[0002] At present, in order to facilitate maintenance, an inspection window is preset on the back panel of the indoor unit of the vertical air conditioner, and a detachable inspection panel is set on the inspection window. In this way, the inspection window is covered with the inspection panel under normal use; when maintenance is required, the inspection panel is removed to inspect and replace the internal components of the indoor unit. The existing inspection panel forms a snap structure and a connecting hole on one side, and a connecting ear and a positioning hole thereon on the other side, so that when the inspection panel is connected to the inspection window, the inspection panel is connected to the back panel through the plug connection of the positioning hole and the positioning column, the snap connection of the snap structure, and the fastening connection of the fastening screw on the connecting hole; similarly, when it is necessary to open the inspection window from the back panel, the above-mentioned connection structures need to be opened one by one. However, the above-mentioned inspection panel has many connection positions on the back panel, which results in many installation points during the manufacturing process. The installation process is time-consuming and labor-intensive, which in turn leads to reduced production efficiency and increased production costs of the indoor unit.

[0045] Figure 1 is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the utility model provides an indoor unit of an air conditioner, comprising a housing 100 and an access panel 600, wherein the housing 100 forms an access window 200, and a track portion 300 located at least on one side of the access window 200 in the horizontal direction. The track portion 300 extends vertically. The access panel 600 is located at the inner side of the access window 200, and the access panel 600 forms a connecting portion 610 slidably connected to the track portion 300, and is configured to move vertically along the track portion 300, so that the access panel 600 has a first position of closing the access window 200 and a second position of opening the access window 200 in the vertical movement stroke.

[0046] In this embodiment, the user or maintenance personnel can inspect and replace the internal components of the indoor unit through the inspection window 200. When the inspection window 200 is not needed, the inspection window 200 is covered with the inspection plate 600 to prevent damage to the internal components of the indoor unit. The inspection plate 600 is located inside the inspection window 200 to prevent the inspection plate 600 from occupying excess space. The track portion 300 is used to limit the position and movement direction of the inspection plate 600 and is slidably connected to the connecting portion 610 of the inspection plate 600. When it is not necessary to use the inspection, the inspection plate 600 is located inside the inspection window 200 and completely covers the inspection window 200, and the inspection plate 600 is in the first position. When the user or maintenance personnel needs to inspect and replace the internal components of the indoor unit through the inspection window 200, the inspection plate 600 is pushed upward, and the inspection plate 600 moves upward along the track portion 300 for a distance to open the inspection window 200, and the inspection plate 600 is in the second position. Since there is no need to install snap-on structures or fixing parts such as fastening screws to fix the inspection panel 600, the technical solution of the present application solves the problem of inconvenient installation of the inspection panel 600 on the casing 100, and the operation of opening or covering the inspection window 200 is convenient, thereby improving the user experience.

[0047] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the track portion 300 includes two vertical slideways 310, and the two vertical slideways 310 are respectively located at the two lateral sides of the inspection window 200. The inspection panel 600 also includes a body 620, and the connecting portion 610 is fixedly connected to the two lateral ends of the body 620. Each connecting portion 610 is inserted and slidably connected to a vertical slideway 310.

[0048] In this embodiment, the access panel 600 is located between two vertical slides 310 arranged vertically, and is limited at or above the access window 200 by the two vertical slides 310. The body 620 is connected to the two vertical slides 310 through two connecting parts 610 on both sides, and changes its position by sliding to open or cover the access window 200. The design of the two vertical slides 310 makes the sliding of the access panel 600 more stable, and prevents the access panel 600 from falling off.

[0049] In some embodiments of the present invention, Figure 3 As shown, the horizontal cross-sections of the two vertical slides 310 are L-shaped, and each vertical slide 310 includes a first plate 311 and a second plate 312. The first plate 311 is located inside the inspection window 200, and on the horizontal projection plane, the extension lines of the two first plates 311 intersect at the inside of the inspection window 200. The two second plates 312 respectively form the edges of the two lateral sides of the inspection window 200. Each first plate 311 is at one end of the corresponding second plate 312 away from the inspection window 200.

[0050] In this embodiment, the extension line of the first plate 311 forms an angle on the inner side of the inspection window 200, and the inspection plate 600 is clamped between the two first plates 311 and the two second plates 312, and does not require fixing parts such as fixing screws, and has a simple structure, which reduces the manufacturing cost. Moreover, the inspection window 200 can be opened and closed by pushing and pulling the inspection plate 600 up and down, which is simple to operate and improves the user experience.

