With the increasing living standard of people, the dish washing machine is used as a kitchen household appliance and is more and more introduced into families. The dish-washing machines on the market at present are generally divided into a table type dish-washing machine, a cabinet type dish-washing machine and a trough type dish-washing machine, wherein the table type dish-washing machine is an integral independent structure and is generally placed on a table top for use; the cabinet type dish washing machine is also an independent structure, but needs to be embedded into a kitchen cabinet for use; the sink dishwasher is combined with a sink and is generally installed in a kitchen cabinet for use.

Currently, the door structure of a cleaning machine has a single function, for example, in the structure disclosed in chinese patent application CN108056732A, water tank type cleaning machine (application No. CN201710939807.5), the cleaning machine has a water tank body with a washing space and an open top, a top movably disposed on the water tank body, and a cover plate capable of opening or closing relative to the open top of the water tank body. Because in the cleaning process, can produce the higher steam of temperature, consequently, in the cleaning process, the door body pins for basin body, after the washing finishes, because reasons such as vapor condensation lead to this internal negative pressure of basin easily in the basin body, and lead to the door body to be difficult to open, this ejector pin that just needs to set up and to open the door body, among the prior art, this ejector pin and lock separately arrange and drive through different actuating mechanism, make cleaning machine overall structure loaded down with trivial details, it is with high costs.

Disclosure of Invention

The invention aims to solve the technical problem of the prior art, and provides a cleaning machine which can realize whether a door body is locked or not and whether the door body is pushed open or not through the same driving mechanism and can be automatically opened and closed.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a door physical stamina automatic switch's cleaning machine, includes the basin body and rotates to be connected in the door body at this basin body top edge, and the outside extension in at least one edge of this door body is formed with the outer extension district of corresponding basin body lateral wall, its characterized in that: also comprises

The driving piece is arranged on the outer side wall of the water tank body, and a first gear is connected to the power output end of the driving piece;

the second gear is rotatably arranged on the outer side wall of the water tank body and is in meshing transmission with the first gear;

the connecting piece is arranged on the second gear and synchronously rotates along with the second gear, and a first connecting arm and a second connecting arm which are arranged at intervals and extend outwards are arranged at the edge of the connecting piece;

the first end of the first connecting rod is rotatably connected to the first connecting arm;

the top rod is arranged on the outer side wall of the water tank body in a vertically movable mode, the first end of the top rod is rotatably connected with the first end of the first connecting rod, and the second end of the top rod extends towards the door body;

the first end of the second connecting rod is rotatably connected with the second connecting arm;

the first end of the third connecting rod is rotatably connected with the second end of the second connecting rod, and the second end of the third connecting rod is bent towards one side to form a first hook part;

the upper end of the lock rod is connected to the lower wall surface of the door body extension area, and the lower end of the lock rod is provided with a second hook part which is bent towards one side and can be matched with and hooked tightly with the first hook part; and

and the guide groove is arranged on the outer side wall of the water tank body and is connected with the third connecting rod through a guide pin, so that the first hook part deviates from the second hook part under the upward movement state of the ejector rod, and the first hook part is close to the second hook part under the downward movement state of the ejector rod.

In the above scheme, the guide groove is in an inverted J-shaped structure, a vertical part on the J-shaped structure is arranged between the second gear and the lock rod, a distance is kept between the vertical part and the lock rod in the horizontal direction, and the bending direction of a bent part on the J-shaped structure is the same as that of the second hook part. By adopting the structure, the first hook part can be outwards separated from the second hook part along with the moving track of the third connecting rod in the guide groove in the initial ejection state of the ejector rod, so that the interference between the ejection state and the locking state is avoided, and the use is not influenced.

Preferably, the guide pins are at least two and are arranged at intervals on the back of the third connecting rod, and the guide pins can be slidably connected in the guide grooves. And under the state that the outer end of the first hook and the outer end of the second hook are aligned up and down, one guide pin is positioned in the bent part of the J-shaped structure of the guide groove, and the other guide pin is positioned in the vertical part of the J-shaped structure of the guide groove. The guide pin above the third connecting rod is used for matching with the J-shaped structure of the guide groove, so that the interference between the ejection state and the locking state is avoided, and the guide pin below the third connecting rod enables the third connecting rod to move more smoothly.

