As shown in Figure 3 and Figure 4, in another preferred embodiment of the application, the heating element 4 setting is set in cabinet body
On standby door frame of box 201, wherein when door body 202 be closed when, the heating element 4 towards the mounting portion 1 and with the mounting portion 1
It is in contact.In this way, can effectively shorten the distance between heating element 4 and elastomeric seal portions 2, improve to elastomeric seal portions 2
Heating efficiency.
In another preferred embodiment of the application, opening is configured on the door frame of box 201 towards the installation
The groove body 201a in portion 1, the heating element 4 are embedded in groove body 201a.It should be noted that realize to the heating element 4
Installation and fixation, avoid heating element 4 can the case where being fallen off from groove body 201a, then can be in the inside of groove body 201a
Add buckle, that is, so that buckle is arranged on the inner sidewall of groove body 201a, then and the lower end surface of buckle is made to be pressed on heating
The upper surface of component 4, this way it is possible to realize the fixation to the heating element 4.
As shown in Figure 3 and Figure 4, in the preferred embodiment of the application, when the door body 202 of the case equipment is closed
After on the cabinet 200 of the case equipment, which mutually staggers with the magnetic part 11 in mounting portion 1.In this way,
After door body 202 closes on cabinet 200, avoid causing because there is the case where partly overlapping between magnetic part 11 and heating element 4
Reduce magnetic part 11 attraction area, further, it is ensured that the attraction of magnetic part 11 so that door body 202 closure when, energy
It is enough to be pull-in on cabinet 200 securely, to reach preferable sealing effect.
As shown in figure 5, also providing a kind of door seal structure heating means according to the third aspect of the application, comprising:
Step S1 detects environment temperature T locating for door seal structure0。
Step S2 judges environment temperature T0Whether the first preset temperature T is lower than1.If so, S3 is entered step, if it is not, weight
Multiple step S2.Wherein, first preset temperature T1Less than or equal to 10 DEG C.First preset temperature T1Refer to and judges elastomeric seal portions 2
Whether the critical-temperature of stiff state is in.That is, environment temperature T0Higher than first preset temperature T1, which has
Elasticity, conversely, if environment temperature T0Lower than the first preset temperature T1, then elastomeric seal portions 2 are in stiff state.
Step S3, if environment temperature T0Lower than first preset temperature T1, then heating element 4 is heated and heats elastic close
Envelope portion 2.It should be noted that the heating method can be continuous heating or intermittent heat, wherein intermittent heat refers to one section of heating
Time stops a period of time, then reheats a period of time, then stops a period of time, repeatedly.The time of heating be greater than etc.
In 5s (second) and it is less than or equal to 600s (second), in actual use, can determines that the time of heating, the time are not easy according to experimental data
It is too long, in order to avoid keep the temperature of door seal structure excessively high, cause the service life for influencing door seal structure and reduce magnetic part 11
Magnetism.
Step S4 judges environment temperature T locating for door seal structure0Whether second preset temperature T is reached2。
Step S5, if environment temperature T locating for the door seal structure0Reach second preset temperature T2, then heating element 4
Elastomeric seal portions 2 are heated in stopping, and the first preset temperature T1 is less than the second preset temperature T2.In this way, working as gasket knot
After environment temperature locating for structure reaches the second preset temperature T2, it was determined that the elastomeric seal portions 2, which have been restored to, to be had
The state of elasticity, it is thereby advantageously ensured that leakproofness of the elastomeric seal portions 2 to door body 202.
In another preferred embodiment, if environment temperature T0Lower than the first preset temperature T1, then in heating element 4
Before being heated and heating elastomeric seal portions 2, this method further include: judge environment temperature T0Lower than the first preset temperature T1When
Between whether reach the first preset time t1, if so, heating element 4 is heated and heats elastomeric seal portions 2.It should be noted that
First preset time t1Preferably 1~72h (hour).In this way, heating element 4 can be effectively avoided by continually start and stop,
Cause the service life for reducing heating element 4.
It should be noted that if environment temperature T0Lower than the first preset temperature T1Time be not up to the first preset time t1,
Then this method terminates.
As shown in fig. 6, also providing a kind of door seal structure heating means according to the fourth aspect of the application, comprising:
Step S10 detects the temperature T of door seal structure.
Step S20, judges whether the temperature T of door seal structure is lower than third preset temperature T3.If so, entering step
S30, if otherwise repeating step S20.
Step S30, if the temperature T of the door seal structure is lower than third preset temperature T3, then heating element 4 is heated and heats
Elastomeric seal portions 2.
Step S40, judges whether the temperature of elastomeric seal portions 2 reaches the 4th preset temperature T4。
Step S50, if the temperature of the elastomeric seal portions 2 reaches the 4th preset temperature T4, then heating element 4 stops to elasticity
Sealing 2 is heated, the 4th preset temperature T4Greater than third preset temperature T3.Wherein, third preset temperature T3Less than or equal to 10
DEG C, the 4th preset temperature T4Greater than 10 DEG C.
Wherein, the 4th preset temperature T4Temperature deviation value be μ, the 4th preset temperature T4Temperature fluctuation range can be T4-
μ to T4+μ.In this way, that is, the 4th preset temperature T4Temperature in T4- μ to T4It just will start 4 work of heating element other than the range of+μ
Make.
As the 4th preset temperature T4In T4- μ arrives T4Within+μ range, it can all stop the work of heating element 4, such purpose
It is to avoid heating element 4 because continually starting work and shutting down work, so that being had an impact to the service life of heating element 4.
Wherein, the magnitude range of temperature deviation value μ, which is preferably less than, is equal to 2 DEG C.
In conclusion the elastomeric seal portions 2 when the environment temperature locating for the door seal structure is lower, in the door seal structure
It tends to become stiff, for the elasticity for ensuring the elastomeric seal portions 2, then by adding the heating element 4 to elastic packing
Portion 2 is heated, so that elastomeric seal portions 2 are restored to original elastic stage by stiff state, further, when
After door body 202 closes on door frame of box 201, which can play preferable sealing function, that is, effectively keep away
Exempt from extraneous high temperature air or Cryogenic air to enter inside cabinet 200, meanwhile, the sky being also effectively prevented from inside cabinet 200
Gas spills into the outside of cabinet 200.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
