Cooking utensils

Abstract

This invention provides a cooking appliance, including a shell assembly and a baffle. The shell assembly has a cooking cavity. The baffle is disposed within the cooking cavity and is movable within the cooking cavity to change the boundary of the cooking cavity during operation. Because the baffle can change the boundary of the cooking cavity, when the cooking appliance cooks food using microwaves, it can alter the boundary of the microwave field within the cooking cavity. When microwaves propagate to the boundary of the cooking cavity, they are reflected in different directions as the baffle moves, thus changing the microwave propagation path within the cooking cavity, i.e., changing the distribution of microwaves within the cooking cavity. Furthermore, the microwave propagation path changes with the movement of the baffle, improving the stirring effect of the microwaves and resulting in a more uniform distribution of microwaves within the cooking cavity.

Description

Technical Field

[0001] This invention relates to the field of cooking utensil technology, and more specifically, to a cooking utensil. Background Technology

[0002] Currently, when a microwave oven heats food, the microwaves enter the cooking cavity through the waveguide port and propagate along a fixed path. However, due to the gaps between microwaves on different paths, the food is heated unevenly.

[0003] In related technologies, a rotating tray is placed inside the cooking cavity to improve the uniformity of heating of food. However, as the tray rotates the food, the microwaves on one path still heat the food in a ring-shaped area, and there will still be gaps between adjacent ring-shaped areas, resulting in uneven heating of the food. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, the present invention proposes a cooking utensil.

[0006] In view of this, the present invention provides a cooking appliance, including a shell assembly and a baffle; the shell assembly is provided with a cooking cavity; the baffle is disposed inside the cooking cavity and is movable within the cooking cavity to change the boundary of the cooking cavity when the cooking appliance is in operation.

[0007] The cooking appliance provided by this invention includes a shell assembly with a cooking cavity inside, capable of holding and cooking food. The appliance also includes a baffle that can move within the cooking cavity, thereby altering its boundaries. Because the baffle can change the boundaries of the cooking cavity, when the appliance cooks the food using microwaves, it changes the boundaries of the microwave field within the cavity. When microwaves propagate to the boundary of the cooking cavity, they are reflected in different directions as the baffle moves, thus altering the microwave propagation path within the cavity. This changes the distribution of microwaves within the cavity, and the change in the microwave propagation path with the movement of the baffle enhances the stirring effect, resulting in a more uniform distribution of microwaves within the cooking cavity.

[0008] Because the cooking appliance can drive the movement of the baffle, the microwaves can be distributed more evenly in the cooking cavity, thereby heating more areas of the food and improving the uniformity of heating the food.

[0009] Furthermore, the cooking appliance improves the uniformity of microwave distribution within the cooking cavity by driving the baffle movement. This eliminates the need for a turntable, reducing its space occupation and allowing for a larger food placement area at the bottom of the cavity. This enables the appliance to hold more food, thus improving its overall quality. Eliminating the turntable also simplifies the appliance's structure, resulting in a smoother inner wall for easier cleaning and reducing the difficulty of cleaning the cooking cavity.

[0010] Cooking appliances use baffles to change the boundaries of the cooking cavity, making the structure required to change the boundaries of the cooking cavity simpler and the cost lower. As a result, cooking appliances do not require excessively complex structures to improve the uniformity of microwave distribution, nor do they require excessively increased costs, making cooking appliances more practical.

[0011] Furthermore, the cooking appliance changes the boundary of the cooking cavity through the baffle without altering the structure of the original shell assembly, thus preventing microwave leakage due to the change in the boundary of the cooking cavity and ensuring the safety of the cooking appliance during operation.

[0012] In addition, the cooking utensil in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0013] In one technical solution of the present invention, the shell assembly is provided with an air inlet, and the cooking appliance also includes a fan assembly, which is disposed at the air inlet and is capable of supplying air into the cooking cavity; the baffle is disposed opposite to the air inlet.

[0014] In this technical solution, the shell assembly is equipped with an air inlet, and a fan assembly is positioned opposite the air inlet on the shell assembly. The fan assembly can deliver air into the cooking cavity to bake the food. A baffle is located at the air inlet, which can prevent food or debris from entering the air outlet, thus making it easier for the user to clean the cooking cavity.

[0015] Since baffles can change the boundaries of the cooking cavity and also prevent food or debris from entering the air vent, they have a wider range of functions, thereby simplifying the structure of cooking appliances and reducing their cost.

