Embodiment 1

[0036] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the same code|symbol is attached|subjected to the member of the same structure as a conventional example, and the description is abbreviate|omitted.

[0037] Such as figure 2 as well as image 3 As shown, inside the cleaning tank 4, when viewed from the front, a cleaning nozzle 14 is provided on the left side, a cleaning nozzle 15 is provided on the right side, and a cleaning nozzle 16 is provided on the rear side. A switching valve 17 is provided between these washing nozzles 14 to 16 and the washing pump 8 . The switching valve 17 is switched sequentially so as to pass the water pressurized by the washing pump 8 through any one to two of the washing nozzles 14 to 16 .

[0038] Second, use Figure 1 to Figure 7 The switching valve 17 will be described.

[0039] The water passage portion 18 connects an inlet 19 through which water pressurized by the w...

Embodiment 2

[0078] Next, another example will be used to describe the embodiment of the present invention in more detail. In addition, the same components as those already used in Embodiment 1 or the prior art will be described using the same symbols or drawings.

[0079] Such as Figure 9 As shown, the dish washer of embodiment 2 has a cleaning tank 4. Viewed from the front, a cleaning nozzle 14 is provided on the left side in the cleaning tank 4, a cleaning nozzle 15 is provided on the right side, and a cleaning nozzle 15 is provided on the back side. Nozzle 16. A switching valve 17 is provided between these washing nozzles 14 to 16 and the washing pump 8 . The switching valve 17 is switched sequentially so as to pass the water pressurized by the washing pump 8 through any one to two of the washing nozzles 14 to 16 .

[0080] and figure 2 The dishwasher of the illustrated embodiment 1 differs in that there is no pump control 40 . Since the operation of the closing member 21 and th...

Embodiment 3

[0090] Next, another example is used to describe the implementation of the present invention in more detail. In addition, the same reference numerals or drawings will be used to describe the same components as those already used in Embodiment 1, 2 or the prior art.

[0091] Such as Figure 11 As shown, a flat elastic member 25 is fixed on the surface of the blocking member 21 in contact with the opening surface 30 , and a gap 35 is provided on the back surface of the elastic member 25 and the facing portion of the blocking member 21 . That is, the buffer mechanism for alleviating the impact caused when the closing member 21 blocks the outlet 20 is composed of the elastic member 25 and the space 35 . The gap 35 is provided facing the auxiliary rib 32 which is a part of the opening surface 30 constituting the outlets 20a to 20d. Other structures are the same as in the second embodiment.

[0092] Next, the operation of the dishwasher of the third embodiment will be described. ...

Abstract

The dishwasher in accordance with the present invention comprises a switch valve arranged in a water passage connecting between a washing pump and a plurality of washing nozzles, and is characterized in that the switch valve comprises a waterway section and a lock-out member. The waterway section connects an inlet port for water pressurized by the washing pump and an outlet port. The lock-out member takes reciprocal movement within the waterway section. In addition, the dishwasher comprises impact-buffering means for buffering impact between the lock-out member and the output port. With such an arrangement, the dishwasher in accordance with the present invention realizes a switch valve that can be constructed with a simple structure with reduced switching noise and allows water to be selectively ejected from a plurality of washing nozzles with one single washing pump whereby low noise and saving of water can be realized without increasing costs or enlarging the overall size of the dishwasher.

Description

technical field [0001] The present invention relates to a dishwasher for washing dishes by spraying water pressurized by a washing pump from a plurality of washing nozzles. Background technique [0002] use Figure 13 as well as Figure 14 A conventional dishwasher will be described. [0003] The water supply path 1 supplies tap water to the main body 2 of the dishwasher, and the water supply is controlled by the water supply valve 3 . The dishwasher main body 2 includes a washing tank 4 having a water storage 5 storing supplied water, and a water level sensor 6 communicating with the water storage 5 . [0004] The water stored in the water storage unit 5 is heated by the heater 7 and simultaneously pressurized by the cleaning pump 8, and is sprayed from a plurality of cleaning nozzles 9 to the tableware placed in the tableware basket 10 to clean the tableware. The drain pump 11 drains the water in the cleaning tank 4 . [0005] The dishwasher main body 2 has a front doo...
