Washing machine and control method thereof

Abstract

The invention discloses a washing machine. The washing machine comprises an outer barrel for containing washing water, an electromagnetic heating device is arranged at the bottom of the outer barrel and comprises a heat conduction plate and an electromagnetic heater, the heat conduction plate is arranged on the upper side of the bottom of the outer barrel and is an annular iron-containing plate body, and the electromagnetic heater is arranged on the lower side of the bottom of the outer barrel. When the water inlet temperature is low, the washing water can be heated, the heating area is large,the washing water is evenly heated, washing powder can be promoted to be dissolved in the washing water more quickly, the cleaning effect on clothes is enhanced, and after clothes washing is finished, no washing powder which is not dissolved in water is left on the clothes; the washing water is heated through the electromagnetic heating device so that clothes washing can be assisted, and the cleanliness degree of the clothes is improved; meanwhile, due to the fact that the electromagnetic heater is not arranged in the washing machine, the electric shock situation is avoided; and according tothe scheme, the washing machine is simple in structure and high in operability, and a control method of the washing machine is introduced.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine and a control method of the washing machine. Background technique [0002] When washing with a top-loading washing machine in winter, it takes a long time for the washing powder to fully dissolve in the water due to the low temperature of the inlet water, especially in places where the temperature in the north is very cold and the temperature of the inlet water is extremely extreme. It takes a lot of time to fully dissolve the powder. It is possible that the washing program has been running for a long time before the detergent is completely dissolved. Even after washing, the detergent is not completely dissolved in the washing water. There will be residues of washing powder. [0003] The technical scheme adopted in the prior art to solve this technical problem is to install a heating tube in the washing machine. The heating tube is arranged...

AI Technical Summary

Problems solved by technology

[0002] When washing with a top-loading washing machine in winter, it takes a long time for the washing powder to fully dissolve in the water due to the low temperature of the inlet water, especially in places where the temperature in the north is very cold and the temperature of the inlet water is extremely extreme. It takes a lot of time to fully dissolve the powder. It is possible that the washing program has been running for a long time before the detergent is completely dissolved. Even after washing, the detergent is not completely dissolved in the washing water. There will be residue of washing powder

[0003] The technical scheme adopted in the prior art to solve this technical problem is to install a heating tube in the washing machine. The heating tube is arranged on the upper side of the outer tub and sealed by rubber parts. The heating tube uses resistance wire to heat the water in the outer tub to heat to Preset temperature, but due to the limitations of the structure of the washing machine, the length of the heating pipe is not very long, and the area in contact with the water is also small, so its heating efficiency is very low, and it takes a long time to drain the water in the outer tub Heating to the set temperature takes time and consumes more electric energy. Moreover, if the heating tube is used for heating, if the sealing ring is not installed properly or is aging, water leakage will easily occur. If the heating tube is closed and damaged, the water will not enter If it is discovered in time, there is a high possibility of electric leakage, and when the resistance heating tube is used for a long time, it is easy to burn out due to loss, and its life is very short. Difficult to complete

[0004] Because the bottom of the outer tub is a load-bearing bottom, it has a certain thickness. In the prior art, the technology of using electromagnetic heating to heat the washing water in the outer tub is only to install an electromagnetic heater at the bottom of the tub and a The iron sheet cannot effectively heat the washing water in the outer bucket, and the heating range is small, and the washing water is heated unevenly. If the washing water needs to be heated up, the power of the electromagnetic heater must be adjusted to a high level. High, easy to burn the upper side of the outer barrel
