Technical field
The present invention relates to a kind of chiller, specifically, relate to a kind of frostless chiller that comprises the defrost water passage being sealed by channel enclosed device.
Background technology
In the chiller of the above-mentioned type, by circulated air system, make air be recycled to refrigerator compartment from being positioned at the evaporimeter of actual refrigerator compartment outside.Ice is formed on evaporimeter, and termly to evaporator defrost, wherein defrost water is discharged in evaporation tray through for example defrost water passage.In order to prevent that surrounding air from flowing into refrigerator compartment or flowing into vaporization chamber in frost-free means in the situation that through defrost water passage, conventionally, siphon pipe is integrated in defrost water passage.This is full of defrost water, prevents thus any further air exchange.
The shortcoming of siphon pipe solution is: until siphon pipe while being full of water-that is to say, for example, until the end-surrounding air of the first defrosting cycle and moisture can be flow into refrigerator compartment or be flow to evaporimeter by defrost water passage, and cause polluting and energy loss.
Applicant has proposed integrated water-soluble channel enclosed device in defrost water passage in application more early, this prevented surrounding air flow through defrost water passage until described locking device by defrost water, decomposed completely.Then, water siphon pipe is also full of defrost water and carries out its function.
Yet this complete water-soluble channel enclosed device can be manufactured complexity and not be highly stable in mechanical aspects.As a result, in some cases, sealing is also not exclusively reliable, because it is unable to bear mechanical stress.In addition, a large amount of water-soluble materials is washed in evaporation tray and stays there.
Summary of the invention
Therefore object of the present invention is to provide a kind of to be had at running (commissioning) chiller of the replacement solution of the sealing of defrost water passage before.
This object utilizes a kind of chiller as claimed in claim 1 to realize, wherein defrost water passage by water-insoluble or only the water miscible channel enclosed device of part seal.Yet channel enclosed device is remained in defrost water passage or is remained on defrost water passage by water-soluble material.Channel enclosed device need to not made by water-soluble material, only needs to guarantee to eliminate when contacting with water open this passage of fixing and channel enclosed device of the channel enclosed device in defrost water passage.
Actual channel enclosed device can comprise any material, such as plastics, expanded polystyrene (EPS), rubber, glass or metal or their composite.Preferably, this needs at least substantially material stable aspect size, such as for example plastics.This makes sealing more reliable, because present water-soluble medium self is no longer exposed to mechanical stress and the atmospheric fluctuation of production or In transit.On the contrary, main stress is absorbed by water-insoluble channel enclosed device.
In addition, reduced the use of water-soluble substances.This can reduce cost, but primary be to have reduced the pollution of water-soluble substances to defrost water.This can reduce secondary effect, such as the biological growth in evaporation tray or in actual defrost water passage.This has increased the operating reliability of device and has improved its quality.
Chiller in implication of the present invention can be especially by automatic defrosting, and is fridge-freezer or the horizontal refrigeration cabinet of for example refrigerator, vertical refrigeration cabinet, combination.It is family expenses chiller preferably.Frostless chiller in implication of the present invention is such chiller: evaporimeter is arranged in vaporization chamber in the outside of refrigerating chamber, and cooling-air passes through cooling air channels by the fan circulation between vaporization chamber and refrigerator compartment.Evaporimeter in this chiller can be defrosted by Defrost heater.
The defrost water that the defrost water passage of chiller produces (especially, on evaporimeter) in chiller is transported to the outside of chiller, thereby defrost water can be used the used heat from compressor to evaporate in chiller outside especially.Defrost water passage is for example pipe, flexible pipe or groove, and preferably leads to evaporation tray, and this evaporation tray is positioned at compressor top valuably.
In order to prevent that surrounding air from being flow into refrigerator compartment or being flow into vaporization chamber the frost-free means in the situation that by defrost water passage, siphon pipe is preferably integrated in defrost water passage, described siphon pipe is full of defrost water, and prevents that subsequently surrounding air from entering into refrigerator compartment or the in the situation that of frost-free means, entering into vaporization chamber.
Channel enclosed device can be fixed in defrost water passage or be fixed on defrost water passage by the water-soluble organic or inorganic material as adhesive especially.These can be for example cellulose or gel or salt (such as, salt).Adhesive preferably spreads upon the whole circumference of defrost water passage and keeps by this way channel enclosed device, and channel enclosed device has the external diameter of the internal diameter that is slightly less than defrost water passage.
