Description

Technical Field

[0001] This application relates to the field of testing laboratory technology, and more particularly to a temperature and humidity environment testing laboratory. Background Technology

[0002] An environmental testing chamber is a device used to simulate various environmental conditions such as temperature and humidity. It is widely used in product development, quality control, and performance testing in fields such as textiles, electronics, chemicals, and aerospace. In the textile industry, it is often necessary to place fabric samples in extreme temperature and humidity environments (such as high temperature and high humidity, low temperature and low humidity) to accurately test key indicators such as thermal insulation performance and mechanical properties (such as tension and tensile strength).

[0003] A search revealed that Chinese patent CN222606410U discloses a constant temperature and humidity test chamber with a protective structure. This chamber can promptly collect and clean condensate from the inner wall of the top side of the main body, preventing condensate from dripping onto the surface of the test items and ensuring the accuracy of the tests. However, when using this device, the partition of the storage chamber must first be opened to connect the storage chamber to the inner cavity of the main body of the constant temperature and humidity test chamber. This allows the collection bucket and scraper to extend from the side wall and move to the top of the chamber, which significantly disrupts the temperature and humidity balance inside the test chamber. Although the control system attempts to compensate, this impact is severe and localized, and the compensation process is very slow and produces overshoot. As a result, the environment inside the chamber remains in a state of violent vibration and unevenness for a long period of time, affecting the test results. Therefore, a temperature and humidity environment testing chamber is proposed to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a temperature and humidity environment testing chamber:

[0027] A temperature and humidity environment testing chamber includes: a testing chamber body 1, i.e. a constant temperature and humidity test chamber, which is existing technology and will not be described in detail here; the inner surface of the top wall of the testing chamber body 1 is constructed to guide the condensed water to its side through a guide surface 101; a water collection tank 2, which is fixedly connected to the inner wall of the testing chamber body 1 and corresponds to the end of the guide surface 101, for collecting the condensed water guided by the guide surface 101; and a self-sealing drain pipe 3, which is disposed inside the testing chamber body 1, with one end fixed and connected to the bottom of the water collection tank 2, and the other end extending to the outside of the testing chamber body 1.

[0028] Specifically, the guide surface 101 actively guides the condensate from the top wall, preventing disorderly dripping. The condensate is collected by the collection tank 2, and the self-sealing drain pipe 3 automatically discharges the condensate without external power or control, ensuring reliable isolation between the atmosphere inside and outside the main body of the testing chamber 1. This solves the problem of condensate dripping interfering with the test in the temperature and humidity environment testing chamber, while ensuring the airtightness of the main body of the testing chamber 1 and the stability of the temperature and humidity field.

[0029] The self-sealing drain pipe 3 includes a vertical descending section 301, a first U-shaped pipe section 302, a second U-shaped pipe section 303, and an output section 304. A water seal 305 is installed inside the first U-shaped pipe section 302, and the output section 304 extends to the outside of the main body 1 of the testing chamber. By setting the first U-shaped pipe section 302 and the water seal 305, physical sealing is achieved by utilizing the water stored inside. By setting the vertical descending section 301, gravity can be used to accelerate drainage. The second U-shaped pipe section 303 acts as a buffer and prevents external airflow disturbance. By setting the output section 304, it is ensured that the condensate is finally discharged outside the box, thereby ensuring a smooth drainage process. Moreover, the water seal 305 can be automatically restored after drainage, improving the sealing performance.

[0030] The guide surface 101 is a plane that slopes downward from the top wall to the side wall inside the main body 1 of the testing chamber. The guide surface 101 is a smooth plane, which can effectively reduce water flow resistance and allow condensate to slide into the water collection tank 2 more quickly and smoothly, thus improving drainage efficiency.

[0031] A horizontal partition 4 is fixedly connected to the inner wall of the main body 1 of the testing chamber. The horizontal partition 4 divides the inner cavity of the main body 1 of the testing chamber into an upper testing cavity 102 and a lower equipment cavity 103. The horizontal partition 4 is used for functional zoning, and auxiliary equipment is placed in the equipment cavity 103 to physically isolate it from the testing cavity 102 where the sample is placed. This prevents the vibration and heat generated during equipment operation from being transferred to the testing area, improves the stability of the testing environment, and ensures the accuracy of temperature and humidity control and mechanical / thermal insulation test results. The horizontal partition 4 is made of thermal insulation material.

