Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an electric heater. Background Technology

[0002] Taking baseboard heaters as an example, these heaters can be folded and unfolded to meet different user needs. Related technologies for baseboard heaters include mechanical control (power adjustment via knobs or toggle switches); electronic control via touch buttons (requiring manual operation by touching the buttons at the demo unit); remote control control (requiring manual operation using a remote control); Wi-Fi control (requiring operation via a mobile app); and online voice control (requiring other devices). Therefore, these technologies are not particularly convenient for controlling the heaters. Utility Model Content

[0003] In view of this, the present invention provides an electric heater to solve the problem of inconvenient control of electric heaters in related technologies.

[0004] This utility model provides an electric heater, comprising:

[0005] The shell has a partition structure inside, which can divide the shell into a first cavity and a second cavity, with the first cavity located above the second cavity;

[0006] The audio playback device is located inside the first cavity;

[0007] The voice acquisition device is located inside the second cavity;

[0008] The voice control module communicates with the voice playback device and the voice acquisition device.

[0009] Beneficial effects: The electric heater of this utility model is equipped with a voice control module, a voice acquisition device, and a voice playback device. The voice control module can adjust the electric heater according to the instructions collected by the voice acquisition device, and generate interactive instructions based on the instructions collected by the voice acquisition device, and play the interactive instructions through the voice playback device.

[0010] Therefore, users can adjust the electric heater without having to go near it and receive feedback from the heater, making it convenient to operate and providing a good user experience.

[0011] Based on this, some of the voice played by the voice playback device will propagate inside the casing. If this is captured by the voice acquisition device, it will cause the electric heater to repeatedly execute voice commands, thus affecting the user experience.

[0012] The electric heater in this embodiment of the application has a first cavity and a second cavity separated within the housing by a partition structure, and the voice acquisition device and the voice playback device are located in different cavities. Since the more obstacles a sound encounters during its propagation path, the more sound waves are absorbed, and the smaller the echo becomes, the longer the sound propagation path, the more it is consumed and absorbed, and the smaller the final sound wave becomes. Therefore, when the voice played by the voice playback device propagates in the first cavity, it can be blocked and absorbed by the partition structure. When the voice finally reaches the vicinity of the voice acquisition device, it will not be acquired by the voice acquisition device, avoiding phenomena such as crosstalk or reverberation, which helps to improve the user experience.

[0013] In one preferred embodiment, the housing includes a lower cavity assembly, the lower cavity assembly comprising:

[0014] The base has a second cavity inside it. A sound pickup hole is formed on one side wall of the base. The voice acquisition device is located at the sound pickup hole, and the acquisition side of the voice acquisition device faces the sound pickup hole.

[0015] The first bracket is detachably mounted at the microphone hole of the base and fitted over the voice acquisition device. The first bracket is interference-fitted with the side wall of the base.

[0016] Beneficial effects: With this setup, the first bracket wraps around the periphery of the voice acquisition device, exposing only the side of the voice acquisition device facing the pickup hole. This ensures that the voice acquisition device can only pick up sound from the direction of the pickup hole, while the pickup of sound from other directions (especially reflected sound) is weaker. Since reverberation sound usually comes from reflected sound from multiple directions, the setup of the first bracket can effectively reduce the occurrence of crosstalk.

[0017] Furthermore, since the first bracket and the side wall of the base are fitted with zero clearance, and the voice acquisition device is sealed and enclosed by the first bracket, when a simulated waterproof test is conducted, water is injected into the pickup hole of the base from different directions and fills the pickup hole, the water that is injected can overflow back to the pickup hole along the original path.

[0018] In one optional embodiment, the pickup hole includes a first hole segment and a second hole segment, the first hole segment being located outside the second hole segment, both the first hole segment and the second hole segment being horn-shaped, and the opening angle of the first hole segment being greater than the opening angle of the second hole segment.

[0019] Beneficial effects: Both the first and second hole sections are funnel-shaped, and the opening angle of the first hole section is greater than that of the second hole section, which can prevent water from entering the interior of the top cover through the sound pickup hole.

[0020] In one alternative embodiment, a buckle is provided on one of the base and the first bracket, and a slot is provided on the other of the base and the first bracket, and the buckle can engage with the slot.

