Abstract
Description
Technical Field
[0001] This disclosure relates to a wet surface cleaning system. Background Technology
[0002] Wet surface cleaning equipment is suitable for cleaning hard floor surfaces, such as tile, hardwood floors, and soft carpet surfaces.
[0003] When cleaning a surface in a wet surface cleaning device, the cleaning liquid is first delivered to the cleaning module, and then applied to the surface through the cleaning module. When the cleaning module and the surface to be cleaned move relative to each other, the surface is cleaned.
[0004] To prevent odors and bacteria from growing in wet surface cleaning equipment, users typically place the wet surface cleaning equipment on a base station after it has finished cleaning, and the roller brush of the wet surface cleaning equipment is dried by the hot air provided by the base station.
[0005] During the drying process, the required power consumption and the time required are important performance parameters. They are not independent but closely related, and to some extent even inversely related; minimizing one necessarily comes at the expense of maximizing the other. In the final operation, the cleaned roller brush is dried within the roller brush chamber through a drying process.
[0006] Existing thermal drying methods use fixed drying times and energy inputs, which cannot adapt to changes in the humidity and temperature of the roller, resulting in excessive energy consumption or insufficient drying.
[0007] In addition, since the humidity and heat capacity of the roller brush vary with each use, fixed parameters cannot guarantee a stable drying effect, resulting in inconsistent drying effects of the roller brush.
[0008] When ambient temperature changes, such as when surface cleaning equipment is dried in summer and winter, fixed parameters can lead to inconsistent drying results. Additionally, changes in the base station's installation location can alter the humidity of the surrounding air, which also affects drying performance. Utility Model Content

[0042] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0043] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0044] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0045] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0046] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0047] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0048] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0049] The wet surface cleaning system disclosed herein may include a surface cleaning device and a base station. The surface cleaning device is configured to move on the surface to be cleaned, thereby cleaning the surface. The base station is configured for docking the surface cleaning device; when the surface cleaning device is docked at the base station, the base station can provide power to the surface cleaning device, and the base station can also perform self-cleaning of the roller brush 610 of the surface cleaning device.
[0050] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.
[0051] like Figure 1As shown, the surface cleaning device disclosed herein is configured to perform wet cleaning of a surface to be cleaned, wherein the surface to be cleaned can be a floor surface, preferably a household floor surface. Furthermore, after the surface cleaning device performs wet cleaning of the floor surface, the dirt and liquid (sewage) remaining from cleaning the surface can be recycled back to the surface cleaning device.
[0052] The surface cleaning device disclosed herein may include an upright body. Specifically, the upright body of the present disclosure may include a handle portion 100 and a main body portion 200. The handle portion 100 is detachably disposed on the main body portion 200. The user can operate the surface cleaning device by operating the handle portion 100, and the upright body can work in a manner substantially parallel to the surface to be cleaned during the operation of the surface cleaning device.
[0053] The handle 100 may be equipped with a user interaction button, which allows the user to control the surface cleaning equipment by triggering the button, such as controlling the start and stop of the surface cleaning equipment, as well as controlling the liquid supply speed and suction power of the suction source.
[0054] The main body 200 is pivotally connected to the floor brush assembly 600 via the connecting part 500; thus, when the user operates the handle part 100, the floor brush assembly 600 can be moved on the surface to be cleaned, and the surface to be cleaned can be cleaned by the floor brush assembly 600.
[0055] In one example, the connection 500 may include a universal joint to allow the main body 200 to rotate relative to the floor brush assembly 600 in two directions. In another example, the connection 500 may include a multi-axis joint that couples the main body 200 to the floor brush assembly 600 to allow the main body 200 to rotate relative to the floor brush assembly 600 along a first direction and a second direction.
