A heater with a linear air outlet and its assembly structure

Abstract

The present invention relates to a heater with a linear air outlet and its assembly structure. Existing heaters have the defect that it is difficult to hide the air inlet and the air outlet, which affects the user experience. The present invention includes a housing, a fan and a heating component. The air inlet and the air outlet of the air duct are both communicated with the indoor space, so that indoor air flows through the air duct under the drive of the fan and forms a heat flow input into the indoor space after flowing through the heating component. The air outlet is strip-shaped and is arranged along the axial direction of the fan outlet. Setting the air outlet as strip-shaped and arranging it along the axis direction of the outlet not only reduces the damage to the integrity of the decorative panel, thereby ensuring the overall aesthetics of the decorative panel, but also effectively increases the distance between the air outlet and the air inlet, effectively avoids the heat flow from being sucked into the air duct again, increases the air circulation range, improves the heating effect, and thus ensures the user experience.

Description

Technical Field

[0001] The present invention relates to the field of integrated ceiling, and particularly to a heater. Background Art

[0002] Currently, heaters for integrated ceilings are becoming more and more popular. Existing heaters include a housing with a built-in air duct, as well as a fan and a heating component connected in series on the housing. The air inlet and outlet of the air duct are both connected to the indoor space, so that indoor air flows through the air duct under the drive of the fan and forms a heat flow input into the indoor space after flowing through the heating component. However, the existing heaters have the following defects: both the air inlet and outlet of the heater are square with a relatively large area. When installed in cooperation with the integrated ceiling, it is necessary to replace the decorative panel with an electrical panel or locally cut holes in the decorative panel, which has the defect of damaging the integrity of the decorative panel and affecting the decorative effect of the integrated ceiling. In addition, the air inlet and outlet are relatively close, resulting in the discharged heat flow being sucked in by the air inlet, thereby reducing the air circulation space, affecting the heating effect and increasing energy consumption, and affecting the use experience. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a heater with a linear air outlet and its assembly structure. The air outlet is set to be strip-shaped, which not only reduces the damage to the integrity of the decorative panel by reducing the width of the air outlet, but also effectively increases the distance between the air outlet and the air inlet, improving the use experience.

[0004] The present invention is achieved in the following way: A heater with a linear air outlet includes a housing with a built-in air duct, as well as a fan and a heating component connected in series on the air duct in sequence. The air inlet and outlet of the air duct are both connected to the indoor space, so that indoor air flows through the air duct under the drive of the fan and forms a heat flow input into the indoor space after flowing through the heating component. The air outlet is strip-shaped and is arranged along the axial direction of the fan outlet. By setting the air outlet to be strip-shaped and arranging it along the axial direction of the outlet, on one hand, by setting the outline of the air outlet to be a narrow strip shape, without reducing the area of the air outlet, the damage to the integrity of the decorative panel is reduced by changing the outline of the air outlet, thereby ensuring the overall aesthetics of the decorative panel. On the other hand, it effectively increases the distance between the air outlet and the air inlet, effectively preventing the heat flow from being sucked into the air duct again, increasing the air circulation range, improving the heating effect, and thus ensuring the use experience.

[0005] Preferably, a buffer air duct extends outward from the side wall of the housing facing the fan outlet, and the air outlet is opened on the bottom surface of the buffer air duct. The air flow discharged from the fan flows into the buffer air duct and is discharged after being transported to a preset area, effectively increasing the distance between the air outlet and the air inlet, and thus expanding the heat transfer range by increasing the air circulation path.

[0006] Preferably, the air outlet is provided with flow guiding plates arranged at equal intervals along the axis of the outlet, so that the air outlet is divided into unit air outlets with different distances from the outlet. The flow guiding plates can change the axial air flow flowing along the buffer air duct into a radial air flow flowing downward, so that the air flow in the buffer air duct is quickly discharged outside, thereby reducing the air resistance by reducing the air pressure in the buffer air duct, and further ensuring the driving efficiency of the fan. The flow guiding plates are arranged at intervals, and the heat flow flows along the buffer air duct and is evenly discharged outside under the action of the flow guiding plates along the way, ensuring the same air volume output of each unit air outlet, and ensuring the uniformity of indoor temperature rise by increasing the heat flow diffusion area.

