Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to heating devices. Background Technology

[0002] Oil-filled radiators, as heating devices with excellent heating performance and ease of use, have become increasingly widely used. Considering that oil-filled radiators are mainly used at night in cold winters, products that support offline voice control are gaining popularity in the market to avoid users having to get up to operate them in the middle of the night. With the increasing prevalence of smart homes, adding voice functionality to traditional home appliances has become a key path to enhance product competitiveness. Currently, the most common approach to upgrading heating devices like oil-filled radiators to voice functionality is to use an external, independent voice module. However, this approach often affects the overall aesthetics of the product, increases assembly complexity, and poses reliability risks. Alternatively, a large-scale redesign of the internal structure can be implemented, but this leads to increased development costs, longer production cycles, and makes it difficult to reuse existing mature components and supply chain systems, resulting in resource waste. Summary of the Invention

[0003] In view of this, the present invention provides a heating device to solve the problem of high assembly complexity and easy waste of resources in the process of upgrading heating devices such as oil heaters to voice control.

[0004] This invention provides a heating device, comprising: case; A voice module is disposed within the housing, and the voice module includes a speaker and a microphone; An integrated bracket is fixed inside the housing; The integrated bracket is provided with a first holding part and a second holding part, the speaker is fixed to the first holding part, and the microphone is fixed to the second holding part.

[0005] Beneficial Effects: By introducing a single integrated bracket and using its first and second retaining parts to fix the speaker and microphone respectively, the voice module is integrated and modularized. Only one integrated bracket is needed to assemble the voice module, achieving integration and assembly with minimal additional parts. No modifications to other existing structural components are required, preserving the integrity of the original design to the greatest extent possible. This achieves the goal of adding voice functionality to heating devices while simplifying assembly and ensuring structural compatibility. It solves the problem of high assembly complexity and resource waste during voice-enabled upgrades to heating devices.

[0006] In one alternative embodiment, the integrated support is provided with a guiding structure configured to guide heat flow preferentially along the peripheral path of the integrated support.

[0007] Beneficial effects: The guiding structure on the integrated bracket provides a low thermal resistance path for heat flow along the bracket's sidewalls, actively guiding the heat flow direction and prioritizing its flow along the outer perimeter of the bracket. This not only reduces obstacles encountered by the heat flow, allowing for smoother heat conduction along the outer sidewalls, but also reduces the risk of internal heat obstruction or disordered diffusion by optimizing the heat flow path. This ensures that heat is dissipated more smoothly and in a more controllable manner, preventing heat accumulation in critical areas inside the integrated bracket. This better meets overall heat dissipation requirements and ensures stable operating temperatures for components such as speakers and microphones on the integrated bracket.

[0008] In one optional embodiment, the guide structure includes a guide ramp, the angle α between the guide ramp and the mounting reference plane L of the integrated bracket being 30° to 45°; wherein the mounting reference plane L is parallel to the bottom surface of the integrated bracket.

[0009] Beneficial effects: The angle α between the guide ramp in the guide structure and the mounting reference plane L of the integrated bracket is 30° to 45°, which allows hot air to rise more easily along the ramp, forming a smooth airflow channel. This not only reduces airflow eddies and flow obstruction, directly improving heat dissipation efficiency, but also helps reduce the temperature per unit area by increasing the contact surface area, avoiding localized high temperatures and effectively solving the temperature rise problem. At the same time, this ramp structure can reduce material usage while ensuring heat dissipation effect, achieving a dual optimization of heat dissipation performance and material cost.

[0010] In one alternative embodiment, the first retaining portion includes a limiting structure that engages with the speaker sidewall.

[0011] Beneficial effects: By setting corresponding limiting structures on the sidewalls of the speaker for limiting and coordinating, precise positioning and stable holding of the core acoustic components are achieved. The limiting structure of the first holding part cooperates with the sidewalls of the speaker; it can effectively limit the displacement of the speaker inside the equipment, preventing it from shifting due to vibration, collision, etc. At the same time, the limiting cooperation reduces deviations during the assembly process, improves the assembly accuracy and consistency of the product, thereby ensuring the stable sound performance of the speaker, reducing the interference caused by speaker displacement to the surrounding structure, and improving the overall structural stability and reliability of the equipment.

[0012] In one alternative embodiment, the second retaining portion includes a limiting structure that engages with the microphone sidewall.