[0056] The main body 200 can be pivoted to an upright position (also known as a storage position) via the connecting part 500. In this position, the angle between the main body 200 and the surface of the floor brush assembly 600 (or the ground) is 80° to 90°, preferably around 80°. In this position, the surface cleaning device is in a self-supporting posture (also known as an upright posture), meaning that the main body 200 and the like can be supported by the floor brush assembly 600, and an upright posture can be achieved without the aid of other objects.
[0057] The main body 200 can also accommodate components such as a clean water tank 300 and a recycling container 400. In this disclosure, the clean water tank 300 is detachably mounted to the side of the main body 200, and the mounting position can be located on the front side of the main body 200. The recycling container 400 is detachably mounted to the side of the main body 200, and the mounting position can be located on the rear side of the main body. In another embodiment, the clean water tank 300 of this disclosure can also be disposed on the floor brush assembly 600.
[0058] In one example, the thickness of the recycling tank container 400 is set to be less than its width, and the height of the clean water tank 300 is set to be less than its width. This ensures sufficient capacity and allows the overall height of the surface cleaning equipment to be less than a predetermined height, such as 120mm, after the main body 200 is laid flat.
[0059] The clean water tank 300 is used to store cleaning liquid (water). The water in the clean water tank 300 can be supplied to the floor brush assembly 600 of the surface cleaning device, or to the surface to be cleaned near the floor brush assembly 600, thereby enabling wet cleaning of the surface to be cleaned using the water in the clean water tank 300.
[0060] The main body 200 has a receiving space. The recycling tank container 400 is detachably installed in the main body 200 and located in the receiving space. When the recycling tank container 400 contains a large amount of liquid, the user can remove the recycling tank container 400, pour out the sewage inside, and clean up the solid waste. At this time, part of the outer surface of the recycling tank container 400 forms part of the outer surface of the surface cleaning device.
[0061] The floor brush assembly 600 disclosed herein may include a roller brush 610 and a suction nozzle; wherein the suction nozzle is located behind the roller brush 610, thereby allowing used water and dirt to enter the sludge inlet channel through the suction nozzle and further flow to the recycling tank container 400.
[0062] Figure 2 This is a schematic diagram of the structure of a floor brush assembly 600 of a surface cleaning device according to one embodiment of the present disclosure. Figure 3 This is a partial structural schematic diagram of a floor brush assembly 600 of a surface cleaning device according to one embodiment of the present disclosure.
[0063] The floor brush assembly disclosed herein may include a housing and a roller brush 610. The housing defines a roller brush cavity and a dirt inlet channel, the dirt inlet channel having a suction port. The roller brush 610 is rotatably disposed within the roller brush cavity, and the dirt inlet channel is generally located at the rear side of the roller brush 610. The suction port of the dirt inlet channel is disposed close to the roller brush, so that dirt on the roller brush 610 can be collected by the suction port and further flow through the suction port to the dirt inlet channel.
[0064] In addition, the surface cleaning device disclosed herein also includes a temperature detection mechanism 700, which includes at least one first temperature sensor mounted on the side wall of the dirt inlet channel, the at least one first temperature sensor facing and close to the roller brush 610.
[0065] Therefore, when the surface cleaning device disclosed herein is in use, it can detect the gas temperature of the roller brush in real time during the drying process through the first temperature sensor, and determine the degree of drying of the roller brush through the gas temperature, thereby realizing the dynamic adjustment of the drying process of the roller brush and avoiding the situation of insufficient drying or excessive drying that occurs in timed drying.
[0066] In other words, in the hot air drying method, the hot air drying device supplies hot air to the surface of the roller brush, but the moisture is not removed. The temperature of the air surrounding the surface of the roller brush rises during this process, causing the liquid on the roller brush surface to evaporate into the air near the roller brush.
