Figure 11 is a schematic diagram of the overall structure of a vertical air conditioner indoor unit 100 according to an embodiment of the utility model. Figure 2 1 is a schematic structural diagram of a lower decorative panel 120 and a lighting assembly 130 of a vertical air conditioner indoor unit 100 according to an embodiment of the utility model. Figure 3 1 is a schematic structural diagram of a lower decorative panel 120 of a vertical air conditioner indoor unit 100 according to an embodiment of the utility model. Figure 4 1 is a schematic structural diagram of a housing 131 and a light strip 133 of a vertical air conditioner indoor unit 100 according to an embodiment of the present invention. Figures 1 to 4 As shown, the vertical air conditioner indoor unit 100 of this embodiment may generally include: a front panel 110 , a lower decorative panel 120 and a lighting assembly 130 .

[0025] An air outlet 111 may be provided in the middle and upper part of the front panel 110. A lower decorative panel 120 may be arranged on the front panel 110 and below the air outlet 111. In addition, a step 121 may be provided on the lower back side of the lower decorative panel 120. The lighting assembly 130 may be arranged on the top surface of the step 121, and the lighting assembly 130 may include: a shell 131 and a light strip 133. The opening of the shell 131 faces downward, the light strip 133 is fixed to the inner side of the top surface of the shell 131 and the light-emitting surface of the light strip 133 faces downward, and the lower decorative panel area 126 below the light strip 133 is made of a light-transmitting material so that the light emitted by the light strip 133 is emitted through the lower decorative panel area 126 below it. The vertical air conditioner indoor unit 100 of this embodiment can provide an assembly solution for arranging a lighting assembly 130 within the limited space of the lower trim panel 120 of the exterior part, thereby achieving the purpose of the lighting assembly 130 occupying a small space, being simple to assemble, and having few parts, thereby effectively reducing the production cost of the vertical air conditioner indoor unit 100 and simplifying the assembly process.

[0026] like Figure 4 As shown, a protrusion 134 is provided on the inner side of the top surface of the housing 131 to fix the light strip 133 after hot melting. In a preferred embodiment, a plurality of protrusions 134 are provided, and are evenly arranged in the horizontal direction on the inner side of the top surface of the housing 131. In this way, the light strip 133 can be fixed more stably, and it is not easy to fall off, and the lighting and prompting effects of the light strip 133 are effectively guaranteed. Figure 4 The protrusions 134 shown are provided with 5, and it should be noted that the specific number of the protrusions 134 is only an example, and is not a limitation of the present invention. In some other embodiments, other numbers of protrusions 134 can also be provided according to actual conditions.

[0027] like Figures 2 to 4As shown, the left and right sides of the top surface of the step 121 are provided with first buckles 123 extending upward, and the left and right sides of the shell 131 are provided with corresponding first slots 135, so that the shell 131 is snapped with the lower decorative plate 120. The shell 131 is an integral part of the lighting assembly 130, and the shell 131 is snapped with the lower decorative plate 120, which actually connects and fixes the entire lighting assembly 130 with the lower decorative plate 120.

[0028] In a preferred embodiment, the rear sides of the two left and right first buckles 123 are both provided with limiting ribs 124 to limit the housing 131 in the front-to-back direction. The limiting ribs 124 located at the rear side of the first buckle 123 can extend upward from the top of the step 121, and by limiting the front-to-back direction of the housing 131, the accuracy of the assembly of the lighting assembly 130 can be ensured. The entire structure is scientifically and reasonably arranged, and the assembly process is effectively simplified. In addition, the limiting ribs 124 can also effectively prevent the appearance defects such as bending and deformation and shrinkage of the appearance parts of the indoor unit 100 of the vertical air conditioner, and effectively improve the aesthetics of the vertical air conditioner.

