Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0049] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0050] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0051] A microwave oven, as Figure 1 and Figure 2 shown, is applied with a ventilation component, and the structure of the ventilation component is as described below.

[0052] Preferably, the microwave oven comprises a cavity assembly 91, a door assembly 95 and an air frying module 93;

[0053] The air frying module 93 is installed on the top of the cavity assembly 91;

[0054] The cavity assembly 91 includes a cavity front plate 92, and the furnace door assembly 95 and the ventilation assembly are installed on the front side of the cavity assembly 91 through the cavity front plate 92;

[0055] The ventilation assembly is disposed above the oven door assembly 95 and is connected to the space where the air frying module 93 is located through the shutter assembly 8 of the cavity front plate 92 .

[0056] In the present application, the air frying module 93 is arranged on the top of the cavity assembly 91, and the cavity front plate 92 is arranged on the front side of the cavity assembly 91. The oven door assembly 95 and the ventilation assembly located above the oven door assembly 95 are installed with the cavity assembly 91 through the cavity front plate 92. Since the air frying module 93 is higher than the oven door, the space above the cavity front plate 92 is too large. If the oven door is raised to cover the air frying module 93 to match the overall appearance of the microwave oven, the oven door will appear very large and the appearance will be inconsistent. Therefore, the ventilation assembly is arranged above the oven door assembly 95 in the present application to use the ventilation assembly as a decorative part to cover the air frying module 93.

[0057] Furthermore, since the high temperature of the top air frying module 93 affects the temperature rise of the furnace surface, it is necessary to add a heat dissipation channel for the air frying module 93. Therefore, the present application connects the ventilation component to the space where the air frying module 93 is located through the cavity front plate 92, and dissipates the heat generated by the air frying heating tube 94 to the outside through the ventilation component.

[0058] Specifically, Figures 2 to 4 As shown, a ventilation assembly includes a ventilation grille 1 mounted on a cavity front plate 92;

[0059] The ventilation grille 1 comprises a top grille 2, a bottom grille 4 and a plurality of groups of middle grilles 3 installed on a support frame, wherein the plurality of groups of middle grilles 3 are vertically distributed and arranged between the top grille 2 and the bottom grille 4;

[0060] A first ventilation duct 5 is provided between the top grid plate and the adjacent middle grid plate 3;

[0061] A second ventilation channel 6 is provided between the middle grid plates 3 arranged adjacent to each other;

[0062] A third ventilation channel 7 is provided between the bottom grid plate 4 and the adjacent middle grid plate 3;

[0063] The cavity front plate 92 is installed with a shutter assembly 8, and the shutter assembly 8 is provided with a plurality of air induction channels 81;

[0064] The air induction channel 81 is communicated with the first ventilation passage 5 , the second ventilation passage 6 and the third ventilation passage 7 respectively.

[0065] In this embodiment, the ventilation grille 1 is installed on the cavity front plate 92, and the ventilation grille 1 is provided with a support frame for supporting each grid plate, which includes a top grid plate 2, a plurality of vertically arranged middle grid plates 3 and a bottom grid plate 4, and each grid plate complements each other to form a corresponding ventilation duct, specifically including:

[0066] There is a first ventilation channel 5 between the topmost top grid plate and the middle grid plate 3 located below it, there is a third ventilation channel 7 between the bottommost bottom grid plate 4 and the middle grid plate 3 located above it, and there is a third ventilation channel 7 between the middle grid plates 3;

[0067] In order to dissipate the heat in the internal area where the air frying module 93 is located to the outside through the above-mentioned ventilation duct, it is also necessary to set a shutter assembly 8 with an air duct 81 on the cavity front plate 92. The air duct 81 is designed with multiple groups, each corresponding to the respective ventilation duct, to guide the heat to the outside.

[0068] Preferably, the top grid plate 2 comprises a top plate body 21, and an extension edge 22 extending downward is arranged on the outer side of the top plate body 21;

[0069] The middle grid plate 3 comprises a middle plate body 31, and an upper folding edge 32 protruding upward is arranged on the inner side of the middle plate body 31;

[0070] The outer side of the middle plate 31 is provided with a lower folding edge 33 extending downward;

[0071] The bottom grid plate 4 includes a bottom plate body 41 , and a convex edge 42 protruding upward is arranged on the inner side of the bottom plate body 41 .

