Description

  The present invention relates to an air conditioner, and more particularly to connection of a hose that discharges indoor air or drain water to the outdoors.

An indoor unit of a conventional air conditioner with a ventilation function that guides indoor air to the outside and ventilates includes a ventilation unit including a heat exchanger, a blower fan, a ventilation fan, and the like, and the ventilation unit is a side portion of the indoor unit. It was attached to. The exhaust port of the ventilation fan is provided with an adapter and a circular elbow, to which a hose having a circular base connection and a substantially D-shaped tip is connected, so that the direction of the exhaust path can be changed. (For example, refer to Patent Document 1).
JP 2000-171054 A

  However, in the conventional configuration, if the ventilation fan is disposed on the side surface of the indoor unit, the ventilation duct mouth and the indoor unit main body outlet are close to each other, and the indoor unit main body outlet opening cannot be sufficiently secured, There were problems such as deformation of the hose and increased difficulty of construction work.

  An object of the present invention is to provide an air conditioner that solves the above-described conventional problems and improves the workability by facilitating the routing of indoor air or a drain water delivery hose.

  In order to solve the above-described conventional problems, an air conditioner according to the present invention includes an outdoor unit and an indoor unit connected to the outdoor unit via a refrigerant pipe, and discharges indoor air or drain water to the outside. The hose is connected to the indoor unit through a receptacle and an elbow, and the elbow has a substantially D-shaped cross section, which reduces the interference with other pipes and hoses and exits the indoor body. The opening area can be reduced.

  In the air conditioner of the present invention, piping construction of a hose for discharging indoor air or drain water from an indoor unit to the outside is extremely easy, and an improvement in aesthetics can be realized.

  The first invention comprises an outdoor unit and an indoor unit connected to the outdoor unit via a refrigerant pipe, and the hose for discharging indoor air or drain water to the outdoors is received by the indoor unit. In addition to being connected via an elbow, the elbow has a substantially D-shaped cross section, which can reduce interference with other pipes and hoses and reduce the opening area of the indoor body outlet.

  In the second invention, in particular, the elbow of the first invention is provided with a first flange having a screw hole and a groove at one end, and a second flange is provided at the other end. Since the mounting position is clear and erroneous connection can be prevented, the connection can be easily made.

  In the third aspect of the invention, the first and second ribs are provided on the holder of the first or second aspect of the invention, and the mounting position can be changed by changing the shape and position of the first and second ribs. Can be clarified, and incorrect connection can be prevented.

  In the fourth aspect of the invention, in particular, the first rib of the third aspect of the invention is brought into contact with the first flange, and the second rib is fitted to the groove portion, thereby positioning the receiving tool and the elbow in the circumferential direction. Therefore, both parts can be attached to the indoor unit without being displaced in the circumferential direction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
Hereinafter, the air conditioner in the 1st Embodiment of this invention is demonstrated using figures.

  In FIG. 1, the air conditioner of the present embodiment includes an outdoor unit (not shown) and an indoor unit 1 connected to the outdoor unit by a refrigerant pipe 4. Reference numeral 2 denotes a ventilation hose for sending indoor air to the outside, and a receptacle 6 having a discharge port 7 communicating with a ventilation fan (not shown) built in the indoor unit 1 and an elbow having a substantially D-shaped cross section. 5 is connected to the indoor unit 1. 3 is a drain hose for drainage.

  As shown in FIG. 2, the receptacle 6 is arranged in the vicinity of the side surface of the indoor unit 1 so that the discharge port 7 overlaps the main body outlet 1a. FIG. 7 shows the layout of these pipes in the cross section of the indoor unit. In the figure, the drain hose 3, the refrigerant pipe 4, and the elbow 5 are arranged so as to be in close contact with each other.

  The elbow 5 is provided with a first flange 5a having a screw hole 5e at one end and a groove 5c, and a second flange 5b at the other end to clarify the mounting position and prevent erroneous connection.

  The receiving member 6 is provided with a first rib 6a and a second rib 6b so that the mounting position is clear and can be easily connected without erroneous connection.

  When the elbow 5 is attached to the receptacle 6, the first flange 5 a of the elbow 5 abuts on the first rib 6 a of the receptacle 6, and the groove 5 c of the elbow 5 is fitted with the second rib 6 b of the receptacle 6. In combination, the positioning in the circumferential direction is possible.

  As described above, according to the present embodiment, the elbow 5 has a substantially D-shaped cross section, thereby reducing interference with other pipes and hoses and reducing the opening area of the main body outlet 1a. I can do it.

  Further, by providing the first flange 5a and the groove 5c at one end of the elbow 5 and providing the second flange 5b at the other end to make the shapes of both ends different, the mounting position becomes clear and erroneous connection can be prevented. So it can be connected easily.

  Moreover, by providing the receiving device 6 with the first and second ribs 6a and 6b having different shapes and / or forming positions, the mounting position of the receiving device 6 can be clarified and erroneous connection can be prevented. it can.

  Furthermore, since the first rib 6a is brought into contact with the first flange 5a and the second rib 6b is fitted to the groove 6c, the elbow 5 and the receiving member 6 are positioned in the circumferential direction. Both components can be securely attached to the indoor unit 1 without shifting in the circumferential direction.

In the above-described embodiment, the elbow 5 has been described for attaching the ventilation hose 2 that discharges indoor air to the outdoors. However, the elbow 5 may be used for attaching a hose that is used to drain water.

  As described above, the air conditioner according to the present invention can easily construct a hose pipe for discharging indoor air from an indoor unit to the outside, and can improve workability and aesthetics. The present invention is not limited to this, and can be applied to various devices such as a washing machine that requires connection of a hose and whose drawing direction can be arbitrarily changed.
