Description
本發明係關於具有製冰裝置的冷凍冷藏庫。 The present invention relates to a freezer refrigerator having an ice making device.
過去，已知有具有自動製冰的自動製冰裝置的冰箱。 In the past, refrigerators having automatic ice making devices for automatic ice making have been known.
如上述的產品有：在冷凍室內設置自動製冰裝置，將冷氣從用於將冷氣送到冷凍室內的吹出口吹出冷氣，並且，藉由與此物出口不同，另外設置的冷氣通路，將冷氣吹出到製冰皿上面(例如參見專利文獻1)。 The product as described above includes: an automatic ice making device is disposed in the freezing chamber, and cold air is blown out from the air outlet for sending the cold air to the freezing chamber, and the cold air passage is additionally provided by the cold air passage provided separately from the object outlet. Blow out onto the ice tray (see, for example, Patent Document 1).
另外，將供應至製冰室的製冰裝置的冷氣的風路做成：主風路和許多的副風路分離，「藉由主風路21，將冷氣從製冰皿11的後方供應到製冰皿11的前端部」，並且，「通過副風路22以及副風路23的冷氣，透過複數個開口部17，從製冰皿11的斜上方供應到製冰皿11」(例如參見專利文獻2)。 Further, the air passage of the cold air supplied to the ice making device of the ice making compartment is formed such that the main air passage is separated from the plurality of auxiliary air passages, "the main air passage 21 supplies the cold air from the rear of the ice tray 11 to The front end portion of the ice tray 11 and the "cool air passing through the sub air passage 22 and the auxiliary air passage 23 are supplied through the plurality of openings 17 from the oblique upper side of the ice tray 11 to the ice tray 11" (see, for example, Patent Document 2).
另外，將冷氣從形成為與送出冷氣的送風機相對的吹出口吹出到冷凍室內，同時，將冷氣從設置於該吹出口上方的冷氣流路管連通之複數個吹出口吹出到製冰皿(例如參見專利文獻3)。 Further, the cold air is blown out from the air outlet formed to face the blower that sends out the cool air into the freezing chamber, and the cold air is blown out from the plurality of air outlets that are connected to the cold air flow pipe provided above the air outlet to the ice tray (for example, See Patent Document 3).

專利文獻2：特開2010-43323號公報(第7-9頁、第5 圖) Patent Document 2: JP-A-2010-43323 (pages 7-9, 5) Figure)

不過，在製冰皿裡做冰的時候，從製冰皿上方噴冷氣直接地進行冷卻，會比從製冰皿的周圍間接進行冷卻的製冰效率更好。 However, when ice is made in an ice tray, direct cooling from the top of the ice tray will result in better ice making efficiency than indirect cooling from around the ice tray.
上述專利文獻1中所記載者，具有位於冷凍室後方製冰皿下方及製冰皿上方的二個吹出口，所以，從送風機吹出的冷氣流量分散於二個吹出口。因此，從為直接冷卻製冰皿而設置於製冰皿上方的吹出口之冷氣流量相對地變小，而使得難以提升製冰效率。 The above-described Patent Document 1 has two outlets located below the ice tray and above the ice tray, so that the flow rate of the cold air blown from the blower is dispersed in the two outlets. Therefore, the flow rate of the cold air from the air outlet provided above the ice tray for directly cooling the ice tray is relatively small, making it difficult to improve the ice making efficiency.
另外上述專利文獻2所記載者，具有從製冰皿的後方到前方提供冷氣的主風路、以及從製冰皿的斜上方向製冰皿提供冷氣的副風路。但是，因為來自主風路的冷氣和來自副風路的冷氣交會，所以流量相對較小的副風路的冷氣會因為來自主風路的冷氣而改變其流動方向，而使得製冰效率下降。 Further, in the above-described Patent Document 2, there is provided a main air passage for supplying cold air from the rear to the front of the ice tray, and a sub-wind passage for supplying cold air from the obliquely upward direction of the ice tray. However, since the cold air from the main air path and the cold air from the auxiliary air path meet, the cold air of the sub air path having a relatively small flow rate changes the flow direction due to the cold air from the main air path, and the ice making efficiency is lowered.
此外，在專利文獻1、3中所記載者，係構成為：使來自送風機的冷氣，先導向與送風機的冷氣送風方向約略垂直的方向，再將冷氣從製冰皿用的吹出口吹出至製冰皿的上面。因此，從送風機到製冰皿用的吹出口之冷氣的流動不佳，壓力損失大，相對於送風機吹出的送風量，供應到 製冰皿的送風量減少，而降低製冰效率。 Further, in Patent Documents 1 and 3, the cold air from the blower is first guided to a direction perpendicular to the direction in which the cold air is blown from the blower, and the cold air is blown out from the air outlet for the ice tray. Above the ice dish. Therefore, the flow of the cold air from the blower to the blower for the ice tray is poor, and the pressure loss is large, and is supplied to the air blower blown by the blower. The air supply volume of the ice tray is reduced, and the ice making efficiency is lowered.
如上述，在傳統的具有製冰裝置的冷凍冷藏庫中，期望更進一步改善製冰效率。 As described above, in the conventional freezer refrigerator having the ice making device, it is desirable to further improve the ice making efficiency.
