Description

Food waste disposer and integrated kitchen appliance

Technical field

The invention belongs to the technical field of kitchen garbage disposal equipment, and specifically relates to a food garbage disposer and an integrated kitchen appliance.

When people wash pots and pans daily, food waste easily flows into the sewer directly with water. After a long time, it is easy to block the sewer, which brings great trouble to family life. The emergence of food waste disposer solves this problem.

At present, the food waste disposer in the industry is a household kitchen appliance that drives the grinding disc to rotate through the drive unit, so that the food waste and the parts on the grinding disc collide, cut, and rub, so as to reduce the volume and directly remove it through the sewer. .

The food waste disposer mainly contains a grinding system; the main function of the grinding system is to carry out grinding operations, which will impact, knock, cut, and grind the larger food waste, and finally turn it into particles of about 2mm, which will be discharged through the sewer. ; Now the waste disposer basically relies on the flushing effect of water flow, so after the waste is processed, the water flow needs to be maintained for more than 10 seconds before the waste can be completely washed away. Then when the water flow is small or there are many detours in the pipeline, the garbage is easy to accumulate in the pipeline. Over time, the pipeline is blocked. Makes the use of garbage disposal an embarrassing thing.

In view of this, the present invention is proposed.

Outlet 3, the residue outlet 3 is provided with a sewage pipe 20; the drainage assisting device is connected with the sewage pipe 20, and is used to assist the residue in the sewage pipe 20 to discharge.

Specifically, as shown in Figure 1, a rotatable grinding assembly 2 is provided in the grinding chamber 9. The grinding assembly 2 includes a grinding disc 8 and a grinding sheet. The grinding chamber 9 has a garbage inlet and a residue outlet 3, and the garbage inlet is suitable for The sink is connected, or the garbage inlet is connected with the outlet of the dishwasher, or the garbage inlet is connected with the outlet of the sink and the dishwasher, the kitchen waste enters the crushing chamber 9 through the sink or the dishwasher through the garbage inlet, the crushing chamber The grinding assembly 2 in 9 smashes and grinds the kitchen waste under the action of the drive unit 13, so that the kitchen waste is more refined. The treated kitchen waste is discharged into the sewer through the residue outlet 3 through the sewage pipe 20 or other In the sewage equipment. At the same time, the drainage assistance device connected with the sewage pipe 20 passes a high-speed airflow into the sewage pipe 20. Under the action of the high-speed airflow, the downstream area in the sewage pipe 20 forms a negative pressure zone, so that the treated residue is more refined. As a result of the additional negative pressure, the discharge from the sewage pipe 20 is accelerated to reduce the risk of the residue blocking the sewage pipe 20.

In detail, the drainage assisting device includes an air duct 6 for introducing gas into the sewage pipe 20, one end of the air duct 6 is connected with the sewage pipe 20, and the other end is connected with an air supply assembly.

The end of the branch pipe 5 away from the sewage pipe 20 is connected to The air duct 6 is connected. There is a certain angle A between the central axis of the branch pipe 5 and the central axis of the sewage pipe 20, so that the angle A between the discharge direction of the residue in the main pipe 4 and the direction in which the air flow in the branch pipe 5 enters the main pipe 4 is less than 90 °, so that the negative pressure zone formed by the high-speed airflow in the sewage pipe 20 is located downstream of the connection between the main pipe 4 and the branch pipe 5, preventing the residue from flowing back in the main pipe 4 and blocking the sewage pipe 20.

Further, the branch pipe 5 communicates with the main pipe 4 through the first air inlet hole 16; the first air inlet hole 16 is provided on the side wall of the main pipe 4, and the diameter of the first air inlet hole 16 It is smaller than the inner diameter of the branch pipe 5 to form an air intake supercharging structure. Preferably, the diameter of the first air intake hole 16 is in the range of 1 to 3 mm, preferably 2 mm. When the air supply assembly passes the gas into the sewage pipe 20 through the air guide pipe 6, the first air inlet 16 with a smaller diameter can compress the gas and increase the speed of the air flow into and out of the sewage pipe 20, which is beneficial to the sewage pipe 20.
