Description

Technical Field

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

[0002] A heater is a device that converts electrical energy into heat energy to provide heating for the indoor environment. It is suitable for residential, office, medical, and educational settings.

[0003] Currently, heaters typically consist of a casing, inside which electrical components are housed. The casing includes a base, on which are a front and rear shell. The grille on the rear shell serves as the main inlet for cold air. The cooler, denser air in the room naturally sinks under gravity and is drawn into the heater through these slots. The grille on the front shell serves as the main outlet for hot air. After being heated by the heating elements or heat sinks inside, the air becomes less dense and naturally rises, eventually exiting through the front grille. This process of cold air entering through the rear shell, heating inside, and hot air exiting through the front shell creates a continuous natural convection circulation, which is the core power source for the heater to heat the air.

[0004] Since the grilles on the front and rear shells are exposed, they tend to accumulate dust after long-term use and require cleaning. However, because the grilles are installed on the front and rear shells, which are molded as a single piece, they cannot be disassembled separately. The cleaning operation can only be carried out on the shell, which is cumbersome and not thorough enough. Utility Model Content

[0005] The purpose of this utility model is to provide a heater to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a heater, including a housing, the housing including a base, a front shell and a rear shell disposed on the base, a front grille disposed on the front shell, a rear grille disposed on the rear shell, the front shell being fixedly connected to the base, the rear shell being detachably mounted on the front shell via a connecting assembly, the rear grille being integrally formed with the rear shell, the connecting assembly including a plurality of plugs disposed along the contour edge of the front shell and a plurality of sockets disposed along the contour edge of the rear shell for plug insertion, the plugs and sockets being connected by fastening screws; The front grille is detachably mounted on the front shell via an elastic snap-fit ​​structure. The outer wall of the front shell has a groove for embedding the front grille. An opening is provided in the middle of the groove. Several through slots are provided along the contour edge of the bottom wall of the groove. The elastic snap-fit ​​structure includes several elastic inserts provided along the contour edge of the front grille. Each elastic insert includes a piece body for penetrating the through slot and a raised part inclined at the end of the piece body. When the piece body penetrates the through slot, the raised part can tilt upward and elastically abut against the top inner wall of the through slot.

[0007] As a further feature of this invention, the fastening screw includes a screw body and a screw head. The end of the plug facing away from the front housing has a threaded hole that matches the screw body. The insert has a through hole for the screw body to pass through. The outer wall of the rear housing has multiple grooves that communicate with the through hole. The screw head is used to be embedded in the groove.

[0008] As a further feature of this invention, an elastic rubber ring is provided at the end of the plug facing away from the front shell, and the elastic rubber ring is made of rubber material.

[0009] As a further feature of this invention, the tilt angle of the raised portion is 30°-45°.

[0010] As a further feature of this invention, a lifting groove is provided on the rear shell.

