Description

Technical Field

[0001] The utility model relates to the technical field of microwave ovens, in particular to a microwave oven with an air frying function. Background Art

[0002] With the continuous improvement of living standards, consumers' demand for diversified food cooking methods is also increasing. Coupled with the limited kitchen operation space, kitchen appliances with only a single function will be difficult to meet the needs of consumers due to occupying a large amount of space. For most consumers, microwave ovens and air fryers are both commonly used kitchen appliances. However, the functions of these two are independent of each other and each occupies a large amount of kitchen space. Therefore, an air fry microwave integrated machine with both the functions of a microwave oven and an air fryer has a large market prospect.

[0003] However, the food processing principles of microwave ovens and air fryers are different. Among them, a microwave oven establishes a microwave electric field in the oven cavity and uses the food to absorb microwave energy in the microwave electric field to heat itself, while an air fryer uses a hot air fan to blow the air heated by a heating device to form a hot air circulation in the food cooking chamber, continuously taking away the moisture on the surface of the food and baking the inside of the food, so as to make the food have a crispy outside and tender inside fried texture. Therefore, a microwave oven with both the functions of a microwave oven and an oven also needs to consider the differences in the two food processing principles.

[0004] In the prior art, microwave ovens with an air frying function are mostly based on the structure of traditional microwave ovens, and the function superposition of microwave heating and air frying heating is realized by adding an air frying component on the top or side of the microwave oven.

[0051] The following combines the attached Figures 1 to 7 And further illustrates the technical solutions of the present utility model through specific implementation manners.

[0052] A microwave oven with an air fry function, comprising a housing, a furnace body 10, a door assembly 70, a microwave assembly 2 and a hot air assembly;

[0053] The hot air assembly includes a heating element 41, a fan 42 and a fan motor 44;

[0054] An inner part of the furnace body 10 forms a cooking cavity 101 for accommodating food, and the door assembly 70 is disposed on the front side of the furnace body 10 in an openable and closable manner;

[0055] The microwave assembly 2 is located on any one side of the left, right or rear side of the furnace body 10;

[0056] A hot air cavity 102 is formed at the top of the furnace body 10, and a plurality of air holes 110 are formed in the top of the furnace body 10. The cooking cavity 101 and the hot air cavity 102 are communicated through the air holes 110;

[0057] The heating element 41 and the fan 42 are disposed in the hot air cavity 102. The fan motor 44 drives the fan 42 to rotate through a transmission assembly, and a motor shaft 441 of the fan motor 44 is arranged non-coaxially with a rotating shaft 421 of the fan 42.

[0058] Reference Figures 1 to 7 , the present utility model provides a microwave oven with an air fry function, comprising a furnace body 10, a door assembly 70, a microwave assembly 2 and a hot air assembly composed of a heating element 41, a fan 42 and a fan motor 44.

[0059] The microwave assembly 2 is located on any one side of the left, right or rear side of the furnace body 10, and is used for generating microwaves and transmitting them into the cooking cavity 101 to realize microwave cooking of food.

[0060] A hot air cavity 102 is formed at the top of the furnace body 10, and the heating element 41 and the fan 42 are arranged inside the hot air cavity 102. The air in the cavity is heated by the heating element 41, and the hot air is blown into the cooking cavity 101 by driving the fan 42 to rotate by the fan motor 43, so as to realize air fry cooking. Further explanation, the fan motor 44 that drives the fan 42 to rotate is arranged non-coaxially. By horizontally distributing the fan motor 44 and the fan 42 instead of the traditional vertically stacked arrangement, the overall height of the microwave oven is significantly reduced, making the device more compact in the vertical direction and more adaptable to the height of common kitchen cabinets in modern kitchens, so that users can more conveniently place it on the kitchen countertop.

