Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a dishwasher.

[Prior Art] There is known a dishwasher installed in a kitchen or the like and used for washing dishes. In this dishwasher, there are known a dishwasher in which the dish is put in and taken out from the front and a dish which is carried out from the top.

Among them, the one in which tableware is taken in and out from the top side does not require a space for the tableware to be put in and taken out on the front side, and therefore has an advantage that the floor area occupied for installation and work is small. There is.

However, since most of the dishes washed in the dishwasher are made of pottery or glass, the total weight of the dishes in the dish rack increases when they are stored together, and the dish rack in this state is stored in the washing room from the top of the dishwasher. However, taking it out was a difficult task. For this reason, for example, tableware is manually put in and taken out from a tableware rack that has been inserted into the washing room in advance, which is inferior in work efficiency.

As one for efficiently performing such tableware storing work, a dishwasher has been proposed in which a dish rack can be retracted from an opening on the upper surface of the dishwasher, and for example, dishware disclosed in Japanese Utility Model Publication No. 59-37062. There is a washing machine.

[Problems to be Solved by the Invention] However, in the dishwasher disclosed in Japanese Utility Model Laid-Open No. 59-37062, since the lid of the upper opening moves up and down together with the dish rack, the lid is placed above the dishwasher. It is necessary to secure a moving space, and if there is a shelf or the like at the position where the lid should move, a dishwasher cannot be installed, which has been a problem.

Further, since the lid is fixedly arranged on the tableware rack above the tableware rack, the work of putting in and taking out the tableware to and from the tableware rack has to be performed while avoiding the lid, which places a heavy burden on the operator.

[Means for Solving the Problem] In order to solve this problem, a dishwasher of the present invention has a cylindrical main body having a washing chamber which is opened at an upper end and can store a dish rack therein, and the washing chamber. A washing nozzle installed in the upper and lower positions of the washing nozzle for injecting washing water into the inside of the washing chamber, and an elevating mechanism for elevating and lowering the dish rack so that the dish rack is retracted from the opening. A pantograph-type lifting device, which is held at one end on the bottom surface of the chamber and is capable of expanding and contracting in the vertical direction, and a drive means for driving the pantograph-type lifting device to expand and contract, and a horizontal movement range along the opening are provided. A slide shutter that can be fully opened and fully closed by moving horizontally and vertically along a vertical movement area along the side wall of the main body, and when the opening is fully opened, almost all the shutter is accommodated in the vertical movement area. By providing a receiving frame which is mounted on the upper end of the pantograph type lifting device and on which the tableware rack can be placed, the tableware placed on the receiving frame according to expansion and contraction of the pantograph type lifting device. It is characterized in that the rack can be moved up and down within a range between the position where the rack is completely exposed above the opening and the cleaning chamber.

[Operation] In the dishwasher having the above configuration, the slide shutter moves horizontally to fully open and close the opening, and when the slide shutter is fully opened, almost the entire slide shutter is housed in the vertical movement area along the side wall, so the lid is opened and closed. It is not necessary to secure a space for the above or above the opening. Therefore, the space required for installing the dishwasher is small, and the space utilization efficiency is improved.

Also, for example, even if there is a shelf or the like above, the dishwasher can be installed. Therefore, the dishwasher can be installed in various places, and the degree of freedom in selecting the installation place is increased.

In addition, it is not necessary to avoid the lid to perform the work of loading and unloading the dishes to and from the dishwasher, and the burden on the worker is reduced.

Further, a receiving frame is attached to the upper end of the pantograph type lifting device, and a tableware rack can be placed on the receiving frame. The tableware rack placed on this receiving frame is
It can be raised and lowered within the range exposed from the opening. Therefore,
For example, place a dish rack on the workbench adjacent to the dishwasher, fill it with the dishes to be washed, and then move the dish rack along the horizontal direction so that the dish rack rises to the opening. Can be placed. For this reason, since the movement of the table rack that stores the tableware and is heavy only needs to be performed in the horizontal direction, the burden on the operator in the movement of the table rack is reduced.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the main body 1 has a rectangular tubular shape with a substantially square cross section, is installed along the axis in a substantially vertical direction, and has an opening 2 at the upper end. Along the opening 2, a horizontal movement area of a sliding shutter 3 of a shutter type is provided.

The slide shutter 3 can be moved in this horizontal movement area and a vertical movement area along the side surface of the main body 1, and the opening 2 can be fully opened and fully closed according to the movement in the horizontal movement area. Almost the whole is stored in the vertical movement area. Therefore, above the opening 2 or on the side of the main body 1,
When opening and closing the opening 2, no special space is required for moving the door, for example.

