Description
The present invention relates to begin to isolate successively the electric refrigerator for freezing and cold storage that is formed with refrigerating chamber, refrigerating chamber and vegetable compartment, particularly relate to and to transport to the structure of the cold air service duct of refrigerating chamber and vegetable compartment from the cold air of cooler from the top of body interior.
Top from body interior nearest electric refrigerator for freezing and cold storage does not resemble in the past begins to isolate successively formation refrigerating chamber, refrigerating chamber and vegetable compartment, but considers the frequency of use, begins to isolate successively formation refrigerating chamber, refrigerating chamber and vegetable compartment from the top.Yet, the refrigerating chamber that adopts the electric refrigerator for freezing and cold storage of this structure to be provided with will to transport to refrigerating chamber from the cold air of cooler with the cold air service duct, be that refrigerating chamber is used the cold air outlet, with the vegetable compartment of cold air being transported to vegetable compartment with the cold air service duct, be that vegetable compartment is used the cold air outlet, the vegetable compartment of using the cold air return road and making the cold air of supplying with vegetable compartment return cooler with the refrigerating chamber that makes the cold air of supplying with refrigerating chamber return cooler is used the cold air return road.
But, the cold air outlet and the cold air return road of refrigerating chamber and vegetable compartment special use can make cold air path complicated because being set, so in the prior art, as shown in figure 12, by refrigerating chamber is communicated with vegetable compartment 2 with cold air return road 1 with the cold air service duct of refrigerating chamber usefulness cold air return road 1 as vegetable compartment, the cold air of supplying with refrigerating chamber 3 is carried to vegetable compartment 2, then turned back in the cooler that is located at refrigerating chamber 5 back sides with cold air return road 4 by vegetable compartment from the cold air of refrigerating chamber 3.
But, elevate the temperature after refrigerating chamber, circulating from the cold air of refrigerating chamber 3, so can not fully cool off vegetable compartment 2 to vegetable compartment 2 supplies.Therefore, in the prior art, form vegetable compartment at above-mentioned refrigerating chamber on cold air outlet 6 and shunt service duct with cold air, make with cold air shunting service duct by this vegetable compartment and to supply with refrigerating chamber from cooler and flow into refrigerating chamber with cold air return road 1, thereby the cold air temperature of supplying with vegetable compartment 2 is descended with the part of the cold air in cold air outlet 6.Opening flat 3-267677 communique, spy the spy, to open flat 4-288466 communique etc. disclosed be the electric refrigerator for freezing and cold storage with above-mentioned formation.
In Figure 12,6a is at the refrigerating chamber cold air blow-off outlet that forms on the cold air outlet 6,7 are provided in a side of the damper of refrigerating chamber with the bottom in cold air outlet 6, by the switch motion of this damper, can use the amount of the cold air of cold air outlet 6 conveyings to refrigerating chamber from cooler with control in the air-supply arrangement in circulating cold air.
In addition, back at refrigerating chamber is formed with cooling chamber, to transport to refrigerating chamber from the cold air that is located at the cooler in the cooling chamber by being located at refrigerating chamber cold duct behind, simultaneously, will distribute from the cold air of above-mentioned cooler and be fed to following vegetable compartment and in the ice greenhouse that refrigerating chamber bottom zoning forms by being located at cooling chamber cold air allocation member behind.
In this case, utilization be formed at refrigerating chamber behind and the vegetable compartment that is communicated with above-mentioned cold air allocation member supply cold air with cold air path to vegetable compartment, in addition, also constitute and in refrigerating chamber and ice greenhouse, to suck this vegetable compartment with in the cold air path by the cold air after the circulation, so just cold air can be imported and just make after the vegetable compartment cold air return cooling chamber and cool off each chamber again, so circulation.For example the spy opens flat 4-288466 communique and just discloses the electric refrigerator for freezing and cold storage with said structure.
In addition, the vegetable compartment that communicates with the cold air allocation member forms by being embedded in the pipeline that filling in the freezer compartment wall portion of foam-thermal insulation with cold air path, this pipeline extends along the above-below direction that is in the refrigerating chamber between refrigerating chamber and the vegetable compartment, and project upwards at this upper and lower, be communicated with the refrigerating chamber of top and the vegetable compartment of below.It is the pipeline that the resin pipes about 3mm forms by thickness for example that in the past this kind of vegetable compartment adopts with cold air path, or adopts the pipeline of being made by foamed materials such as foam styrenes.
In the electric refrigerator for freezing and cold storage in the past of cool-air feed passage with said structure, as shown in figure 12, be formed at from the Quilt with air conditioning of refrigerating chamber 3 after refrigerating chamber above the spaced walls 8 of isolating refrigerating chamber 3 and refrigerating chamber 5 anterior sucks with the cold air inlet 1a in cold air return road 1, flow to the behind of refrigerating chamber 5 by inside cold air path 1b in the formation of the inside of spaced walls 8, then, again by being formed at refrigerating chamber 5 behind cold air path 1c behind, and blow out to vegetable compartment from the cold air blow-off outlet 1d that is formed at vegetable compartment 2 end faces.
