(Mechanism for cleaning)
First, the cleaning mechanism in the cleaning / drying apparatus 10 will be described. FIG. 6 is a plan view showing a liquid supply system of the cleaning / drying apparatus 10, that is, a liquid supply means for supplying the cleaning liquid into the cleaning tank 24 when cleaning the object to be cleaned. FIG. 7 is a cross-sectional view seen from the front side of the washing / drying apparatus main body 11 showing the liquid supply system. In this cleaning / drying apparatus 10, cleaning liquid tanks 25, 28 that store cleaning liquid and liquid supply pumps 26, 29 for sending the cleaning liquid are externally attached to the cleaning / drying apparatus body 11. One cleaning liquid tank and one liquid supply pump may be provided, and there may be three or more, but in the following, a case where there are two cleaning liquid tanks will be described. The liquid supply pumps 26 and 29 can be built in the cleaning / drying apparatus main body 11, but the cleaning / drying apparatus main body 11 can be made compact by being installed outside the cleaning / drying apparatus main body 11, and can be installed at the installation location. The optimum arrangement can be selected accordingly. In addition, by installing the cleaning liquid tanks 25 and 28 outside the cleaning / drying apparatus main body 11, it becomes easy to supply the cleaning liquid and clean the cleaning liquid tanks 25 and 28.

  Different types of cleaning liquid are stored in the cleaning liquid tank 25 and the cleaning liquid tank 28. For example, the cleaning liquid tank 25 may store cleaning water (warm water), and the cleaning liquid tank 28 may store solvent-based cleaning liquid. A hot water heater 31 and a temperature sensor (not shown) for heating the cleaning liquid are provided in the cleaning liquid tank 25, and the cleaning liquid in the cleaning liquid tank 25 is maintained at a substantially constant temperature. In addition, a water level sensor may be provided in the cleaning liquid tank 25 to notify when the cleaning liquid is below a predetermined water level. Reference numeral 32 denotes a waste liquid pipe for discarding the cleaning liquid in the cleaning liquid tank 25. The cleaning liquid tank 28 may be provided with a heater, a temperature sensor, a water level sensor, and a waste liquid pipe as necessary.

  The lower part of the side surface of the cleaning liquid tank 25 and the liquid supply pump 26 are connected by a liquid supply pipe 27a, and the liquid supply pipe 27b having one end connected to the liquid supply pump 26 is connected to the cleaning / drying apparatus from the back of the cleaning / drying apparatus body 11. It is led into the main body 11 and is connected to one inflow end of the merging pipe 33 installed in the washing / drying apparatus main body 11. The liquid supply pipe 27a includes a water stop valve 34a, and the liquid supply pipe 27b includes a filter 35 for removing dust and dirt, a water stop valve 34b, and an electromagnetic opening / closing valve 36.

  Similarly, the lower part of the side surface of the cleaning liquid tank 28 and the liquid supply pump 29 are connected by a liquid supply pipe 30 a, and the liquid supply pipe 30 b having one end connected to the liquid supply pump 29 is connected to the rear surface of the cleaning / drying apparatus main body 11. It is led into the washing / drying device main body 11 and connected to the other inflow end of the junction pipe 33 installed in the washing / drying device main body 11. The liquid supply pipe 30b includes a water stop valve 37a, a filter 38 for removing dust and dirt, a water stop valve 37b, and an electromagnetic opening / closing valve 39. The water stop valves 34a, 34b, 37a, 37b are always open.

  The liquid supply pipe 40 connected to the outflow end of the junction pipe 33 is connected to the rotating shaft 16a, and the rotating shaft 16a also constitutes a part of the liquid supply system. That is, the cleaning liquid sent from the liquid supply pipe 40 is injected into the water supply space 64a through the inside of the rotating shaft 16a. The liquid supply pipe 40 and the rotating shaft 16a may be formed integrally.

  Next, the swing mechanism 41 for swinging the container 19 will be described. The swing mechanism 41 is configured by a crank mechanism, a power transmission unit, and a motor 48 as shown in FIGS. The crank mechanism is configured such that the other end of the first crank rod 43 fixed at one end to the rotating shaft 42 and one end of the second crank rod 44 are rotatably coupled by a pin 45. The other end is connected to a pin 46 (see FIG. 4) provided on the outer surface of the swing box 17. The power transmission unit is wound around the driven pulley 47 fixed to the rotating shaft 42 outside the drainage tank 12, the driving pulley 49 fixed to the shaft of the motor 48, and the driven pulley 47 and the driving pulley 49. The chain 50 is constituted.

