The second regulating valve 17 is weighted in the direction in which the first regulating valve 16 is closed in a state where the first regulating valve 16 is closing the first passage 11.

With such a configuration, the external air blown into the cleaning tank 11 through the first path 11 and the outside air blown into the second blowing path 12 through the third path 13 during the drying operation. Since the flow rate ratio can be appropriately distributed, it is possible to reliably prevent the hot air sensation caused by the exhaust air having reduced temperature and humidity and to improve the drying performance.

Next, the detailed structure of the dish washing dryer of this embodiment is demonstrated.

Moreover, the blowing part 6 is provided in the bottom part of the outer wall of the washing tank 1. As shown in FIG. The blower 6 blows outside air into the washing tank 1 in order to discharge the air in the washing tank 1 and to dry the inside of the washing tank 1. Moreover, the exhaust port 7 which discharges the air in the washing tank 1 is provided in the upper part of the front surface of a dish washing dryer. The exhaust opening 7 is provided with an exhaust assisting portion 8 for mixing external air. In the lower part of the washing tank 1, an inlet 9 through which outside air is introduced is provided, and an outlet 10 through which air in the washing tank 1 is discharged is provided above.

A first path 11 communicating with the blower 6 and the cleaning tank 1 is provided on the outer wall of the bottom of the cleaning tank 1, and the cleaning tank 6 is removed from the blower 6 through the first path 11. Supply external air to (1). In addition, the air in the cleaning tank 1 is exhausted to the exhaust port 7 through the second path 12 communicating the exhaust port 7 and the cleaning tank 1. Moreover, the 3rd path 13 which branches off from the 1st path 11 and connects to the 2nd path 12 is substantially in front of the washing tank 1 It is arranged in the vertical direction. External air is supplied from the air blower 6 to the second path 12 through the third path 13. Moreover, in the mixing part 14 where the 2nd path 12 and the 3rd path 13 cross | intersect, air exhausted from the washing tank 1 and external air mix.

The 1st path | route 11 and the 3rd path | route 13 are sealed and fixed so that water leakage etc. do not arise in the outer wall of the front surface of the washing tank 1 with welding by vibration, etc., or through seal packing.

The air volume distribution part 15 is provided in the branch part which the 3rd path 13 branches from the 1st path 11. The air volume distribution unit 15 includes a first control valve 16 whose opening degree changes due to the air pressure of the outside air supplied from the air blowing unit 6, near the branch in the middle of the first path 11, Similarly, the 2nd control valve 17 whose opening degree changes with wind pressure is provided in the vicinity of the branch part of the 3rd path | route 13. As shown in FIG. Moreover, the air volume distribution part 15 has the connection body 19 which integrated the 1st control valve 16, the 2nd control valve 17, and the rotary bearing 18 near those engaging parts. The rotary bearing 18 is inserted into the rotating shaft 20 which protrudes substantially horizontally from the wall surface of the air volume distribution part 15, and the connecting body 19 is axially supported by the rotation freely. Moreover, the protrusion part 16a is provided in the front-end | tip of the surface of the blower part 6 side of the 1st control valve 16. As shown in FIG.

The air flow rate distribution unit 15 changes the openings of the first control valve 16 and the second control valve 17 in association with the air pressure of the external air supplied from the blower unit 6, respectively, The mixing ratio of the outside air in 14) and the air exhausted from the cleaning tank 1 is changed.

Specifically, the connecting body 19 is configured such that the opening degree of the first control valve 16 decreases when the opening degree of the second control valve 17 increases. At the time of stopping the operation of the blower 6, the first passage 11 is closed because the first regulating valve 16 is substantially horizontal, and the main body 17a of the second regulating valve 17 is closed. It is substantially perpendicular, and the wind supplied from the blowing section 6 flows mainly in the third path 13. Further, the front end of the second regulating valve 17 is bent from the main body portion 17a in a substantially vertical state to the partition walls of the first path 11 and the third path 13, that is, in the clockwise direction in FIG. 2. The bent part 17b is provided. By this structure, in the state in which the 1st control valve 16 is closing the 1st path | route 11, the 2nd control valve 17 is weighted in the direction which closes the 1st control valve 16, and a blower part ( When the wind pressure of 6) is lower than a predetermined value or when the blower 6 stops operating, the moment acts in the direction to close the first regulating valve 16, that is, in the clockwise rotation direction in FIG.

