In this embodiment, the automatic fire extinguishing apparatus 2 further includes dry powder, and the dry powder is filled in the cylinder cavity 21 and sprayed to the flame, so as to implement the fire extinguishing operation of the automatic fire extinguishing apparatus 2. After the range hood meets a fire, the flame temperature reaches the melting point of the cylinder cavity 21, the cylinder cavity 21 is instantaneously combusted and exploded, and the dry powder in the cylinder cavity can be sprayed to the flame, so that the fire extinguishing effect is realized, and the damage caused by fire is avoided.

An air inlet cavity is arranged in the fume collecting hood 1 and is located at the lower end of the fume collecting hood 1, an air inlet is formed in the front side of the air inlet cavity, a filter plate and a guide plate are arranged in the air inlet cavity of the fume collecting hood 1, the filter plate is located on the upper side of the air inlet and is arranged to incline downwards gradually from front to back, and the guide plate is located on the lower side of the air inlet and is arranged to incline upwards gradually from front to back. Through the arrangement, the guide plate is positioned at the lower end of the filter plate, so that oil smoke can be guided into the filter plate, the oil smoke can better enter the smoke collecting hood 1, and the performance of the range hood is improved.

The air inlet is covered with a baffle glass 23 which can turn over forward to correspondingly open and close the air inlet. The baffle glass 23 is connected with the two sides of the fume collecting hood 1 through the turnover mechanism, and can open or close the air inlet.

As figure 1, the lampblack absorber is at the working process, baffle glass 23 can overturn, and automatic fire extinguishing device 2 sets up in the upper end of baffle glass 23, and it can not influence the normal work of lampblack absorber. In other embodiments, in automatic fire extinguishing device 2's opposite side, can additionally set up a second automatic fire extinguishing device again, additionally set up one again in the inside of collection petticoat pipe promptly, the benefit that sets up like this is, the lampblack absorber is in the course of the work, the fan rotates, under general conditions, the condition of a fire all is in the outside of lampblack absorber, at this moment, the fan produces suction, flame can stretch towards air intake department, so that flame can get into the inside of collection petticoat pipe 1, if additionally set up a second automatic fire extinguishing device in collection petticoat pipe 1's inside, can extinguish the inside flame of getting into collection petticoat pipe 1 rapidly, avoid the intensity of a fire to stretch, simultaneously, also reduce the loss to minimum.

Example two

In this embodiment, a range hood is introduced, range hood still is provided with temperature sensor, automatic fire extinguishing device 2 and controller.

The temperature sensor is used for detecting the temperature value of the range hood. Under the normal condition, the temperature that the lampblack absorber corresponds the position does not have too big change, and when the conflagration breaing out, the temperature that the lampblack absorber corresponds the position can take place great change, and whether the temperature value through detecting the lampblack absorber and corresponding the position judges the conflagration breaing out to make things convenient for automatic fire extinguishing device 2 whether to carry out the operation of putting out a fire.

The automatic fire extinguishing device 2 is used for spraying fire extinguishing medium. When a fire occurs, the automatic fire extinguishing apparatus 2 sprays a fire extinguishing medium for extinguishing the fire, and the automatic fire extinguishing apparatus 2 is integrated with a range hood, so that it is not necessary to additionally provide separate fire extinguishing equipment, such as a fire extinguisher, etc.

And the controller controls the automatic fire extinguishing device 2 to perform fire extinguishing operation when the temperature value is greater than the preset temperature value within the preset time.

Automatic fire extinguishing device 2 can be integrated on the lampblack absorber, through temperature sensor, judges whether the conflagration is, and the operation of putting out a fire is carried out to back controller control automatic fire extinguishing device 2 when catching a fire. Fire extinguishing equipment does not need to be newly added in the kitchen, and the fire extinguishing effect is obviously improved.

In one embodiment of the present invention, the temperature sensor includes a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is used for detecting a first temperature value at the air inlet of the range hood; when a fire disaster happens, the fire at the air inlet is most fierce, so that the temperature at the air inlet can directly reflect whether the fire disaster happens or not, and when the first temperature value at the air inlet reaches the preset temperature, the fact that the fire disaster happens is indicated.

In order to improve the accuracy of putting out a fire, second temperature sensor sets up two at least for detect the second temperature value of lampblack absorber. When the second temperature values at the two positions reach the preset temperature, the fire disaster happens. Wherein, the second temperature sensor is arranged around the air inlet and positioned on the fume collecting hood 1.

In order to improve the accuracy of fire determination, the distance between adjacent second temperature sensors is 150mm to 250mm.

In a preset time, when a first temperature value detected by the first temperature sensor is greater than a preset temperature value, the controller controls the automatic fire extinguishing device 2 to perform fire extinguishing operation; or when the second temperature values detected by the at least two second temperature sensors are larger than the preset temperature value, the controller controls the automatic fire extinguishing device 2 to execute fire extinguishing operation.

Whether the fire is present is judged by the first temperature sensor and the second temperature sensor, and the controller controls the automatic fire extinguishing device 2 to perform fire extinguishing operation after the fire is started.

In the embodiment of the present invention, the automatic fire extinguisher 2 includes a cylinder cavity 21 and an actuator connected to the cylinder cavity 21, and the cylinder cavity 21 is used for storing dry powder.

In order not to influence the normal use, the cylinder cavity 21 is arranged on the surface of the smoke collecting hood 1 of the range hood, and when a fire occurs, the controller can rapidly control the fire extinguishing device to operate.

In this embodiment, different from first embodiment in that, in this embodiment, temperature sensor can detect the outside temperature of lampblack absorber, and when outside high temperature, controller active control automatic fire extinguishing apparatus 2 put out a fire the operation, and when avoiding flame great, automatic fire extinguishing apparatus 2 was exploded by high temperature, carries out the operation of putting out a fire. In this embodiment, the controller can actively control the automatic fire extinguishing device 2 to extinguish fire when the fire just happens or the fire is not big, thereby improving the success rate of extinguishing fire.

In this embodiment, when temperature sensor detected the lampblack absorber temperature higher, the controller can control automatic fire extinguishing device 2 and carry out the operation of putting out a fire, and the controller links to each other with the executor for make the dry powder in the cylinder cavity 21 spray to flame department, wherein, the executor is equipped with the spine portion, and spine portion can puncture cylinder cavity 21, thereby makes the dry powder spray to flame department, accomplishes the operation of putting out a fire.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make modifications or changes to equivalent embodiments using the above-mentioned teachings without departing from the scope of the present invention, and the embodiments in the above embodiments can be further combined or replaced, but any simple modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are also within the scope of the present invention.
