Description

Dishwasher {DISHWASHER}

The present invention relates to a dishwasher for washing dishes by spraying washing water from a washing nozzle, and more particularly to a built-in type dishwasher.

Conventionally, when a user tries to take out a washing tub during a washing operation, a built-in type, pull-out dishwasher configured so that the sprayed washing water does not flow out of the washing tub, for example, is disclosed in Japanese Patent Laid-Open No. 2007-301065. (hereinafter referred to as Patent Document 1).

Hereinafter, a conventional dish washing machine disclosed in Patent Document 1 will be described with reference to FIG. 8 .

8 is a side cross-sectional view of a conventional dishwasher.

Also, Fig. 8 shows a state in which a so-called built-in type dishwasher of a draw-out method is accommodated in the system kitchen. A portion indicated by a two-dot chain line in FIG. 8 indicates a state in which the washing tub is taken out from the main body of the dishwasher.

As shown in FIG. 8 , a conventional dish washing machine includes a dish washing machine main body 101 that opens at least in the front, a washing tank 102 provided in the dish washing machine main body 101, a door 102a, and the like. is composed of The washing tank 102 has an opening in the upper part, and is provided so that it can move freely in the front-back direction (direction toward the opening of the dishwasher main body 101). The door 102a is provided at the front of the washing tub 102 and covers the front of the main body 101 of the dishwasher. In the washing tank 102, a dish basket 104, a washing nozzle 105, and the like are provided. The dish basket 104 mounts and accommodates the dishware 103 to be cleaned. The washing nozzle 105 sprays washing water to the tableware 103 mounted on the dish basket 104 to clean it.

In addition, a micro switch 106 , a geared motor 107 , and the like are disposed behind the washing tub 102 in the dishwasher main body 101 . The micro switch 106 detects the movement of the washing tank 102 in the front-rear direction. The geared motor 107 operates so as to restrict the movement of the cleaning tub 102 at the first restraining position and the second restraining position. And while the geared motor 107 restricts the movement of the washing tub 102, even if the micro switch 106 detects that the washing tub 102 has moved from the first restraining position to the second restraining position, Within a predetermined time, it is comprised so that the restraint of the washing tank 102 by the geared motor 107 may not be cancelled|released.

With this configuration, even if the user tries to pull out the washing tub 102 by holding the handle 102b of the door 102a, the washing tub 102 cannot be pulled out in front of the second restraining position for at least a predetermined period of time. Thereby, the washing water sprayed from the washing nozzle 105 is prevented from coming out from the washing tank 102 or from splashing out to the user.

Next, for example, the conventional dishwasher in another example currently disclosed by Unexamined-Japanese-Patent No. 2011-206130 (henceforth, it describes as patent document 2) is demonstrated using FIG.

9 is a side cross-sectional view of an upper door of a conventional dish washing machine according to another example. 9 shows the outline of the handle 113 for taking out the washing tank 111 and the handle switch 115 for detecting that a hand is placed in the handle 113 .

The dish washing machine shown in FIG. 9 includes a washing tub 111 provided to be movable in the front-rear direction in the main body of the dish washing machine, a door 112 provided on the front of the washing tub 111, and the like, similarly to the dishwasher shown in FIG. 8 . have In addition, the dishwasher includes a lock device (not shown), a handle switch 115, and the like. The door 112 has a handle 113 and a handle lever 114 . The handle 113 is provided on the upper portion of the door 112 , and the user puts his or her hand on the handle 113 to take out the washing tank 111 . The handle lever 114 is provided rotatably inside the handle 113 . The lock device locks and unlocks the movement of the washing tank 111 in the front-rear direction. The knob switch 115 detects rotation of the knob lever 114 .

Hereinafter, the operation of the dishwasher will be described in detail.

First, the user puts his hand on the handle 113 to take out the washing tub 111 . At this time, the handle lever 114 is pressed upward and rotates by an angle θ1 about the shaft 114a. Thereby, a space for hanging a hand is formed inside the handle 113 . That is, as long as the user does not rotate the handle lever 114 , a space to hang the hand is not formed inside the handle 113 . Therefore, the washing tank 111 cannot be taken out forward.

Then, the knob switch 115 detects rotation of the knob lever 114 when the knob lever 114 forming the space is rotated by an angle θ3 smaller than the angle θ1.

Next, when the knob switch 115 detects rotation of the knob lever 114, a control device (not shown) unlocks the lock device. In addition, the control device stops the operation of the cleaning pump that ejects the cleaning water from the cleaning nozzle (not shown).

That is, in the dishwasher, when the user puts his/her hand on the handle 113 and rotates the handle lever 114 by an angle θ3, the locking device is released. However, in order to take out the washing tank 111, since the handle lever 114 is rotated to the angle θ1, it is necessary to apply more hands. Therefore, although it is very small, it takes time to take out the washing tank 111 . Then, during that time, the control device stops the cleaning pump and stops spraying the cleaning water from the cleaning nozzle. Thereby, it is possible to prevent the washing water from jumping out of the washing tank 111 to the outside of the device.

