[0035] According to a third aspect of an embodiment of the present application, a computer-readable storage medium is provided, in which at least one computer program instruction is stored.

[0036] According to a fourth aspect of the embodiments of the present application, a cleaning system is provided, the cleaning system comprising a base station and the cleaning device described in any one of the embodiments of the first aspect above.

[0037] Based on the technical solution proposed in this application, the cleaning equipment can stably generate steam in the cleaning equipment by monitoring the heater temperature in real time and dynamically adjusting the flow rate of the heater liquid pump to supply liquid to the heater, thereby ensuring the reliability of the cleaning equipment in performing cleaning tasks in the steam mode. Specifically, when the heater temperature falls into the first temperature range, the liquid flow rate of the heater liquid pump is automatically controlled to the first flow rate to ensure the normal operation of the steam mode. Once the temperature exceeds the first temperature range, that is, 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.

[0038] In addition, the cleaning equipment can also monitor the temperature of the heater in real time and dynamically adjust the operating power of the heater according to the temperature range to ensure that the temperature of the heater is within a safe and efficient working range. Specifically, if the temperature of the heater falls into the third temperature range with a lower temperature, by controlling the heater to operate at a higher first power, it is beneficial for the liquid in the heater to absorb more heat, increase the rate of change and amplitude of the liquid temperature, and then facilitate the liquid to quickly produce steam in the heater, play a role in quickly producing steam, improve the response speed of the cleaning equipment in steam mode, ensure the reliability of the cleaning equipment in performing cleaning tasks in steam mode, and thus improve the user experience. If the temperature of the heater falls into the fourth temperature range with a higher temperature, by controlling the heater to operate at a lower second power, the heater can stably produce enough steam while avoiding the situation where the liquid in the heater absorbs too much heat under high temperature and causes excessive evaporation. At the same time, it can also reduce the risk of dry burning of the liquid in the heater due to excessive evaporation, thereby improving the operational safety, operational reliability and service life of the cleaning equipment in steam mode.

[0039] In general, the cleaning equipment proposed in this application can maintain the stability of the heater temperature through an adaptive flow regulation mechanism and / or power regulation mechanism to prevent the heater from overheating and causing equipment failure or safety hazards. At the same time, the stability of the heater temperature enhances the uniformity of steam output, thereby improving the cleaning effect of the cleaning equipment on the ground in steam mode and improving the efficiency and quality of the cleaning equipment in performing cleaning tasks. In addition, the above-mentioned flow regulation mechanism and / or power regulation mechanism also helps to save energy, extend the service life of parts in the cleaning equipment, and reduce maintenance costs, thereby improving the reliability and economy of the cleaning equipment as a whole.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0049] The block diagrams shown in the accompanying drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, or in at least one hardware module or integrated circuit, or in different networks and / or processor devices and / or microcontroller devices. It should also be noted that in the accompanying drawings, in order to ensure the simplicity of the drawings, some devices in the drawings that do not affect the explanation of the technical solution of the present application are adaptively omitted.

[0050] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0051] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0052] In order to make those skilled in the art better understand the present application, firstly, Figure 1 The cleaning equipment and system architecture involved in this application are briefly described.

[0053] See also Figure 1 , shows a system architecture diagram of the cleaning device in an embodiment of the present application.

[0054] like Figure 1, shows a system architecture of a cleaning device in an embodiment, in which the system architecture 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 (such as a boiler), a filter 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 a cleaning component 116 (such as a cleaning roller brush, a mop).

[0055] Among them, the liquid tank 101 is used to store liquid, and the liquid can be clean water or other liquids that can clean the ground or cleaning parts, and this application does not make specific restrictions on this. The liquid detection device 102 (for example, a flow meter, a liquid level meter, etc.) can be used to detect the liquid flow in the liquid pipeline, and can be used to determine whether the liquid in the liquid pipeline is sufficient. The heater liquid pump 107 is used to pump a set flow of liquid into the heater 109, so that the heater 109 heats the liquid to generate steam, and flows to the steam nozzle 112 through the first reversing valve 111, and finally sprays the steam onto the ground. The liquid pump 113 can pump a larger set flow 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 with a higher temperature, and the generated hot liquid then flows to the cleaning part 116 through the first reversing valve 111, so as to clean the ground or clean the cleaning parts with hot liquid. The liquid pump 113 can pump out a relatively low temperature liquid (which can be a liquid at room temperature) directly to the cleaning element 116 through the second reversing valve 114 to clean the floor or wash the cleaning element.

