Specifically, the air inlet assembly 100 may be disposed on the cooktop 200 of the cooker. When the oil fume suction device is not activated, the air duct body 20 can be controlled to be in a low position, that is, the upper opening of the air duct body 20 is not higher than the countertop of the cooktop 200. When the oil fume suction device is activated, the air duct body 20 can be controlled to rise, thereby reducing The distance between the small air duct body 20 and the cooking utensils is to improve the oil fume absorbing effect of the oil fume absorbing device.

Further, the combined device with a range fume absorbing device and a cooker also includes a cooker and a cooker fume absorbing device. The cooker includes a cooktop 200. The cooktop 200 is provided with an installation opening 210, and the air inlet assembly 100 is provided in the installation opening 210. The oil fume suction device is not activated, and the air duct body 20 does not extend out of the installation opening 210, thereby avoiding the collision between the cookware and the air duct body 20 caused by the user in the process of taking the cookware. It is used to control the air duct body 20 to extend from the installation opening 210 when the oil fume absorbing device is activated, so that the upper mouth of the air duct body 20 rises, thereby achieving a better oil fume absorbing effect.

What needs to be understood here is that most of the existing integrated stoves have the function of absorbing oil fume, and some of them are affected by factors such as space or decoration style, and the smoking port is set in the stove and the top surface of the stove is set flush with the surface of the stove. However, because the smoking port is much lower than the cooking appliance on the side at this time, the oil fume that originally flowed upward will be adsorbed downward, and the oil fume will be scattered more, which causes the effect of oil fume absorption to be less than ideal.

The air intake module of the present application will be described in detail below with reference to the drawings and in conjunction with exemplary embodiments.

As shown in Figures 12 to 17, the first exemplary embodiment of the present application provides an air intake module, which includes an air intake hood 1, a lever-type lifting mechanism, and a trigger control mechanism.

The arm section, and the locking elastic member 110 is arranged to be able to keep the air intake hood 1 at the top dead center position. In other words, when the air intake hood 1 is at the top dead center position, the locking elastic member 110 locks the air intake hood 1, and the locking elastic member 110 may be different types of elastic members such as a tension spring or a gas spring.

In an embodiment, the trigger control mechanism can be manually controlled and includes the button outer bracket 120 and the button body. Among them, the button outer bracket 120 is fixedly arranged and formed with a button limiting groove 12a, the button body is elastically pressable and arranged in the button outer bracket 120, and the button body includes an outer pressing plate 130 and a button driving part capable of interacting with the power arm section. 140 and the button limiting portion 15 extending into the button limiting groove 12a. When the outer pressing plate 130 is manually pressed, the button driving unit 140 can be driven to move down synchronously. By extending the button limiting portion 15 into the button limiting groove 12a, the button limiting portion 15 can only slide in the groove, thereby The vertical movement range of the button body is limited.

The following explains how to manually control the above trigger control mechanism to raise the air intake hood 1 to the top dead center position and how to reset the air intake hood 1 to the bottom dead center position in conjunction with the embodiments in the drawings.

Specifically, in the illustrated embodiment, the bottom wall of the button outer bracket 120 is connected with a positioning column 12b, and the button body further includes a button spring 16 sleeved on the positioning column 12b, and the bottom end of the button spring 16 abuts against the outside of the button. The bottom wall and top of the bracket 120 abut against the outer pressing plate 130.

When the air intake hood 1 is raised from the bottom dead center position in FIG. 13 to the top dead center position in FIG. 14, the outer pressing plate 130 can be pressed down to drive the button driving part 140 to move down, and the button driving part 140 moves down During the process, the first pivoting trigger portion 3a and the second pivoting trigger portion 4a are simultaneously crimped, and since the inner end of the first transmission arm 3 and the inner end of the second transmission arm 4 form a meshing transmission connection, the first The power arm section and the second power arm section can simultaneously pivot downward so that the first resistance arm section and the second resistance arm section pivot upward at the same time, and are simultaneously driven by the first support link 7 and the second support link 8 The third resistance arm section and the fourth resistance arm section pivot upwards, thereby raising the air inlet hood 1 from the bottom dead center position to the top dead center position.

In the above process, when the pressing force acting on the outer pressing plate 130 is removed, the outer pressing plate 130 will move upward due to the rebound effect of the button spring 16, and under the limit action of the button limit groove 12a, it can make When the outer pressing plate 130 moves up to the initial position, it stops.

In addition, in the illustrated embodiment, the locking elastic member 110 includes a first tension spring and a second tension spring. Wherein, the outer end of the first tension spring is fixedly connected to the second resistance arm section and the inner end is fixedly connected to the first pivot bracket 9, and the inner end of the first tension spring is higher than the second fulcrum of the second transmission arm 4部4b is set up.

In addition, both the first tension spring and the second tension spring always maintain a stretched state.

With the above structure, when the air intake hood 1 is raised to the top dead center position, the second resistance arm section receives the first pulling force of the first tension spring on it, and the first pulling force has a relatively large vertical component force. And the direction is upward. In the same way, the third resistance arm segment is subjected to the second pulling force of the second tension spring, and the second pulling force has a relatively large vertical component and an upward direction. At this time, under the combined action of the first pulling force and the second pulling force, the air intake hood 1 can always be maintained at the top dead center position.

When the air intake hood 1 is lowered from the top dead center position in FIG. 14 to the bottom dead center position in FIG. 13, the air intake hood 1 can be directly pressed down to the bottom dead center position. At this time, although the first tension spring and the second tension spring still generate tension on the second resistance arm segment and the third resistance arm segment, respectively, the tension spring follows the lever-type transmission arm to pivot to a certain angle, making The spring tension is no longer sufficient to overcome the force generated by the air intake cover 1 on the first support link 7 and the second support link 8 to drive the transmission arm to pivot, so the air intake cover 1 can be maintained at the bottom dead center position.

In an embodiment, when the trigger control mechanism triggers the lever pivoting action, the length of the power arm between the trigger control mechanism and the lever fulcrum can be set to be less than the length of the resistance arm between the air intake hood 1 and the lever fulcrum. . At this time, a small stroke on the power side of the transmission arm can be used to obtain a large stroke on the resistance side. For example, in the illustrated embodiment, the air inlet hood 1 can be moved upward by pressing the button body down for a short distance. Larger distance, so it is easier to achieve control.

In addition, the main bracket 2 may be provided with a positioning bracket 2a. At this time, the aforementioned pivot bracket can be fixed on the main bracket 2, and the lever fulcrum of the lever-type transmission arm can be pivotally connected to the positioning bracket 2a and the pivot bracket. between. The positioning bracket 2a can be provided with a bracket limiting portion 2b, and the button body can also be provided with a body limiting slot. At this time, the bracket limiting portion 2b extends into the body limiting slot, which can also limit the vertical stroke of the button body .