[0021] Beneficial effects: With this setup, the operator can directly snap the first bracket to the base, making it simple and quick to connect the first bracket to the base.

[0022] In one alternative embodiment, the housing includes an upper cavity assembly, the upper cavity assembly comprising:

[0023] The upper cover plate forms a first cavity, and a first sound outlet is formed on one side wall of the upper cover plate. The voice playback device is located at the first sound outlet.

[0024] In one alternative implementation, the upper cavity assembly further includes:

[0025] The upper cover is placed on the upper cover plate and can block the first sound hole. The upper cover is provided with a second sound hole. The second sound hole and the first sound hole are located on the same side of the upper cavity assembly, and the second sound hole and the first sound hole are offset in the vertical plane.

[0026] Beneficial effect: With this configuration, the voice played by the voice playback device can be propagated outward through the first and second sound holes in sequence.

[0027] Furthermore, because the first and second sound outlets are offset in the vertical plane, when the electric heater is used in environments such as bathrooms, water entering the second sound outlet on the top cover from different angles can be blocked by the top cover and flow downwards, making it difficult for water to enter the casing and cause short circuits in the electronic components inside the electric heater.

[0028] In one alternative embodiment, the second sound hole is located below the first sound hole.

[0029] Beneficial effect: With this design, when water enters the second sound outlet on the top cover from different angles, it can be blocked by the top cover and flow downwards, making it less likely to enter the housing and cause short circuits in the electronic components inside the heater.

[0030] In one alternative implementation, there are multiple second sound holes arranged in an array.

[0031] Beneficial effects: By setting it up in this way, we can ensure that the second sound hole has a large total area while reducing the size of a single second sound hole, thereby reducing the risk of water entering the second sound hole while ensuring the playback volume of the voice playback device.

[0032] In one optional embodiment, the partition structure includes a bottom wall of an upper cover plate, the bottom wall of which is provided with a first drainage hole, and the lower cavity assembly includes:

[0033] The lower cover plate is located on the lower side of the base, and a second drain hole is provided on the lower cover plate, which is located below the first drain hole.

[0034] Beneficial effects: This design ensures that even if a small amount of water enters the upper cover, it will overflow through the first drain hole to the lower cover, and then be promptly drained out of the machine through the second drain hole on the lower cover. Furthermore, when a small amount of water enters the lower cover through the microphone hole, the second drain hole will also promptly drain the water out of the housing, preventing water accumulation inside the housing and avoiding short circuits in electrical components such as the tilt switch.

[0035] In one alternative embodiment, the lower cover plate is provided with a flow guiding structure, which is in communication with at least one second leakage hole.

[0036] Beneficial effects: By setting a second drainage hole and a flow guiding structure on the lower cover plate, when water enters the upper cover through the sound pickup hole, it leaks down through the first drainage hole and falls onto the lower cover plate. The flow guiding structure directs the water falling onto the lower cover plate to the second drainage hole, and it flows down through the second drainage hole, which can prevent water from accumulating on the lower cover plate.

[0037] In one alternative implementation, the electric heater further includes:

[0038] The second bracket includes a bracket body and at least one leg. The voice playback device is located inside the bracket body. The leg is connected to the bracket body. The bracket body is provided with a first connecting part, and the upper cover is provided with a second connecting part. The first connecting part can be detachably connected to the second connecting part.

[0039] In one alternative implementation, the electric heater further includes:

[0040] The rotating mechanism has a first cavity and a second cavity formed within it.

[0041] The first frame assembly and the second frame assembly are respectively located on both sides of the rotating mechanism and are rotatably connected to the rotating mechanism.

[0042] Beneficial effects: With this setup, during the use of the electric heater, the operator can rotate the first frame assembly and the second frame assembly to change the shape of the electric heater, thereby adapting the electric heater to the room layout.

[0043] For example, when the electric heater is used in a corner, the operator can drive the first frame assembly and the second frame assembly to rotate relative to the rotating mechanism so that the first frame assembly and the second frame assembly are set at an angle to suit the usage environment in the corner.

[0044] When the electric heater is applied to a straight wall, the operator can drive the first frame assembly and the second frame assembly to rotate relative to the rotating mechanism so that the first frame assembly and the second frame assembly are in a straight line.

