第2圖係自側面觀看本發明實施形態1之冰箱1所得之剖面圖。如第2圖所示，冰箱1係包括由形成有儲藏室之內箱51、及位於內箱51之外側，形成外框之外箱52所構成之箱體50。在冰箱1的內部的內箱51與外箱52之間，也設有冷卻機17、壓縮機19及送風扇18。Fig. 2 is a cross-sectional view of the refrigerator 1 according to Embodiment 1 of the present invention viewed from the side. As shown in FIG. 2, the refrigerator 1 includes a cabinet 50 composed of an inner box 51 in which a storage compartment is formed, and an outer box 52 located outside the inner box 51 and forming an outer frame. Between the inner box 51 and the outer box 52 inside the refrigerator 1, a cooler 17, a compressor 19, and a blower fan 18 are also provided.

在外箱52固定有第一真空絕熱材54，在內箱51固定有第二真空絕熱材55。在內箱51與外箱52之間，填充有聚氨酯發泡體16，藉第一真空絕熱材54、第二真空絕熱材55及聚氨酯發泡體16，抑制熱進入各儲藏室。聚氨酯發泡體16也可以係例如硬質聚氨酯發泡體。The first vacuum insulation material 54 is fixed to the outer box 52, and the second vacuum insulation material 55 is fixed to the inner box 51. Between the inner box 51 and the outer box 52, the polyurethane foam 16 is filled, and the first vacuum insulation material 54, the second vacuum insulation material 55, and the polyurethane foam 16 are used to suppress heat from entering each storage room. The polyurethane foam 16 may be a rigid polyurethane foam, for example.

冷卻機17係生成冷卻各儲藏室之冷氣。在鄰接於冷凍室500之內箱51與外箱52之間，形成有機械室24，其收容有壓縮機19。冷卻機17係被配置於配置有壓縮機19之機械室24上方，被壓縮機19運轉而生成冷氣。由冷卻機17所生成之冷氣，係藉送風扇18，被送入各儲藏室。各儲藏室之溫度，係由被設於各儲藏室內部之未圖示熱敏電阻所檢出，藉調整未圖示之阻尼器之開度、壓縮機19之輸出、及送風扇18之送風量以控制，使得成為事先設定之溫度。在各儲藏室中，也設有用於分隔收納空間之食品架20及食品收納盒21等。The cooler 17 generates cold air for cooling each storage room. Between the inner box 51 and the outer box 52 adjacent to the freezer compartment 500, a machine room 24 is formed, which houses the compressor 19. The cooler 17 is arranged above the machine room 24 where the compressor 19 is arranged, and is operated by the compressor 19 to generate cold air. The cold air generated by the cooler 17 is sent to each storage room by the blower fan 18. The temperature of each storage room is detected by a thermistor (not shown) provided inside each storage room, by adjusting the opening of the damper (not shown), the output of the compressor 19, and the delivery of the fan 18 The air volume is controlled so that it becomes a preset temperature. In each storage room, a food rack 20, a food storage box 21, and the like for partitioning the storage space are also provided.

在冷卻機17與壓縮機19之間，設有除霜加熱器22、除霜配管53及排水盤23。除霜加熱器22係被設於冷卻機17之下部，融化附著在冷卻機17上之霜。除霜配管53係用於通過除霜水者，其係自冷卻機17下部通到機械室24之配管。排水盤23係儲存除霜水者，其位於除霜配管53之下部，被配置於壓縮機19的上表面等。除霜配管53也可以被設成連接冷卻機17與排水盤23。Between the cooler 17 and the compressor 19, a defrost heater 22, a defrost piping 53 and a drain pan 23 are provided. The defrost heater 22 is provided below the cooler 17, and melts the frost adhering to the cooler 17. The defrosting piping 53 is for passing through the defrosting water, and is a piping leading from the lower part of the cooler 17 to the machine room 24. The drain pan 23 is for storing defrosted water, is located under the defrosting piping 53, and is arranged on the upper surface of the compressor 19 or the like. The defrosting piping 53 may be provided to connect the cooler 17 and the drain pan 23.

被配置於外箱52之第一真空絕熱材54，係呈平面形狀，覆蓋冷藏室100、切換室200、製冰室300及蔬果室400的背面。第一真空絕熱材54係不被配置於外箱52與鄰接冷凍室500之機械室24之間。第一真空絕熱材54係藉黏著劑等，接著在外箱52。The first vacuum insulation material 54 disposed in the outer box 52 has a planar shape and covers the back of the refrigerator compartment 100, the switching compartment 200, the ice making compartment 300, and the vegetable and fruit compartment 400. The first vacuum insulation material 54 is not arranged between the outer box 52 and the machine room 24 adjacent to the freezing room 500. The first vacuum insulation material 54 is adhered to the outer box 52 by an adhesive or the like.

