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

Embodiment 1

[0129] This embodiment mainly solves the problem of how to ensure the unbalanced air pressure in the sealed cabin of the inner cylinder of the drum washing machine. Specifically, the water inlet valve is suddenly closed and the water is cut off, or the water pipe network is cut off, forming a negative pressure to pump the washing water in the sealed cabin of the inner cylinder. to the pipe network; or there is gas inside the inner cylinder, making it difficult to enter the water.

[0130] Such as Figure 9 to Figure 11 As shown, the drum washing machine described in this embodiment includes an inner cylinder 17, which is a non-porous inner cylinder, which is a water container 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.

[0131] When water enters, the gas in the airtight compartment of the inner cylinder ca...

Embodiment 2

[0144] Different from the first embodiment above, the air pressure balance mechanism described in this embodiment includes a booster mechanism and / or a pressure relief mechanism for communicating the inner cylinder with the external environment to balance the air pressure inside the inner cylinder 17 .

[0145]The pressurization mechanism described in this embodiment includes a pressurization channel 28 and a negative pressure safety valve 29. The negative pressure safety valve 29 is arranged on the pressurization channel 28, and is used for single-use when the internal pressure of the inner cylinder 17 is lower than the atmospheric pressure of the external environment. The guide guides the pressurized hole 28, and the external environment gas enters the interior of the inner cylinder 17 through the pressurized hole 28 to be pressurized until the internal air pressure of the inner cylinder 17 is balanced with the external environment air pressure, and the negative pressure safet...

Embodiment 3

[0161] This embodiment mainly solves the problem of how to ensure that the inner cylinder serves as a water container to enter the inner cylinder of the drum washing machine.

[0162] Such as Figure 17 As shown, the drum washing machine described in this embodiment includes an outer cylinder 18, an inner cylinder 17, an inner cylinder shaft 13 and a water inlet device. The inner cylinder 17 is a water container when washing clothes, and the inner cylinder 17 passes through the inner cylinder. The cylinder shaft 13 is rotatably supported in the outer cylinder 18, and the inner cylinder shaft 13 has a hollow passage 14 inside, and the water inlet device communicates with the sealed compartment inside the inner cylinder 17 through the hollow passage 14 of the inner cylinder shaft 13.

[0163] The water inlet device described in this embodiment includes a water inlet pipeline, one end of the water inlet pipeline communicates with the water inlet valve and / or the detergent dispens...

Abstract

The invention discloses a roller washing machine. The roller washing machine comprises an inner barrel, an outer barrel, a pneumatic balancing mechanism and a water inlet device, wherein the inner barrel is rotatably arranged in the outer barrel by virtue of an inner barrel shaft, the inner barrel is used as a water storage container when clothes are washed, a water outlet and a sealing valve fornormally closing the water outlet are formed in and arranged on the circumferential wall of the inner barrel, the water outlet can be opened by the sealing valve under the centrifugal action when theinner barrel rotates at the speed above the set rotating speed, the pneumatic balancing mechanism is used for communicating the inner barrel with the external environment so as to balance the internalpressure of the inner barrel, a hollow channel is formed in the inner barrel shaft, the water inlet device communicates with the interior of the inner barrel through the hollow channel of the inner barrel shaft, the pneumatic balancing mechanism is arranged on the inner barrel shaft, and a non-contact heating module is arranged on the outer barrel and does not make contact with the inner barrel so as to heat the washing water stored in the inner barrel. The roller washing machine has the characteristics of water conservation and cleanness.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a drum washing machine. 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. For example, the application number is CN201410215346.3, and the name is a Chinese invention patent of a drum washing machine. There is a door s...
