Description

Technical Field

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

[0002] Traditional heaters generate high heat through a heating element, which heats the surrounding air. The rising hot air creates convection, gradually raising the ambient temperature. However, typical heaters, such as baseboard heaters, have a small overall heat dissipation and heat transfer area. In the initial stages of use, they require a longer time to heat the surrounding air and generate enough heat to raise the room temperature. This means that initially, users may need to wait a while before feeling a significant increase in room temperature. This lack of flexibility reduces the overall user experience. Utility Model Content

[0003] This utility model provides a combined heating electric heater to solve the technical problems of poor initial heating effect and poor flexibility of use of existing electric heaters.

[0004] To solve the above problems, the combined heating electric heater provided by this utility model adopts the following technical solution:

[0005] The device includes a housing and a heating element disposed within the housing. The heating element is an infrared heating tube arranged in an array at intervals. An auxiliary heat dissipation cover is provided on the housing. The side wall of the auxiliary heat dissipation cover is provided with heat dissipation holes. The bottom end of the auxiliary heat dissipation cover is an open structure and is detachably connected to the housing. A heat-conducting plate is provided inside the auxiliary heat dissipation cover. The top end of the heat-conducting plate is fixedly connected to the top inner side of the auxiliary heat dissipation cover. The bottom end of the heat-conducting plate extends downward into the housing and is positioned on one side of the infrared heating tubes.

[0006] Furthermore, the upper end face of the housing is formed with a U-shaped groove that mates with the lower port of the auxiliary heat sink, and the lower port of the auxiliary heat sink is inserted into the U-shaped groove.

[0007] Furthermore, the outer walls at both ends of the U-shaped groove are provided with U-shaped grooves, and the lower port of the auxiliary heat sink is provided with threaded pins that are locked in the U-shaped grooves. After the threaded pins are locked in the U-shaped grooves, they are tightened by nuts.

[0008] Furthermore, the heat-conducting plates are arranged in n spaced intervals, where n≥2.

[0009] Furthermore, the bottom end of the housing is provided with detachable support legs.

[0010] Furthermore, the housing base plate includes an outwardly extending extension plate, and the extension plate is provided with a positioning sleeve for mounting the support leg, the support leg passing through the extension plate and extending into the positioning sleeve.

[0011] Furthermore, the support legs are covered with high-temperature resistant rubber sleeves.

[0012] Furthermore, it also includes a detachable heat sink plate located at the upper end of the housing, the heat sink plate having heat dissipation slots, and the lower surface of the heat sink plate having a U-shaped protrusion that mates with the U-shaped slot.

[0013] The beneficial effects of the combined heating electric heater provided by this utility model are:

[0014] 1. In this utility model, when the electric heater has just started working or needs rapid heating, an auxiliary heat dissipation cover can be installed. The heat dissipation holes on its side wall and the internal heat-conducting plate accelerate heat dissipation, ensuring the electric heater can quickly reach the preset temperature. By diffusing heat outward through the auxiliary heat dissipation cover, the heat dissipation area is effectively increased, improving the heat dissipation efficiency and heating effect of the electric heater.

[0015] In addition, the auxiliary heat sink is detachable, which facilitates the maintenance of the internal structure and improves the flexibility of use.

[0016] 2. In practical use, once the temperature stabilizes after the electric heater has provided warmth, the auxiliary heat dissipation cover can be removed as needed to avoid occupying too much space. The heat dissipation plate can then be placed on the upper part of the casing, improving flexibility during actual use.

[0017] 3. The support legs in this utility model are easy to assemble and disassemble, and convenient for transportation and storage. The rubber sleeve has a certain degree of elasticity, which allows the support legs to be locked in the positioning sleeve, and also provides some protection for the base plate at the placement location.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0028] An embodiment of the combined heating electric heater provided by this utility model:

[0029] like Figures 1 to 4 As shown, the device includes a housing 1 and a heating element disposed within the housing 1. The heating element is an infrared heating tube 2 arranged in an array at intervals. An auxiliary heat dissipation cover 3 is provided on the housing 1. The side wall of the auxiliary heat dissipation cover 3 is provided with heat dissipation holes 31. The bottom end of the auxiliary heat dissipation cover 3 is an open structure and is detachably connected to the housing 1. A heat-conducting plate 32 is provided inside the auxiliary heat dissipation cover 3. The top end of the heat-conducting plate 32 is fixedly connected to the inner side of the top of the auxiliary heat dissipation cover 3. The bottom end of the heat-conducting plate 32 extends downward into the housing 1 and is positioned on one side of the infrared heating tube 2.

[0030] The heat-conducting plate 32 can quickly transfer the heat generated by the infrared heating tube 2 to the auxiliary heat dissipation cover 3, and then diffuse the heat outward through the auxiliary heat dissipation cover 3, effectively increasing the heat dissipation area and improving the heat dissipation efficiency and heating effect of the electric heater.

[0031] In addition, the auxiliary heat sink 3 is a detachable structure, which facilitates the maintenance of the internal structure and improves the flexibility of use.

[0032] In this embodiment, the infrared heating tubes 2 arranged in an array of intervals are arranged in pairs both horizontally and vertically. Three heat-conducting plates 32 are arranged at intervals. The three heat-conducting plates 32 are respectively located on the outer sides of the two horizontally arranged infrared heating tubes 2 and between the two infrared heating tubes 2.

[0033] By setting a gap between the heat-conducting plate 32 and the infrared heating tube 2, it is ensured that the heat-conducting plate 32 will not damage the infrared heating tube 2 when installed vertically. On the other hand, it also ensures that the heat-conducting plate 32 and the infrared heating tube 2 are close to each other, thereby improving the heat transfer effect and efficiency.

[0034] In this embodiment, the upper end face of the housing 1 is formed with a U-shaped groove 11 that mates with the lower port of the auxiliary heat sink 3, and the lower port of the auxiliary heat sink 3 is inserted into the U-shaped groove 11.

[0035] The outer walls of both ends of the groove 11 are provided with U-shaped grooves 12, and the lower port of the auxiliary heat sink 3 is provided with threaded pins 33 that are locked in the U-shaped grooves 12. The threaded pins 33 are locked in the U-shaped grooves 12 and then fastened with nuts.

[0036] Specifically, during installation, the auxiliary heat sink 3 is first initially positioned and installed by inserting it into the U-shaped groove 11, while simultaneously securing the threaded pin 33 within the U-shaped groove 12. It is then tightened using bolts.

[0037] In this embodiment, the bottom end of the housing 1 is provided with a detachable support leg 13.

[0038] The bottom plate of the housing 1 includes an outwardly extending extension plate 14. The extension plate 14 is provided with a positioning sleeve 15 for mounting the support leg 13. The support leg 13 passes through the extension plate 14 and extends into the positioning sleeve 15.

[0039] The support leg 13 is covered with a high-temperature resistant rubber sleeve.

[0040] The support leg 13 is easy to assemble and disassemble, and convenient for transportation and storage. The rubber sleeve has a certain degree of elasticity, which allows the support leg 13 to be locked in the positioning sleeve 15, and also provides some protection for the base plate at the placement location.

[0041] In this embodiment, a heat sink 4 is detachably disposed at the upper end of the housing 1. The heat sink 4 is provided with a heat dissipation groove, and the lower surface of the heat sink 4 is provided with a spiral protrusion 41 that cooperates with the spiral groove 11.

[0042] In actual use, once the temperature stabilizes after being heated by the electric heater, the auxiliary heat dissipation cover 3 can be removed as needed, and the heat dissipation plate 4 can be placed on the upper part of the housing 1 to improve the flexibility in actual use.
