Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a cleaning machine for cleaning tableware, fruits and vegetables. Background Technology

[0002] As a common household appliance, dishwashers are increasingly being used in daily life.

[0003] Dishwashers are generally equipped with a detergent dispenser for storing a certain amount of detergent and for automatically distributing the detergent. Most existing detergent dispensers are installed on the dishwasher door and are generally driven by a motor to rotate an impeller to distribute the detergent. In practical applications, they generally have the following shortcomings: (1) Due to the limited space in the door, the size of the detergent dispenser can only be designed to be small. This results in a small volume of detergent for storing detergent, which means that users need to frequently add detergent to the dispenser during the use of the dishwasher, making the operation of the dishwasher more cumbersome; (2) The motor drive structure is expensive, and the noise generated during the rotation of the impeller is relatively loud, which seriously affects the user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning machine that can dispense detergent by opening and closing the door, which is based on the current situation of the prior art. The dispensing mechanism has a simple structure, low cost, and can solve the problem of transmission noise.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A washing machine includes a housing with a washing chamber, an opening on the front side of the housing and a door capable of opening and closing the opening, a hinge rotatably connected to the side wall of the housing near the lower end of the door, and further includes:

[0007] A liquid storage tank, located below the main body, is used to store detergent;

[0008] A damping element is located below the side wall of the housing, with its rear end rotatably connected to the rear side of the liquid storage tank and its front end connected to the hinge. The damping element forms a piston structure that can pump detergent from the liquid storage tank when the door is opened or 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.

[0009] This invention utilizes hinges and damping components on the side of the door to form a structure capable of pumping detergent from the storage tank during door opening and closing. The piston structure formed by the damping components pumps the detergent into the washing chamber. This structure eliminates the need for separate drive and transmission mechanisms, resulting in a simple, reasonable, and low-cost design, while also eliminating noise issues caused by the drive mechanism. Furthermore, the pumping pressure generated during detergent delivery provides a damping effect on the door, further simplifying the cleaning machine structure and reducing production costs.

[0010] Preferably, the damping component includes a sleeve, a piston rod, and a piston plate. The sleeve is hollow, forming a pump chamber for pumping detergent. At least the rear portion of the piston rod is reciprocally disposed within the pump chamber. The piston plate is disposed within the pump chamber and cooperates with the piston rod to pump detergent. This structure facilitates the formation of a piston structure capable of pumping detergent while providing damping for the door. The structure is simple, compact, and easy to operate.

[0011] Preferably, the sleeve is closed at the rear end and has an opening at the front end. The piston rod is disposed within the sleeve and is axially movable along the sleeve. The front end of the piston rod passes through the opening and is connected to a hinge. This structure facilitates the mating connection between the sleeve and the piston rod.

[0012] Preferably, the sleeve sidewall has an input end near the rear end and an output end near the front end. This low-input, high-input structure helps prevent liquid leakage.

[0013] Preferably, the piston plate is connected to the rear end of the piston rod and has a tapered cross-section with the tip facing rearward. The edge of the piston plate contacts and frictionally engages with the inner wall of the sleeve. This structure facilitates pumping detergent from the rear of the pump chamber to the front of the pump chamber.

[0014] Preferably, the liquid storage tank has a liquid outlet at the bottom of its side wall facing the damping element, and this liquid outlet is connected to the input end of the sleeve via a first conduit. This structure facilitates the delivery of detergent into the sleeve.

[0015] Preferably, an air inlet is provided on the side of the housing, and a hot air assembly is provided on the outside of the housing to heat the outside air and input it into the washing chamber through the air inlet. The lower end of the housing of the hot air assembly is connected to the air inlet, and the lower end of the housing of the hot air assembly is bent to one side to form a detergent storage area connected to the air inlet. The output end of the sleeve is connected to this storage area through a second conduit. A solenoid valve can also be further provided in the storage area to control whether the storage area is connected to the air inlet, ensuring that detergent is added before the washing program starts, and avoiding adding detergent when hot air drying or when washing is not required.

[0016] Preferably, the temporary storage area extends laterally to 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. The bottom of the temporary storage area is connected to the second conduit. Preferably, a return port is provided at the top of the liquid storage tank, and a return pipe connected to the return port is provided near the top of the temporary storage area. This structure ensures that when the temporary storage area is connected to the air inlet, detergent can be quickly delivered to the washing chamber; and when the temporary storage area is separated from the air inlet, excess detergent is returned to the liquid storage tank to prevent leakage due to the temporary storage area exceeding its capacity.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model utilizes the hinges and damping components on the side of the door to form a structure that can pump detergent from the storage tank during the opening and closing of the door. The piston structure formed by the damping components can pump the detergent into the washing chamber. This structure not only eliminates the need for a separate drive mechanism and transmission mechanism, but also has a simple and reasonable structure, low cost, and eliminates the noise problem caused by the operation of the drive mechanism. At the same time, the pumping pressure generated during the delivery of detergent can produce a damping effect on the door, eliminating the need for a separate door damping structure, further simplifying the structure of the cleaning machine and reducing production costs.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, the cleaning machine of this embodiment includes a housing 1 with a washing chamber. The front of the housing 1 has an opening and a door 2 that can open and close the opening. A base 7 is provided at the bottom of the housing 1, and there is an installation space between the base 7 and the bottom of the housing 1. The installation space 71 can be used to install electrical boxes, etc. A hinge 3 is provided near the lower end of the side wall of the door 2, which is rotatably connected to the side wall of the housing 1.

