Description

Technical Field

[0001] The invention relates to the technical field of heating equipment, and more specifically to a ceramic far-infrared radiation electric heater. Background Art

[0002] Indoor heating is an indispensable need for people in northern my country in winter. Hot water heating has been used for a long time. In practice, we found that this traditional heating form has the following disadvantages: 1. The construction difficulty and construction volume are increasing with the increase of various supporting facilities in the city; 2. In terms of installation, the capital, manpower, and later repair and maintenance investment are very large; 3. The heat source is far away from each heating terminal, and the energy loss during transmission is large; 4. The heating equipment of each heat source is different, the energy conversion rate is low, and the energy loss is large; 5. Since the heating terminals are installed together, the control of each household is not great, and the energy waste is serious; 6. The raw material for hot water heating is coal. With the decrease of non-renewable energy coal year by year, the price of coal is also rising, and the heating cost is also rising. The living standards of urban and rural residents are constantly improving, and the replacement of daily necessities is also changing with each passing day. More and more people are starting to use electrical equipment such as electric heaters and air conditioners for winter heating, but these electrical heating equipment are inefficient, and the high electricity bills make people stay away from them. The working class can only regard them as luxury goods, which hinders the promotion of the electric heater market. An analysis of the drawbacks of current electrical heating equipment shows that the main drawbacks are low energy conversion rate, high price and serious energy waste.

[0003] Therefore, how to provide a ceramic far-infrared radiation electric heater that is efficient, energy-saving and more environmentally friendly, improves energy conversion efficiency and reduces energy consumption is a problem that technical personnel in this field urgently need to solve.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See attached Figures 1 to 4 The embodiment of the present invention discloses a ceramic far-infrared radiation electric heater, comprising a housing 1, a heating tube 5, a heat storage radiation plate 4, a heat reflection plate 6 and a heat insulation cotton 10.

[0030] The top surface of the housing 1 is open to form an assembly cavity; a plurality of heating tubes 5 are fixed in the assembly cavity to generate heat; the heat storage radiation plate 4 is an aluminum alloy plate, the upper surface of which is provided with a far-infrared ceramic coating 41, and the lower surface is fixed on the plurality of heating tubes 5 to store the heat generated by the heating tubes 5 and radiate it into the room;

[0031] The heat reflector plate 6 is fixed in the assembly cavity and is located below the heating tube 5 to reflect heat to the heat storage radiation plate 4; the heat insulation cotton 10 is coated on the lower surface of the heat reflector plate 6 to prevent heat loss.

[0032] In this embodiment, the heat reflector 6 has a bottom plate 61 and a wing plate 62. The wing plate 62 has two pieces and is symmetrically fixed on both sides of the top surface of the bottom plate 61. One end of the wing plate 62 away from the bottom plate 61 is fixed to the top of the inner wall of the outer shell 1. The wing plate 62, the bottom plate 61 and the heat storage radiation plate 4 together form a heating chamber, and the heating tube 5 is arranged in the heating chamber.

[0033] like Figure 3As shown, the bottom plate has a trapezoidal cross section, the wing plate is fixed to the bottom end of the inner wall of the shell, and there is a gap between the bottom plate and the bottom wall of the shell. The wing plate, the bottom plate and the heat storage radiation plate are combined to form a sealed trapezoidal heating cavity. The heating tube is located in the heating cavity. Part of the heat generated by the heating tube acts directly on the heat storage radiation plate for storage, and the other part is fed back to the heat storage radiation plate for storage through the heat reflection plate. The heat entering the heat storage radiation plate generates far-infrared radiation energy through the ceramic coating, which can directly act on the surface of the object and be converted into heat energy to increase the surface temperature of the object. At the same time, it can also be absorbed by indoor objects, walls, etc., and then transfer the heat energy to the indoor air through conduction and convection to achieve indoor heating. The heat insulation cotton can effectively reduce the loss of heat and improve the utilization rate of energy. In addition, when the power is off, the heat energy stored in the heat storage radiation plate can continue to be released to heat the room, so that the electric heater has the characteristics of "heating quickly and cooling slowly", the heating is more continuous and efficient, and the economic cost is low, which is suitable for ordinary families.

[0034] This embodiment can effectively reduce heat loss by providing a heat reflection plate and heat insulation cotton, ensuring that the heat generated by the heating tube can be absorbed and stored by the heat storage radiation plate, thereby improving resource utilization and being more energy-saving and environmentally friendly.

[0035] In order to further optimize the above technical solution, a bracket is fixed on the upper surface of the base plate 61, and multiple heating tubes 5 are fixed on the bracket; terminal blocks 7 are fixed at both ends of the shell 1 relative to the base plate 61, and the terminal blocks 7 are electrically connected to the heating tubes 5.

[0036] The bottom plate fixes the heating tube through a bracket (the bracket is a prior art and is not shown in the figure), and both ends of the upper surface of the shell are electrically connected to the heating tube through a wiring socket, and heat energy is generated by energizing the heating tube.