本發明係以上述課題為背景，其目的在於提供使製冰室的製冰效率提升的冷凍冷藏庫。 The present invention has been made in view of the above problems, and an object thereof is to provide a refrigerator-freezer that improves the ice making efficiency of an ice making room.

The user can pull out or press the ice tray 1 from the frame 10 by operating the lock lever 9 to release the restriction. Further, the ice tray 1 is configured to be detachable from the frame 10. Therefore, the user operates the lock lever 9 that fixes the ice tray 1, pulls out the ice tray 1 and detaches it from the frame 10, whereby the ice tray 1 can be taken out from the ice making chamber 300, and can be cleaned, etc. action.
另外，在製冰皿1背面側，設置連接於驅動裝置4的旋轉軸13(參照第3圖)。 Further, a rotating shaft 13 connected to the driving device 4 is provided on the back side of the ice tray 1 (see FIG. 3).
驅動裝置4，內建有旋轉驅動旋轉軸13的馬達以及減速齒輪，由圖未顯示的控制裝置控制，以使旋轉軸13旋轉讓製冰皿1翻轉。藉此，製冰皿1內的冰落下並存放在儲冰盒5中。此外，為了促使製冰皿1中冰的脫離，也可以加上用以在製冰皿1翻轉的時候施加扭轉的已知的構成。 The drive unit 4 is internally provided with a motor that rotationally drives the rotary shaft 13 and a reduction gear, and is controlled by a control device not shown, so that the rotary shaft 13 is rotated to cause the ice tray 1 to be reversed. Thereby, the ice in the ice tray 1 falls and is stored in the ice bank 5. Further, in order to promote the detachment of ice in the ice tray 1, a known configuration for applying a twist when the ice tray 1 is turned over may be added.
另外，驅動裝置4上，安裝有可轉動的檢冰桿8。檢冰桿8係用以檢出儲冰盒5中冰的量。檢冰桿8的尖端在上下方向移動，藉此，測定儲冰盒5內部之冰的高度，而能夠檢測出儲冰盒5內部冰的量。 Further, a rotatable ice detecting lever 8 is attached to the driving device 4. The ice detector 8 is used to detect the amount of ice in the ice bank 5. The tip end of the ice detecting bar 8 is moved in the vertical direction, whereby the height of the ice inside the ice bank 5 is measured, and the amount of ice inside the ice bank 5 can be detected.
導風盤2的上方設有給水管6，用以將給水槽內的水 供應到製冰皿1中。在本實施形態中，給水槽(圖未顯示)係配置於冷藏室200內的分隔壁41的上方，給水管6和給水槽連接並插通於分隔壁41。給水槽內的水經過給水管6供應至製冰皿1。此外，給水槽的配置並不以此為限，例如在製冰室300內形成被隔熱材包圍的分隔空間，並將給水槽配置於該分隔空間中亦可。 A water supply pipe 6 is provided above the air guiding plate 2 for water in the water supply tank It is supplied to the ice tray 1. In the present embodiment, a water supply tank (not shown) is disposed above the partition wall 41 in the refrigerating compartment 200, and the water supply pipe 6 and the water supply tank are connected to each other and inserted into the partition wall 41. The water in the water tank is supplied to the ice tray 1 through the water supply pipe 6. Further, the arrangement of the water tank is not limited thereto, and for example, a partition space surrounded by the heat insulating material may be formed in the ice making chamber 300, and the water tank may be disposed in the partition space.
另外，在導風盤2上方，設有熱電堆7，以作為檢出製冰皿1內的水的溫度的溫度查出裝置。 Further, above the wind deflector 2, a thermopile 7 is provided as a temperature detecting means for detecting the temperature of the water in the ice making tray 1.
導風盤2包括：周壁21、底板22、形成於底板22的吹出口23、間壁24。在導風盤2下方，形成收容空間25(參照第5圖)，製冰皿1即配置於收容空間25中。 The air guide disk 2 includes a peripheral wall 21, a bottom plate 22, an air outlet 23 formed in the bottom plate 22, and a partition wall 24. Below the wind deflector 2, a housing space 25 is formed (see FIG. 5), and the ice tray 1 is disposed in the housing space 25.
導風盤2之背面側連接製冰室300的流入口302。在導風盤2和流入口302的連接部分，兩者的寬度大至相同，不過導風盤2係構成為，從該連接部分開始，越靠近近端部的寬度漸漸變大的形狀。使其寬度變大而延伸的周壁21，有時也稱為擴大部21a。 The back side of the wind guide tray 2 is connected to the inflow port 302 of the ice making compartment 300. The width of the connecting portion between the wind deflector 2 and the inflow port 302 is substantially the same, but the wind deflector 2 is configured such that the width of the proximal end portion gradually increases from the connecting portion. The peripheral wall 21 that has a widened width and is sometimes referred to as an enlarged portion 21a.
