Description

Baking oven

Technical Field

The invention relates to the technical field of ovens, in particular to a smokeless oven.

Background

In the smokeless roaster in the prior art, the smokeless effect is poor. For example, the CN109259617A smokeless oven has a filter screen to absorb the oil smoke, the oil smoke is sucked into the oven from the periphery of the baking tray, but no circulating air duct is formed, and the oil smoke is filtered by the filter screen and then discharged out of the oven from the bottom. Because the filtering effect of the filtering net is limited, the oil smoke can not be completely filtered by one-time filtering, and the unfiltered and clean gas is discharged without circulation, which can also cause air pollution. Smokeless ovens, like CN105212770A, have the following drawbacks: 1. although a circulating oil fume air duct is formed, the oil fume air duct is characterized in that wind blows from one side of the oven to the other side, so that if wind power is not well controlled, oil fume flows easily gush out of the oven from the blown side, air is polluted, and discomfort of a user at the blown side is particularly caused; 2. the effective air draft distance of the fan is not fully exerted, the shape of the oven can only be made into a rectangle, the oven is limited not to be made larger, and more people cannot use the oven at the same time.

Disclosure of Invention

The invention overcomes the defects of the prior art and adopts the following technical scheme:

the utility model provides an oven, includes base and overware subassembly, has installed the fan in the ascending space of base, and the overware subassembly has set up the wind gap in the fan top on the overware subassembly, and aforementioned wind gap from the top down runs through the overware subassembly has set up a plurality of ventilation holes around the overware subassembly, leaves certain ventilation clearance between the side on overware subassembly downside and the base.

The air opening and the ventilation hole are arranged, so that air flow does not blow from one side of the oven to the other side, but flows to the air opening in the middle of the baking tray assembly from the periphery of the baking tray assembly, and then flows to the space above the base through the air opening. Because a certain ventilation gap is reserved between the lower side surface of the baking tray component and the upper side surface of the base, the airflow flows to a plurality of ventilation holes around the baking tray component from the ventilation gap and finally flows to the air openings on the baking tray component through the ventilation holes. The air flow is driven by the fan and repeated in this way, so as to form a circulation.

The circulating gas flow is described above. In order to realize the effect of filtering oil smoke in air current, a water tank is arranged between a fan and the bottom of a base, the air current caused by the rotation of the fan is blown downwards to the water surface of the water tank at a certain angle, the combination of the oil smoke in the air current and water is realized, and the oil smoke is further filtered. The air flow passing through the water surface finally flows from the ventilation gap to a plurality of ventilation holes around the baking tray component and then flows from the ventilation holes to the air openings on the baking tray component. The above-described flow pattern of the air flow may be referred to as a forward motion of the air flow.

In order to guide the air flow flowing through the fan to the water surface, the fan support is sleeved on the fan, a plurality of air guide openings are formed in the fan support, the air guide openings surround the fan, the air flow flows to the water surface of the water tank after passing through the air guide openings, and more air flow is blown to the water surface, so that a better oil-smoke separation effect is achieved.

This patent also can realize air current reverse motion, namely, around from the air port flow direction overware subassembly in the middle of the overware subassembly, reach after a plurality of ventilation holes around the overware subassembly again and leave certain ventilation gap between the side on overware subassembly downside and the base, then downward flow direction base bottom, the central authorities that flow to base bottom all around in base bottom are the surface of water through the basin simultaneously, then base bottom central authorities upwards are sucked by the fan again, blow the starting point of getting back to the air port in the middle of the overware subassembly, so relapse, form the reverse circulation. In order to realize the reverse movement of the airflow, the blades of the fan need to be replaced by the blades with special shapes.

The air ports comprise a first air port and a second air port, the first air port is arranged on the baking tray, and the second air port is arranged on the inner shell; the fan is arranged in the center of the base, the air opening is arranged in the center of the baking tray, the second air opening is arranged in the center of the inner shell, and the fan, the first air opening and the second air opening are opposite to each other in the vertical direction. The advantages of such a design are: the maximum use of the effective draft distance of the fan when the fan and the air outlet are centrally located allows the grill to be made larger and preferably be made in a centrally symmetrical shape, such as square or circular, while allowing more people to use it around, for example seven or eight people.

When the fan rotates forwards, airflow flows from top to bottom in the middle of the oven, the air suction port is formed in the middle of the oven, and the air blowing port is located around the oven; when the airflow moves reversely, the flowing direction of the airflow is opposite, the air suction ports are positioned around the oven, and the air blowing ports are positioned in the middle of the oven. Tests show that the former is that the air suction opening of the oil smoke air channel is positioned in the middle of the oven, and the air blowing opening is positioned around the oven to have better oil smoke suction effect.

And the baking tray is provided with a wind blocking cover for blocking the upper part of the first wind opening. The wind shield cover blocks the passage of the clean air above the first air opening to the first air opening. Due to the design, the fan can more efficiently suck the oil smoke formed on the surface of the baking tray without sucking the clean air above the air inlet. Meanwhile, the wind shield cover can be used as a handle of the baking tray, so that two purposes are achieved.

The design makes the oil smoke gas flow be limited in the oil smoke circulating air channel to circulate continuously without discharging the oven, and avoids air pollution. However, if the oil smoke is not removed, the concentration of the oil smoke gas flow will gradually increase with the continuous generation of the oil smoke, and finally the external air will be polluted due to diffusion. Therefore, oil smoke elimination treatment is needed, and the oil smoke is eliminated by adopting two modes of oil smoke absorption substances for absorbing oil smoke and oil smoke absorption by a water tank.

And an oil smoke absorption substance is arranged between the first air port and the second air port. The soot absorbing material is typically a solid, porous material such as activated carbon, PP wool, a filter mesh, or the like. A water tank is arranged between the fan and the bottom of the base, and air flow caused by rotation of the fan is blown downwards to the water surface of the water tank. The air flow blowing direction is greatly different from the blowing direction of some air flows only sweeping the water surface in the prior art, and the oil smoke particles in the air flow can be forced to contact the water surface more by directly blowing the air flow downwards to the water surface so as to achieve the cleaning effect.

The sink may be inserted into or pulled out of the base in a pull fashion to facilitate cleaning.