[0016] Furthermore, by positioning the baffle opposite the air inlet, the airflow is turbulent after exiting the inlet, allowing for more even airflow throughout the cooking cavity and further improving the uniformity of heating the food. In other words, by placing a baffle at the air inlet of the cooking cavity and driving its movement, both the microwaves and the incoming air are distributed more evenly within the cavity, thus enhancing the uniformity of heating the food.

[0017] In one embodiment of the present invention, the cooking appliance further includes a first driving component, which is connected to a baffle to drive the baffle to move closer to or away from the air inlet.

[0018] In this technical solution, the first driving component drives the baffle to move closer to or further away from the air inlet, so that the baffle can reciprocate relative to the air inlet, thereby enabling the baffle to periodically reflect microwaves to different paths, and the microwaves are more evenly distributed in the cooking cavity.

[0019] The first drive assembly drives the baffle to move closer to the air inlet, that is, the first drive assembly drives the baffle to move towards the air inlet, causing the boundary of the cooking cavity to also move towards the air inlet. The first drive assembly drives the baffle away from the air inlet, that is, the first drive assembly drives the baffle to move in a direction away from the air inlet, causing the boundary of the cooking cavity to also move in a direction away from the air inlet.

[0020] In one technical solution of the present invention, the first drive assembly includes a support component, a first connecting shaft and a first motor; the support component is provided with an internal thread; the first connecting shaft passes through the support component and cooperates with the internal thread, and the first end of the first connecting shaft is connected to a baffle; the first motor is connected to the second end of the first connecting shaft.

[0021] In this technical solution, the first drive assembly includes a first connecting shaft and a first motor. A first end of the first connecting shaft is connected to a baffle, and a second end of the first connecting shaft is connected to the first motor. The first connecting shaft has an external thread, which engages with the internal thread of the supporting component. When the first motor drives the first connecting shaft to rotate, the first connecting shaft can move axially under the action of the supporting component, thereby driving the baffle and allowing the baffle to move away from or closer to the air inlet.

[0022] Specifically, the second end of the first connecting shaft is cylindrical and sleeved on the output shaft of the first motor. The first connecting shaft and the output shaft of the first motor are connected by a key, so that the first motor can drive the first connecting shaft to rotate and the first connecting shaft can also move along the axial direction, thereby realizing the driving of the baffle.

[0023] In one embodiment of the present invention, the first driving component includes a telescopic component, the telescopic component includes a telescopic shaft, and the telescopic shaft is connected to a baffle.

[0024] In this technical solution, the first driving component includes a telescopic component. The telescopic shaft of the telescopic component can extend and retract and is connected to the baffle to drive the baffle, so that the baffle can move away from or closer to the air inlet.

[0025] Specifically, the telescopic component can be an electric telescopic rod or a motor with a telescopic output shaft.

[0026] In one technical solution of the present invention, the baffle includes multiple movable parts arranged near the inner wall of the cooking cavity; the multiple movable parts have a first position and a second position, when the multiple movable parts are in the first position, the multiple movable parts are in contact with each other to block the air inlet, and when the multiple movable parts are in the second position, the multiple movable parts are separated to expose the air inlet.

[0027] In this technical solution, the baffle includes multiple movable components. When the multiple movable components are in a first position, they are in contact to block the air inlet. These components act as the metal boundary of the cooking cavity, allowing them to reflect microwaves. When the multiple movable components are in a second position, they separate to expose the air inlet, and the shell assembly corresponding to the air inlet reflects the microwaves. Because the cooking appliance uses multiple movable components and drives them to switch between the first and second positions, the metal boundary of the cooking cavity can be changed, allowing microwaves in the cooking cavity to be reflected along different paths, thereby improving the uniformity of microwave distribution within the cooking cavity.

[0028] In one embodiment of the present invention, the cooking appliance further includes a second driving component, which is connected to a plurality of movable parts and is capable of driving the plurality of movable parts to switch between a first position and a second position.

[0029] In this technical solution, the cooking appliance also includes a second driving component, which can drive multiple moving parts to switch between a first position and a second position, thereby realizing the stirring of microwaves in the cooking cavity.

[0030] In one embodiment of the present invention, the second drive assembly includes a second motor, a first transmission component, and a second transmission component; the first transmission component is connected to the second motor; the second transmission component cooperates with the first transmission component and is connected to a plurality of moving components.

[0031] In this technical solution, the second motor transmits power to multiple moving parts through the first transmission component and the second transmission component, thereby driving the multiple moving parts.

[0032] Specifically, the first transmission component includes a first gear, and the second transmission component includes multiple second gears. The multiple second gears are respectively connected to multiple moving parts and mesh with the first gear, thereby realizing the transmission of power.

