  When the cooling air circulation fan 40 is rotated by driving the motor 42, the cold air is sucked into the lower duct 39 from below the front end of the shelf 38 installed on the lower side in the storage chamber 21, and the cold air passes through the cold air inlet 37. And is sucked into the cold air duct 35. The cold air sucked into the cold air duct 35 is cooled by exchanging heat with the heat absorbing portion 32 by passing the heat absorbing portion 32, sucked from the front of the cold air circulation fan 40, and back of the inner box 25 at the rear. It blows out toward the wall 25A. The cold air blown rearward by the cool air circulation fan 40 collides with the front surface of the back wall 25A and is diffused.

  Here, a cold air discharge member 36 having a plurality of cold air discharge ports 36A formed between both side walls of the storage chamber 21 is attached to the cold air blowing side of the cold air circulation fan 40, and therefore the back wall 25A. The cold air diffused on the front surface of the water is smoothly diffused in the left-right direction of the storage chamber 21, and is blown out substantially uniformly into the storage chamber 21 from the respective cold air discharge ports 36A. The cool air blown into the storage chamber 21 circulates in the storage chamber 21, cools the interior of the storage chamber 21, descends, and returns to the lower duct 39.

  In the present embodiment, the motor 42 that drives the cool air circulation fan 40 is provided on the outer rear surface 20A of the heat insulating box 20 so that the exhaust heat generated by the operation of the motor 42 adversely affects the cooling operation in the storage chamber 21. The inconvenience of affecting can be avoided. Further, since the rotating shaft 43 of the motor 42 and the cooling air circulation fan 40 attached thereto are positioned above the heat absorbing portion 32 in the heat insulating box 20, the condensation from the heat absorbing portion 32 is a cooling air circulation fan. The inconvenience of hitting 40 can be avoided, and the occurrence of electric leakage can be prevented.

  When the motor 42 is driven, the exhaust fan 44 is rotated together with the cool air circulation fan 40. Thereby, since the closing plate 47 is provided between the lower end of the back panel 23 and the back surface 20A of the heat insulation box 20, the inside of the exhaust duct 49 partitioned by the duct panel 48 through the opening of the lower end. Outside air is introduced.

  At this time, the opening formed at the lower end of the back panel 23 corresponds to the communication hole 18 that communicates with the gap 14 formed below the bottom plate 7. Outside air that has flowed into the gap 14 through the communication hole 16A of the lower panel 16 provided on the front surface is introduced through the communication hole 18. In addition to this, outside air that has flowed in from the gap 55A between the decorative panel 22A of the heat insulating door 22 and the bottom surface of the housing portion 9 through the gap 55 between the storage 2 and the bottom surface of the housing portion 9 is inside the exhaust duct 49. To be introduced.

  The outside air introduced into the exhaust duct 49 passes through the heat dissipating part 33 disposed in the exhaust duct 49 and is heated by the exhaust heat from the heat dissipating part 33, and then from behind the exhaust fan 44. The air is sucked and blown toward the back surface 20A of the front heat insulation box 20. The cold air blown forward by the exhaust fan 44 collides with the back surface 20A and is diffused.

  The exhaust blown from the exhaust blow side of the exhaust fan 44 flows into the exhaust interference duct 46 formed in the back panel 23, and a part of the exhaust is formed on the upper surface 23 </ b> A of the back panel 23. It passes through the hole 50 and blows out above the back panel 23.

  Here, the exhaust port member 63 that closes the housing upper opening 61 is provided such that the upper surface 63 </ b> B is spaced from the upper surface 23 </ b> A of the rear panel 23 by a predetermined distance, and the front surface 63 </ b> A is positioned above the exhaust hole 50. Is provided. Thereby, the exhaust gas blown out from the exhaust hole 50 of the back panel 23 is blown out toward the exhaust ports 64 and 65 of the exhaust port member 63 and is blown out to the outside through the exhaust ports 64 and 65. Since the exhaust port member 63 is provided behind the vertical plate 60 erected on the rear end 4A of the top plate 4, the exhaust heat from the heat radiating unit 33 as the temperature control device of the storage 2 is transferred to the top plate 4. It can be discharged to the outside from the rear side.

