If the chamber of compressor 11 will be set as compressor room 26, then in this compressor room 26 compare with compressor 11 above, drain pan 27 is set.The bottom of the top of this compressor room 26 and cooling chamber 10 is communicated with through pipe arrangement 28.
At the rear side wind path of refrigerating chamber 2 one 12 is set wind path and the air cleaning member 29 that cold air passes through is being set.Fig. 2 has put down in writing the structure of this air cleaning member 29 in detail.Air cleaning member 29 roughly is distinguished into, and is comprised of upside spatial portion 30 and lower side space section 31 these two structures.Upside spatial portion 30 is that cold air is at the structure of the internal flow of the basket 32 that forms this space segment, downside in the side is arranging inflow entrance 33a, 33b, upside in the side is arranging flow export 34a, 34b (among Fig. 2, having omitted the record of inflow entrance 33b, flow export 34b).On these inflow entrances 33a, the 33b and the position between flow export 34a, the 34b of upside spatial portion 30, installation portion 35 is outstanding from basket 32, by filter 36 being arranged on this installation portion 35, becomes the structure that upside spatial portion 30 is divided into two.In the upside spatial portion 30 of being cut apart by installation portion 35 and filter 36, also at the spatial portion that has configured inflow entrance 33 light source 37 is set.In addition, because make the structure of built-in light source 37, so basket 32 makes the material of light transmission.
The lead-in wire 38 of light source 37 extends to downside spatial portion 31, is connected with connector 39 in lower side space section 31.In addition, still in lower side space section 31 also set temperature sensor 40, the lead-in wire 41 of this temperature sensor 40 converges with the lead-in wire 38 of light source 37, is connected connector 39.This connector 39 directly and the main body distribution of refrigerator 1 (not shown go out) tie lines.Like this, need respectively the situation of connector intensive script light source 37, temperature sensor 40 and be a connector 39, accordingly, cut down number of spare parts, reduced cost, and, so that air cleaning member 29 is easy to the installation tie lines operation of refrigerator 1.
The assemble method of the backplate 17 when this air cleaning member 29 is installed in expression be Fig. 3.Air cleaning member 29 between the back side and backplate 17 of the inboard of refrigerating chamber 2, the basket of air cleaning member 29 32 be arranged on the backplate 17 window section 42 in opposite directions.
Fig. 4 is the figure that expression is arranged on the wind path structure on the backplate 17 of refrigerating chamber 2.The face that is provided with this wind path arranges in the mode towards the inside of refrigerator 1 side, accordingly, forms the rear side wind path section 12 is set.The basic structure of this backplate 17 is as follows, by the panel 43 that is provided with a plurality of blow-off outlets for blow out cold air to refrigerating chamber 2, by being arranged on this panel 43, and the opening of the groove of the pipeline constituent part 44 that the foamed styrene etc. that is formed with groove forms, not shown this pipeline constituent part 44 of obstruction, and the seal member that forms pipeline (wind path) consists of.Among this figure, be installed in the state on the backplate 17 by representing air cleaning member 29, represent the relation of wind path and air cleaning member 29, the below illustrates with figure.
Wind path is by the wind path 45 that is communicated with cooling chamber 10 (among Fig. 4 not shown go out), the wind path 46 that separates to the left and right from this wind path 45,47 (be seen as from door 6 sides of refrigerating chamber 2 about opposite), (be followed successively by wind path 48 from branch's side from the wind path of these wind path 46 further branches, 49,50), (be followed successively by wind path 51 from branch's side from the wind path of wind path 47 further branches, 52,53), the wind path 54a on the right side of the cold air flow of inflow air cleaning member, the wind path 54b in the left side of the cold air flow of inflow air cleaning member, the wind path 55a on the right side of the cold air flow that flows out from air cleaning member 29, the wind path 55b in the left side of the cold air flow that flows out from air cleaning member 29 consists of.Wherein, at wind path 48 blow-off outlet 56 is being set, the height blow-off outlet 57 identical with this blow-off outlet is arranged on the front portion of wind path 51.Equally, in wind path 49,52 front portion blow-off outlet 58,59 is being set, in wind path 50,53 front portion blow-off outlet 60,61 is being set.In addition, the blow-off outlet of wind path 55a doubles as the blow-off outlet 62 of wind path 46, and the blow-off outlet of wind path 55b doubles as the blow-off outlet 63 of wind path 47.In addition, also can make wind path 55a, 55b and wind path 46,47 and collaborate again blow-off outlet 62,63 structures that link rear and to refrigerating chamber 2.So, can one side the impact of the pressure loss of refrigerating chamber cooling air duct main flow be suppressed at Min., one side is drawn the ability of filter 36.