[0072] Preferably, a gap is left between the upper folded edge 32 of the middle grid plate 3 adjacent to the top grid plate 2 and the top plate body 21 to form a ventilation section 51;

[0073] The upper folded edge 32 of the middle grid plate 3 adjacent to the top grid plate 2 is staggered with the extended edge 22 to form a second ventilation section 52;

[0074] A gap is left between the middle plate body 31 where the middle grid plate 3 adjacent to the top grid plate 2 is located and the extended edge to form a ventilation section 3 53;

[0075] The ventilation section 1 51 , the ventilation section 2 52 and the ventilation section 3 53 are connected in sequence to form the first ventilation passage 5 .

[0076] In this embodiment, the first ventilation duct 5 is jointly constituted by multiple ventilation segments between the top grid plate 2 and the middle grid plate 3. By using the staggered design of the upper folding edge 32 and the top plate body 21, the extension edge 22 and the upper folding edge 32, and the extension edge 22 and the middle plate body 31, the first ventilation duct 5 becomes concealed, enabling the ventilation grid plate to well serve as a decorative piece to block the air frying module 93;

[0077] Furthermore, the staggered design can also prevent external dust from entering the interior of the microwave oven along the first ventilation duct 5, resulting in internal dust accumulation.

[0078] Preferably, for the middle grid plates 3 arranged adjacent to each other in pairs, among which:

[0079] A gap is left between the upper folding edge 32 of the middle grid plate 3 located below and the middle plate body 31 of the middle grid plate 3 located above to form the fourth ventilation segment 61;

[0080] The upper folding edge 32 of the middle grid plate 3 located below is staggeredly arranged with the lower folding edge 33 of the middle grid plate 3 located above to form the fifth ventilation segment 62;

[0081] A gap is left between the middle plate body 31 of the middle grid plate 3 located below and the lower folding edge 33 of the middle grid plate 3 located above to form the sixth ventilation segment 63;

[0082] The fourth ventilation segment 61, the fifth ventilation segment 62, and the sixth ventilation segment 63 are sequentially connected to form the second ventilation duct 6.

[0083] In this application, the cross-section formed by the upper folding edge 32, the middle plate body 31, and the lower folding edge 33 of the middle grid plate 3 is in a shape similar to the letter 'N'. Multiple such 'N'-shaped structures are arranged vertically to improve the concealment of the second ventilation duct 6.

[0084] Preferably, a gap is left between the convex edge 42 and the middle plate body 31 of the middle grid plate 3 adjacent to the bottom grid plate 4 to form the seventh ventilation segment 71;

[0085] The convex edge 42 is staggeredly arranged with the lower folding edge 33 of the middle grid plate 3 adjacent to the bottom grid plate 4 to form the eighth ventilation segment 72;

[0086] A gap is left between the bottom plate body 41 and the lower folding edge 33 of the middle grid plate 3 adjacent to the bottom grid plate 4 to form the ninth ventilation segment 73;

[0087] The seventh ventilation segment 71, the eighth ventilation segment 72, and the ninth ventilation segment 73 are sequentially connected to form the third ventilation duct 7.

[0088] Similarly, the convex edge 42 of the bottom grid plate 4 is located on the inner side, opposite to the extended edge 22 of the top grid plate 2 located on the outer side. Because the lower folded edge 33 of the middle grid plate 3 adjacent to the bottom grid plate 4 can be used as a shield to cover the convex edge 42, the convex edge 42 only needs to be set on the inner side.

[0089] Preferably, the shutter assembly 8 comprises a plurality of vertically distributed and arranged bent plates 82;

[0090] One end of the bending plate 82 is fixed to the cavity front plate 92;

[0091] The plate body of the bending plate 82 bends and extends upward and forms an opening between the other end and the cavity front plate 92 , so that the space between the bending plate 82 and the cavity front plate 92 forms the air induction channel 81 .

[0092] Preferably, a gap 83 is provided between the air induction channel 81 and the cavity front plate 92 to connect the first ventilation channel 5 , the second ventilation channel 6 and the third ventilation channel 7 .

[0093] In this embodiment, the bent plate 82 can be designed to be integrally formed with the cavity front plate 92, and the plate body of the bent plate 82 is bent and extended upward, so that the raised end thereof is bent toward the cavity front plate 92, so that the space between the bent plate 82 and the cavity front plate 92 forms a duct structure as the air induction channel 81, and due to the bending and extension of the bent plate 82, its shape can use the wind flow to introduce the internal heat into the air induction channel 81;

[0094] Furthermore, in order to connect the air induction channel 81 and the first ventilation channel 5, the second ventilation channel 6 and the third ventilation channel 7, a notch 83 is provided on the cavity front plate 92, and heat can flow from the notch 83 to other ventilation channels to achieve circulation.

[0095] 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.
