Abstract

The utility model relates to dwelling shared air outlet flue technique territory, especially a dwelling kitchen strong suction type sharing air outlet. The sharing air outlet is characterized in that the utility model comprises a master air outlet and a secondary air outlet which is made of shell body, the secondary air outlet is streamline shaped and arranged in the middle of the master air outlet radial direction. The shared air outlet is free from smoke mixing and air mixing, small in the master and secondary air outlet air flow resistance, wherein the air flow is not easy to be interfered or disordered, air flow extraction force is large, which is suitable for kitchen and toilet of dwelling, especially for dwelling kitchen.

Description

House kitchen is inhaled the shared exhaust duct of formula by force

One, technical field: the utility model belongs to the shared exhaust duct technical field of residential building, and particularly a kind of house kitchen is inhaled the shared exhaust duct of formula by force.

Two, technical background: the design of traditional shared exhaust duct is except that improving on the blast cap of giving vent to anger, in the simplified design of exhaust duct, adopt the major and minor air passage structure of prefabricated concrete moulding usually, the exhaust duct of this structure in use exists exhaust not smooth, air-flow in the major and minor air flue easily produces interferes and disorder, it has not only reduced the speed that air flue rises, and having destroyed the ride comfort of air-flow, cigarette, gas-blowing phenomenon appear scurrying sometimes; The exhaust duct of improved major-minor air passage structure, the height of the secondary air flue that extended, and designed deflector in the exit, airflow state makes moderate progress, but still has the problem of interfering the main airway air-flow during secondary air flue exhaust; The non-return exhaust duct adopts the non-return door part to prevent to fall in the air inlet problem of gas, but have in actual the use that low, the greasy dirt of reliability makes easily that the non-return door is malfunctioning, deficiency such as dimension pipe expense height, air-flow are not smooth; Pressure variable exhausting channel is that local member is set in major and minor air flue, to change main air duct air flow direction and actual internal area size, has effectively prevented to scurry cigarette, gas-blowing phenomenon, but still has had comparatively problem such as complexity of form of structure.

Three, summary of the invention: the purpose of this utility model is a kind of novel shared exhaust duct that designs at existing shared exhaust duct above shortcomings.It utilizes the principles of science and simple structure to overcome the deficiency of existing exhaust duct effectively, not only do not scurry cigarette, gas blowby, and suction force is strong, is suitable for the shared exhaust duct of house kitchen and uses, and also is suitable for the shared exhaust duct in washroom and uses.

This house kitchen is inhaled the shared exhaust duct of formula by force and has been adopted in design and the far different technical scheme of the shared exhaust duct of tradition.It is characterized in that main airway, secondary air flue two parts that it is made of housing form, secondary air flue is the radially middle part that streamlined places main airway.Show that according to hydromechanical principle and experiment outlet secondary air flue vertically upward is consistent with the ascending air direction of main airway, when making progress exhaust, main airway has been produced swabbing action; Main airway is when running into secondary this section of air flue, and fusiform secondary air flue is divided into two the main airway air-flow, unites two into one again after the secondary air flue of airflow passes, because two bursts of air flow rate flow velocity unanimities of separating, the air flow direction antisymmetry has upwards produced swabbing action to secondary air flue so make a concerted effort.

This exhaust duct generally selects for use prefabricated glass fiber mesh or ferro-cement thin-walled technology to make, and wherein secondary air flue also can adopt steel pipe or plastic pipe form to be used for the washroom and use.One section every layer of exhaust duct, low layer is established inspection hole and air inlet port, and roofing is joined the blast cap of existing patented technology.During installation every layer in the building () the plate place utilizes shaggy block butt joint, and establishes the band steel load and puts, after-pouring is in the concrete surface layer of flooring.Aspirating hole adopts the finished product plastic fastening with being connected of kitchen smoke exhaust ventilator or washroom ventilation fan stack, and is easy for installation, both artistic and practical.

This exhaust duct is compared with existing various shared exhaust ducts with tradition, airflow design is rationally smooth and easy, do not scurry cigarette, gas blowby and generation and pour in down a chimney phenomenon, and suction is powerful, the cross section of using airway cross-section that conventional cement mortar thin-walled technology makes and existing exhaust duct roughly the same, use steel pipe or plastic pipe to make the shared exhaust duct of strong suction formula of secondary air flue, its cross section can suit to adopt in high residential building especially less than the cross section of the shared exhaust duct of routine.

Four, description of drawings:

Fig. 1 inhales the main TV structure schematic diagram of the shared exhaust duct of formula by force for the utility model house kitchen.

Fig. 2 is the plan structure schematic diagram of Fig. 1.

Fig. 3 is the main TV structure schematic diagram that secondary air flue adopts the shared exhaust duct of strong suction formula of steel pipe or plastic pipe form.

Fig. 4 is the plan structure schematic diagram of Fig. 3.

Among Fig. 1, Fig. 2, Fig. 3, Fig. 4: 1 housing; 2 secondary air flues, it is a streamlined, and its height is in the radially middle part of main airway 6, and main airway 6 is separated into three air flues, and the secondary air flue 2 among Fig. 3, Fig. 4 is steel pipe or plastic pipe form; 3 aspirating holes, indoor gas advances in the shared exhaust duct of people through this hole during use; 4 pits, it is located on the housing 1; 5 boss, it also is located on the housing 1, and pit 4 and boss 5 are for being connected and fixed device; 6 main airways, it is made of housing 1.

Five, the specific embodiment: Fig. 1, Fig. 2 can be used as a specific embodiment structural representation of the present utility model.Being connected and fixed device is pit 4 and boss 5 structures.

Claims

1, a kind of house kitchen is inhaled the shared exhaust duct of formula by force, it is characterized in that main airway, secondary air flue two parts that it is made of housing form, and secondary air flue is the radially middle part that streamlined places main airway.
