Output port can be display screen, and output port is electrically connected with controller to show that the fortune of part 4 occurs in magnetic fieldRow state for example working time and remaining time etc.

In specific embodiments more of the present invention, as shown in Fig. 1-Fig. 6, refrigerator 100 also comprises having the anti-of magnetic conductivityGuard shield 5, protective cover 5 is located in degerming chamber 12 and outer covering on degerming case 3, and now, there is part 4 and be positioned at protection in magnetic fieldIn cover 5. Because protective cover 5 has magnetic conductivity, therefore protective cover 5 can form magnetic field and occur the screen in the magnetic field that produces of part 4Cover layer, to avoid magnetic field to leak, thereby avoid magnetic field to impact human body, also avoid magnetic field to refrigerator 100 weeks simultaneouslyThe interference of the electrical part enclosing. It should be noted that, the magnetic field shielding principle of protective cover 5 has been those of ordinary skill in the artInstitute is known, and is not described in detail here.

Particularly, as shown in Fig. 1-Fig. 6, protective cover 5 comprises cover body 51 and first body 52, and the front side of cover body 51 is spaciousOpen, first body 52 coordinates to open or close cover body 51 with cover body 51, and wherein, the opening 31 of degerming case 3 is located atOn the antetheca of degerming case 3.

Alternatively, as shown in Figure 3, the end face towards first body 52 of cover body 51 is formed as First terrace 303,The appropriate section of first body 52 is formed with second step face 521, and second step face 521 coordinates with First terrace 303,So that first body 52 can be sealed cover body 51 completely, thus the shielding action that improves protective cover 5.

More specifically, as shown in Figure 1 and Figure 4, first body 52 is located on the rear surface of degerming chamber door body 2, firstBody 52 is fixedly connected with degerming chamber door body 2, and degerming chamber door body 2 is connected through the hinge on cover body 51, thus, and when removingWhen bacterium chamber door body 2 is opened, first body 52 also opened thereupon, and in the time that degerming chamber door body 2 is closed, first body 52 alsoClose thereupon, thereby reduced the operating procedure that degerming case 3 uses.

Preferably, protective cover 5 is silicon steel part, thereby makes the permeability of protective cover 5 higher, and then makes protective cover 5Shield effectiveness to magnetic field is good. Certainly, protective cover 5 also can be other materials part, as long as protective cover 5 has certainPermeability, does not do concrete restriction here.

Further, refrigerator 100 also can comprise door switch (scheming not shown), and door switch is located on first body 52, doorThere is part 4 with magnetic field and be connected in switch, in the time that first body 52 opened cover body 51, door switch is closed magnetic field part 4 is occurred,In the time that first body 52 closed cover body 51, the operation of this Time Controller ability controlling magnetic field generation part 4. For example, Men KaiPass can be connected in series with coil 41, and in the time that first body 52 opened cover body 51, door switch disconnects so that coil 41 is carried outPower-off protection. Thus, there is the run duration of part 4 in magnetic field, in the time that user opens first body 52, door switchSetting can be closed immediately magnetic field and part 4 be occurred to avoid the injury of magnetic field to human body.

In specific embodiments more of the present invention, as Figure 1-Figure 5, coil 41 is wrapped in the perisporium of degerming case 3Upper, for convenience of description, the coil 41 that all claims in the following description the perisporium of this winding degerming case 3 is spiral coil.

Particularly, as Figure 1-Figure 5, in degerming case 3, limit the spatial accommodation 32 for holding food, degerming case3 antetheca opens wide the opening 31 that is communicated with spatial accommodation 32 to form. Spiral coil be wrapped on degerming case 3, form hollowSolenoid, now, spatial accommodation 32 is positioned at solenoidal inside.

In the example shown in Fig. 2-Fig. 5, degerming case 3 is formed as cuboid, on fore-and-aft direction, and spatial accommodation 32Connect degerming case 3. Protective cover 5 is also formed as cuboid housing substantially, and the rear end of degerming case 3 is fixed on cover body 51On.

With reference to Fig. 2, known according to common practise, the external magnetic-field direction of energization solenoid is from the solenoidal arctic (NThe utmost point) send and get back to the South Pole (the S utmost point), the magnetic direction of energization solenoid inside is (the S utmost point) from the solenoidal South PoleSend and get back to the arctic (the N utmost point). Now, solenoid internal magnetic field is even, and in one timing of solenoid energising electric current,Solenoid internal magnetic field intensity maximum. It should be noted that, the determination methods of the magnetic pole type at the two ends of energization solenoidFor common practise, be not described in detail here.

Thus, spiral coil can be at the interior formation high-intensity magnetic field of spatial accommodation 32 in when energising, thereby makes in spatial accommodation 32Food can under strong magnetic field action, realize sterilizing.

Now, because protective cover 5 has magnetic conductivity, the magnetic field of solenoid outside is extended along protective cover 5, and thenGet back to solenoid inside to form closed magnetic circuit. Thus, the setting of protective cover 5 can avoid magnetic field to leak.