被配置於內箱51之第二真空絕熱材55，係位於冷凍室500與除霜配管53及機械室24之間。第二真空絕熱材55係尺寸小於第一真空絕熱材54，局部形成為彎曲形狀，使得沿著內箱51之形狀配置。在此，所謂第一真空絕熱材54或第二真空絕熱材55之尺寸，係指第二真空絕熱材55被彎曲前之狀態中之上下方向、左右方向及厚度方向之長度，或者，表面積。第二真空絕熱材55係藉黏著劑等，接著在未干涉除霜配管53及機械室24等之周邊零件之內箱51上。The second vacuum insulation material 55 arranged in the inner box 51 is located between the freezing room 500 and the defrosting piping 53 and the machine room 24. The second vacuum insulation material 55 is smaller in size than the first vacuum insulation material 54 and is partially formed in a curved shape so as to be arranged along the shape of the inner box 51. Here, the size of the first vacuum insulation material 54 or the second vacuum insulation material 55 refers to the length in the up-down direction, the left-right direction and the thickness direction, or the surface area in the state before the second vacuum insulation material 55 is bent. The second vacuum heat insulating material 55 is adhered to the inner box 51 of peripheral parts such as the non-interference defrosting piping 53 and the machine room 24 by means of an adhesive or the like.

冰箱1之動作中，當冷卻機17周圍變成低溫時，有時冷卻機17會附著霜。附著在冷卻機17上之霜，係藉除霜加熱器22而融化成為除霜水。除霜水係通過位於冷卻機17與排水盤23間之除霜配管53，儲存在被配置於壓縮機19上表面上之排水盤23。而且，除霜水係藉壓縮機19之熱而蒸發，自被設於機械室24之排出口25被排出。During the operation of the refrigerator 1, when the temperature around the cooler 17 becomes low, frost may adhere to the cooler 17 in some cases. The frost adhering to the cooler 17 is melted by the defrost heater 22 into defrost water. The defrosting water is stored in the drain pan 23 arranged on the upper surface of the compressor 19 through the defrost piping 53 between the cooler 17 and the drain pan 23. In addition, the defrosted water is evaporated by the heat of the compressor 19 and discharged from the discharge port 25 provided in the machine room 24.

通過有除霜水之除霜配管53，係藉被設於與內箱51之間之第二真空絕熱材55，與低溫之冷凍室500絕熱。因此，可抑制除霜水因為冷凍室500溫度之影響而冷卻，同時也可以抑制熱自壓縮機19及外部大氣進入冷凍室500。The defrosting piping 53 with defrosting water is insulated from the freezing chamber 500 at a low temperature by the second vacuum insulation material 55 provided between the inner box 51 and the second vacuum insulation material 55. Therefore, it is possible to suppress the defrosting water from being cooled due to the influence of the temperature of the freezing compartment 500, and it is also possible to suppress the heat from entering the freezing compartment 500 from the compressor 19 and the outside atmosphere.

第一真空絕熱材54係不設於除霜配管53及機械室24與外箱52之間，所以，除霜配管53及機械室24與外部大氣間之絕熱性變低。因此，使被配置於機械室24之壓縮機19之熱，釋出到冰箱1外，同時變得較容易提高熱自外部大氣往除霜配管53流入之情事。The first vacuum insulation material 54 is not provided between the defrosting piping 53 and the machine room 24 and the outer box 52, so the heat insulation between the defrosting piping 53 and the machine room 24 and the outside atmosphere becomes low. Therefore, the heat of the compressor 19 disposed in the machine room 24 is released to the outside of the refrigerator 1, and at the same time, it becomes easier to increase the inflow of heat from the outside atmosphere to the defrosting piping 53.

第一真空絕熱材54係尺寸較大且呈平面形狀，所以，固定比較容易，接著面較廣，所以，可維持接著力。第二真空絕熱材55係尺寸小於第一真空絕熱材54，所以，重量也較小，即使第二真空絕熱材55與內箱51之接觸面積不會比較大時，也可以防止因為老化等所致之剝離。The first vacuum insulation material 54 has a large size and a flat shape, so it is easier to fix and the bonding surface is wider, so the bonding force can be maintained. The size of the second vacuum insulation material 55 is smaller than that of the first vacuum insulation material 54, so the weight is small, even if the contact area between the second vacuum insulation material 55 and the inner box 51 is not relatively large, it can be prevented Cause stripping.

