The bacteriostatic method comprises the following steps: obtaining the temperature of the sewage tank; determining whether the temperature is higher than or equal to a first preset temperature; and when the temperature is higher than or equal to the first preset temperature, controlling a refrigeration mechanism to perform refrigeration and deliver cold energy to the sewage tank. In this way, when the temperature of the sewage tank is higher than or equal to the first preset temperature, the base station can automatically start the refrigeration mechanism to perform refrigeration and make the cold energy reach the inside of the sewage tank, thereby reducing the temperature of the sewage tank, inhibiting the growth and reproduction of microorganisms in the sewage tank, greatly reducing the probability of odor generation of the sewage tank, prolonging the cleaning interval length of the sewage tank, reducing the cleaning frequency of the sewage tank, and improving the user experience.

Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a method for inhibiting bacteria in a base station wastewater tank and a base station. Background Technology

[0002] Currently, some cleaning equipment (such as robotic vacuum cleaners) is equipped with base stations. These base stations are used to clean the cleaning equipment and are equipped with wastewater tanks to hold the wastewater from the cleaning process.

[0003] However, if the sewage in the base station's sewage tank is not cleaned for a long time, bacteria will multiply rapidly, producing an unpleasant odor. Furthermore, the excessive bacterial growth in the sewage tank makes it even more difficult to clean. Therefore, to avoid these problems, existing cleaning equipment requires frequent cleaning of the sewage tank, which reduces the user experience. Summary of the Invention

[0004] To address the problems existing in the aforementioned related technologies, this disclosure provides a method for inhibiting bacteria in a base station wastewater tank and a base station.

[0005] The first aspect of this disclosure provides a method for inhibiting bacteria in a base station wastewater tank, comprising:

[0006] The temperature of the sewage tank is obtained; it is determined whether the temperature is higher than or equal to the first preset temperature; when the temperature is higher than or equal to the first preset temperature, the refrigeration mechanism is controlled to perform refrigeration and deliver cold energy to the sewage tank.

[0007] Therefore, when the temperature of the sewage tank is higher than or equal to the first preset temperature, the base station can automatically activate the cooling mechanism to cool the sewage tank and allow the cold air to reach the inside of the sewage tank, thereby reducing the temperature of the sewage tank, inhibiting the growth and reproduction of microorganisms in the sewage tank, significantly reducing the probability of the sewage tank producing odors, extending the cleaning interval of the sewage tank, reducing the cleaning frequency of the sewage tank, and improving the user experience.

[0008] In some embodiments of this disclosure, the control of the refrigeration mechanism to perform refrigeration and deliver cooling capacity to the sewage tank includes:

[0009] Determine whether the base station is in sterilization mode; when the base station is in sterilization mode, control the cooling mechanism to cool and deliver cold energy to the sewage tank.

[0010] Therefore, by adding a sterilization mode judgment before performing the cooling and sterilization operation, users can decide whether to enable the sterilization function of the sewage tank, avoiding unnecessary power consumption in scenarios where sterilization is not needed (such as when users plan to manually clean the sewage tank in a short period of time), improving the accuracy of sewage tank sterilization function control, reducing base station energy consumption, and improving user experience.

[0011] In some embodiments of this disclosure, the control of the refrigeration mechanism to perform refrigeration includes:

[0012] Determine whether the base station is in drying mode; when the base station is in drying mode, control the cooling mechanism to cool at a first power; when the base station is in non-drying mode, control the cooling mechanism to cool at a second power, wherein the first power is greater than the second power.

[0013] Therefore, when the base station is in drying mode, the various components of the drying module generate noise during operation. At this time, the cooling mechanism is controlled to operate at higher power, and the noise generated by the cooling mechanism is masked by the noise of the drying mode. The noise perceived by the user is from the drying module, achieving imperceptible operation of the cooling mechanism. This cools the wastewater tank while avoiding noise interference with the user, thus achieving antibacterial properties in the wastewater tank and improving the user experience. Conversely, when the base station is in non-drying mode, the cooling mechanism is controlled to operate at lower power, reducing the noise of its operation. This also cools the wastewater tank while minimizing noise interference with the user, achieving antibacterial properties in the wastewater tank and further improving the user experience.

[0014] When a thermoelectric cooler is used in the drying module, the cooling capacity of the thermoelectric cooler's cooling end can be used to cool the wastewater tank. In this case, the cooling capacity generated by the thermoelectric cooler is at its maximum when the drying mode is on, and the cooling mechanism transfers cooling capacity to the wastewater tank at a higher power. When the base station is not in drying mode, a relatively lower cooling capacity is supplied, and the cooling mechanism transfers cooling capacity to the wastewater tank at a lower power, resulting in less noise.

[0015] In some embodiments of this disclosure, the control of the refrigeration mechanism to perform refrigeration and deliver cooling capacity to the sewage tank includes:

[0016] Control the operation of the refrigeration unit to generate cooling capacity; control the transfer of cooling capacity to the sewage tank.

[0017] Therefore, separating and independently controlling the refrigeration section and the cold energy transmission section can better control the transmission of cold energy and prevent excess cold energy from continuing to be transmitted to the sewage tank when it is not needed, especially when using the refrigeration end of the semiconductor drying equipment for refrigeration.

[0018] When the temperature of the sewage tank is higher than or equal to the first preset temperature, the refrigeration mechanism can be controlled to operate to generate cooling capacity, and the cooling capacity can be controlled to be transferred to the sewage tank to reduce the temperature of the sewage tank, inhibit the growth and reproduction of microorganisms in the sewage tank, and achieve antibacterial effect on the sewage tank.

[0019] In some embodiments of this disclosure, the control of cold energy transfer to the wastewater tank includes:

[0020] Control the start of the fan to transfer the cooling capacity generated by the refrigeration unit to the sewage tank;

[0021] And / or, control the movement of the intermediate heat-conducting component to connect the cooling component of the refrigeration mechanism with the heat sink disposed in the wastewater tank, so as to transfer the cold energy generated by the cooling component to the heat sink.

[0022] Therefore, the cooling capacity generated by the refrigeration mechanism can be transferred to the sewage tank by the air force generated by the fan; the refrigeration components of the refrigeration mechanism and the heat sinks set in the sewage tank are connected by an intermediate heat conduction component, and the cooling capacity generated by the refrigeration components is transferred to the heat sinks in the sewage tank through the intermediate heat conduction component. The cooling capacity can be transferred to the sewage tank through two cooling capacity transfer paths, which can further improve the accuracy and efficiency of cooling capacity transfer, improve the utilization rate of cooling capacity, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0023] In some embodiments of this disclosure, after the refrigeration mechanism performs refrigeration and delivers cooling capacity to the sewage tank, the method further includes:

[0024] Determine whether the temperature of the sewage tank is lower than or equal to the second preset temperature, where the second preset temperature is lower than the first preset temperature; when the temperature is lower than or equal to the second preset temperature, control the refrigeration mechanism to turn off refrigeration or block the refrigeration mechanism from supplying cooling energy to the sewage tank.

[0025] Therefore, when the temperature of the sewage tank is lower than or equal to the second preset temperature, the supply of cooling energy to the sewage tank can be stopped, which avoids the sewage tank from freezing due to excessively low temperature, reduces the energy consumption of the sewage tank for antibacterial purposes, saves energy, keeps the sewage in the sewage tank in an easy-to-clean state, and improves the service life of the sewage tank.

[0026] In some embodiments of this disclosure, the blocking cooling mechanism delivers cooling energy to the sewage tank, including:

[0027] Control the fan to shut down, thereby blocking the supply of cooling energy to the sewage tank;

[0028] And / or, control the movement of the intermediate heat-conducting component to disconnect the cooling component of the refrigeration mechanism and the heat sink provided in the wastewater tank, so as to block the transfer of cold energy to the heat sink.