However, the structure of the dish washing machine described in Patent Document 1 uses a geared motor, an electromagnetic valve, or the like as a method of locking the movement of the washing tank. In this case, if a power outage occurs during operation of the dishwasher, the lock preventing movement of the washing tub cannot be released. Therefore, even at the time of a power failure, some kind of countermeasure is necessary so that the movement of the washing tank can be unlocked. In addition, geared motors, solenoid valves, and the like that lock the movement of the washing tank consume electric energy, and thus go against the trend of energy saving. In addition, when the user needs to take out the washing tub in a hurry, if the washing tub is locked, there is a problem that the user is embarrassed or feels uncomfortable.

Further, in the configuration of the dishwasher described in Patent Document 2, the user pushes up the handle lever to unlock the lock device and to take out the washing tub. Then, between the angle θ3 to the angle θ1 at which the pull lever is pushed, the control device stops the operation of the cleaning pump. This makes it possible for a user to take out a washing tank. However, usually, a slight time delay occurs after the operation of the cleaning pump is stopped until the injection of the cleaning water from the cleaning nozzle is completely stopped. At that time, there is no problem as long as the speed at which the user takes out the washing tank is more slowly than the time delay described above. However, in a rushed state, if the user puts his or her hand on the handle to forcefully pulls out the washing tub, there is a possibility that the jetting of the washing water may not stop completely. In this case, it is impossible to prevent the washing water from jumping out of the device from the inside of the washing tank.

That is, in the configuration of the conventional dishwasher, there is a problem that the splashing of the washing water from the inside of the washing tank to the outside of the device cannot be reliably prevented in response to the user's various usages.

The present invention controls the taking-out speed of the washing tub when the user takes out the washing tub during the washing operation. Thereby, it is possible to provide a dishwasher capable of preventing the sprayed washing water from coming out of the washing tank to wet the surroundings.

That is, the dish washing machine of the present invention includes a case with an open front, a washing tub which is freely movable in the front and rear directions in the case and has an open top, and a front surface of the case provided on the front of the washing tub and the washing tub is in the storage position in the case. It has a door that can open and close freely. In addition, a position detecting device for detecting that the washing tub is in the stowed position, a washing device for washing the tableware accommodated in the washing tub, and controlling a series of washing operations of the washing device, and positioning the washing tub from the stowed position It has a control device that stops the operation of the cleaning device when the detection device detects it. Moreover, it has the braking device which generates the braking force which suppresses the take-out speed in at least a part from the storage position of a washing tank to a predetermined position.

According to this configuration, when the user tries to take out the washing tub during the washing operation, the braking device suppresses the taking out speed of the washing tub. And while the braking device is suppressing the take-out speed of the washing tank, the control device completely stops the injection of the washing water. This prevents the sprayed washing water from jumping out of the case. As a result, it is possible to realize a highly reliable dishwasher that does not wet the periphery of the case or the user with the washing water.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dishwasher according to the first embodiment of the present invention will be described below with reference to Figs. Moreover, although this embodiment demonstrates the case where the built-in type dishwasher of a take-out system is accommodated in the system kitchen as an example, it cannot be overemphasized that it is not limited to this.

BRIEF DESCRIPTION OF THE DRAWINGS It is a side cross-sectional schematic diagram which shows the state in which the washing tank of the dish washing machine in Embodiment 1 of this invention was accommodated in the case. Fig. 2 is a schematic side cross-sectional view showing a state in which the washing tank of the dishwasher according to the embodiment is taken out from the case to a predetermined position. Fig. 3 is a side cross-sectional schematic view showing a state in which the washing tank of the dishwasher according to the embodiment is taken out of the case beyond a predetermined position. In addition, in this embodiment, the position where the washing tank shown in FIG. 1 was accommodated completely in the case is demonstrated as a "storage position". In addition, in FIGS. 1-3, the left direction on the figure is demonstrated as the taking-out direction of a washing tank. The same applies to subsequent drawings.

1 to 3 , the dishwasher according to the present embodiment includes a case 1 formed in a box shape and having an open front surface, and is freely installed in the interior of the case 1 in the front-rear direction, and the upper surface This opened washing tank 2 is provided. And the dishwasher is housed in system kitchen K.

The washing tank 2 is suspended on guide rails 3 horizontally arranged inside the side walls of the case 1 and is configured to move in the front-rear direction with a small force. This makes it possible for the user to easily take out the washing tank 2 out of the case 1 or push it into the case 1 . In addition, the washing tank 2 is provided with a dish basket 5 for arranging and accommodating the dishes 4 therein, and a washing device 6 for washing the dishes 4 by spraying washing water. The washing device 6 includes a washing pump 7 for circulating the washing water supplied to the washing tank 2 , a washing nozzle 8 for spraying the washing water pumped from the washing pump 7 to the dishes 4 , etc. is further composed of

The door 9 is provided in the front of the washing tank 2 to open and close freely, and when the washing tank 2 is pushed inside the case 1 and is in the accommodated position, it covers the front surface of the case 1 . . And, on the entire surface of the door 9, a decorative panel 9a of the same design as the door or drawer of the system kitchen K in which the dishwasher is housed is mounted. Moreover, the door 9 is provided with the handle 9b. The handle 9b is held by the user and is used when the cleaning tank 2 is taken out of the case 1 or pushed into the case 1 . And the handle 9b is also comprised with the same design as the door and drawer|drawer of system kitchen K.