[0033] The second drive assembly also includes a second connecting shaft, and a movable part is sleeved on the second connecting shaft, which can rotate with the second connecting shaft.

[0034] There are four moving parts, and the edges where the four moving parts contact each other are arc-shaped, matching the movement trajectory of the four moving parts. The four moving parts form a circular baffle, which can be opened or closed under the drive of a second motor, thus forming a structure similar to an aperture, so as to change the metal boundary of the cooking cavity during the opening or closing process.

[0035] The four moving parts have three positions during movement. In the first position, all four moving parts are in contact, with multiple parts in the first position and the baffle closed. In the second position, all four moving parts are fully open, with multiple parts in the second position. In the third position, the moving parts are positioned between the first and second positions, with the baffle partially open. The baffle can also be kept in motion by a second motor, and can switch between the first, second, and third positions.

[0036] In one technical solution of the present invention, the shell assembly includes a first shell and a partition. The first shell is provided with a mounting groove recessed in the direction away from the cooking cavity. The partition is provided with an air inlet and covers the mounting groove. The fan assembly includes a third motor and a fan blade. The fan blade is disposed in the mounting groove and the third motor is connected to the fan blade.

[0037] In this technical solution, the shell assembly includes a first shell, which is provided with a mounting groove recessed in the direction away from the cooking cavity. The fan blade is disposed in the mounting groove. While realizing the installation of the mounting groove, the fan blade is prevented from occupying the space inside the cooking cavity, thereby increasing the volume inside the cooking cavity and allowing more food to be placed inside the cooking cavity.

[0038] The housing assembly also includes a partition that covers the mounting slot, preventing food or debris from entering the mounting slot and thus ensuring smoother fan blade rotation. An air inlet is provided on the partition, allowing air generated by the fan to enter the cooking cavity.

[0039] Specifically, when the baffle includes multiple movable parts and the multiple movable parts are in the second position, the inner wall of the mounting groove serves as the metal boundary of the cooking cavity.

[0040] The first housing includes a rear wall, and a mounting groove is disposed on the rear wall of the first housing.

[0041] In one embodiment of the present invention, the cooking appliance further includes a heating element disposed in a mounting groove and arranged around the fan blades.

[0042] In this technical solution, the cooking appliance also includes a heating element, which is disposed within a mounting slot to avoid occupying space within the cooking cavity, thereby increasing the volume of the cooking cavity and allowing more food to be placed inside. The heating element is arranged around the circumference of the fan blades, enabling better contact between the heating element and the air blown out by the fan blades, thus improving the heating effect of the heating element on the air entering the cooking cavity.

[0043] In one technical solution of the present invention, there are multiple baffles arranged side by side and distributed on the same side wall of the cooking cavity.

[0044] In this technical solution, there are multiple baffles arranged in parallel, which allows the baffles to better stir the microwaves and further improve the uniformity of microwave distribution in the cooking cavity.

[0045] Specifically, the baffle can be located on the left or right side wall of the cooking cavity, and the first drive assembly drives the baffle to reciprocate left and right. The baffle can also be located on the bottom or top wall of the cooking cavity, and the first drive assembly drives the baffle to reciprocate up and down. The baffle can also be located on the rear wall of the cooking cavity, and the first drive assembly drives the baffle to reciprocate back and forth.

[0046] In one technical solution of the present invention, there are multiple first driving components, and the multiple first driving components are respectively connected to multiple baffles.

[0047] In this technical solution, when there are multiple baffles, the multiple baffles can be set on different inner walls of the cooking cavity, but it is necessary to ensure that the movement paths of the baffles on different inner walls do not overlap, so as to avoid interference between the multiple baffles during movement.

[0048] In one technical solution of the present invention, there are multiple first driving components, and the multiple first driving components are respectively connected to multiple baffles.

[0049] In this technical solution, there are multiple first drive components, which can drive multiple baffles to move respectively, thereby enabling more flexible control of the baffle movement and enriching the control scheme of the baffles.

[0050] Specifically, multiple baffles can simultaneously move away from or near the inner wall of the cooking cavity under the drive of multiple first drive components, or they can alternately move away from or near the inner wall of the cooking cavity.

[0051] In one technical solution of the present invention, the baffle is a flexible metal baffle or a shape memory metal baffle.

[0052] In this technical solution, the baffle is a flexible metal baffle or a shape memory metal baffle, which eliminates the need for a driving component. The baffle can change the boundary of the microwave field inside the cooking cavity by changing its own shape, thereby simplifying the structure of the cooking appliance.