[0029] Therefore, the fan can be shut down in a timely manner, and / or the connection between the cooling components of the refrigeration mechanism and the heat sink installed in the sewage tank can be disconnected in a timely manner, so as to stop the supply of cooling capacity to the sewage tank in a timely manner, avoid the sewage tank temperature from being too low and causing the sewage to freeze, reduce the energy consumption of the sewage tank for antibacterial purposes, save energy, keep the sewage in the sewage tank in an easy-to-clean state, and improve the service life of the sewage tank.

[0030] In some embodiments of this disclosure, obtaining the temperature of the wastewater tank includes:

[0031] Acquire temperature data from multiple temperature sensors inside the wastewater tank; average the multiple temperature data to obtain the temperature of the wastewater tank.

[0032] Therefore, by collecting data from multiple temperature sensors and averaging it, the temperature of the sewage tank can accurately reflect the true temperature level of the entire sewage tank, avoiding temperature misjudgment caused by the limited installation location of a single sensor and improving the accuracy of sewage tank temperature acquisition.

[0033] In some embodiments of this disclosure, the base station includes a thermoelectric cooler having a cooling end and a heating end, the heating end being used to provide heat for drying when the base station is in drying mode;

[0034] Before controlling the refrigeration unit to perform refrigeration and deliver cooling capacity to the sewage tank, the method further includes:

[0035] Determine whether the base station is in drying mode; when the base station is in drying mode, control the semiconductor cooling chip to operate at the third power so that the heating end provides heat for drying;

[0036] Controlling the refrigeration unit to perform refrigeration and deliver cooling capacity to the sewage tank includes:

[0037] The cooling capacity of the thermoelectric cooler is transferred to the wastewater tank.

[0038] Therefore, when the base station is in drying mode, the thermoelectric cooler is controlled to operate at a higher power so that the heating end of the thermoelectric cooler provides heat for drying. Furthermore, when the temperature of the wastewater tank is higher than or equal to a first preset temperature, the base station can automatically transfer the cooling energy from the cooling end of the thermoelectric cooler to the wastewater tank, thereby reducing the temperature of the wastewater tank, inhibiting the growth and reproduction of microorganisms in the wastewater tank, and achieving antibacterial treatment of the wastewater tank. By using the existing thermoelectric cooler for drying as the cooling mechanism for the wastewater tank, the heating end of the thermoelectric cooler is used for drying, and the cooling end of the thermoelectric cooler is used for antibacterial treatment of the wastewater tank. This can save energy, improve energy utilization, save base station space, reduce the number of base station components and the overall cost, and improve the compactness of the base station.

[0039] In some embodiments of this disclosure, the control of the refrigeration mechanism to perform refrigeration and deliver cooling capacity to the sewage tank includes:

[0040] When the base station is in non-drying mode, the control semiconductor refrigeration chip is operated at the fourth power, and the cooling capacity of the cooling end of the semiconductor refrigeration chip is transferred to the sewage tank. The fourth power is lower than the third power.

[0041] Therefore, when the temperature of the wastewater tank is higher than or equal to the first preset temperature, it is determined whether the base station is in drying mode. When the base station is in non-drying mode, the thermoelectric cooler is controlled to operate at low power, and the cooling capacity of the thermoelectric cooler is transferred to the wastewater tank. Operating at low power in non-drying mode ensures the antibacterial and cooling requirements of the wastewater tank while avoiding unnecessary heat and power consumption during periods when drying is not required, thus reducing the base station's standby power consumption and noise level.

[0042] In some embodiments of this disclosure, the step of controlling the thermoelectric cooler to operate at a fourth power and transferring the cooling capacity of the thermoelectric cooler's cooling end to the wastewater tank when the base station is in a non-drying mode includes:

[0043] When the base station is in non-drying mode, determine whether the base station is in sterilization mode; when the base station is in sterilization mode, control the semiconductor refrigeration chip to operate at the fourth power and transfer the cooling capacity of the refrigeration end of the semiconductor refrigeration chip to the sewage tank.

[0044] Therefore, when the temperature of the wastewater tank is higher than or equal to the first preset temperature and the base station is in non-drying mode, it is determined whether the base station is in sterilization mode. When the base station is in sterilization mode, the cooling capacity of the thermoelectric cooler is transferred to the wastewater tank. By adding a sterilization mode judgment before performing the cooling and sterilization operation, users can decide whether to enable the sterilization function of the wastewater tank, avoiding unnecessary power consumption in scenarios where sterilization is not needed (such as when users plan to manually clean the wastewater tank in a short period of time), improving the accuracy of the wastewater tank sterilization function control, reducing base station energy consumption, and improving the user experience. Furthermore, using the existing thermoelectric cooler used for drying as the cooling mechanism of the wastewater tank, with the heating end of the thermoelectric cooler used for drying and the cooling end used for sterilization of the wastewater tank, can save energy, improve energy utilization, save base station space, and improve the compactness of the base station.

[0045] A second aspect of this disclosure provides a base station, the base station comprising:

[0046] case;

[0047] Wastewater tank, mounted on the casing;

[0048] The refrigeration mechanism includes a refrigeration component disposed in the housing and a cold energy transfer unit for transferring cold energy to the sewage tank.

[0049] Therefore, by setting a cooling mechanism on the casing and configuring a cold energy transmission unit to connect the cooling component with the sewage tank, the base station has the ability to actively cool the sewage tank. When the temperature inside the sewage tank reaches or exceeds the range suitable for the growth of microorganisms, the cold energy transmission unit can transfer cold energy to the sewage tank to cool it down, inhibit the growth and reproduction of microorganisms in the sewage tank, significantly reduce the probability of the sewage tank producing odors, extend the cleaning interval of the sewage tank, reduce the cleaning frequency of the sewage tank, and improve the user experience.

[0050] In some embodiments of this disclosure, the sewage tank is provided with a heat sink, and the cold energy transfer unit includes a first heat-conducting component connected to the refrigeration component, a second heat-conducting component in thermal communication with the heat sink, and a heat-conducting control unit for controlling the conduction of the first heat-conducting component and the second heat-conducting component.

[0051] The heat conduction control unit includes an intermediate heat conduction component and a drive component that controls the movement of the intermediate heat conduction component. The drive component drives the intermediate heat conduction component to move to a heat conduction position and a non-heat conduction position. When in the heat conduction position, the intermediate heat conduction component is connected to the first heat conduction component and the second heat conduction component respectively.

[0052] In the non-heat-conducting position, the intermediate heat-conducting element is disconnected from at least one of the first and second heat-conducting elements.

[0053] Therefore, by switching the intermediate heat-conducting component of the heat-conducting control unit between the heat-conducting and non-heat-conducting positions, precise control of the on / off state of the cold energy transmission channel can be achieved. When it is necessary to cool and inhibit bacteria in the sewage tank, the drive unit pushes the intermediate heat-conducting component to the heat-conducting position, establishing a path for cold energy to the sewage tank; when it is not necessary to cool the sewage tank, the drive unit retracts the intermediate heat-conducting component to the non-heat-conducting position, cutting off the path for cold energy to the sewage tank. This on / off structure eliminates the need for frequent power-on and power-off at the cooling component, reducing thermal shock to the semiconductor cooling chip and extending its service life. It can improve the accuracy of cold energy transmission or disconnection control for the sewage tank, increase the utilization rate of cold energy, and achieve bacteria inhibition of the sewage tank.

[0054] In some embodiments of this disclosure, the base station further includes a temperature sensor and a control unit disposed within a sewage tank. The temperature sensor is electrically connected to the control unit, and the control unit is electrically connected to a drive component. The cooling component includes a semiconductor refrigeration chip, which has a cooling end and a heating end. A first heat-conducting component is connected to the cooling end. The base station also includes a drying module, which includes a cleaning component drying area and a heat transfer module. The heat transfer module is used to transfer heat from the heating end to the cleaning component drying area.

