Detailed ways

As shown in FIGS. 1-8 , the present disclosure provides an air conditioner indoor unit, which includes an air duct 1 , an air outlet 2 and an air guide mechanism 3 , and the air outlet 2 includes a first air outlet end 21 and a second air outlet end 22 , Air flows in the air duct 1 and flows from the first air port end 21 to the second air port end 22 , and the air guide mechanism 3 can move into the air outlet 2 and is located at the first air port end 21 and the second air port end 22, so that part of the air flow in the air duct 1 that flows to the second air port end 22 can be led out through the air guide mechanism 3 (that is, toward the air conditioner indoor unit). The front side is the side facing the user, and the rear side is the side close to the wall where the air conditioner is installed).

In the air conditioner indoor unit provided by the present disclosure, by arranging an air guide mechanism at the air outlet, and the air guide mechanism can move to the middle of the air outlet (that is, the position between the first air outlet end and the second air outlet end), it can effectively The airflow that should flow to the end of the second tuyere is led out forward, effectively reducing the distance that the airflow flows downward, so it can effectively increase the distance blown forward, and can achieve long-distance air supply; Effectively reduce the airflow disturbance between this part of the airflow and the airflow flowing to the second tuyere end, so that the air flow from the air guide mechanism and the air flow from the second tuyere end are smoother, thereby further improving the air supply. Distance, and ultimately increase the air supply distance of the whole machine, improve the frontal blowing feeling, and improve user comfort.

As shown in Figure 1, the lower air outlet of the cabinet air conditioner with the lower air outlet is generally designed at the bottom of the decorative panel, and the air outlet generally needs to match the appearance of the decorative panel, so as to prevent the lower air outlet from damaging the overall appearance of the cabinet. .

The present disclosure designs a hanging type air guide mechanism for a cabinet-type air conditioner with double air ducts and an open lower air outlet. The air guide mechanism has two states and can realize two air guide modes of the lower air outlet. The open position of the type air guide mechanism will separate the air flow of the main and auxiliary air ducts, so that the air flow of the auxiliary air duct in the front cannot interfere with the air flow of the main air duct, which increases the air supply distance of the main air duct, and keeps the air flow of the auxiliary air duct in the auxiliary air duct. The outlet of the air duct is guided to the front of the cabinet, so that the air from the secondary air duct blows directly forward, and the air supply distance of the auxiliary air duct is also increased. The combination of the two can make the air supply distance of the lower air outlet and improve the whole machine. comfort;

When the air guide mechanism is in the retracted state, the obstruction of the air guide mechanism to the airflow in the air duct is reduced, and the air passes through the lower plate of the volute to form a diffused air supply state, which can significantly improve the cooling and heating rates in the area directly in front of the cabinet. Improve comfort.

There is also a human body position detector in front of the cabinet, including but not limited to a detection device equipped with infrared, sound waves, and image sensors to feed back the position of the human body. The detector detects the position of the area; the detector feeds back the user's position in real time, and the downwind outlet will adjust the air guiding state of the air guiding mechanism in real time according to the feedback, and adjust the air supply mode to improve the user's comfort.

In some embodiments, the air guide mechanism 3 can move to a first position range, so that the air guide mechanism 3 guides part of the airflow flowing to the second air port end 22 , and the air guide mechanism 3 also It can be moved to the second position range, so that the air guide mechanism 3 does not block and guide part of the air flow to the second air port end 22 . This is the preferred structural form and movement mode of the wind guide mechanism of the present disclosure, that is, when the wind guide mechanism moves to the first position range, it can block and guide the air flow, so as to effectively guide the wind forward. The first position range is preferably In order for the air guide mechanism to rotate to the lower position, as shown in Figure 2, when the air guide mechanism moves to the second position range, the blocking and diversion of the airflow can be cancelled. position, as shown in Figure 4, so that the airflow is blown out from the volute lower plate at the bottom of the air outlet, forming two different air outlet modes, that is, the long-distance forward air outlet and the forward width diffused air.

The downward flow distance (reduces the air volume flowing to the ground, thereby increasing the forward air outlet distance), increases the forward air supply distance, and at the same time makes the main air duct air flow more smoothly along the wind guide surface of the lower plate of the volute, making it The air supply distance is increased, thereby improving the air supply distance of the whole machine and improving the comfort. Judging from its speed cloud map and the actual test situation, the air supply from the downwind port is convergent and forward at this time, and the wind speed is fast, which can send cold and heat to the air conditioner. The area farther ahead; when the air guide mechanism is in the retracted state as shown in Figure 4, the obstruction of the air guide mechanism to the airflow in the air duct is reduced, so that the air outlet volume of the air duct is obviously increased. The wind structure can form a diffused air supply mode, which can quickly cool and heat the area in front of the cabinet, and improve the comfort of the local area. Judging from its speed cloud map and the actual test situation, the air supply from the downwind port is diffuse.
