Abstract
A double air inlet longitudinal exhaust way is provided, which has an exhaust way outer casing, and a longitudinal airflow passage arranged in the exhaust way outer casing, wherein the longitudinal airflow passage is divided by a small screen into a large longitudinal airflow passage and a small longitudinal airflow passage, and the small longitudinal airflow passage has a sealed lower end and an opened upper end and is communicated with the large longitudinal airflow passage. The upper part of the exhaust way outer casing is provided with a large air intake, which receives wind send by a fume exhaust fan or a discharge fan to the airflow passage. The exhaust way outer casing is provided with a small air intake, the other end of a small air induction conduit connected externally with the small air intake is exposed directly on the ground of a kitchen or a toilet. The air collected by the small air induction conduit from a kitchen or a toilet passes through the small longitudinal airflow passage uninterruptedly and slowly by draught formed by the internal pressure difference of a longitudinal exhaust system, and passes into the large longitudinal airflow passage and is exhausted into the air from a roof together. Therefore, the product can improve uninterruptedly the air quality of the kitchen or the toilet, and improve the utilization ratio of the longitudinal exhaust way.
Description
Technical field
The utility model step and a kind of dwelling house are vertically concentrated vertical exhast duct of exhaust system
Back of the body border technology
Vertical air inlet port of exhast duct operated by rotary motion in the prior art, this air inlet port is accepted the air-supply of smoke exhaust ventilator or exhaust fan.In order to prevent that the gas in vertical exhast duct from blowing back in kitchen or the washroom by above-mentioned air inlet port, this air inlet port is in when not exhaust closes and sealing state, and this moment is exhast duct and the complete isolation in kitchen or place, washroom vertically.Therefore, existing vertical exhast duct can only rely on this simple function of exhaust mechanical air supply, has certain scarce limit.
The utility model content
The purpose of this utility model provides a kind of vertical efficiently exhast duct.
The of the present utility model pair of vertical exhast duct of air inlet port has the air channel shell, is arranged at the longitudinal air flow passage in the shell of air channel, is provided with small baffle in the longitudinal air flow passage.Described small baffle is separated into big longitudinal air flow passage and little longitudinal air flow passage to the longitudinal air flow passage.Little longitudinal air flow passage lower end sealing, upper end are opening and link to each other with big longitudinal air flow passage.Have big air inlet port in the air channel shell upper, big air inlet port links to each other with big longitudinal air flow passage, has little air inlet port at the air channel outer casing bottom, and little air inlet port links to each other with little longitudinal air flow passage.Described little air inlet port is circumscribed with little air inlet pipe, the directly outer ground that is exposed at kitchen or washroom of the other end of little air inlet pipe.Smoke exhaust ventilator accepted by big air inlet port or exhaust fan is blown to big longitudinal air flow passage.The air that the kitchen of being collected by little air inlet pipe or washroom are drained in the draft that little air inlet port forms by vertical exhaust system internal pressure differences incessantly lentamente enters in the big longitudinal air flow passage by little longitudinal air flow passage and together enters the atmosphere from the roof.
Compare with aforementioned like product, vertical exhast duct of the present utility model still can be realized the air-supply function of accepting smoke pumping or exhaust fan identical with existing product, but this product can also improve kitchen or washroom air quality simultaneously incessantly, improves the utilization ratio of vertical exhast duct.
Content of the present utility model further illustrates with the following Examples.
Description of drawings
Fig. 1 is the front view of vertical exhast duct among the embodiment;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is Fig. 1 stereogram, wherein;
(1) air channel shell; (2) longitudinal air flow passage; (3) small baffle; (4) big longitudinal air flow passage; (5) little longitudinal air flow passage; (6) big air inlet port; (7) little air inlet port; (8) little air inlet pipe.
The specific embodiment
Shown in Fig. 1-4, the vertical exhast duct of two air inlet ports in the present embodiment has air channel shell 1, is arranged at the longitudinal air flow passage 2 in the air channel shell 1, is provided with small baffle 3 in longitudinal air flow passage 2.Described small baffle 3 is separated into big longitudinal air flow passage 4 and little longitudinal air flow passage 5 to longitudinal air flow passage 2.Little longitudinal air flow passage 5 lower ends sealings, upper end are opening and link to each other with big longitudinal air flow passage 4.Have big air inlet port 6 on air channel shell 1 top, big air inlet port 6 links to each other with big longitudinal air flow passage 4, has little air inlet port 7 in air channel shell 1 bottom, and little air inlet port 7 links to each other with little longitudinal air flow passage 5.Described little air inlet port 7 is circumscribed with little air inlet pipe 8, the directly outer ground that is exposed at kitchen or washroom of the other end of little air inlet pipe 8.Smoke exhaust ventilator accepted by big air inlet port 6 or exhaust fan is blown to big longitudinal air flow passage 4.The air that the kitchen of being collected by little air inlet pipe 8 or washroom are drained in the draft that little air inlet port 7 forms by vertical exhaust system internal pressure differences incessantly lentamente enters in the big longitudinal air flow passage 4 by little longitudinal air flow passage 5 and together enters the atmosphere from the roof.
Claims (4)
1, a kind of pair of vertical exhast duct of air inlet port, has the air channel shell, be provided with the longitudinal air flow passage in the shell of described air channel, it is characterized in that being provided with small baffle in the longitudinal air flow passage, the longitudinal air flow passage is separated into big longitudinal air flow passage and little longitudinal air flow passage.
2, according to the described vertical exhast duct of claim 1, it is characterized in that, described little longitudinal air flow passage lower end sealing, upper end open also is connected with big longitudinal air flow passage.
