Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a range hood. Background Art

[0002] Range hoods, an essential appliance in modern kitchens, typically use their negative pressure to absorb cooking fumes and exhaust them outdoors. As we all know, cooking not only produces fumes but also generates a significant amount of heat. While range hoods effectively remove fumes, they don't effectively circulate air in the kitchen, effectively preventing the heat from cooking. This leads to high kitchen temperatures, especially after prolonged cooking, which can cause the temperature to rise dramatically. In the summer, the high temperatures can be unbearable.

[0003] Faced with the scorching summer heat in the kitchen, people often use tools like floor fans to cool down. However, the wide horizontal airflow of floor fans can be uncomfortable and significantly impact the range hood's ability to extract oil fumes. The chaotic airflow generated by floor fans also encourages the escape of oil fumes, which can easily hit people's faces and spread throughout the kitchen, even into other rooms. Furthermore, floor fans and other cooling tools themselves cannot effectively isolate cooking fumes. Over time, the fumes they collect are extremely difficult to clean, and the air they blow out is accompanied by a smell of oil fumes.

[0004] In the related art, in order to solve the problem of oil smoke escaping caused by the chaotic wind field generated by the floor fan, a fan module is usually set on the range hood. Although the heat can be dissipated by blowing air toward the cook through the air outlet of the fan module, when the fan module is turned on, the negative pressure of the air flow generated at the air inlet of the fan module can easily attract the oil smoke to the outside of the range hood, which may cause the oil smoke to hit the face in severe cases. Utility Model Content

[0005] In view of this, the present invention provides a range hood to solve the problem that when a fan module is installed on the range hood, the negative pressure of the air flow generated by the air inlet of the fan module easily draws the oil smoke to the outside of the range hood, which may cause the oil smoke to hit the face in serious cases.

[0006] The utility model provides a range hood, comprising:

[0007] Range hood body;

[0008] A decorative cover is arranged on the top of the range hood body and has a range hood air duct inside;

[0009] A fan module is arranged on the top of the range hood body. The fan module includes an air inlet and an air outlet. The air outlet is located in the front, and the air inlet is arranged in the decorative cover and isolated from the range hood air duct.

[0010] Beneficial effect: A fan module is arranged on the top of the range hood body, and the air outlet of the fan module is located in the front, and the air inlet is arranged in the decorative cover. The air outlet blows from the top of the range hood body to the head area of ​​the cook, which has less interference with the oil fume suction area of ​​the range hood body. At the same time, the air guide plate of the range hood body can also separate the air outlet of the fan module from the oil fume suction area of ​​the range hood body so that the two do not interfere with each other. At the same time, when the oil fume escaping from the range hood escapes upward and approaches the face of the cook, the air curtain blown out by the air outlet of the fan module can also effectively prevent the oil fume from hitting the face. Due to the position arrangement of the air inlet and the air outlet, the air inlet area and the oil fume of the fan module are divided by the decorative cover. The negative pressure of the airflow generated at the air inlet causes the airflow to enter the decorative cover through the two sides of the range hood body and the top of the decorative cover, and is sucked into the air inlet in the decorative cover, ensuring that the cool air delivered to the cook is clean and pollution-free. While the fan module cools down the cook during cooking, it can also prevent the smell of the range hood body and food from being brought to the cook through the airflow.

[0011] In an optional embodiment, the fan module is located at the front end of the range hood body.

[0012] Beneficial effect: The fan module is located at the front end of the range hood body, which can move the air outlet closer to the front, thus preventing the air outlet from being blocked by the range hood body.

[0014] Beneficial effect: The air guide plate is rotatably connected to the air outlet and can be used to adjust the air outlet direction so that the air outlet can form an air curtain blowing towards the cook to accommodate cooks of different heights.

[0015] In an optional embodiment, the rotation angle α of the air guide plate satisfies 15°≤α≤85°.

[0016] Beneficial effect: The rotation angle of the air guide plate is between 15° and 85°, so that the air outlet of the fan module can adapt to cooks with a height of 155 cm to 185 cm.

[0017] In an optional embodiment, the fan module includes:

[0018] The front cover is provided with an air outlet grille;

[0019] The air duct assembly is connected to the rear side of the front cover, the air outlet is arranged in front of the air duct assembly and corresponds to the air outlet grille; the air guide plate is protruded with an adjustment part, and the adjustment part is movably arranged in the air outlet grille.

[0020] Beneficial effects: the air outlet grille can protect the air duct component and ensure smooth air outlet; the adjustment part is movably arranged at the air outlet grille, which makes it convenient for the cook to adjust the angle of the air guide plate by applying force to the adjustment part.

[0021] In an optional embodiment, the fan module is detachably connected to the range hood body via fasteners.

[0022] Beneficial effect: The fan module is detachably connected to the range hood body via fasteners, making it easy to disassemble and maintain the fan module.

[0023] In an optional embodiment, at least two connecting protrusions are provided at the bottom of the rear cover of the fan module, and at least two of the connecting protrusions are spaced apart along the length direction of the fan module. A first connecting hole is provided on the connecting protrusion, and at least two second connecting holes are correspondingly provided on the top of the range hood body, and the fasteners are detachably connected to the first connecting hole and the second connecting hole in sequence.

[0024] Beneficial Effects: The provision of the connecting protrusions not only facilitates the connection between the fan module and the range hood body, but also simplifies the structure of the fan module and fasteners, reducing the space occupied by the fan module and fasteners and facilitating their connection. Providing at least two connecting protrusions, spaced apart along the length of the fan module, provides a relatively stable fixed connection to the fan module, preventing localized stress concentration in the fan module.

[0025] In an optional embodiment, the fan module includes:

[0026] The front cover is provided with an air outlet grille;

[0027] An air duct assembly is connected to the rear side of the front cover, and the air outlet is arranged in front of the air duct assembly and corresponds to the air outlet grille;