[0029] As mentioned above, the light strip 133 is fixed to the inner side of the top surface of the housing 131 by the hot-melted protrusion 134, thus completing the independent assembly of the lighting assembly 130 as a whole. After the lighting assembly 130 is assembled as a whole, the lighting assembly 130 as a whole can be connected to the lower trim panel 120 through the first buckle 123 and the first slot 135, providing an assembly solution for arranging the lighting assembly 130 in the limited space of the lower trim panel 120 of the appearance part, further simplifying the assembly process, saving manpower and material resources, and reducing production costs.

[0030] like Figure 2 and Figure 3 As shown, a third buckle 125 extending backward is provided on the back of the lower decorative plate 120 , and a corresponding third card slot (not shown in the figure) is provided on the front panel 110 to enable the lower decorative plate 120 to be snap-connected with the front panel 110 . Figure 2 , Figure 3 There are six third buckles 125 shown, and two third buckles 125 are located at the left and right sides of the upper part of the back of the lower decorative plate 120, two third buckles 125 are located at the left and right sides of the middle part of the back of the lower decorative plate 120, and two third buckles 125 are located at the left and right sides of the lower part of the back of the lower decorative plate 120. The specific distribution arrangement of the six third buckles 125 and the corresponding third buckles 125 can ensure that the connection between the lower decorative plate 120 and the front panel 110 is relatively stable, the force is relatively uniform, and the lower decorative plate 120 is not prone to bulging.

[0031] And, if Figure 2 and Figure 3As shown, the specific structures of the six third buckles 125 can be different, but the two third buckles 125 located on the left and right sides of the upper part of the back of the lower decorative plate 120 have the same structure, the two third buckles 125 located on the left and right sides of the middle part of the back of the lower decorative plate 120 have the same structure, and the two third buckles 125 located on the left and right sides of the lower part of the back of the lower decorative plate 120 have the same structure. Correspondingly, the six third slots of the front panel 110 are also arranged corresponding to the specific structures of the six third buckles 125, so that each pair of the third buckles 125 and the third slots can be accurately and firmly connected.

[0032] In addition, if Figure 2 and Figure 3 As shown, the two third buckles 125 at the bottom are respectively located at the rear sides of the left and right limiting ribs 124. The front and rear position distribution of the first buckle 123, the limiting rib 124, and the third buckle 125 can further improve the stability here, thereby improving the overall structural strength of the lower decorative plate 120 and extending the service life. It should be noted that the specific number of the third buckles 125 is only an example, and is not a limitation of the present invention. In some other embodiments, other numbers of third buckles 125 can also be set according to actual conditions.

[0033] In a preferred embodiment, the housing 131 is made of a non-light-transmitting material, so that all the light emitted by the light strip 133 can be emitted through the lower trim area 126 below it. The lower trim area 126 below the light strip 133 is made of a light-transmitting material, and the housing 131 is made of a non-light-transmitting material, so that all the light emitted by the light strip 133 arranged on the inner side of the top surface of the housing 131 can be emitted through the lower trim area 126 below it, without light leakage due to the housing 131. In a specific embodiment, the light-transmitting material of the lower trim area 126 below the light strip 133 can be PC, PS, or PMMA.

[0034] In a specific embodiment, in order to simplify the processing technology, the entire lower trim panel 120 can be made of translucent material, but the other areas except the lower trim panel area 126 below the light strip 133 can be sprayed to make other areas opaque, and only the lower trim panel area 126 below the light strip 133 is translucent. While further ensuring the illumination effect of the light strip 133, it can also avoid problems such as complicated processing technology caused by using different materials to make the lower trim panel 120.

[0035] More preferably, the lower trim area 126 below the light strip 133 can be frosted, so that the light emitted by the light strip 133 can be scattered into light with different angles after passing through the lower trim area 126 below it. In some other embodiments, the light diffusion effect can also be achieved by controlling the thickness of the lower trim area 126 below the light strip 133 or controlling the cooling speed during the molding process of the material of the lower trim area 126 below the light strip 133. The light emitted by the light strip 133 can be scattered into light with different angles after passing through the lower trim area 126 below it, so that the user can feel the lighting and prompting effects of the light strip 133 in different directions.

