[0003] In the related art, an oven is usually used to dry the electrode. The existing oven includes a box body and a door, and a door frame is provided between the box body and the door. When the oven is drying, the interior of the oven is a high-temperature environment. The contact between the door frame and the high-temperature environment easily leads to a high temperature of the door frame, and the heat is transferred to the outside of the oven through the door frame. In order to reduce the heat loss inside the oven, an insulation layer is usually provided between the door frame and the box body to isolate the door frame from direct contact with the box body.
[0004] However, it is still difficult to isolate the connection between the door frame and the box body. When heat radiation reaches the connection of the door frame, the door frame is prone to temperature rise and part of the temperature is transferred to the outside of the door frame.

[0028] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.
[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.
[0030] Embodiment 1:
[0031] The utility model provides an insulating door frame which can be used in heating equipment such as an oven, and is beneficial to improving the thermal bridge blocking efficiency to achieve a good thermal insulation effect.
[0032] Reference Figure 1 The utility model provides an insulating door frame, including a frame 1. Specifically, the frame 1 is a rectangular frame 1. It can be understood that the shape of the frame 1 is not specifically limited here, and technicians in the relevant field can replace or improve it on this basis. In some specific embodiments shown, a rivet hole 6 is opened through the frame 1, and the frame 1 can be assembled with rivets at the rivet hole 6 to be fixedly installed on the frame of the oven.
[0033] A plurality of first heat-insulating grooves 2 are provided through the frame 1, and the plurality of first heat-insulating grooves 2 are arranged at intervals along the edge of the frame 1. Further, the spacing between two adjacent first heat-insulating grooves 2 is 10 to 30 mm. In some specific embodiments shown, the spacing between two adjacent first heat-insulating grooves 2 is 10 mm. The spacing between two adjacent first heat-insulating grooves 2 is appropriate, which can reduce the area of the thermal bridge while ensuring the structural strength of the frame 1. The first heat-insulating grooves 2 form a partition on the frame 1, and the first heat-insulating grooves 2 can serve as a first barrier to block the heat radiation reaching the frame 1.
[0034] A plurality of second heat-insulating grooves 3 are provided through the frame 1. The plurality of second heat-insulating grooves 3 are arranged at intervals along the edge of the frame 1 and are located on the side of the first heat-insulating groove 2 away from the heat source, forming a heat barrier on the frame 1. The second heat-insulating grooves 3 are arranged alternately with the first heat-insulating grooves 2. When the heat radiation reaches the frame 1, there is heat transfer between the two adjacent first heat-insulating grooves 2, and the heat is transferred to the second heat-insulating grooves 3. The second heat-insulating grooves 3 can not only block part of the heat, but also extend the heat transfer path, which is beneficial to improve the efficiency of heat blocking. In a preferred embodiment, the spacing between the second heat-insulating grooves 3 and the first heat-insulating grooves 2 along the thickness direction of the frame 1 is 5 to 30 mm. In some specific embodiments shown, the spacing between the second heat-insulating grooves 3 and the first heat-insulating grooves 2 along the thickness direction of the frame 1 is 5 mm.
[0035] Furthermore, the distance between two adjacent second thermal insulation grooves 3 is 10-30 mm. For example, in some specific embodiments shown, the distance between two adjacent second thermal insulation grooves 3 is 10 mm.
[0036] The frame 1 is provided with a third heat insulation groove 4 at the corner. Furthermore, a plurality of third heat insulation grooves 4 are provided, and the plurality of third heat insulation grooves 4 are spaced apart along the thickness direction of the frame 1. As shown in some specific embodiments, two third heat insulation grooves 4 are provided. It can be understood that this is not a specific limitation on the number of third heat insulation grooves 4. Technicians in the relevant field can select the number of third heat insulation grooves 4 according to the strength of the frame 1. Among them, the spacing between the third heat insulation groove 4 and the first heat insulation groove 2 is 10 to 30 mm. As shown in some specific embodiments, the spacing between the third heat insulation groove 4 and the first heat insulation groove 2 is 10 mm.
[0037] Reference Figure 2When the heat inside the oven reaches the frame 1, the first insulation groove 2 can block part of the heat to form a first barrier, while part of the heat is transferred to the second insulation groove 3 through the two adjacent first insulation grooves 2. The second insulation groove 3 can continue to block the heat from being transferred to the outside of the oven through the frame 1 and can extend the heat transfer path. When the heat radiation reaches the corner of the frame 1, the third insulation groove 4 can block the heat from being transferred from the corner of the frame 1 to the outside of the oven. The arrangement of the first insulation groove 2, the second insulation groove 3 and the third insulation groove 4 can form three obstacles on the frame 1 to block the heat while extending the heat transfer path, thereby improving the insulation effect of the frame 1.
[0038] Example 2
[0039] In order to further improve the heat insulation effect of the frame 1, the difference between this embodiment and the above embodiment is that Figure 1 The spacing between two adjacent first thermal insulation grooves 2 is 30 mm. At this time, the gap between the first thermal insulation grooves 2 is suitable to reduce the thermal bridge area and ensure the structural strength of the frame 1.
