Description

Technical Field

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

[0002] When using an electric heater with voice control function, the user only needs to speak out the instructions, and the product will act according to the instructions. The user does not need to approach the electric heater or use other mobile terminals. Therefore, it can completely free the user's hands and the operation is simple and convenient.

[0003] In the related art, an electric heater with a voice control function includes a shell, and a voice main control module, a voice acquisition device and a voice playback device arranged in the shell. The voice main control module can adjust the electric heater according to the instructions collected by the voice acquisition device, and generate interactive instructions according to the instructions collected by the voice acquisition device, and play the interactive instructions through the voice playback device. However, the voice played by the voice playback device is easily collected by the voice acquisition module when propagating in the shell, causing crosstalk, causing the electric heater to repeatedly execute interactive instructions, which not only affects the user experience, but also may cause safety hazards. Summary of the invention

[0004] In view of this, the present invention provides an electric heater to solve the problem that electric heaters in the related art may have crosstalk during use, which affects the user experience and even causes safety hazards.

[0005] The present invention provides an electric heater, comprising:

[0006] 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;

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

[0008] A voice playback device is disposed in the second cavity;

[0009] The voice master control module is connected to the voice playback module and the voice collection module for communication.

[0010] Beneficial effect: During use of the electric heater of the embodiment of the present invention, 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 the voice instructions, thereby affecting the user experience.

[0011] 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.

[0012] In an optional embodiment, the housing includes a first cavity assembly, and the first cavity assembly includes:

[0013] The mounting bracket is used for mounting the voice collection device.

[0014] In an optional embodiment, a first mounting groove is provided on a side wall of one side of the mounting bracket, and the first cavity assembly further includes:

[0015] The upper cover is arranged on the mounting bracket, a through hole is arranged at a position of the upper cover corresponding to the first mounting groove, the voice collection device is arranged in the first mounting groove, and the collection side of the voice collection device faces the through hole.

[0016] Beneficial effect: Through such an arrangement, the original mounting bracket of the electric heater can be used to form a first mounting groove, and the original upper cover can be used to form a through hole, so that the voice collection device can be installed without adding a bracket, thereby saving a bracket and avoiding the increase in the cost of the electric heater caused by opening a separate mold for the bracket.

[0017] In an optional embodiment, a plurality of ribs are provided on the groove wall of the first installation groove, and the plurality of ribs are interference fit with the voice collection device.

[0018] Beneficial effect: Through such an arrangement, the first installation groove can completely wrap the voice collection device, thereby separating the sound played by the voice collection device from the sound played by the voice playback device, thereby reducing the interference of the voice playback device on the voice collection device.

[0019] In an optional implementation, the voice collection module is interference fit with a side wall of the mounting bracket.

[0020] Beneficial effect: Through such an arrangement, when the electric heater is used in a bathroom environment, water enters from the through hole on the upper cover. Since the voice collection device and the side wall of the upper cover are assembled with zero clearance, most of the water flow can be blocked in the through hole, thereby waterproofing the water flow in all directions of the through hole without causing the internal live parts of the electric heater to be soaked in water.

[0021] In an optional embodiment, the housing further includes a second cavity assembly, and the second cavity assembly includes:

[0022] A base, wherein a sound outlet is formed on a side wall of the base;

[0023] The lower cover plate is arranged at the bottom of the base, and a second installation groove is formed on the lower cover plate. The voice playing device is arranged in the second installation groove, and the sound output side is arranged toward the sound output hole.

[0024] Beneficial effect: Through such a setting, the operator can install the voice playback device in the second installation groove of the lower cover, and then install the lower cover in the base. During the use of the electric heater, the voice played by the voice playback device will come out from the sound outlet, and at the same time, a small part of the voice will remain in the shell, but because the first cavity component and the second cavity component are separated from each other, the groove wall and the partition component of the second installation groove can block the sound during the transmission of the sound played by the voice playback device from the second cavity component to the first cavity component, and finally the sound will be absorbed and will not be collected by the voice collection device.

[0025] In an optional embodiment, a first water leakage hole is provided on the bottom wall of the second installation groove.

[0026] Beneficial effect: With such a configuration, when the electric heater is used in a water environment such as a bathroom, or when a waterproof test is performed, water will be injected into the housing from various angles of the sound outlet. Since the voice playback device is located at the rear side of the sound outlet in the embodiment of the present application, the flow rate of the water flow can be slowed down, so that the water flow entering the housing can be guided to the bottom surface of the lower cover. The first water leakage hole on the lower cover can guide the water out, thereby preventing the water from accumulating in the lower cover and contacting the strong electrical parts on the lower cover, causing the electric heater to short-circuit.