In addition, most of the doors of the conventional dishwasher are equipped with a decorative panel of the same design as the door of the system kitchen, but generally the design of the handle is different. Specifically, as described above, in a conventional door, an operation lever such as a handle lever for releasing the lock is incorporated. Moreover, an operation switch, a driving lamp, etc. are arrange|positioned at the door.

However, since the dishwasher of this embodiment does not arrange an operation lever, an operation switch, a driving lamp, etc. on a door, the design of the door 9 can be comprised with the same design as a system kitchen. As a result, at first glance, it is difficult to discriminate that the dishwasher is housed in the system kitchen, and it can be configured with excellent unity.

Further, the central lid 10 is provided on the inner upper portion of the case 1 , and closes the opening of the upper surface of the washing tank 2 . The center lid 10 is provided with a packing 10b on the surface opposite to the opening of the washing tank 2, and is arranged to move up and down freely by a pair of left and right link mechanisms 10a including a pair of front and rear links. . Then, the central lid 10 moves up and down through the link mechanism 10a in accordance with the movement of the washing tub 2 in the front-rear direction. For example, when the washing tub 2 is in the storage position, the upper surface block the opening.

Further, the control device 11 is installed between the washing tank 2 and the door 9 and controls a series of washing operations such as a washing step, a rinsing step, and a drying step of the dishwasher.

The operation unit 12 is provided above the control device 11 , and the user sets a series of operations and the like.

A microswitch 13 serving as a position detecting device is provided on the inside rear side of the case 1 (on the side opposite to the door 9), and detects that the washing tank 2 is taken out and moved from the storage position. The micro switch 13 is connected to the control device 11 . Then, when the movement of the cleaning tank 2 from the storage position is detected by the micro switch 13 , the control device 11 controls the cleaning pump 7 to stop operating.

In addition, the braking device 14 is provided, for example, on the inner side surface of the case 1 , and generates a braking force that suppresses the take-out speed of the washing tank 2 . At this time, on the side surface of the washing tank 2 , a protrusion 15 connected to the braking device 14 is provided.

Specifically, when the cleaning tub 2 is taken out from the storage position, the braking device 14 generates a braking force that suppresses the taking-out speed of the cleaning tub 2 in at least a part from the storage position to the predetermined position. . The predetermined position is not particularly limited, but in the present embodiment, for example, a position where the cleaning water sprayed from the cleaning nozzle 8 does not come out of the case 1 is defined as the predetermined position. A specific location will be described later. That is, when the predetermined position is set as described above, the position of the washing tank 2 from which the washing water does not come out of the case 1 becomes clear. Thereby, when the washing tank 2 is taken out to a predetermined position, the braking force required by the braking device 14 can be made to act on the washing tank 2 by this, for example. As a result, the splashing of the washing water from the washing tank 2 to the outside can be reliably prevented.

Hereinafter, a braking device for a dishwasher according to the present embodiment will be described with reference to FIGS. 4 and 5 .

4 and 5 are schematic diagrams showing the internal structure of the braking device of the dishwasher according to the embodiment. Moreover, FIG. 4 has shown the state of the braking device in the state which the washing tank shown in FIG. 1 was accommodated in the case. That is, the state of the braking device 14 when the washing tank 2 is in the storage position is shown. Moreover, FIG. 5 has shown the state of the braking device in the state in which the washing tank shown in FIG. 2 was taken out from the case to a predetermined position.

As shown in FIGS. 4 and 5 , the braking device 14 includes a case 16 , and a receiving portion 18 and a spring 19 to which the damper 17 and the protrusion 15 engage with the inside of the case 16 . ) and so on. Moreover, the guide part 16a which guides the movement of the receiving part 18 is formed in the side surface of the case 16. As shown in FIG.

The damper 17 has a damper rod 17a that enters and leaves in the moving direction of the washing tank 2 , and constitutes a tension damper that generates a braking force in only one direction. That is, the damper 17 generates a braking force when the damper rod 17a is taken out. On the other hand, when the damper rod 17a is pushed in, no braking force is generated.

The receiving portion 18 of the braking device 14 is swingably mounted in parallel with the side surface of the case 1 with the tip end of the damper rod 17a serving as the swing shaft 17b. The receiving portion 18 has, for example, two guide pins 18a and 18b engaged with the guide portion 16a. Thereby, the receiving part 18 engages with the guide part 16a, and moves along the guide part 16a. Moreover, the receiving part 18 has the recessed part 18c with the lower side recessed, and the recessed part 18c is comprised so that the projection part 15 provided in the washing tank 2 may enter.

The guide portion 16a has a J-shape bent upward on the side of the end 16c opposite to where the damper 17 is disposed, and is formed on the side surface of the case 16 .

