Problems solved by technology
[0004] The above-mentioned existing box-type air-guiding box 2' utilizes the principle of a right-angle tee, and when the wind of the air outlet is upward, there is a phenomenon of right-angle turning in the box-type air-guiding box 2', while the air-guiding box 2 The internal space structure is limited, resulting in a large wind resistance in the connecting pipe 3', and the direct blow to the top of the air guide box 2', forming local noise; in addition, although the left and right air outlets are set, due to the high wind speed , the refraction of the airflow is actually formed on the upper top of the air guide box 2', and there is a phenomenon of downward airflow, which affects the user experience, and at the same time forms turbulent interference to the stove for cooking with an open flame; at the same time, the left and right sides are horizontally If the wind area is too small, it is easy to cause blockage of the air outlet channel, increase the exhaust resistance of the fan system, and increase the noise

Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] see Figure 1 to Figure 5 , an internal circulation range hood, comprising a range hood main body 1 and an air outlet device 2, the back of the range hood main body 1 is connected and fixed to a back wall 100, the range hood main body 1 includes a smoke collection hood 11, arranged on a smoke collection The fan cover 12 above the cover 11 and the fan system 13 arranged in the fan cover 12 , the air outlet device 2 is arranged above the air outlet on the top of the fan cover 12 of the range hood main body 1 .
[0030]The air outlet device 2 includes a hollow decorative cover 21 , an air deflector 22 , a front filter 23 and a side filter 24 . The decorative cover 21 includes a left side wall 211, a right side wall 212, and a front side wall 213 connected between the front ends of the left side wall 211 and the right side wall 212. The le...

The invention discloses an air discharging device. The air discharging device comprises a hollow decorative cover, and is characterized in that a bottom opening of the decorative cover is used for airadmission, the top of the decorative cover is provided with an air guide plate, the air guide plate comprises a top plate, the left side, the right side and the front side of the top plate are tightly attached to corresponding positions of the decorative cover, the top plate is gradually inclined upwards from the rear to the front, an air discharging port is formed in the decorative cover, and the top end of the air discharging port is not higher than the top plate. The invention also disclosed an internal circulation range hood using the air discharging device. By arranging the inclined upward air guide plate, airflow from the bottom of the decorative cover can expand and flow forward starting from a contact point of the decorative cover and the air guide plate along an inclined surface,so that the larger wind resistance noise formed by backward flowing and impact of a back wall is avoided.
Description
technical field [0001] The invention relates to a cooking fume purification device, in particular to an air outlet device and an internal circulation range hood using the air outlet device. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. According to the fume discharge method, range hoods can be divided into external discharge type and internal circulation type. The current internal circulation range hood mainly inhales the oil fume and air through the fan system, absorbs and filters the filter system in the whole machine, and then discharges the purified air into the room. Because the exhaust air volume is large, if it is directly discharged, the discharged When the air flow is directly blown to the ceiling, it will form a rebound and return flow, and the downward air supply will interfere with the user's cooking. Therefore, a box-type air outlet device is generally added, and the upward air from the air...