[0045] After the electric heater is finished using it, the operator can drive the first frame assembly and the second frame assembly to rotate in opposite directions, thereby folding the electric heater and reducing the space occupied by the electric heater.

[0046] In one alternative embodiment, the outer periphery of the rotating mechanism is provided with a first region and a second region, the first frame assembly and the second frame assembly are rotatable within the range of the first region, and the voice acquisition device and the voice playback device are located within the second region of the rotating mechanism.

[0047] Beneficial effects: With this setup, no matter what angle the first and second frame components are rotated to, they will not obstruct the second area. Placing the voice acquisition device and the voice playback device in the second area ensures that the first and second frame components will neither hinder the voice acquisition device from acquiring the user's voice commands nor hinder the interactive voice emitted by the voice playback device.

[0048] In one alternative embodiment, the rotating mechanism includes:

[0049] The first bushing and the second bushing are located between the upper cavity and the lower cavity and are spaced apart in the horizontal direction. The first frame assembly is connected to the first bushing and the second frame assembly is connected to the second bushing.

[0050] In one alternative embodiment, the partition structure includes multiple layers of ribs disposed between the first cavity and the second cavity.

[0051] Beneficial effects: When the sound played by the voice playback device propagates within the first cavity, it encounters the obstruction of multiple layers of ribs, ultimately being absorbed and not captured by the voice acquisition device. Since the acoustic impedance difference between the plastic box and air is 3500 times, a difference of more than 20 times constitutes a total internal reflection interface. Whether sound waves transmit from air into the plastic or from the plastic into the air, the transmitted sound intensity is extremely low. Therefore, the multiple layers of ribs effectively reflect and absorb the sound played by the voice playback device, thereby effectively eliminating the reverberation caused by the voice playback device on the voice acquisition device and eliminating crosstalk from the voice playback device to the voice acquisition device.

[0090] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0091] Baseboard heaters can be folded and unfolded to meet different user needs. Related technologies for baseboard heaters include mechanical control (power adjustment via knobs or toggle switches); electronic control via touch buttons (requiring manual operation by touching buttons at the demo unit); remote control control (requiring manual operation using a remote control); Wi-Fi control (requiring operation via a mobile app); and online voice control (requiring other devices). Therefore, these technologies are not particularly convenient for controlling baseboard heaters.

[0092] Because the space in a folding baseboard heater is small, and the voice acquisition device 3 (microphone) is close to the voice broadcasting device, there will be crosstalk (that is, the voice broadcasting command is also captured by the voice acquisition device 3). After crosstalk, the entire heater will repeatedly execute the voice command. When the broadcasting sound of the speaker encounters some obstacles and produces an echo, the echo is captured by the microphone, which will also cause crosstalk. The sound broadcasting by the speaker will produce reverberation, which will affect the microphone. Thus, the accuracy of voice recognition will be affected.

[0093] Speech reverberation refers to the phenomenon of multiple echoes caused by reflections from walls, floors, ceilings, and other objects as sound propagates through a room or space. These reflected sounds mix with the direct sound, which can make the original sound unclear, affecting the auditory experience and the accuracy of speech recognition. In audio processing and voice communication technologies, dereverberation techniques are often used to reduce or eliminate these adverse effects in order to improve sound quality and clarity.

[0094] In addition, the device needs to have a microphone 1023 to collect voice commands and a sound output hole to enable the voice broadcast device to interact with the user. However, both the microphone 1023 and the sound output hole are prone to water ingress, causing the device to fail to meet waterproof requirements.

[0095] The folding baseboard can be folded from 0° to 180°. When folded at 0°, the angle formed by the left and right heating components is 0°. At this time, the microphone hole 1023 and the sound outlet hole must not be blocked, otherwise the offline voice function will fail. The microphone hole 1023 collects voice commands transmitted through the air, and the voice commands broadcast by the sound outlet hole are also transmitted to the user through the air. Therefore, the microphone hole 1023 and the sound outlet hole must not be blocked and need to be designed to face outwards from the baseboard heater. This results in less space to choose from on the heater.

