Description

Technical Field

[0001] The present disclosure relates to the technical field of smart home appliances, and in particular to a smart range hood. Background Art

[0002] In the prior art, the range hood still requires the user to manually select different gears according to the specific cooking conditions.

[0003] On the one hand, users need to constantly adjust the gear, which makes users feel the operating range and causes a bad cooking experience.

[0004] On the other hand, users cannot adjust the gear in time, and use a smaller gear when the oil smoke is heavy, resulting in failure to remove the oil smoke in time, or use a larger gear when the oil smoke is light, resulting in energy waste. Utility Model Content

[0005] In order to solve the above technical problems, the present invention provides a smart range hood.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The intelligent range hood provided by the present disclosure includes a fan, a control module, a first detection module and a second detection module;

[0008] The control module is electrically connected to the fan, the first detection module and the second detection module respectively;

[0009] The first detection module is arranged at the air inlet of the intelligent range hood;

[0010] The second detection module is arranged at the air outlet of the intelligent range hood;

[0011] The first detection module and the second detection module are both used to sense fog signals;

[0012] The control module is used to receive the fog signal and drive the fan to switch to a target working mode.

[0013] Optionally, the first detection module is used to sense a first fog signal, and the second detection module is used to sense a second fog signal;

[0014] The control module is used to drive the fan to switch to a low-speed working mode based on the received first fog signal, and to drive the fan to switch to a high-speed working mode based on the received first fog signal and the second fog signal.

[0015] Optionally, the first detection module includes a particle sensor, and the particle sensor is used to determine whether the first fog signal is the oil smoke signal or the water mist signal based on the size of particles in the fog.

[0016] Optionally, the second detection module includes an oil smoke sensor.

[0017] Optionally, the first detection module includes an oil fume sensor; and / or the second detection module includes an oil fume sensor.

[0018] Optionally, the control module is used to drive the fan to start based on the received first fog signal.

[0019] Optionally, the control module is further used to detect that the intelligent range hood is in a fault state and drive the fan to stop; wherein the fault state indicates that the control module receives the second fog signal but does not receive the first fog signal.

[0020] Optionally, the control module is used to detect a fog-free state and drive the fan to stop;

[0021] The non-fog state indicates that the control module does not receive the fog signal.

[0022] Based on the common sense in the art, the above-mentioned implementation modes can be arbitrarily combined to obtain the preferred embodiments of the present disclosure.

[0023] The positive and progressive effect of the present disclosure is that the fog signal is sensed by a first detection module arranged at the air inlet and a second detection module arranged at the air outlet, and the fan is driven to switch to different target working modes based on the fog signal, so as to realize intelligent control of the gear position of the fan. When cooking, oil smoke and water mist are usually generated at the same time. After the water mist is cooled by the fan, it cannot be detected at the air outlet. Therefore, when the first detection module detects fog, it is only necessary to intelligently switch the target working mode of the fan according to whether the second detection module can detect fog.

The appearance of the phrase in various places in the text does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this disclosure.

[0029] like Figure 1 As shown, the intelligent range hood 100 includes a fan 101, a control module, a first detection module 102 and a second detection module 103;

[0030] The control module is electrically connected to the fan 101, the first detection module 102 and the second detection module 103 respectively;

[0031] The first detection module 102 is disposed at the air inlet 104 of the smart range hood;

[0032] The second detection module 103 is disposed at the air outlet 105 of the smart range hood;

[0033] The first detection module 102 and the second detection module 103 are both used to sense fog signals;

[0034] The control module is used to drive the fan 101 to switch to a target working mode based on the received fog signal.

[0035] In one embodiment, the first detection module 102 is used to sense a first fog signal, and the second detection module 103 is used to sense a second fog signal;

[0036] The control module is used to drive the fan 101 to switch to a low-speed working mode based on the received first fog signal, and to drive the fan 101 to switch to a high-speed working mode based on the received first fog signal and the second fog signal.

[0037] It should be understood that the rotation speed of the fan 101 in the high-speed working mode is greater than that in the low-speed working mode.

[0038] For different cooking scenarios, although oil smoke and water mist are usually produced at the same time, the amount of oil smoke produced by cooking is different.

[0039] Furthermore, the water mist will condense into liquid after being cooled by the fan, and cannot be detected by the second detection module 103. Similarly, if a trace or a small amount of oil smoke is cooled by the fan, and the amount of oil smoke does not reach the detection threshold of the second detection module 103, the second detection module 103 cannot detect it. However, a large amount of oil smoke cannot be completely cooled after passing through the fan, and the oil smoke will still be detected by the second detection module 103.

