FIG. 6 is an explanatory diagram of a detaching method of the left and right vanes, and FIG. 7 is an explanatory diagram of a detachment structure of the wind direction changing device. Reference numeral 1 denotes a heat exchanger that is housed inside the indoor unit main body 10 and cools or warms the air sucked from the grill 11, and includes a heat transfer tube and fins surrounding the heat transfer tube. A part of a refrigeration cycle such as a valve is formed, and a refrigerant circulating in the refrigeration cycle flows inside 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 the air which is driven by a motor to rotate and sucks air to a wind direction changing device 12, 3 is a casing forming an air path 4, and 5 is a wind direction changing device 12, which configures a wind direction changing device 12 to change the wind direction in the left-right direction. Left and right vanes to be changed, 6 are upper and lower flaps that constitute a wind direction changing device 12 and change the wind direction in the vertical direction, 7 is a panel that constitutes the main body 10, 14 is a drain pan that holds water droplets generated on the surface of the heat exchanger 1, and 22 is a drain pan. It is a filter. 8 is a vane base fixed by a vane base locking pin 23, 9 is a nozzle fixed by the nozzle fixing part 15, 13 and 30 are electrical components, 21 is a grill engaging part, 24 is a grill locking part, 26 Is a flap drive 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. 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 path 4, and the wind direction changing device 12 form a ventilation circuit by the casing 3, the drain pan 14, the panel 7, and the like 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 portions 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 removed grill 11 at the top. Reference numeral 9 denotes a nozzle, which forms an air outlet of the ventilation circuit, is fitted into the panel 7 as shown by a dotted line, and the structure of the nozzle 9 removed from the panel 7 is shown in the lower view. When the nozzle is inserted into the air passage 4 on the rear side and hooked on the drain pan 14 and pushed upward along the panel 7, the projection provided on the panel 7 and the inside of the nozzle 9 are concave and the outside is convex. The nozzle 9 is fixed to the panel 7 by fitting into the nozzle fixing portion 15. 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 lateral end of the main body 10, the electrical components 30 may be provided in the nozzle 9 as shown in the lower diagram of FIG.

  In the structure shown in FIG. 2, the nozzle 9 is provided with an upper and lower flap 6 as a wind direction changing device. When the nozzle 9 is detached from the panel 7, the upper and lower flap 6 and a motor for driving the upper and lower flap 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, 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, so that most of the dirt can be removed by this cleaning. Further, since the parts which are problematic with respect to 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 passage 4 has been opened. Furthermore, the nozzle alone can be brushed directly outside the air conditioner. As a result, the front and back surfaces of the upper and lower flaps can be carefully cleaned, and the oil adhering 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 the grill engaging portion 24 also received by the panel 7 and can be rotated. It has become. When the grill is turned up to the top, the grill engaging portion 21 can be easily removed from the grill engaging portion 24.

  In the above, the structure in which the entire wind direction changing device 12 is collectively attached and detached has been described. Hereinafter, the structure in which each component is detached to open the air path 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, and 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 rotate to change the wind direction. A hole 27 is fixed to the frame of the wind direction changing device 12, and the hole 27 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 due to the elastic force of FIG. From this state, as shown in FIG. 4 (c), the shaft of the central slider is slid to the right against the elastic force from the hole 27 to release the engagement between the hole and the shaft, and at the left end as shown in FIG. 4 (d). Also, 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 movement of the plate member to the left becomes free, so that the entire plate member of the flap is moved to the left as shown in FIG. 4 (e), and the shaft is moved from the right end engaging portion between the plate member and the frame. You can take it off. 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 outside, 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 engaged 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 fixed to the frame by a vane base locking pin. During operation, the vane base 8 is pressed against the recess of the frame by the surface of the vane base 8 due to the elasticity of the vane base. However, when disassembling, the fitting is removed at the center and the vane base 8 is moved toward both ends. The plurality of plate-shaped parts of the right and left vanes fixed to the air outlet are removed as two separate blocks at the end 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 connection between the left and right vane drive shafts 29 and the drive motor is moved to the center when the vane base 8 rotates about the vane base locking portion, and the motor and the vane base drive shaft are disengaged, and when reassembled. Will move in the opposite direction and combine.

