Description

Technical Field

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

[0002] A household fan heater is a common indoor heating device, mainly used in homes, offices, and other places. It converts electrical energy into heat energy and uses a fan system to blow hot air out to raise the ambient temperature. Its typical structure includes a heating element (such as a PTC ceramic or metal heating wire), a fan, a casing, a control module, and protective devices.

[0003] Currently, the air outlets of household heaters typically employ a mesh or grille design, covered with a protective mesh to prevent foreign objects from entering the machine or users from accidentally touching high-temperature components. This mesh is generally made of metal or high-temperature resistant plastic and is fixed to the outlet frame using clips, screws, or welding. However, this method of fixing makes disassembling the mesh for cleaning rather cumbersome. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a household heater.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a household heater, including a body, the front of which is provided with a mounting groove and an air outlet located in the mounting groove, the bottom surface of which is provided with a top slot and a bottom slot, the top slot being located above the air outlet and the bottom slot being located below the air outlet, a mesh being embedded in the mounting groove, the top of which is integrally formed with a top insert that mates with the top slot, the top insert abutting against the side wall of the top slot, the bottom of which is integrally formed with a bottom insert that mates with the bottom slot, a handle being fixedly connected to the side of the top of which faces away from the top insert, a suction plate being hinged to the side of the bottom insert facing away from the mesh, and a metal piece being embedded in the bottom slot that magnetically engages with the suction plate.

[0006] The present invention is further configured such that: a plurality of side slots are provided on the bottom surface of the mounting groove, the side slots are symmetrically distributed on both sides of the air outlet, and a plurality of side inserts corresponding to the side slots are integrally formed on the mesh, the cross-sectional area of ​​the side inserts gradually decreases along the direction away from the mesh.

[0007] The present invention is further configured such that: the attracting sheet is composed of a support plate and a neodymium iron boron magnet sheet embedded in the top surface of the support plate, and the metal sheet is located below the support plate.

[0008] The present invention is further configured such that the top surface of the neodymium iron boron magnet sheet is lower than the top surface of the supporting plate.

[0009] The present invention is further configured such that: a cover plate is provided on the top surface of the neodymium iron boron magnet sheet, the cover plate is embedded in the top surface of the support plate, and both the cover plate and the support plate are made of heat insulation material.

[0010] The present invention is further configured such that the lowest end of the air outlet is at least 50mm away from the bottom slot.

[0011] In summary, this utility model has the following beneficial effects: The plug-in / magnetic composite fixing mechanism enables tool-free quick disassembly of the mesh panel. The top slot provides primary support, while the magnetic component simplifies the bottom locking operation. The heat-insulating design ensures the magnet's operating temperature does not exceed 100℃, preventing demagnetization at high temperatures. All metal parts of the mesh panel are rust-proofed, facilitating direct cleaning of the disassembled mesh panel. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A household fan heater, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the unit 1 adopts a vertical box structure, with a rectangular mounting slot 2 on the front, 15mm deep, and a 5mm wide supporting frame around it. An air outlet 3 is centrally located at the bottom of the mounting slot 2, with a top slot 4 40mm above it and a bottom slot 5 50mm below it; both are through-type channels, 8mm wide and 12mm deep. The mesh 14 is made of 304 stainless steel, stamped with an overall thickness of 1.2mm and a mesh aperture of 3mm. The top insert 6 is integrally bent into the top of the mesh 14, 2mm shorter than the top slot 4, and after insertion, its sides abut against the side walls of the top slot 4.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the bottom of the bottom insert 7 and the mesh 14 are integrally bent and connected to the suction plate via a micro-hinge. The suction plate can rotate within a 30° range relative to the bottom insert 7. The suction plate is made of glass fiber reinforced PA66 and internally embeds an N35H grade neodymium iron boron magnet 12, ensuring that the neodymium iron boron magnet 12 can maintain its magnetism within the air outlet temperature range of 40-110℃ of the heater. The magnet size is 20×10×3mm. The metal sheet is made of galvanized steel plate and is 5mm larger than the suction plate. It is fixed to the bottom of the bottom slot 5 with countersunk screws. During installation, first insert the suction plate horizontally into the bottom slot 5, then rotate the mesh 14 around the hinge point between the bottom insert 7 and the suction plate to insert the top insert 6 into the top slot 4. Finally, press the mesh 14 to insert all the inserts into their corresponding slots.

[0022] like Figure 5 , Figure 6 As shown, the neodymium iron boron magnet 12 is recessed into the support plate 111mm, and its periphery is filled with high-temperature resistant epoxy resin for sealing. The cover plate 13 is made of mica sheet and is embedded in the upper surface of the support plate 11 together with the neodymium iron boron magnet 12 to reduce the influence of temperature on the neodymium iron boron magnet 12. At the same time, the cover plate 13 and the support plate 11 clamp the neodymium iron boron magnet 12 in the middle to prevent wear on the neodymium iron boron magnet 12. The lowest point of the air outlet 3 maintains a safe distance of 50mm from the bottom slot 5 to prevent hot air from blowing directly onto the magnetic assembly.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the side slots 9 are symmetrically arranged on both sides of the air outlet 3, 15mm from the edge. The slots have a trapezoidal cross-section, with a top width of 6mm and a bottom width of 4mm. Conical side inserts 10 are stamped on both sides of the mesh 14, with a thickness of 1.2mm at the base and tapering to 0.8mm at the ends. These inserts guide the mesh 14 during insertion, ensuring smooth movement. The handle 8 is made of silicone-coated aluminum alloy strip, 80mm in length, and is fixed to the top of the mesh 14 with two M3 stainless steel screws. The surface of the handle 8 has anti-slip textures and protrudes 20mm from the surface of the mesh 14 for easy gripping.

[0024] For routine cleaning, the user holds handle 8 and pulls the top of mesh 14 outward, then flips mesh 14 outward around the hinge axis to open it. Installation is done in reverse; the magnetic structure automatically compensates for assembly errors. Simultaneously, the top of mesh 14 bends inward towards the body 1. When rotating to remove mesh 14, the user must overcome the frictional force caused by the elastic deformation pressure of the top insert, preventing mesh 14 from falling off due to reasons other than human error.

[0025] 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.
