Description

Technical field

[0001] This invention relates to water vapor fireplaces. In particular, the present invention relates to the utilization of positive temperature coefficient (PTC) heating plate in a water vapor fireplace.

Background technology

[0002] With the rapid development of science and technology, household water vapor fireplaces are gradually transitioning from heating devices to decorative apparatuses, and significant progress has been made in the technology. Currently, water vapor fireplaces typically utilize halogen lamps, heating tubes, or heating wires as heating elements.

[0003] The halogen lamps have the drawbacks of high temperatures and a susceptibility to being touched in the installed position, leading to scalding. They have a lifespan of 500-600 hours and consume high amounts of power. The halogen lamps are made of materials such as quartz glass, which is likely to be damaged during transportation.

[0004] The heating tubes have the disadvantages of slow heating, a suboptimal initial vapor flame effect, an improved vapor flame effect after normal heating, the occurrence of a redness phenomenon, and poor safety. Uneven heating results in an uneven vapor flame effect. After a period of use, the insulation withstand voltage, leakage current, and insulation resistance of the heating tubes exceed the standard. They cannot be dry burned, and if temperature protection devices malfunction, the heating tubes may be destroyed due to dry burning and even cause fires, damaging surrounding materials.

[0005] The heating wires have the defects that they need to cooperate with cross-flow fans for heat dissipation, resulting in a large size, heavy weight, and high noise. After a period of use, the insulation withstand voltage, leakage current, and insulation resistance of the heating wires exceed the standard. They cannot be dry burned, and if temperature protection devices malfunction, the heating wires may be destroyed due to dry burning and even cause fires, damaging surrounding materials. Furthermore, the heating wires may be oxidized and burn out after long-term operation, affecting their service life and even causing electrical leakage.

[0023] As shown in FIGs. 2, 3, 4, 5 and 6, one side of the water tank 11 facing the LED lamp groups 5 is provided with a PTC heating plate 16 arranged in a length direction of the light-transmitting channel 7, and a plurality of uniformly arranged support bases 19 positioned on the lower side of the PTC heating plate 16 are connected and fixed to the water tank 11. The support base 19 is of a hollow structure, a cross section of the support base 19 is rectangular, and upper portions of two side surfaces of the support base 19 adjacent to the water tank 11 are provided with positioning grooves 25. Two parallel side surfaces of the PTC heating plate 16 are connected and fixed to positioning bars 27 that are matched with the positioning groove 25 and arranged in the length direction of the PTC heating plate 16. One positioning bar 27 on the PTC heating plate 16 is inserted into the positioning grooves 25 on the plurality of support bases 19, and at the moment, the PTC heating plate 16 is attached to the side surface of the water tank 11. Accordingly, the PTC heating plate 16 is inserted into the water tank 11, and the PTC heating plate 16 can be conveniently removed from or mounted on the water tank 11. By using the PTC heating plate 16, a safety factor is high, and the phenomenon of 'becoming red' on a surface of a heater such as an electric heating tube cannot be generated under any application condition. When an external temperature controller breaks down, a temperature of a heating surface of the PTC heating plate 16 does not exceed a set constant temperature, such that the PTC heating plate has an overtemperature protection function, and potential safety hazards such as scalding and fire disasters cannot occur. The PTC heating plate 16 has the advantages of small heat resistance and high heat exchange efficiency, automatically keeps at a constant temperature, and saves power. A temperature rise rate is fast and the atomization effect is fast, such that the water tank 11 can be heated evenly, and the mist effect is good. The PTC heating plate 16 is made of a PTC ceramic heating element and an aluminum pipe, thereby having long service life. The PTC heating plate 16 is changeable in shape, thin and light, and easy to mount.

[0024] As shown in FIGs. 2, 3, 4, and 5, an outer side of the PTC heating plate 16 is equipped with an L-shaped shielding cover 20. The shielding cover 20 is aligned and attached to one side of the support base 19 facing away from the side of the water tank 11. Two first round holes 22 are positioned at a position where the shielding cover 20 and the support base 19 are attached. A side of the support base 19 facing away from the water tank 11 has two second round holes 26 aligned with the first round holes 22. The support base 19 contains a positioning plate 23, and two ends of the positioning plate 23 are fixedly connected to support plates 24 that make contact with the inner wall of the second round holes 26 in the support base 19. The positioning plate 23 has two screw holes aligned with the second round holes 26. After inserting the PTC heating plate 16 into the support base 19, the L-shaped shielding cover 20 is placed on the outer side of the PTC heating plate 16. Then, the shielding cover 20 and the support base 19 are connected by means of connection screws, so as to achieve the purpose of shielding the PTC heating plate 16, and provide thermal insulation. During the installation of the connection screws that connect the shielding cover 20 and the support base 19, the positioning plate 23 is inserted in the support base 19, such that the support plates 24 on the positioning plate 23 make contact with the inner wall of the second round holes 26 in the support base 19. The connection screws then penetrate the first round holes 22 and the second round holes 26, and screwed into the screw holes on the positioning plate 23, to complete the installation of the connection screws. Since the positioning plate 23 is detachable, in response to determining that the internal threads of the screw holes are damaged due to excessive torque, the positioning plate 23 can be replaced. Moreover, there is a gap between the positioning plate 23 and the inner wall of the second round holes 26 in the support base 19, supported by the support plates 24. After the installation of the connection screws, a portion a rod of the connecting screw is exposed. In response to determining that the head of the connection screw is weakened due to corrosion caused by the heat generated by the PTC heating plate 16, a steel saw blade can be inserted into the space defined by the positioning plate 23 and the support plates 24, to cut off the connection screw without damaging other components. This allows for the removal of the shielding cover 20 and the replacement of the PTC heating plate 16 without influencing other parts.
