For convenience of description, in this specification, "front", "rear", "left", "right", "up" and "down" refer to directions of the extractor hood relative to a user when in use.

The grease collecting device 2 comprises a first grease collecting box 21, a push plate 22, a driving mechanism 23 for driving the push plate 22, a transmission mechanism 24 for transmitting the force of the driving mechanism 23 to the push plate 22, a grease leaking nozzle 25 and a second grease collecting box 26, wherein the second grease collecting box 26 can be a grease can. The first oil collecting box 21 is open at the top and is arranged at the inner side of the bottom of the shell 1 to form a hidden structure. The oil leakage nozzle 25 is arranged at the bottom of the first oil collecting box 21, the oil leakage nozzle 25 extends to the lower part of the bottom of the shell 1, the second oil collecting box 26 is detachably connected with the oil leakage nozzle 25, and when the range hood works normally, the second oil collecting box 26 is not connected with the first oil collecting box 21 generally.

The push plates 22 are provided at both left and right ends (both ends in the longitudinal direction) in the first oil collecting box 21 to be linearly movable in the left and right directions in the first oil collecting box 21, and the oil leaking nozzle 25 is provided in the middle of the first oil collecting box 21. The driving mechanism 23 employs a motor, and the motor is disposed outside the first oil collecting box 21. The two push plates 22 are connected with the driving mechanism 23 through a transmission mechanism 24. In this embodiment, the transmission mechanism 24 is a screw rod, two ends of the screw rod are respectively connected with the push plate 22 by threads, and one end of the screw rod extends out of the first oil collecting box 21 and is connected with an output shaft of the motor. The screw rod is provided with a first thread section 241 and a second thread section 242 which respectively extend in the length direction (left-right direction) of the first oil collecting box 21, the screw directions of the two thread sections are opposite, each thread section extends from the end part (left end or right end) in the length direction of the first oil collecting box 21 to the middle, and the two push plates 22 are respectively in threaded connection with one of the thread sections. Thus, when the motor is operated, the screw rod rotates, and the two push plates 22 move in opposite directions, i.e., the two push plates 22 move toward each other from both sides to the middle, or move away from each other from the middle to both sides. When the two push plates 22 move towards each other, the grease in the first oil collecting box 21 can be accelerated to be discharged.

Alternatively, the push plate 22 may have only one, and may reciprocate linearly in the first oil collecting box 21 toward the oil drain 25 or away from the oil drain 25.

Grease is attached to the push plate 22 during the movement of the push plate 22 to push the grease, and the push plate 22 needs to have a self-cleaning function in order to enable the push plate 22 to continuously and effectively function. Therefore, in the present embodiment, the pushing plate 22 includes the oil pushing plate 221 and the heat generating plate 222 embedded in the oil pushing plate 221, and when the heat generating plate 222 is powered on, the oil pushing plate 221 is in a hot state, and the hot oil pushing plate 221 helps to push the viscous grease on the one hand, and helps to melt and remove the grease on the surface of the first oil collecting box 21 after the grease runs out. Therefore, the grease in the first oil collecting box 21 can be removed quickly and effectively, and the daily cleaning time and energy of a user can be greatly saved.

The grease collecting device 2 further comprises an electromagnetic valve 27 for controlling the on-off of the grease leakage nozzle 25.

In order to facilitate automatic control of the grease collecting device 2, a liquid level detecting device is further arranged in the housing 1 and is positioned above the first grease collecting box 21. In the present embodiment, the liquid level detection means includes the infrared emission means 31 and the infrared reception means 32 provided in the housing 1 on the left and right sides, respectively, the infrared emission means 31 being obliquely oriented toward the inside of the first oil collection box 21, and the infrared reception means 32 being provided extending longitudinally. When the amount of grease in the first oil collecting box 21 is different, the infrared rays emitted by the infrared emitting device 31 are reflected by the grease liquid level and then reflected to different positions on the infrared receiving device 32, so that different amounts of grease can be distinguished and correspondingly displayed.

There are two display modes, one is to display numbers through a display screen on a panel 4 arranged on the front side of the shell 1, and if 1, 2 and 3 respectively represent the safe oil quantity, the middle oil quantity and the warning oil quantity. The other is that the cleaning and maintenance icon is distinguished by colors, such as green, red and yellow which are respectively used for representing the safe oil quantity, the middle oil quantity and the warning oil quantity. This technique detects the oil mass with reliable optical means, has avoided prior art to use transparent window user's own defect of observing, and this detection technique has avoided the error of contact liquid level test simultaneously, and it is more accurate to obtain information, can effectively avoid the grease to spill over through using this technique.

Of course, other prior art level sensing devices may be used.

In order to solve the problem of oil passage of the panel 4, a long hole 41 extending in the left-right direction is provided at a position close to the lower end of the panel 4, the grease collecting device 2 further includes an oil receiving mechanism 28, the front end of the oil receiving mechanism 28 extends from the long hole 41 of the panel 4 to the front side of the panel 4, and the rear end of the oil receiving mechanism 28 is communicated with the first oil collecting box 21. When the grease vapor forms droplets on the panel 4 and flows down, the grease vapor is caught by the oil catching mechanism 28 and finally flows into the first oil collecting box 21, so that the grease vapor is prevented from dripping on the surface of the cooking bench.

The plurality of elongated holes 41 can be arranged and staggered up and down, so that the condition that oil drops and water drops are not caught can be avoided. The term "staggered" means that adjacent elongated holes 41 are arranged vertically in the longitudinal direction and overlap each other in the transverse direction.

The liquid level detection device can be connected to a main controller of the range hood, and the main controller judges whether the grease collection device 2 needs to discharge oil according to signals of the liquid level detection device. The signal can also be detected by the liquid level detection device and processed and then directly transmitted to the driving mechanism 23 of the grease collecting device 2 so as to control the operation of the driving mechanism 23. In this embodiment, the control by the main controller is adopted.