Owing to make from the cold air of refrigerating chamber 3 inside by spaced walls 8 and blow to vegetable compartment 2 again, so that the structure complicated of spaced walls 8, so not only make the shaping difficulty of spaced walls, and owing to make cold air that temperature from refrigerating chamber raise by spaced walls inside, in order to keep the thermal insulation of spaced walls 8, must thicken the thickness of spaced walls 8, thereby have the high problem of cost.

In Fig. 1, Fig. 2, the 9th, have the body (hereinafter referred to as body) of heat insulating construction, this body 9 is to form by filling foam-thermal insulation 12 between the interior case 10 of opening in front and the outer container 11, the 13rd, be used for the insulated door of switch refrigerating chamber 3,14 are provided in a side of the drawer of the double as insulated door on vegetable compartment and the refrigerating chamber, the 15th, frame.
In the bottom of above-mentioned refrigerating chamber 3, go out an ice greenhouse 16 by thermal insulation frame 15a zoning, between this ice greenhouse 16 and interior case 10, be provided with the damper 17 of damper 7 and being communicated with the cold air outlet in internal configurations with refrigerating chamber.This damper chamber 17 is formed by heat-insulating materials such as foam styrenes, and be formed at the inside of side's cold air allocation member 18 outstanding, that have thermal insulation in the bottom of refrigerating chamber 3, in addition, dock with above-mentioned cold air allocation member 18 rear end of frame 15a, thereby make ice greenhouse 16 be formed at the place ahead of cold air allocation member 18.
Rear portion at refrigerating chamber 5, go out cooler chamber 19 by zoning between space bar 19a and the interior case, in this cooler chamber 19, disposing cooler 20 and the circulating cold air air-supply arrangement 21 that is used for the circulating cold air from this cooler 20 is fed to refrigerating chamber 5, refrigerating chamber 3 and vegetable compartment 2.
In addition, as shown in Figure 3, the sidepiece in above-mentioned cooler chamber 19 is provided with the 1st pipeline 22 that is communicated with damper chamber 17, from the cold air of cooler 20 by circulating cold air with air-supply arrangement 21, transport to damper chamber 17 via the 1st pipeline 22.In addition, the opening in damper chamber 17 1 sides of the 1st pipeline 22 comes gauge tap by damper 7.
In addition, be formed with and can transport to the ice greenhouse cold air service duct 23 of icing greenhouse 16 with the part of the cold air in cold air outlet 6 with being fed to refrigerating chamber in the inside of above-mentioned cold air allocation member 18, this ice greenhouse is formed on the front of cold air allocation member 18 with the cold air blow-off outlet 24 of cold air service duct 23.
As shown in Figure 2, be located at and formed refrigerating chamber between the space bar 25 at refrigerating chamber 3 rear portions and the interior case 10 with cold air outlet 6, cold air from cooler 20 blows to refrigerating chamber 3 from the cold air blow-off outlet 6a that is located on the above-mentioned space bar 25, and as shown in Figure 3, blow to ice greenhouse 16 from the cold air blow-off outlet 24 that forms in cold air allocation member 18.In addition, in Fig. 3,6A is the multiple-way duct that is configured between interior case 10 and the space bar 25 and is formed with refrigerating chamber usefulness cold air outlet 6.
In addition, inside in above-mentioned cold air allocation member 18, formed vegetable compartment with shunting cold air service duct 26 from refrigerating chamber with cold air outlet 6 differences, as shown in Figure 1, can blow out with cold air return road 27 from the refrigerating chamber on the end face that cold air blow-off outlet 27a is located at vegetable compartment 2 by the part of this vegetable compartment with the cold air of shunting cold air service duct 26 conveyings.
In addition, as shown in Figure 4, bottom in that side that staggers with damper chamber 17 of cold air allocation member 18 fronts is formed with cold air inlet 28, this cold air inlet 28 promptly is the inlet of refrigerating chamber with cold air return road 27, is used for being drawn onto and using cold air return road 27 with the refrigerating chamber that the cold air service duct uses as vegetable compartment by flowing through the cold air that comes in the gap that forms between the box body 16a in ice greenhouse 16 and the spaced walls 8 again after blowing out from refrigerating chamber 3 and ice greenhouse 16.
Like this, from refrigerating chamber 3 and the cold air that blows out of ice greenhouse 16, shown in the arrow A among Fig. 5, be introduced into refrigerating chamber with the cold air return road 27 from cold air inlet 28, and with figure in conflux in the space S of confluxing that in cold air allocation member 18 as shown in Figure 6, forms with the cold air in cold air outlet 26 from vegetable compartment shown in the arrow B, sucked by the top opening 27b that is communicated with the space S of confluxing of refrigerating chamber again, and flow to vegetable compartment 2 with cold air return road 27.