[0096] If the diameter of the microphone hole 1023 is too small or the number of holes is too few, the microphone will not be able to pick up voice commands. If the diameter of the sound outlet hole is too small or the number of holes is too few, the voice broadcasting that interacts with the user will be trapped inside the device and cause greater reverberation. If the diameter of the microphone hole 1023 and the number of sound outlet holes are too large, the device will not be waterproof.

[0097] The following is combined with Figures 1 to 18 The following describes embodiments of the present invention.

[0098] According to an embodiment of this utility model, an electric heater is provided, including a housing 1, a voice playback device 2, a voice acquisition device 3, and a voice control module. The housing 1 has a partition structure that divides the housing 1 into a first cavity 1011 and a second cavity, with the first cavity 1011 located above the second cavity. The voice playback device 2 is located within the first cavity 1011. The voice acquisition device 3 is located within the second cavity. The voice control module is communicatively connected to the voice playback device 2 and the voice acquisition device 3.

[0099] The electric heater of this invention includes a voice control module, a voice acquisition device 3, and a voice playback device 2. The voice control module can adjust the electric heater according to the instructions collected by the voice acquisition device 3, and generate interactive instructions based on the instructions collected by the voice acquisition device 3, which are then played back through the voice playback device 2.

[0100] Therefore, users can adjust the electric heater without having to go near it and receive feedback from the heater, making it convenient to operate and providing a good user experience.

[0101] Based on this, some of the voice played by the voice playback device 2 will propagate inside the casing 1. If it is collected by the voice acquisition device 3, it will cause the electric heater to repeatedly execute voice commands, thereby affecting the user experience.

[0102] The electric heater in this embodiment of the application has a first cavity 1011 and a second cavity separated within the housing 1 by a partition structure. The voice acquisition device 3 and the voice playback device 2 are placed in different cavities. Since the more obstacles a sound encounters during its propagation path, the more sound waves are absorbed, and the smaller the echo becomes, the longer the sound propagation path, the more it is consumed and absorbed, and the smaller the sound wave becomes. Therefore, when the voice played by the voice playback device 2 propagates in the first cavity 1011, it can be blocked and absorbed by the partition structure. When the voice finally reaches the vicinity of the voice acquisition device 3, it will not be acquired by the voice acquisition device 3, thus avoiding phenomena such as crosstalk or reverberation, which helps to improve the user experience.

[0103] In one embodiment, the voice acquisition device 3 is preferably, but not limited to, a microphone. The voice playback device 2 is preferably, but not limited to, a speaker.

[0104] In one embodiment, the housing 1 includes a lower cavity assembly 102, which includes a base 1021 and a first support 1022.

[0105] The base 1021 contains a second cavity, and a pickup hole 1023 is formed on one side wall of the base 1021. The voice acquisition device 3 is located at the pickup hole 1023, with the acquisition side of the voice acquisition device 3 facing the pickup hole 1023. A first bracket 1022 is detachably mounted at the pickup hole 1023 of the base 1021 and is fitted over the voice acquisition device 3. The first bracket 1022 is interference-fitted with the side wall of the base 1021.

[0106] By setting it up in this way, such as Figure 4 and Figure 5 As shown, the first bracket 1022 can wrap around the outer periphery of the voice acquisition device 3, exposing only the side of the voice acquisition device 3 facing the pickup hole 1023, ensuring that the voice acquisition device 3 can only pick up sound from the direction of the pickup hole 1023, while the pickup of sound from other directions (especially reflected sound) is weaker. Since reverberation sound usually comes from reflected sound from multiple directions, the setting of the first bracket 1022 can effectively reduce the occurrence of crosstalk.

[0107] Furthermore, since the first bracket 1022 and the side wall of the base 1021 are in a zero-gap fit, and the voice acquisition device 3 is sealed and wrapped by the first bracket 1022, when a simulated waterproof test is conducted, water is injected into the pickup hole 1023 of the base 1021 from different directions and fills the pickup hole 1023, the water that is injected can overflow back to the pickup hole 1023 along the original path.

[0108] In one embodiment, the base 1021 has a top wall and a first side wall connected to the top wall, and a first bracket 1022 is detachably connected to the upper part of the base 1021. This arrangement increases the height of the voice acquisition device 3, preventing it from being positioned too low and affecting the voice acquisition effect.

