Abstract
The utility model relates to an air exhausting fan which comprises a machine seat, a fan head, a protective door and an oil holder. The utility model is characterized in that the protective door is arranged on an air inlet. An airflow channel and the bottom thereof form the incline shape, and the airflow channel is communicated with the oil holder on the underside. The whole fan head is arranged in the airflow channel. When the protective door is opened, the utility model is not flushed by the oil fume. Thus, the utility model has very small resistance and noise, big air capacity and little separated oil-water; the oil-water can not splash, oil is not cumulated in the channel, the oil can not be exhausted to the room interior and the room exterior, and the utility model can not cause the secondary pollution for the room interior and the room exterior; when the air exhausting fan is closed, the parts in the air exhausting fan are arranged out of the door, and the indoor environment is improved greatly; the device has simple structure, low cost, and particularly, the device has very convenience for mounting and cleaning.
Description
The utility model relates to a kind of exhaust, particularly gets rid of the ventilating fan that kitchen fume is used.
In order to get rid of oil smoke, steam and the gas of combustion that production, test and when cooking produce, be extensive use of ventilating fan.This all has bigger improvement to indoor air and Kitchen hygiene environment.The ventilating fan of use and market sale at present, in order to prevent the invasion and attack of outdoor wind, dirt and mosquito, mostly be provided with protective door different structure, that utilize its switches of control such as exhaust wind-force or centrifugal force at its relief opening, but these structures have caused resistance and noise to increase, air displacement reduces, and even more serious is a large amount of separation and the adhesion that causes profit; When the impeller of oil smoke by high speed rotating, there are a large amount of profits from flue gas, to separate, and be thrown on the inlet end panel by impeller and around the space in go, in addition, oil smoke washes away fan head and air-flow path internal surface, also produces the separation and the adhesion of profit, removes isolated profit for convenience, Gong Ying ventilating fan in the market, the following oil containing device that all is provided with at the inlet end panel comes together in the oil containing device profit that condenses on the panel, so that regularly remove.But this structure is to being thrown to the profit in the surrounding space, and cut little ice by protective door, fan head and the isolated a large amount of profits of air-flow path internal surface, because drainage difficulty, the latter still productive set in the bottom of air-flow path, the profit that overflows is also let drift, this not only makes and cleans difficulty, and has caused indoor, outdoor serious secondary pollution.
The purpose of this utility model provides a kind of improved ventilating fan, its its protective door does not produce profit when exhaust separation, resistance and noise, it can prevent splashing of impeller when rotation profit effectively, can also with this profit be drained in time in the lump in the oil containing device so that unified processing by fan head and the isolated profit of air-flow path internal surface.
The purpose of this utility model be achieved in that with protective door be arranged on air-flow path in the support suction port and with its flexible connection, this protective door withdraws from from air-flow path when opening, the internal surface of this air-flow path and bottom thereof all manufacture to unobstructed skewed of in its lower section oil containing device discharge opeing is set, and described fan entirely is built in this air-flow path.Protective door is arranged on suction port, adopt hinge type or suspension type or slide track type or flexible connection such as snap-in between it and the suction port, because this protective door has left air-flow path when opening, it is not subjected to washing away of oil smoke air-flow, has therefore fundamentally eliminated the oil-water separation, resistance and the noise that produce because of the protection shop front; The internal surface of air-flow path and bottom thereof all manufacture to unobstructed skewed of in its lower section oil containing device discharge opeing is set, therefore aggegation can be in time at the profit of internal surface and bottom thereof, flow in the following oil containing device unobstructedly, be convenient to regular processing: because whole fan head all is built in this air-flow path, impeller rotates on the internal surface that isolated profit will be thrown to air-flow path and does not outwards splash, it will be together with isolated profit in the air-flow path, under action of gravity, flow to the bottom of air-flow path along the internal surface of air-flow path, and flow into together down and with oil containing device that it is communicated with in, thereby guaranteed that the profit in the air-flow path can not accumulate in the support.The bottom of air-flow path can be communicated with through the oil containing device of inlet and outlet mouth below it, and also the outage that can offer through its bottom, groove etc. are introduced its profit in the oil containing device, also air-flow path bottom and oil containing device can be fused.
The cross section of air-flow path is circular or Hexagon or ellipse in the support.Also to other unobstructed leaning structure of following oil containing device discharge opeing.The internal surface of air-flow path and bottom thereof should be avoided forming horizontal or other gather the structure of profit easily, so as to make isolated profit can be in time, unobstructedly drain in the oil containing device.
The longitudinal section of air-flow path is cylindricality or taper or tubaeform etc. in the support.The longitudinal section of this air-flow path can be a flaring along airflow direction, or convergent, or their combination.
The air-flow path bottom tilts to suction port in the support.Like this, the profit in the machine can cause in the oil containing device through suction port row, and this can make operation more simple and convenient.
Protective door of the present utility model is not owing to be subjected to washing away of oil smoke air-flow when exhaust, so exhaust resistance is very little, and air displacement is big, and noise is low, and the separation of profit is greatly reduced, and has improved the sanitation and hygiene situation; When closing protective door with greasy dirt surface in the machine refuse outdoor, and do not estimate the interior space, created advantage for further improving the indoor and outdoor environment; Air-flow path internal surface that tilts and bottom thereof are communicated with following oil containing device, and the profit in the support can in time be got rid of and handle: whole fan is built in the air-flow path, so has prevented splashing of profit effectively; Because component are few, simple in structure, with low cost; What is more important makes to clean and becomes very simple, easy to operate.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation according to the ventilating fan that the utility model proposes;
Fig. 2 to Fig. 4 is several structural representations according to the ventilating fan air-flow path cross section that the utility model proposes.
