Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen appliance technology, and in particular to a concealed range hood control method and a concealed range hood. Background Technology
[0002] As one of the core appliances in the kitchen, the range hood's function is to promptly remove cooking fumes and keep the kitchen air fresh. With the continuous improvement of living standards, in addition to their performance, the smart features and convenience of various appliances are increasingly valued by users.
[0003] In existing technology, range hoods primarily rely on user-operated buttons to control various functions. These buttons are typically located on the control panel and include a start button, fan speed adjustment button, and lighting button. Users must first press the start button to turn on the range hood. Once running, they then use other buttons to adjust fan speed, turn the lighting on or off, etc., depending on the cooking situation. This control structure is relatively mature in technology and has controllable costs, thus it is widely used in various range hood products.
[0004] However, when using a range hood, users not only need to perform multiple operation steps in sequence, starting it first and then adjusting its status, which is quite cumbersome, but also need to wait for a period of time for the range hood to reach the corresponding state. During this period, the range hood may not be able to effectively remove the fumes in a timely manner, resulting in poor intelligence of the range hood itself and a poor user experience. Summary of the Invention
[0005] The purpose of this invention is to provide a concealed range hood control method and a concealed range hood, which solves the problems of cumbersome control process, time-consuming operation, poor smoke extraction effect, poor intelligence, and poor user experience of existing range hoods.
[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] Obtain the user's location information and control the range hood to enter a wake-up state based on the location information;
[0009] Acquire control signals and control the range hood to switch between various suction states in a hidden state based on the control signals;
[0010] Obtain a shutdown signal and control the cigarette to shut off according to the shutdown signal.
[0011] Optionally, acquiring the control signal and controlling the range hood to switch between multiple suction states in the hidden state according to the control signal specifically includes:
[0012] Obtain a first signal, and control the side suction port of the range hood to open to a first amplitude according to the first signal, so that the range hood switches from the hidden state to the first suction state;
[0013] A second signal is acquired, and the side suction port of the range hood is controlled to open to a second amplitude according to the second signal, so that the range hood enters a second suction state, wherein the second amplitude is greater than the first amplitude.
[0014] Optionally, when the first signal is acquired, the fan of the range hood enters a first power mode, and when the second signal is acquired, the fan of the range hood enters a second power mode, and the power of the second power mode is greater than the power of the first power mode.
[0015] Optionally, acquiring the control signal and controlling the range hood to switch between multiple suction states in the hidden state according to the control signal specifically includes:
[0016] A third signal is obtained, and the smoke machine is controlled to enter a hidden state and the side suction port is closed according to the third signal so that suction can be performed through the top suction port.
[0017] Optionally, the fan of the smoke hood is controlled to enter a third power mode according to the third signal, the power of the third power mode being less than the power of the first power mode.
[0018] Optionally, the step of acquiring a power-off signal and controlling the cigarette to turn off based on the power-off signal specifically includes:
[0019] Obtain the first shutdown signal, generate a delay signal based on the first shutdown signal, wait for a first time, and then turn off the range hood and put the range hood into a hidden state.
[0020] Optionally, the step of acquiring a power-off signal and controlling the cigarette to turn off based on the power-off signal specifically includes:
[0021] Obtain a second shutdown signal, and control the smoke machine to shut down and enter a hidden state based on the second shutdown signal.
[0022] Optionally, in the wake-up state, if the user's location information is not detected for a second period of time, the range hood exits the wake-up state.
[0023] Optionally, acquiring the control signal and controlling the range hood to switch between multiple suction states in the hidden state according to the control signal specifically includes:
[0024] The system acquires a fourth signal, and adjusts the lighting status of the range hood based on the fourth signal, while generating a prompt signal to remind the user during the adjustment process.
[0025] Secondly, this application provides a concealed range hood, which is controlled by the concealed range hood operation method as described in any one of the first aspects, the concealed range hood comprising:
[0026] The chassis has a top suction port;
[0027] Fan; installed in the aforementioned chassis;
[0028] The smoke collection shell is slidably connected to the chassis and has a side suction port;
[0029] A drive mechanism is connected to the smoke-collecting shell to drive the smoke-collecting shell to extend into the housing to hide or extend out of the housing to open and adjust the size of the side suction port, thereby enabling the concealed smoke machine to switch between a concealed state and multiple suction states.
