A drum washing machine outer cylinder and a drum washing machine

Abstract

The invention provides an outer cylinder of a drum washing machine and a drum washing machine. The outer cylinder includes a cylinder body and a water injection port opened on the cylinder body and communicated with a water inlet pipe. When the inner cylinder rotates at a high speed, the baffle enters into the water injection port, and the baffle is arranged on the inner wall of the cylinder and extends inward. By setting the baffle, the high-speed water flow will pass over the baffle when it encounters the baffle, and form a stable area with reduced flow on the back of the baffle, and set the water injection port in the stable area, that is, at the water injection port The water flow or foam flow at the place will be reduced, thereby reducing the chance of water and foam flowing into the water injection port, effectively preventing the overflow of water or foam, and improving customer satisfaction; and the structure of the baffle is simple, which is conducive to increasing The reliability of the structure is beneficial to reduce the manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to an outer drum of a drum washing machine and a drum washing machine with the outer drum. Background technique [0002] The drum washing machine includes a water inlet box arranged above the outer tub, and a water inlet pipe connects the water inlet box and the outer tub to guide the liquid in the water inlet box into the outer tub. [0003] When the washing machine is working, water or foam will be thrown into the water inlet pipe when the water flow rotates at a high speed with the inner drum. For example, excessive detergent addition, water temperature heating, or vibration of the outer drum will cause excessive foam in the outer drum. , the pressure inside the outer cylinder increases, so that the foam or water thrown into the water inlet pipe flows upwards along the water inlet pipe, and flows out of the washing machine body through the water inlet box, wh...

Problems solved by technology

[0003] When the washing machine is working, water or foam will be thrown into the water inlet pipe when the water flow rotates at a high speed with the inner drum. For example, excessive detergent addition, water temperature heating, or vibration of the outer drum will cause excessive foam in the outer drum. , the pressure inside the outer cylinder increases, so that the foam or water thrown into the water inlet pipe flows upwards along the water inlet pipe, and flows out of the washing machine body through the water inlet box, which brings unnecessary cleaning troubles to the user

[0004] In order to solve the above-mentioned overflow problem, at present, a one-way structure is generally added to the water inlet pipe, that is, it is necessary to add brackets and blocking caps and other components similar to one-way valves to the original pipeline structure. The increase of components often reduces the operation of the whole machine reliability, because the increase of components will cause defects such as defective components, improper assembly, and aging failure during use; in addition, the increase of components will increase the difficulty of assembly and increase the cost. In the case of low-frequency vibration, the one-way valve will open and close according to the vibration frequency, and the probability of water and foam overflow will also increase
