Description

The proposed utility model relates to the field of refrigeration technology and can be used to receive and store goods ordered by the consumer via the Internet, mainly grocery goods.

Currently, ordering services with the delivery of goods via the Internet are becoming widespread.

Usually, the ordered goods are delivered by couriers at the agreed date and time. In this case, as a rule, the presence of the consumer who accepts the order is required to receive the goods, which is often an inconvenient and complicated procedure for both the consumer and the seller. In addition, if the products are stored and left, for example, near the front door of the consumer, then the problem arises of their safety in the absence of the temperature regime required for the products.

The delivered products are then placed in the refrigerator by the consumer, which takes additional time for the consumer.

In order to make the delivery of goods more convenient and to ensure the required temperature regime for storing delivered products, the well-known American retailer Walmart offers the delivery of ordered grocery goods "to the refrigerator" (https://e-pepper.ru/news/walmart-zapustil-dostavku -v-kholodilnik.html).

Technically, such a service is carried out by installing "smart" door or garage locks on the user's entrance or garage door. Couriers who receive a delivery order pick up boxes of groceries at a warehouse or store, drive to the outlet, and then enter the consumer's homes themselves using a one-time access code, which can only be activated if the camera captures an employee dressed in uniform. Upon entering the house, the courier places the food in the refrigerator.

In this case, it is possible to use any household refrigerator.

The described service, from the point of view of logistics, is more convenient than the delivery of goods directly into the hands of the consumer.

However, if a stranger enters the house, it is difficult to guarantee the safety of the home. At the same time, additional measures are required from the seller to check and train the couriers who carry out such delivery, and / or install video surveillance, which makes such a service more expensive.

In addition, the penetration of a stranger into the house and access to the consumer's refrigerator can often be undesirable for the consumer for various reasons, including from the point of view of hygiene, both of the home itself and of the contents of the refrigerator.

The closest to the proposed solution is the Built-in refrigerator according to RU patent No. 2235952.

The built-in refrigerator known from the said patent is designed to be built into the partition of the room, so that its rear wall can be located on the outside of the building in which the refrigerator is located, in particular to go outside (outside). The condenser of the refrigerator is divided into two parts, which are attached to the side walls of the refrigerator cabinet. The back wall of the refrigerator is made of two-layer heat-insulated with holes, which are closed in the initial position. When the inner and outer layers of the rear wall are displaced, the holes in them are aligned, thereby communicating the working chamber of the refrigerator to the atmosphere. All chambers of the refrigerator with open holes on the back wall are covered from the outside with a protective wall.

The refrigerator cabinet is built into the wall of the kitchen in such a way that its door is flush with the wall in the kitchen, and most of the cabinet faces the street.

During summer, the openings on the rear wall are closed and the refrigerator works as usual.

In winter, the rear wall openings are automatically opened or closed using a special actuator on a command issued by temperature sensors, depending on the ambient temperature and the temperature in the chamber. When the holes on the rear wall are aligned, the resulting windows (holes) connect the camera to the atmosphere.

The outer layer of the rear wall is fixed and covered with a protective grill to protect the contents in the chamber from snow, birds and various insects. At an ambient temperature below -6 ° C, the refrigerator unit is automatically disconnected from the electrical network, openings on the rear wall of the cabinet are opened and the products placed in it are cooled by the natural cold of the environment.

In the known solution, the openings on the rear wall of the refrigerator, communicating with the external environment, are designed to save electricity consumed by the refrigerator in winter.

At the same time, the described refrigerator, when used in the courier delivery service described above, does not eliminate the problem of unwanted access of an outsider (courier) to the house, in which it is difficult to guarantee the safety of the home and, accordingly, additional measures are required from the seller to check and train couriers. carrying out such delivery, and / or installation of video surveillance, which makes such a service more expensive.

In addition, the penetration of a stranger into the house and access to the consumer's refrigerator can often be undesirable for the consumer for various reasons, including from the point of view of hygiene, both of the home itself and of the contents of the refrigerator.

The basis of this utility model is the task of creating such a built-in refrigerator that would allow for the contactless reception and storage of products delivered to order, providing the courier access to the internal chambers of the refrigerator, without the courier entering the inside of a private area, in particular, into a living room or garage. ...

The presence of a second, additional door on the opposite wall of the refrigerator provides access to the refrigerator chambers from two opposite sides.

At the same time, the possibility of embedding the refrigerator into an external partition, for example, into the wall of a house, apartment (for example, into a wall communicating with a staircase) or a fence provides access to the refrigerator chambers from the side of a public space, without the courier entering a private area: a house, an apartment, yard, etc.

The presence of locks on the first and opposite second doors, made with the possibility of blocking the first door in the closed position when the second door is in the open position, protects against unauthorized access to a private area: a house, apartment, yard, etc., when the courier is allowed access to the refrigerator chambers.

It is advisable that each lock is designed as a programmable coded electronic lock.

The use of a "smart" lock on the doors allows the courier to provide one-time access to the refrigerator chamber upon special request.

It is advisable that at least one chamber be equipped with an air disinfection device, while at least one lock on the door is configured to lock at least the first door in the closed state for a given time of operation of the disinfection device, while the specified disinfection device is made with the possibility of automatic activation after closing the second door.

The presence of air disinfection devices in the refrigerator chamber allows for the disinfection of goods delivered and loaded into the refrigerator by courier. The presence of a blocking device for the first door (a door to which the consumer has access) and a means for switching on the air disinfection device ensures the necessary disinfection of the delivered goods.
