Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an integrated range hood for quick replacement of activated carbon filter elements. Background Technology

[0002] An integrated fume purifier is a device that integrates the functions of collecting and purifying kitchen fumes. It is mainly used in the catering industry, food processing sites, or home kitchens. The integrated fume purifier uses the fume collection hood or air intake at the front of the device to draw the fumes generated during cooking into the device through the negative pressure generated by the fan, and releases the purified gas outdoors to reduce air pollution.

[0003] In the purification module of an integrated fume purification machine, components such as filters, electrostatic fields, and activated carbon filters work together to achieve efficient purification of fumes. However, existing activated carbon filters generally adopt a block-shaped carbon block stacking structure. Their arrangement, which is closely attached to the inner wall of the equipment, results in a large number of carbon blocks being tightly distributed during filter replacement. This makes the removal process not only time-consuming and laborious but also prone to carbon powder scattering. In addition, when replacing the activated carbon filter, due to the large size and deep purification space of the integrated machine, operators need to stack a large number of carbon blocks in a limited space, which is not only labor-intensive but also time-consuming. As a result, the overall replacement efficiency of the activated carbon filter is low. Therefore, an integrated fume purification machine with a quick activated carbon filter replacement is proposed.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0032] Example 1

[0033] Reference Figures 1-4 The first embodiment of this utility model provides an integrated fume purification machine with quick-replaceable activated carbon filter element, which can quickly remove the activated carbon block from the purification hood and complete the replacement more quickly. It includes: an overall unit 100, a purification unit 200 and a support unit 300.

[0034] The overall unit 100 includes a smoke collection hood 101 and a flow guide hood 102 fixedly connected to the top of the smoke collection hood 101. A smoke collection module 103 is provided on the top of the smoke collection hood 101.

[0035] The purification unit 200 includes a purification hood 201 fixedly connected to the top of the smoke collection hood 101, a flow guide hood 102 fixedly connected to one side of the purification hood 201, a smoke extraction module 103 disposed on the top of the purification hood 201, a replacement port 202 opened on the side wall of the purification hood 201, and a sealing plate 203 fixed thereon by bolts, and a large number of activated carbon blocks 204 and a conveying section 205 for quick replacement of activated carbon blocks 204 are provided inside the purification hood 201.

[0036] The support unit 300 is installed on the top of the smoke collection hood 101. The support unit 300 is used to prevent the activated carbon block 204 from rubbing against the smoke collection hood 101 when the activated carbon block 204 is replaced.

[0037] Activated carbon block 204 blocks the connection between the flow guide hood 102 and the purification hood 201. The smoke extraction module 103 generates negative pressure at the top of the purification hood 201, causing the smoke collection hood 101 to collect oil fumes. The oil fumes are then introduced into the purification hood 201 through the flow guide hood 102, causing the oil fumes to be adsorbed and purified by the activated carbon block 204 inside the purification hood 201. Finally, the oil fumes are discharged through the smoke extraction module 103. The replacement port 202 on the side wall of the purification hood 201 is sealed by the sealing plate 203. When the activated carbon block 204 needs to be replaced, the sealing plate 203 is removed. Then, the saturated activated carbon block 204 is quickly moved out of the replacement port 202 through the conveying part 205. At the same time, the worker sends the new activated carbon block 204 into the designated position inside the purification hood 201 through the replacement port 202 via the conveying part 205 to complete the batch replacement. The purification hood 201 has space inside for installing components such as filters and electrostatic fields.

[0038] Therefore, workers can replace activated carbon blocks at the replacement port 202 without having to go deep into the purification hood 201, using the conveying unit 205 to do so in a time-saving, labor-saving, and efficient manner. During the replacement process, the supporting unit 300 supports the activated carbon block 204, keeping it isolated from the top of the fume hood 101, preventing carbon powder from falling into the fume hood 101 due to friction during handling or transportation, thus avoiding contamination of the top of the fume hood 101. After the replacement is completed, the sealing plate 203 is used to seal the replacement port 202.

[0039] Example 2

[0040] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, the smoking module 103 includes a smoke hood 103a fixedly connected to the top of the purification hood 201. A fan 103b is fixedly installed on the inner wall of the smoke hood 103a, and an exhaust pipe 103c is fixedly connected to the top of the smoke hood 103a.

[0041] The fan 103b drives the impeller to rotate through the built-in motor to generate negative pressure, forming airflow suction in the purification hood 201. The oil fumes enter the purification hood 201 through the fume collection hood 101 and the guide hood 102. Under the action of negative pressure, the fumes are purified by the activated carbon block 204. The purified gas is then discharged outdoors through the exhaust pipe 103c.

[0042] Example 3

[0043] Reference Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, the conveying unit 205 includes two drive rollers 205a rotatably connected to the inner wall of the purification hood 201. A servo motor 205b is fixedly installed on one side of the purification hood 201. The output end of the servo motor 205b rotatably passes through the purification hood 201 and is fixedly connected to one of the drive rollers 205a. A conveyor belt 205c is provided inside the purification hood 201. Activated carbon blocks 204 are distributed on the conveyor belt 205c. A ring of toothed blocks is provided at both ends of the two drive rollers 205a. A ring of protrusions that fit the drive rollers 205a is provided at both ends of the inner wall of the conveyor belt 205c. The protrusions of the conveyor belt 205c mesh with the toothed blocks of the drive rollers 205a. The two drive rollers 205a are used to drive the conveyor belt 205c for transmission.

