Further, when the washing is completed, the washing water in the retaining portion is discharged from the drain port, so that the float is lowered, the lock of the locking member is released, and the door can be opened.
[0013]
Further, as a third means for solving the above-mentioned problem, in the present invention, a locking member interlocking with the operation member is provided on the door, and the locking member is disengaged from a part of the dishwasher main body. In a door lock device for a dishwasher, a lock member that engages with the lock member, a lock spring that urges the lock member in a lock direction, and an electromagnetic member that moves the lock member in a lock release direction in opposition to the lock spring. A solenoid is provided on each of the main bodies, and a stagnant portion of the washing water scattered and flowing down on the inner surface of the door is provided on the inner surface of the door, and the bottom of the stagnant portion has an outflow amount smaller than the inflow amount of the washing water. A drain is provided, a float is accommodated in the staying portion, and a detecting means interlocked with the float is provided, and the electromagnetic solenoid is controlled based on an electric signal of the detecting means.
[0014]
In this case, when the cleaning is started by closing the door, when the washing water scattered on the inner surface of the door flows down and accumulates in the stagnant portion, the float floats up and the detecting means is activated. When the electromagnetic solenoid is turned on by the ON signal of the detection means, the lock member is operated and engages with the locking member to lock it. Therefore, the lock is not released even if the operation member is shaken during the washing, and the door is not opened. Also, when the washing is completed, the washing water in the stagnant portion is discharged from the drain port, so that the float is lowered and the signal of the detecting means is turned off, whereby the electromagnetic solenoid is turned off, the lock is released, and the door can be opened. Become.

[0027]
The projection 24 at the lower end of the upper locking member 15 is fitted into the right guide groove 25 of the operating member 17, and the projection 26 of the lower locking member 16 is fitted into the left guide groove 27. The actuating member 17 is slidable in a horizontal direction at a constant stroke S (see FIGS. 8 and 9B), and at the rear end of the stroke, the horizontal portion 34 contacts the rear end of the horizontal guide groove 46 and is regulated. (See FIG. 9A).
[0028]
In a normal state where the operation button 8 ′ is not operated, the projection 31 abuts near the tip of the inclined cam surface 37. At this time, the operating member 17 is at the rear end of the stroke, the projection 24 of the upper locking member 15 is located at the upper end of the right guide groove 25 (see FIG. 6), and the projection 26 of the lower locking member 16 is 27 is located at the lower end.

As described above, the moving direction in which the operating member 17 starts moving from the state shown in FIGS. 6 and 9A at the rear end of the stroke and reaches the front end of the stroke shown in FIGS. 8 and 9B. Is referred to as a “lock release direction” in this specification, and the opposite movement direction is referred to as a “lock direction”.
[0031]
Next, the structure of the float device 59 will be described (see FIGS. 6, 8, and 12). The float device 59 faces the inside of the main body 1 and is a surface exposed to the splash of washing water during dishwashing. The float device 59 is provided with the above-mentioned wall surface 42 for collecting the washing water flowing down along the surface. A guide portion 61 is provided with a part inclined, a rib-shaped guide portion 61 'is provided to face the guide portion 61, and a water collecting notch 62 (see FIG. 12) is provided at the lower end thereof. . A stagnant portion 63 having an open upper end is provided below the notch 62 for collecting water, and the float 19 is stored in the stagnant portion 63. One side surface of the stagnation portion 63 is formed by the lower end portion of the wall surface 42, and the other two side surfaces are overflow walls 64, 64 'having a constant height. A slit-shaped drain port 65 is provided at the lower end of one overflow wall 64. The drain port 65 is formed so as to have an outflow amount smaller than the inflow amount of the cleaning water flowing into the stagnant portion 63 within a certain period of time, and a state in which the water constantly overflows from the overflow walls 64 and 64 ′ during the cleaning, ie, The retaining section 63 is set so as to be always full. If the washing is stopped, the inflow of the washing water stops, so that when the inside water flows out from the drain port 65, the inside becomes empty.
