[0010] Hereinafter, the mode for carrying out the present invention will be described in detail based on examples. EXAMPLES

[0011] First, a first embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is an overall perspective view, and Figure 2(A) is a side view. Figure 2(B) is a detailed view of the heating device. In these figures, a vehicle heating device 10 of this embodiment is configured such that a circulation device 100 is provided inside a container 12 large enough to store a car, truck, etc., and a burner device 200 is provided outside the container 12. Doors 22, 32 that can be opened and closed are provided at the entrance 20 and exit 30 of the container 12, and slopes 24, 34 are provided, respectively, to facilitate the loading and unloading of vehicles.

[0012] Of these, the circulation device 100 is mainly composed of a circulation duct 110 provided on the ceiling of the container 12. The circulation duct 110 is provided corresponding to the position of the burner device 200, and is equipped with branch ducts 112, 114 extending toward the inlet and outlet of the container 12. A plurality of blow-out ports 120 and a plurality of air supply hoses 130 are provided at appropriate intervals on the side surfaces of these branch ducts 112, 114.

[0013] An air intake 140 is provided on the underside of the container 12 in correspondence with the position of the burner device 200, and a filter for removing dust and the like is provided as necessary. Meanwhile, a required number of circulators 142 for circulating air inside the container 12 are provided at appropriate positions on the ceiling side of the container 12, and a required number of temperature sensors 144 are provided at appropriate positions on the inner side surface of the container 12.

[0014] Next, as shown in FIG. 2(B), the burner device 200 includes a burner 210 that burns gaseous fuel or liquid fuel, and the heat exchanger 212 is heated by the burner 210. Smoke generated after combustion by the burner 210 is discharged to the outside air through a chimney 214. Meanwhile, the above-mentioned air intake 140 of the container 12 serves as the inlet of an air intake duct 220, and the air taken in through the air intake duct 220 is indirectly heated by the heat exchanger 212 and sent to the circulation duct 110 in the container 12. The circulation of air in the heat exchanger 212 is performed by a sirocco fan (or a propeller fan) 222. For example, when the heat exchanger 212 is a cylinder, the inside of the cylinder is heated by the flame of the burner 210, and the air comes into contact with the outside of the cylinder, thereby indirectly heating the air. In this manner, in this embodiment, the air is not directly heated by the flame of the burner 210 but is indirectly heated via the heat exchanger 212 .

[0015] The above-mentioned air supply hose 130 is laid along the side (wall) from the ceiling of the container 12, and the part beyond the side is bellows-shaped and can be bent and stretched freely. The tip opening of the air supply hose 130 is installed in parts of the automobile W to be heated that are relatively hard to heat, such as the engine room, under the seat, trunk room, etc., and supplies heated air to these parts. Furthermore, temperature sensors 146 are installed in these parts that are relatively hard to heat (see FIG. 2(B)), which detect the degree of temperature rise and notify the control panel 40 via wireless LAN or the like (see FIG. 2(A)).

[0016] The control panel 40 starts and stops the combustion of the burner 210 and turns on and off the operation of each part, and also receives the detection results of the temperature sensors 144, 146 by wire or wirelessly to control the operation of each part. Operation is performed automatically using a computer or sequencer.

[0017] Next, the overall operation of this embodiment will be described. The automobile W to be heated is placed inside the container 12 with the door 22 of the entrance 20 open. Then, the air intake hose 130 is installed so that its tip opening faces the engine room, under the seat, and trunk room of the automobile W, which are difficult to heat up. In addition, a temperature sensor 146 is installed at a necessary location of the automobile W. The temperature sensor 146 is also installed in a part of the automobile W that is relatively difficult to heat up. Once the installation is completed, the doors 22, 32 of the entrance 20 and exit 30 of the container 12 are closed.

[0018] Next, the heating temperature and heating time are set by the control panel 40, and each unit is turned ON to start driving. As a result, the burner 210 is ignited and the heat exchanger 212 is heated, and the sirocco fan 222 is driven to circulate air from the burner device 200 → the circulation device 100 → the container 12 → the burner device 200. Also, within the container 12, air is circulated by the circulator 142. As a result, the container 12 becomes filled with heated air, and the temperature inside the container rises overall.

[0019] The temperature inside container 12 is detected by temperature sensor 144, and the temperature of the engine room of automobile W is detected by temperature sensor 146. Control panel 40 adjusts the degree of combustion by burner 210 and controls the air temperature according to the detection results of these temperature sensors 144, 146. For example, when exterminating stink bugs, heating is performed at a temperature of 61° C. or higher for 10 minutes, or at 57° C. or higher for 30 minutes.

