Description

Technical Field

[0001] The invention relates to the technical field of range hood design, and in particular to a range hood and a control method thereof. Background Art

[0002] The function of the range hood lighting is to provide lighting when cooking in dim light, which can avoid the waste of resources caused by turning on the kitchen light. The existing range hood lighting is fixed, and the light is fixed when in use. If the distance between the range hood and the stove changes due to the user's kitchen layout, when cooking in dim light, the range hood's built-in lighting may deviate from the stove, and there is no way to provide lighting conditions for the stove, resulting in poor user experience and waste of resources. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a range hood and a control method thereof, which can determine the position of the stove by detecting the real-time temperature through a temperature detection device, and control the direction of the lighting lamp toward the stove, without being affected by the user's kitchen layout, thereby improving user experience and avoiding waste of resources.

[0004] In order to solve the above technical problems, the technical solution proposed by the present invention is:

[0005] A range hood comprises a range hood body, wherein a lighting lamp is arranged on the range hood body, the lighting lamp is connected to the range hood body via an adjusting mechanism, the adjusting mechanism is used to adjust the position of the lighting lamp, a temperature detection device is arranged on the adjusting mechanism, a processing module electrically connected to the temperature detection device is arranged on the range hood body, and the processing module controls the adjusting mechanism to adjust the lighting direction of the lighting lamp toward a stovetop according to a measured temperature value of the temperature detection device.

[0006] According to the range hood of the present invention, by opening the left stove or the right stove on the stove, the processing module detects the temperature value in real time through the temperature detection device to determine the position of the stove, and controls the adjustment mechanism to adjust the lighting direction of the lighting lamp toward the stove, thereby avoiding the problem that the lighting direction of the lighting lamp deviates from the stove due to the influence of the user's kitchen layout. The range hood is suitable for various stoves and is not limited to the user's kitchen layout, which greatly improves the user experience and avoids waste of resources.

[0007] For the above technical solution, further improvements as described below can be made.

[0008] For the range hood according to the present invention, in a preferred embodiment, the adjusting mechanism includes a first adjustment component for adjusting the linear movement of the lighting lamp and a second adjustment component for adjusting the rotational movement of the lighting lamp. The first adjustment component and the second adjustment component are connected to each other. The lighting lamp is connected to the second adjustment component, and the temperature detection device is provided on the second adjustment component.

[0009] By adjusting the linear movement distance and the rotational angle of the lighting lamp through two sets of adjustment components respectively, the adjustment methods of the adjusting mechanism can be more, and the accuracy and efficiency of adjusting the position of the lighting lamp can be improved.

[0010] Specifically, in a preferred embodiment, the first adjustment component includes a push rod motor, and the second adjustment component is connected to the front end telescopic rod of the push rod motor.

[0011] Using a push rod motor to adjust the linear distance of the lighting lamp has a simple structure, convenient operation, and is easy to arrange and install.

[0012] Specifically, in a preferred embodiment, the second adjustment component includes a servo motor, and the temperature detection device is provided at the bottom of the servo motor.

[0013] Using a servo motor to adjust the rotational angle of the lamp makes the overall structure of the entire adjusting mechanism simple and compact, easy to install and arrange, and the operation process is simple and convenient.

[0014] Specifically, in a preferred embodiment, the lighting lamps are provided on both sides of the range hood main body.

[0015] By providing two sets of lighting lamps to illuminate the stoves on both sides respectively, the user experience of the range hood can be greatly improved.

[0016] The control method of the range hood according to the second aspect of the present invention is implemented by using the above-mentioned range hood, and includes the following steps: S01. Turn on the stove on the stove top to have a flame; S02. Control the adjusting mechanism to drive the lighting lamp to perform rotational movement and / or linear movement, and continuously judge whether the measured temperature value received by the temperature detection device is greater than or equal to the preset temperature value and whether the rotational angle of the lighting lamp is equal to the preset angle; until the measured temperature value is greater than or equal to the preset temperature value and the rotational angle of the lighting lamp is less than the preset angle, control the adjusting mechanism to stop working.