[0067] In existing base station technologies, when hot air is used to dry the roller brushes of surface cleaning equipment, the drying time, temperature, and flow rate of the hot air provided during the drying process are independent of parameters such as the humidity and heat capacity of the roller brushes to be dried. In this case, a predetermined fixed time period needs to be set for the drying operation in the base station. For example, a constant drying time is set regardless of the roller brush temperature, and the heater is turned on and off periodically. The heater is switched on and off at timers, and drying is achieved through convection by an exhaust fan. The problem with this method is that the drying time is set to be constant, leading to inconsistent drying results. In other words, because the humidity and temperature of the roller brush surface vary each time, the required drying time and temperature also differ.
[0068] This presents a problem: drying performance degrades between the interval cycle and the heater drive cycle.
[0069] The wet surface cleaning system disclosed herein can optimize the drying operation of the wet surface cleaning system during use, and can achieve the most economical and technically simple drying. Moreover, the wet surface cleaning system disclosed herein does not require the use of technically complex sensors and / or dedicated drying equipment, etc., but only a temperature sensor can be used to optimize the drying process, thereby intelligently adjusting the drying time and achieving greater energy savings while thoroughly drying the roller brush.
[0070] In addition, the wet surface cleaning system disclosed herein can also obtain the temperature change of the roller brush by the temperature value detected by the temperature sensor during use, so as to avoid accidents caused by excessive temperature.
[0071] In some embodiments, at least one first temperature sensor is mounted on the side wall of the inlet channel away from the suction port, thereby enabling the first temperature sensor to detect the temperature of the gas in the inlet channel and thus obtain the state of the roller brush of the surface cleaning device based on the temperature of the gas in the inlet channel.
[0072] In another embodiment, at least one first temperature sensor is mounted on the side wall of the inlet channel near the suction port, thereby enabling the first temperature sensor to more accurately determine the state of the roller brush of the surface cleaning device by detecting the temperature near the roller brush.
[0073] In practical use, multiple first temperature sensors can be configured, and one of these temperature sensors can be positioned near the roller brush, for example, positioned in... Figure 3 On the side wall near the suction port.
[0074] In one specific embodiment, at least one first temperature sensor is a thermocouple sensor, an infrared temperature sensor, or a thermistor sensor, and preferably, at least one first temperature sensor is a non-contact temperature sensor used to detect the air temperature near the roller brush 610, and correspondingly, it can also directly detect the temperature of the roller brush 610 itself.
[0075] The wet surface cleaning system disclosed herein may further include a control module, which can be installed in the surface cleaning equipment or in the base station. Specifically, the control module of this disclosure may be two, with one control module (i.e., the first control module 800) installed in the surface cleaning equipment and the other control module (i.e., the second control module 910) installed in the base station.
[0076] In one embodiment, a first control module 800 is communicatively connected to at least one first temperature sensor. The first control module 800 includes a microprocessor and a memory, with the memory connected to the microprocessor. The at least one first temperature sensor is connected to the microprocessor, thereby transmitting the data detected by the first temperature sensor to the first control module 800, and further transmitting it to a second control module 910 via a communication module (e.g., a connection terminal) connected to the first control module 800. Then, the second control module 910 can control the start / stop and power of the hot drying device 930 according to the temperature detected by the first temperature sensor, thereby optimizing the drying process of the surface cleaning equipment.
[0077] Specifically, the base station disclosed herein includes a thermal drying device 930, which is configured to supply gas to the roller brush 610 of the ground brush assembly 600, thereby drying the roller brush 610 with the gas supplied by the base station.
[0078] In one implementation, the base station of this disclosure may further include a second temperature sensor 920, which is disposed near the thermal drying device 930. The second temperature sensor 920 is configured to detect the temperature of the gas supplied to the roller brush 610 of the floor brush assembly 600. That is, by using the second temperature sensor 920, the operating status of the thermal drying device 930 can be accurately determined. Therefore, the second control module 910 can accurately determine the status of the roller brush of the surface cleaning device, i.e., whether the roller brush of the surface cleaning device has been dried, based on the temperature value detected by the second temperature sensor 920 and the temperature value detected by the first temperature sensor.