[0013] Beneficial effects: By setting corresponding limiting structures on the side walls of the microphone for limiting and coordinating, precise positioning and stable holding of the core acoustic components are achieved. The limiting structure of the second holding part cooperates with the side wall of the microphone; it can effectively limit the displacement of the microphone inside the device, preventing it from shifting due to vibration, collision, etc. At the same time, the limiting cooperation reduces deviations during the assembly process, improves the assembly accuracy and consistency of the product, thereby ensuring the normal sound reception function of the microphone, and reducing the interference caused by microphone displacement to the surrounding structure, improving the overall structural stability and reliability of the device.

[0014] In one alternative embodiment, the limiting structure protrudes from the integrated bracket.

[0015] Beneficial effects: By setting a protruding limiting structure on the integrated bracket, components such as speakers, microphones, and speech detection boards can be kept at a certain distance from the outer perimeter of the integrated bracket. This effectively isolates heat transfer between the components and the integrated bracket, preventing external heat from affecting the operation of the voice module. This satisfies the internal temperature design requirements of the speakers, microphones, and other components, ensuring stable operation of the voice module in a suitable temperature environment.

[0016] In one alternative embodiment, the housing includes a face mask and a panel; the two ends of the integrated bracket are respectively connected to the face mask and the panel.

[0017] Beneficial Effects: By connecting the two ends of the integrated bracket to the faceplate and panel of the housing respectively, the existing housing structure features are fully utilized to add integrated functionality. The voice module is assembled directly using the existing structure of the faceplate and panel, without significant modifications to the original design. Existing materials remain usable, thus minimizing the types and quantities of new materials. Since only the integrated bracket needs to be added to simultaneously meet the assembly and positioning requirements of the speaker and microphone components, the increase in the number of parts is effectively controlled, assembly time is shortened, and production efficiency is improved and overall costs are optimized while adding voice functionality.

[0018] In one alternative embodiment, the gap between the integrated bracket and the mask is 0.2 mm.

[0019] Beneficial effects: Maintaining a 0.2mm gap between the integrated bracket and the mask provides the necessary tolerance space for the assembly process, avoiding assembly interference or stress deformation that may occur due to excessive fitting between the two, ensuring smooth and efficient production, and reserving reasonable space for heat flow without affecting structural stability, thereby indirectly maintaining the stability of its acoustic performance and heat dissipation effect.

[0020] In one optional embodiment, the integrated bracket and the mask form a sound cavity, and the speaker is housed within the sound cavity; the mask or the integrated bracket has a sound hole communicating with the sound cavity.

[0021] Beneficial Effects: The integrated bracket and mask create a sealed acoustic cavity, housing the speaker and providing a dedicated and stable operating environment. This not only reduces direct heat transfer from the external environment to the speaker, improving temperature exchange between the speaker and its surroundings and ensuring a suitable operating temperature, but also enhances the speaker's temperature resistance. Furthermore, it effectively focuses the sound emitted by the speaker, reducing sound wave diffusion and loss during propagation, thereby improving clarity and loudness. The sound holes on the mask or integrated bracket directly connect to the acoustic cavity, providing a dedicated propagation channel for the sound emitted by the speaker within. This ensures efficient and lossless sound transmission, further guaranteeing the speaker's acoustic performance and providing users with a clear and transparent listening experience. Moreover, while ensuring sound transparency, it effectively prevents foreign objects from directly entering the cavity, achieving a unified function of sound transmission and protection.

[0022] In one alternative embodiment, the microphone's pickup end protrudes from the limiting structure and is positioned toward the panel.

[0023] Beneficial effects: The microphone's pickup end protrudes from the limiting structure and faces the panel, allowing it to avoid potential obstruction from the structure and ensuring a wider pickup range. This ensures an unobstructed pickup channel and effectively prevents sound attenuation or coloration caused by structural obstruction. Furthermore, the panel orientation allows the microphone to directly point at the user's sound source, reducing environmental noise interference from other directions. This allows the microphone to more accurately capture the target sound, improving pickup sensitivity and signal-to-noise ratio, thus ensuring the clarity and reliability of voice interaction. Simultaneously, the protruding design also prevents heat buildup near the limiting structure from affecting the microphone's pickup sensitivity, ensuring stable acoustic performance.

[0024] In one alternative embodiment, the microphone's pickup end protrudes 0.2 mm above the limiting structure.

[0025] Beneficial effects: The microphone pickup end protrudes 0.2mm above the limiting structure, which ensures that the pickup end avoids obstruction by the limiting structure, ensuring an unobstructed pickup channel to improve the accuracy of sound capture, effectively preventing the limiting structure from blocking and reflecting sound waves, and ensuring clear acquisition of the original sound source; at the same time, by controlling the height of the protrusion, it avoids structural interference or additional space occupation caused by excessive protrusion, taking into account the compactness and stability of the overall structure.

