Description

Smoke baffle and range hood with same

Technical Field

The utility model relates to a range hood, in particular to a smoke baffle and a range hood with the smoke baffle.

Background

With the continuous improvement of the requirements of people on the quality of household life, the range hood is continuously improved as a kitchen tool necessary for families. Because the range hood is far away from the pot generating the oil smoke, the oil smoke rising above the pot is easy to escape from the two sides of the smoke collecting cover, and the oil smoke suction effect is poor. In order to prevent the oil smoke from escaping and improve the oil smoke absorption effect of the range hood, the existing range hood is provided with a smoke baffle plate or a smoke guide plate, the structure of the existing smoke baffle plate is different, for example, the Chinese utility model with the patent number of 20172042124.1 (the publication number of CN 207065683U) discloses a smoke guide plate of a range hood, the smoke guide plate comprises a smoke guide plate body and an oil collection part arranged at the rear part of the smoke guide plate body, although, the structure of the smoke guide plate is very simple, the oil collection capacity of the smoke guide plate can be improved due to the existence of the oil collection part, the condensed oil on the smoke guide plate body is reduced, the cleaning period of a user is prolonged, the use is convenient and the practicability is strong, but the structure is common, and the smoke guide plate of the structure is usually on a metal smoke guide plate, and the appearance degree is still to be further improved.

In addition, the range hood has many types, and can be divided into two types, namely, a fan upper type and a fan lower type according to the difference of the positions of the installed fans in the casing, namely, for an operation panel of the range hood, the fan is completely positioned above the operation panel and is called as the fan upper type, the fan is completely positioned below the operation panel and is called as the fan lower type, and the height design of the operation panel needs to be based on the height suitable for a user and convenient operation. For example, "secondary extractor hood with kitchen air purifying function" disclosed in the chinese utility model patent with patent number ZL95202124.2 (publication number CN2229615Y) and "extractor hood with kitchen air purifying function" disclosed in the chinese utility model patent with patent number ZL201120225844.8 (publication number CN202133011U) all disclose an extractor hood with a fan disposed on top. The range hood has the advantage of large operation space for users, and accords with the international safety standard, and has the defect of poor range hood effect due to the fact that the distance between the fan system and the table surface of the stove is too far. For example, chinese patent application No. zl93100778.x (publication No. CN1084263A) discloses an exhaust hood with a bottom-mounted fan, which has a bottom-mounted fan, and the height of an operating panel is fixed, so that the whole casing extends downward along the operating panel, and the lower part of the casing is close to the top of a kitchen range, although the effect of sucking oil smoke is not good, the noise is relatively large, and the operating space of a user is greatly reduced. In conclusion, the structure of the existing range hood needs to be further improved.