[0061] Compared with traditional microwave ovens that have the microwave component 2 designed at the bottom or the top, by arranging the microwave component 2 on the side of the oven body 10 and removing structures such as the isolation plate and turntable at the bottom, the accommodation space of the cooking cavity 101 in the vertical direction is effectively guaranteed, the observable range inside the cooking cavity 101 can be increased, and at the same time, the requirement for miniaturization of the device is met. In addition, by arranging the air fry component on the top of the oven body 10, the microwave oven product has two cooking modes, meeting the diverse cooking requirements of users; and the hot air component and the microwave component 2 are physically separated in space, making the two functional modules more independent and not affecting each other. This setting also makes the overall structure of the microwave oven more compact, effectively reducing the volume of the overall device and saving kitchen space. Further explanation, the fan motor 44 of the hot air component and the hot air cavity 102 (fan 42 and heating element 41) are horizontally distributed, making the overall device more compact and more beautiful. In addition, since the fan motor 44 is not directly above the heating element 41, the influence of heat on the fan motor 44 is further reduced, the service life of the fan motor 44 can be improved, and the maintenance cost can be reduced.

[0062] Furthermore, an installation cavity is formed by enclosing the outer side of the housing and the oven body 10. The installation cavity includes an upper installation cavity and a side installation cavity. The upper installation cavity is formed by enclosing the housing and the top wall of the oven body 10, and the side installation cavity is formed by enclosing the housing and the side wall of the oven body 10;

[0063] The hot air cavity 102 is arranged in the upper installation cavity;

[0064] The hot air component is arranged in the upper installation cavity, or a part of the hot air component is arranged in the upper installation cavity and another part is arranged in the upper part of the side installation cavity.

[0065] Even further, it further includes a hot air cover 43. The hot air cavity 102 is formed by covering the upper part of the oven body 10 with the hot air cover 43;

[0066] The fan 42 is arranged to rotate inside the hot air cover 43. One end of the rotating shaft 421 of the fan 42 penetrates through the hot air cover 43 and is driven by the fan motor 44 through a transmission component;

[0067] The fan motor 44 is arranged outside the hot air cover 43 and is on the same outer side of the oven body as the microwave component 2.

[0068] Even further, the transmission component is a belt transmission component;

[0069] The belt drive assembly includes a first pulley 451, a second pulley 452 and a belt 453. The first pulley 451 is installed on the rotating shaft 421. The first pulley 451 is located above the hot air hood 43. The second pulley 452 is installed on the motor shaft 441 of the fan motor 44. The belt 453 is sleeved between the first pulley 451 and the second pulley 452.

[0070] When the microwave oven is working, the fan motor 44 works, and the motor shaft 441 drives the second pulley 452 to rotate. Driven by the belt 453, the first pulley 451 rotates and drives the fan 42 to rotate through the rotating shaft 421, so that the air in the cooking cavity 101 moves upward and enters the hot air cavity 102 through the air hole 110. The air is heated by the heating element 41 in the hot air cavity 102 and re-enters the cooking cavity 101 through the air hole 110 to cook the food in the cooking cavity 101.

[0071] The transmission mode of the belt drive assembly makes the fan motor 44 and the fan 42 relatively independent in physical position, which makes the internal layout of the microwave oven more flexible and can further optimize the space utilization of the equipment, which is particularly important for modern kitchen appliances that require compact design.

[0072] To further illustrate, the first pulley 451 is arranged above the hot air hood 43 but not inside the hot air chamber 102. The first pulley 451 and the second pulley 452 are connected through a belt 453 and are located outside the hot air chamber 102, thereby ensuring the hot air circulation effect inside the hot air chamber 102 and facilitating repair and maintenance.

[0073] On the other hand, by using the belt drive assembly as the transmission structure, it is convenient to adjust the rotation speed of the fan 42 by adjusting the tension of the belt 453, thereby achieving precise control of the hot air circulation during the cooking process.

[0074] Optionally, the first pulley 451 and the second pulley 452 are made of the same material, and when rotating, the friction coefficients of the first pulley 451 and the second pulley 452 are the same, so that the performance of the belt transmission assembly is stable.

[0075] Furthermore, the fan motor 44 includes a fan motor body and the motor shaft 441, and the fan motor body is located below the transmission assembly;

[0076] An extension portion 431 is provided on one side of the hot air cover 43 or the upper portion of the furnace body 10 close to the fan motor 44, and the extension portion 431 is provided with a mounting portion;

[0077] The fan motor 44 further includes a motor base 442, the fan motor body is installed on the motor base 442, and the motor base 442 is fixedly installed with the hot air hood 43 or the upper part of the furnace body 10 through a mounting member passing through the mounting portion.

