Description

Technical Field

[0001] This utility model relates to the field of integrated ceiling systems, specifically to a heater. Background Technology

[0002] Existing heaters include a main unit and a face shield located below the main unit. To improve the diffusion efficiency of hot air, air outlets are provided on all four sides of the face shield. The main unit includes a housing and a fan and air guide plates housed within the housing. The air guide plates are multiple pieces stacked to form air ducts connecting the fan and each air outlet. The air ducts are arranged one-to-one with the air outlets, resulting in a complex air guide plate structure. This increases the difficulty of production and assembly, raises production and assembly costs, and negatively impacts the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a heater with a wind-guiding cover. The cover is equipped with an air duct, which guides airflow to multiple air outlets, effectively simplifying the air duct structure, facilitating processing and assembly, and improving the user experience.

[0004] This utility model is achieved through the following method: a heater with a guide plate, including a main unit and a faceplate disposed below the main unit. The faceplate has an air outlet on its edge. The main unit includes a housing, a fan disposed within the housing, and a cover plate covering the bottom of the housing. The cover plate has an air duct, and the cover plate covers the bottom of the housing. The inlet of the air duct is tangentially arranged along the fan, and the outlet of the air duct is L-shaped and arranged along the edge of the cover plate, so that the airflow generated by the fan is diverted through the air duct to the edge of the main unit and diffused outward through the corresponding air outlet. By providing a cover plate with an air duct, the air duct receives airflow from the fan through its inlet and delivers airflow to multiple air outlets located on adjacent edges of the faceplate through its L-shaped outlet. This allows a single air duct to deliver airflow to multiple air outlets, effectively simplifying the air duct structure, facilitating processing and assembly, and improving the user experience.

[0005] Preferably, the cover plate has an irregularly shaped channel forming the air duct at its edge. The top of the channel has a horizontally opening upper cavity tangentially connected to the fan, and the bottom has a lower cavity for mounting the heating element. The airflow generated by the fan flows through the heating element under the guidance of the channel and forms hot air that is delivered outwards. The irregularly shaped channel forms an air duct connecting the fan and the air outlet. The two ends of the channel are exposed, and the middle is non-linear, facilitating airflow and guiding its direction to ensure it is delivered in a predetermined direction. The upper cavity at the top of the channel has its opening horizontally tangentially to the fan, effectively reducing air resistance as the airflow travels from the fan to the air duct. The lower cavity's opening is located at the edge of the cover plate and faces downwards, ensuring the airflow is delivered downwards to the air outlets on the mask, thus reducing energy loss.

[0006] Preferably, the lower cavity is L-shaped, comprising a long straight section and a short straight section that are interconnected, and the heating components are in two sets, respectively disposed on the long straight section and the short straight section. The L-shaped lower cavity can be arranged along two adjacent edges of the cover plate, allowing a single air duct to simultaneously supply air to multiple air outlets located on adjacent edges of the mask, effectively simplifying the air duct structure and thereby increasing airflow by reducing wind resistance.

[0007] Preferably, the long straight section extends upward to form a shaped channel in the middle section. This middle section has a windward inclined surface. The horizontal airflow from the fan turns downward through the windward inclined surface and is discharged outward through the lower channel cavity. By utilizing the length of the long straight section to reduce the angle between the windward inclined surface and the horizontal plane, the kinetic energy loss of the airflow during the turn is effectively reduced, the airflow volume is increased, and the airflow is effectively turned, thus ensuring that the airflow can change from horizontal to vertical flow and be delivered outward through the corresponding air outlet.

[0008] Preferably, the top edge of the windward inclined surface is flush with the top edge of the upper cavity, and the bottom edge of the windward inclined surface extends obliquely downward and connects with the lower cavity. By increasing the length of the windward inclined surface, the deflection effect on the airflow is improved, which not only effectively reduces turbulence but also ensures that each section of the lower cavity receives a balanced airflow.

