The storage space is configured to be slidable in the storage movement direction indicated by arrow A and in the drawer movement direction indicated by arrow B. In addition, the washing tank 2 is configured to be able to be drawn out in a state in which most of the washing tank 2 is exposed to the outside of the washing machine body 1.

  In other words, the drawer-type dishwasher S stores the cleaning object such as dishes in the washing tank 2 in the drawer state in which the washing tank 2 is pulled out from the washing machine body 1, and the washing tank 2 is stored in the washing machine body. The upper opening 4 of the cleaning tank 2 is closed by the inner lid 10 in the storage state stored in the storage position 1, and a cleaning operation for cleaning the dishes 5 is performed.

  Below the cleaning tank 2, devices such as a cleaning pump are arranged in a state assembled to the cleaning tank 2. Inside the cleaning tank 2, a cleaning nozzle and a heater for heating are arranged. In addition, a cleaning basket for storing an object to be cleaned such as tableware is removably stored inside the cleaning tank 2, but since the configuration thereof is well known, the description thereof is omitted. .

As shown in FIG. 1, a rectangular plate-like door body 9 that closes the cleaning tank insertion / removal opening 3 of the cleaning machine body 1 is provided at the front portion of the cleaning tank 2 in the storage state of the cleaning tank 2. .
Specifically, the door body 9 is configured such that its lateral width is slightly larger than the lateral width of the cleaning machine body 1 and its vertical width is the same as the vertical width of the cleaning machine body 1.

  The door body 9 of the present embodiment is configured to cover the whole of the front part of the cleaning tank 2 in the vertical width direction and the whole of the horizontal width direction. Is provided.

  In addition, the operation panel P (refer FIG. 2) which instruct | commands the various information regarding a washing | cleaning operation is equipped in the upper location of the front-end part of the washing tank 2, ie, the back side location of the upper side part of the door body 9. The cleaning tank 2 is pulled out, information on the cleaning operation is input on the operation panel P, and then the cleaning tank 2 is stored, so that the operation control unit (not shown) has the cleaning tank position sensor 53. (See FIG. 7), the storage of the cleaning tank 2 in the cleaning machine main body 1 is detected, and based on the information input on the operation panel P, the cleaning pump and the heater for heating are operated to execute the cleaning operation. It is configured as follows.

  Further, in addition to the above-described cleaning tank position sensor 53 that detects that the cleaning tank 2 is in the storage state, a lock device 71 that locks the cleaning tank 2 in the storage state is provided. The washing operation is executed while confirming that the container is in the storage state. The lock device 71 will be described later in detail.

  As shown in FIG. 3, the dishwasher S of the present embodiment is installed below the kitchen counter C of the system kitchen in a state of being aligned with an installation body D such as a drawer-type storage unit or a fixed panel. Thus, the surface of the door body 9 is configured to have the same design with the same color tone as the surface of the front surface portion E (see FIG. 8A) of the installation body D. In FIG. 3, a case where a drawer-type storage unit is disposed as the installation body D below the dishwasher S is illustrated.

[Configuration of locking mechanism]
Specifically, as shown in FIG.
(A) A lock body (lock pin) (FIG. 4A) that is disposed in the cleaning tank (hatched portion in FIG. 4A) 2 and is a locking piece in one of the left and right directions of the door body 9 in front view. The locking device 71 (FIG. 4A) is configured so that it can freely perform the operation of projecting the projecting lock body 41 to the position before projecting the projecting lock body 41. And other hatched parts in FIG.
(B) A locking body (locking member) 42 disposed on the cleaning machine main body 1 and contacting the lock body 41 to prevent the cleaning tank 2 from being pulled out from the cleaning machine main body 1 is provided.

  As described above, the lock body (lock pin) 41 protrudes from the lock device 71 in the laterally outward direction (right direction in the first embodiment) and is in a protruding state, and is also retracted leftward and is in a state before protruding. It operates to return to the (reverse state).

  Further, the locking body 42 is pulled out of the cleaning tank 2 stored in a predetermined storage position of the cleaning machine main body 1 (in this embodiment 1, the innermost position of the cleaning machine main body 1) to the first pull-out position. Sometimes, it comes into contact with the lock body 41 in the protruding state and functions to prevent the cleaning tank 2 from being further pulled out therefrom.

  When performing the washing operation in the dishwasher S, the lock device 71 keeps the lock body (lock pin) 41 in the protruding state, and maintains the locked state so that the user can wash the washing tank 2 during the washing operation. The leakage of the washing water from the washing tank 2 due to careless withdrawal is prevented.

