Description

  The present invention relates to an air conditioner including a heat exchanger and a blower.

  In general, in an office building or the like, a space is formed under a free access floor, cold air or warm air is supplied to the space, and the cold air or warm air is blown into a room from a floor outlet formed on the floor surface. An air conditioning system has been proposed (see, for example, Patent Document 1).

In such an air conditioner such as a floor-standing type, generally, a heat exchanger and a blower are provided in a housing, and the primary air side and the secondary air side of the heat exchanger are arranged on the front side of the housing. The front panel that covers both sides and covers the front side of the casing is fixed to the casing with a plurality of screws.
JP-A-6-317337

  However, in the conventional configuration, the front panel that covers the front side of the casing is screwed to the casing via a plurality of screws, so that the heat exchanger, blower, etc. in the casing are maintained. In this case, it is difficult to remove all screws, and there is a problem that maintenance is extremely difficult.

  Therefore, an object of the present invention is to provide an air conditioner that can solve the above-described problems of the prior art and can easily perform maintenance without removing the screws of the front panel.

  In order to achieve the above object, the invention described in claim 1 is directed to a heat exchanger disposed in a housing, and a primary air side and a secondary air side of the heat exchanger face the front side of the housing, An inner panel that seals the secondary air side, and the inner panel is disposed in front of the inner panel so that the inner panel can be held, covers a front area of the housing including the primary air side, and the upper end and the lower end are connected via hinges. A kannon-type door body that can be freely opened and closed connected to a housing, and a deflection correction mechanism that presses the door body toward the housing at a substantially central position in the height direction of the door body. is there. According to a second aspect of the present invention, there is provided the bracket according to the first aspect, wherein the deflection correcting mechanism is fixed to the housing side and has a long hole substantially parallel to the door body when closed, and the bracket. A connecting rod having one end movably attached to the elongated hole, and a hole fixed to the door body and attached to the other end of the connecting rod, and the hole portion when the door body is opened. Is located on the outside of the housing with respect to the extension line of the long hole of the bracket, and when the door is closed, the arm portion is formed so that the hole portion is located on the inside of the housing with respect to the extension line of the long hole of the bracket. It is characterized by having.

  According to the present invention, since it is only necessary to open the door, maintenance can be easily performed.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an indoor unit used as a free access floor type air conditioner in an office building or the like. FIG. 2 shows a state where the rear panel and both side panels of the indoor unit are removed, and FIG. 3 shows a state where the front panel of the indoor unit is further removed.

  In FIG. 3, reference numeral 1 denotes a casing framed by a frame. The indoor heat exchanger 3 is arranged in a bracing manner in the upper stage of the casing 1, and the blower 5 is arranged in the lower stage. Although not shown, the blower outlet of the blower 5 faces the opening at the bottom of the housing 1. The air sucked through the opening 1 </ b> A in the upper part of the housing 1 enters the primary air side A spreading on the front side of the indoor heat exchanger 3, and after exchanging heat with this heat exchanger 3, the back of the indoor heat exchanger 3 Enters the secondary air side B spreading to the side, is sucked in from the nozzle 5A of the blower 5 located in the space B, and blown out from the blower outlet of the blower 5 toward the opening of the bottom of the casing 1 to the floor. The

  In the present embodiment, the primary air side A and the secondary air side B of the heat exchanger 3 face the front surface 1B side of the housing 1.

  And as shown in FIG. 4, it has the internal panel 7 which seals the secondary air side B, and the housing | casing which includes the primary air side A on the front surface of this internal panel 7 so that the said internal panel 7 may be hold | maintained 1 is provided with door bodies 11 and 13 that cover all of the front area of 1 and can be opened and closed like a door.

  As shown in FIG. 5A, a lower edge claw 7A and an upper edge claw 7B are formed on the back surface of the inner panel 7, and a heat insulating material 7C is attached to the peripheral edge. As shown in FIG. 5B, after the lower edge claw 7A and the upper edge claw 7B are hooked on the frame of the housing 1 and temporarily fixed, when the door bodies 11 and 13 are tightened, the door bodies 11 and 13 are pressed to insulate. The material 7 </ b> C comes into contact with the frame, and the inner panel 7 is fixed to the housing 1. This inner panel 7 can seal the secondary air side B without screwing.

  As shown in FIG. 6, the door bodies 11 and 13 are connected to the housing 1 at two upper and lower portions on the suspending side by hinges 21 and 22, and the approximate center in the height direction is the door body 11 and 13. 13 are connected via a deflection correction mechanism 23. As shown in FIG. 7, the deflection correcting mechanism 23 includes an arm 23 </ b> A fixed to the door bodies 11 and 13, a bracket 23 </ b> B fixed to the housing 1 side, and a connecting rod 23 </ b> C spanned between the two. It has. One end of the connecting rod 23C is inserted into the hole 23F of the arm 23A, and the other end of the connecting rod 23C is inserted into the long hole 23G of the bracket 23B.

  FIG. 8A shows a state in which the door bodies 11 and 13 are opened. As shown in FIG. 8B, when the door bodies 11 and 13 are closed, the tip 23D of the connecting rod 23C moves in the direction of the arrow X in the long hole 23G of the bracket 23B. 23C is parallel to the frame of the housing 1. When the door bodies 11 and 13 are further closed, as shown in FIG. 8D, the base end 23E of the connecting rod 23C enters the inside of a line substantially parallel to the frame of the housing 1, and the approximate center of the door bodies 11 and 13 is It is pressed to the housing 1 side.

  The door bodies 11 and 13 are vertically long door bodies and are easily bent in the direction in which the center in the height direction is separated from the housing 1.

  In this embodiment, since the bending correction mechanism 23 is provided, the bending when the door bodies 11 and 13 are closed is corrected.

  Referring to FIG. 3, openings 10 </ b> A to 10 </ b> C for inserting fork claws of a forklift (not shown) are formed in lower frame 10 of housing 1 so as to avoid the outlet of blower 5. That is, the blower outlet of the blower 5 is formed between the opening 10A and the opening 10B. The openings 10 </ b> A to 10 </ b> C extend in the depth direction of the housing 1, the final end does not open, and a back panel (not shown) is disposed there.

  The distance between the fork claws is substantially fixed. When the distance is large, the fork claws are inserted into the openings 10A and 10C. When the distance is small, the fork claws are inserted into the openings 10A and 10B. A bottom plate 20 is stretched on the bottom surfaces of the openings 10A to 10C. An anchor bolt through hole 20A (not shown) is formed in the bottom plate 20. According to this, after carrying in with a forklift, installation work of an indoor unit can be completed only by inserting an anchor bolt in this through-hole 20A, and bolting to this.

  As shown in FIG. 4, a cover panel 10D is housed on the inner surface of one door body 11, and after the installation work of the indoor unit is completed, the openings 10A to 10C are covered with the cover panel 10D. Is called.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. In the above-described embodiment, the indoor unit of the free access floor system has been described. However, the present invention is not limited to this, and can be applied to, for example, a floor-standing air conditioner.
