For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0053] In the description of this disclosure, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0054] To enable those skilled in the art to better understand this disclosure, a brief description of the cleaning equipment and its system architecture involved in this disclosure will first be given with reference to Figure 1.

[0055] Referring to Figure 1, a system architecture diagram of a cleaning device according to some embodiments of the present disclosure is shown. As shown in Figure 1, a cleaning device system architecture in one embodiment is illustrated, which includes a liquid tank 101, a liquid detection device 102, a first three-way valve 103, a detergent tank 104, a detergent pump 105, a second three-way valve 106, a heater liquid pump 107, a pressure relief valve 108, a heater 109 (e.g., a boiler), a filter screen 110, a first reversing valve 111, a steam port 112, a liquid pump 113, a second reversing valve 114, a third three-way valve 115, and cleaning components 116 (e.g., a cleaning roller brush, a mop).

[0056] In some embodiments, the liquid tank 101 is used to store liquid, which can be clean water or other liquids that can clean the floor or cleaning components; this disclosure does not specifically limit this. The liquid detection device 102 (e.g., a flow meter, level gauge, etc.) can be used to detect the liquid flow rate in the liquid pipeline and to determine whether the liquid in the pipeline is sufficient. The heater liquid pump 107 is used to pump a set flow rate of liquid into the heater 109, so that the heater 109 heats the liquid to generate steam, which flows through the first reversing valve 111 to the steam nozzle 112, and finally sprays the steam onto the ground. The liquid pump 113 can pump a larger set flow rate of liquid into the heater 109 through the second reversing valve 114, so that the heater 109 heats the liquid to generate a hot liquid at a higher temperature. The generated hot liquid then flows through the first reversing valve 111 to the cleaning component 116 to clean the floor or wash the cleaning component. Liquid pump 113 can directly pump a cool liquid (or room temperature liquid) to cleaning component 116 through second reversing valve 114 to clean the floor or wash the cleaning component.

[0057] In this embodiment, the first reversing valve 111 and the second reversing valve 114 are used to switch the flow path of the liquid in the liquid pipeline to adapt to different functional modes of the cleaning equipment. In the cleaning equipment of this embodiment, the liquid flow path may include flow path A, flow path B, and flow path C, which are used by the cleaning equipment to perform cleaning tasks in cold liquid mode, hot liquid mode, and steam mode, respectively. In addition, the cleaning equipment also includes flow path D, in which the cleaning agent pump 105 pumps the cleaning agent in the cleaning agent tank 104 into the second three-way valve 106 to deliver the cleaning agent to the entire liquid pipeline.

[0058] In some embodiments, in the cold liquid mode, the second reversing valve 114 is closed, and the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the second three-way valve 106, the liquid pump 113, the second reversing valve 114, the third three-way valve 115, and the cleaning component 116. Since the liquid is not heated by the heater 109, the liquid flowing to the cleaning component 116 is in a low-temperature liquid state (e.g., a room-temperature liquid state).

[0059] In hot liquid mode, both the first reversing valve 111 and the second reversing valve 114 are open. The liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the second three-way valve 106, the liquid pump 113, the second reversing valve 114, the pressure relief valve 108, the heater 109, the filter screen 110, the first reversing valve 111, the third three-way valve 115, and the cleaning component 116. Because the liquid is heated by the heater 109, the liquid flowing to the cleaning component 116 is in a high-temperature liquid state, which enhances the cleaning effect on the floor or the cleaning component.

[0060] In steam mode, the first reversing valve 111 is closed, and the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the heater liquid pump 107, the pressure relief valve 108, the heater 109, the filter screen 110, the first reversing valve 111, and the steam port 112. Because the liquid is heated by the heater liquid pump 107 and the heater 109, the liquid flowing to the steam port 112 is in a high-temperature gaseous state, which enhances the cleaning effect on the ground.

[0061] In practical applications, cleaning equipment uses a liquid pump to supply liquid to the cleaning components when cleaning floors, which wets the components and facilitates the removal of stains. Cleaning equipment with a steam mode sprays steam onto the floor, which softens solid stains for easier cleaning and kills microorganisms at high temperatures. Therefore, it can significantly improve the cleaning effect. However, ensuring stable steam generation and reliable cleaning performance in steam mode is crucial. In this regard, this disclosure proposes several embodiments of a cleaning equipment and its control method to guarantee the reliability of the cleaning equipment in steam mode.

[0062] The implementation details of the technical solutions in the embodiments of this disclosure will be described in detail below.

[0063] Before proceeding, it should be noted that, to enable those skilled in the art to better understand this disclosure, some embodiments including control parameters will be provided. In these embodiments, the specific values ​​of the control parameters are given with reference to the assumption that the liquid is pure water. For the sake of brevity, this disclosure will not elaborate on this further in the subsequent description. Furthermore, the specific values ​​of the control parameters in the embodiments are merely exemplary; in practical applications, the control parameters in the embodiments may also be other values ​​depending on the actual situation.

[0064] Referring to FIG2, a structural schematic diagram of a cleaning device according to some embodiments of the present disclosure is shown.

