Description

  The present invention relates to a dishwasher that jets washing water to wash dishes.

  2. Description of the Related Art Conventionally, as a general dishwasher for washing dishes, there is a dishwasher that holds dishes in a dish basket mounted in a washing tank with an upper opening, and that is washed with a washing means that jets washing water (for example, Patent Documents). 1). As shown in FIG. 12, tableware is stored in the lower basket 3 in the lower part of the washing tank 1, in the first upper basket 51 and the second upper basket 52 in the washing tank 1 above the lower basket 3, and downward. A cleaning nozzle that jets cleaning water is used as the cleaning means 7. Hereinafter, the first upper car 51 and the second upper car 52 are collectively referred to as the upper car.

  In such a dishwasher, the dishes are generally stored in order from the lower basket 3. At this time, as shown in FIG. 12, the first upper car 51 is stood up and the tableware is also stored in the lower car 3 below the first upper car 51. When the number of tableware is large, the second upper basket 52 is also stood up and stored in the lower basket 3 below the second upper basket 52. Finally, the upper basket placed upright is returned to its original position, and only cups and hot water are stored on it. Further, by placing the first upper car 51 and the second upper car 52 against each other, a wide open space is formed above the lower car 3 so that large dishes and pots can be stored in the lower car 3. It is. Hereinafter, the open space is also referred to as an open space.

  Moreover, what improves the usability of a standing upper basket like the said patent document 1 WHEREIN: In the tableware dryer and the dishwasher, what can move an upper basket to right and left or back and front is disclosed. Further, Patent Document 2 discloses a tableware dryer in which an upper small basket can be slid or removed in the left-right direction when taking out tableware placed in a lower tray. Furthermore, in Patent Document 3, the upper holding tool (corresponding to the above-described upper basket) can be slid in the front-rear width direction or the horizontal width direction with the object to be cleaned such as a small plate or a cup placed on it. A possible dishwasher is shown. In each of the configurations having the upper and lower tableware baskets so that a larger number of tableware can be accommodated than in the case of only the lower basket, the usability can be improved.

JP 2008-73400 A Japanese Patent Laid-Open No. 5-95885 JP 2005-177255 A

  However, in the case of storing the tableware in the lower basket 3 in the above-mentioned Patent Document 1, in order to store the tableware below the first upper basket 51 and the second upper basket 52, the first upper basket 51, it is necessary to lean the second upper car 52. If there is a tableware previously stored in the first upper basket 51, the tableware is taken out from the first upper basket 51, the first upper basket 51 is leaned and the tableware is stored in the lower basket 3. Thereafter, the first upper basket 51 is returned to the horizontal position, and the tableware is stored thereon, and there is a problem that the convenience of use is not good in that the order of the stored tableware is restricted.

Furthermore, although the tableware stored in the first upper basket 51 is influenced by the shape of the basket and the type of tableware used in each home, it is often only a cup or hot water. Also, only cups and hot water are used frequently, and the number of them may be large. When storing tableware from a table, kitchen, washing tub, etc., into the dishwasher, store tableware in order from the lower basket 3 and finally. In many cases, it is not possible to follow the operation procedure of storing only cups and hot water. That is, dirty dishes may be stored first in the first upper basket 51 and the second upper basket 52, and it is difficult to add the dishes to the lower side. Even if there is a space where dishes can be stored, it is operated as it is, and as a result, the remaining dishes are washed separately, resulting in wasted energy such as using electricity, water and detergent approximately twice. There is a problem of being a thing.

  In particular, when tableware is soaked in a washing bowl or when large stains are washed in advance, the dirty tableware is wet with water. Taking in and out such wet tableware was not easy to use because there was a risk of dropping the tableware and damaging it. Also, because the dishes are dirty and slippery, they are stored in a halfway state (such as when there is contact between the dishes or when the storage angle of the tableware is inappropriate) In some cases, the tableware does not get dirty, the effect of the mechanical cleaning power by the cleaning means 7 is insufficient, and the predetermined cleaning performance may not be obtained.

  Furthermore, in order to take out the tableware stored below the first upper basket 51 and the second upper basket 52 after the operation is finished, at least the tableware stored in the first upper basket 51 and the second upper basket 52 First, the first upper car 51 and the second upper car 52 need to be stood up. The convenience of use is not good also in that the order of the tableware to be taken out is restricted.