[0030] The beneficial effects of this invention are:
[0031] Firstly, using the aforementioned method, when a user enters the kitchen and approaches the range hood, the control module within the range hood can acquire the user's location information and, based on this information, control the range hood to enter a wake-up state. In this wake-up state, all components of the range hood are in standby mode. When the user generates a control signal, all mechanisms of the range hood can immediately activate, and the user can flexibly switch between a hidden state and various suction states as needed. After switching, the range hood can quickly reach the corresponding state. Therefore, by controlling the hidden range hood using this hidden control method, the range hood can be woken up in advance based on the user's location, allowing it to quickly reach the desired state when the user operates it, thereby effectively removing the corresponding gas. This simplifies the control process of the range hood, shortens the time it takes for the range hood to reach the desired state, and improves both the intelligence level of the range hood itself and the user experience.
[0032] Secondly, when this concealed range hood is in use, it automatically enters a wake-up state upon detecting the user's location information. After the user inputs a control signal, the drive mechanism can control the smoke collection shell to open the side suction port, and the fan will run accordingly, allowing the range hood to quickly switch from the concealed state to the corresponding suction state. This effectively reduces the waiting time for the user, promptly extracts oil fumes and other gases in the kitchen, improves the intelligence of the range hood, and effectively enhances the user experience.

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0044] like Figures 1 to 5 As shown, the present invention provides a concealed range hood control method and a concealed range hood.
[0045] Reference Figure 1 The operation method of this concealed range hood includes:
[0046] Step S1: Obtain the user's location information and control the range hood to enter the wake-up state based on the location information.
[0047] Concealed range hoods are installed inside kitchen wall cabinets. They use infrared sensors and other detection elements to create a sensing area in the kitchen. When a user enters the sensing area, the system can obtain the user's location information and control the range hood to enter a wake-up state. The wake-up state means that some lights on the surface of the range hood are lit, such as the logo light, the fan enters standby mode, and an audible signal, such as a "beep" or continuous music, can be emitted to remind the user that the range hood has been automatically woken up.
[0048] Step S2: Obtain the control signal and control the range hood to switch between various suction states in the hidden state according to the control signal.
[0049] Control signals are generated by the user's touch control panel, such as operation signals and switching signals. Upon receiving a control signal, the smoke-collecting shell hidden inside the range hood can extend to open the side suction port. At this time, the range hood enters the top and side dual suction mode. In this suction mode, the suction power can be further adjusted according to the switching signal, thereby switching between different suction states, such as strong suction and maximum suction. After receiving a control signal, the range hood can also remain hidden without extending the smoke-collecting shell, in which case the range hood enters the top suction mode.
[0050] Step S3: Obtain the shutdown signal and control the cigarette to turn off according to the shutdown signal.
[0051] The shutdown signal is generated by the user's touch control panel. When the user needs to stop the operation of the range hood, they can input the shutdown signal to turn off the range hood. At this time, the range hood's fan and all lights will turn off.
[0052] Through steps S1 to S3, when a user enters the kitchen and approaches the range hood, the control module within the range hood can acquire the user's location information and control the range hood to enter a wake-up state based on this information. In the wake-up state, all components of the range hood are in standby mode. When the user generates a control signal, all mechanisms of the range hood can immediately start, and the user can flexibly switch between a hidden state and various suction states as needed. After switching, the range hood can quickly reach the corresponding state. Therefore, by controlling the hidden range hood using this hidden control method, the range hood can be woken up in advance based on the user's location, allowing it to quickly reach the desired state when the user operates it, thereby effectively removing the corresponding gas. This simplifies the control process of the range hood, shortens the time it takes for the range hood to reach the corresponding state, and improves both the intelligence level of the range hood and the user experience.
[0053] Optionally, step S2 above specifically includes:
[0054] Step S21: Obtain the first signal, and control the side suction port of the range hood to open to the first amplitude according to the first signal, so that the range hood switches from the hidden state to the first suction state.