[0017] According to the control method of the range hood of the present invention, obviously, since the above-mentioned range hood is adopted, the processing module detects the temperature value in real time through the temperature detection device to judge the position of the stove top, and controls the adjusting mechanism to adjust the lighting direction of the lighting lamp towards the stove top, thereby being able to avoid the problem that the lighting direction of the lighting lamp deviates from the stove top due to the influence of the user's kitchen layout, being applicable to various cookers, not limited to the user's kitchen layout, and greatly improving the user experience.

[0018] For the above technical solution, the following further improvements can be made.

[0019] According to the control method of the range hood of the present invention, in a preferred embodiment, the adjusting mechanism includes a first adjusting component for adjusting the linear motion of the illuminating lamp and a second adjusting component for adjusting the rotational motion of the illuminating lamp. The first adjusting component and the second adjusting component are connected to each other. The illuminating lamp is connected to the second adjusting component. The temperature detection device is arranged on the second adjusting component. Step S02 includes the following sub-steps: S021. Control the second adjusting component to drive the illuminating lamp to perform a rotational motion, and continuously judge whether the measured temperature value received by the temperature detection device is greater than or equal to the preset temperature value, and judge whether the rotational angle of the illuminating lamp is equal to the preset angle; S022. If the measured temperature value is greater than or equal to the preset temperature value and the rotational angle of the illuminating lamp is less than the preset angle, control the second adjusting component to stop working; S023. If the rotational angle of the illuminating lamp is equal to the preset angle, control the second adjusting component to drive the illuminating lamp to reset to 0°; judge whether the linear distance that the first adjusting component drives the illuminating lamp to move forward is less than the first preset distance value; if not, control the first adjusting component to drive the illuminating lamp to move forward by a second preset distance value; if so, control the first adjusting component to drive the illuminating lamp to move backward by a second preset distance value; S024. Repeat steps S021 to S023 until the measured temperature value is greater than or equal to the preset temperature value and the rotational angle of the illuminating lamp is less than the preset angle, then control the second adjusting component to stop working.

[0020] Obviously, since two sets of adjusting components are used to perform linear motion and rotational motion respectively for adjustment, the above control method makes targeted adjustments for different states of the illuminating lamp, thus greatly improving the applicability of the entire control method, the accuracy of the control result, and the adjustment efficiency.

[0021] Specifically, in a preferred embodiment, the first preset distance is 15 cm and the second preset distance is 3 cm.

[0022] The above distance range of the linear motion can well ensure the stable and reliable adjustment process of the illumination angle of the illuminating lamp, and the adjustment result of the illumination angle is accurate and reliable.

[0023] Specifically, in a preferred embodiment, the preset angle is 90°.

[0024] Specifically, the upper limit value of the rotational angle of the illuminating lamp is set to 90°, that is, at this angle, the temperature detection device will definitely not detect the temperature of the cooking stove, so that the control and adjustment process can be more accurate and reliable, and the work efficiency can be improved.

[0025] Specifically, in a preferred embodiment, the preset temperature value is 90 - 110 °C.

[0026] Controlling the preset temperature value within the above range can effectively ensure the determination of the stove position based on the measured temperature value feedback by the temperature detection device, thereby ensuring the accurate and reliable adjustment of the illumination angle of the lighting lamp to a great extent.

[0027] Compared with the prior art, the advantages of the present invention are as follows: the position of the stove can be determined by detecting the real-time temperature through the temperature detection device, and the lighting direction of the lighting lamp can be controlled to face the stove, without being affected by the user's kitchen layout, thereby improving the user experience and avoiding waste of resources.

[0038] Embodiment 1

[0039] As Figures 1 to 5 shown, the range hood 10 of this embodiment includes a range hood main body 1. Among them, a lighting lamp 2 is arranged on the range hood main body 1. The lighting lamp 2 is connected to the range hood main body 1 through an adjusting mechanism 3. The adjusting mechanism 3 is used to adjust the position of the lighting lamp 2. A temperature detection device 4 is arranged on the adjusting mechanism 3. A processing module electrically connected to the temperature detection device 4 is arranged on the range hood main body 1. The processing module controls the adjusting mechanism 3 to adjust the lighting direction of the lighting lamp 2 to face the cooking stove 20 according to the actually measured temperature value of the temperature detection device 4.

