BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter for collecting garbage and a dishwasher equipped with the filter.

[0002]

2. Description of the Related Art A dishwasher has, for example, a configuration as shown in FIG. That is, a washing water tank 2 is provided at the bottom of the washing chamber 1, and a washing nozzle 3 and a rinsing nozzle 4 are rotatably provided at the bottom of the washing chamber 1. Here, the washing water sprayed from the washing nozzle 3 or the rinsing nozzle 4 is collected in the washing water tank 2 through the filter 5 that collects the garbage. The filter 5 is provided with a handle 5a for removing and carrying the residual vegetables. The handle 5a is formed by bending a metal plate into a U-shape as shown in FIG. To the filter 5. Here, since the filter 5 is interposed between the washing nozzle 3 and the washing water tank 2, the handle 5a is formed at a low height so that the rotation of the washing nozzle 3 is not hindered. And the interval between them was getting smaller.

[0003]

By the way, in order to carry the filter 5 of this type of structure, it is more convenient to raise the handle 5a and separate it from the bottom of the filter 5 in order to firmly grip the handle 5a. In this case, the overall height of the filter 5 is increased. In particular,
When mounted on a dishwasher, it is difficult to raise the handle 5a due to the washing nozzle 3 located above the filter 5, and the distance between the handle 5a and the bottom surface of the filter 5 is narrow. For this reason, there has been a problem that the handle 5a cannot be reliably gripped when removing or carrying the filter 5. In addition, when the handle 5a is raised from the bottom of the filter 5, the height of the filter 5 becomes large, so that a space for mounting the filter 5 as a dishwasher must be large, and the securing of other spaces is limited. There was also a problem that the degree of freedom in design was reduced.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a filter excellent in handling workability such as carrying and removing without increasing a height dimension, and to provide a filter mounting space. It is an object of the present invention to provide a dishwasher which can be reduced in size to secure another space.

[0005]

According to a first aspect of the present invention, there is provided a filter, wherein a handle is provided on a filter body so that the handle can be raised and lowered. The handle is provided at a position displaced in a horizontal direction from the center of gravity of the main body, and the handle is provided with a locking portion which comes into contact with the filter main body on the side opposite to the center of gravity when the filter main body is in an upright state. I do.

According to a second aspect of the present invention, there is provided a dishwashing machine provided with a filter for collecting garbage at the bottom of the washing room, wherein the filter is capable of raising and lowering a handle on a filter body. The center of rotation of the handle is located at a position displaced in the horizontal direction from the center of gravity of the filter body, and when the handle is in an upright state with respect to the filter body, the filter is located on the side opposite to the center of gravity. It is characterized in that a locking portion abutting on the main body is provided.

[0007]

According to the first aspect of the present invention, since the handle is provided so as to be able to move up and down, when the handle is not used, the size of the handle protruding above the filter can be reduced by lowering the handle. Also, when carrying, the handle is turned to be in an upright state. Then, the space between the filter main body and the handle can be made sufficiently wide, and the space can be easily put in, so that it is easy to hold. When the handle is in the upright state, the center of rotation of the handle is displaced in the horizontal direction from the center of gravity, so that the load on the filter body generates a moment about the rotation axis toward the center of gravity. Therefore, the filter body receives a rotational force about the rotation axis toward the center of gravity, and is pressed against and held by the locking portion on the side opposite to the center of gravity. Therefore, the filter body is maintained in a stable posture even when the handle is lifted.
There is no wobble with carrying.

Further, according to the configuration of claim 2, claim 1 is
Since the filter is used, not only is the filter easy to handle, but also the filter can be made thin, and the filter mounting space of the dishwasher can be reduced.

[0009]

As described above, according to the first aspect of the present invention, when the handle is turned down, the height of the filter can be reduced, so that a thin filter can be realized. On the other hand, when the handle is in the upright state during removal or carrying, the filter body is pressed against the locking portion and the posture is stably supported. For this reason, a sufficient interval between the filter main body and the handle can be ensured, the filter main body is easy to hold, and the filter main body is supported in a stable state without tilting even if the handle shakes with carrying. In this way, the thin structure,
This provides an excellent effect that both improvement in handling workability such as removal and carrying of the filter can be achieved. Further, according to the invention of claim 2, the space for mounting the filter can be narrowed while the handling workability is excellent, so that the other space constituting the dishwasher can be sufficiently secured and used effectively. It has an excellent effect that the degree of freedom in designing a dishwasher is expanded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the present invention will be described in detail with reference to the drawings. First Embodiment First, a dishwasher will be described with reference to FIG.
The dishwasher 10 includes a dishwashing tank 12 inside. Tableware (not shown) is accommodated in the dishwashing tank 12.
The washing water tank 14 provided at the bottom stores washing water in which warm water supplied from a water supply pipe (not shown) and a detergent are mixed. The washing water tank 14 has a shape with a shallow bottom but a large surface area in order to secure a sufficient amount of water. The washing pump 16 is provided on the bottom side of the dishwashing tank 12, sucks washing water through a filter 18 for collecting garbage disposed between the dishwashing tank 12 and the washing water tank 14, and is not shown. The cleaning water is pressure-fed to the rotating cleaning nozzles 21 and 23 via a circulation pipe, and the cleaning water is sprayed onto tableware (not shown) to perform cleaning.

