Description

  The present invention relates to a heat insulating structure of a vending machine in which a heat insulating plate is arranged on an inner wall surface of a product storage with an open front, and the product storage is divided into left and right by a heat insulating partition plate.

  In a conventional vending machine, a heat insulating back plate disposed on the back of the product storage is composed of a single plate and attached along the back plate of the outer box, and the bottom of the product storage The heat-insulating bottom plate disposed on the top is also composed of a single plate-like body and is attached along the storage bottom plate of the outer box, and the heat-insulating top plate disposed on the ceiling surface of the product storage is also 1 It is composed of a single plate and attached along the storage ceiling plate of the outer box, and the end face of the heat insulating partition plate contacts the inner surface of the heat insulating back plate, heat insulating bottom plate, and heat insulating top plate. Had been attached.

  By the way, since the outer box is composed of a relatively thin metal plate, a phenomenon of warping so that the central portion is convex outward tends to occur particularly on the back plate side having a large area.

  When such a warp occurs in the back plate of the outer box, the heat insulating back plate also warps. Therefore, if a gap is generated between the heat insulating back plate and the end face of the heat insulating partition plate, the heat insulating partition plate causes the product storage to be stored. In the vending machine that is divided into a heating chamber and a cooling chamber on the left and right, the heat transfer from the heating chamber to the cooling chamber increases, and the heating chamber is heated to cool the cooling chamber. Power consumption increases.

  Therefore, the cushion material is attached to the rear end surface of the heat insulating partition plate, and a double-sided adhesive tape is attached to the portion where the cushion material contacts the heat insulating back plate side, and the heat insulating back plate and the rear end surface of the heat insulating partition plate are attached by the cushion material. It has been proposed to reduce the heat transfer from the inside of the heating chamber to the inside of the cooling chamber by filling the gap between them (for example, see Patent Document 1).

JP2011-145985A

  However, in the conventional vending machine described in Patent Document 1, when the warp of the heat insulating back plate is relatively large, the sealing performance by the cushion material is reduced due to a decrease in the compression degree of the cushion material, and from the inside of the heating chamber. There was a problem that heat transfer into the refrigerator increased.

  In addition, when the adhesiveness of the double-sided adhesive tape decreases and the elasticity of the cushioning material also decreases due to secular change, there is a problem that a gap may be generated between the heat insulating back plate and the end face of the heat insulating partition plate. It was.

  The present invention solves the above-mentioned conventional problems, and in a vending machine in which a product storage is partitioned into a heating chamber and a cooling chamber on the left and right by a heat insulating partition plate, the rear surface that insulates the entire rear surface of the product storage. An object of the present invention is to provide a vending machine capable of reducing the heat transfer between the heating chamber and the cooling chamber even when the central portion of the heat insulating plate is warped so as to protrude outward.

In order to achieve the above object, the vending machine of the present invention insulates the inner wall surface of the product storage with the front face open by at least a rear heat insulating plate and a side heat insulating plate, and further adds the product storage by a heat insulating partition plate. A vending machine that is divided into a left and right side of a warm chamber and a cooler, and the left and right end surfaces are elastic to the side heat insulating plate and the heat insulating partition plate on the front surface of the rear heat insulating plate located on the rear surface of the heating chamber. The heating insulator back heat insulating plate elastically sandwiched between the side heat insulating plate and the heat insulating partition plate is overlapped so that the back heat insulating plate is not exposed to the heating cabinet.

  With the above configuration, even if the heat insulation is reduced in the portion between the back heat insulation plate and the heat insulation partition plate, the heating insulation back heat insulation plate is warped so that the center portion of the back heat insulation plate is convex outward. Since the heat conduction between the part with reduced heat insulation between the rear heat insulating plate and the heat insulating partition and the heating chamber is blocked, the heat transfer from the heating chamber to the cooling chamber should be suppressed. Thus, the power consumption of the vending machine can be reduced.

  According to the present invention, even if the heat insulation performance is lowered at the portion between the rear heat insulating plate and the heat insulating partition plate, the heating insulating rear heat insulating plate is warped so that the central portion of the rear heat insulating plate is convex outward. However, since the heat insulation between the part where the heat insulating property between the rear heat insulating plate and the heat insulating partition plate is lowered and the heat transfer to the heating chamber is blocked, the heat transfer from the heating chamber to the cooling chamber is prevented. The power consumption of the vending machine can be reduced.

