The invention relates to a numerically-control hydraulic muting type household elevator. An elevator car is connected with a single-acting oil cylinder through a steel wire rope. A hydraulic oil way structure connected with the single-acting oil cylinder is specifically characterized in that a servo motor is connected with a hydraulic pump, an oil inflow/outflow opening in the lower end of the hydraulic pump is connected with an oil tank, and an oil inflow/outflow opening in the upper end of the hydraulic pump is connected with an oil opening of the single-acting oil cylinder through a proportional flow control valve. The oil way between the single-acting oil cylinder and the proportional flow control valve is provided with a hydraulic pressure control switch. The domestic elevator is stable and comfortable in operation, no abnormal feeling exists in the lifting process, noise is extremely low, operation is safe and reliable, energy is saved, and the numerically-control hydraulic muting type household elevator can especially meet the requirements of the high-end market.
