dish washer

technical field

The invention relates to an embedded dish washer for washing and drying tableware.

Background technique

Conventionally, as such a dishwasher, a dishwasher having a structure as shown in FIGS. 9 , 10A, and 10B has been proposed (for example, refer to Patent Document 1).

Fig. 9 is a side sectional view of a conventional dishwasher. 10A is a sectional view of the vicinity of the handle in a locked state of the conventional dishwasher. Fig. 10B is a cross-sectional view of the handle in an unlocked state of the dishwasher. In addition, FIG. 9 exemplifies the structure in which the dishwasher is accommodated in the kitchen unit and the washing tank 3 is pulled out forward (to the left in the drawing).

As shown in FIGS. 9 to 10B , the conventional dishwasher includes a housing 2, a cleaning tank 3, a storage switch 3a, a door body 4, a tableware basket 7, a cleaning nozzle 8, a cleaning pump 9, an operation panel 11, and a handle 11a. . The casing 2 has a front opening 1 at the front, and accommodates a cleaning tank 3 inside. The washing tank 3 has a front door 4 covering the front opening 1 of the casing 2, an upper opening 5 on the upper surface, and a cutlery basket 7 inside. Furthermore, the cleaning tank 3 has guide rails 10 below the left and right outer sides, and the cleaning tank 3 is supported in the casing 2 in a state capable of parallel movement in the front-back direction. The cutlery basket 7 includes upper and lower layers for receiving cutlery items 6 . The cleaning nozzle 8 is rotatably provided below the tableware basket 7 and cleans the bottom surface of the tank 3 . The washing pump 9 pressurizes the washing water accumulated in the washing tank 3 to the washing nozzle 8 to spray the washing water accumulated in the washing tank 3 . Thereby, the tableware 6 accommodated in the tableware basket 7 is washed.

In addition, an operation panel 11 is provided above the front surface of the door body 4 . The handle 11a is provided at the center of the operation panel 11, and the user can hook the handle 11a and pull out the washing tub 3 from the front. In addition, a handle lever 14 is provided inside the handle 11 a so that it can turn upward, and this handle lever 14 is supported by the door body 4 . And, when pulling out the cleaning tank 3, the user rotates the handle lever 14 around the rotation shaft 14a by an operating angle θ1 (see FIG. 10B ). At this time, the movement of the handle bar 14 is transmitted to the locking mechanism (not shown) arranged along the side wall of the cleaning tank 3 through the linkage bar 15 and the locking piece 15a whose end is fixedly connected to the handle bar 14 . Thereby, the user can release the lock of the cleaning tank 3 and pull out the cleaning tank 3 from the casing 2 .

In addition, a handle switch (not shown) is provided near the handle 11 a to detect the operation of the handle lever 14 . In addition, a storage switch 3 a is provided at the rear of the cleaning tank 3 to detect the storage state of the cleaning tank 3 .

In addition, when pulling out the washing tank 3 during the washing operation, the control unit (not shown) detects the rotation operation of the handle lever 14 using the handle switch. Accordingly, the control unit stops the operation of the cleaning pump 9 before the cleaning tank 3 is pulled out. Furthermore, the control unit performs control so that the washing water from the washing nozzle 8 is not splashed from the washing tank 3 to the outside of the casing 2 . Furthermore, the control unit controls the storage switch 3 a so that the cleaning operation is not performed in a state where the cleaning tank 3 is not stored in the casing 2 .

Next, the operation and function of the conventional dishwasher will be described.

First, when using the dishwasher, the user grabs the handle 11 a integrally formed with the door body 4 and pulls the washing tub 3 forward from the casing 2 . Then, the tableware 6 is arranged and accommodated in the tableware basket 7 from the upper opening 5 of the washing tank 3 .

When storage of tableware 6 is completed, the user returns washing tub 3 to housing 2 . When the cleaning tank 3 returns to the housing 2 , the inner cover 12 waiting in the upper space of the housing 2 is lowered while moving backward through the link mechanism 13 arranged on the left and right side surfaces of the housing 2 . Then, the upper opening 5 of the cleaning tank 3 is closed with the inner cover 12 . Thus, the inner lid 12 prevents the washing water sprayed from the washing nozzle 8 from splashing out of the washing tank 3 during the washing operation of the tableware 6 .