[0044] The servo motor 205b drives the drive roller 205a to rotate, and the meshing of the toothed blocks at both ends of the drive roller 205a with the protrusions on the inner wall of the conveyor belt 205c drives the conveyor belt 205c to circulate. When the activated carbon block 204 needs to be replaced, the servo motor 205b rotates in the forward direction, causing the conveyor belt 205c to move the activated carbon block 204 along the inner wall of the purification hood 201, thereby discharging the activated carbon block 204 from the replacement port 202. The speed of the servo motor 205b can be controlled by an external controller so that the worker can take out the activated carbon block 204 in time. Then, the new activated carbon block 204 is placed equidistantly on the conveyor belt 205c, and the servo motor 205b rotates in the reverse direction to transport the activated carbon block 204 into the purification hood 201. The worker, along with the moving conveyor belt 205c, synchronously spreads the activated carbon block 204 on the conveyor belt 205c to complete the installation.

[0045] The conveying unit 205 also includes multiple support rollers 205d that are rotatably connected to the inner wall of the purification hood 201. Each support roller 205d is distributed in the inner ring of the conveyor belt 205c. The two ends of the support roller 205d are thin and the middle is thick. The support roller 205d does not contact the protrusions of the conveyor belt 205c.

[0046] The support roller 205d avoids contact with the protrusions of the conveyor belt 205c at both ends, and the support roller 205d simultaneously supports the conveyor belt 205c in the middle to prevent the activated carbon block 204 from shifting or sagging during the conveying process, so as to ensure the stable conveying of the activated carbon block 204.

[0047] In addition, an oil-absorbing cloth 206 is fitted on the outer surface of the conveyor belt 205c. One end of the oil-absorbing cloth 206 is attached to the surface of the conveyor belt 205c, and the other end of the oil-absorbing cloth 206 is attached to its own surface.

[0048] The oil-absorbing cloth 206 can be made of cotton or other materials. It can absorb residual oil and particulate matter in the fumes and help the activated carbon block 204 to improve the purification effect. In addition, the oil-absorbing cloth 206 can be disassembled and replaced regularly to avoid the long-term accumulation of oil stains affecting the transmission efficiency of the conveyor belt 205c, while reducing the internal cleaning cost of the equipment.

[0049] Example 4

[0050] Reference Figure 1 and Figure 4 This is the fourth embodiment of the present utility model. Unlike the previous embodiment, the supporting unit 300 includes multiple limiting rings 301 fixedly connected to the top of the smoke collection hood 101. Each limiting ring 301 has a support column 302 slidably provided on its inner ring. The top of the multiple support columns 302 is fixedly connected to a support plate 303.

[0051] The support plate 303 can be fixed to the top of the smoke hood 101 by the support column 302 and the limiting ring 301. When the activated carbon block 204 is replaced, the support plate 303 keeps the activated carbon block 204 connected to the conveyor belt 205c inside the purification hood 201, which facilitates manual or mechanical handling of the activated carbon block 204. The discharged activated carbon block 204 can fall directly onto the support plate 303 and then be removed to prevent carbon powder from falling onto the smoke hood 101 due to friction during handling or conveying. After replacement, the support plate 303 can be removed and the carbon powder and debris that fell onto the support plate 303 can be cleaned up.

[0052] Among them, a pair of baffles 304 are fixedly connected to the top of the support plate 303, and both sides of the two baffles 304 are smoothly transitioned.

[0053] When the activated carbon block 204 is placed on the support plate 303, the baffle 304 prevents it from slipping and falling off due to external impact or vibration during transportation, while the rounded edges prevent scratching the operator or abrading the activated carbon block 204.

[0054] In addition, multiple rotating rods 305 are rotatably connected between the opposing surfaces of the two baffles 304, and the multiple rotating rods 305 are distributed horizontally at equal intervals.

[0055] When the activated carbon block 204 is transferred from the support plate 303 to the conveyor belt 205c, the rotating rod 305 can rotate automatically with the contact friction force, converting sliding friction into rolling friction, greatly reducing the handling resistance, and the operator can complete the position adjustment with just a light push.

[0056] During use, after the fan 103b is started, the fume hood 101 collects the oil fumes and guides them into the purification hood 201 through the guide hood 102. The oil, particulate matter and odors in the hood are adsorbed and purified by the activated carbon block 204. The purified gas is then discharged outdoors through the exhaust pipe 103c. The purification hood 201 can be equipped with filters, electrostatic fields and other components, which together with the activated carbon block 204 improve the purification effect. When it is necessary to replace the saturated activated carbon block 204, the sealing plate 203 is removed, and then the support plate 303 is fixed to the top of the fume hood 101 through the support column 302 and the limiting ring 301. Then, the servo motor 205b of the conveying unit 205 is started, so that the two drive rollers 205a drive the conveyor belt 205c to move, and the saturated activated carbon block 204 is quickly moved out from the replacement port 202.

[0057] The discharged activated carbon blocks 204 can fall directly onto the support plate 303 and then be removed. After discharge, the oil-absorbing cloth 206 can be disassembled and replaced. When the new oil-absorbing cloth 206 is replaced, the new activated carbon blocks 204 are placed at equal intervals on the conveyor belt 205c. Then, the servo motor 205b rotates in the opposite direction to transport the new activated carbon blocks 204 to the designated position inside the purification hood 201 to complete the batch replacement. After replacement, the replacement port 202 is sealed with the sealing plate 203. Then, the support plate 303 is removed, and the carbon powder and debris that fell on the support plate 303 are cleaned up.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
