Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] As people's living standards improve, range hoods are increasingly being used in homes to meet the demand for fume extraction and kitchen environment purification.

[0003] Conventional range hoods use control buttons on the control module to start / stop the range hood and adjust the airflow. To improve the intelligent control of range hoods, existing technology provides a method for linking the range hood and the cooktop. This method uses a gesture recognition module on the cooktop to recognize the user's gestures, thereby controlling the start / stop of the range hood.

[0004] However, the existing technology that uses gesture recognition to control the start and stop of the range hood and adjust the air volume has a high error rate. During cleaning or other operations, the range hood may be accidentally started. At the same time, some users, especially elderly users, find it difficult to operate the range hood by gesture recognition, which is not conducive to improving the user experience of the range hood. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a range hood that can effectively solve the problems of difficult operation and low control accuracy of the start and stop control of existing range hoods, improve the intelligence level of the range hood, and improve the user experience of the range hood.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] A range hood includes a control module and a smoke collection hood with a control mounting cavity. The smoke collection hood has a smoke collection bottom plate forming the bottom of the control mounting cavity and a front cover plate forming the front side wall of the control mounting cavity. The control module is installed in the control mounting cavity. The smoke collection bottom plate has a sound pickup hole, and the front cover plate has an identification hole.

[0008] The range hood also includes a microphone, an audio recognition module, and a human body recognition module. The microphone is positioned directly opposite the microphone hole. The audio recognition module is communicatively connected to both the control module and the microphone to identify ambient sound signals picked up by the microphone and transmit them to the control module. The human body recognition module is installed in the control mounting cavity and positioned directly opposite the recognition hole. The human body recognition module is communicatively connected to the control module and is used to identify whether a human body is present in front of the range hood.

[0009] Compared with the prior art, the range hood described in this utility model has the following advantages: The audio recognition module combined with the human body recognition module can help determine whether a user is present in front of the range hood and whether the user has turned on the stove to prepare for cooking. Compared to solely detecting ambient sound to determine stove use, this effectively avoids misjudgments caused by ambient sound recognition bias, improving the start-up control accuracy of the range hood. Simultaneously, by opening a pickup hole on the smoke collection base plate, the microphone can face downwards towards the stove, minimizing interference from other directions and improving the reliability of the microphone's recognition of ignition and / or combustion sounds. By installing the human body recognition module and audio recognition module in the control mounting cavity, and by opening recognition holes on the front panel, the human body recognition module can identify the human body through the recognition holes, while simultaneously shortening the distance between the human body recognition module, audio recognition module, and control module. This facilitates communication between the human body recognition module, audio recognition module, and control module, simplifying the installation of the human body recognition module and audio recognition module.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] This embodiment provides a range hood that can extract and exhaust oil fumes to purify the kitchen environment, while also enhancing the linkage function between the range hood and the stove, thereby improving the intelligent control of the range hood.

[0043] Specifically, such as Figures 1 to 7 As shown, the range hood includes a smoke collection hood 1, a fan module 6, and a control module. The smoke collection hood 1 has a smoke inlet 118; the fan module 6 includes a fan 61, which operates to create negative pressure at the smoke inlet 118, causing smoke to enter the smoke collection hood 1 from the smoke inlet 118 and be discharged through the fan 61; the control module is installed in the smoke collection hood 1 and is communicatively connected to the fan 61, enabling the control module to control the operation of the fan 61.

[0044] The top of the smoke hood 1 has a control mounting cavity, in which the control module is installed. The smoke hood 1 has a smoke collecting base plate 111 forming the bottom of the control mounting cavity, and a sound pickup hole 1111 is vertically provided through the smoke collecting base plate 111. The smoke hood 1 has a front hood plate 112 forming the front wall of the control mounting cavity, and an identification hole 1121 is provided on the front hood plate 112.

[0045] The range hood also includes an identification component 2 and a microphone 3. The microphone 3 is installed on the smoke collection base plate 111 and located in the middle of the smoke collection hood 1 along the left-right direction. The microphone 3 is installed in the sound pickup hole 1111. The identification component 2 includes an audio identification component 2 and a human body identification component 2. The microphone 3 is positioned directly opposite the sound pickup hole 1111. The audio identification module 21 is communicatively connected to both the control module and the microphone 3 to identify the ambient sound signals picked up by the microphone 3 and transmit them to the control module. The human body identification module 22 is installed in the control mounting cavity and positioned directly opposite the identification hole 1121. The human body identification module 22 is communicatively connected to the control module and is used to identify whether there is a human body in front of the range hood.