[0055] Therefore, the temperature sensor, control unit, and drive components form a closed-loop control chain for temperature acquisition, temperature judgment, and temperature control of the sewage tank, improving the accuracy of sewage tank temperature control and achieving antibacterial effects on the sewage tank. An existing semiconductor cooling chip used for drying is used as the cooling mechanism for the sewage tank, with the heating end of the semiconductor cooling chip used for drying and the cooling end used for antibacterial effects on the sewage tank. These two functions, which would traditionally be performed by separate modules, are integrated into a single semiconductor cooling chip in this application, saving internal space in the base station, reducing the number of components and the overall cost, and also avoiding the energy waste of residual heat from the heating end being ineffectively dissipated into the environment, thus improving energy utilization.

[0056] In some embodiments of this disclosure, the wastewater tank of the base station is provided with a cold air outlet, and the cold air transmission unit includes an air duct connecting the cooling component and the cold air outlet and a fan disposed in the air duct.

[0057] Therefore, by forming a fan duct through the cold air outlets on the refrigeration components and the sewage tank, the cold energy of the refrigeration components is transferred to the sewage tank through the duct. This can improve the cold energy transfer speed, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0073] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0074] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0077] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0078] To better understand the inventive concept of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be described below in conjunction with exemplary embodiments.

[0079] The antibacterial method for the base station wastewater tank provided in this embodiment can be executed by a base station. The base station can be understood as a device responsible for automatically charging, cleaning, drying, etc. of cleaning equipment (such as a robot vacuum cleaner). The base station is equipped with a wastewater tank for holding wastewater.

[0080] Figure 1 This is a flowchart illustrating a method for inhibiting bacteria in a base station wastewater tank, as provided in this embodiment. This method can be executed by a base station, such as... Figure 1 As shown, the antibacterial method for the base station wastewater tank provided in this embodiment includes the following steps:

[0081] Step 110: Obtain the temperature of the sewage tank.

[0082] The base station's wastewater tank is equipped with a temperature sensor that can collect the temperature of the wastewater inside. The base station can obtain the temperature of the wastewater tank through the temperature sensor according to a preset sampling period.

[0083] The preset sampling period can be set as needed, such as 30 seconds, but there is no limit here.

[0084] In some embodiments, a plurality of temperature sensors are provided inside the wastewater tank. These temperature sensors can be distributed at different locations inside the wastewater tank or its mounting cavity. The number of temperature sensors can be set as needed and is not limited here.

[0085] For example: a temperature sensor is set at the bottom center of the sewage tank to collect the sewage temperature at the bottom of the tank; a temperature sensor is set at the middle of the side wall of the sewage tank to collect the sewage temperature in the middle layer of the tank; and a temperature sensor is set at the top of the sewage tank to collect the temperature of the upper layer of the tank.

[0086] The base station can acquire temperature data from multiple temperature sensors inside the sewage tank; the average of these data points yields the tank's temperature. For example, a weighted average of the temperature data from multiple sensors can be calculated, and this weighted average is used to determine the sewage tank's temperature. The weights of the temperature sensors are determined based on their positions within the tank; a sensor's weight is negatively correlated with its distance from the bottom of the tank—the smaller the distance, the greater the sensor's weight.

[0087] Therefore, by collecting data from multiple temperature sensors and averaging it, the temperature of the sewage tank can accurately reflect the true temperature level of the entire sewage tank, avoiding temperature misjudgment caused by the limited installation location of a single sensor and improving the accuracy of sewage tank temperature acquisition.

[0088] Step 120: Determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0089] The base station stores a first preset temperature. The first preset temperature can be understood as the minimum temperature suitable for the growth and reproduction of microorganisms (such as bacteria). The first preset temperature can be set as needed, and is not limited here.

[0090] After obtaining the temperature of the sewage tank, the base station can determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0091] Step 130: When the temperature of the sewage tank is higher than or equal to the first preset temperature, control the refrigeration mechanism to perform refrigeration and deliver cold energy to the sewage tank.

[0092] When the temperature of the sewage tank is higher than the first preset temperature, it indicates that most microorganisms are in a state where they can actively reproduce. At this time, the base station can control the cooling mechanism to cool and deliver cold energy to the sewage tank to reduce the temperature of the sewage tank by the cold energy, so that the temperature of the sewage tank is lower than the first preset temperature, thereby making the temperature of the sewage tank unsuitable for the growth and reproduction of microorganisms, thus achieving the antibacterial effect.

[0093] When the temperature of the sewage tank is lower than the first preset temperature, it means that the temperature of the sewage tank is within the temperature range that inhibits the growth and reproduction of microorganisms. The base station can wait for the next preset sampling cycle to execute step 110 again without activating the cooling mechanism or maintaining the current state of the sewage tank.

[0094] Therefore, when the temperature of the sewage tank is higher than or equal to the first preset temperature, the base station can automatically activate the cooling mechanism to cool the sewage tank and allow the cold air to reach the inside of the sewage tank, thereby reducing the temperature of the sewage tank, inhibiting the growth and reproduction of microorganisms in the sewage tank, significantly reducing the probability of the sewage tank producing odors, extending the cleaning interval of the sewage tank, reducing the cleaning frequency of the sewage tank, and improving the user experience.

[0095] In some embodiments of this disclosure, when the temperature of the sewage tank is higher than or equal to a first preset temperature, it can be determined whether the base station is in sterilization mode. When the base station is in sterilization mode, the base station can control the cooling mechanism to cool and deliver cold energy to the sewage tank.

[0096] The sterilization mode (also known as the antibacterial mode) refers to the working state in which the base station inhibits bacteria in the sewage tank. The sterilization mode can be triggered by the user through a physical button on the base station, or it can be remotely activated by the user through an application on a mobile terminal that communicates with the base station. This application does not limit the triggering method of the sterilization mode.

[0097] Therefore, by adding a sterilization mode judgment before performing the cooling and sterilization operation, users can decide whether to enable the sterilization function of the sewage tank, avoiding unnecessary power consumption in scenarios where sterilization is not needed (such as when users plan to manually clean the sewage tank in a short period of time), improving the accuracy of sewage tank sterilization function control, reducing base station energy consumption, and improving user experience.

[0098] In some embodiments of this disclosure, when the temperature of the sewage tank is higher than or equal to a first preset temperature, it can be determined whether the base station is in drying mode;

[0099] When the base station is in drying mode, the base station can control the cooling mechanism to cool at the first power and deliver cooling capacity to the sewage tank;

[0100] When the base station is in non-drying mode, the base station can control the cooling mechanism to cool at a second power and deliver cooling capacity to the sewage tank, wherein the first power is greater than the second power.

[0101] The drying mode refers to the working state in which the base station's drying module is performing a drying operation on the cleaning components of the cleaning equipment (such as mops, roller brushes, etc.). The drying mode can be triggered by the user through a physical button on the base station, or it can be remotely activated by the user through an application on a mobile terminal that communicates with the base station. This application does not limit the triggering method of the drying mode.

[0102] In this embodiment, since the drying module's components generate noise when the base station is in drying mode, the cooling mechanism is controlled to operate at higher power. The noise generated by the cooling mechanism is masked by the noise of the drying mode, so the noise perceived by the user is from the drying module. This achieves imperceptible operation of the cooling mechanism, cooling the wastewater tank while avoiding noise interference to the user, thus achieving antibacterial properties in the wastewater tank and improving the user experience. Conversely, when the base station is in non-drying mode, the cooling mechanism is controlled to operate at lower power, reducing operating noise. This also reduces noise interference to the user while cooling the wastewater tank, achieving antibacterial properties in the wastewater tank and improving the user experience.

[0103] When a thermoelectric cooler is used in the drying module, the cooling capacity of the thermoelectric cooler's cooling end can be used to cool the wastewater tank. In this case, the cooling capacity generated by the thermoelectric cooler is at its maximum when the drying mode is on, and the cooling mechanism transfers cooling capacity to the wastewater tank at a higher power. When the base station is not in drying mode, a relatively lower cooling capacity is supplied, and the cooling mechanism transfers cooling capacity to the wastewater tank at a lower power, resulting in less noise.

