Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cleaning machine that cleans objects to be cleaned by spraying cleaning liquid.

Conventional Structure and Problems Conventionally, in this type of washing machine, as shown in Fig. 1, there is a washing tank 1 that accommodates the objects to be washed, and the washing tank 1 is rotatably driven by hydraulic power to apply cleaning liquid to the objects to be washed. There are spray nozzles 2 and 3 and a pump 4, and the cleaning liquid is applied to the object to be cleaned while circulating the cleaning liquid, and dirt is removed by its chemical and mechanical power.

Further, 5 is a heater for heating the cleaning liquid or rinsing water, and 6 is a storage basket in which the items to be cleaned are placed. 7 is a pump for drainage.

Conventionally, in a cleaning machine with such a configuration, as shown in Fig. 1, cleaning liquid is jetted out from several jetting ports provided in nozzles 2 and 3, and the nozzles are rotated by this jetting force, so that the cleaning tank is filled with water. It is constructed so that the cleaning liquid hits all of the objects to be cleaned stored in the storage basket 6 in the storage basket 1. Therefore, if the amount of objects to be cleaned is less than the predetermined amount, the amount of cleaning liquid will be wasted.
In addition, even if the amount of the object to be cleaned is extremely small compared to the specified amount, it is cleaned in the same way, so the cleaning liquid is used unnecessarily and the cleaning time also takes the same amount of time, which is a huge waste of energy. It was supposed to be washed.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a washing machine that can wash items according to the amount of objects to be washed.

Structure of the Invention The cleaning machine of the present invention includes a cleaning tank that stores a plurality of cleaning items, a support basket for the cleaning items, a circulation pump that circulates the cleaning liquid, and a nozzle body that is rotationally driven and sprays the cleaning liquid from a group of injection ports. The nozzle body is rotatably connected to the cleaning liquid path, and the nozzle body is divided into two by the path, and the inside of this path is partitioned into two paths up to the nozzle body, The two passages are provided with holes, each of which faces into the two divided nozzle bodies, and a switching means for opening and closing one of the two passages is interposed.

Further, the injection port group of the nozzle body is divided into the rotation center side of the nozzle body and its outer circumferential side, and paths for the cleaning liquid reaching the two divided injection port groups are formed separately. A switching means for opening and closing one of the cleaning liquid paths is interposed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 and 3, there are a cleaning tank 8 for storing objects to be cleaned, and a storage basket 9 for setting the objects to be cleaned in the cleaning tank 8. Nozzle body 10 that is rotationally driven by the propulsive force of water (arrow a)
(There is also an upper stage, but not shown) and a plurality of spout ports 11 for spouting cleaning liquid are provided on the upper surface thereof. Reference numeral 12 denotes a circulation pump, which draws in the cleaning liquid stored at the bottom of the cleaning tank 8 through a path 13, and
4 and 15. A switching means 16 such as a valve is provided in the middle of the path 14 and is connected to paths 17 and 18, and the path 17 is connected to an upper nozzle body (not shown). The portions of the paths 15 and 18 that protrude into the cleaning tank 8 are composed of cylindrical pipes separated by partitions 19.
Hole 2 for sending cleaning liquid to nozzle body 10 at 18
0 and 21 are provided, and also serves as the rotation axis of the nozzle body 10. The path 15, the hole 20, the paths 14, 18, and the hole 21 constitute a path for uniformly cleaning the objects stored in the entire area of the cleaning tank 8, and the path 15 and the hole 20 are used to clean the objects stored in the entire area of the cleaning tank 8. It is configured for the area. Further, 22 indicates the nozzle body 10 at the protruding portion of the paths 15 and 18 through which the nozzle body 10 rotates.
The sliding material provided inside serves as a seal that partitions the inside of the nozzle body 10 into right and left sides.
Reference numeral 23 denotes a stopper for preventing the nozzle body 10 from floating up, and is attached to the protruding portions of the paths 15 and 18. 24 is a drain pump, and 25 is a heater for warming the cleaning liquid.

To explain the operation in the above configuration, first, when the object to be cleaned is a predetermined amount, when the switching means 16 is opened, the cleaning liquid is force-fed to all the paths 14, 15, 17, and 18, The cleaning liquid is ejected from all the spouts provided in the container (the same applies), and all the stored objects to be cleaned can be washed with the cleaning liquid. In addition, in the case of washing a small amount, by closing the switching means 16, the washing liquid is transferred to the path 1.
5 will be sent under pressure. Then, since the cleaning liquid is sent only from the hole 20 provided in the path 15, the cleaning liquid is always supplied to only one side of the nozzle body 10, and while the nozzle body 12 rotates in the range W in FIG. Only the spout 11 of the nozzle body 10
Cleaning liquid is sprayed from the Therefore, only a small amount of objects to be cleaned within this range of the cleaning tank 8 will be cleaned. In this case, since the same circulation pump 12 as used for whole washing is used for pressure feeding, the jetting pressure of the washing liquid increases as the flow rate decreases, and the object to be washed can be washed with much stronger force than when washing the whole body. Therefore, the time required for cleaning can be shortened, and there is no need to use unnecessary power. In addition,
The rotation of the nozzle body 10 is performed by the reaction of the ejection force a.

Figures 4 and 5 show embodiments of the present invention, in which the inside of the nozzle body 10 is divided by a partition 19, and the inside of each nozzle body 10 is configured to be connected to paths 15 and 18. In the case of , the jet is made to come out only in the area of the central part W (the same is true even if only on the outside); in this configuration, the nozzle body 10 is completely partitioned, so sliding materials, sealing materials, etc. are especially required. It disappears. Note that the same parts as in FIGS. 2 and 3 are given the same reference numerals.

Effects of the Invention As is clear from the above embodiments, the washer of the present invention is capable of washing different items depending on the amount of items to be cleaned using a single washer. It eliminates the burden on the user of washing the water by storing it until it becomes dry, and it is possible to wash even a small amount immediately.In this case, the washing power is stronger, and the washing can be done in a short time and at low cleaning costs, making it economical. Moreover, it is easy to use. Moreover, if there are many objects to be cleaned, by switching the switching means, the entire group of injection ports of the nozzle body can be used for efficient cleaning.
