參閱圖1，該冷凍室箱體4例如為方體但不以此為限，並界定出一開口向前的冷凍空間41。該冷凍空間41設有圖中未示出且對準該風扇3的入風口，並具有一形成於該冷凍室箱體4的後側且連通該製冷空間11的冷凍室回風口結構411。該冷凍室回風口結構411位於該冷凍室箱體4的底部且對準該熱交換裝置2，而能讓該冷凍空間41內的氣體經由該製冷空間11導引至該熱交換裝置2。在本實施例中，該冷凍室回風口結構411的高度低於該冷凍空間41的入風口高度，使該冷凍空間41內的冷卻循環方式是由上而下流動。此外，該冷凍室回風口結構411是以多個狹縫示例，但該冷凍室回風口結構411也可以是單一孔洞，視實際需求而定。 Referring to FIG. 1 , the freezer box 4 is, for example, but not limited to a rectangular body, and defines a freezing space 41 that opens forward. The freezing space 41 is provided with an air inlet not shown in the figure and aligned with the fan 3 , and has a freezing chamber return air inlet structure 411 formed on the rear side of the freezing chamber box 4 and connected to the refrigeration space 11 . The freezer return air outlet structure 411 is located at the bottom of the freezer box 4 and is aligned with the heat exchange device 2, so that the gas in the freezing space 41 can be guided to the heat exchange device 2 through the refrigeration space 11. In this embodiment, the height of the freezer return air inlet structure 411 is lower than the height of the air inlet of the freezing space 41 so that the cooling circulation in the freezing space 41 flows from top to bottom. In addition, the freezer compartment return air outlet structure 411 is exemplified by multiple slits, but the freezer compartment return air outlet structure 411 can also be a single hole, depending on actual needs.

參閱圖1，該冷藏室箱體5例如為長方體但不以此為限且裝設於該冷凍室箱體4的下方，並界定出一開口向前且與該冷凍空間41分隔的冷藏空間51。該冷藏空間51內的溫度高於該冷凍空間41。該冷藏室回風通道6連通該冷藏空間51，並包括一連通該製冷空間11的回風通道出口61。該回風通道出口61位於該冷凍室回風口結構411的下方且與該冷凍室回風口結構411位於該製冷空間11的同一側。也就是說，該回風通道出口61與該冷凍室回風口結構411皆朝向後方以將氣體導引至該熱交換裝置2。在本實施例中，該冷藏室回風通道6呈長條狀，且該冷藏室回風通道6是自該冷藏室箱體5的頂部的前側朝後上方延伸至該製冷空間11的底部，而能讓該冷藏空間51內受外界影響而升溫的氣體由下而上流回至該製冷空間11。然而，該冷藏室回風通道6也可以僅是形成於該冷藏室箱體5的一側壁且與該製冷空間11連通的開口(即該回風通道出口61)，不以特定形式為限。 Referring to Figure 1, the refrigerator box 5 is, for example, but not limited to a rectangular parallelepiped and is installed below the freezer box 4 and defines a refrigerator space 51 that opens forward and is separated from the freezer space 41. . The temperature in the refrigerating space 51 is higher than that in the freezing space 41 . The refrigeration room return air channel 6 is connected to the refrigeration space 51 and includes a return air channel outlet 61 connected to the refrigeration space 11 . The return air channel outlet 61 is located below the freezing chamber return air opening structure 411 and is located on the same side of the refrigeration space 11 as the freezing chamber return air opening structure 411 . That is to say, the return air channel outlet 61 and the freezer chamber return air inlet structure 411 are both directed toward the rear to guide gas to the heat exchange device 2 . In this embodiment, the refrigerating room return air channel 6 is in a long strip shape, and the refrigerating room return air channel 6 extends from the front side of the top of the refrigerating room box 5 toward the rear and upward to the bottom of the refrigeration space 11. The gas in the refrigerated space 51 that has been heated by external influences can flow back to the refrigerated space 11 from bottom to top. However, the refrigerating room return air channel 6 can also be only an opening (ie, the return air channel outlet 61 ) formed on a side wall of the refrigerating room box 5 and communicated with the refrigeration space 11 , and is not limited to a specific form.

