As depicted in figs. 1 and 2, refrigerating space 1, temperature-changing chamber 2, refrigerating drawer 3, air channel 4, refrigeration blower fan 5, refrigeration evaporator 6, refrigeration heater strip 7, air door 8, alternating temperature air channel 9.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
As shown in Figure 1, a kind of temperature-changing chamber of the present invention has the control method of defrosting function refrigerator, is arranged on the wind cooling refrigerator in refrigerating chamber for temperature-changing chamber.
The refrigerating chamber of refrigerator divides three parts, the refrigerating space 1 that top is large space, and centre is temperature-changing chamber 2, bottom is refrigerating drawer 3.Be provided with air channel 4 at the back of refrigerating chamber, interior refrigeration blower fan 5 and the refrigeration evaporator 6 of arranging in air channel 4, the bottom of refrigeration evaporator 6 is provided with refrigeration heater strip 7, be provided with an air door 8 in the centre position in air channel 4, air door 8 is separated the refrigerating space on top 1 and temperature-changing chamber 2 and refrigerating drawer 3, refrigeration blower fan 5, refrigeration evaporator 6 and refrigeration heater strip 7 are arranged on the back of temperature-changing chamber 2 and refrigerating drawer 3, above temperature-changing chamber 2, be communicated with an alternating temperature air channel 9, alternating temperature air channel 9 is for sending separately cold air to temperature-changing chamber 2.
Temperature-changing chamber 2 have soft freezing, fresh-keeping, refrigerate, thaw, iced five functions, correspondence arranges five function buttons, wherein, soft freezing design temperature is generally 0-7 DEG C, fresh-keeping design temperature is generally-1 DEG C, and the design temperature thawing is 5-8 DEG C, and user selects corresponding function button as required, temperature-changing chamber 2 just can be changed between each function, as being used as common refrigerating chamber, soft freezing chamber, fresh-keeping chamber, defrosting room or iced chamber.
As shown in Figure 2, describe the control method of thawing below in detail, specifically comprise the steps:
1, user regulates the start gear of refrigerating chamber as required, gear difference, and the turn-on temperature of refrigerating chamber is also different, and in the present embodiment, the design temperature of start is set between 2-8 DEG C.
User presses the function button thawing as required, and temperature-changing chamber 2 does defrosting room use, and the design temperature of defrosting room is at 5-8 DEG C.In the present embodiment, the time of thawing is made as 4h, 6h, 8h, tetra-gears of 10h, in order to the food of the Different Weight of thawing.
2, when temperature of refrigerating chamber reaches the design temperature of start, compressor and refrigeration blower fan 5 start, and air door 8 is opened, and starts refrigeration.
Return air in refrigerating chamber enters air channel 4 through the return air inlet being arranged on wall of inner container, carry out heat exchange with refrigeration evaporator 6, cold air after cooling enters respectively refrigerating space 1, temperature-changing chamber 2 and refrigerating drawer 3 along air channel 4 and alternating temperature air channel 9 under the effect of refrigeration blower fan 5, and refrigerating chamber is lowered the temperature.
In this process, control compressor and at full throttle turn round, make refrigerating chamber within the shortest time, reach fast design temperature, give the reserved more time of heating of temperature-changing chamber 2.
3, reach after the design temperature of refrigerating chamber until refrigeration, control compressor and refrigerate blower fan 5 and shut down, start temperature-changing chamber 2 and heat.
Now, connecting refrigeration heater strip 7, close air door 8, start refrigeration blower fan 5, utilize alternating temperature air channel 9 to supply hot gas to temperature-changing chamber 2, is the food defrosting in temperature-changing chamber 2, until reach the design temperature that thaws and the thawing time of setting.
In the time that refrigeration finishes; can not start immediately refrigeration heater strip 7, need machine to be compressed to stop after certain hour t1, restart and connect refrigeration heater strip 7; in the present embodiment; time t1 is chosen as 5 minutes, and machine to be compressed is shut down and after at least 5 minutes, restarted refrigeration heater strip 7, because while just having shut down; the temperature of refrigeration evaporator 6 is very low; first allow the temperature of refrigeration evaporator 6 naturally go up a period of time, then open refrigeration heater strip 7, can reach energy-conservation effect.
4, refrigeration heater strip 7 is in heating process; detect the temperature of refrigeration evaporator 6 by refrigeration defrosting sensor; in the time detecting that the temperature of refrigeration evaporator 6 reaches protection temperature (in the present embodiment, this protection temperature is made as 16 DEG C, the highest can be set as 40 DEG C), finish to thaw heating schedule; disconnect refrigeration heater strip 7; close refrigeration blower fan 5, stop supplying hot gas to temperature-changing chamber 2, avoid refrigerating 7 working times of heater strip long; the excess Temperature of refrigeration evaporator 6, plays the effect of protection.
In the time that refrigeration heating schedule finishes, can not start immediately compressor cooling even if meet the entry condition of refrigeration, need to stop heating after certain hour t2, restart compressor, in the present embodiment, time t2 is chosen as 10 minutes, restart compressor cooling wait refrigerating after heater strip 7 stops heating at least 10 minutes, because while just stopping heating, the temperature of refrigeration heater strip 7 is higher, first allow the temperature of refrigeration heater strip 7 naturally fall after rise a period of time, then open compressor cooling, can reach equally energy-conservation effect.
Thawing of temperature-changing chamber 2 hockets with the refrigeration of refrigerating chamber, in the time that the temperature in refrigerating chamber reaches the design temperature of start, stops the heating schedule that thaws, restart refrigeration program, for refrigerating chamber cooling, in the time that refrigerating chamber reaches design temperature, stop refrigeration, again enter the heating schedule that thaws.
Thaw is that food is thawed to soft freezing state from freezing state, after the thawing time of setting has arrived, temperature-changing chamber 2 returns to soft freezing procedure operation automatically, ensures not have after thawing the food of taking-up in time in being easy to the state of cutting, can avoid again food spoilage simultaneously.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
