BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation unit of a separate type air conditioner, and more particularly, to a ventilation unit of a separate type air conditioner capable of compacting a product by improving an arrangement structure of parts and miniaturizing a product.

In general, an air conditioner uses a refrigeration cycle of a refrigerant consisting of a compressor, a condenser, an expansion device, and an evaporator to create a more comfortable indoor environment for a user. type) and one type (window type).

The separate type and the integrated type are functionally the same, but the separate type is a cooling / heating device installed in the indoor side and a heat dissipation / cooling and compression device installed in the outdoor side to connect the two separated devices with refrigerant piping. It integrates the function of cooling heat dissipation and installs it by drilling a hole in the wall of the house or hanging the device on the window.

Recently, an air conditioner that adds an air cleaning function for removing dust and foreign matter from indoor air or an oxygen generating function for generating indoor fresh air by generating oxygen is used.

6 is a perspective view showing a separate air conditioner according to the prior art.

As shown in FIG. 6, the separate type air conditioner according to the related art is disposed on the indoor side and heat exchanges with the indoor air to cool and heat the indoor room 10, and is arranged on the outdoor side and heat from the indoor unit 10. Receives the outdoor unit 20 for heat exchange with the outdoor air, and the refrigerant pipe (30) for connecting the indoor unit 10 and the outdoor unit 20 to transfer the refrigerant.

That is, the separate type air conditioner configured as described above cools or heats indoor air while the refrigerant circulates inside the indoor unit 10 and the outdoor unit 20 through the refrigerant pipe 30.

Even when the indoor unit 10 is equipped with an air purifying function and an oxygen generating function, if cooling or heating is performed for a long time in an enclosed indoor space, the indoor air may become cloudy and may adversely affect the user's health. Ventilation of the room is necessary.

However, the detachable air conditioner according to the prior art is not equipped with a function for ventilation to allow the user to open the window or door of the room directly to naturally ventilate the room, or to use a separate ventilation unit installed on the window or the wall. Forced ventilation of the room quickly.

As described above, it is very inconvenient for the user to open a plurality of windows or doors for indoor ventilation as well as a long ventilation time, and in particular, the recent building is a trend that the windows can not be opened and closed through the ventilation unit. Since only ventilation is possible, there is a problem in that a ventilation unit must be purchased and installed separately from the air conditioner.

Therefore, in order to solve the above problems, the ventilation unit may be installed in the indoor unit of the air conditioner, but the air conditioning and the ventilation may be performed together with the air conditioner, but the indoor unit may secure a space for the ventilation unit to be installed. Since the volume of the indoor unit is to be increased, there is a problem in that the installation space is limited.

The present invention has been made to solve the above problems, and an object of the present invention is to install a ventilation unit in an indoor unit of an air conditioner to ventilate a room, and a separate air conditioner in which the ventilation unit can be compactly configured.
