Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a dishwasher with a residue crushing device. Background Art

[0002] After washing dishes in a dishwasher, there will generally be washing residues. If the residues are not cleaned first, the dishwasher drain port may be blocked. If bones or toothpicks flow in, the pipe wall may be punctured and leaks may occur. To solve this technical problem, there are several existing dishwasher residue crushing treatment methods: ① Add a small blade to the washing pump to break the residue; ② An external washing residue treatment device is used to treat the residue separately; ③ A blade is set in the sink under the flat filter, and the motor is external. ① The blade is on the washing pump, and the blade needs to be in the sink. This feature is destined to require a large space in the water wipe to achieve this. In fact, the available space of the dishwasher is limited and it is difficult to layout; ② The residue is treated separately instead of being directly treated and then eliminated. There is still a risk of clogging the drainage channel, and the cost is also high; ③ The direct drive of the motor requires a lot of power, and is generally placed at the bottom of the sink. The space required is large and there are also problems of leakage and drainage, and the residue or wastewater residue cannot be solved.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dishwasher with a residue crushing device, which is provided with an upper and lower set of crushing tools with different rotation directions. The transmission ratio is changed by changing the torque transmitted by the gear set, so that low-speed input and high-speed output can be achieved, and the reliability is high. A shearing-type crushing method is formed between the two sets of crushing tools, which is more efficient and the crushing is finer.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dishwasher with a residue crushing device, including a sink of the dishwasher, a drainage device arranged under the sink, and a crusher located between the sink and the drainage device, and the crusher is provided with at least two groups of crushing tools with different rotation directions.

[0007] The pulverizer is equipped with a first pulverizing tool and a second pulverizing tool located below the first pulverizing tool, and the dishwasher is also provided with a driving device for driving the first pulverizing tool and the second pulverizing tool to rotate. The first pulverizing tool and the second pulverizing tool are arranged on different horizontal planes up and down, and rotate in different directions, so as to form a shearing-type pulverizing mode between them, which is more efficient and pulverizes finer particles.

[0008] The driving device includes a power supply device, a power transmission device that connects the power supply device and the crushing tool with low speed input and high speed output, and the power supply device is a motor. The power supply device provides rotational power for the crushing tool, and the power transmission device transmits the power to the crushing tool, and realizes low speed input and high speed output, so that the rotation speed of the crushing tool is increased, and the efficiency of the crushing tool is greatly improved.

[0009] The power transmission device includes a power input end connected to the power supply device, a first power transmission device for driving the first crushing tool to rotate, and a second power transmission device for driving the second crushing tool to rotate. The high-speed rotation of the crushing tool is achieved through the input of power, the increase of the rotation speed, and the power output after the increase of the rotation speed, and the power transmission paths for driving the first crushing device and the second crushing device to rotate are different, so that the first crushing device and the second crushing device rotate asynchronously.

[0010] The second power transmission device includes a gear speed increaser connected to the power input end, a second crushing gear connected to the second crushing tool through a connecting pipe, and the second crushing gear is meshed with the gear speed increaser.

[0012] The power input end is a first end face gear, which meshes with a common cylindrical gear and can change the transmission direction of power.

[0013] The second grinding gear is a cylindrical gear.

[0014] The first grinding gear is a cylindrical gear.

[0015] The first crushing tool and the second crushing tool are both blades, and the blades are more likely to chop up the residue and improve the crushing efficiency.

[0019] 3. The power transmission device includes a power input end connected to the power supply device, a first power transmission device for driving the first crushing tool to rotate, and a second power transmission device for driving the second crushing tool to rotate.
