[0048] See also Figures 1 to 3The present invention provides a base plate assembly 100 for a cooking appliance 500. The base plate assembly 100 includes a plastic base plate 80 and an electrical component 50. The plastic base plate 80 is provided with a receiving groove 10; the lower portion of the electrical component 50 is received in the receiving groove 10, and the upper portion protrudes out of the receiving groove 10.

[0049] In the above-mentioned base plate assembly 100, the base plate assembly 100 includes a plastic base plate 80. The plastic base plate 80 can be manufactured through an integrated molding process, so that structural parts including the accommodating groove 10 can be integrated on the plastic base plate 80 to realize an integrated design of the plastic base plate 80, thereby reducing the use of parts to a certain extent and improving the reliability and assembly efficiency of the cooking appliance 500.

[0050] Specifically, cooking appliances 500 refer to various appliances for cooking and preparing food, including but not limited to microwave ovens, microwave ovens, microwave ovens, integrated stoves, ovens, etc. Figure 6 Cooking appliance 500 may be a microwave oven, comprising a power supply, a cooking cavity 300, and an electrical chamber 200. The electrical components may include an inverter assembly. During operation, the inverter assembly in the electrical chamber 200 controls the output power by varying the power frequency, supplying it to the magnetron in the electrical chamber 200. The magnetron continuously generates microwaves, which are then transmitted through the waveguide and stirring antenna in the electrical chamber 200 to the cooking cavity within the cooking cavity 300, heating the food therein.

[0051] The bottom plate assembly 100 is located at the bottom of the cooking cavity 300 and the electrical chamber 200. The bottom plate assembly 100 includes a plastic bottom plate 80. The plastic bottom plate 80 is easy to process and form, and can provide physical support for the electrical component 50 and the cooking appliance 500, ensuring that the electrical component 50 is stably fixed inside the cooking appliance 500, and to a certain extent, preventing movement or damage during transportation or use. As an insulating material, it can prevent the electrical component 50 from coming into direct contact with the external environment, thereby avoiding the risk of electric shock. It also has a thermal insulation effect, to a certain extent preventing the heat generated during the cooking process from being directly transferred to the outer casing of the cooking appliance 500, protecting user safety and reducing external temperature increases. The plastic bottom plate 80 is manufactured using an integrated molding process, which can more efficiently utilize materials, reduce production costs and time, and to a certain extent reduce the number of parts and steps in the assembly and disassembly process. It also ensures the sealing and overall stability of the interior of the cooking appliance 500.

[0052] In summary, the plastic base plate 80 can not only optimize the production process to a certain extent, but also has good performance, which can ensure the safe and stable operation of the cooking appliance 500.

[0053] In some embodiments, the plastic bottom plate 80 includes an integrally formed support plate 12 and a side plate 14 . The side plate 14 is protruded from the top of the support plate 12 . The side plate 14 and the support plate 12 together form a receiving groove 10 .

[0054] In this way, stronger structural support can be provided for the electrical component 50, which facilitates the installation and disassembly of the electrical component 50 and makes it easier to achieve good sealing. This design also saves materials and can reduce production costs to a certain extent.

[0055] Specifically, please combine Figure 7 and Figure 8 In the related art, the base assembly 150 consists of a base plate 54, electrical components, an electrical component base 52, and a bracket. The electrical component base 52 is fixed to the base plate 54, and the bracket is fixed to the electrical component base 52. The electrical component base 52 and the bracket are connected using screws, clips, and other means to ensure the electrical components are stably installed within the cooking appliance 500. This results in independent structural components, resulting in an excessive number of parts, increasing the overall cost, and reducing structural reliability. The three modules are installed independently, resulting in an excessive number of installation modules, which affects assembly efficiency and increases the difficulty of manufacturability and maintainability.

[0056] In the present invention, the plastic bottom plate 80 is formed by an integral molding process with the side plates 14 and the support plate 12 to form a receiving groove 10 to replace the electrical component base 52 in the related art to accommodate and fix the electrical component 20.

