Description

  The present invention relates to an air conditioner, and more particularly, to an air conditioner including an indoor heat exchanger having a first heat exchange part and a second heat exchange part for exchanging heat with room air, and a seal plate in contact with the indoor heat exchanger. .

  The indoor heat exchanger of the air conditioner includes, for example, a first heat exchange section on the front side and a second heat exchange section on the back side as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2005-24223). It is a form connected to a reverse V-shape in side view. In this indoor heat exchanger, a seal plate is installed between the first heat exchange unit and the second heat exchange unit so that the heat exchange of the indoor air is reliably performed, and the air is exchanged with the first heat exchange unit. Passing through the gap with the second heat exchange section is prevented.

  However, in the seal plate described in Patent Document 1, since the fixing hook is applied to both the first heat exchange unit and the second heat exchange unit, the first heat exchange unit and the second heat exchange during assembly are arranged. The hook on the side of the first heat exchange part is hooked by the variation in the distance from the part, but there is a tendency that the hook on the side of the second heat exchange part is not hooked.

  An object of the present invention is to provide an air conditioner including a seal plate that is hardly affected by a change in the distance between the first heat exchange unit and the second heat exchange unit and improves the mounting workability.

An air conditioner according to a first aspect of the present invention includes a heat exchanger having adjacent first heat exchange units and second heat exchange units, and an air blocking member in contact with the first heat exchange unit and the second heat exchange unit. It is an air conditioner provided. The first heat exchange unit and the second heat exchange unit include a plurality of fins and a plurality of heat transfer tubes. The fins are arranged in parallel at a predetermined interval. The heat transfer tube penetrates the plurality of fins in the thickness direction. The air blocking member includes a main body portion, a protrusion, a plurality of hooks, and a rotation stop portion. The main body covers at least a gap between the first heat exchange unit and the second heat exchange unit. The protrusion has a V-shaped cross section and protrudes from the main body. The hook is hooked on the heat transfer tube of the first heat exchange unit together with the protrusion, and is not hooked on the heat transfer tube of the second heat exchange unit. The rotation stop portion contacts the fins of the first heat exchange portion while the hook is hooked on the heat transfer tube of the first heat exchange portion, and prevents the main body portion and the hook from rotating.

  In this air conditioner, the air blocking member is attached to the heat exchanger by a plurality of hooks that are hung on the heat transfer tube of the first heat exchange unit and not on the second heat exchange unit. 2 Not easily affected by fluctuations in the distance from the heat exchange section. As a result, when the air blocking member is attached, the worker completes the mounting by simply pushing the air blocking member into the heat exchanger, so that workability is improved. Moreover, since the rotation stopper is in contact with the fins of the first heat exchange part while maintaining the state where the hook is hooked on the heat transfer tube of the first heat exchange part, the rotation of the main body part is prevented. Therefore, the main body portion does not float up, and air coming toward the gap between the first heat exchange portion and the second heat exchange portion can be prevented.

The front panel 10b covers the front opening of the front grill 10a, and the upper end of the front panel 10b is rotatably supported by the front grill 10a and can operate in a hinged manner.

  The indoor heat exchanger 21 and the indoor fan 31 are attached to the bottom frame 11. The indoor heat exchanger 21 exchanges heat with the passing air. The indoor fan 31 blows the air taken in from the room against the indoor heat exchanger 21 and then blows it into the room.

  A blower outlet 15 is provided on the lower surface portion of the casing 10, and a horizontal flap 17 that guides air blown from the blower outlet 15 is provided at the blower outlet 15. The horizontal flap 17 is driven by a motor (not shown) and can open and close the air outlet 15 as well as change the air blowing direction.

  A filter 41 is disposed between the front grill 10 a of the casing 10 and the indoor heat exchanger 12. The filter 41 removes dust contained in the air that flows in toward the indoor heat exchanger 12.

(3) Detailed configuration (3-1) Indoor heat exchanger 21
As shown in FIG. 2, the indoor heat exchanger 21 is attached so as to surround the front, upper, and rear of the indoor fan 31. The indoor heat exchanger 21 exchanges heat between the indoor air sucked from the suction port of the front grill 10a by the drive of the indoor fan 31 and the refrigerant.

  The indoor heat exchanger 21 is a heat exchanger in which a first heat exchanging part 21a located on the front side and a second heat exchanging part 21b located on the rear side are connected in an inverted V shape in a side view.

  The second heat exchanging portion 21b is disposed so that the upper end is inclined toward the front of the indoor unit 2 and covers the rear upper portion of the indoor fan 31 from above. The first heat exchanging part 21 a is arranged so that the upper end of the first heat exchanging part 21 a is inclined toward the rear of the indoor unit 2 and covers the upper part of the indoor fan 31 in front of the second heat exchanging part 21 b. The upper end of the first heat exchange unit 21a is close to the upper end of the second heat exchange unit 21b. As described above, the top end of the first heat exchanging portion 21a and the upper end of the second heat exchanging portion 21b are close to each other, whereby an inverted V-shaped apex is formed.

  The 1st heat exchange part 21a and the 2nd heat exchange part 21b are comprised from the several heat exchanger tube 220 and the several fin 210 by which the heat exchanger tube 220 was penetrated. The heat transfer tube 220 has a straight tube portion 221 that penetrates the fins 210 and a U-shaped tube portion 223 that connects two adjacent straight tube portions 221.

  The fins 210 are thin plate-like members having the same shape as the cross section of the first heat exchange part 21a and the second heat exchange part 21b, and are spaced apart from each other in the longitudinal direction of the straight pipe part 221 of the heat transfer tube 220. Are arranged to be stacked.