[0065] Referring to FIG2, the cleaning device 100 disclosed herein may include a heater 109, a heater liquid pump 107, a temperature detection device 117, and a controller 300.

[0066] In some embodiments, heater 109 may be configured to heat liquid to generate steam; heater liquid pump 107 is connected to heater 109 and may be configured to supply liquid to heater 109; temperature detection device 117 is disposed on heater 109 and may be configured to collect heater temperature; controller 300 is communicatively connected to heater 109, heater liquid pump 107, and temperature detection device 117.

[0067] Referring again to Figure 2, in this disclosure, the controller 300 can be configured to: in steam mode, acquire the heater temperature collected by the temperature detection device 117; if the heater temperature falls into a first temperature range, control the heater liquid pump 107 to supply liquid to the heater 109 at a first flow rate; if the heater temperature falls into a second temperature range, control the heater liquid pump 107 to supply liquid to the heater 109 at a second flow rate, wherein the second temperature range and the first temperature range are adjacent temperature ranges, and the minimum temperature of the second temperature range is greater than the maximum temperature of the first temperature range, and the second flow rate is greater than the first flow rate.

[0068] In this disclosure, the temperature detection device 117 may be a negative temperature coefficient thermistor (NTC), a thermocouple, an infrared temperature sensor (ITS), a semiconductor temperature sensor (STS), or a bimetallic temperature sensor (BTS), and this disclosure does not specifically limit it.

[0069] In this disclosure, the first temperature range can be [97 degrees, 99 degrees), [98 degrees, 99 degrees), or [99 degrees, 100 degrees]. It should be understood that the first temperature range can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0070] In some embodiments, the second temperature range can be [98 degrees, +∞ degrees), [99 degrees, +∞ degrees), or [100 degrees, +∞ degrees). It should be understood that the second temperature range can be set according to actual needs, and this disclosure does not specifically limit it.

[0071] In some embodiments, the first flow rate can be in the range of 1.9-2.1 ml / min; for example, the first flow rate can be 1.8 ml / min or 1.9 ml / min. It should be understood that the first flow rate can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0072] Referring again to Figure 2, in some embodiments, the step of controlling the heater liquid pump to supply liquid to the heater at a second flow rate if the heater temperature falls into the second temperature range includes: if the heater temperature falls into the second temperature range, increasing the set flow rate amplitude based on the first flow rate to obtain the second flow rate, and controlling the heater liquid pump to supply liquid to the heater at the second flow rate, wherein the set flow rate amplitude is positively correlated with the value by which the heater temperature exceeds the minimum temperature in the second temperature range.

[0073] In some embodiments, after the heater temperature falls into the second temperature range, the set flow rate amplitude can be increased by a certain amount for every 1 degree Celsius the heater temperature exceeds the minimum temperature in the second temperature range. For example, when the second temperature range is [98 degrees Celsius, +∞ degrees Celsius), the first flow rate is 1.8 ml / min. When the heater temperature exceeds 98 degrees Celsius by 1 degree (i.e., the heater temperature is 99 degrees Celsius), the set flow rate amplitude is 0.4 ml / min, meaning the second flow rate is 2.2 ml / min. When the heater temperature exceeds 98 degrees Celsius by 2 degrees (i.e., the heater temperature is 100 degrees Celsius), the set flow rate amplitude is 0.8 ml / min, meaning the second flow rate is 2.6 ml / min. When the heater temperature exceeds 98 degrees Celsius by 3 degrees (i.e., the heater temperature is 101 degrees Celsius), the set flow rate amplitude is 1.2 ml / min, meaning the second flow rate is 3 ml / min. When the heater temperature exceeds 98 degrees by a factor of 4 (i.e., the heater temperature is 102 degrees), the set flow rate amplitude is 2.7 ml / min, meaning the second flow rate is 4.5 ml / min. When the heater temperature exceeds 98 degrees by a factor of 5 or more (e.g., the heater temperature is 103 degrees), the set flow rate amplitude is 3.2 ml / min, meaning the second flow rate is 5 ml / min.

[0074] In some embodiments, after the heater temperature falls into the second temperature range, the set flow rate amplitude can be increased by 0.2 ml / min for every 1 degree Celsius the heater temperature exceeds the minimum temperature in the second temperature range. For example, when the second temperature range is [99 degrees Celsius, +∞ degrees Celsius), and the corresponding first flow rate is 2 ml / min, if the heater temperature is 100 degrees Celsius, the set flow rate amplitude is 0.2 ml / min, i.e., the second flow rate is 2.2 ml / min; if the heater temperature is 101 degrees Celsius, the set flow rate amplitude is 0.4 ml / min, i.e., the second flow rate is 2.4 ml / min. It should be understood that, under the logic that the set flow rate amplitude is positively correlated with the value by which the heater temperature exceeds the minimum temperature in the second temperature range, the set flow rate amplitude increased based on the first flow rate can be set according to actual needs, and this disclosure does not specifically limit it in this way.

[0075] In some embodiments, it should be noted that if the heater temperature returns from the second temperature range to the first temperature range, the heater liquid pump 107 in the cleaning device 100 can continue to supply liquid to the heater 109 at the first flow rate.

