The specific meaning of the above terms in the present invention may be understood on a case by case basis by ordinary technical personnel in the field.

    [0024] The following part refers to Figures 1-8 to describe the indoor hanging unit 100 of the first embodiment of the present invention.

    [0025] As shown in Figures 1-8, the indoor hanging unit as specified in the embodiment of the present invention comprises body 1, air deflector 2, heat exchanger 3, and fan wheel 4.

    [0026] The air inlet 10a is formed at the top of body 1; air outlet 10b is formed on the front side in the lower part of body 1; front panel 11 is provided on the front side of body 1; baffle 10 is provided at the top of front panel 11; baffle 10 is positioned in front of air inlet 10a; one end of baffle 10 (for example, lower end in Figure 1 and Figure 3) is connected with the top of front panel 11; another end of baffle 10 (for example, upper end in Figure 1 and Figure 3) extends towards the direction far from air inlet 10a against front panel 11; baffle 10 and front panel 11 are integral forming parts. Here, it should be noted that "front side of body 1" denotes the side of indoor hanging unit 100 away from the wall surface.

    [0027] The air deflector 2 is provided at air outlet 10b to open and close air outlet 10b. When air deflector 2 opens upward air outlet 10b against front panel 11, the air flowing out of air outlet 10b can flow upward due to the action of air deflector 2. Heat exchanger 3 is provided inside body 1. Fan wheel 4 is also provided on the side of heat exchanger 3 far from air inlet 10a inside body 1.

    [0028] For example, as shown in Figure 1-8, the heat exchange duct, which is respectively connected with air inlet 10a and air outlet 10b, is defined in body 1. Heat exchanger 3 and fan wheel 4 may be provided inside the heat exchange duct. During the operation of indoor hanging unit 100, fan wheel 4 runs to form negative pressure at air inlet 10a. The air flows into the heat exchange duct via air inlet 10a, and driven by fan wheel 4 to exchange heat with heat exchanger 3. After heat exchange, the air flows out via air outlet 10b, so as to adjust the indoor temperature.

    [0029] The baffle 10 may be provided at the edge of front side in air inlet 10a; baffle 10 may extend along the left and right directions, so as to cover up body 1 and protect it from exposure, thus improve the overall appearance of indoor hanging unit 100 and realizing certain decorative effect. The lower end of baffle 10 may connect and fix with the top of front panel 11. The upper end of baffle 10 extends towards the direction far from air inlet 10a against front panel 11, so that the included angel between the extension direction of upper end of baffle 10 and the extension direction at the top of front panel 11 would exceed 0°. At such time, the upper end of baffle 10 can extend forward, extend backward, or extend vertically against the lower end of baffle 10 provided that: the upper end of baffle 10 extend towards the direction far from air inlet 10a against front panel 11, so that airflow on the surface of front panel 11 would not flow back to air inlet 10a. Here, it should be noted that "left and right directions" denote the left and right directions from the user when indoor hanging unit 100 is mounted on the wall and the user faces indoor hanging unit 100.

    [0030] The baffle 10 and the front panel 11 can be manufactured integrally. Baffle 10 is a part of front panel 11. Therefore, it's able to reduce the number of parts for indoor hanging unit 100, and improve the molding efficiency and assembly efficiency. For example, baffle 10 and front panel 11 can be processed integrally. Optionally, baffle 10 and front panel 11 can be cast integrally. It is appreciated that the present invention is not restricted to this. Alternatively, after front panel 11 has been processed, it is possible to further process front panel 11 to form baffle 10. Thus, front panel 11 and baffle 10 can be molded after being processed for two times. It can be understood that regardless of the processing sequence of baffle 10 and front panel 11, baffle 10 and front panel 11 should be of integral structure after the integral processing of indoor hanging unit 100.

    [0031] The air deflector 2 can be connected pivotally with body 1, so that air deflector 2 can turn to open and close air outlet 10b. When air deflector 2 closes air outlet 10b, air deflector 2 and front panel 11 transit smoothly to each other, thus ensuring pleasant appearance of indoor hanging unit 100, preventing the intrusion of dust in air into body 1 via air outlet 10b, and guaranteeing the heat exchange efficiency of indoor hanging unit 100. When air deflector 2 opens upward air outlet 10b against front panel 11, the air at air outlet 10b flows upward due to the action of air deflector 2. Then, the exit end of air deflector 2 can lean and extend upward, and indoor hanging unit 100 can run at the state of direct blow mode, breeze mode or wind-free mode, thus ensuring satisfactory comfort for the user. Due to the wall attachment effect of fluid, at least a part of airflow flows upward along the front surface of front panel 11. When the airflow reaches the top of front panel 11, because the upper end of baffle 10 extends towards the direction far from air inlet 10a against front panel 11, baffle 10 can block the airflow, so that the airflow will flow towards the direction far from air inlet 10a at the top of front panel 11. Therefore, it's able to prevent the airflow from flowing to the rear side of baffle 10 along front panel 11 and flowing back directly to air inlet 10a, avoid great temperature difference between air inlet 10a and indoor environment, thus ensuring the heat exchange efficiency of indoor hanging unit 100.

