In addition, drawer type door 4Aa complete cycle be provided with the door gasket 30 be close to the surrounding front surface in the front openings portion of refrigerating chamber 4 (such as, the 1st refrigerating chamber 4A), thus airtight refrigerating chamber 4 prevents the leakage of cold air.But if the cold air in refrigerating chamber 4 arrives door gasket 30, then the easy door gasket 30 via heat-proof quality deficiency produces heat leak with the good outer container of heat transmitting.

Therefore, in the present embodiment, in order to suppress cold air to flow out from the storage case of storage frozen goods to door gasket 30, bag-shaped auxiliary pad 20 is set.In addition, bag-shaped auxiliary pad 20 is compared with product in the past, and structure is more simple, but can flow out from storage case to door gasket side by the cold air effectively in freezing-inhibiting room 4.

Next, the bag-shaped auxiliary pad 20 of Fig. 3 ~ Fig. 4 to present embodiment is utilized to be described.

As shown in Figure 3, auxiliary pad 20 has: fitting portion 21, and it is mounted in the position of refrigerator main body side, and has the intensity that can keep mounting position; Bag portion 22, it is the position forming arcuation contact site 22a, and is planar distortion along the profile of the protuberance abutted.

Fitting portion 21 is preferably and is made up of the resin material of comparison hard of the intensity with regulation, can be easily chimeric with the installation portion 71 that the main body side at refrigerator 1 is arranged and pin thus realize assembling.Bag portion 22 is preferably made up of soft resin material, and be equivalent to when closing the door of drawer type the fore-and-aft direction contact passing in and out direction, the profile easily along the protuberance abutted is planar distortion and easily slides.

In addition, bag portion 22 is preferably made up of the low temperature at negative less than 20 DEG C also soft material that is non-sclerous, that can not fix with deformed shape.Therefore, in the present embodiment, fitting portion 21 is made up of rigid plastics, and bag portion 22 is formed by negative 60 DEG C of also non-sclerous flexible plastics.In addition, be supposed to abut and reliably airtight bag portion 22 with the protuberance of the reveal being arranged on drawer type, preferably along press-in protuberance shape deformation and abut with planar.Or, abut with multiple wire thus abut in planar.

Such as, as shown in Figure 3, form the auxiliary pad 20 of following structure, it has: fitting portion 21, has thick wall thickness (thickness of slab) and section is U-shaped; Bag portion 22, it is set to hang down in the below of fitting portion 21, and section is breaded fish stick shape, bag portion 22 has and forms arcuation contact site 22a protuberance and par 22b, this arcuation contact site 22a below by planarized for the back part of protuberance before this rear formation are thin wall thickness (thickness) and easily along the shape deformation of the protuberance of abutting above.

Although the auxiliary pad of said structure 20 is for having the structure in the fitting portion 21 and bag portion 22 be made up of flexible plastic be made up of rigid plastics, by section shape is constant, thus can be easily shaped integral production by resin extruded.In addition, if the integrally formed product being shaped by resin extruded and being formed, then can easily tackle thicken fitting portion 21 thickness of slab to improve the demand of installation strength, and easily arcuation contact site 22a and the thickness of par 22b are below formed as the demand of the minimal thickness specified by reply.

As shown in Figure 4, bag portion 22 is disposed of and hangs down downwards when being fitted together to and being assemblied in installation portion 71 by fitting portion 21.If the door 4Aa of pushing drawer type makes it to close, then the arcuation contact site 22a in the bag portion 22 of this state that hangs down is made to be connected to protuberance 42.Because arcuation contact site 22a is by easily to slide and the flexible plastic holding yielding material and thickness is formed, therefore when abutting with protuberance 42, arcuation abutting part 22a is easily along the shape deformation of protuberance 42.

The door 4Aa of drawer type has: the bearing surface 41 of frame-shaped, and it is the tabular surface arranging door gasket 30, opposed with the surrounding front surface in refrigerating chamber front openings portion; Protuberance 42, it is arranged at least 1 limit of the inner circumferential side of the bearing surface 41 of this frame-shaped, and in the case of refrigerator, direction is outstanding.

Therefore, with the operations linkage of the door 4Aa of closedown drawer type, door gasket 30 is close to airtight for the complete cycle of opening portion with the body openings portion of refrigerator.Now, abut before the protuberance 42 that the arcuation contact site 22a be made up of flexible plastic and the inner circumferential side of door gasket 30 of the inner surface being arranged at a 4Aa at complete cycle configure and be extruded as planar, thus be reliably close to the whole region of long side direction before the protuberance 42 of reveal, suppress spilling of cold air.

