Description
Technical Field
The utility model relates to the technical field of kitchen and toilet articles, in particular to a detection and alarm system for the working state of a range hood.
Background
The fume exhaust fan is also called fume exhaust fan and is one kind of kitchen appliance for purifying kitchen environment. The kitchen range is arranged above a kitchen range, can rapidly pump away waste generated in combustion of the range and oil smoke harmful to human bodies in a cooking process, is discharged outdoors, and simultaneously condenses and collects the oil smoke, so that pollution is reduced, air is purified, and the kitchen range has the effects of gas protection and explosion prevention.
At present, most of the range hoods on the market are manually operated by a person or are linked with a kitchen range by using an integrated kitchen range mode, namely, the kitchen range is opened, and the range hoods are also opened. There are several problems with both of these approaches: human intervention is needed to judge the oil smoke condition and control the switch to adjust the air quantity. Linkage electricity consumption can also force to start the fan when no oil smoke exists, and noise pollution is caused. When no person is in the house, the whole house is filled with oil smoke, and if the oil smoke is heavy, fire hazard can be generated.
In order to solve the problems, the range hood can be automatically opened according to the oil smoke concentration and can be automatically adjusted to be applied. For example, patent CN106051875a describes a range hood with various automatic gear control, by providing a fume probe and a temperature sensor, the fume generation condition and escape condition can be accurately grasped, so that the range hood can automatically control the gear and the air quantity along with the change of the fume concentration, the hands of people are liberated, the intelligent degree is high, and the fume removal effect is good.
However, the range hood only carries the fume detection in a near area and the range hood is linked, and when a certain amount of fume escapes even if the range hood is opened, an outgoing owner cannot be informed at the same time. Therefore, the range hood only performs the opening of the range hood, but cannot remotely inform a homeowner. Meanwhile, only the oil smoke in the cooking area space can be detected. If the oil smoke in other areas of the kitchen is scattered, the range hood cannot be detected and turned on. In addition, in some cases, the user may forget to turn off the gas cooker when going out, and the long-time combustion of the cooker may cause fire, so that the range hood in the prior art cannot sense whether someone is in the room or not, and cannot automatically turn off the gas cooker according to the activity condition of the person.