[0078] On one side of the hot air hood 43 close to the fan motor 44, there is an extension portion 431, and the extension portion 431 is provided with a mounting portion;

[0079] The fan motor 44 further includes a motor base 442, the fan motor body is installed on the motor base 442, and the motor base 442 is fixedly installed with the hot air hood 43 through a mounting member passing through the mounting portion.

[0080] The extension portion 431 is located on the side of the hot air hood 43. The fan motor 44 is installed and connected to the hot air hood 43 (the extension portion 431 thereof) or the furnace body 10 through the motor base 442. The setting of the extension portion 431, on the one hand, makes the installation position of the fan motor body more reasonable, enables the fan motor body to closely fit with the hot air hood 43, reduces unnecessary space occupation, and makes the internal space layout of the microwave oven more compact and efficient; on the other hand, the motor base 442 is installed and connected to the extension portion through a fastener passing through the mounting hole, making the installation of the fan motor body more stable, and can ensure that the fan motor body will not shake or fall off during long-term operation or high-speed rotation, thus ensuring the overall stability and safety of the microwave oven.

[0081] Further, a cooling fan 5 is further included, the cooling fan 5 is installed on the motor shaft 441, and the cooling fan 5 is driven by the fan motor 44 through the motor shaft 441.

[0082] The installation of the cooling fan 5 on the motor shaft 441 makes full use of the existing structure and does not require additional occupation of the internal space of the microwave oven. By installing the cooling fan 5 on the motor shaft 441 and directly driving it by the fan motor 44, the heat dissipation effect of the microwave oven is significantly enhanced. This can not only effectively reduce the operating temperature of the fan motor 44 and extend its service life, but also ensure that other key components inside the microwave oven work at an appropriate temperature, guaranteeing the stability and reliability of the entire system.

[0083] Since the cooling fan 5 and the fan motor 44 share the same power source, there is no need for additional energy consumption. This not only simplifies the energy management of the device, but also helps to improve the energy utilization efficiency and reduce the overall energy consumption.

[0084] Even further, the heating element 41 is a ring-shaped heating tube, and the ring-shaped heating tube is installed and connected to the hot air hood 43 through a plurality of fixing members 46;

[0085] The ring-shaped heating tube is disposed around the outer periphery of the fan 42;

[0086] A plurality of the air holes 110 correspond to the positions of the heating element 41 and the fan 42.

[0087] The annular heating tube is installed and connected to the hot air hood 43 through a plurality of fixing members 46, so that the heating element 41 is firmly fixed on the hot air hood 43, avoiding faults and potential safety hazards caused by loosening or vibration.

[0088] The annular heating tube is arranged around the outer peripheral side of the fan 42, forming a good cooperation with the fan 42, so that the air heated on the outer peripheral side of the fan 42 can be transmitted to the cooking cavity 101 faster and more evenly, improving the uniformity and efficiency of air heating.

[0089] Preferably, the opening of the air holes 110 corresponds to the installation positions of the heating element 41 and the fan 42. When the microwave oven works, the fan motor 44 drives the fan 42 to rotate. Under the suction force generated by the rotation of the fan 42, the air in the cooking cavity 101 enters the upper hot air cavity 102 through the air holes 110 opened at the position corresponding to the fan 42; the heating element 41 continuously heats in the hot air cavity 102, and the heated air enters the lower cooking cavity 101 through the air holes 110 opened at the position corresponding to the heating element 41 to cook the food in the cooking cavity 101. The air in the cooking cavity 101 and the hot air cavity 102 continuously circulates up and down under the action of the fan 42, forming hot air convection, so as to perform air frying on the food.

[0090] Furthermore, the microwave component 2 includes a microwave generating sub-component 21 and a microwave stirring sub-component 22;

[0091] The microwave stirring sub-component 22 is arranged between the furnace body 10 and the microwave generating sub-component 21. The microwave stirring sub-component 22 is used for stirring and dispersing the microwaves generated by the microwave generating sub-component 21. The cooking cavity 101 is provided with a microwave input port 11 on the side wall facing the microwave stirring sub-component 22, and a splash-proof baffle 13 capable of penetrating microwaves is installed at the microwave input port 11.

