Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-mounted air conditioner, and more particularly to a structure for restricting the opening of a suction grill in a floor-mounted air conditioner.

[0002]

2. Description of the Related Art In general, a floor-mounted air conditioner is provided with a blower and a heat exchanger in a vertically long rectangular parallelepiped casing, and the indoor air sucked from a suction grill provided on a front surface of the casing. The conditioned air obtained by cooling or heating by the heat exchanger is blown into the room from a blow grill provided on the front surface of the casing (for example, see Japanese Utility Model Laid-Open No. 1-167544).

[0003] By the way, in a floor type air conditioner,
There are two types: a type in which a blower is arranged on the leeward side of the heat exchanger (ie, on the outlet grill side), and a type in which a blower is arranged on the leeward side (ie, on the suction grille side) of the heat exchanger. In addition, since the suction grill has a built-in filter for removing dust from the suction air, the filter needs to be replaced, and the suction grill needs to be openable and closable with respect to the casing.

However, when the suction grill is made freely openable and closable as described above, if the degree of opening is made free, when the suction grill is largely opened, a hand is erroneously inserted inward from the opening. If a rotating machine such as a blower is disposed inside, the hand may touch the rotating machine. In particular, in the case where the blower is provided on the windward side of the heat exchanger and in the lower part in the casing, the above-mentioned anxiety becomes more remarkable because the position of the suction grill is lowered.

When equipment such as a blower is provided inside the suction grill, it is necessary to open the suction grill fully when performing maintenance and inspection of these equipment.

Therefore, the present applicant regulates the opening of the suction grill between the suction grill and the casing so that the filter can be attached and detached and a finger cannot be inserted. It has been proposed that an opening degree regulating means capable of releasing the regulation be interposed (Japanese Patent Application No. Hei 8-
292896).

[0007]

However, in the case of the above-mentioned prior application, although the opening degree of the suction grille can be regulated by the opening degree regulating means, a separate holding means for maintaining the closed state of the suction grille is used. A magnet as a member is used. That is, the opening degree regulating means for regulating the opening degree of the suction grille and the magnet for holding the closed state of the suction grille are required, which leads to an increase in the number of parts, an increase in the cost of parts, and an increase in the number of assembling steps.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is possible to regulate the opening degree of a suction grill and maintain a closed state with a single member, thereby achieving both safety and cost reduction. It is intended for.

[0009]
