Abstract

The utility model discloses an electro-thermal constant-temperature culture box for culturing mushroom. An inner chamber bottom and two side surfaces of a box (1) connected with an electro-thermal body (4) are provided with heat conduction channels (2) which are composed of insulation boards (5) and baffle boards (3) at intervals; the surfaces of the baffle boards (3) are arranged with a plurality of heat conduction holes (6). The heat radiation high-temperature air produced by electro-thermal body passes heat conduction channels along the bottom of the box to carry out convective conduction with the two sides of the heat conduction channels, and passes the heat conduction holes on the surfaces of the baffle boards to carry out heat conduction from lower inner chamber to upper inner chamber, and the heating temperature of the inner chamber of the box conducts evenly and reaches the thermal balance temperature value fast because of heat accumulation and heat emission of the insulation boards and the baffle boards. By experimenting, the temperature difference value between the upper inner chamber of the box and the lower inner chamber of the box is less than 1Deg.C. Compared with the prior art, the thermal balance temperature difference value of the utility model is less than that of the water-resistant culture box, and the production and use costs of the utility model are 1/3 time than the costs of the water-resistant culture box.

Description

Electro-heating standing-temperature cultivator

(1) technical field: the utility model relates to electric heating temperature control equipment; Be specifically related to a kind of electro-heating standing-temperature cultivator.

(2) background technology: electric heating incubator of the prior art is that hospital, food processing enterprises or Bioexperiment unit are used to the specific equipment cultivating mushroom or cultivate fine seed strains.Its structure is to be connected with electric heating element in its cabinets cavity bottom, when need carry out physico-chemical analysis to mushroom, the vessel that the experimenter will fill mushroom usually are placed on the shelf of incubator intracoelomic cavity, and control electric heating element heat temperature raising carries out the mushroom cultivation to certain temperature value.It exists deficiency to be: the thermal radiation that the electric heating element heat temperature raising of cabinets cavity bottom produces directly upwards conduction fill on the container of mushroom at shelf, and the temperature of the temperature of cabinets cavity upper space and lower space produces bigger temperature approach.Usually electrically heated is after 30 minutes, and its upper and lower spatial temperature approach has seriously influenced the physico-chemical analysis that operator cultivate mushroom about 15 ℃.Enterprise can only choose the less water isolation type incubator of thermal equilibrium temperature approach usually, and its complex structure, the higher production use cost that has increased enterprise significantly of price.

(3) summary of the invention: at the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of heat temperature raising temperature approach little, and the low electro-heating standing-temperature cultivator of production use cost.

For achieving the above object, the technical solution of the utility model is to realize like this, this electro-heating standing-temperature cultivator, comprise casing and be connected in the electric heating element of its intracavity bottom, its improvement is: on the described cabinets cavity bottom and its both side surface that is connected with electric heating element, be spacing respectively and be provided with the heat conduction runner that is joined and constituted by thermal baffle and dividing plate; On the surface of described dividing plate, be respectively equipped with a plurality of thermal holes.

The utility model is taked said structure, thermal radiation high temperature air when the generation of electric heating element heat temperature raising, conduct to its both sides heat conduction runner convection current along bottom half by the heat conduction runner, and a plurality of thermal holes that are provided with by baffle surface, the cavity space from top to down carries out the heat conduction within it, and the accumulation of heat of thermal baffle and dividing plate, heat radiation, the Heating temperature conduction that makes cabinets cavity is evenly and reach the thermal equilibrium temperature value soon.Through testing: electrically heated 15 minutes, the upper and lower spatial temperature approach of its cabinets cavity is less than 1 ℃.Compare with prior art: its thermal equilibrium temperature approach is less than the temperature approach of water isolation type incubator; The production use cost only be its about 1/3.

(4) description of drawings: Fig. 1 has the synoptic diagram of local section for the utility model;

Fig. 2 is the left view of Fig. 1.

(5) embodiment: Fig. 1-shown in Figure 2.This electro-heating standing-temperature cultivator comprises casing 1 and is connected in the electric heating element 4 of its intracavity bottom.On the described cabinets cavity bottom and its both side surface that is connected with electric heating element 4, be spacing respectively and be fixed with heat insulation felt plate 5 and iron dividing plate 3, and dock mutually by it and to have constituted heat conduction runner 2; On the surface of described dividing plate 3, be respectively equipped with 7 rows, every row is 5 thermal holes 6.The described dividing plate 3 that is connected in cabinets cavity is spacing with the cabinets cavity top and leaves runner mouth (shown in Figure 1).Described electric heating element 4 is nichrome wire.Can certainly be one of them of electrothermal tube or hot plate.The container of during use splendid attire being cultivated mushroom places on the shelf 7, close cabinet door, control nichrome wire heat temperature raising is to the certain temperature value, cabinets cavity up and down spatial thermal radiation temperature can conduct by constantly circulate exchange, convection current of high temperature air, has reached thermally equilibrated temperature constant state soon.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characterictic that the process creative work just can be associated; can also make some modification or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.

Claims (3)

1, a kind of electro-heating standing-temperature cultivator comprises casing (1) and is connected in the electric heating element (4) of its intracavity bottom; It is characterized in that: on described casing (1) intracavity bottom and its both side surface that is connected with electric heating element (4), be spacing respectively and be provided with by the join heat conduction runner (2) of formation of thermal baffle (5) and dividing plate (3); On the surface of described dividing plate (3), be respectively equipped with a plurality of thermal holes (6).