[0057] The function of the receiving groove 10 is to install and fix the electrical component 50. Figure 3 In an embodiment of the present invention, the side panels 14 and the support panels 12 together form a receiving groove 10. Compared with the method of forming the receiving groove 10 by recessing inward, the method of forming the receiving groove 10 by the side panels 14 and the support panels 12 together makes the installation and removal of the electrical component 50 more convenient. The side panels 14 add additional support points to a certain extent, and the enclosed receiving groove 10 can provide stronger structural support, thereby improving the rigidity and durability of the cooking appliance 500. The receiving groove 10 enclosed by the side panels 14 can also more easily achieve good sealing, preventing dust, liquid and other contaminants from entering the interior of the electrical component 50. The design of the side panels 14 and the support panels 12 together enclosing the receiving groove 10 also saves materials and can reduce production costs to a certain extent.

[0058] In some embodiments, the base plate assembly 100 further includes a support foot 16 integrally formed with the support plate 12 , and the support foot 16 is disposed at the bottom of the support plate 12 .

[0059] The integrated design of the plastic base 80 and the support legs 16 reduces the number of steps required to install the support legs 16, eliminates potential weaknesses associated with conventional connection methods, and improves overall structural strength and stability. The support legs 16 are made of a plastic material with a certain degree of anti-slip properties, preventing the cooking appliance 500 from sliding on the kitchen countertop while also protecting the countertop from heat damage.

[0060] Specifically, please combine Figure 7 and Figure 8 In the related art, the base plate 54 of the base plate assembly 150 is made of sheet metal. The furnace feet 56 are typically secured to the metal base plate 54 using screws, glue, or snap fasteners to support the weight of the entire unit. The furnace feet 56 are typically made of rubber or plastic for anti-slip properties. This results in independent structural components, resulting in an excessive number of parts, increasing overall unit cost and reducing structural reliability. Each module is installed independently, resulting in an excessive number of modules, affecting assembly efficiency and increasing the difficulty of manufacturability and maintainability.

[0061] In the embodiment of the present invention, the plastic base plate 80 and the support legs 16 are integrally formed, and the support legs 16 are formed by providing a plurality of raised features on the bottom of the plastic base plate 80, replacing the stove legs 56 of the metal base plate 54 in the related art. In this way, the steps of assembling the stove legs 56 can be reduced, which reduces the production cost and time to a certain extent, and eliminates the weaknesses that may exist in traditional connection methods (such as screw holes or welding points), thereby improving the overall structural strength and stability of the cooking appliance 500. The present invention does not specifically limit the number of support legs 16. Figure 2 In the embodiment, the number of the supporting legs 16 is four.

[0062] The shape design of the support legs 16 generally takes into account stability and durability, ensuring that the cooking appliance 500 is placed stably, preventing the cooking appliance 500 from sliding, and protecting the placement table. Figure 2 In the embodiment, the shape of the support leg 16 is substantially cylindrical. In other embodiments, the shape of the support leg 16 can be conical or T-shaped.

[0063] In some embodiments, the electrical component 50 includes a bracket 18 and an electrical component 20. A clip 22 is provided on one of the bracket 18 and the side panel 14, and a buckle 24 is provided on the other. The bracket 18 is connected to the side panel 14, and the clip 22 is locked in the buckle hole 24 to fix the connection between the bracket 18 and the side panel 14. The electrical component 20 is located in the accommodating space 26 surrounded by the bracket 18 and the side panel 14.

[0064] In this way, on the one hand, the side panel 14 and the bracket 18 are connected by the buckle 22 and the buckle hole 24, which facilitates the installation and disassembly of the electrical component 50; on the other hand, the accommodating space 26 can protect the electrical component 20 to prevent the electrical component 20 from being damaged.

[0065] In the embodiment of the present invention, the side panel 14 and the bracket 18 are connected by means of a buckle 22 and a buckle hole 24. The buckle 22 is provided on the outer surface of the side panel 14, and the buckle hole 24 is provided on the bracket 18. In other embodiments, the buckle 22 may be provided on the outer surface of the bracket 18, and the buckle hole 24 may be provided on the side panel 14. The position and distance between the buckle 22 and the buckle hole 24 may be specifically defined according to actual needs and are not specifically limited in the present invention.

[0066] The present invention does not specifically limit the number of buckles 22 and buckle holes 24. Figure 3 In the embodiment, there are four buckles 22 and four button holes 24 , and one buckle 22 is passed through one corresponding button hole 24 .

