Description

Semiconductor constant temp biochemical culture cabinet

The utility model relates to a kind of constant incubator, particularly the biochemical incubator of semiconductor thermostatic and temperature.

At present, biochemistry that bacterium training grows and so on will be carried out when cultivating in fields such as hospital, school, scientific research, foodstuffs industry, and the constant humidity equipment that generally uses is the electric hot water bath, and its constant temperature scope can only be at 30 ℃ with adjusted.If when needing the low temperature below 30 ℃, then all with machine-processed cool equipments of compression such as domestic refrigerators for it, owing to have machine operation mechanism and refrigeration agent, therefore noise is big, easy to wear, the life-span short, and environment is easily polluted, and refrigeration and pyrogenicity are irreversible, the big heaviness of body, inconvenience is carried.

The purpose of this utility model is exactly in order to address the above problem, and provides that a kind of refrigeration speed is fast, volume is little, noiseless, the biochemical incubator of cooling and heating type reversible semiconductor thermostatic and temperature.

Technical solution of the present utility model:

The biochemical incubator of a kind of semiconductor thermostatic and temperature, it includes inner bag 1, shell 2, top cover 3, the wet temperature controller J of number, semiconductor cooler G ₁, G ₂, be filled with lagging material 4, semiconductor cooler G in the interlayer between inner bag 1 and shell 2 and top cover 3 ₁, G ₂Be connected on the output terminal of voltage stabilized source IC, it is characterized in that the bottom appearance of inner bag 1 is provided with cold accumulator 5 and semiconductor cooler G ₁, be equipped with semiconductor refrigerator G in the wall appearance of inner bag 1 ₂, be positioned at inner bag 1 top cover 3 suitable for reading and also be provided with cold accumulator 5 and semiconductor cooler G ₂, the semiconductor cooler G of inner bag 1 bottom ₁Non-operative end be connected with scatterer 6, the semiconductor cooler G of inner bag 1 wall ₂Link to each other with shell 2 by thermal-arrest plate 7, dispel the heat, semiconductor cooler G in the top cover 3 to utilize shell 2 ₂The working end link to each other G with top cover 3 inwalls by cold accumulator 5 ₂Non-operative end also link to each other with top cover 3 outer walls by thermal-arrest plate 7, play thermolysis to utilize the top cover outer wall.

Temperature regulating range of the present utility model can be regulated between-10 ℃ to 70 ℃ continuously, precision can reach ± and 0.1 ℃, its refrigeration speed is fast, and volume is little, there is not mechanical works, noiseless, the life-span is long, and cooling and heating type is reversible, and can carry out vehicle-mounted long-distance transport in working order down, and the utility model is easy to manufacture, and the reliability height is easy to use.

Fig. 1 is a schematic surface of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is power supply reason figure of the present utility model.

As Fig. 1,10 connect as one by being hinged between shell 2 and the top cover 3, be provided with rubber weather strip 11 between them, number wet temperature controller J, power switch S are equipped with in the surface of shell 2 ₁, cooling-heating change-over switch S ₂With strong and weak switch S ₃Dismountable test-tube stand 8 and beaker carriage 9 are housed, to be used for placing test tube and apparatus such as beaker, flask (as Fig. 2) in inner bag 1.Principle of work of the present utility model such as Fig. 3 are as power switch S ₁During connection, AC power is added on the transformer T, is the wet temperature controller J power supply of number simultaneously, and the low-voltage AC of transformer T output is through bridge heap VD rectification, capacitor C ₁, C ₂Filtering and voltage stabilized source IC(model are 7812) voltage stabilizing obtains 12 volts of stable direct supplys.The output terminal of IC is by the contact J of the wet temperature controller J of number ₁, J ₂With cooling-heating change-over switch S ₂With semiconductor cooler G ₁Connect each semiconductor cooler G ₂By strong and weak switch S ₃Be attempted by G ₁Two ends.The direct supply one tunnel of IC output is supplied with electric fan M, and electric fan M is used for the scatterer 6 of inner bag 1 appearance bottom is carried out air blast cooling but, and another road of direct supply is through the contact J of the wet temperature controller J of number ₁, J ₂With cooling-heating change-over switch S ₂Be added to the semiconductor cooler G of inner bag 1 bottom ₁On, make the utility model pass through S ₂Finish cooling and heating type reversible function, if the quick cooling and heating type of palpus, the strong and weak switch S of then closing ₃Feasible each semiconductor cooler G that is contained in top cover 3 and inner bag 1 wall ₂Get electric work.The utility model is added with socket Z in the line, so that in transit, available vehicle-mounted 12 volts of direct supplys are sent into socket Z, guarantees that the utility model the temperature inside the box is constant in the way.
