[0069] 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 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.

[0070] The skirting line electric heater can be folded and unfolded, meeting different requirements of users. The control mode of the skirting line electric heater in the related art is mechanical (power is adjusted through a knob or a wave switch); touch key electronic (it also needs to walk to the sample machine side to manually touch the key operation); remote control (it needs to use a remote controller to manually press the key operation); WIFI control (it needs to use a mobile phone APP operation); online voice (it needs to use other equipment to realize). Therefore, the control of the skirting line electric heater in the related art is not convenient.

[0071] Since the folded skirting line heater is small in space, the voice collection device (microphone) is close to the voice broadcast device, and there is a howling (that is, the instruction broadcasted by the voice broadcast device is also collected by the voice collection device). After the howling, the whole electric heater repeatedly executes the voice instruction. When the broadcast sound of the loudspeaker encounters some obstacles to produce an echo, the echo is collected by the microphone, which also causes howling. The broadcast sound of the loudspeaker produces reverberation, which affects the microphone. Therefore, the accuracy of voice recognition is affected.

[0072] Voice reverberation refers to the multiple echo phenomenon of sound propagation in a room or space due to the reflection of walls, floors, ceilings and other objects. 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.

[0073] In addition, the whole machine needs to be provided with a mounting hole 102 to collect voice instructions by a microphone, and needs to be provided with a sound hole 105 to realize voice broadcast equipment interacting with a user, and the mounting hole 102 and the sound hole 105 are both easy to enter water, thereby failing to meet the waterproof requirement of the whole machine.

[0074] As shown in Figure 13 , the folding skirting line can be folded at 0°-180°, when folded at 0°, the angle formed by the left and right heating assemblies is 0°, at this time, the mounting hole 102 and the sound hole 105 cannot be blocked, otherwise the offline voice function will be invalid; the mounting hole 102 collects voice instructions propagated by air, and the voice instructions broadcast by the sound hole 105 are also propagated to the user by air, therefore, the mounting hole 102 and the sound hole 105 cannot be blocked, and need to be designed towards the direction outside the whole machine of the skirting line warmer, thereby causing that the space that can be selected on the warmer is smaller.

[0075] When the diameter of the mounting hole is small or the number of the mounting hole is small, the microphone cannot collect voice instructions; when the diameter of the sound hole is small or the number of the sound hole is small, the broadcast voice sound interacting with the user is blocked in the whole machine and cannot be output, and greater reverberation is caused; when the diameter of the mounting hole and the sound hole is large or the number of the mounting hole and the sound hole is large, the whole machine is not waterproof.

[0076] The embodiments of the present application are described below in combination with Figures 1 to 13 .

[0077] According to the embodiments of the present application, on the one hand, an electric heater is provided, which comprises a shell 1, a mounting piece 2, a plurality of side walls 4 and electronic devices.

[0078] The shell 1 is provided with a mounting hole 102, a mounting cavity 101 and a drain hole, the mounting hole 102 is arranged at the upper portion of the shell 1, the mounting cavity 101 is in communication with the mounting hole 102, the mounting piece 2 is arranged at the mounting hole 102, and the drain hole is arranged at the bottom of the shell 1. The plurality of side walls 4 are arranged in the shell 1 and can enclose a drain passage 3, one end of the drain passage 3 is in communication with the mounting cavity 101, and the other end is in communication with the drain hole. The electronic devices are arranged in the shell 1 and are spaced apart from the drain passage 3.

[0079] In the use process of the electric heater of the embodiments of the present application, when water enters the mounting hole 102 at the upper portion of the shell 1, the drain passage 3 can guide the water in the mounting cavity 101 out, and the water is discharged through the drain hole at the bottom of the shell 1, thereby avoiding the problem that the water contacts the electronic devices and causes the electronic devices to be short-circuited or corroded, and helping to prolong the service life of the electric heater.

[0080] Preferably, but not limited to, the mounting piece 2 is a microphone.

[0081] In one embodiment, as shown in Figure 3 and Figure 4As shown, the electronic device is arranged below the mounting member 2. The plurality of side walls 4 include a flow guide rib 401 and a partition rib 402.

