The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
[drying device]
First-selection is carried out following detailed description drying device of the present utility model.
Drying device of the present utility model, it possesses hothouse, cooling unit and control part, and, its drying principles is, under the effect of control part, the enclosed environment that enters relatively-high temperature from the gas of the relative low temperature of cooling unit (namely, hothouse) after, owing to the gas of relative low temperature is understood because expanded by heating cause its relative humidity further to reduce, reduce the humidity of hothouse thus, effectively bring into play drying effect.
As shown in Figure 1, in the hothouse 10 of drying device of the present utility model, have for the peristome 11 of accessing article and lid 12 and the air port 13 that is used for covering described peristome 11.
Manufactured materials as hothouse 10 is not particularly limited, but from being conducive to the viewpoint of gas heating process in the hothouse, preferred hothouse 10 is made by the good material of thermal conductivity, for example engineering plastics or metal etc.And, also be not particularly limited as the proterties of hothouse 10, easily manufactured and be easy to the viewpoint that cooperates with miscellaneous equipment on the industrial production, preferred hothouse 10 is cuboid.
Be provided with for the peristome 11 of accessing article and the lid 12 that is used for covering this export department 11 in a side of hothouse 10 (being end face among the figure), when needs are kept at article in the hothouse 10, can open lid 12, by peristome 11, and article are positioned in the hothouse 10.As the set-up mode of lid on hothouse 10, as shown in the figure, the one end is connected with hothouse, when needs with article storage during to hothouse 10, lid 12 is rotated in order to peristome 11 is opened wide around the junction, thus article are put into hothouse 10, rotate lid 12 then to covering peristome 11, and and then can fasten with the buckle (not shown), thereby make hothouse be in closure state.Be appreciated that, lid 12 also can be arranged to separate with hothouse 10, when needs with article storage during to hothouse 10, earlier lid 12 is removed in order to peristome 11 is opened wide, thus article are put into hothouse 10, then lid 12 is directly covered peristome 11, and and then can fasten with buckle, thereby make hothouse be in closure state.In addition, when from hothouse 10, taking out article if desired, then open lid 12 equally, via peristome 11 article are taken out.
And, be provided with air port 13 in a side of hothouse 10 (being right flank among the figure).As the proterties in air port 13, as long as can guarantee that gas flows into or flow out in the hothouse, be not particularly limited, can be rectangle, circle, ellipse etc., easily manufactured viewpoint on the industrial production is preferably rectangle.
Under the effect of control part, make that refrigerating gas replacement process and the interior gas heating process of hothouse in the hothouse hockets.Particularly, during the gas heating process hockets in refrigerating gas replacement process in control part control hothouse and the hothouse, be by the relative humidity in the hothouse and critical humidity being compared, judging whether to carry out hocketing of refrigerating gas replacement process and the interior gas heating process of hothouse then.
When the relative humidity in control part is judged hothouse is higher than critical humidity, produce the refrigerating gas that temperature is lower than dry indoor gas by cooling unit, this refrigerating gas flows in the hothouse 10 by air port 13 then, and with hothouse in the relative high gas of temperature that exists replace, simultaneously, namely 13 flowed out hothouses 10 from the air port by the gas of being replaced.Thus, realize the ventilation effect on moisture extraction that hothouse is interior.
In the refrigerating gas replacement process, the refrigerating gas that cooling unit produces flows into hothouse, and this moment, the hothouse internal pressure was higher than external pressure, and extraneous gas can't flow in the hothouse; After the refrigerating gas replacement process finishes, cooling unit is no longer carried refrigerating gas in hothouse, therefore air port and cooling unit form inner with the outside relative closure structure of hothouse jointly, thereby the higher gas of the outside relative humidity of hothouse can't enter in the hothouse.
And then, under the control part effect, carry out gas heating process in the hothouse.In described hothouse in the gas heating process, because hothouse is made of Heat Conduction Material, the heat conduction takes place and carries out heat exchange in this refrigerating gas and hothouse external environment, make that the refrigerating gas temperature is natural, steadily rise, so the refrigerating gas expanded by heating, thereby reduce dry indoor air relative humidity.Therefore thus, owing to dry indoor gas need not extra heating for natural rewarming, in that to reduce the fluctuation of relative humidity simultaneous temperature little and need not to increase energy consumption.
At this moment, if dry indoor relative humidity subcritical humidity, then control part controls that hocketing of gas heating process stops in above-mentioned refrigerating gas replacement process and the hothouse.
