[0027] The technical solutions in the embodiments of the present application will be introduced in combination with the drawings in the embodiments of the present application.

[0028] As Figure 1As shown, the current cleaning mode of the scrubber can be divided into cold water mode and steam mode. In the cold water mode, the boiler water pump and the boiler are in the closed state, the clean water in the clean water tank of the scrubber first flows through the flow meter into the first three-way joint, and then into the second three-way joint. The cleaning liquid pump synchronously extracts the cleaning agent in the cleaning liquid tank to the second three-way joint. The cleaning liquid and the clean water are fully mixed in the second three-way joint to form cleaning water. The cleaning water is extracted and pressurized by the cleaning water pump and then delivered to the water strip. The water strip sprays the cleaning water to the ground to complete the basic cleaning in the cold water mode. In the steam mode, the boiler water pump and the boiler are in the open state. The clean water in the clean water tank of the scrubber first flows through the flow meter into the first three-way joint and then flows to the boiler water pump. The boiler water pump delivers the clean water to the boiler. The boiler heats the clean water to make it boil and convert into high-temperature steam. The generated high-temperature steam is stabilized or divided after passing through the pressure relief valve with three-way function. Then the high-temperature steam is filtered by the filter screen and reaches the steam outlet through the steam delivery pipe. The high-temperature steam is sprayed out of the steam outlet. The high-temperature steam can be used to soften stubborn stains or high-temperature sterilization. However, in this working mode, the boiler needs to wait for the arrival of the clean water and also needs to heat the clean water from a lower temperature to a temperature that can boil and convert into high-temperature steam. It often takes a long time to generate high-temperature steam. Although the boiler capacity, heating power, water volume delivered by the boiler water pump during heating, or water delivery path of the water system can be designed to shorten the time for the boiler to generate steam, the user still needs to wait for a period of time before the steam is generated, which affects the user experience.

[0029] To solve the above technical problems, the embodiments of the present application provide a cleaning equipment control method, a cleaning equipment, a computer readable storage medium and a computer program product. Unlike the fixed process of only injecting water into the steam generator and heating in the steam mode in the traditional scheme, the idle or low-load time of the cleaning equipment in the non-steam mode (for example, only dust collection mode, only mopping mode, standby mode, charging mode or self-cleaning mode, etc.) is used to preheat the steam generator all day long. The real-time water temperature in the steam generator is always at a high temperature level, which can ensure that the steam generator can quickly heat up to the required temperature for generating steam based on a high temperature, shorten the heating time, and thus shorten the time for the steam generator to generate steam.

[0030] Figure 2 is a flowchart of a cleaning equipment control method provided by the embodiments of the present application, as Figure 2 shown, the method comprises the following steps.

[0031] S101, in the case that the cleaning equipment is in the non-steam mode, the real-time water temperature in the steam generator of the cleaning equipment is obtained.

[0032] The control method for cleaning equipment in this application embodiment is applied to cleaning equipment, which can be a device that uses a steam generator to generate high-temperature steam for cleaning, such as a floor scrubber, steam mop, or handheld steam cleaner. For convenience, a floor scrubber is used as an example of cleaning equipment.

[0033] Non-steam mode refers to the working mode of the cleaning equipment other than steam mode. Steam mode refers to the mode that relies on high-temperature steam generated by the steam generator to work, such as steam self-cleaning or high-temperature disinfection mode.

[0034] In one example, taking a floor scrubber as an example, the cleaning equipment includes standby mode, vacuuming / sweeping mode, mopping mode, silent / energy-saving mode, charging mode, pause mode, drying mode, error reporting mode, non-steam self-cleaning, steam mode, and steam self-cleaning. The non-steam mode includes standby mode, vacuuming / sweeping mode, mopping mode, silent / energy-saving mode, charging mode, pause mode, drying mode, error reporting mode, and non-steam self-cleaning. The steam mode and steam self-cleaning are classified as steam modes of the cleaning equipment. As you can understand, vacuuming / sweeping mode means the cleaning device only activates its own fan and roller brush for dry cleaning; mopping mode means the cleaning device wets the mop but does not heat it; silent / energy-saving mode means the cleaning device operates at low power; standby mode means the cleaning device is powered on but not performing a cleaning task, possibly remaining stationary or connected to the network; charging mode means the cleaning device is docked at a charging station to replenish its power; non-steam self-cleaning means the cleaning device only rinses its own roller brush and pipes with water; pause mode means the cleaning task of the cleaning device is temporarily interrupted; steam mode means the cleaning device uses a steam generator to produce and output high-temperature steam; steam self-cleaning means the cleaning device uses a steam generator to produce high-temperature steam to clean its own water tank and mop components; drying mode means the cleaning device dries its own mop; error mode means the cleaning device enters an error alarm state, such as disconnecting from the charging station or incorrectly connecting to the charging station.

