Technical Field

[0001] This application relates to the field of mechanical technology, and in particular to a multifunctional cooking appliance. Background Technology

[0002] As living standards improve, small kitchen appliances are becoming increasingly popular, such as various cookware, ovens, and air fryers.

[0003] However, existing cookware, ovens, and air fryers all use bottom heating or top heating. In particular, ovens and air fryers use top heating or bottom heating. As food is piled at the bottom of the pot, and due to air convection issues, it is easy for the food to be heated unevenly. Summary of the Invention

[0004] Therefore, it is necessary to provide a multifunctional cooking appliance that can heat food evenly, addressing the aforementioned technical problems.

[0016] The fan blade is fixed to one end of the support frame near the side wall of the first pot body, and the fan blade is connected to the motor, which is used to drive the fan blade.

[0017] In one embodiment, the second grid is uniformly or non-uniformly disposed on the entire side wall of the second pot body, or the second grid is uniformly or non-uniformly disposed on a portion of the side wall of the second pot body.

[0018] In one embodiment, the height of the second pot body is lower than the height of the first pot body, so that when the lid is placed on the first pot body, there is a gap between the second pot body and the lid.

[0019] In one embodiment, the apparatus further includes:

[0020] A rotary motor is located at the bottom of the first pot body and is connected to a rotary shaft. The rotary motor is used to drive the rotary shaft to rotate. A first motor base is also provided at the bottom of the second pot body. When the second pot body is placed inside the first pot body, the rotary shaft meshes with the first motor base, and the rotary motor drives the rotary shaft to rotate. The rotary shaft drives the second pot body to rotate through the first motor base.

[0021] In one embodiment, the second heating element is a heating plate with a motor mounting hole in the middle. The heating plate is fixed to the bottom of the first pot body, and the rotary motor is fixed to the bottom of the first pot body through the motor mounting hole.

[0022] In one embodiment, the height of the rotating shaft is equal to or lower than the height of the heating plate, the first motor base protrudes from the bottom of the second pot body, and when the second pot body is fixed inside the first pot body, the first motor base extends into the motor mounting hole so that the first motor base engages with the rotating shaft.

[0023] In one embodiment, the height of the rotating shaft is greater than the height of the heating plate, the first motor base is recessed at the bottom of the second pot body, and when the second pot body is fixed inside the first pot body, the rotating shaft is inserted into the first motor base to engage with the first motor base.

[0024] In one embodiment, the apparatus further includes:

[0025] The third pot body is detachably fixed inside the first pot body. The third pot body is in contact with the second heating element so that the first heating element heats the pressure cooker body and when the lid is closed on the first pot body, the third pot body and the lid form a sealed space.

[0026] In one embodiment, the cover is also provided with a vent hole, which is opened when the air pressure in the sealed space formed by the three pots and the cover is greater than a preset value.

[0027] In one embodiment, the apparatus further includes:

[0028] A controller is disposed on the side wall of the first pot body and is connected to the first heating element. The controller is used to control the operation of the first heating element.

[0029] In one embodiment, the appliance further includes a second heating element, and the controller is connected to the second heating element. The controller is also used to control the operation of the second heating element. When the second pot body is installed in the first pot body, the controller controls the first heating element and the second heating element to work. When the third pot body is installed in the first pot body, the controller controls the second heating element to work, and the first heating element stops working.

[0030] In one embodiment, the controller is also connected to a fan motor, and the controller is used to control the operation of the fan motor. When the second pot body is installed in the first pot body, the controller controls the operation of the fan motor.

