Description

Dishwasher}

The present invention relates to a dishwasher, and more particularly, to a dishwasher having a rack with improved user convenience.

In general, a dishwasher is a household appliance that cleans food wastes on the surface of dishes by high-pressure washing water sprayed from a spray nozzle.

A conventional dishwasher consists of a tub in which a washing tank is formed, and a summ installed on the bottom of the tub to store washing water. Here, by the pumping action of the washing pump mounted inside the sump, the washing water is moved to the spray nozzle, and the washing water moved to the spray nozzle is sprayed at high pressure through a spray hole formed at the end of the spray nozzle. In addition, the washing water sprayed at the high pressure hits the surface of the dish, so that dirt such as food waste from the dish falls to the bottom of the tub.

When storing dishes such as wine glasses or plates in the rack, a structure to hold the dishes is required, but when dishes such as wine glasses or plates are not stored, space is provided to accommodate more or more convenient storage of other types of dishes. It needs to be used efficiently.

The present invention provides a dishwasher that provides a structure capable of storing corresponding dishes when washing dishes such as wine glasses or plates, and storing a lot of other dishes when dishes such as wine glasses or plates are not washed. will be.

In addition, the present invention provides a dishwasher capable of conveniently storing dishes in a rack when dishes such as wine glasses or dishes are not washed.

In addition, the present invention provides a dishwasher that is convenient for storing dishes because a user does not have to bend his or her waist to store dishes in a lower rack.

The present invention provides a dishwasher capable of changing a structure in which dishes can be accommodated without putting a hand inside the rack.

In addition, the present invention provides a dishwasher capable of providing convenience to a user by rotating a wire structure capable of standing and storing dishes in a single motion that the user presses.

In addition, the invention can move two wire structures in the case of manipulating one manipulation unit, so that a user's operation can be simplified.

The present invention provides a dishwasher that includes two racks of different heights, each of which is of varying height and can be arranged to change positions with each other.

In the present invention, the upper rack loads and cleans a bowl of a small size, and the lower rack loads a bowl of a large size, and the sizes of the spaces for storing the bowls are different. Meanwhile, while the rack is rotated, the height of the rack is changed while maintaining a space of a different size. At this time, water can be supplied to the cleaning nozzle and thus cleaning is possible.

According to the present invention, it is possible to store a large amount of tableware in a form different from general tableware such as wine glasses and plates. In addition, when tableware such as wine glasses or plates is not stored, the internal structure of the rack can be changed to accommodate more other dishes.

In addition, it is difficult to perform a complicated operation while the user is holding the tableware, but it is possible to provide an environment in which a wire structure can be erected by a simple operation such as pressing the tableware. The wire structure can be rotated even if the user does not apply the force required to rotate the wire structure. That is, the wire structure can be rotated with a small force.

In addition, according to the present invention, when tableware such as wine glasses or plates is not stored, the bottom of the rack can be flattened so that the user can conveniently store general tableware in the rack.

In addition, since two structures necessary for storing dishes such as dishes can be changed with one operation, the user can conveniently use it.

In addition, when moving the lower rack to the upper side, the user does not need to hold the lower rack, so there is no need to bow the waist. Therefore, the user's discomfort may be improved by not performing an excessively heavy action on the user's waist.

In addition, according to the present invention, it is possible to wash dishes even when the position of the rack is changed.

3 is a control block diagram according to an embodiment.

In one embodiment, a sensing unit 900 for sensing that a user moves a rack located at an upper side of the first rack 100 and the second rack 200 is included. When a specific change is detected after moving the upper rack, the sensing unit 900 transmits to the controller 1000 that a related signal has occurred. In order to change the height of the rack located on the upper side, the sensing unit 900 may detect a force applied to the rack accordingly when an action of pressing the rack occurs.

The controller 1000 drives the driving motor 630 when the sensing unit 900 detects a signal set as a signal for which the user wants to change the height of the rack. When the driving motor 630 is driven, a rotational force is generated by the driving motor 630, and the guide unit 300 may rotate while the horizontal driving unit 600 is horizontally moved.

4 and 5 are diagrams illustrating a process in which two racks exchange positions.

In FIG. 4, the first rack 100 is disposed on the upper side, and the second rack 200 is disposed on the lower side. On the other hand, in FIG. 5, the second rack 200 is disposed on the upper side, and the first rack 100 is disposed on the lower side.

4 illustrates a process in which the first rack 100 and the second rack 200 change positions with each other in a state in which the first rack 100 is disposed on the upper side.

Through the process of FIGS. 4A to 4I, the first rack 100 may be moved downward and the second rack 200 may be moved upward.

