In some preferred embodiments, radio frequency generation module 190 can be configured to determine that defrosting is positioned in defrosting chamber 111 Pending thing optimal defrosting frequency, and produce frequency be optimal defrosting frequency radiofrequency signal.Radio-frequency antenna 130 is according to penetrating The radiofrequency signal that the raw module 190 that takes place frequently produces produces the rf wave of corresponding frequencies in defrosting chamber 111, and it is pending to thaw Thing.

Present inventor creatively has found, with the dielectric of the temperature change of pending thing, not only pending thing Coefficient can also change therewith, can also change suitable for the optimal defrosting frequency for the pending thing that thaws.The utility model passes through Determine the optimal defrosting frequency of the pending thing of defrosting, and make radio frequency that module 190 occur and produce frequency penetrating for optimal defrosting frequency Frequency signal improves defrosting efficiency, shortens thawing time come the pending thing that thaws, and then improves the facility of user's defrosting Property.

Radio frequency occurs module 190 and can be configured to according to default first time interval, incrementally to preset step-length from the every time One predeterminated frequency rises to the second predeterminated frequency, while calculates and record the corresponding rf wave absorptivity of each defrosting frequency.When When frequency increments to the second predeterminated frequency for the radiofrequency signal that module 190 produces occurs for radio frequency, the first predeterminated frequency is chosen to the The corresponding defrosting frequency of maximum radio frequency ripple absorptivity being calculated in two predeterminated frequencies is as optimal defrosting frequency, to being positioned over Pending thing in defrosting chamber 111 thaws.When maximum radio frequency ripple absorptivity corresponds to multiple (two or more) solutions When freezing frequency, the defrosting frequency of selecting frequency minimum is as optimal defrosting frequency, to reduce energy consumption.In this embodiment, first Time interval can be 1~3ms, such as 1ms, 2ms or 3ms.In some preferred embodiments, the mistake of optimal defrosting frequency is being determined Cheng Zhong, radio frequency occur module 190 and can be configured to after defrosting frequency first time interval is adjusted every time, calculated and record this The corresponding rf wave absorptivity of defrosting frequency, to prevent the time too short result being calculated inaccurate, overlong time is missed most Excellent defrosting frequency.Default step-length can be 0.5~2KHz, such as 0.5KHz, 1KHz, 1.5KHz or 2KHz, to improve optimal defrosting The accuracy of frequency.First predeterminated frequency can be 432.7~432.9MHz, such as 432.7MHz, 432.8MHz or 432.9MHz. Second predeterminated frequency can be 433.1~433.3MHz, such as 433.1MHz, 433.2MHz or 433.3MHz.It is preferred real at some Apply in example, the first predeterminated frequency can be 432.8MHz, and the second predeterminated frequency can be 433.2MHz.

Present inventor draws through many experiments, the frequency that the radiofrequency signal that module 190 produces occurs for radio frequency is existed One of 433MHz or so, which is adjusted in section, to change, and is not only remarkably improved defrosting efficiency, but also the juice loss of pending thing Rate is low, and penetration capacity is strong.Test indicate that the jelly ox for -18 DEG C of the 500g that thawed using the thawing apparatus 100 of the utility model Meat, makes its temperature rise to -3 DEG C, it is only necessary to and 12~15 minutes, and the inside and outside temperature difference of beef is less than 3 DEG C, has shorter solution Freeze time and higher temperature uniformity.

In a further preferred embodiment, radio frequency generation module 190 can be configured at interval of default second time Interval, carries out a secondary frequencies adjusting.It that is to say, module 190 occurs for radio frequency in the previous adjusting that adjacent twice frequency is adjusted, really The optimal defrosting frequency of the fixed pending thing being positioned in defrosting chamber 111 that thaws, and again with when secondary optimal defrosting frequency solution After freezing pending the second time interval of thing, secondary frequencies adjust and redefine defrosting and are positioned in defrosting chamber 111 after progress The optimal defrosting frequency of pending thing, and so on, solved with whole course of defrosting, targetedly treating processed material Freeze, improve the defrosting efficiency of pending thing.Second time interval can be 20~40 seconds, such as 30 seconds 20 seconds or 40 seconds, to prevent Only since the time interval between adjacent twice frequency is adjusted is too short, cause frequency to adjust too frequent, determine for rear time optimal Defrosting frequency is too small even without change with previous definite optimal defrosting frequency phase-difference, reduces defrosting efficiency on the contrary, makes solution Freeze effect to be deteriorated；Time interval is long, misses the optimal defrosting frequency for the pending thing that thaws.

Thawing apparatus 100 may also include detection module (not shown).Detection module can be configured to detection connection radio frequency The incidence wave signal and reflection wave signal of module 190 and the electrical wiring of radio-frequency antenna 130 occurs.And can according to incidence wave signal and The performance number of reflection wave signal, calculates the rf wave absorptivity of pending thing.Rf wave absorptivity can be the work(of incidence wave signal The ratio of the difference that the power that rate value subtracts reflection wave signal is worth to and the performance number of incidence wave signal.In some embodiments In, the performance number of incidence wave signal is a predetermined power value.In this embodiment, optimal defrosting frequency can be by reflection wave signal Performance number determines that the corresponding defrosting frequency of minimal reflection wave power value is optimal defrosting frequency.Predetermined power value can be 150~ 200W, such as 150W, 170W, 190W or 200W.Predetermined power value is most preferably 180W, using the power and coordinates foregoing solution Freeze control method, can be while the energy be saved so that the thawing apparatus 100 of the utility model has higher defrosting efficiency.

In some preferred embodiments, radio frequency occurs when module 190 can be configured in defrosting chamber 111 without pending thing not Work.Specifically, module 190 can occur according to connection radio frequency for detection module and the back wave of the electrical wiring of radio-frequency antenna 130 is believed Number performance number judge in defrosting chamber 111 without pending thing.When the performance number for the reflection wave signal that detection module detects is big When equal to a default no-load power value, radio frequency occurs module 190 and is stopped；When the back wave letter that detection module detects Number performance number when being less than default no-load power value, radio frequency occurs module 190 and works on.Thawing apparatus 100 can be configured to When the performance number for the reflection wave signal that detection module detects is more than or equal to default no-load power value, send vision and/or Audible signal reminds user unloaded.No-load power value can be current incidence wave signal performance number 70~90%, such as 70%, 80% or 90%.When the utility model is by defrosting chamber 111 without pending thing (including pending thing is very few), reminds and use Family is unloaded, and makes radio frequency that module 190 occur and be stopped, and avoids the generation of " sky is burnt " phenomenon, namely be that of avoiding radio frequency hair Give birth to 190 long-time unloaded operation of module and damage, reduce the failure rate of thawing apparatus 100, and avoid undesirably energy consumption Generation.