Can also use the mechanical fastening system made by water-soluble material (such as, for example clip or locating ring) as fixture.Here can use alternatively salt or cellulose.
According to preferred embodiment, channel enclosed device is made of plastics.This for example allows as the cheap production of injection moulding part and allows the reliable sealing of defrost water passage, because produced the stable passage closure member that can stand production period and In transit mechanical stress and atmospheric fluctuation.
Utilize the design of the geometry of this channel enclosed device, it should be noted, when fixture is decomposed, although fixture is stayed in defrost water passage, in fact this also opened defrost water passage.Therefore the external diameter of channel enclosed device is preferably much smaller than the internal diameter of defrost water passage, thereby when separation, it can not be stuck in the lateral attitude of defrost water passage to such an extent as to make it continue the described passage of sealing, but on the contrary, on the longitudinal direction of defrost water passage, arranges.On the other hand, also can designed channel locking device, so that it is flushed out defrost water passage by defrost water.
According to preferred embodiment, channel enclosed device is embodied as plate or the dish being made of plastics especially.This is for example inserted in the flexible pipe or barrel portion of defrost water passage.Preferably, the geometry of described dish is adapted to the cross section of defrost water passage by this way, and defrost water passage can seal thus, and utilizes any water-soluble material to fix described dish.What be suitable for this is for example water-soluble binder or water-soluble clip.This dish is for example laterally arranged in defrost water passage with respect to the flow direction of defrost water, and almost remains on completely in the section of defrost water passage, because its circumference bonds to the inwall of passage in the mode of sealing.When adhesive dissolves, dish tilts to the position that is parallel to longitudinal direction, in this position, and the cross section of open defrost water passage.
The thickness of dish is > 0.1mm (it is not thin-film material) preferably, is more preferably about 0.5-1.5mm.
Channel enclosed device can be inserted in defrost water passage at diverse location and with distinct methods, is described below thus some preferred embodiments:
According to the first preferred embodiment, channel enclosed device is embodied as the vinyl disc of the port of export top that is placed on defrost water passage, is embodied as lid.This vinyl disc can be fixed on there by being bonded in the port of export of pipe, or keeps by water-soluble locating ring.
According to the second preferred embodiment, channel enclosed device is embodied as vinyl disc in channel part part, and channel part part forms the separate part of defrost water passage.Therefore, defrost water passage is not single part, but has independent channel part part (for example, tubular member), this channel part part is for example placed on defrost water passage in the outlet of defrost water passage, or is inserted between the defrost water outlet and defrost water passage of chiller.Vinyl disc has been integrated in this channel part part, and wherein here, dish can bond to the inwall of channel part part.This solution has advantages of such: can be with conventional method production defrost water passage.
According to the 3rd embodiment, channel enclosed device is embodied as smooth or spherical stopper in defrost water passage, described stopper contact during water with the sidewall decomposition of defrost water passage and be rinsed away from defrost water passage.
Preferably, described stopper has at least one through hole, and wherein said at least one through hole can utilize ventilative film sealed.Here, channel enclosed device can for example be embodied as the porous ring being inserted in defrost water passage.
The sealing of channel enclosed device needn't represent 100% ventilative property in each situation, but only there is insignificant air exchange in sufficient to guarantee for example when the normal transport of chiller and operation between the inside of chiller and environment, this can not cause evaporimeter any more serious freezing significantly.Especially, when the door of chiller is opened, channel enclosed device prevents that more substantial air (for example, > 10ml or > 100ml) is inhaled into inside, causes short time vacuum thus in inside valuably.
Preferably, channel enclosed device is at least breathable on the flow direction of defrost water.The air that this character moves away for the defrost water that allows to flow into from defrost water passage leaves.This guarantees between defrost water and channel enclosed device, not form bubble in being embodied as the defrost water passage of pipe or flexible pipe, and this can prevent channel enclosed device or its fixture contact defrost water.Therefore, this has guaranteed that defrost water passage is open reliably in preset time.
This point can realize, because at least one via arrangement with little internal diameter is in channel enclosed device, described opening is connected to each other the region of upstream and downstream that is positioned at the channel enclosed device of defrost water passage.The internal diameter of through hole, for for example 0.01mm to 1mm, is preferably 0.05mm to 0.5mm.Especially easily in the channel enclosed device being made of plastics, (especially, in vinyl disc or plastic stopper) introduces this through hole.Therefore, the present invention allows the description to the ventilative cross section of explication in channel enclosed device, utilizes complete water miscible channel enclosed device just can realize this point very difficult in the situation that.