After the user pulls out the first rack 100 forward without changing the height as shown in FIG. 4A, the first rack 100 may be pressed downward to apply a force to the first rack 100.

At this time, the sensing unit 900 senses the force applied by the user to the first rack 100 and transmits the detected force to the control unit 1000. The control unit 1000 drives the driving motor 630 to provide a force for horizontal movement of the horizontal driving unit 600.

The first protrusion 320 comes out forward from the first horizontal groove 422. Since the moving trajectory of the first protrusion 320 is guided by the first horizontal groove 422, the movement of the guide part 300 follows a predetermined trajectory. At the same time, the second protrusion 340 is moved upward along the second vertical groove 444. At this time, since the second vertical groove 444 is formed to be convex toward the rear (corresponding to the right side based on FIG. 4), the second protrusion 340 is moved while having a convex trajectory toward the rear.

Although the first protrusion 320 is deviated from the first guide groove 420, the second protrusion 340 is inserted into the second guide groove 440 and the movement trajectory is constrained. The movement of the guide part 400 follows a predetermined trajectory. In addition, the guide rotation center 310 of the guide part 400 is coupled to the horizontal driving part 600, and the horizontal driving part 600 cannot be moved in a vertical direction and can only be moved in a horizontal direction. . Accordingly, the guide part 400 is constrained at two points, so that the movement trajectory may be constant.

Since the driving motor 630 continuously provides rotational force, as the horizontal driving unit 600 moves, the cover member 610 coupled to the horizontal driving unit 400 is moved in the horizontal direction. According to FIG. 4G, when the second protrusion 340 moves out of the second vertical groove 444 and moves to the second horizontal groove 442, the first protrusion 320 is moved to the first horizontal groove 442. ) Again.

Therefore, when the second rack 200 is positioned below, the user does not need to bend the waist in order to store dishes in the second rack 200. That is, the user can store dishes by moving the second rack 200 upward. At this time, since the second rack 200 is moved upward, the first rack 100 is moved downward.

Even if the second rack 200 moves upward, the distance between the bottom of the second rack 200 and the ceiling of the main body 20 can be maintained enough to accommodate dishes, so that the second rack 200 In comparison with the first rack 100, a relatively large tableware may be stored.

5 illustrates a process in which the first rack 100 and the second rack 200 change positions with each other in a state in which the second rack 200 is disposed on the upper side.

The process according to FIG. 5 differs from the process according to FIG. 4, since there is only a difference in that the second rack 200 is disposed on the upper side, the contents described in FIG. 4 can be applied mutatis mutandis. , Repeated description is omitted.

While either of the first rack 100 and the second rack 200 is moved forward and moved downward, each rack is moved while forming a trajectory close to an ellipse rather than a circular shape. The first rack 100 and the second rack 200 are moved rearward and have a shorter movement distance in the longitudinal direction of the front and rear compared to the trajectory of the front while ascending.

Since the first rack 100 and the second rack 200 move together, interference does not occur while the first rack 100 and the second rack 200 are moved.

The wine holder operation unit 112 and the dish holder operation unit 122 may be alternately disposed on the front of the rack 100.

The wine holder operation unit 112 is disposed on the leftmost side with respect to the front of the rack 100, and after two plate holder operation units 122 are disposed in succession, the wine holder operation unit 112 may be disposed. have. Since the wine holder wire 143 has a larger radius of rotation than the dish fixing wire, it is preferable to be disposed at the edge of the rack 100 rather than at the center.

15 is a state in which the operation unit is not pressed as in Fig. 14A, so that the second wire assembly is disposed to overlap the first wire assembly, and Fig. 16 is a state in which the operation unit is pressed as in Fig. 14B, so that the second wire assembly is It is in a state that is vertically disposed on the first wire assembly.

15 and 16, a gear 114a is provided on the rotation shaft of the wine holder wire 143, so that when the wine holder wire 143 is rotated, the gear 114a is rotated together. The wine holder operation unit 112 includes a first push bar 113 connected to one end of a contact portion pressed by a user, a first locking bar 115 pressed by the first push bar 113 and the first locking bar It includes a first spring 116 that provides a restoring force to return to its original position when the force on 115 is removed.

The first push bar 113 is pushed rearward based on the drawings of FIGS. 15 and 16 when the wine holder operation part 112 is pressed by the user. In this case, the first push bar 113 may be rotated in a counterclockwise direction based on a rotation axis disposed in the center. The first push bar 113 has a curved shape rather than a straight line, so that one end is disposed at a position biased toward one side of the rack rather than at a central position of the wine holder operation unit 112. One end of the first locking bar 115 is coupled to the first spring 116. When the wine holder operation part 112 is pressed, the first push bar 113 is moved backward, and the first spring 116 is compressed as the first locking bar 115 rotates counterclockwise. . At this time, when the pressing force of the wine holder operation unit 112 is removed, the compressed first spring 116 is returned to its original shape, and the wine holder operation unit 112 may return to a non-pressed position.

