    • A dishwasher including a variable spray device operable to spray a liquid into a washing container of the dishwasher, the variable spray device, and a method thereof. The variable spray device may be structured to include a chamber for receiving the liquid therein, such as a dishwashing liquid or water, and a liquid deflector disposed in the chamber. The liquid deflector may have a geometrically shaped perimeter, for example, a conical shape, that allows for the generation of a centrifugal force within the chamber used in directing the spray of the liquid into the washing container. By varying a force or pressure of the liquid as it interacts with the liquid deflector in the chamber, variable spray patterns may be generated.
    • 一种洗碗机,包括可操作以将液体喷射到洗碗机的洗涤容器中的可变喷雾装置,可变喷雾装置及其方法。 可变喷雾装置可以构造成包括用于容纳其中的液体的腔室,例如餐具洗涤液体或水,以及设置在腔室中的液体偏转器。 液体导流器可以具有几何形状的周边,例如圆锥形,其允许在用于将液体喷射到洗涤容器中的室内产生离心力。 通过在室中与液体偏转器相互作用时改变液体的力或压力,可能产生可变的喷雾图案。

    • Circuits and methods for a switched power converter providing charge power for at least one battery and at the same time delivering current to operate an electronic device, wherein the converter is enabled to operate out of current limit mode, for the maximum possible range of system load requirements, have been achieved. The input current of the power converter is measured within each cycle-by-cycle, i.e. within each cycle of an external clock reference and the charge current is reduced if the input current exceeds a defined portion, e.g. 80% of the maximum allowable input current. The power converter may only enter current limited operation after the charge current has been already reduced to zero. Operating out of current limit mode ensures a maximum efficiency of the converter, maximize the current deliverable to a given load and minimizes subharmonics in the output current and voltage, thereby minimizing interference with other system component.
    • 用于为至少一个电池提供充电电力并且同时传送电流以操作电子设备的开关电力转换器的电路和方法,其中所述转换器能够在限流模式下操作,以实现系统负载的最大可能范围 要求已经实现。 功率转换器的输入电流在逐周期内,即在外部时钟参考的每个周期内测量,并且如果输入电流超过限定部分,则充电电流减小。 80%的最大允许输入电流。 功率转换器只能在充电电流已经降到零之后才进入电流限制运行。 超出电流限制模式的运行确保了转换器的最大效率,最大限度地提高给定负载的电流,并最大限度地减少输出电流和电压中的次谐波,从而最大限度地减少与其他系统组件的干扰。
