Description

Technical Field

[0001] This utility model relates to the technical field of bathroom heater equipment, specifically a centrifugal annular vector air outlet multifunctional heater. Background Technology

[0002] Traditional heaters are relatively simple in function, typically only providing basic heating, which fails to meet the modern family's demand for comfort and multifunctionality. Existing heater technologies suffer from the following main problems: Traditional heaters typically have a single airflow mode, meaning they cannot switch between gentle, direct airflow and strong, direct airflow, making them unsuitable for users' actual needs.

[0003] With limited heating modes, most heaters only offer a single heating level and cannot flexibly switch between rapid heating and energy-saving constant temperature, making it difficult to adapt to heating needs in different environments.

[0004] Low functional integration: Existing heaters typically only have heating functions and lack multi-functional integration such as ventilation, lighting, and audio playback, which cannot meet users' needs for integrated smart home appliances.

[0005] The air intake is too small, resulting in poor air exchange efficiency.

[0006] In summary, existing indoor heaters have significant shortcomings in terms of air outlet modes, heating flexibility, functional integration, and air intake, making it difficult to meet users' needs for comfortable, convenient, and multifunctional heating devices. Utility Model Content

[0035] Advantageously, the baffle assembly includes a baffle 48 hinged to one side of the vent 32. The baffle 48 is rotated by a sector gear power structure. After the baffle 48 rotates, it can close the vent 32 and connect the second air duct 38 with the air outlet 36 to achieve the air outlet function. Alternatively, the baffle 48 can be rotated to disconnect the second air duct 38 from the air outlet 36, and then connect the second air duct 38 with the vent 32 to achieve the ventilation function.

[0036] Advantageously, the sector tooth power structure includes a side plate 47 fixedly disposed on one side of the baffle 48, a sector tooth 46 disposed on the outer edge of the side plate 47, a second motor 49 disposed inside the indoor heater main unit 11, a second drive gear 52 fixedly disposed on the output shaft of the second motor 49, and the second drive gear 52 meshing with the sector tooth 46.

[0041] Beneficially, this also includes, for example Figure 13 The control switch shown is electrically connected to the heater, specifically to the third motor 51, the first motor 43, the second motor 49, the first heating block 58, the second heating block 59, the third heating block 62, the fourth heating block 63, the fifth heating block 64, and the indoor heater panel 12, so as to realize the start and stop of various functions, as well as the switching of ventilation modes, etc.

[0042] When the device is in operation, it can realize functions such as ventilation, air blowing, lighting and music. The indoor heater main unit 11 draws air from the gap on the upper side of the indoor heater panel 12, and after passing through the second air inlet 35, the second air duct 38 and the vent 32, it realizes ventilation. After passing through the second air inlet 35, the second air duct 38 and the air outlet 36, it realizes air blowing. After passing through the second air inlet 35, the first air duct 37 and the air outlet 36, it realizes air blowing. When blowing air, depending on the position of the guide plate 41 on the air outlet 36 and the PTC heating block assembly, it can generate imperceptible wind and direct strong wind. The speaker 22, the vent 23 and the speaker cover 26 in the indoor heater panel 12 form a sound unit, the first light ring 27, the second light ring 28 and the lighting lamp 29 form a lighting unit, and the vent 23 and the air outlet 36 are connected to form a ventilation unit.

[0043] When the device is ventilating, the second motor 49 drives the second drive gear 52 to rotate. After the second drive gear 52 meshes with the sector gear 46, it causes the side plate 47 and the baffle 48 to rotate, thereby isolating the second air duct 38 and the air outlet 36, and connecting the second air duct 38 with the ventilation port 32. After the centrifugal fan blades 34 in the second air duct 38 are driven to rotate by the third motor 51, they can draw air from the second air inlet 35 and blow it out from the ventilation port 32, thus realizing the ventilation function.

[0044] When the device blows air, the baffle 48 is in a closed state of the ventilation port 32. The centrifugal fan blade 34 rotates under the drive of the third motor 51, draws air from the second air inlet 35, passes through the second air duct 38 and the first air duct 37, and is blocked by the guide plate 41, and then blows air downward from the air outlet 36.

[0045] In the non-intrusive wind mode, the first motor 43 drives the first drive gear 42 to rotate, so that the first drive gear 42 meshes with the rack 44 and drives the guide plate 41 to slide on one side of the slide rail 45, so that the guide plate 41 moves to the junction between the third heating block 62 and the second heating block 59. The air is directed downward from the third heating block 62, the fourth heating block 63, the fifth heating block 64 and the air outlet 36. The fourth heating block 63 and the fifth heating block 64 form the first level of non-intrusive wind heating, and the third heating block 62, the fourth heating block 63 and the fifth heating block 64 form the second level of non-intrusive wind heating. The corresponding third heating block 62, the fourth heating block 63 and the fifth heating block 64 can be activated according to the selected level.

[0046] In the direct-blowing strong wind mode, when the guide plate 41 moves to the edge of the first heating block 58, the third heating block 62, the fourth heating block 63, and the second heating block 59 form the first level of direct-blowing strong wind heating, the fifth heating block 64, the third heating block 62, the fourth heating block 63, and the second heating block 59 form the second level of direct-blowing strong wind heating, and the first heating block 58, the fifth heating block 64, the third heating block 62, the fourth heating block 63, and the second heating block 59 form the third level of direct-blowing strong wind heating, thus realizing multi-level heating in the direct-blowing strong wind mode.

[0047] The air outlet 36 diffuses downward through the vent 23. After the speaker 22 emits sound, the sound is transmitted outward through the vent 23 and the speaker cover 26. The first light ring 27, the second light ring 28 and the lighting lamp 29 serve the function of lighting.

[0048] After the lifting plate 86 is lowered, the first air inlet 84 can be connected to the space at the bottom of the equipment, so that the indoor heater unit 11 can increase the air intake and realize the function of lowering the air intake. Specifically, this is achieved through the structure of motor 85, gear 83 and lifting rack 81. After the gear 83 rotates, it drives the housing 82 to move up and down, which in turn causes the lifting plate 86 to move up and down. After the lifting plate 86 moves to the upper position, it isolates the first air inlet 84 from the space below the equipment, which plays a sealing role. After the lifting plate 86 moves down, it connects the first air inlet 84 with the space below the equipment to increase the air intake of the indoor heater unit 11.

[0049] In ventilation mode, since the first air inlet 84 is connected to the space below the equipment, the air volume entering the indoor heater unit 11 increases, and the first air inlet 84 is a ring-shaped, full-area air intake, which makes the indoor air circulate quickly and improves the ventilation effect.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