[0046] The range hood provided in this embodiment uses a microphone 3 and an audio recognition module 21 to identify and analyze ambient sounds, thereby determining whether there is a pulse ignition sound and / or a gas combustion sound, and thus whether the cooktop 100 is in use. Simultaneously, by combining the human body recognition module 22 to detect the presence of a user in front of the range hood, it can more accurately determine whether the user has turned on the cooktop 100 to prepare for cooking. When it is determined that the cooktop 100 is turned on and a user is present in front of the range hood, the control module can control the fan 61 to start running without additional operation, achieving intelligent control of the fan 61 and reducing the difficulty of operating the range hood. Compared to solely detecting ambient sounds to determine whether the cooktop 100 is in use, this effectively avoids misjudgments caused by ambient sound recognition errors, improving the accuracy of the range hood's start-up control. Furthermore, by using the microphone 3 and the audio recognition module 21 to determine whether the cooktop 100 is turned on, there is no need to set up an additional structure on the cooktop 100 to achieve cooktop-range hood linkage, ensuring the reliability of the linkage while simplifying the setup of the cooktop-range hood linkage structure.

[0047] Furthermore, by opening a pickup hole in the smoke collection base plate, the microphone can face downwards towards the stove, thus minimizing interference from sounds from other directions and improving the reliability of the microphone in recognizing ignition and / or combustion sounds. By installing the human body recognition module and audio recognition module in the control mounting cavity, and by opening recognition holes in the front panel of the cover, the human body recognition module can recognize the human body through the recognition holes, while shortening the distance between the human body recognition module, audio recognition module and control module, thereby facilitating communication between the human body recognition module, audio recognition module and control module, and simplifying the installation of the human body recognition module and audio recognition module.

[0048] In one embodiment, the range hood also includes a lighting lamp 7, which is communicatively connected to the control module. While the control module controls the start and stop of the fan 61 based on the identification component 2 and the microphone 3, it also controls the operation of the lighting lamp 7, thereby further improving the intelligence level of the range hood and enhancing the user experience.

[0049] like Figure 2 and Figure 3As shown, in one embodiment, the smoke hood 1 includes a main hood body 11 and an upper cover body 12. The main hood body 11 has a smoke-collecting base plate 111 and a front hood plate 112, and has a top groove with an upper opening. The upper cover body 12 includes a cover plate portion 121 and a side plate portion 122 surrounding the periphery of the cover plate portion 121. The side plate portion 122 is inserted into the top groove. The cover plate portion 121 covers the upper opening of the top groove and, together with the main hood body 11, forms a smoke-collecting cavity and a control mounting cavity. The front side plate portion 122 is provided with a clearance opening 1221 corresponding to the human body recognition module 22 and / or the audio recognition module 21. The main hood body 11 is provided with a smoke inlet 118, which communicates with the smoke-collecting cavity.

[0050] By setting the upper cover 12 and the main cover 11 together to realize the smoke collection chamber and the control installation chamber, it is convenient to disassemble and assemble the control module, the identification component 2 and the microphone 3, thereby improving the convenience of disassembly, assembly and maintenance of the range hood; by setting the upper cover 12 with the cover plate part 121 and the side plate part 122, the side plate part 122 is used to improve the convenience of matching with the main cover 11, thereby improving the assembly efficiency and assembly accuracy of both; by setting the avoidance opening 1221 on the front side plate part 122, it is possible to avoid the side plate part 122 from affecting the disassembly and assembly of the human body recognition module 22 and / or the audio recognition module 21.

[0051] To improve the ease of assembly and disassembly of the upper cover 12, in one embodiment, a raised rib 116 is provided on the groove wall of the top groove, and a buckle 123 is provided on the side plate 122. The buckle 123 engages with the raised rib 116, thereby facilitating the engagement of the upper cover 12 with the main cover 11 and further improving the ease of assembly and disassembly of the upper cover 12 relative to the main cover 11. At the same time, the setting of the raised rib 116 can also increase the overall structural strength and rigidity of the main cover 11 and avoid setting a snap-fit ​​structure on the main cover 11 for engaging with the buckle 123.