參閱圖1與圖2，該擋板7呈現為長方形但不以此為限，並設置於該製冷空間11且位於該冷凍室回風口結構411與該回風通道出口61之間。該擋板7用以阻隔氣體自該回風通道出口61流向該冷凍室回風口結構411。更具體來說，該擋板7自該冷藏室回風通道6的頂緣的後側向後橫向延伸，而能有效阻隔氣體自該回風通道出口61流向該冷凍室回風口結構411。但該擋板7也可以是自位於該冷藏室回風通道6上方的該冰箱殼體1的一部份向後延伸，或者是自該冷凍室箱體4的底緣向後延伸，視實際需求而定。 Referring to FIGS. 1 and 2 , the baffle 7 is rectangular in shape but is not limited thereto, and is disposed in the refrigeration space 11 and between the freezer return air outlet structure 411 and the return air channel outlet 61 . The baffle 7 is used to block the air from flowing from the return air channel outlet 61 to the freezer return air outlet structure 411 . More specifically, the baffle 7 extends rearward and laterally from the rear side of the top edge of the refrigerator compartment return air channel 6, and can effectively block the flow of gas from the return air channel outlet 61 to the freezer compartment return air outlet structure 411. However, the baffle 7 can also extend rearward from a part of the refrigerator casing 1 located above the refrigerating room return air channel 6, or extend rearward from the bottom edge of the freezer box 4, depending on actual needs. Certainly.

參閱圖1與圖2，該隔板8設置於該製冷空間11且位於該冷凍室回風 口結構411與該熱交換裝置2之間。更具體來說，該隔板8呈倒L字形，且該隔板8的一側連接於該冷凍室箱體4的後側且位於該冷凍室回風口結構411的上方，而該隔板8的另一側豎立於該冷凍室回風口結構411與該熱交換裝置2之間，而能將該製冷空間11分隔成一鄰近該冷凍室回風口結構411且開口向下的延伸通道部111，及一供該熱交換裝置2設置的製冷通道部112。在本實施例中，該隔板8底緣的高度低於該冷凍室回風口結構411的高度，使得來自該冷凍室回風口結構411的氣體被該隔板8限制而無法直接吹向該熱交換裝置2，並讓該延伸通道部111產生一向下流動的氣流，而阻隔氣體自該回風通道出口61向上流至該冷凍室回風口結構411。此外，該延伸通道部111的開口的前側部分會被該擋板7遮蔽，以避免來自該回風通道出口61的氣體流至該冷凍室回風口結構411。 Referring to Figures 1 and 2, the partition 8 is disposed in the refrigeration space 11 and is located between the return air of the freezing chamber and between the port structure 411 and the heat exchange device 2. More specifically, the partition 8 is in an inverted L shape, and one side of the partition 8 is connected to the rear side of the freezer box 4 and is located above the freezer return air outlet structure 411 , and the partition 8 The other side is erected between the freezer return air outlet structure 411 and the heat exchange device 2, and can divide the refrigeration space 11 into an extended channel portion 111 adjacent to the freezer return air outlet structure 411 and opening downward, and A refrigeration channel portion 112 for the heat exchange device 2 to be provided. In this embodiment, the height of the bottom edge of the partition 8 is lower than the height of the freezer return air outlet structure 411, so that the gas from the freezer return air outlet structure 411 is restricted by the partition 8 and cannot be blown directly to the heat sink. The exchange device 2 allows the extended channel portion 111 to generate a downward flow of air, and the blocking gas flows upward from the return air channel outlet 61 to the freezer compartment return air inlet structure 411 . In addition, the front side portion of the opening of the extension channel portion 111 will be shielded by the baffle 7 to prevent the air from the return air channel outlet 61 from flowing to the freezer compartment return air inlet structure 411 .