(3-2) Seal plate 24
As shown in FIG. 2, the seal plate 24 is a resin member, and is attached so as to cover a gap at the top formed by the first heat exchange portion 21a and the second heat exchange portion 21b. The passage of air between the heat exchange unit 21a and the second heat exchange unit 21b is suppressed.

  FIG. 3 is a front view of the indoor unit 2 from which the casing 10 and the filter 41 are removed. FIG. 4 is a partial cross-sectional view taken along line AA in FIG. FIG. 5 is a partial cross-sectional view taken along line BB in FIG. 3 to 5, the seal plate 24 includes a main body 240, a plurality of hooks 250, and a plurality of rotation stoppers 260.

  Since the main body 240 is covered from above along the top, it has a V-shaped cross-sectional shape so as to match the shape of the top formed by the first heat exchange part 21a and the second heat exchange part 21b. (See FIG. 4). Since the gap at the top portion exists along the longitudinal direction of the indoor heat exchanger 21, the main body 240 also has an elongated shape having a length substantially the same as the longitudinal length of the indoor heat exchanger 21.

  The hooks 250 are provided at substantially equal intervals along the longitudinal direction of the main body 240. The hook 250 enters the gap between the fins 210 of the first heat exchanging part 21a and is hooked on the straight pipe part 221 of the heat transfer pipe 220. Therefore, the hook 250 is formed in a thin plate shape and has a circumferential length on the outer circumference of the straight pipe part 221. A U-shaped or C-shaped configuration is adopted so as to hang over half of the length. Therefore, it is difficult for the seal plate 24 to fall off the indoor heat exchanger 21.

  Further, as shown in FIG. 5, the hook provided at the end of the main body 240 among the plurality of hooks 250 is located in a region where the fins 210 are not provided, and is not a straight pipe part 221 but a U-shaped pipe part 223. It takes. This hook is referred to as an auxiliary hook 250a.

  Since the auxiliary hook 250a does not enter the gap between the fins 210, the auxiliary hook 250a does not need to be formed in a thin plate shape and can be held in close contact with the outer peripheral surface of the U-shaped tube portion 223 so that the U-shaped tube portion 223 can be securely held. A surface is formed.

  The rotation stoppers 260 are provided at substantially equal intervals along the longitudinal direction of the main body 240. The rotation stopper 260 protrudes in a cantilevered manner from the end of the main body 240 on the first heat exchanging portion 21 a side, and is in contact with the fins 210. Therefore, the main body portion 240 is prevented from rotating about the heat transfer tube 220 on which the hook 250 is hooked, and the main body portion 240 is prevented from being lifted or displaced.

  FIG. 6 is a plan view of the seal plate 24 viewed from the indoor heat exchanger 21 side of FIG. In FIG. 6, the main body 240, the hook 250, and the rotation stopper 260 are integrally formed, and the productivity is higher than that in which the three members are individually joined.

  Furthermore, the hook 250 is shaped so as to protrude from the rotation stop portion 260 toward the first heat exchange portion 21a. Since the hook 250 has a thin plate shape, the configuration in which the operator protrudes from the rotation stopper 260 is more difficult for the operator to enter the gap between the fins 210 than the configuration in which the hook 250 protrudes alone from the main body 240. Good sex. Moreover, since the hook 250 and the rotation stopper 260 are close to each other, the size is small.

(4) Features (4-1)
In the air conditioner 1, since the plurality of hooks 250 of the seal plate 24 are hooked on the heat transfer tube 220 of the first heat exchange portion 21a and not the heat transfer tube 220 of the second heat exchange portion 21b, the first heat exchange portion 21a It is difficult to be affected by the variation in the distance from the second heat exchange unit 21b. When the operator attaches the seal plate 24, the installation is completed simply by pushing the seal plate 24 into the indoor heat exchanger 21, so that workability is improved.

  Further, since the rotation stopper 260 is in contact with the fins 210 of the first heat exchange unit 21a while maintaining the state where the hook 250 is hooked on the heat transfer tube 220 of the first heat exchange unit 21a, the rotation of the main body 240 is performed. Is prevented. Therefore, the main body 240 does not float, and air coming toward the gap between the first heat exchange unit 21a and the second heat exchange unit 21b can be blocked.

(4-2)
Since the hook 250 is hooked on or opposed to the outer periphery of the heat transfer tube 220 for more than half of the circumferential length thereof, the hook 250 is hooked on the heat transfer tube 220 so as to sandwich the outer periphery thereof. It is difficult to drop off from the exchanger 21.

(4-3)
The rotation stopper 260 protrudes from the main body 240 and is supported in a cantilever shape. Further, since the hook 250 is formed on the cantilever portion of the rotation stopper 260, the hook 250 and the rotation stopper 260 are close to each other. Therefore, the seal plate 24 becomes small.

(4-4)
An auxiliary hook 250a for hooking the U-shaped tube portion 223 is provided at the end of the seal plate 24, and an operator must attach the auxiliary hook 250a to the U-shaped tube portion 223 of the first heat exchanging portion 21a. Thus, the positions of the plurality of hooks 250 are determined, and thereafter, the hooks 250 can be mounted without worrying about the directionality.

  As described above, according to the present invention, the mounting property of the seal plate is not easily affected by the variation in the distance between the first heat exchange unit 21a and the second heat exchange unit 21b. This is useful for members that cover the gaps in the heat exchange section.
