Description

Technical Field

[0001] The present invention relates to a storage method for a dishwasher, a dishwasher, and a storage medium. Background Art

[0002] Existing dishwashers for tableware cleaning generally have a storage function, and some dishwashers are also compatible with a disinfection function to meet the long-term storage of tableware within the period. For dishwashers with a storage function, after the cleaning is completed, the tableware in the cavity will be dried and then enter the storage sequence. During the storage process, due to changes in the external environment, the internal environment of the dishwasher cavity will change. For example, when the external environmental humidity is high, the humidity in the dishwasher cavity will also increase; or when the temperature difference between day and night is large due to seasonal changes, the dishwasher cavity will also experience moisture return. A humid environment is prone to bacterial growth and contamination of tableware. The current storage function of dishwashers usually adopts a fixed time sequence, that is, the internal of the dishwasher is dried and dehumidified according to the set time and duration. However, this fixed time sequence will cause excessive energy consumption when the humidity in the storage environment of the dishwasher is low, and cannot effectively dry and dehumidify in time when there is moisture return in the dishwasher, resulting in problems such as bacterial growth and insufficient storage capacity. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a storage method for a dishwasher that can be stored in a timely manner based on changes in the storage environment inside the dishwasher and can fully ensure the storage effect generated by energy consumption in view of the above-mentioned prior art.

[0006] The technical solution adopted by the present invention to solve the above first technical problem is: A storage method for a dishwasher. After the dishwasher enters the storage stage, the temperature T-in in the storage space of the dishwasher, the absolute humidity RH-out of the external environment of the dishwasher, and the temperature T-out of the external environment of the dishwasher are obtained in real time. According to different situations of the temperature T-in in the storage space of the dishwasher, the absolute humidity RH-out of the external environment of the dishwasher, and the temperature T-out of the external environment of the dishwasher, the storage work is controlled by adopting a storage mode with different storage parameters.

[0007] To reduce costs, obtain more information, and improve the intelligence level of the dishwasher, the absolute humidity RH-out outside the dishwasher and the ambient temperature T-out outside the dishwasher are obtained in real time through a communication network.

[0008] To ensure the storage environment of tableware in the dishwasher for a long time and avoid bacterial growth, the storage work is cycled based on the time period t.

At the same time, when the ventilation time reaches the first threshold time Time-1, stop the ventilation work;

[0013] The third storage mode: Control the heating work and ventilation work to be turned on in the storage space of the dishwasher. When the heating time reaches the third threshold time Time-3, stop the heating work. At the same time, when the ventilation time reaches the first threshold time Time-1, stop the ventilation work;

[0025] As an improvement, obtain the calendar time and the usage area information of the washing machine through the communication network.

[0026] When the washing machine is in a winter environment, control to compare RH-out with the environmental absolute humidity threshold RH0. If RH-out ≤ RH0, perform the storage work based on the second storage mode; otherwise, perform the storage work based on the first storage mode.

[0027] When the washing machine is in a time period and area with the characteristics of the plum rain season, control the washing machine to perform the storage work based on the first storage mode.

[0028] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a washing machine, including a body having a storage space, a drying module, an environmental parameter detection module, a controller, and a memory provided in the body. The drying module, the environmental parameter detection module, and the memory are respectively electrically connected to the controller. Computer instructions are stored in the memory, and the controller executes the foregoing storage method of the washing machine by executing the computer instructions.

[0029] Preferably, the environmental parameter detection module includes a temperature and humidity sensor for detecting the temperature and humidity data inside the body, and a wireless communication module for obtaining the external environmental parameters of the body.

At the same time, it can also give full play to the storage effect generated by the storage energy consumption, avoid energy consumption waste, and achieve the purpose of efficient cleaning and storage and energy saving.

