The invention belongs to the field of cookware, and particularly discloses an intelligent pot which comprises a pot body, a grab handle, a thermocouple and a pot controller, the thermocouple is assembled at the bottom of the pot body, and the pot controller is arranged in the grab handle. The pot controller obtains a corresponding cooking program, the cooking program is configured with a set value of pot temperature associated with time, processing is carried out based on the measured value of the pot temperature detected by the thermocouple and the set value of the pot temperature obtained from the cooking program, and a control signal is generated to control a heating device for heating the intelligent pot. The firepower of the heating device is changed, so that the measured value of the pot temperature reaches the set value of the pot temperature until the cooking program is executed by the pot controller, and food cooking is completed. In the whole cooking process, the intelligent pot operates the heating device based on the obtained cooking program, the temperature of the intelligent pot is automatically controlled, food cooking is completed, user participation is not needed, and delicious food can be made whether the user has cooking skills or not.

The invention discloses a multi-fuel energy-saving furnace, which comprises a furnace panel (1), a furnace basin (2), a furnace ring (3), a furnace cylinder (6), a furnace outer cylinder (7), and three air inlet partitions ( 8), secondary air inlet pipe (12), furnace foot bottom plate (13), third air inlet pipe (14), ash box (15), fire retaining ring (18), furnace foot side plate (19), return air circle (20), exhaust gas outlet hole (29), tertiary air inlet hole (5), secondary air inlet partition (9), furnace bridge (11), furnace tube secondary air inlet hole (17), primary Air inlet (16), stoker (23), stoker chute (24), stoker insert (25) and furnace cover (26). The invention adopts a fully enclosed structure, forms vaporized combustion through three times of air intake to assist oxygen, greatly improves the combustion value, and has the characteristics of various fuels, high efficiency and energy saving, economical and practical, hygienic and environmentally friendly, and long service life.

The invention discloses a circular copper water pipe heated by combustion of a water heater. The circular copper water pipe (1) is drilled with a plurality of upper round holes (11) and lower round holes (12) corresponding to the vertical direction, and the upper round holes The diameter of (11) is less than the diameter of lower circular hole (12), on upper circular hole (11) and lower circular hole (12), be fixed with the copper funnel cup (13) of conical upside-down installation simultaneously, copper funnel cup (13) The cone is fixed on the wall of the upper round hole (11), and the foot is fixed on the wall of the lower round hole (12); this product is mainly used to block the water flow velocity, increase the combustion area, improve thermal efficiency, and save gas.

The invention relates to the technical field of recycling of gutter oil, particularly to a method for producing hot pot fuel from the gutter oil used as a raw material. The gutter oil and sodium hydroxide have a reaction and are subjected to salting-out treatment, solids obtained through salting-out treatment are dissolved and react with sodium citrate, the hot pot fuel is produced, so that the gutter oil is recycled, and the environmental pollution is reduced; besides, raw materials in the treatment process are easy to obtain, the treatment technology is simple, and the producing cost is low; particularly, in the preparation process, distilled water replaces traditional tap water, accordingly, the yield of the fuel is increased, the quality of the fuel is improved, and the burning firepower of the fuel is guaranteed; particularly in combination with control on technological parameters in the preparation process, the gutter oil is optimized during production of the hot pot fuel, the yield of the hot pot fuel is increased, the quality of the hot pot fuel is improved, and the burning firepower of the hot pot fuel is improved.

The invention provides a range hood with a function of recognizing harmful gas and particulate matter in oil fume. A range hood body and a harmful gas and particulate matter detection device are arranged, and the harmful gas and particulate matter detection device is electrically connected with the range hood body. The harmful gas and particulate matter detection device calculates according to thetemperature in a detected cooking area and the concentration of the particulate matter in the oil fume in the cooking area to obtain the current polycyclic aromatic hydrocarbon concentration in the cooking area. According to the range hood with the function of recognizing the harmful gas and the particulate matter in the oil fume, the temperature, PM2.5 concentration, PM10 concentration and the polycyclic aromatic hydrocarbon concentration in the cooking area can be detected, polycyclic aromatic hydrocarbon environment grading can be further carried out on the polycyclic aromatic hydrocarbonconcentration of a current environment, and air quality index assessment is carried out and health levels are obtained; and meanwhile, the range hood is further provided with a wind speed control module, a prompting module and a fire force control module, the current environmental health levels automatically adjust wind speeds and fire force of external cookers, so that the polycyclic aromatic hydrocarbon concentration in the current environment is reduced, and meanwhile, a user is reminded to pay attention to the protection.

The invention relates to a cooker and an anti-dry burning control method and device thereof. The anti-dry burning control method comprises the following steps that a cooking method is acquired, wherein the cooking method is provided with a corresponding alarm temperature threshold value and an anti-dry burning temperature threshold value; a first current temperature of the cooker is acquired, whenthe first current temperature is greater than the alarm temperature threshold value, alarm information is sent out, and outer ring fire is closed; and a second current temperature of the cooker is obtained, and the cooker is closed when the second current temperature is greater than the dry burning prevention temperature threshold value. The cooker and the anti-dry burning control method and device thereof have the advantages that food carbonization is effectively reduced, over cook of pots is reduced, energy is saved, safety is ensured, pots and pans are protected, and the environment is protected; and the cooker and the anti-dry burning control method and device thereof can delay the dry burning of food and prolong the reaction time left for users, and thus the situations of difficult cleaning and damage of the pots and pans caused by carbonization of food in the pots due to more serious dry burning and are avoided.
