Description

Sweeping robot base station Technical Field The present invention relates to a base station of a floor sweeping robot, and more particularly, to a base station of a floor sweeping robot which is built-in to collect dust in a dust tub of the floor sweeping robot, wash rags of the floor sweeping robot, and dry the rags if the floor sweeping robot is combined. Background In recent years, with the development of industrial technology, a sweeping robot that automatically travels in an area to be swept without requiring a user operation and sweeps is being developed. Such a floor sweeping robot has a sensor capable of recognizing a space to be cleaned, an agitator capable of cleaning the floor, a cloth capable of wiping the floor, and the like, sucks dust on the floor in the space recognized by the sensor, and travels while wiping the floor with the cloth. Among the floor sweeping robots are a dry floor sweeping robot capable of removing foreign matters scattered on the floor by suction and a wet floor sweeping robot capable of effectively removing foreign matters attached to the floor by wiping the floor with a cloth containing moisture. The dry type floor sweeping robot has a dust tub, and sucks foreign materials on the floor by suction force of a suction motor. The wet type floor sweeping robot has a water bucket configured to effectively remove foreign matter adhering to the floor by supplying water accommodated in the water bucket to the cloth and wiping the cloth to the floor in a state of containing water. In addition, there are also sweeping robots having both the form of agitators and the form of wipes. The charging seat of the sweeping robot is a device for docking the sweeping robot for completing sweeping and supplying power to a battery arranged on the sweeping robot to charge the battery. The inside of charging seat is provided with power module. The charging seat is provided with a charging terminal connected with the power supply module, and the sweeping robot is provided with a corresponding terminal. In the case where the charging terminal is in contact with the counterpart terminal, charging is performed by supplying power to the battery. On the other hand, when the robot cleaner is disposed in a room of a building, a certain range of the indoor space is occupied. In this case, the indoor space efficiency may be deteriorated. In addition, when the user or the pet passes by, problems may occur in that the user or the pet is injured due to collision with the robot cleaner, and the robot cleaner is damaged. In addition, in the case of a base station to which a dust collecting function of the floor sweeping robot is added, there is a limit in that interior decoration may be damaged as the occupied volume becomes large. On the other hand, chinese patent application No. CN218922468U discloses a base station for a cleaner located at the lower side of a washing machine, a cleaning robot is combined with the base station to charge and collect dust, and wet wipes of the cleaning robot are washed. However, in the above-mentioned base station for a cleaner, an open space into which the robot for cleaning floor can enter is formed at the lower side of the washing machine, a detergent and water supply device for washing wet cloth are provided at the upper vertical side of the space into which the robot for cleaning floor enters, and a dust bag is disposed at the side of the space into which the robot for cleaning floor enters. In such an arrangement, the overall height of the cleaner base station is increased, and there is a limitation in that installation cannot be performed using a lower space of furniture including the washing tub. In addition, since the above-described cleaner base station needs to be provided at the lower side of the washing machine, it is necessary to have a space for providing the washing machine, and there is a limitation in that it is necessary to provide a space for providing a space exceeding the height of the washing machine itself in consideration of the height of the cleaner base station. In addition, since the space for combining the dust bag is close to the ground, the user needs to kneel down or crouch down before the base station in order to combine the dust bag, and the space for combining the dust bag is also narrow, so that the user needs to stretch into the base station by hand. In addition, foreign materials attached to the cloth may be contained in the contaminated water during the washing of the cloth by the robot. At this time, when sewage is sucked into or discharged from the sewage tank, a portion of foreign matter not filtered by the filter passes through the centrifugal pump, and if it is used for a long period of time, there is a risk that foreign matter accumulates inside the pump to cause clogging thereof. In addition, chinese patent No. CN218279511U discloses a point where a negative or positive pressure is created by a pump to move a fluid. The above base s
