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

[0046] This embodiment mainly solves the problem of how to accurately determine the water intake of a non-porous inner drum washing machine. The specific solution is as follows:

[0047]A drum washing machine, comprising an inner cylinder 17 and a water inlet pipeline connected to the inner cylinder 17, the inner cylinder 17 is a non-porous inner cylinder, which holds washing water when washing clothes, and the water inlet pipeline is provided for A flow sensor 1 that detects the flow of incoming water.

[0048] In this embodiment, a flow sensor 1 is installed on the water inlet pipeline to monitor the flow rate of water intake. When the set water intake volume is reached, the water intake valve 20 is closed to complete the water intake. In this embodiment, the flow sensor is used to solve the water inflow problem of the non-porous inner drum washing machine according to the set water level, ensuring the washing effect, simple structure and convenient operation.

[0049] Furt...

Embodiment 2

[0064] Such as Figure 2-Figure 4 As shown, a drum washing machine in this embodiment includes an inner cylinder 17 and a water inlet pipeline. The inner cylinder is a non-porous inner cylinder, which holds washing water when washing clothes, and also includes a measuring water for measuring the amount of water intake. device, the water inlet pipeline communicates with the water measuring device, and the water measuring device communicates with the inner cylinder.

[0065] The drum washing machine of this embodiment is provided with a water measuring device, and before entering the water into the inner tube 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 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 is...

Embodiment 3

[0077] This embodiment mainly solves the problem of how to ensure the unbalanced air pressure in the airtight compartment of the non-porous inner drum washing machine. Specifically, the sudden water cut-off of the solenoid valve, especially the water cut-off of the tap water pipe network, forms a negative pressure and returns the washing water in the airtight cabin Wash to the pipe network; or there is gas inside and it is difficult to enter the water.

[0078] Such as Figure 5-Figure 7 As shown, a drum washing machine in this embodiment includes an inner cylinder 17, which is a non-porous inner cylinder, which holds washing water when washing clothes, and also includes an inner cylinder for connecting the inner cylinder 17 with the external environment to balance the interior of the inner cylinder. Air pressure air pressure balance mechanism.

[0079] When water enters, the gas in the airtight compartment of the inner cylinder can overflow through the equalizing mechanism u...

Abstract

The present invention provides a drum washing machine and a control method thereof. The drum washing machine comprises an inner barrel and a water inlet pipeline communicating with the inner barrel; the inner barrel is a hole-free inner barrel and contains washing water during clothes washing; and the water inlet pipeline is provided with a flow sensor used for detecting inlet water flow. The present invention provides the drum washing machine which has the hole-free inner barrel and is of a front open type structure. The drum washing machine is simple in structure; the space between the innerbarrel and an outer barrel does not need to be filled with washing/rinsing water, so that the washing water amount of the washing machine is greatly reduced; and the inlet water flow is monitored byarranging the flow sensor on the water inlet pipeline, and when the set water inlet amount is reached, a water inlet valve is closed to finish water feeding, so that the problem that the water is fedto the drum washing machine with the hole-free inner barrel according to the set water level is solved.

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 the most widely used household appliance in people's daily life, washing machine helps people to get rid of the troubles of laundry and brings great convenience to people. But the washing machine also has certain disadvantages, such as long time-consuming, large water consumption, etc. With the development of society, water resources, as an important natural resource, become more and more important, and people's water-saving awareness is also increasing. 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 the washing machine, some patents have also been proposed now, such as the patent number 201410215346.3, which is named as a Chinese invention patent of a drum washing mac...