[0032] A boss 5 is fixedly connected to the upper surface of the horizontal partition 4, and a shock-absorbing pad 6 is fixedly connected to the upper surface of the boss 5. This is used to place mechanical testing instruments or thermal insulation testing instruments. By setting the boss 5, a rigid mounting platform higher than the horizontal partition 4 is provided. By setting the shock-absorbing pad 6, the minor vibrations transmitted from the equipment cavity 103 through the horizontal partition 4 are further isolated, ensuring that the precision mechanical testing instruments or thermal insulation testing instruments placed on it are not disturbed, and can collect more accurate data, thereby improving the testing accuracy.

[0033] A vertical partition 7 is fixedly connected to the inner bottom wall of the equipment cavity 103 to isolate the self-sealing drain pipe 3. By setting the vertical partition 7, an independent isolation space is created for the self-sealing drain pipe 3 in the equipment cavity 103, avoiding interference or damage to the self-sealing drain pipe 3 that may be caused by personnel's daily maintenance operations on equipment such as compressors and fans, and protecting its integrity and reliability.

[0034] The bottom of the water collection tank 2 is provided with a drain outlet 201 that is connected to the self-sealing drain pipe 3. The inner bottom wall of the water collection tank 2 is fixedly connected with a guide seat 202 that slopes downward from the end of the water collection tank 2 toward the drain outlet 201. By setting the guide seat 202, it is ensured that there are no dead corners for water accumulation inside the water collection tank 2. All the condensate collected here can be completely guided to the drain outlet 201 under the action of gravity and finally discharged through the self-sealing drain pipe 3. This avoids water remaining in the water collection tank 2 and evaporating, which would repeatedly affect the humidity inside the chamber, or freezing and clogging due to low temperature testing, thus ensuring the long-term effectiveness and stability of the drainage system.

[0035] The front of the main body 1 of the testing chamber is rotatably connected to an upper opening door 8 and a lower opening door 9. The upper opening door 8 corresponds to the testing chamber 102, and the lower opening door 9 corresponds to the equipment chamber 103. A transparent observation window 10 is provided on the upper opening door 8. By setting the upper opening door 8 and the lower opening door 9, independent access to the testing chamber 102 and the equipment chamber 103 can be achieved. The observation window 10 allows real-time observation of the internal test status without opening the upper opening door 8, further reducing interference with the internal environment.

[0036] The surface of the self-sealing drain pipe 3 is covered with an insulation pipe 11, which can effectively reduce the heat exchange between the self-sealing drain pipe 3 and the external environment.

[0037] Working Principle: When using this temperature and humidity testing chamber, the user first sets the required temperature and humidity through the control system of the main body 1 of the testing chamber. Then, the fabric sample to be tested is placed in the testing chamber 102 onto the testing equipment, such as a mechanical testing instrument or a holding testing instrument. The upper door 8 is then closed, and the equipment is started. The main body of the testing chamber begins to work, creating the set extreme temperature and humidity environment inside. Once the ambient temperature and humidity stabilize, the testing equipment is activated to test the fabric sample. During operation, when the temperature of the top wall inside the main body 1 of the testing chamber is lower than the air dew point temperature, water vapor will... Water condenses on the guide surface 101 of the inner top wall. The condensed water droplets slide down the inclined guide surface 101 and flow into the water collection tank 2 on the side. The water in the water collection tank 2 slides along the guide seat 202 and enters the self-sealing drain pipe 3 through the drain outlet 201 at the bottom. It is automatically discharged to the outside of the test chamber body 1 by gravity, realizing the automatic discharge of condensate and ensuring the reliable isolation of the atmosphere inside and outside the test chamber body 1. Thus, the temperature and humidity environment test chamber solves the problem of condensate dripping interfering with the test, while ensuring the airtightness of the test chamber body 1 and the stability of the temperature and humidity field.
