Description

Energy-saving range hood

technical field

The utility model relates to the technical field of kitchen equipment, in particular to an energy-saving range hood, which is suitable for kitchen equipment in ordinary families, restaurants and hotels.

Background technique

Range hoods and gas stoves are indispensable household appliances in the kitchen. Most of the commonly used range hoods and gas stoves are designed in a single structure. There is no mutual signal transmission between the two, and they all use a separate control system. Just there is the defective of following aspects in use like this:

(1) After the gas stove is started, the pumping unit cannot be started at the same time in time, resulting in the retention of oil fumes, which in turn causes certain harm to the indoor environment;

(2) When the range hood is started in advance, and then the gas stove is started, this will cause a waste of electric energy for the range hood;

(3) When the gas stove is cooking on a high fire, a lot of oil fume will be generated, and the range hood always operates at a certain power, which cannot be adjusted. If the power is too high, it will cause waste of electric energy, and if the power is too small, it will cause fumes. The effect is not good, and intelligent control cannot be performed;

(4) When the gas stove is in a state of high fire, the ventilation volume of the gas will increase accordingly

Although a gas stove and range hood linkage system is disclosed in CN 205783190 U, this linkage system is only a simple synchronous gas stove and range hood to ensure that both start and close at the same time, and does not solve the above-mentioned intelligent problem. The purpose of regulation and energy saving; CN 202371774 U discloses a system for the linkage control of gas stoves and range hoods. This system adds a pair of dial switches to set the address codes of gas stoves and range hoods , so as to realize the binding of the gas cooker and the range hood, the actual technical problem to be solved is to realize the linkage of the two, and it does not involve how to automatically adjust; the smart smoke range system is disclosed in CN 203928029 U, which is mainly aimed at the existing In the technology, the smoke stove system cannot prompt the user whether the gas is turned off in time, and a control system that can remotely operate and turn off the gas stove in time is provided.

To sum up, neither the gas stove nor the range hood commonly used at present can well solve the function of synchronous feedback adjustment of the two in the prior art, and ultimately achieve the effect of energy saving.
