Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating device with an ion generation function that can stably supply negative ions and / or positive ions into the air and efficiently burn fuel to heat efficiently.
[0002]
[Prior art]
Negative ions in the air are said to have the effect of relaxing inhaled people. In addition, it has been confirmed that a sterilization effect can be obtained by the interaction of negative ions and positive ions in the air. Therefore, negative ion generators and devices that generate both negative ions and positive ions have been developed. As these ion generators, devices utilizing the Leonard effect, devices utilizing spontaneously polarized ore, and devices utilizing interelectrode discharge or discharge plasma are known. In addition to being used alone, these ion generators are often mounted on home appliances, particularly heaters. In the case where an ion generator is mounted on a heater, a technique for efficiently performing ion generation / diffusion and heating simultaneously is important.
[0003]
FIG. 6 shows a configuration example in which the ion generator is mounted on the heating device. In FIG. 6, reference numeral 62 indicates a fan heater which is an example of a heating device. The fan heater 62 is provided with a ventilation path 72 extending from the intake port 70 to the warm air outlet 64. In the middle of the ventilation path 72, a burner 68 that generates heat by burning fuel, a blower 66, and an ion generator 60 are arranged.
When the operation of the fan heater 62 is started, the air blowing means 66 is operated and air is sucked from the air inlet 70. The sucked air passes through the ventilation path 72 and is heated by the burner 68 and is discharged from the hot air outlet 64 to be heated. Simultaneously with the start of the operation of the fan heater 62, ions are generated from the ion generator 60 and supplied to the ventilation path 72, so that warm air containing ions is discharged from the hot air outlet 64.
An example of a heating device incorporating an ion generator is described in Patent Document 1.

[Problems to be solved by the invention]
However, the configuration of the conventional example of FIG. 6 has the following problems. Usually, the amount of air discharged from the hot air outlet 64 by the air blowing means 66 changes in accordance with the heating operation status of the fan heater 62. That is, the air volume increases when heating rapidly, and the air volume decreases when heating is hardly performed. Even if the ion generator 60 generates ions under the same conditions, if the air volume from the warm air outlet 64 changes, the supply amount of ions into the room and the ion concentration distribution in the room will change. For example, when the amount of air from the hot air outlet 64 is small, ions are not uniformly distributed in the room, and only the vicinity of the fan heater 62 has a high ion concentration. In order to keep the distribution of ions in the room in a preferable state regardless of the heating operation status, the ion generation amount, the discharge air amount, and the hot air outlet 64 are taken into consideration in consideration of both the heating operation condition and the ion distribution status. It is necessary to optimize the orientation and shape. However, the setting is very difficult. In practice, the air volume and the air direction are set with priority on heating, and the ions are sacrificed when they are uniformly distributed in the room.
Furthermore, there are cases where heating is performed while supplying ions, heating is performed without supplying ions, and ions are supplied without heating, and a program for controlling the air volume and direction is prepared to handle all operating conditions. It is difficult to do.
The present invention has been made in view of the above-described problems. When only heating is performed, an air volume and a wind direction suitable for heating are obtained to efficiently heat, and when only ion supply is performed, ion supply is performed. When supplying ions efficiently while obtaining the air volume and direction suitable for heating, blow out warm air with the air volume and direction suitable for heating, and ion with the air volume and direction suitable for ion supply. The heating apparatus with an ion generating function which can blow out the air containing this is provided.
[0006]

【Example】
Hereinafter, an embodiment in which the present invention is applied to a gas fan heater with an ion generation function will be described in detail with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the gas fan heater 1 (hot air heater) with an ion generation function of the present embodiment includes a main body case 22, a combustion case 30, and a hot air fan (first fan) 46. And an ion discharge unit 7 and the like. FIG. 1 schematically shows a front view of the main body case 22 with the front plate removed. A first intake port 27 for taking in air for heating and a second intake port 10 for taking in air for blowing ions are formed on the back surface of the main body case 22, and a hot air outlet 48 is formed on the front surface. The ion blower outlet 2 is formed and the outer frame of the gas hot air heater 1 is formed. A filter 32 is provided at the first air inlet 27 and the second air inlet 10. The combustion case 30 has a gas burner 36 inside, and a combustion gas discharge port 30b is formed in the upper part. The hot air fan 46 is provided below the combustion case 30 and communicates with the hot air outlet 48. The first ventilation path in the main body case 22 includes air passages 25, 24, and 29. The air passage 25 is formed between the main body case 22 and the partition plate 31 and cools the main body case 22. The air passage 24 is formed between the partition plate 31 and the flow dividing plate 28. The air passage 29 is formed between the flow dividing plate 28 and the combustion case 30.