[0020] In this embodiment, heated air is sent to the engine room of the automobile W, which is difficult to warm up, by the air supply hose 130, and the temperature rises efficiently. This makes it possible to uniformly increase the temperature of each part of the automobile W, and shortens the work time. In addition, in this embodiment, the air is not directly heated by the flame of the burner 210, but is heated indirectly via the heat exchanger 212. Therefore, neither the flame of the burner 210 nor the heated air in the cylinder reaches the container 12 through the circulation duct 110, and damage to the automobile W and each device in the container 12 due to the flame can be prevented. EXAMPLES

[0021] Next, a second embodiment of the present invention will be described with reference to Figs. 3 and 4. In the first embodiment described above, heated air is supplied to the inside of the container 12 from the ceiling side, but in this embodiment, heated air is supplied to the inside of the container 52 from the floor side. Fig. 3 shows the vehicle heating device 50 of this embodiment as seen from the front exit side. As shown in this figure, in this embodiment, a circulation device 500 is provided inside the container 52, and a burner device 600 is provided outside the container 52. In this embodiment, a burner device 600 is provided on each side of the container 52, and a circulation device 500 is provided corresponding to each burner device 600. The entrance and exit doors and slopes of the container 52 are the same as those of the above-mentioned embodiment (not shown).

[0022] Of these, the circulation device 500 is mainly composed of a circulation duct 510 provided from the ceiling to the side of the container 52. A plurality of air intake holes 512 are provided on the ceiling side of the circulation duct 510 so that the air inside the storage is sucked into the duct. The air intake holes 512 are provided with a filter (not shown) for removing dust and the like as necessary. The circulation duct 510 passes from the ceiling side through the side of the container 52 and is connected to an air supply duct 550 provided on the underside of the container 52. The air supply duct 550 is provided from the inlet to the outlet of the container 52, and air heated by a burner device 600 is supplied to the air supply duct 550.

[0023] The air intake duct 550 is provided with a plurality of air outlets 520 at appropriate intervals, through which heated air is supplied into the compartment from the underside of the container 52. The air intake duct 550 is also connected with a plurality of air intake hoses 530 at appropriate intervals, through which heated air is also supplied. The air intake hose 530 is bellows-shaped and can be bent and stretched freely, as in the above embodiment, and is used to supply heated air to the engine rudder and other parts of the automobile W that are relatively difficult to heat up, and temperature sensors are also installed at these locations (not shown).

[0024] 4 shows the operation of circulation device 500 as viewed from the side, in which heated air is supplied into the refrigerator from air outlet 520 on the lower side of container 52 and air supply hose 530, and is taken in through air intake hole 512 on the ceiling side. Thus, according to this embodiment, heated air is circulated from the bottom to the top of the refrigerator, utilizing the principle that heated air rises.

[0025] A burner device 600 is provided at the lower part of the side of circulation duct 510. Burner device 600 is composed of burner 610, a heat exchanger 612, a chimney 614, and a sirocco fan 622. Sirocco fan 622 supplies heated air to the above-mentioned air supply duct 550. In this embodiment, air is indirectly heated by heat exchanger 612, as in the above-mentioned embodiments.

[0026] As in the previous embodiment, a circulator and a temperature sensor are provided as necessary inside the container 52. The same applies to a control panel (neither of which are shown).

[0027] The basic operation of this embodiment is similar to that of the above-mentioned embodiment, but since two burner devices 600 are provided, sufficient heated air can be supplied even to a large vehicle such as a truck WT. Also, the heated air circulates from the lower side to the upper side of the container 52, which is the opposite of the above-mentioned embodiment. This embodiment can also provide the same effects as the above-mentioned embodiment.

[0028] Other Examples The present invention is not limited to the above-described examples, and various modifications can be made without departing from the spirit and scope of the present invention. For example, the following modifications are also included. (1) In the above embodiment, the temperature sensor 146 is installed in a part of the vehicle that is relatively difficult to heat up, such as the engine room, but similar to the above-mentioned background art, it may be installed in a part that is relatively easy to heat up, such as the upper part of the seat. In this way, by detecting the temperature of the high temperature part and the low temperature part of the vehicle, it is possible to perform the necessary heating process while preventing damage to the vehicle due to heat. (2) The shapes and dimensions of each part shown in the above embodiment are merely examples and may be modified as necessary. For example, a container may house multiple vehicles in series or in parallel. Similarly, the shapes and arrangement of the ducts, the shapes of the air outlets 120 and 520, etc. may be modified as necessary. (3) In the above embodiment, the case where high-temperature air is supplied to an automobile for the purpose of pest control is shown, but the present invention does not prevent the application of the present invention to purposes other than pest control. In addition, the object to be heated is not limited to the automobile, but may be applied to vehicle parts and accessories, various other devices or equipment, materials, products, etc. [Industrial Applicability]

[0029] According to the present invention, by heating areas that are difficult to heat using an air supply hose, it is possible to make the temperature rise of the heated object uniform, and by indirectly heating the air, it is possible to prevent damage to the heated object by the burner flame, making it suitable for applications such as heating treatment of automobiles for pest control.
