Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood and a use method thereof. Background Art

[0002] At present, traditional range hoods on the market generally adopt a fixed suction section design, that is, their suction sections are usually installed above the stove and maintained at a fixed height. However, in daily cooking, different cooking methods will produce different amounts of oil smoke. For example, high-temperature cooking methods such as stir-frying and frying will produce a lot of oil smoke, while methods such as steaming and stewing will produce relatively less oil smoke. Since the suction section of traditional range hoods is fixed in position, when there is less oil smoke, its suction effect is still acceptable, but when the amount of oil smoke is large, some of the oil smoke may not be absorbed in time during the diffusion process, causing the oil smoke to escape into the kitchen environment, affecting the air quality and possibly causing harm to human health. Summary of the invention

[0003] The purpose of the present invention is to provide a range hood and a method of using the same in order to address the problem in the prior art that the position of the suction chamber of a range hood is fixed, and the user cannot adjust the position of the suction chamber according to the change in the amount of oil smoke generated by different cooking methods, resulting in limited suction effect and oil smoke easily escaping into the kitchen environment.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A range hood, comprising a first body and a second body, wherein a fan is arranged in the second body, the first body is arranged below the second body, a telescopic part is arranged below the first body, one end of the telescopic part is connected to the first body, and the other end is connected to a smoking part, and the telescopic part is used to drive the smoking part to perform lifting movement;

[0006] A flexible connector is provided between the first body and the second body. The flexible connector is a hollow structure. One end of the flexible connector is connected to the first body, and the other end is connected to the second body.

[0007] In the present application, the first body is fixedly connected to the wall, the second body is located in the kitchen ceiling and fixedly connected to the ceiling, and the side wall of the second body is provided with a flue connected to the outdoor environment.

[0008] The present invention is a range hood, in which a telescopic part is arranged between a first body and a suction chamber, and the telescopic part drives the suction chamber to perform lifting and lowering movements, so that a user can adaptively adjust the distance between the suction chamber and the stove according to different cooking methods. In particular, when making dishes such as stir-frying, the suction chamber is adjusted to a closer distance from the stove through the telescopic part, so that the suction chamber is closer to the source of oil smoke, thereby sucking the oil smoke into the suction chamber before the oil smoke begins to spread over a large area, thereby improving the cleaning efficiency of the oil smoke, reducing the external expansion of the oil smoke, and ensuring the physical safety of the user; in the present application, a fan providing wind power is arranged in the second body, and the second body is connected to the first body with the suction chamber by a flexible connector, so that when the fan works for a long time, vibration is likely to occur, and the flexible connector of the present application can buffer the vibration generated by the fan, thereby reducing the harm caused by the vibration of the fan to the entire equipment, and improving the stability of the equipment and the comfort of use.

[0009] As a preferred embodiment of the present invention, the telescopic part includes a first sleeve, the first sleeve is connected to the first body, a second sleeve is slidably connected inside the first sleeve, one end of the second sleeve away from the first body is connected to the smoking part, and a lifting cylinder is provided on the second sleeve, one end of the lifting cylinder is connected to the second sleeve, and the other end is connected to the first body.

[0010] The present invention realizes stable driving control of the telescopic part by arranging a lifting cylinder on the second sleeve, and connecting one end of the cylinder to the second sleeve and the other end to the first body, so that the smoking part can be lifted and lowered smoothly. This structural design enables the smoking part to be closer to the oil fume source, reduces the diffusion of oil fume, and improves the cleanliness of the kitchen environment.

[0011] As a preferred solution of the present invention, smoke inlets are provided on both sides of the smoking section, and the smoke inlets are transversely arranged on the smoking section.

[0012] As a preferred solution of the present invention, hinges are provided on both sides of the smoking section, the smoking section 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 oil smoke into the smoke inlet.

[0013] By setting hinges on both sides of the smoke extraction section and connecting the baffles through the hinges, the baffles can be opened and closed as needed, thereby optimizing the collection effect of oil smoke. When the range hood is working, the baffles are unfolded to guide the oil smoke to the smoke inlet, improve the oil smoke capture efficiency, and prevent the oil smoke from spreading to the kitchen environment.

[0014] As a preferred solution of the present invention, a driving component is provided in the first body, and the driving component is used to drive the hinge to drive the baffle to work.

[0015] As a preferred solution of the present invention, an oil receiving box is provided at the bottom of the smoking portion.

[0017] As a preferred embodiment of the present invention, the maximum extension distance h of the telescopic portion is 350 mm-450 mm.

[0018] As a preferred solution of the present invention, the fan is arranged at the connection point 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 arranging the fan at the connection between the second body and the flexible connector, with one side facing the second body and the other side facing the flexible connector, the airflow path of the smoke is optimized and the suction efficiency is improved. This design enables the fan to directly provide power to the smoke, reduce the flow resistance of the smoke during the transportation process, avoid backflow or turbulence, and improve the smoke exhaust effect.

[0020] As a preferred solution of the present invention, the flexible connector body is a bellows.

[0021] As a preferred solution of the present invention, a lifting lug is provided on the top of the second body, and the lifting lug is used to fix the second body in the suspended ceiling.

[0022] By arranging a hanging ear on the top of the second body, it can be conveniently fixed in the ceiling, improving the stability and adaptability of the installation. This design enables the range hood to be installed in a hidden manner, effectively saving kitchen space and improving the overall aesthetics, while avoiding the problem of traditional wall-mounted or desktop range hoods occupying the space above the stove.

[0023] As a preferred solution of the present invention, a mounting groove is provided at the bottom of the side wall of the smoking section, an oil receiving box is provided in the mounting groove, and the oil receiving box is fixed to the smoking section by bolts.

[0028] The smoke extraction unit sucks the oil smoke and sequentially transmits the oil smoke to the first body, the flexible connecting member and the second body.

[0029] The present invention is a range hood, which adjusts the position of the suction portion by a telescopic portion so that the suction portion can be flexibly close to the source of oil smoke. Especially in cooking modes with a lot of oil smoke such as stir-frying, the suction portion is away from the first body and directly covers the oil smoke generating area, effectively reducing the diffusion of oil smoke and improving the extraction efficiency.

[0057] In one or more embodiments, the body of the flexible connector 5 is a bellows;

[0058] Optionally, the flexible connecting member 5 may also be a rubber tube.
