Abstract

The utility model relates to an improved vertical cooker hood. The utility model comprises a casing, a motor, an impeller and an air guide spiral casing, and a centrifugal fan is formed by that the motor and the impeller are arranged in the air guide spiral casing. The utility model is characterized in that the bottom of the air guide spiral casing is provided with an oil draining hole, and the oil draining hole is provided with a U-shaped oil flowing pipe. Because the utility model adopts the U-shaped oil flowing pipe, the cooking fume accumulated in the U-shaped oil collecting pipe can effectively seal the oil draining hole of the air guide spiral casing, the oil draining hole is prevented from leaking air, the cooking fume exhausting work efficiency of the centrifugal fan is increased, the cooking fume is drained into the oil collecting groove through the U-shaped oil flowing pipe, the cooking fume is prevented from dripping and splashing, and the sanitation is high.

Description

A kind of improved vertical smoke exhaust ventilator

The utility model relates to a kind of smoke exhaust ventilator, and particularly a kind of vertical smoke exhaust ventilator belongs to the improvement of household electrical appliance.

The interior tobacco tar of the wind-guiding spiral case of existing vertical smoke exhaust ventilator generally all leads to its draining hole and directly splashes in the oil groove, the oil extraction mode of this structure, the draining hole leaks gas in the centrifugal blower course of work, reduced the operating efficiency of centrifugal blower oil suction cigarette, simultaneously because draining pitch-row oil groove has certain height, tobacco tar splashes into and splashes easily in the oil groove and be scattered out, influences health.

The purpose of this utility model provides a kind of smoke pumping high efficiency, and the improved vertical smoke exhaust ventilator of clean hygiene.

The utility model comprises housing, motor, impeller and wind-guiding spiral case, and motor, impeller are arranged on forms centrifugal blower in the wind-guiding spiral case, it is characterized in that wind-guiding spiral case bottom has the draining hole, and this place, draining hole is provided with the U-shaped flowline.

The utility model is owing to adopt the structure of U-shaped flowline, the tobacco tar of U-shaped flowline inner accumulated effectively seals up the draining hole of wind-guiding spiral case, avoided the gas leakage in draining hole, improve the lampblack-pumped operating efficiency of centrifugal blower greatly, tobacco tar enters oil trap by the U-shaped flowline, also avoided oil smoke to drip spilling of causing, more clean, sanitary.

Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged diagram of Fig. 1 U-shaped flowline;

As Fig. 1-shown in Figure 2: the utility model comprises housing (1), motor (2), impeller (3) and wind-guiding spiral case (4), motor (2), impeller (3) is arranged on forms centrifugal blower in the wind-guiding spiral case (4), wherein wind-guiding spiral case (4) bottom has draining hole (41), and the pipeline (42) that draining hole (41) stretch out and are formed with certain-length, for the draining hole (41) of avoiding wind-guiding spiral case (4) leaks gas in the centrifugal blower course of work, influence the operating efficiency of centrifugal blower, and spilling of causing when avoiding tobacco tar directly to splash into oil trap (or catchment cup), place, draining hole is provided with U-shaped flowline (5), and an end of U-shaped flowline (5) is nested with on the pipeline (42) of draining hole (41).For making things convenient for the interior tobacco tar discharging of U-shaped flowline (5), oil trap (71) has been made in the corresponding U-shaped flowline of base plate (7) (5) position of housing (1), the opening of this oil trap (71) be positioned at U-shaped flowline (5) other end under, make the too much tobacco tar of U-shaped flowline (5) inner accumulated in time lead to catchment cup by this oil trap (71) easily.

Claims

1, a kind of improved vertical smoke exhaust ventilator, comprise housing (1), motor (2), impeller (3) and wind-guiding spiral case (4), motor (2), impeller (3) are arranged on forms centrifugal blower in the wind-guiding spiral case (4), it is characterized in that wind-guiding spiral case (4) bottom has draining hole (41), this place, draining hole is provided with U-shaped flowline (5).

2, according to the described improved vertical smoke exhaust ventilator of claim 1, it is characterized in that the pipeline (42) that the draining hole (41) of above-mentioned wind-guiding spiral case (4) stretches out and is formed with certain-length, an end opening of U-shaped flowline is nested with on this pipeline (42).

3,, it is characterized in that oil trap (71) has been made in the corresponding U-shaped flowline of base plate (7) (5) position of above-mentioned housing (1) according to claim 1 or 2 described improved vertical smoke exhaust ventilators.