[0007] Preferably, the periphery of the air outlet extends downward to form an annular air outlet border, and the air outlet border encloses an air outlet channel. The air outlet vertically penetrates through the corresponding decorative panel, so that the heat flow at the air outlet can be discharged into the indoor space after vertically passing through the air outlet channel.

[0008] Preferably, the buffer air duct is linear, and the axis of the buffer air duct is parallel to the axis of the outlet. Since the buffer air duct is arranged along the axis of the outlet, the air resistance of the air flow is effectively reduced, thereby ensuring the heat transfer efficiency by ensuring the air flow velocity, and further ensuring the heating effect of the heater.

[0009] Preferably, the end wall of the buffer air duct far from the housing forms a guiding inclined surface, and the heat flow passing through the buffer air duct flows through the air outlet along the guiding inclined surface and is discharged downward. The heat flow flowing through the buffer air duct is guided to the outside of the air outlet after contacting the guiding inclined surface.

[0010] Preferably, the air inlet is strip-shaped and arranged on the bottom surface of the housing, and the air inlet is parallel to the air outlet. The air inlet is strip-shaped and parallel to the air outlet, effectively reducing the damage to the integrity of the decorative panel and improving the aesthetics.

[0011] Preferably, the vertical projections of the air inlet and the air outlet are arranged in a staggered manner, and the axes of the air inlet and the air outlet are on the same straight line. By increasing the distance between the ends of the air inlet and the air outlet, the air circulation path is increased, thereby improving the indoor temperature rise efficiency.

[0012] Preferably, the inlet of the fan is arranged downward and is vertically corresponding to the air inlet. The inlet and the air inlet are vertically aligned, effectively reducing the air resistance of the air flow, improving the fan efficiency, and further increasing the air flow velocity in the air duct.

[0013] Preferably, the periphery of the air inlet extends downward to form an annular air inlet border, and the air inlet border encloses an air inlet channel. The air inlet vertically penetrates through the corresponding decorative panel, so that the heat flow at the air outlet can be discharged into the indoor space after vertically passing through the air outlet channel.

[0014] An assembly structure of a heater, comprising a keel assembly installed on the ceiling, a decorative panel suspended below the keel assembly, and a heater installed on the keel assembly. The heater includes a main body with an air inlet and an air outlet. Adjacent decorative panels are assembled together with a long strip-shaped through groove reserved between adjacent edges. The air outlet and the air inlet penetrate through the through hole from top to bottom and communicate with the indoor space. With the progress of processing technology, the processing size of the decorative panel can be increased, which not only effectively reduces the splicing seam and improves the overall aesthetics, but also improves the assembly efficiency by reducing the assembly structure. The air inlet and air outlet of the heater are replaced from being exposed through the position of the decorative panel originally to being exposed through the through groove between adjacent decorative panels, without replacing or cutting and opening holes in the decorative panel, which not only ensures the integrity and flatness of the decorative panel and improves the aesthetics, but also facilitates assembly and improves the assembly efficiency.

[0015] Preferably, an adapter plate is sleeved on the air inlet and the air outlet. The adapter plate is inserted into the through groove and blocks the gaps between the air inlet and the inner side wall of the through groove, and between the air outlet and the inner side wall of the through groove. Since the through groove formed between adjacent decorative panels is long strip-shaped and does not match the contours of the air outlet and the air inlet, the adapter plate plays a role in blocking the gaps between the air inlet and the through groove, and between the air outlet and the through groove, improving the aesthetics, and also plays a role in positioning the air inlet and the air outlet.

[0016] Preferably, after being installed in place, the lower port of the air inlet and the lower port of the air outlet are both flush with the bottom surface of the decorative panel, thereby forming a flat decorative surface and improving the aesthetics.

[0017] The beneficial effects of the present invention: The air outlet is set to be long strip-shaped and arranged along the axis of the outlet. By setting the contour of the air outlet to be a narrow long strip shape, without reducing the area of the air outlet, the damage to the integrity of the decorative panel is reduced by changing the contour of the air outlet, thereby ensuring the overall aesthetics of the decorative panel. Also, the distance between the air outlet and the air inlet is effectively increased, effectively avoiding the re-inhalation of the heat flow into the air duct, increasing the air circulation range, improving the heating effect, and thus ensuring the use experience.

