Description

Technical Field

[0001] The utility model relates to the technical field of combined-use biochemical instruments, in particular to a condensation-proof carbon dioxide incubator based on semiconductor refrigeration. Background Art

[0002] The carbon dioxide incubator is an improvement on the ordinary cell culture incubator. It forms a growth environment similar to that of cells or tissues in the body in the incubator cavity, and can culture cells or tissues in vitro. The carbon dioxide incubator requires a stable temperature (37°C), a stable CO2 content (5%), and a high relative saturated humidity (≥90%). When the temperature of the local area inside the cavity is lower than the dew point temperature, condensation water will be generated. The generation of condensation water can easily cause the growth of microorganisms and contamination, which may lead to the failure of cell culture in the incubator.

[0003] In order to prevent possible contamination caused by condensed water in the incubator cavity, the carbon dioxide incubator is specially designed in structure so that condensed water only appears on the back wall of the incubator, above the water line of the water basin, and the condensed water can flow directly back to the water basin at the bottom of the inner cavity. In this way, the location, size and flow direction of the condensed water are controlled, and the incubator will not increase the possibility of contamination due to condensed water.

[0004] There is a problem with the above method. First, the inner cavity material is stainless steel, which is a low thermal conductivity material with a thermal conductivity coefficient of 13-16W / (m*K). The temperature difference between the condensation water collection area and other areas is low, and the condensation effect is not obvious. In addition, the artificially created condensation area is too large, and the condensation water is difficult to control to appear in a specific area. The incubator will increase the risk of contamination due to the appearance of condensation water. Utility Model Content

The inner cavity component 2 is arranged on the inner wall of the outer box body 1. The inner cavity component 2 is provided with an inner cavity opening connected to the opening of the outer box body 1. The box door component and the inner cavity component 2 form a closed working area 3. Culture dishes are placed in layers in the working area 3. An air circulation system is provided in the working area 3. The air circulation system can suck the airflow in the working area from bottom to top, and then discharge the airflow from top to bottom through the circulating air duct in the air circulation system, so that a circulating airflow is formed in the working area 3. The inner cavity component 2 is provided with a condensation area 5, which connects the outer box body 1 and the working area 3. A semiconductor refrigeration module 6 is provided in the condensation area 5. The airflow circulation system is connected to the condensation area 5. The airflow flows through the condensation area 5. The semiconductor refrigeration module 6 cools the airflow into a condensation condition and generates condensed water. The airflow circulation system is provided with an exhaust port, and a water basin 4 is provided at the exhaust port. The airflow circulation system is used to condense and circulate the airflow in the working area. The condensed water 13 flows downward into the water basin 4. The water in the water basin 4 evaporates to form water vapor 14, and the airflow circulation system then inhales the water vapor for the next cycle.

[0018] Specifically, the air circulation system includes a top air duct 9, a fan 10, a back air duct 8 and a guide plate 7. The top air duct 9 is installed at the top of the inner cavity component 2.

The back air duct 8 is arranged on the inner wall of the inner cavity component 2. The top of the back air duct 8 is connected to the top air duct 9. The airflow enters the back air duct 8 through the top air duct 9. The guide plate 7 is arranged at the exhaust port of the back air duct 8. One side of the guide plate 7 is connected to the inner wall of the back air duct 8, and the other side of the guide plate 7 is tilted downward, which can guide the condensed water to flow into the water basin 4 along the guide plate 7.

[0019] Specifically, the inner cavity component 2 is provided with a thermal insulation cotton layer and a heating layer. The heating layer can heat the gas in the working area and adjust the temperature in the working area.

[0020] Specifically, the door assembly includes an inner door 11 and an outer door 12, wherein the inner door 11 is made of glass material. When the growth state of the cultured bacteria in the culture dish needs to be observed, the outer door 12 can be opened.

The temperature of the area is fed back to the control board in real time, and dynamic cooling is achieved by adjusting the current to always control the temperature difference of the air flow in the condensation area 5 and the working area 3 within a certain range.
