The high-temperature cooking method of the present invention is described below in conjunction with above-mentioned two-cylinder washing machine:

Referring to FIG. 2 again, FIG. 2 is a flow chart of the steps of the high-temperature cooking method of the dual-tub washing machine of the present invention. As shown in Figure 2, the high-temperature cooking method of the dual-tub washing machine of the present invention includes:

Step S1: make the first heating unit of the heating device heat the first washing tub 1, and make the three-way valve 3 block the first valve port;

Step S2: obtaining the washing water temperature of the first washing tub 1;

Step S3: when the temperature of the washing water in the first washing tub 1 reaches the first cooking temperature, stop the first heating unit from heating the first washing tub 1, and make the second heating unit heat the second washing tub 2;

Step S4: obtaining the cooling temperature of the washing water of the first washing tub 1 and the temperature of the washing water of the second washing tub 2;

Step S5: if the cooling temperature of the washing water of the first washing tub 1 drops to the preset temperature, the three-way valve 3 is switched to the valve position and the valve port communicating with the second washing tub 2 is blocked;

Step S6 : when the temperature of the washing water in the second washing tub 2 reaches the second cooking temperature, stop the second heating unit from heating the second washing tub 2 .

In the above steps, "the temperature of the washing water in the first washing tub 1" is the temperature at which the washing water in the first washing tub 1 is heated. "The temperature of the washing water in the second washing tub 2" is the temperature at which the washing water in the second washing tub 2 is heated. The "first cooking temperature" is the highest temperature that the first washing tub 1 can raise after the internal washing water is heated in the high-temperature cooking process. The "second cooking temperature" is the highest temperature that the second washing tub 2 can raise after the internal washing water is heated in the high-temperature cooking process. The set values of the first cooking temperature and the second cooking temperature may be the same or different, and those skilled in the art can set the specific temperature values of the first cooking temperature and the second cooking temperature according to the needs of cooking and disinfection. Exemplarily, the first cooking temperature is a temperature value greater than 90°C, the second cooking temperature is the same as the first cooking temperature, for example, the first cooking temperature and the second cooking temperature are both 95°C, the first heating unit When the washing water in the washing tub 1 is heated to 95°C, it stops working, and at the same time, the second heating unit starts to heat the washing water in the second washing tub 2 until the washing water in the second washing tub 2 is heated to 95° C. High temperature cooking The heating work in the program is completed. The "cooling temperature of the washing water of the first washing tub 1" is the temperature of the washing water in the cooling process after the first washing tub 1 is not heated. The "preset temperature" is the set expected cooling value of the washing water cooling temperature of the first washing tub 1. When the washing water cooling temperature of the first washing tub 1 is lowered to the expected cooling value, the The amount of steam generated by the washing water is small, and after a small amount of steam escapes from the first washing tub 1, it will condense, evaporate and dissipate on the way to escape from the interior of the double-tub washing machine, even if a very small amount of steam can escape from the double tub. When the washing machine escapes, the escaping steam will quickly dissipate into the air, and the impact on the decoration environment and visual environment will be negligible. Preferably, the above-mentioned preset temperature is any temperature value between 50°C and 60°C (including 50°C and 60°C), such as 60°C. The temperature parameters that need to be acquired, such as the temperature of the first washing water, the temperature of the second washing water, and the cooling temperature of the washing water of the first washing tub 1, can be obtained by a temperature acquiring device such as a temperature sensor provided in the corresponding washing tub.

Through the above steps, the temperature of the washing water in the first washing tub 1 can be lowered to a preset temperature as an opportunity for the three-way valve 3 to switch the blocking position of the valve core, so that the temperature of the washing water in the first washing tub 1 is higher and the generation of When there is a large amount of steam, the steam escaping from the washing tub is blocked to prevent a large amount of steam from escaping from the first washing tub 1 to the outside of the double-tub washing machine, and the temperature of the washing water in the first washing tub 1 is reduced and the amount of steam generated When there is less steam and the steam can hardly escape to the outside of the double-tub washing machine, perform the valve core position switching operation of the three-way valve 3, so that the valve core blocks the second valve port, so that the temperature of the washing water in the second washing tub 2 rises to Block the passage of the washing tub through which the steam can escape before the higher temperature and the amount of steam generated sharply increase, and block the first washing tub 1 and the second washing tub 2 from escaping in turn by switching the three-way valve 3 at the set time. A large amount of steam, thereby minimizing the total amount of steam that escapes from the first washing tub 1 and the second washing tub 2 during the execution of the entire high-temperature cooking process.

