FIG. 6 is a view showing a step difference measuring device for measuring a step difference in a front-rear direction between a plurality of doors in the refrigerator shown in FIG. 1 . 7 is a view illustrating the step difference measuring device of FIG. 6 as viewed from the top of the refrigerator. FIG. 8 is a diagram illustrating a step calculation method in the step difference measuring apparatus of FIG. 6 .

6 to 8 , the step difference measuring apparatus 100 may measure the step difference in the front-rear direction between the first door 21 and the second door 22 according to the installation of the refrigerator. However, the present invention is not limited thereto, and it is also possible to measure the step difference in the front-rear direction between the third door 23 and the fourth door 24 . For convenience of description, the first door 21 and the second door 22 will be described as a reference.

A step difference measuring method will be described with reference to FIGS. 7 and 8 . It can be seen from the drawing that the first door 21 protrudes more forward than the second door 22 . In this case, the step difference measuring device 100 may be inserted between the first door 21 and the second door 22 . That is, the insertion part 120 may be inserted between the first door 21 and the second door 22 . Accordingly, the buffer member 160 may contact the inner surface 21c of the first door and the inner surface 22c of the second door.

Insert the insertion part 120 between the first door 21 and the second door 22, and press the step difference measuring device 100 toward the door so that the contact part 130 comes into contact with at least one of the plurality of doors. can Although the drawing shows that the contact portion 130 is somewhat spaced apart from the door due to the third auxiliary buffer member 173, the third auxiliary buffer member 173 is not an essential component for measuring the step difference between the doors and the third auxiliary buffer member 173 Even if the member 173 is present, when the contact portion 130 is pressed, the contact portion 130 may contact the door.

In the drawing, the first contact wall 131 may contact the front surface 21b of the first door, and the second contact wall 132 may be spaced apart from the front surface 22b of the second door. That is, since the first contact wall 131 of the contact part 130 contacts at least one of the plurality of doors, it is possible to stably measure the step by using this as a reference point for measuring the step. At this time, the second step member 150 may be pressed to come into contact with the front surface 22b of the second door. Accordingly, the first step member 140 does not move toward the first door 21 , but the second step member 150 may move toward the second door 22 . Accordingly, as shown in FIG. 8 , the number of the plurality of visible surfaces protruding from the outer surface 130a of the contact part 130 may be different. That is, since the second step member 150 can move in the fourth direction D toward the second door 22 while the first contact wall 131 is in contact with the first door 21 , the step member 140 is , 150), it may be possible to measure the step difference between the doors according to the step difference.

The interval between the scales shown in the contact portion 130 may represent a major scale of 1mm and a minor scale of 0.5mm. However, the size of the scale is not limited thereto.

In FIG. 8 , the first step member 140 is the first surface 141 on the same plane as the outer surface 130a of the contact portion 130 , and the scale of the contact portion 130 outer surface 130a is 0 mm am. The second step member 150 has a fourth surface 154 on the same plane as the outer surface 130a of the contact portion 130, and the scale of the outer surface 130a of the contact portion 130 is 3 mm. Accordingly, since the first step member 140 protrudes 3 mm more than the second step member 150 , it can be seen that the first door 21 protrudes 3 mm more than the second door 22 .

Alternatively, since the step difference between the plurality of surfaces of the step members 140 and 150 is 1 mm, the step difference between the first door 21 and the second door 22 may be calculated. In FIG. 8 , in the first step member 140 , the 2-5 surfaces 142 , 143 , 144 , 145 protrude more in the third direction C than the outer surface 130a of the contact part 130 , but the second step It can be seen that only the fifth surface 155 of the member 150 protrudes more in the third direction C than the outer surface 130a of the contact part 130 . That is, four steps of the first step member 140 may protrude, and one step of the second step member 150 may protrude. Considering this, since the step difference of the plurality of surfaces is 1 mm, when the step difference between the first door 21 and the second door 22 is calculated according to the number of steps between the plurality of surfaces, there is a step of 3 (4-1) mm. can be known

However, the present invention is not limited thereto, and it is also possible to measure the vertical step difference between the third door 23 and the fourth door 24 . For convenience of description, the first door 21 and the second door 22 will be described as a reference, and the rear surfaces 21d and 22d are viewed from the direction.

The base 110 may include a rounding part 110a.

A step difference measuring method will be described with reference to FIG. 10 . It can be seen from the drawing that the first door 21 protrudes more upward than the second door 22 . In this case, the step difference measuring device 100 , 100 may be inserted between the first door 21 and the second door 22 . That is, the insertion part 120 may be inserted between the first door 21 and the second door 22 . Accordingly, the buffer member 160 may contact the inner surface 21c of the first door and the inner surface 22c of the second door.

Insert the insertion part 120 between the first door 21 and the second door 22, and press the step difference measuring device 100 toward the door so that the contact part 130 comes into contact with at least one of the plurality of doors. can

In the drawing, the first contact wall 131 may contact the upper surface 21a of the first door, and the second contact wall 132 may be spaced apart from the upper surface 22a of the second door. At this time, the second step member 150 may be pressed to come into contact with the upper surface 22a of the second door. Accordingly, the first step member 140 does not move toward the first door 21 , but the second step member 150 may move toward the second door 22 . Accordingly, as shown in FIG. 10 , the number of the plurality of visible surfaces protruding from the outer surface 130a of the contact part 130 may be different.

Since the plurality of surfaces and the number of steps protruding from the first step member 140 and the second step member 150 are different, it is possible to measure the step difference in the vertical direction between the doors as in the front-rear step measurement between the doors.

In the above, specific embodiments have been shown and described. However, it is not limited only to the above-described embodiments, and those of ordinary skill in the art to which the invention pertains can make various changes without departing from the spirit of the invention described in the claims below. .