[0024] The following further illustrates the substantial features of the present invention in conjunction with the accompanying drawings of the specification and specific embodiments.

[0025] As Figure 1 shown, a heater with a linear air outlet is composed of a housing 1 with an internal air duct, a fan 2 and a heating component 3 connected in series on the air duct in sequence. The air inlet 5 and the air outlet 4 of the air duct are both connected to the indoor space, so that the indoor air flows through the air duct under the drive of the fan 2 and forms a heat flow input into the indoor space after flowing through the heating component 3. The air outlet 4 is in a long strip shape and is arranged along the axial direction of the outlet of the fan 2. Setting the air outlet 4 in a long strip shape and along the axis direction of the outlet can, without reducing the area of the air outlet 4, reduce the damage to the integrity of the decorative panel by changing the contour of the air outlet 4, thereby ensuring the overall aesthetics of the decorative panel, effectively increasing the distance between the air outlet 4 and the air inlet 5, effectively preventing the heat flow from being sucked into the air duct again, increasing the air circulation range, improving the heating effect, and thus ensuring the use experience.

[0026] In actual operation, both the air inlet 5 and the air outlet 4 of the air duct are connected to the indoor space. When in use, as Figure 2 shown, first, the fan 2 starts and extracts indoor air through the air inlet 5. After that, the air flow in the air duct flows through the heating component 3 and is heated to form a heat flow. Finally, the heat flow is discharged to the indoor space through the air outlet 4. The air in the indoor space will realize air flow circulation through the above process, and then improve the indoor temperature by continuously heating the indoor air to achieve the purpose of heating.

[0027] In actual operation, the heater is arranged in cooperation with an integrated ceiling. During installation, the heater and the decorative panel share a triangular keel. The heater is installed above the decorative panel, which can not only use the decorative panel to cover the heater, but also effectively utilize the space above the integrated ceiling. Specifically, a buffer air duct 6 extends outward from the side wall of the housing 1 facing the outlet of the fan 2, and the air outlet 4 is opened on the bottom surface of the buffer air duct 6. The buffer air duct 6 is arranged on the side of the housing 1, so that the buffer air duct 6 is hidden above the decorative panel, effectively reducing the exposed area of the heater 2, thereby reducing the damage to the integrity of the decorative panel and improving the aesthetics.

[0028] In actual operation, the buffer air duct 6 is linear, and the axis of the buffer air duct 6 is parallel to the axis of the outlet. In a preferred embodiment, the axis of the buffer air duct 6 coincides with the axis of the outlet. The air flow formed by the operation of the fan 2 is discharged into the buffer air duct 6 through the outlet. The heat flow rate at the air outlet 4 is related to the air resistance in the buffer air duct 6. The buffer air duct is set to be linear to reduce its air resistance, thereby ensuring that the air flow can pass through the air duct at a relatively high flow rate, and then improving the heat transfer efficiency and the temperature rise speed of the indoor space.

[0029] Specifically, the heat flow output through the outlet will flow along the axis of the buffer air duct. The flow guide plates 7 arranged along the way will split the heat flow, which can not only ensure the same air outlet efficiency of each unit air outlet and ensure that the heat flow is evenly delivered to the area corresponding to the air outlet 4, but also reduce the air pressure in the buffer air duct 6 by exhausting the heat flow, thereby reducing the air resistance of the heat flow entering the buffer air duct 6 and increasing the air flow velocity.

[0030] In actual operation, flow guide plates 7 are arranged at equal distances along the axis of the outlet in the air outlet 4 (as Figure 3 shown), so that the air outlet 4 is divided into unit air outlets with different distances from the outlet. When the flow guide plates 7 in the air outlet 4 are vertically arranged, the flow direction of the heat flow can be changed from flowing along the axis of the buffer air duct 6 to flowing downward. In a preferred embodiment, the flow guide plates 7 tend to be vertically arranged, the top ends of the flow guide plates 7 are close to the housing 1, and the bottom ends of the flow guide plates 7 are far from the housing 1, which not only ensures that the heat flow blows downward and away from the housing 1, but also effectively improves the efficiency of intercepting the heat flow in the buffer air duct 6. By improving the heat flow exhaust efficiency, the pressure in the buffer air duct 6 is reduced, and then the heat flow rate is increased.

