Definitions

  • the present invention relates to a wall-hanging air conditioner to be installed on a wall surface.
  • a refrigerant pipe extending from a heat exchanger incorporated in a unit is allowed to penetrate through a base body of the unit and extracted to the rear surface side. Further, the refrigerant pipe is disposed along the rear surface of the base body, and is allowed to penetrate through the wall surface at an appropriate position and extracted to the outside of the room so that the refrigerant pipe is connected to an exterior unit (for example, see Patent Literature 1).
  • Patent Literature 2 discloses a structure in which a notch through which a refrigerant pipe is allowed to penetrate is provided in an upper surface of a side portion of the base body, and the refrigerant pipe is extracted to the rear surface side from the inner surface side of the base body through the notch.
  • the notch through which the refrigerant pipe is allowed to penetrate is provided in the base body, there is a possibility that the strength of the base body to be assembled with a heat exchanger, an air blower, a front panel, or the like is lowered. Further, to allow the refrigerant pipe to penetrate through the notch, it is necessary to move the heat exchanger downward along the notch from an upper portion of the base body, which is not necessarily favorable in terms of assembly workability.
  • the present invention has been made in view of the above-mentioned circumstances, and therefore it is an object of the present invention to provide a wall-hanging air conditioner capable of improving assembling workability of a heat exchanger on a base body and securing a sufficient strength of the base body.
  • a wall-hanging air conditioner according to the present invention includes: a base body to be assembled with a heat exchanger, an air blower, and the like; and a refrigerant pipe extended from the heat exchanger assembled on an inner surface side of the base body, the refrigerant pipe being extracted to a rear surface side of the base body and disposed along the rear surface of the base body.
  • the base body is separable in a longitudinal direction at a portion penetrated through by the refrigerant pipe and divisible into right and left portions, and a divisible side pipe cover is detachably/attachably mounted on the base body.
  • the base body is separable in the longitudinal direction at the portion penetrated through by the refrigerant pipe and divisible into the right and left portions, and the divisible side pipe cover is detachably/attachably mounted on the base body. Accordingly, the divisible side pipe cover is dismounted and the heat exchanger is incorporated into the base body in a state where one side of the portion through which the refrigerant pipe is allowed to penetrate is opened, thereby enabling positioning and incorporation of the refrigerant pipe directly to the penetrated portion of the base body with no limitation on the direction in which the heat exchanger is incorporated.
  • the side pipe cover is mounted on the base body, thereby enabling assembly of the heat exchanger on the base body in a state where the refrigerant pipe extended from the heat exchanger is allowed to penetrate to the rear surface side of the base body. Consequently the assembling workability of the heat exchanger can be drastically improved without the need to allow the refrigerant pipe extended from the heat exchanger to penetrate through a through-hole or to move the refrigerant pipe downward along a notch.
  • a screwing portion and an engagement portion may be provided between at least two upper and lower portions between the base body and the side pipe cover, and the side pipe cover may be engaged with the base body by the engagement portion and may be screwed to be detachably/attachably mounted.
  • the screwing portion and the engagement portion are provided between at least two upper and lower portions between the base body and the side pipe cover, and after the side pipe cover is engaged with the base body by the engagement portion, the side pipe cover is screwed to be detachably/attachably mounted. Therefore, the side pipe cover divisible from the base body can be detachably/attachably mounted on the base body by the screwing portion and the engagement portion which are provided at least two upper and lower portions at the divided right and left positions. Accordingly, the coupling strength of the divided side pipe cover can be relatively easily secured.
  • the side pipe cover may be divided into right and left portions at a side position relative to a mounting portion on an installation plate at which the base body is installed on a wall surface.
  • the side pipe cover is divided into right and left portions at the side position relative to the mounting portion on the installation plate at which the base body is installed on the wall surface. Accordingly, the right and left divided positions of the base body do not overlap the mounting portion on the installation plate, thereby avoiding the situation in which the division of the base body has an adverse effect on the installation strength of the air conditioner. Consequently, the installation workability can be maintained and secured, regardless of the division of the base body.
  • the divisible side pipe cover is dismounted and the heat exchanger is incorporated into the base body in a state where one side of the portion through which the refrigerant pipe is allowed to penetrate is opened, thereby enabling positioning and incorporation of the refrigerant pipe directly to the penetrating portion of the base body with no limitation on the direction in which the heat exchanger is incorporated.
  • the side pipe cover is mounted on the base body, thereby enabling assembly of the heat exchanger on the base body in a state where the refrigerant pipe extended from the heat exchanger is allowed to penetrate to the rear surface side of the base body. Consequently the assembling workability of the heat exchanger can be drastically improved without the need to allow the refrigerant pipe extended from the heat exchanger to penetrate through a through-hole or to move the refrigerant pipe downward along a notch.

  • the control box 8 is incorporated into a right side portion of the base body 3, and controls the operation of the air conditioner 1 by using a command from a remote controller.
  • the front cover 10 covers the front surface, the upper and lower surfaces, and the right and left surfaces of the above-mentioned instruments incorporated into the base body 3.
  • a suction grill 16 for sucking the air within the room is formed on the upper surface and the front surface of the front cover 10.

  • the side pipe cover 17 is divided into right and left portions at a side position relative to the mounting portion 18 for mounting the base body 3 on the installation plate 2 installed on the wall surface, and has a notch 19 formed therein through which the refrigerant pipe 7 is allowed to penetrate.
  • the notch 19 is formed on the rear surface side of the base body 3 and extended downward from the penetrating position. As illustrated in Fig. 5 , the refrigerant pipe 7 is extended downward and is then disposed in one of the left direction (direction illustrated in the figure) and the right direction along the lower portion on the rear surface of the base body 3.
