Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to a disposable oil collection and safety filtering range hood and a range hood. Background Art

[0002] The current range hood filtering systems generally combine front-end condensation filtering and centrifugal fan filtering. The overall filtering effect is not good, and about 10% of the grease is still discharged into the atmosphere, and there are some drawbacks. For example, the front-end condensation filtering is generally a mesh plate structure, and the range hood is easily blocked by grease after long-term use, resulting in a decrease in the smoking effect of the range hood, or even no smoking at all. And it is very troublesome to disassemble and clean the filtering hood with this mesh plate structure; at the same time, ordinary consumers are quite resistant to the cleaning work of the range hood, and it often needs to be cleaned by professionals, which brings an increase in the use cost. Moreover, it is easy to catch fire when cooking in the kitchen. Once a fire breaks out in the kitchen, effective help cannot be provided in the first time, which has deficiencies.

[0003] In addition, due to the serious current air quality problems, the emission of household cooking fume particles is also one of the pollution sources of PM2.5. Therefore, increasing the filtering effect of cooking fume particles can also effectively reduce the pollution of household cooking fume to the air. However, most of the current range hoods do not consider this problem. A small number of range hoods have added filtering devices at the air outlet end (rear end). However, due to the large wind pressure and fast flow rate at the rear end, most of the particles are discharged into the atmosphere before they can be filtered, resulting in an unsatisfactory filtering effect. At the same time, the replacement and maintenance of the filtering device installed at the rear end are relatively complicated and require professional personnel for maintenance. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a disposable oil collection and safety filtering range hood and a range hood.

[0007] A range hood fireproof cloth, the range hood fireproof cloth is provided with third collection holes, the third collection holes are matched with at least one group of collection holes of the first collection holes or the second collection holes, the range hood fireproof cloth is embedded and clamped in at least one smoking surface of the first range hood and the second range hood, and a shielding cloth is folded on the range hood fireproof cloth close to the smoking surface of the first range hood or the second range hood for urgently extinguishing a kitchen fire when it occurs.

[0008] According to the disposable oil - collecting and safety - filtering oil fume hood of the embodiments of the present invention, the first oil fume hood and the second oil fume hood with an internal hollow chamber structure facilitate the collection of oil fume. After collecting enough oil fume, the first oil fume hood and the second oil fume hood can be removed and discarded, which is convenient for one - time use and replacement. Compared with the existing metal mesh hood, the cost is lower, and at the same time, the cumbersome cleaning is avoided, which is suitable for most ordinary consumers. By embedding fire - proof cloth on the oil - smoking surfaces of the first oil fume hood and the second oil fume hood, the safety of the disposable oil - collecting and safety - filtering oil fume hood can be improved. When encountering an open fire suddenly, just tear off the fire - proof cloth and put down the shielding cloth to cover the third collection hole, then the oil pan and the open fire can be completely covered, achieving the effect of emergency fire - extinguishing and greatly improving the safety of using fire in the kitchen.
