When frost layer or thicker ice sheet in fins set 20, the heating device 311 works, and by the threaded rod 31 by heat transfer
To the fins set 20, so that the fins set 20 can be with defrost or change ice, and then effectively avoid in the fins set 20
Frost layer or ice sheet it is blocked up, influence the heat exchange efficiency of the evaporator 100.In the present embodiment, the heating device 311 is to add
Heated filament.It is described since the heating device 311 is directly to heat to the second fin 22 being arranged on the threaded rod 31
Second fin 22 is higher to the utilization rate of heat, so that the defrost period is shorter, power consumption is lower.
In other embodiments of the invention, the driving mechanism can also be independently arranged with the evaporator, for example, with institute
The tooling that the first, second fin 211,221 does not have direct connection matching relationship is stated, but can artificially be driven so that the
One, the mobile spacing between changing of the second fin 211,221.
Fig. 2 show another embodiment 200 of evaporator of the present invention.The evaporator 200 and the evaporator 100
Structure is substantially similar, the difference is that: the evaporator 200 is additionally provided with third fins set 23, the third fins set 23
Positioned at the side of second fins set 22.The third fins set 23 includes several third fins 231 being set side by side, described
Third fin 231 and first fin 211 interval are arranged.The sum of length of second fin 221, third fin 231 is no
Greater than the length of first fin 211.The driving mechanism 30 includes the first driving mechanism 301 and the second driving mechanism
302.First driving mechanism 31 drives second fins set 22 to move along the straight tube 11, second driving mechanism
The 32 driving third fins sets 23 are moved along the straight tube 11.First driving mechanism 301, the second driving mechanism 302
All include the motor 32 that threaded rod 31 and the driving threaded rod 31 rotate, is provided with heating device in the threaded rod 31
311.When in the fins set 20 frost layer or ice sheet be not very thick when, heating device 311 in second driving mechanism 302
Work, so can reduce power consumption while realizing defrost；When the frost layer or thicker ice sheet in the fins set 20, institute
State the first driving mechanism 301, the heating device 311 in the second driving mechanism 302 works at the same time, so as to quick defrost or change ice.
Fig. 6 show another embodiment 30 ' of driving mechanism, including motor (not shown), is mounted on the motor
Driving wheel 31 ', sliding block 33 ' and the connection driving wheel 31 ' and sliding block 33 ' connecting rod 32 ', second fins set
22, third fins set 23 is mounted on the sliding block 33 '.It is in fact possible to realize the embodiment party of the driving mechanism of aforementioned function
Formula is not just repeated in this one by one there are also very much.As long as second fins set 22, third fins set 23 may be implemented along institute
It states the mobile driving mechanism of straight tube 11 and belongs to equivalence changes of the invention.
The present invention also provides a kind of application methods of evaporator 200, include the following steps:
S1: when the compartment temperature is located at first interval, second fin 221 is located at two neighboring first fin
211 middle position, as shown in Figure 2；
S2: when the compartment temperature is located at second interval, the driving mechanism 30 drive first fins set 21 or
Second fins set 22 is mobile, so that second fin 221 deviates the middle position, as shown in Figure 4.
Wherein, the first interval is section [- 10 DEG C, 25 DEG C] or the subset in the section, and the second interval is section
The subset in [0 DEG C, 40 DEG C] or the section.Since the spacing between second fin 221 and adjacent first fin 211 increases,
It is blown upwards to be beneficial to circulated air from the bottom of evaporator.When second fin 221 and adjacent first fin 211 stick on
When together, effect is best.
Further, further include step S3: when the compartment temperature is located at first interval, the driving mechanism 30 is driven
The third fin 231 is mobile, so that the third fin 231 deviates the middle position between two neighboring first fin 211,
As shown in Figure 3.
Wherein, when the third fin 231 is sticked together with adjacent first fin 211, effect is best.
Further, further include step S4: when the compartment temperature is located at second interval, second fin 221,
Projection of three fins 231 on the straight tube 11 is not overlapped, as shown in Figure 4.Second fins set 22, third fins set at this time
23 form the wrong narrow spacing of fin structures of row's formula, and fin heat exchange area increases, and the heat transfer factor of wrong row's formula evaporator is with height, can be with
Effectively improve the heat exchange efficiency of evaporator.
It further, further include step S5: when close to preset temperature, (preset temperature is that user is compartment to the compartment temperature
The storage temperature of setting) when, the driving mechanism 30 drives second fin 221, third fin 231 all to deviate the centre
Position, and the projection of second fin 221, third fin 231 on the straight tube 11 is at least partly overlapped, such as Fig. 5 institute
Show.
During refrigeration for refrigerator, incipient stage refrigerator compartment temperature drop rate is very fast.When close to preset temperature,
Temperature drop rate is slower, and indoor steam starts frosting or icing on an evaporator, at this time second fin 221,
Third fin 231 deviates in the same direction, so that spacing increases between fin, the frosting on evaporator can be effectively reduced or the speed that freezes
Degree.
Further, further include step S6: the refrigerator is provided with food identification device；When food identification device identifies
Meat product is stored in the compartment, and when the temperature of the meat product is in 3rd interval, the driving mechanism 30 is driven
It moves second fin 221 and deviates the middle position.
Wherein, the 3rd interval is section [0 DEG C, 40 DEG C] or the subset in the section.
Further, further include step S7: being stored with meat product when food identification device identifies in the compartment, and
When the temperature of the meat product is in 3rd interval, the driving mechanism 30 drives second fin 221, third fin
231 deviate the middle position, and the projection of second fin 221, third fin 231 on the straight tube 11 is at least partly
It is overlapped.
Since the temperature of meat product is high, humidity is big, and fast cooling is needed, therefore evaporator is adjusted to wide spacing wing
Chip architecture can be effectively reduced windage, improve heat exchange efficiency, while can also reduce frosting or icing rate.
Compared to the prior art, the spacing of fin of evaporator 100,200 of the present invention is adjustable, so as to according to different operating conditions
Spacing of fin is adjusted, and then reduces frosting or the icing rate of evaporator, reduces windage when circulated air passes through fin, to mention
The heat exchange efficiency of high evaporator.
In particular, for those of ordinary skill in the art, made under the teachings of the present invention to be directed to
Equivalence changes of the invention should be included within the scope claimed in the patent scope of the present application.
