  According to claim 2, the indoor air quality can be improved, such as efficiently removing allergens in the intake air.

  Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals in the drawings indicate the same or equivalent.

  First, the whole structure of an air conditioner is demonstrated using FIG. 1, FIG. 2, FIG. 3, FIG. FIG. 1 is a configuration diagram of an air conditioner according to an embodiment. FIG. 2 is a side sectional view of the indoor unit of the air conditioner. FIG. 3 is a side sectional view of the indoor unit during the cooling / dehumidifying operation. FIG. 5 is a perspective view showing a front panel flip-up state of the indoor unit.

  The air conditioner 1 connects the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 to air-condition the room. In the indoor unit 2, an indoor heat exchanger 33 is placed at the center of the housing base 21, and a cross-flow fan type blower fan 311 having a length substantially equal to the width of the heat exchanger 33 is disposed on the downstream side of the heat exchanger 33. Then, a dew tray 35 and the like are attached, these are covered with a decorative frame 23, and a front panel 25 is attached to the front surface of the decorative frame 23. The decorative frame 23 is provided with an air inlet 27 for sucking in indoor air and an air outlet 29 for blowing air with adjusted temperature and humidity.

  The indoor heat exchanger 33 is installed to protrude upward and straddle the blower fan 311 so as to make the heat transfer area as wide as possible by effectively using the space of the indoor unit 2. The blower fan 311 causes the blown airflow to flow through a blowout air passage 290 having a width substantially equal to the length of the blower fan 311, and the blown airflow is deflected in the left-right direction of the airflow by the left and right wind direction plates 295 arranged in the middle of the blowout air passage 290 Further, the vertical direction of the airflow is deflected by the vertical airflow direction plate 291 disposed at the air outlet 29 and is blown into the room.

  When the blower fan 311 rotates, room air is blown from the air blowout port 29 through the indoor heat exchanger 33 and the blower fan 311 from the air suction port 27 provided in the indoor unit 2.

  Basic internal structures such as a blower fan 311, a filter 231, an indoor heat exchanger 33, a dew tray 35, an up / down air direction plate 291, and a left / right air direction plate 295 are attached to the housing base 21. And these basic internal structures are included in the housing | casing 20 which consists of the housing | casing base 21, the decorative frame 23, and the front panel 25, and comprise the indoor unit 2. FIG.

  Further, on the lower side of the front panel 25, as shown in FIG. 5, a display unit 397 for displaying an operation status and a light receiving unit 396 for receiving an infrared operation signal from a separate remote controller 5 are arranged. .

  An air outlet 29 formed on the lower surface of the decorative frame 23 is disposed adjacent to the divided portion with the front panel 25 and communicates with the rear outlet air passage 290. The up-and-down wind direction plate 291 is configured to have a large curved surface that is substantially concealed from the blowing air passage 290 and is continuous with the bottom surface of the indoor unit 2 in the closed state. These up-and-down wind direction plates 291 are pivoted at a required angle when the air conditioner 1 is operated by a drive motor in response to an instruction from the remote controller 5 with pivot shafts provided at both ends as fulcrums. 29 is opened as shown in FIG. 3 and held in that state. When the operation of the air conditioner 1 is stopped, the up-and-down air direction plates 291 are controlled so as to close the air outlet 29.

  The left and right wind direction plates 295 are rotated by a drive motor with a rotation shaft provided at the lower end portion as a fulcrum, and are rotated in accordance with an instruction from the remote controller 5 and held in that state. As a result, the blown air is blown out in the left and right desired directions. By instructing from the remote controller 5, the up and down wind direction plate 291 and the left and right wind direction plate 295 can be periodically oscillated during the operation of the air conditioner 1, and the blown air can be periodically sent over a wide range in the room.

  The indoor unit 2 includes a control board in an internal electrical component box, and a microcomputer is provided on the control board. The microcomputer receives signals from various sensors such as an indoor temperature sensor and an indoor humidity sensor, and receives an operation signal from the remote controller 5 via the light receiving unit 396. Based on these signals, the microcomputer controls the indoor blower fan 311, the up / down wind direction plate drive motor, the left / right wind direction plate drive motor, etc., and controls the communication with the outdoor unit 6, and controls the indoor unit 2 as a whole. To do.

