Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a constant temperature and constant humidity apparatus used for tissue culture of plants.

(Prior Art) An example of a conventional constant temperature and constant humidity apparatus is shown in FIG.

The air in the constant temperature and constant humidity chamber 1 is cooled and dehumidified while being extracted by the ventilation duct 2 and flowing through the cooler 3. Next, in the process of passing through the reheater 4, it is reheated to a predetermined temperature. Then, it is energized by the ventilation fan 5, dusts, germs and the like contained in the air are removed in the process of passing through the filter 7 through the ventilation duct 6, and again flow into the constant temperature and humidity chamber 1. Then, after being made to have a predetermined humidity by being mixed with the water vapor generated in the humidifier 8 and sprayed from the nozzle 10 into the constant temperature and constant humidity chamber 1 through the steam pipe 9, it is guided to a plurality of rectifying plates 11 to obtain a constant temperature. It flows as a uniform flow in the constant humidity chamber 1.

(Problems to be Solved by the Invention) In the above-mentioned conventional constant temperature and humidity apparatus, since the water vapor sprayed from the nozzle 10 has a high degree of vapor saturation, when the surface temperature of the straightening vane 11 is low, dew condensation occurs on the surface. To do. Therefore,
In order to keep the humidity in the constant temperature and humidity chamber 1 constant, a rectifying plate is used.
There was a problem that the operating cost of the thermo-hygrostat increased because the vapor had to be sprayed in a large amount corresponding to the amount of dew condensation on the surface of 11.

Further, when dew condensation is formed on the surface of the current plate 11, various bacteria and the like are generated on the surface of the current plate 11, which causes a problem of proliferation.

(Means for Solving the Problems) The present invention has been proposed to solve the above problems, and its gist is to provide a humidifier for humidifying air in a constant temperature and constant humidity chamber and the constant temperature and constant temperature chamber. A constant temperature and humidity apparatus having a straightening plate for rectifying the air flow in a humid chamber, wherein a means for ejecting water vapor into the constant temperature and constant humidity chamber through the inside of the straightening plate is provided. .

(Operation) Since the present invention has the above-mentioned configuration, since the current plate is maintained at a high temperature by being heated by the water vapor passing through the inside thereof, the water vapor ejected into the constant temperature and humidity chamber is exposed to the surface of the current plate. There is no condensation on.

(Embodiment) One embodiment of the present invention is shown in FIGS. 1 and 2.

The steam pipe 9 is connected to each straightening plate 20. As shown in FIG. 2, each straightening vane 20 has a cavity 21 and a plurality of ejection ports.
Equipped with 22.

Then, the high-temperature steam generated in the humidifier 8 is absorbed by the steam pipe 9
Then, it enters the cavity 21 of the straightening vane 20 and is ejected from the ejection port 22 into the constant temperature and constant humidity chamber 1.

Other configurations are similar to those of the conventional one shown in FIG. 3, and corresponding members are designated by the same reference numerals.

Then, since the current plate 20 is heated by the high temperature steam passing through the cavity 21, the surface thereof is maintained at a high temperature, and therefore the water vapor ejected from the ejection port 22 into the constant temperature and humidity chamber is the surface of the current plate 20. There is no condensation on.

The flow straightening plate 20 only needs to be able to pass water vapor into the flow straightening plate 20, and therefore the size, shape and number of the flow straightening plate 20, the shape and size of the cavity 21, and the number and position of the jet outlets 22 can be set arbitrarily. .

(Effect of the Invention) In the present invention, since the means for ejecting water vapor through the interior of the current plate to the constant temperature and humidity chamber is provided, the current plate is maintained at a high temperature by being heated by the water vapor passing through it. The steam ejected into the constant temperature and humidity chamber does not condense on the surface of the current plate.

As a result, the amount of humidification is small, so the operating cost of the constant temperature and constant humidity device can be reduced, and it is possible to prevent the growth of germs on the surface of the straightening plate.