[0026] In one alternative embodiment, the panel is provided with a pickup hole, which is positioned directly opposite the pickup end of the microphone.

[0027] Beneficial effects: The microphone aperture on the panel is directly opposite the microphone pickup end, providing a direct and unobstructed channel for sound propagation. This allows external sounds to be transmitted to the microphone pickup end more efficiently and accurately, reducing sound loss and interference during propagation, improving pickup sensitivity and signal-to-noise ratio, and ensuring the clarity and reliability of voice interaction. Furthermore, the direct alignment of the microphone aperture and the microphone pickup end also minimizes the entry of ambient noise from non-target directions into the microphone, further improving the microphone's pickup clarity and anti-interference capabilities, and ensuring high-quality voice signal acquisition.

[0028] In one alternative implementation, the distance between the microphone and the speaker is greater than or equal to 40 mm.

[0029] Beneficial effects: Setting the distance between the microphone and speaker to be greater than or equal to 40mm not only strictly meets the requirements for the distance between the two in electrical control experiments, but also effectively reduces crosstalk interference caused by the speaker when it emits sound, ensuring the clarity of microphone pickup, by optimizing the layout of the voice module. At the same time, this distance design can also meet the requirements of electromagnetic compatibility (EMC) testing, avoiding electromagnetic interference problems caused by insufficient component spacing, and ensuring the stable operation of the voice module and the whole machine.

[0030] In one alternative embodiment, the integrated bracket is provided with a cable management channel; the wires are fixed in the cable management channel and connected to the speaker and / or the microphone.

[0031] Beneficial effects: The cable management channels on the integrated bracket can neatly store and fix the power cords of the microphone and speaker, ensuring that the wiring is neat and tidy, and making the wiring operation of the whole machine more convenient. It can also meet the safety requirements of the equipment by standardizing the wiring layout, avoiding safety hazards or assembly difficulties caused by messy wiring, providing a clear wiring path for subsequent maintenance, and improving the internal tidiness.

[0032] In one alternative implementation, the heating device is an oil-filled radiator. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0041] According to an embodiment of the present invention, a heating device is provided, including a housing 1, a voice module 2, and an integrated bracket 3; the voice module 2 is disposed inside the housing 1, and the voice module 2 includes a speaker 21 and a microphone 22; the integrated bracket 3 is fixed inside the housing 1; the integrated bracket 3 is provided with a first holding part 31 and a second holding part 32, the speaker 21 is fixed to the first holding part 31, and the microphone 22 is fixed to the second holding part 32.

[0042] In the above embodiments, by introducing a single integrated bracket 3 and using the first retaining part 31 and the second retaining part 32 on it to fix the speaker 21 and the microphone 22 respectively, the integration and modularization of the voice module 2 are achieved. Only one integrated bracket 3 is needed to complete the assembly of the voice module 2, achieving integration and assembly of the voice module 2 with the fewest possible new parts. No modifications are required to other existing structural components of the device, preserving the integrity of the original design to the greatest extent possible. This achieves the goal of adding voice functionality to the heating device while also simplifying assembly and ensuring structural compatibility. It solves the problem of high assembly complexity and resource waste during the voice-enabled upgrade of heating devices.

[0043] In another embodiment of this invention, the speaker 21 may be fixed to the second holding part 32 and the microphone 22 may be fixed to the first holding part 31; wherein the integrated bracket 3 and the panel 12 form a sound cavity, and the speaker 21 is housed in the sound cavity; the pickup end of the microphone 22 protrudes from the limiting structure and is positioned toward the mask 11.

[0044] Specifically, the integrated bracket 3 is a one-piece injection molded part.

[0045] Specifically, the voice module 2 also includes a voice detection board 23, which is mounted on the integrated bracket 3.

[0046] In one alternative embodiment, the first retaining part 31 includes a limiting structure that engages with the side wall of the speaker 21.

[0047] In the above embodiments, by setting a corresponding limiting structure on the side wall of the speaker 21 for limiting cooperation, the precise positioning and stable holding of the core acoustic component are achieved. The limiting structure of the first holding part 31 cooperates with the side wall of the speaker 21; it can effectively limit the displacement of the speaker 21 inside the device, avoid its positional shift due to vibration, collision, etc. At the same time, the limiting cooperation reduces the deviation in the assembly process, improves the product assembly accuracy and consistency, thereby ensuring the stable sound output of the speaker 21, and reducing the interference caused by the displacement of the speaker 21 to the surrounding structure, improving the overall structural stability and reliability of the device.

