Automatic detergent adding device and washing machine

Abstract

The invention discloses an automatic detergent adding device and a washing machine. The automatic detergent adding device comprises a box body, a piston arranged in the box body, a storage box and a controller, wherein the piston divides the interior of the box body into a detergent containing chamber and a water containing chamber, the bottom of the water containing chamber is communicated with awater inlet-outlet pipe, a first valve is arranged on the water inlet-outlet pipe, a liquid outlet is formed in the wall of the detergent containing chamber, a liquid inlet is formed in the wall of the detergent containing chamber, and the storage box is communicated with the liquid inlet by a liquid supplementing pipe; a second valve is arranged on the liquid supplementing pipe, a third valve isarranged at the liquid outlet, and the water inlet-outlet pipe is connected with a bidirectional pump; a sensor is arranged in the detergent containing chamber, so as to detect the dynamic capacity of the detergent containing chamber; and the controller controls the actions of the first valve, the second valve, the third valve and the bidirectional pump according to the dynamic capacity. The storage box is arranged outside to reduce the size / volume of the box body, and the device has relatively high sensitivity, and thus being favorable for realizing accurate control on the detergent adding amount, alleviating the load of the washing machine, providing better intelligent assistance to the washing machine and enhancing the user experience.

Description

technical field [0001] The present application relates to the technical field of smart home, in particular to an automatic detergent adding device and a washing machine. Background technique [0002] Traditional washing machines require users to manually inject detergent before washing clothes each time. This method is not only inefficient, but also cannot accurately control the amount of detergent injected. In this regard, modern smart washing machines are usually equipped with a detergent adding device, which is used to automatically add a required flow of detergent into the washing machine barrel according to the weight / volume of the laundry to be washed, which significantly improves the user experience. [0003] figure 1 The structure of a detergent adding device is specifically shown, including a storage box 11, a piston 14 is arranged inside the storage box 11, and the internal space of the storage box 11 is divided by the piston 14 into a detergent chamber 12 and a w...