  With the above configuration, even if the heat insulation is reduced in the portion between the back heat insulation plate and the heat insulation partition plate, the heating insulation back heat insulation plate is warped so that the center portion of the back heat insulation plate is convex outward. Since the heat conduction between the part with reduced heat insulation between the rear heat insulating plate and the heat insulating partition and the heating chamber is blocked, the heat transfer from the heating chamber to the cooling chamber should be suppressed. Thus, the power consumption of the vending machine can be reduced.

  2nd invention WHEREIN: The said heating warehouse back surface heat insulating board in 1st invention has an elastic deformation member in at least any one of the left and right end surfaces, and is a heat insulating material which comprises a heating room back heat insulating plate. Even if a heat insulating material that is relatively excellent in heat insulation but hardly elastically deforms is used, if the left and right end surfaces are made of elastic deformation members, the left and right end surfaces of the heating chamber rear heat insulating plate are side-insulated. Even if the center of the back heat insulation plate is warped so that it protrudes outward by elastically abutting the plate and the heat insulation partition plate, the heating heat insulation back heat insulation plate is held by the side heat insulation plate and the heat insulation partition plate. can do.

  According to a third aspect of the invention, the warming chamber rear heat insulating plate in the first or second invention has an elastic deformation member on a surface facing the rear heat insulating plate, and a central portion of the rear heat insulating plate is on the outside. When it is warped to be convex, it becomes difficult to create a gap between the rear heat insulating plate and the heating chamber rear heat insulating plate, so the heating chamber via the gap between the rear heat insulating plate and the heating chamber rear heat insulating plate It is possible to suppress heat transfer from the inside to the inside of the refrigerator, thereby reducing the power consumption of the vending machine.

The left side surface of the inner wall surface of the upper space (product storage) is covered with one sheet for heat insulation.

  The right side heat insulating plate 5 is disposed along the right side surface of the inner wall surface of the space above the bottom heat insulating plate 2 (product storage) so that the rear end surface is in contact with the rear heat insulating plate 3. The right side surface of the inner wall surface of the upper space (product storage) is covered with one sheet for heat insulation.

  The top surface heat insulating plate 6 is disposed so that the lower surface of the rear end portion is in contact with the upper end surface of the rear heat insulating plate 3 along the ceiling surface of the inner wall surface of the space above the bottom heat insulating plate 2 (product storage). Then, the entire ceiling surface of the inner wall surface of the space (product storage) on the upper side of the bottom heat insulating plate 2 is covered and insulated.

  The heat insulating partition plate 7 is a heat insulating plate that partitions the left chamber 9 serving as a heating chamber and the middle chamber 10 serving as a cooling chamber, and a rear end surface contacting the bottom heat insulating plate 2 and a rear heat insulating plate 3. A cushion material 12 made of polyethylene foam is provided on the upper end surface in contact with the top heat insulating plate 6.

  The heat insulating partition plate 8 is a heat insulating plate that partitions the middle store 10 serving as a refrigerator and the right store 11 serving as a refrigerator, and includes a lower end surface that contacts the bottom heat insulating plate 2 and a rear end surface that contacts the rear heat insulating plate 3. A cushion material 12 made of polyethylene foam is provided on the upper end surface in contact with the top heat insulating plate 6.

  On the back side of each of the left warehouse 9, the middle warehouse 10, and the right warehouse 11, rear ducts 13, 14, and 15 having an air inlet at the upper end and an air outlet at the lower front are provided.

  And the air cooled or heated by the internal heat exchanger (not shown) etc. which comprise a refrigerant cycle in the lower part in an inside of a warehouse is blown out in the inside by the air circulation fan (not shown). After the product in the cabinet is cooled or heated, it is sucked into the air suction port at the upper end of the rear ducts 13, 14, 15 and descends in the rear ducts 13, 14, 15 to return to the rear ducts 13, 14, 15 returns from the air outlet at the front of the lower part to the part where the internal heat exchanger (not shown) at the lower part of the internal part is disposed.

