Description

  The present invention relates to an air conditioner, and more particularly to improvement in workability during transportation and installation of an air conditioner including a blower fan that is elastically supported in a casing.

  Conventionally, an air conditioner called an air handling unit has been used (see, for example, Patent Document 1). In this apparatus, an air filter, a cold water coil, a hot water coil, a humidifier, and a blower fan are provided in a casing. The blower fan is fixed to a gantry, and the gantry is fixed to the casing via a vibration absorbing mechanism such as a laminated rubber or a spring.

  In such an air conditioner, if the vibration absorbing mechanism is excessively displaced by vibration during transportation, the blower fan or the like may be damaged. Therefore, when such an air conditioner is transported, it is common to restrict the displacement of the gantry by putting wood for fixing the gantry under the gantry during transportation.

The partition plate (70) has an opening (71) that is opened and closed by a door (80).
The fixing portion (90) can be fixed and released from the opening (71) .

In this configuration, since the fixing portion (90) is provided at the upper portion of the gantry (12), the gantry (12) can be fixed and released in a relatively wide place .

Further, in this configuration, the operator can put his / her hand through the opening (71) of the second partition plate (70) and can fix or release the gantry (12).

In addition, the second invention,
In the first invention,
The door (80) is in an open state when the gantry (12) is fixed at the fixing portion (90).

  In this configuration, when the forgery (12) is forgotten to be released, when the air conditioner is operated, the door (80) remains open, so that the blowing fan (7) does not allow normal blowing.

In addition, the third invention,
The first or second inventions to Oite,
The fixing part (90) is fixed to the casing (2) via a fixing jig (100).

  In this configuration, during transportation, the mounting jig (100) is used to fix the gantry (12).

In addition, the fourth invention is
In the second invention,
The fixing part (90) is fixed to the casing (2) via a fixing jig (100),
The door (80) is fixed in an open state by the fixing jig (100).

  According to the first invention, since the gantry can be fixed and released in a relatively wide place, the gantry can be easily fixed and released when the air conditioner is transported or installed.

In addition, according to the first invention, since the frame can be fixed or released from the opening, an extra work such as removing the panels on the front surface of the casing, for example, becomes unnecessary.

Further, according to the second invention, it is possible to confirm that the mount has been forgotten to be released by observing the open / closed state of the door. In addition, when forgetting to release the fixing of the gantry, normal blowing cannot be performed by the blowing fan, so that it can be easily noticed that the fixing jig is forgotten to be removed.

Further, according to the third invention, the gantry can be fixed and released easily by detaching the fixing jig.

Further, according to the fourth aspect of the invention, it is possible to confirm that the gantry has been forgotten to be released by visually checking the open / closed state of the door. In addition, when forgetting to release the fixing of the gantry, normal blowing cannot be performed by the blowing fan, so that it can be easily noticed that the fixing jig is forgotten to be removed.

In this example, the reinforcing member (72) provided on the second partition plate (70) is provided with a female screw (72a), and the through hole (100e) is provided with the fixing jig (100) as a reinforcing member. When attached to (72), it corresponds to the female screw (72a).

<Transportation and installation of air conditioner>
When transporting the air conditioner (1), the gantry (12) is fixed by the fixing jig (100). Specifically, first, the inspection door (80) is opened, and in this state, the flange (100f) of the fixing jig (100) is held on the gantry (12) while holding the door with the door fixing stay (100c). Place it on the jig fixing surface (12a). In this state, a knurled screw is passed through the through hole (100b), and the fixing jig (100) is fixed to the gantry (12) with the knurled screw. At this time, the operator puts his hand through the opening (71) of the second partition plate (70) and fastens the knurled screw.

  Next, the fixing jig (100) (specifically, the horizontal surface (100d)) and the reinforcing member (72) are fixed. Specifically, the operator passes the knurled screw through the through hole (100e) and fastens it to the female screw (72a) of the reinforcing member (72). This work is also performed by the operator putting his hand through the opening (71). Of course, the fastening order of the knurled screws is an example, and for example, the reinforcing member (72) may be fastened first.

  Through the above operation, the gantry (12) is fixed to the second partition plate (70) via the fixing jig (100). By fixing the gantry (12) in this way, even if vibration is applied to the air conditioner (1) during transportation of the air conditioner (1), the gantry (12) and the vibration absorbing mechanism (14) Displacement is regulated. Therefore, the blower fan (7), the vibration absorbing mechanism (14) and the like mounted on the gantry (12) are not damaged by vibration during transportation of the air conditioner (1).

  Then, after the transportation is completed, the fixing jig (100) can be removed. To remove the fixing jig (100), open the center front panel (2a) and put the hand through the opening (71) of the second partition plate (70). Remove the knurled screw securing (100). In other words, in the present embodiment, it is not necessary to remove the front panel (2a) of the fan chamber (S3) one by one when releasing the fixation of the gantry (12) (the blower fan (7)). Then, when the fixing jig (100) is removed, the fixing of the inspection door (80) by the door fixing stay (100c) is released, and the inspection door (80) can be closed.

<Effect in this embodiment>
As described above, in the present embodiment, since the fixing portion (90) is provided on the upper portion of the gantry (12), the blower fan (7) can be easily fixed and released. That is, compared with the conventional example in which work in a narrow space (especially work in the lower part of the casing) is forced, in this embodiment, efficiency in work such as transportation and installation is easily improved.

  In addition, the gantry (12) can be fixed or released through the opening (71) provided in the second partition plate (70), so that the front panel (2a ) Need not be removed one by one, and workability is improved in this respect as well. Also, since the pressure inside the fan chamber (S3) is higher than that in the heat exchange chamber (S2), it is important to ensure airtightness. In this embodiment, the front panel (2a) of the fan chamber (S3) is removed. There is no need to pay attention to airtightness during installation.

  Further, since the inspection door (80) cannot be closed unless the fixing jig (100) is removed, it is possible to prevent forgetting to remove the fixing jig (100). If the air conditioner (1) is operated with the fixing jig (100) forgotten to be removed, that is, with the inspection door (80) open, the fan chamber (S3 ) Pressure does not increase, the air volume from the outlet (22) decreases or becomes zero, and normal ventilation cannot be performed. Therefore, it is possible to easily notice that the fixing jig (100) is forgotten to be removed.

<< Other Embodiments >>
The fixing jig (100) is not essential. For example, a through hole for passing a fixing screw (for example, a knurled screw) is opened in the upper part of the gantry (12), and the gantry (12) is directly fixed to the second partition plate (70) or the like with a screw. You may do it. In this case, the screw through hole provided in the upper portion of the gantry (12) corresponds to the fixing portion (90).

  Also, the inspection door (80) is not essential. For example, when the inspection door (80) is not provided, the front panel (2a) may be removed and the gantry (12) (that is, the blower fan (7)) may be fixed or released. In this case, the front panel (2a) needs to be removed and attached, but the fixed part (90) is installed on the top of the base (12), so the fan (7) is fixed more than the conventional one. And can be easily released.
