This invention discloses a washing machine drainage control method and a washing machine. The washing machine operates a drainage program, with a drain pump installed at the bottom of the outer tub. Its outlet is connected to a drain hole in the outer tub via a drain pipe, which is inclined. The washing machine's drainage program is divided into four stages. Combined with structural modifications to the washing machine, the control method includes: Stage 1: Starting the drain pump and cyclically starting and stopping; Stage 2: Starting the motor and running at low speed, cyclically rotating with long runs and short stops; Stage 3: Controlling the motor to rotate with short runs and long stops; Stage 4: Controlling the motor to run at high speed. During Stages 2, 3, and 4, the drain pump is controlled to rotate with long runs and short stops. This invention, through structural modifications and drainage timing control, allows water in the drain pipe to flow back into the pump chamber due to the inclined structure of the drain pipe during the drain pump's stop period, pushing air out of the pump's inlet and into the outer tub, thus solving the problem of air trapped in the pump.

This invention relates to the field of soybean protein product processing, and discloses a method for preparing steamed soybean protein tofu and its low-temperature segmented braising and roasting process. The method includes premixing soybean protein isolate with an ice-water mixture, sequentially adding sodium pyrophosphate, salt, and D-anhydrous glucose and chopping, adding soybean oil and sodium stearoyl lactylate and chopping, adding cold-soluble κ-carrageenan and glucono-delta-lactone, mixing and discharging, pre-gelling by heat induction, and then demolding and cutting to obtain the embryo. The embryo is then mixed with a compound flavored braising sauce and braised in two stages, followed by a first-stage dehydration and a second-stage roasting. It is then vacuum-packed and sterilized under pressure and cooled under pressure before being removed from the oven. This invention utilizes soybean protein isolate combined with an ice-water mixture and cold-soluble κ-carrageenan to form a microemulsion system. During heat induction and cooling, an interpenetrating double-network gel structure is constructed, controlling the temperature rise to prevent premature thermal denaturation and inducing uniform cross-linking to avoid pores, thereby improving the system's water and oil holding capacity and elasticity.