  In the present embodiment, the left and right end surfaces elastically contact the left side heat insulating plate 4 and the heat insulating partition plate 7 on the front surface of the rear heat insulating plate 3 located on the rear surface of the left chamber 9 serving as a heating chamber, and the left side A heating chamber rear heat insulating plate 16 elastically sandwiched between the surface heat insulating plate 4 and the heat insulating partition plate 7 is stacked so that the rear heat insulating plate 3 is not exposed to the left chamber 9. In addition, the heating chamber rear heat insulating plate 16 is disposed between the rear heat insulating plate 3 and the rear duct 13 of the left chamber 9.

  In the present embodiment, a foamed polystyrene plate having a thickness of about 15 mm is used for the heating chamber rear heat insulating plate 16, and the depth dimension of the rear duct 13 of the left chamber 9 is provided with the heating chamber rear heat insulating plate 16. Therefore, the depth dimension of the rear ducts 14 and 15 (about 30 mm) of the middle warehouse 10 and the right warehouse 11 is about 15 mm smaller, the depth dimension of the rear duct 13 becomes smaller, and the air duct resistance of the rear duct 13 is reduced. In consideration of the increase, the internal circulation fan (not shown) of the left warehouse 9 increases the rotational speed (air flow rate) compared to the case where the heating chamber rear heat insulating plate 16 is not provided.

  Although foamed urethane foam and vacuum heat insulating materials were cited as candidates for the material of the heating chamber back heat insulating plate 16, polystyrene foam was adopted. The reason is that the polystyrene foam is superior in elasticity and the production efficiency of the heat insulating plate than other heat insulating materials, and the vacuum heat insulating material is expensive and increases the cost.

  In order to hold the heating chamber rear heat insulating plate 16 firmly between the left side heat insulating plate 4 and the heat insulating partition plate 7, the thickness of the heating chamber rear heat insulating plate 16 is set to the thickness of the heat insulating partition plate 7 during use (installation).

With the above configuration, as shown in FIG. 3, the central portion of the back heat insulating plate 3 is warped so as to protrude outward, and the cushion material 12 is elastically restored at the portion between the back heat insulating plate 3 and the heat insulating partition plate 7. A space that cannot be covered by force is formed, and a space formed between the rear heat insulating plate 3 and the heating chamber rear heat insulating plate 16 communicates with the space of the cooling chamber (the inner chamber 10), whereby the rear heat insulating plate 3 and the heat insulating partition. Even if the heat insulating property is reduced in the portion between the plate 7 and the heating chamber back heat insulating plate 16, the heat insulating property between the back heat insulating plate 3 and the heat insulating partition plate 7 is reduced (the back heat insulating plate 3 and The space between the heat insulating partition plate 7, the back heat insulating plate 3 and the heating chamber rear heat insulating plate 16, which communicates with the space of the cooling chamber (inside chamber 10), and the heating chamber (left chamber 9). Since the passage through which heat is transmitted is blocked, the heat transfer from the heating chamber (left chamber 9) to the cooling chamber (center chamber 10) Obtain it can, thereby reducing the power consumption of the vending machine.

  In the present embodiment, the left and right end faces are elastically in contact with the left side heat insulating plate 4 and the heat insulating partition plate 7 on the front surface of the rear heat insulating plate 3 located on the rear surface of the left chamber 9 serving as a heating chamber, and the left side The heating chamber rear heat insulating plate 16 elastically sandwiched between the surface heat insulating plate 4 and the heat insulating partition plate 7 is stacked so that the rear heat insulating plate 3 is not exposed to the left chamber 9, but as shown in FIG. The left and right end surfaces are in elastic contact with the heat insulating partition plate 7 and the heat insulating partition plate 8 on the front surface of the rear heat insulating plate 3 located on the back surface of the central store 10 serving as a cooling box, so that the heat insulating partition plate 7 and the heat insulating partition plate 8 are in contact with each other. The inner cooling chamber rear heat insulating plate 17 that is elastically sandwiched between the rear cooling heat insulating plates 17 is stacked so that the rear heat insulating plate 3 is not exposed to the inner storage 10, and the inner cooling chamber rear heat insulating plate 17, the rear heat insulating plate 3, and the depth dimension are set. Arranged between the rear duct 14 of the central warehouse 10 which is made smaller like the depth dimension of the rear duct 13 of the left warehouse 9. And it may be.