[0032]
The float 19 has a box shape with an open lower surface, and a support arm 66 is provided on a wall surface opposite to the wall surface 42, that is, a wall surface on the overflow wall 64 'side. The support arm 66 is supported by a support shaft 67 at a portion over the overflow wall 64 so as to be vertically swingable. The float 19 can be moved up and down by the swing of the support arm 66, and the movement in the horizontal direction is regulated by the support arm 66.
[0033]
When the float 19 is simply stored movably in the up-down direction without providing the support arm 66, the wall surface of the stagnant portion 63 is made to approach the float 19 so as to restrict the movement in the horizontal direction.
[0034]
The above-described opening 47 is provided in the wall surface 42 that forms one wall surface of the stay portion 63 (see FIGS. 8 and 12), and the packing 18 is inserted into the opening 47. The positional relationship between the part 51 and the float 19 is such that when the float 19 floats inside the stagnant part 63 with full water (see a two-dot chain line in FIG. 6), the float 19 comes into contact with the front end face of the head part 51, and When the water in the part 63 is drained and the float 19 descends, as shown in FIG. 9, the head 51 below the head 51 and advanced in the unlocking direction should not interfere with the float 19. Positioned.
[0035]
The dishwasher according to the embodiment is as described above, and the operation thereof will be described next. As shown in FIG. 1, when the operation buttons 8, 8 ′ are not operated with the doors 2, 2 ′ closed, the protrusion 31 of the operation button 8 ′ is positioned at the tip of the inclined cam surface 37 of the operating member 17. The operating member 17 is at the rear end of the stroke because it is in contact with or close to the part (see FIG. 9A). Therefore, as described above, the upper locking member 15 and the lower locking member 16 are respectively fitted into the locking recesses 22 and 22 ′ of the main body 1, and the doors 2 and 2 ′ are locked to the main body 1. . When the operation buttons 8 and 8 'are pressed in this state, the operating member 17 advances in the unlocking direction, and the upper locking member 15 and the lower locking member 16 are locked by the action of the left and right guide grooves 25 and 27. The lock is released by getting out of the recesses 22, 22 '. The release of the lock allows the doors 2, 2 'to be opened.
[0036]
Next, when the doors 2 and 2 'are closed, the doors 2 and 2' are locked to the main body 1 by the reverse operation. When the cleaning is started, the cleaning water is scattered inside the main body 1, and a part of the water scatters on the inner surfaces of the doors 2 and 2 '(that is, the inner surface of the back plate 13 on the main body 1 side). The splashed washing water is collected by the guide portions 61 and 61 ′ (see FIG. 12), and falls from the water collecting notch 62 to the staying portion 63 thereunder. A part of the washing water in the stagnant portion 63 flows out from the drain port 65. However, since the flush water equal to or more than the amount of the effluent flows into the stagnant portion 63, the float 19 retains the air therein and floats, and overflows. In this state, it becomes the highest position and comes into contact with the front end face of the head portion 51 of the packing 18 (see the two-dot chain line in FIG. 6). Since the movement of the float 19 in the horizontal direction is restricted by the support arm 66, the packing 18 and the operating member 17 integral therewith are prevented from advancing in the unlocking direction, and the operation button 8 or 8 ' It cannot be pushed in, and the doors 2, 2 'are locked. This state continues as long as the washing water is scattered during the washing.
[0037]
When the washing is completed, the washing water is not scattered. Therefore, the washing water in the retaining portion 63 is discharged from the drain port 65, becomes empty, the float 19 descends, and the lock is released. Therefore, when the user pushes the operation button 8 or 8 ', the convex portion 31 pushes the inclined cam surface 37 to advance the operating member 17 in the unlocking direction, and when reaching the front end of the stroke, the upper locking member 15. The lower locking member 16 escapes from the locking recesses 22, 22 ', respectively. As a result, the locking of the doors 2 and 2 'to the main body 1 is released, so that the doors 2 and 2' are bent into a V-shape by the spring force of the central hinge portion 3, and the two doors 2 and 2 'are in a fully opened state where they overlap.
