[0046] Figure 1 This is a schematic structural diagram of a light-emitting device according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 5 This utility model provides a light-emitting device 300 for an air conditioner, including a lamp housing 310 and a light-emitting part 320. The front surface of the lamp housing 310 is recessed inward to form a groove extending along the length direction of the lamp housing 310. The light-emitting part 320 is disposed at the bottom of the groove. The light-emitting part 320 is a light-emitting strip extending along the length direction of the lamp housing 310.

[0047] The groove extends along the length of the lamp housing 310, and the light strip is installed at the bottom of the groove. The lamp housing 310 can protect and fix the light strip, making it less susceptible to damage from bumps. Moreover, the concave shape of the lamp housing makes the light strip more eye-catching when it is lit.

[0048] In some other embodiments of this utility model, the light-emitting part 320 includes a plurality of light-emitting strips arranged sequentially along the length direction of the lamp housing 310. The light-emitting part 320 includes a plurality of light-emitting strips, and the length of each light-emitting strip can be made relatively short, which can reduce the difficulty of manufacturing and installing the light-emitting strips.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the light-emitting device 300 also includes two clamping strips 330. Each clamping strip 330 extends along the length of the lamp housing 310. The two clamping strips 330 are disposed at the bottom of the groove, and the two clamping strips 330 are respectively located on both sides of the light-emitting part 320.

[0050] The clamping strip 330 can also protect the light-emitting strip, and the clamping strip 330 can also fix the light-emitting strip.

[0051] In some embodiments of this utility model, such as Figure 1As shown, the light-emitting device 300 also includes a light-emitting lamp 340. The light-emitting lamp 340 is disposed on the rear side of the recess. The light-emitting part 320 is configured to transmit the light generated by the light-emitting lamp 340. A through hole extending along the length direction of the lamp housing 310 is provided at the bottom of the recess. The light-emitting part 320 passes forward through the through hole from the inside of the lamp housing 310.

[0052] As a light source, the light-emitting lamp 340 generates light. The light is transmitted to the light-emitting part 320 and then transmitted out by the light-emitting part 320. The light-emitting part 320 passes forward through the through hole from the inside of the lamp housing 310. When the light-emitting lamp 340 emits light, the light is transmitted out through the through hole by the light-emitting part 320.

[0053] In other embodiments of this utility model, such as Figure 1 As shown, the light-emitting part 320 can also be provided at the through hole.

[0054] In some embodiments of this utility model, such as Figure 1 As shown, the lamp housing 310 defines a first mounting cavity with a rearward opening, located on the rear side of the recess. A portion of the light-emitting part 320 is located within the first mounting cavity. The light-emitting device 300 also includes a light-emitting lamp base 350. The light-emitting lamp base 350 is disposed at the opening of the first mounting cavity. The light-emitting lamp 340 is disposed inside the light-emitting lamp base 350.

[0055] The light source base 350 closes the opening of the first mounting cavity, and the light source 340 is installed inside the light source base 350, so that the light is transmitted forward to the light-emitting part 320.

[0056] In some embodiments of this utility model, such as Figure 1 As shown, the light-emitting part 320 includes a light-transmitting block 321 and two supports. The front end of the light-transmitting block 321 is located inside or through the through hole, and the light-transmitting block 321 is positioned in front of the light-emitting lamp 340. The two supports are respectively disposed on both sides of the light-transmitting block 321. The two supports contact and abut against the front surface of the first mounting cavity. A stop strip 311 is provided at the opening of the first mounting cavity, and the two supports also contact and abut against the two stop strips 311 respectively, so that the light-emitting part 320 is engaged in the first mounting cavity.

[0057] The light-emitting part 320 is snapped into the first mounting cavity, making its installation simple and secure. Two brackets that contact and abut against the side surface of the first mounting cavity ensure that the light-transmitting block 321 can be stably positioned.

