The indoor fan 103 sucks air in the air-conditioning target space, passes it through the indoor heat exchanger 102, and discharges the conditioned air after heat exchange is performed into the air-conditioning target space. The indoor unit 101 is installed on the ceiling in the building 1 such as an office building, and the outdoor unit 110 is installed outside the building 1.

(2) Detailed Configuration of Blower Unit The configuration of the indoor unit 101 that is an example of the blower unit according to the present invention will be described in more detail below with reference to FIGS.

(2-1) Each component FIG. 2: has shown the indoor unit 101 of the state installed in the ceiling in a building. 2 in FIG. 2 is a ceiling board. The indoor unit 101 includes a suction port forming member that forms a suction port 121 for sucking indoor air into the casing of the indoor unit 101 on the ceiling. Specifically, a casing 121a in which a suction port 121 as shown in FIG. 3 is formed is installed on the ceiling. Moreover, the indoor unit 101 includes a blower outlet forming member that forms a blower outlet 122 on the ceiling for blowing the sucked air into the room. Specifically, the casing 122a shown in FIG. 2 in which the air outlet 122 is formed is installed on the ceiling. The casing 121 a that forms the suction port 121 is connected by a duct 125 so as to communicate with the internal space of the casing 126 that houses the indoor fan 103 and the indoor heat exchanger 102. The casing 122 a having the air outlet 122 is also connected by a duct 127 so as to communicate with the internal space of the casing 126.

  FIG. 3 shows the appearance of the casing 121 a that forms the suction port 121. The suction port 121 is covered with a panel 128a having a plurality of slits in a lattice shape. The panel 128 a is formed with an insertion port 128 that is an opening through which the nozzle of the cleaner can be inserted into the suction port 121, that is, the indoor unit 101. A lid made up of two doors is attached to the insertion slot 128. When the lid is pushed by the nozzle to be inserted into the insertion port 128, the two doors open inwardly, the nozzle is received in the insertion port 128, and when the nozzle is pulled out from the insertion port 128, the hinge is attached to the hinge. It is configured to close by the biasing force of the attached spring.

  Returning to FIG. 2 showing the inside of the casing 121 a, a filter 124 is installed downstream of the suction port 121. The filter 124 collects dust contained in the air sucked from the suction port 121. The filter 124 is preferably arranged substantially vertically for the reason described later. In the present embodiment, the filter 124 covers the opening 129 to the duct 125 that communicates the casing 121a that is a suction port forming member and the internal space of the casing 126 in which the indoor fan 103 and the indoor heat exchanger 102 are stored. It is installed almost vertically. A suction box 123 is installed so as to be in contact with or close to the filter 124. The suction box 123 will be described later.

  The suction port forming member such as the casing 121a in which the suction port 121 is formed and the insertion port forming member such as the panel 128a in which the insertion port 128 is formed may be a single casing. Moreover, a single casing may be sufficient as a blower outlet formation member like the casing 122a in which the blower outlet 122 was formed, and a suction inlet formation member. The suction port forming member, the blowout port forming member, and the insertion port forming member may constitute a single casing.

  The filter 124 is preferably a pleat type filter. The pleat type filter has a larger area in contact with air than a normal type filter, and can collect more dust contained in the air. However, other types of filters may be used.

(2-2) Suction Box Next, the suction box 123 will be described with reference to FIGS. As shown in FIG. 4, the suction box 123 combines a hollow box-shaped suction box 123 main body with a box 123a (hereinafter referred to as a nozzle guide 123a) that is smaller than the main body and is open on one side. It is shaped like letting The suction box 123 main body is preferably provided with an opening at a position in contact with or close to the filter 124. Although the number of the openings may be one, it is preferable that a plurality of openings are provided. Specifically, for example, the main body of the suction box 123 shown in FIG. 4 has a surface facing the filter 124 that has a ridge-shaped unevenness in accordance with the shape of the pleat type filter 124. The surface is provided with suction slits 123b which are a plurality of slit-shaped openings. The suction box 123 does not always need to be in a position close to the filter 124, as long as the suction box 123 can be moved to a position close to the filter 124 by being pushed by a nozzle of a cleaner as described later when cleaning the filter 124. Therefore, the suction slit 123b only needs to be in contact with or close to the filter 124 when the filter 124 is cleaned.

