Description

Technical Field

[0001] The utility model relates to the technical field of fan coil units, and in particular to a household exposed fan coil unit. Background Art

[0002] Fan coil units are commonly used cooling and heating terminal devices. They are one of the terminal devices of air conditioning systems, consisting of a small fan, a motor and a coil (air heat exchanger). Exposed fan coil units are a type of indoor heating equipment, usually without an outdoor unit. They are generally installed on walls, ceilings or on the floor, and use indoor air to circulate and heat through the fan coil units, directly heating the indoor space. Compared with traditional heating equipment, exposed fan coil units eliminate the need to install an outdoor unit, making installation easier and saving space.

The box body is a rectangular box-shaped structure, and a hanging back plate is fixed to one side of the box body by screws arranged on the outer periphery of the box body. Two sets of hanging holes are symmetrically opened above the hanging back plate away from the box body. An adjustable air outlet louver is movably installed above the side of the box body away from the hanging back plate, and a touch screen is installed on the box body below the air outlet louver. A motor is fixedly installed at the position corresponding to the air outlet louver inside the box body. This patent drives the wind wheel to rotate through the entire box body through a motor, so that the area of ​​contact between the evaporator in the box body and the wind is increased, thereby achieving efficient temperature regulation. However, this patent still has the following disadvantages:

[0004] The wind is driven by a motor to rotate the fan wheel so that the wind passes through the entire box, which increases the contact area between the evaporator in the box and the wind. However, the contact area between the heat dissipation window and the dust also increases at the same time. Under long-term exhaust and return air, dust is easily accumulated on the heat dissipation window of the box, which affects the heat exchange between the chilled water and the hot air during the air supply process, causing the air temperature to drop and affecting the use effect.
