BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a control box attached to an outer box.

0002

[Prior Art] In recent years, electronic control has become mainstream for refrigerators, and therefore it has been proposed to attach a plastic control box to the top of the refrigerator and store the control board and electrical components in this control box. has been done.

A conventional refrigerator will be explained below with reference to FIGS. 6 to 9. Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the boxes 2 and 3. 5 is the door of the freezer compartment 6.

A hole 8 is formed in the top surface 7 of the outer box 2. This hole 8 forms a flange 9 recessed toward the inner box 3 side. Reference numeral 10 denotes a control box made of synthetic resin, and has a flange 10b extending outward at a position slightly lower than the upper end 10a.

[0005]The periphery is fixed with tape 12 so that the flange 9 of the hole 8 and the flange 10b of the control box 10 come into contact with each other from the inside of the outer box 2. At this time, the upper end 10a of the control box 10 slightly protrudes above the flange 9.

Reference numeral 13 denotes a control board, which is connected to the control box 10.
A screw 14 is fixed to the protrusion 10c.

[0007] The control box 10 also has a recess 10.
d is formed, and an electrical component 15 such as a transformer is attached to this recess 10d. This electrical component 15 has frames 16 and 17 extending in opposite directions, one of which is inserted into a notch 18 formed in a step 10e that forms a recess 10d of the control box 10, and the other is inserted into a screw 14 of the control box 10. It's stopped.

[0008] Then, the control box 10 and frame 16 are covered with aluminum foil tape 11 from the inner box 3 side, and the heat insulating material 4 is
I try not to leak it. Further, this aluminum foil tape 11 is heated with a heat radiation pipe (not shown). Further, 19 is a lid that covers the upper surface of the control box 10.

[0009]

[Problems to be Solved by the Invention] However, as is clear from the above structure, there is a problem of leakage unless the foaming pressure of the heat insulating material 4 secures the seal between the hole 8 of the outer box 2 and the control box 10. there were. Further, since the control box 10 is made of synthetic resin, there is a problem in that the control box 10 is easily deformed if the board is thin.

[0010] Also, the electrical component 15 is also attached to one frame 16.
It is difficult to position it because it is simply inserted into the notch 18.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a refrigerator in which the control box can be securely mounted to prevent leakage of the heat insulating material.

0012

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention consists of a hole formed in an outer box, and a control box made of synthetic resin that closes the hole and houses electrical components. The control box has a projection extending upward, and a flange is formed around a hole in the outer box to provide a hole into which the projection is inserted.

Further, a recess is formed in the control box, a notch is provided in the step of the recess, and a hole is provided in the frame of the electrical component in the recess so that the notch contacts the upper surface of the step of the control box. A cross-shaped projection is provided that projects downward from the upper surface of the stepped portion of the control box and engages with a hole in the frame, and the frame on the opposite side of the frame of the electrical component is attached to the control box with screws.

[0014]

[Function] With the above configuration, positioning between the control box and the hole in the outer box can be easily performed, and the positioning and fixing of the electrical components can be easily done by engaging one side with the cross-shaped protrusion and then screwing the other side. It's easy.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. Structures that are the same as those of the prior art will be denoted by the same reference numerals, and detailed explanation thereof will be omitted.

The flange 10b of the control box 10 has upwardly projecting protrusions 21 formed on each of its four sides. Further, holes 22 are formed in the flange 9 of the outer box 2 at positions facing the projections 21, respectively.

Further, a cross-shaped projection 23 extending downward is formed on the upper surface side of the stepped portion 10e of the control box 10. This protrusion 23 is inclined so that it becomes thinner as it approaches the tip. Further, a hole 24 that engages with the projection 23 is formed in the frame 16 of the electrical component 15.

Therefore, the control box 10 and the outer box 2 are attached by engaging the protrusion 21 and the hole 22, and then attaching the flanges 9 and 10.
Since the degree of adhesion is increased by bringing the bs into contact with each other, positioning can be easily performed even if the wall thickness of the control box 10 is thin, and therefore the work of applying the tape 12 can be easily performed.
Improves work efficiency.

Furthermore, one frame 16 of the electrical component 15
After inserting the frame 16 through the notch 18, the hole 24 of the frame 16 is inserted into the cross-shaped protrusion 23, and the other frame 17 is screwed, so that the hole 24 is inserted into the protrusion 23 and positioning can be ensured. Therefore, since the aluminum foil tape 11 can be reliably attached, there will be no leakage of the heat insulating material.

[0020]

As is clear from the above embodiments, in the present invention, the flange of the control box and the flange of the recess are engaged with each other through the projection and the hole, so that positioning can be ensured. Also,
The frame of the electrical component and the cross-shaped protrusion formed on the top surface of the notch of the control box are engaged and the other frame is screwed, so the engagement between the protrusion and the hole is ensured, making positioning easy. . Therefore, the heat insulating material will not leak out due to the foaming pressure.