[0036] More preferably, if Figure 3 and Figure 4 As shown, the front sides of the housing 131, the light strip 133 and the top surface of the step 121 are all matched to be arc-shaped to expand the illumination range of the light strip 133. The housing 131, the light strip 133 and the top surface of the step 121 are all matched to be arc-shaped, and the arc is convex forward, which can make the illumination range of the light strip 133 wider and the illumination direction more forward, and can further enhance the lighting and prompting effects of the light strip 133.

[0037] In addition, in a preferred embodiment, the light strip 133 can change different colors of light, and change different colors in different scenes, which can serve as a prompt for the user and enhance the sense of technology and user experience of the vertical air conditioner indoor unit 100. For example, when the vertical air conditioner indoor unit 100 is running in cooling mode, the light strip 133 can display blue light; when the vertical air conditioner indoor unit 100 is running in heating mode, the light strip 133 can display orange light; when the vertical air conditioner indoor unit 100 fails, the light strip 133 can display red light. It should be noted that the specific colors and corresponding specific scenes displayed by the above-mentioned light strip 133 are only examples, and are not limitations of the present utility model. In some other embodiments, other colors can be set for different specific scenes according to actual conditions.

[0038] The vertical air conditioner indoor unit 100 of this embodiment can provide an assembly solution for arranging the lighting assembly 130 in the limited space of the lower decorative plate 120 of the exterior part, so as to achieve the purpose of the lighting assembly 130 occupying a small space, being simple to assemble, and having few parts, effectively reducing the production cost of the vertical air conditioner indoor unit and simplifying the assembly process. The specific structural setting and position setting of the lighting assembly 130 make it possible for the user to not directly see the light strip 133, but only feel the light emitted by the light strip 133, effectively improving the sense of technology and aesthetics of the vertical air conditioner indoor unit 100.

[0039] In a specific embodiment, the indoor unit of the vertical air conditioner may include: a housing 140, the housing 140 may include the front panel 110 and the lower decorative panel 120 mentioned above, and a cavity (not shown in the figure) is defined inside the housing 140. In addition, the housing 140 may also include a rear panel (not shown in the figure), and an air inlet may be provided on the rear panel to allow external air to enter the cavity. An air inlet grille may be provided at the air inlet to initially filter the air entering the cavity through the air inlet to prevent excessive dust and other impurities from entering the cavity.

[0040] In addition, the housing 140 may further include panels such as a top plate and a base, wherein the arrangement of the top plate and the base may make the vertical air conditioner indoor unit 100 more integrated and more stable when the vertical air conditioner indoor unit 100 is arranged in an indoor environment. In a specific embodiment, the front panel 110 and the rear panel of the vertical air conditioner indoor unit 100 may be directly connected without additionally arranging a side panel. Or in some other embodiments, the housing 140 may further include a side panel, and the side panel may include a left side panel and a right side panel, which are respectively connected to the front panel 110 and the rear panel.

[0041] The vertical air conditioner indoor unit 100 may further include: a heat exchanger (not shown in the figure), which is arranged in the cavity and configured to perform heat exchange on the air entering the cavity. It should be noted that the vertical air conditioner indoor unit 100 will produce condensed water during refrigeration. Specifically, during the refrigeration process of the vertical air conditioner indoor unit 100, the refrigerant absorbs the heat in the room and discharges it to the outside through the process of compression and expansion, thereby achieving cooling of the indoor environment. In this process, the refrigerant will become a low-temperature and low-pressure state. At this time, it will absorb the heat in the room through the heat exchanger as an evaporator, and also absorb the water vapor in the air. After the refrigerant absorbs the heat and water vapor in the room, it will become a high-temperature and high-pressure state, and then discharge these heat and water vapor to the outside through the condenser. In this process, due to the difference in temperature inside the vertical air conditioner indoor unit 100, the water vapor will condense into water droplets between the heat exchanger and the condenser, that is, condensed water is formed.