In further detail explanation centered by the cold airflow in the refrigerating chamber 2 of the refrigerator 1 that consists of in the above described manner.As shown in Figure 1, because the freeze cycle that is made of the cooler 23 of the function of compressor 11, the not shown condenser that goes out, performance evaporimeter, the temperature of the air in the cooling chamber 10 reduces.The air of this low temperature, that is, cold air is carried to each chamber by pressure fan 24.Wherein to the cold air of refrigerating chamber 2 according to the temperature that is detected by temperature sensor 40, behind refrigerating chamber air door 64 adjust fluxes, flow into the rear side wind path section 12 be set.At this rear side wind path section 12 is set, as shown in Figure 4, in wind path 46 and wind path 47 diffluences from wind path 45 branches in the downstream that is arranged on refrigerating chamber air door 64, one side is given cold air each the branch's wind path 48,49,50,51,52,53 that arranges in the way, and one side is from blow-off outlet 62,63 to refrigerating chamber 2 interior outflows.From the cold air of these branch's wind paths from being arranged in refrigerating chamber 2, to see highly roughly the same blow-off outlet 56,57 to refrigerating chamber 2 interior inflows, for example, with the food on the support 16 etc. without omitting the ground cooling.Equally, from being arranged to see that in refrigerating chamber 2 highly roughly the same blow-off outlet 58,59, blow-off outlet 60,61 also cool off the food on each support etc.In addition, owing to also having support can change the refrigerator of the mode of height, so, not necessarily always have blow-off outlet in the central authorities of support and support from the wind path 56 to 61 of their branches.
On the other hand, although the part of the cold air that flow at wind path 50,53 is from above-mentioned blow-off outlet 60,61 to refrigerating chamber 2 interior outflows, but other pass through wind path 54a, 54b, flow into to inside from inflow entrance 33a, the 33b of air cleaning member 29, the cold air that is cleaned flows at wind path 55a, 55b, with flowing next cold air from blow-off outlet 62,63 to refrigerating chamber 2 interior outflows from wind path 46,49.
Like this, because will be communicated with from the wind path 50 of main air flow 46,47 branches, 53 blow-off outlet 60,61 more anterior wind path 54a, 54b and air cleaning member 29, so, the mesh of filter 36 blocks, the such problem of position deviation of filter 36 even produced, and also can guarantee cooling capacity in the case.
Purify being constructed as follows of cold air by air cleaning member 29.The cold air that inflow entrance 33a, 33b from the two sides in opposite directions of the basket 32 that is arranged on air cleaning member 29 flow into upside spatial portion 30 is by filter 36, and accordingly, bacterium, stink composition are removed.From this filter 36, at the upstream side of cold airflow the light source 37 that is made of LED is being set.Although light source 37 has several effects,, one of them is the detergent power of performance filter 36.Be carried in the material on the filter 36 visible-light-responsive photocatalyst is arranged.Visible-light-responsive photocatalyst is from only different by the photochemical catalyst of the photolytic activity of general ultraviolet wavelength, and the composition in the cold air is also by the photolytic activity of visibility region wavelength (for example, ionization, freeization).Accordingly, bacterium, the oxidized decomposition of foul smell composition (organic substance).Specifically, can list and titanium oxide is carried out nitrogen mix, be coupled to the material of titanium oxide etc. with the material of the part of nitrogen replace oxygen, with the compound of platinum or iron etc.That is, even be by light source 37, in the material of filter 36 carryings, particularly visible-light-responsive photocatalyst is by the material of activate.In addition, also can make filter 36 carrying antioxidants.Antioxidant is by the oxidation of antioxidant own, suppresses to adhere to the material of the oxidation of object, as the antioxidant take food as object, can list L-AA, Rosmarinus officinalis extract matter etc.At least a above by filter 36 carryings among these, by passing through of cold air, antioxidant is emitted in refrigerating chamber 2 from the filter desorb, arrives the food of being stored, and obtains the oxidation inhibition of food.
