Description

Technical Field

[0001] The utility model relates to the field of fresh air ventilation and heating appliances, in particular to an extremely narrow air inlet line multifunctional heater. Background Art

[0002] In the field of fresh air ventilation and heating, whether it is a bathroom heater, kitchen heater, heater or air conditioner, the airflow from the air inlet on the panel will directly collide with the fan inlet of the equipment when entering the equipment, thus generating huge turbulent noise, and the noise will become louder and louder with factors such as the fan power and air intake volume.

[0003] In the design of extremely narrow linear air inlets, the diameter of the air inlet of traditional products is too large. If the centrifugal fan heater is forcibly matched with the linear panel, the fan air inlet has too small an overlapping area with the panel linear air inlet, and most of the intake air cannot be drawn from the linear panel. The interlayer above the ceiling needs to be used to supplement the air flow, which leads to the problem of air intake attenuation during actual installation. The air hygiene above the ceiling is not guaranteed, and bacteria and dust are easily generated; and the supplementary air flow is not the air flow that has been heated indoors, which makes the circulating heating efficiency low and the thermal energy utilization is reduced. It is impossible to achieve 100% internal circulation heating of indoor air, and the heating efficiency is low. Therefore, the utility model came into being. Utility Model Content

[0004] In view of the above situation, the primary problem that the utility model solves is that in the traditional extremely narrow linear air inlet design, since the overlapping area between the fan air inlet and the panel linear air inlet is too small, most of the intake air flow cannot be absorbed from the linear panel, and the mezzanine above the ceiling is required to supplement the air flow.

[0005] To this end, the utility model provides an extremely narrow air inlet line multifunctional heater, which is characterized by comprising:

[0006] A chassis, wherein the panel of the chassis is linearly provided with an air inlet and an air outlet, and the chassis is also provided with a ventilation port; an air inlet cabin, a fan cabin and an air outlet cabin are provided inside the chassis, the air inlet cabin is located on one side of the fan cabin and is connected to the fan cabin, the air outlet cabin is located on the other side of the fan cabin, the air inlet is connected to the air inlet cabin, and the air outlet and the ventilation port are connected to the air outlet cabin;

[0007] A fan, wherein the fan is arranged in the fan compartment, and the air inlet compartment is located at one side of the air inlet end of the fan and is connected to the air inlet end;

[0011] Preferably, the chassis includes a left box body and a right box body, and the joint between the left box body and the right box body is in the same direction as the air inlet and the air outlet.

[0012] Preferably, an air inlet channel is formed between the air inlet end of the fan and the inner wall of the chassis, and the air inlet cabin is connected to the air inlet end of the fan through the air inlet channel; the air inlet direction of the air inlet end of the fan is perpendicular to the air inlet direction of the air inlet.

[0013] Preferably, the air inlet is a multi-section air inlet; each section of the air inlet is connected to the air inlet end of the fan through an air guiding channel, and the air guiding channel is arranged in the air inlet cabin.

[0014] Preferably, the wind guide channel includes a wind guide plate, the wind guide plate has a wind guide surface, one end of the wind guide surface is introduced from the air inlet, and the other end is guided out to the air inlet end of the fan.

[0015] Preferably, the wind guiding surface is a concave arc surface.

[0016] Preferably, a sound-absorbing sponge is provided on the back side of the air guide plate relative to the air guide surface.

[0017] Preferably, a waterproof cabin box is further provided in the chassis, the waterproof cabin box comprises a waterproof cabin body and a hatch cover, the waterproof cabin body is provided in the chassis and the hatch position corresponds to the panel, the hatch cover is detachably installed on the hatch; at least a control component is provided in the waterproof cabin body.

[0019] The present application arranges the air inlet compartment on one side of the fan compartment, and the air inlet and the air outlet are located on the panel, so that the air inlet of the fan compartment and the panel can be perfectly matched, and there is no need for a mezzanine above the ceiling to supplement the air intake, thereby achieving 100% internal circulation heating of the indoor air, with higher heating efficiency and faster heating.

[0020] The internal air guide channel is designed to guide the air evenly, greatly reducing the noise at the air inlet.

