Description

Dish washing machine Field of invention

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

Japanese Patent Publication No. 2007-301065 (hereinafter referred to as Patent Document 1) discloses that the washing water to be sprayed is not washed out when the user wants to pull out the washing tank during the washing operation. The built-in type is a pull-out type dishwasher.

Hereinafter, a conventional dishwasher according to Patent Document 1 will be described with reference to Fig. 8 .

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

On the other hand, Fig. 8 shows a state in which the built-in dishwasher of the so-called pull-out type is housed in the system kitchen. Further, the portion shown by the chain line of Fig. 8 shows a state in which the washing tank is pulled out from the dishwasher body.

As shown in Fig. 8, the conventional dishwasher is constructed by at least a dishwasher body 101 opened at the front, a washing tank 102 provided in the dishwasher body 101, and a door portion 102a. The washing tank 102 has an opening at the upper side and is disposed in the front-rear direction (toward the dishwasher body 101) The direction of the opening is free to move. The door portion 102a is provided in front of the washing tank 102 and covers the front surface of the dishwasher body 101. The washing tank 102 is provided with a cutlery basket 104, a washing nozzle 105, and the like. The cutlery basket 104 puts and stores the washed dishes 103. The washing nozzle 105 sprays the washing water toward the tableware 103 placed on the dish basket 104 and washes it.

Further, a micro switch 106, a gear motor 107, and the like are disposed in the dishwasher body 101 behind the cleaning tank 102. The micro switch 106 detects the movement of the cleaning tank 102 in the front and rear directions. The gear motor 107 operates to restrain the movement of the washing tank 102 at the first restraint position and the second restraint position. When the gear motor 107 restrains the movement of the cleaning tank 102, the micro switch 106 detects that the cleaning tank 102 has moved from the first restraint position to the second restraint position, and does not take it within a predetermined time. The restraint of the cleaning tank 102 of the gear motor 107 is released.

According to this configuration, even if the user grasps the door handle 102b of the door portion 102a and wants to pull the cleaning tank 102, the cleaning tank 102 cannot be pulled out to the front of the second restraint position for at least a predetermined time. Thereby, it is possible to prevent the washing water sprayed from the washing nozzle 105 from flying outward from the washing tank 102 or being sprayed to the user.

Next, a conventional dishwasher for a different example disclosed in Japanese Laid-Open Patent Publication No. 2011-206130 (hereinafter referred to as Patent Document 2) will be described with reference to FIG.

Figure 9 is a side cross-sectional view showing the upper portion of the door of the conventional dishwasher of the different examples. 9 shows an outline of the door handle 113 for pulling the cleaning groove 111 and the door handle switch 115 for detecting the hand hanging on the door handle 113.

The dishwasher shown in FIG. 9 has a washing tank 111 that is movable in the front-rear direction and a door provided in front of the washing tank 111 in the same manner as the dish washing machine shown in FIG. 112 and so on. Further, the dishwasher includes a lock device (not shown), a door handle switch 115, and the like. The door portion 112 has a door handle 113, a door handle lever 114, and the like. The door handle 113 is provided at the upper portion of the door portion 112, and the user holds the door handle 113 and pulls the washing groove 111 out. The door handle lever 114 is provided to be freely rotatable inside the door handle 113. The locking device can lock the movement and unlocking in the front and rear directions toward the washing tub 111. The door handle switch 115 detects the rotation of the door handle lever 114.

Hereinafter, the operation of the above-described dishwasher will be specifically described.

First, the user wants to pull out the washing tank 111 and put the hand on the door handle 113. At this time, the door handle lever 114 is pressed upward and the shaft 114a is rotated only toward the center by the angle θ1. Thereby, a space for hanging the hand inside the door handle 113 is formed. That is, as long as the user does not rotate the door handle lever 114, it is impossible to form a space in which the hand can be hung inside the door handle 113. Therefore, the washing tank 111 cannot be pulled out toward the front.

Further, the door handle switch 115 detects the rotation of the door handle lever 114 at a point when the door-forming lever 114 is rotated only by an angle θ3 smaller than the angle θ1.

Next, when the door handle switch 115 detects the rotation of the door handle lever 114, the control device (not shown) releases the locking device. Further, the control device stops the operation of the cleaning pump that injects the washing water from the washing nozzle (not shown).

That is, in the above-described dishwasher, when the user hangs the hand on the door handle 113. When the door handle lever 114 is rotated by the angle θ3, the locking device is released. However, in order to pull out the washing tank 111, in order to rotate the door handle lever 114 to the angle θ1, it is necessary to apply the force again. Therefore, although it is not too much, it takes time to pull out the washing tank 111. During this time, the control device stops the cleaning of the pump and stops the injection of the washing water from the washing nozzle. Thereby, it is possible to prevent the washing water from flying out of the machine from the inside of the washing tank 111.

