<Means for Solving the Problems> In order to achieve the above-mentioned object, the dish disinfection storage unit with a lifting shelf of the present invention is provided with a plurality of shelves capable of moving up and down in a storage room to be heated, and the shelves are driven by a motor. In a dish disinfection storage cabinet with a lifting shelf that is moved up and down by driving, an operation panel with a switch for operation is separated from a control panel that controls the drive of the motor through a cord, and a magnet or suction cup is provided on the back of the operation panel. To be done.

<Operation> When a tableware basket containing a large number of tableware is to be stored in the storage room of the storage, the door is opened and the operation panel is adsorbed to an appropriate place inside the door (which is substantially facing the front). In this state, place the tableware basket on the lowest shelf and store the tableware basket while raising the shelves in order, but in this case, the operation panel of the elevating shelf is adsorbed on the inside of the door where it is easy to touch. Therefore, it is possible to easily operate the switch of the operation panel while inserting the tableware basket, and perform the work while raising the shelves one by one. Even when removing the tableware basket from the storage room, the operation panel can be adsorbed on the inside of the door and work can be conveniently performed in the same manner.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a front view of a dish disinfection storage cabinet with lifting shelves, and FIG. 2 shows a right side view thereof. A double-opening door 2 is provided on the front surface of the storage box main body 1 formed in a vertically long box shape, and a storage chamber 3 is formed inside the door 2.

As shown in the cross-sectional view of FIG. 3, a hot air passage 4 provided with a heater 6 is vertically formed on a side portion of the storage chamber 3, and a blower 5 is provided at a part of a ceiling portion communicating with the hot air passage 4 in the storage chamber. It is provided so that the air in 3 is sucked and sent to the hot air passage 4.

A large number of air supply holes 7 are provided at the bottom of the storage chamber 3, and the hot air sent from the hot air passage 4 is sent into the storage chamber 3 from the holes 7. As the heater 6, an electric heater or a heat exchanger that heats steam as a heat medium is used.

An elevating shelf is provided in the storage room 3. This elevating shelf is
The plurality of stacked shelves 8 are connected by four connecting strings 9 each having a constant length, the ends of the hoisting strings 10 are connected to the four corners of the uppermost shelf 8, and the ends of the four hoisting strings 10 are connected. Is fixed to the pulley of the hoisting machine 11 provided on the ceiling and is wound. The hoisting machine 11 is driven by a motor M with a speed reducer, and its drive control circuit is constructed as shown in FIG. 6 and is installed in a control panel 12 mounted on the side of the main body.

In the control circuit of FIG. 6, MC1 is an electromagnetic switch for rotating the motor M in the shelf lowering direction, MC2 is an electromagnetic switch for rotating the motor M in the shelf rising direction, and TM1 is for automatically stopping when the shelf is lowered by one step. Timer relay, TM2 is a timer relay for automatically stopping when the shelf is raised by one step, SW
1 is a descending switch, SW2 is an ascending switch, TS1 and T
S2 is a timer relay for using the switches SW1 and SW2 also as stop switches, and LS1 and LS2 are limit switches which are turned on at the rewinding end and the winding end of the hoisting machine 11.

The time of the timer relays TM1 and TM2 is set to a time for which the hoisting machine 11 raises or lowers the shelf 8 by one step, for example, 3 seconds, and the time of the timer relays TS1 and TS2 is set to a short time, for example, 1 second or less. .

The descending switch SW1 and the ascending switch SW2 are the control panel 1
Small operation panel 1 pulled out from 2 via cord 15
4 (FIG. 4), this code 15 is used for the control panel 12
To the front of the ceiling through the inside of the main body, and hangs downward from the front of the main body 1 via the latch arm. Further, a magnet (rubber magnet) 16 is fixed to the back surface of the operation panel 14, so that the operation panel 14 can be attracted to the front surface of the door 2 or an arbitrary position inside thereof.