[0056] 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 device. In the cleaning device of this embodiment, the liquid flow path may include flow path A, flow path B, and flow path C, which are used for the cleaning device to perform cleaning tasks in cold liquid mode, hot liquid mode, and steam mode, respectively. In addition, the cleaning device also includes a flow path D, in which the detergent pump 105 pumps the detergent in the detergent tank 104 into the second three-way valve 106 to deliver the detergent to the entire liquid pipeline.

[0057] Specifically, in the cold liquid mode, the second reversing valve 114 is in a closed state, and the liquid flows 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 member 116 in sequence. Since the liquid is not heated by the heater 109, the liquid flowing to the cleaning member 116 is in a low-temperature liquid state (such as a room-temperature liquid state).

[0058] In the hot liquid mode, the first reversing valve 111 and the second reversing valve 114 are both in the open state, and the liquid flows 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 110, the first reversing valve 111, the third three-way valve 115, and the cleaning element 116 in sequence. Since the liquid is heated by the heater 109, the liquid flowing to the cleaning element 116 is in a high-temperature liquid state, which can enhance the cleaning effect on the floor or the cleaning element.

[0059] In the steam mode, the first reversing valve 111 is in a closed state, and the liquid flows 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 110, the first reversing valve 111, and the steam port 112 in sequence. Since the liquid passes through the heater liquid pump 107 and flows through the heater 109 for heating, the liquid flowing to the steam port 112 is in a high-temperature gaseous state, which can enhance the cleaning effect on the floor.

[0060] In practical applications, when the cleaning device cleans the floor, the liquid pump provides liquid to the cleaning member, which can wet the cleaning member, thereby facilitating the cleaning of stains on the floor. Furthermore, when the cleaning device with a steam mode cleans the floor, by spraying steam onto the floor, on the one hand, it can soften the solid stains on the floor and facilitate the cleaning of the solid stains, and on the other hand, it can kill the microorganisms on the floor at high temperature. In this way, the cleaning effect of the cleaning device on the floor can be greatly improved. However, how to stably generate steam in the cleaning device to ensure the reliability of the cleaning device in performing cleaning tasks in the steam mode is crucial. In this case, the present application proposes some embodiments of cleaning devices and control methods thereof to ensure the reliability of the cleaning device in performing cleaning tasks in the steam mode.

[0061] Next, the implementation details of the technical solution of the embodiment of the present application will be elaborated in detail.

[0062] Before the description, it should be noted that, in order to enable those skilled in the art to better understand the present application, the present application will list some embodiments including control parameters. In these embodiments, the specific values ​​of the control parameters are given with reference to the assumption that the liquid is clean water. For the sake of brevity of the specification, the present application will not specifically explain this in the subsequent description. In addition, the specific values ​​of the control parameters in the embodiments are merely exemplary. In actual applications, the control parameters in the embodiments may also be other values ​​according to actual conditions.

[0063] Reference Figure 2 , showing a schematic structural diagram of the cleaning device in an embodiment of the present application.

[0064] Reference Figure 2 The cleaning device 100 proposed in the present application may include a heater 109 , a heater liquid pump 107 , a temperature detection device 117 , and a controller 300 .

[0065] Among them, the heater 109 can be configured to: heat the liquid to generate steam; the heater liquid pump 107 is connected to the heater 109, and the heater liquid pump 107 can be configured to: supply liquid to the heater 109; the temperature detection device 117 is provided on the heater 109, and the temperature detection device 117 can be configured to: collect the heater temperature; the controller 300 is communicatively connected with the heater 109, the heater liquid pump 107, and the temperature detection device 117.

[0066] Continue to refer to Figure 2 In the present application, the controller 300 can be configured as follows: in the steam mode, obtaining the heater temperature collected by the temperature detection device 117; if the heater temperature falls within the first temperature range, controlling the heater liquid pump 107 to supply liquid to the heater 109 at a first flow rate; if the heater temperature falls within the second temperature range, controlling 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.

[0067] In the present application, the temperature detection device 117 can be a negative temperature coefficient thermistor (NTC), a thermocouple (Thermocouple), an infrared temperature sensor (ITS), a semiconductor temperature sensor (STS), or a bimetallic temperature sensor (BTS), and the present application does not make any specific limitations on this.

