FIG. 2 is a side sectional view of the main part showing a state in which the washing tub is drawn out of the main body of the washing machine before and after washing. 3 is a perspective view schematically showing a linear body holding device to be used, and FIG. 4 is a perspective view showing a hose holder as a holding member.

  As shown in the figure, an opening 1a is provided in the front surface portion (left side portion of the drawing) of the cleaning machine main body 1, and a cleaning tank 2 is provided so as to enter the cleaning machine main body 1 from the opening 1a. Yes. The upper part of the cleaning tank 2 is an opening 2a. And the guide rail 3 is being fixed to the outer surface of both the right-and-left both sides seeing from the front surface (left direction of a figure) of the washing tank 2, respectively. Moreover, the guide rail 4 is being fixed to the inner wall part of the right-and-left both sides seeing from the opening part 1a side of the washing machine main body 1. FIG. With these guide rails 3, 4, the cleaning tank 2 moves smoothly with respect to the cleaning machine main body 1 via a rotating roller (not shown).

  Further, a pump 5 that circulates cleaning water (not shown) stored in the cleaning tank 2 into the cleaning tank 2 and discharges it to the outside of the cleaning machine body 1 is fixed to the bottom of the cleaning tank 2. The pump 5 is fixed to the cleaning tank 2 by the fixing member 7 at the one end 6a side of the drainage hose 6 for discharging the cleaning water after the cleaning to the outside of the cleaning machine main body 1, and is drained after being guided by the hose holder 8. The hose 6 is drained to the outside through the other end 6b side. On the other hand, clean water is supplied from the outside of the washing machine main body 1 through the water supply valve 9 from the other end 10 b side of the water supply hose 10, guided by the hose holder 8, and fixed to the cleaning tank 2 by the fixing member 11. It is supplied into the cleaning tank 2 through the part 10a side.

  One end portion 8b side of the hose holder 8 is fixed to the inner back wall portion of the cleaning machine main body 1, and the other end portion 8a side is movable with respect to the sliding portion 21 fixed to the upper inner wall of the cleaning machine main body 1. The hose holder 8 is supported by its own weight by being fixed to the lower end portion of the piano wire 12 as a provided fishing support member.

  Tableware baskets 13a and 13b for holding tableware (not shown) are installed in the washing tank 2, and the washing water pressurized from the pump 5 is sprayed from the injection port 14a to the lower part of the tableware basket 13a. The rotating shower nozzle 14 is installed, and cleaning water is sprayed in various directions while rotating to clean the stored dishes. In addition, a heater 15 is disposed at the lower part of the cleaning tank 2, and cleaning water is appropriately heated during cleaning.

  A lock knob 16 for firmly fixing the cleaning tank 2 to the cleaning machine main body 1 is installed at a predetermined front portion of the cleaning tank 2. Further, by operating the lock knob 16, an upper lid (not shown) tightly seals the opening 2a of the cleaning tank 2 to prevent leakage of cleaning water during cleaning and steam during drying.

  In the first embodiment, the hose holder 8 as the holding member has a spiral shape like a mosquito coil as shown in FIGS. 3 and 4, and the flat portion is a holding portion 8 </ b> S of a linear body such as the hoses 6 and 10. Is forming. And the drain hose 6 and the water supply hose 10 are latched along the surface of the holding | maintenance part 8S. In addition, although the latching means of the drainage hose 6 and the water supply hose 10 with respect to the hose holder 8 is not illustrated for simplicity, it is not specifically limited, For example, it can be set as well-known arbitrary latching means.

  FIG. 4 shows only the hose holder 8 as a holding member. The hose holder 8 is a thin plate made of an elastic body such as resin or metal, but is not necessarily limited to a thin plate having a flat surface. For example, the holding portion 8S may be formed by forming fine corrugated ridges or irregularities along the spiral length direction.