Since the door 2 is usually made of stainless steel, it can be attracted by a magnet. However, in the case of a door that does not attract a magnet, a suction cup can be fixed to the back surface of the operation panel 4 so that the door 2 can be attracted. Further, the cord 15 of the operation panel 14 may be pulled out directly from the front side of the control panel 12 to the front side of the main body 1 as shown by the phantom line in FIG.

When storing tableware in the tableware disinfecting storage configured as described above, first, the double door 2 is opened. At this time, the operation panel 14 adsorbed on the front surface of the door 2 is removed, and the opened door 2 is opened.
It is adsorbed to a place that is easy to touch inside (Fig. 5). This makes it possible to easily switch the operation panel 14 even when the door 2 is open.

Then, the tableware basket containing the tableware is placed on the shelf 8 in the lowered position in the storage chamber 3. Then, the ascending switch SW2 on the operation panel 14 is pressed. Then, in the control circuit of the motor M, the timer relay TS2 turns on its contact after an extremely short delay time, the electromagnetic switch MC2 closes, and self-holding is performed by turning on the contact, and the motor M moves up the shelf 8. Then, the winding machine 11 is rotationally driven. And shelves 8
Rises by one stage, the timer relay TM2 performs a timed operation and turns off the timed contact. As a result, the motor M is stopped and the shelf 8 automatically stops rising. Then, the tableware basket is placed on the empty shelf 8 and the lifting switch SW2 is operated again, and the shelf 8 is further raised by one step as described above.

In this way, when the tableware is completely loaded, the operation panel 1
4 is removed from the inside of the door 2, the door 2 is closed, and the operation panel 14 is adsorbed on the front surface of the door 2.

On the other hand, when the tableware is taken out from the storage, the door 2 is opened, the operation panel 14 is adsorbed to the inside of the door 2 in the same manner as above, and the tableware basket is taken out from the lowest shelf 8. Then, the lowering switch SW1 of the operation panel 14 is pushed to lower the shelf. In the control circuit of the motor M, the timer relay TS1 turns on its contact after an extremely short delay time, and the electromagnetic switch MC1
Is closed, and another contact is turned on to perform self-holding, and the motor M rotationally drives the winding machine 11 in the direction of lowering the shelf 8. Then, when the shelf 8 descends by one step, the timer relay TM1 performs a timed operation and turns off the timed contact. As a result, the motor M stops, and the shelf 8 automatically stops lowering. Then, the tableware basket is taken out from the shelf 8 located at the lowest position again, and the lowering switch SW1 is operated again, and the shelf 8 is further lowered by one step as described above.

When the shelf 8 is raised or lowered to come into contact with some obstacle or the like to stop the emergency, the descending switch SW1 is momentarily pushed when the shelf 8 is rising, and the rising switch SW2 is momentarily pushed when the shelf 8 is descending. That is, during the ascent, the descending switch SW
When 1 is turned on, its b contact is turned off, which turns off the electromagnetic switch MC2, so that the motor M is stopped. If the ascending switch SW2 is turned on while descending,
The b contact of the electromagnetic switch MC1 is turned off.
Is turned off, the motor M is stopped. In this case, the ON time of the switches SW1 and SW2 is the timer relay TS1,
Since it is shorter than the set delay time of TS2, the motor is not restarted.

Thus, the ascending switch SW2 and the descending switch SW1
Since it also serves as a stop switch, it suffices to provide the operation panel 14 with two ascending and descending switches.
4 can be made compact and light.

<Effects of the Invention> As described above, according to the dish disinfection storage cabinet with the lifting shelves of the present invention, a plurality of shelves are provided so as to be able to move up and down in the heated storage chamber, and the shelves are moved up and down by the motor drive. In the tableware disinfection storage with shelves, the operation panel with the switch for operation is separated from the control panel that controls the drive of the motor through the cord, and the magnet or suction cup is provided on the back of the operation panel, so the door is When opening and removing tableware from the storage room, even if the control panel provided on the side of the main body enters the back side of the door, the operation panel should be adsorbed to the inside of the door where it is easy to operate. Therefore, it is possible to easily operate the switch of the operation panel to raise and lower the elevating shelf and to take in and out the dishes.