[0104] In some embodiments of this disclosure, when the temperature of the sewage tank is higher than or equal to a first preset temperature, the operation of the refrigeration mechanism can be controlled to generate cooling capacity, and the cooling capacity can be controlled to be transferred to the sewage tank to reduce the temperature of the sewage tank, inhibit the growth and reproduction of microorganisms in the sewage tank, and achieve antibacterial effect on the sewage tank.

[0105] Therefore, separating and independently controlling the refrigeration section and the cold energy transmission section can better control the transmission of cold energy and prevent excess cold energy from continuing to be transmitted to the sewage tank when it is not needed, especially when using the refrigeration end of the semiconductor drying equipment for refrigeration.

[0106] In some embodiments, the base station is equipped with a fan. When the temperature of the sewage tank is higher than or equal to a first preset temperature, the cooling mechanism can be controlled to operate to generate cooling capacity, and the fan can be controlled to start to transfer the cooling capacity generated by the cooling mechanism to the sewage tank. That is, the cooling capacity generated by the cooling mechanism is transferred to the sewage tank by the wind force generated by the fan.

[0107] For example, the control unit in the base station outputs a start signal to the fan. After the fan starts, it generates a directional airflow inside the duct. The airflow is cooled when it passes through the heat exchange section where the cooling component connects to the duct (for example, heat dissipation fins are installed on the cooling end of the cooling component, and the airflow is cooled when it flows through the heat dissipation fins). The cooled airflow flows along the duct toward the sewage tank and is finally blown into the inner cavity of the sewage tank, forming a low-temperature air environment in the upper space of the sewage tank.

[0108] In some embodiments, the fan speed can be dynamically adjusted based on the difference between the temperature of the sewage tank and the first preset temperature: the greater the difference between the sewage tank temperature and the first preset temperature, the higher the fan speed; the smaller the difference between the sewage tank temperature and the first preset temperature, the lower the fan speed. This balances the cooling rate and operating noise.

[0109] Therefore, the cooling capacity generated by the refrigeration unit can be transferred to the sewage tank by the wind force generated by the fan, which can improve the speed of cooling capacity transfer, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0110] In some embodiments, the base station is provided with an intermediate heat-conducting component; the cooling mechanism includes a cooling component for generating cooling; and a heat sink is provided inside the wastewater tank. The intermediate heat-conducting component is used to connect or disconnect the cooling component of the cooling mechanism and the heat sink provided inside the wastewater tank.

[0111] When the temperature of the sewage tank is higher than or equal to the first preset temperature, the operation of the refrigeration mechanism can be controlled to generate cooling capacity, and the movement of the intermediate heat-conducting component can be controlled to connect the refrigeration component of the refrigeration mechanism and the heat sink installed in the sewage tank, so as to transfer the cooling capacity generated by the refrigeration component to the heat sink, and the heat sink transfers the cooling capacity to the sewage tank.

[0112] For example, the control unit in the base station outputs an action signal to the drive component in the heat dissipation control unit. The drive component then moves the intermediate heat-conducting component (also known as the heat-conducting slider) from a non-heat-conducting position to a heat-conducting position. Once the intermediate heat-conducting component reaches the heat-conducting position, the first heat-conducting component (one end connected to the cooling end of the cooling component) and the second heat-conducting component (one end connected to the heat sink in the wastewater tank) are connected in series through the intermediate heat-conducting component, forming a continuous metal heat conduction channel. Cooling energy is transferred along this heat conduction channel from the cooling end to the heat sink, where the heat sink contacts the wastewater in the wastewater tank for heat exchange, thereby reducing the temperature of the wastewater.

[0113] Therefore, the cooling components of the refrigeration mechanism and the heat sinks installed in the sewage tank can be connected through an intermediate heat-conducting component. The cooling energy generated by the cooling components is transferred to the heat sinks in the sewage tank through the intermediate heat-conducting component. The cooling energy is transferred through a solid medium throughout the process, and the cooling energy is not easily lost during the transfer. This can improve the accuracy and efficiency of cooling energy transfer, increase the utilization rate of cooling energy, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0114] In some embodiments, the base station is provided with a fan and an intermediate heat-conducting component; the cooling mechanism includes a cooling component for generating cooling capacity; and a heat sink is provided inside the wastewater tank. The intermediate heat-conducting component is used to connect or disconnect the cooling component of the cooling mechanism and the heat sink provided inside the wastewater tank.

[0115] When the temperature of the sewage tank is higher than or equal to the first preset temperature, the operation of the refrigeration mechanism can be controlled to generate cooling capacity, and the fan can be started to transfer the cooling capacity generated by the refrigeration mechanism to the sewage tank. At the same time, the intermediate heat conduction component is controlled to move to connect the refrigeration component of the refrigeration mechanism and the heat sink installed in the sewage tank, so as to transfer the cooling capacity generated by the refrigeration component to the heat sink, and the heat sink transfers the cooling capacity to the sewage tank.

[0116] Therefore, the cooling capacity generated by the refrigeration unit can be transferred to the sewage tank by the air force generated by the fan. At the same time, the refrigeration unit of the refrigeration unit and the heat sink set in the sewage tank are connected by the intermediate heat conduction component. The cooling capacity generated by the refrigeration unit is transferred to the heat sink in the sewage tank through the intermediate heat conduction component. The cooling capacity can be transferred to the sewage tank through two cooling capacity transfer paths, which can further improve the accuracy and efficiency of cooling capacity transfer, improve the utilization rate of cooling capacity, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0117] Figure 2 This is a flowchart illustrating a method for inhibiting bacteria in a base station wastewater tank, as provided in this embodiment. This method can be executed by a base station, such as... Figure 2 As shown, the antibacterial method for the base station wastewater tank provided in this embodiment includes the following steps:

[0118] Step 210: Obtain the temperature of the sewage tank.

[0119] Step 220: Determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0120] Step 230: When the temperature of the sewage tank is higher than or equal to the first preset temperature, control the refrigeration mechanism to perform refrigeration and deliver cold energy to the sewage tank.

[0121] Step 240: Determine whether the temperature of the sewage tank is lower than or equal to the second preset temperature, where the second preset temperature is lower than the first preset temperature.

[0122] After controlling the cooling mechanism to cool and supply cold energy to the sewage tank, the base station can determine whether the temperature of the sewage tank is lower than or equal to the second preset temperature.

[0123] The second preset temperature is lower than the first preset temperature. The second preset temperature can be understood as the preset freezing temperature of the wastewater. The second preset temperature can be set as needed, and is not limited here.

[0124] When the temperature of the wastewater tank is lower than or equal to the second preset temperature, the wastewater in the tank will freeze.

[0125] When the temperature in the sewage tank is higher than the second preset temperature, the sewage in the sewage tank will not freeze.

[0126] Step 250: When the temperature of the sewage tank is lower than or equal to the second preset temperature, control the refrigeration mechanism to turn off the refrigeration or block the refrigeration mechanism from supplying cold energy to the sewage tank.

[0127] In some embodiments, when the temperature of the sewage tank is lower than or equal to a second preset temperature, the base station can control the cooling mechanism to shut off the cooling in order to prevent the sewage in the sewage tank from freezing.

[0128] In other embodiments, when the temperature of the sewage tank is lower than or equal to a second preset temperature, in order to prevent the sewage in the sewage tank from freezing, the base station can block the cooling mechanism from delivering cold energy to the sewage tank.

[0129] In some embodiments, when the temperature of the sewage tank is between the second preset temperature and the first preset temperature, the base station can maintain the cooling mechanism in its current state without adjustment and wait for the next sampling cycle to re-evaluate.

