As an example of an outdoor unit of a refrigeration air conditioner, an outdoor unit of an air conditioner will be described below.

  FIG. 1 to FIG. 14 are diagrams showing the first embodiment, FIG. 1 is a perspective view of the outdoor unit 100 of the air conditioner as viewed from the left side of the back surface, and FIG. FIG. 3 is a front view of the rear guard 6, FIG. 4 is a perspective view of the rear guard 6, FIG. 5 is a perspective view of the main part of the rear guard 6 (near the right end of the cross rail 6a), and FIG. FIG. 7 is a side view (a), a plan view (b), and FIG. 8 of a main part (near the left end of the horizontal rail 6a) of the rear guard 6. FIG. FIG. 9 is a partial perspective view of the front panel 2 as viewed from the rear, FIG. 10 is a perspective view of the right side of the rear guard 6 before being attached to the main body 1, and FIG. 12 is a perspective view showing a state in which the right side of the rear guard 6 is attached to the main body 1, and FIG. FIG. 13 is a perspective view showing a state in which the left side of the rear guard 6 is attached to the outdoor heat exchanger 7, and FIG. 14 is a view in which the left side of the rear guard 6 is pressed by the side panel 3. It is a perspective view which shows a state.

  The present embodiment is characterized in the structure for attaching the rear guard 6 provided on the outside of the outdoor heat exchanger 7 to the main body 1.

  First, the whole structure of the outdoor unit 100 of an air conditioner is demonstrated. However, the description will focus on the main body 1 (housing) that is closely related to the mounting structure of the rear guard 6. The rear guard 6 is provided on the back surface of the main body 1 (housing) so as to face the outdoor heat exchanger 7. The rear guard 6 is literally a protective member and protects the outdoor heat exchanger 7. For example, an object larger than the mesh of the rear guard 6 is prevented from hitting the outdoor heat exchanger 7. Moreover, the design property of the outdoor unit 100 of an air conditioner is improved. Furthermore, there is also an effect of prompting attention that there is an outdoor heat exchanger 7 (having danger because it has thin fins) in the vicinity of the rear guard 6. Although slightly, there is an effect of improving the strength of the main body 1 (housing).

  As shown in FIG. 1, an outdoor unit 100 of an air conditioner houses an unillustrated outdoor heat exchanger, blower, compressor, and the like inside a main body 1 (housing). The outdoor heat exchanger is incorporated in the refrigeration cycle. In the outdoor heat exchanger, the refrigerant flowing through the refrigeration cycle and the outdoor air exchange heat. The outdoor heat exchanger functions as a condenser during cooling operation and as an evaporator during heating operation. The blower blows air to the outdoor heat exchanger to promote the heat exchange. The compressor is the most important part of the refrigeration cycle. The compressor compresses the low-temperature / low-pressure gas refrigerant into a high-temperature / high-pressure gas refrigerant. The outdoor heat exchanger and the compressor will be touched on a little later.

  The main body 1 (housing) includes a front panel 2, a side panel 3, a top panel 4, a base 5 (bottom plate), a service panel (not shown), a partition plate (not shown), and the like.

  As shown in FIG. 8, the front panel 2 includes a front surface portion 2a, a side surface portion 2b (left side when viewed from the front surface), and a back surface portion 2c.

  Two air outlets 2a-1 are formed in the front surface portion 2a. The two outlets 2a-1 face two blowers (not shown). A grill (not shown) is attached to these outlets 2a-1.

  A large number of air inlets 2b-1 are opened in the side surface portion 2b.

  As will be described later, a locking portion 10 (see FIG. 9) for locking one end of the rear guard 6 (right side when viewed from the back) is formed on the back surface 2c. The locking portions 10 are provided at a plurality of locations in the vertical direction. The number of the locking portions 10 varies depending on the model. In the example of FIG. 1, there are three locking portions 10.

  The side panel 3 (an example of a main body panel) is an L-shaped panel including a side surface portion 3a and a back surface portion 3b. A service panel (not shown, provided on the front side) is combined with the side surface portion 3 a of the side panel 3. These form a substantially U-shaped space (viewed from the front) as viewed from above. This substantially U-shaped opening is partitioned by a partition plate (not shown, a partition between the outdoor heat exchanger 7 and the like and the compressor 8 (see FIG. 2) and the like) to form a machine room. The compressor 8 and the like are accommodated in the machine room. The service panel can be removed, and is removed at the time of maintenance / inspection of the outdoor unit 100 of the air conditioner.

  On the side panel 3, pressing parts 3c (see FIG. 14) for pressing the other end (the other end, the left side when viewed from the back) of the rear guard 6 are formed at three positions in the upper and lower sides.

  The top panel 4 (top panel) constitutes the top surface of the main body 1. It does not relate to the mounting of the rear guard 6.

