For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0039] The following combines the attached Figures 1 to 6 and further illustrates the technical solution of the present utility model through specific embodiments.

[0040] As Figure 1 - Figure 6 shown, the present utility model provides a flat-panel microwave oven, which includes a housing 6, a cavity assembly 1, a door assembly 7, a microwave generating assembly 2, and a microwave stirring assembly 3. A cooking cavity 10 for accommodating food is formed inside the cavity assembly 1. The door assembly 7 is disposed on the cavity assembly 1 in an openable and closable manner, and the door assembly 7 is used to close the cooking cavity 10;

[0041] A mounting cavity is formed by enclosing the side wall of the furnace cavity assembly 1 and the outer shell 6. The microwave generating assembly 2 and the microwave stirring assembly 3 are arranged in the mounting cavity and are jointly located outside the same side wall of the furnace cavity assembly 1. The microwave stirring assembly 3 is arranged between the furnace cavity assembly 1 and the microwave generating assembly 2, and the microwave stirring assembly 3 is used for stirring and dispersing the microwave generated by the microwave generating assembly 2.

[0042] The furnace cavity assembly 1 is provided with a microwave inlet 11 on the side wall close to the microwave stirring assembly 3, and a splash-proof plate 12 capable of penetrating microwaves is installed at the microwave inlet 11.

[0043] The bottom plate of the cooking cavity is made of a non-glass or non-ceramic material.

[0044] In the flat microwave oven of the present application, since the microwave generating assembly 2 and the microwave stirring assembly 3 are arranged in the mounting cavity formed on the peripheral side of the furnace cavity assembly 1 instead of the traditional bottom, the bottom space in the microwave oven cavity is released, and there is no need to set an isolation plate and a turntable in the cooking cavity 10. Thus, the effective usable volume of the cooking cavity 10 of the microwave oven in the vertical direction is significantly increased, allowing users to place more or larger foods during cooking, or increasing the observable range inside the cooking cavity 10 (specifically, when the height inside the cooking cavity 10 is greater, it is more conducive to observing the inner cavity of the cooking cavity 10), facilitating users to observe the changes on the surface of the food during cooking, reducing the line of sight obstruction, and improving the practicality of the microwave oven. The setting of the microwave stirring assembly 3 between the furnace cavity assembly 1 and the microwave generating assembly 2 can effectively stir and disperse the microwave generated by the microwave generating assembly 2, and enter the cooking cavity 10 through the microwave inlet 11, making the microwave evenly distributed in the cooking cavity, helping to eliminate the problem of uneven heating caused by uneven microwave energy distribution, and improving the cooking effect of the food. A microwave-penetrable splash-proof plate 12 is installed at the microwave inlet 11, and the splash-proof plate 12 can effectively prevent food splashing or soup overflow during cooking from damaging the microwave generating assembly 2 and the microwave stirring assembly 3, thereby improving the safety of the microwave oven, helping to extend the service life of the microwave oven, and not affecting the transmission of microwaves into the cooking cavity 10 at the same time.

[0045] While maintaining the volume of the cooking cavity 10 of the microwave oven, the present application removes some structures at the bottom (such as the isolation plate and the turntable), making the overall structure of the microwave oven more compact, reducing the overall size of the microwave oven, and being more in line with the current trend of miniaturization of household appliances. This is not only convenient for users to place at home, but also reduces the cost of transportation and storage; in addition, since the isolation plate and turntable made of glass or ceramic are removed, the manufacturing cost of the microwave oven is effectively reduced. The removal of these structures not only reduces the material cost, but also simplifies the production process and improves production efficiency; finally, since there are no easily dirty parts such as turntables and isolation plates in the microwave oven cavity, cleaning becomes simpler and more convenient. At the same time, the microwave generating assembly 2 and the microwave stirring assembly 3 are located on the side, which also makes repair and maintenance easier.

[0046] In summary, the flat-panel microwave oven of the present application significantly improves the practicality, miniaturization, cost-effectiveness and cooking effect of the microwave oven by changing the positions of the microwave generating assembly 2 and the microwave stirring assembly 3, while also improving the convenience of cleaning and maintenance.