[0048] In one alternative embodiment, the second retaining portion 32 includes a limiting structure that engages with the sidewall of the microphone 22.

[0049] In the above embodiments, by setting corresponding limiting structures on the side walls of the microphone 22 for limiting cooperation, precise positioning and stable holding of the core acoustic component are achieved. The limiting structure of the second holding part 32 cooperates with the side wall of the microphone 22; it can effectively limit the displacement of the microphone 22 inside the device, avoid its positional shift due to vibration, collision, etc. At the same time, the limiting cooperation reduces the deviation during the assembly process, improves the product assembly accuracy and consistency, thereby ensuring the normal sound reception function of the microphone 22, and reducing the interference caused by the displacement of the microphone 22 to the surrounding structure, improving the overall structural stability and reliability of the device.

[0050] In one embodiment, the limiting structure protrudes from the integrated bracket 3.

[0051] In the above embodiment, by providing protruding ribs 33 on the integrated bracket 3, components such as the speaker 21, microphone 22, and speech detection board can be kept at a certain distance from the outer perimeter of the integrated bracket sidewall. This effectively isolates heat transfer between the speaker 21, microphone 22, speech detection board, and other components and the integrated bracket sidewall, preventing external heat from affecting the operation of the voice module 2, thereby meeting the internal temperature design requirements of components such as the speaker 21 and microphone 22, and ensuring stable operation of the voice module 2 in a suitable temperature environment.

[0052] In a specific implementation, the limiting structure includes a rib 33 protruding from the integrated bracket 3. The rib 33 protrudes upward from the bottom plate of the integrated bracket 3 and surrounds the speaker 21 and microphone 22.

[0053] In one embodiment, the integrated support 3 is provided with a guiding structure configured to guide heat flow preferentially along the peripheral path of the integrated support.

[0054] In the above embodiments, the guiding structure on the integrated bracket 3 provides a low thermal resistance path for heat flow along the sidewall of the integrated bracket, actively guiding the direction of heat flow so that it preferentially flows along the outer path of the integrated bracket. This not only reduces the obstacles encountered by the heat flow during its flow, allowing it to be conducted more smoothly along the outer sidewall, but also reduces the risk of heat flow being blocked or spreading disorderly inside the bracket by optimizing the heat flow path. This allows heat to be discharged more smoothly and in a more controllable manner, preventing heat from accumulating in key areas inside the integrated bracket. This better meets the overall heat dissipation requirements and ensures the stable operating temperature of various components such as the speaker 21 and microphone 22 on the integrated bracket 3.

[0055] In one embodiment, the guide structure includes a guide ramp 341, and the angle α between the guide ramp 341 and the mounting reference surface L of the integrated bracket is 30° to 45°; wherein the mounting reference surface L is parallel to the bottom surface of the integrated bracket.

[0056] In the above embodiments, the angle α between the guiding ramp 341 in the guiding structure and the mounting reference plane L of the integrated bracket is 30° to 45°, which allows hot air to rise more easily along the ramp, forming a smooth airflow channel. This not only reduces airflow eddies and flow obstruction, directly improving heat dissipation efficiency, but also helps reduce the temperature per unit area by increasing the contact surface area, avoiding localized high temperatures and effectively solving the temperature rise problem. At the same time, this ramp structure can reduce material usage while ensuring heat dissipation effect, achieving a dual optimization of heat dissipation performance and material cost.

[0057] Specifically, such as Figure 8 As shown, the integrated bracket 3 has an irregular structure, and there are two sets of guide slopes 341. The angle α between the two sets of guide slopes 341 and the mounting reference surface L of the integrated bracket is 30° to 45°.

[0058] In one embodiment, the housing 1 includes a face mask 11 and a panel 12; the two ends of the integrated bracket 3 are respectively connected to the face mask 11 and the panel 12.

[0059] In the above embodiment, by connecting the two ends of the integrated bracket 3 to the faceplate 11 and panel 12 of the housing 1 respectively, the existing structural features of the housing 1 are fully utilized to add integrated functionality. The voice module 2 is assembled directly using the existing structures of the faceplate 11 and panel 12, without requiring significant modifications to the original design. Existing materials remain usable, thus minimizing the types and quantities of new materials. Since only the integrated bracket 3 needs to be added to simultaneously meet the assembly and positioning requirements of the speaker 21 and microphone 22 components, the increase in the number of parts is effectively controlled, and assembly time is shortened. While adding voice functionality, production efficiency is improved and overall costs are optimized.

