Description

A refrigerator drawer that automatically stores food

technical field

The invention belongs to the technical field of refrigerators, and relates to a refrigerator drawer for automatically storing food.

Background technique

Existing refrigeration technology can only be stored in the refrigerator under the refrigerated normal temperature state. The food with high temperature cannot be put into the refrigerator immediately. Food is not good. Through investigation, it is found that in many cases, users are eager to put hot food into the refrigerator when using the refrigerator, and the prior art cannot meet this demand, and the present invention solves this demand.

Contents of the invention

The object of the present invention is to provide a refrigerator drawer for automatically storing food. Solved the problem that hot food cannot be refrigerated when users are in a hurry.

The technical scheme adopted in the present invention is to set a small drawer on the refrigerator drawer; the small drawer is located in the refrigerator drawer, and can draw out a part from the refrigerator drawer. Not connected to each other.

Further, the inside of the small drawer is provided with a temperature sensing module, the temperature sensing module is connected to the PLC control module, the outer surface of the small drawer is inlaid with a touch switch, the touch switch is connected to the PLC control module, and the PLC control module is connected to the micro motor through the motor drive module , the rotating shaft of the miniature motor is connected to control the operation of the wheels installed at the bottom of the small drawer.

Further, the refrigerator drawer is a middle refrigerator drawer.

The beneficial effect of the invention is that the food can be placed in the open small drawer in advance when it is hot, and the intelligent drawer automatically senses the temperature of the food, and is automatically stored in the refrigerator when the temperature reaches room temperature.

detailed description

The present invention will be described in detail below in combination with specific embodiments.

In the present invention, as shown in Figures 1 to 3, a small drawer 2 is arranged on the refrigerator drawer 1; the small drawer 2 is located in the refrigerator drawer 1, and can extract a part from the refrigerator drawer 1. After the maximum limit, the small drawer 2 and the refrigerator drawer 1 are not connected to each other;

As shown in Figure 4, the small drawer 2 is provided with a temperature sensing module 3 inside, the temperature sensing module 3 is connected to the PLC control module 4, the outer surface of the small drawer 2 is inlaid with a touch switch 5, and the touch switch 5 is connected to the PLC control module 4, The PLC control module 4 is connected to the micromotor 7 through the motor drive module 6, and the rotating shaft of the micromotor 7 is connected to control the operation of the wheels installed at the bottom of the small drawer 2.

When in use, touch the touch switch 5 with your finger, and the touch switch 5 sends a signal to the PLC control module 4, and the PLC control module 4 drives the micro motor 7 to rotate through the motor drive module 6, so that the small drawer 2 pops up, and the hot food 1. After the container is put into the small drawer, people can leave. The temperature sensing module 3 measures the internal temperature of the small drawer 2, and when the temperature reaches a preset value, the PLC control module 4 controls the operation of the motor drive module 6, so that the small drawer 2 automatically retracts into the refrigerator drawer 1, its exterior and the exterior of the refrigerator drawer 1 become a flat whole.

The wheel at the bottom of the small drawer 2 is controlled by a micromotor 7. The small drawer 2 is a drawer embedded in the refrigerator drawer 1 .

When the refrigerator drawer 1 is opened, the small drawer 2 can be pulled out together, and the refrigerator drawer 1 does not move when the small drawer 2 is opened independently.

Since the space for refrigerating hot food generally does not need much, it can generally accommodate a large soup bowl, and the remaining space of the large drawer can be used to refrigerate other foods to effectively use the excess space. When the large drawer is drawn out, a large amount of energy will be lost during the food cooling time, resulting in waste. In the present invention, the small drawer 2 is embedded in the large drawer, and the surroundings are closed when it is drawn out, thereby reducing the loss of cooling capacity and satisfying the need for instant storage of hot food and refrigeration problem.

The invention also has the advantage that the food can be placed in the open small drawer in advance when it is hot, and the smart drawer automatically senses the temperature of the food and automatically stores it in the refrigerator when the temperature reaches room temperature. It solves the problem of refrigerator users' hot food storage refrigerators, brings great convenience to users, meets user needs, and brings new economic growth points for refrigerator enterprises.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modifications made to the above embodiments according to the technical essence of the present invention, equivalent changes and modifications, all belong to this invention. within the scope of the technical solution of the invention.
