Description

Multifunctional smoke hood

Technical Field

The utility model relates to the technical field of smoke hood equipment, in particular to a multifunctional smoke hood.

Background

The fume hood is mainly applied to the equipment used by the collaborative fume hood installed in areas such as restaurants, kitchens and the like, and mainly structurally comprises a bracket, an oil net and the like, wherein in the application, under the strong suction effect of a negative pressure fan at the upper end of a fume flue with an air inlet at the lower end, fume generated by kitchens is sucked and discharged outdoors, waste oil and the like in the fume are condensed into liquid through the blocking of the oil net and the air cooling effect, and the liquid flows into a waste oil box from an oil groove at the lower end of the bracket, so that the fume and the like generated by the kitchen are effectively treated, and adverse effects of the fume on personnel health are reduced.

Along with the development of industrial technology, the function of the smoke hood is improved to a certain extent, for example, patent number 202020564159.7 in China and patent name of 'a split assembled stainless steel smoke hood' are issued, and the patent records that 'the split assembled stainless steel smoke hood is attractive in appearance, high in mechanism strength, good in oil separation effect, simple in assembly and high in applicability'. The above-mentioned comparison patent has realized to a certain extent that appearance is pleasing to the eye and intensity relatively increases, and oil removal effect is good equivalent, but is limited by its structure, and the same with other petticoat pipes of current art still has more shortcoming, the concrete expression is as follows. The method comprises the following steps: the oil drain port (oil groove) formed by the first groove and the second groove is connected with the connecting part of the first groove and the second groove in a screw-nut mode, so that in order to prevent poor sealing performance between the two subsequent oil leakage, the two are required to be sealed in a sealing glue beating mode or in a sealing rubber pad mode or the like, the operation process is complicated, inconvenience is brought to staff, and the oil leakage probability is high in practical application when the sealing is poor; and two,: the upper end of the equipment is provided with the bending backboard, so that the cost of the equipment is increased (the backboard area is greatly increased), and the backboard can block rising oil smoke, so that the oil smoke is blocked in a flue, the suction effect of a corresponding negative pressure fan on the oil smoke can be deteriorated, and the oil smoke can bring adverse effects to staff in a kitchen due to relatively low discharge speed. And thirdly,: the bottom beam of the middle support is not provided with an oil port, and in practical application, waste oil in the cooled oil fume can be accumulated at the inner upper end of the bottom beam, so that the subsequent waste oil can be discharged in time and can drop downwards to cause inconvenience to staff in a kitchen. Fourth, it is: the upper end does not have flue installation station, namely flue (generally install outside the equipment upper end and both are separated by a certain distance) lower extreme because with the unable effective combination installation of equipment upper end, in the unable entering flue of oil smoke (increased waste oil adhesion in the oil smoke in the flue outside, and then the probability of dripping on staff's body and kitchen utensils and appliances) as possible, can lead to oil smoke exhaust effect relatively worsen like this, be unfavorable for indoor flue gas to circulate fast and discharge outside. In summary, it is especially necessary to provide a smoke hood that can ensure that the oil tank does not leak oil, the waste oil in the middle bracket can be discharged in time, and the discharge effect of the negative pressure fan on smoke and the like can be improved.
