Technical Field

[0001] The utility model relates to the field of incubators, and particularly to an incubator for uniformly regulating temperature and humidity. Background Art

[0002] Incubators are widely used in scientific research departments such as medical and health, pharmaceutical industry, biochemistry, industrial production, and agricultural science. Their main function is to cultivate various microorganisms or organisms such as tissues and cells.

[0003] When in use, the temperature and humidity of the incubator need to be controlled to meet the temperature and humidity requirements of the cultivation object. In order to make the temperature and humidity in the incubator uniform, it is necessary to make the internal air flow. However, the existing air flow methods are relatively simple and rough, and there are problems of uneven temperature and humidity around the four sides and corners of the incubator, and it is impossible to achieve a good effect of uniform temperature and humidity. Summary of the Utility Model

[0004] The utility model provides an incubator for uniformly regulating temperature and humidity, which solves the problem of uneven temperature and humidity around the four sides and corners of the existing incubator.

[0005] The technical solution of the utility model is realized as follows:

A front air flow upward cavity is formed between the front end of the partition and the front end of the inner container. A rear air flow upward cavity is formed between the rear end of the partition and the rear end surface of the inner container. A circulation fan is also included. The circulation fan is used to push the air flow to enter the side air flow downward cavities downward from both sides of the air flow collecting cavity, then blow horizontally into the inner container, and finally pass upward through the upper air through holes into the air flow collecting cavity from the front air flow upward cavity and the rear air flow upward cavity.

[0007] Furthermore, the partition is a solid plate or a hollow plate. Air inlets corresponding to the partition docking through holes are provided on the two side surfaces of the hollow plate. Air outlet holes are provided on the upper surface and / or the front and rear end surfaces of the hollow plate. Some of the side air through holes are docked with the air inlets or the side air through holes are only provided at the places docked with the air inlets.

[0008] Furthermore, the inner container includes a top plate. U-shaped air guiding walls are fixedly connected to both sides of the top plate. The opening of the U-shaped air guiding wall faces the box body.

[0009] Further, the U-shaped air guide wall includes a front end plate and a rear end plate, and the front end plate and the rear end plate are connected by a front side plate, and the side air vents are opened on the front side plate and / or the two front and rear end plates.

[0010] Further, a temperature regulating device and a humidity regulating device are further included. The temperature regulating device includes an evaporator, a compressor, a condenser and an expansion valve connected into a circulation loop through pipelines. The evaporator is located in the air flow collecting cavity. The humidity regulating device includes a humidifier, and the moisture outlet of the humidifier is located in the air flow collecting cavity.

[0011] Further, a rear box body fixedly connected to the rear part of the box body is further included. The compressor, the condenser, the expansion valve and the humidifier are all located in the rear box body, and an exhaust port for the condenser to discharge heat is opened on the rear box body.

[0012] Further, a temperature sensor and a humidity sensor are further arranged in the air flow collecting cavity.

[0013] Further, the number of the circulation fans is one, two, three or four. The circulation fans are installed in the middle, directly above or directly below the upper air through holes, or the circulation fans are installed on both sides of the air flow collecting cavity.

[0014] Further, horizontal outward concave partition slots are arranged on both side surfaces of the inner container, and both side ends of the partition are located in the partition slots. Alternatively, partition connection screw holes are opened on both side surfaces of the inner container, and the partition is fixedly connected to the partition connection screw holes by screws.

[0015] Further, partition connection screw holes are opened on both side surfaces of the inner container, and the partition is fixedly connected to the partition connection screw holes by screws.

[0016] Further, a heat-insulating box door that can be opened and closed is hinged to the front end of the box body.

[0019] Advantages of the present utility model: When the present utility model is in use, under the action of the circulation fan, the air flow enters the air flow aggregation cavity from the upper air through-hole, then enters the side air flow downward flow cavity downward from both sides of the air flow aggregation cavity, and then is horizontally blown into the inner container through the side ventilation holes or blown into the inner container through the upper surface or the front and rear surfaces of the partition board. Finally, the air flow flows upward through the front air flow upward flow cavity and the rear air flow upward flow cavity at the front and rear ends, and enters the air flow aggregation cavity again through the upper air through-hole, circulating in this way. Because the air flow is blown into the inner container from both sides of the inner container or the upper surface or the front and rear surfaces of the partition board, there are no dead corners at the two side edges of the inner container. After being blown into the inner container, it flows upward from the front and rear ends of the inner container and enters the air flow aggregation cavity, so there are also no dead corners at the front and rear edges of the inner container, thus ensuring that the temperature and humidity inside the inner container are uniform and there are no dead corners.
