[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] like Figures 1 to 9 As shown, the first embodiment of the present invention provides a door panel assembly, which includes a door panel 10, a gear 20, a rack 30 and a pusher 40. The gear 20 is meshed with the rack 30, and the rack 30 is connected to the door panel 10 to drive the door panel 10 to move. The door panel 10 is located on the side of the rack 30 away from the gear 20. The pusher 40 is movably arranged on the rack 30, and the pusher 40 has a driving end 41 and a pushing end 42 that are arranged oppositely. The driving end 41 is located between two adjacent teeth of the rack 30 and protrudes from the tooth root of the rack 30, and the pushing end 42 is located between the rack 30 and the door panel 10, so that the gear 20 is meshed with the rack 30. Pusher 40 pushes the door panel 10 to move. The door panel assembly in this embodiment is mainly suitable for an air conditioner indoor unit, and the air conditioner indoor unit can be a cabinet structure.

[0034] With the door panel assembly provided in this embodiment, on the one hand, the gear 20 drives the door panel 10 to move through the rack 30; on the other hand, when the gear 20 is inserted into the position where the driving end 41 is provided, the gear 20 meshes with the rack 30 and pushes the driving end 41 to move, so that the pusher 40 pushes the door panel 10 to move, thereby enabling the door panel 10 to complete two movements. In this way, it is convenient to push the door panel 10 forward when it is in the closed position, thereby reducing the gap between the door panel 10 and the parts on the left and right sides of the air conditioner indoor unit, and preventing external dust or debris from entering the indoor unit housing 90. In addition, the door panel assembly in this embodiment has a simple structure, reliable function, a small number of parts, and is easy to produce and install. At the same time, in this embodiment, it is not necessary to set multiple drive motors, and the motion mechanism has a simple structure. Therefore, the door panel assembly provided in this embodiment can solve the technical problem of the complex structure of the driving mechanism of the door panel assembly in the prior art.

[0035] Specifically, the door panel assembly in this embodiment further includes an elastic reset member 50, one end of which cooperates with the door panel 10, and the other end of which cooperates with the rack 30, and the elastic force direction of the elastic reset member 50 is opposite to the pushing direction of the push member 40, so as to reset the door panel 10 through the elastic reset member 50. Specifically, when the gear 20 is meshed with the rack 30, when it moves to the driving end 41 of the push member 40, the gear 20 will push the door panel 10 to move toward the outer side of the indoor unit housing 90 of the air conditioner indoor unit through the push member 40 to reduce the gap between the door panel 10 and the indoor unit housing 90, at this time, the elastic reset member 50 is compressed. When the gear 20 moves to disengage from the driving end 41 of the push member 40, the door panel 10 will move toward the inner side of the indoor unit housing 90 under the reset action of the reset member, so as to ensure that there is sufficient active gap between the door panel 10 and the indoor unit housing 90, so that the door panel 10 can move smoothly.

[0036] In this embodiment, the elastic reset member 50 is a spring, and the door panel assembly further includes a fastener 60, which passes through the door panel 10 and is connected to the rack 30. The spring is sleeved on the column of the fastener 60, one end of the spring abuts against the door panel 10, and the other end of the spring abuts against the end of the fastener 60 to cooperate with the rack 30. With such a structural arrangement, the door panel 10 can be better reset. Specifically, the fastener 60 can be a screw, which is threadedly connected to the rack 30, and the fastener 60 can be movably inserted into the door panel 10, so that the pusher 40 can push the door panel 10 to move relative to the fastener 60 and the rack 30. Specifically, the door panel assembly in this embodiment further includes a screw positioning block, which is arranged on the rack 30, and the screw positioning block is used to limit the installation depth of the screw, so that the screw can be installed by abutting against the screw positioning block when the screw is tightened.

[0037] Specifically, there are two fasteners 60 in this embodiment, and the two fasteners 60 are arranged at intervals, and the pusher 40 is arranged between the two fasteners 60; the rack 30 has a starting end 31 and a terminal end 32 arranged opposite to each other, and one of the two fasteners 60 is arranged at the terminal end 32. In this way, when the gear 20 is engaged with the starting end 31 of the rack 30, the door panel 10 is in an open position to avoid the air outlet of the indoor unit housing 90, and there is a movable gap between the door panel 10 and the indoor unit housing 90; when the gear 20 is engaged with the terminal end 32 of the rack 30, the door panel 10 is in a closed position to cover the air outlet of the indoor unit housing 90, and the pusher 40 is pushed to push the door panel 10 to move to reduce the movable gap, thereby effectively preventing foreign debris from entering the indoor unit housing 90.

[0038] In this embodiment, the push member 40 includes a push plate 43 and a push strip 44. The push plate 43 is arranged between the rack 30 and the door panel 10. The plate surface of the push plate 43 forms a push end 42 to increase the contact area between the push end 42 and the panel, thereby improving the stability of the push. The push strip 44 is connected to the push plate 43. The push strip 44 is movably arranged on the rack 30 along the extension direction of the push strip 44. The end of the push strip 44 away from the push plate 43 forms a driving end 41. The above structure is simple and reliable. Specifically, the push plate 43 and the push strip 44 are arranged vertically.

