Abstract

PURPOSE:To improve an external appearance of a state that a suction grill is opened by eliminating a warpage of the grill in the case of defrosting at the time of heating operation. CONSTITUTION:A plurality of ribs 7 are provided longitudinally on a rear surface of a suction grill 2, upper ends of the ribs 7 are connected, a heat insulator 8 is disposed to form an air layer 9, and a change due to heat is reduced to increase its strength. The insulator 8 is made of a resin series material having rigidity to further increase its strength, switching feeling of the grill 2 is improved, and an external appearance of a state that the grill 2 is opened is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to increasing the strength and heat insulation of a suction grill provided in front of a heat exchanger.

[0002]

2. Description of the Related Art Conventionally, an intake grill of this type of air conditioner has a structure as shown in FIGS.

In FIGS. 3 and 4, reference numeral 9 denotes an underframe main body of the air conditioner, which constitutes a makeup grill with an oblique suction bar 10a, and the suction grill 10 having the heat insulating material attached to the back and the suction grill 10. A front grill 11 is attached so that it can be opened and closed. A blower 12 and a heat exchanger 13 are arranged inside the front grill 11.

The intake grill 10 includes a catch 14 provided at the center of the front grill 11 on the lower front side, catches 14b provided at the lower ends of both ends, and a knob 15 provided at the center of the lower back of the intake grill 10. It is fixed by the knobs 15b provided at the lower ends of both ends.

[0005]

However, in such a structure, the temperature of the heat exchanger 13 becomes low during the defrosting operation during heating, and cold radiation and cold air fall to the lower part, so that the lower part of the intake grill 10 is affected. There was a problem that warps at both ends and the central part.

Further, due to the insufficient strength of the suction grill 10 itself, the opening and closing feeling is weak and the opening and closing feeling is not good.

In view of the above-mentioned conventional problems, it is an object of the present invention to further improve the strength and appearance while maintaining the heat insulating property of the suction grille 10.

Another object of the present invention is to provide an air conditioner capable of reducing the number of parts and cost.

[0009]

In order to solve the above problems, the present invention provides a plurality of ribs in the longitudinal direction on the back surface of the suction grill, and installs a heat insulating material by connecting the upper and lower ends of the ribs. Then, an air layer is provided to reduce the change due to heat and to make the strength stronger than before.

Further, by using a resin molding material having rigidity as the heat insulating material, the strength is further enhanced, the opening and closing sensation of the suction grill is improved, and the appearance when the suction grill is opened is improved.

[0011]

By the above means, the present invention prevents the intake grill from warping due to a low temperature of the heat exchanger during defrosting during heating operation and cold radiation and cold air falling to the lower part.

Further, according to the present invention, since the heat insulating material is a resin molded product, the heat insulating property is maintained, and the strength of the intake grill is increased to improve the open / close feeling, and the appearance when the intake grill is opened is improved. The number of parts can be reduced and cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2, reference numeral 1 denotes an underframe main body of an air conditioner, to which an intake grill 2 which constitutes a makeup grill with an oblique suction bar 2a and a front grill 3 which is attached so that the intake grill 2 can be opened and closed are attached. ing. A blower 4 and a heat exchanger 5 are arranged inside the front grill 3. An air filter 6 is arranged between the front grill 3 and the suction grill 2.

Further, a plurality of ribs 7 are provided on the back surface of the suction grill 2 in the longitudinal direction, and the heat insulating material 8 is arranged by connecting the upper ends of the ribs 7 to each other to provide an air layer 9. In the above configuration, the heat exchanger 5 becomes a low temperature during defrosting during heating operation, and the lower portion of the intake grill 2 is insulated by the heat insulating material 8 and the air layer 9 due to cold radiation and cold air falling to the lower portion. At the same time, the front grille 3, the air filter 6 and the heat insulating material 8 are sealed to prevent the cool air from falling, thereby preventing warpage.

Further, by using a resin material having rigidity as the heat insulating material, the strength is further improved, the opening and closing sensation of the intake grill is improved, the appearance when the intake grill is opened is improved, and the number of parts is reduced. The cost can be reduced.

[0016]

As is apparent from the above description, the present invention prevents the intake grill from warping due to low temperature of the heat exchanger during cold defrosting during heating operation and cold radiation and cold air falling to the bottom. To do.

Further, according to the present invention, since the heat insulating material is a resin molded product, the heat insulating property is maintained, the strength of the intake grill is increased and the appearance of the opened grill is improved, the number of parts is reduced and the cost is reduced. It has a great effect such as reduction.
