Technical Field

The present invention relates to an installation method of indoor unit of air conditioner.

Background

As an indoor unit of a conventional air conditioner, there is a structure in which an indoor unit of an air conditioner is locked to an attachment plate attached to a wall and attached (see patent document 1). The indoor unit of the air conditioner is mounted by moving horizontally from the front of the mounting plate so as to be disposed close to the ceiling.

Documents of the prior art

Patent document

Patent document 1: japanese patent laid-open publication No. 2002-

In general, when an indoor unit is mounted on a wall, a work space needs to be secured between the indoor unit and the wall by inclining the indoor unit in order to connect a pipe drawn out from the wall to the indoor unit. However, in patent document 1, the connection work of the pipes is not taken into consideration, and when it is desired to install the indoor unit close to the ceiling, there is a possibility that the upper portion of the indoor unit collides with the ceiling when the conventional indoor unit is tilted.

Disclosure of Invention

The invention provides an installation method of an indoor unit of an air conditioner, which comprises the following steps: even when the indoor unit is installed close to the ceiling, the indoor unit can be prevented from colliding with the ceiling when the indoor unit is installed.

In accordance with the present invention, there is provided an installation method of an indoor unit of an air conditioner including a casing having a casing main body and a detachable member detachable from an upper portion or a side portion of the casing main body, the installation method including: the detachable member is attached to a wall surface in a state where the detachable member is detached from the housing body, and the detachable member is attached to the housing body attached to the wall surface.

According to the indoor unit of an air conditioner of the present invention, even when the indoor unit is installed near the ceiling, the indoor unit can be prevented from colliding with the ceiling by performing the installation work with the detachable member removed. For example, in the pipe connecting work, the work is performed in a state where the detachable member is removed, and therefore, even when the indoor unit is tilted, the indoor unit hardly collides with the ceiling, and therefore, a sufficient work space can be secured between the indoor unit and the wall surface, and the indoor unit can be prevented from colliding with the ceiling.

In one embodiment, in the method of mounting an indoor unit of an air conditioner, a height dimension of the casing to which the detachable member is mounted on the casing main body is larger than a height dimension of the casing main body.

The "height" may be a dimension in the vertical direction of each component in a state where the indoor unit is attached to the wall surface.

In the above embodiment, a part of the housing is constituted by a detachable member, and the height of the housing main body when the detachable member is detached is smaller than the height dimension of the housing to which the detachable member is attached. Therefore, even when the indoor unit is installed near the ceiling, the indoor unit can be effectively prevented from colliding with the ceiling by performing the mounting operation with the detachable member removed.

In one embodiment, the indoor unit includes a filter attached to at least an upper surface of the casing main body, and the attachment/detachment member includes a guide portion for guiding the filter.

According to the above embodiment, since the detachable member also has a function of guiding the filter, it is not necessary to provide an additional member for guiding the filter, and the number of members can be reduced.

In one embodiment, in a state where the detachable member is attached to the casing main body, an upper end of the filter is disposed between an upper end of the casing main body and an upper end of the detachable member.

According to the above-described embodiment, the upper end of the filter is disposed between the upper end of the casing main body and the upper end of the detachable member, and therefore, the filter is housed in the casing, and the indoor unit can be prevented from becoming large.

In one embodiment, in the method of mounting an indoor unit of an air conditioner, the casing includes a mounting plate for mounting the casing body to the wall surface, the casing body includes a hook portion provided on a rear surface facing the mounting plate, the mounting plate includes a receiving portion for hooking the hook portion of the casing body, and a dimension from a lower end of the hook portion of the casing body to an upper end of the attachment/detachment member is larger than a distance from the upper end of the receiving portion of the mounting plate to a ceiling in a state where the casing body is mounted to the wall surface via the mounting plate.

When an indoor unit is to be installed, in which the dimension from the lower end of the hook portion to the upper end of the indoor unit is greater than the distance from the upper end of the receiving portion of the installation plate to the ceiling, the upper end of the indoor unit collides with the ceiling, and the indoor unit cannot be installed on the wall surface. In contrast, according to the present invention, even when the distance from the lower end of the hook portion of the casing body to the upper end of the detachable member is longer than the distance from the upper end of the receiving portion of the attachment plate to the ceiling as in the above-described embodiments, the detachable member is detached and the indoor unit can be prevented from colliding with the ceiling.

In one embodiment, in a method of mounting an indoor unit of an air conditioner, a distance between an upper end of the casing main body and a ceiling is 30mm or more in a state where the casing main body is mounted to the wall surface via the mounting plate.

