Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a dehumidification device, cleaning equipment, and dehumidification method. Background Technology

[0002] With the widespread use of cleaning equipment in daily life and work, cleaning equipment greatly saves users' cleaning time and reduces their daily cleaning burden.

[0003] Specifically, the cleaning equipment includes cleaning robots and base stations. After working for a period of time, the cleaning robot needs to return to the base station to recharge. The base station is equipped with a dust collection bin, which can collect the debris from the cleaning robot's dust box into the dust collection bin for the robot's next operation.

[0004] However, if garbage is stored in the dust collection bin for a period of time, it is prone to oxidation and decomposition in humid air, making it difficult to meet the goal of not needing to empty the bin for 30 days. At the same time, long-term storage of wet dust or perishable garbage in a humid environment will cause the dust collection bin to become a breeding ground for mosquitoes due to the stench of decay, greatly reducing the user's product experience.

[0005] To solve the above problems, there is an urgent need to provide a dehumidification device, cleaning equipment, and dehumidification method to address these issues. Summary of the Invention

[0008] The third objective of this invention is to propose a dehumidification method that facilitates the removal of hot air and moisture from the dust collection chamber, thereby ensuring that the humidity inside the dust collection chamber is maintained at a normal temperature and low humidity environment. This prevents the dust collection chamber from becoming damp or rotting due to excessive humidity or temperature, thus extending the storage time of the dust and dust bags, reducing the frequency of users emptying the dust and replacing the dust bags, and preventing the generation of condensate due to uneven local temperature and humidity in the dust collection chamber.

[0032] As an alternative, the sensing element is a temperature sensing element and / or a humidity sensing element.

[0033] A cleaning device, comprising:

[0034] A cleaning robot, configured to clean the floor;

[0035] A base station is configured to charge the cleaning robot and collect waste within the cleaning robot, the base station including the dehumidification device described above.

[0036] A dehumidification method includes the following steps:

[0037] S1, The sensor detects the humidity and / or moisture content inside the dust collection chamber;

The exhaust component is located at the end of the connecting component furthest from the dust collection chamber. When the humidity detected by the sensor reaches a preset humidity value, the exhaust component opens the connecting component to extract moisture and / or hot air from the dust collection chamber. This dehumidification device prevents waste or dust bags from easily oxidizing and becoming damp in humid air, leading to rotting and dust leakage, thereby extending the storage time of waste and dust bags and reducing the frequency of waste disposal and dust bag replacement for users. By reducing humidity in the dust collection chamber through the exhaust fan, the dehumidifier prevents the long-term storage of damp dust or perishable waste in a humid environment from producing rotten odors.

The dehumidification method reduces the humidity of the dust collection chamber through an exhaust fan, preventing the long-term storage of wet dust or perishable garbage in a humid environment from producing a rotten odor. This also prevents the dust collection chamber from becoming a breeding ground for insects, significantly improving the user experience and enhancing the cleanliness of the dehumidification device, thus improving the user experience. Simultaneously, this dehumidification method also maintains a normal temperature inside the dust collection chamber, preventing uneven temperature and humidity in certain areas from causing condensation.

[0064] Example 1

[0065] With the widespread use of cleaning equipment in daily life and work, cleaning equipment greatly saves users' cleaning time and reduces their daily cleaning burden.

[0066] This embodiment provides a cleaning device. With the widespread application of cleaning devices in daily life or work, cleaning devices greatly save users' cleaning time and reduce users' daily cleaning burden.

[0067] like Figure 1 As shown, the cleaning equipment includes a cleaning robot and a base station 1000. After working for a period of time, the cleaning robot needs to return to the base station 1000 for charging. Meanwhile, the base station 1000 includes a dust collection component 500. When the cleaning robot returns to the base station 1000 to charge, the dust collection component 500 can collect the debris inside the cleaning robot. Specifically, the cleaning robot includes a dust box, the base station 1000 includes a dust collection chamber 100 with a dust collection port, and the dust collection component 500 includes a dust collection drive component 510 connected to the dust collection port. When the dust collection drive component 510 operates, it generates suction on the dust collection chamber 100, sucking the debris from the dust box into the dust collection chamber 100.

[0068] Meanwhile, due to the suction force of the dust collection drive 510, negative pressure is generated in the dust collection chamber 100 and the dust box. In order to replenish air into the dust box to improve the efficiency of the dust collection component 500 in recycling garbage, an air replenishment port is also provided on the dust collection chamber 100. The base station 1000 also includes an air replenishment channel 600. One end of the air replenishment channel 600 is connected to the air replenishment port of the dust collection chamber 100, and the other end is connected to the suction port of the dust box for sucking up garbage, so as to replenish air into the dust box and the dust collection chamber 100 in a timely manner, thereby balancing the air pressure.