  Further, since the first upper basket 51 and the second upper basket 52 need to be stood, the tableware having a relatively flat shape disposed close to the inner surface of the cleaning tank 1 can be stored. Often limited to cups and hot water only. At the same time, in order to obtain washing performance by spraying washing water only on a cup or hot water lying down on the upper basket, the type and size of the tableware stored in the lower basket 3 below the upper basket is limited. It is necessary to increase the spraying speed of the cleaning water by the cleaning means 7, increase the spray flow rate, and increase the mechanical cleaning power. That is, in order to increase the pressurizing capacity of the cleaning water by the cleaning means 7, the pump for pressurizing the cleaning water becomes large, and the entire device becomes larger than the capacity of the dishes to be cleaned. In addition, because the pump can stably pressurize without seeing air, a large amount of cleaning water is used, and a heater is used to heat the cleaning water in order to increase the thermal cleaning power of this large amount of cleaning water. The energy to do also becomes big.

  The thing of patent document 2 is the structure where the accessory basket which slides to a horizontal direction accommodates a cup etc., and its width is also comparatively small. In general, a large-diameter ball or a sieve that is often used has a problem in that it protrudes outside the small basket and cannot be stably stored.

  The device described in Patent Document 3 has a relatively large area of the upper holding tool (corresponding to the upper basket), and is convenient in that a large tableware can be stored in the upper basket. However, when only a small number of cups, hot water, etc. are stored, the upper basket is larger than necessary, so that the open space above the lower holding tool (corresponding to the lower basket) is small. That is, there is a problem in that the size of tableware and pots that can be stored in the lower basket is limited, and the upper basket often becomes an obstacle when storing tableware in the lower basket.

  This invention solves the said conventional subject, and aims at improving the usability regarding storage of the tableware in an upper and lower tableware basket, and improving the washing | cleaning performance.

In order to solve the above-described conventional problems, a dishwasher according to the present invention includes a cleaning tank having an upper opening, a main body for storing the cleaning tank in a horizontal direction, and a tableware provided at a lower portion of the cleaning tank. A cleaning unit for spraying cleaning water onto the tableware in the cleaning tank, and an inner wall of the cleaning tank. A rail that is inclined in the vertical direction to support the upper car, and a tableware guard that indicates an upper limit in the height direction of an object to be cleaned that is placed on the upper car. A stopper for restricting the movement of the upper basket is formed, and the tableware guard is lower than an upper edge portion of the opening of the cleaning tank when the upper basket is at a reference position, and the upper basket slides on the rail and stops the stopper. Higher than the reference position In which substantially formed at the same height as the upper edge of the opening of the cleaning tank is time.

  As a result, when the object to be cleaned is stored in the upper basket in the range of the upper limit indicated by the tableware guard, the upper basket is placed at the reference position of the cleaning tank (the lower position of the inclined rail, and the upper basket is stabilized. When the upper car is moved horizontally from the position where it also stands still, the upper car slides on the inclined rail, the height rises, and the stopper comes into contact with the stopper, thereby restricting the movement of the upper car. At this time, since the tableware guard of the upper basket is substantially the same height as the upper edge of the cleaning tank, the cleaning tank is housed in the main body in this state, and the object to be cleaned comes into contact with the main body, or the object to be cleaned is in the cleaning tank It can be prevented from being damaged by being pinched by the body. In addition, the table can be horizontally moved while the tableware is stored in the upper basket, and the tableware in the lower basket can be easily stored and taken out. In addition, by moving the position of the upper basket so as not to overlap with the tableware of the lower basket, the cleaning water jet by the cleaning means is surely given to the tableware of the upper basket, and the cleaning performance is improved. Furthermore, since the sliding portion of the upper cage and the rail is inclined in the vertical direction, the cleaning water quickly flows in the inclined direction at the sliding portion, and there is no accumulation of contaminants cleaned from the object to be cleaned. The amount of water droplets attached is small and the cleaning performance is improved.

  The dishwasher of the present invention can easily set dishes, is easy to use, has little waste of energy, and can improve cleaning performance.

