Integrated stove

Abstract

The invention provides an integrated stove used in families, hotels or restaurants, which comprises a stove and a downward-discharge range hood, wherein a dynamic pressurization air device is arranged between a stove gas inlet valve and a stove air door in order to allow the stove to be easy to ignite and keep gas and air in an optimum mixture ratio; a plurality of smoke-sucking pipes are arranged away from the outside of the upper mouth of a pan; suction mouths slightly incline downwards; the smoke-sucking pipes are connected with an air duct; an oil-fume filter plate is arranged between the air duct and a fan; the tail end of the air duct is provided with an oil collection groove; and an air outlet of the fan is connected with an exhaust pipe to exhaust purified air out from the integrated stove.

Description

technical field [0001] The invention relates to an integrated stove, especially an integrated stove used in a family, a hotel or a restaurant. Background technique [0002] The integrated stove uses the stove to be placed on the countertop of the kitchen cabinet, and there is extra space under the countertop to install a range hood, so it is called an integrated stove. Existing stoves rely on the natural mixing of gas and air in the gas chamber, and the damper design is very strict. If the design is unreasonable, the stove will not be able to ignite. After the fire is turned on, cooking various dishes requires different amounts of heat, such as frying twice-cooked pork. Stirring the fire, stewing nourishing soup requires a slow fire, etc., and the optimal dynamic mixing ratio of gas and air is required to ensure that the gas can be fully burned. The thermal efficiency of ordinary atmospheric gas appliances generally does not exceed 55%. The reason is as described in Chinese...

AI Technical Summary

Problems solved by technology

[0004] The functional features of the above patents all need to be improved. For example, the feature described in Chinese Patent No. 200610022532.0 combines the damper, the power device generated by the gas pressure and the load device. The first problem encountered is that the burning appliance is not easy to ignite. The natural gas pressure is only 2000Pa, driving a turbofan of the same size, the optimal mixing ratio of air and natural gas cannot be solved

The features described in Chinese patents ZL0212079.7 and ZL02234971.5 adopt the principle of micro-aerodynamics, use a fume separator, and the purification rate is only 78%, which does not meet the minimum standard (85%) of environmental protection requirements, and uses a fan greater than or equal to 170 watts The power has not reached the minimum fan power (160 watts) of the national energy-saving certification; the superior arc air inlet is about higher than the pot mouth, even if a fireproof net is added, there is still a safety hazard, because there is oil stains behind the air inlet big cavity

The wind resistance of this large cavity is also very large, resulting in the use of a larger fan power to meet the 99% suction rate