[0027] In an optional embodiment, the second cavity assembly further includes:

[0028] The tripod is arranged at the bottom of the lower cover plate, a second leakage hole is arranged at a position on the tripod corresponding to the first leakage hole, a water outlet joint is arranged at the bottom of the lower cover plate, the second leakage hole is formed in the water outlet joint, and the water outlet joint is inserted in the second leakage hole.

[0029] Beneficial effect: Through such an arrangement, the water in the lower cover plate can be discharged to the outside of the shell through the second water leakage hole under the guidance of the water outlet joint, thereby avoiding water accumulation in the shell.

[0030] In an optional embodiment, the mounting bracket has a bottom wall, and a third water leakage hole is provided on the bottom wall.

[0031] Beneficial effect: Through such an arrangement, when a small amount of water enters the shell through the gap between the voice playback device and the upper cover, the water flow can also be guided to the lower cover plate by the third leakage hole, and discharged to the outside of the shell through the first leakage hole and the second leakage hole in turn.

[0032] 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.

[0033] 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 through 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 the water flows downward through the second water leakage hole, thereby avoiding water accumulation on the lower cover plate.

[0034] In an optional embodiment, the mounting bracket has a bottom wall, and the bottom wall of the mounting bracket forms a part of the partition structure; and / or,

[0035] The base has a top wall which forms part of the partition structure.

[0036] Beneficial effect: Through such an arrangement, the bottom wall of the mounting bracket and the top wall of the base can serve as a partition structure and separate the first cavity and the second cavity from each other. Since the acoustic impedance of the air in the plastic box differs by 3500 times, as long as the acoustic impedance differs by more than 20 times, it is a total reflection interface; no matter 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 bottom wall of the mounting bracket and the top wall of the base can effectively reflect and absorb the sound played by the voice playback device, thereby effectively eliminating the influence of the reverberation generated by the sound played by the voice playback device on the voice collection device, and eliminating the influence of the sound broadcast by the voice playback device on the voice collection device.

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

[0038] A rotating mechanism, wherein a first cavity and a second cavity are formed in the rotating mechanism, and a first area and a second area are provided on the periphery of the rotating mechanism;

[0039] 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; 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. 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Furthermore, since the first frame assembly and the second frame assembly can rotate in the first area, and the voice collection device and the voice playback device are arranged in the second area, no matter what angle the first frame assembly and the second frame assembly are rotated to, the second area will not be blocked. By arranging the voice collection device and the voice playback device in the second area, it can be ensured that the first frame assembly and the second frame assembly 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.

[0044] In an optional embodiment, the partition structure includes:

[0045] At least two shaft sleeves are arranged between the first cavity and the second cavity and are spaced apart along the length direction of the rotating mechanism. The first frame assembly and the second frame assembly are respectively rotatably connected to the rotating mechanism through a shaft sleeve.

[0046] Beneficial effect: Through such a configuration, the sleeve can be used to rotatably connect the first frame assembly and the second frame assembly with the rotating mechanism, and because the sleeve itself is arranged between the first cavity and the second cavity, the sleeve itself can also serve as a layer of ribs to block the sound played by the voice playback device, thereby increasing the number of ribs between the first cavity and the second cavity, and then effectively eliminating the influence of the reverberation generated by the sound played by the voice playback device on the voice collection device, and eliminating the influence of the sound broadcast by the voice playback device on the crosstalk of the voice collection device.

[0088] 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.

[0089] 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.

[0090] Since the space of the folding skirting board heater is small and the distance between the voice collection device (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); the crosstalk will cause the entire electric heater to repeatedly execute 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.

[0091] 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.

[0092] In addition, a through hole is needed on the whole machine to enable the microphone to collect voice commands, and a sound outlet is needed to enable the voice broadcast device to interact with the user. However, both the through hole and the sound outlet are easy to get water in, causing the whole machine to fail to meet the waterproof requirements.

[0093] The folding 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 through hole and the sound hole cannot be blocked, otherwise the offline voice function will fail. The through hole collects voice commands transmitted through the air, and the voice commands broadcast by the sound hole are also transmitted to the user through the air. Therefore, the through hole and the sound hole cannot be blocked and need to be designed toward the outside of the skirting board heater. As a result, there is less room for choice on the heater.

[0094] When the diameter of the through hole is small, the microphone will not be able to collect voice commands; when the diameter of the sound hole is small or the number is small, the broadcast voice sound for interacting with the user will be trapped inside the whole machine and cause greater reverberation; and when the diameter of the through hole and the sound hole are large and the number is large, the whole machine will not be waterproof.

