Example Embodiment

[0039] Example one

[0040] When the timer 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, and b2 in the cycle are closed and disconnected, which realizes the forward and reverse rotation of the washing motor, and performs immersion washing. The closing and disconnecting time of the washing contact 1 is in accordance with Table 1, and the first cycle starts to be synchronized Circulation cam control contact 4 is closed and disconnected in a cycle of 1 minute and 5 minutes as the cycle, and the internal circulating water flow is rinsed until the end of the soaking washing time running T1; when the continuous washing time is entered, the washing cam control contact 1 is pressed Figure 5 The c1, c2, d1, d2 in the cycle are closed and disconnected to realize the positive and negative rotation of the washing...

Example Embodiment

[0042] Example two

[0043] The difference between this embodiment and the first embodiment is that the manual switch switches and selects the water flow II corresponding to S3. During soaking and washing, a3, a4, b3, and b4 are cyclically closed and disconnected, and the continuous washing time is in accordance with c3, c4, d3. , D4 is the cycle of closing and opening. During the immersion washing time period, the washing cam controls the power contact to work in cycles with the power-on washing 12.5s disconnecting the soaking to 47.5s. This process and the continuous washing process are the same as the first embodiment.

Example Embodiment

[0044] Example three

[0045] The difference between this embodiment and the above-mentioned first and second embodiments is that it only controls the on and off of the drain pump contact during the soaking washing time to realize the internal circulating water flow cyclic washing, but does not operate the internal circulating water washing 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...