[0033] The dishwashing machine applying the storage method of the dishwashing machine has more intelligent storage work, and on the basis of effectively saving energy, it can ensure good storage effect. Description of the Drawings

[0034] Figure 1 It is a flowchart of the storage method of the dishwashing machine in the embodiment of the present invention. Detailed Embodiments

[0035] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0036] As Figure 1 shown, the storage method of the dishwashing machine in this embodiment can be applied to a dishwashing machine with a storage function.

[0037] For a dishwashing machine with a storage function, in order to realize the storage function, a drying module is usually set. The dishwashing machine in this embodiment includes a body with a storage space, a drying module, an environmental parameter detection module, a controller, and a memory arranged in the body. The drying module, the environmental parameter detection module, and the memory are respectively electrically connected to the controller. The memory stores computer instructions, and the controller executes the following storage method of the dishwashing machine by executing the computer instructions.

[0038] The storage space in the body is usually the cleaning space. After the dishwashing machine completes the cleaning and drying work, there is no need to take out the tableware again, and the subsequent storage work can be directly carried out. Of course, the storage space can also be an independent space independent of the cleaning space in the body, and the devices required for the following storage work can be set in the storage space. Based on this, the storage method of the dishwashing machine in this embodiment can also be applied to any household appliance with a storage space and capable of carrying out storage work.

[0039] The environmental parameter detection module includes a temperature and humidity sensor for detecting the temperature and humidity data in the storage space of the machine body, and a wireless communication module for obtaining the external environmental parameters of the machine body. The temperature and humidity sensor and the wireless communication module are both electrically connected to the controller. The wireless communication module can obtain the application geographical location of the washing machine through the communication network, including various data such as external environmental information data including external temperature and humidity data. At the same time, it can also cooperate with other electrical appliances for intelligent linkage, greatly improving the intelligence level of the washing machine. On the premise of realizing the intelligence of the washing machine, it can save a temperature and humidity sensor for detecting the temperature and humidity of the external environment of the washing machine, reducing the device cost of the washing machine.

[0040] The drying module includes a fan and a heating module. The fan and the heating module are both electrically connected to the controller. Corresponding channels are provided in the washing machine to cooperate with the fan to realize the intake of air into the storage space and at the same time realize the exhaust of air outside the storage space, so that the air flow passes through the storage space, thereby improving the drying speed of the storage space. The heating module can be various heating devices in the prior art, such as a PCT module can be used.

[0041] The storage method of the washing machine in this embodiment is that after the washing machine enters the storage stage, it obtains the temperature T-in in the storage space of the washing machine, the absolute humidity RH-out of the external environment of the washing machine, and the temperature T-out of the external environment of the washing machine in real time. According to the different situations of the temperature T-in in the storage space of the washing machine, the absolute humidity RH-out of the external environment of the washing machine, and the temperature T-out of the external environment of the washing machine, it controls the use of storage modes with different storage parameters to carry out storage work. In this embodiment, the data such as the absolute humidity RH-out of the external environment of the washing machine and the temperature T-out of the external environment of the washing machine can be obtained in real time through the communication network. Among them, the absolute humidity RH-out of the external environment of the washing machine is the data converted according to the environmental humidity, which is more conducive to the calculation of the storage work in the storage space. Because the condensation phenomenon is an important factor leading to the increase of humidity in the storage space and the subsequent growth of bacteria, and the condensation phenomenon is because at a certain temperature, the water content per unit volume of air, that is, the absolute humidity, is greater than its saturated absolute humidity. Thus, using the absolute humidity RH-out of the external environment of the washing machine is more conducive to the judgment of whether to carry out storage work.

[0042] As mentioned above, in this embodiment, by obtaining the absolute humidity RH-out of the external environment of the washing machine and the temperature T-out of the external environment of the washing machine in real time through the communication network, not only can the device cost of the washing machine be reduced, but also more information can be obtained, improving the intelligence level of the washing machine.

