DETAILED DESCRIPTION
[0032] The foregoing objectives, features and advantages of the
present invention will become more apparent from the following
detailed description of specific embodiments of the invention in
conjunction with the accompanying drawings.
[0033] Referring to FIG. 1, the present embodiment provides a
refrigeration appliance R and a heat insulation door D for the
refrigeration appliance R. The refrigeration appliance R may be a
refrigerator or other electric appliances with a refrigeration
space.
[0034] As shown in FIG. 2, FIG. 3 and FIG. 4, the heat insulation
door D comprises a door body 10 of a multilayer structure and a
doorframe 20. The door body 10 comprises a heat insulation vacuum
glass module 11, wherein the vacuum glass module 11 comprises
superposed first glass 11a and second glass 11b having a first
interval 10a, and the first glass 11a is located in front of the
second glass 11b along the front-to-rear direction X of the door.
In addition, the door body 10 further comprises a front decoration
plate 12 located in front of the vacuum glass module 11 and used
for shielding the first glass 11a.
[0035] It shall be noted that in the present application, without
otherwise specified, the "front-to-rear direction" refers to the
front-to-rear direction of the door, i.e. a thickness direction of
the door. The "front" is a direction pointing to a front surface of
the door, and the "back" is a direction pointing to a back surface
of the door. The "inner side" refers to one side, close to the
center of the door body, of a plane in which the door body is
located, i.e. one side away from the edge of the door.
[0036] In a width and/or length direction of the first glass 11A,
the front decoration plate 12 is provided with a protruding portion
12a that extends out of the edge of the vacuum glass module 11, and
FIG. 2 only shows the protruding portion 12a on one side. The
protruding portion 12a can be used for shielding other parts, for
example, can be used for partially or completely shielding the
doorframe 20. In the present embodiment, along the front-to-rear
direction of the door, the protruding portion 12a completely
shields the doorframe 20.
[0037] The present invention has the advantages that the front
decoration plate is disposed in front of the vacuum glass module,
the front decoration plate shields the vacuum glass module and
extends out of the edge of the vacuum glass module at least along
one direction, so that on one hand, the front decoration plate can
play a decoration role to improve the appearance attractiveness of
the heat insulation door, and can also be used for protecting the
glass module to prevent the glass module from being directly
exposed to a range that a user can reach, thereby preventing the
breaking probability, and also preventing the broken glass module
from injuring the user. On the other hand, the protruding portion
can be used for shielding a doorframe, so that the doorframe is
concealed behind the door, and the attractiveness is better.
[0038] The front decoration plate 12 may be a toughened glass
plate, a colorful crystal glass plate or a plastic plate, and is
preferably the colorful crystal glass plate.
[0039] In the door body 10 of a multilayer structure, a sealing
portion is disposed between two adjacent layer structures that are
spaced so as to form a heat insulation space between two adjacent
layer structures. As shown in FIG. 3, a first sealing portion S1 is
disposed between an edge of the first glass 11a and an edge of the
second glass 11b in the vacuum glass module 11 to enable the first
interval 10a to form an enclosed space. Generally speaking, the
first sealing portion S1 is in an annular shape surrounding the
edge of the vacuum glass module 11.
[0040] Meanwhile, there is a second interval 10b between the front
decoration plate 12 and the vacuum glass module 11. A second
sealing portion S2 is disposed between an edge of the front
decoration plate 12 and an edge of the vacuum glass module 11 to
enable the second interval 10b to form an enclosed space. The first
sealing portion S2 is also basically in an annular shape
surrounding the vacuum glass module 11. In comparison to the first
interval 10a between the first glass 11a and the second glass 11b
in the vacuum glass module 11, the second interval 10b between the
front decoration plate 12 and the vacuum glass module 11 can be
slightly bigger so as to form a hollow space.
