Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an air-conditioning type range hood. Background Art

[0002] In order to improve the user's cooking experience, people have invented various air-conditioning hoods to provide cold air to the kitchen in summer and warm air in winter. The air-conditioning hood integrates the air-conditioning component with the range hood, and an air-conditioning outlet is opened on the shell of the range hood. The air-conditioning hood can work in multiple different modes. As long as the air-conditioning mode is turned on, the air-conditioning outlet will blow out cold air or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cook's cooking experience. For the air-conditioning hood working in the cooling mode, in order to improve the energy efficiency of the air conditioner, people have designed a structure in which the condenser is installed in the exhaust channel. The exhaust channel also constitutes a heat dissipation channel, that is, the heat of the condenser is taken away by the oil smoke, and the condenser is dissipated to improve its heat exchange effect. Since the condenser temperature is high, if it is only dissipated by the oil smoke airflow, the heat dissipation effect is not good. For this reason, people have invented a structure that uses air-conditioning condensed water to dissipate heat from the condenser, that is, the air-conditioning condensed water is transported to the surface of the condenser, and the condensed water is used to reduce the surface temperature of the condenser, thereby improving its heat exchange effect.

[0003] For example, the Chinese utility model patent with patent number CN202320196584.9 (publication number CN219550622U) discloses a refrigeration-type range hood, which includes an upper box and a lower cavity. An air conditioner module is provided outside the upper box. The upper box is divided into a smoke exhaust cavity and a heat dissipation cavity. A smoke exhaust fan is installed in the smoke exhaust cavity. The heat dissipation cavity is connected to the smoke exhaust cavity through a heat dissipation outlet. A condenser is installed in the heat dissipation cavity. The condensed water condensed on the evaporator can drip onto or be transported to the condenser. A heat dissipation fan and a water pump are installed below the condenser. The heat dissipation fan and the water pump are coaxially arranged and rotated under the drive of the same motor. The condensed water that has not been consumed by the condenser is pumped back to the condenser through the water pump or discharged to the outside of the upper box. The condensed water that has not been consumed by the condenser in the refrigeration range hood can be pumped back to the condenser through the water pump, and continue to rely on the high temperature of the condenser surface for heat exchange and evaporation consumption, or it can be discharged to the outside of the upper box through the water pump.

[0004] The cooling fan is used to dissipate heat from the condenser, but the rotation speed of the cooling fan has a great influence on the cooling effect of the condenser. If the rotation speed is too fast or too slow, it will affect the condensation temperature of the condenser and the evaporation temperature of the condensed water, thus affecting the heat exchange effect of the condenser.
