Technical Field
[0001] The utility model relates to the technical field of kitchen smoke exhaust equipment, in particular to a high-efficiency oil smoke exhaust system for an integrated kitchen. Background Art
[0002] Due to the dietary habits in my country, most dishes need to be stir-fried when cooking. When stir-frying, the oil will produce a lot of fumes at high temperatures, accompanied by a pungent smell. These fumes will damage the respiratory system and have a strong irritation to the nose, eyes, and mucous membranes. The integrated kitchen is an integrated structure of cabinets, kitchen utensils, and kitchen appliances, which is popular among people. When people cook dishes in the integrated kitchen, in order to ensure the air quality in the kitchen and reduce the damage of cooking fumes to people's health, the method currently adopted by people is to install a range hood, install it above the stove, and use the exhaust fan to extract the exhaust gas from the stove and the fumes generated during cooking.
[0003] At present, when using range hoods to extract cooking fumes, the following problems often exist: first, the amount of fumes generated during the cooking process is extremely unstable, with the characteristics of fluctuating and randomness. As a result, when the amount of fumes generated is large, some of the fumes cannot be extracted in time, diffuse into the kitchen, and reduce the air environment in the kitchen; secondly, in order to achieve a better fume extraction effect, the range hood is often operated at the maximum suction power, and the amount of fumes is mostly less than the maximum estimated value, which leads to energy waste; thirdly, the number of stoves is often more than one, mostly two or more, and these stoves are not used at the same time in many cases, only some of them are used, and when extracting fumes, the range hood generates the same suction above each stove, resulting in a waste of suction above the stoves that are not used, and insufficient suction above the stoves that are used, causing some fumes to escape and poor fume extraction effect. Therefore, it is an objective need to develop an efficient fume extraction system for the overall kitchen that can accurately exhaust smoke, save energy, and have good fume extraction effect. Utility Model Content
[0004] The utility model aims to provide an efficient oil fume extraction system for an integrated kitchen which can accurately exhaust smoke, save energy and has a good oil fume extraction effect.
[0005] The purpose of the utility model is achieved in this way, including a stove and a plurality of stoves installed on the stove, a plurality of stove cores are installed on the stove, a range hood is arranged above the stove, the range hood includes a connected casing and a smoke collecting hood, a fan is correspondingly arranged in the casing above each stove core, two adjacent fans are separated by a partition, a temperature sensor and a photoelectric smoke sensor are installed on the smoke collecting hood above each stove core, a ring groove is arranged on the stove around each stove core, an air inlet is arranged at the bottom of the ring groove, an annular sealing cover is arranged on the top of the ring groove, and a plurality of air outlets are evenly distributed on the circumference of the sealing cover.
[0006] Furthermore, the air outlets are arranged in multiple circles from the outside to the inside, and the air outlets in two adjacent circles are arranged alternately.
[0007] Furthermore, the angle between the air outlet direction of the air outlet and the upper surface of the stove is α, and α is 70° to 90°.
[0008] Furthermore, the sealing cover is embedded in a groove on the surface of the stove, and an annular sealing gasket is provided between the inner side of the sealing cover and the stove, and between the outer side of the sealing cover and the stove.
[0009] Furthermore, an annular dirt collecting groove is arranged in the annular groove below the air outlet, and a cushion block is arranged at the bottom of the dirt collecting groove.
[0010] Furthermore, the cross-sectional area of the air outlet gradually decreases in the direction from the air inlet end to the air outlet end.
[0011] Furthermore, a spiral guide plate is provided in the air outlet.