Next, when the user starts the operation of the dishwasher, the controller (not shown) heats the washing water with the heater 16 arranged at the bottom of the washing tank 3 . Then, while heating the washing water, the washing pump 9 is operated to spray the washing water from the washing nozzle 8 toward the tableware 6 . Thereby, the washing|cleaning process of washing off the dirt of tableware 6 is performed.

Next, a rinsing step of rinsing the tableware 6 is performed. Thereafter, a drying step is performed in which air in the cleaning tank 3 is heated by the heater 16 and air is sucked and exhausted by an air blower (not shown) to dry the inside of the cleaning tank 3 .

In the above manner, the operation of the conventional dishwasher is completed.

However, in the state where the structure of the above-mentioned conventional dishwasher is housed in the kitchen unit, it is necessary to arrange the operation panel 11 and the handle 11a including the handle switch on the front surface. Therefore, the design of the overall kitchen is restricted. Specifically, depending on the type of the kitchen unit, it cannot match the design of doors such as drawer storage on the left and right sides of the dishwasher. As a result, there exists a problem that the design property of a whole kitchen is impaired.

Therefore, in order to match the design of the front surface of the dishwasher to the design of the left and right doors of the kitchen unit, a structure in which the operation panel 11 and the handle 11a are removed from the front surface is considered. In this case, detection devices such as a handle switch provided near the handle 11a cannot be provided. In this case, instead of the detection device, the storage switch 3 a for detecting the storage state of the cleaning tank 3 such as completion of storage and pull-out movement can be used for control. However, when the cleaning tank 3 is pulled out during the cleaning operation, the control unit performs control such as stopping the cleaning pump 9 after the storage switch 3 a detects the movement of the cleaning tank 3 . Therefore, the stop operation of the washer pump 9 is delayed. As a result, there is a problem that the washing water sprayed from the washing nozzle 8 splashes from the washing tank 3 to the outside of the casing 2 due to the inertial force of the rotating washing pump 9 .

Embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited to this embodiment.

(Embodiment 1)

Next, the configuration of the dishwasher according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 5 .

Fig. 1 is a side sectional view of a dishwasher according to Embodiment 1 of the present invention. Fig. 2 is a side cross-sectional view of an initial state in which the washing tank of the dishwasher is pulled out from the housing. Fig. 3 is a front sectional view of the dishwasher according to Embodiment 1 of the present invention. Fig. 4 is a side cross-sectional view of the dishwasher in a state where a shielding plate has moved to the rear. Fig. 5 is a side cross-sectional view of a process in which the washing tank of the dishwasher is accommodated in the casing.

First, as shown in FIGS. 1 and 2 , the dishwasher of this embodiment at least includes a housing 17 housed in the integrated kitchen, a cleaning tank 20 , a storage switch 20 a , a door body 21 , a tableware basket 27 , a cleaning nozzle 28 , and a washing machine. The pump 30, the handle 23, the operation part 24, the shielding plate 35, etc. are provided. The housing 17 has a front opening 18 on the front surface, and a washing tank 20 is housed in the housing 17 . The washing tub 20 is provided to be movable in the front-rear direction through the front opening 18, and accommodates items to be washed such as tableware 19 and the like. Furthermore, the cleaning tank 20 is supported in the casing 17 so as to be drawn out in the front-rear direction along the guide rails 26 erected on the inside of both side surfaces of the casing 17 in a substantially horizontal (including horizontal) direction. In addition, a door 21 is provided in front of the washing tank 20 to cover the front opening 18 of the housing 17 when the washing tank 20 is moved rearward and stored in the housing 17 .

