Description

  The present invention relates to a refrigerator.

  In general, a refrigerator has a refrigerator room, a vegetable room, and a freezer room in order from the top, and recently, an ice making room and a switching room are newly added to the product. The figure is shown in FIG.

  FIG. 9 is a front view of the refrigerator. The ice making chamber 101 and the switching chamber 103 are independent drawer types and are arranged in parallel on the left and right. From the viewpoint of ease of use, the location is located above the vegetable compartment 107 under the refrigerator compartment 105 and in order from the top is the refrigerator compartment 105, the ice making room 101 and the switching room 103 arranged in parallel to the left and right, the vegetable compartment 107, and the freezer compartment 109. It has a layout structure.

  Looking at the layout structure of the refrigerator compartment, the vegetable compartment 107 is directly sandwiched between the ice making room 101, the switching room 103, and the freezing room 109 arranged in parallel from above and below.

  Of the ice making chamber 101 and the switching chamber 103, the ice making chamber 101 is a place where ice is produced, and the inside of the cabinet has a minus freezing temperature. The switching chamber 103 can be widely switched from a plus temperature to a minus freezing temperature corresponding to foodstuffs, and the vegetable compartment 107 is sandwiched from above and below by a minus freezing temperature zone with a lower freezing chamber 109. It becomes a sandwich structure. For this reason, it has a problem that the inside of the vegetable compartment 107 reaches a specified temperature or less.

  The vegetable room 107 is desirably not lower than a specified temperature because of the property of storing vegetables and the like, and is generally warmed by a temperature compensation heater, but it is not desirable in terms of running cost because it consumes electric power.

  Then, in this invention, it aims at providing the refrigerator which succeeded in suppressing the consumption of electric power small.

  In order to achieve the above object, in the present invention, the refrigerator main body, the refrigerant discharged from the compressor passes through the condenser, the expansion device, the evaporator, and returns to the compressor again; Two food rooms, a vegetable room directly sandwiched between the food room and the food room, and a temperature compensation heater that turns on and warms the vegetable room when the vegetable room falls below a specified temperature. The vegetable compartment is always warmed by heat radiation from a refrigeration cycle pipe that communicates with the condenser separately from the temperature compensation heater and forms a part of the condenser.

  According to the present invention, the vegetable compartment can be always warmed by heat radiation by the refrigeration cycle pipe which is a part of the condenser. At this time, since heat radiation by the refrigeration cycle pipe is used, there is no cost. On the other hand, the vegetable room is unlikely to become below the specified temperature due to heat radiation, and the frequency of use of the temperature compensation heater can be greatly suppressed. As a result, the amount of heater power used with the heater can be reduced, which is very preferable in terms of running cost.

  In the present invention, first, the refrigeration cycle pipe is warmed from the back by placing it on the back of the vegetable compartment.

  Secondly, the refrigeration cycle pipe is placed on the side of the vegetable compartment to warm it from the side.

  Third, the refrigeration cycle pipe can be easily extended with respect to the back or side of the vegetable compartment by using a refrigeration cycle heat radiating pipe that is part of a condenser disposed in a part of the refrigerator body. Allow placement.

  4thly, by making the said refrigerating cycle pipe into a dew-proof pipe for the defrosting in a store | warehouse | chamber which becomes a part of the condenser arrange | positioned along the opening periphery of a storehouse | chamber, it is easy with respect to the side part of a vegetable compartment Allow extended placement.

  Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 8.

  FIG. 1 is a schematic sectional side view of a refrigerator according to the present invention, and FIG. 2 is a schematic front view of the refrigerator.

  The refrigerator main body 1 has the refrigerator compartment 3 arrange | positioned in an order from the top, the ice making room 5 and the switch room 7 arrange | positioned in parallel, the vegetable compartment 9, and the freezer compartment 11, respectively. The refrigerator compartment 3 is an independent chamber, and the door 3a is a hinge type that opens and closes with the hinge 15 as a fulcrum.

  In addition to the ice making chamber 5 and the switching chamber 7 arranged in parallel, the doors 3a, 5a, 9a, 11a of the vegetable chamber 9 and the freezing chamber 11 are each a drawer type having independent interiors. The vegetable room 9 is set at a relatively high temperature as compared with the freezing room 11, the ice making room 5, and the switching room 7 where vegetables and the like are stored.

