Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] The invention provides a washing machine, such as figure 1 As shown, the washing machine includes an inner cylinder 1 made of metal, an insulating outer cylinder 2, a magnetic induction coil 3 located outside the outer cylinder 2, and a controller (not shown) for controlling the power on and off of the magnetic induction coil 3 . When the heating program of the washing machine starts, the washing machine converts the current into high-frequency alternating current exceeding the audio frequency, and outputs the high-frequency alternating current to the magnetic induction coil 3, thereby generating a high-frequency alternating magnetic field. At this time, the magnetic induction coil 3 generates The sense wire passes through the insulating outer cylinder 2 and acts on the inner cylinder 1 made ...

Abstract

The invention belongs to the technical field of laundry equipment and discloses a washing machine. The washing machine comprises a metal inner barrel and an insulated outer barrel, and further comprises a magnetic induction coil located on the outer side of the outer barrel, wherein magnetic induction lines generated by the magnetic induction coil during electrification can heat the inner barrel.The magnetic induction coil is arranged on the outer side of the outer barrel, when the magnetic induction coil is electrified, the generated magnetic induction lines act on the inner barrel, and strong eddy currents are generated in the inner barrel due to electromagnetic induction; when the eddy currents flow against internal resistance of the inner barrel, conversion into heat energy from electric energy is completed, the inner barrel is heated, and then washing water in the outer barrel is heated by the heated inner barrel. By means of the structure, design of a groove of the existing outer barrel is avoided, space occupied by the outer barrel is reduced, and deposition of a detergent in the groove can be avoided; the inner barrel can be heated uniformly, and potential safety hazards caused by condensed water generated in the washing machine can be reduced.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a washing machine. Background technique [0002] With the improvement of people's quality of life, the performance requirements of washing machines are also getting higher and higher. No matter the existing washing machine is a drum washing machine or a wave-wheel washing machine, a heating function is added, that is, the washing effect is improved by heating the washing water. Taking the drum washing machine as an example, a groove is usually provided at the bottom of the outer cylinder at present, and a heating element is installed in the groove, and the washing water between the outer cylinder and the inner cylinder passes through the heating element. But the above structure has the following problems: [0003] 1. The existing heating element is arranged in the groove at the bottom of the outer cylinder, which needs to occupy the space of the outer cylinder. [00...
