Description

Technical Field

[0001] This invention relates to the field of electric heating technology, and more specifically to a high-efficiency electric heater that uses an infrared heating device for heating. Background Technology

[0002] The walls of buildings in northern my country are much thicker, more than twice as thick as those in central China. Therefore, to achieve the same heating effect in the north, buildings in central and southern China need to provide twice or more heat energy for the same area, while those in the south require even more. In contrast, buildings in central and southern China have thinner walls, resulting in significant heat loss, thus requiring even more heat to maintain their heating capacity.

[0003] In central and southern my country, single-room apartments without centralized heating in winter are typically heated using portable or wall-mounted heating appliances. Most electric heaters on the market use heating wires, silicon carbide plates, oil-based heaters, or electric ceramic heaters as heating elements, generating heat with electricity. These heaters are clean and pollution-free, but their thermal efficiency is very low. Even with a 2200-watt heater, the heat source only provides warmth near the body, unlike centralized heating in northern regions where the entire house is warm. Therefore, in central and southern my country without centralized heating, conventional electric heaters on the market are simply unable to solve the room heating problem in these areas.

[0004] While high-powered electric heaters for baseboards currently on the market have solved the problem of room heating, they consume too much energy. Generally, only newly built homes can meet their electricity needs, but even then, they incur significant energy costs. Older homes, due to facility limitations, cannot provide this enormous amount of electricity and are therefore unusable.

[0005] Infrared ultra-high-efficiency electric heaters are an effective way to address the need for winter heating when large amounts of electricity are unavailable. Now, electric heaters using even more efficient graphene as heating elements have emerged. While the energy efficiency ratio has improved somewhat, and a slight energy saving has been achieved, it still cannot meet the actual needs of central and southern regions.

[0006] Therefore, how to provide a more efficient electric heater is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention aims to provide an ultra-high efficiency electric heater that utilizes infrared radiation, so as to at least partially solve one of the above-mentioned technical problems in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An ultra-high efficiency electric heater utilizing infrared rays includes a shell, a hot air duct, an infrared conversion mechanism, and an infrared heating mechanism;

[0010] The bottom of the housing is provided with an air inlet and the top is provided with an air outlet; the hot air duct is arranged inside the housing, and its inlet end and outlet end are respectively connected to the air inlet and the air outlet.

[0011] The infrared conversion mechanism is a plate-shaped structure and is located at the bottom of the hot air duct. The infrared heating mechanism is located inside the infrared conversion mechanism and above the air inlet.

[0012] Preferably, in the above-mentioned infrared ultra-high efficiency electric heater, the air inlet of the shell is provided with a room temperature air intake isolation net, the inner wall of the air outlet is provided with a limiting guide plate, the outer wall is provided with an anti-scalding net, and the outlet end of the hot air duct is fixed to the air outlet through the limiting guide plate and the anti-scalding net.

[0013] Preferably, in the above-mentioned infrared ultra-high efficiency electric heater, the bottom of the housing is provided with casters.

[0014] Preferably, in the above-mentioned ultra-high efficiency electric heater utilizing infrared rays, the infrared conversion mechanism includes a support frame and a surrounding plate. The support frame is fixed inside the room temperature air intake isolation net. The surrounding plate is a cylindrical structure with an air inlet hole on one side wall and fixed to the top of the support frame. An opening is provided on the opposite side wall. The infrared heating mechanism is fixed inside the surrounding plate and opposite to the air inlet hole.

[0015] Preferably, in the above-mentioned ultra-high efficiency electric heater utilizing infrared rays, a heat exchange cavity is formed between the infrared heating mechanism and the enclosure.

[0016] Preferably, in the above-mentioned infrared ultra-high efficiency electric heater, the bottom of the hot air duct is funnel-shaped.

[0017] Preferably, in the above-mentioned infrared ultra-high efficiency electric heater, a heat insulation cavity is formed between the hot air duct and the inner wall of the shell.

[0018] Preferably, in the above-mentioned infrared ultra-high efficiency electric heater, multiple heat insulation holes are evenly distributed along the edge of the air outlet of the shell to form a point-discontinuous structure.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a high-efficiency electric heater utilizing infrared rays, the main effects and advantages of which are:

[0020] It has higher thermal efficiency. Not only does the heat generated by the infrared heating mechanism itself heat the air, but also the infrared conversion mechanism set on the outside of the infrared heating mechanism intercepts and absorbs the infrared rays generated by the infrared heating mechanism, generating more heat and greatly improving the heating effect.

[0021] Easy to use, the device is equipped with casters at the bottom, making it easy to move to the area where it is used, which is very flexible and convenient;

[0022] It is noiseless, utilizing indoor cold air and heated air in hot air ducts to form a non-powered circulation conveying system, requiring no additional power components, resulting in better noise reduction and lower operating costs.

