Definitions

  • the present invention relates to a refrigerator, in particular to a refrigerator with a drawer door body.
  • a refrigerator as a household refrigerating/freezing device, is being currently used by a large majority of families.
  • the refrigerator is classified into many types, one type of which is designed as locating a freezing chamber on the upper side of the refrigerator and a refrigerating chamber on the lower side of the refrigerator, and another type of which is designed as locating a freezing chamber on the lower side of the refrigerator and a refrigerating chamber on the upper side of the refrigerator.
  • the door body of the freezing chamber is classified into several types of a single door body, a double door body, or a drawer type door body, etc.
  • a refrigerator commonly referred to as a French opposite-opening door refrigerator
  • the upper part of said refrigerator is a refrigerating chamber which is enclosed by a set of opposite-opening doors, and the lower part thereof is a freezing chamber which is enclosed by a drawer type door body.
  • the freezing chamber at the lower part of this type of refrigerator is generally designed to have a relatively large volume.
  • the inventor found that at least the following problem is present in the prior art: since the freezing chamber is merely provided with one drawer door body for accommodating objects, when pulling the drawer door body forward and taking out objects, the whole freezing chamber is open to external environment, resulting in excessive leakage of cool air, thereby prolonging the subsequent refrigerating process or frequently starting up a refrigerating system, so as to cause more consumption of electric energy.
  • JP H08 271132 discloses two drawer type doors which are arranged at a freezing chamber.
  • a partition plate to close a gap between the two doors is disposed at the lower side of the upper drawer type door.
  • the partition plate is formed in such a manner to be horizontally supported during opening of a door and brought into a vertical state when the door is closed..
  • JP 2004 020162 provides a refrigerator which comprises a drawing type door for opening/closing an opening part of a storage chamber partitioned by a front surface partitioning plate, L-cross-sectional support frames retaining a bottom surface on both sides of a container drawn out by the open door.
  • JP H10 054640 relates to a drawer-type refrigerating storage chamber, with installation of a seal member on a part projected to the inner side of a chamber on an inner circumferential side of a packing on an inner surface of a door.
  • the object of the present invention is to provide a refrigerator having one freezing chamber and plural drawing-pulling door bodies, said refrigerator having a reduced energy consumption.
  • This object is achieved by the features of independent claim 1. Further preferred embodiments of the invention are defined by the features of the dependent claims.
  • one embodiment of the present invention provides a refrigerator having a refrigerating chamber and a freezing chamber, wherein the freezing chamber is provided with plural drawer door bodies and sealing members; and the sealing member is used for sealing a clearance between adjacent drawer door bodies.
  • the internal structure of the freezing chamber is not reconstructed, but only a sealing member is added at the opening part. Therefore, each time that one drawer door body is opened for taking out an object, the opening of the freezing chamber laid open to the external environment is relatively small to reduce cool air leakage and energy consumption.
  • the sealing member is provided at the opening of the freezing chamber, and comprises a support frame and a decorative plate. Arranging the sealing member at the opening allows a simple structure and easy assembly. Moreover, the sealing member comprises a support frame and a decorative plate, with the support frame capable of having a better supporting function and the decorative plate abutting against the drawer door body for sealing.
  • a mounting trough is formed on the support frame; a thermal preservation bar is provided between the support frame and the decorative plate; and the thermal preservation bar is provided in the mounting trough of the support frame.
  • plural reinforced ribs are provided in the mounting trough of the support frame.
  • the strength of the support frame can be improved.
  • an auxiliary sealing bar is provided on the surface of the side of the thermal preservation bar adjacent to the decorative plate. In this way, the effects of thermal preservation and heat insulation can be improved better and the leakage of cool air from the freezing chamber can be further prevented.
  • through holes are provided on the end parts of the support frame and the decorative plate, and the support frame and the decorative plate are mounted via bolts passing through the through holes onto the opening of the freezing chamber of the refrigerator. In this way, the assembly structure is further simplified.
  • the drawer door bodies are divided into two sets.
  • the door bodies are made to be less, which allows more utilization of the space of the freezing chamber.
  • the refrigerating chamber is enclosed by a set of opposite-opening door bodies. So taking out the objects inside the refrigerating chamber is easy.
  • the refrigerating chamber is arranged at the upper part, and the freezing chamber is arranged at the lower part.
  • Plural drawer door bodies are provided in the freezing chamber and a sealing member is provided between adjacent drawer door bodies.
  • only one freezing chamber is provided, which facilitates the overall design of the refrigerator and the layout of the refrigeration units; and on the other hand, plural drawer door bodies are provided, each of which can be opened and closed independently.
  • the freezing chamber only has an opening part corresponding to the drawer door body opening to the external environment, thereby reducing cool air leakage and accordingly reducing energy consumption.
  • providing plural drawer door bodies means that plural drawers are available, such that the objects are accommodated more assortatively, for facilitating utilization for a user.
  • the so-called left side and right side represent the left hand side and the right hand side of a person facing the refrigerator
  • the upper side and the lower side represent an upper side and a lower side based on human sensory feeling.
  • a refrigerator 1 of the present invention Said refrigerator 1 is commonly called as a French refrigerator, viz. the upper part of the refrigerator 1 is a refrigerating chamber 2, which, thus, facilitates operation.

  • the lower part of the refrigerator 1 is a freezing chamber 3, which is also shown in Fig. 2 .
  • the freezing chamber 3 of the refrigerator 1 can also be located at the upper part.
  • the opening of the freezing chamber 3 is enclosed by two drawer door bodies 7, 8.
  • the drawer door body of the freezing chamber 3 can be divided into three or more drawer door bodies.
  • said freezing chamber 3 is a single freezing chamber.
  • said freezing chamber 3 performs the refrigeration by one refrigeration unit (no shown in the figure).
  • the spaces corresponding to the above two drawer door bodies are communicated with each other.
  • a cool drink supply mechanism is provided at the left door body 2a of the opposite-opening door bodies 2a, 2b. Since the mechanism is only slightly related with the inventive key of the present invention, the description related to the mechanism is omitted.
  • one embodiment of the present invention provides a refrigerator 1 comprising a refrigerating chamber 2 and a freezing chamber 3, wherein the freezing chamber 3 is provided with plural drawer door bodies 7, 8 and a sealing member 5; and the sealing member 5 is used for sealing a clearance between the adjacent drawer door bodies 7, 8.
  • the opening of the freezing chamber 3 only has the part corresponding to the drawer door body opening to the external environment, thereby reducing cool air leakage and accordingly reducing energy consumption.
  • Arranging plural drawer door bodies implies that plural drawers are available, such that the objects are accommodated more assortatively, facilitating utilization of the user.
  • the refrigerating chamber is located at the upper part and the freezing chamber 3 is located at the lower part.
  • the refrigerating chamber 2 with higher utilization rate is placed at the position of easy opening/closing, which facilitates usage.
