[0047] In this application, "multiple" means two or more (including two).

[0048] An air conditioner can be constructed as a split-type air conditioner, which includes an outdoor unit (e.g., mounted on a building wall) that is placed outside the building and exchanges heat with the outside environment, and an indoor unit that is placed inside the building and exchanges heat with the indoor space to achieve indoor temperature regulation (heating up or cooling down).

[0049] An air conditioner indoor unit includes a frame, fan components and heat exchange components installed within the frame for air handling, and structural components such as panels and decorative strips installed on the frame.

[0050] The internal space is defined by multiple structural components such as the frame, panel, and decorative parts. The fan and heat exchange components are located inside the internal space. The frame also has an air outlet, and the air outlet has a guide component. The guide component is used to guide the airflow direction to realize functions such as different sweeping modes, different wind feeling modes, and zoned air supply.

[0051] However, there is a gap between the frame and the panel. During the process of the air guide component guiding the airflow, the airflow may flow back into the housing space through the gap between the frame and the panel, resulting in the interaction of hot and cold airflow in the housing space. This not only affects the temperature regulation effect and efficiency of the indoor unit of the air conditioner, but may also cause condensation in the area where the decorative strip is located, resulting in water dripping and affecting the user experience. Moreover, the phenomenon of hot and cold airflow convergence is particularly obvious in the indoor unit of the air conditioner with the windless mode.

[0052] In other words, for some air conditioner indoor units with a windless mode, the air guiding components achieve windless airflow in the air outlet area. For example, a large air guide plate and a small air guide plate are connected and matched. The large air guide plate is set with micro-holes to achieve windless airflow. During the airflow process, some airflow will be guided to the upper side of the air outlet according to the shape of the large air guide plate. In the gap area between the upper side frame and the panel of the air outlet, hot and cold airflows will converge. Not only will the airflow entering the containment space affect the temperature regulation effect and temperature regulation efficiency of the air conditioner indoor unit, but the condensation in the decorative strip area will also affect the user experience.

[0053] Based on this, this application proposes an indoor air conditioning unit that improves the sealing effect by separating the first gap between the front frame and the panel from the second gap between the front frame and the decorative strip. This improves the convergence of hot and cold air currents above the air outlet, not only enhancing the temperature regulation effect and efficiency of the indoor air conditioning unit, but also reducing the probability of condensation, thereby improving the user experience.

[0054] The following is for reference. Figures 1-13 Description of an indoor air conditioning unit 100 according to an embodiment of the present utility model.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, this application proposes an air conditioner indoor unit 100, including: a front frame 10, a panel 20, and a decorative strip 30.

[0056] The face frame 10 has an air outlet 111; the panel 20 is disposed on the face frame 10, the panel 20 is located above the air outlet 111, and the panel 20 and the face frame 10 form a first gap a1 opposite to each other in a first direction above the air outlet 111; the decorative strip 30 is connected to one end of the panel 20 adjacent to the air outlet 111, and the face frame 10 and the decorative strip 30 form a second gap a2 opposite to each other in a first direction above the air outlet 111, and the first gap a1 and the second gap a2 are spaced apart in a second direction that has an angle with the first direction.

[0057] Specifically, the frame 10 is generally a rectangular frame, and the interior of the frame 10 defines an accommodating space. One side of the frame 10 in the first direction is used to mount it on the interior wall of the building, and the other side of the frame 10 in the first direction is used to install the panel 20. The panel 20 can improve the overall aesthetics of the air conditioner indoor unit 100, and a filter can be installed between the panel 20 and the frame 10. The installation of the panel 20 makes the removal and cleaning of the filter easier. Brand logos, displays, and other structures can be installed on the panel 20 in specific areas. Furthermore, a decorative strip 30 can be installed between the panel 20 and the frame 10. The decorative strip 30 is placed at the end of the panel 20 near the air outlet 111 to cover the gap between the air outlet 111 and the panel 20, thereby further improving the aesthetics of the air conditioner indoor unit 100.

[0058] Understandably, to facilitate filter removal and cleaning, and to avoid interference between the faceplate 10 and the filter, a first gap a1 exists between the panel 20 and the faceplate 10. A decorative strip 30 can be provided on the end of the panel 20 in the second direction (the end of the panel 20 adjacent to the air outlet 111), forming a second gap a2 between the decorative strip 30 and the faceplate 10. The first gap a1 is defined by the faceplate 10 and the panel 20 being opposite and spaced apart in the first direction, and the second gap a2 is defined by the decorative strip 30 being opposite and spaced apart in the first direction. The first gap a1 and the second gap a2 are spaced apart in the first direction (in conjunction with...). Figure 4 This allows for a smaller flow rate of air from the outlet 111 upwards during the air guiding process, which then flows through the second gap a2 to the first gap a1, thereby improving the convergence of hot and cold air currents above the outlet 111.

