Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
As shown in Figure 1, a kind of pressure-balancing type kitchen twin shafts is concentrated air-supply smoke evacuation system device, comprise smoke evacuation well 2, be positioned at unpowered blast cap 4 and multiple kitchen exhaust arm 13 at smoke evacuation well 2 tops, the equal one end of each kitchen exhaust arm 13 arranges to prevent that with smoke evacuation well 2 UNICOMs oil smoke from pouring in down a chimney smoke blowing through flap valve 14, the other end and smoke exhaust ventilator 12 UNICOM respectively that is positioned at these kitchen exhaust arm 13 place floors, it also comprises the new wind blowing shaft 1 that parallel smoke evacuation well 2 arranges, be positioned at the new wind main entrance 5 of new wind blowing shaft 1 bottom, the inner new wind air compensation device 3 in the new wind air intake 6 in multiple kitchens and kitchen, new wind main entrance 5 is used for introducing outdoor air with new wind blowing shaft 1 UNICOM, the quantity setting of the corresponding multiple kitchen exhaust arms 13 of the new wind air intake 6 in kitchen, one end of the new wind air intake 6 in each kitchen is connected with new wind blowing shaft 1, the other end of the new wind air intake 6 in each kitchen is connected with the inner new wind air compensation device 3 in kitchen of the new wind air intake 6 place floors in this kitchen.
Pressure-balancing type kitchen twin shafts shown in the utility model concentrates air-supply smoke evacuation system device from multilayer and Kitchen in High Rise Apartment ventilation angle, by adding new wind well in multilayer or Kitchen in High Rise Apartment smoke shaft side, new wind well, kitchen, exhaust air shaft have just formed a reversed return type pipe network system like this.Bottom resident family send new wind apart from short, smoke evacuation distance; Top layer user send new wind distance, and smoke evacuation distance is short, can thoroughly solve the unbalanced phenomenon of air draft, possesses many-sided functions such as different floor gap balance smoke-exhaustings, newly wind is provided and delivered, pollution cuts off, kitchen heating air-conditioner is energy-conservation.
As shown in Figures 2 and 3, in the present embodiment, the inner new wind air compensation device 3 in each kitchen comprises new wind secondary air channel 8, be arranged on small-sized axial flow fan 9 in new wind secondary air channel 8, be arranged at the new wind air supply grille 10 in kitchen range top front and be close to the verge board 11 that lampblack absorber 12 arranges, and the two ends of the new wind secondary air channel 8 respectively new wind air intake 6 in kitchen and the new wind air supply grille 10 of this floor of UNICOM arrange that outdoor new wind is caused to kitchen range top place.In the time that negative pressure is enough large, new wind arrives new wind air supply grille 10 places by the new wind air intake 6 in kitchen, new wind secondary air channel 8; If when negative pressure is inadequate, can be arranged on by startup the outside small-sized axial flow fan switch open small-sized axial flow fan 9 of new wind air compensation device, make its pressurization that power is provided, thereby new wind can effectively arrive new wind air supply grille 10 places by the new wind air intake 6 in kitchen, new wind secondary air channel 8.Conventionally in the time of culinary art, in order to be effective, can keep small-sized axial flow fan 9 one direct-opens until culinary art finishes.
Particularly, in the use procedure of twin shafts smoke evacuation system, first ensure that in kitchen, smoke exhaust ventilator 12 is normally opened, kitchen door and kitchen window keep relative closure as far as possible simultaneously, make the high negative pressure of indoor formation, in the time that indoor negative pressure is enough large, new wind secondary air channel 8 is connected, the new wind entrance 6 in kitchen that leads to new wind well will automatically be introduced outdoor new wind under suction function, arrive new wind air supply grille 10 via new wind secondary air channel 8 place branch roads, and the new wind in a organized way of introducing sprays via air supply grille 10.This new wind forms air curtain on the one hand between oil smoke and personnel, by isolated to oil smoke and human body respiration district, itself and lampblack absorber left and right verge board form the form of similar laboratory hood on the other hand, lampblack absorber is isolated within the scope of air draft and is got rid of, directly extracted by lampblack absorber and be discharged to outdoor via kitchen exhaust arm 13 and smoke evacuation well 2.
Twin shafts smoke evacuation system shown in the utility model becomes kitchen inorganization and mends wind into mending in a organized way wind, also solve simultaneously and when inorganization is oozed energy consumption problem that wind brings and hot uncomfortable problem, improve oil smoke and cut off efficiency, send new wind can also in this external cooking process personnel respiratory region, realize kitchen negative-pressure inlet, fixed point dispensing, and the air outlet that new wind air supply grille 10 is flap type, user of service can regulate arbitrarily wind direction as required.
Consider that the indoor negative pressure of highrise building is generally not enough, therefore be provided with small-sized axial flow fan 9 in new wind secondary air channel 8, when use, can keep small-sized axial flow fan 9 always in opening, make its pressurization that power is provided, thereby new wind can effectively arrive new wind air supply grille 10 places by the new wind air intake 6 in kitchen, new wind secondary air channel 8, can the unbalanced phenomenon of more efficiently solution highrise building air draft, make different floor gap balance smoke-exhaustings, and possess many-sided functions such as new wind is provided and delivered, pollution cuts off, kitchen heating air-conditioner is energy-conservation.
In the present embodiment, the new wind entrance in kitchen (6) be positioned at apart from the kitchen range top recently and on the exterior wall of easy construction so that new wind air compensation device resistance minimum; In the installation process of the new wind air compensation device in kitchen, for reduce the duct length of new wind air compensation device as far as possible, general, when the interior decoration of kitchen, locate a reserved rectangle air port at kitchen range top electromagnetic oven or gas furnace near personnel, for new wind air supply grille 10 is installed.Meanwhile, because new wind air supply grille 10 is positioned at kitchen range top front end, temperature is higher comparatively speaking herein, and easily directly contacts with burning things which may cause a fire disaster, therefore new wind air supply grille 10 entirety adopt fire and heat endurance incombustible material to make.
In addition, consider owing to may having some impurity or large-scale particulate in outdoor air, in the time that it pollutes the new wind air compensation device of partition-type by microkinetic, long-term use easily causes the obstruction of new wind air compensation device, therefore in the present embodiment, be also provided with air filter 7 between the new wind entrance 6 in kitchen and new wind secondary air channel 8, air filter 7 one end are connected with new wind entrance 6, the other end is connected with new wind secondary air channel 8, for filtering the bulky grain of new wind.
The above-mentioned description to embodiment is can understand and apply the utility model for ease of those skilled in the art.Person skilled in the art obviously can easily make various amendments to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art are according to announcement of the present utility model, and not departing from improvement and the amendment that the utility model category makes all should be within protection domain of the present utility model.
