Further, the lower part of the water collecting tank 26 is communicated with the water tank of the humidifier 4 through a water conveying pipe 27.
Further, the air-conditioning cabinet further comprises a partition 29, wherein the partition 29 is positioned below the spherical top plate 23, the partition 29 is fixedly connected with the inner box body 2, and a plurality of air holes 291 are formed in the partition 29.
Further, the box body structure further comprises a screen plate 24, a plurality of pairs of guide rails 28 are arranged in the inner box body 2, the guide rails 28 are fixedly connected with the inner box body 2, and the screen plate 24 is connected with the guide rails 28 in a sliding mode.
Further, the refrigeration part of the refrigeration device is installed in the refrigeration box 3, the heating device is installed in the heating box 7, and the dehumidifier 61 is an ultrasonic humidifier.
Further, the inner box body 2 is communicated with a safety valve 8 through a pipeline, and the safety valve 8 is communicated with the outside of the outer box body 1 through a pipeline. The safety valve 8 is used for exhausting air to the outside when the air pressure in the inner tank body 2 is too high.
Further, the inner box body 2 is provided with a third fan 20, the third fan 20 is communicated with the scavenging valve 9 through a pipeline, and the scavenging valve 9 is communicated with the outside of the outer box body 1 through a pipeline. The scavenging valve 9 is used for scavenging air or replenishing air into the inner casing 2.
Further, the inner box body 2 is rotatably connected with an inner box door 10. The door of the outer case 1 is not shown.
The working principle is as follows:
in operation, the inner box door 10 of the inner box body 2 is opened, the screen plate 24 is pushed into the guide rail 28 with the proper height, the sample is placed above the screen plate 24, and the inner box door 10 is closed. The refrigerating compartment 3, the humidifier 4, the three-way valve 5, the dehumidifier 61, the dry filter 62, and the heating compartment 7 are opened or closed according to the temperature and humidity required in the test compartment.
When the temperature and the humidity are required to be reduced and the humidity is increased, the refrigerating box 3 and the humidifier 4 are operated, and the dehumidifier 61, the dry filter 62 and the heating box 7 are closed. The second fan 22 operates to draw air in the inner casing 2 into the refrigeration compartment 3, and a refrigeration device (e.g., an evaporator of an air conditioning system) in the refrigeration compartment 3 exchanges heat with the air to cool the air. Then the air passes through the humidifier 4 to increase the humidity of the air, and the humidifier 4 using the ultrasonic principle does not need to heat and evaporate water, so that the influence on the temperature of the air is small. At this time, the three-way valve 5 communicates only the humidifier 4 and the dehumidifier 61, but does not communicate with the dry filter 62. After passing through the dehumidifier 61 and the heating box 7, the air is sucked into the inner box 2 by the first fan 21, and the air is uniformly discharged downwards from the air outlet 231 (the air outlet 231 is uniformly arranged in a circumferential manner), so that the environment around the sample is cooled and humidified. The air then passes through the meshes of the mesh plate 24, passes downward through the air holes 291, and is sucked by the second fan 22, thereby circulating the air. The air holes 291 on the partition 29 are uniformly distributed, so that the air flow can uniformly flow in the inner box 2. The cylindrical inner casing 2 also facilitates the flow of air.
When the temperature is required to be raised and the humidity is required to be reduced, the dehumidifier 61 and the heating tank 7 are operated, and the cooling tank 3 and the humidifier 4 are closed. The air is circulated, reduced in humidity in the dehumidifier 61, heated by a heating means (e.g., a heating wire) in the heating compartment 7, and then returned to the inner case 2 without passing through the filter drier 62. The speed of humidity reduction using the dehumidifier is slow, and if it is required to reduce the humidity rapidly, the three-way valve 5 may be adjusted to allow the air to pass through the desiccant filter 62, and the air is rapidly reduced in humidity in the desiccant filter 62. The dry filter 62 needs to be replaced in time after being used several times.
When the condensed water appears on the surface of the spherical top plate 23, water drops flow downward along the arc surface of the spherical top plate 23, drop into the annular water tank 25, and then flow into the water collecting tank 26 by gravity. When a certain amount of water is accumulated in the water accumulating tank 26, the duckbill valve 261 is opened by the pressure of the water, and the water flows downwards after passing through the duckbill valve 261 into the water collecting tank 262 and finally into the water tank of the humidifier 4, so that the waste water is utilized.
The present invention has been described above by way of example, but the present invention is not limited to the above-mentioned embodiments, and any modification or variation based on the present invention is within the scope of the present invention.
