Detailed description of the invention
Refrigerator (1) comprising: fresh food compartment (2), wherein places article to be cooled; And at least one defrosting room (4) be arranged within fresh food compartment (2), it has makes inside by least one heater element (3) heated, and wherein places freezing article (Fig. 1, Fig. 2).
Refrigerator of the present invention (1) also comprises: first sensor (5), detects defrosting room (4) inner temperature when it is in freezing article are placed into defrosting room (4); And control unit (6), it is according to the temperature value (T detected by first sensor (5) 1) calculate the first rate temperature change (dT 1/ dt 1), its first rate temperature change (dT that will calculate 1/ dt 1) with by the limiting temperature rate of change (dT/dt) of the pre-recorded determination in its memory of the producer limitcompare, if the first rate temperature change (dT calculated 1/ dt 1) be greater than limiting temperature rate of change (dT/dt) limit, then course of defrosting is started by starting heater element (3) and freezing article is thawed.The temperature of defrosting room (4) no better than the temperature of fresh food compartment (2) because defrosting room (4) is arranged within fresh food compartment (2).When freezing article are placed in defrosting room (4), the internal temperature of defrosting room (4) changes due to the temperature difference between freezing article and defrosting room (4).If the first rate temperature change (dT calculated by control unit (6) 1/ dt 1) be greater than by the limiting temperature rate of change (dT/dt) of the pre-recorded determination in its memory of the producer limit, then heater element (3) is started by control unit (6).By providing the heating of the inside of defrosting room (4), course of defrosting is started.Therefore, the process of the article be placed in defrosting room (4) that thaw by control unit (6) automatically, and get involved (Fig. 3) without the need to user.
In an embodiment of the present invention, refrigerator (1) comprises resistance-type heater part (3).The operation of heater element (3) is adjusted by control unit (6).By being arranged in the heater element (3) in defrosting room (4), freezing article are thawed effectively.
In an embodiment of the present invention, refrigerator (1) comprises defrosting room (4), it has by the base portion of the manufacture of materials with high heat conductivity (8) and the heater element (3) that is arranged in the lower surface of base portion (8), and first sensor (5), it detects the temperature of base portion (8).When freezing article are placed on base portion (8), due to the low temperature of freezing article, the temperature of base portion (8) declines.When freezing article are placed in defrosting room (4), according to the temperature value (T detected within certain time interval by first sensor (5) 1) the first rate temperature change (dT of determining 1/ dt 1) be greater than limiting temperature rate of change (dT/dt) limitwhen, control unit (6) starts heater element (3) by making the inside of defrosting room (4) be started by the process heating the freezing food that makes to thaw.By being arranged in the first sensor (5) that base portion (8) is upper and be arranged on the surface identical with freezing article, first sensor (5) is provided as accurately detecting and above causes the temperature occurred on base portion (8) to reduce (Fig. 3) owing to freezing article to be placed on base portion (8).
In an embodiment of the present invention, refrigerator (1) comprising: at least one fan (10) that air is wherein pushed; And at least one second sensor (7), it detects the inner temperature of defrosting room (4) during course of defrosting; And control unit (6), it is by by by the predetermined record of producer lower-limit temperature value (T in its memory lower) and ceiling temperature value (T upper) with the temperature value (T to be detected by the second sensor (7) 2) compare, carry out the operation of control heater part (3) and fan (10) during course of defrosting.The internal temperature of the defrosting room (4) raised by heater element (3) is detected by the second sensor (7).As the temperature value (T detected by the second sensor (7) 2) equal ceiling temperature value (T upper) time, heater element (3) is stopped by control unit (6), and fan (10) continues to run.The cold air diffused out from the freezing article defrosting room (4) is provided as by fan (10) Inner eycle in defrosting room (4), and therefore the temperature of base portion (8) reduces.As the temperature value (T detected by the second sensor (7) 2) equal lower-limit temperature value (T lower) time, heater element (3) is started by control unit (6), again to run.Therefore, freezing article are provided as being thawed in the best condition (Fig. 2).
In an embodiment of the present invention, control unit (6) is according to the temperature value (T detected by the second sensor (7) 2) calculate the second rate temperature change (dT 2/ dt 2), and according to the second rate temperature change (dT calculated 2/ dt 2) carry out the operation of control heater part (3) and fan (10).If the second rate temperature change (dT determined by control unit (6) 2/ dt 2) higher than limiting temperature rate of change (dT/dt) limit, then fan (10) continues to run, and heater element (3) stops.Therefore, freezing article are provided as being undergone no deterioration by thawing at optimum conditions.
In an embodiment of the present invention, if the second rate temperature change (dT 2/ dt 2) be less than by the limiting temperature rate of change (dT/dt) of the pre-recorded determination in its memory of the producer limit, then control unit (6) makes the end of run of heater element (3) and fan (10).Therefore, the process of the freezing article be placed in defrosting room (4) that thaw is terminated by control unit (6), and gets involved without the need to user.
In an embodiment of the present invention, refrigerator (1) comprises the thermal insulation element (9) being arranged in heater element (3) below.Therefore, prevent the inside of fresh food compartment (2) from being heated due to the heat given off at the run duration of heater element (3).In addition, by preventing the heat given off from heater element (3) from leaving defrosting room (4), energy loss (Fig. 3) is prevented.
In an embodiment of the present invention, first sensor (5) is arranged on the upper surface of base portion (8).Therefore prevent first sensor (5) to be subject to the impact of heat when heater element (3) runs, and control unit (6) is provided as the first rate temperature change (dT accurately determining freezing article 1/ dt 1).
In an embodiment of the present invention, base portion (8) is produced by metal material.The thermal sensitivity of this metal material is very high.Therefore, by detecting the temperature of freezing article, preventing and starting the loss of time in course of defrosting.
In an embodiment of the present invention, refrigerator (1) comprises at least one siren (11), and it can notify user when course of defrosting starts.By by siren (11) sends audible signal or visual signal notifies user's course of defrosting.
In an embodiment of the present invention, refrigerator (1) comprises at least one siren (11), and it can notify user at the end of course of defrosting.When course of defrosting completes, the operation of heater element (3) is stopped by control unit (6).Meanwhile, by sending audible signal by siren (11) or visual signal notifies user (Fig. 1).
By present invention achieves a kind of refrigerator (1), it has defrosting room (4), the first rate temperature change (dT wherein in defrosting room (4) 1/ dt 1) detected, and when during freezing article are placed into defrosting room (4), course of defrosting automatically starts and gets involved without the need to user.
Will be appreciated that and the invention is not restricted to above disclosed embodiment, and those of skill in the art can easily introduce different embodiments.These different embodiments also should be taken into account in the scope of claim of the present invention.