[0076] Based on the technical solution proposed in this disclosure, the cleaning equipment can stably generate steam by dynamically adjusting the flow rate of liquid supplied to the heater by the heater liquid pump in real time, thereby ensuring the reliability of the cleaning equipment in steam mode. In some embodiments, when the heater temperature falls into a first temperature range, the liquid flow rate of the heater liquid pump is automatically controlled at a first flow rate to ensure normal operation of the steam mode. Once the temperature exceeds the first temperature range, i.e., the temperature rises and falls into a second temperature range, the heater liquid pump 107 is controlled to supply liquid to the heater 109 at a second flow rate greater than the first flow rate to balance the heat generated by the heater 109, thereby effectively reducing the heater temperature to the first temperature range. Therefore, through this adaptive flow regulation mechanism, the heater temperature can be kept stable, preventing overheating of the heater from causing equipment failure or safety hazards. The stability of the heater temperature enhances the uniformity of steam production, thereby improving the cleaning effect of the cleaning equipment on the ground in steam mode and ensuring the efficiency and quality of the cleaning equipment in performing cleaning tasks. In addition, this flow regulation mechanism also helps to save energy, extend the service life of components in the cleaning equipment, and reduce maintenance costs, thereby improving the overall reliability and economy of the cleaning equipment.

[0077] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: if the heater temperature falls into a fifth temperature range, control the heater liquid pump 107 to intermittently supply liquid to the heater 109, wherein the fifth temperature range and the first temperature range are adjacent temperature ranges, and the maximum temperature of the fifth temperature range is less than the minimum temperature of the first temperature range.

[0078] In some embodiments, the fifth temperature range may include a plurality of temperature sub-ranges connected in sequence.

[0079] Referring again to Figure 2, in some embodiments, controlling the heater liquid pump to intermittently supply liquid to the heater if the heater temperature falls into a fifth temperature range includes: if the heater temperature falls into a first temperature sub-range, controlling the heater liquid pump to supply liquid to the heater at a third flow rate, the third flow rate being less than the first flow rate; if the heater temperature falls into a second temperature sub-range, controlling the heater liquid pump to stop supplying liquid to the heater, wherein the first temperature sub-range and the second temperature sub-range are any two adjacent temperature sub-ranges among the plurality of temperature sub-ranges.

[0080] In some embodiments, the length of the temperature sub-interval can be greater than a first length threshold and less than a second length threshold. For example, the first length threshold can be 5 degrees and the second length threshold can be 15 degrees. It should be understood that the first length threshold and the second length threshold can be set according to actual needs, and this disclosure does not specifically limit them.

[0081] In some embodiments, the interval lengths of the various temperature sub-intervals may be the same or different.

[0082] To enable those skilled in the art to better understand this disclosure, a specific example will be used to illustrate this instance below.

[0083] In this specific example, the fifth temperature range can be [30 degrees, 98 degrees), and the third flow rate can be 1.4 ml / min. Based on this, the heater liquid pump 107 can be controlled to intermittently supply liquid to the heater 117 according to the third flow rate, according to the control logic in Table 1 below.

[0084] Table 1

[0085] In this embodiment, by introducing temperature sub-ranges and liquid flow regulation logic into the heater liquid supply logic, the reliability of the cleaning equipment in performing cleaning tasks in steam mode can be significantly improved.

[0086] In some embodiments, by setting reasonable temperature sub-ranges and intermittent liquid supply, when the heater temperature is in the lower fifth temperature range, the heater liquid pump 107 is controlled to intermittently supply liquid to the heater 109 at a lower third flow rate. This can accelerate the steam generation rate and effectively prevent the liquid in the heater 109 from rapidly evaporating and causing the heater 109 to dry-burn during periods when the liquid supply is stopped. This reduces the risk of heater 109 failure due to overheating, extends the service life of the heater 109 and related components, and reduces the maintenance and replacement costs of the cleaning equipment.

[0087] In some embodiments, the length of the temperature sub-interval is set to a reasonable range, which can avoid the situation where the temperature detection device 117 collects the heater temperature inaccurately due to the temperature sub-interval length being too small, and can also avoid the situation where the heater 109 burns dry during the period when the liquid supply is stopped due to the rapid evaporation of liquid and insufficient supply due to the temperature sub-interval length being too large. This can ensure the safety and reliability of the cleaning equipment in performing cleaning tasks in steam mode.

[0088] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: if the heater temperature falls into the sixth temperature range, control the heater liquid pump 107 to stop supplying liquid to the heater 109, wherein the sixth temperature range and the fifth temperature range are adjacent temperature ranges, and the maximum temperature of the sixth temperature range is less than the minimum temperature of the fifth temperature range.

[0089] In some embodiments, the sixth temperature range can be (-∞ degrees, 30 degrees). If the heater temperature falls into the sixth temperature range, the liquid pump 107 is controlled to stop supplying liquid to the heater 109. This ensures that the liquid in the heater 109 can quickly accumulate heat, thereby achieving a rapid heating effect.

