Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and more particularly, to a cooking appliance. Background Art

[0002] In the related art, an air fryer includes an outer pot, a heat preservation cover, an inner pot, and a heating device. The heating device is disposed between the outer pot and the heat preservation cover. The heat preservation cover is provided with air inlet holes. When baking food materials in the air fryer, the air inlet holes on the heat preservation cover are used for sucking air, and the heating device heats the air entering the air duct through the air inlet holes into hot air, and then blows the hot air into the inner pot. After the hot air bakes the food materials, it enters the air duct through the air inlet holes again to realize the internal circulation for cooking the food materials.

[0003] Due to the use of internal circulation for cooking food materials in the above air fryer, the food materials are extremely prone to flavor mixing, resulting in poor taste for users. Summary of the Invention

[0004] The main object of the present invention is to provide a cooking appliance to solve the problem that in the related art, the air fryer uses internal circulation for cooking food materials, resulting in extremely easy flavor mixing of the food materials.

[0005] To achieve the above object, the present invention provides a cooking appliance, including: a pot body including an outer pot and an inner pot disposed in the outer pot, the outer pot being provided with an air inlet; a pot cover detachably covering the pot body, the pot cover being provided with an air outlet; an air duct structure including a first air duct and a second air duct that are connected to each other, the first air duct being vertically disposed in the pot body, and the second air duct being horizontally disposed in the pot cover; a blower disposed in the first air duct; and a heating device disposed on a side portion of the pot body and located between the first air duct and the second air duct.

[0006] By applying the technical solution of the present invention, during the process of baking food materials in the cooking appliance, the blower sucks the air outside the cooking appliance through the air inlet into the first air duct, and the air reaches the heating device along the vertically disposed first air duct. During the process of passing through the heating device, the air is heated to form hot air. The hot air enters the inner pot along the horizontally disposed second air duct to heat the food materials in the inner pot, and after the hot air heats the food materials, it is discharged out of the cooking appliance through the air outlet on the pot cover. Repeating the above heating process realizes external circulation heating, and the air outside continuously enters the cooking appliance to heat the food materials, so that the food materials in the inner pot are not prone to flavor mixing. Therefore, the technical solution of the present application effectively solves the problem that in the related art, the air fryer uses internal circulation for cooking food materials, resulting in extremely easy flavor mixing of the food materials.

[0007] Further, the outer pot includes a bottom wall and a side wall. The air inlet includes a first air inlet hole provided on the bottom wall and / or a second air inlet hole provided on the rear part of the side wall. The provision of the first air inlet hole and / or the second air inlet hole facilitates the cooking appliance to suck air inward from the outside, improving the heating efficiency. When both the first air inlet hole and the second air inlet hole are provided, air can enter the first air duct from multiple directions, allowing more air to enter and enabling the first air duct to smoothly circulate air.

[0008] Further, the cooking appliance further includes a controller and a first temperature measuring component connected to the controller. The controller is provided inside the pot body or the pot lid. The controller is connected to the heating device. The first temperature measuring component is provided at the mouth of the pot body. The first temperature measuring component can detect the cooking temperature inside the inner pot and can promptly transmit the temperature inside the inner pot to the controller, so as to accurately control the temperature inside the inner pot.

[0009] Further, the cooking appliance further includes a second temperature measuring component connected to the controller. The second temperature measuring component is provided at the heating device. The second temperature measuring component can detect the heating temperature of the heating device, prevent the temperature of the heating device from being too high and exceeding the defined temperature inside the controller, and plays a role in protecting the cooking appliance.

[0010] Further, the blower is an axial flow blower. When using an axial flow blower to blow air towards the heating device, compared with a centrifugal blower, the exhaust direction of the axial flow blower is parallel to the axis of the axial flow blower, and it can exhaust air evenly. In this way, uniform air can be generated inside the first air duct. When the uniform air passes through the heating device, uniform hot air can be generated. The uniform hot air can blow towards the food ingredients through the second air duct, making the food ingredients heat evenly, and the user can obtain a better taste.

[0011] Further, to facilitate the removal and placement of the inner pot from the outer pot, a notch is provided on the side wall of the outer pot, and the inner pot can be placed into the outer pot through the notch, which facilitates the user to remove or place the inner pot.

[0012] Further, the outer pot includes a housing, a base located at the bottom of the housing, and a middle ring located at the top of the housing. The housing forms the side wall of the outer pot, the base forms the bottom wall of the outer pot, the notch is provided on the housing, and the middle ring, the housing, and the base together enclose an accommodation space, and the inner pot is placed in the accommodation space. When the pot lid is covered on the pot body, the middle ring can support the pot lid so that the pot lid can be stably placed above the inner pot.

