[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides a test chamber, including a box body and a double-door structure. A low-temperature chamber is formed inside the box body, and the double-door structure is arranged at the opening of the box body. The double-door structure can open or close the low-temperature chamber. Through this test chamber, climate environment simulation can be carried out. To ensure the airtightness of the simulation process, a sealing strip is provided on one door body of the double-door mechanism. However, during low-temperature tests, frosting will occur on the sealing strip, which will affect the aesthetics and the experience.

[0041] To solve the above problems, this embodiment also provides a double-door structure, as Figures 1-3As shown in the figure, the double-door structure includes a first door body 10, a second door body 20, a seal 30, and a heating assembly 40. Among them, one side of the first door body 10 in its width direction is pivotally connected to the box body; the second door body 20 is arranged on the other side of the first door body 10, and one side of the second door body 20 away from the first door body 10 is pivotally connected to the box body; the seal 30 is arranged on the side of the first door body 10 close to the second door body 20. When closing the low-temperature chamber, the second door body 20 can press the seal 30 to seal the low-temperature chamber between the first door body 10 and the second door body 20; the heating assembly 40 is arranged between the first door body 10 and the second door body 20 and is connected to the seal 30, and the heating assembly 40 can heat the seal 30.

[0042] In such a double-door structure, the arrangement of the first door body 10 and the second door body 20 facilitates opening or closing of the box body; in addition, a seal 30 is provided on the first door body 10. When the first door body 10 and the second door body 20 are in the closed state, the second door body 20 can press on the seal 30, thereby ensuring that the seal 30 can seal the gap between the first door body 10 and the second door body 20; in addition, the heating assembly 40 can heat the seal 30, and the generated heat can melt the ice and frost on the seal 30, thereby ensuring that no ice and frost remain on the seal 30 after the test, thereby improving the aesthetics and the user experience.

[0043] It should be noted that, in this embodiment, the seal 30 is a sealing strip made of rubber material. Rubber has a low cost and is easy to be made into the required shape. In addition, the double-door structure is arranged on the box body of the test chamber. In other embodiments, it can also be arranged on a refrigerator to prevent the sealing strip of the refrigerator from frosting. The scope of use is not specifically limited in this embodiment.

[0044] To ensure a good defrosting effect, the heating assembly 40 includes heating wires. Heating wires are arranged on both the first door body 10 and the second door body 20. When closing the low-temperature chamber, the heating wires can heat the seal 30. By arranging heating wires on both the first door body 10 and the second door body 20, it can be ensured that when the first door body 10 and the second door body 20 are separated from the seal 30, heating effects can be achieved, thereby generating a good defrosting effect.

[0045] Considering that the heating wires are not easy to fix, as Figure 2 and Figure 3 shown, the heating assembly 40 further includes heat transfer members 41. Heat transfer members 41 are arranged on both the first door body 10 and the second door body 20. The heat transfer members 41 are used to fix the heating wires. When closing the low-temperature chamber, the heat transfer members 41 arranged on the first door body 10 and the second door body 20 can both contact the seal 30, so that the heat of the heating wires can be transferred to the seal 30. By arranging the heat transfer members 41, it is not only convenient to fix the heating wires, but also can quickly transfer the heat to the seal 30 to ensure the defrosting effect.

[0046] It should be noted that the heat transfer member 41 is detachably connected to both the first door body 10 and the second door body 20, which facilitates subsequent maintenance and replacement of parts. In addition, as Figure 3 shown, a receiving space 42 is formed between the heat transfer member 41 and the first door body 10 and the second door body 20. The heating wire can be directly placed in the receiving space 42, ensuring the smooth installation of the heating wire. In addition, as Figure 3 shown, two receiving spaces 42 are formed between the heat transfer member 41 provided on the first door body 10 and the first door body 10. The heating wire provided in one of the receiving spaces 42 can directly contact the seal 30, and the heating wire in the other receiving space 42 can transfer heat to the seal 30 through the heat transfer member 41, ensuring a good heating effect.

[0047] It should be noted here that the heat transfer member 41 is made of stainless steel, which has excellent thermal conductivity and can quickly transfer heat to the seal 30, thus enabling quick defrosting. In other embodiments, metals such as copper and aluminum can also be used to make the heat transfer member 41, as long as it has a high thermal conductivity coefficient, which is not specifically limited in this embodiment. In addition, multiple heating wires are provided on each heat transfer member 41 to ensure sufficient heating temperature can be generated. Even if the frost accumulation is thick, quick defrosting can also be achieved.

[0048] To facilitate the control of the heating temperature, as Figure 1 shown, a control member 60 is provided on the side of the first door body 10 or the second door body 20 facing away from the low-temperature chamber. The control member 60 is communicatively connected to the heating assembly 40, and the control member 60 can control the heating temperature of the heating assembly 40. This setting enables the test personnel to conveniently adjust the heating temperature generated by the heating wire according to the specific temperature of the chamber, ensuring that the frost on the seal 30 can be removed while avoiding resource waste, and has strong practicability.

[0049] In addition, as Figure 2 and Figure 3 shown, a heat insulation member 50 is provided on the side of the first door body 10 close to the second door body 20, and a heat insulation member 50 is provided on the side of the second door body 20 close to the first door body 10. By providing the heat insulation member 50, the gap between the first door body 10 and the second door body 20 can be effectively insulated, ensuring that the low temperature in the chamber will not be transferred to the outside of the first door body 10 and the second door body 20, and thus ensuring that no frost will form on the outside. In addition, the heating assembly 40 is fixed between the heat insulation member 50 and the first door body 10 (taking the first door body 10 as an example), which can ensure that the heat of the heating assembly 40 is efficiently transferred to the seal 30, and then a good defrosting effect is generated. At the same time, the heat insulation member 50 can also wrap the heating assembly 40 inside, ensuring the aesthetics of the first door body 10 and the second door body 20.

[0050] It should be noted here that the material of the heat insulation member 50 can be any one of fiberglass, aerogel felt, and metal foam, and any structure that can produce a good cold and heat insulation effect is within the scope of disclosure and protection of this embodiment. Further, the heat insulation member 50 is detachably connected to both the first door body 10 and the second door body 20. The detachable connection method can facilitate subsequent maintenance and component replacement, and has strong operability.

[0051] As Figure 1 shown, handles 70 are provided on the sides of the first door body 10 and the second door body 20 facing away from the low-temperature chamber. When it is necessary to open or close the first door body 10 or the second door body 20, just pull the handle 70, which is convenient for opening and closing.

[0052] In summary, using the double-door structure and the test chamber in this embodiment can not only defrost the seal 30, but also improve the aesthetics and the user experience of the test personnel.

[0053] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
