Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an electric heater. Background Art

[0002] Taking the baseboard heater as an example, the electric heater can be folded and unfolded to meet the different requirements of users. The control methods of baseboard heaters in related technologies include mechanical type (adjusting power through knobs or wave switches); touch button electronic type (also need to go to the prototype and touch the buttons manually to operate); remote control type (need to use a remote control and manually press the buttons on the remote control to operate); WIFI control (need to use the mobile phone APP to operate); online voice (need to use other devices to achieve). Therefore, the related technology is not convenient for controlling electric heaters. Summary of the invention

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

[0004] The present invention provides an electric heater, comprising:

[0005] A housing, wherein a partition structure is provided in the housing, and the partition structure can separate a first cavity and a second cavity in the housing, wherein the first cavity is provided above the second cavity;

[0006] A voice playback device is disposed in the first cavity;

[0007] A voice collection device is arranged in the second cavity;

[0008] The voice master control module is connected to the voice playback module and the voice collection module for communication.

[0009] Beneficial effects: The electric heater of the present invention is provided with a voice main control module, a voice acquisition device and a voice playback device. The voice main control module can adjust the electric heater according to the instructions collected by the voice acquisition device, generate interactive instructions according to the instructions collected by the voice acquisition device, and play the interactive instructions through the voice playback device.

[0010] Therefore, the user does not need to go near the electric heater to adjust the electric heater and can obtain adjustment feedback information of the electric heater. The operation is convenient and the user experience is good.

[0011] On this basis, part of the voice played by the voice playback device will be transmitted inside the shell. If it is collected by the voice collection device, it will cause the electric heater to repeatedly execute voice commands, thereby affecting the user experience.

[0012] The electric heater of the embodiment of the present application is separated into a first cavity and a second cavity by a partition structure in the shell, and the voice collection device and the voice playback device are arranged in different cavities. The more obstacles the sound encounters during the propagation path, the more sound waves are absorbed, and the echo will become smaller and smaller. The longer the sound propagation path is, the more it is consumed and absorbed, and finally the sound wave will be smaller. Therefore, the voice played by the voice playback device can be hindered and absorbed by the partition structure when propagating in the first cavity. When the voice is finally transmitted to the vicinity of the voice collection device, it will not be collected by the voice collection device, thereby avoiding the occurrence of phenomena such as crosstalk or reverberation, and helping to improve the user experience.

[0013] In a selected embodiment, the housing includes a lower cavity assembly, and the lower cavity assembly includes:

[0014] A base, a second cavity is formed in the base, a sound pickup hole is formed on one side wall of the base, a voice collection device is arranged at the sound pickup hole, and a collection side of the voice collection device is arranged toward the sound pickup hole;

[0015] The first bracket is detachably arranged at the sound pickup hole of the base and sleeved outside the voice collection device. The first bracket is interference-fitted with the side wall of the base.

[0016] Beneficial effect: Through such a configuration, the first bracket wraps the periphery of the voice collection module, exposing only one side of the voice collection module facing the sound pickup hole, ensuring that the voice collection module can only pick up sounds from the direction of the sound pickup hole, while the pickup of sounds from other directions (especially reflected sounds) can be weaker. Since reverberation sounds are usually reflected sounds from multiple directions, the configuration of the first bracket can effectively reduce the occurrence of crosstalk.

[0017] On this basis, since the first bracket and the side wall of the base are matched with zero clearance, and the voice collection device is sealed and wrapped by the first bracket, when the simulated waterproof test is tested, water is injected into the sound pickup hole of the base from different directions and blocks the sound pickup hole. The injected water flow can overflow back toward the original path of the sound pickup hole.

[0018] In an optional embodiment, the sound pickup hole includes a first hole segment and a second hole segment, the first hole segment is located outside the second hole segment, the first hole segment and the second hole segment are both trumpet-shaped, and the opening angle of the first hole segment is greater than the opening angle of the second hole segment.

[0019] Beneficial effect: The first hole segment and the second hole segment are both trumpet-shaped, and the opening angle of the first hole segment is greater than the opening angle of the second hole segment, which can prevent water from entering the interior of the upper cover through the sound pickup hole.

[0020] In an optional 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 be snap-connected with the slot.

