The present invention relates to a dish washer for cleaning dishes by spraying the washing water to the dishes accommodated in the cleaning tank.

BACKGROUND ART Conventionally, a general household dishwasher is used for cleaning by spraying washing water onto objects to be cleaned, such as dishes listed in a dish container provided in a washing tank. At this time, the arrangement of the injection unit for injecting the washing water is an important point so that the washing water is evenly sprayed on a plurality of wash objects listed in the dish container. In particular, when the dish container is provided in multiple stages so as to accommodate a large number of objects to be washed in the washing tank, the washing water needs to be evenly sprayed on the objects to be disposed in the dish containers at each stage. However, the washing water sprayed from below to the to-be-cleaned object accommodated in the table top arrange | positioned at the upper end becomes the to-be-cleaned object obstacle listed at the bottom, and wash water does not fully spread evenly. As a result, the cleaning ability with respect to the to-be-cleaned object accommodated in the upper end falls.

In order to solve this problem, the dishwasher which arrange | positioned the some injection part so that the washing water can be sprayed to the to-be-cleaned object from the multi direction in a washing tank is known. However, in order to be able to inject washing water from a plurality of spraying portions, it is necessary to increase the amount of water supplied to the washing tank. Therefore, the heating time for heating the washing water is long, and the operating time and power consumption increase. In addition, it is necessary to increase the size of the cleaning pump because the amount of water used increases. As a result, it not only leads to an increase in cost, but also causes problems such as an increase in noise and vibration caused by using a large amount of washing water.

Thus, a dishwasher has been developed in which a water supply amount does not increase even when a plurality of injection parts are provided to improve the washing ability, and such a problem does not occur. For example, there is one disclosed in Japanese Patent Application Laid-Open No. 2004-267661.

Fig. 6 is a front view showing the construction of a conventional dish washer of this kind. In FIG. 6, rotary cleaning nozzles 101 and 102 are disposed below the cleaning tank 106 as a plurality of injection units. In addition, a fixed cleaning nozzle 103 is disposed on the rear wall of the cleaning tank 106. The washing water pressurized by the washing pump 104 is sequentially switched by the water fountain device 105 to each of these washing nozzles 101, 102, and 103. Therefore, the washing water is sprayed onto the plurality of objects to be cleaned 107 without increasing the water supply amount.

However, in such a conventional dishwasher, when the object to be cleaned 107 disposed on the upper end is washed with washing water from the fixed washing nozzle 103, the fixed washing nozzle 103 touches the washing water outside a certain range. Can't. Therefore, there is a problem in that the washing water cannot be uniformly applied to the shapes and installation postures of various dishes, and sufficient washing performance cannot be obtained.

The dish washing machine according to the present invention includes a washing tank having an opening in the front surface, a dish container disposed in the washing tank, a plurality of spraying portions for spraying washing water into the object to be stored for each dish, and a plurality of spraying portions for washing water. It includes a pump device for supplying. At least any one of the plurality of injection units includes a rotary cleaning nozzle and a fixed cleaning nozzle communicating with each other.

Thereby, the location where the various dishes are placed in a dish container is wash | cleaned with a rotating washing nozzle. On the other hand, about the location where the kind and installation attitude of a tableware were determined to some extent, it wash | cleans with a fixed washing nozzle.

In this way, the dishwasher of the present invention can provide a dishwasher that achieves both improved washing performance and space saving by properly combining the rotary washing nozzle and the fixed washing nozzle.

The energization control, the drive control of the blower in the drying step, and the like are performed by a controller (not shown) provided in the main body 1 of the dish washing machine.

Fig. 3 shows a state in which the lower dish container 8 and the upper dish container 9 are taken out from the washing tank 2 as viewed from the front side, and the fixed washing nozzle 5 and the fixed washing nozzle are shown in FIG. The form of the rotary cleaning nozzle 7 in communication with (5) is shown clearly.

In Fig. 3, the fixed cleaning nozzle 5 is formed approximately in a cross shape by the vertical portion 5a and the horizontal portion 5b formed in a flat cylindrical shape, and the lower end of the vertical portion 5a is connected to the fountain portion 15. Connected. The horizontal part 5b respond | corresponds that the upper side dish container 9 is formed in the shape which formed the step | step with which height differs from side to side, and the horizontal part 5b differs in height position from side to side.