In one embodiment, in a state where the detachable member is attached to the casing body, a distance between an upper end of the detachable member and a ceiling is less than 30 mm.

According to the above embodiment, since the distance between the upper end of the detachable member and the ceiling is less than 30mm, when the indoor unit is mounted on the wall surface, the indoor unit can be integrated with the ceiling of the room, and the appearance of the indoor unit can be improved.

In one embodiment, in the method of mounting an indoor unit of an air conditioner, the attachment/detachment member is a ceiling grill provided over the entire length of the casing main body in the width direction.

In one embodiment, in the method of attaching an indoor unit of an air conditioner, the attachment/detachment member is a side plate that is detachably attached to both ends in the width direction of the casing main body.

Fig. 3 is a sectional view of the indoor unit 1 according to the present embodiment. Fig. 3 shows a cross section of the indoor unit 1 perpendicular to the left-right direction.

Referring to fig. 3, the indoor unit 1 according to the present embodiment includes an attachment plate 60 fixed to the wall surface Wa. The mounting plate 60 has a hook-shaped receiving portion 61, and the receiving portion 61 is provided at an upper end of the mounting plate 60 with a distal end bent upward.

Further, the case main body 20 of the present embodiment has a hook portion 21 having a tip bent downward. The hook 21 is provided on the upper portion of the rear surface of the case main body 20 facing the attachment plate 60. The indoor unit 1 is attached to the wall surface Wa by hooking the hook 21 of the casing body 20 to the receiving portion 61 of the attachment plate 60 fixed to the wall surface Wa.

In the present embodiment, in a state where the case main body 20 is attached to the wall surface Wa via the attachment plate 60, the vertical distance d1 from the lower end of the hook portion 21 of the case main body 20 to the upper end of the ceiling grid 30 is longer than the vertical distance d2 from the upper end of the receiving portion 61 of the attachment plate 60 to the ceiling. On the other hand, in a state where the case body 20 is attached to the wall surface Wa via the attachment plate 60, the vertical distance d3 from the lower end of the hook portion 21 of the case body 20 to the upper end of the case body 20 is shorter than the vertical distance d2 from the upper end of the receiving portion 61 of the attachment plate 60 to the ceiling. In the present embodiment, the vertical distance d4 between the ceiling grid 30 and the ceiling Ce is about 10 mm. In the present embodiment, the vertical distance d5 between the casing main body 20 and the ceiling Ce is 30mm or more.

In the present embodiment, the height dimension (dimension in the vertical direction) H1 of the housing 10 to which the top surface grill 30 is attached is larger than the height dimension H2 (dimension in the vertical direction) of the housing main body 20.

The upper surface portion 22 of the housing main body 20 includes a flat portion 22a extending in a direction intersecting the vertical direction, and an inclined portion 22b provided continuously with the tip of the flat portion 22a and inclined downward toward the front. Thus, the height dimension H3 of the case main body 20 at the front end portion of the inclined portion 22b is smaller than the height dimension H2 of the entire case main body 20.

In a state where the top grill 30 is attached to the housing main body 20, the upper end of the filter 50 of the present embodiment is disposed between the upper end of the housing main body 20 and the upper end of the top grill 30.

(mounting method)

Next, an installation method of the indoor unit 1 according to the present embodiment will be described with reference to fig. 5 to 8. The method of installing the indoor unit 1 of the present embodiment includes: the case body 20 is attached to the wall surface Wa, and the ceiling grid 30 is attached to the case body 20 attached to the wall surface Wa.

Fig. 5 is a cross-sectional view of the indoor unit 1 when the indoor unit 1 according to the present embodiment is attached to the attachment plate 60. Fig. 6 is a sectional view of the indoor unit 1 during the pipe connection operation. Fig. 5 and 6 show cross sections of the indoor unit 1 in a plane orthogonal to the left-right direction. Fig. 7 is a schematic perspective view of the case main body 20 of the present embodiment when the top surface grill 30, the front surface panel 40, and the filter 50 are attached. Fig. 8 is a flowchart of an installation method of the indoor unit 1 according to the present embodiment.

First, as shown in fig. 5, the mounting plate 60 is mounted on the wall surface Wa (step S1 in fig. 8). The mounting plate 60 is fixed to the wall surface Wa by screws or the like. At this time, the mounting plate 60 is fixed to the top surface grill 30 (shown in fig. 1) of the casing 10 at a position separated from the ceiling Ce by about 10 mm.