[0021] Beneficial effect: Through such an arrangement, the operator can directly buckle the first bracket with the base, and can simply and quickly connect the first bracket to the base.

[0022] In an optional embodiment, the housing includes an upper cavity assembly, and the upper cavity assembly includes:

[0023] An upper cover plate is provided with a first cavity formed in the upper cover plate, a first sound outlet hole is formed on a side wall of the upper cover plate, and a voice playing module is arranged at the first sound outlet hole.

[0024] In an optional embodiment, the upper cavity assembly further includes:

[0025] The upper cover is arranged on the upper cover plate and can cover the first sound outlet hole. The upper cover is provided with a second sound outlet hole. The second sound outlet hole and the first sound outlet hole are arranged on the same side of the upper cavity component, and the second sound outlet hole and the first sound outlet hole are staggered in the vertical plane.

[0026] Beneficial effect: Through such an arrangement, the voice played by the voice playback device can be transmitted outward through the first sound outlet hole and the second sound outlet hole in sequence.

[0027] Because the first sound hole and the second sound hole are staggered in the vertical plane, when the electric heater is used in a bathroom or other environment, water can be blocked by the upper cover after being incident on the second sound hole on the upper cover from different angles and flow downward, and it is not easy to enter the interior of the shell and cause a short circuit in the electronic components in the electric heater.

[0028] In an optional implementation, the second sound outlet hole is arranged below the first sound outlet hole.

[0029] Beneficial effect: Through such an arrangement, when water is incident on the second sound outlet on the upper cover from different angles, it can be blocked by the upper cover and flow downward, and is not easy to enter the interior of the shell and cause a short circuit in the electronic components in the electric heater.

[0030] In an optional implementation, there are multiple second sound outlet holes, and they are distributed in an array.

[0031] Beneficial effect: Through such a configuration, it is possible to ensure that the second sound outlet holes have a larger total area while reducing the size of a single second sound outlet hole, thereby reducing the risk of water ingress at the second sound outlet holes while ensuring the playback volume of the voice playback device.

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

[0033] The lower cover plate is arranged on the lower side of the base, and a second water leakage hole is arranged on the lower cover plate, and the second water leakage hole is arranged below the first water leakage hole.

[0034] Beneficial effect: Through such arrangement, even if a small amount of water flows into the upper cover, it can overflow to the lower cover through the first leakage hole in sequence, and the water can be discharged to the outside of the whole machine in time through the second leakage hole arranged on the lower cover. In addition, when a small amount of water flows into the lower cover through the sound pickup hole, the second leakage hole can also discharge the water from the leakage hole to the outside of the shell in time, avoiding water accumulating in the shell and causing short circuit of electrical components such as the tipping switch.

[0035] In an optional embodiment, a flow guiding structure is provided on the lower cover plate, and the flow guiding structure is connected to at least one second water leakage hole.

[0036] Beneficial effect: By arranging a second water leakage hole and a guide structure on the lower cover plate, when water enters the upper cover through the sound pickup hole, it leaks downward through the first water leakage hole and falls on the lower cover plate. The guide structure guides the water falling on the lower cover plate to the second water leakage hole, and flows downward through the second water leakage hole, thereby avoiding water accumulation on the lower cover plate.

[0037] In an optional embodiment, the electric heater further comprises:

[0038] The second bracket includes a bracket body and at least one support leg. The voice playback device is arranged in the bracket body. The support leg is connected to the bracket body. A first connecting part is arranged on the bracket body. A second connecting part is arranged on the upper cover plate. The first connecting part can be detachably connected to the second connecting part.

[0039] In an optional embodiment, the electric heater further comprises:

[0040] A rotating mechanism, wherein the first cavity and the second cavity are formed in the rotating mechanism;

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

[0042] Beneficial effect: Through such an arrangement, 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 making the electric heater adapt to the indoor layout.

[0043] Exemplarily, 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 arranged at an angle to adapt to the use environment in the corner.

[0044] When the electric heater is applied to a vertical 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] When the electric heater is finished being used, the operator can drive the first frame assembly and the second frame assembly to rotate toward each other, thereby folding the electric heater and reducing the space occupied by the electric heater.

