[0054] Figure 1 is a schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 2 yes Figure 1 The cross-sectional schematic diagram of the air conditioner indoor unit 20 is shown at the AA position.

[0055] refer to Figure 1 and Figure 2 As shown, this embodiment provides an air conditioner indoor unit 20 with a fresh air module 30 , and the air conditioner indoor unit 20 includes an air duct component 22 , a fresh air module 30 and a filter module 40 .

[0056] The air duct component 22 defines an air supply duct and an air outlet at the front end of the air supply duct. The fresh air module 30 is arranged on the rear side of the air duct component 22 and connected to the air supply duct, and is used to transport fresh air from the outside into the air supply duct. A mounting opening 22A that passes through the front and back is provided on the rear wall of the air supply duct, and the fresh air module 30 defines a fresh air filter chamber 32A having an opening facing the mounting opening. The filter module 40 has a filter portion 42 inserted into the fresh air filter chamber 32A, and an operating portion 44 for closing the mounting opening 22A; the filter module 40 is used to filter the fresh air flowing through the filter portion 42 in the fresh air filter chamber 32A; the filter module 40 is configured to be installed or removed from the air outlet.

[0057] Unfiltered outdoor fresh air may contain impurities such as dust. In order to prevent these impurities from polluting the indoor environment while providing fresh air, the air conditioner indoor unit 20 of this embodiment is also provided with a filter module 40. The filter part 42 of the filter module 40 is inserted into the fresh air filter chamber 32A of the fresh air module 30, and the fresh air flowing through the filter part 42 in the fresh air filter chamber 32A is filtered.

[0058] The filter part 42 of the filter module 40 may be provided with dust filter or activated carbon or other items capable of absorbing and filtering dust. In order to facilitate the user to disassemble and clean the filter module 40, the present embodiment starts a front-to-back through-mounting opening 22A on the rear wall of the air supply duct, and makes the opening of the fresh air filter chamber 32A face the mounting opening 22A, so that the user can install or remove the filter module 40 from the air outlet. The user only needs to extend his hand or operating tool from the air inlet of the air conditioner indoor unit 20 into the air supply duct to remove the filter module 40 inserted into the mounting opening 22A.

[0059] The air conditioner indoor unit 20 of this embodiment sets the fresh air module 30 on the rear side of the air duct member 22, so as not to affect the length of the air conditioner indoor unit 20. The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20 set in a cabinet or other container and is set in various home scenes, such as a wardrobe in a bedroom, a cabinet in a kitchen, a bookcase in a study, etc. This embodiment does not limit the specific use of the cabinet. The cabinet usually has a greater depth than the front and rear width of the air conditioner indoor unit 20, so when the air conditioner indoor unit 20 of this embodiment is set in the cabinet, the space at the rear of the cabinet can be utilized.

[0060] However, the air conditioner indoor unit 20 of the present embodiment may also be a wall-mounted air conditioner indoor unit 20. By adjusting the shapes of the fresh air module 30 and the filter module 40, the increase in the front and rear width of the air conditioner indoor unit 20 caused by the provision of the fresh air module 30 can be reduced, so that the air conditioner indoor unit 20 can be used as a wall-mounted air conditioner indoor unit 20.

[0061] refer to Figure 1 As shown, the air outlet of the air conditioner indoor unit 20 of this embodiment can be oriented forward and opened on the front side of the air conditioner indoor unit 20, and the air inlet can also be opened on the front side of the air conditioner indoor unit 20. Since cabinets generally have a forward opening and the upper side is blocked, when the air conditioner indoor unit 20 of this embodiment is set in a cabinet or other container, air can be taken in and out from the front side with an opening at the same time, so it is more suitable for embedded installation scenarios.

[0062] Figure 3 yes Figure 1 The cross-sectional schematic diagram of the air conditioner indoor unit 20 is shown at the BB position.

[0063] refer to Figure 3 As shown, in some optional embodiments, the fresh air module 30 includes: a module body 32 , a fresh air pipe 36 and a fresh air duct 34 .

[0064] The module body 32 defines a fresh air filter chamber 32A and a fan chamber 32B connected to the fresh air filter chamber 32A. The fresh air duct 36 is connected to the fresh air filter chamber 32A, and is used to transport fresh air from the outside to the fresh air filter chamber 32A. The fresh air duct 34 connects the fan chamber 32B and the air supply duct, and is used to transport fresh air from the module body 32 to the air supply duct. A fresh air fan is provided in the fan chamber 32B, and is used to cause fresh air to flow from the outside through the fresh air module 30 into the air supply duct.