However, in the configuration of the dishwasher according to Patent Document 1, a gear motor, a solenoid valve, or the like is used as a method of locking the movement of the washing tank. At this time, when a power failure occurs during the operation of the dishwasher, the lock for preventing the movement of the washing tank cannot be released. Therefore, it is necessary to have some countermeasure against the lock of the movement of the washing tank in the event of a power failure. Moreover, the gear motor or solenoid valve that locks the movement of the washing tank consumes electric energy, and thus violates the trend of energy saving. Further, when the user has to urgently pull out the washing tank, when the washing tank is locked, there is a problem that the user may be confused or feel uncomfortable.

Further, in the configuration of the dishwasher according to Patent Document 2, by the user pushing the door handle lever, the lock of the lock device can be released and the cleaning tank can be pulled out. Further, while the door handle lever is moved from the angle θ3 to the angle θ1, the control device stops the operation of washing the pump. Thereby, the user can pull out the washing tank. However, there is a slight delay in the start of the operation of the washing pump until the injection of the washing water from the washing nozzle is completely stopped. At this time, when the speed at which the user pulls out the washing tank is delayed at the above time, there is no problem if it is slow. However, in an emergency state, when the user hangs the door handle and pulls it out of the washing tank, there is a washing water. The possibility that the injection did not stop completely. At this time, it is impossible to prevent the washing water from flying out of the washing tank.

In other words, in the configuration of the conventional dishwasher, it is possible to reliably prevent the washing water from the washing tank from flying out of the machine in accordance with various methods of use by the user.

In the cleaning operation of the present invention, when the user pulls out the washing tank, the drawing speed of the washing tank can be controlled. Thereby, a dishwasher can be provided which can prevent the sprayed washing water from flying out of the washing tank and spraying it around.

That is, the dishwasher of the present invention has a casing having an opening at the front, and a washing tank that is provided to be movable in the front-rear direction and disposed in the casing and having an upper opening; the door portion is disposed in front of the washing tank, and When the cleaning tank is located at the storage position in the casing, the front surface of the casing can be freely opened and closed; the position detecting device detects that the washing tank is located at the storage position; and the washing device cleans the tableware contained in the washing tank. And a control device that controls a series of cleaning operations of the cleaning device, and stops the operation of the cleaning device when the position detecting device detects that the cleaning groove moves from the storage position; and the braking device is from the foregoing At least a part of the storage position of the washing tank to the predetermined position causes a braking force that suppresses the drawing speed to occur.

According to this configuration, when the user wants to pull out the washing tank during the washing operation, the braking device can suppress the drawing speed of the washing tank. Moreover, the brake device suppresses the pulling speed of the washing tank, and the control device makes the washing water The spray stops completely. Thereby, it is possible to prevent the sprayed washing water from flying out of the casing. As a result, it is possible to realize a dishwasher which is excellent in reliability without being sprayed around the casing or the user by the washing water.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited by the embodiment.

(Embodiment 1)

Hereinafter, the dishwasher of the first embodiment of the present invention will be described with reference to Figs. 1 to 3 . In the present embodiment, the built-in type dishwasher in the pull-out type is stored in the system kitchen as an example, but it is needless to say that it is not limited thereto.

Fig. 1 is a side cross-sectional view showing a state in which a washing tank of the dishwasher of the first embodiment of the present invention is housed in a casing. Fig. 2 is a side cross-sectional view showing a state in which the washing tank of the dishwasher of the embodiment is pulled out from the casing to a predetermined position. Fig. 3 is a side cross-sectional view showing a state in which the washing tank of the dishwasher of the embodiment is pulled out from the casing and passed over a predetermined position. In the present embodiment, the position in which the washing tank shown in Fig. 1 is completely housed in the casing is described as a "storing position". Further, in FIGS. 1 to 3, the left direction in the drawing will be described as the drawing direction of the washing tank. The same is true in the following figures.

As shown in FIG. 1 to FIG. 3, the dishwasher according to the present embodiment includes a casing 1 which is formed in a box shape and has a front opening, and a washing tank 2 which is provided in the casing 1 so as to be movable in the front-rear direction and open on the upper surface. . Moreover, the dishwasher is housed in the system kitchen K.

The washing tank 2 is suspended from a guide rail 3 which is disposed horizontally inside the both side walls of the casing 1, and is configured to move in the front-rear direction with a small force. Thereby, the user can easily pull out the washing tank 2 to the outside of the casing 1, or push it into the casing 1. Furthermore, the washing tank 2 has a cutlery basket 5 in which the dishes 4 are arranged in a lined manner, and a washing device 6 that sprays and washes the washing water to the dishes 4. The washing device 6 is further composed of: washing water supplied to the washing tank 2 The circulating cleaning pump 7 is configured by a washing nozzle 8 that ejects the washing water pumped by the washing pump 7 to the tableware 4.

The door portion 9 is provided with a free switch in front of the washing tub 2, and covers the front surface of the casing 1 when the washing tub 2 is placed at a storage position that is pushed into and housed inside the casing 1. Further, the door portion 9 is fully equipped with a decorative panel 9a of the same style as the door panel or the drawer of the system kitchen K that houses the dishwasher. Further, the door portion 9 has a handle 9b. The handle 9b is used when the user grasps and pulls the washing tub 2 toward the outside of the casing 1, or pushes it into the casing 1. Moreover, the handle 9b is also constructed in the same manner as the door piece or drawer of the system kitchen K.