[0060] Preferably, the panel 12 is provided with a display panel 122 and an operation panel 123.

[0061] In one embodiment, the integrated bracket 3 is connected to the face mask 11 and / or panel 12 via fasteners 4.

[0062] In the above embodiments, the integrated bracket 3 is connected to the mask 11 and / or panel 12 via fasteners 4, which can securely fix the integrated structure to the mask 11 and / or panel 12. This ensures that the speaker 21 is fully assembled with the mask 11, allowing the speaker 21 to fit tightly against the inner surface of the mask 11, avoiding structural loosening or sound interference caused by assembly gaps, thereby ensuring the stable operation of the speaker 21 assembly.

[0063] In a specific implementation, by setting screw posts 5 on the panel 12 and the face mask 11 respectively, and using screws and other fasteners 4 to fasten to the corresponding screw posts 5, the assembly positioning and installation limit of the integrated bracket 3 are achieved.

[0064] Specifically, the mask 11 consists of a mask body 112, an upper cover 113, and a base 114.

[0065] In one embodiment, the gap between the integrated bracket 3 and the mask 11 is 0.2 mm.

[0066] In the above embodiment, a gap of 0.2mm is maintained between the integrated bracket 3 and the mask 11, which provides the necessary tolerance space for the assembly process, avoids assembly interference or stress deformation that may occur due to excessive fitting between the two, ensures smooth and efficient production, and can also reserve reasonable space for heat flow without affecting structural stability, thereby indirectly maintaining the stability of its acoustic performance and heat dissipation effect.

[0067] In one embodiment, the integrated bracket 3 and the mask 11 form a sound cavity, and the speaker 21 is housed within the sound cavity.

[0068] In the above embodiment, the integrated bracket 3 and the mask 11 form a closed acoustic cavity, which houses the speaker 21, providing the speaker 21 with a dedicated and stable working environment. This not only reduces the direct transfer of heat from the external environment to the speaker 21, improving the temperature transfer between the speaker 21 and the surrounding environment, and ensuring that the speaker 21 maintains a suitable working temperature, but also effectively concentrates the sound emitted by the speaker 21, reducing the diffusion and loss of sound waves during propagation, thereby improving the clarity and loudness of the sound.

[0069] In one embodiment, the mask 11 or the integrated bracket 3 has a sound hole 111 that communicates with the acoustic cavity.

[0070] In the above embodiments, the sound holes 111 on the mask 11 or integrated bracket 3 are directly connected to the acoustic cavity, providing a dedicated propagation channel for the sound emitted by the speaker 21 inside the acoustic cavity. This ensures that the sound generated by the speaker 21 can be transmitted outward efficiently and without loss, further guaranteeing that the acoustic performance of the speaker 21 can be fully utilized, and ensuring that the user obtains a clear and transparent listening experience. Furthermore, while ensuring sound transparency, it effectively prevents foreign objects from directly entering the cavity, achieving an integration of sound transmission and protection.

[0071] Specifically, to ensure the best acoustic output and long-term reliability of the speaker 21, the opening size of the sound hole 111 should be minimized as much as possible while ensuring that the sound is fully released; this will effectively prevent dust from falling into the speaker 21, thereby avoiding sound quality degradation caused by dust accumulation and ensuring the output quality and long-term stability of the speaker 21.

[0072] In one embodiment, the pickup end of the microphone 22 protrudes from the limiting structure and is positioned toward the panel 12.

[0073] In the above embodiment, the microphone 22's pickup end protrudes from the limiting structure and faces the panel 12, allowing the pickup end to avoid potential obstruction caused by the limiting structure, ensuring a wider pickup range and unobstructed pickup channel. This effectively avoids sound attenuation or coloration caused by structural obstruction. Furthermore, its orientation towards the panel 12 allows the microphone 22 to be directly aimed at the user's sound source, reducing environmental noise interference from other directions. This allows the microphone 22 to more accurately capture the target sound, improving pickup sensitivity and signal-to-noise ratio, thereby ensuring the clarity and reliability of voice interaction. Simultaneously, the protruding design from the limiting structure also prevents heat buildup near the limiting structure from affecting the microphone 22's pickup sensitivity, ensuring stable acoustic performance.

[0074] Specifically, the pickup end of the microphone 22 protrudes from the rib 33.

