The lower end of the heat shield plate 50 attached to the bottom plate 5 of the outer box 31
The back of the heating chamber 34 is supported by the heat shield plate 50, and one side of the partition plate 58, which is disposed approximately perpendicular to the heat shield plate 50, is fixed to the heat shield plate 50.3. The other side is the rear plate 40 of the outer box 31. The lower end is the bottom plate 5 of the outer box 31
3, and the heat shield plate 50 and the outer box 51 are fixed to the rear plate 4.
The partition plate 58, which forms a substantially H-shape with the partition plate 58, is designed to reinforce the longitudinal strength of the heat shield plate 50, so that when the door 32 is opened or closed, an impact force in the longitudinal direction is applied to the heating chamber 34. Also, there is no risk that the heating chamber 34 and the outer box 31 will be deformed. Therefore, it is possible to reduce the possibility that the lock switch or the like will malfunction when the door is opened or closed. Since the partition plate 58 is disposed at an intermediate portion inside the storage chamber 41, the force acting on the heating chamber 34 in the front-rear direction is applied approximately evenly in the left and right directions. Therefore, even if a force is applied to the heating chamber 34 in the longitudinal direction or thermal expansion occurs, there is no risk that the heating chamber 34 will be deformed unevenly in the left-right direction as in the conventional case. Leakage of high frequency waves within the chamber 34 can be prevented. Furthermore, since the mechanical strength at the rear of the heating chamber 34 is high, the bottom plate 53 of the outer box 31 can be made difficult to deform due to vibrations during transportation or dropping, and damage to the high voltage transformer 45 can be prevented. I can do it.

The air is sucked in and rises along the high voltage transformer 45. Therefore, the high-pressure transformer 45 is cooled by the cooling air sucked from each suction lower 0 . And the cooling air is a high voltage transformer 4
After cooling the magnetron 5, the magnetron 42 is cooled by being blown from the ventilation port 59 to the magnetron 42, and a part of the cooling air that has cooled the magnetron 42 is guided into the heating chamber 34 through the duct 7.
The residue is discharged to the outside from the exhaust lower 2 of the rear plate 40. In this case, the inside of the storage chamber 41 is separated by the first partition plate 58. It is partitioned into both second storage sections 56 and 57, and the cooling air is reliably prevented from flowing backward from the first storage section 56 side to the second storage section 57 side. Since the second housing section 57 can be smoothly ventilated, and the heat radiated from the heating chamber 34 is shielded by the heat shield plate 50, the cooling efficiency of the high voltage transformer 45 can be significantly improved. can be increased. Furthermore, since most of the cooling air taken out from the ventilation port 59 is blown to the magnetron 42, the magnetron 42 can be effectively cooled. In addition, since the side plate 63 of the outer box 31 is not provided with ventilation holes as in the conventional case, the device can sometimes be installed with the side of the device attached to a wall, etc., making installation easier than in the past. Space can be reduced.

One 1411 part of the reinforcing member arranged approximately perpendicular to the support is attached to the support, the other side is attached to the rear plate of the outer box, and the lower end is attached to the bottom plate of the outer box. Since the strength in this direction is reinforced, it is possible to prevent deformation of the heating chamber and the outer box even if force is applied to the heating chamber in the front and back directions, and prevent leakage of high frequency waves from the heating chamber. Malfunctions and damage to electrical parts can be prevented, and safety can be significantly improved.
