Description

The present invention relates to a technical field of garment processing equipment, and specifically provides a control method for garment processing equipment and garment processing equipment.

With the advancement of science and technology, the level of automation of human life is increasing, and machines are gradually replacing human power in daily domestic work. Clothes processing equipment provides extremely convenient people's lives as home appliances that are commonly used in daily life. Clothes processing equipment mainly includes clothes washing equipment, clothes drying equipment, and integrated washing / drying equipment, and when classified according to the washing method, the integrated washing / drying equipment is an integrated washing having a drying function. It is roughly divided into a dryer and a drum washing machine having a drying function. In the prior art, in a drum washing machine, air is heated by a heating module of a drying system, and the heated air is blown into the washing tub by a blower, so that the hot air acts on the clothes in the washing tub and acts on the clothes in the washing tub. Moisture carried by clothing is evaporated to become hot and humid steam, and the hot and humid steam is sucked into the heat exchanger, heat exchanges with the refrigerant in the heat exchanger, and is condensed into condensed water, which is condensed. Water flows out along the inner wall of the heat exchanger. In this process, heat is exchanged between the drying system and the external environment, and the higher the temperature of the external environment, the smaller the amount of heat exchanged between the drying system and the external environment, and more heat enters the drying system. As the condensation capacity of the drying system becomes weaker than the heating capacity, the judgment accuracy of automatically starting the drying program of the drying system is reduced, and as a result, the drying program does not start even though the clothes are not yet dried. Alternatively, it may end early, which greatly affects the user's experience.

In order to solve the above problems, in the conventional technique, a temperature sensor is provided in the drying duct of the drying system, and since this temperature sensor can indirectly reflect the temperature of the external environment, heating is performed based on the temperature detected by the temperature sensor.

In S221, it is determined whether or not the environmental temperature T ₁ is equal to or less than the first preset temperature threshold value.
In S222, when the environmental temperature T ₁ is equal to or less than the first preset temperature threshold, the on temperature T _on does not change.
In S223, it is determined whether or not the environmental temperature T ₁ exceeds the first preset temperature threshold value and is equal to or less than the second preset temperature threshold value.
In S224, when the environmental temperature T ₁ exceeds the first preset temperature threshold and is equal to or less than the second preset temperature threshold, the on temperature T _on is inversely proportional to the environmental temperature T ₁ .
In S225, it is determined whether or not the environmental temperature T ₁ exceeds the second preset temperature threshold value and is equal to or less than the third preset temperature threshold value.
In S226, when the environmental temperature T ₁ exceeds the second preset temperature threshold and is equal to or less than the third preset temperature threshold, the on temperature T _on is inversely proportional to the environmental temperature T ₁ .
In S227, when the ambient temperature T ₁ exceeds the third preset temperature threshold, the on temperature T _on does not change.

Specifically, in step S222, when the environmental temperature T ₁ is equal to or lower than the first preset temperature threshold value, the environmental temperature is relatively low and does not affect the detection accuracy of the temperature sensor, and the heating module needs to be turned on. It shows that it can be accurately determined whether or not there is, and the on temperature T _on is left as it is. That is, the on temperature T _on does not change with changes in the environmental temperature.

Preferably, in step S224, when the ambient temperature T ₁ exceeds the first preset temperature threshold and is equal to or less than the second preset temperature threshold, the ambient temperature is relatively high, which affects the detection accuracy of the temperature sensor. It shows that it is not possible to accurately determine whether the heating module needs to be turned on, the on temperature T _on is installed in inverse proportion to the ambient temperature T ₁ and as the ambient temperature rises. By lowering the on temperature T _on and lowering the on temperature of the heating module, it is possible to prevent the drying program from being unable to be executed even though the clothes have not been dried yet, or to end early, and integrated washing and drying. It enhances the drying effect of the machine and further improves the user's experience.