However, most of the door parts of the conventional dishwashers are provided with decorative panels of the same style as the door panels of the system kitchen, but in general, the styles of the handles will be different. Specifically, as described above, the conventional door portion has an operation lever or the like for unlocking the door handle lever or the like. Further, an operation switch, an operation lamp, and the like are disposed in the door portion.

However, in the dishwasher of the present embodiment, since the operation lever, the operation switch, the operation lamp, and the like are not disposed in the door portion, the pattern of the door portion 9 can be configured in the same manner as the system kitchen. As a result, it is only a glance, and it is difficult to determine that the dishwasher is stored in the system kitchen, and it is possible to have a uniform structure.

Moreover, the middle cover 10 is provided in the upper part of the inside of the casing 1, and the opening in the upper surface of the washing tank 2 is blocked. The middle cover 10 is provided with a mat 10b on a surface facing the opening of the washing tub 2, and is disposed to be vertically movable by a pair of right and left coupling mechanisms 10a including a pair of front and rear couplings. Further, the middle cover 10 is moved in the vertical direction by the connection mechanism 10a in accordance with the operation in the front-rear direction of the cleaning tank 2, for example, When the cleaning tank 2 is in the storage position, the upper opening is closed.

Moreover, the control device 11 is provided between the washing tank 2 and the door portion 9, and controls a series of washing operations such as a washing step, a flushing step, and a drying step of the dishwasher.

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

The position detecting device, that is, the micro switch 13 is provided inside the rear side of the casing 1 (on the side opposite to the door portion 9), and detects that the washing tub 2 is pulled out and moved from the storage position. The micro switch 13 is connected to the control device 11. Further, when the movement of the storage position from the cleaning tank 2 is detected by the micro switch 13, the control device 11 is controlled to stop the operation of the cleaning pump 7.

Moreover, the brake device 14 is provided, for example, on the inner side surface of the casing 1, and generates a braking force that suppresses the drawing speed of the washing tank 2. At this time, the side surface of the washing tank 2 is provided with a projection 15 that cooperates with the brake device 14.

Specifically, in the brake device 14, when the cleaning tank 2 is pulled out from the storage position, at least a part of the storage position to the predetermined position causes a braking force that suppresses the drawing speed of the cleaning tank 2. In addition, in the present embodiment, for example, a position at which the washing water sprayed from the washing nozzle 8 does not fly out of the casing 1 is regarded as a predetermined position. For specific locations, it will be described later. That is, as described above, when the predetermined position is set, the position of the washing tank 2 in which the washing water does not fly out of the casing 1 becomes clear. Thereby, for example, when the washing tank 2 is pulled out to the predetermined position, the braking force required by the brake device 14 acts on the washing tank 2. As a result, it is possible to reliably prevent the washing water from the washing tank 2 from flying out to the outside.

Hereinafter, the brake device of the dishwasher of the present embodiment will be described with reference to Figs. 4 and 5 .

4 and 5 are schematic views showing the internal structure of a brake device of the dishwasher of the same embodiment. 4 is a state in which the brake device in the state in which the washing tub shown in FIG. 1 is housed in the casing is shown. That is, the state of the brake device 14 when the cleaning tank 2 is in the storage position is displayed. Moreover, Fig. 5 is a view showing a state of the brake device in a state in which the washing tub shown in Fig. 2 is pulled out from the casing to a predetermined position.

As shown in FIGS. 4 and 5, the brake device 14 is constituted by a casing 16, a receiving portion 18 in which the shock absorber 17 is engaged with the projection 15 in the casing 16, and a spring 19 and the like. Further, the guide portion 16a that guides the movement of the receiving portion 18 is formed on the side surface of the casing 16.

The shock absorber 17 has a shock absorber pull rod 17a that enters and exits in the moving direction of the washing tank 2, and is configured as a tensile shock absorber that generates braking force only in one direction. That is, the shock absorber 17 generates a braking force when the shock absorber pull rod 17a is pulled out. On the other hand, when the shock absorber pull rod 17a is pushed in, the braking force is not generated.

The receiving portion 18 of the brake device 14 has the front end of the vibration stirer bar 17a as a rocking shaft 17b, and is attached to be freely rocked in parallel with the side surface of the casing 1. The receiving portion 18 has, for example, two guide pins 18a and 18b that are engaged with the guide portion 16a. Thereby, the receiving portion 18 is engaged with the guide portion 16a and moved along the guide portion 16a. Further, the receiving portion 18 has a recessed portion 18c that is recessed at the lower side, and the recessed portion 18c is configured to accommodate the protruding portion 15 provided in the cleaning tub 2.

The guide portion 16a has an opposite end portion 16c in which the shock absorber 17 is disposed The J-shape is curved laterally upward and formed on the side of the casing 16.