At this moment, if dry indoor relative humidity still is higher than critical humidity, then the control part alternation procedure of controlling gas heating process in above-mentioned refrigerating gas replacement process and the hothouse continues to repeat, and is reduced to subcritical humidity until dry indoor relative humidity.
In said process, the influx that flows into hothouse within a certain period of time about refrigerating gas be according to stored article in the hothouse quantity, volume, highly, the conditions such as switching number of times of the peristome of the temperature of area, weight and dry indoor gas, relative humidity, hothouse regulate.
Carry out in order to make that above-mentioned refrigerating gas replacement process is more effective, guiding device can also further be set in drying device.About the setting of guiding device, as shown in Figure 2, can be in the air channel of cooling unit and the place, air port that is positioned at drying device guiding device is set; Perhaps as shown in Figure 3, also can be in the air channel of cooling unit and the place, air port that is positioned at drying device guiding device is set, guiding device also is set in hothouse simultaneously.
Particularly, as shown in Figure 2, in the air channel 16 of cooling unit, and 13 places, air port that are positioned at drying device 10 arrange guiding device 15, and this guiding device 15 is divided into top, air port 13a and bottom, air port 13b with this air port 13.When control part judges that the refrigerating gas replacement process of drying device begins, then guiding device 15 is from the I(figure of position shown in the dotted line) action solid line to the II(figure of position) time, this moment from the refrigerating gas of cooling unit air channel 16 in along direction A mobile (shown in arrow among the figure), and be at guiding device 15 under the guide functions of position II, it is easier than flowing along direction B to flow along direction C, thereby, under the effect of guiding device 15, refrigerating gas flows in the hothouse 10 via bottom, the air port 13b in air port 13.Simultaneously, continue to flow into drying device 10 inside at refrigerating gas, because 13 13a place, top, air port forms low-pressure area in the air port, therefore dry indoor gas is gone forward side by side into air channel 16 along direction D outflow hothouse 10 via top, the air port 13a in air port 13, finishes gas displacement process in the hothouse thus.
After gas displacement process in the above-mentioned hothouse finished, cooling unit stopped to produce refrigerating gas, and guiding device 15 gets back to the position I from the position II, and covered the part of bottom, the air port 13b in described air port 13 at least.At this moment, under the effect of control part, carry out gas heating process in the hothouse, refrigerating gas in the hothouse is owing to carry out heat exchange and expanded by heating with surrounding environment, gas after the expansion can flow out hothouse and enter air channel 16 by top, the air port 13a in air port 13, thereby keeps the pressure balance of hothouse 10 and surrounding environment.
As shown in Figure 3, except in the air channel of cooling unit and the air port place that is positioned at drying device arrange the guiding device 15, deflector 17 can also further be set in hothouse.Like this can be so that the refrigerating gas that flows into hothouse 10 from bottom, the air port 13b in air port 13 flows through long path in hothouse 10, namely, from the refrigerating gas of cooling unit in air channel 16 along direction A flow (shown in arrow among the figure), and be at guiding device 15 under the guide functions of position II, it is easier than flowing along direction B to flow along direction C, therefore refrigerating gas flows in the hothouse 10 via bottom, the air port 13b in air port 13 along direction C, and flow in hothouse along direction E, flow out hothouse 10 via top, the air port 13a in air port 13 along direction D then and go forward side by side into air channel 16, guarantee that thus refrigerating gas can replace dry indoor gas more fully.
In addition, in order to improve the efficient of refrigerating gas replacement process, hothouse 10 of the present utility model can arrange a plurality of air ports.About the setting in air port, particularly, as shown in Figure 4, air port 13 and air port 14 are set respectively on the side respect to one another of described hothouse 10, and also are provided with the open-close lid 14a that covers described this air port at 14 places, described air port.As the proterties in air port 14, flow out hothouse as long as can guarantee the gas of being replaced, then be not particularly limited, can be consistent with air port 13, be rectangle, circle, ellipse etc., easily manufactured viewpoint on the industrial production is preferably rectangle.
Because described air port 13 is in respectively on two sides respect to one another of hothouse 10 with air port 14, therefore can form wind path in hothouse 10, is conducive to gas flow in the hothouse.Particularly, in described refrigerating gas replacement process, because refrigerating gas is in the 13 inflow hothouses of air port, there is air pressure difference inside and outside the hothouse, make the open-close lid 14a in described air port 14 open, the gas of being replaced 14 outflows from the air port thus are shown in arrow among the figure.
