Description

Technical Field

[0001] The utility model belongs to the technical field of climate environment experimental equipment, and in particular relates to a single-layer glass defrosting device and a climate environment test box. Background Art

[0002] Climate environment test chamber is a kind of experimental equipment that simulates various climate environments and is used to test the performance and tolerance of materials, products or organisms under various environmental conditions such as temperature, humidity, light, wind speed, etc. It is widely used in scientific research, quality inspection, production and other fields, especially in new material research and development, product quality control, agricultural research and so on.

[0003] When the climate environment test chamber is conducting a low-temperature test, the glass side of the glass observation window on the test chamber door is placed in a humid environment indoors, which can easily cause frost and condensation on the glass surface, affecting the effect of the light beam passing through the glass during the light wave test.

[0004] The Chinese patent with the authorization announcement number CN219150159U discloses a rapid temperature change test box with an automatic defrosting device. The rapid temperature change test box is a kind of climate environment test box, which includes a box body and a drying and defrosting mechanism. The drying and defrosting mechanism includes an air inlet pipe, a mounting plate, an exhaust fan, an air outlet pipe, a drying component and a filter component. The mounting plate is arranged on the outer wall of the box body, and the exhaust fan is arranged on the mounting plate. One end of the air inlet pipe is connected to the outer wall of the top of the box body, and the other end is connected to the exhaust fan; one end of the air outlet pipe is connected to the outer wall of the bottom of the box body, and the other end is connected to the exhaust fan. The above-mentioned rapid temperature change test box absorbs the air in the box body through the exhaust fan, enters the air inlet pipe, and is dried and dehumidified by the desiccant to remove moisture and prevent the moisture from condensing into frost. A heating wire is arranged in the butt joint pipe at the air outlet pipe to heat the air to make the air drier. The dried air returns to the box body again, and this is repeated to accelerate the air flow, remove moisture in the air and avoid frost. This method can effectively avoid frost, but it requires the use of an exhaust fan to extract and supply air to the box, and its defrosting effect is limited by the size of the entire box and the power of the exhaust fan.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Embodiment 1 of the single-layer glass defrosting device provided by the utility model:

[0033] like Figure 1 and Figure 2 As shown, the single-layer glass defrosting device is used to be installed outside the door 11 of the climate environment test box, and includes an isolation cover 1, a dry air generator 2, a controller and a humidity sensor 10. Among them, the isolation cover 1 is a rectangular parallelepiped structure, and the isolation cover 1 is made of stainless steel, such as Figure 3 and Figure 4 As shown, it has an upper flap 3 and a lower flap 4, and both the upper flap 3 and the lower flap 4 are provided with sealing gaskets 6. When installed, the isolation cover 1 is arranged outside the glass observation window 12 of the climate environment test box, and the upper flap 3 and the lower flap 4 are detachably fixed to the box door 11 by screws 5. Under the sealing of the sealing gasket 6, a sealed isolation drying chamber 7 is formed between the isolation cover 1 and the box door 11, and the outer surface of the glass observation window 12 is located in the isolation drying chamber 7.

[0034] The isolation cover 1 is provided with an air inlet 8 and an air outlet 9, wherein the air inlet 8 is arranged at the lower side of the isolation cover 1, and the air outlet 9 is arranged at the upper side of the isolation cover 1. The outlet of the dry air generator 2 is connected to the air inlet 8 to introduce dry air into the isolation drying chamber 7. The dry air generator 2 is a prior art, which is a device for removing moisture from the air by physical or chemical methods, and its specific structure and working principle are not described in detail here. The humidity sensor 10 is located in the isolation drying chamber 7, and the door 11 is provided with a mounting groove for mounting a glass observation window 12. The temperature sensor is fixed in the mounting groove and close to the glass observation window 12, and is used to detect the air humidity in the isolation drying chamber 7.

[0035] The controller is connected to the humidity sensor 10 and is connected to the dry air generator 2 for controlling the dry air generator 2 to start when the humidity sensor 10 detects that the air humidity in the isolated drying chamber 7 is lower than a set value. In this embodiment, the set value is 10% RH.

[0036] During the test, when the humidity sensor 10 detects that the humidity in the isolated drying chamber 7 is lower than 10% RH, the controller controls the dry air generator 2 to start, and the dry air generator 2 introduces dry air into the dry isolation chamber through the air inlet 8, so that the glass observation window 12 is in a relatively dry environment to prevent frost and condensation. When conducting the light wave test, the light wave emitting device 13 is arranged in the isolated drying chamber 7, located on the outside of the glass observation window 12, and the light wave receiving device 14 is arranged on the inside of the glass observation window 12. The light beam 15 emitted by the light wave emitting device 13 passes through the glass observation window 12 and is projected toward the light wave receiving device 14. Since the glass observation window 12 will not be frosted or condensed, it will not affect the effect of the light beam 15 passing through the glass observation window 12.

[0037] The single-layer glass defrosting device of the utility model is arranged on the outside of the door 11 of the climate environment test box. The isolation cover 1 only needs to cover the glass observation window 12. It is not limited by the size of the box body and does not need to use an exhaust fan. The size of the drying isolation room can be set according to the size of the glass observation window 12. The overall structure is simple and occupies little space.

[0038] Embodiment 2 of the single-layer glass defrosting device provided by the utility model:

[0039] The main difference between the embodiment 1 and the embodiment 1 is that in the embodiment 1, the isolation cover is a rectangular parallelepiped structure. In the present embodiment, the isolation cover adopts a spherical structure. Of course, the isolation cover is not limited to the above structure, and can also adopt an irregular shape structure as long as it can cover the glass observation window.

[0040] Embodiment 3 of the single-layer glass defrosting device provided by the utility model:

[0041] The main difference between it and Example 1 is:

[0042] In Example 1, the isolation cover has an upper turning edge and a lower turning edge, which is connected to the box door by screws to compress the sealing gasket to achieve sealing. In this embodiment, the isolation cover does not have an upper turning edge and a lower turning edge, and is directly welded to the box door during installation to achieve sealing.

[0043] The embodiment of the climate environment test box provided by the utility model:

[0044] The climate environment test box includes a box body, a box door with a glass observation window is connected to the box body, and a single-layer glass defrost device is provided outside the box door. The structure of the single-layer glass defrost device is the same as the structure in the above-mentioned embodiments of the single-layer glass defrost device, and will not be described in detail here.

[0045] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "upper", "lower", "inside", "outside" and other terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of this specification, which are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.