[0046] In an optional embodiment, the outer periphery of the rotating mechanism is provided with a first area and a second area, the first frame assembly and the second frame assembly can rotate within the range of the first area, and the voice collection device and the voice playback device are arranged in the second area of ​​the rotating mechanism.

[0047] Beneficial effect: Through such an arrangement, no matter what angle the first frame component and the second frame component are rotated to, the second area will not be blocked. The voice collection device and the voice playback device are arranged in the second area, which can ensure that the first frame component and the second frame component will neither hinder the voice collection device from collecting the voice commands issued by the user, nor hinder the interactive voice issued by the voice playback device.

[0048] In an optional embodiment, the rotating mechanism includes:

[0049] The first sleeve and the second sleeve are arranged between the upper cavity and the lower cavity and are arranged at intervals in the horizontal direction. The first frame assembly is connected to the first sleeve, and the second frame assembly is connected to the second sleeve.

[0050] In an optional embodiment, the partition structure includes a plurality of layers of ribs disposed between the first cavity and the second cavity.

[0051] Beneficial effect: When the sound played by the voice playback device propagates in the first cavity, it will encounter the obstruction of the multi-layer ribs, and finally the sound will be absorbed and will not be collected by the voice collection device. Since the acoustic impedance of the plastic box and the air differs by 3500 times, as long as the acoustic impedance differs by more than 20 times, it is a total reflection interface; whether the sound wave is transmitted from the air to the plastic, or from the plastic to the air, the sound intensity that can be transmitted is extremely small; therefore, the multi-layer ribs can effectively reflect and absorb the sound played by the voice playback device, and then effectively eliminate the influence of the reverberation generated by the sound played by the voice playback device on the voice collection device, and eliminate the influence of the sound broadcast by the voice playback device on the voice collection device.

[0090] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0091] The skirting board heater can be folded and unfolded to meet the different requirements of users. The control methods of skirting board heaters in related technologies include mechanical type (adjusting power through knobs or wave switches); touch button electronic type (also need to go to the prototype and touch the buttons manually to operate); remote control type (need to use a remote control and manually press the buttons on the remote control to operate); WIFI control (need to use a mobile phone APP to operate); online voice (need to use other devices to achieve). Therefore, the related technology is not convenient for controlling skirting board heaters.

[0092] Since the space of the folding skirting board heater is small and the distance between the voice collection device 3 (microphone) and the voice broadcasting device is close, there will be crosstalk (that is, the voice broadcast instructions are collected by the voice collection device 3); the crosstalk will cause the electric heater to repeatedly execute the voice instructions; when the broadcast sound of the speaker encounters some obstacles and produces an echo, the echo is collected by the microphone, which will also cause crosstalk; the sound broadcast by the speaker will produce reverberation and affect the microphone; thereby affecting the accuracy of voice recognition.

[0093] Voice reverberation refers to the phenomenon of multiple echoes caused by reflections from walls, floors, ceilings and other objects when sound propagates in a room or space. These reflected sounds are mixed with the direct sound, which can cause the original sound to become unclear, affecting the auditory experience and the accuracy of speech recognition. In audio processing and voice communication technology, dereverberation technology is usually required to reduce or eliminate these adverse effects to improve the quality and clarity of the sound.

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

[0095] The foldable skirting board 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 sound pickup hole 1023 and the sound output hole cannot be blocked, otherwise the offline voice function will fail. The sound pickup hole 1023 collects voice commands transmitted through the air, and the voice commands broadcast by the sound output hole are also transmitted to the user through the air. Therefore, the sound pickup hole 1023 and the sound output hole cannot be blocked and need to be designed toward the outside of the skirting board heater. This results in less room for choice on the heater.

[0096] When the diameter of the sound pickup holes 1023 is small or the number is small, the microphone will not be able to collect voice commands; if the diameter of the sound output holes is small or the number is small, the broadcast voice sound for interacting with the user will be trapped inside the entire device and cause greater reverberation; and if the diameter of the sound pickup holes 1023 and the sound output holes are large and the number is large, the entire device will not be waterproof.

[0097] Combine the following Figures 1 to 18 , describing an embodiment of the present invention.