[0032] The aforementioned multi-functional cooking appliance has a first grid at a preset position on the first pot body and a second grid at a corresponding preset position on the side wall of the second pot body. The first and second grids are positioned opposite each other, allowing air convection within the second pot body via a convection component. This convection component is directly opposite the first heating element, thus heating the generated air. The heated air flows through the first and second grids into the second pot body, passing over the food inside and providing uniform heating. Since the air flowing into the second pot body is heated, the air in contact with the food is also heated, achieving uniform heating of the food. Attached Figure Description

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0066] Specifically, please combine Figures 1 to 12 As shown, this application provides a multifunctional appliance based on sidewall heating, which may include a lid 100, a first pot body 200, a second pot body 300, a first heating element 500, and a convection element 600. Specifically, as... Figure 1As shown, the lid 100 is detachably fitted onto the first pot body 200. When it is necessary to replace the pot body inside the first pot body 200 or to remove or add food from the pot body inside the first pot body 200, the lid 100 can be removed. When the appliance is working normally, such as when heating, the lid 100 is fixed onto the first pot body 200 to ensure the normal operation of the appliance.

[0067] The first pot body 200 is equipped with a first heating element 500 on its side wall. When in operation, the first heating element 500 heats the second pot body 300 placed inside the first pot body 200, thereby heating the food inside the second pot body 300. Specifically, to ensure uniform heating of the food inside the second pot body 300, the air flowing into the second pot body 300 needs to be uniformly heated. In this application, a first grid 201 is set at a preset position on the first pot body 200, for example, at the position corresponding to the first heating element 500. Optionally, the first heating element 500 faces the first grid 201, and a second grid 301 is set at a preset position on the second pot body 300 corresponding to the preset position on the first pot body 200. Thus, the first grid 201 and the second grid 301 are opposite each other, allowing the air heated by the first heating element 500 to flow into the second pot body 300 through the first grid 201 and the second grid 301, thereby heating the food inside the second pot body 300.

[0068] Furthermore, in order to ensure that air flows into the second pot body 300, the appliance of this application is also provided with a convection component 600. The convection component 600 is fixed to the side wall of the first pot body 200 and faces the first heating component 500, so that the flowing air generated by the convection component 600 is heated by the first heating component 500 and then flows into the second pot body 300 through the first grid 201 and the second grid 301 to heat the food in the second pot body 300.

[0069] The first heating element 500 can be a heating tube, with both ends connected to the boundary of the first grid 201. The first heating element 500 can include multiple heating tubes, or it can be a spiral heating element whose entire spiral area corresponds to the first grid 201. The convection element 600 covers the first heating element 500 and blows air into it, heating the air. The heated air then flows through the first grid 201 and the second grid 301 into the second pot body 300 to heat the food inside. This ensures uniform heating of the air within the second pot body 300, thus guaranteeing uniform heating of the food. The first heating element 500 and the convection element 600 can be disposed on the outer wall of the first pot body 200.

[0070] The aforementioned multi-functional cooking appliance has a first grid 201 set at a preset position on the first pot body 200 and a second grid 301 set at a corresponding preset position on the side wall of the second pot body 300. The first grid 201 and the second grid 301 are positioned opposite each other, allowing air convection within the second pot body 300 via the convection component 600. The convection component 600 is directly opposite the first heating component 500, thus heating the air generated by the convection. The heated air flows into the second pot body 300 through the first grid 201 and the second grid 301, passing over the food within the second pot body 300 and providing uniform heating. Since the air flowing into the second pot body 300 is heated, the air in contact with the food is also heated, achieving uniform heating of the food.

[0071] In one embodiment, the above-mentioned multifunctional appliance may further include: a second heating element 700, which is located at the bottom of the first pot body 200 and is used to heat the bottom of the second pot body 300 placed inside the first pot body 200.

[0072] The second heating element 700 is located at the bottom of the first pot body 200, so that the second heating element 700 can also heat the bottom of the second pot body 300 placed inside the first pot body 200. Combined with the first heating element 500 set on the side wall of the first pot body 200, the side wall and the bottom are heated together to form a three-dimensional grilling mode to heat the food quickly and evenly.