Preferably, channel enclosed device is only breathable on the flow direction of defrost water.For this reason, it comprises or forms for example check valve, comprises especially or forms mushroom valve or globe valve.This can be arranged in the vinyl disc that for example forms channel enclosed device.
On the other hand, ventilative channel enclosed device also can comprise at least breathable diaphragm on the flow direction of defrost water.Channel enclosed device can comprise the through hole being sealed by this diaphragm.Diaphragm can be water miscible.Diaphragm is for example realized by this way, and, when pressure increases, it allows more air pass through, and wherein preferably guarantees in the inside of only opening while there is pressure differential air on a small quantity due to door and be inhaled into chiller.Yet diaphragm is preferably realized, so that the pressure of the water gathering is enough to allow the air in defrost water passage to flow towards outside through diaphragm., and compare in other direction, diaphragm is more ventilative on the flow direction of defrost water valuably for this reason, and particularly preferably, it is one-way breathable diaphragm.
If staying in defrost water, the decomposing material of the fixture of channel enclosed device can in the evaporation tray of collecting defrost water, cause the residue of biological growth, as countermeasure, biological growth inhibiting substances can be placed in the evaporation region of defrost water, such as for example salt or other suitable chemicals (such as, cationic surfactant).The material that suppresses biological growth can be also biocide, in particular bactericide or fungicide.For example, during this material can be fixed on parcel in defrost water pallet or be fixed in defrost water pallet as tablet, thereby when contact defrost water, discharge this material.
On the other hand, prevent that biological material of growing can be integrated in the water-soluble fixture of channel enclosed device in defrost water.As a result, only, when the fixture of the decomposition due to channel enclosed device causes in fact must preventing biological growth, this material just works.In addition, can in defrost water passage, with respect to channel enclosed device, provide individually this material, for example on the flow direction of defrost water channel enclosed device above and/or below or this material is provided in siphon pipe.
Preferably, channel enclosed device is laterally arranged in defrost water passage with respect to the flow direction of defrost water substantially.Thus, the external shape of channel enclosed device is substantially consistent with the internal geometry of defrost water passage, thereby channel enclosed device seals defrost water passage reliably, until it is because contact water decomposes.Therefore the required size of channel enclosed device is determined by the size of defrost water passage substantially, thereby channel enclosed device can be little and cheap.Defrost water passage can have any cross section, but preferred cross section is circle, square or oval cross section.
Preferably, defrost water passage comprises siphon pipe.Siphon pipe is full of defrost water and therefore prevents that air from entering the inside of chiller at the first defrosting cycle.Meanwhile, defrost water can flow away without any problems.Preferably, channel enclosed device is arranged in after siphon pipe on the flow direction of defrost water.Therefore,, when the defrosting of the evaporimeter of chiller, first siphon pipe is full of defrost water.Only after this, channel enclosed device contact water decomposition.
Particularly preferably, in siphon pipe, water just seals the water level of defrost water passage, and channel enclosed device is arranged in the height of approximate water surface or just above water surface in its minimum point.This has advantages of such: channel enclosed device decomposes as early as possible, but only when the water level of defrost water decomposes when in siphon pipe, horizontal connection very high to such an extent as between siphonal entrance and exit is full of water completely.This preferably has such result: only, after the first defrosting cycle of frostless chiller, channel enclosed device decomposes.In this way, be integrated in alternatively in channel enclosed device to prevent that the material of biological growth from also entering in the water in siphon pipe, it prevents biological growth in water.On the other hand, for preventing that the material of biological growth is arranged in addition before siphon pipe especially on the flow direction of defrost water, thereby it also acts on the water of preserving in siphon pipe.This material can for example be arranged in defrost water passage with tablet form or with any other form (for example,, as salt, gel or liquid).
Siphon pipe can for example be embodied as the tubulose siphon pipe with U-shaped pipe, and its sweep below always remains full of defrost water, prevents that thus surrounding air from entering into vaporization chamber.The production of this embodiment is simple especially.
On the other hand, siphon pipe also can be embodied as ampuliform, cup-shaped, tabular or mitriform siphon pipe.Preferably, corresponding cup is arranged in evaporation tray, so that be fed directly in evaporation tray from the defrost water of cup.Preferably, lid placement is above siphon pipe, although lid allows water to overflow, lid has slowed down siphon pipe or cup becomes dry.The present invention is described with reference to the accompanying drawings.Accompanying drawing only illustrates and does not limit total inventive concept as example.