[0035] The steam generator includes a temperature sensor, which can be a negative temperature coefficient thermistor (NTC), a positive temperature coefficient thermistor (PTC), or a thermocouple, etc. No specific limitation is made in the embodiments of this application. For convenience, an NTC temperature sensor is used as an example.

[0036] The cleaning equipment can detect its current operating mode in real time and determine whether it is in steam mode. If not, it determines that it is in non-steam mode and controls the temperature sensor to collect the water temperature in the steam generator, using this temperature as the real-time water temperature. The cleaning equipment can pre-store a steam set, which includes at least one operating mode belonging to steam mode. The cleaning equipment can determine whether it is in non-steam mode by checking whether the current operating mode exists in this steam set.

[0037] S102, if the real-time water temperature is not within the preheating temperature range, adjust the real-time water temperature to the preheating temperature range.

[0038] The preheating temperature range includes a first temperature threshold and a second temperature threshold. The first temperature threshold is less than the second temperature threshold, the first temperature threshold is greater than the preset temperature, and the second temperature threshold is less than the water temperature in the steam generator of the cleaning equipment in steam mode.

[0039] The preset temperature can be room temperature, such as 25℃ or 28℃.

[0040] The preheating temperature range can be a fixed temperature range pre-stored in the cleaning equipment, or it can be a temperature range dynamically determined by the cleaning equipment.

[0041] For example, when the preheating temperature range is a fixed temperature range, the first temperature threshold can be 45°C, 50°C or 60°C, etc., and the second temperature threshold can be 70°C, 85°C, 90°C or 97°C.

[0042] When the preheating temperature range is dynamically determined, the cleaning equipment can set a first temperature threshold based on the ambient temperature of its environment or the lowest water temperature in the steam generator under steam mode in a historical period (e.g., three months, one month, or one week). The cleaning equipment can set a second temperature threshold based on the altitude of the environment, the lowest water temperature in the steam generator under steam mode in a historical period, or the temperature at which scale is generated in the steam generator.

[0043] For example, when the ambient temperature is greater than or equal to room temperature, the cleaning equipment can use a first preset temperature (e.g., 40°C or 50°C) as the first temperature threshold. When the ambient temperature is lower than room temperature, a second preset temperature (e.g., 52°C or 60°C) can be used as the first temperature threshold. Since the first preset temperature is lower than the second preset temperature, a higher first temperature threshold can be set when the ambient temperature is cold, ensuring that the steam generator maintains a higher water temperature in cold environments. This shortens the steam output time when entering steam mode and avoids reduced heating efficiency of the steam generator due to excessive heat loss at low ambient temperatures, resulting in longer waiting times for users. Another example is that the cleaning equipment can set 50% or 55% of the lowest water temperature in the steam generator during a historical period as the first temperature threshold. The cleaning equipment can set a third preset temperature (e.g., 65°C or 70°C) as the second temperature threshold when the ambient altitude exceeds a preset altitude threshold (e.g., 1.5 km or 2 km), and a fourth preset temperature (e.g., 75°C or 97°C) as the second temperature threshold when the ambient altitude is less than or equal to the preset altitude threshold. The third preset temperature is lower than the fourth preset temperature. This avoids situations where the steam generator produces steam in non-steam mode due to a high temperature threshold setting at excessively high altitudes. For example, the cleaning equipment can set 70% or 80% of the lowest water temperature in the steam generator during a historical period in steam mode as the second temperature threshold. For example, if the temperature at which scale is generated in the steam generator is 80°C, a second temperature threshold can be set to 79°C. If the temperature at which scale is generated in the steam generator is 60°C, a second temperature threshold can be set to 59°C. Correspondingly, the first temperature threshold can be lowered, but the first temperature threshold is still guaranteed to be greater than the preset temperature. In this way, the time for the cleaning equipment to generate steam can be shortened while reducing the accumulation of scale in the steam generator.

[0044] In one implementation, when the real-time water temperature is greater than or equal to a first temperature threshold and less than a second temperature threshold, the cleaning device determines that the real-time water temperature is within a preset temperature range. The cleaning device then enters a low-power real-time water temperature detection cycle without needing to adjust the real-time water temperature of the steam generator. When the real-time water temperature is less than the first temperature threshold, or greater than or equal to the second temperature threshold, the cleaning device determines that the real-time water temperature is not within the preset temperature range. The cleaning device then controls the steam generator to cool down or heat up to adjust the real-time water temperature to the preset temperature range.

