JP 2003-121004 A

  In view of the above points, an object of the present invention is to provide a louver mounting structure that can be easily attached and detached.

  In order to achieve the above object, the present invention provides a louver mounting structure that is attached to an air outlet provided in a housing of an air conditioner, wherein the louver includes a louver body having a plurality of louver pieces. The louver piece has a mounting plate that is connected to the louver body so that the louver piece can be tilted rearward on both sides of the louver body, with the longitudinal direction of the louver piece being the lateral direction and the mounting direction of the louver to the housing being the rear. A receiving plate facing the mounting plate is provided on both sides in the lateral direction, a locking hole for the louver is formed in the receiving plate, and a locking claw corresponding to the locking hole is projected on the back surface of the mounting plate. The claw can be inserted into and removed from the locking hole when the mounting plate is tilted backward with respect to the louver body. When it is, it is formed so as to be retained against engaging with receiving plate on the back of the hole edge portion of the lateral outer locking hole.

  According to such a configuration, when the louver body is pulled forward so as to remove the louver from the air outlet, the mounting plate is in a rearward tilted posture inclined backward with respect to the louver body. At this time, the locking claw is also inclined inward in the lateral direction, and the locking claw can be inserted into and removed from the locking hole. When the louver body is continuously pulled forward, the locking claw comes out of the locking hole.

  Also, when attaching the louver to the air outlet, align the position of the locking claw and the locking hole with the mounting plate in the backward tilted position, push the louver body backward, and lock the locking claw. Insert into the hole. Thereafter, when the louver body is further pushed backward, the backward tilting of the mounting plate with respect to the louver body is released, and the locking claw is engaged with the back surface of the hole edge on the lateral side of the locking hole to prevent the louver from coming off. It is attached to the outlet.

  Therefore, according to the present invention, the louver can be attached / detached only by the work from the front side of the housing, and it is not necessary to turn around the both sides in the lateral direction of the housing and turn the screw as in the prior art, and the louver can be easily attached / detached. Thus, the maintainability of the louver is improved.

  Hereinafter, an embodiment of the louver mounting structure of the present invention will be described using a gas fan heater 1 as an air conditioner shown in FIGS. The gas fan heater 1 includes a housing 2 having a blower outlet 2a at the lower front portion, and hot air generating means 3 (see FIG. 3) built in the housing 2.

  As shown in FIGS. 2 and 3, the housing 2 includes a bottom plate 21 that is substantially rectangular in the lateral direction, a substantially rectangular rear plate 22 that rises upward from the rear edge of the bottom plate 21, and a rear plate 22. Side plates 23, 23 extending forward along the lateral side edges of the bottom plate 21 from both lateral side edges of the bottom plate 21. The rear plate 22 is provided with an air supply port 22a, and a receiving plate 23a projecting inward in the lateral direction is provided at the front end edges of the side plates 23 and 23.

  The hot air generating means 3 sucks room air from the air supply port 22a by the operation of the hot air fan, mixes the sucked air with the combustion exhaust gas of the burner through the air passage, and blows out hot air from the outlet 2a.

  The side plates 23 and 23 of the housing 2 are provided with synthetic resin ears 4 that are positioned above the outlet 2a and project outward in the lateral direction. A handle portion 4 a (see FIG. 2) that is recessed forward is recessed in the rear upper portion of the ear portion 4. If the handle portion 4a is recessed in the ear portion 4 in this way, unlike the case where the handle portion is recessed in the side plate 23 of the housing 2 as in the prior art, it is caused by interference with the housing built-in product such as the hot air generating means 3 Without being restricted, it is possible to increase the recess depth of the handle portion 4a so that the finger can be easily hooked.

  Although it is conceivable that the handle portion is provided on the lateral side surface of the ear portion 4, if the handle portion is provided on the lateral side surface of the ear portion 4, the arm must be widened in the lateral direction and the finger must be hung on the handle portion. It is not easy to hold. In the gas fan heater 1 according to the embodiment, the handle 4a is provided above the back of the ear 4, so that it is possible to put a finger on the handle 4a without extending the arm so much, and the handle 4a is recessed. Coupled with the fact that the depth can be increased, even a person whose fingertip power has weakened can easily lift the handle 4a with his / her finger.

