The foamed polyurethane heat insulating material 5 is filled and foamed between the outer box 3 and the inner box 4 in the state of supporting in this way.

  After filling the polyurethane foam heat insulating material 5, a compressor and a condenser blower constituting the refrigeration cycle are disposed in the machine room at the lower rear side of the main body 2, a condenser is disposed below the bottom surface of the main body 2, and A cooler, which is an evaporator, is formed in a cooling chamber formed by denting the inner front surface of the inner box 4 so as to straddle the back of the lower refrigerator compartment 10 and the left freezer compartment 11 at the bottom in the right vertical direction. Arrange. Further, as will be described later, the top table 7 is fixed on the top surface 2 </ b> A of the main body 2.

  Then, an air path forming body that forms a cool air circulation duct with the inner box 4 is fixed to the inner box 4, and then the lower vertical partition 13 is fixed to the upper vertical partition 8 and the inner box 4. In this way, the space in the inner box 4 is divided into left and right by the upper vertical partition 8 and the lower vertical partition 13 each provided with a heat insulating material, and the left space thus partitioned left and right in this way. Is partitioned vertically by a horizontal partition 9 provided with a heat insulating material, and is roughly divided into three to form a right refrigerator compartment 10, an upper left refrigerator compartment 12, and a lower left refrigerator compartment 11. .

  A door 15 having a lower right upper portion rotatably supported is provided at the front opening of the right refrigerating chamber 10, and left and upper left portions are also provided at the front opening of the left refrigerating chamber 12 and the freezing chamber 11. Door bodies 16 and 17 that are rotatably supported are disposed.

  As described above, the top table 7 fixed on the top surface 2A of the main body 2 is roughly divided into the box-shaped support tool 17 having an open bottom surface placed on the top surface 2A, and the support. A glass plate 18 that is a hard table plate that is supported on the tool 17 and has good heat resistance and is not easily damaged, and the glass plate 18 can be seen from the outside through an opening 19A that is smaller than the glass plate 18. It comprises a table body 19 which is supported on the glass plate 18 with the support 17 and fixed on the top surface 2A, and will be described in detail below.

  The support 17 is composed of an upper surface 17A having a rectangular shape in plan view that is slightly smaller than the top surface 2A of the main body 2, and four side surfaces 17B formed by bending down the peripheral portion except for a part thereof. On each side surface 17B, a plurality of locking portions 17C project outwardly at predetermined intervals.

  The glass plate 18 has an area slightly smaller than that of the support 17, and the peripheral portion of the glass plate 18, that is, at least on the entire side surface, sometimes also on the upper and lower portions of the periphery, is a sealing material for watertight sealing before mounting. Apply some gel-like silicone sealant. This silicone sealant is a room temperature curing type having moisture resistance, and when cured, it plays a role as the sealing material 20.

  The table body 19 has an opening 19A having a slightly smaller area than the glass plate 18 at the center, has a constant width in plan view, and has an outer end that is slightly larger than the top surface 2A of the body 2. 19B, four side surfaces 19C formed by bending downward except for a part of the peripheral portion thereof, and a portion close to the opening portion 19A on the back surface of the frame body portion 19B. The four vertical locking pieces 19D projecting from each other and the horizontal locking piece 19F extending in the horizontal direction inside the front side surface 19C of the four side surfaces 19C. Each vertical locking piece 19D is provided with a locking hole 19E in which each locking portion 17C protruding from each side surface 17B of the support 17 is fitted and locked. It was established with the same interval).

Next, how to attach and fix the top table 7 on the top surface 2A of the main body 2 will be described below. First, the support tool 17, the glass plate 18, and the table main body 19 are assembled. That is, a support 17 is placed on a work table (not shown), and a glass plate 18 having a silicon sealant applied to the peripheral edge thereof is placed on the support 17. Next, the table body 19 is attached to the support tool 17 so that the glass plate 18 disposed inside the vertical locking piece 19D is sandwiched between the table body 19 and the support tool 17 from above.

  That is, by pushing down the table body 19, each locking portion 17 </ b> C projecting from each side surface 17 </ b> B of the support 17 is inserted into each locking hole 19 </ b> E formed in each vertical locking piece 19 </ b> D of the table body 19. Each is fitted and locked from the inside.

  The glass plate 18 is sandwiched between the upper surface 17A of the support 17 and the opening peripheral edge near the opening 19A of the table body 19 in a positioned state by the locking of the locking holes 19E and the locking portions 17C. The support tool 17, the glass plate 18, and the table main body 19 are assembled and integrated, and the top table 7 without backlash is formed.

  At this time, since the gel-like silicon sealant is applied to the peripheral portion of the glass plate 18, when a predetermined time elapses, the glass plate 18 serves as the sealing material 20 and is water-tightly sealed. Even if water spills on the glass 18, it is surely prevented from entering through the gap between the glass plate 18 and the table body 19.

  On the other hand, the fixing piece 21 whose section has a crank shape is fixed on the top surface 2A with screws 22. Since the gap between the fixing portion 21A of the fixing piece 21 and the top surface 2A is slightly larger than the thickness of the horizontal locking piece 19F formed on the side surface 19C of the table main body 19, the table main body 19 is moved from the front to the rear, The horizontal locking piece 19F of the table main body 19 is inserted into the gap between the fixing portion 21A and the top surface 2A, and the top table 2 is covered from above with the top table 7 covered.

  That is, each side surface 19C of the table main body 19 is in a state where the top table 7 covers the top surface 2A from above so as to overlap each upper end portion of the main body 2 from the outside. After that, the mounting hole opened on the rear side surface 19C of the four side surfaces 19C and the mounting hole formed on the upper rear surface of the main body 2 are matched, and screws 22 are inserted into both mounting holes to top the main body 2. The table 7 is fixed.

    As described above, when the top table 7 is fixed to the main body 2 of the refrigerator / freezer 1, even if the glass plate 18 is provided, it is possible to prevent rattling, and the sealing material 20 provides a watertight seal. Even if water spills on the glass plate 18, it is reliably prevented from entering through the gap between the glass plate 18 and the table body 19 and can be wiped off reliably.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description. It encompasses alternatives, modifications or variations.
