Description

Technical Field

[0001] This utility model relates to the technical field of partial improvement design of daily heating equipment, and in particular to a heating element with a temperature control protection device for use in a heater. Background Technology

[0002] Currently, most heaters on the market consist of a fan, heating element, and temperature control device, which are separate components. The temperature control device is typically installed inside the frame near the heating element. Heat from the heating element is transferred to the temperature control device via air conduction or convection, resulting in a slow response time. In cases of abnormal temperature increases, the temperature control device may not activate in time, potentially leading to overheating and a fire hazard. Furthermore, there are two main types of heating elements: one is a PTC heating element, which has high air resistance and noise, and its surface is usually electrified, making it prone to dust accumulation and power attenuation, affecting performance; the other is a commonly used mica sheet heating element (plastic frame + mica plate + heating wire), which has low air resistance, but the heating wire surface is electrified, posing a safety hazard.

[0003] In the prior art, patent CN217088194U discloses a series aluminum heating device, including a series aluminum finned heating element. The series aluminum finned heating element includes a heating tube and several heat sinks fitted onto the heating tube. The surface of the heat sinks has concave and convex grooves. Two terminals are led out from each end of the heating tube. The heating tube includes a metal shell, with ceramic heads embedded at both ends. Insulating filler is placed inside the metal shell, and heating wires are installed within the insulating filler. Lead-out rods are connected to both ends of the heating wires, extending outwards to form terminals. The device also includes a sleeve and a thermostat. The sleeve is fitted over the heating tube between the heat sinks, and the thermostat is fitted onto the heating tube and located on the side of the heat sink. This device uses a series aluminum finned heating element, allowing the voltage and power of the heating tube to be adjusted according to the sleeve length. The thermostat is directly mounted on the heating tube, reducing the number of thermostats required for the entire device. It provides rapid temperature measurement and has a wide range of applications due to its overall size.

[0004] Patent CN222012064U discloses a heating element, including a bracket with two sets of heating wire assemblies. A temperature sensing component is connected between the two sets of heating wire assemblies. The temperature sensing component includes a support plate connected to the bracket. A first connecting piece, a second connecting piece, and a fusible connecting piece are respectively provided on both sides of the support plate. The first connecting piece is connected to a temperature control connecting piece, which is equipped with a thermostat. The fusible connecting piece is connected to a fuse. A contact piece is provided between the fuse and the thermostat. By adjusting the spatial structure of the temperature sensing element, the thermostat and the disposable fuse are positioned between the two sets of heating wire assemblies. The creepage distance is ensured by physical isolation with a mica sheet. The thermostat provides overheat protection. The disposable fuse is set to disconnect at a temperature approximately 30°C higher than that of the thermostat. When the heater overheats, in the rare case of thermostat failure, the thermal protector can trip in time, effectively preventing the heater from dripping and burning or melting and burning.

[0005] In order to solve one of the above problems, this application provides a heating element with a temperature control protection device for use in a heater. Utility Model Content

[0031] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] 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.

[0033] Example 1

[0034] Reference Figure 1-2 As shown, this utility model discloses a heating element with a temperature control protection device for use in a heater. The heating element includes a heating tube 42 and multiple heat sinks 41. The heating tube 42 contains a heating wire with two terminals extending from each end for conducting electricity and providing heating. The heat sinks 41 are generally made of aluminum or aluminum alloy. Several heat sinks 41 are equidistantly riveted to the heating tube 42, and the heat from the heating tube 42 is dissipated through the heat sinks 41, greatly improving the heat dissipation effect of the heating element. Furthermore, a metal mounting assembly is fixed to the heating tube 42. The material of the mounting assembly includes, but is not limited to, aluminum and aluminum alloys, copper and copper alloys, iron, and stainless steel. The mounting assembly is located on the side of one of the heat sinks 41. A thermostat and a fuse are fixedly connected to the mounting assembly. The thermostat and fuse are connected in series and electrically connected to the live wire of the power supply. The two ends of the heating tube 42 are respectively connected to the neutral wire of the power supply and the thermostat / fuse. The thermostat and fuse are connected together by the mounting assembly and heating element 42. The mounting assembly quickly transfers heat from the heating element 42 (if it overheats) to the thermostat and fuse. In the event of an abnormal fan stoppage, the thermostat and fuse respond quickly, effectively protecting the heating element and the entire unit. Specifically, when the heating element temperature is abnormal, the thermostat responds promptly and automatically disconnects the power. After the heating element temperature drops, it can automatically reconnect the power to reset or be manually reconnected. If the thermostat fails to respond to abnormal temperatures and disconnects the power, the fuse will blow when the temperature reaches its tripping temperature, disconnecting the power and protecting the unit from overheating and fire.

[0035] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the mounting assembly is installed in the middle or end of the heating element, and the thermostat and fuse are installed on the left or right side, or at the top or bottom of the heating element, as shown below.

The first fixing piece 11 is mounted on the heating element 42 and can be riveted to the heating element 42 or embedded in the riveted portion of the heat sink 41. Figure 2 As shown in the power connection diagram, the live wire of the power cord is connected in sequence to the first ceramic housing thermostat 21 and the thermal fuse 31, and then to one side of the heating tube 42. The other side of the heating tube 42 is connected to the neutral wire of the power cord. The heating tube 42 can be one or more connected in parallel to be powered on.