[0055] The first signal is generated by the user operating the control panel, such as by touching a specific location or tapping any location on the control panel once. Based on the first signal, the drive mechanism inside the range hood is activated to lower the smoke-collecting shell hidden inside the range hood to a first position. At this time, the side suction port opens to a first amplitude, thus switching the range hood from a hidden state to the first suction state. In this embodiment, when the first signal is received, the smoke-collecting shell lowers 200mm to the first position.
[0056] Step S22: Obtain the second signal, and control the side suction port of the range hood to open to the second amplitude according to the second signal, so that the range hood enters the second suction state, the second amplitude of which is greater than the first amplitude.
[0057] Similarly, the second signal can be generated by the user touching the corresponding position or tapping the control panel twice, with the interval between the two taps ≤0.5s. Based on the second signal, the drive structure continues to drive the smoke-collecting shell down to the second position. The second position is lower than the first position and closer to the cooktop. At this point, the side suction port can open to the second amplitude and enter the second suction state. In this state, the communication area of the side suction port reaches its maximum, and the side suction efficiency is optimal, suitable for the user's stir-fry mode. In this embodiment, when the second signal is received, the smoke-collecting shell descends another 150mm to the second position.
[0058] Through steps S21 and S22, users can easily switch the range hood between a hidden state, a first suction state, and a second suction state by operating the control panel, thus adjusting the different side suction efficiencies of the range hood to flexibly adapt to different cooking needs. In the first and second suction states, different lights can flash on the range hood to remind the user; for example, the speed of the running lights is faster in the second suction state than in the first suction state.
[0059] Optionally, step S2 above specifically includes: when the first signal is acquired, the fan of the range hood enters the first power mode; when the second signal is acquired, the fan of the range hood enters the second power mode, and the power of the second power mode is greater than the power of the first power mode.
[0060] When the first signal is received, the side suction vent opens to its first amplitude. At this point, the user requires efficient suction, and the fan is controlled to enter the first power mode (high-speed mode) according to the first signal. When the second signal is received, the side suction vent opens to its second amplitude. At this point, the user requires maximum suction, and the fan is controlled to enter the second power mode (maximum airflow mode) according to the second signal. This eliminates the need for the user to separately adjust the fan power. The user only needs to generate the corresponding signal through the control panel to simultaneously adjust the opening size of the side suction vent and the fan power, further simplifying operation and making it easier for the user to control the range hood.
[0061] Optionally, step S2 above may further include:
[0062] When the first or second signal is received, the position and lifting speed of the smoke collection shell inside the side suction port are detected. When the position of the smoke collection shell exceeds the preset position or the lifting speed is lower than the preset speed (the preset speed can be 0.5cm / s), the drive structure is controlled to stop running, and a warning signal is generated, such as a continuous "beep" sound or music, to remind the user that the lifting of the smoke collection shell is abnormal and to carry out maintenance in time.
[0063] Optionally, step S2 above further includes:
[0064] Step S23: Obtain the third signal, and control the range hood to enter the hidden state and close the side suction port according to the third signal, so as to perform suction through the top suction port.
[0065] The third signal can be generated by the user touching the corresponding position or tapping the control panel three times. It can also further simplify the control logic. When the range hood is in the second suction state, the user can generate the third signal by tapping the control panel twice. At this time, the range hood enters the hidden state, that is, the smoke collection shell extends into the range hood to close the side suction port, and only suction is performed through the top suction port to suit the user's steaming and cooking.
[0066] Optionally, the fan of the smoke hood is controlled to enter a third power mode according to the third signal, and the power of the third power mode is less than that of the first power mode.
[0067] When the third signal is received, the range hood only draws air through the top suction port, and the fan simultaneously enters the third power mode, which is a low airflow mode. This reduces noise while still efficiently drawing air through the top suction port.
[0068] Optionally, step S2 above further includes:
[0069] The system acquires a fourth signal, and uses this signal to turn the range hood on and off and adjust its lighting status. During the adjustment process, it can generate a prompt signal to remind the user.