In addition, filter 36 is with the material of the intensive Cheng Mianzhuan of organic material nonwoven, makes the material of the rivel shape that organic material nonwoven sheet extends, turns back maybe will make the material of supporting body sintering on the inanimate matter pottery make the undulatory material of honeycomb etc., and base material, form can be selected arbitrarily the material that determines according to the wind path pressure loss or irradiation scope transmitance etc.
What can list as other the effect of light source 37 is function as illumination.As mentioned above, because air cleaning member 29 so that showing for the modes in the refrigerating chamber 2 of the bending of the basket 32 that the material that light sees through from the window section 42 that is covered by the transparent cover of upholstery of backplate 17 is made arrange, so, can illuminate the rear side in the refrigerating chamber 2 on a large scale.Generally, the scope of illumination in order to strive for shining in the refrigerating chamber mostly is arranged on the ceiling face, or is arranged on the side.Although the situation of the inside that is arranged on refrigerating chamber is also arranged,, in this situation, enlarge range of exposures by the illumination that top to bottm arranges from refrigerating chamber.In the invention of present embodiment, although at the summary upside of comparing with the central portion of the wall at the rear of refrigerating chamber light source 3 is set,, this is the illumination of assisting.Main illumination is arranged on ceiling face, side.Like this, by the inside side in refrigerating chamber 2 auxiliary illumination is set, can accesses the effect of easily seeing food of being placed on indoor the inside etc., in addition, also have the function of the color that correctly shows backplate 17.General in the situation that commodity are set forth at the household electrical appliances sales field, in order to see commodity more charmingly, mostly at periphery special-purpose ligthing paraphernalia is set, in order to make luminous energy shine commodity from various angles.Especially in the situation that is nearest refrigerator, owing to not only being conceived to outward appearance, also be conceived to configuration, color in the storeroom such as refrigerating chamber, so, be provided for separately illuminating the illumination in the case, and only compare for the situation of case intraoral illumination, the situation increase that shows with bright state.Therefore, if after purchase, only make to see with the case intraoral illumination, then compare the example of feeling dark with situation about seeing in the paving also a lot of at home.As the illustrated invention of present embodiment, only by make with auxiliary light source 37 backplate 17 around bright, just can illuminate in the storeroom to see the roughly the same light and shade of tone in the paving, can alleviate inharmonious sense.
In addition, light source 37 is necessary to radiate and contains the light that can obtain by the wavelength that excites of the visible-light-responsive photocatalyst of filter 36 carrying.Specifically, can express for example near the LED of the look that turns blue (the wavelength 470nm) light.In addition, light source 37 be so long as can make the article of the luminous ormal weight of light of the wavelength that excites that can obtain catalyst get final product, and for example, also can be the LED etc. of white (based on blue and yellow combination etc.).In addition, the quantity of light source is not had special provision, for luminous ormal weight, for example, can carry a plurality of LED, in addition, can make the illuminant colour of each LED be not homochromy combination yet.Concrete structure as light source 37, can express for example following structure, namely, to encapsulate the substrate of LED of shaped like chips on transparent or housing cylindraceous by the moulding such as resin that see through light, engagement by groove etc. remains on assigned position, takes out lead-in wire 38 from the open end of transparent shell, this open end is by the high sealings such as seal member of water preventing ability, the measure of the LED breakage that implemented Antidewing, freeze etc. caused.
In addition, in the refrigerator 1 that consists of like this, by being arranged on the control substrate 66 at the back side, according to the testing result that is arranged on the temperature sensor 67a in the refrigerating chamber 4, the operating condition of control compressor 11 and pressure fan 24 is in order to become set point of temperature, according to the testing result that is arranged on the temperature sensor 67b in the switching chamber 3, control switching chamber air door 68 is in order to become set point of temperature.
The cold airflow that is cleaned in the refrigerating chamber 1 is as follows.The cold air that blows out from blow-off outlet 62,63 flows between the ceiling face of support 13 and refrigerating chamber 2, to door 6 side flow.Then, if collide with door 6, then change direction and flow for the bottom surface 18 to refrigerating chamber 2, carry to vegetable compartment 5 from the cold air return port 65 that is arranged on the bottom surface.