As shown in Figure 5, after described refrigerating gas replacement process finishes, there is not gas differential pressure because hothouse is inner with the outside, therefore the open-close lid 14a in described air port 14 closes under the effect of deadweight and brings into play adverse current and prevent effect, therefore, the refrigerating gas in the hothouse also can't be from the air port 14 flows out hothouses.And then, under common cooperation of air port 13 and cooling unit, form inner with the outside relative closure structure of hothouse, thereby the higher gas of the outside relative humidity of hothouse can't enter in the hothouse, thereby guarantee effectively to realize gas displacement in the hothouse, and in follow-up gas heating process, keep closed state and make refrigerating gas nature rewarming effectively.
In addition, except on two sides respect to one another of described hothouse 10, arranging the air port respectively as mentioned above, can also be as shown in Figure 6, be respectively arranged with air port 13 and air port 14 in hothouse 10 two sides adjacent one another are, and, in order further to improve gas displacement efficient, also in hothouse 10, be provided with deflector 17, by making refrigerating gas 13 flow into hothouses 10 from the air port, and under the guide functions of deflector 17, the long path of stream in hothouse 10, the 14 outflow hothouses from the air port then.
In addition, can also be as shown in Figure 7, a side at hothouse 10 arranges air port 13, and in another side relative with this side two air ports are set, be air port 14 and air port 18, by making refrigerating gas 13 flow into hothouses 10 from the air port, then respectively from the air port 14 and air port 18 flow out hothouses.
In sum, by hothouse toward each other or adjacent side a plurality of air ports are set to form wind path, can improve gas displacement efficient, the drying effect that increases dry indoor air-changing effect on moisture extraction and obtain thus.
Cooling unit as drying device of the present utility model, specifically as shown in Figure 8, drying device of the present utility model comprises cooling unit 50, and described cooling unit 50 comprises parts such as throttling arrangement (for example capillary) 51, condenser 52, compressor 53, air intake duct 54, evaporimeter 55.In described cooling unit, the effect of described throttling arrangement 51 performance throttlings, step-down, the effect of described condenser 52 performance heat radiations, condensation, the effect of described compressor 53 performance compressions, exhaust, the effect of described evaporimeter 55 performance evaporations, refrigeration.And described condenser 52 and described compressor 53 have constituted the high-pressure side (AA) of described cooling unit, and described air intake duct 54 and evaporimeter 55 have constituted the low-pressure side (BB) of described cooling unit.By above-mentioned formation, cooling unit of the present utility model produces the refrigerating gas that temperature is lower than dry indoor gas thus, and forms the environment of relative closure with hothouse.
In addition, described drying device further can possess air supplying part and test section as described below.In described refrigerating gas replacement process, described control part impels described refrigerating gas to flow in the described hothouse by controlling described air supplying part running.Be appreciated that the refrigerating gas that cooling unit produces both can flow in the hothouse naturally, also can under the promotion of air supplying part running, more effectively flow in the hothouse.
And described test section can be the state-detection portion for detection of described cooling unit running status, weight detecting portion for detection of the weight of described dry indoor storage article, volume test section for detection of the volume of described dry indoor storage article, height detection portion for detection of the height of described dry indoor storage article, area test section for detection of the area of described dry indoor storage article, temperature detecting part for detection of gas temperature in the described hothouse, Humidity Detection portion for detection of described dry indoor gas relative humidity, with for detection of in the switching test section of the switching number of times of the lid of described peristome more than one.This be because, described cooling unit running status; The weight of the article of dry indoor storage, volume, highly, area etc.; The frequency of user's accessing article (switching of the lid by peristome embodies, because accessing article all needs to open and close lid at least one times each time); And factors such as gas temperature, relative humidity all can finally influence the interior relative humidity of hothouse in the hothouse, therefore, by detecting the variation of these factors, and then refrigerating gas influx within a certain period of time in the refrigerating gas replacement process adjusted, thereby can effectively bring into play the drying effect of hothouse.
As shown in Figure 9, under the effect of control part 30, detect the running status of cooling unit 50 by test section 40; The weight of hothouse internal storage article, volume, highly, area; The temperature of internal gas, relative humidity; The perhaps switching number of times of lid etc., control part 30 control air supplying part 21 promote the refrigerating gas that cooling units produce and import in hothouse, thereby gas heating process in hocket refrigerating gas replacement process and the hothouse realizes drying effect.
Particularly, described control part is based on the testing result of above-mentioned test section more than any one, in control refrigerating gas replacement process and hothouse, during the hocketing of gas heating process, refrigerating gas influx within a certain period of time in the refrigerating gas replacement process is regulated.
Below respectively by preferred embodiment being elaborated.
