Alternatively, the grill assembly 200 includes a peak plate 210 and a valley plate 220, which are continuously bent in the width direction of the grill panel 100. The connection between the peak plates 210 and the valley plates 220 is achieved by connecting grid plates 230. In this way, an airflow path for air can be defined between adjacent connecting grid plates 230. After passing through the air flow path, the air is circulated toward the other side of the grill panel 100 through the air inlet hole 231. In this process, the air collides with the side walls of the connection grill plates 230, which face the air inlet direction, impurities (e.g., dust, oil, etc.) entrained in the air are separated and can flow down along the side walls of the connection grill plates 230 to the valley plates 220 to be collected, preventing foreign materials from flowing into the interior of the air conditioner. Therefore, the air inlet structure in the embodiment of the disclosure realizes the integration of the air inlet grille and the filtering structure, reduces components, reduces the cost, simplifies the assembly difficulty, and is easy to disassemble, assemble and clean. In addition, under the condition that the air inlet structure is arranged in the kitchen air conditioner, oil stain impurities can flow to the extension plate along the wall surface of the connecting grid plate 230 to be collected, so that accumulation of oil stains at the air inlet hole 231 is prevented, and the air inlet quality and the operation energy efficiency of the kitchen air conditioner are improved.

On one hand, the air inlet structure can enable air to flow into the indoor unit of the air conditioner through the air inlet structure, and on the other hand, when the air flows through the air inlet holes 231, oil stain impurities in the air can be filtered out. Therefore, the integration of the grille and the filter screen is realized, the number of structural parts of the air inlet 310 of the air conditioner is reduced, and the air conditioner is convenient to disassemble, assemble and clean. In addition, oil stain impurity can flow to the extension plate along the wall surface of connecting grid plate 230 and is collected to prevent the accumulation of oil stain in fresh air inlet 231, improve air inlet quality and the operation efficiency of air conditioning indoor unit.

Thus, in the case that the width of the peak plate 210 and the width of the valley plate 220 are equal, the air flow channel formed between the adjacent connection grid plates is narrowed, thereby promoting the increase of the flow velocity of the air to facilitate the rapid flow of the air through the air inlet holes 231 and the separation between the air and the impurities contained therein. Preferably, the angle between the connecting grid plate 230 and the extension plate 240 is 60 °.

In some embodiments, the peak and valley plates 210, 220 are both rectilinear panels parallel to the grid panel 100, or the peak and valley plates 210, 220 are both arcuate panels that curve away from the connecting grid plate 230.

Optionally, the peak and valley plates 210, 220 are both rectilinear panels parallel to the grid panel 100. Thus, the flatness of the grille panel 100 is facilitated, and the aesthetic appearance of the air inlet structure is improved.

Alternatively, the peak and valley plates 210, 220 are both arcuate panels that curve away from the connecting grid plate 230. In this way, a reverse flow action of air can be achieved, and air can smoothly flow from the windward side 110 of the grille panel 100 into the airflow passage.

The folded edge 250 is disposed at an end of the extension plate 240 facing away from the wave trough plate 220 and is folded upward toward the wave trough plate 210. Thus, an outflow channel through which air flows out from the air inlet 231 can be formed between the remaining connection grid plates 230 of the folded edge 250, so that the air collides with the extension plate 240 and then flows along the outflow channel to the wave crest plate 210 and then collides again, thereby achieving the turning, and facilitating the air to flow toward the inside of the indoor unit of the air conditioner.

In some embodiments, the flaps 250 are bent upward at an angle of 0 to 75 degrees from the connecting grid plate 230.

Alternatively, where the angle between the flange 250 and the connecting grid plate 230 is 0 °, the two are parallel. In this way, an airflow channel parallel to the connecting grid plate 230 can be defined, so that the air can smoothly move to the side wall of the wave plate 210 after impacting the extension plate 240 along the channel, so as to change the movement track by impacting again, which is beneficial to make the air continue to flow along the direction perpendicular to the wave plate 210, and the stability of the air movement is ensured.

Alternatively, where the angle between the flap 250 and the connecting grid plate 230 is greater than 0 ° and equal to or less than 75 °, an airflow path can be defined that is angled with respect to the connecting grid plate 230.
