The ground processing system increases the cleaning efficiency of the base for clearing the dust granule inside the dust collecting unit (102) of the ground processing device (100).

Description

Ground treatment system and method for cleaning and emptying the same

Technical field

The present invention relates to a floor treatment system and a method of cleaning and emptying the same. Background technique

With the advancement of the times and the rapid development of technology, smart devices such as robots have become well-known products. Not only that, intelligent cleaning machines, intelligent mopping machines and other similar home service robots, which are easy to clean, save time and effort, make people get rid of the cumbersome housework and step into the family life of ordinary people.

The intelligent sweeping machine currently on the market is equipped with a rechargeable battery and a vacuum cleaning unit. The rechargeable battery provides power to the intelligent cleaning machine. The cleaning and cleaning unit cleans and maintains the ground. The dust and other impurities collected from the ground and stored in the dust box are stored in the dust box built in the cleaning machine. Remove the dust box from the sweeper and remove the impurities from the dust box. In order to facilitate the cleaning function to remove the dust under the furniture such as ordinary sofa or bed, and improve the ground coverage of the intelligent cleaning machine, the cleaning machine is generally designed to be very compact, so that the dust box inside the intelligent cleaning machine is correspondingly smaller. This means that the overall volume of impurities such as dust particles is reduced. In order to prevent the dust box from being full, the user often needs to remove the garbage in the dust box, which brings different degrees of burden to the user; at the same time, the particle impurities in the dust box are frequently emptied artificially, and the entire intelligent cleaning machine cannot be truly embodied. Autonomous, uninterrupted ability.

An intelligent sweeper is currently on the market, with a built-in rechargeable battery, cleaning unit and dust box. A charging stand for use with the sweeper provides power to the rechargeable battery. Under the energy supply of the rechargeable battery, the cleaning machine treats the ground, and impurities such as particles that are swept out are stored in the dust box. When the charge of the rechargeable battery in the sweeper is lower than the preset value, the sweeper will automatically switch from the sweep mode to the charge mode and charge back to the charging stand. The charging stand not only has the function of supplying electric energy to the rechargeable battery, but also has a dust collecting unit and a dust collecting cylinder inside. When the cleaning machine returns to the charging stand, and the charging electrode of the cleaning machine and the docking electrode of the charging stand are successfully docked successfully, the roller of the cleaning machine starts to rotate, so that the air inlet passage of the cleaning machine is not blocked by the roller brush. At the same time, the dust collecting unit in the charging base is powered on, and under the action of suction, the debris in the cleaning dust box enters the dust collecting unit from the air inlet passage of the cleaning machine through the air passage of the charging seat. Since the charging stand is not limited by conditions such as cleaning work, the capacity of the dust collecting cylinder built in the charging stand is much larger than that of the dust box of the cleaning machine. Therefore, while the cleaning machine returns to the charging stand, the debris in the cleaning dust box is transferred to the dust collecting cylinder of the charging stand through the dust collecting unit built in the charging stand, and the user only needs to empty the charging stand occasionally. The dust collector can be used, thus eliminating the user Always empty the negative load of cleaning the dust box. However, when the cleaning machine returns to the charging stand for charging and sucking, the rotating direction and the rotating speed of the cleaning brush are the same as the rotating direction and the rotating speed of the cleaning brush when the cleaning machine is in normal working cleaning. This causes a problem: under the suction of the built-in vacuum unit of the charging stand, after the dust sucked from the cleaning dust box enters the air inlet passage of the cleaning machine, part of the dust may be brought back under the rotation of the roller brush. It goes into the dust box of the cleaning machine, so that it cannot enter the air passage of the charging stand and is sucked into the dust collecting unit of the charging stand. As a result, the cleaning unit of the charging stand is not very efficient in cleaning the dust box.

In addition, conventional vacuum cleaners, such as: vertical cyclone cleaners and stick (stick type) small vacuum cleaners, are designed to be compact and compact as large as possible for the operator's convenience and flexibility. As a result, the capacity of the dust collecting device in the vacuum cleaner is affected, and the operator needs to frequently clean the dirt in the dust collecting device, causing different degrees of burden to the operator.

