  However, the device described in Patent Document 1 is for blowing snow scattered on a windshield or the like of an automobile, or for melting snow, and for melting snow accumulated on a road, a house entrance, a garden, or the like. Is not.

  Since the snow melting device described in Patent Document 2 is a self-propelled large-scale device, for example, it cannot be used to melt snow on a narrow road where a person can walk alone. Only for roads that can run.

  The construction machine described in Patent Document 3 is limited to roads that can be used as in the snow melting device described in Patent Document 2.

  This device was made with such problems in mind, and it is impossible for large devices such as narrow roads, places without roads, house gardens and roads from the road to the entrance to enter. The purpose of the present invention is to provide a portable snow melting machine that can perform snow melting work in various places.

  In order to solve the above-described problems, a portable snow melting machine of the present invention includes a case that can be carried by a person, an air-cooled engine disposed inside the case, a fuel tank that supplies fuel to the air-cooled engine, and an air-cooled engine And a fan for taking outside air into the case from the intake formed in the case, and discharging hot air heated by the air-cooled engine to the outside from the discharge port formed in the case, and inside the case And a flow path forming plate that forms a flow path of air from the intake port to the discharge port.

  The snow melting machine of the present invention is used, for example, by humans, and discharges warm air obtained by heating the outside air taken inside the case with an air-cooled engine to the outside of the case, and uses this warm air for melting snow. To do.

  According to the sixth aspect of the present invention, warmer hot air can be obtained, and the snow melting efficiency per air volume is improved.

  According to the invention described in claim 7, the rotation speed of the fan (that is, the amount of hot air) and the temperature of the hot air can be adjusted by operating the accelerator bar.

  Hereinafter, the present invention will be described in more detail with reference to embodiments.

  FIG. 1 is an external perspective view of a portable snow melting machine according to an embodiment, FIG. 2 is a front view of the snow melting machine viewed from the inside of the case 1, and FIG. 2 is a front view of the snow melting machine viewed from the outside of the case 1. As shown in FIG.

  This snow melting machine is used by a person on the back, and includes a rectangular parallelepiped case 1, and a shoulder belt 2 is attached to the inside of the case 1 (the side that contacts the back when it is carried). An intake 5 for taking outside air into the inside of the case 1 is formed at the upper right of the outside of the case 1, and heated by air-cooled engines 10 and 11 (see FIGS. 4 and 5) at the lower right of the inside of the case 1. A discharge port 6 (see FIG. 8) for discharging the warm air to the outside of the case 1 is formed. A hose 95 that guides warm air is connected to the discharge port 6.

  Further, a fuel tank 20 for supplying fuel to the air-cooled engines 10 and 11 is provided at the upper part of the case 1, and the spark plugs 12 and 13 for igniting the air-fuel mixture in the air-cooled engines 10 and 11 are provided on the side of the case 1. A battery 15 is attached. In addition, an elastic heat-resistant mat 8 is attached to the entire inner surface of the case 1 in order to prevent the heat of the case 1 from being transmitted to the back and to obtain cushioning properties that soften the case 1 against the back. Yes.

  FIG. 4 is a schematic plan view (schematic top view) showing the inside of the case 1 of this snow melting machine, FIG. 5 is a schematic front view of the outside showing the inside of the case 1, and FIG. 5 is a schematic side view showing the inside of the case 1 It is shown in FIG.

  Inside the case 1, two two-cycle engines 10 and 11 are juxtaposed on the left and right sides of the case 1 as air-cooled engines. As described above, each of the two-cycle engines 10 and 11 has a weight of 10 kg or less, and the displacement is not particularly limited. Spark plugs 12, 13 are attached to the heads of the engines 10, 11, and the spark plugs 12, 13 appear at the top of the case 1. The spark plugs 12 and 13 are connected to a battery 15 attached to the side of the case 1 by, for example, a cable (not shown).

  As described above, the fuel of the two-cycle engines 10 and 11 is a mixed oil obtained by mixing gasoline and engine oil. The mixed oil is accommodated in a fuel tank 20 provided in the upper part of the case 1. Although not shown in the drawings, the fuel in the fuel tank 20 is piped so as to be supplied to the two-cycle engines 10 and 11 naturally (by dropping).

  The two-cycle engines 10 and 11 are fixed by support rods 30 and 31 so as not to move back and forth and left and right inside the case 1. Further, the exhaust gas of the two-cycle engines 10 and 11 is exhausted to the outside of the case 1 (behind the human side) by an exhaust pipe (built-in muffler) 90 disposed at the bottom of the case 1.