1st invention is the upper part of the said washing tank, the main body which accommodates the washing tank which opened upwards, the main body which accommodates the said washing tank so that pull-out is possible in the horizontal direction, the bottom provided in the lower part of the said washing tank, and holding tableware The upper basket that holds the tableware and moves in the horizontal direction, injects cleaning water into the tableware in the cleaning tank, and is inclined on the inner wall of the cleaning tank in the vertical direction. And a tableware guard indicating the upper limit in the height direction of the object to be cleaned placed on the upper basket, and a stopper for restricting the movement of the upper basket is formed on the side wall of the cleaning tank, The tableware guard is lower than the upper edge of the opening of the washing tub when the upper basket is in the reference position, and the upper basket slides on the rail and abuts against the stopper and is higher than the reference position. Same as the upper edge of the opening of the cleaning tank When the object to be cleaned is stored in the upper range of the upper limit indicated by the tableware guard, the upper basket is moved horizontally from the reference position of the cleaning tank. Then, the upper car slides on the inclined rail, and the height rises and comes into contact with the stopper, thereby restricting the movement of the upper car. At this time, since the tableware guard of the upper basket is substantially the same height as the upper edge of the cleaning tank, the cleaning tank is housed in the main body in this state, and the object to be cleaned comes into contact with the main body, or the object to be cleaned is in the cleaning tank It can be prevented from being damaged by being pinched by the body. In addition, the table can be horizontally moved with the tableware stored in the upper basket, and the tableware in the lower basket can be easily stored and taken out. In addition, by moving the position of the upper basket so as not to overlap with the tableware of the lower basket, the cleaning water jet by the cleaning means is surely given to the tableware of the upper basket, and the cleaning performance is improved. Furthermore, since the sliding portion of the upper cage and the rail is inclined in the vertical direction, the cleaning water quickly flows in the inclined direction at the sliding portion, and there is no accumulation of contaminants cleaned from the object to be cleaned. The amount of water droplets attached is small and the cleaning performance is improved.

  In the second invention, in particular, the rail of the first invention is formed in two vertical stages in the vertical direction, and when the upper car is installed on the lower rail, it does not contact the stopper, so that the movement of the upper car is restricted by the stopper. It will not be done. With a large number of items to be cleaned in both the upper and lower baskets, the upper basket can be moved horizontally until it comes into contact with the front and rear inner surfaces of the cleaning tank. Therefore, it is possible to secure a large open space for the front and rear of the washing tank, so that the usability is improved. In addition, various shapes of objects to be cleaned can be stored in the lower basket in a direction that is easy to handle using a large open space, so that the objects are securely held so as not to wobble, and the cleaning performance is stabilized.

  In the third invention, in particular, the tableware guard according to any one of the first to second inventions is formed on the back of the upper basket so as to be rotatable in the moving direction of the upper basket, and the tableware guard in the vertical state serves as a stopper. When the object to be cleaned is stored in the upper basket by abutting, the tableware guard is in a vertical state and indicates the upper limit in the height direction of the object to be cleaned, and at the same time the tableware guard abuts against the stopper. The movement is restricted, the front position of the upper car sliding relative to the inclined rail is restricted, and at the same time the height position of the upper car is restricted. That is, the position control of the upper basket is performed in conjunction with the tableware guard in a vertical state for storing the objects to be cleaned.

  In the fourth invention, in particular, when the tableware guard of any one of the first to third inventions does not come into contact with the stopper when rotating forward, when the object to be cleaned is not stored in the upper basket, Alternatively, when the tableware guard is rotated forward so as to cover the short, light object to be cleaned stored in the upper basket, the movement of the upper basket is not restricted because the tableware guard does not contact the stopper. In addition, by forming a tableware storage unit that holds tableware on both the upper and lower sides in this way, tableware storage units such as tableware that is light enough to be blown away by the jet of washing water, resin containers and lids, etc. It can be stored and washed. In addition, items that can only be stored in an unstable manner due to their long and irregular shape, such as ladle and chopsticks, are held in the tableware storage unit on both the top and bottom sides, making them easy to use. In particular, as with light tableware, washing water is sprayed onto the object to be washed that is stationary in the tableware storage, so that the mechanical washing power obtained by multiplying the washing water speed and flow rate by the washing means is maximized. The cleaning performance is stabilized by the chemical cleaning power of the detergent and the thermal cleaning power of the cleaning water heated by the heater.

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

(Embodiment 1)
1 to 6 show drawings of this embodiment.

As shown in FIG. 1, the washing tank 1 is accommodated in the main body 2 of the dishwasher. The main body 2 is incorporated in the kitchen, has an opening on the front surface, and a cleaning tank 1 with an upper opening.
Is stored in such a manner that it can be pulled out horizontally. As shown in FIG. 2, a lower basket 3 that holds tableware in the lower part of the washing tank 1, a first upper basket 4a that holds tableware in the upper part of the washing tank 1 and moves in the horizontal direction as indicated by an arrow S1, A second upper basket 4b detachably connected to the first upper basket 4a and a cleaning means (cleaning nozzle) 7 for injecting cleaning water onto the tableware are provided.