[0090] Referring again to FIG2, in some embodiments, the cleaning device 100 may further include a liquid pump 113. The liquid pump 113 is connected to the heater 109 and may be configured to supply liquid to the heater 109. In some embodiments, the flow rate of liquid supplied by the liquid pump 113 to the heater 109 is greater than the flow rate of liquid supplied by the heater liquid pump 107 to the heater 109.

[0091] In some embodiments, the controller 300 may also be configured to: control the liquid pump 113 to supply liquid to the heater 109 in response to the cleaning device 100 being triggered to enter steam mode; and after the liquid pump 113 has been supplying liquid to the heater 109 for a first duration, control the liquid pump 113 to stop supplying liquid to the heater 109 and control the heater 109 to operate.

[0092] In practical applications, the controller 300 can control the cleaning device 100 to enter steam mode after receiving a control command triggered by the user to enter steam mode. When the cleaning device 100 enters steam mode, the controller 300 can control the second reversing valve 114 as shown in Figure 1 to be in the open state. Afterwards, the controller 300 can control the liquid pump 113 in the cleaning device 100 to supply liquid to the heater 109.

[0093] In some embodiments, the first duration can be in the range of 3-8 seconds; for example, the first duration can be 5 seconds or 6 seconds. It should be understood that the first duration can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0094] In some embodiments, it is understood that when the cleaning device 100 enters the steam mode, if the controller 300 does not control the liquid pump 113 to supply liquid to the heater 109 for cooling, the initial temperature of the heater 109 may be at a high level, which may quickly trigger the self-protection mechanism of the heater 109 (i.e., the heater 109 operates at a lower power (e.g., 145 watts)). This results in less heat being generated by the heater 109, and the liquid in the heater 109 cannot quickly produce steam due to its low heat absorption rate.

[0095] By controlling the liquid pump 113 to continuously supply liquid to the heater 109 for a certain period of time, and given the high operating power of the liquid pump 113 (e.g., 10V, 15V), a large flow rate of liquid can be supplied to the heater 109. This allows the heater temperature to be cooled to a certain temperature that is less likely to trigger the heater 109's self-protection mechanism. This allows the heater 109 to operate at a higher power (e.g., 285 watts) for a longer period, enabling the liquid in the heater 109 to absorb more heat in a short time, increasing the rate and magnitude of temperature change. This, in turn, facilitates the rapid generation of steam in the heater 109, achieving a rapid steam production effect. Therefore, the response speed of the cleaning equipment 100 in steam mode can be improved, ensuring the reliability of the cleaning equipment 100 in performing cleaning tasks in steam mode, thereby enhancing the user experience. Continuing to refer to Figure 2, in some embodiments, the cleaning equipment 100 may also include a cleaning component 116, with the liquid pump 113 connected to the cleaning component 116. The cleaning component 116 can be configured to clean the floor.

[0096] In some embodiments, the controller 300 may also be configured to: after controlling the liquid pump 113 to stop supplying liquid to the heater 109 and controlling the heater 109 to run, if the heater 109 continues to run for a second duration and the heater temperature is greater than or equal to a first temperature, then control the second reversing valve 114 as shown in FIG1 to be closed, so as to control the liquid pump 113 to supply liquid directly to the cleaning unit 116; if the heater temperature is less than the first temperature, then control the cleaning equipment 100 to issue a prompt message indicating that steam preparation is in progress.

[0097] In some embodiments, the value range of the second duration can be 15-25 seconds; for example, the second duration can be 20 seconds or 22 seconds. It should be understood that the second duration can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0098] In some embodiments, the first temperature may be in the range of 85-95 degrees Celsius; for example, the first temperature may be 90 degrees Celsius or 92 degrees Celsius. It should be understood that the first temperature can be set according to actual needs, and this disclosure does not impose any specific limitations on it.

[0099] In some embodiments, after the liquid pump 113 stops supplying liquid to the heater 109, if the duration of operation of the heater 109 meets the second duration and the heater temperature is greater than or equal to the first temperature, it can be considered that the heater 109 has the steam production capability, and the produced steam can meet the cleaning requirements. At this time, controlling the liquid pump 113 to directly supply liquid to the cleaning component 116 of the cleaning device 100 can enable the cleaning device 100 to perform cleaning tasks in steam mode and also in cold liquid mode, thereby enhancing the cleaning capability of the cleaning device 100, ensuring the reliability of the cleaning device 100 in performing cleaning tasks, and improving the user experience.

[0100] In some embodiments, if the heater temperature is lower than a first temperature after the liquid pump 113 stops supplying liquid to the heater 109, it indicates that the heater 109 is not yet able to generate steam within a short period of time. In this case, by controlling the cleaning device 100 to issue a prompt message indicating that steam preparation is in progress, the user can be reminded to wait, avoiding the user's mistaken belief that the cleaning device 100 has malfunctioned, thereby improving the user experience.

