Fig. 2 is the temperature-changing chamber temperature-controlled process flow chart that the preferred embodiment of the present invention one provides.
In figure, be labeled as:
1, casing; 2; Temperature-changing chamber; 11, display screen; 12, regulate button.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
Preferred embodiment one:
This preferred embodiment provides a kind of refrigerator with temperature-changing chamber.As shown in Figure 1, this refrigerator comprises casing 1, is arranged on the control device at casing 1 back and is arranged on the independently temperature-changing chamber 2 in casing 1.Temperature in temperature-changing chamber 2 is set by control device, and the Temperature Setting scope in temperature-changing chamber 2 is in (18 ℃, 10 ℃).Preferably, by the Temperature Setting in temperature-changing chamber 2, be (7 ℃, 0 ℃), form soft freezing region.
In soft freezing region, store the foods such as cube meat, food is in supercooling frozen state.Can extend fresh keeping time, again can be like a cork by required shapes such as cube meat dicing, silks.This conclusion has obtained the evidence of great many of experiments.
Temperature-changing chamber 2 is positioned at the below of refrigerating chamber, the top of refrigerating chamber, separated with refrigerating chamber with refrigerating chamber respectively by thermal-insulation baffle plate; The back side of temperature-changing chamber 2 is also thermal-insulation baffle plate, guarantees that temperature-changing chamber 2 maintains soft freezing state.
In temperature-changing chamber 2, be provided with independently air inlet and return air inlet.Cold air enters temperature-changing chamber 2 by air inlet, to temperature-changing chamber 2 coolings.The evaporator fin of cold air circulation device of refrigerator adopts copper product to make.Copper material has antibacterial function, guarantees that purification, the food of temperature-changing chamber 2 inner airs is not subject to microbial contamination.
In temperature-changing chamber 2, be provided with temperature measuring equipment, the temperature value that control device can record according to temperature measuring equipment is controlled the unlatching of temperature-changing chamber 2 air inlets and/or is closed.Preferably, temperature measuring equipment is infrared sensor, and infrared sensor can be sent to control device by the temperature value by reserve surface detecting.According to determined whether to continue to be blown into cold air by the temperature value on reserve surface, soft refrigerating effect is better.
In temperature-changing chamber 2, be provided with at least one plug-type drawer, drawer bottom is provided with pulley.In temperature-changing chamber 2, be provided with position sensor, this position sensor can send cue to control device after drawer being detected and being drawn out of-pushing back.
In order to use more easily, in refrigerator doors arranged outside display unit, display unit comprises display screen 11 and regulates button 12.By display screen 11 and adjusting button 12, can show current temperature value, set the temperature required value of user, select other functions such as degerming, divide warm area, Tong Suo etc.
As shown in Figure 2, the temperature-changing chamber temperature-controlled process of this refrigerator comprises the steps:
Step 1: set the temperature range value (7 ℃, 0 ℃) of temperature-changing chamber 2 according to user's request, temperature-changing chamber 2 forms soft freezing region.
Step 2: control device is opened the air door of air inlet.
Step 3: send cold wind in temperature-changing chamber 2, the interior beginning of temperature-changing chamber 2 lowered the temperature.
Step 4: temperature measuring equipment detected temperatures value, when temperature value goes to step 5 when (7 ℃, 0 ℃) are interior; Otherwise go to step 3; Preferably, temperature measuring equipment is infrared sensor, and institute's detected temperatures value is by the temperature value on reserve surface.
Step 5: control device cuts out the air door of temperature-changing chamber 2 air inlets.Stop sending into after cold wind, the temperature of temperature-changing chamber 2 will no longer reduce.
Step 6: timer zero clearing, starts timing.Setting-up time S1 is 3 minutes.
Step 7: temperature measuring equipment detected temperatures value after timing reaches setting-up time S1, measured temperature value goes to step 6 when (7 ℃, 0 ℃) are interior; Otherwise go to step 2.
In said process, when control device receives after the cue that position sensor sends, program goes to step 4 from current step at once.This cue represents that drawer is drawn out of-pushes back, and the temperature in this process in drawer very easily raises.Especially when indoor temperature is higher or when user opens wide drawer overlong time, the temperature in drawer raises obviously.After drawer is pushed back, which step that control device is currently operating at program all must go to step 4 at once, determine whether the temperature in drawer the exceeds scope of (7 ℃, 0 ℃), and carry out corresponding step according to temperature-measuring results.
