Description

A full-filter oil fume purifier

technical field

The utility model relates to a range hood, in particular to a fully-filtered range hood purifier.

Background technique

At present, the traditional range hoods used in every household and sold on the market are all centrifugal range hoods, that is, the airflow is "thrown out" radially through the centrifugal blades. In this way, the airflow has an impact in the volute, especially for the traditional cross-flow fan range hood, the airflow passes through the impeller and flows in the volute, and repeatedly impacts the impeller, flue or volute, so the airflow in the volute causes Loud noise. In addition, after the noise of the motor running and the vibration noise of the machine parts are superimposed, the total noise reaches more than 80 decibels, which is higher than the national standard of 68 decibels for the noise of range hoods in my country, so this will also seriously interfere with the normal operation of the user and the neighbors around the user. Live, bring inconvenience to people's life. In addition, in the cross-flow fan type range hood, since the air flow is forced to turn in the volute, the pressure head loss is relatively large, the efficiency is low, and the flow rate is small.

At the same time, the existing range hoods can be divided into top suction type and side suction type according to the types, and their shapes are the same. After long-term development, there has been no major improvement, so its appearance is difficult to give people a refreshing feeling. How to create a novel appearance structure has become an important factor for many manufacturers to enhance their market competitiveness. In addition, the main body of the existing volute is roughly in the shape of a "6", so when this kind of volute is suitable for a top suction range hood, the smoke outlet of the volute is generally set at a non-central position on the top of the range hood. As a result, the installation of the smoke exhaust pipe of the range hood is very troublesome, and it is difficult to assemble and use with equipment such as cabinets. However, when it is suitable for side suction range hoods, the suction port of the volute is installed at an angle, so that the range hood cannot directly act on the range hood when it is in use, resulting in a certain reduction in its smoking capacity.

In addition, in the existing range hoods, the range hoods all need an external exhaust pipe, and the oil fume drawn from the kitchen is discharged to the outside through the exhaust pipe. Therefore, the oil fumes that get rid of are mixed with a large amount of harmful gases such as oil stains, which seriously affect environmental sanitation. Therefore be necessary to make further improvement to existing range hood.

working principle

Air deflector: The air deflector in this case includes a fixed plate 121 and an oil collecting pan 122 installed in it. There are several air guiding pipes 123 evenly distributed on the periphery of the oil collecting pan 122. The air guiding pipes 123 are located between the fixed plate 121 and the oil collecting pan. The disks 122 are connected to the smoking port 4 of the fan module; wherein, the air inlet of the air guide pipe is waist-shaped, and the air outlet is round pipe-shaped, and the two are excessively connected by a connecting pipe. Therefore, the air inlet of the air guide pipe is larger than its air outlet, and the air guide pipe is set at a certain angle of inclination. Therefore, when the fan module generates negative pressure to absorb oil fume, the oil fume will enter the air inlet pan in a helical direction, and with the As the air duct narrows, the wind speed will be gradually increased, thereby increasing the air pressure of the air intake of the air guide, making it have a stronger smoking ability. In addition, the oil fume from multiple air guide pipes 123 gathers at the air inlet of the air guide module, so the oil fume entering the fan module gathers in a multi-rotary manner, causing the oil fumes to collide with each other and contact the air guide pipes, so that the oil can be released. The inside of the air duct is liquefied, which plays the first role of oil fume separation.

Fan module: In this case, the fan module is composed of hemispherical upper and lower volutes that are fastened to each other. The two volutes can be connected by screws, buckle connections and other connection structures to be fixed as a whole. In actual use, the whole fan module can be fixed inside the range hood body. When the range hood is working, the driving motor drives the smoking turbine to rotate rapidly, forming a negative pressure at the smoking port of the lower volute, and the oil fume is sucked from the middle of the suction turbine under the action of atmospheric pressure, and then discharged vertically outward. When the oil fume collides with the turbine, the grease in the oil fume is first attached to the turbine, which plays the second role of oil fume separation. Then, in the process of contacting the oil fume with the upper volute, it plays the third role of oil fume separation. When the oily fumes contact the first volute, the oily fume is discharged upwards from the air guide channel 9 formed between the insulating cover 8 and the upper volute 1 by the guidance of the inner surface of the volute and the restriction of the isolation cover. Finally, it is exhausted through the smoke outlet 3 provided on the top of the upper volute 1. The oil separated from the fan module will enter the oil collecting pan 122 for storage through the drainage hole at the bottom of the volute. If necessary, the oil collecting pan 122 only needs to be disassembled and cleaned.