  Thus, when the motor 48 is driven, the rotary shaft 42 rotates in one direction at an appropriate rotational speed via the driving pulley 49, the chain 50, and the driven pulley 47. As a result, as shown in FIGS. 9A to 9D, the swinging box 17 is repeatedly swung left and right by the action of the crank mechanism.

  FIG. 10 is a cross-sectional view showing a drainage system of the cleaning / drying apparatus 10. FIG. 11 is a schematic plan view showing a drainage system of the cleaning / drying apparatus 10. This drainage system will be described. As shown in FIG. 10, a recovery pipe 51 is connected to the drainage port 13 on the bottom surface of the drainage tank 12, and the recovery pipe 51 branches into a recovery pipe 52a and a recovery pipe 52b as shown in FIG. is doing. The recovery pipe 52a is connected to the upper part of the cleaning liquid tank 25, and the recovery pipe 52a includes an electromagnetic opening / closing valve 53a. The recovery pipe 52b is connected to the cleaning liquid tank 28, and the recovery pipe 52b includes an electromagnetic opening / closing valve 53b.

  Therefore, if the electromagnetic opening / closing valve 53b is closed and the electromagnetic opening / closing valve 53a is opened, the cleaning liquid dropped into the drainage tank 12 is recovered into the cleaning liquid tank 25 through the recovery pipes 51 and 52a. On the contrary, if the electromagnetic opening / closing valve 53a is closed and the electromagnetic opening / closing valve 53b is opened, the cleaning liquid dropped into the drainage tank 12 is recovered into the cleaning liquid tank 28 through the recovery pipes 51 and 52b.

(Cleaning operation)
An operation of cleaning the object to be cleaned 18 by the cleaning / drying apparatus 10 having the above structure will be described. As shown in FIG. 12, after the container 19 containing the dry matter 18 to be cleaned is set in the cleaning tank 24 of the swing box 17 and the lid 15 is sealed, the electromagnetic switching valve 36 is kept closed with the electromagnetic switching valve 39 closed. When the liquid supply pump 26 is operated, the cleaning liquid α in the cleaning liquid tank 25 is injected into the water supply space 64a of the swing box 17 from the rotary shaft 16a through the liquid supply pipes 27a, 27b and 40, and the bottom portion. It accumulates in the space 64c. Since the leak hole 66 is opened in the bottom surface of the bottom space 64c, a part of the cleaning liquid α leaks into the drainage tank 12 from the leak hole 66, but the flow rate of the cleaning liquid α supplied from the rotary shaft 16a is reduced. Therefore, the water level of the cleaning liquid α in the rocking box 17 gradually rises. As a result, the cleaning liquid α enters the container 19 from the bottom through the bottom opening 65, and the dry matter 18 to be cleaned is immersed in the cleaning liquid α accumulated in the container 19.

  If the dry matter 18 to be cleaned is completely immersed in the cleaning liquid α after a predetermined time has elapsed, the flow rate of the cleaning liquid α injected from the rotating shaft 16a is controlled to be substantially equal to the leakage flow rate from the leakage hole 66. The water level in 19 can be maintained at a substantially constant height.

  Alternatively, as shown in FIG. 13, the flow rate of the cleaning liquid α injected from the rotating shaft 16 a may be left as it is, and the cleaning liquid α may be allowed to overflow from the upper surface of the container 19 into the drainage tank 12. If the cleaning liquid α continues to overflow as shown in FIG. 13, the cleaning liquid α passes through the container 19 and is replaced with a new cleaning liquid α, so that the cleaning effect of the object to be cleaned 18 is enhanced. Further, the flow rate control of the cleaning liquid α can be simplified. Therefore, the method as shown in FIG. 13 is preferable.

  On the other hand, in the drainage system, the electromagnetic on-off valve 53b is closed and the electromagnetic on-off valve 53a is opened, so that the cleaning liquid α leaking from the leak hole 66 and the cleaning liquid α overflowing from the container 19 are collected from the drain port 13 through the recovery pipe. 51, and further immediately recovered into the original cleaning liquid tank 25 through the recovery pipe 52a.