[0073] Specifically, when the second pot body 300 is placed inside the first pot body 200 and the lid 100 is placed on the first pot body 200, the first heating element 500 and the second heating element 700 can be controlled to heat together. The first heating element 500 heats the air drawn in by the convection element 600, and then the heated air flows into the second pot body 300 through the first grid 201 and the second grid 301. The second heating element 700 heats the bottom of the second pot body 300, thus heating the bottom of the food in the second pot body 300. This forms a three-dimensional grilling mode, which can quickly and evenly heat the food.

[0074] The appliance also includes a rotary fan motor 602, which is located at the bottom of the first pot body 200 and connected to a rotary shaft 702. The rotary fan motor 602 drives the rotary shaft 702 to rotate. The bottom of the second pot body 300 is also provided with a first motor base 302. When the second pot body 300 is placed inside the first pot body 200, the rotary shaft 702 meshes with the first motor base 302, and the rotary motor 701 drives the rotary shaft 702 to rotate. The rotary shaft 702 drives the second pot body 300 to rotate through the first motor base 302.

[0075] Optionally, the second heating element 700 is a heating plate with a motor mounting hole 703 in the middle. The heating plate is fixed to the bottom of the first pot body 200, and the rotating fan motor 602 is fixed to the bottom of the first pot body 200 through the motor mounting hole 703.

[0076] As shown in the attached drawings, the second heating element 700 is a heating plate with a motor mounting hole 703 in the center. For example, it can be annular. In other embodiments, the heating plate can be an irregular shape with a square outer edge and a circular inner edge. The heating plate is fixed to the bottom of the first pot body 200, and the rotary motor 701 is also fixed to the bottom of the first pot body 200 and located inside the motor mounting hole 703. The motor mounting hole 703 is the cavity in the center of the heating plate, usually located in the exact middle of the heating plate, to ensure that the pot body in contact with the heating plate can rotate. Optionally, the motor mounting hole 703 can also be a circular track, so that one of the rotary motors 701 can drive the second pot body 300 in contact with the heating plate to move along the track, that is, to rotate along the track. For example, one or more rotary motors 701 have a rotating shaft 702 on the track, and the rotating shaft 702 corresponds to the first motor seat 302 at the bottom of the second pot body 300, and the rotation of the second pot body 300 is driven by the movement of the rotating shaft 702 on the track.

[0077] Furthermore, the rotating shaft 702 of the rotating motor 701 of the second heating element 700 is connected to the first motor base 302 at the bottom of the second pot body 300. This allows the rotating motor 701 to drive its rotating shaft 702, which in turn drives the first motor base 302, thus causing the second pot body 300 to rotate. This further ensures uniform heating of the bottom of the second pot body 300. The specific rotation direction can be found in [reference needed]. Figure 6 As shown. Furthermore, the sidewall of the second pot body 300 is provided with a second grid 301. This second grid 301 is evenly or unevenly distributed on the sidewall of the second pot body 300. For example, the second grid can be a vertical grid or a horizontal grid. The shape of the second grid 301 is consistent with the shape of the first grid 201. When a second grid 301 is provided at a predetermined distance on the sidewall of the second pot body 300, that is, when the entire sidewall of the second pot body 300 is provided with second grids 301, the rotating fan motor 602... 701 drives the rotation of the second pot body 300. Different second grids 301 on the second pot body 300 are directly opposite to the first grids 201 on the first pot body 200, so that the air drawn in by the convection component 600 is drawn into the second pot body 300 through the first grids 201 and the different second grids 301, thereby ensuring that the side walls of the second pot body 300 are heated, that is, evenly heated. In addition, the even heating of the bottom of the rotating second pot body 300 by the second heating component 700 can form a three-dimensional grilling mode to evenly heat the food.

[0078] The height of the rotating shaft 702 is equal to or lower than the height of the heating plate. The first motor base 302 protrudes from the bottom of the second pot body 300. When the second pot body 300 is fixed inside the first pot body 200, the first motor base 302 extends into the motor mounting hole 703 so that the first motor base 302 meshes with the rotating shaft 702.