以上說明過之實施形態1之冰箱1係包括：第一真空絕熱材54，被固定於外箱52；以及第二真空絕熱材55，被配置於內箱51與除霜配管53之間，尺寸小於第一真空絕熱材54。因此，可使第一真空絕熱材54及第二真空絕熱材55之接著更確實。又，熱自外部大氣往各儲藏室流入之情事係被抑制。而且，第一真空絕熱材54係不被設於除霜配管53及機械室24與外箱52之間，所以，可使產生自壓縮機19之熱，效率良好地往冰箱1外釋出，自外部大氣往除霜配管53流入之熱係提高，可抑制除霜水之凍結。The refrigerator 1 of the first embodiment described above includes: the first vacuum insulation material 54 fixed to the outer box 52; and the second vacuum insulation material 55 arranged between the inner box 51 and the defrosting piping 53 in size Less than the first vacuum insulation 54. Therefore, the bonding of the first vacuum insulation material 54 and the second vacuum insulation material 55 can be made more reliable. In addition, the fact that heat flows into the storage rooms from the outside atmosphere is suppressed. In addition, the first vacuum insulation material 54 is not provided between the defrosting piping 53 and the machine room 24 and the outer box 52. Therefore, the heat generated from the compressor 19 can be efficiently released outside the refrigerator 1, The heat flow from the outside atmosphere to the defrost piping 53 is increased, and the freezing of the defrost water can be suppressed.

又，第二真空絕熱材55係位於內箱51與除霜配管53之間，所以，可抑制流動在除霜配管53之除霜水，因為冷凍室500溫度之影響而被冷卻凍結。In addition, since the second vacuum insulation material 55 is located between the inner box 51 and the defrosting piping 53, the defrosting water flowing through the defrosting piping 53 can be suppressed from being cooled and frozen due to the influence of the temperature of the freezing chamber 500.

又，第二真空絕熱材55係位於內箱51與配置有壓縮機19之機械室24之間，所以，自壓縮機19及外部大氣流入冷凍室500之熱係被抑制，可抑制冰箱1之消耗電力。In addition, the second vacuum insulation material 55 is located between the inner box 51 and the machine room 24 in which the compressor 19 is arranged. Therefore, the heat system flowing into the freezer compartment 500 from the compressor 19 and the outside air is suppressed, and the refrigerator 1 can be suppressed. Power consumption.

又，使小於第一真空絕熱材54之第二真空絕熱材55，成為沿著機械室24之形狀之彎曲形狀，藉此，可增加與不干涉到除霜配管53或機械室24等之周邊零件之內箱51之接觸面。因此，可提高第二真空絕熱材55與內箱51之接著力，可防止由劣化等所致之第二真空絕熱材55之剝離。又，第二真空絕熱材55可不分割成複數個，所以，可提高覆蓋率，提高絕熱性，同時也可抑制作業性之惡化。In addition, the second vacuum insulation material 55 smaller than the first vacuum insulation material 54 is formed into a curved shape along the shape of the machine room 24, whereby the periphery of the defrost piping 53, the machine room 24, etc. can be increased or not interfered The contact surface of the inner box 51 of the parts. Therefore, the adhesive force between the second vacuum insulation material 55 and the inner box 51 can be increased, and the peeling of the second vacuum insulation material 55 due to deterioration or the like can be prevented. In addition, the second vacuum heat insulating material 55 need not be divided into a plurality of parts. Therefore, the coverage rate can be improved, the heat insulating property can be improved, and the deterioration of workability can also be suppressed.

又，第一真空絕熱材54不僅不位於外箱52與壓縮機19之間，也不位於外箱52與除霜配管53之間。因此，產生自壓縮機19之熱係效率良好地往冰箱1外釋出，可抑制冰箱1之消耗電力。In addition, the first vacuum insulation material 54 is not located not only between the outer case 52 and the compressor 19 but also between the outer case 52 and the defrosting piping 53. Therefore, the heat generated from the compressor 19 is efficiently released outside the refrigerator 1, and the power consumption of the refrigerator 1 can be suppressed.

實施形態2. 第3圖係自側面觀看本發明實施形態2之冰箱1所得之剖面圖。基本構造係與實施形態1相同，但是，關於除霜配管53及第一真空絕熱材54之構造係與實施形態1不同。Embodiment 2. Fig. 3 is a cross-sectional view of the refrigerator 1 according to Embodiment 2 of the present invention viewed from the side. The basic structure is the same as the first embodiment, but the structure of the defrosting piping 53 and the first vacuum insulation material 54 is different from the first embodiment.

如第3圖所示，實施形態2之冰箱1的除霜配管53，係在內面包括對應冰箱1之運轉狀態或周邊之環境而通電之除霜配管用加熱器56。除霜配管用加熱器56最好係被固定於除霜配管53上。As shown in FIG. 3, the defrosting piping 53 of the refrigerator 1 of the second embodiment includes a heater 56 for defrosting piping which is energized in accordance with the operating state of the refrigerator 1 or the surrounding environment. The heater 56 for defrosting piping is preferably fixed to the defrosting piping 53.