[0059] It should be noted that during the process of heating the indoor air by the air conditioner indoor unit 100, the airflow from the air outlet 111 is hot air, which will mix with the cold airflow that is exchanging heat inside the containment space. This results in the temperature of the cold airflow that is exchanging heat with the heat exchange components being higher than the temperature of the indoor space, thus affecting the temperature regulation effect and efficiency. Conversely, during the process of cooling the indoor air by the air conditioner indoor unit 100, the airflow from the air outlet 111 is cold air, which will mix with the hot airflow that is exchanging heat inside the containment space. This results in the temperature of the hot airflow that is exchanging heat with the heat exchange components being lower than the temperature of the indoor space, thus affecting the temperature regulation effect and efficiency.

[0060] According to the embodiment of this application, the air conditioner indoor unit 100 can improve the convergence of cooling airflow above the air outlet 111 by separating the first gap a1 and the second gap a2. On the one hand, it reduces the airflow returning to the accommodating space, thereby reducing the impact of the returning airflow on the temperature regulation effect and temperature regulation efficiency of the air conditioner indoor unit 100 and improving the temperature regulation effect and temperature regulation efficiency. On the other hand, it can also reduce condensation in the area where the decorative strip 30 is located, thereby improving the user experience.

[0061] like Figure 4 As shown, according to some embodiments of this application, the face frame 10 and the decorative strip 30 form a third gap a3 in the second direction, the first gap a1, the third gap a3 and the second gap a2 are connected in sequence, and define a labyrinth seal a.

[0062] in, Figure 4 The dashed line in the middle illustrates the maze seal path a. It can be understood that the first gap a1 and the second gap a2 are defined by the panel 20 and the frame 10, and the frame 10 and the decorative strip 30, respectively, and both extend along the first direction. The third gap a3 is also defined by the frame 10 and the decorative strip 30, and the third gap a3 extends along the second direction, thus making the first direction and the second direction have an angle. The first gap a1, the second gap a2 and the third gap a3 can define a roughly "Z"-shaped maze seal structure a, which can improve the sealing effect between the frame 10, the decorative strip 30 and the panel 20, and reduce the airflow from the upper side of the air outlet 111 that flows back into the accommodating space through the first gap a1, so as to effectively improve the convergence of hot and cold air.

[0063] like Figure 4 As shown, according to some embodiments of this application, the gap size of the first gap a1 is smaller than the gap size of the second gap a2.

[0064] In other words, the gap between the panel 20 and the frame 10 above the air outlet 111 is smaller than the gap between the frame 10 and the decorative strip 30 above the air outlet 111, which can further improve the sealing effect of the labyrinth seal a and further reduce the probability of airflow flowing back into the internal accommodating space of the frame 10.

[0065] According to some embodiments of this application, the gap size of the first gap a1 is 0.1mm-0.5mm.

[0066] For example, the size of the first gap a1 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0067] In this way, on the one hand, the gap size of the first gap a1 can be avoided to be too small or even non-existent, thereby reducing the processing difficulty and effectively avoiding interference with the filter screen, thus effectively reducing the difficulty of disassembling the filter screen. On the other hand, the gap size of the first gap a1 can be avoided to be too large, thereby ensuring the sealing effect of the labyrinth seal a, effectively improving the convergence of hot and cold airflows, and enhancing the user experience.

[0068] According to some embodiments of this application, the gap size of the second gap a2 is 0.6mm-1.2mm.

[0069] For example, the size of the second gap a2 can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, etc.

[0070] Therefore, on the one hand, the second gap a2 can be avoided from being too small, so as to reduce the difficulty of disassembling and assembling the decorative strip 30; on the other hand, the second gap a2 can be avoided from being too large, so as to ensure the sealing effect of the labyrinth seal a, effectively improve the convergence of hot and cold air, and improve the user experience.

[0071] like Figure 5 , Figure 6 as well as Figure 7 As shown, according to some embodiments of this application, the face frame 10 includes: a face frame body 11 and a first protrusion 12. In a first direction, the first protrusion 12 is disposed at one end of the face frame body 11 adjacent to the air outlet 111. The panel 20 and the face frame body 11 define a first gap a1. The first protrusion 12 and the decorative strip 30 define a second gap a2 in the first direction and a third gap a3 in the second direction.

[0072] Specifically, the face frame 10 defines an air outlet 111, and the face frame 10 has a first protrusion 12 above the air outlet 111. The face frame body 11 can be formed on a first surface that is opposite to the panel 20 in a first direction. The first protrusion 12 can be formed on a second surface that is connected to the first surface and extends in a second direction, and a third surface that is connected to the second surface and parallel to the first surface. Thus, a first gap a1 is formed between the first surface and the panel 20, a third gap a3 is formed between the second surface and the panel 20 or the decorative strip 30, and a second gap a2 is formed between the third surface and the decorative strip 30.

