DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a dishwasher for washing dishes. In particular, it relates to a type in which the cleaning tank is of a drawer type.

[0002]

2. Description of the Related Art An example of a drawer-type dishwasher (hereinafter, abbreviated as a dishwasher) according to the related art will be described with reference to FIGS. FIG. 1 is a perspective view showing a state where the cleaning tank is pulled out from the main body of the cleaning machine. FIG. 2 is a schematic longitudinal sectional view showing a state where the cleaning tank is pulled out from the main body of the cleaning machine. FIG. 3 is a schematic longitudinal sectional view showing a state where the cleaning tank is housed in the main body of the cleaning machine. FIG. 4 is a vertical cross-sectional view illustrating details of the wiper blade when the cleaning tank is pulled out of the main body of the cleaning machine. FIG. 5 is a perspective view showing a state where the wiper blade is mounted on the upper portion of the cleaning tank. As shown in FIGS. 1 to 3, the main body 120 is substantially box-shaped and has a front surface (the left side in FIGS. 2 and 3, whereas the right side in the drawing is a rear side). Is open. The cleaning tank 122 has a drawer shape with an open top, and is slidable between a position shown in FIG. 2 pulled out from the main body 120 of the cleaning machine and a stored position shown in FIG. The user of the dishwasher 110 puts the unwashed dishes 13 in the dish basket 132 in the washing tank 122 at the drawer position shown in FIG.
3, and the washing tank 122 is placed in the accommodation position shown in FIG. 3, and the dishwasher 110 is operated to wash the dishes 133. After the operation of the dishwasher 110, the washing tub 122 is pulled out to the draw-out position, and the washed dishes 133 are taken out of the washing tub 122.

[0003] A seal plate 144 is provided so that the washing water 130 does not leak from the washing tank 122 during washing. The seal plate 144 is disposed above the main body 120 of the washing machine. When the washing tank 122 is accommodated in the accommodation position, the seal tank 144 covers the upper open portion of the washing tank 122 and
So that the washing water 130 does not leak out of the device. During operation of the dishwasher 110, the washing water 130 accumulated at the bottom of the washing tank 122 is sucked by the washing pump 124, and the washing water 130 pressurized by the washing pump 124 is discharged from the plurality of nozzle holes 128a of the washing nozzle 128. It gushes vigorously. The tableware 133 stored in the tableware basket 132 is washed by the washing water 130 that spouts vigorously. The washing water 130 which has been jetted to wash the tableware 133 is supplied to the washing tank 12.
Return to the bottom of 2.

The cleaning water 130 is supplied to a plurality of nozzle holes 128a.
The cleaning water 130 adheres to the lower surface of the seal plate 144 as water droplets in order to squirt vigorously. When the dishwasher 110 is performing a normal operation including a drying process, the washing water 130 attached to the lower surface of the seal plate 144 evaporates in the drying process. Will not remain. However, when the operation is temporarily stopped before performing the drying process or when the operation is performed in the operation mode in which the drying process is omitted, the water droplets remain on the lower surface of the seal plate 144 even after the operation is stopped. .

When the cleaning tank 122 is pulled out with water droplets attached to the lower surface of the seal plate 144, the cleaning water 130 falls on the bottom of the box-shaped main body 120 of the cleaning machine. Wash water 13
If a long time elapses while 0 remains on the bottom of the cleaning machine main body 120, corrosion of the cleaning machine main body 120 is caused. Corrosion can be suppressed by manufacturing the washing machine main body 120 with stainless steel or the like having high corrosion resistance, but this increases the product cost. Further, when the cleaning tank 122 is accommodated in a state where the cleaning water 130 is stored at the bottom of the cleaning machine main body 120, the humidity inside the cleaning machine main body 120 increases. Cleaning machine body 1
When the humidity inside the cleaning device 20 becomes high, the components inside the cleaning device main body 120 (for example, the cleaning pump 124) are corroded.