[0070] When the range hood enters the wake-up state, regardless of whether the range hood is in a hidden state or in any suction state, the user can generate a fourth signal by touching a designated part or tapping the control panel three or more times. After obtaining the fourth signal, the range hood's lighting module switches between on and off, and the brightness of the lighting can also be adjusted. At the same time, it can generate sound, music or flashing lights as prompts to remind the user.
[0071] Optionally, step S3 above specifically includes:
[0072] Step S31: Obtain the first power-off signal, generate a delay signal based on the first power-off signal, and after waiting for a first time, turn off the range hood and put the range hood into a hidden state.
[0073] The first shutdown signal is input by the user while the range hood is running. This can be generated by touching a designated area or pressing and holding the control panel for 3 seconds or longer. Upon receiving the first shutdown signal, a corresponding delay signal is generated. The fan continues to run for the initial delay before stopping, and the smoke collection casing resets and retracts into the range hood. The initial delay can be 30 seconds or 60 seconds, the length of which can be set by the user. By setting a delayed shutdown, the range hood continues to run for a period after the user inputs the first shutdown signal, thus fully extracting the corresponding gases from the kitchen and further improving the suction effect.
[0074] Step S32: Obtain the second shutdown signal, and control the smoke machine to turn off and put the smoke machine into a hidden state according to the second shutdown signal.
[0075] The second shutdown signal is a user-input signal that forces the range hood to shut down. This signal can be generated by pressing and holding the control panel for 5 seconds or longer. When the second shutdown signal is received, the fan immediately shuts down and the smoke collection plate resets. The first joint signal and the second shutdown signal can be selectively input by the user to meet different suction needs.
[0076] Optionally, in the wake-up state, if the user's location information is not detected for a second period of time, the range hood exits the wake-up state.
[0077] When a user enters the kitchen and approaches the range hood, the range hood automatically enters a wake-up state. When the user no longer needs the range hood and leaves the kitchen, the range hood will no longer detect the user's location. After continuous detection for a certain period of time, the range hood will exit the wake-up state and enter a sleep state to reduce energy consumption. The second period of time can be 30 seconds, 20 seconds, etc., and this application does not limit it.
[0078] Reference Figure 2 In summary, this concealed range hood control method first acquires the user's location information and then controls the range hood to enter a wake-up state based on this information. At this time, the range hood's logo light illuminates, and the fan enters standby mode. In the wake-up state, if the user's location information is not detected for a duration exceeding a second time, the wake-up state is exited. In the wake-up state, the user can input a first, second, or third signal, and the range hood can quickly enter the first, second, or third suction state. The opening range of the side suction vents differs in each suction state, and the fan's operating power also varies. In any suction state, the user can input a fourth signal to switch the lighting state. When a shutdown is required, the user can selectively input a first and second shutdown signal. The first shutdown signal generates a delay signal; if the delay exceeds the first time, the range hood stops and shuts down. When the user inputs the second shutdown signal, the range hood immediately stops and shuts down.
[0079] Reference Figures 3 to 5 The concealed range hood is controlled using the aforementioned concealed range hood operation method. The concealed range hood includes a housing 1, a fan 2, a smoke collection shell 3, and a drive mechanism 4. The housing 1 has a top suction port; the fan 2 is disposed in the housing 1; the smoke collection shell 3 is slidably connected to the housing 1 and has a side suction port 31; the drive mechanism 4 is connected to the smoke collection shell 3 to drive the smoke collection shell 3 to extend into the housing 1 to hide or extend out of the housing 1 to open and adjust the size of the side suction port 31, thereby enabling the concealed range hood to switch between a hidden state and various suction states.
[0080] When in use, this concealed range hood automatically enters a wake-up state upon detecting the user's location information. After the user inputs a control signal, the drive mechanism 4 controls the smoke collection shell 3 to open the side suction port 31, and the fan 2 operates accordingly, allowing the range hood to quickly switch from the concealed state to the corresponding suction state. This effectively reduces the waiting time for the user, promptly extracts fumes and other gases in the kitchen, improves the intelligence of the range hood, and effectively enhances the user experience.