  Also, as shown in FIG. 3, there is a tableware guard 6 indicating the upper limit in the height direction of the tableware placed on the first upper basket 4a, for example, a cup 34, on the back surface of the first upper basket 4a. The height of the tableware guard 6 is lower than the upper edge of the washing tank 1 by H0. When the tableware lower than the tableware guard 6 is placed, the tableware and the washing tub 1 can be stored in the main body 2 without the tableware coming into contact with the main body 2.

  In addition, since the first upper basket 4a and the second upper basket 4b are connected and move horizontally as a whole, they are collectively referred to as an upper basket for holding tableware. In addition, the lower basket 3 has an accessory case 3a for storing a fork, a spoon and the like in a detachable manner. Furthermore, a water supply means for supplying cleaning water to the cleaning tank 1, a pump for pressurizing the cleaning water and supplying it to the cleaning means 7, a heater for heating the cleaning water to a required cleaning temperature, and a control for controlling the operation of these components Means and element members necessary for a general dishwasher, such as an operation panel operated by a user, are included, but they are not essential for explaining the effects peculiar to the present invention.

  First, the usage as a dishwasher and the operation of the device are the same as those of a general household dishwasher, but will be described with reference to the drawings.

  In the state shown in FIG. 1, the user pulls the cleaning tank 2 forward from the main body 2, and in the state shown in FIGS. 2 and 3, objects to be cleaned such as dishes and pots are placed in the lower basket 3 of the cleaning tank 1, the first Set in the upper basket 4a. The lower basket 3 is attached to the lower part of the washing tank 1 and has a pin shape for holding the tableware in a direction suitable for washing. Further, the first upper car 4a is provided with sliders 10a and 10b as shown in FIG. 4 on both sides, and these are mounted on a rail 11 provided in the front-rear direction on the inner surface of the cleaning tank 1 and slide on the rail 11. It can move in the horizontal direction in the front-rear direction in the cleaning tank 1. When the object to be cleaned is stored, the detergent is put in, the cleaning tank 1 is stored in the main body 2, and the start of operation is operated on the operation panel.

  Subsequently, the control means controls the operation of the water supply means, the pump, the heater, etc., so that the washing process is performed by spraying the pressurized and heated washing water from the washing means 7 and washing the dishes. The step of washing with washing water containing a detergent is called a main washing step, and the step of washing after replacing the washing water is also called a rinsing step. The cleaning means 7 is composed of an arm-shaped cleaning means for spraying cleaning water pressurized by a pump while rotating horizontally, and a tower-shaped cleaning means at the center of rotation, and is also called a cleaning nozzle. Furthermore, following the cleaning process, a drying process is performed in which the object to be cleaned is dried by operating a heater, a blower, or the like, but the description thereof is omitted here.

  Next, a description will be given focusing on the unique configuration and operation in the first embodiment.

  First, as shown in FIG. 2 and FIG. 3, the open space 8 indicated by a dotted line in FIG. 2 in a state where the tableware is stored in the lower basket 3, the first upper basket 4 a and the second upper basket 4 b. That is, the tableware of the lower basket 3 is confirmed from the upper part of the washing tank 1 through the space not occupied by the first and second upper baskets 4a and 4b in the upper space of the lower basket 3, and the tableware can be added or removed. Yes. In particular, since the first upper basket 4a is configured to move horizontally in the washing tank 1 as indicated by the arrow S1 via the rail 11, an open space 8 through which the lower basket 3 can be seen can be formed before and after the washing tank 1. The tableware stored before and after the lower basket 3 can be confirmed, and the tableware can be added or removed.

When the connected upper basket moves to the rear part of the cleaning tank 1, the open space 8 is at the front part of the cleaning tank 1. When the connected upper basket moves to the front of the washing tank 1 as indicated by the arrow S1, the open space 8 is located at the rear of the washing tank 1 and the upper basket is placed with only the cup 34 and hot water 35 stored therein. Can move. Of course, since the connecting portion 9 between the first upper car 4a and the second upper car 4b is detachable, the table is stored only in the first upper car 4a and the second upper car 4b is removed. When the first upper car 4a is moved horizontally, the open space 8 through which the lower car 3 can be seen is further enlarged by the size of the second upper car 4b, and the lower car 3 can be easily stored. Can store large dishes and pots. Furthermore, by moving the position of the upper basket so as not to overlap with the tableware of the lower basket 3, the washing water jetting by the cleaning means is surely given to the tableware of the upper basket, and the cleaning performance is improved.