Moreover, the air volume distribution part 15 forms a part of each of the 1st path | route 11 and the 3rd path | route 13, and is provided so that attachment or detachment is possible with respect to those path | route. Specifically, the wall surface of the air volume distribution part 15 forms a part of the wall surface of a path | route, and is screwed to the path | route vicinity of a branch part. With such a configuration, even if a defect occurs in the air volume distribution unit 15, such as when the first control valve 16 or the second control valve 17 is stuck due to grease or the like, the air volume distribution unit 15 is held. Maintenance can be performed easily by removing and repairing or replacing.

Moreover, although the center of the rotation bearing 18 is formed in the circumferential shape of a cavity, the inner wall of the 3rd path 13 near a branch part is formed in circular arc shape centering on the circumference. As a result, the pressure loss of the external air supplied from the blower section 6 to the third route 13 is reduced by keeping the flow path area of the third route 13 constant from the branch to the predetermined distance.

Moreover, the shielding rib 21b which the one end of the 1st control valve 16 contacts is provided in the wall surface of the air volume distribution part 15 in the state in which the 1st control valve 16 is closed. By such a configuration, the gap between the first control valve 16 and the wall surface of the air volume distribution unit 15 is filled, and in the state where the first control valve 16 is closed, the path from the first control valve 16 is routed. The amount of outside air leaking can be reduced.

Similarly, the shielding rib 21a which the one end of the 2nd control valve 17 contacts is provided in the wall surface of the air volume distribution part 15 in the state in which the 2nd control valve 17 is closed. By such a configuration, the gap between the second control valve 17 and the wall surface of the air volume distribution unit 15 is filled, and the path from the second control valve 17 is closed in the state where the second control valve 17 is closed. It is possible to reduce the amount of external air leaking into the air.

In addition, the washing tank 1 is connected to a water supply pipe 23 having a water supply valve 22 for supplying washing water, and a drain pipe 25 having a drain valve 24 for draining the washing water. Moreover, the washing tank 1 is accommodated in the slide body 27 which can be taken out from the housing 26. The slide body 27 is provided with a vent hole 28 communicating with the outside.

The operation and action of the dish washing dryer configured as described above will be described below.

First, the user pulls out the slide body 27 from the housing 26, stores the dish to be cleaned in the cleaning tank 1, and returns the slide body 27 to its original state to start cleaning. At the start of the cleaning operation, the water supply valve 22 is opened to feed water from the water supply pipe 23 to the cleaning tank 1, and when a predetermined amount of water is supplied, the water supply valve 22 is closed to stop the water supply. Then, hot water is ejected from the cleaning nozzle 2 by the operation of the cleaning pump 3 serving as the heating section 5 and the cleaning section 4, and is then sprayed on the dish to be cleaned. The washing nozzle 2 is rotated by the reaction force of the washing water jetting, thereby spreading the washing water widely on the object to be cleaned, thereby improving the cleaning property. Although the case where the heating part 5 is operated and wash | cleaned with hot water is shown here, when the dirt of the to-be-washed | cleaned object is weak, it is good to clean it at water supply temperature, without operating the heating part 5. In addition, when the to-be-cleaned object becomes severe, it wash | cleans by adding a detergent. When the washing operation is completed, the drain valve 24 is opened to drain the washing water from the drain pipe 25 to the outside of the housing 26. When the draining is completed, the drain valve 24 is closed.

In the next rinsing operation, no detergent is added, the water is supplied in the same manner as the washing operation, and hot water is ejected from the washing nozzle 2 by the operation of the heating unit 5 and the washing pump 3 to the dish to be cleaned. Spray and circulate. Because of the drying operation of drying the object to be cleaned after the rinsing operation, it is preferable to warm the object to be cleaned in the final rinsing operation, and if the final rinsing operation is performed in hot water of about 60 to 70 ° C., the sterilization treatment is performed. can do. After the rinsing operation is finished, the rinsing water in the washing tank 1 is drained in the same manner as the washing operation is finished.

