Abstract

The utility model discloses a pot rim frame type range hood and belongs to the field of range hoods. The range hood consists of an axial flow fan chamber and an annular air passage frame body, wherein a horizontal partition plane is arranged in the inner cavity of the annular air passage frame body to divide the inner cavity of the annular air passage frame body into an upper air intake passage and a lower air exhaust passage; the horizontal partition plane is uniformly distributed with vent holes; the internal annual surface of the upper air intake passage is uniformly provided with air inlets; the outlets at two ends of the lower air exhaust passage are communicated with the axial flow fan chamber; the diameter of a pot rim is smaller than the diameter of the internal cavity of the annular air passage frame body; a cooking pot can be just held in the annular air passage frame body; the air inlets of the upper air intake passage are a little bit higher than the rim of the cooking port; and when an axial flow fan is started to generate a negative pressure in the air passages, under the action of the sucking negative pressure of the pot rim frame type range hood, oil fume is first sucked into the upper air intake passage from the air inlets and then sucked into the axial flow fan chamber from the two ends of the lower air exhaust passage after passing through the vent holes to be discharged from a flue. The pot rim frame type range hood has the advantages of scientific design, simple structure, obvious oil fume suction effect, oil fume pollution reduction, environmental purification and convenient use and maintenance.

Description

A kind of pot of frame formula smoke exhaust ventilator

Technical field

A kind of pot of frame formula of the utility model smoke exhaust ventilator belongs to the smoke exhaust ventilator field, is specifically related to household smoke exhaust ventilator.

Background technology

Traditional smoke exhaust ventilator be arranged on the kitchen range cooker directly over, the oil smoke that produces when relying on the exhausting ability of air exhauster that cooker is cooked is forced to take away, it is not strong that this mode is aspirated the oil smoke ability, suction oil smoke poor effect.Exploitation now has the integrated kitchen range of a kind of downdraft smoke pumping, and its oil smoke suction and kitchen range set are designed to one, though this design smoke pumping ability strengthens, but, this kitchen range complex structure, involve great expense, and the pot body sinks to being embedded in kitchen range, so the inconvenience of use, the pot limit is overheated scalds one's hand easily.Simple and direct, easy to use, the effective smoke exhaust ventilator of suction oil smoke of market call structure.

The utility model content

The purpose of this utility model provides a kind of pot of frame formula smoke exhaust ventilator, and the oil smoke suction effect with direct and strong swabbing action raising smoke exhaust ventilator reduces fume pollution, purification run person's environmental aspect, and operation and maintenance is convenient.

The utility model purpose is achieved by the following technical solution:

This pot of frame formula smoke exhaust ventilator is made up of axial flow blower chamber and ring type air flue framework, characteristics are that ring type air flue framework 1 is partly connected to form by A, B two, this ring type air flue framework inner chamber is provided with horizontal closing surface 4 and is divided into top air intake duct 2 and bottom gas off-take 3, horizontal closing surface 4 is evenly equipped with passage 5, the two ends D of top air intake duct 2 shuts, its inner ring surface is evenly equipped with air admission hole 6, the outlet of bottom gas off-take 3 two ends is communicated with the axial flow blower chamber respectively, ring type air flue framework is fixedly mounted on the kitchen range abutment wall body, and ring type air flue framework center is concentric with fiery tool.

The utility model design science, structure is simple and direct, and the effect of suction oil smoke is remarkable, reduces fume pollution, has purified operator's environmental aspect, and operation and maintenance is convenient.

Fig. 4 is that schematic diagram is shut in air intake duct termination, ring type air flue framework top

The specific embodiment

How existing accompanying drawings the utility model is implemented:

The design's ring type air flue framework 1 is by A as shown in Figure 1, B two partly framework connects the L composition, empty diameter is greater than pot limit diameter in the ring type air flue framework, its framework inner chamber is the square-section of the high 6cm of wide 2cmx, the inner chamber of ring type air flue framework 1 is provided with horizontal closing surface 4 this inner chamber is separated into the top air intake duct 2 of the high 2cm of wide 2cmx and the bottom gas off-take 3 of the high 4cm of wide 2cmx as shown in Figure 2, level is evenly equipped with the passage 5 of Φ 5mm every face 4, the inner ring surface of top air intake duct 2 is evenly equipped with two row Φ 8mm air admission holes 6 referring to Fig. 3,2, this air intake duct two ends D shuts as shown in Figure 4, the outlet of its underpart gas off-take 3 two ends is communicated with axial flow blower chamber F respectively, ring type air flue framework is fixedly mounted on the kitchen range abutment wall body, keep ring type air flue framework center concentric with fiery tool, during use, frying pan pot limit diameter is less than empty diameter in the ring type air flue framework, frying pan places fiery tool top, just in time drop in the ring type air flue frame, air intake duct 2 inner ring surface air admission holes 6 in top are a little more than dish pot edge, open axial flow blower, form negative pressure in the air flue, the oil smoke that produces in the pot is under the suction suction function of the ring type smoke exhaust ventilator on pot limit, oil smoke enters top air intake duct 2 from the air admission hole 6 of ring type air flue framework top air intake duct 2 inner ring surfaces, the passage 5 that passes horizontal closing surface 4 enters bottom gas off-take 3, as shown in Figure 1, the direct connection shaft flow fan chamber F in bottom gas off-take 3 two ends, because of being subjected to the obstruct of direct strong pumping effect of axial flow blower and air curtain, oil smoke promptly is forced into and bleeds, and discharges through flue again.

The annular air channel frame can unload cleaning.

The utility model size design is suited measures to local conditions, and not limited by above-mentioned embodiment specification.