In addition, cold air allocation member 18 is because can not foodstuff storing, so it belongs to idle space in refrigerating chamber 3 (or ice greenhouse 16), but forms for 2 bursts of space S of confluxing that cold air confluxes by portion within it, just can effectively utilize this idle space.In addition, a side bottom of cold air allocation member 18 is the places that do not take food storage in ice greenhouse 16, forms the storage space that cold air sucting inlet 28 can ensure food at this place.
On the other hand, by refrigerating chamber is arranged on the front of cold air allocation member 18 with the cold air sucting inlet 28 in cold air return road 27, as shown in Figure 1, when forming refrigerating chamber, can make it pass through the inside of spaced walls 8 with cold air return road 27, like this, not only can simplify the structure of spaced walls 8, and the displacement of cold air is shortened, thereby can under the situation of not using large-scale circulating cold air with air-supply arrangement 21, make circulating cold air.As shown in Figure 2, can return cooler chamber 19 with cold air return road 4 from above-mentioned refrigerating chamber by vegetable compartment with the cold air that cold air return road 27 blows out.
In addition, as shown in Figure 7, refrigerating chamber is by forming in the heat-insulating material of resinous pipeline 27A shown in Figure 8 being imbedded the refrigerating chamber rear wall parts with cold air return road 27.This pipeline 27A is configured in the interior case that forms refrigerating chamber and the desired location between the outer container, just with the cooling chamber that is provided with cooler position arranged side by side on, refill the heat-insulating material urethane foam, to form integral body.
With in the past expansion ratio is that 30 to 40 times styrene resin is compared, and this pipeline 27A adopts about 2 to 3 times the low foamed resin of expansion ratio to form.Because adopt the low foamed resin of expansion ratio to form pipeline 27, its resin density just improves, thereby intensity also is improved, thereby can meet the requirements of pipeline 27A to form thermal insulation than in the past the thinner thickness of foam styrene.
Because in the past pipeline 27A is to be that 30 to 40 times styrene resin forms by expansion ratio, so thickness is thicker.Though pipeline 27A of the present invention is thin, but can reach and the similar thermal insulation of pipeline in the past, not only do not need the resin outer cover that plays humidification in the past, but also do not need to use the electric heater that prevents dewfall owing to have sufficient thermal insulation, thereby can reduce number of components and parts, improve packaging efficiency, realize the miniaturization of pipeline.For example, as an example of the thickness of pipeline 27A, can adopt thickness is the slim pipeline 27A of 5mm, and this and thickness are that the thickness of pitch tube of 3mm is approaching.
As previously mentioned, in pipeline 27A, have after refrigerating chamber 3 and the circulation of ice greenhouse 16 cold air and via the vegetable compartment of cold air allocation member 18 with cold air outlet 26, from the direct cold air flow of cooler 20, the former cold air after refrigerating chamber 3 and 16 circulations of ice greenhouse is than the temperature height of the latter's direct cold air, as being transported to vegetable compartment 2 after the cold air mixing that this temperature is different, will reduce cold air efficiency.For this reason, form a kind of pipeline 27B as shown in Figure 9, in this pipeline 27B, be separated to form the cold air path 31B that passes through for the cold air after the circulation in refrigerating chamber 3 and ice greenhouse 16, with make the cold air path 32B that passes through again after via vegetable compartment from the cold air of cooler 20 with cold air outlet 26, so just cold gas stream can be transported to vegetable compartment 2, thereby cool off vegetable compartment 2 effectively.And owing to have damper 7 to strengthen cold airflow, so under the situation of air conditioning quantity deficiency, also can carry the cold air of lower temperature to vegetable compartment, thus can overcome the not enough problem of vegetable compartment cooling.
In addition, this also available foamed resin of pipeline 27B with multi-channel structure of passage 31B, 32B forms simply by means such as extrusion moldings.When using the pipeline 27B of this kind structure, as shown in figure 10, be configured to make the low cold air path 32B that cold air passed through of temperature towards refrigerating chamber it.So just can suppress the hot conductivity of the high relatively cold air path 31B that cold air passed through of 6 pairs of temperature of the low refrigerating chamber of temperature, thereby can prevent that cold air via cold air path 31B from making the inner face dewfall of pipeline 27B.
In addition, if by Figure 11 direction when coming configuring pipes 27C, it is configured to make with the pipeline 27C relative face side of the low cold air path 32C that cold air passed through of temperature towards cooler 20, the hot conductivity that so also can suppress the high relatively cold air path 31C that cold air passed through of 6 pairs of temperature of the low refrigerating chamber of temperature, and also can prevent the inner face dewfall of cold air path 31C, thereby can abolish the use electric heater.
Below explanation has the circulating cold air action of the electric refrigerator for freezing and cold storage of said structure.
