Refrigerator with function expansion interfaces

Abstract

The invention relates to a refrigerator with function expansion interfaces. The refrigerator comprises the function expansion interfaces used for being connected with external devices. The function expansion interfaces comprise any one or more of structural interfaces, signal interfaces and power interfaces. The external devices are fixedly connected to the refrigerator through the structural interfaces. The signal interfaces transmit a control signal of a micro-control unit of the refrigerator to the external devices. The power interfaces provide current needed during work for the external devices. The external devices are one or more independent parts with refrigerator expansion functions, the external devices connected with the function expansion interfaces can achieve respective functions in the refrigerator, and the external devices comprise a humidifying device, a sterilizing device, a deodorizing device, an odor pre-warning device, a temperature and humidity adjustor, an automatic ice maker, a state detector, a food making device and the like. According to the refrigerator, due to the function expansion interfaces, the external devices with the specific functions are connected to the interior of the refrigerator, the respective functions of the external devices are played, and therefore the pers onalized requirements of users can be met.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator with a function expansion interface. Background technique [0002] When consumers buy refrigerators, due to cost or technical constraints, they cannot buy some ideal models. For example, a fruit wholesaler wants to buy a refrigerator with humidification function, which can keep fruits fresh for a long time, but it has this function The price of refrigerators is more than 6,000 yuan, 4,000 yuan more than his own budget, so he has to choose a refrigerator without this function; a user’s refrigerator has been used for 6 years, and he feels that the interior of the refrigerator needs to be repaired after long-term use. Sterilization, but the refrigerator did not have the sterilization function when it was purchased back then, and it cannot be upgraded now. Unless you buy a refrigerator with the sterilization function again, you can only continue to use the old refrigerator...

AI Technical Summary

Problems solved by technology

However, there are limitations to the existing configuration of the refrigerator and the integrated combination of modules, which cannot meet the needs of users for personalized expansion functions, and the overall system of the refrigerator is very complicated and the cost is high