[0053] Specifically, the concave-convex state of the cooking cavity can be adjusted by using flexible metal baffles or memory metal baffles to change the metal boundary of the cooking cavity.

[0054] In one technical solution of the present invention, the stroke of the baffle is greater than or equal to 1 mm and less than or equal to 80 mm.

[0055] In this technical solution, the travel of the baffle is greater than or equal to 1 mm and less than or equal to 80 mm, which can ensure the stirring effect of microwaves while avoiding excessive travel of the baffle that would affect the effective volume of the cooking cavity.

[0056] In one technical solution of the present invention, the shell assembly further includes a waveguide port disposed on the first side wall of the cooking cavity; the baffle is opposite to the second side wall of the cooking cavity; the first side wall and the second side wall are different side walls of the cooking cavity.

[0057] In this technical solution, the waveguide port is located on the first side wall of the cooking cavity; the baffle is opposite to the second side wall of the cooking cavity. The first side wall and the second side wall are different side walls of the cooking cavity, so that the microwaves entering the cooking cavity from the waveguide port can propagate to the baffle, thereby enabling the baffle to better stir the microwaves and improve the uniformity of the microwaves in the cooking cavity.

[0058] Specifically, the waveguide port and the baffle are located on different side walls. After the microwaves enter the cooking cavity through the waveguide port, they will first propagate to the baffle, which will then refract the microwaves before they propagate in the cooking cavity, thereby improving the stirring effect of the baffle on the microwaves.

[0059] In one embodiment of the present invention, the cooking appliance further includes a microwave emitting component and a waveguide; the microwave emitting component is connected to the shell component; the waveguide is disposed on the shell component and extends from the microwave emitting component to the waveguide port.

[0060] In this technical solution, a waveguide is provided on the shell assembly. The waveguide can guide the microwaves emitted by the microwave emitting assembly to the waveguide port, so that the microwaves can enter the cooking cavity to heat the food.

[0061] In one embodiment of the present invention, the baffle is circular. The baffle may also be polygonal, such as a square, rectangle, triangle, or hexagon.

[0062] In one embodiment of the present invention, the shell assembly includes a first shell and a second shell, the first shell having a cooking cavity, and the second shell being fitted over the outside of the first shell.

[0063] The mounting slot is located on the thick wall of the first housing and protrudes from the thick wall of the first housing in a direction away from the cooking cavity, thereby preventing components such as fan blades and heating elements from occupying space inside the cooking cavity.

[0064] In one technical solution of the present invention, a turntable can be provided inside the first housing, which can drive the food to rotate, thereby further improving the uniformity of the food being heated in the cooking cavity.

[0065] The turntable can be omitted from the first housing, reducing its footprint within the cooking cavity and allowing for a larger food placement area at the bottom. This enables the cooking appliance to hold more food, thus improving its overall quality. Eliminating the turntable also simplifies the appliance's structure, resulting in a smoother inner wall for easier cleaning and reducing the difficulty of cleaning the cooking cavity.

[0083] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0084] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0085] The following reference Figures 1 to 13 A cooking appliance is described according to some embodiments of the present invention.

[0086] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a cooking utensil is provided, including a shell assembly 100 and a baffle 200; as Figure 2 and Figure 3 As shown, the shell assembly 100 is provided with a cooking cavity 110; the baffle 200 is disposed in the cooking cavity 110 and is movable within the cooking cavity 110 to change the boundary of the cooking cavity 110 when the cooking appliance is in operation.

[0087] In this embodiment, the cooking appliance includes a shell assembly 100, within which a cooking cavity 110 is provided. The cooking cavity 110 can hold food ingredients for cooking. The cooking appliance also includes a baffle 200, which is movable within the cooking cavity 110, thereby altering the boundaries of the cooking cavity 110. Because the baffle 200 can alter the boundaries of the cooking cavity 110, when the cooking appliance cooks the food using microwaves, it can change the boundaries of the microwave field within the cooking cavity 110. When microwaves propagate to the boundary of the cooking cavity 110, they are reflected in different directions as the baffle 200 moves, thus changing the microwave propagation path within the cooking cavity 110, i.e., changing the distribution state of the microwaves within the cooking cavity 110. Furthermore, the microwave propagation path changes with the movement of the baffle 200, improving the stirring effect of the microwaves and making the microwave distribution within the cooking cavity 110 more uniform.

[0088] Because the cooking appliance moves the baffle 200, the microwaves are distributed more evenly in the cooking cavity 110, thereby heating more areas of the food and improving the uniformity of heating the food by the cooking appliance.

