Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, and particularly relates to an electric heater. BACKGROUND

[0002] The electric heater with the voice control function can be operated according to the instruction without the user approaching the electric heater, and the user's hands can be completely liberated.

[0003] In the related art, the electric heater with the voice control function comprises a shell, a voice main control module, a voice collection device and a voice playing device arranged in the shell, the voice main control module can adjust the electric heater according to the instruction collected by the voice collection device, and generate an interactive instruction according to the instruction collected by the voice collection device, and the interactive instruction is played through the voice playing device, however, the voice played by the voice playing device is easily collected by the voice collection module when propagating in the shell, which causes the howling, and the electric heater repeatedly executes the interactive instruction, which not only affects the user experience, but also may cause the safety hazard. SUMMARY

[0004] Therefore, the utility model provides an electric heater to solve the problem that the electric heater in the related art may cause the howling in the use process, affect the user experience, and even cause the safety hazard.

[0005] The utility model provides an electric heater, which comprises:

[0006] The shell is provided with a separation structure inside, the separation structure can separate a first cavity and a second cavity in the shell, and the first cavity is arranged above the second cavity.

[0007] The voice collection device is arranged in the first cavity.

[0008] The voice playing device is arranged in the second cavity.

[0009] The voice main control module is in communication connection with the voice playing module and the voice collection module.

[0010] The electric heater of the utility model embodiment can prevent the voice played by the voice playing device from being collected by the voice collection device when propagating in the shell, so that the electric heater can not repeatedly execute the voice instruction, and the user experience is improved.

[0011] The electric heater of the embodiment of the present application divides the first cavity and the second cavity in the shell through the separation structure, and the voice collecting device and the voice playing device are arranged in different cavities. The more obstacles encountered by sound in the propagation path, the more sound waves are absorbed, and the smaller the echo is. The longer the propagation path in the propagation path, the more sound waves are consumed and absorbed. Finally, the sound wave is smaller. Therefore, the voice played by the voice playing device can be hindered and absorbed by the separation structure when the voice is propagated in the first cavity. When the voice is finally transmitted to the vicinity of the voice collecting device, the voice collecting device will not be collected, avoiding the occurrence of phenomena such as echo or reverberation, and helping to improve the user experience.

[0012] In an alternative embodiment, the shell comprises a first cavity assembly, the first cavity assembly comprising:

[0013] The mounting bracket is arranged on the side wall of the mounting bracket.

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

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

[0016] Beneficial effect: through such arrangement, the original mounting bracket of the electric heater can be used to form the first mounting groove, and the original upper cover can be used to form the through hole, so that the installation of the voice collecting device is realized without increasing the bracket, thereby saving a bracket and avoiding the increase of the cost of the electric heater caused by the separate mold of the bracket.

[0017] In an alternative embodiment, a plurality of ribs are arranged on the groove wall of the first mounting groove, and the plurality of ribs are in interference fit with the voice collecting device.

[0018] Beneficial effect: through such arrangement, the first mounting groove can completely wrap the voice collecting device, thereby separating the voice collecting device from the sound played by the voice playing device, and further reducing the interference of the voice playing device on the voice collecting device.

[0019] In an alternative embodiment, the voice collecting module is in interference fit with the side wall of the mounting bracket.

[0020] Beneficial effect: through such arrangement, when the electric heater is used in a bathroom environment, water enters from the through hole on the upper cover. Since the voice collecting device is assembled with the side wall of the upper cover with zero gap, most of the water flow can be blocked in the through hole, thereby achieving waterproof of the water flow in all directions of the through hole, and preventing the internal live parts of the electric heater from being immersed in water.

[0021] In an alternative embodiment, the shell further comprises a second cavity assembly, the second cavity assembly comprising:

[0022] a base, a sound outlet hole being formed on one side wall of the base;

[0023] a lower cover plate arranged at the bottom of the base, the lower cover plate being provided with a second mounting groove, the voice playing device being arranged in the second mounting groove and the sound outlet side being arranged towards the sound outlet hole.

