A stove with oil fume exhaust function

Abstract

The present invention provides a stove with a fume exhaust function. The combustion area of ​​the gas stove is located below the heat-conducting panel, and the pot is directly placed on the heat-conducting panel. The infrared heat energy generated by the combustion of the burner transfers the heat energy to the pot through the heat-conducting panel to heat it. The upper surface of the stove becomes neater and easier to clean, and the wind resistance of small and micro fires is stronger. The defect of the pot placed on the elevated pot rack in the prior art is overcome, and the combustion is more stable. Moreover, on the one hand, the fan on the vertical arm absorbs and exhausts the fume generated during the cooking process of food. On the other hand, the same fan can also generate pneumatic action when it is running, which promotes the hot fume generated by the combustion in the combustion chamber to be sucked into the vertical arm and then discharged together with the fume-containing airflow sucked from the fume suction port. It can not only absorb and exhaust, process and purify the fume, but also promote the air convection circulation when the closed burner is burning, so that the combustion is more complete, and one machine has multiple effects.

Description

Technical Field

[0001] The invention relates to the field of kitchen equipment, and in particular to a stove with an oil fume exhaust function. Background Art

[0002] With the improvement of people's living standards, living environment and the emergence of open kitchens, consumers are increasingly demanding products that are beautiful, convenient, safe, easy to clean, and have high space utilization, especially high flat area utilization. At the same time, with the emergence of open kitchens and the increase in the density of urban residential buildings, products that can purify oil fumes are also imminent.

[0003] However, at present, gas stoves basically adopt external combustion and external pot supports, which are not beautiful in appearance, inconvenient to use, difficult to clean, and unstable in pot placement, which poses certain safety hazards. There are also many problems that have not been effectively solved, such as low space utilization, especially low utilization of flat area, etc., and the stoves and range hoods sold on the market are basically separated. Although some integrated stoves have appeared in recent years, they still adopt open combustion heating and external pot supports. With the promotion of the overall kitchen design concept, the integrated stove adopts an independent module design, which cannot meet the needs of the overall kitchen aesthetic design and cannot be recognized by consumers in first- and second-tier cities. In addition, the range hoods and integrated stoves on the market do not use oil fume purification technology, and the oil fume is directly discharged to the outside, causing great harm to the urban atmospheric environment. Gas stoves also have many problems, such as low thermal efficiency, exhaust gas carbon monoxide and nitrogen oxides generated during combustion are all discharged indoors, low fire and micro fire wind resistance is relatively weak, the existing gas stove pot bracket is not very stable to place the pot, and the existing gas stove is not convenient to clean, especially the pot bracket 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 in modern cities presenting a large city with small space living environment, the use of every square meter of indoor space is very important.

If qualified, the user can operate the gas cooker; further preferably, it also includes an interconnected screen movement and split-screen display system.

[0047] The present invention has at least the following beneficial effects:

[0048] According to the present invention, the combustion area of ​​the gas stove is located below the heat-conducting panel, and the pot is placed directly on the heat-conducting panel. The infrared heat energy generated by the combustion of the burner transfers the heat energy to the pot through the heat-conducting panel to achieve its heating. Compared with the prior art, the existing pot support exposed on the upper surface of the stove can be eliminated, so that the upper surface of the stove becomes neat and easy to clean, and the wind resistance of small fire and micro fire is stronger. On the other hand, during the cooking process, the pot can be placed flat on the heat-conducting panel, which overcomes the defect of the pot being placed on the elevated pot support in the prior art and prevents unsafe accidents. Since there is no need for a pot support, the space on the panel surface is no longer occupied. When the user does not use the burner to heat the cooking dish, the panel surface space can be used by the user for other purposes, such as placing kitchen equipment or processing food in the panel area. Moreover, the upper surface of the stove is neater and flatter, making the entire stove and panel easier to clean.

[0049] At the same time, since the burner, bottom wall, and annular side wall are located below the heat-conducting panel, compared with the open-air combustion in the prior art, the combustion area is not affected by wind in the air, etc., and the combustion is more stable, especially when the fire is small or micro, the combustion is more stable and safer.

[0050] A more prominent beneficial effect is that, since the vertical arm is arranged on the stove body in the present invention, the vertical arm is provided with an oil fume suction port above the heat conduction panel, a fan and an oil fume exhaust channel are arranged inside the vertical arm, the oil fume exhaust channel is connected to the oil fume suction port, an exhaust port for discharging hot smoke in the combustion chamber is arranged on the heat insulation and flow guiding device, one end of the hot smoke exhaust pipe 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 to form a negative pressure at the oil fume suction port to inhale oil fume, and also to form a negative pressure at the exhaust port to inhale hot smoke and make the hot smoke flow upward into the oil fume exhaust channel. Therefore, on the one hand, when the fan on the vertical arm is running, the oil fume generated during the cooking process of food is sucked and discharged, and on the other hand, the same fan can also generate a pneumatic effect when running, promoting the hot smoke generated by the combustion in the combustion chamber to be sucked into the vertical arm and then discharged together with the oil fume-containing airflow sucked from the oil fume suction port, which can not only suck and discharge, process and purify oil fume, but also promote the air convection circulation during the combustion of the closed burner, so that the combustion is more complete, and one machine has multiple effects.

[0051] Furthermore, the blocking and diverting component is arranged to block and divert the hot flue gas diffused to the blocking and diverting component, so that when the high-temperature hot flue gas generated by the burner burns and flows from the combustion surface of the burner to the smoke exhaust port, the blocking and diverting component has a blocking and diverting effect on the hot flue gas, so that the process of the hot flue gas flowing to the smoke exhaust port is delayed and a turbulent effect is formed, so that the hot flue gas contacts the heat-conducting panel and / or the blocking and diverting component for a longer period of time to fully release and transfer heat energy, and the hot flue gas and the radiated infrared rays that form the turbulent effect are repeatedly refracted within the spacing and then radiate heat energy outward from the heat-conducting panel in a direction, thereby significantly improving the infrared heat radiation effect above the heat-conducting panel, and significantly improving the thermal efficiency of the fully enclosed gas cooker.