Compared with the traditional "6" shaped volute turbine structure, this case adopts a unique spherical volute structure, coupled with the air guide channel formed by the isolation cover in the volute, so that the smoking port and exhaust port of the oil fume are at the same position. On the axis, so as to realize the effect of axial flow smoke exhaust. When this module is assembled with other range hoods, the smoke exhaust pipe can be located at the center of the range hood body, which is convenient for assembly and use with cabinets and the like.

What needs to be explained is that the turbofan is used as the power in this case, and compared with the traditional axial flow fan, it has the advantages of larger air suction volume and lower working noise. At the same time, the upper end surface of the smoking turbine 7 is provided with a connecting sleeve 72, and the cylindrical surface of the connecting sleeve 72 is axially provided with several stages of positioning buckles 73, and the boss 61 arranged on the main shaft of the driving motor is clamped on the positioning buckles. 73 internal fixation. When the user needs to disassemble the turbine for oil cleaning, he only needs to pull the turbine fan outwards forcefully to disengage the positioning buckle from the boss. After the cleaning is completed, as long as the inner surface of the connecting sleeve 72 is provided with a protruding coupling block 74, it is inserted into the coupling groove 62 provided on the motor shaft to realize the shaft connection, and the boss 61 is stuck on the positioning buckle 73 Internal fixation is enough, so that the turbo blade can be quickly disassembled and assembled without tools. Through a large number of experiments in this application, it is known that when the oil fume is separated from the oil fume by the air deflector and the fan module for many times, the oil pollution rate in the flue gas can reach 80%.

Filter module: In this case, the filter module is detachably installed on the air outlet of the fan module. Therefore, when the user adopts direct discharge, it is not necessary to use this filter module. Directly connect the exhaust pipe to the outdoors, or connect to the public flue. But in some developed and environmentally friendly countries, this kind of situation is not allowed. At the same time, the direct discharge type range hood is prone to smoke backflow, and the phenomenon that the smoke cannot be discharged normally when the outdoor wind pressure is too high. Aiming at this, this case is provided with filtering module. There are about 20% of oil and other harmful substances in the flue gas discharged from the fan module. Therefore, the filtering module in this case has the following layers and has the following functions:

The first layer: primary coarse filter screen 132; it can be made of materials such as non-woven glass fiber net, nano-carbon ball filter screen, and it is mainly used for filtering dust particles greater than or equal to microns.

The second layer: EVA sponge filter screen 133; because the sponge has excellent oil resistance and abrasion resistance, it can filter oil and further reduce the grease content in the flue gas.

The third layer: activated carbon filter screen 134; it can remove volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and pollutants in the air in the oil fume. At the same time, it also has the effect of deodorizing and deodorizing.

The fourth layer: formaldehyde removal filter screen 135; the filter screen is a metal mesh, the surface of which forms a porous metal oxide layer in situ and the porous metal oxide layer is loaded with metal active components Pt, Ru, Rh, Pd, Au or Ag or its oxides can catalyze the oxidation of formaldehyde pollutants into water and carbon dioxide when the range hood is running.

The fifth layer: HEPA filter screen 136; the filter screen filters particles with a diameter of 0.1-0.5 μm, and its removal efficiency for particles with a diameter of 0.3 microns (1/200 of the hair diameter) can reach more than 99.97%. Effectively filter smoke, dust and bacteria in the kitchen.

Based on the above, after the oil fume in this case is filtered by the air guide, the fan module and the oil fume separator of the filter module, the oil content in the exhausted gas can be removed to more than 99.9%, so it can be directly discharged indoors. Among them, in order to make the gas entering the filter screen more fully and evenly contact with each layer of filter screen, in this case, a conical air guide block 137 is arranged in the fixed cylinder 131, and the air guide block can guide the smoke entering the filter to the surroundings. The filtered oil fume is directly discharged from the exhaust port 138 on the cylindrical surface of the fixed cylinder 131, so as to prevent the gas from being directly discharged upwards and affecting the hygiene of the user's ceiling.

Therefore, compared with the traditional technology, the oil fume in this case is directly discharged into the indoor environment after multiple filtrations. While not affecting the indoor air quality, it avoids the need to arrange exhaust pipes for traditional range hoods, and avoids backflow or outdoor wind pressure. If it is too large, the range hood cannot open the check valve, which will affect the smoke exhaust effect. When the range hood is used in a non-cooking situation, it can also function as an air purifier to filter and purify the indoor air to ensure the cleanness of the user's indoor ambient air, so it can be widely used.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model.