[0024] Beneficial effects: through such an arrangement, the operator can install the voice playing device in the second mounting groove of the lower cover plate, and then install the lower cover plate in the base. During use of the electric heater, the voice played by the voice playing device will pass through the sound outlet hole, and a small part of the voice will remain in the shell. However, since the first cavity assembly and the second cavity assembly are separated from each other, the sound wall of the second mounting groove and the separation assembly can hinder the sound during the propagation of the sound from the second cavity assembly to the first cavity assembly, and finally the sound will be absorbed and will not be collected by the voice collecting device.

[0025] In an alternative embodiment, a first water leakage hole is arranged on the bottom wall of the second mounting groove.

[0026] Beneficial effects: through such an arrangement, when the electric heater is used in a water environment such as a bathroom or is subjected to waterproof test, water will enter the shell from various angles of the sound outlet hole. Since the voice playing device is arranged at the rear side of the sound outlet hole in the present embodiment, the flow rate of the water flow can be slowed down, and the water flow entering the shell can be guided to the bottom surface of the lower cover plate. The first water leakage hole on the lower cover plate can guide the water out, thereby avoiding the water from being filled in the lower cover plate and contacting the high-voltage parts on the lower cover plate, which can cause short circuit of the electric heater.

[0027] In an alternative embodiment, the second cavity assembly further comprises:

[0028] a foot stand arranged at the bottom of the lower cover plate, a second water leakage hole being arranged on the foot stand at a position corresponding to the first water leakage hole, a water outlet connector being arranged at the bottom of the lower cover plate, the second water leakage hole being formed in the water outlet connector, and the water outlet connector being inserted into the second water leakage hole.

[0029] Beneficial effects: through such an arrangement, the water in the lower cover plate can be guided by the water outlet connector to be discharged out of the shell through the second water leakage hole, thereby avoiding the water from being accumulated in the shell.

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

[0031] Beneficial effects: By so setting, when a small amount of water enters into the shell through the gap between the voice playing device and the upper cover, the water flow can also be guided to the lower cover plate by the third water leakage hole, and then discharged to the shell outside through the first water leakage hole and the second water leakage hole.

[0032] In an alternative embodiment, a flow guide structure is arranged on the lower cover plate, and the flow guide structure is in communication with the at least one second water leakage hole.

[0033] Beneficial effects: By arranging the second water leakage hole and the flow guide structure on the lower cover plate, when water enters into the upper cover through the through hole, and then leaks downward through the first water leakage hole and falls on the lower cover plate, the flow guide structure guides the water falling on the lower cover plate to the second water leakage hole, and then flows downward through the second water leakage hole, so that the water accumulation on the lower cover plate can be avoided.

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

[0035] The base has a top wall, and the top wall forms part of the separation structure.

[0036] Beneficial effects: By so setting, the bottom wall of the mounting bracket and the top wall of the base can serve as the separation structure, and separate the first cavity and the second cavity from each other. Since the sound impedance of the air in the plastic box differs by 3500 times, as long as the sound impedance difference is 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 playing device, thereby effectively eliminating the influence of the reverberation caused by the sound played by the voice playing device on the voice collecting device, and eliminating the influence of the sound played by the voice playing device on the voice collecting device.

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

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

[0039] A first frame assembly and a second frame assembly are respectively arranged on both sides of the rotating mechanism and are rotationally connected with the rotating mechanism; the first frame assembly and the second frame assembly can rotate within the range of the first area, and the voice collecting device and the voice playing device are arranged in the second area of the rotating mechanism. Beneficial effects: By so setting, during the use of the electric heater, the operator can rotate the first frame assembly and the second frame assembly to change the form of the electric heater, so that the electric heater can adapt to the indoor layout.

[0040] Exemplarily, when the electric heater is used at a corner of a 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 arranged at an angle to adapt to the use environment at the corner of the wall.

[0041] When the electric heater is used at 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 arranged in a straight line.

[0042] When the electric heater is used, the operator can drive the first frame assembly and the second frame assembly to rotate towards each other, so as to realize the folding of the electric heater, thereby reducing the space occupied by the electric heater.

[0043] In addition, since the first frame assembly and the second frame assembly can rotate in the first area, and the voice collecting device and the voice playing device are arranged in the second area, no matter at what angle the first frame assembly and the second frame assembly rotate, the second area will not be blocked, and the voice collecting device and the voice playing device arranged in the second area can ensure that the first frame assembly and the second frame assembly will not hinder the voice collecting device from collecting the voice instruction issued by the user, and will not hinder the voice playing device from playing the interactive voice.