Preferably, in step S226 above, when the ambient temperature T ₁ exceeds the second preset temperature threshold and is less than or equal to the third preset temperature threshold, the ambient temperature is considerably high, affecting the detection accuracy of the temperature sensor and heating. It indicates that it is not possible to accurately determine whether the module needs to be turned on, and the on-temperature T _on is installed in inverse proportion to the ambient temperature T ₁ and turns on as the ambient temperature rises. By lowering the temperature T _on and lowering the on temperature of the heating module, it is possible to prevent the drying program from being unable to be executed even though the clothes have not been dried yet, or to end early, and it is an integrated washer-dryer. It enhances the drying effect of the product and further enhances the user's experience.

Preferably, in step S227 above, if the ambient temperature T ₁ exceeds the third preset temperature threshold, the ambient temperature is too high and the heating module needs to be turned on, which has a significant effect on the detection accuracy of the temperature sensor. It indicates that it cannot be accurately determined whether or not it is present, and the on temperature T _on is left as it is. In other words, since the on temperature T _on does not change due to changes in the environmental temperature, it is possible to prevent the drying program from being unable to be executed even though the clothes have not been dried yet, or to end early, and integrated washing and drying. Improve the drying effect of the machine and further improve the user experience.

In the above process, the conclusion on how to make the on-temperature correction so that the setting of the first preset temperature threshold allows the integrated washer / dryer to adopt the optimum correction mode in different cases. The on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved. The first preset temperature threshold value may be the lowest temperature of the environmental temperature. For example, when the first preset temperature threshold value is 10 ° C., the on-temperature correction plan is optimal, and the integrated washing and drying is performed. Increase the drying effect of the machine. Of course, the first preset temperature threshold described above is not limited to the minimum ambient temperature, but can be obtained from other temperatures, for example, the experimental temperature obtained by a person skilled in the art from an experiment under a specific operating condition, or empirically. It may be an empirical temperature, as long as the boundary point for selecting the first correction coefficient and the second correction coefficient determined in the first preset temperature threshold can satisfy the requirement to correct the on-temperature. , You may set it to any temperature.

In addition, the setting of the second preset temperature threshold further draws conclusions on how to make on-temperature corrections so that the integrated washer / dryer can adopt the optimum correction mode in different cases. Therefore, the on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved. The setting of the second preset temperature threshold value can be flexibly adjusted and set according to the actual situation. The second preset temperature threshold value is, for example, 25 ° C., and the first preset temperature threshold value is determined by the second preset temperature threshold value. The boundary point for selecting the correction coefficient of the above and the second correction coefficient may be set to any temperature as long as it can satisfy the requirement for correcting the on-temperature.

In addition, by setting a third preset temperature threshold, further conclusions can be drawn on how to make on-temperature corrections so that the integrated washer / dryer can adopt the optimum correction mode in different cases. Therefore, the on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved. By repeated testing, observation, analysis, or comparison by the inventor, it is determined that the third preset temperature threshold may be the highest temperature of the ambient temperature, for example, the third preset temperature threshold. At 35 ° C, the on-temperature correction plan is optimal and enhances the drying effect of the integrated washer-dryer. In practical applications, the actual value of the third preset temperature threshold is not limited to the maximum ambient temperature, and may be a value experimentally or empirically obtained by those skilled in the art.

It should be further explained that the off temperature of the heating module may be corrected by the above method. At least one of the first and second correction factors corresponding to the off-temperature and the first and second correction factors corresponding to the on-temperature so that the modified on-temperature is smaller than the modified off-temperature. The values may be different from at least one of the correction coefficients. Of course, the off temperature of the heating module may be set to a fixed value. The above two measures may be selected according to the actual usage needs.

Preferably, when the environmental temperature T ₁ is 10 ° C. (first preset temperature threshold) or less, the first correction factor a corresponding to the on temperature T _on is set to 0 and the second correction factor b is set to 110. That is, T _on = 110 ° C.

Preferably, if the environmental temperature T ₁ exceeds 10 ° C and is below 25 ° C (second preset temperature threshold), the first correction factor a corresponding to the on temperature T _on is -1.2 and the second correction. Let the coefficient b be 122, that is, T _on = -1.2 × T ₁ + 122.

Preferably, when the environmental temperature T ₁ exceeds 25 ° C and is 35 ° C (third preset temperature threshold) or less, the first correction factor a corresponding to the on temperature T _on is set to -2 and the second correction is made. Let the coefficient b be 142, that is, T _on = -2 × T ₁ + 142.

