Description

Technical Field

[0001] The present invention relates to the field of ventilation, and in particular to a kitchen air conditioning system based on electrocoagulation technology. Background Art

[0002] Indoor cooking also suffers from a lack of ventilation, which primarily prevents the timely removal of cooking fumes and heat. Therefore, achieving efficient air conditioning in cooking areas, such as kitchens, is an urgent issue.

[0003] Traditional ventilation methods generally use a compressor to act on the entire working area to create negative pressure. This has a serious lag when the source of oil smoke is small, and the process of turning cooking into a negative pressure state will further spread the oil smoke. At the same time, because traditional ventilation methods only use compressors to extract oil smoke from the working area, they cannot effectively regulate the temperature of the working area. Obviously, this method no longer meets the needs of diversified production and life in modern society. Summary of the Invention

[0004] One of the purposes of the present invention is to solve the problem of timely extraction of polluted gases when they are generated in the working area, and the second purpose is to timely adjust the temperature of the working area. Therefore, a kitchen air conditioning system and kitchen appliances based on electrocoagulation technology are provided.

[0005] A kitchen air conditioning system based on electrocoagulation technology adopts the following technical solutions:

[0006] A kitchen air conditioning system based on electrocoagulation technology, the air conditioning system comprising:

[0007] Air intake components, exhaust components and controllers,

[0008] The air inlet assembly includes an air inlet duct and an air inlet fan. An ionization needle, a first deflection device, and a partition are sequentially arranged in the air inlet duct along the direction of air movement. The partition extends to the air outlet of the air inlet duct.

[0009] The exhaust assembly includes an exhaust duct and an exhaust fan, wherein a charging device and a second deflection device are sequentially provided in the exhaust duct along the direction of air movement;

[0010] The first deflection device and the second deflection device each include electrode plates disposed on opposite sides of the air inlet duct and the air exhaust duct respectively;

[0011] The controller includes:

[0012] The detection module comprises at least one first concentration detector for detecting the first concentration of the charged particles in the air at the air inlet of the exhaust duct, and at least one second concentration detector for detecting the second concentration of the charged particles in the air at the air outlet of the exhaust duct.

[0013] The judgment module is configured to acquire the first concentration and the second concentration, and send a first instruction to the execution module to increase the working voltage of the second deflection device when the first concentration is greater than the second concentration and the second concentration exists.

[0014] By using the above technical solution, the air inlet machine passes air into the air inlet duct, and the air is charged with positive and negative charges by the ionizing needle to obtain two kinds of charged particles, which are deflected by the first deflection device, and then are shunted by the partition plate into air mainly charged with positive charges and air mainly charged with negative charges.

[0015] The air charged with positive charges and the air charged with negative charges are simultaneously passed into the kitchen, and first, the oil droplets are adsorbed according to the principle of electrostatic adsorption. At the same time, the particles with opposite electric properties that have adsorbed the oil droplets attract each other to form larger particle groups. Under the action of the exhaust fan of the exhaust assembly, the particle groups enter the exhaust duct, are deflected by the charging device and the second deflection device, and are enriched in the exhaust duct, thereby reducing the difficulty of oil fume absorption in the kitchen and improving the effect and efficiency of oil fume absorption.

[0016] Preferably, the ionizing needle is arranged at the axis of the exhaust duct.

[0017] So that the charged particles are uniformly distributed.

[0018] Preferably, the air inlet duct and the exhaust duct are respectively provided with a grounding wire or an insulating material on the outer wall.

[0019] Preferably, the partition plate is made of an insulating material.

[0020] To avoid the mutual attraction of the particles charged with positive and negative charges in the duct.

[0021] Preferably, the electric field direction of the second deflection device is arranged to enable the particle groups passing through the charging device to deflect downward.

[0022] The oil droplets are enriched at the bottom of the exhaust duct, which is convenient for later cleaning and maintenance.

[0023] The greater the working voltage of the second deflection device is, the greater the deflection angle of the particle groups passing through the second deflection device is. When the first concentration is greater than the second concentration, the judgment module sends a first instruction to the execution module to adjust the deflection angle of the particle groups in real time, so that the particle groups are concentrated in the enrichment area in the exhaust duct.

[0024] Preferably, when the second concentration disappears, the judgment module box execution module sends a sixth instruction to restore the working voltage of the second deflection device before being adjusted by the execution module.

[0025] After the second concentration disappears, the judgment module realizes the pressure reduction of the second deflection device, which can reduce the energy consumption in the cooking process.

