Description

Technical Field

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

[0002] Taking heaters as an example, electric heaters with voice recognition functions can well balance intelligence and convenient operability, and are therefore very popular among consumers. Especially in environments such as bathrooms, heaters with voice recognition functions greatly facilitate user use and make the operation of the heater more convenient.

[0003] However, installing a voice collection device requires drilling a hole in the heater shell, which makes it easy for water to flow into the heater shell when the heater is used in a water environment such as a bathroom, and come into contact with the electronic components in the heater, causing a short circuit or corrosion of the electronic components. Summary of the invention

[0004] In view of this, the present invention provides an electric heater to solve the problem in the related art that water easily flows into the interior of electronic devices during use of the electric heater, causing short circuit or corrosion of the electronic devices.

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

[0006] The shell is provided with a mounting hole, a mounting cavity, and a drainage hole. The mounting hole is provided at the upper part of the shell, the mounting cavity is connected with the mounting hole, a mounting piece is provided at the mounting hole, and the drainage hole is provided at the bottom of the shell;

[0007] A plurality of side walls are arranged in the housing and can enclose a drainage channel, one end of the drainage channel is connected to the installation cavity, and the other end is connected to the drainage hole;

[0008] The electronic device is arranged in the shell and spaced apart from the drainage channel.

[0009] Beneficial effect: During use of the electric heater of the embodiment of the present invention, when water enters the mounting hole on the upper part of the shell, the drainage channel can drain the water in the mounting cavity and discharge it through the drainage hole at the bottom of the shell, thereby avoiding water from contacting electronic components and causing short circuits or corrosion of electronic components, thereby helping to extend the service life of the electric heater.

[0010] In an optional embodiment, the electronic device is arranged below the mounting member, and the plurality of side walls include:

[0011] A guide rib is connected to the bottom wall of the installation cavity and is used to receive water in the installation cavity. From top to bottom, the guide rib is inclined in a direction away from the electronic device.

[0012] The partition rib has one end connected to the guide rib and the other end connected to the bottom wall of the shell. The drainage channel and the electronic device are respectively formed on both sides of the partition rib.

[0013] Beneficial effect: Through such an arrangement, the guide ribs can guide the water flow to avoid the electronic components during the falling process, and the separation ribs can separate the electronic components from the drainage channel, thereby preventing the electronic components from contacting with water.

[0014] In an optional embodiment, the electronic device includes a heater, and the heater includes a heating terminal and a heating portion;

[0015] The heater also includes:

[0016] A water-blocking plate is arranged in the shell, and separates a first cavity and a second cavity arranged in a horizontal direction. The first cavity is arranged on the side of the second cavity close to the installation cavity. The heater is connected to the water-blocking plate, the heating terminal and the installation cavity are arranged in the first cavity, the heating part and the water outlet are arranged in the second cavity, and a flow hole is arranged at the bottom of the water-blocking plate.

[0017] Beneficial effect: Through such an arrangement, the water flow in the drainage channel can enter the second cavity through the flow holes on the water-blocking plate, and be discharged through the water outlet holes arranged on the bottom wall of the second cavity.

[0018] Thus, the second cavity with drainage holes is separated from the first cavity by the baffle plate, thereby avoiding the need to open drainage holes in the first cavity with electronic devices such as heating terminals that cannot come into contact with water, thereby further reducing the risk of electronic devices coming into contact with rainwater.

[0019] On this basis, the baffle can also be used to install the heater. The baffle has various functions and can reduce the number of parts in the electric heater, making the structure of the electric heater more compact, which helps to reduce the cost of the equipment.

[0020] In an optional embodiment, the plurality of side walls further include:

[0021] The water guide rib is arranged on the bottom wall of the shell, connected to the separation rib, and extends toward the flow hole.

[0022] Beneficial effect: Through such an arrangement, the water guide ribs can guide the water from the dividing ribs toward the flow holes, and then guide the water flow to be discharged through the drainage holes, so as to avoid water accumulating in the shell, causing bacteria to grow or produce odors.

[0023] In an optional embodiment, a water inlet is provided on the bottom wall of the installation cavity, the water inlet is arranged on one side of the installation component, and the first end of the drainage channel is connected to the water inlet.

