Description

Technical Field

[0001] The utility model relates to the technical field of component spraying, in particular to a range hood which is easy to clean. Background Art

[0002] Range hoods are devices used to remove fumes, smoke and odors generated in the kitchen. During the cooking process, cooking food will produce fumes. If there is no effective exhaust equipment, fumes and smoke will accumulate indoors, which will not only affect the air quality, but may also leave odors and grease in the home that are difficult to remove. Range hoods effectively purify indoor air by forcibly extracting fumes and odors from the air, keeping the kitchen air fresh and tidy.

[0003] A traditional easy-to-clean range hood usually consists of several key components. The first is the body shell, which is usually made of materials such as stainless steel, glass or plastic, and is designed to be smooth for cleaning and to avoid oil stains. The second is the oil fume collection component, including an oil net or filter that is easy to disassemble and clean to capture grease particles in the oil fume, and an oil cup or oil box that collects grease, which is easy to clean regularly to avoid accumulation. The fan and exhaust duct are responsible for exhausting the oil fume. The fan design needs to be high temperature resistant, quiet and efficient, and the exhaust duct should reduce resistance and dust accumulation to facilitate cleaning and maintenance. The control panel and electrical components include control switches, wind speed and lighting functions, and the design should be simple, easy to operate, safe and durable.

[0004] However, in the traditional design of the range hood, the filter structure is difficult to quickly disassemble and clean, which may lead to a variety of problems. First, the filter that is difficult to clean thoroughly will accumulate a lot of grease and dirt, affecting its filtration efficiency, resulting in the inability to effectively purify the oil fume, increasing the risk of air pollution. Secondly, the filter that has not been cleaned for a long time is likely to become a breeding ground for bacteria and mold, which may affect the health of family members. In addition, incomplete cleaning of the filter will also affect the service life of the range hood, because the accumulated grease may cause damage to mechanical parts or reduce operating efficiency. Therefore, a range hood that is easy to clean is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a range hood that is easy to clean, aiming to improve the problem in the prior art that the filter cannot be quickly disassembled, resulting in excessive accumulation of internal oil smoke and causing bacterial growth.

One end of the first fixing column 13 is fixed to the side wall of the filter screen 7, and the inside of the filter screen 7 is provided with a hole, and the first fixing column 13 is firmly fixed inside the filter screen 7. This design allows the user to quickly disassemble the filter screen 7, which is convenient for cleaning and maintenance of the range hood.

[0033] Reference Figure 1 and Figure 3 An oil storage tank 6 is slidably connected to the bottom of the fuselage 3, a fixed block 5 is fixedly connected to the bottom of the fuselage 3, a filter screen 7 is arranged inside the fuselage 3, a hole is opened inside the filter screen 7, a second fixing column 16 is threadedly connected inside the fixing block 5, a fixing ring 15 is fixedly connected to the outer wall of the second fixing column 16, a handle 14 is fixedly connected inside the second fixing column 16, a second hollow column 17 is arranged on the outer wall of the second fixing column 16, a spring 18 is arranged at one end of the second fixing column 16, a conical column 22 is fixedly connected to one end of the spring 18, a conical column 22 is arranged on the outer wall of the conical column 22, a connecting column 21 is fixedly connected inside the second hollow column 17, a rolling ball 20 is arranged on the outer wall of the conical column 22, and the outer wall of the rolling ball 20 is arranged inside the fixing ring 19.

[0034] Specifically, by rotating the handle 14, the force of the handle 14 drives the second fixed column 16 to rotate, and the rotation of the second fixed column 16 causes the spring 18 to contract. The tightening of the spring 18 causes the conical column 22 to push forward and move, and the movement of the conical column 22 causes the ball 20 on the outer wall to move accordingly. The outer wall of the ball 20 moves so that it is pressed against the groove inside the fixed collar 19. The rotation of the second fixed column 16 inside the fixed block 5 stably supports the oil storage tank 6, ensuring that it can effectively support and store the grease collected by the range hood.

[0035] Reference Figure 1A display component is provided on the side wall of the fuselage 3, and the display component is used to select a mode function. The display component includes a display screen 2, and the side wall of the display screen 2 is fixedly connected to the side wall of the fuselage 3. A first hollow column 1 is fixedly connected to the top of the fuselage 3, and a suction fan is provided inside the first hollow column 1.

[0036] Specifically, when using a range hood that is easy to clean, the oil smoke is first introduced into the interior of the machine body 3 through the exhaust fan inside the first hollow column 1, and filtered through the filter 7, thereby achieving the effect of effectively purifying the air and absorbing the oil smoke, ensuring the freshness of the kitchen air.

[0037] Working principle: When using a range hood that is easy to clean, first, the exhaust fan inside the first hollow column 1 is used to suck the oil smoke and the filter 7 into the interior of the machine body 3, thereby achieving the effect of sucking out the oil smoke. Then, by pulling the handle 8, the handle 8 drives the connecting plate 9 to rotate, and the force of the connecting plate 9 drives the half gear 10 to rotate. The force of the half gear 10 drives the rack 11 meshed with it to move, and the rack 11 moves inside the hollow block 4, and the movement of the rack 11 drives the clamping block 12 to move. The movement of the clamping block 12 causes the internal hole to clamp the first fixed column 13, and one end of the first fixed column 13 is fixed to the side wall of the filter 7, and the inside of the filter 7 A hole is opened, and the first fixing column 13 is fixed inside the filter screen 7, so that the filter screen 7 can be quickly disassembled. Next, by turning the handle 14, the force of the handle 14 drives the second fixing column 16 to rotate, and the rotation of the second fixing column 16 drives the spring 18 to contract. After the spring 18 is tightened, the conical column 22 is pushed forward to move. The force of the spring 18 drives the conical column 22 to move. At the same time, the movement of the conical column 22 causes the rolling ball 20 on the outer wall to move. The movement of the rolling ball 20 causes its outer wall to rest against the groove inside the fixing ring 19. Then the second fixing column 16 rotates inside the fixing block 5, so as to achieve the effect of stably supporting the oil storage tank 6.