[0012] When cooking is performed, fresh air enters the annular groove from the air inlet and is then ejected upward from the air outlet. The wind ejected from all the air outlets forms an annular wind curtain, which wraps all the oil smoke inside to prevent the oil smoke from spreading to the surroundings. Finally, the oil smoke is exhausted under the action of the range hood. In the above process, the temperature sensor monitors the oil temperature in the cooking pot on the stove core. According to the characteristic that the higher the oil temperature is, the greater the oil smoke is. When it is detected that the oil temperature is rising, the exhaust power of the fan is increased to meet the oil smoke extraction requirement. At the same time, the air intake of the air inlet is increased to prevent the oil smoke from passing through the wind curtain too much and causing kitchen air pollution. On the contrary, when it is detected that the oil temperature is lowered, the exhaust power of the fan is reduced to meet the oil smoke extraction requirement. At the same time, the air intake of the air inlet is appropriately reduced to prevent the oil smoke from passing through the wind curtain. In addition, a photoelectric smoke sensor is also provided in the system, which directly monitors the oil smoke. The temperature sensor and the photoelectric smoke sensor are combined. When the amount of oil smoke is large, the system's oil smoke extraction force is increased. On the contrary, when the amount of oil smoke is small, the system's oil smoke extraction force is reduced. This can adapt to the characteristics of extremely unstable, fluctuating and random oil smoke in the cooking process. The oil smoke generated in the cooking process can be discharged in time to prevent the spread of oil smoke in the kitchen and maintain the kitchen. Air environment; secondly, compared with the traditional oil fume extraction process, the range hood often operates at the maximum suction power. The system determines the oil fume suction power according to the amount of oil fume, and does not need to operate at the maximum suction power. Its suction power can meet the requirements of real-time oil fume extraction, which can avoid the waste of electric energy and reduce the electricity cost of residents, and can also reduce the operating power and operating load of the system, thereby extending the service life of the system; in addition, multiple fans and multiple ring grooves are set in the system.

DETAILED DESCRIPTION
[0017] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the present invention belong to the protection scope of the present invention.
[0018] like Figures 1 to 3 As shown, the utility model comprises a stove 1 and a plurality of stoves 2 mounted on the stove 1, a plurality of stove cores 3 are mounted on the stove 2, the stove 1 is arranged on a cabinet, the stove 2 is mounted on the stove 1, and the stove cores 3 are mounted on the stove 2. If the stove 2 is a natural gas stove, the stove cores 3 are used to spray natural gas for combustion and support the pots. A range hood 4 is arranged above the stove 2, and the range hood 4 includes a connected casing 5 and a smoke collecting hood 6, and each casing 5 above the stove core 3 is correspondingly provided with a A fan 7 is provided, and two adjacent fans 7 are separated by a partition 8. A temperature sensor 9 and a photoelectric smoke sensor 10 are installed on the smoke collecting hood 6 above each stove core 3. The temperature sensor 9 and the photoelectric smoke sensor 10 are both existing detection instruments. A ring groove 11 is provided on the stove 2 around each stove core 3, and an air inlet 12 is provided at the bottom of the ring groove 11. An annular sealing cover 13 is provided on the top of the ring groove 11, and a plurality of air outlets 14 are evenly distributed on the circumference of the sealing cover 13.
[0019] When cooking, the utility model allows fresh air to enter the annular groove 11 from the air inlet 12, and then be ejected upward from the air outlet 14. The wind ejected from all the air outlets 14 forms an annular wind curtain, which wraps all the oil smoke inside it to prevent the oil smoke from spreading to the surroundings. Finally, the oil smoke is discharged under the action of the range hood 4. In the above process, the temperature sensor 9 monitors the oil temperature in the cooking pot on the stove core 3. According to the characteristic that the higher the oil temperature, the greater the oil smoke, when it is detected that the oil temperature rises, the suction power of the fan 7 is increased to meet the oil smoke suction requirements, and the air intake of the air inlet 12 is increased to prevent excessive oil smoke from passing through the wind curtain and causing kitchen air pollution. On the contrary, when it is detected that the oil temperature drops, the suction power of the fan 7 is reduced to meet the oil smoke suction requirements, and the air intake of the air inlet 12 is appropriately reduced to prevent the oil smoke from passing through the air curtain. The system is provided with a photoelectric smoke sensor 10, which directly monitors the oil smoke. The temperature sensor 9 and the photoelectric smoke sensor 10 are combined. When the amount of oil smoke is large, the system's suction force on the oil smoke is increased. On the contrary, when the amount of oil smoke is small, the system's suction force on the oil smoke is reduced. This can adapt to the extremely unstable, fluctuating and random characteristics of the amount of oil smoke in the cooking process, and can timely discharge the oil smoke generated in the cooking process to prevent the spread of oil smoke in the kitchen and maintain the kitchen. air environment; secondly, compared with the traditional oil fume extraction process, the range hood 4 is often operated at the maximum suction power. The system determines the oil fume suction power according to the amount of oil fume, and does not need to operate at the maximum suction power. Its suction power can meet the requirements of real-time oil fume extraction, which can avoid the waste of electric energy and reduce the electricity cost of residents, and can also reduce the operating power and operating load of the system, thereby extending the service life of the system; in addition, a plurality of fans 7 and a plurality of ring grooves 11 are arranged in the system, and the fans 7, the ring grooves 11, the temperature The temperature sensor 9 and the photoelectric smoke sensor 10 correspond to each stove core 3 one by one, so that smoke extraction, temperature monitoring and oil smoke monitoring are all targeted, and can accurately monitor the amount of oil smoke generated at each stove core 3 position, and appropriately adjust the oil smoke suction power according to the detected oil smoke situation, thereby avoiding the problem that the current range hood 4 generates the same suction force above each stove core 3, thereby generating a waste of suction force and energy, and can also ensure that the oil smoke can be fully sucked, prevent the oil smoke from escaping, and have a better oil smoke extraction effect.
