周辺他部品への延焼のない不燃構造となっている。In the machine room 11 located at the lower part of the refrigerator body 10, the bottom surface consists of a base plate 12, and a compressor 15 is elastically supported by a vibration isolating rubber 14 attached to a pin 13 protruding from the base plate 12. There is. Reference numeral 19 denotes a control box incorporating a control device (defrost timer) 20 for controlling the defrosting of the evaporator of the refrigeration cycle in the refrigerator, and the control box 19 has a metal shell (cover) 25 and a flexible plastic lock. A metal outer bottom plate 28 is attached to the bottom of the locking tool 23, so that the control device 2
0 is surrounded by a metal plate, and the control box 19
Even in the unlikely event of smoke or ignition from the internal control device 20, it has a non-combustible structure that will not spread the fire to other surrounding parts.

受ける微振動を緩ける緩衝材の役目も果す。As shown in FIG. 1, the dimension W1 between the locking claws 24a and 24b provided on the locking tool 23 facing the control device 20 is made smaller than the width W2 of the control device 20. , W2-W1, the locking claws 24a, 24b are pushed toward the side wall 31 side of the metal shell 25 due to the flexibility of the material of the locking tool 23. At this time, the locking claws 24a, 2
The control device 20 is sandwiched by the restoring force F of the control device 4b, and is firmly held together with the holding portion 32 provided at the rear of the control device 20. Moreover, the locking claws 24a, 24b
Since the outer side of the metal shell 250 is sandwiched between the side walls 31 of the metal outer shell 250, the locking pawl 24 is prevented by the creep phenomenon peculiar to plastics.
This prevents the restoring force F of a and 24b from decreasing. moreover,
Since the locking claws 24a and 24b are interposed between the control bag [δ20 and the side wall 31 of the metal outer shell 25, the control device 2
0 and the metal outer shell 25, there is no direct contact between the control device (defrost timer) 20 and the metal outer shell 25, so there is not only an electrical insulation effect, but also a control device due to magnetic leakage due to proximity or contact between the pivot motor core portion 30 of the control device (defrost timer) 20 and the metal outer shell 25. It also prevents malfunctions,
It also serves as a buffer material that absorbs the contact noise and vibrations of the control device 20 and loosens the slight vibrations received from the compressor 15.

により、前述した緩衝材の役目も合せ持っている。Locking bosses 26a and 26b protruding from the locking tool 23 in a direction parallel to the surface of the base plate 16 are connected to the holes 27a of the control device 20,
27b, and the locking bosses 26a, 26b are pressed and held by the metal shell 25, thereby preventing the control device 200 from falling off or coming off within the control box 19 without fixing with screws. Further, the locking bosses 26a and 26b are
Since the metal outer shell 25 is interposed between the control device 20, it also serves as the aforementioned cushioning material.