[0068] In the present application, the first temperature interval may be [97 degrees, 99 degrees), or [98 degrees, 98 degrees), or [99 degrees, 100 degrees). It should be understood that the first temperature interval may be set according to actual needs, and the present application does not make any specific limitation on this.

[0069] In the present application, the second temperature range may be [98 degrees, +∞ degrees), [99 degrees, +∞ degrees), or [100 degrees, +∞ degrees). It should be understood that the second temperature range may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0070] In the present application, the value range of the first flow rate can be 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 the present application does not make specific limitations on this.

[0071] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature falls into the second temperature range, a set flow amplitude is increased on the basis of the first flow to obtain the second flow, and the set flow amplitude is positively correlated with the excess value of the heater temperature over the minimum temperature in the second temperature range.

[0072] In the present application, after the heater temperature falls into the second temperature interval, relative to the minimum temperature in the second temperature interval, the set flow amplitude can be adjusted up by a certain amplitude for each degree the heater temperature exceeds. For example, when the second temperature interval is [98 degrees, +∞ degrees), the first flow is 1.8 ml / min, and when the heater temperature exceeds 98 degrees by 1 degree (that is, the heater temperature is 99 degrees), the set flow amplitude is 0.4 ml / min, that is, the second flow is 2.2 ml / min. When the heater temperature exceeds 98 degrees by 2 degrees (that is, the heater temperature is 100 degrees), the set flow amplitude is 0.8 ml / min, that is, the second flow is 2.6 ml / min. When the heater temperature exceeds 98 degrees by 3 degrees (that is, the heater temperature is 101 degrees), the set flow amplitude is 1.2 ml / min, that is, the second flow is 3 ml / min. When the heater temperature exceeds 98 degrees by 4 degrees (i.e., the heater temperature is 102 degrees), the set flow rate amplitude is 2.7 ml / min, i.e., the second flow rate is 4.5 ml / min. When the heater temperature exceeds 98 degrees by 5 degrees or more (e.g., the heater temperature is 103 degrees), the set flow rate amplitude is 3.2 ml / min, i.e., the second flow rate is 5 ml / min.

[0073] In the present application, it can also be that after the heater temperature falls into the second temperature interval, relative to the minimum temperature in the second temperature interval, the set flow amplitude can be increased by 0.2 ml / min for every 1 degree that the heater temperature exceeds. For example, when the second temperature interval is [99 degrees, +∞ degrees), when the corresponding first flow is 2 ml / min, if the heater temperature is 100 degrees, the set flow amplitude is 0.2 ml / min, that is, the second flow is 2.2 ml / min, if the heater temperature is 101 degrees, the set flow amplitude is 0.4 ml / min, that is, the second flow is 2.4 ml / min. It should be understood that under the logic that the set flow amplitude is positively correlated with the excess value of the heater temperature exceeding the minimum temperature in the second temperature interval, the set flow amplitude added on the basis of the first flow can be set according to actual needs, and this application does not make specific restrictions on this.

[0074] In the present application, it should be noted that if the temperature of the heater returns from the second temperature range to the first temperature range, the heater liquid pump 107 in the cleaning device 100 can continue to be controlled to supply liquid to the heater 109 at the first flow rate.

[0075] Based on the technical solution proposed in this application, the cleaning equipment can stably generate steam in the cleaning equipment by monitoring the temperature of the heater in real time and dynamically adjusting the flow rate of the heater liquid pump to supply liquid to the heater, so as to ensure the reliability of the cleaning equipment in performing cleaning tasks in steam mode. Specifically, when the temperature of the heater falls into the first temperature interval, 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 interval, that is, the temperature rises and falls into the second temperature interval, the heater liquid pump 107 is controlled to supply liquid to the heater 109 according to the second flow rate greater than the first flow rate to balance the heat generated by the heater 109, so that the heater temperature can be effectively reduced to the first temperature interval. In this way, through this adaptive flow regulation mechanism, the temperature of the heater can be kept stable, and the overheating of the heater can be prevented from causing equipment failure or safety hazards. At the same time, the stability of the heater temperature enhances the uniformity of steam output, so as to improve the cleaning effect of the cleaning equipment on the ground in steam mode, and ensure the efficiency and quality of the cleaning equipment in performing cleaning tasks. In addition, the flow regulation mechanism also helps to save energy, extend the service life of parts in the cleaning equipment, and reduce maintenance costs, thereby improving the reliability and economy of the cleaning equipment as a whole.

