Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, and particularly relates to a fresh air type range hood. Background Art

[0002] Range hoods can be classified into two major categories: European style and Chinese style according to their conditions. European style range hoods are mainly wall-mounted, and there are also some high-end island type products; Chinese style range hoods are mainly wall-mounted, including deep hood type and shallow hood type. According to the number of motors and wind wheels, they can be divided into: double motors and single motors (i.e., double cylinders and single cylinders). From the way of accumulating and draining oil, they can be divided into double oil circuits and triple oil circuits (oil draining in the air chamber, oil draining in the protective cover, and oil draining by air transportation). From the structure of the smoke collecting chamber, there are single-layer (triple oil circuit), double-layer inner type (double oil circuit), multi-layer collecting net (multi-oil circuit), etc. From the functional structure, they can be divided into multimedia range hoods, built-in range hoods, wall suction type, side suction type range hoods, solid wood type range hoods, etc.

[0003] The existing range hood can only suck the cooking fumes at the cooking position, and the air at the cooking position is passively supplemented by the pressure difference, resulting in poor circulation effect. Content of the Utility Model

[0004] In order to make up for the deficiencies in the prior art, the utility model provides a fresh air type range hood, which can actively supplement the air at the cooking position, improve the air circulation effect and the fume extraction efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A fresh air type range hood includes a housing. The housing is provided with a fume suction hole. A blower is arranged inside the housing at the front top of the fume suction hole, and an air inlet hole is arranged on the housing above the blower. A wind guiding structure with an adjustable angle is arranged on the housing below the blower.

[0007] Further, the wind guiding structure includes a fixed seat and a wind guiding plate. One end of the wind guiding plate is rotatably connected to the fixed seat, and the other end is connected to the fixed seat through a damper.

[0008] Further, a plurality of parallel wind guiding grooves are arranged on the wind guiding plate.

[0009] Further, the blower includes an air duct, a wind wheel, and a motor. Fixed brackets are connected to both sides of the air duct. After a silica gel pad is connected to the bottom of the fixed brackets, they are fixedly connected to the housing. The wind wheel is arranged inside the air duct. One end of the wind wheel is connected to the air duct through a bearing, and the other end is connected to the motor fixed outside the air duct through a wind wheel rubber ring.

[0010] Further, a plurality of air inlet holes are arranged and arranged in a grid shape.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] For the fresh air type range hood of the utility model, by arranging a blower and a wind guiding structure at the front end of the housing, the air at the top of the housing can be conveyed to the cooking position, realizing the circulation of the air at the cooking position. Meanwhile, the gas pressure difference at the cooking position is increased, and the oil fume extraction efficiency can be effectively improved. Description of the Drawings

[0018] Many specific details are set forth in the following description in order to provide a thorough understanding of the utility model. However, the utility model can be implemented in many other ways different from this description, and those skilled in the art can make similar extensions without departing from the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below.

[0019] Embodiment 1

[0020] As Figure 1 , 2 shown, a fresh air type range hood includes a housing 1, and the housing 1 is provided with oil fume suction holes 11. A blower 2 is arranged inside the housing 1 at the top of the front end of the oil fume suction holes 11, and an air inlet hole 12 is provided in the housing 1 above the blower 2, and an adjustable angle wind guiding structure 3 is provided in the housing 1 below the blower 2. Through the cooperation of the blower 2 and the wind guiding structure 3, the air at the top of the housing 1 can be conveyed to the lower part of the housing 1 during use, so that the air at the cooking position is circulated. The air inlet holes 12 are provided in multiple numbers and arranged in a grid shape to ensure sufficient air intake.