[0009] Preferably, the heating element includes a bracket inserted into a corresponding section of the lower cavity, a PTC heating element disposed within the bracket, and an air guide cover covering the bracket. The bracket is installed in the lower cavity and has a channel for airflow. The PTC heating element is installed within the channel, ensuring that all airflow passing through the bracket is heated by the PTC heating element and forms hot air. The hot air is guided to the corresponding air outlet by the air guide cover installed on the bracket's back side facing the cover plate, ensuring that the hot air is delivered to the preset area.

[0010] Preferably, a corner plate is provided at the junction of the long straight section and the short straight section. The corner plate seals the gap between the heating elements in the lower cavity, so that the cavity opening of the lower cavity is divided into independent air vents located at the long and short straight sections. The corner plate covers the corner of the lower cavity and forms a sealed air passage. The long straight section receives the airflow from the inlet and transfers it to the short straight section through the air passage, ensuring that the heating elements installed on the long and short straight sections can receive an equal amount of hot air and form hot air delivered to the corresponding air outlet.

[0011] Preferably, the vertical projection of the cover and the cover plate are both rectangular, there are two fans placed on both sides of the main unit, and there are two air ducts placed along the periphery of the cover plate. By setting two fans to supply air to the four air outlets located on the edge of the mask, it is possible to ensure that each air outlet has a balanced air volume and effectively increase the air volume to meet the usage requirements.

[0012] Preferably, the fan includes fan blades and a volute that encloses the fan blades and communicates with the air duct. The volute is formed by a cover plate disposed along the periphery of the fan inside the volute and covering the volute with the cover plate. The cover plate and volute are integrally formed, with the cover plate covering the cover plate to form the volute that encloses the fan blades. This design facilitates manufacturing and effectively guides airflow towards the air duct.

[0013] Preferably, the vertical projections of the air duct and the fan are staggered. This staggered arrangement of the air duct and fan at the same height effectively utilizes the space between the side wall of the casing and the surrounding panel, and also facilitates airflow by reducing the distance between the air duct and the volute.

[0014] The beneficial effects of this utility model are as follows: The cover plate with air duct is provided. The air duct receives airflow from the fan through the inlet and delivers airflow to multiple air outlets located on the adjacent edges of the mask through the L-shaped outlet. This allows a single air duct to deliver airflow to multiple air outlets, effectively simplifying the air duct structure, facilitating processing and assembly, and improving the user experience.

[0019] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 and 2 The heater shown is a type of heater with a guide plate, consisting of a main unit 1 and a face shield located below the main unit 1. The face shield has an air outlet on its edge. The main unit 1 includes a housing 2, a fan installed inside the housing 2, and a cover plate 3 covering the bottom of the housing 2. The cover plate 3 has an air duct and covers the bottom of the housing 2. The inlet of the air duct is tangential to the fan, and the outlet of the air duct is L-shaped and located along the edge of the cover plate 3, so that the airflow generated by the fan is diverted through the air duct to the edge of the main unit 1 and diffused outward through the corresponding air outlet.

[0021] In actual operation, the mask is rectangular, with air outlets located at the center of each edge, resulting in two long air outlets symmetrically positioned on the long edge and two short air outlets symmetrically positioned on the short edge. The main unit 1 contains a fan and an air duct. The air duct is mounted on the cover plate 3. The inlet of the air duct connects to the fan's volute, and the outlet is L-shaped, allowing simultaneous connection to adjacent short and long air outlets on the mask. This shared air duct simplifies the structure of the main unit 1, facilitating assembly and use, and effectively reducing processing costs.

[0022] In actual operation, the edge of the cover plate 3 is provided with an irregularly shaped channel 4 forming the air duct. The top of the irregularly shaped channel 4 is provided with an upper cavity that is horizontally opened and tangentially connected to the fan. The bottom of the irregularly shaped channel 4 is provided with a lower cavity for installing the heating element. The airflow generated by the fan flows through the heating element under the guidance of the irregularly shaped channel 4 and forms hot air that is delivered outward. The irregularly shaped channel 4 includes an upper cavity that communicates with the fan and a lower cavity that communicates with the air outlet.

