Description
- The present Utility Model application has as an object the registration of an improved insulating device for ice creams and frozen food dispensing machines incorporating remarkable innovations and advantages in front of the present thermally-insulated systems at the cooled dispensing machines.
- More particularly the present invention consists in the arrangement of an insulating curtain with vertical strips in front of a cooled-products storage chamber of a dispensing machine being thus avoided any interchange of the environmental air with the inside cold air during opening, loading and other operations, and also prevented an ice or frost formation which could cause a blocking of the inside motions and product adherence between them and the machine structural members.
- Presently several types of machines for automatical dispensing of drinks and food products are available in the market. Within this type of machines is common to find the ones arranging products by columns to dispense them by gravity. Usually, the temperature set for the product maintenance chamber is higher than that of the water freezing temperature, the environmental humidity condensation can thereby only be caused at most in the walls and in the stored products. The issue arises when the cooled chamber of the dispensing machine should be quite truly under the freezing point when ice and frost are formed on the products; machine surfaces and inside motions causing machine blocking and malfunction.
- The improved insulating device for ice creams and frozen food dispensing machines object of the present registration is characterized in that it comprises insulating means for the cooled product storage chamber, but allows machine to be loaded by the operator when replenishing it with product. Effectively, when the machine is operating and closed, the inside low temperature causes condensation of the environmental humidity which is then stored frostlike.
- During the machine regular replenishing operations, a noticeable thermal skip is caused between the inside and the outside of the storage area. The machine inside is really at a temperature which can easily go down to about -30°C, while the outside temperature can vary between 20°C and 40°C. On said process, any air present inside the machine is renewed by taking a higher humidity-filled outside air. When the machine is closed and the renewed air temperature is falling, said humidity similarly goes down by condensing itself as ice and frost, an upshot fully undesirable.
- With the present invention, during the machine's product reloading, any interchange of the inside air with the outside air is avoided on the one hand and if air leakage from outside is perceived, this air may then go on by raising a progressively-growing ice layer in the sensible portions of the cooled inside, on the other hand.
- The present invention comprising the arrangement of a curtain of insulating members at the frontal side of the storage area of the dispensing machine just behind the inside doors. Said curtain is made up with a plurality of vertically-arranged flexible strips, from wider to narrower ones, fitted at its top portion and embracing all the height of said storage area up to the isothermal insulating frame lower side. Said isothermal frame dividing the cooled machine inside into two sections, the top section pertaining to the product storage area and being thereby the one mostly used during the products replenishment operations into the machine and the bottom section pertaining to all the product delivery and dispensing motions, covered by a purposely-prepared second door. Both doors are fully independent to avoid any unnecessary door opening. The access distribution in two independent doors really means that two corresponding curtains are available, the top curtain made up with vertical strips of insulating material and the lower curtain indistinctly with strips or a single sheet embracing all the bay defined by the isothermal lower frame. Said doors having at its inside perimeter a preferably neoprene-insulating gasket, the doors fitted to the isothermal frame to avoid any possible air leaks to the inside. The machine outside door is closed on these two doors.
- The curtain vertical strips insulating the cooled inside chamber from the outside space, but allow the operator to easily insert products through the existing slits between two contiguous strips. The contiguous strips are slightly overlapped to assure inside absolute hermetical sealing, and in case air leaked through the doors, humidity is then condensed on the curtains and does not get to go into the cooled chamber.
- To complete the following description and to help a better understanding of its characteristics, the present description is accompanied by a set of drawings which figures illustratively and non-exhaustively show the most substantial details of the present invention.
- The single figure shows a perspective view of the device fitted to a dispensing machine with doors opened.
- In view of the discussed figures and in agreement with the adopted numbering, it can be noted therein, a preferred although non-exhaustive embodiment of the invention, which consists of a dispensing machine (2) having a front door (6), two thermally-insulating inside doors (5) and a cooled storage chamber (1), each of said inside doors (5) having an insulating gasket (4) at its lower perimeter and two curtains (8, 9) are placed on the isothermal frame (7) in association with each of the doors (5), said curtain (8) being made up with a plurality of vertically-arranged, slightly mutually-overlapped strips of insulating and resilient material. The top curtain embracing from the cooled chamber (1) to the isothermal frame (7) central traverse beam present around said chamber (1). The lower curtain (9) is arranged from the frame (7) central traverse beam to the frame lower edge, and is made up with a single sheet of insulating and resilient material separating the stored product dispensing electromagnetic members (3) from the outside.