[0026] Furthermore, a collecting plate is provided on the inner bottom surface of the exhaust duct;

[0027] The detection module further comprises at least one third particle detector for detecting the actual total amount of charged particles on the collection plate;

[0028] The judgment module is used to obtain the actual total amount of charged particles. When the first concentration is greater than the second concentration and the actual total amount of charged particles on the collecting plate per unit time is less than the set value of the theoretical total amount of charged particles entering the exhaust duct, the judgment module sends a second instruction to the execution module to increase the operating voltage on the second deflection device and / or reduce the output power of the exhaust fan.

[0029] By comparing the actual amount of particles collected on the collection plate with the theoretical amount of charged particles collected per unit time, the deflection angle of the particle cluster can be adjusted to ensure that the particle cluster is enriched on the collection plate as much as possible, which is convenient for the subsequent collection of oil droplets and maintenance of the inside of the pipeline.

[0030] Preferably, the set value is 95% of the total amount of theoretically charged particles.

[0031] Preferably, when the first concentration is greater than 1.0 mg / m 3 , the output power of the exhaust fan cannot be reduced.

[0032] Furthermore, the collecting plate has a collecting channel at the center, and the collecting channel is provided with a guide groove radiating outward along the collecting plate, and the guide groove has a tendency to deepen in the direction pointing to the collecting channel. A collecting bottle for collecting oil droplets in the guide groove is provided at the bottom of the collecting channel, and a sealing ring is provided between the collecting bottle and the collecting channel.

[0033] The guide groove can ensure that the oil droplets on the collection plate can gather at the center of the collection plate, so that the collected oil droplets can flow out from the channel; the concave center of the collection plate can to a certain extent prevent the oil droplets from splashing due to vibration during the operation of the exhaust fan; the sealing ring ensures the sealing between the collection bottle and the collection channel, facilitates the collection of oil droplets and effectively prevents the leakage of oil droplets.

[0034] Furthermore, the detection module further includes a fourth switch detector for detecting the switch state of the cooker.

[0035] Further, the exhaust duct is provided with at least two air outlets respectively arranged on two sides of the partition plate, a driving device is arranged outside the exhaust duct, a movable plate matched with the air outlets is arranged on the driving device, the movable plate abuts against the air outlets, and the movable plate has at least a first position completely closing the air outlets and a second position completely opening the air outlets.

[0036] The judgment module is configured to acquire the on-off state of the stove, and send a third instruction to the execution module when the working state of the stove changes.

[0037] Further, the third instruction comprises:

[0038] When the stove changes from off to on, the ionization needle, the first deflection device, the driving device, the air inlet fan and the air outlet fan are sequentially powered on, and the movable plate is changed from the first position to the second position.

[0039] When the stove changes from on to off, the air inlet fan and the air outlet fan are delayed to be turned off, and then the ionization needle, the first deflection device and the driving device are sequentially powered off, and the movable plate is changed from the second position to the first position.

[0040] The fourth switch detector detects the on-off state of the stove, and controls the ionization needle, the first deflection device, the driving device, the air inlet fan and the air outlet fan in linkage after detecting that the working state of the stove changes, thereby improving the control efficiency; during the off process, the air outlet fan and the air inlet fan are delayed to be turned off, so that the residual oil fume can be more completely absorbed, and the cleaning effect is improved.

[0041] Further, the detection module further comprises at least one fifth temperature detector and at least one sixth temperature detector, the fifth temperature detector is configured to detect the temperature around the stove, and the sixth temperature detector is configured to detect the room temperature.

[0042] The judgment module is configured to acquire the temperature around the stove and the room temperature, and send a fourth instruction to the execution module to increase the output power of the air inlet fan and / or the air outlet fan when the temperature around the stove is higher than the room temperature.

[0043] When the temperature around the stove is higher than the room temperature, the judgment module sends a fourth instruction to the execution module to increase the output power of the air inlet fan and / or the air outlet fan to strengthen the air flow in the kitchen, take away the temperature in the cooking process, and finally achieve the purpose of cooling.

[0044] Further, the stove is further provided with a buzzer.

[0045] The judgment module is used to obtain the temperature around the stove and the room temperature. When the temperature around the stove does not drop to the room temperature within a unit time, the judgment module sends a fifth instruction to the execution module to drive the buzzer to alarm.

[0046] Alarm will be issued when the temperature is too high to avoid potential safety hazards.

