  As shown in FIG. 8, the locking portion 52 has a substantially cylindrical shape whose diameter gradually increases from the rear toward the front. Further, the diameter D1 of the lower through hole 43A is set to be larger than the diameter D2 of the front end of the locking portion 52 (see FIGS. 6 and 8). The diameter D3 of the upper through-hole 43B is set to be smaller than the diameter D2 of the front end in the locking portion 52 and larger than the diameter D6 of the rear end in the locking portion 52. That is, the locking portion 52 of the handle attachment portion 50 can pass through the lower through hole 43A, but cannot pass through the upper through hole 43B. The width D4 (the length in the left-right direction orthogonal to the up-down direction) of the communication hole 43C is set smaller than the diameter D3 of the upper through-hole 43B and larger than the diameter D5 of the protrusion 51. . The rear end of the locking portion 52 and the protruding portion 51 can pass through the communication hole 43C in the vertical direction.

  With the above configuration, when attaching the warming chamber side handle member 40 to the handle mounting portion 50, the locking portion 52 is inserted into the lower through hole 43A, and then the warming chamber side handle member 40 is lowered. By allowing the protrusion 51 to pass through the communication hole 43C, the protrusion 51 can pass through the upper through-hole 43B. Thereby, the rear surface (tapered surface 52A) of the locking portion 52 can be locked to the upper through hole 43B from the front (see FIG. 9).

Further, as shown in FIGS. 6 and 7, a lower end of the handle main body 41 is formed with a notch 43 </ b> D that opens downward. A support portion 39 protruding forward from the frame 31A is fitted into the cutout portion 43D. As a result, the handle main body 41 is supported from the support portion 39. In addition, although the support part 39 is comprised by the screw, for example, it is not limited to this. In the present embodiment, in the frame 31 </ b> A, the two handle attachment portions 50, 50 are arranged in the vertical direction, and the attachment holes 43 are respectively formed corresponding to the handle attachment portions 50. The pair of handle attachment portions 50, 50 are also provided on the frame 31B.

  Next, the effect of this embodiment will be described. According to this embodiment, the warming chamber side handle member 40 is detachably attached to the cart body 34. Thereby, when putting the cart 30 in the warm room 11, the warm room side handle member 40 can be removed from the cart main body 34, and the situation where the warm room room side handle member 40 becomes high temperature can be suppressed.

  In the present embodiment, the warm chamber-side handle member 40 can be attached to the handle attachment portion 50 from the front. Specifically, first, the locking portion 52 and the protruding portion 51 are penetrated from the rear side through the lower through hole 43A of the handle main body portion 41 (see FIG. 8). Next, when the handle main body 41 is moved downward, the protruding portion 51 moves to the upper through hole 43B through the communication hole 43C, and is inserted into the upper through hole 43B (see FIG. 7). Thereby, attachment of the warm room side handle member 40 is completed.

  Here, the diameter D3 of the upper through-hole 43B is set smaller than the diameter D2 of the front end of the locking portion 52 and larger than the diameter D6 of the rear end of the locking portion 52. With such a configuration, when the operator pulls the warming chamber side handle member 40 forward with the protrusion 51 inserted through the upper through hole 43B, the hole edge 45B of the upper through hole 43B is engaged. It latches on the rear surface (tapered surface 52A) of the stop part 52 (refer FIG. 7). For this reason, the handle attaching part 50 does not come off from the upper through hole 43B.

  The width D4 of the communication hole 43C is set smaller than the diameter D3 of the upper through hole 43B. For this reason, when the operator tries to raise the warming chamber side handle member 40 while pulling it forward (front side of the worker), the rear surface (tapered surface 52A) of the locking portion 52 communicates from above. It catches on the hole edge 45C (see FIG. 6) of the hole 43C. Thereby, the situation where the handle attaching part 50 moves to the lower through-hole 43A through the communication hole 43C can be suppressed. That is, when the operator operates the warming chamber side handle member 40, the handle mounting portion 50 in the upper through-hole 43B moves to the lower through-hole 43A, and the warmer chamber side is moved from the handle mounting portion 50 to the warming chamber side. The situation where the handle member 40 comes off can be suppressed.

