摘要： Disclosed is a temperature control method for a clothes drying treatment device and a clothes drying treatment device. A heating device of the clothes drying treatment device executes an on or off operation in a temperature interval, when the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stopping heating; and the upper limit value TDx of the temperature interval decreases as a number of an off times x of the heating device increases. According to clothes drying treatment device, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shorten, and a certain coefficient is multiplied by in the following control parameters controlling on or off of the heating device, the coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases, and the on temperature is adjusted accordingly as the number of the on times of the heating device, and the contradiction between a high temperature required by a clothes dryer initially and a low temperature required in the later drying process is effectively balanced.

摘要： Disclosed are a clothing treating device and a control method therefor. The clothing treating device comprises at least one washing apparatus and at least one drying apparatus, wherein the washing apparatus comprises a water heater (5) for heating washing water, and the drying apparatus comprises a drying heater (6) for heating air entering the drying apparatus; when two or more heaters are working simultaneously, the total power thereof exceeds a bearing capacity of a power line; and when both a washing water heating program and a drying program need to be executed, the clothing treating device controls the water heater (5) and the drying heater (6), such that same do not work simultaneously, or adjusts the powers of the water heater (5) and the drying heater (6) so as to enable the two to work simultaneously. In this way, a user can give different heating control instructions at once or add different heating control instructions at any time, and the clothing treating device automatically controls the execution of the control instructions given by the user, thus ensuring the safe working of the clothing treating device within a rated power and ensuring the safety of the user.

摘要： The present disclosure discloses a control method of a multi-drum washing machine. The multi-drum washing machine includes at least two sets of washing devices. The control method includes setting an oscillating program in the multi-drum washing machine. The oscillating program is a program in which oscillation generated by at least one washing device is used as an oscillating source to drive washing water and laundries in another at least one washing device to generate an interaction and achieve a washing effect. Multiple sets of mutually connected washing devices are used. When at least one washing device oscillates, another at least one washing device and washing water and laundries in the washing device are driven to oscillate; and the vibration or jumping of the washing water in a drum is used to realize a function of soft washing of laundries and solve the problem of washing damage to soft laundries due to agitating type washing or beating type washing.

摘要： The relates to a heating control system of a multi-drum washing machine. The multi-drum washing machine comprises at least two sets of heating devices. The heating control system further comprises at least two detection units which are correspondingly connected with the heating devices, wherein each detection unit is used for detecting heating information of the corresponding heating device and controlling at least one other heating device to be turned on/off according to the heating information. The heating control system of the multi-drum washing machine provided by the disclosure solves the problem that it is difficult to detect heating devices in a multi-drum washing machine, thus increasing the calculation burden of a processor. The disclosure realizes real-time detection of the heating devices through simple detection circuit hardware connection on a circuit of each heating device, thus reducing the calculation burden of the processor of the multi-drum washing machine. According to the disclosure, the circuits are detected by using connection structures of circuit hardware, thereby saving cost, improving the sensitivity of the detection circuits and prolonging the service life of the processor of the multi-drum washing machine.

摘要： Disclosed is a water draining method of a washing machine. The water draining method comprises the following steps in order: a draining step, controlling a water drainage pump (4) to work intermittently until the water level inside an outer drum (2) reaches a set drainage water level; and a spin-drying step, controlling the electric motor to drive the inner drum to rotate to remove water, while also controlling the water drainage pump (4) to work intermittently. By controlling the water drainage pump (4) to work intermittently, when the water drainage pump (4) is working, the washing water inside the outer drum (2) enters a water drain pipe (3), and is then pumped by the water drainage pump (4) to be discharged via a riser segment of the water drain pipe (3); when the water drainage pump (4) stops working, the washing water in the riser segment of the water drain pipe (3) flows back under the action of gravity, and the the water drainage pump (4) alternately working and stopping makes the washing water in the riser segment also flow back intermittently, and that facilitates foam floating on the washing water being discharged outside the washing machine. Therefore, the rinsing effect of the washing machine is improved and foam overflow is avoided.