  The base 5 (bottom plate) constitutes the bottom surface of the main body 1. The base 5 mounts a compressor 8, an outdoor heat exchanger 7, a blower (not shown), and the like.

  On the back surface of the main body 1, there is a large opening 1 a between the back surface portion 2 c of the front panel 2 and the back surface portion 3 b of the side panel 3. The opening 1 a faces the outdoor heat exchanger 7. The opening 1a becomes an air inlet. A rear guard 6 is attached to the opening 1 a so as to face the outdoor heat exchanger 7.

  FIG. 2 is a perspective view of the air conditioner outdoor unit 100 with the side panel 3 and the rear guard 6 removed. Since the side panel 3 is removed, the compressor 8 in the machine room and the end plate 7a of the outdoor heat exchanger 7 are visible.

  As will be described later, the other end of the rear guard 6 is inserted into a hole 7b (see FIG. 12) formed in the end plate 7a of the outdoor heat exchanger 7. Further, the side panel 3 is screwed into the hole 7b of the end plate 7a. The other end of the rear guard 6 is fixed by the side panel 3 and the end plate 7 a of the outdoor heat exchanger 7.

  Next, the configuration of the rear guard 6 will be described with reference to FIGS. As shown in FIGS. 3 and 4, the rear guard 6 has a lattice-like configuration including a vertical beam 6b and a horizontal beam 6a. In this example, there are four vertical bars 6b and seven horizontal bars 6a.

  An iron wire is used for the material of the vertical beam 6b and the horizontal beam 6a. The diameter of the horizontal beam 6a is about 3 mm, the diameter of the vertical beam 6b is about 2.5 mm, and the diameter of the horizontal beam 6a is larger than the diameter of the vertical beam 6b. This is because the rear guard 6 is fixed by the horizontal rail 6a. Since the vertical beam 6b is not related to the fixing of the rear guard 6, it is made thinner than the horizontal beam 6a in order to reduce the cost.

  In consideration of weather resistance, the vertical rail 6b and the horizontal rail 6a are provided with a resin coating on the surface thereof. The resin is, for example, vinyl.

  The dimension between the vertical bars 6b and the horizontal bars 6a of the rear guard 6 is about 210 mm in one example.

  The rear guard 6 is attached to the main body 1 and is attached using a part of the cross rail 6a. In the case of the rear guard 6 shown in FIGS. 3 and 4, three of the seven (upper, middle, lower) are used for attachment.

  The configuration of these three horizontal rails 6a will be described with reference to FIGS. First, the configuration of the right end of the horizontal rail 6a (one end, the right side when viewed from the back with the rear guard 6 attached to the main body 1) will be described. The horizontal rail 6a shown in FIG. 5 is positioned at the top of the three, but the other two have the same configuration.

  The right end of the horizontal rail 6a includes a bent portion 6a-2 and a U-shaped portion 6a-1. The bent portion 6a-2 is bent toward the inside (the main body 1 side). The angle (α) formed between the straight line portion at the center of the horizontal rail 6a and the bent portion 6a-2 is an obtuse angle.

  A U-shaped portion 6a-1 is formed on the right side of the bent portion 6a-2. The U-shaped part 6a-1 is parallel to the central straight part of the horizontal rail 6a and is in a state in which the U-character is rotated approximately 90 ° counterclockwise.

  The configuration of the left end portion of the horizontal rail 6a (the other end portion, the left side when viewed from the back with the rear guard 6 attached to the main body 1) will be described. As shown in FIG. 6, the left end portion of the horizontal rail 6a includes a bent portion 6a-3 and an insertion portion 6a-4. The bent portion 6a-3 is substantially symmetric with the bent portion 6a-2 at the right end. The insertion part 6a-4 is provided at the tip of the right end part. The insertion portion 6a-4 is provided at a substantially right angle with respect to the straight portion at the center of the horizontal rail 6a. The insertion portion 6a-4 extends toward the main body 1 side.

  Furthermore, as shown in FIG. 7, the insertion part 6a-4 is inclined downward with respect to the horizontal direction. That is, as shown to Fig.7 (a), the insertion part 6a-4 inclines 10-15 degrees below with respect to the horizontal direction.

  The reason why the bent portion 6a-2 and the bent portion 6a-3 are provided at the left and right end portions of the horizontal rail 6a is to provide elasticity to the horizontal rail 6a.

  Next, the configuration on the main body 1 side with which the rear guard 6 is engaged will be described. 9 is a partial perspective view of the front panel 2 as seen from the back, FIG. 10 is a perspective view showing a state before the right side of the rear guard 6 is attached to the main body 1, and FIG. 11 is a state where the right side of the rear guard 6 is attached to the main body 1. It is a perspective view shown.