  However, if only one of the heating chamber rear heat insulating plate 16 and the middle cooling chamber rear heat insulating plate 17 is provided, it is more effective to provide the heating chamber rear heat insulating plate 16 than to provide the middle cooling chamber rear heat insulating plate 17. It is.

  The left warehouse 9 may be switched to a refrigerator by a heat exchanger (not shown) in the lower part of the warehouse in the summer or middle period (spring, autumn), and the left warehouse 9 is heated. When the storage is used, the interior may be heated by at least one of an internal heat exchanger (not shown) at the lower part of the interior and an electric heater (not shown) at the lower part of the interior. Absent.

  Moreover, the inside store | warehouse | chamber 10 may provide an electric heater (not shown) in addition to the in-house heat exchanger (not shown) in the lower part of the inside of the store, and may switch to a heating cabinet in winter.

(Embodiment 2)
FIG. 5 is a schematic cross-sectional view of the main body excluding the door of the vending machine according to the second embodiment of the present invention, cut laterally at the product storage part.

  In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The present embodiment is different from the first embodiment in that the cushioning member 18 is provided as an elastic deformation member on the left end surface of the heating chamber rear heat insulating plate 16, and the other configurations are the same as those of the first embodiment. .

  The material of the cushion material 18 is, for example, urethane foam or independent foamed polyethylene foam, and uses a material that matches the size of the left end face of the warming chamber rear heat insulating plate 16. Paste to the left edge. If the two dimensions are different, a mounting jig is required and workability is lowered. However, if both dimensions are matched, the jig can be mounted at a predetermined position without using the jig and workability is improved.

  As described above, the vending machine according to the present embodiment uses the heating chamber rear heat insulating plate 16 having the elastic deformation member (cushion material 18) on at least one of the left and right end surfaces in the configuration of the first embodiment. Even when a heat insulating material that is relatively excellent in heat insulating properties but hardly elastically deforms is used for the heat insulating material constituting the heating chamber rear heat insulating plate 16, the left side heat insulating plate 4 and the heat insulating partition plate are also used. Even if there is an error (manufacturing size variation) from the design dimension in at least one of the space between the heater 7 and the horizontal dimension (width dimension) of the heating chamber rear heat insulating plate 16, the lateral end face part is elastically deformed. If it comprises a member (cushion material 18), the left and right end surfaces of the heating chamber rear heat insulating plate 16 are elastically brought into contact with the left side heat insulating plate 4 and the heat insulating partition plate 7, so that the center of the rear heat insulating plate 3 is When the part warps so that it protrudes outward There can also hold a warming cabinet rear heat insulator 16 at the left side insulation plate 4 and the heat insulating partition plate 7.

However, in this case, since the cushion material 18 and the cushion material 12 are in contact with each other, the cushion material 18 is provided on the left end surface of the warming chamber back heat insulation plate 16. Since the force for holding the heating chamber rear heat insulating plate 16 with the left side heat insulating plate 4 and the heat insulating partition plate 7 is lower than the case, the cushion material 18 and the cushion material 12 are likely to become a passage for heat (air). ,Caution must be taken.

(Embodiment 3)
FIG. 7 is a schematic cross-sectional view of the main body excluding the door of the vending machine according to the third embodiment of the present invention, which is cut horizontally at the product storage portion.

  In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The present embodiment is different from the first embodiment in that the heating chamber rear heat insulating plate 16 has a cushion material 19 as an elastic deformation member on the surface facing the rear heat insulating plate 3, and other configurations are implemented.

As shown in FIG. 8, when the central portion of the back heat insulating plate 3 is warped so as to protrude outward, a gap is not easily formed between the back heat insulating plate 3 and the heating chamber back heat insulating plate 16. Therefore, even if at least one of the front surface of the back heat insulating plate 3 and the back surface of the heating chamber back heat insulating plate 16 is uneven, there is a gap between the back heat insulating plate 3 and the heating chamber back heat insulating plate 16. Therefore, it is possible to suppress the heat transfer from the heating chamber (left chamber 9) to the cooling chamber (center chamber 10) through the gap between the rear heat insulating plate 3 and the heating chamber rear heat insulating plate 16. Thus, the power consumption of the vending machine can be reduced.
