Description
Technical Field
[0001] The utility model relates to the field of household appliances, in particular to a heater with high efficiency heating. Background Art
[0002] A heater is a device used to heat indoor air, its primary function being to provide a warm and comfortable environment. Heaters can employ a variety of different operating principles and configurations. They utilize electricity to generate heat to warm the indoor air. Electric heaters typically consist of an electric heating element and a fan. When the heating element is powered, it generates heat and transfers it to the surrounding air. Simultaneously, the fan blows the heated air out, rapidly circulating the indoor air and achieving a rapid heating effect. Electric heaters offer several advantages, including ease of operation, rapid heating, and portability. Because they generate heat using electricity, they do not require fuel and do not produce combustion-generated exhaust gases and pollutants. Furthermore, the heater's temperature can be adjusted, allowing users to select the appropriate heating temperature based on their needs.
[0003] However, traditional electric heaters present several challenges during use. First, due to their high power output, they typically use resistance heating elements, which generate heat through an electric current, thereby raising the temperature of the surrounding air. While simple and effective, this direct resistance heating method is relatively energy-inefficient and typically only draws in ambient air. Electric heaters or fan heaters are typically located on the ground, where the air temperature is relatively low. To heat the cooler ground air, a high power output is typically required. To achieve higher power output, electric heaters are typically designed with low resistance, which results in a higher current flow and, consequently, a larger power supply. This results in high energy consumption during operation for both targeted and whole-house heating fan heaters. Second, prolonged use of electric heaters significantly reduces air humidity. Moisture in the air evaporates as water vapor after being heated. However, because air has a fixed volume, the increase in moisture does not increase proportionally with rising temperature. Therefore, as electric heaters heat for extended periods, moisture in the air is continuously evaporated and expelled, causing the humidity in the air to gradually decrease, making the air in the environment dry. Furthermore, traditional electric heaters typically do not provide air circulation, which can lead to poor air flow in the room, affecting overall comfort and air quality. Utility Model Content

[0036] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0037] like Figure 1-6 As shown, this embodiment provides a heater.
[0038] A high-efficiency heating heater comprising:
[0039] The housing 100 has an air inlet and an air outlet, and the air outlet and the air inlet are arranged on the same side wall;
[0040] An air duct assembly is located inside the housing 100, and the two ends of the air duct formed are connected to the air inlet and the air outlet respectively;
[0041] The heating component 200 is located in the air duct and is arranged near the air outlet;
[0042] A cross-flow fan 300 is located between the heating component 200 and the air inlet;
[0043] The air duct formed by the air duct assembly inside the housing 100 is divided into an air inlet area and an air outlet area a by the cross-flow fan 300; the air outlet area a is provided with a reflow area b.
[0044] The above is the basic solution of this embodiment.
[0045] Specific reference Figure 1 and Figure 2 As shown, the housing 100 is configured as a rectangular parallelepiped shell structure, with the front face serving as the air inlet face and also serving as the air outlet face; the air inlet and the air outlet are provided on the front face;
[0046] A control panel 110 is provided on the top of the housing;
[0047] The cross-flow fan 300 is located between the air inlet and the heating component 200. When the cross-flow fan 300 is started, it drives the airflow in the air duct, so that a directional airflow is generated in the air duct. After passing through the heating component 200, the airflow forms hot air and is blown out from the air outlet. At the same time, the air outside the housing 100 enters the air duct through the air inlet, supplementing the airflow in the air duct to form a circulation.
[0048] When the airflow is output from the air outlet, a small amount of airflow has a direction inconsistent with the air outlet, and thus cannot be output from the air outlet. Instead, it collides with the inner wall of the shell and returns in the opposite direction of the output airflow;
[0049] In this embodiment, a reflow zone b is provided in the air outlet zone a. After being stopped in the reflow zone b, the returning airflow changes its moving direction again and is output toward the air outlet.
[0050] Based on the above settings, the return airflow and the normal output airflow are mixed and blown out from the air outlet, increasing the air output of the heater.
[0051] Preferably, in this embodiment, the heating component 200 is a quartz tube.
[0052] In this embodiment, the air outlet is provided with an air outlet net 120 , and the air outlet net 120 is arranged with air outlet holes.
[0053] When hot air is discharged from the air outlet, a small amount of air cannot pass directly through the air outlet. Instead, it collides with the air outlet mesh 120 between the air outlets, changing the direction of the airflow and forming a reverse airflow. This reverse airflow moves inward to the recirculation zone b, changes its direction again, and is discharged from the air outlet mesh 120 again.
[0054] In this embodiment, an air inlet grille 130 is provided at the air inlet.
[0055] Specifically, the air duct assembly at least includes an air duct housing 400 for separating the air inlet area and the air outlet area a, wherein a first end of the air duct housing 400 is connected to the air outlet, and a second end is close to the cross flow fan 300;
[0056] A return plate 500 is provided between the second end of the air duct housing 400 and the cross flow fan 300 .