  As shown in FIG. 9, the rear portion 2 c of the front panel 2 is provided with a locking portion 10 at the end thereof. The latching | locking part 10 is provided in several places as needed in the up-down direction. In this Embodiment, the latching | locking part 10 is provided in three places (refer FIG. 1). However, there may be any number of the locking portions 10 and there may be locking portions 10 that are not used.

  FIG. 9 shows the uppermost locking portion 10. And the latching | locking part 10 consists of the long hole 10a long in an up-down direction, and the latching hole 10b smaller than the long hole 10a opened under the long hole 10a. The end of the back surface 2c of the front panel 2 is bent approximately 90 ° inward. The long hole 10a and the locking hole 10b are opened at the corners.

  When attaching the rear guard 6 to the main body 1, first, the right end portion of the horizontal rail 6 a is locked to the locking portion 10 of the back surface portion 2 c of the front panel 2. FIG. 10 shows a state immediately before the rear guard 6 is locked to the locking portion 10 of the back surface portion 2 c of the front panel 2.

  When the right end portion of the horizontal rail 6a is locked to the locking portion 10 of the back surface portion 2c of the front panel 2, the U-shaped portion 6a-1 at the right end portion of the horizontal rail 6a is first passed through the long hole 10a. The three U-shaped portions 6a-1 are passed through the corresponding long holes 10a substantially simultaneously.

  After passing the three U-shaped portions 6a-1 at the right end of the horizontal rail 6a through the corresponding long holes 10a, the rear guard 6 is lowered and the tip of the U-shaped portion 6a-1 is a locking hole. Position to face 10b. Then, the rear guard 6 is pulled obliquely rearward of the back surface of the main body 1 and the tip of the U-shaped portion 6a-1 is inserted into the locking hole 10b. This completes the locking of the right end of the cross rail 6a to the main body 1. This state is shown in FIG.

  Next, the configuration of the end plate 7a of the outdoor heat exchanger 7 with which the left end of the horizontal rail 6a of the rear guard 6 (the left side when viewed from the back when the rear guard 6 is attached to the main body 1) is engaged will be described. The outdoor heat exchanger 7 includes an end plate 7a having a substantially U-shape in plan view at the left end (left side when viewed from the back).

  A plurality of holes 7b are provided in a portion of the substantially U-shaped end plate 7a extending to the back side of the outdoor heat exchanger 7. The insertion part 6a-4 at the left end of the horizontal rail 6a of the rear guard 6 is inserted into the hole 7b.

  The distance between the locking portion 10 of the back surface portion 2c of the front panel 2 and the hole portion 7b of the end plate 7a of the outdoor heat exchanger 7 is longer than the length of the rear guard 6 (in a free state where no force is applied). It has become.

  Therefore, when inserting the insertion part 6a-4 of the left end part of the horizontal beam 6a of the rear guard 6 into the hole 7b of the end plate 7a of the outdoor heat exchanger 7, the bent part 6a-2 of the horizontal beam 6a of the rear guard 6; The rear guard 6 is pulled and extended in the direction in which the bending angle (α) of the bent portion 6a-3 increases (because the right end portion of the horizontal rail 6a is locked to the locking portion 10 of the back surface portion 2c of the front panel 2). , Apply force in the left direction using that as a fulcrum).

  FIG. 13 shows a state in which the insertion portion 6 a-4 at the left end portion of the horizontal rail 6 a of the rear guard 6 is inserted into the hole portion 7 b of the end plate 7 a of the outdoor heat exchanger 7. In this state, the rear guard 6 is attached by applying a pulling force, so that the pulling force is applied to the rear guard 6 and cannot be easily removed.

  Moreover, as shown in FIG. 7, the insertion part 6a-4 of the left end part of the horizontal rail 6a of the rear guard 6 is inclined 10-15 degrees downward with respect to the horizontal direction. Therefore, in a state where the insertion portion 6a-4 at the left end portion of the horizontal rail 6a of the rear guard 6 is inserted into the hole portion 7b of the end plate 7a of the outdoor heat exchanger 7, the insertion portion 6a-4 extends from the hole portion 7b. It is hard to come off.

  As shown in FIG. 14, the left end of the horizontal rail 6 a of the rear guard 6 is pressed by the side panel 3. On the side panel 3, pressing portions 3 c that press the left end portion of the lateral rail 6 a of the rear guard 6 are formed at three locations in the upper and lower sides. The side panel 3 is fixed to the hole 7b of the end plate 7a of the outdoor heat exchanger 7 with screws. At this time, since the pressing portion 3c of the side panel 3 presses the left end of the horizontal beam 6a of the rear guard 6 against the end plate 7a of the outdoor heat exchanger 7, the left end of the horizontal beam 6a of the rear guard 6 is securely fixed. Is done.