In the drying operation performed next, the blower unit 6 is driven in order to discharge the air in the washing tank 1 which becomes hot and humid by a rinse operation and to dry the to-be-cleaned object. As a result, the air volume distribution unit 15 distributes and blows the air to the first path 11 and the third path 13, and sends outside air to the mixing unit 14 and the washing tank 1. In particular, the blower section 6 is intermittently operated by the air volume control unit at the start of the drying operation so that the high temperature, high humidity air in the cleaning tank 1 is not directly discharged from the exhaust port 7 after the rinsing operation in the hot water. . In this way, the air volume is reduced and low-pressure external air is applied to the air volume distribution unit 15, and the air is mainly blown to the third path 13 side to cool the exhaust of the high temperature and high humidity discharged at the beginning of the drying stroke, and thereby exhaust port 7 Prevent high temperature, high humidity air from escaping

When the air pressure of the outside air from the blower section 6 is low, the second regulating valve 17 is weighted in the direction of closing the first regulating valve 16, that is, the moment is applied in the clockwise direction in FIG. Since the weight of the first regulating valve 16 is applied, the first regulating valve 16 can be easily maintained in a closed state.

Next, the air volume of the air blower 6 is slightly increased to increase the air pressure of the external air supplied to the air volume distributor 15, and the first control valve 16 is slightly opened to slightly open the first path 11 side. Wind is distributed and blown most of the wind to the third path 13 side. In this way, the mixing section 14 mixes and cools the winds entering the third third path 13 side with respect to the high temperature and high humidity wind pushed out of the washing tank 1 by the wind entering the first path 11 side. The low-temperature wind is discharged from the exhaust port 7.

With the progress of the drying operation, since the humidity of the air exhausted from the cleaning tank 1 decreases due to the inflow of external air into the cleaning tank 1, the temperature of the exhaust gas flowing out of the exhaust port 7 is determined. The external air volume required to cool below the value is at least solved. Therefore, the amount of external air to the mixing section 14 can be reduced as the dry state progresses, and the amount of air to be blown into the cleaning tank 1 is increased by turning the amount toward the first path 11 side to dry the object to be cleaned. It can improve performance. There, the humidity and the temperature decrease due to the supply of the external air into the cleaning tank 1 with the progress of the operation of the blower 6, and the wind pressure of the external air from the blower 6 gradually decreases. Or increase step by step. In connection with this, the opening degree of the 1st control valve 16 becomes large, and the opening degree of the 2nd control valve 17 which rotates in cooperation with the 1st control valve 16 becomes small. Thereby, the air volume ratio of the outside air and the air exhausted from the washing tank 1 is changed, and the air volume ratio toward the first path 11 side is increased to promote the drying.

In addition, when the humidity or temperature in the cleaning tank 1 is lowered and the air in the cleaning tank 1 may be discharged from the exhaust port 7 without cooling, the blowing amount is increased by continuously operating the blower 6. Let's do it. 3, the opening degree of the 1st control valve 16 is made fully open, the 2nd control valve 17 is fully closed, and exhaust from outside air and the washing tank 1 as shown in FIG. The ratio of air volume of air to be used is about 0: 1. That is, the blowing of the blower 6 is made into a drying main body.

In this state in which the first regulating valve 16 is fully open, the second regulating valve 17 is weighted in the direction in which the first regulating valve 16 opens. That is, by putting a moment in the counterclockwise rotation in FIG. 3, the fully open state of the 1st control valve 16 can be easily maintained.

Thus, the opening degree of the 1st control valve 16 and the 2nd control valve 17 changes in conjunction, and the 1st path 11 and the 3rd path | Stable air volume distribution to 13) is achieved. That is, the air volume ratio (air flow amount into the second path 12: air flow amount into the cleaning tank 1) of the outside air and the air exhausted from the cleaning tank 1 can be changed from about 1: 0 to about 0: 1. Can be. Thus, by controlling the opening degree of the 1st control valve 16 and the 2nd control valve 17 using the air blower 6 from cooling to drying, it is possible to realize low power consumption and low cost.