  Thus, when the dry matter 18 to be cleaned is completely immersed in the cleaning liquid α, the motor 48 is activated to drive the swing mechanism 41, and the swing box 17 is moved as shown in FIGS. Oscillate repeatedly. As a result, the container 19 holding the dry matter 18 to be cleaned is swung, and the dry matter 18 to be cleaned in the container 19 is swung in the cleaning liquid α, so that fine dust and dirt adhering to the dry matter 18 to be cleaned are swung. Drugs are rinsed off. That is, when the container 19 is swung, the cleaning liquid α flows between the objects to be cleaned 18 and is attached to the surface of the objects to be cleaned 18 or dust or dirt that has entered the gaps between the objects to be cleaned 18. Etc. can be liberated and cleaning can be performed effectively.

  When the cleaning process is completed, the motor 48 is turned off and the swing box 17 is stopped. Further, the liquid supply pump 26 is stopped and the electromagnetic opening / closing valve 36 is closed to stop the supply of the cleaning liquid α. When the supply of the cleaning liquid α is stopped, as shown in FIG. 14, the cleaning liquid α in the container 19 is discharged from the bottom opening 65 to the bottom space 64c, and the cleaning liquid α in the swing box 17 is discharged from the leak hole 66 to the drain tank. 12 is discharged. The cleaning liquid α discharged to the drainage tank 12 is recovered to the original cleaning liquid tank 25 through the recovery pipes 51 and 52a. Thus, when the cleaning liquid α in the container 19 and the bottom space 64c has been discharged to the drainage tank 12, and after the cleaning liquid α in the drainage tank 12 has been discharged and collected in the cleaning liquid tank 25, the electromagnetic opening / closing valve 53a is closed. .

  In the above description, the case where cleaning is performed using the cleaning liquid in the cleaning liquid tank 25 has been described, but the same applies to the case where cleaning is performed using the cleaning liquid in the cleaning liquid tank 28. It is also possible to perform the cleaning twice or more by performing cleaning with one cleaning liquid in the cleaning liquid tanks 25 and 28 and then further cleaning with the other cleaning liquid.

(Mechanism and operation for drying)
Next, a structure for drying in the washing and drying apparatus 10 will be described. The cleaning / drying apparatus 10 performs suction drying and hot air drying. As shown in FIG. 3, the mechanism for suction drying is mainly composed of a suction duct 59, a suction branch duct 60, a rotating shaft 16 b and a blower 55. The upper end of the suction duct 59 is connected to the hollow rotating shaft 16 b, and the lower end of the suction duct 59 is located immediately above the tray 61. A suction branch duct 60 branches in a horizontal direction slightly above the lower end of the suction duct 59, and the other end of the suction branch duct 60 is connected to a suction blower 55. An electromagnetic opening / closing valve 62 is provided at the upper end of the suction duct 59. A check valve 67 is provided at the lower end of the suction duct 59 (below the portion where the suction branch duct 60 branches). The check valve 67 is configured to be closed when the blower 55 is operated and the upper side becomes negative pressure, and is opened when the blower 55 is stopped and the upper side becomes normal pressure.

  As shown in FIG. 10, the cleaning / drying apparatus 10 includes an air heater 56 such as an electric heater for drying hot air. The air heater 56 heats the air that has entered from the air intake port on the lower surface and supplies it from the discharge port on the upper surface, and is provided with a filter at the air intake port. Further, a hot air outlet 54 is opened in the upper part of the drainage tank 12, and the discharge port of the air heater 56 and the hot air outlet 54 are connected by a hot air duct 57.

  Therefore, when the drying operation is performed after the cleaning process, the electromagnetic opening / closing valve 62 of the suction duct 59 is opened and the air heater 56 and the blower 55 are operated. When the blower 55 is operated, air in the suction drying space 64b and the bottom space 64c is sucked, and the sucked air is exhausted from the exhaust duct 58 of the blower 55 to the outside through the suction duct 59 and the suction branch duct 60. Is done.

  At the start of the drying operation, the surface of the object to be cleaned 18 is wet with the cleaning liquid α, and the cleaning liquid α is held in the gap between the objects to be cleaned 18 by surface tension. On the other hand, since the gap around the lower surface of the container 19 is closed by the elastic sheet 63, when the bottom space 64c, the suction drying space 64b, and the like become negative pressure, as shown in FIG. The cleaning liquid α adhering to the surface and the cleaning liquid α held in the gap between the objects to be cleaned 18 are drawn downward and sucked into the suction duct 59 from the rotary shaft 16b. Since the check valve 67 is closed when the blower 55 is in operation, the cleaning liquid α out of the cleaning liquid α (fine moisture) and air sucked into the suction duct 59 is separated from the air by inertia and the lower end of the suction duct 59 It collects in. Further, the air separated from the cleaning liquid α passes through the blower 55 and is discharged from the exhaust duct 58 to the outside. Most of the cleaning liquid adhering to the surface of the dry object to be cleaned 18 and the cleaning liquid held in the gap between the dry objects to be cleaned 18 are drawn from the bottom surface opening 65 within several tens of seconds after the operation of the blower 55 is started. It is pulled out and falls to the lower end of the suction duct 59, and this phenomenon (suction drying) ends when several tens of seconds have elapsed from the start of operation of the blower 55.