[0024] Beneficial effect: Through such an arrangement, water on the bottom wall of the installation cavity can flow into the drainage channel through the water inlet.

[0025] In an optional embodiment, the mounting piece is a voice collection device, a sound outlet is provided on one side wall of the housing, and the electric heater further comprises:

[0026] The voice playing device is arranged in the housing and is located on one side of the sound outlet;

[0027] The voice control module is arranged in the shell and is communicatively connected with the mounting piece and the voice playing device.

[0028] Beneficial effects: The voice playing device is arranged in the shell and is located at one side of the sound outlet. The voice control module is arranged in the shell and is connected to the mounting part and the voice playing device in communication.

[0029] The voice collection device can collect voice commands, and the voice control module can control the adjustment unit to adjust the heater according to the collected voice commands. By setting a voice playback device, the voice control module can issue interactive commands according to the collected voice commands and play them out through the voice playback device. Therefore, the user can adjust the electric heater without going near the electric heater and can get the adjustment feedback information of the electric heater, which is convenient to operate and has a good user experience.

[0030] On this basis, the voice collection device is arranged at the upper part of the shell, which can be closer to the user's voice source and reduce the interference of environmental noise, thereby improving the accuracy of voice recognition.

[0031] The voice playing device is arranged on the side wall of the shell, and the mounting part is arranged on the upper part of the shell. Therefore, the distance between the voice playing device and the mounting part is relatively far. The shell prevents the voice played by the voice playing device from being collected by the mounting part, thereby avoiding crosstalk or reverberation.

[0032] In an optional embodiment, the shell includes an upper cavity assembly and a lower cavity assembly arranged in sequence along the vertical direction, the upper cavity assembly and the lower cavity assembly are arranged in sequence from top to bottom, and the voice playback device is arranged in the lower cavity assembly.

[0033] Beneficial effect: Part of the voice emitted by the voice broadcast device will remain in the shell, and there is a risk that the voice emitted by the voice broadcast device will be collected by the installation component, causing crosstalk or reverberation.

[0034] The electric heater of the present application is separated into an upper cavity component and a lower cavity component in the shell by a partition structure, and the mounting parts and the voice broadcast device are arranged in different cavities. When the sound propagates in the lower cavity component, it will be blocked by the partition structure, which effectively reduces the risk of crosstalk or reverberation.

[0035] In an optional embodiment, a main board is provided in the upper cavity assembly, and the main board is provided with a voice control module.

[0036] In an optional embodiment, the electric heater further comprises:

[0037] A base, on which the voice playing device is arranged;

[0038] The heating body is rotatably connected to the base and can rotate toward a first side of the base. The voice playing device is arranged on a second side of the heating body.

[0039] Beneficial effect: Through such an arrangement, the heating body can rotate relative to the base, thereby changing the shape of the electric heater to adapt to different usage environments.

[0040] On this basis, the voice player is arranged on a side wall of the base away from the rotation direction of the heating body, which can avoid blocking the voice player during the rotation of the heating body.

[0041] In an optional embodiment, the installation cavity is arranged in the heating body.

[0042] Beneficial effect: Through such an arrangement, the distance between the voice playback device and the installation component can be further increased, thereby reducing the risk of the voice played by the voice playback device being collected by the installation component.

[0043] In an optional embodiment, the mounting hole is provided on the top wall of the shell, the mounting piece is provided at a corresponding position of the mounting hole, and is interference fit with the top wall of the shell.

[0044] Beneficial effect: With such a configuration, when the electric heater is used in a bathroom or other environment, when water falls onto the top wall of the shell, the water can be blocked in the mounting hole due to the interference fit between the mounting piece and the top wall of the shell, and will not flow into the shell. Even if a small amount of water penetrates into the shell, it can be discharged through the drainage channel and will not accumulate in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] 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.

[0070] 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.

[0071] 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 command is collected by the voice collection device again); the crosstalk will cause the electric heater to repeatedly execute the voice command; 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.

[0072] 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.

[0073] In addition, the whole machine needs to be provided with a mounting hole 102 to enable the microphone to collect voice commands, and a sound outlet hole 105 is required to enable the voice broadcast device to interact with the user. However, both the mounting hole 102 and the sound outlet hole 105 are prone to water ingress, causing the whole machine to fail to meet the waterproof requirements.

