Description

Discharge airflow control device for bathroom type air conditioner {DISCHARGE AIR FLOW CONTROL APPARATUS FOR BATHROOM TYPE AIR CONDITIONER}

The present invention relates to a discharge airflow control apparatus for a bathroom air conditioner, and more particularly, to a discharge airflow of a bathroom air conditioner, in which a user's convenience can be enhanced by appropriately adjusting the discharge airflow according to an operation mode. It relates to a control device.

In general, an air conditioner is an air conditioner that is disposed in a room, a living room or an office, or a space such as a business store to maintain a comfortable indoor environment by controlling air temperature, humidity, cleanliness, and airflow.

In general, air conditioners are referred to as air conditioners for cooling indoors in summer. Some of these air conditioners reverse the flow of refrigerant in a refrigeration cycle to selectively perform cooling and heating functions, so-called heat pumps. There is a combined air-conditioning and air conditioner called a pump or an air conditioner for four seasons.

On the other hand, according to the change of living environment, most of the living spaces are equipped with bathrooms and toilets (hereinafter referred to as bathrooms), and these bathrooms always have water and drains to drain used water. Various fungi, bacteria, etc. are not only easy to breed, but also cause various odors, causing discomfort. In particular, during the rainy season, or on a snowy day, the sun does not go well and the wind does not pass well, such as mold easily caught, odor is not easily removed.

A bathroom type air conditioner with cooling and heating functions has been proposed to solve the harmful effects of using the bathroom.

1 is a cross-sectional view showing an example of a conventional bathroom type air conditioner. As shown, the bathroom-type air conditioner includes an accommodation space, a first and second circulation paths 11 and 21 to circulate the air in the bathroom, and a discharge path to discharge the air inside to the outside. A casing 10 is formed and installed on the ceiling 5 of the bathroom, and a first blowing fan 18 and a first heat exchanger disposed in the first circulation passage 11 in the casing 10. 16, a second blowing fan 29 and a second heat exchanger 27 disposed in the second circulation passage 21, and a compressor 25 disposed at one side of the second heat exchanger 27 to compress the refrigerant. Equipped with.

A first suction opening 12 is formed at one side of the bottom of the casing 10, and air passing through the first heat exchanger 16 is sucked through the first suction opening 12 at one side of the first suction opening 12. The first discharge port 14 is formed to be discharged. The first suction port 12 is provided with a temperature detection sensor 13 and a humidity detection sensor 15 so as to detect the temperature and humidity of the bathroom.

The second suction port 22 is formed at one side of the first suction port 12, and the air sucked through the second suction port 22 at one side of the second suction port 22 and flowed along the second circulation path 21. The second discharge port 24 and the discharge port 33 is formed so that the air of the bathroom can be discharged to the outside of the bathroom so that the discharge to the interior of the bathroom.

The second discharge port 24 and the discharge port 33 are provided with a damper 32 to selectively open and close the second discharge port 24 and the discharge port 33, the discharge port 33 to the outside of the air in the bathroom The other end of the exhaust duct 35, one end of which is connected to the outside so as to be discharged, is connected to each other.

By this configuration, during cooling, the refrigerant compressed by the compressor 25 is radiated through the second heat exchanger 27, and absorbs the latent heat of the surroundings in the first heat exchanger 16 through an expansion device (not shown). Cooling will be performed. The first blower fan 18 sucks air through the first inlet 12 to blow air cooled by heat exchange in the first heat exchanger 16 to the inside of the bathroom, and the second blower fan 29 The heat dissipation of the refrigerant is promoted by the air sucked through the second suction port 22. At this time, the damper 32 blocks the second discharge port 24 and rotates so that the discharge port 33 is opened so that the air heat-exchanged with the second heat exchanger 27 is discharge port 33 and the exhaust duct 35. Is discharged to the outside through.

At the time of heating, the refrigerant compressed by the compressor 25 by the four-way valve (not shown) flows to the first heat exchanger 16 to radiate heat, and the latent heat of the surroundings in the second heat exchanger 27 through the expansion device (not shown). After absorbing this, it is sucked back into the compressor 25.

However, in such a conventional bathroom type air conditioner, cold air or hot air is discharged downward through the first discharge port 14 or the second discharge port 24 when cooling or heating, so that the cold or hot air directly contacts the body. If there is a problem that the user is offended.

Accordingly, it is an object of the present invention to provide a discharge airflow control apparatus for a bathroom type air conditioner, which can enhance user convenience by appropriately adjusting the airflow discharged according to an operation mode.