[0076] Continue to refer to Figure 2In the present application, the controller 300 can also be configured as follows: if the heater temperature falls into the fifth temperature interval, the heater liquid pump 107 is controlled to intermittently supply liquid to the heater 109, and the fifth temperature interval and the first temperature interval are adjacent temperature intervals, and the maximum temperature of the fifth temperature interval is less than the minimum temperature of the first temperature interval.

[0077] In the present application, the fifth temperature interval may include a plurality of temperature sub-intervals connected in sequence.

[0078] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature falls into a first temperature sub-interval, the heater liquid pump is controlled to supply liquid to the heater at a third flow rate, and the third flow rate is less than the first flow rate; if the heater temperature falls into a second temperature sub-interval, the heater liquid pump is controlled to stop supplying liquid to the heater, and the first temperature sub-interval and the second temperature sub-interval are any two adjacent temperature sub-intervals among the multiple temperature sub-intervals.

[0079] In the present application, the interval length of the temperature sub-interval may be greater than the first length threshold and less than the second length threshold. For example, the first length threshold may be 5 degrees, and the second length threshold may be 15 degrees. It should be understood that the first length threshold and the second length threshold may be set according to actual needs, and the present application does not specifically limit this.

[0080] In the present application, the interval lengths of various temperature sub-intervals may be the same or different.

[0081] In order to enable those skilled in the art to better understand the present application, this embodiment will be described below with a specific example.

[0082] In this specific example, the fifth temperature interval may be [30 degrees, 98 degrees), and the third flow rate may be 1.4 ml / min. Based on this, the heater liquid pump 107 may 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.

[0083] Temperature sub-range Liquid supply flow parameter values 30-40 degrees 1.4ml / min 40-50 degrees 0ml / min 50-60 degrees 1.4ml / min 60-70 degrees 0ml / min 70-80 degrees 1.4ml / min 80-90 degrees 0ml / min 90-97 degrees 1.4ml / min

[0084] Table 1

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

[0086] First, by setting reasonable temperature sub-intervals and intermittently supplying liquid, when the heater temperature is in the lower fifth temperature interval, the heater liquid pump 107 is controlled to intermittently supply liquid to the heater 109 at a third flow rate with a smaller flow rate, which can accelerate the speed of steam generation on the one hand, and effectively prevent the liquid in the heater 109 from being quickly evaporated during the period of stopping the liquid supply, causing the heater 109 to dry out. The risk of failure of the heater 109 caused by overheating is reduced, the service life of the heater 109 and related components is extended, and the maintenance and replacement costs of the cleaning equipment are reduced.

[0087] Secondly, setting the interval length of the temperature sub-interval within a reasonable range can avoid the situation where the temperature detection device 117 collects the heater temperature inaccurately due to the temperature sub-interval length being too short, and can also avoid the situation where the heater 109 is dry-burned due to the rapid evaporation of liquid and insufficient supply during the period when the liquid supply is stopped due to the temperature sub-interval length being too long, thereby ensuring the safety and reliability of the cleaning equipment in performing cleaning tasks in steam mode.

[0088] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature falls into a sixth temperature interval, the heater liquid pump 107 is controlled to stop supplying liquid to the heater 109, and the sixth temperature interval and the fifth temperature interval are adjacent temperature intervals, and the maximum temperature of the sixth temperature interval is less than the minimum temperature of the fifth temperature interval.

[0089] In the present application, the sixth temperature interval may be (-∞ degrees, 30 degrees), and if the heater temperature falls into the sixth temperature interval, the heater 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 temperature rise effect.

[0090] Continue to refer to Figure 2 In the present application, the cleaning device 100 may further include a liquid pump 113, which is connected to the heater 109 and may be configured to supply liquid to the heater 109, wherein a flow rate of liquid supplied by the liquid pump 113 to the heater 109 is greater than a flow rate of liquid supplied by the heater liquid pump 107 to the heater 109.