That is, if close door 4Aa, then door gasket 30 is close to airtight for the complete cycle of opening portion with the body openings portion of refrigerator, and the arcuation contact site 22a be made up of flexible plastic of auxiliary pad 20 with abut before the protuberance 42 of reveal and be extruded as planar.Thus, be reliably close in planar with the whole region of the long side direction of the protuberance 42 of reveal, can reliably suppress cold air to spill to door gasket 30 direction.

Protuberance 42 can be the protuberance of the linearity longer than the width of storage case 43.In addition, also can be the protuberance of frame-shaped surrounding storage case 43.No matter which kind of situation, as long as bag-shaped auxiliary pad 20 is linearly be arranged on being equivalent on 1 limit of front upper of storage case 43.That is, the door 4Aa of drawer type preferably has: the bearing surface of frame-shaped, and it is the tabular surface arranging door gasket 30, and opposed with the surrounding front surface in refrigerating chamber front openings portion; Protuberance 42, it is arranged at least 1 limit of the inner circumferential side of the bearing surface of this frame-shaped, and outstanding to direction in the case of refrigerator.

In addition, bag-shaped auxiliary pad 20 can be made to be connected to protuberance 42 in planar, and described protuberance 42 is positioned at the front upper of storage case 43 and length is longer than the width of storage case 43, thus closes door 4Aa.Thus, inhibit the cold air being supplied to storage case 43 to flow out in door gasket 30 side, achieve efficient cold air flow, can energy-saving effect be played.

Namely, according to the present embodiment, as shown in the dotted line in figure and × mark, the cold air flow R2 towards door gasket 30 side is stopped well, as shown in the solid line in figure and circle, generate the periphery circulation along storage case 43 and the cold air flow R1 circulated in the freezing interior space 44.Thereby, it is possible to effectively suppress the cold air delivering to refrigerating chamber 4 to flow out from storage case 43 to door gasket 30 side, the cold air delivering to refrigerating chamber 4 can be reliably suppressed externally to spill generation heat leak.

Next, as the embodiment shape of fitting portion 21 and bag portion 22 being carried out to various change, to from the auxiliary pad 20 (embodiment 1) of the 1st example, each embodiment of the auxiliary pad 20D (embodiment 5) of auxiliary pad 20A (embodiment 2) ~ the 5th example of the 2nd example illustrates as follows.

< embodiment 1 >

Embodiment 1 is the auxiliary pad 20 shown in Fig. 3, has: be formed as section コ shape and have the fitting portion 21 of pinning portion 21a, have the bag portion 22 of arcuation contact site 22a and the section breaded fish stick type of par 22b below.

Fitting portion 21 is made up of the rigid plastics of thickness about 1mm above (such as, 1 ~ 2mm), and bag portion 22 is made up of the flexible plastic of below thickness 1mm (such as, 0.4 ~ 0.6mm).In addition, as mentioned above, be shaped integrally formed for the auxiliary pad 20 in the bag portion 22 with the fitting portion 21 be made up of rigid plastics and the section breaded fish stick type be made up of flexible plastic by resin extruded.

Therefore, it is possible to the auxiliary pad 20 by using the mould of regulation shape easily to manufacture the section breaded fish stick type with arcuation contact site 22a.In addition, easily can tackle thinning arcuation contact site 22a and make it to hold yielding demand, can also easily tackle thicken par 22b below wall thickness to improve the demand of strength of parts.

In the present embodiment, the thickness of arcuation contact site 22a and the thickness of par 22b are below formed as the lower thickness of equal extent.This is because the thickness identical when both are made up of identical soft plastic material is more convenient for being shaped.In addition, as described later, also can be the type of the thickness thickening par 22b below.

For making arcuation contact site 22a abut rear easy distortion with protuberance 42, arcuation contact site is formed as the section breaded fish stick type that forwards side is outstanding, this arcuation contact site 22a abuts with protuberance 42, and then is planar distortion along the outer shape of protuberance 42.That is, the outer shape along protuberance 42 is that planar abuts distortion, thus reliably stops towards the cold air flow R2 of door gasket side.

When pushing the door 4Aa closing drawer type, the front face side being connected to the bag portion 22 of protuberance 42 is formed as reliably abutting and holds yielding arcuation contact site 22a, and can be smooth without the need to the side below of distortion.In addition, if side is par 22b below below, then easily can tackles and the requirement that support carries out supporting is set at main body side, therefore comparatively preferred.

As long as the arcuation contact site 22a that bag portion 22 meets front face side abuts with protuberance 42 and the condition of being easily out of shape in planar, also can be the shape beyond section breaded fish stick type.In addition, the structure of installation portion also can carry out various change, and the example therefore for the structure of the example and change installation portion that the section shape in bag portion 22 are formed as the shape beyond section breaded fish stick type illustrates as follows.