[0058] In some embodiments of this utility model, such as Figure 1As shown, the lamp base 350 defines a second mounting cavity with an opening facing forward, and the lamp 340 is disposed within the second mounting cavity. The lamp base 350 is engaged with two brackets. A lamp cover 360 is provided at the opening of the second mounting cavity, and the lamp cover 360 is configured to transmit the light emitted by the lamp 340. The light transmitting block 321 contacts and abuts against the lamp cover 360.

[0059] The lamp base 350 is engaged with two brackets to secure it. The lamp 340, located in the second mounting cavity, emits light, which is transmitted to the lamp cover 360 and then to the light-transmitting block 321. The complete installation process involves inserting the light-transmitting block 321 of the light-emitting part 320 into the through hole and engaging the two brackets of the light-emitting part 320 onto the stop strip 311 on the lamp housing. At this point, the light-emitting part 320 is securely installed in the first mounting cavity. Then, the lamp base 350 is engaged with the two brackets to secure it at the opening of the first mounting cavity.

[0060] In some embodiments of this utility model, such as Figure 1 As shown, each bracket includes a first connecting plate 323 connected to the light transmission block 321, and a second connecting plate 324 connected to the first connecting plate 323. A light-emitting lamp base 350 is inserted between the two second connecting plates 324. A light-emitting lamp 340 located within the light-emitting lamp base 350 emits light, which is then transmitted to the light-emitting lamp cover 360 and then to the light-emitting part 320. This arrangement facilitates light transmission.

[0061] In some embodiments of this utility model, the bracket and the light transmission block 321 are made of the same material.

[0062] In some embodiments of this utility model, such as Figure 1 As shown, the light-emitting part is a light-diffusing strip, and the light-emitting lamp 340 is a strip-shaped light-emitting lamp. A light-diffusing strip is an optical element used to achieve uniform light distribution, ensuring that the front light looks soft and uniform. The light-emitting part 320 emits the light emitted by the strip-shaped light-emitting lamp 340 in a uniformly distributed manner, meeting the needs of various scenarios for light uniformity, efficiency and reliability.

[0063] In some other embodiments of this utility model, there are multiple light-emitting lamps 340, which are arranged sequentially at intervals along the length of the lamp housing 310. Clearly, the light-diffusing strip plays a more important role in uniformly distributing light; through the light-diffusing strip, the user ultimately sees the entire light-emitting part 320 emitting light uniformly, rather than multiple light-emitting lamps emitting light. The multiple light-emitting lamps 340 can be multiple LEDs; without the light-diffusing strip, LED leakage would occur.

[0064] In some embodiments of this utility model, such as Figure 1As shown, the two oppositely arranged groove walls are flat. The flat groove walls make the front surface of the lamp housing 310 look neat.

[0065] In some other embodiments of this utility model, the two oppositely arranged groove walls of the groove are provided with strip grooves or ridges extending along the length direction of the lamp housing 310.

[0066] This utility model embodiment also provides an indoor unit of an air conditioner, including a housing 100 and a light-emitting device 300 of any of the above embodiments, wherein the light-emitting device 300 is disposed on the housing 100.

[0067] The indoor unit of the air conditioner can be wall-mounted, cabinet-type, or column-type. When the indoor unit is wall-mounted, the light-emitting device 300 is installed horizontally. When the indoor unit is cabinet-type or column-type, the light-emitting device 300 is installed vertically.

[0068] In some embodiments of this utility model, such as Figures 2 to 4 As shown, a vertically extending mounting groove 103 is formed in the center of the front surface of the housing 100, and the light-emitting device 300 is disposed within the mounting groove 103. The light-emitting device 300 is inserted into the mounting groove 103 from top to bottom, and then fixed with a screw from both the top and bottom. Compared with the light-emitting device on the indoor unit of a cabinet air conditioner in the prior art, the length of the light-emitting part in this solution accounts for a larger proportion of the height of the indoor unit of the air conditioner, and it can be located in the center of the front surface of the housing, resulting in a more obvious lighting effect.