[0073] In this way, not only can the structural strength of the face frame 10 be improved by setting the first protrusion 12, the first protrusion 12 can be formed as the assembly reference of the panel 20 and the decorative strip 30, improving the assembly accuracy and the fixing stability and reliability of the panel 20 and the decorative strip 30, but also the first protrusion 12 and the decorative strip 30 can cooperate to define the second gap a2 and the third gap a3 to form a labyrinth seal a, thereby improving the user experience of the air conditioner indoor unit 100.

[0074] like Figure 8 , Figure 9 and Figure 10 As shown, according to some embodiments of this application, the panel 20 includes: a panel body 21 and a second protrusion 22. In a first direction, the second protrusion 22 defines a first gap a1 with the face frame body 11, and the second protrusion 22 is used to connect with the decorative strip 30.

[0075] Specifically, the end of the panel body 21 away from the air outlet 111 can be pivotally connected to the face frame 10 so that the panel 20 can rotate relative to the face frame 10, thereby opening the face frame 10 on one side in the first direction to facilitate the removal of the filter. The end of the panel body 21 adjacent to the air outlet 111 can be provided with a second protrusion 22. The second protrusion 22 can have a fourth surface opposite to the first surface, and a second gap a2 is defined between the first surface and the second surface.

[0076] This not only improves the structural strength and reliability of the panel 20, but also the second protrusion 22 effectively reduces the gap between the end of the panel 20 near the air outlet 111 and the frame 10, thereby improving the sealing effect and improving the airflow recirculation above the air outlet 111.

[0077] Combination Figure 12 and Figure 13 As shown, according to some embodiments of this application, the decorative strip 30 includes: a first plate 31 extending in a first direction, a second plate 32 connected to the first plate 31 and extending in a second direction, the first plate 31 and the first protrusion 12 defining a third gap a3, and the side surface of the second plate 32 away from the face frame 10 being flush with the outer surface of the panel body 21.

[0078] Specifically, the end of the second plate 32 away from the air outlet 111 is connected to the first plate 31, and the first plate 31 is located below the second protrusion 22. The second plate 32 and the second surface of the first protrusion 12 are arranged opposite to each other to define the third gap a3. The side surface of the second plate 32 away from the face frame 10 is formed as a decorative surface and is flush with the outer surface of the panel body 21.

[0079] In this way, the decorative strip 30 defines a second gap a2 that communicates with the first gap a1 through the first plate 31, and further communicates with the third gap a3 to form a labyrinth seal a. The second plate 32 can be formed as a decorative surface to improve aesthetics. At the same time, it allows the decorative strip 30 to be spaced apart from the face frame 10 to facilitate the installation and removal of the decorative strip 30. It also makes the operation of synchronous rotation of the panel 20 and the decorative sleeve relative to the face frame 10 easier, thereby further reducing the difficulty of disassembling and cleaning the filter.

[0080] Combination Figure 11 and Figure 13 As shown, according to some embodiments of this application, a first connecting portion 34 is provided on the side of the first plate 31 facing the panel 20, and a second connecting portion 23 connected to the first connecting portion 34 is provided on the second protrusion 22 of the panel 20.

[0081] Specifically, a slot (i.e., a second connecting part 23) can be formed on the side of the second protrusion 22 facing the air outlet 111, and a plug-in part (i.e., a first connecting part 34) can be formed on the side of the first plate 31 facing the second protrusion 22. The plug-in part can be inserted into the slot, and multiple buckles can be provided on the plug-in part at intervals along its own length direction. A locking hole that engages with the buckles can be provided in the slot. In order to achieve the connection between the decorative strip 30 and the panel 20 by the simultaneous engagement of the buckles and the locking hole during the process of the first connecting part 34 extending into the second connecting part 23, the assembly stability and reliability of the decorative strip 30 on the panel 20 can be improved.

[0082] exist Figure 13 In the embodiments shown, according to some embodiments of this application, the decorative strip 30 further includes: a third plate 33 extending along a first direction, the third plate 33 and the first plate 31 being connected to the two ends of the second plate 32 in the second direction, and the free end of the third plate 33 and the first protrusion 12 defining a second gap a2, the first plate 31, the second plate 32 and the third plate 33 defining a cavity b communicating with the second gap a2.

[0083] Specifically, the first plate 31, the second plate 32, and the third plate 33 are connected in sequence, and the first plate 31 and the third plate 33 are arranged opposite each other in the second direction. The second plate 32 extends along the second direction and defines a second gap a2 through the third plate 33 to form a labyrinth seal a with the first gap a1 and the third gap a3. At the same time, it further defines a cavity b through the first plate 31, the second plate 32, and the third plate 33. The cavity b is also connected to the second gap a2. This not only allows the cavity b to form a weight-reducing groove to reduce the material cost of the decorative strip 30, but also allows the airflow from the air outlet 111 to converge in the cavity b to form turbulence. This can further suppress the backflow of the airflow from the air outlet 111 through the first gap a1 and further improve the sealing effect.