[0101] Referring again to Figure 2, in some embodiments, the cleaning device 100 further includes a liquid detection device 102. The liquid detection device 102 may be configured to detect whether there is flowing liquid in the liquid line of the cleaning device 100; the controller 300 may also be configured to: if the duration of flowing liquid in the liquid line of the cleaning device 100 meets a third duration, control the heater liquid pump 107 to supply liquid to the heater 109; if the duration of no flowing liquid in the liquid line meets a fourth duration, control the heater liquid pump 107 to stop supplying liquid to the heater 109.

[0102] In some embodiments, the fourth duration may be less than the third duration.

[0103] In some embodiments, a liquid detection device 102 may be provided in the liquid pipeline of the cleaning equipment 100 to detect whether there is flowing liquid in the liquid pipeline of the cleaning equipment 100. In some embodiments, the liquid detection device 102 may be a flow meter or a level gauge, and this disclosure does not specifically limit it.

[0104] In some embodiments, the value range of the third duration can be 1.5-2.5 seconds; for example, the third duration can be 2 seconds or 2.2 seconds. The value range of the fourth duration can be 0.5-1.5 seconds; for example, the fourth duration can be 1 second or 1.2 seconds. It should be understood that the third duration and the fourth duration can be set according to actual needs, and this disclosure does not impose specific limitations on them.

[0105] In some embodiments, if there is no continuously flowing liquid in the liquid line of the cleaning device 100 within a fourth time period, an alarm can be issued to remind the user to add liquid to the cleaning device 100 in a timely manner.

[0106] In this disclosure, on the one hand, after the cleaning equipment 100 enters steam mode, by detecting the liquid in the liquid pipeline of the cleaning equipment 100 and controlling the liquid supply delay, it is possible to effectively prevent the heater liquid pump 107 from starting when there is no liquid or insufficient liquid in the liquid pipeline, thus preventing the heater 109 from starting and avoiding damage to components or safety accidents caused by the heater 109 burning out. On the other hand, based on the confirmation that there is liquid flow in the liquid pipeline, by delaying the control of the heater liquid pump 107 to supply liquid to the heater 109 for a third time period, it is possible to ensure that the liquid flows stably to the heater 109, thereby avoiding the situation where the heater 109 burns out due to unstable liquid flow or incomplete liquid flow in the liquid pipeline. Therefore, this disclosure can improve the operational safety, operational reliability, and service life of the cleaning equipment 100 in steam mode.

[0107] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: after the cleaning device 100 exits the steam mode, control the heater liquid pump 107 to supply liquid to the heater 109 for a certain period of time.

[0108] In some embodiments, the duration for which the heater liquid pump 107 supplies liquid to the heater 109 after the cleaning device 100 exits the steam mode can be in the range of 1-10 seconds; for example, it can be 5 seconds or 5.5 seconds. It should be understood that this duration can be set according to actual needs, and this disclosure does not specifically limit it.

[0109] In some embodiments, after the cleaning equipment 100 exits the steam mode to perform the cleaning task, by controlling the heater liquid pump 107 to continuously supply liquid to the heater 109 for a certain period of time, the heater 109 can be cooled down quickly, avoiding damage to the components in the cleaning equipment 100 due to the heater 109 being too hot, thereby improving the service life of the cleaning equipment 100.

[0110] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: if the heater temperature falls into a third temperature range, control the heater 109 to operate at a first power; if the heater temperature falls into a fourth temperature range, control the heater 109 to operate at a second power, wherein the fourth temperature range and the third temperature range are adjacent temperature ranges, and the minimum temperature of the fourth temperature range is greater than the maximum temperature of the third temperature range, and the second power is less than the first power.

[0111] In some embodiments, the third temperature range can be (-∞ degrees, 96 degrees), (-∞ degrees, 97 degrees), or (-∞ degrees, 98 degrees). It should be understood that the third temperature range can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0112] In some embodiments, the fourth temperature range can be [96 degrees, 104 degrees), [97 degrees, 104 degrees), or [98 degrees, 104 degrees]. It should be understood that the fourth temperature range can be set according to actual needs, and this disclosure does not specifically limit it.

[0113] In some embodiments, the first power can be in the range of 275-300 watts; for example, the first power can be 285 watts or 280 watts. It should be understood that the first power can be set according to actual needs, and this disclosure does not specifically limit it.

[0114] In some embodiments, the value range of the second power can be 135-170 watts; for example, the second power can be 145 watts or 140 watts. It should be understood that the second power can be set according to actual needs, and this disclosure does not specifically limit it.

[0115] In some embodiments, by monitoring the heater temperature in real time and dynamically adjusting the heater's operating power according to the temperature range, it can be ensured that the heater temperature remains within a safe and efficient operating range. In some embodiments, if the heater temperature falls into a lower third temperature range, controlling the heater to operate at a higher first power allows the liquid in the heater to absorb more heat, increasing the rate and magnitude of temperature change. This facilitates rapid steam generation, improving the response speed of the cleaning equipment in steam mode and ensuring the reliability of cleaning tasks, thereby enhancing the user experience. If the heater temperature falls into a higher fourth temperature range, controlling the heater to operate at a lower second power allows for a stable and sufficient steam production. This prevents excessive evaporation of the liquid due to excessive heat absorption at high temperatures and reduces the risk of dry burning caused by rapid evaporation. Therefore, it improves the operational safety, reliability, and lifespan of the cleaning equipment in steam mode.

