UNITED I STATES JEAN GEORGES MEYNIEU, OF BORDEAUX, FRANCE.
yCONS'I'RUC'IION OF REFRIGERATEUR CHAMBERS.
Application led July 23, 1924, Serial No. .727,815, and. in France July 27, 1923.
The present invention. relates to improvements in the construction of refrigerator chambers intended for the transport of perishable provisions or goods, especially fish, meat, fruit, etc. These refrigerator chambers are characterized by special .arrangements provided for effecting the eirculation of the air and ensuring the coolingV of same.
The ice intended to produce the cold is placed in a compartment situated in the upper portion and separated by a tight-fitting partition from the cold chamber properly so called. The air cooled by the ice descends through suitable passages into the chamber containing the provisions. It circulates round these provisions, becoming slightly warmed by the contact and taking up impurities, and ascends, through other passages, to the ice compartment to be'there re-cooled and rid itself of a portion of the impurities collected during the cycle, the circulation then continuing in the same manner as before.
The water resulting from the melting of the ice does not drop down onto the provisions in transit, and consequently does not return thereto the impurities collected by the air during each passage.
In the accompanying drawing, Figure 1 is a longitudinal section of a refrigerator chamber according to the invention, and Figure 2 is a cross section.
Between the outer partitions 1 and 2 is provided a space 3 serving for the circulation of the air and forming an insulating jacket. In the interior of the chest formed by the partitions 1 and 2 is placed a chest 4, which is separated from the partitions 2 by some insulating material 5, for example, cork dust. In the upper part of the chest 4 are arranged ice tanks 6, mounted on suitable supports, the bottom of which is in the form of a grating 7 and the inclined sides are provided with perforations 8 to drain away the water resulting from the melting of the ice. Above the ice tanks 6, openings closed by covers 9, 10 are provided in the partitions for introducing the ice.
-The water resulting from the melting of the ice contained in the tanks 6 runs down a slightly inclined shoot 11, formed by the upper face of a partition 12, which is supported by another partition 13 from which it is separated by a space 14 into which the warmed air escapes through vertical vents 15. These two partitions constitute the roof of the actual refrigerator chamber 16. The
yshootvll is suitably sloped towards oney of the vertical partitions forming the chest 4,
so as to enable the water coming from the ice tanks 6 to drain into coils 17 which are set up in a vertical plane and drain the water out of the refrigerator. vided at the lower end of the coils prevent air from outside 'entering the interior of the refrigerator. The coils 17 maybe open on their upper surface, as shown in Figure 1.
Vertical sleeves 19 arranged in a suitable manner against the vertical walls of the cold chamber enable the cold air to circulate round the provisions contained in the cold chamber 16.
The air which has become warmed in circulating over the provisions is drawn off through the vents 15 which lead it into the space 14 provided between the two partitions 12 and 13 forming the roof of the cold chamber. The vitiated air is then led through vertical sheaths or sleeves 20, over the top of the ice tanks 6, where it is recooled and purified before being returned to the cold chamber.
This arrangement ensures the perfect and continuous circulation of the refrigerated air through the provisions, in enabling the air to escape from the cold chamber.
Easy access is obtained to the cold chamber 16 through doors 21 provided in the longer sides.
Hooks 22 attached to the top of the refrigerator enable this to be easily lifted by a lifting device and deposited on a platform of any kind such as a wagon, cart ships hold, etc. p
The sheaths or sleeves 20 for drawing off the warm air, and the cold air inlet 19, which are of rectangular section in the example illustrated, may be of variable shapeand dimensions and, moreover, may be arranged on the outside of the cold chamber, if some kind of openings or passages are provided.
The refrigerator illustrated maybe made of suitable dimensions to accommodate cases of perishable provisions, or it may be fitted with trays suitably disposed in the interior of the cold chamber and on which the provisions are laid, or fitted with hooks for hanging and securing pieces of all kinds (meat, fish, ete).
Improvements in the construction of refrigerator chambers intended for the trans- Siphons 18 pro- Y lUU cnn
port of perishable provisions or commodities7 1n which, by means of suitable devices. a
continuous circulation of the enclosed air is maintained, said air, when cold, beingy warmed by contact with the provisions and, when warm, being re-eooled by contact with the ice arranged in the top of the cold chamber, thus describing the thermo-Siphon cycle said improvements being characterized by:
Claim:
A refrigerator including,` a body composed of side7 top, and bottom walls, a partition arranged in the interior of the body dividing the latter into upper and lower chambers, said partition being hollow to provide an internal space for the passage of air and having openings in the lower portion thereof
