[0039] Figure 1This is a schematic structural diagram illustrating the installation of the housing and sealing strip of an indoor unit of an air conditioner according to an embodiment of the present invention. Figure 1 As shown, and with reference Figures 2 to 3 This utility model provides an indoor unit for an air conditioner with a sealed air outlet edge, including a housing and a sealing strip 400. An air outlet is provided on the housing. The sealing strip 400 is disposed at all edges of the air outlet.

[0040] Because the sealing strip 400 has good heat insulation properties, the cold air from the air outlet cannot be transferred to the housing at the edge of the air outlet through the sealing strip 400. This results in a less significant temperature drop in the housing at the edge of the air outlet, preventing condensation from forming due to the low temperature of the housing at the edge of the air outlet coming into contact with indoor air. These features improve user satisfaction with the indoor unit of the air conditioner.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, the sealing strip 400 is located at part of the edge of the air outlet.

[0042] In some embodiments of this utility model, the sealing strip 400 is disposed at the front edge of the air outlet. Since the indoor unit of the air conditioner is mostly used with the air outlet facing forward, the sealing strip 400 being disposed at the front edge of the air outlet can minimize the generation of condensate.

[0043] In some embodiments of this utility model, such as Figure 1 As shown, the indoor unit of the air conditioner also includes a slide plate 500. The slide plate 500 is slidably disposed at the air outlet and configured to open or close the air outlet. A sealing strip 400 is disposed at one edge of the air outlet extending along its length and is located on the sliding path of the slide plate 500 when the air outlet is closed. The slide plate 500 contacts the sealing strip 400 when the air outlet is closed.

[0044] The sliding plate 500 is slidably mounted at the air outlet, allowing it to open or close and guiding the airflow. When the air outlet is closed, the sliding plate 500 contacts the sealing strip 400, ensuring a tight seal and preventing dust ingress and cold air leakage. Furthermore, when the air outlet is closed, the sealing strip 400 helps eliminate gaps in the indoor unit, preventing dust and other foreign objects from entering through these gaps.

[0045] In some embodiments of this invention, the sealing strip 400 is a rubber strip manufactured by an extrusion process. In some embodiments, the length can reach 1827 mm.

[0046] In some embodiments of this utility model, such as Figure 2As shown, the sealing strip 400 includes a clamping portion and a cavity portion 420. The clamping portion has a clamping groove. The housing has a first insertion portion 151 that inserts into the clamping groove.

[0047] The first insertion part 151 is inserted into the clamping groove to install the sealing strip 400 onto the housing. The cavity part 420 is located on the side of the clamping part facing the air outlet. When the slide plate 500 closes the air outlet, the slide plate 500 slides to contact the cavity part 420. The cavity 421 plays a role in buffering and shock absorption, and can also reduce the abnormal noise when the slide plate 500 is closed.

[0048] In some embodiments of this utility model, such as Figure 2 As shown, the sealing strip 400 also includes a second insertion portion 440, which is connected to the cavity portion 420. The housing has a slot into which the second insertion portion 440 is inserted.

[0049] While the first insertion part 151 is inserted into the clamping groove, the second insertion part 440 is inserted into the slot. This arrangement makes the sealing strip 400 more securely installed on the housing.

[0050] In some embodiments of this utility model, such as Figure 2 As shown, the sealing strip 400 also includes a sealing sheet 430, which is connected to the side of the clamping portion opposite to the air outlet. The sealing sheet 430 is in contact with the surface of the housing.

[0051] The sealing sheet 430 can cover the installation gap of the sealing strip 400, making the appearance more aesthetically pleasing and preventing dust from entering the gap between the sealing sheet 430 and the housing.

[0052] In some embodiments of this utility model, such as Figure 2 As shown, a first slot 152 is provided on the first insertion part 151, and a snap-fit ​​structure 413 is provided on the wall of the clamping groove, which is inserted into the first slot 152. A second slot is provided on the wall of the slot, and a snap-fit ​​protrusion for inserting into the second slot is provided on the second insertion part 440 or the cavity part 420.

[0053] While the first insertion part 151 is inserted into the clamping groove, the snap-fit ​​structure is inserted into the first snap-fit ​​groove 152, and the snap-fit ​​protrusion is inserted into the second snap-fit ​​groove, so that the sealing strip 400 is snapped into the housing, which can ensure that the sealing strip 400 is more firmly installed in the housing.

[0054] In other embodiments of this utility model, such as Figure 2 As shown, a first slot 152 is provided on the first insertion part 151, and a snap-fit ​​structure is provided on the groove wall of the clamping groove, and the snap-fit ​​structure is inserted into the first slot 152.

When the sealing strip 400 needs to be installed, the first insertion part 151 of the support plate 150 is inserted into the clamping groove of the sealing strip 400, and the snap-fit ​​structure is inserted into the first snap-fit ​​groove 152, and the snap-fit ​​protrusion is inserted into the second snap-fit ​​groove, so that the sealing strip 400 is snapped into the support plate 150.

[0058] In some embodiments of this utility model, multiple hooks are provided on the rear surface of the support plate, and the hooks are hung on the air outlet frame 140. The hooks are simple in structure, easy to process, and also facilitate the installation of the support plate onto the air outlet frame.

[0059] In some embodiments of this utility model, a protrusion is provided at the lower end of the front surface of the support plate 150, and the lower end of the decorative plate 160 contacts the protrusion. The decorative plate 160 is connected to the front surface of the support plate by adhesive. Over time, the decorative plate 160 is prone to slowly sliding down under the influence of gravity. The protrusion can support the decorative plate 160, prevent it from sliding down, and ensure that the decorative plate 160 is installed securely.