[0045] In one implementation, when the real-time water temperature is less than a first temperature threshold, the cleaning equipment controls the steam generator to heat up; when the real-time water temperature is greater than or equal to a second temperature threshold, the cleaning equipment controls the steam generator to cool down.

[0046] When the real-time water temperature is below a first temperature threshold, the cleaning equipment can activate the heating circuit of the steam generator to raise the temperature of the steam generator until the real-time water temperature of the steam generator is greater than or equal to the first temperature threshold. When the real-time water temperature is greater than or equal to a second temperature threshold, the cleaning equipment can deactivate the heating circuit of the steam generator, allowing the steam generator to cool naturally until the real-time water temperature of the steam generator is lower than the second temperature threshold. The heating circuit is typically controlled by a relay, and the cleaning equipment can activate or deactivate the heating circuit by controlling the closing of the relay. This implementation breaks down the complex temperature control of adjusting the real-time water temperature within a preset temperature range into a simpler control: heating when the temperature is below the lower limit (first temperature threshold) and cooling when the temperature reaches the upper limit (second temperature threshold). This saves energy consumption of the cleaning equipment and effectively prevents the water temperature from rising indefinitely, avoiding the evaporation of the steam-generating liquid in the steam generator due to excessive temperature in non-steam mode, thus improving the safety of the cleaning equipment.

[0047] In one implementation, when the real-time water temperature is greater than a second temperature threshold, the cleaning equipment can control the cooling of the steam generator through either active or passive cooling. In passive cooling, the cleaning equipment primarily relies on the natural cooling of the steam generator. It shuts off the heating circuit of the steam generator until the real-time water temperature falls below the second temperature threshold. In this method, while shutting off the heating circuit, the cleaning equipment continues to monitor the real-time water temperature within the steam generator. When the real-time water temperature is less than or equal to the second temperature threshold, cooling is considered complete, and the heating circuit remains off until a subsequent detection of a real-time water temperature below the first temperature threshold triggers the steam generator's heating operation.

[0048] During active cooling, the cleaning equipment can activate a steam pump to inject a cooler liquid, such as water, into the overheated steam generator. Through heat exchange between the hot and cold liquids, the water temperature inside the steam generator is rapidly reduced. Specifically, the cleaning equipment controls its own steam pump to supply the liquid to the steam generator until the real-time water temperature falls below a second temperature threshold, or until the water pump's replenishment time reaches a first preset duration. The replenishment time is the continuous duration for which the steam pump supplies the liquid to the steam generator.

[0049] The heating circuit is an electrical circuit that supplies power to the heating element (such as a heating tube) of the steam generator. It typically includes a power supply, switching devices (relays / silicon thyristors), the heating element itself, and connecting cables.

[0050] The steam-generating liquid is clean water, tap water, pure water, or softened water stored in the clean water tank of the cleaning equipment, which is used to generate steam.

[0051] The steam pump can deliver steam-generating liquid to the steam generator at a preset liquid supply rate. The preset liquid supply rate can be set according to the actual scenario, such as 6 ml / min or 5 ml / min. In this embodiment, no specific limitation is made. For convenience, 6 ml / min is used as an example.

[0052] The first preset duration can be set according to the liquid supply speed of the steam pump and the upper limit of the total liquid volume that the steam generator can hold. For example, the first preset duration can be 60s or 50s, etc. No specific limitation is made in this embodiment. For convenience, 60s is used as an example.

[0053] During the process of the steam pump supplying steam-generating liquid to the steam generator (also known as the water replenishment process), the cleaning equipment detects whether the real-time water temperature of the steam generator is lower than a second temperature threshold. If the real-time water temperature is lower than the second temperature threshold, the steam pump is immediately shut off to stop replenishing the steam generator with the lower-temperature steam-generating liquid, thus maintaining the real-time water temperature of the steam generator. Simultaneously, to prevent the steam-generating liquid from overflowing from the steam generator, in addition to checking whether the real-time water temperature is lower than the second temperature threshold during the water replenishment process, the cleaning equipment can also time the water replenishment duration of the steam pump. If the water replenishment duration is greater than or equal to a first preset duration, the steam pump is forcibly shut down. This prevents the steam pump from operating indefinitely due to temperature sensor malfunction or other abnormalities, which could lead to the steam generator overflowing, ensuring the safety of the steam generator. It can be understood that the cleaning equipment can control the steam pump to supply steam-generating liquid to the steam generator while simultaneously shutting off the heating circuit, thereby accelerating the cooling rate of the steam generator.

