Therefore, they cannot be understood as limitations on the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Example 1

[0032] See Figure 1 and Figure 2This embodiment provides a visual upper cover assembly, comprising an outer cover 1, a support cover 2, an inner cover 3, and a fan 4. The support cover 2 is mounted within the outer cover 1, and is spaced apart from the top inner wall of the outer cover 1 to form a first mounting space. The inner cover 3 is mounted within the outer cover 1 and positioned below the support cover 2, and is spaced apart from the support cover 2 to form a second mounting space. The fan 4 includes a motor 41 and an auxiliary impeller 42 disposed in the first mounting space, and a working impeller 43 disposed in the second mounting space. The auxiliary impeller 42 and the working impeller 43 are coaxially connected to the motor 41. The outer cover 1 is provided with a perspective portion 11 corresponding to the auxiliary impeller 42.

[0033] The outer cover 1 is a semi-enclosed structure with an opening facing downward. The support cover 2 is installed within the outer cover 1, with the periphery of the support cover 2 corresponding to the middle area of ​​the inner wall of the outer cover 1. The inner cover 3 is installed within the outer cover 1, with the periphery of the inner cover 3 corresponding to the bottom of the inner wall of the outer cover 1. This creates a first installation space between the support cover 2 and the top inner wall of the outer cover 1, and a second installation space between the inner cover 3 and the support cover 2. The connections between the support cover 2 and the outer cover 1, and between the inner cover 3 and the outer cover 1, are both detachable via snap-fit ​​structures.

[0034] Upper cover assemblies are commonly used in kitchen appliances such as rice cookers and air fryers. These appliances often require maintaining uniform temperature within the inner cover 3. The presence of a fan 4 can improve this problem. Fan 4 is installed within the upper cover assembly to drive air flow when activated, thereby exchanging heat with various parts of the inner cover 3 and improving temperature uniformity across the inner cover 3. However, conventional upper cover assemblies enclose the fan 4 within, making its operating status inaccessible. This makes it difficult to promptly detect potential problems with the fan, which in turn affects the temperature uniformity across the inner cover 3.

[0035] To this end, this embodiment distributes the fan 4 between two installation spaces. The working impeller 43 is installed in the second installation space and driven by the motor 41 to rotate and drive the air flow in the second installation space, thereby achieving heat exchange between the air and the inner cover 3 and maintaining a uniform temperature across all parts of the inner cover 3. Furthermore, an auxiliary impeller 42 is provided in the first installation space, coaxially connected to the working impeller 43. A transparent portion 11 is provided on the outer cover 1 corresponding to the auxiliary impeller 42, ensuring synchronous rotation of the auxiliary impeller 42 and the working impeller 43. The operating status of the auxiliary impeller 42 can be observed through the transparent portion 11, thereby indirectly understanding the operating status of the working impeller 43, ensuring the normal operation of the working impeller 43 and enabling timely response if any problems arise with the working impeller 43.

[0036] Specifically, the motor 41 includes a motor body 411 and an output shaft 412. The motor body 411 is installed on the support cover 2. The support cover 2 is provided with a through hole 21 for the output shaft 412 to rotatably pass through and connect to the working impeller 43. The auxiliary impeller 42 is arranged above the motor body 411 and is coaxially connected to the working impeller 43.

[0037] The support cover 2 is used to support and install the motor body 411 to ensure the stability of the installation of the motor body 411. The working impeller 43 is located in the second installation space and is spaced apart from the support cover 2 and the inner cover 3 to ensure smooth rotation of the working impeller 43. The output shaft 412 is vertically arranged to pass through the through hole 21 and connect to the working impeller 43, thereby using the motor body 411 to drive the working impeller 43 to rotate. The working impeller 43 is located in the central area of ​​the second installation space, which not only ensures the stability of the installation of the fan 4, but also can quickly achieve the uniformity of the air in the second installation space. The auxiliary impeller 42 is installed on the motor body 411 and rotates coaxially with the working impeller 43. Once there is a problem with the motor 41 and / or the working impeller 43, it can be observed through the auxiliary impeller 42 through the perspective portion 11 to understand the status of the fan 4 at any time.

[0038] The see-through portion 11 is detachably connected to the outer cover 1. The see-through portion 11 is a transparent structure and can be made of transparent plastic or glass. The detachable connection facilitates replacement when damaged or removal and wiping when contaminated, so as to ensure the integrity and cleanliness of the see-through portion 11 and better observe the auxiliary impeller 42.

[0039] On the basis of the above structure, in order to better achieve the uniformity of the temperature of the inner cover 3, this embodiment has an insulation plate 5 installed in the second installation space. The insulation plate 5 and the support cover 2 and the inner cover 3 are spaced apart to form an upper chamber 6 and a lower chamber 7. The working impeller 43 is installed in the upper chamber 6 and corresponds to the middle part of the insulation plate 5. The middle part and the peripheral edge of the insulation plate 5 are used to connect the upper chamber 6 and the lower chamber 7.

