[0001] The present invention relates to a back-loadable refrigeration cabinet and more especially
the invention relates to a back-loadable refrigeration cabinet with sliding doors
on the non-customer side of the cabinet according to the preamble of claim 1.
[0002] Different types of refrigeration solutions for grocery stores are known from prior
art. Refrigerated, back-loadable cabinets are employed to allow customers to access
groceries and other refrigerated items from the front of the case without the obstruction
of a door. The refrigerated items are loaded onto the cabinet shelves from the back
of the cabinet to allow restocking without disturbing the customers. These types of
cabinets typically comprise frame for shelves and cooling equipment with blowing devices
to create cooling air flows to the interior of the cabinet in order to keep inside
of the cabinet and the products inside in the required temperature to ensure the required
shelf life of the products. The cooling equipment typically comprises an evaporator
and a blower located at equipment space below the refrigerated space with shelves
for products, which leads to high lower front edge / wall of the equipment space thus
reducing product space. The height of the lower front edge in prior art arrangements
has typically been at least 395 mm. In prior art arrangements air ducts leading the
cooling air to the product space lead from the equipment space to the shelf structures
such that air is blown from below the shelf and thus the locations of the shelves
are fixed.
[0003] The back side of the cabinet is typically openable to a cooled storage room located
behind the cabinet to allow access to cabinet when loading is required and it may
be provided with curtains or doors, for example narrow sliding doors to close the
back of the cabinet when loading is not required for efficient functioning of the
cooling equipment and preventing the view from the customer side to the cooled storage
and thus this has simultaneous led to poor visibility from the cooled storage space
into the refrigerated cabinet and thus the need for filling in products has required
the personnel to either open the curtains or doors or to do the checking of the product
amounts in the refrigerated cabinet form the customer side.
[0004] In patent publication
US 3812684 is disclosed a back-loadable refrigeration cabinet comprising a frame and cooling
devices, which frame is open to the front of the cabinet and forms a product space
and has a back wall structure comprising sliding doors, which cooling devices are
located in an equipment space provided in the frame and connected to at least one
air duct for providing cooled air to the product space.
[0005] An object of the present invention is to create a back-loadable refrigeration cabinet
in which the disadvantages of prior art arrangements are eliminated or at least minimized.
[0006] A particular object of the invention is to create a back-loadable refrigeration cabinet,
in which the relation of the product space to the equipment space is greater than
in prior art arrangements.
[0007] A particular object of the invention is to create a back-loadable refrigeration cabinet,
in which shelve locations in the product space are modifiable.
[0008] A particular object of the invention is to create a back-loadable refrigeration cabinet,
in which visibility from the cooled storage into the cabinet is improved.
[0009] In order to achieve the above objects and those that will come apparent later the
back-loadable refrigeration cabinet is mainly characterized by the features of the
characterizing part of claim 1. Advantageous embodiments and features are defined
in dependent claims.
[0010] According to the invention the back-loadable refrigeration cabinet comprises a frame
and cooling devices, which frame is open to the front of the cabinet and forms a product
space and has a back wall structure comprising sliding doors, which cooling devices
are located in an equipment space provided in the frame and connected to at least
one air duct for providing cooled air to the product space. The frame has a bottom
part with a front edge having a height to the bottom of the product space from floor
level 100 - 380 mm, advantageously 300 - 350 mm. By this more product space is achieved
and simultaneously the front edge line with other store cabinet can easily be standardized
without loss of product space in other types of store cabinets.
[0011] Advantageously the low front edge of the back-loadable according to the invention
is provided by locating cooling devices such as an evaporator and a blower into the
equipment space on the bottom part or in the ceiling part of the cabinet such that
lowest possible dimension of the front edge can be achieved for example locating the
devices to a longest dimension horizontally extending position.
[0012] According to an advantageous feature of the invention the sliding doors are transparent
material by which very good visibility from the cooled storage into the cabinet for
checking the need of filling in products to the product space is achieved.
