Description

Dishwasher {DISHWASHER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dish washer that sprays washing water to perform washing of dishes and the like.

12 is a perspective view of a main portion showing the structure of a conventional dish washing machine. In such a dish washing machine, to-be-cleaned objects, such as tableware, are accommodated in a washing tank (not shown). The opening 101 is provided in the washing tank. The user closes the opening 101 to the upper door 102 and the lower door 103 and then drives a cleaning pump (not shown). The washing water is then sprayed from the nozzle (not shown) to clean and rinse the object to be cleaned.

The upper door support member 104 moves the upper door 102 to the upper space of the main body 105 to open the opening 101. In addition, the lower door support member 106 and the upper door support member 104 are connected by an interlocking member 107. When the lower door 103 is opened and closed, the upper door 102 is also opened and closed in conjunction with this. Therefore, the entire opening 101 is opened and closed by the opening and closing operation of the lower door 103. In addition, the locking mechanism (not shown) keeps the upper door 102 and the lower door 103 in a fully closed state.

The cleaning pump stops automatically when the cleaning and hemging ends. In addition, the operation of the washing pump is stopped when the user presses the pause button even during washing or hemging. However, if the user releases the lock mechanism without pressing the pause button, the upper door 102 and the lower door 103 are opened while the cleaning pump is operated to open the opening 101. Therefore, there exists a possibility that wash water may jump out of a washing machine.

That is, the upper door 102 and the lower door 103 operate simultaneously with the user pressing the push button switch for releasing the lock mechanism, so that the opening 101 is greatly opened. Even if the operation of the cleaning pump is stopped at the same time as the lock mechanism is released, the cleaning water is sprayed for a certain time by the inertia of the cleaning pump and does not stop for a while. Therefore, the washing water splashes out of the washing machine from the opening 101 that is opened.

On the other hand, the structure which provides the safety switch which interlocked with the lock mechanism, and does not operate a cleaning pump in the state which a door is not closed is proposed. In this configuration, when the door lock mechanism is released during the operation of the cleaning pump, the operation of the cleaning pump is immediately stopped. In addition, a mechanism has been proposed in which the door is locked in a closed state during operation. However, when additional dishes are added after the start of operation, operation of the operation stop is required at that time, which is inconvenient to use. Since the lock of the door is also released by the operation of the operation stop, even if the operation of the cleaning pump is stopped at the same time as the operation of the operation stop, splashing of the cleaning water by the inertia of the cleaning pump does not solve.

The present invention is a dish washing machine which prevents the washing water from splashing out of the washing machine from the opening even when the lock mechanism of the door is released during the washing pump operation. The dishwasher of this invention has a washing tank, a washing pump, a door, a lock mechanism, a lock release operation part, a switch, and an opening / closing mechanism. The cleaning tank accommodates the object to be cleaned. The washing pump pressurizes the washing water and sprays the washing water. The door opens and closes the opening of the cleaning tank, and is composed of an upper door and a lower door divided up and down. In the fully closed state, the lower end of the upper door is provided to face the upper end of the lower door. The lock mechanism keeps the door completely closed. The lock release operation unit performs a release operation of the lock mechanism. The switch is provided to stop the operation of the cleaning pump during the release operation of the lock mechanism. The opening / closing mechanism presses the upper door in the fully closed direction until the lower door is displaced in the opening direction of the lower door to a position where the upper end of the lower door is exposed from the lower end of the upper door during the release operation of the lock mechanism. According to this configuration, even when the lock mechanism is released during the operation of the cleaning pump, the washing water can be prevented from splashing out of the washing machine.

Moreover, the 1st holding part 36 is provided in the upper door pulling-in member 30. As shown in FIG. On the other hand, the second holding part 37 is provided in the side wall of the washing tank 2. The first holding part 36 and the second holding part 37 are connected by a first spring 38 composed of a tension coil spring. By this configuration, the upper door 6 and the lower door 7 are opened in a predetermined amount from a completely closed state, until the contact between the upper door inlet pin 33 and the upper door inlet protrusion 34 is released. The door retracting member 30 presses the upper door supporting member 14 in the direction in which the upper door 6 closes.

Moreover, the 3rd holding part 39 is provided in the upper door support member 14, and the 4th holding part 40 is provided in the side wall of the washing tank 2. As shown in FIG. The third holding portion 39 and the fourth holding portion 40 are connected by a second spring 41 composed of a tension coil spring. By this configuration, the upper door 6 is elastically pressed in the closing direction.

