In the present invention, as a design technology for a house without a kitchen, it is a design technology for replacing a house with a structure that does not cook like a hotel, and replaces the function of the kitchen with an external third-party service. This service is a smartphone-based online-to-offline (O2O) food delivery service. It is an IoT-based delivery tube that provides maximum convenience through unmanned automation of the process of delivering food from outside the house to inside the house. It is to equip facilities. Through this, food delivery service, laundry service, and various courier services are automatically unmanned to maximize convenience. This is to make expensive services, such as hotel room service and laundry service, popularized by lowering cost-effectiveness through wireless Internet and Internet of Things technology and sharing economy model. The effect obtained through the present invention is, first, by removing the kitchen, all kitchen appliances and kitchen space related to the kitchen are eliminated, thereby reducing the space cost through the space saved or obtaining a wider living space. The benefits from this can be much more economical. This will provide a spatial benefit of 10-20% of the entire house and 40-50% of the living space. Especially in the situation where the number of households living alone or only married couples is increasing, the effect of space saving due to kitchen removal will be greater for small houses for them. In addition, by removing the kitchen, all kitchen-related appliances and household appliances are unnecessary, thereby reducing the cost of construction, installation, and purchase to provide it. In other words, it is possible to reduce the cost of construction and in the case of newlyweds, the cost of preparing the initial salary. Eliminating the kitchen can dramatically reduce the burden of housework. In other words, there is a lot of housework involved in cooking, washing dishes, handling leftovers, purchasing and storing ingredients, cleaning kitchens, and managing hygiene. If most of the housewives are in charge of housework, removing the kitchen will free the housewives from the core housework stress and realize gender equality at home. In particular, it will be more effective in the case of living alone, newlyweds, working couples, and elderly couples. Finally, in the present invention, the core function of eating at home is replaced with the concept of a service that can be provided from outside, not the kitchen. A key design concept that makes this possible is the delivery tube facility installed on the veranda. This is by incorporating mobile Internet services and IoT technologies such as RFID into automatic facilities to innovatively increase automation functions, maximizing customer convenience through technology so that they can be provided at almost hotel room service levels. Furthermore, if such a service is expanded to a laundry service, all the spaces related to clothes and washing machines, such as wardrobes, and washing machines are eliminated. Convenience through the delivery tube equipment proposed in the present invention may be maximized.
