[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] Example 1
[0035] In existing microwave ovens, moisture seeps into the base plate 1 through the drainage structure at the bottom of the cavity. The moisture then seeps into the tabletop through the vent holes of the base plate 1, causing water to accumulate on the tabletop.
[0036] To address the aforementioned problems, in this embodiment, as follows: Figures 1-4As shown, the applicant proposes a base plate structure for a cooking device 100. The cooking device 100 includes a heating chamber 2, and a drainage structure is provided on the cavity base 21 of the heating chamber 2. The base plate structure includes a base plate 1, which is located below the cavity base 21. A water storage structure is provided on the base plate 1, which is located below the drainage structure. The water storage structure includes a water tank 11, which is used to catch water vapor overflowing from the drainage structure. A reinforcing structure 12 is provided around the water tank 11.
[0037] The base plate structure described in this embodiment has the following features: 1. A water storage structure is located below the drainage structure, allowing water vapor to seep into the base plate 1 through the drainage structure and accumulate in the water storage tank 11, preventing it from overflowing onto the desktop and affecting its cleanliness; 2. A reinforcing structure 12 is provided around the water storage tank 11 to enhance the structural strength and stability of the water storage structure, thereby enhancing the structural strength of the base plate 1; 3. The water storage tank 11 is integrated into the base plate 1, utilizing the principle of gravity drainage, eliminating the need for an additional water pump and reducing the failure rate.
[0038] As a preferred example of this application, such as Figure 4 As shown, the reinforcing structure 12 includes a first reinforcing rib 121 and a second reinforcing rib 122, which are disposed on the left and right sides of the water storage tank 11. A first protrusion is disposed on the front side of the water storage tank 11, and a second protrusion is disposed on the rear side of the water storage tank 11. This arrangement improves the structural strength balance and stability of the water storage tank 11 on the one hand, and increases the height of the water storage tank 11 on the other hand, thereby increasing the capacity of the water storage tank 11.
[0039] As a preferred example of this application, such as Figure 3 As shown, the drainage structure includes a first recess 211 and a second recess 212 disposed on the cavity base 21. Both the first recess 211 and the second recess 212 are annular. The first recess 211 is located on the outer periphery of the second recess 212 and the two are concentrically disposed. A drainage component 213 is disposed on the first recess 211 and / or the second recess 212.
[0040] By optimizing the drainage structure of heating chamber 2, not only can tiered drainage be achieved, but it also makes it easier for users to clean the inside of heating chamber 1.
[0041] The microwave oven produces relatively little condensation during normal use, which collects in the first recess 211, making it easy for users to clean up after use. This prevents condensation from flowing onto the countertop. However, if a container tipps over and a large amount of water flows onto the cavity base 21, some of the water drains from the first recess 211 to the second recess 212 and then flows out through the drainage assembly 213. This effectively prevents condensation from seeping into the motor along the motor shaft, thus avoiding electrical safety hazards. Simultaneously, the first and second recesses 211 and 212 reinforce the cavity base 21, preventing bending or deformation under external forces.
[0042] As a preferred example of this application, such as Figure 2 As shown, the drainage component 213 is a drainage hole 2131, and the connection between the cavity base 21 and the drainage hole 2131 is set as an arc-shaped structure.
[0043] This design has multiple advantages: First, the arc-shaped structure allows water to flow naturally along the curved surface, maintaining a more complete laminar flow state and greatly improving drainage efficiency; Second, the curved surface design of the arc-shaped structure can reduce water flow separation, carrying attached materials out with the water flow and reducing the probability of blockage; Third, it can reduce local stress concentration, improve the structure's impact resistance, and thus extend its service life.
[0044] As a preferred example of this application, such as Figure 2 As shown, an annular rib 2132 is provided on the bottom outer edge of the drain hole 2131, and the annular rib 2132 extends downward and protrudes from the cavity base 21.
[0045] This design prevents water flowing out of the drain hole 2131 from flowing freely along the bottom surface of the cavity base 21, thus preventing it from entering the electrical cavity and causing safety hazards.
[0046] As a preferred example of this application, such as Figure 2 As shown, the first recessed portion 211 and the second recessed portion 212 are respectively formed by the downward recess of the cavity base 21. The bottom surfaces of the first recessed portion 211 and the second recessed portion 212 are at the same height and their projected areas on the horizontal plane are S1 and S2, respectively, where S1 < S2.
[0047] This design allows the first recess 211 to hold less condensate than the second recess 212. The first recess 211 can fully accommodate the small amount of condensate generated during normal use, and the condensate will not enter the second recess 212 or flow out of the microwave oven. However, in the event of an accident such as a container tipping over, some water or other liquids will enter the second recess 212 and be discharged through the drainage assembly 213, effectively preventing motor malfunctions or even safety accidents caused by water seepage.
[0048] As a preferred example of this application, such as Figure 3 As shown, a motor mounting part is provided on the cavity base 21. The motor mounting part is located in the second recess 212. The motor mounting part protrudes upward to form a support platform 214. The support platform 214 and the second recess 212 are concentrically arranged.
[0049] This design allows for a further increase in the height of the motor shaft assembly, providing better waterproofing while also offering installation space for the motor and resulting in a more compact structure.
[0050] As a preferred example of this application, such as Figure 3 As shown, the cavity base 21 is horizontally arranged inside the heating cavity 2. The heating cavity 2 includes a main body 20. The main body 20 also includes a first side plate 22 and a second side plate 23 arranged vertically. The first side plate 22 and the second side plate 23 are located on both sides of the cavity base 21. The first side plate 22 protrudes to the side away from the second side plate 23 to form a third protrusion 221.
[0051] This design can further increase the volume of the heating cavity 2 and reduce microwave leakage at the retrieval port; at the same time, it strengthens the main body 20 to prevent it from bending and deforming.
[0052] As a preferred example of this application, such as Figure 3 As shown, the main body 20 is a one-piece U-shaped structure. This design serves multiple purposes: First, it simplifies the manufacturing process, reduces the number of connection points between components, thereby increasing the overall strength of the main body 20, and consequently improving the overall strength and durability of the cooking equipment 100. Second, the one-piece structure also helps reduce assembly errors, ensuring the precision and stability of the cooking equipment 100. Third, it improves production efficiency, enabling the cooking equipment 100 to be brought to market more quickly. Fourth, this design not only enhances the overall aesthetics of the cooking equipment 100 but also makes it visually more unified and harmonious.
[0053] As a preferred example of this application, a turntable 3 is provided above the cavity base 21. The turntable 3 can shield the drainage assembly 213, making the heating cavity 2 more concise and aesthetically pleasing.
[0054] The base plate structure described in this embodiment has the following features: 1. A water storage structure is located below the drainage structure, allowing water vapor to seep into the base plate 1 through the drainage structure and accumulate in the water storage tank 11, preventing it from overflowing onto the desktop and affecting its cleanliness; 2. A reinforcing structure 12 is provided around the water storage tank 11 to enhance the structural strength and stability of the water storage structure, thereby enhancing the structural strength of the base plate 1; 3. The water storage tank 11 is integrated into the base plate 1, utilizing the principle of gravity drainage, eliminating the need for an additional water pump and reducing the failure rate.

[0058] The advantages of the cooking device described above over the prior art are the same as those of the base plate structure mentioned above, and will not be repeated here.
[0059] While the present invention has been disclosed above, it is not limited thereto.