＜state-detection portion 〉
Drying device of the present utility model can further have state-detection portion, it is for detection of the running status of cooling unit, and compared by running status and the regulation running status of control part with detected cooling unit, regulate refrigerating gas influx within a certain period of time in the refrigerating gas replacement process thus.
Particularly, as shown in figure 10, operation (ON) time that described state-detection portion the detects compressor t that exceeds schedule time
x, that is, and t at the appointed time
xInner compressor is ON, and then at the ty time inner compressor that surpasses still for ON, at this moment, the gas displacement process begins (ON) in the hothouse, cooling unit produces the temperature refrigerating gas lower than gas temperature in the hothouse, and regulate the influx that refrigerating gas flows into hothouse within a certain period of time jointly by air supplying part, so as rapider, replace dry indoor gas effectively.
When above-mentioned refrigerating gas replacement process carries out t
yAfter time, detect compressor (OFF) out of service this moment, but the refrigerating gas replacement process still was ON and continued t this moment
zTime is then at thereafter t
dCarry out gas heating (relative humidity decline) in the hothouse in time and keep process with the external temperature balance.Detect compressor operating time again until test section and exceed schedule time, then restart said process.
As shown in figure 11, when the temperature that detects the low-pressure side (comprising evaporimeter or air intake duct) of cooling unit when described state-detection portion is lower than set point of temperature T1, then the gas displacement process begins (ON) in the hothouse, this moment, cooling unit produced the temperature refrigerating gas lower than gas temperature in the hothouse, and regulate the influx that refrigerating gas flows into hothouse within a certain period of time jointly by air supplying part, so as rapider, replace dry indoor gas effectively.
When the low-pressure side temperature that detects cooling unit when described state-detection portion was higher than set point of temperature (T1), then the refrigerating gas replacement process finished (OFF), detects the low-pressure side temperature again until test section and is lower than set point of temperature, then restarts said process.
As shown in figure 12, when the temperature that detects the high-pressure side (comprising compressor or condenser) of cooling unit when described state-detection portion is higher than set point of temperature T2, then the gas displacement process begins (ON) in the hothouse, this moment, cooling unit produced the temperature refrigerating gas lower than gas temperature in the hothouse, and regulate the influx that refrigerating gas flows into hothouse within a certain period of time jointly by air supplying part, so as rapider, replace dry indoor gas effectively.
When the high side temperature that detects cooling unit when described state-detection portion was lower than set point of temperature (T2), then the refrigerating gas replacement process finished (OFF), detects high side temperature again until test section and is higher than set point of temperature, then restarts said process.
As above, by the refrigerating gas replacement process is controlled in the detection of cooling unit component parts running state parameter, can guarantee that air reduces temperature through low temperature parts (for example evaporimeter) before entering hothouse and owing to the freeze drying effect reduces water content.Thereby can in refrigerating gas replacement process and device, remove the humid air in the drying device in the hocketing of gas heating process fast, the drying effect of increase drying device.
＜weight detecting portion 〉
Drying device of the present utility model can further have weight detecting portion, it is for detection of the weight of loaded article in the described hothouse, and by control part detected weight and predetermined weight are compared, regulate refrigerating gas influx within a certain period of time in the refrigerating gas replacement process thus.

[refrigerator with drying device]
Next, the refrigerator that possesses drying device of the present utility model is carried out following detailed description.
As shown in figure 13, refrigerator 1 of the present utility model is indirect cooling refrigerator, and it comprises refrigerating chamber 2, refrigerating chamber 3, drying device 4 and other chamber 5, and described refrigerating chamber 2 has refrigerating-chamber door 22.Described drying device 4 is arranged in the refrigerating chamber 2, and it possesses hothouse 10, cooling unit 20, air supplying part 21 and control part, test section (not shown).A side of described hothouse 10 (side of the rear wall of close refrigerating chamber) is provided with air port 13, and another side relative with it (near the side of refrigerating-chamber door 22) is provided with air port 14.And described air port 14 also has the open-close lid 14a that covers it.And drying device 4 of the present utility model is when being used for refrigerator 1, and its cooling unit 20 shares with the refrigeration part of refrigerator 1, and air port 13 is positioned on the wind path of refrigerator.
After putting into article in the hothouse of refrigerator, the alternate run of gas heating process in the refrigerating gas replacement process in the control part control hothouse and the hothouse is in order to realize the dry-storage effect.