[0040] Based on this, in this embodiment, if only the first detection module 102 can detect mist, it means that the user may be cooking that will produce less oil smoke, such as stir-frying, slow stewing, steaming and baking, etc., and the fan 101 only needs to run at a low speed to drain the water vapor. If the first detection module 102 and the second detection module 103 can detect mist at the same time, that is, the oil smoke and water mist are still detected by the air outlet 105 after being cooled by the fan 101, it means that the user may be cooking that will produce more oil smoke, such as stir-frying, deep-frying, smoking, etc., and the fan 101 needs to run at a high speed to exhaust the oil smoke.

[0041] Exemplarily, if the fan 101 is not running, the control module is used to drive the fan 101 to run at a low speed based on the received first fog signal. If the fan 101 is running at a high speed, the control module is used to drive the fan 101 to switch from high speed to low speed based on the received first fog signal.

[0042] Similarly, if the fan 101 is not running, the control module is used to drive the fan 101 to run at high speed based on the received first fog signal and the second fog signal. If the fan 101 is running at low speed, the control module is used to drive the fan 101 to switch from low speed to high speed based on the received first fog signal and the second fog signal.

[0043] In one embodiment, the first mist signal is an oil smoke signal or a water mist signal;

[0044] The control module is used to drive the fan 101 to a first speed based on the received water mist signal, and to drive the fan 101 to a second speed based on the received oil smoke signal;

[0045] The second rotation speed is greater than the first rotation speed.

[0046] The composition of the generated mist may be different for different cooking scenarios. For example, only water boiling and steaming usually only produce water mist and almost no oil smoke.

[0047] In this embodiment, for the low-speed working mode of the fan 101, the speed of the fan 101 can also be intelligently adjusted according to the composition of the mist. That is, if the first detection module 102 can only sense water mist, it means that the user may be cooking with almost no oil smoke, such as steaming or boiling, and the fan 101 can be operated at a lower speed in the low-speed working mode to drain the water vapor.

[0048] Specifically, the first detection module 102 includes a particle sensor, and the particle sensor is used to determine whether the first fog signal is an oil smoke signal or a water mist signal based on the size of particles in the fog.

[0049] Exemplarily, the particle sensor can determine whether the first fog signal is an oil smoke signal or a water mist signal according to the maximum value of the particle size of the fog. When the fog includes only oil smoke and includes both oil smoke and water mist, the maximum value of the particle size is smoke particles. When the fog includes only water mist, the maximum value of the particle size is water mist particles.

[0050] In one embodiment, the first detection module 102 includes an oil smoke sensor, or other sensors that can detect mist.

[0051] In another embodiment, the second detection module 103 includes an oil smoke sensor, or other sensors that can detect mist.

[0052] In one embodiment, the control module is used to drive the fan 101 to start based on the received first fog signal.

[0053] In this embodiment, the first detection module 102 arranged at the air inlet 104 usually detects smoke and water mist first, and drives the fan 101 to start at a set initial speed, and then further adjusts the rotation speed of the fan 101 according to whether the second detection module 103 detects fog, so as to achieve the effect of smooth start-up of the fan 101.

[0054] In another embodiment, the control module is used to detect a fog-free state and drive the fan 101 to stop;

[0055] The no-fog state indicates that the control module does not receive a fog signal.

[0056] In this embodiment, if the control module does not receive the mist signal, it means that the user has stopped cooking, and the fan 101 can be driven to stop in time, thereby achieving the effect of saving electricity.

[0057] In another embodiment, the control module is further used to detect that the intelligent range hood 100 is in a fault state and drive the fan 101 to stop; wherein the fault state indicates that the control module receives the second fog signal but does not receive the first fog signal.

[0058] If fog is generated during cooking, whether it is smoke or water mist, the air inlet 104 can definitely sense it. Therefore, if only the second detection module 103 senses the fog but the first detection module 102 does not, it means that the smart range hood may be faulty.

[0059] When the intelligent range hood is detected to be in a faulty state, the control module can prompt the user to carry out maintenance immediately through fault lights, alarm sounds, SMS notifications, etc.

[0060] Although the specific embodiments of the present disclosure are described above, those skilled in the art should understand that this is only an example, and the protection scope of the present disclosure is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present disclosure, but these changes and modifications all fall within the protection scope of the present disclosure.
