The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1, the refrigerator low temperature compensating method with temperature-changing chamber of the present invention, 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 operated by rotary motion have soft freezing, fresh-keeping gear, refrigeration gear etc., the design temperature of soft freezing gear is generally-7 ℃, the design temperature of fresh-keeping gear is generally-1 ℃, and in the time that user is adjusted to this two gears, temperature-changing chamber 2 is just as soft freezing chamber or fresh-keeping chamber.
Low temp compensating of the present invention refers in the time that temperature-changing chamber is set in soft freezing gear (7 ℃) or fresh-keeping gear (1 ℃), because temperature is lower than refrigerated storage temperature, the temperature that makes refrigerating drawer 3 is influenced and lower than zero degree, the food of refrigerating drawer 3 can be frozen, and avoid the temperature of refrigerating drawer 3 lower than zero degree by the mode of low temp compensating of the present invention.And do not selecting soft freezing gear or fresh-keeping gear; while only selecting refrigeration gear, do not carry out following low temp compensating, reach and keep the state of shutting down after design temperature; until the temperature in temperature-changing chamber 2 rises to turn-on temperature again, then restart compressor and enter refrigerating state.
As shown in Figure 2, describe the method for low temp compensating 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, turn-on temperature is set between 2-8 ℃.User is set in soft freezing gear or fresh-keeping gear more as required, and the design temperature of soft freezing gear is-7 ℃, and the design temperature of fresh-keeping gear is generally-1 ℃.
2, when temperature of refrigerating chamber reaches turn-on temperature, 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 return air inlet, carries out heat exchange with refrigeration evaporator 6, and the 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.
3, reach after the design temperature of temperature of refrigerating chamber and temperature-changing chamber until refrigeration, compressor and refrigeration blower fan 5 are shut down, and now, testing environment temperature, if environment temperature during lower than design temperature T1, starts refrigeration heating.
In the present embodiment, the design temperature T1 that starts refrigeration heating is 22 ℃, only has when environment temperature is during lower than 22 ℃, just starts refrigeration and heats.
4,, while starting refrigeration heating, compressor shutdown, connects refrigeration heater strip 7, opens air door 8, starts refrigeration blower fan 5, supplies hot gas, so that the temperature of refrigerating space 1, refrigerating drawer 3 is higher than 0 ℃ to refrigerating space 1, refrigerating drawer 3.
In the time that refrigeration finishes; can not start immediately refrigeration heating even if meet the entry condition of refrigeration heating, need machine to be compressed to stop after certain hour t2, restart and connect refrigeration heater strip 7; in the present embodiment; time t2 is chosen as 5 minutes, and machine to be compressed is shut down and after at least 5 minutes, restarted refrigeration heating, 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.
5, refrigeration heater strip 7 is in heating process, detect the temperature of refrigeration evaporator 6 by refrigeration defrosting sensor, when detecting that the temperature of refrigeration evaporator 6 reaches this ceiling temperature T2 in ceiling temperature T2(the present embodiment and is made as 10 ℃) time, finish refrigeration heating schedule, disconnect refrigeration heater strip 7, close air door 8 and refrigeration blower fan 5, stop supplying hot gas to refrigerating space 1, refrigerating drawer 3.
The condition that finishes refrigeration heating schedule can also be, control the time of refrigeration heating, connecting the heat time when refrigeration heater strip 7 reaches this upper limit time t1 in upper limit time t1(the present embodiment and is set as 15 minutes) time, disconnect refrigeration heater strip 7, close air door 8 and refrigeration blower fan 5, stop supplying hot gas to refrigerating space 1, refrigerating drawer 3.
The condition that finishes refrigeration heating schedule can also be, detect the temperature of refrigeration evaporator 6 by refrigeration defrosting sensor, when reaching this lower limit temperature T3 in lower limit temperature T3(the present embodiment, the temperature of refrigeration evaporator 6 is made as 5 ℃), simultaneously, temperature of refrigerating chamber reaches turn-on temperature, or the temperature of temperature-changing chamber 2 reaches 0 ℃, disconnection refrigeration heater strip 7, close air door 8 and refrigeration blower fan 5, stop supplying hot gas to refrigerating space 1, refrigerating drawer 3.
While meeting above-mentioned one of them condition, the temperature of temperature-changing chamber 2 stops refrigerating heating schedule, because in starting low temp compensating, also can slowly be gone up, above-mentioned heating termination condition can guarantee that the temperature of temperature-changing chamber 2 can not exceed 0 ℃, all the time in design temperature control range.
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 t3, restart compressor, in the present embodiment, time t3 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.
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.
