The present invention relates to an airplane cooler according to the preamble of claim 1.

5

Trolleys (wheeled trolleys) made of aluminum (most recently Trolley) are the most often used for storing and distributing airplane moons and drinks. Trolleys are sized to international standards and are well known in size.

10 The mocha and beverage portions inside Trolley are most often cooled with carbonated ice cubes / plates. As a refrigerant, carbonated ice is a very effective but uneven and environmentally friendly substance.

Carbonic ice or "dry ice" emits 530 L / kg of carbon dioxide.

Carbon dioxide is one of the most significant waste products of mankind. The increase in the greenhouse effect 15 is very much influenced specifically by carbon dioxide.

The object of the invention is to eliminate the problems related to the cooling of food and beverages, as well as the uneven cooling and to minimize the utilization of carbonated ice as a refrigerant.

20: The airplane cooler is designed to fit inside the trolleys • · *:: *: and has a built-in cooler designed to extend the transport and serving time of cold food and beverages.

The food serving temperature should be below + 8 ° C at the time of serving. The size of the radiator is suitable for commercially available serving trolleys of the KSSU standard used by most airlines, as well as KSSU storage cabinets. It is possible to place 1 to 2: V: refrigerated containers inside the Trolley, depending on the purpose. The KSSU storage cabinet can hold 1 cooler. The radiator fits snugly inside the trolley or cabinet.

30 This will extend the life of the radiator by preventing it from moving in the wagon or. ···. inside the cupboard. Maximizing the storage space is also accomplished in this way.

* · * *. The amount of oxygen between the outer walls of the cooling vessel and the inside walls of the wagon is minimal. This also contributes to fire safety. With the trolley doors • «*** closed, the aluminum / steel walls of the trolleys protect the radiator from impact.

35 2 119506 EPP cellular polypropylene is used as the cooler material. The radiator is made of two matching pieces and they are connected to each other by a tongue and groove connection. The container door / door opens with hinges up or down, depending on the application. Both cover and body parts are easily removable for cleaning 5. The dishwasher safe.

The cooling capability of an airplane-based radiator is based on a leakproof container and insulating material. Only when the door is opened is air allowed to enter the radiator, as opposed to 10 on non-tight trolleys. The protruding knobs on the edge of the door / deck secure it securely to the trolley body and door during transport.

The cooler is cooled with specially made -3 degree cold gel bags. With gel bags, the cooling and distribution of cold air inside the cooler 15 are uniform, controlled and long-lived.

Temperature control and reporting.

The temperature inside the radiator is controlled by a temperature monitoring system that can be mounted on the radiator door / door / submersible.

20 The temperature sensor mounted on the radiator measures the temperature inside the container: continuously or at desired intervals. The measuring device attached to the radiator has the ability to verify the current indoor temperature. It is also possible to: ·: ··: attach the USB connector so that the temperature results can be transferred to a computer for reporting and self-monitoring.

: · .. 25 The inside of the radiator is grooved and this allows for the use of metal perforated plates as space dividers. The perforated plates facilitate the movement and distribution of cold air: V evenly inside the radiator.

In particular, the airplane according to the invention is suitable for use in airplanes. the cooler is characterized by what is set forth in claim 1 · · · *. characterizing part.

The invention will now be described in more detail with reference to the accompanying drawings, which illustrate the structure of the invention.

3, 119506

The air-cooled cooling vessel consists of two identical halves 1 and 2 attached to each other, which are manufactured by industrial extrusion of EPP cellular polypropylene.

5 The halves are connected to each other by a tongue and groove connection 3, which allows easy attachment and opening of the parts for cleaning and maintenance.

The hatch 4, which serves as a cover for the radiator, is secured to the housing by plastic hinges and is easily removable from the housing for cleaning. A small recess is grooved in the top of the door to facilitate opening of the door.

10 The bottom of the radiator has a hinge and the hatch has a latch 6.

Inside the radiator, the inner walls are provided with grooves 7a, 7b, 7c for teared aluminum shelves.

A torn aluminum shelf 8 is placed in the upper groove 7a and the next 7b of the radiator.

15 Depending on the cooling need, 1 or 2 cooling gel bags 9 are placed on top of each other.

The shelf grooves are dimensioned so that when the cold gel bag expands by + 10% during freezing, the gel bag fits snugly between the shelf and the top of the body.

In this case, the cold air is released only downwards through the perforated plate shelves 20 and thus the cooling time is extended. If longer cooling time is required: and / or higher cooling capacity, place two gel bags over each other and • ·: perforated plate shelf in position 7b.

• · · *: **: Shelf space 7c is reserved for the perforated plate shelf, allowing products to be distributed evenly inside the radiator without slipping.

25 Specially designed gel bags of> 3 degrees Celsius are used for cooling, which have an effective and long-lasting cooling capacity. The gel bag consists of a food-approved wrapper with three small gel bags inside.

The temperature is controlled and measured by a measuring device 10 mounted on the radiator door. The measuring device is positioned in the center of the door so that the • • door *. * ··. the front has a small hole 5-7 mm in diameter for the 11 measuring devices and • · · ·. the inside is at the same location with a recess 12 with a temperature sensor knob 13 of the measuring device • · i. The temperature sensor measures the inside temperature * “of the radiator at desired intervals or continuously. The measuring device 14, which is mounted during the measurement of the hatch front cover, shows the temperature inside the radiator 4 119506 by flashing green or red light. The parameters of the measuring device can be set at desired intervals and / or times. For example, it can be defined that the interior must remain below + 8 degrees throughout the flight and / or return flight, so that the food inside the cooler is still hygienic and marketable. 5 The sensor is permanently installed in the door, and the door can be easily removed from its hinges during washing or maintenance of the radiator.

The measuring hole 10 can also be fitted with a USB cable game 15, which provides the computer with statistics on the temperature inside the radiator and on temperature fluctuations. Both the red-green light measurement and the USB cable 10 measurement can be done without opening the door so the temperature inside the radiator will not change. The radiator dimensions are designed for airplane service trolleys so that they fit snugly into the trolley depending on the application. There is no extra space between the inside of the trolley and the outside of the radiator, so the radiator can withstand even heavy movement and possible 15 turbulence.

Alternatively, the cooler can also be placed tightly inside the KSSU cabinet in the airplane 's kitchen.
