Description
Technical Field
The invention relates to the technical field of cooker test equipment, in particular to a cooker online performance test bench.
Background
The range is divided into the following parts according to the used gas species: natural gas range, artificial gas range, and liquefied petroleum gas range. The material is divided into: there are cast iron stove, stainless steel stove, enamel stove. The method is divided into the following steps according to cooking range: single-hole range, double-hole range and multi-hole range. The ignition method comprises the following steps: an electric pulse-dissecting ignition stove and a piezoelectric ceramic ignition stove. The installation mode is divided into: desk type range, embedded range. The air inlet mode of embedded cooking utensils has following three kinds, is lower air inlet, goes up air inlet and side air inlet respectively, wherein: (1) The lower air inlet type is used for entering fresh air below the stove to provide oxygen required by full combustion, has the advantages of large fire head and high heat load, and accords with the cooking habit of Chinese family strong fire stir-frying. However, the installation of the embedded lower air inlet cooker needs to pay attention to the fact that a secondary air inlet channel is additionally arranged on a cabinet below the embedded lower air inlet cooker, otherwise, insufficient air causes insufficient combustion of fuel gas, high-concentration carbon monoxide is generated, and even serious consequences such as ignition explosion and panel explosion are caused. (2) The kitchen range with the upper air inlet does not need to be provided with holes on the cupboard, and air enters from the stove head by utilizing the higher stove head. However, the stove has poor effect in practical use, mainly has low thermal efficiency and cannot provide high temperature. (3) side intake type: the air inlet device is arranged at a relatively low temperature region of the panel of the stove, when air in the shell is reduced to form negative pressure by combustion, cold air can be sucked into the shell along the inlet of the air inlet device, sufficient primary air and secondary air required by combustion are provided, the problem of yellow flame is solved, the concentration of carbon monoxide is greatly reduced, leaked gas can be discharged from the air inlet, and even if ignition and deflagration occur in the leaked gas, airflow can be discharged from the air inlet device as soon as possible, so that the internal pressure is quickly reduced, and the burst of a glass panel is avoided. Meanwhile, cold air enters the furnace body through the air inlet device, and the temperature of the table glass is greatly reduced. The heat load of the stove can reach 3,8 kilowatts.
The stove is one of indispensable tools in people's life. However, as the gas source used by the cooker is natural gas, artificial gas or liquefied petroleum gas and the like, if the gas leakage occurs when the cooker is used, safety accidents are directly caused, and the life safety of operators is endangered. Therefore, the kitchen range needs to be detected before leaving a factory, the traditional detection method adopts manual detection, and the problems of low speed, high cost, low working efficiency and the like exist.