[0043] Since the external environment usually changes unpredictably, it is impossible to ensure that the environment of the storage space meets the storage environment requirements of tableware for a long time. In order to effectively ensure the storage environment of tableware in the dishwasher and avoid bacterial growth, within the set storage time Time-D, the storage work is cycled based on the time period t. That is, after completing one storage work, after an interval of time t, the real-time temperature T-in in the storage space of the dishwasher, the absolute humidity RH-out of the external environment of the dishwasher, and the temperature T-out of the external environment of the dishwasher are obtained again. Then, based on different situations of the temperature T-in in the storage space of the dishwasher, the absolute humidity RH-out of the external environment of the dishwasher, and the temperature T-out of the external environment of the dishwasher, the storage work is controlled using storage modes with different storage parameters. After the dishwasher enters the storage stage, the storage time Time-A is updated in a timely manner. When the storage time Time-A reaches Time-D, the storage work is completely finished.

[0044] In addition, due to some special environmental conditions, there will be some situations with relatively strict storage requirements. For example, during the plum rain season in southern China, the humidity is very high, and the probability of bacteria growing in the storage space is much greater than in other environmental situations. If the storage work is determined according to a fixed time period, it is easy for bacteria to grow in the storage space when making a judgment. Therefore, in special environmental situations similar to the plum rain season, the time period for carrying out the storage work needs to be shortened. Based on this, in this embodiment, the calendar time and the usage area information of the dishwasher are obtained through the communication network, and the time period t is controlled and adjusted. The specific calendar time, usage area information, and time period can be obtained by simulating various environmental conditions during product research and development.

[0045] The storage modes in this embodiment include the first storage mode, the second storage mode, and the third storage mode, and these storage modes are respectively applicable to different situations.

[0046] First storage mode: Control to turn on the heating work and ventilation work in the storage space of the dishwasher. When the heating time reaches the first threshold time Time-1, stop the heating work, and at the same time, when the ventilation time reaches the first threshold time Time-1, stop the ventilation work;

[0047] Second storage mode: Control to turn on the heating work and ventilation work in the storage space of the dishwasher until the heating time reaches the second threshold time Time-2, stop the heating work, and at the same time, when the ventilation time reaches the first threshold time Time-1, stop the ventilation work;

[0048] The third storage mode: Control the start of heating and ventilation operations in the storage space of the dishwasher. When the heating time reaches the third threshold time Time-3, stop the heating operation. At the same time, when the ventilation time reaches the first threshold time Time-1, stop the ventilation operation;

[0049] Among them, Time-1 > Time-2 > Time-3, and Time-1, Time-2, and Time-3 can be obtained through experiments on the specific model of the dishwasher. Also, from the magnitude relationship of Time-1, Time-2, and Time-3, it can be seen that the drying intensity of the first storage mode is the highest, the drying intensity of the second storage mode is the second highest, and the drying intensity of the third drying mode is the lowest. According to the temperature and humidity differences inside and outside the storage space of the dishwasher, different storage modes are adopted for storage work, so that after the drying work is completed, the storage requirements can be met and energy consumption can be saved as much as possible.

[0050] Specifically, the storage method of the dishwasher in this embodiment includes the following steps S1 to S9.

[0051] S1. The dishwasher enters the storage stage.

[0052] S2. Real-time obtain the temperature T-in inside the storage space of the dishwasher, the ambient absolute humidity RH-out outside the dishwasher, and the ambient temperature T-out outside the dishwasher.

[0053] S3. Calculate the temperature difference ΔT = |T-in - T-out| between inside and outside the storage space of the dishwasher.

[0054] S4. Compare ΔT with the temperature difference threshold Tx; if ΔT < Tx, it means that the temperature difference between inside and outside the storage space is small. At this time, the humidity situation outside the environment directly affects the humidity situation inside the storage space. The higher the humidity outside the environment, the higher the humidity inside the storage space is likely to be, and the easier it is to breed bacteria. In this case, go to step S5. Otherwise, it means that the temperature difference between inside and outside the storage space is relatively large, and condensation is likely to occur due to the temperature difference, and then go to step S6.