[0079] The height of the rotating shaft 702 is greater than the height of the heating plate. The first motor base 302 is recessed at the bottom of the second pot body 300. When the second pot body 300 is fixed inside the first pot body 200, the rotating shaft 702 is inserted into the first motor base 302 to engage with the first motor base 302.

[0080] Specifically, in order to achieve the rotation of the second pot body 300, the first motor base 302 can be protruding from the bottom of the baking pot body 300 or recessed from the bottom of the baking pot body 300.

[0081] Specifically, the height of the rotating shaft 702 can be equal to or lower than the height of the heating plate. Thus, the first motor base 302 can protrude from the bottom of the second pot body 300. The height of the first motor base 302 protruding from the bottom of the second pot body 300 is adapted to the height of the motor mounting hole 703. So when the second pot body 300 is fixed to the first pot body 200, the first motor base 302 is inserted into the motor mounting hole 703 and meshes with the rotating shaft 702. So when the rotating shaft 702 is driven by the rotating motor 701, the first motor base 302 is also driven, thereby driving the second pot body 300 to rotate.

[0082] Furthermore, the height of the rotating shaft 702 can be greater than the height of the heating plate. Thus, the first motor base 302 can be recessed into the bottom of the second pot body 300. The height of the first motor base 302 recessed into the bottom of the second pot body 300 is adapted to the height of the rotating shaft 702 above the second heating element 700, or it is adapted to the height of the rotating shaft 702. When the height of the first motor base 302 recessed into the bottom of the second pot body 300 is adapted to the height of the rotating shaft 702 above the second heating element 700, the motor mounting hole 703 can only be used to install the rotary motor 701, and the height of the rotary motor 701 is... The height of the motor mounting hole 703 is adapted to the height of the rotating shaft 702, so that the entire rotating shaft 702 is higher than the second heating element 700. When the height of the first motor base 302 recessed at the bottom of the second pot body 300 is adapted to the height of the rotating shaft 702, the rotating shaft 702 can be partially located in the motor mounting hole 703. Thus, when the second pot body 300 is fixed in the first pot body 200, the rotating shaft 702 is inserted into the first motor base 302 to engage with the first motor base 302. Therefore, when the rotating shaft 702 is driven by the rotating motor 701, the first motor base 302 is also driven, thereby driving the second pot body 300 to rotate.

[0083] In the above embodiment, not only is the food in the second pot 300 heated by the first heating element 500 on the side wall of the first pot 200, but the food in the second pot 300 is also heated by the second heating element 700 at the bottom of the first pot 200, forming a three-dimensional grilling mode to heat the food evenly.

[0084] In one embodiment, the convection component 600 may include a support frame 601, a fan motor 602, and fan blades 603. The support frame 601 is fixed to the side wall of the first pot body 200. The support frame 601 may be a cuboid support frame 601. The bottom perimeter of the support frame 601 is directly connected to the side wall of the first pot body 200, or it is integrally cast with the first pot body 200, and it is directly opposite the first heating component 500 installed on the first side wall. A fan motor 602 is located at the other end of the support frame 601 and is driven by the output of the fan motor 602 shaft. The fan blade 603 is fixed to the end of the support frame 601 near the side wall of the first pot 200 and is connected to the fan motor 602 shaft. In this way, the fan motor 602 can drive the fan blade 603 to rotate, thereby drawing in outside air, which is then heated by the first heating element 500 on the side wall of the first pot 200, thereby forming hot air. The hot air is then sent into the second pot 300 through the first grid 201 and the second grid 301, thereby heating the food in the second pot 300.

[0085] In the above embodiment, a convection component 600 is formed by a support frame 601, a fan motor 602, and a fan blade 603. This allows outside air to be drawn in and heated by the first heating element 500 on the side wall of the first pot body 200, thereby generating hot air. The hot air is then sent into the second pot body 300 through the first grid 201 and the second grid 301, thereby heating the food inside the second pot body 300.

[0086] In one embodiment, the second grid 301 is uniformly or non-uniformly disposed on the entire side wall of the second pot body 300, or the second grid 301 is uniformly or non-uniformly disposed on a portion of the side wall of the second pot body 300.