[0091] Furthermore, the controller 300 can also be configured to: in response to the cleaning device 100 being triggered to enter the steam mode, control the liquid pump 113 to supply liquid to the heater 109; after the liquid pump 113 supplies liquid to the heater 109 for a first period of time, 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 may control the cleaning device 100 to enter the steam mode after receiving a control instruction to enter the steam mode triggered by the user. When the cleaning device 100 enters the steam mode, the controller 300 may control the cleaning device 100 to enter the steam mode. Figure 1 The second reversing valve 114 is shown to be in an open state, after which the controller 300 can control the liquid pump 113 in the cleaning device 100 to supply liquid to the heater 109 .

[0093] In the present application, the value range of the first duration may be 3-8 seconds, for example, the first duration may be 5 seconds or 6 seconds. It should be understood that the first duration may be set according to actual needs, and the present application does not make any specific limitation on this.

[0094] In the present application, 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 when the cleaning device 100 enters the steam mode, then the initial temperature of the heater 109 may be at a higher state, which may quickly trigger the self-protection mechanism of the heater 109 (that is, the heater 109 operates at a lower operating power (for example, 145 watts)), resulting in less heat generated by the heater 109, and the liquid in the heater 109 cannot produce steam quickly due to the 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, since the operating power of the liquid pump 113 is relatively large (for example, 10V, 15V), a large flow of liquid can be supplied to the heater 109, so that the temperature of the heater can be cooled down to a certain temperature, which is not easy to trigger the self-protection mechanism of the heater 109, so that the heater 109 can be allowed to run for a longer time at a higher operating power (for example, 285 watts), which is beneficial for the liquid in the heater 109 to absorb more heat in a short time, increase the rate of change and amplitude of the liquid temperature, and thus facilitate the liquid in the heater 109 to quickly produce steam, thereby achieving the effect of quickly producing steam. In this way, the response speed of the cleaning device 100 in the steam mode can be improved, and the reliability of the cleaning device 100 in performing cleaning tasks in the steam mode can be ensured, thereby improving the user experience. Continue to refer to Figure 2 In the present application, the cleaning device 100 may further include a cleaning member 116, the liquid pump 113 is connected to the cleaning member 116, and the cleaning member 116 may be configured to: clean the floor.

[0096] Further, 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 operate, if the heater 109 operates for a second time period and the temperature of the heater is greater than or equal to the first temperature, control as follows: Figure 1 The second reversing valve 114 is shown in a closed state to control the liquid pump 113 to directly supply liquid to the cleaning member 116; if the heater temperature is lower than the first temperature, the cleaning device 100 is controlled to issue a prompt message indicating that steam is being prepared.

[0097] In the present application, the second duration may be set within a range of 15-25 seconds, for example, the second duration may be 20 seconds or 22 seconds. It should be understood that the second duration may be set according to actual needs, and the present application does not specifically limit this.

[0098] In the present application, the value range of the first temperature may be 85-95 degrees, for example, the first temperature may be 90 degrees or 92 degrees. It should be understood that the first temperature may be set according to actual needs, and the present application does not make any specific limitation on this.

[0099] In the present application, after controlling the liquid pump 113 to stop supplying liquid to the heater 109, if the duration of the operation of the heater 109 satisfies 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 capacity and the produced steam can meet the cleaning requirements. At this time, the liquid pump 113 is controlled to directly supply liquid to the cleaning part 116 of the cleaning device 100, so that the cleaning device 100 can perform the cleaning task in the steam mode and the cold liquid mode at the same time, thereby enhancing the cleaning ability of the cleaning device 100, ensuring the reliability of the cleaning device 100 in performing the cleaning task, and improving the user experience.

[0100] In the present application, after controlling the liquid pump 113 to stop supplying liquid to the heater 109, if the heater temperature is lower than the first temperature, it means that the heater 109 is still unable to generate steam in a very short time. In this case, by controlling the cleaning device 100 to issue a prompt message indicating that steam is being prepared, the user can be reminded to wait, thereby preventing the user from mistakenly believing that the cleaning device 100 has a fault, thereby improving the user experience.

[0101] Continue to refer to Figure 2In the present application, the cleaning device 100 also includes: a liquid detection device 102, and the liquid detection device 102 is configured to: detect whether there is flowing liquid in the liquid pipeline of the cleaning device 100; the controller 300 can also be configured to: if the duration of the flowing liquid in the liquid pipeline of the cleaning device 100 meets the third time length, then control the heater liquid pump 107 to supply liquid to the heater 109; if the duration of the absence of flowing liquid in the liquid pipeline meets the fourth time length, then control the heater liquid pump 107 to stop supplying liquid to the heater 109.

