Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and more specifically to an energy-saving range hood. Background Technology

[0002] A range hood is a machine used to absorb kitchen fumes. It can effectively expel the fumes outdoors, keep the air inside the kitchen fresh, and maintain a good cooking environment.

[0003] Currently, most range hoods on the market have relatively fixed air inlet structures and sizes. When dealing with different amounts of cooking fumes, they simply rely on adjusting the power of the exhaust fan to adjust the ventilation effect. This results in poor functional adjustability, serious energy waste, and difficulty in meeting the needs of green and environmentally friendly practices.

[0004] In view of this, this utility model proposes an energy-saving range hood to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy-saving range hood to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an energy-saving range hood, including a casing, an air inlet hood fixedly installed at the bottom of the casing, an exhaust pipe fixedly installed on the inner wall of the casing, a centrifugal fan embedded in the outer wall of the exhaust pipe, and the impeller of the centrifugal fan extending into the interior of the exhaust pipe, a connecting pipe fixedly installed at the top of the casing, the connecting pipe being connected to the exhaust pipe, the outlet end of the connecting pipe being connected to an external exhaust pipe, a lower glass fixedly installed at the bottom of the air inlet hood, and an air inlet port reserved at the bottom of the air inlet hood, an opening and closing glass corresponding to the air inlet port being provided on the inner wall of the air inlet hood, the opening and closing glass being rotatably connected to the air inlet hood, and an air inlet opening and closing component for controlling the opening and closing glass to open inward or outward being provided on the inner wall of the air inlet hood corresponding to the opening and closing glass;

[0007] The air intake opening and closing assembly includes an electric push rod rotatably mounted on the inner rear wall of the air intake hood. The telescopic end of the electric push rod is rotatably connected to a connecting rod. The right end of the connecting rod is rotatably connected to the inner wall of the air intake hood. A limit guide rail is rotatably connected to the inner right wall of the air intake hood. An installation post is fixedly mounted on the upper side of the lower glass. The other end of the limit guide rail is fixed to the installation post. The end of the connecting rod away from the inner wall of the air intake hood is slidably connected to the inner wall of the limit guide rail.

[0008] Furthermore, a control panel is fixedly installed on the right side of the air intake shroud, and the control panel is electrically connected to an external power source via a wire.

[0009] As a further description of the above technical solution: By setting up a control panel, operators can control the energy-saving range hood through the control panel, such as adjusting the power of the centrifugal fan and controlling the opening and closing degree of the glass, making the range hood more flexible and convenient to use. At the same time, the setting of the control panel also improves the intelligence level of the range hood and meets the intelligent needs of modern kitchens for home appliances.

[0010] Furthermore, a mounting slot is provided on the left side of the chassis, and a hook is installed inside the mounting slot. The hook is fixed to the external wall by bolts.

[0011] As a further description of the above technical solution: by setting hooks and mounting slots, operators can easily hang the range hood on the kitchen wall without complicated installation steps, which improves the ease of installation of the range hood. At the same time, the setting of mounting slots and hooks also increases the stability of the range hood during installation, preventing the range hood from falling during use and ensuring the safety of operators.

[0012] Furthermore, the exhaust pipe is spiral-shaped, and the air inlet and outlet of the centrifugal fan are connected to the air inlet hood and the connecting pipe, respectively.

[0013] Furthermore, there are two mounting columns, which are located on the front and rear sides of the lower glass, respectively. A secondary mesh plate is fixedly installed between the adjacent surfaces of the two mounting columns and the upper surface of the lower glass. When the glass is opened inward, the airflow path inside the air inlet port corresponds to the position of the secondary mesh plate. A main mesh plate is fixedly installed horizontally between the inner right wall of the air inlet hood and the mounting columns. When the glass is opened outward, the airflow path inside the air inlet port corresponds to the position of the main mesh plate.

[0014] As a further description of the above technical solution: by setting up a secondary mesh plate and a main mesh plate, the oil fumes entering the air intake hood can be initially filtered, avoiding the situation where larger particles enter the air extraction pipe and damage the centrifugal fan, thus improving the service life of the range hood.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, this energy-saving range hood uses a centrifugal fan to generate negative pressure inside the extraction pipe at high speed. This allows external fumes to be drawn into the extraction pipe through the air inlet hood from the air inlet port, and then discharged to the external exhaust pipe through the connecting pipe, achieving the effect of smoke extraction. By setting an air inlet opening and closing component, the opening and closing operation of the glass can be adjusted according to actual usage needs. When a small amount of fumes needs to be absorbed, the glass can be controlled to open inward, allowing the fumes to enter the air inlet hood through the secondary mesh plate. The centrifugal fan maintains low power operation, which has the advantages of low power consumption and low noise. When a large amount of fumes needs to be absorbed quickly, the glass can be controlled to open outward, allowing the fumes to enter the air inlet hood through the main mesh plate and the secondary mesh plate. While reducing the power demand on the centrifugal fan, the smoke collection range is greatly increased, thereby allowing adjustment of the smoke absorption efficiency, avoiding energy waste, and making it more green and environmentally friendly.