[0021] It breaks the pain point of disassembly and assembly of linear appliances. Since the air inlet and the air inlet end of the fan do not overlap, the narrowest body design can reach 100mm. The installation and disassembly of the body does not require the removal or destruction of the ceiling, which is convenient and quick to reduce the installation and rework workload. In the application, both honeycomb large panels and gypsum board ceilings are suitable for installation, and there is no need to reserve inspection openings.

[0037] Please refer to Figure 1 to Figure 6This embodiment describes a multifunctional heater with an extremely narrow air inlet line, and its structure includes a chassis 1, a fan 3, a heating component and a conversion valve component 4.

In this solution, the air inlet compartment 120 is arranged on one side of the fan compartment 30, and the air inlet 12 and the air outlet 13 are located on the panel 11, so that the fan compartment 30 and the air inlet 12 of the panel 11 can be perfectly matched, and there is no need for a mezzanine above the ceiling to supplement the air intake, thereby achieving 100% internal circulation heating of the indoor air, with higher heating efficiency and faster heating.

[0038] See also Figure 1 , Figure 2 and Figure 3 As the structural carrier of the whole machine, this embodiment continues the linear structural design; in order to achieve a linear minimalist appearance, the chassis 1 in this embodiment is in a long strip shape, and the air inlet 12 and the air outlet 13 are linear air outlets 13, which are arranged on the panel 11 of the chassis 1.

[0039] See also Figure 1 and Figure 2 Structurally, the chassis 1 may include a box body and a panel 11, which are integrally formed. Alternatively, the chassis 1 may include a left box body 101 and a right box body 102, and the seam between the left box body 101 and the right box body 102 is in the same direction as the air inlet 12 and the air outlet 13. The seam may be connected by gluing or ultrasonic bonding.

[0040] As the core design of this embodiment, please combine Figure 3 and Figure 6 , the air inlet 12 and the air inlet end of the fan 3 do not overlap in structure, thereby hiding the fan 3 and increasing the air intake. Specifically, an air inlet channel 300 is formed between the air inlet end of the fan 3 and the inner wall of the chassis 1, and the air inlet cabin 120 is connected to the air inlet end of the fan 3 through the air inlet channel 300. From the spatial position, the air inlet direction of the air inlet end of the fan 3 is perpendicular to the air inlet direction of the air inlet 12, so that the positions of the fan 3 and the air inlet 12 are misaligned. Therefore, compared with the traditional solution of overlapping the positions of the fan 3 and the air inlet 12, the air intake of this embodiment can be greatly improved through the air volume introduction of the air inlet 12.

[0041] Further, please combine Figure 3 and Figure 4 , the air inlet 12 is a multi-section air inlet 12. Each section of the air inlet 12 is connected to the air inlet end of the fan 3 through an air guide channel 1200, and the air guide channel 1200 is arranged in the air inlet cabin 120. Specifically, the air inlet 12 is divided into two sections and arranged in a linear shape. The air guide channel 1200 includes an air guide plate 121, and the air guide plate 121 has an air guide surface, one end of which is introduced from the air inlet 12, and the other end is exported to the air inlet end of the fan 3. Thereby, all the air from the air inlet 12 is introduced into the fan 3, and the air inlet 12 and the air outlet 13 are in the same direction, so that the heated air in the room is sucked in by the fan 3 and circulated again, achieving 100% heat energy recycling.

[0042] Furthermore, in order to reduce wind noise and avoid the collision between the wind flow and the wind guide plate 121, the wind guide surface of the wind guide plate 121 is an inwardly concave arc surface, and the wind guide channel 1200 formed by it is also a curved channel. More preferably, the wind guide plate 121 is provided with a sound-absorbing sponge (not shown) on the back side of the wind guide surface, which does not affect the wind flow and can also play a role in sound absorption.

