Detailed description of the invention
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments are not limiting as the present invention, structure, method or conversion functionally that those of ordinary skill in the art is made according to these embodiments are all contained in protection scope of the present invention.
Refer to Fig. 1 to Fig. 4 and show a better embodiment of refrigerator 100 of the present invention.Refrigerator 100 of the present invention includes the casing 1 with refrigerator compartment 10, the door body (not shown) of switch refrigerator compartment 10, the door body switch detecting element 3 being arranged between casing 1 and door body, in order to opening part close in detecting refrigerator compartment 10 respectively and the first detector unit 4 and the second detector unit 5 of the temperature away from opening part, it is arranged on the described casing 1 two groups of air curtain generators 6 near the opposite side of refrigerator compartment 10 opening part, refrigeration system (not shown), and switch detecting element 3 with door body, first detector unit 4 is connected the control device 7 controlling air curtain generator 3 with the second detector unit 5.Described refrigeration system is also connected and the control of controlled device 7 with control device 7.
With reference to shown in Fig. 1, described casing 1 is provided with relative top side and bottom side and relative left side and right side；In the present embodiment, air curtain generator 6 described in two groups is oppositely arranged on left side and the right side of casing 1, thus the air-out distance needed for often organizing air curtain generator 6 can be made shorter, and then can ensure monsoon intensity, and energy consumption is relatively low；Certainly, also optional top side and the bottom side being oppositely arranged on casing 1 of air curtain generator 6 described in two groups, the most also purpose of attainable cost invention.
Described casing 1 includes the inner bag 11 being formed at around refrigerator compartment 10, shell (not shown) and the foaming layer (not shown) being arranged between inner bag 11 and shell (not shown).
Shown in Fig. 2 and Fig. 3, air curtain generator 6 described in each group include being arranged on refrigerator compartment 10 near the air port 61 of opening part, be arranged on the blower fan 62 outside air port 61 and house the housing 63 of blower fan 62.
In the present embodiment, described air port 61 is opened on the two side of described inner bag 11 and extends in refrigerator 100 short transverse.Described air port 61 connects described housing 63 and refrigerator compartment 10, so that the blower fan 62 in housing 63 can be dried in refrigerator compartment 10 from air port 61, thus forms air curtain.For making air curtain be covered with the front side of refrigerator compartment 10, the described air port 61 development length in refrigerator 100 short transverse is more than the 2/3 of the Sidewall Height of inner bag 11, and is positioned at the centre position of inner bag 11 sidewall in refrigerator 100 short transverse.
Described air curtain generator 6 includes multiple described blower fan 62 being uniformly arranged along refrigerator 100 short transverse, so that the wind of blower fan 62 blowout is uniformly covered with the front side of refrigerator compartment 10, thus forms preferable air curtain.The described housing 63 housing blower fan 62 is embedded in the foaming layer outside described inner bag 11, thus can be not take up the space outside the inner space of refrigerator compartment 10 or refrigerator 100 so that the overall visual effect of refrigerator 100 is preferable.
Certainly, described air curtain generator 6 entirety may also be arranged on inside inner bag 11 or is embedded on the sidewall of described inner bag 11.
In conjunction with shown in Fig. 1 to Fig. 4, described control device 7 mainly controls blower fan 62 forward or reverse in air curtain generator 6 according to the feedback information of door body switch detecting element the 3, first detector unit 4 and the second detector unit 5.
Structure in conjunction with the above refrigerator of the present invention 100 is arranged, and the invention still further relates to the control method of air curtain generator 6 in a kind of refrigerator 100, comprises the following steps:
Control device 7 and receive the switching information of the door body that door body switch detecting element 3 detects；
When detecting that door body is opened, the blower fan 62 that control device 7 controls in two groups of air curtain generators 6 rotates forward, and makes the relative air-out in two air ports 62, thus forms one air curtain in the front side of refrigerator compartment 10；
When detecting that door body is closed, control device 7 and obtain the first detector unit 4 and detection numerical value of the second detector unit 5, to obtain refrigerator compartment 10 near opening part with away from the temperature gap of opening part, and this temperature gap and a preset value are compared；In the present embodiment, this preset value is set to 1 DEG C；
If temperature gap is more than preset value, then the blower fan 62 controlled in two groups of air curtain generators 6 inverts, and makes cold air flow forward in refrigerator compartment 10, and control blower fan 62 stops operating after temperature gap no more than preset value.
When above-mentioned door body is closed, described control device 7 simultaneously detected value according to the temperature regime in refrigerator compartment 10, the i.e. second detector unit 5 controls the work of refrigeration system.
In sum, the present invention is respectively provided with one group of air curtain generator 6 by the opposite side of refrigerator compartment 10 opening part close on casing 1, thus bilateral flow air-out is formed when door body is opened, and then on front side of refrigerator compartment 10, form the preferable air curtain of intensity, effectively stop the entrance of refrigerator 100 outside air, inner side cold air to flow out；Additionally, when door body is closed, the present invention is close opening part and the temperature away from opening part in detecting refrigerator compartment 10 respectively also by the first detector unit 4 and the second detector unit 5, and the blower fan 62 controlling air curtain generator 6 when opening part temperature is higher inverts, thus draft when inverting by blower fan 62 causes the flow perturbation within refrigerator compartment 10, and then accelerate the relatively low cold air of the temperature inside refrigerator compartment 10 and mutually flow near the air that the temperature of opening is higher so that the temperature within refrigerator 100 reaches poised state.
It is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should be using description as an entirety, technical scheme in each embodiment can also form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the present invention; they also are not used to limit the scope of the invention, and all equivalent implementations or changes made without departing from skill of the present invention spirit should be included within the scope of the present invention.