  The filter 231 is for removing dust contained in the sucked room air, and is disposed at the air suction port. The dew tray 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33, and is provided to receive condensed water generated in the indoor heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water received and collected is discharged to the outside through the drain pipe 37.

  Next, a functional member storage structure added to improve the air quality of the present embodiment will be described with reference to FIGS. FIG. 4 is a side sectional view showing a state in which the front panel of the indoor unit is flipped up.

  As described above, recent air conditioners are expected to improve indoor air quality in addition to adjusting indoor temperature and humidity. In order to improve air quality, there are various functions such as air cleaning function to remove allergens such as pollen and house dust, deodorization, negative ion addition, addition of charged fine water droplets, humidification, etc. An air cleaning filter that can collect dust with a diameter of 10 μm or more with a high efficiency close to 99.9% and also has a deodorizing function will be described as an example.

  The air cleaning filter 331 is a non-woven fabric containing a deodorizing agent, folded in a pleat shape and charged with static electricity, and has an air cleaning function. This air purifying filter 331 is made to face the air path between the lower part on the upstream side of the heat exchanger 33 and the filter 231 provided in the suction port 27. Specifically, a support frame 333c that allows ventilation is formed in the closing member 333 that constitutes the air passage, and the air purifying filter 331 is suspended and stored in the support frame 333c.

  Thereby, when the air conditioner is operated, the air flow caused by the blower fan 311 partially passes through the air cleaning filter 331 as shown by the arrow in FIG. While removing allergens such as house dust, it captures odor components and develops deodorizing action. Since the air cleaning filter 331 accumulates dust such as pollen and house dust due to long-term use, it is necessary to perform cleaning such as washing with water about once every two to three years.

  For this reason, the opening 333a for attaching / detaching the air cleaning filter 331 is provided at an appropriate position of the closing member 333 so that the air cleaning filter 331 stored in the storage portion 333b of the air cleaning filter 331 can be attached / detached from the front panel 25 side. A lid member 335 is detachably attached to the opening 333a for attachment / detachment. Further, as shown in FIG. 4, the front panel 25 is pivotally supported at the upper part by the upper front part of the decorative frame 23, and the lower part can be freely opened and closed so that the closing member 333 springs up by utilizing the spring property of the material. Is done. By doing in this way, at the time of cleaning of the air purifying filter 331, the air purifying filter 331 can be easily attached or detached without using a tool.

  As described above, even if the lid member 333 and the front panel 25 are both configured to be detachable, the one lid member 335 has a small size, and the detachable partner is only the closing member 333 and is in contact with the closing member 333. The other front panel 25 has a large size and is in close contact with the main body of the indoor unit 2, while it can improve the adhesion by forming the part on the same plane and reduce air leakage. There are a wide variety of other parts, and the shape tends to be complicated to give an aesthetic appearance, and it is impossible to reduce air leakage by bringing them into close contact with each other with a small force to make them detachable.

  In general, when a blower is operated, an air flow is generated between the suction side and the suction port of the blower, a pressure difference is generated by this air flow, and ambient air is sucked from a slight gap between the blower and the suction port, and the suction port is Air that does not pass is sucked into the blower and blown out. In the air conditioner, the air that does not pass through the suction port is air that has not passed through the filter and contains a large amount of dust, so that it adheres to the heat exchanger and the ventilation path of the housing and causes contamination. In addition, since the air that does not pass through the suction port is not subjected to the action of purifying the room air with the filter of the air conditioner, the action of purifying the room air is diminished. For this reason, it is desirable to eliminate as much as possible the suction of air that does not pass through the suction port, but it is difficult to eradicate it from the above-mentioned manufacturing restrictions.

  On the other hand, the maintenance work after the air conditioner is installed is easy, and maintaining the initial performance plays an important role in reducing the burden on the environment. There is a strong demand for freedom. For this reason, it is possible to perform internal maintenance and inspection work by flipping up without using a tool on the front panel. In this case, since the front panel having a large area is easily attached and detached, the front panel and the main body side cannot be brought into close contact with each other, and a gap is formed between the main body side. Air that does not pass through the suction port is sucked from this gap, and promotes dirt inside.