第一真空絕熱材54係覆蓋冷藏室100、切換室200、製冰室300及蔬果室400的背面，同時被固定於外箱52，使得至除霜配管53與外箱52之間為止。但是，第一真空絕熱材54係不覆蓋具有壓縮機19之機械室24。The first vacuum insulation material 54 covers the rear surfaces of the refrigerator compartment 100, the switching compartment 200, the ice making compartment 300, and the vegetable and fruit compartment 400, and is also fixed to the outer box 52 so as to be between the defrosting piping 53 and the outer box 52. However, the first vacuum insulation material 54 does not cover the machine room 24 having the compressor 19.

附著在冷卻機17之霜，係被除霜加熱器22融化而成為除霜水，以到達除霜配管53，一邊熱自被設於除霜配管53之除霜配管用加熱器56流入，一邊通過除霜配管53而儲存在排水盤23。而且，除霜水係藉壓縮機19之熱而蒸發，被排出到外部。The frost adhering to the cooler 17 is melted by the defrost heater 22 to become defrosting water to reach the defrosting piping 53 while the heat flows in from the defrosting piping heater 56 provided in the defrosting piping 53. It is stored in the drain pan 23 through the defrosting piping 53. Moreover, the defrosted water is evaporated by the heat of the compressor 19 and is discharged to the outside.

藉設置除霜配管用加熱器56，提高熱流入除霜配管53。藉此，即使藉來自各儲藏庫之冷氣，而除霜配管53變成低溫時，藉除霜配管53，可抑制除霜水冷卻以凍結。By providing the heater 56 for the defrosting piping, the heat flow into the defrosting piping 53 is increased. With this, even if the defrosting piping 53 becomes low temperature by the cold air from each storage, the defrosting piping 53 can suppress the cooling of the defrosting water to freeze.

又，在除霜配管53與外箱52之間，配置有第一真空絕熱材54，除霜配管53與外部大氣係被絕熱。因此，除霜配管用加熱器56之熱係效率良好地流入除霜水，可抑制往外部大氣之散熱。In addition, a first vacuum insulation material 54 is arranged between the defrosting piping 53 and the outer box 52, and the defrosting piping 53 is insulated from the outside air system. Therefore, the heat system of the heater 56 for defrosting piping flows into the defrosting water efficiently, and heat radiation to the outside atmosphere can be suppressed.

以上說明過之實施形態2之冰箱1，係包括被固定於除霜配管53之除霜配管用加熱器56，第一真空絕熱材54係位於除霜配管53與外箱52之間。藉此，自除霜配管用加熱器56往外部大氣之散熱係被抑制，熱效率良好地流入除霜配管53的除霜水，所以，可抑制消耗電力。The refrigerator 1 of the second embodiment described above includes the heater 56 for the defrosting piping fixed to the defrosting piping 53, and the first vacuum insulation material 54 is located between the defrosting piping 53 and the outer box 52. As a result, the heat dissipation system from the heater 56 for defrosting piping to the outside atmosphere is suppressed, and the defrosting water that flows into the defrosting piping 53 with good thermal efficiency can suppress power consumption.

又，第一真空絕熱材54係不位於外箱52與壓縮機19之間，藉此，可使產生自壓縮機19之熱，效率良好地往冰箱1外釋出，所以，可抑制冰箱1之消耗電力。In addition, the first vacuum insulation material 54 is not located between the outer case 52 and the compressor 19, whereby the heat generated from the compressor 19 can be efficiently released outside the refrigerator 1, so the refrigerator 1 can be suppressed Power consumption.

實施形態3. 第4圖係自側面觀看本發明實施形態3之冰箱1的冷凍室500周邊所得之剖面圖。基本構造係與實施形態1相同，但是，第二真空絕熱材55之形狀係與實施形態1不同。Embodiment 3. FIG. 4 is a cross-sectional view of the freezer compartment 500 of the refrigerator 1 according to Embodiment 3 of the present invention viewed from the side. The basic structure is the same as the first embodiment, but the shape of the second vacuum insulation material 55 is different from the first embodiment.

如第4圖所示，本發明實施形態3之冰箱1，係在第二真空絕熱材55形成有第一凹狀55a與第二凹狀55b。As shown in FIG. 4, in the refrigerator 1 according to Embodiment 3 of the present invention, the first concave 55a and the second concave 55b are formed in the second vacuum insulation material 55.

第二真空絕熱材55的第一凹狀55a，係被形成於與內箱51之接觸面上。在配置有第二真空絕熱材55之內箱51，形成有凸狀51a，凸狀51a與第一凹狀55a係相卡合，在內箱51固定有第二真空絕熱材55。The first concave 55 a of the second vacuum insulation material 55 is formed on the contact surface with the inner box 51. A convex 51a is formed in the inner box 51 where the second vacuum heat insulating material 55 is arranged. The convex 51a is engaged with the first concave 55a. The second vacuum heat insulating material 55 is fixed to the inner box 51.