[0130] Therefore, when the temperature of the sewage tank is lower than or equal to the second preset temperature, the supply of cooling energy to the sewage tank can be stopped, which avoids the sewage tank from freezing due to excessively low temperature, reduces the energy consumption of the sewage tank for antibacterial purposes, saves energy, keeps the sewage in the sewage tank in an easy-to-clean state, and improves the service life of the sewage tank.

[0131] In some embodiments, the base station is equipped with a fan. When the temperature of the sewage tank is lower than or equal to a second preset temperature, the base station can control the fan to shut down, thereby blocking the cooling mechanism from supplying cooling energy to the sewage tank.

[0132] For example, the base station's control unit outputs a stop signal to the fan. After the fan stops, there is no longer any directional airflow in the duct, and the cold energy generated at the cooling end of the cooling component cannot be carried to the sewage tank by the airflow. The sewage tank cavity no longer receives cold air from the duct.

[0133] In some embodiments, the base station is provided with an intermediate heat-conducting component; the cooling mechanism includes a cooling component for generating cooling; and a heat sink is provided inside the wastewater tank. The intermediate heat-conducting component is used to connect or disconnect the cooling component of the cooling mechanism and the heat sink provided inside the wastewater tank.

[0134] When the temperature of the sewage tank is lower than or equal to the second preset temperature, the base station can control the intermediate heat-conducting component to move to disconnect the cooling component of the cooling mechanism and the heat sink installed in the sewage tank, so as to block the cooling component from transferring cold energy to the heat sink.

[0135] For example, the control unit in the base station outputs a reset signal to the drive component in the thermal control unit. The drive component then drives the intermediate thermal conductive component (thermal conductive slider) to retract from the thermal conductive position to the non-thermal conductive position. In the non-thermal conductive position, the intermediate thermal conductive component breaks physical contact with at least one of the first and second thermal conductive components, creating a break in the heat conduction path. An air insulation gap is introduced into this break (air has a much lower thermal conductivity than metal), preventing the cold air from continuing to reach the heat sink through the heat conduction path.

[0136] In some embodiments, the base station is provided with a fan and an intermediate heat-conducting component; the cooling mechanism includes a cooling component for generating cooling capacity; and a heat sink is provided inside the wastewater tank. The intermediate heat-conducting component is used to connect or disconnect the cooling component of the cooling mechanism and the heat sink provided inside the wastewater tank.

[0137] When the temperature of the sewage tank is lower than or equal to the second preset temperature, the base station can control the fan to shut down and control the intermediate heat conduction component to move to disconnect the cooling component of the cooling mechanism and the heat sink installed in the sewage tank, so as to block the cooling mechanism from transferring cold energy to the heat sink.

[0138] Therefore, the fan can be shut down in a timely manner, and / or the connection between the cooling components of the refrigeration mechanism and the heat sink installed in the sewage tank can be disconnected in a timely manner, so as to stop the supply of cooling capacity to the sewage tank in a timely manner, avoid the sewage tank temperature from being too low and causing the sewage to freeze, reduce the energy consumption of the sewage tank for antibacterial purposes, save energy, keep the sewage in the sewage tank in an easy-to-clean state, and improve the service life of the sewage tank.

[0139] In some embodiments of this disclosure, the base station may include a thermoelectric cooler having a cooling end and a heating end, the heating end being used to provide heat for drying when the base station is in drying mode.

[0140] A thermoelectric cooler, also known as a semiconductor cooler, is a solid-state heat pump based on the Peltier effect. When direct current passes through a coupler composed of N-type and P-type semiconductor materials connected in series, heat is absorbed at one end (cooling end) and released at the other end (heating end) at the junction, thus achieving heat transfer and cooling. This device has no moving parts, produces no noise, requires no refrigerant, and features small size, high reliability, precise temperature control, and reversible hot and cold ends.

[0141] The cooling end of a semiconductor thermocouple is the end that absorbs heat when current passes through it. This end has a lower temperature and can be used to achieve cooling.

[0142] The heating end of a semiconductor thermocouple is the end that releases heat when current passes through it. This end has a higher temperature and can be used to generate heat.

[0143] Figure 3This is a flowchart illustrating a method for inhibiting bacteria in a base station wastewater tank according to an embodiment of this disclosure. This method can be executed by a base station, which may include a thermoelectric cooler having a cooling end and a heating end. The heating end is used to provide heat for drying when the base station is in drying mode. Figure 3 As shown, the antibacterial method for the base station wastewater tank provided in this embodiment includes the following steps:

[0144] Step 310: Obtain the temperature of the sewage tank.

[0145] Step 320: Determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0146] Step 330: When the temperature of the sewage tank is higher than or equal to the first preset temperature, determine whether the base station is in drying mode.

[0147] Step 340: When the base station is in drying mode, control the semiconductor cooling chip to operate at the third power so that the heating end of the semiconductor cooling chip provides heat for drying and transfers the cooling end of the semiconductor cooling chip to the sewage tank.

[0148] In this embodiment of the present disclosure, when the temperature of the wastewater tank is higher than or equal to the first preset temperature and the base station is in drying mode, the base station can control the semiconductor cooling chip to operate at the third power so that the heating end of the semiconductor cooling chip provides heat for drying. This heat is transferred to the cleaning part drying area via the heat transfer module, and the drying fan blows the heat onto the surface of the cleaning part to achieve rapid drying of cleaning parts such as mops or roller brushes. At the same time, the base station transfers the cooling end of the semiconductor cooling chip to the wastewater tank to provide cooling for the wastewater tank and reduce the temperature of the wastewater tank.

[0149] Therefore, when the base station is in drying mode, the thermoelectric cooler is controlled to operate at a higher power so that the heating end of the thermoelectric cooler provides heat for drying. Furthermore, when the temperature of the wastewater tank is higher than or equal to a first preset temperature, the base station can automatically transfer the cooling energy from the cooling end of the thermoelectric cooler to the wastewater tank, thereby reducing the temperature of the wastewater tank, inhibiting the growth and reproduction of microorganisms in the wastewater tank, and achieving antibacterial treatment of the wastewater tank. By using the existing thermoelectric cooler for drying as the cooling mechanism for the wastewater tank, the heating end of the thermoelectric cooler is used for drying, and the cooling end of the thermoelectric cooler is used for antibacterial treatment of the wastewater tank. This can save energy, improve energy utilization, save base station space, reduce the number of base station components and the overall cost, and improve the compactness of the base station.

[0150] Step 350: When the base station is in non-drying mode, control the semiconductor refrigeration chip to operate at the fourth power and transfer the cooling capacity of the cooling end of the semiconductor refrigeration chip to the sewage tank, wherein the fourth power is lower than the third power.

[0151] In this embodiment of the disclosure, when the base station is not in drying mode, the base station no longer needs to provide a large amount of heat to the cleaning component drying area. Therefore, the base station can reduce the power supply of the thermoelectric cooler, allowing it to operate at a lower fourth power. At this time, the cooling end of the thermoelectric cooler still generates cold energy (although the power is low, a certain temperature difference can still be maintained between the cooling end and the heating end through the Peltier effect). The cold energy generated by the cooling end of the thermoelectric cooler is transferred to the wastewater tank through the cold energy transmission unit.

[0152] Therefore, when the temperature of the wastewater tank is higher than or equal to the first preset temperature, it is determined whether the base station is in drying mode. When the base station is in non-drying mode, the thermoelectric cooler is controlled to operate at low power, and the cooling capacity of the thermoelectric cooler is transferred to the wastewater tank. Operating at low power in non-drying mode ensures the antibacterial and cooling requirements of the wastewater tank while avoiding unnecessary heat and power consumption during periods when drying is not required, thus reducing the base station's standby power consumption and noise level.

