[0124] Among them, 3 / 7≤D1 / D2≤6 / 7.

[0125] In this embodiment, the structure of the cooking appliance 10 is further defined.

[0126] The outer diameter of the wind wheel 610 is D1. The width of the stove plate 200 along the face 12 to the back 14 of the cooking utensil is D2. The relationship between D1 and D2 satisfies: 3 / 7≤D1 / D2≤6 / 7.

[0127] That is, the matching size of the wind wheel 610 and the stove plate 200 is limited. This arrangement reasonably utilizes the installation space between the stove plate 200, the housing 100 and the cooking body 300, and increases the outer size of the wind wheel 610. In this way, the fume extraction effect of the first fan 600 can be increased when the rotation speed of the first fan 600 is constant. That is, while ensuring the fume extraction effect of the cooking utensil 10, it is conducive to further reducing the rotation speed of the first fan 600, thereby further reducing the operating noise of the cooking utensil 10 when it is working.

[0128] Specifically, D1 / D2=4 / 7.

[0129] Specifically, D1 / D2=5 / 7.

[0130] In some embodiments, optionally, Figure 4 and Figure 5 As shown, the furnace plate 200 is provided with a volute 700 .

[0131] The inner circumferential surface of the volute 700 forms a first opening 210 .

[0132] The volute 700 is provided with a second opening 710 .

[0133] The second opening 710 communicates with the first opening 210 and the air outlet 120 .

[0134] In this embodiment, the structure of the cooking appliance 10 is further defined.

[0135] The furnace plate 200 is provided with a volute 700, the inner circumference of which forms a first opening 210, and the wind wheel 610 is provided at the first opening 210 of the volute 700. That is, the volute 700 serves as a mounting carrier for the wind wheel 610, has the function of mounting and fixing the wind wheel 610, can ensure the matching size of the wind wheel 610 and the first opening 210, and provides structural support for the airflow to flow from the air inlet 110 to the air outlet 120 under the action of the wind wheel 610. The airflow flows into the outlet 614 through the inlet portion 612, then flows into the first opening 210 through the outlet portion 614, then flows into the second opening 710 through the first opening 210, and finally flows to the air outlet 120.

[0136] It is understandable that the inner surface of the volute 700 has the function of limiting the flow path of the gas, so that the gas is directed to the air outlet 120, thereby preventing the oil smoke from flowing to other positions of the cooking appliance 10.

[0137] The volute 700 has a pressure-expanding function. The velocity of the airflow flowing into the air inlet 110 is relatively high. The volute 700 with a uniformly increased flow area reduces the deflection of the airflow, reduces the flow loss of the airflow, and converts more energy into static pressure, thereby increasing the air volume, avoiding the situation where the flow loss of the airflow is large due to excessive velocity, the aerodynamic performance is poor, and the air volume is reduced. At the same time, the volute 700 has a flow-collecting function, reducing the frequency of airflow separation, de-flow, vortex and other phenomena, which is conducive to further reducing the operating noise of the cooking appliance 10 and improving the fume extraction effect of the cooking appliance 10.

[0138] In some embodiments, optionally, Figure 4 and Figure 5 As shown, a surrounding plate 800 is further provided on the side of the stove plate 200 facing away from the cooking body 300 .

[0139] The enclosing plate 800 , the first portion of the outer peripheral surface 720 of the volute and the furnace plate 200 enclose an air guide groove 900 .

[0140] The air guiding groove 900 communicates with the second opening 710 and the air outlet 120 .

[0141] In this embodiment, the structure of the cooking appliance 10 is further defined.

[0142] A side of the stove plate 200 facing away from the cooking body 300 is also provided with a surrounding plate 800. The surrounding plate 800, the first part of the outer peripheral surface 720 of the volute and the stove plate 200 enclose an air guide groove 900. The air guide groove 900 has the function of connecting the second opening 710 of the volute 700 and the air outlet 120. Specifically, the air guide groove 900 is connected to the second opening 710, and the air guide groove 900 is connected to the air outlet 120. The fan is used to drive the air flow from the air inlet 110 into the oil fume air duct 500, enter the flow cavity 400 through the oil fume air duct 500, flow to the inlet 612 through the flow cavity 400, and then flow to the volute 700 through the outlet 614, and then flow to the air guide groove 900 through the volute 700, and finally flow to the air outlet 120 from the air guide groove 900. It can be seen that the air guide groove 900 is used to guide the gas in the volute 700 to the air outlet 120.

[0143] It can be understood that the air guide groove 900 has the function of guiding gas, and the air guide groove 900, the volute 700 and the furnace plate 200 cooperate to limit the flow path of the gas, so that the gas is directed to the air outlet 120, avoiding the occurrence of oil smoke flowing to other positions of the cooking utensil 10, and ensuring the cleanliness and hygiene of the inside of the cooking utensil 10.

[0144] It can be understood that the present application reasonably utilizes the structure of the volute 700, so that the inner circumferential surface of the volute 700 forms a first opening 210, and the first part of the outer circumferential surface 720 of the volute also forms a part of the groove wall of the air guide groove 900. In this way, while ensuring the effectiveness and reliability of the air guide, the material input of the cooking utensil 10 is reduced, which is conducive to reducing the production cost of the cooking utensil 10.

[0145] In some embodiments, optionally, the furnace plate 200, the volute 700 and the enclosure 800 are integrally connected.

[0146] In this embodiment, the matching structure of the furnace plate 200, the volute 700 and the enclosure 800 is further defined.

This structural arrangement simplifies the molding process of the furnace plate 200, the volute 700 and the enclosure 800 because the assembly process of the furnace plate 200, the volute 700 and the enclosure 800 is omitted, which is conducive to improving the processing efficiency of the product. In addition, the furnace plate 200, the volute 700 and the enclosure 800 are connected in one piece to ensure the dimensional accuracy of the product.

[0161] In addition, the outer shell 100, the furnace plate 200 and the second portion of the outer peripheral surface 730 of the volute enclose an air guide duct 1000. The present application reasonably utilizes the structure of the volute 700, so that the inner peripheral surface of the volute 700 forms a first opening 210, the first portion of the outer peripheral surface 720 of the volute also forms a portion of the groove wall of the air guide groove 900, and the second portion of the outer peripheral surface 730 of the volute forms a portion of the duct wall of the air guide duct 1000. In this way, while ensuring the effectiveness and reliability of the air guide, the material input of the cooking appliance 10 is reduced, which is conducive to reducing the production cost of the cooking appliance 10.

[0162] It can be understood that the wind wheel 610 is located between the wind guide groove 900 and the guide air duct 1000. The wind wheel 610 is used to separate the wind guide groove 900 and the guide air duct 1000, which can avoid mutual interference between the airflows in the wind guide groove 900 and the guide air duct 1000, and can ensure the effectiveness and feasibility of heat dissipation of the magnetron 1100.

[0163] In some embodiments, optionally, Figure 4 As shown, the cooking appliance 10 also includes a waveguide 1300 .

The magnetron 1100 feeds microwaves into the cooking cavity through the waveguide 1300, and the microwave motor 620 drives the microwave antenna to rotate to achieve the effect of stirring the microwaves, so that the microwaves can be more evenly distributed, and the uniformity of the microwave input into the cooking cavity is improved, so that the food can be fully heated by microwaves, so that the food is evenly heated.

[0170] In some embodiments, optionally, Figure 3 and Figure 4 As shown, the housing 100 further includes a grille 130 .