[0040] For the range hood according to an embodiment of the present invention, by turning on the left or right stove on the cooking stove, the processing module uses the temperature detection device to detect the temperature value in real time to judge the position of the cooking stove, and controls the adjusting mechanism to adjust the lighting direction of the lighting lamp to face the cooking stove, so as to avoid the problem that the lighting direction of the lighting lamp deviates from the cooking stove due to the influence of the user's kitchen layout. It is applicable to various cookers, not limited to the user's kitchen layout, greatly improves the user experience, and avoids waste of resources.

[0041] As Figure 1 、 Figures 3 to 5 shown, specifically, in this embodiment, the adjusting mechanism 3 includes a first adjustment component 31 for adjusting the linear movement of the lighting lamp 2 and a second adjustment component 32 for adjusting the rotational movement of the lighting lamp 2. The first adjustment component 31 and the second adjustment component 32 are connected to each other. The lighting lamp 2 is connected to the second adjustment component 32. The temperature detection device 4 is arranged on the second adjustment component 32. By adjusting the linear movement distance and rotational angle of the lighting lamp through the two groups of adjustment components respectively, the adjustment method of the adjusting mechanism can be more, and the accuracy and efficiency of adjusting the position of the lighting lamp can be improved. Specifically, in this embodiment, the first adjustment component 31 includes a push rod motor, and the second adjustment component 32 is connected to the front end telescopic rod 311 of the push rod motor. Using a push rod motor to adjust the linear distance of the lighting lamp has a simple structure, convenient operation, and is easy to arrange and install. Specifically, in this embodiment, the second adjustment component 32 includes a servo motor, and the temperature detection device 4 is arranged at the bottom of the servo motor. Using a servo motor to adjust the rotational angle of the lamp makes the overall structure of the entire adjusting mechanism simple and compact, easy to install and arrange, and the operation process is simple and convenient. Moreover, a temperature detection device such as an infrared temperature sensor is arranged below the servo motor, which can more accurately obtain the temperature data of the opened stove on the cooking stove in real time, so as to greatly improve the accuracy and efficiency of adjusting the lighting direction of the lighting lamp.

[0042] AsFigure 1 , Figure 2 and Figure 5 As shown in Figure 1 , Figure 2 and Figure 5 , specifically, in this embodiment, the lighting lamps 2 are arranged on both sides of the main body 1 of the range hood. By providing two groups of lighting lamps for illuminating the stoves on both sides respectively and controlling and adjusting the left and right stoves respectively, the user experience of the range hood can be greatly improved. Specifically, in this embodiment, a groove 11 for arranging the lighting lamps 2 and the adjusting mechanism 3 is provided on the main body of the range hood, and the push rod motor is arranged at the upper end 111 of the groove.

[0043] Specifically, in this embodiment, the temperature detection device 4 is an infrared temperature sensor, which passively absorbs the infrared radiation energy of the flame of the stove that has been turned on on the stove top, so as to obtain the temperature value.

[0044] Embodiment 2

[0045] As Figure 6 shown in Figure 6 , the control method of the range hood according to the embodiment of the present invention is implemented by using the range hood of the above Embodiment 1, and includes the following steps: S01, turn on the stove on the stove top 20 to have a flame; S02, control the adjusting mechanism to drive the lighting lamp to perform rotational motion and / or linear motion, and continuously judge whether the measured temperature value received by the temperature detection device is greater than or equal to the preset temperature value and whether the rotation angle of the lighting lamp is equal to the preset angle; until the measured temperature value is greater than or equal to the preset temperature value and the rotation angle of the lighting lamp is less than the preset angle, control the adjusting mechanism to stop working.

[0046] According to the control method of the range hood according to the embodiment of the present invention, obviously, since the above range hood is adopted, the processing module detects the temperature value in real time through the temperature detection device to judge the position of the stove top, and controls the adjusting mechanism to adjust the lighting direction of the lighting lamp to face the stove top, so as to avoid the problem that the lighting direction of the lighting lamp deviates from the stove top due to the influence of the user's kitchen layout. It is applicable to various cookers and is not limited to the user's kitchen layout, greatly improving the user experience. Among them, the preset angle is set with reference to the angle at which the temperature detection device cannot detect the flame temperature on the stove top, that is, at the position adjusted to the preset angle, the lighting direction of the super lighting lamp is not facing the direction of the stove top.

