Description

Technical Field

[0001] This utility model relates to the field of heaters, and more specifically, to a vertical heater. Background Technology

[0002] A household upright fan heater is a common indoor heating device widely used in homes, offices, and other places. It converts electrical energy into heat energy and uses the principle of air circulation to quickly raise the ambient temperature. Its core function is to provide efficient and safe local heating, which is especially valuable in winter or cold regions. A typical upright fan heater mainly consists of heating elements, a fan system, a shell structure, a control module, and protective devices. The heating element usually uses PTC ceramic or metal heating wire, which generates heat through the action of electric current; the fan system includes a motor and fan blades, which is responsible for drawing in cold air from the air inlet, heating it through the heating element, and then expelling it from the air outlet; the shell is made of high-temperature resistant plastic or metal, forming an internal air duct and ensuring an aesthetically pleasing appearance; the control module integrates on / off, temperature adjustment, and timer functions, and some high-end models are also equipped with remote control or smart network functions. During operation, cold air enters the unit through the rear air inlet, is heated, and then blown out as warm air from the front air outlet, achieving heat circulation through forced convection.

[0003] In existing designs, vertical air heaters generally adopt a front-exhaust and rear-intake structure. Although this unidirectional ventilation mode can ensure the rationality of the airflow path, during long-term shutdown, dust, hair and other impurities can easily accumulate at the exposed rear air inlet. These impurities will be sucked into the machine when restarted and adhere to the heating element or fan blades, resulting in reduced heating efficiency, increased operating noise, and even safety hazards caused by overheating.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: A vertical fan heater, such as Figure 1 , Figure 2As shown, the main body 1 adopts a vertical columnar structure, and the base 2 has a built-in counterweight to enhance stability. A cable interface is provided on the base 2 to prevent the casing 5 from interfering with cable routing. The top surface of the main body 1 is the control panel, which integrates indicator lights and adjustment knobs. A rectangular air inlet 3 is located in the upper middle part of the back of the main body 1. An integrally formed dustproof grille is installed inside the air inlet 3. The front air outlet 4 has a honeycomb-shaped guide plate, which serves both guiding and protection functions. The area of ​​the air outlet is 1.4 times the area of ​​the air inlet 3 to create positive pressure airflow. The main body 1 contains metal heating wires and a fan. The casing 5 is injection molded from ABS engineering plastic. Its baffle 6 completely covers the air inlet 3, and the two side plates 7 are bent inward to form a 90° arc angle. When installing the casing 5, it is snapped onto the back of the main body 1, and the two side plates 7 slide against the side wall of the main body 1 until the baffle 6 contacts the back of the main body 1.

[0018] like Figure 2 As shown, the overall weight of the cover 5 is controlled within 300g. Stability is ensured through a dual fixation method of magnetic attraction and mechanical support. Furthermore, when the heater is operating, the removed cover 5 can be placed directly on the ground next to the heater. The support plate 8 increases the base area of ​​the cover 5 while lowering its overall center of gravity, thus ensuring stability when the cover 5 is placed alone. A 40×20mm galvanized iron plate is embedded on the back of the unit 1 as a suction block 9, corresponding to the N35 grade neodymium iron boron magnet embedded inside the baffle 6. This suction enhances the connection strength between the cover 5 and the unit 1.

[0019] like Figure 2 As shown, the neodymium iron boron magnet is covered with a 0.2mm stainless steel protective layer and is fixed in the baffle 6 sandwiched by a hot-melt column. Hot-melt column fixing is an assembly process that utilizes the hot-melt properties of plastic to achieve mechanical connection. Its core principle is to soften the plastic column by heating, and then deform it under pressure to form a rivet-like structure, thereby firmly fixing different components. The galvanized iron sheet surface is phosphated to avoid electrochemical corrosion. The neodymium iron boron magnet is mounted on the cover 5. When the machine is operating and generating heat, the cover 5 is not mounted on the machine body 1, preventing the neodymium iron boron magnet from being exposed to a high-temperature environment for a long time, which would weaken its magnetism.

[0020] like Figure 2 , Figure 3As shown, the lifting block 10 and the cover 5 are integrally formed. The groove 11 on the bottom surface of the lifting block 10 is 15mm deep, and the groove opening is tapered inward to form a 5° angle, conforming to the ergonomic finger grip curve. The lifting groove 12 on the back of the body 1 is 20mm deep, with a 2mm rounded corner transition at the top. The opening 13 at the top of the baffle 6 is 5mm wider than the lifting groove 12, ensuring that the body 1 can be lifted through the lifting groove 12 without disassembling the cover 5, making it easy to move the body 1 and the cover 5 together. When it is necessary to disassemble the cover 5, the user's fingers can reach down along the lifting groove 12 to the groove 11 and apply a lifting force away from the body 1, causing the cover 5 to slide away from the body 1.

[0021] When the heater is needed, the user can hold the main body 1 with one hand and apply force by gripping the lifting block 10 with the other hand. The cover 5 will slide off the main body 1, at which point the air inlet 3 and the air outlet 4 will form a one-way airflow path. To reinstall, first place the lower end of the support plate 8 against the edge of the base 2, and then gently push the upper part of the baffle 6 until a magnetic click is heard, indicating that the heater is in place.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