Like this, blow out cold air from the blow-off outlet 62,63 of the superiors, under the state of having closed door 6, form along the cold airflow from top to bottom of door 6, accordingly, outwards spill when door 6 is opened, the user smells an offensive odor or the Quilt with air conditioning that is bonded on the health purifies.In addition, owing in the wind path with cold air air-supply, air cleaning member 29 being set, so, the cold air after just purifying is blown out from blow-off outlet 62,63, therefore, to compare with purification mechanism being arranged on the situation that cold air returns on the wind path, the efficient of health aspect is high.In addition, although in the invention of relevant present embodiment, the cold air that the is cleaned blow-off outlet 62,63 from the superiors is blown out,, according to the size of refrigerator, can not be the superiors also.
In addition, filter 36 using visible light responsive photocatalysts, used visible light as the light source 37 that excites catalyst, accordingly, even the light of light source 37 is exposed in the refrigerating chamber 2, also there is no need to worry the impact on food, human body, can carry out to identify to the user configuration of the position of lighting of the light source 37 that excites catalyst.Accordingly, the light of light source 37 can be used flexibly as the illumination of storeroom, makes the food that is saved good-looking, or make the fault of light source 37 understanding, judge easily.Man-hour, the efficient of the maintenance in the time of in addition, can improving light source failure, replacing operation.Have, in the situation that make filter 36 carry antioxidant, this antioxidant is released again, and the probability that reaches foodstuff storing improves, and therefore, the antioxidation of food improves.
Above-mentioned cold airflow is the cold airflow under the door 6 pent states, still, if with the amount of cold air, the control sophisticated category of light source 37, then imagine three patterns.First mode is when detecting door 6 by the member of the open and-shut mode of detecting gate 6 (not shown go out) and opened, so that the pattern that light source 37 is lighted and the mode of out-of-blast machine 24 is controlled.With the opening action of door 6 light source 37 is lighted be used to making the user easily see food in the refrigerating chamber 2 etc.But filter 36 has carried in the situation of antioxidant at the same time, by out-of-blast machine 24, the antioxidant situation that cold air flows out in case that is dispersed in the refrigerating chamber can be limited in Min. outside case.In addition, by opening door 6, cold air temperature rises in the case, atmospheric density by filter 36 improves, and becomes the tendency that the desorption quantity of the bacterium that is adsorbed on the filter 36, stink composition increases, still, light by making light source 37, excite catalyst, promote the bacterium of filter 36, the decomposition of stink composition, simultaneously, on the other hand, out-of-blast machine 24 suppresses the amount by the cold air of filter 36, reduces the desorb of bacterium, stink composition.
In the second pattern, stop in the testing result according to temperature sensor 67 in the situation of control of compressor 11, near heater 25 energisings the cooler 23, dissolve be attached on the cooler 23 the frost and catchment to drain pan 27, in the situation that heat extraction during by compressor 11 running is vaporized (in the so-called defrosting course of action), if out-of-blast machine or close air door, then cold air temperature rises in the case.During this period by making light source 37 luminous, anti-bacteria, stink composition are from the desorb of filter 36.In addition, also can be with first mode and the second mode combinations.
Three-mode is when detecting door 6 by the member of the open and-shut mode of detecting gate 6 (not shown go out) and open, and light source 37 is lighted, and makes pressure fan 24 be the pattern of operating condition.Because, with the opening action of door 6 light source 37 is lighted be used to making the user easily see food in the refrigerating chamber 2 etc., if the switching of short time, the example that does not then relate to out-of-blast machine 24 is a lot.Therefore, also can make control substrate 66 have timer function, according to the time that door 6 is opened, switch first mode and three-mode.
In addition, can also be in reconcilable limit with these first to the three-mode combination with one another.
Fig. 5 is the cutaway view of the switching chamber of relevant embodiments of the present invention 2, but Fig. 6 is the design of part figure of dynamic sensor section of the switching chamber of relevant embodiments of the present invention 2.In addition, to having the structure of the function identical with embodiment 1, mark identical symbol.