Therefore, low temperature and low humidity of the exhaust gas can be realized by facilitating cooling due to the mixing of the outside air into the air exhausted from the cleaning tank 1 and the change in the air volume distribution, and the humidity rise in the space of the installed room or the like can be reduced. Can improve sex. In addition, by making the air volume distribution variable, both prevention of high-temperature exhaustion and securing of drying performance can be achieved.

In addition, although the 2nd control valve 17 was demonstrated in embodiment about the structure which consists of the main-body part 17a and the bent part 17b of the substantially perpendicular state at the time of stop of the blower part 6, it is not limited to this. It may be made of only the main body portion so as to stop at an angle inclined clockwise than in the substantially vertical state at the time of drying stop. Also in this case, it is possible to apply the moment in the clockwise rotation direction when the wind pressure of the outside air from the blower 6 is lower than the predetermined value, and to apply the moment in the counterclockwise rotation direction when the wind pressure is higher than the predetermined value.

In addition, although the airflow volume distribution part 15 demonstrated the structure provided in the middle of the 1st path | route 11 in embodiment, it is not limited to this, You may provide it in the vicinity of the blower 6.

As is clear from the above, in the dish washing dryer, a washing tank for storing the object to be cleaned, a heating unit for heating the washing water in the washing tank, an exhaust port for discharging air in the washing tank, and supplying external air into the washing tank A first path communicating with the blower, the blower and the cleaning tank, a second path communicating with the exhaust port and the cleaning tank, a third path branching from the first path and connected to the second path, and a first path And a flow rate distribution section provided at the branching section where the third path branches from. The air volume distribution unit has a first control valve and a second control valve in which the opening degree is changed by the wind pressure, respectively in the first path and the third path, and the first control valve and the second control valve are freely rotatable, and the second The control valve is weighted in the direction in which the first control valve is closed in a state where the first control valve is closing the first path. With this configuration, since the first control valve is closed when the air pressure of the external air supplied from the blower is low, such as when the blower unit starts to operate, the external air can be stably supplied to the second path through the third path, The exhaust air can be cooled reliably to reduce moisture and improve drying performance.

In addition, in the case where the second regulating valve has a bent portion provided by bending the distal end of the second regulating valve on the partition wall side between the first path and the third path, it is not necessary to newly overlap and the cost can be realized. In addition, since the second regulating valve can be weighted in the direction in which the first regulating valve opens when the first regulating valve is almost completely open, the distribution of external air can be changed according to the wind pressure.

In addition, in the case where the air volume distribution part forms a part of the first path and the third path, and is detachably provided in the first path and the third path, the first control valve and the second control valve are fixed by the oil or the like and move. Even if a defect occurs in the air volume distribution unit, such as, the maintenance can be easily performed by separating and repairing the air volume distribution unit.

In the case where the projection is provided at the distal end of the blower side of the first regulating valve, the first regulating valve is in point contact with the first path and is not in surface contact with the first regulating valve being closed. This makes it difficult for the first control valve to adhere to the first path.

Moreover, when the rotation axis is provided in the engaging part of a 1st path | route and a 3rd path | route, and the 3rd path | route has a part formed in circular arc shape about the rotation axis, the flow path area of the 3rd path | route in a branch part is Since it can be made constant, the pressure loss of external air can be reduced when the external air from a blower blows from a 1st path to a 3rd path.

Moreover, in the case where the shielding rib which shields the clearance gap of at least one valve of a 1st control valve and a 2nd control valve and a path | route is provided in a path | route, the sealing degree of a control valve and a path | route can be improved in the state which each control valve is closed. Therefore, the amount of external air leaking into the path by the control valve can be reduced, and efficient drying can be realized.

Moreover, the dishwashing dryer which concerns on this invention is useful as a household apparatus which can ensure both the prevention of hot wind feeling by the exhaust which reduced the temperature and humidity discharged at the time of drying operation, and the improvement of drying performance.
