Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of cleaning equipment, and in particular to an intelligent storage control method of a cleaning machine. 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 can store tableware for a long time. After the existing dishwashers finish cleaning and enter the storage sequence, they mainly control the start and pause of the hot air component by time, that is, the humidity in the cavity is controlled by the hot air component, such as drying the tableware by hot air after washing, such as in the storage mode, by regularly (timing + time timing control) hot air circulation, reduce the risk of moisture re-entry, avoid odor, bacteria breeding, etc. The problem with the above hot air drying method is that the storage function of the existing dishwasher is often a fixed sequence, which is difficult to optimize the periodic sequence, and cannot cope with the change of seasons or the large temperature difference between day and night. The machine adopts a fixed sequence, and the storage function capacity is insufficient. The storage function is often a dishwasher with hot air / dehumidification function. The fixed sequence has high energy consumption and poor effect.

[0003] When the ambient humidity is very high, if the drying is still carried out at the inherent frequency, moisture may return between two drying cycles, affecting the user experience; when the ambient humidity is very low, moisture is relatively unlikely to return to the cavity. If the drying is still carried out at the original time, the drying frequency is too high, which has an adverse effect on the life of the hot air component and is not energy-saving and environmentally friendly. In addition, the humidity sensor of the dishwasher is an instrument that contains temperature and relative humidity information. It can calculate the current absolute humidity (the amount of water contained in the air per unit volume). This variable increases significantly with the increase in temperature, which means that the absolute humidity varies greatly at different temperatures, which also leads to condensation easily occurring when the temperature drops under high temperature and high humidity. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent storage control method for a cleaning machine capable of controlling the hot air component accordingly according to the temperature and humidity difference inside and outside the cavity in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: an intelligent storage control method of the cleaning machine, the cleaning machine 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 module and a fan arranged in the air inlet duct, and also includes an exhaust component connected to the inside of the cavity, characterized in that a humidity sensor that can detect both the external environmental temperature and relative humidity and the internal environmental temperature and relative humidity of the cavity is installed in the above exhaust component, and the intelligent storage control method includes the following steps:

[0006] S1. After washing is completed, the hot air component is started, and when the environment inside the cavity reaches a suitable state for storage, the hot air component is turned off;

[0007] S2, humidity sensor monitors the external ambient temperature and external relative humidity of the machine;

[0008] S3, the fan is turned on, and the humidity sensor detects the internal ambient temperature and internal relative humidity of the cavity;

[0009] S4, comparing the internal environment temperature obtained in step S3 with the external environment temperature obtained in step S2, and comparing the internal environment humidity obtained in step S3 with the external environment humidity obtained in step S2;

[0010] S5. According to the comparison result obtained in step S4, the working states of the heating module and the fan are controlled accordingly;

[0011] S6. Determine whether the total storage time is met;

[0012] If yes, proceed to step S7;

[0013] If not, return to step S2;

[0014] S7. End the storage sequence.

[0015] Preferably, the judgment logic of step S4 and step S5 is as follows:

[0016] 1) If the internal environment temperature is not greater than the external environment temperature, and the internal relative humidity is not greater than the external relative humidity, the fan does not work, and then enters step S6;

[0017] 2) If the internal environment temperature is not greater than the external environment temperature, and the internal relative humidity is greater than the external relative humidity, the fan works, the heating module does not work, and then enters step S6;

[0018] 3) If the internal environment temperature is greater than the external environment temperature, and the internal relative humidity is greater than the external environment humidity, the fan works and the heating module works; and then enters step S6;

[0019] 4) If the internal ambient temperature is greater than the external ambient temperature, and the internal relative humidity is not greater than the external relative humidity, then determine whether the external ambient temperature is high temperature or low temperature. If it is high temperature, it is a high temperature and high humidity environment, and both the fan and the heating module are working, and then enter step S6; if it is low temperature, it is a low temperature and high humidity environment, the fan is working and the heating module is not working, or both the fan and the heating module are not working, and then enter step S6.

[0020] More preferably, in the judgment logic 4), a temperature greater than 25° C. is considered a high temperature, and a temperature less than or equal to 25° C. is considered a low temperature.

[0021] Further preferably, in the judgment logic 3), the continuous working time of the fan is 3 to 6 hours.

[0022] Further preferably, in the judgment logic 4), the continuous working time of the fan is 0.5 to 1 hour.

[0023] In order to realize intelligent control, a controller is also included. The controller can receive the output signal of the humidity sensor and can control the fan and the heating module accordingly according to the output signal.

[0024] 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.

[0025] The humidity sensor can be installed in multiple different positions. Preferably, the exhaust assembly is installed on the door body of the cleaning machine. The exhaust assembly has an exhaust channel connecting the inside of the cavity with the outside of the cavity, and the humidity sensor is installed in the exhaust channel.

[0026] In order to enable the humidity sensor to accurately detect the temperature and humidity of the external environment, the humidity sensor is adjacent to the outlet of the exhaust passage.

