In this cooling and heating unit 30, carbon dioxide is used as the refrigerant, which has non-flammability, safety and non-corrosion properties, and has little influence on the ozone layer.

  The compressor 31 is disposed inside the heating chamber 21 (see FIG. 2). The compressor 31 compresses the refrigerant (carbon dioxide) from the evaporator 36 to a high temperature and high pressure state. The compressor 31 in the present embodiment is a two-stage compressor that performs a compression operation in two steps. More specifically, the compressor 31 includes a first compressor 31a that performs a first compression operation and a second compressor 31b that performs a second compression operation, and an intermediate heat exchanger therebetween. 31c is provided. The intermediate heat exchanger 31c condenses the refrigerant compressed by the first compression operation by the first compressor 31a and returns the refrigerant to the second compressor 31b.

  The condenser 32 is disposed inside the heating chamber 21 similarly to the compressor 31 (see FIG. 2). The condenser 32 condenses the refrigerant compressed in a high temperature and high pressure state by the compressor 31 to liquefy the refrigerant. As the refrigerant condenses, the air passing around the condenser 32 is heated and heated. When carbon dioxide is used as the refrigerant, the refrigerant becomes supercritical when the temperature exceeds 31 ° C. In such a case, the condenser 32 functions as a so-called gas cooler.

  The cooling and heating unit 30 is provided with an internal heat exchanger 37 and an electromagnetic valve 38 in addition to the above configuration. The internal heat exchanger 37 exchanges heat between the refrigerant (high-pressure refrigerant) from the condenser 32 and the refrigerant (low-pressure refrigerant) from the evaporator 36. More specifically, inside the internal heat exchanger 37, a high-pressure refrigerant pipe 37a through which the refrigerant condensed by the condenser 32 passes, and a low-pressure refrigerant pipe through which the refrigerant evaporated by the evaporator 36 passes. The passage 37b is arranged in such a manner as to have a non-contact countercurrent with a distance allowing heat exchange with each other. The electromagnetic valve 38 is disposed inside the cooling chamber 22 together with the evaporator 36, and permits and regulates the supply of refrigerant to the evaporator 36 by opening and closing.

  In such a cooling and heating unit 30, when the refrigerant circulates, the condenser 32 functions as a heating unit that heats the air passing through the surroundings, and the evaporator 36 functions as a cooling unit that cools the air passing through the surroundings.

  Next, the configuration of the outer door 2 will be described. The outer door 2 has a left side edge (one side edge) supported by a front left side edge of the main body cabinet 1 and a right side edge (other side edge) as a free end. Open and close.

Here, in the present embodiment, a filter material having a mesh-like mesh structure is used, but the present invention is not limited to a mesh-like filter material. In the outer door 2, a guide hole 42 having a fine pore shape whose longitudinal direction is the left-right direction is provided above the outside air inlet 40.

  In the vending machine described above, a cleaning unit 50 is provided in addition to the above configuration. The cleaning unit 50 is for removing dust, dust, and the like attached to the filter member 41 provided so as to cover the outside air introduction port 40, and includes a cleaning brush member 51 and a link mechanism 52.

  As shown in FIG. 6, the cleaning brush member 51 is arranged such that the tip of the brush portion 511 is in sliding contact with the surface of the filter member 41 from the front side of the outside air introduction port 40. More specifically, the cleaning brush member 51 is configured such that the tip of the brush portion 511 planted in the brush body 512 extending in the vertical direction is in sliding contact with the surface of the filter member 41 from the front side of the outside air inlet 40. Arranged. The cleaning brush member 51 is supported by the link mechanism 52 as follows. In the present embodiment, the cleaning brush member 51 is disposed so as to be in sliding contact with the filter member 41 from the front side of the outside air introduction port 40. However, in the present invention, both sides of the outside air introduction port 40, that is, You may arrange | position in the aspect which slidably contacts the surface of the filter member 41 from the front surface side and the rear surface side of the external air introduction port 40, respectively.