[0102] Further, in the present application, the fourth duration may be shorter than the third duration.

[0103] In the present application, a liquid detection device 102 may be provided in the liquid pipeline of the cleaning device 100 to detect whether there is flowing liquid in the liquid pipeline of the cleaning device 100. In some embodiments, the liquid detection device 102 may be a flow meter or a liquid level meter, which is not specifically limited in the present application.

[0104] In the present application, the value interval of the third duration may be 1.5-2.5 seconds, for example, the third duration may be 2 seconds or 2.2 seconds. The value interval of the fourth duration may be 0.5-1.5 seconds, for example, the fourth duration may be 1 second or 1.2 seconds. It should be understood that the third duration and the fourth duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0105] In the present application, if there is no continuous flowing liquid in the liquid pipeline of the cleaning device 100 within the fourth time period, an alarm may be issued to remind the user to add liquid to the cleaning device 100 in time.

[0106] In the present application, on the one hand, after the cleaning device 100 enters the steam mode, by detecting the liquid in the liquid pipeline of the cleaning device 100 and delaying the control of the liquid supply, it is possible to effectively prevent the heater liquid pump 107 from being started when there is no liquid or insufficient liquid in the liquid pipeline, which triggers the start of the heater 109 and avoids damage to the components or safety accidents in the cleaning device 100 caused by the dry burning of the heater 109. On the other hand, on the basis of confirming that there is liquid flow in the liquid pipeline, by delaying the third time length and then controlling the heater liquid pump 107 to supply liquid to the heater 109, it can be ensured that the liquid flows stably to the heater 109, thereby avoiding the situation where the heater 109 is dry burned due to unstable liquid flow or the liquid in the liquid pipeline does not flow completely to the heater 109. Therefore, the present application can improve the operational safety, operational reliability and service life of the cleaning device 100 in the steam mode.

[0107] Continue to refer to Figure 2 In the present application, 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 the present application, after the cleaning device 100 exits the steam mode, the time interval for controlling the heater liquid pump 107 to supply liquid to the heater 109 can be 1-10 seconds, for example, specifically 5 seconds or 5.5 seconds. It should be understood that the time length can be set according to actual needs, and the present application does not make specific limitations on this.

[0109] In the present application, after the cleaning device 100 exits the cleaning task in steam mode, 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 quickly cooled down to avoid damage to components in the cleaning device 100 due to excessive temperature of the heater 109, thereby increasing the service life of the cleaning device 100.

[0110] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature falls within the third temperature range, the heater 109 is controlled to operate at the first power; if the heater temperature falls within the fourth temperature range, the heater 109 is controlled to operate at the second power, 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 the present application, the third temperature interval may be (-∞ degrees, 96 degrees), (-∞ degrees, 97 degrees), or (-∞ degrees, 98 degrees). It should be understood that the third temperature interval may be set according to actual needs, and the present application does not make any specific limitation on this.

[0112] In the present application, the fourth temperature interval may be [96 degrees, 104 degrees), or [97 degrees, 104 degrees), or [98 degrees, 104 degrees). It should be understood that the fourth temperature interval may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0113] In the present application, the value range of the first power may be 275-300 W, for example, the first power may be 285 W or 280 W. It should be understood that the first power may be set according to actual needs, and the present application does not specifically limit this.

[0114] In the present application, the second power may be in a value range of 135-170 W, for example, the second power may be 145 W or 140 W. It should be understood that the second power may be set according to actual needs, and the present application does not specifically limit this.

[0115] In the present application, by real-time monitoring of the heater temperature and dynamically adjusting the operating power of the heater according to the temperature range, it is possible to ensure that the heater temperature is within a safe and efficient working range. Specifically, if the heater temperature falls into the third temperature range with a lower temperature, by controlling the heater to operate at a higher first power, it is beneficial for the liquid in the heater to absorb more heat, increase the rate of change and amplitude of the liquid temperature, and thus facilitate the liquid to quickly produce steam in the heater, play a role in quickly producing steam, improve the response speed of the cleaning equipment in the steam mode, ensure the reliability of the cleaning equipment in performing cleaning tasks in the steam mode, and thus improve the user experience. If the heater temperature falls into the fourth temperature range with a higher temperature, by controlling the heater to operate at a lower second power, it is possible to stably produce sufficient steam in the heater while avoiding the situation where the liquid in the heater absorbs too much heat under high temperature and causes excessive evaporation, and at the same time, it can also reduce the risk of dry burning of the liquid in the heater due to excessive evaporation, thereby improving the operational safety, operational reliability and service life of the cleaning equipment in the steam mode.