One end of the first locking bar 115 may have a tapered shape and may have a relatively thin thickness toward the end. The first locking bar 115 may have a shape that is bent a plurality of times and may extend in various directions. The gears 114a installed on the rotating shaft of the wine holder wire 143 are coupled to mesh with a plurality of gears 114b and 114c. If any one of the three gears rotates, the other gears can also engage and rotate. The gear 114c located at the far end is provided with a spring 114e, so that when the external force applied to the gear is removed, the gear 114c may return to the initial position. The spring 114e is applicable to any component surface capable of providing a restoring force within a range that does not change the surface of the gear 114c in contact with another gear. A groove 114d into which one end of the first locking bar 115 can be inserted is formed on the outer peripheral surface of the gear 114c. When one end of the first locking bar 115 is inserted into the groove 114d, the gear 114c is not rotated and is constrained. On the other hand, when one end of the first locking bar 115 comes out of the groove 114d, the first locking bar 115 cannot restrain the gear 114c, and is caused by the restoring force of the spring 114e. The gear 114c is rotated. As the gear 114a is rotated by the rotational force generated at this time, the first wine holder wire 143 is rotated in a counterclockwise direction, so that it may be moved to a second position. Then, when the user rotates the wine holder wire 143 in the clockwise direction, the spring 114e is twisted due to the rotational force applied by the gear 114a, thereby forming a state in which the force is accumulated. Further, when the wine holder wire 143 is sufficiently rotated, one end of the first locking bar 115 is inserted into the groove 114d, and the gear 114c is fixed in the state of FIG.

A pinion gear 124a is provided on a rotation shaft of the first plate fixing wire 141, and a pinion gear 125a is provided on a rotation shaft of the second dish fixing wire 142. The pinion gear 124a is disposed so that the gears 124b mesh with each other, so that the pinion gear 124a and the gear 124b rotate together. The pinion gear 125a is disposed so that the gears 125b mesh with each other, so that the pinion gear 125a and the gear 125b rotate together.

The dish holder operation part 122 includes a second push bar 123a connected to one end of the contact part pressed by the user, a second locking bar 123b pressed by the second push bar 123a, and the second locking It includes a rack gear (127a) that is limited in movement by the bar (123b) and a second spring (123c) that provides a restoring force to return to the original position when the force is removed from the second locking bar (123b).

The second push bar 123a is pushed rearward based on the drawings of FIGS. 15 and 16 when the dish holder operation part 122 is pressed by the user. In this case, the second push bar 123a may be rotated in a clockwise direction based on a rotation axis disposed in the center. The second push bar 113a has a curved shape rather than a straight line, so that one end is disposed at a position biased toward one side of the rack rather than at the center position of the dish holder operation unit 122. One end of the second locking bar 123b is coupled to the second spring 123c. When the plate holder operation part 122 is pressed, the second push bar 123a is moved backward and the second locking bar 123b rotates clockwise to compress the second spring 123c. At this time, when the pressing force of the plate holder operation unit 122 is removed, the compressed second spring 123c is returned to its original shape, and the plate holder operation unit 122 may return to a non-pressed position.

One end of the second locking bar 123b may have a tapered shape, and a thickness may be relatively thinner toward the end. The second locking bar 123b may form a shape that is bent a plurality of times and may extend in various directions. In particular, the second locking bar 123b may be formed in a shape with one end bent.

A rack gear 127a is provided so as to mesh with the gears 124b and 125b, so that when the rack gear 127a moves left and right, the gears 124b and 125b can be rotated. The pinion gears 124a and 125a coupled to the rotating shaft of the dish fixing wire are rotated by the rotational force transmitted to the gears 124b and 125b, so that the first dish fixing wire 141 and the second dish fixing wire 142 Can be rotated simultaneously. At this time, the pinion gears 124a and 125a are simultaneously rotated in the same direction, so that the first plate fixing wire 141 and the second plate fixing wire 142 are simultaneously rotated from the first position to the second position to be moved. I can.

