Definitions

  • the present invention relates to an air conditioner.
  • FIGS. 4 to 6 show an example of a conventional air conditioner.
  • FIG. 4 is a front view schematically showing the air conditioner with a portion broken away
  • FIG. 5 is a sectional view taken along the line B-B of FIG. 4
  • FIG. 6 is a sectional view taken along the line C-C of FIG. 4.
  • the interior of a casing 1 of an air conditioner is partitioned into right and left portions by a partition plate 2, and a machine room 3 is formed in one portion, while a heat exchange room 4 is formed in the other portion.
  • an inverter-driven compressor 5, accumulator 8, four-way valve, refrigerant pipes, etc. are arranged, and at the upper part of the machine room 3 is disposed a control box 6.
  • Radiation fins 7 for heat generating equipment such as a power transistor housed in the control box 6 protrude in the heat exchange room 4.
  • an L-shaped heat exchanger 9 In the heat exchange room 4, an L-shaped heat exchanger 9, a pair of fans 10a and 10b, which are arranged vertically, etc. are disposed, and the L-shaped heat exchanger 9 faces an air intake 11 formed in a back face 1a of the casing 1 and an air intake 12 formed in a left side face 1b.
  • the fans 10a and 10b are arranged so as to face air outlets 13a and 13b, respectively, formed in a front panel 1c of the casing 1.
  • the radiation fins 7 are cooled by the fresh air passing through the gaps therebetween.
  • the control box occupies a large space in the machine room 3, so that the space for laying refrigerant pipes becomes insufficient. As a result, there arises a problem in that the machine room 3, in turn, the casing 1 becomes large.
  • US-A-4 736 598 discloses an air conditioner comprising with a casing, the interior of the casing is divided by partition wall into lower chamber facing bottom wall and upper chamber facing top wall. Additionally, the air conditioner has electric parts arranged in the upper chamber and positioned above the heat exchanger chamber, for controlling the operation of the blower and compressor.
  • US-A- 5 081 849 is directed to an air conditioner with an evaporator and a condenser independent from each other.
  • a control box is fixed by its under face to the evaporator.
  • the present invention was made to solve the above problems, and accordingly an object thereof is to provide an air conditioner in which a machine room can be made small.
  • the present invention provides an air conditioner in which the interior of a casing is partitioned by a partition plate into a heat exchange room and a machine room, a heat exchanger and a fan are arranged in said heat exchange room, and a compressor and a control box are arranged in said machine room, the air conditioner being characterized in that said control box is disposed extending into the heat exchange room side beyond the partition plate, and the end thereof is fixed to the top of the heat exchanger via a bracket, and part of said heat exchanger is disposed on the backside of said control box, and part of said heat exchanger extends along a side face of said control box.
  • This configuration provides enough space in the machine room, and the strength and stability of control box is kept by the bracket.
  • the heat in the control box can be released into the heat exchange room through the air vent hole.
  • the heat generated by the heat generating equipment can be dissipated via the radiation fins to the air passing through the heat exchange room.
  • FIGS. 1 to 3 show one embodiment of the present invention.
  • FIG. 1 is a front sectional view schematically showing an air conditioner
  • FIG. 2 is a sectional view taken along the line A-A of FIG. 1
  • FIG. 3 is a perspective view showing a portion near a bracket of the air conditioner.
  • a control box 20 which is short vertically and long sideway, is arranged horizontally on both sides of a partition plate 2.
  • This control box 20 contains a power transistor 22, control board 23, capacitors 24, and the like. At the right end of the control box 20 is attached a terminal board 26 that hangs down.
  • the left end face of the control box 20 is formed with an air vent hole 25 as shown in FIG. 3.
  • Radiation fins 27 for cooling heat generating equipment such as the power transistor 22 protrude from the lower left end face of the control box 20 and extend downward.
  • control box 20 extends to the heat exchange room 4 side beyond the partition plate 2, a space occupied by the control box 20 in the machine room 3 is reduced. Therefore, the machine room 3, and in turn, the casing 1 can be made small.
  • the left end of the control box 20 is fixed to the top of a heat exchanger 9 via a bracket 21. Thereby, the strength and stability of the control box 20 can be improved, and in the case where plural heat exchangers 9 are arranged in rows, they can be fastened by the bracket 21.
  • fresh air taken in the heat exchange room 4 through an air intake 12 passes through the heat exchanger 9, and then passes between the radiation fins 27, so that these radiation fins can dissipate the heat generated by the heat generating equipment to the outside.
  • the heat generated by the heat generating equipment is dissipated from the control box 20 into the heat exchange room 4 through the air vent hole 25, which can prevent the heat generating equipment from overheating.
