Description

Refrigerator and ultrasonic processing device thereof Technical Field The invention relates to the technical field of refrigeration and freezing, in particular to a refrigerator and an ultrasonic treatment device thereof. Background At present, ultrasonic pickling equipment is gradually favored by the vast users due to the characteristics of high pickling speed and good pickling effect. In the existing ultrasonic pickling equipment, the transducer is usually directly fixed at the bottom of a container, more heat is generated by the transducer during working, so that the surface of an inner food material is cured because the heat is concentrated to the bottom of the container, the transducer needs to be controlled to be alternately started and stopped according to a set starting ratio in the use process, and therefore the transducer is cooled in time, but the total duration of pickling the food material is long and still needs to be improved. Disclosure of Invention An object of the first aspect of the present invention is to utilize a self-cooling medium with a good heat absorption effect to timely absorb heat generated by an ultrasonic transducer, so as to greatly reduce the temperature rising speed of a container during the operation of the ultrasonic transducer. A further object of the first aspect of the invention is to provide for a reasonable setting of the filling level and filling height of the self-cooling medium according to the number of ultrasonic transducers. An object of a second aspect of the present invention is to provide a refrigerator. In particular, according to a first aspect of the present invention, there is provided an ultrasonic treatment apparatus comprising: a container for holding food material to be treated; at least one ultrasonic transducer arranged outside the bottom wall of the container, and A base defining an upwardly facing opening for placement of a container therein; when the container is placed in the base, an interlayer space for accommodating the ultrasonic transducer is formed between the bottom wall of the container and the bottom wall of the base, self-cooling medium is filled in the interlayer space and used for absorbing heat generated by the ultrasonic transducer in the working process of the ultrasonic transducer. Optionally, a gap is left between the side wall of the container and the side wall of the base, the self-cooling medium being configured such that its filling height exceeds at least the bottom wall of the container. Optionally, a bottom wall of the container is formed with a positioning groove protruding toward the inside of the container, and the ultrasonic transducer is mounted into the positioning groove. Optionally, the shape of the positioning groove is matched with the shape of the ultrasonic transducer, the top wall of the ultrasonic transducer is fixedly bonded with the top wall of the positioning groove, and the side wall of the ultrasonic transducer is fixedly bonded with the side wall of the positioning groove. Optionally, the charge and charge height of the self-cooling medium is positively correlated to the number of ultrasonic transducers. Alternatively, the number of ultrasonic transducers is three, and the three ultrasonic transducers are fixed to the outside of the bottom wall of the container at equal intervals along the length direction of the container. Optionally, the self-cooling medium is a cold storage liquid or a cold storage gel. Optionally, the ultrasonic processing apparatus further includes: and the upper cover is buckled on the container in a removable way. Optionally, a handle is arranged at the top of the upper cover, and the weight of the handle is configured to enable the upper cover to be sealed and buckled on the container all the time in the process that the ultrasonic transducer drives the container to vibrate. According to a second aspect of the present invention there is provided a refrigerator comprising a cabinet defining a storage compartment therein, the storage compartment being provided with any one of the above-mentioned ultrasonic treatment devices. In the ultrasonic treatment device, a container is placed in a base in a removable way, an interlayer space for accommodating an ultrasonic transducer is formed between the container and the base, and self-cooling medium is filled in the interlayer space. In the working process of the ultrasonic transducer, the self-cooling medium can absorb heat generated by the ultrasonic transducer relatively quickly, heat transfer to the container is reduced, and the heating speed of the container is delayed, so that a user can properly increase the starting-up ratio of the ultrasonic transducer, and further the total time required for pickling food materials is shortened. In addition, the self-cooling medium can directly radiate heat of the ultrasonic transducer, so that the ultrasonic transducer can be effectively prevented from being overheated and damaged in the wor
