  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of a vending machine according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view around a cooler according to Embodiment 1 of the present invention.

  1 and 2, a box-shaped vending machine main body 1 having an open front, a product storage chamber 2 provided in a warehouse, a front door 3 for opening and closing the front opening of the main body 1, and a front door 3, an inner door 4 of the product storage chamber 2 that can be opened and closed, a product storage shelf 5 for storing products located inside the product storage chamber 2, An interior duct 6 having an exhaust port 6b on the lower front surface and integrally formed with an air passage extension 6c extended in the front-rear direction of the product storage chamber 2 is installed at the bottom of the bottom of the product storage chamber 2. Yes.

  A heat exchanger 7 is disposed on the bottom surface of the product storage chamber 2 in front of the exhaust port 6 b so as to face the exhaust port 6 b. The fan 8 for blowing the cool air cooled by the heat exchanger 7, the fan duct 9 for fixing the heat exchanger 7 and the internal duct 6, and the product storage chamber 2 generate heat when energized. A blower unit 12 including a heater BOX unit 11 that houses the heater 10 is installed. A claw portion 9a is provided on the upper back surface of the fan duct 9, and an engaging portion 6d is provided on a portion facing the claw portion 9a of the fan duct 9 above the exhaust port 6b of the internal duct 6, respectively. The fan unit 12 and the internal duct 6 can be fitted by inserting the claw part 9a into the joint part 6d, and the heat exchanger 7 is sandwiched between the air unit 12 and the internal duct 6 to fasten screws or the like. The heat exchanger 7 and the internal duct 6 can be installed in the product storage room 2 without using any members.

  At this time, by fitting the sheet metal parts and the like so that the air path of the circulating air in the chamber that continues from the internal duct 6 to the air outlet 12a of the blower unit 12 through the heat exchanger 7 does not leak in the middle. The structure is a sealed structure. At this time, depending on the type of the vending machine having a different depth, adjustment is made by the length of the air passage extension 6c so that the air outlet 12a of the blower unit 12 is located in front of the depth direction in the cabinet. . Moreover, the flange 13a by bending of sheet metal parts is provided on both side surfaces of the internal duct 6, and the flange 13a is also provided on the entire side surface of the air passage extension 6c.

  Further, a flange 13b is provided on the top surface of the internal duct so as to narrow the intake port area of the internal duct.

  The operation and action of the vending machine configured as described above will be described below.

  First, when the product storage chamber 2 is set to be cooled, the circulation air is sucked in from the intake port 6a at the top of the duct 6 by the function of the blower fan 8. The sucked air is cooled by the heat exchanger 7 and cools the products stored in the product storage shelf 5.

  Similarly, when the product storage chamber 2 is set to warm, the sucked air is warmed by the heater 10 to heat the product stored in the product storage shelf 5.

  At this time, since the air path of the circulating air in the warehouse that continues from the internal duct 6 to the air outlet 12a of the blower unit 12 has the air path extension 6c that is a part of the internal duct 6, the air outlet 12a is stored in the product. It can be located further forward in the depth direction of the chamber 2. Thereby, the circulating air in the warehouse is blown out from the front, and since the intake port 6a of the internal duct 6 is on the back surface, the circulation of the air in the product storage chamber 2 is convection over the entire area, Since the target load is reduced, the operating rate of the cooling system can be lowered, and the energy consumption can be reduced. In addition, since the air passage extension 6c is integrated with the internal duct 6, it is possible to reduce time in the exchange work at the time of service and the installation of the internal duct 6 at the time of assembly work.

  Also, the integration leads to a reduction in the number of parts, and the cost can be reduced. Moreover, since the flange 13a is provided in the both sides | surfaces of the internal duct 6 and the side surface perimeter of the air path extension part 6c, the attachment attitude | position of the internal duct 6 is stabilized by strength improvement, and further workability | operativity is improved. I can plan. Further, by providing a flange 13b on the top surface of the internal duct 6 and reducing the area of the air inlet 6a of the internal duct 6, the amount of air convection in the product storage chamber 2 is reduced, thereby further reducing energy consumption. Reduction can be achieved.

  In the present embodiment, the heater 10 is used for heating in the cabinet, but the heat exchanger 7 may be used as a condenser by a heat pump circuit. In this case, COP at the time of heating can be enlarged, and there is an effect that further reduction of energy consumption can be realized.

  As described above, since the vending machine according to the present invention can reduce energy consumption by forming an air passage, the vending machine can also be applied to uses such as a cold storage cabinet.
