Abstract
The utility model relates to a domestic constant-temperature fermentation cooker which is composed of a thermal insulation part and a temperature controlling part, wherein, a foaming thermal insulation layer is arranged between a plastic shell and a plastic inner pot of the thermal insulation part, and the temperature controlling part is composed of a temperature sensing circuit, a control circuit, a heating assembly, etc. Because the fermentation cooker and a cooker lid of the utility model are provided with a layer of foaming thermal insulation material, the temperature in the cooker can be maintained. Meanwhile, because a temperature control circuit is arranged in the cooker, when the temperature is lowered to a certain degree, the circuit can be operated, the heating assembly generates heat quantity, and the temperature in the cooker can be raised; when the temperature is raised to the certain degree, the power supply of the temperature control circuit is cut off automatically, and the heating assembly is cut off; therefore, the temperature constancy in the fermentation cooker can be ensured, and the fermenting success can be ensured.
Description
The utility model belongs to the article of human lives's needs, relates in particular to a kind of family expenses ferment at constant temperature pot.
At present, along with the raising of people's living standard, family usually does it yourself to leaven dough, a wine is made food, but from want of experience, seasonal variations often causing the fermentation failure, and the thermostatic equipment of industry, field of medicaments is not suitable for family in addition.
The purpose of this utility model is exactly in order to address the above problem, and guarantees under various ambient temperature conditions, can complete successfully domestic food sweats such as fermentation, a wine, and provide a kind of power consumption the low family expenses bacteria vat that also can keep constant temperature.
A kind of family expenses ferment at constant temperature pot partly is made up of insulating sections and temperature control, and it is characterized in that has one " foaming " heat-insulation layer between the pot in the plastic casing of insulating sections and the plastics, and one " foaming " heat-insulation layer is also arranged in the pot cover; The temperature control part is made up of current rectifying and wave filtering circuit, temperature sensing circuit, control circuit, main switch circuit and heating component, current rectifying and wave filtering circuit links to each other with temperature sensing circuit, control circuit and main switch circuit respectively, and temperature sensing circuit, control circuit, main switch circuit and heating component link to each other successively.
Because the utility model bacteria vat and pot cover are equipped with one deck " foaming " insulation material, therefore, the temperature in the pot can keep.Simultaneously, also owing in the pot temperature-adjusting circuit being housed, when temperature is reduced to a certain degree, circuit working, heating component produces heat, and kettle temperature raises; When temperature rises to a certain degree, the temperature-adjusting circuit automatically cutting off power source, heating component quits work, thereby has guaranteed the temperature constant in the bacteria vat, guarantees to ferment successfully.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the block diagram of the utility model temperature control part;
Fig. 3 is the circuit diagram of the utility model temperature control part.
Describe in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the 1st, plastic casing, the 2nd, rigid foam heat-insulation layer, the 3rd, pot in the plastics, the 4th, plastic pot cover, the 5th, the rigid foam heat-insulation layer in the pot cover, the 6th, pot cover handle, the 7th, temperature control assembly.
As shown in Figure 2, the temperature control part is made up of current rectifying and wave filtering circuit, temperature sensing circuit, control circuit, main switch circuit and heating component, current rectifying and wave filtering circuit links to each other with temperature sensing circuit, control circuit and main switch circuit respectively, and temperature sensing circuit, control circuit, main switch circuit and heating component link to each other successively.