  Therefore, as compared with the conventional case where the exhaust is discharged from the gap formed between the front opening of the storage unit 9 in which the storage 2 is stored and the storage 2, the user feels uncomfortable due to the exhaust. It can not be.

  Even when an object is placed on the top plate 4, the vertical plate 60 is erected at the rear end 4 </ b> A of the top plate 4. It is possible to avoid the disadvantage that the formed exhaust ports 64 and 65 are blocked by the object. Thereby, exhaust heat can be processed smoothly.

  The exhaust ports 64 and 65 are formed so as to open upward and rearward between the upper end of the back plate 6 and the rear end 4A of the top plate 4, so that an object falls to the rear side of the vertical plate 60 by any chance. Even in such a case, the opening can be secured by the exhaust ports 64 and 65 opened upward or rearward.

  As described above, a part of the exhaust blown into the exhaust interference duct 46 from the exhaust blow side of the exhaust fan 44 collides with the upper surface 23A of the rear panel 23 and then descends in the exhaust interference duct 46. Then, the gas flows out into the accommodating portion 9 through the exhaust holes 51 formed in both side surfaces 23B of the back panel 23.

  Exhaust gas that has flowed into the housing portion 9 from the exhaust hole 51 on the side surface 23B of the back panel 23 or a part of the exhaust gas that has flowed into the housing portion 9 that has flowed out from the exhaust hole 50 on the upper surface 23A is connected to the housing portion 9. It flows into the gap 67 between the heat insulation boxes 20 of the storage 2. A gap 67 between the top surface 20C of the heat insulation box 20 of the storage 2 and the top surface of the housing portion 9 (the lower surface 4B of the top plate 4), the side surface 20D of the heat insulation box 20 and the side surface of the housing portion 9 (side plate 5). In the gap 67 between the inner surface 5 </ b> A and the surface 8 </ b> A of the partition plate 8 on the accommodating portion 9 side, air is likely to stay in a narrow space. However, as in the present embodiment, a part of the air (exhaust gas) blown out from the exhaust fan 44 is caused to flow into the gap 67, whereby air is circulated through the gap 67 between the storage 2 and the accommodating portion 9. Therefore, the occurrence of condensation on the outer surface of the storage 2 can be effectively eliminated.

  Further, in this embodiment, the motor 42 for driving the cold air circulation fan 40 and the exhaust fan 44 and the exhaust fan 44 are provided above the heat radiating portion 33, so that the exhaust provided above is provided. The exhaust heat to the ports 64 and 65 can be discharged smoothly. At this time, both the cold-air circulation fan 40 and the exhaust fan 44 can be operated by driving one motor 42, so that the cost can be reduced.

  On the other hand, when a heating operation for heating the inside of the storage chamber 21 of the storage 2 is performed, the energization to the Peltier element 31 is cut off and the motor 42 is stopped. Then, energization control is performed on the electric heaters H of the shelves 38 installed in the storage chamber 21. When the electric heater H generates heat, the articles on the shelf 38 and the inside of the storage chamber 21 can be heated and kept warm. In the present embodiment, the inside of the storage chamber 21 is heated by the electric heater H, but the present invention is not limited to this, and the heat absorption part is heated by reversing the energization to the Peltier element 31. May be used. However, by using the electric heater H as in this embodiment, the interior of the storage chamber 21 can be smoothly heated with a higher capacity than the heating operation by the Peltier element 31.

  Thus, the storage-incorporated furniture 1 according to the present embodiment as described above constitutes the storage portion 9 whose front surface is opened below the top plate 4 and stores the storage 2 in the storage portion 9. By configuring the outer surface of the heat insulating door 22 with the decorative panel 22A with a material and design that harmonizes with the top plate 4 and the like, furniture with built-in storage harmonized with the top plate 4 and the like can be configured.