  The brush body 512 constituting the cleaning brush member 51 is integrally connected to a front end portion of a horizontally extending support piece 513 provided in a manner penetrating the guide hole 42. The rear end portion of the horizontal extending support piece 513 is connected to a hanging support piece 514 extending in the vertical direction, and the extending end portion of the hanging extending support piece, that is, the lower end portion thereof is shown in FIG. Are connected to a link support piece 515 extending in the front-rear direction. The link support piece 515 is supported by a link mechanism 52 described later, whereby the cleaning brush member 51 is supported by the link mechanism 52.

  As shown in FIG. 7, the link mechanism 52 includes a long plate-like member 521. The long plate-like member 521 is disposed in such a manner that the base end portion can be rotated around the axis of the support pin 522 in the substantially central region of the front end side of the base 1 a of the main body cabinet 1 via the support pin 522. It is. More specifically, the distal end portion of the long plate member 521 rotates around the axis of the support pin 522 as a free end. The link support piece 515 is connected to the distal end portion of the long plate member 521 through a connection pin 523.

  In such a link mechanism 52, when the outer door 2 is in a fully closed state (see FIG. 5), the cleaning brush member 51 is located on the right side of the right side edge side (the other side edge side) of the outside air inlet 40. When the outer door 2 is opened and moved to the fully open state (refer to FIG. 7 and in the broken line state of FIG. 8), the cleaning brush member 51 is located on the left edge side of the outside air inlet 40. It is adjusted so as to be positioned at (one side edge side). As a result, as shown in FIG. 8, when the outer door 2 moves open, the cleaning brush member 51 slides toward the left edge, and when the outer door 2 moves closed, the cleaning is performed. The brush member 51 slides toward the right edge side. The reason why the initial position of the cleaning brush member 51 is on the right side of the outside air inlet 40 is to prevent mischief.

  Further, when the outer door 2 moves from the fully closed state, the link mechanism 52 positions the cleaning brush member 51 at the initial position until the distance of the opening movement reaches a predetermined size. It has been adjusted to. That is, as shown in FIG. 8, the outer door 2 is moved from the fully closed state (the state indicated by the solid line) and is positioned in front of the main body cabinet 1, that is, the main body cabinet 1 below the outer door 2. The cleaning brush member 51 is adjusted to be positioned in the vicinity of the initial position until the base 1a does not exist (the state indicated by the two-dot chain line). The initial position of the cleaning brush member 51 may be adjusted to the outside (right side) of the end of the filter member 41.

  In the vending machine having the above configuration, the product stored in the product storage 5 can be cooled or heated as follows.

It reaches the suction chamber 11 through 12b. The internal air that has reached the suction chamber 11 enters the warm air suction duct 25 from the open warm air suction port 16, passes through the warm air suction duct 25, and then reaches the heating chamber 21. The internal air that has reached the heating chamber 21 is heated when passing around the compressor 31 and the condenser 32, then enters the warm air discharge duct 26, passes through the warm air discharge duct 26, and then passes through the warm air discharge port 17. It reaches the discharge chamber 10 and then passes through the inside of the left product storage 5a and the central product storage 5b. By repeating this, the internal air of the left product storage 5a and the central product storage 5b is heated, and the products stored are heated to a desired temperature state.

  On the other hand, by driving the cool air blower fan 34, the internal air of the right product storage 5c reaches the rear duct 12 from the suction port 12a, and the internal air that has passed through the rear duct 12 passes through the discharge port 12b to the suction chamber 11. To. The internal air that has reached the suction chamber 11 enters the cool air suction duct 23 from the open cool air suction port 14, passes through the cool air suction duct 23, and then reaches the cooling chamber 22. The internal air that has reached the cooling chamber 22 is cooled when passing around the evaporator 36, and then enters the cold air discharge duct 24, and after passing through the cold air discharge duct 24, enters the discharge chamber 10 through the cold air discharge port 15.