  In the present embodiment, the diameter D6 of the rear end of the locking portion 52 is set to be smaller than the width D4 of the communication hole 43C, and the taper surface 52A in the front-rear direction (left-right direction in FIG. 7) and the front surface 31C of the frame 31A. The minimum distance B1 is greater than the plate thickness B2 of the handle main body 41. For this reason, from the state of FIG. 7, when the warming chamber side handle member 40 is pressed rearward (on the frame 31 </ b> A side) and then moved upward, the tapered surface 52 </ b> A of the locking portion 52 may be caught by the hole edge 45 </ b> C. The rear end of the locking portion 52 and the protruding portion 51 can be moved to the lower through-hole 43A through the communication hole 43C. Thereafter, the handle attachment portion 50 can be removed from the lower through hole 43A by pulling the warming chamber side handle member 40 forward. Thereby, the warm room side handle member 40 can be removed from the handle attaching part 50.

  The handle attachment portion 50 is also provided on the frame 31B of the cart body 34. With such a configuration, the warming chamber side handle member 40 removed from the handle mounting portion 50 on the warming chamber 11 side (frame 31A) can be mounted on the handle mounting portion 50 on the cold storage chamber 12 side (frame 31B). Yes, you can hold this.

Note that FIG. 9 shows a state in which some of the wall portions constituting the station 70 are omitted. The slide base 81 has openings 81A and 81B. A packing 82A (see FIG. 3) is inserted through the opening 81A to close the gap between the outlet passage 74 and the outlet passage 23. A packing 82B that closes the gap between the inlet port 73 and the suction port 24 is inserted through the opening 81B.

  The packings 82A and 82B are formed with air passages penetrating in the vertical direction. The air sent from the lead-out port 74 is blown to the blow-out port 23 through the inside of the packing 82A, and the air sent from the suction port 24 passes through the inside of the packing 82B. It is configured to be sent to the mouth 74. The packings 82A and 82B have a bellows shape and are formed to be extendable and contractable along the axial direction (vertical direction).

  The slide base 81 has a box shape opened upward. As shown in FIGS. 9 and 10, heaters 83 and 83 and heat insulating materials 84 and 84 are provided on the upper surface of the bottom wall of the slide base 81. Each heater 83, 83 is arranged at the edge of the openings 81A, 81B. That is, the heater 83 extends so as to surround the packing 82A and the packing 82B.

  The heat insulating material 84 is a sheet member having water absorption, and is arranged so as to cover the heater 83 from above. Openings 84A and 84B are formed in the heat insulating material 84 so as to correspond to the openings 81A and 81B, respectively. Thus, the packing 82A is inserted through the opening 84A, and the packing 82B is inserted through the opening 84B. In other words, the packing 82 </ b> A and the packing 82 </ b> B are covered with the heat insulating material 84.

Related Art 3 will be described with reference to FIGS. FIG. 11 is a perspective view showing the heat insulation box 20. As shown in FIG. 11, in the top plate 20 </ b> D of the heat insulating box 20, a protrusion 24 </ b> A is formed at the opening edge of the suction passage 24 on the refrigerator compartment 12 side. FIG. 12 is a schematic diagram showing the positional relationship between the packing 82B and the protrusion 24A. The slide base 81 described above is provided so as to be movable up and down, and the packings 82A and 82B expand and contract as the slide base 81 moves up and down. FIG. 12 shows the packing 82B in a state where the slide base 81 is in the raised position. In this state, the lower end of the packing 82B is located away from the top plate 20D. In addition, when the slide base 81 descends in the state of FIG. 12, the lower end of the packing 82 </ b> B descends and contacts the opening edge of the suction passage 24.

  The protrusion 24 </ b> A extends over the entire circumference of the opening edge of the suction passage 24. Further, the protrusion 24A is arranged inside the lower end of the packing 82B. With such a configuration, when the condensed water generated in the packing 82 </ b> B falls on the top plate 20 </ b> D, a situation in which the water drops fall on the suction passage 24 can be suppressed by the protrusion 24 </ b> A. Further, the protruding end of the protrusion 24A is arranged at a position higher than the upper surface of the top plate 20D. For this reason, even if water drops falling from the packing 82B accumulate on the top plate 20D, the water does not get over the protrusion 24A and flows, for example, to the outer peripheral side of the top plate 20D. .

  In addition, 24 A of protrusions may be provided in the blowing outlet 23, and may be provided in the warming chamber 11 side. However, a tray 80 is disposed below the suction port 24 (see FIG. 3). In addition, condensation is relatively likely to occur on the outer surface of the packing 82B on the refrigerator compartment 12 side. For this reason, it is particularly preferable to provide the protrusion 24A at the outlet 23 on the refrigerator compartment 12 side.