Further, the spring 19 of the brake device 14 is constituted by, for example, a tension spring. One end of the spring 19 is locked with the locking portion 16b provided in the housing 16. The other end of the spring 19 is locked above the rocking shaft 17b and the locking portion 18d provided in the receiving portion 18. At this time, the tension of the spring 19 acts on the locking portion 18d at all times, and also acts in the direction in which the shock absorber pull rod 17a is pushed. Thereby, the receiving portion 18 can prevent the vibration in the guide portion 16a. Further, the tension of the spring 19 acts to reduce or eliminate the resistance in the direction in which the braking force of the shock absorber 17 does not occur.

In other words, as shown in FIG. 4, the cleaning tank 2 is placed in the storage position, and the vibration absorber rod 17a is pushed into the vibration absorber 17. At this time, the protruding portion 15 is received in the recess 18c of the receiving portion 18.

On the other hand, as shown in FIG. 5, in a state in which the cleaning tank 2 is pulled out, the receiving portion 18 moves in the pull-out direction together with the protrusion portion 15. 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 pull-out side moves upward by the bending of the J-shaped guide portion 16a. Thereby, the receiving portion 18 is inclined, and the engagement between the protruding portion 15 provided in the cleaning tub 2 and the concave portion 18c is released. At this time, the spring 19 becomes an elongated state. However, the receiving portion 18 is in a state in which the curved end portions of the guide pin 18a and the guide portion 16a are locked by the rotational force received by the spring 19. Further, together with the receiving portion 18, the guide pin 18a is held in the above-described locked state.

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

Hereinafter, the operation and action of the dishwasher of the above configuration will be described.

First, the user grasps the handle 9b provided on the door portion 9 to pull out the washing tub 2. Next, the dishes 4 are placed in the cutlery basket 5 and the lotion is placed. Thereafter, the user selects the operation plan by using the plan selection button located in the operation unit 12, and presses the button for starting the operation.

Further, the cleaning tank 2 is pushed into the storage position in the casing 1. At this time, the middle cover 10 is moved rearward and downward by the connection mechanism 10a, and the opening of the washing tank 2 is closed. At the same time, the position detecting device, that is, the micro switch 13, is used to detect that the cleaning tank 2 is at the storage position. Further, 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 the water supply valve (not shown), and supplies the tap water of the washing water to the washing tank 2 to supply water. Further, the control device 11 performs control for energizing the heater (not shown) and heating the washing water to drive the cleaning pump 7 and the like. Thereby, the dishwashing machine performs a series of washing operations for washing the dishes 4 accommodated in the washing tank 2.

As described above, the dish washing mechanism of the present embodiment causes the user to allow the tableware 4 to enter or exit during the cleaning operation. At this time, the user grasps the handle 9b provided in the door portion 9 of the washing tub 2 during the washing operation, and pulls out the washing tub 2.

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

First, when the cleaning tank 2 is pulled out during the washing operation, the micro switch 13 detects the movement of the washing tank 2 from the storage position. And, in the course of the washing step or the flushing step of spraying the washing water, the control device 11 stands Stop the power supply to the cleaning pump 7. At this time, the washing pump 7 will pressurize the washing water toward the washing nozzle 8. Therefore, even if the energization to the cleaning pump 7 is stopped, the discharge of the washing water from the washing nozzle 8 does not immediately stop due to the residual pressure or the inertial force. That is, the power supply from the cleaning pump 7 is stopped, and although it is a short time, after a certain period of time, the washing water is sprayed from the washing nozzle 8 to be completely stopped.

At this time, normally, the opening on the upper surface of the washing tank 2 is closed by the middle cover 10. Therefore, at the initial stage of pulling out the washing tank 2, even if the middle cover 10 is moved upward, the washing tank 2 can be sealed by the elasticity of the mat 10b. That is, the washing water does not leak during the sealing action of the mat 10b.

Moreover, as shown in FIG. 2, at least when the front end of the washing tank 2 is not pulled out to the front of the front end of the casing 1, the washing water sprayed from the washing nozzle 8 does not fly out of the casing 1. .

On the other hand, in the present embodiment, as described above, the position at which the tip end of the cleaning tank 2 is pulled out to the front end of the casing 1 is regarded as a predetermined position. Thereby, the predetermined position is made clear as the position of the washing tank 2 in which the washing water does not fly out of the casing 1.

Therefore, in the present embodiment, as shown in the following, the washing water is prevented from flying out based on the moving time of the washing tub 2 up to the predetermined position.

First, the micro switch 13 detects that the time from the start of the movement of the washing tank 2 pulled out by the user to the stop of the discharge of the washing water from the washing nozzle 8 is regarded as the stop time. Further, the movement time until the cleaning tank 2 is pulled out to the predetermined position is regarded as the pull-out time. And use the brake device to control the cleaning The pull-out time of the tank 2 is such that the stop time is the same as the pull-out time or the pull-out time is longer than the stop time. Thereby, it is possible to prevent the washing water from flying out of the casing 1 in advance.