[0089] Furthermore, the cooking appliance improves the uniformity of microwave distribution within the cooking cavity 110 by driving the baffle 200 to move. This eliminates the need for a turntable structure, reducing its footprint within the cooking cavity 110 and allowing for a larger food placement area at the bottom of the cavity. This enables the cooking appliance to hold more food, thus improving its overall quality. Eliminating the turntable structure also simplifies the appliance's design, resulting in a smoother inner wall for the cooking cavity 110, making cleaning easier and reducing the difficulty of cleaning the cavity.

[0090] The cooking appliance changes the boundary of the cooking cavity 110 by using the baffle 200, which makes the structure required to change the boundary of the cooking cavity 110 simpler and the cost required to change the boundary of the cooking cavity 110 lower. As a result, the cooking appliance does not have to add too many complex structures to improve the uniformity of microwave distribution, nor does it have to add too much cost to improve the uniformity of microwave distribution, making the cooking appliance more practical.

[0091] Furthermore, the cooking appliance changes the boundary of the cooking cavity 110 through the baffle 200 without altering the structure of the original shell assembly 100, thus preventing microwave leakage due to the change in the boundary of the cooking cavity 110 and ensuring the safety of the cooking appliance during operation.

[0092] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0093] like Figure 4 As shown, the shell assembly 100 is provided with an air inlet 120, and the cooking appliance also includes a fan assembly 300, which is located at the air inlet 120 and can deliver air into the cooking cavity 110; the baffle 200 is arranged opposite to the air inlet 120.

[0094] In this embodiment, the shell assembly 100 is provided with an air inlet 120, and a fan assembly 300 is provided at a position opposite to the air inlet 120 on the shell assembly 100. The fan assembly 300 can deliver air into the cooking cavity 110 to bake the food. A baffle 200 is provided at the air inlet 120. The baffle 200 can prevent food or debris from entering the air outlet, thereby making it easier for the user to clean the cooking cavity 110.

[0095] Since the baffle 200 can change the boundary of the cooking cavity 110 and also block food or debris from entering the air outlet, the baffle 200 has a wider range of functions, thereby simplifying the structure of the cooking appliance and reducing the cost of the cooking appliance.

[0096] Furthermore, the baffle 200 is positioned opposite the air inlet 120, causing the airflow to be turbulent after exiting the air inlet 120. This allows the air to flow more evenly to all parts of the cooking cavity 110, further improving the uniformity of heating the food. In other words, by placing the baffle 200 at the air inlet 120 of the cooking cavity 110 and driving the baffle 200 to move, both the microwaves and the air entering the cooking cavity 110 can be distributed more evenly, thus improving the uniformity of heating the food.

[0097] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0098] like Figure 5 , Figure 6 and Figure 7 As shown, the cooking appliance also includes a first drive assembly 400, which is connected to the baffle 200 to drive the baffle 200 to move closer to or away from the air inlet 120.

[0099] In this embodiment, the first driving component 400 drives the baffle 200 to move closer to or further away from the air inlet 120, so that the baffle 200 can reciprocate relative to the air inlet 120, thereby enabling the baffle 200 to periodically reflect microwaves to different paths, and the microwaves are more evenly distributed in the cooking cavity 110.

[0100] like Figure 1 As shown, the first drive assembly 400 drives the baffle 200 closer to the air inlet 120, that is, the first drive assembly 400 drives the baffle 200 to move towards the air inlet 120, causing the boundary of the cooking cavity 110 to also move towards the air inlet 120. Figure 8 As shown, the first drive assembly 400 drives the baffle 200 away from the air inlet 120, that is, the first drive assembly 400 drives the baffle 200 to move away from the air inlet 120, so that the boundary of the cooking cavity 110 also moves away from the air inlet 120.

[0101] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0102] The first drive assembly 400 includes a support component, a first connecting shaft, and a first motor; the support component is provided with an internal thread; the first connecting shaft passes through the support component and cooperates with the internal thread, and the first end of the first connecting shaft is connected to the baffle 200; the first motor is connected to the second end of the first connecting shaft.

[0103] In this embodiment, the first drive assembly 400 includes a first connecting shaft and a first motor. A first end of the first connecting shaft is connected to the baffle 200, and a second end of the first connecting shaft is connected to the first motor. The first connecting shaft has an external thread, which engages with the internal thread of the support component. When the first motor drives the first connecting shaft to rotate, the first connecting shaft can move axially under the action of the support component, thereby driving the baffle 200 and allowing the baffle 200 to move away from or closer to the air inlet 120.

