Specific embodiment

Below, referring to figs. 1 through Fig. 6 the first embodiment of the present invention is described.

At first, Fig. 2 shows the main body cover 21 of refrigerator, injects in the space between outer container 22 and interior case (refrigerating chamber that Fig. 2 only shows epimere with the refrigerating chamber in interior case 23 and stage casing with interior case 24) that stoste makes and heat-insulating material foaming and fill up this space.

In the refrigerating chamber 26 that case 23 constitutes in by above-mentioned refrigerating chamber multilayer shelf 27 is set, the feed-tank chamber 29 that chilly locellus 28 and ice machine are used is set at foot.In addition, near the centre of the inboard of refrigerating chamber 26, channel cover 30 is set.Because channel cover 30 is the parts that are used for from the cool-air feed refrigerating chamber 26 of not shown cooling chamber, so have cold gas exhausting outlet 31 accordingly respectively with each layer of above-mentioned shelf 27, go up overleaf, as shown in Figure 1, the passage that forms many passages 32 that extend up and down has been installed and has been formed parts 33.

With it relatively, form groove 34 on the interior case 23 of the internal face that constitutes refrigerating chamber 26, above-mentioned passage forms parts 33 and is contained in this groove 34, and channel cover 30 is installed with itself becoming flat condition.

Fig. 4 and Fig. 5 show above-mentioned channel cover be installed in structure on the case 23, from Fig. 4 and Fig. 5 as can be known, on the ora terminalis of channel cover 30, extend contact site 30a again, and at for example 4 local Elastic Meshing sheets 35 that form as fitting portion, the both side ends of the groove 34 on interior case 23 forms a plurality of conducts by the engaging piece 36 of fitting portion, and each Elastic Meshing sheet and this engaging piece are meshing with each other.On a position of the centre of channel cover 30, form installing hole 37, with a screw 38 insert in this installing hole 37 be threaded onto on the case 23, like this, in just channel cover 30 being installed on the case 23.

Because the groove of interior case 23 34 more shallow (heat-insulating material of main body cover 21 25 residual have thicker adiabatic wall), so it is littler than the thickness T 2 (with reference to Fig. 9) that existing passage forms parts 4 that passage forms the thickness T 1 (with reference to Fig. 1) of parts 33, and its width W 1 is bigger than the width W 2 that existing passage forms parts 4, therefore can guarantee the breathing area of necessity of passage 32, with above-mentioned this relation, the width W 3 of channel cover 30 is big than the width W 4 of existing channel cover 2 also.

Inboard at the foot (chilly chamber 28) of refrigerating chamber shown in Figure 3 26 is provided with valve gear 39 with respect to passage 32.Though do not have detailed icon among this valve gear 39 figure, but under effect, make valve shield 40 actions, the through hole 42 that switch is communicated with cooler chamber (not shown) by Fig. 3 and passage 41 shown in Figure 6 with the air pressure of the variations in temperature in the refrigerating chamber 26 or motor action.Therefore cool-air feed when the temperature in the refrigerating chamber 26 is higher than set point of temperature, and cut-out cool-air feed when being lower than set point of temperature.

This valve gear 39 is to be arranged on like this on the inboard of foot of above-mentioned refrigerating chamber 26: promptly, the damping area that contacts with above-mentioned through hole 42 43 of valve shield 40 points to the case inboard, and cold gas exhausting outlet 44 is positioned on the position in the case outside, and passage 32 is communicated with this cold gas exhausting outlet 44.Under such relation, passage forms their foot of parts 33 and channel cover 30 and can not resemble existing passage and form and stretch out to the case inboard parts 4 and the channel cover 2.

Passage forms parts 33 and engages overlappingly along fore-and-aft direction with respect to above-mentioned valve gear 39, and under such state, valve gear 39 is tightened by the screw 45 that enters from the case inboard and fixes.

Secondly, also show a little groove 46 to the rear cabinet outside in Fig. 1, the passage that this little groove 46 is formed on the groove 34 of above-mentioned interior case 23 forms on the side of parts 33 accommodation sections, is used to hold lead.To after binding, above-mentioned valve gear 39 parts of the connection of passage 32 and the vinylon band etc. that is configured in power circuit substrate 47 (with reference to Fig. 3) the many braided steel wires of lead 48 usefulness partly on back side case outside be contained in this little groove 46.

In addition, in the adiabatic wall of main body cover 21, the back position of the thicker both side ends of the inboard of the groove 34 of case 23 sets the heat release pipe 49 of a part of the condenser of freeze cycle in avoiding.

In addition, Fig. 2 to Fig. 4 also shows the refrigerating chamber 26 illuminating lamp inside the box covers 50 of the topmost that is arranged on channel cover 30.