  The suction box 123 main body has a hemispherical bulge at the center of the joint surface with the nozzle guide 123a, and an opening 123c at the center of the bulge. The nozzle guide 123a is shaped like a hollow cube or a rectangular parallelepiped, but has no surface on the side facing the joint surface with the suction box 123 body, and the internal space of the nozzle guide 123a is external. Has been released. The nozzle guide 123a receives the nozzle 2 of the cleaner from the open part into the internal space of the nozzle guide 123a, and guides the mouth of the nozzle 2 of the cleaner and the opening 123c to join. Thus, when the suction function of the vacuum cleaner is exerted in a state where the internal space of the nozzle 2 of the vacuum cleaner and the internal space of the suction box 123 main body are communicated, the suction that is in contact with or close to the filter 124 included in the suction box 123 main body. Dust adhering to the filter 124 can be sucked and removed from the slit 123b.

  The suction box 123 is preferably supported by the support member so that the suction box 123 can move along the insertion direction of the nozzle 2 of the cleaner. Furthermore, when the filter 124 is installed substantially vertically as shown in FIG. 2, the suction box 123 is supported by a support member so as to be movable in a substantially vertical direction along the surface of the filter 124. It is preferable that Note that the filter 124 is preferably installed substantially vertically. An operator standing on the floor in the building can clean the filter 124 by pushing the suction box 123 using the nozzle 2 by simply inserting the nozzle 2 of the vacuum cleaner into the suction port 121 in a substantially vertical direction. From the floor, it is easier to insert the nozzle 2 of the vacuum cleaner into the insertion port 128 in the substantially vertical direction.

  It is preferable that the insertion port 128 for inserting the nozzle 2 of the vacuum cleaner is disposed directly below the center of gravity in the plan view of the suction box 123. Thereby, the center of gravity of the suction box 123 can be pushed by the nozzle 2 of the vacuum cleaner, so that the suction box 123 can be moved more easily.

  Specifically, for example, the suction box 123 is preferably movably supported by a support member as shown in FIGS. As shown in FIG. 4, when the surface facing the filter 124 of the main body of the suction box 123 is the front surface and the surface to which the nozzle guide 123a is joined is the bottom surface, it has two surfaces corresponding to the side surfaces. The two side surfaces extend further upward than the front surface. Four gears 132 are attached to the two side surfaces. A total of four gears 132 are arranged in two on each side surface, ie, an upper stage and a lower stage. The upper two gears 132 are arranged at the side portion extending upward from the front surface, and the lower two gears 132 are arranged at the side portion positioned below the upper side of the front surface. One connecting shaft 131a is attached to the side portion extending upward from the front surface so as to cross the upper surface of the suction box 123 main body and penetrate both side surfaces. Of the two gears 132 on the upper side of each side surface, the gear 132 located on the side close to the front is passed through the connection shaft 131a and fixed in the vicinity of both ends of the connection shaft 131a. The connecting shaft 131a is rotatably attached to the main body of the suction box 123. When the connecting shaft 131a rotates, the two gears 132 attached to the connecting shaft 131a rotate. The other gear 132 is passed through the three shafts 131b fixed and attached so as not to rotate in a state of protruding from each side surface, and is attached rotatably. These gears 132 protruding from each side are fitted in the rack 133 as shown in FIGS.

  As shown in FIGS. 5 and 6, the rack 133 is adjacent to each of the two vertical sides of the surface of the inner wall of the casing 121 a where the opening 129 to the duct 125 in which the filter 124 is installed is formed. One for each of the two inner wall surfaces is attached in parallel to the surface of the filter 124. The cross section orthogonal to the longitudinal direction of the rack 133 has a U shape (or a shape in which the U shape is reversed). The two racks 133 are installed so that the U-shaped open portions face each other. The rack 133 includes teeth that mesh with the gears on the inner side of portions corresponding to the upper and bottom sides of the U-shape. The teeth of the rack 133 are in contact with and meshed with the gear 132 attached to the side surface of the suction box 123. When a substantially vertical force is applied to the suction box 123, the teeth of the gear 132 mesh with the teeth of the rack 133, the gear 132 rotates, and the suction box 123 moves along the rack 133.