Preferably, when the environmental temperature T ₁ exceeds 35 ° C, the first correction coefficient a corresponding to the on temperature T _on is 0 and the second correction coefficient b is 72, that is, T _on = 72 ° C.

Of course, the value of the first correction coefficient and the value of the second correction coefficient are not limited to the values exemplified above, and can be flexibly adjusted by those skilled in the art as long as the following requirements are satisfied during actual operation. .. That is, when the ambient temperature is below the first preset temperature threshold, the on-temperature T _on does not change; when the ambient temperature is below the second preset temperature threshold, the on-temperature T _on becomes the ambient temperature T ₁ . Inversely proportional; when the ambient temperature is below the third preset temperature threshold, the on-temperature T _on is inversely proportional to the ambient temperature T _1. When the ambient temperature exceeds the third preset temperature threshold, the on-temperature T _on is It does not change.

It enhances the drying effect of the dryer and further improves the user's experience.

In the above process, the conclusion on how to make the on-temperature correction so that the setting of the first preset temperature threshold allows the integrated washer / dryer to adopt the optimum correction mode in different cases.

Therefore, the on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved. The setting of the second preset temperature threshold value can be flexibly adjusted and set according to the actual situation. The second preset temperature threshold value is, for example, 25 ° C., and the first preset temperature threshold value is determined by the second preset temperature threshold value. The boundary point for selecting the correction coefficient of the above and the second correction coefficient may be set to any temperature as long as it can satisfy the requirement for correcting the on-temperature.

In addition, by setting a third preset temperature threshold, further conclusions can be drawn on how to make on-temperature corrections so that the integrated washer / dryer can adopt the optimum correction mode in different cases. Therefore, the on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved.

In S223, it is determined whether or not the environmental temperature T ₁ is equal to or less than the first preset environmental temperature threshold, and whether or not the cooling water temperature T ₂ exceeds the first preset cooling water temperature threshold.

Specifically, in step S222, when the environmental temperature T ₁ is equal to or less than the first preset environmental temperature threshold and the cooling water temperature T ₂ is equal to or less than the first preset cooling water temperature threshold, the environmental temperature and the cooling water It shows that the temperatures are relatively low, do not affect the detection accuracy of the temperature sensor, and can accurately determine whether or not the heating module needs to be turned on, leaving the on temperature T _on as it is. That is, the on temperature T _on does not change due to changes in the environmental temperature T ₁ and the cooling water temperature T ₂ .

Preferably, in step S224, when the environmental temperature T ₁ is equal to or less than the first preset environmental temperature threshold and the cooling water temperature T ₂ exceeds the first preset cooling water temperature threshold, the environmental temperature T ₁ is relatively low. However, the cooling water temperature T ₂ is relatively high, which affects the detection accuracy of the temperature sensor and indicates that it is not possible to accurately determine whether the heating module needs to be turned on. The temperature T _on is installed so as to be inversely proportional to the environmental temperature T ₁ and the cooling water temperature T ₂ , and the on temperature T _on decreases as the environmental temperature T ₁ and the cooling water temperature T ₂ rise, and the on temperature of the heating module By lowering the temperature, it is possible to prevent the drying program from being unable to be executed even though the clothes have not been dried yet, or to end early, to enhance the drying effect of the integrated washer-dryer, and to further use by the user. Improve the experience.

Preferably, in step S226 above, when the environmental temperature T ₁ exceeds the first preset environmental temperature threshold and is equal to or lower than the second preset environmental temperature threshold, the environmental temperature is relatively high and the temperature is irrespective of the cooling water temperature. It affects the detection accuracy of the sensor and indicates that it is not possible to accurately determine whether the heating module needs to be turned on, where the on temperature T _on is the ambient temperature T ₁ and the cooling water temperature T ₂ . It is installed in inverse proportion, and as the environmental temperature T ₁ and the cooling water temperature T ₂ rise, the on temperature T _on decreases and the on temperature of the heating module is lowered, so that the clothes have not been dried yet. It is possible to prevent the drying program from becoming inoperable or ending prematurely, enhancing the drying effect of the integrated washer-dryer and further improving the user experience.