[0047] In summary, this application has at least one of the following beneficial effects:

[0048] 1. Positively charged air and negatively charged air are introduced into the kitchen at the same time. They first adsorb oil droplets based on the principle of electrostatic adsorption. At the same time, due to the mutual attraction between positive and negative charges, the particles with opposite electrical properties that adsorbed the oil droplets attract each other to form a larger particle cluster. Under the action of the exhaust fan of the exhaust component, the particles enter the exhaust duct. After being deflected by the charging device and the second deflection device, they are enriched in the exhaust duct, reducing the difficulty of absorbing oil fume in the kitchen and improving the effect and efficiency of oil fume absorption.

[0049] 2. When the temperature around the stove is higher than the room temperature, the determination module sends a fourth instruction to the execution module to increase the output power of the air intake fan and / or the exhaust fan to increase the air flow in the kitchen, remove the heat generated during cooking, and ultimately cool the kitchen environment;

[0050] 3. The guide groove can ensure that the oil droplets on the collection plate can be collected at the center of the collection plate, which can facilitate the collected oil droplets to flow out from the channel; the concave center of the collection plate can to a certain extent prevent the oil droplets from splashing due to vibration during the operation of the exhaust fan; the sealing ring ensures the sealing between the collection bottle and the collection channel, which is convenient for the collection of oil droplets and effectively prevents oil droplets from leaking, making it easier to collect oil and maintain the interior of the pipeline in the future;

[0051] 4. The buzzer serves as an early warning, which can warn of abnormal system conditions in advance, effectively reducing safety hazards during the cooking process. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Kitchen 3 is equipped with a stove 30. When stove 30 is in operation, it generates oil smoke. At the same time, the positively and negatively charged airflow entering kitchen 3 and the oil droplets in the oil smoke are attracted to each other by electrostatic attraction, forming oil droplets with positive and negative charges. The oil droplets with different charges are attracted to each other due to the different charges, forming larger particle clusters. At this time, the positive and negative charges of the particle clusters cancel each other out, and the particles are then transported into exhaust duct 20 along the direction of air flow.

[0063] The air exhaust assembly 2 comprises an air exhaust duct 20, which is provided with an electric charging device 22, a second deflection device 23, a collection plate 24 and an air exhaust fan 21 in sequence along the air flow direction. The particle clusters are charged again when passing through the electric charging device 22. The particle clusters charged again pass through the second deflection device 23 and collide with the collection plate 24, and are finally enriched on the collection plate 24.

[0064] It should be noted that the air inlet duct 10 and the partition are made of insulating material, and the air exhaust duct 20 can be made of insulating material or be provided with a grounding wire (not shown in the figure) on the collection plate 24.

[0065] In combination Figure 1 and with reference to Figure 2 , the first deflection device 13 comprises two polar plates oppositely arranged on the inner side wall of the air inlet duct 10, and the two polar plates are oppositely charged to generate a uniform electric field.

[0066] The ionizing needle 12 is arranged at the center of the air inlet duct 10 to uniformly charge the particles with positive and negative charges. The partition 14 is parallel to the polar plates of the first deflection device 13 and is arranged along the symmetry axis of the cross section of the air inlet duct 10 and extends to the air outlet 15 of the air inlet duct 10.

[0067] The air outlet 15 is provided with at least two air outlets, which are respectively arranged on the two sides of the partition 14 to uniformly pass the airflows with different positive and negative charges into the kitchen 3.

The movable plate 17 is tightly arranged with the air inlet duct 10 and can slide with the air inlet duct 10 through the driving device 16. The movable plate 17 has at least a first position which completely closes all the air outlets 15 and a second position which completely opens all the air outlets 15.

[0069] In combination Figure 1 and with reference to Figure 3 , the second deflection device 23 comprises two polar plates oppositely arranged on the inner side wall of the air inlet duct 10, and the two polar plates are oppositely charged to generate a uniform electric field.

[0070] The collection plate 24 is arranged on the bottom wall of the air exhaust duct 20. The collection plate 24 is provided with a collection channel 25 at the center thereof. The collection channel 25 is provided with flow guide grooves 27 which are radially arranged outside the collection plate 24 and have a deepening trend in the direction pointing to the collection channel 25. The collection channel 25 is connected to the outside of the air exhaust duct 20. The collection channel 25 is provided with a collection bottle 28, and a sealing ring (not shown in the figure) is arranged between the collection bottle 28 and the collection channel 25.

[0071] It should be noted that the direction of the electric field between the second deflection device 23 is arranged to deflect the charged particle clusters downwardly.

