A heat exchanger for cooling and warming the air sucked from the grill 11 and housed inside the heat exchanger. The heat exchanger includes a heat transfer tube and fins surrounding the heat transfer tube. This heat exchanger is used for a refrigeration cycle such as a compressor or an expansion valve. Refrigerant circulating in a refrigeration cycle flows through the inside of the heat transfer tube to exchange heat and cold with air. Reference numeral 2 denotes a cross-flow fan which is a blower that blows air that is driven by a motor to rotate and sucks air to a wind direction changing device 12. Reference numeral 3 denotes a casing that forms an air passage 4.
Is a left and right vane that constitutes the wind direction changing device 12 and changes the wind direction in the left and right direction, 6 is a vertical flap that constitutes the wind direction changing device 12 and changes the wind direction in the vertical direction, 7 is a panel that forms the main body 10, and 14 is a heat exchanger 1 And a drain pan 22 for holding water droplets generated on the surface of the filter. Reference numeral 8 denotes a vane base fixed by a vane base locking pin 23, 9 denotes a nozzle fixed by a nozzle fixing portion 15, 1
3 and 30 are electrical components, 21 is a grill engaging portion, 24 is a grill engaging portion, 26 is a flap driving shaft, 27 is a hole, 28
Is a slider, and 29 is a left and right vane drive shaft.

In FIG. 1, when the cross flow fan 2 driven by the motor rotates, the indoor air is sucked from the grill 11 attached to the front of the indoor unit main body 10 and the panel 7 on the upper surface, and the filter 22 removes dust and the like. Is done.
The sucked air passes between the plate-like fins of the heat exchanger and exchanges heat between the air and the refrigerant to cool or warm the air. The heat exchanger 1, the blower 2, the air passage 4, and the wind direction changing device 12 form a ventilation circuit by the casing 3, the drain pan 14, and the panel 7 inside the main body 10. The dust and oil in the sucked-in air are removed by the filter 22, but what cannot be removed here is the fin portion of the heat exchanger 10, the blade portion of the cross flow fan 2, the surface portion of the casing 3, and the wind direction changing device 12. It adheres to and adheres to various parts of the ventilation circuit such as the left and right vanes 5 and the surface portion of the upper and lower flaps.

FIG. 2 is an explanatory view of the appearance of the indoor unit main body 10 as viewed from the front, with the grill 11 removed and the filter 22 exposed at the center, and the grill 11 removed at the top. 9 is a nozzle, which forms an outlet of a ventilation circuit,
The structure of the nozzle 9 fitted in the panel 7 as shown by the dotted line and removed from the panel 7 is shown in the lower view. The nozzle is inserted into the air passage 4 on the rear side, is hooked on the drain pan 14, and is pushed upward along the panel 7.
The nozzle 9 is fixed to the panel 7 by fitting the protrusion provided on the panel 9 with a nozzle fixing portion 15 having a concave inside and a convex outside. An electrical component 13 is fixed to the right end of the indoor unit body by an elastic claw as shown by a dotted line. The structure taken out is shown on the right side of FIG. The electrical components house components such as boards and elements to which a microcomputer or the like is attached, and are used for controlling an air conditioner. Although the electrical components have been described as being box-shaped and installed at the side edges of the main body 10,
An electrical component 30 may be provided on the nozzle 9 as shown in the lower view of FIG.

In the structure shown in FIG. 2, the nozzle 9 is provided with upper and lower flaps 6 as wind direction changing devices.
Is removed from the panel 7, the upper flap 6 and the motor for driving the upper and lower flaps are simultaneously removed. When the grill 11, the nozzle 9, and the electrical component 13 are removed from the main body 10, the filter 22 is exposed as shown in the figure. By removing this filter, the heat exchanger is exposed. Therefore, the dirt on the heat exchanger can be removed directly by the brush. A heat exchanger that has been used for a long time has a large amount of dirt on the suction-side surface, and this cleaning can remove most of the dirt. Furthermore, since the parts that are problematic for the cleaning liquid, such as electrical components, are removed alone or together with the nozzle, it is possible to spray the cleaning liquid onto the heat exchanger surface for cleaning. Although the cleaning liquid flows through the ventilation circuit, the inside can be easily cleaned because the nozzle 9 has been removed and the air path 4 has been opened. Furthermore, the nozzle alone can be brushed directly outside the air conditioner. As a result, the front and rear surfaces of the upper and lower flaps can be carefully cleaned of dirt, and oil attached to other parts can be wiped off with a cloth.

FIG. 3 is a partial view for explaining a structure for attaching and detaching the grill 11 from the panel 7. The grill engaging portion 21 of the grill 11 is inserted into and fitted to the grill engaging portion 24 also received on the panel 7. It can rotate. When the grill is turned up to the top, the grill engaging portion 21 can be easily removed from the grill engaging portion 24.