  Taking the two-cycle engine 10 as a power source, outside air is taken into the case 1 from the intake 5 of the case 1, and warm air heated by the two-cycle engines 10 and 11 is discharged from the outlet 6 of the case 1 to the outside of the case 1. A fan 40 for discharging is provided. The fan 40 is rotatably supported on the upper part of the two-cycle engine 10 by a support shaft 41, and a sprocket 42 is attached to the outside of the fan 40 of the support shaft 41.

  A clutch plate 50 is disposed below the two-cycle engine 10 corresponding to the fan 40. The clutch plate 50 is rotatably supported on the engine 10 by a support shaft 51 so as to rotate in conjunction with the operation of the two-cycle engine 10. That is, the support shaft 51 is connected to a known power conversion mechanism (for example, composed of a connecting rod and a crankshaft) that converts the reciprocating motion of the piston of the engine 10 into a rotational motion, and the clutch plate 50 is operated when the engine 10 is operated. It is designed to rotate.

  Another clutch plate 55 is arranged to face the clutch plate 50. The clutch plate 55 is rotatably attached to one end portion of the support shaft 56, and a sprocket 57 is attached to the other end portion of the support shaft 56. Although not shown in the drawing, the clutch plate 55, the support shaft 56, and the sprocket 57 are supported so as to come into contact with or separate from the clutch plate 50. That is, the clutch plate 55 can be switched between a state in which the clutch plate 55 is in contact with the clutch plate 50 and a state in which the clutch plate 55 is separated from the clutch plate 50. These two states are configured to be switched by operating a fan clutch bar 80 provided in the case 1.

  The chain 45 is hung on the sprocket 42 on the fan 40 side and the sprocket 57 on the clutch plate 55 side, and the rotation of the clutch plate 50 is transmitted to the fan 40 via the clutch plate 55 and the chain 45.

  When the fan clutch bar 80 is operated and the clutch plate 55 is brought into contact with the clutch plate 50, the fan 40 rotates, and the outside air is taken into the case 1 from the intake port 5 of the case 1 and passes through the flow path described later. Thus, the warm air heated by the two-cycle engines 10 and 11 is discharged from the discharge port 6 of the case 1 to the outside of the case 1. When the fan clutch bar 80 is operated and the clutch plate 55 is separated from the clutch plate 50, the rotation of the fan 40 is stopped and the discharge of warm air is stopped. By providing the fan clutch bar 80 in this manner, the fan 40 can be rotated only when necessary to obtain hot air.

  The case 1 is provided with an accelerator bar 81 in addition to the fan clutch bar 80. By operating the accelerator bar 81, the rotational speeds of the two-cycle engines 10 and 11 can be controlled. That is, when the rotation speed of the engine 10 is increased by operating the accelerator bar 81, the rotation speed of the fan 40 is also increased, the amount of hot air is increased, and the temperature of the hot air is increased. On the contrary, when the rotation speed of the engine 10 is decreased by operating the accelerator bar 81, the rotation speed of the fan 40 is also decreased, the amount of hot air is decreased, and the temperature of the hot air is decreased. By providing the accelerator bar 81 in this manner, the rotation speed (that is, the amount of hot air) of the fan 40 and the temperature of the hot air can be adjusted.

  Further, the case 1 is provided with a starter button 82, and when the starter button 82 is pressed, the two-cycle engines 10 and 11 are started.

  Next, with respect to the air flow path from the intake port 5 to the discharge port 6 of the case 1 in FIG. 7 (internal schematic perspective view of the case 1 showing only the flow path forming plate), FIG. A description will be given with reference to FIG. 9 (a schematic side view of the inside of the case 1 showing the flow of air) and FIG. 9 (a schematic front view of the outside of the case 1 showing only the path forming plate).

  As shown in FIGS. 4 and 5, two flow path forming plates 60, 61 in the vertical direction that divide the internal space into three chambers 100, 101, 102 in the left-right direction are fixed inside the case 1. . Although the two-cycle engines 10 and 11 are not shown in FIGS. 7 and 8, the flow path forming plates 60 and 61 are in close contact with the side walls of the two-cycle engines 10 and 11. Reference numeral 102 denotes a space extending in the vertical direction. The flow path forming plate 60 has a through hole 60a communicating with the chambers 100 and 101 in the lower part thereof, and the flow path forming plate 61 has a through hole 61a communicating with the chambers 101 and 102 in the upper part thereof (see FIG. 7). ).

