Description

Stove with oil fume exhaust function

Technical field

The invention relates to the field of kitchen equipment, in particular to a cooker with a function of exhausting oil fume.

Background technique

With the improvement of people's living standards, the improvement of the living environment, and the emergence of open kitchens, consumers are increasingly demanding products with beautiful appearance, convenience, safety, easy cleaning, high space utilization, especially high utilization of flat area. At the same time, with the emergence of open kitchens and the increase in urban residential building density, products that can purify oil fume are also imminent.

However, the current gas stoves basically use external combustion and external pot holders, which are not beautiful in appearance, inconvenient to use, difficult to clean, and unstable in placing the pot. There are certain safety hazards, and the space utilization rate is not high, especially Many problems such as the high utilization rate of flat area have not been effectively solved, and the stoves and range hoods currently on the market basically adopt a separate design. Although some integrated stoves have appeared in recent years, open combustion heating and external pot holders are still used. With the promotion of integrated kitchen design concepts, integrated stoves are designed with independent modules, which cannot meet the needs of integrated kitchen aesthetic design. , The first- and second-tier cities cannot be recognized by consumers, and the range hoods and integrated stoves on the market do not use the oil fume purification treatment technology, and the oil fume is directly discharged outdoors, causing great harm to the urban atmospheric environment. Similarly, gas stoves also have many problems, such as: low thermal efficiency, exhaust gas carbon monoxide and nitrogen oxides produced during the combustion process are all discharged indoors, and the wind resistance of small fires and low fires is relatively weak. The existing gas stoves The pot holder is not very stable to put the pot, and the existing gas stove is not convenient to clean, especially the pot holder and the liquid tray are more difficult to clean. In addition, the pot bracket on the existing gas stove occupies the entire plane area of the gas stove, which is a great waste of plane space, especially the modern city presents the living environment of a small space in a big city, which affects every square meter of indoor space. Utilization is very important.

In addition, in the prior art non-open gas stove without a pan frame, a heat conduction panel is simply provided above the burner, and the hot smoke generated by the combustion directly diffuses into the air, which has many defects during use. For example, the heat conduction efficiency of the heat conduction panel is low, the temperature of the cookware is slow, and the heat conduction cannot realize the directional transmission, causing unnecessary high temperature in other areas of the stove panel, which causes a serious decrease in thermal efficiency. On the other hand, it is easy to scald the operator and damage the food. instrument.

The present invention has at least the following beneficial effects:

According to the present invention, the combustion area of the gas cooker is located under the heat-conducting panel, the pot is directly placed on the heat-conducting panel, and the infrared heat generated by the combustion of the burner is transferred to the pot through the heat-conducting panel to realize its heating. Compared with the prior art, the existing pot holder exposed on the upper surface of the cooker can be eliminated, so that the upper surface of the cooker becomes tidy, convenient to clean, and has stronger wind resistance for small and slight fires. On the other hand, the pot can be placed flat on the heat conducting panel during the cooking process, which overcomes the instability defect that the pot is placed on the elevated pot rack in the prior art, and prevents unsafe accidents from occurring. Since there is no need for a pot holder and no longer occupy the space on the surface of the panel, when the user does not use the burner to heat cooking dishes, the space on the panel surface can be used by the user for other purposes, such as placing kitchen equipment or processing ingredients in the panel area. Moreover, the upper surface of the cooker is cleaner and the surface is flat, making the entire cooker and panel easier to clean.

At the same time, the burner, bottom wall, and annular side wall, because the burner is located under the heat conducting panel, compared with the open-air combustion in the prior art, the combustion area is not affected by the wind in the air, and the combustion is more stable, especially It is more stable and safer to burn in small fires and low fires.

The more prominent beneficial effect is that, since the neutral arm of the present invention is arranged on the cooker body, the vertical arm is provided with an oil fume suction port above the heat conducting panel, and a fan and an oil fume exhaust passage are arranged inside the vertical arm, and the oil fume exhaust passage is connected to the oil fume suction port , The heat insulation guide device is provided with an exhaust port for discharging hot smoke in the combustion chamber, one end of the hot smoke discharge channel is connected to the exhaust port, and the other end is connected to the oil fume exhaust channel, and the fan is arranged on the oil fume exhaust channel, A negative pressure is formed at the oil fume suction port to inhale oil fume, and a negative pressure is formed at the exhaust port to inhale hot fume so that the hot fume flows upward into the oil fume exhaust channel. Therefore, on the one hand, the fan on the vertical arm sucks and discharges the fume generated during the cooking process when the fan is running. On the other hand, the operation of the same fan can also generate aerodynamic effects to promote the hot smoke generated by the combustion in the combustion chamber to be sucked into the vertical arm. Exhaust together with the airflow containing oil fume sucked in from the oil fume suction port, not only can absorb and treat the oil fume, but also promote the air convection circulation during the combustion of the closed burner, so that the combustion is more complete, and the machine has multiple effects.

Further, the blocking and splitting component is arranged to block and split the hot smoke diffused to the blocking and splitting component, so that the high-temperature hot smoke generated by the combustion of the burner blocks the flow from the combustion surface of the burner to the exhaust port. The shunting component has a blocking and shunting effect on the hot flue gas, so that the process of the hot flue gas flow to the exhaust port is delayed and a turbulent effect is formed, so that the hot flue gas contacts the heat conducting panel for a longer time and/or blocks the shunting component to fully release and transmit The thermal energy, the hot smoke and the radiated infrared rays that form the turbulence effect are repeatedly refracted within the distance, and then the thermal energy is radiated and transferred from the heat conduction panel to the outside, which significantly improves the infrared heat radiation effect above the heat conduction panel, and significantly improves the performance of the fully enclosed gas cooker. Thermal efficiency. Further, the heat insulation guide device prevents the heat from spreading, so that the heat generated by the combustion of the burner is concentrated in the combustion chamber and is radiated and released by the heat conducting panel, so that the upper part of the burner has a higher heat radiation effect, and other areas of the cooker are not easy to produce inconvenience. The necessary heat transfer, on the one hand, is more thermally efficient, on the other hand, it is safer.

Further, the enclosed gas stove has a directional heat conduction panel, which is more capable of higher thermal efficiency on the one hand and safer on the other hand.