[0079] For example, when the difference between the temperature value detected by the second temperature sensor 920 and the temperature value detected by the first temperature sensor is greater than or equal to a preset threshold, it indicates that the roller brush of the surface cleaning device is still wet. In this case, hot air needs to be continued to be supplied to the roller brush to dry it. On the other hand, when the difference between the temperature value detected by the second temperature sensor 920 and the temperature value detected by the first temperature sensor is less than the preset threshold, it indicates that the roller brush of the surface cleaning device has been dried or is close to being dried. In this case, the supply of hot air can be stopped or the power of the hot drying device 930 can be reduced to reduce the temperature and flow rate of the hot air supplied to the roller brush.
[0080] In one embodiment, the second temperature sensor 920 is electrically connected to the second control module 910, and the heat drying device 930 is also electrically connected to the second control module 910.
[0081] Based on the above structure, in use, the wet surface cleaning system of this disclosure has a roller brush surface covered with adsorbed lint, and a first temperature sensor detects temperature changes related to the lint, providing a basis for judging the dry state.
[0082] The base station disclosed herein is used to house the floor brush assembly. A thermal drying device is located inside the base station, near the roller brush, and is capable of supplying hot air to the roller brush. The thermal drying device may employ an electric heating element, transferring heat to the roller brush surface through air convection, causing the moisture adsorbed in the bristles to evaporate. A second control module is electrically connected to the thermal drying device to ensure that the heat output is coordinated with the temperature detection data. A first temperature sensor detects the air temperature (non-contact design) or surface temperature (contact design) near the roller brush, providing real-time feedback for dynamic adjustment. A second temperature sensor is installed on the base station to detect the air temperature (non-contact design) or surface temperature (contact design) near the electric heating element, providing real-time feedback for dynamic adjustment.
[0083] The control module's memory stores preset temperature parameters and drying mode data. The microprocessor receives data from the temperature sensor, calculates the temperature-time relationship or temperature difference, and then determines the drying status of the roller brush. For example, the first temperature sensor detects the air temperature near the roller brush, and the second temperature sensor detects the output temperature of the thermal drying device; the difference between the two reflects the efficiency and progress of the drying process.
[0084] Based on the wet surface cleaning system of this disclosure, the automatic drying of this disclosure is divided into the following methods:
[0085] In one approach, the degree of drying is inferred by the temperature value detected by a first temperature sensor (brush temperature sensor) installed on the brush to detect temperature changes during the drying process. The brush temperature sensor transmits the detected temperature to a first control module and a second control module in real time. The second control module can determine the drying progress according to a pre-set control algorithm, thereby controlling the operation of the hot drying device.
[0086] Alternatively, the degree of drying is inferred from the temperature values detected by two or more first temperature sensors installed on the roller brush to detect temperature changes during the drying process. At least one first temperature sensor is located away from the suction inlet, and one temperature sensor is located near the suction inlet. The temperature sensor located away from the suction inlet (far-inlet temperature sensor) and the temperature sensor located near the suction inlet (near-inlet temperature sensor) transmit the detected temperatures in real time to the control module of the surface cleaning system. The control module can determine the drying progress according to a pre-set control algorithm, thereby controlling the operation of the thermal drying device.
[0087] Here, the first and second positions on the sidewall where the distal and proximal temperature sensors are configured are the positions that best detect temperature changes along the longitudinal axis of the roller as the drying process progresses.
[0088] As the drying process continues, there will be a significant temperature difference between the first and second positions. This is because the circulating air through the brush chamber causes slower evaporation on the brush surface near the suction port and the brush surface far from the suction port, resulting in a lower temperature at the second position compared to the first position.
[0089] At the start of drying, the bristles on the surface of the roller brush contain a large amount of moisture, and under these conditions, the temperature difference detected between the first and second positions is relatively small.