The ground processing device 100 further includes a rechargeable battery (not shown) and an electrode 106. A charging unit (not shown) is disposed on the base 200, and the charging unit is provided with a charging electrode 205. When the surface treatment device satisfies the ash discharge condition, the ground treatment device 100 shifts from the cleaning mode to the pedestal mode.

The ash discharge condition is satisfied, and the threshold value of the rechargeable battery may be set in advance. When the electric quantity of the rechargeable battery is lower than a preset threshold, the ground processing device 100 shifts from the cleaning mode to the search for the pedestal mode, and the first control unit controls the walking unit 107 to work, Said The ground processing device 100 automatically searches for the susceptor 200 such that the electrode 106 of the rechargeable battery is reliably docked with the charging electrode 205 of the charging unit. After the docking is successful, the ground processing device shifts from the pedestal mode to the charging mode. In order to facilitate cleaning and diversification of applications, the cleaning unit 201 of the susceptor 200 is detachably mounted on the charging unit of the susceptor 200. Both the cleaning unit 201 and the charging unit of the susceptor can be used as a functional unit independently with the ground processing apparatus 100.

In order to improve the cleaning efficiency, the ground treatment device 100 further includes a cleaning vacuum source (not shown), the first control unit controls the cleaning vacuum source to work; and in the vacuum state, the cleaning vacuum source Dirt on the ground is entered from the ash inlet 103 and collected into the dust collection unit 102 along the ash passage 104.

In order to facilitate cleaning, the dust collecting chamber 203 of the cleaning unit 201 is located below the ash discharge vacuum source 204.

The dirt cleaning and emptying of the ground treatment system provided by the present invention can be performed by various control modes. In general, the ground treatment device cleans the dirt on the ground in the sweep mode, and switches to the pedestal mode when the ash discharge conditions are met or when charging is required. When the ground handling device finds the pedestal, the two interface and/or the docking between the electrodes. The signals successfully connected by the two can be the switching signals sent by the switches arranged on the interfaces of the two, the electrode signals whose electrodes are successfully docked to detect the change of current or voltage, or the dirt clearing operations respectively set on the ground processing device by manual control. An operational signal from the interface and/or the work control interface disposed on the pedestal cleaning unit. Whether it is a switching signal, an electrode signal, or an operation signal, it can be directly detected or received by the first control unit, and is uniformly controlled by the ground processing device and the ash vacuum source of the pedestal; The second control unit respectively detects or receives, and implements the first control unit to the ground processing device, and the second control unit controls the separate control of the ash vacuum source in the pedestal. In this way, the ash discharge and charging can be carried out simultaneously or separately according to different needs.

In the following, only one working process of the ground processing system provided by the present invention will be described in detail, and the working mode transition brought by other control methods will be referred to the following description.

As shown in Figure 2, in the sweep mode, the rechargeable battery acts as an energy source for the ground handling device 100, providing energy to the travel unit 107, the roller brush 105, and the sweep vacuum source. Through the energy supply of the rechargeable battery, the walking unit 107 drives the ground processing device 100 to move on the surface to be worked; at the same time, the vacuum source is cleaned for vacuum suction, and the roller 105 rotates, and the rotation direction of the roller 105 at this time. It is clockwise so that dust particles on the surface to be worked are collected into the dust collection unit 102. The working function of the ground processing device in the cleaning mode belongs to the prior art, and will not be described herein.