  That is, in the state where the cleaning tank 2 is pulled out to the first drawing position, the inner lid 10 that opens and closes the upper surface opening 4 of the cleaning tank 2 does not close the upper surface opening 4 of the cleaning tank 2, but the inner lid 10 Is configured so as to cover the upper surface opening 4 of the cleaning tank 2 from above so that the cleaning water does not leak from the upper surface opening 4 of the cleaning tank 2, and the user can further clean the cleaning tank 2 from the first drawing position. Even if it is going to draw out, the washing tank 2 cannot draw out any more, and the leakage of the washing water from the washing tank 2 is prevented.

FIG. 4B shows that when the cleaning tank 2 is pulled out to the first pull-out position, the lock body 41 and the tip 43 of the locking body (locking member) 42 abut ( The engaged state is shown.
Thus, when the locking device 71 is in the locked state, the withdrawal of the cleaning tank 2 is restricted.

  When the cleaning operation is finished, as shown in FIG. 5A, the lock device 71 is brought into an unlocked state in which the lock body (lock pin) 41 is maintained in the retracted state by an operation control unit (not shown).

When the lock device 71 is in the unlocked state, the lock body (lock pin) 41 does not engage with the locking body 42, so that the cleaning tank 2 can be pulled out from the cleaner main body 1.
FIG. 5B shows a state in which the cleaning tank 2 is pulled out from the cleaning machine main body 1 in the unlocked state of the locking device 71 in which the lock body 41 is kept in the retracted state.

[Unlocking during normal operation]
In the dishwasher S of the first embodiment, when the washing tub 2 is pushed into the innermost side of the washing machine main body 1 and is at a predetermined storage position (the innermost), the distance between the lock pin 41 and the locking body 42. G (see FIG. 4A) becomes 20 mm, the cleaning tank 2 is pulled out from its predetermined storage position by 20 mm, and the state where the lock pin 41 is in contact with the locking body 42 is pulled out to the first pulling position. It is comprised so that it may become a state (state shown to FIG. 4B).

  As shown in FIGS. 7A and 7B, the cleaning tank position sensor 53 is provided with a mounting plate 52 at the rear end of the cleaning tank 2, and the cleaning tank position sensor 53 is fixed to the mounting plate 52. In addition, a lever 54 is swingably attached in the vicinity of the cleaning tank position sensor 53. Further, a protrusion 56 for pressing the lever is formed on the mounting plate 55 of the rail 7 of the cleaning machine body 1 at a position facing the lever 54.

  The cleaning tank position sensor 53 detects whether or not the cleaning tank 2 is at a predetermined storage position (the innermost position). For example, the cleaning tank position sensor 53 is a photocoupler in which a light projecting unit 53a and a light receiving unit 53b are arranged to face each other. Become.

  Then, as shown in FIG. 7 (a), when the lever 54 is separated from the projection 55 and is positioned between the light projecting unit 53a and the light receiving unit 53b, the output of the light receiving unit 53b is turned off. It is detected that the tank 2 is drawn forward from the predetermined storage position (the deepest), and as shown in FIG. 7B, the lever 54 is pressed by the projection 55 to receive the light projecting part 53a and the light receiving part. Since the output of the light receiving unit 53b is turned on when the unit 53b is separated from the unit 53b, it is configured to detect that the cleaning tank 2 is stored in a predetermined storage position.

  In the first embodiment, the lever 54 is separated from the protruding portion 55 when the cleaning tank 2 is pulled forward from a predetermined storage position (backmost) by a predetermined detection pull-out amount H (for example, 3 mm) or more. It is located between the light projecting unit 53a and the light receiving unit 53b, the output of the light receiving unit 53b is turned off, and it is detected that the cleaning tank 2 has been drawn forward from the predetermined storage position (the backmost).

  When the cleaning tank 2 is pulled out from the predetermined storage position (the deepest) by a predetermined detection pull-out amount H (for example, 3 mm) or more, the operation control unit (not shown) stops energizing the pump. In the state where the cleaning tank 2 is pulled out from the predetermined storage position (the deepest) by a predetermined detection pull-out amount H (for example, 3 mm), the upper surface opening 4 of the cleaning tank 2 is closed by the inner lid 10. .