[0031] In actual operation, the heating component 3 adopts an electric heating method, which effectively improves the heating efficiency. The heating component 3 is arranged at the outlet of the fan 2, which not only reduces the heat loss by shortening the distance between the heating component 3 and the air outlet 4, but also effectively prevents the fan 2 from being damaged due to heat accumulation.

[0032] In actual operation, the periphery of the air outlet 4 extends downward to form an annular air outlet border 8, and the air outlet border 8 encloses an outflow channel. The periphery of the air inlet 5 extends downward to form an annular air inlet border 9, and the air inlet border 9 encloses an inflow channel. By providing the outflow channel and the inflow channel to pass through the decorative panel, after being installed in place, the lower ports of the outflow channel and the inflow channel are flush with the bottom surface of the decorative panel, which not only ensures the flow efficiency but also ensures the aesthetics.

[0033] In actual operation, a guiding inclined surface 10 is formed on the end wall of the buffer air duct 6 away from the housing 1. The heat flow passing through the buffer air duct 6 flows along the guiding inclined surface 10 through the air outlet 4 and is discharged downward and outward. The top edge of the guiding inclined surface 10 is arranged close to the housing 1, and the bottom edge is arranged away from the housing 1, ensuring that the heat flow penetrating the buffer air duct 6 can flow downward out of the air outlet 4 under the action of the guiding inclined surface 10 and providing a buffer space for the subsequent heat flow.

[0034] In actual operation, the air inlet 5 is strip-shaped and arranged on the bottom surface of the housing 1, and the air inlet 5 and the air outlet 4 are arranged parallel to each other. The inlet of the fan 2 is arranged downward and is vertically corresponding to the air inlet 5. The vertical projections of the air inlet 5 and the air outlet 4 are arranged in a staggered manner, and the axes of the air inlet 5 and the air outlet 4 are located on the same straight line, which is convenient for cooperation with the decorative panel or its edge, and effectively increases the distance between the air outlet 4 and the air inlet 5, and improves the range of air flow circulation.

[0035] In actual operation, the radial cross-sectional profile of the buffer air duct is circular (as Figure 4 shown), which is convenient for the heat flow to converge along the inner side wall of the buffer air duct to the air outlet at the bottom.

[0036] In actual operation, the assembly structure for the warm air heater includes a keel assembly installed on the ceiling, a decorative panel 11 suspended below the keel assembly, and a heater installed on the keel assembly. The heater includes a main body with an air inlet 5 and an air outlet 4. Adjacent decorative panels 11 are assembled and a long strip-shaped through groove is reserved between adjacent edges. The air outlet 4 and the air inlet 5 penetrate the through hole from top to bottom and communicate with the indoor space (as Figure 5 shown). Specifically, first, the keel assembly is installed below the ceiling; then, the warm air heater is installed on the keel assembly so that the air inlet 5 and the air outlet 4 extend downward and are open; then, the decorative panel 11 is suspended below the keel assembly so that the adjacent edges of the decorative panel 11 are assembled to form a through groove wrapping the air inlet 5 and the air outlet 4; finally, the connecting plate 12 is sleeved on the air inlet 5 and the air outlet 4, effectively preventing the gap between the inner side wall of the through groove and the air inlet 5 and the air outlet 4.

[0037] In actual operation, a connecting plate 12 is sleeved on the air inlet 5 and the air outlet 4. The connecting plate 12 is inserted into the through groove and seals the gaps between the air inlet 5 and the inner side wall of the through groove and between the air outlet 4 and the inner side wall of the through groove. After being installed in place, the lower ports of the air inlet 5 and the air outlet 4 are flush with the bottom surface of the decorative panel 11, thereby forming a flat decorative surface and improving the aesthetics. The connecting plate is provided with through holes for the vertical penetration of the air inlet surround and the air outlet surround. After being installed in place, the outer peripheral edge of the connecting plate is smoothly connected with the edges of adjacent decorative plates, and the inner side walls of the through holes are respectively attached to the outer side walls of the corresponding air inlet surround and air outlet surround, improving the aesthetics by reducing the fitting gap.