[0153] Figure 4 This is a flowchart illustrating a method for inhibiting bacteria in a base station wastewater tank according to an embodiment of this disclosure. This method can be executed by a base station, which may include a thermoelectric cooler having a cooling end and a heating end. The heating end is used to provide heat for drying when the base station is in drying mode. Figure 4 As shown, the antibacterial method for the base station wastewater tank provided in this embodiment includes the following steps:

[0154] Step 410: Obtain the temperature of the sewage tank.

[0155] Step 420: Determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0156] Step 430: When the temperature of the sewage tank is higher than or equal to the first preset temperature, determine whether the base station is in drying mode.

[0157] Step 440: When the base station is in drying mode, control the semiconductor cooling chip to operate at the third power so that the heating end of the semiconductor cooling chip provides heat for drying and transfers the cooling end of the semiconductor cooling chip to the sewage tank.

[0158] Step 450: When the base station is in non-drying mode, determine whether the base station is in sterilization mode.

[0159] Step 460: When the base station is in sterilization mode, control the semiconductor cooling chip to operate at the fourth power and transfer the cooling capacity of the cooling end of the semiconductor cooling chip to the sewage tank, wherein the fourth power is lower than the third power.

[0160] Therefore, when the temperature of the wastewater tank is higher than or equal to the first preset temperature and the base station is in non-drying mode, it is determined whether the base station is in sterilization mode. When the base station is in sterilization mode, the cooling capacity of the thermoelectric cooler is transferred to the wastewater tank. By adding a sterilization mode judgment before performing the cooling and sterilization operation, users can decide whether to enable the sterilization function of the wastewater tank, avoiding unnecessary power consumption in scenarios where sterilization is not needed (such as when users plan to manually clean the wastewater tank in a short period of time), improving the accuracy of the wastewater tank sterilization function control, reducing base station energy consumption, and improving the user experience. Furthermore, using the existing thermoelectric cooler used for drying as the cooling mechanism of the wastewater tank, with the heating end of the thermoelectric cooler used for drying and the cooling end used for sterilization of the wastewater tank, can save energy, improve energy utilization, save base station space, and improve the compactness of the base station.

[0161] Figure 5 This is a flowchart illustrating a method for inhibiting bacteria in a base station wastewater tank according to an embodiment of this disclosure. This method can be executed by a base station, which may include a thermoelectric cooler having a cooling end and a heating end. The heating end is used to provide heat for drying when the base station is in drying mode. Figure 5 As shown, the antibacterial method for the base station wastewater tank provided in this embodiment includes the following steps:

[0162] Step 510: Determine whether the base station is in sterilization mode.

[0163] Step 520: When the base station is in sterilization mode, obtain the temperature of the sewage tank.

[0164] Step 530: Determine whether the temperature of the sewage tank is higher than or equal to the first preset temperature.

[0165] Step 540: When the temperature of the sewage tank is higher than or equal to the first preset temperature, determine whether the base station is in drying mode.

[0166] Step 550: When the base station is in drying mode, control the semiconductor refrigeration chip to operate at the third power so that the heating end of the semiconductor refrigeration chip provides heat for drying, and control the driving component to drive the intermediate heat-conducting component to connect with the first heat-conducting component and the second heat-conducting component respectively, so as to transfer the cooling capacity of the cooling end of the semiconductor refrigeration chip to the sewage tank. The first heat-conducting component is connected to the cooling end of the semiconductor refrigeration chip, and the second heat-conducting component is thermally connected to the heat sink installed in the sewage tank.

[0167] Step 560: When the base station is in non-drying mode, control the semiconductor cooling chip to operate at the fourth power, and control the driving component to drive the intermediate heat-conducting component to connect with the first heat-conducting component and the second heat-conducting component respectively, so as to transfer the cooling capacity of the cooling end of the semiconductor cooling chip to the sewage tank, wherein the fourth power is lower than the third power.

[0168] Step 570: Determine whether the temperature of the sewage tank is lower than or equal to the second preset temperature, where the second preset temperature is lower than the first preset temperature.

[0169] Step 580: When the temperature of the sewage tank is lower than or equal to the second preset temperature, the control drive unit drives the intermediate heat-conducting component to disconnect from at least one of the first heat-conducting component and the second heat-conducting component, so as to stop the transfer of the cooling capacity of the cooling end of the semiconductor refrigeration chip to the sewage tank. The first heat-conducting component is connected to the cooling end of the semiconductor refrigeration chip, and the second heat-conducting component is thermally connected to the heat sink disposed in the sewage tank.

[0170] Therefore, by adding a sterilization mode judgment before performing the cooling and sterilization operation, users can decide whether to enable the sterilization function of the sewage tank, avoiding unnecessary power consumption in scenarios where sterilization is not needed (such as when users plan to manually clean the sewage tank in a short period of time), improving the accuracy of sewage tank sterilization function control, reducing base station energy consumption, and improving user experience.

[0171] When a thermoelectric cooler is used in the drying module, the cooling capacity of the thermoelectric cooler's cooling end can be used to cool the wastewater tank. In this case, when the drying mode is on, the cooling capacity generated by the thermoelectric cooler's cooling end is at its maximum, and the cooling mechanism transmits cooling capacity to the wastewater tank at a higher power. When the base station is not in drying mode, a relatively lower cooling capacity is supplied, and the cooling mechanism transmits cooling capacity to the wastewater tank at a lower power, resulting in less noise.

[0172] When the temperature of the wastewater tank is higher than or equal to the first preset temperature and the base station is in drying mode, the thermoelectric cooler is controlled to operate at a higher power so that the heating end of the thermoelectric cooler provides heat for drying. Furthermore, when the temperature of the wastewater tank is higher than or equal to the first preset temperature, the base station can automatically transfer the cooling energy of the cooling end of the thermoelectric cooler to the wastewater tank, reduce the temperature of the wastewater tank, inhibit the growth and reproduction of microorganisms in the wastewater tank, and achieve antibacterial treatment of the wastewater tank. By using the existing thermoelectric cooler used for drying as the cooling mechanism of the wastewater tank, the heating end of the thermoelectric cooler is used for drying, and the cooling end of the thermoelectric cooler is used for antibacterial treatment of the wastewater tank. This can save energy, improve energy utilization, save base station space, reduce the number of base station components and the overall cost, and improve the compactness of the base station.

[0173] When the temperature of the wastewater tank is higher than or equal to the first preset temperature and the base station is in non-drying mode, the semiconductor cooling chip is controlled to operate at a lower power, and the cooling capacity of the cooling end of the semiconductor cooling chip is transferred to the wastewater tank. Operating at low power in non-drying mode ensures the antibacterial and cooling requirements of the wastewater tank while avoiding unnecessary heat and power consumption during periods when drying is not required, thus reducing the standby power consumption and noise level of the base station.

[0174] When the temperature of the sewage tank is lower than or equal to the second preset temperature, the supply of cooling energy to the sewage tank is stopped to prevent the sewage from freezing due to excessively low temperature, reduce the energy consumption of the sewage tank for antibacterial function, save energy, keep the sewage in the sewage tank in an easy-to-clean state, and improve the service life of the sewage tank.

[0175] Figure 6 This is a schematic diagram of the structure of a base station provided in an embodiment of this disclosure. This base station is the base station for performing the above-described antibacterial method for a base station wastewater tank. Figure 6 As shown, the base station 600 includes:

[0176] Casing 10;

[0177] Wastewater tank 20 is installed on the shell 10;

[0178] The refrigeration mechanism 30 includes a refrigeration component 31 disposed in the housing and a cold energy transfer unit 32 for transferring cold energy to the sewage tank.

[0179] The housing serves as the main frame structure of the base station, accommodating and supporting its various functional modules. In some embodiments, the housing includes a cleaning station for cleaning equipment (such as a robotic vacuum cleaner) to return to and park, a wastewater tank installation cavity for placing a wastewater tank, and a cleaning component drying area for the drying module to operate.

