Abstract <br>With the modern society smart home is the first choice for young people, the popularization of the Internet of Things technology, the seemingly tall concept of smart home life gradually spread to people ’s daily life, in order to meet the needs of young people, reduce the lives of young people pressure. With the acceleration of life rhythm, the lives of many young people are gradually moving toward 996. The quality of home life in the busy work is inevitably unable to keep up. When the weather is bad, folding clothes and drying anti-virus have become many young people. The headache is that there are a lot of household equipment that can be completed (folded clothes drying and disinfection) in the market, either expensive or not fully functional. This article is mainly designed for drying and disinfection of stacked clothes, not taking up domestic space. The main contents are as follows: <br>part of the design of the <br>drying anti-virus device. The drying device uses a heater to measure the temperature through a thermocouple, and the touch screen is used to adjust the temperature and heat. The speed is fast, and the drying temperature can be changed at will. The fan blows the heat generated by the thermocouple into the inside of the chassis, so that the hot air flows quickly in the chassis to achieve the drying effect. The principle of ultraviolet sterilization is used, so an ultraviolet sterilization lamp is selected in the case, and disinfection is performed at the same time when drying. In order to avoid incidents such as ultraviolet rays or thermocouple injury, proximity sensors are added to the doors on both sides. When the device is working, if one of the doors is opened, it will quickly stop all procedures (for example, the thermocouple stops heating, The fan stops rotating and the ultraviolet disinfection lamp goes out), and enters the stop state. <br>Folding device part design The <br>folding device adopts two stepping motors and synchronous wheels to drive the two left and right folding plates to complete part of the folding. With the photoelectric switch to achieve precise positioning, the stepping motor can not lose steps due to changing the direction. After completing 10 times C / T, the stepper motor cooperates with the photoelectric switch to return to the origin once, to avoid the cumulative loss of steps due to repeated movements. <br>Design of lifting and folding device<br>The lifting and folding device uses a stepper motor, a synchronous wheel, a synchronous belt, an engineering plastic slide rail, a photoelectric switch, etc. As the lifting mechanism, the synchronous belt drives the lifting platform to move up and down, so as to achieve the purpose of lifting. Using the principle of photoelectric induction, the lifting platform can be stopped at the position where there is a sensor. The folding part adopts a tension spring (single tension is not less than 1KG). When the lifting platform is lowered to the position of the sensor, the front and rear folding plates come into contact with the shield. Due to the spring tension, the folding plate is angularly displaced after being pulled, so as to achieve stacking Clothing effect. <br>The design of drying and stacking control is <br>aimed at drying, disinfection and stacking, etc., using plc control, combined with equipment control needs, according to the PLC pulse output control program, completed the programming of the household baking and stacking machine, the designed program functions are : Speed ​​control, temperature control, speed design of drying and disinfection time, etc. <br>The household baking and stacking machine designed this time can complete the functions of stacking clothes, drying and anti-virus according to the theory, which basically meets the requirements of this design. <br>Keywords: folding clothes, drying, control system.

Summary<br>With the modern society smart home is the first choice of young people, the popularity of Internet of Things technology, smart home life, this seemingly tall concept gradually popularized into people's daily life, in order to meet the needs of young people, reduce the pressure in young people's lives. With the acceleration of the pace of life, many young people's lives gradually towards 996, in the busy work of the quality of home life inevitably can not keep up, when the weather is bad, laminated clothes, drying anti-virus has become a headache for many young people, the market can complete (stacking and disinfection) of household equipment has a lot, either expensive, or not complete function.

The folding part uses the stretch spring (a single pull is not less than 1KG) when the lifting platform drops to the sensor position, the front and rear folding plate is in contact with the guard, because of the spring pull, the pull after the folding plate has an angle shift, thus achieving the effect of folding up and down.<br>Drying and laminating control design<br>For drying disinfection and folding, etc. , the use of plc control, combined with equipment control requirements, according to PLC pulse output control program, completed the home baking machine programming, designed program functions are: speed control, temperature control, drying disinfection time fast and slow design.<br>This design of the home baking machine, according to the theory can complete the folding, drying anti-virus and other functions, basically meet the design requirements.<br>Keywords: folding, drying, control system.

abstract<br>With the popularity of Internet of things technology, smart home is the first choice of young people in modern society, and the seemingly tall concept of smart home life is gradually popularized in people's daily life. In order to meet the needs of young people and reduce the pressure in their lives. With the acceleration of the pace of life, many young people's life gradually goes to 996. In the busy work, the quality of life at home cannot be kept up with. When the weather is bad, folding clothes, drying and detoxification have become a headache for many young people. There are many household equipment in the market that can complete (folding clothes, drying and disinfection), which are either expensive or not fully functional. In this paper, folding drying and disinfection are mainly used in the design, which does not occupy the domestic space. The main contents are as follows:<br>Part design of drying and antivirus device<br>The drying device uses the heater to measure the temperature through the thermocouple, and the touch screen to adjust the temperature.

Using the principle of ultraviolet disinfection, the ultraviolet disinfection lamp is installed in the case. When drying, the disinfection treatment is carried out at the same time. In order to avoid the occurrence of UV or electric couple injury and other events, so add proximity sensors at the doors on both sides.

For the folding part, the tension spring (single tension is not less than 1kg) is used. When the lifting platform is lowered to the sensor position, the front and rear folding plates contact with the shield. Due to the existence of spring tension, the angle displacement occurs when the rear folding plate is pulled, so as to achieve the effect of upper and lower folding.<br>Drying and stacking control design<br>In view of drying, disinfection and folding clothes, PLC control is adopted, combined with the equipment control requirements, according to the pulse output control scheme of PLC, the program of household drying and folding machine is completed.