[0067] Specifically, the buckle 22 and the buckle hole 24 are mainly used to limit the relative position between the bracket 18 and the side plate 14 by clamping the buckle 22 in the buckle hole 24. Figure 3 The installation and connection process for the electrical assembly 50 begins by placing the electrical component 20 in the receiving groove 10. The bracket 18 then moves downward, allowing the inner surface of the bracket 18 to contact the outer surface of the side panel 14. This in turn causes the buckle hole 24 to move downward, allowing the buckle 22 to engage with the buckle hole 24, thereby restricting the bracket 18 from moving forward, backward, left, right, or up and down. In this way, the side panel 14 and the bracket 18 define a receiving space 26 to accommodate the electrical component 20. It will be appreciated that the receiving groove 10 may constitute a portion of the receiving space 26.

[0068] Optionally, the bracket 18 and the side panel 14 are detachably connected to facilitate maintenance of the electrical components 20. Optionally, the electrical components 20 are fixed to the support plate 12 by means including but not limited to bolts and snaps. Optionally, the bracket 18 can also be integrally formed with the plastic base plate 80, which can further reduce the number of parts.

[0069] exist Figure 3 In the process of disassembling the electrical component 50, first press the buckle 22 so that the buckle 22 disengages from the buckle hole 24 into the accommodating space 26, then drive the bracket 18 to move from bottom to top to disengage from the side panel 14, so that the bracket 18 is taken out from bottom to top, and finally the electrical component 20 is taken out from between the side panels 14.

[0070] Thus, the disassembly of the electrical component 50 can be facilitated.

[0071] Please combine Figure 3, the shapes of the buckle 22 and the buttonhole 24 are roughly rectangular. In other embodiments, the shapes of the buckle 22 and the buttonhole 24 can also be other regular or irregular shapes.

[0072] In some embodiments, the bracket 18 is provided with a first opening 28 and a second opening 30 on both sides along the first direction, respectively. The first opening 28 and the second opening 30 are connected to the accommodating space 26 .

[0073] In this way, the first opening 28 and the second opening 30 are connected to form a heat dissipation channel to dissipate heat from the electrical component 20 , thereby increasing the air flow path and improving the heat dissipation efficiency to a certain extent.

[0074] Specifically, please combine Figure 3 and Figure 6 The first direction is the front-to-back direction. In an embodiment of the present invention, the electrical component 20 may include an inverter. During operation of the cooking appliance 500, the inverter converts low-frequency direct current into high-frequency alternating current and transmits it to the magnetron, causing the magnetron to continuously generate microwaves. These microwaves are transmitted to the cooking cavity 300 through the waveguide and the stirring antenna, heating the food within the cooking cavity. During operation, the inverter generates a large amount of heat. If this heat cannot be dissipated promptly, it may damage the electronic components within the inverter, affecting operating efficiency and performance, and even shortening its service life. The bracket 18 is connected to the side panel 14 via a buckle 22 and a buckle hole 24 to form a housing space 26. A first opening 28 and a second opening 30 are respectively provided on either side of the bracket 18 along the first direction. The first opening 28 and the second opening 30 communicate with the housing space 26. This creates a heat dissipation channel to dissipate heat from the electrical component 20. By increasing the airflow path, heat dissipation efficiency is improved to a certain extent, extending the service life of the electrical component 20 and reducing failures and maintenance costs caused by overheating. The sizes of the first opening 28 and the second opening 30 can be specifically limited according to actual needs, and the present invention does not impose any specific limitations.

[0075] In some embodiments, the bracket 18 is provided with a guide plate 32 on one side of the first opening 28. The guide plate 32 extends obliquely along the top edge of the first opening 28 toward the outside of the electrical component 20. In the embodiment of the present invention, the first opening 28 is an air outlet, and the second opening 30 is an air inlet.

[0076] In this way, the guide plate 32 can guide the air flow and increase the air output, while more evenly transferring the heat from the electrical component 20 to the bracket 18, further improving the heat dissipation efficiency.

[0077] Specifically, the internal structure of the cooking appliance 500 is very compact and the space is very limited. How to effectively improve the heat dissipation efficiency without significantly increasing the overall size of the electrical components 50 is a problem that needs to be solved. Figure 1 and Figure 3 The guide plate 32 extends obliquely along the top edge of the first opening 28 toward the outside of the electrical component 20. This structural design not only provides additional mechanical support for the electrical component 20, but also guides air flow to form a convection heat dissipation channel, thereby improving heat dissipation efficiency. The size of the guide plate 32 can be specifically limited according to actual needs, and this utility model does not impose specific restrictions on this. Figure 1 In the embodiment, the guide plate 32 extends obliquely along the top edge of the first opening 28 toward the upper rear of the electrical component 20 .

