Description

Heat generating device

Technical field

The utility model relates to the field of household appliances, in particular to a heating device for food baking equipment.

Background technique

According to the example of household appliances with baking function on the market, the heat generating device composed of quartz heat pipes is selected. The heating device is generally composed of a quartz tube and a heating wire disposed inside the tube. During operation, the heat generated by the heating wire is dissipated into the furnace cavity through the wall of the quartz tube, thereby baking and heating the food, but due to the tradition The outer casing and/or inner casing of the household appliance is generally made of a metal heat-conducting material, and the heat radiated from the wall of the quartz tube wall away from the food direction is rarely applied to the food body being grilled, and most of the heat is passed through the outer casing. And/or the inner tank is dissipated to the cabinet, which not only reduces the energy utilization and conversion rate, but also causes the aging of the outer casing of the household appliance due to excessive heat transfer, thus reducing the service life and at the same time, during use. There are also safety hazards that can be burned.