  In the present invention, the closing member 333 is provided between the front panel 25 and the heat exchanger 33 in order to meet the two contradicting demands of the above-described simplicity during maintenance work and adhesion that suppresses air leakage. The closing member 333 is locked in close contact with the dew receiving tray 35 at the lower part and the guide frame 234 of the cleaning mechanism of the filter 231 described later, and almost completely blocks leaked air entering the heat exchanger 33 from the front. . As a result, the amount of leaked air that flows directly to the heat exchanger 33 without passing through the filter 231 is reduced, dirt in the heat exchanger 33 and the indoor unit 2 is reduced, and the air purification action in the filter 231 is not diminished.

  At this time, in order to detachably lock the front panel 25 and the lid member 335, holes or the like are provided in the closing member 333. The area of these holes is a gap generated between the front panel and the main body of the indoor unit 2. The holes are much smaller than the above, and the engaging portions of the front panel 25 and the lid member 335 are fitted into these holes, so that the area of the gap is further reduced, so that air leakage from these holes is very small. . However, it is desirable to minimize the area of these holes and should not unnecessarily make holes larger than necessary.

  A series of attaching / detaching operations of the air purifying filter will be described with reference to FIGS. FIG. 6 is an explanatory view of attaching and detaching the lid member of the indoor unit. FIG. 7 is an explanatory diagram of an air cleaning filter replacement operation of the indoor unit, (b) is a perspective view of a dust collection box of the cleaning mechanism, and (c) is a perspective view of a cleaning brush of the cleaning mechanism.

  When the air purifying filter 331 is attached, first, the front panel 25 is opened as shown in FIG. 5, and the lid member 335 that has appeared is pulled forward with the knob of the lid member 335, and the lid member 335 is removed as shown in FIG. The air purification filter 331 is inserted from the opening 333a as shown in FIG. 7, and the air purification filter 331 is attached to the storage portion 333b. When cleaning this, the air purification filter 331 is removed in the reverse order, washed with water and dried, and then returned to the storage portion 333b. As described above, the cleaning operation of the air purification filter 331 can be performed without using a tool, and the frequency thereof is about once every two to three years, so that it is not a burden on the user.

  Next, the filter cleaning means will be described with reference to FIG. FIG. 8 is a perspective view of the filter cleaning mechanism of the indoor unit.

  In the embodiment, a planar filter 231 is provided at the air suction port 27. The filter 231 is engaged with the guide frame 234, and the guide frame 234 includes a rear and front rails, and a propulsion shaft that is arranged in parallel with the rails on the front rail.

  The propulsion shaft has a polygonal cross section, is pivotally supported by a bearing provided in the guide frame 234, and is connected to a moving motor fixed to the guide frame 234 via a gear attached to one end passing through the bearing on one side. . A screw and a carriage are loosely mounted on the propulsion shaft, and the screw meshes with a rack provided on the guide frame 234 and parallel to the propulsion shaft.

  A brush support frame 262 is suspended across the filter 231 between the carriage and the rail, and a cleaning brush 267 that sweeps and cleans the filter 231 is attached to the brush support frame 262.

  Thus, by rotating the moving motor, the propulsion shaft and the screw rotate, and the screw moves in the left-right direction along the rack according to the rotation direction of the moving motor, thereby moving the carriage. As a result, the cleaning brush 267 moves so as to sweep while being in sliding contact with the filter 231, the dust on the filter 231 is swept by the cleaning brush 267, and moved to the dust removing brush 270 on the left side of the guide frame 234.

  The bristles of the cleaning brush 267 use soft bristles, and when the cleaning brush 267 is pressed against the surface of the filter 231 and moved, the filter 231 can be secured even after being deformed by the pressing of the cleaning brush 267. It is good to select according to the rigidity of the filter 231 so that it can do. Here, “overlapping” means the length from the filter surface to the tip of the hair when it is assumed that the hair of the cleaning brush 267 is straight without deformation.