Preferably, in step S228, when the ambient temperature T ₁ exceeds the second preset ambient temperature threshold and the cooling water temperature T ₂ is less than or equal to the second preset cooling water temperature threshold, the ambient temperature is too high and the cooling water. It indicates that the temperature is relatively high, which affects the detection accuracy of the temperature _sensor and makes it impossible to accurately determine whether the heating module needs to be turned _on . It is installed so as to be inversely proportional to the cooling water temperature T ₂ , and as the environmental temperature T ₁ and the cooling water temperature T ₂ rise, the on temperature T _on decreases and the on temperature of the heating module is lowered to dry the clothes. It is possible to prevent the drying program from being unable to be executed even though it has not been completed yet, or to prevent it from ending prematurely, enhancing the drying effect of the integrated washer-dryer and further improving the user experience.

Preferably, in step S230, when the environmental temperature T ₁ exceeds the second preset environmental temperature threshold and the cooling water temperature T ₂ exceeds the second preset cooling water temperature threshold, both the environmental temperature and the cooling water temperature are preferable. It indicates that it is too high to accurately determine whether the heating module needs to be turned on, which has a very large effect on the detection accuracy of the temperature sensor, and the on temperature T _on is left as it is. In other words, the on-temperature T _on does not change due to changes in the ambient temperature T ₁ and the cooling water temperature T ₂ , so that the drying program cannot be executed even though the clothes have not been dried yet, or it ends early. Can be avoided, the drying effect of the integrated washer / dryer is enhanced, and the user's experience of use is further improved.

In the above process, by setting the first preset ambient temperature threshold and the first preset cooling water temperature threshold, the integrated washer / dryer can adopt the optimum correction mode when different, so that the on-temperature can be adopted. Further conclusions about how to make the correction can be made to accurately determine the on-temperature of the heating module, and the drying effect of the integrated washer-dryer can be improved. The first preset environmental temperature threshold may be the lowest temperature of the ambient temperature, and the first preset cooling water temperature threshold may be the lowest temperature of the cooling water temperature. For example, the first preset cooling water temperature threshold may be the lowest temperature. When the preset ambient temperature threshold is 10 ° C and the first preset cooling water temperature threshold is 10 ° C, the on-temperature modification is optimal and enhances the drying effect of the integrated washer-dryer. Of course, the first preset environmental temperature threshold and the first preset cooling water temperature threshold are not limited to the temperatures exemplified above, but are other temperatures, for example, experimental temperatures obtained by those skilled in the art from experiments under specific operating conditions. , Or an empirical temperature obtained empirically, the first correction coefficient, the second correction coefficient, and the third correction factor determined by the first preset environmental temperature threshold and the first preset cooling water temperature threshold. The boundary point for selecting the correction factor and the fourth correction factor may be set to any temperature as long as the on-temperature correction requirement can be satisfied.

In addition, by setting the second preset ambient temperature threshold and the second preset cooling water temperature threshold, which of the on-temperature modifications can be made so that the integrated washer-dryer can adopt the optimum modification mode when different. Further conclusions can be drawn as to how to do so, the on-temperature of the heating module can be accurately determined, and the drying effect of the integrated washer-dryer can be improved. The setting of the second preset environmental temperature threshold value and the second preset cooling water temperature threshold value can be flexibly adjusted and set according to the actual situation. For example, the second preset environmental temperature threshold value is 35 ° C. The 2 preset cooling water temperature threshold is 35 ° C, and the boundary point for selecting the 1st correction coefficient and the 2nd correction coefficient determined for the 2nd preset ambient temperature threshold and the 2nd preset cooling water temperature threshold. However, it may be set to any temperature as long as it can meet the requirement to correct the on-temperature.

It should be further explained that the off temperature of the heating module may be corrected by the above method. At least one of the first and second correction factors corresponding to the off-temperature and the first and second correction factors corresponding to the on-temperature so that the modified on-temperature is smaller than the modified off-temperature. The values may be different from at least one of the correction coefficients. Of course, the off temperature of the heating module may be set to a fixed value. The above two measures may be selected according to the actual usage needs.
