Description

  The present invention relates to a storage form of a refrigerator configured to be stored in a lower space of a section of a system kitchen and a configuration thereof.

  Conventionally, as a device stored in a system kitchen or the like, an electric range oven / table, a gas oven / table, a dishwasher, a garbage disposal machine, etc. are mainly used. In recent years, in particular, even in a dishwasher, a box-type storage unit is a drawer type, and the storage unit is also a drawer-type storage unit from the upper level to the lower level.

  However, in the storage section, there is a water supply / drainage pipe for the sink below the sink. For example, the space is narrower than the other drawer storage sections. There is an example in which a cool box is installed in another section of the system kitchen (see Patent Document 1).

FIG. 7 shows a cold storage for a system kitchen described in Patent Document 1. As shown in FIG. As shown in FIG. 7, it is composed of a container-like storage body 3 that is put in and out of an outer case 2 incorporated in the assembly space 1 of the kitchen storage body, a Peltier element 4, a blower fan 5, a heat exchanger 6, and the like. By disposing a cool box in which the container-like storage body is set to a temperature lower than the ambient temperature in a part of the storage part of the system kitchen, it is possible to prevent the quality of the food from being deteriorated and tasteless. Further, by arranging the air introduction path 7 and the exhaust path 8 for the heat exchanger on the left and right sides of the cool box, an intake / exhaust space can be secured even in a state of being accommodated in the storage part of the system kitchen.

On the front surface of the system kitchen built-in refrigerator, a decorative plate 14A forming a design panel door and a decorative plate 14B with a suction port are configured. With such a configuration, the system kitchen built-in refrigerator 13 can be incorporated without impairing the appearance of the system kitchen.

  FIG. 2 is a perspective view when the system kitchen built-in refrigerator of the embodiment is pulled out to the front, and the system kitchen built-in refrigerator 13 is mainly composed of a storage unit 15 and a machine room 16. The storage unit 15 is composed of a storage case 15A. At the four corners of the storage case 15A, there are a plurality of cold air circulation holes 15B for circulating the cool air inside the storage and making the temperature inside the storage case 15A uniform. A partition 15C is attached to form an air passage in the storage case. A heat insulating door 17 is provided on the front surface of the storage unit 15, and a decorative plate 14A is attached to the heat insulating door 17 in order to unify the appearance of the system kitchen. On the front surface of the machine room 16, a decorative plate 14 </ b> B with a suction port is integrally formed with a suction grill 14 </ b> C.

  FIG. 3 is a partial perspective view of the refrigerator built in the system kitchen according to the embodiment. The machine room 16 includes a radiator 19 of the cooling unit 18, a fan motor 20, a power control board 21, an evaporating dish 22, and an exhaust duct 16A. It is configured. The interior 23 of the storage section 15 is configured by a storage cover 25 that separates the cooler 24 and the storage 23 of the cooling unit 18, an internal stirring fan motor 26, and a rail 27 that slides the storage case 15 </ b> A in the front-rear direction. The interior is configured. The rail 27 includes a fixed rail 27A, an intermediate rail 27B (not shown), and a movable rail 27C. In addition, vacuum heat insulating materials 28 </ b> A and 28 </ b> B are installed in the heat insulating wall of the storage unit 15. Thereby, the thickness of the heat insulation wall of an upper and lower surface can be made thin, and the increase in a storage volume can be anticipated.

  FIG. 4 is a cross-sectional view of the cooling unit of the system kitchen built-in refrigerator according to the embodiment, which is output by the Peltier element 29, the heat conductor 30 for exchanging heat between the cooler 24 and the Peltier element 29, and the Peltier element 29. It is composed of a high-temperature side radiator 19 for exhausting heat, a cooler 24, a Peltier element 29, a heat conductor 30, and a case conductor 31 connecting the radiator 19.

  FIG. 5 is a perspective view of the machine room of the system kitchen built-in refrigerator according to the embodiment. A filter 32 for removing dust is installed in front of the radiator 19, and the filter 32 includes the radiator 19 and a fan. It serves to prevent dust and oil from adhering to the motor 20 and the power supply control board 21. A switch 33 is provided behind the filter 32. When the refrigerator is not used, such as when going out for a long time in winter, the switch 33 can be stopped by the switch 33.

  FIG. 6 is a perspective view when the storage unit of the system kitchen built-in refrigerator of the embodiment is pulled out. The heat insulating door 17 has a guide rail 34 that supports the storage case 15A. The guide rail 34 and the moving rail 27C Are fixedly connected.

  Furthermore, the system kitchen built-in refrigerator 13 can be used as a cold storage box, a drying box, or a warm box depending on the temperature setting.

  Next, the operation in the embodiment will be described. In the machine room 16, the air sucked from the decorative plate 14 </ b> B with the suction port passes through the filter 32, dust is removed, the heat emitted from the Peltier element 29 is exchanged with the radiator 19, and is sucked by the fan motor 20. The power supply control board 21 is cooled. The high-temperature air heat exchanged between the radiator 19 and the power supply control board 21 is guided to the lower exhaust duct 16A, passes through the evaporating dish 22, evaporates the drain water from the inside, and is discharged into the kitchen space. On the storage unit 15 side, the cool air discharged from the internal stirring fan motor 26 passes through the back surface of the storage unit 15 and flows into the storage case 15A through the plurality of cool air circulation holes 15B of the storage case 15A. The air is sucked from the suction port, absorbed again by the cooler 24, and blown to the storage case 15A.

  Furthermore, by attaching the partition 15C to the inside of the storage case 15A, it is possible to secure an air passage inside the storage case 15A even when food is packed.

  Moreover, food in the storage case 15A can be organized by making the position of the partition 15C movable in the front-rear direction.

  Moreover, the refrigerator 13 can be used also as a cold storage box, a drying box, or a warm box by setting the temperature.

  Also, if the fan motor 20 and the power supply control board 21 are integrated, the electrical components can be removed from the front surface during maintenance without taking out the refrigerator 13 incorporating the system kitchen.

  As described above, the refrigerator according to the present invention can be effectively used in a limited space, and thus can be applied to built-in equipment such as a system kitchen.
