[0040] like Figures 1 to 5As shown, the cleaning machine of this embodiment includes a housing 1, a door body 2 and a door hinge assembly 3. The housing 1 has an open chamber. Specifically, the housing 1 includes a box body 11 and a base 12 located under the box body 11. The chamber is located in the box body 11, and the front side of the chamber has an opening. The door body 2 and the box body 11 are arranged along the front-to-back direction. The door body 2 is rotatably arranged at the opening of the housing 1 to open and close the opening.

[0041] like Figure 2 and Figure 3 As shown, the door hinge assembly 3 is used to realize the rotation connection between the door body 2 and the housing 1. There are two groups of the door hinge assemblies 3, which are arranged at intervals along the left and right directions. The door hinge assembly 3 located on the left is installed on the left wall of the base 12, and the door hinge assembly 3 located on the right is located on the right wall of the base 12. The structures of the two groups of door hinge assemblies 3 are the same, and the door hinge assembly 3 located on the right is taken as an example for description below.

[0042] like Figure 3 As shown, the door hinge assembly 3 includes a door hinge 31, a pull rope 32 and a control assembly. The control assembly is arranged on the side of the door body 2 and is connected to the door hinge assembly 3. It is connected to the controller electrical signal to control the door opening or closing action by turning on and off the power.

[0043] like Figure 1 , 5 As shown, this embodiment also provides a left and right waving sensor component 4, which is arranged at the top edge of the housing 1 and is connected to the controller electrical signal to trigger the power on and off state of the control component through a waving action.

[0044] The control assembly includes a guide rail 33, a first connecting member 36, a second connecting member and a magnetic body 39. The door hinge 31 is rotatably arranged at the lower position of the housing 1, and the rotation axis of the door hinge 31 extends along the left-right direction. The guide rail 33 is arranged outside the chamber, and extends along the arrangement direction of the door body 2 and the housing 1 (i.e., extends along the front-back direction), and is relatively fixed to the base 12 of the housing 1.

[0045] like Figure 3As shown, the first connecting member 36 and the second connecting member are arranged at intervals along the length direction of the guide rail 33 (i.e., arranged at intervals along the front-to-back direction), and one of the first connecting member 36 and the second connecting member is an electromagnet, and the other is a magnetic conductive member or a magnetic member. Specifically, the first connecting member 36 is arranged on the base 12 of the housing 1, away from the door body 2, and is a magnet. The second connecting member is arranged adjacent to the door body 2, that is, the second connecting member is located in front of the first connecting member 36. The aforementioned second connecting member is connected to the second end of the pull rope 32, and is magnetically attracted or magnetically repelled with the first connecting member, so that it can move relative to the guide rail 33 along the length direction of the guide rail 33, that is, along the front-to-back direction. In this embodiment, the second connecting member is a sliding member 34 that is slidably matched with the guide rail 33, and the sliding member 34 is an electromagnet. In addition, a magnetic body 39 is arranged on the outer side wall of the base 12 of the housing 1, and the magnetic body 39 is arranged on the same side as the first connecting member 36, and has the same magnetic pole as the first connecting member 36, and the electromagnet is located between the magnetic body 39 and the first connecting member 36.

[0046] When the electromagnet is energized, it is attracted to the first connecting member 36 and repelled from the magnetic body 39, so that the electromagnet moves backward relative to the guide rail 33 to drive the second end of the pull rope 32 to move backward, thereby realizing the opening of the door body 2; when the electromagnet is de-energized, it repels from the first connecting member 36 and is attracted to the magnetic body 39, so that the electromagnet moves forward relative to the guide rail 33 to drive the second end of the pull rope 32 to move forward, thereby realizing the closing of the door body 2.

[0047] In order to prevent the sliding member 34 from moving backward out of the guide rail 33 , a limiting member (not shown) is provided at the rear end of the guide rail 33 to limit the sliding member 34 from moving backward and then leaving the guide rail 33 , and the limiting member is located on the moving path of the sliding member 34 .