[0116] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured to: if the duration of the operation of the heater 109 at the first power is greater than or equal to the fifth duration, control the heater 109 to operate at the second power.

[0117] In the present application, the value range of the fifth duration may be 55-65 seconds, for example, the fifth duration may be 60 seconds or 58 seconds. It should be understood that the fifth duration may be set according to actual needs, and the present application does not make any specific limitation on this.

[0118] In the present application, if the duration of the heater temperature falling into the third temperature interval is too long, one reason may be that the amount of liquid in the heater 109 is large. Even if the heater temperature does not fall into the fourth temperature interval, since the heater 109 heats the liquid therein at a higher operating power for a longer time, the liquid in the heater 109 absorbs more heat, and sufficient steam can be generated in the heater 109. By reducing the first power to the second power, the benefit is that it can effectively save energy, reduce the power consumption of the heater 109, and reduce the operating pressure and heat load of the heater 109. In this way, it not only helps to extend the service life of the heater 109, but also improves the overall efficiency of the heater 109. Another reason may be that the temperature detection device 117 fails or is abnormal. In this case, if the duration of the heater 109 running at the first power is greater than or equal to the fifth duration, the heater 109 is controlled to run at the second power, which can effectively prevent the inaccurate heater temperature detection caused by the failure or abnormality of the temperature detection device 117, resulting in the actual temperature of the heater 109 being too high and damaging the device.

[0119] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature falls into the seventh temperature interval, the heater 109 is controlled to stop running, the seventh temperature interval and the fourth temperature interval are adjacent temperature intervals, and the minimum temperature of the seventh temperature interval is greater than the maximum temperature of the fourth temperature interval.

[0120] In the present application, the seventh temperature interval may be [103 degrees, +∞ degrees), [104 degrees, +∞ degrees), or [105 degrees, +∞ degrees). It should be understood that the seventh temperature interval may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0121] In the present application, when the heater temperature falls into the seventh temperature range with higher temperature, by controlling the heater 109 to stop running, the heater 109 can be effectively prevented from overheating, avoiding damage to the internal components of the cleaning device 100 due to excessive temperature, thereby extending the service life of the cleaning device 100.

[0122] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured as follows: after the heater temperature falls into the seventh temperature interval, if the heater temperature falls into the eighth temperature interval, the heater 109 is controlled to operate, and the maximum temperature of the eighth temperature interval is less than the minimum temperature of the seventh temperature interval.

[0123] In the present application, the eighth temperature interval can be (-∞ degrees, 101 degrees], (-∞ degrees, 102 degrees], or (-∞ degrees, 103 degrees]. It should be understood that the eighth temperature interval can be set according to actual needs, and the present application does not make specific limitations on this.

[0124] In the present application, if the heater temperature drops from the seventh temperature interval to the eighth temperature interval, the cleaning device 100 can be ensured to stably and continuously perform cleaning tasks in the steam mode by restarting the heater 109. In addition, by setting a buffer zone between the eighth temperature interval and the seventh temperature interval (for example, the buffer zone between the eighth temperature interval (-∞ degrees, 102 degrees) and the seventh temperature interval [104 degrees, +∞ degrees) is 2 degrees), the heater 109 can be prevented from being frequently started and stopped, and the device loss can be reduced, thereby improving the overall stability and reliability of the cleaning device 100 in performing cleaning tasks in the steam mode.

[0125] Continue to refer to Figure 2 In the present application, 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] Furthermore, 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 the present application, the first power is gradually reduced to the second power according to the set power amplitude and the 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 the present application, by slowly reducing the power of the heater 109, it is possible to ensure a smooth change in the amount of steam, avoid the sudden disappearance of the steam effect, and thus improve the user experience. In addition, through the time protection mechanism and the progressive power reduction strategy, it is possible to avoid the heater 109 from working for a long time at high power, thereby preventing the heater 109 from drying out due to overheating, and effectively preventing inaccurate heater temperature detection caused by failure or abnormality of the temperature detection device 117, thereby reducing the risk of malfunction of the cleaning device 100 due to misoperation. In this way, the operational safety, operational reliability and service life of the cleaning device 100 in steam mode can be improved.