[0051] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, in the transverse direction, the inspection window 200 includes a middle section 220 and arc sections 210 at both ends of the middle section 220. The opening direction of the arc section 210 faces the inside of the inspection window 200. The second plate 312 is arranged along the extension direction of the arc section 210.

[0052] In this embodiment, since the second plate 312 is disposed along the extending direction of the arc segment 210 , that is, the second plate 312 is an inner arc plate with its opening direction facing the inspection window 200 .

[0053] In some other embodiments of the present invention, the second plate 312 is a flat plate, and the second plate 312 is tangentially connected to the arc segment 210 .

[0054] Preferably, the first plate 311 and the second plate 312 are arranged vertically, so that there is an angle between the extension lines of the two first plates 311, so that the inspection plate 600 is clamped between the two first plates 311 and the two second plates 312. The first plate 311 and the second plate 312 are arranged vertically, so that there is no too small angle at the vertical slide 310, which is convenient for demoulding during the production process, reduces the difficulty of production, and thus reduces the cost.

[0055] In other embodiments of the present invention, a telescopic slide rail is provided on the vertical slideway 310, and the inspection panel 600 is connected to the telescopic slide rail.

[0056] In this embodiment, the inspection panel 600 is connected to the inspection window 200 via a telescopic slide rail, so that the resistance when the inspection panel 600 moves is small, the opening and closing of the inspection window 200 is smoother, and the user experience is improved.

[0057] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the body 620 may be in the shape of a flat plate. The surface of the second plate 312 facing the inner side of the inspection window 200 is matched with the surface of the connecting portion 610 facing the outer side of the inspection window 200 and is in contact connection.

[0058] In this embodiment, the arc segment 210 matches the connecting portion 610 in shape, so that the gap between the arc segment 210 and the connecting portion 610 is smaller, making the structure of the air conditioner more compact and improving space utilization.

[0059] In some embodiments of the present invention, Figure 2 As shown, the housing 100 further forms a limiting column 400, which is arranged in the vertical direction. The limiting column 400 includes a first limiting section 410, and the bottom end of the first limiting section 410 is directly or indirectly fixedly connected to the bottom edge of the inspection window 200. A limiting surface is formed on one side of the first limiting section 410 facing the outside of the inspection window 200. At least when the inspection panel 600 is in the first position, the limiting surface contacts the side of the inspection panel 600 facing the inside of the inspection window 200.

[0060] In this embodiment, the limiting surface serves to limit the inspection panel 600, preventing the inspection panel 600 from falling off from the inside of the inspection window 200, thereby making the installation of the inspection panel 600 more stable and improving the quality of the air conditioner.

[0061] In some embodiments of the present invention, Figure 4 As shown, the limiting column 400 further includes a second limiting section 420, which is located at the top of the first limiting section 410 and protrudes outward from the inspection window 200. At least when the inspection plate 600 is in the second position, the second limiting section 420 abuts against the bottom of the inspection plate 600.

[0062] In this embodiment, when the inspection window 200 is opened, the inspection panel 600 moves upward to the second position, and the bottom of the inspection panel 600 contacts and connects to the top of the second limiting section 420, and the position of the inspection panel 600 is fixed. The second limiting section 420 is provided so that the user or maintenance personnel no longer need to use hands or other objects to support the inspection panel 600 when inspecting and replacing the components inside the indoor unit through the inspection window 200, making the inspection operation more convenient. In addition, the second limiting section 420 has a simple structure and is easy to manufacture.

[0063] Further, in some embodiments of the present invention, Figure 2 As shown, there are two limit posts 400 , which are arranged at intervals in the transverse direction, so that the access panel 600 is more stable when in the second position, and the access panel 600 is prevented from falling off toward the inside of the access window 200 .

[0064] In some embodiments of the present invention, Figure 2 and Figure 4As shown, the housing 100 further includes a stopper 500, which is fixedly connected to the bottom edge of the inspection window 200 and is located inside the inspection window 200. The vertical cross section of the stopper 500 is L-shaped, and the stopper 500 includes a bottom plate 510 extending from the bottom edge of the inspection window 200 to the inside of the inspection window 200, and a side plate 520 extending upward from the edge of the bottom plate 510 facing the inside of the inspection window 200. When the inspection plate 600 is in the first position, the bottom end of the inspection plate 600 contacts the bottom plate 510, and the side surface of the inspection plate 600 facing the inside of the inspection window 200 contacts the side plate 520.