[0006] In order to prevent the washing water 130 from dropping to the bottom of the washing machine main body 120 even when the washing tank 122 is pulled out in a state where water droplets adhere to the lower surface of the seal plate 144, the conventional dishwashing machine 110 is used. Then, a wiper blade 145 is attached along the rear upper edge of the cleaning tank 122 (for example, JP-A-2000-166850). This is shown in detail in FIGS. Wiper blade 1
When the cleaning tank 122 is provided, the wiper blade 145 wipes off water droplets adhering to the lower surface of the seal plate 144 when the cleaning tank 122 is pulled out to the drawing position, and returns the wiped cleaning water 130 into the cleaning tank 122. . That is, in the conventional dishwasher 110, by attaching the wiper blade 145 along the upper edge of the rear portion of the washing tank, water droplets adhering to the lower surface of the seal plate 144 can be removed.
20 was prevented from falling to the bottom. Further, in the above-mentioned publication, a blower is provided in place of the wiper blade 145, and when the cleaning tank 122 is pulled out to the draw-out position, air is blown to the lower surface of the seal plate 144 to blow off the water droplets. Body 120
A technique for preventing falling to the bottom of a car is described.

[0007]

However, the wiper blade 145 is worn and deformed as the sliding of the cleaning tank 122 is repeated. For this reason, if the conventional dishwasher 110 is continuously used, the wiper blade 145 is worn and deformed, and the water droplets adhered to the lower surface of the seal plate 144 cannot be wiped well. In particular, since there are irregularities on the lower surface of the seal plate 144, this problem cannot be ignored. Further, as shown in FIG. 5, the wiper blade 145 is
Since the cleaning tank 122 is mounted along the rear upper edge of the seal plate 144, it is hidden under the front edge of the seal plate 144 as shown in FIG. For this reason, it is difficult to visually check the state of wear and deformation of the wiper blade 145, or to check with a tactile sensation by inserting a hand. If it is difficult to confirm the state of wear and deformation of the wiper blade 145, the user continues to use the dishwasher 110 without noticing the malfunction of the wiper blade 145, and the corrosion of the main body 120 of the washer proceeds. Further, the seal plate 144 interferes with the wiper blade 1
There is also a problem that replacement work of 45 is difficult. Further, when the cleaning tank 122 is pulled out to the draw-out position, in a method in which air is blown to blow off water droplets attached to the lower surface of the seal plate 144, air is blown in a state where the lower surface of the seal plate 144 is opened to the outside. So
Water droplets are easily scattered outside the cleaning tank 122. When the water drops scatter outside the washing tank 122, the water drops fall on the floor where the dishwasher 110 is installed.

An object of the present invention is to provide a dishwasher having high durability and capable of preventing water droplets from splashing out of a washing tank.

[0009]

Means for Solving the Problems, Functions and Effects The dishwasher according to the present invention is drawn out of a box-shaped washer main body having an open front surface, and a storage position housed in the main body. A drawer-type dishwasher having a washing tank slidable between a drawer position and an upper part opened, and a seal plate for covering an upper open part of the washing tank placed in the storage position. An air outlet for blowing air to the lower surface of the seal plate,
Blowing means for feeding air to the air outlet, and control means for activating the blowing means first when the cleaning tank is drawn out before performing the drying step and then switching to a state in which the cleaning tank is allowed to be drawn out are added. Have been. According to the dishwasher of the present invention, when the washing tank is pulled out from the main body of the washing machine in a state where water droplets adhere to the lower surface of the seal plate, the air sent from the blower means is blown out before the pulling out. From the lower surface of the seal plate. The water droplets adhering to the lower surface of the seal plate are blown away and removed by the blown air. Therefore, when the cleaning tank is pulled out, the water drops adhering to the lower surface of the seal plate have already been removed, and the water drops will not fall into the main body of the cleaning machine. In this system, unlike the wiper blade system, no frictional force acts, so that there is no abrasion or deformation in the first place. Therefore, high durability can be obtained. Further, according to the dishwasher of the present invention, in a state where the lower surface of the seal plate is separated from the surroundings by the cleaning tank, the air blows off and removes water droplets attached to the lower surface of the seal plate. As a result, water droplets do not scatter outside the cleaning tank. ADVANTAGE OF THE INVENTION According to the structure of this invention, high durability can be ensured and a water droplet can be prevented from scattering outside the washing tank.

