Abstract
Description
- The present invention refers to a cooling-freezing apparatus comprising at least one thermally insulated compartment for receiving goods encapsulated with a case that can be closed by a door or a cover, said case comprises circumferential walls and a back wall, and a device which facilitates opening the door of the cooling-freezing apparatus.
- In order to create a temperature difference between a thermally insulated compartment for receiving goods and the surrounding atmosphere a cooling system is provided, such as a compressor cooling system or an absorption cooling system or similar. The temperature of the goods and the air in said thermally insulated compartment changes due to the periodic operation of the cooling system and/or occasional opening of the door and the compartment, respectively, causing a pressure oscillation in the thermally insulated space and, as a result, air exchange with the surrounding atmosphere. Each opening the door and the cover, respectively, results in a part of the air in the thermally insulated compartment to be replaced by warmer air from the surrounding. After the door and the cover, respectively, has been closed a negative pressure is built due to the cooling of said warmer air, said negative pressure sucks warm and moist air from the surrounding into the inside of the cooling-freezing apparatus and, respectively, said compartment. The excessive moisture from the air is deposited on cool surfaces in the form of dew or white frost where it accumulates and creates ice. The pressure equalisation between the surrounding and the thermally insulated compartment may take more time, depending on the tightness of the case and the sealing surfaces between the door and, respectively, the cover and the compartment. Said negative pressure makes difficult or even prevents temporarily to open the door and, respectively, the cover of the compartment. In order to facilitate opening the door and, respectively, the cover various mechanical systems and connecting cavities with the surrounding atmosphere are utilised, so that the pressure inside the cooling-freezing apparatus and, respectively, the compartment equalises faster with the surrounding pressure. A drawback of such solutions is accumulation of white frost, particularly around the connecting cavity, on inner surfaces of the apparatus and on the goods arranged in the vicinity of said opening.
In order to remedy said problems several solutions have been disclosed that provide for utilisation of a special demoisturizing unit as a part of the cooling system, or a renewable drying agent in the sense of a molecular sieve arranged inside the cooling-freezing apparatus or in said connecting cavity. When the drying agent is placed inside the apparatus, the available space is substantially reduced, and also the white frost created around the connecting cavity is eliminated in a smaller extent. In addition, the user of the cooling-freezing apparatus must remove said drying agent after the latter is saturated and regenerate it or install a new one, if the creation of the white frost is to be prevented in the cooling-freezing apparatus.
Embodiments comprising a drying agent in the connecting cavity do reduce entering the moisture into the apparatus and, respectively, the compartment substantially, however, replacing or regenerating of such drying agent is rather difficult. Arrangement in the connecting cavity reduces locally a thermal insulation of the apparatus, or reduces a useful volume thereof. - It is the object of the present invention to create a pressure equalising device with a cooling-freezing apparatus, which remedies drawbacks of the know solutions.
- The object as set above is solved, according to the present invention, by features according to the characterising clause of the
claim 1. The invention is disclosed in detail in corresponding subclaims. - The invention is further described in detail by way of non-limiting embodiment, and with a reference to the accompanying drawings, where
Fig. 1 a simplified view of a cooling-freezing apparatus, Fig. 2 a longitudinal section of a pressure equalising device according to the invention, Fig. 3 a three-dimensional view of a connecting channel, and Fig. 4 a three-dimensional view of the pressure equalising device. - A cooling-freezing
apparatus 1 comprises at least one thermally insulatedcompartment 2 for receiving goods, saidcompartment 2 being encompassed with acase 3 and can be closed by adoor 4 or a cover. Saiddoor 4 can be formed as an upright door or as a horizontal door, depending on the embodiment of the cooling-freezing apparatus1. The invention is further described as the embodiment of anupright apparatus 1. - Said
case 3 comprise side walls, a bottom wall and a top wall, and aback wall 5. Acondenser 6 know per se is arranged along theback wall 5, at the outer side and in the bottom area thereof. In order to prevent creation of a negative pressure in thecompartment 2, aremovable device 7 for equalising pressure in thecompartment 2 and, respectively, in the cooling-freezingapparatus 1 is arranged at the outer side of one of the wall of thecase 3 or thedoor 4, and, in the present embodiment, at the outer side of theback wall 5. Saiddevice 7 is preferably arranged in the area directly above thecondenser 6 of the cooling-freezingapparatus 1. Saidpressure equalising device 7 is connected with the interior of the cooling-freezingapparatus 1 and, respectively, with the interior of the compartment w by means of a connectingchannel 8 formed in saidback wall 5. The connectingchannel 8 extends inclined downwardly in the direction from the interior of thecompartment 2 toward the surrounding. Adrying agent 9 is arranged inside thepressure equalising device 7, in a form of a molecular sieve for instance. - Said