[0095] Combine the following Figures 1 to 20 , describing an embodiment of the present invention.

[0096] According to an embodiment of the present invention, on the one hand, an electric heater is provided, including a housing 1, a voice collection device 2, a voice playback device 3 and a voice main control module.

[0097] Among them, Fig.16 and Fig.17 As shown, a partition structure 103 is provided in the housing 1, and the partition structure 103 can separate a first cavity 101 and a second cavity 102 in the housing 1, and the first cavity 101 is arranged above the second cavity 102. The voice collection device 2 is arranged in the first cavity 101. The voice playback device 3 is arranged in the second cavity 102. The voice main control module is communicatively connected with the voice playback module and the voice collection module.

[0098] The electric heater of the present invention is provided with a voice main control module, a voice acquisition device 2 and a voice playback device 3. The voice main control module can adjust the electric heater according to the instructions collected by the voice acquisition device 2, and generate interactive instructions according to the instructions collected by the voice acquisition device 2, and play the interactive instructions through the voice playback device 3.

[0099] 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.

[0100] On this basis, part of the voice played by the voice playback device 3 will be transmitted inside the shell 1. If it is collected by the voice collection device 2, it will cause the electric heater to repeatedly execute voice commands, thereby affecting the user experience.

[0101] The electric heater of the embodiment of the present application is divided into a first cavity 101 and a second cavity 102 by a partition structure 103 in the shell 1, and the voice collection device 2 and the voice playback device 3 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 3 can be hindered and absorbed by the partition structure 103 when propagating in the first cavity 101. When the voice is finally transmitted to the vicinity of the voice collection device 2, it will not be collected by the voice collection device 2, thereby avoiding the occurrence of phenomena such as crosstalk or reverberation, which helps to improve the user experience.

[0102] The voice collection device 2 is preferably, but not limited to, a microphone. The voice playback device 3 is preferably, but not limited to, a speaker.

[0103] In one embodiment, Figures 2 to 4 As shown, the housing 1 includes a first cavity component 104 .

[0104] The first cavity assembly 104 includes a mounting bracket 1041 and an upper cover 1042 .

[0105] Among them, Figure 5 As shown, a first mounting groove 10411 is provided on one side wall of the mounting bracket 1041. An upper cover 1042 is provided on the mounting bracket 1041, and a through hole 10421 is provided at a position of the upper cover 1042 corresponding to the first mounting groove 10411. The voice collection device 2 is provided in the first mounting groove 10411, and the collection side of the voice collection device 2 faces the through hole 10421.

[0106] Through such an arrangement, the original mounting bracket 1041 of the electric heater can be used to form the first mounting groove 10411, and the original upper cover 1042 can be used to form the through hole 10421, so that the voice collection device 2 can be installed without adding a bracket, thereby saving a bracket and avoiding the increase in the cost of the electric heater caused by opening a separate mold for the bracket.

[0107] As a convertible implementation, a first bracket is provided in the first cavity assembly 104 , and the first bracket is detachably connected to the upper cover 1042 .

[0108] In one embodiment, the first cavity assembly 104 further includes a display panel 1043 , a display board 1044 and a main board 1045 .

[0109] The display panel 1043 is disposed on the upper cover 1042. The display panel 1044 and the main board 1045 are disposed under the upper cover 1042. The voice main control module is disposed on the main board 1045, and the voice playback module is connected to the main board 1045 for communication.

[0110] In one embodiment, Figure 6 and Figure 7 As shown, the groove wall of the first installation groove 10411 is interference fit with the voice collection device 2.

[0111] By such arrangement, the first installation groove 10411 can completely wrap up the voice collection device 2, thereby separating the voice collection device 2 from the sound played by the voice playback device 3, thereby reducing the interference of the voice playback device 3 on the voice collection device 2.

[0112] In one embodiment, the voice collection device 2 is interference fit with the side wall of the upper cover 1042 .

[0113] With such an arrangement, when the electric heater is used in a bathroom environment, water enters from the through hole 10421 on the upper cover 1042. Since the voice acquisition device 2 and the side wall of the upper cover 1042 are assembled with zero clearance, most of the water flow can be blocked in the through hole 10421, thereby waterproofing the water flow in all directions of the through hole 10421, while ensuring that the diameter of the through hole 10421 can be set larger to avoid the voice acquisition device 2 being unable to collect voice commands while preventing the internal live parts of the electric heater from being soaked in water.

[0114] Furthermore, since the voice collection device 2 and the upper cover 1042 are designed to be matched with zero clearance, there is no air cavity between the voice collection device 2 and the upper cover 1042, which makes it impossible for the voice collection device 2 to collect the sound inside the shell 1, thereby avoiding the sound emitted by the voice playback device 3 from interfering with the voice collection device 2.

