Abstract: A computer-implemented payment processing method includes receiving, from a computer device associated with a payee, a collection request, in which the collection request includes a payment account identifier and payment authorization information, and in which the payment account identifier and payment authorization information are provided by a payment service demander; identifying, by the payment server, stored payment authorization information, the stored payment authorization information corresponding to the payment account identifier, in which the stored payment authorization information comprises a specified image and information representing one or more password locations in the specified image; determining, by the payment server, that the stored payment authorization information matches the payment authorization information included in the collection request; and responsive to determining that that the stored payment authorization information matches the payment authorization information included in t

Abstract: One or more implementations shown in the present specification provide an offline payment method. A communication connection between a collection device and a payment device is established, wherein both the collection device and the payment device are in an offline state. Payment data sent by the collection device is received by the payment device through the communication connection established to the collection device. Payment processing based on the payment data and account information of the payment device is performed by the payment device, to obtain a payment result. The payment result is returned, by the payment device to the collection device through the communication connection. Collection processing is performed, by the collection device, based on the payment result and obtained account information of the payment device, to obtain a collection result.

Abstract: An efficient washer-dryer and a control method are provided. The efficient washer-dryer comprises a laundry accommodating drum, a drying air duct arranged outside and communicated with the laundry accommodating drum, and a condensing device provided with a heat-absorbing portion and a heat-releasing portion. The heat-absorbing portion is arranged in the drying air duct, and the heat-releasing portion is arranged outside the drying air duct. At least a nozzle spraying water towards the condensing device and a drain outlet communicated with an exterior of the drying air duct are arranged inside the drying air duct. The control method of the washer-dryer comprises: at least after a drying process, supplying water to the nozzle to flush the dirt attached on the condensing device, and discharging flushed water and dirt out of the drying air duct through the drain outlet. The condensing efficiency of the washer-dryer is significantly improved, drying time is shortened.

Abstract: A door for a drum washing machine comprises an inner frame, a glass tub, a middle frame, a window screen and an outer frame which are arranged sequentially from the inner side of the door to the outer side of the door. The middle frame is in welded connection with the inner frame, the glass tub is clamped between the inner frame and the middle frame, the outer frame is in snapped connection with the middle frame and/or the inner frame, and the window screen is clamped between the outer frame and the middle frame. The window screen is free of snap jaw, so that the structure is simplified, and production of the window screen is accelerated.

Abstract: Disclosed is a dryer or a washer dryer, including at least a clothes drying system, where the clothes drying system includes a heating structure and a condensing structure; the condensing structure is arranged on a lower part of the dryer or the washer dryer; the condensing structure includes an air inlet and an air outlet for hot air, and further includes a gas inlet and a gas outlet for cold air, and a heat exchanger is arranged inside the condensing structure; the heat exchanger is composed of fins which are superposed in a longitudinal-transverse alternating manner, and a frame with an enclosure structure is arranged outside the heat exchanger.

Abstract: An outer drum of a washing machine is provided, and relates to the technical field of washing machines. Two opposite side walls of the outer drum of the washing machine are formed as non-circular surfaces to avoid collision with side plates of a housing. A washing machine having the above outer drum is further provided.

Abstract: Disclosed is a superposed heat exchanger, including a plurality of fins superposed up. Two opposite side edges of each fin are bent upwards to form a ventilating air path in coordination with an upper fin, and adjacent fins are arranged in a mode of vertical-horizontal alternating so as to form horizontal air paths and vertical air paths independent from each other with up-down intervals.

Abstract: A drum washing machine is provided with a double spraying system used for washing the window and the window gasket ring respectively. A first spraying nozzle is connected with the inlet solenoid valve of the washing machine to wash the outer surface of the watching window and the window gasket ring, and a second spraying nozzle to wash the folded inner wall of the window gasket ring. The spraying nozzles are connected to the solenoid valve through a three-way pipe, or connected to the solenoid valve of the washing machine through respective pipes. The double spraying system intakes water and soaks the clothes in the washing process, and/or intakes water and sprays the watching window and the window gasket ring simultaneously, and/or sprays the watching window and the window gasket ring when dehydrating the clothes in the dehydrating process.

Abstract: Disclosed are a washing machine for automatically feeding additives and a method thereof. The washing machine includes an additive automatic feeding apparatus and at least one additive accommodating box for accommodating at least one liquid additive. Each additive accommodating box is of a structure of an independently sealed cartridge-type box. A washing machine casing is provided with at least one opening. Each additive accommodating box is disposed inside its corresponding opening in a pull and push manner and operably is or is not in communication with the additive automatic feeding apparatus.

Abstract: Disclosed are a door-opening indicator for a drum washing machine and a control method therefor. A door body is provided with a door lock for locking and unlocking the door body that is controlled by a computer programmable controller of the washing machine. The door-opening indicator is provided on the door body of the drum washing machine and/or on the front surface of the washing machine and includes a touch sensing device and a colour-changeable indicator lamp set that are connected to the computer programmable controller.