[0052] Specifically, raised ribs 116 are provided on the left and right sides and the front side wall of the positioning groove, and buckles 123 are connected to the left, right and front side plates 122 of the upper cover 12 to ensure the stability and reliability of the connection between the upper cover 12 and the main cover 11. The lower end of the side plate 122 abuts against the upper side of the raised ribs 116 to facilitate the assembly positioning and limiting of the two, and ensure assembly reliability.

[0053] The buckle 123 includes a connecting arm and a hook. The connecting arm is connected between the hook and the side plate 122. The rib 116 of the connecting arm faces the inside of the top groove, and the hook abuts against the lower side of the rib 116, thereby effectively ensuring the connection stability between the upper cover 12 and the main cover 11.

[0054] In one embodiment, the main hood 11 includes a vertical smoke-collecting section and a horizontal smoke-collecting section connected in a "7" shape. The vertical smoke-collecting section is vertically arranged, and the horizontal smoke-collecting section is horizontally arranged and connected to the top of the vertical smoke-collecting section. Smoke inlets 118 are provided on the front side of the vertical smoke-collecting section and the lower side of the horizontal smoke-collecting section, meaning the range hood is a top-and-side dual-suction range hood. The control mounting cavity is located inside the horizontal smoke-collecting section, meaning the smoke-collecting bottom plate 111 forms the bottom of the horizontal smoke-collecting section, and the front hood plate 112 forms the front side of the horizontal smoke-collecting section.

[0055] In another embodiment, the range hood can also be a top-mounted range hood, where the smoke collection base plate 111 forms the bottom of the main hood 11, and the fan module 6 is installed on the top of the smoke collection hood 1. In yet another embodiment, the range hood can also be an integrated stove, where the main hood 11 also includes connected vertical and horizontal smoke collection sections.

[0056] It is worth noting that this utility model does not limit the specific type and structure of the smoke collection hood 1, as long as the smoke collection hood 1 has a downward-facing smoke collection base plate 111 and a forward-facing hood front plate 112, so that the microphone 3 installed on the smoke collection base plate 111 is downward-facing, and the human body recognition module 22 located on the hood front plate 112 can be forward-facing.

[0057] In one embodiment, a mounting opening 1122 is provided at the center of the front panel 112 along the left-right direction. The control components of the control module are exposed through the mounting opening 1122 to facilitate user operation of the control components. To protect the mounting opening 1122, a front panel 5 is provided on the front panel 112. The front panel 5 covers both the mounting opening 1122 and the human body recognition hole 1121, and the front panel 5 is light-transmitting, facing the control components and the human body recognition hole 1121.

[0058] In one embodiment, the control module includes an electrically connected display interaction module and a main control board. The control components of the display interaction module are positioned corresponding to the mounting port. The audio recognition module 21 and the human body recognition module 22 are both connected to the display board within the display interaction module. Since the display interaction module is positioned close to the front panel 112, the audio recognition module 21 and the human body recognition module 22 are positioned even closer to the display interaction module. This facilitates the connection between the electrical components within the mounting cavity, shortens the length of the connecting lines, and improves the rationality of the layout.

[0059] The installation structure of the control module within the control mounting cavity can be set with reference to existing technology, which is not the focus of this utility model and will not be described in detail here.

[0060] like Figure 1 , Figure 5 and Figure 6As shown, in one embodiment, the sound pickup hole 1111 is installed on the smoke collection base plate 111 and located in the middle of the smoke collection hood 1 in the left-right direction, so as to facilitate the acquisition of sound from the stoves 100 on both sides. In other embodiments, the sound pickup hole 1111 may also be set to the left or right relative to the middle of the smoke collection hood 1.

[0061] Furthermore, the fan module 6 includes two fans 61 arranged side by side in the left-right direction. Both fans 61 are installed inside the smoke hood 1 and are communicatively connected to the control module. The microphone 1111 is located in the middle of the smoke hood 1 in the left-right direction. The ambient sound signal obtained by the microphone 3 can determine which side of the stove is ignited and started, so that the control module can control the operation of the corresponding fan 61 according to the signal picked up by the microphone 3.

