Moreover, the air inlet 110c of the indoor unit 100 is generally located at the upper portion of the casing 110, and the front air outlet 110a is designed to increase the distance between the front air outlet 110a and the air inlet 110c, so as to prevent the air blown out from the front air outlet 110a from flowing back to the air inlet 110c and entering the indoor unit 100 from the air inlet 110c to affect the cooling/heating effect.

In addition, the indoor unit of the present embodiment has a front air outlet 110a and a lower air outlet 110b, and utilizes a fan 101 and a rotary partition 120 to supply air to one of the air outlets, during cooling, cold air can be blown out through the front air outlet 110a with a relatively high position, thereby avoiding discomfort caused by direct blowing of cold air to a human body, and utilizing the sinking tendency of cold air, the temperature of the whole indoor space can be rapidly and uniformly reduced, and during heating, hot air can be blown out through the lower air outlet 110b with a relatively low position, thereby directly blowing hot air to the ground, warming the legs and feet of a user, and utilizing the rising tendency of hot air to rapidly and uniformly raise the temperature of the whole indoor space, thereby improving the cooling/heating effect and improving the air supply experience of the user.

As well known to those skilled in the art, the indoor unit 100 generally further includes a heat exchanger 102, the casing 110 generally forms an air inlet 110c, and the heat exchanger 102 is disposed on an air inlet path between the air inlet 110c and the fan 101 to exchange heat with ambient air entering from the air inlet 110c, so as to form cold air during cooling and hot air during heating.

In this embodiment, the inlet 110c may be formed at the upper end of the casing 110, the casing 110 is generally a transversely extending strip-shaped structure, and the front outlet 110a and the lower outlet 110b are both transversely extending strip-shaped openings. The fan 101 may be a cross-flow fan with a transverse axis, the fan 101 is disposed at the air inlet of the air duct 130, and the fan 101 is configured to promote the airflow entering from the air inlet 110c to flow through the air duct 130 to the front air outlet 110a or the lower air outlet 110 b. The heat exchanger 102 may be a three-stage fin heat exchanger 102 covering the space above and in front of the fan 101.

As shown in fig. 1, the air duct 130 includes an upper air duct wall 131 and a lower air duct wall 132, the upper air duct wall 131 is bent upward and extends to the upper edge of the front air outlet 110a, the lower air duct wall 132 is bent forward and downward and extends to the rear edge of the lower air outlet 110b, when the rotary partition board 120 rotates to the first position, the rear end of the rotary partition board 120 abuts against the inner wall of the upper air duct wall 131, and when the rotary partition board 120 rotates to the second position, the rear end of the rotary partition board 120 abuts against the inner wall of the lower air duct wall 132. Therefore, by the cooperation of the rotary partition plate 120 with the upper air duct wall 131 and the lower air duct wall 132, the passage between the air duct 130 and the front air outlet 110a is isolated, or the passage between the air duct 130 and the lower air outlet 110b is isolated, so that air is supplied to one of the front air outlet 110a and the lower air outlet 110 b.

Meanwhile, the rotating partition 120 can guide the airflow to be blown out more smoothly. As shown in fig. 1 and 2, when the rotating partition 120 rotates to the second position, the rear end of the rotating partition 120 abuts against the inner wall of the lower wall 132 of the air duct, and the rotating partition 120 is inclined upward from the rear to the front, so that the air flow is guided upward and forward by the inclined rotating partition 120, and blown out from the front air outlet 110a through the air duct 130, which is beneficial for the air flow to the front air outlet 110a, and reduces the wind loss. As shown in fig. 3, when the rotating partition 120 rotates to the first position, the rear end of the rotating partition 120 abuts against the inner wall of the air duct upper wall 131, and the rotating partition 120 is arranged to be inclined downward from the rear to the front, so that the air flow is guided downward and forward by the inclined rotating partition 120, and is blown out from the lower air outlet 110b through the air duct 130, which is beneficial to the air flow flowing to the lower air outlet 110b, and reduces the wind loss.

In some embodiments, the front end of the rotating partition 120 may be directly pivoted to the inner wall of the front side of the casing 110, and the airflow is guided through the air duct 130 and the rotating partition 120 and blown out from the front outlet 110a or the lower outlet 110 b.