In this embodiment, the second end of the pull rope 32 is connected to the sliding member 34 through a connecting rod 35, and the connecting rod 35 extends along the front-back direction, and the front and rear ends are respectively connected to the pull rope 32 and the sliding member 34. In addition, the portion of the pull rope 32 located between the second roller 38 and the first roller 37 is the upper section 321 of the pull rope, and the portion of the pull rope 32 located between the guide rail 33 and the first roller 37 is the lower section 322 of the pull rope. The upper section 321 of the pull rope and the lower section 322 of the pull rope are both arranged along the front-to-back direction and are parallel to each other.

[0049] In this embodiment, if Figure 1 , 4 As shown in Figures 5 and 6, the left and right hand waving sensing assembly 4 includes a first limit arm 41, a second limit arm 42, a limit frame 43 and a driving member 44. The first limit arm 41 and the second limit arm 42 are vertically arranged at the top edge of the door body 2 and are spaced apart from each other. The limit frame 43 is movably disposed at the top of the casing 1. In the door closing state, the limit frame 43 is movably disposed between the first limit arm 41 and the second limit arm 42. A left and right hand waving sensor 45 is provided at the top front edge of the limit frame 43. The driving member 44 is used to drive the limit frame 43 to move left and right and is connected to the controller electrical signal 45.

[0050] A first limit block 431 extending outward is provided on the left edge of the limit frame 43, and accordingly, a first limit opening 411 is formed on the first limit arm 41, which can cooperate with the first limit block 431 for limiting when the limit frame 43 moves to the left to the end of the stroke; a second limit block 432 extending outward is provided on the right edge of the limit frame 43, and accordingly, a second limit opening 421 is formed on the second limit arm 42, which can cooperate with the second limit block 432 for limiting when the limit frame 43 moves to the right to the end of the stroke.

[0051] The top of the first limiting arm 41 is also provided with a buckle (not shown in the figure) which can elastically lock the first limiting block 431 when the first limiting block 431 is plugged into the first limiting opening 411, and the upper surface of the first limiting block 431 is provided with a pit 4311 for the buckle to be locked therein.

[0052] The driving member 44 is a motor, which is arranged at the top of the casing 1 and at the rear side of the limit frame 43. The output shaft of the motor extends forward and is connected to a driving wheel 46. The driving wheel 46 has three sets of lever arms 461 extending radially. The inner side wall of the top of the limit frame 43 is provided with a first notch groove 401 extending from the left end to the right, and the inner side wall of the bottom of the limit frame 43 is provided with a second notch groove 402 extending from the right to the left. The ends of the lever arm 461 cooperate with the first notch groove 401 and the second notch groove 402 for transmission.

[0053] The door opening and closing method of the cleaning machine in this embodiment:

[0054] When the limit frame 43 is located at the rightmost position, the door is in a normal closed state;

[0055] When the door needs to be opened, the hand is waved to the left, and the driving member 44 drives the limit frame 43 to move to the middle position between the first limit arm 41 and the second limit arm 42. At this time, the control component is triggered, and the electromagnet is energized, and it attracts the first connecting member and repels the magnetic body, so that the electromagnet moves backward relative to the guide rail to drive the second end of the pull rope to move backward, and then the door body is opened;

[0056] After putting the tableware, wave your hand to the right again, slowly pull the door back through the hinge system, and move the limit frame to the right until the limit frame is at the rightmost position to complete the door closing action; or, if after putting the tableware, you need to prevent children from accidentally touching the door while cleaning, wave your hand to the left, slowly pull the door back through the hinge system, and move the limit frame to the left until the limit frame is at the leftmost position to achieve door closing while the buckle limits the limit frame. After cleaning is completed, manually cancel the limit of the buckle and the limit frame, and then wave your hand to the right to open the door.

[0057] This embodiment combines a control component with a left and right waving sensor component. When the door needs to be opened, wave your hand to the left, and the left and right waving sensor component transmits the detected signal to the controller. The controller triggers the control component to open the door. After putting the tableware, wave your hand to the right, and the left and right waving sensor component transmits the detected signal to the controller. The controller triggers the control component and slowly pulls the door back through the hinge system until the door is closed. The entire door opening and closing process does not require the use of a tension spring, thus avoiding the failure of the tension spring used in the background technology and the subsequent impact on the opening and closing of the door. The reliability is high, and the entire process does not require manual pushing and pulling, which is more labor-saving.