[0180] A wastewater tank can be understood as a hollow container. The wastewater tank can be connected to the shell in a detachable manner, such as by a drawer-type sliding rail, a vertical snap-fit ​​connection, or magnetic positioning.

[0181] The refrigeration unit can be any of the following: a semiconductor refrigeration chip, a compression refrigeration module, or a Stirling refrigerator. The cold energy transfer unit is used to establish a cold energy transfer channel between the refrigeration unit and the wastewater tank.

[0182] Therefore, by setting a cooling mechanism on the casing and configuring a cold energy transmission unit to connect the cooling component with the sewage tank, the base station has the ability to actively cool the sewage tank. When the temperature inside the sewage tank reaches or exceeds the range suitable for the growth of microorganisms, the cold energy transmission unit can transfer cold energy to the sewage tank to cool it down, inhibit the growth and reproduction of microorganisms in the sewage tank, significantly reduce the probability of the sewage tank producing odors, extend the cleaning interval of the sewage tank, reduce the cleaning frequency of the sewage tank, and improve the user experience.

[0183] Figure 7a This is a schematic diagram of the structure of a base station provided in an embodiment of this disclosure, such as... Figure 7a As shown, the base station 700 includes:

[0184] Casing 10;

[0185] The sewage tank 20 is mounted on the shell 10, and a heat sink 21 is provided inside the sewage tank 20; for example, the heat sink can be installed on the inner surface of the bottom wall or side wall of the sewage tank by means of welding, snap-fit ​​or bolt fixing.

[0186] The refrigeration mechanism 30 includes a refrigeration component 31 disposed in the housing and a cold energy transfer unit 32 for transferring cold energy to the sewage tank;

[0187] The cold energy transfer unit 32 includes a first heat-conducting element 321, a second heat-conducting element 322, and a heat conduction control unit 323. The first heat-conducting element 321 is connected to the cooling element 31; the second heat-conducting element 322 is thermally connected to the heat sink 21; and the heat conduction control unit 323 controls the connection between the first heat-conducting element 321 and the second heat-conducting element 322.

[0188] like Figure 7b As shown in Figure 7b, this is a partial structural diagram of a base station. The first heat-conducting element 321 is connected to the cooling element 31, serving as a cold energy transmission channel. In some embodiments, the first heat-conducting element 321 is a metal heat-conducting pipe, one end of which is tightly fitted to the cooling end of the cooling element 31 (the contact interface can be filled with thermal grease to reduce interface thermal resistance), and the other end extends to the connection position of the heat-conducting control unit 323. In other embodiments, the outer surface of the first heat-conducting element 321 is covered with a heat-insulating material (e.g., polyurethane foam, aerogel insulation layer, or rubber-plastic insulation pipe) to reduce the loss of cold energy to the surrounding environment during transmission.

[0189] The second heat-conducting element 322 is thermally connected to the heat sink 21, serving as a channel for cold air transfer. One end of the second heat-conducting element 322 is attached to or fixed to the heat sink 21, and the other end extends to the connection position of the heat conduction control unit 323. The form of the second heat-conducting element is similar to that of the first heat-conducting element, and it can be a metal heat-conducting pipe or a heat-conducting block. The outer surface of the second heat-conducting element is also covered with heat-insulating material.

[0190] like Figure 7c As shown, 7c is a partial structural diagram of a base station. The heat conduction control unit 323 includes an intermediate heat conduction component 3231 and a driving component 3232 that controls the movement of the intermediate heat conduction component 3231. The driving component 3232 can drive the intermediate heat conduction component 3231 to move to a heat conduction position and a non-heat conduction position.

[0191] The intermediate heat-conducting component 3231 can be understood as a heat-conducting slider, and its material is a metal with high thermal conductivity. For example... Figure 8a As shown, Figure 8a This is a schematic diagram of a thermally conductive slider, wherein the thermally conductive slider 800 is provided with a sliding groove 801; as shown Figure 8b As shown, Figure 8bThis is a schematic diagram of a slide rail structure. The slide rail 802 is provided on the first heat-conducting component 321, and the slide groove 801 is installed in cooperation with the slide rail 802 provided on the first heat-conducting component 321, so that the heat-conducting slider 800 can reciprocate along the direction of the slide rail 802.

[0192] In this embodiment, cold energy is transferred via heat conduction. Heat is directly transferred through the direct contact between the cooling component 31, the first heat-conducting component 321, the heat-conducting slider 800, the second heat-conducting component 322, and the heat sink 21. Since cold energy transfer via heat conduction can be interrupted simply by disconnecting any two of these components, in other embodiments, the heat-conducting slider may not be necessary, and the first heat-conducting component 321 and the second heat-conducting component 322 can slide relative to the heat sink 21 or the cooling component 31 as a whole.

[0193] In other embodiments, the first heat-conducting element 321 and the second heat-conducting element 322 are always in contact but can slide relative to each other. During the sliding process, they still maintain a contact relationship. The first heat-conducting element 321 can be controlled to move away from the cooling end to disconnect the transfer of cold energy, or the second heat-conducting element 322 can be controlled to move away from the heat sink 21 to disconnect the transfer of cold energy.

[0194] Compared to other solutions, controlling the movement distance of the heat-conducting slider is the least expensive and has a relatively lower impact on other components.

[0195] In a specific embodiment, the driving component 3232 can be a drive motor, such as a stepper motor, to drive the heat-conducting slider to slide. In other embodiments, the drive motor can also cooperate with the first heat-conducting component 321 or the second heat-conducting component 322 to drive the corresponding component to move. It is understood that the driving component can also be a drive cylinder, etc.

[0196] When in the heat conduction position, the intermediate heat conduction element 3231 is in communication with the first heat conduction element 321 and the second heat conduction element 322 respectively; the intermediate heat conduction element 3231 forms surface contact with the first heat conduction element 321 and the second heat conduction element 322 respectively, and the three are connected in series to form a continuous metal heat conduction channel, and the cold energy is transferred from the cooling element 31 through the first heat conduction element 321, the intermediate heat conduction element 3231, the second heat conduction element 322 and the heat sink 21 to the sewage in the sewage tank.

[0197] In the non-heat-conducting position, the intermediate heat-conducting element 3231 is disconnected from at least one of the first heat-conducting element 321 and the second heat-conducting element 322.

[0198] In some embodiments, when in a non-heat-conducting position, the intermediate heat-conducting element may be disconnected from the first heat-conducting element.

[0199] In some embodiments, when in a non-heat-conducting position, the intermediate heat-conducting element may be disconnected from the second heat-conducting element.

[0200] In some embodiments, when in a non-heat-conducting position, the intermediate heat-conducting element may be disconnected from both the first and second heat-conducting elements.

[0201] Therefore, by switching the intermediate heat-conducting component of the heat-conducting control unit between the heat-conducting and non-heat-conducting positions, precise control of the on / off state of the cold energy transmission channel can be achieved. When it is necessary to cool and inhibit bacteria in the sewage tank, the drive unit pushes the intermediate heat-conducting component to the heat-conducting position, establishing a path for cold energy to the sewage tank; when it is not necessary to cool the sewage tank, the drive unit retracts the intermediate heat-conducting component to the non-heat-conducting position, cutting off the path for cold energy to the sewage tank. This on / off structure eliminates the need for frequent power-on and power-off at the cooling component, reducing thermal shock to the semiconductor cooling chip and extending its service life. It can improve the accuracy of cold energy transmission or disconnection control for the sewage tank, increase the utilization rate of cold energy, and achieve bacteria inhibition of the sewage tank.

[0202] In some embodiments of this disclosure, the base station further includes a temperature sensor and a control unit disposed inside the sewage tank; the temperature sensor is electrically connected to the control unit, and the control unit is electrically connected to the drive component;

[0203] For example, temperature sensors establish signal connections with the control unit via ribbon cables, flexible printed circuits, or wireless transmission modules. When the temperature sensor is a thermistor, its two ends are connected to the analog-to-digital conversion channel on the control unit's mainboard via a ribbon cable, and the control unit converts the acquired resistance value into the corresponding temperature value. When the temperature sensor is a digital semiconductor temperature sensor, it communicates with the control unit via a single-bus protocol or an Inter-Integrated Circuit (I2C) protocol.