[0074] like Fig.13 As shown, the foldable skirting board can be folded at 0° to 180°. When folded at 0°, the angle formed by the left and right heating components is 0°. At this time, the mounting hole 102 and the sound outlet hole 105 cannot be blocked, otherwise the offline voice function will fail. The mounting hole 102 collects voice commands transmitted through the air, and the voice commands broadcast by the sound outlet hole 105 are also transmitted to the user through the air. Therefore, the mounting hole 102 and the sound outlet hole 105 cannot be blocked and need to be designed toward the outside of the skirting board heater. As a result, there is less room for selection on the heater.

[0075] When the diameter of the mounting holes is small or the number is small, the microphone will not be able to collect voice commands; when the diameter of the sound holes is small or the number is small, the broadcast voice sound for interacting with the user will be trapped inside the entire machine and cause greater reverberation; and when the diameter of the mounting holes and the sound holes are large and the number is large, the entire machine will not be waterproof.

[0076] Combine the following Figures 1 to 13 , describing an embodiment of the present invention.

[0077] According to an embodiment of the present invention, on one hand, there is provided an electric heater, comprising a housing 1, a mounting member 2, a plurality of side walls 4 and electronic components.

[0078] The housing 1 is provided with a mounting hole 102, a mounting cavity 101, and a drainage hole. The mounting hole 102 is provided at the upper part of the housing 1. The mounting cavity 101 is connected to the mounting hole 102. A mounting member 2 is provided at the mounting hole 102. The drainage hole is provided at the bottom of the housing 1. A plurality of side walls 4 are provided in the housing 1 to enclose a drainage channel 3. One end of the drainage channel 3 is connected to the mounting cavity 101, and the other end is connected to the drainage hole. The electronic device is provided in the housing 1 and is spaced apart from the drainage channel 3.

[0079] During use of the electric heater of the embodiment of the present invention, when water enters the mounting hole 102 on the upper part of the shell 1, the drainage channel 3 can drain the water in the mounting cavity 101 and discharge it through the drainage hole at the bottom of the shell 1, thereby avoiding the problem of water contacting electronic devices and causing short circuits or corrosion of electronic devices, which helps to extend the service life of the electric heater.

[0080] The mounting member 2 is preferably, but not limited to, a microphone.

[0081] In one embodiment, Figure 3 and Figure 4As shown, the electronic device is arranged below the mounting member 2. The side walls 4 include guide ribs 401 and separation ribs 402.

[0082] The guide rib 401 is connected to the bottom wall of the installation cavity 101 and is used to receive water in the installation cavity 101. From top to bottom, the guide rib 401 is inclined in a direction away from the electronic device. One end of the separation rib 402 is connected to the 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 both sides of the separation rib 402.

[0083] By such arrangement, the guide ribs 401 can guide the water flow to avoid the electronic components during the falling process, and the separation ribs 402 can separate the electronic components from the drainage channel 3, thereby preventing the electronic components from contacting with water.

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

[0085] The electric heater further comprises a water-isolating plate 6 .

[0086] The water-blocking plate 6 is arranged in the shell 1, and separates the first cavity 104 and the second cavity 106 which are arranged in a horizontal direction. The first cavity 104 is arranged on the side of the second cavity 106 close to the installation cavity 101, the heater 501 is connected to the water-blocking plate 6, the heating terminal 5011 and the installation cavity 101 are arranged in the first cavity 104, the heating part 5012 and the water outlet are arranged in the second cavity 106, and the bottom of the water-blocking plate 6 is provided with a flow hole 601.

[0087] By such arrangement, the water flow in the drainage channel 3 can enter the second cavity 106 through the flow hole 601 on the water-blocking 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 with drainage holes is separated from the first cavity 104 by the baffle plate 6, avoiding the need to provide drainage holes in the first cavity 104 where electronic devices such as heating terminals 5011 that cannot come into contact with water are provided, thereby further reducing the risk of electronic devices coming into contact with rainwater.

[0089] On this basis, if Figure 1 and Figure 2 As shown, the water-blocking plate 6 can also be used to install the heater 501. The water-blocking plate 6 has various 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] Illustratively, in an optional embodiment, the temperature limiter 502 is disposed below the guide rib 401 and above the heating terminal 5011 .