Particularly, cooling unit 20 produces the refrigerating gas that temperature is lower than gas in the hothouse 10.For example, gas temperature for example is 1 ~ 9 ℃ in the hothouse 10, and at this moment, cooling unit 20 generation temperature are the refrigerating gas below-10 ℃.This refrigerating gas shown in arrow among the figure, through the valve 21a of air supplying part, via air port 13, flows in the hothouse 10 under the running of air supplying part 21 promotes.At this moment, owing to have air pressure difference inside and outside the hothouse, thereby make the open-close lid 14a in described air port 14 open, higher gas (for example temperature is 1 ~ 9 ℃ the gas) gas that is cooled (for example temperature is the refrigerating gas below-10 ℃) displacement 14 outflows from the air port of original relative humidity in the hothouse.
After the refrigerating gas replacement process finished, air supplying part 21 shut down, and its valve 21a closes, and, owing to do not have refrigerating gas to continue to enter in the hothouse 10, so open-close lid 14a closes under the gravity effect.At this moment, described hothouse becomes closed environment.
And then refrigerating gas (for example temperature is the refrigerating gas below-10 ℃) carries out gas heating process in the hothouse in this closed hothouse.Namely, because hothouse 10 is made of Heat Conduction Material, the heat conduction takes place and carries out heat exchange in this refrigerating gas and hothouse external environment (being about 1 ~ 9 ℃), make the refrigerating gas temperature rise naturally, its relative humidity reduces (for example dropping to RH15 ~ 20%), and the gas after should heating up also increases gradually for the saturation of steam, thereby can the article of putting in the hothouse be dehumidified, and realizes desiccation.
As shown in figure 14, refrigerator of the present utility model comprises refrigerating chamber 2 and refrigerating chamber 3, and described refrigerating chamber 2 has refrigerating-chamber door 22.Consider under the situation that refrigerating-chamber door 22 is opened, refrigeration stops, original gas in the refrigerating chamber is because the extraneous gas temperature that flows into of comparing is low and density is big, therefore sink than cold air and also finally flow out from the refrigerating chamber below, flow into the higher gas of extraneous relative temperature from the refrigerating chamber top simultaneously, cause the relative lower area of temperature of refrigerating chamber upper area higher, so the maintenance that hothouse is unfavorable for low-temperature condition in the hothouse is set, and the gas of extraneous relatively-high temperature high humidity enters the back easily in the surperficial dewfall that forms of the hothouse of relative low temperature from the refrigerating chamber top above refrigerating chamber; The cooling unit of the more close generation refrigerating gas of refrigerating chamber lower position in addition, the low-temperature condition of refrigerating gas easier maintenance before flowing into hothouse like this; At last, the refrigerating chamber below also is the position of most convenient consumer accessing article.Consider more than comprehensive, preferably hothouse 4 is arranged on the below of refrigerating chamber 2.
And, a side of the hothouse of drying device 4 (side of the rear wall of close refrigerating chamber 2) is provided with air port 13, and another relative side (near the side of refrigerating-chamber door) is provided with another air port 14, thus, by the cooperation of the wind path of cold air in air port 13 and air port 14 and the refrigerator, make that the refrigerating gas replacement process in the hothouse can effectively carry out.
Following with reference to Figure 15, for of the present utility model after putting into article in the hothouse of refrigerator, if control part is judged dry indoor relative humidity and is higher than critical humidity, then control the alternate run of gas heating process in the interior refrigerating gas replacement process of hothouse and the hothouse, below be specifically described.

About gas temperature in the hothouse, because the temperature of the refrigerating gas that flows in the hothouse is far below original gas in the hothouse, and the higher gas of original temperature replaced to hothouse, and therefore, dry indoor temperature descends fast.
In time, about the refrigerating gas replacement process, for finishing the state of (OFF), at this moment, cooling unit and then air supplying part all shut down at t2, and do not have refrigerating gas to continue to flow in the hothouse this moment, is in closed environment in the hothouse.
About gas temperature in the hothouse, owing to carry out gas heating process in the hothouse, flowed into the interior refrigerating gas of hothouse owing to heat up naturally with surrounding environment generation heat exchange, this temperature-rise period is comparatively slow.Owing to gas heating expands, therefore reduced dry indoor relative humidity, thereby realized drying effect.
At t3 in the time, about the refrigerating gas replacement process, still for finishing the state of (OFF).About gas temperature in the hothouse, then be in poised state.At this moment, judge whether subcritical humidity of dry indoor relative humidity by control part, if dry indoor relative humidity does not also have subcritical humidity, the control part control drying device process that enters next t1 and t2 then.If dry indoor relative humidity has been lower than setting, then control part is judged this t3 time of continuation, is increased to more than the critical humidity again until dry indoor relative humidity.