[0065] The fresh air module 30 of this embodiment includes three parts: a module body 32, a fresh air pipe 36, and a fresh air duct 34. The module body 32 defines a fresh air filter chamber 32A and a fan chamber 32B. A fresh air fan is arranged in the fan chamber 32B. Fresh air enters the fresh air filter chamber 32A of the module body 32 from the fresh air pipe 36, flows through the filter module 40 in the fresh air filter chamber 32A, enters the fan chamber 32B, and then enters the air supply duct through the fresh air duct 34.

[0066] Figure 4 yes Figure 1 A schematic diagram of the air duct component 22 of the indoor unit 20 of the air conditioner is shown; Figure 5 yes Figure 4 A schematic diagram of a fresh air module 30 of an air conditioner indoor unit 20 is shown.

[0067] In some optional embodiments, a uniform wind slot 22B that runs through the front and back and extends in the transverse direction is provided on the rear wall of the air supply duct. The fresh air duct 34 includes an air supply section 342 and a uniform wind section 344 .

[0068] One end of the air supply section 342 is connected to the fan chamber 32B, and the other end extends to the rear wall of the air supply duct. The uniform air section 344 is connected to the air supply section 342 and is arranged in the uniform air slot 22B; a fresh air outlet is opened in the horizontal direction on the front side of the uniform air section 344 to connect to the air supply duct.

[0069] Figure 4 A portion of the duct member 22 is shown schematically, including the rear wall of the air supply duct. Figure 4 It can be seen that the indoor unit 20 of the air conditioner of this embodiment is provided with not only a mounting port 22A for inserting the filter module 40 on the rear wall of the air supply duct, but also an air uniforming groove 22B for setting the air supply duct. The air uniforming groove 22B is connected front to back on the rear wall of the air supply duct, so that the fresh air duct 34 can be detachably connected to the duct member 22 along the front-to-back direction, and the fresh air outlet of the fresh air duct 34 faces the inside of the air supply duct.

[0070] The air supply section 342 of the fresh air duct 34 extends to the rear wall of the air supply duct, and may abut against the rear wall of the air supply duct, or may partially extend into the rear wall of the air supply duct so as to fix the fresh air duct 34 relative to the duct member 22. Figure 5 As shown, the uniform wind section 344 of the fresh air duct 34 corresponds to the shape of the uniform wind slot 22B on the rear wall of the air supply duct, so that it can be set in the uniform wind slot 22B. The uniform wind section 344 extends laterally along the rear wall of the air supply duct, and a fresh air outlet extending laterally is opened on the front side, so that the fresh air delivered to the air supply duct by the fresh air module 30 can be evenly distributed in the horizontal direction.

[0071] Since the fresh air is blown into the air supply duct instead of being directly blown out of the air conditioner indoor unit 20, the air conditioner indoor unit 20 of this embodiment can blow out the mixed air formed by the air flow after heat exchange and the fresh air by controlling the air supply fan and the fresh air module 30 arranged in the air supply duct to work simultaneously, so that the blown air flow can be mixed with the fresh air from the outside while cooling or heating is performed.

[0072] Figure 6 yes Figure 1 The schematic cross-sectional view of the fresh air duct 34 of the indoor unit 20 of the air conditioner is shown.

[0073] In some optional embodiments, the fresh air duct 34 also includes: a plurality of air guide ribs 346.

[0074] A plurality of air guide ribs 346 are arranged in the air uniforming section 344 at intervals along the transverse direction to divide the fresh air outlet into a plurality of sections at intervals along the transverse direction. The rear end of each air guide rib 346 is spaced from the rear wall of the air uniforming section 344 and is bent toward the air supply section 342 .

[0075] refer to Figure 6 As shown, the fresh air outlet defined by the uniform wind section 344 of the present embodiment is divided into multiple sections with transverse intervals by a plurality of wind guide ribs 346, and the rear ends of the wind guide ribs 346 separating the fresh air outlet are bent toward the air supply section 342, thereby guiding the airflow and reducing the wind speed loss and airflow disturbance caused by the fresh airflow blowing directly onto the panel surface.

