Abstract

PURPOSE:To finish the titled air conditioner unit of low cost and strong and with a large capacity, to have a good outward appearance by a method wherein an outer plate of the unit is made strong and only a conspicuous part of the outer plate is covered with a decorated material. CONSTITUTION:The frame of the unit 6 is formed of the outer plate 1 made by bending a sheet metal in the shape of U so as to have a sufficient strength and right and left support plates 5a and 5b. Then a fan casing 11, a motor 12, crossflow fans 13a and 13b, bearings 19a and 19b, a heat exchanger 14 and a drain pan 16 are incorporated into the frame in sequence and an auto-louver 17 and flaps 18a and 18b are fixed to the frame. Further, a bottom plate 8 and right and left side plates 7a and 7b for dressing are screwed into the frame, a ventilating grill 9 for dressing is attached to the frame and a filter 21 is mounted on the grill.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a housing structure of a wall-mounted air conditioning unit installed on a high wall indoors.

(b) The casing of the conventional wall-mounted air conditioner is made of thick sheet metal or synthetic resin covering the flat plate-like pace part and core part that support heavy objects such as the heat exchanger and the blower, and a decorative cover. were made of thin synthetic resin material. Such a structure is suitable for air conditioners of about 1 to 1.5 horsepower that can be integrally molded with a mold, but it is suitable for air conditioners of about 2, 5 to 3 horsepower that have increased heat exchange capacity. The shape was thick (as a result, the strength of the base part was poor), and molding costs were high and molding was difficult in order to integrally mold a box-shaped decorative cover.

(c) Purpose of the Invention The present invention provides strength to the exterior plate itself, and covers only the easily visible parts of the exterior plate with decorative members.
This is an inexpensive, strong, large-capacity, wall-mounted air conditioning unit that is manufactured with an attractive finish.

(B) Structure of the Invention The present invention provides an exterior plate in which a top surface, a back surface, and a bottom surface are integrally formed by bending a single sheet metal material into a substantially U-shape, and is fixed across these three surface portions. The unit consists of a pair of left and right support plates that support the heat exchanger, a pair of side plates that close off the skeleton of the unit body, a bottom plate that covers the bottom part, and a ventilation grill that is attached to the front opening of the exterior plate. It is designed to form a decorative surface portion of the main body.

(E) Embodiment To explain based on FIGS. 1 and 2, (1) is made by bending a single sheet metal material into a substantially U-shape.
), an exterior plate integrally formed with the bottom part (4), and a pair of left and right support plates (5a) (5b) fixed by spot welding across the three sides (21 (3) (4)). This forms the skeleton of the unit body (6).

(7a) and (7b) are a pair of side plates that close the openings on both left and right sides of the exterior plate (1), (8) is a bottom plate that covers the bottom part (4), and (9) is the front surface of the exterior plate (1). A plurality of ventilation grilles attached to the opening are each molded from a synthetic resin material to form a decorative surface portion of the unit body (6).

(10) is a glass wool insulation material pasted from the top part (2) to the upper half of the back part (3), and 01) is the bottom part (4) from the lower half of the back part (3). ), (12 is a coaxial electric motor axially connected to the left and right cross flow fans (13a) (13b), (141 is a left and right tube plate (15a) (15b)
) are the support plates (5a) (5b) K, the heat exchanger to be attached, (16) is the drain pan suspended from the heat exchanger, α
η is an auto louver that automatically changes the blown air to the left and right, (18a) and (18b) are flaps that change the blown air forward and diagonally downward, (19a and 19b) are support plates (5a) ( Cross flow fans (13a) (13b) attached to the outside of the through holes (20a) (20b) of
), (2+) is a plurality of air filters that are inserted and removed along the rear of the ventilation grille (9), and the grille is fixed to the interior wall surface (c), and the hook H on the exterior plate (1) is engaged. It is a wall hanging board.

The upper edge (c) of the ventilation grill (9) is connected to the exterior plate (1).
) to the front edge uneven part (A) of the top surface part (2).
5), and the lower edge (c) is the drain pan α6)
The unit body (6
) so that they can be attached in continuous juxtaposition.

As described above, there is an exterior plate (1) which is made of a sheet metal material bent into a substantially U-shape to provide its own strength, and a pair of left and right support plates (5a) (5b) that reinforce this exterior plate. After forming the frame of the perch unit body (6), the fan casing 01
), electric motor 02), cross flow fan (13a) (1
3b), bearings (19aX19b), heat exchanger I, drain pan Q6) and other equipment are installed in sequence, and the autolouver 07) and flaps (18a) and (18b) are attached.

After that, the bottom plate (8) is fixed with the screws (30), and the pair of left and right side plates (7a, 7b) are attached to the cross-sectional surface (31a) of the exterior plate (1).
) (31b), and then attach the ventilation grill (9) and the air filter (21) as described above to complete the assembly work. Once this finished product is installed as shown in Figure 1, cross flow fans (13a) (13b)
) by ventilation grill (9), air filter (21)
) After the indoor air is sequentially drawn in through the heat exchanger αa and cooled or heated, the airflow direction is changed to the desired direction by the autoroots <- (I7) and the flaps (18a) and (18b), thereby cooling or heating the room. Heated.

(F) Effects of the Invention According to the present invention, there is an exterior plate which is made of a single sheet metal material bent into a substantially U-shape to provide its own strength, and a pair of left and right supports that supplement the strength of this exterior plate. A strong skeleton of the unit body can be easily formed with the three parts including the plate, and the openings on the front and left and right sides of the exterior plate, which are easily visible when installed at a high place, have decorative ventilation grills on the left and right sides. Since decorative bottom plates are attached to the side plates and the bottom of the exterior plate, the appearance is good, and these decorative plate members can have simple shapes, so synthetic resin gold is used. It is possible to obtain a large-capacity wall-mounted air conditioning unit that is inexpensive, strong, and easy to mold.
