Description

[Detailed Description of the Invention] Industrial Application Field The present invention connects the air-conditioned space and the main body of the air conditioner through a duct, and provides an air outlet for cooling and heating. The present invention relates to a wind direction changing device for an air conditioner that performs heating and cooling air conditioning by using a damper to control the ventilation path of blown air.

Conventional configuration and its problems Air conditioner 1 performs air conditioning by connecting the air conditioned space and the air conditioner main body using a duct. The outlet and air inlet are installed for air conditioning such as heating and cooling.

In such a configuration, the temperature distribution within the air-conditioned space during heating is not good, which significantly impairs comfort.

Conventionally, as shown in Fig. 5, a plurality of air outlets are provided above and below the wall surface of the air-conditioned space, and a duct 101 that communicates the air conditioner and the air-conditioned space is branched vertically in the middle. Air outlets 102 provided above and below the air-conditioned space,
It is connected to 103.

Furthermore, a fluid blowing element 106 is provided in front of the ventilation path branching point of the duct 101, and by controlling this fluid blowing element 106, during cooling, cold air is blown from the air conditioner main body to the top and bottom of the air conditioned space. The air is directed toward the upper air outlet 102 of the air outlets 102 and 103, and during heating, the air is directed downward to the air outlet 103.

In addition, the intake air from the air-conditioned space to the main body of the air conditioner is always taken in through a separately provided suction port 104.

In such a configuration, when heating and cooling, the upper air outlet 102 is not used for heating, and conversely, the lower Suita Q103 is not needed for cooling. 1 fluid blowout element 1
06 and a dedicated inlet 104 are required.However, the structure of the duct 101 that communicates the air conditioner body with the air outlet and inlet provided in the air-conditioned space is complicated, and the installation and construction work requires a dedicated inlet. This one is more expensive because of the opening.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and provides a duct body for an air conditioner that is simple in structure and inexpensive.

Structure of the Invention First and foremost, the present invention provides a partition plate in the duct that divides the ventilation passage into two parts, upper and lower. The entrance of the air passage is divided into an air outlet and an air intake, and an air passage control section using a damper is provided near the air passage entrance. The damper is integrally formed with a damper in the upper ventilation passage and a damper in the lower ventilation passage for the purpose of mutually switching the upper and lower ventilation passages into the outlet side ventilation passage and the suction side ventilation passage.

With this configuration, when the air conditioning state is cooling, the damper in the upper ventilation passage opens the upper air outlet opening and closes the upper suction opening. At the same time, the damper in the lower ventilation passage opens the lower inlet opening and closes the lower outlet opening.

Therefore, the upper ventilation passage becomes a cold air outlet ventilation passage, and the lower ventilation passage serves as an intake ventilation passage. Conversely, during heating, by changing the position of this damper, the lower ventilation passage becomes an outlet air passage, and the upper ventilation passage becomes an intake air passage.