  As shown in FIGS. 6 and 7, the lever 134 is always in contact with the upper surface of the main body of the suction box 123. One end of the lever 134 is attached to the inner wall surface of the casing 121a. The inner wall surface is a surface facing the opening 129 to the duct 125 covered by the filter 124. The lever 134 is attached to the surface by a bolt and a nut so as to be movable up and down by drawing an arc with an end attached to the surface as an axis. The lever 134 has a hook for hooking one end of the spring 135 on one side surface. The hook is located between an end of the lever 134 attached to the inner wall of the casing 121a and a central point that bisects the lever 134 in the longitudinal direction. The other end of the spring 135 attached to the hook is attached to a hook attached to the same inner wall surface of the casing 121a as the lever 134 is attached. The hook attached to the inner wall surface is located below the position where the lever 134 is attached to the inner wall surface. The urging force of the spring 135 acts to hold down the upper surface of the suction box 123 via the lever 134. As a result, when the suction box 123 pushed away from the insertion port 128 by the nozzle 2 of the cleaner is weakened in the force to push the nozzle 2 of the cleaner in the insertion direction, the suction box 123 is moved toward the insertion port 128 by the lever that pushes the upper surface. Pushed back. Therefore, the worker who cleans the filter 124 only needs to apply force when pushing the nozzle 2 of the cleaner inserted through the insertion port 128 in the insertion direction.

(4) Modification (4-1)
In the above embodiment, the suction box 123 is movably supported by a support member including a spring mechanism including a lever 134 and a spring 135. However, in other embodiments, the suction box 123 may be movably supported by a support member having another configuration. For example, the suction box 123 may be movably supported by a support member having a belt mechanism as shown in FIG. In this case, the configuration of the suction box 123 and the support member that movably supports the suction box 123 is specifically modified from the above embodiment as follows.

  As shown in FIG. 8, the suction box 201 of this modification has two plate-like protrusions 201d (hereinafter referred to as belt fixing members 201d) instead of gears 132 on each side of the suction box 201 main body. I have. The nozzle guide 201a, the suction slit 201b, and the opening 201c have the same configuration as the nozzle guide 123a, the suction slit 123b, and the opening 123c. Therefore, since the suction box 201 of this modification has the same configuration as the suction box 123 according to the above-described embodiment except that a belt fixing member 201d is provided on each side surface, the description thereof is omitted.

  The suction box 201 is attached to the two timing belts 205 by sandwiching the timing belt 205 from both sides by the two belt fixing members 201d and fastening them with screws or the like. The timing belt 205 is hooked to gears 203 and 204 attached to the connecting shaft 202a and the shaft 202b attached to the two inner wall surfaces adjacent to the two vertical sides of the surface of the casing 121a where the opening 129 to the duct 125 is formed. It has been. The connecting shaft 202a extends above the opening 129 across the two inner wall surfaces facing the casing 121a. The aforementioned gear 203 is attached in the vicinity of both ends of the connecting shaft 202a. Further, a shaft 202b is attached to a portion of each inner wall surface located below the opening 129 to the duct 125 so that each shaft 202b protrudes from the inner wall surface, and each shaft 202b protruding from each inner wall surface. The above-mentioned gear 204 is attached in the vicinity of the tip of the. Further, one guide 206 is attached to each inner wall surface in parallel with the timing belt 205. Each guide 206 has a guide groove 206a along its longitudinal direction. The two guides 206 are installed such that the guide grooves 206a face each other. The tip of each belt fixing member 201d protruding from each side surface of the suction box 201 is inserted into the guide groove 206a. The suction box 201 moves upward along the guide groove 206a by being pushed by the nozzle 2 of the cleaner inserted through the insertion port 128. However, when the upward pushing force by the nozzle 2 of the cleaner is weakened, the timing belt 205 on the side where the suction box 201 is attached is pulled downward by the weight of the suction box 201 itself attached to the timing belt 205. At this time, the gear 203 attached to the connecting shaft 202a and the gear 204 attached to the shaft 202b rotate as the timing belt 205 moves, and the suction box 201 moves downward along the guide grooves 206a of the two guides 206.

However, in other embodiments, the filter 124 may be installed at another position as long as it is between the inlet 121 inside the indoor unit 101 and the indoor fan 103. For example, the filter 124 may be installed vertically in the duct 125 so that the entire circumference of the filter 124 is in contact with the entire circumference of the inner wall of the duct 125. In this case, the suction box 123 or 201 is installed nearer to the filter 124 and closer to the suction port 121 than the position in the duct 125 where the filter 124 is installed. The insertion port 128 is formed at a site located directly below the center of gravity in a plan view of the suction box 123 or 201 on the wall of the duct 125.

  The present invention is useful for easily cleaning a blower unit such as an indoor unit of a ceiling-mounted air conditioner.