  If it is such a structure, since the order of the tableware stored is not restrict | limited by the upper cage | basket | car and the lower cage | basket | car 3, it is convenient. In addition, the open space 8 through which the lower basket 3 can be seen allows a large number of dishes to be stored without any gaps while confirming whether or not the set state is appropriate for the direction that can be cleaned. As a result, the number of operations is small, so there is no waste in electricity, water and detergent. Furthermore, the upper basket can be moved at any time, and the storage state of the tableware can be confirmed by the open space 8, and a predetermined cleaning performance can be obtained.

  Secondly, a rail 11 that is formed on the inner wall of the cleaning tank 1 so as to be inclined in the vertical direction and supports the upper car, and a tableware guard 6 that indicates an upper limit in the height direction of an object to be cleaned placed on the upper car; , And a stopper 15 is formed on the side wall of the cleaning tank 1 to regulate the range in which the upper basket moves on the rail 11. As shown in FIG. 3, the rail 11 is inclined so that its position is lowered from the front part to the rear part of the cleaning tank 1. Therefore, when the upper car is at the lower position of the rail 11, even if the washing tank 1 is moved back and forth, the upper car is stabilized at the lower position, so this position is determined as the reference position. The tableware guard 6 is lower by H0 than the upper edge of the opening of the cleaning tank 1 when the upper basket is at the reference position of the cleaning tank 1, and when the upper basket slides and rises on the rail 11, Abut. That is, it is configured to be substantially the same height as the upper edge of the opening of the cleaning tank 1 when it is at a position higher than the reference position.

  With this configuration, when an object to be cleaned such as a cup 34 is stored in the upper basket in the range of the upper limit indicated by the tableware guard 6, if the upper basket is moved horizontally from the reference position of the cleaning tank 1, The car slides on the inclined rail 11 and comes into contact with the stopper 15 by raising the height position, and the movement of the upper car is restricted in the state shown in FIG. Thus, when the tableware guard 6 contacts the stopper 15, the upper end of the tableware guard 6 of the upper basket is substantially the same height as the upper edge of the cleaning tank 1, so that the cleaning tank 1 is stored in the main body 2 in this state. Then, it is possible to prevent the object to be cleaned such as the cup 34 from coming into contact with the main body 2 or being damaged by being sandwiched between the cleaning tank 1 and the main body 2. Further, since the sliding portion of the upper cage and the rail 11 is inclined in the vertical direction, the cleaning water quickly flows in the inclined direction at the sliding portion in the cleaning process, and the contaminants cleaned from the object to be cleaned are accumulated. Nor. Furthermore, the amount of dirty water droplets attached is small, and an efficient rinsing performance in the cleaning process can be obtained, thereby increasing the cleaning performance.

  Third, as shown by the arrow T, the tableware guard 6 rotates in the direction of movement of the upper car on the back of the first upper car 4a, with the vicinity of the upper end of the back of the first upper car 4a as the rotation axis. When the table upper guard 4a is moved forward when the tableware guard 6 is in a vertical state, the tableware guard 6 and the stopper 15 are in contact with each other.

  In this configuration, in order to store an object to be cleaned such as a cup or hot water in the first upper basket 4a, the tableware guard 6 is in a vertical state and indicates the upper limit in the height direction of the object to be cleaned. Further, the tableware guard 6 provided on the first upper car 4a abuts against the stopper and the movement of the first upper car 4a is restricted, so that it slides on the inclined rail 11 and moves forward from the reference position. The foremost position of the first upper car 4a to be moved is determined. That is, the uppermost position of the height position of the upper car is determined.

  Fourth, as shown by the arrow T, the tableware guard 6 is formed on the back surface of the first upper basket 4a so as to be rotatable in the moving direction of the upper basket, and when the tableware guard 6 rotates forward, the tableware guard 6 6 and the stopper 15 are not in contact with each other.

  In this configuration, as shown in FIG. 6, when the tableware guard 6 is rotating forward, the first upper basket 4 a slides on the rail 11, and the tableware guard 6 passes under the stopper 15. The upper basket can be moved to the front surface of the washing tank 1. That is, the tableware guard 6 is rotated forward so that the object to be cleaned is not stored in the first upper basket 4a, or so as to cover the light object to be cleaned, which is stored in the first upper basket 4a, from above. When moved, the tableware guard 6 does not come into contact with the stopper 15, so that the movement of the first upper car 4a is not restricted. In this way, by moving the first upper basket 4a and the second upper basket 4b forward, the tableware guard 6 uses the open space 8 without being obstructed, and stores the tableware in the rear part of the lower basket 3. Cheap. Moreover, it is easy to take out.