[0039] Specifically, a limiting groove 33 is further provided on the side of the rack 30 away from the gear 20 in this embodiment, and the push plate 43 is installed in the limiting groove 33 to facilitate installation and limiting, thereby improving the stability of the structural setting.

[0040] In this embodiment, the push member 40 further includes a mounting bar 45, which is connected to the push plate 43, and is spaced apart from the push bar 44. The extension direction of the mounting bar 45 is the same as the extension direction of the push bar 44, and the mounting bar 45 is movably inserted in the rack 30. With such a structural arrangement, when the push member 40 pushes the driving end 41, both the push bar 44 and the mounting bar 45 can be movably arranged in the rack 30. By adding the mounting bar 45 structure, the stability of the installation can be improved, so that the push member 40 can be stably inserted in the rack 30.

[0041] In order to further improve the stability of the installation, the installation strips 45 in this embodiment are multiple. Specifically, the multiple installation strips 45 in this embodiment are arranged at intervals, and the push strip 44 is arranged between two adjacent installation strips 45. With such a structural arrangement, it is possible to ensure that the push strip 44 can be passed through the rack 30 to smoothly push the door panel 10 to move through the push plate 43, and the stability of the structural arrangement can also be ensured.

[0042] Specifically, in this embodiment, the rack 30 is an arc structure, and a mounting through hole 34 extending radially along the rack 30 is provided in the rack 30, and at least a portion of the pusher 40 is movably inserted in the mounting through hole 34, so as to push the door panel 10 to move through the pusher 40. The push bar 44 in this embodiment is movably inserted in the mounting through hole 34, so that the push bar 44 pushes the door panel 10 to move through the push plate 43.

[0043] In this embodiment, the door panel assembly also includes a base 70, on which a guide groove 71 is provided. The groove shape of the guide groove 71 is adapted to the shape of the rack 30, and the guide groove 71 extends along the movement direction of the rack 30 so that the rack 30 can be movably arranged in the guide groove 71 to improve the movement smoothness of the rack 30.

[0044] Specifically, the door panel assembly in this embodiment further includes a rolling member 80, which is mounted on the rack 30, and the rolling end of the rolling member 80 is protruding from the bottom of the rack 30, so that the rolling member 80 rolls in the guide groove 71. The above structure can further improve the smoothness of the movement of the rack 30, reduce the contact area between the rack 30 and the base 70, so that the rack 30 can move smoothly in the guide groove 71. Specifically, there can be multiple rolling members 80, and the multiple rolling members 80 are spaced on the rack 30 along the extension direction of the rack 30 to better improve the smoothness of the movement.

[0045] In this embodiment, the guide groove 71 has a first end and a second end that are arranged opposite to each other, the first end is provided with a first limit plate 72, and the second end is provided with a second limit plate 73, so that the rack 30 is abutted by the first limit plate 72 and the second limit plate 73. With such a structural arrangement, the first limit plate 72 and the second limit plate 73 can effectively limit the range of motion of the rack 30, and prevent the rack 30 from moving to a position where it is separated from the gear 20, so as to ensure that the rack 30 can reciprocate.

[0046] The door panel assembly in this embodiment includes an upper moving component 120 and a lower moving component 140. The upper moving component 120 and the lower moving component 140 have the same structure and are respectively arranged at two ends of the door panel 10. The upper moving component 120 and the lower moving component 140 both include a gear 20, a rack 30, a pusher 40, a base 70 and a top cover 100. With such a structural arrangement, during the movement of the door panel assembly, by arranging the upper moving component 120 at the top end of the door panel 10 and arranging the lower moving component 140 at the bottom end of the door panel 10, the door panel 10 is simultaneously driven to rotate and push outward under the joint action of the upper moving component 120 and the lower moving component 140, so that the stability of the movement of the door panel 10 can be improved, so that the door panel 10 can be smoothly moved to the open position or the closed position, and the smoothness of the movement of the door panel 10 can be improved. This avoids the situation where only the upper moving component 120 or the lower moving component 140 drives the door panel 10 to move, causing the door panel 10 to move poorly or even get stuck due to the long length of the door panel 10 .

[0047] The main structure of the door panel assembly in this embodiment includes a door panel 10, an upper moving component 120 and a lower moving component 140. The upper and lower ends of the door panel 10 have stepped mounting structures, which are used to be mounted on the moving component. The mounting part is hidden on the upper panel 110 and the lower panel 130. The mounting structure can facilitate the positioning and mounting of the upper moving component 120 and the lower moving component 140, and also facilitates achieving a better sealing effect and a neater and more beautiful appearance.