That is, the brake device 14 of the washing tank 2 controls the above-described pull-out time by the braking force of the vibration absorber 17. Specifically, when the cleaning device 2 is pulled out from the storage position, the brake device 14 generates a braking force and controls the pulling-out time of the cleaning tub 2 to take a predetermined time or more from the storage position to the predetermined position.

Next, the operation of the brake 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 tank 2 is pulled out from the storage position A, the protrusion 15 provided in the washing tank 2 moves in the pull-out direction. Further, the projection portion 15 to be described later moves from the storage position A to the position B where the concave portion 18c of the receiving portion 18 abuts, and then the receiving portion 18 is stretched and moved toward the projection portion 15. Further, the shock absorber 17 pulls the shock absorber pull rod 17a by the concave portion 18c that moves together with the receiving portion 18 to generate a braking force. However, the generated braking force becomes larger as the user pulls the cleaning tank 2 harder. On the other hand, when the shock absorber pull rod 17a is pulled out gently, a large braking force is not generated.

At this time, in the present embodiment, as shown in FIG. 4, the width W1 of the concave portion 18c of the receiving portion 18 is made larger than the width W2 of the protruding portion 15. Thereby, when the operation from the storage position A to the position B is started, the protruding portion 15 does not move the receiving portion 18. Therefore, the braking force of the shock absorber 17 does not occur. Thereby, in the initial stage where the maximum force is required, there is no increase in the force when the user pulls out the washing tank 2. As a result, the user of the cleaning tank 2 is not damaged. With the sense of use, the washing tank 2 can be pulled out without any sensation.

Further, as shown in FIG. 5, when the receiving portion 18 reaches the drawing-side end of the guiding portion 16a together with the movement of the projection 15, the curved shape of the J-shaped guide portion 16a is fitted and the receiving portion 18 is inclined. Thereby, the engagement of the recessed portion 18c and the projection portion 15 is released. Further, after the engagement is released, the cleaning tank 2 has no relationship with the brake device 14, and is smoothly pulled out along the guide rails 3 shown in Figs. At this time, the receiving portion 18 is maintained in the inclined state shown in FIG. 5 by the tension of the spring 19.

Brake device 14 will operate as explained above.

That is, the cleaning tank 2 is moved from the position B shown in FIG. 4 to the predetermined position C shown in FIG. 5, and the braking force of the shock absorber 17 of the brake device 14 acts on the cleaning tank 2 during the pulling out. Moreover, after the predetermined position C, even if the washing tank 2 is pulled out, the brake device 14 does not function at all.

On the other hand, when the cleaning tank 2 is pushed into the casing 1, the projections 15 of the washing tub 2 are accommodated in the recess 18c of the receiving portion 18 held in an inclined state during the drawing. Further, the receiving portion 18 that abuts against the protruding portion 15 returns to the storage position simultaneously with the cleaning tank 2. At this time, as described above, the shock absorber 17 generates a braking force, and the tension of the spring 19 acts on the receiving portion 18.

On the other hand, the braking force of the shock absorber 17 is set to be the same as the stop time of the washing water, the same as the drawing time of the washing tank 2, or the pulling time is longer than the stopping time.

Further, in general, the stop time of the micro switch 13 from the start of the detection to the stop of the discharge of the washing water from the washing nozzle 8 is, for example, about 0.4 second. And from The predetermined size of the storage position of the washing tank 2 to the predetermined position of the washing tank 2 shown in Fig. 2 is, for example, 30 mm. Therefore, in the present embodiment, the predetermined time until the cleaning tank 2 is pulled out from the storage position to the predetermined position is 0.5 second. However, the predetermined time is not limited to this, and may be arbitrarily set as long as it is equal to or longer than the discharge stop time of the washing water. Thereby, the stop time until the discharge of the washing water from the washing nozzle 8 is stopped can be predicted, and when the washing tank 2 is pulled out, the required braking force acts. As a result, it is possible to surely prevent the washing water from flying out of the washing tank 2.

Here, in JIS S1200:2012, the average moving distance of the pull-out switch recommended by the durability test of the pull-out of the storage unit is 0.25 ± 0.1 m per one second. That is, the average speed of the pull-out switch is 0.15 m/s to 0.35 m/s. Further, the average time for moving the predetermined size by 30 mm is 0.2 second to 0.09 second.

However, when the user pulls out the washing tank 2 of the dishwasher, the weight of the washing tank 2 is greater than the weight of the drawer of the storage unit, and the tension of the spring 19 of the brake device 14 occurs. Therefore, the actual dishwashing opportunity is provided with a pull-in device of a drawer (not shown). Therefore, when the washing tank 2 of the dishwasher is actually pulled out, the pull-out resistance is further increased compared to the storage unit of the JIS. Therefore, in reality, the pulling time of the washing tank 2 is slightly longer. Therefore, in the present embodiment, the predetermined time for the cleaning tank 2 to reach the predetermined position from the storage position is 0.5 second or longer regardless of the drawing speed. Further, the braking force of the brake device 14 is set so as to be as close as possible to the predetermined time. On the other hand, the braking force of the brake device 14 becomes larger as the speed of the cleaning tank 2 is pulled out according to the speed change, and the slower the smaller the speed. Thereby, the pulling speed of the washing tank 2 When the degree is slow, the braking force is made small to suppress the situation in which the pull-out time is indefinitely extended.