[0069] In some embodiments of this utility model, such as Figure 2 As shown, a mounting hole 104 is provided in the mounting groove 103, and the light-emitting device 300 is installed in the mounting groove 103 through the mounting hole 104.

[0070] In some embodiments of this utility model, such as Figure 5 As shown, air outlets are provided at the front ends of both side walls of the housing 100, and the air outlets extend vertically. Since the air outlets are located at the front ends of the two side walls of the housing 100, it is clear that the light-emitting device 300 and the air outlets do not interfere with each other.

[0071] In some embodiments of this utility model, such as Figure 5As shown, an air duct is provided inside the housing 100. The air duct includes a main air duct section 130, and a first air duct section 110 and a second air duct section 120 connected to the front end of the main air duct section 130. There are two air outlets, namely an air outlet 101 and an air outlet 102, which are respectively connected to the first air duct section 110 and the second air duct section 120. The main air duct section 130 includes a first air duct wall 131 and a second air duct wall 132 arranged opposite to each other. A cross-flow fan 140 is disposed inside the housing 100. The first air duct wall 131 is a volute tongue surface, and the second air duct wall 132 is a volute shell surface. The volute tongue surface has a volute tongue portion that cooperates with the cross-flow fan 140. The volute tongue portion, the volute shell surface, and the cross-flow fan 140 cooperate to work. The diversion device is located at the front end of the main air duct section 130. The diversion device is configured to guide and divert the airflow from the main air duct section 130 so that part of the airflow flows to the first air duct section 110 and the rest flows to the second air duct section 120.

[0072] The cross-flow fan 140 rotates, creating airflow between the volute tongue and the volute surface. This airflow passes through 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 delivery range and enabling ultra-wide-angle whole-house air delivery. When the airflow generated by the cross-flow fan 140 flows between the volute tongue and the volute surface, it is mainly concentrated on one side of the volute surface. By adjusting the airflow direction through the diversion device at the front end of the main air duct section 130, the flow rate of the air entering the first air duct section 110 and the second air duct section 120 can be adjusted, and the resistance of the airflow entering the first air duct section 110 and the second air duct section 120 can be reduced. Finally, the amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is adjusted accordingly, so that the total amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is equal or not much different, so that the air outlet of the indoor unit of the air conditioner is balanced from left to right, ensuring the horizontal air supply effect, and also ensuring the uniform temperature of the indoor space.

[0073] In some embodiments of this utility model, such as Figure 5 As shown, the airflow distribution device includes a first air distribution plate 910. The first air distribution plate 910 is curved. A portion of the first air distribution plate 910 is located within the main air duct section 130, and another portion is located within the second air duct section 120. The surface of the first air distribution plate 910 facing the second air duct wall 132 is a concave surface. The first air distribution plate 910 is used to guide a portion of the airflow from the main air duct section 130 into the second air duct section 120. By setting the first air distribution plate 910, the resistance to airflow from the main air duct section 130 into the second air duct section 120 can also be reduced.

[0074] In some embodiments of this utility model, such as Figure 5As shown, the flow distribution device also includes a second air distribution plate 920 and a third air distribution plate 930. The second air distribution plate 920 is curved. The second air distribution plate 920 is located on the side of the first air distribution plate 910 away from the second air duct wall 132, and the surface of the second air distribution plate 920 facing the first air distribution plate 910 is a concave surface. The curvature of the first air distribution plate 910 is greater than that of the second air distribution plate 920. The second air distribution plate 920 is located within the main air duct section 130. The third air distribution plate 930 is located on the side of the second air distribution plate 920 away from 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.

[0075] The second air distribution plate 920 divides the airflow from the main air duct section 130 into two approximately equal parts. One part of the airflow, guided by the surface of the second air distribution plate 920 facing the first air distribution plate 910, enters the second air duct section 120. The other part of the airflow, guided by the surface of the second air distribution plate 920 facing the third air distribution plate 930, enters the first air duct section 110. The third air distribution plate 930 facilitates the guidance of airflow into the first air duct.