In addition, the spring 19 of the braking device 14 is comprised with a tension spring, for example. One end of the spring 19 is locked by a locking portion 16b provided in the case 16 . The other end of the spring 19 is locked by the locking portion 18d provided in the receiving portion 18 above the swing shaft 17b. At this time, the tension of the spring 19 always acts on the locking portion 18d and in the direction in which the damper rod 17a is pushed. This prevents the receiving part 18 from rattling in the guide part 16a. In addition, the tension of the spring 19 acts to reduce or eliminate the resistance of the damper 17 in the pushing direction in which no braking force is generated.

That is, as shown in FIG. 4 , in the state in which the washing tank 2 enters the storage position, the damper rod 17a is pushed into the damper 17 . At this time, the projection 15 enters the concave portion 18c of the receiving portion 18 .

On the other hand, as shown in FIG. 5, in the state in which the washing tank 2 is taken out, it moves in the direction in which the receiving part 18 is taken out together with the protrusion part 15. As shown in FIG. Specifically, the receiving portion 18 moves along the guide portion 16a by the movement of the protruding portion 15 . At this time, the guide pin 18a on the take-out side moves upward by the curve of the J-shaped guide part 16a. Thereby, the receiving part 18 inclines, and the latching|locking of the protrusion part 15 provided in the washing tank 2 and the recessed part 18c shifts. In this case, the spring 19 is in a state of being elongated. However, the receiving portion 18 is in a state in which the guide pin 18a is caught by the curved end of the guide portion 16a by the rotational force received by the spring 19 . And, together with the receiving portion 18, the guide pin 18a is maintained in the locked state.

As described above, the dishwasher of the present embodiment is configured.

Hereinafter, the operation and operation of the dish washing machine having the above configuration will be described.

First, the user takes out the washing tank 2 by holding the handle 9b provided on the door 9 . Next, the dishware 4 is placed in the dish basket 5 and detergent is placed therein. Thereafter, the user selects a driving course by means of a course selection button on the operation unit 12 and presses a driving start button.

Then, the washing tank 2 is pushed in to the storage position in the case 1 . At this time, the center lid 10 moves backward and downward by the link mechanism 10a, and closes the opening of the washing tank 2 . At the same time, it is detected that the cleaning tub 2 is in the stowed position by the microswitch 13 serving as a position detection device. Then, the detection signal detected by the micro switch 13 is transmitted to the control device 11 . Thereby, the control device 11 starts the washing operation of the dishwasher.

Next, when the washing operation is started, the control device 11 opens a water supply valve (not shown) to supply tap water serving as washing water into the washing tank 2 . Moreover, the control device 11 energizes a heater (not shown) to heat the washing water, and performs control such as driving the washing pump 7 . As a result, the dishwasher performs a series of washing operations for washing the dishes 4 accommodated in the washing tank 2 .

Moreover, the dish washing machine according to the present embodiment is configured so that the user can insert and remove the dishes 4 even while the washing operation is being performed as described above. In this case, the user takes out the washing tub 2 by holding the handle 9b provided on the door 9 of the washing tub 2 during the washing operation.

Hereinafter, the operation and action when the washing tank 2 is taken out during the washing operation will be described.

First, when the washing tank 2 is taken out during the washing operation, the microswitch 13 detects the movement of the washing tank 2 from the storage position. Then, when the control device 11 is in the middle of a washing step or a rinsing step of spraying washing water, the power supply to the washing pump 7 is immediately stopped. At this time, the washing pump 7 pressurizes the washing water to the washing nozzle 8 . Therefore, even when the power supply to the washing pump 7 is stopped, the jetting of the washing water from the washing nozzle 8 does not stop quickly due to the residual pressure or the inertial force. That is, the jetting of the washing water from the washing nozzle 8 is completely stopped after a certain period of time has elapsed from the stop of energization to the washing pump 7 .

At this time, the opening of the upper surface of the washing tank 2 is normally closed by the center lid 10 . Therefore, at the beginning of the washing tank 2 being taken out, even when the center lid 10 starts to move upward, the washing tank 2 is sealed by the elasticity of the packing 10b. That is, while the sealing action of the packing 10b is effective, the washing water does not leak.

In addition, as shown in FIG. 2 , if at least the front end of the washing tank 2 is not pulled out ahead of the front end of the case 1 , the washing water jetted from the washing nozzle 8 does not come out of the case 1 . .

Moreover, in this embodiment, as mentioned above, the position where the front end of the washing|cleaning tank 2 was extended to the front end of the case 1 is made into the predetermined position. Thereby, the predetermined position becomes clear as the position of the washing tank 2 where the washing water does not come out of the case 1 .

Therefore, in this embodiment, as specifically shown below, the splashing of washing water is prevented based on the movement time of the washing tank 2 to the said predetermined position.

First, the time from when the micro switch 13 detects the movement of the washing tank 2 by the user's removal to the stop of the jetting of the washing water from the washing nozzle 8 is set as the stop time. Moreover, let the movement time by which the washing tank 2 is taken out to a predetermined position be taken out time. And the take-out time of the washing tank 2 is controlled by the braking device so that the stop time and the take-out time are the same or the take-out time is longer than the stop time. Thereby, the splashing of the washing water out of the case 1 is prevented in advance.