[0087] Specifically, as shown in the attached drawings, the first grid 201 is located on the first pot body 200. The second grid 301 is located on the second pot body 300. The second grid 301 may be evenly or unevenly distributed on the side wall of the second pot body 300. For ease of placement, markings may be provided on the first pot body 200 and the second pot body 300. For example, a first marking may be provided on the first pot body 200 and a second marking may be provided on the second pot body 300. When in use, the user aligns the first and second markings to align the second grid 301 and the first grid 201, and the second inner pot can be placed without rotating. If the second grid 301 is evenly or unevenly arranged on the entire side wall of the second pot body 300, the above-mentioned markings are not required. The second inner pot can rotate in this way. As the rotating fan motor 602701 drives the second pot body 300 to rotate, the different second grids 301 on the second pot body 300 are directly opposite the first grid 201 on the first pot body 200. This allows the air drawn in by the convection component 600 to be drawn into the second pot body 300 through the first grid 201 and the different second grids 301, thereby ensuring that the side wall of the second pot body 300 is heated, that is, evenly heated. In addition, the even heating of the bottom of the rotating second pot body 300 by the second heating component 700 can form a three-dimensional grilling mode to evenly heat the food.

[0088] In the above embodiments, the grid on the second pot body 300 can be of various forms, and no specific limitation is made here.

[0089] In one embodiment, the height of the second pot body 300 is lower than the height of the first pot body 200, so that when the lid 100 is closed on the first pot body 200, a gap 900 is left between the second pot body 300 and the lid 100.

[0090] like Figure 8 The design height of the second pot body 300 creates a gap 900 between the lid 100 and the second pot body 300. Steam generated during baking and cooking rises and, under the influence of the airflow from the convection component 600, is quickly expelled through the gap 900, thus carrying away some moisture. This achieves better baking and cooking results. Optionally, the lid 100 can be provided with a vent 101, allowing the carried-away moisture to flow out.

[0091] Specifically, existing pressure cookers lack baking or cooking capabilities due to the lack of air circulation inside the pot, resulting in poor baking performance. Existing ovens also lack pressure cooker cooking functions. This means that users need to purchase either a pressure cooker or an oven separately, and these appliances occupy significant space in the kitchen. To avoid these issues, the multi-functional appliance of this application may further include a third pot body 400, which is detachably fixed within the first pot body 200. When the lid 100 is closed onto the first pot body 200, the third pot body 400 and the lid 100 form a sealed space.

[0092] In other words, when using pressure cooking, a third pot body 400 is used. This third pot body 400 is a pot body without the second grid 301. The third pot body 400 is slightly taller and effectively seals with the lid 100, forming a sealed container. The side of the third pot body 400 contacts the first heating element 500, allowing it to be heated, thus achieving the pressure cooker effect. Furthermore, a second heating element 700 is also provided at the bottom of the first pot body 200. Optionally, to achieve the pressure cooker effect, the second heating element 700 can be used instead of the first heating element 500. In this way, the second heating element 700 heats the bottom of the third pot body 400, thereby achieving the pressure cooker effect.

[0093] If the height of the rotating shaft 702 is equal to or lower than the height of the heating plate, the bottom of the third pot body 400 is in contact with the heating plate. When the third pot body 400 is fixed inside the first pot body 200, the controller 800 controls the rotating motor 701 to not work. At this time, the second motor seat at the bottom of the third pot body 400 protrudes into the first pot body 200, or there is no need to set a second motor seat at the bottom of the third pot body 400. When a second motor seat is set at the bottom of the third pot body 400, the third pot body 400 can be fixed inside the first pot body 200 by engaging with the rotating shaft 702. When a second motor seat is not set at the bottom of the third pot body 400, the third pot body 400 can be fixed by sealing the third pot body 400 with the lid or by setting a buckle at the edge of the first pot body 200. Since the height of the rotating shaft 702 is equal to or lower than the height of the heating plate, the bottom of the third pot body 400 can contact the heating plate, thereby enabling the second heating element 700 to heat the third pot body 400.