Preferably, the guide pin is inserted in the guide groove and is sleeved with a rotating sleeve capable of being matched with the guide groove in a rolling mode. By adopting the structure, the third connecting rod can move more smoothly, and the unlocking and locking actions are more flexible.

In each of the above schemes, the first connecting arm and the second connecting arm are arranged perpendicularly, and the second gear is provided with a first abdicating groove for installing the first connecting arm and a second abdicating groove for installing the second connecting arm. The connecting piece is fixed on the outer side wall of the second gear through the D-shaped column, and the structure is adopted, so that the relative heights between the second gear and the first connecting arm and between the second gear and the second connecting arm are eliminated, and the first connecting arm and the second connecting arm and the corresponding connecting positions of the first connecting rod, the second connecting rod, the third connecting rod, the ejector rod and the lock rod are all located in the same plane.

Preferably, the outer side wall of the sink body is provided with a limiting column capable of limiting the rotating position of the second gear. Under the condition that the ejector rod is completely ejected out and the first hook part and the second hook part are completely separated, the limiting column limits the second gear to continue rotating so as to protect all parts which are matched with each other from being damaged due to overlarge stress.

In order to facilitate installation, a sliding groove which is arranged close to the door body and extends vertically is further formed in the outer side wall of the water tank body, and the ejector rod can be constrained in the sliding groove in a vertically moving mode.

Preferably, the cleaning machine further comprises a mounting box and a transmission gear set, the mounting box is arranged on the outer side wall of the water tank body, the first gear, the second gear, the transmission gear set, the connecting piece, the first connecting rod, the second connecting rod, the third connecting rod, the lower portion of the ejector rod and the lower end of the lock rod are all hidden in the mounting box, and the transmission gear set can be rotatably arranged in the mounting box and connected between the first gear and the second gear. The transmission gear set can play the roles of reducing speed and increasing torque, and the diameter and the number of the gears in the transmission gear set can be adjusted according to actual requirements.

As a scheme for avoiding interference between the ejection state and the locking state, an avoiding groove which can avoid the situation that the first hook part and the second hook part cannot be separated when the ejector rod moves upwards to the limit position is formed in the upward concave lower wall of the extension area. Set up this and dodge the groove, the upward moving distance that has increased the ejector pin in fact just can realize the door body and push away the process, under ejector pin quiescent condition promptly, first hook portion and second hook portion cooperate the locking, when the ejector pin just begins the rebound, the ejector pin upper end is unsettled and not with the door body contact in dodging the groove, nevertheless along with the ejector pin moves up, first hook portion breaks away from each other with second hook portion gradually, when the stroke of ejector pin is greater than the height of dodging the groove and to the door body application of force, first hook portion has broken away from second hook portion completely, therefore, this scheme can successfully avoid ejecting state and locking state to form the interference, realize the interconversion of the ejecting state of the door body and locking state smoothly.

As another scheme for avoiding interference between the ejection state and the locking state, the center of the second gear is O, the center of rotation of the second connecting arm with respect to the first end of the second link is O1, the center of rotation of the second end of the second link with respect to the first end of the third link is O2, the center of rotation of the first connecting arm with respect to the first end of the first link is O3, the center of rotation of the second end of the first link with respect to the ejector pin is O4, the center of the guide pin located at the upper portion of the third link is O5, the center of the upper end of the ejector pin is O6, the distance between O and O1 is a, the distance between O1 and O2 is b, the distance between O and O2 is c, the distance between O2 and O5 is d, the distance between O1 and O5 is e, the distance between O3 and O4 is f, the distance between O and O3 is g, the distance between O3 and O6 and O4 are h, and O6, the distance between O and O4 is j,

when the avoiding groove does not exist, the upper end of the ejector rod can apply force to the door body as soon as the upper end of the ejector rod moves, and the sliding speed of the third connecting rod along the guide groove is required to be larger than the upward moving speed of the ejector rod.

Compared with the prior art, the invention has the advantages that: whether the door body is locked or not and whether the door body is ejected or not can be driven by the same driving mechanism, when the door body is used, the driving piece drives the second gear to transmit positively, the ejector rod is downwards far away from the door body, and the first hook part and the second hook part are gradually close until the first hook part and the second hook part are hooked tightly, so that the locking of the door body is realized; the driving piece drives the second gear to rotate reversely, the first hook part is gradually separated from the second hook part along with the movement trend of the third connecting rod in the guide groove, and meanwhile, the ejector rod gradually moves upwards to push the door body open.