  The first upper basket 4a and the tableware guard 6 form a tableware storage section that covers the tableware from the upper and lower sides, so that the tableware is light enough to be blown away by the spray of washing water, a resin container, a lid, etc. Can be stored and washed. In addition, items such as ladle and chopsticks that were long and deformed and could only be stored in an unstable manner are held in the tableware storage unit on both the top and bottom, making it easy to use. In particular, as with light tableware, washing water is sprayed onto the object to be washed that is stationary in the tableware storage, so that the mechanical washing power obtained by multiplying the washing water speed and flow rate by the washing means is maximized. The cleaning performance is stabilized by the chemical cleaning power of the detergent and the thermal cleaning power of the cleaning water heated by the heater.

  Further, since the first upper car 4a and the second upper car 4b are folded with each other around the connecting portion 9, a light object to be cleaned can be accommodated between them. In this case, at the same time, the projected area of the upper car is halved, and when the tableware is stored in the lower car 3, the upper car does not get in the way and the open space 8 becomes vast. In addition, by moving the upper basket, such a large open space 8 can be configured either before or after the cleaning tank 1, which is convenient.

  The connecting portion 9 is composed of a bearing portion (hole) provided in the first upper car 4a and a shaft provided in the second upper car 4b, and the second upper car 4b is connected to the first upper car 4a. On the other hand, it is rotatable around the connecting portion 9. It is also possible to form a shaft on the first upper car 4a and a bearing portion on the second upper car 4b.

  Note that the second upper car 4b protrudes between the first upper car 4a so that the rotation in the direction opposite to the above is limited to a predetermined range, that is, the second upper car 4b does not turn beyond the horizontal state. The contact part is provided in several places. Further, as a configuration in which the second upper car 4b is detachably connected to the first upper car 4a, in the embodiment, the second upper car 4b is rotated at a predetermined angle from the vertical direction. The second upper car 4b is slid leftward and separated so as to extract the shaft from the bearing part (hole) of the connecting part 8.

  As shown in FIG. 3, the first upper car 4a and the second upper car 4b are connected to move in the horizontal direction as a unit. A large-diameter pan that spans both the basket 4 b can be stored, and the pan can be moved to store tableware in the lower basket 3.

  Fifthly, as shown in FIGS. 3 and 4, the first upper car 4a has convex sliders 10a and 10b, and the rail 11 supports the first upper car 4a via the sliders 10a and 10b. Since the contact area between the slider 10 and the rail 11 is small, the frictional resistance is small, the first upper cage containing a large number of dishes and the second upper cage connected thereto move horizontally with a small force. .

  Further, by providing a gap through which the cleaning water passes between the rail 11 and the cleaning tank 1 as the cleaning water guide portion 12 (see FIG. 3), the cleaning water guide portion 12 of the cleaning tank 1 and the rail 11 in the cleaning process. Wash water passes through the rail 11, and the contaminants of the tableware do not accumulate on the rail 11, the side surfaces of the upper basket, the sliders 10a and 10b, and the wall surface of the cleaning tank 1. Tableware contaminants include large stains such as rice grains and leftovers, fine stains from which they are crushed, and many other fine stains. Rise. And the washing | cleaning performance of tableware is ensured because the contaminant wash | cleaned from the tableware does not adhere to tableware again.

  In addition, the rail 11 has the slider holding portion 13 that restricts the vertical movement of the slider 10, so that the first upper basket 4 a is horizontal regardless of the movement of the center of gravity due to the way the tableware is placed on the first upper basket 4 a. The state is stable, the positional relationship between the cleaning means 7 and the tableware is constant, and a predetermined cleaning performance is obtained. In addition to the weight of the tableware itself, when the tableware is placed, the user's operation force is applied, but the upper basket is stable in a horizontal state, and there is no fall damage of the tableware.

  Further, two sliders 10a and 10b are provided for the rail 11 on one side. The distance between the two sliders 10a and 10b in the horizontal direction (also referred to as the convex pitch of the slider 10) and the vertical gap between the sliders 10a and 10b and the slider holding portion 13 of the rail 11 (upper and lower margins). It can be said that the rattling of the first upper car 4a is determined, and this rattling can be reduced. That is, the first upper basket 4a is held almost horizontally, and the tableware is stable when the first upper basket 4a is slid. Moreover, since the cross section of the convex sliding part of slider 10a, 10b is circular and the sliding surface of the rail 11 is a straight line, these are point contacts. The slidability between the sliders 10a and 10b and the rail 11 is ensured, and the operating force to slide the first upper car 4a, that is, the entire upper car is small and convenient. Furthermore, since the contact portion between the slider 10 and the rail 11 is small, there is little accumulation of dirt during the cleaning operation, and the cleaning performance is maintained.