In addition, the door body 21 includes an operation panel 25 having an operation portion 24 protruding inwardly from an upper inner surface, a decorative panel 22 , a handle 23 , and the like. In addition, in order to facilitate setting operations such as selection of a washing program in a state where the washing tank 20 is pulled out, the operation unit 24 is provided above the dishwasher. The decorative plate 22 of the door body 21 is fixed on the front surface of the operation panel 25, for example covering the entire front surface of the dishwasher. A user grasps the handle 23 and operates to open and close the door body 21 including the decorative panel 22 . At this time, the decorative panel 22 and the handle 23 are configured with the same design and style as the door for the drawer storage of the integrated kitchen. Thereby, the uniformity of the design of the whole kitchen can be realized.

In addition, the cleaning tank 20 has an upper opening 31 on the upper surface, and a cutlery basket 27 of, for example, a two-tiered upper and lower structure for accommodating tableware 19 is arranged inside the cleaning tank 20 . The washing nozzle 28 is rotatably provided below the dish basket 27 and at the bottom of the washing tank 20 .

The control unit 25 a is provided on the back side of the operation panel 25 of the door body 21 (washing tub 20 ). The controller 25 a circulates the washing water with the washing pump 30 while heating the washing water stored in the washing tank 20 with the heater 29 arranged at the bottom of the washing tank 20 , for example. Then, the control unit 25a performs control to wash the tableware 19 and the like by spraying washing water from the washing nozzle 28 . Thereby, the control part 25a controls a series of operations, such as a washing process, a rinsing process, and a drying process, of a dishwasher.

In addition, an inner cover 32 is disposed above the inside of the casing 17 . The inner cover 32 closes the upper opening 31 of the washing tank 20 when the washing tank 20 is accommodated in the casing 17 . At this time, the inner cover 32 is vertically supported in the case 17 by a pair of left and right parallel link mechanisms 33 including a pair of front and rear links. In addition, a sealing member 34 is provided on the outer periphery of the lower surface of the inner cover 32 to seal the upper opening 31 of the washing tank 20 watertightly when dropped. At this time, the parallel link mechanism 33 has a structure in which when the cleaning tank 20 is pulled out from the housing 17 , the sealing member 34 retreats upward so as not to interfere with the forward and backward movement of the cleaning tank 20 .

In addition, a shielding plate 35 is provided immediately below the inner cover 32 that closes the upper opening 31 of the cleaning tank 20 . The shielding plate 35 covers a part of the upper opening 31 in the front-rear direction over substantially the entire left and right (including the whole) when the cleaning tank 20 is housed in the casing 17 . At this time, the shielding plate 35 is configured to be always disposed on the door body 21 side at the initial stage when the cleaning tub 20 is pulled out. Thus, the shielding plate 35 prevents the washing water from splashing from the washing tank 20 to the outside of the housing 17 at the initial stage when the washing tank 20 is pulled out. At this time, the support part 36 which supports the shielding board 35 so that the shielding board 35 can move back and forth is provided along the front-back direction in the left-right upper part in the washing tank 20. As shown in FIG. This makes it easy to move the shielding plate 35 . Moreover, by providing the support part 36 only in the upper part of the washing tank 20, the volume of the tableware 19 accommodated in the dish basket 27 in the washing tank 20 can be maintained at the same level as the conventional capacity. Furthermore, by moving the shielding plate 35 back and forth, it is possible to prevent the shielding plate 35 from getting in the way when the user puts tableware 19 into and takes out the washing tank 20 .

That is, in the dishwasher of the present embodiment, in order to enable the shielding plate 35 to move in the front-rear direction, the support portion 36 of the shielding plate 35 is provided integrally with the side inner wall of the washing tank 20 so as to move from left to right along the front-rear direction. Protruding protrusions on the inner wall. Thereby, the support portion 36 can be easily formed when the cleaning tank 20 is formed. In addition, operability such as cleaning in cleaning tank 20 can be maintained favorably.

