[0005] As preferred, the peripheral profile of the wind guide grille matches the inner edge profile of the air outlet, so that the airflow in the air duct flows through the unit passageway and converges into linear wind beams conveying in the preset direction. The wind guide grille covers the air outlet, ensuring that the airflow flowing through the air outlet can be separated, diverted and guided by the wind guide grille and form linear wind beams, effectively reducing turbulence and maintaining the kinetic energy of the airflow.

The axes of the unit passageways are linear, effectively improving the diversion and guiding effect, ensuring that the linear wind beams flow and convey in the same direction.

[0007] As preferred, the circulating fan is a high-speed ducted fan. The high-speed ducted fan has the characteristics of small size and high output airflow speed, which effectively reduces the requirement for the space inside the shell, thereby reducing the size of the shell, facilitating disassembly and assembly, and increasing the delivery distance by increasing the airflow speed.

[0014] As preferred, the vertical projection of the shell is in a strip shape, so that the shell can be vertically inserted, pulled out, disassembled through the gap between adjacent decorative plates.

[0015] As preferred, the shell is provided with independent circulating fans and air ducts on both sides, respectively, and a return air inlet is arranged in the middle of the bottom surface of the shell and is in communication with the inlets of the circulating fans.

[0024] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 and 2 The heater shown comprises a housing 1, inside which a circulating fan 2 and an air duct 3 are installed. The air inlet of the air duct 3 is connected to the outlet of the circulating fan 2, and the air outlet 4 is exposed on the surface of the housing 1 and communicates with the indoor space. Several unit channels 6 with the same orientation are formed within the air outlet 4 by means of a guide grille 5. The airflow within the air duct 3 is split into multiple linear air jets through the unit channels 6 to increase the airflow delivery distance. The guide grille 5 at the air outlet 4 splits the airflow from the air duct 3 into multiple linear air jets with the same flow direction. Adjacent air jets flow in the same direction and do not interfere with each other, effectively reducing energy loss. This increases the delivery distance by increasing the airflow velocity, thus improving the user experience.

[0026] In actual operation, the peripheral contour of the air guide grille 5 matches the inner contour of the air outlet 4, so that the airflow in the air duct 3 flows through the unit channel 6 and converges into a linear air duct that is transported in a preset direction. The circulating fan 2 draws indoor air and transports it to the air duct 3. The air duct 3 guides the airflow through the heating module 9 to form hot air. The hot air passes through the air guide grille 5 along the axial direction of the air outlet 4 and is then split into several linear air ducts with the same flow direction. The axes of the unit channels 6 are set parallel to each other. The linear air ducts flow along the axial direction of the unit channels 6 to reduce interference between adjacent linear air ducts, ensure that there is no loss of kinetic energy due to the interlacing of adjacent linear air ducts, ensure that each linear air duct can flow independently and increase the delivery distance, effectively improving the user experience.

[0027] In actual operation, the air outlet 4 and air inlet of the air duct 3 are both circular, and the cross-sectional profile of each section of the air duct 3 remains approximately the same, ensuring that the airflow will not be squeezed due to excessive changes in the cross-sectional profile of the air duct 3. By reducing wind resistance, the airflow energy is effectively maintained, and by maintaining the airflow velocity, the delivery distance is increased. This ensures that hot air is delivered to a larger area, ensures that the temperature of each area in the room is balanced, and can also concentrate the delivery of hot air in a specific direction, so as to dry hair and clothes.

[0028] In actual operation, the air guide grille 5 includes a circular guide plate 7 with its diameter gradually increasing from the inside to the outside, and a radial guide plate 8 (e.g., along the air outlet 4) arranged radially. Figure 3 As shown, circular guide plates 7 and radial guide plates 8 are integrally staggered and enclosed to form the unit channel 6. Adjacent circular guide plates 7 are concentrically and equidistantly arranged, and the radial guide plates 8 are distributed at equal angles around the air outlet 4. This ensures that the airflow in each area of ​​the cross-section of the air duct 3 can be effectively converged and integrated to form a linear air bundle with a unified flow direction. It also ensures that the cross-sectional area of ​​each unit channel 6 is approximately the same, thereby ensuring that each linear air bundle has a balanced flow rate and kinetic energy, thus obtaining an approximate conveying distance and preventing the linear air bundle from diffusing and disappearing during the conveying process.

