Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a high and low temperature test chamber with dehumidification function. Background Technology
[0002] In modern scientific research and industrial production, high and low temperature test chambers are widely used in industries such as electronics, aerospace, and automobile manufacturing as key equipment for simulating different temperature and humidity environments. They are used to test the performance and reliability of materials and products under extreme conditions.
[0003] Regarding the dehumidification function, traditional test chambers mostly rely on evaporator condensation for dehumidification. After the condensate adheres to the inner wall of the chamber, it is easy to evaporate again or drip onto the surface of the test sample. This not only leads to low dehumidification efficiency and large fluctuations in humidity inside the chamber, but may also cause contamination or damage to the sample, affecting the accuracy of the test results. Therefore, we propose a high and low temperature test chamber with dehumidification function to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a high and low temperature test chamber with dehumidification function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high and low temperature test chamber with dehumidification function includes: a high and low temperature test chamber body, a hinged closed door on one side of the high and low temperature test chamber body, a three-color warning light and a controller on one side of the high and low temperature test chamber body, an exhaust pipe connected to the top of the high and low temperature test chamber body, a U-shaped scraper slidably installed on the inner wall of the high and low temperature test chamber body, a support plate fixedly installed on one side of the high and low temperature test chamber body, a fan installed at the bottom of the support plate, a filter screen installed inside the air inlet of the fan, and a filter screen installed inside the air outlet of the fan. The high and low temperature test chamber is equipped with a heating plate. Inside the chamber, there is a water collection tray and a filter plate. A wind guide assembly is located on top of the filter plate. The wind guide assembly includes a support base, a moving block, and a waterproof motor. A baffle plate is hinged to the top of the support base. A lead screw is fixedly installed on the output end of the waterproof motor. The moving block is threaded to the outside of the lead screw. Guide rods are fixedly installed on both sides of the moving block. The two sets of guide rods are slidably installed inside the support base. Connecting rods are hinged between the outside of the two sets of guide rods and the two sides of the baffle plate.
[0006] Preferably, three sets of limiting rods are fixedly installed inside the high and low temperature test chamber body, and the U-shaped scraper is slidably installed on the outside of the three sets of limiting rods. A drive motor is fixedly installed on the top of the high and low temperature test chamber body, and a reciprocating screw is fixedly installed on the output end of the drive motor. The U-shaped scraper is threadedly connected to the outside of the reciprocating screw. One side of the water collection tray is connected to the overflow port and the water discharge port of the water collection tray. The main power supply is provided on the right side of the high and low temperature test chamber body. The humidification tank discharge port and the automatic water filling port are provided on the rear bottom of the high and low temperature test chamber body. Four sets of universal wheels are provided on the bottom of the high and low temperature test chamber body.
[0007] Preferably, a door handle is provided on one side of the closed door, and a viewing window is provided inside the closed door.
[0008] Preferably, the air outlet of the fan is connected to one side of the high and low temperature test chamber body, the support base is set on the filter plate, and the movable block is slidably installed on the top of the support base.
[0009] Preferably, guide grooves are provided on both sides of the support base, and the two sets of guide rods are slidably installed in the corresponding guide grooves.
[0010] Preferably, the overflow outlet and the drain outlet of the water collection pan are both connected to one side of the high and low temperature test chamber body, and the filter plate is arranged above the water collection pan.
[0011] In this invention, a high and low temperature test chamber with dehumidification function is provided. By setting up a closed door, a door handle, and a viewing window, it is convenient for operators to open and close the closed door and to observe the state of the test samples inside the chamber. By setting up casters, it is convenient to move and adjust the position of the high and low temperature test chamber body, so that the high and low temperature test chamber body can be flexibly arranged in different test sites. The three-color warning light displays green when the high and low temperature test chamber body is operating normally, and displays yellow or red when abnormal temperature, humidity, or equipment failure occurs. The controller facilitates timely inspection and handling by the staff.
[0012] This invention relates to a high and low temperature test chamber with dehumidification function. By setting a main power supply, it protects the safety of operators and the equipment itself from damage. By setting a humidification tank drain outlet and an automatic water inlet, it ensures stable humidification and maintains precise humidity control within the test chamber. A drive motor rotates a reciprocating screw, and a U-shaped scraper is threaded to the outside of the screw. Guided by three sets of limit rods, the U-shaped scraper sweeps water droplets adhering to the inner wall of the high and low temperature test chamber downwards, through a filter plate, and into a water collection pan. When the water in the pan reaches the overflow outlet, it is automatically discharged. At this point, operators can open the drain outlet of the water collection pan to clean the water, preventing condensate from adhering to the inner wall of the chamber and potentially evaporating back into the air, affecting dehumidification efficiency and humidity control accuracy. This design automates the drainage process, eliminating the need for frequent manual checks of the water level in the collection pan and reducing the workload of operators. This utility model features a reasonable structural design. By incorporating a fan and a heating plate, outside air is filtered through a filter and heated by the heating plate before entering the high and low temperature test chamber. The hot air flows within the chamber, and through the coordinated action of a waterproof motor, lead screw, moving block, guide rods, and guide grooves, the moving block drives two sets of guide rods to move horizontally along the direction of the lead screw. This, in turn, causes a baffle plate to swing at the hinged joint at the top of the support base via a connecting rod. This, in conjunction with the hot air delivered by the fan, alters the direction and path of airflow, resulting in more uniform air distribution within the test chamber. The air is evenly distributed, and the exhaust pipe helps to expel the moisture-laden gas from the high and low temperature test chamber. After the dehumidification inside the test chamber is completed, the waterproof motor keeps the baffle horizontal. Then, the closed door is opened, the workpiece to be tested is placed on the baffle, and the closed door is closed to conduct the test. With the air evenly distributed, the moisture-laden gas can be expelled from the test chamber more efficiently, and the humid air can be expelled in time to avoid the accumulation of moisture inside the chamber. This further ensures the precise control of humidity inside the test chamber and ensures that the test can be carried out smoothly under the set humidity conditions. Attached Figure Description