[0040] The insulation board 5 provides insulation, helping to maintain a relatively high temperature within the inner cover 3. A gap exists between the perimeter of the insulation board 5 and the perimeter of the inner cover 3 to ensure that the perimeter edge of the insulation board 5 can communicate with the upper chamber 6 and the lower chamber 7. Thus, when the fan 4 is activated, the impeller 43 rotates, drawing air from the lower chamber 7 into the upper chamber 6 through the center of the insulation board 5. The air then diffuses through the centrifugal structure and is discharged into the lower chamber 7 through the perimeter edge of the insulation board 5. This allows the fan 4 to achieve convection between the upper and lower chambers 6, maintaining a more uniform temperature within the inner cover 3.

[0041] The insulation panel 5 includes a bottom panel 51 and side panels 52. The side panels 52 are located at the peripheral edge of the bottom panel 51 and extend toward the support cover 2 to connect thereto. The bottom panel 51 has an air inlet 511 corresponding to the impeller 43, and the side panels 52 have air outlets 521. A plurality of air outlets 521 are spaced around the bottom panel 51. The air inlet 511 allows the impeller 43 to draw air from the lower chamber 7 into the upper chamber 6. The air outlets 521, due to the centrifugal structure of the impeller 43, allow the drawn air to be evenly diffused in the upper chamber 6 and flow through the air outlets 521 to the lower chamber 7, thereby achieving thermal convection between the air in the upper and lower chambers 6, 7.

[0042] Several air outlets 521 are evenly distributed around the bottom plate 51, and multiple air inlets 511 are evenly spaced corresponding to the working impellers 43. This allows air from the lower chamber 7 to be evenly drawn into the upper chamber 6 through the air inlets 511, then evenly diffused within the upper chamber 6 before evenly flowing into the lower chamber 7 through the air outlets 521, thereby accelerating the uniform distribution of temperature within the inner cover 3.

[0043] Furthermore, a heating element 8 is provided in the upper chamber 6 , and the heating element 8 is arranged close to the heat preservation plate 5 and located on the peripheral side of the working impeller 43 .

[0044] The heating element 8 is a structure such as a heating wire, a light wave heating tube, an electromagnetic heating coil, etc. It is arranged in the upper chamber 6 and can heat the air in the upper chamber 6 and the insulation plate 5, so that the inner cover 3 can be uniformly heated through the circulating heat convection and heat radiation of the air, thereby ensuring a higher temperature of the inner cover 3 while ensuring the uniform temperature of the inner cover 3, thereby preventing the steam in the cooking cavity of household appliances such as electric rice cookers from flowing upward and forming condensation water after encountering the inner cover 3, thereby ensuring the taste of the food.

[0045] For this purpose, the inner cover 3 is detachably connected to the outer cover 1. The bottom plate 51 is provided with a perspective area 512 corresponding to the working impeller 43, and the air inlet 511 is located in the perspective area 512. As the fan 4 is used for a longer time, the synchronization between the auxiliary impeller 42 and the working impeller 43 deteriorates, so that the operating status of the auxiliary impeller 42 observed through the perspective portion 11 may not accurately reflect the operating status of the working impeller 43. In this embodiment, the perspective area 512 is provided on the bottom plate 51 corresponding to the working impeller 43. After the inner cover 3 is removed, the operating status of the working impeller 43 can be observed through the perspective area 512, providing accurate information on the working status of the working impeller 43.

[0046] Furthermore, the inner cover 3 is provided with a transparent portion corresponding to the perspective area 512. In this way, the working state of the working impeller 43 can be observed without removing the inner cover 3, which is convenient for operation.

[0047] Example 2

[0048] See Figure 3This embodiment provides an electric rice cooker, including a rice cooker body 100, an inner pot 200 and the visual upper cover assembly 300 of Example 1. The inner pot 200 is arranged in the rice cooker body 100, and the upper cover assembly 300 is hinged to the rice cooker body 100. The upper cover assembly 300 can be covered on the rice cooker body 100 to form a cooking cavity between the upper cover assembly 300 and the inner pot 200.

[0049] The outer cover 1 of the upper cover assembly 300 is rotatably connected to the pot body 100 via a hinge structure, so that the upper cover assembly 300 can be closed on the pot body 100 or the cooking cavity can be opened.

[0050] When the upper cover assembly 300 of Example 1 is assembled on an electric rice cooker, the temperature uniformity of the inner cover 3 can be achieved by utilizing the coordination of the blower 4, the heat-insulating plate 5, the heating element 8, and the upper and lower chambers 6 and 7. Furthermore, the operating status of the auxiliary impeller 42 can be observed in real time through the perspective portion 11, thereby indirectly understanding the operating status of the working impeller 43 coaxially connected to the auxiliary impeller 42 and achieving visualization of the working impeller 43. In this way, the operating status of the blower 4 can be monitored in real time while the electric rice cooker is in use, allowing for timely response to any problems that arise, thereby ensuring the heat dissipation and / or heating effects of the electric rice cooker.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