[0047] Furthermore, the bottom plate of the cooking cavity is made of metal, and the side wall of the oven cavity assembly is any one of the left side wall, the right side wall, and the rear side wall. By arranging the microwave generating assembly 2 and the microwave stirring assembly 3 on the left side, the right side, or the rear side of the oven cavity assembly 1, rather than the top or the bottom, the height and volume of the device can be further reduced, making the internal structure more compact. Preferably, the microwave generating assembly 2 and the microwave stirring assembly 3 are arranged on the left side or the right side of the oven cavity assembly 1, further reducing the thickness of the device and adapting to more different usage scenarios and customer needs.

[0048] Furthermore, the splash plate 12 is detachably mounted on the microwave inlet 11;

[0049] The splash plate 12 is made of non-glass material.

[0050] By providing an opening 11 on the side panel of the oven cavity assembly 1 close to the microwave generating assembly 2 and the microwave stirring assembly 3, and installing a removable splash-proof plate 12 at the opening 11, it is possible to effectively prevent food splashing or soup overflowing during cooking from damaging the microwave generating assembly 2 and the microwave stirring assembly 3, thereby improving the safety of the microwave oven and helping to extend the service life of the microwave oven.

[0051] To further explain, the splash guard 12 is designed to be detachable, which means that when the microwave generating assembly 2 and the microwave stirring assembly 3 need to be cleaned or repaired, the user can easily remove the splash guard 12. The splash guard 12 is arranged on the side, that is, it is installed vertically. The splash guard 12 in a vertical state is easier to disassemble than the isolation plate / splash guard in a horizontal state, thereby improving the maintenance convenience of the microwave oven.

[0052] Preferably, the splash guard 12 is made of a non - glass material. On the one hand, it reduces the manufacturing cost, and on the other hand, it also avoids the potential risk of glass explosion.

[0053] Furthermore, the side plates on both sides of the microwave inlet 11 are provided with clamping grooves 13, and both sides of the splash guard 12 are provided with convex parts. The convex parts on both sides are in one - to - one cooperation with the clamping grooves 13 on both sides.

[0054] On the side wall of the cooking cavity 10 facing the microwave stirring component 3, an installation concave cavity 15 extends outward. The open mouth of the installation concave cavity 15 is the microwave inlet 11, and the installation concave cavity 15 is used to install the microwave stirring component 3.

[0055] As Figure 5 shown, clamping grooves 13 are provided on the side plates on both sides of the microwave inlet 11, and convex parts are provided on both sides of the splash guard 12, so that the splash guard 12 can be quickly installed and disassembled through the cooperation of the convex parts and the clamping grooves 13, improving the operation convenience for users. The one - to - one cooperation between the convex parts and the clamping grooves 13 ensures the stability and firmness of the splash guard 12 after installation, preventing the splash guard from accidentally falling off or shifting during cooking, thus ensuring the safety and stability of the microwave oven during use.

[0056] Furthermore, the microwave generating component 2 includes a high - voltage transformer 21, a high - voltage capacitor 22, a magnetron 23, and a waveguide box 24.

[0057] The waveguide box 24 is arranged outside the furnace cavity component 1, and a waveguide cavity 25 is formed between the waveguide box 24 and the furnace cavity component 1.

[0058] The high - voltage transformer 21, the high - voltage capacitor 22, and the magnetron 23 are arranged outside the waveguide box 24 away from the furnace cavity component 1, and the microwave generating part of the magnetron 23 communicates with the waveguide cavity 25.

[0059] The high - voltage transformer 21, the high - voltage capacitor 22, and the magnetron 23 are electrically connected respectively.

[0060] The high-voltage transformer 21, high-voltage capacitor 22, and magnetron 23 are arranged at one end of the waveguide box 24 away from the oven cavity assembly 1, increasing the distance between them and the cooking cavity 10, reducing the potential damage to these components caused by high temperature or microwave leakage, and improving the safety of the microwave oven. The high-voltage transformer 21 is connected to the power supply of the microwave oven through a power cord to provide the required voltage; the output end of the high-voltage transformer 21 is connected to the magnetron 23 to provide the voltage required for the magnetron 23 to operate; the high-voltage capacitor 22 is connected to the magnetron 23 and the high-voltage transformer 21 respectively to optimize the generation and transmission of microwaves. By providing the waveguide box 24 and the waveguide cavity 25, and directly connecting the microwave generating part of the magnetron 23 to the waveguide cavity 25, the microwaves generated by the magnetron 23 can directly enter the waveguide cavity 25 and then enter the cooking cavity 10 of the microwave oven, which helps to stably transmit the microwaves, reduces the problems of microwave attenuation or uneven distribution caused by too long or complex transmission paths, ensures the transmission efficiency of the microwaves, and reduces energy loss.

