  Hereinafter, the refrigerator 10 which concerns on embodiment of this invention is demonstrated in detail based on drawing. In the following description, parts having the same configuration are denoted by the same reference numerals, and repeated description is omitted. Further, in the following description, the directions of up, down, front, back, left, and right are used as appropriate, but left and right indicate the case where the refrigerator 10 is viewed from the front.

  With reference to FIG. 1, schematic structure of the refrigerator 10 of this form is demonstrated. 1A is a perspective view of the refrigerator 10 viewed from the front, and FIG. 1B is a perspective view of the refrigerator 10 viewed from the rear.

  With reference to FIG. 1 (A), the refrigerator 10 is a comparatively small thing whose capacity | capacitance is about 100 liters, for example, arrange | positions it in a living room or a bedroom, and is used auxiliary. The refrigerator 10 has a heat insulation box 11, and a wine chamber 20 and a refrigerator compartment 21 are formed in the heat insulation box 11 from the top. The wine chamber 20 has a volume capable of storing a plurality of wines in a state where the wine to be stored is brought down, stores wine or food other than wine, and is cooled to 0 ° C. or higher and 20 ° C. or lower. The refrigerator compartment 21 stores beverages such as beer other than wine, foods, and the like, and is cooled to, for example, 0 ° C. or more and 10 ° C. or less.

  The front opening of the wine chamber 20 is closed by a heat-insulating drawer-type heat insulating door 12, and by pulling the heat-insulating door 12 forward, it is possible to take out the wine in a fallen state.

  The front opening of the refrigerator compartment 21 is closed with a drawer-type heat insulating door 13, and food and the like can be taken in and out from the front opening of the refrigerator compartment 21 by pulling out and opening the heat insulating door 13.

  In this embodiment, the upper surface of the refrigerator 10 is constituted by a transparent plate 14 made of a transparent member. As will be described later, the transparent plate 14 is made of glass or synthetic resin that closes an opening formed on the upper surface of the heat insulating box 11 from above and transmits visible light. Further, the heat insulating foam, which is a light shielding material, is not filled between the transparent plate material 14 and the wine chamber 20. Therefore, the wine stored in the wine chamber 20 through the transparent plate member 14 can be viewed from above.

  The transparent plate 14 is formed of a rectangular transparent region 15 formed in the central portion and a frame-shaped non-transparent region 16 formed in the peripheral portion. The transparent region 15 is disposed above an opening of the heat insulating box 11 described later and transmits visible light. The wine stored in the wine chamber 20 can be visually recognized through the transparent region 15. The non-transparent region 16 is rendered non-transparent by painting the lower surface thereof. By doing so, the other member formed under the non-transparent region 16 can be hidden, and the design appearance can be improved.

  In addition, as shown to FIG. 1 (B), the some opening part 18 is formed by opening the cover of the rear surface side of the refrigerator 10. As shown in FIG. From the opening 18, air heated by a condenser or the like of the refrigeration cycle is released to the outside.

  With reference to the side sectional view of FIG. 2, the structure of the refrigerator 10 of this embodiment will be further described. The heat insulation box 11 which is the main body of the refrigerator 10 includes an outer box 24 made of a plate material such as a steel plate, an inner box 23 made of a synthetic resin plate disposed inside the outer box 24, and an outer box 24 and an inner box 23. And a heat insulating material 25 made of hard urethane or the like filled in a gap formed therebetween.

  An opening is formed on the upper surface of the inner box 23, and an opening is also formed on the upper surface of the outer box 24. These openings are closed from above by a transparent plate 14 or the like. A configuration in which the transparent plate member 14 and the like close the opening will be described later.

  As described above, the storage room formed as the internal space of the inner box 23 is divided into an upper wine room 20 and a lower refrigerator room 21, and the wine room 20 and the refrigerator room 21 are insulated by a heat insulating partition 38. It is partitioned. A storage container 50 that can be pulled out together with the heat insulating door 12 is disposed in the wine chamber 20, and the wine 54 is placed in a fixed container 53 disposed inside the storage container 50. Further, the storage container 50 and the fixed container 53 are made of a transparent synthetic resin that allows light irradiated from below to pass upward.

