JPH0650561A - Suction grill switching type indoor unit for air conditioner - Google Patents

Abstract

PURPOSE:To obtain safety at the time of opening a suction grill in the case of removing, mounting an air filter, an air cleaning filter by so forming a shape of a sliding unit of a link as to increase a friction, and holding a fixing fitting by a lever and a snap ring. CONSTITUTION:A shape of a sliding unit 4 of a fixing fitting 3a of a link 2a at a protrusion 5 is increased to slightly brake a rotation of the link 2a. On the other hand, a crescent shape hole 8 is formed at a position on a circumference of a fulcrum with the link 2b at the fitting 3a, a shaft 9 is inserted into the hole 8, and the fitting 3a is held by the link 2a and a snap ring 10 of the shaft 9. Thus, a suction grill is free and not closed, lateral fluctuations are eliminated, and a stable switching operation is obtained.

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 an indoor unit of an air conditioner of this type, as shown in FIGS. 4 and 5, the mechanism for opening and closing the intake grill 1 includes links 2a and 2b and a four-contact link fixture 3.
It is composed of a and 3b.

Reference numeral 4 denotes a sliding portion with respect to the protrusion 5 of the four-contact link fixing tool 3a, which has a shape with reduced friction so that the suction grill 1 can be opened and closed lightly.

The link 2b is a four-contact link fixing tool 3a.
And is connected at one point.

[0005]

However, in the case of such a structure, when the intake grill is opened at the time of taking out and attaching the air filter and the air cleaning filter, the friction between the link and the protrusion of the four-contact link fixing device is caused. Since the intake grill is small, the intake grill will be closed by the weight of the intake grill if you do not hold the intake grill by hand while locking the intake grill from the beginning. If you open it by holding the intake grill at a position that is off center, the left and right sides will not open at the same angle, and you will feel awkward.

Furthermore, the link and the four-contact link fixing device are 1
Since it was connected only by the points, the strength was weak, and there was a problem that rattling on the left and right of the intake grill was large when the intake grill was opened.

[0007]

In order to solve the above problems, according to the present invention, the shape of the sliding portion of the four-link link fixing tool of the link with respect to the projecting portion of the link is such that friction is increased, and the four-contact type is further provided. A crescent-shaped hole is provided on the circumference of a fulcrum with the link of the link fixing tool, and a four-contact link fixing tool is sandwiched between the link and the retaining ring of the shaft by passing the shaft through the hole.

[0008]

The operation of the above means is as follows.

That is, the friction of the sliding portion of the link is increased so that the suction grill is not closed by its own weight while the suction grill is locked from the beginning.

Further, by increasing the number of connections between the link and the four-sided link fixing tool at one place, the strength of the four-sided link is improved, and rattling on the left and right of the suction grill when the suction grill is opened is eliminated. .

[0011]

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

In FIG. 1, reference numeral 1 is a suction grill. 6
Is a four-contact link for opening and closing the suction grill 1, and one of the fixing members 3b is fixed to the suction grill 1.
The other fixture 3a is fixed to the front frame 7. Links 2a and 2b are connected to the fixtures 3a and 3b, respectively.

The fixture 3a is provided with a crescent-shaped hole 8 at a position on the circumference of a fulcrum with the link 2b, and a shaft 9 is passed through the hole 8 to form a link 2b and a retaining ring 10 of the shaft 9. It has a structure in which the fixture 3a is sandwiched.

In FIGS. 2 and 3, the shape of the sliding portion 4 of the link 2a with respect to the protrusion 5 of the fixture 3a is such that the friction is larger than that of the conventional one, and the rotation of the link 2a is slightly braked. ing.

[0015]

As described above, according to the present invention, since the sliding portion of the link is shaped to increase friction, when the intake grill is opened for taking out and attaching the air filter and the air cleaning filter, By slightly braking the movement of the suction grill, the suction grill will not close due to its own weight while the suction grill is locked from the beginning, and safe work can be performed.

Further, even when the suction grill is opened by holding a position deviated from the center in the longitudinal direction, the suction grill opens at the same angle on the left and right, and the feeling is improved.

Further, by sandwiching the fixing member between the lever and the retaining ring, the strength of the four-contact link is increased, and the rattling of the left and right of the suction grille is eliminated, so that stable opening and closing work can be obtained.
