Problems solved by technology

[0002] In the existing commercial high-power cooker, the range hood uses a high-power fume hood to suck out the oil fume, and there is a large amount of fresh air without oil fume. The power of the exhaust fan is very large, which wastes unnecessary energy
Especially for commercial range fume hoods, the power consumption of air extraction is often more than a dozen kilowatts, and the waste is particularly prominent.
At the same time, when the chef stirs the pot, seasons and loads the dishes, the oil fume overflows the hood, and the ventilation cannot be concentrated and the effect is not good, so that the oil fume spreads in the kitchen, but the power of the ventilation is not reduced, the effect of the oil fume is not good, and it affects the on-site personnel good health

Embodiment 1

[0029] The first embodiment: the burner fume hood 2 and the overturning fume hood 1 are provided with independent exhaust passages and exhaust ports, and exhaust fans are respectively arranged behind the exhaust ports.

[0030] Set a burner position sensor for the burner position of the stove, and set a pot position sensor for the pot position. When the burner position sensor detects that the hot pot is at the burner position, turn on the exhaust fan of the burner fume hood 2; in the pot position When the sensor detects that the high-temperature pot is in the inverted position, the exhaust fan of the inverted fume hood 1 is turned on. The two exhaust fans can operate independently. When the burner position sensor does not detect that the high temperature cookware is in the burner position, turn off the exhaust fan of the burner fume hood 2; when the burner position sensor does not detect the high temperature cookware in the fire position When in position, turn off the exhaust fan...

Embodiment 2

[0032] Embodiment two: such as figure 1 or figure 2 , The fire vent fume hood 2 and the pan pot fume hood 1 are provided with a common exhaust fan, share the exhaust channel, and set independent exhaust fans at other positions.

[0033] Such as figure 1 , 2 , The burner fume hood 2 and the overturned fume hood 1 are arranged in the same fume hood, separated by a partition 3, and the angle between the partition 3 and the axis of the exhaust fan is not greater than 10°, Since the hood 1 is arranged on the side of the operator of the burner hood 2, the plane of the partition basically faces the operator, and is raised facing the operator. A common exhaust port is provided behind the partition 3, and a common exhaust fan is provided behind the exhaust port.

[0034] The pot position sensor 14 transmits a signal to the induction actuator 11 when the high-temperature pot is at the pot-up position, and the induction actuator 11 turns on the exhaust fan and the pot-up exhaust port 5, and ...

Embodiment 3

[0039] Embodiment three: such as figure 1 or figure 2 , The fire vent fume hood 2 and the pan pot fume hood 1 are equipped with a common exhaust fan, and share the exhaust channel, and the exhaust channels in other positions also share the same exhaust fan.

[0040] The burner fume hood 2 and the overturned fume hood 1 are arranged in the same fume hood, separated by a partition 3, and the angle between the partition 3 and the axis of the exhaust fan is not more than 10°, because The fume hood 1 is arranged on the side of the operator of the burner fume hood 2, and the plane of the baffle basically faces the operator, and is raised facing the operator. A common exhaust port is provided behind the partition 3, and a common exhaust fan is provided behind the exhaust port.

[0041] Valves are set in the pan-pan suction port 5 and the flame-vent suction port 4 between the partition plate and the exhaust fan. When the stove is in use, the exhaust fan keeps running. By changing the valv...

Abstract

The invention discloses a cooking fume exhaust method for an energy-saving stove. A fire hole cooking fume cover, a pot cooking fume cover and a dish cooking fume cover are arranged over the stove, and the pot cooking fume cover is arranged on one side of an operator for the fire hole cooking fume cover. An induction actuator, an exhaust fan and a plurality of pot position sensors are arranged, wherein the exhaust fan and the pot position sensors are electrically connected with the induction actuator, when the stove is used, the pot position sensors detect pot positions and transmit signals to the induction actuator, and the induction actuator turns on the exhaust fan and a corresponding suction opening and turns down other suction openings. The suction openings of the cooking fume cover and an exhaust channel track cooking fume generation sources in real time and prevent cooking fume from overflowing, the exhaust cooking fume is recycled as fuel, the energy sources are greatly saved, the energy source consumption is remarkably reduced, and meanwhile the cooking fume purification rate is obviously increased. According to the method, a pot can be recognized and tracked in a pertinence manner, multi-position tracking can be achieved with the small-power exhaust fan, cooking oil is effectively exhausted in an orientation manner, a better cooking fume exhausting effect is guaranteed, the energy consumption is greatly reduced, and the energy sources are saved.

Description

Technical field [0001] The invention relates to a stove energy-saving technology, in particular to a method for removing oil fume from an energy-saving stove. Background technique [0002] In the existing commercial high-power stoves, the range fume hood uses a high-power fume cupboard to extract the fume, and there is a large amount of fresh air without fume, which requires a large exhaust fan power and wastes unnecessary energy. Especially for commercial range fume hoods, the exhaust energy consumption is often more than a dozen kilowatts, and the waste is particularly prominent. At the same time, the cooking fume overflows the fume hood when the cook is inverting the pot, seasoning and serving the plate, and the exhaust cannot be concentrated and the effect is not good, so that the cooking fume is diffused in the kitchen, and the exhaust power is not reduced, and the effect of the cooking fume is not good, affecting the on-site personnel Healthy. Due to the long working hour...
