JP5558378B2 - Air conditioner outdoor unit - Google Patents

Description

  The present invention relates to an outdoor unit of an air conditioner, and more specifically, in an outdoor unit having a bell mouth on a front panel, so as to prevent snow melt and rain water from entering into the bell mouth to generate ice pillars. This relates to an outdoor unit of an air conditioner.

  As shown in FIGS. 9 and 10, the conventional outdoor unit of an air conditioner is made of a metal plate and is installed on the front surface of the outdoor unit body 1 for the purpose of preventing contact with the fan 12 by a human hand. A fan guard 11 is provided at an air outlet 5 provided in the recess 3 of the panel 2.

  If there is a gap g between the fan guard 11 and the front panel 2, when snow is accumulated on the top panel 9 of the outdoor unit main body 1 in a snowy area, the snow 30 is melted and the melted snow melt 31 becomes the front panel. 2 flows down on the surface of 2, enters through the gap g between the front panel 2 and the fan guard 11, is transmitted to the bell mouth 10, is cooled by the blowing air below the freezing point due to the operation of the air conditioner, and freezes on the bell mouth 10. However, the icicle 32 may interfere with the fan 12.

  In order to solve such problems, a guide groove is provided in the outer periphery of the air outlet of the front plate of the outdoor unit, and this guide groove allows snow melt and rain water droplets from the upper surface of the outdoor unit main body to flow into the air. Some are configured to guide downward along the outer periphery of the air outlet. In this guide groove, drainage holes communicating with the inside of the outdoor unit main body are provided in the horizontal direction in the upper and lower grooves and the left and right grooves, respectively, and snow melting water and rainwater are transmitted from the upper surface of the outdoor unit to the front plate of the outdoor unit main body. In this case, a technique is disclosed in which these water droplets flow down while being guided by a guide groove and are discharged from the drain hole into the interior of the outdoor unit body (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 62-29863 (page 2-3, FIG. 1)

  Since the outdoor unit described in Patent Document 1 is provided with drain holes at the upper and lower ends and the left and right ends of the guide groove portion, there are many water droplets flowing down the guide groove portion, and when the flow velocity of the water droplets flowing down increases, The water flowing down along the outer periphery of the air outlet through the guide groove cannot be regulated by the guide groove and flows into the bell mouth from the surface of the guide groove through the front plate. It was cooled by the blown air below the freezing point and freezed on the bell mouth, becoming an icicle and interfering with the fan, and there was a possibility that abnormal noise was generated or the fan was damaged.

  In addition, a drainage hole is provided in the guide groove, and when the drainage hole is touched by human eyes, there is a problem that the design of the outdoor unit is deteriorated and the appearance of the house where the outdoor unit is installed is deteriorated.

  The present invention has been made to solve the above-described problem, and prevents ice pillars from being generated on the bell mouth without melting snow or rain water into the bell mouth. In addition, it is intended to provide an outdoor unit of an air conditioner that does not impair the design by configuring the drain hole provided in the front panel so that it is not directly in contact with eyes. It is.

The outdoor unit of the air conditioner according to the present invention has a fan guard attached to the front side of the air outlet provided on the front panel, a bell mouth attached to the back side, and a fan installed on the back side of the bell mouth. An outdoor unit body
Above the air outlets in the front side of the front panel is provided with a trough-shaped guide roof a circle arc, the guide roof, a rear wall, has a groove formed by the bottom and the front wall, the groove portion Both end portions are closed by end walls, and a water flow hole communicating with an opening provided in the front panel is provided in the rear wall .

  According to the present invention, rain water flowing down along the front surface of the front panel does not enter the bell mouth, and it is possible to prevent an ice column from being generated on the bell mouth, and drainage provided on the front panel. Since the mouth is not directly in contact with the eyes, an outdoor unit of an air conditioner that does not impair the design can be obtained.
