The specific embodiment

Now in detail with reference to the preferred embodiment of the present invention, its example is shown in the drawings.Will be referring to Fig. 3 and the 4 air-conditioner indoor units of explaining according to first preferred embodiment of the invention.Fig. 3 illustrates the perspective view according to the air-conditioner indoor unit of first preferred embodiment of the invention, and Fig. 4 illustrates the cutaway view according to the first preferred embodiment of the invention indoor unit, has shown a kind of example that is installed on the wall.

Referring to Fig. 3 and 4, comprise a main case 100 that forms profile according to the first preferred embodiment of the invention indoor unit, this main case has air-breathing part 111 and discharge portion 115; In the main case 100, be used for heat exchange by the room air of air-breathing part 111 suction and the heat exchanger 150 of working fluid; In the main case 100, be used to force the air blast 160 of room air by air-breathing part 111 and discharge portion 115 circulations; But shift-in/shift out main case, be used to make the exhaust apparatus of discharge portion selectively unlocking; And be fixed on the wall and the installing plate 200 equipped with main case 100.

Main case 100 has a previous section 110 and the aft section 120 that is fitted on the indoor wall.Previous section 110 is communicated with aft section 120, and by space between the two heat exchanger 150 and air blast 160 is set.

For equipped main case 100, have fastening projection 210 at an upper portion thereof and at a lower portion thereof at installing plate 200, and aft section 120 has the fixing hole 123 that is used to insert this projection 210 at its back side.

Be height and have an air-breathing part 111 in its front portion, and be discharge portion 115 at its bottom tool greater than the previous section 110 of the rectangle of thickness.The upper and lower part except suction unit is divided of part 110 front portions has front panel 140 in front, is used for the closed interior space.Front panel 140 can form the front surface of sealing previous section 110, and air-breathing part 110 is formed in the front panel 140.

Aft section 120 is from the rear surface projection of previous section 110, and its height and width are littler than previous section 110.Therefore, when aft section 120 was installed on the wall by installing plate 200, what the user mainly saw was previous section, caused this indoor unit integral body to seem small and exquisite.

Previous section 110 and aft section 120 can make separable each other parts, or make global facility.

Simultaneously, also can have additional air-breathing

part

113 and 121 on part 110 and aft section 120 end faces in front.In this case, at by air-breathing part 111, the room air that the air-breathing part 121 in air-breathing part 113 in top and back sucks, heat exchanger 150 can suitably be bent.In order to guide the suction air-flow, can have the air intake grill 131,133,135 that is fitted on air-breathing part 111,113 and 121 smooth-goingly.

Have cover plate 180 on previous section 110 front surfaces, be used for selectively unlocking/air-breathing part 111 before closing.Cover plate 180 not only provides graceful outward appearance, and prevents that air-breathing part 111 of exotic the past from entering, and plays the effect of disturbing between the air that prevents to suck and discharge.For this reason, the cover plate 180 that is formed and covered whole preceding air-breathing part 111 by plane component has a rotatable lower end that is fitted on the main case 110, so that cover plate 180 181 rotations around the lower end, thereby air-breathing part 111 before the opening and closing.In the case, cover plate 180 separates preceding suction portion 111 and discharge portion 115, and has prevented to suck the interference between air and the exhaust of discharge air.

Certainly, air-breathing part 111 before 180 of cover plates are just opened when air-conditioner is worked.Though cover plate can manual control, preferably cover plate 180 is handled automatically by the drive source such as motor.

Have display part 190 on the cover plate 180, be used to show the duty of air-conditioner.Generally speaking, consider that indoor unit is installed on the wall, the inclination if cover plate 180 faces down, the user that is more convenient for so observes display part 190.

Along with exhaust apparatus rotates the bottom of part 110 in front, exhaust apparatus optionally opens or closes discharge portion 115.For this reason, an exhaust casing 300 is fitted into the bottom of previous section 110 rotationally, makes this exhaust casing can move the outside of main case 100 by discharge portion 115 to, and this exhaust casing has a pivot near discharge portion 115.Exhaust casing 300 has import 301 that enters through heat exchange air and the outlet 303 that communicates with the room.

In exhaust casing 300, have and be used for up-down adjustment through the blade 307 of the emission direction of heat exchange air be used for the shutter 309 of left and right adjusting through the emission direction of heat exchange air.Have air inlet grid 305 in the import 301, be used to make air-flow steady.

Exhaust casing 300 upper periphery places have block 320, are used to limit the rotational angle of exhaust casing 300.Therefore, when exhaust casing 300 forwarded to a certain degree, block 320 was just run into the bottom surface of main case 100, and this moment, exhaust casing 300 just can not change again.

In addition, directly rotate exhaust casing 300 though also can make by the user, preferably the work exhaust casing 300 according to air-conditioner rotates automatically.For this reason, has a drive unit that is used for rotating automatically exhaust casing 300 that is contained in previous section.

Drive unit is the motor 311 that is directly connected in exhaust casing 300 rotating shafts, is used for producing when receiving energy revolving force.

Reference numeral 170 expressions that do not lay down a definition are used to make movement-oriented that steadily circulates in the air main case 100.

Below explanation is according to the operation principle of the indoor unit of first preferred embodiment of the invention.

When starting working, cover plate 180 is 181 rotations around the lower end, and meanwhile, motor 311 is by function, so that exhaust casing 300 rotations, as shown in Figure 5.So preceding air-breathing part 111 is opened by the rotation of cover plate 180, and discharge portion 115 is opened by the rotation of exhaust casing 300.That is, the inner space of main case 100 becomes by import 201 and outlet 203 and is communicated with the room.

Then, when air blast 160 during by energy supply, room air is by preceding air-breathing part 111, the air-breathing part 113 in top, and the air-breathing part 121 in back is inhaled into towards heat exchanger 150 sides by the blowing power of air blast 160.Then, room air passes heat exchanger 150 and carries out heat exchange with working fluid, and flows to exhaust casing 200 by import 201 subsequently.

Then, through the air of heat exchange by blade 207 and shutter 209 guidings and by export 203 be discharged into indoor.Because exhaust casing 200 is extracted downwards from main case 100, so can discharge more equably than of the prior art through the air of heat exchange.In the case, the blind area " A " under the indoor unit of prior art can be reduced to minimum.

In addition, if on wall, have the depression that is used for inserting therein aft section 120, then can make advantage of the present invention the most remarkable.Fig. 6 illustrates the cutaway view according to the indoor unit of first preferred embodiment of the invention, has represented that indoor unit is installed to another example on the wall.