The dishwasher 10 includes a washing machine body 20, a washing tank 22, a seal plate 44, a blower fan 52, a washing tank lock mechanism 72, and the like. As shown in FIGS. 6 and 7, the main body 20 of the cleaning machine has a box shape in which the front surface (the left side in the drawing; the right side in the drawing is the rear side) is opened. Pull-out cleaning tank 22
Is open at the top, and is slidably attached to the washing machine main body 20 via rollers and rails (not shown). A front door 34 is provided on the front side of the cleaning tank 22, and a handle 35 to which a user applies a force is formed here. When the user applies a force to the handle 35, the cleaning tank 22 slides in the horizontal direction between a pull-out position shown in FIG. 6 and a storage position shown in FIG.

As shown in FIGS. 6 and 7, the seal plate 44 is disposed at an upper position in the main body 20 of the washing machine. As shown in FIG. 6, when the cleaning tank 22 is at the drawn-out position, the seal plate 44 holds the upper edge 23 of the cleaning tank.
The position is slightly higher than the position, and does not interfere with the slide movement of the cleaning tank 22. A seal 44 a is mounted on the periphery of the lower surface of the seal plate 44. The cleaning tank 22 and the seal plate 44 are connected by a mechanism (not shown). When the cleaning tank 22 is stored from the drawn-out position to the storage position, the seal plate 44 is lowered in conjunction with the slide of the cleaning tank 22. When the seal plate 44 is lowered, as shown in FIG. 7, the seal 44a is pressed against the upper edge 23 of the cleaning tank, and the upper part of the cleaning tank 22 is covered and sealed. Also, on the lower surface of the seal plate 44,
A water-repellent surface treatment (hydrophobic treatment) is applied so that water droplets are not easily attached and water droplets are easily removed.

A tableware basket 32 is arranged in the washing tank 22, and a tableware 33 is stored in the tableware basket 32. The washing pump 24 communicates with the bottom of the washing tank 22 by a suction passage 27 and communicates with a washing nozzle 28 disposed below the tableware basket 32 by a discharge passage 26. The cleaning nozzle 28 has a plurality of nozzle holes 28a. The cleaning nozzle 28 is rotatable about a joint 29 with the discharge passage 26 as an axis. A water supply passage 46 communicates with a water supply port 22 c formed in the washing tank 22. The drainage pump 25 communicates with the outside of the dishwasher 10 through a drainage passage 48,
Also communicates with. Since the water supply passage 46 and the drainage passage 48 are bendable, the water supply passage 46 and the drainage passage 48 do not hinder sliding between the draw-out position and the storage position of the washing tank 22.

As shown in FIGS. 6 to 9, one end of a blower duct 54 is attached to the washing tank 22 so as to penetrate through the upper portion of the rear wall. As shown in FIG. 9, one end (hereinafter, referred to as an air outlet 54a) of the air duct 54 projecting into the cleaning tank is formed in a nozzle shape whose tip is narrowed. Depending on the shape,
The force of the air blown out from the tip increases. The air outlet 54a is disposed at a position where air is blown to the lower surface of the seal plate 44 when the washing tank 22 is covered with the seal plate 44, and adheres to the lower surface of the seal plate 44 by the blowing of the air. Water drops are blown away. At the other end of the air duct 54, an air duct 54
A blower 52 driven by an electric motor that feeds air to the fan is attached. The front door 34 has the cleaning tank 22.
Exhaust port 34a for discharging air blown into the inside
Are formed. The exhaust port 34a is formed above the front door 34 so that the air blown to the lower surface of the seal plate 44 flows along the lower surface of the seal plate 44 and efficiently blows off water droplets.