[0044] In an optional embodiment, the separation structure comprises:

[0045] At least two shaft sleeves are arranged between the first cavity and the second cavity and are arranged along the length direction of the rotating mechanism, and the first frame assembly and the second frame assembly are respectively connected with the rotating mechanism through one shaft sleeve.

[0046] Beneficial effects: through the above arrangement, the shaft sleeve can be used to connect the first frame assembly and the second frame assembly with the rotating mechanism, and since the shaft sleeve itself is arranged between the first cavity and the second cavity, the shaft sleeve itself can also serve as a layer of rib to block the sound played by the voice playing device, thereby increasing the number of ribs between the first cavity and the second cavity, and effectively eliminating the influence of the reverberation of the sound played by the voice playing device on the voice collecting device and eliminating the influence of the sound played by the voice playing device on the voice collecting device.

[0088] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0089] The skirting electric heater can be folded and unfolded, meeting different requirements of users. The control mode of the skirting electric heater in the related art is mechanical (adjusting power through a knob or a wave switch); touch key electronic (also needing to walk to the sample machine side to manually touch the key operation); remote control (needing to use a remote controller to manually press the key operation); WIFI control (needing to operate by means of a mobile phone APP); online voice (needing to realize by means of other equipment). Therefore, the control of the skirting electric heater in the related art is not convenient.

[0090] Since the folded skirting heater is small in space, the voice collecting device (microphone) is close to the voice playing device, and there is a howling (that is, the instruction played by the voice playing device is also collected by the voice collecting device); after the howling, the whole electric heater repeatedly executes the voice instruction; when the playing sound of the loudspeaker encounters some obstacles to produce an echo, the echo is collected by the microphone, which also causes the howling; the sound played by the loudspeaker produces a reverberation to affect the microphone; thereby affecting the accuracy of voice recognition.

[0091] Voice reverberation refers to the multiple echo phenomenon produced by the reflection of walls, floors, ceilings and other objects when sound propagates in a room or space. These reflected sounds mix with the direct sound, which can cause the original sound to become unclear, affecting the auditory experience and the accuracy of voice recognition. In audio processing and voice communication technology, it is usually necessary to use a de-reverberation technology to reduce or eliminate these adverse effects to improve the quality and clarity of the sound.

[0092] In addition, a through hole needs to be arranged on the whole machine to realize voice instruction collection by the microphone, and a sound hole needs to be arranged to realize voice broadcast device interaction with the user, and the through hole and the sound hole are prone to water ingress, thereby failing to meet the waterproof requirement of the whole machine.

[0093] The folding skirting line can be folded at 0-180 degrees, and when folded at 0 degrees, the angle formed by the left and right heating assemblies is 0 degrees, at this time, the through hole and the sound hole cannot be blocked, otherwise the offline voice function will be invalid; the through hole collects voice instructions transmitted by air, and the sound hole also transmits voice instructions to the user by air, therefore, the through hole and the sound hole cannot be blocked, and need to be designed towards the direction outside the skirting line heater whole machine, thereby causing smaller space available on the heater.

[0094] When the diameter of the through hole is small, the microphone cannot collect voice instructions; when the diameter of the sound hole is small or the number of the sound holes is small, the broadcast voice for interaction with the user cannot be emitted from the whole machine and greater reverberation is caused; when the diameter of the through hole and the sound hole is large and the number of the through hole and the sound hole is large, the whole machine is not waterproof.

[0095] The embodiments of the present application are described below in combination with Figures 1 to 20 .

[0096] According to the embodiments of the present application, on the one hand, an electric heater is provided, which comprises a shell 1, a voice collection device 2, a voice broadcast device 3 and a voice main control module.

[0097] As shown in Figure 16 and Figure 17 , the shell 1 is provided with a separation structure 103, the separation structure 103 can separate a first cavity 101 and a second cavity 102 in the shell 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 broadcast device 3 is arranged in the second cavity 102. The voice main control module is in communication connection with the voice broadcast module and the voice collection module.