參閱圖1與圖2，以下，具體說明該冰箱的冷卻循環方式。首先，該風扇3會受到控制電路模組驅動運轉而產生抽氣效果，帶動該製冷空間11內的氣體由下而上流經該熱交換裝置2，以進行氣體的冷熱交換，讓氣體的溫度降低。接著，該風扇3會將冷卻後的氣體由後向前吹送至該冷凍空間41，再讓低溫氣體由該冷凍空間41流至該冷藏空間51，或者該風扇3會將冷卻後的氣體經由圖中未示出的其他冷卻通道吹送至該冷藏空間51，以讓該冷凍空間41與該冷藏空間51的溫度維持在設定值。然後，藉由熱對流機制以及該風扇3持續抽氣，該冷藏空間51內的溫度較高的氣體會受到該冷藏室回風通道6的導引，經由該回風通道出口61流至該製冷空間11。並且，來自該回風通道出口61的氣體會受到位於上方且橫向延伸的該擋板7阻隔與導引，而向後方流動至該製冷空間11 的製冷通道部112。同時，該冷凍空間41內的溫度較高的氣體也會受到該風扇3持續抽氣的影響，而自該冷凍室回風口結構411流出，並且受到該延伸通道部111導引而流動至該製冷空間11的製冷通道部112。最後，來自該回風通道出口61且受到該擋板7導引的氣體與來自該冷凍室回風口結構411且受到該延伸通道部111導引的氣體皆會流向該製冷通道部112而能夠再次被該風扇3帶動通過該熱交換裝置2，以完成該冰箱的冷卻循環路徑。 Referring to Figures 1 and 2, the cooling cycle method of the refrigerator will be described in detail below. First, the fan 3 will be driven by the control circuit module to produce an air extraction effect, driving the gas in the refrigeration space 11 to flow through the heat exchange device 2 from bottom to top, so as to exchange heat and cold of the gas and reduce the temperature of the gas. . Then, the fan 3 will blow the cooled gas from back to front to the freezing space 41, and then allow the low-temperature gas to flow from the freezing space 41 to the refrigerated space 51, or the fan 3 will blow the cooled gas through the figure. Other cooling channels not shown in are blown to the refrigerated space 51 to maintain the temperatures of the freezing space 41 and the refrigerated space 51 at the set value. Then, through the thermal convection mechanism and the continuous extraction of air by the fan 3, the gas with a higher temperature in the refrigerated space 51 will be guided by the return air channel 6 of the refrigerated room and flow to the refrigeration room through the return air channel outlet 61. Space 11. Moreover, the gas from the return air channel outlet 61 will be blocked and guided by the baffle 7 located above and extending laterally, and flow backward to the refrigeration space 11 refrigeration channel portion 112. At the same time, the higher-temperature gas in the freezing space 41 will also be affected by the continuous extraction of the fan 3, flow out from the freezing chamber return air outlet structure 411, and be guided by the extended channel portion 111 to flow to the refrigeration room. The refrigeration passage portion 112 of the space 11. Finally, the gas from the return air channel outlet 61 and guided by the baffle 7 and the gas from the freezer return air outlet structure 411 and guided by the extended channel portion 111 will flow to the refrigeration channel portion 112 and can be used again. It is driven by the fan 3 through the heat exchange device 2 to complete the cooling circulation path of the refrigerator.

綜上所述，藉由設置該擋板7，能阻隔該冷藏室回風通道6的氣體流入該冷凍空間41，讓該冷凍空間41的溫度未受到干擾而維持不變，進而減少該壓縮機的作動頻率以達到節能的效果，故確實能達成本發明的目的。 To sum up, by arranging the baffle 7, the gas in the return air channel 6 of the refrigerator compartment can be blocked from flowing into the freezing space 41, so that the temperature of the freezing space 41 can be maintained unchanged without being disturbed, thereby reducing the need for the compressor to The operating frequency can achieve the effect of energy saving, so the purpose of the present invention can indeed be achieved.