[0023] In actual operation, the long straight section 5 extends upward to form the middle section of the irregularly shaped through-slot 4. This middle section has a windward inclined surface 7. The horizontal airflow from the fan turns downward through the windward inclined surface 7 and is discharged through the lower slot cavity. The top edge of the windward inclined surface 7 is flush with the top edge of the upper slot cavity, and the bottom edge of the windward inclined surface 7 extends obliquely downward and connects with the lower slot cavity. The upper slot cavity is a right-angled triangle, including a vertical side forming a cavity opening communicating with the volute, a horizontal side communicating with the lower slot cavity, and an inclined side forming the windward inclined surface 7 (e.g., ...). Figure 3 (As shown).

[0024] In actual operation, the lower cavity is L-shaped, including a long straight section 5 and a short straight section 6 that are perpendicular to each other and connected. The top wall of the long straight section 5 extends upward to form the upper cavity. The bottom edge of the windward inclined surface 7 is located on the side of the top wall of the long straight section 5 near the short straight section 6, which is used to transform the horizontal airflow from the vertical side of the upper cavity into a downward-directed vertical airflow, thereby ensuring that the airflow can diffuse along the lower cavity to each air outlet.

[0025] In actual operation, the heating components are in two sets, respectively mounted on the long straight section 5 and the short straight section 6. Each heating component includes a bracket 8 inserted into the corresponding section of the lower cavity, a PTC heating element 9 housed within the bracket 8, and an air guide shroud 10 covering the bracket 8. The length of the heating component matches the length of the corresponding section of the lower cavity; increasing the length of the heating component improves airflow efficiency, thereby increasing the hot air volume. The top of the bracket 8 is inserted into and fixed to the corresponding section of the lower cavity. The PTC heating element is inserted into the lower port of the bracket 8, and the top of the air guide shroud 10 is fitted onto the lower port of the bracket 8. The airflow from the lower cavity passes sequentially through the bracket 8, the PTC heating element, and the air guide shroud 10, forming hot air which is then delivered outward through the corresponding air outlet.

[0026] In actual operation, a corner plate 11 is provided at the junction of the long straight section 5 and the short straight section 6. The corner plate 11 blocks the gap between the heating elements in the lower cavity, so that the cavity opening of the lower cavity is divided into independent air vents located at the long straight section 5 and the short straight section 6. The corner plate 11 is set between adjacent air guide hoods 10, which serves to block the corners of the lower cavity, ensuring that the airflow can pass through the heating elements to form hot air, and also ensures that the airflow received by the long straight section 5 can be effectively delivered to the short straight section 6, thereby ensuring uniform airflow at the long and short air vents. The air vents are exposed through the long and short edges of the hood, respectively, forming the long and short air vents.

[0027] In actual operation, the vertical projections of the casing 2 and the cover plate 3 are both rectangular. There are two fans, one on each side of the main unit 1, and two air ducts, one along the perimeter of the cover plate 3. Each fan can simultaneously deliver hot air to adjacent long and short air vents through its corresponding single air duct. The vertical projections of the air ducts and fans are staggered. After installation, the air ducts are all located in the gaps between the fans and the side walls of the casing 2, effectively improving the space utilization efficiency inside the casing 2, effectively reducing the size of the heater, and facilitating transportation, assembly, and use.

[0028] In actual operation, the fan includes fan blades 12 and a volute that encloses the fan blades 12 and communicates with the air duct. The housing 2 contains a surrounding plate 13 arranged along the periphery of the fan. A cover plate 3 covers the housing 2 and, together with the surrounding plate 13, forms the volute. The volute is formed by the top wall of the housing 2, the surrounding plate 13, and the cover plate 3. The side of the volute is connected to the air duct inlet to ensure smooth airflow.
