[Common to Embodiments 1 to 8]
(Remaining heat recovery device)
14 and 15 are partial schematic diagrams for explaining a residual heat recovery device of the cooling and heating device installed in the vending machine according to Embodiments 1 to 8 of the present invention. FIG. 14 is a front view, and FIG. It is sectional drawing of a side view.
In FIG. 14A, the wall surface residual heat pipe 40 constituting the residual heat recovery device 4 was repeatedly installed in a U-shape with a predetermined curvature, which was installed on the side surface 201 of the vending machine 1000, and a straight line portion. Are arranged horizontally. And the edge part of a linear part faces the front side of the vending machine 1000 in the horizontal direction, and the coupler or coupling 40c for connection with other piping is installed. For example, in the cooling and heating device 110 (see FIG. 3), the pipe 34 is connected by one coupler or joint 40c, and the pipe 45 is connected by the other coupler or joint 40c. Connection work can be executed at the position. Therefore, connection is easy, and manufacture and maintenance become easy.

In FIG. 14B, the wall surface residual heat pipe 40 is repeatedly bent into a U shape with a predetermined curvature, and the straight portion is arranged in the vertical direction. And the edge part of a linear part is orient | assigned to the horizontal direction, and the coupler or coupling 40c for a connection with other piping is installed.

Therefore, the warm heat released from the wall surface residual heat pipe 40 is transmitted to the side surface 201 and released from the outside of the side surface 201 (right side in the figure) to the atmosphere.

  In FIG. 15B, the wall surface residual heat pipe 40 is thermally connected by a tape T in place of the brazing R in FIG. At this time, if the heat conductive tape T is used, the heat released from the wall surface residual heat pipe 40 is not only directly transmitted to the side surface 201 but also transmitted to the side surface 201 via the tape T, and It is released into the atmosphere from the outside (right side in the figure). Since the tape T is attached intermittently, the heat insulating material 300 penetrates between the tape T and the side surface 201. However, if the tape T is attached over substantially the entire length, the heat insulating material 300 is inserted. Does not enter between the tape T and the side surface 201.

[Embodiment 9]
(Cooling and heating device-9)
FIG. 16 schematically illustrates a cooling and heating device installed in a vending machine according to Embodiment 9 of the present invention, (a) is a partial side view, and (b) is a circuit diagram.
In FIG. 16 (a), the cooling and heating device 900 installed in the vending machine 9000 includes the residual heat recovery device 4 (formed by the wall surface residual heat pipe 40) described in the first to eighth embodiments. Is installed in the machine room 700 in place of the installation. And the heat absorption part 51 was connected to the wall surface residual heat piping 40 which forms the residual heat recovery apparatus 4 so that heat transfer was possible, and the thermal radiation part 53 was connected to the side surface 201 (not shown) or the back surface 202 of the housing 20 so that heat transfer was possible. A heat pump 50 (having a heat absorption part 51, a heat insulation part 52, and a heat radiation part 53) is installed.

  Therefore, the residual residual heat (warm heat) of the refrigerant is transmitted to the back surface 202 via the heat pump 50 and used for heat retention of the product storage chamber 401. Therefore, the same energy saving effect as in the first to eighth embodiments can be obtained. At this time, the form of the connection means 60 which connects the wall surface residual heat piping 40 and the heat absorption part 51 so that electroheating is possible is not limited. For example, if it is detachably connected by a band, a clip, or the like, it is quick and easy to switch execution / stop of the residual heat recovery. Moreover, the member in which the hole is formed may be fixed by welding to the wall surface residual heat pipe 40, and the heat absorbing portion 51 may be inserted into the hole.

FIG. 16B shows a thermosiphon (same as a loop heat pipe) as an example of the heat pump 50. The thermosiphon 50 a is formed of an evaporation container 51 a that constitutes the heat absorption part 51, a vapor pipe 52 a and a liquid pipe 54 a that constitute the heat insulation part 52, and a condensation pipe 53 a that constitutes the heat radiation part 53.
A known working fluid is stored in the evaporation container 51a, and the working fluid rises in temperature due to the inflow of warm heat into the evaporation container 51a, and the density decreases or evaporates.
The steam pipe 52a communicates with the upper part of the evaporation container 51a and is disposed substantially vertically at a position closer to the front surface on the side surface 201 of the housing 20. Therefore, the working fluid whose density has been reduced or evaporated rises in the vapor pipe 52a.

The condensing pipe 53a is formed by a plurality of horizontal condensing pipes 53b arranged substantially horizontally toward the rear surface on the side surface 201 of the housing 20, and an arc condensing pipe 53c that connects the horizontal condensing pipes 53b in an arc shape. Yes. Therefore, the working fluid that has risen through the vapor pipe 52a releases warm heat in the condenser pipe 53a (same as the horizontal condenser pipe 53b and the circular arc condenser pipe 53), so that the temperature drops and the density increases or condenses. Then, the condenser pipe 53a is lowered.
The liquid pipe 54a communicates the lower end portion of the condensing pipe 53a and a position close to the bottom of the evaporation container 51a. Therefore, the working fluid descending the condensing pipe 53a returns to the evaporation container 51a via the liquid pipe 54a. At this time, since the liquid pipe 54a communicates with a position close to the bottom of the evaporation container 51a, the working fluid having a reduced density or evaporated in the evaporation container 51a may enter the liquid pipe 54a. Therefore, the circulation direction of the working fluid is not reversed.

The type and quantity of the heat pump 50 and the installation position of the heat radiating part 53 are not limited. Moreover, the wall surface residual heat piping 40 and the heat insulation part 52 may be enclosed by a heat insulating material, and the dissipation of the residual heat to air | atmosphere may be suppressed. The working fluid is appropriately selected according to specific heat, evaporation temperature, latent heat of vaporization, environmental harmony, etc., and is not limited.
In addition, since the residual heat recovery device 4 in the ninth embodiment is installed outside the commodity storage 401, the relocation of the wall surface residual heat pipe 40 in the first to fourth embodiments is referred to as “external residual heat pipe”. (Refer to claim 5), and the relocated wall surface residual heat pipe 40 in the fifth and sixth embodiments may be read as "external heating pipe" (see claim 7).

  According to the present invention, the remaining heat of the refrigerant that has heated the product storage chamber is used for heat retention of the housing, and is highly energy-saving. Therefore, it can be widely used as various vending machines.