That is, the braking device 14 of the washing tank 2 controls the take-out time by the braking force of the damper 17 . Specifically, when the cleaning tub 2 is taken out from the storage position, the braking device 14 generates a braking force so that it takes a predetermined time or more from the storage position to the predetermined position, thereby reducing the removal time of the cleaning tub 2 . Control.

Next, the operation of the braking device 14 of the present embodiment will be specifically described with reference to FIGS. 4 and 5 .

As shown in FIG. 4 , when the washing tub 2 is taken out from the storage position A, the projection 15 provided in the washing tub 2 moves in the take-out direction. Then, after moving from the storage position A to the position B where the projection 15 to be described later comes into contact with the recess 18c of the receiving portion 18, the receiving portion 18 is pulled by the projection 15 and moves further do. Then, in the damper 17 , the damper rod 17a is pulled out by the recessed portion 18c that moves together with the receiving portion 18 to generate a braking force. In addition, the generated braking force becomes larger when the user tries to take out the washing tub 2 vigorously. On the other hand, when the damper rod 17a is slowly taken out, a large braking force is not generated.

At this time, in this embodiment, as shown in FIG. 4, the width W1 of the recessed part 18c of the receiving part 18 is made larger than the width W2 of the protrusion part 15. As shown in FIG. Thereby, the projection part 15 does not move the receiving part 18 at the beginning of the movement from the storage position A to the position B. Therefore, the braking force by the damper 17 is not generated. Thereby, an increase in the force when the user takes out the washing tub 2 does not occur at the beginning when the greatest force is required. As a result, the user's feeling of use is not impaired at the time of taking out the washing tank 2, and the taking out operation of the washing tank 2 can be performed without a feeling of incongruity.

And as shown in FIG. 5, when the receiving part 18 arrives at the end of the lead-out side of the guide part 16a with the movement of the projection part 15, the curved shape of the J-shaped guide part 16a. The receiving part 18 is inclined in accordance with the Thereby, the engagement of the recessed part 18c and the protrusion part 15 is shifted|deviated. Then, after the lock is displaced, the washing tank 2 is smoothly taken out along the guide rail 3 shown in Figs. 1 to 3 irrespective of the braking device 14 . At this time, the receiving part 18 is hold|maintained in the inclined state shown in FIG. 5 by the tension|tensile_strength of the spring 19. As shown in FIG.

As described above, the braking device 14 operates.

That is, the braking force of the damper 17 of the braking device 14 is applied to the washing tub 2 while the washing tub 2 is taken out from the position B shown in FIG. 4 to the predetermined position C shown in FIG. 5 . . And after the predetermined position C, even if the washing tank 2 is taken out, the braking device 14 does not act at all.

On the other hand, on the other hand, when the washing tub 2 is pushed into the case 1, the protrusion 15 of the washing tub 2 is placed in the recessed part 18c of the receiving part 18 held in an inclined state when taken out. goes in And the receiving part 18 in contact with the protrusion part 15 returns to a storage position simultaneously with the washing tank 2 . At this time, as described above, the damper 17 does not generate a braking force, and the tension of the spring 19 acts on the receiving portion 18 .

In addition, the magnitude of the braking force of the damper 17 may be set so that the stop time of the washing water and the take-out time of the washing tub 2 are the same, or the take-out time is longer than the stop time.

In addition, normally, the stop time from the detection of the micro switch 13 until the stop of jetting of the washing water from the washing nozzle 8 is, for example, about 0.4 seconds. In addition, the predetermined dimension from the storage position of the washing tank 2 to the predetermined position of the washing tank 2 shown in FIG. 2 is 30 mm, for example. Then, in this embodiment, the predetermined time until the washing tank 2 is taken out to a predetermined position from a storage position is made into 0.5 second. In addition, the predetermined time is not limited to this, You may set arbitrarily as long as it is longer than the jet stop time of washing water. Thereby, it is possible to predict the stopping time until the stop of the jetting of the washing water from the washing nozzle 8 and apply a necessary braking force when the washing tank 2 is taken out. As a result, splashing of the washing water from the inside of the washing tank 2 can be reliably prevented.

Here, in JIS S1200:2012, the average moving distance of taking out and opening/closing recommended as a durability test of taking out of a storage unit is 0.25±0.1 m per second. That is, the average speed of taking out and opening is 0.15 m/s - 0.35 m/s. Then, the average time for moving the predetermined dimension 30 mm is 0.2 seconds to 0.09 seconds.

However, when the user actually takes out the washing tub 2 of the dishwasher, the weight of the washing tub 2 is greater than the unloading weight of the storage unit, and there is a tension of the spring 19 of the braking device 14 . Therefore, an actual dish washing machine is provided with a pull-out device (not shown). Therefore, when the washing tank 2 of the dish washing machine is actually taken out, the taking-out resistance increases compared to the JIS storage unit. Thereby, realistically, the take-out time of the washing tank 2 becomes a little long. Then, in this embodiment, the predetermined time for which the washing tank 2 reaches a predetermined position from a storage position is made into 0.5 second or more irrespective of a take-out speed. And the braking force of the braking device 14 is set so that it may approach a predetermined time as much as possible. In addition, the braking force of the braking device 14 changes according to the speed so that the cleaning tub 2 takes out speed when it is fast and becomes small when it is slow. Thereby, when the take-out speed of the washing tank 2 is slow, a braking force is made small, and it is suppressed that taking-out time is extended meaninglessly.