[0013] Further, at least part of the pot lid is of a transparent structure. In the above structure, during the process of the cooking appliance cooking food ingredients, the user can directly and comprehensively see the cooking situation inside the inner pot through the transparent structure from above the cooking appliance and can know the cooking effect in real time.

[0014] Further, the cooking appliance further includes a flow disturbing member disposed between the blower and the heating device. The flow disturbing member divides the outlet of the first air duct into at least two sub-outlets. In the above structure, when the air flows to the flow disturbing member, since the first air duct is divided into at least two sub-outlets, the air at each sub-outlet will flow circumferentially along the outlet. By changing the setting position of the flow disturbing member, the air volume at each air outlet position at the outlet of the first air duct can be reasonably adjusted, so as to guide part of the air flowing circumferentially along the outlet of the first air duct to the middle of the outlet of the first air duct, increasing the air volume in the middle of the outlet of the first air duct, thus facilitating the air to blow out the heat at the middle of the outlet of the first air duct, reducing the heat radiated from the middle of the outlet of the first air duct to the blower, and reducing the damage to the middle area on the side of the blower close to the heating device or the motor, thereby effectively improving the service life of the cooking appliance.

[0015] Further, the cooking appliance further includes a wind guide cylinder, which has a wind guide section and a pressurizing section connected in communication. The blower is disposed in the wind guide section, and the heating device is disposed between the second air duct and the pressurizing section. Wherein, one end of the wind guide section away from the pressurizing section forms the inlet of the first air duct, one end of the pressurizing section away from the wind guide section forms the air outlet of the first air duct, and the cross-sectional area of the pressurizing section gradually decreases along the direction from the inlet of the first air duct to the outlet of the first air duct. In the above structure, under the action of the blower, the air flows from the inlet of the first air duct to the outlet of the first air duct. When the air passes through the pressurizing section, since the cross-sectional area of the pressurizing section gradually decreases along the direction from the inlet of the first air duct to the outlet of the first air duct, the air pressure at the outlet of the first air duct can be increased, so as to increase the wind pressure of the hot air, thus facilitating the hot air to better blow to the bottom of the inner pot, so as to better cook the bottom layer of the food, thereby improving the cooking effect of the cooking appliance.

[0016] Further, the cooking appliance further includes a flow guiding structure disposed in the second air duct. The surface of the flow guiding structure close to the inlet of the second air duct forms a first air guiding surface, and the first air guiding surface is an arc surface protruding towards the inlet of the second air duct in the middle. There is a distance between both ends of the first air guiding surface and the air duct wall of the second air duct. In the above structure, the hot air entering from the inlet of the second air duct will contact the first air guiding surface. Under the guidance of the first air guiding surface, part of the air blows directly downward to blow to the rear side of the inner pot; another part of the air flows along the length direction of the first air guiding surface to the left and right sides of the pot cover and is guided to the inner side wall of the cover body. This part of the hot air can blow to the edge of the inner pot and the front side of the inner pot under the guidance of the inner side wall of the cover body. The above structure enables hot air to flow into the front side, rear side, left and right sides of the inner pot, so that the heat field in the inner pot is more uniform.

[0017] Further, the pot lid includes a lid body, a wind guide shell, and a wind guide plate. The wind guide shell is arranged on the inner wall of the lid body. A second air duct is formed inside the wind guide shell. The outlet of the second air duct is located on one side of the lid body. The surface of the wind guide plate close to the outlet of the second air duct forms a second wind guide surface. A flared opening is formed between the wind guide plate and the inner wall of the lid body. The above structure makes the second wind guide surface a smooth arc surface, reducing wind resistance and enabling hot air to flow smoothly into the inner pot, improving the baking efficiency. In addition, the above structure can also increase the contact area between the hot air and the second wind guide surface, thereby providing more wind guide directions and further improving the uniformity of the thermal field in the inner pot.

Detailed Embodiments

[0026] In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships.