The wind path that switching chamber 3 will be passed through from the cold air of cooling chamber 10 is arranged on the inside side, at the branch point of this wind path switching chamber air door 68 is set.This switching chamber air door 68 possesses the ceiling face of switching chamber of being formed on 3, cross drawer 20, the back side wind path dividing plate 72 that the back side wind path 71 that blows out at the ceiling wind path dividing plate 70 that nearby arranges to the indoor ceiling wind path that blows out 69 of door 7, from the back side of switching chamber 3 to drawer 20 arranges, these dividing plates are can be by the drive division 73 independent binary channels air doors that open and close each dividing plates.Though not shownly go out, by with the outer guidance panel of case etc., the dividing plate that air door is correspondingly carried out in the setting in the switching chamber 3 of selecting with the user opens and closes to carry out the air quantity adjustment, is controlled at the regulation design temperature.By making such wind path structure, for example, can also be behind input food, correspondingly simultaneously adjust cooling capacity with the outer guidance panel operation of user's case, one side is carried out the food cooling, makes the moisture in the food become the supercooling state, then, increase by cooling capacity, give and low temperature stimulation, can make supercooling remove and freeze.Have again, can also preserve stable state by judging, inhibition makes the up and down amplitude of fluctuation of food and environment temperature as far as possible little to the minimal cooling air quantity of necessity, prevent to food frost, food product refrigeration damage, the freezing preservation of dry, oxidation etc.
Use Fig. 6, the structure of driver element 78 is described.The shell of driver element 78 by possess two window sections 79 arranged side by side, 80 cylinder section 81 and lid 82 consist of.In cylinder section 81, packaged chip LED and the light source 83 that consists of and the temperature sensor 84 that is made of the infrared ray sensor that detects the temperature in the drawer 20 are housed in respectively the position in opposite directions with window section 79,80.This temperature sensor 84 is embedded in temperature sensor holding member 85, and temperature sensor holding member 85 links with the output shaft of motor 86.On the other hand, light source 83 with by transparent or make the light source holding member 87 of molding resin material of light transmission chimeric, link with temperature sensor holding member 85.Motor 86 is such as be the motor that drives by stepper motor etc. in the predetermined angular scope.Axle by this motor 86 drives, and temperature sensor 84 and light source 83 can drive simultaneously.The lead-in wire of making light source 83, temperature sensor 84 and motor 86 by intensive in a connector 88, by the structure of the main body distribution tie lines of this connector and refrigerator 1.Although temperature sensor 84 detects the temperature of food by infrared ray sensor,, merge processing by the testing result with the temperature sensor 67b that measures the air themperature in the switching chamber 3, can carry out more high-precision temperature detection.For example, also can be used as behind input food, correspondingly simultaneously adjust cooling capacity with the outer guidance panel operation of user's case, one side is carried out the food cooling, make the moisture in the food become the supercooling state, then, increase by cooling capacity, give and low temperature stimulation, supercooling is removed and the switching chamber of the structure that the high-quality success rate of freezing freezed is improved.In addition, because driver element 78 can be rotated in the amount of the angle shown in two arrows among Fig. 5, so, for the whole zone of drawer 20, can carry out temperature detection by temperature sensor 84.In addition because driver element 78 can big angle rotary like this, so, even the LED that directive property is strong as light source, light also can arrive in the switching chamber 3 on a large scale, can improve user's identity.
By being arranged on the light source 83 on such driver element 78, the visible-light response type catalyst that is carried by filter 76 is excited, and has promoted by the bacterium in the cold air of filter 76, the decomposition of stink composition.In addition, because filter 76 is also carrying antioxidant, so, also carry out emitting of antioxidant.
Like this, because at the ceiling face, the blow-off outlet 75 of the cold air that the part setting of especially close door 7 is cleaned, so, the cold airflow that the cold air that blows out from blow-off outlet 75 forms from top to bottom along door 7 under the state of having closed door 7, therefore, outwards spill when door 7 is opened, the user smells an offensive odor or the Quilt with air conditioning that is bonded on the health purifies.In addition, because in the wind path with cold air air-supply, be provided with filter 76, so, the cold air after just purifying is blown out from blow-off outlet 75, therefore, to compare with purification mechanism being arranged on the situation that cold air returns on the wind path, the efficient of health aspect is high.
With regard to lighting of light source 83 moved, same with embodiment 1, consider a plurality of patterns.For example, have in the compressor stopped process and the defrosting course of action in the pattern lighted, when light source 83 is lighted, action by driver element 78, make the craspedodrome axle of light source 83 towards the direction of filter 76, accordingly, can also obtain exciting of catalyst, with bacterium, stink composition (organic substance) oxidation Decomposition.Have again, beyond during filter 76 irradiations, shine towards drawer 20 directions by the craspedodrome axle that makes light source 83, can also improve the visual effect as the illumination in the drawer 20.
