A range hood oven uses downward internal ventilation to extract steam and smoke from the oven hob, making it a good option for kitchens without space for a vent hood. However, it requires access to the outside for ventilation and may draw heat away from the burners.
A range hood oven is a type of oven that uses downward internal ventilation to exhaust steam and smoke from the oven hob. This is typically done in contrast to the use of vents which are mounted to the cooking surface of an oven range. Downdraft installations are often preferred by people who have a kitchen that features an oven as part of an island or for those who may not have room for a vent hood over the oven. A range hood oven may take up less space than other types of ovens, but there are some downsides to choosing a draft ventilation system.
Also called a stovetop, a countertop oven usually consists of an oven built with a stovetop on top. Ovens with hobs are often installed in locations where a vent hood can be placed over the oven to provide adequate ventilation for the cooker. This ventilation can be used to extract steam and smoke from a kitchen, making cooking on a stovetop more comfortable, or to remove oil particles from the air during frying. In kitchens where there may not be enough space for a vent hood, however, a downdraft oven may be a better option.
A range hood oven typically works by pulling air from the hob area of an oven. The name of this type of oven derives from the fact that the air is conveyed into the oven itself, rather than into a hood and then discharged outside. How this downward ventilation takes place depends on the model of oven chosen and the features provided. Some ovens have a vent right on the hob surface, while other models have a mechanism that lifts a vent off the cooking zone during use.
While a downdraught furnace may eliminate the need for a vent hood, the air moved through the downdraft system still needs a place to vent. This usually requires access from the downdraft mechanism to the outside of a house or kitchen and may require special construction or renovation to accommodate. Ovens that use a vent on the cooktop surface may also produce less heat from the cooking surface since the venting process can actually work to draw heat away from the burners. This makes downdraft ovens that have concealed vents preferable for most users, although they can also be more expensive.
