Description

Submerged range hood

Technical Field

The invention relates to the technical field of kitchen electricity, in particular to a submersible range hood.

Background

Along with the development of social economy, the living standard of people is also growing day by day. Cooking is closely related to life, and therefore, people have higher and higher requirements on kitchen environment. The smoke absorbing effect of the range hood and the use tools necessary for kitchens is a main factor considered by people, so that various forms of range hoods appear on the market, and particularly, the hidden range hood with a downward air inlet is a product which is hot in the future.

In the related art, the common range hoods on the market have three types, namely a top suction type range hood, a side suction type range hood and a submerged type range hood. The ceiling-mounted range hood is usually installed in order to better collocation cupboard, and its collection hood upper surface is flat with the cupboard bottom surface subsides, and consequently the mounted position is generally higher, but its air intake is far away from the top of a kitchen range, and smoking effect is relatively poor, in order to improve smoking effect, just needs increase motor power, consequently causes the cost to rise, defects such as noise increase, in addition, the ceiling-mounted range hood is higher because the mounted position, and the user takes place to bump the phenomenon comparatively easily when cooking. Side suction type range hood, the distance of air intake and top of a kitchen range has been drawn close, the smoking effect has been improved, thereby it is less to lead to its collection smoke chamber overall dimension because the size of its wind cabinet system is great, consequently, the wind cabinet system adopts overhead mode mostly, partial or holistic wind cabinet system is in collection smoke chamber top so appearing, can't match with the cupboard when leading to changing new quick-witted, namely the user can not carry out the variety selection of cigarette machine, in addition, the side suction machine becomes certain contained angle with the top of a kitchen range, it is poor to hold together the cigarette effect, cause the oil smoke to escape very easily. Latent formula range hood, through descending the air intake in order to realize that the negative pressure district moves down to solved the problem that the distance is too far away of air intake and top of a kitchen range, but when the oil smoke rises in the culinary art process, because the oil smoke escapes outwards seriously and leads to the unsatisfactory smoking effect, in addition, the width of the box of most latent formula range hood is all around 430mm in the left and right sides direction, and the width of traditional cupboard in the left and right sides direction is around 400mm, therefore the user is difficult to be collocated with traditional cupboard when needing to change over new to the cigarette machine.
