Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outdoor unit of a separate type air conditioner, and more particularly to a mounting structure for an air outlet grill that is mounted opposite an air outlet on a front plate of a casing.

Generally, in the outdoor unit of a separate type air conditioner, a circular air outlet is provided on the front plate of the casing facing the air blowing fan inside the casing, while a plurality of spokes extending radially at equal intervals in the circumferential direction are provided. A circular outlet grill is provided, and the outlet grill is mounted to the front plate with screws so as to face the outlet (see Japanese Utility Model Publication No. 52-26270).

However, the above-mentioned conventional type has a drawback that the installation workability is poor because it is screwed. Therefore, as a mounting structure for the above-mentioned outlet grille, screw fixing parts that can be screwed to the front plate are provided at the tips of one or two spokes of the outlet grille, and locking parts are provided at the tips of each of the other spokes. At the same time, an engaging part capable of engaging with the above-mentioned engaging part is formed on the peripheral edge of the air outlet, and the engaging part of the spoke is engaged with each engaging part, and the screwed part of the spoke is secured to the front. It is conceivable that by attaching the outlet grille to the plate by screwing it, the outlet grille can be attached with fewer screws, thereby improving the installation workability.

However, in the above-mentioned model, since the locking part of the spoke is inserted and locked into the engaging part, its fixation is not reliable, and the air from the blow-off fan causes the blow-off grill to rattle and vibrate, causing noise. There is a problem that occurs.

Therefore, the present invention was made in view of this point, and the above-mentioned blowout grille is provided with auxiliary spokes whose tips abut against the front plate in addition to the conventional spokes (main spokes), and the auxiliary spokes and the main By installing the outlet grill in such a way that the spokes interact with each other in a direction that makes them lock or contact each other tightly, there is no need to increase the number of screw-fastening points.
The purpose of this invention is to increase the mounting strength of the outlet grille and prevent the outlet grille from rattling due to air from the outlet fan.

Therefore, the configuration of the present invention is to form two recesses facing each other in the diametrical direction of the circular air outlet on the peripheral edge of the circular air outlet provided on the front plate of the casing, and insert holes in the side walls of each of the recesses. and four main spokes extending radially at equal intervals in the circumferential direction; a circular outlet grille having at least four auxiliary spokes extending radially between each of the main spokes;
A locking portion that can be inserted and locked into the insertion hole is provided at each tip of a pair of main spokes extending in the diametrical direction of the outlet grille, and a locking portion that can be inserted and locked into the insertion hole is provided, and a screw is provided at each tip of the other pair of main spokes. A screw fixing part that can be screwed is provided in the hole, and a contact part that can come into contact with the front plate is provided at the tip of each of the auxiliary spokes, and each of the contact parts is pressed into contact with the front plate. In this state, the locking portions of the main spokes are inserted into the insertion holes and locked, and the screwed portions of the main spokes are screwed into the screw holes so that the outlet grille is mounted facing the outlet, As a result, the front plate is pulled towards you by the locking part or screwed part of the main spokes, while the front plate is pushed backward by the contact part of the auxiliary spokes located between the main spokes, and the blowout grille is tightly fixed to the front plate.