    [0032] In addition, during the operation of indoor hanging unit 100, because baffle 10 is positioned in front of air inlet 10a, and the upper end of baffle 10 extends towards the direction far from air inlet 10a against front panel 11, baffle 10 can better guide the air above indoor hanging unit 100 into air inlet 10a, thus increasing the air intake of indoor hanging unit 100.

    [0033] For the indoor hanging unit 100 according to the embodiment of the present invention, baffle 10 is provided at the top of the front panel 11 or in front of the air inlet 10a, and the another end of baffle 10 extends towards the direction far from air inlet 10a against front panel 11, so that baffle 10 can cover internal structure of body 1 and realize certain decorative effect, thus and improving the overall appearance of indoor hanging unit 100. Meanwhile, baffle 10 can stop the airflow blowing upward from air outlet 10b, so as to prevent the back flow and short circle, and guarantee the heat exchange efficiency of indoor hanging unit 100. Moreover, baffle 10 can guide the airflow at air inlet 10a to ensure the air intake of indoor hanging unit 100; by configuring baffle 10 and front panel 11 as integral forming parts, it's able to improve the molding efficiency and assembly efficiency of indoor hanging unit 100.

    [0034] In some specific embodiments of the present invention, as shown in Figures 1-3, the included angle between the upward extension direction of one end at the top of front panel 11 and the upward extension direction of another end of baffle 10 (for example, upper end in Figure 1 and Figure 3) is defined as "β", which meets the requirement of: 30°≤β≤100°. Therefore, it can prevent the failure of blocking the partial airflow blowing upward from air outlet 10b due to small included angle β between front panel 11 and baffle 10, avoid the collision between baffle 10 and airflow due to big included angle β. Thus, baffle 10 can better guide the airflow blowing upward from air outlet 10b, and further guarantee the air intake.

    [0035] Here, it should be noted that "included angle β" can be understood as the included angle between the upward extension direction of another end of baffle 10 and the tangential direction at the top of front panel 11. The tangential direction is generally identical with the direction towards air inlet 10a.

    [0036] Optionally, as shown in Figures 1-7, front panel 11 forms the arc structure protruding forward. Then, the front panel 11 may form an arc plate, thus further ensuring pleasant appearance for the indoor hanging unit 100.

    [0037] It is appreciated that the front panel 11 may form a flat plate structure. For example, as shown in Figure 8, front panel 11 may extend vertically; the upper end of baffle 10 may extend forward in curve against front panel 11; the included angle α between the extension direction and vertical direction of the upper end of baffle 10 can exceed 0°; the specific number of included angle α can be configured according to actual needs.

    [0038] In some embodiments of the present invention, as shown in Figures 1-3, baffle 10 can extend vertically or horizontally. At such time, in the horizontal direction, the upper end of baffle 10 is positioned on the rear side at the lower end of baffle 10, and the upper end of baffle 10 can be positioned on the rear side of at least partial front panel 11. That is to say, in the horizontal direction, the foremost position of indoor hanging unit 100 is located on front panel 11. Therefore, it can protect baffle 10 to some extent, and avoid the damage of baffle 10 due to collision during the movement, repair and installation of indoor hanging unit 100.

    [0039] It is appreciated that baffle 10 may extend vertically or lean and extend upward or forward.

    [0040] To be specific, along the direction from one end (for example, lower end in Figure 1 and Figure 3) of baffle 10 to another end (for example, upper end in Figure 1 and Figure 3) of baffle 10, the thickness of baffle 10 reduces gradually. Moreover, one end of baffle 10 is connected with the top of front panel 11, thus guaranteeing the reliable connection between baffle 10 and front panel 11, reducing the material amount of baffle 10, and cutting the costs.

    [0041] In some optional embodiments of the present invention, as shown in Figures 1-7, baffle 10 features flat plate structure, which is simple and easy to realize. At such time, front panel 11 may form an arc structure protruding forward, or form a flat plate structure, but are not limited to this.

    [0042] In other optional embodiments of the present invention, baffle 10 forms the arc structure protruding forward. For example, in Figure 8, the upper end of baffle 10 extends forward against front panel 11, so that baffle 10 can better guide the airflow at air inlet 10a, and guide the airflow blowing upward from air outlet 10b. Then, front panel 11 may form a flat plate structure, or an arc structure protruding forward, but are not limited to this.

    [0043] Optionally, the top surface of baffle 10 is lower than the top surface of body 1. Therefore, on the precondition of ensuring the pleasant appearance of indoor hanging unit 100, it's able to protect baffle 10 to certain extent, and prevent the damage of baffle 10 due to collision during the movement, repair and installation of indoor hanging unit 100.

    [0044] It can be understood that the top surface of baffle 10 can be parallel with the top surface of body 1, so as to ensure pleasant appearance for indoor hanging unit 100 and protect baffle 10.

