Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an anti-heat dissipation device and an oven. Background Art

[0002] The precision oven is a system that heats and bakes the materials in the oven cavity by means of a heating system, temperature sensors, and control systems. In the traditional precision oven, the oven door needs to be opened during the sample loading process, and the opening of the oven door often dissipates a large amount of heat, causing the temperature inside the oven to drop. When the temperature of the precision oven is close to the preset value, it will heat up slowly to ensure the accuracy of the temperature. Therefore, it always takes a long time to reach the preset value after each sample loading, thus affecting the production efficiency of the entire oven.

[0003] In addition, traditional precision drying ovens often have fixed drying space, and for small drying materials, it is not possible to maximize the use of the drying space in the oven.

[0004] Therefore, there is an urgent need for an anti-heat dissipation device and an oven, which can not only reduce the heat dissipation when the oven door is opened, but also flexibly adjust the number of layers of the load support according to the size of the drying material to improve the utilization rate of the oven cavity. Utility Model Content

[0007] A plurality of slots are sequentially arranged on one side of the heat insulation frame from top to bottom, and the object-carrying support members are detachably arranged in the slots accordingly;

[0008] The object-carrying support comprises an object-carrying plate and a partition plate arranged on the object-carrying plate, wherein the partition plate divides the object-carrying support into different drying spaces; each of the heat-insulating sealing blocks corresponds to at least one of the drying spaces.

[0009] As a further improvement of the above solution, the heat-insulating sealing block and the inlet and outlet frame opening are detachably arranged at the corresponding inlet and outlet frame opening through a snap-fit ​​structure or a locking structure.

[0010] As a further improvement of the above solution, the heat insulation frame includes a plurality of longitudinal beams and a plurality of transverse beams, and the longitudinal beams and the transverse beams are crisscrossed and connected to form a plurality of inlet and outlet frame openings corresponding to the drying space.

[0011] As a further improvement of the above solution, the longitudinal beam and the transverse beam are both made of stainless steel.

[0012] As a further improvement of the above solution, the heat insulation frame includes a frame body and longitudinal reinforcement ribs and transverse reinforcement ribs embedded in the frame body;

[0013] The frame body is made of silicate thermal insulation material, which is integrally cast with the longitudinal reinforcement ribs and the transverse reinforcement ribs to form the frame inlet and outlet.

[0014] As a further improvement of the above solution, the material of the carrier plate is stainless steel, and a plurality of through holes are evenly arranged on the carrier plate to allow gas circulation in the oven cavity.

[0015] As a further improvement of the above solution, a pull ring is provided on a side of the thermal insulation sealing block facing away from the object supporting member, for pulling and removing the thermal insulation sealing block.

In addition, in the utility model, a plurality of card slots are also provided on the heat-insulating frame for clamping the load support. Therefore, the height of the load support on the heat-insulating frame can be flexibly adjusted according to the size of the drying material. Especially for small materials, multiple layers of load support can be flexibly arranged, thereby improving the utilization rate of the entire oven cavity and further improving the production efficiency.