間壁24係配置於導風盤2的左右方向之約略中央處，其係形成為背面側為曲面之平面觀之略成U字形的壁。在導風盤2內由間壁24圍住的內部，並未設置底板22，而在底面形成開口部6a。該間壁24係用以將給水管6和熱電堆7配置在製冰皿1上方的構造。樣這樣，在導風盤2設置不具有被間壁24圍住的底面之構造，藉此，如第7~9圖所示，可以將給水管6和熱電堆7配置在間壁24圍住的內側。因為可以將給水管6配置在靠近製冰皿1的上方， 所以能夠將給水管6從配置於製冰裝置310上方的給水槽直直伸出，而能夠縮短給水路徑。另外，因為能夠將熱電堆7配置在靠近製冰皿1上方，所以能夠在貼近製冰皿1進行精確的溫度測量。 The partition wall 24 is disposed at approximately the center of the right and left direction of the wind deflector 2, and is formed in a substantially U-shaped wall having a plan view of the back side. In the inside of the wind guide tray 2 surrounded by the partition wall 24, the bottom plate 22 is not provided, and the opening portion 6a is formed in the bottom surface. The partition wall 24 is a structure for arranging the water supply pipe 6 and the thermopile 7 above the ice tray 1. In this way, the wind deflector 2 is provided with a structure having no bottom surface surrounded by the partition wall 24, whereby the water supply pipe 6 and the thermopile 7 can be disposed around the partition wall 24 as shown in Figs. The inside. Because the water supply pipe 6 can be placed close to the ice tray 1, Therefore, the water supply pipe 6 can be directly extended from the water supply tank disposed above the ice making device 310, and the water supply path can be shortened. In addition, since the thermopile 7 can be disposed close to the ice tray 1, accurate temperature measurement can be performed close to the ice tray 1.
而且，藉由導風盤2形成入口側風路31、第一風路32以及第二風路33。這些入口側風路31、第一風路32以及第二風路33有時總稱為冷氣風路3。 Further, the inlet side air passage 31, the first air passage 32, and the second air passage 33 are formed by the air guiding disc 2. The inlet side air passage 31, the first air passage 32, and the second air passage 33 are sometimes collectively referred to as a cold air passage 3.
入口側風路31，係連接於流入口302，大致上來說，是存在於從流入口302到間壁24的背面側端部的風路。從流入口302吹出的冷氣，首先會流進入口側風路31。該入口側風路31，包含對應於擴大部21a的風路(流路擴大部)。 The inlet side air passage 31 is connected to the inflow port 302, and is substantially an air path existing from the inflow port 302 to the rear end portion of the partition wall 24. The cold air blown from the inflow port 302 first flows into the port side air passage 31. The inlet side air passage 31 includes an air passage (flow path expanding portion) corresponding to the enlarged portion 21a.
第一風路32，係連接於入口側風路31，大致上來說，是形成於間壁24的左側部分和周壁21的左側部分之間的風路。該第一風路32係配置為約略對應於製冰皿1上並排設置的冰室11中的配置於左側的列之冰室11。 The first air passage 32 is connected to the inlet side air passage 31, and is substantially an air passage formed between the left side portion of the partition wall 24 and the left side portion of the peripheral wall 21. The first air passages 32 are arranged to correspond approximately to the ice chambers 11 arranged in the left side of the ice chambers 11 arranged side by side on the ice tray 1.
第二風路33，係連接於入口側風路31，大致上來說，是形成於間壁24的右側部分和周壁21的右側部分之間的風路。該第二風路33係配置為約略對應於製冰皿1上並排設置的冰室11中的配置於右側的列之冰室11。 The second air passage 33 is connected to the inlet side air passage 31, and is substantially an air passage formed between the right side portion of the partition wall 24 and the right side portion of the peripheral wall 21. The second air passages 33 are arranged to correspond approximately to the ice chambers 11 arranged in the right side of the ice chambers 11 arranged side by side on the ice tray 1.
從流入口302提供的冷氣，首先會流進入口側風路31，流進入口側風路31的冷氣的一部分流入第一風路32，其他的則流入第二風路33。 The cold air supplied from the inflow port 302 first flows into the port side air passage 31, and a part of the cold air flowing into the port side air passage 31 flows into the first air passage 32, and the other flows into the second air passage 33.
在此，入口側風路31包括對應於擴大部21a的風路。相對於在流入口302的冷氣的流路截面積，入口側風路31 中的冷氣的流路截面積被擴大(流路擴大部)。亦即，擴大部21a是用以使得導風盤2的流路截面積相對於流入口302的冷氣的流路截面積擴大之構成的一個例子。之所以要像這樣讓流路截面積擴大，是為了使冷氣的流速無限制地接近0(零)。藉此，藉由導風盤2上方和下方(製冰皿1側)的壓力差、以及導風盤2的吹出口23的開口面積，就能調整從各吹出口23提供的冷氣的流量。 Here, the inlet side air passage 31 includes an air passage corresponding to the enlarged portion 21a. The inlet side air passage 31 with respect to the flow path sectional area of the cold air at the inflow port 302 The flow path cross-sectional area of the cold air is expanded (flow path expansion unit). In other words, the enlarged portion 21a is an example of a configuration for increasing the cross-sectional area of the flow path of the air guide disk 2 with respect to the flow path cross-sectional area of the cold air of the inflow port 302. The reason why the cross-sectional area of the flow path is enlarged like this is to make the flow rate of the cold air close to zero (zero) without limitation. Thereby, the flow rate of the cold air supplied from each of the air outlets 23 can be adjusted by the pressure difference between the upper and lower sides of the air deflector 2 (the side of the ice tray 1) and the opening area of the air outlet 23 of the air deflector 2.
