Description

Electric heater {ELECTRIC HEATER}

The present invention relates to an electric heater made of an extruded aluminum member. These electric heaters are lightweight, easy to assemble, and are suitable for inexpensive and rapid heating.

Conventional methods of raising room temperature by heating include 'heat radiation for heating' and 'hot air convection heat transfer for heating'. For example, in the oldest heating technology for burning coal or wood, wood can be burned in a stove to produce a flame that releases heat into the atmosphere to produce heat radiation. Heaters used to obtain thermal energy from the wood being burned can raise the temperature of the air around them, thus raising the temperature of the room, which is hot air convection heat transfer for heating.

As shown in FIG. 1, in the structure of a conventional industrial product, that is, an electric heater, an arcuate stainless steel plate 2 is provided in front of the steel housing 1. The stainless steel plate 2 has a concave portion, and a plurality of quartz pipes 3 are provided thereto. The crystal pipe 3 is electrically connected to emit infrared rays containing thermal energy. Next, the infrared rays are reflected by the stainless steel plate 2 to heat the area in front of the electric heater.

Such electric heaters, which can generate radiant heat, are inexpensive and fast to heat up, so that the user can feel warm very quickly when in the range of radiation. While radiating heat, only the person in the area receiving infrared light can feel warm, and if the person receives infrared light for a long time, the person feels dry and uncomfortable.

As shown in FIG. 2, the configuration of a convection heat transfer electric heater using air convection heat transfer for heating is mainly composed of a heating section 4, a connecting pipe conduit (not shown) and a plurality of steel sheets 5. Here, the heater 4 is provided with a heater and a pump, and the low volatile oil is stored. Upon heating, the oil can be gradually heated by the heater, transferred to the connecting pipe conduit by a pump, and the low temperature oil in the connecting pipe conduit back to the heating section 4, thereby forming a circulating flow. do. Since the connection pipe conduit is circulated around the steel plate 5 which is connected by the heating part 4 and closely arranged, when the heating oil flows, the temperature of the steel plate 5 increases. When low-temperature air passes between the steel sheets 5, the surface of the steel sheet 5 is heated by heat exchange with the surface of the steel sheets 5, and the temperature of the room can gradually rise by air convection heat transfer.

The advantage of the convection heat transfer electric heater described above is that the temperature of the room rises stably and in no case does the temperature become uneven. Therefore, it is possible to replace the heat radiation electric heater, but still has the following disadvantages.

1. This heater is heated with oil, which is preheated and sent to the steel plate to heat the steel plate, and then convection heat transfer can be initiated, in which the heating rate is very slow.

2. Structurally, the connection pipe conduit is provided for conveying hot oil, so that the oil should not be leaked, and the problem of expanding after the oil is heated must be overcome. This structure is complex, difficult to assemble, time consuming, and too expensive.

3. The leakage of oil by deformation should be prevented and the heat absorption characteristics and heat release characteristics of the hot oil should be taken into consideration, so that the parallel ubiquitous arrangement of steel plates made of stronger steels arranged at predetermined intervals from each other ( It should be used in the form of a piece. Due to the large weight of the steel sheet and the weight of the added oil pipe, the weight of the pump and the oil itself, this electric heater is too heavy and difficult to move.

4. Since the heating section 4 is to be provided with a connection pipe for conveying hot oil, it is simply necessary to increase or decrease the number of steel sheets and the amount of oil to produce heaters of various specifications suitable for various sizes of space. impossible. If the space is not adequate, an additional electric heater must be purchased, which is not economical.

Among the aforementioned drawbacks, consumers are generally more concerned about the slowness of raising the room temperature, so many users add fans to the convection heat transfer electric heater. However, the reason why the rate of raising the room temperature is actually slow is that the oil is first heated and then transferred to the steel sheet to heat it. Since this is an indirect heat conduction method, the heating rate is very slow. In this respect, adding a fan to the convective heat transfer electric heater only increases the efficiency of air convection, does not raise the room temperature, and has the disadvantage of generating noise by the fan.

In this respect, the inventors of the present invention have studied the structural shortcomings of conventional electric heaters based on many years of professional experience in design and development practices for various electrical devices. In addition, it has been found that the heat radiation electric heater has a limitation in its heating method. This heater only increases the number and power of the quartz pipe, can only increase the radiation area and the intensity of the emitted infrared light, and the efficiency cannot be improved. However, the inventors of the present invention believe that the convective heat transfer heater can be improved in terms of efficiency, and have been interested in its design, and have tried to provide a heater with increased heating speed, light weight, easy assembly and much cheaper.

In the above-described structure of the present invention, the receiving chamber and the heat absorbing member are both made of an extruded aluminum plate, and thus can be easily disassembled and assembled. They are lightweight, have a fast thermal conduction rate and can directly absorb the heat dissipated from the thermal energy of the electric heating pipe. There is no need to use oil to transfer thermal energy. The heat absorbing members closely arranged on both sides of the receiving chamber can increase the speed of air convection, causing the room temperature to rise quickly. Thus, the electric heater has the advantages of rapid heating, easy assembly, low cost and weight reduction, which is the main purpose of the present invention.

In addition, the receiving chamber and the heat absorbing member formed of the extruded aluminum in the main body portion of the present invention can be easily disassembled and assembled with each other. Therefore, the space occupied by the accommodating chamber accommodating the electric heating pipe and the number of heat absorbing members can be easily reduced or increased at the time of assembly without replacing the molding die, which greatly increases the manufacturing cost. The consumer can choose an electric heater of the appropriate specification and the required dimensions for the interior space without paying a very expensive price. Therefore, the scope of application of the present invention is widened, which is the second object of the present invention.

A third object of the present invention is to provide a convection heat transfer electric heater that can increase the speed of air convection heat transfer. In practice, the heat absorbing member can be made of pipes, so that the heat absorbing member has a chimney effect. Cold air enters the open end of the pipe to exchange heat within the heat absorbing member, and then the heated air is released at a high rate. Thus, according to the present invention, molecules of indoor air are stirred, and the speed of air convection increases without a fan.
