Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of cleaning equipment, and in particular to an intelligent cleaning storage control method for a dishwasher. Background Art

[0002] Existing washing machines such as dishwashers generally have storage functions. Some high-end models can even replace some functions of disinfection cabinets and store tableware for a long time. Generally speaking, dishwashers control the humidity in the cavity through hot air drying components, such as drying tableware with hot air after washing, such as circulating hot air regularly (timing + time timing control) in storage mode to reduce the risk of moisture re-entry and avoid odor and bacterial growth. The problems with the above hot air drying method are: first, basically, the hot air is turned on regularly for drying (relatively blind in timing), which cannot adapt to the differences and changes brought about by different regions, climates, and floors; second, the scheduled hot air drying will be limited by operations such as turning on and off the machine / plugging and unplugging the power supply, forgetting to set the storage mode, and not knowing how long the storage cycle is more appropriate (after expiration, the cleaning storage function needs to be restarted again), which greatly affects the customer experience; third, regular hot air drying brings about an increase in energy consumption, but the drying efficiency is low, and it cannot accurately target the situation when the humidity increases. The humid and damp weather with high humidity may not meet the drying needs and conditions. That is, after the existing dishwasher finishes cleaning and enters the storage sequence, the start and pause of the hot air component is mainly controlled by time. When the ambient humidity is very high, if the drying is still carried out according to the inherent frequency, moisture may return between two dryings, affecting the user experience; when the ambient humidity is very low, the cavity is relatively less prone to moisture return. If the drying is still carried out according to the original time, the drying frequency is too high, which has an adverse effect on the life of the hot air component and is very energy-saving and environmentally unfriendly. In summary, there is a need to further improve the cleaning storage control method of the existing dishwasher. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an intelligent cleaning storage control method for a dishwasher that can perform cleaning storage in stages and achieve efficient cleaning and good energy-saving effects in response to the above-mentioned existing technical status.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: the intelligent cleaning storage control method of the dishwasher, the dishwasher includes a cavity, a hot air component is installed on the side wall of the cavity, the hot air component has an air inlet duct connected to the inside of the cavity, the hot air component also includes a heating element and a fan arranged in the air inlet duct, and also includes a humidity sensor capable of detecting the humidity of the environment outside the cavity, characterized in that the intelligent cleaning storage control method is as follows:

[0005] After the dishwasher finishes washing, the first stage is started. In the first stage, the hot air component first works for a preset time, and then stops working for a preset time;

[0006] In the second stage, after the first stage, the humidity sensor performs humidity detection and compares the detected humidity value with the preset humidity value, and controls the preset working time and pause time of the hot air component according to different comparison results;

[0007] In the third stage, after the second stage, the humidity sensor performs humidity detection and compares the detected humidity value with the humidity preset value, and controls the preset working time and pause time of the hot air component accordingly according to different comparison results. Moreover, the humidity preset value of the second stage is smaller than the humidity preset value of the third stage, and the preset pause time of the hot air component in the second stage is smaller than the preset pause time of the third stage.

[0008] Preferably, the first stage comprises the following steps:

[0009] S1, after the dishwasher finishes washing, it enters the first stage of storage;

[0010] S2, the hot air component starts and works for a preset time;

[0011] S3, the hot air component suspends operation for a preset time, and returns to step S2;

[0012] S4, open the drain valve;

[0013] S5. The first stage of custody ends and the second stage begins.

[0014] More preferably, the second stage comprises the following steps:

[0015] S6, determining whether the humidity of the external environment of the cavity detected by the humidity sensor is higher than a preset value H1;

[0016] If yes, execute step S7;

[0020] S9, determining the relationship between the hot air component pause time T and the preset pause time T1 and T2;

[0021] If T1≤T<T2, proceed to step S10;

[0022] If T≥T2, execute step S7;

[0023] S10, determining whether the total duration of the program is greater than a preset duration;

[0024] If so, the second stage of custody ends and the third stage begins;

[0025] If not, execute step S6.

[0026] Further preferably, the third stage comprises the following steps:

[0027] S11, determining whether the humidity of the external environment of the cavity detected by the humidity sensor is higher than a preset value H2, and H1<H2;

[0028] If yes, execute step S12;

[0029] If not, continue to execute step S11;

[0031] S13, hot air component pause time T;

[0032] S14, determining the relationship between the hot air component pause time T and the preset pause time T3 and T4, and T1<T2<T3<T4;

[0033] If T3≤T<T4, execute step S15;

[0034] If T≥T4, execute step S12;

[0035] S15, determining whether the total duration of the program is greater than the preset duration;

[0036] If yes, the custody process ends;

[0037] If not, execute step S11.

[0038] In order to ensure sufficient drying, the steps S2 and S3 are repeated n times, where n≤8.

[0039] In order to realize intelligent control, a controller is also included, which can receive the output signal of the humidity sensor and control the fan and the heating element accordingly according to the output signal.

[0040] In order to enable the hot air component to deliver hot air into the cavity, the air inlet duct has an air inlet and an air outlet, and an air inlet hole connected to the air outlet is opened on the side wall of the cavity.