The cleaning tank lock mechanism 72 will be described.
As shown in FIG. 6, FIG. 7, and FIG.
2 is swingable around a pin 82a, and a notch 82b is formed at the tip. One end of a spring 83 is attached to the movable cam 82. This spring 83
Is fixed at the other end to the main body 10 of the washing machine (in FIGS. 6 and 7, the spring 83 is omitted for clarity of illustration). The movable cam 82 hits the stopper 85 at the position shown by the dashed line in FIG. 10 and does not rotate any more. A movable cam switch 88 for detecting that the movable cam 82 is at the position indicated by the solid line in FIG. The oscillating plate 87 oscillates around the pin 87 a to rotate the movable cam 82 to a movable cam switch 88.
To the plunger 88a. Movable cam switch 88
When the movable cam 82 is at the position indicated by the solid line in FIG.
The plunger 88a is pushed in through the rocking plate 87 and is electrically turned on. The movable cam switch 88 is "OFF" when the movable cam 82 is at the position indicated by the dashed line in FIG. Electrically actuated solenoid 91
Is attached to the washer body 20. The arm 93 can swing around a pin 93a. The tip of the shaft 91 a extending and contracting from the solenoid 91 is
1b is connected to the arm 93. For this reason,
The arm 93 swings about the pin 93a as the shaft 91a expands and contracts.

A lock position detection switch 95 for detecting that the cleaning tank 22 is locked at the storage position is attached to the main body 20 of the cleaning machine. The shaft 91a of the solenoid 91 contracts when the solenoid 91 is energized. When the shaft 91a contracts, the shaft 9
The arm 93 connected to 1a swings, and the plunger 95a of the lock position detection switch 95 is pushed.
While the plunger 95a is being pressed, the lock position detection switch 95 is electrically turned on. Conversely, when the plunger 95a is not depressed, the lock position detection switch is turned off. On the rear side of the washing tank 22, a plate 94 is mounted in a horizontal direction, and a pin 94a is formed on the plate 94. The operation sequence (operation sequence) of the blower fan 52, the cleaning tank lock mechanism 72, and the like is controlled by an electric control circuit (not shown).

Next, the operation of the dishwasher 10 will be described. When the cleaning tank 22 is at the draw position shown in FIG.
The seal plate 44 is moving upward. Cleaning tank 22
The user puts the tableware 33 into and out of the tableware basket 32 in the washing tank 22 in a state where is in the drawer position. The user
When the cleaning tank 22 is pushed toward the main body 20 of the cleaning machine, FIG.
At the storage position, the seal 44a of the seal plate 44 is pressed against the upper edge 23 of the cleaning tank. When the seal 44a is pressed against the upper edge 23 of the cleaning tank, the cleaning tank 22 is covered, and the cleaning water 30 is removed.
Does not leak out of the cleaning tank 22.

Further, the cleaning tank lock mechanism 72 operates simultaneously with the movement of the seal plate 44, and this will also be described. When the cleaning tank 22 is pushed into the housing position, the pins 94a formed on the plate 94 of the cleaning tank 22 enter the notches 82b of the movable cam 82. When the cleaning tank 22 is further pushed in, the movable cam 82 rotates clockwise (FIGS. 6 and 7; the same applies hereinafter).
, And the spring 83 is stretched. During the rotation of the movable cam 82, the direction of the force applied by the spring 83 to the movable cam 82 changes. That is, during the rotation of the movable cam 82, a force was previously applied in the counterclockwise direction, but thereafter, the force is applied in the clockwise direction. When the movable cam 82 further rotates, the movable cam 82 pushes the plunger 88a of the movable cam switch 88 through the rocking plate 87, and is stabilized at this position (the position shown by the solid line in FIG. 10) while being pulled by the spring 83. I do. Pin 9 of cleaning tank 22
The cleaning tank 4a is held at this storage position because the cleaning tank 4a has entered the notch 82b of the movable cam 82.