As described above, in the dishwasher of the present embodiment, when the washing tub 2 is taken out from the storage position, the braking device 14 generates a braking force for suppressing the take-out speed in at least a part from the storage position to the predetermined position. have And the braking device 14 suppresses the taking-out speed of the washing tub 2 when the user tries to take out the washing tub 2 during the washing operation. Thereby, while the washing tank 2 is taken out to a predetermined position, the injection of washing water can be stopped completely. As a result, the washing water sprayed from the washing nozzle is prevented from jumping out of the case 1, and it is more reliably prevented that the washing water wets the surroundings.

In addition, in the dishwasher according to the present embodiment, the braking device 14 is configured as a damper 17 . Thereby, consumption of electric energy can be eliminated, and energy saving property can be improved. In addition, when the user tries to take out the washing tub 2 in a hurry, the braking device 14 only applies a braking force to the movement of the washing tub 2 , and does not lock the movement of the washing tub 2 . Therefore, the user's embarrassment or discomfort due to locking of the washing tank 2 or the like is not caused. In addition, the damper 17 of the braking device 14 generates a braking force only in the direction in which the washing tank 2 is taken out. Therefore, when the washing tank 2 is pushed in and accommodated in the case 1, the user does not need to apply extra force. Thereby, the washing tank 2 can be accommodated smoothly.

In addition, the dishwasher of the present embodiment changes the braking force generated by the braking device 14 according to the take-out speed of the washing tub 2 . Therefore, when taking out the washing tank 2 slowly, generation|occurrence|production of a braking force is suppressed, and the user does not need to add extra force. Thereby, it is suppressed that the take-out time of the washing tank 2 is extended meaninglessly. Conversely, when the washing tub 2 is pulled out vigorously, the braking device 14 generates a large braking force, and adjusts the take-out time of the washing tub 2 to be equal to or longer than a predetermined time. That is, by adjusting the take-out speed according to the user's various usages, the washing water is prevented from jumping out of the case 1 . Thereby, for the user, it is possible to provide a dishwasher with improved usability.

Further, in the dishwasher of the present embodiment, the decorative panel and handle of the door 9 are configured according to the design of the door of the system kitchen or the like. That is, in the conventional dishwasher, the decorative panel part was adapted to the design of the door of the system kitchen, but the handle was constituted by the original design of the dishwasher. However, the door 9 of the present embodiment does not need to have a function on the handle. Therefore, it becomes possible to match the whole which matched the decorative panel 9a of the door 9 and the handle 9b to the design of the door of a system kitchen. Thereby, it can be comprised by the system kitchen and the integrated design. As a result, the design of the system kitchen improves.

In addition, although this embodiment demonstrated the example in which the position of the damper 17 with respect to the guide part 16a was provided on the opposite side to the taking-out direction of the washing tank 2 in the braking device 14, it is not limited to this. . For example, the position of the damper 17 may be on the take-out direction side, and may be upward or downward. In addition, the damper 17 may be provided to be inclined. Thereby, the degree of freedom in design is improved.

Moreover, although this embodiment demonstrated the example comprised using a tension damper as the damper 17 of the braking device 14, it is not limited to this. For example, you may comprise using a compression damper. In this case, as described above, the position of the damper 17 is reversed and placed on the take-out side. Moreover, you may comprise by a rotary damper and a rack-and-pinion. That is, the type and configuration of the damper are not particularly limited as long as it is a damper that generates an appropriate braking force when the washing tank 2 is taken out.

In addition, in this embodiment, although the structure which provides the projection part 15 in the washing tank 2 so that it may be latched by the lower part of the braking device 14 was demonstrated as an example, it is not limited to this. For example, the top and bottom of the braking device 14 shown in FIGS. 4 and 5 may be inverted, and it is good also as a structure which latches the protrusion part 15 from the upper side of the braking device 14. As shown in FIG. Thereby, the same effect is acquired.

In addition, although this embodiment demonstrated the example which comprised the braking device 14 and the protrusion part 15 in the side back part in the case 1, it is not limited to this. For example, it is good also as a structure provided in all the side surfaces in the case 1 . As a result, when a problem occurs in the braking device 14 , the user can adjust the problem in the braking device 14 from the front of the case 1 . The problem is, for example, when the receiving part 18 of the braking device 14 is moved from the original tilted position shown in FIG. 5 to the storage position shown in FIG. 4 with the washing tank 2 taken out, etc. The user himself can easily return to the original tilted position to solve the problem.

In addition, although this embodiment demonstrated the example which attaches the braking device 14 to either side of the left and right side of the case 1, it is not limited to this. For example, when a larger braking force is required, braking devices may be attached to both left and right sides.