A third spring 123d is provided on one side of the rack gear 127a, and a damper 129 is provided on the other side of the rack gear 127a. Specifically, a third spring 123d is coupled to the left end of the rack gear 127a, and a damper 129 is coupled to the right end of the rack gear 127a. When the second locking bar 123b is positioned at one end of the rack gear 127a and restricts the movement of the rack gear 127a to the right as shown in FIG. 15, the third spring 123d is compressed. Keep the state. Then, when the user presses the plate holder operation part 122, the second locking bar 123b is rotated clockwise around a rotation center, so that the second locking bar 123b prevents the movement of the rack gear 127a. It can be transformed into a state that cannot be bound At this time, the third spring 123d may move the rack gear 127a to the right by a restoring force. The third spring 123d maintains a compressed state when an external force is applied, and has a restoring force to be tensioned by its original length when the external force is removed. Since the damper 129 disposed at the other end of the rack gear 127a is compressible, it is possible that the speed may be reduced while being compressed. When the rack gear 127a is moved to the right by the restoring force of the third spring 123d, the damper 129 is compressed to the right, and at this time, the speed of the rack gear 127a may be reduced. . That is, the restoring force of the third spring 123d is transmitted to the rack gear 127a as it is, so that when the gears 124a, 124b, 125a, 125b are rotated, the dish fixing wires 141 and 142 may be rotated too quickly. I can. From the user's point of view, when the wire rotates at an appropriate speed and moves from the first position to the second position, the user may receive the impression that it operates stably and prevents damage. In this embodiment to provide such a stable image, the damper 129 is provided on one side of the rack gear 127a, so that the speed of the rack gear 127a is changed.

In a state in which the plate fixing wires 141 and 142 are rotated to the second position, the user may receive the plate between the plate fixing wires 141 and 142. Meanwhile, after the dish washing is completed, the dish fixing wires 141 and 142 may be rotated to the first position using a hand. When the dish fixing wires 141 and 142 are rotated, the gears 124a, 124b, 125a, and 125b are rotated together, and the rack gear 127a may be moved to the left as shown in FIG. 15. When the plate fixing wires 141 and 142 are rotated to the first position, one end of the rack gear 127a is moved to a position capable of being caught by the second locking bar 123b. When the rack gear 127a moves sufficiently to the left, the second locking bar 123b rotates counterclockwise by the restoring force of the second spring 123c, and the left end of the rack gear 127a Even if a user releases his or her hand from the plate fixing wires 141 and 142 by contacting the second locking bar 123b, the rack gear 127a does not move to the left. Accordingly, the plate fixing wires 141 and 142 may overlap with the first wire assembly 130 to achieve a state disposed parallel to the floor.

In a state in which the wine holder wire 143 is rotated to the second position, the user can hang the wine glass on the wine holder wire 143. After washing of the wine glasses is completed, the wine holder wire 143 may be rotated from the second position to the first position using a hand. When the wine holder wire 143 is rotated to the first position, as shown in FIG. 15, the gears 114a, 114b, and 114c are rotated together, and the groove 114d of the gear 114c is caught in the first position. It is inserted into one end of the bar 115 and fixed. Therefore, the wine holder wire 143 may overlap with the first wire assembly 130 to maintain a fixed state.

In addition, among the manipulation units 110, the wine holder manipulation unit 112 and the dish holder manipulation unit 122 are disposed to be spaced apart from each other, and thus operate independently of each other. That is, even if the wine holder operation unit 112 is rotated, the dish holder operation unit 122 is not rotated, and the opposite situation is possible. In a situation where the user does not wash the dishes and only wants to wash the wine glasses, the dish holder operation unit 122 is not operated, and only the wine holder operation unit 112 is operated to store the wine glasses in the rack. On the other hand, in a situation where the user does not wash the wine glasses and only wants to wash the dishes, the wine holder operation unit 112 is not operated, and only the dish holder operation unit 122 is operated to store the plate in the rack.

When the manipulation unit 110 is pressed, the second wire assembly 140 may be rotated. The manipulation unit 110 is pressed downward of the rack, and the second wire assembly 140 is rotated in a clockwise or counterclockwise direction, and thus may be changed from a first position to a second position. In a state in which the wire assembly 140 has moved to the second position, the user may fix some components of the wire assembly 140 by rotating them from the second position to the first position.

17 is a diagram illustrating an operation of a rack according to another embodiment.

The same technology applied to FIGS. 15 and 16 is applied to the rack having the same shape as in FIG. 17, and thus a detailed structure or operation is omitted. In another embodiment, unlike one embodiment, a wall is provided on the rim of the rack. Therefore, it is difficult for the user to manipulate the wire by putting his or her hand inside the rack. In order to improve the user's convenience, the manipulation units 112 and 122 are configured on the front of the rack 100, thereby improving the user's convenience. In the racks 100 and 200, the operation unit 110 is provided on the front of the rack, so that the user can press the operation unit 110 downward to store and wash dishes such as dishes or wine glasses.

The present invention is not limited to the above-described embodiments, and as can be seen from the appended claims, modifications may be made by those of ordinary skill in the field to which the present invention belongs, and such modifications are within the scope of the present invention.
