[0001] The present invention refers to a modular refrigerating component, preferably to
a refrigerating component for a so called
no-frost freezing apparatus, comprising an evaporator with a heater, an insulation enclosing
the evaporator, a plate for condensate drainage, an attachment for condensate drainage
with a heater, and a fan, where said component is assembled separately and incorporated
into the freezing apparatus at a later time.
[0002] Freezing apparatuses as mentioned above are known and in use, however, they have
several drawbacks. Particularly, it is a characteristic with all known refrigerating
components that the evaporator of the refrigerating component is connected with a
return pipe on the back side i.e. the side facing the back of the freezing apparatus.
For this reason a hole must be provided in the wall of the apparatus through which
said return pipe is lead resulting in accelerated deterioration of the insulation.
In addition, the assembling and maintenance of the modular refrigerating component
is rendered difficult due to the inaccessibility of the return pipe.
[0003] It is the object of the present invention to create a modular refrigerating component
which will remedy the drawbacks of the known solutions.
[0004] A refrigerating component according to the invention is preferably intended for use
with so called
no-frost freezing apparatus. This is a kind of apparatus where ice does not collect on the
refrigerating component but thaws itself automatically, and the water is lead away
via a suitable drainage.
[0005] The object as set above is solved, according to the invention, by that both a feeding
pipe of cooling fluid and a return pipe of cooling fluid, respectively, can be connected
to the refrigerating component on the side facing the door of a freezing apparatus.
Thereby, the access to connecting points is significantly facilitated, both with the
assembling of the refrigerating component and with potential repair or replacement,
respectively. Here said pipes for the cooling fluid leading from a compressor to connecting
points on the refrigerating component are lead in the insulation of the hack and top,
and drop toward the refrigerating component from the top directly in front of said
connecting points.
[0006] Further, it is provided according to the invention that on the side of the refrigerating
component facing the back and away from the top a fan can be inserted through an aperture
in the refrigerating component. Thus, quick and easy replacement of the fan is achieved.
[0007] An attachment of the refrigerating component for condensate drainage facing the back
is lead into the drainage which, however, is the subject of another patent application.
Said condensate drainage is lead in the insulation of the back of the freezing apparatus.
[0008] The present invention will become more fully understood from the detailed description
given hereinafter and the accompanying drawing, wherein a vertical cross-section of
a so called
no-frost freezing apparatus is schematically shown.
[0009] A freezing apparatus comprises a door 1 which closes a housing 2 in which there is
arranged vertically oriented plurality of drawers 3 for the storage of food. In the
area of a bottom 4 of the housing 2 is arranged a compressor 5 provided for maintaining
the chosen temperature inside the freezing apparatus. In the area directly under a
top 6 of the housing 2 there is arranged a refrigerating component 7 which is connected
with a feeding pipe 8 and a return pipe 9 for a cooling fluid on one hand, and with
an attachment 10 for drainage of the melted ice is connected with a water and/or condensate
drain 11 on the other. The refrigerating component 7 is further provided with a fan
12.
[0010] According to the invention it is provided for that both the feeding pipe 8 and the
return pipe 9, respectively, are connected to the refrigerating component 7 at the
front side thereof i.e. on the side facing the door 1 of the freezing apparatus. The
pipes 8, 9 are lead from the compressor 5 forward in the insulation of the freezing
apparatus in a manner that, at first, they extend vertically in the back 13 of the
freezing apparatus, and afterwards they extend horizontally in the insulation of the
top 6 where they drop vertically down in the area of the front of the refrigerating
component 7 i.e. the part thereof facing the door 1 of the freezing apparatus. The
connection of the feeding pipe 8 and the return pipe 9 of the cooling fluid with the
refrigerating component 7 is significantly facilitated both with the assembling of
the refrigerating component 7 into the freezing apparatus and with potential maintenance
or replacement of the refrigerating component, respectively. The connection of the
pipes 8, 9 with the refrigerating component 7 is known per se and thus not described
in detail.
[0011] A fan 12 is arranged in the area of the back portion of the refrigerating component
7 i.e. the portion facing the back 13 of the freezing apparatus, said fan 12 can be
conveniently inserted into the refrigerating component 7 through an aperture 14 on
the side facing away from the top 6. According to the invention it is provided for
that the fan 12 can be inserted into the refrigerating component 7 in a manner that,
when replacing a fan for example, the refrigerating component 7 remains fixed in its
position and there is no need whatsoever either to move it or remove it from the freezing
apparatus.
[0012] The refrigerating component 7 comprises in said back portion an attachment 10 for
draining of the water and/or condensate, said attachment being lead into a drain 11
extending in the insulation of the back 13 of the freezing apparatus. Said drain 11
is the subject of a separate patent application and thus it is not described in detail.
