Description

  The present invention relates to an air conditioner, and particularly to the shape of a suction grill.

As shown in FIG. 1, the indoor unit 1 of the air conditioner includes a filter 8, a heat exchanger 4, a blower fan 3, and an electrical component box (not shown) inside, and a base 20 that supports them, It is composed of a front panel 2 that is attached and a suction grille 5 that is attached to the front surface of the front panel 2. The suction air sucked from the upper suction port 9 and the front suction port 10 is exchanged into cold or warm air, and the air blowing The fan 3 sends the air from the blowout port 11 into the room.
In recent years, indoor units have been designed so that the surface of the suction grille has a flat surface shape without any crosspieces and melts into the interior of the room, and the method of sucking air from the top has become the mainstream. However, since the amount of suction from the front surface is insufficient due to the absence of the crosspiece alone, it is necessary to take in air from the front surface, and a horizontally long suction grille 5 in the center of the flat surface-shaped suction grille 5 as in the air conditioner A of FIG. An air conditioner has been proposed in which a concave portion 5a is provided and a part of the concave portion 5a is configured as a suction port 10 to increase the amount of suction air and to give an accentuating effect to a monotonous design with a flat surface. (Patent Document 1)
On the other hand, the suction grill is required to be detachable and easy to handle for inspection and repair of the air conditioner, cleaning of the filter and the suction grill, but the center of the flat grill shaped suction grill formed of synthetic resin is required. When a horizontally long concave portion is provided on one side and a part thereof is configured as the suction port 10, deformation and cracks are likely to occur from the suction port hole to the left and right side surfaces due to an impact such as dropping. Therefore, the air conditioner A is designed to reinforce the strength by providing flat surfaces at the front left and right ends without extending the suction grill recess 5a to the left and right ends.

In addition, there is a design in which a horizontally elongated recess extending to the left and right ends is provided at the center of a flat suction grill as in the air conditioner B of FIG. This gives a sharp and refreshing impression due to the visual effect of dividing the suction grill up and down, and the design can be differentiated, but the side becomes even weaker when extended to the left and right ends. In order to reinforce this, the air conditioner B has a wide flange width 5 g on the side surface of the suction grille. However, it is not easy for an operator such as a filter cleaner to hold a large suction grill having a lateral width of, for example, about 800 mm by spreading both arms to the left and right, especially when the width of the flange 5g on the side of the suction grill is wide. It does not fit inside, increases in size and weight, and may fall from the hand. (Patent Document 2)
In addition, a flat surface shape tends to result in poor design changes. Therefore, in order to characterize the design, for example, the brand name or catchphrase may be printed on the suction grill itself, but if the printing fails, one suction grill will be lost, It led to an increase in cost.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner that can suppress deformation and breakage even if the suction grille has a flat surface shape and is provided with a recess for a horizontally long suction port extending to the left and right ends at the center.

    In order to solve the above-mentioned problem, in an air conditioner provided with a suction grille that is disposed on the front side of an indoor unit and extends to the left and right side surfaces and a part of the same recess as a suction port, By providing the reinforcing portion, deformation and breakage can be suppressed.

  Moreover, although the said reinforcement part is formed shallower than another recessed part, even if it provides the said reinforcement part, it does not affect the design which a recessed part extends to the left-right side surface on the surface.

  Further, the strength can be further reinforced by fixing the reinforcing member to the front surface of the reinforcing portion. Furthermore, the design of the air conditioner can be changed by printing on the surface of the reinforcing member, and the range of variations is widened.

  Thus, even if the suction grill is provided with a reinforcing portion at the left and right ends of the recess, the suction grill has a flat surface shape and is provided with a recess for the horizontally long suction port extending to the left and right ends at the center. Damage can be suppressed. In addition to that, by reinforcing a reinforcing member on the front surface of the reinforcing part, it is possible to change the design of the air conditioner by printing on the surface of the reinforcing member as well as to reinforce the strength. spread.

    Hereinafter, an embodiment of the present invention will be described in detail as Example 1 based on the accompanying drawings. FIG. 1 is a sectional view showing the structure of an air conditioner to which a suction grill of the present invention is attached, FIG. 2 is a perspective view of the air conditioner to which the suction grill of the present invention is attached, and FIG. FIG. 4 is an explanatory view of the suction grill of the present invention. FIG. 4A is a front view, FIG. 4B is a side view, FIG. 4C is a partial enlarged view of AA 'cross section, and FIG. B 'cross-sectional partial enlarged view, (E) is a C-C' cross-sectional partial enlarged view, (F) is a D-part enlarged perspective view seen from the Y direction, and (G) corresponds to the A-A 'cross section in the second embodiment. FIG.

