Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dishwasher with a rotary nozzle.

[0002]

[Prior Art]

 In a dishwasher, washing and rinsing are generally performed by a rotating washing nozzle or rinsing nozzle, and a supporting structure for the washing nozzle or rinsing nozzle is known from Japanese Utility Model Publication No. 3-33321.

That is, a cleaning nozzle is rotatably supported by a nozzle bearing having a water passage in an inner hollow portion, a sliding ring is interposed between the nozzle bearing and the cleaning nozzle, and a cap is used as a nozzle bearing. It is a mated configuration.

[0004]

[Problems to be solved by the device]

 However, here, due to the structure, the nozzle bearing and the cleaning nozzle have a slight gap in the rotary sliding portion. Therefore, during cleaning, water leaks from this gap and jumps out vigorously. Such leaked water adversely affects the cleaning or rinsing effect.

Next, this point will be described with reference to FIG. Reference numeral 1 denotes a rinsing nozzle which is horizontally rotatably arranged in the washing chamber, has a hollow interior, and has a plurality of injection ports 2. Reference numeral 3 denotes a nozzle supporting portion that rotatably supports the rinse nozzle 1, which is formed in a hollow shape, and therefore the inside of this hollow is used as a water passage 4 for the rinse water pumped by a pump. Communication ports 5 are formed on the side surfaces of the rinse nozzle support portion 3 in some places to allow rinse water to pass from the nozzle support portion 3 to the rinse nozzle 1.

The rinse nozzle 1 is rotatably supported by the nozzle supporting portion 3 via a fitting portion 6 at the center thereof, but this fitting portion 6 is provided so as to smoothly rotate and slide between both portions. A ring bush made of synthetic resin or the like is used. Reference numeral 7 is a nozzle retainer, and is attached and fixed to the head surface of the nozzle support portion 3 with screws 8, 8.

The thrust load in the vertical direction generated when the rinse nozzle 1 rotates is received by the nozzle retainer 6 and the collar portion 9 provided on the nozzle support portion 3. Here, a slight gap 10 is present in the sliding surface between the fitting portion 6 of the soot nozzle 1, the nozzle support portion 3 and the nozzle retainer 7, and the nozzle retainer 6 and the rinse nozzle of the gap 10 are included. The gap formed between the first fitting portion 6 and the first fitting portion 6 is opened in the lateral direction.

Therefore, when the rinsing nozzle 1 rotates and the water jetted from the jet port 2 is used to wash the dishes stored in the washing chamber, a part of the rinsing water flowing as indicated by the solid line arrow is in this gap. Leaks and water leaks laterally as shown by the dotted arrows. Then, this laterally scattered water is orthogonal to the rinse water (one-dot chain line arrow) that goes upward from the injection port 2 of the rinse nozzle 1 (upright direction), so that the rinse water is prevented from being sprayed and the rinse effect is obtained. Will drop.

The present invention has been made in view of the above points, and provides a rotary rinse nozzle designed so that leaked water is discharged so as not to interfere with the rinse water and can be used as rinse water. Is provided.

[0010]

[Means for Solving the Problems]

 The present invention is provided with a hollow nozzle support portion for passing rinse water, and a hollow portion which is rotatably mounted horizontally on the nozzle support portion and communicates with the hollow portion of the nozzle support portion. In addition, in a dishwasher having a rinse nozzle having a plurality of injection ports and a nozzle retainer that is attached and fixed to the end of the nozzle support portion and presses the rinse nozzle, a fitting in which the nozzle support portion is fitted. And a gap formed between the nozzle support portion and the fitting portion, and through the gap, the leaked water from the gap is jetted out in the substantially same direction as the jet direction of the cleaning water of the nozzle. It is equipped with a waterway.

[0011]

[Action]

 A water channel that opens vertically is provided in communication with the gap formed between the fitting portion of the rinse nozzle that is horizontally rotatably attached to the nozzle support portion and the nozzle support portion. Therefore, even if a part of the rinse water leaks from the gap, the leaked water jumps out in the same vertical direction as the water sprayed from the rinse nozzle. This prevents the rinsing water from being obstructed unlike the conventional leaked water that leaks sideways, and prevents the rinsing effect from decreasing. Moreover, it can also be used as rinse water by letting leaked water jump out in the vertical direction.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The same or equivalent components as those of the conventional device shown in FIG. 3 are designated by the same reference numerals. FIG. 1 is a schematic structural diagram of a dishwasher. A washing chamber 13 is provided inside a main body 12 of the dishwasher, and a washing nozzle 14 and a rinsing nozzle 1 are provided above and below the washing chamber 13. Are arranged in pairs one by one. A cleaning pump 15 supplies the cleaning water to the upper and lower cleaning nozzles 14 and is guided to the upper cleaning nozzle 14 through common water conduits 16a and 16b for rinsing water. The wash water is circulated and supplied.

A rinsing pump 17 receives water from a water source and sends the water to the upper and lower rinsing nozzles 1 via common water conduits 16 a and 16 b. A cleaning nozzle shaft 18 has a structure in which an inner pipe and an outer pipe are integrally formed. Rinse water passes through the inner pipe and flows to the water passage 4 of the nozzle support portion 3. On the other hand, the cleaning water passes through the outer pipe and is sprayed from the spraying unit 14a of the cleaning nozzle 14.

Next, the structure of the support portion of the rinse nozzle 1 according to the present invention will be described with reference to FIG. A circular recess 20 is formed on the end surface of the fitting portion 6 of the soot nozzle 1 with the nozzle support portion 3. Then, the nozzle retainer 7 is housed in the circular recess 20 and fixed to the nozzle support portion 3 with screws 8, 8. Then, between the nozzle retainer 7 and the circular recess 20, a narrow water passage 21 communicating with the gap 10 and opening in the vertical direction is formed.

Therefore, when a part of the rinse water leaks out from the gap 10, the leaked water is temporarily directed to the horizontal direction and then to the vertical direction in the groove 21 at the circular recess 20 and finally to the vertical direction. Pops out. As a result, the leaked water is scattered in parallel with the rinse water, which does not hinder the rinse water. Further, in the prior art, with respect to the tableware placed at the position which is the rotation center of the rinsing nozzle 1, since the amount of washing water directly subsided is not so large, it is placed at this position. The dishes could not be washed well. However, in the present application, the leaked water can be used as rinse water for the dishes placed at the center of rotation by ejecting the leaked water from a position near the center of rotation of the rinse nozzle 1, and good cleaning can be performed. Is possible. Therefore, the leaked water can be effectively used. However, if the spouting position of the leaked water is too close to the center of rotation, the cleaning effect will be diminished, so a certain interval is required.

[0016]

[Effect of the device]

 As described above, according to the present invention, the structure in which the rinsing nozzle is pivotally supported by the nozzle support, and the rinsing nozzle is supported by the nozzle retainer so that the rinsing nozzle is supported so as to be horizontally rotatable, is improved. A water channel was created to vertically scatter water leaking from the gap between the rotating and sliding parts. As a result, the leaked water is in the same direction as the rinse water that emerges from the nozzle of the rinse nozzle, and does not scatter laterally like conventional leaked water, so it does not hinder the spray of the rinse nozzle and does not only reduce the rinse effect. Without spilling water, you can also use yourself as rinsing water, it is not wasted and the rinsing effect is improved.