< embodiment 2 >

Then, the auxiliary pad 20A of Fig. 5 to embodiment 2 is used to be described.Auxiliary pad 20A is identical with the auxiliary pad 20 of embodiment 1, has fitting portion 21 that engage with the installation portion 71 of the main body side being arranged on refrigerator 1, section コ shape.But difference is, bag portion is not section breaded fish stick type, but forms the bag portion 22A of overall outstanding section tear type.

Therefore, mainly different to this bag portion 22A is described.Both something in common are that bag portion 22A has the arcuation contact site 22Aa that forwardly side is outstanding.But, side non-flat forms after but slightly toward rear outstanding, 22A entirety in bag portion is formed as section tear type.Even such shape, the arcuation contact site 22Aa also meeting front face side abuts with protuberance 42 and is the condition that planar is out of shape.

This bag of portion 22A is also made up of the flexible plastic of below thickness 1mm (such as, 0.4 ~ 0.6mm).In addition, something in common is also, is shaped integrally formed by having the fitting portion 21 be made up of rigid plastics with the auxiliary pad 20A of the bag portion 22A of the section tear type be made up of flexible plastic by resin extruded.

That is, by using the mould of regulation shape, the auxiliary pad 20A of section tear type can easily be manufactured.Even the auxiliary pad 20A of section tear type, form arcuation contact site 22Aa by protuberance above too, and abut with the protuberance 42 being arranged on reveal, and can be planar distortion along the outer shape of protuberance 42.

Therefore, even have the auxiliary pad 20A of the bag portion 22A of section tear type, also can abut along the outer shape of protuberance 42 and be planar distortion, reliably stop towards the cold air flow R2 of door gasket side.

< embodiment 3 >

Then, the auxiliary pad 20B of Fig. 6 to embodiment 3 is used to be described.Auxiliary pad 20B is different from the auxiliary pad 20 of embodiment 1, has fitting portion 21A, and this fitting portion 21A engages with installation portion 71A, the installation sheet of the installation portion that described installation portion 71A has a main body side being arranged on refrigerator 1 lateral bend backward.In addition, difference part is, bag portion neither section breaded fish stick type neither tear type, but forms the bag portion 22B of section ellipse longitudinally partially long on the whole.

Bag portion 22B is the shape of drawing elongated further by the bag portion 22A of aforesaid section tear type, and be compare oppressed fore-and-aft direction, the section shape of lengthwise that above-below direction is grown partially.According to this structure, even if there is deviation at above-below direction because of the aging door of drawer type that causes of refrigerator 1, by being used in the auxiliary pad 20 that above-below direction is grown partially, also can the cold air of reliably freezing-inhibiting indoor flow out to door gasket side.

Even the bag portion 22B of section ellipse, something in common is still formation front face side and abuts with protuberance 42 and the arcuation contact site 22Ba be out of shape in planar.Though fitting portion 21A and aforesaid fitting portion 21 are all section コ shape, but it is towards difference, are shape that can be chimeric with installation portion 71A bending backwards, by fitting portion 21A is installed on installation portion 71A, bag portion 22B are supported along vertical.The thickness of this fitting portion 21A can be about 1mm above (such as, 1 ~ 2mm), and bag portion 22B can be below thickness 1mm (such as, 0.4 ~ 0.6mm).In addition, the auxiliary pad 20B of this structure also can be shaped integrally formed by resin extruded.

That is, by using the mould of regulation shape, the auxiliary pad 20B of section ellipse can easily be manufactured.Even if this structure, also can be formed in when protuberance abuts with protuberance 42 above, easily along the arcuation contact site 22Ba that the outer shape of protuberance 42 is out of shape.

Therefore, even have the auxiliary pad 20B of the bag portion 22B of section ellipse, arcuation contact site 22Ba also can abut with protuberance 42 and outer shape along protuberance 42 is that planar is out of shape, and can reliably stop towards the cold air flow R2 of door gasket side.

< embodiment 4 >

Then, the auxiliary pad 20C of Fig. 7 to embodiment 4 is used to be described.Auxiliary pad 20C is different from the auxiliary pad 20 of embodiment 1, there is fitting portion 21B, this fitting portion 21B has shape that can be chimeric with the lower edge entirety of installation portion 71B, the L-type section of this installation portion 71B to be the installation portion of the main body side being arranged on refrigerator 1 be lateral bend forward, but there is short lower edge.In addition, difference part is, though bag portion is breaded fish stick type profile, but is the bag portion 22C of the thickness having thickened par 22Cb below.