  Thus, since soft hair is used for the cleaning brush 267, the force for deforming the filter 231 is small, and it is only necessary to sweep the filter 231 from one side, and the dust on the filter 231 can be swept without supporting the filter 231 from the back side. Can be taken. For this reason, a drive mechanism for sweeping the filter 231 with the cleaning brush 267 may be provided only on one side of the filter 231, and the drive mechanism is greatly simplified.

  Next, the configuration and operation of the cleaning mechanism will be described with reference to FIG. FIG. 9 is a detailed view of the sweeping operation of the collected dust of the cleaning mechanism.

  On the right side of the filter 231 is a standby unit 238 on which the cleaning brush 267 waits when the cleaning operation is not performed. The standby portion 238 is provided with a recess F234f that is recessed from the surface of the filter as shown in F portion of FIG. 9, and a cleaning brush 267 that is bent as shown in E portion of FIG. As shown in part F of FIG. 9, it is opened and restored to a straight state.

  Thereby, while the cleaning brush 267 is on standby, the force for bending the cleaning brush 267 does not work, and the cleaning brush 267 is not bent. Further, the deformation of the hair ends caused by twisting at the mesh of the filter 231 when moving on the filter 231 is restored and arranged.

  For this reason, the cleaning brush 267 is in sliding contact with the filter 231 in a predetermined state each time the cleaning operation is performed, the cleaning operation is stabilized, and the desired cleaning performance can be exhibited. Further, since the tip of the cleaning brush 267 is opened in the standby unit 238, the tip of the cleaning brush 267 starts reversing as compared with the case where the tip of the cleaning brush 267 is bent without the recess F234f. Since it is not disturbed and an unnecessary force is not applied, an extra load is not applied to the drive mechanism of the cleaning brush 267, and the reliability of the drive mechanism is improved.

  Further, since unnecessary force is not applied to the hair tips when the cleaning brush 267 is reversed, the tip of the hair is hardly deteriorated, and the interval for replacing the cleaning brush 267 can be increased. A recess C234c is provided between the filter 231 and the removal brush 271. The depth of the recess C234c is such that the top surface of the removal brush surface 271a is substantially equal to the surface of the filter 231 at the rotation position of the removal brush 271 where the removal brush surface 271a is exposed to the maximum at the cleaning brush 267 side. The tip of the cleaning brush 267 is set to reach the bottom of the recess C234c.

  By doing so, the cleaning brush 267 can be slidably contacted with the removal brush 271 without deforming the cleaning brush 267 more than when the filter 231 is swept, and the cleaning brush 271 is not excessively deformed. Deterioration of the cleaning brush 271 can be suppressed. Further, the removal brush 271 can be exposed to the cleaning brush 267 side by the depth of the recess C234c, the area of the removal brush surface 271a can be increased, and stable dust 236 removal performance can be exhibited. .

  When the cleaning operation is performed, the cleaning brush 267 that has been waiting as shown in the F part of FIG. 9 is moved to the standby part 238 as shown in the D part of FIG. 9 by operating the drive mechanism and sweeping the filter 231. . At this time, the bristles of the cleaning brush 267 ride on the surface of the filter 231 protruding through the slope F233f from the open state of the recess F234f while gradually bending and deforming the bristles, and make firm sliding contact with the filter 231.

  The cleaning brush 267 sweeps the filter 231 and moves the dust 236 while moving in the direction of the dust removing brush 270. The cleaning brush 267 that has finished sweeping the filter 231 reaches the position of the portion C in FIG. 9 together with the dust 236 that has been swept away, the hair tip is slightly deformed in the recess C234c, reaches the dust removal brush 270, and the removal brush The dust 236 is transferred to the removal brush 271 while effectively slidingly contacting the surface 271a.

  268 is a brush presser, which is provided on one or both sides of the brush to give an appropriate elasticity to the tip of the brush during the cleaning operation, to maintain good dust sweepability, and to give excessive deformation to the base of the brush. The brush does not break from the root. When the brush presser is provided on one side, it is preferably provided on the side where the brush tip is deformed during the cleaning operation for the above-mentioned reason. Further, when provided on both sides, the deformation of the brush tip becomes almost the same during the cleaning operation and the return operation, and it is possible to prevent the brush from being unevenly wrinkled.

