Definitions

  • the present invention relates to an outdoor unit, and more particularly, to a soundproof structure of the outdoor unit.
  • noise generated during operation needs to be reduced as much as possible because the noise leads to complaints from neighborhood residents.
  • local administrations or governments request manufacturers to take measures in some cases.
  • a maximum noise value is provided by standards or laws.
  • Patent Literature 1 there has been proposed a technology for suppressing noise generated by a compressor by covering the compressor with a soundproof cover. Further, in Patent Literature 2, there has been proposed a configuration in which a compressor is arranged in a soundproof box.
  • a soundproof member is used with respect to a compressor arranged in a machine chamber so as to reduce noise.
  • the soundproof member cannot be provided to a lower part of the compressor because dew condensation water is generated near the lower part of the compressor. Accordingly, sound generated from a refrigerant circuit component other than a compressor, such as sound generated from a refrigerant pipe, cannot be suppressed. Even in a case in which the compressor is covered with the soundproof cover as disclosed in Patent Literature 1, dew condensation water needs to be discharged. Therefore, it is difficult to prevent leakage of sound through water-discharge holes formed in a base metal plate or other members.
  • JPH0397127U discloses a design of outdoor unit of air conditioner including a blower chamber that houses a heat exchanger and a blower that cools the heat exchanger with a partition plate inside the outer box, and a compressor, and a machine room for accommodating the compressor and a control room for controlling the compressor, the air conditioner comprising a U-shaped rubber on a mating face of a panel defining the machine room; an outdoor unit of air conditioner is characterized in that a packing to which a cushion is bonded is provided, and the airtight device is sealed in response to a change in clearance of the mating surface.
  • Document JPH0397127U discloses an outdoor unit according to the preamble of claim 1.
  • Patent Literature 2 it is described that a plurality of opening portions such as cutout portions and piping holes, which are opened to a space in which the air-sending device is arranged, are formed in the soundproof box accommodating the compressor. The sound of the compressor having leaked through those openings leaks to an outside with an outside air from the space in which the air-sending device is arranged. Thus, it is difficult to prevent the leakage of sound to the outside.
  • the present invention has been made to solve the above-mentioned problem, and has an object to provide an outdoor unit, which is capable of cooling electric components, discharging dew condensation water generated in a machine chamber, and enhancing a soundproof effect.
  • an outdoor unit as disclosed in claim 1.
  • the electric component chamber is defined by the second partition plate, which is mounted perpendicular to the first partition plate configured to partition the casing.
  • the machine chamber which is sealed by the third partition plate mounted to the second partition plate at a right angle and accommodates the compressor, is defined.
  • the air passage for allowing flow of air is formed on the side of the third partition plate opposite to the machine chamber.
  • FIG. 1 is a perspective view of an outdoor unit 1 according to the embodiment.
  • an outer shell panel 6a on a front side, an outer shell panel 6b on a back side, outer shell panels 6c and 6d on lateral sides, an outer shell panel 6e on a top side, and a base metal plate 2 form outer portions of the outdoor unit 1.
  • the base metal plate 2 and the outer shell panels 6a to 6e surrounding the base metal plate 2 form a casing 1a of the outdoor unit 1.
  • the outdoor unit 1 accommodates a fan, a fan motor, an air-heat exchanger, and a compressor.
  • Air is caused to flow from the outer shell panel 6b on the back side to the outer shell panel 6a on the front side by drive of the fan, thereby performing heat exchange between the air and refrigerant in the air-heat exchanger.
  • the outdoor unit 1 which accommodates the air-heat exchanger and the compressor, and an indoor unit, which accommodates an indoor-side heat exchanger and an expander, are connected to each other by a refrigeration circuit, to thereby form a refrigeration cycle.
  • a four-way valve configured to switch a flow direction of the refrigerant and an accumulator configured to accumulate the refrigerant may be connected to the refrigeration circuit forming the refrigeration cycle as appropriate.
  • Fig. 2 is a back view of the outdoor unit 1 of Fig. 1 .
  • an opening for taking in air for performing heat exchange in the air-heat exchanger and a first airflow hole 10 having a rectangular shape are formed in the outer shell panel 6b on the back side.
  • the first airflow hole 10 is formed so as to take in air for cooling electric components accommodated in the outdoor unit 1.
  • Fig. 3 is a perspective view of the base metal plate 2 of Fig. 1 .
  • a plurality of recessed portions 12, a plurality of protruding portions 13, and a plurality of base water-discharge holes 22 are formed in the base metal plate 2 on a bottom side of the outdoor unit 1.
  • the base metal plate 2 is a region for receiving dew condensation water generated in the outdoor unit 1.
  • the plurality of recessed portions 12 and the plurality of protruding portions 13 form water-discharge passages 14.
  • the water-discharge passages 14 cause the dew condensation water received in the base metal plate 2 to gather, to reach the base water-discharge holes 22 communicating with the water-discharge passages 14, and to be discharged to the outside through the base water-discharge holes 22.
  • the water-discharge passages 14 may be formed by, for example, subjecting a metal plate to drawing. It is not always required that the water-discharge passages 14 have a constant width, and a shape thereof is not particularly limited. However, it is preferred that the water-discharge passages 14 be formed into, for example, a plurality of lines which extend toward the lateral sides and merge at the lateral sides.

Openings are formed in the outer shell panel 6a on the front side and the outer shell panel 6b on the back side, respectively. Through drive of the fan, the air is taken in through the opening formed in the outer shell panel 6b on the back side, and is caused to flow toward the outer shell panel 6a on the front side, while being in contact with the air-heat exchanger.
  • the electric component chamber 4 is a space defined by a surface of the first partition plate 7 to which the second partition plate 8 is mounted and an upper surface of the second partition plate 8 in a space of the casing 1a which is partitioned by the first partition plate 7 and the third partition plate 9.
