Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick type oil combustion machine using a Stirling engine, and its main purpose is to generate a convection fan using its own combustion heat without using any household AC power source. The purpose of this system is to rotate the system to enable not only radiant heating but also hot air heating, thereby leveling out the temperature distribution in the room.

Conventional wick-type oil-burning machines equipped with reflectors had the disadvantage that only the front part was warm due to radiation, and warm air was concentrated only in the upper part of the room, making it impossible to provide comfortable heating.

In addition, in order to eliminate this drawback, if a convection fan 19 is attached to the upper part of the combustion tube 1 on the back of the casing 37 of the wick type oil combustion machine as shown in Fig. 4, the air to the burner section at the bottom of the combustion tube 1 will be Inflow is likely to occur, making it difficult to maintain stable combustion. Furthermore, this combustion machine has a convection fan 1.
A household AC power source was required to turn the 9, making it impossible to use it in places without electrical outlets.

Generally speaking, oil combustion machines dry the air through combustion, so a steam generator is often added, but this equipment is relatively expensive and is therefore not usually attached to the combustion machine.

Therefore, the present invention aims to solve the above-mentioned drawbacks at once and achieve the above-mentioned object, and furthermore, it is an object of the present invention to make it possible to attach a steam generator at a low cost.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In addition, FIG. 1 is a perspective view of a core up-and-down oil combustion machine showing one embodiment of the present invention, and FIG. 2 is a cross-sectional view of the main part of FIG. 1 as seen from the side.
FIG. 3 is a diagram showing the driving portion of the convection fan.

First, referring to FIG. 1, 37 is a casing, and a machine room 39 has a built-in burner section (not shown).
The reflective plate 10 is attached to the back surface, and the warm air blowing device 38 is attached to the upper surface.

Also, the top plate 11 is on the top side of the casing 37, the two pillars 12 and 13 are on the front side, and the back plate 3 is on the back side.
1. The lower surface side is a machine room cover 40. Further, an oil tank 3 is disposed behind the casing 37, and a machine room 39 in which the casing 37 is placed and the oil tank 3 are placed on a pedestal 2 and communicated through an oil filler port 4. Now, warm air blowing device 3
A combustion tube 1 extending from a machine room cover 40 is disposed below 8, and a heat radiation net 33 is placed over the combustion tube 1.
It almost faces the heating part 23 of the hot gas reciprocating engine 21 built into the engine 8. Of course, the heat radiation net 33 also faces the top plate 11. Further, the wick adjustment knob 5 and the ignition button 6 are exposed from the machine room 39, and since the combustion tube knob 7 extends near the wick adjustment knob 5, the wick adjustment knob 5 is turned in the "combustion" direction. By turning the heater to pull up the wick and pressing the ignition button 6, the built-in dry cell battery makes the heater red-hot and ignition can be performed. By rotating the combustion tube knob 7, the flame can be transferred all around the wick. During combustion, radiant heat is transmitted to the front of the casing by the reflector 10. Furthermore, since a stand 15 on which a kettle or the like can be hung is formed at the front center of the top plate 11, it can be used for purposes other than heating, which is preferable. Of course, guards 14 are provided on both sides and the front of the casing 37 to prevent burns.
is attached. Now, referring to FIG. 2, the hot air blowing device 38 will be explained.
Front panel 1 equipped with hot air outlet 20 on the front side of
6 is fitted into the front panel 16, and a convection fan 19 is positioned in the front panel 16 near the hot air outlet 20. An air supply port 32 is formed in the back plate 31, and by rotating the convection fan 19, air can be discharged from the hot air outlet 20.

This convection fan 19 is a Stirling engine 21
The Stirling engine 21 is driven by absorbing heat from the heating section 23 as described above.

By the way, the Stirling engine 21 shown in FIG. 3 has a displacer piston 41 and a power piston 42 built into the cylinder 24, as is well known.
The power piston 42 is caused to reciprocate by subjecting the working gas to isothermal compression, isovolumic heating, isothermal expansion, and isovolume cooling.
It is cooled by the water that collects in it. Note that the displacer piston 41 transfers the working gas to the regenerator 25.
It has the function of moving from the cooling section side to the heating section side via.