[0115] In one embodiment, Figure 5 As shown, a plurality of ribs 10413 are provided on the inner circumference of the first mounting groove 10411, and the plurality of ribs 10413 can wrap the voice collection device 2, thereby separating the voice collection device 2 from the sound played by the voice playback device 3, thereby reducing the interference of the voice playback device 3 on the voice collection device 2.

[0116] In one embodiment, Figures 9 to 12 As shown, the housing 1 further includes a second cavity assembly 105 .

[0117] The second cavity assembly 105 includes a base 1051 and a lower cover plate 1052 .

[0118] A sound outlet hole 10511 is formed on one side wall of the base 1051. A lower cover plate 1052 is disposed at the bottom of the base 1051. A second mounting groove 10521 is formed on the lower cover plate 1052. The voice playback device 3 is disposed in the second mounting groove 10521, and the sound outlet side is disposed toward the sound outlet hole 10511.

[0119] By so configuring, the operator can install the voice playback device 3 in the second installation slot 10521 (see FIG. Fig.12 and Fig.13 ), and then install the lower cover 1052 in the base 1051. During the use of the electric heater, the voice played by the voice playback device 3 will come out from the sound outlet 10511, and at the same time, a small part of the voice will remain in the shell 1, but because the first cavity component 104 and the second cavity component 105 are separated from each other, the groove wall and the partition component of the second installation groove 10521 can block the sound during the process of the sound played by the voice playback device 3 propagating from the second cavity component 105 to the first cavity component 104, and finally the sound will be absorbed and will not be collected by the voice collection device 2.

[0120] In one embodiment, the sound outlet holes 10511 are distributed in an array, which can prevent the broadcast voice sound interacting with the user from being trapped in the housing 1 and causing reverberation. Since the first water leakage hole 10522 and the second water leakage hole 10531 are respectively provided on the lower cover plate 1052 and the tripod 1053, the water entering the housing 1 can be discharged through the first water leakage hole 10522 and the second water leakage hole 10531, and will not affect the waterproof performance of the whole machine. Therefore, the electric heater of the embodiment of the present application can avoid causing reverberation without affecting the waterproof performance of the whole machine.

[0121] The sound outlet holes 10511 are preferably, but not limited to, distributed in a circular array or a rectangular array. Fig.14 As shown, the sound outlet holes 10511 are distributed in a circular array and can be set one-to-one with the sound outlet holes of the voice playback device 3, which can further prevent the sound played by the voice playback device 3 from remaining in the shell 1.

[0122] In one embodiment, Fig.11 As shown, a dump switch 7 is provided on the lower cover plate 1052 .

[0123] By such arrangement, when the electric heater falls over, the tipping switch 7 can control the electric heater to stop supplying power, thereby avoiding danger.

[0124] In one embodiment, Fig.13 and Fig.15 As shown, a first water leakage hole 10522 is provided on the bottom wall 1031 of the second installation groove 10521 .

[0125] By such arrangement, when the electric heater is used in a water environment such as a bathroom, or when a waterproof test is performed, water will be injected into the housing 1 from various angles of the sound outlet 10511. Since the voice playback device 3 is located at the rear side of the sound outlet 10511 in the embodiment of the present application, the flow rate of the water flow can be slowed down, so that the water flow entering the housing 1 can be guided to the bottom surface of the lower cover 1052. The first water leakage hole 10522 on the lower cover 1052 can guide the water out, thereby preventing the water from accumulating in the lower cover 1052 and contacting the strong electrical parts on the lower cover 1052, causing the electric heater to short-circuit.

[0126] In one embodiment, Fig.13 As shown, the second cavity assembly 105 further includes a stand 1053. The stand 1053 is disposed at the bottom of the lower cover plate 1052. A second water leakage hole 10531 is disposed at a position corresponding to the first water leakage hole 10522 on the stand 1053, a water outlet joint 10523 is disposed at the bottom of the lower cover plate 1052, the first water leakage hole 10522 is formed in the water outlet joint 10523, and the water outlet joint 10523 is inserted in the second water leakage hole 10531.

[0127] By such arrangement, the water in the lower cover plate 1052 can be discharged to the outside of the housing 1 through the second water leakage hole 10531 under the guidance of the water outlet joint 10523, thereby preventing water from accumulating in the housing 1.

[0128] In one embodiment, Figure 8 As shown, the mounting bracket 1041 has a bottom wall 1031 , and a third water leakage hole 10412 is provided on the bottom wall 1031 .

