An energy-saving kitchen ventilation system

Abstract

This utility model relates to the technical field of kitchen ventilation systems and discloses an energy-saving kitchen ventilation system, including a range hood. A ventilation duct is connected to the top of the range hood. Both the head and tail of the ventilation duct are equipped with air pressure display components. Each air pressure display component includes a cylinder. A cylinder is fixedly sleeved on the outside of the ventilation duct, and a first piston is movably sleeved inside the cylinder. A moving rod is fixedly installed on one side of the first piston. This energy-saving kitchen ventilation system, by having air pressure display components at both the head and tail of the ventilation duct, generates air pressure when airflow passes through the head and tail of the ventilation duct. This pressure compresses the first piston, causing the moving rod to extend out of the cylinder. By observing the length of the extended moving rod at the head and tail of the ventilation duct, the air pressure at the head and tail of the ventilation duct can be determined, allowing the user to understand whether there is a blockage in the middle of the ventilation duct and to address it promptly.

Description

Technical Field

[0001] This utility model relates to the technical field of kitchen ventilation systems, specifically an energy-saving kitchen ventilation system. Background Technology

[0002] Existing energy-saving kitchen ventilation systems utilize intelligent sensor control: infrared / temperature / humidity sensors monitor the stove's usage status in real time and automatically adjust the airflow (e.g., reducing to the lowest ventilation mode when no one is using it). Load response: The exhaust volume is dynamically adjusted according to cooking intensity (e.g., high speed during stir-frying, low speed during steaming). Energy saving effect: 30-50% energy saving compared to constant airflow systems. Energy-saving kitchen ventilation systems use EC fans (brushless DC motors): 20-30% more efficient than traditional AC fans, with reduced power consumption. Inverter control: The fan speed is adjusted in real time according to duct pressure, avoiding constant power waste.

[0003] In existing energy-saving kitchen ventilation systems, after prolonged use, some debris can accumulate inside the ventilation ducts, eventually causing blockages. Because the ducts are opaque, people cannot promptly detect blockages, thus affecting ventilation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving kitchen ventilation system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving kitchen ventilation system, including a range hood, with a ventilation duct connected to the top of the range hood. Both the head and tail of the ventilation duct are equipped with air pressure display components. The air pressure display component includes a cylinder. A cylinder is fixedly sleeved on the outer side of the ventilation duct. A first piston is movably sleeved inside the inner cavity of the cylinder. A moving rod is fixedly installed on one side of the first piston. A spring is movably sleeved on the outer side of the moving rod. The two ends of the spring are respectively fixedly installed on the first piston and the cylinder. A grid is provided at the bottom of the range hood.

[0006] As a further improvement of this utility model, the air pressure display component also includes a scale, and the scale is provided on the outer side of the moving rod.

[0007] As a further improvement of this utility model, the range hood is provided with a cleaning assembly, which includes a connecting rod, an air cylinder, a second piston, a gas adapter cylinder, a third piston, a connecting plate, and a cleaning sleeve. The connecting rod is fixedly installed on the other side of the first piston. The air cylinder is fixedly installed on the top of the inner cavity of the range hood. The second piston is movably sleeved in the inner cavity of the air cylinder. One side of the second piston is connected to one end of the connecting rod. The gas adapter cylinder is fixedly installed on one side of the air cylinder. The third piston is movably sleeved in the inner cavity of the gas adapter cylinder. One end of the third piston is connected to the connecting plate. The cleaning sleeve is movably sleeved on the outer side of the grille. The connecting plate is connected to the cleaning sleeve.

[0008] As a further improvement of this utility model, the grid bar is provided with two rows of cleaning sleeves, each row of cleaning sleeves is connected to each other, and the two rows of cleaning sleeves are connected by a horizontal plate.

[0009] As a further improvement of this utility model, the gas adapter tube is U-shaped, with the gas cylinder and the third piston respectively located at both ends of the gas adapter tube.

[0010] As a further improvement of this utility model, the diameter of the gas cylinder is larger than the diameter of the gas adapter cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This energy-saving kitchen ventilation system has air pressure display components at both the head and tail of the ventilation duct. When airflow passes through the head and tail of the ventilation duct, air pressure is generated, which squeezes the first piston and drives the moving rod to extend out of the cylinder. By observing the length of the moving rod extending out of the head and tail of the ventilation duct, the air pressure at the head and tail of the ventilation duct can be obtained, so that the user can know whether there is a blockage in the middle of the ventilation duct and deal with it in time.

