Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater suitable for use in applications such as heating, drying and hot water supply.

[0002]

2. Description of the Related Art Conventional heaters include a type in which kerosene is burned to generate heat and a type in which heat is generated by electric resistance of a nichrome wire or the like.

[0003]

However, when a heater that burns kerosene or the like to generate heat is used as, for example, a hot air heater, the indoor air is contaminated with a bad smell or carbon monoxide, so that the heater becomes warm. There is a problem that the air inside the room must be replaced many times a day, which lowers the economic efficiency.

On the other hand, when a heater that generates heat by electric resistance is used, for example, as a hot air heater, air is sent directly to a heat-generating nichrome wire or the like by a blower to warm the heater. There is a problem that a large amount of electric power is always required in order to achieve this. In addition, there is a risk of failure due to disconnection depending on the usage time and the amount of heat.

An object of the present invention is to provide a heater capable of heating or warming a target portion economically without polluting air.

Another object of the present invention is to provide a heater capable of economically heating or warming a liquid such as water.

Another object of the present invention is to provide a heater which can efficiently generate heat and which is hardly broken down.

Another object of the present invention is to provide a heater which can efficiently perform both heating and hot water supply as required.

According to the first aspect of the present invention, there is provided a heater in which electrode plates are arranged on opposing surfaces of a heat-resistant electric insulating container, respectively, and the space between these electrode plates is filled, so that the carbon is placed in the heat-resistant electric insulating container. A particle group is spread, and a heater body is formed by the heat-resistant electrically insulating container, the electrode plate, and the carbon particle group. The heater body is housed in a heat-resistant sealed case, and traverses an upper space in the heat-resistant sealed case. And a heat medium flow pipe is disposed.

In such a heater, when a voltage is applied between the two electrode plates, a current flows from one electrode plate through a group of carbon particles to the other electrode plate. When a voltage is applied to the group of carbon particles and a current flows, spark discharge is generated in a certain portion at a contact point between the carbon particles, and high Joule heat is generated in that portion due to a high contact resistance in a certain portion. In addition, the carbon particles themselves also generate Joule heat due to the current and the specific resistance, and the addition of these causes the carbon particle group to reach a high temperature, generating high heat generation.

Since the heat medium flow pipe is arranged across the upper space in the heat-resistant sealed case accommodating such a heater body, warm air or hot air is generated by passing air through the heat medium flow pipe. Alternatively, hot water can be formed by supplying water to supply hot water, and the hot water can be heated by passing the hot water through a heat exchanger of a heater. In this case, the number of heat medium flow pipes may be one or more depending on the purpose.

When a voltage is applied to the group of carbon particles and a current flows, spark discharge is generated in a certain portion at a contact point between the carbon particles, and high Joule heat is generated in that portion due to a high contact resistance in a certain portion. In addition, the carbon particles themselves also generate Joule heat due to the current and the specific resistance, and the addition of these causes the carbon particle group to reach a high temperature, generating high heat generation.

[0015] Such a heater body is housed in an outer case, and a blower for taking in outside air and generating warm air by heat from the heater body is arranged in the outer case.

In addition, this heater is efficiently operated by spark discharge or Joule heat. The heater can generate heat and is hardly broken down without fear of disconnection. Furthermore, since the carbon particle group is housed in a closed heat-resistant electrically insulating container, it is possible to suppress contact with air and to suppress its wear.

In the outer case, a blower that takes in outside air and generates hot air by the heat from the heater body is arranged, a hot air outlet is provided in the outer case, and crosses the upper space in the heat-resistant sealed case. In addition, a heat medium flow pipe is disposed across the outer case.

In such a heater, when a voltage is applied between the two electrode plates, a current flows from one electrode plate through a group of carbon particles to the other electrode plate. When a voltage is applied to the group of carbon particles and a current flows, spark discharge is generated in a certain portion at a contact point between the carbon particles, and high Joule heat is generated in that portion due to a high contact resistance in a certain portion. In addition, the carbon particles themselves also generate Joule heat due to the current and the specific resistance, and the addition of these causes the carbon particle group to reach a high temperature, generating high heat generation.

Such a heater body is housed in an outer case, and a blower for taking in the outside air and generating warm air by the heat from the heater body is arranged in the outer case. When the outlet is provided, warm air can be generated by the heater body and the blower to supply warm air into the room from the outlet of the outer case, and can be used as a hot air heater.
