The specific embodiment
Carry out detailed explanation in the face of technical scheme of the present invention down.
The invention reside in provides a kind of flexible and changeable refrigerator to prevent condensation heating work mode; While can adopt this refrigerator to prevent effectively reducing in the condensation heating work mode process energy consumption of refrigerator, and this working method can effectively be avoided the influence to anti-condensation device use working life that the error burst of humidity sensor detection is brought in addition.
The present invention has additional humidity control module on the basis of the control device of original refrigerator; In this humidity control module, in advance humidity is divided into different humidity ranges; And the working method of the heater in advance that different humidity ranges is the corresponding simultaneously refrigerator also is stored in the above-mentioned humidity control module; Afterwards through being arranged on the humidity parameter of the humidity sensor measurement air on the refrigerator; And judge the humidity range in the humidity control module at this humidity parameter place, so just can come work according to the heating work mode of this corresponding humidity range correspondence.
Be exactly among the embodiment 1 whole humidity range is divided into 10 scopes with the mode of five equilibrium; Be about to whole humidity range and whenever divide a humidity range at a distance from 10% pair; Each humidity range of this division is defined as a humidity level G; And stipulated the working method of heater under the corresponding grades G, and the working method of the heater here just is meant the time ratio T of this heater start-stop, promptly this heater is opened and the ratio of dwell time; The initial value of regulation T is T0=1 in the present embodiment; And the start/stop time of a grade G of the above-mentioned division heater corresponding with it than T does, T=T0 * (1+G) just can obtain the time ratio T of start-stop of the heater of this humidity parameter correspondence like this when airborne humidity parameter that humidity sensor is surveyed and after confirming the residing humidity range of this humidity parameter.Be 34% to this humidity parameter for example in the humidity detection; The humidity range that then this humidity parameter is corresponding is 30%-40%; And corresponding humidity level is 40%, the start-stop of the heater that this humidity range is corresponding like this time ratio T=1 * (1+40%)=1.4, above-mentioned in other words heater is after having shut down 5 minutes; Need to start shooting 7 minutes to guarantee that refrigerator can not produce condensation under this humidity level; This is in order to guarantee that when surrounding air humidity is big more the relative time of heater start is just long more, could guarantee that like this refrigerator can not produce condensation.
Then be that whole humidity range is divided into 5 humidity ranges with the mode of five equilibrium among the embodiment 2; Promptly whenever dividing a humidity range at a distance from 20% divides; The corresponding humidity level G of each humidity range; Equally also stipulated the working method of heater under the corresponding humidity level, this working method also is meant the time ratio T of heater start-stop.In addition, in the present embodiment grade G and its time corresponding than the relational expression of T and the relational expression among the embodiment 1 too.Though the quantity of the humidity range of dividing among the embodiment 2 like this is less relatively; But can guarantee more effectively that in fact so but refrigerator can not produce condensation in each humidity range, because in the identical humidity range in embodiment 1, adopted the cause of the start-stop ratio of higher relatively heater.
Above all be that humidity range is divided with the mode of five equilibrium among two embodiment; And be as between the dividing regions of dividing humidity range with 10% and 20%; Need to prove also can adopt between the division methods that is different from the foregoing description and humidity province humidity range is divided, so just increased the flexibility that this humidity range is divided.The method that above-mentioned in addition humidity is divided might not be divided with the mode of five equilibrium; And still can humidity range be divided with the mode of non-five equilibrium or the mode of five equilibrium and the combination of non-five equilibrium; For example in the lower scope of humidity, adopt between the dividing regions of 20% division; And in the higher scope of humidity, adopt 10% as between the dividing regions of dividing humidity range, and can satisfy the needs of different operating positions so more, further increase application flexibility of the present invention.But preferably get between above-mentioned dividing regions and be not more than 20%; Otherwise this each humidity range will be excessive; Causing humidity sensor in excessive humidity range, all can control heater works under a fixing pattern; Not only cause the reduction of whole device accuracy, also caused the waste of the energy simultaneously.
Embodiment 3 is undertaken between adjacent humidity range, being provided with the buffering area in order to the humidity error that overcomes humidity sensor self perception after humidity range divided by the method among the embodiment 1.Here the humidity error of said humidity sensor is meant because humidity sensor self precision is inaccurate or the situation of the variation that ambient humidity does not just stop about on the line of demarcation that humidity range is divided; The variation that the anti-condensation heater working method that under above-mentioned situation, can cause is not stopped, thus have a strong impact on the heats of anti-condensation heater and the service life of control module.And after being provided with this buffering area, can effectively prevent the generation of above-mentioned situation.
In embodiments of the invention 1, in advance the humidity of environmental air is divided into 10 humidity ranges; Being exactly marginal both sides of adjacent humidity range on the basis of the foregoing description 1 among the embodiment 3 is provided with the humidity zone and forms buffering area; This buffering area five equilibrium is in adjacent humidity range; In the present embodiment, the buffering area at humidity range 30%-40% and 40%-50% is exactly to form by 37%-43%.