[0061] Furthermore, the microwave stirring assembly 3 includes a motor 31 and a stirring blade 32;

[0062] The stirring blade 32 is arranged in the waveguide cavity 25, the motor 31 is arranged outside the waveguide box 24, the output end of the motor 31 is connected to the stirring blade 32, and the motor 31 is used to drive the stirring blade 32 to rotate;

[0063] The motor 31 and the magnetron 23 are located on the same side of the waveguide box 24, and the motor 31 and the magnetron 23 are horizontally distributed. The projections of the motor 31 and the magnetron 23 overlap in the horizontal direction. The projections of the motor 31 and the high-voltage transformer 21 overlap in the vertical direction. The projections of the magnetron 23 and the high-voltage transformer 21 do not overlap in the vertical direction, and the projections of the magnetron 23 and the high-voltage transformer 21 partially overlap in the horizontal direction.

[0064] The stirring blade 32 rotates in the waveguide cavity 25 driven by the motor 31, which can effectively stir and disperse the microwaves, making the microwaves more evenly distributed in the cooking cavity 10 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 32, the microwaves can be more widely transmitted in the waveguide cavity 25 and the cooking cavity 10, thereby improving the heating efficiency and heating speed of the microwave oven, helping to shorten the cooking time, and ensuring that the food reaches the ideal cooking effect in a short time.

[0065] To further illustrate, the motor 31 is arranged outside the waveguide box 24, and the stirring blade 32 is arranged inside the waveguide cavity 25. The stirring blade 32 and important components that generate microwaves such as the motor 31, the high-voltage transformer 21, the high-voltage capacitor 22, and the magnetron 23 are located in different chambers (the waveguide box 24 plays a role of physical isolation), reducing the safety risk that the rotating stirring blade 32 affects the important components of the microwave generating assembly 23, and further improving the safety of the microwave oven.

[0066] Specifically, the working principle of the microwave generating assembly 2 and the microwave stirring assembly 3 is as follows: After being powered on, the high-voltage transformer 21 and the high-voltage capacitor 22 (including the high-voltage diode) work to generate high voltage to make the magnetron 23 work to generate microwaves, and the microwaves are introduced into the waveguide cavity 25 through the waveguide box 24; at the same time, the motor 31 drives the stirring blade 32 to rotate, and the rotating stirring blade 32 scatters the microwaves inside the waveguide cavity 25, so that the microwaves are evenly distributed in the cooking cavity 10, thereby making the food in the cavity 1 heated evenly.

[0067] Furthermore, it further includes a heat dissipation assembly 4, and the heat dissipation assembly 4 is arranged above the microwave generating assembly 2 and the microwave stirring assembly 3;

[0068] The air outlet surface of the heat dissipation assembly 4 faces downward and is arranged directly opposite to the magnetron 23;

[0069] The magnetron 23 is arranged close to the rear side of the flat microwave oven, and there is a gap between the projections of the magnetron 23 and the high-voltage transformer 21 in the vertical direction.

[0070] Since the microwave generating assembly (including the high-voltage transformer 21, the high-voltage capacitor 22, the magnetron 23, etc.) and the microwave stirring assembly (including the motor 31 and the stirring blade 32) generate a large amount of heat during operation, arranging the heat dissipation assembly 4 above the microwave generating assembly 2 and the microwave stirring assembly 3 can directly dissipate heat from these two key assemblies, avoiding problems such as component aging and deformation caused by high temperature, reducing performance fluctuations or failures caused by overheating, thereby improving the overall stability of the device and extending the service life of the microwave oven.