[0082] The flow guide rib 401 is connected to the bottom wall of the mounting cavity 101 and is used to receive water in the mounting cavity 101. The flow guide rib 401 is inclined downward from top to bottom, away from the electronic device. One end of the partition rib 402 is connected to the flow guide rib 401, and the other end is connected to the bottom wall of the housing 1. The drainage channel 3 and the electronic device are respectively formed on the two sides of the partition rib 402.

[0083] In this way, the flow guide rib 401 can guide the water flow to avoid the electronic device during falling, and the partition rib 402 can separate the electronic device from the drainage channel 3, thereby avoiding the contact between the electronic device and the water.

[0084] In one embodiment, the electronic device includes a heating device 501, which includes a heating terminal 5011 and a heating portion 5012.

[0085] The electric heater further includes a water isolation plate 6.

[0086] The water isolation plate 6 is arranged in the housing 1 and separates the housing 1 into a first cavity 104 and a second cavity 106 arranged in a horizontal direction. The first cavity 104 is arranged on the side of the second cavity 106 close to the mounting cavity 101. The heating device 501 is connected to the water isolation plate 6. The heating terminal 5011 and the mounting cavity 101 are arranged in the first cavity 104. The heating portion 5012 and the water outlet hole are arranged in the second cavity 106. The bottom of the water isolation plate 6 is provided with a flow hole 601.

[0087] In this way, the water flow in the drainage channel 3 can enter the second cavity 106 through the flow hole 601 on the water isolation plate 6 and be discharged through the water outlet hole arranged on the bottom wall of the second cavity 106.

[0088] Thus, the second cavity 106 provided with the water outlet hole is separated from the first cavity 104 by the water isolation plate 6, avoiding the water outlet hole in the first cavity 104 provided with the electronic device such as the heating terminal 5011 which cannot be in contact with water, further reducing the risk of rainwater contacting the electronic device.

[0089] On this basis, as shown in Figure 1 and Figure 2 The water isolation plate 6 can also be used to mount the heating device 501. The water isolation plate 6 has multiple functions, which can reduce the number of parts in the electric heater, make the structure of the electric heater more compact, and help reduce the cost of the electric heater.

[0090] In one embodiment, the electronic device further includes a temperature limiter 502.

[0091] Exemplarily, in an optional embodiment, the temperature limiter 502 is arranged below the flow guide rib 401 and above the heating terminal 5011.

[0092] In an embodiment, the plurality of side walls 4 further comprise a water guide rib 403. The water guide rib 403 is arranged on the bottom wall of the shell 1, connected to the partition rib 402, and extends towards the overflow hole 601.

[0093] In this way, the water guide rib 403 can guide the water from the partition rib 402 towards the overflow hole 601, and then guide the water flow to be discharged through the drain hole, so as to avoid water accumulation in the shell 1, causing bacteria breeding or odor generation.

[0094] In an embodiment, the bottom wall of the mounting cavity 101 is provided with a water inlet 109, which is arranged at one side of the mounting member 2, and the first end of the drain channel 3 is in communication with the water inlet 109.

[0095] In this way, the water on the bottom wall of the mounting cavity 101 can flow into the drain channel 3 through the water inlet 109.

[0096] As a variable implementation, the water inlet 109 can also be arranged on the side wall of the mounting cavity 101 and located at the lower part of the mounting cavity 101.

[0097] In an embodiment, the mounting cavity 101 is provided with an annular mounting bracket, and the mounting member 2 is arranged in the annular mounting bracket.

[0098] In an embodiment, the mounting member 2 is a voice collecting device, the shell 1 is provided with a sound outlet 105 on one side wall, and the electric heater further comprises a voice playing device 7 and a voice control module.

[0099] The voice playing device 7 is arranged in the shell 1 and located at one side of the sound outlet 105. The voice control module is arranged in the shell 1 and in communication connection with the mounting member 2 and the voice playing device 7.

[0100] The voice collecting device can collect voice instructions, and the voice control module can control the adjustment unit to adjust the electric heater according to the collected voice instructions. By arranging the voice playing device 7, the voice control module can issue interactive instructions according to the collected voice instructions and play them through the voice playing device 7. Therefore, the user does not need to walk close to the electric heater to adjust the electric heater and can obtain the adjustment feedback information of the electric heater, which is convenient to operate and good in user experience.

[0101] On this basis, the voice collecting device is arranged at the upper part of the shell 1, which can be closer to the sound source of the user and reduce the interference of environmental noise, thereby improving the accuracy of voice recognition.