[0072] In combinationFigure 1 And refer to Figure 4 The kitchen 3 is provided with a stove 30, which will generate oil smoke during cooking. Figure 2 At the same time, the positively and negatively charged airflows entering the kitchen 3 and the oil droplets in the oil smoke are attracted to each other under the action of electrostatic adsorption and become oil droplets with positive and negative charges respectively. At this time, the oil droplets with different charges attract each other according to the different charges to form larger particle clusters. At this time, the positive and negative charges of the particle clusters cancel each other out, and under the action of the exhaust fan 21, they enter the exhaust duct 20 along the direction of air movement.

[0073] refer to Figure 5 The controller 4 includes a detection module 5 for obtaining environmental information and converting it into a signal, a judgment module 6 for obtaining the signal, making a judgment and outputting a result, and an execution module 7 for obtaining the result and adjusting each electrical device.

[0074] Combine Figure 5 And refer to Figure 2 , the air inlet fan 11, the ionization needle 12, the first deflection device 13 and the driving device 16 are electrically connected to the execution module 7 respectively;

[0075] Combine Figure 5 And refer to Figure 3 The detection module 5 includes a first concentration detector 51 for detecting a first concentration of charged particles in the air at the air inlet of the exhaust duct 20, a second concentration detector 52 for detecting a second concentration of charged particles in the air at the air outlet of the exhaust duct 20, and a third particle detector 53 for detecting the actual total amount of charged particles on the collection plate 24;

[0076] The charging device 22 , the second deflecting device 23 and the exhaust fan 21 are electrically connected to the actuators respectively.

[0077] Combine Figure 5 And refer to Figure 4 The detection module 5 includes a fourth switch detector 54 for detecting the switch state of the cooker 30, a plurality of fifth temperature detectors 55 for detecting the ambient temperature of the cooker 30, and a sixth temperature detector 56 for detecting the room temperature. The fifth temperature detectors 55 are arranged close to the cooker 30 and away from the cooker 30.

[0078] The buzzer 31 is electrically connected to the actuator.

[0079] The overall operation process is now described with reference to the accompanying drawings:

[0081] When the cooker 30 is turned off, the air inlet fan 11 and the exhaust fan 21 are turned off after a delay, the ionization needle 12 is deenergized in sequence, the first deflection device 13 is deenergized, and the driving device 16 changes the movable plate 17 from the second position to the first position.

[0082] At this time, the third instruction is executed when the cooker 30 is turned from off to on.

[0083] refer to Figure 1 、 3 5. After the cooker 30 is turned on and the system is operating stably, the first concentration detector 51 and the second concentration detector 52 continuously detect the first concentration and the second concentration, and send the detected concentrations to the judgment module 6. When the first concentration is greater than the second concentration and is within the second concentration, the judgment module 6 sends a first instruction to increase the operating voltage of the second deflection device 23 to the execution module 7;

[0084] When the first concentration is reached and the second concentration disappears, the judging module 6 sends a sixth instruction to the executing module 7 to restore the working voltage of the second deflecting device 23 before being adjusted by the executing module 7;

[0085] The third sensor periodically detects the total amount of charged particles on the collecting plate 24. When the first concentration is greater than the second concentration and the actual total amount of charged particles on the collecting plate 24 per unit time is less than the set value of the theoretical total amount of charged particles entering the exhaust duct 20, the judgment module 6 sends a second instruction to the execution module 7 to increase the operating voltage of the second deflection device 23 and / or reduce the output power of the exhaust fan 21. It should be noted that the first concentration is greater than 1.0 mg / m 3 , the second instruction will not reduce the output power of the exhaust fan 21.

[0086] refer to Figure 1 、 4 5. After the cooker 30 is turned on and the system is operating stably, the fifth temperature detector 55 and the sixth temperature detector 56 respectively detect the temperature around the cooker 30 and the room temperature in real time. When the temperature around the cooker 30 is higher than the room temperature, the determination module 6 sends a fourth instruction to the execution module 7 to increase the output power of the air intake fan 11 and / or the exhaust fan 21 to increase the air flow in the kitchen 3.

[0087] When the temperature around the cooker 30 does not drop to the room temperature within a unit time, the judging module 6 sends a fifth instruction to the executing module 7 to drive the buzzer 31 to sound an alarm.

[0088] refer to Figure 1 、 2 4, 5. When cooking is finished and the cooker 30 is turned off, the fourth detector detects a change in the on / off state of the cooker 30.

[0090] At this time, the third instruction for switching the cooker 30 from on to off is executed.