Next, the case main body 20 is attached to the attachment plate 60 (step S2 in fig. 8). Specifically, the housing body 20 is moved from the front toward the attachment plate 60 (see the arrow in fig. 5), and the hook portion 21 of the housing body 20 is hooked on the receiving portion 61 of the attachment plate 60.

As shown in fig. 5, the housing main body 20 is attached to the attachment plate 60 in a state where the top surface grill 30, the filter 50, and the front panel 40 (shown in fig. 1) are removed from the housing main body 20. In other words, the casing main body 20 is attached to the attachment plate 60 while the height dimension of the indoor unit 1 is suppressed. In a state where the case main body 20 is attached to the wall surface Wa via the attachment plate 60, a distance between an upper end of the case main body 20 and the ceiling Ce is 30mm or more.

At this time, since the vertical distance d3 from the lower end of the hook 21 of the housing body 20 to the upper end of the housing body 20 is shorter than the distance d2 from the upper end of the receiving portion 61 of the attachment plate 60 to the ceiling, the housing body 20 is attached to the attachment plate 60 without the upper portion of the housing body 20 coming into contact with the ceiling.

If the case body 20 is attached to the attachment plate 60 in a state where the top surface grill 30 (indicated by a two-dot chain line in fig. 5) is attached to the case body 20, the top surface grill 30 interferes with the ceiling Ce, and the case body 20 cannot be attached to the attachment plate 60.

Then, as shown in fig. 6, the case main body 20 is tilted with respect to the attachment plate 60 (see the arrow in fig. 6), and the refrigerant pipe 72 and an external refrigerant pipe are connected to each other while a working space is secured between the case main body 20 and the wall surface Wa (step S3 in fig. 8) (step S4 in fig. 8). In the state shown in fig. 6, the housing main body 20 does not interfere with the ceiling Ce.

If the housing main body 20 is tilted in a state where the ceiling grille 30 (indicated by a two-dot chain line in fig. 6) is attached to the housing main body 20, the ceiling grille 30 interferes with the ceiling Ce, and a sufficient working space cannot be secured.

Finally, as shown in fig. 7, the tilt of the case main body 20 is returned to the original state (step S5 in fig. 8), and the ceiling grille 30, the filter 50, and the front panel 40 are attached to the case main body 20 attached to the wall surface Wa in this order from the front (see the arrows in fig. 7) (step S6 in fig. 8). Specifically, first, the top grill 30 is attached to the housing main body 20 from the front. Then, the filter 50 is inserted along the

guide rails

31a, 32a, 35b (shown in fig. 4) of the top surface grill 30 and is attached to the top surface grill 30. Finally, the front panel 40 is attached to the housing main body 20 from the front.

In the present embodiment, in a state where the top surface grill 30 is mounted to the casing main body 20, a distance between an upper end of the top surface grill 30 and the ceiling Ce is less than 30 mm. Specifically, in the present embodiment, as described above, the distance between the upper end of the top surface grill 30 and the ceiling Ce is about 10mm in the state where the top surface grill 30 is attached to the housing main body 20.

The method of mounting the indoor unit 1 of the air conditioner according to the present embodiment exhibits the following operational advantages.

Even when the indoor unit 1 is installed near the ceiling Ce, the indoor unit 1 can be prevented from colliding with the ceiling Ce by performing the installation work with the ceiling grill 30 removed.

If the case body 20 is attached to the attachment plate 60 in a state where the top surface grill 30 (indicated by a two-dot chain line in fig. 5) is attached to the case body 20, the top surface grill 30 interferes with the ceiling Ce, and the case body 20 cannot be attached to the attachment plate 60. In contrast, in the mounting work of mounting the casing main body 20 to the mounting plate 60, the top grill 30 is removed and the casing main body 20 can be mounted to the mounting plate 60 while suppressing the indoor unit 1 from colliding with the ceiling Ce.

If the housing body 20 is tilted in a state where the ceiling grille 30 (indicated by two-dot chain lines in fig. 6) is attached to the housing body 20, the ceiling grille 30 interferes with the ceiling Ce, and a sufficient working space for the connection work of the pipes cannot be secured between the housing body 20 and the wall surface Wa. In contrast, in the connection operation between the refrigerant pipe 72 and the external refrigerant pipe, the ceiling grill 30 is removed and the operation is performed, whereby a sufficient operation space is ensured between the casing body 20 and the wall surface Wa, and the indoor unit 1 is prevented from colliding with the ceiling Ce (see fig. 6).