[0042] Therefore, in a specific embodiment, the vertical air conditioner indoor unit 100 may further include: a water receiving pan, which may be arranged at the heat exchanger and configured to collect and receive condensed water. It is necessary to provide a water receiving pan, which can avoid problems such as dripping in the vertical air conditioner indoor unit 100 and can also ensure the working reliability of the heat exchanger. In addition, the vertical air conditioner indoor unit 100 may further include: a drain pipe (not shown in the figure), which is configured to discharge the condensed water in the water receiving pan to the outside of the vertical air conditioner indoor unit 100, so as to avoid the condensed water from affecting the indoor environment.

[0043] The heat exchanger can be arranged in the cavity near the air inlet, and the shape of the heat exchanger can be arranged to match the air inlet, so that the air entering the cavity through the air inlet can be completely heated by the heat exchanger, thereby improving the heat exchange efficiency. After the air enters the cavity through the air inlet, it is heated by the heat exchanger and then sent to the indoor environment through the air outlet 111 of the front panel 110.

[0044] When the indoor unit 100 of the vertical air conditioner operates in the cooling mode, the air heated by the heat exchanger is cold air, which can lower the temperature of the indoor environment after being sent to the indoor environment through the air outlet 111, making the user feel cool. When the indoor unit 100 of the vertical air conditioner operates in the heating mode, the air heated by the heat exchanger is hot air, which can raise the temperature of the indoor environment after being sent to the indoor environment through the air outlet 111, making the user feel warm.

[0045] In a specific embodiment, the vertical air conditioner indoor unit 100 can turn on the cooling mode or the heating mode after receiving a start trigger signal from the user. More specifically, the start trigger signal sent by the user through a display device, a voice device, a remote controller, or a mobile terminal bound to the vertical air conditioner indoor unit 100 can be received. The mobile terminal can be a smart device that is easy to move, such as a smart phone, a tablet computer, etc.

[0046] In addition, an air supply fan (not shown in the figure) can also be provided in the cavity inside the casing 140, which is located in front of the heat exchanger. The air after heat exchange in the heat exchanger can be sent to the indoor environment through the air outlet 111 through the air supply fan. The fan of the vertical air conditioner indoor unit 100 can mainly include three types: centrifugal, cross-flow and axial flow. Among them, the air in the centrifugal fan is subjected to the centrifugal force, and a vacuum is generated in the center of the impeller. The inhaled air is turned 90° at the impeller inlet and enters the flow channel formed by the blades, and obtains kinetic energy and pressure energy under the action of the blades. The airflow thrown out from the blade channel enters the volute, and after being concentrated and guided, it is discharged from the outlet of the centrifugal fan.

[0047] A cross-flow fan can also be called a cross-flow fan. The airflow enters the blade grid radially from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow. The airflow in the axial flow fan flows axially inside the impeller. The above three types of fans each have advantages and disadvantages and can be set according to actual conditions. However, no matter which type of fan is used, the air after heat exchange in the heat exchanger can be sent to the indoor environment through the air outlet 111 to adjust the temperature of the indoor environment.

[0048] The air supply fan may also be provided with a corresponding motor, configured to drive the air supply fan to rotate. And the air supply speed of the vertical air conditioner indoor unit 100 can be adjusted by adjusting the speed of the motor driving the air supply fan. In a preferred embodiment, the air supply fan may be a cross-flow fan. This is because the axial length of the cross-flow fan is not limited, and the length of the impeller can be arbitrarily selected according to different usage needs. In addition, the air flow flows through the impeller and is affected by the blades twice, so the air flow can reach a long distance and the air supply is relatively far. In addition, the cross-flow fan has no turbulence, uniform air output, and low noise, which can effectively improve the user experience.