Moreover, the 5th holding part 42 is provided in the interlocking member 24, and the 6th holding part 43 is provided in the side wall of the washing tank 2. As shown in FIG. The fifth holder 42 and the sixth holder 43 are connected by a third spring 44 composed of a tension coil spring. With this configuration, the interlocking member 24 in the direction in which the upper door 6 and the lower door 7 open in the middle of the opening from the fully closed state (the lower door 7 rotates about 45 ° from the fully closed state). ) Is elastically pressed. Further, the interlocking member 24 is elastically pressed in the direction in which the upper door 6 and the lower door 7 are closed from the middle of the opening to the fully open state.

6, the manual operation part 25 is provided in the upper end of the lower door 7. As shown in FIG. When the user opens and closes the lower door 7, the upper door 6 is also opened and closed in conjunction with the operation of the lower door 7. In addition, the manual operation unit 25 is covered by the lower end of the upper door 6 in the fully closed state.

The operation and action of the dish washing machine in the embodiment of the present invention configured as described above will be described. When the door is completely opened, the user presses the push button switch 19 to execute the release operation of the lock mechanism 21. Then, the locking mechanism 21 is released from the locking portion 20 so that the interlocking member 24 pressed by the third spring 44 operates in the opening direction of the upper door 6 and the lower door 7. do. That is, as shown in FIG. 6, the lower door 7 is rotated by a predetermined amount in the direction of the arrow A to be displaced. At this time, when the washing pump 46 is in operation, since the switch 48 which cooperates with the lock mechanism 21 is OFF, the operation of the washing pump 46 is stopped.

The upper door 6 is pressed in the completely closed direction until the manual operation unit 25 provided at the upper end of the lower door 7 is displaced from the position covered by the lower end of the upper door 6 to the exposed position. That is, the upper door 6 is completely closed by the pressing force of the second spring 41 to the upper door support member 14 and the upper door inlet input of the upper door inlet member 30 to the upper door support member 14. Direction, and is maintained near the fully closed position. In this way, only the lower door 7 is opened at the beginning of the opening. On the other hand, the upper door 6 stays in the fully closed position, and becomes the state of FIG. 6 from the state of FIG. Therefore, even when the lock mechanism 21 is released during the operation of the washing pump 46, the washing water can be prevented from splashing out of the washing machine.

By opening the lower door 7 in a direction in the direction of the arrow A, the manual operation unit 25 covered by the lower end of the upper door 6 is exposed. Therefore, after the user executes the release operation of the lock mechanism 21, the user until a certain time until the lower door 7 is opened by a certain amount, that is, the displacement from the state of FIG. 1 to the state of FIG. 6. Cannot touch the manual operation unit 25. That is, after operating the push button switch 19, the manual operation part 25 which opens the lower door 7 is exposed, and it becomes possible to operate manually. Therefore, the user cannot open the lower door 7 while the cleaning pump 46 is operating inertia. Thus, the inertial operation of the cleaning pump 46 can prevent the washing water from splashing out of the washing machine.

As described above, the receiving part 6b is provided at the lower end of the upper door 6 (FIG. 10), and the sealing part 9 between the doors is provided at the receiving part 6b. The intersealing sealing packing 9 is located at the upper end of the lower door 7, and the lower and lower doors of the upper door 6, together with the first pressing part 7c overlapping each other on the front side of the receiving part 6b. The sealing part between the upper ends of (7) is comprised. The door-to-door sealing packing 9 seal-tightly couples the receiving part 6b and the 1st press part 7c. By this configuration, the time can be provided until the lower door 7 is displaced by a predetermined amount after the lock is released and the manual operation unit 25 is exposed from the lower end of the upper door 6. Therefore, the user cannot open the door while the cleaning pump 46 is operating inertia. Therefore, the inertial operation of the washing pump 46 can prevent the washing water from splashing out of the washing machine.

Further, the lower end of the intersealing sealing packing 9 is provided with a protruding piece 9a extending downward, and the lower door 7 has a second pressing part 7d for urging the protruding piece 9a when it is completely closed. ) Is provided. When the lower door 7 is displaced from the fully closed position of FIG. 10 to the position shown in FIG. 11 where the manual operation unit 25 is exposed, the projecting piece 9a is pressed by the pressing force of the second pressing portion 7d. ) To the side. Therefore, the protruding piece 9a covers the gap formed between the lower door 7 and the upper door 6. Furthermore, the protruding piece 9a acts to further close the gap between the doors when the washing water touches. As a result, it is possible to reliably prevent the washing water from splashing out.

In addition, as mentioned above, in this embodiment, it is comprised so that the upper door 6 may remain in a fully closed position by the two mechanisms of the 2nd spring 41 and the upper door retracting member 30 at the initial stage of opening. However, depending on the weight of the upper door 6 or the constraints of the space in which the second spring 41 or the upper door retracting member 30 is to be inserted, the upper door 6 is completely closed by only one mechanism. It is also possible to set it as the structure which stays in a position.