[0060] In some embodiments of this utility model, such as Figure 2As shown, the clamping part includes a first clamping plate 411 and a second clamping plate 412. The first clamping plate 411 is disposed between the first insertion part 151 and the decorative plate 160. The snap-fit ​​structure is a snap-fit ​​strip connected to the inner edge of the first clamping plate 411. The second clamping plate 412 is disposed on the side of the first insertion part 151 facing the air outlet. The cavity part 420 is connected to the second clamping plate 412. The first clamping plate 411 and the second clamping plate 412 define a clamping groove.

[0061] In some embodiments of this utility model, such as Figure 1 As shown, the air outlet is located on the side wall of the casing and extends vertically. The vertical extension of the air outlet ensures that the airflow is evenly distributed across the entire height of the outlet, thus preventing temperature stratification within the room.

[0062] In some embodiments of this invention, the decorative panel 160 forms the front surface of the housing, and the sealing strip 400 is disposed at the front edge of the air outlet. The decorative panel 160 forms the front surface of the housing, giving the indoor unit of the air conditioner a good appearance.

[0063] In some embodiments of this utility model, such as Figure 3 As shown, there are two air outlets, namely the first air outlet 101 and the second air outlet 102. The two air outlets help to expand the air outlet angle of the indoor unit of the air conditioner.

[0064] In some embodiments of this utility model, such as Figure 1 As shown, there are two sealing strips 400, which are installed on both sides of the support plate 150.

[0065] In some embodiments of this utility model, such as Figure 1 As shown, there are two slide plates 500, which are respectively installed at the first air outlet and the second air outlet.

[0066] In some embodiments of this utility model, such as Figure 3As shown, the housing also includes a back frame 170, and an air outlet frame 140 connected to the back frame 170 and disposed on the front side of the back frame 170. The air outlet frame 140 and the back frame 170 define an air outlet duct. The air outlet duct has a main air outlet section 130, and a first air outlet section 110 and a second air outlet section 120 connected to the front end of the main air outlet section 130. The first air outlet section 110 is connected to a first air outlet 101, and the second air outlet section 120 is connected to a second air outlet 102. The change angle of the airflow direction from the main air outlet section 130 under the action of the second air outlet section 120 is greater than the change angle under the action of the first air outlet section 110. The indoor unit of the air conditioner also includes a flow diversion device, which is disposed at the front end of the main air outlet section 130. The flow diversion device is configured to guide and divert the airflow from the main air outlet section 130, so that part of the airflow flows to the first air outlet section 110, and the remaining part of the airflow flows to the second air outlet section 120.

[0067] The airflow passes through the main air duct section 130, then enters the first air duct section 110 and the second air duct section 120, and exits from the first air outlet 101 corresponding to the first air outlet 110 and the second air outlet 102 corresponding to the second air outlet 120. The first air outlet 101 and the second air outlet 102 are respectively located on two opposite side walls of the housing 100, increasing the air supply range and achieving ultra-wide-angle whole-house air supply. The flow distribution device adjusts the direction of the airflow, thereby adjusting the flow rate of the airflow entering the first air duct section 110 and the second air duct section 120, and correspondingly adjusting the amount of airflow exiting the first air outlet 101 or the second air outlet 102. The flow distribution device can adjust the amount of airflow exiting the first air outlet 101 or the second air outlet 102 to be equal. In particular, the change angle of the airflow direction in the main air duct section 130 under the action of the second air duct section 120 is greater than the change angle under the action of the first air duct section 110, so as to avoid the amount of airflow flowing out of the first air outlet 101 being significantly greater than the amount of airflow flowing out of the second air outlet 102.

[0068] In some embodiments of this utility model, such as Figure 3As shown, the air distribution device includes a first air distribution plate 910 and a second air distribution plate 920. The first air distribution plate 910 is curved, and the cross-section at the air outlet edge of the first air distribution plate 910 is a first cross-section.

The cross-section at the air outlet edge of the second air distribution plate 920 is a second cross-section. The cross-section at the air inlet edge of the second air distribution plate 920 is a fourth cross-section. The second air distribution plate 920 is located on the side of the first air distribution plate facing the second air duct section. The surface of the first air distribution plate 910 facing the second air distribution plate 920 is a concave surface, and the surface of the second air distribution plate 920 away from the first air distribution plate 910 is a concave surface. The included angle between the first and third cross-sections is greater than the included angle between the second and fourth cross-sections, so that the curvature of the second air distribution plate 920 is greater than that of the first air distribution plate 910. Part of the second air distribution plate 920 is located within the main air duct section 130, and another part is located within the first air duct section 110. The first air distribution plate 910 is located within the main air duct section 130, and the air outlet edge of the first air distribution plate 910 is close to the junction of the front air duct wall of the first air duct section 110 and the front air duct wall of the second air duct section 120.

[0069] In some embodiments of this utility model, such as Figure 3 As shown, the air distribution device also includes a third air distribution plate 930. The third air distribution plate 930 is disposed on the side of the second air distribution plate 920 opposite to the first air distribution plate 910. The third air distribution plate 930 is curved, and the surface of the third air distribution plate 930 facing the second air distribution plate 920 is a concave surface. The angle between the cross-section at the air outlet edge of the third air distribution plate 930 and the cross-section at the air inlet edge of the third air distribution plate 930 is greater than or equal to 160°. The third air distribution plate 930 facilitates the guidance of airflow into the first air distribution duct 110.
