  Moreover, in the auxiliary electric distribution vehicle 1 of the present embodiment, as shown in FIG. 2, the resin cover 31 that covers and conceals the battery 42 is from the steel plate top plate 6 placed on the upper surface of the main body 102. Also small and light. In this regard, in consideration of the fact that the battery 42 is conventionally arranged in the interior (machine room) covered by the top plate 6 (see the “Background Art” column), when the battery 42 is replaced, Even if the removed resin cover 31 is placed on the floor or leaned against the wall, it does not bother the surrounding people.

  Furthermore, considering the fact that a refrigeration device is conventionally arranged in the interior (machine room) covered with the top plate 6 (see the section “Background Art”), the auxiliary electric motor of the present embodiment The attachment of the battery 42 to the one side surface 21 of the main body 2 as in the case of the type allocation vehicle 1 means that the battery 42 is disposed at a position away from the refrigeration apparatus, and the battery 42 is influenced by the heat of the refrigeration apparatus. It can be said that it has stopped receiving.

In addition, the auxiliary electric trolley 1 according to the present embodiment is equipped with an ozone deodorizing device. However, since this ozone deodorizing device uses ozone gas, it can be used safely from the viewpoint of using it. Therefore, it is requested to use the following carefully. First, when operating the ozone deodorizing apparatus, the ozone deodorizing apparatus is operated after the door 3 is closed tightly in order to prevent a large amount of ozone from leaking out of the main body 2. And when the ozone deodorizing apparatus is operated, the door 3 is not opened. Further, when operating the ozone deodorizing apparatus, the main body 2 is not as close as possible. Furthermore, when the ozone deodorizing apparatus is operated, the room is sufficiently ventilated.

However, if you leave the user Mau, carelessness and the like, without closing the door 3 firm, or to operate the ozone deodorizing system, also, when you are running the ozone deodorizing system, or open the door 3 The situation where the precautions are not observed cannot be completely eliminated.

  Therefore, in the auxiliary electric trolley 1 according to the present embodiment, the ozone deodorizing device is prevented from operating when the door 3 is open. Therefore, as shown in FIG. 15, a contact type door switch 61 is installed between the main body 2 and each door 3. In this regard, as shown in FIG. 16, each contact type door switch 61 is in a state where the contact 62 is pushed down by the door 3 and turned on when the door 3 is completely closed, as shown in FIG. In addition, when the door 3 is opened even a little, the contact 62 is separated from the door 3 and turned off.

  FIG. 15 is a view of the main body 2 and one door 3 as viewed from the side. FIGS. 16 and 17 are views of the main body 2 and one door 3 as seen from above, with a top plate 6 (for example, see FIG. 2) not shown in the drawings removed.

  Then, like the wiring diagram shown in FIG. 18, the switching regulator SR, the ozonizers OZ1 and OZ2, the ozonizer operation time setting timer TM1, the ozone concentration adjusting timer TM2, the power switch S1 of the ozone deodorizing device, and the contact switches S2, Build circuits for S3, S4 and S5.

  Thus, if even one door 3 is open, even if the power switch S1 of the ozone deodorizing apparatus is turned on, the ozone deodorizing apparatus is not energized, so the ozone deodorizing apparatus does not operate. On the other hand, if all the doors 3 are closed, then when the power switch S1 of the ozone deodorizing apparatus is turned on, the ozone deodorizing apparatus is energized, and thus the ozone deodorizing apparatus operates. Furthermore, if any one of the doors 3 is opened while the ozone deodorizing apparatus is in operation, any one of the contact switches S2, S3, S4, S5 is immediately turned off, and the energization to the ozone deodorizing apparatus is interrupted. Therefore, the operation of the ozone deodorizer stops.

  Each door switch 61 uses a contact type in which the contact 62 is directly pressed by the door 3, but in this respect, if it can be determined that the door 3 is completely closed, A non-contact type may be used.