[0041] The humidity sensor can be installed at a plurality of different positions. Preferably, the humidity sensor is installed on the air inlet duct of the hot air assembly or on the exhaust assembly of the dishwasher.

[0042] Compared with the prior art, the advantages of the present invention are: the intelligent cleaning storage control method of the dishwasher adopts staged cleaning storage, and can intelligently control the drying frequency of the hot air component according to the ambient humidity detected by the humidity sensor, which can not only avoid the phenomenon of moisture resorption, but also avoid frequent startup of the hot air component to affect the service life. The entire control process is highly intelligent, achieving the purpose of efficient cleaning storage and energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention is further described in detail below with reference to the accompanying drawings.

[0048] like Figures 1 to 3 As shown, the cleaning machine of this embodiment is a dishwasher, which includes a cavity 1, and a hot air component 2 is installed on the side wall of the cavity 1. The hot air component 2 has an air inlet duct 21 connected to the inside of the cavity 1, a heating element 22 and a fan 23 installed in the air inlet channel, the air inlet duct 21 has an air inlet 211 and an air outlet 212, and an air inlet hole 11 connected to the air outlet 212 is opened on the side wall of the cavity 1. An exhaust component 4 is installed on the door body 5, a humidity sensor 3 is installed on the exhaust component 4, and an exhaust port 51 connected to the air inlet of the exhaust component 4 is opened on the door body 5. The humidity sensor 3 is used to detect the external ambient temperature of the cavity 1. The controller (not shown in the figure) receives the output signal of the humidity sensor 3 and can control the fan 23 and the heating element 22 accordingly according to the output signal.

[0049] like Figure 4 As shown, the intelligent cleaning storage control method for the dishwasher can be divided into three stages. The first stage is started after the dishwasher finishes washing. In the first stage, the hot air component first works for a preset time, and then stops working for a preset time;

[0050] In the second stage, after the first stage, the humidity sensor performs humidity detection and compares the detected humidity value with the preset humidity value, and controls the preset working time and pause time of the hot air component according to different comparison results;

[0051] In the third stage, after the second stage, the humidity sensor performs humidity detection and compares the detected humidity value with the humidity preset value, and controls the preset working time and pause time of the hot air component accordingly according to different comparison results. Moreover, the humidity preset value of the second stage is smaller than the humidity preset value of the third stage, and the preset pause time of the hot air component in the second stage is smaller than the preset pause time of the third stage.

[0052] Specifically, the first stage includes the following steps:

[0053] S1, after the dishwasher finishes washing, it enters the first stage of storage;

[0054] S2, the hot air component starts and works for a preset time;

[0055] S3, the hot air component suspends operation for a preset time, and returns to step S2;

[0056] S4, open the drain valve;

[0057] S5. The first stage of custody ends and the second stage begins.

[0058] In the first stage, step S2 and step S3 are repeated n times, where n≤8. The function of opening the drain valve is to drain the condensed water inside the cavity 1.

[0059] The second phase includes the following steps:

[0060] S6, determining whether the humidity of the external environment of the cavity detected by the humidity sensor is higher than a preset value H1;

[0061] If yes, execute step S7;

[0062] If not, continue to step S6;

[0063] S7, preset working time of hot air component;

[0064] S8, hot air component pause time T;

[0065] S9, determining the relationship between the hot air component pause time T and the preset pause time T1 and T2;

[0066] If T1≤T<T2, proceed to step S10;

[0067] If T≥T2, execute step S7;

[0068] S10, determining whether the total duration of the program is greater than a preset duration;

[0069] If so, the second stage of custody ends and the third stage begins;

[0070] If not, execute step S6.

[0071] The third phase includes the following steps:

[0072] S11, determining whether the humidity of the external environment of the cavity detected by the humidity sensor is higher than a preset value H2, and H1<H2;

[0073] If yes, execute step S12;

[0074] If not, continue to execute step S11;

[0075] S12, preset working time of the hot air component;

[0076] S13, hot air component pause time T;

[0077] S14, determining the relationship between the hot air component pause time T and the preset pause time T3 and T4, and T1<T2<T3<T4;

[0078] If T3≤T<T4, execute step S15;

[0079] If T≥T4, execute step S12;

[0080] S15, determining whether the total duration of the program is greater than the preset duration;

[0081] If yes, the custody process ends;

[0082] If not, execute step S11.

[0083] It can be seen from the above control steps that in the second stage, if the humidity sensor detects that the humidity is higher than the preset value H1, the drying is turned on, and then it is paused for a preset time of at least T1. During this period, the humidity sensor works again. If the humidity is always lower than the preset value H1, in order to prevent the cavity from not being ventilated for too long, when the fan is paused for more than T2, the hot air component is turned on and the cycle continues until the end of the second stage of storage.

[0084] The logic of the third stage is the same as that of the second stage, except that at this time the cavity 1 is relatively dry, so the possibility of moisture resorption is reduced and the drying frequency can be appropriately reduced. In this embodiment, the purpose of reducing the drying frequency is achieved by increasing the humidity preset value H2 and extending the fan pause time T3~T4.
