Indoor range hood and operation control method thereof

Abstract

The invention relates to an indoor range hood and an operation control method thereof. The indoor range hood comprises an upper shell body, a fan system and a smoke collecting hood, a top plate is arranged above the smoke collecting hood, the top plate is connected below the upper shell body, a gap is formed between the top plate and the smoke collecting hood, and the indoor range hood is characterized in that the indoor range hood further comprises an air supplement pipe, an air supplement valve is arranged in the air supplement pipe, one end of the air supplement pipe communicates with the external space of a kitchen, the other end of the air supplement pipe communicates with the gap between the top plate and the smoke collecting hood, and the side face of the smoke collecting hood or / and the top plate is / are provided with an air outlet assembly which communicates with the gap. Compared with the prior art, the indoor range hood and the operation control method thereof have the advantages that fresh air can be actively introduced from the external space of the kitchen, and the fresh air and hot air near a stove easily form an outer surrounding flow field, so that the interferenceto the flow field near the range hood when doors and windows are opened and closed and other people walk is reduced, the face blowing effect can be provided for a user, and the use experience is improved.

Description

technical field [0001] The invention relates to an indoor range hood and an operation control method thereof. Background technique [0002] Most of the current high-rise residences adopt the centralized smoke exhaust method. The indoor range hood is connected to the public flue through a smoke pipe and a check valve, so that the oil fume in the kitchen is discharged into the public flue through the indoor range hood through the smoke pipe. However, the cooking habits of the Chinese people with cooking fume and the current situation of large air volume and high air pressure pursued by the existing range hoods make the air volume and pressure in the public flue large, so the problem of poor smoke exhaust often occurs. In addition, many users have the habit of closing the kitchen doors and windows when using range hoods. When the doors and windows are closed, vacuuming is likely to occur in the kitchen, resulting in increased inlet resistance. The indoor range hood flow rate ca...

Problems solved by technology

However, the cooking habits of the Chinese people with cooking fume and the current situation of large air volume and high air pressure pursued by the existing range hoods make the air volume and pressure in the public flue large, so the problem of poor smoke exhaust often occurs

In addition, many users have the habit of closing the kitchen doors and windows when using range hoods. When the doors and windows are closed, vacuuming is likely to occur in the kitchen, resulting in increased inlet resistance. The indoor range hood flow rate cannot reach the target flow rate. Doors and windows are also difficult to open; on the other hand, many users feel that the kitchen is hot in summer, and kitchen air conditioners and coolers generally blow air from the top and circulate internally, which easily interferes with the flow field, resulting in poor oil suction effect and cold on the back of the head. , It is also easy to make the kitchen air conditioner and the fan blade of the cooling fan themselves polluted by the circulating oil fume air. After a period of use, it is difficult to clean up and there are peculiar smells, which affect the experience, and then affect the user experience and word of mouth.