此外，在本實施形態中，係揭露如第6圖所示之在紙面左側的周壁21設置擴大部21a的例子，但是擴大部21a也可以設置在右側的周壁21上，也可以在左右兩方的周壁21上設置擴大部21a。不論是何種方式，只要是相對於和流入口302的接續部分，左右面對的周壁21彼此之間的間隔擴大的構成即可。 Further, in the present embodiment, an example in which the enlarged portion 21a is provided on the peripheral wall 21 on the left side of the paper surface as shown in Fig. 6 is disclosed. However, the enlarged portion 21a may be provided on the right side peripheral wall 21, or may be on the left and right sides. The enlarged portion 21a is provided on the peripheral wall 21. In any case, as long as it is a connection portion with the inflow port 302, the interval between the right and left peripheral walls 21 may be increased.
另外，在本實施形態中，係揭露用擴大部21a來擴大相對的周壁21之間的間隔，藉此擴大導風盤2的流路截面積的例子，不過也可以藉由使導風盤2的高度相對於流入口302的高度更高，來擴大流路截面積。 Further, in the present embodiment, the expansion portion 21a is used to expand the interval between the opposing peripheral walls 21, thereby expanding the flow path cross-sectional area of the wind deflector 2, but the wind deflector 2 may be provided. The height is higher relative to the height of the inflow port 302 to expand the flow path cross-sectional area.
另外，如第9圖所示，周壁21和間壁24為大致相同的高度。而且，在製冰裝置310設置於製冰室300內的狀態下，周壁21和間壁24的上端接觸製冰室300的頂面。因此，被間壁24圍住的內側，基本上並不和入口側風路31、第一風路32、第二風路33連通，來自這些風路的冷氣並不直接流入。亦即，間壁24和製冰室300的頂面係作為阻擋導風盤2上的冷氣從吹出口23以外流入製冰皿1側 的阻擋部。 Further, as shown in Fig. 9, the peripheral wall 21 and the partition wall 24 have substantially the same height. Further, in a state where the ice making device 310 is disposed in the ice making chamber 300, the upper ends of the peripheral wall 21 and the partition wall 24 contact the top surface of the ice making chamber 300. Therefore, the inner side surrounded by the partition wall 24 does not substantially communicate with the inlet side air passage 31, the first air passage 32, and the second air passage 33, and the cold air from these air passages does not directly flow. That is, the partition wall 24 and the top surface of the ice making chamber 300 serve as a barrier to the cold air on the air deflector 2 from the outside of the air outlet 23 into the side of the ice tray 1 The barrier.
複數個吹出口23開口在導風盤2的底板22上。另外，在本實施形態中，吹出口23的數量和製冰皿1的冰室11的數量相同。另外，吹出口23的位置和製冰皿1的冰室11的配置大致對應，如第6圖所示，6個吹出口23配置為大致沿著導風盤2的長方形方向排成左右2行。 A plurality of blowout ports 23 are opened on the bottom plate 22 of the wind deflector 2. Further, in the present embodiment, the number of the air outlets 23 is the same as the number of the ice chambers 11 of the ice tray 1. Further, the position of the air outlet 23 is substantially corresponding to the arrangement of the ice chamber 11 of the ice tray 1. As shown in Fig. 6, the six air outlets 23 are arranged so as to be arranged substantially in the left and right directions along the rectangular direction of the air guide disk 2.
第10圖為從前面觀看實施形態的製冰裝置，以說明製冰皿和第一風路及第二風路之配置的圖。此外，第10圖中，以二點鎖線Z表示製冰皿1的回轉區域Z。 Fig. 10 is a view showing the ice making device of the embodiment and the arrangement of the first air passage and the second air passage, as seen from the front. Further, in Fig. 10, the rotation area Z of the ice tray 1 is indicated by a two-point lock line Z.
如第10圖所示，第一風路32和第二風路33都配置於製冰皿1的回轉區域Z的外側。 As shown in FIG. 10, both the first air passage 32 and the second air passage 33 are disposed outside the rotation region Z of the ice tray 1.
在導風盤2的底板22，於間壁24的近旁，形成朝向間壁24下端斜地上升的傾斜面22a。該傾斜面22a可以如第10圖所示般為直線的面，也可以為曲面。 In the bottom plate 22 of the air deflector 2, an inclined surface 22a which rises obliquely toward the lower end of the partition wall 24 is formed in the vicinity of the partition wall 24. The inclined surface 22a may be a straight surface as shown in Fig. 10 or may be a curved surface.
而且，吹出口23形成於底板22的傾斜面22a。如第10圖所示，藉由在傾斜面22a設置吹出口23，能在朝向與製冰皿1水面的垂直線X夾角θ 1的方向(第10圖的吹出方向Y)上提供冷氣。此角度θ 1稱為冷氣的吹出角度θ 1。 Further, the air outlet 23 is formed on the inclined surface 22a of the bottom plate 22. As shown in Fig. 10, by providing the air outlet 23 on the inclined surface 22a, cold air can be supplied in a direction (the blowing direction Y in Fig. 10) in the direction of the angle θ 1 with respect to the vertical line X of the water surface of the ice tray 1. This angle θ 1 is referred to as the blowing angle θ 1 of the cold air.