[0057] Specific reference Figure 2 As shown, the air duct housing 400 is a shell with openings at both ends, and the air outlet area a is located inside the air duct housing 400; the cross flow fan 300 is connected to the second end of the air duct housing 400, and the opening at the first end of the air duct housing 400 is connected to the air outlet;
[0058] To ensure air outlet efficiency, in this embodiment, the air outlet completely covers the opening of the first end of the air duct housing 400, ensuring that the airflow output from the air duct housing 400 can be completely output from the air outlet.
[0059] In this embodiment, an extension portion 410 is provided on the upper end surface of the air duct shell 400, and the extension portion 410 extends backward to the top of the cross flow fan 300, so that the airflow output by the cross flow fan 300 can all enter the air duct shell 400, reducing the overflow airflow and ensuring the maximization of the air volume output from the air outlet.
[0060] Preferably, in this embodiment, the return plate 500 includes a V-shaped blocking portion 510 and a return portion 520, wherein the blocking portion 510 is connected between the air duct housing 400 and the cross flow fan 300, and the end of the return portion 520 faces the air outlet area a;
[0061] The lower part of the air outlet area a forms the recirculation area b.
[0062] Specific reference Figure 3 As shown, the cross-flow fan 300 includes a fan impeller 310 and an external fan housing 320. The fan housing 320 is provided with an air inlet portion 321 and an air outlet portion 322, and the air inlet portion 321 and the air outlet portion 322 are both arranged near the fan impeller 310. The airflow in the air inlet area enters the fan housing 320 through the air inlet portion 321, is driven by the fan impeller 310, and is blown out from the air outlet portion 322 on the other side.
[0063] In this embodiment, the return plate 500 is disposed at the air outlet portion 322 of the fan housing 320 and is fixed to the inner wall of the air outlet housing at the air outlet portion 322;
[0064] The return flow portion 520 faces the air outlet area a;
[0065] After the airflow changes direction and flows back near the air outlet, part of it enters the fan housing 320 and is driven again by the fan impeller 310 to form an airflow. A small amount of it enters the reflow area b of the reflow plate 500 and is stopped by the blocking part 510, changing its moving direction and moving toward the air outlet area a again.
[0066] The most significant feature of the cross-flow fan 300 is that the fluid flows through the fan impeller 310 twice, flowing in radially and then out radially, with the air intake and exhaust directions in the same plane, and the exhausted gas is evenly distributed along the width of the fan.
[0067] Preferably, in this embodiment, the blocking portion 510 and the return portion 520 are both arranged to be inclined relative to the air duct housing 400 , and the inclination angle of the blocking portion 510 is greater than the inclination angle of the return portion 520 .
[0068] Specific reference Figure 4 As shown, the blocking portion 510 is connected to the lower end of the air duct housing 400, and the other end extends into the fan housing 320 to reduce the backflow of air into the fan housing 320; the return flow portion 520 is located above the blocking portion 510, one end is bent into shape with the blocking portion 510, and the other end extends to the opening position of the fan housing 320, dividing the air outlet portion 322 of the fan housing 320 into two parts, and the return flow area b is located at the lower part.
[0069] Based on the above arrangement, the return portion 520 has an inclined upper end surface, so that the air outlet portion 322 of the fan housing 320 forms a flare along the air outlet direction, and the airflow forms a buffer at the flared portion, so that the hot air remains in a stable air outlet state when being blown out.
[0070] In this embodiment, the air inlet portion 321 of the fan housing 320 is provided with a guide edge 323 along the air inlet direction.
[0071] Specific reference Figure 3-Figure 6 As shown, the guide along the wind guide direction 323 is tilted and corresponds to the position of the air inlet.
[0072] In this embodiment, in order to cooperate with the principle that low-temperature air sinks and high-temperature air rises, the air inlet is set below the shell, and the heating component 200 and the cross-flow fan 300 are arranged in a straight line with the air outlet, and are located above the shell 100; therefore, the air inlet area of the air duct is an inclined path, so the guide edge 323 is set as an inclined surface, so that the supplementary air flow can enter the cross-flow fan 300 along the inclined direction, so that the moving direction of the supplementary air flow is consistent with the driving direction of the cross-flow fan 300 on the air inlet part 321, thereby improving the driving efficiency of the air flow.
[0073] Wherein, an inclined air inlet surface is provided below the front end surface of the housing 100, and the air inlet is located on the air inlet surface;
[0074] The air inlet direction is vertical and upward.
[0075] Based on the above arrangement, the air inlet surface can face the low-position air, thereby driving the low-temperature air at a lower position, so that a larger range of airflow circulation is formed outside the heater, thereby improving the heating efficiency. The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any person skilled in the art can make some changes or modify the technical content disclosed above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the present invention. However, any brief modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the technical solution of the present invention.