[0054] In the above technical solution, the steam generator can be cooled down by shutting off the heating circuit and / or controlling the steam pump to supply steam-generating liquid to the steam generator. This can compensate for the lag of simply cooling down by cutting off the power. The two measures work together to ensure that the real-time water temperature quickly drops back to the preset temperature range. At the same time, when the water replenishment time reaches the first preset time, regardless of whether the real-time water temperature is lower than the second temperature threshold, the supply of steam-generating liquid to the steam generator is stopped. This can prevent the steam generator from overflowing and improve the safety and adaptability of the steam generator temperature control.

[0055] To further prevent overflow of the steam generator during preheating (i.e., maintaining the real-time water temperature within a preset temperature range in non-steam mode), in one implementation, the steam generator includes a water level sensor. The system controls a steam pump in the cleaning equipment to supply steam-generating liquid to the steam generator. This includes: acquiring the real-time water level of the steam generator from the water level sensor; and, if the real-time water level is below a first water level threshold, controlling the steam pump in the cleaning equipment to supply steam-generating liquid to the steam generator at a preset supply rate.

[0056] The first water level threshold can be set according to the maximum liquid capacity that the steam generator can store, such as 80% or 90% of the maximum liquid capacity, etc., and this application embodiment does not impose specific limitations.

[0057] The water level sensor can be a float switch (providing trigger signals for high and low water levels), a capacitive water level sensor, an optical water level sensor, or a pressure sensor (calculating water level by calculating water pressure), etc., and no specific limitations are made in the embodiments of this application.

[0058] The real-time water level collected by the water level sensor can be a specific value (e.g., how many milliliters), level (e.g., high water level or low water level), or percentage (e.g., 80% or 70%) that represents the current water level of the steam generator. The corresponding first water level threshold can also be a specific value, level, or percentage that represents the water level. For example, the first water level threshold can be 15ml, 16ml, or 20ml, or it can be a high water level or 90%. This application does not impose specific limitations on the embodiments.

[0059] When the real-time water level in the steam generator is greater than or equal to the first water level threshold, the total liquid volume inside the steam generator is high. If steam-generating liquid continues to be supplied, it is highly likely that the water will overflow, or even backflow through the steam pipeline. In this case, the cleaning equipment can reduce the real-time water temperature of the steam generator by shutting off the heating circuit. When the real-time water level in the steam generator is less than the first water level threshold, there is space inside the steam generator to accommodate newly injected steam-generating liquid. The cleaning equipment can use a steam pump to supply steam-generating liquid to the steam generator for rapid cooling. Thus, by controlling the steam pump to supply steam-generating liquid to the steam generator only when the real-time water level is less than the first water level threshold, and by checking the water level before adding water, overflow failures caused by active cooling operations are prevented, protecting the internal circuitry and structural safety of the cleaning equipment.

[0060] In this embodiment, when the cleaning equipment is in non-steam mode, the real-time water temperature in the steam generator is adjusted to a temperature higher than a preset temperature, such as room temperature, but lower than the steam generation temperature. This enables preheating of the steam generator in operating modes other than steam mode. This ensures that the water temperature in the steam generator is always maintained at a higher temperature. In steam mode, the steam generator can quickly heat up from a higher base temperature to the temperature required to generate steam, shortening the heating time and thus reducing the steam generation time. This improves the steam generation speed of cleaning equipment, such as floor scrubbers, in steam mode.

[0061] Figure 3 This is a flowchart illustrating another control method for cleaning equipment provided in this application embodiment, as shown below. Figure 3 As shown, the method further includes the following step S201.

[0062] S201, when the cleaning equipment is in non-steam mode and the real-time water level in the steam generator is less than or equal to the second water level threshold, control the steam pump in the cleaning equipment to deliver steam-generating liquid to the steam generator until the total real-time liquid volume is greater than the second water level threshold.

[0063] The second water level threshold is less than the first water level threshold.

[0064] The second water level threshold can be set according to the maximum liquid capacity of the steam generator, such as 15%, 20% or 30% of the maximum liquid capacity. This application embodiment does not make specific limitations. For convenience, 20% of the maximum liquid capacity is taken as an example.