如此，從製冰皿1的水面的斜上方提供冷氣，藉此，將製冰皿1內的水冷卻之後的冷氣不容易滯留在製冰皿1的上部。因此，能夠從吹出口23持續將供應到製冰室300的溫度低的冷氣送到製冰皿1上方，而能夠使用溫度低的冷氣進行效率佳的製冰。 In this way, cold air is supplied from the oblique upper side of the water surface of the ice tray 1, whereby the cold air after cooling the water in the ice tray 1 is less likely to remain in the upper portion of the ice tray 1. Therefore, it is possible to continuously supply the cold air having a low temperature supplied to the ice making chamber 300 from above the ice tray 1 from the air outlet 23, and it is possible to perform ice making with high efficiency using cold air having a low temperature.
此外，考慮到要均勻冷卻製冰皿1的各冰室11，並考 慮到從各吹出口23吹出冷氣不阻礙其他吹出口23的冷氣的流動，能夠分別設定對應於各冰室11的吹出口23的冷氣的吹出角度θ 1。複數個吹出口23之中，一吹出口23的吹出角度θ 1可以和其他的吹出口23的吹出角度θ 1不同，能夠針對各吹出口23設定其吹出角度θ 1(形成吹出口23的傾斜面22a的角度。另外，以冷卻效率的觀點而言，如上述般從斜上方提供冷氣是比較好的，不過，也可以包含吹出角度θ 1為0°，形成為從製冰皿1的水面的垂直方向提供冷氣的吹出口23。例如，吹出角度θ 1可以為0°以上30°以下的值。 In addition, it is considered that the ice chambers 11 of the ice tray 1 are uniformly cooled, and In consideration of the fact that the cold air blown from each of the air outlets 23 does not block the flow of the cold air of the other air outlets 23, the air blowing angle θ 1 corresponding to the air outlets 23 of the respective ice chambers 11 can be set. Among the plurality of air outlets 23, the blowing angle θ1 of one air outlet 23 can be different from the airing angle θ1 of the other air outlets 23, and the blowing angle θ1 can be set for each of the air outlets 23 (the inclination of the air outlet 23 is formed). In addition, from the viewpoint of cooling efficiency, it is preferable to provide cold air from an obliquely upward direction as described above, but may include a blowing angle θ 1 of 0°, which is formed from the surface of the ice tray 1 The vertical direction provides a cooling air outlet 23. For example, the blowing angle θ 1 may be a value of 0° or more and 30° or less.
可以針對各吹出口設定吹出口23的開口面積，以使得製冰皿1的各冰室11均一地冷卻。 The opening area of the air outlet 23 can be set for each of the air outlets so that the ice chambers 11 of the ice tray 1 are uniformly cooled.
在此，從製冰室300的流入口302的距離越遠，來自流入口302的冷氣就越難到達，而且，離冷卻器53的距離也遠。因此，複數個吹出口23之中，距離流入口302遠的(進深方向的近側)，就越難冷卻。因此，如前所述，在入口側風路31中，擴大流路截面積以使冷氣的流速盡量接近0，藉此，調整吹出口23的開口面積，以使得製冰皿1的各冰室11裡製冰時間接近均一。由於吹出口23的開口面積越大冷氣的流量就越大，所以大致上是調整為離流入口302較遠的吹出口23開口面積較大。 Here, the further the distance from the inflow port 302 of the ice making chamber 300, the harder it is to reach the cold air from the inflow port 302, and the distance from the cooler 53 is also far. Therefore, among the plurality of air outlets 23, the distance from the inflow port 302 (near side in the depth direction) is more difficult to cool. Therefore, as described above, in the inlet side air passage 31, the flow passage cross-sectional area is enlarged so that the flow rate of the cold air is as close as possible to 0, whereby the opening area of the air outlet 23 is adjusted so that the ice chambers of the ice tray 1 are made. The ice making time in 11 is close to uniform. Since the flow rate of the cold air is larger as the opening area of the air outlet 23 is larger, the opening area of the air outlet 23 which is adjusted to be farther from the flow inlet 302 is substantially larger.
另外，吹出口23的位置為，比製冰皿1的冰室11垂直上方還要向左右外側偏的位置。之所以要這樣，是為了避開向製冰皿1供水的給水管6和熱電堆7。亦即，調整 其配置，使得從吹出口23提供的冷氣，在供應到製冰皿1時盡量不要吹到給水管6和熱電堆7。 Further, the position of the air outlet 23 is a position which is shifted to the left and right outside from the upper side of the ice chamber 11 of the ice tray 1. The reason for this is to avoid the water supply pipe 6 and the thermopile 7 that supply water to the ice tray 1. That is, adjustment It is configured such that the cold air supplied from the air outlet 23 is not blown to the water supply pipe 6 and the thermopile 7 as much as possible when supplied to the ice tray 1.