[0020] The air outlets 14 on the sealing cover 13 are arranged in multiple circles from the outside to the inside, and the air outlets 14 of two adjacent circles are arranged in a staggered manner. Each circle of air outlets 14 ejects airflow to form an air curtain, and multiple circles of air outlets 14 form multiple air curtains. The diffusion of oil smoke must pass through the above multiple air curtains in sequence, which increases the difficulty of oil smoke diffusion and reduces the possibility of oil smoke diffusion, ensuring that the oil smoke can be better extracted and exhausted. At the same time, the two adjacent circles of air outlets 14 are arranged in a staggered manner. This is because there are sometimes certain holes in the air curtain between the two adjacent air outlets 14, and oil smoke may escape from these holes. The staggered arrangement of the two adjacent circles of air outlets 14 can play a role of mutual compensation. In this way, the combination of use can improve the sealing of the air curtain and the blocking effect of oil smoke, and effectively prevent the escape of oil smoke.
[0021] The angle α between the air outlet direction of the air outlet 14 and the upper surface of the stove 2 is 70° to 90°. The wind can blow vertically upward or be inclined at a certain angle to one side of the center of the stove core 3. The specific angle can be determined according to parameters such as the size of the stove core 3, the size of the pots used, and the distance between the range hood 4 and the stove 1 to ensure that the wind curtain can block the spread of oil smoke and the oil smoke can be fully exhausted by the range hood 4.
[0022] The sealing cover 13 is embedded in the groove on the surface of the stove 2, and an annular sealing gasket 15 is provided between the inner side of the sealing cover 13 and the stove 2, and between the outer side of the sealing cover 13 and the stove 2. In actual use, it is found that there is often a gap between the inner side of the sealing cover 13 and the stove 2, and between the outer side of the sealing cover 13 and the stove 2. During operation, part of the wind will be ejected from the above gap, thereby reducing the air volume of the air outlet 14 and reducing the blocking effect of the wind curtain on oil smoke. In order to avoid the above problem, the annular sealing gasket 15 is provided to effectively fill the above gap so that the wind can be ejected from the air outlet 14.
[0023] An annular dirt collecting groove 16 is arranged in the annular groove 11 below the air outlet 14, and a pad 17 is arranged at the bottom of the dirt collecting groove 16. The utility model is used for the oil fume extraction of the whole kitchen. Considering that the annular groove 11 is arranged on the stove 2, during the cooking process, there will always be a small amount of food, soup, grease, etc. falling on the stove 2 due to operational errors and other reasons. At this time, some soup or grease may flow into the annular groove 11 along the air outlet 14, which is inconvenient to clean. Over time, it may form a pollution source and attract various insects. At the same time, it may also block the annular groove 11 and the air outlet 14, affecting the normal operation of the system. In order to solve these problems, a dirt collecting groove 16 is arranged. When soup and grease enter the annular groove 11 along the air outlet 14, they will automatically fall into the dirt collecting groove 16. It only needs to take out the dirt collecting groove 16 regularly for cleaning, so as to ensure the environment of the stove 1.
[0024] The cross-sectional area of the air outlet 14 gradually decreases from the air inlet end to the air outlet end. When the wind passes through the air outlet 14, the effective flow area is continuously reduced, which forces the wind speed to increase. When the wind blows out from the air outlet 14, it has a faster flow rate and thus a greater impact force, forming a more stable wind curtain and having a better effect of blocking oil smoke.
[0025] A spiral guide plate 18 is provided in the air outlet 14. When the wind passes through the spiral guide plate 18, a cyclone can be formed. In this way, the oil smoke is located in the wind curtain formed by a number of small cyclones. By utilizing the strong attraction of the cyclone, on the one hand, it can further prevent the oil smoke from passing through the wind curtain to cause pollution. On the other hand, it can also generate suction on the air outside the wind curtain, so that a weak negative pressure area is formed around the wind curtain. The air outside the wind curtain has a tendency to move toward the wind curtain, thereby preventing the spread of oil smoke.