Guide rods 806 are fixedly installed on both sides of the moving block 805. The two sets of guide rods 806 are slidably installed in the support base 801. Connecting rods 808 are hinged between the outside of the two sets of guide rods 806 and the two sides of the baffle plate 802.
[0017] In this embodiment, three sets of limiting rods 15 are fixedly installed inside the high and low temperature test chamber body 1. The U-shaped scraper 13 is slidably installed on the outside of the three sets of limiting rods 15. A drive motor 12 is fixedly installed on the top of the high and low temperature test chamber body 1. A reciprocating screw 14 is fixedly installed on the output end of the drive motor 12. The U-shaped scraper 13 is threadedly connected to the outside of the reciprocating screw 14. An overflow port 5 and a drain port 6 of the water collection pan 4 are connected to one side of the water collection pan. A main power supply 20 is provided on the right side of the high and low temperature test chamber body 1. A humidification tank drain port 21 and an automatic water filling port 22 are provided on the rear bottom of the high and low temperature test chamber body 1. Four sets of universal wheels 2 are provided at the bottom of the high and low temperature test chamber body 1 to ensure that the U-shaped scraper always maintains a vertical posture during the reciprocating motion and avoids blind spots caused by tilting.
[0018] In this embodiment, a door handle is provided on one side of the closed door 3, and a viewing window is provided inside the closed door 3 to provide reliable protection for real-time monitoring.
[0019] In this embodiment, the air outlet of the fan 17 is connected to one side of the high and low temperature test chamber body 1, the support base 801 is set on the filter plate 7, and the moving block 805 is slidably installed on the top of the support base 801, which significantly reduces the equipment maintenance cost.

[0021] In this embodiment, the overflow port 5 and the water outlet 6 of the water collection pan are both connected to one side of the high and low temperature test chamber body 1, and the filter plate 7 is set above the water collection pan 4 to effectively prevent excessive water accumulation.
[0022] In this embodiment, during use, the main power supply 20 is set to protect the safety of the operator and the equipment itself from damage. The humidification tank outlet 21 and the automatic water inlet 22 are set to ensure stable humidification and maintain precise control of humidity inside the test chamber. By starting the drive motor 12, the reciprocating screw 14 is rotated. The U-shaped scraper 13 is threaded to the outside of the reciprocating screw 14. Under the guidance of the three sets of limit rods 15, the U-shaped scraper 13 scrapes the water droplets attached to the inner wall of the high and low temperature test chamber 1 downwards through the filter plate 7 and into the water collection pan 4. When the water in the water collection pan 4 reaches the overflow port 5, it will be automatically discharged.

After the dehumidification inside the high and low temperature test chamber body 1 is completed, the waterproof motor 803 is started to make the baffle 802 horizontal, then the closed door 3 is opened to place the workpiece to be tested on the baffle 802, and then the closed door 3 is closed to carry out the test. The closed door 3 is installed on one side of the high and low temperature test chamber body 1 by hinge. The door handle makes it easy for operators to open and close the closed door 3. The viewing window makes it easy to observe the status of the test samples inside the chamber. The casters 2 are installed at the bottom of the high and low temperature test chamber body 1, which facilitates the movement and position adjustment of the high and low temperature test chamber body 1, so that the high and low temperature test chamber body 1 can be flexibly arranged in different test sites. The tri-color warning light 10 displays green when the high and low temperature test chamber body 1 is operating normally, and displays yellow or red when there are abnormalities in temperature or humidity, or equipment failure.
