In a particular embodiment, the present embodiment provides an automatic hand washing machine, in particular, which mainly comprises a hand drying device 2 and two hand washing devices 1.

Wherein the rear side of the hand drying device 2 is provided with a hand drying opening 25 to enable drying of both hands entering into the hand drying opening 25. Specific drying methods are various, and a drying method which does not injure hands is mainly selected. Specifically, the hand drying device can be a hot air blowing device for drying hands by blowing hot air, and the hand drying device can also be a water absorbing device for absorbing water on the surfaces of the hands to achieve a drying effect. It is emphasized that, among other things, to ensure that the hands can be dried, the hand drying apparatus 2 should have a space large enough to accommodate the hands. It should be noted that, in this context, forward refers to the hand tip orientation.

The two hand washing devices 1 are respectively arranged at the left side and the right side of the hand drying device 2, and the back sides of the two hand washing devices are respectively provided with a hand washing opening for respectively brushing the left hand and the right hand, namely, the hand washing device 1 positioned at the left side of the hand drying device 2 is a left hand washing device for brushing the left hand, and the hand washing device 1 positioned at the right side of the hand drying device 2 is a right hand washing device for brushing the right hand. Wherein the hand washing opening and the hand drying opening 25 are preferably provided with a closing door which can be opened and closed.

The hand washing device 1 mainly comprises a brushing part, a brushing driving device for driving the brushing part to brush and a water supply device for supplying water to hands, hands coated with the hand sanitizer enter a hand washing opening, the brushing driving device drives the brushing part to brush the hands of a human body at the moment, and the water supply device supplies water according to needs in the whole brushing process so as to jointly complete the cleaning of the hands. It should be noted that, the brushing driving device, specifically how to drive the hand for cleaning, may be set as required. Such as by reciprocating the brush member laterally along a predetermined path to create a brushing effect.

In the automatic hand washer, when in use, left and right hands respectively enter the corresponding hand washing devices 1 through the hand washing openings on the left and right sides of the hand drying device 2, the left and right hands are respectively cleaned after the hand washing devices 1 are started, at the moment, the brushing driving device drives the brushing piece to complete the brushing operation, and the water supply device supplies water correspondingly. After the hand washing by the hand washing device 1 is completed, the left and right hands are pulled out and put into the hand drying device 2, and both hands are dried. Thereby completing the cleaning operation. In the automatic hand washer, when washing hands, the hands are naturally separated to enter the hand washing devices 1 on the two sides respectively for washing hands, and the cleaning effect can be ensured by washing hands respectively. After hand washing is completed, the two hands naturally draw close to enter from the middle hand drying opening 25 for hand drying, and the requirement on the degree of hand drying is generally not very high, and only large water drops of the hands need to be removed, so that the requirement can be met by drying the two hands simultaneously. Through the arrangement, automatic hand washing and drying can be realized, the operation is convenient and smooth, and the human body habit is met. In summary, the automatic hand washer can effectively solve the problem of inconvenient hand washing operation in the prior art.

The hand washing apparatus 1 may take a variety of forms, such as one in which the brush face of the brushing member may be an internal tube face to enable brushing by rotation, but the brushing effect is poor. Based on this, the brushing member is preferably a brush plate 12, two brush plates 12 are arranged in parallel up and down, the brush surfaces are arranged oppositely, the brushing driving device is used for driving the brush plates 12 to reciprocate back and forth relative to the hand washing box body 11, and the hand washing device 1 further comprises a brushing lifting device 18 for driving the two brush plates 12 to move up and down relatively.

It should be noted that the activation of the water supply device and the activation of the lifting device 18 may be started synchronously, or the former may be started first, and the latter may be started after a first predetermined time interval, such as 3-5 seconds. After the water supply device is started, the operation time length can also be set according to needs, for example, the water supply can be stopped after the lifting device 18 is started in place, or the water supply can be stopped after the operation is carried out for a second preset time length, for example, after 3-5 seconds.

Step 2: the liquid supply device is controlled to supply liquid, and then the brushing driving device is controlled to drive the two brush plates 12 to move back and forth so as to brush for a preset time. It should be noted that the liquid supply time of the liquid supply device can be set as required, and only a single liquid supply amount is needed to clean the hand, and no waste is caused. In particular, the brushing drive device is driven for a third predetermined time period, and the third predetermined time period can be set as required, and is generally between 10 and 15 seconds.

And step 3: the water supply device is controlled to supply water for a predetermined period of time to clean the hands, remove hand cleaning liquid, and the lifting device 18 is controlled to drive the two brush plates 12 to move away from each other to release the hands. When the water supply device starts supplying water, the brushing drive device may still be controlled to drive the two brush plates 12 to move back and forth so as to brush the hand. Wherein the water supply device and the lifting device 18 can be started synchronously, or the water supply device and the lifting device are started firstly, and the lifting device are started after a fourth preset time interval, such as 3-5 seconds. After the water supply device is started, the operation time length can also be set according to needs, for example, the water supply can be stopped after the lifting device 18 is started in place, or the water supply can be stopped after the operation is carried out for a fifth preset time length, for example, after 3-5 seconds.
