Problems solved by technology

In terms of principle, this Fangming is essentially a spray atomization purification principle, and the adsorption efficiency is low. According to the experimental data, the adsorption efficiency is about 30%. It is only the principle of spray atomization purification, and its adsorption effect is not as good as this patent, and it does not consider the energy saving and oil removal of segmented operation in actual use.

Embodiment 1

[0032] A water curtain type range hood, comprising a casing 1, a range hood arranged on the casing 1, an adsorption mechanism arranged on the side of the casing and matched with the range hood, arranged on the The circulation mechanism on the housing and below the oil fume mechanism and matched with the adsorption mechanism, the exhaust mechanism arranged on the upper part of the housing and matched with the oil fume mechanism, and the exhaust mechanism arranged on the The control mechanism on the housing is used to control the range fume mechanism, adsorption mechanism, circulation mechanism and exhaust mechanism;

[0033] The fume extraction mechanism includes two fume extraction modules arranged symmetrically on the casing 1 , and a partition plate 2 arranged on the casing 1 for separating the two fume extraction modules.

[0034] The range fume module includes an air inlet 30 arranged on the casing 1 and located at the upper part of the casing, a water curtain plate 10 arr...

Embodiment 2

[0042] It differs from Embodiment 1 in that:

[0043] The exhaust motor in the exhaust fan is provided with a water pump driving wheel 8, and the circulating water pump 14 is provided with a water pump driven wheel 12 for the water pump work, and is arranged between the water pump driving wheel 8 and the water pump driven wheel. Between the connecting belt 11.

[0044] The power source of the circulating water pump adopted in this embodiment is the exhaust motor, and the water pump drive wheel can be arranged on its main shaft, and the water pump driven wheel can be set on the water pump, and the rotation of the circulating water pump can be driven by the rotation of the exhaust motor. Therefore, the aqueous solution in the lower part of the adsorption chamber is sucked into the spray pipe, avoiding setting up a drive on the water pump, and reducing the difficulty of control and circuit.

Embodiment 3

[0046] The difference between it and the second embodiment is that the height of the groove wall of the oil discharge groove 24 near the inner wall of the housing 1 is higher than the height of the side wall far away from the inner wall of the housing 1 .

[0047] The height of the side wall away from the inner wall of the housing used in this embodiment is lower than the height of the side wall near the inner wall of the housing near the oil drain groove, which can not only remove oil stains, but also prevent excessive overflow; traditional The sewage discharge method is either directly discharged, or the cleaning solution is replaced regularly, and there is no need to set up an oil discharge tank; however, the above-mentioned solution will either reduce the adsorption effect after long-term use, or consume a large amount of cleaning agent. However, the above-mentioned method is implemented It is very simple, it saves the cost of structure and materials, and can be used to mak...

Abstract

The invention provides a water curtain type range hood. The water curtain type range hood comprises a shell, a smoke exhaust ventilator mechanism arranged on the shell, an adsorption mechanism arranged on the side surface of the shell and is matched with the smoke exhaust ventilator mechanism, a circulating mechanism arranged on the shell, is located below the smoke exhaust ventilator mechanism and matched with the adsorption mechanism, an air exhausting mechanism arranged at the upper part of the shell and matched with the smoke exhaust ventilator mechanism, and a control mechanism arranged on the shell and used for controlling the smoke exhaust ventilator mechanism, the adsorption mechanism, the circulating mechanism and the air exhausting mechanism. According to the water curtain type range hood, adsorption can be carried out on the most of smoke before the smoke enters a motor, the adsorbed smoke can be directly discharged, and the amount of smoke discharged to the atmosphere can be reduced, and 98% of the oil smoke adsorption effect can be obtained under the mutual synergistic effect of all components of the invention.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a water curtain type range hood. Background technique [0002] At present, general range hoods discharge the oil fume directly, or through simple physical collision treatment, a small part of the oil fume is bonded to attachments such as filter screens or filter plates, and most of the oil fume is directly discharged to the outside, causing environmental pollution. During the discharge process, because most of the oily fume has not been treated, some of the oily fume will also adhere to and deposit in the motor impeller, air duct, and exhaust pipe, making the cleaning work more troublesome. [0003] The authorized notification number is CN101327400B, which discloses an oil fume purifier, which includes a main casing with an oil fume passage, and an exhaust fan for providing the oil fume exhaust power for the oil fume passage, and the oil fume passage is provided with an oil ...