In some embodiments, a flow guiding block 111 protruding backward is formed or disposed on a position of the front inner wall of the casing 110 between the front outlet 110a and the lower outlet 110b, that is, the flow guiding block 111 separates the front outlet 110a from the lower outlet 110b, and the flow guiding block 111 may be integrated with or separated from the casing 110. The section of the casing 110 at the baffle 111 may be protruded forward relative to the section of the casing 110 at the front outlet 110a (as shown in fig. 1) or flush (as shown in fig. 4) to form two different shapes of indoor units 100.

The deflector 111 has an upper inclined section 111a extending upward and rearward from the rear and a lower inclined section 111b adjoining the rear end of the upper inclined section 111a and extending downward and forward, the front end of the rotating diaphragm 120 is rotatably connected to the junction of the upper inclined section 111a and the lower inclined section 111b, and the rotation axis of the rotating diaphragm 120 extends laterally. Therefore, the airflow can be guided to the front air outlet 110a in sequence by the rotary partition plate 120, the upper inclined section 111a and the air duct 130 which are located at the second position, so that the air outlet is increased smoothly, and the air loss is further reduced while the air outlet direction is improved by the airflow through three stages of air guide. Similarly, the rotating partition 120, the lower inclined section 111b and the air duct 130 at the first position can be used to guide the airflow to the lower air outlet 110b in sequence, so as to increase the smoothness of the air outlet, and the airflow passes through the three stages of air guiding, thereby improving the air outlet direction and further reducing the air loss.

Further, to improve the air outlet direction, as shown in fig. 2 and 3, a front air guiding plate 140 may be disposed at the front air outlet 110a, and one end of the front air guiding plate may be rotatably disposed at an upper edge of the front air outlet 110a and configured to rotate around a transversely extending shaft to open or close the front air outlet 110a, so that the front air guiding plate 140 guides the outlet air of the front air outlet 110a when the indoor unit 100 operates, thereby improving the air outlet direction, and the front air guiding plate 140 closes the front air outlet 110a when the indoor unit 100 stops, thereby maintaining the appearance and preventing dust from entering. In addition, since one end of the front air guiding plate 140 directly pivots to the upper edge of the front air outlet 110a, rather than to the rotating shaft in the air duct 130, when the front air guiding plate 140 closes the front air outlet 110a, the flash gap between the front air guiding plate 140 and the front air outlet 110a can be effectively reduced, so that the sealing performance of the front air outlet 110a is better.

During cooling, as shown in fig. 2, the rotary partition 120 may be controlled to rotate to the second position, and the front air guiding plate 140 is controlled to rotate to the horizontal position, so that cold air is blown into the environment from the front air outlet 110a, and then the shower-type air conditioner descends, thereby preventing the problem of direct blowing of cold air, and preventing the air from flowing back to the air inlet 110c at the top of the front air outlet 110a, and entering the indoor unit 100 from the air inlet 110c to affect the cooling effect.

Further, a lower wind deflector 150 may be disposed at the lower outlet 110b, as shown in fig. 2 and 3, and one end of the lower wind deflector is rotatably disposed at a front edge of the lower outlet 110b and configured to rotate around another transversely extending axis to open or close the lower outlet 110 b. The air outlet of the lower outlet 110b is guided by the lower air guide plate 150 when the indoor unit 100 is in operation, so as to improve the air outlet direction, and the lower outlet 110b is closed by the lower air guide plate 150 when the indoor unit 100 is stopped, so as to keep the appearance beautiful and prevent dust from entering. In addition, since one end of the lower air-guiding plate 150 is directly pivoted to the front edge of the lower air outlet 110b, rather than being pivoted to the rotating shaft in the air duct 130, when the lower air-guiding plate 150 closes the lower air outlet 110b, the flash gap between the lower air-guiding plate 150 and the lower air outlet 110b can be effectively reduced, so that the lower air outlet 110b has better sealing performance.

During heating, as shown in fig. 3, the rotary partition 120 can be controlled to rotate to the first position, and the lower air deflector 150 is controlled to rotate to the vertical position, so that hot air is blown from the lower air outlet 110b to the ground, and then the carpet-type air is rolled up, thereby warming the leg and foot regions of the user, simultaneously, rapidly and uniformly raising the temperature of the whole indoor space, and improving the air supply comfort of the user.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
