Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The utility model discloses an inward-opening side-suction type smoke exhaust ventilator, which is shown in fig. 1 to 4, and comprises a machine shell 1, wherein a suction port 101 is formed at the front lower part of the machine shell 1, the upper end of the machine shell 1 is connected with a fan cover 2, an impeller of the smoke exhaust ventilator is arranged in the fan cover 2, and an air outlet is formed at the upper end of the fan cover 2.

As shown in fig. 1 to 4, the suction port 101 is correspondingly provided with a damper 4 for opening and closing the suction port 101, the lower end of the damper 4 is hinged with the lower end of the casing 1, that is, the pivot point of the damper 4 is located at the lower end of the damper 4, so that the damper 4 can swing back and forth, as shown in fig. 1 and 2, the damper 4 has an open position relative to the suction port 101, in which the damper 4 is located inside the casing 1, in other words, the damper 4 is an inwardly opened damper, the damper 4 swings toward the inside of the casing 1 to open the suction port 101, an oil cup 5 is provided at the lower side of the lower end of the casing 1, the oil cup 5 can be connected to the lower end of the casing 1 by means of a hanging buckle, and the lower end of the damper 4 is located correspondingly above the oil cup 5.

As shown in fig. 5, the casing 1 may be mounted by a wall, the suction inlet 101 is located at the rear upper side of the kitchen range, when cooking is performed, food in the cooker on the kitchen range generates oil smoke, the impeller of the kitchen range operates to make the suction inlet 101 form negative pressure, so that the oil smoke air flow is sucked by the suction inlet 101 to flow backward and upward and enter the suction inlet 101. As shown in fig. 5, since the damper 4 swings open inwardly (i.e., backward), and the lower end of the damper 4 is located above the corresponding oil cup 5, when the range hood is operated, if oil dirt accumulates in front of the damper 4 or behind the damper 4, the oil dirt will flow down the damper 4 to the lower end of the damper 4, so that the oil dirt on the damper 4 will only drop into the oil cup 5, and since the lower end of the damper 4 is hinged with the lower end of the housing 1, the lower end of the damper 4 is closer to the oil cup 5, thereby facilitating collection of the oil dirt. Therefore, the side-suction type smoke exhaust ventilator with the inner opening door can prevent oil stains on the air door from dripping on a kitchen cabinet table surface, a kitchen range or food, and is beneficial to cleaning and sanitation.

Further, as shown in fig. 1 to 4, an electric push rod 42 for driving the air door 4 to swing is disposed in the casing 1, the electric push rod 42 includes a telescopic rod 421 and a casing 422, an inner end of the telescopic rod 421 is slidably disposed in the casing 422, a swing arm 41 is fixedly connected to a rear of the air door 4, a front end of the swing arm 41 can be adhered to a lower portion of a rear of the air door 4, the telescopic rod 421 is hinged to the swing arm 41, specifically an outer end of the telescopic rod 421 is hinged to a rear end of the swing arm 41, the casing 422 is hinged to the casing 1, and specifically an upper end of the casing 422 is hinged to a push rod support 43 mounted on a rear inner wall of the casing 1. Then, when the telescopic rod 421 is extended, the telescopic rod 421 pushes down the rear end of the swing arm 41, thereby swinging the damper 4 backward to be opened; when the telescopic rod 421 is retracted, the telescopic rod 421 drives the air door 4 to swing forwards to close the air suction port 101. Through setting up electric putter 42 for air door 4 can be opened and closed through electric mode, is favorable to facilitate the use.

Further, as shown in fig. 1 to 4, the front upper portion of the casing 1 is provided with a panel 3 disposed obliquely downward, specifically, the upper end of the panel 3 is located in front of the lower end of the panel 3, and as shown in fig. 3 and 4, the damper 4 has a closed position with respect to the suction port 101, in which the front face of the damper 4 is disposed in the same plane as the front face of the panel 3. Specifically, the wall of the front portion of the casing 1 is provided obliquely downward, and the panel 3 is abutted against the front side of the wall mounted to the front portion of the casing 1, and accordingly, the panel 3 is also obliquely downward. When the air door 4 is in the closed position, the front of the air door 4 is arranged in the same plane with the front of the panel 3, so that the range hood is beneficial to having a smooth visual effect and cleaning the air door 4 conveniently. As shown in fig. 5, when the range hood works, the front (i.e. the outside) of the air door 4 is mainly contacted with the fume flow, so that the rear area of the air door 4 has less greasy dirt, and a user can conveniently clean the front of the air door 4 when the air door 4 is closed, so that the air door 4 is easier to keep clean. As shown in fig. 6, since the inner face (i.e., the lower face) of the prior art outward opening door 98 is in contact with the flow of the cooking fumes, although there is little oil stain on the outer face of the outward opening door 98, the inner face of the outward opening door 98 will have relatively more oil stain, and the inner face of the outward opening door 98 will not face the user and be difficult to clean, whether the outward opening door 98 is in the closed position or the open position. As shown in fig. 4, when the damper 4 of the present utility model is in the closed position, the oil dirt on the damper 4 can still flow down the damper 4 to the lower end of the damper 4 and then drop into the oil cup 5, thereby facilitating the maintenance of the range hood and kitchen clean.

Further, as shown in fig. 2 and 4, the back plate 7 is disposed in the casing 1, the back plate 7 is disposed at the rear side of the air door 4, an oil filter screen 6 is disposed between the upper end of the back plate 7 and the rear side of the face plate 3, and the oil filter screen 6 is disposed at the upper side of the air door 4, as shown in fig. 5, so that the oil fume air flow needs to flow to the impeller through the oil filter screen 6 and then be discharged upwards, and oil in the oil fume air flow can adhere to the oil filter screen 6, so that the oil stains accumulated on the impeller can be reduced, and the smoke exhaust ventilator can discharge smoke with less oil. Since the oil filter 6 is provided between the upper end of the back plate 7 and the rear surface of the face plate 3, when the damper 4 is closed, the oil filter 6 is not visible from the outside, which is advantageous in terms of beauty. When the damper 4 is opened, the oil filter screen 6 can be detached for cleaning. When the damper 4 is closed, the oil dirt dropped from the oil filter 6 is caught by the rear surface of the damper 4, and the oil dirt flows down along the rear surface of the damper 4 into the oil cup 5.

Further, the air door 4 is set to be a glass air door, which is beneficial to making the surface of the air door 4 smooth, is beneficial to oil dirt flowing down to the lower end of the air door 4 along the air door 4, and is convenient for a user to clean the air door 4 by using rags and detergent.
