[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] In the related art, for embedded air conditioners, such as duct units, ceiling units and other equipment, the refrigerant pipes of the air conditioners are above the panel. Condensation may form on the refrigerant pipes of the indoor units, especially ceiling units, during operation, and the water drips down. However, a display panel is generally provided on the panel of the embedded air conditioner. If water drops fall on the area of ​​the display panel, it is easy to cause water corrosion on the display panel, thereby affecting the normal operation of the display panel.

[0035] For the above situation, please see Figure 1 In the first aspect of the present application, an air conditioner indoor unit 1 is provided. In the embodiment of the present application, the air conditioner indoor unit 1 includes a main body 10 and a panel structure 20, and the panel structure 20 is arranged at the bottom of the main body 10. The panel structure 20 is connected to the main body 10 in a detachable manner, such as screw connection, clamp connection, etc., to facilitate the installation and maintenance of various internal components.

[0036] See also Figure 1-Figure 3 The panel structure 20 includes a panel 30 and a display assembly 40. The panel 30 is connected to the bottom of the main body 10. The panel 30 is provided with a drain port 31 (such as Figure 6The display assembly 40 is connected to the panel 30, and the display assembly 40 includes a box body 41, which is arranged on the panel 30. The box body 41 has a side facing the main body 10 and is formed as a guide surface 411 with a slope. The guide surface 411 is used to guide the condensed water dripping from the main body 10 to the display assembly 40 to the drain outlet 31.

[0037] Specifically, when the air conditioner indoor unit 1 is a ceiling unit, in an indoor installation environment, a mounting opening is provided on the ceiling, the panel 30 covers the mounting opening, the main body 10 is located above the panel 30, and a valve (such as Figure 1 As shown in the figure, the valve is connected to the refrigerant pipe, the refrigerant in the main body 10 flows through the valve and the refrigerant pipe, the temperature difference between the inside and outside of the refrigerant pipe is large, and condensation water is easily generated on the outer surface of the refrigerant pipe. When condensation water drips down from the refrigerant pipe of the main body 10, the water will drip onto the panel 30 and the guide surface 411 of the box body 41, and finally discharged from the drain port 31. Among them, electronic components such as display lamp beads and display board 42 can be arranged in the box body 41.

[0038] It should be noted that the embodiment of the present application sets a guide surface 411 with a slope on the side of the box body 41 facing the main body 10, so that the water dripping onto the guide surface 411 can flow downward along the slope of the guide surface 411 in the direction of the drain outlet 31, so as to guide the water on the box body 41 to the drain outlet 31, reduce the accumulation of water in the box body 41, and reduce the possibility of water entering the box body 41. The setting of the guide surface 411 is used to guide the direction of the water flow, prevent the water from flowing around and causing water to enter the box body 41 and affect the various functional components inside, such as the display panel 42, lamp beads and other electronic components, causing damage, which is beneficial to the operating safety of the electronic components in the box body 41.

[0039] Among them, the guide surface 411 has a slope. Exemplarily, the guide surface 411 can be a complete slope, which extends obliquely from the direction away from the drain outlet 31 to the direction close to the drain outlet 31; or, the guide surface 411 can be composed of multiple slopes, and the inclination directions of the multiple slopes are the same, but the inclination angles are different; or, the guide surface 411 can also be an arc surface, the highest point of the arc surface is set away from the drain outlet 31, and the lowest point of the arc surface is set close to the drain outlet 31. Of course, the guide surface 411 can also be other types of surfaces with a slope, and there is no specific limitation here.

[0040] In some embodiments, the panel 30 has a central axis, and the drain port 31 is located on the central axis of the panel 30, so that the distance from the drain port 31 to each position is minimized as much as possible, so that water from each part of the panel 30 can be discharged from the drain port 31. Condensation water dripping from the main body 10 flows toward the drain port 31 on the panel 30, and the display assembly 40 is arranged close to the side edge of the panel 30, thereby reducing the amount of water flowing around the display assembly 40, thereby reducing the risk of water entering the box body 41.

[0041] See also Figure 3-Figure 4 In some embodiments of the present application, the side of the box body 41 facing the main body 10 is formed as an inclined guide surface 411, the guide surface 411 is inclined along the first direction L1, and the guide surface 411 is inclined along the second direction L2. The first direction L1 and the second direction L2 are both set at an angle to the horizontal plane, and the first direction L1 is perpendicular to the second direction L2.

