The present invention relates to an air-conditioning apparatus.
Conventionally, there has been an air-conditioning apparatus including an indoor unit composed of a front surface panel and a unit body (for example, see Patent Literature 1). In the air-conditioning apparatus described in Patent Literature 1, a recessed portion provided in the front surface panel and an engagement claw provided in the unit body engage with each other, so that the front surface panel is mounted to the unit body, and the front surface panel is thereby prevented from falling.
Patent Literature 1: Japanese Patent Laid-Open No. 9-112948 ([0119] to [0121], FIG. 11)
In the air-conditioning apparatus described in Patent Literature 1, when an engagement allowance between the front surface panel (a frame body) and the unit body (a base body) is reduced, an engagement state between the front surface panel and the unit body can be easily released, for example, at the time of maintenance, while the engagement state between the front surface panel and the unit body is not firm.
Also, in the air-conditioning apparatus described in Patent Literature 1, when the engagement allowance between the front surface panel (the frame body) and the unit body (the base body) is increased, the engagement state between the front surface panel and the unit body becomes firm, while the engagement state between the front surface panel and the unit body cannot be easily released, for example, at the time of maintenance.
In the air-conditioning apparatus described in Patent Literature 1, since it is not possible to easily release the engagement state between the front surface panel and the unit body while making firm the engagement state between the front surface panel and the unit body, there is a problem that operability is poor.
The present invention has been made based on the aforementioned problem, and an object thereof is to provide an air-conditioning apparatus with good operability.
An air-conditioning apparatus according to the present invention includes a main body including a frame body and a base body provided on a back surface side of the frame body, a frame body-side engagement section and an extension section that extends backward on both sides of the frame body-side engagement section are provided on a back side of the frame body, a base body-side engagement section that engages with the frame body-side engagement section, and a support base that is located below the extension section are provided on a front side of the base body, and when the frame body is mounted to the base body, the frame body-side engagement section and the base body-side engagement section engage with each other, and the extension section is supported by the support base.
In accordance with the present invention, when the frame body is mounted to the base body, the frame body-side engagement section and the base body-side engagement section engage with each other, and the extension section is supported by the support base. Thus, it is possible to easily release an engagement state between the frame body and the base body while ensuring an engagement allowance. Therefore, the air-conditioning apparatus with good operability can be obtained.

In a state in which the frame body 2 is attached to the base body 3, the frame body-side engagement section 2a and the base body-side engagement section 3a engage with each other as shown in
The frame body 2 is fixed to the base body 3 by attaching the frame body 2 to the base body 3 by use of a member such as a screw (not shown) at a lower portion of the frame body 2 and a lower portion of the base body 3 in a state in which the frame body-side engagement section 2a and the base body-side engagement section 3a engage with each other as shown in
In the following, (a) a procedure for removing the frame body 2 from the base body 3, and (b) a procedure for mounting the frame body 2 to the base body 3 are described by using
(a) Procedure for removing the frame body 2 from the base body 3
First, the frame body 2 is inclined by lifting a front surface side of the frame body 2 in a state in which the frame body 2 is mounted to the base body 3 as shown in
(b) Procedure for mounting the frame body 2 to the base body 3
First, the frame body 2 is inclined by lifting the front side of the frame body 2. Subsequently, the frame body 2 is pushed into the base body 3 in a state in which the frame body 2 is moved such that the frame body-side engagement section 2a and the extension section 2b are located between the base body-side engagement section 3a and the support base 3b (a direction of a dotted arrow in
As described above, the air-conditioning apparatus 100 according to the present embodiment includes the main body 1 including the frame body 2 and the base body 3 provided on the back surface side of the frame body 2, the frame body-side engagement section 2a and the extension section 2b that extends backward on the both sides of the frame body-side engagement section 2a are provided on the back side of the frame body 2, the base body-side engagement section 3a that engages with the frame body-side engagement section 2a, and the support base 3b that is located below the extension section 2b are provided on the front side of the base body 3, and when the frame body 2 is mounted to the base body 3, the frame body-side engagement section 2a and the base body-side engagement section 3a engage with each other, and the extension section 2b is supported by the support base 3b.
As described above, when the frame body 2 is mounted to the base body 3, the frame body-side engagement section 2a and the base body-side engagement section 3a engage with each other, and the extension section 2b is supported by the support base 3b. Thus, the engagement allowance can be ensured, and the air-conditioning apparatus 100 in which the frame body 2 and the base body 3 are in a firm engagement state can be obtained.
Also, for example, at the time of maintenance of the air-conditioning apparatus 100, the engagement state between the frame body 2 and the base body 3 can be released by rotating the frame body 2 with the support base 3b as a fulcrum. Thus, the engagement state between the frame body 2 and the base body 3 can be easily released.
Therefore, the air-conditioning apparatus 100 with good operability can be obtained.
Also, the inclined surface 2a11 is provided in the frame body-side engagement section 2a. Therefore, even if the frame body 2 and the base body 3 come into contact with each other while the frame body 2 is being pushed into the base body 3 in a case in which the frame body 2 is mounted to the base body 3, the frame body 2 and the base body 3 are less likely to be damaged.
Also, the inclined surface 3a11 is provided in the base body-side engagement section 3a. Therefore, even if the frame body 2 and the base body 3 come into contact with each other while the frame body 2 is being pushed into the base body 3 in a case in which the frame body 2 is mounted to the base body 3, the frame body 2 and the base body 3 are less likely to be damaged.
Also, the inclined surface 3b11 is provided in the support base 3b. Therefore, when the frame body 2 is mounted to the base body 3, the support base 3b guides a direction in which the frame body 2 is pushed, and when the frame body 2 is removed from the base body 3, the support base 3b guides a direction in which the frame body 2 is removed. Accordingly, the air-conditioning apparatus 100 with good operability can be obtained.
Note that an inclination angle of the inclined surface 3b11 of the support base 3b is desirably configured to match an inclination angle of the frame body 2 when the frame body 2 is removed. Accordingly, the operation of mounting the frame body 2 to the base body 3 can be facilitated, and the operation of removing the frame body 2 from the base body 3 can be facilitated. Therefore, the air-conditioning apparatus 100 with good operability can be obtained.
Note that the inclined surface 2a11 corresponds to a “first inclined surface” in the present invention.
Also, the inclined surface 3a11 corresponds to a “second inclined surface” in the present invention.
Also, the inclined surface 3b11 corresponds to a “third inclined surface” in the present invention.
