Description

{FOOD DEHYDRATOR FOR FAMILY USE}

The present invention relates to a food drier, and more particularly, to a drying device that optimizes and uniformizes a hot air circulation function to minimize a temperature deviation between trays containing a drying object, thereby significantly improving drying efficiency, The present invention relates to a household food drier which can be easily and easily used.

In recent years, food dryers have become popular as well-being appliances that can be conveniently used for snack foods and food materials by easily drying various foods such as fruits and vegetables (hereinafter referred to as " dried food " .

Particularly, a fan and an air heater are installed in a cabinet so that hot air can be contacted and circulated horizontally or vertically between trays containing the articles to be dried to thereby evaporate the moisture of the articles to be dried. A vertical stacking type in which a plurality of trays (vertically stacked vertically) are vertically stacked on the upper side of a base provided with a cabinet dryer, a fan and an air heater, The dryer is the mainstream.

For example, as shown in FIG. 1, the food drier disclosed in Korean Utility Model Registration No. 20-0354535 has a structure in which outside air is sucked through the inlet port 4-1 by the rotation of the fan 15, And the heated air is sequentially blown upward through the net plate 11 of the drying bed in which the bed layers are piled up, drying the laundry, and then moving downward through the central through hole 9 ' And then flows again into the heater 12 through the circulation hole 9 to be heated and circulated again and a small amount of air is exhausted to the outside through the exhaust port 4 by natural convection .

For example, as shown in FIG. 2, the food drier disclosed in Korean Patent Publication No. 10-1446071 includes a drying stand 20 in which the heat of the heater 11 is blown out by hot air by a blowing fan 12 and stacked in multi- And then flows downward through the through passage 33a formed in the ventilation hole 33 of the lid body 31 and flows into the blower case 13 again and at the same time, And external air is introduced through the through-hole 33c formed in the upper part.

Such conventional food driers have a structure in which hot air is repeatedly circulated in order to uniformly transfer heated air (hot air) to the drying object, and most of the heat retained is used to raise the temperature of the drying object and to evaporate water, It is fast, uniform, and has little energy loss.

However, this is due to the fact that due to the structural characteristics of hot air being conveyed from the lower part to the upper part and the drying part being stacked in multiple stages, there is a temperature variation between the drying part, and the drying condition of the upper part of the laundry is lower than that of the lower part, And because most of the hot air except heat loss is not discharged, in the early stage of the drying process, the amount of moisture that evaporates from the drying object is considerably low, so that fogging and water droplets are formed in the interior. In this case, Water and water droplets fall down by their own weight, polluting the dried body, and if it is collected over a certain amount, it becomes not only hygroscopically and visually dirty, but also it is difficult to maintain a constant state in which the internal environment becomes hot and humid and the drying is properly performed. As a result, Or twist and twist There is a problem that the quality is low.

In the household food drier disclosed in Korean Patent Publication No. 10-1283516, as shown in FIG. 3, the door door 15 is opened to form a plurality of catching guides 12 on both sides of the drying chamber 10, And the air is heated by supplying the air to the drying chamber 10 through the air blowing fan 31 to dry the object to be dried contained in the tray 20 by heating the air by operating the electric heater 32 provided on the upper part of the drying chamber 10, .

Since the drying chamber 10, the electrothermal heater 32 and the blowing fan 31 are integrally formed in the outer case 13, if the inside of the drying chamber 10 is contaminated, it is very difficult and difficult to clean the inside of the drying chamber 10 There is a limit of useless usage.

The operation and operation of the food drier according to the embodiment of the present invention will be described with reference to FIG.

First, the laundry 500 is put on or placed on the tray 500, and the tray 500 is stacked on the tray 433 in the tray container 400 at a predetermined height according to the size, thickness and quantity of the laundry, The duct 600 is inserted into the upper and lower mounting holes 421 and 411 of the tray container and then the door 440 is closed so that the control unit 240 is operated and set in this state to connect the heater blower assembly The heater blower assembly 100 forcibly blows outside air through the air inlet 610 of the duct and the air inlet 111 of the cap to convert the air into hot air and then through the air outlet 112 of the cap And is strongly ejected into the upper tray container 400.

In this case, the hot air is moved upward by the convection phenomenon to dry the laundry contained in the tray 500 stored in the tray container 400, and at the same time, a part of the hot air is formed on both sides of the tray container 400 And is discharged to the outside through the air outlet 422. At this time, the hot air in the tray container 400 is pushed back to the duct 600 and the suction port 111 of the cap through the air circulation hole 620 of the duct 600 due to a pressure difference or the like, And is ejected into the upper tray container 400 through the jet port 112 of the cap.

In this process, moisture evaporated from the laundry is naturally discharged to the air discharge port 422 or sucked into the heater blower assembly 100 through some ducts 600 and heated and dried. Therefore, moisture inside the tray container 400 It is possible to minimize the occurrence of fogging and water droplet condensation.

That is, through the air circulation openings 620 having different sizes of the ducts 600, the hot air flows smoothly and uniformly without stagnation, minimizing the temperature variation between the trays 500 and evaporating the moisture in the hot air and the laundry It is possible to more effectively remove moisture and significantly improve the drying efficiency of the laundry.

In addition, the upper side hot air, which is relatively low in temperature due to the temperature difference among the hot air circulated in the tray container 400, is heated through the upper air circulation hole 620, At the same time, the hot air located in the front surface of the tray container 400 is quickly sucked and vented, so that the temperature difference between the top, bottom, front and side surfaces of the tray container is minimized when the laundry is dried It is possible to prevent the occurrence of fogging on the transparent window 441 of the door and to prevent the object to be dried contained in the tray 500 located in the lower portion of the tray container 400 from being discolored or deformed due to premature drying .

Further, since the water generated in the drying process of the laundry dries naturally along the bottom inclined surface of the base 200 and is collected in the drain pan 300 of the outside through the drain hole 220, it is easy and easy to remove the water The drying efficiency can be greatly improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments or constructions. Various changes and substitutions may be made without departing from the spirit and scope of the invention. It will be obvious to those skilled in the art that the present invention can be widely applied to other embodiments.