[0042] Specifically, the drain port 31 is located at one side of the box body 41, and the guide surface 411 is inclined toward the drain port 31, so as to guide the water on the guide surface 411 to the drain port 31. Figure 4-5 As shown, the box body 41 is a rectangular parallelepiped, with the height direction of the box body 41 as the vertical Z axis, the length direction of the box body 41 as the X axis, and the width direction of the box body 41 as the Y axis, that is, the plane where the X axis and the Y axis are located is the horizontal plane. Figure 5 As shown in (a), the first direction L1 is located in the plane where the X-axis and the Z-axis are located, and the first direction L1 is set at an angle with the X-axis; Figure 5 As shown in (b), the second direction L2 is located in the plane where the Y axis and the Z axis are located, and the second direction L2 is set at an angle with the Y axis, such as Figure 5 As shown in (c), the guide surface 411 is inclined along the first direction L1 and the second direction L2. At this time, the lowest point on the guide surface 411 is close to the drain outlet 31, thereby further enabling the guide surface 411 to better perform the diversion function, reducing the amount of water flowing from the guide surface 411 to other positions, so that most of the water can flow directly along the guide surface 411 toward the drain outlet 31.

[0043] Among them, the angle between the first direction L1 and the horizontal plane determines the inclination angle of the guide surface 411 along the first direction L1, and the angle between the second direction L2 and the horizontal plane determines the inclination angle of the guide surface 411 along the second direction L2. The specific inclination angle of the guide surface 411 can be selected and set according to actual conditions, and the embodiment of the present application does not limit this.

[0044] For further information, see Figure 3 and Figure 6In some embodiments of the present application, the drain outlet 31 is located on one side of the box body 41 along the second direction L2, and a baffle 412 extending along the second direction L2 is provided on one side of the box body 41, and the baffle 412 is located at the inclined bottom end of the guide surface 411 along the first direction L1.

[0045] Among them, the drain outlet 31 and the box body 41 are arranged along the second direction L2, and the guide surface has an inclination in both the first direction L1 and the second direction L2, so the water droplets on the guide surface may flow to the inclined bottom end of the first direction L1, and may also flow to the inclined bottom end of the second direction L2. In order to make the flow direction of the water droplets more fixed, this embodiment sets a baffle 412 extending along the second direction L2 at the inclined bottom end of the guide surface 411 along the first direction L1, so that the water droplets flowing to the inclined bottom end of the first direction L1 can also flow along the extension direction of the baffle 412 to the inclined bottom end of the second direction L2, thereby further strengthening the guiding effect of the guide surface 411 on the flow direction of the water droplets.

[0046] For further information, see Figure 6 In some embodiments of the present application, a drainage channel 32 is provided on the panel 30 , one end of the drainage channel 32 is close to the inclined bottom end of the guide surface 411 , and the other end of the drainage channel 32 is close to the drain port 31 .

[0047] Specifically, the drain port 31 is arranged near the middle of the panel 30 to facilitate drainage of the panel 30, and the box body 41 is arranged near the edge of the panel 30 to reduce the accumulation of water on the panel 30 in the box body 41, so the drain port 31 and the box body 41 are arranged at intervals, and water drops flow toward the drain port 31 on the guide surface 411 of the box body 41. When the water drops flow from the guide surface to the panel 30, the water can flow to the drain port 31 through the drainage channel 32, thereby preventing the water from flowing down from the guide surface and then flowing around on the panel 30. Among them, the drainage channel 32 can be formed by enclosing a long strip plate-like structure.

[0048] In some embodiments of the present application, a curved surface is provided on the side of the panel 30 facing the main body 10, and the drain outlet 31 is located at the lowest point of the curved surface along the vertical direction, thereby facilitating water droplets to flow toward the drain outlet 31 on the panel 30, further improving the water accumulation on the panel 30.

[0049] In some embodiments, a bottom wall may be provided on the side of the box body 41 facing the panel 30, and water droplets dripping from the refrigerant pipe of the main body 10 may flow to the drain port 31 under the guidance of the guide surface 411, thereby reducing water accumulation in the box body 41. The bottom wall may further block water from entering the box body 41 from the junction of the box body 41 and the panel 30, and at the same time, may better install the functional components inside the box body 41.

[0050] Of course, see Figure 7In some embodiments of the present application, an opening 413 may also be provided on the side of the box body 41 facing the panel 30, and the opening 413 is away from the guide surface 411, and the water drops dripping from the refrigerant pipe of the main body 10 can flow downward along the slope of the guide surface 411 toward the drain outlet 31, so as to guide the water on the box body 41 to the drain outlet 31. At the same time, there is a display window on the panel 30, and there are functional components inside the box body 41, such as display lamp beads. The display lamp beads can be connected to the outside through the opening 413 on the box body 41 and the display window on the panel 30, so that the user can observe the information on the display lamp beads from the outside; if other functional components are also provided in the box body 41, such as the display panel 42, the opening 413 on the box body 41 can also facilitate the heat dissipation of the display panel 42.

[0051] Please continue to see Figure 7 In some embodiments of the present application, a plug-in portion 414 is provided on one of the box body 41 and the panel 30, and a socket is provided on the other of the box body 41 and the panel 30, and the plug-in portion 414 is connected to the socket, so that the installation of the box body 41 is more convenient. Exemplarily, the box body 41 is provided with a plug-in portion 414, and the panel 30 is provided with a socket. When the box body 41 is installed, the plug-in portion 414 is inserted into the socket, so that the box body 41 is fixed on the panel 30, wherein the number of the plug-in portions 414 can be selected according to actual conditions, and the sockets and the plug-in portions 414 are provided in a one-to-one correspondence.