In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] As Figures 1 to 3 shown, the cooking appliance of this embodiment includes: a pot body 1, a pot lid 50, an air duct structure 40, a blower 31, and a heating device 32. The pot body 1 includes an outer pot 10 and an inner pot 20 disposed within the outer pot 10. An air inlet 111 is provided on the outer pot 10. The pot lid 50 is detachably covered on the pot body 1. An air outlet 53 is provided on the pot lid 50. The air duct structure 40 includes a first air duct 41 and a second air duct 42 that are in communication with each other. The first air duct 41 is vertically disposed within the pot body 1, and the second air duct 42 is horizontally disposed within the pot lid 50. The blower 31 is disposed within the first air duct 41. The heating device 32 is disposed on the side of the pot body 1 and between the first air duct 41 and the second air duct 42.

[0030] Applying the technical solution of this embodiment, during the process of the cooking appliance baking food materials, the blower 31 sucks the air outside the cooking appliance into the first air duct 41 through the air inlet, and the air reaches the heating device 32 along the vertically arranged first air duct 41. During the process of passing through the heating device 32, the air is heated to form hot air. The hot air enters the inner pot 20 along the horizontally arranged second air duct 42 to heat the food materials in the inner pot 20, and the hot air is discharged outside the cooking appliance through the air outlet 53 on the pot lid 50 after heating the food materials. Repeating the above heating process realizes external circulation heating, and the external air continuously enters the cooking appliance to heat the food materials, so that the food materials in the inner pot 20 are not prone to flavor mixing. Therefore, the technical solution of this embodiment effectively solves the problem that the food materials are extremely prone to flavor mixing due to the use of internal circulation to cook food materials in the related art of air fryers.

[0031] In this embodiment, the air outlet 53 is directly communicated with the inside of the inner pot 20. In this way, during the process of the cooking appliance realizing external circulation heating, after the hot air heats the food materials in the inner pot 20, it is directly discharged into the atmosphere outside the cooking appliance through the air outlet 53, minimizing the hot air that continues to stay in the inner pot 20 after heating the food materials, ensuring that the external air continuously enters the cooking appliance, and the hot air after heating the food materials can be continuously discharged outside the cooking appliance, so that the cooking appliance is always in the state of external circulation heating, greatly reducing the possibility of flavor mixing.

[0032] It should be noted that the axis of the above-mentioned blower 31 is parallel to the air exhaust direction of the first air duct 41. Specifically, the first air duct 41 being arranged vertically means that the first air duct 41 is perpendicular to the bottom surface of the cooking appliance or forms an angle greater than or equal to 45° with the bottom surface of the cooking appliance. The above-mentioned second air duct 42 being arranged horizontally means that it is parallel to the bottom surface of the cooking appliance or forms an angle less than 45° with the bottom surface of the cooking appliance.

[0033] In this embodiment, the first air duct 41, the blower 31, and the heating device 32 are all arranged on the side of the pot body 1, which reduces the overall height of the cooking appliance and avoids occupying too much external space.

[0034] Such as Figure 2 and Figure 3As shown, the outer pot 10 includes a bottom wall 11 and a side wall 12. The air inlet 111 includes a first air inlet hole 112 provided on the bottom wall 11 and a second air inlet hole 113 provided on the rear part of the side wall 12. The arrangements of the first air inlet hole 112 and the second air inlet hole 113 facilitate the cooking appliance to suck air inward from the outside, improving the heating efficiency. When both the first air inlet hole 112 and the second air inlet hole 113 are provided, air can enter the first air duct 41 from multiple directions, allowing more air to enter and enabling the first air duct 41 to smoothly circulate air. The rear part of the above-mentioned side wall 12 refers to the side of the cooking appliance facing away from the user. Specifically, it is arranged opposite to the position of the handle 22 on the inner pot body 21 in the following text.

[0035] Of course, in embodiments not shown in other figures, the air inlet only includes the first air inlet hole provided on the bottom wall or the second air inlet hole provided on the rear part of the side wall.

[0036] In this embodiment, the blower 31 is an axial flow blower. When the axial flow blower 31 blows air towards the heating device 32, compared with a centrifugal blower, the exhaust direction of the axial flow blower 31 is parallel to the axis of the axial flow blower 31, enabling uniform air exhaust. In this way, uniform air can be generated in the first air duct 41. When the uniform air passes through the heating device, uniform hot air can be generated. The uniform hot air can blow towards the food through the second air duct 42, making the food evenly heated and allowing the user to obtain a better taste.

[0037] As Figures 2 to 4 shown, the cooking appliance further includes a controller and a first temperature measuring component 61 connected to the controller. The controller is arranged inside the pot body 1. The controller is connected to the heating device 32, and the first temperature measuring component 61 is arranged at the mouth of the pot body 1. The first temperature measuring component 61 can detect the cooking temperature inside the inner pot 20 and can timely transmit the temperature inside the inner pot 20 to the controller, so as to accurately control the temperature inside the inner pot 20.

