Description

Range hood with dehumidification function

Technical Field

The invention relates to a range hood, in particular to a range hood with a dehumidification function.

Background

A range hood has become one of the indispensable kitchen appliances in modern households, and generally, the range hood includes a top suction type and a side suction type. The range hood works by utilizing the fluid dynamics principle, and the range hood sucks and discharges oil smoke through a centrifugal fan arranged in the range hood and filters part of grease particles by using a filter screen. One of the drawbacks of Chinese cooking is that the cooking fumes in the kitchen are large, and in order to discharge the cooking fumes in the kitchen as soon as possible, people often use a range hood. However, most of the prior art range hoods generally have only a function of exhausting oil smoke, and cannot adjust the humidity of a kitchen.

In our life, the most common use of dehumidification technology is on dehumidifiers, which can reduce indoor humidity. The principle of the dehumidifier is that the fan pumps the moist air into the dehumidifier and passes through the heat exchanger, at the moment, the moisture in the air condenses into water drops, and the water drops become dry air to be discharged out of the dehumidifier, and the indoor humidity is reduced by circulation. The problems that the circuit is affected by damp and tableware mildews due to overlarge ambient humidity and electrical appliances are easy to occur exist in the household kitchen, and the dehumidification technology is required to be applied to solve the problems, meanwhile, the space is limited due to the fact that most household kitchen spaces are limited, and if the electrical appliances such as a dehumidifier are added again, the space is narrower, and user activities are hindered.

The existing range hood with the dehumidification function is usually fixedly installed and cannot be adjusted in height, but the optimal installation positions are different when different functions of dehumidification and oil smoke suction are respectively used, and the effect is poor if the positions are not adjustable. If the range hood is used as a range hood, the range hood needs to be in mid-air, at least the height of the range hood is higher than that of a cooking bench, and a good use effect can be achieved.