[0065] In this embodiment, the limiting platform 500 limits the access panel 600. Specifically, the bottom plate 510 supports the access panel 600 upward when the access panel 600 is in the first position. Also, the side plate 520 prevents the access panel 600 from falling to the inside of the access window 200 when the access panel 600 is in the first position. This allows the access panel 600 to be more stably fixed to the access window 200.

[0066] Furthermore, in some embodiments of the present invention, the bottom end of the vertical slide 310 extends to the bottom plate 510, and the surface of the first plate 311 facing the inner side of the inspection window 200 is flush with the surface of the side plate 520 facing the inner side of the inspection window 200, so that the structure of the vertical slide 310 and the limit platform 500 is more solid, thereby increasing the stability of the inspection plate 600.

[0067] In some embodiments of the present invention, the surface of the limiting column 400 facing the outer side of the inspection window 200 is flush with the surface of the side plate 520 facing the outer side of the inspection window 200 .

[0068] In this embodiment, the surface of the limit post 400 facing the outside of the inspection window 200 is flush with the surface of the side plate 520 facing the outside of the inspection window 200 to reduce interference with the inspection plate 600. In addition, the flush design can simplify the difficulty of demoulding during production and reduce production costs.

[0069] Preferably, in some embodiments of the present invention, in the vertical direction, the top of the limiting column 400 is lower than the upper edge of the inspection window 200. Also, in the vertical direction, the top of the limiting column 400 is higher than the middle of the inspection window 200.

[0070] In this embodiment, the top of the limiting post 400 is higher than the middle of the access window 200, so that when the access panel 600 is in the second position, a window size sufficient for the user or maintenance personnel to operate is reserved. The top of the limiting post 400 is lower than the upper edge of the access window 200, so that when the user pushes the access panel 600 upward or downward, there is always a position on the access panel 600 at the access window 200 where force can be applied, which is convenient for user operation and improves the user experience.

[0071] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the access panel 600 also forms a handle 700, which is a groove recessed toward the inner side of the access window 200. The handle 700 and the access panel 600 are an integrally formed structure, so that the fixation of the handle 700 is more secure and the service life of the handle 700 is increased. Moreover, the handle 700 is recessed toward the inside of the housing 100, so that the handle 700 will not interfere when the access panel 600 moves.

[0072] In other embodiments of the present invention, the handle 700 and the inspection plate 600 are separate structures to reduce manufacturing difficulty and manufacturing cost.

[0073] In some embodiments of the present invention, the width of the access panel 600 is greater than the width of the access window 200 to improve the stability of the access panel 600 .

[0074] In some embodiments of the present invention, the height of the access panel 600 is greater than the height of the access window 200 to improve the stability of the access panel 600 .

[0075] In some embodiments of the present invention, the access plate 600 is also provided with through holes allowing the air conditioning heat exchange pipeline to pass through.

[0076] The embodiment of the utility model also provides an air conditioner, comprising an air conditioner outdoor unit and an air conditioner indoor unit as in any of the above embodiments. The air conditioner outdoor unit is configured to perform heat exchange in an outdoor environment. The air conditioner indoor unit is connected to the outdoor unit to be configured to perform heat exchange in an indoor environment.

[0077] In this embodiment, the outdoor unit and the indoor unit cooperate with each other to achieve heat exchange of the air conditioner. The user or maintenance personnel can inspect and replace the components inside the indoor unit through the maintenance window 200 on the indoor unit. When the maintenance window 200 is not needed, the maintenance window 200 is covered with an inspection plate 600 to prevent damage to the components inside the indoor unit. The maintenance plate 600 is located on the inner side of the maintenance window 200 to prevent the maintenance plate 600 from occupying excess space. The track portion 300 is used to limit the moving direction of the maintenance plate 600 and is slidably connected to the connecting portion 610 of the maintenance plate 600. When maintenance is not needed, the maintenance plate 600 is located on the inner side of the maintenance window 200 and completely covers the maintenance window 200. At this time, the maintenance plate 600 is in the first position. When the user or maintenance personnel needs to inspect and replace the internal components of the indoor unit through the inspection window 200, the inspection panel 600 is pushed upward, and the inspection panel 600 moves upward along the track portion 300 for a distance to open the inspection window 200. At this time, the inspection panel 600 is in the second position. There is no need to install fixing parts such as a snap-fit ​​structure or fastening screws to fix the inspection panel 600, which solves the problem of inconvenience in installing the inspection panel 600 on the housing 100, and the operation of opening or covering the inspection window 200 is convenient, which improves the user experience.

[0078] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