第二真空絕熱材55的第二凹狀55b，係被形成於與內箱51之接觸面的相反面。第二凹狀55b係被設於內箱51與機械室24相接近之處所。而且，第一凹狀55a與第二凹狀55b係被設成分離，使得在投影面上不重疊。The second concave 55b of the second vacuum insulation material 55 is formed on the surface opposite to the contact surface with the inner box 51. The second concave 55b is provided near the inner box 51 and the machine room 24. Moreover, the first concave shape 55a and the second concave shape 55b are provided so as not to overlap on the projection surface.

第二真空絕熱材55係沿著形成有凸狀51a之內箱51配置。而且，第二真空絕熱材55的第一凹狀55a與被形成於內箱51之凸狀51a係相卡合，而第二真空絕熱材55被定位。而且，在該狀態下，第二真空絕熱材55與內箱51係藉黏著劑等，被接著固定。The second vacuum insulation material 55 is arranged along the inner box 51 in which the convex shape 51a is formed. Furthermore, the first concave shape 55a of the second vacuum insulation material 55 is engaged with the convex shape 51a formed in the inner box 51, and the second vacuum insulation material 55 is positioned. Further, in this state, the second vacuum insulation material 55 and the inner box 51 are fixed by adhesive or the like.

被固定於內箱51之第二真空絕熱材55，係與內箱51之接觸面的相反面，被聚氨酯發泡體16覆蓋。被設於第二真空絕熱材55之第二凹狀55b，係成為聚氨酯發泡體16的流路，而提高流動性，所以，聚氨酯發泡體16係被均勻填充。The second vacuum insulation material 55 fixed to the inner box 51 is opposite to the contact surface with the inner box 51 and is covered with the polyurethane foam 16. The second concave 55b provided in the second vacuum heat insulating material 55 serves as a flow path of the polyurethane foam 16 and improves fluidity. Therefore, the polyurethane foam 16 is uniformly filled.

而且，在實施形態3之第一凹狀55a及第二凹狀55b之構造中，也可以係組合實施形態2的除霜配管用加熱器56之構造。In addition, in the structure of the first concave shape 55a and the second concave shape 55b of the third embodiment, the structure of the heater 56 for the defrosting piping of the second embodiment may be combined.

以上說明過之實施形態3之冰箱1，係第二真空絕熱材55在與內箱51之接觸面，具有第一凹狀55a。因此，可增大第二真空絕熱材55與內箱51之接觸面。又，可將第一凹狀55a當作對於內箱51之第二真空絕熱材55之固定位置之基準，所以，接著作業時之定位變容易，同時可如同計畫尺寸地，精度良好地設置第二真空絕熱材55。The refrigerator 1 of the third embodiment described above has the second vacuum insulation material 55 having a first concave shape 55a on the contact surface with the inner box 51. Therefore, the contact surface between the second vacuum insulation material 55 and the inner box 51 can be increased. In addition, the first concave shape 55a can be used as a reference for the fixed position of the second vacuum insulation material 55 of the inner box 51, so positioning during the work becomes easier, and at the same time, it can be set with high accuracy as planned dimensions Second vacuum insulation 55.

又，第二真空絕熱材55係在與內箱51之接觸面的相反面，具有第二凹狀55b。因此，在第二真空絕熱材55與機械室24接近之處所，可防止彼此干涉或極端接近，同時可充分確保聚氨酯發泡體16之流路。藉此，可提高聚氨酯發泡體16之流動性及填充性，可以減少機械室24對冷凍室500之熱影響，以抑制消耗電力。In addition, the second vacuum insulation material 55 is opposite to the contact surface with the inner box 51 and has a second concave shape 55b. Therefore, where the second vacuum insulation material 55 and the machine room 24 are close to each other, it is possible to prevent interference or extremely close to each other, and at the same time to sufficiently ensure the flow path of the polyurethane foam 16. As a result, the fluidity and filling properties of the polyurethane foam 16 can be improved, and the thermal influence of the machine room 24 on the freezing room 500 can be reduced to suppress power consumption.

又，第一凹狀55a與第二凹狀55b，係被形成於在投影面上不重疊之位置。因此，藉第二真空絕熱材55成為極端薄，可防止損害絕熱性，而且，可提高第二真空絕熱材55之安裝作業性或聚氨酯發泡體16之流動性及填充性。Moreover, the first concave shape 55a and the second concave shape 55b are formed at positions that do not overlap on the projection surface. Therefore, by making the second vacuum insulation material 55 extremely thin, the heat insulation property can be prevented from being impaired, and further, the installation workability of the second vacuum insulation material 55 or the fluidity and filling property of the polyurethane foam 16 can be improved.