[0017] 2. Compared with existing technologies, this energy-saving range hood features a control panel, allowing operators to control the hood, such as adjusting the centrifugal fan power and controlling the opening and closing of the glass, making it more flexible and convenient to use. The control panel also enhances the range hood's intelligence, meeting the modern kitchen's demand for smart appliances. Hooks and mounting slots allow for easy wall mounting on the kitchen surface without complicated procedures, improving ease of installation. These features also increase stability during installation, preventing the range hood from falling and ensuring operator safety. The secondary and main mesh panels provide preliminary filtration of fumes entering the air intake hood, preventing larger particles from damaging the centrifugal fan and extending the range hood's lifespan.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The energy-saving range hood involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 6 This utility model provides an energy-saving range hood, including a casing 1. A mounting slot 13 is provided on the left side of the casing 1. A hook 14 is installed inside the mounting slot 13. The hook 14 is fixed to the external wall by bolts.

[0027] By setting up hooks 14 and mounting slots 13, operators can easily hang the range hood on the kitchen wall without complicated installation steps, which improves the ease of installation. At the same time, the mounting slots 13 and hooks 14 also increase the stability of the range hood during installation, preventing it from falling during use and ensuring the safety of operators.

[0028] A control panel 12 is fixedly installed on the right side of the air intake shroud 2. The control panel 12 is electrically connected to an external power source via wires.

[0029] By setting up the control panel 12, operators can control the energy-saving range hood through the control panel 12, making the range hood more flexible and convenient to use. At the same time, the setting of the control panel 12 also improves the intelligence level of the range hood, meeting the intelligent needs of modern kitchens for home appliances.

[0030] An air intake hood 2 is fixedly installed at the bottom of the casing 1. An exhaust pipe 3 is fixedly installed on the inner wall of the casing 1. A centrifugal fan 4 is embedded in the outer wall of the exhaust pipe 3, and the impeller of the centrifugal fan 4 extends into the interior of the exhaust pipe 3. A connecting pipe 5 is fixedly installed at the top of the casing 1. The connecting pipe 5 is connected to the exhaust pipe 3. The outlet end of the connecting pipe 5 is connected to the external exhaust pipe. The exhaust pipe 3 is spiral-shaped. The air inlet end and the air outlet end of the centrifugal fan 4 are connected to the air intake hood 2 and the connecting pipe 5, respectively.

[0031] This energy-saving range hood uses a centrifugal fan 4 to rotate at high speed, creating negative pressure inside the extraction pipe 3. This allows external fumes to be drawn into the extraction pipe 3 from the air inlet port through the air inlet hood 2, and then discharged to the external exhaust pipe through the connecting pipe 5, thus achieving the effect of smoke removal.

[0032] The bottom of the air intake hood 2 is fixedly installed with a lower glass 6, and the bottom of the air intake hood 2 is reserved with an air inlet port. The inner wall of the air intake hood 2 is provided with an opening and closing glass 7 that is adapted to and blocks the air inlet port. The opening and closing glass 7 is rotatably connected to the air intake hood 2.

[0033] The inner wall of the air intake hood 2 is provided with an air intake opening and closing component that controls the opening and closing of the glass 7 to open inward or outward.

[0034] The air intake opening and closing assembly includes an electric push rod 8 rotatably mounted on the inner rear wall of the air intake hood 2. The telescopic end of the electric push rod 8 is rotatably connected to a connecting rod 9. The right end of the connecting rod 9 is rotatably connected to the inner wall of the air intake hood 2. A limit guide rail 10 is rotatably connected to the inner right wall of the air intake hood 2. An installation post 11 is fixedly mounted on the upper side of the lower glass 6. The other end of the limit guide rail 10 is fixed to the installation post 11. The end of the connecting rod 9 away from the inner wall of the air intake hood 2 is slidably connected to the inner wall of the limit guide rail 10.

[0035] By setting up an air intake opening and closing component, the opening and closing operation of the glass 7 can be performed according to actual usage needs. When a small amount of oil fume needs to be absorbed, the electric push rod 8 can be controlled to retract, causing the glass 7 to open inward. At this time, the oil fume enters the air intake hood 2, and the centrifugal fan 4 maintains low power operation, which has the advantages of low power consumption and low noise. When a large amount of oil fume needs to be absorbed quickly, the electric push rod 8 can be controlled to extend, causing the glass 7 to open outward. At this time, the oil fume enters the air intake hood 2. While reducing the power demand on the centrifugal fan 4, the smoke collection range is greatly increased, thereby realizing the adjustment of the oil fume absorption efficiency, avoiding energy waste, and making it more green and environmentally friendly.

[0036] There are two mounting columns 11, which are located on the front and rear sides of the lower glass 6 respectively. A secondary mesh plate 15 is fixedly installed between the adjacent surfaces of the two mounting columns 11 and the upper surface of the lower glass 6. When the glass 7 is opened inward, the airflow path inside the air inlet port corresponds to the position of the secondary mesh plate 15.

[0037] The main mesh plate 16 is fixedly installed horizontally between the inner right wall of the air intake hood 2 and the mounting column 11. When the opening and closing glass 7 is opened outward, the airflow path inside the air intake port corresponds to the position of the main mesh plate 16.

[0038] By setting up the secondary mesh plate 15 and the main mesh plate 16, the oil fumes entering the air intake hood 2 can be initially filtered, avoiding the situation where larger particles enter the exhaust pipe 3 and damage the centrifugal fan 4, thus improving the service life of the range hood.

[0039] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