The above description has been given of the structure in which the entire wind direction changing device 12 is collectively attached and detached. Hereinafter, the structure in which each component is detached and the air passage is opened will be described. 4A and 4B are explanatory views of a detaching method for removing the upper and lower flaps 6 from the wind direction changing device. FIG. 4A is a view showing a state in which the grill 11 and the upper and lower flaps 6 are mounted on the panel 7, and the upper and lower flaps 6 are blowout ports. Is a position to close the. FIG. 4B is a drawing of the wind direction changing device 12 including a structure fixed to the upper and lower flaps 6 and the panel 7 supporting the upper and lower flaps. The upper and lower flap drive shafts 26 supported by the frame are driven by a motor to rotate. Then the upper and lower flaps 6 integrated with the shaft
Can rotate to change the wind direction. A hole 27 is fixed to the frame of the wind direction changing device 12, and the hole 28 is provided on a plate-like component of the upper and lower flaps so as to be slidable at two positions at the left end and the center in the figure. FIG. 4 (b) shows that it is inserted by the elastic force of FIG. From this state, as shown in FIG. 4C, the shaft of the central slider is slid rightward from the hole 27 against the elastic force to release the engagement between the hole and the shaft.
Also at the left end, the shaft of the slider is slid to the right from the hole 27 to release the hook from the hole. As a result, the leftward movement of the plate-like member becomes free.
By moving the entire flap plate member to the left as shown in (e), the shaft can be disengaged from the right end engaging portion between the plate member and the frame. It is not necessary to provide a slider at the right end. By removing the second plate-like member by the same operation, the upper and lower flaps 6 can be taken out of the main body 10, and the flaps can be easily cleaned externally, and the dirt on the outlet side can be removed. Further, the airflow path 4 is opened by looking at the wind direction changing device 12 provided at the outlet of the panel 7, and the inside of the air conditioner can be easily cleaned.

The attachment and detachment of the right and left vanes will be described with reference to FIGS. A vane base 8 is provided which is in surface contact with and engages with a frame which is a mounting surface of the wind direction changing device 12 with a drain pan or the like. The vane base 8 is divided into two at the center and both ends. The part is rotatably fastened to the frame by a vane base locking pin. During operation, the vane base 8 is pressed against the depression of the frame by the surface of the vane base 8 due to the elasticity of the vane base. When disassembling, the fitting is removed at the center and the vane base 8 is moved toward both ends. The plurality of plate-like parts of the left and right vanes fixed to the air outlet are removed as two separate blocks at the end side of the outlet. This makes it easier to remove dirt by rubbing the left and right vanes protruding outside the air conditioner with a cloth or the like. In addition, move the left and right vanes to move to the end and open the center of the air passage, so carefully brush the cross flow fan inside the air conditioner with a brush attached to the suction port at the tip of the vacuum cleaner from this center. That is, the cleaning tool can be brought into contact with the entire ventilation circuit. The connecting portion of the left and right vane drive shafts 29 with the drive motor moves to the center side when the vane base 8 rotates around the vane base locking portion, so that the motor and the vane base drive shaft are disengaged and when the reassembly is performed. Will move in the opposite direction and combine.

In the above description, the structure in which the plate-like part is removed from the outlet or moved to open the air path has been described.
Here, a configuration is shown in which the wind direction changing device 12 is collectively removed. The wind direction changing device 12 shown in FIG.
Are mounted via a rotating shaft. Also left and right vanes 5
Are integrally fixed to the frame together with the vane base 8. The front end on the rear side of this frame body is inserted into the fitting portion of the casing 3 or the drain pan 14 forming the air passage 4 and is fixed so as not to move by being cut into the panel 7 by a claw on the entrance side. By removing the claws with a tool or pushing the claws, the wind direction changing device 12 can be collectively attached and detached. As a result, the air passage downstream of the cross flow fan is opened, and the air outlet can easily clean the cross flow fan, the air passage, and the wind direction changing device 12 taken out to the outside. In the case of this structure, a drain pan 1 having a drain water drain function
Since 4 is left on the main body side, it is easy to drain the washing water that has washed the heat exchanger even when cleaning the heat exchanger. Although FIG. 7 shows a case in which a central arm is provided on the panel so as to straddle the air outlet in the figure, such a column should be provided at a position where it does not obstruct the cleaner from plunging into the air passage during cleaning. I just need.

FIG. 2 shows a configuration in which the electrical component 30 composed of a substrate or the like and various sensors such as temperature, humidity, dust, human body and other detection elements are attached to the nozzle. By attaching and installing, if only the processing of the wiring terminal is performed, the cleaning liquid is not applied when cleaning the main body of the heat exchanger or the like after removing the parts. In the structure in which the electric component 13 is not removed unlike FIG. 2, the structure of the casing is completely changed so that the washing water does not leak between the ventilation circuit divided by the casing and the electric component 13. By having a separating structure, sealing, covering with a transparent plate, or surrounding with a rib, adverse effects on insulation and the like can be prevented. On the other hand, when storing electrical components in the nozzle 9 or the wind direction changing device 12, if the substrates are mounted on the surface that comes into contact with the panel or the back surface of the drain pan, it is not visible from the surface, and simple cleaning is performed. There is no adverse effect when doing it.