又，被形成於內箱51之凸狀51a，係與被形成於與第二真空絕熱材55之接觸面上之第一凹狀55a相卡合，藉此，可更容易進行接著作業時之定位。In addition, the convex shape 51a formed in the inner box 51 is engaged with the first concave shape 55a formed on the contact surface with the second vacuum insulation material 55, thereby making it easier to perform work Positioning.

實施形態4. 第5圖係概略表示自側面觀看本發明實施形態4之冰箱1所得之剖面圖；第6圖係本發明實施形態4之冰箱1的除霜配管53周邊之放大圖。實施形態4係基本構造與實施形態1～3相同，但是，除霜配管53周邊之構造係與實施形態1～3不同。Embodiment 4. FIG. 5 is a schematic cross-sectional view of the refrigerator 1 according to Embodiment 4 of the present invention viewed from the side; FIG. 6 is an enlarged view of the periphery of the defrosting piping 53 of the refrigerator 1 according to Embodiment 4 of the present invention. The basic structure of the fourth embodiment is the same as the first to third embodiments, but the structure around the defrosting piping 53 is different from the first to third embodiments.

如第5圖及第6圖所示，本發明實施形態4之冰箱1，係在位於被設於外箱52之第一真空絕熱材54，與被設於內箱51之第二真空絕熱材55間之除霜配管53的外周側，包括除霜配管蓋體58。除霜配管蓋體58係具有圓筒形狀，在外周配置有除霜配管用加熱器56。除霜配管蓋體58及除霜配管用加熱器56，係位於第一真空絕熱材54與第二真空絕熱材55之間。除霜配管蓋體58及除霜配管用加熱器56，係被填充在除霜配管53與第一真空絕熱材54之間、及除霜配管53與第二真空絕熱材55間之聚氨酯發泡體16所包圍。As shown in FIGS. 5 and 6, the refrigerator 1 according to Embodiment 4 of the present invention is located between the first vacuum insulation material 54 provided in the outer box 52 and the second vacuum insulation material provided in the inner box 51 The outer peripheral side of the defrosting piping 53 between 55 includes a defrosting piping cover 58. The defrost piping cover 58 has a cylindrical shape, and a heater 56 for defrosting piping is arranged on the outer periphery. The defrost piping cover 58 and the defrost piping heater 56 are located between the first vacuum insulation material 54 and the second vacuum insulation material 55. The defrosting piping cover 58 and the defrosting piping heater 56 are filled with polyurethane foam between the defrosting piping 53 and the first vacuum insulation material 54 and between the defrosting piping 53 and the second vacuum insulation material 55 Surrounded by body 16.

除霜配管蓋體58係被配置成覆蓋除霜配管53，與位於除霜配管53之上部，在內部收容冷卻機17與除霜加熱器22之冷卻室57之接合處53a。又，除霜配管蓋體58係被配置成覆蓋除霜配管53，與位於除霜配管53下部之機械室24之接合處53b。The defrosting piping cover 58 is arranged to cover the defrosting piping 53 and the junction 53a which is located above the defrosting piping 53 and houses the cooling chamber 17 of the cooler 17 and the defrosting heater 22 inside. In addition, the defrosting pipe cover 58 is arranged to cover the defrosting pipe 53 and the junction 53b of the machine room 24 located below the defrosting pipe 53.

冷卻室57所產生之排水，係自冷卻室57下部通過除霜配管53，儲留在被配置於機械室24之排水盤23。此時，當於冷卻室57與除霜配管53之接合處53a，或者，除霜配管53與機械室24之接合處53b具有間隙時，有時排水自該間隙漏出。即使在這種情形下，接合處53a及接合處53b外側係被除霜配管蓋體58覆蓋，所以，排水不浸入聚氨酯發泡體16。The drain generated by the cooling chamber 57 passes through the defrosting piping 53 from the lower part of the cooling chamber 57 and is stored in the drain pan 23 arranged in the machine room 24. At this time, when there is a gap between the junction 53a of the cooling chamber 57 and the defrosting piping 53 or the joint 53b of the defrosting piping 53 and the machine chamber 24, drain water may leak from the gap. Even in this case, the outer sides of the joint 53a and the joint 53b are covered by the defrosting pipe cover 58, so that the drain does not infiltrate the polyurethane foam 16.

而且，在第6圖中，係圖示除霜配管蓋體58覆蓋除霜配管53與冷卻室57之接合處53a、及除霜配管53與機械室24之接合處53b之一構件。除霜配管蓋體58並不侷限於圖示之構造，除霜配管蓋體58例如也可以係由覆蓋除霜配管53與冷卻室57之接合處53a之構件、及覆蓋除霜配管53與機械室24之接合處53b之構件之二個構件所構成。In addition, in FIG. 6, the defrosting pipe cover 58 covers one of the joint 53 a of the defrosting pipe 53 and the cooling chamber 57 and the joint 53 b of the defrosting pipe 53 and the machine room 24. The defrosting pipe cover 58 is not limited to the structure shown in the figure, and the defrosting pipe cover 58 may be, for example, a member covering the junction 53a of the defrosting pipe 53 and the cooling chamber 57, and covering the defrosting pipe 53 and the machine The two members of the junction 53b of the chamber 24 are formed.