[0037] The heating tube can adopt an electromagnetic heating tube, which generates heat after being powered on. The heat loss can be reduced through the heat reflection plate. The heat generated by the heating tube can basically all be applied to the heat storage radiation plate, and the heating effect is more efficient.

[0038] In order to further optimize the above technical solution, the plurality of heating tubes 5 are threaded tubes or finned tubes; both ends of the plurality of heating tubes 5 are fixed with terminals that can be electrically connected to the terminal holder (7); the axis of the heating tube 5 is parallel to the length direction of the wing plate 62. Using threaded tubes or finned tubes as heating tubes is economical and practical. Figure 1 As shown, the number of heating tubes is not less than three, and the three heating tubes are arranged in parallel to ensure the effective supply of heat source. A heating wire is arranged inside the heating tube, and the heating wire is electrically connected to the terminal block through the terminal block. After heating, the heating wire generates heat, which is released into the heating cavity through the heating tube. The heat reflection plate reflects the heat, and the heat storage radiation plate can store the heat and generate far-infrared radiation energy, thereby achieving the indoor heating effect.

[0039] The heat reflector is made of highly reflective insulation material, which can reflect heat and reduce heat transfer. For example, some nano-insulation materials use nano-scale structural characteristics to significantly reduce the heat transfer rate of thermal conduction, convection and radiation, thereby achieving efficient heat reflection effect.

[0040] The thermal storage radiation panel is an aluminum alloy plate. By integrating thermal storage materials inside it, it stores heat during off-peak hours and releases heat when needed, thereby improving energy efficiency. Its working principle is to use radiation heat transfer to directly transfer heat to indoor objects and people in the form of infrared rays, reduce air convection, and improve thermal energy utilization. Through the heat storage function, energy consumption is transferred to off-peak hours, reducing operating costs; the radiation heat transfer method reduces air convection and avoids the dryness and windy feeling of traditional convection heating systems.

[0041] In order to further optimize the above technical solution, the heat storage radiation plate 4 is a corrugated plate, and the lower surface of the heat storage radiation plate 4 is provided with slots corresponding to the plurality of heating tubes 5 one by one, and the heating tubes 5 are inserted into the slots.

[0042] The side wall of the slot is integrally formed with the heat storage radiation plate. The thickness of the heat storage radiation plate is no more than 1 cm. The heating tube is plugged into the slot, which is equivalent to the heat storage radiation plate and the heating tube forming a whole. The heat generated by the heating tube can directly act on the heat storage radiation plate and store heat.

[0043] In order to further optimize the above technical solution and improve the safety factor of the electric heater, a mesh cover 2 is also included. The mesh cover 2 is detachably connected to the top surface of the shell 1 to cover the assembly cavity.

[0044] like Figure 3 As shown, the mesh cover is a "J"-shaped stainless steel mesh cover, and the inner wall of the shell is provided with a slot. The edge of the mesh cover is hooked in the slot by a hook. The mesh cover and the shell are detachably connected by a snap connection, which can facilitate the replacement or cleaning of the heat storage radiation plate.

[0045] In order to further optimize the above technical solution, an end cover 3 is further included. Two end covers 3 are provided. The two end covers 3 are respectively covered at both ends of the top surface of the shell 1 and are symmetrically distributed on both sides of the mesh cover 2 to cover the wiring socket 7.

[0046] like Figure 1 and 2 As shown, the outer shell is a rectangular shell, and terminal blocks and intelligent control systems are provided at both ends along its long axis direction for controlling the heating temperature of the heating tube. An infrared receiving device is also provided to realize remote control. After the mesh cover is buckled into the assembly cavity, the end covers are covered on the two "J"-shaped limbs of the mesh cover and cover the terminal blocks and other electrical components, making the overall structure compact, the electric heater can be lighter and thinner, and reducing space occupancy.

[0047] In order to further optimize the above technical solution, ventilation grilles 9 are provided on the end cover 3 and the bottom wall of the shell 1. The ventilation grilles can dissipate heat, prevent damage to some electrical components caused by excessive heat in the heating pipe, and increase the service life of the electric heater.

[0048] In some other specific embodiments, a plurality of mounting plates 8 are further included, and the plurality of mounting plates 8 are evenly fixed on the outer bottom wall of the housing 1 so as to install the electric heater on an indoor wall or ceiling.

[0049] The mounting plate can be used to install the electric heater at a high position on the indoor wall or on the ceiling without taking up indoor space. While meeting the indoor heating needs, it will not reduce the indoor use effect.

[0050] The electric heater provided by the present invention can be installed on the ceiling, wall or ground, supports modular splicing, and is suitable for different space requirements.

[0051] In order to further optimize the above technical solution, the heat insulation cotton 10 is filled between the inner bottom wall of the shell 1 and the lower surface of the heat reflection plate 6. The heat insulation cotton can prevent the loss of heat and ensure the heating effect.

[0052] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