[0011] As a further feature of this invention, both the front and rear shells are made of heat-resistant plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Before cleaning the front and rear grilles, this invention allows for the removal of fastening screws to loosen the fastening of the plug and sleeve. This enables the rear shell to be pushed, separating the sleeve from the plug and allowing the rear shell to be removed from the front shell. This allows for separate cleaning of the rear grille on the rear shell. After the rear shell is removed, the elastic insert located inside the front shell is exposed. By applying vertical pressure to the insert, the tilted and raised portion is deformed into a straight state, releasing its contact with the inner wall of the through groove, thus unlocking and separating it. This allows the front grille to be removed for separate cleaning. After cleaning, the front grille can be inserted into the groove, allowing the elastic insert to penetrate the through groove. The inner wall of the through groove then applies pressure to the raised portion. The pressure flattens the grille, allowing it to penetrate the slot and elastically contact the top inner wall of the slot, thus locking it in place and installing the front grille. Finally, the rear shell is assembled with the front shell, and the plug is inserted into the socket for pre-connection. The plug and socket are then connected using tightening screws, completing the assembly of the equipment and simultaneously installing the rear grille. This process allows the front and rear grilles to be removed separately for thorough cleaning. Even after removal, the base and front shell remain, supporting the internal electrical components without requiring complete disassembly, facilitating reassembly and making operation convenient, simple, and time-saving.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-9As shown, a heater includes a casing. Inside the casing are a core heating element, an air circulation system, a control and adjustment system, a safety protection device, and a circuit system. During operation, the core heating element converts electrical energy into heat energy. The heated element then transfers heat to the heat sink or heat transfer oil in contact with it via heat conduction. The heat is ultimately transferred to the air through convection, heating the indoor air. The casing includes a base 1, on which a front shell 2 and a rear shell 3 are mounted. Both the front shell 2 and the rear shell 3 are made of heat-resistant plastic, such as PPS plastic, which has good heat resistance and a long service life. The rear shell 3 has a lifting groove 17, allowing it to be lifted by inserting a hand into the groove 17, facilitating its assembly and disassembly. The front shell 2 has... A front grille 4 is provided, and a rear grille 5 is provided on a rear shell 3. The front shell 2 is fixedly connected to the base 1, and the rear shell 3 is detachably installed on the front shell 2 via a connecting assembly. The rear grille 5 is integrally formed with the rear shell 3. The connecting assembly includes multiple plugs 6 provided along the contour edge of the front shell 2 and multiple sockets 7 provided along the contour edge of the rear shell 3 for inserting the plugs 6. The plugs 6 and sockets 7 are connected by fastening screws. The front grille 4 is detachably installed on the front shell 2 via an elastic snap-fit ​​structure. A groove 8 for embedding the front grille 4 is provided on the outer wall of the front shell 2, and an opening 9 is provided in the middle of the groove 8. Several through slots 10 are provided along the contour edge on the bottom wall of the groove 8. The elastic snap-fit ​​structure includes several elastic inserts 11 provided along the contour edge of the front grille 4. The elastic insert 11 includes a plate portion for penetrating the through groove 10 and a raised portion inclinedly disposed at the end of the plate portion. When the plate portion penetrates the through groove 10, the raised portion can tilt upward and elastically abut against the inner wall of the top of the through groove 10. Before cleaning the front grille 4 and the rear grille 5, the fastening screws can be removed to release the fastening of the plug 6 and the sleeve 7. Then the rear shell 3 can be pushed to separate the sleeve 7 from the plug 6, thereby removing the rear shell 3 from the front shell 2. The rear grille 5 on the rear shell 3 can be cleaned separately. After the rear shell 3 is removed, the elastic insert 11 located inside the front shell 2 is exposed. By applying vertical pressure to the plate portion, the inclined raised portion is deformed into a straight state, releasing the abutment against the inner wall of the top of the through groove 10, thus unlocking and separating the front grille 4 and the rear grille 5. The grille 4 is removed and cleaned separately. After cleaning, the front grille 4 can be inserted into the groove 8, allowing the elastic insert 11 to be inserted into the through groove 10. The insert 11 then penetrates the through groove 10, and the inner wall of the through groove 10 applies pressure to the raised portion, flattening it and allowing it to penetrate the through groove 10 and elastically contact the top inner wall of the through groove 10, achieving a snap-fit ​​lock. This completes the installation of the front grille 4. Finally, the rear shell 3 is assembled with the front shell 2, and the plug 6 is inserted into the socket 7 for pre-connection. Then, the connection between the plug 6 and the socket 7 is achieved by tightening the screws, completing the assembly of the equipment and simultaneously installing the rear grille 5. Through the above operations, the front grille 4 and rear grille 5 can be removed separately for cleaning, resulting in a more thorough cleaning.Furthermore, even after removing the front grille 4 and rear grille 5, the base 1 and front shell 2 remain, still supporting the internal electrical components without requiring complete disassembly of the entire device. This facilitates device repositioning, making operation convenient, simple, time-saving, and labor-saving. The tilt angle of the raised portion is 30°-45°, and the elastic insert 11 is made of plastic.

[0017] Please see Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the fastening screw includes a screw body 12 and a screw head 13. A threaded hole 14 matching the screw body 12 is provided at the end of the plug 6 away from the front housing 2. A through hole for the screw body 12 to pass through is provided inside the socket 7. Multiple grooves 15 communicating with the through hole are provided on the outer wall of the rear housing 3. The screw head 13 is used to embed into the groove 15. By passing the screw body 12 through the through hole and threadedly connecting it to the threaded hole 14, a fastening connection between the plug 6 and the socket 7 can be achieved. After the connection is completed, the screw head 13 will be embedded accordingly. Inside the groove 15, the nail head 13 can be hidden to prevent accidental contact that could loosen the fastening screw. An elastic rubber ring 16 is provided at the end of the plug 6 away from the front shell 2. The elastic rubber ring 16 is made of rubber material. When the plug 6 is inserted into the socket 7 and connected by the fastening screw, the elastic rubber ring 16 will be squeezed, causing the elastic rubber ring 16 to undergo elastic deformation and push the plug 6 in the opposite direction. This makes the thread engagement between the fastening screw and the threaded hole 14 more secure, improving the connection strength.