[0104] Specifically, the second end of the first connecting shaft is cylindrical and sleeved on the output shaft of the first motor. The first connecting shaft and the output shaft of the first motor are keyed together, so that the first motor can drive the first connecting shaft to rotate and the first connecting shaft can also move along the axial direction, thereby driving the baffle 200.

[0105] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0106] The first drive assembly 400 includes a telescopic component, which includes a telescopic shaft connected to the baffle 200.

[0107] In this embodiment, the first drive component 400 includes a telescopic component, the telescopic shaft of which is telescopic and connectable to the baffle 200 to drive the baffle 200, so that the baffle 200 can move away from or closer to the air inlet 120.

[0108] Specifically, the telescopic component can be an electric telescopic rod or a motor with a telescopic output shaft.

[0109] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0110] like Figure 9 and Figure 10 As shown, the baffle 200 includes a plurality of movable parts 210, which are arranged adjacent to the inner wall of the cooking cavity 110. The plurality of movable parts 210 have a first position and a second position. When the plurality of movable parts 210 are in the first position, they are in contact with each other to block the air inlet 120. When the plurality of movable parts 210 are in the second position, they are separated to expose the air inlet 120.

[0111] In this embodiment, the baffle 200 includes multiple movable parts 210. When the multiple movable parts 210 are in a first position, they are in contact to block the air inlet 120. The multiple movable parts 210 serve as the metal boundary of the cooking cavity 110, thereby enabling them to reflect microwaves. When the multiple movable parts 210 are in a second position, they are separated to expose the air inlet 120, and the shell assembly 100 corresponding to the air inlet 120 reflects microwaves. Because the cooking appliance has multiple movable parts 210 and drives them to switch between the first and second positions, the metal boundary of the cooking cavity 110 can be changed, allowing microwaves from the cooking cavity 110 to be reflected along different paths, thereby improving the uniformity of microwave distribution within the cooking cavity 110.

[0112] Multiple movable parts 210 are arranged near the inner wall of the cooking cavity 110, that is, multiple movable parts 210 are close to the inner wall of the cooking cavity 110, and multiple movable parts 210 are at a certain distance from the inner wall of the cooking cavity 110.

[0113] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0114] like Figure 9 and Figure 10 As shown, the cooking appliance also includes a second drive assembly, which is connected to a plurality of movable parts 210 and is capable of driving the plurality of movable parts 210 to switch between a first position and a second position.

[0115] In this embodiment, the cooking appliance also includes a second driving component, which can drive multiple movable parts 210 to switch between a first position and a second position, thereby realizing the stirring of microwaves in the cooking cavity 110.

[0116] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0117] The second drive assembly includes a second motor, a first transmission component, and a second transmission component; the first transmission component is connected to the second motor; the second transmission component cooperates with the first transmission component and is connected to a plurality of moving parts 210.

[0118] In this embodiment, the second motor transmits power to multiple moving parts 210 through the first transmission component and the second transmission component, thereby driving the multiple moving parts 210.

[0119] Specifically, the first transmission component includes a first gear, and the second transmission component includes multiple second gears. The multiple second gears are respectively connected to multiple movable components 210 and mesh with the first gear, thereby realizing the transmission of power.

[0120] The second drive assembly also includes a second connecting shaft, and a movable part 210 is sleeved on the second connecting shaft. The movable part 210 can rotate with the rotation of the second connecting shaft.

[0121] The four moving parts 210 have three positions during operation. For example... Figure 11 As shown, in the first gear position, four movable parts 210 are in contact, multiple movable parts 210 are in the first position, and the baffle 200 is in the closed state, as shown. Figure 12 As shown, the second position is the state where all four movable parts 210 are fully open, and multiple movable parts 210 are in the second position. Figure 13 As shown, the third position is when the movable part 210 is in the third position, which is between the first and second positions, and the baffle 200 is in a half-open state. The baffle 200 can also be kept moving under the action of the second motor, and can switch between the first, second and third positions.

[0122] The four movable parts 210 have three positions during movement. In the first position, all four movable parts 210 are in contact, and the baffle 200 is in a closed state. In the second position, all four movable parts 210 are fully open. In the third position, the movable parts 210 are positioned between the first and second positions, and the baffle 200 is in a half-open state. The baffle 200 can also be kept in motion by the second motor, and can switch between the first, second, and third positions.

