Embodiment 1

[0040] When the timer described in this embodiment selects the water flow I corresponding to S2 to act, the washing contact 1 is closed, the washing contact 2 is disconnected, and the washing cam operation control contact 1 is pressed. Figure 5 The a1, a2, b1, b2 in the cycle are closed and disconnected periodically, realize the positive and negative rotation of the washing motor, and perform soaking and washing. The closing and opening time of the washing contact 1 is according to Table 1, and the synchronization starts in the first cycle The cycle cam control contact 4 is closed and disconnected in a cycle of 1min and 5min, and the inner circulation water flushing is carried out until the soaking and washing time runs T1 time; when entering the continuous washing time, the washing cam control contact 1 is pressed Figure 5 The c1, c2, d1 and d2 in the cycle are closed and disconnected to realize the positive and negative rotation of the washing motor, and the continuous wash...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that the manual switch selects the water flow II corresponding to S3, and when soaking and washing, the cycle is closed and disconnected according to a3, a4, b3, b4, and the continuous washing time is according to c3, c4, d3 , d4 is the cycle closure and disconnection. During the soaking and washing time period, the washing cam controls the power contacts to work in a cycle of 12.5s for washing and 47.5s for soaking. This process and the flushing with circulating water flow in the continuous washing process are the same as those in Embodiment 1.

Embodiment 3

[0045] The difference between this embodiment and the above-mentioned embodiment 1 and embodiment 2 is that only during the soaking and washing time, the on-off of the contact of the drainage pump is controlled to realize the internal circulating water flow flushing, while the internal circulating water flow flushing is not performed during the continuous washing time .

Abstract

The invention discloses a washing machine timer capable of controlling circulating water flow and a double-barrel washing machine. The total working time of the timer contains soaking and washing time and continuous washing time; and at least the soaking and washing time is synchronized with an internal circulating water flow washing time for controlling periodical and intermittent circulation of a water discharging pump. The timer comprises an input end, an output end and a manual converter, wherein the output end is provided with two groups of washing contacts connected with a washing motor; one washing contact of the output end is selected for connection by switching of the manual converter; the input end is provided with two groups of contacts which respectively control a power supply and the water discharging pump; the timer is also provided with a cleaning cam for switching on and off the power supply in a timing manner to control the continuous washing time and the soaking and washing time and an internal circulating cam for switching on and off the water discharging pump in a timing manner to control the internal circulating water flow washing periodically, intermittently and circularly. According to the timer disclosed by the invention, the starting and stopping of the water discharging pump can be controlled for the internal circulation of the washing water flow, so that the dissolving performance and the washing performance of washing powder are improved. The double-barrel washing machine has the characteristic of saving water and power.

Description

technical field [0001] The invention relates to a washing machine timer, in particular to a washing machine timer capable of controlling circulating water flow and a double-tub washing machine with the timer. Background technique [0002] The traditional washing timer does not have a soaking function. During the washing process, the washing machine runs continuously according to the preset program to complete the washing functions of forward, stop and reverse, so there is a problem that the detergent cannot be completely dissolved. Affects the washing degree of clothes. In response to this problem, various manufacturers have developed timers with a soaking function. [0003] The existing 45min and 35min washing timers with immersion have longer washing time, longer washing stop time and high energy consumption. This kind of timer adopts a cam sleeve added to the main shaft, so that the washing machine has a process of pausing and washing during the washing process, but thi...