  As shown in FIGS. 1 and 2, an indoor unit 1 of an air conditioner according to the present invention includes a filter 8, a heat exchanger 4, a blower fan 3, and an electrical component box (not shown) inside, and a base for supporting them. 20, a front panel 2 attached to the base 20, and a suction grill 5 attached to the front surface of the front panel 2. The suction air sucked from the upper suction port 9 and the front suction port 10 is subjected to heat exchange. Cool air or warm air is sent out from the air outlet 11 into the room by the blower fan 3.

  The surface of the suction grill 5 has a flat surface shape, and a suction grill recess 5a that divides the flat surface in the vertical direction is provided substantially at the center of the suction grill 5. The concave portion 5a falls into a trapezoidal shape with the front side wide when viewed from the side, and the front suction port 10 is provided on the lower surface to take in air. The width of the front suction port 10 in the front view is substantially the same as that of the heat exchanger 4 provided therein.

  Further, as shown in FIG. 3, the suction grill 5 is detachable for inspection and repair of the air conditioner and cleaning of the filter 8 and the suction grill 5 included therein, and a locking shaft 12 at the upper end of the suction grill 5. Is pivotally supported by a fulcrum 13 at the upper end of the front panel 2. When the operator removes the suction grille 5 in the closed state to a position shown in FIG. 3 by a spring mechanism or the like, grasps the left and right ends of the suction grille 5 and lifts them upward, and lifts the locking shaft 12 from the fulcrum 13. remove. On the contrary, when the suction grill 5 is attached, the left and right ends of the suction grill 5 are gripped, the locking shaft 12 is aligned with the fulcrum 13, the suction grill 5 is lowered from the top, and the spring mechanism of the front panel 2 is placed. And so on.

  At that time, since the suction grill 5 has a width of about 800 mm, it is not easy for an operator to perform a series of operations with both arms extended to the left and right. Therefore, the thickness of the suction grill 5 is preferably a thickness that can be easily held in the hand, and the width 5g of the flange on the side surface of the suction grill 5 is 10 mm or less. However, since the concave portion 5a that divides the flat surface up and down is provided in the center of the thin suction grille with a flat surface shape processed with synthetic resin, the concave portion 5a becomes thin, so that deformation or breakage occurs during work. Is likely to occur.

  In order to solve this problem, the present invention provides reinforcing portions 5b at the left and right ends of the suction grill recess 5a. The reinforcing portion 5b is shallower than the other concave portions 5a as shown in FIGS. 4D and 4E, and the width of the reinforcing portion 5b is within the suction grill concave portion 5a as shown in FIG. 4F. It corresponds to a portion other than the front suction port 10. The rising portion 5c of the reinforcing portion 5b is inclined as shown in FIG. 4E to relax the box-like image. Further, as the second embodiment, as shown in FIG. 4 (G), the rising portion 5c has a gentle slope, so that it can have a sense of unity with the suction grill recess 5a. As a result, the side surface of the suction grill 5 is reinforced, and sufficient strength can be secured to prevent deformation and breakage.

  FIG. 5 is a perspective view of an air conditioner equipped with a suction grill showing Embodiments 3 and 4 of the present invention, and FIG. 6A is a partially enlarged view corresponding to the section CC ′ of FIG. 4B is a partially enlarged view corresponding to the CC ′ section of FIG. 4 in the fourth embodiment, and FIG. 4C is a partially enlarged view corresponding to the CC ′ section of FIG.

  In many cases, an electrical component box (not shown) is arranged inside the air conditioner near the portion D in FIG. In this case, since the width of the front suction port 10 is reduced by the width of the electrical component box, the width of the reinforcing portion 5b is adjusted to the width of the electrical component box as shown in FIG. The strength can be further reinforced by fixing the reinforcing member 6. Furthermore, the design of the air conditioner C, which is flat and poor in change, can be changed by printing a brand name, a catchphrase, etc. on the reinforcing member 6, and the range of variations is widened. Further, by printing on the conventional direct suction grille, it is possible to eliminate the loss of one suction grille due to defective printing.

  At that time, as a configuration for fixing the reinforcing member 6, silk printing was performed on the surface of the synthetic resin molded product as Example 3 as shown in FIG. 6A, and two locking claws 6 a were provided on the back surface. The reinforcing member 6 is locked by the locking claw 6a in a locking hole 5d provided on the surface of the reinforcing portion 5b.

  Alternatively, as Example 4, the reinforcing member 6 that is subjected to silk printing on the surface of the synthetic resin molding as shown in FIG. 6B or offset printing on the surface of the processed sheet metal product is used as a double-sided tape or the like. The adhesive 7 is adhered to the surface of the reinforcing portion 5b.

  In that case, as shown in FIG. 6C, as Example 5, a depression is provided on the surface of the reinforcing part 5b, and the reinforcing member 6 is shaped to follow the shape of the depression of the reinforcing part 5b. The adhesive 7 may be adhered to the dent of the reinforcing portion 5b.