[0013] According to an advantageous feature of the invention the sliding doors cover at
least 75 % of the back wall surface area seen from the product space and/or at least
55 % of the back wall surface area seen from the cooled storage so that good accessibility
from the cooled storage room located behind the back-loadable refrigeration cabinet
to the product space is achieved.
[0014] According to an advantageous feature of the invention the shelves for products are
movably attached to the back wall structure of the back-loadable refrigeration cabinet.
[0015] In the following the invention is described in detail with reference to the accompanying
drawings, in which
in figures 1 - 3 is shown schematically one advantageous example of a back-loadable
refrigeration cabinet,
in figure 4 is shown examples of an equipment space location alternatives in an advantageous
example of a back-loadable refrigeration cabinet and
in figure 5 is shown a detail showing air ducts leading the cooling air to a product
space of an example of a back-loadable refrigeration cabinet.
[0016] During the course of the following description of figures 1 - 5 like numbers and
signs will be used to identify like elements according to the different views which
illustrate the invention.
[0017] In figures 1 - 3 shown a schematical example of back-loadable refrigeration cabinet
10 comprises a frame 11. The frame 11 has a horizontally extending bottom part 11
A, a vertically from back end of the bottom part extending back wall structure 11
B and a horizontally from the upper end of the back wall structure 11 B extending
ceiling part 14 so that side view of the cabinet 10 has a turned C-like shape, in
which the bottom part 11 A and the ceiling part 14 form the arms of the C-shape and
the back wall structure 11 B forms the connecting part between the arms 11 A, 14.
Thus the refrigerated, back-loadable cabinet 10 can be employed to allow customers
to access groceries and other refrigerated products from the refrigerated product
space 13 via the front of the cabinet 10.
[0018] On the bottom part 11 A in the frame 11 in the example of figures 1 - 3 is located
an equipment space 12 formed as an openable casing into which equipment space 12 cooling
devices such as an evaporator and a blower are located advantageously to a longest
dimension horizontally extending position so that the front edge of the cabinet up
to the uppermost part of the equipment space 12 casing i.e. to the bottom 17 of the
product space 13 from floor level has height H 100 - 380 mm advantageously the height
H is 300 - 350 mm. Upwards from the equipment space 12 is formed the product space
13 that is open to the front and limited by the back wall structure 11 B and the ceiling
part 14.
[0019] The shelves 16 for products are movably attached to the back wall structure 11 B
so that the shelve locations are modifiable in the cabinet 10, which thus provides
many possibilities for product placing. The shelves 16 are attached movably to the
back wall structure 11 B by manners known per se. The shelves may be positioned horizontally
or slightly inclined lowering towards the front side of the cabinet 10. Each shelf
may have a front barrier 16A to prevent the products from falling off the front edge
of the shelf, especially when inclined shelves are utilized. The shelves 16 may also
have support part / parts 16B to secure the weight-carrying capacity of the shelf.
[0020] The refrigerated items are loaded onto the cabinet shelves 16 from the back of the
cabinet 10 to allow restocking without disturbing the customers. The back wall structure
11 B comprises sliding doors 15 that cover at least 75 % of the back wall surface
area seen from the product space 13 and/or at least 55 % of the back wall surface
area seen from the cooled storage so that good accessibility from the cooled storage
room located behind the back-loadable refrigeration cabinet 10 is achieved. Advantageously
the sliding doors 15 are of transparent material by which very good visibility from
the cooled storage into the cabinet 10 for checking the need of filling in products
onto the shelves 16 is achieved.
[0021] In figure 4 is shown by dashed lines two alternatives 12A; 12B of the equipment space
12 locations in the cabinet 10. In alternative 12A of the equipment space 12 is locate
on the bottom part 11 A of the cabinet 10. In alternative 12B of the equipment space
12 is formed in the ceiling part 14.
[0022] In figure 5 is shown a detail showing air ducts 18 leading the cooling air to a product
space 13 of an example of a back-loadable refrigeration cabinet 10. The air ducts
18 leading the cooling air to the product space 13 are located in connection with
the back wall structure such that cooled air is led to the product space through air
duct openings 18A in the back wall structure and through air duct openings 18B in
connection with the console 19 for attaching the support parts 16B of the shelves
16.