A pair of upper jet nozzles 4 and 4 are arranged substantially horizontally below the horizontal movement region of the slide shutter 3, and the cleaning liquid can be jetted obliquely downward from the upper jet nozzles 4 and 4. To the upper injection nozzles 4 and 4, pipes that descend along the side wall of the main body 1 and penetrate the bottom surface 7 are connected,
This pipe is connected to a water pump 11 installed in the space below the bottom surface 7. Further, the water jet pump 11 is connected to a rotary injection nozzle 5 attached to the tip of the vertical pipe via a vertical pipe standing upright at approximately the center of the bottom surface 7. As a result, from the water pump 11 to the upper injection nozzles 4, 4,
Also, cleaning water can be supplied to the rotary jet nozzle 5. The upper jet nozzles 4 and 4 and the rotary jet nozzle 5 are
It is housed in a cleaning chamber 6 defined by a bottom surface 7 and a side wall.

As shown in FIG. 1, FIG. 2, and FIG. 3, a pantograph type lifting device 8 having one end held on a bottom surface 7 is installed in the cleaning chamber 6. This pantograph type lifting device 8
The end portion of the bottom surface 7 side is connected to the hydraulic cylinder 10. The hydraulic cylinder 10 is connected to a water supply or a water pump via a controller (not shown), and can extend and retract the pantograph-type lifting device 8 according to the supply and discharge of water via the controller.

On the other hand, a receiving frame 9 is attached to the other end of the pantograph type lifting device 8, and the tableware rack A can be placed on the receiving frame 9. The receiving frame 9 is in a state in which the placed tableware rack A is positioned in the middle of the upper injection nozzles 4 and 4 and the rotary nozzle 5 in the washing chamber according to the expansion and contraction of the pantograph type lifting device 8 (FIGS. 1 and 2). (See the figure) From tableware rack A, the bottom of tableware rack A is almost at the same level as opening 2, and tableware rack A
Can be moved up and down to a position where it is almost completely exposed from the dishwasher (see FIG. 3). In addition, during this lifting, due to the well-known characteristics of the pantograph lifting device 8, the receiving frame 9
The tableware rack A placed on the receiving frame 9 remains horizontal.

When storing tableware in this dishwasher, first, the slide shutter 3 is fully opened. Next, the hydraulic cylinder 10 is operated to drive the pantograph-type lifting device 8 to move the receiving frame 9 to the third position.
Position as shown.

In this state, the tableware rack A in which the tableware is stored and placed on another cooking table B in advance is placed on the receiving frame 9. Since it is only necessary to horizontally move the tableware rack A that stores tableware and is increasing in weight, the burden of moving the tableware rack A is reduced.

Alternatively, at this time, after the tableware rack A is placed on the receiving frame 9, tableware may be placed on the tableware rack A.

Since there is no member such as a door that interferes with the storage work above the receiving frame 9 or above the tableware rack A placed on it, the work of storing the tableware is easy and the burden on the operator is reduced.

Then, the pantograph type lifting device 8 is lowered to close the slide shutter 3 (see FIGS. 1 and 2), and a cleaning operation is performed.

In order to take out the washed tableware, first, the slide shutter 3 is fully opened, and then the tableware rack A is raised together with the receiving frame 9 to the state shown in FIG. Here, if the tableware rack A is removed from the receiving frame 9, the washed tableware can be collectively taken out. As with the tableware storing work, the tableware taking-out work is easy.

Further, if the tableware to be washed is stored in the tableware rack A ′ in advance, and after the tableware rack A is removed and the tableware rack A ′ is placed on the receiving frame 9, the washed tableware can be obtained. Since the taking out and the tableware to be washed next can be continuously stored in the washing chamber 6, the working efficiency is improved.

In addition to the hydraulic cylinder, a known mechanism using, for example, a rack-pinion or a crank having a motor as a drive source can be used as the drive means.

[Effects of the Invention] As described above, the dishwasher of the present invention employs the slide shutter that is housed in the vertical movement area along the side wall of the main body when fully opened, so that the dishwasher can be installed above or to the side of the dishwasher. , It is not necessary to secure a space for opening and closing the opening, the space utilization efficiency is improved, and the degree of freedom of the installation place is excellent.

Further, when the opening is opened, there is no member such as a door above or around the opening that obstructs the tableware loading / unloading work, so that the tableware loading / unloading work is easy and the burden on the operator is reduced.

Moreover, since the tableware rack can be moved only horizontally when the tableware is taken in and out, the burden on the operator associated with this work is reduced. In addition, the tableware to be washed is stored in another tableware rack in advance, and following removal of the washed tableware rack from the receiving frame, the tableware rack containing the tableware to be washed is received in the frame. If it is placed on the table, it is possible to take out the washed dishes and store the dishes to be washed next in the washing chamber continuously and efficiently.
