Abstract: Provided are a method and apparatus for determining a blockage of a filter of a clothes dryer and a clothes dryer. The clothes dryer includes a motor. The method includes following steps. An actual rotational speed of the motor is acquired, and an electrical parameter corresponding to a rotational speed range to which the actual rotational speed belongs is determined as a first threshold corresponding to the actual rotational speed; an actual clothes volume in the clothes dryer is acquired, and the first threshold is corrected according to a correction coefficient corresponding to a clothes volume range to which the actual clothes volume belongs so that a second threshold is obtained; and an actual electrical parameter of the motor is acquired, and when it is detected that the actual electrical parameter is less than the second threshold, it is determined that the filter of the clothes dryer is blocked.

Abstract: The present invention relates to a method for calculating a head loss coefficient and branch pipe flow distribution of a multi-point water intake. The method includes the following steps: inputting and determining a structure and size information of the multi-point water intake; determining a head loss coefficient; determining a head loss coefficient form of a confluence port; pre-estimating or adjusting a trial flow; performing trial calculation on the head loss coefficient of each branch pipe; comparing the head losses calculated by two flow paths; and carrying out overall calculation. According to the present invention, the flow of each branch pipe is adjusted and the head loss coefficient is repeatedly calculated by utilizing iterative calculation of the head loss coefficients of the flows in two directions, so that the head loss and the flow distribution proportion can be finally and accurately calculated.

Abstract: A network adapter (20) functioning as an intermediary between a microprocessor (25) and a network (15) includes a communication protocol (43) compatible with a network protocol and an interpreter (45) compatible with a programming language of the microprocessor (25). The network adapter (20) reformats a signal received from a network interface (12) and following the network protocol into a signal compatible with the microprocessor programming language and transmits the reformatted signal to the microprocessor (25). The network adapter (20) also transforms a signal received from the microprocessor (25) into a signal compatible with the network protocol and transmits the transformed signal to the network interface (12). The network adapter (20) is capable of establishing a network communication for various kinds of microprocessors without significantly modifying or reprogramming the microprocessors.

Abstract: A network server (20) establishes communication between devices (15A-15N) in an Intranet (16) and a network (11). The network server (20) has a database (30) storing device property tables (35A-35N) and object property tables (A1-Ai, B1-Bj, . . . , N1-Nk), which are periodically mapped from the devices (15A-15N). The database (30) enables the identification, description, controlling, monitoring, and modification of the objects in a device (15A) from multiple clients on the network (11). The database (30) further allows the exchange of date among the devices (15A-15N) in the Intranet (16). The database (30) also provides a platform and independent communication process between the network (11) and the devices (15A-15N).
