Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dual-drive water circuit system for a dishwasher. Background Technology

[0002] A dishwasher's water circuit typically includes a water pump, a water distribution valve, an upper spray arm assembly, and a lower spray arm assembly. The water pump is connected to the water distribution valve, which in turn connects to the upper and lower spray arm assemblies. Water is drawn by a single water pump and then distributed to the upper and lower spray arm assemblies through the water distribution valve to drive them to rotate and discharge water. However, the water distribution through the water distribution valve results in water pressure loss, thus requiring a more powerful water pump to ensure the proper functioning of the upper and lower spray arm assemblies, which increases costs.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a dual-drive water circuit system for a dishwasher that is simple in structure, has low water pressure loss, low cost, good cleaning effect, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A dual-drive water circuit system for a dishwasher designed for this purpose includes a water inlet circuit disposed within a base, a washing tank disposed on the base, and an upper spray arm assembly and a lower spray arm assembly disposed on the washing tank. The system is characterized by further including a first drive water circuit and a second drive water circuit disposed within the base. The water inlet circuit is connected to both the first and second drive water circuits. The first drive water circuit is connected to the upper spray arm assembly to drive the upper spray arm assembly to operate, and the second drive water circuit is connected to the lower spray arm assembly to drive the lower spray arm assembly to operate.

[0006] The first drive water circuit includes a first water outlet channel and a first water pump. The water inlet channel is connected to the upper spray arm assembly through the first water outlet channel, and the first water pump is installed on the first water outlet channel.

[0007] The second drive water circuit includes a second water outlet channel and a second water pump. The water inlet channel is connected to the lower spray arm assembly through the second water outlet channel, and the second water pump is installed on the second water outlet channel.

[0008] The water inlet circuit includes a water softener, an inlet channel, and a water collection cup. The water softener is connected to the water source, and the water softener is connected to the water collection cup through the inlet channel. The water collection cup is connected to the first outlet channel and the second outlet channel respectively.

[0009] A first mounting head is provided between the water inlet channel and the water collection cup. The water inlet channel is connected to the water collection cup through the first mounting head, and a water pump is provided on the first mounting head.

[0010] The first water outlet channel includes a first channel, a second mounting head, and a second channel. The water collection cup, the first channel, the second mounting head, the second channel, and the upper spray arm assembly are connected in sequence. The first water pump is installed on the second mounting head.

[0011] The second water outlet channel includes a third channel, a third mounting head, and a fourth channel. The water collection cup, the third channel, the third mounting head, the fourth channel, and the lower spray arm assembly are connected in sequence. The second water pump is installed on the third mounting head.

[0012] An auxiliary nozzle is installed on the washing tank, and the second channel is connected to the auxiliary nozzle.

[0013] The first water outlet channel also includes a fifth channel. The washing tank is provided with mounting holes for installing the upper spray arm assembly. The second channel, the fifth channel, the mounting holes and the upper spray arm assembly are connected in sequence.

[0014] The washing tank is equipped with a connector for installing the lower spray arm assembly, and the fourth channel is connected to the lower spray arm assembly through the connector.

[0015] The dual-drive water circuit system of this dishwasher is achieved by setting a first drive water circuit and a second drive water circuit inside the base. The first drive water circuit provides water flow to the upper spray arm assembly, and the second drive water circuit provides water flow to the lower spray arm assembly. That is, water is pumped to the upper spray arm assembly and the lower spray arm assembly by two water pumps respectively, which can greatly reduce water pressure loss. Therefore, two water pumps with very low power can be used. The total power of the two water pumps is less than that of the traditional single water pump. Moreover, the traditional water distribution valve can be eliminated, which reduces costs while ensuring the normal operation of the upper spray arm assembly and the lower spray arm assembly.