In addition, the shielding plate 35 is configured as a flat plate as a whole, and has upper protrusions 35a abutting against the inner cover 32 at two left and right positions on the upper surface of the front end (door body 21 side), and two left and right positions on the lower surface of the front end. It has the lower protrusion part 35b which contacts the support part 36 (refer FIG. 3). Moreover, the support part 36 has the recessed part 36a which becomes the space which the lower protrusion part 35b of the shielding board 35 falls in when the shielding board 35 is located in the door body 21 side. At this time, it is preferable to form the lower surface of the lower protrusion 35b of the shielding plate 35 facing the support portion 36 with the inclined surface 35b1 so that the lower protrusion 35b of the shielding plate 35 falls smoothly into the recess 36a of the support portion 36 . Thereby, when the shielding plate 35 moves, the lower protruding portion 35b of the shielding plate 35 can be smoothly dropped into or pulled out from the recessed portion 36a of the support portion 36 along the inclined surface 35b1.

Next, the reason why the shielding plate 35 is always arranged at the position on the door body 21 side of the washing tank 20 at the initial stage of the washing operation in the dishwasher according to the present embodiment will be described.

First, as shown in FIG. 4 , for example, when the shielding plate 35 moves to the rear of the washing tank 20 when the tableware is placed in the cutlery basket 27 , when the washing tank 20 is housed, it is shielded as shown in FIG. 5 . The upper protrusion 35 a of the plate 35 abuts against the front end of the inner cover 32 . Then, as the cleaning tank 20 is accommodated in the casing 17 , the shielding plate 35 relatively moves to the front side, that is, the door body 21 side. Further, when the shielding plate 35 is moved and arranged at the position on the door body 21 side, the lower protrusion 35b of the shielding plate 35 falls into the recessed portion 36a of the support portion 36 along the inclined surface 35b1. Thereby, the contact|abutment of the upper protrusion part 35a of the shielding plate 35 and the inner cover 32 is eliminated. As a result, when the inner cover 32 closes the upper opening 31 of the washing tub 20 , the upper protrusion 35 a of the shielding plate 35 does not interfere with the inner cover 32 . That is, during the washing operation of the dishwasher, the shielding plate 35 is always arranged at a position on the door body 21 side of the washing tub 20 .

The dishwasher of this embodiment is comprised as mentioned above.

Next, the operation and function of the dishwasher according to the present embodiment up to the washing operation will be described.

First, the user grasps the handle 23 provided on the decorative panel 22 of the door body 21 to pull out the cleaning tank 20 . Thereby, the user can operate the operation part 24 of the operation panel 25 provided in the inner surface of the door body 21 from above.

Next, the user puts tableware 19 into the tableware basket 27 and injects detergent into the washing tank 20 . At this time, the cleaning program and the like are set through the operation unit 24 of the operation panel 25 . Then, the cleaning tank 20 is accommodated in the casing 17 . At this time, in the present embodiment, the decorative panel 22 of the door body 21 is configured in the same design as the door of the integrated kitchen housed in the state where the washing tank 20 is housed in the casing 17 . Therefore, the uniformity of the design of the whole kitchen can be maintained.

In addition, as described above, when placing the tableware 19 in the tableware basket 27, the user can make the shielding plate 35 covering a part of the upper opening 31 of the washing tank 20 follow the support provided in the washing tank 20 without getting in the way. The portion 36 moves back and forth. At this time, for example, when the cleaning tank 20 is accommodated in the casing 17, when the shielding plate 35 moves to the rear of the cleaning tank 20 as shown in FIG. The lower protruding part 35b of the front part is erected and inclined to the rear. Thereby, the upper protrusion part 35a of the shielding plate 35 becomes the height which abuts on the inner cover 32. As shown in FIG. Therefore, when the user pushes the cleaning tank 20 into the casing 17, as shown in FIG. As a result, the state where the upper protrusion 35 a of the shielding plate 35 is in contact with the inner cover 32 remains, and only the cleaning tank 20 moves into the housing 17 .