[0116] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to control the heater 109 to operate at a second power if the duration of operation of the heater 109 at the first power is greater than or equal to the fifth duration.

[0117] In some embodiments, the fifth duration can be in the range of 55-65 seconds; for example, the fifth duration can be 60 seconds or 58 seconds. It should be understood that the fifth duration can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0118] In some embodiments, if the heater temperature remains in the third temperature range for an excessively long period, one possible reason is a large volume of liquid in the heater 109. Even if the heater temperature does not fall into the fourth temperature range, the liquid in the heater 109 absorbs a significant amount of heat due to the heater 109 operating at a higher power for a longer period, resulting in sufficient steam generation. By reducing the first power to the second power, energy can be effectively saved, the power consumption of the heater 109 reduced, and the operating pressure and heat load of the heater 109 decreased. Therefore, this not only helps extend the service life of the heater 109 but also improves its overall efficiency. Another possible reason is a malfunction or abnormality of the temperature detection device 117. In this case, if the heater 109 operates at the first power for a duration greater than or equal to the fifth duration, controlling the heater 109 to operate at the second power can effectively prevent inaccurate heater temperature detection due to a malfunction or abnormality of the temperature detection device 117, which could lead to an excessively high actual temperature of the heater 109 and damage to the device.

[0119] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: if the heater temperature falls into the seventh temperature range, control the heater 109 to stop operating, wherein the seventh temperature range and the fourth temperature range are adjacent temperature ranges, and the minimum temperature of the seventh temperature range is greater than the maximum temperature of the fourth temperature range.

[0120] In some embodiments, the seventh temperature range can be [103 degrees, +∞ degrees), [104 degrees, +∞ degrees), or [105 degrees, +∞ degrees]. It should be understood that the seventh temperature range can be set according to actual needs, and this disclosure does not specifically limit it.

[0121] In some embodiments, when the heater temperature falls into the seventh temperature range where the temperature is relatively high, controlling the heater 109 to stop operating can effectively prevent the heater 109 from overheating, avoid damage to the internal components of the cleaning equipment 100 due to excessive temperature, and thus extend the service life of the cleaning equipment 100.

[0122] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: after the heater temperature falls into the seventh temperature range, if the heater temperature falls into the eighth temperature range, control the heater 109 to operate, wherein the maximum temperature of the eighth temperature range is less than the minimum temperature of the seventh temperature range.

[0123] In some embodiments, the eighth temperature range can be (-∞ degrees, 101 degrees), (-∞ degrees, 102 degrees), or (-∞ degrees, 103 degrees). It should be understood that the eighth temperature range can be set according to actual needs, and this disclosure does not impose specific limitations on it.

[0124] In some embodiments, if the heater temperature drops from the seventh temperature range back to the eighth temperature range, restarting the heater 109 ensures that the cleaning equipment 100 can stably and continuously perform cleaning tasks in steam mode. Furthermore, by setting a buffer zone between the eighth and seventh temperature ranges (e.g., a buffer zone of 2 degrees between the eighth temperature range [-∞, 102 degrees] and the seventh temperature range [104, +∞)), frequent start-ups and shutdowns of the heater 109 can be prevented, reducing device wear and tear, thereby improving the overall stability and reliability of the cleaning equipment 100 in performing cleaning tasks in steam mode.

[0125] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to control the operating power of the heater 109 to gradually decrease from the first power to the second power.

[0126] In some embodiments, the controller 300 may also be configured to control the operating power of the heater 109 to gradually decrease from the first power to the second power according to a set power amplitude and a set time interval.

[0127] In some embodiments, the first power is gradually reduced to the second power according to a set power amplitude and a set time interval. For example, the operating power of the heater 109 may be gradually reduced to the first power at a rate of 10 watts per second, or the operating power of the heater 109 may be gradually reduced to the first power at a rate of 12 watts per second.

[0128] In some embodiments, by gradually reducing the power of the heater 109, the change in steam volume can be ensured to be smooth, avoiding a sudden disappearance of the steam effect and thus improving the user experience. Furthermore, through a time protection mechanism and a gradual power reduction strategy, the heater 109 can be prevented from operating at high power for extended periods, thereby preventing overheating and dry burning of the heater 109. This effectively prevents inaccurate heater temperature detection caused by malfunction or abnormality of the temperature detection device 117, reducing the risk of malfunction of the cleaning equipment 100 due to misoperation. Therefore, the operational safety, reliability, and service life of the cleaning equipment 100 in steam mode can be improved.

[0129] Referring again to Figure 2, in some embodiments, the cleaning device 100 further includes a liquid detection device 102, configured to detect whether there is flowing liquid in the liquid pipeline of the cleaning device 100; the controller 300 may also be configured to: after controlling the liquid pump 113 to stop supplying liquid to the heater 109 and controlling the heater 109 to run, if the duration for which there is no flowing liquid in the liquid pipeline of the cleaning device 100 meets a sixth duration, then control the heater 109 to stop running; if the duration for which there is flowing liquid in the liquid pipeline meets a seventh duration, then control the heater 109 to run, wherein the sixth duration is less than the seventh duration.