[0069] Optionally, since the gas drawn out by the dust collection drive unit 510 under negative pressure is discharged into the base station 1000, it is not conducive to the long-term use of the components of the base station 1000. Therefore, the dust collection assembly 500 also includes a dust collection channel 520, one end of which is connected to the dust collection drive unit 510 and the other end is connected to the dust box, so as to guide the gas drawn out by the dust collection drive unit 510 into the dust box, so as to replenish the air pressure in the dust box and generate blowing force, thereby improving the dust collection efficiency of the dust collection assembly 500.

[0070] like Figures 1-3 As shown, this embodiment provides a dehumidification device, which includes a housing 300 for housing and protecting the internal structure. The dust collection bin 100 is a housing structure to increase its capacity for holding waste, and an exhaust vent 110 is provided on the dust collection bin 100. The dehumidification device is used to dehumidify the dust collection bin 100. The dehumidification device also includes a connecting component 200, a sensor, and an exhaust component 400. The sensor is disposed on the dust collection bin 100, the connecting component 200 is connected to the exhaust vent 110, and the exhaust component 400 is electrically connected to the sensor. The exhaust component 400 is located at the end of the connecting component 200 away from the dust collection bin 100. When the humidity detected by the sensor reaches a preset humidity value, the exhaust component 400 can open the connecting component 200 to extract moisture and / or hot air from the dust collection bin 100. This dehumidification device prevents waste or dust bags from easily oxidizing and becoming damp in humid air, leading to rotting and dust leakage, thereby extending the storage time of waste and dust bags and reducing the frequency of users emptying waste and replacing dust bags. The ventilation component 400 reduces the humidity of the dust collection chamber 100. The dehumidifier prevents the long-term storage of damp dust or perishable waste in a humid environment from producing a rotten odor, thus preventing the dust collection chamber 100 from becoming a breeding ground for mosquitoes and greatly reducing the user's product experience. This improves the cleanliness of the dust collection chamber and enhances the user experience. Simultaneously, the dehumidifier maintains a normal temperature within the dust collection chamber 100, preventing condensation caused by uneven temperature and humidity in certain areas.

[0071] The dehumidification device described above helps improve the cleanliness and user experience of the cleaning equipment.

[0072] Furthermore, since the cleaning components of the cleaning robot remain moist while cleaning the floor, they are prone to mold and even damage if left damp for extended periods when not in use. Therefore, the dehumidification device also includes a drying component to dry the cleaning components. It is understood that the cleaning components can be a cloth or a roller brush, etc. Specifically, the drying component includes a heating element that heats the air to dry the cleaning components.

[0073] As an alternative, the dust collection chamber 100 includes a chamber body 120 and a filter element 130, with an exhaust port 110 located on one side of the chamber body 120 for connection with the connecting assembly 200. The filter element 130 covers the exhaust port 110 to filter hot air and / or moisture flowing from the exhaust port 110.

[0074] It is understood that the sensors are temperature sensors and / or humidity sensors to detect the temperature or humidity of the dust collection chamber 100, or to detect both humidity and temperature simultaneously.

[0075] Now combined Figures 1-3 The detailed structure of the exhaust assembly 400 is explained.

[0076] like Figures 1-3 As shown, the exhaust assembly 400 includes a fan 410 and a duct 420. The fan 410 is electrically connected to the sensor, and the duct 420 is connected to the fan 410 and the external environment of the dehumidification device. When the exhaust assembly 400 is started, moisture and / or hot air can flow to the external environment along the duct 420 to achieve airflow. This avoids heating the internal structure of the cleaning equipment by moisture or hot air, which helps to maintain the overall cleaning equipment at a suitable temperature and humidity and improves the service life of the cleaning equipment.

[0077] Specifically, the dredging pipe 420 includes a main pipe 421 and at least one branch pipe 422. One end of the main pipe 421 is connected to the fan 410, and one end of the at least one branch pipe 422 is connected to the main pipe 421 and to the external environment. For example, in this embodiment, there are two branch pipes 422, one end of which is simultaneously connected to the main pipe 421, and both branch pipes 422 simultaneously divert airflow, delivering hot air and / or moisture to the outside through the two branch pipes 422.