In other specific embodiments of the present invention, as shown in Figure 6 and Figure 7, degerming case 3 is magnetic conductive part, coil 41Be wrapped on the sidewall relative with opening 31 of degerming case 3. For convenience of description, all claim in the following description this windingThe coil 41 of the sidewall relative with opening 31 of degerming case 3 is pole coil.

Particularly, as shown in Figure 6, degerming case 3 can be formed as " U " shape, and degerming case 3 comprises magnetic conduction arm 301 and twoIndividual support arm 302, pole coil is wrapped on magnetic conduction arm 301, and two support arms 302 are same from the two ends of magnetic conduction arm 301 respectivelyTo extension, magnetic conduction arm 301 and two support arms 302 form above-mentioned " U " shape. Here magnetic conduction arm 301 and two support arms,302 shape is not done concrete restriction, and for example, that magnetic conduction arm 301 can be formed as is plate shaped, cylindricality etc., and support arm 302 also canBe formed as plate shapedly or cylindrical, magnetic conduction arm 301 and support arm 302 also can form other shapes.

Between the inwall of magnetic conduction arm 301, two support arms 302 and degerming chamber door body 2, degerming case 3, limit for holding foodThe free end of 32, two support arms 302 of spatial accommodation and the inwall of degerming case 3 of product limit opening 31.

Here, degerming case 3 can have multiple placement form, for example, in the example depicted in fig. 6, two support arms 302Extend towards front from top and the bottom of magnetic conduction arm 301 respectively. Again for example, two support arms 302 also can be respectively from magnetic conductionLeft end and the right-hand member of arm 301 extend towards front. Again for example, two support arms 302 also can be respectively from two of magnetic conduction arm 301End extends upward, and now, the opening 31 of degerming case 3 upwards arranges.

With reference to Fig. 7, known according to common practise, the external magnetic-field direction of energising pole coil is the arctic from pole coil(the N utmost point) sends and gets back to the South Pole (the S utmost point), now, because degerming case 3 is magnetic conductive part, makes the pole coil of switching onExtend along degerming case 3 in the magnetic field producing, and that is to say, extend along magnetic conduction arm 301 and two support arms 302 in magnetic field, makesObtain two support arms 302 and be all with and be magnetic, and be respectively the South Pole (the S utmost point) and the arctic (the N utmost point). Now, with the N utmost pointSupport arm 302 on magnetic field extend towards the support arm 302 with the S utmost point, then along getting back to magnetic with the support arm 302 of the S utmost pointUtmost point coil inside is to form closed magnetic circuit. Thus, pole coil can be at the interior formation high-intensity magnetic field of spatial accommodation 32 in when energising,And Distribution of Magnetic Field is more even, thereby to the effective degerming of the food in spatial accommodation 32.

Preferably, magnetic conduction arm 301 and two support arms 302 are silicon steel sheet, thereby make the permeability of degerming case 3 higher,And then extend along degerming case 3 as much as possible in the magnetic field that pole coil is produced. Thus, can improve through spatial accommodation 32Magnetic field intensity, and improve magnetic field the energy utilization rate of part 4 occur. Certainly, magnetic conduction arm 301 and two support arms 302 are alsoCan be other materials part, as long as degerming chamber 12 has certain permeability, do not do concrete restriction here.

In the example depicted in fig. 6, in refrigerator 100, be provided with protective cover 5 to avoid leakage magnetic field, the interior table of degerming chamber 12Face is provided with magnetic conductive material layer 511, and magnetic conductive material layer 511 constructs cover body 51. Now, degerming case 3 respectively with cover body51, first body 52 interval arranges, thereby avoids magnetic field to extend and cause spatial accommodation 32 internal magnetic field intensity along protective cover 5Reduce, and then avoid magnetic field that the energy loss of part 4 occurs. Wherein, the free end of two support arms 302 and first body 52Between gap larger, to increase the magnetic resistance between support arm 302 and first body 52, thereby avoid magnetic field along first body 52Extend the magnetic field short circuit causing.

In some embodiments of the invention, not only can degerming in degerming chamber 12, can also freeze, and at direct cooling refrigeratorAnd all can be applied on wind cooling refrigerator. That is to say, degerming chamber 12 has formed the temperature-changing chamber of refrigerator 100, degerming chamber12 temperature can transform between room temperature and refrigerated storage temperature. Thus, the food in degerming chamber 12 can be at room temperature conditionLower degerming, the food after degerming can directly be stored in the degerming chamber 12 under refrigerating state, thereby raising refrigerator 100Space availability ratio.

In specific embodiments more of the present invention, as shown in Fig. 1-Fig. 4, Fig. 6 and Fig. 7, in degerming chamber 12, be provided withThe first evaporimeter 6 that compressor is connected, compressor provides cold to the first evaporimeter 6, that is to say degerming chamber 12Freeze by direct-cooled mode.
