Description

  The present invention relates to a ventilation unit that exhausts indoor air to the outdoors, and more particularly, to a ventilation unit including a fixture to which two or more types of ventilation hoses having different diameters can be attached.

  In a ventilation unit that exhausts indoor air to the outside, for example, an indoor unit of a separation-type air conditioner having a ventilation function, the main body includes a suction port and a blower outlet, and a heat exchanger, a blower, and the like are accommodated inside the main body. ing. An air filter is attached to the front surface of the heat exchanger so as to capture dust from indoor air sucked into the main body. By the way, not only does the user always perform indoor air conditioning, but depending on the situation, there are cases where it is desired to ventilate the room effectively and quickly without opening the window. In order to cope with this situation, a ventilation unit to which a blower for exhausting indoor air to the outdoors and a ventilation hose communicating with this blower are connected.

  In the air conditioner equipped with the ventilation unit as described above, an indoor air intake port is opened at the front part of the indoor unit body facing the ventilation fan, and an indoor air ventilation port is provided at the rear part. Further, the ventilation port and the outdoor are communicated with each other by a ventilation hose inserted in a hose through-hole provided in the wall surface, and exhausted to the outside by the operation of the ventilation fan (Patent Document 1 and Patent Document 2).

However, since the ventilation hose of the air conditioner of patent document 1 and patent document 2 uses the same diameter ventilation hose, as shown in FIG. 12, according to the internal diameter of the hose through-hole provided at the time of building a house, Alternatively, ventilation hoses with different diameters cannot be selected depending on the ventilation volume. In order to eliminate these disadvantages, conventionally, as shown in FIG. 13, two or more types of hoses 41L and 41S having different diameters are connected and used (FIG. 13 (a)), or a small diameter is used. For connection of the ventilation hose 41S, the joint 41L1 of the large-diameter ventilation hose 41L was cut along the line XX and connected using this (FIG. 13 (b)). Such a ventilation hose connection method involves work such as cutting, which is complicated.