  Further, at least the rail 11 and the sliders 10a and 10b are arranged on the left and right in the horizontal movement direction, and the sliders 10a and 10b have two convex shapes on the front and rear and four convex shapes on the left and right. With this configuration, regardless of the change in the position of the center of gravity of the entire upper basket due to the order of storage of the dishes in the upper basket, the place of placement, etc., the upper basket does not tilt greatly back and forth, or tilts left and right. The upper car 4a and the second upper car 4b are stationary in a horizontal state. That is, when loads in various directions are generated in the upper car, there is no fear that the first upper car 4a is greatly tilted up and down and floats and the tableware falls.

  Of course, the plane part in which the first upper basket 4a and the second upper basket 4b store the tableware is predetermined with respect to the horizontal plane in order to ensure the cleaning performance of the object to be cleaned and improve the drainage of the object to be cleaned. Needless to say, the angle may be as follows.

  The entire shape of the sliders 10a and 10b may be long in the moving direction of the upper car. In this case, in order to reduce the resistance of the sliding portions between the sliders 10a and 10b and the rail 11, a material having a good slidability and a combination thereof may be considered, and the slider may be configured as a single slider. That is, the specific shape is not limited to the embodiment.

  In the embodiment, the rail 11 has a concave portion and the sliders 10a and 10b have convex portions. However, the relationship between the concave and convex portions is reversed, the rail 11 has a convex shape, and the sliders 10a and 10b have a concave shape. But that's fine.

Moreover, when the upper basket is moved variously back and forth by storing the tableware by arranging the predetermined position of the cleaning tank 1, that is, the reference position, on the low position side of the rail 11, The user can move the upper car to the reference position with a small force in the inclined direction of the rail 11. Further, when the upper car is moved in a state where the tableware is stored in the lower car 3 in advance, the upper car moves horizontally while rising from the reference position. Since the distance between the tableware stored in the lower basket 3 and the moving upper basket is the direction in which the distance is increased and separated, it is difficult for these to collide and the tableware to be damaged. For example, since the distance from the elongated small items such as chopsticks stored in the small item case 3a is increased, the small items are hardly caught and damaged.

(Embodiment 2)
7 to 11 show drawings of the second embodiment.

  The basic configuration and operation are the same as in the first embodiment, and the description of common parts is omitted. The rails 11 are arranged in two vertical stages in the vertical direction, and are different from the first embodiment in that the upper car is placed and moved on either the upper rail 11a or the lower rail 11b. In the following, a description will be given focusing on the specific action in the second embodiment. Further, the upper car is the same as in the first embodiment, and as shown in FIG. 4, the first upper car 4a has sliders 10a and 10b.

  As shown in FIG. 8, the rail 11 includes two upper and lower upper rails 11 a and 11 b in the vertical direction, and the upper car is placed on one of the rails 11 and slides on the selected rail 11. is there. For this purpose, as shown in FIG. 7, the rails 11 are respectively located at positions closer to the front of the cleaning tank 1, and the slider guides opened upward to which the sliders 10a and 10b of the first upper car 4a shown in FIG. The upper cage can be attached to the upper rail 11a or the lower rail 11b by attaching the sliders 10b and 10a to the slider guide portion 16 of the upper rail 11a or the lower rail 11b in this order.

  First, when the upper basket is installed on the upper rail 11a, the tableware guard 6 comes into contact with the stopper 15 as shown in FIG. 9, and the movement of the upper basket is restricted by the stopper. That is, when the upper rail 11a is inclined in the up-down direction as in the first mode, the further raising of the upper car is restricted by restricting the movement of the upper car. Therefore, in this state, when the cleaning tank 1 is stored in the main body 2, the upper basket or the object to be cleaned does not come into contact with the main body 2.

  Next, as shown in FIG. 10, when the upper basket is installed on the lower rail 11b, the position of the tableware guard 6 is lower than the distance H0 from the upper edge of the cleaning tank 1 shown in the first embodiment. . For this reason, when the upper basket is slid, the tableware guard 6 passes below the stopper 15, and the tableware guard 6 does not contact the stopper 15, and the movement of the upper basket is not restricted by the stopper 15 (FIG. 11). That is, in a state where a large number of objects to be cleaned are stored in both the upper car and the lower car 3, the upper car can be moved horizontally until it contacts the front and rear inner surfaces of the cleaning tank 1. Since a large open space for storing and taking out can be secured before and after the washing tank, usability is improved. In addition, using a large open space with the upper basket and the washing tub 1, objects to be cleaned of various shapes can be stored in the lower basket in a direction that is easy to handle. The cleaning performance is stabilized.