[0090] During the intermediate drying stage, the temperature of the brush chamber rises as hot air is continuously drawn in to remove moisture from the bristles on the brush surface within the brush chamber, causing the hot, humid air to be discharged outwards.
[0091] At this point, due to the relatively large gap between the suction port and the roller brush, the airflow velocity and the large upper area result in a relatively strong evaporation effect.
[0092] As the drying process nears its end, the moisture in the bristles of the roller brush has been reduced to a certain extent. Near the suction port, the bristles on the roller brush surface are in a highly dry state, resulting in less residual water. Under these conditions, the temperature sensor located at the second position is affected by increased evaporation, thus detecting a larger temperature difference between the first and second positions.
[0093] Thus, the temperatures measured by the distal end temperature sensor and the proximal end temperature sensor are roughly the same at the beginning and middle stages of the drying process. However, at the end of the drying process, the temperature measured by the proximal end temperature sensor gradually increases, while the temperature measured by the distal end temperature sensor does not increase significantly because the evaporation is not yet complete. Therefore, the temperature difference measured by the two temperature sensors gradually widens.
[0094] When the temperature difference detected by the two temperature sensors reaches a certain level, the control unit will determine that the drying process is complete.
[0095] Alternatively, the temperature difference is calculated by the difference between the temperature value detected by a heat drying temperature sensor (i.e., a second temperature sensor) located near the drying circulation channel and the temperature value detected by a roller brush temperature sensor installed on the roller brush to detect temperature changes during the drying process.
[0096] In the automatic drying control according to the first embodiment of the present disclosure, when the drying operation starts, the control module periodically calculates the temperature difference from the time point when the temperature change detected by the roller brush temperature sensor exceeds a predetermined amount, or from the time point after a predetermined time has elapsed since the start of the drying operation. The calculation formula is: temperature difference = temperature value detected by the heat drying temperature sensor - temperature value detected by the roller brush temperature sensor.
[0097] Ideally, the system will correct the temperature data and calculate the dryness determination value once the temperature sensor readings stabilize after the drying operation begins (i.e., at the coolant supply point used for drying).
[0098] When the rotation cycle of the roller brush motor set by the program is detected and repeated a predetermined number of times, the average value of the temperature difference in the corresponding segment is calculated. This temperature difference is calculated and stored using temperature data from the heat drying temperature sensor and the roller brush temperature sensor detected in the corresponding segment.
[0099] At the end of the roller brush motor's rotation cycle, the processor averages the segment values to minimize the impact of the first and second rotation cycles of the roller brush motor on the temperature data values.
[0100] When the average value of each section is calculated and used as the dryness determination value, the data jitter is reduced and stabilized.
[0101] The average value of each section is used as the dryness determination value and compared with the standard value set according to the corresponding drying mode.
[0102] The comparison results show that if the average value of the section does not meet the selected drying mode, the temperature difference between the detected temperatures of the hot drying temperature sensor and the roller brush temperature sensor (temperature difference = detected temperature value of the hot drying temperature sensor - detected temperature value of the roller brush temperature sensor) is calculated in the processor and stored, and then the above steps are repeated.
[0103] If the average value of the sections meets the selected drying mode during the comparison step, the drying operation is stopped. In this case, when the average value of the sections is used as the dryness determination value and compared with the standard value set according to the corresponding drying mode, if the standard value is detected to be less than the dryness determination value twice consecutively, the required dryness is considered to have been achieved. This is to improve the accuracy of dryness determination.
[0104] When drying is performed in accordance with the controls described above in this disclosure, if the drying time reaches the limit (30 minutes or more), or if one of the detected temperature values exceeds the drying limit, the drying operation will be terminated for safety reasons, regardless of the degree of dryness.
[0105] The accuracy of drying operations in wet surface cleaning equipment has been improved by stabilizing the temperature data used to determine dryness, by increasing the resolution, and by determining additional drying time to achieve precise drying for all weights.
