[0039] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] The present invention will be described in detail below in conjunction with specific implementation methods.

[0042] In some specific embodiments of the present invention, Figures 1 to 9 As shown, the present solution provides a panel structure of a duct machine, comprising: an air outlet panel 10, provided with a first air outlet area 11, a second air outlet area 12 and a display area 13, the first air outlet area 11 and the display area 13 are arranged in sequence along a first direction, and the first air outlet area 11 and the second air outlet area 12 are respectively located on adjacent sides of the air outlet panel 10; a maintenance panel 20, movably connected to the air outlet panel 10, and arranged corresponding to the display area 13; a display unit 30, detachably connected to the maintenance panel 20.

[0043] It should be noted that by providing a movable maintenance plate 20 on the air outlet panel 10, and arranging the display unit 30 and the maintenance plate 20 to be detachably connected, when disassembly is required during use, the user or maintenance personnel can operate the display unit 30 from the front of the duct machine, and disassemble the maintenance plate 20 and the display unit 30 from the front of the duct machine, ensuring that the maintenance personnel or users can operate from the front, simplifying the disassembly process of the display unit 30, reducing the time and effort spent by maintenance personnel, reducing the difficulty of operation and maintenance costs, and improving the maintenance efficiency of the display unit 30.

[0044] Furthermore, a detachable panel frame is provided at the other end of the air outlet panel 10 connected to the display unit 30, and a snap-on structure connected to the air outlet panel 10 is provided around the panel frame. This arrangement enables a detachable connection between the panel frame and the air outlet panel 10, and when the air outlet panel 10 needs to be disassembled as a whole, the air outlet panel 10 can be removed as a whole from the panel frame.

[0045] In addition, the air outlet panel 10 of the existing duct air conditioner is installed close to the wall, and it is installed on the wall in the horizontal direction. The air outlet direction can only be adjusted by adjusting the angle of the louver. Users located in the air outlet area of ​​the duct air conditioner are easily affected by direct blowing, especially in the cooling mode, which increases the probability of users suffering from air-conditioning disease; therefore, the utility model sets adjacent first air outlet area 11 and second air outlet area 12, and can adjust the outflow of airflow in the first air outlet area 11 and the second air outlet area 12 according to user needs or different usage modes, thereby realizing zoned air outlet and avoiding the phenomenon of direct blowing on users.

[0046] In some possible embodiments of the utility model, it also includes: a shielding unit 14, which is movably arranged in the first air outlet area 11 and includes a first shielding position and a second shielding position; a telescopic mechanism 15, which is arranged on the air outlet panel 10 and is connected to the shielding unit 14, and is used to drive the shielding unit 14 to switch between the first shielding position and the second shielding position; wherein, in the first shielding position, the shielding unit 14 extends out and closes the second air outlet area 12; in the second shielding position, the shielding unit 14 retracts, and the first air outlet area 11 and the second air outlet area 12 are connected.

[0047] Specifically, this embodiment provides an implementation of a shielding unit 14 and a telescopic mechanism 15. The setting of the shielding unit 14 and the telescopic mechanism 15 can meet the normal air outlet of the duct machine on the one hand, and can meet the dust prevention needs when the duct machine is not in working state on the other hand.

[0048] It can be understood that when the first air outlet area 11 is in a non-air outlet state or the duct machine is in a shut-down state, the shielding unit 14 is in a first shielding position under the action of the telescopic mechanism 15, that is, the shielding unit 14 blocks the channel connecting the duct machine and the second air outlet area 12, thereby closing the second air outlet area 12 and preventing dust from entering the machine body through the microporous area, thereby achieving a dust-proof effect; similarly, when the second air outlet area 12 is in an air outlet state, the shielding unit 14 is in a second shielding position under the action of the telescopic mechanism 15, that is, the shielding unit 14 is in a folded, retracted, stored, etc. state, the second air outlet area 12 is turned on, and the airflow can flow out of the duct machine from the second air outlet area 12.

[0049] In a possible embodiment, the telescopic mechanism 15 may adopt an electric telescopic rod, which can drive the shielding unit 14 to telescopically move. When the electric telescopic rod is extended, it shields the bottom of the microporous structure and intercepts dust above the shielding unit 14. When the electric telescopic rod is retracted, the shielding unit 14 moves to one end driven by the electric telescopic rod, so that the bottom of the microporous structure is opened to allow normal air outlet.

[0050] In a possible embodiment, a retractable structure is used to achieve shielding of the air outlet area. It is easy to install and can be electrically controlled. It can be controlled by a controller of the duct machine and operate synchronously with the corresponding air outlet mode.

[0051] Furthermore, the moving direction of the electric telescopic rod is along a direction parallel to the plane where the second air outlet area 12 is located, so that the shielding unit 14 is telescopically folded in the width direction of the first air outlet area 11 .

[0052] In some possible implementations of the present invention, the shielding unit 14 is a foldable film structure.

[0053] Specifically, this embodiment provides an implementation of a shielding unit 14, which uses a film with a certain flexibility to shield the air outlet area. On the one hand, it can ensure its shielding effect, and on the other hand, it will not produce a large resistance to the telescopic mechanism 15, and can easily drive it to fold or unfold.

[0054] In a possible embodiment, a folded film, such as Figure 4 As shown, it can be folded. Of course, according to actual conditions, a foldable film of a specific size can be used so that the foldable film is flat when the electric telescopic rod is extended and is folded when the electric telescopic rod is retracted.

