Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology
[0002] Currently, most traditional range hoods on the market use a fixed smoke extraction section design, meaning that the smoke extraction section is usually installed above the stove and maintained at a fixed height. However, different cooking methods produce different amounts of oil fumes during daily cooking. For example, high-temperature cooking methods such as stir-frying and deep-frying produce a lot of oil fumes, while steaming and stewing produce relatively less. Because the smoke extraction section of traditional range hoods is in a fixed position, their smoke extraction effect is acceptable when there is little oil fume. However, when the amount of oil fume is large, some of the oil fume may not be absorbed in time during its diffusion process, causing the oil fume to escape into the kitchen environment, affecting air quality and potentially harming human health. Utility Model Content
[0003] The purpose of this utility model is to provide a range hood that addresses the problem that the position of the smoke extraction section of existing range hoods is fixed, making it impossible for users to adjust the position of the smoke extraction section according to the changes in the amount of oil fumes generated by different cooking methods, resulting in limited smoke extraction effect and easy dispersion of oil fumes into the kitchen environment.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A range hood includes a first body and a second body. A fan is installed inside the second body. The first body is located below the second body. A telescopic part is located below the first body. One end of the telescopic part is connected to the first body and the other end is connected to a smoke extraction part. The telescopic part is used to drive the smoke extraction part to move up and down.
[0006] A flexible connector is provided between the first body and the second body. The flexible connector has a hollow structure, with one end connected to the first body and the other end connected to the second body.
[0007] In this application, the first unit is fixedly connected to the wall, and the second unit is located inside the kitchen ceiling and fixedly connected to the ceiling.
[0008] This utility model relates to a range hood. By incorporating a telescopic section between the first body and the smoke extraction unit, the user can adjust the distance between the smoke extraction unit and the stovetop according to different cooking methods. This is particularly beneficial when stir-frying dishes, as the telescopic section brings the smoke extraction unit closer to the source of the fumes, drawing them in before they spread widely. This improves smoke extraction efficiency, reduces the spread of fumes, and ensures user safety. Furthermore, the second body houses a fan that provides airflow, and the second body is connected to the first body with the smoke extraction unit via a flexible connector. This flexible connector cushions vibrations generated during prolonged operation, reducing the damage caused by fan vibration and improving the stability and user comfort of the device.
[0009] As a preferred embodiment of the present invention, the telescopic part includes a first sleeve, which is connected to the first body. A second sleeve is slidably connected inside the first sleeve. The end of the second sleeve away from the first body is connected to the smoking part. A lifting cylinder is provided on the second sleeve, with one end of the lifting cylinder connected to the second sleeve and the other end connected to the first body.
[0010] This invention achieves stable drive control of the telescopic part by setting a lifting cylinder on the second sleeve, with one end connected to the second sleeve and the other end connected to the first body, enabling the smoke extraction unit to rise and fall smoothly. This structural design allows the smoke extraction unit to be closer to the source of oil fumes, reducing the diffusion of oil fumes and improving the cleanliness of the kitchen environment.
[0011] As a preferred embodiment of this utility model, the smoking part is provided with smoke inlets on both sides, and the smoke inlets are arranged horizontally on the smoking part.
[0012] As a preferred embodiment of this utility model, the smoking part is provided with hinges on both sides, and the smoking part is connected to a baffle through the hinges. The hinges are located above the smoke inlet, and when the hinges are opened, they are used to guide the oil fumes into the smoke inlet.
[0013] By installing hinges on both sides of the smoke extraction section and connecting baffles through these hinges, the baffles can be opened and closed as needed, thereby optimizing the collection of cooking fumes. When the range hood is working, the baffles unfold, guiding the cooking fumes towards the smoke inlet, improving the efficiency of fume capture and preventing the fumes from spreading into the kitchen environment.
[0014] As a preferred embodiment of this utility model, the first body is provided with a driving component, which is used to drive the hinge to move the baffle to work.
[0015] As a preferred embodiment of this utility model, an oil collection box is provided at the bottom of the smoking part.
[0016] By installing an oil collection box at the bottom of the smoke extraction unit, the oil absorbed during cooking can be effectively collected, preventing oil from accumulating on the inner wall of the smoke extraction unit, thereby reducing cleaning difficulty and maintaining the long-term efficient operation of the equipment.
[0017] As a preferred embodiment of this utility model, the maximum extension distance h of the telescopic part is 350mm-450mm.
[0018] As a preferred embodiment of the present invention, the fan is disposed at the connection between the second body and the flexible connector, with one side of the fan facing the second body and the other side facing the flexible connector.
[0019] By placing the fan at the connection point between the second body and the flexible connector, with one side facing the second body and the other facing the flexible connector, the airflow path for fume extraction is optimized, improving extraction efficiency. This design allows the fan to directly power the inhaled fumes, reducing flow resistance during transport, preventing backflow or turbulence, and improving smoke extraction performance.
[0020] As a preferred embodiment of this utility model, the flexible connector body is a corrugated pipe.
[0021] As a preferred embodiment of this utility model, the top of the second body is provided with a lifting lug, which is used to fix the second body in the ceiling.
[0022] By incorporating lifting lugs on the top of the second unit, it can be easily secured within the ceiling, improving installation stability and adaptability. This design allows for concealed installation of the range hood, effectively saving kitchen space, enhancing overall aesthetics, and avoiding the problem of traditional wall-mounted or countertop range hoods occupying space above the stove.
[0023] As a preferred embodiment of this utility model, the bottom of the side wall of the smoking part is provided with an installation groove, and an oil receiving box is provided in the installation groove, and the oil receiving box is fixed to the smoking part by bolts.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0025] 1. This utility model relates to a range hood. By incorporating a telescopic section between the first body and the smoke extraction section, the user can adjust the distance between the smoke extraction section and the stovetop according to different cooking methods. This is especially beneficial when stir-frying dishes, as the telescopic section brings the smoke extraction section closer to the source of the fumes, drawing them in before they spread widely. This improves smoke extraction efficiency, reduces the spread of fumes, and ensures user safety. Furthermore, the second body contains a fan that provides airflow, and the second body is connected to the first body with the smoke extraction section via a flexible connector. This flexible connector cushions the vibrations generated by the fan during prolonged operation, reducing the damage caused by fan vibration and improving the stability and user comfort of the device.

[0039] Example 1
[0040] In this application, the first body 1 is fixedly connected to the kitchen wall and hidden in the kitchen cabinet, and the second body 2 is located in the kitchen ceiling and fixedly connected to the ceiling.
[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 5 The range hood shown includes a second body 2 with a fan 21 installed. The second body 2 is located inside the kitchen ceiling during subsequent range hood installation. A first body 1 is located below the second body 2, and a smoke extraction section 3 is provided on the first body 1. The user extracts the fumes through the smoke extraction section 3. The second body 2 and the first body 1 are connected by a flexible connector 5. The user can adjust the distance between the second body 2 and the first body 1 through the flexible connector 5. When the fan 21 in the second body 2 operates for a long time, the fan 21 is prone to vibration. If the second body 2 and the first body 1 are connected by a traditional rigid connection, the vibration of the fan 21 is not attenuated during the transmission to the first body 1, resulting in greater noise and affecting the user experience. In this application, the flexible connector 5 can buffer the vibration generated by the fan 21, thereby reducing the damage caused by the vibration of the fan 21 to the entire device and improving the stability and comfort of the device.
[0042] The first body 1 and the smoking part 3 are connected by a telescopic part 4. The telescopic part 4 includes a first sleeve 41 that communicates with the first body 1.