[0029] In actual operation, the diameter of the middle section of the air duct 3 is smaller than the diameter of the air outlet 4 and the air inlet. A heating module 9 is installed within this middle section. Airflow from the air inlet converges along the narrowed middle section to the heating module 9, and after passing through the heating module 9, it is discharged through the expanded air outlet 4. The small diameter of the middle section of the air duct 3, completely sealed by the heating module 9, ensures that all airflow through the air duct 3 must pass through the heating module 9. This protects the heating module 9, facilitates timely heat dissipation, and ensures uniform hot air temperature. The air inlet collects airflow from the outlet of the circulating fan 2 and converges it towards the heating module 9 through the narrowed structure. The airflow passing through the heating module 9 is diffused to various areas of the air outlet 4 through the expanded diameter, thereby ensuring that each unit channel 6 receives a balanced airflow and that each linear airflow has the kinetic energy and airflow to deliver to a distant area.

[0030] In actual operation, the air duct 3 is L-shaped, including a vertical part forming the air outlet 4 and a horizontal part forming the middle section of the stroke and the air inlet. The air outlet 4 is opened on the bottom surface of the housing 1. The bottom of the housing 1 has a return air inlet 11. The inlet of the circulating fan 2 is connected to the return air inlet 11, and the outlet is connected to the air inlet of the air duct 3. This forms a chamfered path in which the return air inlet 11 and the air outlet 4 are opened in the same direction, ensuring that the indoor air flows through the chamfered path and then returns through the air outlet 4, thus forming a circulation path.

[0031] In actual operation, the outlet and inlet of the circulating fan 2 are coaxially arranged. A vortex-shaped air guide vane 10 is provided at the outlet. The airflow output by the circulating fan 2 forms a vortex that is directed towards the heating module 9 through the air guide vane 10, ensuring that all areas of the heating module 9 receive airflow evenly. The airflow output by the circulating fan 2 forms a spiral vortex after passing through the vortex-shaped air guide vane 10, allowing the airflow to pass through all areas of the windward side of the heating module 9, ensuring that each area of ​​the heating module 9 receives a large amount of airflow, which is beneficial for heat transfer.

[0032] In actual operation, the vertical projection of the housing 1 is elongated, allowing for vertical insertion and removal through the gaps between adjacent decorative panels. The vertical projections of the housing 1 all fall within the bottom surface area, and the bottom contour of the housing 1 matches the contour of the gaps between adjacent decorative panels. This ensures that the housing 1 can be directly inserted and removed vertically through the gaps without removing the decorative panels, while also ensuring that the bottom surface of the housing 1 completely seals the gaps, improving aesthetics.

[0033] In actual operation, the two sides of the housing 1 are respectively provided with independent circulating fans 2 and air ducts 3. The bottom surface of the housing 1 is provided with a return air port 11 connected to the inlet of each circulating fan 2. The circulating fan 2 draws the airflow from the return air port 11 and returns it to the indoor space through the corresponding air outlet 4. There are two air ducts 3, which are respectively located on both sides of the housing 1, so that both sides of the bottom surface of the housing 1 are provided with downward-facing exposed air outlets 4 (e.g., Figure 5 As shown in the figure, the indoor heating efficiency is improved by increasing the number of circulating fans 2, heating modules 9 and air ducts 3.

[0034] In actual operation, the return air vent 11 is equipped with a ventilation fan 12 (such as...). Figure 4 As shown, the outlet of the ventilation fan 12 is connected to the outdoor space. The inlet of the ventilation fan 12 draws air from the return air vent 11 and discharges it to the outdoor space, thereby enabling air exchange between the indoor and outdoor spaces and effectively improving indoor air quality.

[0035] In actual operation, both the circulating fan 2 and the ventilation fan 12 are high-speed ducted fans, which have a small size, making it easy to install inside the casing 1, and a large output air volume, thus meeting the requirements for long-distance airflow transportation.