  Next, the operation of the first embodiment configured as described above will be described. When the washing tank 2 is pulled out from the washing machine main body 1, the hose holder 8 is deformed as shown in FIG. 2, and the hose holder 8, the water supply hose 10, and the drainage hose 6 are drawn out together with the washing tank 2. Since the hose holder 8 has a spiral shape, the rigidity in the plane direction is secured to some extent, and the hose holder 8 is easily deformed in the normal direction of the plane (direction perpendicular to the surface of the plate). Since it deforms smoothly according to the amount and does not bend locally, the fixed water supply hose 10 and drainage hose 6 are similarly smoothly deformed, and a large bending stress is applied locally. There is no. At this time, the hose holder 8 has a planar shape and has no crossed portion, so that it does not get tangled or caught during deformation. Further, the piano wire 12 moves on the sliding portion 21 in the front-rear direction (left-right direction in the drawing) according to the moving amount of the cleaning tank 2 and supports the weight of the hose holder 8.

  When the cleaning tank 2 is stored from the state in which the cleaning tank 2 is pulled out, that is, the hose holder 8 is deformed, the hose holder 8 also starts to return to the original plate shape, and finally the rear of the cleaning tank 2 (State of FIG. 1). Here, the space in the operation direction of the washing tub 2 at the time of storage is about one plate thickness of the hose holder 8, the water supply hose 10 or the drainage hose 6 which is about the larger diameter, so that it can be stored compactly.

  As described above, according to the first embodiment of the present invention, the hose can be stored compactly without tangling or catching the hose when the cleaning tank 2 is stored / drawn, and the operation direction space of the cleaning tank 2 is increased. While spreading, a large bending stress is not locally applied, so that the effect of improving the durability of the hose can be obtained.

  In the first embodiment, both the water supply hose 10 and the drainage hose 6 are fixed to one hose holder 8, but similar effects can be obtained by fixing these hoses to individual hose holders. Needless to say.

Embodiment 2. FIG.
FIG. 5 is a perspective view showing the shape of the holding member 8 in the linear body holding device according to the second embodiment. In the first embodiment, the case where the holding member 8 is formed in a spiral shape corresponding to one round is shown. However, the holding member 8 has an inverted S-shape as shown in FIG. Even if it is configured in the same manner as in the first embodiment, it is flat and has no cross part, and since it is a thin plate, it is easily deformed in the direction perpendicular to the surface of the plate, that is, in the normal direction, and Since a large bending stress is not locally generated at the time of deformation, the same effect as in the first embodiment can be obtained.

  In the first embodiment, the input side and the output side of the hose approach each other, and one of the radii of curvature needs to be smaller than the other. In the second embodiment, the distance between the input side and the output side is increased. Since it becomes easy to expand, the degree of freedom of installation increases, and since it can be realized with the same radius of curvature, the durability of the hose can be further improved.

  By the way, in Embodiments 1 and 2, the washing machine body 1 side of the hose holder 8 is fixed and the washing tub 2 side is supported by the piano wire 12 as a fishing support member. Needless to say, the tank 2 side may be fixed and the washing machine main body 1 side supported by the piano wire 12.

Embodiment 3 FIG.
In the said Embodiment 1-2, the one end part of the hose holder 8 as a holding member is fixed inside the washing machine main body 1, and the other end part of the hose holder 8 is wash | cleaned by the piano wire 12 and the sliding part 21. The hose holder 8 is supported by its own weight so that it can be moved back and forth (left and right movement in the figure) according to the amount of movement. When both ends of the hose holder 8 are fixed using the hose holder 8 having a circumference of approximately one round (an angle of about 360 degrees) as shown in the first and second embodiments. Since the deformation amount in the normal direction of the hose holder 8 increases, the rigidity in the plane direction cannot be sufficiently secured, and the cleaning layer 2 is bent in the normal direction in a state of being pulled out, and is weak in repeated operations. End up.

  Therefore, in the third embodiment, the hose holder 8 has a length exceeding approximately one turn (approximately 360 degrees), that is, approximately N turns (approximately N turns, where N is an integer equal to or greater than 1) ( The one end of the hose holder 8 is fixed to the inside of the cleaning machine main body 1 using the not shown), and the other end is fixed to the rear end of the cleaning tank 2 (right side in FIG. 2). A drawer-type dishwasher constructed similarly was manufactured. With this configuration, the amount of deformation per circumferential length of the hose holder 8 can be smaller.

  As described above, according to the third embodiment of the present invention, the hose holder 8 is N-wrapped so that the rigidity of the hose holder 8 in the planar direction can be improved. It becomes possible to fix to the washing machine main body 1 and the washing tank 2, respectively. Further, this rigidity enhancement allows the hose holder 8 to withstand the dead weight of the hose, eliminating the need for the piano wire 12 and the sliding portion 21 as a fishing support member.