Under situation about constituting in the above described manner, owing to after the groove 34 on the case 23 that is contained in the internal face that constitutes refrigerating chamber 26 at the passage formation parts 33 that will be positioned at channel cover 30 inboards channel cover 30 being installed on this case 23, so channel cover 30 itself is flatly to be installed on the internal face of refrigerating chamber 26, can not resemble the existing channel cover 2 outstanding in case.So just the dischargeable capacity of holding article in the case can be increased, and a kind of constriction of user can be do not given in appearance.

Under the situation of above-mentioned formation, since channel cover 30 by for the Elastic Meshing sheet 35 of fitting portion and for by the engaging piece 36 of fitting portion in the end engagement is installed on the case 23, even distortion occurs in the end, also can its rectification be installed and fixed by the chimeric of them.Because channel cover 30 can be adjacent to installation from the internal face of refrigerating chamber 26 with lifting up, so outward appearance can be better.And, because this installation mainly is the engagement that utilizes Elastic Meshing sheet 35 and engaging piece 36, only used a screw 38 to install, so installation exercise is more easy, owing to reduced the usage quantity of screw 38, also can reduce cost in addition.

In addition, because engaging piece 36 is so-called tooth root (under cut) shapes that cut, though it is difficult forming on the flat of interior case 23, owing to be formed on the groove 34, so be shaped with 34 formation (generally being vacuum forming) time of this groove easily.As long as the demouldings of this moment etc. are by using the embedded mould that slides towards the center position of groove 34 just can carry out at an easy rate.

Because relatively the valve gear 39 that is used to regulate cold air supply that forms the passage 32 that forms on the parts 33 at passage is installed like this, the damping area 43 of valve shield 40 points to the case inboard, and cold gas exhausting outlet 44 is positioned on the position in the case outside, above-mentioned passage 32 is communicated with the cold gas exhausting outlet 44 of this valve gear 39, so passage form parts 33 and channel cover 30 their foot 33a, 30b and can not resemble existing passage and form and stretch out to the case inboard parts 4 and the channel cover 2.And the foot 30b of channel cover 30 can be to refrigerating chamber 26 yet interior side-prominent, therefore can further increase dischargeable capacity in the case, outward appearance is also better.

It is not to engage overlappingly along the vertical direction as existing passage forms parts 4 with respect to valve gear 39 that passage forms parts 33, but engage overlappingly along fore-and-aft direction, under this state, because by the screw 45 that enters from the case inboard valve gear 39 is tightened and to be fixed, play and strengthen the effect that passage forms the engaging force of parts 33 effectively so produce screwing forces by this screw 45.Even skew appears in the installation site before and after these, they are closely engaged, needn't use seal member just can guarantee that the cold air of supplying with does not leak.

In addition, on the groove 34 of interior case 23, form little groove 46 as the lead accommodation section, be configured in this little groove 46 because will hold along above-mentioned valve gear 39 parts of the connection of passage 32 and the lead 48 that is configured in power circuit substrate 47 (with reference to Fig. 3) part on back side case outside, thus this lead 48 can not be subjected to heat-insulating material 25 the foaming pressure influence and move.And, can not cause the wall portion distortion of the refrigerating chamber 26 outside the channel cover 30, and particularly because do not need existing reinforcement plate just can realize above-mentioned purpose, so can reduce the cost of refrigerating chamber because of this lead 48 places the position that is covered by channel cover 30 yet.

And,, can play the effect that increases dischargeable capacity in the case and beautify outward appearance so can also avoid this little groove 46 outstanding in case because in the darker scope of the groove 34 of interior case 23, form little groove 46.

In addition, because in the adiabatic wall of main body cover 21, the back position of the thicker both side ends of the inboard of the groove 34 of case 23 sets the heat release pipe 49 of a part of the condenser of freeze cycle in avoiding, so can utilize the thicker part of adiabatic wall thickness to prevent the influence of the heat of heat release pipe 49 to the temperature inside the box more reliably.

With relatively above, Fig. 7 shows second embodiment of the present invention, and this Fig. 7 shows to go up in the part adjacent with the groove 34 of interior case 23 (part that is covered by channel cover 30) and forms a little groove 50 towards the forward direction (case inboard) opposite with above-mentioned little groove 46 and replace above-mentioned little groove 46 as the lead accommodation section.

Therefore, by lead 48 being provided in the little groove 50, this lead 48 equally can not be subjected to the influence that heat-insulating material 25 foaming press and moves with above-mentioned.And do not need especially reinforcement plate just can with the above-mentioned the same problem on deformation that solves the wall portion of the refrigerating chamber 26 that lead 48 causes.

In addition, the present invention is not limited to above-mentioned and illustrated embodiment, can be implemented equally as long as can do suitable variation in the scope that does not break away from the present invention's design.
