Located on the outer peripheral side of the side wall. In this state, since the filler opening lid 3 does not open or close, the tank storage chamber 7 has a structure in which the cartridge tank 2 cannot be refueled. Thus, if the cartridge tank 2 is not taken out from the tank storage chamber 7, refueling cannot be performed, and a safe heating device can be used. When the cartridge tank 2 is taken out from the tank storage chamber 7, the cartridge tank 2 is pushed upward. The supplied filler lid 3 rotates in the horizontal axis at the shaft portion 12. At this time, the abutted portion 3b of the fuel filler lid 3 turns around below the abutting portion 13 of the cartridge tank 2, and this abutting portion 13 functions as a stopper for restricting the rotation of the fuel filler lid 3. . Thus, when the cartridge tank 2 is stored in the tank storage chamber 7, the fuel filler lid 3 is always closed. Accordingly, the cartridge tank 2 cannot be stored in the tank storage chamber 7 in a state in which the filler opening lid 3 is opened.

By forming the heating device of the present embodiment as described above, the following operations and effects can be achieved.
When the cartridge tank 2 is stored in the tank storage chamber 7 of the heating main body 1 as described above, the fuel filler lid 3 is restricted by the contact portion of the cartridge tank 2 and closed in a non-rotatable state (see FIG. 1 (b)). As a result, the fuel filler port 5 is not exposed to the outside and cannot be refueled as it is, so that kerosene cannot be directly fed to the heating body 1. Therefore, the danger of refueling while using the heating device is eliminated, and an accident such as a fire due to an ignition can be prevented. Further, when the cartridge tank 2 is taken out and refueled, since the support leg 15 is provided at the bottom of the cartridge tank 2, the cartridge tank 2 is erected with the taken-out oil filler port 5 facing upward. can do. Further, when the cartridge tank 2 is stored in the tank storage chamber 7, the cartridge tank 2 unexpectedly hits the contacted portion 3b of the filler opening lid 3, the filler opening lid 3 falls down, and the filler opening closing portion 3a becomes the cartridge. May fall to the side. On the other hand, the oil supply port closing part 3 a is received by the restriction part 31 of the cartridge tank 2, so that the oil supply port closing part 3 a does not enter below the contact part 13 of the cartridge tank 2. Therefore, even if the cartridge tank 2 is lowered into the tank storage chamber 7, the fuel filler lid 3 does not get in the way, and the cartridge tank 2 can be stored in the tank storage chamber 7 smoothly (see FIG. 2).

The heating device of the present invention is not limited to the above embodiment.
The filler lid 3 and the inlet / outlet lid 4 can block the inlet / outlet 11 of the heating body 1 with the two lids 3, 4, and the filler port lid 3 closes the filler port 5 of the cartridge tank 2. Any size can be used. For example, in a state where the cartridge tank 2 is stored in the tank storage chamber 7, the fuel filler lid 3 may block only the fuel filler 5, and the other inlet / outlet 11 may be blocked by the inlet / outlet lid 4. Further, the abutted portion 3 b of the fuel filler lid 3 may have any size or shape that abuts against the abutting portion 13 of the cartridge tank 2 when the cartridge tank 2 is taken in and out of the entrance / exit 11 of the heating main body 1. Furthermore, the oil filler lid 3 may have a structure in which the oil filler port 5 is closed when the cartridge tank 2 is inserted into the oil receiver 8 and opened when the cartridge tank 2 is removed from the oil receiver 8. For example, it is possible that the fuel filler lid 3 opens and closes in a sliding manner. Further, the restricting portion 31 has a structure in which the fuel filler lid 3 does not sink under the contact portion 13 of the cartridge tank 2 and the contacted portion 3b does not hit the side wall surface of the restricting portion 31 or the cartridge tank 2. However, the present invention is not limited to the above form.