[0092] In one embodiment, the side walls 4 further include a water guide rib 403. The water guide rib 403 is disposed on the bottom wall of the housing 1, connected to the separation rib 402, and extends toward the flow hole 601.

[0093] By such arrangement, the water guide rib 403 can guide the water from the separation rib 402 toward the flow hole 601, and then guide the water flow to be discharged through the drainage hole to prevent water from accumulating in the housing 1 and causing bacteria to grow or produce odor.

[0094] In one embodiment, a water inlet 109 is provided on the bottom wall of the installation cavity 101 , the water inlet 109 is provided on one side of the installation component 2 , and the first end of the drainage channel 3 is connected to the water inlet 109 .

[0095] By such arrangement, water on the bottom wall of the installation cavity 101 can flow into the drainage channel 3 through the water inlet 109 .

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

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

[0098] In one embodiment, the mounting member 2 is a voice collection device, a sound outlet 105 is provided on a side wall of the housing 1, and the electric heater further includes a voice playback device 7 and a voice control module.

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

[0100] The voice collection device can collect voice instructions, and the voice control module can control the adjustment unit to adjust the heater according to the collected voice instructions. By setting the voice playback device 7, the voice control module can issue interactive instructions according to the collected voice instructions, and play them out through the voice playback device 7. Therefore, the user can adjust the electric heater without going near the electric heater and can obtain the adjustment feedback information of the electric heater, which is convenient to operate and has a good user experience.

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

[0102] In the embodiment of the present application, the voice playback device 7 is arranged on the side wall of the shell 1, and the voice collection device is arranged on the upper part of the shell 1. Therefore, the distance between the voice playback device 7 and the voice collection device is relatively far. The shell 1 prevents the voice played by the voice playback device 7 from being collected by the voice collection device, thereby avoiding crosstalk or reverberation.

[0103] In one embodiment, a partition structure is provided in the shell 1, and the partition structure separates the shell 1 into an upper cavity component 107 and a lower cavity component 108. The upper cavity component 107 and the lower cavity component 108 are arranged in sequence from top to bottom, and the voice playback device 7 is arranged in the lower cavity component 108.

[0104] Part of the voice emitted by the voice broadcast device will remain in the housing 1, and there is a risk that the voice emitted by the voice broadcast device is collected by the voice collection device, causing crosstalk or reverberation.

[0105] The electric heater of the present application is separated into an upper cavity component 107 and a lower cavity component 108 in the shell 1 by a partition structure, and a voice collection device and a voice broadcasting device are arranged in different cavities. When the sound propagates in the lower cavity component, it will be blocked by the partition structure, which effectively reduces the risk of crosstalk or reverberation.

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

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

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

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

[0110] By such arrangement, the heating body 9 can rotate relative to the base, thereby changing the shape of the electric heater to adapt to different usage environments.

[0111] On this basis, the voice player is arranged on the side wall of the base 8 away from the rotation direction of the heating body 9, which can avoid blocking the voice player 7 during the rotation of the heating body 9.

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

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

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

[0115] By such an arrangement, the distance between the voice playback device 7 and the voice collection device can be further increased, thereby reducing the risk that the voice played by the voice playback device 7 is collected by the voice collection device.

[0116] As a convertible implementation, in an embodiment not shown in the drawings, the installation cavity 101 is disposed in the first cavity 104 component.

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

[0118] With such an arrangement, when the electric heater is used in a bathroom or other environment, when water falls onto the top wall of the housing 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 housing 1, and will not flow into the housing 1. Even if a small amount of water penetrates into the housing 1, it can be discharged through the drainage channel 3, and will not accumulate in the housing 1.

[0119] Since the waterproof test is a 360° test without blind spots, the above design can achieve waterproofing in all directions of water flow facing the mounting hole 102 without causing water immersion in electronic devices.

[0120] In addition, by arranging the mounting hole 102 on the top wall of the housing 1, it is also possible to avoid problems such as poor sound reception and inaccurate voice recognition caused by the electric heater being close to the cavity wall.

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

[0122] In summary, the electric heater of the embodiment of the present invention can ensure accurate recognition of the voice function while taking into account the waterproof requirements of the heater. The electric heater of the present invention can meet the IPX4 waterproof grade standard.

[0123] 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.
