Description
- 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, and 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 amachine room 3 is formed in one portion, while aheat exchange room 4 is formed in the other portion. - In the
machine room 3, an inverter-drivencompressor 5,accumulator 8, four-way valve, refrigerant pipes, etc. are arranged, and at the upper part of themachine room 3 is disposed acontrol box 6. Radiation fins 7 for heat generating equipment such as a power transistor housed in thecontrol box 6 protrude in theheat exchange room 4. - In the
heat exchange room 4, an L-shaped heat exchanger 9, a pair offans 10a and 10b, which are arranged vertically, etc. are disposed, and the L-shaped heat exchanger 9 faces anair intake 11 formed in a back face 1a of the casing 1 and anair intake 12 formed in a left side face 1b. - The
fans 10a and 10b are arranged so as to faceair outlets - When the
fans 10a and 10b are driven bymotors 14a and 14b, respectively, fresh air is taken in theheat exchange room 4 through theair intakes heat exchanger 9, by which the temperature is raised or lowered, and then the air, energized by thefans 10a and 10b, is discharged through theair outlets - At the same time, the
radiation fins 7 are cooled by the fresh air passing through the gaps therebetween. - In the above-described air conditioner, 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 themachine 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.
- To achieve the above object, 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.
- If an air vent hole is provided at the end of the control box on the heat exchange room side, the heat in the control box can be released into the heat exchange room through the air vent hole.
- If radiation fins for cooling heat generating equipment inside the control box are protrusively provided on the lower surface of the control box on the heat exchange room side, the heat generated by the heat generating equipment can be dissipated via the radiation fins to the air passing through the heat exchange room.

- FIG. 1 is a front sectional view schematically showing an air conditioner in accordance with one embodiment of the present invention;
- FIG. 2 is a sectional view taken along the line A-A of FIG. 1;
- FIG. 3 is an enlarged perspective view showing a principal portion of an air conditioner in accordance with one embodiment of the present invention;
- FIG. 4 is a partially broken front view schematically showing a conventional air conditioner;
- FIG. 5 is a sectional view taken along the line B-B of FIG. 4; and
- FIG. 6 is a sectional view taken along the line C-C of FIG. 4.
-
- 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, and FIG. 3 is a perspective view showing a portion near a bracket of the air conditioner.
- As shown in FIGS. 1 and 2, at the upper part of a
machine room 3 and aheat exchange room 4, acontrol box 20, which is short vertically and long sideway, is arranged horizontally on both sides of apartition plate 2. - This
control box 20 contains apower transistor 22,control board 23,capacitors 24, and the like. At the right end of thecontrol box 20 is attached aterminal board 26 that hangs down. - The left end face of the
control box 20 is formed with anair 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 thecontrol box 20 and extend downward. - Since other configuration is similar to the configuration of the conventional air conditioner shown in FIGS. 4 to 6, the same reference numerals are applied to elements of this embodiment which correspond to the elements of the conventional air conditioner, and the explanation thereof is omitted.
- Since the
control box 20 extends to theheat exchange room 4 side beyond thepartition plate 2, a space occupied by thecontrol box 20 in themachine room 3 is reduced. Therefore, themachine 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 aheat exchanger 9 via abracket 21. Thereby, the strength and stability of thecontrol box 20 can be improved, and in the case whereplural heat exchangers 9 are arranged in rows, they can be fastened by thebracket 21. - During the operation of the air conditioner, fresh air taken in the
heat exchange room 4 through anair intake 12 passes through theheat 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. - Also, the heat generated by the heat generating equipment is dissipated from the
control box 20 into theheat exchange room 4 through theair vent hole 25, which can prevent the heat generating equipment from overheating. - Further, if an air vent hole is provided at the end of the control box on the heat exchange room side, the heat in the control box can be released into the heat exchange room through the air vent hole.
