Describe refrigerator in detail with reference to accompanying drawing below according to the utility model.
Shown in Fig. 1-2, the refrigerator according to the utility model comprises: casing 10, door body (not shown), heater 30, evaporimeter 40, temperature sensor (not shown) and temperature controller 60.
Specifically, be formed with sour milk chamber 101 in the casing 10.
Said door body is pivotably mounted on the casing 10 to open and close sour milk chamber 101.
Heater 30 is used for sour milk chamber 101 is heated.
Evaporimeter 40 is used for being freezed in sour milk chamber 101.
Said temperature sensor is used to detect the temperature in the sour milk chamber 101.
Temperature controller 60 links to each other so that control heater 30 is heated to first predetermined temperature with sour milk chamber 101 and keeps stopping heater 30 after said first preset temperature for preset time with heater 30, evaporimeter 40 and said temperature sensor, controls evaporimeter 40 then and is freezed to second predetermined temperature in sour milk chamber 101.
Refrigerator according to the utility model; When the user prepares sour milk; After being heated to first predetermined temperature with sour milk chamber 101 and keeping said first preset temperature for preset time, temperature controller control heater 30 stops 101 heating of 30 pairs of sour milk chambers of heater; So that sour milk fully fermentation under suitable adjustment is controlled evaporimeter 40 then and is freezed to second predetermined temperature in sour milk chamber 101, so that sour milk is carried out stored refrigerated.Thus, can accurately control the fermentation temperature and the fermentation time of sour milk, and after yogurt production is accomplished, can carry out stored refrigerated sour milk, convenient and practical.
According to an embodiment of the utility model, said refrigerator also comprises the timer (not shown).Temperature controller 60 links to each other with said timer, and the said timer of temperature controller 60 controls picks up counting when detecting said first predetermined temperature at said temperature sensor.Thus, can further accurately control the fermentation time in the preparation sour milk process.
According to some embodiment of the utility model, as shown in Figure 2, heater 30 is located in the sour milk chamber 101.Thus, can improve the efficiency of heating surface, reduce the use cost of refrigerator to save the energy.
Need to prove that at this sour milk chamber 101 is chambers between an independence of refrigerator, its periphery is wrapped in foam insulation; Heat-proof quality is good, therefore, and when sour milk chamber 101 is heated; Not can and other chambers of refrigerator carry out heat exchange, do not influence the normal function of other chambers of refrigerator.This is understandable for the person of ordinary skill of the art, repeats no more at this.
According to an example of the utility model, evaporimeter 40 is located in the sour milk chamber 101, with the evaporimeter as 101 special uses of sour milk chamber.It is understandable that when the user did not need the ice making sour milk, heater 30 was not worked, sour milk chamber 101 can be used as common chamber of refrigerator, for example can be used as refrigerating chamber, refrigerating chamber or temperature-changing chamber and uses.Thus, can improve the space availability ratio of refrigerator.
According to a concrete example of the utility model, said first predetermined temperature is 40 ℃-43 ℃.Under this temperature conditions, the growth of lactic acid bacteria optimum, therefore best for the ferment effect of sour milk, can make the best sour milk of local flavor.
According to some examples of the utility model, the said scheduled time is 3-5 hour.Can guarantee the quality of sour milk thus, avoid fermentation time long and make sour milk rotten, influence quoting of user.
According to an embodiment of the utility model, said second predetermined temperature is 4 ℃.Thus, after yogurt production was accomplished, said refrigerator can carry out stored refrigerated to sour milk, to keep the local flavor and the nutrition of sour milk.
According to some embodiment of the utility model, heater 30 comprises sheet metal and is installed in the heating on the said sheet metal.Advantageously, said sheet metal can be selected from any in aluminium flake, iron plate or the copper sheet, or is processed by alloy material.Advantageously, said heating can be heating wire, or processes heating by the PTC ceramic material.Thus, can be so that heat 30 pairs of sour milk chambers 101 of heater, and heats is good, cuts down the consumption of energy.
Below simple the description adopt the refrigerator of implementing according to the utility model to carry out the process of yogurt production.
The user is added in an amount of plain chocolate and a small amount of sour milk or commercially available active lactic acid bacteria powder such as in the preparation containers such as stainless steel cup according to preset blending ratio, puts into sour milk chamber 101 after stirring.30 pairs of sour milk chambers 101 of temperature controller 60 control heaters heat and the temperature maintenance that makes sour milk chamber 101 at 40 ℃ of-43 ℃ of these temperature thresholds.The user can be according to the plain chocolate amount and the fermented bacterium amount that add, and selectivity kept this temperature threshold 3-5 hour.After fermentation was accomplished, temperature controller 60 control heaters 30 quit work, and made 40 pairs of sour milk chambers of evaporimeter, 101 refrigeration so that sour milk chamber 101 changes frozen state (being that temperature remains on about 4 ℃) over to.At this moment, the activity of lactic acid bacteria is inhibited, and fermentation stops, and the local flavor and the nutrition of sour milk are in optimum state.And under this frozen state, sour milk can be preserved 2-4 days, and is convenient and practical.
According to the refrigerator of the utility model embodiment, can accurately control fermentation temperature and fermentation time, and after yogurt production is accomplished, can carry out stored refrigerated sour milk, convenient and practical.