[0075] In one embodiment, the pickup end of the microphone 22 protrudes 0.2 mm above the limiting structure.

[0076] In the above embodiment, the microphone 22's pickup end protrudes 0.2mm above the rib, which not only ensures that the pickup end avoids obstruction by the limiting structure and ensures that the pickup channel is unobstructed to improve the accuracy of sound capture, but also effectively prevents the limiting structure from obstructing and reflecting sound waves, thus ensuring the clear acquisition of the original sound source; it also avoids structural interference or additional space occupation due to excessive protrusion by controlling the height of the protrusion, thus taking into account the compactness and stability of the overall structure.

[0077] Specifically, the pickup end of the microphone 22 protrudes 0.2mm above the rib 33.

[0078] In specific implementation methods, such as Figure 7 As shown, the microphone 22 is mounted in the upper area of ​​the integrated bracket 3, and the receiving cavity formed by the circumferential ribs 33 provides precise positioning and fixation. To achieve clear and accurate sound pickup, the microphone 22 must be in close contact with the inner wall of the panel 12. Therefore, in the structural design, the pickup end of the microphone 22 is 0.2mm higher than the mounting plane of the integrated bracket 3, so as to ensure that when the integrated bracket 3 is assembled to the mask 11, the microphone 22 can first contact the corresponding structure on the panel 12, and then the locking force is applied by fasteners such as screws 4 to strengthen its tight fit with the panel 12, thereby ensuring the stability and reliability of sound pickup performance at both mechanical and acoustic levels.

[0079] In one embodiment, the panel 12 is provided with a pickup hole 121, which is positioned directly opposite the pickup end of the microphone 22.

[0080] In the above embodiment, the pickup hole 121 on the panel 12 is directly opposite the pickup end of the microphone 22, providing a direct and unobstructed channel for sound propagation. This allows external sounds to be transmitted to the pickup end of the microphone 22 more efficiently and accurately, reducing sound loss and interference during propagation, improving pickup sensitivity and signal-to-noise ratio, and ensuring the clarity and reliability of voice interaction. Furthermore, the direct alignment of the pickup hole 121 and the pickup end of the microphone 22 also minimizes the entry of ambient noise into the microphone 22 from non-target directions, further improving the pickup clarity and anti-interference capability of the microphone 22, and ensuring high-quality acquisition of voice signals.

[0081] Specifically, to ensure the best sound pickup performance and long-term reliability of the microphone 22, the opening of the pickup hole 121 should be minimized as much as possible while allowing sound waves to pass through without obstruction. This effectively prevents dust from falling into the voice module 2, thereby avoiding sound quality degradation caused by dust accumulation and ensuring the long-term stable sound pickup quality of the microphone 22.

[0082] In one embodiment, the distance between the microphone 22 and the speaker 21 is greater than or equal to 40 mm.

[0083] In the above embodiment, the distance between the microphone 22 and the speaker 21 is set to be greater than or equal to 40mm. This not only strictly meets the requirements for the distance between the two in the electrical control experiment, but also effectively reduces crosstalk interference caused by the speaker 21 when it emits sound by optimizing the layout of the voice module 2, thus ensuring the clarity of the microphone 22's sound pickup. At the same time, this distance design can also simultaneously meet the electromagnetic compatibility (EMC) test requirements, avoiding electromagnetic interference problems caused by insufficient component spacing, and ensuring the stable operation of the voice module 2 and the entire device.

[0084] In a specific implementation, the microphone 22 is positioned above the speaker 21, which can reduce the acoustic interference of the speaker 21 to the microphone 22 by utilizing the spatial position difference and optimize the sound reception effect.

[0085] In one embodiment, the integrated bracket 3 is provided with a cable management channel 35; the wires are fixed in the cable management channel 35 and connected to the speaker 21 and / or microphone 22.

[0086] In the above embodiment, the cable management groove 35 opened on the integrated bracket 3 can orderly store and fix the power cords of the microphone 22 and the speaker 21, which not only ensures that the wiring is neat and tidy, but also ensures the rationality and consistency of the wiring, making the whole machine wiring operation more convenient. It can also meet the equipment safety requirements by standardizing the wiring layout, avoiding safety hazards or assembly difficulties caused by messy wiring, providing a clear wiring path for subsequent maintenance, and improving the internal tidiness.

[0087] In one embodiment, the heating device is an oil-filled radiator.

[0088] During the installation of the speaker 21 and microphone 22, the speaker 21 and microphone 22 are first pre-fixed on the integrated bracket 3.