  The LED 29 and the light guide plate 26 are disposed below the storage container 50, and the LED 29 and the light guide plate 26 are covered with a protective cover from above. With such a configuration, the light emitted from the LED 29 can be diffused toward the surroundings, and the light can be uniformly irradiated upward. By illuminating the wine 54 from below, the user can visually recognize the brand of the wine 54 stored in the wine chamber 20 through the transparent plate 14 even when the room where the refrigerator 10 is placed is dark. can do. Further, by illuminating the wine 54 from below with the LED 29, it is possible to visually create a high-class feeling.

  In the refrigerator compartment 21, storage containers 51 and 52 that can be pulled out forward are arranged. Since the indoor temperature of the refrigerator compartment 21 is lower than that of the wine compartment 20, the storage containers 51 and 52 can store beverages such as beer and food.

  A blower chamber 41 and a cooling chamber 40 partitioned by partition plates 45 and 46 made of a synthetic resin plate are formed on the back side of each storage chamber described above. The cooling chamber 40 incorporates an evaporator 30 for cooling the cool air blown to each storage chamber. The evaporator 30 forms a vapor compression refrigeration cycle by being connected to the compressor 31, a condenser (not shown), an expansion means (not shown) and a refrigerant pipe. The operation of the vapor compression refrigeration cycle is controlled by a control device (not shown). In the blower chamber 41, the cool air that is cooled in the cooling chamber 40 and blown into each storage chamber once flows and functions as a blower passage.

  A blower 47 for blowing cool air cooled inside the cooling chamber 40 is attached to the partition plate 46 that divides the cooling chamber 40 forward. In addition, air outlets 42 and 44 and a return port 43 are formed in the partition plate 45 that partitions the front of the blower chamber 41. Cold air is blown out from the air outlet 42 toward the wine chamber 20, and cold air is blown out from the air outlet 44 toward the refrigerator compartment 21. The cold air that has cooled the refrigerator compartment 21 returns to the cooling chamber 40 from the return port 43. The cold air that has cooled the wine chamber 20 returns to the cooling chamber 40 via a return port (not shown).

  The operation of the refrigerator 10 having the above configuration is as follows. When the control device operates the compressor 31 based on the output of the temperature sensor that measures the temperature of each storage, the evaporator 30 cools the air inside the cooling chamber 40. The cool air cooled inside the cooling chamber 40 is blown to each storage chamber by a blower 47 that rotates based on an instruction from the control device. Specifically, the cold air blown by the blower 47 is blown into the blower chamber 41 formed in front of the cooling chamber 40 and then blown into the wine chamber 20 via the blowout port 42. The cold air that has cooled the wine chamber 20 returns to the cooling chamber 40 via a return port (not shown). A part of the cold air flowing into the blower chamber 41 is blown from the blower outlet 44 to the refrigerator compartment 21 through the blower outlet 44. The cold air that has cooled the refrigerator compartment 21 returns to the cooling chamber 40 via the return port 43. When the indoor temperature of each storage reaches a predetermined temperature as the cold air circulates through each storage along such a path, the control device stops the operation of the compressor 31 and the blower 47.

  Further, if the cooling of the cool air by the evaporator 30 is continued as described above, frosting proceeds in the evaporator 30 and the efficiency of heat exchange and ventilation is reduced due to the frosting. The defrosting process is performed. Furthermore, you may adjust the ventilation volume of cold air with the damper which is not shown in figure opened and closed by a control apparatus.

  In addition, a touch panel type operation unit 64 that can be operated from the upper surface of the refrigerator 10 is disposed on the front side of the upper surface of the refrigerator 10, and the user operates the operation unit 64 to cause the LED 29 to emit light. The wine 54 stored in can be illuminated. Moreover, the user can adjust the cooling temperature etc. of each store room of the refrigerator 10 by operating the operation part 64.

  Furthermore, a charging unit 60 that can charge a mobile device such as a smartphone in a contactless manner is disposed on the upper rear side of the refrigerator 10. By doing in this way, the portable apparatus which the user who rests on the bed and sofa arrange | positioned in the vicinity of the refrigerator 10 can be set | placed on the top | upper surface of the refrigerator 10, and can be easily charged with the charging unit 60.