  In the above description, the structure in which the plate-like component is removed from the outlet or moved to open the air path has been described. However, FIG. 7 shows a configuration in which the wind direction changing device 12 is collectively removed. In the wind direction changing device 12 shown in FIG. 7, the upper and lower flaps 6 are attached to a frame via a rotating shaft. The left and right vanes 5 are integrally fixed to the frame together with the vane base 8. The front end of the frame body on the back side is inserted into the fitting portion of the casing 3 or the drain pan 14 that forms the air passage 4, and is fixed so as not to bite into the panel 7 with the 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 be easily and collectively cleaned with 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, the drain pan 14 having the drain water draining function is left on the main body side, so that even when the heat exchanger is washed, it is easy to drain the washing water that has washed the heat exchanger. Although FIG. 7 illustrates the case where the panel is provided with a central arm 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. Just fine.

  FIG. 2 shows a configuration in which the electrical component 30 composed of a substrate or the like and various sensors such as temperature and humidity, or detection elements such as dust and a human body are attached to the nozzle. By doing so, if only the processing of the wiring terminal is performed, the cleaning liquid will not be applied when cleaning the main body of the heat exchanger or the like after removing the parts. Further, unlike FIG. 2, in the structure in which the electric component 13 is not removed, 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 ribs, adverse effects on insulation and the like can be prevented. On the other hand, when electrical components are stored in the nozzle 9 or the wind direction changing device 12, if the substrates are mounted on a surface that comes into contact with the panel or the back surface of the drain pan, they are not visible from the surface, and simple cleaning is performed. There is no adverse effect when doing so.

  The refrigerant flowing through the heat exchanger tubes of the heat exchanger is an HFC-based refrigerant, for example, a refrigerant such as R410A, R407C, or R32, and the lubricating oil for the compressor is an alkylbenzene-based oil, a polyol ether-based oil, an ester-based oil, or Teflon. (R) oil or the like is used. Alternatively, the refrigerant is an HC-based refrigerant such as R50, R170, R290, R600, R600a, R1150, R1270, and the lubricating oil for the compressor is an alkylbenzene-based oil, a polyol ether-based oil, an ester-based oil, Teflon (R ) Based oils are used. Even in such a case, since the air conditioner can be easily cleaned, it is possible to prevent a decrease in the amount of circulating air due to an increase in ventilation resistance of the heat exchanger or the 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 that considers 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 and secondary air from other than the ventilation circuit can be prevented from entering, and adverse effects due to unexpected air inflow, such as performance deterioration and fan dew condensation, can be prevented. Can be prevented.

  As described above, according to the present invention, the components constituting the air passage are easily detached or moved at the time of cleaning the ventilation circuit and the air passage, so that the components adhere to the air passage components such as the heat exchanger of the air conditioner and the cross flow fan. There is an effect that easily cleaned dirt can be easily cleaned. Further, by removing the dirt, the pollutants popping out from the outlet of the indoor unit are drastically reduced. Furthermore, it is possible to prevent an increase in ventilation resistance and a decrease in air volume due to contamination of components and devices constituting the ventilation circuit by a simple cleaning, and there is an effect that operation can always be performed in an energy saving state. Furthermore, 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. Grills, nozzles, electrical components, etc. can be detached by fitting, connecting with nails, screws, etc. as described above, making assembly and disassembly easy, maintenance and assemblability easy, and recyclability is also improved. effective. 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 clean up by disassembly such as attaching and detaching and assembling afterwards.

  In addition, since the upper and lower flaps can be easily attached and 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 the effect that germs such as mold growing on the flaps can be removed. is there.

  Also, to clean the left and right vanes, the left and right vanes can be easily attached or detached or operated from the air path. Therefore, by directly cleaning the dirt on the left and right vanes, it is possible to remove molds and other germs that have grown on the vanes and generate odor. Sources can be eliminated. Also, 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 adhering to the nozzle, and the upper and lower flaps, the left and right vanes, and the nozzle and the substrate are integrally detached from the unit body, so that the flaps and the vanes can be removed. Anyone can easily clean both the detached unit and the detached unit with the link mechanism and the wiring connected, without removing the reliability of the apparatus. That is, even if a liquid detergent or the like is sprayed on the heat exchanger when cleaning the air conditioner, the air conditioner can be easily cleaned without hitting the substrate and without removing the heat exchanger.

  The refrigerant circulating in the refrigeration cycle is operated under conditions that allow the air conditioner to exhibit its intended capacity.However, if the air conditioner becomes heavily contaminated, the ventilation performance and heat transfer performance are reduced, and the capacity can be demonstrated. Gone. 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 and dew of the 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.