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

[0099] Therefore, the user can adjust the electric heater without going to the vicinity of the electric heater and can obtain the adjustment feedback information of the electric heater, which is convenient to operate and good in user experience.

[0100] On this basis, part of the voice played by the voice broadcast device 3 will be transmitted in the shell 1, and if collected by the voice collection device 2, the electric heater will repeatedly execute the voice instructions, thereby affecting the user experience.

[0101] The electric heater of the embodiment of the present application divides the first cavity 101 and the second cavity 102 in the shell 1 by the partition structure 103, and sets the voice collecting device 2 and the voice playing device 3 in different cavities. The more obstacles encountered by sound in the propagation path, the more sound waves are absorbed, and the smaller the echo is. The longer the propagation path in the propagation path, the more sound waves are consumed and absorbed, and the smaller the sound waves are. Therefore, the voice played by the voice playing device 3 can be hindered and absorbed by the partition structure 103 when the voice is propagated in the first cavity 101, and the voice is not collected by the voice collecting device 2 when the voice is finally transmitted to the vicinity of the voice collecting device 2, avoiding the occurrence of phenomena such as howling or reverberation, and helping to improve the user experience.

[0102] Preferably but not limitedly, the voice collecting device 2 is a microphone. Preferably but not limitedly, the voice playing device 3 is a loudspeaker.

[0103] In one embodiment, as shown in Figures 2 to 4 The shell 1 comprises a first cavity assembly 104.

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

[0105] Preferably but not limitedly, as shown in Figure 5 The mounting bracket 1041 is provided with a first mounting groove 10411 on one side wall. The upper cover 1042 is provided on the mounting bracket 1041, and the upper cover 1042 is provided with a through hole 10421 at a position corresponding to the first mounting groove 10411. The voice collecting device 2 is arranged in the first mounting groove 10411, and the collecting side of the voice collecting device 2 faces the through hole 10421.

[0106] In this way, 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 collecting device 2 is installed without increasing the bracket, thereby saving a bracket and avoiding the increase of the cost of the electric heater caused by the separate mold of the bracket.

[0107] As a convertible embodiment, the first cavity assembly 104 is provided with a first bracket which is detachably connected to the upper cover 1042.

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

[0109] The display panel 1043 is arranged on the upper cover 1042. The display panel 1044 and the main panel 1045 are arranged under the upper cover 1042. The voice master control module is arranged on the main panel 1045, and the voice playing module is in communication connection with the main panel 1045.

[0110] In one embodiment, as shown in Figure 6 and Figure 7 the first mounting groove 10411 is in interference fit with the voice collecting device 2.

[0111] By such arrangement, the first mounting groove 10411 can completely wrap the voice collecting device 2, thereby separating the voice collecting device 2 from the sound played by the voice playing device 3, and further reducing the interference of the voice playing device 3 on the voice collecting device 2.

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

[0113] By such arrangement, when the electric heater is used in the bathroom environment, water enters from the through hole 10421 on the upper cover 1042. Since the voice collecting device 2 is in zero-gap fit with the side wall of the upper cover 1042, most of the water flow can be blocked in the through hole 10421, thereby achieving waterproof of the water flow in all directions of the through hole 10421, ensuring that the diameter of the through hole 10421 can be set larger to avoid that the voice collecting device 2 cannot collect voice instructions while not causing the water immersion of the live parts inside the whole electric heater.

[0114] In addition, since the voice collecting device 2 is designed to be in zero-gap fit with the upper cover 1042, there is no air cavity between the voice collecting device 2 and the upper cover 1042, which makes the voice collecting device 2 unable to collect the sound inside the shell 1, thereby avoiding the interference of the sound emitted by the voice playing device 3 on the voice collecting device 2.

[0115] In one embodiment, as shown in Figure 5 the inner periphery of the first mounting groove 10411 is provided with a plurality of ribs 10413, which can wrap the voice collecting device 2, thereby separating the voice collecting device 2 from the sound played by the voice playing device 3, and further reducing the interference of the voice playing device 3 on the voice collecting device 2.

[0116] In one embodiment, as shown in Figures 9 to 12 the shell 1 further comprises a second cavity assembly 105.