[0049] In a specific embodiment, the air outlet 111 may also be provided with a horizontal swing blade and a vertical swing blade (neither of which is shown in the figure). The vertical swing blade may be configured to adjust the left and right air outlet direction at the air outlet 111, and the horizontal swing blade may be configured to adjust the up and down air outlet direction at the air outlet 111. In a specific embodiment, the horizontal swing blade and the vertical swing blade are configured to adjust the specific posture according to the air supply mode. For example, the air supply mode may include a plurality of different air supply instructions, and the horizontal swing blade and the vertical swing blade may adjust the specific posture according to different air supply instructions.

[0050] More specifically, the specific postures of the vertical swing blades may include facing left, facing center, and facing right. The specific postures of the transverse swing blades include facing upward, facing center, and facing downward. In a preferred embodiment, the transverse swing blades and the vertical swing blades can also adjust the specific angles of the air outlet to achieve different air outlet volumes. For example, the vertical swing blades may have different air outlet angles when facing left. The transverse swing blades may have different air outlet angles when facing upward.

[0051] As for the specific posture of the horizontal swing blade, it should be noted that the horizontal swing blade faces upward, so that the vertical air conditioner indoor unit 100 can discharge air upward, which is more suitable for the case where the vertical air conditioner indoor unit 100 operates in the cooling mode. Since the vertical air conditioner indoor unit 100 delivers cold air in the cooling mode, according to the characteristics of the cold air, it will gradually sink after being blown upward, so that the temperature of the entire indoor environment can be reduced. Cold air direct blowing prevention can also effectively prevent users from having headaches, colds, etc.

[0052] The horizontal swing blades face downward, so that the vertical air conditioner indoor unit 100 can discharge air downward, which is more suitable for the vertical air conditioner indoor unit 100 to operate in the heating mode. Since the vertical air conditioner indoor unit 100 delivers hot air in the heating mode, according to the characteristics of hot air, it will gradually rise after being blown downward, so that the temperature of the entire indoor environment can be increased. The hot air blowing downward can also be blown to the user more effectively, making the user feel warm and comfortable.

[0053] As mentioned above, the light strip 133 can change different colors of light and change different colors in different scenes. According to the specific operation mode and swing blade posture of the vertical air conditioner indoor unit 100, the light strip 133 can emit different forms of light. For example, when the vertical air conditioner indoor unit 100 is operating in the cooling mode, the horizontal swing blade is facing upward, so that the vertical air conditioner indoor unit 100 can achieve upward air discharge, the light strip 133 can emit blue light and achieve a breathing effect by controlling the brightness of the light to gradually increase or decrease. When the vertical air conditioner indoor unit 100 is operating in the heating mode, the horizontal swing blade is facing downward, so that the vertical air conditioner indoor unit 100 can achieve downward air discharge, the light strip 133 can emit orange light and achieve a breathing effect by controlling the brightness of the light to gradually increase or decrease.

[0054] When the vertical air conditioner indoor unit 100 fails, the light strip 133 can flash red light at a preset frequency. Preferably, the vertical air conditioner indoor unit 100 can also be provided with a sound device, which can emit a prompt sound in conjunction with the flashing red light of the light strip 133, or send information through a mobile terminal bound to the vertical air conditioner indoor unit 100 to promptly remind the user. It should be noted that the specific color, mode and corresponding specific scene of the light strip 133 are only examples, and are not limitations of the present utility model. In some other embodiments, other colors and light emission modes can be set for different specific scenes according to actual conditions.

[0055] In addition, an air outlet guide plate (not shown in the figure) may be provided at the air outlet 111, configured to open and close the air outlet 111. When the air outlet guide plate opens the air outlet 111, the wind guided by the horizontal swing blade and the vertical swing blade can be sent to the indoor environment. If the air outlet guide plate closes the air outlet 111, no wind will be blown out of the air outlet 111. Generally, when the indoor unit 100 of the vertical air conditioner is closed, the air outlet guide plate can be made to close the air outlet 111 to prevent external dust from entering the inside of the casing 140 through the air outlet 111, thereby effectively ensuring the cleanliness of the inside of the casing 140.