[0023] With enhanced safety, the hot air, heated by the infrared conversion and heating mechanisms, rises and exits through the air outlet, while the cold air enters through the air inlet at the bottom. The hot air duct has a heat insulation cavity between its side wall and the shell wall, and the air outlet edge is evenly distributed with point-discontinuous heat insulation holes. A limiting guide plate is provided between the air outlet duct wall and the shell, minimizing the transfer of heat to the shell and preventing overheating that could pose a safety hazard to the user.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Please see the appendix Figure 1-3 The present invention provides an ultra-high efficiency electric heater utilizing infrared radiation, comprising a housing 1, a hot air duct 2, an infrared conversion mechanism 3, and an infrared heating mechanism 4.

[0033] The bottom of the housing 1 is provided with an air inlet and the top is provided with an air outlet; the hot air duct 2 is installed inside the housing 1, and its inlet end and outlet end are connected to the air inlet and the air outlet respectively.

[0034] The infrared conversion mechanism 3 is a plate-shaped structure and is located at the bottom of the hot air duct 2. The infrared heating mechanism 4 is located inside the infrared conversion mechanism 3 and above the air inlet.

[0035] Specifically, the infrared heating mechanism 4 can use an infrared carbon fiber heating tube as the heat source.

[0036] Specifically, the housing 1 is a hollow cuboid housing with an air inlet at the bottom end and an air outlet near the top of the side wall. A room temperature air intake isolation net 10 is provided at the air inlet, a limiting guide plate 11 is provided on the inner wall of the air outlet, and an anti-scalding net 12 is provided on the outer wall. The outlet end of the hot air duct 2 is fixed to the air outlet through the limiting guide plate 11 and the anti-scalding net 12. A heat insulation cavity is formed between the hot air duct 2 and the inner wall of the housing 1. This design can prevent heat transfer between the hot air and the housing, ensure the temperature of the housing, prevent burns to the user, and improve safety.

[0037] Specifically, the room temperature air intake isolation net 10 is supported by a material with an extremely low heat transfer coefficient. A steel wire mesh with high-temperature plastic attached can be selected, and the outer shell will not get hot even after long-term use.

[0038] See attached document Figure 4 Multiple heat insulation holes 14 are evenly distributed along the edge of the air outlet of the shell 1, forming a point-discontinuous structure. By reducing the contact area between the anti-scalding mesh and the shell, the heat conduction speed is reduced, further preventing the shell temperature from becoming too high.

[0039] To further optimize the above technical solution, the bottom of the housing 1 is equipped with casters 13. This solution allows for easy movement and can be easily moved to houses that require heating, thus avoiding energy waste.

[0040] To further optimize the above technical solution, the infrared conversion mechanism 3 includes a support frame 30 and a surrounding plate 31. The support frame 30 is fixed inside the room temperature air intake isolation net 10. The surrounding plate 31 is a cylindrical structure with an air inlet hole on one side wall and is fixed to the top of the support frame 30. An opening is provided on the opposite side wall. The infrared heating mechanism 4 is fixed inside the surrounding plate 31 and opposite to the air inlet hole. This solution can effectively ensure the air intake efficiency of the air inlet. After the cold air at the bottom is heated in a concentrated manner, the hot air rises continuously under the action of pressure, and the cold air enters continuously along the air inlet, forming a gas circulation. No additional power equipment is required, saving production costs. Furthermore, the self-circulating structure can save a power source, further saving energy consumption.

[0041] Specifically, the enclosure 31 can be made of a high-temperature resistant black material or a high-temperature resistant material with a black coating on its surface.

[0042] Specifically, the enclosure 31 can also be made of metallic zinc or zinc oxide.

[0043] To further optimize the above technical solution, a heat exchange cavity is formed between the infrared heating mechanism 4 and the enclosure 31. The opening of the enclosure is narrowed and extended, which can prevent infrared rays from escaping into the hot air pipe, improve the exchange rate of infrared rays, and further concentrate heat to achieve rapid heating of air and improve heating efficiency.

[0044] To further optimize the above technical solution, the bottom of the hot air duct 2 is funnel-shaped.

[0045] Specifically, the principle of this solution is as follows:

[0046] After the infrared heating mechanism is turned on, it heats up rapidly and emits infrared rays. The infrared rays shine on the enclosure of the infrared conversion mechanism, converting the infrared rays into heat. At the same time, the high temperature generated by the infrared heating mechanism itself heats the air at the bottom of the hot air pipe. By making full use of the energy of infrared rays, the thermal efficiency of the device is further improved. After the air is heated, it is sprayed upward through the hot air channel and out through the air outlet. Since there is a heat insulation cavity between the shell and the hot air channel, heat can be prevented from being transferred to the shell, making it safer.

[0047] The low-temperature air below the flow channel expands in volume and decreases in density when heated to a high temperature. It then floats upward, reducing its pressure. The high-density cold air in the room is forced into the heat exchange chamber under the influence of air pressure, forming a non-powered circulation and transportation system for hot and cold air. The cold air in the room is heated and transported through the hot air channel to the air outlet, driving the circulation of hot and cold air in the room. This forms a silent and non-powered heating system with less energy consumption and lower operating costs.

[0048] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