[0098] According to an embodiment of the present invention, an electric heater is provided, comprising a housing 1, a voice playback device 2, a voice collection device 3 and a voice main control module. A partition structure is provided in the housing 1, and the partition structure can separate a first cavity 1011 and a second cavity in the housing 1, and the first cavity 1011 is arranged above the second cavity. The voice playback device 2 is arranged in the first cavity 1011. The voice collection device 3 is arranged in the second cavity. The voice main control module is connected to the voice playback module and the voice collection module for communication.

[0099] The electric heater of the present invention is provided with a voice main control module, a voice acquisition device 3 and a voice playback device 2. The voice main control module can adjust the electric heater according to the instructions collected by the voice acquisition device 3, and generate interactive instructions according to the instructions collected by the voice acquisition device 3, and play the interactive instructions through the voice playback device 2.

[0100] Therefore, the user does not need to go near the electric heater to adjust the electric heater and can obtain adjustment feedback information of the electric heater. The operation is convenient and the user experience is good.

[0101] On this basis, part of the voice played by the voice playback device 2 will be transmitted inside the housing 1. If it is collected by the voice collection device 3, it will cause the electric heater to repeatedly execute voice commands, thereby affecting the user experience.

[0102] The electric heater of the embodiment of the present application separates the first cavity 1011 and the second cavity by a partition structure in the shell 1, and arranges the voice collection device 3 and the voice playback device 2 in different cavities. The more obstacles the sound encounters during the propagation path, the more sound waves are absorbed, and the echo will become smaller and smaller. The longer the sound propagation path is, the more it is consumed and absorbed, and finally the sound wave will be smaller. Therefore, the voice played by the voice playback device 2 can be hindered and absorbed by the partition structure when propagating in the first cavity 1011. When the voice is finally transmitted to the vicinity of the voice collection device 3, it will not be collected by the voice collection device 3, thereby avoiding the occurrence of phenomena such as crosstalk or reverberation, which helps to improve the user experience.

[0103] In one embodiment, the voice collection 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 , and the lower cavity assembly 102 includes a base 1021 and a first bracket 1022 .

[0105] A second cavity is formed in the base 1021, a sound pickup hole 1023 is formed on a side wall of the base 1021, and the voice collection device 3 is arranged at the sound pickup hole 1023, and the collection side of the voice collection device 3 is arranged toward the sound pickup hole 1023. The first bracket 1022 is detachably arranged at the sound pickup hole 1023 of the base 1021, and is sleeved outside the voice collection device 3, and the first bracket 1022 is interference fit with the side wall of the base 1021.

[0106] By setting it up like this, Figure 4 and Figure 5 As shown, the first bracket 1022 can wrap the periphery of the voice collection module, exposing only one side of the voice collection module facing the sound pickup hole 1023, ensuring that the voice collection module can only pick up sounds from the direction of the sound pickup hole 1023, while the sound from other directions (especially reflected sounds) can be picked up weakly. Since reverberation sounds are usually reflected sounds from multiple directions, the setting of the first bracket 1022 can effectively reduce the occurrence of crosstalk.

[0107] On this basis, since the first bracket 1022 and the side wall of the base 1021 are matched with zero clearance, and the voice collection device 3 is sealed and wrapped by the first bracket 1022, when the simulated waterproof test is tested, water is injected into the sound pickup hole 1023 of the base 1021 from different directions and blocks the sound pickup hole 1023, the injected water flow can overflow back toward the sound 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 the first bracket 1022 is detachably connected to the upper portion of the base 1021. By such a configuration, the height of the voice collection module can be increased to avoid the position of the voice collection module being too low to affect the voice collection effect.

[0109] In one embodiment, Figure 5 As shown, the sound 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. The first hole segment 10231 and the second hole segment 10232 are both 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] The first hole section 10231 and the second hole section 10232 are both trumpet-shaped, and the opening angle of the first hole section 10231 is greater than the opening angle of the second hole section 10232 , which can prevent water from entering the interior of the upper cover 1013 through the sound pickup hole 1023 .

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

[0112] Through such a configuration, the operator can directly buckle the first bracket 1022 and the base 1021 , and can simply and quickly connect the first bracket 1022 to the base 1021 .

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

[0114] In one embodiment, one of a slot and a buckle is provided on the upper portion of the base 1021, and the other of the slot and the buckle is provided on the first bracket 1022. By such a configuration, after assembly, the position of the first bracket can be higher, and thus the height of the voice collection device can be higher, so as to avoid the voice collection effect being affected by the voice collection device being too low.