[0130] In some embodiments, the value range of the sixth duration can be 0.5-1.5 seconds; for example, the sixth duration can be 1 second or 1.2 seconds. The value range of the seventh duration can be 1.5-2.5 seconds; for example, the seventh duration can be 2 seconds or 2.2 seconds. It should be understood that the sixth and seventh durations can be set according to actual needs, and this disclosure does not impose specific limitations on them.

[0131] In some embodiments, if there is no continuously flowing liquid in the liquid line of the cleaning device 100 within a sixth time period, an alarm can be issued to remind the user to add liquid to the cleaning device 100 in a timely manner.

[0132] In some embodiments, on the one hand, after controlling the operation of the heater 109, by detecting the liquid in the liquid pipeline of the cleaning equipment 100 and delaying the liquid supply, it is possible to effectively prevent the heater 109 from starting when there is no liquid or insufficient liquid in the liquid pipeline, thus avoiding damage to the cleaning equipment components or safety accidents caused by the dry burning of the heater 109. On the other hand, based on confirming the presence of liquid flow in the liquid pipeline, by delaying for a seventh time, it is possible to ensure that the liquid flows stably and completely to the heater 109 before controlling the heater 109 to restart, thereby avoiding the situation where the heater 109 dry burns due to unstable liquid flow or the liquid in the liquid pipeline not completely flowing to the heater 109. Therefore, this disclosure can improve the operational safety, operational reliability, and service life of the cleaning equipment 100 in steam mode.

[0133] Referring again to Figure 2, in some embodiments, the controller 300 may also be configured to: control the heater 109 to operate if the heater temperature of the cleaning device 100 in standby mode is less than or equal to a second temperature; and control the heater 109 to stop operating if the heater temperature of the cleaning device 100 in standby mode is greater than or equal to a third temperature, wherein the third temperature is greater than the second temperature.

[0134] In some embodiments, the second temperature can be in the range of 40-50 degrees Celsius; for example, the second temperature can be 45 degrees Celsius or 46 degrees Celsius. It should be understood that the second temperature can be set according to actual needs, and this disclosure does not impose any specific limitations on it.

[0135] In some embodiments, the third temperature can be in the range of 45-55 degrees Celsius; for example, the third temperature can be 50 degrees Celsius or 51 degrees Celsius. It should be understood that the third temperature can be set according to actual needs, and this disclosure does not impose any specific limitations on it.

[0136] In some embodiments, when the cleaning equipment 100 is in standby mode, by maintaining the heater temperature between the second and third temperatures, it can achieve faster steam generation when the heater 109 needs to quickly enter the steam mode, thereby improving the overall operating efficiency and reliability of the cleaning equipment 100.

[0137] In some embodiments, the controller 300 may control the cleaning equipment 100 based solely on the control logic described above for the heater liquid pump 107, or it may control the cleaning equipment 100 based solely on the control logic described above for the heater 109.

[0138] In some embodiments, the controller 300 can also control the cleaning equipment 100 based on the control logic for the heater liquid pump 107 and the heater 109 described above. Therefore, the reliability of the cleaning equipment 100 in performing cleaning tasks in steam mode can be further enhanced. In some embodiments, the cleaning equipment 100 can achieve coordinated operation of the heater 109 and the heater liquid pump 107 to ensure the stability and continuity of steam supply. By synchronously adjusting the operating power of the heater 109 and the flow rate of the liquid supplied by the heater liquid pump 107, the amount of steam generated and the delivery rate can be precisely controlled, thereby optimizing the cleaning effect. Furthermore, the combination of dual control logic can maintain the overall stability of the system by adjusting the other component when one component malfunctions, further improving the safety and reliability of the equipment. Overall, the cleaning equipment proposed in this disclosure not only improves cleaning efficiency in steam mode but also extends the service life of the equipment, reduces maintenance costs, and provides users with a more efficient and reliable cleaning solution.

[0139] Next, this disclosure will briefly describe the controller 300 in the cleaning equipment 100 with reference to FIG3.

[0140] Referring to Figure 3, a schematic diagram of the controller in an embodiment of this disclosure is shown.

[0141] As shown in Figure 3, the controller 300 may include at least one memory 304, at least one processor 302, and at least one computer program (computer program instructions) stored in the memory 304 and executable on the processor 302. When the processor 302 executes the computer program, it implements control logic for each device in the cleaning equipment as described above (such as heater liquid pump 107, heater 109, and liquid pump 113 shown in Figure 2).

[0142] In some embodiments, in FIG3, a bus architecture (represented by bus 306) is used. Bus 306 may include any number of interconnected buses and bridges, linking various circuits including at least one processor represented by processor 302 and a memory represented by memory 304. Bus 306 may also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. Bus interface 305 provides an interface between bus 306 and receiver 301 and transmitter 303. Receiver 301 and transmitter 303 may be the same element, i.e., a transceiver, providing a unit for communicating with various other devices over a transmission medium. Processor 302 is responsible for managing bus 306 and general processing, while memory 304 may be used to store data used by processor 302 during operation.