[0109] In one embodiment, such as Figure 5 As shown, the pickup hole 1023 includes a first hole segment 10231 and a second hole segment 10232. The first hole segment 10231 is located outside the second hole segment 10232. Both the first hole segment 10231 and the second hole segment 10232 are trumpet-shaped, and the opening angle of the first hole segment 10231 is greater than the opening angle of the second hole segment 10232.

[0110] Both the first hole segment 10231 and the second hole segment 10232 are funnel-shaped, and the opening angle of the first hole segment 10231 is greater than the opening angle of the second hole segment 10232, which can prevent water from entering the interior of the top cover 1013 through the sound pickup hole 1023.

[0111] In one embodiment, such as Figure 3 As shown, one of the base 1021 and the first bracket 1022 is provided with a buckle 10221, and the other of the base 1021 and the first bracket 1022 is provided with a slot, and the buckle 10221 can be engaged with the slot.

[0112] With this setup, the operator can directly connect the first bracket 1022 to the base 1021, making it simple and quick to connect the first bracket 1022 to the base 1021.

[0113] As an alternative implementation, the first bracket 1022 may also be connected to the base 1021 by means of bonding, riveting, bolting or magnetic connection.

[0114] In one embodiment, the upper part of the base 1021 is provided with one of a slot and a buckle, and the first bracket 1022 is provided with the other of a slot and a buckle. This arrangement ensures that, after assembly, the first bracket is positioned higher, thereby increasing the height of the voice acquisition device and preventing the voice acquisition effect from being affected by the device being too low.

[0115] In one embodiment, such as Figure 7 As shown, the housing 1 includes an upper cavity assembly 101, which includes an upper cover plate 1012. A first cavity 1011 is formed inside the upper cover plate 1012, and a first sound outlet 10121 is formed on one side wall of the upper cover plate 1012. The voice playback device 2 is located at the first sound outlet 10121.

[0116] In one embodiment, such as Figure 8As shown, the upper cavity assembly 101 also includes an upper cover 1013.

[0117] The upper cover 1013 is fitted onto the upper cover plate 1012 and can block the first sound outlet 10121. The upper cover 1013 is provided with a second sound outlet 10131. The second sound outlet 10131 and the first sound outlet 10121 are located on the same side of the upper cavity assembly 101, and the second sound outlet 10131 and the first sound outlet 10121 are offset from each other in the vertical plane (see...). Figure 8 ).

[0118] With this configuration, the voice played by the voice playback device 2 can be transmitted outward through the first sound outlet 10121 and the second sound outlet 10131 in sequence.

[0119] Furthermore, since the first sound outlet 10121 and the second sound outlet 10131 are offset in the vertical plane, when the electric heater is used in environments such as bathrooms, water can be blocked by the top cover plate 1012 after entering the second sound outlet 10131 on the top cover 1013 from different angles and flow downwards, making it difficult to enter the interior of the housing 1 and cause short circuits in the electronic components inside the electric heater.

[0120] In one embodiment, the second sound outlet 10131 is located below the first sound outlet 10121.

[0121] With this configuration, when water is injected from different angles onto the second sound outlet 10131 on the top cover 1013, it can be blocked by the top cover plate 1012 and flow downwards, making it difficult to enter the interior of the housing 1 and cause a short circuit in the electronic components inside the electric heater.

[0122] As an alternative implementation, the second sound hole 10131 may also be located on one side of the first sound hole 10121 along the horizontal direction.

[0123] In one embodiment, such as Figure 9 As shown, there are multiple second sound holes 10131, which are arranged in an array.

[0124] By setting it up in this way, it is possible to ensure that the second sound outlet 10131 has a large total area while reducing the size of a single second sound outlet 10131, thereby reducing the risk of water entering the second sound outlet 10131 while ensuring the playback volume of the voice playback device 2.

[0125] It should be noted that, in this embodiment of the application, the number of second sound holes 10131 is not limited.

[0126] For example, in an optional embodiment, there are four rows of second sound holes 10131, with seven second sound holes 10131 in each row.

[0127] In one embodiment, the upper cavity assembly 101 further includes a display panel 1015, a display board 1016, and a main board 1017.

[0128] like Figure 10 As shown, the display panel 1015 is located on the upper cover 1013. The display board 1016 and the main board 1017 are located below the upper cover 1013. The voice control module is located on the main board 1017, and the voice playback device 2 is communicatively connected to the main board 1017.