[0043] Please combine Figure 4 and Figure 5 , in order to prevent water from entering the electrical components, and also to facilitate maintenance and wiring. A waterproof cabin box 2 is also provided in the chassis 1, and the waterproof cabin box 2 includes a waterproof cabin body 22 and a hatch cover 21. The waterproof cabin body 22 is arranged in the chassis 1 and the hatch position corresponds to the panel 11, and the hatch cover 21 is detachably installed on the hatch. Further, at least a control component is provided in the waterproof cabin body 22. Furthermore, the control component includes at least a control main board, and a card slot for inserting the control main board is provided in the waterproof cabin body 22, and a limit buckle (not shown) is provided at the end of the card slot to prevent the control main board from falling off due to gravity.

[0044] Specifically, when the whole machine is installed, the hatch faces the room; after the hatch cover 21 is opened, the buckle limit control mainboard slides down due to gravity, and a wiring port can be set in the waterproof cabin 22 or on the hatch cover 21 to facilitate the connection of lighting panels or other electrical, control and other components.

[0045] Please combine Figure 4 and Figure 5In order to achieve the functions of ventilation and heating, the air outlet cabin of this embodiment is divided into two air outlet cabin bodies by the partition 15, and the two are converted by the conversion valve assembly 4. The first air outlet cabin body 140 is connected to the air outlet end of the fan 3 and the ventilation port 14; the second air outlet cabin body 130 is connected to the air outlet 13 and the first air outlet cabin body 140 by setting an opening on the partition 15. The conversion valve assembly 4 is arranged at the opening, and its structure includes a valve 41, a conversion motor 42, a driving gear 43 and a base 44. Specifically, the valve 41 is installed on the base 44, and the base 44 is pivoted to the chassis 1 through a rotating shaft so that the opening of the partition 15 can be opened and closed, and the driving gear 43 is installed on the motor shaft of the conversion motor 42, and a tooth segment 441 is provided on the base 44; the tooth segment 441 of the base 44 is an arc-shaped tooth segment 441 with the pivot point as the center of the circle. The arc-shaped tooth segment 441 meshes with the driving gear 43, and then the valve 41 can be driven to open / close by the conversion motor 42. Therefore, whether the first air outlet cabin 140 is connected to the second air outlet cabin 130 can be controlled according to the opening and closing state; the flow rate between the first air outlet cabin 140 and the second air outlet cabin 130 can be controlled according to the opening and closing degree, thereby controlling the air volume and realizing different ventilation and heating combination functions.

[0046] Furthermore, the heating component is a PTC heater 4 provided on the air outlet 13 to realize instant warm air, and the air outlet 13 realizes air volume control through a blade, which is a prior art and will not be elaborated here.

[0047] The beneficial effects of this embodiment are:

[0048] The present application arranges the air inlet compartment 120 on one side of the fan compartment 30, and the air inlet 12 and the air outlet 13 are located on the panel 11, so that the fan compartment 30 and the air inlet 12 of the panel 11 can be perfectly matched, and there is no need for a mezzanine above the ceiling to supplement the air intake, thereby achieving 100% internal circulation heating of the indoor air, with higher heating efficiency and faster heating.

[0049] The internal air guide channel 1200 has a flow-guiding design, and the airflow is uniform, which greatly reduces the noise of the air inlet 12.

[0050] It breaks the pain point of disassembly and assembly of linear appliances. Since the air inlet 12 and the air inlet end of the fan 3 do not overlap, the narrowest body design can reach 100mm. The body installation and disassembly do not require the removal or destruction of the ceiling, which is convenient and quick to reduce the installation and rework workload. In the application, both honeycomb large panels and gypsum board ceilings are suitable for installation, and there is no need to reserve inspection openings.

[0051] The chassis 1 has a built-in waterproof cabin box 2, and the main control PCB board and the panel 11 are perfectly matched. There is no need to disassemble the fuselage, and the main control PCB board can be repaired through the cabin cover 21. At the same time, low-voltage lighting and panel 11 control wiring can be directly output.

[0052] The chassis 1 is assembled from left to right, which is simple and convenient. The joints and the air inlet 12 and the air outlet 13 are connected, making the overall body present a minimalist style without losing the visual high-end texture of the product; the hidden air inlet 12 does not overlap with the fan 3, making the fan wheel invisible and improving the appearance of the host. The air inlet 12 and the air outlet 13 are gathered at the center line of the body, so that the design of the panel 11 can continue to use the linear design ID, or a symmetrical design can be made.