[0038]
When closing the doors 2 and 2 ′ in the fully opened state, the left and right handles 7 and 7 ′ are gripped and pulled back against the spring force of the center hinge portion 3 so that the upper end of the upper locking member 15 is locked. When the coil spring 23 matches the concave portion 22, it rises by the spring force of the coil spring 23, and its upper end is fitted into the locking concave portion 22. Since the projection 24 also rises with the rise of the upper locking member 15, the force acts on the wall surface of the right guide groove 25, and the operating member 17 is retracted (moved in the locking direction). When the operating member 17 is retracted, a downward force is applied to the projection 26 fitted in the left guide groove 27, and the lower locking member 16 is lowered, and its lower end is fitted into the locking recess 22 '. Thereby, the doors 2 and 2 ′ are closed and locked to the main body 1.
[0039]
Next, another embodiment will be described with reference to FIGS. A description will be given mainly of a portion different from the above case. First, in the case of this embodiment, a notch recess 68 is provided at the upper end of the upper locking member 15 (see FIG. 14), and the claw 70 of the lock member 69 provided on the main body 1 is engaged with and disengaged from the notch recess 68. I try to make it. The lock member 69 is inserted into the inside of the main body 1 from above the upper end of the locking recess 22, and is mounted so as to be swingable in the middle by a swing pin 71. A coil spring 72 is pressed against the end protruding upward from the swing pin 71, and the lower claw 70 is always engaged with the notch recess 68 to urge the upper locking member 15 in the locking direction. Have been.
[0040]
An electromagnetic solenoid 73 is provided on the opposite side of the coil spring 72 across the upper end of the lock member 69. The plunger 74 of the electromagnetic solenoid 73 is urged in the protruding direction by a spring (not shown) housed therein, and overcomes the spring force of the coil spring 72 to cut out the claw 70 of the lock member 69 and cut out the recess 68. And release the lock. When the electromagnetic solenoid 73 is energized and turned on, the plunger 74 retreats, the locking member 69 is actuated by the spring force of the coil spring 72, and the claw 70 engages with the notch recess 68 to lock.
[0041]
In order to send a lock signal to the electromagnetic solenoid 73, as shown in FIG. 13, a stagnant portion 63, a float 75, and a microswitch 76 as a detecting means activated by the float 75 are provided in the float device 59. Can be As in the case described above, the stay portion 63 is provided below the water collecting notch 62 at the lower end of the guide portions 61 and 61 '. A drain port 65 is provided at the lower end of the stagnation section 63, and an overflow port 77 is provided at a position at a certain level.
[0042]
A float chamber 78 is provided in communication with a part of the stagnation section 63, and the float 75 is stored in the float chamber 78. A rod 79 provided upward at the upper end of the float 75 protrudes out of the float chamber 78 and faces the armature 81 of the microswitch 76 mounted outside. When the flush water reaches the level of the overflow port 77, the rod 79 of the float 75 comes into contact with the armature 81 and outputs an ON signal from the micro switch 76 to a control unit (not shown). The control unit turns on the electromagnetic solenoid 73 based on the signal to perform the locking operation.
[0043]
The structure of the lock device 14 is basically the same as that described above, except that the opening 47 is not provided in the wall surface 42, and therefore, the rod portion 39 of the operating member 17 penetrates the wall surface 42. And no packing 18 is required. That is, in this case, there is no idea that the operation of the operating member 17 is locked by restricting the operation of the operating member 17 with the float 75 as described above, and the locking is performed by the electromagnetic solenoid 73, and a signal for operating the electromagnetic solenoid 73 is transmitted to the floating portion 63. The output is made by the operation of the micro switch 75 and the micro switch 76.
[0044]
【The invention's effect】
As described above, according to the present invention, a part of the cleaning water generated by the start of cleaning is retained, and when it is detected by the float that the retention level has reached a certain level or more, it is determined that the cleaning is being performed, and the surface is raised.
