Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fixing device for a wall-mounted indoor unit in a separate air conditioner.

Conventional Structure and Problems Conventionally, a wall-mounted indoor unit has been fixed to a wall using the method shown in FIG. The main body 1 of the wall-mounted indoor unit has an inlet 2, an outlet 3, a heat exchanger 4, a drain pan 5, and a syringe fan 6. A latch 7 is attached to the upper part of the back panel 1a of the main body 1 by spot welding or screwing.
is fixed. On the other hand, a mounting plate 8 is fixed to the wall 9, and a hook-shaped fixture 10 is fixed to the lower part of the mounting plate 8 by spot welding or screwing. A hook-shaped recess 12 provided on the lower surface 1b of the main body 1 and the fixing fitting 10 are fastened together with a fixing screw 11. In the figure, 13 is a gas pipe led out from the heat exchanger 4 and housed in an auxiliary piping space 13a for connection to an outdoor unit (not shown), and 14 is a liquid pipe.

Conventionally, when the installation plate 8 is fixed to the wall 9, the uppermost end of the installation plate 7 is inserted into the hook 7 to hang it, and a hook-shaped fixing is done at the bottom. Metal fitting 10 and bottom surface 1 of main body 1
Align the recess 12 provided in b, and tighten the fixing screw 1.
It is fixed at 1.

However, in this conventional method, fixing the hook-shaped fixture 10 and the recess 12 largely occupies both ends of the area provided as the auxiliary piping space 13a below the rear panel 1a, and During piping, piping construction is difficult,
Furthermore, the hook-shaped fixture 10 and the installation plate 8 must be fixed with screws or spot welding, which is disadvantageous in terms of manufacturing man-hours.

Purpose of the invention The present invention solves the above-mentioned conventional drawbacks, and aims to provide a wider auxiliary piping space and facilitate piping work.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a through hole in the lower piece of the installation plate on which the main body of the indoor unit is hung, and also includes a fixture provided with a protrusion that fits into the through hole. , this fixing device includes a clamping part that is inserted into the installation plate, a body part that is gently bent downward, and a locking part that is fixed to a recess provided on the lower surface of the indoor unit body at a position below the body part. In the rear panel of the indoor unit main body, the piping space provided below the outside is widened by the fixture having the gently curved body, and the main body is fixed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 2 to 4. In the figure, reference numeral 15 denotes the main body of the wall-mounted indoor unit, which has an inlet 16 provided on the front panel side, an outlet 17, a heat exchanger 18, a drain pan 19, and a cross flow fan 20.
A hanging bracket 21 is fixed to the upper part of the back panel 15a of the main body 15 by spot welding or screws, while a flat plate-shaped installation plate 22 is fixed to the wall 23 (or the mounting frame) by screws. are doing.
At the top of the installation plate 22, there is provided an upper end portion 24 that is slightly bent and on which the hook 21 is hung.

Reference numeral 25 denotes a fixture made of a resin molded product, and the upper end of the fixture 25 engages with the lower end of the installation plate 22, and the lower end of the fixture 25 engages with the lower surface 15b of the main body 15. There is.

Reference numeral 26 in the figure is an auxiliary piping space provided outside and below the rear panel 15a, where the gas pipe 27 and liquid are led out from the heat exchanger 18 and connected to an outdoor unit (not shown). The tube 28 is housed long in the lateral direction.

In FIG. 3, the lower part of the installation plate 22 is
A bent portion 29 is provided, and a lower piece 30 is provided. This lower piece 30 is provided with through holes 31 and 32.
Above the fixture 25 made of the resin molded product described above, there are projecting pieces 33, 34;
a protrusion 35 that fits into the through holes 31 and 32;
There are 36. A clamping portion 37 is formed between the protruding pieces 33 and 34 and protrudes from the surface of the protruding pieces 33 and 34, and the lower piece 3 of the installation plate is attached to the tip of the clamping portion 37.
An inclined surface 38 is provided for leading when inserting into the 0. The fixture 25 has a body portion 39 that is gently bent downward from the upper portion, and ribs 40 for auxiliary use are provided at both ends of the body portion 39. Further, locking parts 41 are provided at both lower ends of the fixture 25, and screws 43, 44 are provided.
The lower surface 1 of the main body 15 of the indoor unit has a pilot hole 42 for
It is designed to be tightened together with a recess 45 (FIG. 2) provided in 5b.

Note that these fixtures 25 are provided at both ends of the installation plate 22.

In the above configuration, after the installation plate 22 is fixed to the wall 23, the clamping part 3 of the fixture 25 is placed below the installation plate 22.
7 and the protruding pieces 33 and 34, the lower piece 30 of the installation plate is forcibly inserted. By this insertion, the protrusions 35 and 36 fit into the through holes 31 and 32 to prevent them from coming off downward, and the elasticity of the resin of the clamping part 37 allows them to be sandwiched between the lower piece 30 and securely held. be done. From this state, hang the latch 21 of the indoor unit main body 15 on the upper end 24 of the installation plate 22, place the recess 45 against the locking part 41 of the fixture 25 at the bottom of the main body, and tighten the screws 43 and 44 to tighten the recess 45.
and the locking part 41 together, and the main body 15 of the indoor unit
This is to fix the Therefore, in this fixed state, the fixture 25 is attached to the lower piece 30 of the installation plate 22.
By providing the body portion 39 that is more gently curved over the lower surface 15b of the main body 15, the auxiliary piping space 26 can be made wider.

Effects of the Invention As described above, the present invention has a fixture that is provided with a through hole in the lower piece of the installation plate and a protrusion that fits into the through hole. A holding part, a body part that gently bends downward from this part, and a locking part that fixes to a recess provided on the lower surface of the indoor unit main body are provided below this body to widen the auxiliary piping space for storing auxiliary piping. Since the fixing device for the indoor unit body is made as shown in FIG. In addition, since the installation plate and the fixture are connected in a one-touch manner, unlike conventional fixation using spot welding or screws, the number of man-hours required for manufacturing the installation plate is reduced. It is something.