[0129] In one embodiment, the partition structure includes the bottom wall of an upper cover plate 1012. A first drainage hole 10122 is provided on the bottom wall of the upper cover plate 1012, and the lower cavity assembly 102 includes a lower cover plate 1024. The lower cover plate 1024 is located below the base 1021, and a second drainage hole 10241 is provided on the lower cover plate 1024, located below the first drainage hole 10122.

[0130] With this design, even if a small amount of water enters the upper cover plate 1012, it can overflow through the first drain hole 10122 to the lower cover plate 1024, and then be promptly drained out of the machine through the second drain hole 10241 on the lower cover plate 1024. Furthermore, when a small amount of water enters the lower cover plate 1024 through the sound pickup hole 1023, the second drain hole 10241 can also promptly drain the water out of the housing 1, preventing water accumulation inside the housing 1 and avoiding short circuits in electrical components such as the tilt switch 8.

[0131] In one embodiment, a stand 1026 is provided below the lower cover plate 1024.

[0132] In one embodiment, such as Figure 3 As shown, a tilt switch 8 is provided on the lower cover plate 1024.

[0133] With this design, when the electric heater tipps over, the tipping switch 8 can control the power supply to the electric heater to stop, thereby avoiding any danger.

[0134] In one embodiment, the lower cover plate 1024 is provided with a flow guiding structure 10242, which is connected to at least one second water leakage hole 10241.

[0135] By providing a second drain hole 10241 and a flow guiding structure 10242 in the lower cover plate 1024, when water enters the interior of the upper cover 1013 through the sound pickup hole 1023, it leaks down through the first drain hole 10122 and falls onto the lower cover plate 1024. The flow guiding structure 10242 guides the water falling onto the lower cover plate 1024 to the second drain hole 10241, and then flows down through the second drain hole 10241, which can prevent water accumulation on the lower cover plate 1024.

[0136] In one embodiment, the flow guiding structure 10242 is a flow guiding channel formed by flow guiding ribs. The flow guiding channel can guide water to flow out through the second drain hole 10241 and prevent water from contacting electrical components.

[0137] In one embodiment, the electric heater also includes a second bracket 1014.

[0138] like Figure 12 As shown, the second bracket 1014 includes a bracket body 10141 and at least one support leg 10142. The voice playback device 2 is disposed inside the bracket body 10141. The support leg 10142 is connected to the bracket body 10141. The bracket body 10141 is provided with a first connecting part, and the upper cover plate 1012 is provided with a second connecting part. The first connecting part can be detachably connected to the second connecting part.

[0139] With this configuration, the second bracket 1014 can be connected to the upper cover plate 1012 via the support leg 10142, thus making it more suitable for complex installation environments within the upper cover plate 1012. The first and second connecting parts are preferably, but not limited to, connectable components, bolted connection components, or magnetic connection components.

[0140] In one embodiment, a limiting rib is formed on one of the second bracket 1014 and the upper cover plate 1012, and a limiting groove is formed on the other of the second bracket 1014 and the upper cover plate 1012, and the limiting rib can be inserted into the limiting groove.

[0141] In one embodiment, the second bracket 1014 and the sidewall of the upper cover plate 1012 are spaced apart in the horizontal direction. With this arrangement, an air cavity can be formed between the sound output side of the voice playback device 2 and the first sound output hole 10121, so as to avoid the misalignment of the first sound output hole 10121 and the second sound output hole 10131 affecting the sound output effect of the voice playback device 2.

[0142] Therefore, the second bracket 1014 in this embodiment allows the first sound outlet 10121 and the second sound outlet 10131 to be misaligned to prevent water from flowing into the housing 1 and to avoid affecting the sound output effect of the voice playback device 2.

[0143] In one embodiment, the electric heater further includes a rotating mechanism 4, a first frame assembly 5, and a second frame assembly 6.

[0144] The first cavity 1011 and the second cavity are formed within the rotating mechanism 4. The first frame assembly 5 and the second frame assembly 6 are respectively disposed on both sides of the rotating mechanism 4 and are rotatably connected to the rotating mechanism 4.

