Abstract

The invention discloses a temperature and humidity guaranteeing device of a biological culture box. The temperature and humidity guaranteeing device comprises an outer box, an inner box, a shutter, a shutter control motor, a temperature control air supply fan, a cold/hot air channel, a heating refrigerator set and an auxiliary fan set. The culture box is in a structure of nesting the inner box and the outer box; the outer box is subjected to heat insulation treatment; a sandwich layer space between the inner box and the outer box is used for stirring and neutralizing cold air and hot air until uniform temperature meeting a test requirement is obtained; the inner box is used for biological culture and mildew culture; the side wall of the inner box is in a similar shutter structure; the shutter is opened and closed under the control of the motor; before being controlled to supply air to a sandwich layer for temperature regulation, a system interacts with the shutter motor to close the shutter so as to shield external wind power interference; after the temperature and humidity of the sandwich layer completely meet the test requirement and keep uniform, the system turns the fan off and opens the shutter, and the side wall is opened to enable temperature and humidity conditions of the sandwich layer to slowly penetrate into an inner box space through natural flowing, so that windless and non-overshoot temperature and humidity adjustment is realized.

Description

The humiture ensuring equipment of bio-incubator

Technical field:

Biological culture technigue is a key areas of the biological scientific experiment in various countries always, the different categories of cultivating are different because of the tolerance to environment, method and accuracy requirement to the control of incubator environment are also different, and the mould case of wherein especially cultivating with spore is the highest to the control requirement of the condition such as humiture and wind speed in the case.

Background technology:

The problem that prior art exists: without the incubator of particular design and transformation, even if provide the required temperature and humidity conditions of mycotic culture also can keep for a long time, still be difficult in the case mildewing.

The problem reason: the temperature/humidity control method of existing incubator is continued to use the traditional hot switching technology of high-and-low temperature humid heat test box more, namely relies on the forced air supply convection type and cold air or hot gas are blown into reach refrigeration or heating purpose in the incubator, realizes temperature control.But air-supply itself produces very big destruction to spore growth, the small wind-force tiny spores at the initial stage aufwuchsplate that blows off that can will mildew; Simultaneously, although the mode of the cold and hot neutralization control of strong convection temperature finally satisfies the growth temperature (25 ℃/30 ℃) of mould, but local mistake cold or overheated (15 ℃/40 ℃) still can appear in the cold and hot gas action of forced stirring process, this temperature overshot tends to exceed the spore tolerance range, destroys the spore activity even directly kills spore.

Summary of the invention:

Get rid of the artificial interference of " directly air-supply " and " temperature overshot ", simulate to greatest extent the true environment of mould-growth with " natural convection " technology.Incubator adopts inside and outside two layer box body nesting structures, and outer container is done insulation, and mezzanine space is neutralized to the uniform temperature of test requirements document between the interior outer container for the stirring of cold and hot air; Interior case is used for biology or mycotic culture, the inner box side wall adopts similar shutter, and utilize the folding of electric machine control blinds, Controlling System between interlayer the air-supply temperature adjustment before, the system interlink grille motor is closed window shutter and is disturbed to shield extraneous wind-force, after temperature, humidity between interlayer reach test requirements document fully and keep evenly, the system closing fan is also opened window shutter, open sidewall makes the temperature and humidity conditions between interlayer slowly be penetrated into interior case space through natural flow, realize calm, without the humiture adjustment of overshoot.

Component label declaration among the figure:

1 outer container, 2 interior casees, 3 Venetian blinds, 4 Venetian blinds control motor, 5 temperature control Air Blast fans, 6 cold/hot-air channels, 7 heating and cooling units, 8 auxiliary blower groups

Embodiment

The control of 1 outer container temperature:

Before the temperature adjustment, case 2 sidewall motors 4 cut out Venetian blind 3 in system's control, then incubator starts Air Blast fan 5 on outer container 1 rear wall and sends into cold/hot blast and air is stirred reach requirement temperature (because interior case is at this moment as totally-enclosed, can to install small-sized fans 8 additional between interlayer some for the enhancing air cycle efficiency) in the forced convection mode.

2 interior case temperature controls:

After temperature reaches condition between interlayer, system closing Air Blast fan 5 and all auxiliary blowers 8, temperature is up to standard and evenly calm between interlayer at this moment, then case 2 Venetian blinds 3 in system opens, allow air up to standard between interlayer exchange to the mycotic culture space of interior case, to greatest extent Reality simulation mould-growth condition through natural convection.

Claims

1. inside and outside jacket structure, skin is done heat insulation processing, and interior layer box body loads test specimen.

2. the internal layer sidewall plate adopts louver structure, manually or electronic controls simultaneously every leaf angle of release, realizes that switch is controlled, and can reach adjustment to rate of heat exchange by the control of angle of release angle.

3. the same side wallboard can adopt the amalgamation of blinds block, and each block Venetian blind can be controlled respectively also can realize a plurality of Venetian blind interlocks by the controller programming, and different as requested, angle of release can be different.

4. be not limited only to two sidewalls of proofing box, depending on the test actual conditions, this type of automatically controlled louver structure all can be adopted in each surface of internal box wall.

5. the expanded application of louver structure theory:

Be not limited only to the luffing angle adjustment of blinds, also have two fans or fan Venetian blind more overlapping and realize covering the face switch by the push-and-pull translation.

6. after blinds was closed, interior case complete closed can install fan additional and strengthen convection current in the interlayer air channel.
