Description

TECHNICAL FIELD [0001] The present invention relates to an air vent opening and closing device for an air conditioner,

The present invention relates to a ventilation opening / closing device for an outdoor air conditioner room for an air conditioner. More particularly, the ventilation opening of an outdoor air conditioner room for an air conditioner is automatically opened and closed to enable smooth ventilation when an air conditioner is used. Thereby preventing the entry of muffler dust and noise into the outside environment, and when the air conditioner is used, the opening ratio of the ventilation opening can be adjusted to less than 100%, thereby preventing the rainwater from penetrating into the outdoor room To an air conditioner opening / closing device for an outdoor air conditioner for an air conditioner.

Generally, an air conditioner has been used to maintain the air conditioner. However, for the development of the technology and convenience of the use, the air conditioner is currently used to maintain the optimum temperature and humidity according to all the climatic conditions and the indoor environment.

Therefore, the above-mentioned air conditioner performs the cooling action by utilizing the phenomenon of absorbing the surrounding heat when the liquid evaporates. In addition to this cooling action, the air conditioner performs the dehumidifying action together.

In particular, room air conditioners, which are mainly installed in a small space such as a general home or a restaurant, are divided into an outdoor unit and an indoor unit. The outdoor unit corresponds to a compressor for compressing a refrigerant and a condenser for condensing the refrigerant. The outdoor unit includes noise generated by the compressor itself, noise generated by a cooling fan for effectively discharging heat emitted from the condenser, So it is installed on the roof of the building or outside the veranda. The indoor unit evaporates the refrigerant sent from the condenser and supplies it to the room.

However, in recent years, when the outdoor unit is installed outdoors, the service life of the product is shortened due to the occurrence of an accident such as a stolen path and a fear of theft, or a rapid aging phenomenon when the outdoor unit is exposed to the outside air For this reason, it is recommended to install an outdoor unit indoors.

Accordingly, when an outdoor unit room is designed and provided for storing and installing an outdoor unit at the time of building construction, when the ventilation hole of the outdoor unit room is maintained as it is, the thief can enter the house The problem was that most of them had fixed grilles or blades to prevent the delivery of thieves.

However, since the grill or the blade installed in the conventional ventilation hole is fixed and always kept in the open state, even if the thief can not enter, the grill or the blade is directly exposed to the outside air, It is not discharged naturally and is disturbed by the grill or the blades, so that it is piled up in the outdoor room and contaminates the outdoor room.

Therefore, if the foreign matter and dust that have flowed into the outdoor unit room are accumulated for a long time as described above, the outdoor unit is also polluted and dust accumulates in the outdoor unit.

As a result, when the outdoor unit is operated and overheated or a spark occurs, the fine dusts that pollute the outdoor unit cause the ignition to cause a fire, thereby causing the fire to spread to the room, , And these accidents are constantly occurring, but there are no measures to solve them.

In addition, since the grill and the blade partly block the ventilation hole, smooth ventilation is not achieved, thereby lowering the cooling efficiency.