  The brush support frame 262 stops when the lever projection 269 gets over the rotation lever 271c, but this portion is a recess A234a that is recessed from the above-described recess C234c. In the recess A234a, the tip of the cleaning brush 267 is opened like the recess F234f of the standby portion 238 described above, and is inverted to start moving toward the filter 231. Accordingly, while the cleaning brush 267 is stopped, the cleaning brush 267 is restored from the bent state to the straight state. Further, the deformation of the hair ends caused by twisting at the mesh of the filter 231 when moving on the filter 231 is restored and arranged.

  Furthermore, since the bristles are released while the cleaning brush 267 is stopped, the hairs when the cleaning bristles 267 start reversal compared to the case where the recess A234a is not present and the bristles remain bent. Since the tip is not disturbed and unnecessary force is not applied, the drive mechanism of the cleaning brush 267 is not subjected to an excessive load, and the reliability of the drive mechanism is improved. Further, since unnecessary force is not applied to the hair tips when the cleaning brush 267 is reversed, the tip of the hair is hardly deteriorated, and the interval for replacing the cleaning brush 267 can be increased. When the cleaning brush 267 moves in the reverse direction, the tip of the cleaning brush 267 runs from the open state of the recess A234a while gradually bending and deforming the tip of the hair on the surface of the filter 231 protruding through the slopes A233a and C233c. The filter 231 is in sliding contact.

  Next, the cleaning brush 267 moves while sliding in contact with the filter 231 by deforming the hair tip in the direction opposite to that at the time of cleaning, and moves toward the standby unit 238. In this way, the cleaning brush 267 is reciprocated so that the bending direction of the hair tip is reversed. Therefore, compared with the case where the cleaning brush 267 is slidably contacted only in one direction, the bending wrinkles are less likely to occur, and the force for pressing the filter 231 is kept constant each time. can do. For this reason, the ability to clean the filter 231 can be maintained for a long time.

  The dust 236 scraped from the cleaning brush 267 by the removal brush 271 is pushed into the brush holder 276 when the cleaning brush 267 returns and falls into the dust collection box 284. The dust accumulated in the dust collection box 284 is opened once every few years, the front panel 25 is opened, the knob portion 284c of the dust collection box 284 is held, the dust collection box 284 is pulled out from the removed dust discharge port 281b, and collected. Dust inside the dust box 284 is discarded and cleaned.

  As described above, the air inlet 27 for indoor air is provided only on the upper surface, and the automatic cleaning mechanism for the filter 231 provided in the air inlet 27 is provided, thereby cleaning the filter 231 indispensable for maintaining the performance of the air conditioner. This can be done without bothering the user. Moreover, the air leakage from the front panel 25 side can be suppressed by the closing member 333, dirt in the heat exchanger 33 and the indoor unit 2 can be reduced, and the expected performance of the air conditioner can be maintained for a long time. Furthermore, the air purification filter 331 can be attached and detached without using a tool, and the indoor air quality can be improved. Furthermore, since the filter 231 is provided only on the upper surface, the size of the filter can be reduced as compared with the case where the filter 231 is provided on the upper surface and the front surface.

  As described above, the air conditioner of the embodiment includes the suction port, the filter, the heat exchanger, the cross-flow type blower, and the blowout port, and the suction port is provided only on the upper surface, and the automatic cleaning mechanism of the filter And a front panel that can be flipped up and a closing member provided between the heat exchangers projecting upward, and a storage portion for the functional member provided on the heat exchanger side of the closing member. The closing member is provided with an opening for attaching and detaching the functional member and a lid member for closing the opening.