[0129] Through such an arrangement, when a small amount of water enters the shell 1 through the gap between the voice playback device 3 and the upper cover 1042, the water flow can also be guided to the lower cover 1052 by the third leakage hole 10412, and discharged to the outside of the shell 1 through the first leakage hole 10522 and the second leakage hole 10531 in turn.

[0130] In one embodiment, Fig.15 As shown, a flow guiding structure 10524 is provided on the lower cover plate 1052 , and the flow guiding structure 10524 is connected to at least one second water leakage hole 10531 .

[0131] By setting the second water leakage hole 10531 and the guide structure 10524 on the lower cover plate 1052, when water enters the upper cover 1042 through the through hole 10421, it leaks downwards through the first water leakage hole 10522 and falls on the lower cover plate 1052, the guide structure 10524 guides the water falling on the lower cover plate 1052 to the second water leakage hole 10531, and flows downwards through the second water leakage hole 10531, thereby avoiding water accumulation on the lower cover plate 1052.

[0132] In one embodiment, the guide structure 10524 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.

[0133] In one embodiment, Fig.16 As shown, the mounting bracket 1041 has a bottom wall 1031 , and the bottom wall 1031 of the mounting bracket 1041 forms a part of the partition structure 103 .

[0134] The base 1051 has a top wall 1032 , which forms a part of the partition structure 103 .

[0135] By such an arrangement, the bottom wall 1031 of the mounting bracket 1041 and the top wall 1032 of the base 1051 can serve as a partition structure 103, and separate the first cavity 101 and the second cavity 102 from each other. Since the acoustic impedance of the air in the plastic box differs by 3500 times, as long as the acoustic impedance differs by more than 20 times, it is a total reflection interface; no matter 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 bottom wall 1031 of the mounting bracket 1041 and the top wall 1032 of the base 1051 can effectively reflect and absorb the sound played by the voice playback device 3, thereby effectively eliminating the influence of the reverberation generated by the sound played by the voice playback device 3 on the voice collection device 2, and eliminating the influence of the sound broadcast by the voice playback device 3 on the voice collection device 2.

[0136] In one embodiment, Figure 1 and Fig.19 As shown, the electric heater includes a rotating mechanism 4 , a first frame assembly 5 and a second frame assembly 6 .

[0137] The first cavity 101 and the second cavity 102 are formed in 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.

[0138] By such arrangement, 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.

[0139] 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.

[0140] 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.

[0141] When the electric heater is finished being used, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate toward each other, thereby folding the electric heater and reducing the space occupied by the electric heater.

[0142] In one embodiment, Figure 1 and Fig. 20 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 2 and the voice playback device 3 are arranged in the second area 402 of the rotating mechanism 4 .

[0143] 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 2 and the voice playback device 3 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 2 from collecting the voice commands issued by the user, nor hinder the interactive voice issued by the voice playback device 3.

[0144] In one embodiment, the first area 401 and the second area 402 are arranged on the rotating mechanism 4 at intervals along the rotation direction of the first frame assembly 5. For example, Figure 1 and Fig. 20 As shown, the first area 401 is arranged at the front side of the rotating mechanism 4 , and the second area 402 is arranged at the rear side of the rotating mechanism 4 .

[0145] In one embodiment, Fig.16 and Fig. 20 As shown, the partition structure 103 further includes a sleeve 1033. The sleeve 1033 is disposed between the first cavity 101 and the second cavity 102. There are at least two sleeves 1033, which are spaced apart along the length direction of the rotating mechanism 4. The first frame assembly 5 and the second frame assembly 6 are rotatably connected to the rotating mechanism 4 through a sleeve 1033 respectively.

[0146] By such a configuration, the sleeve 1033 can not only be used to rotatably connect the first frame assembly 5 and the second frame assembly 6 with the rotating mechanism 4, but also because the sleeve 1033 itself is arranged between the first cavity 101 and the second cavity 102, the sleeve 1033 itself can also serve as a layer of ribs to block the sound played by the voice playback device 3, thereby increasing the number of ribs between the first cavity 101 and the second cavity 102, and then effectively eliminating the influence of the reverberation generated by the sound played by the voice playback device 3 on the voice collection device 2, and eliminating the influence of the sound broadcast by the voice playback device 3 on the crosstalk of the voice collection device 2.

[0147] 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 3 can be blocked and absorbed by the partition structure 103 when propagating in the first cavity 101. When the voice is finally transmitted to the vicinity of the voice collection device 2, it will not be collected by the voice collection device 2, avoiding the occurrence of crosstalk or reverberation, which helps to improve the user experience.

[0148] 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.