[0145] By setting it up in this way, such as Figure 1As shown, during the use of the electric heater, the operator can rotate the first frame assembly 5 and the second frame assembly 6 to change the shape of the electric heater, thereby making the electric heater adapt to the indoor layout.

[0146] For example, when the electric heater is used in a corner, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate relative to the rotating mechanism 4 so that the first frame assembly 5 and the second frame assembly 6 are set at an angle to suit the usage environment in the corner.

[0147] When the electric heater is applied to a straight wall, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate relative to the rotating mechanism 4 so that the first frame assembly 5 and the second frame assembly 6 are in a straight line.

[0148] When the electric heater is finished being used, such as Figure 16 As shown, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate in opposite directions, thereby folding the electric heater and reducing the space occupied by the electric heater.

[0149] In one embodiment, such as Figure 15 and Figure 17 As shown, the outer periphery of the rotating mechanism 4 is provided with a first region 401 and a second region 402. The first frame assembly 5 and the second frame assembly 6 can rotate within the range of the first region 401. The voice acquisition device 3 and the voice playback device 2 are located in the second region 402 of the rotating mechanism 4.

[0150] With this setup, no matter what angle the first frame component 5 and the second frame component 6 are rotated to, they will not obstruct the second area 402. By placing the voice acquisition device 3 and the voice playback device 2 within the second area 402, it can be ensured that the first frame component 5 and the second frame component 6 will neither hinder the voice acquisition device 3 from acquiring the voice commands issued by the user, nor hinder the interactive voice emitted by the voice playback device 2.

[0151] In one recent embodiment, such as Figure 15 As shown, the rotating mechanism 4 includes a first bushing 403 and a second bushing 404.

[0152] The first bushing 403 and the second bushing 404 are disposed between the upper cavity and the lower cavity and are spaced apart in the horizontal direction. The first frame assembly 5 is connected to the first bushing 403 and the second frame assembly 6 is connected to the second bushing 404, thereby realizing the rotational connection between the first frame assembly 5 and the second frame assembly 6 and the rotating mechanism 4.

[0153] The upper cavity assembly 101 and the lower cavity assembly 102 are preferably, but not limited to, connected to each other by screws.

[0154] In one embodiment, the first frame assembly 5 and the second frame assembly 6 are respectively connected to the first bushing 403 and the second bushing 404 via decorative shells.

[0155] In one embodiment, such as Figure 18 As shown, the partition structure includes multiple layers of ribs 7 disposed between the first cavity 1011 and the second cavity.

[0156] When the sound played by the voice playback device 2 propagates within the first cavity 1011, it encounters the obstruction of multiple layers of ribs 7, and is ultimately absorbed, preventing it from being collected by the voice acquisition device 3. Since the acoustic impedance difference between the plastic box and the air is 3500 times, a difference of more than 20 times constitutes a total internal reflection interface. Whether sound waves travel from the air into the plastic or vice versa, the transmitted sound intensity is extremely low. Therefore, the multiple layers of ribs 7 effectively reflect and absorb the sound played by the voice playback device 2, thereby effectively eliminating the reverberation caused by the sound played by the voice playback device 2 on the voice acquisition device 3, and eliminating the crosstalk effect of the sound broadcast by the voice playback device 2 on the voice acquisition device 3.

[0157] The upper cover plate 1012 includes a bottom wall and side walls, and the base 1021 includes a top wall and a bottom wall. The multi-layer ribs 7 preferably include, but are not limited to, the bottom wall of the upper cover plate 1012, the top wall of the base 1021, and the bushing, etc.

[0158] In one embodiment, a plurality of raised ribs are formed on the bottom wall of the top cover plate 1012 and / or the top wall of the base 1021.

[0159] In one embodiment, the electric heater may be a baseboard heater.

[0160] In summary, the electric heater of this embodiment has a voice recognition function, allowing users to adjust the heater without having to walk near it and receive adjustment feedback. This makes operation convenient and provides a good user experience. Furthermore, the voice played by the voice playback device 2 is obstructed and absorbed by the separation structure as it propagates within the first cavity 1011. When the voice finally reaches the vicinity of the voice acquisition device 3, it will not be captured by the voice acquisition device 3, avoiding crosstalk or reverberation, thus enhancing the user experience.

[0161] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
