Problems solved by technology

Because clothes must be soaked in a certain amount of washing water, if you want to achieve the effect of soaking, you need to store a certain amount of water in the non-porous inner cylinder, which will increase the burden on the motor and cause problems such as power consumption.
In addition, the water intake method of the drum washing machine disclosed in this patent is through the door seal. Since the main function of the door seal is to realize the sealing of the drum mouth of the outer cylinder of the washing machine, setting the water inlet conduit on the door seal will easily affect the sealing effect of the door seal, and it is not easy Realized, and this patent cannot realize the detection of the water level in the inner cylinder

Embodiment 1

[0060] This embodiment mainly solves the problem of how to accurately determine the water intake of the non-porous inner drum drum washing machine, and the specific scheme is as follows:

[0061] A drum washing machine, comprising an inner cylinder 17 and a water inlet pipeline communicated with the inner cylinder 17, the inner cylinder 17 is a non-porous inner cylinder, and holds washing water when washing clothes, and the water inlet pipeline is provided for Flow sensor 1 that detects the flow of incoming water.

[0062] In this embodiment, a flow sensor 1 is installed on the water inlet pipeline to monitor the flow rate of the water inlet. When the set water inlet amount is reached, the water inlet valve 20 is closed to complete the water inlet. This embodiment adopts the flow sensor to solve the problem of water inflow according to the set water level of the non-porous inner drum washing machine, ensures the washing effect, has a simple structure and is convenient to opera...

Embodiment 2

[0078] like Figure 2-Figure 4 As shown, a drum washing machine in this embodiment includes an inner tub 17 and a water inlet pipeline. The inner tub is a non-porous inner tub, which holds washing water when washing clothes, and also includes a quantity of water for measuring the water intake. The water inlet pipeline is connected with the water measuring device, and the water measuring device is communicated with the inner cylinder.

[0079] The drum washing machine of this embodiment is provided with a water measuring device, and before the water is fed into the inner tub 1, it enters the water measuring device for quantitative measurement, and determines the number of times the water measuring device measures water according to the set water level, thereby solving the problem of solving the problem. The non-porous inner drum washing machine ensures the washing effect according to the water inflow problem of the set water level, and has a simple structure and convenient oper...

Embodiment 3

[0091] This embodiment mainly solves the problem of how to ensure the unbalanced air pressure in the airtight chamber of the non-porous inner drum washing machine. Specifically, the sudden water cutoff of the electromagnetic valve, especially the water disconnection of the water pipe network, forms a negative pressure, and the washing water in the airtight chamber is returned to the air. Wash to the pipe network; or there is gas inside, and it is difficult to enter the water.

[0092] like Figure 5-Figure 7 As shown, a drum washing machine in this embodiment includes an inner tub 17, the inner tub 17 is a non-porous inner tub, which holds washing water when washing clothes, and also includes a connection between the inner tub 17 and the external environment to balance the interior of the inner tub Air pressure balance mechanism.

[0093] When water enters, the gas in the sealed chamber of the inner cylinder can be overflowed through the equalizing mechanism under pressure to...

Abstract

The invention provides a drum washing machine and a method for controlling the same. The drum washing machine includes an inner tub, which contains washing water when washing clothes, and the inner tub is provided with a plurality of annular water collecting grooves along the circumference of the inner wall and penetrating through the inner tub along the axial direction. The axial water collecting tank is communicated with the annular water collecting tank; a drainage device is arranged in the annular water collecting tank. The drum washing machine of the present invention has an annular water collecting tank on the inner wall of the inner drum, and N wave peaks and trough structures are formed on the inner drum wall surface, so that the centrifugally discharged water can be collected in each annular water collecting tank; the inner wall of the inner drum has an axial groove structure, so The axial groove realizes the communication of the annular water collecting grooves, so that the water in each annular water collecting groove can be collected more quickly and easily and then discharged through the drainage device, so as to achieve high-efficiency drainage and dehydration drainage.

Description

technical field [0001] The present invention relates to the technical field of laundry equipment, in particular, to a drum washing machine and a control method thereof. Background technique [0002] As one of the most widely used household appliances in people's daily life, washing machines help people get rid of the trouble of laundry and bring great convenience to people. However, the washing machine also has certain shortcomings, such as time-consuming and large water consumption. Therefore, how to realize the water-saving function of the washing machine is particularly important. [0003] In order to solve the water-saving problem of washing machines, some patents have been proposed. For example, the patent number is 201410215346.3, which is called a Chinese invention patent for a drum washing machine. The invention relates to a drum washing machine, including a box body. There is a door seal between the outer cylinder and the box body, the inner cylinder is connected ...