又，除霜配管蓋體58也可以係覆蓋除霜配管53與冷卻室57之接合處53a，或者，除霜配管53與機械室24之接合處53b之任一者之構造。藉此，可抑制排水自接合處53a或接合處53b，浸入聚氨酯發泡體16。In addition, the defrost piping cover 58 may be configured to cover either the joint 53a of the defrost piping 53 and the cooling chamber 57 or any one of the joint 53b of the defrosting piping 53 and the machine room 24. As a result, it is possible to prevent the drainage from entering the polyurethane foam 16 from the joint 53a or the joint 53b.

又，除霜配管蓋體58也可以係覆蓋接合處53a及接合處53b兩者之構造。藉此，可更確實抑制排水浸入聚氨酯發泡體16。In addition, the defrost piping cover 58 may have a structure that covers both the joint 53a and the joint 53b. As a result, it is possible to more reliably suppress the infiltration of drain water into the polyurethane foam 16.

第7圖係設有除霜配管用加熱器56之除霜配管蓋體58之立體圖；第8圖係除霜配管用加熱器56之展開圖。FIG. 7 is a perspective view of a defrosting piping cover 58 provided with a heater 56 for defrosting piping; FIG. 8 is a developed view of the heater 56 for defrosting piping.

如第7圖及第8圖所示，除霜配管用加熱器56係由加熱線56a與片狀之鋁板56b所構成，被捲繞在圓筒狀之除霜配管蓋體58上。除霜配管用加熱器56係被設成鋁板56b的一邊之面，接觸到除霜配管蓋體58的外周面。As shown in FIG. 7 and FIG. 8, the heater 56 for the defrosting piping is composed of a heating wire 56a and a sheet-shaped aluminum plate 56b, and is wound around the cylindrical defrosting piping cover 58. The heater 56 for the defrosting piping is provided on one side of the aluminum plate 56b, and contacts the outer peripheral surface of the defrosting piping cover 58.

加熱線56a係被彎折，其被配置於鋁板56b的另一邊之面，亦即，綿延在不接觸到除霜配管蓋體58的外周面之側之表面全體。加熱線56a係在鋁板56b之法線方向上，加熱線56a的一部份與另一部分不相重疊。The heating wire 56a is bent, and is arranged on the other surface of the aluminum plate 56b, that is, the entire surface extending on the side that does not contact the outer peripheral surface of the defrost piping cover 58. The heating wire 56a is in the normal direction of the aluminum plate 56b, and one part of the heating wire 56a does not overlap with the other part.

鋁板56b係捲繞在除霜配管蓋體58的外周面，使得相向之一組之邊沿著除霜配管蓋體58的圓周方向，另外一組之邊沿著除霜配管蓋體58的軸向。鋁板56b的相向之一組之邊之尺寸，係與除霜配管蓋體58的圓周方向之尺寸相比較下，僅小第7圖中之尺寸A。鋁板56b的另外一組之邊之一者，係當除霜配管用加熱器56捲繞在除霜配管蓋體58後，與鋁板56b的另外一組之邊之另一者不相重疊。尺寸A係鋁板56b的另外一組之邊之一者，與另外一組之邊之另一者不相重疊之尺寸，至少係大於零之值。尺寸A係只要至少小於除霜配管蓋體58的半周即可，其最好盡量小。 The aluminum plate 56b is wound around the outer peripheral surface of the defrosting pipe cover 58 such that the side of one set is along the circumferential direction of the defrosting pipe cover 58 and the other side is along the axial direction of the defrosting pipe cover 58. The size of the opposite side of the aluminum plate 56b is smaller than the size A in Figure 7 in comparison with the size of the defrost piping cover 58 in the circumferential direction. One of the edges of the other set of aluminum plates 56b is such that when the heater 56 for the defrost piping is wound around the defrosting pipe cover 58, it does not overlap with the other of the edges of the other set of aluminum plates 56b. The dimension A is one of the sides of the other group of the aluminum plate 56b, and the dimension that does not overlap with the other of the sides of the other group is at least a value greater than zero. As long as the dimension A is at least smaller than half the circumference of the defrost piping cover 58, it is preferably as small as possible.

如此一來，藉在除霜配管蓋體58的外周捲繞有除霜配管用加熱器56，排水被除霜配管蓋體58擋住，可防止排水與除霜配管用加熱器56之接觸。 In this way, by winding the heater 56 for the defrosting pipe around the outer periphery of the defrosting pipe cover 58, the drain is blocked by the defrosting pipe cover 58, and the contact between the drain and the heater 56 for the defrosting pipe can be prevented.