Further, the storage tank 43 is always filled with water because it is communicated with a water tank 28 supported by a mounting plate 44 extending from the top of the Stirling engine 21 through a connecting pipe 30. This water then cools the cooling section 22 of the Stirling engine 21.

At the same time, the water turns into steam, and the storage tank 43
The steam is discharged from a steam generator 29 connected to the top of the steam generator. Since the other end of the steam generator 29 is positioned at the steam outlet 34 adjacent to the hot air outlet 20, the steam is discharged to the front side of the casing 37 together with the hot air.

By the way, the water tank 28 is made of transparent or translucent synthetic resin, and the water level in the water tank 28 can be checked at all times through a water level confirmation window 36 provided on the side of the casing 17 of the hot air blowing device 38. ing. Therefore, when the water in the water tank 28 decreases, the lid 45 can be opened, the water tank 28 can be removed from the connecting pipe 30, and water can be supplied.

Now, one output shaft 26 of the Stirling engine 21
As described above, the convection fan 19 is fixed to the other output shaft 27.
Connect the starting motor 35 of No. 9. The starting motor 35 is connected in series to an operation switch 18 provided on the casing 17 and an ignition battery (not shown), and is driven mainly at the start of combustion.

Note that the air sucked in by the convection fan 19 from the air supply port 32 of the back plate 31 is mixed with the high-temperature combustion exhaust gas C discharged from the combustion tube 1, and is blown into the room as warm air as shown by arrow B. .

Next, the operation of the above embodiment will be explained.

First, ignite it by a series of ignition operations as described above,
When the heat dissipation net 33 of the combustion tube 1 becomes red hot, the heat is radiated as shown by arrow A by the reflector plate 10 on the back surface, resulting in so-called radiant heating.

In addition, as mentioned above, only the front part of the room is warm, and the warm air gathers in the upper part of the room, making it impossible to achieve uniform heating. However, when the operation switch 18 on the casing 17 is operated, the starting motor 35 rotates the convection fan 19, and air is supplied from the hot air outlet 20, and the high-temperature combustion exhaust gas discharged from the combustion tube 1 is heated. Because it is mixed,
This air can be supplied indoors as warm air. This also suppresses the concentration of warm air at the start of combustion.

On the other hand, when hot air is blown out, the heating section 23 of the Stirling engine 21 is disposed above the combustion tube 1, so it is heated by the red-hot heat dissipation net 33.
On the other hand, since the storage tank 43 of the Stirling engine 21 is filled with water, the cooling section 22 is cooled, and a temperature difference gradually arises between the heating section and the cooling section of the Stirling engine 21. As a result, the working gas within the engine repeats a closed cycle of isothermal compression, isovolumic heating, isothermal expansion, and isovolumic cooling, and the crank mechanism 46 within the engine rotates the output shafts 26, 27.
That is, after a certain period of time has passed after ignition, an appropriate temperature difference is secured between the heating section and the cooling section, and the starting motor 3
The output shaft 26 can be rotated without any force from 5, and the convection fan 19 can be rotated.If the operating switch 18 is turned off at this point, the hot air can be turned off without consuming the built-in battery. can be supplied.

On the other hand, the temperature of the water in the storage tank 43 rises due to heat transfer from the heating section 23, and eventually steam is generated, and this steam passes through the steam generator 29 and is ejected from the steam outlet 34. As a result, the convection fan 19 can supply water vapor into the room at the same time as hot air. That is, it is possible to appropriately humidify the room without separately providing a heater using an ultrasonic type or the like.

The present invention has the configuration and operation as described above, and the main effects thereof are listed below.

Comfortable heating can be achieved not only by radiant heating using a reflector but also by hot air heating using a convection fan.

Since it has a built-in Stirling engine, the convection fan can be rotated after a certain period of time (1 to 2 minutes) by simply using its own combustion without requiring a power source such as a dry battery. Therefore, it is extremely energy-saving and does not require any household AC power source as in the past, making it cordless and portable, allowing it to be used even in rooms without electrical outlets.

Since the interior of the room is humidified using water vapor produced by evaporation of water in the storage tank of the Stirling engine, there is no need for a separate humidifier or the like, which was conventionally required.