[0055] S5. Compare RH-out with the ambient absolute humidity threshold RH0. If RH-out < RH0, it means that the ambient humidity is relatively low, which is beneficial to the storage of tableware in the storage space, and the current storage work ends. Otherwise, it is not conducive to the storage of tableware in the storage space. However, because there is no additional condensation caused by the temperature difference between inside and outside, the humidity inside the storage space is only affected by the ambient humidity, and a good storage effect can be achieved without high-intensity drying. In this case, perform storage work based on the second storage mode.

[0056] S6. Compare T-out with the high temperature threshold T-high; if T-out ≥ T-high, it indicates that the external environmental temperature is relatively high. In the case of a relatively high environmental temperature, based on common sense, both the temperature level of the temperature environment and the stability of the environmental humidity are relatively poor. It is necessary to determine the specific working mode of the storage work according to the specific conditions of the external environmental temperature and environmental humidity. Based on this, step S7 is carried out. Otherwise, it indicates that the temperature environment is relatively low, and in this case, condensation is likely to occur, and the storage work is carried out based on the first storage mode.

[0057] S7. Compare T-in with the high temperature threshold T-high; if T-in ≥ T-high, it indicates that the internal and external environmental temperatures of the storage space are relatively high and condensation is not likely to occur, then step S8 is carried out. Otherwise, the temperature difference between the inside and outside of the storage space may be relatively large and condensation may occur, and step S9 is carried out.

[0058] S8. Compare RH-out with the environmental absolute humidity threshold RH0. If RH-out ≤ RH0, it indicates that the environmental humidity is also relatively low, which is conducive to the storage of tableware in the storage space. Only a relatively low drying parameter needs to be used for drying to achieve a good storage effect. In this way, the storage work is carried out based on the third storage mode. Otherwise, the storage work is carried out based on the second storage mode.

[0059] S9. Compare RH-out with the environmental absolute humidity threshold RH0. If RH-out ≤ RH0, then the storage work is carried out based on the second storage mode. Otherwise, the storage work is carried out based on the first storage mode.

[0060] In addition, in some special seasonal external environmental situations, such as the winter environment and the plum rain season in southern China, the external environment remains in a state with obvious and relatively stable temperature and humidity characteristics for a long time. Detecting data frequently through the aforementioned steps S1 - S9 to determine the storage mode wastes the computing power of the controller. For such situations, the selection of the storage mode can be simplified, and a relatively fixed storage mode can be adopted for the storage work. Specifically, obtain the calendar time and the usage area information of the dishwasher through the communication network; determine the special environmental situation according to the calendar time and the usage area information of the dishwasher. When the dishwasher is in the winter environment, usually the temperature difference between the inside and outside of the storage space of the dishwasher is not large, and the selection of the storage mode depends more on the humidity situation of the external environment of the storage space. In this way, control to compare RH-out with the environmental absolute humidity threshold RH0. If RH-out ≤ RH0, then the storage work is carried out based on the second storage mode. Otherwise, the storage work is carried out based on the first storage mode. When the dishwasher is in the time period and area with the characteristics of the plum rain season, the environmental absolute humidity will significantly exceed the saturated absolute humidity of the air for a long time. In this way, control the dishwasher to carry out the storage work based on the first storage mode.

[0061] The specific determination of the data range for the winter environment, the time period and region characteristics of the plum rain season is specifically determined according to the preliminary experimental data solved in product research and development.

[0062] The storage method of the cleaning machine in the present invention can adjust the storage mode of the cleaning machine based on the temperature and humidity changes inside and outside the storage space of the cleaning machine, which can not only achieve timely storage and avoid the occurrence of bacterial growth. At the same time, it can also give full play to the storage effect generated by the storage energy consumption, avoid energy consumption waste, and achieve the purpose of efficient cleaning and storage and energy saving.

[0063] The cleaning machine applying the storage method of the cleaning machine has a more intelligent storage work, and on the basis of effective energy saving, it ensures a good storage effect.