[0010]
When the gas burner 36 is ignited, the combustion primary air sucked from a combustion primary air suction port (not shown) and the indoor air are sucked from the first air suction port 27 and the arrow passes through the combustion secondary air suction port 30a. The fuel gas is combusted by the secondary air for combustion supplied as shown in D. The combustion gas generated by the combustion is discharged as indicated by an arrow C from a combustion gas discharge port 30b formed in the upper part of the combustion case 30. During combustion, combustion gas is sucked from the combustion gas discharge port 30b by the rotation of the hot air fan 46. At the same time during combustion, the indoor air is sucked into the air passage 29 as indicated by the arrow B by the rotation of the hot air fan 46. As a result, the combustion gas indicated by arrow C and the air indicated by arrow B are first mixed.
[0011]
At the same time, the indoor air is sucked into the air passage 24 from the first air inlet 27 as indicated by the arrow A by the rotation of the hot air fan 46. As a result, the combustion gas indicated by the arrow C and the air indicated by the arrow A are mixed in the mixing passage 49. That is, the air sucked from the first suction port 27 by the hot air fan 46 moves downward in front of the front plate of the combustion case 30. The hot air fan 46 also sucks the combustion gas discharged from the combustion gas discharge port 30b, and the sucked combustion gas moves downward in front of the front plate of the combustion case 30. While moving downward in front of the front plate of the combustion case 30, the air and the combustion gas are mixed and adjusted to a moderate temperature. Furthermore, the indoor air is sucked from the air passage 25 as indicated by an arrow F by the rotation of the hot air fan 46. The air flows inside the main body case 22 to cool the main body case 22, and finally enters the mixing space 49 from the introduction port 31a and is further mixed with the mixed gas coming from the upstream side. The mixed gas thus mixed becomes hot air having a temperature suitable for heating. The warm air is guided to the warm air outlet 48 along the fan casing 40 by the rotation of the hot air fan 46 and blown out from the hot air outlet 48. This warm air heats the room. The number of revolutions of the hot air fan 46 is controlled according to the heating operation state, and the air volume is increased during rapid heating, and is reduced to a smaller air volume as the set temperature and the room temperature approach.
By the rotation of the hot air fan 46, air necessary for combustion of the gas burner 36 and air necessary for adjusting the temperature of the mixed gas to an appropriate temperature by being mixed with the combustion gas are sucked from the first intake port 27. It blows out from the warm air outlet 48.
[0012]
An ion discharge unit 7 accommodated in the partitioning container 6 is disposed above the air passage 25. The partition container 6 forms a second ventilation path from the second air inlet 10 to the ion outlet 2. A small sirocco fan 8 (second fan) is disposed inside the compartment container 6, and an ion generator 4 is disposed on the side surface.
The compartment container 6, the sirocco fan 8, and the ion generator 4 will be described in more detail with reference to FIG. 3 which is an enlarged front view and FIG. 4 showing a cross section taken along line IV-IV in FIG. The sirocco fan 8 disposed in the compartment container 6 incorporates a small motor 9 at the center, and the sirocco fan 8 is rotated by the rotation of the motor 9 to suck air from the second air inlet 10. It discharges from the ion blower outlet 2.
