Definitions

  • the present invention relates to a refrigerator, and more particularly to an improvement of the arrangement constitution of a refrigerant compressor in a machine room and a cooler.
  • a refrigerant compressor (42) of a conventional refrigerator which is a link of the refrigerating cycle, as shown in Figs. 9 and 10, is installed almost at the center of a machine room (44) formed on the lower part of the rear of a refrigerator body (31) in the width direction.
  • a cooler (38) for cold storage and a cooler (39) for freezing for generating cold air for cooling a storage chamber composed of a cold storage space (35) and a freezing space (37) are arranged at the center of the internal upper part of a heat insulating cabinet opposite to the compressor (42).
  • a control and power source board (51) is arranged on the outside surface of a heat insulating wall (33) at the opposite position of the cooler for cold storage (38) on the rear of the heat insulating cabinet (for example, refer to Patent Document 1).
  • a concavity is formed by making one part of the back of the lower part of the refrigerator body hollow, and a machine room (74) is formed in the concavity to store a compressor (72), a cooler (69) is installed inside the refrigerator neighboring the compressor (72), and an electronic control board (81) is arranged on the rear of the cooler (69) via a heat insulating wall (63). Further, as shown in Fig.
  • Patent Document 3 Japanese Patent Disclosure (Kokai) 2003-65658
  • Patent Document 2 Japanese Patent Disclosure (Kokai) 2001-41635
  • Patent Document 3 Japanese Patent Disclosure (Kokai) 2002-130922
  • the refrigerant compressor (42) is positioned almost at the center of the main body in the width direction, so that an air flow-in port (50) into the machine room (44) on the upstream side of a partition board (48) for attaching a cooling fan (49) for heat radiation installed at the side of the compressor becomes narrow, and the heat exchange area between fresh air flowing in from an opening (31b) on the front of the main unit and a flat-shaped condenser (43) arranged on the bottom of the main body becomes extremely small, so that heat radiation efficiency is reduced.
  • Patent Document 2 is intended to increase the space efficiency of the machine room, and similarly to Patent Document 1, the distance between the compressor (72) which is a heat source and the cooler (69) is short, and the control board (81) is arranged on the rear of the cooler (69), so that similarly to Patent Document 1, a thermal loss of the cooler (69) due to heat leakage is caused, and it is difficult to obtain the insulating wall thickness. And even in the constitution of Patent Document 3, it is basically the same in this respect that the cooler and heating element are close to each other, thus the same problem arises.
  • the present invention is developed with the foregoing in view, and is intended to provide a refrigerator which, by changing the position relationship and structure of a cooler, a refrigerant compressor, and control and power source boards, can reduce the thermal loss of the cooler, improve the heat insulation efficiency, and increase the heat radiation efficiency of a machine room and a condenser, and thereby can obtain a power conservation effect.
  • the invention of the refrigerator stated in Claim 1 includes a machine room formed on a lower part of a rear of a main body of the refrigerator; a refrigerant compressor installed offset to one side in the machine room in a width direction; and a cooler for receiving a refrigerant from the refrigerant compressor and cooling an inside of a storage chamber; wherein the cooler is arranged inside the refrigerator via a heat insulating wall of the main body above the refrigerant compressor arranged on one side of the machine room and at a position on an opposite side of the compressor in a width direction; and control and power source boards of the refrigerator are arranged in another wide space of the refrigerant compressor in the machine room in a width direction.

  • the cooler can preserve a sufficient heat insulating distance space from a high-temperature member such as the refrigerant compressor so that the thermal loss thereof is reduced, a predetermined heat insulating wall thickness can be preserved as a heat insulating cabinet and hence heat leakage can be prevented, and the heat radiation efficiency of the machine room and condenser can be increased so as to contribute to a reduction in the power consumption.
  • control and power source boards can be mounted compactly and the heat insulating wall thickness on the rear of the freezing chamber can be reserved.

And the refrigerant from the condenser 13 is supplied to the cooler (8) for cold storage or the cooler (9) for freezing in each storage chamber via a capillary tube which acts as a pressure reducing pipe and evaporates, thereby cools each storage chamber to a predetermined air temperature.
  • a step part (16) projecting on the side of a freezing chamber (7) is formed on the lower part of the rear of the main body, and thereby a space having a predetermined depth and height in the width direction is formed by the step part (16).

  • a primary ground (26a) of the control winding and a power winding (26b) for motor control are not common and are insulated at a part A.
  • Motor control unit (28) is structured so as to detect the 3-phase winding resistance by a 3-shunt resistor and to drive the motor of the refrigerant compressor (12) under the vector control.
  • the aforementioned circuit board is often composed of one board of 200 mm x 300 mm or so, and the switching power source is composed of a non-insulated circuit.
  • the board space is an ineffective volume for the refrigerator, so that it is considered to divide it into two parts and to improve the space efficiency.
  • the circuit boards are divided simply into a high-voltage side board composed of large-scale parts and a low-voltage side board densely mountable, when in the switching power circuit formed on the high-voltage side board with the non-insulated type kept, the control winding of the switching power source circuit and the motor control power source are shared so as to reduce the number of turns, the motor control ground and the ground of the inverter switch unit in the low-voltage side board cannot be connected.
  • the control and power source boards (21a) and (21b) divided into 2 parts as described above are positioned in a container (29) in a truncated pyramid shape shown in Fig. 7 by guide projections.

  • the bottom of the high-voltage side board (21a) with the lower height is installed at the position higher by a length h than the bottom of the board (21b) with the higher height.
  • the effect on the control board stays on a level that the accumulated foreign substances firstly reach the low-voltage side circuit board 21b installed on the lower side and the board (21b) firstly enters an unfunctional state, and the accumulated foreign substances do not reach the high-voltage side board (21a) arranged at a higher position, thus the possibility of reaching a failure impairing the safety such as ignition can be reduced.
  • a high-voltage circuit may be arranged on the low-voltage circuit side board (21b). However, at that time, when the high-voltage circuit is arranged on the upper side of the low-voltage circuit, the same effect as the aforementioned can be produced.