  Further, when the cleaning tank 2 is pulled forward, the inner lid 10 rises and is detached from the upper surface opening 4 of the cleaning tank 2, but the inner lid 10 covers the upper surface opening 4 of the cleaning tank 2 from above and cleans it. Since the cleaning water is configured not to leak from the upper surface opening 4 of the tank 2, the cleaning water does not leak from the upper surface opening 4 of the cleaning tank 2.

  The operation control unit detects that the rotational speed of the pump has decreased to a rotational speed N such that the washing water does not leak from the upper surface opening 4 of the washing tank 2 even when the inner lid 10 is not present due to the stop of energization of the pump. Then, the operation control unit retracts the lock pin 41 and puts the lock device 71 into the unlocked state. Thereby, the locked state by the locking device 71 is released, and as shown in FIG. 5B, the cleaning tank 2 can be pulled out to the front.

[Unlocking during non-steady state]
The dishwasher S is provided with a case where the lock cannot be released at the above-described steady state due to a failure of the lock device or a power failure. The washing tub 2 can be pulled out from the dishwasher main body 1 even in a protruding state protruding in the laterally outward direction (right direction in the present embodiment).

  As shown in FIG. 8A, the dishwasher S is installed with a gap EG (for example, 2 mm) between the front surface E of the installation body D and the door body 9. Further, the thickness ED of the front surface portion E of the installation body D is set to 18 mm, for example.

  Since the members constituting the dishwasher S are somewhat elastically deformed, the washing tub 2 is configured to be movable in the horizontal direction with respect to the dishwasher main body 1 at a position above the rail 7 and is provided with a lock pin. At the height position where 41 is disposed, the washing tub 2 is configured to be movable in the left-right direction (horizontal direction) by a predetermined distance E21 (for example, 3 mm) with respect to the dishwasher main body 1. (See FIG. 8B.)

  In the state where the washing tub 2 is housed in the predetermined storage position (the deepest) as shown in FIG. 8A, the door body 9 of the dishwasher S and the front part of the installation body D can be moved to the left. Since E interferes with the cleaning tank 2, the cleaning tank 2 can be shifted to the left only by a distance corresponding to a gap EG (for example, 2 mm) between the front surface portion E of the installation body D and the door body 9.

  However, as shown in FIG. 4A, there is a gap G (for example, 20 mm) between the lock pin 41 and the locking body 42 in a state where the cleaning tank 2 is stored in the predetermined storage position (the deepest). As shown in FIG. 8B, the cleaning tank 2 can be pulled forward by G (for example, 20 mm).

  As shown in FIG. 8B, in the state where the washing tank 2 is pulled forward by G (for example, 20 mm), the door body 9 of the dishwasher S and the front surface portion E of the installation body D do not interfere with each other. It is possible to move in the direction by a predetermined distance E21 (for example, 3 mm).

  Positional relationship between the lock body (lock pin) 41 and the locking body 42 when the cleaning tank 2 is moved leftward by E21 (for example, 3 mm) with the cleaning tank 2 pulled forward by G (for example, 20 mm). Is shown in FIGS. 4C and 6A.

  As shown in FIGS. 4C and 6A, in the state where the washing tub 2 is moved leftward by E21 (for example, 3 mm) with respect to the dishwasher main body 1, the lock body (lock pin) 41 and the locking body Since the tip 43 is in a positional relationship that does not overlap with the front view, the cleaning tank 2 can be pulled forward.

  When the cleaning tank 2 is pulled forward from the state shown in FIGS. 4C and 6A, the lock body (lock pin) 41 is inclined to the inclined portion 44 (that is, the figure) of the lock body 42 as shown in FIGS. 4D and 6B. 6A and 6B, the lock body (lock pin) 41 is brought into contact with the inclined portion 44 formed on the left side surface of the lock body 42, but the lock body (lock pin) 41 pulls the lock body 42 by pulling the cleaning tank 2 with a slightly strong force. Since the inclined portion 44 can be moved to the front side (the direction in which the cleaning tank 2 is pulled out) while being elastically deformed outward (rightward), the cleaning tank 2 is pulled out from the cleaning tank body 1 as shown in FIG. 4E. Can do.

  In addition, by providing the locking body 42 with the inclined portion 44, the resistance when the cleaning tank 1 is pulled out increases by the presence of the inclined portion 44, and the cleaning tank 2 is carelessly biased to the left side. If the cleaning tank 2 is not moved to the near side with the intention of pulling out the cleaning tank 2, the cleaning tank 2 will not be pulled out easily, preventing leakage of cleaning water. Can be ensured.