[0094] Optionally, the cover 100 is also provided with a vent 101. When the air pressure in the sealed space formed by the three pots and the cover 100 is greater than a preset value, the vent 101 is opened.

[0095] When the pressure cooker effect is achieved, if the pressure inside the third pot 400 exceeds the preset value, the vent 101 can be opened to release the pressure and ensure safety.

[0096] Optionally, a controller 800 is also provided on the side wall of the first pot body 200 of the aforementioned multifunctional appliance. This controller 800 can be connected to the fan motors 602 of the first heating element 500, the second heating element 700, and the convection element 600, allowing the controller 800 to control the operation of these components. Furthermore, if a rotary fan motor 602701 is also provided, the controller 800 can be connected to it to control its operation, thereby controlling the rotation of the second pot body 300. The controller 800 is also connected to the rotary fan motor 602. When the second pot body 300 is fixed inside the first pot body 200, the controller 800 controls the rotary fan motor 602 to operate; when the third pot body 400 is fixed inside the first pot body 200, the controller 800 controls the rotary fan motor 602 to not operate.

[0097] Specifically, the appliance in this application can achieve both a baking mode and a pressure cooker mode. When the appliance is in baking mode, the second pot body 300 is placed inside the first pot body 200. After receiving a user input command, the controller 800 controls the fan motor 602 to start. This causes the fan motor 602 of the convection component 600 to rotate the fan blades 603, thereby drawing air into the first pot body 200. The controller 800 also controls the first heating element 500 to operate, so the drawn-in air becomes hot air after passing through the first heating element 500. The hot air then flows through the first grid 201 and the second grid 301 into the second pot body 300, reaching the food placed inside, thus achieving the baking mode. Optionally, the controller 800 can also control the second heating element 700 to start, so that the second heating element 700 heats the bottom of the second pot body 300, thus forming a three-dimensional grilling mode with the first heating element 500, allowing a pile of food to be heated quickly and evenly.

[0098] Optionally, the controller 800 can also control the rotation of the rotary motor 701. The rotating shaft 702 of the rotary motor 701 drives the first motor base 302, which meshes with it, thereby driving the second pot body 300 to rotate. This ensures even heating of the second pot body 300, guaranteeing uniform heating of its bottom. During baking and cooking, the rotation direction of the second pot body 300 driven by the rotary motor 701 is as follows: Figure 7 As shown. Figure 8The design height of the second pot body 300 creates a gap 900 between the lid 100 and the second pot body 300. Water vapor generated during baking and cooking rises and, under the influence of the convection component 600, is quickly expelled through the gap 900 between the pot body and the second pot body 300. This results in better baking and cooking effects.

[0099] When the appliance is in pressure cooker mode, the controller 800 controls the second heating element 700 to work, and the first heating element 500 stops working.

[0100] like Figure 9 As shown, pressure cooking is accomplished by the cooperation of the first pot body 200, the third pot body 400, the lid body 100, and the controller 800.

[0101] Place the third pot body 400 inside the first pot body 200, with the bottom of the third pot body 400 in contact with the second heating element 700. Place the food requiring pressure cooking into the third pot body 400 and close the lid 100. The lid 100 and the third pot body 400 form a sealed container, such as... Figure 11 and Figure 12 As shown.

[0102] The second heating element 700 is activated by the controller 800 to start heating. Since the lid 100 and the third pot body 400 form a sealed container, the heated air expands continuously to form a certain pressure, thereby achieving pressure cooking.

[0103] This application achieves two functions—rotating hot air baking and pressure cooking—by installing a convection fan and heating element through ventilation grilles on the side wall of the outer pot, and a rotary motor 701 installed at the bottom of the outer pot, in conjunction with two different inner pots. This makes baking and cooking faster and more efficient.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