[0013]
The ion generator 4 is accommodated in the container 6b, is fixed to the side surface of the compartment container 6, and communicates with the second ventilation path downstream of the sirocco fan 8 through the communication port 6c. The ion generator 4 generates both positive ions and negative ions by applying a high voltage from an alternating current power source 56 to the inner electrode 54 and the outer electrode 52 arranged with the cylindrical insulator 50 interposed therebetween. Ions generated by the ion generator 4 are supplied from the air connection port 6 c to the second ventilation path downstream of the sirocco fan 8.
[0014]
An example of the operation status of the gas fan heater 1 is shown in FIG. In FIG. 5, the horizontal axis indicates the time from the start of operation, and the vertical axis indicates the amount of air generated by the rotation of the hot air fan 46 and the sirocco fan 8. Only heating is performed during the first period from the start of operation. In the second period, the operation of the ion generator starts, and both heating and ion supply are performed simultaneously.
When the operation of the gas fan heater 1 is started, the hot air fan 46 rotates and the heating air is taken in from the first air inlet 27. The taken-in air is heated by the gas burner 36 to become warm air, and is discharged from the warm air outlet 48 for heating. At the beginning of operation, since the room temperature is low and rapid heating is performed, the amount of air blown out from the hot air outlet 48 is large. However, when the room temperature reaches a predetermined temperature, the heating operation is switched to weak, and the amount of air blown out from the hot air outlet 48 Is squeezed. Thereafter, the combustion condition of the gas burner 36 is adjusted in order to keep the room temperature constant, and the rotation of the hot air fan 46 is adjusted accordingly, and the amount of air discharged from the hot air outlet 48 varies.
[0015]
In the second period II, the operation of the ion generator 4 starts, the rotation of the sirocco fan 8 starts, and air is taken in from the second air inlet 10. Since positive ions and negative ions are generated from the ion generator 4, air containing positive and negative ions is sent out from the ion outlet 2. At the beginning of the operation of the ion generator 4, the ion concentration in the room is low, and a large amount of air is blown out from the ion outlet 2 to supply a large amount of ions. The air volume for supplying ions is also reduced. Thereafter, in order to keep the ion concentration in the room constant, the amount of generated ions and the amount of blown air are appropriately adjusted.
[0016]
In the present embodiment, the first suction port 27 and the second suction port 10 are independent, and the ventilation path communicating therewith is also independent. Since the ventilation path is independent, the air suction amount of the hot air fan (first fan) 46 and the sirocco fan (second fan) 8 is not affected by the operating conditions of the fans, and is optimal. Air volume and direction can be set easily.
For example, in the period Ia in FIG. 5, the heating is in a weak state, and the hot air fan 46 sucks and discharges a small amount of air in order to supply an appropriate amount of combustion secondary air to the gas burner 36. Since the ion generator 4 is stopped, the sirocco fan 8 is also stopped. In the period IIa in FIG. 5, heating continues to be in a weak operation, whereas the ion generator starts operation, and the sirocco fan 8 blows the maximum amount within the capacity range, and the ion generator 4 A large amount of ions are generated in the room. In this way, the operating condition of the hot air fan 46 can be kept constant from the Ia period to the IIa period when the operating state of the sirocco fan 8 changes. Since the change in the operating condition of the sirocco fan 8 does not affect the amount of heating air, the operating conditions of the hot air fan 46 can be maintained constant before and after the sirocco fan 8 starts operating. Even if the operating condition of the sirocco fan 8 changes while the operating conditions of the hot air fan 46 are kept constant, an appropriate amount of heating air can always be obtained, and the gas burner 36 can be stably maintained at a good air-fuel ratio. Can continue to burn.

Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, although the example which applied this invention to the gas fan heater was demonstrated in the Example, this invention is applicable to the heating machine which uses oil etc. as a fuel. In the present embodiment, the example in which the ion outlet is set on the upper surface of the fan heater has been described. However, the ion outlet can be arranged on the front surface or the side surface by changing the shape of the main body case and the partition container. As a means for generating ions, in addition to a device utilizing discharge, a device utilizing the Leonard effect, a device utilizing spontaneously polarized ore, a device utilizing ceramic, etc. can be used. It is also possible to apply an apparatus that generates only positive ions. As a blowing means, a propeller fan or an air compressor can be used in addition to a sirocco fan.
