JPH06174255A - Suction grille opening or closing type indoor device of air conditioner - Google Patents

Abstract

PURPOSE:To perform a stable opening or closing of a suction grille by a method wherein a resin washer is assembled between a four-element link fixing element and a shaft stopper ring. CONSTITUTION:One fixing element 4a of a four-element link 9 for use in opening or closing a suction grille 1 is fixed to the suction grille 1 and the other fixing element 4b is fixed to a front frame 3. Each of links 2a and 2b is connected to the fixing elements 4a and 4b, respectively. The fixing element 4b is provided with a crescent-shaped hole 7 at a circumferential position of a fulcrum point 6 with the link 2b. A shaft 5 is passed through the hole 7 and the fixing element 4b is held and fixed with the link 2b and a fixing ring 8. A resin washer 10 is assembled between the fixing element 4b and the stopper ring 8 so as to prevent the fixing element 4b from being contacted with the stopper ring 8. With such an arrangement as above, no contact with the fixing element caused by contact with the stopper ring 8 occurs when the suction grille 1 is opened or closed, resulting in that a stable opening or closing of the suction grille 1 can be attained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of a separate type air conditioner.

[0002]

2. Description of the Related Art Conventionally, in the indoor unit of this type of air conditioner, the mechanism for opening and closing the intake grill 1 as shown in FIGS. 3 and 4 has links 2a and 2b, the intake grill 1 and the front frame 3, respectively. It is composed of fixed four-contact link fixtures 4a and 4b.

Reference numeral 5 denotes a shaft, which is passed through a crescent-shaped hole 7 provided at a position on the circumference of a fulcrum 6 of the four-contact link fixture 4b and the link 2b. The contact link fixture 4b is sandwiched.

[0004]

However, with such a structure, when opening and closing the intake grill at the time of taking out and installing the air filter and the air cleaning filter,
Since the metal snap ring that moves in conjunction with the intake grill and the four-sided link fixing tool move while making contact, a "quick" sound is generated, and the four-sided link fixing axis There was a drawback that the sliding part of the item was abraded by rubbing and shortened the life of the opening and closing mechanism of the suction grill.

[0005]

In order to solve the above-mentioned problems, the present invention incorporates a resin washer between the four-contact link fixing device and the retaining ring of the shaft.

[0006]

The operation of the above means is as follows.

That is, since the resin washer is sandwiched between the four-contact link fixing tool and the retaining ring, the four-contact link fixing tool loses contact with the retaining ring when the intake grill is opened and closed. Wear is eliminated.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 is a suction grill. 9 is a suction grill 1
Is a four-sided link for opening and closing, and one of the fixing members 4a is fixed to the suction grill 1 and the other fixing member 4a.
b is fixed to the front frame 3.

A link 2 is attached to each of the fixtures 4a and 4b.
a and 2b are connected. The fixture 4b has a crescent-shaped hole 7 at a position on the circumference of a fulcrum 6 with the link 2b.
Is provided so that the shaft 5 is passed through the hole 7 and the fixing tool 4b is sandwiched between the link 2b and the retaining ring 8.

A resin washer 10 is incorporated between the fixing tool 4b and the retaining ring 8 so that the fixing tool 4b and the retaining ring 8 do not come into contact with each other.

[0012]

As described above, according to the present invention, since the resin washer is sandwiched between the fixing member and the retaining ring, when the air filter and the air cleaning filter are taken out and the suction grill is opened and closed at the time of mounting work. , The four-way link fixture that works in conjunction with the intake grill and the retaining ring on the shaft no longer come into contact with each other, and there is no "squeaking" noise.

Further, wear of the fixture due to contact of the retaining ring of the shaft is eliminated, and stable opening and closing of the intake grill can be obtained.
