[0028] The present invention provides a partition structure, please refer to Figures 1 to 3 , used to be arranged in the air duct 50 of the air conditioner indoor unit, the partition structure includes: a partition body 30, used to be connected to the shell of the air conditioner indoor unit; at least one air duct partition plate 40, arranged on the partition body 30; along the first extension direction of the air duct 50, at least one air duct partition plate 40 divides the air duct 50 into at least two air duct sections, so that the airflow entering the air duct 50 flows out after passing through the at least two air duct sections respectively.

[0029] The partition structure of the present invention is used to be arranged in the air duct 50 of the indoor unit of the air conditioner. The partition structure includes a partition body 30 and a duct partition plate 40 arranged on the partition body 30. The duct partition plate 40 divides the air duct 50 into at least two duct sections. The airflow entering the air duct 50 flows through at least two duct sections and then flows out. The duct partition plate 40 divides the airflow to make the internal wind field distribution more uniform, thereby obtaining a better air flow effect, preventing the wind direction from being dispersed, and evenly discharging air to make people comfortable; and, in the case where the air duct is narrow and long and the air inlet and outlet paths are long, the airflow backflow can be prevented to avoid surging.

[0030] Specifically, the air duct 50 has a first extension direction and a second extension direction, and the first extension direction is perpendicular to the second extension direction; Figure 1 As shown, the x direction indicated by the arrow is the first extension direction; Figure 2 As shown, the y direction indicated by the arrow is the second extension direction; wherein the second extension direction is also the air outlet direction of the air duct 50.

[0031] The narrow and long air duct means that the air duct is longer in the second extending direction.

[0032] Specifically, the air-conditioning indoor unit is a wall-mounted air-conditioning indoor unit, and the first extension direction is the length direction of the wall-mounted air-conditioning indoor unit.

[0033] In this embodiment, the housing of the air conditioner indoor unit includes a panel 10, and a partition structure is used to be arranged between the panel 10 and the evaporator 20 of the air conditioner indoor unit to separate the evaporator 20 from the panel 10; a partition body 30 is used to be connected to the panel 10, and the partition body 30 has a first end face and a second end face that are arranged opposite to each other, the first end face is in contact with the inner side surface of the panel 10, and the second end face is arranged opposite to the evaporator 20; and an air duct partition plate 40 is arranged on the second end face. The partition structure can separate the panel 10 from the evaporator 20 and prevent it from directly contacting the air conditioning wind by connecting the partition body 30 to the panel 10 and making the first end face of the partition body 30 in contact with the inner side surface of the panel 10. The partition body 30 plays the role of isolating temperature and heat preservation, so that the temperature of the panel 10 is relatively constant, and condensation is prevented from occurring on the panel, thereby solving the problem of condensation occurring on the panel due to temperature changes of the evaporator during operation.

[0034] Specifically, the partition structure is arranged in the air duct, and the first end face cooperates with the inner surface shape of the panel 10 to ensure that the two are securely fitted. When the evaporator is cooling or heating, the temperature fluctuates, but due to the heat preservation effect of the partition body, the panel will not produce condensation water due to sudden temperature changes, affecting the appearance.

[0035] Specifically, the partition body 30 further has a first surface, and the first surface is adapted to the surface of the evaporator 20 . The first surface is in contact with the surface of the evaporator 20 to ensure the sealing of the air duct.

[0036] In this embodiment, the partition structure further includes at least one air duct partition plate 40, which is disposed on the second end surface of the partition body 30. The air duct partition plate 40 is used to be disposed in the air duct 50 of the indoor unit of the air conditioner to divide the air duct 50 into at least two air duct sections. The air duct partition plate 40 divides the airflow to make the internal wind field distribution more uniform, thereby obtaining a better air flow effect, preventing the wind direction from being dispersed, and evenly discharging the air to make people comfortable.

[0037] Specifically, the air duct of the indoor unit of a wall-mounted air conditioner is long and narrow along its extension direction, which can easily lead to air flow backflow and surging problems. The separation structure of the present application divides the air duct into multiple shorter air duct segments along its extension direction, thereby alleviating the problem of air flow backflow and surging caused by the long and narrow air duct, and greatly reducing the more obvious "booming" noise generated by the inner cavity; at the same time, it solves the problem of scattered wind direction caused by the long air inlet and outlet paths.

[0038] like Figure 2 As shown, there are multiple duct partition plates 40, and the multiple duct partition plates 40 are spaced apart along the first extension direction so that the airflow flows between two adjacent duct partition plates 40. One end of each duct segment is connected to the air inlet of the air conditioner indoor unit, and the other end of each duct segment is connected to the air outlet of the air conditioner indoor unit.

[0039] like Figure 2 As shown, the air duct dividing plate 40 divides the originally long and wide air duct into four independent air duct sections, straightening out the wind that is originally scattered in direction, uneven in volume, and surging due to long-distance transportation in the air duct, so that each section can achieve a good air supply effect, avoiding the obvious "booming" noise caused by the wind rushing around in the narrow and long air duct, and the air output is uniform, making people feel comfortable.

