Description

Technical Field

[0001] The utility model relates to the technical field of test chambers, and more particularly to a high and low temperature humidity test chamber with rapid temperature rise and fall. Background Technique

[0002] A test chamber is the general term for products in the environmental testing industry, which simulates the natural climate environment within an effective space range. The test types include: high and low temperature humidity test chambers, xenon lamp aging test chambers, ultraviolet aging test chambers, box-type rain test chambers, rust preventive oils, drip devices, purification and clean storage cabinets, nitrogen storage cabinets, non-standard products, etc. Generally, in order to achieve the purpose of rapid temperature rise and fall, a compressor and other rapid refrigeration devices are installed inside a high and low temperature humidity test chamber.

[0003] After retrieval, the existing patent (publication number: CN218459539U) discloses a high and low temperature humidity test chamber with rapid temperature rise and fall. During its use, when the internal temperature of the high and low temperature humidity test chamber body drops, the water vapor inside the high and low temperature humidity test chamber body condenses into water droplets, adheres to the inner wall and descends, and then enters the water tank, and further enters the water storage tank through the water passing holes. When the high and low temperature inside the high and low temperature humidity test chamber body has not been switched, the L-shaped lifting plate blocks the water passing holes to prevent heat loss. When the temperature of the high and low temperature humidity test chamber body drops, the micro motor drives the lead screw to rotate, and then the L-shaped lifting plate rises, ensuring that the condensed water droplets of the water vapor can flow into the water storage tank, which can effectively remove the condensed water droplets inside the high and low temperature humidity test chamber body. Therefore, during heating, these water droplets will not be reheated, saving energy. However, the inventor found the following problems in the process of implementing the present utility model: in the above-mentioned high and low temperature humidity test chamber, when heating and cooling materials, they are all carried out inside the same chamber, and the temperature change is a gradual process, which results in more time consumption during the cold and heat switching, reducing the test efficiency, and more energy consumption during each conversion, causing waste of energy.

[0004] In view of this, the present utility model provides a high and low temperature humidity test chamber with rapid temperature rise and fall. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a high and low temperature humidity test chamber with rapid temperature rise and fall to solve the problems existing in the above background technique.

[0006] The utility model provides the following technical solution: a high and low temperature humidity test chamber with rapid temperature rise and fall, including a box body. Inside the box body, a heating chamber and a cooling chamber are respectively arranged from left to right. On the front surface of the box body, sealing doors are hinged corresponding to the heating chamber and the cooling chamber. The box body is respectively provided with a heating component and a humidifying component corresponding to the heating chamber, and a cooling component and a drainage component corresponding to the cooling chamber. A partition board is arranged between the heating chamber and the cooling chamber. On the left and right side surfaces of the partition board, placing plates are fixedly installed. Placing grooves are formed on the surfaces of the placing plates. The partition board is movably installed inside the box body, and the box body is provided with a turning component corresponding to the partition board;

[0007] The turning component includes a rotating shaft rotatably connected inside the box body. The partition board is fixedly installed on the surface of the rotating shaft. A driving box is fixedly installed at the top of the box body. The top end of the rotating shaft extends into the driving box and is fixedly installed with a gear disk. A hydraulic rod is embedded on the surface of the driving box. The telescopic end of the hydraulic rod extends into the driving box and is fixedly installed with a rack. The rack meshes with the gear disk.

[0008] Further, the heating component includes heating plates embedded at the top and bottom of the heating chamber. A temperature and humidity sensor is fixedly installed on the inner top wall of the heating chamber.

[0009] Further, the humidifying component includes a water tank fixedly installed on the left side of the box body. A delivery pump is embedded at the bottom end of the water tank. The liquid inlet end of the delivery pump is communicated with the inner cavity of the water tank. The liquid outlet end of the delivery pump is fixedly installed with a delivery pipe. The other end of the delivery pipe extends into the heating chamber.

[0010] Further, an electromagnetic valve and a flow meter are respectively fixedly installed on the surface of the delivery pipe.

[0011] Further, the cooling component includes a refrigerator fixedly installed on the right side of the box body. A refrigeration pipe is arranged on the surface of the refrigerator. The refrigeration pipe extends into the cooling chamber. A temperature sensor is fixedly installed on the inner top wall of the cooling chamber.