In addition, although this embodiment demonstrated the example in which the braking device 14 was attached to the side surface of the case 1, and the protrusion part 15 was attached to the outer side of the side wall of the washing tank 2, it is not limited to this. For example, the braking device 14 may be attached to the side surface of the washing tank 2 , and the protrusion 15 may be attached to the inside of the side wall of the case 1 , and the same effect is obtained by the same operation.

(Embodiment 2)

Hereinafter, the structure of the dish washing machine in Embodiment 2 of this invention is demonstrated using FIG.6 and FIG.7.

Fig. 6 is a schematic cross-sectional side view of the dishwasher according to the second embodiment of the present invention. 7 is a schematic diagram showing the configuration of a braking device for a dishwasher according to the embodiment.

6 and 7 , the dishwasher of the present embodiment differs from the first embodiment in the configuration of the braking device. In addition, since the structure, operation|movement, and operation|action other than a braking device are the same as that of Embodiment 1, detailed description is abbreviate|omitted.

That is, the braking device 20 of the present embodiment is composed of a compression damper 20a having a damper rod 20b fixed to the inner wall of the case 1 in the longitudinal direction, for example. The damper rod 20b has a rotating shaft 20c at its distal end, and the rotating shaft 20c is provided with a roller 21 that rotatably contacts the contact surface 22 described below. In addition, the braking device 20 of the present embodiment is configured so as not to generate a braking force in the direction in which the damper rod 20b is drawn out.

The contact surface 22 is formed on the side wall of the washing tank 2 in a strip shape toward the rear from the door 9 side. The contact surface 22 is in contact with the outer peripheral surface of the roller 21 of the braking device 20 and moves the roller 21 in the vertical direction along with the movement of the cleaning tub 2 to reduce the braking force of the compression damper 20a. generate And the contact surface 22 is comprised from the door 9 side with the horizontal surface 22a, the inclined surface 22b, and the horizontal surface 22c. The horizontal surface 22a of the contact surface 22 is the position where the roller 21 comes into contact when the cleaning tank 2 shown in FIG. 6 is in the storage position in the case 1 (equivalent to the cleaning tank position in FIG. 1). It is formed horizontally at the lowest position in the vicinity of the position A. The inclined surface 22b of the contact surface 22 is inclined upward from the position B where the roller 21 comes into contact with the position C (corresponding to the cleaning tub position in Fig. 2) when the cleaning tub 2 is slightly pulled out (the damper). in the direction in which the rod 20b is to be compressed). Moreover, the inclined surface 22b corresponds to the area|region where the washing tank of FIG. 2 demonstrated in Embodiment 1 moves from the position B near the storage position to the predetermined position shown by the position C. As shown in FIG. Moreover, the horizontal surface 22c of the contact surface 22 is formed horizontally from the position B to the position D from which the washing tank 2 is completely taken out at the highest position. Moreover, the horizontal plane 22c corresponds to the position of the area|region to which the washing tank of FIG. 3 demonstrated in Embodiment 1 moves.

Then, when the washing tank 2 is taken out from the storage position, the braking device 20 generates a braking force such that the movement from the storage position (position A) to the predetermined position (position C) takes a predetermined time or longer. The magnitude of the braking force of the compression damper 20a is the same as in the first embodiment.

Next, the operation of the braking device 20 of the present embodiment will be specifically described with reference to FIGS. 6 and 7 .

6 and 7 , when the washing tank 2 is taken out from the storage position (position A), the contact surface 22 provided in the washing tank 2 moves in the take-out direction. At this time, the roller 21 of the braking device 20 moves while rotating on the horizontal surface 22a of the contact surface 22 . In addition, from the contact position A to the position B, the washing tank 2 starts to move and moves the horizontal surface 22a of the contact surface 22 . During this time, the roller 21 does not push the damper rod 20b into the compression damper 20a. Therefore, the braking force by the compression damper 20a is not generated. Thereby, an increase in the force when the user takes out the washing tank 2 at the first time requiring the greatest force does not occur. As a result, the user's feeling of use at the time of taking out the washing tank 2 is not impaired, and the taking out operation of the washing tank 2 can be performed without a feeling of incongruity.

And with taking out of the washing tank 2, the roller 21 moves the inclined surface 22b of the contact surface 22 of the position C from the position B. At this time, the compression damper 20a pushes the damper rod 20b by the roller 21 which rolls and moves on the contact surface 22 to generate a braking force. In addition, the generated braking force increases when the user tries to take out the washing tub 2 more vigorously because the damper rod 20b is pushed in more forcefully. On the other hand, when the damper rod 20b is taken out slowly, a large braking force is not generated.

Moreover, with the removal of the washing tank 2, the roller 21 moves the horizontal surface 22c of the contact surface 22 from the position C to the position D. At this time, the roller 21 does not push the damper rod 20b into the compression damper 20a. Therefore, the braking force by the compression damper 20a is not generated. In addition, the rotational resistance of the roller 21 in contact with the contact surface 22 is slight compared to the resistance due to the weight felt by the user when taking out the washing tub 2 . Therefore, problems such as a sense of incongruity do not arise for the user.

