Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically a heater. Background Technology

[0002] Currently, heaters on the market generally convert electrical energy into heat energy through electric heating elements, and then transfer the heat out through air convection or radiation heat exchange.

[0003] Most existing household electric heaters use electric heating elements for heating, such as the portable heater disclosed in Chinese utility model patent CN202420767247.5, the PTC infrared radiation heating element composite heater disclosed in Chinese utility model patent CN202420445440.7, and the connection structure and heater of a heater heating bracket disclosed in Chinese utility model patent CN202323610975.X. These heaters rely on the heat generated by the electric heating elements during operation to achieve heating. However, electric heating elements consume a lot of energy during operation and have a short lifespan. Furthermore, they generate localized high temperatures, affecting the user's heating experience and posing safety hazards. Therefore, further improvements are necessary. Utility Model Content

[0004] The present invention aims to provide a heater to overcome the shortcomings of the prior art.

[0005] A heater designed for this purpose includes a main body, on which a front panel, a rear panel, a fan, and an air outlet are provided. The front panel and the rear panel are spaced apart front to back, and an intermediate plate is provided between them. The intermediate plate forms a front air duct and a rear air duct with the front panel and the rear panel, respectively. A heating film or heating coating is provided on the inner wall of the front panel, and / or the inner wall of the rear panel, and / or the front wall of the intermediate plate, and / or the rear wall of the intermediate plate. The air outlet and the fan are arranged vertically.

[0006] The heating film is a flexible heating film, and is adhered to the inner wall of the front panel, and / or the inner wall of the rear panel, and / or the front wall of the middle plate, and / or the rear wall of the middle plate; or, the heating coating is a heating paint, and is applied along the inner wall of the front panel, and / or the inner wall of the rear panel, and / or the front wall of the middle plate, and / or the rear wall of the middle plate.

[0007] The front panel, and / or the rear panel, and / or the middle panel are made of a high-temperature resistant transparent, translucent, or opaque material, and the heating film or the heating coating is made of a transparent, translucent, or opaque material.

[0008] The main body is provided with a circuit board, and electrodes are respectively provided at both ends of the heating film or heating coating. The electrodes are electrode plates and are attached to both ends of the heating film or heating coating, or the electrodes are electrode coatings and are applied to both ends of the heating film or heating coating. The heating film or heating coating is connected to conductive wires through the electrodes and is electrically connected to the circuit board through the conductive wires.

[0009] The fan is a cross-flow fan and is located below the front air duct and the rear air duct. The axis of the fan extends along the length of the air inlet end of the front air duct and the rear air duct. The circuit board is also electrically connected to the fan.

[0010] The two electrodes at both ends are directly connected to the conductive wires.

[0011] Alternatively, a connecting line is provided between the two electrodes and they are electrically connected through the connecting line, and the connecting line is further connected to the conductive line.

[0012] The main body includes a surrounding panel, which surrounds the front panel and the rear panel and has a bottom partition on its lower side. The surrounding panel, the front panel, the middle panel, and the bottom partition form the front air duct, and the surrounding panel, the rear panel, the middle panel, and the bottom partition form the rear air duct.

[0013] The intermediate plate is fixed to the enclosure and / or the bottom partition by snaps or fasteners, and a communication channel is formed between the intermediate plate and the enclosure. The front air duct and the rear air duct are connected to each other through the communication channel. A base is also provided at the bottom of the enclosure.

[0014] The air outlet is located on the enclosure, or the front panel, or the rear panel, and the bottom partition, or the enclosure, or the front panel, or the rear panel is also provided with a light-emitting element.

[0015] The base includes a front base plate, a rear base plate, and support feet. The rear base plate is fixed to the rear side of the front base plate, and the two form an open-top assembly cavity. The bottom partition plate is provided with several connecting holes. The front air duct, the rear air duct, and the assembly cavity are interconnected through several connecting holes. An assembly plate is fixed inside the assembly cavity, and a fan is fixed on the assembly plate. A circuit board is also fixed inside the assembly cavity.

Several air inlet holes are provided on the front or rear base plate.

[0016] This invention, through structural improvements, utilizes the intermediate plate to form front and rear air ducts with the front and rear panels respectively, resulting in at least two air ducts inside the main unit. Combined with the fan's blowing action, this not only reduces air turbulence but also increases the intake and exhaust volume of the main unit, achieving large-area airflow. This reduces the safety issue of localized overheating during operation. Furthermore, heating films or coatings are provided on the inner walls of the front and / or rear panels, and / or the front and / or rear walls of the intermediate plate. These heating films or coatings heat up quickly, generating heat immediately upon power-on, exhibiting high thermal efficiency and low energy consumption. Combined with the large-area airflow of the front and rear air ducts, the heater achieves large-scale heat radiation in both front and rear directions. Additionally, the rapid blowing of hot air from the outlet effectively warms the surrounding environment, improving the user experience. Attached Figure Description