[0027] Compared with the prior art, the advantages of the present invention are: a humidity sensor that can detect both the external ambient temperature and relative humidity and the internal ambient temperature and relative humidity of the cavity is installed in the exhaust component of the intelligent storage control method of the cleaning machine. The humidity sensor compares the internal and external ambient humidity and the internal and external relative humidity to intelligently control the fan and the heating module. The control method can identify periodic changes in the environment and optimize the storage sequence accordingly for different environments. It has a high degree of intelligence and achieves the purpose of efficient cleaning storage and energy saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 3 As shown, the cleaning machine of this embodiment 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 module 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 3 is installed on the door body 5 of the cleaning machine, and the exhaust component 3 has an exhaust channel 31 connecting the inside of the cavity 1 with the outside of the cavity 1, and an exhaust port 51 connected to the exhaust channel 31 is opened on the door body 5. The humidity sensor 4 is installed in the exhaust channel 31 and adjacent to the outlet of the exhaust channel 31. The humidity sensor 4 can detect both the external environmental temperature and relative humidity, and the humidity of the internal environmental temperature and relative humidity of the cavity 1. The controller (not shown in the figure) can receive the output signal of the humidity sensor 4, and can control the fan 23 and the heating module 22 accordingly according to the output signal.

[0034] like Figure 4 As shown, the intelligent storage control method of the cleaning machine includes the following steps:

[0035] S1. After washing is completed, the hot air component 2 is started, and when the environment inside the cavity 1 reaches a suitable state for storage, the hot air component 2 is turned off;

[0036] S2, humidity sensor 4 monitors the external ambient temperature and external relative humidity of the machine;

[0037] S3, the fan 23 is turned on, and the humidity sensor 4 detects the internal ambient temperature and internal relative humidity of the cavity 1;

[0038] S4, comparing the internal environment temperature obtained in step S3 with the external environment temperature obtained in step S2, and comparing the internal environment humidity obtained in step S3 with the external environment humidity obtained in step S2;

[0039] S5, according to the comparison result obtained in step S4, the working state of the heating module 22 and the fan 23 is controlled accordingly;

[0040] S6. Determine whether the total storage time is met;

[0041] If yes, proceed to step S7;

[0042] If not, return to step S2;

[0043] S7. End the storage sequence.

[0044] Among them, in step S1, the cavity 1 is first dried. Meeting the suitable environment for storage means that the machine reaches a relatively "dry state" with as little water as possible visible to the naked eye.

[0045] The judgment logic of step S4 and step S5 is as follows:

[0046] 1) If the internal ambient temperature is not greater than the external ambient temperature, and the internal relative humidity is not greater than the external relative humidity, the fan 23 does not work, and then enters step S6; in this environment, if the fan 23 is turned on, the humidity inside the cavity will increase. Therefore, there is no need to turn on the fan 23 at this time, and it is only necessary to keep the air from circulating.

[0047] 2) If the internal ambient temperature is not greater than the external ambient temperature, and the internal relative humidity is greater than the external relative humidity, the fan 23 works, the heating module 22 does not work, and then enters step S6; in this environment, if the heating module 22 is turned on, the air entering the cavity 1 from the outside will condense on the side wall of the cavity 1, thereby returning to moisture. Therefore, blowing cold air at this time can reduce the humidity.

[0048] 3) If the internal ambient temperature is greater than the external ambient temperature, and the internal relative humidity is greater than the external ambient humidity, the fan 23 works and the heating module 22 works; and then enters step S6; in this environment, the interior of the cavity 1 is a high temperature and high humidity environment, and condensation is easy to occur inside the cavity 1, so hot air is continuously blown until the next judgment cycle.

[0049] 4) If the internal environment temperature is higher than the external environment temperature, and the internal relative humidity is not higher than the external relative humidity, then determine whether the external environment temperature is high or low. If it is high, it is a high temperature and high humidity environment, and the fan 23 and the heating module 22 are both working, and then enter step S6; if it is low temperature, it is a low temperature and high humidity environment, and the fan 23 is working and the heating module 22 is not working, and then enter step S6. Since the amount of saturated steam water at different temperatures is different, in this environment, it is necessary to distinguish between high and low temperatures in the external environment. It is recommended to blow hot air at high temperatures and cold air at low temperatures, so as to improve condensation; such judgment cycles are continuously iterated until the entire storage period is met.

[0050] In the above judgment logic, in judgment logic 3), the continuous working time of the fan 23 is 3 to 6 hours. In judgment logic 4), the continuous working time of the fan 23 is 0.5 to 1 hour, and a temperature greater than 25°C is considered high temperature, and a temperature less than or equal to 25°C is considered low temperature.

[0051] like Figure 4As shown, in the above judgment logic 4), in the low temperature and high humidity environment, the fan 23 works and the heating module 22 does not work, that is, cold air is blown. In addition, in the low temperature and high humidity environment, the fan 23 and the heating module 22 may not work, that is, no air is blown, which can also improve the condensation effect.
