Embodiment Construction

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0020] Considering that, for large-capacity (14-20kg) pulsator washing machines, a special structure clutch is used. When the pulsator rotates, the outer tub will rotate, and the accuracy of the Hall pulse counting method will be affected; when the load is full or close to full If the driving motor is in a saturated state, the weighing algorithm of the inverter depending on the motor parameters cannot accurately distinguish the weight change, and the accuracy of the weighing result cannot be guaranteed. The embodiment of the prese...

Abstract

The invention discloses a weighing method for a variable- frequency pulsator washing machine. The weighing method comprises the following steps that the variable- frequency pulsator washing machine operates according to weighing beats after receiving a weighing order; the variable- frequency pulsator washing machine respectively executes a transducer weighing procedure and a Hall pulse counting weighing procedure to weigh upon operating the weighing beats; the variable- frequency pulsator washing machine acquires weighing results of the transducer and the Hall pulse counting weighing results; and a final weighing value is acquired according to the weighing results of the transducer and the Hall pulse counting weighing results. The weighing method is suitable for weighing in a full-load range and can improve weighing precision; and the invention further discloses a weighing method for a variable- frequency pulsator washing machine.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a weighing method of a variable frequency pulsator washing machine. Background technique [0002] With the in-depth study of frequency conversion technology and the reduction of the cost of related power devices, frequency conversion drive technology is rapidly popularized in the field of home appliance technology. As a traditional large appliance, the washing machine has frequency conversion, and based on the frequency conversion technology, it is an inevitable trend to develop more energy-saving and efficient washing functions. [0003] In the washing machine development process, the fuzzy weighing algorithm is a classic function. The weighing algorithm is different according to the design principle. At present, a variety of high-precision algorithms are used in the product. Among them, for non-frequency conversion models, the method of cal...