[0013] 2. This energy-saving kitchen ventilation system connects the first piston to the second piston via a connecting rod. When the first piston moves, it can drive the second piston inside the air cylinder, thereby pushing the gas inside the air cylinder into the gas transfer cylinder. This controls the movement of the third piston and the cleaning sleeve. The movement of the cleaning sleeve facilitates the removal of impurities adhering to the grid bars.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides an energy-saving kitchen ventilation system, including a range hood 1. A ventilation duct 2 is connected to the top of the range hood 1. A pressure display component 3 is provided at both the head and tail of the ventilation duct 2. The pressure display component 3 includes a cylinder 31. The cylinder 31 is fixedly sleeved on the outside of the ventilation duct 2. A first piston 32 is movably sleeved in the inner cavity of the cylinder 31. A moving rod 33 is fixedly installed on one side of the first piston 32. A spring 34 is movably sleeved on the outside of the moving rod 33. The two ends of the spring 34 are respectively fixedly installed on the first piston 32 and the cylinder 31. A grid 4 is provided at the bottom of the range hood 1. The ventilation duct 2 is equipped with air pressure display components 3 at both the head and tail. When airflow passes through the head and tail of the ventilation duct 2, air pressure is generated, which squeezes the first piston 32 and drives the moving rod 33 to extend out of the cylinder 31. By observing the length of the moving rod 33 extending out of the head and tail of the ventilation duct 2, the air pressure at the head and tail of the ventilation duct 2 can be obtained, so that the user can know whether there is a blockage in the middle of the ventilation duct 2 and deal with it in time.

[0022] The air pressure display component 3 also includes a scale 35, which is provided on the outer side of the moving rod 33. The scale 35 allows the user to easily observe the extended length of the moving rod 33 and to compare the extended lengths of the two moving rods 33.

[0023] The range hood 1 is equipped with a cleaning component 5, which includes a connecting rod 51, an air cylinder 52, a second piston 53, a gas adapter cylinder 54, a third piston 55, a connecting plate 56, and a cleaning sleeve 57. The connecting rod 51 is fixedly installed on the other side of the first piston 32. The air cylinder 52 is fixedly installed on the top of the inner cavity of the range hood 1. The second piston 53 is movably sleeved in the inner cavity of the air cylinder 52. One side of the second piston 53 is connected to one end of the connecting rod 51. The gas adapter cylinder 54 is fixedly installed on one side of the air cylinder 52. The third piston 55 is movably sleeved in the inner cavity of the gas adapter cylinder 54. One end of the third piston 55 is connected to the connecting plate 56. The cleaning sleeve 57 is movably sleeved on the outer side of the grille 4. The connecting plate 56 is connected to the cleaning sleeve 57. The first piston 32 is connected to the second piston 53 via the connecting rod 51. When the first piston 32 moves, it can drive the second piston 53 inside the air cylinder 52, thereby pushing the gas inside the air cylinder 52 into the gas transfer cylinder 54, thereby controlling the movement of the third piston 55 and the cleaning sleeve 57. By using the movement of the cleaning sleeve 57, it is easy to clean the impurities adhering to the grid bar 4.

[0024] The grid bar 4 is provided with two rows of cleaning sleeves 57, and each row of cleaning sleeves 57 is connected to each other. The two rows of cleaning sleeves 57 are connected by a horizontal plate 58. By setting two rows of cleaning sleeves 57, the cleaning speed is improved.

[0025] The gas transfer cylinder 54 is U-shaped, with the gas cylinder 52 and the third piston 55 located at opposite ends. The shape of the gas transfer cylinder 54 facilitates the movement of the third piston 55 in the opposite direction when the second piston 53 moves in one direction, thus controlling the movement of the cleaning sleeve 57.

[0026] The diameter of the air cylinder 52 is larger than the diameter of the gas transfer cylinder 54. By utilizing the diameter difference between the air cylinder 52 and the gas transfer cylinder 54, the second piston 53 can move a small distance to drive the third piston 55 to move a large distance, thus achieving comprehensive cleaning of the grid bars 4.

[0027] Working principle: When using this device, the ventilation duct 2 is equipped with air pressure display components 3 at both the head and tail. When the airflow passes through the head and tail of the ventilation duct 2, air pressure is generated, which squeezes the first piston 32 and drives the moving rod 33 to extend out of the cylinder 31. By observing the length of the moving rod 33 extending from the head and tail of the ventilation duct 2, and since the moving rod 33 is equipped with a scale 35, it can be determined whether the air pressure at the head and tail of the ventilation duct 2 is the same or whether there is a large deviation. This allows the user to understand whether there is a blockage in the middle of the ventilation duct 2 and to deal with it in a timely manner.

[0028] When this system is in use, the moving rod 33 moves, and when the first piston 32 moves, it can drive the second piston 53 inside the air cylinder 52, thereby pushing the gas in the air cylinder 52 into the gas transfer cylinder 54. Due to the diameter difference between the air cylinder 52 and the gas transfer cylinder 54, the third piston 55 and the cleaning sleeve 57 are controlled to move a large range. By using the movement of the cleaning sleeve 57, the impurities adhering to the grid bar 4 are cleaned away.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