[0115] In one embodiment, Figure 7 As shown, the housing 1 includes an upper cavity assembly 101, and the upper cavity assembly 101 includes an upper cover plate 1012. A first cavity 1011 is formed in the upper cover plate 1012, and a first sound outlet hole 10121 is formed on a side wall of the upper cover plate 1012, and a voice playback module is disposed at the first sound outlet hole 10121.

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

[0117] The upper cover 1013 is disposed on the upper cover plate 1012 and can cover the first sound outlet hole 10121. The upper cover 1013 is provided with a second sound outlet hole 10131. The second sound outlet hole 10131 and the first sound outlet hole 10121 are disposed on the same side of the upper cavity assembly 101, and the second sound outlet hole 10131 and the first sound outlet hole 10121 are staggered in the vertical plane (see Figure 8 ).

[0118] By such configuration, the voice played by the voice playing device 2 can be transmitted outward through the first sound outlet hole 10121 and the second sound outlet hole 10131 in sequence.

[0119] Furthermore, since the first sound hole 10121 and the second sound hole 10131 are staggered in the vertical plane, when the electric heater is used in a bathroom or other environment, water incident on the second sound hole 10131 on the upper cover 1013 from different angles can be blocked by the upper cover 1012 and flow downwards, and is not easy to enter the interior of the shell 1, causing a short circuit in the electronic components in the electric heater.

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

[0121] By such arrangement, when water is incident on the second sound outlet 10131 on the upper cover 1013 from different angles, it can be blocked by the upper cover 1012 and flow downwards, and is not easy to enter the interior of the shell 1 to cause a short circuit in the electronic components in the electric heater.

[0122] As a convertible implementation, the second sound outlet hole 10131 may also be optionally arranged at one side of the first sound outlet hole 10121 along the horizontal direction.

[0123] In one embodiment, Fig. 9 As shown, there are multiple second sound outlet holes 10131 distributed in an array.

[0124] By such a configuration, it is possible to ensure that the second sound outlet holes 10131 have a larger total area while reducing the size of a single second sound outlet hole 10131, thereby reducing the risk of water ingress at the second sound outlet holes 10131 while ensuring the playback volume of the voice playback device 2.

[0125] It should be noted that in the embodiment of the present application, there is no limitation on the number of the second sound outlet holes 10131 .

[0126] Exemplarily, in an optional embodiment, four rows of second sound outlet holes 10131 are included, and each row of second sound outlet holes 10131 has seven holes.

[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 Fig.10 As shown, the display panel 1015 is disposed on the upper cover 1013. The display panel 1016 and the main board 1017 are disposed under the upper cover 1013. The voice main control module is disposed on the main board 1017, and the voice playback module is connected to the main board 1017 for communication.

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

[0130] By such arrangement, even if a small amount of water flows into the upper cover plate 1012, it can overflow to the lower cover plate 1024 through the first water leakage hole 10122 in sequence, and the water can be promptly discharged to the outside of the whole machine through the second water leakage hole 10241 provided on the lower cover plate 1024. In addition, when a small amount of water flows into the lower cover plate 1024 through the sound pickup hole 1023, the second water leakage hole 10241 can also promptly discharge the water from the water leakage hole to the outside of the housing 1, thereby preventing water from accumulating in the housing 1 and causing short circuit of electrical components such as the tipping switch 8.

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

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

[0133] By such arrangement, when the electric heater falls over, the tipping switch 8 can control the electric heater to stop supplying power, thereby avoiding danger.

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

[0135] By setting a second water leakage hole 10241 and a guide structure 10242 on the lower cover 1024, when water enters the upper cover 1013 through the sound pickup hole 1023, it leaks downward through the first water leakage hole 10122 and falls on the lower cover 1024. The guide structure 10242 guides the water falling on the lower cover 1024 to the second water leakage hole 10241, and flows downward through the second water leakage hole 10241, thereby avoiding water accumulation on the lower cover 1024.

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

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

[0138] like Fig.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 arranged in the bracket body 10141, the support leg 10142 is connected to the bracket body 10141, a first connecting part is provided on the bracket body 10141, and a second connecting part is provided on the upper cover 1012, and the first connecting part can be detachably connected to the second connecting part.

