Abstract
An electric heater includes primarily an S-shaped air channel which is provided in a body, at least one heating unit which is provided in the air channel, and at least one heat energy conversion unit which is close to an inner wall of the air channel and close to the heating unit. An interior of the heat energy conversion unit is defined with a passage. Hot air can be directed rapidly by a principle that hot air ascends, through the S-shaped air channel. Heat energy produced by the heating unit is absorbed by the heat energy conversion unit and is then carried away by an air power of the passage, so as to achieve effects of heat accumulation and dissipation.
Description
- a) Field of the Invention
- The present invention relates to an electric heater and more particularly to an electric heater which is provided with effects of heat accumulation and dissipation and blows out hot air by a principle that hot air ascends.
- b) Description of the Prior Art
- An electric heater has become a necessary appliance to many people now. Especially that in winter or when weather temperature drops abruptly, we all need an electric heater to keep body temperature from catching a cold. In addition, an elderly person, as being weak, relies more on an electric heater to maintain his or her body temperature. In an early day when weather temperature is too low that health can be threatened, we often use stoves or charcoals to set a fire to increase body temperature, prohibiting the body temperature from changing with the weather temperature. Although this method of warmth keeping can achieve the effect of warmth keeping, the effect is not perfect; as hot air only dissipates in front of the stoves or charcoals, and one must always add the charcoals to keep the stoves burning. Furthermore, one important issue is that it is highly toxic in the burning and people can be poisoned easily, which is extremely risky.
- As time changes and continual progressiveness of technologies, this method of warmth keeping has been already achieved by an electric appliance and an electric heater sold on a market can be versatile, with various air blowing effects and various heating methods. On the other hand, a difference of apparatus also affects an entire effect of using the electric heater. An air channel in an interior of a conventional electric heater is mostly a straight channel and therefore, hot air is sent out merely by air pressure and there is no effect of heat accumulation. If high temperature hot air is required, then higher heat energy can be released merely by depending upon a heating power of the electric heater itself. Therefore, to achieve a user's requirement, it will often waste electricity on heating.
- The primary object of the present invention is to provide an electric heater, wherein an interior of a body is accommodated with an S-shaped air channel which is defined with an air inlet at a bottom of the body and an air outlet at a top of the body, the air inlet of the air channel is provided with an air guiding element which guides air into the air channel, an interior of the air channel is provided with at least a heating unit, a place close to an inner wall of the air channel and close to the heating unit is provided with at least a heat energy conversion unit which is made by a metallic material, and an interior of the heat energy conversion unit is defined with a passage allowing air to pass through. Therefore, when air enters into the air channel through the air guiding element, near infrared radiation energy produced by the heating unit can be absorbed by the heat energy conversion unit to achieve a heat accumulation effect. Next, air which carries the heat energy flows toward the air outlet through the passage to achieve a heat dissipation effect. By the aforementioned technologies, the issues existing in the conventional electric heater that the air channel is mostly a straight channel through which hot air is sent out merely by air pressure, thus bearing no heat accumulation effect and that when high temperature hot air is required, higher heat energy can be released merely relying on a heating power of the electric heater itself, thus often wasting electricity on heating to meet the user's requirement, can be solved. In addition, through the S-shaped air channel, hot air produced by the heating unit can be directed rapidly by a principle that hot air ascends. Besides, the heat energy produced by the heating unit can be absorbed by the heat energy conversion unit and then can be carried away through an air power of the passage, thereby achieving the practical progressiveness of the effects of heat accumulation and dissipation.