Next, the filter 18 of the first embodiment will be described. As shown in FIG. 2, the filter 18 includes a flat plate-shaped filter body 20 having a plurality of holes in the bottom surface, a pair of left and right rotation shafts 22 rotatably mounted on a side plate of the filter body 20, and a rotation shaft. It comprises a rod-shaped stopper 24 protruding from the rotation shaft 22 and a handle 26 which is a U-shaped round bar bridged between the rotating shafts 22 and which can be turned up and down. As shown in FIG. 3, the rotation shaft 22 is provided at a position displaced from the position of the center of gravity of the filter main body 20 by a distance L in the horizontal direction. Further, as shown in FIG. 4, the stopper 24 protrudes on the opposite side to the center of gravity,
With the handle 26 upright, the bottom portion 20 of the filter body 20 is
a. As shown in FIGS. 2 and 3, the handle 26 is provided with a V-shaped bent portion 28 at a substantially central portion thereof. The handle 26 comes into contact with the bottom portion 20a of the filter body 20 and the handle 26 is folded down. 26 is raised slightly above the bottom 20a.

The filter 1 attached to the dishwasher 10
To remove and clean 8, do the following: First,
The washing nozzle 21 and the rinsing nozzle 25 from the position shown in FIG.
Is rotated 90 degrees. Then, nothing blocks the upper part of the filter 18. In this state, the handle 26 and the stopper 24 are connected to the filter body 20 as shown in FIG.
And the handle 26 is in the bent portion 2
8 is slightly raised by the contact with the bottom 20a. As described above, since the handle 26 is stored in the filter main body 20 when the handle 26 is tilted, the thickness of the filter 18 is equal to the thickness of the filter main body 20 and is thin. Next, a hand is inserted from above the filter 18, and the handle 26, which is slightly raised by the bent portion 28 and is easy to put in the hand, is set up. Then, a sufficient space is created between the handle 26 and the filter body 20, so that the handle 26 can be firmly grasped by hand.
Thus, the filter 18 is removed from the dishwasher 10 by grasping the handle 26 and pulling it upward.

When the filter 18 is lifted upward while holding the handle 26 in the upright state, the rotating shaft 22
Is provided at a position displaced in the horizontal direction from the center of gravity of the filter body 20, so that the filter
There is a moment about 2 about to rotate toward the center of gravity. However, the stopper 24 is located on the opposite side of the center of gravity
Is projected, the bottom portion 20a of the filter body 20 is pressed against the stopper 24 from below, the rotation is stopped, and the state shown in FIG. 4 is obtained. Therefore, the filter body 20 can be supported in a stable posture without being tilted by the handle 26 in the upright state. Also, since the bottom 20a of the filter body 20 is pressed against the stopper 24,
Even when the filter 18 is carried, the posture is stable and does not fluctuate.

As described above, according to the first embodiment, when the handle 26 is tilted, the thin filter 1
On the other hand, in the case of removing or carrying the filter 18, when the handle 26 is in the upright state, the bottom portion 20a of the filter body 20 can contact the stopper 24 and be supported in a stable posture. The distance between the handle 20 and the handle 26 can be made sufficiently large, and it is convenient to carry. As described above, according to the filter 18 of the present embodiment, it is possible to achieve both reduction in thickness and improvement in handling workability. Further, in the present embodiment, in particular, since the handle 26 is provided with the bent portion 28 so as to be raised slightly in a state where the handle 26 is lowered into the filter main body 20, the operation of raising the handle 26 to the upright state becomes easy. Further, when the handle 26 is tilted into the filter main body 20, the thickness of the filter 18 can be made as thin as the thickness of the filter main body 20, so that the filter 18 can be mounted in a vertically thin space in the dishwasher 10. For this reason, a sufficient space can be secured in other portions such as reducing the depth of the washing water tank 14 to provide a hot water storage tank below the washing water tank 14 or increasing the capacity of the dishwashing tank 12. The degree of freedom in designing is increased. Note that the stopper 24 may be screwed and fixed to the rotating shaft 22 or may be fixed by welding. Also, the rotating shaft 2
The handle 28 may be fixed by welding, or the rotating shaft 22 and the handle 28 may be integrally formed by bending a round bar.

<Second Embodiment> In the first embodiment, the handle 26 and the stopper 24 are constituted by separate members made of round bars. However, for example, as in the second embodiment shown in FIG. 36 and stopper 3
4 can also be formed integrally by bending a sheet metal into a U-shape. With this configuration, processing becomes easy.

<Third Embodiment> The shape of the handle can be variously modified. For example, as in a third embodiment shown in FIG. 6, a single plate-shaped handle 46 and a stopper are integrally formed. 44 and a pair of L
It is also possible to adopt a configuration in which it can be pivoted up and down around a rotation shaft 42 fixed to the bottom 20a of the filter body 20 by means of a V-shaped fitting 48. Also in this case, if the rotating shaft 42 is displaced in the horizontal direction from the center of gravity of the filter main body 20, the stopper 44 is
By contacting Oa, the filter 18 can be supported in a stable state.