Next, as shown in FIG. 8B, when the connecting shaft 23a completely moves the clearance region in the elongated hole 23b, the connecting shaft 23a and the elongated hole 23b are connected to each other, and the upper door 6 And the lower door 7 operate in conjunction.

In combination with the opening operation of the upper door 6 and the lower door 7, the upper door drawing member 30 moves upward. When the upper door 6 and the lower door 7 are opened by a predetermined amount, the second rail shortcoming 32a of the second guide rail 32 and the second guide pin 29 are in contact with each other, as shown in FIG. 2. do. In addition, when the upper door 6 and the lower door 7 are opened, the upper door retracting member 30 has the second guide pin 29 as a point, so that the first guide disadvantage of the first guide rail 31 ( It rotates until 31a) and the 1st guide pin 28 contact.

As the upper door inlet member 30 rotates, the contact between the upper door inlet pin 33 and the upper door inlet protrusion 34 is released, so that the upper door inlet member 30 is connected to the upper door 6 and the lower door. (7) is not pressed in the closing direction. The upper door retracting member 30 is pressed downward by the first spring 38, but does not move downward because the first guide pin 28 protrudes and extends to the upper surface of the first guide rail 31. 2, it stays in an upward position as shown in FIG.

In this way, the upper door retracting member 30 is fully retracted from the vicinity of the door full closure where the upper door 6 receives the repulsive force from the sealing member 8 and a large closing force is required to completely close the upper door 6 to the normal position. Only apply the door closing force over the closing. Therefore, it is possible to effectively close the upper door 6 to the normal fully closed position, as compared with the configuration in which the pressing force in the fully closed direction always acts like the second spring 41.

In addition, when the door is completely closed, the upper door inlet pin 33 is in contact with the upper door inlet triggering unit 35, and the upper door inlet protrusion 34 and the upper door inlet tree are rotated while the upper door inlet member 30 is rotated. It slides between the rejects 35. Hereinafter, the state of FIG. 1 is returned to the above in reverse order.

In addition, the upper door 6 and the lower door 7 contact the upper door support member 14 to the first stop 15 and the lower door support member 17 to the second stop 18, respectively. Open until fully open. At this time, the upper door 6 and the lower door 7 are substantially horizontally upward at both sides thereof, and the upper door 6 is completely opened so that the upper door 6 is positioned above the lower door 7 and overlaps each other. Therefore, the upper door 6 is not covered in the upper part of the opening part 5 conventionally. Therefore, the washing | cleaning water adhering to the washing tank 2 side of the upper door 6 is not dripped in the fully open state.

In addition, the manual operation part 25 is provided in the upper end of the lower door 7. Therefore, unlike the case provided in the front surface of a door, the manual operation part 25 does not contact with the surface in which a dishwasher, such as a sink, was installed in the door fully open state.

After the upper door 6 and the lower door 7 are completely opened, the user pulls out the dish basket 4 over the inner surface of the upper door 6 to set the object to be cleaned 3. Since the dish basket 4 is pulled out on the inner surface of the upper door 6, it is possible to prevent the station and water droplets falling from the object to be cleaned 3 to flow out of the washing machine. Moreover, when setting the to-be-cleaned object 3, the water droplet which falls from the to-be-cleaned object 3, and adhered to the outer side rather than the upper door sealing part 6a, collects in the drip part 11. FIG.

Moreover, since the upper door 6 opens downward from the opening part 5 and moves below the dish basket 4, the upper part of the opening part 5 is not covered with the upper door 6. As shown in FIG. Therefore, the user can easily set the object to be cleaned 3 and can use the upper surface of the main body 1 as a space for placing an object. Moreover, since the open space for moving the upper door 6 is not needed above the main body 1, it is easy to install even in a narrow kitchen.

Subsequently, the user stores the dish basket 4 in the washing tank 2 and closes the lower door 7. Since the upper door 6 and the lower door 7 are configured to open and close in conjunction, the upper door 6 is also closed at the same time. By the second spring 41, the pressing force in the closing direction acts on the upper door 6 via the upper door supporting member 14. In addition, the pressing force in the closing direction acts on the interlocking member 24 by the third spring 44. For this reason, the user can close the lower door 7 with a small force.

The water accumulated in the drip tray 11 of the upper door 6 in the fully opened state, as shown in Fig. 5, the outlet drips 12 on the opening 5 side of the drip tray 11 at the time of rotation until complete closure. ), It flows downward and is recovered to the drip tray 10 of the lower door 7 via the outlet 12. As described above, since the upper door 6 and the lower door 7 open and close interlockedly, the outlet 12 of the upper door 6 and the drip tray 10 of the lower door 7 remain in close proximity. This can improve the recoverability of water. Moreover, by receiving the water which flows out from the outflow part 12 in the inclined state in which the drip tray part 10 has an angle from a horizontal plane, the scattering of the water droplet at the time of receiving water can be suppressed.