第11圖為本發明的實施的形態的冷凍冷藏庫的送風機旁的重要部分斷面模式圖。 Fig. 11 is a schematic cross-sectional view showing an essential part of a refrigerator in a freezer-refrigerator according to an embodiment of the present invention.
如第11圖所示，送風機54配置在冷氣供應風路45的冷凍室500背面。 As shown in Fig. 11, the blower 54 is disposed on the back surface of the freezing compartment 500 of the cool air supply air passage 45.
送風機54係配置於約略和流入口502相面對的位置，以使得其冷氣的送風方向約略和形成於冷凍室500的背面壁的上部部分的流入口502相面對。藉由此種構成，送風機54所送出的冷氣，可以承受較少的壓力損失，而平順地從流入口502流入冷凍室500。藉由此種構成，能夠把更低溫的冷氣有效率地供應到冷凍冷藏庫100中設定溫度最低的冷凍室500中。 The blower 54 is disposed at a position approximately facing the inflow port 502 such that the air blowing direction of the cold air is approximately opposite to the inflow port 502 formed in the upper portion of the rear wall of the freezing compartment 500. With such a configuration, the cold air sent from the blower 54 can withstand less pressure loss and smoothly flow into the freezer compartment 500 from the inflow port 502. With such a configuration, it is possible to efficiently supply the cold air of a lower temperature to the freezer compartment 500 having the lowest set temperature in the freezer-refrigerator 100.
此外，在本實施形態中的送風機54，其冷氣的送風方向，相對於水平面，在製冰室300的流入口302的開口側具有特定角度θ 2的傾斜。藉此，到達製冰室300的流入口302的風路中，冷氣的壓力損失少，能夠更有效地讓冷氣流入流入口302。例如在前述的專利文獻1、3中，送風機的送風方向是水平方向的，而向製冰室的冷氣供應口開口在比送風機更上方處，因此，往製冰室的冷氣的流動和送風機的送風方向幾乎垂直，而造成冷氣供應效率的課題。但是，依據本實施形態，因為可以抑制住從送風機54送往製冰室300的冷氣壓力損失，所以能夠相對地增加向製冰室300的冷氣供應量，在提高製冰效率的同時提升節 能效果。 Further, in the blower 54 of the present embodiment, the air blowing direction of the cold air has a certain angle θ 2 inclination on the opening side of the inflow port 302 of the ice making chamber 300 with respect to the horizontal plane. Thereby, in the air passage which reaches the inflow port 302 of the ice making chamber 300, the pressure loss of the cold air is small, and the cold airflow can be more efficiently introduced into the inflow port 302. For example, in the aforementioned Patent Documents 1 and 3, the air blowing direction of the blower is horizontal, and the cold air supply opening to the ice making compartment is opened above the blower, so the flow of the cold air to the ice making compartment and the blower are The air supply direction is almost vertical, which causes the problem of air-conditioning supply efficiency. However, according to the present embodiment, since the cold air pressure loss sent from the blower 54 to the ice making chamber 300 can be suppressed, the amount of cold air supplied to the ice making chamber 300 can be relatively increased, and the ice making efficiency can be improved while the section is improved. Can be effective.
例如，如本實施形態的冷凍冷藏庫100，製冰室300和冷凍室500上下排列配置，在將送風機54設定為約略與冷凍室500的流入口502相對的情況下，設置送風機54時的傾斜角度θ 2可以設定為例如15°以上-45°以下的值。如此，抑制了向製冰室300吹送的冷氣的壓力損失，並且，使送風機54的送風方向朝向製冰室300側傾斜，藉此抑制向冷凍室500的冷氣供應效率的下降。 For example, in the freezer-refrigerator 100 of the present embodiment, the ice making compartment 300 and the freezing compartment 500 are arranged side by side, and when the blower 54 is set to face the inlet 502 of the freezing compartment 500, the inclination of the blower 54 is set. The angle θ 2 can be set to, for example, a value of 15° or more to 45° or less. In this way, the pressure loss of the cold air blown into the ice making chamber 300 is suppressed, and the blowing direction of the blower 54 is inclined toward the ice making chamber 300 side, thereby suppressing the decrease in the cooling air supply efficiency to the freezing compartment 500.
此外，雖然不是要限定角度θ 2的具體的數值，不過如果角度θ 2太大就會使得朝向冷凍室500的冷氣供應效率下降，如果角度θ 2太小，則朝向製冰室300的冷氣供應效率就下降。考慮上述因素來設定送風機54的設置角度。 Further, although it is not intended to define a specific value of the angle θ 2 , if the angle θ 2 is too large, the cooling air supply efficiency toward the freezing compartment 500 is lowered, and if the angle θ 2 is too small, the cold air supply toward the ice making compartment 300 is supplied. Efficiency will drop. The set angle of the blower 54 is set in consideration of the above factors.
另外，例如，在儲存室的配置和本實施形態不同，最下面是冷凍室、其上為蔬菜室、再上面為製冰室的情況下，可以考慮向冷凍室的冷氣供應效率和製冰室的冷氣供應效率的平衡，來設定設置送風機的時候的角度θ 2。 Further, for example, in the case where the arrangement of the storage chamber is different from that of the present embodiment, in the case where the lowermost compartment is the freezer compartment, the vegetable compartment is above, and the upper is the ice making compartment, the cooling air supply efficiency to the freezing compartment and the ice making compartment can be considered. The balance of the air-conditioning supply efficiency is used to set the angle θ 2 when the blower is set.
