Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an air conditioner in which a plurality of suction grill members are arranged on a main body.

(B) Prior art As an air conditioner in which a plurality of suction ventilation grills are formed and these suction ventilation grills are arranged side by side on the main body, there is one disclosed in Japanese Utility Model Publication No. 62-34175. .

(C) Problem to be Solved by the Invention In this air conditioner, since the ventilation opening is provided only in front of the suction ventilation grill, for example, when the heating operation of the air conditioner is stopped, a heat exchanger is provided in the air conditioner. Dissipated heat is likely to accumulate, and if each suction ventilation grill is unevenly heated by the accumulated heat, the deformation state of the suction ventilation grilles will be uneven, and the ventilation grilles will be continuous. There is a possibility that it may lose its appearance and may not look good.
Further, a makeup sash or the like is used around the ventilation grill to cover the attachment portion of the grill to improve the appearance of the attachment, so that the makeup sash or the like is required.

The present invention makes it difficult for heat to stay inside the air conditioner,
It is an object of the present invention to suppress deformation of a plurality of ventilation grills attached side by side due to heat, and to easily attach these ventilation grills.

(D) Means for Solving the Problem In order to achieve this object, the present invention is to provide openings on the front surface and the top surface of a plurality of suction grill members arranged in the main body. Further, this suction grill member is provided with a mounting piece which is attached to the main body and is covered with another suction grill member.

(E) Operation The heat trapped inside the machine is released from the opening provided on the top surface of the suction grille member to suppress the thermal deformation of each suction grille member to a small extent, and the attachment piece of the suction grille member is connected to another suction grille member. I cover it so that I can't see it.

(F) Embodiment FIG. 1 is an exploded perspective view of an air conditioner (indoor unit of a separation type air conditioner) 1 of the present invention. Reference numeral 2 denotes a sheet metal body (frame), which includes a top plate 3, a back plate 4, a left support plate 5, a right support plate 6, and a lower plate 7 extending to the lower right of the right support plate 6. , These plates are welded and integrated. A cross flow fan 8 is arranged so as to pass through the hole 9 of the left support plate 5 and the hole 10 of the right support plate 6. Reference numeral 11 denotes a bearing, into which the non-driving shaft 12 of the fan 8 is inserted and fixed to the left side surface of the left support plate 5. Reference numeral 13 is a motor for driving the fan 8, and a shaft 14 of the motor 13 is fixed to a boss 15 of the fan 8. The mounting piece 16 of the motor 13 is fixed to the right side surface 17 of the right support plate 6. Reference numeral 18 denotes an electrical equipment plate, and a flange piece 19 of this plate is fixed to the edges of the top plate 3 and the back plate 4 of the frame 2. An electrical component 21 is attached to the inner surface of the electrical component plate 18. Reference numeral 22 is a mounting member that constitutes a part of the main body, and is fixed across the lower front edge (not shown) of the left support plate 5 and the lower front edge 23 of the right support plate 6. The mounting member 22 is formed in a substantially J shape so that the rear portion 24 is higher than the front portion 25. This rear portion 24 acts as a tongue portion of the cross flow fan 8. A drain van 26 is placed on the mounting member 22. 27 is a heat exchanger,
Both left and right tube plates 28 are attached to the front sides 29 of the left and right support plates 5 and 6. 30 is a mounting member 22 and a back plate 4 of the frame 2
It is a blowing member connected to the
And vertical blades (not shown) are incorporated. Reference numeral 32 denotes an auxiliary top plate arranged in front of the top plate 3 of the frame 2, and a flange piece 33 bent downward is formed at the front portion thereof. Reference numeral 34 is a suction grill member having openings 35 on the front surface and the top surface, and four suction grill members are arranged side by side (two are omitted in FIG. 1) and arranged on the front surface of the heat exchanger 27. A blind member 36 is arranged to the left of the suction grill member 34 at the right end. This suction grill member 34
Also, the blind member 36 has its upper portion 37 on the front edge 38 of the auxiliary top plate 32,
The lower portions 39 are fixed to the vertical pieces 40 of the blowing member 30, respectively. An air filter 41 is arranged on the back side of the suction grille member 34. Reference numerals 42 and 43 denote left and right side panels, and these panels are provided on the frame 2 such as a blowing member 30, a suction grill member 34, and a blind member 39.
It is attached to the frame 2 in a state where the exterior body such as is attached.

FIG. 2 is a perspective view showing a mounting state of the suction grill member 34. Reference numeral 50 denotes a protrusion provided on the left side surface of the suction grill member 34, and 51 denotes an engaging hole provided on the right side surface of the suction grill member 34, with which the projections 50 of the adjacent right suction grill members 34 are fitted. Reference numeral 52 denotes a mounting piece that extends laterally from the rear edge of the right side surface of the suction grill member 34, and is fitted into the hole 53 of the vertical piece 40 of the blowing member 30. The mounting piece 52 is fixed to the front portion 25 of the mounting member 22 with a screw (not shown). The attachment piece 52 and the screw are configured so as not to project forward from the hole 53 of the blowout member 30, and at the left portion of the adjacent right-side suction grill member 34,
This mounting piece 52 is hidden.

In such an air conditioner 1, when the cross flow fan 8 is rotated, the room air is sucked into the inside of the machine from the front and upper openings 35 of the suction grille member 34, and the air filter.
After passing through 41, it is cooled or heated by the heat exchanger 27 and is discharged from the outlet 54 of the outlet member 30. By providing the upper surface opening 35 of the suction grille member 34, the heat inside the machine easily escapes from the opening 35 on the upper surface when the heating (heating) operation is stopped, for example, so that the heat is less likely to stay inside the machine. Since the plurality of suction grill members 34 arranged in this way and the deformation and expansion of the members due to heat are minimized,
The appearance of the suction grille members 34 can be improved by maintaining the continuity of the claws of the plurality of suction grille members 34.

(G) Effect of the Invention As described above, the present invention provides openings on the front surface and the upper surface of a plurality of suction grill members arranged on the main body. The opening serves as a suction passage, the suction resistance is suppressed to be small, and the opening on the upper surface serves as a passage for dissipating heat inside the machine when the air conditioner is stopped, so that it is possible to prevent heat from staying inside the machine. Further, by making it difficult for heat to be stored in the machine when the operation is stopped, it is possible to suppress thermal deformation of the respective suction grille members and improve the appearance of the air conditioner.

Also, since the attachment piece of the suction grille member is covered with another suction grille member, the appearance of the suction grille member in terms of mounting can be improved.