As described above, in the auxiliary electric distribution vehicle 1 of the present embodiment, if any one of the doors 3 is in an open state, the operation of the ozone deodorizing device is not performed, so that ozone gas leaks to the outside of the main body 2. It doesn't happen.
Further, even if the door 3 is opened during the operation of the ozone deodorizing apparatus, the operation of the ozone deodorizing apparatus is immediately stopped, so that the ozone gas already existing in the main body 2 does not leak out of the main body 2. Although there is, a large amount of ozone gas does not leak out of the main body 2.
However, by installing a contact type door switch 61 between the main body 2 and each door 3, the point that the ozone deodorizing device does not operate when the door 3 is open is the same even in a manual barge. It is.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning.
For example, in the auxiliary electric trolley 1 according to the present embodiment, in order to prevent the ozone deodorizing apparatus from operating when the door 3 is open, as shown in FIG. The contact type door switch 61 is installed in the. In this regard, as shown in FIG. 19, an automatic key 71 may be installed between the main body 2 and each door 3 so that the ozone deodorizing device does not operate when the door 3 is opened.

  Therefore, each automatic key 71 is allowed to operate on the condition that it is detected that each door 3 is in a closed state. Furthermore, according to a wiring diagram described later, each automatic key 71 is When turned on, the motor built in each automatic key 71 is activated / stopped, and as shown in FIG. 20, the locking portion 71A of each automatic key 71 and the locking portion 3A of each door 3 interfere with each other. Thus, it is possible to lock the doors 3 so that they cannot be opened. When the switch is turned off, the motor built in each automatic key 71 is activated and stopped, and as shown in FIG. 21, the locking portion 71A of each automatic key 71 and the locking portion 3A of each door 3 By releasing the interference, the key can be opened so that each door 3 can be opened.

  FIG. 19 is a cross-sectional view of the main body 2 and one door 3 as viewed from the side. 20 and 21 are views in which the main body 2 and the two doors 3 are viewed from the front direction with a part of the top plate 6 cut away.

  Then, like the wiring diagram shown in FIG. 22, the switching regulator SR, the ozonizers OZ1 and OZ2, the ozonizer operation time setting timer TM1, the ozone concentration adjusting timer TM2, the power switch S1 of the ozone deodorizing apparatus, and the automatic key opening / closing switch S2, circuits for the automatic key closing relay X1, the automatic key opening relay X2, and the automatic key opening / closing motors GM1, GM2, GM3, GM4 are constructed.

  Thereby, if the automatic key 71 is open, even if the power switch S1 of the ozone deodorizing device is turned on, the ozone deodorizing device is not energized, so the ozone deodorizing device does not operate. On the other hand, if the automatic key 71 is engaged, when the power switch S1 of the ozone deodorizing device is turned on after that, the ozone deodorizing device is energized and thus the ozone deodorizing device operates. Furthermore, if the automatic key 71 is opened while the ozone deodorizing apparatus is in operation, the energization of the ozone deodorizing apparatus is immediately interrupted, and the operation of the ozone deodorizing apparatus stops.

  All the automatic keys 71 can be operated simultaneously by the automatic key opening / closing switch S2. However, in this respect, a switch or a sensor that can determine that each door 3 is completely closed is installed. If the circuit is constructed so that the ozone deodorizing apparatus is operated only when 3 is completely closed, each automatic key 71 may be individually operated.

From the above, in the auxiliary electric wheeled vehicle 1 of the present embodiment, the operation of the ozone deodorizing device is not performed if the automatic key 71 is present, so that ozone gas leaks out of the main body 2. Does not occur.
Further, even if the automatic key 71 is opened during the operation of the ozone deodorizing apparatus, the operation of the ozone deodorizing apparatus is immediately stopped, so that the ozone gas already existing in the main body 2 does not leak out of the main body 2. Although there is, a large amount of ozone gas does not leak out of the main body 2.
Of course, by installing an automatic key 71 between the main body 2 and each door 3, the point that the ozone deodorizing device does not operate when the door 3 is open is the same even in a manual barge. .