[0078] Please combine Figure 1 Optionally, the guide plate 32 is in the shape of a rectangular plate, which is simple and easy to manufacture and can provide a larger heat dissipation area. In other embodiments, the guide plate 32 can also be in other regular or irregular shapes.

[0079] In some embodiments, the electrical component 20 includes a circuit board 34, the circuit board 34 is provided with a positioning hole 36, the plastic base plate 80 includes a positioning rib 38 integrally formed with the support plate 12, the positioning rib 38 is located in the receiving groove 10, and the positioning rib 38 is cooperated with the positioning hole 36 to position the circuit board 34 in the receiving groove 10.

[0080] In this way, the circuit board 34 and the support plate 12 are connected through the positioning holes 36 and the positioning ribs 38 , which facilitates the fixation and installation of the electrical component 20 .

[0081] The present invention does not impose any specific restrictions on the number of positioning holes 36 and positioning ribs 38. Figure 3 In the embodiment, the number of the positioning holes 36 and the number of the positioning ribs 38 are both two, and one positioning hole 36 is provided corresponding to one positioning rib 38 .

[0082] Specifically, the mutual cooperation between the positioning hole 36 and the positioning rib 38 can position the electrical component 20 in the receiving groove 10, thereby facilitating the fixing of the electrical component 20. Figure 4 To install the circuit board 34, first move the circuit board 34 from top to bottom. The positioning holes 36 on the circuit board 34 align with the positioning ribs 38 in the receiving slot 10. The positioning holes 36 are then aligned with the positioning ribs 38. The positioning ribs 38 penetrate the positioning holes 36 to control the position of the circuit board 34 in the receiving slot 10. This ensures the position of the electrical component 20. The electrical component 20 can then be secured using fasteners such as screws.

[0083] In this way, the stability of the installation of the electrical component 20 can be further improved.

[0084] Please combine Figure 4 Optionally, the positioning hole 36 is in the shape of an elongated strip, and the positioning rib 38 is in the shape of a flat plate. In other embodiments, the positioning hole 36 is in the shape of a circle, and the positioning rib 38 is in the shape of a cylinder.

[0085] In some embodiments, the plastic base plate 80 is provided with a through hole 44 along the thickness direction, and the through hole 44 is spaced apart from the receiving groove 10 .

[0086] In this way, the through hole 44 can save the material of the plastic bottom plate 80 , thereby reducing the cost of the cooking appliance 500 .

[0087] Specifically, please combine Figure 5 The plastic base 80 includes a support plate 12, which is provided with through holes 44 along its thickness. The thickness of the support plate 12 is defined as the vertical direction. The formation of through holes 44 along the thickness of the plastic base 80 reduces the material used in the plastic base 80, thereby reducing the cost of the cooking appliance 500. The size and number of through holes 44 can be determined based on practical needs and are not specifically limited in this invention.

[0088] Optionally, in Figure 5 In the embodiment, the shape of the through hole 44 is a rounded rectangle. In other embodiments, the shape of the through hole 44 can be rectangular or circular. Figure 5 In the figure, the position corresponding to the through hole 44 upward is the cooking cavity 300.

[0089] In some embodiments, the plastic base plate 80 includes an integrally formed support plate 12, a first enclosure 40 and a reinforcing rib 42, a through hole 44 passes through the support plate 12, the first enclosure 40 is protruded from the top of the support plate 12 and connected to the edge of the through hole 44, and the reinforcing rib 42 connects the top of the support plate 12 and the side of the first enclosure 40 facing away from the through hole 44.

[0090] In this way, the first enclosing plate 40 and the reinforcing ribs 42 can increase the structural strength of the support plate 12 , thereby increasing the stability of supporting the cooking cavity 300 .

[0091] Specifically, please combine Figure 5 The first enclosing panel 40 can extend along the edge of the through-hole 44 toward the center of the through-hole 44, ensuring the structural strength of the support plate 12 at the edge of the through-hole 44 and preventing or reducing deformation of the support plate 12. The design of the first enclosing panel 40 can also isolate the cooking cavity 300 from other components, preventing internal collisions. The size of the first enclosing panel 40 can be specifically determined based on actual needs and is not specifically limited by this invention.