繼之，說明本實施形態的製冰動作。 Next, the ice making operation of this embodiment will be described.

Hereinafter, the ice making operation and the flow of the cold air related to the ice making operation will be described with reference to FIGS. 3 and 12.
被冷卻器53冷卻的空氣的一部分，被送風機54吹送， 從流入口302流入製冰室300。如前述，送風機54的送風方向相對於流入口302的開口面有角度θ 2的傾斜，所以吹到流入口302的冷氣的壓力損失比傳統的還要低。 A part of the air cooled by the cooler 53 is blown by the blower 54, The inflow compartment 300 flows into the ice making compartment 300. As described above, the blowing direction of the blower 54 is inclined at an angle θ 2 with respect to the opening surface of the inflow port 302, so that the pressure loss of the cold air blown to the inflow port 302 is lower than that of the conventional one.
來自流入口302的冷氣，首先，流入導風盤2的入口側風路31。在入口側風路31中，因為擴大部21a而使得冷氣的流路截面積比起在流入口302的流路截面積更大。詳言之，入口側風路31的流路截面積擴大，以使得冷氣的流速盡量接近0(零)。因此，導風盤2內的冷氣大致上是流速接近0的狀態。 The cold air from the inflow port 302 first flows into the inlet side air passage 31 of the air guiding disc 2. In the inlet side air passage 31, the flow passage sectional area of the cold air is larger than the flow passage sectional area of the flow inlet 302 because of the enlarged portion 21a. In detail, the flow path cross-sectional area of the inlet side air passage 31 is enlarged so that the flow rate of the cold air is as close as possible to 0 (zero). Therefore, the cold air in the air guide disk 2 is substantially in a state where the flow velocity is close to zero.
流入入口側風路31的冷氣，分岔到第一風路32和第二風路33。然後，第一風路32和第二風路33內的冷氣，透過設置在導風盤2的底板22的吹出口23，提供到製冰皿1。相對於從流入口302供應冷氣的導風盤2的上方側，導風盤2的下方側(製冰皿1側)是相對的低壓，所以，導風盤2的冷風氣路3的冷氣，透過吹出口23往低壓側的製冰皿1方向流。 The cold air that has flowed into the inlet side air passage 31 is branched to the first air passage 32 and the second air passage 33. Then, the cold air in the first air passage 32 and the second air passage 33 is supplied to the ice tray 1 through the air outlet 23 provided in the bottom plate 22 of the air guide tray 2. The lower side of the air guiding disc 2 (the side of the ice making tray 1) is a relatively low pressure with respect to the upper side of the air guiding disc 2 that supplies cold air from the inflow port 302, so that the cold air of the cold air path 3 of the air guiding disc 2 is The air is blown through the air outlet 23 toward the ice tray 1 on the low pressure side.
如上述，導風盤2的吹出口23的開口面積被調整為使得對應的製冰皿1的冰室11的製冰時間變為約略一致，使得各冰室11能以大致相同的進度進行製冰。 As described above, the opening area of the air outlet 23 of the air deflector 2 is adjusted such that the ice making time of the ice chamber 11 of the corresponding ice tray 1 becomes approximately uniform, so that the ice chambers 11 can be manufactured at substantially the same schedule. ice.
如12(c)圖所示，吹出口23位於製冰皿1的各冰室11斜上方，而且，吹出口23的開口面相對於製冰皿1的水面傾斜。從這樣的吹出口23吹出的冷氣，從製冰皿1的各冰室11的斜上方提供。因為設有對應於製冰皿1的各冰室11的複數個吹出口23，所以各冰室11內的水，可以用該 冰室11對應的吹出口23的冷氣作為主要的冷卻源而得以有效地冷卻。而且，各冰室11內的水藉由所供應的冷氣結成冰。 As shown in Fig. 12(c), the air outlets 23 are located obliquely above the ice chambers 11 of the ice tray 1, and the opening faces of the air outlets 23 are inclined with respect to the water surface of the ice tray 1. The cold air blown out from such an air outlet 23 is supplied from the oblique upper side of each ice chamber 11 of the ice tray 1. Since a plurality of air outlets 23 corresponding to the respective ice chambers 11 of the ice tray 1 are provided, the water in each ice chamber 11 can be used. The cold air of the air outlet 23 corresponding to the ice chamber 11 is effectively cooled as a main cooling source. Moreover, the water in each ice chamber 11 is formed into ice by the supplied cold air.
熱電堆7依據特定週期測定製冰皿1內的水的溫度，當測得的溫度達到所定溫度時，控制裝置(未圖示)就判斷為製冰皿1內已經結成冰。此時，控制裝置控制驅動裝置4，使製冰皿1反轉，以使得製冰皿1內的冰落下，將作好的冰存放在儲冰盒5中。 The thermopile 7 measures the temperature of the water in the ice tray 1 according to a specific period. When the measured temperature reaches a predetermined temperature, the control device (not shown) determines that ice has been formed in the ice tray 1. At this time, the control device controls the driving device 4 to invert the ice tray 1 so that the ice in the ice tray 1 falls, and the prepared ice is stored in the ice bank 5.