[0012] Further, the drainage component includes a drain pipe embedded in the lower right of the cooling chamber. The water outlet end of the drain pipe extends to the outside of the box body and is fixedly installed with two gate valves. The heights of the two gate valves are different, and a liquid level window is embedded on the surface of the drain pipe; By setting the drainage component, by switching the opening and closing of the two gate valves, it is possible to achieve the effect of discharging part of the water body from the inside of the cooling chamber while always keeping the inside of the cooling chamber airtight.

[0013] Further, an inclined surface is fixedly installed on the inner bottom wall of the cooling chamber, and the low position end of the inclined surface faces the drain pipe; By setting the inclined surface, the effect of guiding the water body can be achieved.

[0014] Furthermore, the inner walls of the heating chamber, the cooling chamber and the surface of the partition plate are all provided with a heat insulation layer; by providing the heat insulation layer, the heat preservation effect of the heating chamber and the cooling chamber can be improved.

[0015] Technical effects and advantages of the utility model:

[0016] 1. The utility model places the test material inside the storage slot of the storage plate, and uses the partition plate to separate the heating chamber and the cooling chamber. The material inside the heating chamber can be heated by the heating component, the humidity inside the heating chamber can be adjusted by the humidifying component, and the material inside the cooling chamber can be cooled by the refrigeration component. When in use, the rack is driven to move by the hydraulic rod, and the rotating shaft is driven to rotate based on the meshing of the rack and the gear plate, so that the partition plate can be swapped, so that the position of the material can be quickly switched, so as to achieve the purpose of quickly heating and cooling the material. The test efficiency is high, and the heating chamber and the cooling chamber are independent of each other, and there is no need to drastically adjust the temperature inside the heating chamber and the cooling chamber during the switching process, thereby saving energy loss.

[0017] 2. In the utility model, when the material is transferred from the inside of the heating chamber to the inside of the cooling chamber, due to the decrease in temperature, part of the moisture on the surface of the material will condense into water and flow to the bottom side of the cooling chamber. By setting two gate valves with different heights, the gate valve on the bottom side is in a normally closed state, and the gate valve on the top side is in a normally open state. In the initial stage of switching the material from the heating chamber to the cooling chamber, part of the water droplets will gather to the inside of the drain pipe under the action of the inclined surface and stay above the gate valve on the bottom side. In the middle stage of refrigeration, the gate valve on the top side is closed and the gate valve on the bottom side is opened, and the water in the drain pipe will be discharged to the outside. If the water in the drain pipe condenses into ice cubes, it can gradually melt into water and be discharged to the outside at room temperature, thereby finally achieving the effect of discharging the water and avoiding the existence of too much water, which leads to more energy consumption when heating the subsequent materials.

[0024] Referring to Figures 1-4 , the present utility model provides a high and low temperature humidity test chamber with rapid temperature rise and fall, including a box body 1. A heating chamber 3 and a cooling chamber 4 are respectively arranged in the box body 1 from left to right. Sealing doors 2 are respectively hinged on the front surface of the box body 1 corresponding to the heating chamber 3 and the cooling chamber 4. The box body 1 is respectively provided with a heating assembly and a humidifying assembly corresponding to the heating chamber 3.

[0025] The box body 1 is respectively provided with a cooling assembly and a drainage assembly corresponding to the cooling chamber 4. A partition board 5 is arranged between the heating chamber 3 and the cooling chamber 4. Placing boards 6 are fixedly installed on the left and right side surfaces of the partition board 5. Placing grooves are formed on the surfaces of the placing boards 6.

[0026] The heating assembly includes heating plates 12 embedded in the top and bottom of the heating chamber 3. A temperature and humidity sensor 13 is fixedly installed on the inner top wall of the heating chamber 3.

[0027] By energizing the heating plates 12, the inside of the heating chamber 3 can be heated, and the temperature can be monitored in real time through the temperature and humidity sensor 13.

[0028] The humidifying assembly includes a water tank 14 fixedly installed on the left side of the box body 1. A delivery pump 15 is embedded at the bottom end of the water tank 14. The liquid inlet end of the delivery pump 15 is communicated with the inner cavity of the water tank 14. The liquid outlet end of the delivery pump 15 is fixedly installed with a delivery pipe 16. The other end of the delivery pipe 16 extends into the heating chamber 3.

[0029] By starting the delivery pump 15, the water inside the water tank 14 is added into the heating chamber 3 through the delivery pipe 16. The water volatilizes at high temperature, which can achieve the purpose of increasing the humidity inside the heating chamber 3. By using the temperature and humidity sensor 13, the humidity can be monitored in real time.