[0062] In other embodiments, the fan module 6 may also be provided with only one fan 61, which may be located inside the smoke hood 1 or outside the smoke hood 1.

[0063] like Figure 5 and Figure 6 As shown, to improve the ease of installation of the microphone 3, an installation groove 117 is provided on the upper side of the smoke collection base plate 111. The bottom of the installation groove 117 is provided with a pickup hole 1111. The microphone 3 is installed in the installation groove 117. Thus, the installation groove 117 provides positioning for the installation of the microphone 3, ensuring the accuracy of the installation position of the microphone 3 and the reliability after installation.

[0064] In one embodiment, a protruding ring portion 113 is provided on the upper side of the smoke collection base plate 111. The protruding ring portion 113 and the smoke collection base plate 111 together form a mounting groove 117. This reduces the thickness of the smoke collection base plate 111 while ensuring the depth of the mounting groove 117, thereby ensuring the installation stability of the microphone 3. The shape of the mounting groove 117 is adapted to the shape of the microphone 3. Furthermore, the microphone 3 is bonded to the groove wall of the mounting groove 117 to reduce the installation difficulty of the microphone 3 and ensure the installation stability of the microphone 3.

[0065] The microphone 3 is connected to a connecting cable 4, which is electrically connected to the control module. This means that the microphone 3 and the audio recognition module 21 transmit signals via the connecting cable 4, thereby improving the reliability of signal transmission and reducing the impact of the external environment on signal transmission. In other embodiments, wireless communication can also be used between the microphone 3 and the audio recognition module 21.

[0066] like Figure 7 and Figure 8As shown, to simplify the structure of the recognition component 2, in one embodiment, the human body recognition component 2 is connected to the audio recognition component 2, so that the human body recognition component 2 and the audio recognition component 2 are integrated, reducing the footprint of the recognition component 2 and improving the overall assembly and disassembly performance of the recognition component 2. That is, a clearance opening 1221 is provided on the side plate portion 122 located on the front side.

[0067] The audio recognition component 2 includes a signal board with an audio recognition circuit. The human body recognition component 2 is electrically connected to the signal board, which has a signal transmission connector 23. The human body recognition module 22 and the signal transmission connector 23 are electrically connected through the circuit on the signal board. The signal transmission connector 23 is communicatively connected to the control module. That is, both the ambient sound signal acquired by the audio recognition module 21 and the detection signal acquired by the human body recognition module 22 are transmitted to the control module through the signal transmission connector 23.

[0068] To improve the installation reliability of the identification component 2 in the control mounting cavity, in one embodiment, a positioning slot 1141 is provided at the bottom of the control mounting cavity, and the lower end of the signal board is inserted into the positioning slot 1141. Thus, the installation of the identification component 2 can be positioned through the positioning slot 1141, ensuring that the human body identification module 22 can be accurately aligned with the identification hole 1121.

[0069] In one embodiment, a positioning boss 114 is provided on the bottom of the control mounting cavity, and a positioning slot 1141 is provided on the positioning boss 114. The positioning slot 1141 passes through the positioning boss 114 in the left and right direction, thereby improving the ease of opening the positioning slot 1141 and avoiding the setting of the positioning slot 1141 from affecting the local structural strength of the smoke hood 1.

[0070] In one embodiment, the human body recognition module 22 and the signal transmission connector 23 are located on opposite sides of the signal board, and the left and right sides of the positioning boss 114 abut against the human body recognition module 22 and the signal transmission connector 23, respectively. This ensures that the recognition component 2 is positioned in the left and right direction by cooperating with the positioning boss 114, thereby further improving the installation reliability of the recognition component 2.

[0071] To improve the installation stability of the identification component 2 inside the smoke hood 1, in one embodiment, a fixing part 115 protrudes from the rear side of the front plate 112 of the hood, and the fixing part 115 is detachably connected to the signal plate. Specifically, the fixing part 115 has a fastening threaded hole, and the signal plate has a through fastening through hole 211. The fixing part 115 and the signal plate are connected by a threaded connector passing through the fastening through hole 211 and the fastening threaded hole.

[0072] It is worth noting that the human body recognition module 22 can be an infrared recognition module or an image acquisition module. Any existing structure that can be used to identify the presence of a human body can be applied to this embodiment. This embodiment does not limit the specific structure of the human body recognition module 22.

[0073] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0074] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
