Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a washing machine and a washing method for washing tableware, fruits and vegetables. Background Art

[0002] As a common household appliance, dishwashers are increasingly used in our lives.

[0003] Dishwashers are generally equipped with a detergent dispenser for storing a certain amount of detergent and automatically distributing the amount of detergent. Most existing detergent dispensers are installed on the door of the dishwasher, and are generally driven by a motor to drive the impeller to rotate to distribute the detergent. In specific applications, the following shortcomings are generally present: (1) Due to the limitation of the door space, the size of the detergent dispenser can only be designed to be small, so that the volume of the detergent dispenser for storing detergent is small, so that the user needs to frequently add detergent to the detergent dispenser during the use of the dishwasher, which makes the operation of the user more cumbersome during the use of the dishwasher; (2) The motor drive structure is costly, and the noise generated during the rotation of the impeller is relatively loud, which seriously affects the user experience. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a cleaning machine capable of dispensing detergent by means of a door opening and closing action, with a dispensing mechanism having a simple structure and low cost, and capable of solving the transmission noise problem, in view of the current status of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a cleaning method for the above-mentioned cleaning machine in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve at least one of the above technical problems is:

[0007] A washing machine comprises a box body with a washing chamber, the front side of the box body is provided with an opening and a door body capable of opening and closing the opening, the side wall of the door body is provided with a hinge rotatably connected to the side wall of the box body near the lower end, and further comprises:

[0008] A liquid storage tank, disposed under the box body, for storing detergent;

[0009] The damping member is arranged under the side wall of the box body, and its rear end is rotatably connected to the rear side of the liquid storage tank, and its front end is connected to the hinge. The damping member forms a piston structure that can pump detergent in the liquid storage tank when the door is opened and closed. The input end of the piston structure is connected to the liquid storage tank, and the output end is connected to the washing chamber.

[0010] The present invention utilizes hinges and damping members on the side of the door body to form a structure that can pump detergent in the liquid storage tank when the door is opened and closed. The piston structure formed by the damping member can pump the detergent into the washing chamber. This structure not only does not require the provision of a separate driving mechanism and transmission mechanism, but also has a simple and reasonable structure and low cost, and eliminates the noise problem generated by the operation of the driving mechanism. At the same time, the pumping pressure generated in the process of conveying detergent can produce a damping effect on the door body, and there is no need to provide a separate door body damping structure, which further simplifies the structure of the cleaning machine and reduces production costs.

[0011] Preferably, the damping member includes a sleeve, a piston rod and a piston sheet, the sleeve is hollow inside to form a pump cavity for pumping detergent, at least the rear portion of the piston rod is reciprocatingly disposed in the pump cavity, and the piston sheet is disposed in the pump cavity and cooperates with the piston rod to pump detergent. The above structure is convenient for forming a piston structure capable of pumping detergent, while providing damping for the door body, and the structure is simple, compact, and easy to operate.

[0012] Preferably, the sleeve has a closed rear end and an opening at the front end, the piston rod is arranged in the sleeve so as to be reciprocatingly movable along the axial direction of the sleeve, and the front end of the piston rod passes through the opening and is connected to the hinge. This structure facilitates the matching connection between the sleeve and the piston rod.

[0013] Preferably, the sleeve side wall has an input end near the rear end, and the sleeve side wall has an output end near the front end. The low input and high input structure can prevent liquid leakage.

[0014] Preferably, the piston sheet is connected to the rear end of the piston rod and has a conical cross section with the tip facing backwards, and the edge of the piston sheet contacts and frictionally fits with the inner wall of the sleeve. This structure facilitates pumping the detergent at the rear of the pump chamber into the front of the pump chamber.

[0015] Preferably, the liquid storage box is provided with a liquid outlet at the bottom of the side wall facing the damping element, and the liquid outlet is connected to the input end of the sleeve through a first conduit. The above structure is adopted to facilitate the delivery of detergent into the sleeve.

[0016] Preferably, the side of the box body is provided with an air inlet, and the outer side of the box body is provided with a hot air component that can heat the external air and then input it into the washing chamber through the air inlet, the lower end of the shell of the hot air component is connected to the air inlet, the lower end of the shell of the hot air component is bent to one side to form a detergent temporary storage area connected to the air inlet, and the output end of the sleeve is connected to the temporary storage area through a second conduit. A solenoid valve can be further provided in the above-mentioned temporary storage area to control whether the temporary storage area is connected to the air inlet, to ensure that liquid is added before the washing program is started, and to avoid adding liquid when hot air drying or non-washing is required.

[0017] Preferably, the temporary storage area extends laterally on one side of the air inlet, and the lower edge of the air inlet is lower than the bottom edge of the temporary storage area, and the bottom of the temporary storage area is connected to the second conduit. Preferably, a liquid return port is provided at the top of the liquid storage tank, and a liquid return pipe connected to the liquid return port is provided near the top of the temporary storage area. The above structure is adopted to ensure that when the temporary storage area is connected to the air inlet, the detergent can be delivered to the washing chamber as quickly as possible, and when the temporary storage area is isolated from the air inlet, the excess detergent is sent back to the liquid storage tank to avoid leakage due to the temporary storage area exceeding the capacity.

[0018] A cleaning method for a cleaning machine, using the above cleaning machine, the cleaning method is:

[0019] In the initial state, the damping element is filled with detergent;

[0020] When the door of the washing machine is opened, the door body opens, driving the hinge to flip forward, and the damping member linked with the hinge gradually stretches. During the stretching process of the damping member, its piston structure pumps the detergent inside into the washing chamber of the washing machine, and at the same time, the detergent in the liquid storage tank is replenished into the damping member; during the above-mentioned pumping process, the damping member uses the pressure of the pumping process to provide damping for the door body;

[0021] When the door is closed, the hinge flips backwards driven by the door body, and the damping member linked to the hinge gradually retracts. During the retraction process of the damping member, its piston structure transfers the detergent from the rear area to the front area, preparing for the detergent delivery when the door is opened next time.

[0022] After closing the door, start the washing process.
