More particularly, the present invention relates to a low-pressure container, having an openable and closable door, for a refrigerator and a household or commercial refrigerator comprising such low-pressure container.
  • Chinese patent application CN1013243942A discloses a refrigeration appliance having a low-pressure storage unit (also called as a "vacuum storage unit").
  • the low-pressure storage unit is provided with a locking mechanism for locking a door of the low-pressure storage with a main body of the low-pressure storage when the door is closed, as well as a handle which is provided in a manner of linkage with the locking mechanism.
  • the handle is disposed at a front end of the door and comprises a rod body being located in front of the door and extending approximately across a width of the door, left and right supporting parts being connected to both ends of the rod body and extending backwardly as well as a handle operating part being connected at a central portion of the rod body.
  • the locking mechanism comprises a first mating part located on an end of the supporting part and a corresponding second mating part located on an outer surface of a side wall of the main body.
  • the rod body when the handle is operated, the rod body must be separated from a front surface of the door by a distance such that the rod body is rotatable about a rotational axis, which rotational axis is defined by a fulcrum shaft connected to the supporting part and extends in the door interior.
  • This increases the volume occupied by the low-pressure storage unit and thus reduces available space in the refrigeration appliance.
  • it is unaesthetic that the rod body is exposed in front of the storage unit.
  • Cisokaki39A discloses a storage unit.
  • This storage unit is compact in structure such that a first mating part of the storage unit can be fitted with a second mating part of the storage unit without extending outside of a side wall of a main body of the storage unit.
  • a locking mechanism is not necessarily held between the side wall of the main body and a corresponding inner wall of the storage compartment of the refrigeration appliance. This facilitates improving space utilization in the refrigeration appliance.
  • the locking mechanism or its locking effect need be provided or implemented at a vertical middle position of a front opening of the main body of the storage unit.
  • the position of the locking mechanism of the storage unit is securely connected to a rod body which is also securely connected to a handle, the position of the locking mechanism is restricted and at the same time the position of the handle on the door is also restricted.

  • the first mating part is driven by the handle via a transmission mechanism to rotate. Due to the transmission mechanism, the rotational axis of the handle is not coaxial with the rotational axis of the first mating part. That is, the two rotational axes are not the same rotational axis such that the problem in the prior art that the handle position is restricted by the locking mechanism position is solved.
  • the handle can be disposed upwardly or downwardly relative to the middle position of the door where it was disposed as previous. That is, according to technology requirements, the handle can be provided in a relatively free manner on the door.

  • the gear transmission mechanism is coupled to each first mating part, and the handle is used to drive the first mating part via the gear transmission mechanism to rotate.
  • the rotational axis of the handle is separated from two first mating parts, and is disposed upwardly or downwardly relative to a central position on the door where the handle was disposed as usual. Therefore, the handle is no longer limited by the position of the locking mechanism.

  • Figure 12b shows that the door 10 is locked with the main body 8.
  • the handle 32 is in the second position. As shown in figure 12b , when the handle 32 is rotated into the second position, the locking portion 46 is forced into the first mating part 34a and engaged tightly with it.
  • the transmission mechanism 90 comprises a first gear transmission part 911 which is secured on an end of the rod body 33 and a third gear transmission part 931 which forms an integral structure with the first mating part 34.
  • Both the first gear transmission part 911 and the third gear transmission part 931 are sector gears and meshed with each other.
  • the first gear transmission part 911 is rotated following rotation of the rod body 33 and at the same time the third gear transmission part 931 is gear-driven to rotate. Since the first mating part 34 forms the integral structure with the third gear transmission part 931, the first mating part 34 and the second mating part 44 are enabled to engage and lock with each other.
  • this embodiment may result in a technical effect that the first mating part 34 is located under the handle 32, it has two shortcomings than the previous embodiments: first, the extent to which the handle 32 is adjusted upwardly relative to the middle position of the door 10 where it was located as previous is reduced; second, because two adjacent gears are rotated reversely, it is necessary to re-design the mechanism between the handle 32 and the rod body 33, which is troublesome.
  • This embodiment described in this paragraph is advantageous by simple structure and easy implementation.