  In the first and second embodiments, the horizontal movement direction of the upper basket coincides with the drawing direction of the cleaning tank 1, but the present invention is not limited to this. For example, the horizontal movement of the upper basket may be perpendicular to the direction in which the cleaning tank 1 is drawn. Furthermore, if the washing tank 1 has a shape that is long in the pull-out direction, the first upper basket 4a can store a cutting board or the like without providing the long and large escape portion 4c (see FIG. 7) provided in the above embodiment. The area where tableware can be stored in the first upper basket 4a is increased. Further, when the horizontal width of the cleaning tank 1 is long, even if the horizontal movement direction of the upper basket coincides with the drawing direction of the cleaning tank 1, a cutting board or the like is provided in the horizontal width direction without providing the long-sized escape portion 4b. Needless to say, it can be stored.

  In the first and second embodiments, the main body 2 is incorporated in the kitchen, but the present invention is not limited to this. For example, even if the washing tank 1 is pulled out, it may not be incorporated in the kitchen if there is a fall prevention means such as a means for fixing the main body 2 to the floor so as not to fall.

  In Embodiments 1 and 2, the shape of the upper basket is such that only the cup 34 or hot water 35 is stored in an inclined state so as to obtain cleaning performance and drying performance. For this reason, the rail 11 and the sliders 10a and 10b have different shapes on the left and right so that they cannot be mounted if the upper car is mounted in the wrong direction, but this is a general structural device. Detailed illustration is omitted. It goes without saying that depending on the configuration of the cleaning means 7 and the jetting ability, the cleaning performance can be exhibited regardless of whether the upper car is mounted in the front-rear direction. In this case, even if the first upper basket 4a and the second upper basket 4b are each limited in the type of tableware, the one that is used more frequently is mounted on the back side of the washing tub 1, etc. Appropriate usage is possible.

  In Embodiments 1 and 2, a single upper basket or two connected upper baskets can be removed at the same time, so that larger objects to be cleaned such as larger dishes, pans, trays and cutting boards can be placed in the lower basket 3. Easy to store and clean. In addition, since only one of the upper cars (the first upper car 4a in the embodiment) is placed on the rail 11, two upper cars can be mounted at the same time, so there is no possibility of forgetting to attach or losing them.

  In the first and second embodiments, as a means for adjusting the height positions of the first upper car 4a and the second upper car 4b, the height position in the cleaning tank 1 is adjusted in a single rail 11. Means to do this may be configured. Further, the rail 11 may be arranged at a fixed position and the upper car itself may be provided with a height adjusting function. For example, a means for adjusting the height positions of the sliders 10a and 10b of the first upper car 4a may be configured. As a result, a larger object to be cleaned can be stored in the upper basket, but adjusting the height of the upper basket in the vertical direction in this way is also a general configuration in a dishwasher, and will be described in detail. Is omitted.

  The stopper 15 may be in contact with the outer shape other than the upper basket 4 and the tableware guard 6 to restrict the movement of the upper basket 4 in the front-rear direction. For example, the rail 11 has two upper and lower stages, and the user can select the rail 11 so that the upper car does not contact the rail at the same time. In this case, the trouble of rotating the tableware guard 6 as in the first and second embodiments is unnecessary.

  In the first and second embodiments, the stopper 15 is provided on the inner wall of the cleaning tank 1, but the movement may be restricted by contacting a part of the rail 11 or the lower basket 3.

  In the first and second embodiments, the rail 11 is in close contact with the inner wall of the cleaning tank 1 and is fixed, but a certain distance may be provided. Further, it may be configured to slide back and forth in accordance with the movement of the upper car 4.

  In Embodiments 1 and 2, it is assumed that the washing tank 1 is pulled out from the main body 2. However, even in a dishwasher having a lid structure for opening and closing the upper open space of the washing tank 1, the upper basket and stopper It goes without saying that the same effect can be obtained by the configuration.

In the first and second embodiments, the cleaning means 7 is composed of a horizontally rotating arm-shaped cleaning means and a tower-shaped cleaning means. However, an arm-shaped cleaning nozzle is provided below the lower basket 3 and the upper basket. Or a cleaning nozzle may be provided on the wall surface of the cleaning tank 1 or above the upper basket.

  The dishwasher of the present invention is useful in that it further improves the storage capacity and usability of tableware and improves the cleaning performance.
