After door body 2 seal case 1, because the temperature in refrigerator-freezer is lower, therefore air pressure can reduce gradually, and there is certain pressure reduction between external pressure.The first paragraph (the first pipe 31 namely embodiment) from its first end towards the second end definite length extended of barometric pipe 3 is configured to extend obliquely, here, it should be noted that, in the figure 2 example, barometric pipe 3 is roughly bend pipe, therefore the first paragraph of barometric pipe 3 can be understood as be along the trend of barometric pipe 3 from the outside opening of barometric pipe 3 inwardly opening extend the body portion of certain length.
As shown in Figure 2, first paragraph is configured to extend obliquely, and particularly, first paragraph extends obliquely from external interface.Rolling member 34 is rollably located in first paragraph to be suitable for closing external interface when refrigerator-freezer inside and outside differential pressure is less than predetermined value.
In other words, because first paragraph extends obliquely, therefore when refrigerator-freezer inside and outside differential pressure is roughly equal, namely the least significant end being positioned at first paragraph is positioned at external interface and sentences closed external interface by rolling member 34, thus keeps apart inner for refrigerator-freezer with outside atmosphere.
Along with the increase of door body 2 off-period, air pressure in refrigerator-freezer reduces gradually, after air pressure reduces certain value, the gravity of rolling member 34 will be overcome under the effect that pressure reduction is made a concerted effort, thus promotion rolling member 34 scrolls up, external interface and internal interface conducting thus, makes refrigerator-freezer internal pressure and external pressure balance, and rolling member 34 is rolled into initial position and sealed external interface again due to gravity.
According to the refrigerator-freezer of the embodiment of the present invention, by arranging barometric pipe 3 and rolling member 34, when refrigerator-freezer inside and outside differential pressure reaches certain value, rolling member 34 will leave external interface to make to be communicated with inside and outside refrigerator-freezer, thus balance refrigerator-freezer inside and outside differential pressure, facilitate user to open the door.And finger or elongated parts, before enabling, also can stretch in first paragraph from external interface and promote rolling member 34, realize the function of manual adjustments inside and outside differential pressure, facilitate door opening action by user.