[0143] Figure 6 shows a schematic diagram of a cleaning system according to some embodiments of the present disclosure. As shown in Figure 6, based on the same inventive concept, an embodiment of the present disclosure also provides a cleaning system 1000. The cleaning system 1000 includes a base station 1010 and a cleaning device 100 as described above. The base station 1010 is used to place the cleaning device 100 and to charge the cleaning device 100 and replenish it with liquid, such as clean water.

[0144] Based on the same inventive concept, embodiments of this disclosure also provide a cleaning equipment control method, wherein the cleaning equipment includes a heater and a heater liquid pump. Referring to FIG4, a flowchart of a cleaning equipment control method according to some embodiments of this disclosure is shown. This cleaning equipment control method can be executed by a device with computational processing capabilities to implement control logic for the heater liquid pump in the cleaning equipment in steam mode. It should be noted that for details not disclosed in the embodiments of the method of this disclosure, please refer to the embodiments of the cleaning equipment described above.

[0188] It should be noted that the above-mentioned control methods for cleaning equipment shown in Figure 4 and Figure 5 can be applied individually or in combination to control scenarios for cleaning equipment. This disclosure does not impose any further limitations on this.

[0189] However, it should be understood that in the control scenario of cleaning equipment, combining the control methods for the cleaning equipment shown in Figure 4 and Figure 5 can further enhance the reliability of the cleaning equipment in performing cleaning tasks in steam mode. In some embodiments, the cleaning equipment can achieve coordinated operation of the heater and the heater liquid pump to ensure the stability and continuity of steam supply. By synchronously adjusting the operating power of the heater and the flow rate of the liquid supplied by the heater liquid pump, the amount of steam generated and the delivery rate can be precisely controlled, thereby optimizing the cleaning effect. In addition, by combining dual control logic, the overall stability of the system can be maintained by adjusting the other component when one component malfunctions, further improving the safety and reliability of the equipment. Overall, the cleaning equipment proposed in this disclosure not only improves the cleaning efficiency in steam mode but also extends the service life of the equipment, reduces maintenance costs, and provides users with a more efficient and reliable cleaning solution.

[0190] Based on the same inventive concept, this disclosure provides a computer program product including computer instructions stored in a computer-readable storage medium and adapted to be read and executed by a processor to cause a computer device having the processor to perform the operations performed by the cleaning equipment control method as described above.

[0191] Based on the same inventive concept, embodiments of this disclosure provide a computer-readable storage medium storing at least one computer program instruction, which is loaded and executed by a processor to implement the operations performed by the cleaning equipment control method as described above.

[0192] Based on the technical solution proposed in this disclosure, the cleaning equipment can stably generate steam by dynamically adjusting the flow rate of liquid supplied to the heater by the heater liquid pump in real time, thereby ensuring the reliability of the cleaning equipment in steam mode. When the heater temperature falls into the first temperature range, the liquid flow rate of the heater liquid pump is automatically controlled at the first flow rate to ensure the normal operation of the steam mode. Once the temperature exceeds the first temperature range, i.e., the temperature rises and falls into the second temperature range, the heater liquid pump is controlled to supply liquid to the heater at a second flow rate greater than the first flow rate to balance the heat generated by the heater, thereby effectively reducing the heater temperature to the first temperature range.

[0193] In addition, the cleaning equipment can monitor the heater temperature in real time and dynamically adjust the heater's operating power according to the temperature range, ensuring that the heater temperature remains within a safe and efficient operating range. In some embodiments, if the heater temperature falls into a lower third temperature range, controlling the heater to operate at a higher first power allows the liquid in the heater to absorb more heat, increasing the rate and magnitude of temperature change. This facilitates rapid steam generation, improving the response speed of the cleaning equipment in steam mode and ensuring the reliability of cleaning tasks, thus enhancing the user experience. If the heater temperature falls into a higher fourth temperature range, controlling the heater to operate at a lower second power ensures a stable and sufficient output of steam, preventing excessive evaporation of the liquid due to excessive heat absorption at high temperatures and reducing the risk of dry burning due to rapid evaporation. This improves the operational safety, reliability, and lifespan of the cleaning equipment in steam mode.

[0194] The cleaning equipment disclosed herein, through an adaptive flow regulation mechanism and / or power regulation mechanism, can maintain a stable heater temperature, preventing overheating that could lead to equipment malfunctions or safety hazards. Stable heater temperature enhances the uniformity of steam production, thereby improving the cleaning effect on the floor in steam mode and increasing the efficiency and quality of the cleaning task. Furthermore, the aforementioned flow regulation and / or power regulation mechanisms also contribute to energy conservation, extend the service life of components in the cleaning equipment, and reduce maintenance costs, thus improving the overall reliability and economy of the cleaning equipment.

[0195] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored as at least one instruction or code on or transmitted via a computer-readable medium.

Furthermore, the functional units may be integrated into a single processing unit, or each unit may exist physically separately, or two or more units may be integrated into a single unit.