Further, a rotary washing nozzle raceway 6 extending forward from the fixed washing nozzle 5 is connected to the left side of the horizontal portion 5b. In addition, as the distal end portion of the rotary washing nozzle raceway 6, the rotary washing nozzle 7 is disposed near the lower center of the left side of the upper dish container 9.

The rotary washing nozzle raceway 6 is connected to the fixed washing nozzle 5 in a detachable manner. That is, the rotating washing nozzle 7 is detachably connected to the fixed washing nozzle 5 and is connected to the washing water so as to communicate with it. Therefore, in the case of storing a high-level dish or the like on the left side of the lower dish container 8, the installation of the object to be cleaned 10 to the lower dish container 8 is removed by removing the rotary washing nozzle raceway 6. It can increase.

The rotary washing nozzle raceway 6 has a substantially hollow cylindrical shape, and four click portions 60a are provided at the outer periphery of one end at every 90 degrees. On the other hand, four groove portions 50a corresponding to the click portion 60a are arranged at the connection portion of the fixed cleaning nozzle 5. After inserting the click part 60a and the groove part 50a by the position from the front, it rotates about 15 degrees to the right direction, and the projection 60b engages and fixes by passing over the processus 50b, and the rotary washing nozzle raceway (6) and the fixed washing nozzle 5 are connected in watertight manner.

In the horizontal part 5b of the fixed washing nozzle 5, a plurality of washing water injection holes 20b for injecting washing water into the object to be cleaned 10 accommodated in the upper dish container 9 are opened. The washing water injection port 20b sprays the washing water upwards toward the inner surface of the object to be cleaned 10 accommodated in the upper dish container 9. In addition, the washing water injection port 20a is opened above the vertical portion 5a. The washing water injection port 20a injects washing water in a fan shape in a substantially horizontal direction.

In addition, each of the plurality of washing water injection holes 20b provided in the horizontal portion 5b does not necessarily spray washing water upwards, but, for example, washing water jet ports close to the receiving place such as chopsticks or spoons are washed sideways. The water may be sprayed, and the washing water may be sprayed mainly on chopsticks or spoons that are hard to fall off. In addition, when the upper dish container 9 does not have a level | step difference, the horizontal part 5b does not need to be formed in the shape which differs in height position from side to side.

In the upper surface of the rotary washing nozzle 7, a plurality of washing water injection holes for spraying washing water from below are opened in the object to be cleaned 10 accommodated in the left side of the upper dish container 9. Thereby, the washing water can be sprayed directly from the bottom to the to-be-cleaned object 10 accommodated in the left part of the upper side dish container 9, and it can wash | clean evenly also about the shape and installation posture of various tableware.

At the portion where the vertical portion 5a and the horizontal portion 5b of the fixed cleaning nozzle 5 intersect, and at the portion where the horizontal portion 5b of the fixed cleaning nozzle 5 and the rotary cleaning nozzle raceway 6 intersect, The inside of the cylinder is in communication. Thereby, the washing | cleaning water supplied from below the vertical part 5a is supplied to the vertical part 5a, the horizontal part 5b, and the rotating cleaning nozzle channel 6, and it is comprised so that each washing | cleaning water may be sprayed from an injection port. The fixed cleaning nozzle 5 is formed in a flat cylindrical shape, so that it does not protrude from the rear wall of the cleaning tank 2 to reduce the accommodation space of the object to be cleaned 10.

In addition, since the washing water injection port 20a provided in the vertical portion 5a injects washing water in a substantially horizontal fan shape, the washing water is discharged from above the object to be cleaned 10 contained in the washing tank 2. I can touch it. Thereby, the upper surface part of the to-be-cleaned object 10 which is hard to be wash | cleaned with the wash water sprayed from below which is the main body of washing water injection can be wash | cleaned. In particular, a dish with a bottom, such as a to-be-washed object 10 with a rim at the bottom, for example, a mug 10a shown in FIG. 1, is likely to leave residues in the bottom. The washing water is injected into the tableware from above to wash away the residue, and the effect of washing water evenly on all surfaces is obtained.

In addition, the rotary washing nozzle raceway 6 has a cylindrical shape, thereby eliminating adhesion of water droplets to the upper surface and improving drying performance.
