Definitions

  • the invention relates to a multi-temperature refrigerator according to the preamble of claim 1.
  • a refrigerator is known from US-A-4 539 819.
  • thermostatically controlled control flaps for regulating the different operating temperatures prevailing in the various subjects in the air ducts running in the walls, floors or ceilings of the heat-insulated housing.
  • the invention has for its object to improve the structure of the cooling devices specified in the introduction by simple measures and in particular to solve the problems associated with the installation of the control flaps and their drive cheap.
  • the distributor as an essentially cuboid body is formed, which is fitted in the rear area under the intermediate floor receiving the heat exchanger in the niche formed by the side walls and the rear wall of the housing and is provided with connection openings for the air channels running there.
  • the plug of specifically heavy cold air that forms in a siphon of this type prevents in a simple manner that warmer air rising in the channel can reach the compartment above it.
  • the channels are equipped with pocket-shaped separators for condensation water located in front of the control flaps in the direction of flow.
  • a construction has proven to be particularly favorable according to which the distributor is equipped with a lighting device for the compartment accommodating it.
  • a multi-temperature refrigerator 10 with a heat-insulated housing 11 has compartments of different temperatures thermally separated from one another by intermediate shelves 12 and 13 or a separating plate 14 - such as a freezer compartment 15, a so-called zero-degree compartment 16 and at temperatures of + 5 ° C and + 10 ° C operated cooling compartments 17 and 18.
  • the freezer compartment 15 is arranged on top in the housing 10, while the zero-degree compartment 16 and the cooling compartments 17 and 18 operated at + 5 ° C. and + 10 ° C. are in the order listed below.
  • the individual compartments of different temperatures can be closed with heat-insulated doors 19 and 19 'or with heat-insulated front panels 20 and 20' on drawer-like pull-outs in the cooling compartments 17 and 18 below, which are not shown here.
  • the multi-temperature refrigerator 10 is equipped in a known manner with an electric motor-driven compressor cooling unit, the individual components of which, for the sake of simplicity, only the encapsulated motor compressor 22 arranged in a machine compartment 21 in the base of the heat-insulated housing 10 and the one in the heat-insulated intermediate floor 12 between the freezer compartment 15 and the zero-degree compartment 16 are shown cold-side heat exchangers 23 designed as lamella evaporators. This is forced-ventilated by means of an electric motor-operated fan 24.
  • the intermediate floor 12 between the freezer compartment 15 and the zero-degree compartment 16 is for receiving the heat exchanger 23 and the blower 24 and various auxiliary units, not shown, such as a defrost heater and the like.
  • air channels 25 in which the individual units are concealed and invisible from the outside.
  • the temperature level in the individual compartments of different temperatures is maintained with the aid of the cold air flow conveyed by the blower 24 via the heat exchanger 23, which is conducted via air channels 26 and 27 arranged in the side walls or the rear wall of the housing 10.
  • the air supply to the individual compartments of different temperatures is controlled by thermostatically controlled regulating elements in the form of flap thermostats described in detail below controlled with controller flaps in the channels.
  • the pressure-side air ducts 27 are formed in the illustrated and described embodiment by a trough-like molded part 28 arranged in the rear wall of the heat-insulated housing 10 and shown as an individual part in FIGS. 8 and 9, which with its open side from behind against the rear wall of the individual Inner container enclosing compartments of different temperatures and there corresponds with corresponding outlet openings.
  • the trough-like molded part 28 receiving the pressure-side air ducts 27, which is used at the same time for mounting the blower 24 and is equipped for this purpose with a number of circularly arranged fastening pins 29, is described in more detail below in connection with FIGS. 8 and 9 and in explained its function.
  • a valve thermostat which is used in a distributor 30 which can be inserted into the housing 10 as a preassembled unit serves as the usual type of regulator with regulator flaps 31, each with an electromotive drive 32 also arranged in the distributor 30 (see FIGS. 4 and 6) ) are driven.
  • the same position numbers are used for corresponding parts.
  • the distributor 30 is designed as a substantially cuboid body, which is fitted in the rear area under the intermediate floor 12 receiving the heat exchanger 23 and the fan 24 in the niche formed by the side walls and the rear wall of the housing 10 and with connection openings 33, 34 and 35 is equipped for the corresponding air ducts.
  • the distributor piece 30 is formed from two nested and tightly interlocked mold parts 36 and 37 made of rigid plastic foam, which accommodate cavities for air channels 38 or chambers 39 for installing the electromotive drive 32 of the controller flaps 31.
  • the distributor 30 On its front side, the distributor 30 is covered with a plastic shell 40, in the recessed lower area of which outlet openings 41 are arranged for the air channels 38 emerging here.
  • the distributor 30 On the lower rear edge of the plastic shell 40 there are also eyes 42 which are used to fasten the distributor 30 to the rear wall of the housing 10 and serve in the trough-like molded part 28 with the air channels 27 therein.
  • the air channels 38 located in the distributor 30 in the flow direction behind the control flaps 31 of the flap thermostats are siphon-like and are provided with a recess 43 for this purpose, into each of which a partition protrudes from above .
  • the distributor 30 is also equipped with a lighting device arranged laterally in a recess 44 in the form of a lamp socket provided with an incandescent lamp 45 for the compartment 16 assigned to it.
  • the electrical supply lines for the energy supply of the electromotive drives 32 of the flap thermostats are sunk on the back of the distributor 30 in a channel 46, from which they emerge laterally behind the lighting device. They are combined with their electrical leads to form a cable harness 47 which is provided with a common plug 48, the counterpart of which is not shown, is located in a wall of the housing 10.
  • connection openings 33 to 34 of the distributor 30 are each surrounded by sealing frames 49 and 50, which consist of a sponge-like elastic material and ensure an airtight connection to the associated connections of the air channels in the rear wall of the housing 10 and in the intermediate floor 12.
  • the sealing frames also perform the task of occasionally absorbing and binding condensation water forming in the air channels during the standstill phase of the fan 24, so that it cannot reach the control flaps 31.
  • the condensation water that accumulates there is then evaporated by the resulting draft when the unit is next switched on, so that it is then deposited on the heat exchanger 23. If the condensation water is temporarily frozen, it nevertheless reaches the cold heat exchanger 23 by sublimation.
  • the chambers 39 in the distributor 40 which accommodate the electromotive drives 32 of the flap thermostats, are sealed off with films 51 on the rear side thereof. Likewise, all external parting lines of the plastic molded parts 36 and 37 forming the distributor 30 are sealed with adhesive tapes (not shown).
  • the air duct 27 on the rear of the housing 10 receiving molded part 28 has two outputs 52 and 53 assigned to the control flaps 31, in the vicinity of which a threshold 54 and 55 serving as a drip edge is arranged. With their help, condensation water forming on the wall of the molded part 28 is conducted into pocket-shaped separators 56 and 57 during the idle times of the fan 24 and collected there. At the lower edge of the exits of the air ducts there are aprons 58 which prevent condensation water from running into the gaps at the outlet openings of the air ducts in the rear wall of the housing 10.