[0076] In some optional embodiments, the width of the interval between the rear end of each air guide rib 346 and the rear wall of the uniform wind section 344 is different, and the interval width between the rear end of the air guide rib 346 and the rear wall of the uniform wind section 344 is configured to be smaller the farther the distance from the air supply section 342 is. By adjusting the width of the interval between the rear end of the air guide rib 346 and the rear wall of the uniform wind section 344, the air outlet volume of each fresh air outlet can be adjusted, and the air outlet effect of the fresh air outlet in the lateral direction can be made more uniform.

[0077] In some optional embodiments, the fresh air filter chamber 32A is located above the fan chamber 32B.

[0078] refer to Figure 5 As shown, the fresh air filter chamber 32A of this embodiment is located above the fan chamber 32B. Accordingly, the fresh air duct 36 is connected to the upper part of the module body 32 and transports the fresh air to the upper fresh air filter chamber 32A, and then the fresh air enters the fan chamber 32B downward. In some optional embodiments, the fresh air fan can be a centrifugal fan, and the air is axially inlet in the up and down directions and radially outlet. The fresh air module 30 of this embodiment arranges the fresh air filter chamber 32A and the fan chamber 32B up and down so that the position of the installation port 22A on the air duct component 22 does not affect the setting of the uniform air section 344 of the fresh air duct 34, that is, Figure 4 As shown, the mounting opening 22A and the air uniforming slot 22B are also arranged up and down on the rear wall of the air supply duct.

[0079] Furthermore, the indoor unit 20 of the air conditioner of the present embodiment can be further configured as follows: Figure 4 As shown, the installation opening 22A is located above the air uniforming slot 22B, so that the fresh air outlet of the fresh air module 30 is close to the lower part of the air outlet of the air conditioner indoor unit 20, and the fresh air flow has a smaller turbulent effect on the heat exchange air flow in the air supply duct.

[0080] Figure 7 yes Figure 1 Schematic diagram of the filter module 40 of the air conditioner indoor unit 20 is shown.

[0081] In some optional embodiments, the shape of the front surface of the operating portion 44 is adapted to the shape of the rear wall of the air supply duct at the mounting opening 22A.

[0082] In order to avoid the shape of the detachable filter module 40 from significantly affecting the air supply effect of the air supply duct, the shape of the front surface of the operating part 44 of the filter module 40 of this embodiment is adapted to the shape of the rear wall of the air supply duct at the mounting port 22A, that is, the front surface of the operating part 44 has the same bending shape as the rear wall of the air supply duct at the mounting port 22A.

[0083] In some optional embodiments, a groove is formed on the front surface of the operating portion 44. The filter module 40 further includes an operating rod 46. The operating rod 46 is disposed in the groove of the operating portion 44.

[0084] refer to Figure 7 As shown, in order to facilitate the disassembly of the filter module 40, the air conditioner indoor unit 20 of this embodiment is also provided with an operating lever 46 on the front surface of the operating part 44. The operating lever 46 can be used as a handle when the user extends his hand or an operating tool into the air supply duct, thereby assisting in the disassembly of the filter module 40.

[0085] The operating lever 46 is disposed in a groove formed on the front surface of the operating portion 44 , thereby reducing the impact on the surface shape of the operating portion 44 and avoiding the impact on the air supply effect of the air supply duct.

[0086] In some optional embodiments, the groove of the operating portion 44 is opened on the front surface of the operating portion 44 in the lateral direction. And one lateral end of the operating rod 46 is rotatably connected to the operating portion 44 .

[0087] refer to Figure 7 As shown, in order to make the filter module 40 easier to disassemble, the operating rod 46 is further arranged to be rotatable in this embodiment and is arranged on the operating portion 44 in a lateral direction, so that it can be disassembled as shown in FIG. Figure 7 The dotted line position schematically rotates to one end toward the air outlet, making it easier for the user to remove the filter module 40 by hand.

[0088] In some optional embodiments, the operating rod 46 does not protrude from the front surface of the operating portion 44 .

[0089] In order to further avoid affecting the air supply effect of the air supply duct, the operating rod 46 of this embodiment does not protrude from the front surface of the operating portion 44. In particular, the front surface of the operating rod 46 can be connected to the front surface of the operating portion 44 in the longitudinal direction, and spaced from the front surface of the operating portion 44 in the lateral direction, so that the user can pull the operating rod 46 from the lateral end.
