Description

Reversible fan coil return air box

Technical Field

The utility model relates to a fan coil return air case that can commutate, it belongs to air conditioning equipment technical field.

Background

The effect that the return air case was its effect as the name implies is the return air, ordinary return air case is according to the requirement of air inlet direction, fix the sheet metal component on fan coil with the screw, the installation is accomplished the back, the air inlet direction is fixed promptly, if want to change the air inlet direction, must change another set of fan case, greatly increased the cost, change the degree of difficulty and change time, if want to do the adjustment on same set of fan case also can be because production technology is different, the mismatching of panel beating accessory leads to the adjustment failure, and only two simple iron plates are connected during ordinary fan case installation, after screwing up the screw, the phenomenon of a lot of unevenness can appear, the case hunches or sticks up the limit, influence the product pleasing to the eye, influence performance even.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides a reversible fan coil air return box.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a fan coil return air case that can commutate, includes the return air case, the return air case includes left side board, right side board, upper cover plate and movable plate, left side board and right side board are the axisymmetric structure, the upper cover plate is the same with movable plate structure.

Preferably, the upper side, the lower side and the front side of the left side plate and the right side plate are connected with the lapping plates towards the outer side, and the rear side of the left side plate and the right side plate is connected with the L-shaped lapping plates towards the outer side.

Preferably, the upper cover plate and the movable plate comprise a first lapping plate, a second lapping plate and a third lapping plate, and the first lapping plate and the third lapping plate are respectively connected to two sides of the second lapping plate.

Preferably, the included angle between the first lapping plate and the second lapping plate is 175 degrees, and the included angle between the third lapping plate and the second lapping plate is 90 degrees.

Preferably, the third lapping plate is also vertically connected with a positioning plate, and two ends of the connecting part of the positioning plate and the third lapping plate are provided with notches with the same width as the lapping plates.

Preferably, the return air box is made of sheet metal.

Compared with the prior art, the beneficial effects of the utility model are that: when changing the wind direction, need not change the fan case, only need adjust the position of movable plate can, the movable plate sets up to 175 degrees dog-ear structure, has guaranteed the planarization of installation, and because the panel beating material has elasticity, has the function of stiffening rib, still plays locking effect to the screw when solving perk limit and hunch limit.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a fan coil return air case that can commutate, includes return air case 1, return air case 1 includes left side board 2, right side board 3, upper cover plate 4 and portable board 5, left side board 2 and right side board 3 are the axisymmetric structure, upper cover plate 4 is the same with portable board 5 structure.

The outside of the last side of left side board 2 and right side board 3, lower side and preceding side is connected with overlap joint board 6, the outside of the side is connected with L shape overlap joint board 7 behind left side board 2 and the right side board 3.

Upper cover plate 4 and movable plate 5 include that lapping plate A8, lapping plate B9 and lapping plate C10, lapping plate A8 and lapping plate C10 connect respectively in the both sides of lapping plate B9.

The included angle between the first lapping plate A8 and the second lapping plate B9 is 175 degrees, and the included angle between the third lapping plate C10 and the second lapping plate B9 is 90 degrees.

The lap plate C10 is also vertically connected with a positioning plate 11, and two ends of the joint of the positioning plate 11 and the lap plate C10 are provided with notches with the same width as the lap plate 6.

The working principle is as follows:

when downward wind is required, the movable plate 5 is installed at the front side, see fig. 1. When it is necessary to supply air backward, the movable plate 5 is fixed to the lower side of the upper cover plate 4, see fig. 3. When reversing, the movable plate 5 is only needed to be disassembled and fixed on the lower side or the front side by screws. Be equipped with 175 contained angle on upper cover plate 4 and the movable plate 3, prevented that the phenomenon of back perk or hunch-up is accomplished in the installation, and the locating plate has guaranteed the mounted position of left side board 2 and right side board 3, realizes fixing a position fast.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