Then, when the cleaning tank 20 is housed at a predetermined position in the casing 17 , the lower protrusion 35 b of the shielding plate 35 falls into the recess 36 a provided in the support portion 36 . Accordingly, the flat shielding plate 35 is parallel to the support portion 36 . As a result, the upper protrusion 35 a of the shielding plate 35 is released from contact with the inner cover 32 , and the shielding plate 35 is disposed at a position on the door body 21 side. At this time, the shielding plate 35 smoothly falls into the recessed portion 36a of the support portion 36 through the inclined surface 35b1 of the lower surface of the lower protrusion portion 35b. Accordingly, it is possible to prevent the occurrence of collision sound between the shielding plate 35 and the support portion 36 . In addition, the inclined surface may have an inclined structure in which the shielding plate 35 falls forward and downward from the vicinity of the front end of the support portion 36 . In addition, instead of these inclined surfaces, a cushioning member such as an elastic member such as rubber may be provided at the collision portion between the shielding plate 35 and the support portion 36 . Thereby, the collision sound of the shielding plate 35 and the support part 36 can be suppressed.

Next, the inner cover 32 is dropped to a predetermined position of the washing tank 20 by the parallel link mechanism 33 . As a result, the upper opening 31 of the cleaning tank 20 is hermetically sealed and covered with the sealing member 34 via the inner cover 32 . At this time, the contact between the inner cover 32 and the shielding plate 35 has already been released. Therefore, the upper opening 31 of the washing tub 20 can be reliably closed without the inner cover 32 being obstructed by the shielding plate 35 .

Next, when the cleaning tank 20 is housed in the housing 17, the control unit 25a detects that the storage of the cleaning tank 20 is completed using the storage switch 20a. Then, the cleaning operation is started according to the cleaning program set by the operation unit 24 .

As described above, the operation of the dishwasher of the present embodiment up to the washing operation is executed, and the subsequent washing operation is performed.

Next, the main point of this embodiment, that is, the operation and function of the dishwasher when the user pulls out the washing tub 20 during the washing operation will be described. In addition, the operation of pulling out the washing tank 20 during the washing operation refers to, for example, when adding tableware 19 to be washed or when the user checks the storage state of the tableware 19 .

In this case, the dishwasher of the present embodiment is not provided with a handle switch. Therefore, the control unit 25a stops the cleaning operation of the cleaning pump 30 after detecting the storage state of the cleaning tank 20 by the storage switch 20a, that is, the storage completion or the pull-out movement of the cleaning tank 20 . That is, when the cleaning tank 20 is pulled out during the cleaning operation, the control unit 25 a stops the operation of the cleaning pump 30 after detecting the movement of the cleaning tank 20 . Therefore, the stop operation of the washing pump 30 tends to be delayed, and the washing tub 20 is pulled out, for example, in a state where washing water is sprayed from the washing nozzle 28 . At this time, the washing pump 30 cannot be stopped immediately due to the inertial force of the motor of the washing pump 30 , and the washing water sprayed from the washing nozzle 28 may splash from the washing tank 20 to the outside of the casing 17 .

Therefore, the dishwasher of this embodiment is provided with the shielding plate 35 which can move in the front-back direction and covers a part of the upper opening part 31 of the washing tank 20. As shown in FIG. Furthermore, regardless of where the shielding plate 35 is arranged on the upper opening 31 of the washing tub 20 , it can return to the position on the door 21 side when the washing tub 20 is housed in the casing 17 as described above. That is, even if the cleaning tank 20 is pulled out during the cleaning operation, the shielding plate 35 is always arranged on the door body 21 side at least at the initial stage of pulling out the cleaning tank 20 . Therefore, the shielding plate 35 prevents the washing water sprayed from the washing nozzle 28 from splashing out of the washing tub 20 . Accordingly, it is possible to prevent washing water from splashing from washing tank 20 to the outside of housing 17 . In addition, even if the washing water splashes into the housing 17 from the upper opening 31 of the washing tank 20 on the side where the shielding plate 35 is not present, the washing water can be treated in the housing 17 . Therefore, washing water does not splash from washing tank 20 to the outside of housing 17 .

As described above, even if the dishwasher according to the present embodiment does not provide a handle switch, it is possible to avoid splashing of washing water from the washing tub to the outside of the casing when the washing tub is pulled out during washing operation. Thereby, the handle switch becomes unnecessary, and a structure can be simplified. In addition, a decorative panel having the same design as the door of the housed integrated kitchen can be provided on the front surface as the door body. As a result, a dishwasher excellent in usability and design can be realized.

