Description

Large refrigerator for storing large quantities of goods and saving energy {Large refrigerator with a great deal of goods and energy savings}

The present invention relates to a large-sized refrigerator that stores large quantities of items and saves energy. Specifically, basket-type and panel-type shelves are installed on the inside of the heat-radiating door and the front and rear panels of the refrigerator to store a large amount of items (food, etc.). In addition, as the air flows out and flows into the air pockets that contract and expand according to the temperature of the internal air as the refrigerator operates, it does not mix with the air inside the refrigerator, reducing power consumption and preventing the quality of stored items from deteriorating. It is configured to do so.

In general, a refrigerator is a home appliance designed to store food at low temperatures in an internal storage space shielded by a door. It cools the inside using cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle to optimally store stored food. It is configured so that it can be done in this state.

In order to efficiently use the space of the refrigerator, such a refrigerator is equipped with multiple shelves for storing items inside the refrigerator and on the refrigerator door. This is mounted on a bead formed inside the refrigerator or on a bracket provided on the back side. It can be installed and placed efficiently to carry a large amount of goods.

In these refrigerators, the volume of the internal gas is usually adjusted according to the rate of temperature change according to Boylechar's law (all gases increase or decrease in volume in response to changes in temperature, and a volume change of 1/273 occurs for every 1°C change in temperature). There is a difference: when the gas is heated, it flows out of the refrigerator, and when it cools, the outside air flows into the refrigerator.

In this way, the inflow and outflow of gas acts as a load on the refrigerator, which causes effects such as an increase in the operating time of the refrigerator, an increase in power consumption, an inflow of external moisture, and an outflow of moisture inside the refrigerator, which increases power consumption and is detrimental to internal storage items. It will lead to an undesirable action.

Prior art for such a refrigerator is provided in Patent Publication No. 10-2012-0005787 (title of the invention: Variable assembly shelf for large refrigerator).

The variable assembly tip for a large refrigerator in the prior art includes a vertical fixture whose lower part is fixed to the floor panel of the large refrigerator and has a plurality of first vertical guide grooves formed thereon; a vertical movable stand having a movable lower part of the floor panel corresponding to the vertical fixture and having a second vertical guide groove formed to correspond to the first vertical guide groove; Front and rear reinforcement bars fastened to the floor panel between the vertical fixture and the vertical movable band; A shelf frame consisting of a top plate detachably fastened to the upper part of the vertical fixing table, the vertical moving table, and the front and rear reinforcement bars; and a plurality of storage racks between the shelf frames that can be moved up and down using a moving means, and whose up and down moving positions are maintained by a locking means, and on which stored goods are placed.

The prior art constructed in this way is convenient because the storage rack can be moved up and down using wires and pulleys, the storage rack can be expanded and contracted within the length range depending on the purpose of use, and the gap between shelf layers can be adjusted, making space utilization easy. The effect is provided.

However, this prior art uses wires connected and supported between the front and rear frames to move the storage unit up and down or adjust its length, making it easy to utilize space horizontally, but utilize space vertically, that is, on the wall side. Not only is it not easy to use as the user has to pull the wire and move it, but its use is limited as it can be applied to stored items that generate a lot of weight. Additionally, when the refrigerator is in operation, boilshar According to the difference in the rate of temperature change according to the law (all gases increase or decrease in volume in response to changes in temperature, and a volume change of 1/273 occurs for every 1°C change in temperature), when the gas is heated, it flows out of the refrigerator. Due to the load acting as an inflow and outflow of gas that flows into the refrigerator when cooling, external air flows into the refrigerator, resulting in effects such as an increase in refrigerator operation time, increased power consumption, inflow of external moisture, and outflow of moisture inside the refrigerator. This has the problem of increasing power consumption and adversely affecting internally stored items.