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

[0118] The side wall of the base 1051 is provided with a sound outlet hole 10511. The lower cover plate 1052 is arranged at the bottom of the base 1051, and the lower cover plate 1052 is provided with a second mounting groove 10521, and the voice playing device 3 is arranged in the second mounting groove 10521, and the sound outlet side is arranged towards the sound outlet hole 10511.

[0119] In this way, the operator can install the voice playing device 3 in the second mounting groove 10521 (see Figure 12 and Figure 13 ) of the lower cover plate 1052, and then install the lower cover plate 1052 in the base 1051. During use of the electric heater, the voice played by the voice playing device 3 can pass through the sound outlet hole 10511, and a small part of the voice can remain in the shell 1, but because the first cavity assembly 104 and the second cavity assembly 105 are separated from each other, the sound wall of the second mounting groove 10521 and the partition assembly can hinder the propagation of the sound played by the voice playing device 3 from the second cavity assembly 105 to the first cavity assembly 104, and finally the sound is absorbed and cannot be collected by the voice collecting device 2.

[0120] In an embodiment, the sound outlet hole 10511 is arranged in an array, which can avoid the broadcast voice sound interacting with the user to be trapped in the shell 1, causing reverberation. Because the lower cover plate 1052 and the foot stand 1053 are respectively provided with the first water leakage hole 10522 and the second water leakage hole 10531, the water entering the shell 1 can be guided out through the first water leakage hole 10522 and the second water leakage hole 10531, and the waterproof performance of the whole machine is not affected. Therefore, the electric heater of the embodiment of the present application can avoid causing reverberation while not affecting the waterproof performance of the whole machine.

[0121] Preferably but not limitedly, the sound outlet hole 10511 is arranged in a circular array or a rectangular array. For example, as shown in Figure 14 , the sound outlet hole 10511 is arranged in a circular array, which can be arranged one-to-one with the sound outlet hole of the voice playing device 3, and can further avoid the sound played by the voice playing device 3 remaining in the shell 1.

[0122] In an embodiment, as shown in Figure 11 , the lower cover plate 1052 is provided with a tipping switch 7.

[0123] In this way, when the electric heater tips over, the tipping switch 7 can control the power supply of the electric heater to stop, thereby avoiding causing danger.

[0124] In an embodiment, as shown in Figure 13 and Figure 15 , the bottom wall 1031 of the second mounting groove 10521 is provided with the first water leakage hole 10522.

[0125] By so arranging, when the electric heater is used in a water environment such as a bathroom, or when a waterproof test is performed, water will enter the shell 1 from various angles of the sound outlet hole 10511, and since in the embodiment of the present application, the voice playing device 3 is located at the rear side of the sound outlet hole 10511, the flow rate of the water flow can be slowed down, and the water flow entering the shell 1 can be guided to the bottom surface of the lower cover plate 1052. The first water leakage hole 10522 on the lower cover plate 1052 can guide the water out, thereby avoiding the water from being filled in the lower cover plate 1052, contacting the high-voltage components on the lower cover plate 1052, and causing the electric heater to short circuit.

[0126] In one embodiment, as shown in Figure 13 The second cavity assembly 105 further includes a foot stand 1053. The foot stand 1053 is arranged at the bottom of the lower cover plate 1052. The foot stand 1053 is provided with a second water leakage hole 10531 at a position corresponding to the first water leakage hole 10522. The bottom of the lower cover plate 1052 is provided with a water outlet connector 10523, and the first water leakage hole 10522 is formed in the water outlet connector 10523. The water outlet connector 10523 is inserted into the second water leakage hole 10531.

[0127] By so arranging, the water in the lower cover plate 1052 can be guided by the water outlet connector 10523 to flow out of the shell 1 through the second water leakage hole 10531, thereby avoiding the water from being accumulated in the shell 1.

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

[0129] By so arranging, when a small amount of water enters the shell 1 through the gap between the voice playing device 3 and the upper cover 1042, the water flow can also be guided by the third water leakage hole 10412 to the lower cover plate 1052, and then flow out of the shell 1 through the first water leakage hole 10522 and the second water leakage hole 10531.

[0130] In one embodiment, as shown in Figure 15 The lower cover plate 1052 is provided with a flow guiding structure 10524, and the flow guiding structure 10524 is in communication with at least one second water leakage hole 10531.