[0038] Of course, in embodiments not shown in other figures, the controller is arranged inside the pot lid. The controller is connected to the heating device, and the first temperature measuring component is arranged at the mouth of the pot body.

[0039] As Figure 2 shown, the cooking appliance further includes a second temperature measuring component 62 connected to the controller. The second temperature measuring component 62 is arranged at the heating device 32. The second temperature measuring component 62 can detect the heating temperature of the heating device 32, prevent the temperature of the heating device 32 from being too high and exceeding the defined temperature in the controller, playing a role in protecting the cooking appliance.

[0040] As Figures 1 to 4As shown, when the first temperature measuring component 61 detects that the temperature in the cooking space reaches the first set temperature, the first temperature measuring component 61 sends a first temperature signal to the controller, and the controller controls the heating element 321 to stop heating. When the temperature in the cooking space drops to the second set temperature, the first temperature measuring component 61 sends a second temperature signal to the controller, and the controller controls the heating element 321 to heat; wherein the first set temperature is greater than the second set temperature. When the first temperature measuring component 61 does not send the first temperature signal and the temperature in the cooking space exceeds the first set temperature, the heating element 321 stops heating when the conductor of the second temperature measuring component 62 is disconnected.

[0041] As Figure 4 and Figure 5 shown, in order to facilitate the removal and placement of the inner pot 20 from the outer pot 10, a notch 121 is provided on the side wall 12 of the outer pot 10, and the inner pot 20 can be placed into the outer pot 10 through the notch 121, which facilitates the user to remove or place the inner pot 20.

[0042] As Figure 4 and Figure 5 shown, the outer pot 10 includes a housing 13, a base 14 located at the bottom of the housing 13, and a middle ring 15 located at the top of the housing 13. When the pot cover 50 is covered on the pot body 1, the middle ring 15 can support the pot cover 50 so that the pot cover 50 can be stably placed above the inner pot 20. The housing 13 forms the side wall 12 of the outer pot 10, the base 14 forms the bottom wall 11 of the outer pot 10, and the notch 121 is provided on the housing 13. The middle ring 15, the housing 13 and the base 14 together enclose an accommodation space, and the inner pot 20 is placed in the accommodation space.

[0043] As Figure 3 and Figure 4 shown, the first temperature measuring component 61 is provided on the inner wall of the middle ring 15, and the first temperature measuring component 61 is preferably an NTC thermistor.

[0044] As Figure 2 and Figure 3 shown, the inner pot 20 includes an inner pot body 21 and a handle 22 provided on the inner pot body 21. The provision of the handle 22 facilitates the user to remove and place the inner pot body 21 and improves the convenience of use by the user. In this embodiment, the handle of the handle 22 is a structure bent downward to avoid interfering with the user.

[0045] As Figure 2 and Figure 3As shown, the cooking appliance further includes a flow disturbing member disposed between the blower 31 and the heating device 32. The flow disturbing member divides the outlet of the first air duct 41 into at least two sub-outlets. When the air flows to the flow disturbing member, since the first air duct is divided into at least two sub-outlets, in this way, the air at each sub-outlet will flow along the circumferential direction of the outlet. By changing the setting position of the flow disturbing member, the air volume at each air outlet position at the outlet of the first air duct 41 can be reasonably adjusted, so as to guide part of the air flowing along the circumference of the outlet of the first air duct 41 to the middle of the outlet of the first air duct 41, increasing the air volume in the middle of the outlet of the first air duct 41, thereby being conducive to the air blowing out the heat at the middle of the outlet of the first air duct 41, reducing the heat radiated from the middle of the outlet of the first air duct 41 to the blower, and reducing the damage to the middle area on the side of the blower 31 close to the heating device 32 or the motor, thus effectively improving the service life of the cooking appliance.