[0030] The surface of the delivery pipe 16 is fixedly installed with a solenoid valve and a flow meter 17 respectively.

[0031] Through the solenoid valve, the on-off of the delivery pipe 16 can be controlled. Through the flow meter 17, it is convenient to control the amount of water transported inside the delivery pipe 16, and it is convenient to adjust the humidity inside the heating chamber 3.

[0032] The cooling component includes a refrigerator 18 fixedly installed on the right side of the box body 1. The surface of the refrigerator 18 is provided with a cooling pipe 19, and the cooling pipe 19 extends into the cooling chamber 4. The inner top wall of the cooling chamber 4 is fixedly installed with a temperature sensor 20.

[0033] By energizing the refrigerator 18, the purpose of cooling the inside of the cooling chamber 4 can be achieved by using the cooling pipe 19.

[0034] The partition plate 5 is movably installed inside the box body 1, and the box body 1 is provided with a turning component corresponding to the partition plate 5.

[0035] The turning component includes a rotating shaft 7 rotatably connected inside the box body 1. The partition plate 5 is fixedly installed on the surface of the rotating shaft 7. The top end of the box body 1 is fixedly installed with a driving box 8. The top end of the rotating shaft 7 extends into the driving box 8 and is fixedly installed with a gear disk 9. The surface of the driving box 8 is embedded with a hydraulic rod 10. The telescopic end of the hydraulic rod 10 extends into the driving box 8 and is fixedly installed with a rack 11. The rack 11 meshes with the gear disk 9.

[0036] When the utility model is in use, the whole device is pre-connected to an external power control system, and then the test materials are placed in the placement grooves of the placement plate 6. The heating chamber 3 and the cooling chamber 4 are separated by the partition plate 5. Through the heating component, the materials located inside the heating chamber 3 can be heated. Through the humidifying component, the humidity inside the heating chamber 3 can be adjusted. Through the refrigerating component, the materials inside the cooling chamber 4 can be cooled. When in use, the hydraulic rod 10 is driven to move the rack 11. Based on the meshing of the rack 11 and the gear disk 9 to drive the rotating shaft 7 to rotate, the partition plate 5 can be turned around, so that the positions of the materials can be quickly switched, so as to achieve the purpose of quickly heating and cooling the materials. The test efficiency is high. And for the heating chamber 3 and the cooling chamber 4, since the two are independent of each other, it is not necessary to make drastic adjustments to the temperatures inside the heating chamber 3 and the cooling chamber 4 during the switching process, thus saving energy loss.

[0037] The drainage assembly includes a drain pipe 21 embedded in the lower right of the cooling chamber 4. The water outlet end of the drain pipe 21 extends to the outside of the box body 1 and is fixedly installed with two gate valves 22. The heights of the two gate valves 22 are different, and a liquid level window 23 is embedded on the surface of the drain pipe 21.

[0038] The inner bottom wall of the cooling chamber 4 is fixedly installed with an inclined surface 24, and the low end of the inclined surface 24 faces the drain pipe 21.

[0039] It should be noted that when the material is transferred from the inside of the heating chamber 3 to the inside of the cooling chamber 4, due to the temperature drop, the moisture on the surface of the material will condense into water and partially flow to the bottom side of the cooling chamber 4. By setting two gate valves 22 with different heights, the bottom gate valve 22 is normally closed, and the top gate valve 22 is normally open. In the initial stage when the material is switched from the heating chamber 3 to the cooling chamber 4, some water droplets will converge into the inside of the drain pipe 21 under the action of the inclined surface 24 and stay above the bottom gate valve 22. In the middle stage of refrigeration, the top gate valve 22 is closed, and the bottom gate valve 22 is opened. The water inside the drain pipe 21 will be discharged to the outside. If the water inside the drain pipe 21 freezes into ice, it can gradually melt into water and be discharged to the outside at room temperature, finally achieving the effect of discharging water and avoiding the consumption of more energy when heating the subsequent materials due to the existence of too much water.

[0040] Heat insulation layers 25 are provided on the inner walls of the heating chamber 3 and the cooling chamber 4 and on the surface of the partition plate 5.

[0041] By setting the heat insulation layer 25, the heat preservation effects of the heating chamber 3 and the cooling chamber 4 can be improved.

[0042] Finally, it should be noted that in the drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other.