  Of the ice making chamber 5 and the switching chamber 7, the ice making chamber 5 is made where ice is produced, and the inside is controlled so as to have a negative freezing temperature. The switching chamber 7 can be switched and controlled from a plus temperature to a minus freezing temperature corresponding to the food.

  The freezer compartment 11 stores frozen food, and the inside of the refrigerator is managed to have a negative freezing temperature, and the vegetable compartment 9 described above has a layout structure sandwiched from above and below by a negative freezing temperature zone. The vegetable compartment 9 is heated by the heat radiation of the refrigeration cycle pipe 21 which is a part of the condenser 19 constituting the refrigeration cycle in addition to the temperature compensation heater 17.

  The temperature compensation heater 17 is disposed across the ceiling, bottom, and back of the vegetable compartment 9 and is turned on when the internal temperature sensor S installed in the vegetable compartment 9 detects a temperature below a specified temperature. The interior is warmed.

  Therefore, the temperature compensating heater 17 is placed in a standby state unless the inside of the refrigerator is below the specified temperature.

  On the other hand, as shown in FIGS. 4 and 5, the refrigeration cycle pipe 21 that warms the vegetable compartment communicates with the condenser 19 and is a part of the condenser 19 for refrigeration cycle heat radiation 23 and a defrosting prevention chamber. A dew pipe 25 is provided.

  In the condenser 19, the compressor 27, the expansion device 29, and the evaporator 31 constitute a refrigeration cycle. The evaporator 31 is disposed in a cooling passage 33 (partially shown) provided in the rear part of the refrigerator main body 1, and the cold air heat-exchanged by the evaporator 31 is sent into each cabinet by a fan (not shown). As a result, the interior is cooled.

  The compressor 27, the condenser 19, and the expansion device 29 are arranged in a machine room 35 provided at the lower rear of the refrigerator compartment body 1.

  The heat radiating pipe 23 is an existing heat radiating pipe for refrigeration cycle heat radiating, and since the refrigerant discharged from the compressor 27 flows, high-temperature and high-pressure refrigerant flows. Since the arrangement place is provided along the outer box panel 13b of the refrigerator main body 1 constituted by the inner box panel 13a and the outer box panel 13b, a part of the place is shown in FIG. 3 and FIG. It extends to the back part 23a (inside the dotted line). Alternatively, as shown in FIG. 6 and FIG. 7, the heat radiating pipe 23 may be extended to the side of the vegetable compartment 9 so as to extend 23 a (inside the dotted line). In this case, it is possible to have a structure arranged on both sides as shown.

  Thereby, since the existing heat radiating pipe 23 is used, arrangement | positioning work becomes easy. In this case, a means for combining the back portion and the side portion may be used.

  The dew-proof pipe 25 is an existing dew-proof pipe for defrosting the inside of the cabinet. The dew-proof pipe 25 is located downstream of the condenser 19 and flows a medium / low-pressure refrigerant. The arrangement place is provided as means extending from a place along the peripheral edge of the opening to the side of the vegetable compartment 9 as shown in FIG. In this case, the structure may be arranged on both sides as shown.

  Thereby, since the existing dew-proof pipe 25 is used, the arrangement work is facilitated. In this case, since both are means for utilizing the heat radiation of the heat radiating pipe 23 and the dew proof pipe 25, there is no running cost as with a heater.

  In addition, although the heat radiating pipe 23 and the dew prevention pipe 25 which are extended and arranged to the back part and side part of the vegetable compartment 9 are provided along the inner side of the outer box panel 13a, you may provide it in the outer side of the outer side panel 13b. In this case, it is desirable to use a cosmetic cover for blindfolding in terms of appearance.

  According to the refrigerator configured as described above, the vegetable compartment 9 during operation of the refrigerator is warmed by heat radiation by the heat radiating pipe 23 or the dew proof pipe 25 serving as the refrigeration cycle pipe 21. At this time, there is no cost for using heat radiation by the pipe. On the other hand, the inside of the vegetable compartment 9 is unlikely to become below the specified temperature due to heat radiation, and the frequency of use of the temperature compensation heater 17 is greatly suppressed. As a result, the amount of heater power used with the heater can be reduced, which is very preferable in terms of running cost.
