Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a fan blade pressure plate and an air conditioner. Background Art

[0002] A traditional wall-mounted air conditioner usually has only one fan blade inside. The fan blade extends along the length of the casing so that the wind is blown out perpendicular to the length of the casing. The air outlet range is small, and it is necessary to use an air guide plate or a swing blade to expand the air outlet angle. Since only one fan blade cannot supply air in multiple directions, the wall-mounted air conditioner uses double fan blades, and there are still the following technical problems: when the double fan blades extend too long along the length of the casing, the double fan blades are prone to vibrate, so the position of the double fan blades needs to be constrained; when the evaporator is too long, the evaporator is prone to deformation in the middle position, causing the condenser to be closer to the double fan blades in the middle position. If the formed condensed water is not discharged in time, there is a risk of being sucked into the air duct by the wind pressure, causing damage to the air conditioning components, thereby affecting the performance and comfort of the air conditioner and reducing the user experience.