[0123] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0124] like Figure 4 As shown, the shell assembly 100 includes a first shell 130 and a partition 140. The first shell 130 is provided with a mounting groove 150 recessed in the direction away from the cooking cavity 110. The partition 140 is provided with an air inlet 120 and covers the mounting groove 150. The fan assembly 300 includes a third motor 310 and a fan blade 320. The fan blade 320 is disposed in the mounting groove 150, and the third motor 310 is connected to the fan blade 320.

[0125] In this embodiment, the shell assembly 100 includes a first shell 130, which is provided with a mounting groove 150 recessed in the direction away from the cooking cavity 110. The fan blade 320 is disposed in the mounting groove 150. While realizing the installation of the mounting groove 150, the fan blade 320 is prevented from occupying the space in the cooking cavity 110, thereby increasing the volume in the cooking cavity 110 and allowing more ingredients to be placed in the cooking cavity 110.

[0126] The housing assembly 100 also includes a partition 140, which covers the mounting groove 150 and prevents food or debris in the cooking cavity 110 from entering the mounting groove 150, thereby making the fan blades 320 rotate more smoothly. The partition 140 is provided with an air inlet 120, so that the air generated by the fan can enter the cooking cavity 110 through the air inlet 120.

[0127] Specifically, when the baffle 200 includes a plurality of movable parts 210 and the plurality of movable parts 210 are in the second position, the inner wall of the mounting groove 150 serves as the metal boundary of the cooking cavity 110.

[0128] The first drive assembly 400 is mounted on the partition 140.

[0129] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0130] like Figure 4 As shown, the cooking appliance also includes a heating element 500, which is disposed in the mounting groove 150 and arranged around the fan blade 320.

[0131] In this embodiment, the cooking appliance also includes a heating element 500, which is disposed within the mounting slot 150. This avoids the heating element 500 occupying space within the cooking cavity 110, thereby increasing the volume of the cooking cavity 110 and allowing more food to be placed within it. The heating element 500 is arranged around the circumference of the fan blade 320, enabling it to better contact the air blown out by the fan blade 320, thus improving the heating effect of the heating assembly on the air entering the cooking cavity 110.

[0132] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0133] like Figure 1 and Figure 2 As shown, there are multiple baffles 200, which are arranged side by side and distributed on the same side wall of the cooking cavity 110.

[0134] In this embodiment, there are multiple baffles 200 arranged side by side, which allows the baffles 200 to better stir the microwaves and further improve the uniformity of microwave distribution in the cooking cavity 110.

[0135] Specifically, the baffle 200 can be disposed on the left side wall or the right side wall of the cooking cavity 110, and the first drive assembly 400 drives the baffle 200 to reciprocate left and right. The baffle 200 can also be disposed on the bottom wall or the top wall of the cooking cavity 110, and the first drive assembly 400 drives the baffle 200 to reciprocate up and down. The baffle 200 can also be disposed on the rear wall 132 of the cooking cavity 110, and the first drive assembly 400 drives the baffle 200 to reciprocate back and forth.

[0136] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0137] There are multiple first drive components 400, and each of the multiple first drive components 400 is connected to a multiple baffles 200.

[0138] In this embodiment, when there are multiple baffles 200, the multiple baffles 200 can be respectively set on different inner walls of the cooking cavity 110, but it is necessary to ensure that the movement paths of the baffles 200 on different inner walls do not overlap, so as to avoid interference between the multiple baffles 200 during movement.

[0139] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0140] There are multiple first drive components 400, and each of the multiple first drive components 400 is connected to a multiple baffles 200.

[0141] In this technical solution, there are multiple first drive components 400, which can drive multiple baffles 200 to move respectively, thereby enabling more flexible control of the movement of the baffles 200 and enriching the control scheme of the baffles 200.

[0142] Specifically, the multiple baffles 200 can simultaneously move away from or towards the inner wall of the cooking cavity 110 under the drive of the multiple first drive components 400, or they can alternately move away from or towards the inner wall of the cooking cavity 110.

[0143] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0144] The baffle 200 is a flexible metal baffle 200 or a shape memory metal baffle 200.

[0145] In this embodiment, the baffle 200 is a flexible metal baffle 200 or a shape memory metal baffle 200, so that the baffle 200 does not need to be driven by a driving component. The baffle 200 can change the boundary of the microwave field in the cooking cavity 110 by changing its own shape, thereby simplifying the structure of the cooking appliance.

[0146] Specifically, the concave-convex state of the cooking cavity 110 can be adjusted by the flexible metal baffle 200 or the memory metal baffle 200 to change the metal boundary of the cooking cavity 110.

[0147] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0148] The stroke of baffle 200 is greater than or equal to 1 mm and less than or equal to 80 mm.