[0131] By arranging the second water leakage hole 10531 and the flow guiding structure 10524 on the lower cover plate 1052, when water enters the inside of the upper cover 1042 through the through hole 10421, and then flows down through the first water leakage hole 10522 and falls on the lower cover plate 1052, the flow guiding structure 10524 guides the water falling on the lower cover plate 1052 to the second water leakage hole 10531, and then flows down through the second water leakage hole 10531, thereby avoiding the water from being accumulated on the lower cover plate 1052.

[0132] In one embodiment, the flow guide structure 10524 is a flow guide channel surrounded by flow guide ribs, which can guide water to flow out through the second water leakage hole 10241 and avoid water flow from contacting the electrical element.

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

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

[0135] By so arranging, the bottom wall 1031 of the mounting bracket 1041 and the top wall 1032 of the base 1051 can serve as the partition structure 103 and separate the first cavity 101 and the second cavity 102 from each other. Since the acoustic impedance of air and plastic differs by 3500 times, as long as the acoustic impedance difference is more than 20 times, it is a total reflection interface. No matter whether the sound wave is transmitted from air to plastic or from plastic to 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 playing device 3, thereby effectively eliminating the influence of the reverberation caused by the sound played by the voice playing device 3 on the voice collecting device 2 and eliminating the influence of the sound played by the voice playing device 3 on the voice collecting device 2.

[0136] In one embodiment, as shown in Figure 1 and Figure 19 The electric heater comprises 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 arranged on the two sides of the rotating mechanism 4 and are rotationally connected with the rotating mechanism 4.

[0138] By so arranging, during 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 at a corner of a room, 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 at the corner of the room.

[0140] 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 type.

[0141] When the electric heater is used, the operator can drive the first frame assembly 5 and the second frame assembly 6 to rotate towards each other, so as to realize the folding of the electric heater, thereby reducing the space occupied by the electric heater.

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

[0143] By such arrangement, no matter how much the first frame assembly 5 and the second frame assembly 6 rotate, the second area 402 will not be blocked, and by arranging the voice collecting device 2 and the voice playing device 3 in the second area 402, it can be ensured that the first frame assembly 5 and the second frame assembly 6 will neither hinder the voice collecting device 2 from collecting the voice instructions issued by the user, nor hinder the voice playing device 3 from issuing the interactive voice.

[0144] In one embodiment, the first area 401 and the second area 402 are arranged on the rotating mechanism 4 in a spaced manner along the rotating direction of the first frame assembly 5. Exemplarily, as shown in Figure 1 and Figure 20 , the first area 401 is arranged on the front side of the rotating mechanism 4, and the second area 402 is arranged on the rear side of the rotating mechanism 4.

[0145] In one embodiment, as shown in Figure 16 and Figure 20 , the partition structure 103 further comprises a shaft sleeve 1033. The shaft sleeve 1033 is arranged between the first cavity 101 and the second cavity 102, and there are at least two shaft sleeves 1033 arranged in a spaced manner along the length direction of the rotating mechanism 4, and the first frame assembly 5 and the second frame assembly 6 are respectively connected with the rotating mechanism 4 through one shaft sleeve 1033.

[0146] By so arranging, the shaft 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 can serve as a layer of ribs to block the sound played by the voice playing device 3 due to the fact that the shaft sleeve 1033 is arranged between the first cavity 101 and the second cavity 102, thereby increasing the number of ribs between the first cavity 101 and the second cavity 102, and effectively eliminating the influence of the sound played by the voice playing device 3 on the voice collecting device 2 and the influence of the sound played by the voice playing device 3 on the voice collecting device 2.

[0147] In conclusion, the electric heater with the voice recognition function can be adjusted by the user without walking to the electric heater, and the user can obtain the feedback information of the electric heater, which is convenient to operate and good in user experience. In addition, the voice played by the voice playing device 3 can be hindered and absorbed by the partition structure 103 when the voice is spread in the first cavity 101, and the voice will not be collected by the voice collecting device 2 when the voice is finally transmitted to the vicinity of the voice collecting device 2, so that the occurrence of the phenomena such as the sound leakage or the echo is avoided, which is helpful to improve the user experience.

[0148] Although the embodiments of the present application are described in combination with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope of the present application.
