Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall-mounted indoor unit of an air conditioner.
[0002]
[Prior art]
FIG. 3 is a perspective view showing a wall-hanging indoor unit of a conventional air conditioner partially cut away.
[0003]
A suction grill 2 is attached to the front surface of the main body 1 of the indoor unit, a filter 3 is disposed inside thereof, heat exchangers 5a and 5b are disposed inside thereof, and a flow-through fan 7 is disposed inside thereof.
Flaps 14a and 14b and a louver (not shown) are disposed at the air outlet 6 formed in the lower front portion of the main body 1.
[0004]
A drain pan 15 is installed below the heat exchangers 5a and 5b, and an electrical box 8 is installed on the side.
A main base 9 is disposed in the electrical box 8, and a sub-base 10 connected to the main base 9 via a lead wire 13 is detachably fastened to a front surface of a drain pan 15 by a screw 12.
[0005]
A part 11 that needs to be exposed to the front of the indoor unit such as a light-emitting lamp and a signal receiving amplifier of a remote controller is attached to the front surface of the sub-board 10.
[0006]
During the operation of the air conditioner, refrigerant from an outdoor unit (not shown) circulates in the heat exchangers 5a and 5b, and the once-through fan 7 is rotationally driven.
Then, indoor air is sucked into the main body 1 from the suction grill 2, and dust in the air is captured and removed in the process of flowing through the filter 3.
[0007]
Next, after cooling or heating by passing through the heat exchangers 5a and 5b, the heat exchanger 5a and 5b are energized by the through-flow fan 7, and then guided from the outlet 6 to the louvers and flaps 14a and 14b and blown out into the room. The
[0008]
[Problems to be solved by the invention]
In the conventional indoor unit, after the main base 9 is assembled in the electrical box 8, the sub-base 10 is fastened to the drain pan 15. When the main base 9 is assembled in the electrical box 8, the main base 9 is attached to the main base 9. Since the sub-board 10 is connected via the lead wires 13, not only is it difficult to incorporate the main board 9, but the sub-board 10 may collide with surrounding parts and be damaged.
[0009]
Further, since the sub-board 10 is fastened to the front surface of the drain pan 15 with the screw 12, there is a problem that this attachment takes time and effort.
[0010]
[Means for Solving the Problems]
The present invention has been invented to solve the above-mentioned problems, and the gist of the present invention is that a drain pan is installed below a heat exchanger installed in front of the inside of the main body and the heat exchanger side. An air conditioner is installed in which an electric box is installed, a main base is disposed in the electric box, and a sub-base connected to the main base via a lead wire is detachably attached to the front surface of the drain pan. In the wall-mounted indoor unit, the wall-mounted indoor unit for an air conditioner is provided with a storage space for storing the sub-board in a temporarily stored state in the electrical box.
[0011]
Another feature is that a mounting claw for mounting the sub-basement integrally therewith is formed in front of the drain pan.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention is shown in FIG. 1 and FIG. 2, FIG. 1 (A) is a perspective view showing a partially broken indoor unit, and FIG. 1 (B) is along the BB line of (A). Sectional drawing and FIG. 2 are sectional drawings of an electrical equipment box. As shown in FIG. 2, a storage space 18 for storing the sub-board 10 in a temporarily stored state is provided in the electrical box 8.
[0013]
As shown in FIGS. 1 (A) and 1 (B), mounting claws 17a and 17b are integrally formed on the front surface of the drain pan 15, and the sub-base 10 is mounted on the mounting claws 17a and 17b. It is attached by being pinched.
[0014]
In FIG. 1B, reference numeral 16 denotes a heat insulating material attached to the front and lower surfaces of the drain pan 15.
Other configurations are the same as those of the conventional one shown in FIG. 3, and the corresponding members are denoted by the same reference numerals and the description thereof is omitted.
[0015]
The electrical box 8 is stored in a state in which the main base 9 is fixed and the sub-base 10 is temporarily stored in the storage space 18. In this state, it is assembled at a predetermined position inside the main body 1 and fixed by a screw passing through the screw hole 19.
[0016]
Thereafter, the sub-board 10 is taken out from the storage space 18 of the electrical box 8 and attached to the front surface of the drain pan 15 by the mounting claws 17a, 17b.
[0017]
Since the electrical box 8 is stored with the sub-board 10 temporarily stored in the storage space 18 and is assembled to the indoor unit, the electrical box 8 can be easily stored and assembled, as in the conventional case. It is possible to prevent the sub-board 10 from colliding with surrounding parts and being damaged.
[0018]
Further, since the sub-base 10 can be fixed by being pushed between the mounting claws 17a and 17b, it can be easily fixed in a short time by one person.
[0019]
【The invention's effect】
In the present invention, due to the provision of storage space for storing a state of being provisionally housed sub base in electric box, and stored in a state in which the electrical component box sub foundation is temporarily accommodated in the accommodating space and, in this state Therefore, the storage and assembly work of the electrical box can be facilitated, and when the electrical box is assembled, the sub-board can be prevented from colliding with surrounding parts and being damaged as in the prior art.
[0020]
If an attachment claw for attaching the sub-base is formed integrally with the drain pan in front of the drain pan, the sub-base can be easily fixed in a short time by one person.
