In order to do so, the inside of the greenhouse is piped, and the exhaust heat-resistant fan 31 is installed before reaching the outside in order to melt snow accumulated around the greenhouse.

  With such a configuration, the heated exhaust gas passing through the exhaust pipe 3 functions as a heat source for warming the air inside the greenhouse, and the heated exhaust gas exhausted to the outside of the greenhouse is It functions to blow off the snow that has accumulated around it by wind pressure and to melt it. Since such equipment can be operated continuously for a long period of time due to the effect of the present invention, the inside of the greenhouse is steadily warmed and the snow around the greenhouse is melted or against new snowfall. It is suitable for applications that suppress snow accumulation.

  Furthermore, as shown in FIG. 11, an exhaust fan 32 intended to generate a negative pressure due to the venturi effect may be installed instead of installing a heat-resistant fan that exhausts exhaust gas heated directly in the middle of the exhaust pipe. it can. Such a configuration makes it possible to exhaust air at a higher wind pressure than in the configuration according to FIG. 10, so that the effect of blowing snow accumulated around the greenhouse with the wind pressure can be expected more.

  FIG. 12 is a view showing another example of a pellet stove burner according to an example of a preferred embodiment of the present invention.

  As shown in FIG. 12, the fuel support plate 18 having a mesh structure is supported by the fuel support plate installation frame 181, and the pellet fuel 112 burns on the upper surface of the fuel support plate main body 18a. Specifically, for example, as shown in FIG. 12, the fuel support plate 18 is composed of a fuel support plate body 18a with a rectangular mesh, and a diffusion prevention wall portion 18b with a cylindrical mesh.

At this time, the distance between the lower end of the burner (burner portion) 13 and the fuel support plate body 18a is appropriately set according to the shape and size of the pellet fuel to be used, and is preferably about 15 mm to 50 mm.

  Here, the distance between the lower end of the burner cover 14 and the burner (burner part) 13 and the fuel support plate main body 18a, the fineness of the mesh structure, etc. are appropriately determined depending on the shape and size of the pellet fuel 112 to be used. adjust. Preferably, the substantially cylindrical pellet fuel 112 having a diameter of 3 mm or more and 8 mm or less and a length of 5 mm or more and 30 mm or less is further separated by a distance of 15 mm or more and 50 mm or less from the lower end of the second container (burner cover 14). It is preferable that the fuel support plate 18 is provided at the position, and the fineness of the mesh structure is 5 mm or more and 10 mm or less for the fuel support plate body 18a, and the diffusion prevention wall portion 18b is 5 mm or more and 7 mm or less. The height of the diffusion prevention wall portion 18b is about 20 mm.

  Further, as shown in FIG. 12, in the vicinity of the upper surface of the fuel support plate main body 18a, more specifically, between the upper surface of the fuel support plate main body 18a and the lower ends of the burner (burner portion) 13 and the burner cover 14. Further, the agitation member 17 for agitating the fused pellet fuel 112 or the ash produced by burning the pellet fuel 112 is further provided.

  Here, the agitating member 17 is a substantially cross-shaped agitating portion (rod-like shape) that rotates about the substantially center of the cylinder forming the burner (burner portion) 13 in the axial direction of the cylinder forming the burner (burner portion) 13. Member) 173, a first rotating shaft portion 171 for rotating the stirring portion (rod-like member) 173, a second rotating shaft portion 172 linked to the first rotating shaft portion 171, and a second rotating shaft portion. And at least a handle 175 for rotating. The stirring unit (rod-like member) 173 is not limited to a substantially cross shape, and various shapes can be adopted as long as the technical idea of the present invention is followed. Specifically, for example, those forming a T-shape with the first rotating shaft portion, propellers, etc. may be employed.

  Further, the first rotating shaft portion 171 and the second rotating shaft portion 172 are linked substantially at right angles by the bevel-shaped gears 174a and 174b and rotate in conjunction with each other. By providing such a structure, when the user rotates the handle 175, the second rotating shaft portion 172 rotates, and the first rotating shaft portion 171 linked at a substantially right angle by the umbrella gears 174a and 174b. The agitating portion (rod-like member) 173 in the vicinity of the upper surface of the fuel support plate main body 18a is rotated and finally the pellet fuel 112 and the like can be agitated. Although not shown, a motor that operates at a predetermined time interval may be installed instead of the handle 175 so that the user can set and use the time interval as appropriate.

  As a result, the pellet fuel 112 preferably stays in the vicinity of the upper surface of the fuel support plate main body 18a, and the clogging of the fuel support plate main body 18a is suppressed by periodically rotating the stirring portion (rod-like member) 173. Thus, it is possible to realize suitable combustion for a long time. Furthermore, if a motor that operates at predetermined time intervals is used, unmanned operation can be performed for a long time.

  Further, the pellet tank (container part) 11 is further introduced into the pellet tank (container part) 11 near the upper end of the pellet tank (container part) 11 with outside air introduced from the stand (leg part) 15 through the side opening 121 of the pellet tank cover. An opening 124 is provided.

  Furthermore, the pellet tank (container container) 11 is provided with an intake fan 154 (see FIG. 15) that forcibly introduces outside air into the stand (leg part) 15 at the air inlet 151 of the stand (leg part) 15. Can also be combusted more suitably by introducing outside air.

  When the intake fan 154 as described above is used, the pellet tank lid (lid portion) 16 floats from the pellet tank (container container portion) 11 and the pellet tank cover (container cover) 12, and the pellet tank. It is preferable to provide a lock mechanism 191 so that the outside air introduced into the (container container) 11 does not leak.

  Here, as long as the specifications of the intake fan 154 and the lock mechanism 191 are in accordance with the principle of the present invention, known ones may be appropriately selected.

  13 and 14 are perspective views showing the external appearance of the pellet stove burner shown in FIG.

  The fuel support plate 18 can be installed by being placed on the fuel support plate installation frame 181 and is detachable. By adopting such a configuration, the fineness of the mesh structure of the fuel support plate 18 is appropriately selected according to the shape and size of the pellet fuel 112, periodically disassembled and cleaned, or fuel that has deteriorated due to use. The support plate 18 can be replaced with a new one.

  FIG. 15 is a diagram illustrating the intake fan 154 described in FIG. As shown in the figure, by installing an intake fan 154 in the vicinity of the air inlet 151 of the stand (leg part) 15, it is possible to forcibly introduce outside air into the stand (leg part) 15. It is more preferable to provide a flow rate adjusting plate 1541 for appropriately adjusting the amount of air introduced.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
