Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator, and more particularly, to a refrigerator in which a showcase for storing an object to be stored such as food is arranged on the top surface of a top plate of a refrigerator body.
[0002]
[Prior art]
In a restaurant kitchen or the like, a table-type horizontal refrigerator having a top plate disposed at the top is generally used. The main body of this horizontal refrigerator consists of an outer box and an inner box disposed with a required space inside the outer box, and is filled with a heat insulating material in the space between both boxes as a heat insulating box. A heat insulating door that is configured to open and close when an object to be stored is taken in and out is rotatably disposed in an opening portion that is configured on the front surface side. In addition, a machine room containing a refrigeration mechanism including a compressor and a condenser is defined inside the refrigerator body, and when the refrigeration mechanism is activated when power is turned on, cold air is defined in the inner box. It is designed to circulate through the refrigerator compartment. Some horizontal refrigerators configured in this way have a so-called showcase disposed on the top surface of the top plate. Like the refrigerator body, the showcase itself is composed of an outer box, an inner box provided with a required space inside the outer box, and a heat insulating material filled between the two boxes. In addition, a glass door that opens and closes the opening is provided at least at the opening for opening and closing the object to be stored on the upper surface of the opening so as to be slidable along the longitudinal direction of the showcase.
[0003]
The showcase has a plurality of openings that communicate with the internal space of the case at required positions on the bottom surface thereof, and the top plate of the refrigerator body has a position corresponding to each opening of the showcase. Each of the showcases is positioned and installed on the top plate in a state where the opening is aligned with the opening of the refrigerator main body. In other words, a part of the cool air circulating in the refrigerator compartment is introduced into the showcase so that the inside of the case is cooled.
[0004]
[Problems to be solved by the invention]
The showcase is connected by supporting and fixing both openings with a fastening member or the like in a state where the opening provided on the bottom surface thereof is aligned with the opening provided on the top plate of the refrigerator main body. In addition, silicon caulking is applied to the seam position between the outer peripheral edge of the lower end of the showcase and the top plate, and the water used when cooking or other work is performed on the top plate of the refrigerator body, Intrusion into a slight gap is prevented. However, since the connection between the showcase and the refrigerator body is simply a structure that supports and fixes the openings to each other as described above, the connection strength between the two is not sufficiently secured, and the refrigerator is moved. When the refrigerator main body vibrates in the case of, for example, an earthquake or the like, the showcase easily shifts from the main body. As a result, the silicon caulking is broken, and water used for cooking work etc. enters the slight gap between the case and the top plate from the broken portion and stays at the bottom surface, causing corrosion. There is a risk that it will end. In addition, various germs propagate along with this corrosion phenomenon, which causes a problem in terms of hygiene.
[0005]