  Moreover, since the ear | edge part 4 is located above the blower outlet 2a and has protruded from the side plates 23 and 23 of the housing 2 to the horizontal direction, the gas fan heater 1 brings on the shape like a thin liquid crystal television, and is not in the past. It can be a novel design.

  The ear portion 4 is provided with a plurality of substantially L-shaped projecting pieces 4b that protrude inward in the lateral direction and whose distal ends are bent backward. The protruding piece 4b is inserted into a plurality of hole portions 23b formed in the side plate 23, and the ear portion 4 is slid rearward with respect to the side plate 23, whereby the bent portion at the tip of the protruding piece 4b becomes the hole portion 23b. The ear 4 is prevented from coming off by engaging with the back of the hole edge on the rear side.

  A metal reinforcing plate 41 is attached to the front surface of the ear portion 4. A pair of upper and lower projecting pieces 41 a projecting inward in the lateral direction is provided at the lateral inner edge of the reinforcing plate 41. The tip of the upper protruding piece 41a is bent downward, and the tip of the lower protruding piece 41a is bent upward. Each side plate 23 is provided with a pair of upper and lower holes 23c and 23c corresponding to the pair of upper and lower protrusions 41a and 41a. The lower hole edge part of the upper hole part 23c is an inclined edge inclined backward and upward, and the upper hole edge part of the lower hole part 23c is an inclined edge inclined backward and downward. Each protrusion 41a is inserted into the front part of each hole 23c when the protrusion 4b of the ear part 4 is inserted into the hole 23b of the side plate 23. And when the ear | edge part 4 is slid back with respect to the side plate 23 and the protrusion 4b and the hole 23b engage, the bending part of the front-end | tip of each protrusion 41a is behind the inclined edge of each hole 23c. Engage with the back of the end. In this state, there is no vertical clearance of each protrusion 41a with respect to each hole 23c, and the ear portion 4 is positioned without backlash with respect to the side plate 23 in the vertical direction.

  An extension piece 41 b that extends forward is connected to the lateral inner edge of the reinforcing plate 41. A flange 41c that is bent inward in the lateral direction is connected to the distal end edge of the extension piece 41b. The flange 41c slides backward with respect to the side plate 23 with respect to the side plate 23, and when the projecting piece 4b and the hole 23b are engaged with each other, the flange 41c contacts the front surface of the receiving plate 23a. Screwed to the receiving plate 23a.

  The housing 2 includes a rear plate 22, a side plate 23, and a top plate 24 formed in a substantially fan shape along the outer edge of the ear portion 4. The top plate 24 is attached so as to cover the upper surface of the ear portion 4. Yes. Thereby, even if the gas fan heater 1 is viewed from above, the boundary line between the housing 2 and the ear portion 4 does not appear in the appearance, and the appearance can be kept good.

  Further, the housing 2 includes a front panel 25 as shown in FIG. The front panel 25 is located above the air outlet 2 a and is attached so as to extend to the lateral outer edges of the ear portions 4, 4 and cover the front surfaces of the ear portions 4, 4. Thereby, the external appearance can be made favorable without the boundary line of the housing 2 and the ear | edge part 4 appearing in the front surface of the gas fan heater 1. FIG. In FIG. 3, the front panel 25 is omitted.

  A louver 5 is provided at the air outlet 2a. The louver 5 is a metallic louver body 51 having a plurality of louver pieces 51 a extending in the lateral direction, and a synthetic resin attachment that is tiltably connected to the louver body 51 at both sides in the lateral direction. It consists of plates 52 and 52.

  As shown in FIGS. 4 and 5, projecting pieces 51 b projecting in the lateral direction are provided on both lateral sides of the back surface of the louver body 51. Further, a pressing portion 52 a extending backward is formed on the inner edge of the mounting plate 52 in the horizontal direction. Further, the laterally inner edge of the back surface of the mounting plate 52 has a tip that is inward in the lateral direction so that it comes into contact with the back surface of the overhanging piece 51b with the presser portion 52a in contact with the front surface of the overhanging piece 51b. A pair of upper and lower presser claws 52b, 52b that are bent in a straight line are provided. The mounting plate 52 is connected to the louver body 51 by sandwiching the overhanging piece 51b between the pressing portion 52a and the pressing claw 52b from the front-rear direction.