[0092] By arranging the microwave generating sub-component 21 and the microwave stirring sub-component 22 on the side of the furnace body 10, and the microwave stirring sub-component 22 is located between the furnace body 10 and the microwave generating sub-component 21, the microwaves can be effectively stirred and dispersed, so that the microwaves are evenly distributed in the cooking cavity 101, which can not only improve the cooking efficiency, but also ensure that the food is evenly heated, avoiding problems such as local overheating or undercooking.

[0093] A microwave-penetrable splash guard 13 is installed at the microwave input port 11. The splash guard 13 can effectively prevent food from splashing out or soup from overflowing during cooking, which may damage the microwave generating sub-assembly 21 and the microwave stirring sub-assembly 22. This improves the safety of the microwave oven, helps extend its service life, and does not affect the transmission of microwaves into the cooking cavity 101.

[0094] Furthermore, the microwave generating sub-assembly 21 includes a high-voltage transformer, a high-voltage capacitor, a magnetron 211, and a waveguide box 212.

[0095] The waveguide box 212 is disposed below the cooling fan 5. The waveguide box 212 is installed and connected to the outer side of the furnace body 10, and a waveguide 103 is formed between the waveguide box 212 and the furnace body 10.

[0096] The high-voltage transformer, the high-voltage capacitor, and the magnetron 211 are disposed at one end of the waveguide box 212 away from the furnace body 10. The microwave generating part of the magnetron 211 communicates with the waveguide cavity 103.

[0097] The high-voltage transformer, the high-voltage capacitor, and the magnetron 211 are electrically connected respectively.

[0098] The microwave stirring sub-assembly 22 includes a stirring motor 221, stirring blades 222, and a stirring blade bracket 223.

[0099] The stirring blades 222 are disposed in the waveguide cavity 103. The stirring motor 221 is fixedly installed on the outer side of the waveguide box 212. The stirring blades 222 are connected to the stirring motor 221 through the stirring blade bracket 223, and the stirring motor 221 is used to drive the stirring blades 222 to rotate.

[0100] Setting the high-voltage transformer, the high-voltage capacitor, and the magnetron 211 at one end of the waveguide box 212 away from the furnace body 10 increases the distance between these components and the cooking cavity 101, reduces the potential damage to these components caused by high temperature or microwave leakage, and improves the safety of the microwave oven. The high-voltage transformer, the high-voltage capacitor, and the magnetron 211 are electrically connected respectively, constituting a complete microwave generating system. The high-voltage transformer provides a high-voltage power supply, the high-voltage capacitor is used to store energy, and the magnetron generates microwaves according to the input power signal. This design improves the energy utilization efficiency and makes the microwave generation more stable and efficient.

[0101] A waveguide cavity 103 is formed between the waveguide box 212 and the furnace body 10, and the microwave generating part of the magnetron 211 is directly connected to the waveguide cavity 103. The microwave generated by the magnetron 211 can directly enter the waveguide cavity 103 and then enter the cooking cavity 101 of the microwave oven, which helps to stably transmit the microwave, reduces the problems of microwave attenuation or uneven distribution caused by too long or complex transmission paths, ensures the transmission efficiency of the microwave, and reduces energy loss.

[0102] The stirring blade 222 rotates in the waveguide cavity 103 driven by the stirring motor 221, which can effectively stir and disperse the microwave, making the microwave more evenly distributed in the cooking cavity 101 of the microwave oven. This helps to eliminate the problem of uneven heating caused by uneven microwave energy distribution, ensures that the food is evenly heated during cooking, and improves the cooking effect. By the rotation of the stirring blade 222, a more complex reflection and refraction path of the microwave is formed inside the furnace body, thereby increasing the contact area and contact time between the microwave and the food. This helps the food to more fully absorb the microwave energy, improves the cooking efficiency, and shortens the cooking time.