[0102] In the embodiment, the voice playing device 7 is arranged on the side wall of the shell 1, and the voice collecting device is arranged on the upper part of the shell 1. Therefore, the distance between the voice playing device 7 and the voice collecting device is far, and the shell 1 can avoid that the voice played by the voice playing device 7 is collected by the voice collecting device, thereby avoiding the occurrence of the echo or the reverberation.

[0103] In one embodiment, the shell 1 is provided with a separation structure, and the separation structure separates the upper cavity assembly 107 and the lower cavity assembly 108 in the shell 1. The upper cavity assembly 107 and the lower cavity assembly 108 are arranged in sequence from top to bottom, and the voice playing device 7 is arranged in the lower cavity assembly 108.

[0104] The voice played by the voice playing device may be partially left in the shell 1, and there is a risk that the voice played by the voice playing device is collected by the voice collecting device, causing the echo or the reverberation.

[0105] The electric heater of the present application separates the upper cavity assembly 107 and the lower cavity assembly 108 in the shell 1 through the separation structure, and arranges the voice collecting device and the voice playing device in different cavities. When the sound propagates in the lower cavity assembly, the sound is blocked by the separation structure, thereby effectively reducing the risk of the occurrence of the echo or the reverberation.

[0106] In one embodiment, the upper cavity assembly 107 is surrounded by the display panel 1071, the upper cover 1072 and the cover plate 1073.

[0107] The lower cavity assembly 108 is surrounded by the lower cover plate 1082 and the base 1081.

[0108] In one embodiment, the electric heater further comprises a base 8 and a heating body 9.

[0109] The voice playing device 7 is arranged on the base 8. The heating body 9 is rotatably connected to the base 8 and can rotate towards the first side of the base 8. The voice playing device 7 is arranged on the second side of the heating body 9.

[0110] In this way, the heating body 9 can rotate relative to the base, thereby changing the shape of the electric heater and adapting to different use environments.

[0111] On this basis, the voice playing device is arranged on the side wall of the base 8 away from the rotation direction of the heating body 9, thereby avoiding that the heating body 9 blocks the voice playing device 7 during the rotation.

[0112] In one embodiment, the upper cavity assembly 107 and the lower cavity assembly 108 are formed on the base. The heater 501 and the temperature controller are arranged in the heating body 9.

[0113] In one embodiment, the heating body 9 is arranged in pairs and arranged on both sides of the base 8.

[0114] In one embodiment, the mounting cavity 101 is arranged in the heating body 9.

[0115] By such arrangement, the distance between the voice playing device 7 and the voice collecting device can be further increased, and the risk of the voice played by the voice playing device 7 being collected by the voice collecting device can be reduced.

[0116] As a convertible embodiment, in an embodiment not shown in the drawings, the mounting cavity 101 is arranged in the first cavity 104 assembly.

[0117] In one embodiment, the mounting hole 102 is arranged on the top wall of the shell 1, and the mounting member 2 is arranged at the corresponding position of the mounting hole 102 and is in interference fit with the top wall of the shell 1.

[0118] By such arrangement, when the electric heater is used in a bathroom or the like, if water falls on the top wall of the shell 1, the water can be blocked in the mounting hole 102 due to the interference fit between the mounting member 2 and the top wall of the shell 1, and cannot flow into the shell 1. Even if a small amount of water seeps into the shell 1, it can be discharged through the drain passage 3 and cannot be accumulated in the shell 1.

[0119] Since the waterproof test is a 360° dead angle test, the above design can achieve waterproof in all directions of the mounting hole 102, and the electronic devices will not be immersed in water.

[0120] In addition, arranging the mounting hole 102 on the top wall of the shell 1 can also avoid the problems of poor sound collection and inaccurate voice recognition caused by the proximity of the electric heater to the cavity wall.

[0121] As a convertible embodiment, in an embodiment not shown in the drawings, the mounting hole 102 is arranged on the side wall of the shell 1 and is located at the upper portion of the shell 1.

[0122] In summary, the electric heater of the embodiments of the present application can ensure accurate recognition of the voice function while meeting the waterproof requirements of the heater, and the electric heater of the present application can meet the IPX4 waterproof level standard.

[0123] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the present application.