[0047] As Figure 2As shown in the figure, specifically, in this embodiment, the lighting lamps 2 are divided into two groups and are respectively arranged at positions on both sides of the main body 1 of the range hood corresponding to two groups of stoves 21 on the cooking range 20. The two groups of lighting lamps 2 are respectively controlled and adjusted according to the user's needs. When adjusting the lighting lamps 2, it is necessary to turn on the stove 21 corresponding to this group of lighting lamps 2 to make it have a flame, and then enter the lighting lamp control interface. The push rod motor starts to work after a delay of 2-4S, especially preferably 3S. The working mode is that the push rod motor does not move first, and the steering gear is controlled to make a rotational movement. During the rotation process, the infrared temperature sensor under the steering gear detects the received temperature value. When the processing unit determines that the rotation angle is less than the preset angle and the temperature value is greater than or equal to the preset temperature value, the steering gear stops rotating, and the current lighting angle of the lighting lamp is the final lighting angle.

[0048] Specifically, in this embodiment, the preset angle is preferably 90°. Specifically, the upper limit value of the rotation angle of the lighting lamp is set to 90°, that is, at this angle, the temperature detection device must not be able to detect the temperature of the cooking appliance, so that the control and adjustment process can be more accurate and reliable, and the work efficiency can be improved. Specifically, in this embodiment, the preset temperature value is 90-110°C, especially preferably 100°C. Controlling the preset temperature value within the above range can effectively ensure that the position of the cooking range is judged through the measured temperature value feedback by the temperature detection device, thereby ensuring that the adjustment of the lighting angle of the lighting lamp is accurate and reliable to a great extent.

[0049] As Figure 3 , Figure 4 and Figure 6 As shown in the figure, specifically, step S02 includes the following sub-steps: S021, control the steering gear to drive the lighting lamp to make a rotational movement, and continuously judge whether the measured temperature value received by the infrared temperature sensor is greater than or equal to the preset temperature value of 100°C, and judge whether the rotation angle of the lighting lamp is equal to the preset angle of 90° according to the rotation angle of the steering gear; S022, if the measured temperature value is greater than or equal to the preset temperature value of 100°C and the rotation angle of the lighting lamp is less than the preset angle of 90°, then control the steering gear to stop working; S023, if the rotation angle of the lighting lamp is equal to the preset angle of 90°, control the steering gear to drive the lighting lamp to reset to 0°, that is, the steering gear angle rotates to 0°; judge the linear distance that the push rod motor drives the lighting fixture to move forward, that is, the positive direction movement distance relative to the origin, and whether it is less than the first preset distance value; if not, then control the push rod motor to drive the lighting lamp to continue to extend forward by the second preset distance value; if so, then control the push rod motor to drive the lighting lamp to retract backward by the second preset distance value along the negative direction; S024, repeat the above steps S021-S023 until the measured temperature value is greater than or equal to the preset temperature value of 100°C and the rotation angle of the lighting lamp is less than the preset angle of 90°, then control the steering gear to stop working. As Figure 3As shown in the figure, where α is the angle by which the servo drives the lighting lamp to rotate, and L is the distance by which the front telescopic rod of the push rod motor drives the servo to translate back and forth. Obviously, since two sets of adjustment components are used to perform linear motion and rotational motion respectively for adjustment, the above control method makes targeted adjustments for different states of the lighting lamp, thereby greatly improving the applicability of the entire control method, the accuracy of the control result, and the adjustment efficiency.

[0050] Specifically, in this embodiment, the first preset distance is 15 cm, and the second preset distance is 3 cm. The above distance range of linear motion can well ensure the stable and reliable adjustment process of the lighting angle of the lighting lamp, and the adjustment result of the lighting angle is accurate and reliable.

[0051] According to the above embodiment, it can be seen that the range hood and its control method involved in the present invention can detect the real-time temperature through the temperature detection device to determine the position of the cooking range, and control the lighting direction of the lighting lamp to face the cooking range, without being affected by the user's kitchen layout, thereby improving the user experience and avoiding waste of resources.
