Description

Air-out structure of air conditioner type range hood

Technical Field

The utility model relates to a range hood, in particular to an air outlet structure of an air-conditioning type range hood.

Background

The kitchen is the main place that people cook, and the cooking experience is directly influenced by the kitchen air environment. The kitchen is hot in summer and cold in winter, and has the demand of cooling and heating, therefore, people invent the range hood integrated with the air conditioning function, cool the kitchen air in summer, and provide warm air for the kitchen in winter so as to improve the cooking comfort level. The current integral kitchen air conditioner lampblack absorber generally sets up the air outlet on the cupboard cabinet door, makes the air outlet imbed in the cupboard, and the wholeness is better, but because the air outlet is higher, because the angle reason stands before the lampblack absorber the cold wind and blows not to or blow the overhead, influences user's travelling comfort, and cold wind effect is relatively poor, and the air-out distance is far away, makes the air-out temperature of user's perception higher, and no cool sense. In order to achieve good human experience effect, cold air needs to be blown downwards, local pressure is low due to the fact that the flow speed is high, and oil smoke can be sucked by local low pressure to discharge smoke. The existing scheme does not interfere with the oil smoke absorbing effect when cold air is blown to a person by adjusting the wind direction through the wind guide plate of the air outlet, but the degree has strong correlation with the wind speed, namely, the higher the wind speed is, the lower the local pressure is, the higher the angle is, so that the influence on the oil smoke absorbing effect is avoided. The wind speed is related to the wind outlet area, and the smaller the wind outlet area is, the larger the wind speed is under the condition of a certain wind quantity. The appearance of the product is affected to a certain extent, the appearance is bulked due to the fact that the air outlet is too wide, and the angle of the air deflector is required to be increased due to the fact that the air outlet is too narrow, so that user experience is affected. The width of the existing air outlet is generally within 500mm, a left air guide mechanism and a right air guide mechanism are not arranged, the air outlet area is narrower, the air outlet direction is controlled by the upper and lower pendulum air of the air guide door, and cold air is difficult to blow in the left and right directions. In addition, the air outlet frame of the existing air outlet structure is required to be independently installed on the upper edge of the cabinet and cannot be installed together with the whole machine.
