Next, the operation of the refrigerator having the above configuration will be described.
As described above, in the situation where the refrigerator is installed and used, for example, when the humidity of the installed room becomes high, condensation may occur on the back of the storage body, or the storage body has been exposed to water. Occasionally, water adheres, which may cause water to flow down the back of the cabinet body. In particular, in the case where the vacuum heat insulation panel 4a is used for the heat insulation peripheral wall of the storage body 1 as in this embodiment, when the vacuum heat insulation panel 4a is damaged, condensation is formed on the back surface of the storage body 1 due to the cold air in the storage chamber. In that case, water flows down the back of the main body 1.

  In the refrigerator according to this embodiment, the water flowing down is received by the fitting 35 on the back surface of the main body 1 by the groove 35b and the water from the drain port 35f through the water channel 35e. Drop on the extension 37 a of the support 37. The water dropped on the extension 37a of the water receiver 37 then falls on the evaporating dish 38 from the extension 37a of the water receiver 37 through the drain tube 37b. Then, it evaporates on the evaporating tray 38 by receiving indirect heat in the machine room 29 or direct heat from a part of the condenser 34.

  Therefore, the groove part 35b of the coupler 35 functions as a water receiving part that receives and discharges the water flowing down the back of the main body 1, and the evaporating dish 38 is a receiver that receives the water discharged from the water receiving part. The water receiving device 37 functions as a water guiding means for guiding water discharged from the water receiving portion to the receiver, and the water guiding means evaporates water generated by defrosting of the cooling device. It is a water guide member that leads to the plate 38.

  In this way, in this embodiment, the water flowing down the back of the main body 1 can be prevented from dripping onto the floor surface of the room where the refrigerator is installed. Furthermore, the occurrence of corrosion defects can be prevented.

  In the present embodiment, the evaporating dish 38 is a receiver that receives water discharged by the groove 35b (water receiving portion) of the coupler 35, and the refrigeration cooler that is a cooling device as the receiver. 23 and the evaporating dish 38 for evaporating the water generated by defrosting the refrigeration cooler 27 can be used, so that a separate receiver is not required and the refrigerator is installed in a rational configuration. It is possible to prevent the floor surface from being soiled and corroded.

  In addition, even if it is the base plate 31 of the machine chamber 29 which has arrange | positioned machine parts including the compressor 30 of the store | warehouse | chamber main body 1 as a receiver which receives the water received and discharged | emitted by the groove part 35b of this coupling tool 35 Even if it is good in this way, generation | occurrence | production of the malfunction of the stain | pollution | contamination of the floor surface of the room which installed the said refrigerator, and corrosion with the rational structure using the base plate 31 can be prevented.

  In addition, in this embodiment, it has water guide means for guiding the water received and discharged by the groove 35b (water receiving portion) of the coupler 35 to the receptacle, and thereby discharged from the water receiving portion. Water can be reliably guided to the receptacle, and the occurrence of fouling and corrosion problems on the floor surface of the room where the refrigerator is installed can be more reliably prevented.

  Further, in the present embodiment, the water guiding means is a water receiving member 37 that is a water guiding member that guides water generated by defrosting of the cooling device to the evaporating dish 38, thereby utilizing the water receiving member 37. With this rational configuration, it is possible to more reliably prevent the occurrence of fouling and corrosion of the floor surface of the room where the refrigerator is installed.

  Although this embodiment demonstrated to the example the case where the surrounding wall of the store | warehouse | chamber main body 1 was comprised only by the vacuum heat insulation panel 4a over the whole back wall, you may change the structure of the heat insulating material 4 according to a temperature range. That is, both the vacuum heat insulating panel 4a and the foam heat insulating material 4b are used in the rear projection region of the freezing temperature zone of the ice making room 7 and the freezing room 8, and the refrigerating room 5 and the vegetable room having a higher target temperature than the freezing temperature zone. The rear projection area of the refrigeration temperature zone 6 may be constituted by the vacuum heat insulation panel 4a alone. According to this, even when the vacuum heat insulating panel 4a is damaged, the heat insulating effect by the foam heat insulating material 4b can suppress the occurrence of dew condensation as compared with the case where the vacuum heat insulating panel 4a is configured alone.

  Moreover, although this embodiment demonstrated as an example the case where the compressor 30 is arrange | positioned in the machine room 29, space is provided in the upper surface rear part of the warehouse main body 1, and the compressor 30 is arrange | positioned. Also good. In this case, a receiver that receives the water discharged from the water receiver can be installed without being restricted by the dimensions of the compressor 30.

  Further, in the present embodiment, the evaporating dish 38 or the base plate 31 in the machine room 29 is used as a receiver. However, the present invention is not limited thereto, and a receiver that receives condensed water outside the machine room 29 may be provided separately. In this case, by configuring the receptacle so as to be detachable from the main body 1, the user can confirm the water accumulated in the receptacle and can remove the entire receptacle to treat the water, thereby improving the usability. .

  As mentioned above, although embodiment of this invention was described, this embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