[0055] In some possible embodiments of the utility model, an air guide plate 16 is arranged in the first air outlet area 11, and the air guide plate 16 includes a first air guide position and a second air guide position; wherein, in the first air guide position, a channel for air flow is formed between the air guide plate 16 and the first air outlet area 11; in the second air guide position, the air guide plate 16 closes the first air outlet area 11, and the air flow flows out through the second air outlet area 12.

[0056] Specifically, this embodiment provides an implementation method of the first air outlet area 11, by setting the air guide plate 16 to include a first air guide position and a second air guide position, so that the air guide plate 16 can close and conduct the first air outlet area 11, so that when the air duct machine is in cooling mode, the first air outlet area 11 can be completely closed by the air guide plate 16, so as to prevent the air flow from flowing out of the first air outlet area 11 and causing the problem of direct blowing to the user.

[0057] In some possible implementations of the present invention, a louver air outlet structure or a micro-hole air outlet structure is provided in the second air outlet area 12 .

[0058] Specifically, this embodiment provides an implementation method of a second air outlet area 12. By setting a louver or a microporous structure in the second air outlet area 12, a breeze is achieved at the top of the duct air conditioner, avoiding the problem of direct blowing on the user in the cooling mode, reducing the probability of the user suffering from air-conditioning disease, and ensuring the user's health.

[0059] In some possible implementations of the present invention, at least the area of ​​the maintenance plate 20 corresponding to the display portion 30 is a transparent area.

[0060] Specifically, this embodiment provides an implementation of a maintenance plate 20, which can prevent the user from directly contacting the display surface of the display unit 30, thereby protecting the display surface of the display unit 30. At the same time, the maintenance plate 20 is at least partially set as a transparent area, which also facilitates the user to observe the content displayed on the display unit 30.

[0061] In a possible embodiment, the maintenance plate 20 is made of a material selected from the group consisting of glass, acrylic plastic and resin.

[0062] In some possible embodiments of the utility model, a display shell 40 is provided in the display area 13 of the air outlet panel 10, and a accommodating cavity for accommodating the display part 30 is formed inside the display shell 40, and the display shell 40 protrudes toward the side away from the air outlet panel 10; the maintenance plate 20 is at the opening of the accommodating cavity and is rotatably connected to the display shell 40; wherein, the maintenance plate 20 forms an angle with the plane where the air outlet area is located, and the angle is between 5° and 15°.

[0063] Specifically, this embodiment provides an implementation of a display shell 40, in which the display shell 40 is set on the air outlet panel 10, and the maintenance plate 20 is set at the open part of the display shell 40, and at the same time, the maintenance plate 20 and the plane where the air outlet area is located are set at an angle, so that the user can observe the display part 30 at the bottom, so that the user can directly read the content displayed on the maintenance plate 20 by slightly tilting his head, thereby improving the user experience.

[0064] Furthermore, the maintenance panel 20 and the display shell 40 form an angle, so that the user can know the relevant operating conditions of the duct machine from the front end of the duct machine. Maintenance personnel can also disassemble and repair the display part 30 from the front, which improves the user experience while improving maintenance efficiency and avoiding the problem of overall disassembly.

[0065] It should be noted that the angle is between 5° and 15° because the setting of the angle between the maintenance plate 20 and the plane where the first air outlet area 11 is located can better meet the user's usage habits.

[0066] In some possible embodiments of the present invention, it also includes: a first snap-in unit 21 and a second snap-in unit 41; the first snap-in unit 21 is arranged on the other side of the hinged side of the maintenance plate 20 and the display shell 40; the second snap-in unit 41 is arranged on the other side of the hinged side of the display shell 40 and the maintenance plate 20; wherein the maintenance plate 20 and the display shell 40 are detachably connected by snap-fitting the first snap-in unit 21 and the second snap-in unit 41.

[0067] Specifically, this embodiment provides an implementation of a first snap-in unit 21 and a second snap-in unit 41. Through the arrangement of the first snap-in unit 21 and the second snap-in unit 41, a detachable connection can be achieved between the maintenance plate 20 and the display shell 40, thereby ensuring the connection stability between the maintenance plate 20 and the display shell 40 and facilitating maintenance personnel to disassemble the maintenance plate 20 from the open portion of the display shell 40.

[0068] In some possible embodiments of the utility model, the mating surfaces of the maintenance plate 20 and the display part 30 are provided with a third clamping unit 22 and a positioning column 23, the positioning column 23 is provided with an internal thread, and the third clamping unit 22 and the positioning column 23 are spaced apart along the first direction; the mating surfaces of the display part 30 and the maintenance plate 20 are provided with a fourth clamping unit 31 and a connecting ring 32, and the fourth clamping unit 31 and the connecting ring 32 are arranged at opposite ends of the display part 30 along the first direction; wherein the third clamping unit 22 is clamped with the fourth clamping unit 31, and the connecting ring 32 is connected to the positioning column 23 by connecting screws.

[0069] Specifically, this embodiment provides an implementation of a maintenance plate 20 and a display unit 30. Through the third clamping unit 22 and the positioning column 23 on the maintenance plate 20, and the fourth clamping unit 31 and the connecting ring 32 on the display unit 30, a detachable connection between the maintenance plate 20 and the display unit 30 is achieved, so that after the maintenance personnel remove the maintenance plate 20 from the display shell 40, the display unit 30 can be removed together with the maintenance plate 20, which is convenient for maintenance.
