Embodiment 1

[0053] Such as Figure 1-Figure 7 As shown, the present embodiment provides a water separating device for a dishwasher, which includes a connected first housing 91 and a second housing 101, and a water dividing chamber is formed between the first housing 91 and the second housing 101. 2. The water diversion chamber 2 is provided with a rotatable water diversion paddle 11, and the second housing 101 is provided with a plurality of spray outlets 6, and the water diversion paddle 11 is provided with a through hole 12, and the through hole 12 is aligned with a single or multiple spray outlets 6 to lead to the corresponding spray outlets 6, and the water diversion plate 11 and the second housing 101 are provided with positioning holes for positioning the through holes 12 and the spray outlets 6. detection device.

[0054] The water distribution device of the dishwasher can be arranged at the bottom of the dishwasher, and the washing pump at the bottom of the dishwasher will pump w...

Embodiment 2

[0095] Such as Figure 1-Figure 18 As shown, this embodiment is a further limitation of the first embodiment, the first housing 91 is provided with a water inlet 3 and a water outlet 5, and the water inlet 3 and the water outlet 5 are connected with the water separation chamber 2 In communication with each other, the water flows into the water separation chamber 2 through the water inlet 3 and is led out by the water outlet 5 and / or the spray outlet 6 .

[0096] The water dividing device of a general dishwasher only has a water inlet 3 and a spray outlet 6. The washing pump at the bottom of the dishwasher pumps water to the water inlet 3, and the water enters the spray inside the dishwasher from the spray outlet 6. device. When heating the washing water or recovering the washing water, additional pipelines and control valves need to be installed, which not only increases the cost, but also makes the internal pipelines of the dishwasher complicated and inconvenient to maintain...

Embodiment 3

[0116] Such as Figure 13-18 As shown, this embodiment is a further limitation of Embodiment 1 or Embodiment 2, providing several specific ways of setting the spray outlet 6 and water diversion paddle 11 on the second housing 101, as well as specific positioning detection parts 19 and the arrangement manner of the sensing element 20, take the manner with three spray outlets 6 as an example.

[0117] In this embodiment, the spray outlet 6 includes the first spray outlet 13, the second spray outlet 14 and the third spray outlet 15 arranged on the second housing 101, and a certain distance between adjacent spray outlets 6 is maintained. When the water diversion paddle 11 rotates and the through hole 12 is opposite to one or two of the spray outlets 6, the corresponding spray outlet 6 is conducted;

[0118] Preferably, the axes of the first spray outlet 13 , the second spray outlet 14 and the third spray outlet 15 are arranged in parallel.

[0119] The first spray outlet 13, the...

Abstract

The invention belongs to the field of a dish washing machine, and discloses a water distribution device of a dish washing machine, the dish washing machine and a control method thereof, wherein the water distribution device comprises a first shell and a second shell which are connected with each other; a water distribution cavity is formed between the first shell and the second shell; a rotatablewater distribution shifting piece is arranged in the water distribution cavity; a plurality of spraying outlets are formed in the second shell, and through holes are formed in the water distribution shifting piece, wherein the through holes are aligned to single or multiple spraying outlets to conduct the corresponding spraying outlets; and a positioning and detecting device for performing positioning and conducting on the through holes and the spraying outlets is arranged on the water distribution shifting piece and the second shell. According to the water distribution device, flexible conversion of single or multiple spraying water paths can be realized, the positioning is realized without calculating the conduction time of a motor through the rotation angle, accurate positioning is realized by the positioning and detecting device, so that the alignment precision of the through holes and the spraying outlets can be greatly improved, the phenomenon that the through holes are deviatedfrom the spraying outlets due to wrong rotation angle of the motor is avoided, the caused situation that water flow is reduced is prevented, and the spraying effect is improved.

Description

technical field [0001] The invention belongs to the field of dishwashers, and in particular relates to a water diversion device for a dishwasher, a dishwasher and a control method thereof. Background technique [0002] When the existing dishwasher washes the tableware, it usually cleans the tableware by injecting water into the inner container of the dishwasher, and then pumping the water into the spray pipe in the dishwasher by a circulating water pump. In order to improve the cleaning effect on greasy tableware, dishwashers usually use electric heaters or heat pump systems to heat the washing water, and then spray it onto the tableware. [0003] The current dishwasher usually has an upper spray arm and a lower spray arm; when working, the washing pump sends high pressure to the upper and lower spray arms, and the water is sprayed from the spray arm to rinse the tableware and then returns to the bottom of the dishwasher. The water cup and the washing pump deliver the retur...