[0129] Continue to refer to Figure 2In the present application, the cleaning device 100 further includes: a liquid detection device 102, and the liquid detection device 102 is configured to: detect whether there is flowing liquid in the liquid pipeline of the cleaning device 100; the controller 300 can also be configured to: after controlling the liquid pump 113 to stop supplying liquid to the heater 109 and controlling the heater 109 to operate, if the duration of the absence of flowing liquid in the liquid pipeline of the cleaning device 100 satisfies a sixth time length, then control the heater 109 to stop operating; if the duration of the presence of flowing liquid in the liquid pipeline satisfies a seventh time length, then control the heater 109 to operate, and the sixth time length is less than the seventh time length.

[0130] In the present application, the value interval of the sixth duration may be 0.5-1.5 seconds, for example, the sixth duration may be 1 second or 1.2 seconds. The value interval of the seventh duration may be 1.5-2.5 seconds, for example, the seventh duration may be 2 seconds or 2.2 seconds. It should be understood that the sixth duration and the seventh duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0131] In the present application, if there is no continuous flowing liquid in the liquid pipeline of the cleaning device 100 within the sixth time period, an alarm may be issued to remind the user to add liquid to the cleaning device 100 in time.

[0132] In the present application, on the one hand, after controlling the operation of the heater 109, by detecting the liquid in the liquid pipeline of the cleaning device 100 and delaying the control of the liquid supply, it is possible to effectively prevent the heater 109 from being started when there is no liquid or insufficient liquid in the liquid pipeline, thereby avoiding damage to the cleaning equipment components or safety accidents caused by the dry burning of the heater 109. On the other hand, on the basis of confirming that there is liquid flow in the liquid pipeline, by delaying the seventh time period, it is possible to ensure that the liquid flows stably and completely flows to the heater 109 and then control the heater 109 to restart operation, thereby avoiding the situation where the heater 109 is dry burned due to unstable liquid flow or the liquid in the liquid pipeline not completely flowing to the heater 109. Therefore, the present application can improve the operational safety, operational reliability and service life of the cleaning equipment 100 in steam mode.

[0133] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature of the cleaning device 100 in the standby state is less than or equal to the second temperature, the heater 109 is controlled to operate; if the heater temperature of the cleaning device 100 in the standby state is greater than or equal to the third temperature, the heater 109 is controlled to stop operating, and the third temperature is greater than the second temperature.

[0134] In the present application, the second temperature may be in the range of 40-50 degrees, for example, the second temperature may be 45 degrees or 46 degrees. It should be understood that the second temperature may be set according to actual needs, and the present application does not specifically limit this.

[0135] In the present application, the value range of the third temperature may be 45-55 degrees, for example, the third temperature may be 50 degrees or 51 degrees. It should be understood that the third temperature may be set according to actual needs, and the present application does not make any specific limitation on this.

[0136] In the present application, when the cleaning device 100 is in standby mode, by maintaining the heater temperature between the second temperature and the third temperature, faster steam generation can be achieved when the heater 109 needs to quickly enter the steam mode, thereby improving the overall operating efficiency and reliability of the cleaning device 100.

[0137] In the present application, the controller 300 may control the cleaning device 100 based only on the control logic for the heater liquid pump 107 , or may control the cleaning device 100 based only on the control logic for the heater 109 .

[0138] In the present application, the controller 300 can also control the cleaning device 100 based on the above-mentioned control logic for the heater liquid pump 107 and the heater 109 at the same time. In this way, the reliability of the cleaning device 100 in performing cleaning tasks in the steam mode can be further enhanced. Specifically, the cleaning device 100 can realize the coordinated work of the heater 109 and the heater liquid pump 107 to ensure the stability and continuity of the steam supply. By synchronously adjusting the operating power of the heater 109 and the flow rate of the heater liquid pump 107 supplying liquid, the amount of steam generated and the delivery rate can be accurately controlled, thereby optimizing the cleaning effect. In addition, in combination with the dual control logic, when a component is abnormal, the overall stability of the system can be maintained by adjusting another component, further improving the safety and reliability of the equipment. Overall, the cleaning device proposed in this application not only improves the cleaning efficiency in the 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 application will combine Figure 3 , a brief description is given of the controller 300 in the cleaning device 100.
