Problems solved by technology

[0003] When the size of the mesh of the net part is relatively small, although the fingers of the staff and the like can be reliably prevented from contacting the fan, the ventilation resistance is relatively large, and the ventilation noise is relatively large accordingly.
On the other hand, when the size of the mesh is relatively large, although the ventilation resistance is relatively small, there is a risk that the fingers of workers and others may come into contact with the fan.

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0029] Fig. 1 is a sectional view of an indoor unit; Fig. 2 is a perspective view showing a form observed when a part of the casing is viewed from the lower side of the casing; image 3 is the plan view of the protective cover; Figure 4 is a transverse sectional view of the annular component; Figure 5 It is a transverse cross-sectional view of a radial part.

[0030] As shown in FIG. 1 , an indoor unit (the indoor unit corresponds to an air conditioner) 1 according to the present embodiment is a ceiling-embedded indoor unit arranged in a ceiling in a room so as to be embedded in the upper surface of the ceiling. The indoor unit 1 includes a substantially rectangular parallelepiped casing 10 installed so as to be embedded in the upper side of the ceiling F, and a substantially square decorative panel 30 attached to the bottom surface of the casing 10 .

Abstract

The invention discloses a protective cover and an air-conditioner comprising the same. The protective cover (50) comprises a plurality of annular members (52) disposed coaxially with each other. A plurality of radial members (53) extending in the radial direction are so installed as to span the adjacent annular members (52, 52). The intervals between the adjacent annular members (52, 52) are larger than those between the adjacent radial members (53, 53) positioned between these annular members (52, 52).

Description

technical field [0001] The invention relates to a protective cover and an air conditioner including it. Background technique [0002] Conventionally, a protective cover for covering an air intake port provided in a casing of a ceiling-embedded air conditioner is known. The protective cover is used to prevent the fingers of the staff who maintain the air conditioner from contacting the fan in the housing. The protective cover of Patent Document 1 has a grid-shaped net portion. Patent Document 1: Japanese Laid-Open Patent Publication No. 2000-111087 [0003] When the size of the mesh of the mesh part is relatively small, although the fingers of workers and the like can be reliably prevented from coming into contact with the fan, the ventilation resistance is relatively large, and the ventilation noise is relatively large accordingly. On the other hand, when the size of the mesh is relatively large, although the ventilation resistance is relatively small, there is a possibi...
