[0040] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0041] In order to solve the problem in the prior art that the position of the speech hole on the oil heater affects the appearance of the oil heater, the present application provides an oil heater.

[0042] like Figures 1 to 12As shown, the oil heater includes a panel assembly 10, and the panel assembly 10 includes a panel 11, a decorative assembly 12 and a display panel. The panel 11 has a first mounting recess 111, and the first mounting recess 111 has an inner bottom surface 1111 and an inner peripheral surface 1112 connected to each other. The decorative assembly 12 includes a first decorative plate 121 and a second decorative plate 122 connected to each other, and the first decorative plate 121 is connected to the inner bottom surface 1111 of the first mounting recess 111 through the second decorative plate 122. The display panel is arranged in the first mounting recess 111, and the first decorative plate 121 is located on the side of the display panel away from the first mounting recess 111, and the second decorative plate 122 is arranged around at least part of the display panel and is a non-exterior surface. There is a preset space between the second decorative plate 122 and at least part of the inner peripheral surface 1112, and the second decorative plate 122 has a voice hole 1221, and the voice hole 1221 is connected to the preset space.

[0043] By applying the technical solution of this embodiment, since the second decorative panel 122 is a non-exterior surface, the voice hole 1221 is set on the non-exterior surface so that the position of the voice hole 1221 is relatively hidden, and the user is not easy to notice the voice hole 1221 on the outer surface of the oil heater, thereby solving the problem in the prior art that the position of the voice hole on the oil heater affects the appearance of the oil heater, thereby improving the appearance of the oil heater and the visual experience of the user.

[0044] In this embodiment, by setting the voice hole 1221 on the panel assembly 10, the distance between the human and the machine can be reduced, so that after the user issues a command, the microphone can receive the command immediately and provide timely feedback. At the same time, since the microphone is located close to the display panel, the length of the corresponding wiring of the microphone can be reduced, saving costs, and the wiring can be adjusted in time.

[0045] In this embodiment, the preset space can play a role in guiding sound, making the sound entering from the voice hole 1221 more concentrated, thereby improving the accuracy of voice recognition. At the same time, the connection design between the voice hole 1221 and the preset space can also ensure clear output of sound, so that the user can effectively receive feedback information even at a long distance or in a noisy environment.

[0046] Optionally, there is one voice hole 1221; or, there are multiple voice holes 1221, and the multiple voice holes 1221 are arranged at intervals along the extension direction and / or width direction of the second decorative plate 122. In this way, the above arrangement makes the number of voice holes 1221 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff. At the same time, the above arrangement of multiple voice holes 1221 can improve the range and accuracy of voice reception, and ensure that voice commands are accurately received even in a larger room, thereby enhancing the intelligent control performance of the oil heater.

[0047] In other embodiments not shown in the drawings, by setting voice holes at multiple positions, not only the effective area of ​​voice reception is expanded, but also sound reflection and interference can be reduced. Even if the user issues instructions at different locations in the room, the oil heater can accurately recognize and respond.

[0048] Optionally, the aperture of the voice hole 1221 is greater than or equal to 4 mm and less than or equal to 6 mm. In this way, the aperture design can not only ensure sufficient sound throughput, but also prevent dust and foreign matter from entering and protect internal components. At the same time, the selection of an aperture of 4 to 6 mm is based on a comprehensive consideration of sound propagation characteristics and dustproof effects, which not only ensures the clarity and penetration of the sound, but also effectively blocks the intrusion of common dust particles. This design ensures the long-term stability and reliability of the voice recognition component.

[0049] In this embodiment, the diameter of the speech hole 1221 is 5 mm.

[0050] It should be noted that the selection of the aperture of the voice hole 1221 is not limited to this, and can be adjusted according to working conditions and usage requirements. Optionally, the aperture of the voice hole 1221 is 4.2 mm, or 4.5 mm, or 4.8 mm.

[0051] like Figure 4 and Figure 5 As shown, the inner circumference 1112 includes a first surface 11121, a second surface 11122, a third surface 11123 and a fourth surface 11124 connected end to end, the first surface 11121 is arranged opposite to the third surface 11123, and the second surface 11122 is arranged opposite to the fourth surface 11124; wherein the second decorative plate 122 is arranged opposite to the first surface 11121, at least part of the second surface 11122 and at least part of the fourth surface 11124 to form a preset space, and the voice hole 1221 is arranged opposite to the first surface 11121. In this way, the above arrangement enables the preset space to be used as a channel for sound, thereby improving the clarity of speech. At the same time, the above arrangement improves the appearance of the panel assembly 10.

[0052] Specifically, the above-mentioned setting of the preset space is similar to an acoustic pipe, which can effectively reduce the attenuation of sound during the propagation process, so that the sound entering from the voice hole 1221 is more direct and clear, which can significantly improve the accuracy and efficiency of user operations.

[0053] In this embodiment, the distance between the first surface 11121 and the third surface 11123 gradually decreases, and the distance between the second surface 11122 and the fourth surface 11124 gradually decreases from the outside to the inside of the panel assembly 10. In this way, the above arrangement can form a focusing effect of sound, further improving the accuracy of speech recognition.

[0054] Specifically, through the design of gradually reducing the distance, an effect similar to acoustic focusing can be formed in the preset space, so that the sound entering from the voice hole 1221 is enhanced at the focal point, which can effectively improve the response speed and accuracy of voice control and bring users a more convenient smart life experience.