[0024] The cleaning machine also includes a liquid storage tank 4 and a damping component 5. The liquid storage tank 4 is located in the installation space 71 below the housing 1 and is used to store detergent. The damping component 5 is located below the side wall of the housing 1, with its rear end rotatably connected to the side wall of the base 7 below the rear side of the liquid storage tank 4, and its front end connected to the hinge 3. The damping component 5 forms a piston structure that can pump detergent from the liquid storage tank 4 when the door is opened or closed. The input end of the piston structure is connected to the liquid storage tank 4, and the output end is connected to the washing chamber.

[0025] The above structure utilizes the hinge 3 and damping element 5 on the side of the door 2 to form a structure that can pump detergent from the liquid storage tank 4 during the opening and closing action of the door. The piston structure formed by the damping element 5 can pump the detergent into the washing chamber; at the same time, the pumping pressure generated during the delivery of detergent can produce a damping effect on the door 2.

[0026] The damping component 5 includes a sleeve 51, a piston rod 52, and a piston plate 53. The sleeve 51 is hollow, forming a pump chamber 511 for pumping detergent. At least the rear part of the piston rod 52 is reciprocally movable within the pump chamber 511. The piston plate 53 is located within the pump chamber 511 and cooperates with the piston rod 52 to pump detergent. This structure facilitates the formation of a piston structure capable of pumping detergent while providing damping for the door body 2. The structure is simple, compact, and easy to operate.

[0027] The sleeve 51 is closed at the rear end and has an opening at the front end. The piston rod 52 is disposed in the sleeve 51 and can reciprocate along the axial direction of the sleeve 51. The front end of the piston rod 52 passes through the opening and is connected to the hinge 3. This structure facilitates the mating connection between the sleeve 51 and the piston rod 52.

[0028] The sleeve 51 has an input end near the rear end and an output end near the front end on its side wall. This low-input, high-input structure is designed to prevent liquid leakage.

[0029] The piston plate 53 is connected to the rear end of the piston rod 52 and has a tapered cross-section with the tip facing rearward. The edge of the piston plate 53 contacts and frictionally engages with the inner wall of the sleeve 51. This structure facilitates the pumping of detergent from the rear of the pump chamber 511 to the front of the pump chamber 511.

[0030] The liquid storage tank 4 has a liquid outlet 41 at the bottom of its side wall facing the damping element. This liquid outlet 41 is connected to the input end 501 of the sleeve 51 via the first conduit 10. This structure facilitates the delivery of detergent into the sleeve 51.

[0031] An air inlet 11 is provided on the side of the housing 1. A hot air assembly 6 is provided on the outside of the housing 1, which heats the outside air and introduces it into the washing chamber through the air inlet 11. The lower end of the housing of the hot air assembly 6 is connected to the air inlet 11. The lower end of the housing of the hot air assembly 6 is bent to one side to form a detergent storage area 61 connected to the air inlet 11. The output end 502 of the sleeve 51 is connected to the storage area 61 through the second conduit 30. A solenoid valve 62 can be further provided in the storage area 61 to control whether the storage area 61 is connected to the air inlet 11, ensuring that detergent is added before the washing program starts, and avoiding adding detergent when hot air drying or when there is no washing requirement. The bottom wall of the storage area 61 can be gradually inclined downward towards the air inlet 11. The storage area 61 can be used to store detergent in a measured quantity.

[0032] The temporary storage area 61 extends laterally to one side of the air inlet 11, and the lower edge of the air inlet 11 is lower than the bottom edge of the temporary storage area 61. The bottom of the temporary storage area 61 is connected to the second conduit 30. A return port 42 is provided on the top of the liquid storage tank 4, and a return pipe 20 connected to the return port 42 is provided near the top of the temporary storage area 61. With the above structure, it is ensured that when the temporary storage area 61 is connected to the air inlet 11, the detergent can be quickly delivered to the washing chamber, and when the temporary storage area 61 is isolated from the air inlet 11, excess detergent is returned to the liquid storage tank to avoid leakage due to the temporary storage area 61 exceeding its capacity.

[0033] The cleaning method of the cleaning machine in this embodiment is as follows:

[0034] Initially, the damping component 5 is filled with detergent.

[0035] When the cleaning machine opens, the door 2 opens, causing the hinge 3 to flip forward. The damping component 5, which is linked to the hinge 3, gradually stretches. During the stretching process of the damping component 5, its piston structure pumps the detergent inside into the washing chamber of the cleaning machine, and at the same time, the detergent in the liquid storage tank 4 is replenished into the damping component 5. During the above-mentioned pumping process, the damping component 5 uses the pressure of the pumping process to provide damping for the door 2.

[0036] When the door is closed, the hinge 3 flips backward under the action of the door body 2, and the damping component 5, which is linked to the hinge 3, gradually retracts. During the retraction of the damping component 5, its piston structure transfers the detergent from the rear area to the front area, preparing for the detergent to be added when the door is opened again.

[0037] After closing the door, the washing program will begin.

[0038] In this embodiment, the hinge 3 and damping element 5 on the side of the door 2 form a structure that can pump detergent from the storage tank 4 during the opening and closing of the door. The piston structure formed by the damping element 5 can pump the detergent into the washing chamber. This structure not only eliminates the need for a separate drive mechanism and transmission mechanism, but also has a simple and reasonable structure, low cost, and eliminates the noise problem caused by the operation of the drive mechanism. At the same time, the pumping pressure generated during the delivery of detergent can produce a damping effect on the door 2, eliminating the need for a separate door 2 damping structure, further simplifying the structure of the cleaning machine and reducing production costs.