如上所述，除霜配管用加熱器56係被配置成加熱線56a們係不彼此重疊，當捲繞在除霜配管蓋體58後，鋁板56b們也不相重疊。藉此，可抑制除霜配管蓋體58之局部性溫度上昇，可防止除霜配管蓋體58因為熱而變形或熔解。 As described above, the heater 56 for the defrosting piping is arranged so that the heating wires 56a do not overlap each other, and when wound around the defrosting piping cover 58, the aluminum plates 56b do not overlap. As a result, the local temperature rise of the defrost piping cover 58 can be suppressed, and the defrosting piping cover 58 can be prevented from being deformed or melted due to heat.

除霜配管用加熱器56係持續維持沿著除霜配管蓋體58圓周方向之相向一組之邊之尺寸，與除霜配管蓋體58圓周方向之尺寸之差為尺寸A，而且，盡量使尺寸A較小。藉此，除霜配管用加熱器56與霜配管蓋體58之接觸面積變得較廣，變得熱可以效率良好地自除霜配管用加熱器56進入除霜配管蓋體58及除霜配管53。 The heater 56 for the defrosting piping continues to maintain the size of the group of edges along the circumferential direction of the defrosting piping cover 58, and the difference from the circumferential dimension of the defrosting piping cover 58 is the dimension A, and, as much as possible, The size A is smaller. As a result, the contact area between the defrosting piping heater 56 and the frost piping cover 58 becomes wider, and the heat can be efficiently entered from the defrosting piping heater 56 into the defrosting piping cover 58 and the defrosting piping. 53.

除霜配管用加熱器56係被配置於除霜配管蓋體58及除霜配管53，同時被配置於第一真空絕熱材54與第二真空絕熱材55之間，除霜配管用加熱器56之熱較難釋出到外部。因此，熱可以效率良好地自除霜配管用加熱器56進入除霜配管蓋體58及除霜配管53。而且，除霜配管用加熱器56雖然也可以採用在外箱52未設有第一真空絕熱材54之構造，但是，如果設有第一真空絕熱材54時，可更確實抑制熱釋出到除霜配管用加熱器56的外部。 The heater 56 for the defrosting piping is arranged between the defrosting piping cover 58 and the defrosting piping 53, and between the first vacuum insulation material 54 and the second vacuum insulation material 55, and the heater 56 for the defrosting piping The heat is more difficult to release to the outside. Therefore, heat can efficiently enter the defrosting piping cover 58 and the defrosting piping 53 from the defrosting piping heater 56. In addition, although the heater 56 for defrosting piping may have a structure in which the first vacuum insulation material 54 is not provided in the outer box 52, if the first vacuum insulation material 54 is provided, heat release to the The outside of the frost piping heater 56.

當依據以上說明過之實施形態4之冰箱1時，冷卻室57與除霜配管53之接合處53a、及除霜配管53與機械室24之接合處53b，係被除霜配管蓋體58覆蓋。因此，即使排水自接合處53a或接合處53b洩漏時，也可以抑制聚氨酯發泡體16浸水所致之絕熱性能惡化，而且，也可以防止由聚氨酯發泡體16之膨潤所致之變形。According to the refrigerator 1 of the fourth embodiment described above, the joint 53a of the cooling chamber 57 and the defrosting piping 53 and the joint 53b of the defrosting piping 53 and the mechanical chamber 24 are covered by the defrosting piping cover 58 . Therefore, even when drain water leaks from the joint 53a or the joint 53b, the deterioration of the thermal insulation performance caused by the immersion of the polyurethane foam 16 can be suppressed, and the deformation caused by the swelling of the polyurethane foam 16 can also be prevented.

又，在除霜配管蓋體58外周設有除霜配管用加熱器56，藉此，即使排水自接合處53a及接合處53b洩漏，排水也被除霜配管蓋體58擋住，可防止接觸到除霜配管用加熱器56。因此，除霜配管用加熱器56變得無須施行防水處置等，可提案一種可以抑制除霜配管53之凍結，同時較便宜且安全性高之冰箱1。In addition, a heater 56 for defrosting piping is provided on the outer periphery of the defrosting piping cover 58, whereby even if drain water leaks from the joint 53a and the joint 53b, the drain is blocked by the defrosting piping cover 58 to prevent contact Defrost piping heater 56. Therefore, the heater 56 for the defrosting piping does not need to be subjected to waterproofing, etc., and it is possible to propose a refrigerator 1 that can suppress freezing of the defrosting piping 53 and is relatively inexpensive and highly safe.

而且，實施形態4之除霜配管蓋體58及除霜配管用加熱器56，係也可以與實施形態1～3之構造相組合。Furthermore, the defrosting piping cover 58 and the defrosting piping heater 56 of the fourth embodiment may be combined with the structures of the first to third embodiments.
