Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a hanging type outdoor unit of an air conditioner with an improved arrangement of piping connection ports.

<Prior Art> Conventionally, it is general that an outdoor unit of an air conditioner is provided with a pipe connection port on a rear surface or a side surface of a rectangular parallelepiped casing, and a liquid closing valve and a gas closing valve are attached to the piping connection port. (For example, Japanese Utility Model Laid-Open No. 62-52823).

<Problems to be solved by the invention> By the way, the hanging outdoor unit is hung and installed on the ceiling surface of a balcony or the like of a house, and piping work is usually performed from the lower surface of the unit after installation of the outdoor unit.

However, the pipe connection port of the conventional outdoor unit is provided on the rear surface or side surface of the casing, and in the case of a house with a narrow balcony, there is not enough room for installation, so a spanner should be inserted from below the outdoor unit to tighten it. Work is often difficult.

Therefore, an object of the present invention is to provide a hanging type outdoor unit capable of easily performing piping work even when the installation space is limited.

<Means for Solving the Problems> In order to achieve the above object, in the hanging type outdoor unit of the air conditioner according to the first aspect of the present invention, a diagonally cutout side is formed in a corner portion of a rectangular bottom surface of a casing. It is characterized in that a cutout surface extending upward from the cutout side is formed, a cutout space having an open lower end is formed in a corner portion of the casing, and a pipe connection port is arranged in the cutout surface.

The hanging type outdoor unit for an air conditioner according to a second aspect of the present invention is the hanging type outdoor unit for an air conditioner according to claim 1, wherein water drops are guided to the casing side at the lower edge of the cutout surface. The feature is that the drip-proof cover is detachably attached.

<Operation> Even when the space between the hanging type outdoor unit and the wall surface of the building is narrow, a notched space with an open lower end, that is, a space with an open lower end having a substantially triangular prism shape is formed in the notched portion of the casing. Further, since the pipe connection port is arranged in this cutout space, the pipe connection port does not significantly protrude from the external dimension surface of the rectangular parallelepiped of the casing, and therefore the working space can be easily secured. Moreover, since the lower end of the cutout space is open, piping work from below the hanging type outdoor unit is easy.

Further, when the drip-proof cover is detachably provided at the lower edge of the cutout surface, water droplets generated at the pipe connection port and the like are guided to the casing side and do not drip.

Also, since the drip-proof cover is removable, remove the drip-proof cover when performing piping work from below.
The piping work from below can be facilitated.

<Embodiment> The present invention will be described in detail below with reference to an embodiment shown in the drawings.

In FIGS. 1 and 2, 1 is a casing of a hanging type outdoor unit, 2 is a bottom surface of the casing, the casing 1 has a rectangular parallelepiped shape as a whole, and the bottom surface 2 has a substantially rectangular shape. Reference numeral 3 denotes a notched side formed by obliquely notching one of the corner portions of the bottom surface 2, 4 denotes a notched surface formed so as to extend above the notched side 3, and the notched surface 4 extends from the notched side 3 to the casing 1 Is formed up to the middle portion of the ridge line portion where the side surface 1a and the rear surface 1b intersect. Reference numeral 5 denotes a pipe connection port provided with a liquid shutoff valve 5a, 6 denotes a pipe connection port provided with a gas shutoff valve 6a, and these pipe connection ports 5 and 6 are arranged in the cutout surface 4, and in this embodiment, the casing 1 It is provided so that it does not project from the side surface 1a and slightly projects from the rear surface 1b.

3 and 4 show a state where the outdoor unit is installed in the building 8 by using the hanging metal fitting 7, and the space A between the wall surface 8a of the building 8 and the rear surface 1b of the casing 1 is shown.
Even if the pipe connection ports 5 and 6 are not sufficiently secured, the pipe connection ports 5 and 6 are provided on the cutout surface 4 and only slightly project from the rear surface 1b. The space between the two becomes large, and a space for connecting a refrigerant pipe (not shown) to the pipe connection ports 5 and 6 is secured. Therefore, guide the refrigerant pipe to the pipe connection ports 5 and 6,
Further, it is possible to easily perform the piping work of putting a hand under the unit and tightening it with a tool such as a spanner. Since the lower end of the notch space where the pipe connection ports 5 and 6 exist is open, the pipe connection work from below can be performed easily.

Further, since the pipe connection ports 5 and 6 may have a low pressure and cause dew condensation, as shown in FIG. 5, a drip-proof cover 9 that guides water droplets to the drain passage 10 is detachably attached with screws. There is. Since the drip-proof cover 9 is attached to the lower edge of the notch surface 4, that is, the portion of the notch side 3, the attachment work of the drip-proof cover 9 can be performed more easily than before. Since the drip-proof cover 9 can be removed,
Does not hinder the pipe connection work from below. Note that 11 is a drain joint.

<Effects of the Invention> As is apparent from the above description, the hanging type outdoor unit of the air conditioner of the present invention is provided with diagonally notched sides at the corner portion of the rectangular bottom surface of the casing.
A notched surface extending upward from the notched side is formed, a notched space having an open lower end is formed at a corner portion of the casing, and a pipe connection port is arranged on the notched surface.

Therefore, according to this invention, it is possible to reduce the amount of protrusion of the pipe connection port from the outer dimension surface of the casing or to prevent the pipe connection port from protruding at all, and the lower end is provided at the corner portion where the pipe connection port is provided. Since an open space with a nearly triangular prism shape, that is, a cutout space is created, piping work is easy even when there is no room in the installation space and the space between the outdoor unit and the wall of the building is narrow, and the lower end of the cutout space is open. Therefore, workability from below the hanging type outdoor unit can be improved.

Also, if a drip-proof cover is detachably attached to the lower edge of the cutout surface, it is possible to prevent water droplets from falling and to easily attach the drip-proof cover. Does not interfere with work.