As described above, the dishwasher of the present embodiment has the brake device 14 that generates the braking force that suppresses the pull-out speed from at least a part of the storage position to the predetermined position when the cleaning tank 2 is pulled out from the storage position. Further, when the user wants to pull out the washing tank 2 during the washing operation, the brake device 14 suppresses the drawing speed of the washing tank 2. Thereby, the washing tank 2 can completely stop the injection of the washing water while being pulled out to the predetermined position. As a result, the washing water sprayed from the washing nozzle can be prevented from flying out of the casing 1, and the washing water can be prevented from being wetted.

Moreover, the brake device 14 is configured by the shock absorber 17 for the dishwasher of the present embodiment. Thereby, energy saving can be improved without consuming electric energy. Further, when the user wants to urgently pull out the washing tank 2, the brake device 14 acts only on the movement of the washing tank 2 to cause the braking force, and does not lock the movement of the washing tank 2. Therefore, there is no confusion or discomfort of the user who is locked by the washing tank 2 or the like. Further, the vibration damper 17 of the brake device 14 generates the braking force only in the direction in which the cleaning tank 2 is pulled out. Therefore, when the washing tank 2 is pushed into and stored in the casing 1, the user does not need to apply extra force. Thereby, the washing tank 2 can be smoothly stored.

Further, the dishwashing machine of the present embodiment changes the braking force generated by the brake device 14 in accordance with the drawing speed of the washing tub 2. Therefore, when the cleaning tank 2 is gently pulled out, since the generation of the braking force can be suppressed, the user does not need to apply extra force. Thereby, it is possible to suppress the situation in which the drawing time of the washing tank 2 is insignificantly extended. Conversely, when the cleaning tank 2 is pulled out forcefully, the brake is applied. The device 14 is adjusted such that a large braking force is generated and the pull-out time of the washing tank 2 becomes a predetermined time or longer. In other words, the pull-out speed is adjusted in accordance with various usage modes of the user to prevent the washing water from flying out of the casing 1. Thereby, it is possible for the user to provide a dishwasher that has an increased degree of free use.

Further, the dishwasher of the present embodiment can be configured such that the decorative panel of the door portion 9 and the handle are matched with the pattern of the door panel of the system kitchen. That is, in the conventional dishwasher, the decorative panel portion is matched with the pattern of the door panel of the system kitchen, but in terms of the handle, it is constructed by the dishwasher itself. However, the door portion 9 of the present embodiment does not need to have a function of the handle. Therefore, the decorative panel 9a of the door portion 9 and the handle 9b can be combined with the pattern of the system kitchen door panel. Thereby, it can be constructed by integrating with the system kitchen. As a result, the design of the system kitchen can be improved.

In the present embodiment, the brake device 14 has been described as an example in which the position of the vibration absorber 17 with respect to the guide portion 16a is provided on the side opposite to the direction in which the cleaning tank 2 is pulled out. However, the present invention is not limited thereto. For example, the position of the shock absorber 17 may be the pull-out direction side, or the upper side or the lower side. Further, the shock absorber 17 can be disposed obliquely. As a result, the degree of freedom in design will increase.

Further, in the present embodiment, the vibration absorber 17 as the brake device 14 has been described using an example in which the shock absorber is constructed, but the invention is not limited thereto. For example, it can be constructed using a compression shock absorber. At this time, as described above, the position of the shock absorber 17 is reversed and placed on the drawing side. Further, it can be configured by a rotary vibration absorber, a rack and a pinion. In other words, the type of the shock absorber that generates the appropriate braking force when the cleaning tank 2 is pulled out Or the composition is not particularly limited.

Further, in the present embodiment, the configuration in which the protrusion portion 15 is provided in the cleaning tank 2 and the lower portion of the brake device 14 is locked is described as an example, but the invention is not limited thereto. For example, the brake device 14 shown in Figs. 4 and 5 can be reversed upside down, and the projection 15 can be locked by the upper side of the brake device 14. Thereby, the same effect can be obtained.

Further, in the present embodiment, an example in which the brake device 14 and the projection portion 15 are formed in the rear portion of the inner side surface of the casing 1 has been described, but the invention is not limited thereto. For example, it can be configured in the front portion of the side surface of the casing 1. Thereby, when a malfunction occurs in the brake device 14, the user can adjust the malfunction of the brake device 14 from the front surface of the casing 1. In the state in which the cleaning device 2 is pulled out, the receiving portion 18 of the brake device 14 is changed from the originally inclined position shown in FIG. 5 to the storage position shown in FIG. 4, and the like. The location itself allows the user to easily reply and resolve the bad situation.

Further, in the present embodiment, an example in which the brake device 14 is attached to either side of the left and right sides of the casing 1 has been described, but the invention is not limited thereto. For example, when a larger braking force is required, a brake device can be mounted on both the left and right sides.