  Further, in order to prevent the mounting plate 52 from falling off the louver main body 51, a protruding piece 51c is provided at the tip of the overhanging piece 51b and extends laterally outwardly between the presser claws 52b, 52b. A claw portion 51d that protrudes inward in the lateral direction is formed by notching the inside of 51c in a U-shape, and the claw portion 51d is inclined forward as shown in FIG. It is made to contact | abut to the horizontal direction outer side. Further, the upper edge of the protruding piece 51 c comes into contact with the lower surface of the upper holding claw 52 b, the lower edge of the protruding piece 51 c comes into contact with the upper surface of the lower holding claw 52 b, and the mounting plate 52 moves up and down with respect to the louver body 51. Positioned in the direction.

  In addition, a recessed portion 52c that is recessed forward is formed in the laterally outer side portion of the distal end surface of the presser portion 52a. Further, the front surface of the bent portion at the tip of each presser claw 52b is formed as an inclined surface inclined backward inward in the lateral direction. Due to the recess 52c and the inclined surface of the bent portion of the presser claw 52d, the mounting plate 52 can be tilted backward with respect to the louver body 51 as shown in FIG.

  A locking claw 52d having a tip jaw projecting outward in the lateral direction and a guide projection 52e positioned on the laterally inner side of the locking claw 52d protrude from the laterally outer portion of the rear surface of the mounting plate 52. It is installed. The mounting plate 52 faces the receiving plate 23a, and the receiving plate 23a is provided with locking holes 23d corresponding to the locking claws 52d of the mounting plate 52 and the guide protrusions 52e.

  In order to attach the louver 5 to the air outlet 2a, first, the attachment plate 52 is tilted backward with respect to the louver body 51 as shown in FIG. In this state, the locking claws 52d and the guide protrusions 52e are aligned with the positions of the locking holes 23d, and the louver body 51 is pushed backward toward the outlet 2a. According to this, the locking claw 52d and the guide protrusion 52e are inserted into the locking hole 23d, and the lateral outer edge of the mounting plate 52 abuts on the receiving plate 23a. Subsequently, when the louver body 51 is pushed backward, the backward inclination of the mounting plate 52 is eliminated as shown in FIG. When the backward inclination of the mounting plate 52 is eliminated, the jaw portion of the locking claw 52d is engaged with the back surface of the hole edge portion on the laterally outer side of the locking hole 23d and is prevented from coming off from the receiving plate 23a. Further, the guide protrusion 52e comes into contact with the hole edge on the inner side in the lateral direction of the locking hole 23d, and the mounting plate 52 is positioned laterally with respect to the receiving plate 23a. In this way, the louver 5 is attached to the air outlet 2a.

  In the gas fan heater 1 of the embodiment, a screw hole 31b is formed in the front side edge of the opening 31a at the lower front of the ventilator 31 in order to more securely fix the louver 5 to the air outlet 2a. The louver body 51 is screwed into the hole 31b. The engagement between the locking claw 52a and the locking hole 23d makes it easy to align the screw hole 31a of the ventilation rod 31 with the screw hole provided in the louver body 51, and all the screws are stopped from the front. Therefore, unlike the conventional case where the louver is screwed from both sides in the lateral direction, the louver can be easily attached and detached.

  When removing the louver 5 from the air outlet 2a, the screwing of the louver body 51 is released, and the louver body 51 is pulled forward. When the louver main body 51 is pulled forward, the mounting plate 52 has a rearward inclined posture inclined backward with respect to the louver main body 51 because the locking claw 52d is engaged with the locking hole 23d of the receiving plate 23a. Become. At this time, the locking claw 52d is inclined toward the louver body 51 when the mounting plate 52 is inclined rearward, and the engagement between the locking claw 52d and the locking hole 23d is released. By further pulling the louver 5 forward from this state, the locking claw 52d comes out of the locking hole 23d, and the louver 5 is removed from the outlet 2a.