[0040] Furthermore, the cross-section of the first insulation groove 2 is rectangular. In some specific embodiments shown, the cross-section of the first insulation groove 2 is preferably rectangular. The first insulation groove 2 can more effectively block the flow of heat through the right angle, and can significantly reduce the thermal bridge area, thereby improving the insulation effect of the first insulation groove 2. Among them, the length of the first insulation groove 2 is ≤350mm, and the width of the first insulation groove 2 is ≤35mm. In some specific embodiments shown, the length of the first insulation groove 2 is 350mm, and the width of the first insulation groove 2 is 20mm, which is conducive to improving the insulation effect of the first insulation groove 2 on heat transfer.
[0041] The spacing between two adjacent second insulation grooves 3 is 30 mm, and the spacing between the second insulation groove 3 and the first insulation groove 2 along the thickness direction of the frame 1 is 30 mm. At this time, the gap between the second insulation grooves 3 is appropriate, and a longer heat transfer path is formed between the second insulation groove 3 and the first insulation groove 2 to improve the thermal bridge blocking efficiency. Further, the cross-section of the second insulation groove 3 is rectangular. As shown in some specific embodiments, the cross-section of the second insulation groove 3 is preferably rectangular. The right angle of the second insulation groove 3 can improve the problem of faster heat flow at the arc and larger thermal bridge area of the arc, and further improve the thermal insulation effect of the second insulation groove 3. Among them, the length of the first insulation groove 2 is ≤350 mm, and the width of the second insulation groove 3 is ≤35 mm. As shown in some specific embodiments, the length of the second insulation groove 3 is 350 mm, the width of the second insulation groove 3 is 20 mm, and the thermal insulation effect of the second insulation groove 3 is good. The distance between the third heat-insulating groove 4 and the first heat-insulating groove 2 is 30 mm, and a suitable distance is maintained between the third heat-insulating groove 4 and the first heat-insulating groove 2, so that the heat-insulating efficiency of the frame 1 is high.
[0042] Example 3
[0043] The difference between this embodiment and the above embodiment is that Figure 1 , the spacing between two adjacent first insulation grooves 2 is 20 mm. Furthermore, the length of the first insulation groove 2 is 200 mm, and the width of the first insulation groove 2 is 35 mm. The first insulation groove 2 can effectively block the flow of heat and significantly reduce the thermal bridge area, which is beneficial to improving the insulation effect of the first insulation groove 2 on heat transfer.
[0044] The spacing between two adjacent second insulation grooves 3 is 15 mm, and the spacing between the second insulation groove 3 and the first insulation groove 2 along the thickness direction of the frame 1 is 25 mm. At this time, the gap between the second insulation grooves 3 is appropriate, and a longer heat transfer path is formed between the second insulation groove 3 and the first insulation groove 2 to improve the thermal bridge blocking efficiency. Furthermore, the length of the second insulation groove 3 is 250 mm, the width of the second insulation groove 3 is 35 mm, and the thermal insulation effect of the second insulation groove 3 is good. The second insulation groove 3 can not only slow down the flow rate of heat and reduce the thermal bridge area. As shown in some specific embodiments, the spacing between the third insulation groove 4 and the first insulation groove 2 is 20 mm, and the third insulation groove 4 and the first insulation groove 2 maintain a suitable spacing distance, and the thermal insulation efficiency of the frame 1 is high.
[0045] Embodiment 4:
[0046] The difference between this embodiment and the above embodiment is that Figure 1 and Figure 3The frame 1 includes a support section 11 and a connecting section 12. Specifically, the support section 11 is provided with two sections, and the connecting section 12 is provided with two sections. The frame 1 is surrounded by the support section 11 and the connecting section 12, wherein the support section 11 plays a major role in bearing and supporting the frame 1. The first heat insulation groove 2 and the second heat insulation groove 3 are both provided on the support section 11 and the connecting section 12, and the third heat insulation groove 4 is provided at the connection between the support section 11 and the connecting section 12.
[0047] Furthermore, a fourth heat-insulating groove 5 is provided on the connecting section 12. The fourth heat-insulating groove 5 is located on the side of the second heat-insulating groove 3 away from the first heat-insulating groove 2. A plurality of fourth heat-insulating grooves 5 are provided. The plurality of fourth heat-insulating grooves 5 are spaced apart along the length of the connecting section 12. Specifically, the shape of the cross section of the fourth heat-insulating groove 5 is rectangular. The fourth heat-insulating groove 5 forms a fourth barrier for heat transfer on the connecting section 12. The provision of the fourth heat-insulating groove 5 can further reduce the area of the thermal bridge and block the transfer of heat, and ultimately play a role in reducing the conduction of heat from the frame 1. In a preferred embodiment, the fourth heat-insulating groove 5 is staggered with the second heat-insulating groove 3, which can extend the heat transfer path between the fourth heat-insulating groove 5 and the second heat-insulating groove 3. The provision of the fourth heat-insulating groove 5 can further improve the heat-insulating effect of the frame 1 while ensuring the structural strength of the frame 1.