After pushing the washing tub 22 to the storage position, the user turns on the operation switch (not shown) of the dishwasher 10. As described above, in this state, the plunger 88a is pushed in, and the movable cam switch 88 is turned on. On condition that both the operation switch and the movable cam switch 88 are "ON", the electric control circuit energizes the solenoid 91 and the shaft 91a contracts. When the shaft 91a contracts, the arm 93 swings around the pin 93a, and the tip 93b of the arm 93 moves to a position (lock position) for restricting the movement of the movable cam 82 as shown in FIG.
In this state, even if the user tries to pull out the cleaning tank 22 by applying force to the handle 35, the pins 94a of the cleaning tank 22
Is restricted by the notch 82b of the locked movable cam 82, so that the cleaning tank 22 cannot be pulled out. Further, the plunger 95a of the lock position detection switch 95 for detecting that the cleaning tank 22 is locked is pushed into the arm 93 and turned on. The operation of the dishwasher 10 is started on condition that the lock position detection switch 95 is turned on. As described above, when the cleaning tank 22 is in the storage position, the cleaning tank 2
2 is covered by a seal plate 44, and the dishwasher 10 cannot be operated unless the washing tank 22 is locked at the storage position. That is, the dishwasher 10 is operated in a state where the washing tank 22 is drawn out and the washing tank 22 is not covered, and the washing water 30 does not leak to the outside.

When the cleaning operation is started, the cleaning water 30 is supplied from the water supply passage 46 to the water supply port 22c of the cleaning tank 22.
As shown in FIG. 7, cleaning water 30 is stored at the bottom of the cleaning tank 22. Next, the cleaning pump 24 starts operating, and the cleaning water 30 at the bottom of the cleaning tank 22 is sucked into the cleaning pump 24 through the suction passage 27 and pressurized. The pressurized washing water 30 is supplied to the washing nozzle 28 through the discharge passage 26 and spouts vigorously from the nozzle hole 28a to wash the tableware 33 stored in the tableware basket 32. The cleaning nozzle 28 is connected to the discharge passage 26 at the joint 2 with the discharge passage 26 due to a counter operation in which the cleaning water 30 is ejected from the nozzle hole 28a.
Rotating around the axis 9, the washing water 30 is sprayed at various angles on the tableware 33. The washing water 30 that has washed the dishes 33 returns to the bottom of the washing tank 22 again. Wash water 30
By repeating the above operation, the tableware 33 is washed. When the cleaning water 30 is discharged from the cleaning tank 22, the drainage pump 25 operates to draw the cleaning water 30 from the bottom of the cleaning tank 22 via the suction passage 27. Wash water 3 sucked from washing tank 22 by drain pump 25
0 is discharged to the outside of the dishwasher 10 through the drain passage 48.

The washing water 30 gushes vigorously from the nozzle hole 28 a of the washing nozzle 28 reaches the upper portion of the washing tank 22 and adheres to the lower surface of the seal plate 44. Water drops of the washing water 30 adhered to the lower surface of the seal plate 44 evaporate in the drying process in the normal operation of the dishwasher 10 including the drying process, and thus do not remain as water droplets on the lower surface of the seal plate 44 after the operation is stopped. . However, if the operation is suspended before performing the drying process (it is often done to forget to store the dishes and add more dishes)
Alternatively, when the operation is performed in the operation mode in which the drying step is omitted (operation time saving mode), water droplets remain on the lower surface of the seal plate 44 after the operation is stopped.

