Description
Technical Field
The invention relates to the technical field of washing devices, in particular to a washing machine and a control method thereof.
Background
In the existing washing machine, in order to improve the cleanliness of washing, a washing water heating function is added more and more. For example, a drum washing machine has a water-saving feature, and uses a small amount of water for washing, generally about 20L, and generally has a heating function for improving the cleanliness of washing. The washing water is heated to set temperature (such as 40 deg.C, 50 deg.C, 60 deg.C, etc.), so that the cleanliness of washing is greatly raised. In order to realize the heating function of the washing water, a heater is arranged in the outer cylinder of the washing machine, and in order to ensure the safety, a groove structure is designed on the outer cylinder and used for accommodating the heater. The washing drum unit of the existing drum washing machine is shown in fig. 1 and 2.
As shown in fig. 1, the structure of the tub 100 of the prior art washing machine is mainly shown: the device mainly comprises a front cylinder shell 101 and a rear cylinder shell 102, wherein the connecting parts 103 of the two cylinder shells are connected together, specifically, connected through screws or bolts. In order to place the heater, since the gap between the inner and outer tubs of the washing machine is small, a groove structure 200A for accommodating the heater can be designed only at the bottom of the outer tub.
As shown in fig. 2, a cross-sectional view of a prior art wash drum unit is shown: the motor 600 is connected to the inner barrel 400 through a shaft, and can drive the inner barrel 400 to rotate. The outer cylinder 100 is formed by connecting a front cylinder shell 101 and a rear cylinder shell 102, and the connecting part 103 is provided with a sealing strip 500 to ensure that the outer cylinder 100 is watertight. The lowest position of the groove structure 200A is provided with a water outlet 700A, and water in the washing tub can be discharged through a water discharge pipe to a water discharge valve or a water discharge pump.
In the washing drum unit of the existing washing machine, after the detergent or washing powder is brought to the outer drum by the washing box assembly (not shown), the detergent or washing powder is easily deposited at the groove structure, and a part of the detergent or washing powder enters the drain pipe connected with the drain valve or the drain pump through the drain opening. And the water storage capacity in the groove structure and the water discharge pipe connected with the water discharge valve or the water discharge pump is about 2L. Therefore, even if the motor drives the inner barrel to rotate, the washing water is disturbed rapidly to dissolve detergent or washing powder, a dead angle is formed due to small water disturbance at the groove structure, and particularly, water in the drainage pipe connected with the drainage valve or the drainage pump is basically dead water. And the detergent or washing powder just entering the washing machine is deposited or falls on the washing machine, cannot be dissolved or has extremely poor dissolving efficiency, so that the efficacy of the detergent or washing powder is greatly reduced, and the washing ratio is low.
Therefore, the structural design of the outer drum of the existing washing machine causes detergent or washing powder to be easily deposited on the outer drum, and the detergent or the washing powder cannot be dissolved, so that the efficiency of the detergent is greatly reduced. The existing drum washing machine generally adopts an upper drainage mode to drain water, a drainage pump is adopted to drain the water in an outer drum out of the washing machine, and finally, part of water remains in the drainage pipe and is mixed with detergent or washing powder which is not completely dissolved, so that pollution is easily caused.
