Detailed Description

The invention is further described with reference to the following figures and examples:

the first embodiment is as follows: referring to fig. 1-4, an anti-condensation incubator comprises an outer box body 1 and a box body inner container 2 in the outer box body 1, wherein the box body inner container 2 comprises a heat preservation layer and a heating film layer, a working area 3 is arranged in the box body inner container 2, a water accumulation disc 4 is arranged at the bottom of the box body inner container 2, a condensation area 5 is arranged on the box body inner container 2 and is communicated with the outer box body 1 and the working area 3, a guide plate 6 is covered on the inner side of the condensation area 5 correspondingly, the guide plate 6 is a condensation point, and condensation is guided into the water accumulation disc 4.

As shown in fig. 1, an air circulation system is further arranged in the box liner 2 and comprises an air duct 7 and a fan 8, the air duct 7 is arranged at the top of the box liner 2 and extends to the bottom of the box liner 2 along the wall of the box liner in the condensation area 5, the fan 8 is positioned in the air duct 7 and is arranged at the top of the box liner 2, air in the working area 3 enters the air duct 7 from the fan 8 and is discharged from an air duct outlet close to the bottom of the box liner 2 after passing through the condensation area 5 and then enters the working area 3 again, and therefore air circulation is formed. The air duct 7 is matched with the condensation area 5, and the active condensation mode is adopted to maintain higher relative humidity in the working area and prevent condensation 13 from being generated everywhere. Air in the working area 3 is forced and directionally flows into the air channel 7 in a forced convection mode and then flows through the condensation area 5 to generate condensation, so that the relative humidity of the air in the working area 3 is reduced to an acceptable level.

The air deflector 6 is a hollow structure with a plurality of diversion holes 9, the diversion holes 9 penetrate from the top to the bottom of the air deflector 6 along the extension direction of the air deflector, and partial air flow in the air duct 7 is discharged after passing through the diversion holes 9. The ventilation area of the shunting holes 9 accounts for less than 5% of the ventilation area of the whole air duct 7. 2% can be selected, and through repeated tests in experiments, 2% of airflow flows through the condensation area 5 to complete condensation 13, so that the relative humidity of the working area 3 can be better maintained to reach an acceptable level, and no condensation 13 is generated in the working area 3; and 2% air current flows through this region and produces the cooling, flows to workspace 3 bottom after the air current outflow section mixes with 98% air current, and the relative humidity and the temperature of air current all decline to this moment (for in workspace 3, this air current temperature and humidity are lower relatively, so can not produce the condensation in workspace 3), flow to workspace center and top after with bottom high temperature air neutralization again, can be better realize aqueous vapor 14 circulation, maintain workspace temperature and humidity homogeneity.

As shown in fig. 2 and 4, the flow guide plate 6 is composed of a flow guide plate 11 covering the condensation area 5 and a flow diversion main plate 10 located outside the flow guide plate 11, the flow guide plate 11 is composed of a vertical plate and a bottom inclined plate, and the flow diversion main plate 10 is in superposition fit with the flow guide plate 11. The guide plate 6 is matched with the condensation area 5 for arrangement, so that the generated condensation 13 directly flows into the water collecting disc 4 for reuse, the waste of water in the water collecting disc 4 is reduced, and the frequency of adding water is reduced. The incubator is in normal use, the door opening frequency is reduced as much as possible, and the control of temperature and humidity precision in the incubator working area is greatly influenced by opening the door every time.

As shown in fig. 2, the air duct 7 is formed by wrapping an air deflector 12, an air inlet is arranged on the air deflector 12 corresponding to the fan 8, the air deflector 6 is located on the inner side of the air deflector 12, and an air outlet is arranged above the air deflector 12 close to the water collecting tray 4. In the present embodiment, the condensation area 5 is disposed in the air duct 7, and does not directly affect the temperature of the working area 3, and the generated condensation 13 is not directly exposed in the working area 3. Compared with the mass incubator in the market, the dew condensation area 5 (namely the cold spot area) is arranged in the working area 3, so that the temperature in the working area 3 can be directly influenced, and the constant temperature performance of the incubator can be directly influenced; the condensation 13 is directly exposed in the working area 3, and if the treatment is not carried out in time, substances such as bacteria bred in the condensation can directly pollute the culture sample.

The invention combines a unique air duct design through the drainage fan at the top of the inner container of the incubator to ensure that the air flow in the incubator flows directionally, and the air duct 7 is internally provided with the shunting holes 9 to ensure that the air flow can be shunted accurately. The main characteristics and effects are as follows:

1. realize the incubator workspace 3 through accurate reposition of redundant personnel and prevent the condensation. Because the condensation zone 5 (non-working zone) is cooler, the airflow through this zone will have a certain amount of cooling, which is detrimental to the thermostatic control of the working zone 3. And utilize the reposition of redundant personnel hole 9 on the reposition of redundant personnel mainboard 10 in wind channel 7, only make 2% air current flow through condensation area 5, the condensation 13 that produces flows to ponding dish 4 through the drainage board again and recycles, realizes aqueous vapor 14 circulation to can guarantee to be in the high humidity and can not produce the state of condensation 13 in the workspace 3, and can not lead to the fact the influence to the workspace 3 temperature.

2. The temperature and the humidity in the box are uniformly distributed. Through the directional induced circulation of the air flow, the bottom of the box body can be mixed with the air flow at the upper part, so that the temperature and the humidity in the box are uniformly distributed.