[0046] As Figure 2 and Figure 3 As shown, the cooking appliance further includes an air guide cylinder 33. The air guide cylinder 33 has a communicating air guiding section 331 and a pressurizing section 332. The blower 31 is disposed in the air guiding section 331, and the heating device 32 is disposed between the second air duct 42 and the pressurizing section 332. Among them, one end of the air guiding section 331 away from the pressurizing section 332 forms the inlet of the first air duct 41, and one end of the pressurizing section 332 away from the air guiding section 331 forms the air outlet of the first air duct 41. The cross-sectional area of the pressurizing section 332 gradually decreases along the direction from the inlet of the first air duct 41 to the outlet of the first air duct 41. Under the action of the blower, the air flows from the inlet of the first air duct 41 to the outlet of the first air duct 41. When the air passes through the pressurizing section, since the cross-sectional area of the pressurizing section gradually decreases along the direction from the inlet of the first air duct 41 to the outlet of the first air duct 41, in this way, the air outlet pressure at the outlet of the first air duct 41 can be increased, so as to increase the air pressure of the hot air, thereby facilitating the hot air to better blow to the bottom of the inner pot, so as to better cook the bottom layer of the food, thus improving the cooking effect of the cooking appliance.

[0047] As Figure 2 and Figure 3As shown in the figure, the cooking appliance further includes a flow guiding structure disposed in the second air duct 42. The surface of the flow guiding structure close to the inlet of the second air duct 42 forms a first air guiding surface, which is an arc surface protruding towards the inlet of the second air duct 42 in the middle. There is a distance between both ends of the first air guiding surface and the duct wall of the second air duct 42. The hot air entering from the inlet of the second air duct 42 will contact the first air guiding surface. Under the guidance of the first air guiding surface, a part of the air blows directly downward to blow towards the rear side of the inner pot 20; another part of the air flows towards the left and right sides of the lid 50 along the length direction of the first air guiding surface and is guided to the inner side wall of the lid body 51. This part of the hot air can blow towards the edge and the front side of the inner pot 20 under the guidance of the inner side wall of the lid body 51. The above structure enables hot air to flow into the front side, rear side, left and right sides of the inner pot 20, thereby making the heat field in the inner pot 20 more uniform.

[0048] As Figure 2 and Figure 3 shown in the figure, the lid 50 includes a lid body 51, a wind guiding shell 52 and a wind guiding plate. The wind guiding shell 52 is disposed on the inner wall of the lid body 51. The inside of the wind guiding shell 52 forms a second air duct 42. The outlet of the second air duct 42 is located on one side of the lid body 51. The surface of the wind guiding plate close to the outlet of the second air duct 42 forms a second air guiding surface. A flared opening is formed between the wind guiding plate and the inner wall of the lid body 51. The above structure makes the second air guiding surface a smooth arc surface, reducing the wind resistance, enabling the hot air to flow smoothly into the inner pot 20, and improving the baking efficiency. In addition, the above structure can also increase the contact area between the hot air and the second air guiding surface, thereby providing more air guiding directions and further improving the uniformity of the heat field in the inner pot 20.

[0049] As Figures 2 to 4 shown in the figure, in this embodiment, the heating device 32 includes a heating element 321 and a wind guiding cover 322. The heating element 321 is disposed in the wind guiding cover 322. The wind guiding cover 322 is disposed on the middle ring 15 and is located between the wind guiding shell 52 and the wind guiding cylinder 33. The heating element 321 can be a heating disk, a halogen tube or a heating wire. Among them, compared with the heating element 321 being a heating disk or a halogen tube, when the heating element 321 uses a heating wire, the surface area of the heating element 321 is large, and more heat is blown away by the blower 31, which can further improve the heating speed of the cooking appliance.

[0050] As Figure 2 and Figure 3 shown in the figure, the blower 31 includes a motor 311 and an axial flow fan blade 312 disposed on the motor.

[0051] As Figure 3 shown in the figure, the cooking appliance further includes a bracket 34. The motor 311 is connected in the wind guiding cylinder 33 through the bracket 34. In this way, the blower 31 can be stably disposed in the first air duct 41.

[0052] In this embodiment, as Figure 1 and Figure 5 shown, at least a part of the pot lid 50 is a transparent structure. Specifically, the lid body 51 includes a lid portion, an outward convex portion provided on the lid portion, and a glass panel located at the middle position of the lid portion. The glass panel forms a transparent structure. In this way, during the process of the cooking appliance cooking food, the user can directly and comprehensively see the cooking situation in the inner pot 20 through the glass panel from above the cooking appliance, and can know the cooking effect in real time.

[0053] In this embodiment, the cooking appliance includes an air fryer, or a rice cooker, or an electric pressure cooker, or a multi-functional heating pot with baking, cooking, and dish-making functions.

[0054] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0055] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned", etc. can be used here to describe the spatial positional relationships between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientations described in the drawings for the devices. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include two orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations will be made for the spatial relative descriptions used here.

[0056] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of differentiating the corresponding components.
