Problems solved by technology

[0006] The above-mentioned invention patent application adopts the method of electromagnetic heating to realize the heating of the washing water of the drum washing machine with no hole in the inner cylinder, but since the electromagnetic heating module is arranged in the outer cylinder, when the washing machine is draining, the discharged washing water will submerge the electromagnetic heating module and discharge The washing water will inevitably contain debris such as lint
If the lint remains on the electromagnetic heating module during the drainage process, the temperature of the electromagnetic heating module itself is high during heating, which may cause the burning of the residual lint; if iron-containing debris remains on the electromagnetic heating module during the drainage process , the electromagnetic heating module will heat it during heating, causing the electromagnetic heating device to fail or even burn out

Embodiment 1

[0032] Such as Figure 1-Figure 3 Shown, a kind of washing machine of the present embodiment comprises:

[0033] An outer cylinder 4, the outer cylinder 4 is provided with a drain port 20;

[0034] The inner cylinder 5 is arranged in the outer cylinder 4 and has a washing chamber independently containing washing water;

[0035] And an electromagnetic heating device, which is arranged in the outer cylinder 4, and correspondingly heats the cylinder wall of the inner cylinder 5;

[0036] The electromagnetic heating device is arranged obliquely downward toward the water outlet 20, and / or the cylinder wall of the outer cylinder 5 is arranged obliquely downward from the location where the electromagnetic heating device is installed to the water outlet.

[0037] This embodiment adopts the wireless heating method of electromagnetic heating to realize the heating of the washing water of the washing machine without water between the inner cylinder and the outer cylinder during the was...

Embodiment 2

[0051] The control method of the washing machine in this embodiment includes: when the washing machine executes the last rinsing program and / or the dehydration program, the electromagnetic heating device is controlled to turn on the heating inner cylinder. This embodiment realizes the thermal dehydration of the clothes, the electromagnetic heating device heats the inner cylinder, and the clothes have a lower moisture content, which is convenient for quick drying / drying / drying, and improves the user experience.

[0052] Further, the dehydration program of the washing machine in this embodiment includes an accelerated dehydration stage in which the rotation speed of the inner tub gradually increases and a stable dehydration stage in which the rotation speed of the inner tub remains constant. The washing machine controls the electromagnetic heating device to turn on heating the inner tub at least in the accelerated dehydration stage.

[0053] When the washing machine in this embod...

Embodiment 3

[0068] Such as Figure 1-Figure 3 As shown, the present embodiment provides a washing machine, comprising:

[0069] Outer cylinder 4;

[0070] The inner cylinder 5 is arranged in the outer cylinder 4;

[0071] The electromagnetic heating coil 8 is arranged on the outer cylinder 4;

[0072] And the electromagnetic heating driver 7 is electrically connected with the electromagnetic heating coil 8, and the electromagnetic heating driver 7 rectifies the alternating current into direct current, and then converts the direct current into high-frequency alternating current;

[0073] The electromagnetic heating driver 7 outputs high-frequency alternating current to the electromagnetic heating coil 8, thereby generating a high-frequency alternating magnetic field, and the inner 5 generates heat due to electromagnetic induction in the high-frequency alternating magnetic field, thereby heating the inner The water in cylinder 5.

[0074] The heating / drying program of the washing machin...

Abstract

The invention provides a washing machine, which comprises an outer barrel, an inner barrel and an inner barrel, the inner barrel is arranged in the outer barrel and is provided with a washing cavity for independently containing washing water; the electromagnetic heating device is arranged in the outer cylinder and correspondingly heats the cylinder wall of the inner cylinder; and the electromagnetic heating device is obliquely and downwards arranged towards the water outlet, and/or the barrel wall of the outer barrel is obliquely and downwards arranged between the position where the electromagnetic heating device is arranged and the position of the water outlet. In the water drainage process of the washing machine, washing water can be better guided to the water drainage opening, sundries such as thread scraps are prevented from being left on the electromagnetic heating device, the flow speed of water flow is increased through the height difference arrangement mode, the washing effect is achieved, the sundries such as the thread scraps can be washed and discharged, and the service life of the washing machine is prolonged. The possibility that sundries such as wire scraps remain on the electromagnetic heating device in the drainage process is further avoided, and the working safety of the electromagnetic heating device is improved.

Description

technical field [0001] The present invention relates to the technical field of laundry equipment, in particular to a 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. However, the existing washing machines generally include an inner cylinder and an outer tub, and a plurality of dehydration holes are distributed on the barrel wall of the inner tub, and during the washing process, the washing water between the inner tub and the outer tub will not be used, causing this part of the washing Water is wasted, and the dirt generated during the washing process will accumulate as the water flows between the inner cylinder and the outer tub. With long-term use, the accumulation of dirt will affect the washing effect and reduce the user experience. [0003] In order to solve the above problems, some patents have also...