In a possible implementation manner, the heating power of the washing water in the second washing tub 2 can be controlled by adjusting the heating power of the washing water in the second washing tub 2 . The decreasing speed of the water cooling temperature appropriately increases or decreases the output power of the second heating unit, thereby increasing or decreasing the increasing speed of the washing water temperature of the second washing tub 2, so that the washing water cooling temperature of the first washing tub 1 drops to At the preset temperature, the washing water in the second washing tub 2 is controlled to be heated to a temperature that does not exceed the preset temperature, preferably the second washing tub is made when the cooling temperature of the washing water in the first washing tub 1 drops to the preset temperature. The temperature of washing water in When the washing water of the second washing tub 2 is about to escape more steam, control the three-way valve 3 to switch the valve core from the first valve port to the second valve port in time, so that when the two washing tubs generate a large amount of steam, each washing tub can The corresponding valve ports can all be in a closed state, thereby effectively reducing the overall steam escape. Of course, in addition to controlling the heating power of the second heating unit, those skilled in the art can also estimate or control the heating speed of the washing water in the second washing tub 2 in combination with the amount of washing water in the second washing tub 2 .

In another possible embodiment, the high-temperature cooking method of the double-tub washing machine of the present invention further comprises:

If the washing water cooling temperature of the first washing tub 1 is greater than the preset temperature and the washing water temperature of the second washing tub 2 is within the set temperature range, the second heating unit is temporarily stopped to heat the second washing tub 2;

Obtain the cooling temperature of the washing water of the first washing tub 1 again;

When the washing water cooling temperature of the first washing tub 1 drops to a preset temperature, the second heating unit continues to heat the second washing tub 2, wherein the maximum temperature value of the set temperature range is less than or equal to the preset temperature.

In the above steps, the temperature values within the set temperature range are all close to and less than the preset temperature. Before the cooling temperature of the washing water in the first washing tub 1 is lowered to the preset temperature, once the temperature of the washing water in the second washing tub 2 rises Within the set temperature range, controlling the second heating unit to suspend the operation can temporarily stop the washing water temperature of the second washing tub 2 from continuing to rise, and prevent the three-way valve 3 from switching the valve core to the blocking position of the second valve port. The washing tub 2 has already started to emit a large amount of steam to the outside. When the cooling temperature of the washing water in the first washing tub 1 drops to the preset temperature, the three-way valve 3 controls the valve core to block the second valve port, and at this time, the second heating unit continues to be the washing water in the second washing tub 2 After that, even if the temperature of the washing water in the second washing tub 2 quickly rises to outside the set temperature range or even exceeds the preset temperature, a large amount of steam that gradually increases in the second washing tub 2 will be blocked by the valve core rather than escaping to the outside. Among them, the above-mentioned set temperature range is preferably 40°C to 50°C.

In yet another possible embodiment, the high-temperature cooking method of the dual-tub washing machine of the present invention further comprises:

In the case where the washing water cooling temperature of the first washing tub 1 is greater than the preset temperature and the washing water temperature of the second washing tub 2 is raised to the preset temperature, if the washing water cooling temperature of the first washing tub 1 drops to less than or When the temperature of the washing water in the second washing tub 2 is equal, the three-way valve 3 switches the valve position and blocks the valve port of the second washing tub 2 .

In the above steps, if the temperature of the washing water in the second washing tub 2 has risen to the preset temperature before the cooling temperature of the washing water in the first washing tub 1 drops to the preset temperature, the first washing tub 1 and the second washing tub The washing water in 2 can escape a large amount of steam. In this case, if the cooling temperature of the washing water in the first washing tub 1 drops to less than or equal to the washing water temperature in the second washing tub 2, it indicates that the second washing tub 2 The temperature of the washing water is higher and the amount of steam generated is more. At this time, there is no need to wait for the cooling temperature of the washing water of the first washing tub 1 to drop to the preset temperature, and the three-way valve 3 is directly controlled to seal the valve core from the first valve port. The blocking position is switched to the blocking position of the second valve port, thereby blocking the second washing tub 2 with more steam that can escape. If the cooling temperature of the washing water in the first washing tub 1 is greater than that in the second washing tub 2 If the water temperature is higher, the state that the three-way valve 3 blocks the first valve port is maintained, thereby blocking the first washing tub 1 with more steam that can escape.

Based on any of the above-mentioned embodiments, the step of "making the three-way valve 3 block the first valve port" includes:

When the first heating unit heats the washing water of the first washing tub 1 and the three-way valve 3 blocks the second valve port (that is, when the washing water of the first washing tub 1 is heated, the valve core of the three-way valve 3 is not in the The blocking position of the first valve port), if the temperature of the washing water of the first washing tub 1 reaches the preset temperature, the three-way valve 3 is made to switch the blocking position of the valve core from the second valve port to the first valve port;

When the first heating unit heats the washing water of the first washing tub 1 and the three-way valve 3 blocks the first valve port (that is, when the washing water of the first washing tub 1 is heated, the valve core of the three-way valve 3 is already in The blocking position of the first valve port), the three-way valve 3 is kept in the state of blocking the first valve port.

Of course, in the above-mentioned first situation, when the temperature of the washing water of the first washing tub 1 reaches the preset temperature, it is only the latest time for the three-way valve 3 to switch the blocking position of the valve core to the first valve port. Among them, before the temperature of the washing water in the first washing tub 1 does not exceed the preset temperature, the three-way valve 3 can also switch the valve core to the position of blocking the first valve port at any time.