A part of the housing 10 is constituted by the detachable top grill 30, and a height H2 of the housing main body 20 when the top grill 30 is removed is smaller than a height H1 of the housing 10 to which the top grill 30 is attached. Thus, even when the indoor unit 1 is installed near the ceiling Ce, the indoor unit 1 can be effectively prevented from colliding with the ceiling Ce by removing the ceiling grill 30 to perform the work.

In addition, since the upper end of the filter 50 is disposed between the upper end of the casing main body 20 and the upper end of the top grill 30 in the state where the top grill 30 is attached to the casing main body 20, the filter 50 is housed in the casing 10, and the indoor unit 1 can be prevented from being large-sized.

When the indoor unit 1 is attached to the wall surface Wa in a state where the ceiling grill 30 is attached to the casing body 20, a space of about 30mm is required between the upper portion of the indoor unit 1 and the ceiling Ce. In contrast, even when the distance between the upper portion of the indoor unit 1 and the ceiling Ce is about 10mm as in the present embodiment, the indoor unit 1 can be attached to the wall surface Wa while suppressing collision of the indoor unit 1 with the ceiling Ce by performing the operation by removing the ceiling grill 30. That is, in the installation work of the indoor unit 1, the degree of freedom in installing the indoor unit 1 to the wall surface Wa can be increased by performing the work of removing the ceiling grill 30, and the indoor unit 1 can be disposed close to the ceiling Ce.

In addition, in the present embodiment, since the distance d4 between the upper end of the casing main body 20 and the ceiling Ce is about 10mm, when the indoor unit 1 is attached to the wall surface Wa, the indoor unit 1 and the ceiling Ce are integrated, and the appearance of the indoor unit 1 can be improved.

Since the top grill 30 includes the

guide rails

31a, 32a, 35a, and 35b for guiding the filter 50, it is not necessary to additionally provide a member for guiding the filter 50, and the number of members can be reduced.

Since the top grill 30 can be attached to and detached from the housing main body 20, maintenance of the top grill 30 can be easily performed.

Referring to fig. 11, in the present embodiment, in a state where the case main body 120 is attached to the wall surface Wa via the attachment plate 60, a vertical distance d1 from the lower end of the hook portion 21 of the case main body 120 to the upper end of the side plate 132 is greater than a vertical distance d2 from the upper end of the receiving portion 61 of the attachment plate 60 to the ceiling. On the other hand, in a state where the case main body 120 is attached to the wall surface Wa via the attachment plate 60, the vertical distance d3 from the lower end of the hook portion 21 of the case main body 120 to the upper end of the case main body 120 is shorter than the vertical distance d2 from the upper end of the receiving portion 61 of the attachment plate 60 to the ceiling. In the present embodiment, the distance d4 between the

side plates

131 and 132 and the ceiling Ce is about 10 mm.

In the present embodiment, a height dimension (a dimension in the vertical direction) H1 of the housing 110 to which the side plate 132 is attached is larger than a height dimension H2 (a dimension in the vertical direction) of the housing main body 120.

Fig. 12 is a sectional view taken along line XII-XII of fig. 11. In fig. 12, the blower 70 and the heat exchanger 71 are not shown.

Referring to fig. 12, a guide rail 131a for guiding the filter 150 is provided at a left side portion of the side plate 131. Similarly, a guide rail 132a for guiding the filter 150 is provided on the right side of the side plate 132.

Both ends of the filter 150 in the left-right direction are guided by a guide rail 131a provided on the side plate 131 and a guide rail 132a provided on the side plate 132, respectively, and the filter 150 is fitted into the side plate 131 and the side plate 132. The filter 150 is held by the guide rail 131a provided on the side plate 131 and the guide rail 132a provided on the side plate 132 in a state of being fitted into the side plate 131 and the side plate 132.

The method of attaching the indoor unit 1 according to embodiment 2 is the same as that according to embodiment 1 until the refrigerant pipe 72 is connected. In the present embodiment, after the connection operation of the refrigerant pipe 72 is completed, the

side plates

131 and 132 are attached from the front to the case main body 120 attached to the wall surface Wa. Then, the filter 150 and the front panel 40 are attached in this order of the filter 150 and the front panel 40 (see the arrow in fig. 10).

In embodiment 2, the same operational effects as those in embodiment 1 are exhibited.

In embodiment 2, since

side plates

131 and 132 individually form side surfaces on both sides of case 110 in the left-right direction, the parting line between the components is not exposed when viewed from the side surface. As a result, when the indoor unit 101 is viewed from the side, the appearance is fresh, and the appearance can be improved.

While the embodiments have been described above, it is to be understood that various changes in form and details may be made therein without departing from the spirit and scope of the appended claims.