[0052] Alternatively, in some embodiments of the present application, the box body 41 and the panel 30 are fixed by screwing, that is, the box body 41 and the panel 30 are fixed by screws to make the connection between the box body 41 and the panel 30 more stable.

[0053] Alternatively, in some embodiments of the present application, the box body 41 and the panel 30 are fixed by a combination of plug-in and screw connection. For example, a plug-in portion 414 is provided on one side of the box body 41, and a screw connection portion is provided on the other side. The panel 30 is provided with a corresponding plug hole and a screw hole. When installing the box body 41, the plug-in portion 414 of the box body 41 is first inserted into the plug hole, and then the screw connection portion of the box body 41 and the screw hole of the panel 30 are connected by screws, thereby completing the installation and fixing of the box body 41. This not only makes the installation of the box body 41 stable, but also reduces the number of screws used, and reduces the risk of the box body 41 being difficult to disassemble due to rust of the screws.

[0054] See also Figure 8In some embodiments of the present application, the display component 40 also includes a display panel 42 arranged in the box body 41, and the display panel 42 has an electrical connection line 421, and the electrical connection line 421 can be used to power the display panel 42. The main body 10 has a controller, and the controller is used to control the display content on the display panel 42. The electrical connection line 421 can also electrically connect the display panel 42 and the controller of the main body 10.

[0055] A first wire harness trough 415 and a second wire harness trough 416 which are interconnected are provided in the box body 41, and the box body 41 also has a wire outlet 417. The electrical connection wire 421 extends out of the box body 41 through the first wire harness trough 415, the second wire harness trough 416 and the wire outlet 417. The extension direction of the first wire harness trough 415 is perpendicular to the extension direction of the second wire harness trough 416, and the extension direction of the second wire harness trough 416 is perpendicular to the axial direction of the wire outlet 417.

[0056] Among them, the electrical connection line 421 starts from the display panel 42, is wound in multiple different directions, and finally extends out from the wire outlet 417 on the box body 41. Specifically, the electrical connection line 421 makes a vertical turn at the junction of the first wire beam groove 415 and the second wire beam groove 416, and the electrical connection line 421 also makes a vertical turn at the junction of the second wire beam groove 416 and the wire outlet 417, that is, the electrical connection line 421 passes through the first wire beam groove 415, the second wire beam groove 416 and the wire outlet 417 to pass through the box body 41 and turn and wind at least twice. When the electrical connection line 421 is pulled by external force, the groove body of the wire beam groove can disperse the force on the electrical connection line 421, thereby improving the anti-pulling performance of the electrical connection line 421.

[0057] Exemplarily, a cable tie plate is provided in the box body 41, and the cable tie plate is surrounded to form a first cable tie groove 415 and a second cable tie groove 416 that are interconnected. The electrical connection wire 421 is wound in the cable tie plate, and the cable tie plate can share part of the force on the electrical connection wire 421, thereby reducing the loosening or separation between the electrical connection wire 421 and the display panel 42. Among them, the cable outlet 417 can be opened on any side of the box body 41, and the position of the cable outlet 417 can be set according to the specific wiring position, which is not limited in this embodiment.

[0058] See also Figure 7-Figure 8 In some embodiments of the present application, a plurality of boss structures 418 are provided in the box body 41, and the plurality of boss structures 418 enclose and define a receiving space, and the display panel 42 is located in the receiving space, and the receiving space provides an installation position for the display panel 42; and the peripheral side of the display panel 42 is in contact with the boss structure 418, so that the position of the display panel 42 in the receiving space is fixed, thereby reducing the shaking of the display panel 42 in the receiving space.

[0059] In some embodiments, Figure 3and Figure 7 As shown, the box body 41 is recessed downward from the guide surface 411, and the structure recessed into the interior of the box body 41 forms a partial boss structure 418, which together with other boss structures 418 encloses and defines a accommodating space, and the bottom wall of the recessed portion close to the guide surface 411 is also set as an inclined surface. When water droplets flow from the guide surface 411 to the bottom wall of the recessed portion, it is convenient for the water droplets to flow from the bottom wall of the recessed portion to the drain outlet 31.

[0060] Please continue to see Figure 7-Figure 8 In some embodiments of the present application, a snap-in portion 419 is provided in the box body 41, and the snap-in portion 419 is snap-fitted with the display panel 42 to fix the display panel 42 in the box body 41, thereby making the position of the display panel 42 more fixed and preventing the display panel 42 from detaching from the box body 41.

[0061] Among them, the peripheral side of the display panel 42 contacts the boss structure 418 to prevent the display panel 42 from shaking left and right in the accommodating space. At the same time, the clamping portion 419 is clamped with the display panel 42 to prevent the display panel 42 from escaping from the accommodating space, thereby better fixing the display panel 42 in the box body 41.