[0071] In a specific preferred embodiment, the motor 31 and the magnetron 23 are located on the same side of the waveguide box 24, and the motor 31 and the magnetron 23 are horizontally distributed. The magnetron 23 is disposed near the rear side of the flat microwave oven. The projections of the motor 31 and the magnetron 23 overlap in the horizontal direction. The projections of the motor 31 and the high-voltage transformer 21 overlap in the vertical direction. The projections of the magnetron 23 and the high-voltage transformer 21 do not overlap in the vertical direction, and there is a gap between the projections of the magnetron 23 and the high-voltage transformer 21 in the vertical direction. The projections of the magnetron 23 and the high-voltage transformer 21 partially overlap in the horizontal direction, and the air outlet surface of the heat dissipation component 4 faces downward and is directly opposite to the magnetron 23. In the present utility model, the heat dissipation component, whose air outlet surface is generally vertically arranged, is adjusted to be horizontally arranged, reducing the blockage of the heat dissipation holes on the rear plate. By adopting the above-mentioned compact staggered distribution, the components in the flat microwave oven can be distributed on the same outer side, while achieving a good heat dissipation effect. Compared with flat microwave ovens of the same size, the accommodation space of the cooking cavity 10 can be maximized.

[0072] Furthermore, the internal height of the cooking cavity 10 is M, and the overall height of the flat microwave oven is N, where the range of M:N is 0.6 - 0.8.

[0073] By designing that the internal height of the cooking cavity accounts for 3 / 5 - 4 / 5 of the overall height of the flat microwave oven. Specifically, the height of the cooking cavity is greater than 200 mm, preferably 260 mm, which can ensure that the cooking cavity has enough space to accommodate and heat food, without causing waste of the height of the furnace body. This design enables the space in the cooking cavity to be more reasonably utilized, improving the cooking efficiency of the microwave oven. Due to the increase in the internal height of the cooking cavity, more or larger food containers can be placed, providing more cooking options for users. At the same time, because the space in the cooking cavity is larger, the reflection and penetration of microwaves can better play a role, forming a more uniform "rotating wave" magnetic field, thereby heating the food more evenly and efficiently, improving the cooking effect of the food.

[0074] Furthermore, the bottom plate of the cooking cavity 10 is made of stainless steel. The middle part of the bottom plate 14 is recessed downward to form a sunken part 141, and the four side surfaces 142 of the sunken part 141 are bent downward obliquely from the horizontal plane 143.

[0075] The housing is a cavity with an open front formed by side plates, a rear plate, a top plate and a bottom plate on both sides. Since the microwave generating assembly 2 and the microwave stirring assembly 3 are arranged on the sides in the present utility model, the isolation plate and the turntable structure at the bottom can be cancelled, and no other structure is arranged at the bottom of the oven cavity assembly 1, so that the internal accommodation space of the cooking cavity 10 can extend downward, expanding the accommodation space. Since there is no isolation plate made of materials such as microcrystalline glass or borosilicate glass that can penetrate microwaves, the production cost is also saved. The bottom plate of the cooking cavity 10 is made of stainless steel bottom plate 14. Stainless steel has excellent durability and corrosion resistance, and can resist the erosion of various oils, food residues and cleaning agents that may be generated during cooking, so as to keep the cooking cavity of the microwave oven clean and hygienic. Further, a sunken part 141 formed by the middle part of the bottom plate 14 sinking downward further increases the accommodation space of the cooking cavity 10.

[0076] Further explanation, the housing 6 surrounds the oven cavity assembly 1, the microwave generating assembly 2, the microwave stirring assembly 3 and the heat dissipation assembly 4. The housing 6 provides additional protection for the various components of the microwave oven, preventing the direct influence of external factors on the internal components, such as dust, moisture, foreign objects, etc., thereby improving the safety and durability of the microwave oven. At the same time, the housing 6 can play a role in sound insulation or noise reduction, reducing the noise generated by the microwave oven during operation and providing a more comfortable use environment for users.

[0077] Furthermore, the rear plate of the housing 6 is provided with heat dissipation holes 61, and the magnetron 23 and the heat dissipation assembly 4 are arranged at positions facing the heat dissipation holes 61.

[0078] The microwave generating assembly 2 is arranged on the side of the oven cavity assembly 1. The housing 6 surrounds and protects the oven cavity assembly 1 and other internal structures. The rear plate of the housing 6 is provided with heat dissipation holes 61, and the magnetron 23 and the heat dissipation assembly 4 are arranged at positions facing the heat dissipation holes 61, which facilitates the heat dissipation assembly 4 to fan-cool the magnetron 23 and perform heat exchange with the outside through the heat dissipation holes 61. The technical principle of the present utility model is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be interpreted in any way as a limitation on the protection scope of the present utility model. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and these embodiments will fall within the protection scope of the present utility model.