pressure equalising device 7 is formed as acontainer 10 comprising atubular protrusion 11 that is tightly insertable into said connectingchannel 8. Saidtubular protrusion 11 extends from thecontainer 10 with approximately the same inclination as is the inclination of the connectingchannel 8. The latter is formed at the outside of theback wall 5 with aflange 12 configured for the attachment of thepressure equalising device 7. Saiddevice 7 forms with saidflange 12 either a positive joint, such as a snap-in, and/or a non-positive joint, such as at least one threaded means. To this end thecontainer 10 is provided in the area of the connection with the tubular protrusion with aflange 13 comprising either the opposite blocking means as saidflange 12 of the connectingchannel 8, and/or at least one throughhole 13a for accommodation of said threaded means. Furthermore, at least one wall an/or abottom 14 of thecontainer 10 is formed with at least one throughhole 15, preferably with a plurality of throughholes 15 for the air to flow from the surrounding into the interior of thecompartment 2. The total area of the through holes amounts to the value which enables satisfactory air flow and, thus, fast pressure equalisation between the interior of the cooling-freezingapparatus 1 and, respectively, thecompartment 2 and the surrounding atmosphere. - Said
container 10 can be made as a single disposable part that can be removed and disposed after thedrying agent 9 has been consumed. An alternative embodiment provides thecontainer 10 formed with alid 16 which closes thecontainer 10 at the side opposite to thebottom 14. In this case, the consumeddrying agent 9 can be removed and replaced with a new one. Said dryingagent 9 can be in the form of a granulate or a monolithic blank that can be accepted by thecontainer 10. In any case, each said throughhole 15 is smaller than the size of a granulate and, respectively, of a single grain of thedrying agent 9, thus, preventing the particles of thedrying agent 9 to fall through theholes 15. Saidcontainer 10 can be made of a high temperature resistant material, thus, enabling regeneration of thedrying agent 9 without opening thereof, in an oven for example. In addition, thecontainer 10 can be made of a translucent material, which enables fast insight whether thedrying agent 9 is already consumed and the regeneration thereof is required. To additionally improve detecting the consumption of the drying agent a pigment can be added to thedrying agent 9 which changes the colour depending on the moisture rate and saturation with moisture, respectively. - When assembled, said connecting
channel 8 and saidtubular protrusion 11 form a positive joint, thus, preventing the air from the surrounding to enter the cooling-freezingapparatus 1 and, respectively, thecompartment 2 anywhere else but through the throughholes 15 and thedrying agent 9. Said interference fit is additionally supported by said positive joint between theflange 12 of the connectingchannel 8 and theflange 13 of thecontainer 10. To this end theflange 12 is formed in the area of the entrance of thetubular protrusion 11 with at least onetooth 17 which mates an appropriatelyundercut edge 18 of theflange 13. - Due to the pressure differences which occur as a result of temperature changes with periodical operation of the cooling system or opening of the door/cover, the air flows from the surrounding into the interior of the apparatus and vice versa. The air flows through the
drying agent 9 in thecontainer 10 which is arranged at the outside of theapparatus 1, preferably above thecondenser 6. When entering theapparatus 1 thedrying agent 9 retains water molecules and dry air continues its way to the inside of the apparatus. In opposite case, when dry air flows from the freezer, said dry air absorbs on its way out water molecules from thedrying agent 9 and release them into surrounding. Since thecontainer 10 with thedrying agent 9 is arranged directly above thecondenser 6 and, respectively, in the close vicinity thereof, natural heat convection additionally contributes the regeneration of the drying capacity of the absorbent. If extremely high moisture is present in the surrounding atmosphere, the capacity of thedrying agent 9 might be too low for a long term efficiency. In such cases thedrying agent 9 can be regenerated by drying at the required temperature or by being replaced with a new one. - One of additional advantages of the external arrangement of the
pressure equalisation device 7 according to the invention is also shown in a fact that it does not decrease the useful volume in the freezer. Additionally, saiddevice 7 can be incorporated into every old cooling-freezing apparatus where such a device was not provided initially. Therewith, the accumulation rate and the quantity of the white frost on the evaporation surfaces is lowered, and opening the door/cover is substantially easier. When reconstructing existing apparatuses, a hole is made through the insulation at the appropriate spot, a connectingchannel 8 being placed in said hole. Aflange 13 of thecontainer 10 is snapped-in by means of theedge 18 to theflange 12 of the connectingchannel 8, and if necessary additionally fixed by screws. - It is also possible according to the present invention that the
device 7 for equalising pressure in the cooling-freezingapparatus 1 is arranged on or in any other wall of thecase 3 or in thedoor 4, and not only on theback wall 5. In addition, saiddevice 7 can be arranged outside or inside the cooling-freezingapparatus 1. It is provided for, according to one of the possible embodiments, that thedevice 7 is formed in a handle of the cooling-freezingapparatus 1, which substantially facilitates the user to access thepressure equalisation device 7 and to manipulate therewith.