[0103] Furthermore, the stirring motor 221 is fixedly arranged outside the waveguide box 212, and the stirring blade 222 is located in the waveguide cavity 25 and is connected to the stirring motor 221 through a stirring blade bracket 223. This design makes the structure of the microwave stirring subassembly 22 compact and easy to install. In addition, the stirring blade 222 and important components that generate microwaves such as the stirring motor 221, high-voltage transformer, high-voltage capacitor, and magnetron 211 are in different chambers (the waveguide box 212 plays a role of physical isolation), reducing the safety risk that the rotating stirring blade 222 affects the important components of the microwave generating subassembly 21, and further improving the safety of the microwave oven.

[0104] Since the waveguide box 212 is located below the cooling fan 5, the cooling fan 5 can effectively take away the heat generated by the microwave generating subassembly 21 and the microwave stirring subassembly 22, reduce their temperatures, thereby improving the working efficiency and stability of the microwave generating subassembly 21 and the microwave stirring subassembly 22.

[0105] Specifically, the working principle of the microwave generating subassembly 21 and the microwave stirring subassembly 22 is as follows: after being powered on, the high-voltage transformer and high-voltage capacitor (including high-voltage diode) work to generate high voltage to make the magnetron 211 work to generate microwaves, and the microwaves are introduced into the waveguide cavity 103 through the waveguide box 24; at the same time, the stirring motor 221 drives the stirring blade 222 to rotate through the stirring blade bracket 223, and the rotating stirring blade 222 disperses the microwaves in the waveguide cavity 103, so that the microwaves are evenly distributed in the cooking cavity 101, thereby making the food heated evenly.

[0106] Furthermore, the splash-proof baffle 13 is detachably installed at the microwave input port 11.

[0107] The microwave generating sub - assembly 21 and the microwave stirring sub - assembly 22 are key components in the microwave oven, and their working states directly affect the heating effect and performance of the microwave oven. By setting an opening on the side plate and equipping with a detachable splash - proof baffle 13, it is convenient for users to maintain, inspect, and clean the microwave generating sub - assembly 21 and the microwave stirring sub - assembly 22 without disassembling the entire microwave oven.

[0108] In addition, the setting of the baffle 13 can effectively prevent food from splashing out or soup from overflowing during cooking, which may damage the microwave generating sub - assembly 21 and the microwave stirring sub - assembly 22, thus improving the safety of the microwave oven and also helping to extend the service life of the microwave oven.

[0109] Furthermore, it also includes a fryer 60 with an open top. On both sides of the inner top of the cooking cavity 101, there are slide rails 14 extending along the depth direction of the cooking cavity 101, and the two slide rails 14 are used to support the fryer 60.

[0110] By setting the slide rails 14 on both sides of the top of the cooking cavity 101, the fryer 60 can be conveniently slid into and out of the cooking cavity 101 without the user having to lift and place the fryer 60 with great effort, improving the convenience of cooking. In addition, the design of the slide rails 14 makes the placement and removal of the fryer 60 more stable and safe, avoiding the risk of equipment damage or personal injury caused by improper operation.

[0111] Further explanation: Since the two slide rails 14 are located at the top of the cooking cavity 101, when the fryer 60 is supported and placed between the two slide rails 14, the fryer 60 is in the upper part of the cooking cavity 101, relatively close to the air - frying component. This makes the distance between the food placed in the fryer 60 and the air - frying component closer, and the efficiency of the circulating hot air acting on the food is higher. In addition, due to the combination of the air fryer and the microwave oven, users can adjust the cooking mode and temperature according to needs, achieving more refined cooking control.

[0112] Furthermore, the slide rail 14 includes a mounting part 141 and a supporting part 142;

[0113] The mounting part 141 is installed and connected to the top plate of the furnace body 10, and the supporting part 142 extends horizontally towards the inside of the cooking cavity 101, and the two supporting parts 142 on both sides support both sides of the fryer 60.

[0114] Such as Figure 4 and Figure 5As shown, the mounting connection design of the mounting portion 141 and the top plate 11 makes the installation and disassembly of the air fryer more convenient; the supporting portions 142 on both sides jointly support the two ends of the fryer 60, and the position of the air fryer inside the microwave oven is more stable, avoiding displacement or tipping due to vibration or improper operation during the cooking process, thereby ensuring the smooth cooking and the final quality of the food.

[0115] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
