Description

Air-conditioning type range hood and control method thereof

Technical Field

The invention relates to a range hood, in particular to an air-conditioning type range hood and a control method thereof.

Background

In the prior art, an air-conditioning type range hood with various structures is disclosed, namely, an air conditioning component is added on the basis of a range hood platform, so that all functions of the range hood can be realized, and meanwhile, the functions of an air conditioner can be realized. The existing range hood with a plurality of refrigerating functions arranges a condenser in a lampblack channel, and exchanges heat by utilizing air with lampblack sucked by a fan. When the refrigeration system is started, wind exhausted by the fan of the range hood is blown to the condenser, and because the wind contains a plurality of oil smoke particles, in order to keep the surface of the condenser clean, an additional electrostatic device is often required to filter the fine particles, thereby increasing the cost and bringing the risk of errors. Meanwhile, the internal space of the range hood is relatively narrow, and the space arrangement requirement becomes higher. In addition, the electrostatic device often cannot completely remove oil smoke particles in wind, so that when wind of a fan blows to the condenser, the surface of the condenser is polluted, and the working efficiency and the service life of the condenser are reduced. In addition, by adopting the scheme, a smoke tube three-way device is needed to be added, namely, when the refrigerating system does not work, the air exhausted by the range hood is exhausted from a normal channel. When the refrigerating system works, the air valve is opened, and air of the range hood is blown to the condenser through the other channel. Because the air discharging paths under two working conditions need to be considered, two holes are avoided from being punched on the wall, and the air discharged from the two paths needs to be finally converged together and discharged out of the room. The added tee joint device increases the cost relative to a single smoke pipe, and is unfavorable for the discharge of the oil smoke because the smoke pipe is more bent. In addition, in the air conditioning type range hood, under a refrigerating mode, outdoor air can blow out cold air from an air outlet after heat exchange, a large amount of condensed water can be condensed on the surface of an evaporator, and normally, the condensed water is directly discharged outdoors through a drain pipe, so that the condensed water is not effectively utilized. Although the conventional air conditioning type range hood discloses a scheme of radiating heat of a condenser by using condensed water, intelligent control cannot be performed on the utilization of the condensed water, and the utilization efficiency of the condensed water needs to be improved. In view of the above, there is a need for further improvements in existing air conditioning hoods.