[0055] Optionally, the first decorative plate 121 is a flat plate; and / or the second decorative plate 122 is a curved plate, which is inclined toward the display panel relative to the inner bottom surface 1111. In this way, the combination of the flat plate and the curved plate not only ensures the aesthetics of the oil heater, but also avoids the risk of the voice hole 1221 being directly exposed to the external environment through the inclined setting of the curved plate.

[0056] In this embodiment, the first decorative plate 121 is a flat plate, and the second decorative plate 122 is an arc-shaped plate, which is inclined relative to the inner bottom surface 1111 toward the display panel.

[0057] like Fig.11 and Fig.12 As shown, the voice hole 1221 is a microphone hole, and the oil heater further includes a base assembly 20, and the base assembly 20 includes a base body 21 and a speaker 22. Among them, the base body 21 has a through hole, and the speaker 22 is arranged on the base body 21, and the speaker 22 is arranged corresponding to the through hole. In this way, the use of the microphone hole and the speaker 22 enables the oil heater to achieve two-way voice interaction, and the user can not only issue instructions, but also receive feedback information, which enhances the interactivity and user experience of the oil heater.

[0058] In this embodiment, the design of two-way voice interaction enables the oil heater to not only serve as a receiver of voice commands, but also to provide timely feedback on execution results or status information, thereby enhancing the interaction between the user and the device and improving the safety and convenience of operation.

[0059] like Fig.12 As shown, the seat 21 includes a seat body 211 and an extension plate 212. The seat body 211 has a through hole. The extension plate 212 is arranged on the seat body 211, and the speaker 22 is detachably arranged on the extension plate 212. In this way, the detachable design of the speaker 22 facilitates the user to replace or upgrade the speaker as needed, and also makes the structure of the seat 21 simpler, easier to process and realize, and reduces the processing cost and difficulty of the seat 21.

[0060] like Figures 8 to 10 As shown, the oil heater further includes a shell assembly 30, and the shell assembly 30 includes a cover 31. The cover 31 is disposed outside at least a portion of the base assembly 20, and the cover 31 has a second mounting recess, and the panel assembly 10 is disposed in the second mounting recess. The through hole is located in the cover 31. In this way, the above-mentioned covering design of the shell assembly 30 can protect the device located therein, so as to extend the service life of the oil heater.

[0061] In this embodiment, the seat body 21 is pre-installed on the housing assembly 30 , so that an accommodating cavity is formed between the seat body 21 and the housing assembly 30 to accommodate the speaker 22 .

[0062] Optionally, the panel assembly 10 is detachably connected to the cover body 31; and / or the base assembly 20 is detachably connected to the cover body 31. In this way, the above detachable connection method enables the oil heater to meet the user's demand for personalized appearance. The user can choose a panel assembly 10 or a base assembly 20 of different colors and materials according to the interior decoration style or personal preference.

[0063] Optionally, a limiting portion is provided on the inner surface of the cover 31, and the limiting portion is used to limit and stop the speaker 22. In this way, the above-mentioned setting of the limiting portion can ensure the stability of the speaker 22 during use, avoid displacement due to vibration or collision, and improve the safety and reliability of the product. At the same time, the above-mentioned setting of the limiting portion ensures that the speaker 22 can be aligned with the through hole so that sound can be transmitted through the through hole.

[0064] In this embodiment, the base assembly 20 and the cover body 31 are connected by screws, and the limiting portion is arranged at the screws to ensure that the speaker 22 is arranged corresponding to the through hole.

[0065] like Figures 8 to 10 As shown, the cover body 31 includes a panel 311 and an upper cover 312. The panel 311 has a second mounting recess. The upper cover 312 is mounted on the first end of the panel 311, and the second end of the panel 311 has an opening, and the base assembly 20 is arranged at the opening. In this way, the above arrangement not only ensures the overall beauty of the oil heater, but also facilitates the installation and disassembly of the base assembly 20 through the design of the opening, which can improve the flexibility and maintenance efficiency of the equipment, and also facilitates the user to move the oil heater between different rooms or locations, thereby enhancing the practicality and flexibility of the product. In addition, the above arrangement makes the structure of the cover body 31 simpler, easier to process and realize, and reduces the processing cost and difficulty of the cover body 31.

[0066] Optionally, the oil heater further includes a voice module. The voice module is located in the panel assembly 10, and the voice module is arranged corresponding to the voice hole 1221. In this way, the setting of the voice module enables the oil heater to have an intelligent voice control function, and the user can adjust the temperature, set the timer, etc. through voice commands, which greatly improves the convenience and comfort of the user.

[0067] In this embodiment, the above-mentioned position setting of the speaker 22 and the voice hole can be far away from the heating part of the oil heater, which ensures that the speaker 22 and the voice module can be used normally on the one hand, and prolongs the service life of the speaker 22 and the voice module on the other hand. At the same time, the above-mentioned setting makes the distance between the two farther, thereby reducing the crosstalk problem between the two, and simultaneously meeting the EMC test requirements.

[0068] In this embodiment, the speaker 22 and the microphone are not opened on the outer surface of the oil heater, but corresponding through holes are added on the seat 21 and the panel assembly 10. On the one hand, it can reduce the influence of the wall thickness of the injection molded part on sound transmission and even affect the sound quality. On the other hand, the position of the above-mentioned openings is relatively hidden and not easy to detect, and thus does not affect the appearance effect, so that the product maintains the original condition but adds corresponding new functions to meet the design requirements.

[0069] like Figure 1 and Fig.10 As shown, the oil heater further includes a main board 40, a stand 50 and a heating part 60. The main board 40 is disposed in the first mounting recess 111.
