Description

The control device of intelligent box-type furniture

Technical field

The utility model relates to a kind of control device of intelligent box-type furniture of realize dehumidifying automatically mildew-resistant and sterilizing function.Belong to the automatic control technology field.

Background technology

The whole world is annual because of moist, the economic loss that is caused of going mouldy reach hundreds billion of dollars (only referring to the family aspect), stands in the breach especially and be located in the torrid zone, subtropics and coastal countries and regions.China most of area, south and coastal area all have the month of several humidities every year, the people of this area's life can suffer the plum rains in late spring, the puzzlement that the damp and hot article that bring of hot summer go mouldy, people are usually mouldy because of clothing, bed clothes, food, medicine, books go mouldy, particularly high-grade article such as camera, camera lens go mouldy and damage and worried, and almost beyond thought economic loss is all being born by each family.Therefore, how to dehumidify, mildew-resistant becomes the problem that people extremely pay close attention to naturally.The dehumidifying antimildew function of intelligent furniture produces under above-mentioned background exactly.This intellectuality cabinet class control device dehumidifies automatically by control device, makes the cabinet interior humidity always remain within the safe range, thereby effectively avoids all kinds of stored articles to go mouldy.

In recent years, because various infectious diseases human health as serious threats such as popular global SAS in 2003 and bird flus, cause people disability even death.Any infectious disease popular all must have 3 conditions, and promptly the infection sources, route of transmission and Susceptible population prevent and control all kinds of infectious disease transmissions and popular, must adopt an effective measure, and blocking-up wherein any one link can stop popular.Along with the kind and the function of public place are constantly extensive, interpersonal contacts touch opportunity in active procedure is just frequent more, and the chance of cross-infection is also many more, and the probability of taking back family is also just big more.Thus, avoid transmission by the sterilizing function blocking-up routes of infection that design intelligent box-type furniture.

The existing in the market box-type furniture with dehumidifying antimildew function is that the switch by artificial control cabinet internal moisture removal parts dehumidifies, and not only uses inconvenient, and higher to the sealing requirements of cabinet for guaranteeing effect on moisture extraction.This device designs automatic dehumidification function based on this, need not artificial interference and can guarantee that the cabinet interior humidity is moderate, thereby avoid all kinds of stored articles to go mouldy.The use uviol lamp carries out disinfection, because ultraviolet long-term irradiation can cause certain harm to human body, therefore, the control system of taking safeguard measure to design intelligent box-type furniture is closed in user's use automatically, thereby avoids ultraviolet direct irradiation human body.

Summary of the invention

The purpose of this utility model is in order to overcome the defective that existing cabinet series products can not dehumidify automatically and sterilize, a kind of control device of intelligent box-type furniture is proposed, this device is loaded on cabinet inside, not only can dehumidify automatically to reach anti-mold effect, also has the function of disinfection simultaneously.

Technical solution of the present utility model: its structure is corresponding respectively three signal input parts that connect in the single-chip microcomputer of the signal output part of humidity sensor, temperature sensor, tongue tube, the corresponding respectively signal input part that connects display circuit, driving circuit of the signal output part of single-chip microcomputer, the signal output part of driving circuit are respectively by the corresponding signal controlling end that connects uviol lamp, dehumidifier of relay.

Advantage of the present utility model: design is joined display, button, humidity measuring circuit, temperature sensing circuit, driving circuit etc. outward with the control core of single-chip microcomputer as box-type furniture.Arrive when setting disinfecting time, uviol lamp is opened, as user's use midway, uviol lamp will be closed automatically, thereby avoid ultraviolet direct irradiation human body, when disinfecting time then, uviol lamp can be closed automatically, stops sterilization, as the user special sterilization demand is arranged, can adjust the time by button, be user-friendly to greatly.Automatically dehumidification function is to utilize humidity sensor to detect humidity value, calculate by single-chip microcomputer and to judge that humidity is whether in the dehumidifying scope, if, pilot relay is opened dehumidifier and is dehumidified, if do not exist, then control dehumidifier and stop dehumidifying, reach by automatic control cabinet body interior humidity and prevent the purpose of going mouldy.

The utlity model has automatic sterilization and dehumidifying antimildew function, can dehumidify automatically, prevent that article from going mouldy, uviol lamp can regularly be sterilized, and the direct radiation human body does not play a protective role.Be user-friendly to, simple in structure, economical and practical.