[0139] By such arrangement, the second bracket 1014 can be connected to the upper cover 1012 through the legs 10142, and can be used in a complex installation environment in the upper cover 1012. The first connecting portion and the second connecting portion are preferably but not limited to connectable components, bolt 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 plugged into the limiting groove.

[0141] In one embodiment, the second bracket 1014 is spaced apart from the side wall of the upper cover 1012 in the horizontal direction. By so arranging, an air cavity can be formed between the sound outlet side of the voice playback device 2 and the first sound outlet hole 10121, so as to avoid the misalignment of the first sound outlet hole 10121 and the second sound outlet hole 10131, which affects the sound output effect of the voice playback device 2.

[0142] Therefore, the second bracket 1014 of the embodiment of the present application allows the first sound hole 10121 and the second sound hole 10131 to be staggered to prevent water from flowing into the shell 1 without affecting the sound 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 in the rotating mechanism 4. The first frame assembly 5 and the second frame assembly 6 are respectively arranged on both sides of the rotating mechanism 4 and are rotatably connected to the rotating mechanism 4.

[0145] By setting it up like this, 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 arranged at an angle to adapt to the use environment in the corner.

[0147] When the electric heater is applied to a vertical 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 using, Fig.16 As shown, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate toward each other, thereby realizing the folding of the electric heater and further reducing the space occupied by the electric heater.

[0149] In one embodiment, Fig.15 and Fig.17 As shown, the outer periphery of the rotating mechanism 4 is provided with a first area 401 and a second area 402 , the first frame assembly 5 and the second frame assembly 6 can rotate within the range of the first area 401 , and the voice collection device 3 and the voice playback device 2 are arranged in the second area 402 of the rotating mechanism 4 .

[0150] By such an arrangement, no matter what angle the first frame component 5 and the second frame component 6 are rotated to, the second area 402 will not be blocked. By arranging the voice acquisition device 3 and the voice playback device 2 in 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 collecting the voice commands issued by the user, nor hinder the interactive voice issued by the voice playback device 2.

[0151] In one recent embodiment, Fig.15 As shown, the rotating mechanism 4 includes a first sleeve 403 and a second sleeve 404 .

[0152] The first sleeve 403 and the second sleeve 404 are arranged 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 sleeve 403, and the second frame assembly 6 is connected to the second sleeve 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 being connected to each other by screws.

[0154] In one embodiment, the first frame assembly 5 and the second frame assembly 6 are connected to the first shaft sleeve 403 and the second shaft sleeve 404 respectively through a decorative shell.

[0155] In one embodiment, Fig.18 As shown, the partition structure includes a multi-layer rib 7 arranged between the first cavity 1011 and the second cavity.

[0156] When the sound played by the voice playback device 2 propagates in the first cavity 1011, it will encounter the obstruction of the multi-layer ribs 7, and finally the sound will be absorbed and will not be collected by the voice collection device 3. Since the acoustic impedance of the plastic box and the air differs by 3500 times, as long as the acoustic impedance differs by more than 20 times, it is a total reflection interface; whether the sound wave is transmitted from the air to the plastic, or from the plastic to the air, the sound intensity that can be transmitted is extremely small; therefore, the multi-layer ribs 7 can effectively reflect and absorb the sound played by the voice playback device 2, and then effectively eliminate the influence of the reverberation generated by the sound played by the voice playback device 2 on the voice collection device 3, and eliminate the influence of the sound broadcast by the voice playback device 2 on the voice collection 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 a shaft sleeve.

[0158] In one embodiment, a plurality of convex ribs are formed on the bottom wall of the upper 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 the embodiment of the present invention has a voice recognition function. The user can adjust the electric heater and obtain the adjustment feedback information of the electric heater without going near the electric heater. The operation is convenient and the user experience is good. In addition, the voice played by the voice playback device 2 can be blocked and absorbed by the partition structure when propagating in the first cavity 1011. When the voice is finally transmitted to the vicinity of the voice collection device 3, it will not be collected by the voice collection device 3, avoiding the occurrence of crosstalk or reverberation, which helps to improve the user experience.

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