Example

[0026] First embodiment

[0027] Please refer to figure 2 , Is a structural block diagram of the oil level detection device 200 provided by the first embodiment of the present invention. The oil level detection device 200 includes a controller 201, a distance sensor 202, a memory 203, a communication module 204, and an alarm 205. The distance sensor 202, the memory 203, the communication module 204, and the alarm 205 are all electrically connected to the controller 201, the housing includes a cavity, the controller 201, the memory 203, the communication module 204 and the alarm 205 is arranged in the cavity.

[0028] The distance sensor 202 is used to detect the distance to the oil surface of the oil cup 100. Specifically, the distance measurement can be performed at a preset time. For example, the controller 201 controls the distance sensor 202 to perform distance measurement every 30 minutes after the range hood 10 starts. The distance sensor 202 also sends the measured dista...

Example

[0039] Second embodiment

[0040] Please refer to Figure 4 And combine figure 1 , Figure 4 It is a partial structural diagram of the range hood 10 provided by the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the distance sensor 202 of this embodiment can be arranged on the side wall of the range hood 10, and the distance sensor 202 can be an infrared rangefinder or a laser rangefinder.

[0041] The distance sensor 202 and the reflecting mirror 206 are respectively arranged on the first side wall 11 and the second side wall 12. The distance sensor 202 can measure the distance between the probe of the distance sensor 202 and the bottom of the oil cup 100 when the range hood 10 is used for the first time and the oil cup 100 is empty, as the initial distance. When the range hood 10 is in use, each time the distance sensor 202 performs a measurement, the detected distance between the probe of the distance sensor 2...

Example

[0044] The third embodiment

[0045] Please refer to Figure 5 , Is a flowchart of the oil level detection method provided by the third embodiment of the present invention. The oil level detection method includes:

[0046] Step S101, measuring the distance between the distance sensor 202 and the bottom of the oil cup 100 when the oil cup 100 is in an empty cup state.

[0047] When the distance sensor 202 is used for the first time in the range hood 10 and the oil cup 100 is empty (no oil in the oil cup), the distance between the probe of the distance sensor 202 and the bottom of the oil cup 100 is measured as the initial distance, and This initial distance is stored in the memory 203.

[0048] Step S102, at a preset time, measure the distance between the distance sensor 202 and the oil surface in the oil cup 100. When the range hood 10 is in use, each time the distance sensor 202 performs a measurement (for example, every 30 minutes after power-on), the detected distance between th...

Abstract

The invention provides an oil level detection method, an oil level detection device and a range hood, and relates to the technical field of the range hoods. The oil level detection device adopts a range sensor to carry out real-time detection on the oil level height, and by combing with different mounting modes of the range sensor, the range hood is more attractive, and is simple in structure and convenient to mount. Data is transmitted to a mobile phone through a communication module, so that a user can be informed of an oil level situation in an oil cup more visually, and oil level information can be pushed remotely and reminds the user of cleaning the oil cup.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an oil level detection method and device and a range hood. Background technique [0002] At present, many oil cups on the range hood are opaque. During the use of the range hood, the oil level in the oil cup will gradually rise until the oil cup reaches its maximum value. The user has to clean the oil cup regularly. Otherwise, phenomena such as oil dripping may occur during cooking, which directly affects the cooking experience of the user. In the existing patents, it is mentioned that the oil level is detected by a temperature sensor, but the detection device must be in direct contact with the oil, and the control scheme is more complicated; in addition, a float switch is also used to detect the oil level, but this kind of scheme The structural design is difficult, and the float switch is prone to be stuck, which may fail after a long time. In addition, this method can only...