  Further, as shown in FIGS. 7 to 9, in the case 1, four flow path forming plates 70 in the left-right direction that partition each chamber 100, 101, 102 partially into five chambers in the vertical direction, 71, 72, 73 are fixed. As is apparent from the figure, the flow path forming plates 70 to 73 are all in close contact with the inner surface of the side wall of the case 1 in the left-right direction of the case 1. The flow path forming plates 70 and 72 are in close contact with the inner surface of the outer wall of the case 1 in the front-rear direction of the case 1, but are not in close contact with the inner surface of the inner wall and extend to the middle of the elastic heat-resistant mat 8 side. ing. The flow path forming plates 71 and 73 are in close contact with the inner surface of the inner wall of the case 1 in the front-rear direction of the case 1, but are not in close contact with the inner surface of the outer wall and extend partway on the intake 5 side. In other words, the gaps are alternately formed in the chambers 100, 101, 102 in the front-rear direction by the flow path forming plates 70-73.

  Although the two-cycle engines 10 and 11 are not shown in FIGS. 7 and 8, the flow-path forming plates 70 to 73 are formed on the side walls of the two-cycle engines 10 and 11, similarly to the flow-path forming plates 60 and 61. Close.

  The flow path forming plates 60 and 61 and the flow path forming plates 70 to 73 form air flow paths that circulate around the two-cycle engines 10 and 11 in the internal space of the case 1. As shown by the arrow lines in FIGS. 7 to 9, the outside air enters the inside of the case 1 from the intake 5 of the case 1, and first flows in order from the uppermost chamber to the lowermost chamber of the chamber 100. The chamber 101 enters the chamber 101 through the through hole 60a, flows in order from the lowermost chamber of the chamber 101 to the uppermost chamber, enters the chamber 102 from the through hole 61a of the flow path forming plate 61, flows in order from the uppermost chamber of the chamber 102 to the lowermost chamber, It is discharged from the discharge port 6 to the outside of the case 1 and ejected through the hose 95 in the intended direction. The outside air is heated by the two-cycle engines 10 and 11 in the process of flowing through the flow path to become warm air.

  The portable snow melting machine configured as described above is used by a human being carried on the shoulder strap 2 of the case 1. When using warm air for melting snow, the starter button 82 is pressed to start the two-cycle engines 10 and 11. Then, since the clutch plate 50 is rotated by the operation of the two-cycle engine 10, when the fan clutch bar 80 is operated to connect the clutch plate 55 to the clutch plate 50, the fan 40 rotates. Due to the rotation of the fan 40, outside air enters the inside of the case 1 from the intake 5 of the case 1 and is heated by the two-cycle engines 10 and 11 in the process of flowing through the flow path as described above, and this hot air is The gas is discharged from the discharge port 6 of the case 1 to the outside of the case 1 and is further ejected from the tip of the hose 95.

  When the use of the hot air is stopped, the fan clutch bar 80 is operated to release the clutch plate 55 from the clutch plate 50, so that the fan 40 stops rotating and the hot air blowing stops.

  The air volume and temperature of the warm air can be adjusted by operating the accelerator bar 81 and changing the rotational speed of the engine 10 to high or low as described above.

  This portable snow melter can be used on the back of humans, so it is impossible for large devices such as narrow roads, roads without roads, house gardens, and roads to the entrance to enter. Snow melting work can be done easily in any place.

  Further, since the internal space of the case 1 is partitioned vertically and horizontally by the flow path forming plates 60 and 61 and the flow path forming plates 70 to 73 so that the outside air circulates around the two-cycle engines 10 and 11, The outside air can be efficiently heated by the heat of the engines 10 and 11.

  In addition, since the two two-cycle engines 10 and 11 are mounted, it is possible to obtain hot air at a higher temperature than in the case of one, and the snow melting efficiency per air volume is improved.

  The portable snow melting machine is an example, and various modifications can be made. For example, in the above embodiment, the rotation of the clutch plate 50 is transmitted to the fan 40 by the chain 45 and the sprockets 42 and 57, but a belt and a pulley may be used.

  In addition, when the starter button 82 is pressed, instead of starting the two two-cycle engines 10 and 11 at the same time, an operating two-cycle engine may be selected. For example, only the two-cycle engine 10 may be operated first, and the two-cycle engine 11 may be operated when raising the temperature of the hot air.

  Alternatively, in the above embodiment, the rotation of the fan 40 is controlled by operating the fan clutch bar 80. However, in the case of a simpler structure, the fan 40 is directly connected to the power conversion mechanism, and the two-cycle engine 10 The fan 40 may be rotated simultaneously with the operation.