Embodiment 4 FIG.
FIG. 6 is a perspective view showing a holding member used in the linear body holding device according to Embodiment 4 of the present invention. In the first and second embodiments, the case where only one end portion of the hose holder 8 having a length of about one round is fixed, and in the third embodiment, the hose holder 8 having a length of about N rounds (N is more than 1). However, here, the hose holder 8 having a length of approximately (N + 1/2) circumference shown in FIG. 6 will be described. When considering the durability of the water supply hose 10 and the drainage hose 6, in addition to not applying a large bending stress to the operation of the cleaning tank 2, it is necessary to arrange the fixed hose piping as smoothly as possible. There is.

  Here, in the method of fixing both ends as shown in the third embodiment, it is necessary to determine the holder shape in consideration of the positional relationship between the hose fixing ends. For example, when the hose holder 8 shown in FIGS. 1 and 2 and the hose holder 8 shown in FIG. 3 is used, the drainage hose 6 enters the hose holder 8 from the inside of the washing machine body 1 from the bottom to the top. 8 exits from the top to the bottom and is fixed to the washing tank 2 and becomes a U-shape at the outlet of the hose holder 8. On the other hand, the water supply hose 10 enters the hose holder 8 from the bottom to the top from the inside of the washing machine body 1, exits the hose holder 8 from the bottom to the top, and is fixed to the cleaning tank 2, and the locus of the water supply hose 10 becomes smooth. .

  Accordingly, the hose holder 8 such as FIGS. 3 to 5 having a length of approximately N circumferences is suitable for the water supply hose 10, but the drainage hose 6 is not generally approximately N circumferences long, but generally ( The hose holder 8 having a length of N + 1/2) is good. Thus, by determining the peripheral length of the hose holder 8 from the relationship between the fixing positions of the water supply hose 10 and the drainage hose 6, a linear body holding device in which a smooth pipe line can be formed and the durability of the hose is improved, In addition, it is possible to obtain a drawer type cleaning apparatus using the same.

  In the above description, the case where the hose as the linear body is formed in approximately one turn, approximately N turns, or approximately (N + 1/2) turns is exemplified, but the present invention is not limited thereto, and the water supply hose 10 and the drainage are not limited thereto. Needless to say, if the hose 6 is smoothly piped, the same effect can be obtained even with a desired circumferential length that is easy to install. Further, the same effect can be expected if the shape is a spiral shape, a S shape (including an inverted S shape), or a smooth shape such as a loop shape or a spiral shape.

Embodiment 5 FIG.
In the first to fourth embodiments, the case where hoses such as the water supply hose 10 or the drainage hose 6 are used as the linear body has been described. However, the linear body is not necessarily a hose, for example, the pump 5 Needless to say, the present invention can also be applied to routing of a power cable to the heater 15 and a signal cable to the operation panel. Thereby, these cables are not entangled during the storing / drawing operation of the washing tank, and a highly reliable drawer type dishwasher can be provided.

  By the way, in the above description, the case where the linear body holding device of the present invention is used in a drawer type dishwasher has been described, but the linear body may be, for example, an electric wire, a wire, a rope, etc. in addition to a hose. Well, it can be widely used for the same application of repeatedly expanding and contracting these linear bodies. Moreover, although the case where the opening part 1a of the washing machine main body 1 exists ahead was demonstrated, this opening part 1a may be in any surface. In particular, when it exists above and below, the moving direction of the cleaning tank 2 is the direction of gravity, so the piano wire 12 and the sliding portion 21 are not necessary. Furthermore, although the case of the dishwashing apparatus was demonstrated, it cannot be overemphasized that the same effect can be anticipated except for tableware.

It is principal part side surface sectional drawing which shows the drawer-type dishwasher to which the linear body holding | maintenance apparatus by this Embodiment 1 and this linear body holding | maintenance apparatus are applied. It is principal part side sectional drawing which shows the state which pulled out the washing tank of the tableware washing machine shown in FIG. It is a perspective view which shows typically the holding | maintenance apparatus of the linear body of FIG.
