Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] An air conditioning fan is arranged in the air conditioning inner unit housing of the square cabinet air conditioner. A filter screen and an air conditioning air inlet grille are fixedly arranged at the air inlet of the air conditioning inner unit housing through fixing parts in sequence. External airflow enters the air conditioning fan through the air conditioning air inlet grille and the filter screen in sequence.

[0048] When the air conditioner fan of the cabinet air conditioner fails, the maintenance personnel need to remove the air inlet grille and the filter screen in turn, and then repair the air conditioner fan located in the air conditioner inner casing. In the prior art, no matter how serious the failure is, the air conditioner must be disassembled in the same process.

[0049] Every time the existing square cabinet air conditioner is repaired, the air inlet grille and the filter need to be disassembled. Since the air inlet grille and the filter are fixed at the air inlet by fixing parts respectively, and the air inlet grille and the filter are large in size and heavy in weight, it is time-consuming and laborious to disassemble the air inlet grille and the filter. After the air conditioner motor is repaired, the filter and the air inlet grille need to be installed again, resulting in low maintenance efficiency of the air conditioner fan.

[0050] In order to solve the technical problem of low maintenance efficiency of existing air-conditioning fans, the present application proposes an air-conditioning air inlet grille, an air-conditioning indoor unit and an air conditioner, wherein the air-conditioning air inlet grille includes an air inlet grille body, the air inlet grille body is used to cover the air inlet of the air-conditioning indoor unit casing, and the air inlet grille body is provided with a fan inspection port and an inspection port cover plate, the fan inspection port is used to correspond to the air-conditioning fan in the air-conditioning indoor unit casing, and the inspection port cover plate is detachably connected to the fan inspection port to open and close the fan inspection port.

[0052] Due to the use of the air-conditioning air inlet grille of the present application, when the air-conditioning fan needs to be repaired, there is no need to remove the air-conditioning air inlet grille and the filter from the air-conditioning inner casing, and the inspection port cover is smaller in size and lighter in weight than the air inlet grille body. When repairing the air-conditioning fan in the prior art, it is necessary to disassemble the air-conditioning air inlet grille and the filter in turn, while the air-conditioning air inlet grille of the present application only requires disassembling the inspection port cover to repair the air-conditioning fan, thereby reducing the number of parts that need to be disassembled, and because the inspection port cover is smaller in size and lighter in weight than the air-conditioning air inlet grille, the maintenance efficiency of the air-conditioning fan is improved.

[0053] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

The air inlet grille body 100 is used to guide the external air flow to the air inlet 1100 so that the air-conditioning fan 1200 in the air-conditioning inner unit housing 1000 can operate normally.

[0057] A fan inspection port 200 and an inspection port cover 300 are provided on the air inlet grille body 100. When the air conditioner is in normal use, the inspection port cover 300 is placed on the fan inspection port 200 to close the fan inspection port 200. When the air conditioner motor needs to be repaired, the inspection port cover 300 is removed from the fan inspection port 200. Because the fan inspection port 200 is correspondingly connected to the air-conditioning fan 1200 in the air-conditioning inner unit casing 1000, the maintenance personnel can repair the air-conditioning fan 1200 through the fan inspection port 200, and can also take the air-conditioning fan 1200 out of the air-conditioning inner unit casing 1000 through the fan inspection port 200.

[0058] Due to the use of the air-conditioning air inlet grille of the present application, when the air-conditioning fan 1200 needs maintenance, there is no need to remove the air-conditioning air inlet grille and the filter from the air-conditioning inner unit casing 1000, and the inspection port cover 300 is smaller in size and lighter in weight than the air inlet grille body 100. When the air-conditioning fan 1200 is currently being repaired, it is necessary to disassemble the air-conditioning air inlet grille and the filter in turn, while the air-conditioning air inlet grille of the present application only requires disassembling the inspection port cover 300 to repair the air-conditioning fan 1200, thereby reducing the number of parts that need to be disassembled, and because the inspection port cover 300 is smaller in size and lighter in weight than the air-conditioning air inlet grille, the maintenance efficiency of the air-conditioning fan 1200 is improved.

[0059] In another embodiment, the air inlet grille body 100 includes a first side panel 110, a front panel 120 and a second side panel 130 connected in sequence, wherein the first side panel 110 is used to form a side surface of at least a portion of the air conditioner inner unit casing 1000, the front panel 120 is used to form the front surface of at least a portion of the air conditioner inner unit casing 1000, and the second side panel 130 is used to form the other side surface opposite to at least a portion of the air conditioner inner unit casing 1000, and a plurality of air inlet windows 140 are provided on the first side panel 110 and the second side panel 130, and the air inlet windows 140 are used to guide external airflow to the air conditioner fan 1200, and the fan inspection port 200 is provided on the front panel 120.

[0060] In this embodiment, the shape of the air inlet grille body 100 matches the air inlet 1100 on the air conditioner inner housing 1000.