[0078] As an optional solution, due to the limited internal space of the base station 1000, to save space, the exhaust assembly 400 and the drying assembly share a common drainage pipe 420. Specifically, the end of the drainage pipe 420 of the exhaust assembly 400 furthest from the fan 410 is connected to the cleaning component, and the heating element is located within the drainage pipe 420, and the heating element can be selectively activated. That is, when drying is not required, only the fan 410 can operate to dehumidify the dust collection chamber 100. When drying the cleaning component is required, the heating element can operate simultaneously with the fan 410, so that while dehumidifying the dust collection chamber 100, the heating element can also dry the cleaning component. At the same time, the blowing force of the fan 410 can be used to blow the air heated by the heating element towards the cleaning component, which can also improve the efficiency of drying the cleaning component.

[0079] Now combined Figure 2 and Figure 3 The detailed structure of the connecting component 200 is described below.

[0080] like Figure 2 and Figure 3 As shown, the connecting assembly 200 includes a connecting pipe 210 and a one-way valve 220. The two ends of the connecting pipe 210 are connected to the exhaust port 110 and the fan 410, respectively, to facilitate airflow and prevent leakage. The one-way valve 220 is embedded within the connecting pipe 210, and rotation of the fan 410 opens the one-way valve 220, allowing airflow from the exhaust port 110 towards the fan 410, preventing external hot air or moisture from entering the dust collection chamber 100.

[0081] More specifically, the one-way valve 220 includes a mounting portion 221, a connecting portion 222, and an outlet portion 223. The mounting portion 221 is embedded in the inner diameter of the connecting pipe 210, and one end of the mounting portion 221 is connected to the exhaust port 110. One end of the connecting portion 222 is connected to the end of the mounting portion 221 away from the exhaust port 110, and the diameter of the connecting portion 222 gradually decreases along the direction away from the exhaust port 110. The outlet portion 223 is connected to the connecting portion 222. This one-way valve 220 structure can increase the air pressure exerted by the airflow from the fan 410 on its suction, thereby increasing the suction force for extracting hot air / moisture.

[0082] Furthermore, the one-way valve 220 also includes a flexible part, which is provided at the outlet 223 and has an opening. The opening can be opened by the rotation of the exhaust assembly 400. The flexible part can improve the stability of the opening of the one-way valve 220 when the fan 410 rotates, and can improve the sealing performance of the opening when the fan 410 is turned off.

[0083] Example 2

[0084] like Figure 4 As shown, this embodiment provides a dehumidification method, which includes the following steps:

[0085] S1, the sensor detects the humidity and / or moisture content inside the dust collection chamber 100;

[0086] S2, when the temperature and / or humidity in the dust collection chamber 100 is higher than or equal to a preset value, the exhaust fan 400 is activated; and

[0087] S3, the connecting component 200 connects the exhaust component 400 and the dust collection chamber 100, and the moisture dust collection chamber 100 is drawn outward along the connecting component 200 and the exhaust component 400.

[0088] This dehumidification method prevents garbage or dust bags from oxidizing and becoming damp in humid air, which can lead to rotting and dust leakage. This extends the storage time of garbage and dust bags, reducing the frequency of garbage disposal and dust bag replacement for users. The dehumidification method uses the exhaust fan 400 to reduce the humidity of the dust collection chamber 100, preventing the long-term storage of wet dust or perishable garbage in a humid environment from producing a rotten odor. This also prevents the dust collection chamber 100 from becoming a breeding ground for insects, significantly improving the user experience and enhancing the cleanliness of the dehumidification device. Simultaneously, this dehumidification method also maintains a normal temperature inside the dust collection chamber 100, preventing uneven temperature and humidity that could cause condensation.

[0089] More importantly, this dehumidification method only activates the fan 410 when the temperature and / or humidity in the dust collection chamber 100 reach preset values, which helps save energy and avoids the continuous operation of the exhaust assembly 400.

[0090] To save energy, after step S3, the dehumidification method further includes the following steps:

[0091] S4, the sensor continuously detects the humidity and / or moisture content within the dust collection chamber 100; and

[0092] S5, when the temperature and / or humidity in the dust collection chamber 100 are lower than the preset value, the exhaust fan 400 is turned off.

[0093] This dehumidification method can not only avoid the continuous operation of the exhaust fan assembly 400, thus saving energy, but also help to extend the service life of the exhaust fan assembly 400, thereby extending the service life of the dehumidification device.

[0094] Note that the foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