  Thereby, a part of the intake air passes through the air purification filter, allergens drifting in the airflow are removed, the room is gradually cleaned, and a comfortable space is formed. At this time, since the closing member is provided inside the front panel that can be flipped up, the intake air is sucked only from the suction port on the top surface, and the air that does not pass through the suction port from the gap between the front panel that can be flipped up and the main body Is not sucked in and does not promote internal dirt. Further, the purifying action of the indoor air that the air conditioner has is not diminished. In addition, since a projecting heat exchanger is used above, it becomes a flow path of indoor air sucked between the closing member provided inside the front panel that can be flipped up and the front part of the heat exchanger. An air purifying filter can be exposed to the flowing airflow, and an air purifying action is induced. In addition, the front panel that can be flipped up is used to facilitate the maintenance work of the air conditioner, and the cleaning of the filter, which is the biggest problem in the maintenance work of the air conditioner, is automated, thereby reducing the environmental burden. Can be reduced. Further, since the front panel does not open forward during the operation of the air conditioner, the interior of the indoor unit is not exposed to the eyes of the user, and the indoor atmosphere is not disturbed and the aesthetics are maintained.

  Therefore, it is possible to provide an air conditioner that does not disturb the indoor atmosphere during operation, improves the degree of purification of the blown air, and facilitates maintenance.

  In the air conditioner according to the embodiment, the storage unit stores the functional member so that the functional member partially blocks the airflow flowing into the front portion of the heat exchanger.

  Thereby, the air flow partially blocked by the functional member generates a pressure difference before and after the functional member, and a part of the air flow also flows through the functional member due to the pressure difference. The airflow that has flowed through the functional member is removed from the allergen contained in the airflow or added with a fragrance, so that the air quality is improved and the air is blown into the room. Thus, since the air quality of the airflow flowing through the functional member is improved, the indoor air quality is gradually improved, and the indoor environment becomes comfortable.

  For this reason, the air conditioner which can aim at the improvement of indoor air quality, such as removing the allergen in intake air efficiently, can be provided.

  As described above, according to the air conditioner of claim 1, the air conditioner includes a suction port, a filter, a heat exchanger, a cross-flow type blower, and a blowout port, and the suction port is provided only on the upper surface. A function provided on the heat exchanger side of the closing member, having an automatic cleaning mechanism for the filter, a front panel that can be flipped up, and a closing member provided between the heat exchangers protruding upward. The storage part of the member is arranged so as to face the air flow generated by the blower, and the opening for attaching / detaching the functional member and the lid member for closing the opening are provided on the closing member.

  Thereby, a part of the intake air passes through the air purification filter, allergens drifting in the airflow are removed, the room is gradually cleaned, and a comfortable space is formed. At this time, since the closing member is provided inside the front panel that can be flipped up, the intake air is sucked only from the suction port on the top surface, and the air that does not pass through the suction port from the gap between the front panel that can be flipped up and the main body Is not sucked in and does not promote internal dirt. Further, the purifying action of the indoor air that the air conditioner has is not diminished. In addition, since a projecting heat exchanger is used above, it becomes a flow path of indoor air sucked between the closing member provided inside the front panel that can be flipped up and the front part of the heat exchanger. An air purifying filter can be exposed to the flowing airflow, and an air purifying action is induced. In addition, the front panel that can be flipped up is used to facilitate the maintenance work of the air conditioner, and the cleaning of the filter, which is the biggest problem in the maintenance work of the air conditioner, is automated, thereby reducing the environmental burden. Can be reduced. Further, since the front panel does not open forward during the operation of the air conditioner, the interior of the indoor unit is not exposed to the eyes of the user, and the indoor atmosphere is not disturbed and the aesthetics are maintained.

  Therefore, it is possible to obtain an air conditioner that does not disturb the indoor atmosphere during operation, improves the degree of purification of the blown air, and facilitates maintenance.

  According to the air conditioner of the second aspect, the storage unit stores the functional member such that the functional member partially blocks the airflow flowing into the front portion of the heat exchanger.

  Thereby, the air flow partially blocked by the functional member generates a pressure difference before and after the functional member, and a part of the air flow also flows through the functional member due to the pressure difference. The airflow that has flowed through the functional member is removed from the allergen contained in the airflow or added with a fragrance, so that the air quality is improved and the air is blown into the room. Thus, since the air quality of the airflow flowing through the functional member is improved, the indoor air quality is gradually improved, and the indoor environment becomes comfortable.

  For this reason, the air conditioner which can aim at the improvement of indoor air quality, such as removing the allergen in intake air efficiently, can be obtained.
