Description

Technical Field

[0001] The utility model relates to the technical field of duct machines, in particular to a water receiving tray for duct machines. Background Art

[0002] Duct air conditioner is the abbreviation of duct air conditioner, which is a type of central air conditioner. Duct air conditioner generally includes a casing, a water tray, a heat exchanger, and an air supply assembly arranged in the casing. The water tray is located below the heat exchanger to collect the condensed water generated during the operation of the heat exchanger.

[0003] The existing water tray is fixed in the casing by screws, and has a simple structure. However, the existing duct machine equipment is set in a suspended ceiling environment. When the equipment is running for a long time, dust, flocs and other substances will inevitably remain in the water tray, which is easy to cause blockage after long-term use. In severe cases, it will cause rust, leakage and other problems. If the duct machine leakage is not discovered in time, it will further cause irreversible effects on the ceiling, causing water stains and mildew on the ceiling, and will also cause problems such as falling off, greatly affecting indoor safety. When professional maintenance personnel are asked to handle it, the ceiling needs to be repaired separately for cleanliness and beauty, causing additional economic losses.

[0004] Therefore, a ducted air conditioner water tray is proposed, which can promptly send out an alarm when the water tray is blocked to remind the user to repair it, so as to avoid long-term water accumulation or excessive water accumulation in the water tray, which may cause greater economic losses.