[0065] The cleaning equipment can detect the real-time water level in the steam generator using a water level sensor, or calculate the real-time water level by collecting the time and flow rate of the steam-generating liquid injected into the steam generator, as well as the time and flow rate of the high-temperature steam output from the steam generator, from a flow meter connected to the steam generator. When the real-time water level is less than or equal to a second water level threshold, regardless of whether the real-time water temperature is within a preset temperature range, the cleaning equipment will forcibly control the steam pump to deliver steam-generating liquid to the steam generator until the total real-time liquid volume exceeds the second water level threshold. This reduces the risk of dry burning or inability to support a single effective steam mode switch due to insufficient liquid volume in the steam generator, improving the safety of the cleaning equipment and the user experience. It can be understood that when the cleaning equipment forcibly controls the steam pump to deliver steam-generating liquid to the steam generator, the cleaning equipment can continue to execute S101 to preheat the steam generator even when the total real-time liquid volume exceeds the second water level threshold.

[0066] In one implementation, when the cleaning equipment is in steam mode and the real-time water level in the steam generator is less than or equal to a second water level threshold, the cleaning equipment is controlled to exit steam mode. Even while in steam mode, the cleaning equipment continues to monitor the real-time water level in the steam generator. If the real-time water level is less than or equal to the second water level threshold, it immediately exits steam mode to prevent dry burning. This means that when exiting steam mode, the cleaning equipment can continue to pump steam-generating liquid into the steam generator until the total real-time liquid volume exceeds the second water level threshold, allowing for the next steam mode switch or continued preheating of the steam generator.

[0067] In one application scenario, such as Figure 4As shown, when the floor scrubber (a cleaning equipment example) meets any of the following conditions (an example of being in non-steam mode): 1. From standby to operation, mode is automatic / silent / water suction; 2. After switching from operation (any mode), mode is automatic / silent / water suction; 3. Enter special mode; 4. Enter error message (on / off pile); 5. Enter drying (high speed / silent); 6. Enter self-cleaning pause; 7. Enter non-pile self-cleaning; 8. Enter charging. The floor scrubber can obtain the current temperature of its own boiler (a steam generator example) (an example of real-time water temperature). When the current temperature is less than 90℃ (an example of the first temperature threshold), the boiler water pump (an example of the steam water pump) is turned off, i.e., 0ml / min, to heat the boiler so that 90℃ ≤ current temperature < 97℃. If the current temperature is ≥97℃ (an example of the second temperature threshold), the boiler is cooled down. Specifically, the boiler water pump is turned on to add water to the boiler at a rate of 6ml / min, and the current temperature of the boiler is continuously monitored. If the current temperature of the boiler is <97℃ or the boiler water pump continues to add water for 60 seconds (an example of water addition time reaching the first preset time), the boiler water pump is turned off.

[0068] When the floor scrubber meets any of the following conditions (an example of being in steam mode): 1. Starting from standby mode, the mode is steam; 2. After switching between any modes, the mode is steam; 3. When entering steam self-cleaning mode, the floor scrubber is in steam mode. The boiler normally generates high-temperature steam, without performing any other operations on the boiler. Thus, by preheating the boiler by injecting water into it in non-steam mode, the boiler can directly heat the stored water when switching to steam mode, reducing water injection time, reducing heat loss, and allowing steam to quickly fill the pipes, thereby accelerating steam generation.

Figure 5 As shown, the cleaning device 100 includes: Temperature sensor 510 is used to detect the real-time water temperature of the steam generator 520 inside the cleaning equipment when the cleaning equipment is in non-steam mode, and to send the real-time water temperature to the processor. The processor 530 is used to adjust the real-time water temperature to the preheating temperature range when the real-time water temperature is not within the preheating temperature range. The preheating temperature range includes a first temperature threshold and a second temperature threshold. The first temperature threshold is less than the second temperature threshold. The first temperature threshold is greater than the ambient temperature of the environment where the cleaning equipment is located. The second temperature threshold is less than the water temperature in the steam generator of the cleaning equipment in steam mode.

[0072] In some embodiments, continue to combine Figure 5 The steam generator includes a water level sensor 521, which is used to collect the real-time water level of the steam generator and send the real-time water level to the processor. The processor is also used to control the steam pump 540 in the cleaning equipment to deliver steam-generating liquid to the steam generator at a preset liquid supply rate when the real-time water level is less than a first water level threshold.

[0073] In some embodiments, the second temperature threshold is determined based on the temperature at which scale is generated in the steam generator.

[0074] In some embodiments, when the cleaning equipment is in non-steam mode and the real-time water level in the steam generator is less than or equal to the second water level threshold, the processor is further configured to control the steam pump in the cleaning equipment to deliver steam-generating liquid to the steam generator until the real-time liquid volume is greater than the second water level threshold, and the second water level threshold is less than the first water level threshold.

[0075] In some embodiments, when the cleaning device is in steam mode and the real-time water level in the steam generator is less than or equal to a second water level threshold, the processor is also configured to control the cleaning device to exit steam mode.