That is, the braking force of the compression damper 20a of the braking device 20 acts on the washing tub 2 only while the washing tub 2 is taken out from the position B to the position C. Conversely, when the removed washing tank 2 is pushed into the case 1 , the compression damper 20a follows the inclined surface 22b of the contact surface 22 and the damper rod 20b is drawn out from the compression damper 20a. . Therefore, the braking device 20 generates no braking force. In addition, the method of withdrawing the damper rod 20b may be a structure in which it withdraw|derives by the weight of the added compression spring (not shown) or the damper rod 20b and the roller 21. As shown in FIG. That is, as long as it is a structure in which the damper rod 20b is pulled out without generating a braking force, it will not specifically limit.

Moreover, although the structure in which the damper rod 20b and the contact surface 22 contact while rotating via the roller 21 was demonstrated as an example in this embodiment, it is not limited to this. For example, the tip of the damper rod 20b may be configured to slide on the contact surface 22 . In this case, it is preferable that the sliding resistance between the contact surface 22 and the damper rod 20b is less than or equal to a level that does not give a sense of discomfort to the user.

As described above, the dish washing machine of the present invention includes a case with an open front, a washing tub with an open top and a case freely installed in the front-rear direction in the case, and a washing tub provided on the front of the washing tub, and the washing tub is accommodated in the case It has a door which freely opens and closes the front surface of a case when it is in a position. In addition, a position detecting device for detecting that the washing tub is in the storage position, a washing device for washing dishes accommodated in the washing tub, and control of a series of washing operations of the washing device, as well as detecting the movement of the washing tub from the storage position It has a control device which stops the operation|movement of a washing|cleaning apparatus when a position detection device detects it. Moreover, you may have a braking device which generates the braking force which suppresses the take-out speed in at least a part from the storage position of the washing tank to a predetermined position.

According to this configuration, when the user tries to take out the washing tub during the washing operation, the braking device suppresses the taking out speed of the washing tub. And while the braking device is suppressing the ejection speed of the washing tank, the braking device completely stops the injection of the washing water. This prevents the sprayed washing water from jumping out of the case. As a result, it is possible to realize a highly reliable dishwasher that does not wet the periphery of the case or the user with the washing water.

In addition, the predetermined position of the dishwasher of the present invention may be a position where the washing water sprayed from the washing nozzle included in the washing device does not protrude out of the case. Thereby, the position of the washing tank from which the washing water does not protrude out of the case can be made clear. As a result, when the washing tank is taken out, a necessary braking force is applied, and the splashing of the washing water can be reliably prevented.

In addition, the braking device for a dishwasher of the present invention may generate a braking force such that when the washing tub is taken out from the storage position, it takes a predetermined time or more from the storage position to the predetermined position. Thereby, when the washing tank is taken out, a required braking force can be applied to suppress the take-out speed. As a result, splashing of the washing water from the washing tank can be reliably prevented.

In addition, the predetermined time of the dish washing machine of the present invention may be the time from when the position detecting device detects the movement of the washing tub until the injection of the washing water from the washing nozzle is stopped. Accordingly, it is possible to predict the stop time until the jetting stop of the washing water from the washing nozzle is predicted, and to apply a braking force required when the washing tank is taken out. As a result, the ejection speed of the washing tank can be suppressed, and the splashing of washing water can be reliably prevented.

In addition, the braking device of the dishwasher according to the present invention may change the braking force according to the speed at which the washing tub is taken out. Thereby, when taking out the washing tank slowly, the user does not need extra force. Moreover, it can suppress in advance that taking-out time becomes long meaninglessly. On the other hand, when the washing tank is vigorously taken out, the braking device generates a large braking force to control the movement of the washing tank beyond the stop time of the washing water. That is, the taking-out speed of the washing tank can be adjusted corresponding to the user's various usages. As a result, it is possible to prevent the washing water from splashing out of the device and to improve usability.

In addition, the braking device of the dishwasher according to the present invention may be controlled so that braking force is not generated at the initial stage of movement of the washing tub from the storage position. Thereby, an increase in the force when the user takes out the washing tank at the first time requiring the greatest force does not occur. As a result, it is possible to prevent the user's feeling of use from being damaged.

Further, in the dishwasher of the present invention, the braking device may be constituted by a damper. Thereby, electric energy is not consumed. In addition, when the user takes out the washing tub in a hurry, only the braking force may act on the movement of the washing tub. That is, since the cleaning device is not locked, it is possible to prevent the user from feeling embarrassed or uncomfortable.

In addition, the damper of the dishwasher of the present invention may generate a braking force only in the direction in which the washing tub is taken out. Thereby, when pushing in a washing tank, a user does not require extra force. As a result, the user can accommodate the cleaning device in the case without feeling uncomfortable.

Further, the door of the dishwasher of the present invention may be configured such that a handle and a decorative panel according to the design of the door of the system kitchen in which it is accommodated can be mounted. Thereby, it integrates with a system kitchen, and the design of a system kitchen improves.