(Embodiment 2)

Next, the dishwasher of Embodiment 2 of this invention is demonstrated using FIG.6 and FIG.7. In addition, the same code|symbol is attached|subjected to the part which is the same as or equivalent to Embodiment 1, and the description is abbreviate|omitted.

6 is a side cross-sectional view of an initial state in which the washing tank of the dishwasher according to Embodiment 2 of the present invention is pulled out from the housing forward. Fig. 7 is a front sectional view of the dishwasher according to Embodiment 2 of the present invention.

The dishwasher of the present embodiment differs from the dishwasher of Embodiment 1 in that the shielding plate 40 is constituted by a small dish basket 41 having a basket cover 41 a. Thereby, the volume of the washing tank 37 can be enlarged, and the dish basket 38 can be used effectively.

That is, as shown in Fig. 6 and Fig. 7, the dish washer of the present embodiment is equipped with a cutlery basket 38 of upper and lower two-layer structure in the washing tank 37, and a shielding plate 40 including a small cutlery basket 41 is arranged. The cutlery basket 41 moves in the front-rear direction along the support portion 39 provided on the upper portion of the cutlery basket 38 and has a basket cover 41a. Moreover, the support part 39 of the cutlery basket 38 is integrally comprised with the cutlery basket 38 so that it may be located in the vicinity of the upper opening part 31 of the washing tank 37 at the upper part of the cutlery basket 38. As shown in FIG.

At this time, similarly to Embodiment 1, the shielding plate 40 is provided with the upper protrusion part 40a and the lower protrusion part 40b. Moreover, the dish basket 38 is arrange|positioned so that the gap 39a corresponding to the recessed part of Embodiment 1 may be formed between the support part 39 and the front inner wall surface of the washing tank 37. As shown in FIG. In addition, the other structure of a dishwasher is the same as that of Embodiment 1. As shown in FIG.

The dishwasher of this embodiment is comprised as mentioned above.

According to the dishwasher of this embodiment, the support part 39 is integrally provided in the upper part of the dish basket 38. As shown in FIG. Therefore, it is not necessary to provide a protruding support portion or the like on the side wall of the cleaning tank 37 as in the first embodiment. Thereby, the size of the left-right direction of the cutlery basket 38 can be made as close as possible to the size of the inner wall of the washing tank 37. As shown in FIG. As a result, the storage capacity of cutlery 19 stored in cutlery basket 38 can be increased. In addition, when performing maintenance or the like, it is easy to handle when taking out and putting in the dish basket 38 in order to remove the washing nozzle 28 .

Moreover, according to the dishwasher of this embodiment, the shielding plate 40 is comprised with the small-sized dish basket 41 which has the basket cover 41a. Thereby, small tableware can be accommodated in the small tableware basket 41, and the storage capacity of the tableware to be washed in the dishwasher can be increased. In addition, the small cutlery basket 41 constituting the shielding plate 40 can be used as a moving basket that always returns to the washing position on the door body 21 side during the washing operation.

In addition, the dishwasher of this embodiment is provided with the shielding plate 40 which can move in the front-back direction. Moreover, similarly to the shielding plate 35 of Embodiment 1, when the cleaning tank 20 is accommodated in the casing 17, the shielding plate 40 can be placed in the cleaning tank 20 no matter where the upper opening 31 of the cleaning tank 20 is placed. 37 returns to the position on the side of the door body 21 when it is accommodated in the casing 17. That is, even if the cleaning tank 37 is pulled out during the cleaning operation, the lower protrusion 40b of the shielding plate 40 always falls into the gap 39a and is disposed on the door 21 side at least at the initial stage of pulling out the cleaning tank 37 . Therefore, the shielding plate 40 prevents the washing water sprayed from the washing nozzle 28 from splashing out of the washing tub 20 . Accordingly, it is possible to prevent washing water from splashing from washing tank 37 to the outside of casing 17 .

In addition, the structure of the shielding plate and the support part demonstrated in Embodiment 1 and Embodiment 2 is not limited to the structure described respectively, Of course, it can also combine suitably and comprise.

(Embodiment 3)