[0149] In this embodiment, the stroke of the baffle 200 is greater than or equal to 1 mm and less than or equal to 80 mm, which can ensure the stirring effect of microwaves while avoiding excessive stroke of the baffle 200 that would affect the effective volume of the cooking cavity 110.

[0150] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0151] The shell assembly 100 also includes a waveguide port disposed on the first side wall of the cooking cavity 110; the baffle 200 is opposite to the second side wall of the cooking cavity 110; the first side wall and the second side wall are different side walls of the cooking cavity 110.

[0152] In this embodiment, the waveguide port is disposed on the first side wall of the cooking cavity 110; the baffle 200 is opposite to the second side wall of the cooking cavity 110. The first side wall and the second side wall are different side walls of the cooking cavity 110, so that the microwaves entering the cooking cavity 110 from the waveguide port can propagate to the baffle 200, thereby enabling the baffle 200 to better stir the microwaves and improve the uniformity of the microwaves in the cooking cavity 110.

[0153] Specifically, the waveguide port and the baffle 200 are located on different side walls. After the microwave enters the cooking cavity 110 through the waveguide port, it will first propagate to the baffle 200, so that the baffle 200 can first refract the microwave before it propagates in the cooking cavity 110, thereby improving the stirring effect of the baffle 200 on the microwave.

[0154] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0155] The cooking appliance also includes a microwave emitting component and a waveguide; the microwave emitting component is connected to the housing component 100; the waveguide is disposed on the housing component 100 and extends from the microwave emitting component to the waveguide opening.

[0156] In this embodiment, a waveguide is provided on the shell assembly 100. The waveguide can guide the microwaves emitted by the microwave emitting assembly to the waveguide port, so that the microwaves can enter the cooking cavity 110 to heat the food.

[0157] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0158] The baffle 200 is circular in shape. The baffle 200 may also be polygonal, such as square, rectangle, triangle or hexagon.

[0159] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0160] The shell assembly 100 also includes a second shell, the first shell 130 is provided with a cooking cavity 110, and the second shell is fitted over the outside of the first shell 130.

[0161] The mounting groove 150 is disposed on the thick wall of the first housing 130 and protrudes from the thick wall of the first housing 130 in a direction away from the cooking cavity 110, thereby preventing components such as the fan blade 320 and the heating element 500 from occupying the space inside the cooking cavity 110.

[0162] like Figure 4 As shown, the housing assembly 100 also includes a rear cover plate 160, which covers the rear wall 132 of the first housing 130.

[0163] This embodiment provides a cooking appliance, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0164] A turntable can be installed inside the first housing 130. The turntable can drive the food to rotate, further improving the uniformity of the food being heated in the cooking cavity 110.

[0165] The turntable can also be omitted from the first housing 130, reducing the space occupied by the turntable structure within the cooking cavity 110 and allowing for a larger food placement area at the bottom of the cooking cavity 110. This enables the cooking appliance to hold more food, thereby improving its quality. Eliminating the turntable structure also simplifies the appliance's design, resulting in a smoother inner wall for the cooking cavity 110, making it easier for users to clean and effectively reducing the difficulty of cleaning the cooking cavity 110.

[0166] This embodiment provides a cooking appliance, including a shell assembly 100 and a baffle 200; the baffle 200 may be a plate-like structure and can move within the cooking cavity 110, thereby changing the boundary of the microwave field within the cooking cavity 110.

[0167] The baffle 200 may also include multiple movable parts 210, which have a first position and a second position. When the multiple movable parts 210 are in the first position, they are in contact with each other to block the air inlet 120, and the baffle 200 serves as the boundary of the microwave field inside the cooking cavity 110. When the multiple movable parts 210 are in the second position, they are separated to expose the air inlet 120, and the first housing 130 corresponding to the air inlet 120 serves as the boundary of the microwave field inside the cooking cavity 110, thereby changing the boundary of the microwave field inside the cooking cavity 110.

[0168] Since the baffle 200 can change the boundary of the microwave field in the cooking cavity 110, it can change the microwave propagation path in the cooking cavity 110, that is, change the distribution state of microwaves in the cooking cavity 110. Furthermore, the microwave propagation path will change with the movement of the baffle 200, thereby improving the stirring effect of microwaves and making the distribution of microwaves in the cooking cavity 110 more uniform.

[0169] Because the cooking appliance moves the baffle 200, the microwaves are distributed more evenly in the cooking cavity 110, thereby heating more areas of the food and improving the uniformity of heating the food by the cooking appliance.
