When being provided with the first connected entrance c on chiller 1, the cooling duct P of chiller 1 can be exchanged with steel ladle 2 Cold water, even can arrange water tank in washing machine 1000, chiller 1 is connected with water tank by the first connected entrance c, so, water Case also can provide coolant for chiller 1.

Due to being provided with shifting part 12 in the P of cooling duct in chiller 1, shifting part 12 can be dialled in the P of cooling duct Dynamic current.Affected by shifting part 12, the coolant in the P of cooling duct can energetically with the water source change of current in steel ladle 2, as Fig. 4 institute Show, shifting part 12 stir the effect that can improve the change of current, be conducive to quickly exhaling the heat of motor 5.

Further, as shown in Fig. 4 and Figure 15, housing 11 be provided be respectively communicated with cooling duct P coolant inlet a and Coolant outlet b, coolant inlet a is connected with water inlet pipe 3, and coolant outlet b is connected with drain valve 4.

So, during washing machine 1000 water inlet, current can be entered in the cooling duct P of chiller 1 by water inlet pipe 3 and fill Make coolant.Motor 5 work when drive on the first end cap 111 stir blade 121 and wind wheel blade 131 rotates.One side wind Motor 5 heat is directly diffused in the air and reaches air-cooled purpose by impeller blade 131, on the other hand stirs blade 121 agitation water Stream, the cooling water in the P of cooling duct is exchanged with external water source at the first connected entrance c, so that the cooling water in the P of cooling duct is kept Low temperature, reaches the purpose of water-cooled.During washing machine 1000 draining, the cooling water in the P of cooling duct can be flowed into by coolant outlet b Drain valve 4, is then discharged outside washing machine 1000 by drain valve 4.

Washing machine 1000 in this embodiment, by the use of washing machine 1000 work when water inlet as coolant, and transform Fan blade, is allowed to stir coolant while rotation, so that coolant is held with the low-temperature water source in washing machine 1000 steel ladle 2 Continuous exchange, holding low temperature, raising cooling capacity.In addition, the water inlet pipe 3 of the coolant inlet a of chiller 1 and washing machine 1000 It is connected, coolant place interlayer can be rinsed with source of clean water during washing machine 1000 water inlet, prevent residual stains in the P of cooling duct.

With " a kind of water-cooled washing motor and the washing machine applying this water-cooled washing motor " patent phase disclosed in prior art In the washing machine 1000 of this utility model embodiment, motor 5 can have air-cooled and two kinds of cooling methods of water-cooled concurrently to ratio, to motor 5 Cooling-down effect is more preferably.