    [0045] In some optional embodiments of the present invention, baffle 10 is longer than air inlet 10a in the horizontal direction. For example, as shown in Figure 1 and Figures 4-6, in the horizontal direction, baffle 10 is longer than air inlet 10a, thus further ensuring the covering effect of baffle 10. Therefore, the baffle 10 can better cover up the internal structure of body 1, protect the internal part of body 1 from exposure, and guarantee pleasant appearance for indoor hanging unit 100. It is appreciated that in the horizontal direction, baffle 10 can be longer than air inlet 10a, so as to ensuring the covering effect of baffle 10, and guaranteeing pleasant appearance for indoor hanging unit 100.

    [0046] Optionally, the color of baffle 10 can be identical with or different from the color of front panel 11. Therefore, the color of baffle 10 and front panel 11 can be configured according to the design needs, thus further improving the appearance of indoor hanging unit 100, and meeting the needs of different users. For example, spray coating and other processes can be adopted to make the color of baffle 10 different from the color of front panel 11. Therefore, the color of baffle 10 can better match with the color of front panel 11, thus improving the decorative effect of baffle 10.

    [0047] According to the present invention, extension plates 111 that extend backward are respectively provided at the top, left side and right side of front panel 11. The rear surface of each extension plate 111 is provided with front panel pivoting structure 112 that are connected pivotally with body 1. Baffle 10 is positioned between the two extension plates 111, and is respectively transitioned smoothly with the two extension plates 111. For example, as shown in Figures 4-7, two extension plates 111 can be provided symmetrically. The left end and right end of baffle 10 can respectively connect with and transit smoothly to extension plates 111, thus ensuring pleasant appearance for indoor hanging unit 100. Each front panel pivoting structure 112 may be provided with a pivotal axis. Two pivotal axes may extend horizontally towards each other. Each pivotal axis is connected pivotally with body 1, so that front panel 11 can rotate around the central axis of pivotal axis. When indoor hanging unit 100 needs to be repaired, front panel 11 can be opened directly to check the internal structure of body 1, thus facilitating the maintenance of indoor hanging unit 100.

    [0048] The air conditioner according to the second embodiment of the present invention includes indoor hanging unit 100 according to the first embodiment of the present invention.

    [0049] For the air conditioner according to the embodiment of the present invention, by adopting the indoor hanging unit 100, it's able to guarantee the heat exchange efficiency and, at the same time, improve the appearance, molding efficiency, and assembly efficiency of the air conditioner.

    [0050] For the air conditioner according to the embodiment of the present invention, its other compositions and operations are known to the ordinary technical personnel in the field, and will not be described in detail here.

    [0051] The following part refers to Figures 1-8 to describe the indoor hanging unit 100 of the embodiment in the present invention. It needs to be understood that the descriptions below are only illustrative, but do not provide specific restrictions for the present invention.

    [0055] The air deflector 2 is provided at air outlet 10b; air deflector 2 can be connected pivotally with body 1, so that air deflector 2 can rotate against body 1; the cross section of heat exchanger 3 is generally V-shaped; fan wheel 4 is provided below heat exchanger 3 inside body 1. Therefore, on the precondition of ensuring the heat exchange efficiency, it's able to reduce the space occupied by indoor hanging unit 100.

    [0056] As shown in Figures 1-3, air deflector 2 comprises first air deflector 21 and second air deflector 22. First air deflector 21 and second air deflector 22 can both form arc plates. First air deflector 21 can be turned to open and close air outlet 10b, and guide the airflow at air outlet 10b. Second air deflector 22 is provided on the internal side of first air deflector 21, and can rotate to guide the airflow at air outlet 10b. When first air deflector 21 closes air outlet 10b, first air deflector 21 protrudes and transits smoothly to front panel 11. When indoor hanging unit 100 is set at anti-direct blowing mode, breeze mode or wind-free mode, first air deflector 21 can rotate downward and open upward air outlet 10b against front panel 11. Then, second air deflector 22 rotates for certain degree, and the air (for example, the cold air after heat exchange) flows upward due to the action of first air deflector 21 and second air deflector 22. At such time, the first exit end 21a of first air deflector 21 can extend upward. Due to the wall attachment effect of fluid, at least part of the airflow can flow upward to the top of front panel 11 along the front surface of front panel 11. Baffle 10 can stop such part of airflow, so that such part of airflow can flow towards the direction far from air inlet 10a at the top of front panel 11. Therefore, it's able to prevent the back flow due to the direct back flow of airflow to air inlet 10a along front panel 11, avoid the decrease of temperature of air inlet 10a due to the cold air after heat exchange, and prevent the misguide of temperature sensor arranged at air inlet 10a, thus guaranteeing the heat exchange efficiency of indoor hanging unit 100.

    [0057] Here, it should be noted that the "internal" direction denotes the direction close to the center of indoor hanging unit 100. The direction opposite to the "internal" direction is defined as "external" direction. Wherein, the rotation angels and other parameters of first air deflector 21 and second air deflector 22 under different modes of indoor hanging unit 100 (including the anti-direct blowing mode, breeze mode and wind-free mode) can be configured according to actual applications, so as to better meet the demands of users.