When the dishwashing operation is stopped under the above-described operating condition in which water drops remain on the lower surface of the seal plate 44, the electric control circuit keeps energizing the solenoid 91. When the energization of the solenoid 91 is continued, the shaft 91a remains contracted, the distal end 93b of the arm 93 is at a position (lock position) for restricting the movement of the movable cam 82, and the user needs to clean the cleaning tank 22. Can't withdraw. That is, the cleaning tank 22 cannot be pulled out in a state where water droplets adhere to the lower surface of the seal plate 44. Next, the blower fan 52 operates to send the sucked air into the blower duct 54, and the blown air is blown from the air outlet 54 a of the blower duct 54 onto the lower surface of the seal plate 44 vigorously. The vigorously blown air causes the seal plate 44
The water droplets adhering to the lower surface of the are blown off and removed. Since the lower surface of the seal plate 44 has been subjected to a hydrophobic treatment for repelling water, the attached water droplets are easily blown off. In this state, since the cleaning tank 22 is covered with the seal plate 44, the blown water droplets do not scatter outside the cleaning tank. The blown water drops fall to the bottom of the cleaning tank 22. Blower fan 52
Stops when the water droplets adhering to the lower surface of the seal plate 44 are operated for a certain period of time enough to be blown off and removed. Subsequently, the power supply to the solenoid 91 is stopped, and the shaft 91a extends. When the shaft 91a extends, the arm 93 swings around the pin 93a,
The distal end 93b of the arm 93 deviates from a position (lock position) that restricts the movement of the movable cam 82. Tip 9 of arm 93
When 3b deviates from the locked position, the movable cam 82 becomes rotatable, and the user can pull out the cleaning tank 22. Even if the cleaning tank 22 is pulled out in this state, since the water droplets adhering to the lower surface of the seal plate 44 have been removed, the water droplets fall on the bottom of the main body 20 of the cleaning machine, and the corrosion of the main body 20 of the cleaning machine 20 occurs. Does not occur.

As described above, the dishwasher according to the embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment at all, and the present invention can be variously modified based on the knowledge of those skilled in the art. It can be implemented in an improved form. For example, the air outlet 54a that blows out the air illustrated in FIG. 8 has a horizontally long shape, but may have a shape in which a plurality of holes are horizontally connected. Further, the shape of the lower surface of the seal plate is not necessarily flat, and there is a portion to which water droplets easily adhere. The shape of the air outlet may be formed so that the air can be blown in a concentrated manner on the portion where the water droplets easily adhere. When there are a plurality of portions to which water droplets easily adhere, the air outlet may be branched to provide a plurality of air outlets. In addition, the air outlet does not necessarily need to be blown from the rear of the washing tank toward the front. You may blow out from the side of a washing tank toward the opposite side. The air may be blown from below the seal plate toward the lower surface of the seal plate. An air outlet may be attached to the seal plate. In addition, the dishwasher
Since it usually has a blower fan for supplying air for drying dishes into the washing tank, the blower fan for drying dishes and the blower fan according to the present invention that blows off water droplets attached to the lower surface of the seal plate are provided. They can be shared.

Further, the blowing means may be constituted by a high-pressure vessel and an on-off valve. By opening the on-off valve and instantaneously blowing the high-pressure air stored in the high-pressure container from the air outlet, water droplets on the lower surface of the seal plate can be blown off. Further, the high-pressure air stored in the high-pressure container may be generated by operating a compressor for compressing the air while the dishwasher is operating. According to this configuration, there is no need to supply high-pressure air to the high-pressure container from outside the dishwasher. Further, the blowing may not be stopped after continuing for a certain period of time, but may be stopped after detecting that water droplets on the lower surface of the seal plate have been blown off (removed) by an optical method or the like. Further, a display device for notifying the user that the blowing means is operating may be provided on a front door or the like. If the user knows that the blower is operating and does not pull out the washing tank, the washing tank lock mechanism is not necessarily required.
