Description

"FROZEN PRODUCTS EXPENDING MACHINE"

TECHNICAL FIELD OF THE INVENTION

The present invention has its field of application mainly in the mechanical and electrical area since it provides a vending machine for frozen products.

BACKGROUND

Document KR10-2005-0017128, 03/02/2005; It describes a refrigerator with freezing characteristics and dispenser which is used in conventional domestic use, dispatches ice through a closed system and does not solve a commercial need, to collect and dispatch simultaneously. The invention that is intended to be patented is distinguished by the use of a coin container to dispatch the products it contains; It is rechargeable and its application is commercial.

It should be noted that vending machines display products in cabinets which are dispatched by various mechanical means such as screws that, while rotating, push the product selected by the user to a ramp or slide to be deposited in the shipping container where it can be removed with relative ease. The problem with this type of machines is that the dispatch mechanisms usually get stuck and do not stock the product, they are machines that need too much space for operation, their visual impact is zero, they only keep but do not freeze the products; They are very dangerous because they use a large glass that is placed in front so that users can see and select the product of their choice.

6a, mentioned above, the other end is fixed at the bottom of the lower housing 3a, just in the position of the hole 9a, which corresponds to a product dispatcher door 8, which is insulated inside and is fixed in the upper cover 9, by means of a hinge 8a, it carries in the central part a handle 8b, which serves to open it and take the product 29, and once taken, it closes by itself, thanks to a spring, which is fixed between its back and the post 6a, adjacent to ramp 6a, and; a coin container box 22, made of rectangular-shaped plastic, which is placed on the shelf 22b, being just below the lower freezer 3, and which serves to receive and store the coins that fall from the coin receiving device 20, once which is turned Ia knob 20c, and slide through a channel

22a, which is placed between the lower housing 3a, and the upper front cover 9.

The work efficiency of this frozen products vending machine 1, is that, as described, the freezer 3, and the freezer 4, have two successive sections of different diameters and spaced apart, are made of a material such as stainless steel, copper, aluminum and insulation (polyurethane), the components will function according to the capacity of the motorized unit and its temperature selection.

Operation of the Frozen Products Vending Machine

The frozen products vending machine works as follows: once installed, it is connected to the 127 VAC power grid and the freezing temperature is selected by thermostat 18, then the desired amount of product 29 is placed, inside The hopper 4c, opening the upper lid 5a, and verifying that when closing it, it is perfectly sealed to avoid energy losses; after approximately three hours, the product 29 will be frozen and ready for dispatch, when a coin with the required denomination is introduced, according to the type of coin receiving device 20; when said coin is introduced, the knob 20c can be rotated, which in turn will rotate the dosing disk 19b, placing only one product 29, on the ramp 6, which will roll until it reaches the dispensing lid 8, Ia which when opened by means of the handle 8b, will allow the product 29 to be taken out, ready to be tasted. Based on everything described above, it can be affirmed that the Frozen Products Vending Machine provides the following advantages: it is conformed with a reduced number of components, compared to the machines existing in the state of the art, it is easy to transport and handling, its maintenance in very simple, is composed of two freezers connected to each other and that help to reach and maintain better the desired temperature, since it reaches temperatures of up to -30 degrees Celsius, it occupies little space for its installation and operation, Its design is original and attractive and has a high visual impact.