[0041] Generally speaking, the second sealing portion S2 is also in
an annular shape surrounding the edge of the vacuum glass module
11. It can be seen from FIG. 3 that along the front-to-rear
direction of the door, projections of the second sealing portion S2
and the first sealing portion S1 on a same edge are at least
partially overlapped.
[0042] As shown in FIG. 2 to FIG. 4, the door body 10 further
comprises a rear protective layer 13 located behind the second
glass 11b along the front-to-rear direction X and used for
shielding the second glass 11b. The rear protective layer 13 is
used for protecting the vacuum glass module 11 at the back thereof
and can be used as a decorative layer on the inner side of the heat
insulation door D. The rear protective layer 13 may be a toughened
glass layer, a colorful crystal glass layer, or a plastic
plate.
[0043] The rear protective layer 13 may be disposed at an interval
from the vacuum glass module 11 and a third interval 10c is formed.
A third sealing portion S3 is disposed between an edge of the rear
protective layer 13 and an edge of the vacuum glass module 11 to
enable the third interval 10c to form an enclosed space. In
general, the third sealing portion S3 is also basically in an
annular shape surrounding the vacuum glass module 11.
[0044] It shall be noted that in a width and/or length direction of
the first glass 11a, i.e. in the length or width direction of the
door body 10, the protruding portion 12a of the front decoration
plate 12 extends out of the rear protective layer 13. It can be
seen from FIG. 2 that the dimension and the shape of the rear
protective layer 13 are basically consistent with the dimension and
the shape of the vacuum glass module 11 so as to completely shield
the vacuum glass module 11.
[0045] It shall be noted that the intervals between the front
decoration plate 12 and the vacuum glass module 11 and between the
rear protection layer 13 and the vacuum glass module 11 may be an
air layer or an inert gas layer.
[0046] In some other embodiments, as shown in FIG. 5, the rear
protective layer 13 may also be bonded to the vacuum glass module
11. In addition, the rear protective layer 13 may also comprise a
protective film that adheres to the second glass 11b, or may be a
protective film that adheres to the second glass 11b.
[0047] As shown in FIG. 4, the doorframe 20 surrounds the vacuum
glass module 11, the doorframe 20 can be divided into a side frame
portion 21 and a rear frame portion 22, the side frame portion 21
is located outside a peripheral surface of the vacuum glass module
11, and the rear frame portion 22 is located at the back of the
vacuum glass module 11 along the front-to-rear direction X of the
door.
[0048] The doorframe 20 is internally provided with a first
cooperative wall 21a located in front of the rear frame portion 22
and located at the back of the protruding portion 12a, a second
cooperative wall 22a facing the back of the vacuum glass module 11,
and a connecting wall 21b connecting the first cooperative wall 21a
and the second cooperative wall 22a.
[0049] Specifically, the first cooperative wall 21a and the
connecting wall 21b are disposed on the side frame portion 21, and
the second cooperative wall 22a is disposed on the rear frame
portion 22. The connecting wall 21b is located on the inner side of
the side frame portion 21 and the outer side of the rear frame
portion 22 and surrounds a peripheral edge of the vacuum glass
module 11. Along the front-to-rear direction X, the vacuum glass
module 11 and the rear protective layer 13 are located between the
first cooperative wall 21a and the second cooperative wall 22a. The
protruding portion 12a is connected to the first cooperative wall
21a, and the vacuum glass module 11 may be directly or indirectly
connected to the second cooperative wall 22a. In the present
embodiment, the rear frame portion 22 and the door body 10 are
bonded by using glue through the second cooperative wall 22a.
[0050] The second cooperative wall 22a covers all sealing areas,
i.e. the first sealing portion S1, the second sealing portion S2
and the third sealing portion S3 in the door body.
[0051] Although the present invention is disclosed as above, the
present invention is not limited thereto. Various changes and
modifications may be made by any technical skilled in the art
without departing from the spirit and scope of the present
invention, and the protection scope of the present invention shall
be defined by the scope of the claims.
