Based on the above problems, an external microbubble generating device is needed to assist in washing.

[0029] Moreover, in the related art, the microbubble generating device is applied to the washing machine without using bubble stones; the water ejector is composed of three parts: a nozzle, a suction chamber, and a diffuser. Bubbles are generated by changing the aperture, which affects the inlet water flow pressure, and the amount of microbubbles is relatively small.

[0030] In order to solve the problem of the technical solution of the micro-bubble generating device in the related art, the utility model proposes a micro-bubble generating device and a washing machine, the main idea of ​​which is: there are many micro-pores on the bubble stone, the bubble stone is placed in the water body, and the air is blown by an air pump or a blower, and the gas enters the bubble stone through the ventilation hose, generating micro-porous bubbles in the water, and the bubbles dissolve in the water, so as to improve the dissolution rate of the detergent, and then improve the washing rate of the clothes.

Since the microbubbles can be generated without using a water ejector, the water inlet pressure is not affected, which solves the problem that the microbubble generating device of the existing washing machine mainly uses the water ejector principle to generate microbubbles, which is easy to affect the water inlet pressure.

[0041] Furthermore, in the embodiment of the utility model, the air pump 10 and the air stone assembly 7 are made into an external integrated external device, which is convenient for the maintenance and replacement of the air pump 10 and the air stone assembly 7, and the user can choose whether to install them according to the needs.