The refrigerant flowing through the heat exchanger tubes of the heat exchanger is an HFC-based refrigerant such as R410A, R407C, R32.
And lubricating oils for compressors include alkylbenzene oils, polyol ether oils, ester oils, and Teflon (registered trademark) oils. Alternatively, the refrigerant is H
C-based refrigerant, for example, R50, R170, R290, R60
0, R600a, R1150, R1270 and the like, and alkylbenzene-based oil, polyol ether-based oil, ester-based oil, Teflon-based oil and the like are used as compressor lubricating oil. Even in such a case, since the air conditioner can be easily cleaned, it is possible to prevent a decrease in circulating air volume due to an increase in ventilation resistance of a heat exchanger or a cross flow fan due to dust or the like. This can prevent a rise in the pressure of the refrigerant inside the refrigeration cycle during heating. As a result, the problem of unnecessary pressure generation on the piping is eliminated, and a highly reliable apparatus can be obtained. In addition, the ventilation is reduced and the effect on the fan characteristics and the heat transfer of the heat exchanger can be prevented, and the optimal design state in consideration of energy saving can be maintained during operation, so the electricity cost can be kept low and the noise deterioration is also prevented. it can. Furthermore, since clogging of each part and remarkable deterioration of ventilation resistance can be prevented, bypass air from other than the ventilation circuit and 2
Invasion of the next air is eliminated, and adverse effects due to the unexpected air inflow, such as performance degradation and fan exposure, can be prevented.

As described above, in the present invention, the components constituting the air path are easily detached or moved during cleaning of the ventilation circuit and the air path, so that the air path configuration of the heat exchanger of the air conditioner, the cross flow fan, etc. There is an effect that dirt attached to the parts can be easily cleaned. Further, by removing the dirt, the pollutants popping out from the outlet of the indoor unit are drastically reduced. In addition, it is possible to prevent the ventilation resistance from increasing and the air volume from being reduced due to contamination of components and devices constituting the ventilation circuit by simple cleaning, and there is an effect that the operation can always be performed in an energy saving state. In addition, since frequent cleaning can be easily performed, the trouble of professional cleaning can be almost eliminated, and the state of the device having high performance and hassle-free operation can be maintained for a long time. The grill,
Nozzles, electrical components, etc. can be detached by fitting, coupling with nails, screws, etc. as described above, so that assembly and disassembly are simple, maintenance and assemblability are easy, and recyclability is also improved. . In addition, it is possible to assemble and disassemble using a tool such as a simple screwdriver with a screw, but it is also possible to obtain the structure of the above invention only by fitting with an elastic body or engaging with a claw, and anyway, anyone can easily ,
That is, the user using the air conditioner can easily disassemble and clean the air conditioner by detaching it and assemble it afterwards.

Further, since the upper and lower flaps can be easily detached or moved from the air path to clean the upper and lower flaps, dirt on the upper and lower flaps can be directly washed and cleaned, and germs such as mold growing on the flaps can be removed. This has the effect.

Further, since the left and right vanes can be easily detached or operated from the air path to clean the left and right vanes, it is possible to directly remove dirt attached to the left and right vanes, thereby removing mold and other germs growing on the vanes. The source of the odor can be eliminated. In addition, cleaning tools with brushes can be brought close to the cross flow fan, making cleaning work very easy.

As described above, the present invention can directly clean dirt and the like adhered to the nozzle, and the upper and lower flaps, the right and left vanes, and the nozzle and the substrate are integrally detached from the unit body so that the flap can be removed. Anybody can easily clean both the detached unit and the detached unit while the link mechanism and wiring of the vane and the like are connected, and can easily remove mold and the like without impairing the reliability of the apparatus. That is, even when a liquid detergent or the like is sprayed on the heat exchanger when cleaning the air conditioner, the cleaning can be easily performed without hitting the substrate and without removing the heat exchanger.

The refrigerant circulating in the refrigeration cycle is operated under conditions that exhibit the expected capacity of the air conditioner. However, if the air conditioner becomes heavily contaminated, the ventilation performance and heat transfer performance decrease, and the capacity decreases. Can not be demonstrated. In the case of extreme clogging, an air flow other than the ventilation circuit causes an abnormality at various points in the main body, for example, generation of mold from each point or dew on a fan. In addition, a change in characteristics due to fouling causes a pressure or the like exceeding a predetermined operation range of the refrigerant condition, which causes a trouble. In particular, when a refrigerant having a large change in pressure rise, for example, a refrigerant such as HFC or HC, is used, it causes not only an accident but also abnormal noise. Such abnormalities can be prevented beforehand by simple cleaning as in the present invention.