如上述，在本實施形態中，設有單一個流入口302對製冰室300吹出冷氣。而且，來自流入口302的冷氣，藉由導風盤2所形成的冷風氣路3，而從製冰皿1的上部提供至製冰皿1，藉此，直接從上部冷卻製冰皿1。如此，供應到製冰室300的冷氣全部用於從上部直接冷卻製冰皿1的直接冷卻之用，所以，相較於設置複數個流入口間接冷卻製冰皿，本發明能更有效率地製冰。 As described above, in the present embodiment, a single inlet 302 is provided to blow cold air to the ice making chamber 300. Further, the cold air from the inflow port 302 is supplied from the upper portion of the ice tray 1 to the ice tray 1 by the cold air passage 3 formed by the air deflector 2, whereby the ice tray 1 is directly cooled from the upper portion. Thus, the cold air supplied to the ice making chamber 300 is all used for direct cooling of the ice tray 1 directly from the upper portion, so that the present invention can be more efficiently performed than indirectly cooling the ice tray with a plurality of inlets. Ice making.
另外，構成為：在設置於製冰皿1的複數個冰室11分別設有對應的吹出口23，冷風氣路3內的冷氣，僅從這些些吹出口23向製冰室300提供。來自製冰皿1的冰室11上方的冷氣流量，對於製冰效率的影響大，將全部冷風氣路3內的冷氣從吹出口23向各冰室11上方提供，藉此能夠提升製冰效率。 Further, each of the plurality of ice chambers 11 provided in the ice tray 1 is provided with a corresponding air outlet 23, and the cold air in the cold air passage 3 is supplied only from the air outlets 23 to the ice making chamber 300. The flow rate of the cold air from above the ice chamber 11 of the ice tray 1 has a large influence on the ice making efficiency, and the cold air in all the cold air passages 3 is supplied from the air outlet 23 to the upper of each ice chamber 11, thereby improving the ice making efficiency. .
另外，送風機54的送風方向，在製冰室300的流入口302的開口面側，有相對於水平面特定的角度θ 2的傾斜。藉此，使得在到達製冰室300的流入口302的風路中的冷 氣的壓力損失變少，能夠使冷氣更有效率地流入流入口302。因此，相較於例如上述專利文獻1、3中所記載的在與向製冰室的流入口垂直的方向上送風，本發明能更提升製冰效率，並能提高在製冰時的節能效果。 Further, the air blowing direction of the blower 54 has an inclination of a specific angle θ 2 with respect to the horizontal plane on the opening surface side of the inflow port 302 of the ice making chamber 300. Thereby, the cold in the air path reaching the inflow port 302 of the ice making chamber 300 is caused. The pressure loss of the gas is reduced, and the cold air can be more efficiently flowed into the inflow port 302. Therefore, the present invention can improve the ice making efficiency and the energy saving effect at the time of ice making, as compared with, for example, the air blowing in the direction perpendicular to the inflow port of the ice making chamber as described in the above Patent Documents 1 and 3. .
另外，在導風盤2中，在與流入口302連接的入口側風路31中，其流路截面積擴大為大於流入口302中的流路截面積。更詳細地說，擴大在冷風氣路3入口側的流路截面積，以使得冷風氣路3中的冷氣的流速盡量接近0。藉此，對製冰皿1的各冰室11提供的冷氣的流量，可以由導風盤2上方和下方的壓力差距和吹出口23的開口面積來決定。因此，藉由調整該壓力差距和吹出口23的開口面積，就可以將各冰室11更均一地冷卻。 Further, in the air guide tray 2, in the inlet side air passage 31 connected to the inflow port 302, the flow path cross-sectional area is enlarged to be larger than the flow path cross-sectional area in the inflow port 302. More specifically, the flow path cross-sectional area on the inlet side of the cold air passage 3 is enlarged so that the flow rate of the cold air in the cold air passage 3 is as close as possible to zero. Thereby, the flow rate of the cold air supplied to each ice chamber 11 of the ice tray 1 can be determined by the pressure difference between the upper and lower sides of the air guide disk 2 and the opening area of the air outlet 23. Therefore, by adjusting the pressure difference and the opening area of the air outlet 23, each ice chamber 11 can be more uniformly cooled.
另外，使吹出口23的開口面，相對於製冰皿1的水面傾斜角度θ 1。因此，除了調整吹出口23的開口面積，還可以藉由調整該角度θ 1，使得對製冰皿1的各冰室11進行更均一的冷卻。 Moreover, the opening surface of the air outlet 23 is inclined by an angle θ1 with respect to the water surface of the ice tray 1. Therefore, in addition to adjusting the opening area of the air outlet 23, the ice chambers 11 of the ice tray 1 can be more uniformly cooled by adjusting the angle θ1.
另外，構成為可將製冰皿1對製冰裝置310裝卸。因此，使用者可以拿下製冰皿1進行清潔等，能使得使用更佳方便。 Further, the ice tray 1 can be attached to and detached from the ice making device 310. Therefore, the user can take down the ice tray 1 for cleaning, etc., which makes the use more convenient.