  When the extraction (suction drying) of the cleaning liquid α adhering to the surface of the dry object 18 to be cleaned and the cleaning liquid α held in the gap between the dry objects 18 to be cleaned is completed, the blower 55 is once stopped. When the blower 55 is stopped, the check valve 67 is opened, so that the cleaning liquid α accumulated at the lower end of the suction duct 59 is discharged to the tray 61. When the cleaning liquid α is completely discharged to the tray 61, the operation of the blower 55 is started again.

  On the other hand, during the drying operation, air is sucked into the drainage tank 12 from the hot air outlet 54 due to the suction force of the blower 55, but the heater temperature of the blower 55 rises as soon as the heating operation starts. The temperature of the hot air blown out from the outlet 54 rises, and accordingly, the temperature in the drainage tank 12 rises and becomes high. However, the hot air temperature is detected by a temperature sensor (not shown), and the temperature is controlled so as to be stabilized at a substantially constant temperature. This hot air temperature can be set in advance on the operation panel according to the quantity and shape of the object to be cleaned 18, and is usually set within a range of 60 ° C. to 90 ° C. Then, air is sucked from the rotating shaft 16b after the suction drying, so that hot air passes through the cylindrical body 19a of the container 19 from top to bottom, and the dry matter 18 to be cleaned in the container 19 is kept for a predetermined time. It is dried with warm air.

  After performing the drying operation for a predetermined time in this way, the air heater 56 is turned off to end the drying operation. After the drying operation is finished, the blower 55 is operated for a while to cool the dry matter 18 to be cleaned with cold air. When a predetermined time has elapsed, the blower 55 is also stopped and the electromagnetic opening / closing valve 62 is closed.

  When the object to be cleaned 18 is dried, the lid 15 is opened, the handle 22 of the container 19 is grasped, and the container 19 is taken out from the cleaning tank 24. Normally, at this time, the lower surface of the container 19 often has water droplets or gets wet. However, in this embodiment, the elastic sheet 63 having water absorbability is brought into contact with the lower surface of the container 19. The moisture on the lower surface of 19 is absorbed by the elastic sheet 63, and the lower surface of the taken-out container 19 does not get wet.

  According to such a cleaning / drying apparatus 10, since it is possible to clean and dry the object to be cleaned with one apparatus, two apparatuses, a cleaning apparatus and a drying apparatus, are required as in the past. Can be replaced with a single washing / drying apparatus, and the installation space can be reduced and the apparatus cost can be reduced. In addition, it is not necessary to transport the container containing the material to be cleaned to the drying device after washing the material to be cleaned with the cleaning device as in the past. In particular, it is possible to wash and dry the object to be washed.

(Second Embodiment)
FIG. 17 is a schematic plan view showing a liquid supply system of a hot water washing and drying apparatus 71 according to Embodiment 2 of the present invention. In this embodiment, the inside of the liquid storage tank 72 is partitioned by a partition plate 73, one of which is a cleaning liquid tank 25 and the other is a cleaning liquid tank 28.

  According to this embodiment, since the plurality of cleaning liquid tanks 25 and 28 are constituted by one liquid storage tank 72, the hot water cleaning and drying apparatus 71 can be made compact.

(Other embodiments)
Since the leak hole 66 is a small hole, the windage loss due to the leak hole 66 when sucked by the blower 55 is small, but it opens when water pressure is applied to the bottom space 64c, and the inside of the bottom space 64c is negative pressure. If a valve (valve film) that closes when the valve is in the leak hole 66 is provided, windage damage due to the leak hole 66 can be prevented. Alternatively, a mechanism for opening and closing the leakage hole 66 is provided. When the cleaning liquid α in the bottom space 64c is discharged, the leakage hole 66 is opened. When the blower 55 makes the pressure in the bottom space 64c negative, the leakage hole 66 is opened. You may make it close.