Though fitting portion 21B and aforesaid fitting portion 21 are all コ shape section, so but difference part to engage in the mode clamping the lower edge of installation portion 71B by the upper edge 21Ba of コ shape section and lower edge 21Bb.That is, not only make fitting portion 21B chimeric with installation portion 71B, the whole lower edge also clamping installation portion 71B is installed, and is supported by bag portion 22B thus along vertical.The thickness of this fitting portion 21B can be that about 1mm is above (such as equally, 1 ~ 2mm), about the thickness of bag portion 22C, before it, the thickness of the arcuation contact site 22Ca of protuberance is preferably below 1mm (such as, 0.4 ~ 0.6mm), the thickness of par 22Cb can thicker (such as, 0.8 ~ 2mm) below.In addition, the auxiliary pad 20C of this structure also can be shaped integrally formed by resin extruded.

That is, by using the mould of regulation shape, the auxiliary pad 20C of breaded fish stick type profile can easily be manufactured.According to this structure, can be formed when protuberance abuts with protuberance 42 above, easily along the arcuation contact site 22Ca that the outer shape of protuberance 42 is out of shape.

Therefore, adopt breaded fish stick type profile and have thin arcuation contact site 22Ca with thick after the auxiliary pad 20C of bag portion 22C of par 22Cb, being more prone to along the outer shape of protuberance 42 is planar distortion, can reliably stop towards the cold air flow R2 of door gasket side.

< embodiment 5 >

Though it is comparatively preferred that the aforesaid inserted type of the installation method of auxiliary pad (pinning formula) is convenient to handling, also can be but other installation methods in addition, therefore as the variation of this installation method, Fig. 8 is utilized to be described as embodiment 5 fixing for rivet embodiment.

The difference of the auxiliary pad 20D shown in Fig. 8 is that the fitting portion 21 by the auxiliary pad 20 of embodiment 1 is formed as the fitting portion 21C of rivet fixed.That is, the installation portion 71 of inserted type is not set in refrigerator main body side, and the installation portion 72 of rivet fixed is set, make the fitting portion 21C of auxiliary pad 20D chimeric with this installation portion 72, and use rivet 73 to be fixed.

Rivet 73 can be fixed for screw thread, also can use pluggable pin parts, be formed auxiliary pad 20D in the mode that can load and unload.Even if this mounting structure, also by fitting portion 21C is installed on installation portion 72, bag portion 22 is supported along vertical.The thickness of this fitting portion 21C can be that about 1mm is above (such as, 1 ~ 2mm), about the thickness in bag portion 22, preferably before it thickness of the arcuation contact site 22Ca of protuberance be below 1mm (such as, 0.4 ~ 0.6mm), the thickness of par 22Cb can be thinner below, also can be thicker.In addition, the auxiliary pad 20D of this structure also can be shaped integrally formed by resin extruded.

That is, by using the mould of regulation shape, the auxiliary pad 20D of breaded fish stick type profile can easily be manufactured.Even if such structure, also can be formed when protuberance abuts with protuberance 42 above, easily along the arcuation contact site 22Ca that the outer shape of protuberance 42 is out of shape.

Therefore, even have the auxiliary pad 20D of the fitting portion 21C of rivet fixed and the bag portion 22C of breaded fish stick type profile, before bag portion 22C, protuberance (arcuation contact site 22Ca) also can abut with protuberance 42, and be planar distortion along the outer shape of protuberance 42, can reliably stop towards the cold air flow R2 of door gasket side.

As mentioned above, embodiment 1 ~ the embodiment 5 of auxiliary pad 20,20A ~ 20D is illustrated, in above-mentioned any embodiment, all by making the protuberance 42 arranged in the inner side of the door 4Aa of drawer type abut with the arcuation contact site 22a in the bag portion 22 of auxiliary pad, and the arcuation contact site 22a be made up of flexible plastic is planar distortion along the outer shape of protuberance 42, stops cold air path.

Therefore, below utilize that Fig. 9, Figure 10 are different to the outer shape because of protuberance 42, arcuation contact site 22a abuts deformation condition and how to change and be described.Fig. 9 is the brief description figure that the 1st of expression auxiliary pad makes use-case, represents that arcuation contact site 22a abuts the state of being out of shape with the protuberance 42A in the bight with C chamfering shape.Figure 10 is the brief description figure that the 2nd of expression auxiliary pad makes use-case, represents that arcuation contact site 22a abuts the state of being out of shape with the protuberance 42B of the fillet with R rounding shape.

Parts are in most cases all by bight chamfering.Such as, by implement oblique line cutting C chamfering or as fillet the R rounding of chamfering, avoid when people's contact or holding injured.Therefore, auxiliary pad 20 being abutted the appearance of being out of shape with the bight of C chamfering shape as embodiment 6 utilizes Fig. 9 to be described, and auxiliary pad 20 is abutted the appearance of being out of shape with the bight of R rounding shape as embodiment 7 to utilize Figure 10 to be described.

< embodiment 6 >