[0048] The horizontal cross-sectional view of the indoor unit of the air conditioner of the present invention is shown in FIG. Figure 7 , which shows the movement of the door panel 10. The upper moving part 120 and the lower moving part 140 drive the door panel 10 to move left and right. The screenshot position is when the door panel 10 is in a closed state. There is a gap between the left and right sides of the door panel 10, which has a great impact on insect and dust prevention. When the door panel 10 is opened, it rotates to the right and turns into the interior of the indoor unit housing 90. At this time, the wind sweeping structure starts to sweep the air, and the air conditioner starts to work. Sufficient gaps must be ensured during this movement process, otherwise it may cause movement jamming, abnormal noise, jamming and other problems.

[0049] The implementation form of the present invention is shown in Figure 1, its electrical drive gear 20, gear 20 drives rack 30 to move, the state shown in the figure is the state that the door panel 10 is about to be pushed out (or the state of starting to close). In this state, the door panel 10 is in a closed state, the rack 30 moves from right to left, and when the rack 30 meshes with the next tooth, it supports the pusher 40, the spring for installing the door panel 10 is compressed, and the door panel 10 moves forward, making the sealing effect better, that is, the gap with the indoor unit housing 90 is reduced. When the door panel 10 is in an open state, the gear 20 staggers the push rod structure, and the spring has pressure to return the door panel 10, that is, the door panel 10 is retracted inward to ensure the movement gap during the closing process.

[0050] In the implementation of the present invention, the door panel assembly also includes a fixed cover and a base 70, which includes parts such as a gear 20 and a rack 30. The rack 30 moves on the slide rail (i.e., the guide groove 71) of the moving component mounting seat through a pulley (or a roller). Figure 1 The screws and springs of the door panel 10 fix the door panel 10, and the pusher 40 is pushed into the mounting hole of the rack 30. The installation method is as follows. Figure 4 The rack 30 of the present invention is characterized by a mounting through hole 34 on a rear side section, a positioning block hole (for mounting a screw positioning member), a connecting through hole, etc. The assembly is simple and convenient with high efficiency.

[0051] The door panel assembly provided by the embodiment of the present invention has a structure with a small number of parts and a simple assembly structure. Compared with the conventional non-pushing moving parts, the door panel 10 can be closed more tightly when closed, with better insect and dustproof effects and better appearance effects. When opened, the movement gap can be guaranteed, and the movement is not easy to get stuck, jammed or worn. Compared with the conventional moving parts with a separate motor push-out structure, it saves almost half of the parts, 2 motors (one each at the top and bottom) and corresponding parts, reduces noise, reduces costs, saves nearly 1 / 3 of the space, and has higher assembly efficiency.

[0052] Embodiment 2 of the present invention provides an air conditioner indoor unit, the air conditioner indoor unit includes an indoor unit housing 90 and a door panel assembly, the door panel assembly is arranged on the indoor unit housing 90, and the door panel assembly is the door panel assembly provided above. With the air conditioner indoor unit provided by the above embodiment, since the door panel assembly has two different movements at the same time (the door panel 10 moves to the closed position and the door panel 10 is pushed outward), the gap between the door panel 10 and the indoor unit housing 90 can be reduced, thereby preventing foreign debris from entering the indoor unit housing 90.

[0053] Specifically, the door panel assembly in this embodiment is the door panel assembly provided above, and the indoor unit housing 90 has an air outlet. When the starting end 31 of the rack 30 of the door panel assembly is meshed with the gear 20 of the door panel assembly, the door panel 10 of the door panel assembly avoids the air outlet setting, and there is a movable gap between the door panel 10 and the indoor unit housing 90, so that the door panel 10 can move smoothly. When the terminal end 32 of the rack 30 of the door panel assembly is meshed with the gear 20, the door panel 10 of the door panel assembly covers the air outlet setting, and the pusher 40 of the door panel assembly pushes the door panel 10 to move to reduce the movable gap, so as to effectively prevent foreign debris from entering the indoor unit housing 90.

[0054] The indoor unit housing 90 in this embodiment includes an upper panel 110 and a lower panel 130, which are respectively arranged on the upper and lower sides of the door panel 10. The upper panel 110 is located at the top of the door panel 10, and the lower panel 130 is located at the bottom of the door panel 10.

[0055] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: Due to the use of the door panel assembly of the present invention, it is not necessary to add an additional motor to push the door panel to the outside of the indoor shell, so as to achieve better sealing of the door panel; due to the use of the moving component form of the present invention, when the door panel is opened, it can be guaranteed to have sufficient movement clearance, so that it can move smoothly without jamming and with low noise. Due to the use of the rack and pusher structure of the present invention, its structure is simple, no separate forward pushing mechanism is required, its assembly efficiency is higher, cost is lower, and reliability is good. Due to the use of the large door panel and moving component form of the present invention, the insect and dustproof effect of the whole machine is better, the noise and abnormal sound of the moving component is smaller, and a better appearance effect can also be achieved. Due to the use of the large door panel and moving component form of the present invention, its assembly volume is smaller, which can save space.