Further, in the present embodiment, an example in which the brake device 14 is attached to the side surface of the casing 1 and the projection portion 15 is attached to the outside of the side wall of the cleaning tank 2 has been described, but the invention is not limited thereto. For example, the brake device 14 can be attached to the side surface of the cleaning tank 2, and the protrusion 15 can be attached to the inside of the side wall of the casing 1. The same effect can be obtained by the same operation.

(Embodiment 2)

Hereinafter, the dish washing mechanism according to the second embodiment of the present invention This will be described using FIG. 6 and FIG. 7.

Figure 6 is a side cross-sectional view showing the dishwasher of the second embodiment of the present invention.

Fig. 7 is a schematic view showing the configuration of a brake device of the dishwasher according to the embodiment.

As shown in Fig. 6 and Fig. 7, in the dishwasher of the embodiment, the configuration of the brake device is different from that of the first embodiment. The configuration, operation, and operation of the brake device are the same as those of the first embodiment, and thus detailed description thereof will be omitted.

That is, the brake device 20 of the present embodiment is constituted by a compression shock absorber 20a having a vibration-damping rod 20b fixed in the longitudinal direction on the inner side wall of the casing 1. The damper rod 20b has a rotating shaft 20c at the tip end, and the rotating shaft 20c has a roller 21 that is rotatably abutted against the abutting surface 22 described below. However, the brake device 20 of the present embodiment is configured such that the brake lever 20b does not generate a braking force in the pull-out direction.

The abutting surface 22 is formed in a strip shape on the side wall of the washing tank 2 from the side of the door portion 9 toward the rear. The abutting surface 22 abuts against the outer peripheral surface of the roller 21 of the brake device 20, and together with the movement of the washing tub 2, the roller 21 is moved in the vertical direction and the braking force of the compression shock absorber 20a is generated. Further, the abutting surface 22 is constituted by a horizontal surface 22a, an inclined surface 22b, and a horizontal surface 22c from the side of the door portion 9. The horizontal surface 22a of the abutting surface 22 is horizontally formed in the vicinity of the position A where the roller 21 abuts when the cleaning tank 2 shown in Fig. 6 is located at the storage position in the casing 1 (the same position as the washing tank of Fig. 1). At the lowest position. When the inclined surface 22b of the abutting surface 22 is slightly pulled out of the washing tank 2, the roller 21 is from the abutting position B to the position C (with the washing tank of Fig. 2). The position is slanted upward (the direction in which the shock absorber rod 20b is compressed). On the other hand, the inclined surface 22b corresponds to the region in which the cleaning groove in FIG. 2 described in the first embodiment moves from the position B near the storage position to the predetermined position indicated by the position C. Further, the horizontal plane 22c of the abutting surface 22 is formed at the highest position from the position B to the position D at which the washing tank 2 is completely pulled out. On the other hand, the horizontal plane 22c corresponds to the position of the region in which the washing tank moves in Fig. 3 described in the first embodiment.

Further, the brake device 20 generates a braking force to move from the storage position (position A) to the predetermined position (position C) when the cleaning tank 2 is pulled out from the storage position, and it takes a predetermined time or longer. The magnitude of the braking force of the compression shock absorber 20a is the same as that of the first embodiment.

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

As shown in FIG. 6 and FIG. 7, when the cleaning tank 2 is pulled out from the storage position (position A), the contact surface 22 provided in the washing tank 2 moves in the pull-out direction. At this time, the roller 21 of the brake device 20 is rotated on the horizontal surface 22a of the abutting surface 22 and moved. On the other hand, from the contact position A to the position B, the horizontal plane 22a of the abutting surface 22 is moved when the operation of the washing tank 2 is started. During this period, the roller 21 does not push the shock absorber pull rod 20b into the compression shock absorber 20a. Therefore, the braking force of the compression shock absorber 20a does not occur. Thereby, there is no increase in the force when the user pulls out the washing tank 2 in the initial period when the maximum force is required. As a result, when the cleaning tank 2 is pulled out, the user's feeling of use can be prevented, and the operation washing tank 2 can be pulled out without any sense of discomfort.

And, together with the pulling out of the washing tank 2, the roller 21 will move from the position B It moves on the inclined surface 22b of the abutting surface 22 of the position C. At this time, the compression shock absorber 20a generates a braking force that is pushed into the vibration stirer bar 20b by the roller 21 that is rotated and moved on the abutting surface 22. However, the generated braking force becomes larger as the user pulls the cleaning groove 2 harder as the user pulls the shock absorber lever 20b harder. On the other hand, when the shock absorber pull rod 20b is pulled out gently, a large braking force is not generated.

Further, together with the drawing of the cleaning tank 2, the roller 21 is moved on the horizontal surface 22c of the abutting surface 22 from the position C position D. At this time, the roller 21 does not push the shock absorber pull rod 20b into the compression shock absorber 20a. Therefore, the braking force of the compression shock absorber 20a does not occur. On the other hand, the rotational resistance of the roller 21 against which the abutting surface 22 abuts is slightly lower than the resistance of the weight felt when the user pulls out the washing tub 2. Therefore, there is no problem such as a sense of violation for the user.