When the amount of the rechargeable battery is lower than a preset value, the ground processing device 100 shifts from the cleaning mode to the search Pedestal mode. Accordingly, the ground processing device 100 autonomously searches for the susceptor 200. The method for the ground processing device 100 to find the susceptor 200 and the control device and the control method for the ground processing device to find the susceptor 200 are all prior art, and are no longer Narration. After the ground processing device 100 finds the susceptor 200, the electrodes of the ground processing device collide with the charging electrodes of the pedestal, and the control unit of the ground processing device determines the charging electrodes of the pedestal by detecting the voltage on the electrodes of the ground processing device. Whether the electrodes of the ground treatment device are docked successfully. If the docking is successful, the first control unit of the ground processing device controls the rotation of the roller brush 105 according to the detected signal, and the direction of rotation of the roller brush 105 changes, which is completely opposite to the previous direction of rotation, and becomes a counterclockwise direction. It should be noted that, when the docking is successful and the steering of the roller brush 105 is changed, the rotation speed of the roller brush 105 is not limited. The rotation speed of the roller brush can be kept constant, or the rotation speed can be increased or decreased, and the dust removal effect of the base 200 on the ground treatment device 100 is not affected. At this time, the rotation of the roller brush 105 includes continuous rotation or intermittent rotation.

The electrode 205 of the charging unit of the susceptor 200 is two reeding reeds. When the electrode 205 on the charging unit is pressed back by the charging electrode 106 of the ground processing apparatus 100, the reed portion located in the pedestal 200 is The contacts in the susceptor 200 are in contact, causing the reeds to be charged, and the power is delivered to the surface treatment apparatus 100 by the reeds. When the second control unit in the base 200 detects that the reed is energized, a signal is output through which the second control unit in the base 200 controls the ash vacuum source 204 in the susceptor 200 to operate. Due to the counterclockwise continuous rotation of the roller brush 105, the air inlet passage 104 and the ash inlet port 103 of the floor treatment device 100 are not blocked by the roller brush 105. Under the vacuum suction of the ash vacuum source 204 in the susceptor 200, the dust particles of the dust collecting unit 102 in the ground processing device 100 enter the ash passage 104 of the ground processing device 100, and are driven by the roller 105. It is easily passed through the dust suction passage 300 from the ash inlet 202 of the susceptor 200 to the dust collecting chamber 203 of the cleaning unit 201 of the susceptor 200.

When the cleaning unit 201 and the charging unit are integrally formed and are not detachably disposed, after the ground processing device 100 successfully docks with the charging unit of the susceptor 200, the ash discharge vacuum source in the cleaning unit is controlled by the second control unit on the susceptor 200. 204 work. At this time, the second control unit may be disposed in the cleaning unit 201 or may be disposed in the charging unit.

The cleaning unit 201 of the base 200 is detachably coupled to the base for ease of operation and product versatility.

200 on the charging unit. A dust suction passage 300 is externally connected to the ash inlet 202 of the cleaning unit 201 of the susceptor 200. Both ends of the dust suction passage 300 are respectively connected to the ash inlet 103 of the floor treatment device 100 and the ash inlet 202 of the susceptor 200. When the susceptor 200 is simultaneously used to dock the ground processing apparatus 100 for charging and emptying the dust particles inside the ground processing apparatus 100, the cleaning unit 201 and the charging unit are integrated. When the user needs to use the cleaning unit 201 as a separate vacuum cleaner, the connection of the cleaning unit 201 to the dust suction passage 300 is disconnected, A hose is connected to one end of the ash port 202 of the cleaning unit 201, and the other end of the hose is connected with a dust attachment, such as a roller brush, a flat suction, etc., and can be used alone. At this time, the second control unit that controls the operation of the ash vacuum source of the cleaning unit is located in the cleaning unit 201, and the control subunit for controlling the charging of the charging unit is separately disposed in the charging unit of the susceptor.

In order to make the user touch the dust particles as little as possible when emptying the dust collecting chamber. In the dust collecting chamber of the base 200 cleaning unit, a dust collecting bag matching the shape of the inner cavity of the dust collecting chamber can be placed. When the cleaning unit has been working for a long time, when there are enough dust particles in the built-in dust bag, open the dust collecting chamber of the cleaning unit and take out the dust bag directly. To prevent dust from spreading, a string can also be provided on the dust bag. The upper opening of the dust bag can be tightened by a tether before the dust bag is taken out.

Further, in the cleaning unit 201 of the susceptor 200, it is preferable that the dust collecting chamber 203 is located below the ash evacuation vacuum source 204.