[0040] Preferably, the distances between two adjacent air duct dividing plates 40 are the same.

[0041] like Figure 2 As shown, the first side surface 41 of the air duct partition plate 40 is adapted to the surface of the evaporator 20, and the first side surface 41 is in contact with the surface of the evaporator 20. The evaporator 20 has a second surface, which is arranged opposite to the partition structure, and the second surface and the first side surface 41 are both inclined, and the inclination angle of the first side surface 41 is the same as the inclination angle of the second surface, that is, the two are parallel, so that the two are in contact.

[0042] like Figure 2As shown, in one embodiment, the cross section of the air duct 50 perpendicular to the first extension direction is triangular, the shape of the air duct dividing plate 40 is adapted to the shape of the air duct 50, and the projection surface of the air duct dividing plate 40 perpendicular to the first extension direction is triangular.

[0043] In another embodiment, the cross section of the air duct 50 perpendicular to the first extension direction is trapezoidal, and the projection surface of the air duct dividing plate 40 perpendicular to the first extension direction is trapezoidal.

[0044] Optionally, the partition body 30 is made of expanded polypropylene material, wherein the expanded polypropylene material is EPP (Expanded polypropylene).

[0045] Optionally, the air duct partition plate 40 is made of foamed polypropylene material; or, the air duct partition plate 40 includes a support member and a partition layer wrapped on the support member, and the partition layer is made of foamed polypropylene material.

[0046] In this embodiment, a first noise reduction layer is provided on the second end surface; and / or a second noise reduction layer is provided on the surface of the air duct partition plate 40; wherein the first noise reduction layer and the second noise reduction layer are both made of sound-absorbing material or sound-reducing material. The air duct is narrow and long, and the air inlet and outlet paths are long, which can easily lead to airflow reflux and surge problems. The inner cavity further amplifies the noise, seriously affecting the customer experience. Pasting sound-absorbing material or sound-reducing material on the air duct partition plate 40 and the second end surface, such as porous and loose materials such as pearl cotton, can greatly suppress noise and play a role in noise reduction.

[0047] like Figure 3 As shown, a plurality of first grooves arranged at intervals are arranged on the second end surface; and / or a plurality of second grooves 42 arranged at intervals are arranged on the surface of the air duct partition plate 40. In this way, by arranging the uneven first and second grooves 42 on the second end surface and the surface of the air duct partition plate 40, the sound absorption area of ​​the first noise reduction layer and the second noise reduction layer is increased. Of course, the second end surface and the surface of the air duct partition plate 40 can also be arranged to be streamlined to reduce wind resistance and make the wind flow smoother, thereby greatly reducing noise decibels.

[0048] Specifically, the plurality of first grooves include a plurality of grooves extending along a first preset direction and a plurality of grooves extending along a second preset direction; wherein the first preset direction is perpendicular to the second preset direction.

[0049] Specifically, Figure 3 As shown, the plurality of second grooves 42 also include a plurality of grooves extending along a first preset direction and a plurality of grooves extending along a second preset direction; wherein the first preset direction is perpendicular to the second preset direction.

[0050] In another embodiment, by setting the second end surface and the surface of the air duct dividing plate 40 to be uneven, the effect of sound absorption and noise reduction is achieved.

[0051] In this embodiment, a buckle or a slot is provided on the partition body 30, and the buckle or the slot is used to be snapped with the slot or buckle of the panel 10; and / or, a fastening hole is provided on the partition body 30, and the partition body 30 is connected to the panel 10 via a fastener passed through the fastening hole.

[0052] The present invention also provides an air conditioner indoor unit, comprising a panel 10, an evaporator 20 and an air duct 50, wherein the air conditioner indoor unit further comprises a partition structure 1, the partition structure 1 is arranged between the panel 10 and the evaporator 20, and the partition structure is the partition structure in the above embodiment.

[0053] In specific implementation, the partition body 30 and the air duct partition plate 40 of the present application are not limited to foamed polypropylene materials. Any material with heat preservation function can be used as a partition structure, and any material with noise reduction material or noise reduction function can be pasted on the surface is also suitable for the application.

[0054] The structure and assembly position of the partition structure of the present application are not limited to the position in the air duct and the designed structure described in the present application, and the structure and position can be appropriately changed according to actual conditions.

[0055] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0056] The partition structure of the present invention is used to be arranged in the air duct 50 of the indoor unit of the air conditioner. The partition structure includes a partition body 30 and a duct partition plate 40 arranged on the partition body 30. The duct partition plate 40 divides the air duct 50 into at least two duct sections. The airflow entering the air duct 50 flows through at least two duct sections and then flows out. The duct partition plate 40 divides the airflow to make the internal wind field distribution more uniform, thereby obtaining a better air flow effect, preventing the wind direction from being dispersed, and evenly discharging air to make people comfortable; and, in the case where the air duct is narrow and long and the air inlet and outlet paths are long, the airflow backflow can be prevented to avoid surging.