That is, the braking force of the compression shock absorber 20a of the brake device 20 acts on the cleaning tank 2 only while the cleaning tank 2 is pulled out from the position B to the position C. On the contrary, when the pulled cleaning tank 2 is pushed into the casing 1, the compression shock absorber 20a pulls the shock absorber rod 20b from the compression shock absorber 20a along the inclined surface 22b of the abutting surface 22. . Therefore, the brake device 20 does not cause the braking force to be generated. Further, the method of pulling out the shock absorber pull rod 20b may be a configuration in which the compression spring (not shown) or the weight of the shock absorber pull rod 20b and the roller 21 is pulled out. In other words, the configuration in which the shock absorber pull rod 20b is pulled out is not particularly limited as long as the braking force is not generated.

In the present embodiment, the configuration in which the vibrator rod 20b and the abutting surface 22 are rotated and abutted by the roller 21 is described as an example, but the invention is not limited thereto. For example, the front end of the shock absorber pull rod 20b can be configured such that the abutment surface 22 slide. At this time, the sliding resistance of the abutting surface 22 and the shock absorber tie rod 20b is preferably not less than the degree of discomfort given to the user.

As described above, the dishwasher of the present invention has a casing that is open at the front, a washing tank that is provided in the casing so as to be movable in the front-rear direction and that is open on the upper surface, and a washing tank provided in front of the washing tank in the casing. When accommodating the position, the front side of the casing is covered with a door portion of a free switch. Moreover, the detection device for detecting the position of the cleaning tank at the storage position, the washing device for washing the dishes stored in the washing tank, and the cleaning operation of one of the cleaning devices are detected, and the detecting device detects that the washing tank is moved from the storage position. In this case, the control device for stopping the operation of the cleaning device is stopped. Further, it is possible to provide a brake device that generates a braking force that suppresses the pulling speed at least a part of the storage position from the cleaning tank to a predetermined position.

According to this configuration, when the user wants to pull out the washing tank during the washing operation, the pulling speed of the washing tank can be suppressed by the brake device. Further, while the brake device suppresses the drawing speed of the washing tank, the brake device completely stops the injection of the washing water. Thereby, it is possible to prevent the sprayed washing water from flying out of the casing. As a result, it is possible to realize a dishwasher which is excellent in reliability without being sprayed around the casing or the user by the washing water.

Moreover, 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 fly out of the casing. Thereby, the position of the washing tank which determines that the washing water does not fly out of the casing can be understood. As a result, when the cleaning tank is pulled out, the required braking force acts, and the washing water can be surely prevented from flying out.

Moreover, the brake device of the dishwasher of the present invention is only washed. When the groove is pulled out from the storage position, the braking force is generated and it takes a predetermined time or more from the storage position to the predetermined position. Thereby, when the cleaning tank is pulled out, the required braking force can be acted upon and the pulling speed can be suppressed. As a result, it is possible to reliably prevent the washing water from the washing tank from flying out.

Moreover, the predetermined time of the dishwasher of the present invention may be any time from when the position detecting device detects the movement of the washing tank to the stop of the washing of the washing water from the washing nozzle. Thereby, it is possible to predict the stop time until the discharge of the washing water from the washing nozzle is stopped, and to apply the required braking force when the washing tank is pulled out. As a result, the drawing speed of the washing tank can be suppressed, and the washing water can be surely prevented from flying out.

Further, the brake device of the dishwasher of the present invention can change the braking force in accordance with the speed at which the washing tank is pulled out. Thereby, the user does not need extra force when pulling the washing tank gently. Further, it is possible to suppress the meaning of the pull-out time in advance without any sense. On the other hand, when the cleaning tank is pulled out forcefully, the braking device generates a large braking force, and the movement of the washing tank is controlled to be longer than the stopping time of the washing water. That is, the pull-out speed of the washing tank can be adjusted corresponding to the various usage modes of the user. As a result, the washing water can be prevented from flying out of the machine, and the degree of free use can be improved.

Moreover, the brake device of the dishwasher of the present invention can be controlled such that the braking force is not generated when the operation of the storage position of the washing tub is started. Thereby, in the initial stage where the maximum force is required, the increase in the force when the user pulls out the washing tank does not occur. As a result, it is possible to prevent damage to the user's feeling of use.

Moreover, the dishwasher of the present invention can utilize the shock device for the brake device The device is composed. In this way, no power is consumed. Further, when the user pulls out the washing tank urgently, only the braking force acts on the movement of the washing tank. That is, since the washing device is not locked, it is possible to prevent the user from being confused or unpleasant.

Further, the vibration absorber of the dishwasher of the present invention may be generated only by the direction in which the cleaning tank is pulled out. Thereby, the user does not need extra strength when pushing into the washing tank. As a result, the user can store the cleaning device in the casing without any sensation.

Further, the door portion of the dishwasher of the present invention can be constructed by attaching a handle and a decorative panel to the style of the stored kitchen door panel. In this way, the integration of the system kitchen, the design of the system kitchen will be improved.