[0204] For example, the control unit and the driving component are electrically connected via a circuit. The low-level control signal output by the control unit is amplified by the driving circuit and then drives the driving component to operate.

[0205] During operation, the temperature sensor can collect the temperature inside the sewage tank according to a preset sampling period and upload it to the control unit. The control unit compares the temperature value with the first preset temperature and the second preset temperature, and outputs the corresponding control signal to the drive unit. After receiving the signal, the drive unit drives the intermediate heat-conducting component to move to the heat-conducting position or the non-heat-conducting position, thereby realizing real-time on / off control of the cold energy transmission channel.

[0206] Therefore, the temperature sensor, control unit, and drive unit form a closed-loop control link for temperature acquisition, temperature judgment, and temperature control of the sewage tank, which improves the accuracy of temperature control of the sewage tank and achieves antibacterial effect on the sewage tank.

[0207] In some embodiments of this disclosure, the cooling element 31 includes a semiconductor cooling chip, such as... Figure 7bAs shown, the semiconductor cooling chip has a cooling end 311 and a heating end 312, and the first heat-conducting element 321 is connected to the cooling end 311;

[0208] In some embodiments, the contact end face of the first thermally conductive element 321 is in close contact with the cooling end 311 of the semiconductor refrigeration chip, and thermally conductive silicone grease or a phase change thermally conductive pad is filled between them to reduce the interface thermal resistance. In other embodiments, the first thermally conductive element 321 may also be directly fixed to the cooling end 311 by welding.

[0209] The aforementioned base station also has a drying module 40, such as Figure 7a As shown, the drying module includes a cleaning part drying area 41 and a heat transfer module 42. The heat transfer module 42 is used to transfer the heat from the heating end 312 of the semiconductor cooling chip to the cleaning part drying area 41.

[0210] The cleaning parts drying area is located on the housing near the cleaning parts parking position of the cleaning equipment. It is used to dry cleaning parts such as mops or rollers after the cleaning equipment has finished cleaning. In some embodiments, a hot air channel is provided on the inner wall of the cleaning parts drying area, and the air outlet of the hot air channel is directed towards the cleaning parts parking position.

[0211] A heat transfer module is used to transfer heat from the heating end of the semiconductor cooling chip to the cleaning part drying area. In some embodiments, such as Figure 7a As shown, the heat transfer module 42 includes a drying duct 421 and a drying fan 422. The drying fan 422 is used to send the heat from the heating end through the drying duct 421 into the cleaning part drying area by means of airflow.

[0212] In the above embodiments, the heat from the heating end is transferred to the drying area by thermal convection. In other embodiments, the heat can also be transferred directly through the contact of the components by thermal conduction. Specifically, the heat transfer module can also adopt a heat pipe structure: the evaporation section of one or more heat pipes is attached to the heating end, and the condensation section extends to the heat dissipation fins near the air inlet of the cleaning part drying area. The heat is transferred to the cleaning part drying area through the phase change heat transfer of the heat pipe, and then carried away by forced convection by the drying fan.

[0213] Therefore, the existing thermoelectric cooler used for drying is used as the cooling mechanism of the sewage tank, so that the heating end of the thermoelectric cooler is used for drying and the cooling end of the thermoelectric cooler is used for antibacterial treatment of the sewage tank. These two functions, which should have been completed by independent modules in the traditional structure, are integrated into the same thermoelectric cooler in this application, saving internal space of the base station, reducing the number of parts and the overall cost, and also avoiding the energy waste of the cold energy generated by the cooling end of the thermoelectric cooler being ineffectively dissipated into the environment, thus improving energy utilization.

[0214] In this embodiment, the heating end of the semiconductor cooling chip dries the cloth or roller, and then the cooling end of the semiconductor cooling chip generates cold energy to the sewage tank to cool it down. This fully utilizes the characteristics of the semiconductor cooling chip, achieving antibacterial properties in the sewage tank without increasing energy consumption, extending the deodorization period of the sewage tank, and improving the user experience.

[0215] It is understandable that, in other embodiments, the transfer of cooling capacity from the cooling end of the self-cooling component to the sewage tank can also be achieved through heat convection, specifically as follows: Figure 9 The diagram shown is a structural schematic of a base station provided in an embodiment of this disclosure. Figure 9 As shown, the base station 900 includes:

[0216] Casing 10;

[0217] Wastewater tank 20 is installed on the shell 10;

[0218] The refrigeration mechanism 30 includes a refrigeration component 31 disposed in the housing 10 and a cold energy transfer unit 32 that transfers cold energy to the sewage tank;

[0219] The wastewater tank 20 of the base station is equipped with a cold air outlet 22. The cold air transmission unit 32 includes an air duct 324 and a fan 325. The air duct 324 is used to connect the cooling component 31 and the cold air outlet 22, and the fan 325 is installed inside the air duct 324. That is, the cold air transmission unit 32 includes an air duct 324 connecting the cooling component 31 and the cold air outlet 22 and a fan 325 installed inside the air duct 324.

[0220] The cooling air outlet 22 is disposed on the wall of the sewage tank 20. In some embodiments, the cooling air outlet is disposed on the top cover of the sewage tank, near the rear side of the sewage tank mounting cavity, so that the cooling air blown into the sewage tank will not be directly impacted by the sewage flow. In other embodiments, the cooling air outlet may also be disposed on the upper half of the side wall of the sewage tank. This application does not limit the specific location of the cooling air outlet.

[0221] In some embodiments, louvers or air guide grilles may be installed at the cold air outlet 22 to guide the direction of the cold air blown into the sewage tank.

[0222] The air duct 324 is a sealed airflow channel connecting the cooling component 31 and the cold air outlet 22. In some embodiments, the air duct can be formed by a plastic component enclosing the housing, or it can be a separate air duct component fixed to the housing by clips or bolts. In some embodiments, the inner wall of the air duct can be covered with a layer of heat insulation material, such as polyurethane foam, to reduce heat exchange between the cold air and the outside environment during air duct transmission. In some embodiments, the inlet end of the air duct is arranged at the cooling end of the cooling component, and heat dissipation fins are attached to the cooling end, so that the air is cooled when it flows through the heat dissipation fins.

[0223] The fan is installed inside the air duct and is used to drive the air to flow along the duct. The fan can be an axial fan, a centrifugal fan, or a cross-flow fan, etc.

[0224] When in operation, the refrigeration component is powered on and cooled, and the heat dissipation fins at its cooling end are cooled. After the refrigeration fan is started, air is drawn into the air duct from the end of the refrigeration component and further cooled as it flows through the cooled heat dissipation fins. The cooled air is then transported through the air duct to the cold air outlet and blown into the inner cavity of the sewage tank from the cold air outlet.

[0225] Therefore, by forming a fan duct through the cold air outlets on the refrigeration components and the sewage tank, the cold energy of the refrigeration components is transferred to the sewage tank through the duct. This can improve the cold energy transfer speed, quickly reduce the temperature of the sewage tank, quickly inhibit the growth and reproduction of microorganisms in the sewage tank, and improve the antibacterial speed of the sewage tank.

[0228] In other embodiments, the base station can be a self-cleaning base station of a floor scrubber, whose wastewater tank collects wastewater after floor scrubbing and also faces the problem of odor generation if not cleaned for a long time.

[0229] In some embodiments, the base station can be a return cleaning station for a mopping robot, where fabric fibers may remain in the wastewater tank, making it easier for mold to grow.

[0230] In some embodiments, the base station may also be a wastewater storage module for a household dishwasher with a wastewater tank, a wastewater recycling module for a pet grooming machine, etc.
