Abstract

<P>PROBLEM TO BE SOLVED: To provide a floor type air conditioner having an inlet grill with less bars to prevent a drop of suction efficiency even with a wider non-opening face. <P>SOLUTION: This floor type air conditioner has an air filter 12, a blower (10) and a heat exchanger arranged from the upstream to the downstream in an air passage connecting an upstream inlet grill 5 disposed on the lower front side of a main body 1 to a downstream outlet port 6 disposed on the upper side of the main body. The inlet grill 5 is formed substantially in a circular shape extending to the front side of the main body, and is provided with a non-opening part 5a on the upper side and a plurality of bars 5b on the lower side. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a structure of a suction port of an air conditioner.

  The conventional floor-mounted air conditioner is, for example, as shown in the cross-sectional view of the main part in FIG. 6, a filter 12, a blower 10, and a heat exchanger 7 are sequentially disposed, and a drain pan 11 that receives condensed water is provided below the heat exchanger 7.

  The filter 12 is disposed close to the suction grill 5 (see, for example, Patent Document 1).

However, if the suction grill 5 is provided close to the filter 12, there is a problem that air is difficult to flow uniformly over the entire filter 12, and the intake efficiency is lowered, and the opening area of the suction grill 5 is reduced. When narrowed, air does not pass through the shaded portion 12a of the filter, so that there is a problem that clogging with dust occurs and the service life is shortened.
JP-A-8-200725 (page 3-5, FIG. 1)

  In view of the above-described problems, an object of the present invention is to provide a floor-mounted air conditioner in which the suction efficiency is not lowered even if the closing grille area is increased by reducing the number of suction grill bars.

The present invention is an air conditioner in which a filter, a blower, and a heat exchanger are disposed in an air passage connecting a suction port provided in a lower front portion of a main body and a blower outlet provided in an upper portion.
A suction grill attached to the suction port is bulged to the front, and a space is formed between the suction grill and the filter.
The upper half of the suction grille is a closed part, and the lower half is an opening made of a plurality of bars.

  Further, the plurality of crosspieces are configured to be radially formed with different angles toward the front.

  According to the present invention, a floor-mounted air conditioner in which a filter, a blower, and a heat exchanger are sequentially disposed in an air passage that connects a suction port provided in the lower part of the front surface of the main body and a blower outlet provided in the upper part. In the machine, the suction grille attached to the suction port is formed to bulge forward in a circular arc shape, and the upper part is provided with a closing part and the lower part is provided with a plurality of crosspieces, thereby improving the intake efficiency. Can be done. In addition, since the area occupied by the crosspieces is reduced, it is easy to obtain features in appearance, and since the crosspieces are provided radially, indoor air can be sucked from a wider range, and the suction efficiency similar to the conventional one is obtained. Obtainable. In addition, since a space is formed between the filter and the suction grille, air sucked from between the crosses passes through the entire surface of the filter through the space. Removal efficiency can be obtained.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.

  FIG. 1 is an external view showing an air conditioner according to the present invention, FIG. 2 is a cross-sectional view of an essential part showing an embodiment of an air conditioner according to the present invention, and FIG. 3 is an enlarged view of the essential part of FIG.

  Hereinafter, an air conditioner according to the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the inside of the main body 1 is partitioned up and down by a partition plate 2 provided with a ventilation hole 2a, and a blower chamber 3 is provided in the lower part and a heat exchange chamber 4 is provided in the upper part.

  A suction port is provided in the lower front part of the blower chamber 3, and a suction grille 5 bulging forward in an arc shape is attached to the suction port, and a blower outlet is provided in the upper part of the heat exchange chamber 4. 6 is provided. A filter 12 and a blower 10 are sequentially provided in an air passage that connects the suction port to which the suction grill 5 is attached and the outlet 6.

  The blower 10 accommodates a fan motor 8, a centrifugal fan 9 driven by the fan motor 10, and the centrifugal fan 9. The blower 10 has a suction hole in the rotation axis direction and a blowout hole corresponding to the ventilation hole 2a in the centrifugal direction. It is comprised with the provided fan casing.

  A heat exchanger 7 is disposed in the heat exchange chamber 4 of the air passage, and a drain pan 11 for receiving condensed water is provided below the heat exchanger 7 and in front of the partition plate 2.

  The suction grill 5 bulges forward in front of the main body 1 and is formed in an arc shape, and has a closed portion 5a at the top and openings by a plurality of bars 5b at the bottom, with the apex as a boundary.

  As shown in FIG. 3, the plurality of bars 5b are formed radially from the center of the arc toward the outer circumference of the arc.

  The filter 12 is vertically raised from the vicinity of the lower end of the crosspiece 5b, and a space 20 is formed between the filter 12 and the suction grille 5, as shown in FIG.

  Next, the operation of the above configuration will be described.

  Due to the operation of the blower, the indoor air sucked in from the front side of the crosspiece 5b of the suction grill 5 is made uniform by the space 20 acting as a buffer, so that the pressure and flow velocity are increased. A uniform flow passes through the entire filter 12. The air from which dust has been removed by passing through the filter 12 is heated or cooled by passing through the heat exchanger 7 through the blower and exchanging heat with the refrigerant flowing through the heat exchanger 7. It is like that.

It is an external view which shows the air conditioner by this invention. It is sectional drawing of the air conditioner by this invention. It is a principal part enlarged view of the air conditioner by this invention. It is principal part sectional drawing which shows the conventional air conditioner. It is principal part sectional drawing which shows the other Example of the conventional air conditioner.
