[0021] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] As attached Figure 1-6 The heat-insulating door panel for a rice cooker shown in the figure comprises an inner door panel 1, an outer door panel 2, a heat-insulating assembly 3 and a door handle 4. The heat-insulating assembly 3 comprises a heat-insulating board 5, a cotton pressing board 6 and heat-insulating cotton 7. The inner door panel 1 is a rectangular plate-shaped structure and a mica board 8 is fixedly installed on one side close to the outer door panel 2. The shape and size of the mica board 8 are consistent with the shape and size of the inner door panel 1. The cotton pressing board 6 and the heat-insulating board 5 are both cubic box-shaped structures with one side being open. The box bottom of the cotton pressing board 6 is fixedly connected to the mica board 8. In this embodiment, bolts are used to penetrate the inner door panel 1, the mica board 8 and the cotton pressing board 6 in sequence and are fixedly connected with nuts. The box opening direction of the cotton pressing board 6 is close to the insulation board 5, and the box opening direction of the insulation board 5 is close to the cotton pressing board 6. The box bottom area of the insulation board 5 is larger than the box bottom area of the cotton pressing board 6, so that the insulation board 5 can be put outside the cotton pressing board 6 and a filling space is formed between the two. The bottom of the insulation board 5 and the bottom of the cotton pressing board 6 fit each other, and the insulation cotton 7 is filled into the entire filling space. The outer door panel 2 is also a rectangular structure. The four sides of the outer door panel 2 are bent toward the inner door panel 1 to form the door panel side edge 9. The upper part, left part and right part of the door panel side edge 9 are bent toward the center direction of the outer door panel 2 to form the door panel inner edge 10. A plurality of strip-shaped heat dissipation holes 11 are evenly arranged on the door panel side edge 9. The outer door panel 2 is fixedly mounted on the mica board 8 through the door panel inner edge 10 and covered with the heat insulation component 3. In this embodiment, bolts are also used to penetrate the inner door panel 1, the mica board 8 and the door panel inner edge 10 in turn and are fixedly connected with nuts. The door panel inner edge 10 and the inner door panel 1 are connected by a The mica board 8 is used as a spacer, and the mica board 8 has good heat insulation performance. Heat is not easily transferred from the inner door panel 1 to the outer door panel 2. Similarly, heat is not easily transferred to the cotton pressing board 6. The lower edge of the inner door panel 1 is bent toward the direction of the outer door panel 2 to form an inner panel lower edge 12. The inner panel lower edge 12 is fixedly connected to the lower part of the door panel side edge 9 by bolts and nuts. The inner panel lower edge 12 can also support the mica board 8, and increase the connection direction between the outer door panel 2 and the inner door panel 1 from a single inside-outside direction to two mutually perpendicular directions inside-outside and up-down, thereby making the connection between the outer door panel 2 and the inner door panel 1 tighter.
[0023] An air insulation layer 13 is provided between the insulation board 5 and the outer door panel 2. The air insulation layer 13 is connected to the outside through the heat dissipation holes 11. Four isolation brackets 14 are provided in the air insulation layer 13. One end of the isolation bracket 14 is fixedly connected to the insulation board 5, and the other end of the isolation bracket 14 is in contact with the outer door panel 2. The air insulation layer 13 separates the insulation board 5 and the outer door panel 2 so that the two do not directly contact each other, further improving the heat insulation effect of the door panel. In addition, the design of the heat dissipation holes 11 has the effect of delaying metal heat transfer and heat dissipation, thereby increasing the safety of the door panel. The door handle 4 includes a handle body 15 and an installation reinforcement plate 16, the installation reinforcement plate 16 includes a bottom plate 17, both ends of the bottom plate 17 extend to the same side and are bent twice to form a step-shaped floating plate 18, the installation reinforcement plate 16 is arranged in the air insulation layer 13, and the bottom plate 17 of the installation reinforcement plate 16 is fixedly installed on the insulation plate 5, and the floating plate 18 extends to the outer door panel 2. The handle body 15 is a U-shaped structure and both ends are attached to the outer door panel 2. Bolts penetrate the handle body 15, the outer door panel 2 and the floating plate 18 in turn and cooperate with nuts to fix the three at the same time. The two floating plates 18 correspond to the two ends of the handle body 15 respectively.
[0024] like Figure 7 As shown, the heat-insulating door panel and the rice cooker 19 provided in this embodiment are used in combination, the inner door panel 1 is leaning against the inside of the rice cooker 19, the outer door panel 2 is leaning against the outside of the rice cooker 19, and an insulation component 3 including a mica board 8, a cotton pressing board 6, insulation cotton 7 and an insulation board 5 is arranged between the outer door panel 2 and the inner door panel 1. The multi-layer design of the mica board 8, the cotton pressing board 6, the insulation cotton 7 and the insulation board 5 greatly improves the insulation effect of the door panel; in addition, the design that the door handle 4 is fixedly connected to the insulation component 3 and the outer door panel 2 at the same time also improves the tensile strength that the door handle 4 can withstand.
